I once had the same problem, and then I searched and found this and it worked for me:

I had got some of the boxes unchecked, so I checked them again, then it worked. Just go to

Windows > Preferences > Java > Editor > Content Assist > Advanced

and check the boxes which you want .

1. window->preferences->java->Editor->Contest Assist
   
2. Enter in Auto activation triggers for java:
   abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ._
   
3. Apply and Close
   

other method:
type initial letter then ctrl+spacebar for auto-complete options.

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy MM dd");
String text = date.toString(formatter);
LocalDate date = LocalDate.parse(text, formatter);

I believe this might help, you may need to use some sort of localdate variation instead of instant

Here is the simplest way I found,

num <- c(5665,1615,5154,65564,69895646)

num <- sort(num, decreasing = F)

tail(num, 1)                           # Highest number
head(tail(num, 2),1)                   # Second Highest number
head(tail(num, 3),1)                   # Third Highest number
head(tail(num, n),1)                   # Generl equation for finding nth Highest number

for key, value in d.iteritems():
    print key, '\t', value

datetime.datetime.strptime has problems with timezone parsing. Have a look at the dateutil package:

>>> from dateutil import parser
>>> parser.parse("Tue May 08 15:14:45 +0800 2012")
datetime.datetime(2012, 5, 8, 15, 14, 45, tzinfo=tzoffset(None, 28800))

PreparedStatement alone does not help you if you are still concatenating Strings.

For instance, one rogue attacker can still do the following:

• call a sleep function so that all your database connections will be busy, therefore making your application unavailable
• extracting sensitive data from the DB
• bypassing the user authentication

Not only SQL, but even JPQL or HQL can be compromised if you are not using bind parameters.

Bottom line, you should never use string concatenation when building SQL statements. Use a dedicated API for that purpose, like JPA Criteria API.

Another C# version with lazy generation of the combination indices. This version maintains a single array of indices to define a mapping between the list of all values and the values for the current combination, i.e. constantly uses O(k) additional space during the entire runtime. The code generates individual combinations, including the first one, in O(k) time.

public static IEnumerable<T[]> Combinations<T>(this T[] values, int k)
{
    if (k < 0 || values.Length < k)
        yield break; // invalid parameters, no combinations possible

    // generate the initial combination indices
    var combIndices = new int[k];
    for (var i = 0; i < k; i++)
    {
        combIndices[i] = i;
    }

    while (true)
    {
        // return next combination
        var combination = new T[k];
        for (var i = 0; i < k; i++)
        {
            combination[i] = values[combIndices[i]];
        }
        yield return combination;

        // find first index to update
        var indexToUpdate = k - 1;
        while (indexToUpdate >= 0 && combIndices[indexToUpdate] >= values.Length - k + indexToUpdate)
        {
            indexToUpdate--;
        }

        if (indexToUpdate < 0)
            yield break; // done

        // update combination indices
        for (var combIndex = combIndices[indexToUpdate] + 1; indexToUpdate < k; indexToUpdate++, combIndex++)
        {
            combIndices[indexToUpdate] = combIndex;
        }
    }
}

Test code:

foreach (var combination in new[] {'a', 'b', 'c', 'd', 'e'}.Combinations(3))
{
    System.Console.WriteLine(String.Join(" ", combination));
}

Output:

a b c
a b d
a b e
a c d
a c e
a d e
b c d
b c e
b d e
c d e

You can also create the application.properties file manually.

SpringApplication will load properties from application.properties files in the following locations and add them to the Spring Environment:

• A /config subdirectory of the current directory.
• The current directory
• A classpath /config package
• The classpath root

The list is ordered by precedence (properties defined in locations higher in the list override those defined in lower locations). (From the Spring boot features external configuration doc page)

So just go ahead and create it

The following query can be used to detemine tablespace and other params:

select df.tablespace_name "Tablespace",
       totalusedspace "Used MB",
       (df.totalspace - tu.totalusedspace) "Free MB",
       df.totalspace "Total MB",
       round(100 * ( (df.totalspace - tu.totalusedspace)/ df.totalspace)) "Pct. Free"
  from (select tablespace_name,
               round(sum(bytes) / 1048576) TotalSpace
          from dba_data_files 
         group by tablespace_name) df,
       (select round(sum(bytes)/(1024*1024)) totalusedspace,
               tablespace_name
          from dba_segments 
         group by tablespace_name) tu
 where df.tablespace_name = tu.tablespace_name 
   and df.totalspace <> 0;

Source: https://community.oracle.com/message/1832920

For your case if you want to know the partition name and it's size just run this query:

select owner,
       segment_name,
       partition_name,
       segment_type,
       bytes / 1024/1024 "MB" 
  from dba_segments 
 where owner = <owner_name>;

Here is a solution using the plyr package.

The following line of code essentially tells ddply to first group your data by Group, and then within each group returns a subset where the Score equals the maximum score in that group.

library(plyr)
ddply(data, .(Group), function(x)x[x$Score==max(x$Score), ])

  Group Score Info
1     1     3    c
2     2     4    d

And, as @SachaEpskamp points out, this can be further simplified to:

ddply(df, .(Group), function(x)x[which.max(x$Score), ])

(which also has the advantage that which.max will return multiple max lines, if there are any).

In Python you may use the in operator. You can do stuff like this:

>>> "c" in "abc"
True

Taking this further, you can check for complex structures, like tuples:

>>> (2, 4, 8) in ((1, 2, 3), (2, 4, 8))
True

You can do this without modifying the html. http://jsfiddle.net/8JwhZ/1085/

<div class="title">
<span>Cumulative performance</span>
<span>20/02/2011</span>
</div>

.title span:nth-of-type(1) { float:right }
.title span:nth-of-type(2) { float:left }

I have encountered such a problem when grouping object, i always resolved them by a simple way: perform a custom filter using a java.util.Set to remove duplicate object with whatever attribute of your choice as bellow

Set<String> uniqueNames = new HashSet<>();
Map<String, String> phoneBook = people
                  .stream()
                  .filter(person -> person != null && !uniqueNames.add(person.getName()))
                  .collect(toMap(Person::getName, Person::getAddress));

Hope this helps anyone having the same problem !

Some reading to get you started on character encodings: Joel on Software: The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)

By the way - ASP.NET has nothing to do with it. Encodings are universal.

The best thing is probably to create a variable that holds your binaries:

binaries=code1 code2

Then use that in the all-target, to avoid repeating:

all: clean $(binaries)

Now, you can use this with the clean-target, too, and just add some globs to catch object files and stuff:

.PHONY: clean

clean:
    rm -f $(binaries) *.o

Note use of the .PHONY to make clean a pseudo-target. This is a GNU make feature, so if you need to be portable to other make implementations, don't use it.

I had the same issue in my project. Later on found that third-party (fmdb for SQLite) file used in project contained Info.plist.

Simply deleting the Info.plist file worked for me!

Close to what is already posted, but without the redundant parameter:

class String
    def true?
        self.to_s.downcase == "true"
    end
end

usage:

do_stuff = "true"

if do_stuff.true?
    #do stuff
end

$.getJSON is an asynchronous request, meaning the code will continue to run even though the request is not yet done. You should trigger the second request when the first one is done, one of the choices you seen already in ComFreek's answer.

Alternatively you could use jQuery's $.when/.then(), similar to this:

var input = "netuetamundis";  var sID;  $(document).ready(function () {     $.when($.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/" + input + "?api_key=API_KEY_HERE", function () {         obj = name;         sID = obj.id;         console.log(sID);     })).then(function () {         $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function (stats) {             console.log(stats);         });     }); }); 

This would be more open for future modification and separates out the responsibility for the first call to know about the second call.

The first call can simply complete and do it's own thing not having to be aware of any other logic you may want to add, leaving the coupling of the logic separated.

strace lists all system calls done by the process it's applied to. If you don't know what system calls mean, you won't be able to get much mileage from it.

Nevertheless, if your problem involves files or paths or environment values, running strace on the problematic program and redirecting the output to a file and then grepping that file for your path/file/env string may help you see what your program is actually attempting to do, as distinct from what you expected it to.

Style the td and th instead

td, th {
    border: 1px solid black;
}

And also to make it so there is no spacing between cells use:

table {
    border-collapse: collapse;
}

(also note, you have border-style: none; which should be border-style: solid;)

See an example here: http://jsfiddle.net/KbjNr/

If you start out with:

let array = [
    {name: "malcom", dogType: "four-legged"},
    {name: "peabody", dogType: "three-legged"},
    {name: "pablo", dogType: "two-legged"}
];

And you want a set of, say, names, you would do:

let namesSet = new Set(array.map(item => item.name));

Concept Solution:br.read() returns particular character's int value so loop continue's until we won't get -1 as int value and Hence up to there it prints br.readLine() which returns a line into String form.

    //Way 1:
    while(br.read()!=-1)
    {
      //continues loop until we won't get int value as a -1
      System.out.println(br.readLine());
    }

    //Way 2:
    while((line=br.readLine())!=null)
    {
      System.out.println(line);
    }

    //Way 3:
    for(String line=br.readLine();line!=null;line=br.readLine())
    {
      System.out.println(line);
    }

Way 4: It's an advance way to read file using collection and arrays concept How we iterate using for each loop. check it here http://www.java67.com/2016/01/how-to-use-foreach-method-in-java-8-examples.html

Instead of foreach(), use a for() loop with a numeric index.

It's a long time since the question was posted, but I experienced the same issue in a similar scenario. I have a console application and I was consuming a web service and our IIS server where the webservice was placed has windows authentication (NTLM) enabled.

I followed this link and that fixed my problem. Here's the sample code for App.config:

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="Service1Soap">
                <security mode="TransportCredentialOnly">
                    <transport clientCredentialType="Ntlm" proxyCredentialType="None"
                        realm=""/>
                    <message clientCredentialType="UserName" algorithmSuite="Default"/>
                </security>
            </binding>
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://localhost/servicename/service1.asmx" 
            binding="basicHttpBinding" bindingConfiguration="ListsSoap"/>
    </client>
</system.serviceModel>

The settings which has been advised to change in @Diego's accepted answer might be good if you want to set this option permanently for all future query sessions that you open within SQL Server Management Studio(SSMS). This is usually not the case. Also, changing this setting requires restarting SQL Server Management Studio (SSMS) application. This is again a 'not-so-nice' experience if you've many unsaved open query session windows and you are in the middle of some debugging.

SQL Server gives a much slick option of changing it on per session basis which is very quick, handy and convenient. I'm detailing the steps below using query options window:

1. Right click in query editor window > Click Query Options... at the bottom of the context menu as shown below:

2. Select Results > Grid in the left navigation pane. Check the Include column headers when copying or saving the results check box in right pane as shown below:

That's it. Your current session will honour your settings with immediate effect without restarting SSMS. Also, this setting won't be propagated to any future session. Effectively changing this setting on a per session basis is much less noisy.

I am quite late, but this will also work, and will help others:

a = [1,1,1,1,2,2,2,2,3,3,4,5,5]
freq_list = []
a_l = list(set(a))

for x in a_l:
    freq_list.append(a.count(x))


print 'Freq',freq_list
print 'number',a_l

will produce this..

Freq  [4, 4, 2, 1, 2]
number[1, 2, 3, 4, 5]

You can solve it very easily, just wrap that iframe in wrapper, and track clicks on it.

Like this:

<div id="iframe_id_wrapper"> <iframe id="iframe_id" src="http://something.com"></iframe> </div>

And disable pointer events on iframe itself.

#iframe_id { pointer-events: none; }

After this changes your code will work like expected.

$('#iframe_id_wrapper').click(function() { //run function that records clicks });

declare @ModelID uniqueidentifer

--make sure to use brackets
set @ModelID = (select modelid from models
where areaid = 'South Coast')

select @ModelID

Davids, I had the exact same problem as you. MVC is not intuitive and it seems when they designed it the kiddos didn't understand the purpose or importance of an intuitive querystring system for MVC.

Querystrings are not set in the routes at all (RouteConfig). They are add-on "extra" parameters to Actions in the Controller. This is very confusing as the Action parameters are designed to process BOTH paths AND Querystrings. If you added parameters and they did not work, add a second one for the querystring as so:

This would be your action in your Controller class that catches the ID (which is actually just a path set in your RouteConfig file as a typical default path in MVC):

public ActionResult Hello(int id)

But to catch querystrings an additional parameter in your Controller needs to be the added (which is NOT set in your RouteConfig file, by the way):

public ActionResult Hello(int id, string start, string end)

This now listens for "/Hello?start=&end=" or "/Hello/?start=&end=" or "/Hello/45?start=&end=" assuming the "id" is set to optional in the RouteConfig.cs file.

If you wanted to create a "custom route" in the RouteConfig file that has no "id" path, you could leave off the "id" or other parameter after the action in that file. In that case your parameters in your Action method in the controller would process just querystrings.

I found this extremely confusing myself so you are not alone! They should have designed a simple way to add querystring routes for both specific named strings, any querystring name, and any number of querystrings in the RouteConfig file configuration design. By not doing that it leaves the whole use of querystrings in MVC web applications as questionable, which is pretty bizarre since querystrings have been a stable part of the World Wide Web since the mid-1990's. :(

If you have more than the last leaf directory to be created, you can either run a separate ssh ... mkdir -p first, or use the --rsync-path trick as explained here :

rsync -a --rsync-path="mkdir -p /tmp/x/y/z/ && rsync" $source user@remote:/tmp/x/y/z/

Or use the --relative option as suggested by Tony. In that case, you only specify the root of the destination, which must exist, and not the directory structure of the source, which will be created:

rsync -a --relative /new/x/y/z/ user@remote:/pre_existing/dir/

This way, you will end up with /pre_existing/dir/new/x/y/z/

And if you want to have "y/z/" created, but not inside "new/x/", you can add ./ where you want --relativeto begin:

rsync -a --relative /new/x/./y/z/ user@remote:/pre_existing/dir/

would create /pre_existing/dir/y/z/.

There may be situations when df.reset_index() cannot be used (e.g., when you need the index, too). In this case, use index.get_level_values() to access index values directly:

df['Trial'] = df.index.get_level_values(0)
df['measurement'] = df.index.get_level_values(1)

This will assign index values to individual columns and keep the index.

See the docs for further info.

It's even easier than everything suggested above. Data attributes in MVC which include dashes (-) are catered for with the use of underscore (_).

<%= Html.ActionLink("« Previous", "Search",
 new { keyword = Model.Keyword, page = Model.currPage - 1},
 new { @class = "prev", data_details = "Some Details"   })%>

I see JohnnyO already mentioned this.

Another alternative is to use virtualenvwrapper to manage your virtual environments. It appears that once the virtualenvwrapper script is activated, pycharm can use that and then the simple workon command will be available from the pycharm console and present you with the available virtual environments:

kevin@debian:~/Development/django-tutorial$ workon
django-tutorial
FlaskHF
SQLAlchemy
themarkdownapp
kevin@debian:~/Development/django-tutorial$ workon django-tutorial
(django-tutorial)kevin@debian:~/Development/django-tutorial$ 

For example if you navigate from viewControllerB to viewControllerA then in your viewControllerA below delegate will call and data will share.

@IBAction func unWindSeague (_ sender : UIStoryboardSegue) {
        if sender.source is ViewControllerB  {
            if let _ = sender.source as? ViewControllerB {
                self.textLabel.text = "Came from B = B->A , B exited"
            }
            
        }

}

• Unwind Seague Source View Controller ( You Need to connect Exit Button to VC’s exit icon and connect it to unwindseague:

• Unwind Seague Completed -> TextLabel of viewControllerA is Changed.

Just add remove_button_css as class to your button tag. You can verify the code for Link 1

.remove_button_css { 
  outline: none;
  padding: 5px; 
  border: 0px; 
  box-sizing: none; 
  background-color: transparent; 
}

Extra Styles Edit

Add color: #337ab7; and :hover and :focus to match OOTB (bootstrap3)

.remove_button_css:focus,
.remove_button_css:hover {
    color: #23527c;
    text-decoration: underline;
}

As the message says, you have a task which threw an unhandled exception.

Turn on Break on All Exceptions (Debug, Exceptions) and rerun the program.
This will show you the original exception when it was thrown in the first place.

(comment appended): In VS2015 (or above). Select Debug > Options > Debugging > General and unselect the "Enable Just My Code" option.

I guess there's no such feature in postman as to run concurrent tests.

If i were you i would consider Apache jMeter which is used exactly for such scenarios.

Regarding Postman, the only thing that could more or less meet your needs is - Postman Runner. There you can specify the details:

• number of iterations,
• upload csv file with data for different test runs, etc.

The runs won't be concurrent, only consecutive.

Hope that helps. But do consider jMeter (you'll love it).

If you are looking for the amount of time that the associated thread has spent running code inside the application.
You can use ProcessThread.UserProcessorTime Property which you can get under System.Diagnostics namespace.

TimeSpan startTime= Process.GetCurrentProcess().Threads[i].UserProcessorTime; // i being your thread number, make it 0 for main
//Write your function here
TimeSpan duration = Process.GetCurrentProcess().Threads[i].UserProcessorTime.Subtract(startTime);

Console.WriteLine($"Time caluclated by CurrentProcess method: {duration.TotalSeconds}"); // This syntax works only with C# 6.0 and above

Note: If you are using multi threads, you can calculate the time of each thread individually and sum it up for calculating the total duration.

Do

npm install

to install Grunt locally in ./node_modules (and everything else specified in the package.json file)

Before you set your routes, add the code:

app.all('*', function(req, res, next) {
    setTimeout(function() {
        next();
    }, 120000); // 120 seconds
});

Ruby has no pre/post increment/decrement operator. For instance, x++ or x-- will fail to parse. More importantly, ++x or --x will do nothing! In fact, they behave as multiple unary prefix operators: -x == ---x == -----x == ...... To increment a number, simply write x += 1.

Taken from "Things That Newcomers to Ruby Should Know " (archive, mirror)

That explains it better than I ever could.

EDIT: and the reason from the language author himself (source):

1. ++ and -- are NOT reserved operator in Ruby.
2. C's increment/decrement operators are in fact hidden assignment. They affect variables, not objects. You cannot accomplish assignment via method. Ruby uses +=/-= operator instead.
3. self cannot be a target of assignment. In addition, altering the value of integer 1 might cause severe confusion throughout the program.

Your code works fine, except that the barplot is ordered from low to high. When you want to order the bars from high to low, you will have to add a -sign before value:

ggplot(corr.m, aes(x = reorder(miRNA, -value), y = value, fill = variable)) + 
  geom_bar(stat = "identity")

which gives:

Used data:

corr.m <- structure(list(miRNA = structure(c(5L, 2L, 3L, 6L, 1L, 4L), .Label = c("mmu-miR-139-5p", "mmu-miR-1983", "mmu-miR-301a-3p", "mmu-miR-5097", "mmu-miR-532-3p", "mmu-miR-96-5p"), class = "factor"),
                         variable = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = "pos", class = "factor"),
                         value = c(7L, 75L, 70L, 5L, 10L, 47L)),
                    class = "data.frame", row.names = c("1", "2", "3", "4", "5", "6"))

this code will work ,

.navbar .navbar-nav > li .navbar-item ,
.navbar .navbar-brand{
                       color: red;
                      }

paste in your css and run if you have a element below

<li>@Html.ActionLink("Login", "Login", "Home", new { area = "" },
 new { @class = "navbar-item" })</li>

<li> <button class="navbar-item">hi</button></li>

FormulaR1C1 has the same behavior as Formula, only using R1C1 style annotation, instead of A1 annotation. In A1 annotation you would use:

Worksheets("Sheet1").Range("A5").Formula = "=A4+A10"

In R1C1 you would use:

Worksheets("Sheet1").Range("A5").FormulaR1C1 = "=R4C1+R10C1"

It doesn't act upon row 1 column 1, it acts upon the targeted cell or range. Column 1 is the same as column A, so R4C1 is the same as A4, R5C2 is B5, and so forth.

The command does not change names, the targeted cell changes. For your R2C3 (also known as C2) example :

Worksheets("Sheet1").Range("C2").FormulaR1C1 = "=your formula here"

Specify complete path and grant proper permission to scriptfile. I tried following script file to run through cron:

#!/bin/bash
/bin/mkdir /scratch/ofsaaweb/CHEF_FICHOME/ficdb/bin/crondir

And crontab command is

* * * * * /bin/bash /scratch/ofsaaweb/CHEF_FICHOME/ficdb/bin/test.sh

It worked for me.

The whole thing to em is, that the size is relative to the base. So I would say you could keep the font sizes by altering the base.

Example: If you base is 16px, and p is .75em (which is 12px) you would have to raise the base to about 20px. In this case p would then equal about 15px which is the minimum I personally require for mobile phones.

Steve Ebersole & other members,
Would you kindly explain the reason for an id with a larger gap(by default 50)? I am using Hibernate 4.2.15 and found the following code in org.hibernate.id.enhanced.OptimizerFactory cass.

if ( lo > maxLo ) {
   lastSourceValue = callback.getNextValue();
   lo = lastSourceValue.eq( 0 ) ? 1 : 0;
   hi = lastSourceValue.copy().multiplyBy( maxLo+1 ); 
}  
value = hi.copy().add( lo++ );

Whenever it hits the inside of the if statement, hi value is getting much larger. So, my id during the testing with the frequent server restart generates the following sequence ids:
1, 2, 3, 4, 19, 250, 251, 252, 400, 550, 750, 751, 752, 850, 1100, 1150.

I know you already said it didn't conflict with the spec, but I believe this will be very unexpected situation for most developers.

Anyone's input will be much helpful.

UPDATE: ne1410s: Thanks for the edit.
cfrick: OK. I will do that. It was my first post here and wasn't sure how to use it.

Now, I understood better why maxLo was used for two purposes: Since the hibernate calls the DB sequence once, keep increase the id in Java level, and saves it to the DB, the Java level id value should consider how much was changed without calling the DB sequence when it calls the sequence next time.

For example, sequence id was 1 at a point and hibernate entered 5, 6, 7, 8, 9 (with allocationSize = 5). Next time, when we get the next sequence number, DB returns 2, but hibernate needs to use 10, 11, 12... So, that is why "hi = lastSourceValue.copy().multiplyBy( maxLo+1 )" is used to get a next id 10 from the 2 returned from the DB sequence. It seems only bothering thing was during the frequent server restart and this was my issue with the larger gap.

So, when we use the SEQUENCE ID, the inserted id in the table will not match with the SEQUENCE number in DB.

To suppress output, use redirection to NUL.

There are two kinds of output that console commands use:

• standard output, or stdout,

• standard error, or stderr.

Of the two, stdout is used more often, both by internal commands, like copy, and by console utilities, or external commands, like find and others, as well as by third-party console programs.

>NUL suppresses the standard output and works fine e.g. for suppressing the 1 file(s) copied. message of the copy command. An alternative syntax is 1>NUL. So,

COPY file1 file2 >NUL

or

COPY file1 file2 1>NUL

or

>NUL COPY file1 file2

or

1>NUL COPY file1 file2

suppresses all of COPY's standard output.

To suppress error messages, which are typically printed to stderr, use 2>NUL instead. So, to suppress a File Not Found message that DEL prints when, well, the specified file is not found, just add 2>NUL either at the beginning or at the end of the command line:

DEL file 2>NUL

or

2>NUL DEL file

Although sometimes it may be a better idea to actually verify whether the file exists before trying to delete it, like you are doing in your own solution. Note, however, that you don't need to delete the files one by one, using a loop. You can use a single command to delete the lot:

IF EXIST "%scriptDirectory%*.noext" DEL "%scriptDirectory%*.noext"

Keeping your commands short will make them easier to remember:

git log --graph --oneline

Non-recursively List Only Directories

future.utils allows for python 2 and 3 compatibility.

# Python 2 and 3: option 3
from future.utils import iteritems
heights = {'man': 185,'lady': 165}
for (key, value) in iteritems(heights):
    print(key,value)

>>> ('lady', 165)
>>> ('man', 185)

I got this error when I had my button in the GridView in an UpdatePanel... deubbing my code I found that the above error is caused because of another internal error "A potentially dangerous Request.Form value was detected from the client"

Finally I figured out that one of my TextBoxes on the page has XML/HTML content and this in-turn causing above error when I removed the xml/HTML and tested the button click ... it worked as expected.

There's no way to specify a StringComparer at the point where you try to get a value. If you think about it, "foo".GetHashCode() and "FOO".GetHashCode() are totally different so there's no reasonable way you could implement a case-insensitive get on a case-sensitive hash map.

You can, however, create a case-insensitive dictionary in the first place using:-

var comparer = StringComparer.OrdinalIgnoreCase;
var caseInsensitiveDictionary = new Dictionary<string, int>(comparer);

Or create a new case-insensitive dictionary with the contents of an existing case-sensitive dictionary (if you're sure there are no case collisions):-

var oldDictionary = ...;
var comparer = StringComparer.OrdinalIgnoreCase;
var newDictionary = new Dictionary<string, int>(oldDictionary, comparer);

This new dictionary then uses the GetHashCode() implementation on StringComparer.OrdinalIgnoreCase so comparer.GetHashCode("foo") and comparer.GetHashcode("FOO") give you the same value.

Alternately, if there are only a few elements in the dictionary, and/or you only need to lookup once or twice, you can treat the original dictionary as an IEnumerable<KeyValuePair<TKey, TValue>> and just iterate over it:-

var myKey = ...;
var myDictionary = ...;
var comparer = StringComparer.OrdinalIgnoreCase;
var value = myDictionary.FirstOrDefault(x => String.Equals(x.Key, myKey, comparer)).Value;

Or if you prefer, without the LINQ:-

var myKey = ...;
var myDictionary = ...;
var comparer = StringComparer.OrdinalIgnoreCase;
int? value;
foreach (var element in myDictionary)
{
  if (String.Equals(element.Key, myKey, comparer))
  {
    value = element.Value;
    break;
  }
}

This saves you the cost of creating a new data structure, but in return the cost of a lookup is O(n) instead of O(1).

You can combine filter with the text.

In Windows 7 (it should work for Windows 8 also, but I haven't tested it):

Go to a command prompt

Steps to go to a command prompt:

1. Click Start Menu
2. In Search Box, type "cmd" (without quotes)
3. Open cmd.exe

In cmd, type this command

wmic /namespace:\\root\cimv2 path win32_product where "name like '%%.NET%%'" get version

This gives the latest version of NET Framework installed.

One can also try Raymond.cc Utilties for the same.

I do not own the credit for this, but I just have to share it. This regex will get numbers from a string, including decimal points/places, as well as commas:

/((?:[0-9]+,)*[0-9]+(?:\.[0-9]+)?)/

If your server certificated file is not trusted, (for example, you may generate the keystore by yourself with keytool command in java), you should add the extra option rejectUnauthorized

var socket = io.connect('https://localhost', {rejectUnauthorized: false});

If I remember correctly, you'll need to set the netbeans_jdkhome property in your netbeans config file. Should be in your etc/netbeans.conf file.

The answer here is not clear, so I wanted to add more detail.

Using the link provided above, I performed the following step.

In my XML config manager I changed the "Provider" to SQLOLEDB.1 rather than SQLNCLI.1. This got me past this error.

This information is available at the link the OP posted in the Answer.

The link the got me there: http://social.msdn.microsoft.com/Forums/en-US/sqlintegrationservices/thread/fab0e3bf-4adf-4f17-b9f6-7b7f9db6523c/

why don't you do it like this:

in the pages:

<html>
   <head></head>
   <body>
      <?php $page = 'one'; include('navigation.php'); ?>
   </body>
</html>

in the navigation.php

<div id="nav">
   <ul>
      <li>
          <a <?php echo ($page == 'one') ? "class='active'" : ""; ?> 
                 href="index1.php">Tab1</a>/</li>
      <li>
          <a <?php echo ($page == 'two') ? "class='active'" : ""; ?> 
                  href="index2.php">Tab2</a>/</li>
      <li>
          <a <?php echo ($page == 'three') ? "class='active'" : ""; ?> 
                  href="index3.php">Tab3</a>/</li>
   </ul>
</div>

You will actually be able to control where in the page you are putting the navigation and what parameters you are passing to it.

Later edit: fixed syntax error.

If you want to avoid any extra modules, you can use the subprocess module to run

ssh [host] [command]

and capture the output.

Try something like:

process = subprocess.Popen("ssh example.com ls", shell=True,
    stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
output,stderr = process.communicate()
status = process.poll()
print output

To deal with usernames and passwords, you can use subprocess to interact with the ssh process, or you could install a public key on the server to avoid the password prompt.

This should be enough to answer your question: http://docs.oracle.com/javase/tutorial/java/IandI/objectclass.html

The equals() method compares two objects for equality and returns true if they are equal. The equals() method provided in the Object class uses the identity operator (==) to determine whether two objects are equal. For primitive data types, this gives the correct result. For objects, however, it does not. The equals() method provided by Object tests whether the object references are equal—that is, if the objects compared are the exact same object.

To test whether two objects are equal in the sense of equivalency (containing the same information), you must override the equals() method.

(Partial quote - click through to read examples.)

You should be using the dirpath which you call root. The dirnames are supplied so you can prune it if there are folders that you don't wish os.walk to recurse into.

import os
result = [os.path.join(dp, f) for dp, dn, filenames in os.walk(PATH) for f in filenames if os.path.splitext(f)[1] == '.txt']

Edit:

After the latest downvote, it occurred to me that glob is a better tool for selecting by extension.

import os
from glob import glob
result = [y for x in os.walk(PATH) for y in glob(os.path.join(x[0], '*.txt'))]

Also a generator version

from itertools import chain
result = (chain.from_iterable(glob(os.path.join(x[0], '*.txt')) for x in os.walk('.')))

Edit2 for Python 3.4+

from pathlib import Path
result = list(Path(".").rglob("*.[tT][xX][tT]"))

If the goal is to delete the objects a and b themselves (which appears to be the case), forming the list [a, b] is not helpful. Instead, one should keep a list of strings used as the names of those objects. These allow one to delete the objects in a loop, by accessing the globals() dictionary.

c = ['a', 'b']
# create and work with a and b    
for i in c:
    del globals()[i]

The dword ptr part is called a size directive. This page explains them, but it wasn't possible to direct-link to the correct section.

Basically, it means "the size of the target operand is 32 bits", so this will bitwise-AND the 32-bit value at the address computed by taking the contents of the ebp register and subtracting four with 0.

Let's say you are writing a test case for a negative flow where the code being tested should raise an exception.

try{
   bizMethod(badData);
   fail(); // FAIL when no exception is thrown
} catch (BizException e) {
   assert(e.errorCode == THE_ERROR_CODE_U_R_LOOKING_FOR)
}

It's case-sensitive, just make sure created branch and push to branch both are in same capital.

Example:

git checkout -b "TASK-135-hello-world"

WRONG way of doing:

git push origin task-135-hello-world     #FATAL: task-135-hello-world cannot be resolved to branch

CORRECT way of doing:

git push origin TASK-135-hello-world

if you want to get the whole period:

    from sqlalchemy import and_, func

    query = DBSession.query(User).filter(and_(func.date(User.birthday) >= '1985-01-17'),\
                                              func.date(User.birthday) <= '1988-01-17'))

That means range: 1985-01-17 00:00 - 1988-01-17 23:59

Try finding the Service running on the PID that is blocking the service from Task manager->Services

In case this isn't of help go to Task Manager->Services Go to the Services button on bottom right of window and stop the Web Deployment Agent Service. Retry starting Apache . That might solve the problem.

In NumPy it is quite simple

import numpy as np
P=2.45
S=[22, 33, 45.6, 21.6, 51.8]
SP = P*np.array(S)

I recommend taking a look at the NumPy tutorial for an explanation of the full capabilities of NumPy's arrays:

    if 'Unnamed' in col:
        #del df[col]
        print col
        try:
            df.drop(col, axis=1, inplace=True)
        except Exception:
            pass

    pip install pywin32

    python Scripts/pywin32_postinstall.py -install

I know I'm reviving an old thread, but I just had this problem and this was the only way to solve it.

I found a generic and simple way to do that. In my class I created a method that returns the generic type according to it's position in the class definition. Let's assume a class definition like this:

public class MyClass<A, B, C> {

}

Now let's create some attributes to persist the types:

public class MyClass<A, B, C> {

    private Class<A> aType;

    private Class<B> bType;

    private Class<C> cType;

// Getters and setters (not necessary if you are going to use them internally)

    } 

Then you can create a generic method that returns the type based on the index of the generic definition:

   /**
     * Returns a {@link Type} object to identify generic types
     * @return type
     */
    private Type getGenericClassType(int index) {
        // To make it use generics without supplying the class type
        Type type = getClass().getGenericSuperclass();

        while (!(type instanceof ParameterizedType)) {
            if (type instanceof ParameterizedType) {
                type = ((Class<?>) ((ParameterizedType) type).getRawType()).getGenericSuperclass();
            } else {
                type = ((Class<?>) type).getGenericSuperclass();
            }
        }

        return ((ParameterizedType) type).getActualTypeArguments()[index];
    }

Finally, in the constructor just call the method and send the index for each type. The complete code should look like:

public class MyClass<A, B, C> {

    private Class<A> aType;

    private Class<B> bType;

    private Class<C> cType;


    public MyClass() {
      this.aType = (Class<A>) getGenericClassType(0);
      this.bType = (Class<B>) getGenericClassType(1);
      this.cType = (Class<C>) getGenericClassType(2);
    }

   /**
     * Returns a {@link Type} object to identify generic types
     * @return type
     */
    private Type getGenericClassType(int index) {

        Type type = getClass().getGenericSuperclass();

        while (!(type instanceof ParameterizedType)) {
            if (type instanceof ParameterizedType) {
                type = ((Class<?>) ((ParameterizedType) type).getRawType()).getGenericSuperclass();
            } else {
                type = ((Class<?>) type).getGenericSuperclass();
            }
        }

        return ((ParameterizedType) type).getActualTypeArguments()[index];
    }
}

Make variables are not exported into the environment of processes make invokes... by default. However you can use make's export to force them to do so. Change:

test: NODE_ENV = test

to this:

test: export NODE_ENV = test

(assuming you have a sufficiently modern version of GNU make >= 3.77 ).

Here's one way you can do this:

var escape = document.createElement('textarea');
function escapeHTML(html) {
    escape.textContent = html;
    return escape.innerHTML;
}

function unescapeHTML(html) {
    escape.innerHTML = html;
    return escape.textContent;
}

Here's a demo.

In a nutshell:

• CMD sets default command and/or parameters, which can be overwritten from command line when docker container runs.
• ENTRYPOINT command and parameters will not be overwritten from command line. Instead, all command line arguments will be added after ENTRYPOINT parameters.

If you need more details or would like to see difference on example, there is a blog post that comprehensively compare CMD and ENTRYPOINT with lots of examples - http://goinbigdata.com/docker-run-vs-cmd-vs-entrypoint/

If you want maximum throughput, allowing multiple readers to read and only one writer to write, BCL has something called ReaderWriterLockSlim that should help slim down your code...

You're probably not actually signing the release build of the APK via the signing wizard. You can either build the release APK from the command line with the command:

./gradlew assembleRelease

or you can choose the release variant from the Build Variants view and build it from the GUI:

JQuery .is will test all specified elements and return true if at least one of them matches selector:

if ($(":checkbox[name='choices']", form).is(":checked"))
{
    // one or more checked
}
else
{
    // nothing checked
}

One solution to this problem is to use the Handler.postDelayed() method. Some Google training materials suggest the same solution.

@Override
public void onClick(View v) {
    my_button.setBackgroundResource(R.drawable.icon);

    Handler handler = new Handler(); 
    handler.postDelayed(new Runnable() {
         @Override 
         public void run() { 
              my_button.setBackgroundResource(R.drawable.defaultcard); 
         } 
    }, 2000); 
}

However, some have pointed out that the solution above causes a memory leak because it uses a non-static inner and anonymous class which implicitly holds a reference to its outer class, the activity. This is a problem when the activity context is garbage collected.

A more complex solution that avoids the memory leak subclasses the Handler and Runnable with static inner classes inside the activity since static inner classes do not hold an implicit reference to their outer class:

private static class MyHandler extends Handler {}
private final MyHandler mHandler = new MyHandler();

public static class MyRunnable implements Runnable {
    private final WeakReference<Activity> mActivity;

    public MyRunnable(Activity activity) {
        mActivity = new WeakReference<>(activity);
    }

    @Override
    public void run() {
        Activity activity = mActivity.get();
        if (activity != null) {
            Button btn = (Button) activity.findViewById(R.id.button);
            btn.setBackgroundResource(R.drawable.defaultcard);
        }
    }
}

private MyRunnable mRunnable = new MyRunnable(this);

public void onClick(View view) {
    my_button.setBackgroundResource(R.drawable.icon);

    // Execute the Runnable in 2 seconds
    mHandler.postDelayed(mRunnable, 2000);
}

Note that the Runnable uses a WeakReference to the Activity, which is necessary in a static class that needs access to the UI.

If you install the "cssnext" Post CSS plugin, then you can safely start using the syntax that you want to use right now.

Using cssnext will turn this:

}

Into this:

input:not([type="radio"]):not([type="checkbox"]) {
  /* css here */
}

In bash script, what does #!/bin/bash at the 1st line mean ?

In Linux system, we have shell which interprets our UNIX commands. Now there are a number of shell in Unix system. Among them, there is a shell called bash which is very very common Linux and it has a long history. This is a by default shell in Linux.

When you write a script (collection of unix commands and so on) you have a option to specify which shell it can be used. Generally you can specify which shell it wold be by using Shebang(Yes that's what it's name).

So if you #!/bin/bash in the top of your scripts then you are telling your system to use bash as a default shell.

Now coming to your second question :Is there a difference between #!/bin/bash and #!/bin/sh ?

The answer is Yes. When you tell #!/bin/bash then you are telling your environment/ os to use bash as a command interpreter. This is hard coded thing.

Every system has its own shell which the system will use to execute its own system scripts. This system shell can be vary from OS to OS(most of the time it will be bash. Ubuntu recently using dash as default system shell). When you specify #!/bin/sh then system will use it's internal system shell to interpreting your shell scripts.

Hope this will eliminate your confusions...good luck.

1. Go to the netbeans installation directory
2. Find configuration file [installation-directory]/etc/netbeans.conf
3. towards the end find the line netbeans_jdkhome=...
4. comment this line line using '#'
5. now run netbeans. launcher will find jdk itself (from $JDK_HOME/$JAVA_HOME) environment variable

example:

sudo vim /usr/local/netbeans-8.2/etc/netbeans.conf

The cause of your problems is that you are trying to do a cross-domain call and it fails.

If you're doing localhost development you can make cross-domain calls - I do it all the time.

For Firefox, you have to enable it in your config settings

signed.applets.codebase_principal_support = true

Then add something like this to your XHR open code:

  if (isLocalHost()){
    if (typeof(netscape) != 'undefined' && typeof(netscape.security) != 'undefined'){
      netscape.security.PrivilegeManager.enablePrivilege('UniversalBrowserRead');
    }
  }

For IE, if I remember right, all you have to do is enable the browser's Security setting under "Miscellaneous → Access data sources across domains" to get it to work with ActiveX XHRs.

IE8 and above also added cross-domain capabilities to the native XmlHttpRequest objects, but I haven't played with those yet.

This was driving me bonkers as the .astype() solution above didn't work for me. But I found another way. Haven't timed it or anything, but might work for others out there:

t1 = pd.to_datetime('1/1/2015 01:00')
t2 = pd.to_datetime('1/1/2015 03:30')

print pd.Timedelta(t2 - t1).seconds / 3600.0

...if you want hours. Or:

print pd.Timedelta(t2 - t1).seconds / 60.0

...if you want minutes.

Place the link location in the action="" of a wrapping form tag.

Your first link would be:

<form action="1.html">
    <input type="submit" class="button_active" value="1">
</form>

Instead of using jQuery, use css property text-overflow:ellipsis. It will automatically truncate the string.

.truncated { display:inline-block; 
             max-width:100px; 
             overflow:hidden; 
             text-overflow:ellipsis; 
             white-space:nowrap; 
           }

Try adding parentheses around the row in table1 e.g.

DELETE 
  FROM table1
 WHERE (stn, year(datum)) IN (SELECT stn, jaar FROM table2);

The above is Standard SQL-92 code. If that doesn't work, it could be that your SQL product of choice doesn't support it.

Here's another Standard SQL approach that is more widely implemented among vendors e.g. tested on SQL Server 2008:

MERGE INTO table1 AS t1
   USING table2 AS s1
      ON t1.stn = s1.stn
         AND s1.jaar = YEAR(t1.datum)
WHEN MATCHED THEN DELETE;

For me, Added the following to my server's web.config file:

<system.webServer>
    <httpProtocol>
        <customHeaders>
            <add name="Access-Control-Allow-Origin" value="https://other.domain.com" />
            <add name="Access-Control-Allow-Methods" value="GET,POST,OPTIONS,PUT,DELETE" />
            <add name="Access-Control-Allow-Headers" value="Content-Type,X-Requested-With" />
        </customHeaders>
    </httpProtocol>
<system.webServer>

Simple JavaScript code:

for(var propertyName in myObject) {
   // propertyName is what you want.
   // You can get the value like this: myObject[propertyName]
}

jQuery:

jQuery.each(obj, function(key, value) {
   // key is what you want.
   // The value is in: value
});

Populating a temporary list is like downloading the whole video, whereas using yield is like streaming that video.

This works for me to find queries on any database in the instance. I'm sysadmin on the instance (check your privileges):

SELECT deqs.last_execution_time AS [Time], dest.text AS [Query], dest.*
FROM sys.dm_exec_query_stats AS deqs
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.

Show file and track error

 systemctl status nginx.service

Basically, the difference between the two is that one is written in the old way, while the other is written in the modern way. Personally, I prefer the modern script using the inner, left, outer, right definitions because they are more explanatory and makes the code more readable.

When dealing with inner joins there is no real difference in readability neither, however, it may get complicated when dealing with left and right joins as in the older method you would get something like this:

SELECT * 
FROM table a, table b
WHERE a.id = b.id (+);

The above is the old way how a left join is written as opposed to the following:

SELECT * 
FROM table a 
LEFT JOIN table b ON a.id = b.id;

As you can visually see, the modern way of how the script is written makes the query more readable. (By the way same goes for right joins and a little more complicated for outer joins).

Going back to the boiler plate, it doesn't make a difference to the SQL compiler how the query is written as it handles them in the same way. I've seen a mix of both in Oracle databases which have had many people writing into it, both elder and younger ones. Again, it boils down to how readable the script is and the team you are developing with.

This error can occur even if the name of the function is valid if some mandatory arguments are missing (i.e you did not provide enough arguments).
I got this in an Rcpp context, where I wrote a C++ function with optionnal arguments, and did not provided those arguments in R. It appeared that optionnal arguments from the C++ were seen as mandatory by R. As a result, R could not find a matching function for the correct name but an incorrect number of arguments.

Rcpp Function : SEXP RcppFunction(arg1, arg2=0) {}
R Calls :
RcppFunction(0) raises the error
RcppFunction(0, 0) does not

lvalue means "left value" -- it should be assignable. You cannot change the value of text since it is an array, not a pointer.

Either declare it as char pointer (in this case it's better to declare it as const char*):

const char *text;
if(number == 2) 
    text = "awesome"; 
else 
    text = "you fail";

Or use strcpy:

char text[60];
if(number == 2) 
    strcpy(text, "awesome"); 
else 
    strcpy(text, "you fail");

Use:

h1 {_x000D_
    margin: 0;_x000D_
    position: absolute;_x000D_
    left: 50%;_x000D_
    top: 50%;_x000D_
    transform: translate(-50%, -50%);_x000D_
}_x000D_
.container {_x000D_
    height: 200px;_x000D_
    width: 500px;_x000D_
    position: relative;_x000D_
    border: 1px solid #eee;_x000D_
}

<div class="container">_x000D_
    <h1>Vertical align text</h1>_x000D_
</div>

With this trick, you can align anything if you don't want to make it center add "left:0" to align left.

Generate a github oauth token here and export your github token as an environment variable:

export GITHUB_TOKEN=123

Set git config to use the basic auth url:

git config --global url."https://$GITHUB_TOKEN:[email protected]/".insteadOf "https://github.com/"

Now you can go get your private repo.

Long ago it was impossible to reliably get the list of processes locking a file because Windows simply did not track that information. To support the Restart Manager API, that information is now tracked.

Using from Limited Permission (e.g. IIS)

This call accesses the registry. If the process does not have permission to do so, you will get ERROR_WRITE_FAULT, meaning An operation was unable to read or write to the registry. You could selectively grant permission to your restricted account to the necessary part of the registry. It is more secure though to have your limited access process set a flag (e.g. in the database or the file system, or by using an interprocess communication mechanism such as queue or named pipe) and have a second process call the Restart Manager API.

Granting other-than-minimal permissions to the IIS user is a security risk.

I had the same problem, add this 2 line in your build.gradle the problem will be resolved probably. ;)

@STEVER's answer is satisfactory. However, I thought it may be useful to post a slightly different approach. I use a method called isValue which returns true for all values except null, undefined, NaN, and Infinity. Lumping in NaN with null and undefined is the real benefit of the function for me. Lumping Infinity in with null and undefined is more debatable, but frankly not that interesting for my code because I practically never use Infinity.

The following code is inspired by Y.Lang.isValue. Here is the source for Y.Lang.isValue.

/**
 * A convenience method for detecting a legitimate non-null value.
 * Returns false for null/undefined/NaN/Infinity, true for other values,
 * including 0/false/''
 * @method isValue
 * @static
 * @param o The item to test.
 * @return {boolean} true if it is not null/undefined/NaN || false.
 */
angular.isValue = function(val) {
  return !(val === null || !angular.isDefined(val) || (angular.isNumber(val) && !isFinite(val)));
};

Or as part of a factory

.factory('lang', function () {
  return {
    /**
     * A convenience method for detecting a legitimate non-null value.
     * Returns false for null/undefined/NaN/Infinity, true for other values,
     * including 0/false/''
     * @method isValue
     * @static
     * @param o The item to test.
     * @return {boolean} true if it is not null/undefined/NaN || false.
     */
    isValue: function(val) {
      return !(val === null || !angular.isDefined(val) || (angular.isNumber(val) && !isFinite(val)));
  };
})

When using spark-submit with --master yarn-cluster, the application jar along with any jars included with the --jars option will be automatically transferred to the cluster. URLs supplied after --jars must be separated by commas. That list is included in the driver and executor classpaths

Example :

spark-submit --master yarn-cluster --jars ../lib/misc.jar, ../lib/test.jar --class MainClass MainApp.jar

If you want to change buttons text color (positive, negative, neutral) just add to your custom dialog style:

<item name="colorAccent">@color/accent_color</item>

So, your dialog style must looks like this:

<style name="AlertDialog" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="android:textColor">@android:color/black</item>
    <item name="colorAccent">@color/topeka_accent</item>
</style>

For those using TortoiseSVN, you can accomplish this by using the Repository Browser (it's labeled "Repo-browser" in the context menu.)

Find the branch folder you want to delete, right-click it, and select "Delete."

Enter your commit message, and you're done.

You can also drag and drop the folder from Windows Explorer onto your Visual Studio solution window.

Create a breakpoint as you normally would, right click the red dot and select "condition".

HttpClient is not a class, it is an interface. You cannot use it for development in the way you mean.

As mscdex said NPM comes with the nodejs msi installed file. I happened to just install the node js installer (standalone). To separately add NPM I followed following step

1. Download the latest zip file of NPM from here.
2. Extract it in the same file as that of node js installer.
3. If you have added the directory containing to node js installer to PATH env variable then now even npm should be a recognized command.

we removed a lib folder from the website folder. this was created by a previous installation of typings. this became duplicate. When this was removed it worked!

A simple example, similar to the solutions above. This doesn't require monitoring any process output. The next example uses tail to follow output.

$ echo '#!/bin/bash' > tmp.sh
$ echo 'sleep 30; exit 5' >> tmp.sh
$ chmod +x tmp.sh
$ ./tmp.sh &
[1] 7454
$ pid=$!
$ wait $pid
[1]+  Exit 5                  ./tmp.sh
$ echo $?
5

Use tail to follow process output and quit when the process is complete.

$ echo '#!/bin/bash' > tmp.sh
$ echo 'i=0; while let "$i < 10"; do sleep 5; echo "$i"; let i=$i+1; done; exit 5;' >> tmp.sh
$ chmod +x tmp.sh
$ ./tmp.sh

$ ./tmp.sh > /tmp/tmp.log 2>&1 &

this is a simple way to pad left:

REPLACE(STR(FACT_HEAD.FACT_NO, x, 0), ' ', y)

Where x is the pad number and y is the pad character.

sample:

tl;dr

java.util.Date.from(  // Transfer the moment in UTC, truncating any microseconds or nanoseconds to milliseconds.
    Instant.now() ;   // Capture current moment in UTC, with resolution as fine as nanoseconds.
)

Though there was no point in that code above. Both java.util.Date and Instant represent a moment in UTC, always in UTC. Code above has same effect as:

new java.util.Date()  // Capture current moment in UTC.

No benefit here to using ZonedDateTime. If you already have a ZonedDateTime, adjust to UTC by extracting a Instant.

java.util.Date.from(             // Truncates any micros/nanos.
    myZonedDateTime.toInstant()  // Adjust to UTC. Same moment, same point on the timeline, different wall-clock time.
)

Other Answer Correct

The Answer by ssoltanid correctly addresses your specific question, how to convert a new-school java.time object (ZonedDateTime) to an old-school java.util.Date object. Extract the Instant from the ZonedDateTime and pass to java.util.Date.from().

Data Loss

Note that you will suffer data loss, as Instant tracks nanoseconds since epoch while java.util.Date tracks milliseconds since epoch.

Your Question and comments raise other issues.

Keep Servers In UTC

Your servers should have their host OS set to UTC as a best practice generally. The JVM picks up on this host OS setting as its default time zone, in the Java implementations that I'm aware of.

Specify Time Zone

But you should never rely on the JVM’s current default time zone. Rather than pick up the host setting, a flag passed when launching a JVM can set another time zone. Even worse: Any code in any thread of any app at any moment can make a call to java.util.TimeZone::setDefault to change that default at runtime!

Cassandra Timestamp Type

Any decent database and driver should automatically handle adjusting a passed date-time to UTC for storage. I do not use Cassandra, but it does seem to have some rudimentary support for date-time. The documentation says its Timestamp type is a count of milliseconds from the same epoch (first moment of 1970 in UTC).

ISO 8601

Furthermore, Cassandra accepts string inputs in the ISO 8601 standard formats. Fortunately, java.time uses ISO 8601 formats as its defaults for parsing/generating strings. The Instant class’ toString implementation will do nicely.

Precision: Millisecond vs Nanosecord

But first we need to reduce the nanosecond precision of ZonedDateTime to milliseconds. One way is to create a fresh Instant using milliseconds. Fortunately, java.time has some handy methods for converting to and from milliseconds.

Example Code

Here is some example code in Java 8 Update 60.

ZonedDateTime zdt = ZonedDateTime.now( ZoneId.of( "America/Montreal" ) );
…
Instant instant = zdt.toInstant();
Instant instantTruncatedToMilliseconds = Instant.ofEpochMilli( instant.toEpochMilli() );
String fodderForCassandra = instantTruncatedToMilliseconds.toString();  // Example: 2015-08-18T06:36:40.321Z

Or according to this Cassandra Java driver doc, you can pass a java.util.Date instance (not to be confused with java.sqlDate). So you could make a j.u.Date from that instantTruncatedToMilliseconds in the code above.

java.util.Date dateForCassandra = java.util.Date.from( instantTruncatedToMilliseconds );

If doing this often, you could make a one-liner.

java.util.Date dateForCassandra = java.util.Date.from( zdt.toInstant() );

But it would be neater to create a little utility method.

static public java.util.Date toJavaUtilDateFromZonedDateTime ( ZonedDateTime zdt ) {
    Instant instant = zdt.toInstant();
    // Data-loss, going from nanosecond resolution to milliseconds.
    java.util.Date utilDate = java.util.Date.from( instant ) ;
    return utilDate;

Notice the difference in all this code than in the Question. The Question’s code was trying to adjust the time zone of the ZonedDateTime instance to UTC. But that is not necessary. Conceptually:

ZonedDateTime = Instant + ZoneId

We just extract the Instant part, which is already in UTC (basically in UTC, read the class doc for precise details).

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Yes, you can get exact Keras representation, using pytorch-summary package.

I changed a bit and it worked like this, dumped into one single array, provided all the images are of same dimensions.

png = []

    png.append(misc.imread(image_path))    

im = np.asarray(png)

print 'Importing done...', im.shape

I strongly recommend taking a look at Vuex, it is made for globally accessible data in Vue.

If you only need a few base variables that will never be modified, I would use ES6 imports:

// config.js
export default {
   hostname: 'myhostname'
}

// .vue file
import config from 'config.js'

console.log(config.hostname)

You could also import a json file in the same way, which can be edited by people without code knowledge or imported into SASS.

You can use the :before and :after pseudo-classes to put a multi-layered background on a element.

#divID : before {
    background: url(someImage);
}

#div : after {
    background : url(someotherImage) -10% no-repeat;
}

Just one more alternative using URL

var theUrl = new URL(window.location.href);
theUrl.search = ""; //Remove any params
theUrl //as URL object
theUrl.href //as a string

You can't easily use a range here because the iterator you get from a map refers to a std::pair, where the iterators you would use to insert into a vector refers to an object of the type stored in the vector, which is (if you are discarding the key) not a pair.

I really don't think it gets much cleaner than the obvious:

#include <map>
#include <vector>
#include <string>
using namespace std;

int main() {
    typedef map <string, int> MapType;
    MapType m;  
    vector <int> v;

    // populate map somehow

    for( MapType::iterator it = m.begin(); it != m.end(); ++it ) {
        v.push_back( it->second );
    }
}

which I would probably re-write as a template function if I was going to use it more than once. Something like:

template <typename M, typename V> 
void MapToVec( const  M & m, V & v ) {
    for( typename M::const_iterator it = m.begin(); it != m.end(); ++it ) {
        v.push_back( it->second );
    }
}

i Create new E-mail without any phone number or related E-mail then Turn ON less secure app access that done with me

To further generalize @Alexander's example, outer is relevant in cases where a function must compute itself on each pair of vector values:

vars1<-c(1,2,3)
vars2<-c(10,20,30)
mult_one<-function(var1,var2)
{
   var1*var2
}
outer(vars1,vars2,mult_one)

gives:

> outer(vars1, vars2, mult_one)
     [,1] [,2] [,3]
[1,]   10   20   30
[2,]   20   40   60
[3,]   30   60   90

Both r+ and w+ can read and write to a file. However, r+ doesn't delete the content of the file and doesn't create a new file if such file doesn't exist, whereas w+ deletes the content of the file and creates it if it doesn't exist.

I was having a similar problem. (No problems training with GradientDescent optimizer, but error raised when using to Adam Optimizer, or any other optimizer with its own variables)

Changing to an interactive session solved this problem for me.

Cmd+D from within the Simulator. It'll popup Chrome and from there you can use the Developer Tools.

Edit:

This is now linked in the help docs.

• First line : array created.
• Third line loop started from j = 1 to j = 28123
• Fourth line you give the variable x value (0) each time the loop is accessed.
• Fifth line you put the value of j in the index 0.
• Sixth line you do increment to the value x by 1.(but it will be reset to 0 at line 4)

using include 'page1.php' in second page is one option but it can generate warnings and errors of undefined variables.
Three methods by which you can use variables of one php file in another php file:

• use session to pass variable from one page to another
  method:
  first you have to start the session in both the files using php command
  

  sesssion_start();
  then in first file consider you have one variable
  $x='var1';
  

  now assign value of $x to a session variable using this:
  $_SESSION['var']=$x;
  now getting value in any another php file:
  $y=$_SESSION['var'];//$y is any declared variable

• using get method and getting variables on clicking a link
  method
  

  <a href="page2.php?variable1=value1&variable2=value2">clickme</a>
  getting values in page2.php file by $_GET function:
  $x=$_GET['variable1'];//value1 be stored in $x
$y=$_GET['variable2'];//vale2 be stored in $y

• if you want to pass variable value using button then u can use it by following method:
  

  $x='value1'
<input type="submit" name='btn1' value='.$x.'/>
  in second php
  $var=$_POST['btn1'];

Could you do something like this?

>>> import pandas as pd
>>> df = pd.DataFrame(columns=['col1', 'col2'])
>>> df = df.append(pd.Series(['a', 'b'], index=['col1','col2']), ignore_index=True)
>>> df = df.append(pd.Series(['d', 'e'], index=['col1','col2']), ignore_index=True) 
>>> df
  col1 col2
0    a    b
1    d    e

Does anyone have a more elegant solution?

That is usually all that you need to do...

Are you sure that after 20 minutes, the reason that the session is being lost is from being idle though...

There are many reasons as to why the session might be cleared. You can enable event logging for IIS and can then use the event viewer to see reasons why the session was cleared...you might find that it is for other reasons perhaps?

You can also read the documentation for event messages and the associated table of events.

Rather Cast It to an Object Array.

Object obj2 = from some source . . ;
Object[] objects=(Object[])obj2;

Another important detail, the expires= should use the following date time format: Wdy, DD-Mon-YYYY HH:MM:SS GMT (RFC6265 - Section 4.1.1).

Set-Cookie:
  name=value;
  domain=localhost;
  expires=Thu, 16-07-2019 21:25:05 GMT;
  path=/

The second approach is best.

If you want to normalize it further you could create a table for question types

The simple things to do are:

• Place the database and log on their own disk, not all on C as default
• Create the database as large as needed so you do not have pauses while the database grows

We have had log tables in SQL Server Table with 10's of millions rows.

You can also just add an ON CONFLICT REPLACE clause to your user_name unique constraint and then just INSERT away, leaving it to SQLite to figure out what to do in case of a conflict. See:https://sqlite.org/lang_conflict.html.

Also note the sentence regarding delete triggers: When the REPLACE conflict resolution strategy deletes rows in order to satisfy a constraint, delete triggers fire if and only if recursive triggers are enabled.

When working with Angular the recent update to Angular 8 introduced that a static property inside @ViewChild() is required as stated here and here. Then your code would require this small change:

@ViewChild('one') d1:ElementRef;

into

// query results available in ngOnInit
@ViewChild('one', {static: true}) foo: ElementRef;

OR

// query results available in ngAfterViewInit
@ViewChild('one', {static: false}) foo: ElementRef;

The PIL distribution is mispackaged for egg installation.

Install Pillow instead, the friendly PIL fork.

All the metadata about the columns in Oracle Database is accessible using one of the following views.

user_tab_cols; -- For all tables owned by the user

all_tab_cols ; -- For all tables accessible to the user

dba_tab_cols; -- For all tables in the Database.

So, if you are looking for a column like ADD_TMS in SCOTT.EMP Table and add the column only if it does not exist, the PL/SQL Code would be along these lines..

DECLARE
  v_column_exists number := 0;  
BEGIN
  Select count(*) into v_column_exists
    from user_tab_cols
    where upper(column_name) = 'ADD_TMS'
      and upper(table_name) = 'EMP';
      --and owner = 'SCOTT --*might be required if you are using all/dba views

  if (v_column_exists = 0) then
      execute immediate 'alter table emp add (ADD_TMS date)';
  end if;
end;
/

If you are planning to run this as a script (not part of a procedure), the easiest way would be to include the alter command in the script and see the errors at the end of the script, assuming you have no Begin-End for the script..

If you have file1.sql

alter table t1 add col1 date;
alter table t1 add col2 date;
alter table t1 add col3 date;

And col2 is present,when the script is run, the other two columns would be added to the table and the log would show the error saying "col2" already exists, so you should be ok.

I have been looking at this. On populating the drop down anchors, I have given them a class and data attributes, so when needing to do an action you can do:

<li><a class="dropDownListItem" data-name="Fred Smith" href="#">Fred</a></li>

and then in the jQuery doing something like:

$('.dropDownListItem').click(function(e) {
    var name = e.currentTarget;
    console.log(name.getAttribute("data-name"));
});

So if you have dynamically generated list items in your dropdown and need to use the data that isn't just the text value of the item, you can use the data attributes when creating the dropdown listitem and then just give each item with the class the event, rather than referring to the id's of each item and generating a click event.

TL;DR

git show <commit>

Show

To show what a commit did with stats:

git show <commit> --stat

Log

To show commit log with differences introduced for each commit in a range:

git log -p <commit1> <commit2>

What is <commit>?

Each commit has a unique id we reference here as <commit>. The unique id is an SHA-1 hash – a checksum of the content you’re storing plus a header. #TMI

If you don't know your <commit>:

1. git log to view the commit history

2. Find the commit you care about.

Use req.app, req.app.get('somekey')

The application variable created by calling express() is set on the request and response objects.

As many people told, I will first start with the check - whether there exists an "is-a" relationship. If it exists I usually check the following:

Whether the base class can be instantiated. That is, whether the base class can be non-abstract. If it can be non-abstract I usually prefer composition

E.g 1. Accountant is an Employee. But I will not use inheritance because a Employee object can be instantiated.

E.g 2. Book is a SellingItem. A SellingItem cannot be instantiated - it is abstract concept. Hence I will use inheritacne. The SellingItem is an abstract base class (or interface in C#)

What do you think about this approach?

Also, I support @anon answer in Why use inheritance at all?

The main reason for using inheritance is not as a form of composition - it is so you can get polymorphic behaviour. If you don't need polymorphism, you probably should not be using inheritance.

@MatthieuM. says in https://softwareengineering.stackexchange.com/questions/12439/code-smell-inheritance-abuse/12448#comment303759_12448

The issue with inheritance is that it can be used for two orthogonal purposes:

interface (for polymorphism)

implementation (for code reuse)

let allText = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum";
let textBefore = "five centuries,";
let textAfter = "electronic typesetting";
var regExp = new RegExp(`(?<=${textBefore}\\s)(.+?)(?=\\s+${textAfter})`, "g");
var results = regExp.exec(allText);
if (results && results.length > 1) {
    console.log(results[0]);
}

We had the same problem when making our API as well. We were looking for an HTTP status code equivalent to an InvalidArgumentException. After reading the source article below, we ended up using 422 Unprocessable Entity which states:

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415 (Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

source: https://www.bennadel.com/blog/2434-http-status-codes-for-invalid-data-400-vs-422.htm

request.input("name", sql.Decimal, 155.33)              // decimal(18, 0)
request.input("name", sql.Decimal(10), 155.33)          // decimal(10, 0)
request.input("name", sql.Decimal(10, 2), 155.33)       // decimal(10, 2)

A DATE column does not have a format. You cannot specify a format for it.

You can use DateStyle to control how PostgreSQL emits dates, but it's global and a bit limited.

Instead, you should use to_char to format the date when you query it, or format it in the client application. Like:

SELECT to_char("date", 'DD/MM/YYYY') FROM mytable;

e.g.

regress=> SELECT to_char(DATE '2014-04-01', 'DD/MM/YYYY');
  to_char   
------------
 01/04/2014

If you're not using gradle (creating a project from an APK, for instance), this can be done through the Android Studio UI (as of version 3.3.2):

• Right-click the project root directory, pick Open Module Settings
• Hit the + Add Content Root button (center right)
• Add your path and hit OK

In my experience (with native code), as long as your .so's are built with debug symbols and from the same absolute paths, breakpoints added in source files will be automatically recognized.

Windows does not really support dual mode applications.

To see console output you need to create a console application

CONFIG += console

However, if you double click on the program to start the GUI mode version then you will get a console window appearing, which is probably not what you want. To prevent the console window appearing you have to create a GUI mode application in which case you get no output in the console.

One idea may be to create a second small application which is a console application and provides the output. This can call the second one to do the work.

Or you could put all the functionality in a DLL then create two versions of the .exe file which have very simple main functions which call into the DLL. One is for the GUI and one is for the console.

Try Below Solution

function replaceLinkClickableLink(url = '') {
let pattern = new RegExp('^(https?:\\/\\/)?'+
        '((([a-z\\d]([a-z\\d-]*[a-z\\d])*)\\.?)+[a-z]{2,}|'+
        '((\\d{1,3}\\.){3}\\d{1,3}))'+
        '(\\:\\d+)?(\\/[-a-z\\d%_.~+]*)*'+
        '(\\?[;&a-z\\d%_.~+=-]*)?'+
        '(\\#[-a-z\\d_]*)?$','i');

let isUrl = pattern.test(url);
if (isUrl) {
    return `<a href="${url}" target="_blank">${url}</a>`;
}
return url;
}

Yes you can use simply

     $input_data = $_POST;

or extract() may be useful for you.

The right way to set an item selected when the combobox is populated by some class' constructor (as @milosz posted):

combobox.getModel().setSelectedItem(new ClassName(parameter1, parameter2));

In your case the code would be:

test.getModel().setSelectedItem(new ComboItem(3, "banana"));

Youtube uses iframe. You can simply set it to:

iframe {
   display: block;
   margin: 0 auto;
}

use this filter:

(dns.flags.response == 0) and (ip.src == 159.25.78.7)

what this query does is it only gives dns queries originated from your ip

The best way I have found to do this, if you want to fully customize the button is to create a button, or any View you want (in my case it was a LinearLayout) and set an OnClickListener to that view, and call the following in the onClick event:

com.facebook.login.widget.LoginButton btn = new LoginButton(this);
btn.performClick();

This generator yields bytes from a file, reading the file in chunks:

def bytes_from_file(filename, chunksize=8192):
    with open(filename, "rb") as f:
        while True:
            chunk = f.read(chunksize)
            if chunk:
                for b in chunk:
                    yield b
            else:
                break

# example:
for b in bytes_from_file('filename'):
    do_stuff_with(b)

See the Python documentation for information on iterators and generators.

I had this issue while running MySQL on Minikube (Ubuntu box) and I solved it with:

sudo ln -s /etc/apparmor.d/usr.sbin.mysqld /etc/apparmor.d/disable/
sudo apparmor_parser -R /etc/apparmor.d/usr.sbin.mysqld

In my case, the svn relocate command (as well as svn switch --relocate) failed for some reason (maybe the repo was not moved correctly, or something else). I faced this error:

$ svn relocate NEW_SERVER
svn: E195009: The repository at 'NEW_SERVER' has uuid 'e7500204-160a-403c-b4b6-6bc4f25883ea', but the WC has '3a8c444c-5998-40fb-8cb3-409b74712e46'

I did not want to redownload the whole repository, so I found a workaround. It worked in my case, but generally I can imagine a lot of things can get broken (so either backup your working copy, or be ready to re-checkout the whole repo if something goes wrong).

The repo address and its UUID are saved in the .svn/wc.db SQLite database file in your working copy. Just open the database (e.g. in SQLite Browser), browse table REPOSITORY, and change the root and uuid column values to the new ones. You can find the UUID of the new repo by issuing svn info NEW_SERVER.

Again, treat this as a last resort method.

A. Grab file data from the file field

The first thing to do is bind a function to the change event on your file field and a function for grabbing the file data:

// Variable to store your files
var files;

// Add events
$('input[type=file]').on('change', prepareUpload);

// Grab the files and set them to our variable
function prepareUpload(event)
{
  files = event.target.files;
}

This saves the file data to a file variable for later use.

B. Handle the file upload on submit

When the form is submitted you need to handle the file upload in its own AJAX request. Add the following binding and function:

$('form').on('submit', uploadFiles);

// Catch the form submit and upload the files
function uploadFiles(event)
{
  event.stopPropagation(); // Stop stuff happening
    event.preventDefault(); // Totally stop stuff happening

// START A LOADING SPINNER HERE

// Create a formdata object and add the files
var data = new FormData();
$.each(files, function(key, value)
{
    data.append(key, value);
});

$.ajax({
    url: 'submit.php?files',
    type: 'POST',
    data: data,
    cache: false,
    dataType: 'json',
    processData: false, // Don't process the files
    contentType: false, // Set content type to false as jQuery will tell the server its a query string request
    success: function(data, textStatus, jqXHR)
    {
        if(typeof data.error === 'undefined')
        {
            // Success so call function to process the form
            submitForm(event, data);
        }
        else
        {
            // Handle errors here
            console.log('ERRORS: ' + data.error);
        }
    },
    error: function(jqXHR, textStatus, errorThrown)
    {
        // Handle errors here
        console.log('ERRORS: ' + textStatus);
        // STOP LOADING SPINNER
    }
});
}

What this function does is create a new formData object and appends each file to it. It then passes that data as a request to the server. 2 attributes need to be set to false:

• processData - Because jQuery will convert the files arrays into strings and the server can't pick it up.
• contentType - Set this to false because jQuery defaults to application/x-www-form-urlencoded and doesn't send the files. Also setting it to multipart/form-data doesn't seem to work either.

C. Upload the files

Quick and dirty php script to upload the files and pass back some info:

<?php // You need to add server side validation and better error handling here

$data = array();

if(isset($_GET['files']))
{  
$error = false;
$files = array();

$uploaddir = './uploads/';
foreach($_FILES as $file)
{
    if(move_uploaded_file($file['tmp_name'], $uploaddir .basename($file['name'])))
    {
        $files[] = $uploaddir .$file['name'];
    }
    else
    {
        $error = true;
    }
}
$data = ($error) ? array('error' => 'There was an error uploading your files') : array('files' => $files);
}
else
{
    $data = array('success' => 'Form was submitted', 'formData' => $_POST);
}

echo json_encode($data);

?>

IMP: Don't use this, write your own.

D. Handle the form submit

The success method of the upload function passes the data sent back from the server to the submit function. You can then pass that to the server as part of your post:

function submitForm(event, data)
{
  // Create a jQuery object from the form
$form = $(event.target);

// Serialize the form data
var formData = $form.serialize();

// You should sterilise the file names
$.each(data.files, function(key, value)
{
    formData = formData + '&filenames[]=' + value;
});

$.ajax({
    url: 'submit.php',
    type: 'POST',
    data: formData,
    cache: false,
    dataType: 'json',
    success: function(data, textStatus, jqXHR)
    {
        if(typeof data.error === 'undefined')
        {
            // Success so call function to process the form
            console.log('SUCCESS: ' + data.success);
        }
        else
        {
            // Handle errors here
            console.log('ERRORS: ' + data.error);
        }
    },
    error: function(jqXHR, textStatus, errorThrown)
    {
        // Handle errors here
        console.log('ERRORS: ' + textStatus);
    },
    complete: function()
    {
        // STOP LOADING SPINNER
    }
});
}

Final note

This script is an example only, you'll need to handle both server and client side validation and some way to notify users that the file upload is happening. I made a project for it on Github if you want to see it working.

A simple way to create a unique ID in JavaScript is to use the Date object:

var uniqid = Date.now();

That gives you the total milliseconds elapsed since January 1st 1970, which is a unique value every time you call that.

The problem with that value now is that you cannot use it as an element's ID, since in HTML, IDs need to start with an alphabetical character. There is also the problem that two users doing an action at the exact same time might result in the same ID. We could lessen the probability of that, and fix our alphabetical character problem, by appending a random letter before the numerical part of the ID.

var randLetter = String.fromCharCode(65 + Math.floor(Math.random() * 26));
var uniqid = randLetter + Date.now();

This still has a chance, however slim, of colliding though. Your best bet for a unique id is to keep a running count, increment it every time, and do all that in a single place, ie, on the server.

The easiest way that I use is this command on terminal:

docker logs elk > /home/Desktop/output.log

structure is:

docker logs <Container Name> > path/filename.log

Try looking at the BigDecimal Class. It is the go to class for currency and support accurate rounding.

For anyone who, like me, reads this because they need to update a giant legacy project to 5.6: as the answers here point out, there is no quick fix: you really do need to find each occurrence of the problem manually, and fix it.

The most convenient way I found to find all problematic lines in a project (short of using a full-blown static code analyzer, which is very accurate but I don't know any that take you to the correct position in the editor right away) was using Visual Studio Code, which has a nice PHP linter built in, and its search feature which allows searching by Regex. (Of course, you can use any IDE/Code editor for this that does PHP linting and Regex searches.)

Using this regex:

^(?!.*function).*(\&\$)

it is possible to search project-wide for the occurrence of &$ only in lines that are not a function definition.

This still turns up a lot of false positives, but it does make the job easier.

VSCode's search results browser makes walking through and finding the offending lines super easy: you just click through each result, and look out for those that the linter underlines red. Those you need to fix.

The exact length of a word varies. What I don't understand is what's the point of having a byte? Why not say 8 bits?

Even though the length of a word varies, on all modern machines and even all older architectures that I'm familiar with, the word size is still a multiple of the byte size. So there is no particular downside to using "byte" over "8 bits" in relation to the variable word size.

Beyond that, here are some reasons to use byte (or octet¹) over "8 bits":

1. Larger units are just convenient to avoid very large or very small numbers: you might as well ask "why say 3 nanoseconds when you could say 0.000000003 seconds" or "why say 1 kilogram when you could say 1,000 grams", etc.
2. Beyond the convenience, the unit of a byte is somehow as fundamental as 1 bit since many operations typically work not at the byte level, but at the byte level: addressing memory, allocating dynamic storage, reading from a file or socket, etc.
3. Even if you were to adopt "8 bit" as a type of unit, so you could say "two 8-bits" instead of "two bytes", it would be often be very confusing to have your new unit start with a number. For example, if someone said "one-hundred 8-bits" it could easily be interpreted as 108 bits, rather than 100 bits.

¹ Although I'll consider a byte to be 8 bits for this answer, this isn't universally true: on older machines a byte may have a different size (such as 6 bits. Octet always means 8 bits, regardless of the machine (so this term is often used in defining network protocols). In modern usage, byte is overwhelmingly used as synonymous with 8 bits.

In your XML for the image view, where you have android:background="@drawable/thumbs_down change this to android:src="@drawable/thumbs_down"

Currently it is placing that image as the background to the view and not the actual image in it.

It looks much like a list of Django ORM model instances.

Why not sort them on query like this:

There are already many nice answers to this problem but I would like to share a wonderful site that I came across when I couldnt solve the 'TesseractNotFound Error: tesseract is not installed or it's not in your path” Please refer this site: https://www.thetopsites.net/article/50655738.shtml

I realised that I got this error because I installed pytesseract with pip but forget to install the binary. You are probably missing tesseract-ocr from your machine. Check the installation instructions here: https://github.com/tesseract-ocr/tesseract/wiki

On a Mac, you can just install using homebrew:

brew install tesseract

It should run fine after that!

Under Windows 10 OS environment, the following method works for me:

1. Go to this link and Download tesseract and install it. Windows version is available here: https://github.com/UB-Mannheim/tesseract/wiki

2. Find script file pytesseract.py from C:\Users\User\Anaconda3\Lib\site-packages\pytesseract and open it. Change the following code from tesseract_cmd = 'tesseract' to: tesseract_cmd = 'C:/Program Files (x86)/Tesseract-OCR/tesseract.exe' (This is the path where you install Tesseract-OCR so please check where you install it and accordingly update the path)

3. You may also need to add environment variable C:/Program Files (x86)/Tesseract-OCR/

Hope it works for you!

if it is just a format issue use ToShortDateString()

The module pxssh does exactly what you want:
For example, to run 'ls -l' and to print the output, you need to do something like that :

from pexpect import pxssh
s = pxssh.pxssh()
if not s.login ('localhost', 'myusername', 'mypassword'):
    print "SSH session failed on login."
    print str(s)
else:
    print "SSH session login successful"
    s.sendline ('ls -l')
    s.prompt()         # match the prompt
    print s.before     # print everything before the prompt.
    s.logout()

Consider John Doe a document rather than a collection

Give it a collection of things and thingsSharedWithOthers

Then you can map and query John Doe's shared things in that parallel thingsSharedWithOthers collection.

proprietary: "John Doe"(a document)

things(collection of John's things documents)

thingsSharedWithOthers(collection of John's things being shared with others):
[thingId]:
    {who: "[email protected]", when:timestamp}
    {who: "[email protected]", when:timestamp}

then set thingsSharedWithOthers

firebase.firestore()
.collection('thingsSharedWithOthers')
.set(
{ [thingId]:{ who: "[email protected]", when: new Date() } },
{ merge: true }
)

Under Window > Preferences, go to the Run/Debug > Console section, then you should see an option "Limit console output." You can uncheck this or change the number in the "Console buffer size (characters)" text box below.

A Runnable is basically a type of class (Runnable is an Interface) that can be put into a thread, describing what the thread is supposed to do.

The Runnable Interface requires of the class to implement the method run() like so:

public class MyRunnableTask implements Runnable {
     public void run() {
         // do stuff here
     }
}

And then use it like this:

Thread t = new Thread(new MyRunnableTask());
t.start();

If you did not have the Runnable interface, the Thread class, which is responsible to execute your stuff in the other thread, would not have the promise to find a run() method in your class, so you could get errors. That is why you need to implement the interface.

Advanced: Anonymous Type

Note that you do not need to define a class as usual, you can do all of that inline:

Thread t = new Thread(new Runnable() {
    public void run() {
        // stuff here
    }
});
t.start();

This is similar to the above, only you don't create another named class.

This bug is filed here. This is a bug of android devices having API level less than 12. You've to put correct versions of your layouts in drawable-v12 folder which will be used for API level 12 or higher. And an erroneous version(corners switched/reversed) of the same layout will be put in the default drawable folder which will be used by the devices having API level less than 12.

For example: I had to design a button with rounded corner at bottom-right.

In 'drawable' folder - button.xml: I had to make bottom-left corner rounded.

<shape>
    <corners android:bottomLeftRadius="15dp"/>
</shape>

In 'drawable-v12' folder - button.xml: Correct version of the layout was placed here to be used for API level 12 or higher.

<shape>
    <corners android:bottomLeftRadius="15dp"/>
</shape>

Following is my project structure:

ProjectFolder:
 - project:
     - __init__.py
     - item.py
 - tests:
     - test_item.py

I found it better to import in the setUp() method:

import unittest
import sys    

class ItemTest(unittest.TestCase):

    def setUp(self):
        sys.path.insert(0, "../project")
        from project import item
        # further setup using this import

    def test_item_props(self):
        # do my assertions

if __name__ == "__main__":
    unittest.main()

1. In your project folder, create a “.gdbinit” text file. It will contain your gdb debugger configuration
2. Edit “.gdbinit”, and add the line (without the quotes) : “set new-console on”

3. After building the project right click on the project Debug > “Debug Configurations”, as shown below

4. In the “debugger” tab, ensure the “GDB command file” now points to your “.gdbinit” file. Else, input the path to your “.gdbinit” configuration file :

5. Click “Apply” and “Debug”. A native DOS command line should be launched as shown below

Another base R option could be gl():

gl(5, 3)

Where the output is a factor:

 [1] 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5
Levels: 1 2 3 4 5

If integers are needed, you can convert it:

as.numeric(gl(5, 3))

 [1] 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5

For me following worked:

in directive declare it like this:

.directive('myDirective', function() {
    return {
        restrict: 'E',
        replace: true,
        scope: {
            myFunction: '=',
        },
        templateUrl: 'myDirective.html'
    };
})  

In directive template use it in following way:

<select ng-change="myFunction(selectedAmount)">

And then when you use the directive, pass the function like this:

<data-my-directive
    data-my-function="setSelectedAmount">
</data-my-directive>

You pass the function by its declaration and it is called from directive and parameters are populated.

String.equals("") is actually a bit slower than just an isEmpty() call. Strings store a count variable initialized in the constructor, since Strings are immutable.

isEmpty() compares the count variable to 0, while equals will check the type, string length, and then iterate over the string for comparison if the sizes match.

So to answer your question, isEmpty() will actually do a lot less! and that's a good thing.

SELECT TOP 1 products.id FROM products WHERE products.id = ?; will outperform all of your suggestions as it will terminate execution after it finds the first record.

• IDEA-170117 "objc: Class JavaLaunchHelper is implemented in both ..." warning in Run consoles

It's the old bug in Java on Mac that got triggered by the Java Agent being used by the IDE when starting the app. This message is harmless and is safe to ignore. Oracle developer's comment:

The message is benign, there is no negative impact from this problem since both copies of that class are identical (compiled from the exact same source). It is purely a cosmetic issue.

The problem is fixed in Java 9 and in Java 8 update 152.

If it annoys you or affects your apps in any way (it shouldn't), the workaround for IntelliJ IDEA is to disable idea_rt launcher agent by adding idea.no.launcher=true into idea.properties (Help | Edit Custom Properties...). The workaround will take effect on the next restart of the IDE.

I don't recommend disabling IntelliJ IDEA launcher agent, though. It's used for such features as graceful shutdown (Exit button), thread dumps, workarounds a problem with too long command line exceeding OS limits, etc. Losing these features just for the sake of hiding the harmless message is probably not worth it, but it's up to you.

You can wrap your <span> with a <a> and use this little JQuery plugin to color the underline. You can modify the color by passing a parameter to the plugin.

    (function ($) {
        $.fn.useful = function (params) {

            var aCSS = {
                'color' : '#d43',
                'text-decoration' : 'underline'
            };

            $.extend(aCSS, params);

            this.wrap('<a></a>');
            var element = this.closest('a');
            element.css(aCSS);
            return element;
        };
    })(jQuery);

Then you call by writing this :

    $("span.name").useful({color:'red'});

$(function () {_x000D_

        var spanCSS = {_x000D_

It returns an array of all current classes of the element.
