I went through the answers here and elsewhere and still had issues. It turned that (like the op), I was running in kubernetes, and the app was fine, but kubernetes had an issue.
I forgot to have my app start based on my port environment variable. So, kubernetes/helm was telling it to run on 8443 and to liveness probe that, but it was running on some other port (like 8123) from my application.properties.
The kubernetes events (get events) showed the live-ness probe was failing, so kubernetes was killing the pod/app every 30 seconds or so.

I got below error :
Found the synthetic property @collapse. Please include either "BrowserAnimationsModule" or "NoopAnimationsModule" in your application.
I follow the accepted answer by Ploppy and it resolved my problem.
Here are the steps:
1.
import { trigger, state, style, transition, animate } from '@angular/animations';
Or
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
2. Define the same in the import array in the root module.
It will resolve the error. Happy coding!!

ECMA-48 - Control Functions for Coded Character Sets, 5th edition (June 1991) - A standard defining the color control codes, that is apparently supported also by xterm.
SGR 38 and 48 were originally reserved by ECMA-48, but were fleshed out a few years later in a joint ITU, IEC, and ISO standard, which comes in several parts and which (amongst a whole lot of other things) documents the SGR 38/48 control sequences for direct colour and indexed colour:

If you need to interact directly with the DOM element, why not just use document.getElementById
since, if you are trying to interact with a specific element you will probably know the id, as assuming that the classname is on only one element or some other option tends to be risky.
But, I tend to agree with the others, that in most cases you should learn to do what you need using what jQuery gives you, as it is very flexible.
UPDATE: Based on a comment: Here is a post with a nice explanation: http://www.mail-archive.com/[email protected]/msg04461.html
$(this).attr("checked") ? $(this).val() : 0
This will return the value if it's checked, or 0 if it's not.
$(this).val()
is just reaching into the dom and getting the attribute "value" of the element, whether or not it's checked.
It's really not an 'either/or' situation. AJAX stands for Asynchronous JavaScript and XML, and JQuery is a JavaScript library that takes the pain out of writing common JavaScript routines.
It's the difference between a thing (jQuery) and a process (AJAX). To compare them would be to compare apples and oranges.
Just in case someone else needs an F# version of the above described hack.

To avoid problems of side effects after changing env
, especially using multiple nodes, it is better to set a temporary context.
One safe way to alter the environment is:
withEnv(['MYTOOL_HOME=/usr/local/mytool']) {
sh '$MYTOOL_HOME/bin/start'
}
This approach does not poison the env after the command execution.
I would have to say that one of my favorites is putting the help window in a new tab:
:tab help <help_topic>
This opens up help in a new tab and, as somebody that loves Vim tabs, this is ridiculously useful.
No, there is no "easy" way. Your best bet would be to do a loop where you first check each previous sibling, then move to the parent node and all of its previous siblings.
You'll need to break the selector into two, 1 to check if the current node could be the top level node in your selector, and 1 to check if it's descendants match.
Edit: This might as well be a plugin. You can use this with any selector in any HTML:
(function($) {
$.fn.closestPrior = function(selector) {
selector = selector.replace(/^\s+|\s+$/g, "");
var combinator = selector.search(/[ +~>]|$/);
var parent = selector.substr(0, combinator);
var children = selector.substr(combinator);
var el = this;
var match = $();
while (el.length && !match.length) {
el = el.prev();
if (!el.length) {
var par = el.parent();
// Don't use the parent - you've already checked all of the previous
// elements in this parent, move to its previous sibling, if any.
while (par.length && !par.prev().length) {
par = par.parent();
}
el = par.prev();
if (!el.length) {
break;
}
}
if (el.is(parent) && el.find(children).length) {
match = el.find(children).last();
}
else if (el.find(selector).length) {
match = el.find(selector).last();
}
}
return match;
}
})(jQuery);

Generally, you don't need all those levels, SEVERE, WARNING, INFO, FINE might be enough. We're using Log4J (not java.util.logging directly) and the following levels (which might differ in name from other logging frameworks):
ERROR: Any error/exception that is or might be critical. Our Logger automatically sends an email for each such message on our servers (usage: logger.error("message");
)
WARN: Any message that might warn us of potential problems, e.g. when a user tried to log in with wrong credentials - which might indicate an attack if that happens often or in short periods of time (usage: logger.warn("message");
)
INFO: Anything that we want to know when looking at the log files, e.g. when a scheduled job started/ended (usage: logger.info("message");
)
DEBUG: As the name says, debug messages that we only rarely turn on. (usage: logger.debug("message");
)
The beauty of this is that if you set the log level to WARN, info and debug messages have next to no performance impact. If you need to get additional information from a production system you just can lower the level to INFO or DEBUG for a short period of time (since you'd get much more log entries which make your log files bigger and harder to read). Adjusting log levels etc. can normally be done at runtime (our JBoss instance checks for changes in that config every minute or so).
Since you're doing substring searches (std::string) and not element (character) searches, there's unfortunately no existing solution I'm aware of that's immediately accessible in the standard library to do this.
Nevertheless, it's easy enough to do: simply convert both strings to upper case (or both to lower case - I chose upper in this example).
std::string upper_string(const std::string& str)
{
string upper;
transform(str.begin(), str.end(), std::back_inserter(upper), toupper);
return upper;
}
std::string::size_type find_str_ci(const std::string& str, const std::string& substr)
{
return upper(str).find(upper(substr) );
}
This is not a fast solution (bordering into pessimization territory) but it's the only one I know of off-hand. It's also not that hard to implement your own case-insensitive substring finder if you are worried about efficiency.
Additionally, I need to support std::wstring/wchar_t. Any ideas?
tolower/toupper in locale will work on wide-strings as well, so the solution above should be just as applicable (simple change std::string to std::wstring).
[Edit] An alternative, as pointed out, is to adapt your own case-insensitive string type from basic_string by specifying your own character traits. This works if you can accept all string searches, comparisons, etc. to be case-insensitive for a given string type.
For C# the solution is to cast the values to a double (as Math.Ceiling takes a double):
int nPages = (int)Math.Ceiling((double)nItems / (double)nItemsPerPage);
In java you should do the same with Math.ceil().
You could also use CEILING
which rounds up to an integer or desired multiple of significance
ie
=CEILING(A1,10)
rounds up to a multiple of 10

For upgrade code retrieval: How can I find the Upgrade Code for an installed MSI file?
The information below has grown considerably over time and may have become a little too elaborate. How to get product codes quickly? (four approaches):
Use the Powershell "one-liner"
Scroll down for screenshot and step-by-step. Disclaimer also below - minor or moderate risks depending on who you ask. Works OK for me. Any self-repair triggered by this option should generally be possible to cancel. The package integrity checks triggered does add some event log "noise" though. Note! IdentifyingNumber
is the ProductCode
(WMI peculiarity).
get-wmiobject Win32_Product | Sort-Object -Property Name |Format-Table IdentifyingNumber, Name, LocalPackage -AutoSize
Quick start of Powershell: hold Windows key, tap R, type in "powershell" and press Enter
Use VBScript
(script on github.com)Described below under "Alternative Tools" (section 3). This option may be safer than Powershell for reasons explained in detail below. In essence it is (much) faster and not capable of triggering MSI self-repair since it does not go through WMI (it accesses the MSI COM API directly - at blistering speed). However, it is more involved than the Powershell option (several lines of code).
Registry Lookup
Some swear by looking things up in the registry. Not my recommended approach - I like going through proper APIs (or in other words: OS function calls). There are always weird exceptions accounted for only by the internals of the API-implementation:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall
HKCU\Software\Microsoft\Windows\CurrentVersion\Uninstall
Original MSI File / WiX Source
You can find the Product Code
in the Property table
of any MSI file (and any other property as well). However, the GUID could conceivably (rarely) be overridden by a transform applied at install time and hence not match the GUID the product is registered under (approach 1 and 2 above will report the real product code - that is registered with Windows - in such rare scenarios).
You need a tool to view MSI files. See towards the bottom of the following answer for a list of free tools you can download (or see quick option below): How can I compare the content of two (or more) MSI files?
UPDATE: For convenience and need for speed :-), download SuperOrca without delay and fuss from this direct-download hotlink - the tool is good enough to get the job done - install, open MSI and go straight to the Property table and find the ProductCode
row (please always virus check a direct-download hotlink - obviously - you can use virustotal.com to do so - online scan utilizing dozens of anti-virus and malware suites to scan what you upload).
Orca is Microsoft's own tool, it is installed with Visual Studio and the Windows SDK. Try searching for
Orca-x86_en-us.msi
- underProgram Files (x86)
and install the MSI if found.
- Current path:
C:\Program Files (x86)\Windows Kits\10\bin\10.0.17763.0\x86
- Change version numbers as appropriate
And below you will find the original answer which "organically grew" into a lot of detail.
Maybe see "Uninstall MSI Packages" section below if this is the task you need to perform.
UPDATE: If you also need the upgrade code, check this answer: How can I find the Upgrade Code for an installed MSI file? (retrieves associated product codes, upgrade codes & product names in a table output - similar to the one below).
- Can't use PowerShell? See "Alternative Tools" section below.
- Looking to uninstall? See "Uninstall MSI packages" section below.
Fire up Powershell (hold down the Windows key, tap R, release the Windows key, type in "powershell" and press OK) and run the command below to get a list of installed MSI package product codes along with the local cache package path and the product name (maximize the PowerShell window to avoid truncated names).
Before running this command line, please read the disclaimer below (nothing dangerous, just some potential nuisances). Section 3 under "Alternative Tools" shows an alternative non-WMI way to get the same information using VBScript. If you are trying to uninstall a package there is a section below with some sample msiexec.exe command lines:
get-wmiobject Win32_Product | Format-Table IdentifyingNumber, Name, LocalPackage -AutoSize
The output should be similar to this:
Note! For some strange reason the "ProductCode" is referred to as "IdentifyingNumber" in WMI. So in other words - in the picture above the IdentifyingNumber is the ProductCode.
If you need to run this query remotely against lots of remote computer, see "Retrieve Product Codes From A Remote Computer" section below.
DISCLAIMER (important, please read before running the command!): Due to strange Microsoft design, any WMI call to
Win32_Product
(like the PowerShell command below) will trigger a validation of the package estate. Besides being quite slow, this can in rare cases trigger an MSI self-repair. This can be a small package or something huge - like Visual Studio. In most cases this does not happen - but there is a risk. Don't run this command right before an important meeting - it is not ever dangerous (it is read-only), but it might lead to a long repair in very rare cases (I think you can cancel the self-repair as well - unless actively prevented by the package in question, but it will restart if you call Win32_Product again and this will persist until you let the self-repair finish - sometimes it might continue even if you do let it finish: How can I determine what causes repeated Windows Installer self-repair?).And just for the record: some people report their event logs filling up with MsiInstaller EventID 1035 entries (see code chief's answer) - apparently caused by WMI queries to the Win32_Product class (personally I have never seen this). This is not directly related to the Powershell command suggested above, it is in context of general use of the WIM class Win32_Product.
You can also get the output in list form (instead of table):
get-wmiobject -class Win32_Product
In this case the output is similar to this:
In theory you should just be able to specify a remote computer name as part of the command itself. Here is the same command as above set up to run on the machine "RemoteMachine" (-ComputerName RemoteMachine
section added):
get-wmiobject Win32_Product -ComputerName RemoteMachine | Format-Table IdentifyingNumber, Name, LocalPackage -AutoSize
This might work if you are running with domain admin rights on a proper domain. In a workgroup environment (small office / home network), you probably have to add user credentials directly to the WMI calls to make it work.
Additionally, remote connections in WMI are affected by (at least) the Windows Firewall, DCOM settings, and User Account Control (UAC) (plus any additional non-Microsoft factors - for instance real firewalls, third party software firewalls, security software of various kinds, etc...). Whether it will work or not depends on your exact setup.
UPDATE: An extensive section on remote WMI running can be found in this answer: How can I find the Upgrade Code for an installed MSI file?. It appears a firewall rule and suppression of the UAC prompt via a registry tweak can make things work in a workgroup network environment. Not recommended changes security-wise, but it worked for me.
PowerShell requires the .NET framework to be installed (currently in version 3.5.1 it seems? October, 2017). The actual PowerShell application itself can also be missing from the machine even if .NET is installed. Finally I believe PowerShell can be disabled or locked by various system policies and privileges.
If this is the case, you can try a few other ways to retrieve product codes. My preferred alternative is VBScript - it is fast and flexible (but can also be locked on certain machines, and scripting is always a little more involved than using tools).
wbemtest.exe
.wbemtest.exe
(Hold down the Windows key, tap R, release the Windows key, type in "wbemtest.exe" and press OK).SELECT IdentifyingNumber,Name,Version FROM Win32_Product
and click "Use" (or equivalent - the tool will be localized).WMIExplorer.exe
SELECT IdentifyingNumber,Name,Version FROM Win32_Product
and press Execute.msiinfo.csv
.' Retrieve all ProductCodes (with ProductName and ProductVersion)
Set fso = CreateObject("Scripting.FileSystemObject")
Set output = fso.CreateTextFile("msiinfo.csv", True, True)
Set installer = CreateObject("WindowsInstaller.Installer")
On Error Resume Next ' we ignore all errors
For Each product In installer.ProductsEx("", "", 7)
productcode = product.ProductCode
name = product.InstallProperty("ProductName")
version=product.InstallProperty("VersionString")
output.writeline (productcode & ", " & name & ", " & version)
Next
output.Close
I can't think of any further general purpose options to retrieve product codes at the moment, please add if you know of any. Just edit inline rather than adding too many comments please.
You can certainly access this information from within your application by calling the MSI automation interface (COM based) OR the C++ MSI installer functions (Win32 API). Or even use WMI queries from within your application like you do in the samples above using
PowerShell
,wbemtest.exe
orWMIExplorer.exe
.
If what you want to do is to uninstall the MSI package you found the product code for, you can do this as follows using an elevated command prompt (search for cmd.exe, right click and run as admin):
Option 1: Basic, interactive uninstall without logging (quick and easy):
msiexec.exe /x {00000000-0000-0000-0000-00000000000C}
Quick Parameter Explanation:
/X = run uninstall sequence
{00000000-0000-0000-0000-00000000000C} = product code for product to uninstall
You can also enable (verbose) logging and run in silent mode if you want to, leading us to option 2:
Option 2: Silent uninstall with verbose logging (better for batch files):
msiexec.exe /x {00000000-0000-0000-0000-00000000000C} /QN /L*V "C:\My.log" REBOOT=ReallySuppress
Quick Parameter Explanation:
/X = run uninstall sequence
{00000000-0000-0000-0000-00000000000C} = product code for product to uninstall
/QN = run completely silently
/L*V "C:\My.log"= verbose logging at specified path
REBOOT=ReallySuppress = avoid unexpected, sudden reboot
There is a comprehensive reference for MSI uninstall here (various different ways to uninstall MSI packages): Uninstalling an MSI file from the command line without using msiexec. There is a plethora of different ways to uninstall.
If you are writing a batch file, please have a look at section 3 in the above, linked answer for a few common and standard uninstall command line variants.
And a quick link to msiexec.exe (command line options) (overview of the command line for msiexec.exe from MSDN). And the Technet version as well.
UPDATE: please find a new answer on how to find the upgrade code for installed packages instead of manually looking up the code in MSI files. For installed packages this is much more reliable. If the package is not installed, you still need to look in the MSI file (or the source file used to compile the MSI) to find the upgrade code. Leaving in older section below:
If you want to get the UpgradeCode or other MSI properties, you can open the cached installation MSI for the product from the location specified by "LocalPackage" in the image show above (something like: C:\WINDOWS\Installer\50c080ae.msi
- it is a hex file name, unique on each system). Then you look in the "Property table" for UpgradeCode (it is possible for the UpgradeCode to be redefined in a transform - to be sure you get the right value you need to retrieve the code programatically from the system - I will provide a script for this shortly. However, the UpgradeCode found in the cached MSI is generally correct).
To open the cached MSI files, use Orca or another packaging tool. Here is a discussion of different tools (any of them will do): What installation product to use? InstallShield, WiX, Wise, Advanced Installer, etc. If you don't have such a tool installed, your fastest bet might be to try Super Orca (it is simple to use, but not extensively tested by me).
UPDATE: here is a new answer with information on various free products you can use to view MSI files: How can I compare the content of two (or more) MSI files?
If you have Visual Studio installed, try searching for Orca-x86_en-us.msi
- under Program Files (x86)
- and install it (this is Microsoft's own, official MSI viewer and editor). Then find Orca in the start menu. Go time in no time :-). Technically Orca is installed as part of Windows SDK (not Visual Studio), but Windows SDK is bundled with the Visual Studio install. If you don't have Visual Studio installed, perhaps you know someone who does? Just have them search for this MSI and send you (it is a tiny half mb file) - should take them seconds. UPDATE: you need several CAB files as well as the MSI - these are found in the same folder where the MSI is found. If not, you can always download the Windows SDK (it is free, but it is big - and everything you install will slow down your PC). I am not sure which part of the SDK installs the Orca MSI. If you do, please just edit and add details here.
Similar topics (for reference and easy access - I should clean this list up):
If .java
file contains top level (not nested) public
class, it have same name as that public class. So if you have class like public class A{...}
it needs to be placed in A.java
file. Because of that we can't have two public classes in one .java
file.
If having two public classes would be allowed then, and lets say aside from public A
class file would also contain public class B{}
it would require from A.java
file to be also named as B.java
but files can't have two (or more) names (at least in all systems on which Java can be run).
So assuming your code is placed in StaticDemoShow.java
file you have two options:
If you want to have other class in same file make them non-public (lack of visibility modifier will represent default/package-private visibility)
class StaticDemo { // It can no longer public
static int a = 3;
static int b = 4;
static {
System.out.println("Voila! Static block put into action");
}
static void show() {
System.out.println("a= " + a);
System.out.println("b= " + b);
}
}
public class StaticDemoShow { // Only one top level public class in same .java file
public static void main() {
StaticDemo.show();
}
}
Move all public classes to their own .java
files. So in your case you would need to split it into two files:
StaticDemo.java
public class StaticDemo { // Note: same name as name of file
static int a = 3;
static int b = 4;
static {
System.out.println("Voila! Static block put into action");
}
static void show() {
System.out.println("a= " + a);
System.out.println("b= " + b);
}
}
StaticDemoShow.java
public class StaticDemoShow {
public static void main() {
StaticDemo.show();
}
}

{

Hope this helps!
The correct way in .NET 4.0 is:
if (String.IsNullOrWhiteSpace(strSearch))
The String.IsNullOrWhiteSpace
method used above is equivalent to:
if (strSearch == null || strSearch == String.Empty || strSearch.Trim().Length == 0)
// String.Empty is the same as ""
Reference for IsNullOrWhiteSpace method
http://msdn.microsoft.com/en-us/library/system.string.isnullorwhitespace.aspx
Indicates whether a specified string is Nothing, empty, or consists only of white-space characters.
In earlier versions, you could do something like this:
if (String.IsNullOrEmpty(strSearch) || strSearch.Trim().Length == 0)
The String.IsNullOrEmpty
method used above is equivalent to:
if (strSearch == null || strSearch == String.Empty)
Which means you still need to check for your "IsWhiteSpace" case with the .Trim().Length == 0
as per the example.
Reference for IsNullOrEmpty method
http://msdn.microsoft.com/en-us/library/system.string.isnullorempty.aspx
Indicates whether the specified string is Nothing or an Empty string.
Explanation:
You need to ensure strSearch
(or any variable for that matter) is not null
before you dereference it using the dot character (.
) - i.e. before you do strSearch.SomeMethod()
or strSearch.SomeProperty
you need to check that strSearch != null
.
In your example you want to make sure your string has a value, which means you want to ensure the string:
String.Empty
/ ""
)In the cases above, you must put the "Is it null?" case first, so it doesn't go on to check the other cases (and error) when the string is null
.
Two alternatives

There is a new DecisionTreeClassifier
method, decision_path
, in the 0.18.0 release. The developers provide an extensive (well-documented) walkthrough.
The first section of code in the walkthrough that prints the tree structure seems to be OK. However, I modified the code in the second section to interrogate one sample. My changes denoted with # <--
Edit The changes marked by # <--
in the code below have since been updated in walkthrough link after the errors were pointed out in pull requests #8653 and #10951. It's much easier to follow along now.

leaf node 4 reached, no decision here
Change the sample_id

Just found another reason why an element goes blurry when being transformed. I was using transform: translate3d(-5.5px, -18px, 0);
to re-position an element once it had been loaded in, however that element became blurry.
I tried all the suggestions above but it turned out that it was due to me using a decimal value for one of the translate values. Whole numbers don't cause the blur, and the further away I went from the whole number the worse the blur became.
i.e. 5.5px
blurs the element the most, 5.1px
the least.
Just thought I'd chuck this here in case it helps anybody.

, like so (untested): datetime.datetime(*(time.strptime('2011-06-09', '%Y-%m-%d')[0:6]))
Starting with the 2.6 release, another way to do this is to compare the field to an empty array:
ME.find({pictures: {$gt: []}})
Testing it out in the shell:
> db.ME.insert([
{pictures: [1,2,3]},
{pictures: []},
{pictures: ['']},
{pictures: [0]},
{pictures: 1},
{foobar: 1}
])
> db.ME.find({pictures: {$gt: []}})
{ "_id": ObjectId("54d4d9ff96340090b6c1c4a7"), "pictures": [ 1, 2, 3 ] }
{ "_id": ObjectId("54d4d9ff96340090b6c1c4a9"), "pictures": [ "" ] }
{ "_id": ObjectId("54d4d9ff96340090b6c1c4aa"), "pictures": [ 0 ] }
So it properly includes the docs where pictures
has at least one array element, and excludes the docs where pictures
is either an empty array, not an array, or missing.
to stop IIS manually:
you get a search result for the manager (Internet Information Services (IIS) manager, on the right side of it there are restart/stop/start buttons.
If you don't want IIS to start on startup because its really annoying..:
oh and IIS and xampp basically do the same thing just in a bit different way. ANd if you have Xampp for your projects then its not really all that nessecary to leave it on if you don't ever use it anyways.

The commandline interpreter does indeed have a FOR construct that you can use from the command prompt or from within a batch file.
For your purpose, you probably want something like:
FOR %i IN (*.ext) DO my-function %i
Which will result in the name of each file with extension *.ext in the current directory being passed to my-function (which could, for example, be another .bat file).
The (*.ext)
part is the "filespec", and is pretty flexible with how you specify sets of files. For example, you could do:
FOR %i IN (C:\Some\Other\Dir\*.ext) DO my-function %i
To perform an operation in a different directory.
There are scores of options for the filespec and FOR in general. See
HELP FOR
from the command prompt for more information.
For SQL Server 2005 upwards:
SELECT [name] AS [TableName], [create_date] AS [CreatedDate] FROM sys.tables
For SQL Server 2000 upwards:
SELECT so.[name] AS [TableName], so.[crdate] AS [CreatedDate]
FROM INFORMATION_SCHEMA.TABLES AS it, sysobjects AS so
WHERE it.[TABLE_NAME] = so.[name]
I fixed it like this example.
$scope.myCalendar = new Date(myUnixDate*1000);
<input date-time ng-model="myCalendar" format="DD/MM/YYYY" />
require(ggplot2)
require(nlme)
set.seed(101)
mp <-data.frame(year=1990:2010)
N <- nrow(mp)
mp <- within(mp,
{
wav <- rnorm(N)*cos(2*pi*year)+rnorm(N)*sin(2*pi*year)+5
wow <- rnorm(N)*wav+rnorm(N)*wav^3
})
m01 <- gls(wow~poly(wav,3), data=mp, correlation = corARMA(p=1))
Get fitted values (the same as m01$fitted
)
fit <- predict(m01)
Normally we could use something like predict(...,se.fit=TRUE)
to get the confidence intervals on the prediction, but gls
doesn't provide this capability. We use a recipe similar to the one shown at http://glmm.wikidot.com/faq :
V <- vcov(m01)
X <- model.matrix(~poly(wav,3),data=mp)
se.fit <- sqrt(diag(X %*% V %*% t(X)))
Put together a "prediction frame":
predframe <- with(mp,data.frame(year,wav,
wow=fit,lwr=fit-1.96*se.fit,upr=fit+1.96*se.fit))
Now plot with geom_ribbon
(p1 <- ggplot(mp, aes(year, wow))+
geom_point()+
geom_line(data=predframe)+
geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))
It's easier to see that we got the right answer if we plot against wav
rather than year
:
(p2 <- ggplot(mp, aes(wav, wow))+
geom_point()+
geom_line(data=predframe)+
geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))
It would be nice to do the predictions with more resolution, but it's a little tricky to do this with the results of poly()
fits -- see ?makepredictcall
.
I had a similar problem (differences being I wanted to return an object that was already converted to a json string and my controller get returns a IHttpActionResult)
Here is how I solved it. First I declared a utility class
public class RawJsonActionResult : IHttpActionResult
{
private readonly string _jsonString;
public RawJsonActionResult(string jsonString)
{
_jsonString = jsonString;
}
public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
{
var content = new StringContent(_jsonString);
content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
var response = new HttpResponseMessage(HttpStatusCode.OK) { Content = content };
return Task.FromResult(response);
}
}
This class can then be used in your controller. Here is a simple example
public IHttpActionResult Get()
{
var jsonString = "{\"id\":1,\"name\":\"a small object\" }";
return new RawJsonActionResult(jsonString);
}
This can be solved much easier than the other suggestions.
Simply draw a square and apply a border
property to just 2 joining sides.
Then rotate the square according to the direction you want the arrow to point, for exaple: transform: rotate(<your degree here>)
.triangle {_x000D_
border-right: 10px solid; _x000D_
border-bottom: 10px solid;_x000D_
height: 30px;_x000D_
width: 30px;_x000D_
transform: rotate(-45deg);_x000D_
}
_x000D_
<div class="triangle"></div>

I see a couple of issues.
First:
ser.read() is only going to return 1 byte at a time.
If you specify a count
ser.read(5)
it will read 5 bytes (less if timeout occurrs before 5 bytes arrive.)
If you know that your input is always properly terminated with EOL characters, better way is to use
ser.readline()
That will continue to read characters until an EOL is received.
Second:
Even if you get ser.read() or ser.readline() to return multiple bytes, since you are iterating over the return value, you will still be handling it one byte at a time.
Get rid of the
for line in ser.read():
and just say:
line = ser.readline()
Use following code : jsfiddle.net/KqHEC/

These answers are a bit dated. Therefore I give you:
hash = JSON.parse string
Rails should automagically load the json
module for you, so you don't need to add require 'json'
.
This works for uppercase and lowercase. I don't know how elegant you deem it to be.
def rot13(s):
rot=lambda x:chr(ord(x)+13) if chr(ord(x.lower())+13).isalpha()==True else chr(ord(x)-13)
s=[rot(i) for i in filter(lambda x:x!=',',map(str,s))]
return ''.join(s)
I found a simpler solution. If you have all the RPMs in the same directory, all you need to do is,
$ sudo rpm -i *.rpm
rpm
seems to figure out the correct order to install these and installs the RPMs.
I needed to spin freeipa container to have a working kdc and had to give it a hostname otherwise it wouldn't run.
What eventually did work for me is setting the HOSTNAME
env variable in compose:
version: 2
services:
freeipa:
environment:
- HOSTNAME=ipa.example.test
Now its working:
docker exec -it freeipa_freeipa_1 hostname
ipa.example.test
Here's my interpretation as a Function Instead:
'#######################################################################
'# LoopThroughFiles
'# Function to Loop through files in current directory and return filenames
'# Usage: LoopThroughFiles ActiveWorkbook.Path, "txt" 'inputDirectoryToScanForFile
'# https://stackoverflow.com/questions/10380312/loop-through-files-in-a-folder-using-vba
'#######################################################################
Function LoopThroughFiles(inputDirectoryToScanForFile, filenameCriteria) As String
Dim StrFile As String
'Debug.Print "in LoopThroughFiles. inputDirectoryToScanForFile: ", inputDirectoryToScanForFile
StrFile = Dir(inputDirectoryToScanForFile & "\*" & filenameCriteria)
Do While Len(StrFile) > 0
Debug.Print StrFile
StrFile = Dir
Loop
End Function
Another way of doing that is:
String date = dateAndTime.substring(0, dateAndTime.indexOf(" "));
I'm not exactly certain, but I think this might be faster/use less memory than using the .split()
method.
One more solution when you want to use data from any sell ( in the key C3
)
=SUMIF(Sheet6!M:M;CONCATENATE("<";TEXT(C3;"dd.mm.yyyy"));Sheet6!L:L)
One can issue the SQL*Plus command SET TIMING ON
to get wall-clock times, but one can't take, for example, fetch time out of that trivially.
The AUTOTRACE setting, when used as SET AUTOTRACE TRACEONLY
will suppress output, but still perform all of the work to satisfy the query and send the results back to SQL*Plus, which will suppress it.
Lastly, one can trace the SQL*Plus session, and manually calculate the time spent waiting on events which are client waits, such as "SQL*Net message to client", "SQL*Net message from client".
I can guarantee you that bash
alone won't be any faster than sed
for this task. Starting up external processes in bash
is a generally bad idea but only if you do it a lot.
So, if you're starting a sed
process for each line of your input, I'd be concerned. But you're not. You only need to start one sed
which will do all the work for you.
You may however find that the following sed
will be a bit faster than your version:
(whatever) | sed 's/...$//'
All this does is remove the last three characters on each line, rather than substituting the whole line with a shorter version of itself. Now maybe more modern RE engines can optimise your command but why take the risk.
To be honest, about the only way I can think of that would be faster would be to hand-craft your own C-based filter program. And the only reason that may be faster than sed
is because you can take advantage of the extra knowledge you have on your processing needs (sed
has to allow for generalised procession so may be slower because of that).
Don't forget the optimisation mantra: "Measure, don't guess!"
If you really want to do this one line at a time in bash
(and I still maintain that it's a bad idea), you can use:
pax> line=123456789abc
pax> line2=${line%%???}
pax> echo ${line2}
123456789
pax> _
You may also want to investigate whether you actually need a speed improvement. If you process the lines as one big chunk, you'll see that sed
is plenty fast. Type in the following:
#!/usr/bin/bash
echo This is a pretty chunky line with three bad characters at the end.XXX >qq1
for i in 4 16 64 256 1024 4096 16384 65536 ; do
cat qq1 qq1 >qq2
cat qq2 qq2 >qq1
done
head -20000l qq1 >qq2
wc -l qq2
date
time sed 's/...$//' qq2 >qq1
date
head -3l qq1
and run it. Here's the output on my (not very fast at all) R40 laptop:
pax> ./chk.sh
20000 qq2
Sat Jul 24 13:09:15 WAST 2010
real 0m0.851s
user 0m0.781s
sys 0m0.050s
Sat Jul 24 13:09:16 WAST 2010
This is a pretty chunky line with three bad characters at the end.
This is a pretty chunky line with three bad characters at the end.

That's 20,000 lines in under a second, pretty good for something that's only done every hour.
Eric's answer helpfully explains that the trouble comes from comparing a Pandas Series (containing a NumPy array) to a Python string. Unfortunately, his two workarounds both just suppress the warning.
To write code that doesn't cause the warning in the first place, explicitly compare your string to each element of the Series and get a separate bool for each. For example, you could use map
and an anonymous function.
myRows = df[df['Unnamed: 5'].map( lambda x: x == 'Peter' )].index.tolist()
import javax.xml.bind.DatatypeConverter;
public class f{
public static void main(String a[]){
String str = new String(DatatypeConverter.printBase64Binary(new String("user:123").getBytes()));
String res = DatatypeConverter.parseBase64Binary(str);
System.out.println(res);
}
}
When I faced this issue it was sorted out by using below mentioned steps:
Edit php.ini:
Make
;extension=php_intl.dll to
extension=php_intl.dll Simply copy all icu* * * *.dll files(any icu file with dll extension) from
C:\xampp\php to C:\xampp\apache\bin
Also If you have the msvcp110.dll missing file error. You have to download the right .dll or just go here http://www.microsoft.com/es-es/download/confirmation.aspx?id=30679 and install the vcredist_x64.exe and vcredist_x86.exe.
Now the intl extension should work :-)
You can use :nth-last-child()
; in fact, besides :nth-last-of-type()
I don't know what else you could use. I'm not sure what you mean by "dynamic", but if you mean whether the style applies to the new second last child when more children are added to the list, yes it will. Interactive fiddle.
ul li:nth-last-child(2)
Note that if you have table name with '_', it is removed in sequence name.
For example, table name: user_tokens column: id Sequence name: usertokens_id_seq
If you have
a=[[1,1],[2,1],[3,1]]
b=[[1,2],[2,2],[3,2]]
Then
a[1][1]
Will work fine. It points to the second column, second row just like you wanted.
I'm not sure what you did wrong.
To multiply the cells in the third column you can just do
c = [a[2][i] * b[2][i] for i in range(len(a[2]))]
Which will work for any number of rows.
Edit: The first number is the column, the second number is the row, with your current layout. They are both numbered from zero. If you want to switch the order you can do
a = zip(*a)
or you can create it that way:
a=[[1, 2, 3], [1, 1, 1]]
ProgressDialog is deprecated from Android Oreo. Use ProgressBar instead
ProgressDialog progress = new ProgressDialog(this);
progress.setTitle("Loading");
progress.setMessage("Wait while loading...");
progress.setCancelable(false); // disable dismiss by tapping outside of the dialog
progress.show();
// To dismiss the dialog
progress.dismiss();
OR
ProgressDialog.show(this, "Loading", "Wait while loading...");
By the way, Spinner has a different meaning in Android. (It's like the select dropdown in HTML)
may its so late but the response useful for others so :
Sometimes, when you don't specify a server or servlet container at the
creation of the project, NetBeans fails to create a context.xml
file.
META-INF
. Do this by right mouse button clicking on Web pages, and select:
New->Other->Other->File Folder
Name the folder META-INF
. Case is important, even on Windows.
context.xml
in the META-INF
folder. Do this by right mouse button clicking on the new META-INF
folder, and
select:
New->Other->XML->XML
Document
Name it context (NetBeans adds the .xml
)
Select Well-formed Document
Press Finish
Edit the new document (context.xml
), and add the following:
<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" path="/app-name"/>
Replace app-name with the name of your application.
Now your in-place deployment should work. If not, make sure that the file can be read by everyone.
The context.xml
file is specific to Tomcat. For more information about
that file, see the Tomcat documentation at tomcat.apache.org
.
Years later, but for what it's worth - This is simple to do.
Just RENAME the C:\xampp directory
Install the desired new version of XAMPP
Simply run the control panel script "xampp-control.exe" directly from within the xampp folder. (Ignore warnings about "must run from C:\xampp - those have nothing to do with multiple installations.)
To switch between these versions of XAMPP, just rename the xampp directories as necessary, and re-run.

The accepted answer doesn't provide a viable fix, and most of the other ones suggest the "triple-slashes" workaround which is not viable anymore, since the browser.d.ts
has been removed by the Angular2 latest RC's and thus is not available anymore.
I strongly suggest to install the typings
module as suggested by a couple solutions here, yet it's not necessary to do it manually or globally - there's an effective way to do that for your project only and within VS2015 interface. Here's what you need to do:
typings
in the project's package.json file.script
block in the package.json
file to execute/update typings
after each NPM action.typings.json
file in the project's root folder containing a reference to core-js
(overall better than es6-shim
atm).That's it.
You can also take a look to this other SO thread and/or read this post on my blog for additional details.
I vote for this 2:
string currentActionName = ViewContext.RouteData.GetRequiredString("action");
and
string currentViewName = ((WebFormView)ViewContext.View).ViewPath;
You can retrive both physical name of current view and action that triggered it. It can be usefull in partial *.acmx pages to determine host container.
You cannot do this on multiple fields. You can also look for this.
I dug into this and all the answers above are partially right. It all depends on how the container is launched. It comes down to the following when the container was launched:
-t
)-i
)^P^Q
does work, BUT only when -t
and -i
is used to launch the container:[berto@g6]$ docker run -ti -d --name test python:3.6 /bin/bash -c 'while [ 1 ]; do sleep 30; done;'
b26e39632351192a9a1a00ea0c2f3e10729b6d3e22f8e0676d6519e15c08b518
[berto@g6]$ docker attach test
# here I typed ^P^Q
read escape sequence
# i'm back to my prompt
[berto@g6]$ docker kill test; docker rm -v test
test
test
ctrl+c
does work, BUT only when -t
(without -i
) is used to launch the container:[berto@g6]$ docker run -t -d --name test python:3.6 /bin/bash -c 'while [ 1 ]; do sleep 30; done;'
018a228c96d6bf2e73cccaefcf656b02753905b9a859f32e60bdf343bcbe834d
[berto@g6]$ docker attach test
^C
[berto@g6]$
There is a way to detach without killing the container though; you need another shell. In summary, running this in another shell detached and left the container running pkill -9 -f 'docker.*attach'
:
[berto@g6]$ docker run -d --name test python:3.6 /bin/bash -c 'while [ 1 ]; do sleep 30; done;'
b26e39632351192a9a1a00ea0c2f3e10729b6d3e22f8e0676d6519e15c08b518
[berto@g6]$ docker attach test
# here I typed ^P^Q and doesn't work
^P
# ctrl+c doesn't work either
^C
# can't background either
^Z
# go to another shell and run the `pkill` command above
# i'm back to my prompt
[berto@g6]$
Why? Because you're killing the process that connected you to the container, not the container itself.
I think you want to change the setting called "DropDownStyle" to be "DropDownList".
Try this:
String LINK = "type_here_the_link";
setContentView(R.layout.mediaplayer);
VideoView videoView = (VideoView) findViewById(R.id.video);
MediaController mc = new MediaController(this);
mc.setAnchorView(videoView);
mc.setMediaPlayer(videoView);
Uri video = Uri.parse(LINK);
videoView.setMediaController(mc);
videoView.setVideoURI(video);
videoView.start();

Here's the documentation:
https://dev.mysql.com/doc/connector-j/en/connector-j-reference-configuration-properties.html
A basic connection string looks like:
jdbc:mysql://localhost:3306/dbname
The class.forName string is "com.mysql.jdbc.Driver", which you can find (edit: now on the same page).
You can use
sessionStorage.SessionName = "SessionData"
,
sessionStorage.getItem("SessionName")
and
sessionStorage.setItem("SessionName","SessionData");
See the supported browsers on http://caniuse.com/namevalue-storage
Consider the following example:
const foo = {};
foo[Symbol.toStringTag] = "bar";
console.log("" + foo);
Which outputs
[object bar]
Basically, any object in javascript can define a property with the tag Symbol.toStringTag
and override the output.
Behind the scenes construction of a new object in javascript prototypes from some object with a "toString" method. The default object provides this method as a property, and that method internally invokes the tag to determine how to coerce the object to a string. If the tag is present, then it's used, if missing you get "Object"
.
Should you set Symbol.toStringTag
? Maybe. But relying on the string always being [object Object]
for "true" objects is not the best idea.

Instead of Windows PowerShell
, find the item in the Start Menu called SharePoint 2013 Management Shell
:
Usually that will give you the top view, but there's no guarantee that it's visible to the user. It could be off the screen, have an alpha of 0.0, or could be have size of 0x0 for example.
It could also be that the keyWindow has no subviews, so you should probably test for that first. This would be unusual, but it's not impossible.
UIWindow is a subclass of UIView, so if you want to make sure your notification is visible to the user, you can add it directly to the keyWindow using addSubview:
and it will instantly be the top most view. I'm not sure if this is what you're looking to do though. (Based on your question, it looks like you already know this.)
I like to do it with a static method in the second activity:
private static final String EXTRA_GAME_ID = "your.package.gameId";
public static void start(Context context, String gameId) {
Intent intent = new Intent(context, SecondActivity.class);
intent.putExtra(EXTRA_GAME_ID, gameId);
context.startActivity(intent);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
...
Intent intent = this.getIntent();
String gameId = intent.getStringExtra(EXTRA_GAME_ID);
}
Then from your first activity (and for anywhere else), you just do:
SecondActivity.start(this, "the.game.id");
You can use max() to get the max value. The max function can also return the index of the maximum value in the vector. To get this, assign the result of the call to max to a two element vector instead of just a single variable.
e.g. z is your array,
>> [x, y] = max(z)
x =
7
y =
4
Here, 7 is the largest number at the 4th position(index).
I may have misunderstood the question(an example and a couple of surrounding lines would be nice), but why don't you always use an appropriate interface (and Java5+)? I see no reason why you would ever want to cast to a HashMap
instead of a Map<KeyType,ValueType>
. In fact, I can't imagine any reason to set the type of a variable to HashMap
instead of Map
.
And why is the source an Object
? Is it a parameter type of a legacy collection? If so, use generics and specify the type you want.
"bad enough not having a traditional for(;;) looper"?? What?
Are you trying to do
import string
for c in string.lowercase:
...do something with c...
Or perhaps you're using string.uppercase
or string.letters
?
Python doesn't have for(;;)
because there are often better ways to do it. It also doesn't have character math because it's not necessary, either.
The alert()
dialog is not rendered in HTML, and thus the HTML you have embedded is meaningless.
You'd need to use a custom modal to achieve that.
You seem to assign Double object into native double value field. Does that really compile?
Double.valueOf() creates a Double object so .doubleValue() should not be necessary.
If you want native double field, you need to define the field as double and then use .doubleValue()
It's your choice. There are basically three ways in a Java web application archive (WAR):
So that you can load it by ClassLoader#getResourceAsStream()
with a classpath-relative path:
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
InputStream input = classLoader.getResourceAsStream("foo.properties");
// ...
Properties properties = new Properties();
properties.load(input);
Here foo.properties
is supposed to be placed in one of the roots which are covered by the default classpath of a webapp, e.g. webapp's /WEB-INF/lib
and /WEB-INF/classes
, server's /lib
, or JDK/JRE's /lib
. If the propertiesfile is webapp-specific, best is to place it in /WEB-INF/classes
. If you're developing a standard WAR project in an IDE, drop it in src
folder (the project's source folder). If you're using a Maven project, drop it in /main/resources
folder.
You can alternatively also put it somewhere outside the default classpath and add its path to the classpath of the appserver. In for example Tomcat you can configure it as shared.loader
property of Tomcat/conf/catalina.properties
.
If you have placed the foo.properties
it in a Java package structure like com.example
, then you need to load it as below
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
InputStream input = classLoader.getResourceAsStream("com/example/foo.properties");
// ...
Note that this path of a context class loader should not start with a /
. Only when you're using a "relative" class loader such as SomeClass.class.getClassLoader()
, then you indeed need to start it with a /
.
ClassLoader classLoader = getClass().getClassLoader();
InputStream input = classLoader.getResourceAsStream("/com/example/foo.properties");
// ...
However, the visibility of the properties file depends then on the class loader in question. It's only visible to the same class loader as the one which loaded the class. So, if the class is loaded by e.g. server common classloader instead of webapp classloader, and the properties file is inside webapp itself, then it's invisible. The context class loader is your safest bet so you can place the properties file "everywhere" in the classpath and/or you intend to be able to override a server-provided one from the webapp on.
So that you can load it by ServletContext#getResourceAsStream()
with a webcontent-relative path:
InputStream input = getServletContext().getResourceAsStream("/WEB-INF/foo.properties");
// ...
Note that I have demonstrated to place the file in /WEB-INF
folder, otherwise it would have been public accessible by any webbrowser. Also note that the ServletContext
is in any HttpServlet
class just accessible by the inherited GenericServlet#getServletContext()
and in Filter
by FilterConfig#getServletContext()
. In case you're not in a servlet class, it's usually just injectable via @Inject
.
So that you can load it the usual java.io
way with an absolute local disk file system path:
InputStream input = new FileInputStream("/absolute/path/to/foo.properties");
// ...
Note the importance of using an absolute path. Relative local disk file system paths are an absolute no-go in a Java EE web application. See also the first "See also" link below.
Just weigh the advantages/disadvantages in your own opinion of maintainability.
If the properties files are "static" and never needs to change during runtime, then you could keep them in the WAR.
If you prefer being able to edit properties files from outside the web application without the need to rebuild and redeploy the WAR every time, then put it in the classpath outside the project (if necessary add the directory to the classpath).
If you prefer being able to edit properties files programmatically from inside the web application using Properties#store()
method, put it outside the web application. As the Properties#store()
requires a Writer
, you can't go around using a disk file system path. That path can in turn be passed to the web application as a VM argument or system property. As a precaution, never use getRealPath()
. All changes in deploy folder will get lost on a redeploy for the simple reason that the changes are not reflected back in original WAR file.
This is because of implicit conversion. The variables b, c, d
are of float
type. But the /
operator sees two integers it has to divide and hence returns an integer in the result which gets implicitly converted to a float
by the addition of a decimal point. If you want float divisions, try making the two operands to the /
floats. Like follows.
#include <stdio.h>
int main() {
int a;
float b, c, d;
a = 750;
b = a / 350.0f;
c = 750;
d = c / 350;
printf("%.2f %.2f", b, d);
// output: 2.14 2.14
return 0;
}
UPDATE: The code below has a bug, described here. The test program below works, but if you were to use DayOfWeek.Mon (for example) before DayOfWeek itself, it would fail because DayOfWeek has not been initialized (use of an inner object does not cause an outer object to be initialized). You can still use this code if you do something like val enums = Seq( DayOfWeek )
in your main class, forcing initialization of your enums, or you can use chaotic3quilibrium's modifications. Looking forward to a macro-based enum!
If you want
then the following may be of interest. Feedback welcome.
In this implementation there are abstract Enum and EnumVal base classes, which you extend. We'll see those classes in a minute, but first, here's how you would define an enum:
object DayOfWeek extends Enum {
sealed abstract class Val extends EnumVal
case object Mon extends Val; Mon()
case object Tue extends Val; Tue()
case object Wed extends Val; Wed()
case object Thu extends Val; Thu()
case object Fri extends Val; Fri()
case object Sat extends Val; Sat()
case object Sun extends Val; Sun()
}
Note that you have to use each enum value (call its apply method) to bring it to life. [I wish inner objects weren't lazy unless I specifically ask for them to be. I think.]
We could of course add methods/data to DayOfWeek, Val, or the individual case objects if we so desired.
And here's how you would use such an enum:
object DayOfWeekTest extends App {
// To get a map from Int id to enum:
println( DayOfWeek.valuesById )
// To get a map from String name to enum:
println( DayOfWeek.valuesByName )
// To iterate through a list of the enum values in definition order,
// which can be made different from ID order, and get their IDs and names:
DayOfWeek.values foreach { v => println( v.id + " = " + v ) }
// To sort by ID or name:
println( DayOfWeek.values.sorted mkString ", " )
println( DayOfWeek.values.sortBy(_.toString) mkString ", " )
// To look up enum values by name:
println( DayOfWeek("Tue") ) // Some[DayOfWeek.Val]
println( DayOfWeek("Xyz") ) // None
// To look up enum values by id:
println( DayOfWeek(3) ) // Some[DayOfWeek.Val]
println( DayOfWeek(9) ) // None
import DayOfWeek._
// To compare enums as ordinals:
println( Tue < Fri )
// Warnings about non-exhaustive pattern matches:
def aufDeutsch( day: DayOfWeek.Val ) = day match {
case Mon => "Montag"
case Tue => "Dienstag"
case Wed => "Mittwoch"
case Thu => "Donnerstag"
case Fri => "Freitag"
// Commenting these out causes compiler warning: "match is not exhaustive!"
// case Sat => "Samstag"
// case Sun => "Sonntag"
}
}
Here's what you get when you compile it:
DayOfWeekTest.scala:31: warning: match is not exhaustive!
missing combination Sat
missing combination Sun
def aufDeutsch( day: DayOfWeek.Val ) = day match {
^
one warning found
You can replace "day match" with "( day: @unchecked ) match" where you don't want such warnings, or simply include a catch-all case at the end.
When you run the above program, you get this output:
Map(0 -> Mon, 5 -> Sat, 1 -> Tue, 6 -> Sun, 2 -> Wed, 3 -> Thu, 4 -> Fri)
Map(Thu -> Thu, Sat -> Sat, Tue -> Tue, Sun -> Sun, Mon -> Mon, Wed -> Wed, Fri -> Fri)
0 = Mon
1 = Tue
2 = Wed
3 = Thu
4 = Fri
5 = Sat
6 = Sun
Mon, Tue, Wed, Thu, Fri, Sat, Sun
Fri, Mon, Sat, Sun, Thu, Tue, Wed
Some(Tue)
None
Some(Thu)
None
true
Note that since the List and Maps are immutable, you can easily remove elements to create subsets, without breaking the enum itself.
Here is the Enum class itself (and EnumVal within it):
abstract class Enum {
type Val <: EnumVal
protected var nextId: Int = 0
private var values_ = List[Val]()
private var valuesById_ = Map[Int ,Val]()
private var valuesByName_ = Map[String,Val]()
def values = values_
def valuesById = valuesById_
def valuesByName = valuesByName_
def apply( id : Int ) = valuesById .get(id ) // Some|None
def apply( name: String ) = valuesByName.get(name) // Some|None
// Base class for enum values; it registers the value with the Enum.
protected abstract class EnumVal extends Ordered[Val] {
val theVal = this.asInstanceOf[Val] // only extend EnumVal to Val
val id = nextId
def bumpId { nextId += 1 }
def compare( that:Val ) = this.id - that.id
def apply() {
if ( valuesById_.get(id) != None )
throw new Exception( "cannot init " + this + " enum value twice" )
bumpId
values_ ++= List(theVal)
valuesById_ += ( id -> theVal )
valuesByName_ += ( toString -> theVal )
}
}
}
And here is a more advanced use of it which controls the IDs and adds data/methods to the Val abstraction and to the enum itself:
object DayOfWeek extends Enum {
sealed abstract class Val( val isWeekday:Boolean = true ) extends EnumVal {
def isWeekend = !isWeekday
val abbrev = toString take 3
}
case object Monday extends Val; Monday()
case object Tuesday extends Val; Tuesday()
case object Wednesday extends Val; Wednesday()
case object Thursday extends Val; Thursday()
case object Friday extends Val; Friday()
nextId = -2
case object Saturday extends Val(false); Saturday()
case object Sunday extends Val(false); Sunday()
val (weekDays,weekendDays) = values partition (_.isWeekday)
}
In order to avoid this kind of ClassCastException, if you have:
class A
class B extends A
You can define a constructor in B that takes an object of A. This way we can do the "cast" e.g.:
public B(A a) {
super(a.arg1, a.arg2); //arg1 and arg2 must be, at least, protected in class A
// If B class has more attributes, then you would initilize them here
}
For MySQL, this can be shortened to:
SELECT distributor_id,
COUNT(*) total,
SUM(level = 'exec') ExecCount,
SUM(level = 'personal') PersonalCount
FROM yourtable
GROUP BY distributor_id
To add a header just add the following code to the location block where you want to add the header:
location some-location {
add_header X-my-header my-header-content;
}
Obviously, replace the x-my-header and my-header-content with what you want to add. And that's all there is to it.
My problem was that I had the Server service stopped and this gave exactly this same issue. So started the Server service and the installation worked.
Contrary to some of the other answers here, I say that you can use tabs however you want. vim was designed to be versatile and customizable, rather than forcing you to work according to predefined parameters. We all know how us programmers love to impose our "ethics" on everyone else, so this achievement is certainly a primary feature.
<C-w>gf
is the tab equivalent of buffers' gf
command. <C-PageUp>
and <C-PageDown>
will switch between tabs. (In Byobu, these two commands never work for me, but they work outside of Byobu/tmux. Alternatives are gt
and gT
.) <C-w>T
will move the current window to a new tab page.
If you'd prefer that vim use an existing tab if possible, rather than creating a duplicate tab, add :set switchbuf=usetab
to your .vimrc file. You can add newtab
to the list (:set switchbuf=usetab,newtab
) to force QuickFix commands that display compile errors to open in separate tabs. I prefer split
instead, which opens the compile errors in a split window.
If you have mouse support enabled with :set mouse=a
, you can interact with the tabs by clicking on them. There's also a +
button by default that will create a new tab.
For the documentation on tabs, type :help tab-page
in normal mode. (After you do that, you can practice moving a window to a tab using <C-w>T
.) There's a long list of commands. Some of the window commands have to do with tabs, so you might want to look at that documentation as well via :help windows
.
Addition: 2013-12-19
To open multiple files in vim with each file in a separate tab, use vim -p file1 file2 ...
. If you're like me and always forget to add -p
, you can add it at the end, as vim follows the normal command line option parsing rules. Alternatively, you can add a bash alias mapping vim
to vim -p
.
The best approach is Long.valueOf(str)
as it relies on Long.valueOf(long)
which uses an internal cache making it more efficient since it will reuse if needed the cached instances of Long
going from -128
to 127
included.
Returns a
Long
instance representing the specified long value. If a new Long instance is not required, this method should generally be used in preference to the constructorLong(long)
, as this method is likely to yield significantly better space and time performance by caching frequently requested values. Note that unlike the corresponding method in the Integer class, this method is not required to cache values within a particular range.
Thanks to auto-unboxing allowing to convert a wrapper class's instance into its corresponding primitive type, the code would then be:
long val = Long.valueOf(str);
Please note that the previous code can still throw a NumberFormatException
if the provided String
doesn't match with a signed long
.
Generally speaking, it is a good practice to use the static
factory method valueOf(str)
of a wrapper class like Integer
, Boolean
, Long
, ... since most of them reuse instances whenever it is possible making them potentially more efficient in term of memory footprint than the corresponding parse
methods or constructors.
Excerpt from Effective Java Item 1
written by Joshua Bloch:
You can often avoid creating unnecessary objects by using static factory methods (Item 1) in preference to constructors on immutable classes that provide both. For example, the static factory method
Boolean.valueOf(String)
is almost always preferable to the constructorBoolean(String)
. The constructor creates a new object each time it’s called, while the static factory method is never required to do so and won’t in practice.
Inspired by this very post, I now use a handy function,
reproduce(<mydata>)
when I need to post to StackOverflow.
If myData
is the name of your object to reproduce, run the following in R:
install.packages("devtools")
library(devtools)
source_url("https://raw.github.com/rsaporta/pubR/gitbranch/reproduce.R")
reproduce(myData)
This function is an intelligent wrapper to dput
and does the following:
dput
outputobjName <- ...
so that it can be easily copy+pasted, but...# sample data
DF <- data.frame(id=rep(LETTERS, each=4)[1:100], replicate(100, sample(1001, 100)), Class=sample(c("Yes", "No"), 100, TRUE))
DF is about 100 x 102. I want to sample 10 rows and a few specific columns
reproduce(DF, cols=c("id", "X1", "X73", "Class")) # I could also specify the column number.
This is what the sample looks like:
id X1 X73 Class
1 A 266 960 Yes
2 A 373 315 No Notice the selection split
3 A 573 208 No (which can be turned off)
4 A 907 850 Yes
5 B 202 46 Yes
6 B 895 969 Yes <~~~ 70 % of selection is from the top rows
7 B 940 928 No
98 Y 371 171 Yes
99 Y 733 364 Yes <~~~ 30 % of selection is from the bottom rows.
100 Y 546 641 No

Notice also that the entirety of the output is in a nice single, long line, not a tall paragraph of chopped up lines. This makes it easier to read on SO questions posts and also easier to copy+paste.
You can now specify how many lines of text output will take up (ie, what you will paste into StackOverflow). Use the lines.out=n
argument for this. Example:

According to the Wikipedia Article on Favicon, Internet Explorer supports only the ICO format for favicons.
I would stick with two different icons.
Half a decade later we have a built-in way for it! For modern browsers I would use:
const tz = Intl.DateTimeFormat().resolvedOptions().timeZone;_x000D_
console.log(tz);
_x000D_
This returns a IANA timezone string, but not the offset. Learn more at the MDN reference.
Compatibility table - as of March 2019, works for 90% of the browsers in use globally. Doesn't work on Internet Explorer.

chenzj/dfimage - as described on hub.docker.com regenerates Dockerfile from other images. So you can use it as follows:
docker pull chenzj/dfimage
alias dfimage="docker run -v /var/run/docker.sock:/var/run/docker.sock --rm chenzj/dfimage"
dfimage IMAGE_ID > Dockerfile
According to MDN, the difference is as below:
addEventListener:
The EventTarget.addEventListener() method adds the specified EventListener-compatible object to the list of event listeners for the specified event type on the EventTarget on which it's called. The event target may be an Element in a document, the Document itself, a Window, or any other object that supports events (such as XMLHttpRequest).
onclick:
The onclick property returns the click event handler code on the current element. When using the click event to trigger an action, also consider adding this same action to the keydown event, to allow the use of that same action by people who don't use a mouse or a touch screen. Syntax element.onclick = functionRef; where functionRef is a function - often a name of a function declared elsewhere or a function expression. See "JavaScript Guide:Functions" for details.
There is also a syntax difference in use as you see in the below codes:
addEventListener:
// Function to change the content of t2
function modifyText() {
var t2 = document.getElementById("t2");
if (t2.firstChild.nodeValue == "three") {
t2.firstChild.nodeValue = "two";
} else {
t2.firstChild.nodeValue = "three";
}
}
// add event listener to table
var el = document.getElementById("outside");
el.addEventListener("click", modifyText, false);
onclick:
function initElement() {
var p = document.getElementById("foo");
// NOTE: showAlert(); or showAlert(param); will NOT work here.
// Must be a reference to a function name, not a function call.
p.onclick = showAlert;
};
function showAlert(event) {
alert("onclick Event detected!");
}
In my deployment I can't use app.config neither to embed what Andrew Webb suggested.
So I'm doing this:
IWebProxy proxy = WebRequest.GetSystemWebProxy();
proxy.Credentials = CredentialCache.DefaultCredentials;
WebClient wc = new WebClient();
wc.UseDefaultCredentials = true;
wc.Proxy = proxy;
Just in case you want to check my IE settings:
Try this
After selecting a block of text, press Shift+i or capital I.
Lowercase i will not work.
Then type the things you want and finally to apply it to all lines, press Esc twice.
If this doesn't work...
Check if you have +visualextra
enabled in your version of Vim.
You can do this by typing in :ver
and scrolling through the list of features. (You might want to copy and paste it into a buffer and do incremental search because the format is odd.)
Enabling it is outside the scope of this question but I'm sure you can find it somewhere.
You can try this
pid=$(ps -o pid=,comm= | grep -m1 $procname | cut -d' ' -f1)
I had this issue with MacOS High Sierria.
You can set up locale as well as language to UTF-8 format using below command :
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
Now in order to check whether locale environment is updated use below command :
Locale
This is the code I'm using:
private static byte[] xor(final byte[] input, final byte[] secret) {
final byte[] output = new byte[input.length];
if (secret.length == 0) {
throw new IllegalArgumentException("empty security key");
}
int spos = 0;
for (int pos = 0; pos < input.length; ++pos) {
output[pos] = (byte) (input[pos] ^ secret[spos]);
++spos;
if (spos >= secret.length) {
spos = 0;
}
}
return output;
}
Not an expert on encoding, but after reading these...
... it seems fairly clear that the $OutputEncoding variable only affects data piped to native applications.
If sending to a file from withing PowerShell, the encoding can be controlled by the -encoding
parameter on the out-file
cmdlet e.g.
write-output "hello" | out-file "enctest.txt" -encoding utf8
Nothing else you can do on the PowerShell front then, but the following post may well help you:.
@jim's answer is correct -- fuser
is what you want.
Additionally (or alternately), you can use lsof
to get more information including the username, in case you need permission (without having to run an additional command) to kill the process. (THough of course, if killing the process is what you want, fuser
can do that with its -k
option. You can have fuser
use other signals with the -s
option -- check the man page for details.)
For example, with a tail -F /etc/passwd
running in one window:
ghoti@pc:~$ lsof | grep passwd
tail 12470 ghoti 3r REG 251,0 2037 51515911 /etc/passwd
Note that you can also use lsof
to find out what processes are using particular sockets. An excellent tool to have in your arsenal.
Try this one:
let uuid = NSUUID().uuidString
print(uuid)
Swift 3/4/5
let uuid = UUID().uuidString
print(uuid)
You should just use "+" before $(this)
. That's going to convert the string to number, so:
var votevalue = +$(this).data('votevalue');
Oh and I recommend to use closest()
method just in case :)
var votevalue = +$(this).closest('.btn-group').data('votevalue');
@InjectMocks annotation can be used to inject mock fields into a test object automatically.
In below example @InjectMocks has used to inject the mock dataMap into the dataLibrary .
@Mock
Map<String, String> dataMap ;
@InjectMocks
DataLibrary dataLibrary = new DataLibrary();
@Test
public void whenUseInjectMocksAnnotation_() {
Mockito.when(dataMap .get("aData")).thenReturn("aMeaning");
assertEquals("aMeaning", dataLibrary .getMeaning("aData"));
}
one of the Easy Way for Encode Or Decode HTML-entities
just Call a Function with one argument...
Decode HTML-entities
function decodeHTMLEntities(text) {
var textArea = document.createElement('textarea');
textArea.innerHTML = text;
return textArea.value;
}
Decode HTML-entities (JQuery)
function decodeHTMLEntities(text) {
return $("<textarea/>").html(text).text();
}
Encode HTML-entities
function encodeHTMLEntities(text) {
var textArea = document.createElement('textarea');
textArea.innerText = text;
return textArea.innerHTML;
}
Encode HTML-entities (JQuery)
function encodeHTMLEntities(text) {
return $("<textarea/>").text(text).html();
}
I had the same problem after reinstalled my android studio. Here's what I did to make my adb work again:
-path to C:\Users\User\AppData\Local\Android\sdk\platform-tools
-Shift+r.click and start command from here instead.
set TEXT_T="myfile.txt"
set /a c=1
FOR /F "tokens=1 usebackq" %%i in (%TEXT_T%) do (
set /a c+=1
set OUTPUT_FILE_NAME=output_%c%.txt
echo Output file is %OUTPUT_FILE_NAME%
echo %%i, %c%
)
If you want to include a zoom level, you can use this format:

For a quick and cheap way to host an angular app, I have been using the Firbase hosting. It's free on the first tier and very easy to deploy new versions using the Firebase CLI. This article here explains the necessary steps to deploy your production angular 2 app to Firebase: https://medium.com/codingthesmartway-com-blog/hosting-angular-2-applications-on-firebase-f194688c978d
In short, you run ng build --prod
which creates a dist folder in the package and that's the folder that gets deployed to Firebase Hosting.
You could use .gitignore
to keep the config.xml
out of the repository, and then use a post commit hook to upload the appropriate config.xml
file to the server.
You just need to get selenium package imported, that you can do from command prompt using the command
pip install selenium
When you have to use it in any IDE just import this package, no other documentation required to be imported
For Eg :
import selenium
print(selenium.__filepath__)
This is just a general command you may use in starting to check the filepath of selenium
This should do what you want.
public function up()
{
DB::table('user')->insert(array('username'=>'dude', 'password'=>'z19pers!'));
}
If you can't assume that all the strings you process have double quotes you can use something like this:
if string.startswith('"') and string.endswith('"'):
string = string[1:-1]
Edit:
I'm sure that you just used string
as the variable name for exemplification here and in your real code it has a useful name, but I feel obliged to warn you that there is a module named string
in the standard libraries. It's not loaded automatically, but if you ever use import string
make sure your variable doesn't eclipse it.
Looking at your output maybe the following query can work, give it a try:
SELECT * FROM tablename
WHERE id IN
(SELECT MIN(id) FROM tablename GROUP BY EmailAddress)
This will select only one row for each distinct email address, the row with the minimum id
which is what your result seems to portray
You're correct. Subdomains are still considered separate domains when using iframes. It's possible to pass messages using postMessage(...)
, but other JS APIs are intentionally made inaccessible.
It's also still possible to get the URL depending on the context. See other answers for more details.
gzip -dc archive.tar.gz | tar -xf - -C /destination
or, with GNU tar
tar xzf archive.tar.gz -C /destination
The reason is old rubygems. You need to update system part using non ssl source first:
gem update --system --source http://rubygems.org/
(temporarily updating system part using non-ssl connection).
Now you're ready to use gem update
.
public class **Your java Class** extends ActionBarActivity implements View.OnClickListener{
date = (EditText) findViewById(R.id.date);
date.setInputType(InputType.TYPE_NULL);
date.requestFocus();
date.setOnClickListener(this);
dateFormatter = new SimpleDateFormat("yyyy-MM-dd", Locale.US);
setDateTimeField();
private void setDateTimeField() {
Calendar newCalendar = Calendar.getInstance();
fromDatePickerDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Calendar newDate = Calendar.getInstance();
newDate.set(year, monthOfYear, dayOfMonth);
date.setText(dateFormatter.format(newDate.getTime()));
}

The following code will create a list of files based on the accept method of the FileNameFilter
.
List<File> list = Arrays.asList(dir.listFiles(new FilenameFilter(){
@Override
public boolean accept(File dir, String name) {
return name.endsWith(".exe"); // or something else
}}));
In rare cases, npm cache may get corrupt. For me, what worked was:
npm cache clean --force
Generally, the package manager will detect corruption and refetch on its own so this is not usually necessary. However, in my case Windows 10 crashed a few times and I suspect this may have been during a fetch operation. Hope it helps someone!
More information: https://docs.npmjs.com/cli/cache
just parse as an array:
Review[] reviews = new Gson().fromJson(jsonString, Review[].class);
then if you need you can also create a list in this way:
List<Review> asList = Arrays.asList(reviews);
P.S. your json string should be look like this:
[
{
"reviewerID": "A2SUAM1J3GNN3B1",
"asin": "0000013714",
"reviewerName": "J. McDonald",
"helpful": [2, 3],
"reviewText": "I bought this for my husband who plays the piano.",
"overall": 5.0,
"summary": "Heavenly Highway Hymns",
"unixReviewTime": 1252800000,
"reviewTime": "09 13, 2009"
},

"reviewTime": "09 13, 2009"
},
[...]
]
The another workaround is to call
Hibernate.initialize(extractedObject.getSubojbectToUnproxy());
Just before closing the session.

Sadly, elements of the enum are 'global'. You access them by doing day = Saturday
. That means that you cannot have enum A { a, b } ;
and enum B { b, a } ;
for they are in conflict.
Have you tried using str.splitlines()
method?:
From the docs:
Return a list of the lines in the string, breaking at line boundaries. Line breaks are not included in the resulting list unless
keepends
is given and true.
For example:
>>> 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines()
['Line 1', '', 'Line 3', 'Line 4']
>>> 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines(True)
['Line 1\n', '\n', 'Line 3\r', 'Line 4\r\n']
This method uses the universal newlines approach to splitting lines.
The main difference between Python 2.X
and Python 3.X
is that the former uses the universal newlines approach to splitting lines, so "\r"
, "\n"
, and "\r\n"
are considered line boundaries for 8-bit strings, while the latter uses a superset of it that also includes:
\v
or \x0b
: Line Tabulation (added in Python 3.2
).\f
or \x0c
: Form Feed (added in Python 3.2
).\x1c
: File Separator.\x1d
: Group Separator.\x1e
: Record Separator.\x85
: Next Line (C1 Control Code).\u2028
: Line Separator.\u2029
: Paragraph Separator.Unlike
str.split()
when a delimiter string sep is given, this method returns an empty list for the empty string, and a terminal line break does not result in an extra line:
>>> ''.splitlines()
[]
>>> 'Line 1\n'.splitlines()
['Line 1']
While str.split('\n')
returns:
>>> ''.split('\n')
['']
>>> 'Line 1\n'.split('\n')
['Line 1', '']
If you also need to remove additional leading or trailing whitespace, like spaces, that are ignored by str.splitlines()
, you could use str.splitlines()
together with str.strip()
:
>>> [str.strip() for str in 'Line 1 \n \nLine 3 \rLine 4 \r\n'.splitlines()]
['Line 1', '', 'Line 3', 'Line 4']
Lastly, if you want to filter out the empty strings from the resulting list, you could use filter()
:
>>> # Python 2.X:
>>> filter(bool, 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines())
['Line 1', 'Line 3', 'Line 4']
>>> # Python 3.X:
>>> list(filter(bool, 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines()))
['Line 1', 'Line 3', 'Line 4']
As the error you posted indicates and Burhan suggested, the problem is from the print. There's a related question about that could be useful to you: UnicodeEncodeError: 'charmap' codec can't encode - character maps to <undefined>, print function

method through props.

Both of the examples immediately above didn't work for me. Opening a recordset on the table and adding a record does work to add the record, except:
myLong = CLng(rs!AutoNumberField)
returns Null if put between rs.AddNew and rs.Update. If put after rs.Update, it does return something, but it's always wrong, and always the same incorrect value. Looking at the table directly after adding the new record shows an autonumber field value different than the one returned by the above statement.
myLong = DLookup("AutoNumberField","TableName","SomeCriteria")
will work properly, as long as it's done after rs.Update, and there are any other fields which can uniquely identify the record.
I couldn't resolve this method (admittedly I didn't search for long)
mongoose.mongo.BSONPure.ObjectID.fromHexString
If your schema expects the property to be of type ObjectId, the conversion is implicit, at least this seems to be the case in 4.7.8.
You could use something like this however, which gives a bit more flex:
function toObjectId(ids) {
if (ids.constructor === Array) {
return ids.map(mongoose.Types.ObjectId);
}
return mongoose.Types.ObjectId(ids);
}
Use the after
method on the Tk
object:
from tkinter import *
root = Tk()
def task():
print("hello")
root.after(2000, task) # reschedule event in 2 seconds
root.after(2000, task)
root.mainloop()
Here's the declaration and documentation for the after
method:
def after(self, ms, func=None, *args):
"""Call function once after given time.
MS specifies the time in milliseconds. FUNC gives the
function which shall be called. Additional parameters
are given as parameters to the function call. Return
identifier to cancel scheduling with after_cancel."""
Because the numbers after point is only zero, the best solution is to use the Math.Round(MyNumber)
StreamSaver is an alternative to save very large files without having to keep all data in the memory.
In fact it emulates everything the server dose when saving a file but all client side with service worker.
You can either get the writer and manually write Uint8Array's to it or pipe a binary readableStream to the writable stream
There is a few example showcasing:
Response
or blob.stream()
to StreamSaverHere is an example in it's simplest form:
const fileStream = streamSaver.createWriteStream('filename.txt')
new Response('StreamSaver is awesome').body
.pipeTo(fileStream)
.then(success, error)
If you want to save a blob you would just convert that to a readableStream
new Response(blob).body.pipeTo(...) // response hack
blob.stream().pipeTo(...) // feature reference
You will get this error when you call any of the setXxx()
methods on PreparedStatement
, while the SQL query string does not have any placeholders ?
for this.
For example this is wrong:
String sql = "INSERT INTO tablename (col1, col2, col3) VALUES (val1, val2, val3)";
// ...
preparedStatement = connection.prepareStatement(sql);
preparedStatement.setString(1, val1); // Fail.
preparedStatement.setString(2, val2);
preparedStatement.setString(3, val3);
You need to fix the SQL query string accordingly to specify the placeholders.
String sql = "INSERT INTO tablename (col1, col2, col3) VALUES (?, ?, ?)";
// ...
preparedStatement = connection.prepareStatement(sql);
preparedStatement.setString(1, val1);
preparedStatement.setString(2, val2);
preparedStatement.setString(3, val3);
Note the parameter index starts with 1
and that you do not need to quote those placeholders like so:
String sql = "INSERT INTO tablename (col1, col2, col3) VALUES ('?', '?', '?')";
Otherwise you will still get the same exception, because the SQL parser will then interpret them as the actual string values and thus can't find the placeholders anymore.
If you just want to filter null values out of a stream, you can simply use a method reference to java.util.Objects.nonNull(Object). From its documentation:
This method exists to be used as a Predicate,
filter(Objects::nonNull)
For example:
List<String> list = Arrays.asList( null, "Foo", null, "Bar", null, null);
list.stream()
.filter( Objects::nonNull ) // <-- Filter out null values
.forEach( System.out::println );
This will print:
Foo
Bar
I use both PuTTY and Bitvise SSH Client. PuTTY handles screen sessions better, but Bitvise automatically opens up a SFTP window so you can transfer files just like you would with an FTP client.
I have added the following line to my /etc/mysql/my.cnf
file:
default_time_zone='+00:00'
Restarted the MySQL server:
systemctl restart mysql
And it works like a charm.
This problem also occurs if you don't include your controller class for compile-process in the .csproj files.
<Compile Include="YOUR_CONTROLLER_PATH.cs" />
Simply -> they provide True/False values based on condition mostly used for querying. mostly used with delegates
consider example of list
List<Program> blabla= new List<Program>();
blabla.Add(new Program("shubham", 1));
blabla.Add(new Program("google", 3));
blabla.Add(new Program("world",5));
blabla.Add(new Program("hello", 5));
blabla.Add(new Program("bye", 2));
contains names and ages. Now say we want to find names on condition So I Will use,
Predicate<Program> test = delegate (Program p) { return p.age > 3; };
List<Program> matches = blabla.FindAll(test);
Action<Program> print = Console.WriteLine;
matches.ForEach(print);
tried to Keep it Simple!
LinearLayout layout = (LinearLayout)findViewById(R.id.layout);
View child = getLayoutInflater().inflate(R.layout.child, null);
layout.addView(child);
You really should have multiple input, e.g. one for firstname, middle names, lastname and another one for age. If you want to have some fun though you could try:
>>> input_given="join smith 25"
>>> chars="".join([i for i in input_given if not i.isdigit()])
>>> age=input_given.translate(None,chars)
>>> age
'25'
>>> name=input_given.replace(age,"").strip()
>>> name
'join smith'
This would of course fail if there is multiple numbers in the input. a quick check would be:
assert(age in input_given)
and also:
assert(len(name)<len(input_given))
org.postgresql.util.PSQLException: FATAL: sorry, too many clients already.
Summary:
You opened up more than the allowed limit of connections to the database. You ran something like this: Connection conn = myconn.Open();
inside of a loop, and forgot to run conn.close();
. Just because your class is destroyed and garbage collected does not release the connection to the database. The quickest fix to this is to make sure you have the following code with whatever class that creates a connection:
protected void finalize() throws Throwable
{
try { your_connection.close(); }
catch (SQLException e) {
e.printStackTrace();
}
super.finalize();
}
Place that code in any class where you create a Connection. Then when your class is garbage collected, your connection will be released.
Run this SQL to see postgresql max connections allowed:
show max_connections;
The default is 100. PostgreSQL on good hardware can support a few hundred connections at a time. If you want to have thousands, you should consider using connection pooling software to reduce the connection overhead.
Take a look at exactly who/what/when/where is holding open your connections:
SELECT * FROM pg_stat_activity;
The number of connections currently used is:
SELECT COUNT(*) from pg_stat_activity;
Debugging strategy
You could give different usernames/passwords to the programs that might not be releasing the connections to find out which one it is, and then look in pg_stat_activity to find out which one is not cleaning up after itself.
Do a full exception stack trace when the connections could not be created and follow the code back up to where you create a new Connection
, make sure every code line where you create a connection ends with a connection.close();
How to set the max_connections higher:
max_connections in the postgresql.conf sets the maximum number of concurrent connections to the database server.
SHOW config_file;
/var/lib/pgsql/data/postgresql.conf
max_connections=100
.What's the maximum max_connections?
Use this query:
select min_val, max_val from pg_settings where name='max_connections';
I get the value 8388607
, in theory that's the most you are allowed to have, but then a runaway process can eat up thousands of connections, and surprise, your database is unresponsive until reboot. If you had a sensible max_connections like 100. The offending program would be denied a new connection.
List of time zone identifiers, included by default in Windows XP and Vista: Finding the Time Zones Defined on a Local System
Number of a columns in the result set you can get with code (as DB is used PostgreSQL):
//load the driver for PostgreSQL Class.forName("org.postgresql.Driver"); String url = "jdbc:postgresql://localhost/test"; Properties props = new Properties(); props.setProperty("user","mydbuser"); props.setProperty("password","mydbpass"); Connection conn = DriverManager.getConnection(url, props); //create statement Statement stat = conn.createStatement(); //obtain a result set ResultSet rs = stat.executeQuery("SELECT c1, c2, c3, c4, c5 FROM MY_TABLE"); //from result set give metadata ResultSetMetaData rsmd = rs.getMetaData(); //columns count from metadata object int numOfCols = rsmd.getColumnCount();
But you can get more meta-informations about columns:
for(int i = 1; i <= numOfCols; i++)
{
System.out.println(rsmd.getColumnName(i));
}
And at least but not least, you can get some info not just about table but about DB too, how to do it you can find here and here.
In case anybody else comes across this problem, as I just have, the answer is to wrap the content which you want to collapse inside a div
and collapse the wrapper div rather than the content itself.

In python 2 only (not python 3):

Is actually what you want, otherwise you'll miss out on a lot of things which act like lists, but aren't subclasses of list
or tuple
.
Have your tried json-io (https://github.com/jdereg/json-io)?
This library allows you to serialize / deserialize any Java object graph, including object graphs with cycles in them (e.g., A->B, B->A). It does not require your classes to implement any particular interface or inherit from any particular Java class.
In addition to serialization of Java to JSON (and JSON to Java), you can use it to format (pretty print) JSON:
String niceFormattedJson = JsonWriter.formatJson(jsonString)
If you just want the anchor color to stay the same as the anchor's parent element you can leverage inherit:
a, a:visited, a:hover, a:active {
color: inherit;
}
Notice there is no need to repeat the rule for each selector; just use a comma separated list of selectors (order matters for anchor pseudo elements). Also, you can apply the pseudo selectors to a class if you want to selectively disable the special anchor colors:
.special-link, .special-link:visited, .special-link:hover, .special-link:active {
color: inherit;
}
Your question only asks about the visited state, but I assumed you meant all of the states. You can remove the other selectors if you want to allow color changes on all but visited.
For Chrome via Chrome Fullscreen API
Note that for (Chrome) security reasons it cannot be called or executed automatically, there must be an interaction from the user first. (Such as button click, keydown/keypress etc.)

But its not tested with 2 million record, it will do but consume memory on machine as you have to load 2 million record and insert it.
I'd suggest a RelativeLayout instead of a FrameLayout.
Assuming that you want to have the TextView always below the ImageView I'd use following layout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageView
android:id="@+id/imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerInParent="true"
android:src="@drawable/icon"
android:visibility="visible"/>
<TextView
android:id="@+id/textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_below="@id/imageview"
android:gravity="center"
android:text="@string/hello"/>
</RelativeLayout>
Note that if you set the visibility
of an element to gone
then the space that element would consume is gone whereas when you use invisible
instead the space it'd consume will be preserved.
If you want to have the TextView on top of the ImageView then simply leave out the android:layout_alignParentTop
or set it to false
and on the TextView leave out the android:layout_below="@id/imageview"
attribute. Like this.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageView
android:id="@+id/imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="false"
android:layout_centerInParent="true"
android:src="@drawable/icon"
android:visibility="visible"/>
<TextView
android:id="@+id/textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:gravity="center"

I hope this is what you were looking for.
assertTrue()/assertFalse() : to use only to assert boolean result returned
assertTrue(Iterables.elementsEqual(argumentComponents, returnedComponents));
You want to use Assert.assertTrue()
or Assert.assertFalse()
as the method under test returns a boolean
value.
As the method returns a specific thing such as a List
that should contain some expected elements, asserting with assertTrue()
in this way : Assert.assertTrue(myActualList.containsAll(myExpectedList)
is an anti pattern.
It makes the assertion easy to write but as the test fails, it also makes it hard to debug because the test runner will only say to you something like :
expected
true
but actual isfalse
Assert.assertEquals(Object, Object)
in JUnit4 or Assertions.assertIterableEquals(Iterable, Iterable)
in JUnit 5 : to use only as both equals()
and toString()
are overrided for the classes (and deeply) of the compared objects
It matters because the equality test in the assertion relies on equals()
and the test failure message relies on toString()
of the compared objects.
As String
overrides both equals()
and toString()
, it is perfectly valid to assert the List<String>
with assertEquals(Object,Object)
.
And about this matter : you have to override equals()
in a class because it makes sense in terms of object equality, not only to make assertions easier in a test with JUnit.
To make assertions easier you have other ways (that you can see in the next points of the answer).
Is Guava a way to perform/build unit test assertions ?
Is Google Guava Iterables.elementsEqual() the best way, provided I have the library in my build path, to compare those two lists?
No it is not. Guava is not an library to write unit test assertions.
You don't need it to write most (all I think) of unit tests.
What's the canonical way to compare lists for unit tests?
As a good practice I favor assertion/matcher libraries.
I cannot encourage JUnit to perform specific assertions because this provides really too few and limited features : it performs only an assertion with a deep equals.
Sometimes you want to allow any order in the elements, sometimes you want to allow that any elements of the expected match with the actual, and so for...
So using a unit test assertion/matcher library such as Hamcrest or AssertJ is the correct way.
The actual answer provides a Hamcrest solution. Here is a AssertJ solution.
org.assertj.core.api.ListAssert.containsExactly()
is what you need : it verifies that the actual group contains exactly the given values and nothing else, in order as stated :
Verifies that the actual group contains exactly the given values and nothing else, in order.
Your test could look like :
import org.assertj.core.api.Assertions;
import org.junit.jupiter.api.Test;
@Test
void ofComponent_AssertJ() throws Exception {
MyObject myObject = MyObject.ofComponents("One", "Two", "Three");
Assertions.assertThat(myObject.getComponents())
.containsExactly("One", "Two", "Three");
}
A AssertJ good point is that declaring a List
as expected is needless : it makes the assertion straighter and the code more readable :
Assertions.assertThat(myObject.getComponents())
.containsExactly("One", "Two", "Three");
And if the test fails :
// Fail : Three was not expected
Assertions.assertThat(myObject.getComponents())
.containsExactly("One", "Two");
you get a very clear message such as :
java.lang.AssertionError:
Expecting:
<["One", "Two", "Three"]>
to contain exactly (and in same order):
<["One", "Two"]>
but some elements were not expected:
<["Three"]>
Assertion/matcher libraries are a must because these will really further
Suppose that MyObject
doesn't store String
s but Foo
s instances such as :
public class MyFooObject {
private List<Foo> values;
@SafeVarargs
public static MyFooObject ofComponents(Foo... values) {
// ...
}
public List<Foo> getComponents(){
return new ArrayList<>(values);
}
}
That is a very common need.
With AssertJ the assertion is still simple to write. Better you can assert that the list content are equal even if the class of the elements doesn't override equals()/hashCode()
while JUnit ways require that :
import org.assertj.core.api.Assertions;
import static org.assertj.core.groups.Tuple.tuple;
import org.junit.jupiter.api.Test;
@Test
void ofComponent() throws Exception {
MyFooObject myObject = MyFooObject.ofComponents(new Foo(1, "One"), new Foo(2, "Two"), new Foo(3, "Three"));
Assertions.assertThat(myObject.getComponents())
.extracting(Foo::getId, Foo::getName)
.containsExactly(tuple(1, "One"),
tuple(2, "Two"),
tuple(3, "Three"));
}
EDIT : my bad! With my answer, the icon won't behave as a toggler Actually, it will be shown even when not collapsed... Still searching...
This would work :
<button class="btn btn-primary" type="button" data-toggle="collapse"
data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent"
aria-expanded="false" aria-label="Toggle navigation">
<span>
<i class="fas fa-bars"></i>
</span>
</button>
The trick proposed by my answer is to replace the navbar-toggler
with a classical button class btn
and then, as answered earlier, use an icon font.
Note, that if you keep <button class="navbar-toggler">
, the button will have a "strange" shape.
As stated in this post on github, bootstrap uses some "css trickery", so users don't have to rely on fonts.
So, just don't use the "navbar-toggler"
class on your button if you want to use an icon font.
Cheers.
Just repair Visual Studio itself from the control panel and that should do the trick!
While your Sleep
method is async, Thread.Sleep
is not. The whole idea of async is to reuse a single thread, not to start multiple threads. Because you've blocked using a synchronous call to Thread.Sleep, it's not going to work.
I'm assuming that Thread.Sleep
is a simplification of what you actually want to do. Can your actual implementation be coded as async methods?
If you do need to run multiple synchronous blocking calls, look elsewhere I think!
I've written an extension class to help me deserializing from JSON sources (string, stream, file).
public static class JsonHelpers
{
public static T CreateFromJsonStream<T>(this Stream stream)
{
JsonSerializer serializer = new JsonSerializer();
T data;
using (StreamReader streamReader = new StreamReader(stream))
{
data = (T)serializer.Deserialize(streamReader, typeof(T));
}
return data;
}
public static T CreateFromJsonString<T>(this String json)
{
T data;
using (MemoryStream stream = new MemoryStream(System.Text.Encoding.Default.GetBytes(json)))
{
data = CreateFromJsonStream<T>(stream);
}
return data;
}
public static T CreateFromJsonFile<T>(this String fileName)
{
T data;
using (FileStream fileStream = new FileStream(fileName, FileMode.Open))
{
data = CreateFromJsonStream<T>(fileStream);
}
return data;
}
}
Deserializing is now as easy as writing:
MyType obj1 = aStream.CreateFromJsonStream<MyType>();
MyType obj2 = "{\"key\":\"value\"}".CreateFromJsonString<MyType>();
MyType obj3 = "data.json".CreateFromJsonFile<MyType>();
Hope it will help someone else.
In my case that happened when uninstalling AspNet 5 RC1 Update 1 to update it for .Net Core 1.0 RC2. so I installed Visual Studio 2015 update 2, selected Microsoft Web Developer tools and everything went back to normal.
EOF indicates "end of file". A newline (which is what happens when you press enter) isn't the end of a file, it's the end of a line, so a newline doesn't terminate this loop.
The code isn't wrong[*], it just doesn't do what you seem to expect. It reads to the end of the input, but you seem to want to read only to the end of a line.
The value of EOF is -1 because it has to be different from any return value from getchar
that is an actual character. So getchar
returns any character value as an unsigned char, converted to int, which will therefore be non-negative.
If you're typing at the terminal and you want to provoke an end-of-file, use CTRL-D (unix-style systems) or CTRL-Z (Windows). Then after all the input has been read, getchar()
will return EOF
, and hence getchar() != EOF
will be false, and the loop will terminate.
[*] well, it has undefined behavior if the input is more than LONG_MAX characters due to integer overflow, but we can probably forgive that in a simple example.
Ross, you can use Arrays.copyof() or Arrays.copyOfRange() too.
Integer[] integerArray = Arrays.copyOf(a, a.length, Integer[].class);
Integer[] integerArray = Arrays.copyOfRange(a, 0, a.length, Integer[].class);
Here the reason to hitting an ClassCastException
is you can't treat an array of Integer
as an array of Object
. Integer[]
is a subtype of Object[]
but Object[]
is not a Integer[]
.
And the following also will not give an ClassCastException
.
Object[] a = new Integer[1];
Integer b=1;
a[0]=b;
Integer[] c = (Integer[]) a;
In my project with netcore 2.2 I use this code:
[HttpGet]
[Route( "something" )]
public IActionResult GetSomething()
{
string payload = "Something";
OkObjectResult result = Ok( payload );
// currently result.Formatters is empty but we'd like to ensure it will be so in the future
result.Formatters.Clear();
// force response as xml
result.Formatters.Add( new Microsoft.AspNetCore.Mvc.Formatters.XmlSerializerOutputFormatter() );
return result;
}
It forces only one action within a controller to return a xml without effect to other actions. Also this code doesn't contain neither HttpResponseMessage or StringContent or ObjectContent which are disposable objects and hence should be handled appropriately (it is especially a problem if you use any of code analyzers that reminds you about it).
Going further you could use a handy extension like this:
public static class ObjectResultExtensions
{
public static T ForceResultAsXml<T>( this T result )
where T : ObjectResult
{
result.Formatters.Clear();
result.Formatters.Add( new Microsoft.AspNetCore.Mvc.Formatters.XmlSerializerOutputFormatter() );
return result;
}
}
And your code will become like this:
[HttpGet]
[Route( "something" )]
public IActionResult GetSomething()
{
string payload = "Something";
return Ok( payload ).ForceResultAsXml();
}
In addition, this solution looks like an explicit and clean way to force return as xml and it is easy to add to your existent code.
P.S. I used fully-qualified name Microsoft.AspNetCore.Mvc.Formatters.XmlSerializerOutputFormatter just to avoid ambiguity.
Take a look at the keypress
function.
I believe the enter
key is 13
so you would want something like:
$('#searchButton').keypress(function(e){
if(e.which == 13){ //Enter is key 13
//Do something
}
});
Check the answer from Marc from C#: Good/best implementation of Swap method.
public static void Swap<T>(IList<T> list, int indexA, int indexB)
{
T tmp = list[indexA];
list[indexA] = list[indexB];
list[indexB] = tmp;
}
which can be linq-i-fied like
public static IList<T> Swap<T>(this IList<T> list, int indexA, int indexB)
{
T tmp = list[indexA];
list[indexA] = list[indexB];
list[indexB] = tmp;
return list;
}
var lst = new List<int>() { 8, 3, 2, 4 };
lst = lst.Swap(1, 2);
We can concat Like this :
<h5 th:text ="${currentItem.first_name}+ ' ' + ${currentItem.last_name}"></h5>
Make sure you have the URL correct for whatever you are downloading. First of all, URLs with characters like ?
and such cannot be parsed and resolved. This will confuse the cmd line and accept any characters that aren't resolved into the source URL name as the file name you are downloading into.
For example:
wget "sourceforge.net/projects/ebosse/files/latest/download?source=typ_redirect"
will download into a file named, ?source=typ_redirect
.
As you can see, knowing a thing or two about URLs helps to understand wget
.
I am booting from a hirens disk and only had Linux 2.6.1 as a resource (import os is unavailable). The correct syntax that solved my problem downloading an ISO onto the physical hard drive was:
wget "(source url)" -O (directory where HD was mounted)/isofile.iso"
One could figure the correct URL by finding at what point wget
downloads into a file named index.html
(the default file), and has the correct size/other attributes of the file you need shown by the following command:
wget "(source url)"
Once that URL and source file is correct and it is downloading into index.html
, you can stop the download (ctrl + z) and change the output file by using:
-O "<specified download directory>/filename.extension"
after the source url.
In my case this results in downloading an ISO and storing it as a binary file under isofile.iso
, which hopefully mounts.
all you need is to tie the group to a different item in your model
@Html.RadioButtonFor(x => x.Field1, "Milk")
@Html.RadioButtonFor(x => x.Field1, "Butter")
@Html.RadioButtonFor(x => x.Field2, "Water")
@Html.RadioButtonFor(x => x.Field2, "Beer")
You can do that with some easy jQuery:
var elementPosition = $('#navigation').offset();
$(window).scroll(function(){
if($(window).scrollTop() > elementPosition.top){
$('#navigation').css('position','fixed').css('top','0');
} else {
$('#navigation').css('position','static');
}
});
Your JFrame default close action can be set to "DISPOSE_ON_CLOSE
" instead of EXIT_ON_CLOSE
(why people keep using EXIT_ON_CLOSE is beyond me).
If you have any undisposed windows or non-daemon threads, your application will not terminate. This should be considered a error (and solving it with System.exit is a very bad idea).
The most common culprits are java.util.Timer and a custom Thread you've created. Both should be set to daemon or must be explicitly killed.
If you want to check for all active frames, you can use Frame.getFrames()
. If all Windows/Frames are disposed of, then use a debugger to check for any non-daemon threads that are still running.
Use this to detach user variables from global to check variable at the moment.
function get_user_var_defined ()
{
return array_slice($GLOBALS,8,count($GLOBALS)-8);
}
function get_var_name ($var)
{
$vuser = get_user_var_defined();
foreach($vuser as $key=>$value)
{
if($var===$value) return $key ;
}
}
You can use IDR it is a great program to decompile Delphi, it is updated to the current Delphi versions and it has a lot of features.
This worked for me on my Oracle database:
SELECT 'GRANT SELECT, insert, update, delete ON mySchema.' || TABLE_NAME || ' to myUser;'
FROM user_tables
where table_name like 'myTblPrefix%'
Then, copy the results, paste them into your editor, then run them like a script.
You could also write a script and use "Execute Immediate" to run the generated SQL if you don't want the extra copy/paste steps.
function phpconsole($label='var', $x) {
?>
<script type="text/javascript">
console.log('<?php echo ($label)?>');
console.log('<?php echo json_encode($x)?>');
</script>
<?php
}
Use the keyword super within the overridden method in the child class to use the parent class method. You can only use the keyword within the overridden method though. The example below will help.
public class Parent {
public int add(int m, int n){
return m+n;
}
}
public class Child extends Parent{
public int add(int m,int n,int o){
return super.add(super.add(m, n),0);
}
}
public class SimpleInheritanceTest {
public static void main(String[] a){
Child child = new Child();
child.add(10, 11);
}
}
The add
method in the Child class calls super.add
to reuse the addition logic.
Yes subprocess.Popen(cmd, ..., shell=True)
works like a charm. On Windows the .py
file extension is recognized, so Python is invoked to process it (on *NIX just the usual shebang). The path environment controls whether things are seen. So the first arg to Popen
is just the name of the script.
subprocess.Popen(['myscript.py', 'arg1', ...], ..., shell=True)
You can override the default css rules with this:
.table tbody tr > td.success {
background-color: #dff0d8 !important;
}
.table tbody tr > td.error {
background-color: #f2dede !important;
}
.table tbody tr > td.warning {
background-color: #fcf8e3 !important;
}
.table tbody tr > td.info {
background-color: #d9edf7 !important;
}
.table-hover tbody tr:hover > td.success {
background-color: #d0e9c6 !important;
}
.table-hover tbody tr:hover > td.error {
background-color: #ebcccc !important;
}
.table-hover tbody tr:hover > td.warning {
background-color: #faf2cc !important;
}
.table-hover tbody tr:hover > td.info {
background-color: #c4e3f3 !important;
}
!important
is needed as bootstrap actually colours the cells individually (afaik it's not possible to just apply background-color to a tr). I couldn't find any colour variables in my version of bootstrap but that's the basic idea anyway.

I found this to drop all tables in a database:
mysqldump -uUSERNAME -pPASSWORD --add-drop-table --no-data DATABASENAME | grep ^DROP | mysql -uUSERNAME -pPASSWORD DATABASENAME
Usefull if you are limited by hosting solution (not able to drop a whole database).
I modified it to truncate the tables. There is no "--add-truncate-table" for mysqldump, so i did:
mysqldump -uUSERNAME -pPASSWORD --add-drop-table --no-data DATABASENAME | grep ^DROP | sed -e 's/DROP TABLE IF EXISTS/TRUNCATE TABLE/g' | mysql -uUSERNAME -pPASSWORD DATABASENAME
works for me --edit, fixing a typo in the last command

I love how easy this is in Android Studio.
In Android Studio go to File > Settings > Version Control > GitHub. Then enter your GitHub username and password. (You only have to do this step once. For future projects you can skip it.)
With your Android Studio project open, go to VCS > Import into Version Control > Share Project on GitHub.
Then click Share and OK.
That's all!
Best way to fix some unnecessary changes is to invalidate caches
Go to FILE -> click "INVALIDATE CACHES/RESTART" then a dialog box will pop-up, Select "INVALIDATE CACHES/RESTART" button.
Android studio will automatically restart and rebuild the index.
Try this:
// convert string to stream
byte[] byteArray = Encoding.UTF8.GetBytes(contents);
//byte[] byteArray = Encoding.ASCII.GetBytes(contents);
MemoryStream stream = new MemoryStream(byteArray);
and
// convert stream to string
StreamReader reader = new StreamReader(stream);
string text = reader.ReadToEnd();
Maybe your file contains CRLF terminator. Every lines followed by \r\n.
awk
recognizes the $2
actually $2\r
. The \r
means goto the start of the line.
{print $2\r$1}
will print $2
first, then return to the head, then print $1
. So the field 2 is overlaid by the field 1.
The standard techniques to filter a list apply, although they are not as efficient as the split/join
or translate
methods.
We need a set of whitespaces:
>>> import string
>>> ws = set(string.whitespace)
The filter
builtin:
>>> "".join(filter(lambda c: c not in ws, "strip my spaces"))
'stripmyspaces'
A list comprehension (yes, use the brackets: see benchmark below):
>>> import string
>>> "".join([c for c in "strip my spaces" if c not in ws])
'stripmyspaces'
A fold:
>>> import functools
>>> "".join(functools.reduce(lambda acc, c: acc if c in ws else acc+c, "strip my spaces"))
'stripmyspaces'
Benchmark:
>>> from timeit import timeit
>>> timeit('"".join("strip my spaces".split())')
0.17734256500003198
>>> timeit('"strip my spaces".translate(ws_dict)', 'import string; ws_dict = {ord(ws):None for ws in string.whitespace}')
0.457635745999994

Most of answers talking about scenario catch-log-rethrow.
Instead of writing it in your code consider to use AOP, in particular Postsharp.Diagnostic.Toolkit with OnExceptionOptions IncludeParameterValue and IncludeThisArgument
I wanted a solution to copy files modified after a certain date and time which mean't I need to use Get-ChildItem piped through a filter. Below is what I came up with:
$SourceFolder = "C:\Users\RCoode\Documents\Visual Studio 2010\Projects\MyProject"
$ArchiveFolder = "J:\Temp\Robin\Deploy\MyProject"
$ChangesStarted = New-Object System.DateTime(2013,10,16,11,0,0)
$IncludeFiles = ("*.vb","*.cs","*.aspx","*.js","*.css")
Get-ChildItem $SourceFolder -Recurse -Include $IncludeFiles | Where-Object {$_.LastWriteTime -gt $ChangesStarted} | ForEach-Object {
$PathArray = $_.FullName.Replace($SourceFolder,"").ToString().Split('\')
$Folder = $ArchiveFolder
for ($i=1; $i -lt $PathArray.length-1; $i++) {
$Folder += "\" + $PathArray[$i]
if (!(Test-Path $Folder)) {
New-Item -ItemType directory -Path $Folder
}
}
$NewPath = Join-Path $ArchiveFolder $_.FullName.Replace($SourceFolder,"")
Copy-Item $_.FullName -Destination $NewPath
}
I would advise against using """
for multi line comments!
Here is a simple example to highlight what might be considered an unexpected behavior:
print('{}\n{}'.format(
'I am a string',
"""
Some people consider me a
multi-line comment, but
"""
'clearly I am also a string'
)
)
Now have a look at the output:
I am a string
Some people consider me a
multi-line comment, but
clearly I am also a string
The multi line string was not treated as comment, but it was concatenated with 'clearly I'm also a string'
to form a single string.
If you want to comment multiple lines do so according to PEP 8 guidelines:
print('{}\n{}'.format(
'I am a string',
# Some people consider me a
# multi-line comment, but
'clearly I am also a string'
)
)
Output:
I am a string
clearly I am also a string
It's not that much work to make a function that's allocating the needed memory for your string. That's a little c-function i wrote some time ago, i always use it to read in strings.
It will return the read string or if a memory error occurs NULL. But be aware that you have to free() your string and always check for it's return value.
#define BUFFER 32
char *readString()
{
char *str = malloc(sizeof(char) * BUFFER), *err;
int pos;
for(pos = 0; str != NULL && (str[pos] = getchar()) != '\n'; pos++)
{
if(pos % BUFFER == BUFFER - 1)
{
if((err = realloc(str, sizeof(char) * (BUFFER + pos + 1))) == NULL)
free(str);
str = err;
}
}
if(str != NULL)
str[pos] = '\0';
return str;
}
Some basic differences can be written in short:
MVC:
Traditional MVC is where there is a
MVP:
Similar to traditional MVC but Controller is replaced by Presenter. But the Presenter, unlike Controller is responsible for changing the view as well. The view usually does not call the presenter.
MVVM
The difference here is the presence of View Model. It is kind of an implementation of Observer Design Pattern, where changes in the model are represented in the view as well, by the VM. Eg: If a slider is changed, not only the model is updated but the data which may be a text, that is displayed in the view is updated as well. So there is a two-way data binding.
You could also use zip
import matplotlib.pyplot as plt
l = [(0, 6.0705199999997801e-08), (1, 2.1015700100300739e-08),
(2, 7.6280656623374823e-09), (3, 5.7348209304555086e-09),
(4, 3.6812203579604238e-09), (5, 4.1572516753310418e-09)]
x, y = zip(*l)
plt.plot(x, y)
The easiest thing is if you can make the WPF bitmap from a file directly.
Otherwise you will have to use System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap.
i got the same problem after clicking update plugins, i tried all the suggestions above and failed , the only thing that worked for my is reinstalling android studio..
Yaur: Although what you have copied and pasted is good advice, this does not mean that it is impossible to change the source element of an HTML5 video element elegantly, even in IE9 (or IE8 for that matter).(This solution does NOT involve replacing the entire video element, as it is bad coding practice).
A complete solution to changing/switching videos in HTML5 video tags via javascript can be found here and is tested in all HTML5 browser (Firefox, Chrome, Safari, IE9, etc).
If this helps, or if you're having trouble, please let me know.
As others already said, there seems to be no good solution to do that easily.
But to keep your code clean I suggest creating a seperate class that hides the ugly XAML.

Tip: You can add an UserControl with name "ButtonEx" to your project in VS Studio and then copy paste the stuff above in.
Generally building with the NDK is as simple as correctly specifying an ndkBuild path to Android.mk or cmake path to CMakeLists.txt. I recommend CMake over the older Android.mk because Android Studio's C/C++ support is based upon CLion and it uses CMake as its project format. This in my experience has tended to make the IDE more responsive on larger projects. Everything compiled in your project will be built and copied into the APK automatically.
apply plugin: 'com.android.library'
android {
compileSdkVersion 19
buildToolsVersion "25.0.2"
defaultConfig {
minSdkVersion 19
targetSdkVersion 19
ndk {
abiFilters 'armeabi', 'armeabi-v7a', 'x86'
// 64-bit support requires an Android API level higher than 19; Namely 21 and higher
//abiFilters 'armeabi', 'armeabi-v7a', 'arm64-v8a', 'x86', 'x86_64'
}
externalNativeBuild {
cmake {
arguments '-DANDROID_TOOLCHAIN=clang',
'-DANDROID_PLATFORM=android-19',
'-DANDROID_STL=gnustl_static',
'-DANDROID_ARM_NEON=TRUE'
}
}
}
externalNativeBuild {
cmake {
path 'src/main/jni/CMakeLists.txt'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
}
Static libraries (.a) in your NDK build will automatically be included, but prebuilt dynamic libraries (.so) will need to be placed in jniLibs
. This can be configured using sourceSets
, but you should adopt the standard. You DO NOT NEED any additional commands in build.gradle
when including prebuilt libraries.
jniLibs
You can find more information about the structure in the Android Gradle Plugin User Guide.
|--app: |--|--build.gradle |--|--src: |--|--|--main |--|--|--|--java |--|--|--|--jni |--|--|--|--|--CMakeLists.txt |--|--|--|--jniLibs |--|--|--|--|--armeabi |--|--|--|--|--|--.so Files |--|--|--|--|--armeabi-v7a |--|--|--|--|--|--.so Files |--|--|--|--|--x86 |--|--|--|--|--|--.so Files
You can then validate the resulting APK contains your .so files, typically under build/outputs/apk/
, using unzip -l myApp.apk
to list the contents.
If you're building a shared library in the NDK you do not need to do anything further. It will be correctly bundled in the APK.
I encountered this as well and the solution is simple, dont hardcode the array index position in your code.
Instead of
$data[0]['somekey']
do
foreach($data as $data_item)
{
echo $data_item['somekey'];
}
If there is an array or more you can perform your desired action inside the loop, but if it's undefined it will not bring an error. you can also add other checks on top of that.
You could also add a variable and increment it in a for in loop to limit your looping if you want only the first positions or something.
