You can get the text of the selected item in any section of the picker using the same function that the pickerView does, from your custom ViewController class:

-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component

using the selected item

[myPickerView selectedRowInComponent:0]

so to set the text of a label in a custom cell using the currently selected value from the 2nd section of myPickerView (a property of your view controller probably)

[cell.label setText:[self pickerView:myPickerView titleForRow:[myPickerView selectedRowInComponent:1] forComponent:1]];

Just change both :1s to :2s, etc for each section

if you've got this error by using the express generator, I've solved it by using

express --view=ejs myapp

instead of

express --view=pug myapp

To make it work I build my directory like this:

Project Public Restrict

So I edited my webconfig for my public folder:

<location path="Project/Public">
    <system.web>
      <authorization>
        <allow users="?"/>
      </authorization>
    </system.web>
  </location>

And for my Restricted folder:

 <location path="Project/Restricted">
    <system.web>
      <authorization>
        <allow users="*"/>
      </authorizatio>
    </system.web>
  </location>

See here for the spec of * and ?:

https://docs.microsoft.com/en-us/iis/configuration/system.webserver/security/authorization/add

I hope I have helped.

In jQuery Mobile:

For disable

$('#someselectElement').selectmenu().selectmenu('disable').selectmenu('refresh', true);
$('#someTextElement').textinput().textinput('disable');

For enable

$('#someselectElement').selectmenu().selectmenu('enable').selectmenu('refresh', true);
$('#someTextElement').textinput('enable');

You can also use this trick: replace

$("#topbar").click(function(){

by

$(document).on("click", "#topbar", function(){

This will bind an event on a not loaded yet object... ;)

You can use this code(Recommended)

 MemoryStream objMS = new MemoryStream();
 DataTable oDT = new DataTable();//Your DataTable which you want to convert
 oDT.WriteXml(objMS);
 objMS.Position = 0;
 XPathDocument result = new XPathDocument(objMS);

This is another way but first ex. is recommended

StringWriter objSW = new StringWriter();
DataTable oDt = new DataTable();//Your DataTable which you want to convert
oDt.WriteXml(objSW);
string result = objSW.ToString();

Another approach is to use ngModelChange:

Template:

<input type="checkbox" ngModel (ngModelChange)="onChecked(obj, $event)" />

Controller:

onChecked(obj: any, isChecked: boolean){
  console.log(obj, isChecked); // {}, true || false
}

I prefer this method because here you get the relevant object and true/false values of a checkbox.

First, make sure you have Tkinter module installed.

sudo apt-get install python-tk

In python 2 the package name is Tkinter not tkinter.

from Tkinter import *

As the other answers have described, lit and typedLit are how to add constant columns to DataFrames. lit is an important Spark function that you will use frequently, but not for adding constant columns to DataFrames.

You'll commonly be using lit to create org.apache.spark.sql.Column objects because that's the column type required by most of the org.apache.spark.sql.functions.

Suppose you have a DataFrame with a some_date DateType column and would like to add a column with the days between December 31, 2020 and some_date.

Here's your DataFrame:

+----------+
| some_date|
+----------+
|2020-09-23|
|2020-01-05|
|2020-04-12|
+----------+

Here's how to calculate the days till the year end:

val diff = datediff(lit(Date.valueOf("2020-12-31")), col("some_date"))
df
  .withColumn("days_till_yearend", diff)
  .show()

+----------+-----------------+
| some_date|days_till_yearend|
+----------+-----------------+
|2020-09-23|               99|
|2020-01-05|              361|
|2020-04-12|              263|
+----------+-----------------+

You could also use lit to create a year_end column and compute the days_till_yearend like so:

import java.sql.Date

df
  .withColumn("yearend", lit(Date.valueOf("2020-12-31")))
  .withColumn("days_till_yearend", datediff(col("yearend"), col("some_date")))
  .show()

+----------+----------+-----------------+
| some_date|   yearend|days_till_yearend|
+----------+----------+-----------------+
|2020-09-23|2020-12-31|               99|
|2020-01-05|2020-12-31|              361|
|2020-04-12|2020-12-31|              263|
+----------+----------+-----------------+

Most of the time, you don't need to use lit to append a constant column to a DataFrame. You just need to use lit to convert a Scala type to a org.apache.spark.sql.Column object because that's what's required by the function.

See the datediff function signature:

As you can see, datediff requires two Column arguments.

First, I wouldn't recommend using inline styles. If you must, you should try applying floats to each item:

<img style='float:left; height: 24px; width: 24px; margin-right: 4px;' src='design/like.png'/>
<h4 style='float:left;" class='liketext'>$likes</h4>
<img style='float:left; height: 24px; width: 24px; margin-right: 4px;' src='design/dislike.png'/>
<h4 style='float:left;" class='liketext'>$dislikes</h4>

It might require some tweaking afterwards, and clearing the floats.

You can use org.apache.commons.io.IOUtils.toString(InputStream is, Charset chs) to do that.

e.g.

IOUtils.toString(context.getResources().openRawResource(<your_resource_id>), StandardCharsets.UTF_8)

For adding the correct library:

Add the following to your app/build.gradle file:

dependencies {
    compile 'org.apache.directory.studio:org.apache.commons.io:2.4'
}

• https://stackoverflow.com/a/33820307/1815624

or for the Maven repo see -> this link

For direct jar download see-> https://commons.apache.org/proper/commons-io/download_io.cgi

I think you mean to use map instead of filter:

>>> from string import upper
>>> mylis=['this is test', 'another test']
>>> map(upper, mylis)
['THIS IS TEST', 'ANOTHER TEST']

Even simpler, you could use str.upper instead of importing from string (thanks to @alecxe):

>>> map(str.upper, mylis)
['THIS IS TEST', 'ANOTHER TEST']

In Python 2.x, map constructs a new list by applying a given function to every element in a list. filter constructs a new list by restricting to elements that evaluate to True with a given function.

In Python 3.x, map and filter construct iterators instead of lists, so if you are using Python 3.x and require a list the list comprehension approach would be better suited.

In my case build 1 was installed correctly in my mobile using the signed APK (also from Google Play Store). But when I update the application with build 2 for first time, I had an issue installing it with the signed APK as I got "There was a problem parsing the package".

I tried several methods as specified above. But did not work.

After some time, I rerun the commands

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-key.keystore app-release-unsigned.apk myappkeyalias
zipalign -v 4 app-release-unsigned.apk MyApp.apk

and surprisingly, it worked.

It seems sometimes the APK built might be corrupt. So, Re-running jarsigner and zipalign commands resolved my issue.

If you're ok with using a third party library, check out traex/RippleEffect. It allows you to add a Ripple effect to ANY view with just a few lines of code. You just need to wrap, in your xml layout file, the element you want to have a ripple effect with a com.andexert.library.RippleView container.

As an added bonus it requires Min SDK 9 so you can have design consistency across OS versions.

Here's an example taken from the libraries' GitHub repo:

<com.andexert.library.RippleView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:rv_centered="true">

    <ImageView
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:src="@android:drawable/ic_menu_edit"
        android:background="@android:color/holo_blue_dark"/> 

</com.andexert.library.RippleView>

You can change the ripple colour by adding this attribute the the RippleView element: app:rv_color="@color/my_fancy_ripple_color

Token Based (Security / Authentication)

means that In order for us to prove that we’ve access we first have to receive the token. In a real life scenario, the token could be an access card to building, it could be the key to the lock to your house. In order for you to retrieve a key card for your office or the key to your home, you first need to prove who you are, and that you in fact do have access to that token. It could be something as simple as showing someone your ID or giving them a secret password. So imagine I need to get access to my office. I go down to the security office, I show them my ID, and they give me this token, which lets me into the building. Now I have unrestricted access to do whatever I want inside the building, as long as I have my token with me.

What’s the benefit of token based security?

If we think back on the insecure API, what we had to do in that case was that we had to provide our password for everything that we wanted to do.

Imagine that every time we enter a door in our office, we have to give everyone sitting next to the door our password. Now that would be pretty bad, because that means that anyone inside our office could take our password and impersonate us, and that’s pretty bad. Instead, what we do is that we retrieve the token, of course together with password, but we retrieve that from one person. And then we can use this token wherever we want inside the building. Of course if we lose the token, we have the same problem as if someone else knew our password, but that leads us into things like how do we make sure that if we lose the token, we can revoke the access, and maybe the token shouldn’t live for longer than 24hours, so the next day that we come to the office, we need to show our ID again. But still, there’s just one person that we show the ID to, and that’s the security guard sitting where we retrieve the tokens.

This question, although rather old, needs some benchmarks, as it asks for not the most idiomatic way, or the way that can be written in the fewest number of lines, but the fastest way. And it is silly to answer that question without some actual testing. So I compared four solutions, memset vs. std::fill vs. ZERO of AnT's answer vs a solution I made using AVX intrinsics.

Note that this solution is not generic, it only works on data of 32 or 64 bits. Please comment if this code is doing something incorrect.

#include<immintrin.h>
#define intrin_ZERO(a,n){\
size_t x = 0;\
const size_t inc = 32 / sizeof(*(a));/*size of 256 bit register over size of variable*/\
for (;x < n-inc;x+=inc)\
    _mm256_storeu_ps((float *)((a)+x),_mm256_setzero_ps());\
if(4 == sizeof(*(a))){\
    switch(n-x){\
    case 3:\
        (a)[x] = 0;x++;\
    case 2:\
        _mm_storeu_ps((float *)((a)+x),_mm_setzero_ps());break;\
    case 1:\
        (a)[x] = 0;\
        break;\
    case 0:\
        break;\
    };\
}\
else if(8 == sizeof(*(a))){\
switch(n-x){\
    case 7:\
        (a)[x] = 0;x++;\
    case 6:\
        (a)[x] = 0;x++;\
    case 5:\
        (a)[x] = 0;x++;\
    case 4:\
        _mm_storeu_ps((float *)((a)+x),_mm_setzero_ps());break;\
    case 3:\
        (a)[x] = 0;x++;\
    case 2:\
        ((long long *)(a))[x] = 0;break;\
    case 1:\
        (a)[x] = 0;\
        break;\
    case 0:\
        break;\
};\
}\
}

I will not claim that this is the fastest method, since I am not a low level optimization expert. Rather it is an example of a correct architecture dependent implementation that is faster than memset.

Now, onto the results. I calculated performance for size 100 int and long long arrays, both statically and dynamically allocated, but with the exception of msvc, which did a dead code elimination on static arrays, the results were extremely comparable, so I will show only dynamic array performance. Time markings are ms for 1 million iterations, using time.h's low precision clock function.

clang 3.8 (Using the clang-cl frontend, optimization flags= /OX /arch:AVX /Oi /Ot)

int:
memset:      99
fill:        97
ZERO:        98
intrin_ZERO: 90

long long:
memset:      285
fill:        286
ZERO:        285
intrin_ZERO: 188

gcc 5.1.0 (optimization flags: -O3 -march=native -mtune=native -mavx):

int:
memset:      268
fill:        268
ZERO:        268
intrin_ZERO: 91
long long:
memset:      402
fill:        399
ZERO:        400
intrin_ZERO: 185

msvc 2015 (optimization flags: /OX /arch:AVX /Oi /Ot):

int
memset:      196
fill:        613
ZERO:        221
intrin_ZERO: 95
long long:
memset:      273
fill:        559
ZERO:        376
intrin_ZERO: 188

There is a lot interesting going on here: llvm killing gcc, MSVC's typical spotty optimizations (it does an impressive dead code elimination on static arrays and then has awful performance for fill). Although my implementation is significantly faster, this may only be because it recognizes that bit clearing has much less overhead than any other setting operation.

Clang's implementation merits more looking at, as it is significantly faster. Some additional testing shows that its memset is in fact specialized for zero--non zero memsets for 400 byte array are much slower (~220ms) and are comparable to gcc's. However, the nonzero memsetting with an 800 byte array makes no speed difference, which is probably why in that case, their memset has worse performance than my implementation--the specialization is only for small arrays, and the cuttoff is right around 800 bytes. Also note that gcc 'fill' and 'ZERO' are not optimizing to memset (looking at generated code), gcc is simply generating code with identical performance characteristics.

Conclusion: memset is not really optimized for this task as well as people would pretend it is (otherwise gcc and msvc and llvm's memset would have the same performance). If performance matters then memset should not be a final solution, especially for these awkward medium sized arrays, because it is not specialized for bit clearing, and it is not hand optimized any better than the compiler can do on its own.

I keep this extension method around for this:

public static void Each<T>(this IEnumerable<T> ie, Action<T, int> action)
{
    var i = 0;
    foreach (var e in ie) action(e, i++);
}

And use it like so:

var strings = new List<string>();
strings.Each((str, n) =>
{
    // hooray
});

Or to allow for break-like behaviour:

public static bool Each<T>(this IEnumerable<T> ie, Func<T, int, bool> action)
{
    int i = 0;
    foreach (T e in ie) if (!action(e, i++)) return false;
    return true;
}

var strings = new List<string>() { "a", "b", "c" };

bool iteratedAll = strings.Each ((str, n)) =>
{
    if (str == "b") return false;
    return true;
});

With a readily available Node module, it is possible to get full-length stack traces out of Node (albeit with a minor performance penalty): http://www.mattinsler.com/post/26396305882/announcing-longjohn-long-stack-traces-for-node-js

Your problem is that you didn't set the environment variable.

The error clearly says this:

gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

And in your comment, you say you did this:

set PYTHONPATH=%PYTHONPATH%;C:\My_python_lib

That's nice, but that doesn't set the PYTHON variable, it sets the PYTHONPATH variable.

Meanwhile, just using the set command only affects the current cmd session. If you reboot after that, as you say you did, you end up with a whole new cmd session that doesn't have that variable set in it.

There are a few ways to set environment variables permanently—the easiest is in the System Control Panel in XP, which is of course different in Vista, different again in 7, and different again in 8, but you can google for it.

Alternatively, just do the set right before the npm command, without rebooting in between.

You can test whether you've done things right by doing the exact same thing the config script is trying to do: Before running npm, try running %PYTHON%. If you've done it right, you'll get a Python interpreter (which you can immediately quit). If you get an error, you haven't done it right.

There are two problems with this:

set PYTHON=%PYTHON%;D:\Python

First, you're setting PYTHON to ;D:\Python. That extra semicolon is fine for a semicolon-separated list of paths, like PATH or PYTHONPATH, but not for a single value like PYTHON. And likewise, adding a new value to the existing value is what you want when you want to add another path to a list of paths, but not for a single value. So, you just want set PYTHON=D:\Python.

Second, D:\Python is not the path to your Python interpreter. It's something like D:\Python\Python.exe, or D:\Python\bin\Python.exe. Find the right path, make sure it works on its own (e.g., type D:\Python\bin\Python.exe and make sure you get a Python interpreter), then set the variable and use it.

So:

set PYTHON=D:\Python\bin\Python.exe

Or, if you want to make it permanent, do the equivalent in the Control Panel.

Windows Subsystem for Linux did not exist when this question was asked. It gave these results in my test:

uname -s -> Linux
uname -o -> GNU/Linux
uname -r -> 4.4.0-17763-Microsoft

This means that you need uname -r to distinguish it from native Linux.

As @hanmari mentioned in his comment. when inserting into a postgres tables, the on conflict (..) do nothing is the best code to use for not inserting duplicate data.:

query = "INSERT INTO db_table_name(column_name)
         VALUES(%s) ON CONFLICT (column_name) DO NOTHING;"

The ON CONFLICT line of code will allow the insert statement to still insert rows of data. The query and values code is an example of inserted date from a Excel into a postgres db table. I have constraints added to a postgres table I use to make sure the ID field is unique. Instead of running a delete on rows of data that is the same, I add a line of sql code that renumbers the ID column starting at 1. Example:

q = 'ALTER id_column serial RESTART WITH 1'

If my data has an ID field, I do not use this as the primary ID/serial ID, I create a ID column and I set it to serial. I hope this information is helpful to everyone. *I have no college degree in software development/coding. Everything I know in coding, I study on my own.

The key to debugging situations like these is to run the subquery/inline view on its' own to see what the output is:

  SELECT TOP 1 
         dm.marker_value, 
         dum.profile_id
    FROM DPS_USR_MARKERS dum (NOLOCK)
    JOIN DPS_MARKERS dm (NOLOCK) ON dm.marker_id= dum.marker_id 
                                AND dm.marker_key = 'moneyBackGuaranteeLength'
ORDER BY dm.creation_date

Running that, you would see that the profile_id value didn't match the u.id value of u162231993, which would explain why any mbg references would return null (thanks to the left join; you wouldn't get anything if it were an inner join).

You've coded yourself into a corner using TOP, because now you have to tweak the query if you want to run it for other users. A better approach would be:

   SELECT u.id, 
          x.marker_value 
     FROM DPS_USER u
LEFT JOIN (SELECT dum.profile_id,
                  dm.marker_value,
                  dm.creation_date
             FROM DPS_USR_MARKERS dum (NOLOCK)
             JOIN DPS_MARKERS dm (NOLOCK) ON dm.marker_id= dum.marker_id 
                                         AND dm.marker_key = 'moneyBackGuaranteeLength'
           ) x ON x.profile_id = u.id
     JOIN (SELECT dum.profile_id,
                  MAX(dm.creation_date) 'max_create_date'
             FROM DPS_USR_MARKERS dum (NOLOCK)
             JOIN DPS_MARKERS dm (NOLOCK) ON dm.marker_id= dum.marker_id 
                                         AND dm.marker_key = 'moneyBackGuaranteeLength'
         GROUP BY dum.profile_id) y ON y.profile_id = x.profile_id
                                   AND y.max_create_date = x.creation_date
    WHERE u.id = 'u162231993'

With that, you can change the id value in the where clause to check records for any user in the system.

That data looks like it is in JSON format.

You can use this JSON implementation for Ruby to extract it.

Use the grepl function

grepl( needle, haystack, fixed = TRUE)

like so:

grepl(value, chars, fixed = TRUE)
# TRUE

Use ?grepl to find out more.

LIBRARY_PATH is used by gcc before compilation to search directories containing static and shared libraries that need to be linked to your program.

LD_LIBRARY_PATH is used by your program to search directories containing shared libraries after it has been successfully compiled and linked.

EDIT: As pointed below, your libraries can be static or shared. If it is static then the code is copied over into your program and you don't need to search for the library after your program is compiled and linked. If your library is shared then it needs to be dynamically linked to your program and that's when LD_LIBRARY_PATH comes into play.

MRalwasser, I'd give you a hint, cast the URL.getConnection() to JarURLConnection. Then use JarURLConnection.getJarFile() and voila! You have the JarFile and you are free to access the resources inside.

The rest I leave to you.

Hope this helps!

Well, I think you can assign it to a new object. Something like:

var v = new object();

This worked for me: Open task manager (of your OS) and kill adb.exe process. Now start adb again, now adb should start normally.

mvn eclipse:eclipse -DdownloadSources=true

or

mvn eclipse:eclipse -DdownloadJavadocs=true

or you can add both flags, as Spencer K points out.

Additionally, the =true portion is not required, so you can use

mvn eclipse:eclipse -DdownloadSources -DdownloadJavadocs

There's no way to actively detect if there's a zoom. I found a good entry here on how you can attempt to implement it.

I’ve found two ways of detecting the zoom level. One way to detect zoom level changes relies on the fact that percentage values are not zoomed. A percentage value is relative to the viewport width, and thus unaffected by page zoom. If you insert two elements, one with a position in percentages, and one with the same position in pixels, they’ll move apart when the page is zoomed. Find the ratio between the positions of both elements and you’ve got the zoom level. See test case. http://web.archive.org/web/20080723161031/http://novemberborn.net/javascript/page-zoom-ff3

You could also do it using the tools of the above post. The problem is you're more or less making educated guesses on whether or not the page has zoomed. This will work better in some browsers than other.

There's no way to tell if the page is zoomed if they load your page while zoomed.

1> Add this namspace. using Newtonsoft.Json.Linq;

2> use this source code.

JObject joResponse = JObject.Parse(response);                   
JObject ojObject = (JObject)joResponse["response"];
JArray array= (JArray)ojObject ["chats"];
int id = Convert.ToInt32(array[0].toString());

If you just want to print the raw XML you don't need Simple XML. I added some error handling and a simple example of how you might want to use SimpleXML.

<?php 
$curl = curl_init();        
curl_setopt ($curl, CURLOPT_URL, 'http://rss.news.yahoo.com/rss/topstories');   
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);   
$result = curl_exec ($curl);   

if ($result === false) {
    die('Error fetching data: ' . curl_error($curl));   
}
curl_close ($curl);    

//we can at this point echo the XML if you want
//echo $result;

//parse xml string into SimpleXML objects
$xml = simplexml_load_string($result);

if ($xml === false) {
    die('Error parsing XML');   
}

//now we can loop through the xml structure
foreach ($xml->channel->item as $item) {
    print $item->title;   
}

In IE9+, Chrome or Firefox you can do:

var checkedBoxes = document.querySelectorAll('input[name=mycheckboxes]:checked');

If you want to install opencv 3.4.0, there, unfortunately, is not this version inside conda. You need to use pip instead.

pip install opencv-python==3.4.0.12

This is for format the date?

def format_date(day, month, year):
        # {} betekent 'plaats hier stringvoorstelling van volgend argument'
        return "{}/{}/{}".format(day, month, year)

Yes, indeed you need to have one child inside your <TouchableHighlight>.

And, If you don't want to pollute your file with Views you can use React Fragments to achieve the same.

<TouchableWithoutFeedback>
  <React.Fragment>
   ...
  </React.Fragment>
</TouchableWithoutFeedback>

or even better there is a short syntax for React Fragments. So the above code can be written as below:

<TouchableWithoutFeedback>
  <>
   ...
  </>
</TouchableWithoutFeedback>

If anyone is having issues with their FragmentStatePagerAdapter not properly restoring the state of its fragments...ie...new Fragments are being created by the FragmentStatePagerAdapter instead of it restoring them from state...

Make sure you call ViewPager.setOffscreenPageLimit() BEFORE you call ViewPager.setAdapter(fragmentStatePagerAdapter)

Upon calling ViewPager.setOffscreenPageLimit()...the ViewPager will immediately look to its adapter and try to get its fragments. This could happen before the ViewPager has a chance to restore the Fragments from savedInstanceState(thus creating new Fragments that can't be re-initialized from SavedInstanceState because they're new).

How about calling a function from within your callback instead of returning a value in sync_call()?

function sync_call(input) {
    var value;

    // Assume the async call always succeed
    async_call(input, function(result) {
        value = result;
        use_value(value);
    } );
}

While existing answers definitely solve the purpose, if your'e looking to replicate nested directory structure under two different subdirectories, then you can do this

mkdir -p {main,test}/{resources,scala/com/company}

It will create following directory structure under the directory from where it is invoked

+-- main
¦   +-- resources
¦   +-- scala
¦       +-- com
¦           +-- company
+-- test
    +-- resources
    +-- scala
        +-- com
            +-- company

The example was taken from this link for creating SBT directory structure

The answers presented before mine provide apt solutions to the problem, however, I feel that it is important to understand why this error results:

The Session property of the Page returns an instance of type HttpSessionState relative to that particular request. Page.Session is actually equivalent to calling Page.Context.Session.

MSDN explains how this is possible:

Because ASP.NET pages contain a default reference to the System.Web namespace (which contains the HttpContext class), you can reference the members of HttpContext on an .aspx page without the fully qualified class reference to HttpContext.

However, When you try to access this property within a class in App_Code, the property will not be available to you unless your class derives from the Page Class.

My solution to this oft-encountered scenario is that I never pass page objects to classes. I would rather extract the required objects from the page Session and pass them to the Class in the form of a name-value collection / Array / List, depending on the case.

As an exploration of this topic, I have a presentation titled "Securing TodoMVC Using the Web Cryptography API" (video, code).

It uses the Web Cryptography API to store the todo list encrypted in localStorage by password protecting the application and using a password derived key for encryption. If you forget or lose the password, there is no recovery. (Disclaimer - it was a POC and not intended for production use.)

As the other answers state, this is still susceptible to XSS or malware installed on the client computer. However, any sensitive data would also be in memory when the data is stored on the server and the application is in use. I suggest that offline support may be the compelling use case.

In the end, encrypting localStorage probably only protects the data from attackers that have read only access to the system or its backups. It adds a small amount of defense in depth for OWASP Top 10 item A6-Sensitive Data Exposure, and allows you to answer "Is any of this data stored in clear text long term?" correctly.

When you use setcookie, you can either set the expiration time to 0 or simply omit the parametre - the cookie will then expire at the end of session (ie, when you close the browser).

Use datetime.datetime.strptime:

>>> date.isoweekday()

This might help someone, I had the same issue and found out that i had SD card with drive e:\ After removing my SD card the problem was fixed

Use:

function sortArguments() {
  return arguments.length === 1 ? [arguments[0]] :
                 Array.apply(null, arguments).sort();
}

Array(arg1, arg2, ...) returns [arg1, arg2, ...]

Array(str1) returns [str1]

Array(num1) returns an array that has num1 elements

You must check number of arguments!

Array.slice version (slower):

function sortArguments() {
  return Array.prototype.slice.call(arguments).sort();
}

Array.push version (slower, faster than slice):

function sortArguments() {
  var args = [];
  Array.prototype.push.apply(args, arguments);
  return args.sort();
}

Move version (slower, but small size is faster):

function sortArguments() {
  var args = [];
  for (var i = 0; i < arguments.length; ++i)
    args[i] = arguments[i];
  return args.sort();
}

Array.concat version (slowest):

function sortArguments() {
  return Array.prototype.concat.apply([], arguments).sort();
}

C++20 will have "uniform container erasure", and you'll be able to write:

std::erase_if(numbers, [](int n){ return n % 2 == 0 });

And that will work for vector, set, deque, etc. See cppReference for more info.

Pass re.IGNORECASE to the flags param of search, match, or sub:

re.search('test', 'TeSt', re.IGNORECASE)
re.match('test', 'TeSt', re.IGNORECASE)
re.sub('test', 'xxxx', 'Testing', flags=re.IGNORECASE)

You should check for !test, here is a fiddle showing that.

<span ng-if="!test">null</span>

seeing how the rules are fairly complicated, I'd suggest the following:

/^[a-z](\w*)[a-z0-9]$/i

match the whole string and capture intermediate characters. Then either with the string functions or the following regex:

/__/

check if the captured part has two underscores in a row. For example in Python it would look like this:

>>> import re
>>> def valid(s):
    match = re.match(r'^[a-z](\w*)[a-z0-9]$', s, re.I)
    if match is not None:
        return match.group(1).count('__') == 0
    return False

Use reduce

let arr = [1, 2, 3, 4];_x000D_
_x000D_
let sum = arr.reduce((v, i) => (v + i));_x000D_
_x000D_
console.log(sum);

If you want your code to pick a specific range of digits, be sure to use the && operator instead of the ||.

if (x >= 4 && x <= 9) {_x000D_
  // do something_x000D_
} else {_x000D_
  // do something else_x000D_
}_x000D_
_x000D_
// be sure not to do this_x000D_
_x000D_
if (x >= 4 || x <= 9) {_x000D_
  // do something_x000D_
} else {_x000D_
  // do something else_x000D_
}

As the other answers suggest, editing/removing credentials in the Manage Windows Credentials work and does the job. However, you need to do this each time when the password changes or credentials do not work for some work. Using ssh key has been extremely useful for me where I don't have to bother about these again once I'm done creating a ssh-key and adding them on the server repository (github/bitbucket/gitlab).

Generating a new ssh-key

1. Open Git Bash.

2. Paste the text below, substituting in your repo's email address. $ ssh-keygen -t rsa -b 4096 -C "[email protected]"

3. When you're prompted to "Enter a file in which to save the key," press Enter. This accepts the default file location.

4. Then you'll be asked to type a secure passphrase. You can type a passphrase, hit enter and type the passphrase again.

Or, Hit enter twice for empty passphrase.

5. Copy this on the clipboard:

   clip < ~/.ssh/id_rsa.pub

And then add this key into your repo's profile. For e.g, on github->setting->SSH keys -> paste the key that you coppied ad hit add

Ref: https://help.github.com/en/enterprise/2.15/user/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent#generating-a-new-ssh-key

The Least Popular Answer

1. A deprecated tag is not necessarily a bad tag;
2. There are tags that deal with presentation logic, center is one of them;
3. A center tag is not the same as a div with text-align:center;
4. The fact that you have another way to do something doesn't make it invalid.

Let me explain because there are notorious downvoters here who will think I'm defending oldschool HTML4 or something. No I'm not. But the debate around center is simply a trend war, there is no real reason to ditch a tag that serves a valid purpose well.

So let's see the major arguments against it.

• "It describes presentation, not semantics!"
  No. It describes a logical arrangement - and yes, it has a default appearance, just as other tags like <p> or <ul> do. But the point is the enclosed part's relation to its surroundings. Center says "this is something we separate by visually different positioning".

• "It's not valid"
  Yes it is. It's just deprecated, as in, could be removed later. For 15+ years now. And it's not going anywhere, apparently. There are major sites (including google.com) that use this tag because it's very readable and to the point - and those are the same reasons we like HTML5 tags for.

• "It's not supported in HTML5"
  It's one of the most widely supported tags, actually. MDN says "its use is discouraged since it could be removed at any time" - good point, but that day may never come, to quote a classic. Center was already deprecated in like 2004 or so - it's still here and still useful.

• "It's oldschool"
  Shoelaces are oldschool too. New methods don't invalidate the old. You want to feel progressive and modern: fine. But don't make it the law.

• "It's stupid / awkward / lame / tells a story about you"
  None of these. It's like a hammer: one tool for a specific job. There are other tools for the same job and other jobs for the same tool; but it was created to solve a certain problem and that problem is still around so we might as well just use a dedicated solution.

• "You shouldn't do this, because, CSS"
  Centering can absolutely be achieved by CSS but that's just one way, not the only one, let alone the only appropriate one. Anything that's supported, working and readable should be ok to use. Also, the same argument happened before flexboxes and CSS grids, which is funny because back then there was no CSS way to achieve what center did. No, text-align:center is not the same. No, margin:auto is not the same. Anyone who argued against center tags before flexbox simply didn't know enough about CSS.

TL;DR:

The only reason not to use <center> is because people will hate you.

SQL Server Management Studio

This is your best tool for performing this task. You can generate a script that will build whichever tables you wish from a database as well as insert the data in those tables (as far as I know you have to export all of the data in the selected tables however).

To do this follow these steps:

1. Right-click on your database and select Tasks > Generate Scripts

2. In the Generate and Publish Scripts wizard, select the "Select specific database objects" option

3. Expand the "Tables" tree and select all of the tables you wish to export the scheme and data for, then click Next

4. In the next screen choose how you wish to save the script (the Output Type must remain set as "Save scripts to a specific location"), then click the Advanced button in the top right corner

5. In the newly opened window, under the General section is a setting called "Types of data to script", set this to "Scheme and data" and click OK

6. Click Next, review the export summary and click Next again. This will generate the script to your selected destination.

To restore your database, simply create a new database and change the first line of your generated script to USE [Your.New.Database.Name], then execute. Your new database will now have all of the tables and data you selected from the original database.

Yes, all these are possible when you have the direct access to the servers. But what if you have only access to the server from a web / application server? Well, the situation was this with us a long back and the solution was SQL Server Export to CSV.

The problem with interpreted languages, is that you send the source to get them working (unless you have a compiler to bytecode, but then again, it is quite trivial to decompile).

So, if you don't want to sacrifice performance, you can only act on variable and function names, eg. replacing them with a, b... aa, ab... or a101, a102, etc. And, of course, remove as much space/newlines as you can (that's what so called JS compressors do).
Obfuscating strings will have a performance hit, if you have to encrypt them and decrypt them in real time. Plus a JS debugger can show the final values...

Building on @tmullaney 's answer, you can also left join in the sys.objects view to get insight when explicit permissions have been granted on objects. Make sure to use the LEFT join:

SELECT DISTINCT pr.principal_id, pr.name AS [UserName], pr.type_desc AS [User_or_Role], pr.authentication_type_desc AS [Auth_Type], pe.state_desc,
    pe.permission_name, pe.class_desc, o.[name] AS 'Object' 
    FROM sys.database_principals AS pr 
    JOIN sys.database_permissions AS pe ON pe.grantee_principal_id = pr.principal_id
    LEFT JOIN sys.objects AS o on (o.object_id = pe.major_id)

If it is a reversible migration and the last one which has been executed, then run rake db:rollback. And you can always use version. e.g

the migration file is 20140716084539_create_customer_stats.rb,so the rollback command will be, rake db:migrate:down VERSION=20140716084539

Two things.

1. Remove the parenthesis in setTimeout(startTimer(),startInterval);. Keeping the parentheses invokes the function immediately.

2. Your startTimer function will overwrite the page content with your use of document.write (without the above fix), and wipes out the script and HTML in the process.

That's because your pattern contains a .-^ which is all characters between and including . and ^, which included digits and several other characters as shown below:

If by special characters, you mean punctuation and symbols use:

[\p{P}\p{S}]

which contains all unicode punctuation and symbols.

It tells the compiler that any variable marked by it must be treated in a special way when it is used inside a block. Normally, variables and their contents that are also used in blocks are copied, thus any modification done to these variables don't show outside the block. When they are marked with __block, the modifications done inside the block are also visible outside of it.

For an example and more info, see The __block Storage Type in Apple's Blocks Programming Topics.

The important example is this one:

extern NSInteger CounterGlobal;
static NSInteger CounterStatic;

{
    NSInteger localCounter = 42;
    __block char localCharacter;

    void (^aBlock)(void) = ^(void) {
        ++CounterGlobal;
        ++CounterStatic;
        CounterGlobal = localCounter; // localCounter fixed at block creation
        localCharacter = 'a'; // sets localCharacter in enclosing scope
    };

    ++localCounter; // unseen by the block
    localCharacter = 'b';

    aBlock(); // execute the block
    // localCharacter now 'a'
}

In this example, both localCounter and localCharacter are modified before the block is called. However, inside the block, only the modification to localCharacter would be visible, thanks to the __block keyword. Conversely, the block can modify localCharacter and this modification is visible outside of the block.

There is no difference between them.

If you don't specify a value for any of the half-dozen properties that background is a shorthand for, then it is set to its default value. none and transparent are the defaults.

One explicitly sets the background-image to none and implicitly sets the background-color to transparent. The other is the other way around.

npm install jspdf --save

import jsPDF from 'jspdf';


var doc = new jsPDF()


 doc.fromHTML("<div>JOmin</div>", 1, 1)

If you want to disable particular date(s) in jquery datepicker then here is the simple demo for you.

<script type="text/javascript">
    var arrDisabledDates = {};
    arrDisabledDates[new Date("08/28/2017")] = new Date("08/28/2017");
    arrDisabledDates[new Date("12/23/2017")] = new Date("12/23/2017");
    $(".datepicker").datepicker({
        dateFormat: "dd/mm/yy",
        beforeShowDay: function (date) {
            var day = date.getDay(),
                    bDisable = arrDisabledDates[date];
            if (bDisable)
                return [false, "", ""]
        }
    });
</script>

It depends a bit on your exact requirements. I'm assuming: all numbers, any length, numbers cannot have leading zeros nor contain commas or decimal points. individual numbers always separated by a comma then a space, and the last number does NOT have a comma and space after it. Any of these being wrong would simplify the solution.

([1-9][0-9]*,[ ])*[1-9][0-9]*

Here's how I built that mentally:

[0-9]  any digit.
[1-9][0-9]*  leading non-zero digit followed by any number of digits
[1-9][0-9]*, as above, followed by a comma
[1-9][0-9]*[ ]  as above, followed by a space
([1-9][0-9]*[ ])*  as above, repeated 0 or more times
([1-9][0-9]*[ ])*[1-9][0-9]*  as above, with a final number that doesn't have a comma.

As DanielaWaranie mentioned in her answer - there is a way to specify the type of $item when you iterating over $items in $collectionObject: Add @return MyEntitiesClassName to current() and rest of the Iterator and ArrayAccess-methods which return values.

Boom! No need in /** @var SomeObj[] $collectionObj */ over foreach, and works right with collection object, no need to return collection with specific method described as @return SomeObj[].

I suspect not all IDE support it but it works perfectly fine in PhpStorm, which makes me happier.

Example:

class MyCollection implements Countable, Iterator, ArrayAccess {

    /**
     * @return User
     */
    public function current() {
        return $this->items[$this->cursor];
    }

    //... implement rest of the required `interface` methods and your custom
}

What useful i was going to add posting this answer

In my case current() and rest of interface-methods are implemented in Abstract-collection class and I do not know what kind of entities will eventually be stored in collection.

So here is the trick: Do not specify return type in abstract class, instead use PhpDoc instuction @method in description of specific collection class.

Example:

class User {

    function printLogin() {
        echo $this->login;
    }

}

abstract class MyCollection implements Countable, Iterator, ArrayAccess {

    protected $items = [];

    public function current() {
        return $this->items[$this->cursor];
    }

    //... implement rest of the required `interface` methods and your custom
    //... abstract methods which will be shared among child-classes
}

/**
 * @method User current()
 * ...rest of methods (for ArrayAccess) if needed
 */
class UserCollection extends MyCollection {

    function add(User $user) {
        $this->items[] = $user;
    }

    // User collection specific methods...

}

Now, usage of classes:

$collection = new UserCollection();
$collection->add(new User(1));
$collection->add(new User(2));
$collection->add(new User(3));

foreach ($collection as $user) {
    // IDE should `recognize` method `printLogin()` here!
    $user->printLogin();
}

Once again: I suspect not all IDE support it, but PhpStorm does. Try yours, post in comment the results!

I think you have to options:

1. Build a dynamic SQL using sys.tables and sys.columns to perform the search (example here).

2. Use any program that have this function. An example of this is SQL Workbench (free).

You are very close; currently you compare the row[2] with integer 0, make the comparison with the string "0". When you read the data from a file, it is a string and not an integer, so that is why your integer check fails currently:

row[2]!="0":

Also, you can use the with keyword to make the current code slightly more pythonic so that the lines in your code are reduced and you can omit the .close statements:

import csv
with open('first.csv', 'rb') as inp, open('first_edit.csv', 'wb') as out:
    writer = csv.writer(out)
    for row in csv.reader(inp):
        if row[2] != "0":
            writer.writerow(row)

Note that input is a Python builtin, so I've used another variable name instead.

Edit: The values in your csv file's rows are comma and space separated; In a normal csv, they would be simply comma separated and a check against "0" would work, so you can either use strip(row[2]) != 0, or check against " 0".

The better solution would be to correct the csv format, but in case you want to persist with the current one, the following will work with your given csv file format:

$ cat test.py 
import csv
with open('first.csv', 'rb') as inp, open('first_edit.csv', 'wb') as out:
    writer = csv.writer(out)
    for row in csv.reader(inp):
        if row[2] != " 0":
            writer.writerow(row)
$ cat first.csv 
6.5, 5.4, 0, 320
6.5, 5.4, 1, 320
$ python test.py 
$ cat first_edit.csv 
6.5, 5.4, 1, 320

function startTime() {
    var today = new Date(),
        h = checkTime(((today.getHours() + 11) % 12 + 1)),
        m = checkTime(today.getMinutes()),
        s = checkTime(today.getSeconds());
    document.getElementById('demo').innerHTML = h + ":" + m + ":" + s;
    t = setTimeout(function () {
        startTime()
    }, 500);
}
startTime();

})();

[Update: As of its 4.0 release, Express no longer uses Connect. However, Express is still compatible with middleware written for Connect. My original answer is below.]

I'm glad you asked about this, because it's definitely a common point of confusion for folks looking at Node.js. Here's my best shot at explaining it:

• Node.js itself offers an http module, whose createServer method returns an object that you can use to respond to HTTP requests. That object inherits the http.Server prototype.

• Connect also offers a createServer method, which returns an object that inherits an extended version of http.Server. Connect's extensions are mainly there to make it easy to plug in middleware. That's why Connect describes itself as a "middleware framework," and is often analogized to Ruby's Rack.

• Express does to Connect what Connect does to the http module: It offers a createServer method that extends Connect's Server prototype. So all of the functionality of Connect is there, plus view rendering and a handy DSL for describing routes. Ruby's Sinatra is a good analogy.

• Then there are other frameworks that go even further and extend Express! Zappa, for instance, which integrates support for CoffeeScript, server-side jQuery, and testing.

Here's a concrete example of what's meant by "middleware": Out of the box, none of the above serves static files for you. But just throw in connect.static (a middleware that comes with Connect), configured to point to a directory, and your server will provide access to the files in that directory. Note that Express provides Connect's middlewares also; express.static is the same as connect.static. (Both were known as staticProvider until recently.)

My impression is that most "real" Node.js apps are being developed with Express these days; the features it adds are extremely useful, and all of the lower-level functionality is still there if you want it.

You can add @PrimaryKey(autoGenerate = true) like this:

@Entity
data class Food(
        var foodName: String, 
        var foodDesc: String, 
        var protein: Double, 
        var carbs: Double, 
        var fat: Double
){
    @PrimaryKey(autoGenerate = true)
    var foodId: Int = 0 // or foodId: Int? = null
    var calories: Double = 0.toDouble()
}

Let me add my 2¢, it's my job to get good and clean data for a hedge-fund, I've seen quite a lot of data feeds and historical data providers. This is mainly about US stock data.

To start with, if you have some money don't bother with downloading data from Yahoo, get the end of day data straight from CSI data, this is where Yahoo gets their EOD data as well AFAIK. They have an API where you can extract the data to whatever format you want. I think the yearly subscription for data is a few $100 bucks.

The main problem with downloading data from a free service is that you only get stocks that still exist, this is called Survivorship Bias and can give you wrong results if you look at many stocks, because you'll only include the ones that made it so far and not the ones that were de-listed.

For playing around with some intraday data I'd look into IQFeed, they provide several APIs to extract historical data, although they are mainly an outfit for real-time feeds. But here there are quite a few options, some brokers even provide historical data downloads via their APIs, so just pick your poison.

BUT usually all of this data is not very clean, once you really start back testing you'll see that certain stocks are missing or appear as two different symbols, or stock splits are not properly accounted for, etc. And then you realize that historical dividend data is need as well and so you start running in circles, patching data together from 100 different data sources and so on. So to start with a "discount" data feed will do, but as soon as you run more comprehensive backtests you might run into problems depending on what you do. If you just look at, let's say, the S&P 500 stocks this will not be so much a problem though and a "cheap" intraday feed will do.

What you will not find is free intraday data. I mean you might find some examples, I'm sure there's somewhere 5 years of MSFT tick data floating around but that will not get you very far.

Then, if you need the real stuff (level II order book, all ticks as they have happened at all exchanges) one "affordable", yet excellent option is Nanex. They'll actually ship you a drive with terabytes of data. If I remember right its about $3k-4K per year of data. But trust me, once you understand how hard it is to get good intraday data, you won't think this is very much money at all.

Not to discourage you but to get good data is hard, so hard in fact that many hedge-funds and banks spend hundreds of thousands of dollars a month to get data they can trust. Again, you can start somewhere and then go from there but it's good to see it a bit in context.

Edit: The answer above is from my own experience. This write-up from Caltech about available data feeds will give more insights, and especially recommends QuantQuote.

                </form>

You can submit post form, from bootstrap modal using below javascript/jquery code : call the below function onclick of input submit button

    function form_submit() {
        document.getElementById("paymentitrform").submit();
   }  

Java does not support multiple inheritance because of two reasons:

1. In java, every class is a child of Object class. When it inherits from more than one super class, sub class gets the ambiguity to acquire the property of Object class..
2. In java every class has a constructor, if we write it explicitly or not at all. The first statement is calling super() to invoke the supper class constructor. If the class has more than one super class, it gets confused.

So when one class extends from more than one super class, we get compile time error.

I'm developing an app that needs to look similar in all devices with >= API14 when it comes to actionbar and statusbar customization. I've finally found a solution and since it took a bit of my time I'll share it to save some of yours. We start by using an appcompat-21 dependency.

Transparent Actionbar:

values/styles.xml:

<style name="AppTheme" parent="Theme.AppCompat.Light">
...
</style>

<style name="AppTheme.ActionBar.Transparent" parent="AppTheme">
    <item name="android:windowContentOverlay">@null</item>
    <item name="windowActionBarOverlay">true</item>
    <item name="colorPrimary">@android:color/transparent</item>
</style>

<style name="AppTheme.ActionBar" parent="AppTheme">
    <item name="windowActionBarOverlay">false</item>
    <item name="colorPrimary">@color/default_yellow</item>
</style>

values-v21/styles.xml:

<style name="AppTheme" parent="Theme.AppCompat.Light">
    ...
</style>

<style name="AppTheme.ActionBar.Transparent" parent="AppTheme">
    <item name="colorPrimary">@android:color/transparent</item>
</style>

<style name="AppTheme.ActionBar" parent="AppTheme">
    <item name="colorPrimaryDark">@color/bg_colorPrimaryDark</item>
    <item name="colorPrimary">@color/default_yellow</item>
</style>

Now you can use these themes in your AndroidManifest.xml to specify which activities will have a transparent or colored ActionBar:

    <activity
            android:name=".MyTransparentActionbarActivity"
            android:theme="@style/AppTheme.ActionBar.Transparent"/>

    <activity
            android:name=".MyColoredActionbarActivity"
            android:theme="@style/AppTheme.ActionBar"/>

Note: in API>=21 to get the Actionbar transparent you need to get the Statusbar transparent too, otherwise will not respect your colour styles and will stay light-grey.

Transparent Statusbar (only works with API>=19):
This one it's pretty simple just use the following code:

protected void setStatusBarTranslucent(boolean makeTranslucent) {
        if (makeTranslucent) {
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        } else {
            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        }
    }

But you'll notice a funky result:

This happens because when the Statusbar is transparent the layout will use its height. To prevent this we just need to:

SOLUTION ONE:
Add this line android:fitsSystemWindows="true" in your layout view container of whatever you want to be placed bellow the Actionbar:

    ...
        <LinearLayout
                android:fitsSystemWindows="true"
                android:layout_width="match_parent"
                android:layout_height="match_parent">
            ...
        </LinearLayout>
    ...

SOLUTION TWO:
Add a few lines to our previous method:

protected void setStatusBarTranslucent(boolean makeTranslucent) {
        View v = findViewById(R.id.bellow_actionbar);
        if (v != null) {
            int paddingTop = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT ? MyScreenUtils.getStatusBarHeight(this) : 0;
            TypedValue tv = new TypedValue();
            getTheme().resolveAttribute(android.support.v7.appcompat.R.attr.actionBarSize, tv, true);
            paddingTop += TypedValue.complexToDimensionPixelSize(tv.data, getResources().getDisplayMetrics());
            v.setPadding(0, makeTranslucent ? paddingTop : 0, 0, 0);
        }

        if (makeTranslucent) {
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        } else {
            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        }
    }

Where R.id.bellow_actionbar will be the layout container view id of whatever we want to be placed bellow the Actionbar:

...
    <LinearLayout
            android:id="@+id/bellow_actionbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent">
        ...
    </LinearLayout>
...

So this is it, it think I'm not forgetting something. In this example I didn't use a Toolbar but I think it'll have the same result. This is how I customize my Actionbar:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        View vg = getActionBarView();
        getWindow().requestFeature(vg != null ? Window.FEATURE_ACTION_BAR : Window.FEATURE_NO_TITLE);

        super.onCreate(savedInstanceState);
        setContentView(getContentView());

        if (vg != null) {
            getSupportActionBar().setCustomView(vg, new ActionBar.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
            getSupportActionBar().setDisplayShowCustomEnabled(true);
            getSupportActionBar().setDisplayShowHomeEnabled(false);
            getSupportActionBar().setDisplayShowTitleEnabled(false);
            getSupportActionBar().setDisplayUseLogoEnabled(false);
        }
        setStatusBarTranslucent(true);
    }

Note: this is an abstract class that extends ActionBarActivity
Hope it helps!

The quick "in a nut shell" most obvious answer seems like:

#define N_DECIMAL_POINTS_PRECISION (1000) // n = 3. Three decimal points.

float f = 123.456;
int integerPart = (int)f;
int decimalPart = ((int)(f*N_DECIMAL_POINTS_PRECISION)%N_DECIMAL_POINTS_PRECISION);

You would change how many decimal points you want by changing the N_DECIMAL_POINTS_PRECISION to suit your needs.

From the documentation (MySQL 8) :

      Type | Maximum length
-----------+-------------------------------------
  TINYTEXT |           255 (2 8−1) bytes
      TEXT |        65,535 (216−1) bytes = 64 KiB
MEDIUMTEXT |    16,777,215 (224−1) bytes = 16 MiB
  LONGTEXT | 4,294,967,295 (232−1) bytes =  4 GiB

Note that the number of characters that can be stored in your column will depend on the character encoding.

No need for a StringBuilder:

string path = @"c:\hereIAm.txt";
if (!File.Exists(path)) 
{
    // Create a file to write to.
    using (StreamWriter sw = File.CreateText(path)) 
    {
        sw.WriteLine("Here");
        sw.WriteLine("I");
        sw.WriteLine("am.");
    }    
} 

But of course you can use the StringBuilder to create all lines and write them to the file at once.

sw.Write(stringBuilder.ToString());

StreamWriter.Write Method (String) (.NET Framework 1.1)

Writing Text to a File (.NET Framework 1.1)

This worked great with me

func readjson(fileName: String) -> NSData{

    let path = NSBundle.mainBundle().pathForResource(fileName, ofType: "json")
    let jsonData = NSData(contentsOfMappedFile: path!)

    return jsonData!
}

A simple and cross-platform solution would be to use either the cls command on Windows, or clear on Unix systems. Used with os.system, this makes a nice one-liner:

import os
os.system('cls' if os.name == 'nt' else 'clear')

Mac Mountain Lion has the same password now it uses Oracle.

I had the same problem today, while I was upgrading some VC6 project to VC2012.

In my case, it was because some of the operation in Custom Built Steps failed. In project properties, go to Custom Build Step, you can see there maybe some something in command line edit box. Open a windows prompt and paste the command to it. Run, check if there is something wrong and fix it.

If there is no command line in the project property Custom Built Step, maybe you should check properties of every single file of the project.

If the command line has some macro, replace it with an actual value.

Or you can echo the command in VS output window:

• cd %(somedir)%
• echo %(somedir)%

You won't miss it this way.

There's no operator for such usage in C, but a family of functions:

double pow (double base , double exponent);
float powf (float base  , float exponent);
long double powl (long double base, long double exponent);

Note that the later two are only part of standard C since C99.

If you get a warning like:

"incompatible implicit declaration of built in function 'pow' "

That's because you forgot #include <math.h>.

The XML document:

<Home>
    <Addr>
        <Street>ABC</Street>
        <Number>5</Number>
        <Comment>BLAH BLAH BLAH <br/><br/>ABC</Comment>
    </Addr>
</Home>

The XPath expression:

//*[contains(text(), 'ABC')]

//* matches any descendant element of the root node. That is, any element but the root node.

[...] is a predicate, it filters the node-set. It returns nodes for which ... is true:

A predicate filters a node-set [...] to produce a new node-set. For each node in the node-set to be filtered, the PredicateExpr is evaluated [...]; if PredicateExpr evaluates to true for that node, the node is included in the new node-set; otherwise, it is not included.

contains('haystack', 'needle') returns true if haystack contains needle:

Function: boolean contains(string, string)

The contains function returns true if the first argument string contains the second argument string, and otherwise returns false.

But contains() takes a string as its first parameter. And it's passed nodes. To deal with that every node or node-set passed as the first parameter is converted to a string by the string() function:

An argument is converted to type string as if by calling the string function.

string() function returns string-value of the first node:

A node-set is converted to a string by returning the string-value of the node in the node-set that is first in document order. If the node-set is empty, an empty string is returned.

string-value of an element node:

The string-value of an element node is the concatenation of the string-values of all text node descendants of the element node in document order.

string-value of a text node:

The string-value of a text node is the character data.

So, basically string-value is all text that is contained in a node (concatenation of all descendant text nodes).

text() is a node test that matches any text node:

The node test text() is true for any text node. For example, child::text() will select the text node children of the context node.

Having that said, //*[contains(text(), 'ABC')] matches any element (but the root node), the first text node of which contains ABC. Since text() returns a node-set that contains all child text nodes of the context node (relative to which an expression is evaluated). But contains() takes only the first one. So for the document above the path matches the Street element.

The following expression //*[text()[contains(., 'ABC')]] matches any element (but the root node), that has at least one child text node, that contains ABC. . represents the context node. In this case, it's a child text node of any element but the root node. So for the document above the path matches the Street, and the Comment elements.

Now then, //*[contains(., 'ABC')] matches any element (but the root node) that contains ABC (in the concatenation of the descendant text nodes). For the document above it matches the Home, the Addr, the Street, and the Comment elements. As such, //*[contains(., 'BLAH ABC')] matches the Home, the Addr, and the Comment elements.

For angular 5+ version. Putting version helps as angular makes lot of changes.

ngOnInit() {

 this.myForm = formBuilder.group({
      firstName: 'Thomas',
      lastName: 'Mann'
    })
this.formControlValueChanged() // Note if you are doing an edit/fetching data from an observer this must be called only after your form is properly initialized otherwise you will get error.
}

formControlValueChanged(): void {       
        this.myForm.valueChanges.subscribe(value => {
            console.log('value changed', value)
        })
}

We show up two functions that prints a SINGLE character to binary.

void printbinchar(char character)
{
    char output[9];
    itoa(character, output, 2);
    printf("%s\n", output);
}

printbinchar(10) will write into the console

    1010

itoa is a library function that converts a single integer value to a string with the specified base. For example... itoa(1341, output, 10) will write in output string "1341". And of course itoa(9, output, 2) will write in the output string "1001".

The next function will print into the standard output the full binary representation of a character, that is, it will print all 8 bits, also if the higher bits are zero.

void printbincharpad(char c)
{
    for (int i = 7; i >= 0; --i)
    {
        putchar( (c & (1 << i)) ? '1' : '0' );
    }
    putchar('\n');
}

printbincharpad(10) will write into the console

    00001010

Now i present a function that prints out an entire string (without last null character).

void printstringasbinary(char* s)
{
    // A small 9 characters buffer we use to perform the conversion
    char output[9];

    // Until the first character pointed by s is not a null character
    // that indicates end of string...
    while (*s)
    {
        // Convert the first character of the string to binary using itoa.
        // Characters in c are just 8 bit integers, at least, in noawdays computers.
        itoa(*s, output, 2);

        // print out our string and let's write a new line.
        puts(output);

        // we advance our string by one character,
        // If our original string was "ABC" now we are pointing at "BC".
        ++s;
    }
}

Consider however that itoa don't adds padding zeroes, so printstringasbinary("AB1") will print something like:

1000001
1000010
110001

Simply use

SELECT DATEPART(YEAR, SomeDateColumn)

It will return the portion of a DATETIME type that corresponds to the option you specify. SO DATEPART(YEAR, GETDATE()) would return the current year.

Can pass other time formatters instead of YEAR like

• DAY
• MONTH
• SECOND
• MILLISECOND
• ...etc.

The first parameter to concatenate should itself be a sequence of arrays to concatenate:

numpy.concatenate((a,b)) # Note the extra parentheses.

If you want to take control of /usr/bin/

You will need to reboot your system:

Right after the boot sound, Hold down Command-R to boot into the Recovery System

Click the Utilities menu and select Terminal

Type csrutil disable and press return

Click the ? menu and select Restart

Once you have committed your changes, make sure to re-enable SIP! It does a lot to protect your system. (Same steps as above except type: csrutil enable)

The problem is the 'table-layout:fixed' which create evenly-spaced-fixed-width columns. But disabling this css-property will kill the text-overflow because the table will become as large as possible (and than there is noting to overflow).

I'm sorry but in this case Fred can't have his cake and eat it to.. unless the landlord gives Celldito less space to work with in the first place, Fred cannot use his..

You can use UITableViewRowAction's backgroundColor to set custom image or view. The trick is using UIColor(patternImage:).

Basically the width of UITableViewRowAction area is decided by its title, so you can find a exact length of title(or whitespace) and set the exact size of image with patternImage.

To implement this, I made a UIView's extension method.

func image() -> UIImage {
    UIGraphicsBeginImageContextWithOptions(bounds.size, isOpaque, 0)
    guard let context = UIGraphicsGetCurrentContext() else {
        return UIImage()
    }
    layer.render(in: context)
    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return image!
}

and to make a string with whitespace and exact length,

fileprivate func whitespaceString(font: UIFont = UIFont.systemFont(ofSize: 15), width: CGFloat) -> String {
    let kPadding: CGFloat = 20
    let mutable = NSMutableString(string: "")
    let attribute = [NSFontAttributeName: font]
    while mutable.size(attributes: attribute).width < width - (2 * kPadding) {
        mutable.append(" ")
    }
    return mutable as String
}

and now, you can create UITableViewRowAction.

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
    let whitespace = whitespaceString(width: kCellActionWidth)
    let deleteAction = UITableViewRowAction(style: .`default`, title: whitespace) { (action, indexPath) in
        // do whatever you want
    }

    // create a color from patter image and set the color as a background color of action
    let kActionImageSize: CGFloat = 34
    let view = UIView(frame: CGRect(x: 0, y: 0, width: kCellActionWidth, height: kCellHeight))
    view.backgroundColor = UIColor.white
    let imageView = UIImageView(frame: CGRect(x: (kCellActionWidth - kActionImageSize) / 2,
                                              y: (kCellHeight - kActionImageSize) / 2,
                                              width: 34,
                                              height: 34))
    imageView.image = UIImage(named: "x")
    view.addSubview(imageView)
    let image = view.image()

    deleteAction.backgroundColor = UIColor(patternImage: image)

    return [deleteAction]
}

The result will look like this.

Another way to do this is to import custom font which has the image you want to use as a font and use UIButton.appearance. However this will affect other buttons unless you manually set other button's font.

From iOS 11, it will show this message [TableView] Setting a pattern color as backgroundColor of UITableViewRowAction is no longer supported.. Currently it is still working, but it wouldn't work in the future update.

==========================================

For iOS 11+, you can use:

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
  let deleteAction = UIContextualAction(style: .normal, title: "Delete") { (action, view, completion) in
    // Perform your action here
      completion(true)
  }

  let muteAction = UIContextualAction(style: .normal, title: "Mute") { (action, view, completion) in
    // Perform your action here
    completion(true)
  }

  deleteAction.image = UIImage(named: "icon.png")
  deleteAction.backgroundColor = UIColor.red
  return UISwipeActionsConfiguration(actions: [deleteAction, muteAction])
} 

I didn't understand your question ... what do you mean by "when i set every one of my colour"? try this (edit: "#fffff" in original answer changed to "#ffffff"

  yourView.setBackgroundColor(Color.parseColor("#ffffff"));

select convert(nvarchar(255), 4343)

Should do the trick.

This worked for me:

find ./ -type f -exec sed -i 's/string1/string2/' {} \;

Howerver, this did not: sed -i 's/string1/string2/g' *. Maybe "foo" was not meant to be string1 and "bar" not string2.

From JsonProperty javadoc,

Defines name of the logical property, i.e. JSON object field name to use for the property. If value is empty String (which is the default), will try to use name of the field that is annotated.

It basically means that the object implements the __getitem__() method. In other words, it describes objects that are "containers", meaning they contain other objects. This includes strings, lists, tuples, and dictionaries.

var json = jQuery.parseJSON(s); //If you have jQuery.

Since the comment looks cluttered, please use the parse function after enclosing those square brackets inside the quotes.

var s=['{"Select":"11","PhotoCount":"12"}','{"Select":"21","PhotoCount":"22"}'];

Change the above code to

var s='[{"Select":"11","PhotoCount":"12"},{"Select":"21","PhotoCount":"22"}]';

Eg:

$(document).ready(function() {
    var s= '[{"Select":"11","PhotoCount":"12"},{"Select":"21","PhotoCount":"22"}]';

    s = jQuery.parseJSON(s);

    alert( s[0]["Select"] );
});

And then use the parse function. It'll surely work.

EDIT :Extremely sorry that I gave the wrong function name. it's jQuery.parseJSON

Jquery

The json api

Edit (30 April 2020):

Editing since I got an upvote for this answer. There's a browser native function available instead of JQuery (for nonJQuery users), JSON.parse("<json string here>")

If you have existing password for mysql then write as mentioned below :

Find config(dot)inc file under C:\wamp\apps\phpmyadmin3.5.1 Inside this file find this one line

$cfg['Servers'][$i]['password'] =";

and replace it with

$cfg['Servers'][$i]['password'] = **'your-password'**;

There are different ways to do this. I also had this problem and I searched a lot and then I got a simple way to convert MySQL to SQLite.

Follow these steps:

1. First You Need to Install SQLite DB Browser (very small and fast to view Tables and Data)

2. Open your MySQL File in Notepad or it would be great if you open in Notepad++

3. Remove First extra Lines Contains Information or Queries and Save it.

4. Open SQLite DB Browser, Create Database, then Tables, and Same Types as it is in MySQL Database.

5. In Menu Bar of SQLite DB Browser Select File-> then Import data MySQL File which you saved.

It will easily Convert into SQLite After Warning Dialog.

If error then remove more extra lines if your MySQL file have.

You can also Install MySQL to SQLite Converter Software on trial Basis, but the information I am giving for conversion is life time.

I believe (and I am hardly well-versed in Python) that the main difference is that a tuple is immutable (it can't be changed in place after assignment) and a list is mutable (you can append, change, subtract, etc).

So, I tend to make my tuples things that shouldn't change after assignment and my lists things that can.

To remove tagged images which have not container running, you will have to use a little script:

#!/bin/bash

# remove not running containers
docker rm $(docker ps -f "status=exited" -q)

declare -A used_images

# collect images which has running container
for image in $(docker ps | awk 'NR>1 {print $2;}'); do
    id=$(docker inspect --format="{{.Id}}" $image);
    used_images[$id]=$image;
done

# loop over images, delete those without a container
for id in $(docker images --no-trunc -q); do
    if [ -z ${used_images[$id]} ]; then
        echo "images is NOT in use: $id"
        docker rmi $id
    else
        echo "images is in use:     ${used_images[$id]}"
    fi
done

Have a look at System.currentTimeMillis().

Years after everyone's answer, I too want to present how I did it for my project

                        var cell = (Excel.Range)sheet.Cells[1, j + 1];
                        var column = new DataColumn(headers ? cell.Value : string.Empty);
                        dt.Columns.Add(column);
                    }

                    for (int i = 0; i < rowCount; i++)
                    {
                        var r = dt.NewRow();
                        for (int j = 0; j < ColumnCount; j++)
                        {
                            var cell = (Excel.Range)sheet.Cells[i + 1 + (headers ? 1 : 0), j + 1];
                            r[j] = cell.Value;
                        }
                        dt.Rows.Add(r);
                    }

                }
                dataSet.Tables.Add(dt);
            }
        }
        _xl.Quit();
        return dataSet;

My issue was caused by missing bindings in IIS, in the left tree view "Connections", under Sites, Right click on your site > edit bindings > add > https

Choose 'IIS Express Development Certificate' and set port to 443 Then I added another binding to the webconfig:

<endpoint address="wsHttps" binding="wsHttpBinding" bindingConfiguration="DefaultWsHttpBinding" name="Your.bindingname" contract="Your.contract" />

Also added to serviceBehaviours: <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true" />

And eventually it worked, none of the solutions I checked on stackoverflow for this error was applicable to my specific scenario, so including here in case it helps others

Here is a clean solution with no conversion to string and back, and also it doesn't re-calculate time several times as you reset each component of the time to zero. It also uses % (modulus) rather than divide followed by multiply to avoid the double operation.

It requires no third-party dependencies, and it RESPECTS THE TIMEZONE OF THE Calender object passed in. This function returns the moment in time at 12 AM in the timezone of the date (Calendar) you pass in.

public static Calendar date_only(Calendar datetime) {
    final long LENGTH_OF_DAY = 24*60*60*1000;
    long millis = datetime.getTimeInMillis();
    long offset = datetime.getTimeZone().getOffset(millis);
    millis = millis - ((millis + offset) % LENGTH_OF_DAY);
    datetime.setTimeInMillis(millis);
    return datetime;
}

Another common gotcha is thinking you can ignore the Form DragOver (or DragEnter) events. I typically use the Form's DragOver event to set the AllowedEffect, and then a specific control's DragDrop event to handle the dropped data.

I'm using nnoremap in my .vimrc

To single quote a word:

nnoremap sq :silent! normal mpea'<Esc>bi'<Esc>`pl

To remove quotes (works on double quotes as well):

nnoremap qs :silent! normal mpeld bhd `ph<CR>

Rule to remember: 'sq' = single quote.

If you are using Express > 4.0, you could go for serve-favicon

The thing is that you are using the option -t when running your container.

Could you check if enabling the tty option (see reference) in your docker-compose.yml file the container keeps running?

version: '2'
services:
  ubuntu:
        build: .
        container_name: ubuntu
        volumes:
            - ~/sph/laravel52:/www/laravel
        ports:
          - "80:80"
        tty: true

I had the same problem. I wrote my own function using replace on innerHTML, but it would screw up anchor links and such.

To make it work correctly I used a library to get this done.

The library has an awesome API. After including the script I called it like this:

findAndReplaceDOMText(document.body, {
  find: 'texttofind',
  replace: 'texttoreplace'
  }
);

This is behaviour of floating point arithmetic is by specification. Excerpt from the specification, § 15.17.2. Division Operator /:

Division of a nonzero finite value by a zero results in a signed infinity. The sign is determined by the rule stated above.

Using PuTTY's pscp.exe (which I have in an $env:path directory):

pscp -sftp -pw passwd c:\filedump\* user@host:/Outbox/
mv c:\filedump\* c:\backup\*

"Hash and Range Primary Key" means that a single row in DynamoDB has a unique primary key made up of both the hash and the range key. For example with a hash key of X and range key of Y, your primary key is effectively XY. You can also have multiple range keys for the same hash key but the combination must be unique, like XZ and XA. Let's use their examples for each type of table:

Hash Primary Key – The primary key is made of one attribute, a hash attribute. For example, a ProductCatalog table can have ProductID as its primary key. DynamoDB builds an unordered hash index on this primary key attribute.

This means that every row is keyed off of this value. Every row in DynamoDB will have a required, unique value for this attribute. Unordered hash index means what is says - the data is not ordered and you are not given any guarantees into how the data is stored. You won't be able to make queries on an unordered index such as Get me all rows that have a ProductID greater than X. You write and fetch items based on the hash key. For example, Get me the row from that table that has ProductID X. You are making a query against an unordered index so your gets against it are basically key-value lookups, are very fast, and use very little throughput.

Hash and Range Primary Key – The primary key is made of two attributes. The first attribute is the hash attribute and the second attribute is the range attribute. For example, the forum Thread table can have ForumName and Subject as its primary key, where ForumName is the hash attribute and Subject is the range attribute. DynamoDB builds an unordered hash index on the hash attribute and a sorted range index on the range attribute.

This means that every row's primary key is the combination of the hash and range key. You can make direct gets on single rows if you have both the hash and range key, or you can make a query against the sorted range index. For example, get Get me all rows from the table with Hash key X that have range keys greater than Y, or other queries to that affect. They have better performance and less capacity usage compared to Scans and Queries against fields that are not indexed. From their documentation:

Query results are always sorted by the range key. If the data type of the range key is Number, the results are returned in numeric order; otherwise, the results are returned in order of ASCII character code values. By default, the sort order is ascending. To reverse the order, set the ScanIndexForward parameter to false

I probably missed some things as I typed this out and I only scratched the surface. There are a lot more aspects to take into consideration when working with DynamoDB tables (throughput, consistency, capacity, other indices, key distribution, etc.). You should take a look at the sample tables and data page for examples.

You can make your app as device/profile owner and call setScreenCaptureDisabled(). From the docs, this api does the following:

public void setScreenCaptureDisabled (ComponentName admin, boolean disabled) Added in API level 21

Called by a device/profile owner to set whether the screen capture is disabled. Disabling screen capture also prevents the content from being shown on display devices that do not have a secure video output. See FLAG_SECURE for more details about secure surfaces and secure displays.

The calling device admin must be a device or profile owner. If it is not, a security exception will be thrown. Parameters admin Which DeviceAdminReceiver this request is associated with. disabled Whether screen capture is disabled or not.

Alternatively you can become an MDM(Mobile Device Management) partner app.OEMs provides additional APIs to their MDM partner apps to control the device.For example samsung provides api to control screen recording on the device to their MDM partners.

Currently this is the only way you can enforce screen capture restrictions.

Pythonic way to do this is ...

np.divide(data.T,vector).T

This takes care of reshaping and also the results are in floating point format. In other answers results are in rounded integer format.

#NOTE: No of columns in both data and vector should match

I would approach it like this:

sizes = [100, 250] print "How much space should the random song list occupy?" print '\n'.join("{0}. {1}Mb".format(n, s)                 for n, s in enumerate(sizes, 1)) # present choices choice = int(raw_input("Enter choice:")) # throws error if not int size = sizes[0] # safe starting choice if choice in range(2, len(sizes) + 1):     size = sizes[choice - 1] # note index offset from choice print "You  want to create a random song list that is {0}Mb.".format(size) 

You could also loop until you get an acceptable answer and cover yourself in case of error:

choice = 0 while choice not in range(1, len(sizes) + 1): # loop     try: # guard against error         choice = int(raw_input(...))     except ValueError: # couldn't make an int         print "Please enter a number"         choice = 0 size = sizes[choice - 1] # now definitely valid 

Here is my answer:

    def draw_text(text, font_name, size, color, x, y, align="nw"):
        font = pg.font.Font(font_name, size)
        text_surface = font.render(text, True, color)
        text_rect = text_surface.get_rect()
        if align == "nw":
            text_rect.topleft = (x, y)
        if align == "ne":
            text_rect.topright = (x, y)
        if align == "sw":
            text_rect.bottomleft = (x, y)
        if align == "se":
            text_rect.bottomright = (x, y)
        if align == "n":
            text_rect.midtop = (x, y)
        if align == "s":
            text_rect.midbottom = (x, y)
        if align == "e":
            text_rect.midright = (x, y)
        if align == "w":
            text_rect.midleft = (x, y)
        if align == "center":
            text_rect.center = (x, y)
        screen.blit(text_surface, text_rect)

Of course, you'll need to import pygame, a font and a screen, but this is just a def to add on to the rest of the code, and then call "draw_text".

Existing solution

The shortest and probably the fastest solution is:

from math import factorial
print factorial(1000)

Building your own

You can also build your own solution. Generally you have two approaches. The one that suits me best is:

from itertools import imap
def factorial(x):
    return reduce(long.__mul__, imap(long, xrange(1, x + 1)))

print factorial(1000)

(it works also for bigger numbers, when the result becomes long)

The second way of achieving the same is:

def factorial(x):
    result = 1
    for i in xrange(2, x + 1):
        result *= i
    return result

print factorial(1000)

Pretty sure this solves what you're looking for:

HTML:

<table>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
</table>

Javascript (using jQuery):

$(document).ready(function(){
    $('.editbtn').click(function(){
        $(this).html($(this).html() == 'edit' ? 'modify' : 'edit');
    });
});

Edit:

Apparently I should have looked at your sample code first ;)

You need to change (at least) the ID attribute of each element. The ID is the unique identifier for each element on the page, meaning that if you have multiple items with the same ID, you'll get conflicts.

By using classes, you can apply the same logic to multiple elements without any conflicts.

JSFiddle sample

public static string RelativeDate(DateTime theDate)
{
    Dictionary<long, string> thresholds = new Dictionary<long, string>();
    int minute = 60;
    int hour = 60 * minute;
    int day = 24 * hour;
    thresholds.Add(60, "{0} seconds ago");
    thresholds.Add(minute * 2, "a minute ago");
    thresholds.Add(45 * minute, "{0} minutes ago");
    thresholds.Add(120 * minute, "an hour ago");
    thresholds.Add(day, "{0} hours ago");
    thresholds.Add(day * 2, "yesterday");
    thresholds.Add(day * 30, "{0} days ago");
    thresholds.Add(day * 365, "{0} months ago");
    thresholds.Add(long.MaxValue, "{0} years ago");
    long since = (DateTime.Now.Ticks - theDate.Ticks) / 10000000;
    foreach (long threshold in thresholds.Keys) 
    {
        if (since < threshold) 
        {
            TimeSpan t = new TimeSpan((DateTime.Now.Ticks - theDate.Ticks));
            return string.Format(thresholds[threshold], (t.Days > 365 ? t.Days / 365 : (t.Days > 0 ? t.Days : (t.Hours > 0 ? t.Hours : (t.Minutes > 0 ? t.Minutes : (t.Seconds > 0 ? t.Seconds : 0))))).ToString());
        }
    }
    return "";
}

I prefer this version for its conciseness, and ability to add in new tick points. This could be encapsulated with a Latest() extension to Timespan instead of that long 1 liner, but for the sake of brevity in posting, this will do. This fixes the an hour ago, 1 hours ago, by providing an hour until 2 hours have elapsed

For those with spaces in the path, you are going to want something like this: n.b. It expands out to an absolute path, rather than relative, so if your running directory path has spaces in, these count too.

set SOURCE=path\with spaces\to\my.log
FOR /F "usebackq delims=" %%A IN ("%SOURCE%") DO (
    ECHO %%A
)

To explain:

(path\with spaces\to\my.log)

Will not parse, because spaces. If it becomes:

("path\with spaces\to\my.log")

It will be handled as a string rather than a file path.

"usebackq delims=" 

See docs will allow the path to be used as a path (thanks to Stephan).

You can use switch case like this:

$(document).ready(function () {_x000D_
  $("#type").change(function () {_x000D_
     switch($(this).val()) {_x000D_
        case 'item1':_x000D_
            $("#size").html("<option value='test'>item1: test 1</option><option value='test2'>item1: test 2</option>");_x000D_
            break;_x000D_
        case 'item2':_x000D_
            $("#size").html("<option value='test'>item2: test 1</option><option value='test2'>item2: test 2</option>");_x000D_
            break;_x000D_
        case 'item3':_x000D_
            $("#size").html("<option value='test'>item3: test 1</option><option value='test2'>item3: test 2</option>");_x000D_
            break;_x000D_
        default:_x000D_
            $("#size").html("<option value=''>--select one--</option>");_x000D_
     }_x000D_

The Css vertical-align property should help you out here:

np.convolve() takes one dimension array. You need to check the input and convert it into 1D.

You can use the np.ravel(), to convert the array to one dimension.

FlatMap behaves very much like map, the difference is that the function it applies returns an observable itself, so it's perfectly suited to map over asynchronous operations.

In the practical sense, the function Map applies just makes a transformation over the chained response (not returning an Observable); while the function FlatMap applies returns an Observable<T>, that is why FlatMap is recommended if you plan to make an asynchronous call inside the method.

Summary:

• Map returns an object of type T
• FlatMap returns an Observable.

A clear example can be seen here: http://blog.couchbase.com/why-couchbase-chose-rxjava-new-java-sdk .

Couchbase Java 2.X Client uses Rx to provide asynchronous calls in a convenient way. Since it uses Rx, it has the methods map and FlatMap, the explanation in their documentation might be helpful to understand the general concept.

To handle errors, override onError on your susbcriber.

Subscriber<String> mySubscriber = new Subscriber<String>() {
    @Override
    public void onNext(String s) { System.out.println(s); }

    @Override
    public void onCompleted() { }

    @Override
    public void onError(Throwable e) { }
};

It might help to look at this document: http://blog.danlew.net/2014/09/15/grokking-rxjava-part-1/

A good source about how to manage errors with RX can be found at: https://gist.github.com/daschl/db9fcc9d2b932115b679

Usign fs with node.

var fs = require('fs');

try {  
    var data = fs.readFileSync('file.txt', 'utf8');
    console.log(data.toString());    
} catch(e) {
    console.log('Error:', e.stack);
}

1. Add app.set('trust proxy', true)
2. Use req.ip or req.ips in the usual way

The trim() method removes whitespace from both sides of a string.

To remove all the spaces from the string use .replace(/\s/g, "")

 this.maintabinfo = this.inner_view_data.replace(/\s/g, "").toLowerCase();

With Visual Studio Code 1.27.2:

1. When I go to File > Preference > Settings, I get the following tab

   

2. I type rulers in Search settings and I get the following list of settings

   

3. Clicking on the first Edit in settings.json, I can edit the user settings

   

4. Clicking on the pen icon that appears to the left of the setting in Default user settings I can copy it on the user settings and edit it

With Visual Studio Code 1.38.1, the screenshot shown on the third point changes to the following one.

The panel for selecting the default user setting values isn't shown anymore.

Structs can have functions just like classes. The only difference is that they are public by default:

struct A {
    void f() {}
};

Additionally, structs can also have constructors and destructors.

struct A {
    A() : x(5) {}
    ~A() {}

    private: int x;
};

Discord doesn't allow colored text. Though, currently, you have two options to "mimic" colored text.

Option #1 (Markdown code-blocks)

Discord supports Markdown and uses highlight.js to highlight code-blocks. Some programming languages have specific color outputs from highlight.js and can be used to mimic colored output.

To use code-blocks, send a normal message in this format (Which follows Markdown's standard format).

```language
message
```

Languages that currently reproduce nice colors: prolog (red/orange), css (yellow).

Option #2 (Embeds)

Discord now supports Embeds and Webhooks, which can be used to display colored blocks, they also support markdown. For documentation on how to use Embeds, please read your lib's documentation.

(Embed Cheat-sheet)

The syntax is wrong. The typedef should be removed.

The Ruby Style Guide says it better than I could:

Use &&/|| for boolean expressions, and/or for control flow. (Rule of thumb: If you have to use outer parentheses, you are using the wrong operators.)

# boolean expression
if some_condition && some_other_condition
  do_something
end

# control flow
document.saved? or document.save!

Use LINQ OrderByDescending method. It returns IOrderedIEnumerable<int>, which you can convert back to Array if you need so. Generally, List<>s are more functional then Arrays.

array = array.OrderByDescending(c => c).ToArray();

If you are using your own computer, install a software called XAMPP (or WAMPP either works). This is basically a website server that only runs on your computer. Then, once it is installed, go to xampp folder and double click the htdocs folder. Now what you need to do is create an html file (I'm gonna call it runpython.html). (Remember to move the python file to htdocs as well)

Add in this to your html body (and inputs as necessary)

<form action = "file_name.py" method = "POST">
   <input type = "submit" value = "Run the Program!!!">
</form>

Now, in the python file, we are basically going to be printing out HTML code.

#We will need a comment here depending on your server. It is basically telling the server where your python.exe is in order to interpret the language. The server is too lazy to do it itself.

    import cgitb
    import cgi

    cgitb.enable() #This will show any errors on your webpage

    inputs = cgi.FieldStorage() #REMEMBER: We do not have inputs, simply a button to run the program. In order to get inputs, give each one a name and call it by inputs['insert_name']

    print "Content-type: text/html" #We are using HTML, so we need to tell the server

    print #Just do it because it is in the tutorial :P

    print "<title> MyPythonWebpage </title>"

    print "Whatever you would like to print goes here, preferably in between tags to make it look nice"

I set the state as any[] type. and in the constructor set the state to null.

onServiceChange = (e) => {
    const {value} = e.target;
    const index = this.state.services.indexOf(value);
    const services = this.state.services.filter(item => item !== value);
    this.setState(prevState => ({
        services: index === -1 ? prevState.services.push(value) && prevState.services : this.state.services.filter(item => item !== value)
    }))
}

In the input element

this.onServiceChange(e)}/> this.onServiceChange(e)}/> this.onServiceChange(e)}/> this.onServiceChange(e)}/>

I figured it out after some time. Thought it might help y'all :)

For security code, please don't generate your tokens this way: $token = md5(uniqid(rand(), TRUE));

• rand() is predictable
• uniqid() only adds up to 29 bits of entropy
• md5() doesn't add entropy, it just mixes it deterministically

Try this out:

Generating a CSRF Token

PHP 7

session_start();
if (empty($_SESSION['token'])) {
    $_SESSION['token'] = bin2hex(random_bytes(32));
}
$token = $_SESSION['token'];

Sidenote: One of my employer's open source projects is an initiative to backport random_bytes() and random_int() into PHP 5 projects. It's MIT licensed and available on Github and Composer as paragonie/random_compat.

PHP 5.3+ (or with ext-mcrypt)

session_start();
if (empty($_SESSION['token'])) {
    if (function_exists('mcrypt_create_iv')) {
        $_SESSION['token'] = bin2hex(mcrypt_create_iv(32, MCRYPT_DEV_URANDOM));
    } else {
        $_SESSION['token'] = bin2hex(openssl_random_pseudo_bytes(32));
    }
}
$token = $_SESSION['token'];

Verifying the CSRF Token

Don't just use == or even ===, use hash_equals() (PHP 5.6+ only, but available to earlier versions with the hash-compat library).

if (!empty($_POST['token'])) {
    if (hash_equals($_SESSION['token'], $_POST['token'])) {
         // Proceed to process the form data
    } else {
         // Log this as a warning and keep an eye on these attempts
    }
}

Going Further with Per-Form Tokens

You can further restrict tokens to only be available for a particular form by using hash_hmac(). HMAC is a particular keyed hash function that is safe to use, even with weaker hash functions (e.g. MD5). However, I recommend using the SHA-2 family of hash functions instead.

First, generate a second token for use as an HMAC key, then use logic like this to render it:

<input type="hidden" name="token" value="<?php
    echo hash_hmac('sha256', '/my_form.php', $_SESSION['second_token']);
?>" />

And then using a congruent operation when verifying the token:

$calc = hash_hmac('sha256', '/my_form.php', $_SESSION['second_token']);
if (hash_equals($calc, $_POST['token'])) {
    // Continue...
}

The tokens generated for one form cannot be reused in another context without knowing $_SESSION['second_token']. It is important that you use a separate token as an HMAC key than the one you just drop on the page.

Bonus: Hybrid Approach + Twig Integration

Anyone who uses the Twig templating engine can benefit from a simplified dual strategy by adding this filter to their Twig environment:

$twigEnv->addFunction(
    new \Twig_SimpleFunction(
        'form_token',
        function($lock_to = null) {
            if (empty($_SESSION['token'])) {
                $_SESSION['token'] = bin2hex(random_bytes(32));
            }
            if (empty($_SESSION['token2'])) {
                $_SESSION['token2'] = random_bytes(32);
            }
            if (empty($lock_to)) {
                return $_SESSION['token'];
            }
            return hash_hmac('sha256', $lock_to, $_SESSION['token2']);
        }
    )
);

With this Twig function, you can use both the general purpose tokens like so:

<input type="hidden" name="token" value="{{ form_token() }}" />

Or the locked down variant:

<input type="hidden" name="token" value="{{ form_token('/my_form.php') }}" />

Twig is only concerned with template rendering; you still must validate the tokens properly. In my opinion, the Twig strategy offers greater flexibility and simplicity, while maintaining the possibility for maximum security.

Single-Use CSRF Tokens

If you have a security requirement that each CSRF token is allowed to be usable exactly once, the simplest strategy regenerate it after each successful validation. However, doing so will invalidate every previous token which doesn't mix well with people who browse multiple tabs at once.

Paragon Initiative Enterprises maintains an Anti-CSRF library for these corner cases. It works with one-use per-form tokens, exclusively. When enough tokens are stored in the session data (default configuration: 65535), it will cycle out the oldest unredeemed tokens first.

In the VBA editor, go to View, Toolbars, Customise... or right click on the tool bar and select Customise...

Under the Commands tab, select the Edit menu on the left.

Then approximately two thirds of the way down there's two icons, Comment Block and Uncomment Block.

Drag and drop these onto your toolbar and then you have easy access to highlight a block of code, and comment it out and uncomment with the click of a button!

For this particular question, the standard suggestion of java.text.SimpleDateFormat works, but has the unfortunate side effect that SimpleDateFormat is not thread-safe and can be the source of particularly nasty problems since it'll corrupt your output in multi-threaded scenarios, and you won't get any exceptions!

I would strongly recommend looking at Joda for anything like this. Why ? It's a much richer and more intuitive time/date library for Java than the current library (and the basis of the up-and-coming new standard Java date/time library, so you'll be learning a soon-to-be-standard API).

The methods below scales AND rotates the bitmap according to the orientation:

public Bitmap scaleAndRotateImage(String path, int orientation, final int targetWidth, final int targetHeight)
{
    Bitmap bitmap = null;

    try
    {
        // Check the dimensions of the Image
        final BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFile(path, options);

        // Adjust the Width and Height
        int sourceWidth, sourceHeight;
        if (orientation == 90 || orientation == 270)
        {
            sourceWidth = options.outHeight;
            sourceHeight = options.outWidth;
        }
        else
        {
            sourceWidth = options.outWidth;
            sourceHeight = options.outHeight;
        }

        // Calculate the maximum required scaling ratio if required and load the bitmap
        if (sourceWidth > targetWidth || sourceHeight > targetHeight)
        {
            float widthRatio = (float)sourceWidth / (float)targetWidth;
            float heightRatio = (float)sourceHeight / (float)targetHeight;
            float maxRatio = Math.max(widthRatio, heightRatio);
            options.inJustDecodeBounds = false;
            options.inSampleSize = (int)maxRatio;
            bitmap = BitmapFactory.decodeFile(path, options);
        }
        else
        {
            bitmap = BitmapFactory.decodeFile(path);
        }

        // We need to rotate the bitmap (if required)
        int orientationInDegrees = exifToDegrees(orientation);
        if (orientation > 0)
        {
            Matrix matrix = new Matrix();
            if (orientation != 0f)
            {
                matrix.preRotate(orientationInDegrees);
            };

            bitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
        }

        // Re-scale the bitmap if necessary
        sourceWidth = bitmap.getWidth();
        sourceHeight = bitmap.getHeight();

        if (sourceWidth != targetWidth || sourceHeight != targetHeight)
        {
            float widthRatio = (float)sourceWidth / (float)targetWidth;
            float heightRatio = (float)sourceHeight / (float)targetHeight;
            float maxRatio = Math.max(widthRatio, heightRatio);
            sourceWidth = (int)((float)sourceWidth / maxRatio);
            sourceHeight = (int)((float)sourceHeight / maxRatio);
            bitmap = Bitmap.createScaledBitmap(bitmap, sourceWidth, sourceHeight, true);
        }
    }
    catch (Exception e)
    {
        Logger.d("Could not rotate the image");
        Logger.d(e.getMessage());
    }
    return bitmap;
}

Example:

public void getPictureFromDevice(Uri Uri,ImageView imageView)
{
    try
    {
        ExifInterface exifInterface = new ExifInterface(Uri.getPath());
        int orientation = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);

        Bitmap bitmap = scaleAndRotateImage(Uri.getPath(), orientation, imageView.getWidth(), imageView.getHeight());
        imageView.setImageBitmap(bitmap);
    }
    catch (OutOfMemoryError outOfMemoryError)
    {
        Logger.d(outOfMemoryError.getLocalizedMessage());
        Logger.d("Failed to load image from filePath (out of memory)");
        Logger.d(Uri.toString());
    }
    catch (Exception e)
    {
        Logger.d("Failed to load image from filePath");
        Logger.d(Uri.toString());
    }
}

Mac OS Mojave

The accepted answer no longer works. When running the command xcode-select --install it tells you to use "Software Update" to install updates.

In this link is the updated method:

Open a Terminal and then:

cd /Library/Developer/CommandLineTools/Packages/
open macOS_SDK_headers_for_macOS_10.14.pkg

This will open an installation Wizard.

Update 12/2019

After updating to Mojave 10.15.1 it seems that using xcode-select --install works as intended.

<html>
<head>
<script type="text/javascript">
function GetTimeZoneOffset() {
    var d = new Date()
    var gmtOffSet = -d.getTimezoneOffset();
    var gmtHours = Math.floor(gmtOffSet / 60);
    var GMTMin = Math.abs(gmtOffSet % 60);
    var dot = ".";
    var retVal = "" + gmtHours + dot + GMTMin;
    document.getElementById('<%= offSet.ClientID%>').value = retVal;
}

</script>
</head>
<body onload="GetTimeZoneOffset()">
    <asp:HiddenField ID="clientDateTime" runat="server" />
    <asp:HiddenField ID="offSet" runat="server" />
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</body>
</html>

key point to notice here is,body has an attribute onload. Just give it a function name and that function will be called on page load.

Alternatively, you can also call the function on page load event like this

<html>
<head>
<script type="text/javascript">

window.onload = load();

function load() {
    var d = new Date()
    var gmtOffSet = -d.getTimezoneOffset();
    var gmtHours = Math.floor(gmtOffSet / 60);
    var GMTMin = Math.abs(gmtOffSet % 60);
    var dot = ".";
    var retVal = "" + gmtHours + dot + GMTMin;
    document.getElementById('<%= offSet.ClientID%>').value = retVal;
}

</script>
</head>
<body >
    <asp:HiddenField ID="clientDateTime" runat="server" />
    <asp:HiddenField ID="offSet" runat="server" />
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox></body>
</body>
</html>

I had the same problem. Solved this by unsing:

android.net.Uri.encode(urlString, ":/");

It encodes the string but skips ":" and "/".

Don't use grep. Download Silver Searcher or ripgrep. They're both outstanding, and way faster than grep or ack with tons of options.

I think you want something like this. The formatting is off, but it should give the essential information you want.

   import java.util.Scanner;
public class BookstoreCredit 
{

   public static void computeDiscount(String name, double gpa) 
   {
      double credits;
      credits = gpa * 10;
      System.out.println(name + " your GPA is " +
         gpa + " so your credit is $" + credits);
   
   }

   public static void main (String args[]) 
   {
      String studentName;
      double gradeAverage;
      Scanner inputDevice = new Scanner(System.in);
      System.out.println("Enter Student name: ");
      studentName = inputDevice.nextLine();
      System.out.println("Enter student GPA: ");
      gradeAverage = inputDevice.nextDouble();  
      
      computeDiscount(studentName, gradeAverage);
   }
}

If you want this for a Single Class, you can use the PropertyNamingStrategy with the @JsonNaming, something like this:

@JsonNaming(PropertyNamingStrategy.LowerCaseWithUnderscoresStrategy.class)
public static class Request {

    String businessName;
    String businessLegalName;

}

Will serialize to:

{
    "business_name" : "",
    "business_legal_name" : ""
}

Since Jackson 2.7 the LowerCaseWithUnderscoresStrategy in deprecated in favor of SnakeCaseStrategy, so you should use:

@JsonNaming(PropertyNamingStrategy.SnakeCaseStrategy.class)
public static class Request {

    String businessName;
    String businessLegalName;

}

Scripts are raw java embedded in the page code, and if you declare variables in your scripts, then they become local variables embedded in the page.

In contrast, JSTL works entirely with scoped attributes, either at page, request or session scope. You need to rework your scriptlet to fish test out as an attribute:

<c:set var="test" value="test1"/>
<%
  String resp = "abc";
  String test = pageContext.getAttribute("test");
  resp = resp + test;
  pageContext.setAttribute("resp", resp);
%>
<c:out value="${resp}"/>

If you look at the docs for <c:set>, you'll see you can specify scope as page, request or session, and it defaults to page.

Better yet, don't use scriptlets at all: they make the baby jesus cry.

It is because the WEB-INF folder does not exist at the location in the sub directory in the error. You either compile the application to use the WEB-INF folder under public_html OR copy the WEB-INF folder in sub folder as in the error above.

For anyone having this problem with newer versions of Eclipse, head over to Window->Preferences->Java->Editor->Content assist->Advanced and mark Java Proposals and Chain Template Proposals as active.

If you use the -i option you need to provide an extension for your backups.

If you have:

File1.txt
File2.cfg

The command (note the lack of space between -i and '' and the -e to make it work on new versions of Mac and on GNU):

sed -i'.original' -e 's/old_link/new_link/g' *

Create 2 backup files like:

File1.txt.original
File2.cfg.original

There is no portable way to avoid making backup files because it is impossible to find a mix of sed commands that works on all cases:

• sed -i -e ... - does not work on OS X as it creates -e backups
• sed -i'' -e ... - does not work on OS X 10.6 but works on 10.9+
• sed -i '' -e ... - not working on GNU

Note Given that there isn't a sed command working on all platforms, you can try to use another command to achieve the same result.

E.g., perl -i -pe's/old_link/new_link/g' *

You can use .attr() as a part of however you plan to toggle it:

$("button").attr("aria-expanded","true");

I also found one more intuitive way using Array.from:

const range = n => Array.from({length: n}, (value, key) => key)

Now this range function will return all the numbers starting from 0 to n-1

A modified version of the range to support start and end is:

const range = (start, end) => Array.from({length: (end - start)}, (v, k) => k + start);

EDIT As suggested by @marco6, you can put this as a static method if it suits your use case

Array.range = (start, end) => Array.from({length: (end - start)}, (v, k) => k + start);

and use it as

Array.range(3, 9)

You have to convert the type of your return value of the method to the Generic type which you pass to the method during calling.

    public static T values<T>()
    {
        Random random = new Random();
        int number = random.Next(1, 4);
        return (T)Convert.ChangeType(number, typeof(T));
    }

You need pass a type that is type casteable for the value you return through that method.

If you would want to return a value which is not type casteable to the generic type you pass, you might have to alter the code or make sure you pass a type that is casteable for the return value of method. So, this approach is not reccomended.

If you want to use names, try a namedtuple:

from collections import namedtuple

Pair = namedtuple("Pair", ["first", "second"])

pairs = [Pair("a", 1), Pair("b", 2), Pair("c", 3)]

for pair in pairs:
    print("First = {}, second = {}".format(pair.first, pair.second))

Your Delivery class is internal (the default visibility for classes), however the property (and presumably the containing class) are public, so the property is more accessible than the Delivery class. You need to either make Delivery public, or restrict the visibility of the thelivery property.

Just use Control.Invoke Method or Control.BeginInvoke Method.

awk '$3 ~ /snow|snowman/' dummy_file

You can try the below:

function formatAMPM() {
    var date = new Date();
    var currDate = date.getDate();
    var hours = date.getHours();
    var dayName = getDayName(date.getDay());
    var minutes = date.getMinutes();
    var monthName = getMonthName(date.getMonth());
    var year = date.getFullYear();
    var ampm = hours >= 12 ? 'pm' : 'am';
    hours = hours % 12;
    hours = hours ? hours : 12; // the hour '0' should be '12'
    minutes = minutes < 10 ? '0' + minutes : minutes;
    var strTime = dayName + ' ' + monthName + ' ' + currDate + ' ' + year + ' ' + hours + ':' + minutes + ' ' + ampm;
    alert(strTime);
}

function getMonthName(month) {
    var ar = new Array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");
    return ar[month];
}

function getDayName(day) {
    var ar1 = new Array("Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat");
    return ar1[day];
}

EDIT: Refer here for a working demo.

<body>
    <input type="button" value="Increase" id="inc" onclick="incNumber()"/>
    <input type="button" value="Decrease" id="dec" onclick="decNumber()"/>

    <label id="display"></label>

    <script type="text/javascript">

    var i = 0;

    function incNumber() {
        if (i < 10) {
            i++;
        } else if (i = 10) {
            i = 0;
        }
        document.getElementById("display").innerHTML = i;
    }

    function decNumber() {
        if (i > 0) {
            --i;
        } else if (i = 0) {
            i = 10;
        }
        document.getElementById("display").innerHTML = i;
    }
    </script>
</body>

Simply give them the same name:

<input type="radio" name="radAnswer" />

You have to make a custom Object.create() function. One that addresses Crockfords concerns and also calls your init function.

This will work:

var userBPrototype = {
    init: function(nameParam) {
        this.name = nameParam;
    },
    sayHello: function() {
        console.log('Hello '+ this.name);
    }
};


function UserB(name) {
    function F() {};
    F.prototype = userBPrototype;
    var f = new F;
    f.init(name);
    return f;
}

var bob = UserB('bob');
bob.sayHello();

Here UserB is like Object.create, but adjusted for our needs.

If you want, you can also call:

var bob = new UserB('bob');

This is exactly what the OUTPUT clause in SQL Server 2005 onwards is excellent for.

EXAMPLE

CREATE TABLE [dbo].[test_table](
    [LockId] [int] IDENTITY(1,1) NOT NULL,
    [StartTime] [datetime] NULL,
    [EndTime] [datetime] NULL,
PRIMARY KEY CLUSTERED 
(
    [LockId] ASC
) ON [PRIMARY]
) ON [PRIMARY]

INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 07','2009 JUL 07')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 08','2009 JUL 08')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 09','2009 JUL 09')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 10','2009 JUL 10')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 11','2009 JUL 11')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 12','2009 JUL 12')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 13','2009 JUL 13')

UPDATE test_table
    SET StartTime = '2011 JUL 01'
    OUTPUT INSERTED.* -- INSERTED reflect the value after the UPDATE, INSERT, or MERGE statement is completed 
WHERE
    StartTime > '2009 JUL 09'

Results in the following being returned

    LockId StartTime                EndTime
-------------------------------------------------------
4      2011-07-01 00:00:00.000  2009-07-10 00:00:00.000
5      2011-07-01 00:00:00.000  2009-07-11 00:00:00.000
6      2011-07-01 00:00:00.000  2009-07-12 00:00:00.000
7      2011-07-01 00:00:00.000  2009-07-13 00:00:00.000

In your particular case, since you cannot use aggregate functions with OUTPUT, you need to capture the output of INSERTED.* in a table variable or temporary table and count the records. For example,

DECLARE @temp TABLE (
  [LockId] [int],
  [StartTime] [datetime] NULL,
  [EndTime] [datetime] NULL 
)

UPDATE test_table
    SET StartTime = '2011 JUL 01'
    OUTPUT INSERTED.* INTO @temp
WHERE
    StartTime > '2009 JUL 09'


-- now get the count of affected records
SELECT COUNT(*) FROM @temp

You can find it like

SELECT DISTINCT OBJECT_NAME(id) FROM syscomments WHERE [text] LIKE '%User%'

It will list distinct stored procedure names that contain text like 'User' inside stored procedure. More info

The most efficient way to implement a sorted list like you want would be to implement an indexable skiplist as in here: Wikipedia: Indexable skiplist. It would allow to have inserts/removals in O(log(n)) and would allow to have indexed access at the same time. And it would also allow duplicates.

Skiplist is a pretty interesting and, I would say, underrated data structure. Unfortunately there is no indexed skiplist implementation in Java base library, but you can use one of open source implementations or implement it yourself. There are regular Skiplist implementations like ConcurrentSkipListSet and ConcurrentSkipListMap

You can get this error if you define a project as an .exe but intent to create a .lib or a .dll

Because behind the scenes the foreach acquires an enumerator, equivalent to this:

using (IEnumerator<int> enumerator = returnArray.getEnumerator()) {
    while (enumerator.MoveNext()) {
        int i = enumerator.Current;
        // do some more stuff
    }
}

This is simple example by using ternary operator to set selected=selected

<?php $plan = array('1' => 'Green','2'=>'Red' ); ?>
<select class="form-control" title="Choose Plan">
<?php foreach ($plan as $key => $value) { ?>
  <option value="<?php echo $key;?>" <?php echo ($key ==  '2') ? ' selected="selected"' : '';?>><?php echo $value;?></option>
<?php } ?>
</select>

Assuming that by "binary code" you mean just plain old data (sequences of bits, or bytes), and that by "letters" you mean characters, the answer is in two steps. But first, some background.

• A character is just a named symbol, like "LATIN CAPITAL LETTER A" or "GREEK SMALL LETTER PI" or "BLACK CHESS KNIGHT". Do not confuse a character (abstract symbol) with a glyph (a picture of a character).
• A character set is a particular set of characters, each of which is associated with a special number, called its codepoint. To see the codepoint mappings in the Unicode character set, see http://www.unicode.org/Public/UNIDATA/UnicodeData.txt.

Okay now here are the two steps:

1. The data, if it is textual, must be accompanied somehow by a character encoding, something like UTF-8, Latin-1, US-ASCII, etc. Each character encoding scheme specifies in great detail how byte sequences are interpreted as codepoints (and conversely how codepoints are encoded as byte sequences).

2. Once the byte sequences are interpreted as codepoints, you have your characters, because each character has a specific codepoint.

A couple notes:

• In some encodings, certain byte sequences correspond to no codepoints at all, so you can have character decoding errors.
• In some character sets, there are codepoints that are unused, that is, they correspond to no character at all.

In other words, not every byte sequence means something as text.

Agree with Jewes, XmlReader is the better way to go, especially if working with a larger XML document or processing multiple in a loop - no need to parse the entire document if you only need the document root.

Here's a simplified version, using XmlReader and MoveToContent().

http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.movetocontent.aspx

using (XmlReader xmlReader = XmlReader.Create(p_fileName))
{
  if (xmlReader.MoveToContent() == XmlNodeType.Element)
    rootNodeName = xmlReader.Name;
}

In Elasticsearch 5.x the above mentioned approach is deprecated. You can use the _source approach, but but in certain situations it can make sense to store a field. For instance, if you have a document with a title, a date, and a very large content field, you may want to retrieve just the title and the date without having to extract those fields from a large _source field:

In this case, you'd use:

{  
   "size": $INT_NUM_OF_DOCS_TO_RETURN,
   "stored_fields":[  
      "doc.headline",
      "doc.text",
      "doc.timestamp_utc"
   ],
   "query":{  
      "bool":{  
         "must":{  
            "term":{  
               "doc.topic":"news_on_things"
            }
         },
         "filter":{  
            "range":{  
               "doc.timestamp_utc":{  
                  "gte":1451606400000,
                  "lt":1483228800000,
                  "format":"epoch_millis"
               }
            }
         }
      }
   },
   "aggs":{  

   }
}

See the documentation on how to index stored fields. Always happy for an Upvote!

The addLast() needs some optimisation as the while loop inside addLast() has O(n) complexity. Below is my implementation of LinkedList. Run the code with ll.addLastx(i) once and run it with ll.addLast(i) again , you can see their is a lot of difference in processing time of addLastx() with addLast().

Node.java

package in.datastructure.java.LinkedList;

/**
* Created by abhishek.panda on 07/07/17.
*/
public final class Node {
    int data;
    Node next;

    Node (int data){
       this.data = data;
    }
    public String toString(){
      return this.data+"--"+ this.next;
    }
}

LinkedList.java

package in.datastructure.java.LinkedList;
import java.util.ArrayList;
import java.util.Date;

public class LinkedList {

    Node head;
    Node lastx;
    /**
     * @description To append node at end looping all nodes from head
     * @param data
     */
    public void addLast(int data){

        if(head == null){
            head = new Node(data);
            return;
        }
        Node last = head;
        while(last.next != null) {
            last = last.next;
        }
        last.next = new Node(data);
    }


    /**
     * @description This keep track on last node and append to it
     * @param data
     */
    public void addLastx(int data){

        if(head == null){
            head = new Node(data);
            lastx = head;
            return;
        }
        if(lastx.next == null){
            lastx.next = new Node(data);
            lastx = lastx.next;
        }

    }

    public String toString(){
        ArrayList<Integer> arrayList = new ArrayList<Integer>(10);
        Node current = head;
        while(current.next != null) {
            arrayList.add(current.data);
            current = current.next;
        }
        if(current.next == null) {
            arrayList.add(current.data);
        }
        return arrayList.toString();
    }


    public static void main(String[] args) {
        LinkedList ll = new LinkedList();
        /**
         * @description Checking the code optimization of append code
         */
        Date startTime = new Date();
        for (int i = 0 ; i < 100000 ; i++){
            ll.addLastx(i);
        }
        Date endTime = new Date();
        System.out.println("To total processing time : " + (endTime.getTime()-startTime.getTime()));
        System.out.println(ll.toString());
    }

}

With version 2.21.0 of selenium-java.jar you can do this;

driver.findElement(By.id("...")).isDisplayed()

Note that exact reason why your code is frozen is not because you set too high request.recv() buffer size. Here is explained What means buffer size in socket.recv(buffer_size)

This code will work until it'll receive an empty TCP message (if you'd print this empty message, it'd show b''):

while True:    
  data = self.request.recv(1024)
  if not data: break

And note, that there is no way to send empty TCP message. socket.send(b'') simply won't work.

Why? Because empty message is sent only when you type socket.close(), so your script will loop as long as you won't close your connection. As Hans L pointed out here are some good methods to end message.

Using Visual Studio IDE for porting Java to C#:

Currently I am using Visual Studio IDE environment for porting codes from Java to C#. Why? Java has a huge libraries and C# enables the access to the UWP ecosystem.

For supporting editing and debugging as well as examining Java Bytecode (disassembly), you could try:

• Java Language Support FYI: please read the issues to get an overview of the limitations and bugs

For supporting Android (Java/C++) development, you could try:

• Java Language Service for Android and Eclipse Android Project Import FYI: this blog gets NetBeans and Eclipse IDE java developers excited :-)

this fails:

 DECLARE @vPortalUID NVARCHAR(32)
 SET @vPortalUID='2A66057D-F4E5-4E2B-B2F1-38C51A96D385'
 DECLARE @nPortalUID AS UNIQUEIDENTIFIER
 SET @nPortalUID = CAST(@vPortalUID AS uniqueidentifier)
 PRINT @nPortalUID

this works

 DECLARE @vPortalUID NVARCHAR(36)
 SET @vPortalUID='2A66057D-F4E5-4E2B-B2F1-38C51A96D385'
 DECLARE @nPortalUID AS UNIQUEIDENTIFIER
 SET @nPortalUID = CAST(@vPortalUID AS UNIQUEIDENTIFIER)
 PRINT @nPortalUID

the difference is NVARCHAR(36), your input parameter is too small!

Change the Encoding to UTF-8 while parsing .This will remove the special characters

While converting a STD class object to array.Cast the object to array by using array function of php.

Try out with following code snippet.

/*** cast the object ***/    
foreach($stdArray as $key => $value)
{
    $stdArray[$key] = (array) $value;
}   
/*** show the results ***/  
print_r( $stdArray );

When a clearfix is used in a parent container, it automatically wraps around all the child elements.

It is usually used after floating elements to clear the float layout.

When float layout is used, it will horizontally align the child elements. Clearfix clears this behaviour.

Example - Bootstrap Panels

In bootstrap, when the class panel is used, there are 3 child types: panel-header, panel-body, panel-footer. All of which have display:block layout but panel-body has a clearfix pre-applied. panel-body is a main container type whereas panel-header & panel-footer isn't intended to be a container, it is just intended to hold some basic text.

If floating elements are added, the parent container does not get wrapped around those elements because the height of floating elements is not inherited by the parent container.

So for panel-header & panel-footer, clearfix is needed to clear the float layout of elements: Clearfix class gives a visual appearance that the height of the parent container has been increased to accommodate all of its child elements.

 <div class="container">
    <div class="panel panel-default">
        <div class="panel-footer">
            <div class="col-xs-6">
                <input type="button" class="btn btn-primary"   value="Button1">
                <input type="button" class="btn btn-primary"   value="Button2">
                <input type="button" class="btn btn-primary"   value="Button3">
            </div>
        </div>
    </div>

    <div class="panel panel-default">
        <div class="panel-footer">
            <div class="col-xs-6">
                <input type="button" class="btn btn-primary"   value="Button1">
                <input type="button" class="btn btn-primary"   value="Button2">
                <input type="button" class="btn btn-primary"   value="Button3">

If you are using Photoshop go File > Save for web (Command + Option + Shift + S). Make sure the Transparency is unchecked and this should work.

You want set_ticks_position rather than set_label_position:

ax.xaxis.set_ticks_position('top') # the rest is the same

This gives me:

document.evaluate() (DOM Level 3 XPath) is supported in Firefox, Chrome, Safari and Opera - the only major browser missing is MSIE. Nevertheless, jQuery supports basic XPath expressions: http://docs.jquery.com/DOM/Traversing/Selectors#XPath_Selectors (moved into a plugin in the current jQuery version, see https://plugins.jquery.com/xpath/). It simply converts XPath expressions into equivalent CSS selectors however.

There is the JavaScriptSerializer class you can use too. That will let you deserialize the json to a .NET object. There's a generic Deserialize<T>, though you will need the .NET object to have a similar signature as the javascript one. Additionally there is also a DeserializeObject method that just makes a plain object. You can then use reflection to get at the properties you need.

If your controller takes a FormCollection, and you didn't add anything else to the data the json should be in form[0]:

public ActionResult Save(FormCollection forms) {
  string json = forms[0];
  // do your thing here.
}

$M2_HOMEis used sometimes, for example, to install Takari Extensions for Apache Maven

One way to find $M2_HOME value is to search for mvn:

sudo find / -name "mvn" 2>/dev/null

And, probably it will be: /opt/maven/

Puedes agregar una columna con tipo de dato distinto , luego copiar los datos y eliminar la columna anterior

TB.Columns.Add("columna1", GetType(Integer))    
TB.Select("id=id").ToList().ForEach(Sub(row) row("columna1") = row("columna2"))    
TB.Columns.Remove("columna2")

There are several problems here:

1. The newdata argument of predict() needs a predictor variable. You should thus pass it values for Coupon, instead of Total, which is the response variable in your model.

2. The predictor variable needs to be passed in as a named column in a data frame, so that predict() knows what the numbers its been handed represent. (The need for this becomes clear when you consider more complicated models, having more than one predictor variable).

3. For this to work, your original call should pass df in through the data argument, rather than using it directly in your formula. (This way, the name of the column in newdata will be able to match the name on the RHS of the formula).

With those changes incorporated, this will work:

model <- lm(Total ~ Coupon, data=df)
new <- data.frame(Coupon = df$Coupon)
predict(model, newdata = new, interval="confidence")

in my case: i got a new pc and I had to download and install a brand new eclipse. by default the proxy was set to native. I was getting that error at first. I then changed it to active. And still it didn't work. And then i put it back to "native" and it worked.

In Android Studio 3.5.3, the Device File Explorer can be found in View -> Tool Windows.

It can also be opened using the vertical tabs on the right-hand side of the main window.

Use an NSNumberFormatter:

NSNumberFormatter *f = [[NSNumberFormatter alloc] init];
f.numberStyle = NSNumberFormatterDecimalStyle;
NSNumber *myNumber = [f numberFromString:@"42"];

If the string is not a valid number, then myNumber will be nil. If it is a valid number, then you now have all of the NSNumber goodness to figure out what kind of number it actually is.
