For me, this error came up when I was trying to rollback a transaction block after encountering an exception, inside another transaction block.

All I had to do to fix it was to remove my inner transaction block.

Things can get quite messy when using nested transactions, best to avoid this and just restructure your code.

The default char is the character with an int value of 0 (zero).

char NULLCHAR = (char) 0;

char NULLCHAR = '\0';

This will end the function, and you can even customize the "Error" message:

import sys

def end():
    if condition:
        # the player wants to play again:
        main()
    elif not condition:
        sys.exit("The player doesn't want to play again") #Right here 

You could just add a few COUNTIF statements together:

=COUNTIF(A1:A196,"yes")+COUNTIF(A1:A196,"no")+COUNTIF(J1:J196,"agree")

This will give you the result you need.

EDIT

Sorry, misread the question. Nicholas is right that the above will double count. I wasn't thinking of the AND condition the right way. Here's an alternative that should give you the correct results, which you were pretty close to in the first place:

=SUM(COUNTIFS(A1:A196,{"yes","no"},J1:J196,"agree"))

Make a connection and open it.

con = new OracleConnection("Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=<database_name>)));User Id =<userid>; Password =<password>");
con.Open();

Write the select query:

string sql = "select * from Pending_Tasks";

Create a command object:

OracleCommand cmd = new OracleCommand(sql, con);

Execute the command and put the result in a object to read it.

OracleDataReader r = cmd.ExecuteReader();

now start reading from it.

Preliminary notes

This answer is an attempt to explain why Git behaves the way it does. It is not a recommendation to engage in any particular workflows. (My own preference is to just commit anyway, avoiding git stash and not trying to be too tricky, but others like other methods.)

The observation here is that, after you start working in branch1 (forgetting or not realizing that it would be good to switch to a different branch branch2 first), you run:

git checkout branch2

Sometimes Git says "OK, you're on branch2 now!" Sometimes, Git says "I can't do that, I'd lose some of your changes."

If Git won't let you do it, you have to commit your changes, to save them somewhere permanent. You may want to use git stash to save them; this is one of the things it's designed for. Note that git stash save or git stash push actually means "Commit all the changes, but on no branch at all, then remove them from where I am now." That makes it possible to switch: you now have no in-progress changes. You can then git stash apply them after switching.

Sidebar: git stash save is the old syntax; git stash push was introduced in Git version 2.13, to fix up some problems with the arguments to git stash and allow for new options. Both do the same thing, when used in the basic ways.

You can stop reading here, if you like!

If Git won't let you switch, you already have a remedy: use git stash or git commit; or, if your changes are trivial to re-create, use git checkout -f to force it. This answer is all about when Git will let you git checkout branch2 even though you started making some changes. Why does it work sometimes, and not other times?

The rule here is simple in one way, and complicated/hard-to-explain in another:

You may switch branches with uncommitted changes in the work-tree if and only if said switching does not require clobbering those changes.

That is—and please note that this is still simplified; there are some extra-difficult corner cases with staged git adds, git rms and such—suppose you are on branch1. A git checkout branch2 would have to do this:

• For every file that is in branch1 and not in branch2,¹ remove that file.
• For every file that is in branch2 and not in branch1, create that file (with appropriate contents).
• For every file that is in both branches, if the version in branch2 is different, update the working tree version.

Each of these steps could clobber something in your work-tree:

• Removing a file is "safe" if the version in the work-tree is the same as the committed version in branch1; it's "unsafe" if you've made changes.
• Creating a file the way it appears in branch2 is "safe" if it does not exist now.² It's "unsafe" if it does exist now but has the "wrong" contents.
• And of course, replacing the work-tree version of a file with a different version is "safe" if the work-tree version is already committed to branch1.

Creating a new branch (git checkout -b newbranch) is always considered "safe": no files will be added, removed, or altered in the work-tree as part of this process, and the index/staging-area is also untouched. (Caveat: it's safe when creating a new branch without changing the new branch's starting-point; but if you add another argument, e.g., git checkout -b newbranch different-start-point, this might have to change things, to move to different-start-point. Git will then apply the checkout safety rules as usual.)

¹This requires that we define what it means for a file to be in a branch, which in turn requires defining the word branch properly. (See also What exactly do we mean by "branch"?) Here, what I really mean is the commit to which the branch-name resolves: a file whose path is P is in branch1 if git rev-parse branch1:P produces a hash. That file is not in branch1 if you get an error message instead. The existence of path P in your index or work-tree is not relevant when answering this particular question. Thus, the secret here is to examine the result of git rev-parse on each branch-name:path. This either fails because the file is "in" at most one branch, or gives us two hash IDs. If the two hash IDs are the same, the file is the same in both branches. No changing is required. If the hash IDs differ, the file is different in the two branches, and must be changed to switch branches.

The key notion here is that files in commits are frozen forever. Files you will edit are obviously not frozen. We are, at least initially, looking only at the mismatches between two frozen commits. Unfortunately, we—or Git—also have to deal with files that aren't in the commit you're going to switch away from and are in the commit you're going to switch to. This leads to the remaining complications, since files can also exist in the index and/or in the work-tree, without having to exist these two particular frozen commits we're working with.

²It might be considered "sort-of-safe" if it already exists with the "right contents", so that Git does not have to create it after all. I recall at least some versions of Git allowing this, but testing just now shows it to be considered "unsafe" in Git 1.8.5.4. The same argument would apply to a modified file that happens to be modified to match the to-be-switch-to branch. Again, 1.8.5.4 just says "would be overwritten", though. See the end of the technical notes as well: my memory may be faulty as I don't think the read-tree rules have changed since I first started using Git at version 1.5.something.

Does it matter whether the changes are staged or unstaged?

Yes, in some ways. In particular, you can stage a change, then "de-modify" the work tree file. Here's a file in two branches, that's different in branch1 and branch2:

$ git show branch1:inboth
this file is in both branches
$ git show branch2:inboth
this file is in both branches
but it has more stuff in branch2 now
$ git checkout branch1
Switched to branch 'branch1'
$ echo 'but it has more stuff in branch2 now' >> inboth

At this point, the working tree file inboth matches the one in branch2, even though we're on branch1. This change is not staged for commit, which is what git status --short shows here:

$ git status --short
 M inboth

The space-then-M means "modified but not staged" (or more precisely, working-tree copy differs from staged/index copy).

$ git checkout branch2
error: Your local changes ...

OK, now let's stage the working-tree copy, which we already know also matches the copy in branch2.

$ git add inboth
$ git status --short
M  inboth
$ git checkout branch2
Switched to branch 'branch2'

Here the staged-and-working copies both matched what was in branch2, so the checkout was allowed.

Let's try another step:

$ git checkout branch1
Switched to branch 'branch1'
$ cat inboth
this file is in both branches

The change I made is lost from the staging area now (because checkout writes through the staging area). This is a bit of a corner case. The change is not gone, but the fact that I had staged it, is gone.

Let's stage a third variant of the file, different from either branch-copy, then set the working copy to match the current branch version:

$ echo 'staged version different from all' > inboth
$ git add inboth
$ git show branch1:inboth > inboth
$ git status --short
MM inboth

The two Ms here mean: staged file differs from HEAD file, and, working-tree file differs from staged file. The working-tree version does match the branch1 (aka HEAD) version:

$ git diff HEAD
$

But git checkout won't allow the checkout:

$ git checkout branch2
error: Your local changes ...

Let's set the branch2 version as the working version:

$ git show branch2:inboth > inboth
$ git status --short
MM inboth
$ git diff HEAD
diff --git a/inboth b/inboth
index ecb07f7..aee20fb 100644
--- a/inboth
+++ b/inboth
@@ -1 +1,2 @@
 this file is in both branches
+but it has more stuff in branch2 now
$ git diff branch2 -- inboth
$ git checkout branch2
error: Your local changes ...

Even though the current working copy matches the one in branch2, the staged file does not, so a git checkout would lose that copy, and the git checkout is rejected.

Technical notes—only for the insanely curious :-)

The underlying implementation mechanism for all of this is Git's index. The index, also called the "staging area", is where you build the next commit: it starts out matching the current commit, i.e., whatever you have checked-out now, and then each time you git add a file, you replace the index version with whatever you have in your work-tree.

Remember, the work-tree is where you work on your files. Here, they have their normal form, rather than some special only-useful-to-Git form like they do in commits and in the index. So you extract a file from a commit, through the index, and then on into the work-tree. After changing it, you git add it to the index. So there are in fact three places for each file: the current commit, the index, and the work-tree.

When you run git checkout branch2, what Git does underneath the covers is to compare the tip commit of branch2 to whatever is in both the current commit and the index now. Any file that matches what's there now, Git can leave alone. It's all untouched. Any file that's the same in both commits, Git can also leave alone—and these are the ones that let you switch branches.

Much of Git, including commit-switching, is relatively fast because of this index. What's actually in the index is not each file itself, but rather each file's hash. The copy of the file itself is stored as what Git calls a blob object, in the repository. This is similar to how the files are stored in commits as well: commits don't actually contain the files, they just lead Git to the hash ID of each file. So Git can compare hash IDs—currently 160-bit-long strings—to decide if commits X and Y have the same file or not. It can then compare those hash IDs to the hash ID in the index, too.

This is what leads to all the oddball corner cases above. We have commits X and Y that both have file path/to/name.txt, and we have an index entry for path/to/name.txt. Maybe all three hashes match. Maybe two of them match and one doesn't. Maybe all three are different. And, we might also have another/file.txt that's only in X or only in Y and is or is not in the index now. Each of these various cases requires its own separate consideration: does Git need to copy the file out from commit to index, or remove it from index, to switch from X to Y? If so, it also has to copy the file to the work-tree, or remove it from the work-tree. And if that's the case, the index and work-tree versions had better match at least one of the committed versions; otherwise Git will be clobbering some data.

(The complete rules for all of this are described in, not the git checkout documentation as you might expect, but rather the git read-tree documentation, under the section titled "Two Tree Merge".)

Try the following :

try
{
    var fromEmailAddress =  ConfigurationManager.AppSettings["FromEmailAddress"].ToString();
    var fromEmailDisplayName = ConfigurationManager.AppSettings["FromEmailDisplayName"].ToString();
    var fromEmailPassword = ConfigurationManager.AppSettings["FromEmailPassword"].ToString();
    var smtpHost = ConfigurationManager.AppSettings["SMTPHost"].ToString();
    var smtpPort = ConfigurationManager.AppSettings["SMTPPort"].ToString();

    string body = "Your registration has been done successfully. Thank you.";
    MailMessage message = new MailMessage(new MailAddress(fromEmailAddress, fromEmailDisplayName), new MailAddress(ud.LoginId, ud.FullName));
    message.Subject = "Thank You For Your Registration";
    message.IsBodyHtml = true;
    message.Body = body;

    var client = new SmtpClient();
    client.Credentials = new NetworkCredential(fromEmailAddress, fromEmailPassword);
    client.Host = smtpHost;
    client.EnableSsl = true;
    client.Port = !string.IsNullOrEmpty(smtpPort) ? Convert.ToInt32(smtpPort) : 0;
    client.Send(message);
}
catch (Exception ex)
{
    throw (new Exception("Mail send failed to loginId " + ud.LoginId + ", though registration done."));
}

And then in you web.config add the following in between

<!--Email Config-->
<add key="FromEmailAddress" value="sender emailaddress"/>
<add key="FromEmailDisplayName" value="Display Name"/>
<add key="FromEmailPassword" value="sender Password"/>
<add key="SMTPHost" value="smtp-proxy.tm.net.my"/>
<add key="SMTPPort" value="smptp Port"/>

Another possible solution which I think is more semantically correct is to change the floated inner elements to be 'display: inline'. This example and what I was working on when I came across this page both use floated divs in much exactly the same way that a span would be used. Instead of using divs, switch to span, or if you are using another element which is by default 'display: block' instead of 'display: inline' then change it to be 'display: inline'. I believe this is the 100% semantically correct solution.

Solution 1, floating the parent, is essentially to change the entire document to be floated.

Solution 2, setting an explicit height, is like drawing a box and saying I want to put a picture here, i.e. use this if you are doing an img tag.

Solution 3, adding a spacer to clear float, is like adding an extra line below your content and will mess with surrounding elements too. If you use this approach you probably want to set the div to be height: 0px.

Solution 4, overflow: auto, is acknowledging that you don't know how to lay out the document and you are admitting that you don't know what to do.

I work at Auth0 and I was involved in the design of the refresh token feature.

It all depends on the type of application and here is our recommended approach.

Web applications

A good pattern is to refresh the token before it expires.

Set the token expiration to one week and refresh the token every time the user opens the web application and every one hour. If a user doesn't open the application for more than a week, they will have to login again and this is acceptable web application UX.

To refresh the token, your API needs a new endpoint that receives a valid, not expired JWT and returns the same signed JWT with the new expiration field. Then the web application will store the token somewhere.

Mobile/Native applications

Most native applications do login once and only once.

The idea is that the refresh token never expires and it can be exchanged always for a valid JWT.

The problem with a token that never expires is that never means never. What do you do if you lose your phone? So, it needs to be identifiable by the user somehow and the application needs to provide a way to revoke access. We decided to use the device's name, e.g. "maryo's iPad". Then the user can go to the application and revoke access to "maryo's iPad".

Another approach is to revoke the refresh token on specific events. An interesting event is changing the password.

We believe that JWT is not useful for these use cases, so we use a random generated string and we store it on our side.

For those that are looking for a solution in Kotlin here is what worked for me:

private fun setupTermsAndConditions() {
    val termsAndConditions = resources.getString(R.string.terms_and_conditions)
    val spannableString = SpannableString(termsAndConditions)
    val clickableSpan = object : ClickableSpan() {
        override fun onClick(widget: View) {
            if (checkForWifiAndMobileInternet()) {
                // binding.viewModel!!.openTermsAndConditions()
                showToast("Good, open the link!!!")

            } else {
                showToast("Cannot open this file because of internet connection!")
            }

        }

        override fun updateDrawState(textPaint : TextPaint) {
            super.updateDrawState(textPaint)
            textPaint.color = resources.getColor(R.color.colorGrey)
            textPaint.isFakeBoldText = true
        }
    }

    spannableString.setSpan(clickableSpan, 34, 86, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
    binding.tvTermsAndConditions.text = spannableString
    binding.tvTermsAndConditions.movementMethod = LinkMovementMethod.getInstance()
    binding.tvTermsAndConditions.setHighlightColor(Color.TRANSPARENT);

}

rising_edge is defined as:

FUNCTION rising_edge  (SIGNAL s : std_ulogic) RETURN BOOLEAN IS
BEGIN
    RETURN (s'EVENT AND (To_X01(s) = '1') AND
                        (To_X01(s'LAST_VALUE) = '0'));
END;

FUNCTION To_X01  ( s : std_ulogic ) RETURN  X01 IS
BEGIN
    RETURN (cvt_to_x01(s));
END;

CONSTANT cvt_to_x01 : logic_x01_table := (
                     'X',  -- 'U'
                     'X',  -- 'X'
                     '0',  -- '0'
                     '1',  -- '1'
                     'X',  -- 'Z'
                     'X',  -- 'W'
                     '0',  -- 'L'
                     '1',  -- 'H'
                     'X'   -- '-'
                    );

If your clock only goes from 0 to 1, and from 1 to 0, then rising_edge will produce identical code. Otherwise, you can interpret the difference.

Personally, my clocks only go from 0 to 1 and vice versa. I find rising_edge(clk) to be more descriptive than the (clk'event and clk = '1') variant.

(DEMO)
Codes:

.backimage {width:99%;  height:98%;  position:absolute;    background:transparent url("http://upload.wikimedia.org/wikipedia/commons/4/41/Brickwall_texture.jpg") repeat scroll 0% 0%;  }

and

<div>
    <div class="backimage"></div>

</div>

Modify your log4j.properties file accordingly:

log4j.rootLogger=TRACE,stdout
...
log4j.logger.debugLog=TRACE,debugLog
log4j.logger.reportsLog=DEBUG,reportsLog

Change the log levels for each logger depending to your needs.

You can't load a controller from a controller in CI - unless you use HMVC or something.

You should think about your architecture a bit. If you need to call a controller method from another controller, then you should probably abstract that code out to a helper or library and call it from both controllers.

UPDATE

After reading your question again, I realize that your end goal is not necessarily HMVC, but URI manipulation. Correct me if I'm wrong, but it seems like you're trying to accomplish URLs with the first section being the method name and leave out the controller name altogether.

If this is the case, you'd get a cleaner solution by getting creative with your routes.

For a really basic example, say you have two controllers, controller1 and controller2. Controller1 has a method method_1 - and controller2 has a method method_2.

You can set up routes like this:

$route['method_1'] = "controller1/method_1";
$route['method_2'] = "controller2/method_2";

Then, you can call method 1 with a URL like http://site.com/method_1 and method 2 with http://site.com/method_2.

Albeit, this is a hard-coded, very basic, example - but it could get you to where you need to be if all you need to do is remove the controller from the URL.

You could also go with remapping your controllers.

From the docs: "If your controller contains a function named _remap(), it will always get called regardless of what your URI contains.":

public function _remap($method)
{
    if ($method == 'some_method')
    {
        $this->$method();
    }
    else
    {
        $this->default_method();
    }
}

Just for the reference, if you work in scripts (batch processing), not in stored procedure, flushing output is triggered by the GO command, e.g.

print 'test'
print 'test'
go

In general, my conclusion is following: output of mssql script execution, executing in SMS GUI or with sqlcmd.exe, is flushed to file, stdoutput, gui window on first GO statement or until the end of the script.

Flushing inside of stored procedure functions differently, since you can not place GO inside.

starting from the chad's answer, here is the COMPLETE working solution to parse UML, with propper handling of comments, with just 2 little functions (more than 2 bu you can mix them all). I don't say chad's one didn't work at all, but it had too much issues with badly formated XML files: So you have to be a bit more tricky to handle comments and misplaced spaces/CR/TAB/etc.

The purpose of this answer is to give ready-2-use, out of the box bash functions to anyone needing parsing UML without complex tools using perl, python or anything else. As for me, I cannot install cpan, nor perl modules for the old production OS i'm working on, and python isn't available.

First, a definition of the UML words used in this post:

<!-- comment... -->
<tag attribute="value">content...</tag>

• Websphere xml (xmi and xmlns attributes)
• must have a compatible terminal with 256 colors
• 24 shades of grey
• compatibility added for IBM AIX bash 3.2.16(1)

The functions, first is the xml_read_dom which's called recursively by xml_read:

xml_read_dom() {

How to load all that stuff:

Either you know how to create functions and load them via FPATH (ksh) or an emulation of FPATH (bash)

If not, just copy/paste everything on the command line.

How does it work:

xml_read [-cdlp] [-x command <-a attribute>] <file.xml> [tag | "any"] [attributes .. | "content"]
  -c = NOCOLOR
  -d = Debug
  -l = LIGHT (no \"attribute=\" printed)
  -p = FORCE PRINT (when no attributes given)
  -x = apply a command on an attribute and print the result instead of the former value, in green color
  (no attribute given will load their values into your shell as $ATTRIBUTE=value; use '-p' to print them as well)

xml_read server.xml title content     # print content between <title></title>
xml_read server.xml Connector port    # print all port values from Connector tags
xml_read server.xml any port          # print all port values from any tags

With Debug mode (-d) comments and parsed attributes are printed to stderr

I could see the style by following below steps suggested by Babiker - "Right-click element, but DON'T move your mouse pointer away from the element, keep it in hover state. Choose inspect element via keyboard, as in hit up arrow and then Enter key."

For changing style follow above steps and then - Change your browser tab by pressing ctrl + TAB on the keyboard. Then click back on the tab you want to debug. Your hover screen will still be there. Now carefully take your mouse to developer tool area.

You could build your form using FormBuilder as it let you more flexible way to configure form.

export class MyComp {
  form: ControlGroup;

  constructor(@Inject()fb: FormBuilder) {  
    this.form = fb.group({  
      foo: ['', MyValidators.regex(/^(?!\s|.*\s$).*$/)]  
    });  
  }

Then in your template :

<input type="text" ngControl="foo" />
<div *ngIf="!form.foo.valid">Please correct foo entry !</div> 

You can also customize ng-invalid CSS class.

As there is actually no validators for regex, you have to write your own. It is a simple function that takes a control in input, and return null if valid or a StringMap if invalid.

export class MyValidators {
  static regex(pattern: string): Function {
    return (control: Control): {[key: string]: any} => {
      return control.value.match(pattern) ? null : {pattern: true};
    };
  }
}

Hope that it help you.

You can use Collections.min and List.indexOf:

int minIndex = list.indexOf(Collections.min(list));

If you want to traverse the list only once (the above may traverse it twice):

public static <T extends Comparable<T>> int findMinIndex(final List<T> xs) {
    int minIndex;
    if (xs.isEmpty()) {
        minIndex = -1;
    } else {
        final ListIterator<T> itr = xs.listIterator();
        T min = itr.next(); // first element as the current minimum
        minIndex = itr.previousIndex();
        while (itr.hasNext()) {
            final T curr = itr.next();
            if (curr.compareTo(min) < 0) {
                min = curr;
                minIndex = itr.previousIndex();
            }
        }
    }
    return minIndex;
}

Try it:

String command = "killall <your_proccess>";
Process p = Runtime.getRuntime().exec(command);
p.destroy();

if the process is still alive, add:

p.destroyForcibly();

If you're running your PHP script from the command-line, passthru() has one large benefit. It will let you execute scripts/programs such as vim, dialog, etc, letting those programs handle control and returning to your script only when they are done.

If you use system() or exec() to execute those scripts/programs, it simply won't work.

Gotcha: For some reason, you can't execute less with passthru() in PHP.

Packages are just .xar archives with a different extension and a specified file hierarchy. Unfortunately, part of that file hierarchy is a cpio.gz archive of the actual installables, and usually that's what you want to edit. And there's also a Bom file that includes information on the files inside that cpio archive, and a PackageInfo file that includes summary information.

If you really do just need to edit one of the info files, that's simple:

mkdir Foo
cd Foo
xar -xf ../Foo.pkg
# edit stuff
xar -cf ../Foo-new.pkg *

But if you need to edit the installable files:

mkdir Foo
cd Foo
xar -xf ../Foo.pkg
cd foo.pkg
cat Payload | gunzip -dc |cpio -i
# edit Foo.app/*
rm Payload
find ./Foo.app | cpio -o | gzip -c > Payload
mkbom Foo.app Bom # or edit Bom
# edit PackageInfo
rm -rf Foo.app
cd ..
xar -cf ../Foo-new.pkg

I believe you can get mkbom (and lsbom) for most linux distros. (If you can get ditto, that makes things even easier, but I'm not sure if that's nearly as ubiquitously available.)

For situation, when "piping" is necessary you can use :

|&

For example:

echo -ne "15\n100\n"|sort -c |& tee >sort_result.txt

or

TIMEFORMAT=%R;for i in `seq 1 20` ; do time kubectl get pods |grep node >>js.log  ; done |& sort -h

This bash-based solutions can pipe STDOUT and STDERR separately (from STDERR of "sort -c" or from STDERR to "sort -h").

Once you've done this

group p by p.SomeId into pg  

you no longer have access to the range variables used in the initial from. That is, you can no longer talk about p or bp, you can only talk about pg.

Now, pg is a group and so contains more than one product. All the products in a given pg group have the same SomeId (since that's what you grouped by), but I don't know if that means they all have the same BaseProductId.

To get a base product name, you have to pick a particular product in the pg group (As you are doing with SomeId and CountryCode), and then join to BaseProducts.

var result = from p in Products                         
 group p by p.SomeId into pg                         
 // join *after* group
 join bp in BaseProducts on pg.FirstOrDefault().BaseProductId equals bp.Id         
 select new ProductPriceMinMax { 
       SomeId = pg.FirstOrDefault().SomeId, 
       CountryCode = pg.FirstOrDefault().CountryCode, 
       MinPrice = pg.Min(m => m.Price), 
       MaxPrice = pg.Max(m => m.Price),
       BaseProductName = bp.Name  // now there is a 'bp' in scope
 };

That said, this looks pretty unusual and I think you should step back and consider what you are actually trying to retrieve.

What database are you using? normally you don't save files to a database but i think sql 2008 has support for it...

A file is binary data hence UTF 8 does not matter here..

UTF 8 matters when you try to convert a string to a byte array... not a file to byte array.

For future Googlers i've a different approach to check if it's last element. It's similar to last lines in OP question.

This directly compares elements rather than just checking index numbers.

$yourset.each(function() {
    var $this = $(this);
    if($this[0] === $yourset.last()[0]) {
        //$this is the last one
    }
});

A more language-independent choice for string literals is the international standard ISO 8601 format "YYYY-MM-DDThh:mm:ss". I used the SQL query below to test the format, and it does indeed work in all SQL languages in sys.syslanguages:

declare @sql nvarchar(4000)

declare @LangID smallint
declare @Alias sysname

declare @MaxLangID smallint
select @MaxLangID = max(langid) from sys.syslanguages

set @LangID = 0

while @LangID <= @MaxLangID
begin

    select @Alias = alias
    from sys.syslanguages
    where langid = @LangID

    if @Alias is not null
    begin

        begin try
            set @sql = N'declare @TestLang table (langdate datetime)
    set language ''' + @alias + N''';
    insert into @TestLang (langdate)
    values (''2012-06-18T10:34:09'')'
            print 'Testing ' + @Alias

            exec sp_executesql @sql
        end try
        begin catch
            print 'Error in language ' + @Alias
            print ERROR_MESSAGE()
        end catch
    end

    select @LangID = min(langid)
    from sys.syslanguages
    where langid > @LangID
end

According to the String Literal Date and Time Formats section in Microsoft TechNet, the standard ANSI Standard SQL date format "YYYY-MM-DD hh:mm:ss" is supposed to be "multi-language". However, using the same query, the ANSI format does not work in all SQL languages.

For example, in Danish, you will many errors like the following:

Error in language Danish The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.

If you want to build a query in C# to run on SQL Server, and you need to pass a date in the ISO 8601 format, use the Sortable "s" format specifier:

string.Format("select convert(datetime2, '{0:s}'", DateTime.Now);

import android.support.v7.widget.RecyclerView;

In Android Studio, importing is not as intuitive as one would hope. Try importing this bit and see how it helps!

I would avoid inline javascript altogether, and as I mentioned in my comment, I'd also probably use <input type="button" /> for this. That being said...

If you are using Bootstrap 4, you can simple use a color utility class (e.g. text-success, text-danger, etc... ).

You can also create your own classes (e.g. text-my-own-color)

Both options are shown in the example below, run the code snippet to see a live demo.

.text-my-own-color {
  color: #663300 !important; // Define your own color in your CSS
}
.text-my-own-color:hover, .text-my-own-color:active {
  color: #664D33 !important; // Define your own color's darkening/lightening in your CSS
}

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet" />
<div class="navbar-collapse">
  <ul class="nav pull-right">

    <!-- Bootstrap's color utility class -->
    <li class="active"><a class="text-success" href="#">? ???</a></li>

    <!-- Bootstrap's color utility class -->
    <li><a class="text-danger" href="#">??? ??? ????????</a></li>

    <!-- Bootstrap's color utility class -->
    <li><a class="text-warning" href="#">????</a></li>

    <!-- Custom color utility class -->
    <li><a class="text-my-own-color" href="#">????????</a></li>

  </ul>
</div>

With sed it is possible to do something like this with a string:

echo "$STRING" | sed -e "s|.*AAA\(.*\)ZZZ.*|\1|"

And this will give me 1234 as a result.

You could do the same with re.sub function using the same regex.

>>> re.sub(r'.*AAA(.*)ZZZ.*', r'\1', 'gfgfdAAA1234ZZZuijjk')
'1234'

In basic sed, capturing group are represented by \(..\), but in python it was represented by (..).

Set LDFLAGS and CFLAGS when you run make:

$ LDFLAGS="-L/home/me/local/lib" CFLAGS="-I/home/me/local/include" make

If you don't want to do that a gazillion times, export these in your .bashrc (or your shell equivalent). Also set LD_LIBRARY_PATH to include /home/me/local/lib:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/me/local/lib

jarsigner can use your pfx file as the keystore for signing your jar. Be sure that your pfx file has the private key and the cert chain when you export it. There is no need to convert to other formats. The trick is to obtain the Alias of your pfx file:

 keytool -list -storetype pkcs12 -keystore your_pfx_file -v | grep Alias

Once you have your alias, signing is easy

jarsigner.exe -storetype pkcs12 -keystore pfx_file jar_file "your alias"

The above two commands will prompt you for the password you specified at pfx export. If you want to have your password hang out in clear text use the -storepass switch before the -keystore switch

Once signed, admire your work:

jarsigner.exe -verify -verbose -certs  yourjarfile

You have $headers .= '...'; followed by $headers = '...';; the second line is overwriting the first.

Just put the $headers .= "Bcc: $emailList\r\n"; say after the Content-type line and it should be fine.

On a side note, the To is generally required; mail servers might mark your message as spam otherwise.

$headers  = "From: [email protected]\r\n" .
  "X-Mailer: php\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$headers .= "Bcc: $emailList\r\n";

just write it yourself using simple recursion:

public List<File> addFiles(List<File> files, File dir)
{
    if (files == null)
        files = new LinkedList<File>();

    if (!dir.isDirectory())
    {
        files.add(dir);
        return files;
    }

    for (File file : dir.listFiles())
        addFiles(files, file);
    return files;
}

JSONObject json = new JSONObject();
json.put("fromZIPCode","123456"); 

JSONObject json1 = new JSONObject();
json1.put("fromZIPCode","123456"); 
       sList.add(json1);
       sList.add(json);

System.out.println(sList);

Output will be

[{"fromZIPCode":"123456"},{"fromZIPCode":"123456"}]

You can use the EXACT Function for exact string comparisons.

Using .one ensures this is done only once and not repeatedly.

$(window).one("focus", function() {
    localStorage.clear();
});

It is okay to put several document.ready event listeners (if you need other events to execute multiple times) as long as you do not overdo it, for the sake of readability.

.one is especially useful when you want local storage to be cleared only once the first time a web page is opened or when a mobile application is installed the first time.

   // Fired once when document is ready
   $(document).one('ready', function () {
       localStorage.clear();
   });

Really quick and really dirty? This one-liner on the top of your script will work:

[[ $(pgrep -c "`basename \"$0\"`") -gt 1 ]] && exit

Of course, just make sure that your script name is unique. :)

Use the --force (-f) flag on your mysql import. Rather than stopping on the offending statement, MySQL will continue and just log the errors to the console.

For example:

mysql -u userName -p -f -D dbName < script.sql

At regular intervals, I am adding new lines of text to it. I would like the textbox to automatically scroll to the bottom-most entry (the newest one) whenever a new line is added.

If you use TextBox.AppendText(string text), it will automatically scroll to the end of the newly appended text. It avoids the flickering scrollbar if you're calling it in a loop.

It also happens to be an order of magnitude faster than concatenating onto the .Text property. Though that might depend on how often you're calling it; I was testing with a tight loop.

This will not scroll if it is called before the textbox is shown, or if the textbox is otherwise not visible (e.g. in a different tab of a TabPanel). See TextBox.AppendText() not autoscrolling. This may or may not be important, depending on if you require autoscroll when the user can't see the textbox.

It seems that the alternative method from the other answers also don't work in this case. One way around it is to perform additional scrolling on the VisibleChanged event:

textBox.VisibleChanged += (sender, e) =>
{
    if (textBox.Visible)
    {
        textBox.SelectionStart = textBox.TextLength;
        textBox.ScrollToCaret();
    }
};

Internally, AppendText does something like this:

textBox.Select(textBox.TextLength + 1, 0);
textBox.SelectedText = textToAppend;

But there should be no reason to do it manually.

^{(If you decompile it yourself, you'll see that it uses some possibly more efficient internal methods, and has what seems to be a minor special case.)}

So basically Integrated Security=SSPI; is preferred since works with both SQLClient & OleDB provider.

Here's the full set of syntaxes according to MSDN - Connection String Syntax (ADO.NET)

// http://en.wikipedia.org/wiki/Julian_day
public static int julianDay(int year, int month, int day) {
  int a = (14 - month) / 12;
  int y = year + 4800 - a;
  int m = month + 12 * a - 3;
  int jdn = day + (153 * m + 2)/5 + 365*y + y/4 - y/100 + y/400 - 32045;
  return jdn;
}

public static int diff(int y1, int m1, int d1, int y2, int m2, int d2) {
  return julianDay(y1, m1, d1) - julianDay(y2, m2, d2);
}

I tried this command to display the list of files in the directory.

dir /s /b > List.txt

In the file it displays the list below.

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Logitech\LogiUCPluginForCisco\lucpcisco.dll

What is want to do is only to display sub-directory not the full directory path.

Just like this:

N-tier data applications are data applications that are separated into multiple tiers. Also called "distributed applications" and "multitier applications," n-tier applications separate processing into discrete tiers that are distributed between the client and the server. When you develop applications that access data, you should have a clear separation between the various tiers that make up the application.

A typical n-tier application includes a presentation tier, a middle tier, and a data tier. The easiest way to separate the various tiers in an n-tier application is to create discrete projects for each tier that you want to include in your application. For example, the presentation tier might be a Windows Forms application, whereas the data access logic might be a class library located in the middle tier. Additionally, the presentation layer might communicate with the data access logic in the middle tier through a service such as a service. Separating application components into separate tiers increases the maintainability and scalability of the application. It does this by enabling easier adoption of new technologies that can be applied to a single tier without the requirement to redesign the whole solution. In addition, n-tier applications typically store sensitive information in the middle-tier, which maintains isolation from the presentation tier.

@ pass only strings

Your strings are JSON formatted, so you will need to parse it into a object. For that you can use JSON.NET.

Here is an example on how to parse a JSON string into a dynamic object:

string source = "{\r\n   \"id\": \"100000280905615\", \r\n \"name\": \"Jerard Jones\",  \r\n   \"first_name\": \"Jerard\", \r\n   \"last_name\": \"Jones\", \r\n   \"link\": \"https://www.facebook.com/Jerard.Jones\", \r\n   \"username\": \"Jerard.Jones\", \r\n   \"gender\": \"female\", \r\n   \"locale\": \"en_US\"\r\n}";
dynamic data = JObject.Parse(source);
Console.WriteLine(data.id);
Console.WriteLine(data.first_name);
Console.WriteLine(data.last_name);
Console.WriteLine(data.gender);
Console.WriteLine(data.locale);

Happy coding!

To exit from an Android app, just simply use. in your Main Activity, or you can use Android manifest file to set

android:noHistory="true"

As said by Faiyaz, to get default backup location for the instance, you cannot get it into msdb, but you have to look into Registry. You can get it in T-SQL in using xp_instance_regread stored procedure like this:

EXEC  master.dbo.xp_instance_regread 
      N'HKEY_LOCAL_MACHINE', N'SOFTWARE\Microsoft\\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQLServer',N'BackupDirectory'

The double backslash (\\) is because the spaces into that key name part (Microsoft SQL Server). The "MSSQL12.MSSQLSERVER" part is for default instance name for SQL 2014. You have to adapt to put your own instance name (look into Registry).

If I understood correctly, I would change the HTML to something like this:

<div id="shop">
    <div class="content">
        <img src="http://placehold.it/182x121"/> 
        <a href="#">Counter-Strike 1.6 Steam</a>
    </div>
</div>

Then I would be able to use position:absolute and position:relative to force the blue button down.

I have created a jsfiddle: http://jsfiddle.net/y9w99/

If you use rs.next() you will move the cursor, than you should to move first() why don't check using first() directly?

    public void fetchData(ResultSet res, JTable table) throws SQLException{     
    ResultSetMetaData metaData = res.getMetaData();
    int fieldsCount = metaData.getColumnCount();
    for (int i = 1; i <= fieldsCount; i++)
        ((DefaultTableModel) table.getModel()).addColumn(metaData.getColumnLabel(i));
    if (!res.first())
        JOptionPane.showMessageDialog(rootPane, "no data!");
    else
        do {
            Vector<Object> v = new Vector<Object>();
            for (int i = 1; i <= fieldsCount; i++)              
                v.addElement(res.getObject(i));         
            ((DefaultTableModel) table.getModel()).addRow(v);
        } while (res.next());
        res.close();
}

The reason you separate the login and non-login shell is because the .bashrc file is reloaded every time you start a new copy of Bash. The .profile file is loaded only when you either log in or use the appropriate flag to tell Bash to act as a login shell.

Personally,

• I put my PATH setup into a .profile file (because I sometimes use other shells);
• I put my Bash aliases and functions into my .bashrc file;

• I put this

  #!/bin/bash
  #
  # CRM .bash_profile Time-stamp: "2008-12-07 19:42"
  #
  # echo "Loading ${HOME}/.bash_profile"
  source ~/.profile # get my PATH setup
  source ~/.bashrc  # get my Bash aliases
  

  in my .bash_profile file.

Oh, and the reason you need to type bash again to get the new alias is that Bash loads your .bashrc file when it starts but it doesn't reload it unless you tell it to. You can reload the .bashrc file (and not need a second shell) by typing

source ~/.bashrc

which loads the .bashrc file as if you had typed the commands directly to Bash.

In PHP an array is an array; there is no primitive vs. object consideration, so there is no comparable optimization to be had.

That's the job that GNU's automake/autoconf are designed to solve. You might want to investigate them.

Alternatively you can set environment variables on your different platforms and make you Makefile conditional against them.

Here's the final solution for the case in update section (with the help of Google Collections):

Collections2.transform (fooCollection, new Function<Foo, Bar>() {
    public Bar apply (Foo foo) {
        return new Bar (foo);
    }
}).toArray (new Bar[fooCollection.size()]);

But, the key approach here was mentioned in the doublep's answer (I forgot for toArray method).

DateAndTime Reformat:

SELECT *, to_char( last_update, 'DD-MON-YYYY') as re_format from actor;

DEMO:

Append a semicolon to the following line to fix the issue.

font-family:    Arial, Helvetica, sans-serif;

First of all, never use a for in loop to enumerate over an array. Never. Use good old for(var i = 0; i<arr.length; i++).

The reason behind this is the following: each object in JavaScript has a special field called prototype. Everything you add to that field is going to be accessible on every object of that type. Suppose you want all arrays to have a cool new function called filter_0 that will filter zeroes out.

Array.prototype.filter_0 = function() {
    var res = [];
    for (var i = 0; i < this.length; i++) {
        if (this[i] != 0) {
            res.push(this[i]);
        }
    }
    return res;
};

console.log([0, 5, 0, 3, 0, 1, 0].filter_0());
//prints [5,3,1]

This is a standard way to extend objects and add new methods. Lots of libraries do this. However, let's look at how for in works now:

var listeners = ["a", "b", "c"];
for (o in listeners) {
    console.log(o);
}
//prints:
//  0
//  1
//  2
//  filter_0

Do you see? It suddenly thinks filter_0 is another array index. Of course, it is not really a numeric index, but for in enumerates through object fields, not just numeric indexes. So we're now enumerating through every numeric index and filter_0. But filter_0 is not a field of any particular array object, every array object has this property now.

Luckily, all objects have a hasOwnProperty method, which checks if this field really belongs to the object itself or if it is simply inherited from the prototype chain and thus belongs to all the objects of that type.

for (o in listeners) {
    if (listeners.hasOwnProperty(o)) {
       console.log(o);
    }
}
 //prints:
 //  0
 //  1
 //  2

Note, that although this code works as expected for arrays, you should never, never, use for in and for each in for arrays. Remember that for in enumerates the fields of an object, not array indexes or values.

var listeners = ["a", "b", "c"];
listeners.happy = "Happy debugging";

for (o in listeners) {
    if (listeners.hasOwnProperty(o)) {
       console.log(o);
    }
}

 //prints:
 //  0
 //  1
 //  2
 //  happy

<style type="text/css">
 .topcorner{
  position:absolute;
  top:10;
  right:15;
  }
</style>

You ca also use this in CSS external file.

If you're looking for the class-level equivalent of @property, then the answer is "there's no such thing". But remember, @property is only syntactic sugar, anyway; it just creates appropriately-named object methods.

You want to create class methods that access static variables which, as others have said, have only a slightly different syntax.

Here are the steps I used to manually install python3 for anyone else who wants to do it as it's not super straight forward. EDIT: It's almost certainly easier to use the yum package manager (see other answers).

Note, you'll probably want to do sudo yum groupinstall 'Development Tools' before doing this otherwise pip won't install.

wget https://www.python.org/ftp/python/3.4.2/Python-3.4.2.tgz
tar zxvf Python-3.4.2.tgz
cd Python-3.4.2
sudo yum install gcc
./configure --prefix=/opt/python3
make
sudo yum install openssl-devel
sudo make install
sudo ln -s /opt/python3/bin/python3 /usr/bin/python3
python3 (should start the interpreter if it's worked (quit() to exit)

You should add parse_dates=True, or parse_dates=['column name'] when reading, thats usually enough to magically parse it. But there are always weird formats which need to be defined manually. In such a case you can also add a date parser function, which is the most flexible way possible.

Suppose you have a column 'datetime' with your string, then:

from datetime import datetime
dateparse = lambda x: datetime.strptime(x, '%Y-%m-%d %H:%M:%S')

df = pd.read_csv(infile, parse_dates=['datetime'], date_parser=dateparse)

This way you can even combine multiple columns into a single datetime column, this merges a 'date' and a 'time' column into a single 'datetime' column:

dateparse = lambda x: datetime.strptime(x, '%Y-%m-%d %H:%M:%S')

df = pd.read_csv(infile, parse_dates={'datetime': ['date', 'time']}, date_parser=dateparse)

You can find directives (i.e. the letters to be used for different formats) for strptime and strftime in this page.

This is what I implemented without using pipe.

component.html

<div *ngFor="let item of filter(itemsList)">

component.ts

@Component({
....
})
export class YourComponent {
  filter(itemList: yourItemType[]): yourItemType[] {
    let result: yourItemType[] = [];
    //your filter logic here
    ...
    ...
    return result;
  }
}

How was the database exported?

• If it was exported using exp and a full schema was exported, then

  1. Create the user:

     create user <username> identified by <password> default tablespace <tablespacename> quota unlimited on <tablespacename>;
     

  2. Grant the rights:

     grant connect, create session, imp_full_database to <username>;
     

  3. Start the import with imp:

     imp <username>/<password>@<hostname> file=<filename>.dmp log=<filename>.log full=y;
     

• If it was exported using expdp, then start the import with impdp:

  impdp <username>/<password> directory=<directoryname> dumpfile=<filename>.dmp logfile=<filename>.log full=y;
  

Looking at the error log, it seems you have not specified the directory, so Oracle tries to find the dmp file in the default directory (i.e., E:\app\Vensi\admin\oratest\dpdump\).

Either move the export file to the above path or create a directory object to pointing to the path where the dmp file is present and pass the object name to the impdp command above.

Are you getting errors, or just not sure where to start?

%pylab inline

If you want to modify the original array instead of returning a new array, use .push()...

array1.push.apply(array1, array2);
array1.push.apply(array1, array3);

I used .apply to push the individual members of arrays 2 and 3 at once.

or...

array1.push.apply(array1, array2.concat(array3));

To deal with large arrays, you can do this in batches.

for (var n = 0, to_add = array2.concat(array3); n < to_add.length; n+=300) {
    array1.push.apply(array1, to_add.slice(n, n+300));
}

If you do this a lot, create a method or function to handle it.

var push_apply = Function.apply.bind([].push);
var slice_call = Function.call.bind([].slice);

Object.defineProperty(Array.prototype, "pushArrayMembers", {
    value: function() {
        for (var i = 0; i < arguments.length; i++) {
            var to_add = arguments[i];
            for (var n = 0; n < to_add.length; n+=300) {
                push_apply(this, slice_call(to_add, n, n+300));
            }
        }
    }
});

and use it like this:

array1.pushArrayMembers(array2, array3);

var push_apply = Function.apply.bind([].push);_x000D_
var slice_call = Function.call.bind([].slice);_x000D_
_x000D_
Object.defineProperty(Array.prototype, "pushArrayMembers", {_x000D_
    value: function() {_x000D_
        for (var i = 0; i < arguments.length; i++) {_x000D_
            var to_add = arguments[i];_x000D_
            for (var n = 0; n < to_add.length; n+=300) {_x000D_
                push_apply(this, slice_call(to_add, n, n+300));_x000D_
            }_x000D_
        }_x000D_
    }_x000D_
});_x000D_
_x000D_
var array1 = ['a','b','c'];_x000D_
var array2 = ['d','e','f'];_x000D_
var array3 = ['g','h','i'];_x000D_
_x000D_
array1.pushArrayMembers(array2, array3);_x000D_
_x000D_
document.body.textContent = JSON.stringify(array1, null, 4);

For ad hoc queries, the ODBC Test utility is pretty handy. Its design and interface is more oriented toward testing various parts of the ODBC API. But it works quite nicely for running queries and showing the output. It is part of the Microsoft Data Access Components.

To run a query, you can click the connect button (or use ctrl-F), choose a data source, type a query, then ctrl-E to execute it and ctrl-R to display the results (e.g., if it is a SELECT or something that returns a cursor).

I also faced the same issues and it was resolved when i created file named with DockerFile and mentioned all the command which wanted to get executed while creation of any image.

use json library

import json
json.dumps(list)

by the way, you might consider changing variable list to another name, list is the builtin function for a list creation, you may get some unexpected behaviours or some buggy code if you don't change the variable name.

Ctrl+Shift+D, but you have to put focus on the script output panel first...which you can do via the KB.

Run script.

Alt+PgDn     -  puts you in Script Output panel.
Ctrl+Shift+D -  clears panel.
Alt+PgUp     -  puts you back in editor panel. 

You can use java.util.Arrays:

String res = Arrays.toString(array);
System.out.println(res);

Output:

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

You need to use reflection to get the method to start with, then "construct" it by supplying type arguments with MakeGenericMethod:

MethodInfo method = typeof(Sample).GetMethod(nameof(Sample.GenericMethod));
MethodInfo generic = method.MakeGenericMethod(myType);
generic.Invoke(this, null);

For a static method, pass null as the first argument to Invoke. That's nothing to do with generic methods - it's just normal reflection.

As noted, a lot of this is simpler as of C# 4 using dynamic - if you can use type inference, of course. It doesn't help in cases where type inference isn't available, such as the exact example in the question.

 $tomorrow = date("Y-m-d", strtotime('tomorrow'));

or

  $tomorrow = date("Y-m-d", strtotime("+1 day"));

Tests

On the Tests class we will add an @XmlRootElement annotation. Doing this will let your JAXB implementation know that when a document starts with this element that it should instantiate this class. JAXB is configuration by exception, this means you only need to add annotations where your mapping differs from the default. Since the testData property differs from the default mapping we will use the @XmlElement annotation. You may find the following tutorial helpful: http://wiki.eclipse.org/EclipseLink/Examples/MOXy/GettingStarted

package forum11221136;

import javax.xml.bind.annotation.*;

@XmlRootElement
public class Tests {

    TestData testData;

    @XmlElement(name="test-data")
    public TestData getTestData() {
        return testData;
    }

    public void setTestData(TestData testData) {
        this.testData = testData;
    }

}

TestData

On this class I used the @XmlType annotation to specify the order in which the elements should be ordered in. I added a testData property that appeared to be missing. I also used an @XmlElement annotation for the same reason as in the Tests class.

package forum11221136;

import java.util.List;
import javax.xml.bind.annotation.*;

@XmlType(propOrder={"title", "book", "count", "testData"})
public class TestData {
    String title;
    String book;
    String count;
    List<TestData> testData;

    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public String getBook() {
        return book;
    }
    public void setBook(String book) {
        this.book = book;
    }
    public String getCount() {
        return count;
    }
    public void setCount(String count) {
        this.count = count;
    }
    @XmlElement(name="test-data")
    public List<TestData> getTestData() {
        return testData;
    }
    public void setTestData(List<TestData> testData) {
        this.testData = testData;
    }
}

Demo

Below is an example of how to use the JAXB APIs to read (unmarshal) the XML and populate your domain model and then write (marshal) the result back to XML.

package forum11221136;

import java.io.File;
import javax.xml.bind.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Tests.class);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        File xml = new File("src/forum11221136/input.xml");
        Tests tests = (Tests) unmarshaller.unmarshal(xml);

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(tests, System.out);
    }

}

Ok after having sunk way to much time into this problem this is the way I managed to get the appearance I was hoping for. I'm making it a separate answer so I can get everything in one place.

It's a combination of factors.

Firstly, don't try to get the toolbars to play nice through just themes. It seems to be impossible.

So apply themes explicitly to your Toolbars like in oRRs answer

layout/toolbar.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_alignParentTop="true"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    app:theme="@style/Dark.Overlay"
    app:popupTheme="@style/Dark.Overlay.LightPopup" />

However this is the magic sauce. In order to actually get the background colors I was hoping for you have to override the background attribute in your Toolbar themes

values/styles.xml:

<!-- 
    I expected android:colorBackground to be what I was looking for but
    it seems you have to override android:background
-->
<style name="Dark.Overlay" parent="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="android:background">?attr/colorPrimary</item>
</style>

<style name="Dark.Overlay.LightPopup" parent="ThemeOverlay.AppCompat.Light">
    <item name="android:background">@color/material_grey_200</item>
</style>

then just include your toolbar layout in your other layouts

<include android:id="@+id/mytoolbar" layout="@layout/toolbar" />

and you're good to go.

Hope this helps someone else so you don't have to spend as much time on this as I have.

(if anyone can figure out how to make this work using just themes, ie not having to apply the themes explicitly in the layout files I'll gladly support their answer instead)

EDIT:

So apparently posting a more complete answer was a downvote magnet so I'll just accept the imcomplete answer above but leave this answer here in case someone actually needs it. Feel free to keep downvoting if it makes you happy though.

For large datasets, how about JQuery UI Autocomplete, which is basically the "official" version of Jorn Zaeferrer's Autocomplete plugin?

I also wrote a straight JQuery combobox plugin that's gotten pretty good feedback from its users. It's explicitly not meant for large datasets though; I figure that if you want something that prunes the list based on what the user types, you're better off with Jorn's autocompletion plugin.

The key difference is that tuples are immutable. This means that you cannot change the values in a tuple once you have created it.

So if you're going to need to change the values use a List.

Benefits to tuples:

1. Slight performance improvement.
2. As a tuple is immutable it can be used as a key in a dictionary.
3. If you can't change it neither can anyone else, which is to say you don't need to worry about any API functions etc. changing your tuple without being asked.

but what's the deal with new lines and carriage returns? What's the difference? Is \n\n the equivalent of \r\r or \n\r? Which should I use when I'm creating a line gap between lines?

No one here seemed to actualy answer this question, so here I am.

\r represents 'carriage-return'

\n represents 'line-feed'

The actual reason for them goes back to typewriters. As you typed the 'carriage' would slowly slide, character by character, to the right of the typewriter. When you got to the end of the line you would return the carriage and then go to a new line. To go to the new line, you would flip a lever which fed the lines to the type writer. Thus these actions, combined, were called carriage return line feed. So quite literally:

A line feed,\n, means moving to the next line.

A carriage return, \r, means moving the cursor to the beginning of the line.

Ultimately Hello\n\nWorld should result in the following output on the screen:

Hello

     World

Where as Hello\r\rWorld should result in the following output.

It's only when combining the 2 characters \r\n that you have the common understanding of knew line. I.E. Hello\r\nWorld should result in:

Hello
World

And of course \n\r would result in the same visual output as \r\n.

Originally computers took \r and \n quite literally. However these days the support for carriage return is sparse. Usually on every system you can get away with using \n on its own. It never depends on the OS, but it does depend on what you're viewing the output in.

Still I'd always advise using \r\n wherever you can!

Also you can add <br> instead of \n.

And then you can add text to TexView:

articleTextView.setText(Html.fromHtml(textForTextView));

First of all, don't loop while (!eof()), it will not work as you expect it to because the eofbit will not be set until after a failed read due to end of file.

Secondly, the normal input operator >> separates on whitespace and so can be used to read "words":

std::string word;
while (file >> word)
{
    ...
}

If you want to find the last populated cell in a particular column, the best method is:

Range("A" & Rows.Count).End(xlUp).Row

This code uses the very last cell in the entire column (65536 for Excel 2003, 1048576 in later versions), and then find the first populated cell above it. This has the ability to ignore "breaks" in your data and find the true last row.

Answer: NO

Here's Why ... I think a key reason for having stored procs in a database is that you're executing SP code in the same process as the SQL engine. This makes sense for database engines designed to work as a network connected service but the imperative for SQLite is much less given that it runs as a DLL in your application process rather than in a separate SQL engine process. So it makes more sense to implement all your business logic including what would have been SP code in the host language.

You can however extend SQLite with your own user defined functions in the host language (PHP, Python, Perl, C#, Javascript, Ruby etc). You can then use these custom functions as part of any SQLite select/update/insert/delete. I've done this in C# using DevArt's SQLite to implement password hashing.

That's what echo does:

echo "Some text here." > myfile.txt

Just one line and you are done (make sure mysql command is available as global or just go to mysql installation folder and enter into bin folder)

mysql -u database_user_name -p -D database_name < complete_file_path_with_file_name_and_extension 

Here

• u stands for User
• p stands for Password
• D stands for Database

---DON'T FORGET TO ADD < SIGN AFTER DATABASE NAME---

Complete file path with name and extension can be like

c:\folder_name\"folder name"\sql_file.sql

---IF YOUR FOLDER AND FILE NAME CONTAINS SPACE THAN BIND THEM USING DOUBLE QUOTE---

Tip and Note: You can write your password after -p but this is not recommended because it will show to others who are watching your screen at that time, if you don't write there it will ask you when you will execute command by pressing enter.

Git is just trying to guess for you what you are trying to do. It is making every attempt to preserve unbroken history. Of course, it is not perfect. So git mv allows you to be explicit with your intention and to avoid some errors.

Consider this example. Starting with an empty repo,

git init
echo "First" >a
echo "Second" >b
git add *
git commit -m "initial commit"
mv a c
mv b a
git status

Result:

# On branch master
# Changes not staged for commit:
#   (use "git add/rm <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#   modified:   a
#   deleted:    b
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#   c
no changes added to commit (use "git add" and/or "git commit -a")

Autodetection failed :( Or did it?

$ git add *
$ git commit -m "change"
$ git log c

    initial commit

Now try instead (remember to delete the .git folder when experimenting):

git init
echo "First" >a
echo "Second" >b
git add *
git commit -m "initial commit"
git mv a c
git status

So far so good:

# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   renamed:    a -> c


git mv b a
git status

Now, nobody is perfect:

# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   modified:   a
#   deleted:    b
#   new file:   c
#

Really? But of course...

git add *
git commit -m "change"
git log c
git log --follow c

...and the result is the same as above: only --follow shows the full history.

Now, be careful with renaming, as either option can still produce weird effects. Example:

git init
echo "First" >a
git add a
git commit -m "initial a"
echo "Second" >b
git add b
git commit -m "initial b"

git mv a c
git commit -m "first move"
git mv b a
git commit -m "second move"

git log --follow a

git mv a c
git mv b a

    initial a

Ups... Now the history is going back to initial a instead of initial b, which is wrong. So when we did two moves at a time, Git became confused and did not track the changes properly. By the way, in my experiments the same happened when I deleted/created files instead of using git mv. Proceed with care; you've been warned...

CSS3 allows this sort of thing and it looks like this:

body {
    background-image: url(images/bgtop.png), url(images/bg.png);
    background-repeat: repeat-x, repeat;
}

The current versions of all the major browsers now support it, however if you need to support IE8 or below, then the best way you can work around it is to have extra divs:

<body>
    <div id="bgTopDiv">
        content here
    </div>
</body>

body{
    background-image: url(images/bg.png);
}
#bgTopDiv{
    background-image: url(images/bgTop.png);
    background-repeat: repeat-x;
}

Take a look at this similar question. Tool to discover same class..

I think the most relevant obstacle is if you have a custom classloader ( loading from a db or ldap )

Strictly,

other = s if s is not None else "default value"

Otherwise, s = False will become "default value", which may not be what was intended.

If you want to make this shorter, try:

def notNone(s,d):
    if s is None:
        return d
    else:
        return s

other = notNone(s, "default value")

If you look into CREATE PROCEDURE Syntax for latest MySQL version you'll see that procedure parameter can only contain IN/OUT/INOUT specifier, parameter name and type.

So, default values are still unavailable in latest MySQL version.

I just had the same issue and this helped me:

html {
    height: auto;
    min-height: 100%;
    background-size:cover;
}

In CSS2.1, an element can only have at most one of any kind of pseudo-element at any time. (This means an element can have both a :before and an :after pseudo-element — it just cannot have more than one of each kind.)

As a result, when you have multiple :before rules matching the same element, they will all cascade and apply to a single :before pseudo-element, as with a normal element. In your example, the end result looks like this:

.circle.now:before {
    content: "Now";
    font-size: 19px;
    color: black;
}

As you can see, only the content declaration that has highest precedence (as mentioned, the one that comes last) will take effect — the rest of the declarations are discarded, as is the case with any other CSS property.

This behavior is described in the Selectors section of CSS2.1:

Pseudo-elements behave just like real elements in CSS with the exceptions described below and elsewhere.

This implies that selectors with pseudo-elements work just like selectors for normal elements. It also means the cascade should work the same way. Strangely, CSS2.1 appears to be the only reference; neither css3-selectors nor css3-cascade mention this at all, and it remains to be seen whether it will be clarified in a future specification.

If an element can match more than one selector with the same pseudo-element, and you want all of them to apply somehow, you will need to create additional CSS rules with combined selectors so that you can specify exactly what the browser should do in those cases. I can't provide a complete example including the content property here, since it's not clear for instance whether the symbol or the text should come first. But the selector you need for this combined rule is either .circle.now:before or .now.circle:before — whichever selector you choose is personal preference as both selectors are equivalent, it's only the value of the content property that you will need to define yourself.

If you still need a concrete example, see my answer to this similar question.

The legacy css3-content specification contains a section on inserting multiple ::before and ::after pseudo-elements using a notation that's compatible with the CSS2.1 cascade, but note that that particular document is obsolete — it hasn't been updated since 2003, and no one has implemented that feature in the past decade. The good news is that the abandoned document is actively undergoing a rewrite in the guise of css-content-3 and css-pseudo-4. The bad news is that the multiple pseudo-elements feature is nowhere to be found in either specification, presumably owing, again, to lack of implementer interest.

Since there are no events available to signal when the socket is disconnected, you will have to poll it at a frequency that is acceptable to you.

Using this extension method, you can have a reliable method to detect if a socket is disconnected.

static class SocketExtensions
{
  public static bool IsConnected(this Socket socket)
  {
    try
    {
      return !(socket.Poll(1, SelectMode.SelectRead) && socket.Available == 0);
    }
    catch (SocketException) { return false; }
  }
}

This stored procedure inserts a rand number into a table. Look out, it inserts an endless numbers. Stop executing it when u get enough numbers.

create a table for the cursor:

CREATE TABLE [dbo].[SearchIndex](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Cursor] [nvarchar](255) NULL) 

GO

Create a table to contain your numbers:

CREATE TABLE [dbo].[ID](
[IDN] [int] IDENTITY(1,1) NOT NULL,
[ID] [int] NULL)

INSERTING THE SCRIPT :

INSERT INTO [SearchIndex]([Cursor])  SELECT N'INSERT INTO ID  SELECT   FLOOR(rand() * 9 + 1)  SELECT COUNT (ID) FROM ID

CREATING AND EXECUTING THE PROCEDURE:

CREATE PROCEDURE [dbo].[RandNumbers] AS
BEGIN
Declare  CURSE  CURSOR  FOR (SELECT  [Cursor] FROM [dbo].[SearchIndex]  WHERE [Cursor] IS NOT NULL)
DECLARE @RandNoSscript NVARCHAR (250)
OPEN CURSE
FETCH NEXT FROM CURSE
INTO @RandNoSscript 
WHILE @@FETCH_STATUS IS NOT NULL 
BEGIN
Print @RandNoSscript
EXEC SP_EXECUTESQL @RandNoSscript;  
 END
 END
GO

Fill your table:

EXEC RandNumbers

If you want to consider null values equality too, try the following

select column1, column2, 
   case
      when column1 is NULL and column2 is NULL then 'true'  
      when column1=column2 then 'true' 
      else 'false' 
   end 
from table;

If you're more comfortable PCRE regex syntax, which

1. supports the non-greedy operator ?, as you asked in OP; and
2. doesn't require backwhacking grouping and cardinality operators (an utterly counterintuitive vim syntax requirement since you're not matching literal characters but specifying operators); and

3. you have [g]vim compiled with perl feature, test using

   :ver and inspect features; if +perl is there you're good to go)

try search/replace using

:perldo s///

Example. Swap src and alt attributes in img tag:

:perldo s/(src=".*?")\s+(alt=".*?")/$2 $1/

<p class="logo"><a href="/"><img alt="" src="/caminoglobal_en/includes/themes/camino/images/header_logo.png"></a></p>

Use os.path.getsize(path) which will

Return the size, in bytes, of path. Raise OSError if the file does not exist or is inaccessible.

Uint8Array create a array filled with a number up to 3 digits which would be a maximum of 999. This code is very short.

This is just off the top of my head, but you could do an onClick event for each radio button, give them all different IDs, and then make a for loop in the event to go through each radio button in the group and find which is was checked by looking at the 'checked' attribute. The id of the checked one would be stored as a variable, but you might want to use a temp variable first to make sure that the value of that variable changed, since the click event would fire whether or not a new radio button was checked.

This works from command line :

$ export LANG=en_US.UTF-8

None of the other answers above worked for me

Guess I'm a bit late to the party, and although I agree that creating a seperate key for development (localhost) and product it is possible to do both in only 1 key.

When you use Application restrictions -> http referers -> Website restricitions you can enter wildcard urls.

However using a wildcard like .localhost/ or .localhost:{port}. (when already having .yourwebsite.com/* ) don't seem to work.

Just putting a single * does work but this basicly gives you an unlimited key which is not what you want either.

When you include the full path withhout using the wildcard * it also works, so in my case putting:

http://localhost{port}/
http://localhost:{port}/something-else/here

Makes the Google maps work both local as on www.yourwebsite.com using the same API key.

Anyway when having 2 seperate keys is also an option I would advise to do that.

Okay, of course the question has been answered, but no-one seems to notice the third line of your code. It continuosly bugged me.

    <?php
    mysqli_connect("localhost","root","","web_table");
    mysql_select_db("web_table") or die(mysql_error());

for some reason, you made a mysqli connection to server, but you are trying to make a mysql connection to database.To get going, rather use

       $link = mysqli_connect("localhost","root","","web_table");
       mysqli_select_db ($link , "web_table" ) or die.....

or for where i began

     <?php $connection = mysqli_connect("localhost","root","","web_table");       
      global $connection; // global connection to databases - kill it once you're done

or just query with a $connection parameter as the other argument like above. Get rid of that third line.

I found this worked best for me.

In AndroidManifest.xml <activity> element add android:windowSoftInputMode="stateHidden"

This always hides the keyboard when entering the activity.

If on OSX or *NIX use

Get all actual lines of java code from *.java files

find . -name "*.java" -exec grep "[a-zA-Z0-9{}]" {} \; | wc -l

Get all lines from the *.java files, which includes empty lines and comments

find . -name "*.java" -exec cat | wc -l

Get information per File, this will give you [ path to file + "," + number of lines ]

find . -name "*.java" -exec wc -l {} \;

Update: Since Python 3.5 you can use type hints which is a compact, machine-readable syntax:

from typing import Dict, Union

def foo(i: int, d: Dict[str, Union[str, int]]) -> int:
    """
    Explanation: this function takes two arguments: `i` and `d`.
    `i` is annotated simply as `int`. `d` is a dictionary with `str` keys
    and values that can be either `str` or `int`.

    The return type is `int`.

    """

The main advantage of this syntax is that it is defined by the language and that it's unambiguous, so tools like PyCharm can easily take advantage from it.

I'm using the following code in xml

android:adjustViewBounds="true"
android:scaleType="centerInside"

I know it's a relative old post but, I would like to share what worked for me: I've simply input "http://" before "localhost" in the url. Hope it helps somebody.

you can use:

$window.open(url, windowName, attributes);

I once had to use CDATA when my xml element needed to store HTML code. Something like

<codearea>
  <![CDATA[ 
  <div> <p> my para </p> </div> 
  ]]>
</codearea>

So CDATA means it will ignore any character which could otherwise be interpreted as XML tag like < and > etc.

For posterity....I figured out how to get what I needed. Here it is in case it might be useful to somebody else.

The + (String Concatenation) does not work on SQL Server for the image, ntext, or text data types.

In fact, image, ntext, and text are all deprecated.

ntext, text, and image data types will be removed in a future version of MicrosoftSQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

That said if you are using an older version of SQL Server than you want to use UPDATETEXT to perform your concatenation. Which Colin Stasiuk gives a good example of in his blog post String Concatenation on a text column (SQL 2000 vs SQL 2005+).

I am getting this issue when using owl carousal and scrolling the images.

So get solved just adding below CSS in your page.

or

.owl-carousel {

touch-action: none;

CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
WHERE dest.dbid = DB_ID('msdb')
ORDER BY deqs.last_execution_time DESC

This is the same answer that Aaron Bertrand provided but it wasn't placed in an answer.

How about something like

package main

import (
    "fmt"
    "time"
)

func schedule(what func(), delay time.Duration) chan bool {
    stop := make(chan bool)

    go func() {
        for {
            what()
            select {
            case <-time.After(delay):
            case <-stop:
                return
            }
        }
    }()

    return stop
}

func main() {
    ping := func() { fmt.Println("#") }

    stop := schedule(ping, 5*time.Millisecond)
    time.Sleep(25 * time.Millisecond)
    stop <- true
    time.Sleep(25 * time.Millisecond)

    fmt.Println("Done")
}

If you're on java 6 can use NetworkInterface to check for available network interfaces. I.e. something like this:

Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();
while (interfaces.hasMoreElements()) {
  NetworkInterface interf = interfaces.nextElement();
  if (interf.isUp() && !interf.isLoopback())
    return true;
}

Haven't tried it myself, yet.

I liked the answer from kays1 but I couldn't implement it. So I built my own version using his concept.

public class JsonListHelper{
    public static final <T> List<T> getList(String json) throws Exception {
        Gson gson = new GsonBuilder().setDateFormat("yyyy-MM-dd HH:mm:ss").create();
        Type typeOfList = new TypeToken<List<T>>(){}.getType();
        return gson.fromJson(json, typeOfList);
    }
}

Usage:

List<MyClass> MyList= JsonListHelper.getList(jsonArrayString);

if object_id ('tempdb..#tempreport') is not null
begin  
drop table #tempreport
end 
create table #tempreport (
Category  nvarchar(510),
CreationDate smallint )
insert into #tempreport 
select distinct Category from MonitoringJob (nolock) 
select * from #tempreport  ORDER BY CreationDate DESC

@Maxx has an excellent answer, use the unittest tools provided by Python:

import unittest


class Test(unittest.TestCase):
    def runTest(self):
        pass

    def testDict(self, d1, d2, maxDiff=None):
        self.maxDiff = maxDiff
        self.assertDictEqual(d1, d2)

Then, anywhere in your code you can call:

try:
    Test().testDict(dict1, dict2)
except Exception, e:
    print e

The resulting output looks like the output from diff, pretty-printing the dictionaries with + or - prepending each line that is different.

This is due to Morphia jar not being part of your output war/jar. Eclipse or local build includes them as part of classpath, but remote builds or auto/scheduled build don't consider them part of classpath.

Adding to above answer if we want to format Double multiple times, we can use protocol extension of Double like below:

extension Double {
    var dollarString:String {
        return String(format: "$%.2f", self)

}

let a = 45.666

print(a.dollarString) //will print "$45.67"

It works with any type without an issue. If the result is DBNull, it returns null as the conversion fails.

When you're doing this

var model = @Html.Raw(Json.Encode(Model));

You're probably getting a JSON string, and not a JavaScript object.

You need to parse it in to an object:

var model = JSON.parse(model); //or $.parseJSON() since if jQuery is included
console.log(model.Sections);

$array[9] = 'Apple';
$array[12] = 'Orange';
$array[5] = 'Peach';

$array = array_values($array);

through this function you can reset your array

$array[0] = 'Apple';
$array[1] = 'Orange';
$array[2] = 'Peach';

According to the official documentation on sitemaps.org it needs to be a full URL:

You can specify the location of the Sitemap using a robots.txt file. To do this, simply add the following line including the full URL to the sitemap:

Sitemap: http://www.example.com/sitemap.xml

You can try this one

img{
    max-height:500px;
    max-width:500px;
    height:auto;
    width:auto;
}

This keeps the aspect ratio of the image and prevents either the two dimensions exceed 500px

Just small addition to explanation

This structure (function() {})(); is called IIFE (Immediately Invoked Function Expression), it will be executed immediately, when the interpreter will reach this line. So when you're writing these rows:

(function($) {
  // do something
})(jQuery);

this means, that the interpreter will invoke the function immediately, and will pass jQuery as a parameter, which will be used inside the function as $.

' is not part of the HTML 4 standard.

" is, though, so is fine to use.

For security reasons, it is not possible to get the real, full path of a file, referred through an <input type="file" /> element.

This question already mentions, and links to other Stack Overflow questions regarding this topic.

string = string.split("\\");

In JavaScript, the backslash is used to escape special characters, such as newlines (\n). If you want to use a literal backslash, a double backslash has to be used.

So, if you want to match two backslashes, four backslashes has to be used. For example,alert("\\\\") will show a dialog containing two backslashes.

Instead of using ->bindParam() you can pass the data only at the time of ->execute():

$data = [   ':item_name' => $_POST['item_name'],   ':item_type' => $_POST['item_type'],   ':item_price' => $_POST['item_price'],   ':item_description' => $_POST['item_description'],   ':image_location' => 'images/'.$_FILES['file']['name'],   ':status' => 0,   ':id' => 0, ];  $stmt->execute($data); 

In this way you would know exactly what values are going to be sent.

bit late but nevermind easy one is

import autopy
import time
time.sleep(2)
b = autopy.bitmap.capture_screen()
b.save("C:/Users/mak/Desktop/m.png")

EDIT: I've added one more option for bootstrap sidebars.

There are actually three manners in which you can make a bootstrap 3 sidebar. I tried to keep the code as simple as possible.

Fixed sidebar

Here you can see a demo of a simple fixed sidebar I've developed with the same height as the page

Sidebar in a column

I've also developed a rather simple column sidebar that works in a two or three column page inside a container. It takes the length of the longest column. Here you can see a demo

Dashboard

If you google bootstrap dashboard, you can find multiple suitable dashboard, such as this one. However, most of them require a lot of coding. I've developed a dashboard that works without additional javascript (next to the bootstrap javascript). Here is a demo

For all three examples you off course have to include the jquery, bootstrap css, js and theme.css files.

Slidebar

If you want the sidebar to hide on pressing a button this is also possible with only a little javascript.Here is a demo

I don't agree with the statement about [...] HTTP referrer leakage (an external image in the target page might leak the password) in Slough's response.

The HTTP 1.1 RFC explicitly states:

Clients SHOULD NOT include a Referer header field in a (non-secure) HTTP request if the referring page was transferred with a secure protocol.

Anyway, server logs and browser history are more than sufficient reasons not to put sensitive data in the query string.

This helped me:

<p>Date/Time: <span id="datetime"></span></p><script>var dt = new Date();
document.getElementById("datetime").innerHTML=dt.toLocaleString();</script>    

Right click on the page and choose 'inspect element'. In the screen that opens now (the developer tools), clicking the second icon from the left @ the bottom of it opens a console, where you can type javascript. The console is linked to the current page.

You can find a nice list of corresponding URL encoded characters on W3Schools.

• + becomes %2B
• space becomes %20

Imagine the include as what it is: A copy & paste of the contents of the included PHP file which will then be interpreted. There is no scope change at all, so you can still access $someVar in the included file directly (even though you might consider a class based structure where you pass $someVar as a parameter or refer to a few global variables).

Now the answer for your question is yes, it will just work by copying the standard snippet. According to documentation, now the standard snippet has automatic cookie domain configuration: ga('create', 'UA-XXXXX-Y', 'auto'); where cookie domain is automatically determined.

In addition, if analytics.js detects that you're running a server locally (e.g. localhost) it automatically sets the cookieDomain to 'none'.

First off target refers to the BlockID found in either HTML code or chromes developer tools that you are trying to link to. Each code is different and you will need to do some digging to find the ID you are trying to reference. It should look something like div class="page-container drawer-page-content" id"PageContainer"Note that this is the format for the whole referenced section, not an individual text or image. To do that you would need to find the same piece of code but relating to your target block. For example dv id="your-block-id" Anyways I was just reading over this thread and an idea came to my mind, if you are a Shopify user and want to do this it is pretty much the same thing as stated. But instead of

> http://url.to.site/index.html#target

You would put

> http://storedomain.com/target

For example, I am setting up a disclaimer page with links leading to a newsletter signup and shopping blocks on my home page so I insert https://mystore-classifier.com/#shopify-section-1528945200235 for my hyperlink. Please note that the -classifier is for my internal use and doesn't apply to you. This is just so I can keep track of my stores. If you want to link to something other than your homepage you would put

> http://mystore-classifier.com/pagename/#BlockID

I hope someone found this useful, if there is something wrong with my explanation please let me know as I am not an HTML programmer my language is C#!

It might be cleaner if you have a function, say called vprint, that checks the verbose flag for you. Then you just call your own vprint function any place you want optional verbosity.

^{The original query used user variables and ORDER BY on derived tables; the behavior of both quirks is not guaranteed. Revised answer as follows.}

In MySQL 5.x you can use poor man's rank over partition to achieve desired result. Just outer join the table with itself and for each row, count the number of rows lesser than it. In the above case, lesser row is the one with higher rate:

SELECT t.id, t.rate, t.year, COUNT(l.rate) AS rank
FROM t
LEFT JOIN t AS l ON t.id = l.id AND t.rate < l.rate
GROUP BY t.id, t.rate, t.year
HAVING COUNT(l.rate) < 5
ORDER BY t.id, t.rate DESC, t.year

Demo and Result:

| id  | rate | year | rank |
|-----|------|------|------|
| p01 |  8.0 | 2006 | 0    |
| p01 |  7.4 | 2003 | 1    |
| p01 |  6.8 | 2008 | 2    |
| p01 |  5.9 | 2001 | 3    |
| p01 |  5.3 | 2007 | 4    |
| p02 | 12.5 | 2001 | 0    |
| p02 | 12.4 | 2004 | 1    |
| p02 | 12.2 | 2002 | 2    |
| p02 | 10.3 | 2003 | 3    |
| p02 |  8.7 | 2000 | 4    |

Note that if the rates had ties, for example:

100, 90, 90, 80, 80, 80, 70, 60, 50, 40, ...

The above query will return 6 rows:

100, 90, 90, 80, 80, 80

Change to HAVING COUNT(DISTINCT l.rate) < 5 to get 8 rows:

100, 90, 90, 80, 80, 80, 70, 60

Or change to ON t.id = l.id AND (t.rate < l.rate OR (t.rate = l.rate AND t.pri_key > l.pri_key)) to get 5 rows:

 100, 90, 90, 80, 80

In MySQL 8 or later just use the RANK, DENSE_RANK or ROW_NUMBER functions:

SELECT *
FROM (
    SELECT *, RANK() OVER (PARTITION BY id ORDER BY rate DESC) AS rnk
    FROM t
) AS x
WHERE rnk <= 5

Have a look at Access Modifiers (C# Programming Guide)

Class and Struct Accessibility

Classes and structs that are declared directly within a namespace (in other words, that are not nested within other classes or structs) can be either public or internal. Internal is the default if no access modifier is specified.

Struct members, including nested classes and structs, can be declared as public, internal, or private. Class members, including nested classes and structs, can be public, protected internal, protected, internal, private protected or private. The access level for class members and struct members, including nested classes and structs, is private by default. Private nested types are not accessible from outside the containing type.

Derived classes cannot have greater accessibility than their base types. In other words, you cannot have a public class B that derives from an internal class A. If this were allowed, it would have the effect of making A public, because all protected or internal members of A are accessible from the derived class.

You can enable specific other assemblies to access your internal types by using the InternalsVisibleToAttribute. For more information, see Friend Assemblies.

Class and Struct Member Accessibility

Class members (including nested classes and structs) can be declared with any of the six types of access. Struct members cannot be declared as protected because structs do not support inheritance.

Normally, the accessibility of a member is not greater than the accessibility of the type that contains it. However, a public member of an internal class might be accessible from outside the assembly if the member implements interface methods or overrides virtual methods that are defined in a public base class.

The type of any member that is a field, property, or event must be at least as accessible as the member itself. Similarly, the return type and the parameter types of any member that is a method, indexer, or delegate must be at least as accessible as the member itself. For example, you cannot have a public method M that returns a class C unless C is also public. Likewise, you cannot have a protected property of type A if A is declared as private.

User-defined operators must always be declared as public and static. For more information, see Operator overloading.

Finalizers cannot have accessibility modifiers.

Other Types

Interfaces declared directly within a namespace can be declared as public or internal and, just like classes and structs, interfaces default to internal access. Interface members are always public because the purpose of an interface is to enable other types to access a class or struct. No access modifiers can be applied to interface members.

Enumeration members are always public, and no access modifiers can be applied.

Delegates behave like classes and structs. By default, they have internal access when declared directly within a namespace, and private access when nested.

I have stumbled upon this problem for one hour. After an hour, I tried debugging and this helped:

$('.list').on('click', 'span', (e) => {
  $(e.target).parent().remove();
});

HTML:

<ul class="list">
  <li class="task">some text<span>X</span></li>
  <li class="task">some text<span>X</span></li>
  <li class="task">some text<span>X</span></li>
  <li class="task">some text<span>X</span></li>
  <li class="task">some text<span>X</span></li>
</ul>

Yes, == is bad for comparing Strings (any objects really, unless you know they're canonical). == just compares object references. .equals() tests for equality. For Strings, often they'll be the same but as you've discovered, that's not guaranteed always.

For linux users, you should know the following:

1. $CLASSPATH is specifically what Java uses to look through multiple directories to find all the different classes it needs for your script (unless you explicitly tell it otherwise with the -cp override). Using -cp (--classpath) requires that you keep track of all the directories manually and copy-paste that line every time you run the program (not preferable IMO).

2. The colon (":") character separates the different directories. There is only one $CLASSPATH and it has all the directories in it. So, when you run "export CLASSPATH=...." you want to include the current value "$CLASSPATH" in order to append to it. For example:

   export CLASSPATH=.
   export CLASSPATH=$CLASSPATH:/usr/share/java/mysql-connector-java-5.1.12.jar
   

   In the first line above, you start CLASSPATH out with just a simple 'dot' which is the path to your current working directory. With that, whenever you run java it will look in the current working directory (the one you're in) for classes. In the second line above, $CLASSPATH grabs the value that you previously entered (.) and appends the path to a mysql dirver. Now, java will look for the driver AND for your classes.

3. echo $CLASSPATH
   

   is super handy, and what it returns should read like a colon-separated list of all the directories you want java looking in for what it needs to run your script.

4. Tomcat does not use CLASSPATH. Read what to do about that here: https://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html

If you want a specific order, then you must use an array, not an object. Objects do not have a defined order.

For example, using an array, you could do this:

var myobj = [{"A":["B"]}, {"B": ["C"]}];
var firstItem = myobj[0];

Then, you can use myobj[0] to get the first object in the array.

Or, depending upon what you're trying to do:

var myobj = [{key: "A", val:["B"]}, {key: "B",  val:["C"]}];
var firstKey = myobj[0].key;   // "A"
var firstValue = myobj[0].val; // "["B"]

I like this, so that you can add whatever fields you want and print it that way.

function printPage() {
    var w = window.open();

    var headers =  $("#headers").html();
    var field= $("#field1").html();
    var field2= $("#field2").html();

    var html = "<!DOCTYPE HTML>";
    html += '<html lang="en-us">';
    html += '<head><style></style></head>';
    html += "<body>";

    //check to see if they are null so "undefined" doesnt print on the page. <br>s optional, just to give space
    if(headers != null) html += headers + "<br/><br/>";
    if(field != null) html += field + "<br/><br/>";
    if(field2 != null) html += field2 + "<br/><br/>";

    html += "</body>";
    w.document.write(html);
    w.window.print();
    w.document.close();
};

not elegant but does the job (removes trailing zeros)

var num = 0.1*0.2;
alert(parseFloat(num.toFixed(10))); // shows 0.02

There are a lot of correct/same answers, but for future references:

Same stands for Tomcat 7. Be aware that updating only your used frameworks' versions (as proposed in other similar questions) isn't enough.

You also have to update Tomcat plugin's version. What worked for me, using Java 7, was upgrading to version 2.2 of tomcat7-maven-plugin (= Tomcat 7.0.47).

LIBS  = -lkernel32 -luser32 -lgdi32 -lopengl32
CFLAGS = -Wall

# Should be equivalent to your list of C files, if you don't build selectively
SRC=$(wildcard *.c)

test: $(SRC)
    gcc -o $@ $^ $(CFLAGS) $(LIBS)

Check the server configuration and folders' routes:

1. Open servers view (Window -> Open view... -> Others... -> Search for 'servers'.

2. Right click on server (mine is Tomcat v6.0) -> properties -> Click on 'Swicth Location' (check that location's like /servers...

3. Double click on the server. This will open a new servers page. In the 'Servers Locations' area, check the 'Use Tomcat Installation (takes control of Tomcat Installation)' option.

4. Restart your server.

5. Enjoy!

If your example represents your real code, the problem is not in the push, it's that your constructor doesn't do anything.

You need to declare and initialize the x and y members.

Explicitly:

export class Pixel {
    public x: number;
    public y: number;   
    constructor(x: number, y: number) {
        this.x = x;
        this.y = y;
    }
}

Or implicitly:

export class Pixel {
    constructor(public x: number, public y: number) {}
}

If you want to delete items after some time, e.g. after a month, just use Time To Live option. It will not count write units.

In your case, I would add ttl when logs expire and leave those after a user is deleted. TTL would make sure logs are removed eventually.

When Time To Live is enabled on a table, a background job checks the TTL attribute of items to see if they are expired.

DynamoDB typically deletes expired items within 48 hours of expiration. The exact duration within which an item truly gets deleted after expiration is specific to the nature of the workload and the size of the table. Items that have expired and not been deleted will still show up in reads, queries, and scans. These items can still be updated and successful updates to change or remove the expiration attribute will be honored.

Use regex pattern ^(?=.{8})(?=.*[^a-zA-Z])

Explanation:

^(?=.{8})(?=.*[^a-zA-Z])
¦+------++-------------+
¦   ¦           ¦
¦   ¦           + string contains some non-letter character
¦   ¦
¦   + string contains at least 8 characters
¦
+ begining of line/string

If you want to limit also maximum length (let's say 16), then use regex pattern:

^(?=.{8,16}$)(?=.*[^a-zA-Z])

Another method utilizing the dplyr package:

library(dplyr)
df <- mtcars %>%
        filter(mpg > 25)

Without the chain (%>%) operator:

library(dplyr)
df <- filter(mtcars, mpg > 25)

It did not worked for me until i created:

#created cc string
cc = ""[email protected];
#added cc to header
msg['Cc'] = cc

and than added cc in recipient [list] like:

s.sendmail(me, [you,cc], msg.as_string())

Take a look at TOMEE

It has all the features that you need to build a complete Java EE app.

If you use the NetBeans IDE (latest version at this time is 6.5.1), you can use it to create a basic GUI java application using File->New Project and choose the Java category then Java Desktop Application.

Once created, you will have a simple bare bones GUI app which contains an about box that can be opened using a menu selection. You should be able to adapt this to your needs and learn how to open a dialog from a button click.

You will be able to edit the dialog visually. Delete the items that are there and add some text areas. Play around with it and come back with more questions if you get stuck :)

From this link http://www.svennerberg.com/2009/09/google-maps-api-3-infowindows/:

Teo: The easiest way to do this is to just have one instance of the InfoWindow object that you reuse over and over again. That way when you click a new marker the infoWindow is “moved” from where it’s currently at, to point at the new marker.

Use its setContent method to load it with the correct content.

My usual methodology for choosing is something like:

• GET for items that will be retrieved later by URL
  • E.g. Search should be GET so you can do search.php?s=XXX later on
• POST for items that will be sent
  • This is relatively invisible comapred to GET and harder to send, but data can still be sent via cURL.

This might be a little late. But here is one of the usage. This to get the count of the number of files.

Create a pointer to memory (a new obj in this case) and have the property of the object modified. Java 8 stream doesn't allow to modify the pointer itself and hence if you declare just count as a variable and try to increment within the stream it will never work and throw a compiler exception in the first place

Path path = Paths.get("/Users/XXXX/static/test.txt");



Count c = new Count();
            c.setCount(0);
            Files.lines(path).forEach(item -> {
                c.setCount(c.getCount()+1);
                System.out.println(item);});
            System.out.println("line count,"+c);

public static class Count{
        private int count;

        public int getCount() {
            return count;
        }

        public void setCount(int count) {
            this.count = count;
        }

        @Override
        public String toString() {
            return "Count [count=" + count + "]";
        }



    }

This should return the directory name followed by the number of files in the directory.

findfiles() {
    echo "$1" $(find "$1" -maxdepth 1 -type f | wc -l)
}

export -f findfiles

find ./ -type d -exec bash -c 'findfiles "$0"' {} \;

Example output:

./ 6
./foo 1
./foo/bar 2
./foo/bar/bazzz 0
./foo/bar/baz 4
./src 4

The export -f is required because the -exec argument of find does not allow executing a bash function unless you invoke bash explicitly, and you need to export the function defined in the current scope to the new shell explicitly.

You simply need to enable it in the config.php and you can use $this->input->get('param_name'); to get parameters.

Do you mean this?

var listOfList = new List<List<int>>() {
    new List<int>() { 1, 2 },
    new List<int>() { 3, 4 },
    new List<int>() { 5, 6 }
};
var list = new List<int> { 9, 9, 9 };
var result = list.Concat(listOfList.SelectMany(x => x));

foreach (var x in result) Console.WriteLine(x);

Results in: 9 9 9 1 2 3 4 5 6

@mshobnr / @olegkhuss solution made into a simple macro:

{% macro trunc(txt, len) -%}
    {{ txt|length > len ? txt|slice(0, len) ~ '…' : txt }}
{%- endmacro %}

Usage example:

{{ tools.trunc('This is the text to truncate. ', 50) }}

N.b. I import a Twig template containing macros and import it as 'tools' like this (Symfony):

{% import "@AppBundle/tools.html.twig" as tools -%}

Also, I replaced the html character code with the actual character, this should be no problem when using UTF-8 as the file encoding. This way you don't have to use |raw (as it could cause a security issue).

Depending on whether or not you want to include binary files, there are two solutions.

1. git grep --cached -al '' | xargs -P 4 cat | wc -l

2. git grep --cached -Il '' | xargs -P 4 cat | wc -l
   

   "xargs -P 4" means it can read the files using four parallel processes. This can be really helpful if you are scanning very large repositories. Depending on capacity of the machine you may increase number of processes.

   -a, process binary files as text (Include Binary)
   -l '', show only filenames instead of matching lines (Scan only non empty files)
   -I, don't match patterns in binary files (Exclude Binary)
   --cached, search in index instead of in the work tree (Include uncommitted files)

We here use simply linear search. At first initialize the index equal to -1 . Then search the array , if found the assign the index value in index variable and break. Otherwise, index = -1.

   int find(int arr[], int n, int key)
   {
     int index = -1;

       for(int i=0; i<n; i++)
       {
          if(arr[i]==key)
          {
            index=i;
            break;
          }
       }
      return index;
    }


 int main()
 {
    int arr[ 5 ] = { 4, 1, 3, 2, 6 };
    int n =  sizeof(arr)/sizeof(arr[0]);
    int x = find(arr ,n, 3);
    cout<<x<<endl;
    return 0;
 }

Use the PHP function

void set_time_limit ( int $seconds )

The maximum execution time, in seconds. If set to zero, no time limit is imposed.

This function has no effect when PHP is running in safe mode. There is no workaround other than turning off safe mode or changing the time limit in the php.ini.

I'd recommend application/octet-stream as RFC2046 says "The "octet-stream" subtype is used to indicate that a body contains arbitrary binary data" and "The recommended action for an implementation that receives an "application/octet-stream" entity is to simply offer to put the data in a file[...]".

I think that way you will get better handling from arbitrary programs, that might barf when encountering your unknown mime type.

If you have sed:

sed -e '/REFERENCE/d' -e '/ERROR/d' [FILENAME]

Where FILENAME is the name of the text file with the good & bad lines

It seems project has been using cocoapods. and that files are missing from your project.

You cant just download it from git. You need to install it from cocoapods.

for more help, you may follow Introduction to CocoaPods Tutorial

If the project uses CocoaPods be aware to always open the .xcworkspace file instead of the .xcodeproj file

As of Python 3.4, the hashlib module in the standard library contains key derivation functions which are "designed for secure password hashing".

So use one of those, like hashlib.pbkdf2_hmac, with a salt generated using os.urandom:

from typing import Tuple
import os
import hashlib
import hmac

def hash_new_password(password: str) -> Tuple[bytes, bytes]:
    """
    Hash the provided password with a randomly-generated salt and return the
    salt and hash to store in the database.
    """
    salt = os.urandom(16)
    pw_hash = hashlib.pbkdf2_hmac('sha256', password.encode(), salt, 100000)
    return salt, pw_hash

def is_correct_password(salt: bytes, pw_hash: bytes, password: str) -> bool:
    """
    Given a previously-stored salt and hash, and a password provided by a user
    trying to log in, check whether the password is correct.
    """
    return hmac.compare_digest(
        pw_hash,
        hashlib.pbkdf2_hmac('sha256', password.encode(), salt, 100000)
    )

# Example usage:
salt, pw_hash = hash_new_password('correct horse battery staple')
assert is_correct_password(salt, pw_hash, 'correct horse battery staple')
assert not is_correct_password(salt, pw_hash, 'Tr0ub4dor&3')
assert not is_correct_password(salt, pw_hash, 'rosebud')

Note that:

• The use of a 16-byte salt and 100000 iterations of PBKDF2 match the minimum numbers recommended in the Python docs. Further increasing the number of iterations will make your hashes slower to compute, and therefore more secure.
• os.urandom always uses a cryptographically secure source of randomness
• hmac.compare_digest, used in is_correct_password, is basically just the == operator for strings but without the ability to short-circuit, which makes it immune to timing attacks. That probably doesn't really provide any extra security value, but it doesn't hurt, either, so I've gone ahead and used it.

For theory on what makes a good password hash and a list of other functions appropriate for hashing passwords with, see https://security.stackexchange.com/q/211/29805.

Convert your x-axis data from text to datetime.datetime, use datetime.strptime:

>>> from datetime import datetime
>>> datetime.strptime("2012-may-31 19:00", "%Y-%b-%d %H:%M")
 datetime.datetime(2012, 5, 31, 19, 0)

This is an example of how to plot data once you have an array of datetimes:

import matplotlib.pyplot as plt
import datetime
import numpy as np

x = np.array([datetime.datetime(2013, 9, 28, i, 0) for i in range(24)])
y = np.random.randint(100, size=x.shape)

plt.plot(x,y)
plt.show()

For bootstrap 4 if you are using Sass here is the variable to edit

// Grid containers
//
// Define the maximum width of `.container` for different screen sizes.

$container-max-widths: (
  sm: 540px,
  md: 720px,
  lg: 960px,
  xl: 1140px
) !default;

To override this variable I declared $container-max-widths without the !default in my .sass file before importing bootstrap.

Note : I only needed to change the xl value so I didn't care to think about breakpoints.

Every object has to be named inside the parent object:

{ "data": {
    "stuff": {
        "onetype": [
            { "id": 1, "name": "" },
            { "id": 2, "name": "" }
        ],
        "othertype": [
            { "id": 2, "xyz": [-2, 0, 2], "n": "Crab Nebula", "t": 0, "c": 0, "d": 5 }
        ]
    },
    "otherstuff": {
        "thing":
            [[1, 42], [2, 2]]
    }
}
}

So you cant declare an object like this:

var obj = {property1, property2};

It has to be

var obj = {property1: 'value', property2: 'value'};

Try:

alert(arguments.callee.toString());

You can do the following to learn/test the concept:

1. Open new Excel Workbook and in Excel VBA editor right-click on Modules->Insert->Module

2. In newly added Module1 add the declaration; Public Global1 As String

3. in Worksheet VBA Module Sheet1(Sheet1) put the code snippet:

Sub setMe()
      Global1 = "Hello"
End Sub

4. in Worksheet VBA Module Sheet2(Sheet2) put the code snippet:

Sub showMe()
    Debug.Print (Global1)
End Sub

5. Run in sequence Sub setMe() and then Sub showMe() to test the global visibility/accessibility of the var Global1

Hope this will help.

import React, { useState } from 'react';

function App() {
  const [apes , setap] = useState('yo');
  const handleClick = () =>{
    setap(document.getElementById('name').value)

Use string append operator on the serial.read(). It works better than string.concat()

char r;
string mystring = "";

while(serial.available()){
    r = serial.read();
    mystring = mystring + r; 
}

After you are done saving the stream in a string(mystring, in this case), use SubString functions to extract what you are looking for.

This code may help you:

double d = double.Parse(input_value);
string output= d.ToString("F2", CultureInfo.InvariantCulture) + "%";

The DateTime constructor takes a parameter string time. $time can be different things, it has to respect the datetime format.

There are some valid values as examples :

• 'now' (the default value)
• 2017-10-19
• 2017-10-19 11:59:59
• 2017-10-19 +1day

So, in your case you can use the following.

$dt = new \DateTime('now +1 day'); //Tomorrow
$dt = new \DateTime('2016-01-01 +1 day'); //2016-01-02

SP is the stack register a shortcut for typing r13. LR is the link register a shortcut for r14. And PC is the program counter a shortcut for typing r15.

When you perform a call, called a branch link instruction, bl, the return address is placed in r14, the link register. the program counter pc is changed to the address you are branching to.

There are a few stack pointers in the traditional ARM cores (the cortex-m series being an exception) when you hit an interrupt for example you are using a different stack than when running in the foreground, you dont have to change your code just use sp or r13 as normal the hardware has done the switch for you and uses the correct one when it decodes the instructions.

The traditional ARM instruction set (not thumb) gives you the freedom to use the stack in a grows up from lower addresses to higher addresses or grows down from high address to low addresses. the compilers and most folks set the stack pointer high and have it grow down from high addresses to lower addresses. For example maybe you have ram from 0x20000000 to 0x20008000 you set your linker script to build your program to run/use 0x20000000 and set your stack pointer to 0x20008000 in your startup code, at least the system/user stack pointer, you have to divide up the memory for other stacks if you need/use them.

Stack is just memory. Processors normally have special memory read/write instructions that are PC based and some that are stack based. The stack ones at a minimum are usually named push and pop but dont have to be (as with the traditional arm instructions).

If you go to http://github.com/lsasim I created a teaching processor and have an assembly language tutorial. Somewhere in there I go through a discussion about stacks. It is NOT an arm processor but the story is the same it should translate directly to what you are trying to understand on the arm or most other processors.

Say for example you have 20 variables you need in your program but only 16 registers minus at least three of them (sp, lr, pc) that are special purpose. You are going to have to keep some of your variables in ram. Lets say that r5 holds a variable that you use often enough that you dont want to keep it in ram, but there is one section of code where you really need another register to do something and r5 is not being used, you can save r5 on the stack with minimal effort while you reuse r5 for something else, then later, easily, restore it.

Traditional (well not all the way back to the beginning) arm syntax:

...
stmdb r13!,{r5}
...temporarily use r5 for something else...
ldmia r13!,{r5}
...

stm is store multiple you can save more than one register at a time, up to all of them in one instruction.

db means decrement before, this is a downward moving stack from high addresses to lower addresses.

You can use r13 or sp here to indicate the stack pointer. This particular instruction is not limited to stack operations, can be used for other things.

The ! means update the r13 register with the new address after it completes, here again stm can be used for non-stack operations so you might not want to change the base address register, leave the ! off in that case.

Then in the brackets { } list the registers you want to save, comma separated.

ldmia is the reverse, ldm means load multiple. ia means increment after and the rest is the same as stm

So if your stack pointer were at 0x20008000 when you hit the stmdb instruction seeing as there is one 32 bit register in the list it will decrement before it uses it the value in r13 so 0x20007FFC then it writes r5 to 0x20007FFC in memory and saves the value 0x20007FFC in r13. Later, assuming you have no bugs when you get to the ldmia instruction r13 has 0x20007FFC in it there is a single register in the list r5. So it reads memory at 0x20007FFC puts that value in r5, ia means increment after so 0x20007FFC increments one register size to 0x20008000 and the ! means write that number to r13 to complete the instruction.

Why would you use the stack instead of just a fixed memory location? Well the beauty of the above is that r13 can be anywhere it could be 0x20007654 when you run that code or 0x20002000 or whatever and the code still functions, even better if you use that code in a loop or with recursion it works and for each level of recursion you go you save a new copy of r5, you might have 30 saved copies depending on where you are in that loop. and as it unrolls it puts all the copies back as desired. with a single fixed memory location that doesnt work. This translates directly to C code as an example:

void myfun ( void )
{
   int somedata;
}

In a C program like that the variable somedata lives on the stack, if you called myfun recursively you would have multiple copies of the value for somedata depending on how deep in the recursion. Also since that variable is only used within the function and is not needed elsewhere then you perhaps dont want to burn an amount of system memory for that variable for the life of the program you only want those bytes when in that function and free that memory when not in that function. that is what a stack is used for.

A global variable would not be found on the stack.

Going back...

Say you wanted to implement and call that function you would have some code/function you are in when you call the myfun function. The myfun function wants to use r5 and r6 when it is operating on something but it doesnt want to trash whatever someone called it was using r5 and r6 for so for the duration of myfun() you would want to save those registers on the stack. Likewise if you look into the branch link instruction (bl) and the link register lr (r14) there is only one link register, if you call a function from a function you will need to save the link register on each call otherwise you cant return.

...
bl myfun
    <--- the return from my fun returns here
...


myfun:
stmdb sp!,{r5,r6,lr}
sub sp,#4 <--- make room for the somedata variable
...
some code here that uses r5 and r6
bl more_fun <-- this modifies lr, if we didnt save lr we wouldnt be able to return from myfun
   <---- more_fun() returns here
...
add sp,#4 <-- take back the stack memory we allocated for the somedata variable
ldmia sp!,{r5,r6,lr}
mov pc,lr <---- return to whomever called myfun.

So hopefully you can see both the stack usage and link register. Other processors do the same kinds of things in a different way. for example some will put the return value on the stack and when you execute the return function it knows where to return to by pulling a value off of the stack. Compilers C/C++, etc will normally have a "calling convention" or application interface (ABI and EABI are names for the ones ARM has defined). if every function follows the calling convention, puts parameters it is passing to functions being called in the right registers or on the stack per the convention. And each function follows the rules as to what registers it does not have to preserve the contents of and what registers it has to preserve the contents of then you can have functions call functions call functions and do recursion and all kinds of things, so long as the stack does not go so deep that it runs into the memory used for globals and the heap and such, you can call functions and return from them all day long. The above implementation of myfun is very similar to what you would see a compiler produce.

ARM has many cores now and a few instruction sets the cortex-m series works a little differently as far as not having a bunch of modes and different stack pointers. And when executing thumb instructions in thumb mode you use the push and pop instructions which do not give you the freedom to use any register like stm it only uses r13 (sp) and you cannot save all the registers only a specific subset of them. the popular arm assemblers allow you to use

push {r5,r6}
...
pop {r5,r6}

in arm code as well as thumb code. For the arm code it encodes the proper stmdb and ldmia. (in thumb mode you also dont have the choice as to when and where you use db, decrement before, and ia, increment after).

No you absolutly do not have to use the same registers and you dont have to pair up the same number of registers.

push {r5,r6,r7}
...
pop {r2,r3}
...
pop {r1}

assuming there is no other stack pointer modifications in between those instructions if you remember the sp is going to be decremented 12 bytes for the push lets say from 0x1000 to 0x0FF4, r5 will be written to 0xFF4, r6 to 0xFF8 and r7 to 0xFFC the stack pointer will change to 0x0FF4. the first pop will take the value at 0x0FF4 and put that in r2 then the value at 0x0FF8 and put that in r3 the stack pointer gets the value 0x0FFC. later the last pop, the sp is 0x0FFC that is read and the value placed in r1, the stack pointer then gets the value 0x1000, where it started.

The ARM ARM, ARM Architectural Reference Manual (infocenter.arm.com, reference manuals, find the one for ARMv5 and download it, this is the traditional ARM ARM with ARM and thumb instructions) contains pseudo code for the ldm and stm ARM istructions for the complete picture as to how these are used. Likewise well the whole book is about the arm and how to program it. Up front the programmers model chapter walks you through all of the registers in all of the modes, etc.

If you are programming an ARM processor you should start by determining (the chip vendor should tell you, ARM does not make chips it makes cores that chip vendors put in their chips) exactly which core you have. Then go to the arm website and find the ARM ARM for that family and find the TRM (technical reference manual) for the specific core including revision if the vendor has supplied that (r2p0 means revision 2.0 (two point zero, 2p0)), even if there is a newer rev, use the manual that goes with the one the vendor used in their design. Not every core supports every instruction or mode the TRM tells you the modes and instructions supported the ARM ARM throws a blanket over the features for the whole family of processors that that core lives in. Note that the ARM7TDMI is an ARMv4 NOT an ARMv7 likewise the ARM9 is not an ARMv9. ARMvNUMBER is the family name ARM7, ARM11 without a v is the core name. The newer cores have names like Cortex and mpcore instead of the ARMNUMBER thing, which reduces confusion. Of course they had to add the confusion back by making an ARMv7-m (cortex-MNUMBER) and the ARMv7-a (Cortex-ANUMBER) which are very different families, one is for heavy loads, desktops, laptops, etc the other is for microcontrollers, clocks and blinking lights on a coffee maker and things like that. google beagleboard (Cortex-A) and the stm32 value line discovery board (Cortex-M) to get a feel for the differences. Or even the open-rd.org board which uses multiple cores at more than a gigahertz or the newer tegra 2 from nvidia, same deal super scaler, muti core, multi gigahertz. A cortex-m barely brakes the 100MHz barrier and has memory measured in kbytes although it probably runs of a battery for months if you wanted it to where a cortex-a not so much.

sorry for the very long post, hope it is useful.

you can use this for lists of the same length

def lstsum(a, b):
    c=0
    pos = 0
for element in a:
   c+= element*b[pos]
   pos+=1
return c

Not for the questioner, but for all others, which are interested: See: How to define Typescript Map of key value pair. where key is a number and value is an array of objects

The solution is therefore:

let yourVar: Map<YourKeyType, YourValueType>;
// now you can use it:
yourVar = new Map<YourKeyType, YourValueType>();
yourVar[YourKeyType] = <YourValueType> yourValue;

Cheers!

If you are only concerned with the constant True, a simple sum is fine. However, keep in mind that in Python other values evaluate as True as well. A more robust solution would be to use the bool builtin:

>>> l = [1, 2, True, False]
>>> sum(bool(x) for x in l)
3

UPDATE: Here's another similarly robust solution that has the advantage of being more transparent:

>>> sum(1 for x in l if x)
3

P.S. Python trivia: True could be true without being 1. Warning: do not try this at work!

>>> True = 2
>>> if True: print('true')
... 
true
>>> l = [True, True, False, True]
>>> sum(l)
6
>>> sum(bool(x) for x in l)
3
>>> sum(1 for x in l if x)
3

Much more evil:

True = False
