In my case the problem was that my application had literally no information filled in the App Store Connect
the approach you took is good. Just Implementation may need to be better. For instance ReturningValues should be well defined and Its better if you can make ReturningValues as immutable.
// this approach is better
public static ReturningValues myMethod() {
ReturningValues rv = new ReturningValues("value", 12);
return rv;
}
public final class ReturningValues {
private final String value;
private final int index;
public ReturningValues(String value, int index) {
this.value = value;
this.index = index;
}
}
Or if you have lots of key value pairs you can use HashMap then
public static Map<String,Object> myMethod() {
Map<String,Object> map = new HashMap<String,Object>();
map.put(VALUE, "value");
map.put(INDEX, 12);
return Collections.unmodifiableMap(map); // try to use this
}
Use the where
command. The first result in the list is the one that will execute.
C:\> where notepad C:\Windows\System32\notepad.exe C:\Windows\notepad.exe
According to this blog post, where.exe
is included with Windows Server 2003 and later, so this should just work with Vista, Win 7, et al.
On Linux, the equivalent is the which
command, e.g. which ssh
.
I tried this to easily use another port:
PORT=80 npm run dev
The simplest method to bring a resource from the classpath in the resources directory parsed into a String is the following one liner.
As a String(Using Spring Libraries):
String resource = StreamUtils.copyToString(
new ClassPathResource("resource.json").getInputStream(), defaultCharset());
This method uses the StreamUtils utility and streams the file as an input stream into a String in a concise compact way.
If you want the file as a byte array you can use basic Java File I/O libraries:
As a byte array(Using Java Libraries):
byte[] resource = Files.readAllBytes(Paths.get("/src/test/resources/resource.json"));
I also ran into the error message invalid command 'bdist_wheel'
It turns out the package setup.py used distutils rather than setuptools. Changing it as follows enabled me to build the wheel.
#from distutils.core import setup
from setuptools import setup
For your design, it is common practice to use divs rather than a table. This way, your layout will be more maintainable and changeable through proper styling. It does take some getting used to, but it will help you a ton in the long run and you will learn a lot about how styling works. However, I will provide you with a solution to the problem at hand.
In your stylesheets you have margins and padding set to 0 pixels. This overrides your align="center"
attribute. I would recommend taking these settings out of your CSS as you don't normally want all of your elements to be affected in this manner. If you already know what's going on in the CSS, and you want to keep it that way, then you have to apply a style to your table to override the previous sets. You could either give the table a class
or you can put the style inline with the HTML. Here are the two options:
With a class:
<table class="centerTable"></table>
In your style.css file you would have something like this:
.centerTable { margin: 0px auto; }
Inline with your HTML:
<table style="margin: 0px auto;"></table>
If you decide to wipe out the margins and padding being set to 0px, then you can keep align="center"
on your <td>
tags for whatever column you wish to align.
You might find it better to use a 3rd party program to enter the queries into Access such as WinSQL I think from memory WinSQL supports multiple queries via it's batch feature.
I ultimately found it easier to just write a program in perl to do bulk INSERTS into an Access via ODBC. You could use vbscript or any language that supports ODBC though.
You can then do anything you like and have your own complicated logic to handle the importing.
java.util.Date date;
Timestamp timestamp = resultSet.getTimestamp(i);
if (timestamp != null)
date = new java.util.Date(timestamp.getTime()));
Then format it the way you like.
Here's a way that will work:
export function getFunctionCallerName (){
// gets the text between whitespace for second part of stacktrace
return (new Error()).stack.match(/at (\S+)/g)[1].slice(3);
}
Then in your tests:
import { expect } from 'chai';
import { getFunctionCallerName } from '../../../lib/util/functions';
describe('Testing caller name', () => {
it('should return the name of the function', () => {
function getThisName(){
return getFunctionCallerName();
}
const functionName = getThisName();
expect(functionName).to.equal('getThisName');
});
it('should work with an anonymous function', () => {
const anonymousFn = function (){
return getFunctionCallerName();
};
const functionName = anonymousFn();
expect(functionName).to.equal('anonymousFn');
});
it('should work with an anonymous function', () => {
const fnName = (function (){
return getFunctionCallerName();
})();
expect(/\/util\/functions\.js/.test(fnName)).to.eql(true);
});
});
Note that the third test will only work if the test is located in /util/functions
Add the --fields
parameter as comma separated field names enclosed in double inverted quotes:
--fields "<FIELD 1>,<FIELD 2>..."
This is complete example:
mongoexport --host Cluster0-shard-0/shard1URL.mongodb.net:27017,shard2URL.mongodb.net:27017,shard3URL.mongodb.net:27017 --ssl --username <USERNAME> --password <PASSWORD> --authenticationDatabase admin --db <DB NAME> --collection <COLLECTION NAME> --type <OUTPUT FILE TYPE> --out <OUTPUT FILE NAME> --fields "<FIELD 1>,<FIELD 2>..."
git rebase -i HEAD~<quantity of your commits>
(i.e. git rebase -i HEAD~5
)txt
file change pick
keyword to squash
for all commits, except first commit (which is on the top). For top one change it to reword
(which means you will provide a new comment for this commit in the next step) and click SAVE! If in vim, press esc
then save by entering wq!
and press enter.Done
I notice that your URL has spaces in it. I think that usually is a bad thing. Try encoding the URL with
$my_url = urlencode("my url");
and then calling
file_get_contents($my_url);
and see if you have better luck.
(It's been a while since I did this stuff. Please don't blindly assume that all the details below are correct. But I hope I'm not too embarrassingly wrong. :))
As the previous answer stated, the Minecraft client (as of 1.3.1) supports SRV record lookup using the service name _minecraft
and the protocol name _tcp
, which means that if your zone file looks like this...
arboristal.com. 86400 IN A <your IP address>
_minecraft._tcp.arboristal.com. 86400 IN SRV 10 20 25565 arboristal.com.
_minecraft._tcp.arboristal.com. 86400 IN SRV 10 40 25566 arboristal.com.
_minecraft._tcp.arboristal.com. 86400 IN SRV 10 40 25567 arboristal.com.
...then Minecraft clients who perform SRV record lookup as hinted in the changelog will use ports 25566 and 25567 with preference (40% of the time each) over port 25565 (20% of the time). We can assume that Minecraft clients who do not find and respect these SRV records will use port 25565 as usual.
However, I would argue that it would actually be more "clean and professional" to do it using a load balancer such as Nginx. (I pick Nginx just because I've used it before. I'm not claiming it's uniquely suited to this task. It might even be a bad choice for some reason.) Then you don't have to mess with your DNS, and you can use the same approach to load-balance any service, not just ones like Minecraft which happen to have done the hard client-side work to look up and respect SRV records. To do it the Nginx way, you'd run Nginx on the arboristal.com
machine with something like the following in /etc/nginx/sites-enabled/arboristal.com
:
upstream minecraft_servers {
ip_hash;
server 127.0.0.1:25566 weight=1;
server 127.0.0.1:25567 weight=1;
server 127.0.0.1:25568 weight=1;
}
server {
listen 25565;
proxy_pass minecraft_servers;
}
Here we are controlling the load-balancing ourselves on the server side (via Nginx), so we no longer need to worry that badly behaved clients might prefer port 25565 to the other two ports. In fact, now all clients will talk to arboristal.com:25565
! But the listener on that port is no longer a Minecraft server; it's Nginx, secretly proxying all the traffic onto three other ports on the same machine.
We load-balance based on a hash of the client's IP address (ip_hash
), so that if a client disconnects and then reconnects later, there's a good chance that it'll get reconnected to the same Minecraft server it had before. (I don't know how much this matters to Minecraft, or how SRV-enabled clients are programmed to deal with this aspect.)
Notice that we used to run a Minecraft server on port 25565; I've moved it to port 25568 so that we can use port 25565 for the load-balancer.
A possible disadvantage of the Nginx method is that it makes Nginx a bottleneck in your system. If Nginx goes down, then all three servers become unreachable. If some part of your system can't keep up with the volume of traffic on that single port, 25565, all three servers become flaky. And not to mention, Nginx is a big new dependency in your ecosystem. Maybe you don't want to introduce yet another massive piece of software with a complicated config language and a huge attack surface. I can respect that.
A possible advantage of the Nginx method is... that it makes Nginx a bottleneck in your system! You can apply global policies via Nginx, such as rejecting packets above a certain size, or responding with a static web page to HTTP connections on port 80. You can also firewall off ports 25566, 25567, and 25568 from the Internet, since now they should be talked to only by Nginx over the loopback interface. This reduces your attack surface somewhat.
Nginx also makes it easier to add new Minecraft servers to your backend; now you can just add a server
line to your config and service nginx reload
. Using the old port-based approach, you'd have to add a new SRV record with your DNS provider (and it could take up to 86400
seconds for clients to notice the change) and then also remember to edit your firewall (e.g. /etc/iptables.rules
) to permit external traffic over that new port.
Nginx also frees you from having to think about DNS TTLs when making ops changes. Suppose you decide to split up your three Minecraft servers onto three different physical machines with different IP addresses. Using Nginx, you can do that completely via config changes to your server
lines, and you can keep those new machines inside your firewall (connected only to Nginx over a private interface), and the changes will take effect immediately, by definition. Whereas, using SRV records, you'll have to rewrite your zone file to something like this...
arboristal.com. 86400 IN CNAME mc1.arboristal.com.
mc1.arboristal.com. 86400 IN A <a new machine's IP address>
mc2.arboristal.com. 86400 IN A <a new machine's IP address>
mc3.arboristal.com. 86400 IN A <a new machine's IP address>
_minecraft._tcp.arboristal.com. 86400 IN SRV 10 20 25565 mc1.arboristal.com.
_minecraft._tcp.arboristal.com. 86400 IN SRV 10 40 25565 mc2.arboristal.com.
_minecraft._tcp.arboristal.com. 86400 IN SRV 10 40 25565 mc3.arboristal.com.
...and you'll have to leave all three new machines poking outside your firewall so that they can receive connections from the Internet. And you'll have to wait up to 86400
seconds for your clients to notice the change, which could affect the complexity of your rollout plan. And if you were running any other services (such as an HTTP server) on arboristal.com
, now you have to move them to the mc1.arboristal.com
machine because of how I did that CNAME. I did that only for the benefit of those hypothetical Minecraft clients who don't respect SRV records and will still be trying to connect to arboristal.com:25565
.
So, I think both ways (SRV records and Nginx load-balancing) are reasonable, and your choice will depend on your personal preferences. I caricature the options as:
arboristal.com
taking over the world, or at least moving to a bigger machine someday. I'm not scared of learning a new tool. What's a zone file?"You can adjust the plot margins with plot.margin
in theme()
and then move your axis labels and title with the vjust
argument of element_text()
. For example :
library(ggplot2)
library(grid)
qplot(rnorm(100)) +
ggtitle("Title") +
theme(axis.title.x=element_text(vjust=-2)) +
theme(axis.title.y=element_text(angle=90, vjust=-0.5)) +
theme(plot.title=element_text(size=15, vjust=3)) +
theme(plot.margin = unit(c(1,1,1,1), "cm"))
will give you something like this :
If you want more informations about the different theme()
parameters and their arguments, you can just enter ?theme
at the R prompt.
To flip bits (i.e. 1's complement/invert) you can do the following:
Since value ExORed with all 1s results into inversion, for a given bit width you can use ExOR to invert them.
In Binary
a=1010 --> this is 0xA or decimal 10
then
c = 1111 ^ a = 0101 --> this is 0xF or decimal 15
-----------------
In Python
a=10
b=15
c = a ^ b --> 0101
print(bin(c)) # gives '0b101'
An algorithm is a self-contained step-by-step set of operations to be performed 4, typically interpreted as a finite sequence of (computer or human) instructions to determine a solution to a problem such as: is there a path from A to B, or what is the smallest path between A and B. In the latter case, you could also be satisfied with a 'reasonably close' alternative solution.
There are certain categories of algorithms, of which the heuristic algorithm is one. Depending on the (proven) properties of the algorithm in this case, it falls into one of these three categories (note 1):
Notice that an approximation algorithm is also a heuristic, but with the stronger property that there is a proven bound to the solution (value) it outputs.
For some problems, noone has ever found an 'efficient' algorithm to compute the optimal solutions (note 2). One of those problems is the well-known Traveling Salesman Problem. Christophides' algorithm for the Traveling Salesman Problem, for example, used to be called a heuristic, as it was not proven that it was within 50% of the optimal solution. Since it has been proven, however, Christophides' algorithm is more accurately referred to as an approximation algorithm.
Due to restrictions on what computers can do, it is not always possible to efficiently find the best solution possible. If there is enough structure in a problem, there may be an efficient way to traverse the solution space, even though the solution space is huge (i.e. in the shortest path problem).
Heuristics are typically applied to improve the running time of algorithms, by adding 'expert information' or 'educated guesses' to guide the search direction. In practice, a heuristic may also be a sub-routine for an optimal algorithm, to determine where to look first.
(note 1): Additionally, algorithms are characterised by whether they include random or non-deterministic elements. An algorithm that always executes the same way and produces the same answer, is called deterministic.
(note 2): This is called the P vs NP problem, and problems that are classified as NP-complete and NP-hard are unlikely to have an 'efficient' algorithm. Note; as @Kriss mentioned in the comments, there are even 'worse' types of problems, which may need exponential time or space to compute.
There are several answers that answer part of the question. I deemed them less complete and not accurate enough, and decided not to edit the accepted answer made by @Kriss
Slight change to make it work on my region, Europe (. as thousands separator, comma as decimal separator):

If you're using the Prototype JavaScript framework then you can use the focusFirstElement method:

I strongly favour minimal file headers, by which I mean just:
#!
line) if this is an executable script import os # standard library
import sys
import requests # 3rd party packages
from mypackage import ( # local source
mymodule,
myothermodule,
)
ie. three groups of imports, with a single blank line between them. Within each group, imports are sorted. The final group, imports from local source, can either be absolute imports as shown, or explicit relative imports.
Everything else is a waste of time, visual space, and is actively misleading.
If you have legal disclaimers or licencing info, it goes into a separate file. It does not need to infect every source code file. Your copyright should be part of this. People should be able to find it in your LICENSE
file, not random source code.
Metadata such as authorship and dates is already maintained by your source control. There is no need to add a less-detailed, erroneous, and out-of-date version of the same info in the file itself.
I don't believe there is any other data that everyone needs to put into all their source files. You may have some particular requirement to do so, but such things apply, by definition, only to you. They have no place in “general headers recommended for everyone”.
If you want to get Syntax Error with line number, use this

This is probably the most elegant way to do it.
Right in the PDO constructor call, but avoiding the buggy charset option (as mentioned above):
$connect = new PDO(
"mysql:host=$host;dbname=$db",
$user,
$pass,

PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"
)
);
Works great for me.
Use the collapse

Method call setSelectedIndex("item_value");
doesn't work because setSelectedIndex
use sequential index.
Since you don't want stretching (all of the other answers ignore that) you can simply set max-width and max-height like in my jsFiddle edit.
#container img {
max-height: 250px;
max-width: 250px;
}
See my example with an image that isn't a square, it doesn't stretch
There are various causes of segmentation faults, but fundamentally, you are accessing memory incorrectly. This could be caused by dereferencing a null pointer, or by trying to modify readonly memory, or by using a pointer to somewhere that is not mapped into the memory space of your process (that probably means you are trying to use a number as a pointer, or you incremented a pointer too far). On some machines, it is possible for a misaligned access via a pointer to cause the problem too - if you have an odd address and try to read an even number of bytes from it, for example (that can generate SIGBUS, instead).
Your box doesn't have a size. If you set the width and height, it works just fine:

I used the properties plugin to solve this.
Properties are defined in the pom, and written out to a my.properties file, where they can then be accessed from your Java code.
In my case it is test code that needs to access this properties file, so in the pom the properties file is written to maven's testOutputDirectory:
<configuration>
<outputFile>${project.build.testOutputDirectory}/my.properties</outputFile>
</configuration>
Use outputDirectory if you want properties to be accessible by your app code:
<configuration>
<outputFile>${project.build.outputDirectory}/my.properties</outputFile>
</configuration>
For those looking for a fuller example (it took me a bit of fiddling to get this working as I didn't understand how naming of properties tags affects ability to retrieve them elsewhere in the pom file), my pom looks as follows:
<dependencies>
<dependency>
...
</dependency>
</dependencies>
<properties>
<app.env>${app.env}</app.env>
<app.port>${app.port}</app.port>
<app.domain>${app.domain}</app.domain>
</properties>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.20</version>
</plugin>

</goals>
<configuration>
<outputFile>${project.build.testOutputDirectory}/my.properties</outputFile>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
And on the command line:
mvn clean test -Dapp.env=LOCAL -Dapp.domain=localhost -Dapp.port=9901
So these properties can be accessed from the Java code:
java.io.InputStream inputStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("my.properties");
java.util.Properties properties = new Properties();
properties.load(inputStream);
appPort = properties.getProperty("app.port");
appDomain = properties.getProperty("app.domain");

The accepted answer above did not work for me, because it ordered the weeks by alphabetical order, not chronological order:
2012/1
2012/10
2012/11
...
2012/19
2012/2
Here's my solution to count and group by week:
SELECT CONCAT(YEAR(date), '/', WEEK(date)) AS week_name,
YEAR(date), WEEK(date), COUNT(*)
FROM column_name
GROUP BY week_name
ORDER BY YEAR(DATE) ASC, WEEK(date) ASC
Generates:
YEAR/WEEK YEAR WEEK COUNT
2011/51 2011 51 15
2011/52 2011 52 14
2012/1 2012 1 20
2012/2 2012 2 14
2012/3 2012 3 19
2012/4 2012 4 19
For example, you might want to make sure that when you free the memory of something you set the pointer to null afterwards.
void safeFree(void** memory) {
if (*memory) {
free(*memory);
*memory = NULL;

When you call this function you'd call it with the address of a pointer
void* myMemory = someCrazyFunctionThatAllocatesMemory();
safeFree(&myMemory);
Now myMemory
is set to NULL and any attempt to reuse it will be very obviously wrong.
Actually there is no c3 in the sample code in the original question. So the if would be more properly
if (c1 && c2) {
//sequence 1
} else if (!c1 && !c2) {
// sequence 3
}
You can use grep to get the byte-offset of the matching part of a string:
echo $str | grep -b -o str
As per your example:
[user@host ~]$ echo "The cat sat on the mat" | grep -b -o cat
4:cat
you can pipe that to awk if you just want the first part
echo $str | grep -b -o str | awk 'BEGIN {FS=":"}{print $1}'
Before you extract values from $_POST
, you should check if they exist. You could use the isset
function for this (http://php.net/manual/en/function.isset.php)
I think this should do it..

First, convert the timespan to a string, then to DateTime, then back to a string:
Convert.ToDateTime(timespan.SelectedTime.ToString()).ToShortTimeString();
First make sure you have installed Nginx with the HTTP rewrite module. To install this we need to have pcre-library
If the above mentioned are done or if you already have them, then just add the below code in your nginx server block
if ($host !~* ^www\.) {
rewrite ^(.*)$ http://www.$host$1 permanent;
}
To remove www from every request you can use
if ($host = 'www.your_domain.com' ) {
rewrite ^/(.*)$ http://your_domain.com/$1 permanent;
}
so your server block will look like
server {
listen 80;
server_name test.com;
if ($host !~* ^www\.) {
rewrite ^(.*)$ http://www.$host$1 permanent;
}
client_max_body_size 10M;

The iBeacon output power is measured (calibrated) at a distance of 1 meter. Let's suppose that this is -59 dBm (just an example). The iBeacon will include this number as part of its LE advertisment.
The listening device (iPhone, etc), will measure the RSSI of the device. Let's suppose, for example, that this is, say, -72 dBm.
Since these numbers are in dBm, the ratio of the power is actually the difference in dB. So:
ratio_dB = txCalibratedPower - RSSI
To convert that into a linear ratio, we use the standard formula for dB:
ratio_linear = 10 ^ (ratio_dB / 10)
If we assume conservation of energy, then the signal strength must fall off as 1/r^2. So:
power = power_at_1_meter / r^2
. Solving for r, we get:
r = sqrt(ratio_linear)
In Javascript, the code would look like this:
function getRange(txCalibratedPower, rssi) {
var ratio_db = txCalibratedPower - rssi;
var ratio_linear = Math.pow(10, ratio_db / 10);
var r = Math.sqrt(ratio_linear);
return r;
}
Note, that, if you're inside a steel building, then perhaps there will be internal reflections that make the signal decay slower than 1/r^2. If the signal passes through a human body (water) then the signal will be attenuated. It's very likely that the antenna doesn't have equal gain in all directions. Metal objects in the room may create strange interference patterns. Etc, etc... YMMV.

I hit this in my service fabric project after the cert used to authenticate against our key vault expired and was rotated, which changed the thumbprint. I got this error because I had missed updating the thumbprint in the applicationManifest.xml file in this block which precisely does what other answers have suggested - to given NETWORK SERVICE (which all my exes run as, standard config for azure servicefabric cluster) permissions to access the LOCALMACHINE\MY cert store location.

package main

func FloatToString(input_num float64) string {

return strconv.FormatFloat(input_num, 'f', 6, 64)

}
If you just want as many digits precision as possible, then the special precision -1 uses the smallest number of digits necessary such that ParseFloat will return f exactly. Eg
strconv.FormatFloat(input_num, 'f', -1, 64)
Personally I find fmt
easier to use. (Playground link)
fmt.Printf("x = %.6f\n", 21312421.213123)
Or if you just want to convert the string
fmt.Sprintf("%.6f", 21312421.213123)

Just bumped into this post, by getting the same error, trying to test if two variables are both empty (or non-empty). That turns out to be a compound comparison - 7.3. Other Comparison Operators - Advanced Bash-Scripting Guide; and I thought I should note the following:
-e
-z
for testing empty variable (string)test
s and &&
them: [ ... ] && [ ... ]
-a
operator in a single test
: [ ... -a ... ]
Here is a working command (searching through all txt files in a directory, and dumping those that grep
finds contain both of two words):
find /usr/share/doc -name '*.txt' | while read file; do \
a1=$(grep -H "description" $file); \
a2=$(grep -H "changes" $file); \
[ ! -z "$a1" -a ! -z "$a2" ] && echo -e "$a1 \n $a2" ; \
done
Edit 12 Aug 2013: related problem note:
Note that when checking string equality with classic test
(single square bracket [
), you MUST have a space between the "is equal" operator, which in this case is a single "equals" =
sign (although two equals' signs ==
seem to be accepted as equality operator too). Thus, this fails (silently):
$ if [ "1"=="" ] ; then echo A; else echo B; fi
A
$ if [ "1"="" ] ; then echo A; else echo B; fi
A
$ if [ "1"="" ] && [ "1"="1" ] ; then echo A; else echo B; fi
A
$ if [ "1"=="" ] && [ "1"=="1" ] ; then echo A; else echo B; fi
A
... but add the space - and all looks good:
$ if [ "1" = "" ] ; then echo A; else echo B; fi
B
$ if [ "1" == "" ] ; then echo A; else echo B; fi
B
$ if [ "1" = "" -a "1" = "1" ] ; then echo A; else echo B; fi
B
$ if [ "1" == "" -a "1" == "1" ] ; then echo A; else echo B; fi

I have tried to use AjaxableResponseMixin in my project, but had ended up with the following error message:
ImproperlyConfigured: No URL to redirect to. Either provide a url or define a get_absolute_url method on the Model.
That is because the CreateView will return a redirect response instead of returning a HttpResponse when you to send JSON request to the browser. So I have made some changes to the AjaxableResponseMixin
. If the request is an ajax request, it will not call the super.form_valid
method, just call the form.save()
directly.

If you put
window.location.reload(true);
at the beginning of your page with no other condition qualifying why that code runs, the page will load and then continue to reload itself until you close your browser.
In this instance, your div
elements have been changed from block
level elements to inline
elements. A typical characteristic of inline
elements is that they respect the whitespace in the markup. This explains why a gap of space is generated between the elements. (example)
There are a few solutions that can be used to solve this.
Example 1 - Comment the whitespace out: (example)
<div>text</div><!--
--><div>text</div><!--
--><div>text</div><!--
--><div>text</div><!--
--><div>text</div>
Example 2 - Remove the line breaks: (example)
<div>text</div><div>text</div><div>text</div><div>text</div><div>text</div>
Example 3 - Close part of the tag on the next line (example)
<div>text</div
><div>text</div
><div>text</div
><div>text</div
><div>text</div>
Example 4 - Close the entire tag on the next line: (example)
<div>text
</div><div>text
</div><div>text
</div><div>text
</div><div>text
</div>
font-size
Since the whitespace between the inline
elements is determined by the font-size
, you could simply reset the font-size
to 0
, and thus remove the space between the elements.
Just set font-size: 0
on the parent elements, and then declare a new font-size
for the children elements. This works, as demonstrated here (example)
#parent {
font-size: 0;
}
#child {
font-size: 16px;
}
This method works pretty well, as it doesn't require a change in the markup; however, it doesn't work if the child element's font-size
is declared using em
units. I would therefore recommend removing the whitespace from the markup, or alternatively floating the elements and thus avoiding the space generated by inline
elements.
display: flex
In some cases, you can also set the display
of the parent element to flex
. (example)
This effectively removes the spaces between the elements in supported browsers. Don't forget to add appropriate vendor prefixes for additional support.
.parent {
display: flex;
}
.parent > div {
display: inline-block;
padding: 1em;
border: 2px solid #f00;
}
.parent {_x000D_
display: flex;_x000D_
}_x000D_
.parent > div {_x000D_
display: inline-block;_x000D_
padding: 1em;_x000D_
border: 2px solid #f00;_x000D_
}
_x000D_
<div class="parent">_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
</div>
_x000D_
It is incredibly unreliable to use negative margins to remove the space between inline
elements. Please don't use negative margins if there are other, more optimal, solutions.
// in foo.h
class Foo {
static const unsigned char* Msg;
};
// in foo.cpp
static const unsigned char Foo_Msg_data[] = {0x00,0x01};
const unsigned char* Foo::Msg = Foo_Msg_data;
max-length
is used for input
elements. Use text-overflow
property of CSS.
.claimedRight {
display:block; width: 250px;
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
}
"Egg" is a single-file importable distribution format for Python-related projects.
"The Quick Guide to Python Eggs" notes that "Eggs are to Pythons as Jars are to Java..."
Eggs actually are richer than jars; they hold interesting metadata such as licensing details, release dependencies, etc.
For future Googlers, If you get an error similar below after you trigger click for a polygon
"Uncaught TypeError: Cannot read property 'vertex' of undefined"

If you are using dataset to bind in a Grid, you can add the row after you fill in the sql data adapter:
adapter.Fill(ds);

Yes! Any class in Java can have multiple main methods. It's called Overloading (Overloaded methods are methods with same name but with different signatures) but there should only be one main method with parameters like this :- (String[] args) or (String args[])
For example :-public class E {
public static void main(String args){
System.out.println("Print A");
}
public static void main(String [] args){
System.out.println("Print B");
}
public static void main(int garbage){
System.out.println("Print C");
}
public static void main(int i){
System.out.println("Print D")
}
}
The output of the above program will be "Print B" as only that main method contains the correct method signature identified by the Javac compiler and it compiles that only and leaves the rest.

I just upgraded to TSVN 1.6.8.19260 on a WinXP and two Win7 machines. After upgrading, the overlay icons disappeared on all 3 machines. Under the above mentioned registry key, I only found the entry for offline files. I simply had to reinstall/repair the TSVN installation and the icons reappeared after a reboot. I've never detected that behaviour in any previous TSVN version and I certainly installed TSVN everytime the same way with the same permissions.

You can try these below views.
SELECT * FROM USER_SYS_PRIVS;
SELECT * FROM USER_TAB_PRIVS;
SELECT * FROM USER_ROLE_PRIVS;
DBAs and other power users can find the privileges granted to other users with the DBA_
versions of these same views. They are covered in the documentation .
Those views only show the privileges granted directly to the user. Finding all the privileges, including those granted indirectly through roles, requires more complicated recursive SQL statements:
select * from dba_role_privs connect by prior granted_role = grantee start with grantee = '&USER' order by 1,2,3;
select * from dba_sys_privs where grantee = '&USER' or grantee in (select granted_role from dba_role_privs connect by prior granted_role = grantee start with grantee = '&USER') order by 1,2,3;
select * from dba_tab_privs where grantee = '&USER' or grantee in (select granted_role from dba_role_privs connect by prior granted_role = grantee start with grantee = '&USER') order by 1,2,3,4;
rosipov's rule works great!
I use it on live sites to display a blank or special message ;) in place of a direct access attempt to files I'd rather to protect a bit from direct view. I think it's more fun than a 403 Forbidden.
So taking rosipov's rule to redirect any direct request to {gif,jpg,js,txt} files to 'messageforcurious' :
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^http://(www\.)?domain\.ltd [NC]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?domain\.ltd.*$ [NC]
RewriteRule \.(gif|jpg|js|txt)$ /messageforcurious [L]
I see it as a polite way to disallow direct acces to, say, a CMS sensible files like xml, javascript... with security in mind: To all these bots scrawling the web nowadays, I wonder what their algo will make from my 'messageforcurious'.
While you are using synchronized(this) you are using the class instance as a lock itself. This means that while lock is acquired by thread 1, the thread 2 should wait.
Suppose the following code:
public void method1() {
// do something ...
synchronized(this) {
a ++;
}
// ................
}
public void method2() {
// do something ...
synchronized(this) {
b ++;
}
// ................
}
Method 1 modifying the variable a and method 2 modifying the variable b, the concurrent modification of the same variable by two threads should be avoided and it is. BUT while thread1 modifying a and thread2 modifying b it can be performed without any race condition.
Unfortunately, the above code will not allow this since we are using the same reference for a lock; This means that threads even if they are not in a race condition should wait and obviously the code sacrifices concurrency of the program.
The solution is to use 2 different locks for two different variables:
public class Test {
private Object lockA = new Object();
private Object lockB = new Object();
public void method1() {
// do something ...
synchronized(lockA) {
a ++;
}
// ................
}
public void method2() {
// do something ...
synchronized(lockB) {
b ++;
}
// ................
}
}
The above example uses more fine grained locks (2 locks instead one (lockA and lockB for variables a and b respectively) and as a result allows better concurrency, on the other hand it became more complex than the first example ...

Original article: https://helpdeskgeek.com/networking/simulate-slow-internet-connection-testing/
Simulate Slow Connection using Chrome Go ahead and install Chrome if you don’t already have it installed on your system. Once you do, open a new tab and then press CTRL + SHIFT + I to open the developer tools window or click on the hamburger icon, then More tools and then Developer tools.
This will bring up the Developer Tools window, which will probably be docked on the right side of the screen. I prefer it docked at the bottom of the screen since you can see more data. To do this, click on the three vertical dots and then click on the middle dock position.
Now go ahead and click on the Network tab. On the right, you should see a label called No Throttling.
If you click on that, you’ll get a dropdown list of a pre-configured speed that you can use to simulate a slow connection.
The choices range from Offline to WiFi and the numbers are shown as Latency, Download, Upload. The slowest is GPRS followed by Regular 2G, then Good 2G, then Regular 3G, Good 3G, Regular 4G, DSL and then WiFi. Pick one of the options and then reload the page you are on or type in another URL in the address bar. Just make sure you are in the same tab where the developer tools are being displayed. The throttling only works for the tab you have it enabled for.
If you want to use your own specific values, you can click the Add button under Custom. Click on the Add Custom Profile button to add a new profile.
When using GPRS, it took www.google.com a whopping 16 seconds to load! Overall, this is a great tool that is built right into Chrome that you can use for testing your website load time on slower connections. If you have any questions, feel free to comment. Enjoy!

i may have missed this, as i didn't read the whole post here, but what i came up with seems deceptively simple. i haven't put this through the wringer, testing in all situations, but it seems like it should work just fine.
simply adjust the contentInset of the tableview by the height of the keyboard, and then scroll the cell to the bottom:
- (void)keyboardWasShown:(NSNotification *)aNotification
{
NSDictionary* info = [aNotification userInfo];
CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbSize.height, 0.0);
self.myTableView.contentInset = contentInsets;
self.myTableView.scrollIndicatorInsets = contentInsets;
[self.myTableView scrollToRowAtIndexPath:self.currentField.indexPath atScrollPosition:UITableViewScrollPositionBottom animated:YES];
}
and of course
- (void)keyboardWasHidden:(NSNotification *)aNotification
{
[UIView animateWithDuration:.3 animations:^(void)
{
self.myTableView.contentInset = UIEdgeInsetsZero;
self.myTableView.scrollIndicatorInsets = UIEdgeInsetsZero;
}];
}
is this too simple? am i missing something? so far it is working for me fine, but as i said, i haven't put it through the wringer...
This question wasn't asking explicitly about Docker, but I received the same error when I had a pom.xml file that was targeting 1.9...

... but then tried to run tests against a Docker container by specifying "maven" by itself.
docker run -t --rm -v m2_repository:/root/.m2/repository -v $(pwd):/work -w /work maven mvn -e test
For me, the fix was to target the exact version I needed.

[Long Running Process] The forever process will continue to run outputting log messages to the console. ex. forever -o out.log -e err.log my-script.js
and
[Daemon] The forever process will run as a daemon which will make the target process start in the background. This is extremely useful for remote starting simple node.js scripts without using nohup. It is recommended to run start with -o -l, & -e. ex. forever start -l forever.log -o out.log -e err.log my-daemon.js forever stop my-daemon.js

Another simple solution with +=
:
$y = 1;
for ($x = $y; $x <= 15; $y++) {
printf("The number of first paragraph is: $y <br>");
printf("The number of second paragraph is: $x+=2 <br>");
}
Try this. It uses the split
function which is a core part of javascript, nothing to do with jQuery.
var parts = html.split(":-"),
i, l
;
for (i = 0, l = parts.length; i < l; i += 2) {
$("#" + parts[i]).text(parts[i + 1]);
}

<script type="text/javascript">
$("#hideme").hide();
</script>
In this case I would recommend the CSS solution by Vega. But if you need something more complex (like an animation) you can use this approach.
This has some complications (see comments below). If you want this piece of script to really run as fast as possible you can't use jQuery, use native JS only and defer loading of all other scripts.
More flexible than select max()
is:
select distinct first_row(column_x) over (order by column_y,column_z,...) from Table_A
You can explicitly export it to the global scope with global.FOO = 5
. Then you simply need to require the file, and not even save your return value.
But really, you shouldn't do that. Keeping things properly encapsulated is a good thing. You have the right idea already, so keep doing what you're doing.
Try the above which will run with any list type.
public DataTable ListToDataTable<T>(IList<T> data)
{
PropertyDescriptorCollection props =
TypeDescriptor.GetProperties(typeof(T));
DataTable table = new DataTable();
for (int i = 0; i < props.Count; i++)
{
PropertyDescriptor prop = props[i];
table.Columns.Add(prop.Name, prop.PropertyType);
}
object[] values = new object[props.Count];
foreach (T item in data)
{
for (int i = 0; i < values.Length; i++)
{
values[i] = props[i].GetValue(item);
}
table.Rows.Add(values);
}
return table;
}
If you want to simulate the old anonymous way in Kotlin I found this worked perfectly.
btnNewWay!!.setOnClickListener(object:View.OnClickListener {
override fun onClick(v: View?) {
//Your Code Here!
}})
You can do one of the following:
<?php
$data = 'My data';
function menugen() {
global $data;
echo "[" . $data . "]";
}
menugen();
Or
<?php
$data = 'My data';
function menugen() {
echo "[" . $GLOBALS['data'] . "]";
}
menugen();
That being said, overuse of globals can lead to some poor code. It is usually better to pass in what you need. For example, instead of referencing a global database object you should pass in a handle to the database and act upon that. This is called dependency injection. It makes your life a lot easier when you implement automated testing (which you should).
The linked list holds operations on the shared data structure.
For example, if I have a stack, it will be manipulated with pushes and pops. The linked list would be a set of pushes and pops on the pseudo-shared stack. Each thread sharing that stack will actually have a local copy, and to get to the current shared state, it'll walk the linked list of operations, and apply each operation in order to its local copy of the stack. When it reaches the end of the linked list, its local copy holds the current state (though, of course, it's subject to becoming stale at any time).
In the traditional model, you'd have some sort of locks around each push and pop. Each thread would wait to obtain a lock, then do a push or pop, then release the lock.
In this model, each thread has a local snapshot of the stack, which it keeps synchronized with other threads' view of the stack by applying the operations in the linked list. When it wants to manipulate the stack, it doesn't try to manipulate it directly at all. Instead, it simply adds its push or pop operation to the linked list, so all the other threads can/will see that operation and they can all stay in sync. Then, of course, it applies the operations in the linked list, and when (for example) there's a pop it checks which thread asked for the pop. It uses the popped item if and only if it's the thread that requested this particular pop.
C++ provides a good mechanism to manage the life time of an object though class/struct constructs. This is one of the best features of C++ over other languages.
When you have member variables exposed through ref or pointer it violates the encapsulation in principle. This idiom enables the consumer of the class to change the state of an object of A without it(A) having any knowledge or control of it. It also enables the consumer to hold on to a ref/pointer to A's internal state, beyond the life time of the object of A. This is bad design. Instead the class could be refactored to hold a ref/pointer to the shared object (not own it) and these could be set using the constructor (Mandate the life time rules). The shared object's class may be designed to support multithreading/concurrency as the case may apply.
a = 0.000006;
b = 6;
c = a/b;
textbox.Text = c.ToString("0.000000");
As you requested:
textbox.Text = c.ToString("0.######");
This will only display out to the 6th decimal place if there are 6 decimals to display.
You can use:
SELECT IDENT_CURRENT('tablename')
to access the latest identity for a perticular table.
e.g. Considering following code:
INSERT INTO dbo.MyTable(columns....) VALUES(..........)
INSERT INTO dbo.YourTable(columns....) VALUES(..........)
SELECT IDENT_CURRENT('MyTable')
SELECT IDENT_CURRENT('YourTable')
This would yield to correct value for corresponding tables.
It returns the last IDENTITY
value produced in a table, regardless of the connection that created the value, and regardless of the scope of the statement that produced the value.
IDENT_CURRENT
is not limited by scope and session; it is limited to a specified table. IDENT_CURRENT
returns the identity value generated for a specific table in any session and any scope.
if the variable contains text then:
len(variable) != 0
of it does not
len(variable) == 0
If you want to get advantage of your local machine timezone you can use myDateTime.ToUniversalTime()
to get the UTC time from your local time or myDateTime.ToLocalTime()
to convert the UTC time to the local machine's time.
// convert UTC time from the database to the machine's time
DateTime databaseUtcTime = new DateTime(2011,6,5,10,15,00);
var localTime = databaseUtcTime.ToLocalTime();
// convert local time to UTC for database save
var databaseUtcTime = localTime.ToUniversalTime();
If you need to convert time from/to other timezones, you may use TimeZoneInfo.ConvertTime()
or TimeZoneInfo.ConvertTimeFromUtc()
.
// convert UTC time from the database to japanese time
DateTime databaseUtcTime = new DateTime(2011,6,5,10,15,00);
var japaneseTimeZone = TimeZoneInfo.FindSystemTimeZoneById("Tokyo Standard Time");
var japaneseTime = TimeZoneInfo.ConvertTimeFromUtc(databaseUtcTime, japaneseTimeZone);
// convert japanese time to UTC for database save
var databaseUtcTime = TimeZoneInfo.ConvertTimeToUtc(japaneseTime, japaneseTimeZone);
Let me extend Joseph's solution with the case insensitive version (online demo)
#include <string>
#include <cctype>
static bool EndsWithCaseInsensitive(const std::string& value, const std::string& ending) {
if (ending.size() > value.size()) {
return false;
}
return std::equal(ending.crbegin(), ending.crend(), value.crbegin(),
[](const unsigned char a, const unsigned char b) {
return std::tolower(a) == std::tolower(b);
}
);
}
This code handled every input for me in the whole site. It checks for the ENTER KEY inside an INPUT field and doesn't stop on TEXTAREA or other places.
$(document).on("keydown", "input", function(e){
if(e.which == 13){
event.preventDefault();
return false;
}
});
Use the new CSS filter
property.
Supported by webkit browsers, Firefox 34+ and Edge.
You can use this polyfill that will support FF < 34, IE6+.
You would use it like so:
/* Use -webkit- only if supporting: Chrome < 54, iOS < 9.3, Android < 4.4.4 */_x000D_
_x000D_
.shadow {_x000D_
-webkit-filter: drop-shadow( 3px 3px 2px rgba(0, 0, 0, .7));_x000D_
filter: drop-shadow( 3px 3px 2px rgba(0, 0, 0, .7));_x000D_
/* Similar syntax to box-shadow */_x000D_
}
_x000D_
<img src="https://upload.wikimedia.org/wikipedia/commons/c/ce/Star_wars2.svg" alt="" class="shadow" width="200">_x000D_
_x000D_
<!-- Or -->_x000D_
_x000D_
<svg class="shadow" ...>_x000D_
<rect x="10" y="10" width="200" height="100" fill="#bada55" />_x000D_
</svg>
_x000D_
This approach differs from the box-shadow
effect in that it accounts for opacity and does not apply the drop shadow effect to the box but rather to the corners of the svg element itself.
Please Note: This approach only works when the class is placed on the <svg>
element alone. You can NOT use this on an inline svg element such as <rect>
.
<!-- This will NOT work! -->
<svg><rect class="shadow" ... /></svg>

to use in onMenuItemClick(MenuItem item)
just do invalidateOptionsMenu();
item.setIcon(ContextCompat.getDrawable(this, R.drawable.ic_baseline_play_circle_outline_24px));
You should simply apply the following transformation to your input data array.
input_data = input_data.reshape((-1, image_side1, image_side2, channels))
function countWords(str) {
var regEx = /([^\u0000-\u007F]|\w)+/g;
return str.match(regEx).length;
}
Explanation:
/([^\u0000-\u007F]|\w)
matches word characters - which is great -> regex does the heavy lifting for us. (This pattern is based on the following SO answer: https://stackoverflow.com/a/35743562/1806956 by @Landeeyo)
+
matches the whole string of the previously specified word characters - so we basically group word characters.
/g
means it keeps looking till the end.
str.match(regEx)
returns an array of the found words - so we count its length.
Although the accepted response is a good answer, it overlooks failure scenarios. curl
will return 000
if there is an error in the request or there is a connection failure.
url='http://localhost:8080/'
status=$(curl --head --location --connect-timeout 5 --write-out %{http_code} --silent --output /dev/null ${url})
[[ $status == 500 ]] || [[ $status == 000 ]] && echo restarting ${url} # do start/restart logic
Note: this goes a little beyond the requested 500
status check to also confirm that curl
can even connect to the server (i.e. returns 000
).
Create a function from it:
failureCode() {
local url=${1:-http://localhost:8080}
local code=${2:-500}
local status=$(curl --head --location --connect-timeout 5 --write-out %{http_code} --silent --output /dev/null ${url})
[[ $status == ${code} ]] || [[ $status == 000 ]]
}
Test getting a 500
:
failureCode http://httpbin.org/status/500 && echo need to restart
Test getting error/connection failure (i.e. 000
):
failureCode http://localhost:77777 && echo need to start
Test not getting a 500
:
failureCode http://httpbin.org/status/400 || echo not a failure
The (un)safe way to do this - if you are ok with not using option explicit - is...
Not TypeName(myObj) = "Empty"
This also handles the case if the object has not been declared. This is useful if you want to just comment out a declaration to switch off some behaviour...
Dim myObj as Object
Not TypeName(myObj) = "Empty" '/ true, the object exists - TypeName is Object
'Dim myObj as Object
Not TypeName(myObj) = "Empty" '/ false, the object has not been declared
This works because VBA will auto-instantiate an undeclared variable as an Empty Variant type. It eliminates the need for an auxiliary Boolean to manage the behaviour.

See the following fiddle:
Include the following into build.gradle:
android.libraryVariants.all { variant ->
task("generate${variant.name}Javadoc", type: Javadoc) {
description "Generates Javadoc for $variant.name."
source = variant.javaCompile.source
ext.androidJar = "${android.plugin.sdkDirectory}/platforms/${android.compileSdkVersion}/android.jar"
classpath = files(variant.javaCompile.classpath.files) + files(ext.androidJar)
}
task("javadoc${variant.name}", type: Jar) {
classifier = "javadoc"
description "Bundles Javadoc into a JAR file for $variant.name."
from tasks["generate${variant.name}Javadoc"]
}
task("jar${variant.name}", type: Jar) {
description "Bundles compiled .class files into a JAR file for $variant.name."
dependsOn variant.javaCompile
from variant.javaCompile.destinationDir
exclude '**/R.class', '**/R$*.class', '**/R.html', '**/R.*.html'
}
}
You can then execute gradle with: ./gradlew clean javadocRelease jarRelease
which will build you your Jar and also a javadoc jar into the build/libs/
folder.
EDIT: With android gradle tools 1.10.+ getting the android SDK dir is different than before. You have to change the following (thanks Vishal!):
android.sdkDirectory
instead of
android.plugin.sdkDirectory
First of all float and double are both used for representation of numbers fractional numbers. So, the difference between the two stems from the fact with how much precision they can store the numbers.
For example: I have to store 123.456789 One may be able to store only 123.4567 while other may be able to store the exact 123.456789.
So, basically we want to know how much accurately can the number be stored and is what we call precision.
Quoting @Alessandro here
The precision indicates the number of decimal digits that are correct, i.e. without any kind of representation error or approximation. In other words, it indicates how many decimal digits one can safely use.
Float can accurately store about 7-8 digits in the fractional part while Double can accurately store about 15-16 digits in the fractional part
So, double can store double the amount of fractional part as of float. That is why Double is called double the float
Why would you use it if you already knew the class and were going to cast it? Why not just do it the old fashioned way and make the class like you always make it? There's no advantage to this over the way it's done normally. Is there a way to take the text and operate on it thusly:
label1.txt = "Pizza"
Magic(label1.txt) p = new Magic(lablel1.txt)(arg1, arg2, arg3);
p.method1();
p.method2();
If I already know its a Pizza there's no advantage to:
p = (Pizza)somefancyjunk("Pizza"); over
Pizza p = new Pizza();
but I see a huge advantage to the Magic method if it exists.
Noticed your comment about using it for email validation and needing a plugin, the validation plugin may help you, its located at http://bassistance.de/jquery-plugins/jquery-plugin-validation/, it comes with a e-mail rule as well.
For completeness here is another method for emulating INTERSECT
. Note that the IN (SELECT ...)
form suggested in other answers is generally more efficient.
Generally for a table called mytable
with a primary key called id
:
SELECT id
FROM mytable AS a
INNER JOIN mytable AS b ON a.id = b.id
WHERE
(a.col1 = "someval")
AND
(b.col1 = "someotherval")
(Note that if you use SELECT *
with this query you will get twice as many columns as are defined in mytable
, this is because INNER JOIN
generates a Cartesian product)
The INNER JOIN
here generates every permutation of row-pairs from your table. That means every combination of rows is generated, in every possible order. The WHERE
clause then filters the a
side of the pair, then the b
side. The result is that only rows which satisfy both conditions are returned, just like intersection two queries would do.
Take a look here: https://reacttraining.com/react-router/core/api/Route/exact-bool
exact: bool
When true, will only match if the path matches the location.pathname
exactly.
**path** **location.pathname** **exact** **matches?**
/one /one/two true no
/one /one/two false yes

I got this exception when trying to delete a folder where i deleted the file inside.
Example:
createFolder("folder");
createFile("folder/file");
deleteFile("folder/file");
deleteFolder("folder"); // error here
While deleteFile("folder/file");
returned that it was deleted, the folder will only be considered empty after the program restart.
On some operating systems it may not be possible to remove a file when it is open and in use by this Java virtual machine or other programs.

You should be able to convert your number to a Java Calendar, e.g.:
Calendar.getInstance().setTimeInMillis(myDate);
From there, the comparison shouldn't be too hard.
You could use URL sequence substitution with a dummy query string (if you want to use CURL and save a few keystrokes):
curl http://www.myurl.com/?[1-20]
If you have other query strings in your URL, assign the sequence to a throwaway variable:
curl http://www.myurl.com/?myVar=111&fakeVar=[1-20]
Check out the URL section on the man page: https://curl.haxx.se/docs/manpage.html
The problem comes from the fact that np.isnan()
does not handle string values correctly. For example, if you do:
np.isnan("A")
TypeError: ufunc 'isnan' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''
However the pandas version pd.isnull()
works for numeric and string values:
pd.isnull("A")
> False
pd.isnull(3)
> False
pd.isnull(np.nan)
> True
pd.isnull(None)
> True

Amiram Korach solution is indeed tidy. Here's an alternative for the sake of versatility.
var count = dtList.Count;
// Perform a reverse tracking.
for (var i = count - 1; i > -1; i--)
{
if (dtList[i]==string.Empty) dtList.RemoveAt(i);
}
// Keep only the unique list items.
dtList = dtList.Distinct().ToList();
Try requests instead of urllib and you don't need to bother with urlencode!
import requests
requests.get('http://youraddress.com', params=evt.fields)
EDIT:
If you need ordered name-value pairs or multiple values for a name then set params like so:
params=[('name1','value11'), ('name1','value12'), ('name2','value21'), ...]
instead of using a dictionary.
The accepted answer misses some rather significant locales. For example, the Chinese locales don't distinguish between the different scriptures (simplified han, traditional han). What's a main-land Chinese citizen who wants traditional han supposed to use - the Hong Kong setting?
I've taken this list of iOS locales, removed the strange POSIX entry, formatted it as Javascript and sorted it by value (so if you use an ordered object implementation and create a list by going through the keys and returning the value, it will show the human readable text in correct order). Also, this list both contains a main entry per language as well as all the region specific variants - this way you always have a designated fallback option, say if your interface has only defined the 'en' option - you wouldn't otherwise know on what to fall back on reliably.

This will apply to any form. No need of scrollview. do not forget to set delegate.
Make a var of uitextfield
var clickedTextField = UITextField()
In your viewdid load
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name:NSNotification.Name.UIKeyboardWillShow, object: nil);
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name:NSNotification.Name.UIKeyboardWillHide, object: nil);
Know the clicked text field. probably you are having textfields on the entire screen.
func textFieldDidBeginEditing(_ textField: UITextField) {
clickedTextField = textField
}
Check if the keyboard is covering textfield or not.
@objc func keyboardWillShow(sender: NSNotification,_ textField : UITextField) {
if let keyboardSize = (sender.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
if clickedTextField.frame.origin.y > keyboardSize.origin.y {
self.view.frame.origin.y = keyboardSize.origin.y - clickedTextField.center.y - 20
}
}
}
@objc func keyboardWillHide(sender: NSNotification) {
self.view.frame.origin.y = 0
}
Return to close keyboard
func textFieldShouldReturn(_ textField: UITextField) -> Bool { //delegate method
textField.resignFirstResponder()
return true
}
UPDATE : NSNotification.Name.UIKeyboardWillShow & NSNotification.Name.UIKeyboardWillHide are renamed to UIResponder.keyboardWillShowNotification & UIResponder.keyboardWillHideNotification respectively.
If you are using the two formulas at the same time, it will not work... Here is a simple spreadsheet with it working: https://docs.google.com/spreadsheet/ccc?key=0AiOy0YDBXjt4dDJSQWg1Qlp6TEw5SzNqZENGOWgwbGc If you are still getting problems I would need to know what type of erroneous result you are getting.
Today() returns a numeric integer value: Returns the current computer system date. The value is updated when your document recalculates. TODAY is a function without arguments.
Assuming i'm in a container with 15px padding, this is what i always use for the inner part:
width:auto;
right:15px;
left:15px;
That will stretch the inner part to whatever width it should be less the 15px either side.
It really depends on the application. For a normal project, I would recommend using only Access, but sometimes, the needs are specific and an Excel spreadsheet might be more appropriate.
For instance, in a project I had to develop for a former employer, the need was to give access to different persons on forms(pre-filled with some data, different for each person) and have them complete them, then re-import the data.
Since the form was using heavy number crunching, it made more sense to build it in Excel.
The Excel workbooks for the different persons were built from a template using VBA, then saved in a proper location, with the access rights on the folder.
All workbooks were attached as External tables to the workbooks, using named ranges. I could then query the workbooks from the Access Application. All administrative stuff was made from the db, but the end users only had access to their respective workbook.
Developping an Excel/Access application this way was a pleasant experience and the UI was more user-friendly than it would have been using Access.
I have to say that in this case, it would have taken a lot more time doing it in Access than it took using Excel. Also, the Application Object Model seems better though in Excel than in Access.
If you plan to use Excel as a front-end, do not forget to lock all the cells, but the editable ones and don't be affraid to use masked rows and columnns (to construct output tables for the access database, to perform intermediate calculations, etc).
You should also turn off autocalculation while importing data.
If You want to find a specific object via search function just try something like this:
function findArray(value){
let countLayer = dataLayer.length;
for(var x = 0 ; x < countLayer ; x++){
if(dataLayer[x].user){
let newArr = dataLayer[x].user;
let data = newArr[value];
return data;
}
}
return null;
}
findArray("id");
This is an example object:
layerObj = {
0: { gtm.start :1232542, event: "gtm.js"},
1: { event: "gtm.dom", gtm.uniqueEventId: 52},
2: { visitor id: "abcdef2345"},
3: { user: { id: "29857239", verified: "Null", user_profile: "Personal", billing_subscription: "True", partners_user: "adobe"}
}
Code will iterate and find the "user" array and will search for the object You seek inside.
My problem was when the array index changed every window refresh and it was either in 3rd or second array, but it does not matter.
Worked like a charm for Me!
In Your example it is a bit shorter:
function findArray(value){
let countLayer = Object.length;
for(var x = 0 ; x < countLayer ; x++){
if(Object[x].dinner === value){
return Object[x];
}
}
return null;
}
findArray('sushi');
Storing money as BIGINT
multiplied by 100 or more with the reason to use less storage space makes no sense in all "normal" situations.

DECIMAL(13,4)

.Little late to the party but why don't you guys try animation.No I am not telling you to manage animation controllers and disposing them off and all that stuff.theres a built-in widget for that called TweenAnimationBuilder.You can animate between values of any type,heres an example with a Duration class
TweenAnimationBuilder<Duration>(
duration: Duration(minutes: 3),
tween: Tween(begin: Duration(minutes: 3), end: Duration.zero),
onEnd: () {
print('Timer ended');
},
builder: (BuildContext context, Duration value, Widget child) {
final minutes = value.inMinutes;
final seconds = value.inSeconds % 60;
return Padding(
padding: const EdgeInsets.symmetric(vertical: 5),
child: Text('$minutes:$seconds',
textAlign: TextAlign.center,
style: TextStyle(
color: Colors.black,
fontWeight: FontWeight.bold,
fontSize: 30)));
}),
and You also get onEnd call back which notifies you when the animation completes;
here's the output
Default c++ mechanism for file IO is called streams.
Streams can be of three flavors: input, output and inputoutput.
Input streams act like sources of data. To read data from an input stream you use >>
operator:
istream >> my_variable; //This code will read a value from stream into your variable.
Operator >>
acts different for different types. If in the example above my_variable
was an int, then a number will be read from the strem, if my_variable
was a string, then a word would be read, etc.
You can read more then one value from the stream by writing istream >> a >> b >> c;
where a, b and c would be your variables.
Output streams act like sink to which you can write your data. To write your data to a stream, use <<
operator.
ostream << my_variable; //This code will write a value from your variable into stream.
As with input streams, you can write several values to the stream by writing something like this:
ostream << a << b << c;
Obviously inputoutput streams can act as both.
In your code sample you use cout
and cin
stream objects.
cout
stands for console-output and cin for console-input
. Those are predefined streams for interacting with default console.
To interact with files, you need to use ifstream
and ofstream
types.
Similar to cin
and cout
, ifstream
stands for input-file-stream
and ofstream
stands for output-file-stream
.
Your code might look like this:
#include <iostream>
#include <fstream>
using namespace std;
int start()
{
cout << "Welcome...";
// do fancy stuff
return 0;
}
int main ()
{
string usreq, usr, yn, usrenter;
cout << "Is this your first time using TEST" << endl;
cin >> yn;
if (yn == "y")
{
ifstream iusrfile;
ofstream ousrfile;
iusrfile.open("usrfile.txt");
iusrfile >> usr;
cout << iusrfile; // I'm not sure what are you trying to do here, perhaps print iusrfile contents?
iusrfile.close();
cout << "Please type your Username. \n";
cin >> usrenter;
if (usrenter == usr)
{
start ();
}
}
else
{
cout << "THAT IS NOT A REGISTERED USERNAME.";
}
return 0;
}
For further reading you might want to look at c++ I/O reference
There is an easier method than the other answers here, which require first deserializing into a c# class, and then turning it into a datatable.
It is possible to go directly to a datatable, with JSON.NET and code like this:
DataTable dt = (DataTable)JsonConvert.DeserializeObject(json, (typeof(DataTable)));
nil?
can be omitted in boolean contexts. Generally, you can use this to replicate the C# code:
return my_string.nil? || my_string.empty?
From dictionary.reference.com:
Computers. to analyze (a string of characters) in order to associate groups of characters with the syntactic units of the underlying grammar.
The context of the definition is the translation of program text or a language in the general sense into its component parts with respect to a defined grammar -- turning program text into code. In the context of a particular language keyword, though, it generally means to convert the string value of a fundamental data type into an internal representation of that data type. For example, the string "10" becomes the number (integer) 10.
I was facing the same issue and i found out that I was having two terminals in visual studio code, On first terminal it was already running my flutter project and on the other terminal I was running different solutions shared in this thread. Due to this reason no solution was working for me. So there are two ways you can solve this problem. 1- Restart visual studio code (it will automatically close the terminals) 2- Stop the terminal in which flutter project is already running and then run flutter clean command.
base_convert(uniqid('pass', true), 10, 36);
eg. e0m6ngefmj4
EDIT
As I've mentioned in comments, the length means that brute force attacks would work better against it then timing attacks so it's not really relevant to worry about "how secure the random generator was." Security, specifically for this use case, needs to complement usability so the above solution is actually good enough for the required problem.
However, just in case you stumbled upon this answer while searching for a secure random string generator (as I assume some people have based on the responses), for something such as generating tokens, here is how a generator of such codes would look like:
function base64urlEncode($data) {
return rtrim(strtr(base64_encode($data), '+/', '-_'), '=');
}
function secureId($length = 32) {
if (function_exists('openssl_random_pseudo_bytes')) {
$bytes = openssl_random_pseudo_bytes($length);
return rtrim(strtr(base64_encode($bytes), '+/', '0a'), '=');
}
else { // fallback to system bytes
error_log("Missing support for openssl_random_pseudo_bytes");
$pr_bits = '';
$fp = @fopen('/dev/urandom', 'rb');
if ($fp !== false) {
$pr_bits .= @fread($fp, $length);
@fclose($fp);
}
if (strlen($pr_bits) < $length) {
error_log('unable to read /dev/urandom');
throw new \Exception('unable to read /dev/urandom');
}
return base64urlEncode($pr_bits);
}
}
Product "Clean" was the solution for me.
WARNING: operating on strings alone will only work with ASCII and will count wrong when input is a non-ASCII UTF-8 encoded character, and will probably even corrupt characters since it cuts multibyte chars mid-sequence.
Here's a UTF-8-aware version:
// NOTE: this isn't multi-Unicode-codepoint aware, like specifying skintone or
// gender of an emoji: https://unicode.org/emoji/charts/full-emoji-modifiers.html
func substr(input string, start int, length int) string {
asRunes := []rune(input)
if start >= len(asRunes) {
return ""
}
if start+length > len(asRunes) {
length = len(asRunes) - start
}
return string(asRunes[start : start+length])
}
I will add one more "future-proof" reply
In ECMAScript 6, you can use the Spread syntax:
let arr1 = [0, 1, 2];_x000D_
let arr2 = [3, 4, 5];_x000D_
arr1.push(...arr2);_x000D_
_x000D_
console.log(arr1)
_x000D_
Spread syntax is not yet included in all major browsers. For the current compatibility, see this (continuously updated) compatibility table.
You can, however, use spread syntax with Babel.js.
edit:
See Jack Giffin's reply below for more comments on performance. It seems concat is still better and faster than spread operator.
public static void main(String[] args) {
int[] arr = {0,12,74,56,2,63,45};
int f1 = 1, f2 = 0, temp = 0;
int num = 0;
for (int i = 0; i < arr.length; i++){
num = arr[i];
if (f1 < num) {
temp = f1;
f1 = num;
num = temp;
}
if (f2 < num) {
temp = f2;
f2 = num;
num = temp;
}
}
System.out.println("First Highest " + f1 + " Second Highest " + f2 + " Third " + num);
}
The answer from las3rjock, which somehow is the answer accepted by the OP, is incorrect--the code doesn't run, nor is it valid matplotlib syntax; that answer provides no runnable code and lacks any information or suggestion that the OP might find useful in writing their own code to solve the problem in the OP.
Given that it's the accepted answer and has already received several up-votes, I suppose a little deconstruction is in order.
First, calling subplot does not give you multiple plots; subplot is called to create a single plot, as well as to create multiple plots. In addition, "changing plt.figure(i)" is not correct.
plt.figure() (in which plt or PLT is usually matplotlib's pyplot library imported and rebound as a global variable, plt or sometimes PLT, like so:
from matplotlib import pyplot as PLT
fig = PLT.figure()
the line just above creates a matplotlib figure instance; this object's add_subplot method is then called for every plotting window (informally think of an x & y axis comprising a single subplot). You create (whether just one or for several on a page), like so
fig.add_subplot(111)
this syntax is equivalent to
fig.add_subplot(1,1,1)
choose the one that makes sense to you.
Below I've listed the code to plot two plots on a page, one above the other. The formatting is done via the argument passed to add_subplot. Notice the argument is (211) for the first plot and (212) for the second.
from matplotlib import pyplot as PLT
fig = PLT.figure()
ax1 = fig.add_subplot(211)
ax1.plot([(1, 2), (3, 4)], [(4, 3), (2, 3)])
ax2 = fig.add_subplot(212)
ax2.plot([(7, 2), (5, 3)], [(1, 6), (9, 5)])
PLT.show()
Each of these two arguments is a complete specification for correctly placing the respective plot windows on the page.
211 (which again, could also be written in 3-tuple form as (2,1,1) means two rows and one column of plot windows; the third digit specifies the ordering of that particular subplot window relative to the other subplot windows--in this case, this is the first plot (which places it on row 1) hence plot number 1, row 1 col 1.
The argument passed to the second call to add_subplot, differs from the first only by the trailing digit (a 2 instead of a 1, because this plot is the second plot (row 2, col 1).
An example with more plots: if instead you wanted four plots on a page, in a 2x2 matrix configuration, you would call the add_subplot method four times, passing in these four arguments (221), (222), (223), and (224), to create four plots on a page at 10, 2, 8, and 4 o'clock, respectively and in this order.
Notice that each of the four arguments contains two leadings 2's--that encodes the 2 x 2 configuration, ie, two rows and two columns.
The third (right-most) digit in each of the four arguments encodes the ordering of that particular plot window in the 2 x 2 matrix--ie, row 1 col 1 (1), row 1 col 2 (2), row 2 col 1 (3), row 2 col 2 (4).
From the Javadoc:
Sometimes several tests need to share computationally expensive setup (like logging into a database). While this can compromise the independence of tests, sometimes it is a necessary optimization. Annotating a
public static void
no-arg method with@BeforeClass
causes it to be run once before any of the test methods in the class. The@BeforeClass
methods of superclasses will be run before those the current class.
Since most of the answers to this question are between 2009 and 2014 (except for a comment in 2018), there should be an update to this.
I found a solution to the wrap-text problem brought up by Spongman on Jun 11 '14 at 23:20. He has an example here: jsfiddle.net/vPpD4
If you add the following in the CSS under the div tag in the jsfiddle.net/vPpD4 example, you get the desired wrap-text effect that I think Spongman was asking about. I don't know how far back this is applicable, but this works in all of the current (as of Dec 2020/Jan 2021) browsers available for Windows computers. Note: I have not tested this on the Apple Safari browser. I have also not tested this on any mobile devices.
div img {
float: left;
}
.clearfix::after {
content: "";
clear: both;
display: table;
}
I also added a border around the image, just so that the reader will understand where the edge of the image is and why the text wraps as it does. The resulting example looks is here: http://jsfiddle.net/tqg7hLzk/
Component code:
import { Component } from "@angular/core";
@Component({
templateUrl:"home.html"
})
export class HomePage {
public items: Array<string>;
constructor() {
this.items = ["item1", "item2", "item3"]
}
public open(event, item) {
alert('Open ' + item);
}
}
View:
<ion-header>
<ion-navbar primary>
<ion-title>
<span>My App</span>
</ion-title>
</ion-navbar>
</ion-header>
<ion-content>
<ion-list>
<ion-item *ngFor="let item of items" (click)="open($event, item)">
{{ item }}
</ion-item>
</ion-list>
</ion-content>
As you can see in the code, I'm declaring the click handler like this (click)="open($event, item)"
and sending both the event and the item (declared in the *ngFor
) to the open()
method (declared in the component code).
If you just want to show the item and you don't need to get info from the event, you can just do (click)="open(item)"
and modify the open
method like this public open(item) { ... }
I found this to work for me: GetHostByName("");

Http is stateless. In order to authorize you, you have to "sign" every single request you're sending to server.
Token authentication
A request to the server is signed by a "token" - usually it means setting specific http headers, however, they can be sent in any part of the http request (POST body, etc.)
Pros:
<img src="http://bank.com?withdraw=1000&to=myself" />
, and if you're logged in via cookie authentication to bank.com, and bank.com doesn't have any means of XSRF protection, I'll withdraw money from your account simply by the fact that your browser will trigger an authorized GET request to that url.) Note there are anti forgery measure you can do with cookie-based authentication - but you have to implement those.Cookie authentication
Overall, I'd say tokens give you better flexibility, (since you're not bound to single domain). The downside is you have to do quite some coding by yourself.
This kind of code perhaps should work for You

You create an interface first, then define a method, which would act as a callback. In this example we would have two classes, one classA and another classB
Interface:
public interface OnCustomEventListener{
public void onEvent(); //method, which can have parameters
}
the listener itself in classB (we only set the listener in classB)
private OnCustomEventListener mListener; //listener field
//setting the listener
public void setCustomEventListener(OnCustomEventListener eventListener) {
this.mListener=eventListener;
}
in classA, how we start listening for whatever classB has to tell
classB.setCustomEventListener(new OnCustomEventListener(){
public void onEvent(){
//do whatever you want to do when the event is performed.
}
});
how do we trigger an event from classB (for example on button pressed)
if(this.mListener!=null){
this.mListener.onEvent();
}
P.S. Your custom listener may have as many parameters as you want
A few considerations on the subject:
The parenthesis:
The browser (engine/parser) associates the keyword function with
[optional name]([optional parameters]){...code...}
So in an expression like function(){}() the last parenthesis makes no sense.
Now think at
name=function(){} ; name() !?
Yes, the first pair of parenthesis force the anonymous function to turn into a variable (stored expression) and the second launches evaluation/execution, so ( function(){} )() makes sense.
The utility: ?
For executing some code on load and isolate the used variables from the rest of the page especially when name conflicts are possible;
Replace eval("string") with
(new Function("string"))()
Wrap long code for " =?: " operator like:
result = exp_to_test ? (function(){... long_code ...})() : (function(){...})();
In my case, I was using a custom index, that index had no route and such would trigger the exception case code. The exception case bug still exists and still masks the real issue, however I was able to work around this by testing the connectivity with other tools such as nc -vzw1 myindex.example.org 443
and retrying when the network was up.
This has probably been corrected, but... apparently firefox has a caching problem which is the cause of javascript functions not being recognized.. I really don't know the specifics, but if you clear your cache that will fix the problem (until your cache is full again... not a good solution).. I've been looking around to see if firefox has a real solution to this, but so far nothing... oh not all versions, I think it may be only in some 3.6.x versions, not sure...
Yes, use the rendered
attribute.
<h:form rendered="#{some boolean condition}">
You usually tie it to the model rather than letting the model grab the component and manipulate it.
E.g.
<h:form rendered="#{bean.booleanValue}" />
<h:form rendered="#{bean.intValue gt 10}" />
<h:form rendered="#{bean.objectValue eq null}" />
<h:form rendered="#{bean.stringValue ne 'someValue'}" />
<h:form rendered="#{not empty bean.collectionValue}" />
<h:form rendered="#{not bean.booleanValue and bean.intValue ne 0}" />
<h:form rendered="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />
Note the importance of keyword based EL operators such as gt
, ge
, le
and lt
instead of >
, >=
, <=
and <
as angle brackets <
and >
are reserved characters in XML. See also this related Q&A: Error parsing XHTML: The content of elements must consist of well-formed character data or markup.
As to your specific use case, let's assume that the link is passing a parameter like below:
<a href="page.xhtml?form=1">link</a>
You can then show the form as below:
<h:form rendered="#{param.form eq '1'}">
(the #{param}
is an implicit EL object referring to a Map
representing the request parameters)
Your linker (ld) obviously doesn't like the order in which make arranges the GCC arguments so you'll have to change your Makefile a bit:
CC=gcc
CFLAGS=-Wall
LDFLAGS=-lm
.PHONY: all
all: client
.PHONY: clean
clean:
$(RM) *~ *.o client
OBJECTS=client.o
client: $(OBJECTS)
$(CC) $(CFLAGS) $(OBJECTS) -o client $(LDFLAGS)
In the line defining the client target change the order of $(LDFLAGS) as needed.
Here is a modified version of the chosen answer:
getMonth("Feb")
function getMonth(month) {
d = new Date().toString().split(" ")
d[1] = month
d = new Date(d.join(' ')).getMonth()+1
if(!isNaN(d)) {
return d
}
return -1;
}
Angular 4 - Solution to address the ordering of the optional parameter:
DO THIS:
const appRoutes: Routes = [
{path: '', component: HomeComponent},
{path: 'products', component: ProductsComponent},
{path: 'products/:id', component: ProductsComponent}
]
Note that the products
and products/:id
routes are named exactly the same. Angular 4 will correctly follow products
for routes with no parameter, and if a parameter it will follow products/:id
.
However, the path for the non-parameter route products
must not have a trailing slash, otherwise angular will incorrectly treat it as a parameter-path. So in my case, I had the trailing slash for products and it wasn't working.
DON'T DO THIS:
...
{path: 'products/', component: ProductsComponent},
{path: 'products/:id', component: ProductsComponent},
...
Add
@Produces({"image/jpeg,image/png"})
to
@POST
@Path("/pdf")
@Consumes({ MediaType.MULTIPART_FORM_DATA })
@Produces({"image/jpeg,image/png"})
//@Produces("text/plain")
public Response uploadPdfFile(@FormDataParam("file") InputStream fileInputStream,@FormDataParam("file") FormDataContentDisposition fileMetaData) throws Exception {
...
}
I believe that I have the simplest answer. You don't need the string.h library in this program, nor the stdbool.h library. Simply using pointers and pointer arithmetic will help you become a better C programmer.
Simply return 0 for False (no substring found), or 1 for True (yes, a substring "sub" is found within the overall string "str"):
#include <stdlib.h>
int is_substr(char *str, char *sub)
{
int num_matches = 0;
int sub_size = 0;
// If there are as many matches as there are characters in sub, then a substring exists.
while (*sub != '\0') {
sub_size++;
sub++;
}
sub = sub - sub_size; // Reset pointer to original place.
while (*str != '\0') {
while (*sub == *str && *sub != '\0') {
num_matches++;
sub++;
str++;
}
if (num_matches == sub_size) {
return 1;
}
num_matches = 0; // Reset counter to 0 whenever a difference is found.
str++;
}
return 0;
}
try the following example. Image overlay with text on image. demo
<div class="thumbnail">

Here is another way not depending on a library but using a regex.
You can use this single line:
text.matches("\\A\\p{ASCII}*\\z")
Whole example program:
public class Main {
public static void main(String[] args) {
char nonAscii = 0x00FF;
String asciiText = "Hello";
String nonAsciiText = "Buy: " + nonAscii;
System.out.println(asciiText.matches("\\A\\p{ASCII}*\\z"));
System.out.println(nonAsciiText.matches("\\A\\p{ASCII}*\\z"));
}
}
Yes it's the exact same thing in Python 2:
d.values()
In Python 3 (where dict.values
returns a view of the dictionary’s values instead):
list(d.values())
You can iterate over "a file", which produces lines, including the trailing newline character. To make a "virtual file" out of a string, you can use StringIO
:
import io # for Py2.7 that would be import cStringIO as io
for line in io.StringIO(foo):
print(repr(line))
I'm surprised AutoMapper hasn't come up as an answer.
As is clear from all the previous answers, you cannot do the typecast. However, using AutoMapper, in a few lines of code you can have a new SkyfilterClient
instantiated based on an existing NetworkClient
.
In essence, you would put the following where you are currently doing your typecasting:
using AutoMapper;
...
// somewhere, your network client was declared
var existingNetworkClient = new NetworkClient();
...
// now we want to type-cast, but we can't, so we instantiate using AutoMapper
AutoMapper.Mapper.CreateMap<NetworkClient, SkyfilterClient>();
var skyfilterObject = AutoMapper.Mapper.Map<SkyfilterClient>(existingNetworkClient);
Here's a full-blown example:
public class Vehicle
{
public int NumWheels { get; set; }
public bool HasMotor { get; set; }
}
public class Car: Vehicle
{
public string Color { get; set; }
public string SteeringColumnStyle { get; set; }
}
public class CarMaker
{
// I am given vehicles that I want to turn into cars...
public List<Car> Convert(List<Vehicle> vehicles)
{
var cars = new List<Car>();
AutoMapper.Mapper.CreateMap<Vehicle, Car>(); // Declare that we want some automagic to happen
foreach (var vehicle in vehicles)
{
var car = AutoMapper.Mapper.Map<Car>(vehicle);
// At this point, the car-specific properties (Color and SteeringColumnStyle) are null, because there are no properties in the Vehicle object to map from.
// However, car's NumWheels and HasMotor properties which exist due to inheritance, are populated by AutoMapper.
cars.Add(car);
}
return cars;
}
}
For me the following seemed to work.
git pull --tags
I put the JRE folder from the JDK installation directory to the Eclipse installation directory (the folder which contains the eclipse.exe file). It worked for me.
The easiest way I found
Dialog dialog=new Dialog(this,android.R.style.Theme_Black_NoTitleBar_Fullscreen);
dialog.setContentView(R.layout.frame_help);
dialog.show();
long/int to the byte array looks like exact purpose of struct.pack
. For long integers that exceed 4(8) bytes, you can come up with something like the next:
>>> limit = 256*256*256*256 - 1
>>> i = 1234567890987654321
>>> parts = []
>>> while i:
parts.append(i & limit)
i >>= 32
>>> struct.pack('>' + 'L'*len(parts), *parts )
'\xb1l\x1c\xb1\x11"\x10\xf4'
>>> struct.unpack('>LL', '\xb1l\x1c\xb1\x11"\x10\xf4')
(2976652465L, 287445236)
>>> (287445236L << 32) + 2976652465L
1234567890987654321L
Since Python 3 is fairly mainstream, I wanted to include a pathlib
answer, as I believe that it is probably now a better tool for accessing file and path information.
from pathlib import Path
current_file: Path = Path(__file__).resolve()
If you are seeking the directory of the current file, it is as easy as adding .parent
to the Path()
statement:
current_path: Path = Path(__file__).parent.resolve()
Modern Javascript implementations with the template
syntax using backticks are also an easy way to assign an HTML block of code to a variable:
const firstName = 'Sam';
const fullName = 'Sam Smith';
const htmlString = `<h1>Hello ${fullName}!</h1><p>This is some content \
that will display. You can even inject your first name, ${firstName}, \
in the code.</p><p><a href="http://www.google.com">Search</a> for \
stuff on the Google website.</p>`;
npm start
runs a script that the app maker built for easy starting of the app
npm install
installs all the packages in package.json
run npm install
first
then run npm start
Type:
powershell -executionpolicy bypass -File .\Test.ps1
NOTE: Here Test.ps1
is the PowerShell script.
imo there's a better answer for this using Snippets
Create a snippet with a definition like this:
"name_of_your_snippet": {
"scope": "javascript,html",
"prefix": "name_of_your_snippet",
"body": "<${0:b}>$TM_SELECTED_TEXT</${0:b}>"
}
Then bind it to a key in keybindings.json E.g. like this:
{
"key": "alt+w",
"command": "editor.action.insertSnippet",
"args": { "name": "name_of_your_snippet" }
}
I think this should give you exactly the same result as htmltagwrap but without having to install an extension.
It will insert tags around selected text, defaults to <b>
tag & selects the tag so typing lets you change it.
If you want to use a different default tag just change the b
in the body
property of the snippet.
It works for me :).
div.parent {
display: flex;
align-items: center;
justify-content: center;
height: 100vh;
}
If you reset the result set to the top, using rs.absolute(1)
you won't get exhaused result set.
while (rs.next) {
System.out.println(rs.getString(1));
}
rs.absolute(1);
System.out.println(rs.getString(1));
You can also use rs.first() instead of rs.absolute(1), it does the same.
Usually (same as I do in mysql/postgres) I stores dates in int(mysql/post) or text(sqlite) to store them in the timestamp format.
Then I will convert them into Date objects and perform actions based on user TimeZone

It is not possible to limit the number of visible elements in the select dropdown (if you use it as dropdown box and not as list).
But you could use javascript/jQuery to replace this selectbox with something else, which just looks like a dropdown box. Then you can handle the height of dropdown as you want.
jNice would be a jQuery plugin which has such features. But there also exists many alternatives for that.
mydict = {'a': 'one', 'b': 'two', 'c': 'three'}
mykeys = [*mydict] #list of keys
myvals = [*mydict.values()] #list of values
print(mykeys)
print(myvals)
Output
['a', 'b', 'c']
['one', 'two', 'three']

If you don't care about legacy browsers:
if ( bank_holidays.indexOf( '06/04/2012' ) > -1 )
if you do care about legacy browsers, there is a shim available on MDN. Otherwise, jQuery provides an equivalent function:
if ( $.inArray( '06/04/2012', bank_holidays ) > -1 )
The problem is here:
answer = newList.sort()
sort
does not return the sorted list; rather, it sorts the list in place.
Use:
answer = sorted(newList)
Extracting a specific folder (directory) within war file:
# unzip <war file> '<folder to extract/*>' -d <destination path>
unzip app##123.war 'some-dir/*' -d extracted/
You get ./extracted/some-dir/
as a result.
This way should work, change "char" to "Character":
public static void main(String[] args){
Character[] list = {'m', 'e', 'y'};
System.out.println(Arrays.asList(list).indexOf('e')); // print "1"
}
Many years later, I discover this question. After reading every answer and comment, I thought I could clarify a few details... This could be useful for people who get here through Google search.
The question is specifically about using "extern" functions, so I will ignore the use of "extern" with global variables.
Let's define 3 function prototypes:
//--------------------------------------
//Filename: "my_project.H"
extern int function_1(void);
static int function_2(void);
int function_3(void);
The header file can be used by the main source code as follows:
//--------------------------------------
//Filename: "my_project.C"
#include "my_project.H"
void main(void){
int v1 = function_1();
int v2 = function_2();
int v3 = function_3();
}
int function_2(void) return 1234;
In order to compile and link, we must define "function_2" in the same source code file where we call that function. The two other functions could be defined in different source code ".C" or they may be located in any binary file (.OBJ, *.LIB, *.DLL), for which we may not have the source code.
Let's include again the header "my_project.H" in a different "*.C" file to understand better the difference. In the same project, we add the following file:
//--------------------------------------
//Filename: "my_big_project_splitted.C"
#include "my_project.H"
void old_main_test(void){
int v1 = function_1();
int v2 = function_2();
int v3 = function_3();
}
int function_2(void) return 5678;
int function_1(void) return 12;
int function_3(void) return 34;
Important features to notice:
When a function is defined as "static" in a header file, the compiler/linker must find an instance of a function with that name in each module which uses that include file.
A function which is part of the C library can be replaced in only one module by redefining a prototype with "static" only in that module. For example, replace any call to "malloc" and "free" to add memory leak detection feature.
The specifier "extern" is not really needed for functions. When "static" is not found, a function is always assumed to be "extern'.
However, "extern" is not the default for variables. Normally, any header file that defines variables to be visible across many modules needs to use "extern". The only exception would be if a header file is guaranteed to be included from one and only one module.
Many project manager would then require that such variable be placed at the beginning of the module, not inside any header file. Some large projects, such as the video game emulator "Mame" even require that such variable appears only above the first function using them.
Simplest solution with OP's existing code (list items already have got padding) is to add following code:
listView.setDivider(new ColorDrawable(Color.TRANSPARENT)); //hide the divider
listView.setClipToPadding(false); // list items won't clip, so padding stays
This SO answer helped me.
Note: You may face a bug of the list item recycling too soon on older platforms, as has been asked here.
final ListView lv = (ListView) findViewById(R.id.ListView01);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) {
String selectedFromList =(String) (lv.getItemAtPosition(myItemInt));
}
});
I hope this fixes your problem.
Welcome to Microsoft Marketing Speak hell. With the 2012 release of SQL Server, the BIDS, Business Intelligence Designer Studio, plugin for Visual Studio was renamed to SSDT, SQL Server Data Tools. SSDT is available for 2010 and 2012. The problem is, there are two different products called SSDT.
There is SSDT which replaces the database designer thing which was called Data Dude in VS 2008 and in 2010 became database projects. That a free install and if you snag the web installer, that's what you get when you install SSDT. It puts the correct project templates and such into Visual Studio.
There's also the SSDT which is the "BIDS" replacement for developing SSIS, SSRS and SSAS stuff. As of March 2013, it is now available for the 2012 release of Visual Studio. The download is labeled SSDTBI_VS2012_X86.msi Perhaps that's a signal on how the product is going to be referred to in marketing materials. Download links are
None the less, we have Business Intelligence projects available to us in Visual Studio 2012. And the people did rejoice and did feast upon the lambs and toads and tree-sloths and fruit-bats and orangutans and breakfast cereals

It should be mentioned that it is an option to completely leave authentication issues to the front controller, e.g. an Apache Webserver and evaluate the HttpServletRequest.getRemoteUser() instead, which is the JAVA representation for the REMOTE_USER environment variable. This allows also sophisticated log in designs such as Shibboleth authentication. Filtering Requests to a servlet container through a web server is a good design for production environments, often mod_jk is used to do so.
You can't do it in pure Lua without eating CPU, but there's a simple, non-portable way:
os.execute("sleep 1")
(it will block)
Obviously, this only works on operating systems for which "sleep 1" is a valid command, for instance Unix, but not Windows.
