This is a classic problem in CSS. There's not really a solution for this.

This article from A List Apart is a good read on this problem. It uses a technique called "faux columns", based on having one vertically tiled background image on the element containing the columns that creates the illusion of equal-length columns. Since it is on the floated elements' wrapper, it is as long as the longest element.

The A List Apart editors have this note on the article:

A note from the editors: While excellent for its time, this article may not reflect modern best practices.

The technique requires completely static width designs that doesn't work well with the liquid layouts and responsive design techniques that are popular today for cross-device sites. For static width sites, however, it's a reliable option.

Using 'async': false to prevent asynchronous code is a bad practice,

Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. https://xhr.spec.whatwg.org/

On the surface setting async to false fixes a lot of issues because, as the other answers show, you get your data into a variable. However, while waiting for the post data to return (which in some cases could take a few seconds because of database calls, slow connections, etc.) the rest of your Javascript functionality (like triggered events, Javascript handled buttons, JQuery transitions (like accordion, or autocomplete (JQuery UI)) will not be able to occur while the response is pending (which is really bad if the response never comes back as your site is now essentially frozen).

Try this instead,

var return_first;
function callback(response) {
  return_first = response;
  //use return_first variable here
}

$.ajax({
  'type': "POST",
  'global': false,
  'dataType': 'html',
  'url': "ajax.php?first",
  'data': { 'request': "", 'target': arrange_url, 'method': method_target },
  'success': function(data){
       callback(data);
  },
});

For those who rooted the Android device with Magisk, you can install adb_root from https://github.com/evdenis/adb_root. Then adb root can run smoothly.

Not with CSS directly, you could set CSS properties via JavaScript based on the internal contents but in the end you would still need to be operating in the definitions of CSS.

The consequence of this is that you may need a rather insane-looking query, e. g.,

SELECT [dbo].[tblTimeSheetExportFiles].[lngRecordID]            AS lngRecordID
          ,[dbo].[tblTimeSheetExportFiles].[vcrSourceWorkbookName]  AS vcrSourceWorkbookName
          ,[dbo].[tblTimeSheetExportFiles].[vcrImportFileName]      AS vcrImportFileName
          ,[dbo].[tblTimeSheetExportFiles].[dtmLastWriteTime]       AS dtmLastWriteTime
          ,[dbo].[tblTimeSheetExportFiles].[lngNRecords]            AS lngNRecords
          ,[dbo].[tblTimeSheetExportFiles].[lngSizeOnDisk]          AS lngSizeOnDisk
          ,[dbo].[tblTimeSheetExportFiles].[lngLastIdentity]        AS lngLastIdentity
          ,[dbo].[tblTimeSheetExportFiles].[dtmImportCompletedTime] AS dtmImportCompletedTime
          ,MIN ( [tblTimeRecords].[dtmActivity_Date] )              AS dtmPeriodFirstWorkDate
          ,MAX ( [tblTimeRecords].[dtmActivity_Date] )              AS dtmPeriodLastWorkDate
          ,SUM ( [tblTimeRecords].[decMan_Hours_Actual] )           AS decHoursWorked
          ,SUM ( [tblTimeRecords].[decAdjusted_Hours] )             AS decHoursBilled
      FROM [dbo].[tblTimeSheetExportFiles]
      LEFT JOIN   [dbo].[tblTimeRecords]
              ON  [dbo].[tblTimeSheetExportFiles].[lngRecordID] = [dbo].[tblTimeRecords].[lngTimeSheetExportFile]
        GROUP BY  [dbo].[tblTimeSheetExportFiles].[lngRecordID]
                 ,[dbo].[tblTimeSheetExportFiles].[vcrSourceWorkbookName]
                 ,[dbo].[tblTimeSheetExportFiles].[vcrImportFileName]
                 ,[dbo].[tblTimeSheetExportFiles].[dtmLastWriteTime]
                 ,[dbo].[tblTimeSheetExportFiles].[lngNRecords]
                 ,[dbo].[tblTimeSheetExportFiles].[lngSizeOnDisk]
                 ,[dbo].[tblTimeSheetExportFiles].[lngLastIdentity]
                 ,[dbo].[tblTimeSheetExportFiles].[dtmImportCompletedTime]

Since the primary table is a summary table, its primary key handles the only grouping or ordering that is truly necessary. Hence, the GROUP BY clause exists solely to satisfy the query parser.

For python 2 i did this

print ( time.strftime("%H:%M:%S", time.localtime(time.time())) + "." + str(time.time()).split(".",1)[1])

it prints time "%H:%M:%S" , splits the time.time() to two substrings (before and after the .) xxxxxxx.xx and since .xx are my milliseconds i add the second substring to my "%H:%M:%S"

hope that makes sense :) Example output:

INTRODUCTION

This answer corrects the very broken but shockingly top voted answer of this thread (written by TheMarko):

#!/usr/bin/env bash

BASEDIR=$(dirname "$0")
echo "$BASEDIR"

WHY DOES USING dirname "$0" ON IT'S OWN NOT WORK?

dirname $0 will only work if user launches script in a very specific way. I was able to find several situations where this answer fails and crashes the script.

First of all, let's understand how this answer works. He's getting the script directory by doing

dirname "$0"

$0 represents the first part of the command calling the script (it's basically the inputted command without the arguments:

/some/path/./script argument1 argument2

$0="/some/path/./script"

dirname basically finds the last / in a string and truncates it there. So if you do:

  dirname /usr/bin/sha256sum

you'll get: /usr/bin

This example works well because /usr/bin/sha256sum is a properly formatted path but

  dirname "/some/path/./script"

wouldn't work well and would give you:

  BASENAME="/some/path/." #which would crash your script if you try to use it as a path

Say you're in the same dir as your script and you launch it with this command

./script   

$0 in this situation will be ./script and dirname $0 will give:

. #or BASEDIR=".", again this will crash your script

Using:

sh script

Without inputting the full path will also give a BASEDIR="."

Using relative directories:

 ../some/path/./script

Gives a dirname $0 of:

 ../some/path/.

If you're in the /some directory and you call the script in this manner (note the absence of / in the beginning, again a relative path):

 path/./script.sh

You'll get this value for dirname $0:

 path/. 

and ./path/./script (another form of the relative path) gives:

 ./path/.

The only two situations where basedir $0 will work is if the user use sh or touch to launch a script because both will result in $0:

 $0=/some/path/script

which will give you a path you can use with dirname.

THE SOLUTION

You'd have account for and detect every one of the above mentioned situations and apply a fix for it if it arises:

#!/bin/bash
#this script will only work in bash, make sure it's installed on your system.

#set to false to not see all the echos
debug=true

if [ "$debug" = true ]; then echo "\$0=$0";fi


#The line below detect script's parent directory. $0 is the part of the launch command that doesn't contain the arguments
BASEDIR=$(dirname "$0") #3 situations will cause dirname $0 to fail: #situation1: user launches script while in script dir ( $0=./script)
                                                                     #situation2: different dir but ./ is used to launch script (ex. $0=/path_to/./script)
                                                                     #situation3: different dir but relative path used to launch script
if [ "$debug" = true ]; then echo 'BASEDIR=$(dirname "$0") gives: '"$BASEDIR";fi                                 

if [ "$BASEDIR" = "." ]; then BASEDIR="$(pwd)";fi # fix for situation1

_B2=${BASEDIR:$((${#BASEDIR}-2))}; B_=${BASEDIR::1}; B_2=${BASEDIR::2}; B_3=${BASEDIR::3} # <- bash only
if [ "$_B2" = "/." ]; then BASEDIR=${BASEDIR::$((${#BASEDIR}-1))};fi #fix for situation2 # <- bash only
if [ "$B_" != "/" ]; then  #fix for situation3 #<- bash only
        if [ "$B_2" = "./" ]; then
                #covers ./relative_path/(./)script
                if [ "$(pwd)" != "/" ]; then BASEDIR="$(pwd)/${BASEDIR:2}"; else BASEDIR="/${BASEDIR:2}";fi
        else
                #covers relative_path/(./)script and ../relative_path/(./)script, using ../relative_path fails if current path is a symbolic link
                if [ "$(pwd)" != "/" ]; then BASEDIR="$(pwd)/$BASEDIR"; else BASEDIR="/$BASEDIR";fi
        fi
fi

if [ "$debug" = true ]; then echo "fixed BASEDIR=$BASEDIR";fi

I solved this problem with conda and pip.

Firstly, I run:

conda uninstall qt and conda uninstall matplotlib and conda uninstall PyQt5

After that, I opened the cmd and run this code that

pip uninstall qt , pip uninstall matplotlib , pip uninstall PyQt5

Lastly, You should install matplotlib in pip by this code that pip install matplotlib

It means your Java runtime version is 1.8, but your compiler version (javac) is 1.6. To simply solve it, just retreat the Java version from 1.8 to 1.6.

But if you don't want to change the Java runtime version, then do the following steps:

1. JAVA_HOME= "your jdk v1.8 folder path", to make sure jdk is also v1.8 and use java -version and javac -version again to ensure it
2. Make sure IntelliJ 's compiler mode is set to compliant with v1.6 But i have tried that. it didn't solve my problem.

you can also try

git show <filename>

For commits, git show will show the log message and textual diff (between your file and the commited version of the file).

You can check git show Documentation for more info.

Use List<T>.Insert(0, item) or a LinkedList<T>.AddFirst().

In my case, I was using Google's Roboto font. So I had to import it at the beginning of my page with its proper weights.

<link href = "https://fonts.googleapis.com/css?family=Roboto+Mono|Roboto+Slab|Roboto:300,400,500,700" rel = "stylesheet" />

If you want it as a string (for example, a 10-digit phone number) you can use this:

n = 10
''.join(["{}".format(randint(0, 9)) for num in range(0, n)])

Most simple way,

use json.dumps but if its datetime will require to parse datetime into json serializer.

here is mine,

import MySQLdb, re, json
from datetime import date, datetime

def json_serial(obj):
    """JSON serializer for objects not serializable by default json code"""

    if isinstance(obj, (datetime, date)):
        return obj.isoformat()
    raise TypeError ("Type %s not serializable" % type(obj))

conn = MySQLdb.connect(instance)
curr = conn.cursor()
curr.execute("SELECT * FROM `assets`")
data = curr.fetchall()
print json.dumps(data, default=json_serial)

it will return json dump

one more simple method without json dumps, here get header and use zip to map with each finally made it as json but this is not change datetime into json serializer...

data_json = []
header = [i[0] for i in curr.description]
data = curr.fetchall()
for i in data:
    data_json.append(dict(zip(header, i)))
print data_json

Your first idea used to be the way but I've also noticed issues doing this using Firefox, try a straight http:// to the file - href='http://server/directory/file.xlsx'

I added a NuGet package, only to realize a black-box portion of my application was referencing an older version of the library.

I removed the package and referenced the older version's static DLL file, but the web.config file was never updated from:

<dependentAssembly>
    <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" />
    <bindingRedirect oldVersion="0.0.0.0-4.5.0.0" newVersion="6.0.0.0" />
</dependentAssembly>

to what it should have reverted to when I uninstalled the package:

<dependentAssembly>
    <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" />
    <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.5.0.0" />
</dependentAssembly>

Actually the last one is not weird. Code is setting the timezone for working instead of working2.

SimpleDateFormat working2 = new SimpleDateFormat("hh:mm:ss"); working.setTimeZone(TimeZone.getTimeZone("Etc/UTC"));

kk goes from 1 to 24, HH from 0 to 23 and hh from 1 to 12 (AM/PM).

Fixing this error gives:

24:00:00
00:00:00
01:00:00

Because growthRates is a sequence (you're even iterating it!) and you multiply it by (1 + 0.01), which is obviously a float (1.01). I guess you mean for growthRate in growthRates: ... * growthrate?

I'd use a different data structure, since array seem to be not the best solution.

Instead of array, use an object as a hash-table, like so:

(posted also in jsbin)

var arr = ["x", "y", "z"];
var map = {};
for (var k=0; k < arr.length; ++k) {
  map[arr[k]] = true;
}

function is_in_map(key) {
  try {
    return map[key] === true;
  } catch (e) {
    return false;
  }
}


function print_check(key) {
  console.log(key + " exists? - " + (is_in_map(key) ? "yes" : "no"));
}

print_check("x");
print_check("a");

Console output:

x exists? - yes
a exists? - no

That's a straight-forward solution. If you're more into an object oriented approach, then search Google for "js hashtable".

You could remove the folder and update the parent directory before committing:

rm -r some_dir

svn update some_dir_parent

Links can be within a variety of attributes so you could pass a list of those attributes to select

for example, with src and href attribute (here I am using the starts with ^ operator to specify that either of these attributes values starts with http. You can tailor this as required

from bs4 import BeautifulSoup as bs
import requests
r = requests.get('https://stackoverflow.com/')
soup = bs(r.content, 'lxml')
links = [item['href'] if item.get('href') is not None else item['src'] for item in soup.select('[href^="http"], [src^="http"]') ]
print(links)

Attribute = value selectors

[attr^=value]

Represents elements with an attribute name of attr whose value is prefixed (preceded) by value.

Your app is crashing at:

welcomePlayer.setText("Welcome Back, " + String.valueOf(mPlayer.getName(this)) + " !");

because mPlayer=null.

You forgot to initialize Player mPlayer in your PlayGame Activity.

mPlayer = new Player(context,"");

On Windows environment, you can execute py file on Python3 shell command line with the following syntax:

exec(open('absolute path to file_name').read())

Below explains how to execute a simple helloworld.py file from python shell command line

File Location: C:/Users/testuser/testfolder/helloworld.py

File Content: print("hello world")

We can execute this file on Python3.7 Shell as below:

>>> import os
>>> abs_path = 'C://Users/testuser/testfolder'
>>> os.chdir(abs_path)
>>> os.getcwd()
'C:\\Users\\testuser\\testfolder'

>>> exec(open("helloworld.py").read())
hello world

>>> exec(open("C:\\Users\\testuser\\testfolder\\helloworld.py").read())
hello world

>>> os.path.abspath("helloworld.py")
'C:\\Users\\testuser\\testfolder\\helloworld.py'
>>> import helloworld
hello world

You may use in input.

For example;

<input type=text name="test" autocomplete="off" />

The fileinput module of the Python standard library will rewrite a file inplace if you use the inplace=1 parameter:

import sys
import fileinput

# replace all occurrences of 'sit' with 'SIT' and insert a line after the 5th
for i, line in enumerate(fileinput.input('lorem_ipsum.txt', inplace=1)):
    sys.stdout.write(line.replace('sit', 'SIT'))  # replace 'sit' and write
    if i == 4: sys.stdout.write('\n')  # write a blank line after the 5th line

Tried with sudo and it worked !!

sudo npm install --global gulp-cli

You have to user ../../projectName/Filename.jsp in your action attr. or href

../ = contains current folder simple(demo.project.filename.jsp)

Servlet can only be called with 1 slash forward to your project name..

I would at first split the original string into an array of String with a token " (" and the String at position 0 of the output array is what you would like to have.

String[] output = originalString.split(" (");

String result = output[0];

Just type this command in Android Studio Terminal (Or your Linux/Mac Terminal)

chmod +x gradlew

and try to :

 ./gradlew assembleDebug

Your code is perfectly fine, you are just not looking at the right location to find your file. Since you haven't provided absolute path, your file will be created relative to the current working folder (more precisely in the current working folder in your case).

Your current working folder is set by Qt Creator. Go to Projects >> Your selected build >> Press the 'Run' button (next to 'Build) and you will see what it is on this page which of course you can change as well.

I had the same problem as the OP except I remembered to declare the ReadOnlyVariables.

After some playing around, I discovered it was the name of my variable that was the issue. "File_Path" in SSIS somehow got converted to "FilePath". C# does not play nicely with underscores in variable names.

So to access the variable, I type

string fp = Variables.FilePath;

In the PreExecute() method of the Script Component.

For me, I'm using Windows 10, @andrew-marshall's instructions worked (Thanks!) except that git.exe was within a cmd directory within PortableGit..., not bin, so I had to put \cmd on the end of the path I added to PATH. Thought I would post this here in case anyone else hits the same issue. You can tell it works once git in a new Command Prompt window returns command usage info and not an error.

Classic mode (the only mode in IIS6 and below) is a mode where IIS only works with ISAPI extensions and ISAPI filters directly. In fact, in this mode, ASP.NET is just an ISAPI extension (aspnet_isapi.dll) and an ISAPI filter (aspnet_filter.dll). IIS just treats ASP.NET as an external plugin implemented in ISAPI and works with it like a black box (and only when it's needs to give out the request to ASP.NET). In this mode, ASP.NET is not much different from PHP or other technologies for IIS.

Integrated mode, on the other hand, is a new mode in IIS7 where IIS pipeline is tightly integrated (i.e. is just the same) as ASP.NET request pipeline. ASP.NET can see every request it wants to and manipulate things along the way. ASP.NET is no longer treated as an external plugin. It's completely blended and integrated in IIS. In this mode, ASP.NET HttpModules basically have nearly as much power as an ISAPI filter would have had and ASP.NET HttpHandlers can have nearly equivalent capability as an ISAPI extension could have. In this mode, ASP.NET is basically a part of IIS.

I've perused almost all answers there, alas, as an undergraduate student taking OS course currently I can't comprehend thoroughly the two concepts. I mean most of guys read from some OS books the differences i.e. threads are able to access to global variables in the transaction unit since they make use of their process' address space. Yet, the newly question arises why there are processes, cognizantly we know already threads are more lightweight vis-à-vis processes. Let's glance at the following example by making use of the image excerpted from one of the prior answers,

We have 3 threads working at once on a word document e.g. Libre Office. The first does spellchecking by underlining if the word is misspelt. The second takes and prints letters from keyboard. And the last does save document in every short times not to lose the document worked at if something goes wrong. In this case, the 3 threads cannot be 3 processes since they share a common memory which is the address space of their process and thus all have access to the document being edited. So, the road is the word document along with two bulldozers which are the threads though one of them is lack in the image.

This technet link has some good info for copying large files. I used an exchange server utility mentioned in the article which shows progress and uses non buffered copy functions internally for faster transfer.

In another scenario, I used robocopy. Robocopy GUI makes it easier to get your command line options right.

I'm not aware of any way to do it using the standard library. But I do know and use this class that deals with html entities.

"HTMLEntities is an Open Source Java class that contains a collection of static methods (htmlentities, unhtmlentities, ...) to convert special and extended characters into HTML entitities and vice versa."

http://www.tecnick.com/public/code/cp_dpage.php?aiocp_dp=htmlentities

The terms resource and endpoint are often used synonymously. But in fact they do not mean the same thing.

The term endpoint is focused on the URL that is used to make a request.
The term resource is focused on the data set that is returned by a request.

Now, the same resource can often be accessed by multiple different endpoints.
Also the same endpoint can return different resources, depending on a query string.

Let us see some examples:

Different endpoints accessing the same resource

Have a look at the following examples of different endpoints:

/api/companies/5/employees/3
/api/v2/companies/5/employees/3
/api/employees/3

They obviously could all access the very same resource in a given API.

Also an existing API could be changed completely. This could lead to new endpoints that would access the same old resources using totally new and different URLs:

/api/employees/3
/new_api/staff/3

One endpoint accessing different resources

If your endpoint returns a collection, you could implement searching/filtering/sorting using query strings. As a result the following URLs all use the same endpoint (/api/companies), but they can return different resources (or resource collections, which by definition are resources in themselves):

/api/companies
/api/companies?sort=name_asc
/api/companies?location=germany
/api/companies?search=siemens

Just use pandas

list(pd.DataFrame(listofstuff).melt().values)

this only works for a list of lists

if you have a list of list of lists you might want to try something along the lines of

lists(pd.DataFrame(listofstuff).melt().apply(pd.Series).melt().values)

what is polymorphism?

From java tutorial

The dictionary definition of polymorphism refers to a principle in biology in which an organism or species can have many different forms or stages. This principle can also be applied to object-oriented programming and languages like the Java language. Subclasses of a class can define their own unique behaviors and yet share some of the same functionality of the parent class.

By considering the examples and definition, overriding should be accepted answer.

Regarding your second query:

IF you had a abstract base class that defined a method with no implementation, and you defined that method in the sub class, is that still overridding?

It should be called overriding.

Have a look at this example to understand different types of overriding.

1. Base class provides no implementation and sub-class has to override complete method - (abstract)
2. Base class provides default implementation and sub-class can change the behaviour
3. Sub-class adds extension to base class implementation by calling super.methodName() as first statement
4. Base class defines structure of the algorithm (Template method) and sub-class will override a part of algorithm

After adding Actuators to the spring boot bassed application you have /trace endpoint available with latest requests informations. This endpoint is working based on TraceRepository and default implementation is InMemoryTraceRepository that saves last 100 calls. You can change this by implementing this interface by yourself and make it available as a Spring bean. For example to log all requests to log (and still use default implementation as a basic storage for serving info on /trace endpoint) I'm using this kind of implementation:

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.actuate.trace.InMemoryTraceRepository;
import org.springframework.boot.actuate.trace.Trace;
import org.springframework.boot.actuate.trace.TraceRepository;
import org.springframework.stereotype.Component;

import java.util.List;
import java.util.Map;


@Component
public class LoggingTraceRepository implements TraceRepository {

  private static final Logger LOG = LoggerFactory.getLogger(LoggingTraceRepository.class);
  private final TraceRepository delegate = new InMemoryTraceRepository();

  @Override
  public List<Trace> findAll() {
    return delegate.findAll();
  }

  @Override
  public void add(Map<String, Object> traceInfo) {
    LOG.info(traceInfo.toString());
    this.delegate.add(traceInfo);
  }
}

This traceInfo map contains basic informations about request and response in this kind of form: {method=GET, path=/api/hello/John, headers={request={host=localhost:8080, user-agent=curl/7.51.0, accept=*/*}, response={X-Application-Context=application, Content-Type=text/plain;charset=UTF-8, Content-Length=10, Date=Wed, 29 Mar 2017 20:41:21 GMT, status=200}}}. There is NO response content here.

EDIT! Logging POST data

You can access POST data by overriding WebRequestTraceFilter, but don't think it is a good idea (e.g. all uploaded file content will go to logs) Here is sample code, but don't use it:

package info.fingo.nuntius.acuate.trace;

import org.apache.commons.io.IOUtils;
import org.springframework.boot.actuate.trace.TraceProperties;
import org.springframework.boot.actuate.trace.TraceRepository;
import org.springframework.boot.actuate.trace.WebRequestTraceFilter;
import org.springframework.stereotype.Component;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import java.io.IOException;
import java.nio.charset.Charset;
import java.util.LinkedHashMap;
import java.util.Map;

@Component
public class CustomWebTraceFilter extends WebRequestTraceFilter {

  public CustomWebTraceFilter(TraceRepository repository, TraceProperties properties) {
    super(repository, properties);
}

  @Override
  protected Map<String, Object> getTrace(HttpServletRequest request) {
    Map<String, Object> trace = super.getTrace(request);
    String multipartHeader = request.getHeader("content-type");
    if (multipartHeader != null && multipartHeader.startsWith("multipart/form-data")) {
        Map<String, Object> parts = new LinkedHashMap<>();
        try {
            request.getParts().forEach(
                    part -> {
                        try {
                            parts.put(part.getName(), IOUtils.toString(part.getInputStream(), Charset.forName("UTF-8")));
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                    }
            );
        } catch (IOException | ServletException e) {
            e.printStackTrace();
        }
        if (!parts.isEmpty()) {
            trace.put("multipart-content-map", parts);
        }
    }
    return trace;
  }
}

HttpWebRequest webRequest = WebRequest.Create(uirTradeStream) as HttpWebRequest;

webRequest.Proxy = WebRequest.DefaultWebProxy;

webRequest.Credentials = new NetworkCredential("user", "password");

webRequest.Proxy.Credentials = new NetworkCredential("user", "password");

It is successful.

Interesting/funny way to do this using parameter expansion (requires bash 4.4 or newer):

${parameter@operator} - P operator

The expansion is a string that is the result of expanding the value of parameter as if it were a prompt string.

$ show_time() { local format='\D{%Y%m%d%H%M%S}'; echo "${format@P}"; }
$ show_time

Lists represent a sequential ordering of elements. Maps are used to represent a collection of key / value pairs.

While you could use a map as a list, there are some definite downsides of doing so.

Maintaining order: - A list by definition is ordered. You add items and then you are able to iterate back through the list in the order that you inserted the items. When you add items to a HashMap, you are not guaranteed to retrieve the items in the same order you put them in. There are subclasses of HashMap like LinkedHashMap that will maintain the order, but in general order is not guaranteed with a Map.

Key/Value semantics: - The purpose of a map is to store items based on a key that can be used to retrieve the item at a later point. Similar functionality can only be achieved with a list in the limited case where the key happens to be the position in the list.

Code readability Consider the following examples.

    // Adding to a List
    list.add(myObject);         // adds to the end of the list
    map.put(myKey, myObject);   // sure, you can do this, but what is myKey?
    map.put("1", myObject);     // you could use the position as a key but why?

    // Iterating through the items
    for (Object o : myList)           // nice and easy
    for (Object o : myMap.values())   // more code and the order is not guaranteed

Collection functionality Some great utility functions are available for lists via the Collections class. For example ...

    // Randomize the list
    Collections.shuffle(myList);

    // Sort the list
    Collections.sort(myList, myComparator);  

Hope this helps,

If you're displaying a user-readable file name, you do not want to use lastPathComponent. Instead, pass the full path to NSFileManager's displayNameAtPath: method. This basically does does the same thing, only it correctly localizes the file name and removes the extension based on the user's preferences.

Docker for Mac is deprecated. And you don't need Homebrew to run Docker on Mac. Instead you'll likely want to install Docker Desktop or, if already installed, make sure it's up-to-date and running, then attempt to connect to the socket again.

Using !important will override element.style via CSS like Change

color: #7D7D7D;

to

color: #7D7D7D !important;

That should do it.

Unfortunately we need to run docker-compose logs separately from docker-compose run. In order to get this to work reliably we need to suppress the docker-compose run exit status then redirect the log and exit with the right status.

#!/bin/bash
set -euo pipefail
docker-compose run app | tee app.log || failed=yes
docker-compose logs --no-color > docker-compose.log
[[ -z "${failed:-}" ]] || exit 1

This seems to be answered - #include <fstream>.

The message means :-

incomplete type - the class has not been defined with a full class. The compiler has seen statements such as class ifstream; which allow it to understand that a class exists, but does not know how much memory the class takes up.

The forward declaration allows the compiler to make more sense of :-

void BindInput( ifstream & inputChannel ); 

It understands the class exists, and can send pointers and references through code without being able to create the class, see any data within the class, or call any methods of the class.

The has initializer seems a bit extraneous, but is saying that the incomplete object is being created.

Sum the object key value by parse Integer. Converting string format to integer and summing the values

var obj = {
  pay: 22
};
obj.pay;
console.log(obj.pay);
var x = parseInt(obj.pay);
console.log(x + 20);

It is actually a 3 step process to connect to a PostgreSQL server remotely through pgAdmin3.

Note: I use Ubuntu 11.04 and PostgreSQL 8.4.

1. You have to make PostgreSQL listening for remote incoming TCP connections because the default settings allow to listen only for connections on the loopback interface. To be able to reach the server remotely you have to add the following line into the file /etc/postgresql/8.4/main/postgresql.conf:

   listen_addresses = '*'

2. PostgreSQL by default refuses all connections it receives from any remote address, you have to relax these rules by adding this line to /etc/postgresql/8.4/main/pg_hba.conf:

   host all all 0.0.0.0/0 md5

   This is an access control rule that let anybody login in from any address if he can provide a valid password (the md5 keyword). You can use needed network/mask instead of 0.0.0.0/0 .

3. When you have applied these modifications to your configuration files you need to restart PostgreSQL server. Now it is possible to login to your server remotely, using the username and password.

Sounds like the instance was launched in VPC and while doing so, the check-box for Automatically assign a public IP address to your instances was not checked. Hence the instance does not have a public IP

You can assign an Elastic IP to this instance and then log in using that IP.

This should do:

xhr = new XMLHttpRequest();
xhr.open("GET", "/soap/ajax/11.0/connection.js", false);
xhr.send();
eval(xhr.responseText);

Analyze @staticmethod literally providing different insights.

A normal method of a class is an implicit dynamic method which takes the instance as first argument.
In contrast, a staticmethod does not take the instance as first argument, so is called 'static'.

A staticmethod is indeed such a normal function the same as those outside a class definition.
It is luckily grouped into the class just in order to stand closer where it is applied, or you might scroll around to find it.

Serge is right - my workaround:

function mySleep (sec)
{
  SpreadsheetApp.flush();
  Utilities.sleep(sec*1000);
  SpreadsheetApp.flush();
}

You can do the same in Razor or in the Controller, like so..

@{
    //do this on the top most of your View, immediately after `using` statement
    Response.ContentType = "application/pdf";
    Response.AddHeader("Content-Disposition", "attachment; filename=receipt.pdf");
}

Or in the Controller..

public ActionResult Receipt() {
    Response.ContentType = "application/pdf";
    Response.AddHeader("Content-Disposition", "attachment; filename=receipt.pdf");

    return View();
}

I tried this in Chrome and IE9, both is downloading the pdf file.

I probably should add I am using RazorPDF to generate my PDFs. Here is a blog about it: http://nyveldt.com/blog/post/Introducing-RazorPDF

Find the custom validator for min number validation. The selector name of our directive is customMin.

custom-min-validator.directive.ts

import { Directive, Input } from '@angular/core';
import { NG_VALIDATORS, Validator, FormControl } from '@angular/forms';

@Directive({
  selector: '[customMin][formControlName],[customMin][formControl],[customMin][ngModel]',
  providers: [{provide: NG_VALIDATORS, useExisting: CustomMinDirective, multi: true}]
})
export class CustomMinDirective implements Validator {
  @Input()
  customMin: number;

  validate(c: FormControl): {[key: string]: any} {
      let v = c.value;
      return ( v < this.customMin)? {"customMin": true} : null;
  }
} 

Find the custom validator for max number validation. The selector name of our directive is customMax.

custom-max-validator.directive.ts

import { Directive, Input } from '@angular/core';
import { NG_VALIDATORS, Validator, FormControl } from '@angular/forms';

@Directive({
  selector: '[customMax][formControlName],[customMax][formControl],[customMax][ngModel]',
  providers: [{provide: NG_VALIDATORS, useExisting: CustomMaxDirective, multi: true}]
})
export class CustomMaxDirective implements Validator {
  @Input()
  customMax: number;

  validate(c: FormControl): {[key: string]: any} {
      let v = c.value;
      return ( v > this.customMax)? {"customMax": true} : null;
  }
} 

We can use customMax with formControlName, formControl and ngModel attributes.

Using Custom Min and Max Validator in Template-driven Form

We will use our custom min and max validator in template-driven form. For min number validation we have customMin attribute and for max number validation we have customMax attribute. Now find the code snippet for validation.

<input name="num1" [ngModel]="user.num1" customMin="15" #numberOne="ngModel">
<input name="num2" [ngModel]="user.num2" customMax="50"  #numberTwo="ngModel"> 

We can show validation error messages as following.

<div *ngIf="numberOne.errors?.customMin"> 
     Minimum required number is 15.
</div>  

<div *ngIf="numberTwo.errors?.customMax"> 
     Maximum number can be 50.
</div> 

To assign min and max number we can also use property biding. Suppose we have following component properties.

minNum = 15;
maxNum = 50; 

Now use property binding for customMin and customMax as following.

<input name="num1" [ngModel]="user.num1" [customMin]="minNum" #numberOne="ngModel">
<input name="num2" [ngModel]="user.num2" [customMax]="maxNum"  #numberTwo="ngModel"> 

have you tried size() ? Something like :

jar.size();

Hope it helps.

I found that:

git log --reverse

shows commits from start.

This will return default size of text on button in pixels.

Kotlin

val size = Button(this).textSize

Java

float size = new Button(this).getTextSize();

turns out it has to do with ng-Route and the order of loading script wrote a directive and put the API script on top of everything works.

Just use Url.Action instead of Html.ActionLink:

<li id="home_nav"><a href="<%= Url.Action("ActionName") %>"><span>Span text</span></a></li>

locals() returns a dictionary with local names:

def func(a,b,c):
    print(locals().keys())

prints the list of parameters. If you use other local variables those will be included in this list. But you could make a copy at the beginning of your function.

If you have longer query and you like to use psql then put your query to a file and use the following command:

psql -d my_db_name -t -A -F";" -f input-file.sql -o output-file.csv

use this attribute in style

font-size: 11px !important;//your font size

by !important it override your css

An alternative is Joda-Time.

Use DateTime

DateTime date = new DateTime(new Date());
date.isBeforeNow();
or
date.isAfterNow();

A little bit late and perhaps still good for complex if-conditions, because I would like to add a "done" parameter to keep a if-then-else structure:

set done=0
if %F%==1 if %C%==0 (set done=1 & echo found F=1 and C=0: %F% + %C%)
if %F%==2 if %C%==0 (set done=1 & echo found F=2 and C=0: %F% + %C%)
if %F%==3 if %C%==0 (set done=1 & echo found F=3 and C=0: %F% + %C%)
if %done%==0 (echo do something)

Use the -printcert command like this:

keytool -printcert -file certificate.pem

I linux this works too:

import sys
sys.path.extend(["/path/to/dotpy/file/"])

you could access the data using $('#prod')[0].dataset

This part has problems:

Card* cardArray;
void Deck() {
    cardArray = new Card[NUM_TOTAL_CARDS];
    int cardCount = 0;
    for (int i = 0; i > NUM_SUITS; i++) {  //Error
        for (int j = 0; j > NUM_RANKS; j++) { //Error
            cardArray[cardCount] = Card(Card::Rank(i), Card::Suit(j) );
            cardCount++;
         }
    }
 }

1. cardArray is a dynamic array, but not a member of Card class. It is strange if you would like to initialize a dynamic array which is not member of the class
2. void Deck() is not constructor of class Deck since you missed the scope resolution operator. You may be confused with defining the constructor and the function with name Deck and return type void.
3. in your loops, you should use < not > otherwise, loop will never be executed.

Combining much of above here is my real practical example, selecting records based on both meterid & timestamp. I have needed this command for years. Executes really quickly.

mysqldump -uuser -ppassword main_dbo trHourly --where="MeterID =5406 AND TIMESTAMP<'2014-10-13 05:00:00'" --no-create-info --skip-extended-insert | grep  '^INSERT' > 5406.sql

class CountryListView(ListView):
     model = Country

    def render_to_response(self, context, **response_kwargs):

         return HttpResponse(json.dumps(list(self.get_queryset().values_list('code', flat=True))),mimetype="application/json") 

fixed the problem

also mimetype is important.

You can prevent the crash from happening by safely unwrapping cell.labelTitle with an if let statement.

if let label = cell.labelTitle{
    label.text = "This is a title"
}

You will still have to do some debugging to see why you are getting a nil value there though.

Don't use stream.stop(), it's deprecated

Under linux, I think ping -b 192.168.1.255 will work (192.168.1.255 is the broadcast address for 192.168.1.*) however IIRC that doesn't work under windows.

<strong> and <em> add extra semantic meaning to your document. It just so happens that they also give a bold and italic style to your text.

You could of course override their styling with CSS.

<b> and <i> on the other hand only apply font styling and should no longer be used. (Because you're supposed to format with CSS, and if the text was actually important then you would probably make it "strong" or "emphasised" anyway!)

Hope that makes sense.

The most "foolproof" way is to check for the availability of URL:

public boolean isURL(String url) {
  try {
     (new java.net.URL(url)).openStream().close();
     return true;
  } catch (Exception ex) { }
  return false;
}

The cleanest solution is to use Auto Layout. I lowered Content Compression Resistance Priority of my UIButton and set the image (not Background Image) via Interface Builder. After that I added a couple of constraints that define size of my button (quite complex in my case) and it worked like a charm.

This might work well to remove special characters.

$modifiedString = preg_replace("/[^a-zA-Z0-9_.-\s]/", "", $content); 

I was scratching my head about this for a while too, and since Dave's explanation is a little hard to understand I'll post my (apparently working) code:

private class TabListener<T extends Fragment> implements ActionBar.TabListener {
    private Fragment mFragment;
    private Activity mActivity;
    private final String mTag;
    private final Class<T> mClass;

    public TabListener(Activity activity, String tag, Class<T> clz) {
        mActivity = activity;
        mTag = tag;
        mClass = clz;
        mFragment=mActivity.getFragmentManager().findFragmentByTag(mTag);
    }

    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        if (mFragment == null) {
            mFragment = Fragment.instantiate(mActivity, mClass.getName());
            ft.replace(android.R.id.content, mFragment, mTag);
        } else {
            if (mFragment.isDetached()) {
                ft.attach(mFragment);
            }
        }
    }

    public void onTabUnselected(Tab tab, FragmentTransaction ft) {
        if (mFragment != null) {
            ft.detach(mFragment);
        }
    }

    public void onTabReselected(Tab tab, FragmentTransaction ft) {
    }
}

As you can see it's pretty much like the Android sample, apart from not detaching in the constructor, and using replace instead of add.

After much headscratching and trial-and-error I found that finding the fragment in the constructor seems to make the double onCreateView problem magically go away (I assume it just ends up being null for onTabSelected when called through the ActionBar.setSelectedNavigationItem() path when saving/restoring state).

Someone asked about adding attributes (specifically, 'rows' and 'cols'). If you're using Razor, you could just do this:

@Html.TextAreaFor(model => model.Text, new { cols = 35, @rows = 3 })

That works for me. The '@' is used to escape keywords so they are treated as variables/properties.

I've experienced problems with large sqlite files when using the vacuum command.

I haven't tried the auto_vacuum feature yet. If you expect to be updating and deleting data often then this is worth looking at.

Its BECAUSE there is no font family with name @"System" hence size:36 will also not work ...

Check the fonts available in xcode in attribute inspector and try

var str = "ff ff f f a de def";
str = str.replace(/f/g,'');
alert(str);

In simpler terms, Imagine if you want mock below line:

StaticClass.method();

then you write below lines of code to mock:

PowerMockito.mockStatic(StaticClass.class);
PowerMockito.doNothing().when(StaticClass.class);
StaticClass.method();

Check your file: settings.gradle for presence lines with included subprojects (for example: include chapter1-bookstore )

Source for the Data warehouse can be cluster of Databases, because databases are used for Online Transaction process like keeping the current records..but in Data warehouse it stores historical data which are for Online analytical process.

Quick fix - make sure all variables which do not get initialized when they are created (eg var num : Int? vs var num = 5) have either a ? or !.

Long answer (reccomended) - read the doc as per mprivat suggests...

It can be done with only CSS. But they asked with jQuery or JavaScript

Here, use CSS Flex box property to align the div center.

body.center{
  display:flex;
  align-items:center; // Vertical alignment
  justify-content:center; // Horizontal alignment
}

align-items:center; - used to align vertically.

justify-content:center; - used to align horizontally.

document.querySelector("body").classList.add("center");

body {
  margin : 0;
  height:100vh;
  width:100%;
  background: #ccc;
}
#main{
  background:#00cc00;
  width:100px;
  height:100px;
}
body.center{
  display:flex;
  align-items:center;
  justify-content:center;
}

<body>
  <div id="main"></div>
</body>

From Files and Filegroups Architecture

Secondary data files

Secondary data files make up all the data files, other than the primary data file. Some databases may not have any secondary data files, while others have several secondary data files. The recommended file name extension for secondary data files is .ndf.

Also from file extension NDF - Microsoft SQL Server secondary data file

See Understanding Files and Filegroups

Secondary data files are optional, are user-defined, and store user data. Secondary files can be used to spread data across multiple disks by putting each file on a different disk drive. Additionally, if a database exceeds the maximum size for a single Windows file, you can use secondary data files so the database can continue to grow.

The recommended file name extension for secondary data files is .ndf.

/

For example, three files, Data1.ndf, Data2.ndf, and Data3.ndf, can be created on three disk drives, respectively, and assigned to the filegroup fgroup1. A table can then be created specifically on the filegroup fgroup1. Queries for data from the table will be spread across the three disks; this will improve performance. The same performance improvement can be accomplished by using a single file created on a RAID (redundant array of independent disks) stripe set. However, files and filegroups let you easily add new files to new disks.

See it in Activity Lifecycle (at Android Developers).

onCreate():

Called when the activity is first created. This is where you should do all of your normal static set up: create views, bind data to lists, etc. This method also provides you with a Bundle containing the activity's previously frozen state, if there was one. Always followed by onStart().

onRestart():

Called after your activity has been stopped, prior to it being started again. Always followed by onStart()

onStart():

Called when the activity is becoming visible to the user. Followed by onResume() if the activity comes to the foreground.

onResume():

Called when the activity will start interacting with the user. At this point your activity is at the top of the activity stack, with user input going to it. Always followed by onPause().

onPause ():

Called as part of the activity lifecycle when an activity is going into the background, but has not (yet) been killed. The counterpart to onResume(). When activity B is launched in front of activity A, this callback will be invoked on A. B will not be created until A's onPause() returns, so be sure to not do anything lengthy here.

onStop():

Called when you are no longer visible to the user. You will next receive either onRestart(), onDestroy(), or nothing, depending on later user activity. Note that this method may never be called, in low memory situations where the system does not have enough memory to keep your activity's process running after its onPause() method is called.

onDestroy():

The final call you receive before your activity is destroyed. This can happen either because the activity is finishing (someone called finish() on it, or because the system is temporarily destroying this instance of the activity to save space. You can distinguish between> these two scenarios with the isFinishing() method.

When the Activity first time loads the events are called as below:

onCreate()
onStart()
onResume()

When you click on Phone button the Activity goes to the background and the below events are called:

onPause()
onStop()

Exit the phone dialer and the below events will be called:

onRestart()
onStart()
onResume()

When you click the back button OR try to finish() the activity the events are called as below:

onPause()
onStop()
onDestroy()

Activity States

The Android OS uses a priority queue to assist in managing activities running on the device. Based on the state a particular Android activity is in, it will be assigned a certain priority within the OS. This priority system helps Android identify activities that are no longer in use, allowing the OS to reclaim memory and resources. The following diagram illustrates the states an activity can go through, during its lifetime:

These states can be broken into three main groups as follows:

Active or Running - Activities are considered active or running if they are in the foreground, also known as the top of the activity stack. This is considered the highest priority activity in the Android Activity stack, and as such will only be killed by the OS in extreme situations, such as if the activity tries to use more memory than is available on the device as this could cause the UI to become unresponsive.

Paused - When the device goes to sleep, or an activity is still visible but partially hidden by a new, non-full-sized or transparent activity, the activity is considered paused. Paused activities are still alive, that is, they maintain all state and member information, and remain attached to the window manager. This is considered to be the second highest priority activity in the Android Activity stack and, as such, will only be killed by the OS if killing this activity will satisfy the resource requirements needed to keep the Active/Running Activity stable and responsive.

Stopped - Activities that are completely obscured by another activity are considered stopped or in the background. Stopped activities still try to retain their state and member information for as long as possible, but stopped activities are considered to be the lowest priority of the three states and, as such, the OS will kill activities in this state first to satisfy the resource requirements of higher priority activities.

*Sample activity to understand the life cycle**

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class MainActivity extends Activity {
    String tag = "LifeCycleEvents";
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);
       Log.d(tag, "In the onCreate() event");
    }
    public void onStart()
    {
       super.onStart();
       Log.d(tag, "In the onStart() event");
    }
    public void onRestart()
    {
       super.onRestart();
       Log.d(tag, "In the onRestart() event");
    }
    public void onResume()
    {
       super.onResume();
       Log.d(tag, "In the onResume() event");
    }
    public void onPause()
    {
       super.onPause();
       Log.d(tag, "In the onPause() event");
    }
    public void onStop()
    {
       super.onStop();
       Log.d(tag, "In the onStop() event");
    }
    public void onDestroy()
    {
       super.onDestroy();
       Log.d(tag, "In the onDestroy() event");
    }
}

Having something like this:

let headers = new Headers();
headers.append('Content-Type', 'application/json');
headers.append('projectid', this.id);
let params = new URLSearchParams();
params.append("someParamKey", this.someParamValue)

this.http.get('http://localhost:63203/api/CallCenter/GetSupport', { headers: headers, search: params })

Of course, appending every param you need to params. It gives you a lot more flexibility than just using a URL string to pass params to the request.

EDIT(28.09.2017): As Al-Mothafar stated in a comment, search is deprecated as of Angular 4, so you should use params

EDIT(02.11.2017): If you are using the new HttpClient there are now HttpParams, which look and are used like this:

let params = new HttpParams().set("paramName",paramValue).set("paramName2", paramValue2); //Create new HttpParams

And then add the params to the request in, basically, the same way:

this.http.get(url, {headers: headers, params: params}); 
//No need to use .map(res => res.json()) anymore

More in the docs for HttpParams and HttpClient

I have a better solution for this problem,

• request is a member of abstract class ControllerBase
• GetSearchParams() is an extension method created in bellow helper class.

var searchparams = await Request.GetSearchParams();

I have created a static class with few extension methods

public static class HttpRequestExtension
{
  public static async Task<SearchParams> GetSearchParams(this HttpRequest request)
        {
            var parameters = await request.TupledParameters();

            try
            {
                for (var i = 0; i < parameters.Count; i++)
                {
                    if (parameters[i].Item1 == "_count" && parameters[i].Item2 == "0")
                    {
                        parameters[i] = new Tuple<string, string>("_summary", "count");
                    }
                }
                var searchCommand = SearchParams.FromUriParamList(parameters);
                return searchCommand;
            }
            catch (FormatException formatException)
            {
                throw new FhirException(formatException.Message, OperationOutcome.IssueType.Invalid, OperationOutcome.IssueSeverity.Fatal, HttpStatusCode.BadRequest);
            }
        }



public static async Task<List<Tuple<string, string>>> TupledParameters(this HttpRequest request)
{
        var list = new List<Tuple<string, string>>();


        var query = request.Query;
        foreach (var pair in query)
        {
            list.Add(new Tuple<string, string>(pair.Key, pair.Value));
        }

        if (!request.HasFormContentType)
        {
            return list;
        }
        var getContent = await request.ReadFormAsync();

        if (getContent == null)
        {
            return list;
        }
        foreach (var key in getContent.Keys)
        {
            if (!getContent.TryGetValue(key, out StringValues values))
            {
                continue;
            }
            foreach (var value in values)
            {
                list.Add(new Tuple<string, string>(key, value));
            }
        }
        return list;
    }
}

in this way you can easily access all your search parameters. I hope this will help many developers :)

All above solutions are correct. But, when we are talking about a normal PHP application, they have to included in every page, that it requires. A way to solve this, is through .htaccess at root folder. Just to hide the errors. [Put one of the followling lines in the file]

php_flag display_errors off

Or

php_value display_errors 0

Next, to set the error reporting

php_value error_reporting 30719

If you are wondering how the value 30719 came, E_ALL (32767), E_STRICT (2048) are actually constant that hold numeric value and (32767 - 2048 = 30719)

I've used jQuery MultiSelect for implementing multiselect drop down menu with checkbox. You can see the implementation guide from here - Multi-select Dropdown List with Checkbox

Implementation is very simple, need only using the following code.

$('#transactionType').multiselect({
    columns: 1,
    placeholder: 'Select Transaction Type'
});

I was facing a similar problem when I was trying to do a custom view for a ListView.

I solved it simply by doing this:

public View getView(int i, View view, ViewGroup viewGroup) {

    // Gets the inflater
    LayoutInflater inflater = LayoutInflater.from(this.contexto);

    // Inflates the layout
    ConstraintLayout cl2 = (ConstraintLayout) 
    inflater.inflate(R.layout.custom_list_view, viewGroup, false);

    //Insted of calling just findViewById, I call de cl2.findViewById method. cl2 is the layout I have just inflated. 
     TextView tv1 = (TextView)cl2.findViewById(cl2);

The problem here is that your timer starts a thread and when it runs the callback function, the callback function ( updatelistview) is accessing controls on UI thread so this can not be done becuase of this

There is no such syntax in SQL Server, though CREATE TABLE AS ... SELECT does exist in PDW. In SQL Server you can use this query to create an empty table:

SELECT * INTO schema.newtable FROM schema.oldtable WHERE 1 = 0;

(If you want to make a copy of the table including all of the data, then leave out the WHERE clause.)

Note that this creates the same column structure (including an IDENTITY column if one exists) but it does not copy any indexes, constraints, triggers, etc.

To Get TEXT attributes added from admin to front end on product listing page.

Thanks Anita Mourya

I have found there is two methods. Let say product attribute called "na_author" is added from backend as text field.

METHOD 1

on list.phtml

<?php $i=0; foreach ($_productCollection as $_product): ?>

FOR EACH PRODUCT LOAD BY SKU AND GET ATTRIBUTE INSIDE FOREACH

<?php
$product = Mage::getModel('catalog/product')->loadByAttribute('sku',$_product->getSku());
$author = $product['na_author'];
?>

<?php
if($author!=""){echo "<br /><span class='home_book_author'>By ".$author ."</span>";} else{echo "";}
?>

METHOD 2

Mage/Catalog/Block/Product/List.phtml OVER RIDE and set in 'local folder'

i.e. Copy From

Mage/Catalog/Block/Product/List.phtml

and PASTE TO

app/code/local/Mage/Catalog/Block/Product/List.phtml

change the function by adding 2 lines shown in bold below.

protected function _getProductCollection()
{
       if (is_null($this->_productCollection)) {
           $layer = Mage::getSingleton('catalog/layer');
           /* @var $layer Mage_Catalog_Model_Layer */
           if ($this->getShowRootCategory()) {
               $this->setCategoryId(Mage::app()->getStore()->getRootCategoryId());
           }

           // if this is a product view page
           if (Mage::registry('product')) {
               // get collection of categories this product is associated with
               $categories = Mage::registry('product')->getCategoryCollection()
                   ->setPage(1, 1)
                   ->load();
               // if the product is associated with any category
               if ($categories->count()) {
                   // show products from this category
                   $this->setCategoryId(current($categories->getIterator()));
               }
           }

           $origCategory = null;
           if ($this->getCategoryId()) {
               $category = Mage::getModel('catalog/category')->load($this->getCategoryId());

               if ($category->getId()) {
                   $origCategory = $layer->getCurrentCategory();
                   $layer->setCurrentCategory($category);
               }
           }
           $this->_productCollection = $layer->getProductCollection();

           $this->prepareSortableFieldsByCategory($layer->getCurrentCategory());

           if ($origCategory) {
               $layer->setCurrentCategory($origCategory);
           }
       }
       **//CMI-PK added na_author to filter on product listing page//
       $this->_productCollection->addAttributeToSelect('na_author');**
       return $this->_productCollection;

}

and you will be happy to see it....!!

The best solution that works for me without any problems looks this way:
1. Add temporary rule with some comment:

comment=$(cat /proc/sys/kernel/random/uuid | sed 's/\-//g')
iptables -A ..... -m comment --comment "${comment}" -j REQUIRED_ACTION

2. When the rule added and you wish to remove it (or everything with this comment), do:

iptables-save | grep -v "${comment}" | iptables-restore

So, you'll 100% delete all rules that match the $comment and leave other lines untouched. This solution works for last 2 months with about 100 changes of rules per day - no issues.Hope, it helps

Make sure you're entering "bundle" update, if you have the bundler gem installed.

bundle update

If you don't have bundler installed, do gem install bundler.

I would suggest adding class no-js to your html to nest your CSS selectors under it like:

.loading {
    display: none;
 }

.no-js .loading {
 display: block;
 //....
}

and when you finish loading your credit code remove it:

$('html').removeClass('no-js');

This will hide your loading spinner as there's no no-js class in html it means you already loaded your credit code

boolean compare(String str1, String str2) {
    if(str1==null || str2==null) {
        //return false; if you assume null not equal to null
        return str1==str2;
    }
    return str1.equals(str2);
}

is this what you desired?

 Date.now()

gives milliseconds since epoch. No need to use new.

Fix: Unlock your device before running it.

Hi Guys: Think I may have a fix for this:

Sounds ridiculous but try unlocking your Virtual Device; i.e. use your mouse to swipe and open. Your app should then work!!

Historically, Bourne shells didn't have true and false as built-in commands. true was instead simply aliased to :, and false to something like let 0.

: is slightly better than true for portability to ancient Bourne-derived shells. As a simple example, consider having neither the ! pipeline operator nor the || list operator (as was the case for some ancient Bourne shells). This leaves the else clause of the if statement as the only means for branching based on exit status:

if command; then :; else ...; fi

Since if requires a non-empty then clause and comments don't count as non-empty, : serves as a no-op.

Nowadays (that is: in a modern context) you can usually use either : or true. Both are specified by POSIX, and some find true easier to read. However there is one interesting difference: : is a so-called POSIX special built-in, whereas true is a regular built-in.

• Special built-ins are required to be built into the shell; Regular built-ins are only "typically" built in, but it isn't strictly guaranteed. There usually shouldn't be a regular program named : with the function of true in PATH of most systems.

• Probably the most crucial difference is that with special built-ins, any variable set by the built-in - even in the environment during simple command evaluation - persists after the command completes, as demonstrated here using ksh93:

  $ unset x; ( x=hi :; echo "$x" )
  hi
  $ ( x=hi true; echo "$x" )
  
  $
  

  Note that Zsh ignores this requirement, as does GNU Bash except when operating in POSIX compatibility mode, but all other major "POSIX sh derived" shells observe this including dash, ksh93, and mksh.

• Another difference is that regular built-ins must be compatible with exec - demonstrated here using Bash:

  $ ( exec : )
  -bash: exec: :: not found
  $ ( exec true )
  $
  

• POSIX also explicitly notes that : may be faster than true, though this is of course an implementation-specific detail.

Use the 'string' key of the hashmap, to access its value which is your tab class.

Tab mytab = hash.get("your_string_key_used_to_insert");

Open the workbook as hidden and then set it as "saved" so that users are not prompted when they close out.

Dim w As Workbooks

Private Sub Workbook_Open()
    Application.ScreenUpdating = False
    Set w = Workbooks
    w.Open Filename:="\\server\PriceList.xlsx", UpdateLinks:=False, ReadOnly:=True 'this is the data file were going to be opening
    ActiveWindow.Visible = False
    ThisWorkbook.Activate
    Application.ScreenUpdating = True
End Sub

Private Sub Workbook_BeforeClose(Cancel As Boolean)
    w.Item(2).Saved = True 'this will suppress the safe prompt for the data file only
End Sub

This is somewhat derivative of the answer posted by Ashok.

By doing it this way though you will not get prompted to save changes back to the Excel file your reading from. This is great if the Excel file your reading from is intended as a data source for validation. For example if the workbook contains product names and price data it can be hidden and you can show an Excel file that represents an invoice with drop downs for product that validates from that price list.

You can then store the price list on a shared location on a network somewhere and make it read-only.

I personally don't like atoi function. I would suggest sscanf:

char myarray[5] = {'-', '1', '2', '3', '\0'};
int i;
sscanf(myarray, "%d", &i);

It's very standard, it's in the stdio.h library :)

And in my opinion, it allows you much more freedom than atoi, arbitrary formatting of your number-string, and probably also allows for non-number characters at the end.

EDIT I just found this wonderful question here on the site that explains and compares 3 different ways to do it - atoi, sscanf and strtol. Also, there is a nice more-detailed insight into sscanf (actually, the whole family of *scanf functions).

EDIT2 Looks like it's not just me personally disliking the atoi function. Here's a link to an answer explaining that the atoi function is deprecated and should not be used in newer code.

In PL/SQL code, you can use: DBMS_OUTPUT.NEW_LINE;

Suppose you were only allowed to use array then you could find the size of 2-d array by the following way.

  int ary[][5] = { {1, 2, 3, 4, 5},
                   {6, 7, 8, 9, 0}
                 };

  int rows =  sizeof ary / sizeof ary[0]; // 2 rows  

  int cols = sizeof ary[0] / sizeof(int); // 5 cols

Pls check JobScheduler for apis above 26

WakeLock was the best option for this but it is deprecated in api level 26 Pls check this link if you consider api levels above 26
https://developer.android.com/reference/android/support/v4/content/WakefulBroadcastReceiver.html#startWakefulService(android.content.Context,%20android.content.Intent)

It says

As of Android O, background check restrictions make this class no longer generally useful. (It is generally not safe to start a service from the receipt of a broadcast, because you don't have any guarantees that your app is in the foreground at this point and thus allowed to do so.) Instead, developers should use android.app.job.JobScheduler to schedule a job, and this does not require that the app hold a wake lock while doing so (the system will take care of holding a wake lock for the job).

so as it says cosider JobScheduler
https://developer.android.com/reference/android/app/job/JobScheduler

if it is to do something than to start and to keep it you can receive the broadcast ACTION_BOOT_COMPLETED

If it isn't about foreground pls check if an Accessibility service could do

another option is to start an activity from broadcast receiver and finish it after starting the service within onCreate() , since newer android versions doesnot allows starting services from receivers

I'm a few years late, but why not this?

[Tt][Ee][Ss][Tt]

These examples seem a bit inefficient. Try this if you want to act upon the value:

<input id="cta" type="email" placeholder="Enter Email...">
<button onclick="return joinMailingList()">Join</button>

<script>
    const joinMailingList = () => {
        const email = document.querySelector('#cta').value
        console.log(email)
    }
</script>

You will encounter issue if you use this keyword with fat arrow (=>). If you need to do that, go old school:

<script>
    function joinMailingList() {
        const email = document.querySelector('#cta').value
        console.log(email)
    }
</script>

If you are working with password inputs, you should use type="password" so it will display ****** while the user is typing, and it is also more semantic.

I tried the same code with MATLAB 2011b with my MacBook Pro (Intel i7, 64 bit, 2.4 GHz) for the following MATLAB code:

% Processing time with Sorted data vs unsorted data
%==========================================================================
% Generate data
arraySize = 32768
sum = 0;
% Generate random integer data from range 0 to 255
data = randi(256, arraySize, 1);


%Sort the data
data1= sort(data); % data1= data  when no sorting done


%Start a stopwatch timer to measure the execution time
tic;

for i=1:100000

    for j=1:arraySize

        if data1(j)>=128
            sum=sum + data1(j);
        end
    end
end

toc;

ExeTimeWithSorting = toc - tic;

The results for the above MATLAB code are as follows:

  a: Elapsed time (without sorting) = 3479.880861 seconds.
  b: Elapsed time (with sorting ) = 2377.873098 seconds.

The results of the C code as in @GManNickG I get:

  a: Elapsed time (without sorting) = 19.8761 sec.
  b: Elapsed time (with sorting ) = 7.37778 sec.

Based on this, it looks MATLAB is almost 175 times slower than the C implementation without sorting and 350 times slower with sorting. In other words, the effect (of branch prediction) is 1.46x for MATLAB implementation and 2.7x for the C implementation.

You need to add else in your lambda function. Because you are telling what to do in case your condition(here x < 90) is met, but you are not telling what to do in case the condition is not met.

sample['PR'] = sample['PR'].apply(lambda x: 'NaN' if x < 90 else x) 

In PySpark you can use a dataframe and set header as True:

df = spark.read.csv(dataPath, header=True)

I've never done it, but it looks like Reflection provides this. Field is an AnnotatedElement and so it has getAnnotation. This page has an example (copied below); quite straightforward if you know the class of the annotation and if the annotation policy retains the annotation at runtime. Naturally if the retention policy doesn't keep the annotation at runtime, you won't be able to query it at runtime.

An answer that's since been deleted (?) provided a useful link to an annotations tutorial that you may find helpful; I've copied the link here so people can use it.

Example from this page:

import java.lang.annotation.Retention; 
import java.lang.annotation.RetentionPolicy;
import java.lang.reflect.Method;

@Retention(RetentionPolicy.RUNTIME)
@interface MyAnno {
  String str();

  int val();
}

class Meta {
  @MyAnno(str = "Two Parameters", val = 19)
  public static void myMeth(String str, int i) {
    Meta ob = new Meta();

    try {
      Class c = ob.getClass();

      Method m = c.getMethod("myMeth", String.class, int.class);

      MyAnno anno = m.getAnnotation(MyAnno.class);

      System.out.println(anno.str() + " " + anno.val());
    } catch (NoSuchMethodException exc) {
      System.out.println("Method Not Found.");
    }
  }

  public static void main(String args[]) {
    myMeth("test", 10);
  }
}

You can convert json Object into Array & String using PHP.

$data='{"resultList":[{"id":"1839","displayName":"Analytics","subLine":""},{"id":"1015","displayName":"Automation","subLine":""},{"id":"1084","displayName":"Aviation","subLine":""},{"id":"554","displayName":"Apparel","subLine":""},{"id":"875","displayName":"Aerospace","subLine":""},{"id":"1990","displayName":"Account Reconciliation","subLine":""},{"id":"3657","displayName":"Android","subLine":""},{"id":"1262","displayName":"Apache","subLine":""},{"id":"1440","displayName":"Acting","subLine":""},{"id":"710","displayName":"Aircraft","subLine":""},{"id":"12187","displayName":"AAC","subLine":""}, {"id":"20365","displayName":"AAT","subLine":""}, {"id":"7849","displayName":"AAP","subLine":""}, {"id":"20511","displayName":"AACR2","subLine":""}, {"id":"28585","displayName":"AASHTO","subLine":""}, {"id":"45191","displayName":"AAMS","subLine":""}]}';

$b=json_decode($data);

$i=0;
while($b->{'resultList'}[$i])
{
    print_r($b->{'resultList'}[$i]->{'displayName'});
    echo "<br />";
    $i++;
}

You are using a function for which the compiler has not seen a declaration ("prototype") yet.

For example:

int main()
{
    fun(2, "21"); /* The compiler has not seen the declaration. */       
    return 0;
}

int fun(int x, char *p)
{
    /* ... */
}

You need to declare your function before main, like this, either directly or in a header:

int fun(int x, char *p);

In case you don't want to track table view's content size changes yourself, you might find this subclass useful.

protocol ContentFittingTableViewDelegate: UITableViewDelegate {
    func tableViewDidUpdateContentSize(_ tableView: UITableView)
}

class ContentFittingTableView: UITableView {

    override var contentSize: CGSize {
        didSet {
            if !constraints.isEmpty {
                invalidateIntrinsicContentSize()
            } else {
                sizeToFit()
            }

            if contentSize != oldValue {
                if let delegate = delegate as? ContentFittingTableViewDelegate {
                    delegate.tableViewDidUpdateContentSize(self)
                }
            }
        }
    }

    override var intrinsicContentSize: CGSize {
        return contentSize
    }

    override func sizeThatFits(_ size: CGSize) -> CGSize {
        return contentSize
    }
}

Retrieve a specific type of file

This example will get a copy of the image.

static final int REQUEST_IMAGE_GET = 1;

public void selectImage() {
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
    intent.setType("image/*");
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivityForResult(intent, REQUEST_IMAGE_GET);
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_IMAGE_GET && resultCode == RESULT_OK) {
        Bitmap thumbnail = data.getParcelable("data");
        Uri fullPhotoUri = data.getData();
        // Do work with photo saved at fullPhotoUri
        ...
    }
}

Open a specific type of file

When running on 4.4 or higher, you request to open a file that's managed by another app

static final int REQUEST_IMAGE_OPEN = 1;

public void selectImage() {
    Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
    intent.setType("image/*");
    intent.addCategory(Intent.CATEGORY_OPENABLE);
    // Only the system receives the ACTION_OPEN_DOCUMENT, so no need to test.
    startActivityForResult(intent, REQUEST_IMAGE_OPEN);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_IMAGE_OPEN && resultCode == RESULT_OK) {
        Uri fullPhotoUri = data.getData();
        // Do work with full size photo saved at fullPhotoUri
        ...
    }
}

Original source

by using jquery to register .mousemove to document to change the image .css left and top to event.pageX and event.pageY.

example as below http://jsfiddle.net/BfLAh/1/

$(document).mousemove(function(e) {
  $("#follow").css({
    left: e.pageX,
    top: e.pageY
  });
});

#follow {
  position: absolute;
  text-align: center;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="follow"><img src="https://placekitten.com/96/140" /><br>Kitteh</br>
</div>

updated to follow slowly

http://jsfiddle.net/BfLAh/3/

for the orientation , you need to get the current css left and css top and compare with event.pageX and event.pageY , then set the image orientation with

-webkit-transform: rotate(-90deg); 
-moz-transform: rotate(-90deg); 

for the speed , you can set the jquery .animation duration to certain amount.

HTTP Authorization header problem can be addressed with the following:

var ws = new WebSocket("ws://username:[email protected]/service");

Then, a proper Basic Authorization HTTP header will be set with the provided username and password. If you need Basic Authorization, then you're all set.

I want to use Bearer however, and I resorted to the following trick: I connect to the server as follows:

var ws = new WebSocket("ws://[email protected]/service");

And when my code at the server side receives Basic Authorization header with non-empty username and empty password, then it interprets the username as a token.

While it may be completely valid HTML to not include an href, especially with an onclick handler, there are some things to consider: it will not be keyboard-focusable without having a tabindex value set. Furthermore, this will be inaccessible to screenreader software using Internet Explorer, as IE will report through the accessibility interfaces that any anchor element without an href attribute as not-focusable, regardless of whether the tabindex has been set.

So while the following may be completely valid:

<a class="arrow">Link content</a>

It's far better to explicitly add a null-effect href attribute

<a href="javascript:void(0);" class="arrow">Link content</a>

For full support of all users, if you're using the class with CSS to render an image, you should also include some text content, such as the title attribute to provide a textual description of what's going on.

<a href="javascript:void(0);" class="arrow" title="Go to linked content">Link content</a>

Try the sp_foreachdb procedure.

Make sure that mWakeLock isn't accidentally cleaned up before you're ready to release it. If it's finalized, the lock is released. This can happen, for example, if you set it to null and the garbage collector subsequently runs. It can also happen if you accidentally set a local variable of the same name instead of the method-level variable.

I'd also recommend checking LogCat for entries that have the PowerManagerService tag or the tag that you pass to newWakeLock.

Assuming no SecurityManager is preventing you from doing this, you can use setAccessible to get around private and resetting the modifier to get rid of final, and actually modify a private static final field.

Here's an example:

import java.lang.reflect.*;

public class EverythingIsTrue {
   static void setFinalStatic(Field field, Object newValue) throws Exception {
      field.setAccessible(true);

      Field modifiersField = Field.class.getDeclaredField("modifiers");
      modifiersField.setAccessible(true);
      modifiersField.setInt(field, field.getModifiers() & ~Modifier.FINAL);

      field.set(null, newValue);
   }
   public static void main(String args[]) throws Exception {      
      setFinalStatic(Boolean.class.getField("FALSE"), true);

      System.out.format("Everything is %s", false); // "Everything is true"
   }
}

Assuming no SecurityException is thrown, the above code prints "Everything is true".

What's actually done here is as follows:

• The primitive boolean values true and false in main are autoboxed to reference type Boolean "constants" Boolean.TRUE and Boolean.FALSE
• Reflection is used to change the public static final Boolean.FALSE to refer to the Boolean referred to by Boolean.TRUE
• As a result, subsequently whenever a false is autoboxed to Boolean.FALSE, it refers to the same Boolean as the one refered to by Boolean.TRUE
• Everything that was "false" now is "true"

Caveats

Extreme care should be taken whenever you do something like this. It may not work because a SecurityManager may be present, but even if it doesn't, depending on usage pattern, it may or may not work.

JLS 17.5.3 Subsequent Modification of Final Fields

In some cases, such as deserialization, the system will need to change the final fields of an object after construction. final fields can be changed via reflection and other implementation dependent means. The only pattern in which this has reasonable semantics is one in which an object is constructed and then the final fields of the object are updated. The object should not be made visible to other threads, nor should the final fields be read, until all updates to the final fields of the object are complete. Freezes of a final field occur both at the end of the constructor in which the final field is set, and immediately after each modification of a final field via reflection or other special mechanism.

Even then, there are a number of complications. If a final field is initialized to a compile-time constant in the field declaration, changes to the final field may not be observed, since uses of that final field are replaced at compile time with the compile-time constant.

Another problem is that the specification allows aggressive optimization of final fields. Within a thread, it is permissible to reorder reads of a final field with those modifications of a final field that do not take place in the constructor.

See also

• JLS 15.28 Constant Expression
  • It's unlikely that this technique works with a primitive private static final boolean, because it's inlineable as a compile-time constant and thus the "new" value may not be observable

Appendix: On the bitwise manipulation

Essentially,

field.getModifiers() & ~Modifier.FINAL

turns off the bit corresponding to Modifier.FINAL from field.getModifiers(). & is the bitwise-and, and ~ is the bitwise-complement.

Remember Constant Expressions

Still not being able to solve this?, have fallen onto depression like I did for it? Does your code looks like this?

public class A {
    private final String myVar = "Some Value";
}

Reading the comments on this answer, specially the one by @Pshemo, it reminded me that Constant Expressions are handled different so it will be impossible to modify it. Hence you will need to change your code to look like this:

public class A {
    private final String myVar;

    private A() {
        myVar = "Some Value";
    }
}

if you are not the owner of the class... I feel you!

For more details about why this behavior read this?

In order to do this you need to attach the handler to a specific anchor on the page. For operations like this it's much easier to use a standard framework like jQuery. For example if I had the following HTML

HTML:

<a id="theLink">Click Me</a>

I could use the following jQuery to hookup an event to that specific link.

// Use ready to ensure document is loaded before running javascript
$(document).ready(function() {

  // The '#theLink' portion is a selector which matches a DOM element
  // with the id 'theLink' and .click registers a call back for the 
  // element being clicked on 
  $('#theLink').click(function (event) {

    // This stops the link from actually being followed which is the 
    // default action 
    event.preventDefault();

    var answer confirm("Please click OK to continue");
    if (!answer) {
      window.location="http://www.continue.com"
    }
  });

});

Use a BigDecimal instead of float/double. There are a lot of numbers which can't be represented as binary floating point (for example, 0.1). So you either must always round the result to a known precision or use BigDecimal.

See http://en.wikipedia.org/wiki/Floating_point for more information.

I spent a long time figuring out the answer to this, but I finally got it (and it's actually really simple):

import sys
import os
sys.path.append(os.getcwd() + '/your/subfolder/of/choice')

# now import whatever other modules you want, both the standard ones,
# as the ones supplied in your subfolders

This will append the relative path of your subfolder to the directories for python to look in It's pretty quick and dirty, but it works like a charm :)

Note that on some devices your code wont work without android:priority="1000" in intent filter:

<receiver android:name=".listener.SmsListener">
    <intent-filter android:priority="1000">
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

And here is some optimizations:

public class SmsListener extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        if (Telephony.Sms.Intents.SMS_RECEIVED_ACTION.equals(intent.getAction())) {
            for (SmsMessage smsMessage : Telephony.Sms.Intents.getMessagesFromIntent(intent)) {
                String messageBody = smsMessage.getMessageBody();
            }
        }
    }
}

Note:
The value must be an integer, such as "100". Higher numbers have a higher priority. The default value is 0. The value must be greater than -1000 and less than 1000.

Personally, I think the "Big Bang" was caused when two GUIDs collided.

For loading weights, you need to have a model first. It must be:

existingModel.save_weights('weightsfile.h5')
existingModel.load_weights('weightsfile.h5')     

If you want to save and load the entire model (this includes the model's configuration, it's weights and the optimizer states for further training):

model.save_model('filename')
model = load_model('filename')

If you use ng > 1.2, here is an example of using ng-repeat-start/end without generating unnecessary tags:

<html>_x000D_
  <head>_x000D_
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
    <script>_x000D_
      angular.module('mApp', []);_x000D_
    </script>_x000D_
  </head>_x000D_
  <body ng-app="mApp">_x000D_
    <table border="1" width="100%">_x000D_
      <tr ng-if="0" ng-repeat-start="elem in [{k: 'A', v: ['a1','a2']}, {k: 'B', v: ['b1']}, {k: 'C', v: ['c1','c2','c3']}]"></tr>_x000D_
_x000D_
      <tr>_x000D_
        <td rowspan="{{elem.v.length}}">{{elem.k}}</td>_x000D_
        <td>{{elem.v[0]}}</td>_x000D_
      </tr>_x000D_
      <tr ng-repeat="v in elem.v" ng-if="!$first">_x000D_
        <td>{{v}}</td>_x000D_
      </tr>_x000D_
_x000D_
      <tr ng-if="0" ng-repeat-end></tr>_x000D_
    </table>_x000D_
  </body>_x000D_
</html>

The important point: for tags used for ng-repeat-start and ng-repeat-end set ng-if="0", to let not be inserted in the page. In this way the inner content will be handled exactly as it is in knockoutjs (using commands in <!--...-->), and there will be no garbage.

None of the answers to date mention the effect of the innodb_page_size parameter. Possibly because changing this parameter was not a supported operation prior to MySQL 5.7.6. From the documentation:

The maximum row length, except for variable-length columns (VARBINARY, VARCHAR, BLOB and TEXT), is slightly less than half of a database page for 4KB, 8KB, 16KB, and 32KB page sizes. For example, the maximum row length for the default innodb_page_size of 16KB is about 8000 bytes. For an InnoDB page size of 64KB, the maximum row length is about 16000 bytes. LONGBLOB and LONGTEXT columns must be less than 4GB, and the total row length, including BLOB and TEXT columns, must be less than 4GB.

Note that increasing the page size is not without its drawbacks. Again from the documentation:

As of MySQL 5.7.6, 32KB and 64KB page sizes are supported but ROW_FORMAT=COMPRESSED is still unsupported for page sizes greater than 16KB. For both 32KB and 64KB page sizes, the maximum record size is 16KB. For innodb_page_size=32k, extent size is 2MB. For innodb_page_size=64k, extent size is 4MB.

A MySQL instance using a particular InnoDB page size cannot use data files or log files from an instance that uses a different page size. This limitation could affect restore or downgrade operations using data from MySQL 5.6, which does support page sizes other than 16KB.

First, it's always worth noting that git reset --hard is a potentially dangerous command, since it throws away all your uncommitted changes. For safety, you should always check that the output of git status is clean (that is, empty) before using it.

Initially you say the following:

So I know that Git tracks changes I make to my application, and it holds on to them until I commit the changes, but here's where I'm hung up:

That's incorrect. Git only records the state of the files when you stage them (with git add) or when you create a commit. Once you've created a commit which has your project files in a particular state, they're very safe, but until then Git's not really "tracking changes" to your files. (for example, even if you do git add to stage a new version of the file, that overwrites the previously staged version of that file in the staging area.)

In your question you then go on to ask the following:

When I want to revert to a previous commit I use: git reset --hard HEAD And git returns: HEAD is now at 820f417 micro

How do I then revert the files on my hard drive back to that previous commit?

If you do git reset --hard <SOME-COMMIT> then Git will:

• Make your current branch (typically master) back to point at <SOME-COMMIT>.
• Then make the files in your working tree and the index ("staging area") the same as the versions committed in <SOME-COMMIT>.

HEAD points to your current branch (or current commit), so all that git reset --hard HEAD will do is to throw away any uncommitted changes you have.

So, suppose the good commit that you want to go back to is f414f31. (You can find that via git log or any history browser.) You then have a few different options depending on exactly what you want to do:

• Change your current branch to point to the older commit instead. You could do that with git reset --hard f414f31. However, this is rewriting the history of your branch, so you should avoid it if you've shared this branch with anyone. Also, the commits you did after f414f31 will no longer be in the history of your master branch.

• Create a new commit that represents exactly the same state of the project as f414f31, but just adds that on to the history, so you don't lose any history. You can do that using the steps suggested in this answer - something like:

  git reset --hard f414f31
  git reset --soft HEAD@{1}
  git commit -m "Reverting to the state of the project at f414f31"
  

<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
android:paddingLeft="0dp">

This should be good enough.

I agree with BMSAndroidDroid and Flo-Scheild-Bobby. I was doing a tutorial called DailyQuote and had used the Cordova library. I then changed my OS from Windows to Ubuntu and tried to import projects into Eclipse, (I'm using Eclipse Juno 64-bit, on Ubuntu 12.04 64-bit, Oracle JDK 7. I also installed the Ubuntu 32-bit libs- so no issues with 64 and 32bit), and got the same issue.

As suggested by Flo-Scheild-Bobby, open configure build path and add the jar(s) again that you added before. Then remove the old jar link(s) and thats it.

You ca also use Response.Write("alert('Error')");

For the benefit of anyone else reading this question that really is missing print statements from their output, there actually are cases where the print executes but is not returned to the client. I can't tell you specifically what they are. I can tell you that if put a go statement immediately before and after any print statement, you will see it if it is executed.

pluginManagement: is an element that is seen along side plugins. Plugin Management contains plugin elements in much the same way, except that rather than configuring plugin information for this particular project build, it is intended to configure project builds that inherit from this one. However, this only configures plugins that are actually referenced within the plugins element in the children. The children have every right to override pluginManagement definitions.

If you want exactly 40 spaces before the string then you should just do:

printf("                                        %s\n", myStr );

If that is too dirty, you can do (but it will be slower than manually typing the 40 spaces): printf("%40s%s", "", myStr );

If you want the string to be lined up at column 40 (that is, have up to 39 spaces proceeding it such that the right most character is in column 40) then do this: printf("%40s", myStr);

You can also put "up to" 40 spaces AfTER the string by doing: printf("%-40s", myStr);

The error is also caused by quirky handling of quotes and single qutoes. To include single quotes inside the query, use doubled single quotes.

This won't work

select dbms_xmlgen.getxml("Select ....") XML from dual;

or this either

select dbms_xmlgen.getxml('Select .. where something='red'..') XML from dual;

but this DOES work

select dbms_xmlgen.getxml('Select .. where something=''red''..') XML from dual;

If the LINQ query is executed in database context, a call to Contains() is mapped to the LIKE operator:

.Where(a => a.Field.Contains("hello")) becomes Field LIKE '%hello%'. The LIKE operator is case insensitive by default, but that can be changed by changing the collation of the column.

If the LINQ query is executed in .NET context, you can use IndexOf(), but that method is not supported in LINQ to SQL.

LINQ to SQL does not support methods that take a CultureInfo as parameter, probably because it can not guarantee that the SQL server handles cultures the same as .NET. This is not completely true, because it does support StartsWith(string, StringComparison).

However, it does not seem to support a method which evaluates to LIKE in LINQ to SQL, and to a case insensitive comparison in .NET, making it impossible to do case insensitive Contains() in a consistent way.

A wild card would work nicely for this, although to be safe it would be best to make the use of the wild card as minimal as possible, so something along the lines of this:

rm -rf abc.log.2012-*

Although from the looks of it, are those just single files? The recursive option should not be necessary if none of those items are directories, so best to not use that, just for safety.

You have a couple of questions here, so I'll address them separately:

I need to store a number of selected items in one field in a database

My general rule is: don't. This is something which all but requires a second table (or third) with a foreign key. Sure, it may seem easier now, but what if the use case comes along where you need to actually query for those items individually? It also means that you have more options for lazy instantiation and you have a more consistent experience across multiple frameworks/languages. Further, you are less likely to have connection timeout issues (30,000 characters is a lot).

You mentioned that you were thinking about using ENUM. Are these values fixed? Do you know them ahead of time? If so this would be my structure:

Base table (what you have now):

| id primary_key sequence
| -- other columns here.

Items table:

| id primary_key sequence
| descript VARCHAR(30) UNIQUE

Map table:

| base_id  bigint
| items_id bigint

Map table would have foreign keys so base_id maps to Base table, and items_id would map to the items table.

And if you'd like an easy way to retrieve this from a DB, then create a view which does the joins. You can even create insert and update rules so that you're practically only dealing with one table.

What format should I use store the data?

If you have to do something like this, why not just use a character delineated string? It will take less processing power than a CSV, XML, or JSON, and it will be shorter.

What column type should I use store the data?

Personally, I would use TEXT. It does not sound like you'd gain much by making this a BLOB, and TEXT, in my experience, is easier to read if you're using some form of IDE.

Follow these steps:

1) Install:

npm install react-scroll-to --save

2) Import the package:

import { ScrollTo } from "react-scroll-to";

3) Usage:

class doc extends Component {
  render() {
    return(
      <ScrollTo>
        {({ scroll }) => (
          <a onClick={() => scroll({ x: 20, y: 500, , smooth: true })}>Scroll to Bottom</a>
        )}
      </ScrollTo>
    )
  }
}

To sort the array by the value of the "title" key use:

uasort($myArray, function($a, $b) {
    return strcmp($a['title'], $b['title']);
});

strcmp compare the strings.

uasort() maintains the array keys as they were defined.

I know it's equal to sizeof(int). The size of an int is really compiler dependent. Back in the day, when processors were 16 bit, an int was 2 bytes. Nowadays, it's most often 4 bytes on a 32-bit as well as 64-bit systems.

Still, using sizeof(int) is the best way to get the size of an integer for the specific system the program is executed on.

EDIT: Fixed wrong statement that int is 8 bytes on most 64-bit systems. For example, it is 4 bytes on 64-bit GCC.

Try this one:

System.DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss")

Following this doc you can do this that way:

{{ p.User['first_name']|default('NONE') }}

Since Java 1.7 you can use Files.createFile:

Path pathToFile = Paths.get("/home/joe/foo/bar/myFile.txt");
Files.createDirectories(pathToFile.getParent());
Files.createFile(pathToFile);

It might be a lot easier than all that. If you want your page to load then check on the availability or content of some foreign page to trigger other web page activity, you could do it using only javascript and php like this.

yourpage.php

<?php
if (isset($_GET['urlget'])){
  if ($_GET['urlget']!=''){
    $foreignpage= file_get_contents('http://www.foreignpage.html');
    // you could also use curl for more fancy internet queries or if http wrappers aren't active in your php.ini
    // parse $foreignpage for data that indicates your page should proceed
    echo $foreignpage; // or a portion of it as you parsed
    exit();  // this is very important  otherwise you'll get the contents of your own page returned back to you on each call
  }
}
?>

<html>
  mypage html content
  ...

<script>
var stopmelater= setInterval("getforeignurl('?urlget=doesntmatter')", 2000);

function getforeignurl(url){
  var handle= browserspec();
  handle.open('GET', url, false);
  handle.send();
  var returnedPageContents= handle.responseText;
  // parse page contents for what your looking and trigger javascript events accordingly.
  // use handle.open('GET', url, true) to allow javascript to continue executing. must provide a callback function to accept the page contents with handle.onreadystatechange()
}
function browserspec(){
  if (window.XMLHttpRequest){
    return new XMLHttpRequest();
  }else{
    return new ActiveXObject("Microsoft.XMLHTTP");
  }
}

</script>

That should do it.

The triggered javascript should include clearInterval(stopmelater)

Let me know if that works for you

although Response::json() is not getting popular of recent, that does not stop you and Me from using it. In fact you don't need any facade to use it,

instead of:

$response = Response::json($messages, 200);

Use this:

$response = \Response::json($messages, 200);

with the slash, you are sure good to go.

Greg is absolutely correct. This kind of parsing cannot be done with regular expressions. I suppose it is possible to build some horrendous monstrosity that would work for many cases, but then you'll just run across something that does.

You really need to use more traditional parsing techniques. For example, its pretty simple to write a recursive decent parser to do what you need.

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status === 500) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 400) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 409) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 406) {
                    return Observable.throw(new Error(error.status));
                }
            });
    }

also you can handel error (with err block) that is throw by catch block while .map function,

like this -

...
.subscribe(res=>{....}
           err => {//handel here});

Update

as required for any status without checking particluar one you can try this: -

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status < 400 ||  error.status ===500) {
                    return Observable.throw(new Error(error.status));
                }
            })
            .subscribe(res => {...},
                       err => {console.log(err)} );

Instead of using list.index(x) which returns the index of x if it is found in list or returns a #ValueError message if x is not found, you could use list.count(x) which returns the number of occurrences of x in list (validation that x is indeed in the list) or it returns 0 otherwise (in the absence of x). The cool thing about count() is that it doesn't break your code or require you to throw an exception for when x is not found

Either add an event listener, or have the image announce itself with onload. Then figure out the dimensions from there.

<img id="photo"
     onload='loaded(this.id)'
     src="a_really_big_file.jpg"
     alt="this is some alt text"
     title="this is some title text" />

Load data infile query is much better option but some servers like godaddy restrict this option on shared hosting so , only two options left then one is insert record on every iteration or batch insert , but batch insert has its limitaion of characters if your query exceeds this number of characters set in mysql then your query will crash , So I suggest insert data in chunks withs batch insert , this will minimize number of connections established with database.best of luck guys

In ANSI SQL, double quotes quote object names (e.g. tables) which allows them to contain characters not otherwise permitted, or be the same as reserved words (Avoid this, really).

Single quotes are for strings.

However, MySQL is oblivious to the standard (unless its SQL_MODE is changed) and allows them to be used interchangably for strings.

Moreover, Sybase and Microsoft also use square brackets for identifier quoting.

So it's a bit vendor specific.

Other databases such as Postgres and IBM actually adhere to the ansi standard :)

I will assume that you've done a data dump as insert statements, and you (or whoever Googles this) are attempting to figure out the date and time, or translate it for use elsewhere (eg: to convert to MySQL inserts). This is actually easy in any programming language.

Let's work with this:

CAST(0x0000A61300B1F1EB AS DateTime)

This Hex representation is actually two separate data elements... Date and Time. The first four bytes are date, the second four bytes are time.

• The date is 0x0000A613
• The time is 0x00B1F1EB

Convert both of the segments to integers using the programming language of your choice (it's a direct hex to integer conversion, which is supported in every modern programming language, so, I will not waste space with code that may or may not be the programming language you're working in).

• The date of 0x0000A613 becomes 42515
• The time of 0x00B1F1EB becomes 11661803

Now, what to do with those integers:

Date

Date is since 01/01/1900, and is represented as days. So, add 42,515 days to 01/01/1900, and your result is 05/27/2016.

Time

Time is a little more complex. Take that INT and do the following to get your time in microseconds since midnight (pseudocode):

TimeINT=Hex2Int(HexTime)
MicrosecondsTime = TimeINT*10000/3

From there, use your language's favorite function calls to translate microseconds (38872676666.7 µs in the example above) into time.

The result would be 10:47:52.677

If you are on version >= Android 8.1 (Oreo) while using a Notification channel, set its importance to high:

int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name, importance);

Consider adding this to your CSS to resolve the problem:

.btn {
  width: 20%;
  margin-left: 40%;
  margin-right: 30%;
}

Apart from what is being mentioned above, .uniform() can also be used for generating multiple random numbers that too with the desired shape which is not possible with .random()

np.random.seed(99)
np.random.random()

#generates 0.6722785586307918

while the following code

np.random.seed(99)
np.random.uniform(0.0, 1.0, size = (5,2))

#generates this 
array([[0.67227856, 0.4880784 ],
       [0.82549517, 0.03144639],
       [0.80804996, 0.56561742],
       [0.2976225 , 0.04669572],
       [0.9906274 , 0.00682573]])

This can't be done with random(...), and if you're generating the random(...) numbers for ML related things, most of the time, you'll end up using .uniform(...)

Although this is the accepted answer, toto_tico's answer below is better :)

Try making the onclick js use 'return' to ensure the desired return value gets used...

<button type="button" value="click me" onclick="return check_me();" />

You said you are attempting to get the text from a div and store it on local storage.

Please Note: Text and Html are different. In the question you mentioned text. html() will return Html content like <a>example</a>. if you want to get Text content then you have to use text() instead of html() then the result will be example instead of <a>example<a>. Anyway, I am using your terminology let it be Text.

Step 1: get the text from div.

what you did is not get the text from div but set the text to a div.

$('#test').html("Test"); 

is actually setting text to div and the output will be a jQuery object. That is why it sets it as [object Object].

To get the text you have to write like this
$('#test').html();

This will return a string not an object so the result will be Test in your case.

Step 2: set it to local storage.

Your approach is correct and you can write it as

localStorage.key=value

But the preferred approach is

localStorage.setItem(key,value); to set

localStorage.getItem(key); to get.

key and value must be strings.

so in your context code will become

$('#test').html("Test");
localStorage.content = $('#test').html();
$('#test').html(localStorage.content);

But I don't find any meaning in your code. Because you want to get the text from div and store it on local storage. And again you are reading the same from local storage and set to div. just like a=10; b=a; a=b;

If you are facing any other problems please update your question accordingly.

You can add a RedirectViewController like:

@Configuration
public class WebConfiguration implements WebMvcConfigurer {

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addRedirectViewController("/", "/index.html");
    }
}

List<Map<String, Object>> List = getJdbcTemplate().queryForList(SELECT_ALL_CONVERSATIONS_SQL_FULL, new Object[] {userId, dateFrom, dateTo});
for (Map<String, Object> rowMap : resultList) {
    DTO dTO = new DTO();
    dTO.setrarchyID((Long) (rowMap.get("ID")));
}

These are the default settings I have for /etc/network/interfaces (including WiFi settings) for my Raspberry Pi 1:

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0

You need to put your main code on the OnStart method.

This other SO answer of mine might help.

You will need to put some code to enable debugging within visual-studio while maintaining your application valid as a windows-service. This other SO thread cover the issue of debugging a windows-service.

EDIT:

Please see also the documentation available here for the OnStart method at the MSDN where one can read this:

Do not use the constructor to perform processing that should be in OnStart. Use OnStart to handle all initialization of your service. The constructor is called when the application's executable runs, not when the service runs. The executable runs before OnStart. When you continue, for example, the constructor is not called again because the SCM already holds the object in memory. If OnStop releases resources allocated in the constructor rather than in OnStart, the needed resources would not be created again the second time the service is called.

I would recommend DISLIN. It's cross platform, has support for many languages, and has very intuitive naming of routines.

Also, just noticed that nobody mentioned PLPLOT, also cross platform, multi lingual ...

Callbacks are about signals and "new" is about creating object instances.

In this case it would be even more appropriate to execute just "callback();" than "return new callback()" because you aren't doing anything with a return value anyway.

(And the arguments.length==3 test is really clunky, fwiw, better to check that callback param exists and is a function.)

UPDATE 17/03/2017

Original solution won't work anymore. The spinners are part of shadow dom. For now just to hide in chrome use:

input[type=number]::-webkit-inner-spin-button {_x000D_
  -webkit-appearance: none;_x000D_
}

<input type="number" />

or to always show:

input[type=number]::-webkit-inner-spin-button {_x000D_
  opacity: 1;_x000D_
}

<input type="number" />

You can try the following but keep in mind that works only for Chrome:

input[type=number]::-webkit-inner-spin-button { _x000D_
    -webkit-appearance: none;_x000D_
    cursor:pointer;_x000D_
    display:block;_x000D_
    width:8px;_x000D_
    color: #333;_x000D_
    text-align:center;_x000D_
    position:relative;_x000D_
}_x000D_
_x000D_
input[type=number]::-webkit-inner-spin-button:before,_x000D_
input[type=number]::-webkit-inner-spin-button:after {_x000D_
    content: "^";_x000D_
    position:absolute;_x000D_
    right: 0;_x000D_
}_x000D_
_x000D_
input[type=number]::-webkit-inner-spin-button:before {_x000D_
    top:0px;_x000D_
}_x000D_
_x000D_
input[type=number]::-webkit-inner-spin-button:after {_x000D_
    bottom:0px;_x000D_
    -webkit-transform: rotate(180deg);_x000D_
}

<input type="number" />

If you add ?__a=1 at the end of Instagram public URLs, you get the data of the public URL in JSON.

For the media ID of an image from post URL, simply add the JSON request code at the post URL:

The only way I can think of for short texts like "MENU" is to put every single letter in a span and justify them in a container afterwards. Like this:

<div class="menu-burger">
  <span></span>
  <span></span>
  <span></span>
  <div>
    <span>M</span>
    <span>E</span>
    <span>N</span>
    <span>U</span>
  </div>
</div>

And then the CSS:

.menu-burger {
  width: 50px;
  height: 50px;
  padding: 5px;
}

...

.menu-burger > div {
  display: flex;
  justify-content: space-between;
}

I received this error while trying to run Google's Firebase analytics sample app:

Prerequisites:

• Download https://github.com/firebase/quickstart-android
• Add quickstart/analytics to Android Studio

Add Procedure:

1. Go to https://firebase.google.com/
2. Click on "GO TO CONSOLE"
3. Click on "Add Project"
4. Project name: Enter: sample-app
5. Click "Create Project" [Takes about 10 seconds or so...]
6. Click "Continue"
7. On the "Getting Started" page, click "Add Firebase to your Android app"
8. Enter package name for the android app [The full package name appears at the top of the manifest: "com.google.firebase.quickstart.analytics"]
9. Click on download google-services.json
10. In file explorer, add google-services.json to the directory: "quickstart/analytics/app" [Warning: Do not rename the file, it must be: google-services.json]
11. Run 'app'
    • The sample app already contains the necessary Gradle file settings.
    • When adding a new project do: Tools -> Firebase -> Analytics -> Add Event -> Connect App to Firebase.
    • Adding a project via Android Studio ensures that all the Gradle Dependecies are setup.

Remove Procedure:

1. Go to https://firebase.google.com/
2. Click on "GO TO CONSOLE"
3. Settings -> Project Settings -> Delete this App
4. Settings -> Project Settings -> Delete Project
5. Enter project ID and press delete

I added and removed the sample app multiple times without any noticeable side effects.

After hours of struggle with no solution here, this worked for me then I found a youtube video where it says the password column is now called authentication_string . So I was able to change my password as follows: First get into mysql from terminal

sudo mysql

then inside mysql type whatever after mysql>

mysql> use mysql
mysql> update user set authentication_string=PASSWORD("mypass") where user='root';
mysql> flush privileges;
mysql> quit;

at this point you are out of mysql back to your normal terminal place. You need to restart mysql for this to take effect. for that type the following:

sudo service mysql restart

Refer to this video link for better understanding

you need to give width explicitly to header and footer

width: 100%;

Working fiddle

If you want the middle section not to be hidden then give position: absolute;width: 100%; and set top and bottom properties (related to header and footer heights) to it and give parent element position: relative. (ofcourse, remove height: 700px;.) and to make it scrollable, give overflow: auto.

transition-property:width;

This should work. you have to have browser dependent code

Since you're scanning the whole string anyway you can build a full character count and do any number of lookups, all for the same big-Oh cost (n):

public static Map<Character,Integer> getCharFreq(String s) {
  Map<Character,Integer> charFreq = new HashMap<Character,Integer>();
  if (s != null) {
    for (Character c : s.toCharArray()) {
      Integer count = charFreq.get(c);
      int newCount = (count==null ? 1 : count+1);
      charFreq.put(c, newCount);
    }
  }
  return charFreq;
}

// ...
String s = "abdsd3$asda$asasdd$sadas";
Map counts = getCharFreq(s);
counts.get('$'); // => 3
counts.get('a'); // => 7
counts.get('s'); // => 6

Using angular 1.5.9

I made it working like this by setting the window.location to the csv file download url. Tested and its working with the latest version of Chrome and IE11.

Angular

   $scope.downloadStats = function downloadStats{
        var csvFileRoute = '/stats/download';
        $window.location = url;
    }

html

<a target="_self" ng-click="downloadStats()"><i class="fa fa-download"></i> CSV</a>

In php set the below headers for the response:

$headers = [
    'content-type'              => 'text/csv',
    'Content-Disposition'       => 'attachment; filename="export.csv"',
    'Cache-control'             => 'private, must-revalidate, post-check=0, pre-check=0',
    'Content-transfer-encoding' => 'binary',
    'Expires' => '0',
    'Pragma' => 'public',
];

So interestingly enough this error "Transport endpoint is not connected" was caused by my having more than one Veracrypt device mounted. I closed the extra device and suddenly I had access to the drive. Hmm..
