Set up a virtualenv:
% curl -kLso /tmp/get-pip.py https://bootstrap.pypa.io/get-pip.py
% sudo python /tmp/get-pip.py
These commands install pip into the global site-packages directory.
% sudo pip install virtualenv
and ditto for virtualenv:
% mkdir -p ~/.virtualenvs
I like my virtualenvs under one tree in my home directory called .virtualenvs
% virtualenv ~/.virtualenvs/lxmltest
Creates a virtualenv.
% . ~/.virtualenvs/lxmltest/bin/activate
Removes the need to specify the full path to pip/python in this virtualenv.
% pip install lxml
Alternatively execute ~/.virtualenvs/lxmltest/bin/pip install lxml
if you chose not to follow the previous step. Note, I'm not sure how far along you are, so some of these steps can be safely skipped. Of course, if you mess something up, you can always rm -Rf ~/.virtualenvs/lxmltest
and start again from a new virtualenv.
New, detailed answer and explanation to an old, frequently asked question...
Short answer: If you don't add elementFormDefault="qualified"
to xsd:schema
, then the default unqualified
value means that locally declared elements are in no namespace.
There's a lot of confusion regarding what elementFormDefault
does, but this can be quickly clarified with a short example...
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:target="http://www.levijackson.net/web340/ns"
targetNamespace="http://www.levijackson.net/web340/ns">
<element name="assignments">
<complexType>
<sequence>
<element name="assignment" type="target:assignmentInfo"
minOccurs="1" maxOccurs="unbounded"/>
</sequence>
</complexType>
</element>
<complexType name="assignmentInfo">
<sequence>
<element name="name" type="string"/>
</sequence>
<attribute name="id" type="string" use="required"/>
</complexType>
</schema>
Key points:
assignment
element is locally defined.elementFormDefault
is unqualified
.elementFormDefault="qualified"
so that assignment
is in the target namespace as one would
expect.form
attribute on xs:element
declarations for which elementFormDefault
establishes default values.This XML looks like it should be valid according to the above XSD:
<assignments xmlns="http://www.levijackson.net/web340/ns"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.levijackson.net/web340/ns try.xsd">
<assignment id="a1">
<name>John</name>
</assignment>
</assignments>
Notice:
assignments
places assignments
and all of its descendents in the default namespace (http://www.levijackson.net/web340/ns
).Despite looking valid, the above XML yields the following confusing validation error:
[Error] try.xml:4:23: cvc-complex-type.2.4.a: Invalid content was found starting with element 'assignment'. One of '{assignment}' is expected.
Notes:
assignment
element but it actually found an assignment
element. (WTF){
and }
around assignment
means that validation was expecting assignment
in no namespace here. Unfortunately, when it says that it found an assignment
element, it doesn't mention that it found it in a default namespace which differs from no namespace.elementFormDefault="qualified"
to the xsd:schema
element of the XSD. This means valid XML must place elements in the target namespace when locally declared in the XSD; otherwise, valid XML must place locally declared elements in no namespace.assignment
be in no namespace. This can be achieved,
for example, by adding xmlns=""
to the assignment
element.Credits: Thanks to Michael Kay for helpful feedback on this answer.
Maybe not as clean or efficient as the already posted solutions, but how about the .each() function? E.g:
var mvar = "";
$(".mbox").each(function() {
console.log($(this).html());
mvar += $(this).html();
});
console.log(mvar);
Try this:
// this will fix old browsers
if (!Array.prototype.indexOf) {
Array.prototype.indexOf = function(value) {
for (var i = 0; i < this.length; i++) {
if (this[i] === value) {
return i;
}
}
return -1;
}
}
// example
if ([1, 2, 3].indexOf(2) != -1) {
// yay!
}
Here i want to show my code how i managed this.
public class CheckPermission {
public Context context;
public static final int PERMISSION_REQUEST_CODE = 200;
public CheckPermission(Context context){
this.context = context;
}
public boolean isPermissionGranted(){
int read_contact = ContextCompat.checkSelfPermission(context.getApplicationContext() , READ_CONTACTS);
int phone = ContextCompat.checkSelfPermission(context.getApplicationContext() , CALL_PHONE);
return read_contact == PackageManager.PERMISSION_GRANTED && phone == PackageManager.PERMISSION_GRANTED;
}
}
Here in this class i want to check permission granted or not. Is not then i will call permission from my MainActivity like
public void requestForPermission() {
ActivityCompat.requestPermissions(MainActivity.this, new String[] {READ_CONTACTS, CALL_PHONE}, PERMISSION_REQUEST_CODE);
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case PERMISSION_REQUEST_CODE:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (shouldShowRequestPermissionRationale(ACCESS_FINE_LOCATION)) {
showMessageOKCancel("You need to allow access to both the permissions",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(new String[]{Manifest.permission.READ_CONTACTS, Manifest.permission.CALL_PHONE},
PERMISSION_REQUEST_CODE);
}
}
});
return;
}
}
}
}
Now in the onCreate method you need to call requestForPermission() function.
That's it.Also you can request multiple permission at a time.
You can also use:
.rhead {
width:300px;
}
but this will only with with some browsers, if I remember correctly IE8 does not allow this. Over all, It is safer to just put the width=""
attribute in the <td>
itself.
I think this is easier:
double time = 200.3456;
DecimalFormat df = new DecimalFormat("#.##");
time = Double.valueOf(df.format(time));
System.out.println(time); // 200.35
Note that this will actually do the rounding for you, not just formatting.
psql -U postgres
Worked fine for me in case of db name: postgres & username: postgres. So you do not need to write sudo.
And in the case other db, you may try
psql -U yourdb postgres
As it is given in Postgres help:
psql [OPTION]... [DBNAME [USERNAME]]

I would recommend the use of IPNetwork Library https://github.com/lduchosal/ipnetwork. As of version 2, it supports IPv4 and IPv6 as well.
IPv4
IPNetwork ipnetwork = IPNetwork.Parse("192.168.0.1/25");
Console.WriteLine("Network : {0}", ipnetwork.Network);
Console.WriteLine("Netmask : {0}", ipnetwork.Netmask);
Console.WriteLine("Broadcast : {0}", ipnetwork.Broadcast);
Console.WriteLine("FirstUsable : {0}", ipnetwork.FirstUsable);
Console.WriteLine("LastUsable : {0}", ipnetwork.LastUsable);
Console.WriteLine("Usable : {0}", ipnetwork.Usable);
Console.WriteLine("Cidr : {0}", ipnetwork.Cidr);
Output
Network : 192.168.0.0
Netmask : 255.255.255.128
Broadcast : 192.168.0.127
FirstUsable : 192.168.0.1
LastUsable : 192.168.0.126
Usable : 126
Cidr : 25
Have fun !
I may be misunderstanding your question but it seems you should just be able to use a relative path as long as the production and development servers use the same path structure.

Use LOWER function to convert the strings to lower case before comparing.
Try this:

There is something called 'locked reference' in excel which you can use for this, and you use $
symbols to lock a range. For your example, you would use:
=IF(B4<>"",B4/B$1,"")
This locks the 1
in B1
so that when you copy it to rows below, 1
will remain the same.
If you use $B$1
, the range will not change when you copy it down a row or across a column.
For me the solution was fixing a syntax error:
removing a unwanted semi colon in the angular.module function

I believe you need to .f
file as a parameter, not as a command-single-string. same with the "--domain "+i
, which i would split in two elements of the list.
Assuming that:
FORTRAN
executable, ~/
is indeed the correct way for the FORTRAN
executableI would change this line:
subprocess.Popen(["FORTRAN ~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f", "--domain "+i])
to
subprocess.Popen(["FORTRAN", "~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f", "--domain", i])
If that doesn't work, you should do a os.path.exists()
for the .f
file, and check that you can launch the FORTRAN
executable without any path, and set the path or system path variable accordingly
[EDIT 6-Mar-2017]
As the exception, detailed in the original post, is a python exception from subprocess
; it is likely that the WinError 2
is because it cannot find FORTRAN
I highly suggest that you specify full path for your executable:
for i in input:
exe = r'c:\somedir\fortrandir\fortran.exe'
fortran_script = r'~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f'
subprocess.Popen([exe, fortran_script, "--domain", i])
if you need to convert the forward-slashes to backward-slashes, as suggested in one of the comments, you can do this:
for i in input:
exe = os.path.normcase(r'c:\somedir\fortrandir\fortran.exe')
fortran_script = os.path.normcase(r'~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f')
i = os.path.normcase(i)
subprocess.Popen([exe, fortran_script, "--domain", i])
[EDIT 7-Mar-2017]
The following line is incorrect:
exe = os.path.normcase(r'~/C:/Program Files (x86)/Silverfrost/ftn95.exe'
I am not sure why you have ~/
as a prefix for every path, don't do that.
for i in input:
exe = os.path.normcase(r'C:/Program Files (x86)/Silverfrost/ftn95.exe'
fortran_script = os.path.normcase(r'C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f')
i = os.path.normcase(i)
subprocess.Popen([exe, fortran_script, "--domain", i])
[2nd EDIT 7-Mar-2017]
I do not know this FORTRAN or ftn95.exe, does it need a shell to function properly?, in which case you need to launch as follows:
subprocess.Popen([exe, fortran_script, "--domain", i], shell = True)
You really need to try to launch the command manually from the working directory which your python script is operating from. Once you have the command which is actually working, then build up the subprocess
command.
I realize this is an older thread, but for future reference:
As of iPhone SDK 3.0, custom gradients can be implemented very easily, without subclassing or images, by using the new CAGradientLayer
:
UIView *view = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 100)] autorelease];
CAGradientLayer *gradient = [CAGradientLayer layer];
gradient.frame = view.bounds;
gradient.colors = [NSArray arrayWithObjects:(id)[[UIColor blackColor] CGColor], (id)[[UIColor whiteColor] CGColor], nil];
[view.layer insertSublayer:gradient atIndex:0];
Take a look at the CAGradientLayer docs. You can optionally specify start and end points (in case you don't want a linear gradient that goes straight from the top to the bottom), or even specific locations that map to each of the colors.
I think there are three key items you need to understand regarding project structure: Targets, projects, and workspaces. Targets specify in detail how a product/binary (i.e., an application or library) is built. They include build settings, such as compiler and linker flags, and they define which files (source code and resources) actually belong to a product. When you build/run, you always select one specific target.
It is likely that you have a few targets that share code and resources. These different targets can be slightly different versions of an app (iPad/iPhone, different brandings,…) or test cases that naturally need to access the same source files as the app. All these related targets can be grouped in a project. While the project contains the files from all its targets, each target picks its own subset of relevant files. The same goes for build settings: You can define default project-wide settings in the project, but if one of your targets needs different settings, you can always override them there:
Shared project settings that all targets inherit, unless they override it
Concrete target settings: PSE iPhone overrides the project’s Base SDK
setting
In Xcode, you always open projects (or workspaces, but not targets), and all the targets it contains can be built/run, but there’s no way/definition of building a project, so every project needs at least one target in order to be more than just a collection of files and settings.
Select one of the project’s targets to run
In a lot of cases, projects are all you need. If you have a dependency that you build from source, you can embed it as a subproject. Subprojects can be opened separately or within their super project.
demoLib is a subproject
If you add one of the subproject’s targets to the super project’s dependencies, the subproject will be automatically built unless it has remained unchanged. The advantage here is that you can edit files from both your project and your dependencies in the same Xcode window, and when you build/run, you can select from the project’s and its subprojects’ targets:
If, however, your library (the subproject) is used by a variety of other projects (or their targets, to be precise), it makes sense to put it on the same hierarchy level – that’s what workspaces are for. Workspaces contain and manage projects, and all the projects it includes directly (i.e., not their subprojects) are on the same level and their targets can depend on each other (projects’ targets can depend on subprojects’ targets, but not vice versa).
Workspace structure
In this example, both apps (AnotherApplication / ProjectStructureExample) can reference the demoLib project’s targets. This would also be possible by including the demoLib project in both other projects as a subproject (which is a reference only, so no duplication necessary), but if you have lots of cross-dependencies, workspaces make more sense. If you open a workspace, you can choose from all projects’ targets when building/running.
You can still open your project files separately, but it is likely their targets won’t build because Xcode cannot resolve the dependencies unless you open the workspace file. Workspaces give you the same benefit as subprojects: Once a dependency changes, Xcode will rebuild it to make sure it’s up-to-date (although I have had some issues with that, it doesn’t seem to work reliably).
Your questions in a nutshell:
1) Projects contain files (code/resouces), settings, and targets that build products from those files and settings. Workspaces contain projects which can reference each other.
2) Both are responsible for structuring your overall project, but on different levels.
3) I think projects are sufficient in most cases. Don’t use workspaces unless there’s a specific reason. Plus, you can always embed your project in a workspace later.
4) I think that’s what the above text is for…
There’s one remark for 3): CocoaPods, which automatically handles 3rd party libraries for you, uses workspaces. Therefore, you have to use them, too, when you use CocoaPods
(which a lot of people do).
Your action method considers model type asList<string>
. But, in your view you are waiting for IEnumerable<Standings.Models.Teams>
.
You can solve this problem with changing the model in your view to List<string>
.
But, the best approach would be to return IEnumerable<Standings.Models.Teams>
as a model from your action method. Then you haven't to change model type in your view.
But, in my opinion your models are not correctly implemented. I suggest you to change it as:
public class Team
{
public int Position { get; set; }
public string HomeGround {get; set;}
public string NickName {get; set;}
public int Founded { get; set; }
public string Name { get; set; }
}
Then you must change your action method as:
public ActionResult Index()
{
var model = new List<Team>();
model.Add(new Team { Name = "MU"});
model.Add(new Team { Name = "Chelsea"});
...
return View(model);
}
And, your view:
@model IEnumerable<Standings.Models.Team>
@{
ViewBag.Title = "Standings";
}
@foreach (var item in Model)
{
<div>
@item.Name
<hr />
</div>
}

If you want to convert back the file formats which have been changed to UNIX Format from PC format.
(1)You need to reinstall tortoise GIT and in the "Line Ending Conversion" Section make sure that you have selected "Check out as is - Check in as is"option.
(2)and keep the remaining configurations as it is.
(3)once installation is done
(4)write all the file extensions which are converted to UNIX format into a text file (extensions.txt).
ex:*.dsp
*.dsw
(5) copy the file into your clone Run the following command in GITBASH
while read -r a;
do
find . -type f -name "$a" -exec dos2unix {} \;

As my purpose is to get an empty version of the test database to import data from an external previous current active source (Access database) once all is fine tuned. I found that using DBCC CloneDatabase with Verify_CloneDB option fits perfectly.
So try this out (x == true) ^ (x == false)
note you need the parenthesis but this is more beautiful and compact.
It even passes the suggested like "cuak" but not a "cuak"... class X; def !; self end end ; x = X.new; (x == true) ^ (x == false)
Note: See that this is so basic that you can use it in other languages too, that doesn't provide a "thing is boolean".
Note 2: Also you can use this to say thing is one of??: "red", "green", "blue"
if you add more XORS
... or say this thing is one of??: 4, 5, 8, 35

Safely copy a SQLite database
It's trivially easy to copy a SQLite database. It's less trivial to do this in a way that won't corrupt it. Here's how:
shell$ sqlite3 some.db sqlite> begin immediate; <press CTRL+Z> shell$ cp some.db some.db.backup shell$ exit sqlite> rollback;
This will give you a nice clean backup that's sure to be in a proper state, since writing to the database half-way through your copying process is impossible.

This may be overkill for a simple breadcrumb, but it's worth a shot. I remember having this issue a long time ago when I first started, but I never really solved it. That is, until I just decided to write this up now. :)
I have documented as best I can inline, at the bottom are 3 possible use cases. Enjoy! (feel free to ask any questions you may have)
<?php
// This function will take $_SERVER['REQUEST_URI'] and build a breadcrumb based on the user's current path
function breadcrumbs($separator = ' » ', $home = 'Home') {
// This gets the REQUEST_URI (/path/to/file.php), splits the string (using '/') into an array, and then filters out any empty values
$path = array_filter(explode('/', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)));
// This will build our "base URL" ... Also accounts for HTTPS :)
$base = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/';
// Initialize a temporary array with our breadcrumbs. (starting with our home page, which I'm assuming will be the base URL)
$breadcrumbs = Array("<a href=\"$base\">$home</a>");
// Find out the index for the last value in our path array
$last = end(array_keys($path));
// Build the rest of the breadcrumbs
foreach ($path AS $x => $crumb) {
// Our "title" is the text that will be displayed (strip out .php and turn '_' into a space)
$title = ucwords(str_replace(Array('.php', '_'), Array('', ' '), $crumb));
// If we are not on the last index, then display an <a> tag
if ($x != $last)
$breadcrumbs[] = "<a href=\"$base$crumb\">$title</a>";
// Otherwise, just display the title (minus)
else
$breadcrumbs[] = $title;
}
// Build our temporary array (pieces of bread) into one big string :)
return implode($separator, $breadcrumbs);
}
?>
<p><?= breadcrumbs() ?></p>
<p><?= breadcrumbs(' > ') ?></p>

This might be like resurrecting a dead horse. But just so it's out there, the reason why the answer to these types of questions to simply put dll's into the system32 folder is because that folder is in the os's system path.
It's actually best practice to provide the os with a path link.
With windows 10
I just had a similar situation and was looking for a solution that allows me to return an alternative default value without taking care of it at the caller side every time I need it. What we usually do in case Linq does not support what we want, is to write a new extension that takes care of it. That´s what I did. Here is what I came up with (not tested though):
public static class EnumerableExtensions
{
public static T FirstOrDefault<T>(this IEnumerable<T> items, T defaultValue)
{
foreach (var item in items)
{
return item;
}
return defaultValue;
}
public static T FirstOrDefault<T>(this IEnumerable<T> items, Func<T, bool> predicate, T defaultValue)
{
return items.Where(predicate).FirstOrDefault(defaultValue);
}
public static T LastOrDefault<T>(this IEnumerable<T> items, T defaultValue)
{
return items.Reverse().FirstOrDefault(defaultValue);
}
public static T LastOrDefault<T>(this IEnumerable<T> items, Func<T, bool> predicate, T defaultValue)
{
return items.Where(predicate).LastOrDefault(defaultValue);
}
}
Simply find the first instance where the index of the object (counting from the left) does not equal the index of the object (counting from the right).
arr.detect {|e| arr.rindex(e) != arr.index(e) }
If there are no duplicates, the return value will be nil.
I believe this is the fastest solution posted in the thread so far, as well, since it doesn't rely on the creation of additional objects, and #index
and #rindex
are implemented in C. The big-O runtime is N^2 and thus slower than Sergio's, but the wall time could be much faster due to the the fact that the "slow" parts run in C.
For email templates, inline CSS is the properly used method to style:

</tr>

If you would like to work with a textbox, be aware that setting the TextMode property to "Date" will not work on Internet Explorer 11, because it does not currently support the "Date", "DateTime", nor "Time" values.
This example illustrates how to implement it using a textbox, including validation of the dates (since the user could enter just numbers). It will work on Internet Explorer 11 as well other web browsers.

It is not certain that any global ECMAScript variables have been exported and html/css does not necessarily indicate React. So look in the .js.
Method 1: Look in ECMAScript:
The version number is exported by both modules react-dom and react but those names are often removed by bundling and the version hidden inside an execution context that cannot be accessed. A clever break point may reveal the value directly, or you can search the ECMAScript:
Method 2: Use a DOM breakpoint:
Inspect Element
Elements
paneBreak On… - subtree modifications
Sources
paneCall Stack
sub-panerender
entry, this is ReactDOM.render
render
, ie. the code that invokes renderreact-dom
module exports object
version: "15.6.2"
, ie. all values exported by react-dom
The version is also injected into React dev tools, but as far as I know not displayed anywhere.
What about
$.ajax({
type: 'POST',
url: $("form").attr("action"),
data: $("form").serialize(),
//or your custom data either as object {foo: "bar", ...} or foo=bar&...
success: function(response) { ... },
});
Depending on the schema/account you are using to connect to the database, I would suspect you are missing a grant to the account you are using to connect to the database.
Connect as PCT account in the database, then grant the account you are using select access for the table.
grant select on pi_int to Account_used_to_connect
Avoiding redundancy I don't repeat my answer here again.
Please refer to my answer here. (note that answer only covers compiling to python bytecode.)
Disable the fields and then enable them before the form is submitted:
jQuery code:
jQuery(function ($) {
$('form').bind('submit', function () {
$(this).find(':input').prop('disabled', false);
});
});
I would first create a DataTable
with the columns that you require, then populate it via Linq-to-XML.
You could use a Select query to create an object that represents each row, then use the standard approach for creating DataRows for each item ...
class Quest
{
public string Answer1;
public string Answer2;
public string Answer3;
public string Answer4;
}
public static void Main()
{
var doc = XDocument.Load("filename.xml");
var rows = doc.Descendants("QuestId").Select(el => new Quest
{
Answer1 = el.Element("Answer1").Value,
Answer2 = el.Element("Answer2").Value,
Answer3 = el.Element("Answer3").Value,
Answer4 = el.Element("Answer4").Value,
});
// iterate over the rows and add to DataTable ...
}
Steps to perform the task:
First, download and install the compiler.
Then, type the C/C++ program and save it.
Then, open the command line and change directory to the particular one where the source file is stored, using cd
like so:
cd C:\Documents and Settings\...
Then, to compile, type in the command prompt:
gcc sourcefile_name.c -o outputfile.exe
Finally, to run the code, type:
outputfile.exe
Thought this might help to someone, it happens because "When the number of data queries is greater than 1".reference
The question is clear but the title is not as precise as it could be. My answer is for those who came looking to change the axis label, as opposed to the tick labels, which is what the accepted answer is about. (The title has now been corrected).
for ax in plt.gcf().axes:
plt.sca(ax)
plt.xlabel(ax.get_xlabel(), rotation=90)
This is the best way to do it, very simple.
$msg = "Hello this is a string";
$first_index_of_i = stripos($msg,'i');
$last_index_of_i = strripos($msg, 'i');
echo "First i : " . $first_index_of_i . PHP_EOL ."Last i : " . $last_index_of_i;
Interfaces can not be directly instantiated, you should instantiate classes that implements such Interfaces.
Try this:
NameValuePair[] params = new BasicNameValuePair[] {
new BasicNameValuePair("param1", param1),
new BasicNameValuePair("param2", param2),
};
Like this:
>>> structTime = time.localtime()
>>> datetime.datetime(*structTime[:6])
datetime.datetime(2009, 11, 8, 20, 32, 35)
Since -f
caused another problem, I developed another solution.
The -f
flag does not solved my problem because my onbuild
image looks for a file in a folder and had to call like this:
-f foo/bar/Dockerfile foo/bar
instead of
-f foo/bar/Dockerfile .
Also note that this is only solution for some cases as -f
flag
Another option I like, which can be generalized once I start seeing the code not conform to DRY, is to use one controller that redirects to another controller.
public ActionResult ClientIdSearch(int cid)
{
var action = String.Format("Details/{0}", cid);
return RedirectToAction(action, "Accounts");
}
I find this allows me to apply my logic in one location and re-use it without have to sprinkle JavaScript in the views to handle this. And, as I mentioned I can then refactor for re-use as I see this getting abused.
Add a width to the .child
elements. I personally would use percentages on the margin-left
if you want to have it always 4 per row.
.child {
display: inline-block;
background: blue;
margin: 10px 0 0 2%;
flex-grow: 1;
height: 100px;
width: calc(100% * (1/4) - 10px - 1px);
}
You can use this:
df.dropna(subset=['EPS'], how='all', inplace=True)
How much a stack can grow?
You can use a VM option named ss
to adjust the maximum stack size. A VM option is usually passed using -X{option}. So you can use java -Xss1M
to set the maximum of stack size to 1M.
Each thread has at least one stack. Some Java Virtual Machines(JVM) put Java stack(Java method calls) and native stack(Native method calls in VM) into one stack, and perform stack unwinding using a Managed to Native Frame, known as M2NFrame. Some JVMs keep two stacks separately. The Xss
set the size of the Java Stack in most cases.
For many JVMs, they put different default values for stack size on different platforms.
Can we limit this growth?
When a method call occurs, a new stack frame will be created on the stack of that thread. The stack will contain local variables, parameters, return address, etc. In java, you can never put an object on stack, only object reference can be stored on stack. Since array is also an object in java, arrays are also not stored on stack. So, if you reduce the amount of your local primitive variables, parameters by grouping them into objects, you can reduce the space on stack. Actually, the fact that we cannot explicitly put objects on java stack affects the performance some time(cache miss).
Does stack has some default minimum value or default maximum value?
As I said before, different VMs are different, and may change over versions. See here.
how does garbage collection work on stack?
Garbage collections in Java is a hot topic. Garbage collection aims to collect unreachable objects in the heap. So that needs a definition of 'reachable.' Everything on the stack constitutes part of the root set references in GC. Everything that is reachable from every stack of every thread should be considered as live. There are some other root set references, like Thread objects and some class objects.
This is only a very vague use of stack on GC. Currently most JVMs are using a generational GC. This article gives brief introduction about Java GC. And recently I read a very good article talking about the GC on .net. The GC on oracle jvm is quite similar so I think that might also help you.
I typically perform the validation on the client side:
<asp:checkbox id="chkTerms" text=" I agree to the terms" ValidationGroup="vg" runat="Server" />
<asp:CustomValidator id="vTerms"
ClientValidationFunction="validateTerms"
ErrorMessage="<br/>Terms and Conditions are required."
ForeColor="Red"
Display="Static"
EnableClientScript="true"
ValidationGroup="vg"
runat="server"/>
<asp:Button ID="btnSubmit" OnClick="btnSubmit_Click" CausesValidation="true" Text="Submit" ValidationGroup="vg" runat="server" />
<script>
function validateTerms(source, arguments) {
var $c = $('#<%= chkTerms.ClientID %>');
if($c.prop("checked")){
arguments.IsValid = true;
} else {
arguments.IsValid = false;
}
}
</script>
Normally jQuery selectors do not search within the "text nodes" in the DOM. However if you use the .contents() function, text nodes will be included, then you can use the nodeType property to filter only the text nodes, and the nodeValue property to search the text string.
$('*', 'body') .andSelf() .contents() .filter(function(){ return this.nodeType === 3; }) .filter(function(){ // Only match when contains 'simple string' anywhere in the text return this.nodeValue.indexOf('simple string') != -1; }) .each(function(){ // Do something with this.nodeValue });
I know it's a late answer, but I think this is what OP asked for.
myobj[Object.keys(myobj)[0]];
from datetime import date
def d(s):
[month, day, year] = map(int, s.split('/'))
return date(year, month, day)
def days(start, end):
return (d(end) - d(start)).days
print days('8/18/2008', '9/26/2008')
This assumes, of course, that you've already verified that your dates are in the format r'\d+/\d+/\d+'
.
If you use the static method and load the properties file from the classpath folder so you can use the below code :
//load a properties file from class path, inside static method
Properties prop = new Properties();
prop.load(Classname.class.getClassLoader().getResourceAsStream("foo.properties"));
You will need two things. The first is @media screen
to activate the specific code at a certain screen size, used for responsive design. The second is the use of the visibility: hidden
attribute. Once the browser/screen reaches 600pixels then #title_message
will become hidden.
@media screen and (max-width: 600px) {
#title_message {
visibility: hidden;
clear: both;
float: left;
margin: 10px auto 5px 20px;
width: 28%;
display: none;
}
}
EDIT: if you are using another CSS for mobile then just add the visibility: hidden;
to #title_message
. Hope this helps you!
So with the code you have provided.
var bytes = Convert.FromBase64String(resizeImage.Content);
using (var imageFile = new FileStream(filePath, FileMode.Create))
{
imageFile.Write(bytes ,0, bytes.Length);
imageFile.Flush();
}
Java also does not use line numbers, which is a necessity for a GOTO function. Unlike C/C++, Java does not have goto statement, but java supports label. The only place where a label is useful in Java is right before nested loop statements. We can specify label name with break to break out a specific outer loop.
You need to provide an IFormatProvider:
@String.Format(new CultureInfo("en-US"), "{0:C}", @price)

I recommend to use bellow formula suggested on Apache:
MaxClients = (total RAM - RAM for OS - RAM for external programs) / (RAM per httpd process)
Find my script here which is running on Rhel 6.7. you can made change according to your OS.

#echo "total_httpd_processes_size=$total_httpd_processes_size"
total_http_processes_count=`ps -ylC httpd --sort:rss | wc -l`
echo "total_http_processes_count=$total_http_processes_count"
AVG_httpd_process_size=$(expr $total_httpd_processes_size / $total_http_processes_count)
echo "AVG_httpd_process_size=$AVG_httpd_process_size"
total_httpd_process_size_MB=$(expr $AVG_httpd_process_size / 1024)

total_pttpd_used_size=$(expr $total_httpd_processes_size / 1024)
echo "total_pttpd_used_size=$total_pttpd_used_size"
total_RAM_size=`free -m |grep Mem |awk '{print $2}'`

No, you can't do this in Java. Aside from anything else, d
would then presumably be an instance of A
(given the normal idea of "extends"), but users who only knew about A
wouldn't know about it - which defeats the point of an enum being a well-known set of values.
If you could tell us more about how you want to use this, we could potentially suggest alternative solutions.
new way to do it in rails 3.1 is SomeModel.limit(5).order('id desc')
If you are using Kotlin, you can define an extension function for DatePicker
:
fun DatePicker.getDate(): Date {
val calendar = Calendar.getInstance()
calendar.set(year, month, dayOfMonth)
return calendar.time
}
Then, it's just: datePicker.getDate()
. As if it had always existed.
You can use stri_paste

Hope this is helpful!
First, the class << foo
syntax opens up foo
's singleton class (eigenclass). This allows you to specialise the behaviour of methods called on that specific object.
a = 'foo'
class << a
def inspect
'"bar"'
end
end
a.inspect # => "bar"
a = 'foo' # new object, new singleton class
a.inspect # => "foo"
Now, to answer the question: class << self
opens up self
's singleton class, so that methods can be redefined for the current self
object (which inside a class or module body is the class or module itself). Usually, this is used to define class/module ("static") methods:
class String
class << self
def value_of obj
obj.to_s
end
end
end
String.value_of 42 # => "42"
This can also be written as a shorthand:
class String
def self.value_of obj
obj.to_s
end
end
Or even shorter:
def String.value_of obj
obj.to_s
end
When inside a function definition, self
refers to the object the function is being called with. In this case, class << self
opens the singleton class for that object; one use of that is to implement a poor man's state machine:
class StateMachineExample
def process obj
process_hook obj
end
private
def process_state_1 obj
# ...
class << self
alias process_hook process_state_2
end
end
def process_state_2 obj
# ...
class << self
alias process_hook process_state_1
end
end
# Set up initial state
alias process_hook process_state_1
end
So, in the example above, each instance of StateMachineExample
has process_hook
aliased to process_state_1
, but note how in the latter, it can redefine process_hook
(for self
only, not affecting other StateMachineExample
instances) to process_state_2
. So, each time a caller calls the process
method (which calls the redefinable process_hook
), the behaviour changes depending on what state it's in.

Try this. Hope it works.
1: In bash, $!
holds the PID of the last background process that was executed. That will tell you what process to monitor, anyway.
4: wait <n>
waits until the process with PID <n>
is complete (it will block until the process completes, so you might not want to call this until you are sure the process is done), and then returns the exit code of the completed process.
2, 3: ps
or ps | grep " $! "
can tell you whether the process is still running. It is up to you how to understand the output and decide how close it is to finishing. (ps | grep
isn't idiot-proof. If you have time you can come up with a more robust way to tell whether the process is still running).
Here's a skeleton script:
# simulate a long process that will have an identifiable exit code
(sleep 15 ; /bin/false) &
my_pid=$!
while ps | grep " $my_pid " # might also need | grep -v grep here
do
echo $my_pid is still in the ps output. Must still be running.
sleep 3
done
echo Oh, it looks like the process is done.
wait $my_pid
# The variable $? always holds the exit code of the last command to finish.
# Here it holds the exit code of $my_pid, since wait exits with that code.
my_status=$?
echo The exit status of the process was $my_status

I ended up getting the Eltima USB to Ethernet software working after finally giving up on the possibility of a direct to device connection over TCP. I have pretty much decided that it is not possible to connect to a device across the network only an emulator.
Based on @Chand answer. This is the implementation in Typescript. A bit safer than coercing types in JS. If you remove the type annotation should be valid JS. Also using new string functions to normalise the time.
function displayTime(millisec: number) {
const normalizeTime = (time: string): string => (time.length === 1) ? time.padStart(2, '0') : time;
let seconds: string = (millisec / 1000).toFixed(0);
let minutes: string = Math.floor(parseInt(seconds) / 60).toString();
let hours: string = '';
if (parseInt(minutes) > 59) {
hours = normalizeTime(Math.floor(parseInt(minutes) / 60).toString());
minutes = normalizeTime((parseInt(minutes) - (parseInt(hours) * 60)).toString());
}
seconds = normalizeTime(Math.floor(parseInt(seconds) % 60).toString());
if (hours !== '') {
return `${hours}:${minutes}:${seconds}`;
}
return `${minutes}:${seconds}`;
}
I am a little late, but if you like fluent interface you might design your setters for chained calls like this:
type myType struct {
s string
a, b int
}
func New(s string, err *error) *myType {
if s == "" {
*err = errors.New(
"Mandatory argument `s` must not be empty!")
}
return &myType{s: s}
}
func (this *myType) setA (a int, err *error) *myType {
if *err == nil {
if a == 42 {
*err = errors.New("42 is not the answer!")
} else {
this.a = a
}
}
return this
}
func (this *myType) setB (b int, _ *error) *myType {
this.b = b
return this
}
And then call it like this:
func main() {
var err error = nil
instance :=
New("hello", &err).
setA(1, &err).
setB(2, &err)
if err != nil {
fmt.Println("Failed: ", err)
} else {
fmt.Println(instance)
}
}
This is similar to the Functional options idiom presented on @Ripounet answer and enjoys the same benefits but has some drawbacks:
err
variable and zeroing it.There is, however, a possible small advantage, this type of function calls should be easier for the compiler to inline but I am really not a specialist.
You might want to start with scapy.
I prefer to turn the tibble to data.frame. It shows everything and you're done

Note that neither DBCC DROPCLEANBUFFERS;
nor DBCC FREEPROCCACHE;
is supported in SQL Azure / SQL Data Warehouse.
However, if you need to reset the plan cache in SQL Azure, you can alter one of the tables in the query (for instance, just add then remove a column), this will have the side-effect of removing the plan from the cache.
I personally do this as a way of testing query performance without having to deal with cached plans.
I'm not exactly sure how cordova works, but once the licenses are accepted it creates a file. You could create that file manually. It is described on this question, but here's the commands to create the required license file.

echo -e "\n8933bad161af4178b1185d1a37fbf41ea5269c55" > "$ANDROID_HOME/licenses/android-sdk-license"
Windows:
mkdir "%ANDROID_HOME%\licenses"

"FetchType.LAZY
" will only fire for primary table. If in your code you call any other method that has a parent table dependency then it will fire query to get that table information. (FIRES MULTIPLE SELECT)
"FetchType.EAGER
" will create join of all table including relevant parent tables directly. (USES JOIN
)
When to Use:
Suppose you compulsorily need to use dependant parent table informartion then choose FetchType.EAGER
.
If you only need information for certain records then use FetchType.LAZY
.
Remember, FetchType.LAZY
needs an active db session factory at the place in your code where if you choose to retrieve parent table information.
E.g. for LAZY
:
.. Place fetched from db from your dao loayer
.. only place table information retrieved
.. some code
.. getCity() method called... Here db request will be fired to get city table info

I just needed to set the size of one textbox on one page. Coding attributes on the model and creating custom editor templates were overkill, so I just wrapped the @Html.EditorFor call with a span tag that called a class which specifies the size of the textbox.
.SpaceAvailableSearch input
{
width:25px;
}
<span class="SpaceAvailableSearch">@Html.EditorFor(model => model.SearchForm.SpaceAvailable)</span>
Python assert is basically a debugging aid which test condition for internal self-check of your code. Assert makes debugging really easy when your code gets into impossible edge cases. Assert check those impossible cases.
Let's say there is a function to calculate price of item after discount :
def calculate_discount(price, discount):
discounted_price = price - [discount*price]
assert 0 <= discounted_price <= price
return discounted_price
here, discounted_price can never be less than 0 and greater than actual price. So, in case the above condition is violated assert raises an Assertion Error, which helps the developer to identify that something impossible had happened.
Hope it helps :)
You can see that your locks are pretty much working as you are using them, if you slow down the process and make them block a bit more. You had the right idea, where you surround critical pieces of code with the lock. Here is a small adjustment to your example to show you how each waits on the other to release the lock.
import threading
import time
import inspect
class Thread(threading.Thread):
def __init__(self, t, *args):
threading.Thread.__init__(self, target=t, args=args)
self.start()
count = 0
lock = threading.Lock()
def incre():
global count
caller = inspect.getouterframes(inspect.currentframe())[1][3]
print "Inside %s()" % caller
print "Acquiring lock"
with lock:
print "Lock Acquired"
count += 1
time.sleep(2)
def bye():
while count < 5:
incre()
def hello_there():
while count < 5:
incre()
def main():
hello = Thread(hello_there)
goodbye = Thread(bye)
if __name__ == '__main__':
main()
Sample output:
...
Inside hello_there()
Acquiring lock
Lock Acquired
Inside bye()
Acquiring lock
Lock Acquired
...
If you are using numpy you can use np.argsort
to get the sorted indices and apply those indices to the list. This works for any number of list that you would want to sort.
import numpy as np
arr1 = np.array([4,3,1,32,21])
arr2 = arr1 * 10
sorted_idxs = np.argsort(arr1)
print(sorted_idxs)
>>> array([2, 1, 0, 4, 3])
print(arr1[sorted_idxs])
>>> array([ 1, 3, 4, 21, 32])
print(arr2[sorted_idxs])
>>> array([ 10, 30, 40, 210, 320])
I need to do something like this I ended up going with the following solution.
I have a specific website URL that will open a page with two buttons
1) Button One go to website
2) Button Two go to application (iphone / android phone / tablet) you can fall back to a default location from here if the app is not installed (like another url or an app store)
3) cookie to remember users choice
<head>
<title>Mobile Router Example </title>
<script type="text/javascript">
function set_cookie(name,value)
{
// js code to write cookie
}
function read_cookie(name) {
// jsCode to read cookie
}
function goToApp(appLocation) {
setTimeout(function() {
window.location = appLocation;
//this is a fallback if the app is not installed. Could direct to an app store or a website telling user how to get app
}, 25);
window.location = "custom-uri://AppShouldListenForThis";
}
function goToWeb(webLocation) {
window.location = webLocation;
}
if (readCookie('appLinkIgnoreWeb') == 'true' ) {
goToWeb('http://somewebsite');
}
else if (readCookie('appLinkIgnoreApp') == 'true') {
goToApp('http://fallbackLocation');
}

Do you mean how long is the array itself, or how many customerids are in it?
Because the answer to the first question is easy: 5 (or if you don't want to hard-code it, Ben Stott's answer).
But the answer to the other question cannot be automatically determined. Presumably you have allocated an array of length 5, but will initially have 0 customer IDs in there, and will put them in one at a time, and your question is, "how many customer IDs have I put into the array?"
C can't tell you this. You will need to keep a separate variable, int numCustIds
(for example). Every time you put a customer ID into the array, increment that variable. Then you can tell how many you have put in.
@Marcin: awk example non-greedy:
awk '{if ($0 ~ /Start pattern/) {triggered=1;}if (triggered) {print; if ($0 ~ /End pattern/) { exit;}}}' filename
I know this is an old question I thought I might just add my 2 cents.
If you have a List<Something>[]
you can join them using Aggregate
public List<TType> Concat<TType>(params List<TType>[] lists)
{
var result = lists.Aggregate(new List<TType>(), (x, y) => x.Concat(y).ToList());
return result;
}
Hope this helps.
Another option is Sheet1.Rows(x & ":" & Sheet1.Rows.Count).ClearContents
(or .Clear
). The reason you might want to use this method instead of .Delete
is because any cells with dependencies in the deleted range (e.g. formulas that refer to those cells, even if empty) will end up showing #REF
. This method will preserve formula references to the cleared cells.
./main.go (in package main)
./a/a.go (in package a)
./a/b.go (in package a)
in this case:
main.go import "./a"
It can call the function in the a.go and b.go,that with first letter caps on.
The sqlalchemy docs have a writeup on the performance of various techniques that can be used for bulk inserts:
ORMs are basically not intended for high-performance bulk inserts - this is the whole reason SQLAlchemy offers the Core in addition to the ORM as a first-class component.
For the use case of fast bulk inserts, the SQL generation and execution system that the ORM builds on top of is part of the Core. Using this system directly, we can produce an INSERT that is competitive with using the raw database API directly.
Alternatively, the SQLAlchemy ORM offers the Bulk Operations suite of methods, which provide hooks into subsections of the unit of work process in order to emit Core-level INSERT and UPDATE constructs with a small degree of ORM-based automation.
The example below illustrates time-based tests for several different methods of inserting rows, going from the most automated to the least. With cPython 2.7, runtimes observed:
classics-MacBook-Pro:sqlalchemy classic$ python test.py SQLAlchemy ORM: Total time for 100000 records 12.0471920967 secs SQLAlchemy ORM pk given: Total time for 100000 records 7.06283402443 secs SQLAlchemy ORM bulk_save_objects(): Total time for 100000 records 0.856323003769 secs SQLAlchemy Core: Total time for 100000 records 0.485800027847 secs sqlite3: Total time for 100000 records 0.487842082977 sec

I prefer to convert arrays to strings:
Assert.assertEquals(
Arrays.toString(values),
Arrays.toString(new int[] { 7, 8, 9, 3 }));
this way I can see clearly where wrong values are. This works effectively only for small sized arrays, but I rarely use arrays with more items than 7 in my unit tests.
This method works for primitive types and for other types when overload of toString
returns all essential information.
There is much easier way:
props.load(new InputStreamReader(new FileInputStream("properties_file"), "UTF8"));
You can use the multiprocessing module. For this case I might use a processing pool:
from multiprocessing import Pool
pool = Pool()
result1 = pool.apply_async(solve1, [A]) # evaluate "solve1(A)" asynchronously
result2 = pool.apply_async(solve2, [B]) # evaluate "solve2(B)" asynchronously
answer1 = result1.get(timeout=10)
answer2 = result2.get(timeout=10)
This will spawn processes that can do generic work for you. Since we did not pass processes
, it will spawn one process for each CPU core on your machine. Each CPU core can execute one process simultaneously.
If you want to map a list to a single function you would do this:
args = [A, B]
results = pool.map(solve1, args)
Don't use threads because the GIL locks any operations on python objects.
select
sum(a) as atotal,
sum(b) as btotal,
sum(c) as ctotal
from
yourtable t
where
t.id in (1, 2, 3)
List<string> empnames = (from e in emplist select e.Enaame).ToList();
Or
string[] empnames = (from e in emplist select e.Enaame).ToArray();
Etc...
Try using:
SELECT * FROM <tablename> WITH ROWLOCK XLOCK HOLDLOCK
This should make the lock exclusive and hold it for the duration of the transaction.
Rather than giving background-size:100%;
We can give background-size:contain;
Check out this for different options avaliable: http://www.css3.info/preview/background-size/
Use:
if (isset($_POST['user'])) {
//do something
}
But you probably should be using some more proper validation. Try a simple regex or a rock-solid implementation from Zend Framework or Symfony.
http://framework.zend.com/manual/en/zend.validate.introduction.html
http://symfony.com/doc/current/book/validation.html
Or even the built-in filter extension:
http://php.net/manual/en/function.filter-var.php
Never trust user input, be smart. Don't trust anything. Always make sure what you receive is really what you expect. If it should be a number, make SURE it's a number.
Much improved code:
$user = filter_var($_POST['user'], FILTER_SANITIZE_STRING);
$isValid = filter_var($user, FILTER_VALIDATE_REGEXP, array('options' => array('regexp' => "/^[a-zA-Z0-9]+$/")));
if ($isValid) {
// do something
}
Sanitization and validation.

This is the problem
double a[] = null;
Since a
is null
, NullPointerException
will arise every time you use it until you initialize it. So this:
a[i] = var;
will fail.
A possible solution would be initialize it when declaring it:
double a[] = new double[PUT_A_LENGTH_HERE]; //seems like this constant should be 7
IMO more important than solving this exception, is the fact that you should learn to read the stacktrace and understand what it says, so you could detect the problems and solve it.
java.lang.NullPointerException
This exception means there's a variable with null
value being used. How to solve? Just make sure the variable is not null
before being used.
at twoten.TwoTenB.(TwoTenB.java:29)
This line has two parts:
<init>
method in class TwoTenB
declared in package twoten
. When you encounter an error message with SomeClassName.<init>
, means the error was thrown while creating a new instance of the class e.g. executing the constructor (in this case that seems to be the problem).a[i] = var;
.From this line, other lines will be similar to tell you where the error arose. So when reading this:
at javapractice.JavaPractice.main(JavaPractice.java:32)
It means that you were trying to instantiate a TwoTenB
object reference inside the main
method of your class JavaPractice
declared in javapractice
package.
Use this method and pass your array in parameter
Collections.shuffle(arrayList);
This method return void so it will not give you a new list but as we know that array is passed as a reference type in Java so it will shuffle your array and save shuffled values in it. That's why you don't need any return type.
You can now use arraylist which is shuffled.
I found a good example showing the differences between all hibernate save methods:
http://www.journaldev.com/3481/hibernate-session-merge-vs-update-save-saveorupdate-persist-example
In brief, according to the above link:
save()
persist()
saveOrUpdate()
Can be used with or without the transaction, and just like save(), if its used without the transaction, mapped entities wont be saved un;ess we flush the session.
Results into insert or update queries based on the provided data. If the data is present in the database, update query is executed.
update()
merge()
Also for practical examples of all these, please refer to the link I mentioned above, it shows examples for all these different methods.
If you have ArrayList then convert into Array[Object]
ArrayList<String> list = new ArrayList<String>();
PreparedStatement pstmt =
conn.prepareStatement("select * from employee where id in (?)");
Array array = conn.createArrayOf("VARCHAR", list.toArray());
pstmt.setArray(1, array);
ResultSet rs = pstmt.executeQuery();
Upcasting and Downcasting:
Upcasting: Casting from Derived-Class to Base Class Downcasting: Casting from Base Class to Derived Class
Let's understand the same as an example:
Consider two classes Shape as My parent class and Circle as a Derived class, defined as follows:
class Shape
{
public int Width { get; set; }
public int Height { get; set; }
}
class Circle : Shape
{
public int Radius { get; set; }
public bool FillColor { get; set; }
}
Upcasting:
Shape s = new Shape();
Circle c= s;
Both c and s are referencing to the same memory location, but both of them have different views i.e using "c" reference you can access all the properties of the base class and derived class as well but using "s" reference you can access properties of the only parent class.
A practical example of upcasting is Stream class which is baseclass of all types of stream reader of .net framework:
StreamReader reader = new StreamReader(new FileStreamReader());
here, FileStreamReader() is upcasted to streadm reder.
Downcasting:
Shape s = new Circle(); here as explained above, view of s is the only parent, in order to make it for both parent and a child we need to downcast it
var c = (Circle) s;
The practical example of Downcasting is button class of WPF.
Use option bty = "n"
in legend
to remove the box around the legend. For example:
legend(1, 5,
"This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",
bty = "n")
If you're using Brunch, the plugin Constangular helps you to manage variables for different environments.
Use which.min
:
df <- data.frame(Name=c('A','B','C','D'), Amount=c(150,120,175,160))
df[which.min(df$Amount),]
> df[which.min(df$Amount),]
Name Amount
2 B 120
From the help docs:
Determines the location, i.e., index of the (first) minimum or maximum of a numeric (or logical) vector.
What you are looking for is a "diff algorithm". A quick google search led me to this solution. I did not test it, but maybe it will do what you need.
pep8 was recently added to PyPi.
It is now super easy to check your code against pep8.
Adding my two bits. I needed a busy-wait for testing purposes. I didn't want to split the code as that would be a lot of work, so a simple for did it for me.
for (var i=0;i<1000000;i++){
//waiting
}
I don't see any downside in doing this and it did the trick for me.
Thank you so much! <%Response.Buffer = False%> worked like a charm! My asp/HTML table that was returning a blank page at about 2700 records. The following debugging lines helped expose the buffering problem: I replace the Do While loop as follows and played with my limit numbers to see what was happening:
Replace
Do While not rs.EOF
'etc .... your block of code that writes the table rows
rs.moveNext
Loop
with
Do While reccount < 2500
if rs.EOF then recount = 2501
'etc .... your block of code that writes the table rows
rs.moveNext
Loop
response.write "recount = " & recount
raise or lower the 2500 and 2501 to see if it is a buffer problem. for my record set, I could see that the blank page return, blank table, was happening at about 2700 records, good luck to all and thank you again for solving this problem! Such a simple great solution!
Other thing that solved my problem is to go under Target -> Build Settings -> Other linker Flags and delete the "-framework" and your framework "name".
It happened when i tried to remove a pod.
var orig = new Date();
var copy = new Date(+orig);
console.log(orig, copy);

Wouldn't this be a better solution?
var text = 'http://localhost/mysite/includes/phpThumb.php?src=http://media2.jupix.co.uk/v3/clients/4/properties/795/IMG_795_1_large.jpg&w=592&aoe=1&q=100';
var newSrc = 'www.google.com';
var newText = text.replace(/(src=).*?(&)/,'$1' + newSrc + '$2');
EDIT:
added some clarity in code and kept 'src' in the resulting link
$1
represents first part within the ()
(i.e) src=
and $2
represents the second part within the ()
(i.e) &
, so this indicates you are going to change the value between src
and &
. More clear, it should be like this:
src='changed value'& // this is to be replaced with your original url
ADD-ON for replacing all the ocurrences:
If you have several parameters with the same name, you can append to the regex global flag, like this text.replace(/(src=).*?(&)/g,'$1' + newSrc + '$2');
and that will replaces all the values for those params that shares the same name.
To make it simple, setup.py is run as "__main__"
when you call the install functions the other answers mentioned. Inside setup.py, you should put everything needed to install your package.
The following two sections discuss two things many setup.py modules have.
This function allows you to specify project attributes like the name of the project, the version.... Most importantly, this function allows you to install other functions if they're packaged properly. See this webpage for an example of setuptools.setup
These attributes of setuptools.setup enable installing these types of packages:
Packages that are imported to your project and listed in PyPI using setuptools.findpackages:
packages=find_packages(exclude=["docs","tests", ".gitignore", "README.rst","DESCRIPTION.rst"])
Packages not in PyPI, but can be downloaded from a URL using dependency_links
dependency_links=["http://peak.telecommunity.com/snapshots/",]
In an ideal world, setuptools.setup
would handle everything for you. Unfortunately this isn't always the case. Sometimes you have to do specific things, like installing dependencies with the subprocess command, to get the system you're installing on in the right state for your package. Try to avoid this, these functions get confusing and often differ between OS and even distribution.

i faced this same, i check in in program and feature. there was an update has install for jdk1.8 which is not compatible with my old setting(jdk1.6.0) for ant in eclipse. I install that update. right now, my ant project is build success.
Try it, hope this will be helpful.
Assuming a Windows installation, do please refer to this:
http://www.oracle-base.com/articles/misc/ManualOracleUninstall.php
- Uninstall all Oracle components using the Oracle Universal Installer (OUI).
- Run regedit.exe and delete the HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE key. This contains registry entires for all Oracle products.
- Delete any references to Oracle services left behind in the following part of the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Ora*
It should be pretty obvious which ones relate to Oracle.- Reboot your machine.
- Delete the "C:\Oracle" directory, or whatever directory is your ORACLE_BASE.
- Delete the "C:\Program Files\Oracle" directory.
- Empty the contents of your "C:\temp" directory.
- Empty your recycle bin.
Calling additional attention to some great comments that were left here:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ORACLE
key from the registry.%ORACLE_HOME%
.%PATH%
.This set of instructions happens to match an almost identical process that I had reverse-engineered myself over the years after a few messed-up Oracle installs, and has almost always met the need.
Note that even if the OUI is no longer available or doesn't work, simply following the remaining steps should still be sufficient.
(Revision #7 reverted as to not misquote the original source, and to not remove credit to the other comments that contributed to the answer. Further edits are appreciated (and then please remove this comment), if a way can be found to maintain these considerations.)
I've got the same error. I have been trying to fixing this by setting higher permission to account running SQL Client service, however it didnt help. The problem was that I run MS Sql Management studio just within my account. So, next time... assure that you are running it as Run as Administrator, if using Win7 with UAC enabled.
Yes, you can indeed. There are three ways of achieving this that I can think of.
Notes:
could you please try below code
<c:forEach var="hash" items="${map['key']}">
<option><c:out value="${hash}"/></option>
</c:forEach>
You may use the following method to remove last n

public String removeLast(String s, int n) {
if (null != s && !s.isEmpty()) {
s = s.substring(0, s.length()-n);

//cookieManager.removeSessionCookie();
// and/or
//cookieManager.removeAllCookie();"
Compare the set value with those that are set by the browser. Adjust the request for the installation of the cookies before until "flags" browser is not installed will fit with what You decide. I found that a query can be "flags":
// You may want to add the secure flag for https:
+ "; secure"
// In case you wish to convert session cookies to have an expiration:
+ "; expires=Thu, 01-Jan-2037 00:00:10 GMT"
// These flags I found in the database:
+ "; path=/registration"
+ "; domain=my.app.site.com"
also you can use "readonly"
<select id="xxx" name="xxx" class="input-medium" readonly>
Here is a simple answer using pandas
.
import pandas as pd
list1 = ['foo', 'fob', 'faz', 'funk']
string = 'bar'
list2 = (pd.Series(list1) + string).tolist()
list2
# ['foobar', 'fobbar', 'fazbar', 'funkbar']
Your stored procedure could easily be used as a view instead. Then you can join it on to anything else you need.
SQL:
CREATE VIEW vwTenantBalance
AS
SELECT tenant.ID AS TenantID, SUM(ISNULL(trans.Amount,0)) AS TenantBalance
FROM tblTenant tenant
LEFT JOIN tblTransaction trans
ON tenant.ID = trans.TenantID
GROUP BY tenant.ID
The you can do any statement like:
SELECT t.TenantName, t.CarPlateNumber, t.CarColor, t.Sex, t.SSNO, t.Phone,
t.Memo, u.UnitNumber, p.PropertyName, TenantBalance
FROM tblTenant t
LEFT JOIN tblRentalUnit u
ON t.UnitID = u.ID
LEFT JOIN tblProperty p
ON u.PropertyID = p.ID
LEFT JOIN vwTenantBalance v
ON t.ID = v.tenantID
ORDER BY p.PropertyName, t.CarPlateNumber

According to the DynamoDB documentation you could just delete the full table.
See below:
"Deleting an entire table is significantly more efficient than removing items one-by-one, which essentially doubles the write throughput as you do as many delete operations as put operations"
If you wish to delete only a subset of your data, then you could make separate tables for each month, year or similar. This way you could remove "last month" and keep the rest of your data intact.
This is how you delete a table in Java using the AWS SDK:
DeleteTableRequest deleteTableRequest = new DeleteTableRequest()
.withTableName(tableName);
DeleteTableResult result = client.deleteTable(deleteTableRequest);
The correct format for url can be one of the following formats:
jdbc:oracle:thin:@<hostName>:<portNumber>:<sid>; (if you have sid)
jdbc:oracle:thin:@//<hostName>:<portNumber>/serviceName; (if you have oracle service name)
And don't put any space there. Try to use 1521 as port number. sid (database name) must be the same as the one which is in environment variables (if you are using windows).
this type of error generally occurs when you have to put characters or values more than that you have specified in Database table like in this case:
you specify
transaction_status varchar(10)
but you actually trying to store
_transaction_status
which contain 19 characters.
that's why you faced this type of error in this code..
Try
webView.setBackgroundColor(0);
First convert the value in a string to iterate it, Them each value can be convert to a Integer value = 12345
l = [ int(item) for item in str(value) ]
In your template you can do like this:
{% jump_link as name %}
{% for obj in name %}
<div>{{obj.helo}} - {{obj.how}}</div>
{% endfor %}
In your template-tags you can add a tag like this:
@register.assignment_tag
def jump_link():
listArr = []
for i in range(5):
listArr.append({"helo" : i,"how" : i})
return listArr
To insert a single row of data:
INSERT INTO USERS
VALUES (1, 'Mike', 'Jones');
To do an insert on specific columns (as opposed to all of them) you must specify the columns you want to update.
INSERT INTO USERS (FIRST_NAME, LAST_NAME)
VALUES ('Stephen', 'Jiang');
To insert multiple rows of data in SQL Server 2008 or later:
INSERT INTO USERS VALUES
(2, 'Michael', 'Blythe'),
(3, 'Linda', 'Mitchell'),
(4, 'Jillian', 'Carson'),
(5, 'Garrett', 'Vargas');
To insert multiple rows of data in earlier versions of SQL Server, use "UNION ALL" like so:
INSERT INTO USERS (FIRST_NAME, LAST_NAME)
SELECT 'James', 'Bond' UNION ALL
SELECT 'Miss', 'Moneypenny' UNION ALL
SELECT 'Raoul', 'Silva'
Note, the "INTO" keyword is optional in INSERT queries. Source and more advanced querying can be found here.
I met the same problem even using -ldl
.
Besides this option, source files need to be placed before libraries, see undefined reference to `dlopen'.
If you want some space at left
and right
of input
view, you can add some padding like
private fun showAlertWithTextInputLayout(context: Context) {
val textInputLayout = TextInputLayout(context)
textInputLayout.setPadding(
resources.getDimensionPixelOffset(R.dimen.dp_19), // if you look at android alert_dialog.xml, you will see the message textview have margin 14dp and padding 5dp. This is the reason why I use 19 here
0,
resources.getDimensionPixelOffset(R.dimen.dp_19),
0
)
val input = EditText(context)
textInputLayout.hint = "Email"
textInputLayout.addView(input)
val alert = AlertDialog.Builder(context)
.setTitle("Reset Password")
.setView(textInputLayout)
.setMessage("Please enter your email address")
.setPositiveButton("Submit") { dialog, _ ->
// do some thing with input.text
dialog.cancel()
}
.setNegativeButton("Cancel") { dialog, _ ->
dialog.cancel()
}.create()
alert.show()
}
dimens.xml
<dimen name="dp_19">19dp</dimen>
Hope it help

I have approximately these problem. I need debug AngularJs application from Visual Studio 2013.
By default IIS Express restricted access to local files (like json).
But, first: JSON have JavaScript syntax.
Second: javascript files is allowed.
So:
rename JSON to JS (data.json->data.js
).
correct load command ($http.get('App/data.js').success(function (data) {...
load script data.js to page (<script src="App/data.js"></script>
)
Next use loaded data an usual manner. It is just workaround, of course.
You can simply add a FontAwesome icon to your select dropdown as text. You only need a few things in CSS only, the FontAwesome CSS and the unicode. For example 
:
select {_x000D_
font-family: 'FontAwesome', 'Second Font name'_x000D_
}
_x000D_
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.1/css/font-awesome.min.css" rel="stylesheet"/>_x000D_
<select>_x000D_
<option>Hi, </option>_x000D_
<option>Hi, </option>_x000D_
<option>Hi, </option>_x000D_
<option>Hi, </option>_x000D_
<option>Hi, </option>_x000D_
</select>
_x000D_
The unicodes can be found when you click on an icon: Fontawesome
According to the comment below and issue on Github, the unicode in select elements won't work on OSX (yet).
Update: from the Github issue, adding multiple
attribute to select
element makes it work on:
OSX El Capitan 10.11.4

If you have @oneToOne
mapping set to FetchType.LAZY
and you use second query (because you need Department objects to be loaded as part of Employee objects) what Hibernate will do is, it will issue queries to fetch Department objects for every individual Employee object it fetches from DB.
Later, in the code you might access Department objects via Employee to Department single-valued association and Hibernate will not issue any query to fetch Department object for the given Employee.
Remember, Hibernate still issues queries equal to the number of Employees it has fetched. Hibernate will issue same number of queries in both above queries, if you wish to access Department objects of all Employee objects

It was not asked precisely to remove accent (only special characters), but I needed to.
The solutions givens here works but they don’t remove accent: é, è, etc.

In the case of stored procedure update, you should delete it from the .dbml file and reinsert it again. But if the stored procedure have two paths (ex: if something; display some columns; else display some other columns), make sure the two paths have the same columns aliases!!! Otherwise only the first path columns will exist.
It means
myclass *p = NULL;
*p = ...; // illegal: dereferencing NULL pointer
... = *p; // illegal: dereferencing NULL pointer
p->meth(); // illegal: equivalent to (*p).meth(), which is dereferencing NULL pointer
myclass *p = /* some legal, non-NULL pointer */;
*p = ...; // Ok
... = *p; // Ok
p->meth(); // Ok, if myclass::meth() exists
basically, almost anything involving (*p)
or implicitly involving (*p)
, e.g. p->...
which is a shorthand for (*p). ...
; except for pointer declaration.
Use .parentElement
and you can't go wrong as long as you aren't using document fragments.
If you use document fragments, then you need .parentNode
:
let div = document.createDocumentFragment().appendChild(document.createElement('div'));
div.parentElement // null
div.parentNode // document fragment
Also:
let div = document.getElementById('t').content.firstChild_x000D_
div.parentElement // null_x000D_
div.parentNode // document fragment
_x000D_
<template id="t"><div></div></template>
_x000D_
Apparently the <html>
's .parentNode
links to the Document. This should be considered a decision phail as documents aren't nodes since nodes are defined to be containable by documents and documents can't be contained by documents.
I had this issue with Jenkins. The cause: I had renamed a module module
to Module
. I found out that git had gotten confused somehow and kept both module
and Module
directories, with the contents spread between both folders. The build.gradle
was kept in module
but the module's name was Module
so it was unable to find the default configuration.
I fixed it by backing up the contents of Module
, manually deleting module
folder from the repo and restoring + pushing the lost files.
In your case the "Vendor code 17002" is the equivalent of the ORA-12541 error: It's most likely that your listener is down, or has an improper port or service name. From the docs:
ORA-12541: TNS no listener
Cause: Listener for the source repository has not been started.
Action: Start the Listener on the machine where the source repository resides.
There is no way to do this in Chrome as yet (Chrome 58)
I have found the best solution is to open the url in an Incognito window, which will force you to re-enter the basic authentication credentials.
When you want to change the credentials, close the Incognito window and launch another Incognito window.
Check for secure_path on sudo
[root@host ~]# sudo -V | grep 'Value to override'
Value to override user's $PATH with: /sbin:/bin:/usr/sbin:/usr/bin
If $PATH

and edit /etc/sudoers
Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin
You can try onload event as well;
var createIframe = function (src) {
var self = this;
$('<iframe>', {
src: src,
id: 'iframeId',
frameborder: 1,
scrolling: 'no',
onload: function () {
self.isIframeLoaded = true;
console.log('loaded!');
}
}).appendTo('#iframeContainer');
};
If the other tips here don't work and - just like me - you're using the pandas
integration through progress_apply
, you can let tqdm
handle it:
from tqdm.autonotebook import tqdm
tqdm.pandas()
df.progress_apply(row_function, axis=1)
The main point here lies in the tqdm.autonotebook
module. As stated in their instructions for use in IPython Notebooks, this makes tqdm
choose between progress bar formats used in Jupyter notebooks and Jupyter consoles - for a reason still lacking further investigations on my side, the specific format chosen by tqdm.autonotebook
works smoothly in pandas
, while all others didn't, for progress_apply
specifically.

provided : This is much like compile, but indicates you expect the JDK or a container to provide the dependency at runtime. For example, when building a web application for the Java Enterprise Edition, you would set the dependency on the Servlet API and related Java EE APIs to scope provided because the web container provides those classes. This scope is only available on the compilation and test classpath, and is not transitive.

The System.Math.Round
method uses the Double
structure, which, as others have pointed out, is prone to floating point precision errors. The simple solution I found to this problem when I encountered it was to use the System.Decimal.Round
method, which doesn't suffer from the same problem and doesn't require redifining your variables as decimals:
Decimal.Round(0.575, 2, MidpointRounding.AwayFromZero)
Result: 0.58
One solution would be to use the plt.legend
function, even if you don't want an actual legend. You can specify the placement of the legend box by using the loc
keyterm. More information can be found at this website but I've also included an example showing how to place a legend:
ax.scatter(xa,ya, marker='o', s=20, c="lightgreen", alpha=0.9)
ax.scatter(xb,yb, marker='o', s=20, c="dodgerblue", alpha=0.9)
ax.scatter(xc,yc marker='o', s=20, c="firebrick", alpha=1.0)
ax.scatter(xd,xd,xd, marker='o', s=20, c="goldenrod", alpha=0.9)
line1 = Line2D(range(10), range(10), marker='o', color="goldenrod")
line2 = Line2D(range(10), range(10), marker='o',color="firebrick")
line3 = Line2D(range(10), range(10), marker='o',color="lightgreen")
line4 = Line2D(range(10), range(10), marker='o',color="dodgerblue")
plt.legend((line1,line2,line3, line4),('line1','line2', 'line3', 'line4'),numpoints=1, loc=2)
Note that because loc=2
, the legend is in the upper-left corner of the plot. And if the text overlaps with the plot, you can make it smaller by using legend.fontsize
, which will then make the legend smaller.
That's simple, if you reference them by index. If you want to hide the first column, you would:
Copy code
$('#thetable tr').find('td:nth-child(1),th:nth-child(1)').toggle();
The reason I first selected all table rows and then both td's and th's that were the n'th child is so that we wouldn't have to select the table and all table rows twice. This improves script execution speed. Keep in mind, nth-child()
is 1
based, not 0
.
It flushes the internal buffer, which is supposed to cause the OS to write out the buffer to the file.[1] Python uses the OS's default buffering unless you configure it do otherwise.
But sometimes the OS still chooses not to cooperate. Especially with wonderful things like write-delays in Windows/NTFS. Basically the internal buffer is flushed, but the OS buffer is still holding on to it. So you have to tell the OS to write it to disk with os.fsync()
in those cases.
UPDATE: This no longer works in the current version, see below for correct answer (no need to vote down, this is correct on older versions).
Use the JsonTextReader
class with a StreamReader
or use the JsonSerializer
overload that takes a StreamReader
directly:
var serializer = new JsonSerializer();
serializer.Deserialize(streamReader);
the function Position
in funprog {base} also does the job. It allows you to pass an arbitrary function, and returns the first or last match.
Position(f, x, right = FALSE, nomatch = NA_integer)
I think, after the inclusion of 'track by', you can use it in ng-options to get what you wanted, like the following
<select ng-model="somethingHere" ng-options="option.name for option in options track by option.value" ></select>
This way of doing it is better because when you want to replace the list of strings with list of objects you will just change this to
<select ng-model="somethingHere" ng-options="object.name for option in options track by object.id" ></select>
where somethingHere is an object with the properties name and id, of course. Please note, 'as' is not used in this way of expressing the ng-options, because it will only set the value and you will not be able to change it when you are using track by
If you wish to use the bound column value, you can simply refer to the combo:

You can also refer to the column property:

while doing performance testing, the measure i go by is RPS, that is how many requests per second can the server serve within acceptable latency.
theoretically one server can only run as many requests concurrently as number of cores on it..
It doesn't look like the problem is ASP.net's threading model, since it can potentially serve thousands of rps. It seems like the problem might be your application. Are you using any synchronization primitives ?
also whats the latency on your web services, are they very quick to respond (within microseconds), if not then you might want to consider asynchronous calls, so you dont end up blocking
If this doesnt yeild something, then you might want to profile your code using visual studio or redgate profiler
Where you say you're changing the value of the first element;
x = Integer.valueOf(9);
You're changing x
to point to an entirely new Integer, but never using it again. You're not changing the collection in any way.
Since you're working with ArrayList, you can use ListIterator if you want an iterator that allows you to change the elements, this is the snippet of your code that would need to be changed;
//initialize the Iterator
ListIterator<Integer> i = a.listIterator();//changed the value of frist element in List
if(i.hasNext()) {
i.next();
i.set(Integer.valueOf(9)); // Change the element the iterator is currently at
}// New iterator, and print all the elements
Iterator iter = a.iterator();
while(iter.hasNext())
System.out.print(iter.next());>> 912345678
Sadly the same cannot be extended to other collections like Set<T>. Implementation details (a HashSet for example being implemented as a hash table and changing the object could change the hash value and therefore the iteration order) makes Set<T> a "add new/remove only" type of data structure, and changing the content at all while iterating over it is not safe.
I was looking for an easy solution to deal with the unix symbolic links on windows. Thank you very much for the above Git aliases. There is one little optimization that can be done to the rm-symlinks so that it doesn't delete the files in the destination folder in case the alias is run a second time accidentally. Please observe the new if condition in the loop to make sure the file is not already a link to a directory before the logic is run.
git config --global alias.rm-symlinks '!__git_rm_symlinks(){
for symlink in $(git ls-files -s | egrep "^120000" | cut -f2); do
*if [ -d "$symlink" ]; then
continue

git rm-symlink "$symlink"
git update-index --assume-unchanged "$symlink"

The Java way to do what you want is to use the ServiceLoader mechanism.
Also many people roll their own by having a file in a well known classpath location (i.e. /META-INF/services/myplugin.properties) and then using ClassLoader.getResources() to enumerate all files with this name from all jars. This allows each jar to export its own providers and you can instantiate them by reflection using Class.forName()

A simple way using std::next_permutation
:
#include <iostream>
#include <algorithm>
#include <vector>
int main() {
int n, r;
std::cin >> n;
std::cin >> r;
std::vector<bool> v(n);
std::fill(v.end() - r, v.end(), true);
do {
for (int i = 0; i < n; ++i) {
if (v[i]) {
std::cout << (i + 1) << " ";
}
}
std::cout << "\n";
} while (std::next_permutation(v.begin(), v.end()));
return 0;
}
or a slight variation that outputs the results in an easier to follow order:
#include <iostream>
#include <algorithm>
#include <vector>
int main() {
int n, r;
std::cin >> n;
std::cin >> r;
std::vector<bool> v(n);
std::fill(v.begin(), v.begin() + r, true);
do {
for (int i = 0; i < n; ++i) {
if (v[i]) {
std::cout << (i + 1) << " ";
}
}
std::cout << "\n";
} while (std::prev_permutation(v.begin(), v.end()));
return 0;
}
A bit of explanation:
It works by creating a "selection array" (v
), where we place r
selectors, then we create all permutations of these selectors, and print the corresponding set member if it is selected in in the current permutation of v
.
You can implement it if you note that for each level r you select a number from 1 to n.
In C++, we need to 'manually' keep the state between calls that produces results (a combination): so, we build a class that on construction initialize the state, and has a member that on each call returns the combination while there are solutions: for instance
#include <iostream>
#include <iterator>
#include <vector>
#include <cstdlib>
using namespace std;
struct combinations
{
typedef vector<int> combination_t;
// initialize status
combinations(int N, int R) :
completed(N < 1 || R > N),
generated(0),
N(N), R(R)
{
for (int c = 1; c <= R; ++c)
curr.push_back(c);
}
// true while there are more solutions
bool completed;
// count how many generated
int generated;
// get current and compute next combination
combination_t next()
{
combination_t ret = curr;
// find what to increment
completed = true;
for (int i = R - 1; i >= 0; --i)
if (curr[i] < N - R + i + 1)
{
int j = curr[i] + 1;
while (i <= R-1)
curr[i++] = j++;
completed = false;
++generated;
break;
}
return ret;
}
private:
int N, R;
combination_t curr;
};
int main(int argc, char **argv)
{
int N = argc >= 2 ? atoi(argv[1]) : 5;
int R = argc >= 3 ? atoi(argv[2]) : 2;
combinations cs(N, R);
while (!cs.completed)
{
combinations::combination_t c = cs.next();
copy(c.begin(), c.end(), ostream_iterator<int>(cout, ","));
cout << endl;
}
return cs.generated;
}

Not a method for sending email, but you can use an online Git server (e.g. Bitbucket or a similar service) for that.
This way, you can use git push
commands, and all versions will be stored in a compressed and organized way.
