For me, the only way to reset the failed cherry-pick-attempt was
git reset --hard HEAD
You didn't specify how the order is determined, but this will give you a rank value in MySQL:
SELECT t.*,
@rownum := @rownum +1 AS rank
FROM TBL_FOO t
JOIN (SELECT @rownum := 0) r
WHERE t.name = 'sarmen'
Then you can pick out what rows you want, based on the rank value.
Try the library SimpleDraweeView
<com.facebook.drawee.view.SimpleDraweeView
android:id="@+id/badge_image"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
and now you can simply do:
final Uri uri = Uri.parse(post.getImageUrl());
I don't think there is a way to do that out-of-the-box. A possibly cleaner solution would be:
Stream.of(objects)
.filter(c -> c instanceof Client)
.map(c -> (Client) c)
.map(Client::getID)
.forEach(System.out::println);
or, as suggested in the comments, you could use the cast
method - the former may be easier to read though:
Stream.of(objects)
.filter(Client.class::isInstance)
.map(Client.class::cast)
.map(Client::getID)
.forEach(System.out::println);
The real answer is you need to set the escape character to '\': SET ESCAPE ON
The problem may have occurred either because escaping was disabled, or the escape character was set to something other than '\'. The above statement will enable escaping and set it to '\'.
None of the other answers previously posted actually answer the original question. They all work around the problem but don't resolve it.
As @user786653 suggested, use the xxd(1)
program:
xxd -r -p input.txt output.bin
The sheer <img ... width="50%"> said above, did work on my Github Readme.md document.
However my real issue was, that the image was inside a table cell, just compressing the text in the beside cell. So the other way was to set columns width in Markdown tables, but the solutions did not really seem enough markdownish for my morning.
At last I solved both problems by simply forcing the beside text cell with as much "& nbsp;" as I needed.
I hope this helps. Bye and thanks everybody.
CSS 3
divContainer input[type="text"] {
width:150px;
}
CSS2 add a class "text" to the text inputs then in your css
.divContainer.text{
width:150px;
}
You can even use FileOutputStream
to get what you need. This is how it can be done,
File file = new File(Environment.getExternalStorageDirectory(), "abc.txt");
FileOutputStream fOut = new FileOutputStream(file, true);
OutputStreamWriter osw = new OutputStreamWriter(fOut);
osw.write("whatever you need to write");
osw.flush();
osw.close();
The way you have used the HTML syntax is problematic.
This is how the syntax should be
style="property1:value1;property2:value2"
In your case, this will be the way to do
<h2 style="text-align :center; font-family :tahoma" >TITLE</h2>
A further example would be as follows
<div class ="row">
<button type="button" style= "margin-top : 20px; border-radius: 15px"
class="btn btn-primary">View Full Profile</button>
</div>
Lazy loading images by attaching listener to scroll events or by making use of setInterval is highly non-performant as each call to getBoundingClientRect() forces the browser to re-layout the entire page and will introduce considerable jank to your website.
Use Lozad.js (just 569 bytes with no dependencies), which uses IntersectionObserver to lazy load images performantly.
Some data I would leave in HTML, but it is better to define the src in CSS:
<img alt="Test Alt text" title="Title text" class="logo">
.logo {
content:url('../images/logo.png');
}
I was happy at my textpad and ecplise world until i had to start working with servers running under linux. Remote scripting and set up of config files was needed!
It was hard at the begining but now i can easily set up and tune up my servers.

When you use git push origin :staleStuff
, it automatically removes origin/staleStuff
, so when you ran git remote prune origin
, you have pruned some branch that was removed by someone else. It's more likely that your co-workers now need to run git prune
to get rid of branches you have removed.
So what exactly git remote prune
does? Main idea: local branches (not tracking branches) are not touched by git remote prune
command and should be removed manually.
Now, a real-world example for better understanding:
You have a remote repository with 2 branches: master
and feature
. Let's assume that you are working on both branches, so as a result you have these references in your local repository (full reference names are given to avoid any confusion):
refs/heads/master
(short name master
)refs/heads/feature
(short name feature
)refs/remotes/origin/master
(short name origin/master
)refs/remotes/origin/feature
(short name origin/feature
)Now, a typical scenario:
feature
, merges it into master
and removes feature
branch from remote repository.git fetch
(or git pull
), no references are removed from your local repository, so you still have all those 4 references.git remote prune origin
.feature
branch no longer exists, so refs/remotes/origin/feature
is a stale branch which should be removed. refs/heads/feature
, because git remote prune
does not remove any refs/heads/*
references.It is possible to identify local branches, associated with remote tracking branches, by branch.<branch_name>.merge
configuration parameter. This parameter is not really required for anything to work (probably except git pull
), so it might be missing.
(updated with example & useful info from comments)
The most likely culprit is Microsoft Internet Information Server. You can stop the service from the command line on Windows 7/Vista:
net stop was /y
or XP:
net stop iisadmin /y
read this http://www.sitepoint.com/unblock-port-80-on-windows-run-apache/
The best practice for this sort of situation is to create a method that hold all the logics, and call the method in both events, rather than calling an event from another event;
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
LogicMethod()
End Sub
Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
LogicMethod()
End Sub
Private Sub LogicMethod()
// All your logic goes here
End Sub
In case you need the properties of the EventArgs (e), you can easily pass it through parameters in your method, that will avoid errors if ever the sender is of different types. But that won't be a problem in your case, as both senders are of type Button.
defaults write org.R-project.R force.LANG en_US.UTF-8
For someone runs R in a docker environment (under root), try to run R with below command,
LC_ALL=C.UTF-8 R
# instead of just `R`
The maximum SqlDbType.VarChar size is 2147483647.
If you would use a generic oledb connection instead of sql, I found here there is also a LongVarChar datatype. Its max size is 2147483647.
cmd.Parameters.Add("@blah", OleDbType.LongVarChar, -1).Value = "very big string";
You can use wc -l
to figure out the total # of lines.
You can then combine head
and tail
to get at the range you want. Let's assume the log is 40,000 lines, you want the last 1562 lines, then of those you want the first 838. So:
tail -1562 MyHugeLogFile.log | head -838 | ....
Or there's probably an easier way using sed
or awk
.
I just used this:

fbCommand.CommandType = CommandType.StoredProcedure;
object result = fbCommand.ExecuteScalar(); // ExecuteScalar fails on null
if (result.GetType() != typeof(DBNull))
{
terminalID = (int?)result;
}
}
return terminalID;

Suppose your "Don't Check" list is on Sheet2 in cells A1:A100
, say, and your current client IDs are in Sheet1 in Column A.
What you would do is:
Conditional Formatting

=ISNUMBER(MATCH($A1,Sheet2!$A$1:$A$100,0))
and select how you want those rows formattedAnd that should do the trick.
SELECT DATE_FORMAT(somedate, "%d/%m/%Y") AS formatted_date
..........
ORDER BY formatted_date DESC

As of version 1.5.1, I'm able to access all the sockets in a namespace with:
var socket_ids = Object.keys(io.of('/namespace').sockets);
socket_ids.forEach(function(socket_id) {
var socket = io.of('/namespace').sockets[socket_id];
if (socket.connected) {
// Do something...
}
});
For some reason, they're using a plain object instead of an array to store the socket IDs.
You can't bind an event to the element before it exists, so you should do it in the onload
event:
<html>
<head>
<script type="text/javascript">
window.onload = function() {
document.getElementById('foo').addEventListener('click', function (e) {
var img = document.createElement('img');
img.setAttribute('src', 'http://blog.stackoverflow.com/wp-content/uploads/stackoverflow-logo-300.png');
e.target.appendChild(img);
});
};
</script>
</head>
<body>
<img id="foo" src="http://soulsnatcher.bplaced.net/LDRYh.jpg" alt="unfinished bingo card" />
</body>
</html>
Naturally, my approach was to loop through the first array once and check the index of each value in the second array. If the index is > -1
, then push
it onto the returned array.
?Array.prototype.diff = function(arr2) {
var ret = [];
for(var i in this) {
if(arr2.indexOf(this[i]) > -1){
ret.push(this[i]);
}
}
return ret;
};
?
My solution doesn't use two loops like others do so it may run a bit faster. If you want to avoid using for..in
, you can sort both arrays first to reindex all their values:
Array.prototype.diff = function(arr2) {
var ret = [];
this.sort();
arr2.sort();
for(var i = 0; i < this.length; i += 1) {
if(arr2.indexOf(this[i]) > -1){
ret.push(this[i]);
}
}
return ret;
};
Usage would look like:
var array1 = ["cat", "sum","fun", "run", "hut"];
var array2 = ["bat", "cat","dog","sun", "hut", "gut"];
console.log(array1.diff(array2));
If you have an issue/problem with extending the Array prototype, you could easily change this to a function.
var diff = function(arr, arr2) {
And you'd change anywhere where the func originally said this
to arr2
.
In TypeScript if we are declaring object then we'd use the following syntax:
[access modifier] variable name : { /* structure of object */ }
For example:
private Object:{ Key1: string, Key2: number }
Another solution is to run logic via sequential executor nsynjs. It reads file line-by-line using node readline module, and it doesn't use promises or recursion, therefore not going to fail on large files. Here is how the code will looks like:
var nsynjs = require('nsynjs');
var textFile = require('./wrappers/nodeReadline').textFile; // this file is part of nsynjs
function process(textFile) {
var fh = new textFile();
fh.open('path/to/file');
var s;
while (typeof(s = fh.readLine(nsynjsCtx).data) != 'undefined')
console.log(s);
fh.close();
}
var ctx = nsynjs.run(process,{},textFile,function () {
console.log('done');
});
Code above is based on this exampe: https://github.com/amaksr/nsynjs/blob/master/examples/node-readline/index.js

This was the first result on google, when I was looking how to rename a user, so:
ALTER USER <username> WITH PASSWORD '<new_password>'; -- change password
ALTER USER <old_username> RENAME TO <new_username>; -- rename user
A couple of other commands helpful for user management:
CREATE USER <username> PASSWORD '<password>' IN GROUP <group>;
DROP USER <username>;
Move user to another group
ALTER GROUP <old_group> DROP USER <username>;
ALTER GROUP <new_group> ADD USER <username>;
JSON is similar to other data formats like XML - if you need to transmit more data, you just send more data. There's no inherent size limitation to the JSON request. Any limitation would be set by the server parsing the request. (For instance, ASP.NET has the "MaxJsonLength" property of the serializer.)
First install beautiful soup version 4. write command in the terminal window:

You can plot multiple subplots of multiple pandas data frames using matplotlib with a simple trick of making a list of all data frame. Then using the for loop for plotting subplots.
Working code:
import matplotlib.pyplot as plt
import pandas as pd
import numpy as np
# dataframe sample data
df1 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
df2 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
df3 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
df4 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
df5 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
df6 = pd.DataFrame(np.random.rand(10,2)*100, columns=['A', 'B'])
#define number of rows and columns for subplots
nrow=3
ncol=2
# make a list of all dataframes
df_list = [df1 ,df2, df3, df4, df5, df6]
fig, axes = plt.subplots(nrow, ncol)
# plot counter
count=0
for r in range(nrow):
for c in range(ncol):
df_list[count].plot(ax=axes[r,c])
count=+1
Using this code you can plot subplots in any configuration. You need to just define number of rows nrow
and number of columns ncol
. Also, you need to make list of data frames df_list
which you wanted to plot.
This is my version of the extension methods posted here and in similar questions. This validates the ticks value in an easy to read way and preserves the DateTimeKind of the original DateTime instance. (This has subtle but relevant side effects when storing to a database like MongoDB.)
If the true goal is to truncate a DateTime to a specified value (i.e. Hours/Minutes/Seconds/MS) I recommend implementing this extension method in your code instead. It ensures that you can only truncate to a valid precision and it preserves the important DateTimeKind metadata of your original instance:
public static DateTime Truncate(this DateTime dateTime, long ticks)
{
bool isValid = ticks == TimeSpan.TicksPerDay
|| ticks == TimeSpan.TicksPerHour
|| ticks == TimeSpan.TicksPerMinute
|| ticks == TimeSpan.TicksPerSecond
|| ticks == TimeSpan.TicksPerMillisecond;
// https://stackoverflow.com/questions/21704604/have-datetime-now-return-to-the-nearest-second
return isValid
? DateTime.SpecifyKind(
new DateTime(
dateTime.Ticks - (dateTime.Ticks % ticks)
),
dateTime.Kind
)
: throw new ArgumentException("Invalid ticks value given. Only TimeSpan tick values are allowed.");
}
Then you can use the method like this:
DateTime dateTime = DateTime.UtcNow.Truncate(TimeSpan.TicksPerMillisecond);
dateTime.Kind => DateTimeKind.Utc
Just generalising the query if you want to work with any given date instead of current date:
SELECT Table.date
FROM Table
WHERE Table.date > '2020-01-01'::date - interval '10 day'
You need to use a directed graph instead of a graph, i.e.
G = nx.DiGraph()
Then, create a list of the edge colors you want to use and pass those to nx.draw
(as shown by @Marius).
Putting this all together, I get the image below. Still not quite the other picture you show (I don't know where your edge weights are coming from), but much closer! If you want more control of how your output graph looks (e.g. get arrowheads that look like arrows), I'd check out NetworkX with Graphviz.
My solution was to use a short nickname (less than 31 characters) and then write the entire name in cell 0.
None of solutions on this page works correctly and universally for all levels and long (wrapped) paragraphs. It’s really tricky to achieve a consistent indentation due to variable size of marker (1., 1.2, 1.10, 1.10.5, …); it can’t be just “faked,” not even with a precomputed margin/padding for each possible indentation level.
I finally figured out a solution that actually works and doesn’t need any JavaScript.
It’s tested on Firefox 32, Chromium 37, IE 9 and Android Browser. Doesn't work on IE 7 and previous.
CSS:
ol {
list-style-type: none;
counter-reset: item;
margin: 0;
padding: 0;
}
ol > li {
display: table;
counter-increment: item;
margin-bottom: 0.6em;
}
ol > li:before {
content: counters(item, ".") ". ";
display: table-cell;
padding-right: 0.6em;
}
li ol > li {
margin: 0;
}
li ol > li:before {
content: counters(item, ".") " ";
}
This worked for me. But make sure to load the jquery.js before the preferred dataTable.js file. Cheers!
<script type="text/javascript" src="~/Scripts/jquery.js"></script>
<script type="text/javascript" src="~/Scripts/data-table/jquery.dataTables.js"></script>
<script>$(document).ready(function () {
$.noConflict();
var table = $('# your selector').DataTable();
});</script>
If jQuery above does not work, then try
$(Object.Item).length
Use parse_url()
like this:
function url(){
if(isset($_SERVER['HTTPS'])){
$protocol = ($_SERVER['HTTPS'] && $_SERVER['HTTPS'] != "off") ? "https" : "http";
}
else{
$protocol = 'http';
}
return $protocol . "://" . parse_url($_SERVER['REQUEST_URI'], PHP_URL_HOST);
}
Here is another shorter option:
function url(){
$pu = parse_url($_SERVER['REQUEST_URI']);
return $pu["scheme"] . "://" . $pu["host"];
}
The easy way is to make a for
where you verify if the atrrtibute name
of the custom object have the desired string
for(Datapoint d : dataPointList){
if(d.getName() != null && d.getName().contains(search))
//something here
}
I think this helps you.
There are two open source implementations.
Apache Solr has ConcurrentLRUCache: https://lucene.apache.org/solr/3_6_1/org/apache/solr/util/ConcurrentLRUCache.html
There's an open source project for a ConcurrentLinkedHashMap: http://code.google.com/p/concurrentlinkedhashmap/
According to: https://docs.npmjs.com/files/folders
- Local install (default): puts stuff in ./node_modules of the current package root.
- Global install (with -g): puts stuff in /usr/local or wherever node is installed.
- Install it locally if you're going to require() it.
- Install it globally if you're going to run it on the command line. -> If you need both, then install it in both places, or use npm link.
prefix Configuration
The prefix config defaults to the location where node is installed. On most systems, this is
/usr/local
. On windows, this is the exact location of the node.exe binary.
The docs might be a little outdated, but they explain why global installs can end up in different directories:
(dev) go|c:\srv> npm config ls -l | grep prefix
; prefix = "C:\\Program Files\\nodejs" (overridden)
prefix = "C:\\Users\\bjorn\\AppData\\Roaming\\npm"
Based on the other answers, it may seem like the override is now the default location on Windows, and that I may have installed my office version prior to this override being implemented.
This also suggests a solution for getting all team members to have globals stored in the same absolute path relative to their PC, i.e. (run as Administrator):
mkdir %PROGRAMDATA%\npm
setx PATH "%PROGRAMDATA%\npm;%PATH%" /M
npm config set prefix %PROGRAMDATA%\npm
open a new cmd.exe window and reinstall all global packages.
Explanation (by lineno.):
setx .. /M
to set the
system path (under HKEY_LOCAL_MACHINE). This is what requires you to run
this in a shell with administrator permissions.npm
to use this new path. (Note: folder isn't visible in %PATH% in
this shell, so you must open a new window).Cluster differs from Cloud and Grid in that a cluster is a group of computers connected by a local area network (LAN), whereas cloud and grid are more wide scale and can be geographically distributed. Another way to put it is to say that a cluster is tightly coupled, whereas a Grid or a cloud is loosely coupled. Also, clusters are made up of machines with similar hardware, whereas clouds and grids are made up of machines with possibly very different hardware configurations.
To know more about cloud computing, I recommend reading this paper: «Above the Clouds: A Berkeley View of Cloud Computing», Michael Armbrust, Armando Fox, Rean Griffith, Anthony D. Joseph, Randy H. Katz, Andrew Konwinski, Gunho Lee, David A. Patterson, Ariel Rabkin, Ion Stoica and Matei Zaharia. The following is an abstract from the above paper:
Cloud Computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the datacenters that provide those services. The services themselves have long been referred to as Software as a Service (SaaS). The datacenter hardware and software is what we call a Cloud. When a Cloud is made available in a pay-as-you-go manner to the general public, we call it a Public Cloud; the service being sold is Utility Computing. We use the term Private Cloud to refer to internal datacenters of a business or other organization, not made available to the general public. Thus, Cloud Computing is the sum of SaaS and Utility Computing, but does not include Private Clouds. People can be users or providers of SaaS, or users or providers of Utility Computing.
The difference between a cloud and a grid can be expressed as below:
Resource distribution: Cloud computing is a centralized model whereas grid computing is a decentralized model where the computation could occur over many administrative domains.
Ownership: A grid is a collection of computers which is owned by multiple parties in multiple locations and connected together so that users can share the combined power of resources. Whereas a cloud is a collection of computers usually owned by a single party.
Examples of Clouds: Amazon Web Services (AWS), Google App Engine.
Examples of Grids: FutureGrid.
Examples of cloud computing services: Dropbox, Gmail, Facebook, Youtube, RapidShare.

The 2017 answer is: Use the date and time classes introduced in Java 8 (and also backported to Java 6 and 7 in the ThreeTen Backport).
If you want to interpret the date-time string in the computer’s time zone:
long millisSinceEpoch = LocalDateTime.parse(myDate, DateTimeFormatter.ofPattern("uuuu/MM/dd HH:mm:ss"))
.atZone(ZoneId.systemDefault())
.toInstant()
.toEpochMilli();
If another time zone, fill that zone in instead of ZoneId.systemDefault()
. If UTC, use
long millisSinceEpoch = LocalDateTime.parse(myDate, DateTimeFormatter.ofPattern("uuuu/MM/dd HH:mm:ss"))
.atOffset(ZoneOffset.UTC)
.toInstant()
.toEpochMilli();
var month = 0; // January
var d = new Date(2008, month + 1, 0);
alert(d); // last day in January
IE 6: Thu Jan 31 00:00:00 CST 2008
IE 7: Thu Jan 31 00:00:00 CST 2008
IE 8: Beta 2: Thu Jan 31 00:00:00 CST 2008
Opera 8.54: Thu, 31 Jan 2008 00:00:00 GMT-0600
Opera 9.27: Thu, 31 Jan 2008 00:00:00 GMT-0600
Opera 9.60: Thu Jan 31 2008 00:00:00 GMT-0600

Google Chrome 0.2.149.30: Thu Jan 31 2008 00:00:00 GMT-0600 (Canada Central Standard Time)
Safari for Windows 3.1.2: Thu Jan 31 2008 00:00:00 GMT-0600 (Canada Central Standard Time)
Output differences are due to differences in the toString()
implementation, not because the dates are different.
Of course, just because the browsers identified above use 0 as the last day of the previous month does not mean they will continue to do so, or that browsers not listed will do so, but it lends credibility to the belief that it should work the same way in every browser.

, TO_NUMBER(TO_CHAR(B.last_update_date, 'YYYYMM')) as UPD_DATE

One simple query will do it:

You need to map attributes to aesthetics (colours within the aes statement) to produce a legend.
cols <- c("LINE1"="#f04546","LINE2"="#3591d1","BAR"="#62c76b")
ggplot(data=data,aes(x=a)) +
geom_bar(stat="identity", aes(y=h, fill = "BAR"),colour="#333333")+ #green
geom_line(aes(y=b,group=1, colour="LINE1"),size=1.0) + #red
geom_point(aes(y=b, colour="LINE1"),size=3) + #red
geom_errorbar(aes(ymin=d, ymax=e, colour="LINE1"), width=0.1, size=.8) +
geom_line(aes(y=c,group=1,colour="LINE2"),size=1.0) + #blue
geom_point(aes(y=c,colour="LINE2"),size=3) + #blue
geom_errorbar(aes(ymin=f, ymax=g,colour="LINE2"), width=0.1, size=.8) +
scale_colour_manual(name="Error Bars",values=cols) + scale_fill_manual(name="Bar",values=cols) +
ylab("Symptom severity") + xlab("PHQ-9 symptoms") +
ylim(0,1.6) +
theme_bw() +
theme(axis.title.x = element_text(size = 15, vjust=-.2)) +
theme(axis.title.y = element_text(size = 15, vjust=0.3))
I understand where Roland is coming from, but since this is only 3 attributes, and complications arise from superimposing bars and error bars this may be reasonable to leave the data in wide format like it is. It could be slightly reduced in complexity by using geom_pointrange.
To change the background color for the error bars legend in the original, add + theme(legend.key = element_rect(fill = "white",colour = "white"))
to the plot specification. To merge different legends, you typically need to have a consistent mapping for all elements, but it is currently producing an artifact of a black background for me. I thought guide = guide_legend(fill = NULL,colour = NULL)
would set the background to null for the legend, but it did not. Perhaps worth another question.
ggplot(data=data,aes(x=a)) +
geom_bar(stat="identity", aes(y=h,fill = "BAR", colour="BAR"))+ #green
geom_line(aes(y=b,group=1, colour="LINE1"),size=1.0) + #red
geom_point(aes(y=b, colour="LINE1", fill="LINE1"),size=3) + #red
geom_errorbar(aes(ymin=d, ymax=e, colour="LINE1"), width=0.1, size=.8) +
geom_line(aes(y=c,group=1,colour="LINE2"),size=1.0) + #blue
geom_point(aes(y=c,colour="LINE2", fill="LINE2"),size=3) + #blue
geom_errorbar(aes(ymin=f, ymax=g,colour="LINE2"), width=0.1, size=.8) +
scale_colour_manual(name="Error Bars",values=cols, guide = guide_legend(fill = NULL,colour = NULL)) +
scale_fill_manual(name="Bar",values=cols, guide="none") +
ylab("Symptom severity") + xlab("PHQ-9 symptoms") +
ylim(0,1.6) +
theme_bw() +
theme(axis.title.x = element_text(size = 15, vjust=-.2)) +
theme(axis.title.y = element_text(size = 15, vjust=0.3))
To get rid of the black background in the legend, you need to use the override.aes
argument to the guide_legend
. The purpose of this is to let you specify a particular aspect of the legend which may not be being assigned correctly.
ggplot(data=data,aes(x=a)) +
geom_bar(stat="identity", aes(y=h,fill = "BAR", colour="BAR"))+ #green
geom_line(aes(y=b,group=1, colour="LINE1"),size=1.0) + #red
geom_point(aes(y=b, colour="LINE1", fill="LINE1"),size=3) + #red
geom_errorbar(aes(ymin=d, ymax=e, colour="LINE1"), width=0.1, size=.8) +
geom_line(aes(y=c,group=1,colour="LINE2"),size=1.0) + #blue
geom_point(aes(y=c,colour="LINE2", fill="LINE2"),size=3) + #blue
geom_errorbar(aes(ymin=f, ymax=g,colour="LINE2"), width=0.1, size=.8) +
scale_colour_manual(name="Error Bars",values=cols,
guide = guide_legend(override.aes=aes(fill=NA))) +
scale_fill_manual(name="Bar",values=cols, guide="none") +
ylab("Symptom severity") + xlab("PHQ-9 symptoms") +
ylim(0,1.6) +
theme_bw() +
theme(axis.title.x = element_text(size = 15, vjust=-.2)) +
theme(axis.title.y = element_text(size = 15, vjust=0.3))

In java we can read input values in 6 ways:
- Scanner class: present in java.util.*; package and it has many methods, based your input types you can utilize those methods. a. nextInt() b. nextLong() c. nextFloat() d. nextDouble() e. next() f. nextLine(); etc...
import java.util.Scanner;
public class MyClass {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter a :");
int a = sc.nextInt();
System.out.println("Enter b :");
int b = sc.nextInt();
int c = a + b;
System.out.println("Result: "+c);
}
}
- BufferedReader class: present in java.io.*; package & it has many method, to read the value from the keyboard use "readLine()" : this method reading one line at a time.
import java.io.BufferedReader;
import java.io.*;
public class MyClass {
public static void main(String args[]) throws IOException {
BufferedReader br = new BufferedReader(new BufferedReader(new InputStreamReader(System.in)));
System.out.println("Enter a :");
int a = Integer.parseInt(br.readLine());
System.out.println("Enter b :");
int b = Integer.parseInt(br.readLine());
int c = a + b;

Try to turn off your firewall, it works for me
. It seems that android studio wants to download some dependencies and our firewall prevents it from downloading it, just be aware that turning your firewall off may lower the security of your computer
. If you have more time you can manually allow your android studio to bypass your firewall, this way you can turn on your firewall while allowing android studio to download anything that it wants.
Discord doesn't allow colored text. Though, currently, you have two options to "mimic" colored text.
Discord supports Markdown and uses highlight.js to highlight code-blocks.
Some programming languages have specific color outputs from highlight.js and can be used to mimic colored output.
To use code-blocks, send a normal message in this format (Which follows Markdown's standard format).
```language
message
```
Languages that currently reproduce nice colors: prolog (red/orange), css (yellow).
Discord now supports Embeds and Webhooks, which can be used to display colored blocks, they also support markdown. For documentation on how to use Embeds, please read your lib's documentation.
Specify the Class Card for the constructor-:
void Card::Card(Card::Rank rank, Card::Suit suit) {
And also define the default constructor and destructor.
On top of @unutbu answer, you could coerce pandas numpy object array to native (float64) type, something along the line
import pandas as pd
pd.to_numeric(df['tester'], errors='coerce')
Specify errors='coerce' to force strings that can't be parsed to a numeric value to become NaN. Column type would be dtype: float64
, and then isnan
check should work
this method worked for me
First, put the line below at the beginning of your controller:
use File;
below namespace in your php file Second:
$destinationPath = 'your_path';
File::delete($destinationPath.'/your_file');
$destinationPath --> the folder inside folder public.
DateTime
doesn't have a default key as an input. The default key should be an input to the Column
function. Try this:
import datetime
from sqlalchemy import Column, Integer, DateTime
from sqlalchemy.ext.declarative import declarative_base
Base = declarative_base()
class Test(Base):
__tablename__ = 'test'
id = Column(Integer, primary_key=True)
created_date = Column(DateTime, default=datetime.datetime.utcnow)
It is all but satisfying, isn't it? The easiest way I have found to specify when setting the context, e.g.:
sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})
This should take care of 90% of standard plotting usage. If you want ticklabels smaller than axes labels, set the 'axes.labelsize' to the smaller (ticklabel) value and specify axis labels (or other custom elements) manually, e.g.:
axs.set_ylabel('mylabel',size=6)
you could define it as a function and load it in your scripts so you don't have to remember your standard numbers, or call it every time.
def set_pubfig:
sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})
Of course you can use configuration files, but I guess the whole idea is to have a simple, straightforward method, which is why the above works well.
Note: If you specify these numbers, specifying font_scale
in sns.set_context
is ignored for all specified font elements, even if you set it.
Another solution, You can just iterate over the object keys like so, Note: you must use an instantiated object with existing properties:
printTypeNames<T>(obj: T) {
const objectKeys = Object.keys(obj) as Array<keyof T>;
for (let key of objectKeys)
{
console.log('key:' + key);
}
}
In Spring 4 Web MVC. You can use @SessionAttribute
in the method with @SessionAttributes
in Controller level
@Controller
@SessionAttributes("SessionKey")
public class OrderController extends BaseController {
GetMapping("/showOrder")
public String showPage(@SessionAttribute("SessionKey") SearchCriteria searchCriteria) {
// method body
}
I solved this on 12.10 by installing libssl-dev.
sudo apt-get install libssl-dev
I think the best way to solve this problem is:
l = [1, 2, 3, 0, 0, 1]
while 0 in l:
l.remove(0)
Instead of iterating over list I remove 0
until there aren't any 0
in list

The newest, most recent, up to date answer
This post is really old (it's 7 years old when I answered it), so no one of the other answers used the new and recommended way, which is HttpClient
class.
HttpClient
is considered the new API and it should replace the old ones (WebClient
and WebRequest
)
string url = "page url";
HttpClient client = new HttpClient();
using (HttpResponseMessage response = client.GetAsync(url).Result)
{
using (HttpContent content = response.Content)
{
string result = content.ReadAsStringAsync().Result;
}
}
for more information about how to use the HttpClient
class (especially in async cases), you can refer this question
NOTE 1: If you want to use async/await
string url = "page url";
HttpClient client = new HttpClient(); // actually only one object should be created by Application
using (HttpResponseMessage response = await client.GetAsync(url))
{
using (HttpContent content = response.Content)
{
string result = await content.ReadAsStringAsync();
}
}
NOTE 2: If use C# 8 features
string url = "page url";
HttpClient client = new HttpClient();
using HttpResponseMessage response = await client.GetAsync(url);
using HttpContent content = response.Content;
string result = await content.ReadAsStringAsync();
I know this has already been answered, but if you end doing this a lot, regular expressions may be a better way to go:
>>> import re
>>> re.sub(r'\s', '', string).split(',')
['blah', 'lots', 'of', 'spaces', 'here']
The \s
matches any whitespace character, and we just replace it with an empty string ''
. You can find more info here: http://docs.python.org/library/re.html#re.sub
The keypad
will allow the keyboard of the user's terminal to allow for function keys to be interpreted as a single value (i.e. no escape sequence).
As stated in the man page:
The keypad option enables the keypad of the user's terminal. If enabled (bf is TRUE), the user can press a function key (such as an arrow key) and wgetch returns a single value representing the function key, as in KEY_LEFT. If disabled (bf is FALSE), curses does not treat function keys specially and the program has to interpret the escape sequences itself. If the keypad in the terminal can be turned on (made to transmit) and off (made to work locally), turning on this option causes the terminal keypad to be turned on when wgetch is called. The default value for keypad is false.
If you want to make them a lot bigger, like for multiple lines of input, you may want to use a textarea tag instead of the input tag. This allows you to put in number of rows and columns you want on your textarea without messing with css (e.g. <textarea rows="2" cols="25"></textarea>
).
Text areas are resizable by default. If you want to disable that, just use the resize css rule:
#signin textarea {
resize: none;
}
A simple solution to your question about default text that disappears when the user clicks is to use the placeholder attribute. This will work for <input>
tags as well.
<textarea rows="2" cols="25" placeholder="This is the default text"></textarea>
This text will disappear when the user enters information rather than when they click, but that is common functionality for this kind of thing.
Safe navigation operator or Existential Operator or Null Propagation Operator is supported in Angular Template. Suppose you have Component class
myObj:any = {
doSomething: function () { console.log('doing something'); return 'doing something'; },
};
myArray:any;
constructor() { }
ngOnInit() {
this.myArray = [this.myObj];
}
You can use it in template html file as following:
<div>test-1: {{ myObj?.doSomething()}}</div>
<div>test-2: {{ myArray[0].doSomething()}}</div>
<div>test-3: {{ myArray[2]?.doSomething()}}</div>
Yes, right click the project. Click Run as
then Run Configurations
. You can change the parameters passed to the JVM in the Arguments
tab in the VM Arguments
box.
That configuration can then be used as the default when running the project.
Rather than using Ctrl + K, X you can also just type prop
and then hit Tab twice.

I found James Wald's answer the closest to my solution, except instead of "File->Import->General->Existing Projects into Workspace" (which did not work for me at all) I used "File->Import->Android->Existing Android Code Into Workspace". I am using Helios, maybe your version of Eclipse does not have this quirk.
It's the "frame" or "range" clause of window functions, which are part of the SQL standard and implemented in many databases, including Teradata.
A simple example would be to calculate the average amount in a frame of three days. I'm using PostgreSQL syntax for the example, but it will be the same for Teradata:
WITH data (t, a) AS (
VALUES(1, 1),
(2, 5),
(3, 3),
(4, 5),
(5, 4),
(6, 11)
)
SELECT t, a, avg(a) OVER (ORDER BY t ROWS BETWEEN 1 PRECEDING AND 1 FOLLOWING)
FROM data
ORDER BY t
... which yields:
t a avg
----------
1 1 3.00
2 5 3.00
3 3 4.33
4 5 4.00
5 4 6.67
6 11 7.50
As you can see, each average is calculated "over" an ordered frame consisting of the range between the previous row (1 preceding
) and the subsequent row (1 following
).
When you write ROWS UNBOUNDED PRECEDING
, then the frame's lower bound is simply infinite. This is useful when calculating sums (i.e. "running totals"), for instance:
WITH data (t, a) AS (
VALUES(1, 1),
(2, 5),
(3, 3),
(4, 5),
(5, 4),
(6, 11)
)
SELECT t, a, sum(a) OVER (ORDER BY t ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW)
FROM data
ORDER BY t
yielding...
t a sum
---------
1 1 1
2 5 6
3 3 9
4 5 14
5 4 18
6 11 29
Here's another very good explanations of SQL window functions.
You can use this as an example of your problem
Map<Integer, String> map = new HashMap<>();
map.put(10, "apple");
map.put(20, "orange");
map.put(30, "banana");
map.put(40, "watermelon");
map.put(50, "dragonfruit");
// split a map into 2 List
List<Integer> resultSortedKey = new ArrayList<>();
List<String> resultValues = map.entrySet().stream()
//sort a Map by key and stored in resultSortedKey
.sorted(Map.Entry.<Integer, String>comparingByKey().reversed())
.peek(e -> resultSortedKey.add(e.getKey()))
.map(x -> x.getValue())
// filter banana and return it to resultValues
.filter(x -> !"banana".equalsIgnoreCase(x))
.collect(Collectors.toList());
resultSortedKey.forEach(System.out::println);
resultValues.forEach(System.out::println);
Use subprocess.Popen:
import subprocess
process = subprocess.Popen(['ls', '-a'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
out, err = process.communicate()
print(out)
Note that communicate blocks until the process terminates. You could use process.stdout.readline() if you need the output before it terminates. For more information see the documentation.
Try this:
Use back-ticks for NAME
CREATE TABLE `teachers` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(50) NOT NULL,
`addr` varchar(255) NOT NULL,
`phone` int(10) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
In the AndroidManifest.xml, under the application tag, you can set the theme of your choice. To customize the theme, press Ctrl + Click
on android:theme = "@style/AppTheme"
in the Android manifest file. It will open styles.xml
file where you can change the parent attribute of the style tag.
At parent=
in styles.xml
you can browse all available styles by using auto-complete inside the ""
. E.g. try parent="Theme."
with your cursor right after the .
and then pressing Ctrl + Space
.
You can also preview themes in the preview window in Android Studio.
Another possible reason is if you had some models defined in another file (not in a package) and haven't referenced that anywhere else.
For me, simply adding from .graph_model import *
to admin.py
(where graph_model.py
was the new file) fixed the problem.
The first statement depends on the context in which it is declared.
If it is declared in the global context it will create an implied global variable called "foo" which will be a variable which points to the function. Thus the function call "foo()" can be made anywhere in your javascript program.
If the function is created in a closure it will create an implied local variable called "foo" which you can then use to invoke the function inside the closure with "foo()"
EDIT:
I should have also said that function statements (The first one) are parsed before function expressions (The other 2). This means that if you declare the function at the bottom of your script you will still be able to use it at the top. Function expressions only get evaluated as they are hit by the executing code.
END EDIT
Statements 2 & 3 are pretty much equivalent to each other. Again if used in the global context they will create global variables and if used within a closure will create local variables. However it is worth noting that statement 3 will ignore the function name, so esentially you could call the function anything. Therefore
var foo = function foo() { return 5; }
Is the same as
var foo = function fooYou() { return 5; }

I have same problem after upgrading to Gradle Wrapper 5.1.rec3. I am back to Gradle 4.6
In my case problem was at context.xml file of my project.
The following from context.xml causes the java.lang.AbstractMethodError, since we didn't show the datasource factory.

username="****" password="****" maxActive="10" maxIdle="1"
maxWait="-1" removeAbandoned="true"/>
Simpy adding factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" solved the issue:

Try using Web API HttpClient
static async Task RunAsync()
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://domain.com/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
// HTTP POST
var obj = new MyObject() { Str = "MyString"};
response = await client.PostAsJsonAsync("POST URL GOES HERE?", obj );
if (response.IsSuccessStatusCode)
{
response.//.. Contains the returned content.
}
}
}
You can find more details here Web API Clients
The include_path setting works like $PATH in unix (there is a similar setting in Windows too).It contains multiple directory names, seperated by colons (:). When you include or require a file, these directories are searched in order, until a match is found or all directories are searched.
So, to make sure that your application always includes from your path if the file exists there, simply put your include dir first in the list of directories.
ini_set("include_path", "/your_include_path:".ini_get("include_path"));
This way, your include directory is searched first, and then the original search path (by default the current directory, and then PEAR). If you have no problem modifying include_path, then this is the solution for you.
My favorite for doing this is the mark.vim plugin. It allows to highlight several words in different colors simultaneously.
I made this like the following way:
try {
readImageInformation(new File(contentUri.getPath()));
} catch (IOException e) {
readImageInformation(new File(getRealPathFromURI(context,
contentUri)));
}
public static String getRealPathFromURI(Context context, Uri contentUri) {
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = context.getContentResolver().query(contentUri, proj,
null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
So basically first I try to use a file i.e. picture taken by camera and saved on SD card. This don't work for image returned by:
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
That case there is a need to convert Uri to real path by getRealPathFromURI()
function.
So the conclusion is that it depends on what type of Uri you want to convert to File.
This works for me: (i.e. I only need 2 columns of the 30+ returned by sp_help_job
)
SELECT name, current_execution_status
FROM OPENQUERY (MYSERVER,
'EXEC msdb.dbo.sp_help_job @job_name = ''My Job'', @job_aspect = ''JOB''');
Before this would work, I needed to run this:
sp_serveroption 'MYSERVER', 'DATA ACCESS', TRUE;
....to update the sys.servers
table. (i.e. Using a self-reference within OPENQUERY seems to be disabled by default.)
For my simple requirement, I ran into none of the problems described in the OPENQUERY section of Lance's excellent link.
Rossini, if you need to dynamically set those input parameters, then use of OPENQUERY becomes a little more fiddly:
DECLARE @innerSql varchar(1000);
DECLARE @outerSql varchar(1000);
-- Set up the original stored proc definition.
SET @innerSql =
'EXEC msdb.dbo.sp_help_job @job_name = '''+@param1+''', @job_aspect = N'''+@param2+'''' ;
-- Handle quotes.
SET @innerSql = REPLACE(@innerSql, '''', '''''');
-- Set up the OPENQUERY definition.
SET @outerSql =
'SELECT name, current_execution_status
FROM OPENQUERY (MYSERVER, ''' + @innerSql + ''');';
-- Execute.
EXEC (@outerSql);
I'm not sure of the differences (if any) between using sp_serveroption
to update the existing sys.servers
self-reference directly, vs. using sp_addlinkedserver
(as described in Lance's link) to create a duplicate/alias.
Note 1: I prefer OPENQUERY over OPENROWSET, given that OPENQUERY does not require the connection-string definition within the proc.
Note 2:
Having said all this: normally I would just use INSERT ... EXEC :) Yes, it's 10 mins extra typing, but if I can help it, I prefer not to jigger around with:
(a) quotes within quotes within quotes, and
(b) sys tables, and/or sneaky self-referencing Linked Server setups (i.e. for these, I need to plead my case to our all-powerful DBAs :)
However in this instance, I couldn't use a INSERT ... EXEC construct, as sp_help_job
is already using one. ("An INSERT EXEC statement cannot be nested.")
Suppress Warnings for XML comments
(not my work, but I found it useful so I've included the article & link)
http://bernhardelbl.wordpress.com/2009/02/23/suppress-warnings-for-xml-comments/
Here i will show you, how you can suppress warnings for XML comments after a Visual Studio build.
Background
If you have checked the "XML documentation file" mark in the Visual Studio project settings, a XML file containing all XML comments is created. Additionally you will get a lot of warnings also in designer generated files, because of the missing or wrong XML comments. While sometimes warnings helps us to improve and stabilize our code, getting hundreds of XML comment warnings is just a pain.
Warnings
Missing XML comment for publicly visible type or member …
XML comment on … has a param tag for ‘…’, but there is no parameter by that name Parameter ‘…’ has no matching param tag in the XML comment for ‘…’ (but other parameters do)Solution
You can suppress every warning in Visual Studio.
Right-click the Visual Studio project / Properties / Build Tab
Insert the following warning numbers in the "Suppress warnings": 1591,1572,1571,1573,1587,1570
You can run this command in Terminal:
react-native --version
This will give react-native CLI version
Or check in package.json under
"dependencies": {
"react": "16.11.0",
"react-native": "0.62.2",
}
Magic word is: isset
Validate the entry:
if(isset($manta_option['iso_format_recent_works']) && $manta_option['iso_format_recent_works'] == 1){
$theme_img = 'recent_works_thumbnail';
} else {
$theme_img = 'recent_works_iso_thumbnail';
}
Angular - equal width button group
Assuming you have an array of 'things' in your scope...
<div class="btn-group"
style="width: 100%;">
<button ng-repeat="thing in things"
class="btn btn-default"
ng-style="{width: (100/things.length)+'%'}">
{{thing}}
</button>
</div>
var counter = 0;
var listArray = [0, 1, 2, 3, 4];
function callBack() {
if (listArray.length === counter) {
console.log('All Done')
}
};
listArray.forEach(function(element){
console.log(element);
counter = counter + 1;
callBack();
});
Alternative solution (you can replace createElement with a your own element)
var mvar = $('.mbox').wrapAll(document.createElement('div')).closest('div').text();
console.log(mvar);
SELECT so.name,so.modify_date
FROM sys.objects as so
INNER JOIN INFORMATION_SCHEMA.TABLES as ist
ON ist.TABLE_NAME=so.name where ist.TABLE_TYPE='BASE TABLE' AND
TABLE_CATALOG='DbName' order by so.modify_date desc;
this is help to get table modify with table name
Just for the forgetting-to-dispose problem, try the solution described in this blog post. Here's the essence:
public void Dispose ()
{
// Dispose logic here ...
// It's a bad error if someone forgets to call Dispose,
// so in Debug builds, we put a finalizer in to detect
// the error. If Dispose is called, we suppress the
// finalizer.
#if DEBUG
GC.SuppressFinalize(this);
#endif
}
#if DEBUG
~TimedLock()
{
// If this finalizer runs, someone somewhere failed to
// call Dispose, which means we've failed to leave
// a monitor!
System.Diagnostics.Debug.Fail("Undisposed lock");
}
#endif
[Swift Implementation]
Universal way of loading view from xib:
Example:
let myView = Bundle.loadView(fromNib: "MyView", withType: MyView.self)
Implementation:
extension Bundle {
static func loadView<T>(fromNib name: String, withType type: T.Type) -> T {
if let view = Bundle.main.loadNibNamed(name, owner: nil, options: nil)?.first as? T {
return view
}
fatalError("Could not load view with type " + String(describing: type))
}
}
As already stated, log4j.properties should be in a directory included in the classpath, I want to add that in a mavenized project a good place can be src/main/resources/log4j.properties
<meta name="format-detection" content="telephone=no">
. This metatag works in the default Safari browser on iOS devices and will only work for telephone numbers that are not wrapped in a telephone link so
1-800-123-4567
<a href="tel:18001234567">1-800-123-4567</a>
the first line will not be formatted as a link if you specify the metatag but the second line will because it's wrapped in a telephone anchor.
You can forego the metatag all-together and use a mixin such as
a[href^=tel]{
color:inherit;
text-decoration:inherit;
font-size:inherit;
font-style:inherit;
font-weight:inherit;
}
to maintain intended styling of your telephone numbers, but you must make sure you wrap them in a telephone anchor.
If you want to be extra cautious and protect against the event of a telephone number which is not properly formatted with a wrapping anchor tag you can drill through the DOM and adjust with this script. Adjust the replacement pattern as desired.
$('body').html($('body').html().replace(/^\D?(\d{3})\D?\D?(\d{3})\D?(\d{4})/g, '<a href="tel:+1$1$2$3">($1) $2-$3</a>'));
or even better without jQuery
document.body.innerHTML = document.body.innerHTML.replace(/^\D?(\d{3})\D?\D?(\d{3})\D?(\d{4})/g,'<a href="tel:+1$1$2$3">($1) $2-$3</a>');
To check if a specific tab page is the currently selected page of a tab control is easy; just use the SelectedTab property of the tab control:
if (tabControl1.SelectedTab == someTabPage)
{
// Do stuff here...
}
This is more useful if the code is executed based on some event other than the tab page being selected (in which case SelectedIndexChanged would be a better choice).
For example I have an application that uses a timer to regularly poll stuff over TCP/IP connection, but to avoid unnecessary TCP/IP traffic I only poll things that update GUI controls in the currently selected tab page.
# To read data from csv file
Dataset = pd.read_csv('Data.csv')
X = Dataset.iloc[:, :-1].values
# To calculate mean use imputer class
from sklearn.impute import SimpleImputer
imputer = SimpleImputer(missing_values=np.nan, strategy='mean')
imputer = imputer.fit(X[:, 1:3])
X[:, 1:3] = imputer.transform(X[:, 1:3])
I faced this issue few days back and this is the approach I followed and it works for me.
For me this was happening when i was trying to fetch data using axios or fetch libraries as i am under a corporate firewall, so we had certain particular certificates which node js certificate store was not able to point to.
So for my loclahost i followed this approach. I created a folder in my project and kept the entire chain of certificates in the folder and in my scripts for dev-server(package.json) i added this alongwith server script so that node js can reference the path.
"dev-server":set NODE_EXTRA_CA_CERTS=certificates/certs-bundle.crt
For my servers(different environments),I created a new environment variable as below and added it.I was using Openshift,but i suppose the concept will be same for others as well.
"name":NODE_EXTRA_CA_CERTS
"value":certificates/certs-bundle.crt
I didn't generate any certificate in my case as the entire chain of certificates was already available for me.
Just had this problem with visual studio being unable to find my tests, couldn't see the button to run them besides the method, and they weren't picked up by running all tests in the project.
Turns out my test class wasn't public! Making it public allowed VS to discover the tests.
This exception occurred in my application and was rather misleading.
It was thrown when I was calling an .aspx page Web Method using an ajax method call, passing a JSON array object. The Web Page method signature contained an array of a strongly-typed .NET object, OrderDetails. The Actual_Qty property was defined as an int, and the JSON object Actual_Qty property contained "4 " (extra space character). After removing the extra space, the conversion was made possible, the Web Page method was successfully reached by the ajax call.
A little bit of decorator treatment (very loosely inspired by the Maybe monad and lifting). You can safely remove Python 3.6 type annotations and use an older message formatting style.

You can also modify this solution to return something a bit more meaningful than None
from the except
part (or even make the solution generic, by specifying this return value in fallible
's arguments).
List<String> arrayList = new ArrayList<String>();
for (String s : arrayList) {
if(s.equals(value)){
//do something
}
}
or
for (int i = 0; i < arrayList.size(); i++) {
if(arrayList.get(i).equals(value)){
//do something
}
}
But be carefull ArrayList can hold null values. So comparation should be
value.equals(arrayList.get(i))
when you are sure that value is not null or you should check if given element is null.
You can use Array.prototype.reduce() and actual JavaScript Map instead just a JavaScript Object.
let keyValueObjArray = [
{ key: 'key1', val: 'val1' },
{ key: 'key2', val: 'val2' },
{ key: 'key3', val: 'val3' }
];
let keyValueMap = keyValueObjArray.reduce((mapAccumulator, obj) => {
// either one of the following syntax works
// mapAccumulator[obj.key] = obj.val;
mapAccumulator.set(obj.key, obj.val);
return mapAccumulator;
}, new Map());
console.log(keyValueMap);
console.log(keyValueMap.size);
What is different between Map And Object?
Previously, before Map was implemented in JavaScript, Object has been used as a Map because of their similar structure.
Depending on your use case, if u need to need to have ordered keys, need to access the size of the map or have frequent addition and removal from the map, a Map is preferable.
Quote from MDN document:
Objects are similar to Maps in that both let you set keys to values, retrieve those values, delete keys, and detect whether something is stored at a key. Because of this (and because there were no built-in alternatives), Objects have been used as Maps historically; however, there are important differences that make using a Map preferable in certain cases:
I believe to check if a key exists in a hash you just do
if (exists $strings{$string}) {
...
} else {
...
}
There 2 broad approaches to perform IP geolocation: one is to download a dataset, host it on your infrastructure and maintain it up-to-date. This requires time and effort, especially if you need to support a high number of requests. Another solution is to use an existing API service that manages all the work for you and more.
There exist many API Geolocation services: Maxmind, Ip2location, Ipstack, IpInfo, etc. Recently, the company I work for has switched to Ipregistry (https://ipregistry.co) and I was involved in the decision and implementation process. Here are some elements you should consider while looking for an IP geolocation API:
Here is an example to get IP geolocation information (but also threat and user agent data using one call):
$ip = $_SERVER['REMOTE_ADDR'];
$details = json_decode(file_get_contents("https://api.ipregistry.co/{$ip}?key=tryout"));
echo $details->location;
Note: I am not here to promote Ipregistry and say it's the best but I spent a long time analyzing existing solutions and their solution is really promising.
I have worked extensively in Excel and have found the following 3 points very useful
You can find this by using the following property on a sheet
ActiveSheet.UsedRange.Rows.Count
ActiveSheet.UsedRange.Columns.Count
If this range is more than the cells on which you have data, delete the rest of the rows/columns
You will be surprised to see the amount of space it can free
XLSM format is to make Excel compliant with Open XML, but there are very few instances when we actually use the XML format of Excel. This reduces size by almost 50% if not more
For example if you have to save the stock price for around 10 years, and you need to save Open, High, Low, Close for a stock, this would result in (252*10) * (4) cells being used
Instead, of using separate columns for Open,High,Low,Close save them in a single column with a field separator Open:High:Low:Close
You can easily write a function to extract info from the single column whenever you want to, but it will free up almost 2/3rd space that you are currently taking up
From http://us3.php.net/manual/en/function.parse-url.php#93983
for some odd reason, parse_url returns the host (ex. example.com) as the path when no scheme is provided in the input url. So I've written a quick function to get the real host:
function getHost($Address) {
$parseUrl = parse_url(trim($Address));
return trim($parseUrl['host'] ? $parseUrl['host'] : array_shift(explode('/', $parseUrl['path'], 2)));
}
getHost("example.com"); // Gives example.com
getHost("http://example.com"); // Gives example.com
getHost("www.example.com"); // Gives www.example.com
getHost("http://example.com/xyz"); // Gives example.com
OK, here is a step-by-step guide if you want to use COM.
using NsExcel = Microsoft.Office.Interop.Excel;
public void ListToExcel(List<string> list)
{
//start excel
NsExcel.ApplicationClass excapp = new Microsoft.Office.Interop.Excel.ApplicationClass();
//if you want to make excel visible
excapp.Visible = true;
//create a blank workbook
var workbook = excapp.Workbooks.Add(NsExcel.XlWBATemplate.xlWBATWorksheet);
//or open one - this is no pleasant, but yue're probably interested in the first parameter
string workbookPath = "C:\test.xls";
var workbook = excapp.Workbooks.Open(workbookPath,
0, false, 5, "", "", false, Excel.XlPlatform.xlWindows, "",
true, false, 0, true, false, false);
//Not done yet. You have to work on a specific sheet - note the cast
//You may not have any sheets at all. Then you have to add one with NsExcel.Worksheet.Add()
var sheet = (NsExcel.Worksheet)workbook.Sheets[1]; //indexing starts from 1
//do something usefull: you select now an individual cell
var range = sheet.get_Range("A1", "A1");
range.Value2 = "test"; //Value2 is not a typo
//now the list
string cellName;
int counter = 1;
foreach (var item in list)
{
cellName = "A" + counter.ToString();
var range = sheet.get_Range(cellName, cellName);
range.Value2 = item.ToString();
++counter;
}
//you've probably got the point by now, so a detailed explanation about workbook.SaveAs and workbook.Close is not necessary
//important: if you did not make excel visible terminating your application will terminate excel as well - I tested it
//but if you did it - to be honest - I don't know how to close the main excel window - maybee somewhere around excapp.Windows or excapp.ActiveWindow
}
To answer also to the comment by @MLT, there is an alternative to the standard cases
environment, not too sophisticated really, with both lines numbered. This code:
\documentclass{article}
\usepackage{amsmath}
\usepackage{cases}
\begin{document}
\begin{numcases}{f(x)=}
1, & if $x<0$\\
0, & otherwise
\end{numcases}
\end{document}
produces
Notice that here, math must be delimited by \(...\)
or $...$
, at least on the right of &
in each line (reference).
I had this exception in the case of a test for checking some actual accessed URLs by users.
And the URLs are sometime contains an illegal-character and hang by this error.
So I make a function to encode only the characters in the URL string like this.
String encodeIllegalChar(String uriStr,String enc)
throws URISyntaxException,UnsupportedEncodingException {
String _uriStr = uriStr;
int retryCount = 17;
while(true){
try{
new URI(_uriStr);
break;
}catch(URISyntaxException e){
String reason = e.getReason();
if(reason == null ||
!(
reason.contains("in path") ||
reason.contains("in query") ||
reason.contains("in fragment")
)
){
throw e;
}
if(0 > retryCount--){
throw e;
}
String input = e.getInput();
int idx = e.getIndex();
String illChar = String.valueOf(input.charAt(idx));
_uriStr = input.replace(illChar,URLEncoder.encode(illChar,enc));
}
}
return _uriStr;
}
test:
String q = "\\'|&`^\"<>)(}{][";
String url = "http://test.com/?q=" + q + "#" + q;
String eic = encodeIllegalChar(url,'UTF-8');
System.out.println(String.format(" original:%s",url));
System.out.println(String.format(" encoded:%s",eic));
System.out.println(String.format(" uri-obj:%s",new URI(eic)));
System.out.println(String.format("re-decoded:%s",URLDecoder.decode(eic)));
The code below does just that. The below is a working example to log into a game. I made a similar file to log in into Yahoo and a kurzweilai.net forum.
Just copy the login form from any webpage's source code. Add value= "your user name" and value = "your password". Normally the -input- elements in the source code do not have the value attribute, and sometime, you will see something like that: value=""
Save the file as a html on a local machine double click it, or make a bat/cmd file to launch and close them as required.
<!doctype html>
<!-- saved from url=(0014)about:internet -->

<input type="hidden" id="loginKid" name="kid" value=""/>
</form>
<script>document.loginForm.submit();</script>
</body></html>
Note that -script- is just -script-. I found there is no need to specify that is is JavaScript. It works anyway. I also found out that a bare-bones version that contains just two input filds: userName and password also work. But I left a hidded input field etc. just in case. Yahoo mail has a lot of hidden fields. Some are to do with password encryption, and it counts login attempts.
Security warnings and other staff, like Mark of the Web to make it work smoothly in IE are explained here:
For the beginners:
Null coalescing operator (??)
Everything is true except null
values and undefined (variable/array index/object attributes)
ex:
$array = [];
$object = new stdClass();
var_export (false ?? 'second'); # false
var_export (true ?? 'second'); # true
var_export (null ?? 'second'); # 'second'
var_export ('' ?? 'second'); # ""
var_export ('some text' ?? 'second'); # "some text"
var_export (0 ?? 'second'); # 0
var_export ($undefinedVarible ?? 'second'); # "second"
var_export ($array['undefined_index'] ?? 'second'); # "second"
var_export ($object->undefinedAttribute ?? 'second'); # "second"
this is basically check the variable(array index, object attribute.. etc) is exist and not null
. similar to isset
function
Ternary operator shorthand (?:)
every false things (false
,null
,0
,empty string) are come as false, but if it's a undefined it also come as false but Notice
will throw
ex
$array = [];
$object = new stdClass();
var_export (false ?: 'second'); # "second"
var_export (true ?: 'second'); # true
var_export (null ?: 'second'); # "second"
var_export ('' ?: 'second'); # "second"
var_export ('some text' ?? 'second'); # "some text"
var_export (0 ?: 'second'); # "second"
var_export ($undefinedVarible ?: 'second'); # "second" Notice: Undefined variable: ..
var_export ($array['undefined_index'] ?: 'second'); # "second" Notice: Undefined index: ..
var_export ($object->undefinedAttribute ?: 'second'); # "Notice: Undefined index: ..
Hope this helps
I found this maven
repo where you could download from directly a zip
file containing all the jars you need.
The solution I prefer is using Maven
, it is easy and you don't have to download each jar
alone. You can do it with the following steps:
Create an empty folder anywhere with any name you prefer, for example spring-source
Create a new file named pom.xml
Copy the xml below into this file
Open the spring-source
folder in your console
Run mvn install
After download finished, you'll find spring jars in /spring-source/target/dependencies
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Also, if you need to download any other spring project, just copy the dependency
configuration from its corresponding web page.
For example, if you want to download Spring Web Flow
jars, go to its web page, and add its dependency
configuration to the pom.xml
dependencies
, then run mvn install
again.

Use it after initialization code to get current date (in datepicker format):
$(".ui-datepicker-today").trigger("click");
I recently wrote a module called keysight that translates keypress
, keydown
, and keyup
events into characters and keys respectively.
Example:
element.addEventListener("keydown", function(event) {
var character = keysight(event).char
})
For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB.
To do this set org.gradle.jvmargs=-Xmx2048M
in the project gradle.properties.
If you are using Angular CLI: 7.3.3
What I did is, On my assets folder I put my fake json data then on my services I just did this.
const API_URL = './assets/data/db.json';
getAllPassengers(): Observable<PassengersInt[]> {
return this.http.get<PassengersInt[]>(API_URL);
}
$out.='<option value="'.$key.'">'.$value["name"];
me funciono con esta
"<a href='javascript:void(0)' onclick='cargar_datos_cliente(\"$row->DSC_EST\")' class='button micro asignar margin-none'>Editar</a>";
open file, save as .csv and then apply
df = pd.read_csv('apps.csv', sep='\t')
for any other format also, just change the sep tag
If after calling "csrutil disabled" still your command does not work, try with "sudo" in terminal, for example:
sudo mv geckodriver /usr/local/bin
And it should work.
AND, if you just want to get a count of all the rows in a table
$table_row_count = $this->db->count_all('table_name');
As @Lighthart as shown, yes it's possible, although it adds significant fat to the controller and isn't DRY.
You should really define your own query in the entity repository, it's simple and best practice.
use Doctrine\ORM\EntityRepository;
class UserRepository extends EntityRepository
{
public function findAll()
{
return $this->findBy(array(), array('username' => 'ASC'));
}
}
Then you must tell your entity to look for queries in the repository:
/**
* @ORM\Table(name="User")
* @ORM\Entity(repositoryClass="Acme\UserBundle\Entity\Repository\UserRepository")
*/
class User
{
...
}
Finally, in your controller:
$this->getDoctrine()->getRepository('AcmeBundle:User')->findAll();
java 1.6.0_21 or later, or so...
$ java -XX:+PrintFlagsFinal -version 2>&1 | grep MaxHeapSize
uintx MaxHeapSize := 12660904960 {product}
It looks like the min(1G) has been removed.
Or on Windows using findstr
C:\>java -XX:+PrintFlagsFinal -version 2>&1 | findstr MaxHeapSize
This works well for me:
WifiConfiguration apConfig = null;
Method method = wifimanager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, Boolean.TYPE);
method.invoke(wifimanager, apConfig, true);
In your service, add the following code.
@Override
public void onTaskRemoved(Intent rootIntent){
Intent restartServiceIntent = new Intent(getApplicationContext(), this.getClass());
restartServiceIntent.setPackage(getPackageName());
PendingIntent restartServicePendingIntent = PendingIntent.getService(getApplicationContext(), 1, restartServiceIntent, PendingIntent.FLAG_ONE_SHOT);
AlarmManager alarmService = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
alarmService.set(
AlarmManager.ELAPSED_REALTIME,
SystemClock.elapsedRealtime() + 1000,
restartServicePendingIntent);
super.onTaskRemoved(rootIntent);
}
I too was looking for a good way to do this, I found the best way was to set a transition on the "transform" property and then change the transform and then remove the transition.
I put it all together in a jQuery plugin
https://gist.github.com/dustinpoissant/8a4837c476e3939a5b3d1a2585e8d1b0
You would use the code like this:
$("#myElement").animateTransform("rotate(180deg)", 750, function(){
console.log("animation completed after 750ms");
});
I understand this issue is resolved but I happened to solve this same problem on my own.

# to which services and features are allowed and/or disabled in that
# directory (and its subdirectories).
#
# First, we configure the "default" to be a very restrictive set of
# features.
#
<Directory "/">
Options FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all # the cause of permission denied
</Directory>
Simply changing Deny from all
to Allow from all
should solve the permission problem.
Alternatively, a better approach would be to specify individual directory permissions on virtualhost configuration.
<VirtualHost *:80>
....
# Set access permission
<Directory "/path/to/docroot">
Allow from all
</Directory>
....
</VirtualHost>
As of Apache-2.4, however, access control is done using the new module mod_authz_host
(Upgrading to 2.4 from 2.2). Consequently, the new Require
directive should be used.
<VirtualHost *:80>
....
# Set access permission
<Directory "/path/to/docroot">
Require all granted
</Directory>
....
</VirtualHost>
Above solution was missing thing, and below code should work in every situation:
Windows Registry Editor Version 5.00
;
; Tell IE to open JSON documents in the browser.
; 25336920-03F9-11cf-8FD0-00AA00686F13 is the CLSID for the "Browse in place" .
;

Just save it file json.reg, and run to modify your registry.
Why not use the WordPress core function that's designed specifically for that purpose?
<?php plugin_dir_path( __FILE__ ); ?>
See Codex documentation here.
You also have
<?php plugin_dir_url( __FILE__ ); ?>
if what you're looking for is a URI as opposed to a server path.
See Codex documentation here.
IMO it's always best to use the highest-level method that's available in core, and this is it. It makes your code more future proof.

In the words of the master:
http://www.joelonsoftware.com/articles/Wrong.html
An interesting reading, as usual.
Extracts:
"Somebody, somewhere, read Simonyi’s paper, where he used the word “type,” and thought he meant type, like class, like in a type system, like the type checking that the compiler does. He did not. He explained very carefully exactly what he meant by the word “type,” but it didn’t help. The damage was done."
"But there’s still a tremendous amount of value to Apps Hungarian, in that it increases collocation in code, which makes the code easier to read, write, debug, and maintain, and, most importantly, it makes wrong code look wrong."
Make sure you have some time before reading Joel On Software. :)

Have you tried this code?
window.onbeforeunload = function (event) {
var message = 'Important: Please click on \'Save\' button to leave this page.';
if (typeof event == 'undefined') {
event = window.event;
}
if (event) {
event.returnValue = message;
}
return message;
};
$(function () {
$("a").not('#lnkLogOut').click(function () {

The second function is optional to avoid prompting while clicking on #lnkLogOut

This example reads 6 bytes into a byte array and writes it to another byte array. It does an XOR operation with the bytes so that the result written to the file is the same as the original starting values. The file is always 6 bytes in size, since it writes at position 0.
using System;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
static void Main()
{
byte[] b1 = { 1, 2, 4, 8, 16, 32 };
byte[] b2 = new byte[6];
byte[] b3 = new byte[6];
byte[] b4 = new byte[6];
FileStream f1;
f1 = new FileStream("test.txt", FileMode.Create, FileAccess.Write);
// write the byte array into a new file
f1.Write(b1, 0, 6);
f1.Close();
// read the byte array
f1 = new FileStream("test.txt", FileMode.Open, FileAccess.Read);
f1.Read(b2, 0, 6);
f1.Close();
// make changes to the byte array
for (int i = 1; i < b2.Length; i++)
{
b2[i] = (byte)(b2[i] ^ (byte)10); //xor 10
}
f1 = new FileStream("test.txt", FileMode.Open, FileAccess.Write);
// write the new byte array into the file
f1.Write(b2, 0, 6);
f1.Close();
f1 = new FileStream("test.txt", FileMode.Open, FileAccess.Read);
// read the byte array
f1.Read(b3, 0, 6);
f1.Close();
// make changes to the byte array
for (int i = 1; i < b3.Length; i++)
{
b4[i] = (byte)(b3[i] ^ (byte)10); //xor 10
}
f1 = new FileStream("test.txt", FileMode.Open, FileAccess.Write);
// b4 will have the same values as b1
f1.Write(b4, 0, 6);
f1.Close();
}
}

It has to do with BASE: the BASE jumper kind is always Basically Available (to new relationships), in a Soft state (none of his relationship last very long) and Eventually consistent (one day he will get married).
You need to call replace
on z
and not on str
, since you want to replace characters located in the string variable z
removeSpecialChars = z.replace("!@#$%^&*()[]{};:,./<>?\|`~-=_+", " ")
But this will not work, as replace looks for a substring, you will most likely need to use regular expression module re
with the sub
function:
import re
removeSpecialChars = re.sub("[!@#$%^&*()[]{};:,./<>?\|`~-=_+]", " ", z)
Don't forget the []
, which indicates that this is a set of characters to be replaced.
libfoo
depends on libbar
, then your linkage correctly puts libfoo
before libbar
.undefined reference to
something errors.#include
d and are in fact defined in the libraries that you are linking.Examples are in C. They could equally well be C++
my_lib.c
#include "my_lib.h"
#include <stdio.h>
void hw(void)
{
puts("Hello World");
}
my_lib.h
#ifndef MY_LIB_H
#define MT_LIB_H
extern void hw(void);
#endif
eg1.c
#include <my_lib.h>
int main()
{
hw();
return 0;
}
You build your static library:
$ gcc -c -o my_lib.o my_lib.c
$ ar rcs libmy_lib.a my_lib.o
You compile your program:
$ gcc -I. -c -o eg1.o eg1.c
You try to link it with libmy_lib.a
and fail:
$ gcc -o eg1 -L. -lmy_lib eg1.o
eg1.o: In function `main':
eg1.c:(.text+0x5): undefined reference to `hw'
collect2: error: ld returned 1 exit status
The same result if you compile and link in one step, like:
$ gcc -o eg1 -I. -L. -lmy_lib eg1.c
/tmp/ccQk1tvs.o: In function `main':
eg1.c:(.text+0x5): undefined reference to `hw'
collect2: error: ld returned 1 exit status
libz
eg2.c
#include <zlib.h>
#include <stdio.h>
int main()
{
printf("%s\n",zlibVersion());
return 0;
}
Compile your program:
$ gcc -c -o eg2.o eg2.c
Try to link your program with libz
and fail:
$ gcc -o eg2 -lz eg2.o
eg2.o: In function `main':
eg2.c:(.text+0x5): undefined reference to `zlibVersion'
collect2: error: ld returned 1 exit status
Same if you compile and link in one go:
$ gcc -o eg2 -I. -lz eg2.c
/tmp/ccxCiGn7.o: In function `main':
eg2.c:(.text+0x5): undefined reference to `zlibVersion'
collect2: error: ld returned 1 exit status
And a variation on example 2 involving pkg-config
:
$ gcc -o eg2 $(pkg-config --libs zlib) eg2.o
eg2.o: In function `main':
eg2.c:(.text+0x5): undefined reference to `zlibVersion'
In the sequence of object files and libraries you want to link to make your program, you are placing the libraries before the object files that refer to them. You need to place the libraries after the object files that refer to them.
Link example 1 correctly:
$ gcc -o eg1 eg1.o -L. -lmy_lib
Success:
$ ./eg1
Hello World
Link example 2 correctly:
$ gcc -o eg2 eg2.o -lz
Success:
$ ./eg2
1.2.8
Link the example 2 pkg-config
variation correctly:
$ gcc -o eg2 eg2.o $(pkg-config --libs zlib)
$ ./eg2
1.2.8
Reading is optional from here on.
By default, a linkage command generated by GCC, on your distro, consumes the files in the linkage from left to right in commandline sequence. When it finds that a file refers to something and does not contain a definition for it, to will search for a definition in files further to the right. If it eventually finds a definition, the reference is resolved. If any references remain unresolved at the end, the linkage fails: the linker does not search backwards.
First, example 1, with static library my_lib.a
A static library is an indexed archive of object files. When the linker
finds -lmy_lib
in the linkage sequence and figures out that this refers
to the static library ./libmy_lib.a
, it wants to know whether your program
needs any of the object files in libmy_lib.a
.
There is only object file in libmy_lib.a
, namely my_lib.o
, and there's only one thing defined
in my_lib.o
, namely the function hw
.
The linker will decide that your program needs my_lib.o
if and only if it already knows that
your program refers to hw
, in one or more of the object files it has already
added to the program, and that none of the object files it has already added
contains a definition for hw
.
If that is true, then the linker will extract a copy of my_lib.o
from the library and
add it to your program. Then, your program contains a definition for hw
, so
its references to hw
are resolved.
When you try to link the program like:
$ gcc -o eg1 -L. -lmy_lib eg1.o
the linker has not added eg1.o
to the program when it sees
-lmy_lib
. Because at that point, it has not seen eg1.o
.
Your program does not yet make any references to hw
: it
does not yet make any references at all, because all the references it makes
are in eg1.o
.
So the linker does not add my_lib.o
to the program and has no further
use for libmy_lib.a
.
Next, it finds eg1.o
, and adds it to be program. An object file in the
linkage sequence is always added to the program. Now, the program makes
a reference to hw
, and does not contain a definition of hw
; but
there is nothing left in the linkage sequence that could provide the missing
definition. The reference to hw
ends up unresolved, and the linkage fails.
Second, example 2, with shared library libz
A shared library isn't an archive of object files or anything like it. It's
much more like a program that doesn't have a main
function and
instead exposes multiple other symbols that it defines, so that other
programs can use them at runtime.
Many Linux distros today configure their GCC toolchain so that its language drivers (gcc
,g++
,gfortran
etc)
instruct the system linker (ld
) to link shared libraries on an as-needed basis.
You have got one of those distros.
This means that when the linker finds -lz
in the linkage sequence, and figures out that this refers
to the shared library (say) /usr/lib/x86_64-linux-gnu/libz.so
, it wants to know whether any references that it has added to your program that aren't yet defined have definitions that are exported by libz
If that is true, then the linker will not copy any chunks out of libz
and
add them to your program; instead, it will just doctor the code of your program
so that:-
At runtime, the system program loader will load a copy of libz
into the
same process as your program whenever it loads a copy of your program, to run it.
At runtime, whenever your program refers to something that is defined in
libz
, that reference uses the definition exported by the copy of libz
in
the same process.
Your program wants to refer to just one thing that has a definition exported by libz
,
namely the function zlibVersion
, which is referred to just once, in eg2.c
.
If the linker adds that reference to your program, and then finds the definition
exported by libz
, the reference is resolved
But when you try to link the program like:
gcc -o eg2 -lz eg2.o
the order of events is wrong in just the same way as with example 1.
At the point when the linker finds -lz
, there are no references to anything
in the program: they are all in eg2.o
, which has not yet been seen. So the
linker decides it has no use for libz
. When it reaches eg2.o
, adds it to the program,
and then has undefined reference to zlibVersion
, the linkage sequence is finished;
that reference is unresolved, and the linkage fails.
Lastly, the pkg-config
variation of example 2 has a now obvious explanation.
After shell-expansion:
gcc -o eg2 $(pkg-config --libs zlib) eg2.o
becomes:
gcc -o eg2 -lz eg2.o
which is just example 2 again.
The linkage:
gcc -o eg2 -lz eg2.o
works just fine for you!
(Or: That linkage worked fine for you on, say, Fedora 23, but fails on Ubuntu 16.04)
That's because the distro on which the linkage works is one of the ones that does not configure its GCC toolchain to link shared libraries as-needed.
Back in the day, it was normal for unix-like systems to link static and shared libraries by different rules. Static libraries in a linkage sequence were linked on the as-needed basis explained in example 1, but shared libraries were linked unconditionally.
This behaviour is economical at linktime because the linker doesn't have to ponder whether a shared library is needed by the program: if it's a shared library, link it. And most libraries in most linkages are shared libraries. But there are disadvantages too:-
It is uneconomical at runtime, because it can cause shared libraries to be loaded along with a program even if doesn't need them.
The different linkage rules for static and shared libraries can be confusing
to inexpert programmers, who may not know whether -lfoo
in their linkage
is going to resolve to /some/where/libfoo.a
or to /some/where/libfoo.so
,
and might not understand the difference between shared and static libraries
anyway.
This trade-off has led to the schismatic situation today. Some distros have changed their GCC linkage rules for shared libraries so that the as-needed principle applies for all libraries. Some distros have stuck with the old way.
If I just do:
$ gcc -o eg1 -I. -L. -lmy_lib eg1.c
surely gcc has to compile eg1.c
first, and then link the resulting
object file with libmy_lib.a
. So how can it not know that object file
is needed when it's doing the linking?
Because compiling and linking with a single command does not change the order of the linkage sequence.
When you run the command above, gcc
figures out that you want compilation +
linkage. So behind the scenes, it generates a compilation command, and runs
it, then generates a linkage command, and runs it, as if you had run the
two commands:
$ gcc -I. -c -o eg1.o eg1.c
$ gcc -o eg1 -L. -lmy_lib eg1.o
So the linkage fails just as it does if you do run those two commands. The
only difference you notice in the failure is that gcc has generated a
temporary object file in the compile + link case, because you're not telling it
to use eg1.o
. We see:
/tmp/ccQk1tvs.o: In function `main'
instead of:
eg1.o: In function `main':
The order in which interdependent linked libraries are specified is wrong
Putting interdependent libraries in the wrong order is just one way in which you can get files that need definitions of things coming later in the linkage than the files that provide the definitions. Putting libraries before the object files that refer to them is another way of making the same mistake.
You use Array.GetLength with the index of the dimension you wish to retrieve.
You can do it using write() :
#open file with *.html* extension to write html
file= open("my.html","w")
#write then close file
file.write(html)
file.close()
Perhaps not exactly what you asked, but I find this to be useful to put at the start of my programs:
import sys
if sys.version_info[0] < 3:
raise Exception("Python 3 or a more recent version is required.")
It's an unportable way to remove all data from the input buffer till the next newline. I've seen it used in cases like that:
char c;
char s[32];
puts("Type a char");
c=getchar();
fflush(stdin);
puts("Type a string");
fgets(s,32,stdin);
Without the fflush()
, if you type a character, say "a", and the hit enter, the input buffer contains "a\n", the getchar()
peeks the "a", but the "\n" remains in the buffer, so the next fgets()
will find it and return an empty string without even waiting for user input.
However, note that this use of fflush()
is unportable. I've tested right now on a Linux machine, and it does not work, for example.
In your example, the compiler has no way of knowing what type should TModel
be. You could do something close to what you are probably trying to do with an extension method.
static class ModelExtensions
{
public static IDictionary<string, object> GetHtmlAttributes<TModel, TProperty>
(this TModel model, Expression<Func<TModel, TProperty>> propertyExpression)
{
return new Dictionary<string, object>();
}
}
But you wouldn't be able to have anything similar to virtual
, I think.
EDIT:
Actually, you can do virtual
, using self-referential generics:
class ModelBase<TModel>
{
public virtual IDictionary<string, object> GetHtmlAttributes<TProperty>
(Expression<Func<TModel, TProperty>> propertyExpression)
{
return new Dictionary<string, object>();
}
}
class FooModel : ModelBase<FooModel>
{
public override IDictionary<string, object> GetHtmlAttributes<TProperty>
(Expression<Func<FooModel, TProperty>> propertyExpression)
{
return new Dictionary<string, object> { { "foo", "bar" } };
}
}
It's the ASCII keycode in hexadecimal for a comma (,
).
You should use your language's URL encoding methods when placing strings in URLs.
You can see a handy list of characters with man ascii
. It has this compact diagram available for mapping hexadecimal codes to the character:
2 3 4 5 6 7
-------------
0: 0 @ P ` p
1: ! 1 A Q a q
2: " 2 B R b r
3: # 3 C S c s
4: $ 4 D T d t
5: % 5 E U e u
6: & 6 F V f v
7: ' 7 G W g w
8: ( 8 H X h x
9: ) 9 I Y i y
A: * : J Z j z
B: + ; K [ k {
C: , < L \ l |
D: - = M ] m }
E: . > N ^ n ~
F: / ? O _ o DEL
You can also quickly check a character's hexadecimal equivalent with:
$ echo -n , | xxd -p
2c
If you don't want to show controls then try this code

If someone need the same in Xamarin (Xamarin.ios / Monotouch), this worked for me:
var myDelegate = UIApplication.SharedApplication.Delegate as AppDelegate;
(Require using UIKit;)
CPUnit (http://cpunit.sourceforge.net) is a framework that is similar to Google Test, but which relies on less macos (asserts are functions), and where the macros are prefixed to avoid the usual macro pitfall. Tests look like:
#include <cpunit>
namespace MyAssetTest {
using namespace cpunit;
CPUNIT_FUNC(MyAssetTest, test_stuff) {
int some_value = 42;
assert_equals("Wrong value!", 666, some_value);
}
// Fixtures go as follows:
CPUNIT_SET_UP(MyAssetTest) {
// Setting up suite here...
// And the same goes for tear-down.
}
}
They auto-register, so you need not more than this. Then it is just compile and run. I find using this framework very much like using JUnit, for those who have had to spend some time programming Java. Very nice!

The most complete answer I have found is here: http://blog.kikicode.com/2013/10/installing-android-adb-driver-in.html
I'm copying the complete answer below.
For some reason I just couldn't get my machine to recognize Xperia J in Windows 8.1 64-bit. Even after installing latest Sony PC Companion (2.10.174). Device Manager kept showing yellow exclamation mark to an 'Android'.
Here's the solution, but I don't promise it will work on your device!
Open Device Manager, right-click that Android with yellow exclamation mark and click Properties. Go to Details tab. In Property, select Hardware Ids. Right-click the value and click Copy. Paste the value somewhere.
Run Android SDK Manager. Expand Extras, tick Google USB Driver, click Install packages. After installation, look for the driver location by hovering mouse over Google USB Driver. The location will appear in the tooltip.
Go to the usb driver location, for example in the above picture it is c:\Android\android-studio\sdk\extras\google\usb_driver Make a backup copy of android_winusb.inf Open android_winusb.inf with a text editor. Notepad is fine but Notepad++ is better, it will syntax highlight the inf file! Look for [Google.NTx86], and insert a line with your device's hardware ID that you copied above, for example
[Google.NTx86]
; ... other existing lines
;SONY Sony Xperia J
%CompositeAdbInterface% = USB_Install, USB\VID_0FCE&PID_6188&MI_01
Look for [Google.NTamd86], and insert the same lines, for example:
[Google.NTamd64]
; ... other existing lines
;SONY Sony Xperia J
%CompositeAdbInterface% = USB_Install, USB\VID_0FCE&PID_6188&MI_01
Save the file.
Run Command Prompt as an administrator Paste and run the following commands:
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING ON
Restart Windows.
Open Device Manager, right-click that Android with yellow exclamation mark and click Update Driver Software. Click Browse my computer for driver software. Enter or browse to the folder containing android_winusb.inf, eg: C:\Android\android-studio\sdk\extras\google\usb_driver Click Next. The driver will install. Run adb devices to confirm your device is working fine.
Run Command Prompt as an administrator Paste and run the following commands:
bcdedit -set loadoptions ENABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING OFF
Restart Windows. Run adb devices to reconfirm!
One of the reason may be improper date/time of your PC.
In Ubuntu PC to check the date and time using:
date
Example, One of the ways to update date and time is:
date -s "23 MAR 2017 17:06:00"
dict.iteritems
is gone in Python3.x So use iter(dict.items())
to get the same output and memory alocation
The above are all excellent answers. I just wanted to add that when there are multiple characters to check against, an if-else might turn out better since you could instead write the following.
// switch on vowels, digits, punctuation, or consonants
char c; // assign some character to 'c'
if ("aeiouAEIOU".indexOf(c) != -1) {
// handle vowel case
} else if ("!@#$%,.".indexOf(c) != -1) {
// handle punctuation case
} else if ("0123456789".indexOf(c) != -1) {
// handle digit case
} else {
// handle consonant case, assuming other characters are not possible
}
Of course, if this gets any more complicated, I'd recommend a regex matcher.
For anyone having issues with this on https://forge.laravel.com, I managed to get this to work using a compilation of SO answers;

__DIR__
From the manual:
The directory of the file. If used inside an include, the directory of the included file is returned. This is equivalent to dirname(__FILE__)
. This directory name does not have a trailing slash unless it is the root directory.
__FILE__
always contains an absolute path with symlinks resolved whereas in older versions (than 4.0.2) it contained relative path under some circumstances.
Note: __DIR__
was added in PHP 5.3.0.
Instead of having the additional ping -n 2 localhost
at the end of the loop, you can just add the character R before !data!
since the only possibilities are Reply or Request. The first character is consumed from the pause>nul
. So instead of having the following expression:
ping localhost -t -l 4|cmd /q /v /c "(pause&pause)>nul & for /l %%a in () do (set /p data=&echo(!date! !time! !data!)&ping -n 2 localhost>nul"
You can use this expression:
ping localhost -t -l 4|cmd /q /v /c "(pause&pause)>nul & for /l %%a in () do (set /p data=&echo(!date! !time! R!data!)&pause>nul"
Which produces the same output eg.:

The canonical way to do this with Rails 3:
Foo.includes(:bar).where("bars.id IS NOT NULL")
ActiveRecord 4.0 and above adds where.not
so you can do this:
Foo.includes(:bar).where.not('bars.id' => nil)
Foo.includes(:bar).where.not(bars: { id: nil })
When working with scopes between tables, I prefer to leverage merge
so that I can use existing scopes more easily.
Foo.includes(:bar).merge(Bar.where.not(id: nil))
Also, since includes
does not always choose a join strategy, you should use references
here as well, otherwise you may end up with invalid SQL.
Foo.includes(:bar)
.references(:bar)
.merge(Bar.where.not(id: nil))

Me, I'd do it something like this:
HTML:
onclick="myfunction({path:'/myController/myAction', ok:myfunctionOnOk, okArgs:['/myController2/myAction2','myParameter2'], cancel:myfunctionOnCancel, cancelArgs:['/myController3/myAction3','myParameter3']);"
JS:
function myfunction(params)
{
var path = params.path;
/* do stuff */
// on ok condition
params.ok(params.okArgs);
// on cancel condition
params.cancel(params.cancelArgs);
}
But then I'd also probable be binding a closure to a custom subscribed event. You need to add some detail to the question really, but being first-class functions are easily passable and getting params to them can be done any number of ways. I would avoid passing them as string labels though, the indirection is error prone.
From the documentation page
To set the page type pass the value in constructor

To set font size
setFontSize(size)
Sets font size for upcoming text elements.
Parameters:
{Number} size Font size in points.
While there might be a way I would tend to keep that kind of logic out of the Model. I agree that you shouldn't put that in the view (keep it skinny) but unless the model is returning a url as a piece of data to the controller, the routing stuff should be in the controller.
@Override
public void onBackPressed() {
new AlertDialog.Builder(this)
.setMessage("Are you sure you want to exit?")
.setCancelable(false)
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
ExampleActivity.super.onBackPressed();
}
})
.setNegativeButton("No", null)
.show();
}

null
is null
. false
is false
. Sad but true.
there's not much consistency in PHP (though it is improving on latest releases, there's too much backward compatibility). Despite the design wishing some consistency (outlined in the selected answer here), it all get confusing when you consider method returns that use false
/null
in not-so-easy to reason ways.
You will often see null being used when they are already using false for something. e.g. filter_input(). They return false if the variable fails the filter, and null if the variable does not exists (does not existing means it also failed the filter?)
Methods returning false/null/string/etc interchangeably is a hack when the author care about the type of failure, for example, with filter_input()
you can check for ===false
or ===null
if you care why the validation failed. But if you don't it might be a pitfall as one might forget to add the check for ===null
if they only remembered to write the test case for ===false
. And most php unit test/coverage tools will not call your attention for the missing, untested code path!
Lastly, here's some fun with type juggling. not even including arrays or objects.

The solution for the error is to add this line at the top of the code:
process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";
You can go to the browser in Iphone/Ipad and type the URl where the IPA has been uploaded and can directly download it to your Iphone or Ipad and install and run it.... simple and sweet ;)
cs95 shows that Pandas vectorization far outperforms other Pandas methods for computing stuff with dataframes.
I wanted to add that if you first convert the dataframe to a NumPy array and then use vectorization, it's even faster than Pandas dataframe vectorization, (and that includes the time to turn it back into a dataframe series).
If you add the following functions to cs95's benchmark code, this becomes pretty evident:
def np_vectorization(df):
np_arr = df.to_numpy()
return pd.Series(np_arr[:,0] + np_arr[:,1], index=df.index)
def just_np_vectorization(df):
np_arr = df.to_numpy()
return np_arr[:,0] + np_arr[:,1]

You have no control over the user moving the orientation however you can at least message them. This example will hide the wrapper if in portrait mode and show the warning message and then hide the warning message in landscape mode and show the portrait.
I don't think this answer is any better than @Golmaal , only a compliment to it. If you like this answer, make sure to give @Golmaal the credit.
Update
I've been working with Cordova a lot recently and it turns out you CAN control it when you have access to the native features.
Another Update
So after releasing Cordova it is really terrible in the end. It is better to use something like React Native if you want JavaScript. It is really amazing and I know it isn't pure web but the pure web experience on mobile kind of failed.
Base package
Using the function strftime
passing the argument %V
to obtain the week of the year as decimal number (01–53) as defined in ISO 8601. (More details in the documentarion: ?strftime)
strftime(c("2014-03-16", "2014-03-17","2014-03-18", "2014-01-01"), format = "%V")
Output:
[1] "11" "12" "12" "01"
This cross-browser lib seems safer - just zoom and moz-transform won't cover as many browsers as jquery.transform2d's scale().
http://louisremi.github.io/jquery.transform.js/
For example
$('#div').css({ transform: 'scale(.5)' });
OK - I see people are voting this down without an explanation. The other answer here won't work in old Safari (people running Tiger), and it won't work consistently in some older browsers - that is, it does scale things but it does so in a way that's either very pixellated or shifts the position of the element in a way that doesn't match other browsers.

Or just look at this question, which this one is likely just a dupe of:
Create Schema :
IF (NOT EXISTS (SELECT * FROM sys.schemas WHERE name = 'exe'))
BEGIN
EXEC ('CREATE SCHEMA [exe] AUTHORIZATION [dbo]')
END
ALTER Schema :

comes with the JDK. If you are using cygwin then this is probably on your path already. Otherwise, you might dig around in your JDK's bin folder.
You'll probably need to use cygwin anyways for the shell pipes (|

I delete the Bundle identifier in the https://developer.apple.com/account/resources/identifiers/list, then it works.
just put this method in your forms then it will handle double-click or more clicks in once. once request send it will not allow sending again and again request.
<script type="text/javascript">
$(document).ready(function(){
$("form").submit(function() {
$(this).submit(function() {
return false;
});
return true;
});
});
</script>
it will help you for sure.
