Similarly to other languages, the fastest "modulo 2" (odd/even) operation is done using the bitwise and
operator:
if x & 1:
return 'odd'
else:
return 'even'
&
(bitwise AND) of the Number by 1 will be 1, because the last bit would already be set. Otherwise it will give 0 as output.import java.io.*;
class Initials {
public static void main(String args[]) throws IOException {
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String s;
char x;
int l;
System.out.print("Enter any sentence: ");
s = br.readLine();
s = " " + s; //adding a space infront of the inputted sentence or a name
s = s.toUpperCase(); //converting the sentence into Upper Case (Capital Letters)
l = s.length(); //finding the length of the sentence
System.out.print("Output = ");
for (int i = 0; i < l; i++) {
x = s.charAt(i); //taking out one character at a time from the sentence
if (x == ' ') //if the character is a space, printing the next Character along with a fullstop
System.out.print(s.charAt(i + 1) + ".");
}
}
}
You should not be repeating the string
part when sending parameters.
int wordLength = wordLengthFunction(word); //you do not put string word here.
I have a project that does this whenever I build with the View open. As soon as I closed the view, the error goes away and the build succeeds. Very strange.
Most of the answers provided here address the number of incoming requests to your backend webservice, not the number of outgoing requests you can make from your ASP.net application to your backend service.
It's not your backend webservice that is throttling your request rate here, it is the number of open connections your calling application is willing to establish to the same endpoint (same URL).
You can remove this limitation by adding the following configuration section to your machine.config file:
<configuration>
<system.net>
<connectionManagement>
<add address="*" maxconnection="65535"/>
</connectionManagement>
</system.net>
</configuration>
You could of course pick a more reasonable number if you'd like such as 50 or 100 concurrent connections. But the above will open it right up to max. You can also specify a specific address for the open limit rule above rather than the '*' which indicates all addresses.
MSDN Documentation for System.Net.connectionManagement
Another Great Resource for understanding ConnectManagement in .NET
Hope this solves your problem!
EDIT: Oops, I do see you have the connection management mentioned in your code above. I will leave my above info as it is relevant for future enquirers with the same problem. However, please note there are currently 4 different machine.config files on most up to date servers!
There is .NET Framework v2 running under both 32-bit and 64-bit as well as .NET Framework v4 also running under both 32-bit and 64-bit. Depending on your chosen settings for your application pool you could be using any one of these 4 different machine.config files! Please check all 4 machine.config files typically located here:
Oh ok - now I get it. You can ignore this one - the XML for this is just not correct - the packages-element is indeed not declared (there is no reference to a schema or whatever). I think this is a known minor bug that won't do a thing because only NuGet will use this.
See this similar question also.
To make the transform work in development (using F5 or CTRL + F5) I drop ctt.exe (https://ctt.codeplex.com/) in the packages folder (packages\ConfigTransform\ctt.exe).
Then I register a pre- or post-build event in Visual Studio...
$(SolutionDir)packages\ConfigTransform\ctt.exe source:"$(ProjectDir)connectionStrings.config" transform:"$(ProjectDir)connectionStrings.$(ConfigurationName).config" destination:"$(ProjectDir)connectionStrings.config"
$(SolutionDir)packages\ConfigTransform\ctt.exe source:"$(ProjectDir)web.config" transform:"$(ProjectDir)web.$(ConfigurationName).config" destination:"$(ProjectDir)web.config"
For the transforms I use SlowCheeta VS extension (https://visualstudiogallery.msdn.microsoft.com/69023d00-a4f9-4a34-a6cd-7e854ba318b5).
If you use Java8 or above, you can use with stream() with native.
publicArray.stream()
.map(Object::toString)
.collect(Collectors.joining(" "));
I use Windows Explorer, navigate to C:\Windows\assembly , find the one I need. From the Properties you can copy the PublicKeyToken.
This doesn't rely on Visual Studio or any other utilities being installed.
Have a look at fabric.transfer.

Glide V4:
Glide.with(context)
.load(url)
.circleCrop()
.into(imageView);
Glide V3:
You can use RoundedBitmapDrawable
for circular images with Glide. No custom ImageView is required.
Glide.with(context).load(url).asBitmap().centerCrop().into(new BitmapImageViewTarget(imageView) {
@Override
protected void setResource(Bitmap resource) {
RoundedBitmapDrawable circularBitmapDrawable =
RoundedBitmapDrawableFactory.create(context.getResources(), resource);
circularBitmapDrawable.setCircular(true);
imageView.setImageDrawable(circularBitmapDrawable);
}
});
First off, BigDecimal.multiply()
returns a BigDecimal
and you're trying to store that in an int
.
Second, it takes another BigDecimal
as the argument, not an int
.
If you just use the BigDecimal
for all variables involved in these calculations, it should work fine.

In case that might help, I found a workaround for a similar problem, looking at the cmake doc : https://cmake.org/cmake/help/v3.0/module/FindPythonLibs.html
You must set two env vars for cmake to find coherent versions. Unfortunately this is not a generic solution...
cmake -DPYTHON_LIBRARY=${HOME}/.pyenv/versions/3.8.0/lib/libpython3.8.a -DPYTHON_INCLUDE_DIR=${HOME}/.pyenv/versions/3.8.0/include/python3.8/ cern_root/
Requirements:
Django==2.0.2
, django-querysetsequence==0.8
In case you want to combine querysets
and still come out with a QuerySet
, you might want to check out django-queryset-sequence.
But one note about it. It only takes two querysets
as it's argument. But with python reduce
you can always apply it to multiple queryset
s.
from functools import reduce
from queryset_sequence import QuerySetSequence
combined_queryset = reduce(QuerySetSequence, list_of_queryset)
And that's it. Below is a situation I ran into and how I employed list comprehension
, reduce
and django-queryset-sequence
from functools import reduce
from django.shortcuts import render
from queryset_sequence import QuerySetSequence
class People(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
mentor = models.ForeignKey('self', null=True, on_delete=models.SET_NULL, related_name='my_mentees')
class Book(models.Model):
name = models.CharField(max_length=20)
owner = models.ForeignKey(Student, on_delete=models.CASCADE)
# as a mentor, I want to see all the books owned by all my mentees in one view.
def mentee_books(request):
template = "my_mentee_books.html"
mentor = People.objects.get(user=request.user)
my_mentees = mentor.my_mentees.all() # returns QuerySet of all my mentees
mentee_books = reduce(QuerySetSequence, [each.book_set.all() for each in my_mentees])
return render(request, template, {'mentee_books' : mentee_books})
This won't be possible with css - an image is a square, and so the shadow would be the shadow of a square. The easiest way would be to use photoshop/gimp or any other image editor to apply the shadow like core draw.
I have the same kind of problem. the error was not in the Dialog
but in a EditText
. I was trying to change the value of the Edittext
inside of a Assynctask
. the only away i could solve was creating a new runnable
.
runOnUiThread(new Runnable(){
@Override
public void run() {
...
}
});
The theoretical limit is O(n) because you need to touch each sock (unless some are already paired somehow).
You can achieve O(n) with radix sort. You just need to pick some attributes for the buckets.
If you can pick a limited number of attributes, but enough attributes that can uniquely identify each pair, you should be done in O(k * n), which is O(n) if we can consider k is limited.
For multiple interval types use a nested construction as in:
UPDATE table SET date = DATE_ADD(DATE_ADD(date, INTERVAL 1 YEAR), INTERVAL 1 DAY)
For updating a given date in the column date
to 1 year + 1 day
From the MSDN library:
The
First<TSource>(IEnumerable<TSource>)
method throws an exception if source contains no elements. To instead return a default value when the source sequence is empty, use theFirstOrDefault
method.
To delete a cookie I set it again with an empty value and expiring in 1 second. In details, I always use one of the following flavours (I tend to prefer the second one):
1.
function setCookie(key, value, expireDays, expireHours, expireMinutes, expireSeconds) {
var expireDate = new Date();
if (expireDays) {
expireDate.setDate(expireDate.getDate() + expireDays);
}
if (expireHours) {
expireDate.setHours(expireDate.getHours() + expireHours);
}
if (expireMinutes) {
expireDate.setMinutes(expireDate.getMinutes() + expireMinutes);
}
if (expireSeconds) {
expireDate.setSeconds(expireDate.getSeconds() + expireSeconds);
}
document.cookie = key +"="+ escape(value) +
";domain="+ window.location.hostname +
";path=/"+
";expires="+expireDate.toUTCString();
}
function deleteCookie(name) {
setCookie(name, "", null , null , null, 1);
}
Usage:
setCookie("reminder", "buyCoffee", null, null, 20);
deleteCookie("reminder");
2
function setCookie(params) {
var name = params.name,
value = params.value,
expireDays = params.days,
expireHours = params.hours,
expireMinutes = params.minutes,
expireSeconds = params.seconds;
var expireDate = new Date();
if (expireDays) {
expireDate.setDate(expireDate.getDate() + expireDays);
}
if (expireHours) {
expireDate.setHours(expireDate.getHours() + expireHours);
}
if (expireMinutes) {
expireDate.setMinutes(expireDate.getMinutes() + expireMinutes);
}
if (expireSeconds) {
expireDate.setSeconds(expireDate.getSeconds() + expireSeconds);
}
document.cookie = name +"="+ escape(value) +
";domain="+ window.location.hostname +
";path=/"+
";expires="+expireDate.toUTCString();
}
function deleteCookie(name) {
setCookie({name: name, value: "", seconds: 1});
}
Usage:
setCookie({name: "reminder", value: "buyCoffee", minutes: 20});
deleteCookie("reminder");
The best way I found was to check the difference between the given date and today:
NSCalendar* calendar = [NSCalendar currentCalendar];
NSDate* now = [NSDate date];
int differenceInDays =
[calendar ordinalityOfUnit:NSCalendarUnitDay inUnit:NSCalendarUnitEra forDate:date] -
[calendar ordinalityOfUnit:NSCalendarUnitDay inUnit:NSCalendarUnitEra forDate:now];
According to Listing 13 of Calendrical Calculations in Apple's Date and Time Programming Guide [NSCalendar ordinalityOfUnit:NSDayCalendarUnit inUnit: NSEraCalendarUnit forDate:myDate] gives you the number of midnights since the start of the era. This way it's easy to check whether the date is yesterday, today, or tomorrow.
switch (differenceInDays) {
case -1:
dayString = @"Yesterday";
break;
case 0:
dayString = @"Today";
break;
case 1:
dayString = @"Tomorrow";
break;
default: {
NSDateFormatter* dayFormatter = [[NSDateFormatter alloc] init];
[dayFormatter setLocale:usLocale];
[dayFormatter setDateFormat:@"dd MMM"];
dayString = [dayFormatter stringFromDate: date];
break;
}
}
As an alternative to Pingdom I suggest trying Uptimerobot. It is free and offers 5 min interval site checking. It works very fine for me.
UPDATE 7th of May 2015: This will not be possible any more, as Heroku will change their free dyno to prevent keeping it alive for full 24 hours:
Another important change has to do with dyno sleeping, or ‘idling’. While non-paid apps have always slept after an activity timeout, some apps used automatic pinging services to prevent that behavior. free dynos are allowed 18 hours awake per 24 hour period, and over the next few weeks we will begin to notify users of apps that exceed that limit. With the introduction of the hobby dyno ($7 per month), we are asking to either let your app sleep after time out, or upgrade to this new option.
When is this going to be live? According to their blog post:
Applications running a single 1X dyno that don’t accumulate any other dyno charges will be migrated gradually to the new free dynos beginning on July 1.
You should use the grep
-q
flag for quiet output. See the man pages below:
man grep output :
General Output Control
-q, --quiet, --silent
Quiet; do not write anything to standard output. Exit immediately with zero status
if any match is found, even if an error was detected. Also see the -s or
--no-messages option. (-q is specified by POSIX.)
This KornShell (ksh) script demos the grep
quiet output and is a solution to your question.

I've created an ActionButton method for the HtmlHelper. It will generate normal input button with a bit of javascript in the OnClick event that will submit the form to the specified Controller/Action.
You use the helper like that
@Html.ActionButton("MyControllerName", "MyActionName", "button text")
this will generate the following HTML
<input type="button" value="button text" onclick="this.form.action = '/MyWebsiteFolder/MyControllerName/MyActionName'; this.form.submit();">
Here is the extension method code:
VB.Net
<System.Runtime.CompilerServices.Extension()>
Function ActionButton(pHtml As HtmlHelper, pAction As String, pController As String, pRouteValues As Object, pBtnValue As String, pBtnName As String, pBtnID As String) As MvcHtmlString
Dim urlHelperForActionLink As UrlHelper
Dim btnTagBuilder As TagBuilder
Dim actionLink As String
Dim onClickEventJavascript As String
urlHelperForActionLink = New UrlHelper(pHtml.ViewContext.RequestContext)
If pController <> "" Then
actionLink = urlHelperForActionLink.Action(pAction, pController, pRouteValues)
Else
actionLink = urlHelperForActionLink.Action(pAction, pRouteValues)
End If
onClickEventJavascript = "this.form.action = '" & actionLink & "'; this.form.submit();"
btnTagBuilder = New TagBuilder("input")
btnTagBuilder.MergeAttribute("type", "button")
btnTagBuilder.MergeAttribute("onClick", onClickEventJavascript)
If pBtnValue <> "" Then btnTagBuilder.MergeAttribute("value", pBtnValue)
If pBtnName <> "" Then btnTagBuilder.MergeAttribute("name", pBtnName)
If pBtnID <> "" Then btnTagBuilder.MergeAttribute("id", pBtnID)
Return MvcHtmlString.Create(btnTagBuilder.ToString(TagRenderMode.Normal))
End Function
C# (the C# code is just decompiled from the VB DLL, so it can get some beautification... but time is so short :-))
public static MvcHtmlString ActionButton(this HtmlHelper pHtml, string pAction, string pController, object pRouteValues, string pBtnValue, string pBtnName, string pBtnID)
{
UrlHelper urlHelperForActionLink = new UrlHelper(pHtml.ViewContext.RequestContext);
bool flag = Operators.CompareString(pController, "", true) != 0;
string actionLink;
if (flag)
{
actionLink = urlHelperForActionLink.Action(pAction, pController, System.Runtime.CompilerServices.RuntimeHelpers.GetObjectValue(pRouteValues));
}
else
{
actionLink = urlHelperForActionLink.Action(pAction, System.Runtime.CompilerServices.RuntimeHelpers.GetObjectValue(pRouteValues));
}
string onClickEventJavascript = "this.form.action = '" + actionLink + "'; this.form.submit();";
TagBuilder btnTagBuilder = new TagBuilder("input");
btnTagBuilder.MergeAttribute("type", "button");
btnTagBuilder.MergeAttribute("onClick", onClickEventJavascript);
flag = (Operators.CompareString(pBtnValue, "", true) != 0);
if (flag)
{
btnTagBuilder.MergeAttribute("value", pBtnValue);
}

return MvcHtmlString.Create(btnTagBuilder.ToString(TagRenderMode.Normal));
}
These methods have various parameters, but for the ease of use you can create some overload that take just the parameters you need.
One possible reason to catch-throw is to disable any exception filters deeper up the stack from filtering down (random old link). But of course, if that was the intention, there would be a comment there saying so.

The fact that Clang compiles code faster may not be as important as the speed of the resulting binary. However, here is a series of benchmarks.
I know the thread is too old to post an answer. But still i think it is worth it.
Though you can't have an explicit constructor, if your intention is to call the constructor of the super class, then the following is all you have to do.
StoredProcedure sp = new StoredProcedure(datasource, spName) {
{// init code if there are any}
};
This is an example of creating a StoredProcedure
object in Spring by passing a DataSource
and a String
object.
So the Bottom line is, if you want to create an anonymous class and want to call the super class constructor then create the anonymous class with a signature matching the super class constructor.
The way via unlist
and matrix
seems a bit convoluted, and requires you to hard-code the number of elements (this is actually a pretty big no-go. Of course you could circumvent hard-coding that number and determine it at run-time)
I would go a different route, and construct a data frame directly from the list that strsplit
returns. For me, this is conceptually simpler. There are essentially two ways of doing this:
as.data.frame
– but since the list is exactly the wrong way round (we have a list of rows rather than a list of columns) we have to transpose the result. We also clear the rownames
since they are ugly by default (but that’s strictly unnecessary!):
`rownames<-`(t(as.data.frame(strsplit(text, '\\.'))), NULL)
Alternatively, use rbind
to construct a data frame from the list of rows. We use do.call
to call rbind
with all the rows as separate arguments:
do.call(rbind, strsplit(text, '\\.'))
Both ways yield the same result:
[,1] [,2] [,3] [,4]
[1,] "F" "US" "CLE" "V13"
[2,] "F" "US" "CA6" "U13"
[3,] "F" "US" "CA6" "U13"
[4,] "F" "US" "CA6" "U13"
[5,] "F" "US" "CA6" "U13"
[6,] "F" "US" "CA6" "U13"
…
Clearly, the second way is much simpler than the first.
We can use LIMIT like bellow:
Model::take(20)->get();
For me the solution was to change the view model. Consider you are searching for invoices. These invoices can be paid or not. So your search has three options: Paid, Unpaid, or "I don't Care".
I had this originally set as a bool? field:
public bool? PaidInvoices { get; set; }
This made me stumble onto this question. I ended up created an Enum type and I handled this as follows:
@Html.RadioButtonFor(m => m.PaidInvoices, PaidStatus.NotSpecified, new { @checked = true })
@Html.RadioButtonFor(m => m.PaidInvoices, PaidStatus.Yes)
@Html.RadioButtonFor(m => m.PaidInvoices, PaidStatus.No)
Of course I had them wrapped in labels and had text specified, I just mean here's another option to consider.
@Martin Konecny's answer provides the correct answer, but - as he mentions - it only works if the actual script is not invoked through a symlink residing in a different directory.
This answer covers that case: a solution that also works when the script is invoked through a symlink or even a chain of symlinks:
Linux / GNU readlink
solution:
If your script needs to run on Linux only or you know that GNU readlink
is in the $PATH
, use readlink -f
, which conveniently resolves a symlink to its ultimate target:
scriptDir=$(dirname -- "$(readlink -f -- "$BASH_SOURCE")")
Note that GNU readlink
has 3 related options for resolving a symlink to its ultimate target's full path: -f
(--canonicalize
), -e
(--canonicalize-existing
), and -m
(--canonicalize-missing
) - see man readlink
.
Since the target by definition exists in this scenario, any of the 3 options can be used; I've chosen -f
here, because it is the most well-known one.
Multi-(Unix-like-)platform solution (including platforms with a POSIX-only set of utilities):
If your script must run on any platform that:
has a readlink
utility, but lacks the -f
option (in the GNU sense of resolving a symlink to its ultimate target) - e.g., macOS.
readlink
; note that recent versions of FreeBSD/PC-BSD do support -f
.does not even have readlink
, but has POSIX-compatible utilities - e.g., HP-UX (thanks, @Charles Duffy).
The following solution, inspired by https://stackoverflow.com/a/1116890/45375,
defines helper shell function, rreadlink()
, which resolves a given symlink to its ultimate target in a loop - this function is in effect a POSIX-compliant implementation of GNU readlink
's -e
option, which is similar to the -f
option, except that the ultimate target must exist.
Note: The function is a bash
function, and is POSIX-compliant only in the sense that only POSIX utilities with POSIX-compliant options are used. For a version of this function that is itself written in POSIX-compliant shell code (for /bin/sh
), see here.
If readlink
is available, it is used (without options) - true on most modern platforms.
Otherwise, the output from ls -l
is parsed, which is the only POSIX-compliant way to determine a symlink's target.
Caveat: this will break if a filename or path contains the literal substring ->
- which is unlikely, however.
(Note that platforms that lack readlink
may still provide other, non-POSIX methods for resolving a symlink; e.g., @Charles Duffy mentions HP-UX's find
utility supporting the %l
format char. with its -printf
primary; in the interest of brevity the function does NOT try to detect such cases.)
An installable utility (script) form of the function below (with additional functionality) can be found as rreadlink
in the npm registry; on Linux and macOS, install it with [sudo] npm install -g rreadlink
; on other platforms (assuming they have bash
), follow the manual installation instructions.
If the argument is a symlink, the ultimate target's canonical path is returned; otherwise, the argument's own canonical path is returned.

Column
tries to expands in vertical axis, and so does the ListView
, hence you need to constrain the height of ListView
.
Solutions
Use either Expanded
or Flexible
if you want to allow ListView
to take up entire left space in Column
.
Column(
children: <Widget>[
Expanded(
child: ListView(...),
)
],
)
Use SizedBox
if you want to restrict the size of ListView
to a certain height.
Column(
children: <Widget>[
SizedBox(
height: 200, // constrain height
child: ListView(),
)
],
)
Use shrinkWrap
, if your ListView
isn't too big.
Column(
children: <Widget>[
ListView(
shrinkWrap: true, // use it
)
],

One issue that had me for an hour or more, on DecimalFormat
- It handles double and float inputs differently. Even change of RoundingMode did not help. I am no expert but thought it may help someone like me. Ended up using Math.round
instead.
See below:
DecimalFormat df = new DecimalFormat("#.##");
double d = 0.7750;
System.out.println(" Double 0.7750 -> " +Double.valueOf(df.format(d)));
float f = 0.7750f;
System.out.println(" Float 0.7750f -> "+Float.valueOf(df.format(f)));
// change the RoundingMode
df.setRoundingMode(RoundingMode.HALF_UP);
System.out.println(" Rounding Up Double 0.7750 -> " +Double.valueOf(df.format(d)));
System.out.println(" Rounding Up Float 0.7750f -> " +Float.valueOf(df.format(f)));
Output:
Double 0.7750 -> 0.78
Float 0.7750f -> 0.77
Rounding Up Double 0.7750 -> 0.78
Rounding Up Float 0.7750f -> 0.77
You can use maxlength
to limit the length. Normally for numeric input you'd use type="number"
, however this adds a spinny box thing to scroll through numbers, which is completely useless for phone numbers. You can, however, use the pattern
attribute to limit input to numbers (and require 10 numbers too, if you want):
<input type="text" maxlength="10" pattern="\d{10}" title="Please enter exactly 10 digits" />
The file path "c:\Test\blah"
will have a tab character for the `\T'. You need to use either:
"C:\\Test"
or
r"C:\Test"
Make sure you have ipykernel
installed and use ipython kernel install
to drop the kernelspec in the right location for python2. Then ipython3 kernel install
for Python3. Now you should be able to chose between the 2 kernels regardless of whether you use jupyter notebook
, ipython notebook
or ipython3 notebook
(the later two are deprecated).
Note that if you want to install for a specific Python executable you can use the following trick:
path/to/python -m ipykernel install <options>
This works when using environments (venv,conda,...) and the <options>
let you name your kernel (see --help
). So you can do
conda create -n py36-test python=3.6
source activate py36-test
python -m ipykernel install --name py36-test
source deactivate
And now you get a kernel named py36-test
in your dropdown menus, along the other ones.

Client-side validation was not being executed at all on my web form and I had no idea why. It turns out the problem was the name of the javascript function was the same as the server control ID.
So you can't do this...
<script>
function vld(sender, args) { args.IsValid = true; }
</script>
<asp:CustomValidator runat="server" id="vld" ClientValidationFunction="vld" />
But this works:
<script>
function validate_vld(sender, args) { args.IsValid = true; }
</script>
<asp:CustomValidator runat="server" id="vld" ClientValidationFunction="validate_vld" />
I'm guessing it conflicts with internal .NET Javascript?

In those situations where I needed a true infinite loop, I've always used
while(true) {...}
It seems to express intent better than an empty for statement.
You could use the library lxml (Note top level link is now spam) , which is a superset of ElementTree. Its tostring() method includes a parameter pretty_print - for example:

I got this error message because I had the div tag on the partial view instead of the parent view
This will only give you marginal protection. If the attacker can run arbitrary code in your application they can get at the passwords in exactly the same way your application can. You could still get some protection from some SQL injection attacks and misplaced db backups if you store a secret key in a file and use that to encrypt on the way to the db and decrypt on the way out. But you should use bindparams to completely avoid the issue of SQL injection.
If decide to encrypt, you should use some high level crypto library for this, or you will get it wrong. You'll have to get the key-setup, message padding and integrity checks correct, or all your encryption effort is of little use. GPGME is a good choice for one example. Mcrypt is too low level and you will probably get it wrong.
I think (from experimenting - MSDN is unhelpful here) that there is no direct way of doing this. Setting Criteria1
to an Array
is equivalent to using the tick boxes in the dropdown - as you say it will only filter a list based on items that match one of those in the array.
Interestingly, if you have the literal values "<>A"
and "<>B"
in the list and filter on these the macro recorder comes up with
Range.AutoFilter Field:=1, Criteria1:="=<>A", Operator:=xlOr, Criteria2:="=<>B"
which works. But if you then have the literal value "<>C"
as well and you filter for all three (using tick boxes) while recording a macro, the macro recorder replicates precisely your code which then fails with an error. I guess I'd call that a bug - there are filters you can do using the UI which you can't do with VBA.
Anyway, back to your problem. It is possible to filter values not equal to some criteria, but only up to two values which doesn't work for you:
Range("$A$1:$A$9").AutoFilter Field:=1, Criteria1:="<>A", Criteria2:="<>B", Operator:=xlAnd
There are a couple of workarounds possible depending on the exact problem:
=ISNUMBER(A2)
or =NOT(A2="A", A2="B", A2="C")
then filter on TRUE
Criteria1:=">-65535"
(or a suitable number lower than any you expect) which will filter out non-numeric values - assuming this is what you wantFor example:
Public Sub hideABCRows(rangeToFilter As Range)
Dim oCurrentCell As Range
On Error GoTo errHandler
Application.ScreenUpdating = False
For Each oCurrentCell In rangeToFilter.Cells
If oCurrentCell.Value = "A" Or oCurrentCell.Value = "B" Or oCurrentCell.Value = "C" Then
oCurrentCell.EntireRow.Hidden = True
End If
Next oCurrentCell
Application.ScreenUpdating = True
Exit Sub
errHandler:
Application.ScreenUpdating = True
End Sub
A possible solutions is to declare a second bean which reads from the same properties file:
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="/WEB-INF/app.properties" />
</bean>
<util:properties id="appProperties" location="classpath:/WEB-INF/app.properties"/>
The bean named 'appProperties' is of type java.util.Properties and can be dependency injected using the @Resource attruibute shown above.
First of all, my response to the question you've originally asked
Q: How do I discover if a variable is defined at a point in my code?
A: Read up in the source file until you see a line where that variable is defined.
But further, you've given a code example that there are various permutations of that are quite pythonic. You're after a way to scan a sequence for elements that match a condition, so here are some solutions:
def findFirstMatch(sequence):
for value in sequence:
if matchCondition(value):
return value
raise LookupError("Could not find match in sequence")
Clearly in this example you could replace the raise
with a return None
depending on what you wanted to achieve.
If you wanted everything that matched the condition you could do this:
def findAllMatches(sequence):
matches = []
for value in sequence:
if matchCondition(value):
matches.append(value)
return matches
There is another way of doing this with yield
that I won't bother showing you, because it's quite complicated in the way that it works.
Further, there is a one line way of achieving this:
all_matches = [value for value in sequence if matchCondition(value)]
Add to doc header:
\usepackage{ amssymb }
Then at the desired location add:
$ \blacksquare $
If your directory structure is like this,
site
application
controller
folder_1
first_controller.php
second_controller.php
folder_2
first_controller.php
second_controller.php
And when you are going to redirect it in same controller in which you are working then just write the following code.
$this->load->helper('url');
if ($some_value === FALSE/TRUE) //You may give 0/1 as well,its up to your logic
{
redirect('same_controller/method', 'refresh');
}
And if you want to redirect to another control then use the following code.
$this->load->helper('url');
if ($some_value === FALSE/TRUE) //You may give 0/1 as well,its up to your logic
{
redirect('folder_name/any_controller_name/method', 'refresh');
}

If you are in Eclipse and have installed Egit then you can rename the repository that contains a project by doing the following:
1) In Eclipse: Close all projects that are in the repository.
2) In the file system: Locate the directory/folder that contains the repository.
3) In the file system: Rename the directory/folder that contains the repository.
4) In the file system: Open the directory/folder that contains the repository and rename the project directory/folder of any project you intend to rename so that it will match the new name of the project. (This is not required but it gives consistency between the project name in Eclipse and the project directory/folder in the repository.)
5) In Eclipse: Delete all projects that are in the repository but be sure to NOT check the 'Delete the contents from the file system' checkbox. (The project should no longer contain the correct location of the contents of the file system so the data could not be deleted in any case but it is better to be safe than sorry.)
6) In Eclipse: From the Menu select the File|Import... option.
7) In Eclipse: In dialog box open the 'Git' folder, select 'Projects from Git' and click 'Next'.
8) In Eclipse: In dialog box select 'Local' and click 'Next'.
9) In Eclipse: In dialog box click the 'Add...' button.
10) In Eclipse: In dialog box make sure the check box next to the repository is checked and click 'Finish'.
11) In Eclipse: In dialog box select the repository and click 'Next'.
12) In Eclipse: In dialog box select the 'Import existing projects' radio button, select the "Working Directory" and click 'Next'.
13) In Eclipse: In dialog box check the check box next to the projects you want to work on and click 'Finish'.
14) In Eclipse: Rename any the projects that are in the repository if so desired. (For consistency between Eclipse and the file system give them the same name as the project directory/folder inside the repository directory/folder.)
UPDATE: I have taken all of your input and came up with the following solution:
In code behind:
protected void Page_Load(object sender, EventArgs e)
{
Page.ClientScript.RegisterOnSubmitStatement(typeof(Page), "closePage", "window.onunload = CloseWindow();");
}
In aspx page:
function CloseWindow() {
window.close();
}
It's not clear what you want, or whether you want this trick to work with different targets, or whether you've defined these targets elsewhere, or what version of Make you're using, but what the heck, I'll go out on a limb:
ifeq (yes, ${TEST})
CXXFLAGS := ${CXXFLAGS} -DDESKTOP_TEST
test:
$(info ************ TEST VERSION ************)
else
release:
$(info ************ RELEASE VERSIOIN **********)
endif
var full_url = document.URL; // Get current url
var url_array = full_url.split('/') // Split the string into an array with / as separator
var last_segment = url_array[url_array.length-1]; // Get the last part of the array (-1)
alert( last_segment ); // Alert last segment
Your rewrite rule looks almost ok.
First make sure that your .htaccess
file is in your document root (the same place as index.php
) or it'll only affect the sub-folder it's in (and any sub-folders within that - recursively).
Next make a slight change to your rule so it looks something like:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?path=$1 [NC,L,QSA]
At the moment you're just matching on .
which is one instance of any character, you need at least .*
to match any number of instances of any character.
The $_GET['path']
variable will contain the fake directory structure, so /mvc/module/test
for instance, which you can then use in index.php to determine the Controller and actions you want to perform.
If you want the whole shebang installed in a sub-directory, such as /mvc/
or /framework/
the least complicated way to do it is to change the rewrite rule slightly to take that into account.
RewriteRule ^(.*)$ /mvc/index.php?path=$1 [NC,L,QSA]
And ensure that your index.php
is in that folder whilst the .htaccess
file is in the document root.
Alternative to $_GET['path']
(updated Feb '18 and Jan '19)
It's not actually necessary (nor even common now) to set the path as a $_GET
variable, many frameworks will rely on $_SERVER['REQUEST_URI']
to retrieve the same information - normally to determine which Controller to use - but the principle is exactly the same.
This does simplify the RewriteRule
slightly as you don't need to create the path parameter (which means the OP's original RewriteRule
will now work):
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ /index.php [L,QSA]
However, the rule about installing in a sub-directory still applies, e.g.
RewriteRule ^.*$ /mvc/index.php [L,QSA]
The flags:
NC
= No Case (not case sensitive, not really necessary since there are no characters in the pattern)
L
= Last (it'll stop rewriting at after this Rewrite so make sure it's the last thing in your list of rewrites)
QSA
= Query String Append, just in case you've got something like ?like=penguins
on the end which you want to keep and pass to index.php.
This is a big topic. The Spring reference doc devotes multiple chapters to it. I recommend reading the ones on Aspect-Oriented Programming and Transactions, as Spring's declarative transaction support uses AOP at its foundation.
But at a very high level, Spring creates proxies for classes that declare @Transactional on the class itself or on members. The proxy is mostly invisible at runtime. It provides a way for Spring to inject behaviors before, after, or around method calls into the object being proxied. Transaction management is just one example of the behaviors that can be hooked in. Security checks are another. And you can provide your own, too, for things like logging. So when you annotate a method with @Transactional, Spring dynamically creates a proxy that implements the same interface(s) as the class you're annotating. And when clients make calls into your object, the calls are intercepted and the behaviors injected via the proxy mechanism.
Transactions in EJB work similarly, by the way.
As you observed, through, the proxy mechanism only works when calls come in from some external object. When you make an internal call within the object, you're really making a call through the "this" reference, which bypasses the proxy. There are ways of working around that problem, however. I explain one approach in this forum post in which I use a BeanFactoryPostProcessor to inject an instance of the proxy into "self-referencing" classes at runtime. I save this reference to a member variable called "me". Then if I need to make internal calls that require a change in the transaction status of the thread, I direct the call through the proxy (e.g. "me.someMethod()".) The forum post explains in more detail. Note that the BeanFactoryPostProcessor code would be a little different now, as it was written back in the Spring 1.x timeframe. But hopefully it gives you an idea. I have an updated version that I could probably make available.

I have been having the same problem. I followed Bruno's advice to you and found that adding a KeyListener just to the "first" button in the JFrame (ie, on the top left) did the trick. But I agree with you it is kind of an unsettling solution. So I fiddled around and discovered a neater way to fix it. Just add the line
myChildOfJFrame.requestFocusInWindow();
to your main method, after you've created your instance of your subclass of JFrame and set it visible.
In cases when a parameter name cannot be hardcoded I found this would be the simplest and best way to access parameters:
def myParam = env.getProperty(dynamicParamName)
In cases, when a parameter name is known and can be hardcoded the following 3 lines are equivalent:
def myParam = env.getProperty("myParamName")
def myParam = env.myParamName
def myParam = myParamName
The Java EE version of Eclipse is not installed, insted a standard SDK version is installed.

Tagging of the image isn't supported inside the Dockerfile. This needs to be done in your build command. As a workaround, you can do the build with a docker-compose.yml that identifies the target image name and then run a docker-compose build
. A sample docker-compose.yml would look like
version: '2'
services:
man:
build: .
image: dude/man:v2
That said, there's a push against doing the build with compose since that doesn't work with swarm mode deploys. So you're back to running the command as you've given in your question:
docker build -t dude/man:v2 .
Personally, I tend to build with a small shell script in my folder (build.sh) which passes any args and includes the name of the image there to save typing. And for production, the build is handled by a ci/cd server that has the image name inside the pipeline script.
To answer the second part of your question, to convert to binary you can use a format string and the ord
function:
>>> byte = 'a'
>>> '{0:08b}'.format(ord(byte))
'01100001'
Note that the format pads with the right number of leading zeros, which seems to be your requirement. This method needs Python 2.6 or later.
My observations regarding the HTML 5 video tag and rtsp(rtp) streams are, that it only works with konqueror(KDE 4.4.1, Phonon-backend set to GStreamer). I got only video (no audio) with a H.264/AAC RTSP(RTP) stream.
The streams from http://media.esof2010.org/ didn't work with konqueror(KDE 4.4.1, Phonon-backend set to GStreamer).
The default value of error_reporting flag is E_ALL & ~E_NOTICE if not set in php.ini. But in some installation (particularly installations targeting development environments) has E_ALL | E_STRICT set as value of this flag (this is the recommended value during development). In some cases, specially when you'll want to run some open source projects, that was developed prior to PHP 5.3 era and not yet updated with best practices defined by PHP 5.3, in your development environment, you'll probably run into getting some messages like you are getting. The best way to cope up on this situation, is to set only E_ALL as the value of error_reporting flag, either in php.ini or in code (probably in a front-controller like index.php in web-root as follows:
if(defined('E_STRICT')){
error_reporting(E_ALL);
}

I thought I would add some extra bits, for tips and tricks that have come up.
One question I see come up a fair bit, is How do I get non-matching rows from two tables and I see the answer most commonly accepted as something like the following (based on our cars and brands table - which has Holden listed as a brand, but does not appear in the cars table):
select
a.ID,
a.brand
from
brands a
where
a.ID not in(select brand from cars)
And yes it will work.
+----+--------+
| ID | brand |
+----+--------+
| 6 | Holden |
+----+--------+
1 row in set (0.00 sec)
However it is not efficient in some database. Here is a link to a Stack Overflow question asking about it, and here is an excellent in depth article if you want to get into the nitty gritty.
The short answer is, if the optimiser doesn't handle it efficiently, it may be much better to use a query like the following to get non matched rows:
select
a.brand
from
brands a
left join cars b
on a.id=b.brand
where
b.brand is null
+--------+
| brand |
+--------+
| Holden |
+--------+
1 row in set (0.00 sec)
Ahhh, another oldie but goodie - the old You can't specify target table 'brands' for update in FROM clause.
MySQL will not allow you to run an update...
query with a subselect on the same table. Now, you might be thinking, why not just slap it into the where clause right? But what if you want to update only the row with the max()
date amoung a bunch of other rows? You can't exactly do that in a where clause.
update
brands
set
brand='Holden'
where
id=
(select
id
from
brands
where
id=6);
ERROR 1093 (HY000): You can't specify target table 'brands'
for update in FROM clause
So, we can't do that eh? Well, not exactly. There is a sneaky workaround that a surprisingly large number of users don't know about - though it does include some hackery that you will need to pay attention to.
You can stick the subquery within another subquery, which puts enough of a gap between the two queries so that it will work. However, note that it might be safest to stick the query within a transaction - this will prevent any other changes being made to the tables while the query is running.
update
brands
set
brand='Holden'
where id=
(select
id
from
(select
id
from
brands
where
id=6
)
as updateTable);
Query OK, 0 rows affected (0.02 sec)

Yes, your serving of the policy file can definitely cause the crash.
To repeat, just add a delay to your code:
net.createServer( function(socket)
{
for (i=0; i<1000000000; i++) ;
socket.write("<?xml version=\"1.0\"?>\n");
…
… and use telnet
to connect to the port. If you disconnect telnet before the delay has expired, you'll get a crash (uncaught exception) when socket.write throws an error.
To avoid the crash here, just add an error handler before reading/writing the socket:
net.createServer(function(socket)
{
for(i=0; i<1000000000; i++);
socket.on('error', function(error) { console.error("error", error); });
socket.write("<?xml version=\"1.0\"?>\n");
}
When you try the above disconnect, you'll just get a log message instead of a crash.
And when you're done, remember to remove the delay.
It can also occur if you leave an element with a null or empty attribute in your XML layout file else if your java file's path of objects creation such as specifying improper ID for the object
here frombottom= AnimationUtils.loadAnimation(this,R.anim);
in which anim. the id or filename is left blank can lead to such problem.
The answers above are correct: it is used in exception handling. The manual for GCC version 6 has more information (which is no longer present in the version 7 manual). The error can arise when linking an external function that - unknown to GCC - throws Java exceptions.

The more general answer to this question involves shadowed variables and how they are accessed.
In the following example (from Oracle), the variable x in main() is shadowing Test.x:
class Test {
static int x = 1;
public static void main(String[] args) {
InnerClass innerClassInstance = new InnerClass()
{
public void printX()
{
System.out.print("x=" + x);
System.out.println(", Test.this.x=" + Test.this.x);
}
}
innerClassInstance.printX();
}
public abstract static class InnerClass
{
int x = 0;
public InnerClass() { }
public abstract void printX();
}
}
Running this program will print:
x=0, Test.this.x=1

Unfortunately if you're looking to apply UIPopoverController
in iOS9, you'll get a deprecated class warning. Instead you need to set your desired view's UIModalPresentationPopover
property to achieve the same result.
Popover
In a horizontally regular environment, a presentation style where the content is displayed in a popover view. The background content is dimmed and taps outside the popover cause the popover to be dismissed. If you do not want taps to dismiss the popover, you can assign one or more views to the passthroughViews property of the associated UIPopoverPresentationController object, which you can get from the popoverPresentationController property.
In a horizontally compact environment, this option behaves the same as UIModalPresentationFullScreen.
Available in iOS 8.0 and later.
Reference: https://developer.apple.com/documentation/uikit/uiviewcontroller/1621355-modalpresentationstyle

You can customize the location of your Toast by using:
setGravity(int gravity, int xOffset, int yOffset)
This allows you to be very specific about where you want the location of your Toast to be.
One of the most useful things about the xOffset and yOffset parameters is that you can use them to place the Toast relative to a certain View.
For example, if you want to make a custom Toast that appears on top of a Button, you could create a function like this:
// v is the Button view that you want the Toast to appear above
// and messageId is the id of your string resource for the message
private void displayToastAboveButton(View v, int messageId)
{
int xOffset = 0;
int yOffset = 0;
Rect gvr = new Rect();
View parent = (View) v.getParent();
int parentHeight = parent.getHeight();
if (v.getGlobalVisibleRect(gvr))
{
View root = v.getRootView();
int halfWidth = root.getRight() / 2;
int halfHeight = root.getBottom() / 2;
int parentCenterX = ((gvr.right - gvr.left) / 2) + gvr.left;
int parentCenterY = ((gvr.bottom - gvr.top) / 2) + gvr.top;
if (parentCenterY <= halfHeight)
{
yOffset = -(halfHeight - parentCenterY) - parentHeight;
}
else
{
yOffset = (parentCenterY - halfHeight) - parentHeight;
}
if (parentCenterX < halfWidth)
{
xOffset = -(halfWidth - parentCenterX);
}
if (parentCenterX >= halfWidth)
{
xOffset = parentCenterX - halfWidth;
}
}
Toast toast = Toast.makeText(getActivity(), messageId, Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, xOffset, yOffset);
toast.show();
}

The shortest one I could come up with is:
chmod -R a=r,u+w,a+X /foo
which works on GNU/Linux, and I believe on Posix in general (from my reading of: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/chmod.html).
What this does is:
Importantly, the step 1 permission clears all execute bits, so step 3 only adds back execute bits for directories (never files). In addition, all three steps happen before a directory is recursed into (so this is not equivalent to e.g.
chmod -R a=r /foo
chmod -R u+w /foo
chmod -R a+X /foo
since the a=r removes x from directories, so then chmod can't recurse into them.)
Easiest method is to type:

files before .py

The TextBoxFor
is a newer MVC input extension introduced in MVC2.
The main benefit of the newer strongly typed extensions is to show any errors / warnings at compile-time rather than runtime.

DATE_FORMAT(column name, '%Y-%m-%d %T') as dtime
Use this to avoid the error. It return the date in string format and then you can get it as a string.
resultset.getString("dtime");
This actually does NOT work. Even though you call getString. Internally mysql still tries to convert it to date first.

Based on KMier's answer, addresses the comment that this method poses a problem when the field to be padded is not a field, but the outcome of a (possibly complicated) function; the entire function has to be repeated.
Also, this allows for padding a field to the maximum length of its contents.
WITH
cte AS (
SELECT 'foo' AS value_to_be_padded
UNION SELECT 'foobar'
),
cte_max AS (
SELECT MAX(LEN(value_to_be_padded)) AS max_len
)
SELECT
CONCAT(SPACE(max_len - LEN(value_to_be_padded)), value_to_be_padded AS left_padded,
CONCAT(value_to_be_padded, SPACE(max_len - LEN(value_to_be_padded)) AS right_padded;
libiconv is a great library for all our encoding and decoding needs.

This option comes in curl 7.73.0:
curl --create-dirs -O --output-dir /tmp/receipes https://example.com/pancakes.jpg
Through discourse it's clear that the problem lies in using VS2010 to write the query, as it uses the canonical CONCAT()
function which is limited to 2 parameters. There's probably a way to change that, but I'm not aware of it.
An alternative:
SELECT '1'+'2'+'3'
This approach requires non-string values to be cast/converted to strings, as well as NULL
handling via ISNULL()
or COALESCE()
:
SELECT ISNULL(CAST(Col1 AS VARCHAR(50)),'')
+ COALESCE(CONVERT(VARCHAR(50),Col2),'')
The package broom
comes in handy here (it uses the "tidy" format).
tidy(mg)
will give a nicely formated data.frame with coefficients, t statistics etc. Works also for other models (e.g. plm, ...).
Example from broom
's github repo:
lmfit <- lm(mpg ~ wt, mtcars)
require(broom)
tidy(lmfit)
term estimate std.error statistic p.value
1 (Intercept) 37.285 1.8776 19.858 8.242e-19
2 wt -5.344 0.5591 -9.559 1.294e-10
is.data.frame(tidy(lmfit))
[1] TRUE
ArrayList newArrayList = (ArrayList) oldArrayList.clone();
You need to do type assertion for converting your interface{} to int value.
iAreaId := val.(int)
iAreaId, ok := val.(int)
More information is available.
From React's documentation:
setState()
does not immediately mutatethis.state
but creates a pending state transition. Accessingthis.state
after calling this method can potentially return the existing value. There is no guarantee of synchronous operation of calls tosetState
and calls may be batched for performance gains.
If you want a function to be executed after the state change occurs, pass it in as a callback.
this.setState({value: event.target.value}, function () {
console.log(this.state.value);
});
The safest way to avoid events on an href would be to define it as

Ahhhh, now it is clear. You seem to have problems binding back the value. Not with displaying it on the view. Indeed, that's the fault of the default model binder. You could write and use a custom one that will take into consideration the [DisplayFormat]
attribute on your model. I have illustrated such a custom model binder here: https://stackoverflow.com/a/7836093/29407
Apparently some problems still persist. Here's my full setup working perfectly fine on both ASP.NET MVC 3 & 4 RC.
Model:
public class MyViewModel
{
[DisplayName("date of birth")]
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
public DateTime? Birth { get; set; }
}
Controller:
public class HomeController : Controller
{
public ActionResult Index()
{
return View(new MyViewModel
{
Birth = DateTime.Now
});
}
[HttpPost]
public ActionResult Index(MyViewModel model)
{
return View(model);
}
}
View:
@model MyViewModel
@using (Html.BeginForm())
{
@Html.LabelFor(x => x.Birth)
@Html.EditorFor(x => x.Birth)
@Html.ValidationMessageFor(x => x.Birth)
<button type="submit">OK</button>
}
Registration of the custom model binder in Application_Start
:
ModelBinders.Binders.Add(typeof(DateTime?), new MyDateTimeModelBinder());
And the custom model binder itself:
public class MyDateTimeModelBinder : DefaultModelBinder
{
public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
if (!string.IsNullOrEmpty(displayFormat) && value != null)
{
DateTime date;
displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
// use the format specified in the DisplayFormat attribute to parse the date
if (DateTime.TryParseExact(value.AttemptedValue, displayFormat, CultureInfo.InvariantCulture, DateTimeStyles.None, out date))
{
return date;
}
else
{
bindingContext.ModelState.AddModelError(
bindingContext.ModelName,
string.Format("{0} is an invalid date format", value.AttemptedValue)
);
}
}
return base.BindModel(controllerContext, bindingContext);
}
}
Now, no matter what culture you have setup in your web.config (<globalization>
element) or the current thread culture, the custom model binder will use the DisplayFormat
attribute's date format when parsing nullable dates.
Heres a solution with no Javascript or plugin - just some css and one extra class in the markup. This solutions uses the fact that BootStrap adds a class to the body when a dialog is open. We use this class to then hide the body, and print only the dialog.
To ensure we can determine the main body of the page we need to contain everything within the main page content in a div - I've used id="mainContent". Sample Page layout below - with a main page and two dialogs
<body>
<div class="container body-content">
<div id="mainContent">
main page stuff
</div>
<!-- Dialog One -->
<div class="modal fade in">
<div class="modal-dialog">
<div class="modal-content">
...
</div>
</div>
</div>
<!-- Dialog Two -->
<div class="modal fade in">
<div class="modal-dialog">
<div class="modal-content">
...
</div>
</div>
</div>
</div>
</body>
Then in our CSS print media queries, I use display: none to hide everything I don't want displayed - ie the mainContent when a dialog is open. I also use a specific class noPrint to be used on any parts of the page that should not be displayed - say action buttons. Here I am also hiding the headers and footers. You may need to tweak it to get exactly want you want.
@media print {
header, .footer, footer {
display: none;
}
/* hide main content when dialog open */
body.modal-open div.container.body-content div#mainContent {
display: none;
}
.noPrint {
display: none;
}
}
an alternative would be to do something like:
SELECT
CAST(P0.seconds as bigint) as seconds
FROM
(
SELECT
seconds
FROM
TableName
WHERE
ISNUMERIC(seconds) = 1
) P0
You could use an anonymous function:
var counter = 10;
var myFunction = function(){
clearInterval(interval);
counter *= 10;
interval = setInterval(myFunction, counter);
}
var interval = setInterval(myFunction, counter);
UPDATE: As suggested by A. Wolff, use setTimeout
to avoid the need for clearInterval
.
var counter = 10;
var myFunction = function() {
counter *= 10;
setTimeout(myFunction, counter);
}
setTimeout(myFunction, counter);

It is a tradition to use Turbo C for graphic in C/C++. But it’s also a pain in the neck. We are using Code::Blocks IDE, which will ease out our work.
Steps to run graphics code in CodeBlocks:
To test the setting copy paste run following code:
#include <graphics.h>
int main( )
{
initwindow(400, 300, "First Sample");
circle(100, 50, 40);
while (!kbhit( ))
{
delay(200);
}
return 0;
}
Here is a complete setup instruction for Code::Blocks
There is something about Array.fill
I need to mention.
If you just use below method to create a 3x3 matrix.
Array(3).fill(Array(3).fill(0));
You will find that the values in the matrix is a reference.
If you want to pass by value rather than reference, you can leverage Array.map
to create it.
Array(3).fill(null).map(() => Array(3).fill(0));
Assuming you're passing in strings rather than integers, try casting the arguments to integers:
def example(arg1, arg2, arg3):
if int(arg1) == 1 and int(arg2) == 2 and int(arg3) == 3:
print("Example Text")
(Edited to emphasize I'm not asking for clarification; I was trying to be diplomatic in my answer. )
The answer that has 50 votes doesn't check for date in only checks for months. That answer is not correct. The code below works.
var dateFrom = "01/08/2017";
var dateTo = "01/10/2017";
var dateCheck = "05/09/2017";
var d1 = dateFrom.split("/");
var d2 = dateTo.split("/");
var c = dateCheck.split("/");
var from = new Date(d1); // -1 because months are from 0 to 11
var to = new Date(d2);
var check = new Date(c);
alert(check > from && check < to);
This is the code posted in another answer and I have changed the dates and that's how I noticed it doesn't work
var dateFrom = "02/05/2013";
var dateTo = "02/09/2013";
var dateCheck = "07/07/2013";
var d1 = dateFrom.split("/");
var d2 = dateTo.split("/");
var c = dateCheck.split("/");
var from = new Date(d1[2], parseInt(d1[1])-1, d1[0]); // -1 because months are from 0 to 11
var to = new Date(d2[2], parseInt(d2[1])-1, d2[0]);
var check = new Date(c[2], parseInt(c[1])-1, c[0]);
alert(check > from && check < to);
Assuming a simple case, where your field is public
:
List list; // from your method
for(Object x : list) {
Class<?> clazz = x.getClass();
Field field = clazz.getField("fieldName"); //Note, this can throw an exception if the field doesn't exist.
Object fieldValue = field.get(x);
}
But this is pretty ugly, and I left out all of the try-catches, and makes a number of assumptions (public field, reflection available, nice security manager).
If you can change your method to return a List<Foo>
, this becomes very easy because the iterator then can give you type information:
List<Foo> list; //From your method
for(Foo foo:list) {
Object fieldValue = foo.fieldName;
}
Or if you're consuming a Java 1.4 interface where generics aren't available, but you know the type of the objects that should be in the list...
List list;
for(Object x: list) {
if( x instanceof Foo) {
Object fieldValue = ((Foo)x).fieldName;
}
}
No reflection needed :)
Simply use SimpleDateFormat.
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy", java.util.Locale.ENGLISH);
Date myDate = sdf.parse("28/12/2013");
sdf.applyPattern("EEE, d MMM yyyy");
String sMyDate = sdf.format(myDate);
The result is: Sat, 28 Dec 2013
The default constructor is taking "the default" Locale, so be careful using it when you need a specific pattern.
public SimpleDateFormat(String pattern) {
this(pattern, Locale.getDefault(Locale.Category.FORMAT));
}
The other answers only work for a sequence.
For any iterable, to skip the first item:
itercars = iter(cars)
next(itercars)
for car in itercars:
# do work
If you want to skip the last, you could do:
itercars = iter(cars)
# add 'next(itercars)' here if you also want to skip the first
prev = next(itercars)
for car in itercars:
# do work on 'prev' not 'car'
# at end of loop:
prev = car
# now you can do whatever you want to do to the last one on 'prev'
yes, using *arg passing args to a function will make python unpack the values in arg and pass it to the function.
so:

print args

>>> printer(*range(2, 5))
(2, 3, 4)
>>> printer(range(2, 5))
([2, 3, 4],)

As Dirk said, the function you are after is 'read.csv' or one of the other read.table variants. Given your sample data above, I think you will want to do something like this:
setwd("c:/random/directory")
df <- read.csv("myRandomFile.csv", header=TRUE)
All we did in the above was set the directory to where your .csv file is and then read the .csv into a dataframe named df. You can check that the data loaded properly by checking the structure of the object with:
str(df)
Assuming the data loaded properly, you can think go on to perform any number of statistical methods with the data in your data frame. I think summary(df)
would be a good place to start. Learning how to use the help in R will be immensely useful, and a quick read through the help on CRAN will save you lots of time in the future: http://cran.r-project.org/
in my case, the problem got solved only by implementing serializable as below:
@Entity @Table(name = "User" , uniqueConstraints = { @UniqueConstraint(columnNames = {"nam"}) }) public class User extends GenericT implements Serializable
Just try this
android:windowSoftInputMode="adjustNothing"
in the
activity
section of your manifest. Yes, it adjusts nothings, which means the editText will stay where it is when IME is opening. But that's just an little inconvenience that still completely solves the problem of losing focus.
The default logger in Go writes to stderr (2). redirect to file
import (
"syscall"
"os"
)
func main(){
fErr, err = os.OpenFile("Errfile", os.O_APPEND|os.O_WRONLY|os.O_CREATE, 0600)
syscall.Dup2(int(fErr.Fd()), 1) /* -- stdout */
syscall.Dup2(int(fErr.Fd()), 2) /* -- stderr */
}

Note here: the answers from Zane XY and Alan B. Dee are quite good. Yet for those of you who would use Spring Boot now, and Spring Data, here is what would be a more modern answer.
Suppose you have a class such as:
@Entity
class MyClass {
@Id
@GeneratedValue
private Long id;
private String myClassName;
}
Now a JpaRepository
for this would look like
interface MyClassRepository extends JpaRepository {
Collection<MyClass> findByMyClassName(String myClassName);
}
Now your "custom" find by method must spelled Collection<MyClass> findByMyClassName(String myClassName)
precisely because Spring needs to have some mechanism to map this method on MyClass
property myClassName
!
I figured this out because, to me, it seemed natural to find a class by its name semantically, whereas in fact, synatxically you find by myClassName
Cheers
Pipe a command to stdin
Must remove the -t
for it to work:
echo 'touch myfile' | sudo docker exec -i CONTAINER_NAME bash
This can be more convenient that using CLI options sometimes.
Tested with:
sudo docker run --name ub16 -it ubuntu:16.04 bash
then on another shell:
echo 'touch myfile' | sudo docker exec -i ub16 bash
Then on first shell:
ls -l myfile
Tested on Docker 1.13.1, Ubuntu 16.04 host.

Remember that in git
you have:
HEAD
pointer, which tells you what commit you're working onPlease include detailed explanations about:
--hard
,--soft
and--merge
;
In increasing order of dangerous-ness:
--soft
moves HEAD
but doesn't touch the staging area or the working tree.--mixed
moves HEAD
and updates the staging area, but not the working tree.--merge
moves HEAD
, resets the staging area, and tries to move all the changes in your working tree into the new working tree.--hard
moves HEAD
and adjusts your staging area and working tree to the new HEAD
, throwing away everything.concrete use cases and workflows;
--soft
when you want to move to another commit and patch things up without "losing your place". It's pretty rare that you need this.--
# git reset --soft example
touch foo // Add a file, make some changes.
git add foo //
git commit -m "bad commit message" // Commit... D'oh, that was a mistake!
git reset --soft HEAD^ // Go back one commit and fix things.
git commit -m "good commit" // There, now it's right.
--
Use --mixed
(which is the default) when you want to see what things look like at another commit, but you don't want to lose any changes you already have.
Use --merge
when you want to move to a new spot but incorporate the changes you already have into that the working tree.
Use --hard
to wipe everything out and start a fresh slate at the new commit.
I have found that %matplotlib notebook
works better for me than inline with Jupyter notebooks.
Note that you may need to restart the kernel if you were using %matplotlib inline
before.
Update 2019:
If you are running Jupyter Lab you might want to use
%matplotlib widget
The extension of the source file may have meaning to your build system, for example, you might have a rule in your makefile for .cpp
or .c
files, or your compiler (e.g. Microsoft cl.exe
) might compile the file as C or C++ depending on the extension.
Because you have to provide the whole filename to the #include
directive, the header file extension is irrelevant. You can include a .c
file in another source file if you like, because it's just a textual include. Your compiler might have an option to dump the preprocessed output which will make this clear (Microsoft: /P
to preprocess to file, /E
to preprocess to stdout
, /EP
to omit #line
directives, /C
to retain comments)
You might choose to use .hpp
for files that are only relevant to the C++ environment, i.e. they use features that won't compile in C.
This is when a Promise
is completed with .reject()
or an exception was thrown in an async
executed code and no .catch()
did handle the rejection.
A rejected promise is like an exception that bubbles up towards the application entry point and causes the root error handler to produce that output.

I lost like 2 days for that weird error... Why is this still happening in gradle 1.0.0 ? That is very disturbing for newbies... Anyway, thanks for that info i thought it was on my code :)
My solution is almost the same as the original answer but it doesn't worked for me.
So, I gave names for the columns and it works:
painel <- rbind(painel, data.frame("col1" = xtweets$created_at,
"col2" = xtweets$text))
I've ended up with the following working code:
RewriteEngine on
RewriteCond %{THE_REQUEST} /([^.]+)\.php [NC]
RewriteRule ^ /%1 [NC,L,R]
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^ %{REQUEST_URI}.php [NC,L]
Make sure there is an namespace definition (xmlns
) for the namespace your control belong to.
xmlns:myControls="clr-namespace:YourCustomNamespace.Controls;assembly=YourAssemblyName"
<myControls:thecontrol/>
One solution is to create a named class instead of using an anonymous class. Give that named class a constructor that takes whatever parameters you wish and assigns them to class fields:
class MenuActionListener implements ActionListener {
private Color kolorIkony;
public MenuActionListener(Color kolorIkony) {
this.kolorIkony = kolorIkony
}
@Override
public void actionPerformed(ActionEvent e) {
JMenuItem item = (JMenuItem) e.getSource();
IconA icon = (IconA) item.getIcon();
// Use the class field here
textArea.setForeground(kolorIkony);
}
});
Now you can create an instance of this class as usual:
Jmi.addActionListener(new MenuActionListener(getColor(colors[mi]));
I agree with @CS Pei, however this didn't work for me:
split -b=1M -d file.txt file
...as the =
after -b
threw it off. Instead, I simply deleted it and left no space between it and the variable, and used lowercase "m":
split -b1m -d file.txt file
And to append ".txt", we use what @schoon said:
split -b=1m -d file.txt file --additional-suffix=.txt
I had a 188.5MB txt file and I used this command [but with -b5m
for 5.2MB files], and it returned 35 split files all of which were txt files and 5.2MB except the last which was 5.0MB. Now, since I wanted my lines to stay whole, I wanted to split the main file every 1 million lines, but the split
command didn't allow me to even do -100000
let alone "-1000000
, so large numbers of lines to split will not work.
Console.WriteLine won't work. Only Debug.WriteLine() or Trace.WriteLine() will work, in debug mode.
I do the following: include using System.Diagnostics in the test module. Then, use Debug.WriteLine for my output, right click on the test, choose Debug Selected Tests. The result output will now appear in the Output window below. I use Visual Studio 2017 vs 15.8.1, with the default unit test framework VS provides.
Take note of what is printed for x
. You are trying to convert an array (basically just a list) into an int. length-1
would be an array of a single number, which I assume numpy just treats as a float. You could do this, but it's not a purely-numpy solution.
EDIT: I was involved in a post a couple of weeks back where numpy was slower an operation than I had expected and I realised I had fallen into a default mindset that numpy was always the way to go for speed. Since my answer was not as clean as ayhan's, I thought I'd use this space to show that this is another such instance to illustrate that vectorize
is around 10% slower than building a list in Python. I don't know enough about numpy to explain why this is the case but perhaps someone else does?

return rebuilt_to_plot
for t in range(10000):
x = np.arange(1, 15.1, 0.1)
plt.plot(x, f(x))
time_end = datetime.datetime.now()
# Answer by ayhan
def f_1(x):

As @snapshoe says
flush()
sends your SQL statements to the database
commit()
commits the transaction.
When session.autocommit == False
:
commit()
will call flush()
if you set autoflush == True
.
When session.autocommit == True
:
You can't call commit()
if you haven't started a transaction (which you probably haven't since you would probably only use this mode to avoid manually managing transactions).
In this mode, you must call flush()
to save your ORM changes. The flush effectively also commits your data.

This answer is for visual studio 2017 and if you want to read from text file which location is relative to your compiled console application.
first put your textfile (test.txt in this case) into your solution folder. After compiling keep text file in same folder with applicationName.exe
C:\Users\"username"\source\repos\"solutionName"\"solutionName"
#include <iostream>
#include <fstream>
using namespace std;
int main()
{
ifstream inFile;
// open the file stream
inFile.open(".\\test.txt");
// check if opening a file failed
if (inFile.fail()) {
cerr << "Error opeing a file" << endl;
inFile.close();
exit(1);
}
string line;
while (getline(inFile, line))
{
cout << line << endl;
}
// close the file stream
inFile.close();
}
Improving on the solution above by Timmmm to add some extra scaling at the end to ensure that the image fits within the bounds:
public static Bitmap loadBitmap(String path, int orientation, final int targetWidth, final int targetHeight) {
Bitmap bitmap = null;
try {
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(path, options);
// Adjust extents
int sourceWidth, sourceHeight;
if (orientation == 90 || orientation == 270) {
sourceWidth = options.outHeight;
sourceHeight = options.outWidth;
} else {
sourceWidth = options.outWidth;
sourceHeight = options.outHeight;
}
// Calculate the maximum required scaling ratio if required and load the bitmap
if (sourceWidth > targetWidth || sourceHeight > targetHeight) {
float widthRatio = (float)sourceWidth / (float)targetWidth;
float heightRatio = (float)sourceHeight / (float)targetHeight;
float maxRatio = Math.max(widthRatio, heightRatio);
options.inJustDecodeBounds = false;
options.inSampleSize = (int)maxRatio;
bitmap = BitmapFactory.decodeFile(path, options);
} else {
bitmap = BitmapFactory.decodeFile(path);
}
// Rotate the bitmap if required
if (orientation > 0) {
Matrix matrix = new Matrix();
matrix.postRotate(orientation);
bitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
}
// Re-scale the bitmap if necessary
sourceWidth = bitmap.getWidth();
sourceHeight = bitmap.getHeight();
if (sourceWidth != targetWidth || sourceHeight != targetHeight) {
float widthRatio = (float)sourceWidth / (float)targetWidth;
float heightRatio = (float)sourceHeight / (float)targetHeight;
float maxRatio = Math.max(widthRatio, heightRatio);
sourceWidth = (int)((float)sourceWidth / maxRatio);
sourceHeight = (int)((float)sourceHeight / maxRatio);
bitmap = Bitmap.createScaledBitmap(bitmap, sourceWidth, sourceHeight, true);
}
} catch (Exception e) {
}
return bitmap;
}
First you need to turn on virtualization on your machine. To do that, restart your machine. Press F2. Goto BIOS. Make Virtualization Enabled. Press F10. Start windows. Now, goto Extras folder of Android installation folder and find intel-haxm-android.exe. Run it. Start Android Studio. Now, it should allow you to run your program using emulator.
Though there is an alternative above, but that didn't solve mine. In my case, I delete the "git" plugin in ./zshrc and reboot the computer then the issue is gone, I guess the zsh plugin had done something conflict the original git command.
For people using newer versions of the daemon npm module - you need to pass file descriptors instead of strings:
var fs = require('fs');
var stdoutFd = fs.openSync('output.log', 'a');
var stderrFd = fs.openSync('errors.log', 'a');
require('daemon')({
stdout: stdoutFd,
stderr: stderrFd
});

Your DemoApplication
class is in the com.ag.digital.demo.boot
package and your LoginBean
class is in the com.ag.digital.demo.bean
package. By default components (classes annotated with @Component
) are found if they are in the same package or a sub-package of your main application class DemoApplication
. This means that LoginBean
isn't being found so dependency injection fails.
There are a couple of ways to solve your problem:
LoginBean
into com.ag.digital.demo.boot
or a sub-package.scanBasePackages
attribute of @SpringBootApplication
that should be on DemoApplication
.A few of other things that aren't causing a problem, but are not quite right with the code you've posted:
@Service
is a specialisation of @Component
so you don't need both on LoginBean
@RestController
is a specialisation of @Component
so you don't need both on DemoRestController
DemoRestController
is an unusual place for @EnableAutoConfiguration
. That annotation is typically found on your main application class (DemoApplication
) either directly or via @SpringBootApplication
which is a combination of @ComponentScan
, @Configuration
, and @EnableAutoConfiguration
.In my case, previously I use idea to generate entity by database schema, and the persistence.xml
is automatically generated in src/main/java/META-INF
,and according to https://stackoverflow.com/a/23890419/10701129, I move it to src/main/resources/META-INF
, also marked META-INF as source root. It works for me.
But just simply marking original META-INF(that is, src/main/java/META-INF) as source root, doesn't work, which confuses me.
You cannot call orElse
after ifPresent
, the reason is, orElse
is called on an optiional but ifPresent
returns void. So the best approach to achieve is ifPresentOrElse
.
It could be like this:
op.ifPresentOrElse(
(value)
-> { System.out.println(
"Value is present, its: "
+ value); },
()
-> { System.out.println(
"Value is empty"); });
so do the following edit my.cnf:
[mysqld]
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
language = /usr/share/mysql/English
bind-address = xxx.xxx.xxx.xxx
# skip-networking
after edit hit service mysqld restart
login into mysql and hit this query:
GRANT ALL ON foo.* TO bar@'xxx.xxx.xxx.xxx' IDENTIFIED BY 'PASSWORD';
thats it make sure your iptables allow connection from 3306 if not put the following:
iptables -A INPUT -i lo -p tcp --dport 3306 -j ACCEPT
iptables -A OUTPUT -p tcp --sport 3306 -j ACCEPT
I did follow the instructions here and made wkhtmltopdf work for me but I would like to offer a bit of perspective which I discovered while doing my own little dance with wkhtmltopdf
- xvfb
.
This is important because the same reason that causes it to throw the infamous cannot connect to X server
error is also causing it to run with sever limitations even if you do provide it a X server. These limitations include not being able to take multiple input sources, set header and footers, etc (check the Reduced Functionality section of the manual).
wkhtmltox
by itself doesn't require a X11, however it's making use of QT libraries which do. In newever versions of wkthmltox developers made a patch for QT which allows it to run with a X11.
Currently some versions are built against patched QT and some are not. You can check your version by running wkhtmltopds --version
. There should be a line at the end saying Compiled against wkhtmltopdf patched qt.
So, to conclude, if you install and use a version that uses the patched libraries it should work on a linux server without the xvfb
server, as I can confirm.
If you want to write percent (%), duplicate it:
<string name="percent">%1$d%%</string>
label.text = getString(R.string.percent, 75) // Output: 75%.
If you write simply %1$d%
, you will get the error: Format string 'percent' is not a valid format string so it should not be passed to String.format
.

With C++-11 or Boost libs you could consider storing the variable using smart pointers. Consider this MVE where toString()
behaviour depends on bar
being initialized or not:
#include <memory>
#include <sstream>
class Foo {
private:
std::shared_ptr<int> bar;
public:
Foo() {}
void setBar(int bar) {
this->bar = std::make_shared<int>(bar);
}
std::string toString() const {
std::ostringstream ss;
if (bar) // bar was set
ss << *bar;
else // bar was never set
ss << "unset";
return ss.str();
}
};
Using this code
Foo f;
std::cout << f.toString() << std::endl;
f.setBar(42);
std::cout << f.toString() << std::endl;
produces the output
unset
42
I had been using this one-liner in the past, and after a bit of time away from Node.js had to try and rediscover it recently. Similar to the solution mentioned by @francoisrv, it utilizes the node_config_*
variables.
Create the following minimal package.json
file:
{
"name": "argument",
"version": "1.0.0",
"scripts": {
"argument": "echo \"The value of --foo is '${npm_config_foo}'\""
}
}
Run the following command:
npm run argument --foo=bar
Observe the following output:
The value of --foo is 'bar'
All of this is nicely documented in the npm official documentation:
Note: The Environment Variables heading explains that variables inside scripts do behave differently to what is defined in the documentation. This is true when it comes to case sensitivity, as well whether the argument is defined with a space or equals sign.
Note: If you are using an argument with hyphens, these will be replaced with underscores in the corresponding environment variable. For example, npm run example --foo-bar=baz
would correspond to ${npm_config_foo_bar}
.
Note: For non-WSL Windows users, see @Doctor Blue's comments below... TL;DR replace ${npm_config_foo}
with %npm_config_foo%
.
You can use css like below;

dom = etree.HTML(str(soup))
print dom.xpath('//*[@id="BGINP01_S1"]/section/div/font/text()')

ARIA stands for Accessible Rich Internet Applications.
WAI-ARIA is an incredibly powerful technology that allows developers to easily describe the purpose, state and other functionality of visually rich user interfaces - in a way that can be understood by Assistive Technology. WAI-ARIA has finally been integrated into the current working draft of the HTML 5 specification.
And if you are wondering what WAI-ARIA is, its the same thing.
Please note the terms WAI-ARIA and ARIA refer to the same thing. However, it is more correct to use WAI-ARIA to acknowledge its origins in WAI.
WAI = Web Accessibility Initiative
From the looks of it, ARIA is used for assistive technologies and mostly screen reading.
Most of your doubts will be cleared if you read this article
To add to craig_h's comment above (I currently don't have enough rep to add this as a comment to his answer, sorry), if your primary key is not an integer, you'll also want to tell your model what data type it is, by setting keyType at the top of the model definition.
public $keyType = 'string'
Eloquent understands any of the types defined in the castAttribute()
function, which as of Laravel 5.4 are: int, float, string, bool, object, array, collection, date and timestamp.
This will ensure that your primary key is correctly cast into the equivalent PHP data type.
Documentation can be found e.g. at MDN. Note that .split()
is not a jQuery method, but a native string method.
If you use .split()
on a string, then you get an array back with the substrings:
var str = 'something -- something_else';
var substr = str.split(' -- ');
// substr[0] contains "something"
// substr[1] contains "something_else"
If this value is in some field you could also do:
tRow.append($('<td>').text($('[id$=txtEntry2]').val().split(' -- ')[0])));

If each side of the rectangle is a line segment, and the user drawn portion is a line segment, then you need to just check the user drawn segment for intersection with the four side line segments. This should be a fairly simple exercise given the start and end points of each segment.
You have compiled your code with references to the correct math.h header file, but when you attempted to link it, you forgot the option to include the math library. As a result, you can compile your .o object files, but not build your executable.
As Paul has already mentioned add "-lm
" to link with the math library in the step where you are attempting to generate your executable.
Why for
sin()
in<math.h>
, do we need-lm
option explicitly; but, not forprintf()
in<stdio.h>
?
Because both these functions are implemented as part of the "Single UNIX Specification". This history of this standard is interesting, and is known by many names (IEEE Std 1003.1, X/Open Portability Guide, POSIX, Spec 1170).
This standard, specifically separates out the "Standard C library" routines from the "Standard C Mathematical Library" routines (page 277). The pertinent passage is copied below:
Standard C Library
The Standard C library is automatically searched by
cc
to resolve external references. This library supports all of the interfaces of the Base System, as defined in Volume 1, except for the Math Routines.Standard C Mathematical Library
This library supports the Base System math routines, as defined in Volume 1. The
cc
option-lm
is used to search this library.
The reasoning behind this separation was influenced by a number of factors:
The pressures that fed into the decision to put -lm
in a different library probably included, but are not limited to:
sin()
and putting it in a custom built library.In any case, it is now part of the standard to not be automatically included as part of the C language, and that's why you must add -lm
.
Here's a simple function. It generates a data frame and automatically uses the names of the vectors as values for the first column.
myfunc <- function(a, b, names = NULL) {
setNames(data.frame(c(rep(deparse(substitute(a)), length(a)),
rep(deparse(substitute(b)), length(b))), c(a, b)), names)
}
An example:
x <-c(1,2,3)
y <-c(100,200,300)
x_name <- "cond"
y_name <- "rating"
myfunc(x, y, c(x_name, y_name))
cond rating
1 x 1
2 x 2
3 x 3
4 y 100
5 y 200
6 y 300
The method I use is to import the ch.qos.logback modules and then type-cast the slf4j Logger instance to a ch.qos.logback.classic.Logger. This instance includes a setLevel() method.
import ch.qos.logback.classic.Level;
import ch.qos.logback.classic.Logger;
Logger levelSet = (Logger) LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME);
// Now you can set the desired logging-level
levelSet.setLevel( Level.OFF );
To find out the possible Logging-levels, you can explode the ch.qos.logback class to see all the possible values for Level:
prompt$ javap -cp logback-classic-1.2.3.jar ch.qos.logback.classic.Level
The results are the following:
{
// ...skipping
public static final ch.qos.logback.classic.Level OFF;
public static final ch.qos.logback.classic.Level ERROR;
public static final ch.qos.logback.classic.Level WARN;
public static final ch.qos.logback.classic.Level INFO;
public static final ch.qos.logback.classic.Level DEBUG;
public static final ch.qos.logback.classic.Level TRACE;
public static final ch.qos.logback.classic.Level ALL;
}
Let dictionary be :
dict={'key':['value1','value2']}
If you know the key :
print(len(dict[key]))
else :
val=[len(i) for i in dict.values()]
print(val[0])
# for printing length of 1st key value or length of values in keys if all keys have same amount of values.
You've an number of options, depending on how you want to play it:
isNaN(val)
Returns true if val is not a number, false if it is. In your case, this is probably what you need.
isFinite(val)
Returns true if val, when cast to a String, is a number and it is not equal to +/- Infinity
/^\d+$/.test(val)
Returns true if val, when cast to a String, has only digits (probably not what you need).
