The short answer to this question is that none of these values are a reliable indicator of how much memory an executable is actually using, and none of them are really appropriate for debugging a memory leak.
Private Bytes refer to the amount of memory that the process executable has asked for - not necessarily the amount it is actually using. They are "private" because they (usually) exclude memory-mapped files (i.e. shared DLLs). But - here's the catch - they don't necessarily exclude memory allocated by those files. There is no way to tell whether a change in private bytes was due to the executable itself, or due to a linked library. Private bytes are also not exclusively physical memory; they can be paged to disk or in the standby page list (i.e. no longer in use, but not paged yet either).
Working Set refers to the total physical memory (RAM) used by the process. However, unlike private bytes, this also includes memory-mapped files and various other resources, so it's an even less accurate measurement than the private bytes. This is the same value that gets reported in Task Manager's "Mem Usage" and has been the source of endless amounts of confusion in recent years. Memory in the Working Set is "physical" in the sense that it can be addressed without a page fault; however, the standby page list is also still physically in memory but not reported in the Working Set, and this is why you might see the "Mem Usage" suddenly drop when you minimize an application.
Virtual Bytes are the total virtual address space occupied by the entire process. This is like the working set, in the sense that it includes memory-mapped files (shared DLLs), but it also includes data in the standby list and data that has already been paged out and is sitting in a pagefile on disk somewhere. The total virtual bytes used by every process on a system under heavy load will add up to significantly more memory than the machine actually has.
So the relationships are:
There's another problem here; just as shared libraries can allocate memory inside your application module, leading to potential false positives reported in your app's Private Bytes, your application may also end up allocating memory inside the shared modules, leading to false negatives. That means it's actually possible for your application to have a memory leak that never manifests itself in the Private Bytes at all. Unlikely, but possible.
Private Bytes are a reasonable approximation of the amount of memory your executable is using and can be used to help narrow down a list of potential candidates for a memory leak; if you see the number growing and growing constantly and endlessly, you would want to check that process for a leak. This cannot, however, prove that there is or is not a leak.
One of the most effective tools for detecting/correcting memory leaks in Windows is actually Visual Studio (link goes to page on using VS for memory leaks, not the product page). Rational Purify is another possibility. Microsoft also has a more general best practices document on this subject. There are more tools listed in this previous question.
I hope this clears a few things up! Tracking down memory leaks is one of the most difficult things to do in debugging. Good luck.
Just use DataRow.IsNull. It has overrides accepting a column index, a column name, or a DataColumn object as parameters.
Example using the column index:
if (table.rows[0].IsNull(0))
{
//Whatever I want to do
}
And although the function is called IsNull
it really compares with DbNull
(which is exactly what you need).
What if I want to check for DbNull but I don't have a DataRow? Use Convert.IsDBNull.
According to String class documentation they are equivalent.
Documentation for String(String original)
also says that: Unless an explicit copy of original is needed, use of this constructor is unnecessary since Strings are immutable.
Look for other responses, because it seems that Java documentation is misleading :(

I'd like to address a particular aspect of this question, as captured in this comment:
OAuth: before granting access to some feature, authentication must be done, right ?. so OAuth = what OpenId does + grants access to some features ? – Hassan Makarov Jun 21 at 1:57
Yes... and no. The answer is subtle, so bear with me.
When the OAuth flow redirects you to a target service (the OAuth provider, that is), it is likely that you'll need to authenticate with that service before a token will be handed back to the client application/service. The resulting token then allows the client app to make requests on behalf of a given user.
Note the generality of that last sentence: specifically, I wrote "on behalf of a given user", not "on behalf of you". It's a common error to assume that "having a capability to interact with a resource owned by a given user" implies "you and the owner of the target resource(s) are one in the same".
Don't make this mistake.
While it's true that you authenticate with the OAuth provider (say, by user name and password, or maybe SSL client certs, or some other means), what the client gets in return should not necessarily be taken as proof of identity. An example would be a flow in which access to another user's resources was delegated to you (and by proxy, the OAuth client). Authorization does not imply authentication.
To handle authentication, you'll likely want to look into OpenID Connect, which is essentially another layer on top of the foundation set by OAuth 2.0. Here's a quote that captures (in my opinion) the most salient points regarding OpenID Connect (from https://oauth.net/articles/authentication/):
OpenID Connect is an open standard published in early 2014 that defines an interoperable way to use OAuth 2.0 to perform user authentication. In essence, it is a widely published recipe for chocolate fudge that has been tried and tested by a wide number and variety of experts. Instead of building a different protocol to each potential identity provider, an application can speak one protocol to as many providers as they want to work with. Since it's an open standard, OpenID Connect can be implemented by anyone without restriction or intellectual property concerns.
OpenID Connect is built directly on OAuth 2.0 and in most cases is deployed right along with (or on top of) an OAuth infrastructure. OpenID Connect also uses the JSON Object Signing And Encryption (JOSE) suite of specifications for carrying signed and encrypted information around in different places. In fact, an OAuth 2.0 deployment with JOSE capabilities is already a long way to defining a fully compliant OpenID Connect system, and the delta between the two is relatively small. But that delta makes a big difference, and OpenID Connect manages to avoid many of the pitfalls discussed above by adding several key components to the OAuth base: [...]
The document then goes on to describe (among other things) token IDs and a UserInfo endpoint. The former provides a set of claims (who you are, when the token was issued, etc, and possibly a signature to verify the authenticity of the token via a published public key without having to ask the upstream service), and the latter provides a means of e.g. asking for the user's first/last name, email, and similar bits of info, all in a standardized way (as opposed to the ad-hoc extensions to OAuth that people used before OpenID Connect standardized things).

We can force vbscript always run with 32 bit mode by changing "system32" to "sysWOW64" in default value of key "Computer\HKLM\SOFTWARE]\Classes\VBSFile\Shell\Open\Command"
There is something very important about this thread that has been touched on but not fully explained. The HTML approach (adding a meta tag in the head) only works consistently on raw HTML or very basic server pages. My site is a very complex server-driven site with master pages, themeing and a lot of third party controls, etc. What I found was that some of these controls were programmatically adding their own tags to the final HTML which were being pushed to the browser at the beginning of the head tag. This effectively rendered the HTML meta tags useless.
Well, if you can't beat them, join them. The only solution that worked for me is to do exactly the same thing in the pre-render event of my master pages as such:
Private Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender
Dim MetaTag As HtmlMeta = New HtmlMeta()
MetaTag.Attributes("http-equiv") = "Content-Type"
MetaTag.Attributes("content") = "text/html; charset=utf-8;"
Page.Header.Controls.AddAt(0, MetaTag)
MetaTag = New HtmlMeta()
MetaTag.Attributes("http-equiv") = "X-UA-Compatible"
MetaTag.Attributes("content") = "IE=9,chrome=1"
Page.Header.Controls.AddAt(0, MetaTag)
End Sub
This is VB.NET but the same approach would work for any server-side technology. As long as you make sure it's the last thing that gets done right before the page is rendered.
<script>
//$(document).ready(function () {
function showcontent() {
document.getElementById("demo22").innerHTML = "Hello World";
}
//});// end of ready function
</script>
I had the same problem where onclick function calls would not work. I had included the function inside the usual "$(document).ready(function(){});" block used to wrap jquery scripts. Commenting this block out solved the problem.
You should not use overly complex Regex (if you can avoid them) because they are
Although there might be a small performance overhead in using many small regular expressions, the points above outweight it easily.
I would implement like this:
bool matchesPolicy(pwd) {
if (pwd.length < 8) return false;
if (not pwd =~ /[0-9]/) return false;
if (not pwd =~ /[a-z]/) return false;
if (not pwd =~ /[A-Z]/) return false;
if (not pwd =~ /[%@$^]/) return false;
if (pwd =~ /\s/) return false;
return true;
}
You can use the -quit
option of find
:
find <dir> -maxdepth 1 -type d -name '*foo*' -print -quit
For t-SQL I use the following query for varchar columns (shows the collation and is_null properties):
SELECT
s.name
, o.name as table_name
, c.name as column_name
, t.name as type
, c.max_length
, c.collation_name
, c.is_nullable
FROM
sys.columns c
INNER JOIN sys.objects o ON (o.object_id = c.object_id)
INNER JOIN sys.schemas s ON (s.schema_id = o.schema_id)
INNER JOIN sys.types t ON (t.user_type_id = c.user_type_id)
WHERE
s.name = 'dbo'
AND t.name IN ('varchar') -- , 'char', 'nvarchar', 'nchar')
ORDER BY
o.name, c.name
You can use something like this:
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class testHashes {
public static void main(String args[]){
Map<String,String> myMap1 = new HashMap<String, String>();
List<Map<String , String>> myMap = new ArrayList<Map<String,String>>();
myMap1.put("URL", "Val0");
myMap1.put("CRC", "Vla1");
myMap1.put("SIZE", "Val2");
myMap1.put("PROGRESS", "Val3");
myMap.add(0,myMap1);
myMap.add(1,myMap1);
for (Map<String, String> map : myMap) {
System.out.println(map.get("URL"));
System.out.println(map.get("CRC"));
System.out.println(map.get("SIZE"));
System.out.println(map.get("PROGRESS"));
}
//System.out.println(myMap);
}
}
You can also plot the timestamp, value pairs using pyplot.plot (after parsing them from their string representation). (Tested with matplotlib versions 1.2.0 and 1.3.1.)
Example:
import datetime
import random
import matplotlib.pyplot as plt
# make up some data
x = [datetime.datetime.now() + datetime.timedelta(hours=i) for i in range(12)]
y = [i+random.gauss(0,1) for i,_ in enumerate(x)]
# plot
plt.plot(x,y)
# beautify the x-labels
plt.gcf().autofmt_xdate()
plt.show()
Resulting image:
Here's the same as a scatter plot:
import datetime
import random
import matplotlib.pyplot as plt
# make up some data
x = [datetime.datetime.now() + datetime.timedelta(hours=i) for i in range(12)]
y = [i+random.gauss(0,1) for i,_ in enumerate(x)]
# plot
plt.scatter(x,y)
# beautify the x-labels
plt.gcf().autofmt_xdate()
plt.show()
Produces an image similar to this:
Flexbox spec editor here.
This is an encouraged use of flexbox, but there are a few things you should tweak for best behavior.
Don't use prefixes. Unprefixed flexbox is well-supported across most browsers. Always start with unprefixed, and only add prefixes if necessary to support it.
Since your header and footer aren't meant to flex, they should both have flex: none;
set on them. Right now you have a similar behavior due to some overlapping effects, but you shouldn't rely on that unless you want to accidentally confuse yourself later. (Default is flex:0 1 auto
, so they start at their auto height and can shrink but not grow, but they're also overflow:visible
by default, which triggers their default min-height:auto
to prevent them from shrinking at all. If you ever set an overflow
on them, the behavior of min-height:auto
changes (switching to zero rather than min-content) and they'll suddenly get squished by the extra-tall <article>
element.)
You can simplify the <article>
flex
too - just set flex: 1;
and you'll be good to go. Try to stick with the common values in https://drafts.csswg.org/css-flexbox/#flex-common unless you have a good reason to do something more complicated - they're easier to read and cover most of the behaviors you'll want to invoke.
I use this:
Thread closeActivity = new Thread(new Runnable() {
@Override
public void run() {
try {
Thread.sleep(3000);
// Do some stuff
} catch (Exception e) {
e.getLocalizedMessage();
}
}
});
All the answers are way too long. The easiest way to add border radius to a table element that accepts border as a property, is doing border radius with overflow: hidden.
border: xStyle xColor xSize;
border-collapse: collapse;
border-radius: 1em;
overflow: hidden;
There is also an 'E' status
E = File existed before update
This can happen if you have manually created a folder that would have been created by performing an update.
Best way is to have a contextual action bar with listview on multiselect, You can make listview as multiselect using the following code
listview.setChoiceMode(AbsListView.CHOICE_MODE_MULTIPLE_MODAL);
And now set multichoice listener for Listview ,You can see the complete implementation of multiselect listview at Android multi select listview

I do not know "right" solution but I can suggest you a fast patch.
String.format("%16s", Integer.toBinaryString(1)).replace(" ", "0");
I have just tried it and saw that it works fine.
rootView
is just a view pointing to my root view in this case a relative layout
:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/addresses_confirm_root_view"
android:background="@color/WHITE_CLR">
RelativeLayout rootView = (RelativeLayout) findViewById(R.id.addresses_confirm_root_view);
getViewTreeObserver()
rootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
int heightDiff = rootView.getRootView().getHeight() - rootView.getHeight();
if (heightDiff > 100) { // Value should be less than keyboard's height
Log.e("MyActivity", "keyboard opened");
} else {
Log.e("MyActivity", "keyboard closed");
}
}
});
I am not sure what you really want here. If you want to see the .NET framework source code, you may try Netmassdownloader. It's free.
If you want to see any assembly's code (not just .NET), you can use ReSharper. Although it's not free.
You can also do this with the ol' good method :
String inputLine = "test123";
String translatedString = null;
char[] stringArray = inputLine.toCharArray();
for(int i=0;i<stringArray.length;i++){
translatedString += Integer.toBinaryString((int) stringArray[i]);
}
I want to present performance of different approaches, on Python 3.4, Linux x64. Excerpt from line profiler:
Line # Hits Time Per Hit % Time Line Contents
==============================================================
(...)
823 1508 11334 7.5 41.6 yday = int(period_end.strftime('%j'))
824 1508 2492 1.7 9.1 yday = period_end.toordinal() - date(period_end.year, 1, 1).toordinal() + 1
825 1508 1852 1.2 6.8 yday = (period_end - date(period_end.year, 1, 1)).days + 1
826 1508 5078 3.4 18.6 yday = period_end.timetuple().tm_yday
(...)
So most efficient is
yday = (period_end - date(period_end.year, 1, 1)).days
Note:drawRect
and fillRect
are different.
Draws the outline of the specified rectangle:
public void drawRect(int x,
int y,
int width,
int height)
Fills the specified rectangle. The rectangle is filled using the graphics context's current color:
public abstract void fillRect(int x,
int y,
int width,
int height)
In addition to existing good answers, note that Jackson 1.9 improved handling by adding "property unification", meaning that ALL annotations from difference parts of a logical property are combined, using (hopefully) intuitive precedence.
In Jackson 1.8 and prior, only field and getter annotations were used when determining what and how to serialize (writing JSON); and only and setter annotations for deserialization (reading JSON). This sometimes required addition of "extra" annotations, like annotating both getter and setter.
With Jackson 1.9 and above these extra annotations are NOT needed. It is still possible to add those; and if different names are used, one can create "split" properties (serializing using one name, deserializing using other): this is occasionally useful for sort of renaming.
assuming certain column names...
INSERT one
newToner = Toner(toner_id = 1,
toner_color = 'blue',
toner_hex = '#0F85FF')
dbsession.add(newToner)
dbsession.commit()
INSERT multiple
newToner1 = Toner(toner_id = 1,
toner_color = 'blue',
toner_hex = '#0F85FF')
newToner2 = Toner(toner_id = 2,
toner_color = 'red',
toner_hex = '#F01731')
dbsession.add_all([newToner1, newToner2])
dbsession.commit()
UPDATE
q = dbsession.query(Toner)
q = q.filter(Toner.toner_id==1)
record = q.one()
record.toner_color = 'Azure Radiance'
dbsession.commit()
or using a fancy one-liner using MERGE
record = dbsession.merge(Toner( **kwargs))
This worked for me:
RewriteCond %{HTTPS} =off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [QSA,L,R=301]
I had the same problem and it was because my reference to the jQuery.js was not in the tag. Once I switched that, everything started working.

Example from MVC 4 for dropdownlist validation on Submit using Dataannotation and ViewBag (less line of code)
Models:
namespace Project.Models
{
public class EmployeeReferral : Person
{
public int EmployeeReferralId { get; set; }
//Company District
//List
[Required(ErrorMessage = "Required.")]
[Display(Name = "Employee District:")]
public int? DistrictId { get; set; }
public virtual District District { get; set; }
}
namespace Project.Models
{
public class District
{
public int? DistrictId { get; set; }
[Display(Name = "Employee District:")]
public string DistrictName { get; set; }
}
}
EmployeeReferral Controller:
namespace Project.Controllers
{
public class EmployeeReferralController : Controller
{
private ProjDbContext db = new ProjDbContext();
//
// GET: /EmployeeReferral/
public ActionResult Index()
{
return View();
}
public ActionResult Create()
{
ViewBag.Districts = db.Districts;
return View();
}
View:
<td>
<div class="editor-label">
@Html.LabelFor(model => model.DistrictId, "District")
</div>
</td>
<td>
<div class="editor-field">
@*@Html.DropDownList("DistrictId", "----Select ---")*@
@Html.DropDownListFor(model => model.DistrictId, new SelectList(ViewBag.Districts, "DistrictId", "DistrictName"), "--- Select ---")
@Html.ValidationMessageFor(model => model.DistrictId)
</div>
</td>
Why can't we use ViewBag for populating dropdownlists that can be validated with Annotations. It is less lines of code.
Directory Services/LDAP lookups can be used to serve this purpose. It involves some changes at infrastructure level, but most production environments have such provision
For anyone else that reads this!!!!
HEIGHT is defined as the number of nodes in the longest path from the root node to a leaf node. Therefore: a tree with only a root node has a height of 1 and not 0.
The LEVEL of a given node is the distance from the root plus 1. Therefore: The root is on level 1, its child nodes are on level 2 and so on.

this should work:
private void cleanlistbox(object sender, EventArgs e)

listBox1.Items.Clear( );
}
You're passing the result of somedict.keys()
to the function. In Python 3, dict.keys
doesn't return a list, but a set-like object that represents a view of the dictionary's keys and (being set-like) doesn't support indexing.
To fix the problem, use list(somedict.keys())
to collect the keys, and work with that.
How many characters can a type text field store?
According to Documentation You can use maximum of 21,844 characters if the charset is UTF8
If a lot, would I be able to specify length in the db text type field as I would with varchar?
You dont need to specify the length. If you need more character use data types MEDIUMTEXT or LONGTEXT. With VARCHAR, specifieng length is not for Storage requirement, it is only for how the data is retrieved from data base.
Well, given your constraints, I think setting overflow: scroll;
on the .page
div is probably your only option. 280 px is pretty narrow, and given your font size, word wrapping alone isn't going to do it. Some words are just long and can't be wrapped. You can either reduce your font size drastically or go with overflow: scroll.
Its simple: In appsettings.json
"MyValues": {
"Value1": "Xyz"
}
In .cs file:
static IConfiguration conf = (new ConfigurationBuilder().SetBasePath(Directory.GetCurrentDirectory()).AddJsonFile("appsettings.json").Build());
public static string myValue1= conf["MyValues:Value1"].ToString();
The problem still not resolved after remove the '.', then it start points the error to my folder. As i added this folder first time then i restarted the PyCharm and it automatically resolved the issue

Login into your server using a shell program like putty.
Type in the following command on the command line
zcat DB_File_Name.sql.gz | mysql -u username -p Target_DB_Name
where
DB_File_Name.sql.gz
= full path of the sql.gz file to be imported
username
= your mysql username
Target_DB_Name
= database name where you want to import the database
When you hit enter in the command line, it will prompt for password. Enter your MySQL password.
You are done!

I think you have a couple of options here.
you could store the last Exception in the Session and retrieve it from your custom error page; or you could just redirect to your custom error page within the Application_error event. If you choose the latter, you want to make sure you use the Server.Transfer method.
If you are concerned about the file's content being served rather than its output. You can use a double extension like: file.inc.php
. It then serves the same purpose of helpfulness and maintainability.
I normally have 2 php files for each page on my site:
welcome.php
in the root folder, containing all of the HTML markup. welcome.inc.php
in the inc
folder, containing all PHP functions specific to the welcome.php
page.EDIT: Another benefit of using the double extention .inc.php
would be that any IDE can still recognise the file as PHP code.
Your item
variable holds Array
instance (in [hash_key, hash_value]
format), so it doesn't expect Symbol
in []
method.
This is how you could do it using Hash#each
:
def format(hash)
output = Hash.new
hash.each do |key, value|
output[key] = cleanup(value)
end
output
end
or, without this:
def format(hash)
output = hash.dup
output[:company_name] = cleanup(output[:company_name])
output[:street] = cleanup(output[:street])
output
end

You have a training data which you shuffle and pick mini-batches from it. When you adjust your weights and biases using one mini-batch, you have completed one iteration. Once you run out of your mini-batches, you have completed an epoch. Then you shuffle your training data again, pick your mini-batches again, and iterate through all of them again. That would be your second epoch.
playing with globals() makes it possible:
import random
alphabet = tuple('abcdefghijklmnopqrstuvwxyz')
print '\n'.join(repr(u) for u in globals() if not u.startswith('__'))
for i in xrange(8):
globals()[''.join(random.sample(alphabet,random.randint(3,26)))] = random.choice(alphabet)
print
print '\n'.join(repr((u,globals()[u])) for u in globals() if not u.startswith('__'))
one result:
'alphabet'
'random'
('hadmgoixzkcptsbwjfyrelvnqu', 'h')
('nzklv', 'o')
('alphabet', ('a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'))

I used random because you don't explain which names of "variables" to give, and which values to create. Because i don't think it's possible to create a name without making it binded to an object.
Jon Skeet is correct. Here is the Nul Device Driver page in the Windows Embedded documentation (I have no idea why it's not somewhere else...).
Here is another:
Your question is not very clear.
You say you get a null-pointer. You cannot get a null pointer as a value returned by contains()
.
However you can get a NullPointerException
if your list has not been initialized. By reading your question now, I'd say that what you show here is correct, but maybe you just didn't instantiate the list.
For this to work (to add a feed URL if it isn't already in the list):
if (!this.rssFeedURLs.contains(rssFeedURL)) {
this.rssFeedURLs.add(rssFeedUrl);
}
then this declaration would do:
private ArrayList<String> rssFeedURLs = new ArrayList<String>();
or initialize your list later on, but before trying to access its methods:
rssFeedUrls = new ArrayList<String>();
Finally... Do you really need a List
? Maybe a Set
would be better if you don't want duplicates. Use a LinkedHashSet
if preserving the ordering matters.
Just fixed this issue. import c2 or import numpy was not working. Uninstalled the most current version of numpy. Tried to install numpy==1.15.2 just like specified above, did not work. Tried numpy==1.19.3 IT worked. I guess not all versions work perfectly with all versions of python and dependencies. So keep uninstalling and install one that works.
Mike, I had the same problem with SSIS in SQL Server 2005... Apparently, the DataFlowDestination object will always attempt to validate the data coming in, into Unicode. Go to that object, Advanced Editor, Component Properties pane, change the "ValidateExternalMetaData" property to False. Now, go to the Input and Output Properties pane, Destination Input, External Columns - set each column Data type and Length to match the database table it's going to. Now, when you close that editor, those column changes will be saved and not validated over, and it will work.

After some research and testing, I found that I had some misunderstandings about the lifetime of Docker containers. Simply restarting a container doesn't make Docker use a new image, when the image was rebuilt in the meantime. Instead, Docker is fetching the image only before creating the container. So the state after running a container is persistent.
Therefore, rebuilding and restarting isn't enough. I thought containers works like a service: Stopping the service, do your changes, restart it and they would apply. That was my biggest mistake.
Because containers are permanent, you have to remove them using docker rm <ContainerName>
first. After a container is removed, you can't simply start it by docker start
. This has to be done using docker run
, which itself uses the latest image for creating a new container-instance.
With this knowledge, it's comprehensible why storing data in containers is qualified as bad practice and Docker recommends data volumes/mounting host directorys instead: Since a container has to be destroyed to update applications, the stored data inside would be lost too. This cause extra work to shutdown services, backup data and so on.
So it's a smart solution to exclude those data completely from the container: We don't have to worry about our data, when its stored safely on the host and the container only holds the application itself.
-rf
may not really help youThe docker run
command, has a Clean up switch called -rf
. It will stop the behavior of keeping docker containers permanently. Using -rf
, Docker will destroy the container after it has been exited. But this switch has two problems:
-d
switchWhile the -rf
switch is a good option to save work during development for quick tests, it's less suitable in production. Especially because of the missing option to run a container in the background, which would mostly be required.
We can bypass those limitations by simply removing the container:
docker rm --force <ContainerName>
The --force
(or -f
) switch which use SIGKILL on running containers. Instead, you could also stop the container before:
docker stop <ContainerName>
docker rm <ContainerName>
Both are equal. docker stop
is also using SIGTERM. But using --force
switch will shorten your script, especially when using CI servers: docker stop
throws an error if the container is not running. This would cause Jenkins and many other CI servers to consider the build wrongly as failed. To fix this, you have to check first if the container is running as I did in the question (see containerRunning
variable).
According to this new knowledge, I fixed my script in the following way:
#!/bin/bash
imageName=xx:my-image
containerName=my-container
docker build -t $imageName -f Dockerfile .
echo Delete old container...
docker rm -f $containerName
echo Run new container...
docker run -d -p 5000:5000 --name $containerName $imageName
This works perfectly :)
While the currently accepted answer was a huge help to me, I wanted to share some useful modifications that simplify the queries and also increase performance.
To handle events which recur at regular intervals, such as:
Repeat every other day
or
Repeat every week on Tuesday
You should create two tables, one called events
like this:
ID NAME
1 Sample Event
2 Another Event
And a table called events_meta
like this:
ID event_id repeat_start repeat_interval
1 1 1369008000 604800 -- Repeats every Monday after May 20th 2013
1 1 1369008000 604800 -- Also repeats every Friday after May 20th 2013
With repeat_start
being a unix timestamp date with no time (1369008000 corresponds to May 20th 2013) , and repeat_interval
an amount in seconds between intervals (604800 is 7 days).
By looping over each day in the calendar you can get repeat events using this simple query:
SELECT EV.*
FROM `events` EV
RIGHT JOIN `events_meta` EM1 ON EM1.`event_id` = EV.`id`
WHERE (( 1299736800 - repeat_start) % repeat_interval = 0 )
Just substitute in the unix-timestamp (1299736800) for each date in your calendar.
Note the use of the modulo (% sign). This symbol is like regular division, but returns the ''remainder'' instead of the quotient, and as such is 0 whenever the current date is an exact multiple of the repeat_interval from the repeat_start.
This is significantly faster than the previously suggested "meta_keys"-based answer, which was as follows:
SELECT EV.*
FROM `events` EV
RIGHT JOIN `events_meta` EM1 ON EM1.`event_id` = EV.`id`
RIGHT JOIN `events_meta` EM2 ON EM2.`meta_key` = CONCAT( 'repeat_interval_', EM1.`id` )
WHERE EM1.meta_key = 'repeat_start'
AND (
( CASE ( 1299132000 - EM1.`meta_value` )
WHEN 0
THEN 1
ELSE ( 1299132000 - EM1.`meta_value` )
END
) / EM2.`meta_value`
) = 1
If you run EXPLAIN this query, you'll note that it required the use of a join buffer:
+----+-------------+-------+--------+---------------+---------+---------+------------------+------+--------------------------------+
| id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra |
+----+-------------+-------+--------+---------------+---------+---------+------------------+------+--------------------------------+
| 1 | SIMPLE | EM1 | ALL | NULL | NULL | NULL | NULL | 2 | Using where |
| 1 | SIMPLE | EV | eq_ref | PRIMARY | PRIMARY | 4 | bcs.EM1.event_id | 1 | |
| 1 | SIMPLE | EM2 | ALL | NULL | NULL | NULL | NULL | 2 | Using where; Using join buffer |
+----+-------------+-------+--------+---------------+---------+---------+------------------+------+--------------------------------+
The solution with 1 join above requires no such buffer.
You can add support for more complex types to support these types of repeat rules:
Event A repeats every month on the 3rd of the month starting on March 3, 2011
or
Event A repeats second Friday of the month starting on March 11, 2011
Your events table can look exactly the same:
ID NAME
1 Sample Event
2 Another Event
Then to add support for these complex rules add columns to events_meta
like so:
ID event_id repeat_start repeat_interval repeat_year repeat_month repeat_day repeat_week repeat_weekday
1 1 1369008000 604800 NULL NULL NULL NULL NULL -- Repeats every Monday after May 20, 2013
1 1 1368144000 604800 NULL NULL NULL NULL NULL -- Repeats every Friday after May 10, 2013
2 2 1369008000 NULL 2013 * * 2 5 -- Repeats on Friday of the 2nd week in every month
Note that you simply need to either specify a repeat_interval
or a set of repeat_year
, repeat_month
, repeat_day
, repeat_week
, and repeat_weekday
data.
This makes selection of both types simultaneously very simple. Just loop through each day and fill in the correct values, (1370563200 for June 7th 2013, and then the year, month, day, week number and weekday as follows):
SELECT EV.*
FROM `events` EV
RIGHT JOIN `events_meta` EM1 ON EM1.`event_id` = EV.`id`
WHERE (( 1370563200 - repeat_start) % repeat_interval = 0 )
OR (
(repeat_year = 2013 OR repeat_year = '*' )
AND
(repeat_month = 6 OR repeat_month = '*' )
AND
(repeat_day = 7 OR repeat_day = '*' )
AND
(repeat_week = 2 OR repeat_week = '*' )
AND
(repeat_weekday = 5 OR repeat_weekday = '*' )
AND repeat_start <= 1370563200
)
This returns all events that repeat on the Friday of the 2nd week, as well as any events that repeat every Friday, so it returns both event ID 1 and 2:
ID NAME
1 Sample Event
2 Another Event
*Sidenote in the above SQL I used PHP Date's default weekday indexes, so "5" for Friday
Hope this helps others as much as the original answer helped me!
On bulk, you can always delete the row before the insert. A deletion of a row that doesn't exist doesn't cause an error, so its safely skipped.
A simple example:
const strArr = ["red", "green", "blue", "black"];
const strGen = function*() {
for(let str of strArr) {
yield str;
}
};
let gen = strGen();
for (let i = 0; i < 5; i++) {
console.log(gen.next())
}
//prints: {value: "red", done: false} -> 5 times with different colors, if you try it again as below:
console.log(gen.next());
//prints: {value: undefined, done: true}
As I can see the array is of String only.For each loop can be used to get individual element of the array and put them in local inner class for use.
Below is the code snippet for it :
//WorkAround
for (String color : colors ){
String pos = Character.toUpperCase(color.charAt(0)) + color.substring(1);
JMenuItem Jmi =new JMenuItem(pos);
Jmi.setIcon(new IconA(color));
Jmi.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
JMenuItem item = (JMenuItem) e.getSource();
IconA icon = (IconA) item.getIcon();
// HERE YOU USE THE String color variable and no errors!!!
Color kolorIkony = getColour(color);
textArea.setForeground(kolorIkony);
}
});
mnForeground.add(Jmi);
}
}
I had similar issue when connecting to RDS Oracle even when client and server were both set to TLSv1.2 the certs was right and java was 1.8.0_141 So Finally I had to apply patch at Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files
After applying the patch the issue went away and connection went fine.
OK, I have found the problem.
I use some reporting plugins. In the documentation of the failsafe-maven-plugin
I found, that the <encoding>
configuration - of course - uses ${project.reporting.outputEncoding}
by default.
So I added the property as a child element of the project
element and everything is fine now:
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
</properties>

remove leading or trailing characters:
function trimLeadingTrailing(inputStr, toRemove) {
// use a regex to match toRemove at the start (^)

const re = new Regex(`/^${toRemove}|{toRemove}$/`);
return inputStr.replace(re, '');
}
The accepted answer is the correct way to do this in most cases. However, there are some situations where you want to set the cookie header manually. Normally if you set a "Cookie" header it is ignored, but that's because HttpClientHandler
defaults to using its CookieContainer
property for cookies. If you disable that then by setting UseCookies
to false
you can set cookie headers manually and they will appear in the request, e.g.
var baseAddress = new Uri("http://example.com");
using (var handler = new HttpClientHandler { UseCookies = false })
using (var client = new HttpClient(handler) { BaseAddress = baseAddress })
{
var message = new HttpRequestMessage(HttpMethod.Get, "/test");
message.Headers.Add("Cookie", "cookie1=value1; cookie2=value2");
var result = await client.SendAsync(message);
result.EnsureSuccessStatusCode();
}
If you use jQuery and would need an inline solution, this would work very well;
<a href="#" onclick="$(this).closest('form').submit();">submit form</a>
Also, you might want to replace
<a href="#">text</a>
with
<a href="javascript:void(0);">text</a>
so the user does not scroll to the top of your page when clicking the link.
you need to take out the quotes:
soda = a + b
(You want to refer to the variables a
and b
, not the strings "a" and "b")
*my_map.begin()
. See e.g. http://cplusplus.com/reference/stl/map/begin/.
values() method may simply work:
for (Direction d : Direction.values()) {
//whatever you want to do with each of these enum values
}
If you want to do it typed:
class Something {
areas: Area[][];
constructor() {
this.areas = new Array<Array<Area>>();
for (let y = 0; y <= 100; y++) {
let row:Area[] = new Array<Area>();
for (let x = 0; x <=100; x++){
row.push(new Area(x, y));
}
this.areas.push(row);
}
}
}
Change draggable

You can create dispatch queue using this code in swift 3.0
DispatchQueue.main.async
{
/*Write your code here*/
}
/* or */
let delayTime = DispatchTime.now() + Double(Int64(0.5 * Double(NSEC_PER_SEC))) / Double(NSEC_PER_SEC)
DispatchQueue.main.asyncAfter(deadline: delayTime)
{
/*Write your code here*/
}
In my case I was trying to run postgres through docker. Initially I was running as :
docker run -d -p 5432:5432 -e POSTGRES_PASSWORD=test_password POSTGRES_USER=test_user POSTGRES_DB=test_db --rm -v ~/docker/volumes/postgres:/var/lib/postgresql/data --name pg-docker postgres
I was missing -e after each environment variable. Changing the above command to the one below worked
docker run -d -p 5432:5432 -e POSTGRES_PASSWORD=test_password -e POSTGRES_USER=test_user -e POSTGRES_DB=test_db --rm -v ~/docker/volumes/postgres:/var/lib/postgresql/data --name pg-docker postgres
This is my take on it:
public enum LoginState {
LOGGED_IN(1), LOGGED_OUT(0), IN_TRANSACTION(-1);
private int code;
LoginState(int code) {
this.code = code;
}
public int getCode() {
return code;
}
public static LoginState getLoginStateFromCode(int code){
for(LoginState e : LoginState.values()){
if(code == e.code) return e;
}
return LoginState.LOGGED_OUT; //or null
}
};
And I have used it with System Preferences in Android like so:
LoginState getLoginState(int i) {
return LoginState.getLoginStateFromCode(
prefs().getInt(SPK_IS_LOGIN, LoginState.LOGGED_OUT.getCode())
);
}
public static void setLoginState(LoginState newLoginState) {
editor().putInt(SPK_IS_LOGIN, newLoginState.getCode());
editor().commit();
}
where pref
and editor
are SharedPreferences
and a SharedPreferences.Editor
Rhomobile Rhodes (http://rhomobile.com/products/rhodes) is very similar in approach to PhoneGap, but is the only framework with:
ssize_t
is used for functions whose return value could either be a valid size, or a negative value to indicate an error.
It is guaranteed to be able to store values at least in the range [-1, SSIZE_MAX]
(SSIZE_MAX
is system-dependent).
So you should use size_t
whenever you mean to return a size in bytes, and ssize_t
whenever you would return either a size in bytes or a (negative) error value.

If you're using 1.9.2 or above, you can convert hashes and arrays to nested JSON objects just using to_json.
{a: [1,2,3], b: 4}.to_json
In Rails, you can call to_json on Active Record objects. You can pass :include and :only parameters to control the output:
@user.to_json only: [:name, :email]
You can also call to_json on AR relations, like so:
User.order("id DESC").limit(10).to_json
You don't need to import anything and it all works exactly as you'd hope.
A simple approach to install Maven.
Finder -> Go -> Utilities -> Terminal
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install maven
Very similar to @Jonathan Wheeler:
If you do not want to remember, but not rewrite bar
:
rm -r bar/
cp -r foo/ !$
!$
displays the last argument of your previous command.
You need to that in two steps, at least.
First, click on the ¶ symbol in the toolbar: you can see if you have CRLF
line endings or just LF
.
Click on the Replace button, and put \r\n
or \n
, depending on the kind of line ending. In the Search Mode section of the dialog, check Extended radio button (interpret \n
and such).
Then replace all occurrences with nothing (empty string).
You end with a big line...
Next, in the same Replace dialog, put your delimiter (</Row>
) for example and in the Replace With field, put the same with a line ending (</Row>\r\n
). Replace All, and you are done.
Use sudo pip3 install jupyter
for installing jupyter for python3 and sudo pip install jupyter
for installing jupyter notebook for python2. Then, you can call ipython kernel install
command to enable both types of notebook to choose from in jupyter notebook.

It seems the interface has changed in .NET 4.0. There is the following method that achieves all of the above. As Tommy Engebretsen suggested, putting it in a TextChanged event handler makes it automatic.
textBox1.ScrollToEnd();
The error is down to an "inappropriate use" of the double colon operator:
return $cnf::getConfig($key);
as by using the ::
you're attempting to call a static method of the class itself. In your example you want to call a non-static method on an instantiated object.
I think what you want is:
return $cnf->getConfig($key);
The default string representation for a dictionary seems to be just right:
>>> a={3: 'foo', 17: 'bar' }
>>> a
{17: 'bar', 3: 'foo'}
>>> print a
{17: 'bar', 3: 'foo'}
>>> print "a=", a
a= {17: 'bar', 3: 'foo'}
Not sure if you can get at the "variable name", since variables in Python are just labels for values. See this question.
You could try writing to stderr, rather than stdout.
fprintf(stderr, "Hello, please enter your age\n");
You should also have a look at this relevant thread.
Scott S's answer worked perfectly.
I was coding a web-based phone dialpad for mobile, and every time the user would press a number on the keypad (composed of td span elements in a table), the softkeyboard would pop up. I also wanted the user to not be able to tap into the input box of the number being dialed. This actually solved both problems in 1 shot. The following was used:
<input type="text" id="phone-number" onfocus="blur();" />
Suppose you bound your combobox to a List<Person>
List<Person> pp = new List<Person>();
pp.Add(new Person() {id = 1, name="Steve"});
pp.Add(new Person() {id = 2, name="Mark"});
pp.Add(new Person() {id = 3, name="Charles"});
cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;
At this point you cannot set the Text property as you like, but instead you need to add an item to your list before setting the datasource
pp.Insert(0, new Person() {id=-1, name="--SELECT--"});
cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;
cbo1.SelectedIndex = 0;
Of course this means that you need to add a checking code when you try to use the info from the combobox
if(cbo1.SelectedValue != null && Convert.ToInt32(cbo1.SelectedValue) == -1)
MessageBox.Show("Please select a person name");
else
......
The code is the same if you use a DataTable instead of a list. You need to add a fake row at the first position of the Rows collection of the datatable and set the initial index of the combobox to make things clear. The only thing you need to look at are the name of the datatable columns and which columns should contain a non null value before adding the row to the collection
In a table with three columns like ID, FirstName, LastName with ID,FirstName and LastName required you need to
DataRow row = datatable.NewRow();
row["ID"] = -1;
row["FirstName"] = "--Select--";
row["LastName"] = "FakeAddress";
dataTable.Rows.InsertAt(row, 0);
I find the accepted answer, and all the others strange, since they pass self
to an abstract class. An abstract class is not instantiated so can't have a self
.
So try this, it works.
from abc import ABCMeta, abstractmethod
class Abstract(metaclass=ABCMeta):
@staticmethod
@abstractmethod
def foo():
"""An abstract method. No need to write pass"""
class Derived(Abstract):
def foo(self):
print('Hooray!')
FOO = Derived()
FOO.foo()
An old question but worth mentioning another option in the answers. In case the DNS system of your domain has been defined in Amazon Route 53, you can use Amazon CloudFront service in front of your EC2 and attach a free Amazon SSL certificate to it. This way you will benefit from both having a CDN for a faster content delivery and also securing you domain with HTTPS protocol.
TypeScript does something similar to what less or sass does for CSS. They are super sets of it, which means that every JS code you write is valid TypeScript code. Plus you can use the other goodies that it adds to the language, and the transpiled code will be valid js. You can even set the JS version that you want your resulting code on.
Currently TypeScript is a super set of ES2015, so might be a good choice to start learning the new js features and transpile to the needed standard for your project.
In a shameless attempt to steal some votes, SecurityProtocol
is an Enum
with the [Flags]
attribute. So you can do this:
[Net.ServicePointManager]::SecurityProtocol =
[Net.SecurityProtocolType]::Tls12 -bor `
[Net.SecurityProtocolType]::Tls11 -bor `
[Net.SecurityProtocolType]::Tls
Or since this is PowerShell, you can let it parse a string for you:
[Net.ServicePointManager]::SecurityProtocol = "tls12, tls11, tls"
Then you don't technically need to know the TLS version.
I copied and pasted this from a script I created after reading this answer because I didn't want to cycle through all the available protocols to find one that worked. Of course, you could do that if you wanted to.
Final note - I have the original (minus SO edits) statement in my PowerShell profile so it's in every session I start now. It's not totally foolproof since there are still some sites that just fail but I surely see the message in question much less frequently.
Try
gdb --args InsertionSortWithErrors arg1toinsort arg2toinsort
import sys
print(sys.argv[0])
This will print foo.py
for python foo.py
, dir/foo.py
for python dir/foo.py
, etc. It's the first argument to python
. (Note that after py2exe it would be foo.exe
.)
I found the problem. This code was placed in a separate file that was added with a php include() function. And this include was happening before the Bootstrap files were loaded. So the Bootstrap JS file was not loaded yet, causing this modal to not do anything.
With the above code sample is nothing wrong and works as intended when placed in the body part of a html page.
<script type="text/javascript">
$('#memberModal').modal('show');
</script>
On limited version of Linux (like a QNAP (nas) I was working on):
grep -f file1 file2
can cause some problems as said by @ChristopherSchultz and using grep -F -f file1 file2
was really slow (more than 5 minutes - not finished it - over 2-3 seconds with the method below on files over 20MB)So here is what I did :
sort file1 > file1.sorted
sort file2 > file2.sorted
diff file1.sorted file2.sorted | grep "<" | sed 's/^< *//' > files.diff
diff file1.sorted files.diff | grep "<" | sed 's/^< *//' > files.same.sorted
If files.same.sorted
shall have been in same order than the original ones, than add this line for same order than file1 :
awk 'FNR==NR {a[$0]=$0; next}; $0 in a {print a[$0]}' files.same.sorted file1 > files.same
or, for same order than file2 :
awk 'FNR==NR {a[$0]=$0; next}; $0 in a {print a[$0]}' files.same.sorted file2 > files.same
Restarting my ng serve

why all of this location url?
http://localhost:8080/meet2eat/index.php
you can just use
index.php
if the php files are in the same folder and this is better because if you want to host the files or change the port you will have no problem reaching this URL.
Any user whose login shell setting in /etc/passwd
is an interactive shell can login. I don't think there's a totally reliable way to tell if a program is an interactive shell; checking whether it's in /etc/shells
is probably as good as you can get.
Other users can also login, but the program they run should not allow them to get much access to the system. And users that aren't allowed to login at all should have /etc/false
as their shell -- this will just log them out immediately.
The module timeit
is useful for this and is included in the standard Python distribution.
Example:
import timeit
timeit.Timer('for i in xrange(10): oct(i)').timeit()
In my opinion, two important scenarios other than stopping thread in which volatile keyword is used are:
Try this
<input type="submit"
value="HOME"
onclick="goHome()"
style="font-size : 20px; width: 100%; height: 100px;" />
Classifiers are just objects that can be pickled and dumped like any other. To continue your example:
import cPickle
# save the classifier
with open('my_dumped_classifier.pkl', 'wb') as fid:
cPickle.dump(gnb, fid)
# load it again
with open('my_dumped_classifier.pkl', 'rb') as fid:
gnb_loaded = cPickle.load(fid)
Edit: if you are using a sklearn Pipeline in which you have custom transformers that cannot be serialized by pickle (nor by joblib), then using Neuraxle's custom ML Pipeline saving is a solution where you can define your own custom step savers on a per-step basis. The savers are called for each step if defined upon saving, and otherwise joblib is used as default for steps without a saver.
Just add the directory on the command line:
svn checkout svn://192.168.1.1/projectname/ target-directory/
Below is the code to do it in vtd-xml. It basically queries the XML with the XPath of "/xml/item/@name."
import com.ximpleware.*;
public class getAttrs{
public static void main(String[] s) throws VTDException{
VTDGen vg = new VTDGen();
if (!vg.parseFile("input.xml",false)) // turn off namespace
return;
VTDNav vn = vg.getNav();
AutoPilot ap = new AutoPilot(vn);
ap.selectXPath("/xml/item/@name");
int i=0;
while( (i=ap.evalXPath())!=-1){
System.out.println(" item name is ===>"+vn.toString(i+1));
}
}
}
As of Internet Explorer 10, you can use the ::-ms-expand
pseudo element selector to style, and hide, the drop down arrow element.
select::-ms-expand {
display:none;
/* or visibility: hidden; to keep it's space/hitbox */
}
The remaining styling should be similar to other browsers.
Here is a basic fork of Danield's jsfiddle that applies support for IE10
you should precompile the regexp, if you use it repeatedly
re_ip = re.compile('\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$')
# note the terminating $ to really match only the IPs
then use
if re_ip.match(st):
print '!IP'
but.. is e.g. '111.222.333.444' really the IP?
i'd look at netaddr
or ipaddr
libraries whether they can be used to match IPs

Just reset your development and distribution certificate and clean your project. After that , Reboot also worked for me. Interestingly it seems to be an issue with allowing Xcode access to the certificates. When i tried the archive again, i received 2 popups asking me if i wanted to allow Xcode to access my keychain. After this it worked fine.
If you have multiple dialog, you can use this:
$("#the_dialog").dialog({
open: function(event, ui) {
//hide titlebar.
$(this).parent().children('.ui-dialog-titlebar').hide();
}
});
I had the same problem with selenium 2 in internet explorer 9, but my fix is really strange. I was not able to click into inputs inside my form -> selenium repeats, their are not visible.
It occured when my form had curved shadows -> http://www.paulund.co.uk/creating-different-css3-box-shadows-effects: in the concrete "Effect no. 2"
I have no idea, why&how this pseudo element solution's stopped selenium tests, but it works for me.
As the options here didn't work for me, I'm sharing how I solved it:
My project has a parent project (with its own pom.xml) that has many children modules, one of which (A) has a dependency to another child (B). When I tried mvn package
in A, it didn't work because B could not be resolved.
Executing mvn install
in the parent directory did the job. After that, I could do mvn package
inside of A and only then it could find B.
Or you can use temporary array and then delete the real one if you want to change it while in cycle:
$array = array(0 => 'a', 1 => 'b', 2 => 'c');
$temp_array = $array[1];
unset($array[1]);
array_unshift($array , $temp_array);
the output will be:
array(0 => 'b', 1 => 'a', 2 => 'c')
and when are doing it while in cycle, you should clean $temp_array
after appending item to array.
Use the Javascript string split() function.
var coolVar = '123-abc-itchy-knee';
var partsArray = coolVar.split('-');
// Will result in partsArray[0] == '123', partsArray[1] == 'abc', etc
Alternatively you could read you csv with header=None
and then add it with df.columns
:
Cov = pd.read_csv("path/to/file.txt", sep='\t', header=None)
Cov.columns = ["Sequence", "Start", "End", "Coverage"]
Admitting that I haven't tried it, the testfixtures' logging feature looks quite useful...

Your function declares a constant reference to a string:
int foo(const string &myname) {
cout << "called foo for: " << myname << endl;
return 0;
}
A reference has some special properties, which make it a safer alternative to pointers in many ways:
How does the function signature differ from the equivalent C:
int foo(const char *myname)
There are several differences, since the first refers directly to an object, while const char*
must be dereferenced to point to the data.
Is there a difference between using string *myname vs string &myname?
The main difference when dealing with parameters is that you do not need to dereference &myname
. A simpler example is:
int add_ptr(int *x, int* y)
{
return *x + *y;
}
int add_ref(int &x, int &y)
{
return x + y;
}
which do exactly the same thing. The only difference in this case is that you do not need to dereference x
and y
as they refer directly to the variables passed in.
const string &GetMethodName() { ... }
What is the & doing here? Is there some website that explains how & is used differently in C vs C++?
This returns a constant reference to a string. So the caller gets to access the returned variable directly, but only in a read-only sense. This is sometimes used to return string data members without allocating extra memory.
There are some subtleties with references - have a look at the C++ FAQ on References for some more details.
There should be templates already included in Visio 2007 for software architecture but you might want to check out Visio 2007 templates.
I think what you are looking for is:
list(im.getdata())
or, if the image is too big to load entirely into memory, so something like that:
for pixel in iter(im.getdata()):
print pixel
from PIL documentation:
getdata
im.getdata() => sequence
Returns the contents of an image as a sequence object containing pixel values. The sequence object is flattened, so that values for line one follow directly after the values of line zero, and so on.
Note that the sequence object returned by this method is an internal PIL data type, which only supports certain sequence operations, including iteration and basic sequence access. To convert it to an ordinary sequence (e.g. for printing), use list(im.getdata()).
SELECT REPLACE(CONVERT(varchar, MONTH(GetDate()) * 0.01), '0.', '')
When you specify -jar
then the -cp
parameter will be ignored.
From the documentation:
When you use this option, the JAR file is the source of all user classes, and other user class path settings are ignored.
You also cannot "include" needed jar files into another jar file (you would need to extract their contents and put the .class files into your jar file)
You have two options:
lib
directory into the manifest (you can use relative paths there)-cp
: java -cp MyJar.jar:lib/* com.somepackage.subpackage.Main
Java 8 style
JSONArray data = jsonObject.getJSONArray("some-node");
List<JSONObject> list = StreamSupport.stream(data.spliterator(), false)
.map(e -> (JSONObject)e)
.collect(Collectors.toList());
my solution works as follows:
import UIKit
class LoginViewController: UIViewController, NSURLConnectionDataDelegate {
@IBOutlet var usernameTextField: UITextField
@IBOutlet var passwordTextField: UITextField
@IBAction func login(sender: AnyObject) {
var url = NSURL(string: "YOUR_URL")
var request = NSURLRequest(URL: url)
var connection = NSURLConnection(request: request, delegate: self, startImmediately: true)
}
func connection(connection:NSURLConnection!, willSendRequestForAuthenticationChallenge challenge:NSURLAuthenticationChallenge!) {
if challenge.previousFailureCount > 1 {
} else {
let creds = NSURLCredential(user: usernameTextField.text, password: passwordTextField.text, persistence: NSURLCredentialPersistence.None)
challenge.sender.useCredential(creds, forAuthenticationChallenge: challenge)
}
}
func connection(connection:NSURLConnection!, didReceiveResponse response: NSURLResponse) {
let status = (response as NSHTTPURLResponse).statusCode
println("status code is \(status)")
// 200? Yeah authentication was successful
}
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
You can use this class as the implementation of a ViewController. Connect your fields to the IBOutlet annotated vars and your Button to the IBAction annotated function.
Explanation: In function login you create your request with NSURL, NSURLRequest and NSURLConnection. Essential here is the delegate which references to this class (self). For receiving the delegates calls you need to
Async:
fs.readFile('test.txt', 'utf8', callback);
Sync:
var content = fs.readFileSync('test.txt', 'utf8');
Numpy arrays do not have an append method. Use the Numpy append function instead:
import numpy as np
array_3 = np.append(array_1, array_2, axis=n)
# you can either specify an integer axis value n or remove the keyword argument completely
For example, if array_1 and array_2 have the following values:
array_1 = np.array([1, 2])
array_2 = np.array([3, 4])
If you call np.append without specifying an axis value, like so:
array_3 = np.append(array_1, array_2)
array_3 will have the following value:
array([1, 2, 3, 4])
Else, if you call np.append with an axis value of 0, like so:
array_3 = np.append(array_1, array_2, axis=0)
array_3 will have the following value:
array([[1, 2],
[3, 4]])
More information on the append function here: https://docs.scipy.org/doc/numpy/reference/generated/numpy.append.html
I got a better method from here: WCF: Creating Custom Headers, How To Add and Consume Those Headers
Client Identifies Itself
The goal here is to have the client provide some sort of information which the server can use to determine who is sending the message. The following C# code will add a header named ClientId:
var cl = new ActiveDirectoryClient();
var eab = new EndpointAddressBuilder(cl.Endpoint.Address);
eab.Headers.Add( AddressHeader.CreateAddressHeader("ClientId", // Header Name
string.Empty, // Namespace
"OmegaClient")); // Header Value
cl.Endpoint.Address = eab.ToEndpointAddress();
// Now do an operation provided by the service.
cl.ProcessInfo("ABC");
What that code is doing is adding an endpoint header named ClientId with a value of OmegaClient to be inserted into the soap header without a namespace.
Custom Header in Client’s Config File
There is an alternate way of doing a custom header. That can be achieved in the Xml config file of the client where all messages sent by specifying the custom header as part of the endpoint as so:
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IActiveDirectory" />
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:41863/ActiveDirectoryService.svc"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IActiveDirectory"
contract="ADService.IActiveDirectory" name="BasicHttpBinding_IActiveDirectory">
<headers>
<ClientId>Console_Client</ClientId>
</headers>
</endpoint>
</client>
</system.serviceModel>
</configuration>
As mentioned, you cannot cast it directly. One possible solution is to have those generic types inherit from a non-generic interface, in which case you can still invoke methods on it without reflection. Using reflection, you can pass the mapped object to any method expecting it, then the cast will be performed for you. So if you have a method called Accept expecting a MessageProcessor as a parameter, then you can find it and invoke it dynamically.
i encountred this problem, and after investigating my css, the main container (direct child of the body) had:
position: relative
z-index: 1
the backdrop worked well after i removed those two properties. You may also encounter this problem if the main wraper have a position: fixed
I'm lacking context, but this is working just fine:
List<BigInteger> nums = new ArrayList<BigInteger>();
Long max = Collections.max(nums).longValue(); // from BigInteger to Long...
To expound on cletus' answer, at runtime all record of the generic types is removed. Generics are processed only in the compiler and are used to provide additional type safety. They are really just shorthand that allows the compiler to insert typecasts at the appropriate places. For example, previously you'd have to do the following:
List x = new ArrayList();
x.add(new SomeClass());
Iterator i = x.iterator();
SomeClass z = (SomeClass) i.next();
becomes
List<SomeClass> x = new ArrayList<SomeClass>();
x.add(new SomeClass());
Iterator<SomeClass> i = x.iterator();
SomeClass z = i.next();
This allows the compiler to check your code at compile-time, but at runtime it still looks like the first example.
Adding to the answers above, for those who want a quick way to use an external USB device (HDD, flash drive) working inside docker, and not using priviledged mode:
Find the devpath to your device on the host:
sudo fdisk -l
You can recognize your drive by it's capacity quite easily from the list. Copy this path (for the following example it is /dev/sda2
).
Disque /dev/sda2 : 554,5 Go, 57151488 octets, 111624 secteurs
Unités : secteur de 1 × 512 = 512 octets
Taille de secteur (logique / physique) : 512 octets / 512 octets
taille d'E/S (minimale / optimale) : 512 octets / 512 octets
Mount this devpath (preferable to /media
):
sudo mount <drive path> /media/<mount folder name>
You can then use this either as a param to docker run
like:
docker run -it -v /media/<mount folder name>:/media/<mount folder name>
or in docker compose under volumes:
services:
whatevermyserviceis:
volumes:
- /media/<mount folder name>:/media/<mount folder name>
And now when you run and enter your container, you should be able to access the drive inside the container at /media/<mount folder name>
DISCLAIMER:
There are many ways to skip the first line. In addition to those said by Bakuriu, I would add:
with open(filename, 'r') as f:
next(f)
for line in f:
and:
with open(filename,'r') as f:
lines = f.readlines()[1:]
you could put the style in container div menu with:
<div style="position:relative; z-index:10">
...
<!--html menu-->
...
</div>

Like you say, you need to show some code. :-)
A stack overflow error usually happens when your function calls nest too deeply. See the Stack Overflow Code Golf thread for some examples of how this happens (though in the case of that question, the answers intentionally cause stack overflow).
Here is a two steps solution here is a hack to IE10 and 11
@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
/* IE10+ specific styles go here */
}
because IE10 and IE11 Supports -ms-high-cotrast you can take the advantage of this to target this two browsers
and if you want to exclude the IE10 from this you must create a IE10 specific code as follow it's using the user agent trick you must add this Javascript
var doc = document.documentElement;
doc.setAttribute('data-useragent', navigator.userAgent);
and this HTML tag
<html data-useragent="Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Trident/6.0)">
and now you can write your CSS code like this
html[data-useragent*='MSIE 10.0'] h1 {
color: blue;
}
for more information please refer to this websites,wil tutorail, Chris Tutorial
And if you want to target IE11 and later,here is what I've found:
_:-ms-fullscreen, :root .selector {}
Here is a great resource for getting more information: browserhacks.com
You can use:
Handler handler = new Handler()
handler.postDelayed(new Runnable())
Or you can use:
handler.removeCallbacksAndMessages(null);
Docs
public final void removeCallbacksAndMessages (Object token)
Added in API level 1 Remove any pending posts of callbacks and sent messages whose obj is token. If token is null, all callbacks and messages will be removed.
Or you could also do like the following:
Handler handler = new Handler()
Runnable myRunnable = new Runnable() {
public void run() {
// do something
}
};
handler.postDelayed(myRunnable,zeit_dauer2);
Then:
handler.removeCallbacks(myRunnable);
Docs
public final void removeCallbacks (Runnable r)
Added in API level 1 Remove any pending posts of Runnable r that are in the message queue.
public final void removeCallbacks (Runnable r, Object token)
Edit:
Change this:
@Override
public void onClick(View v) {
Handler handler = new Handler();
Runnable myRunnable = new Runnable() {
To:
@Override
public void onClick(View v) {
handler = new Handler();
myRunnable = new Runnable() { /* ... */}
Because you have the below. Declared before onCreate
but you re-declared and then initialized it in onClick
leading to a NPE.
Handler handler; // declared before onCreate
Runnable myRunnable;
In a google script project you can create html files (example: index.html) or gs files (example:code.gs). The .gs files are executed on the server and you can use Logger.log as @Peter Herrman describes. However if the function is created in a .html file it is being executed on the user's browser and you can use console.log. The Chrome browser console can be viewed by Ctrl Shift J on Windows/Linux or Cmd Opt J on Mac
If you want to use Logger.log on an html file you can use a scriptlet to call the Logger.log function from the html file. To do so you would insert <? Logger.log(something) ?> replacing something with whatever you want to log. Standard scriptlets, which use the syntax <? ... ?>, execute code without explicitly outputting content to the page.
The clue is to work with the dict's items (i.e. key-value pair tuples). Then by using the second element of the item as the max
key (as opposed to the dict
key) you can easily extract the highest value and its associated key.
mydict = {'A':4,'B':10,'C':0,'D':87}
>>> max(mydict.items(), key=lambda k: k[1])
('D', 87)
>>> min(mydict.items(), key=lambda k: k[1])
('C', 0)
I've done this before. You can just create a new exception and grab the stack trace on it without throwing it, then examine the stack trace. As the other answer says though, it's extremely costly--don't do it in a tight loop.
I've done it before for a logging utility on an app where performance didn't matter much (Performance rarely matters much at all, actually--as long as you display the result to an action such as a button click quickly).
It was before you could get the stack trace, exceptions just had .printStackTrace() so I had to redirect System.out to a stream of my own creation, then (new Exception()).printStackTrace(); Redirect System.out back and parse the stream. Fun stuff.
If you used Aptitude (apt-get) to install Jenkins on Ubuntu 12.04, uncomment the JAVA_ARGS
line in the top few lines of /etc/default/jenkins
:
# arguments to pass to java

#JAVA_ARGS="-Djava.net.preferIPv4Stack=true" # make jenkins listen on IPv4 address
I've had various problems (see below) installing upgraded SSL modules, even inside a virtualenv, on top of older OS-provided Python versions, so I now use pyenv
.
pyenv makes it very easy to install new Python versions and supports virtualenvs. Getting started is much easier than the recipes for virtualenv listed in other answers:
brew install pyenv
and on Linux, use pyenv-installerThis works very well to insulate the "new Python" version and virtualenv from system Python. Because you can easily use a more recent Python (post 2.7.9), the SSL modules are already upgraded, and of course like any modern virtualenv setup you are insulated from the system Python modules.
A couple of nice tutorials:
pyenv global 3.6.1
(global to current user) or pyenv local 2.7.13
(local to current directory).The pyenv-virtualenv
plugin is now built in - type pyenv commands | grep virtualenv
to check. I wouldn't use the pyenv-virtualenvwrapper plugin to start with - see how you get on with pyenv-virtualenv which is more integrated into pyenv, as this covers most of what virtualenvwrapper does.
pyenv
is modelled on rbenv
(a good tool for Ruby version switching) and its only dependency is bash.
pyvenv
- that is a virtualenv equivalent that's part of recent Python 3 versions, and doesn't handle Python version switchingTwo warnings about pyenv:
dash
, which is /bin/sh
on Ubuntu or Debian.bash --login
using a terminal), which is not always easy to achieve with automation tools such as Ansible.Hence pyenv is best for interactive use, and less good for scripting servers.
One reason to use pyenv
was that there were often problems with upgrading Python SSL modules when using older system-provided Python versions. This may be less of a problem now that current Linux distributions support Python 3.x.
If you want to keep the keys of the initial array and also add an array that has keys, then use the function below:
function insertArrayAtPosition( $array, $insert, $position ) {
/*
$array : The initial array i want to modify
$insert : the new array i want to add, eg array('key' => 'value') or array('value')
$position : the position where the new array will be inserted into. Please mind that arrays start at 0
*/
return array_slice($array, 0, $position, TRUE) + $insert + array_slice($array, $position, NULL, TRUE);
}
Call example:
$array = insertArrayAtPosition($array, array('key' => 'Value'), 3);

You don't need git to accomplish this. Creative use of a bash function will do the trick just fine. If you don't care about messages, just set a default one and forget it.
function gitcom() {
git commit -m "my default commit message"
}
If you were feeling really adventurous you could add, commit and push with one command
function gitzap() {
git add . && git commit -m "whatevs" && git push $1 $2
}
Which you would then run as
gitzap origin master
You could even get deeper and use parse_git_branch to save yourself some keystrokes there, or set a common default of "origin" and "master".
You could try the following:
class ResponseCodeCheck
{
public static void main (String args[]) throws Exception
{
URL url = new URL("http://google.com");
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("GET");
connection.connect();
int code = connection.getResponseCode();
System.out.println("Response code of the object is "+code);
if (code==200)
{
System.out.println("OK");
}
}
}

It should be default, but it might be hidden.
"It might be that something happened to your

You can use map
, it can map vales from a dictonairy or even a custom function.
Suppose this is your df:
ID First_Name Last_Name
0 103 a b
1 104 c d
Create the dicts:
fnames = {103: "Matt", 104: "Mr"}
lnames = {103: "Jones", 104: "X"}
And map:
df['First_Name'] = df['ID'].map(fnames)
df['Last_Name'] = df['ID'].map(lnames)
The result will be:
ID First_Name Last_Name
0 103 Matt Jones
1 104 Mr X
Or use a custom function:
names = {103: ("Matt", "Jones"), 104: ("Mr", "X")}
df['First_Name'] = df['ID'].map(lambda x: names[x][0])
x = cumsum(c(0, runif(100, -1, +1)))
y = cumsum(c(0, runif(100, -1, +1)))
fit = lm(y ~ x)

i just found this site that give a cool themes for the select box http://gregfranko.com/jquery.selectBoxIt.js/
and you can try this themes if your problem with the overall look blue - yellow - grey
This header is defined in RFC 2183, so that would be the best place to start reading.
Permitted values are those registered with the Internet Assigned Numbers Authority (IANA); their registry of values should be seen as the definitive source.
I believe it's in C:\Windows\System32\WindowsPowershell\v1.0\
. In order to confuse the innocent, MS kept it in a directory labeled "v1.0". Running this on Windows 7 and checking the version number via $Host.Version
(Determine installed PowerShell version) shows it's 2.0.
Another option is type $PSVersionTable
at the command prompt. If you are running v2.0, the output will be:
Name Value
---- -----
CLRVersion 2.0.50727.4927
BuildVersion 6.1.7600.16385
PSVersion 2.0
WSManStackVersion 2.0
PSCompatibleVersions {1.0, 2.0}
SerializationVersion 1.1.0.1
PSRemotingProtocolVersion 2.1
If you're running version 1.0, the variable doesn't exist and there will be no output.
Localization PowerShell version 1.0, 2.0, 3.0, 4.0:
To check all ports:
netstat -lnp
To close an open port:
fuser -k port_no/tcp
Example:
fuser -k 8080/tcp
In both cases you can use the sudo
command if needed.
If you want to read a CSV File with encoding utf-8, a minimalistic approach that I recommend you is to use something like this:
with open(file_name, encoding="utf8") as csv_file:
With that statement, you can use later a CSV reader to work with.
Here is one way to “untrack” any files that are would otherwise be ignored under the current set of exclude patterns:
(GIT_INDEX_FILE=some-non-existent-file \
git ls-files --exclude-standard --others --directory --ignored -z) |
xargs -0 git rm --cached -r --ignore-unmatch --
This leaves the files in your working directory but removes them from the index.
The trick used here is to provide a non-existent index file to git ls-files so that it thinks there are no tracked files. The shell code above asks for all the files that would be ignored if the index were empty and then removes them from the actual index with git rm.
After the files have been “untracked”, use git status to verify that nothing important was removed (if so adjust your exclude patterns and use git reset -- path to restore the removed index entry). Then make a new commit that leaves out the “crud”.
The “crud” will still be in any old commits. You can use git filter-branch to produce clean versions of the old commits if you really need a clean history (n.b. using git filter-branch will “rewrite history”, so it should not be undertaken lightly if you have any collaborators that have pulled any of your historical commits after the “crud” was first introduced).
use center right as the position then add a transparent border to offset it?
You could also use:
request.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
True
is 1
in Python, and likewise False
is 0
*:
>>> True == 1
True
>>> False == 0
True
You should be able to perform any operations you want on them by just treating them as though they were numbers, as they are numbers:
>>> issubclass(bool, int)
True
>>> True * 5
5
So to answer your question, no work necessary - you already have what you are looking for.
* Note I use is as an English word, not the Python keyword is
- True
will not be the same object as any random 1
.
Simply use this in Objective-C to dismiss keyboard:
[[UIApplication sharedApplication].keyWindow endEditing:YES];
Try using the TimeRange object in C# to complete your goal.
TimeRange timeRange = new TimeRange();
timeRange = TimeRange.Parse("13:00-14:00");
bool IsNowInTheRange = timeRange.IsIn(DateTime.Now.TimeOfDay);
Console.Write(IsNowInTheRange);
Those are all ways to start the standard minecraft launcher with those credentials in the text boxes.
There used to be a way to login to minecraft without the launcher using the command line, but it has since been patched.
If you want to make a custom launcher using the command line then good luck, the only way to login to the minecraft jar(IE: the way the launcher does it) is to send a post request to https://login.minecraft.net/ with the username,password,launcher version, and a RSA key. It then parses the pseudo Json, and uses the session token from that to authenticate the jar from the command line with a load of arguments.
If you are trying to make a minecraft launcher and you have no knowledge of java,http requests or json then you have no chance.
Swift
It's the identifier for your current session in PHP. If you delete it, you won't be able to access/make use of session variables. I'd suggest you keep it.
Generalized:
char* subString (const char* input, int offset, int len, char* dest)
{
int input_len = strlen (input);
if (offset + len > input_len)
{
return NULL;
}
strncpy (dest, input + offset, len);
return dest;
}
char dest[80];
const char* source = "hello world";
if (subString (source, 0, 5, dest))
{
printf ("%s\n", dest);
}
show variables where Variable_name='hostname';
That could help you !!
Before 3.2.6, Mongodb does not support join query as like mysql. below solution which works for you.
db.getCollection('comments').aggregate([
{$match : {pid : 444}},
{$lookup: {from: "users",localField: "uid",foreignField: "uid",as: "userData"}},
])
It worked for me for most of the viewcontrollers.
self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false
It wasn't not working for some viewcontrollers like UIPageViewController. On UIPageViewController's pagecontentviewcontroller below code worked for me.
override func viewDidLoad() {
self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false
self.navigationController?.interactivePopGestureRecognizer?.delegate = self
}
override func viewWillDisappear(_ animated: Bool) {
self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false
self.navigationController?.interactivePopGestureRecognizer?.delegate = nil
}
On UIGestureRecognizerDelegate,
func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
if gestureRecognizer == self.navigationController?.interactivePopGestureRecognizer {
return false
}
return true
}
var hoverAndClick = function() {
// Your actions here
} ;
$("#target").hover( hoverAndClick ).click( hoverAndClick ) ;
This is because the CHARINDEX-1 is returning a -ive value if the look-up for " " (space) is 0. The simplest solution would be to avoid '-ve' by adding
ABS(CHARINDEX(' ', PostCode ) -1))
which will return only +ive values for your length even if CHARINDEX(' ', PostCode ) -1)
is a -ve value. Correct me if I'm wrong!
If, like me, you use Spyder IDE, you have to disable the interactive mode with :
plt.ioff()
(this command is automatically launched with the scientific startup)
If you want to enable it again, use :
plt.ion()
If you installed the command line tools separately, delete them using:
sudo rm -rf /Library/Developer/CommandLineTools
Ask the person maintaining the server at http://172.16.1.157:8002/ to add your hostname to Access-Control-Allow-Origin hosts, the server should return a header similar to the following with the response-
Access-Control-Allow-Origin: yourhostname:port
Sure. Assuming you have a string with the file's name called fname
, the following does the trick.
with open(fname, 'r') as fin:
print(fin.read())
If you have
char[] c
then you can do
char* d = &c[0]
and access element c[1] by doing *(d+1)
, etc.
You can try this
String text = "ddd123.0114cc";
String numOnly = text.replaceAll("\\p{Alpha}","");
try {
double numVal = Double.valueOf(numOnly);
System.out.println(text +" contains numbers");
} catch (NumberFormatException e){
System.out.println(text+" not contains numbers");
}
For mongoDB 3.0, You will have to set the following in the config file.
logpath=E:\mongoDBdata\log\mongoDB.log
dbpath=E:\mongoDBdata\db
the logpath should end with a file and not a folder.
This is the correct and easiest way to accomplish this for 95% of use cases:
>>> df = pd.DataFrame(zip(*[range(10)]), columns=['num'])
>>> df
num
0 0
1 1
2 2
3 3
4 4
5 5
>>> def example(x):
... x['p1'] = x['num']**2
... x['p2'] = x['num']**3
... x['p3'] = x['num']**4
... return x
>>> df = df.apply(example, axis=1)
>>> df
num p1 p2 p3
0 0 0 0 0
1 1 1 1 1
2 2 4 8 16
3 3 9 27 81
4 4 16 64 256
What about npm i -g npm
? Did you try to run this as well?
A lookahead regex syntax can help you to achieve your goal. Thus a regex for your example is
.*?quick.*?(?=z)
And it's important to notice the .*?
lazy matching before the (?=z)
lookahead: the expression matches a substring until a first occurrence of the z
letter.
Here is C# code sample:
const string text = "The quick red fox jumped over the lazy brown dogz";
string lazy = new Regex(".*?quick.*?(?=z)").Match(text).Value;
Console.WriteLine(lazy); // The quick red fox jumped over the la
string greedy = new Regex(".*?quick.*(?=z)").Match(text).Value;
Console.WriteLine(greedy); // The quick red fox jumped over the lazy brown dog
In XAMPP installation directory, open %XAMPP_HOME%/php/php.ini
file. Uncomment the following line:
extension=php_curl.dll
PS: If that doesn't work then check whether %XAMPP_HOME%/php/ext/php_curl.dll
file exist or not.
I suggest you to do:
chmod 400 ~/.ssh/id_rsa
It works fine for me.
If you want to run a Python subprocess under the virtualenv, you can do that by running the script using the Python interpreter that lives inside virtualenv's /bin/ directory:
import subprocess
# Path to a Python interpreter that runs any Python script
# under the virtualenv /path/to/virtualenv/
python_bin = "/path/to/virtualenv/bin/python"
# Path to the script that must run under the virtualenv
script_file = "must/run/under/virtualenv/script.py"
subprocess.Popen([python_bin, script_file])
However, if you want to activate the virtualenv under the current Python interpreter instead of a subprocess, you can use the activate_this.py
script:
# Doing execfile() on this file will alter the current interpreter's
# environment so you can import libraries in the virtualenv
activate_this_file = "/path/to/virtualenv/bin/activate_this.py"
execfile(activate_this_file, dict(__file__=activate_this_file))
It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment
to your bean.
@Autowired
private Environment environment;
....
this.environment.getActiveProfiles();
much simpler code:
import java.util.Arrays; int[][] array = new int[][];
Arrays.sort(array, ( a, b) -> a[1] - b[1]);
Since Java 1.6, a java.exe is installed into %windir%\system32 that supports a "-version" command line option. You can use this to select a specific version to run, e.g.:
java -version:1.7 -jar [path to jar file]
will run a jar application in java 1.7, if it is installed.

As an extension of @Demyn's answer, I created some utility functions which print the current function's name and current function's arguments:
import inspect
import logging
import traceback
def get_function_name():
return traceback.extract_stack(None, 2)[0][2]
def get_function_parameters_and_values():
frame = inspect.currentframe().f_back
args, _, _, values = inspect.getargvalues(frame)
return ([(i, values[i]) for i in args])
def my_func(a, b, c=None):
logging.info('Running ' + get_function_name() + '(' + str(get_function_parameters_and_values()) +')')
pass
logger = logging.getLogger()
handler = logging.StreamHandler()
formatter = logging.Formatter(
'%(asctime)s [%(levelname)s] -> %(message)s')
handler.setFormatter(formatter)
logger.addHandler(handler)
logger.setLevel(logging.INFO)
my_func(1, 3) # 2016-03-25 17:16:06,927 [INFO] -> Running my_func([('a', 1), ('b', 3), ('c', None)])
Try "perldoc -l":
$ perldoc -l Log::Dispatch /usr/local/share/perl/5.26.1/Log/Dispatch.pm
First, exend JFrame properly with a super() and a constructor then add actionlisteners to the frame and add the buttons.
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
public class Calc extends JFrame implements ActionListener {
JButton button1 = new JButton("1");
JButton button2 = new JButton("2");
public Calc()
{
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(100, 100);
button1.addActionListener(this);
button2.addActionListener(this);
calcFrame.add(button1);
calcFrame.add(button2);
}
public void actionPerformed(ActionEvent e)
{
Object source = e.getSource();
if(source == button1)
{
\\button1 code here
} else if(source == button2)
{
\\button2 code here
}
}
public static void main(String[] args)
{
JFrame calcFrame = new JFrame();
calcFrame.setVisible(true);
}
}
