Here are some notes: The real alphanumeric string is like "0a0a0a0b0c0d" and not like "000000" or "qwertyuio".

All the answers I read here, returned true in both cases. This is not right.

If I want to check if my "00000" string is alphanumeric, my intuition is unquestionably FALSE.

Why? Simple. I cannot find any letter char. So, is a simple numeric string [0-9].

On the other hand, if I wanted to check my "abcdefg" string, my intuition is still FALSE. I don't see numbers, so it's not alphanumeric. Just alpha [a-zA-Z].

The Michael Martin-Smucker's answer has been illuminating.

However he was aimed at achieving better performance instead of regex. This is true, using a low level way there's a better perfomance. But results it's the same. The strings "0123456789" (only numeric), "qwertyuiop" (only alpha) and "0a1b2c3d4f4g" (alphanumeric) returns TRUE as alphanumeric. Same regex /^[a-z0-9]+$/i way. The reason why the regex does not work is as simple as obvious. The syntax [] indicates or, not and. So, if is it only numeric or if is it only letters, regex returns true.

But, the Michael Martin-Smucker's answer was nevertheless illuminating. For me. It allowed me to think at "low level", to create a real function that unambiguously processes an alphanumeric string. I called it like PHP relative function ctype_alnum (edit 2020-02-18: Where, however, this checks OR and not AND).

Here's the code:

function ctype_alnum(str) {
  var code, i, len;
  var isNumeric = false, isAlpha = false; // I assume that it is all non-alphanumeric

  for (i = 0, len = str.length; i < len; i++) {
    code = str.charCodeAt(i);

    switch (true) {
      case code > 47 && code < 58: // check if 0-9
        isNumeric = true;
        break;

      case (code > 64 && code < 91) || (code > 96 && code < 123): // check if A-Z or a-z
        isAlpha = true;
        break;

      default:
        // not 0-9, not A-Z or a-z
        return false; // stop function with false result, no more checks
    }
  }

  return isNumeric && isAlpha; // return the loop results, if both are true, the string is certainly alphanumeric
}

And here is a demo:

function ctype_alnum(str) {
  var code, i, len;
    var isNumeric = false, isAlpha = false; //I assume that it is all non-alphanumeric

    
loop1:
  for (i = 0, len = str.length; i < len; i++) {
    code = str.charCodeAt(i);
        
        
        switch (true){
            case code > 47 && code < 58: // check if 0-9
                isNumeric = true;
                break;
            case (code > 64 && code < 91) || (code > 96 && code < 123): //check if A-Z or a-z
                isAlpha = true;
                break;
            default: // not 0-9, not A-Z or a-z
                return false; //stop function with false result, no more checks
                
        }

  }
    
  return isNumeric && isAlpha; //return the loop results, if both are true, the string is certainly alphanumeric
};

$("#input").on("keyup", function(){

if ($(this).val().length === 0) {$("#results").html(""); return false};
var isAlphaNumeric = ctype_alnum ($(this).val());
    $("#results").html(
        (isAlphaNumeric) ? 'Yes' : 'No'
        )
        
})

This is an implementation of Michael Martin-Smucker's method in JavaScript.

So it turns out that the crux of the problem is that by default, Postgres starts in "autoCommit" mode, and also it needs/uses cursors to be able to "page" through data (ex: read the first 10K results, then the next, then the next), however cursors can only exist within a transaction. So the default is to read all rows, always, into RAM, and then allow your program to start processing "the first result row, then the second" after it has all arrived, for two reasons, it's not in a transaction (so cursors don't work), and also a fetch size hasn't been set.

So how the psql command line tool achieves batched response (its FETCH_COUNT setting) for queries, is to "wrap" its select queries within a short-term transaction (if a transaction isn't yet open), so that cursors can work. You can do something like that also with JDBC:

  static void readLargeQueryInChunksJdbcWay(Connection conn, String originalQuery, int fetchCount, ConsumerWithException<ResultSet, SQLException> consumer) throws SQLException {
    boolean originalAutoCommit = conn.getAutoCommit();
    if (originalAutoCommit) {
      conn.setAutoCommit(false); // start temp transaction
    }
    try (Statement statement = conn.createStatement()) {
      statement.setFetchSize(fetchCount);
      ResultSet rs = statement.executeQuery(originalQuery);
      while (rs.next()) {
        consumer.accept(rs); // or just do you work here
      }
    } finally {
      if (originalAutoCommit) {
        conn.setAutoCommit(true); // reset it, also ends (commits) temp transaction
      }
    }
  }
  @FunctionalInterface
  public interface ConsumerWithException<T, E extends Exception> {
    void accept(T t) throws E;
  }

This gives the benefit of requiring less RAM, and, in my results, seemed to run overall faster, even if you don't need to save the RAM. Weird. It also gives the benefit that your processing of the first row "starts faster" (since it process it a page at a time).

And here's how to do it the "raw postgres cursor" way, along with full demo code, though in my experiments it seemed the JDBC way, above, was slightly faster for whatever reason.

Another option would be to have autoCommit mode off, everywhere, though you still have to always manually specify a fetchSize for each new Statement (or you can set a default fetch size in the URL string).

An example statement that uses a sub-select :

select * into MyNewTable
from
(
select 
  * 
from 
[SomeOtherTablename]
where 
  EventStartDatetime >= '01/JAN/2018' 
)
) mysourcedata
;

note that the sub query must be given a name .. any name .. e.g. above example gives the subquery a name of mysourcedata. Without this a syntax error is issued in SQL*server 2012.

The database should reply with a message like: (9999 row(s) affected)

I think it comes from this line in your XML file:

<context:component-scan base-package="org.assessme.com.controller." />

Replace it by:

<context:component-scan base-package="org.assessme.com." />

It is because your Autowired service is not scanned by Spring since it is not in the right package.

Using md5deep:

md5deep -r FOLDER | awk '{print $1}' | sort | md5sum

I suggest not to rely on stack elements. If someone use your code within different contexts (python interpreter for instance) your stack will change and break your index ([0][3]).

I suggest you something like that:

class MyClass:

    def __init__(self):
        self.function_name = None

    def _Handler(self, **kwargs):
        print('Calling function {} with parameters {}'.format(self.function_name, kwargs))
        self.function_name = None

    def __getattr__(self, attr):
        self.function_name = attr
        return self._Handler


mc = MyClass()
mc.test(FirstParam='my', SecondParam='test')
mc.foobar(OtherParam='foobar')

Maybe it's the comma in your if condition.

function answers() {
var answer=document.getElementById("mySelect");
 if(answer[answer.selectedIndex].value == "To measure time.") {
  alert("That's correct!"); 
 }
}

You can also write it like this.

function answers(){
 document.getElementById("mySelect").value!="To measure time."||(alert('That's correct!'))
}

If you're using a std::string, call length():

std::string str = "hello";
std::cout << str << ":" << str.length();
// Outputs "hello:5"

If you're using a c-string, call strlen().

const char *str = "hello";
std::cout << str << ":" << strlen(str);
// Outputs "hello:5"

Or, if you happen to like using Pascal-style strings (or f***** strings as Joel Spolsky likes to call them when they have a trailing NULL), just dereference the first character.

const char *str = "\005hello";
std::cout << str + 1 << ":" << *str;
// Outputs "hello:5"

If you're connecting to a named instance and UDP is not available when connecting to it, then you may need to specify the protocol as well.

Example: tcp:192.168.1.21\SQL2K5,1443

Use the .text() function:

var text = $("<p> example ive got a string</P>").text();

Update: As Brilliand points out below, if the input string does not contain any tags and you are unlucky enough, it might be treated as a CSS selector. So this version is more robust:

var text = $("<div/>").html("<p> example ive got a string</P>").text();

If anyone's getting lazy and maybe perhaps doesn't know how to configure shell for all those libraries and -ls, then I created a python script(you have to have python3, most linux users have it.) that allows you to easily compile scripts and run them without worrying much, it just has regular system calls, just arranged neatly, I created it for my self but maybe it'd be useful: Here it is

It depends.

Start with Basic I/O, take a look at Properties, take a look at Preferences API and maybe even Java API for XML Processing and Java Architecture for XML Binding

And if none of those meet your particular needs, you could even look at using some kind of Database

If you don't mention the random_state in the code, then whenever you execute your code a new random value is generated and the train and test datasets would have different values each time.

However, if you use a particular value for random_state(random_state = 1 or any other value) everytime the result will be same,i.e, same values in train and test datasets.

works

$('a[href*=#]').each(function () {
    $(this).attr('href', $(this).attr('href').replace('#', '#_'));
    $(this).on( "click", function() {

        var hashname = $(this).attr('href').replace('#_', '');

        if($(this).attr('href') == "#_") {
            $('html, body').animate({ scrollTop: 0 }, 300);
        }
        else {
            var target = $('a[name="' + hashname + '"], #' + hashname),
                targetOffset = target.offset().top;
            if(targetOffset >= 1) {
                $('html, body').animate({ scrollTop: targetOffset-60 }, 300);

Place the image (cancel icon) with position absolute, adjust top and left properties and call method onclick event which clears the input field.

<div class="form-control">
    <input type="text" id="inputField" />

In css position the span accordingly,

#iconSpan {
 position : absolute;
 top:1%;
 left :14%;
}

            intent.setType("text/plain");
            intent.putExtra(Intent.EXTRA_TEXT, element);

} catch (NameNotFoundException e) {

Deleting my .pdb file for the dll solved this issue for me. I'm guessing it has something to do with the fact that the dll was created using ILMerge.

Reference

Execute the workbench.action.reloadWindow command.

There are some ways to do so:

1. Open the command palette (Ctrl + Shift + P) and execute the command:

   >Reload Window    
   

2. Define a keybinding for the command (for example CTRL+F5) in keybindings.json:

   [
     {
       "key": "ctrl+f5",
       "command": "workbench.action.reloadWindow",
       "when": "editorTextFocus"
     }
   ]
   

All above answers perfectly gives the solution to center the form using Bootstrap 4. However, if someone wants to use out of the box Bootstrap 4 css classes without help of any additional styles and also not wanting to use flex, we can do like this.

I hope this helps someone. Thank you.

That can be done using the limit function, this might not seem new but i have added something.The code should go:

SELECT * FROM table_name LIMIT 100,10;

for the above case assume that you have 110 rows from the table and you want to select the last ten, 100 is the row you want to start to print(if you are to print), and ten shows how many rows you want to pick from the table. For a more precised way you can start by selecting all the rows you want to print out and then you grab the last row id if you have an id column(i recommend you put one) then subtract ten from the last id number and that will be where you want to start, this will make your program to function autonomously and for any number of rows, but if you write the value directly i think you will have to change the code every time data is inserted into your table.I think this helps.Pax et Bonum.

Came across a scenario with remote sorting of data store in EXTJS 4.X where the string is sent to the server as a JSON array (of only 1 object).
Similar approach to what is presented previously for a simple string, just need conversion to JsonArray first prior to JsonObject.

String from client: [{"property":"COLUMN_NAME","direction":"ASC"}]

String jsonIn = "[{\"property\":\"COLUMN_NAME\",\"direction\":\"ASC\"}]";
JsonArray o = (JsonArray)new JsonParser().parse(jsonIn);

String sortColumn = o.get(0).getAsJsonObject().get("property").getAsString());
String sortDirection = o.get(0).getAsJsonObject().get("direction").getAsString());

There's no good reason for 1 to be true and 0 to be false; that's just the way things have always been notated. So from a logical perspective, the function in your API isn't "wrong", per se.

That said, it's normally not advisable to work against the idioms of whatever language or framework you're using without a damn good reason to do so, so whoever wrote this function was probably pretty bone-headed, assuming it's not simply a bug.

You can also do this without a marker file.

The %s format to date is seconds since the epoch. find's -mmin flag takes an argument in minutes, so divide the difference in seconds by 60. And the "-" in front of age means find files whose last modification is less than age.

time=1312603983
now=$(date +'%s')
((age = (now - time) / 60))
find . -type f -mmin -$age

With newer versions of gnu find you can use -newermt, which makes it trivial.

I would like to add (this is a bit long for a comment) that even with a timeout of 3000 my tests would still sometimes (randomly) fail with

Timeout - Async callback was not invoked within the 5000ms timeout specified by jest.setTimeout.

Thanks to Tarun's great answer, I think the shortest way to fix a lot of tests is:

describe('puppeteer tests', () => {
  beforeEach(() => {
    jest.setTimeout(10000);
  });

  test('best jest test fest', async () => {
    // Blah
  });
});

The directions state:

1. Download the appropriate Instant Client packages for your platform. All installations REQUIRE the Basic package.
2. Unzip the packages into a single directory such as "instantclient".
3. Set the library loading path in your environment to the directory in Step 2 ("instantclient"). On many UNIX platforms, LD_LIBRARY_PATH is the appropriate environment variable. On Windows, PATH should be used.
4. Start your application and enjoy.

Suggest extracting/unzipping into a new directory. They've suggested instantclient, but you can name the directory anything you like. Name it C:\OracleInstantClient\ if you choose.

Then in Step 3, open a Windows Command Prompt. Type:

PATH C:\OracleInstantClient; %PATH%`

That's all there is to it!

This code extracts the YouTube video duration using the YouTube API v3 by passing a video ID. It worked for me.

<?php
    function getDuration($videoID){
       $apikey = "YOUR-Youtube-API-KEY"; // Like this AIcvSyBsLA8znZn-i-aPLWFrsPOlWMkEyVaXAcv
       $dur = file_get_contents("https://www.googleapis.com/youtube/v3/videos?part=contentDetails&id=$videoID&key=$apikey");
       $VidDuration =json_decode($dur, true);
       foreach ($VidDuration['items'] as $vidTime)
       {
           $VidDuration= $vidTime['contentDetails']['duration'];
       }
       preg_match_all('/(\d+)/',$VidDuration,$parts);
       return $parts[0][0] . ":" .
              $parts[0][1] . ":".
              $parts[0][2]; // Return 1:11:46 (i.e.) HH:MM:SS
    }

    echo getDuration("zyeubYQxHyY"); // Video ID
?>

You can get your domain's own YouTube API key on https://console.developers.google.com and generate credentials for your own requirement.

Can't add a comment to the solution but that didn't work for me. The solution that worked for me was to use:

var des = (MyClass)Newtonsoft.Json.JsonConvert.DeserializeObject(response, typeof(MyClass)); 
return des.data.Count.ToString();

Bootstrap 4+ has made changes to the utility classes for this. From the documentation:

Added .float-{sm,md,lg,xl}-{left,right,none} classes for responsive floats and removed .pull-left and .pull-right since they’re redundant to .float-left and .float-right.

So use the .float-right (or a size equivalent such as .float-lg-right) instead of .pull-right for your right alignment if you're using a newer Bootstrap version.

Your regexp use ^ and $ so it tries to match the entire string. And if you want only a boolean as the result, use test instead of match.

var format = /[!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]+/;

if(format.test(string)){
  return true;
} else {
  return false;
}

Define the class before you use it:

class Something:
    def out(self):
        print("it works")

s = Something()
s.out()

You need to pass self as the first argument to all instance methods.

In terms of how this is implemented, this changes the method - from OrderBy/ThenBy to OrderByDescending/ThenByDescending. However, you can apply the sort separately to the main query...

var qry = from .... // or just dataList.AsEnumerable()/AsQueryable()

if(sortAscending) {
    qry = qry.OrderBy(x=>x.Property);
} else {
    qry = qry.OrderByDescending(x=>x.Property);
}

Any use? You can create the entire "order" dynamically, but it is more involved...

Another trick (mainly appropriate to LINQ-to-Objects) is to use a multiplier, of -1/1. This is only really useful for numeric data, but is a cheeky way of achieving the same outcome.

Here is another solution to it. As requested.

I want to make a new array of car objects that's grouped by make:

function groupBy() {
  const key = 'make';
  return cars.reduce((acc, x) => ({
    ...acc,
    [x[key]]: (!acc[x[key]]) ? [{
      model: x.model,
      year: x.year
    }] : [...acc[x[key]], {
      model: x.model,
      year: x.year
    }]
  }), {})
}

Output:

console.log('Grouped by make key:',groupBy())

I would like to lay claim to the ONE and only solution posted so far that actually works. :-)

Three classes of problems that have to be dealt with.

1. Non-transitive matching rules for lower and uppercase. The Turkish I problem has been mentioned frequently in other replies. According to comments in Android source for String.regionMatches, the Georgian comparison rules requires additional conversion to lower-case when comparing for case-insensitive equality.

2. Cases where upper- and lower-case forms have a different number of letters. Pretty much all of the solutions posted so far fail, in these cases. Example: German STRASSE vs. Straße have case-insensitive equality, but have different lengths.

3. Binding strengths of accented characters. Locale AND context effect whether accents match or not. In French, the uppercase form of 'é' is 'E', although there is a movement toward using uppercase accents . In Canadian French, the upper-case form of 'é' is 'É', without exception. Users in both countries would expect "e" to match "é" when searching. Whether accented and unaccented characters match is locale-specific. Now consider: does "E" equal "É"? Yes. It does. In French locales, anyway.

I am currently using android.icu.text.StringSearch to correctly implement previous implementations of case-insensitive indexOf operations.

Non-Android users can access the same functionality through the ICU4J package, using the com.ibm.icu.text.StringSearch class.

Be careful to reference classes in the correct icu package (android.icu.text or com.ibm.icu.text) as Android and the JRE both have classes with the same name in other namespaces (e.g. Collator).

    this.collator = (RuleBasedCollator)Collator.getInstance(locale);
    this.collator.setStrength(Collator.PRIMARY);

    ....

    StringSearch search = new StringSearch(
         pattern,
         new StringCharacterIterator(targetText),
         collator);
    int index = search.first();
    if (index != SearchString.DONE)
    {
        // remember that the match length may NOT equal the pattern length.
        length = search.getMatchLength();
        .... 
    }

Test Cases (Locale, pattern, target text, expectedResult):

    testMatch(Locale.US,"AbCde","aBcDe",true);
    testMatch(Locale.US,"éèê","EEE",true);

    testMatch(Locale.GERMAN,"STRASSE","Straße",true);
    testMatch(Locale.FRENCH,"éèê","EEE",true);
    testMatch(Locale.FRENCH,"EEE","éèê",true);
    testMatch(Locale.FRENCH,"éèê","ÉÈÊ",true);

    testMatch(new Locale("tr-TR"),"TITLE","title",true);  // Turkish dotless I/i
    testMatch(new Locale("tr-TR"),"TITLE","title",true);  // Turkish dotted I/i
    testMatch(new Locale("tr-TR"),"TITLE","title",false);  // Dotless-I != dotted i.

PS: As best as I can determine, the PRIMARY binding strength should do the right thing when locale-specific rules differentiate between accented and non-accented characters according to dictionary rules; but I don't which locale to use to test this premise. Donated test cases would be gratefully appreciated.

Following steps shows total information about how to get file, file with extension, file without extension. This technique is very helpful for me. Hope it will be helpful to you too.

  $url = 'https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_120x44dp.png';
        $file = file_get_contents($url); // to get file
        $name = basename($url); // to get file name
        $ext = pathinfo($url, PATHINFO_EXTENSION); // to get extension
        $name2 =pathinfo($url, PATHINFO_FILENAME); //file name without extension

<input type="text" input-disabled="editableInput" />
<button ng-click="editableInput = !editableInput">enable/disable</button>

app.controller("myController", function(){
  $scope.editableInput = false;
});

app.directive("inputDisabled", function(){
  return function(scope, element, attrs){
    scope.$watch(attrs.inputDisabled, function(val){
      if(val)
        element.removeAttr("disabled");
      else
        element.attr("disabled", "disabled");
    });
  }
});

You could use jQuery to add an event listener on the document DOM.

    $(document).on("click", function () {_x000D_
        console.log('clicked');_x000D_
    });

I recently fell in love with fuzzyfinder.vim ... :-)

:FuzzyFinderFile will let you open files by typing partial names or patterns.

So what you need to do is replace th:field with th:name and add th:value, th:value will have the value of the variable you're passing across.

<div class="col-auto">
        <input type="text" th:value="${client.name}" th:name="clientName" 
        class="form control">
</div>

Yes you can start with the Wikipedia article explaining the Big O notation, which in a nutshell is a way of describing the "efficiency" (upper bound of complexity) of different type of algorithms. Or you can look at an earlier answer where this is explained in simple english

I use this one:

from pyspark.sql.functions import col
df.select(['vin',col('timeStamp').alias('Date')]).show()

If you need something from super's __init__ to be done in addition to what is being done in the current class's __init__, you must call it yourself, since that will not happen automatically. But if you don't need anything from super's __init__, no need to call it. Example:

>>> class C(object):
        def __init__(self):
            self.b = 1


>>> class D(C):
        def __init__(self):
            super().__init__() # in Python 2 use super(D, self).__init__()
            self.a = 1


>>> class E(C):
        def __init__(self):
            self.a = 1


>>> d = D()
>>> d.a
1
>>> d.b  # This works because of the call to super's init
1
>>> e = E()
>>> e.a
1
>>> e.b  # This is going to fail since nothing in E initializes b...
Traceback (most recent call last):
  File "<pyshell#70>", line 1, in <module>
    e.b  # This is going to fail since nothing in E initializes b...
AttributeError: 'E' object has no attribute 'b'

__del__ is the same way, (but be wary of relying on __del__ for finalization - consider doing it via the with statement instead).

I rarely use __new__. I do all the initialization in __init__.

Here you go:

user@host:~$ sed 's/^[\t ]*//g' < file-in.txt

Or:

user@host:~$ sed 's/^[\t ]*//g' < file-in.txt > file-out.txt

This post is now nearly 5 years old! Python-2.7 will stop receiving official updates from python.org in 2020. Also, Python-3.7 has been released. Check out Python-Future on how to make your Python-2 code compatible with Python-3. For updating conda, the documentation now recommends using conda update --all in each of your conda environments to update all packages and the Python executable for that version. Also, since they changed their name to Anaconda, I don't know if the Windows registry keys are still the same.

There have been no updates to Python(x,y) since June of 2015, so I think it's safe to assume it has been abandoned.

As @cxw comments below, these answers are for the same bit-versions, and by bit-version I mean 64-bit vs. 32-bit. For example, these answers would apply to updating from 64-bit Python-2.7.10 to 64-bit Python-2.7.11, ie: the same bit-version. While it is possible to install two different bit versions of Python together, it would require some hacking, so I'll save that exercise for the reader. If you don't want to hack, I suggest that if switching bit-versions, remove the other bit-version first.

• Anaconda and MiniConda can be used with an existing Python installation by disabling the options to alter the Windows PATH and Registry. After extraction, create a symlink to conda in your bin or install conda from PyPI. Then create another symlink called conda-activate to activate in the Anaconda/Miniconda root bin folder. Now Anaconda/Miniconda is just like Ruby RVM. Just use conda-activate root to enable Anaconda/Miniconda.
• Portable Python is no longer being developed or maintained.

TL;DR

• Using Anaconda or miniconda, then just execute conda update --all to keep each conda environment updated,
• same major version of official Python (e.g. 2.7.5), just install over old (e.g. 2.7.4),
• different major version of official Python (e.g. 3.3), install side-by-side with old, set paths/associations to point to dominant (e.g. 2.7), shortcut to other (e.g. in BASH $ ln /c/Python33/python.exe python3).

The answer depends:

1. If OP has 2.7.x and wants to install newer version of 2.7.x, then

   • if using MSI installer from the official Python website, just install over old version, installer will issue warning that it will remove and replace the older version; looking in "installed programs" in "control panel" before and after confirms that the old version has been replaced by the new version; newer versions of 2.7.x are backwards compatible so this is completely safe and therefore IMHO multiple versions of 2.7.x should never necessary.
   • if building from source, then you should probably build in a fresh, clean directory, and then point your path to the new build once it passes all tests and you are confident that it has been built successfully, but you may wish to keep the old build around because building from source may occasionally have issues. See my guide for building Python x64 on Windows 7 with SDK 7.0.
   • if installing from a distribution such as Python(x,y), see their website. Python(x,y) has been abandoned. I believe that updates can be handled from within Python(x,y) with their package manager, but updates are also included on their website. I could not find a specific reference so perhaps someone else can speak to this. Similar to ActiveState and probably Enthought, Python (x,y) clearly states it is incompatible with other installations of Python:

     It is recommended to uninstall any other Python distribution before installing Python(x,y)

   • Enthought Canopy uses an MSI and will install either into Program Files\Enthought or home\AppData\Local\Enthought\Canopy\App for all users or per user respectively. Newer installations are updated by using the built in update tool. See their documentation.
   • ActiveState also uses an MSI so newer installations can be installed on top of older ones. See their installation notes.

     Other Python 2.7 Installations On Windows, ActivePython 2.7 cannot coexist with other Python 2.7 installations (for example, a Python 2.7 build from python.org). Uninstall any other Python 2.7 installations before installing ActivePython 2.7.

   • Sage recommends that you install it into a virtual machine, and provides a Oracle VirtualBox image file that can be used for this purpose. Upgrades are handled internally by issuing the sage -upgrade command.

   • Anaconda can be updated by using the conda command:

     conda update --all
     

     Anaconda/Miniconda lets users create environments to manage multiple Python versions including Python-2.6, 2.7, 3.3, 3.4 and 3.5. The root Anaconda/Miniconda installations are currently based on either Python-2.7 or Python-3.5.

     Anaconda will likely disrupt any other Python installations. Installation uses MSI installer. [UPDATE: 2016-05-16] Anaconda and Miniconda now use .exe installers and provide options to disable Windows PATH and Registry alterations.

     Therefore Anaconda/Miniconda can be installed without disrupting existing Python installations depending on how it was installed and the options that were selected during installation. If the .exe installer is used and the options to alter Windows PATH and Registry are not disabled, then any previous Python installations will be disabled, but simply uninstalling the Anaconda/Miniconda installation should restore the original Python installation, except maybe the Windows Registry Python\PythonCore keys.

     Anaconda/Miniconda makes the following registry edits regardless of the installation options: HKCU\Software\Python\ContinuumAnalytics\ with the following keys: Help, InstallPath, Modules and PythonPath - official Python registers these keys too, but under Python\PythonCore. Also uninstallation info is registered for Anaconda\Miniconda. Unless you select the "Register with Windows" option during installation, it doesn't create PythonCore, so integrations like Python Tools for Visual Studio do not automatically see Anaconda/Miniconda. If the option to register Anaconda/Miniconda is enabled, then I think your existing Python Windows Registry keys will be altered and uninstallation will probably not restore them.

   • WinPython updates, I think, can be handled through the WinPython Control Panel.
   • PortablePython is no longer being developed. It had no update method. Possibly updates could be unzipped into a fresh directory and then App\lib\site-packages and App\Scripts could be copied to the new installation, but if this didn't work then reinstalling all packages might have been necessary. Use pip list to see what packages were installed and their versions. Some were installed by PortablePython. Use easy_install pip to install pip if it wasn't installed.

2. If OP has 2.7.x and wants to install a different version, e.g. <=2.6.x or >=3.x.x, then installing different versions side-by-side is fine. You must choose which version of Python (if any) to associate with *.py files and which you want on your path, although you should be able to set up shells with different paths if you use BASH. AFAIK 2.7.x is backwards compatible with 2.6.x, so IMHO side-by-side installs is not necessary, however Python-3.x.x is not backwards compatible, so my recommendation would be to put Python-2.7 on your path and have Python-3 be an optional version by creating a shortcut to its executable called python3 (this is a common setup on Linux). The official Python default install path on Windows is

   • C:\Python33 for 3.3.x (latest 2013-07-29)
   • C:\Python32 for 3.2.x
   • &c.
   • C:\Python27 for 2.7.x (latest 2013-07-29)
   • C:\Python26 for 2.6.x
   • &c.

3. If OP is not updating Python, but merely updating packages, they may wish to look into virtualenv to keep the different versions of packages specific to their development projects separate. Pip is also a great tool to update packages. If packages use binary installers I usually uninstall the old package before installing the new one.

I hope this clears up any confusion.

React Version 0.62.1

In your root project directory

Make sure you have already directory android/app/src/main/assets/, if not create directory, after that create new file and save as index.android.bundle and put your file in like this android/app/src/main/assets/index.android.bundle

After that run this

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/

cd android && ./gradlew assembleDebug

Then you can get apk in app/build/outputs/apk/debug/app-debug.apk

For me, I just did a CTRL+C and YES .
And I restart by

ionic serve 

This works for me.

The probably only way which is marginally faster than

d = [[] for x in xrange(n)]

is

from itertools import repeat
d = [[] for i in repeat(None, n)]

It does not have to create a new int object in every iteration and is about 15 % faster on my machine.

Edit: Using NumPy, you can avoid the Python loop using

d = numpy.empty((n, 0)).tolist()

but this is actually 2.5 times slower than the list comprehension.

simply use this in your imagebutton layout

android:background="@null"

using

 android:background="@android:color/transparent 

or

 btn.setBackgroundColor(Color.TRANSPARENT);

doesn't give perfect transparency

It's an argument passed to your success function:

$.ajax({
  type: "POST",
  url: "somescript.php",
  datatype: "html",
  data: dataString,
  success: function(data) {
    alert(data);
    }
});

The full signature is success(data, textStatus, XMLHttpRequest), but you can use just he first argument if it's a simple string coming back. As always, see the docs for a full explanation :)

You can create a DAO method to do this.

@Dao 
interface MyDao {
    @Query("DELETE FROM myTableName")
    public void nukeTable();
}

I know it's kinda late answer but I just lost about half an hour debugging cause of this, It might save someone some time.

BE MINDFUL, If you use angular.equals() on objects that have property obj.$something (property name starts with $) those properties will get ignored in comparison.

Example:

var obj1 = {
  $key0: "A",
  key1: "value1",
  key2: "value2",
  key3: {a: "aa", b: "bb"}
}

var obj2 = {
  $key0: "B"
  key2: "value2",
  key1: "value1",
  key3: {a: "aa", b: "bb"}
}

angular.equals(obj1, obj2) //<--- would return TRUE (despite it's not true)

A Primary key is a unique key.

Each table must have at most ONE primary key but it can have multiple unique key. A primary key is used to uniquely identify a table row. A primary key cannot be NULL since NULL is not a value.

That's really an informational message.

Likely, you're doing OPTIMIZE on an InnoDB table (table using the InnoDB storage engine, rather than the MyISAM storage engine).

InnoDB doesn't support the OPTIMIZE the way MyISAM does. It does something different. It creates an empty table, and copies all of the rows from the existing table into it, and essentially deletes the old table and renames the new table, and then runs an ANALYZE to gather statistics. That's the closest that InnoDB can get to doing an OPTIMIZE.

The message you are getting is basically MySQL server repeating what the InnoDB storage engine told MySQL server:

Table does not support optimize is the InnoDB storage engine saying...

"I (the InnoDB storage engine) don't do an OPTIMIZE operation like my friend (the MyISAM storage engine) does."

"doing recreate + analyze instead" is the InnoDB storage engine saying...

"I have decided to perform a different set of operations which will achieve an equivalent result."

I tired ListIterator but it didn't help my case, where you have to use the list while adding to it. Here's what works for me:

Use LinkedList.

LinkedList<String> l = new LinkedList<String>();
l.addLast("A");

while(!l.isEmpty()){
    String str = l.removeFirst();
    if(/* Condition for adding new element*/)
        l.addLast("<New Element>");
    else
        System.out.println(str);
}

This could give an exception or run into infinite loops. However, as you have mentioned

I'm pretty sure it won't in my case

checking corner cases in such code is your responsibility.

Posting it from my project.

<select name="parent" id="parent"><option value="0">None</option>
<?php
 $select="select=selected";
 $allparent=mysql_query("select * from tbl_page_content where parent='0'");
 while($parent=mysql_fetch_array($allparent))
   {?>
   <option value="<?= $parent['id']; ?>" <?php if( $pageDetail['parent']==$parent['id'] ) { echo($select); }?>><?= $parent['name']; ?></option>
  <?php 
   }
  ?></select>

I don't think you can its an operator and its suppose to return one or the other. It's not if else statement replacement although it can be use for that on certain case.

My solution is to add the ID field as the LAST field in the table, thus bulk insert ignores it and it gets automatic values. Clean and simple ...

For instance, if inserting into a temp table:

CREATE TABLE #TempTable 
(field1 varchar(max), field2 varchar(max), ... 
ROW_ID int IDENTITY(1,1) NOT NULL)

Note that the ROW_ID field MUST always be specified as LAST field!

The reject actually takes one parameter: that's the exception that occurred in your code that caused the promise to be rejected. So, when you call reject() the exception value is undefined, hence the "undefined" part in the error that you get.

You do not show the code that uses the promise, but I reckon it is something like this:

var promise = doSth();
promise.then(function() { doSthHere(); });

Try adding an empty failure call, like this:

promise.then(function() { doSthHere(); }, function() {});

This will prevent the error to appear.

However, I would consider calling reject only in case of an actual error, and also... having empty exception handlers isn't the best programming practice.

I believe that although javascript is an option here, you have a smoother animation through forcing hardware accelerate with CSS3. You can achieve this by setting the following CSS3 properties on the moving div:

div.hardware-accelarate {
     -webkit-transform: translate3d(0,0,0);
        -moz-transform: translate3d(0,0,0);
         -ms-transform: translate3d(0,0,0);
          -o-transform: translate3d(0,0,0);
             transform: translate3d(0,0,0);
}

I've made a plunkr setup for ya'll to test and tweak...

new allocates an amount of memory needed to store the object/array that you request. In this case n numbers of int.

The pointer will then store the address to this block of memory.

But be careful, this allocated block of memory will not be freed until you tell it so by writing

delete [] array;

You are providing a string representation of a dict to the DataFrame constructor, and not a dict itself. So this is the reason you get that error.

So if you want to use your code, you could do:

df = DataFrame(eval(data))

But better would be to not create the string in the first place, but directly putting it in a dict. Something roughly like:

data = []
for row in result_set:
    data.append({'value': row["tag_expression"], 'key': row["tag_name"]})

But probably even this is not needed, as depending on what is exactly in your result_set you could probably:

• provide this directly to a DataFrame: DataFrame(result_set)
• or use the pandas read_sql_query function to do this for you (see docs on this)

Here are the outputs of isset() and empty() for the 4 possibilities: undeclared, null, false and true.

$a=null;
$b=false;
$c=true;

var_dump(array(isset($z1),isset($a),isset($b),isset($c)),true); //$z1 previously undeclared
var_dump(array(empty($z2),empty($a),empty($b),empty($c)),true); //$z2 previously undeclared

//array(4) { [0]=> bool(false) [1]=> bool(false) [2]=> bool(true) [3]=> bool(true) } 
//array(4) { [0]=> bool(true) [1]=> bool(true) [2]=> bool(true) [3]=> bool(false) } 

You'll notice that all the 'isset' results are opposite of the 'empty' results except for case $b=false. All the values (except null which isn't a value but a non-value) that evaluate to false will return true when tested for by isset and false when tested by 'empty'.

So use isset() when you're concerned about the existence of a variable. And use empty when you're testing for true or false. If the actual type of emptiness matters, use is_null and ===0, ===false, ===''.

You can create a delay using the following example

setInterval(function(){alert("Hello")},3000);

Replace 3000 with # of milliseconds

You can place the content of what you want executed inside the function.

I had the same problem with composer update. But for me it only worked after I cleared the composer cache and after deleting the content of the vendor folder:

rm -rf vendor/*
git gc --prune=now
git pull
composer clear-cache
composer update my/package

You must close the project, hover over the project in the welcome screen, then press the delete button.

Obsolete: This answer is correct only for an older version of Notepad++. Converting between tabs/spaces is now built into Notepad++ and the TextFX plugin is no longer available in the Plugin Manager dialog.

• First set the "replace by spaces" setting in Preferences -> Language Menu/Tab Settings.
• Next, open the document you wish to replace tabs with.
• Highlight all the text (CTRL+A).
• Then select TextFX -> TextFX Edit -> Leading spaces to tabs or tabs to spaces.

Note: Make sure TextFX Characters plugin is installed (Plugins -> Plugin manager -> Show plugin manager, Installed tab). Otherwise, there will be no TextFX menu.

Here's what i thought of:

import string

def match(a,b):
    a,b = a.lower(), b.lower()
    error = 0
    for i in string.ascii_lowercase:
            error += abs(a.count(i) - b.count(i))
    total = len(a) + len(b)
    return (total-error)/total

if __name__ == "__main__":
    print(match("pple inc", "Apple Inc."))

Another reason to use $state.params is for non-URL based state, which (to my mind) is woefully underdocumented and very powerful.

I just discovered this while googling about how to pass state without having to expose it in the URL and answered a question elsewhere on SO.

Basically, it allows this sort of syntax:

<a ui-sref="toState(thingy)" class="list-group-item" ng-repeat="thingy in thingies">{{ thingy.referer }}</a>

You can use lambda function, an example for 1D array:

import numpy as np
a = [np.nan, 2, 3]
map(lambda v:0 if np.isnan(v) == True else v, a)

This will give you the result:

[0, 2, 3]

You can use following code:

$course_description = nl2br($_POST["course_description"]);
$course_description = trim($course_description);

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

vertical-align: bottom;

is what you need for your smaller header :)

Late answer, but hopefully worthwhile: The Poor Man's T-SQL Formatter is an open-source (free) T-SQL formatter with complete T-SQL batch/script support (any DDL, any DML), SSMS Plugin, command-line bulk formatter, and other options.

It's available for immediate/online use at http://poorsql.com, and just today graduated to "version 1.0" (it was in beta version for a few months), having just acquired support for MERGE statements, OUTPUT clauses, and other finicky stuff.

The SSMS Add-in allows you to set your own hotkey (default is Ctrl-K, Ctrl-F, to match Visual Studio), and formats the entire script or just the code you have selected/highlighted, if any. Output formatting is customizable.

In SSMS 2008 it combines nicely with the built-in intelli-sense, effectively providing more-or-less the same base functionality as Red Gate's SQL Prompt (SQL Prompt does, of course, have extra stuff, like snippets, quick object scripting, etc).

Feedback/feature requests are more than welcome, please give it a whirl if you get the chance!

Disclosure: This is probably obvious already but I wrote this library/tool/site, so this answer is also shameless self-promotion :)

You can create an XML file in the drawable folder. Call it, for example, shape.xml

In shape.xml:

    <solid
        android:color="#888888" >

This is what I usually do in my apps. Hope this helps....

It sets result to the (unsigned) value resulting from putting the 8 bits of value in the lowest 8 bits of result.

The reason something like this is necessary is that byte is a signed type in Java. If you just wrote:

int result = value;

then result would end up with the value ff ff ff fe instead of 00 00 00 fe. A further subtlety is that the & is defined to operate only on int values¹, so what happens is:

1. value is promoted to an int (ff ff ff fe).
2. 0xff is an int literal (00 00 00 ff).
3. The & is applied to yield the desired value for result.

(The point is that conversion to int happens before the & operator is applied.)

1_{Well, not quite. The & operator works on long values as well, if either operand is a long. But not on byte. See the Java Language Specification, sections 15.22.1 and 5.6.2.}

In this case, one of the easiest and best approach is to first cast it to list and then use where or select.

result = result.ToList().where(p => date >= p.DOB);

I've made a category from @Abizern answer

@implementation NSString (Extensions)
- (NSDictionary *) json_StringToDictionary {
    NSError *error;
    NSData *objectData = [self dataUsingEncoding:NSUTF8StringEncoding];
    NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData options:NSJSONReadingMutableContainers error:&error];
    return (!json ? nil : json);
}
@end

Use it like this,

NSString *jsonString = @"{\"2\":\"3\"}";
NSLog(@"%@",[jsonString json_StringToDictionary]);

There's no prepackaged "do-while", but the general Python way to implement peculiar looping constructs is through generators and other iterators, e.g.:

import itertools

def dowhile(predicate):
  it = itertools.repeat(None)
  for _ in it:
    yield
    if not predicate(): break

so, for example:

i=7; j=3
for _ in dowhile(lambda: i<j):
  print i, j
  i+=1; j-=1

executes one leg, as desired, even though the predicate's already false at the start.

It's normally better to encapsulate more of the looping logic into your generator (or other iterator) -- for example, if you often have cases where one variable increases, one decreases, and you need a do/while loop comparing them, you could code:

def incandec(i, j, delta=1):
  while True:
    yield i, j
    if j <= i: break
    i+=delta; j-=delta

which you can use like:

for i, j in incandec(i=7, j=3):
  print i, j

It's up to you how much loop-related logic you want to put inside your generator (or other iterator) and how much you want to have outside of it (just like for any other use of a function, class, or other mechanism you can use to refactor code out of your main stream of execution), but, generally speaking, I like to see the generator used in a for loop that has little (ideally none) "loop control logic" (code related to updating state variables for the next loop leg and/or making tests about whether you should be looping again or not).

On my windows installation, I get these results:

>>> import sys
>>> sys.executable
'C:\\Python26\\python.exe'
>>> sys.platform
'win32'
>>>

(You can also look in sys.path for reasonable locations.)

Something like this could be useful:

char str[] = "0x1800785";
int num;

sscanf(str, "%x", &num);
printf("0x%x %i\n", num, num); 

Read man sscanf

di = {}
for x in range(20):
    name = '_id%s' % x
    di[name] = type(name, (object), {})
    setattr(di[name], "attr", "value")

        setPreferredSize(new Dimension(400, 90));
        ((JPanel) getContentPane()).setBorder(new EmptyBorder(13, 13, 13, 13) );
        setLayout(new FlowLayout());
        JButton btn = new JButton("Change");
        btn.setActionCommand("myButton");
        btn.addActionListener(this);
        label = new JLabel("flag");
        field = new JTextField(5);
        add(field);
        add(btn);
        add(label);
        pack();
        setLocationRelativeTo(null);
        setVisible(true);
        setResizable(false);
    }
    public void actionPerformed(ActionEvent e)
    {
        if(e.getActionCommand().equals("myButton"))

This will remove the last comma and any whitespace after it:

str = str.replace(/,\s*$/, "");

It uses a regular expression:

• The / mark the beginning and end of the regular expression

• The , matches the comma

• The \s means whitespace characters (space, tab, etc) and the * means 0 or more

• The $ at the end signifies the end of the string

Just make it simple without third party libraries:

    final String source = "FooBar";
    final String target = "Foo";
    final String replacement = "";
    final String result = Pattern.compile(target, Pattern.LITERAL | Pattern.CASE_INSENSITIVE | Pattern.UNICODE_CASE).matcher(source)
.replaceAll(Matcher.quoteReplacement(replacement));

Not an official name per se, but I've heard vertical ellipsis referred to as "snowman" in SAS community.

Alternative way - use custom NavigationBar class.

class NavigationBar: UINavigationBar {

    var hideBackItem = true
    private let emptyTitle = ""

    override func layoutSubviews() {
        if let `topItem` = topItem,
            topItem.backBarButtonItem?.title != emptyTitle,
            hideBackItem {
            topItem.backBarButtonItem = UIBarButtonItem(title: emptyTitle, style: .plain, target: nil, action: nil)
        }

        super.layoutSubviews()
    }

}

That is, this remove back titles whole project. Just set custom class for UINavigationController.

tail -f logfile | grep org.springframework | cut -c 900-

would remove the first 900 characters

cut uses 900- to show the 900th character to the end of the line

however when I pipe all of this through grep I don't get anything

Yes, it is possible to specify your own credentials without modifying the current code. It requires a small piece of code from your part though.

Create an assembly called SomeAssembly.dll with this class :

namespace SomeNameSpace
{
    public class MyProxy : IWebProxy
    {
        public ICredentials Credentials
        {
            get { return new NetworkCredential("user", "password"); }
            //or get { return new NetworkCredential("user", "password","domain"); }
            set { }
        }

        public Uri GetProxy(Uri destination)
        {
            return new Uri("http://my.proxy:8080");
        }

        public bool IsBypassed(Uri host)
        {
            return false;
        }
    }
}

Add this to your config file :

<defaultProxy enabled="true" useDefaultCredentials="false">
  <module type = "SomeNameSpace.MyProxy, SomeAssembly" />
</defaultProxy>

This "injects" a new proxy in the list, and because there are no default credentials, the WebRequest class will call your code first and request your own credentials. You will need to place the assemble SomeAssembly in the bin directory of your CMS application.

This is a somehow static code, and to get all strings like the user, password and URL, you might either need to implement your own ConfigurationSection, or add some information in the AppSettings, which is far more easier.

Escape the quotes with backslashes:

There are special escape characters that you can use in string literals, and these are denoted with a leading backslash.

If you want to keep the heredoc indented for readability:

$ perl -pe 's/^\s*//' << EOF
     line 1
     line 2
EOF

The built-in method for supporting indented heredoc in Bash only supports leading tabs, not spaces.

Perl can be replaced with awk to save a few characters, but the Perl one is probably easier to remember if you know basic regular expressions.

You need to use the m flag:

multiline; treat beginning and end characters (^ and $) as working over multiple lines (i.e., match the beginning or end of each line (delimited by \n or \r), not only the very beginning or end of the whole input string)

Also put the * in the right place:

"DATE:20091201T220000\r\nSUMMARY:Dad's birthday".match(/^SUMMARY\:(.*)$/gm);

Using a function attribute is also very simple

def f():
    if not hasattr(f, 'value'):
        setattr(f, 'value', singletonvalue)
    return f.value

I ran into the same error.

My problem was that I was trying to run two different pods with the same metadata name.

kind: Pod metadata: name: webapp labels: ...

To find all the names of your pods run: kubectl get pods

NAME         READY   STATUS    RESTARTS   AGE
webapp       1/1     Running   15         47h

then I changed the conflicting pod name and everything worked just fine.

Examples with Types:

// create a tree structure for an object. You can't do the same with interface because of lack of intersection (&)

type Tree<T> = T & { parent: Tree<T> };

// type to restrict a variable to assign only a few values. Interfaces don't have union (|)

type Choise = "A" | "B" | "C";

// thanks to types, you can declare NonNullable type thanks to a conditional mechanism.

type NonNullable<T> = T extends null | undefined ? never : T;

Examples with Interface:

// you can use interface for OOP and use 'implements' to define object/class skeleton

interface IUser {
    user: string;
    password: string;
    login: (user: string, password: string) => boolean;
}

class User implements IUser {
    user = "user1"
    password = "password1"

    login(user: string, password: string) {
        return (user == user && password == password)
    }
}

// you can extend interfaces with other interfaces

    interface IMyObject {
        label: string,
    }

    interface IMyObjectWithSize extends IMyObject{
        size?: number
    }

Raw arrays aren't resizable in C++.

You should be using something like a Vector class which does allow resizing..

std::vector allows you to resize it as well as allowing dynamic resizing when you add elements (often making the manual resizing unnecessary for adding).

Not my fiddle, but http://jsfiddle.net/maxisam/QrCXh/ shows the difference. The key piece is:

           scope:{
            /* NOTE: Normally I would set my attributes and bindings
            to be the same name but I wanted to delineate between 
            parent and isolated scope. */                
            isolatedAttributeFoo:'@attributeFoo',
            isolatedBindingFoo:'=bindingFoo',
            isolatedExpressionFoo:'&'
        }        

For ansible, and using hyphen, this worked for me:

    - name: free-ud-ssd-space-in-percent
      debug:
        var: clusterInfo.json.content["free-ud-ssd-space-in-percent"]

Use transform: scale(...); and add matching margin: -...px to compensate free space from scaling. (you can use * {outline: 1px solid}to see element boundaries).

You can specify the whole day by doing a range, like so:

WHERE bk_date >= TO_DATE('2012-03-18', 'YYYY-MM-DD')
AND bk_date <  TO_DATE('2012-03-19', 'YYYY-MM-DD')

More simply you can use TRUNC:

WHERE TRUNC(bk_date) = TO_DATE('2012-03-18', 'YYYY-MM-DD')

TRUNC without parameter removes hours, minutes and seconds from a DATE.

You can try also this (it works on PHP 5.* and 7):

$info = new SplFileInfo('test.zip');
echo $info->getExtension(); // ----- Output -----> zip

Tip: it returns an empty string if the file doesn't have an extension

The easiest way is to paste the following command:

In my experience, regex solutions have too many false positives and filter_var() solutions have false negatives (especially with all of the newer TLDs).

Instead, it's better to make sure the address has all of the required parts of an email address (user, "@" symbol, and domain), then verify that the domain itself exists.

There is no way to determine (server side) if an email user exists for an external domain.

This is a method I created in a Utility class:

public static function validateEmail($email)
{
    // SET INITIAL RETURN VARIABLES

        $emailIsValid = FALSE;

    // MAKE SURE AN EMPTY STRING WASN'T PASSED

        if (!empty($email))
        {
            // GET EMAIL PARTS

                $domain = ltrim(stristr($email, '@'), '@') . '.';
                $user   = stristr($email, '@', TRUE);

            // VALIDATE EMAIL ADDRESS

                if
                (
                    !empty($user) &&
                    !empty($domain) &&
                    checkdnsrr($domain)
                )
                {$emailIsValid = TRUE;}
        }

    // RETURN RESULT

        return $emailIsValid;
}

this bellow solution worked for me

use this code to redirect the page

echo "<script>alert('There are no fields to generate a report');document.location='admin/ahm/panel'</script>";

There are two options that I can think of, but without more details, I can't be sure which is the better:

#elementId {
    display: block;
}

This will force the element to a 'new line' if it's not on the same line as a floated element.

#elementId {
     clear: both;
}

This will force the element to clear the floats, and move to a 'new line.'

In the case of the element being on the same line as another that has position of fixed or absolute nothing will, so far as I know, force a 'new line,' as those elements are removed from the document's normal flow.

this.setState({abc: {xyz: 'new value'}}); will NOT work, as state.abc will be entirely overwritten, not merged.

This works for me:

this.setState((previousState) => {
  previousState.abc.xyz = 'blurg';
  return previousState;
});

Unless I'm reading the docs wrong, Facebook recommends the above format. https://facebook.github.io/react/docs/component-api.html

Additionally, I guess the most direct way without mutating state is to directly copy by using the ES6 spread/rest operator:

const newState = { ...this.state.abc }; // deconstruct state.abc into a new object-- effectively making a copy
newState.xyz = 'blurg';
this.setState(newState);

dataDb.Table.RemoveRange(dataDb.Table);
dataDb.SaveChanges();

As far as I can tell what you could do is "retire" your previous app and redirect all users to your new app. This procedure is not supported by Google (tsk... tsk...), but it could be implemented in four steps:

1. Change the current application to show a message to the users about the upgrade and redirect them to the new app listing. Probably a full screen message would do with some friendly text. This message could be triggered remotely ideally, but a cut-off date can be used too. (But then that will be a hard deadline for you, so be careful... ;))

2. Release the modified old app as an upgrade, maybe with some feature upgrades/bug fixes too, to "sweeten the deal" to the users. Still there is no guarantee that all users will upgrade, but probably the majority will do.

3. Prepare your new app with the updated package name and upload it to the store, then trigger the message in the old app (or just wait until it expires, if that was your choice).

4. Unpublish the old app in Play Store to avoid any new installs. Unpublishing an app doesn't mean the users who already installed it won't have access to it anymore, but at least the potential new users won't find it on the market.

Not ideal and can be annoying to the users, sometimes even impossible to implement due to the status/possibilities of the app. But since Google left us no choice this is the only way to migrate the users of the old apps to a "new" one (even if it is not really new). Not to mention that if you don't have access to the sources and code signing details for the old app then all you could do is hoping that he users will notice the new app...

If anybody figured out a better way by all means: please do tell.

I had the same issue after installing the java-1.8.0-openjdk package on an AWS Linux AMI. The incorrect assumption I made, was that because the file ended in openjdk it would be the jdk version. This is not the case.

The openjdk install page explains everything clearly.

The java-1.8.0-openjdk package contains just the Java Runtime Environment. If you want to develop Java programs then install the java-1.8.0-openjdk-devel package.

If you've already installed the java-1.8.0-openjdk package, just leave it and the JAVA_HOME value if it's working for the JRE and install the java-1.8.0-openjdk-devel package using yum install java-1.8.0-openjdk-devel -y.

There is one example where in actually kills your performance.

If you use in on a O(1) container that only implements __getitem__ and has_key() but not __contains__ you will turn an O(1) search into an O(N) search (as in falls back to a linear search via __getitem__).

Fix is obviously trivial:

def __contains__(self, x):
    return self.has_key(x)

It means you have a null reference somewhere in there. Can you debug the app and stop the debugger when it gets here and investigate? Probably img1 is null or ConfigurationManager.AppSettings.Get("Url") is returning null.

The problem must be with the value Model.Id which is null. You can confirm by assigning a value, e.g

@{         
     var blogPostId = 1;          
 }

If the error disappers, then u need to make sure that your model Id has a value before passing it to the view

import csv
dic = {firstcol,secondcol} #dictionary
csv = open('result.csv', "w") 
for key in dic.keys():
    row ="\n"+ str(key) + "," + str(dic[key]) 
    csv.write(row)

If (Not IsNull(Me.id.Value)) Then
DoCmd.GoToRecord , , acNext
End If

Hi, you need to put this in form activate, and have an id field named id...

this way it passes until it reaches the one without id (AKA new one)...

Security of the OAuth 1.0 protocol (RFC 5849) relies on the assumption that a secret key embedded in a client application can be kept confidential. However, the assumption is naive.

In OAuth 2.0 (RFC 6749), such a naive client application is called a confidential client. On the other hand, a client application in an environment where it is difficult to keep a secret key confidential is called a public client. See 2.1. Client Types for details.

In that sense, OAuth 1.0 is a specification only for confidential clients.

"OAuth 2.0 and the Road to Hell" says that OAuth 2.0 is less secure, but there is no practical difference in security level between OAuth 1.0 clients and OAuth 2.0 confidential clients. OAuth 1.0 requires to compute signature, but it does not enhance security if it is already assured that a secret key on the client side can be kept confidential. Computing signature is just a cumbersome calculation without any practical security enhancement. I mean, compared to the simplicity that an OAuth 2.0 client connects to a server over TLS and just presents client_id and client_secret, it cannot be said that the cumbersome calculation is better in terms of security.

In addition, RFC 5849 (OAuth 1.0) does not mention anything about open redirectors while RFC 6749 (OAuth 2.0) does. That is, oauth_callback parameter of OAuth 1.0 can become a security hole.

Therefore, I don't think OAuth 1.0 is more secure than OAuth 2.0.

OAuth 1.0 security relies on signature computation. A signature is computed using a secret key where a secret key is a shared key for HMAC-SHA1 (RFC 5849, 3.4.2) or a private key for RSA-SHA1 (RFC 5849, 3.4.3). Anyone who knows the secret key can compute the signature. So, if the secret key is compromised, complexity of signature computation is meaningless however complex it is.

This means OAuth 1.0 security relies not on the complexity and the logic of signature computation but merely on the confidentiality of a secret key. In other words, what is needed for OAuth 1.0 security is only the condition that a secret key can be kept confidential. This may sound extreme, but signature computation adds no security enhancement if the condition is already satisfied.

Likewise, OAuth 2.0 confidential clients rely on the same condition. If the condition is already satisfied, is there any problem in creating a secure connection using TLS and sending client_id and client_secret to an authorization server through the secured connection? Is there any big difference in security level between OAuth 1.0 and OAuth 2.0 confidential clients if both rely on the same condition?

I cannot find any good reason for OAuth 1.0 to blame OAuth 2.0. The fact is simply that (1) OAuth 1.0 is just a specification only for confidential clients and (2) OAuth 2.0 has simplified the protocol for confidential clients and supported public clients, too. Regardless of whether it is known well or not, smartphone applications are classified as public clients (RFC 6749, 9), which benefit from OAuth 2.0.

N.B. - this question and answer relate to the 2000 version of SQL Server. In later versions, the restriction on INSERT INTO @table_variable ... EXEC ... were lifted and so it doesn't apply for those later versions.

You'll have to switch to a temp table:

CREATE TABLE #tmp (code varchar(50), mount money)
DECLARE @q nvarchar(4000)
SET @q = 'SELECT coa_code, amount FROM T_Ledger_detail'

INSERT INTO  #tmp (code, mount)
EXEC sp_executesql (@q)

SELECT * from #tmp

From the documentation:

A table variable behaves like a local variable. It has a well-defined scope, which is the function, stored procedure, or batch in which it is declared.

Within its scope, a table variable may be used like a regular table. It may be applied anywhere a table or table expression is used in SELECT, INSERT, UPDATE, and DELETE statements. However, table may not be used in the following statements:

INSERT INTO table_variable EXEC stored_procedure

SELECT select_list INTO table_variable statements.

Here is the ES6 version:

let getTimeAfter30Mins = () => {
  let timeAfter30Mins = new Date();
  timeAfter30Mins = new Date(timeAfter30Mins.setMinutes(timeAfter30Mins.getMinutes() + 30));
};

Call it like:

getTimeAfter30Mins();

You cannot decrypt this password again but there is another method named "pwdcompare". Here is a example how to use it with SQL syntax:

USE TEMPDB
GO
declare @hash varbinary (255)
CREATE TABLE tempdb..h (id_num int, hash varbinary (255))
SET @hash = pwdencrypt('123') -- encryption
INSERT INTO tempdb..h (id_num,hash) VALUES (1,@hash)
SET @hash = pwdencrypt('123')
INSERT INTO tempdb..h (id_num,hash) VALUES (2,@hash)
SELECT TOP 1 @hash = hash FROM tempdb..h WHERE id_num = 2
SELECT pwdcompare ('123', @hash) AS [Success of check] -- Comparison
SELECT * FROM tempdb..h
INSERT INTO tempdb..h (id_num,hash) 
VALUES (3,CONVERT(varbinary (255),
0x01002D60BA07FE612C8DE537DF3BFCFA49CD9968324481C1A8A8FE612C8DE537DF3BFCFA49CD9968324481C1A8A8))
SELECT TOP 1 @hash = hash FROM tempdb..h WHERE id_num = 3
SELECT pwdcompare ('123', @hash) AS [Success of check] -- Comparison
SELECT * FROM tempdb..h
DROP TABLE tempdb..h
GO

Simplest solution would be to use tool which allows you to directly specify ranges, like gnu shuf

shuf -i1-10 -n1

If you want to use $RANDOM, it would be more precise to throw out the last 8 numbers in 0...32767, and just treat it as 0...32759, since taking 0...32767 mod 10 you get the following distribution

0-8 each: 3277 
8-9 each: 3276

So, slightly slower but more precise would be

while :; do ran=$RANDOM; ((ran < 32760)) && echo $(((ran%10)+1)) && break; done 

You can simply use the zoom property:

#myContainer{
    zoom: 0.5;
    -moz-transform: scale(0.5);
}

Where myContainer contains all the elements you're editing. This is supported in all major browsers.

There are certain tools that provide dependency injection through their library, for example in .net we have ninject Library .

If you are going further in java then spring provides this capabilities.

Loosly coupled objects can be made by introducing Interfaces in your code, thats what these sources do.

Say in your code you are writing

Myclass m = new Myclass();

now this statement in your method says that you are dependent on myclass this is called a tightly coupled. Now you provide some constructor injection , or property injection and instantiating object then it will become loosly coupled.

I see two problems:

DOUBLE(10) precision definitions need a total number of digits, as well as a total number of digits after the decimal:

DOUBLE(10,8) would make be ten total digits, with 8 allowed after the decimal.

Also, you'll need to specify your id column as a key :

CREATE TABLE transactions( 
id int NOT NULL AUTO_INCREMENT, 
location varchar(50) NOT NULL, 
description varchar(50) NOT NULL, 
category varchar(50) NOT NULL, 
amount double(10,9) NOT NULL, 
type varchar(6) NOT NULL,  
notes varchar(512), 
receipt int(10), 
PRIMARY KEY(id) );

I looked at several solutions but all failed with scroll and select text being the biggest confusion. Instead of scrolling right I was closing boxes and such.

I just finished my implementation that does it all for me.

It is MIT so do what you want - and yes, it is really simple - 800 bytes minified. You can check it out on my (under-development) site https://cyrex.tech - swiperight on touch-devices should dismiss popup windows.

A weird thing I found was that the environment variable SYSTEMROOT must be set otherwise getaddrinfo() will fail on Windows 10.

This is a very c# type of code:

var bks: Book[] = new Book[2];

In Javascript / Typescript you don't allocate memory up front like that, and that means something completely different. This is how you would do what you want to do:

var bks: Book[] = [];
bks.push(new Book());
bks[0].Author = "vamsee";
bks[0].BookId = 1;
return bks.length;

Now to explain what new Book[2]; would mean. This would actually mean that call the new operator on the value of Book[2]. e.g.:

Book[2] = function (){alert("hey");}
var foo = new Book[2]

and you should see hey. Try it

Recently I wrote a palindrome program which doesn't use StringBuilder. A late answer but this might come in handy to some people.

public boolean isPalindrome(String value) {
    boolean isPalindrome = true;
    for (int i = 0 , j = value.length() - 1 ; i < j ; i ++ , j --) {
        if (value.charAt(i) != value.charAt(j)) {
            isPalindrome = false;
        }
    }
    return isPalindrome;
}

make copy of your original list, iterate over it, see the modified code below

for a in myarr[:]:
      if somecond(a):
          myarr.append(newObj())

This is the equivalent of append and extend using the + operator:

>>> x = [1,2,3]
>>> x
[1, 2, 3]
>>> x = x + [4,5,6] # Extend
>>> x
[1, 2, 3, 4, 5, 6]
>>> x = x + [[7,8]] # Append
>>> x
[1, 2, 3, 4, 5, 6, [7, 8]]

I have solved this problem,puttygen is a third-party software, ssh key which generated by it didn't be used directly, so you must make some changes. For example, it look like this

---- BEGIN SSH2 PUBLIC KEY ----
Comment: "rsa-key-20170502"
AAAAB3NzaC1yc2EAAAABJQAAAQEAr4Ffd3LD1pa7KVSBDU+lq0M7vNvLp6TewkP7
*******C4eq1cdJACBPyjqUCoz00r+LqkGA6sIFGooeVuUXTOxbYULuNQ==
---- END SSH2 PUBLIC KEY ---- 

I omit some of the alphabets in the middle, replaced by *, if not, StackOverflow told me that the code format is wrong, do not let me post?

this is my ssh key generated by puttygen, you must change to this

ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAQEAr4Ffd3LD1pa7KVSBDU+lq0M7vNvLp6TewkP7wfvKGWWR7wxA8GEXJsM01FQw5hYWbNF0CDI7nCMXDUEDOzO1xKtNoaidlLA0qGl67bHaF5t+0mE+dZBGqK7jG9L8/KU/b66/tuZnqFqBjLkT+lS8MDo1okJOScuLSilk9oT5ZiqxsD24sdEcUE62S8Qwu7roVEAWU3hHNpnMK+1szlPBCVpbjcQTdiv1MjsOHJXY2PWx6DAIBii+/N+IdGzoFdhq+Yo/RGWdr1Zw/LSwqKDq1SmrpToW9uWVdAxeC4eq1cdJACBPyjqUCoz00r+LqkGA6sIFGooeVuUXTOxbYULuNQ== yourname@hostname

In my case, I have deleted some comments, such as

---- BEGIN SSH2 PUBLIC KEY ----
Comment: "rsa-key-20170502"
---- END SSH2 PUBLIC KEY ----

and add ssh-rsa at the beginning, add yourname@hostname at the last. note: not delete== in the last and you must change "yourname" and "hostname" for you, In my case, is uaskh@mycomputer,yourname is that you want to log in your vps .when all these things have done,you could to upload public-key to uaskh's home~/.ssh/authorized_keys by cat public-key >> ~/.ssh/authorized_keys then sudo chmod 700 ~/.ssh sudo chmod 600 ~/.ssh/authorized_keys then you must to modify /etc/ssh/sshd_config, RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile .ssh/authorized_keys my operating system is CentOS 7,This is my first time to anwser question,I will try my efforts to do ,Thank you!

Add new WebProxy() for the proxy setting , where you are creating a web request.

Example :-

  string url =  "Your URL";
  System.Net.WebRequest req = System.Net.WebRequest.Create(url);
  req.Proxy = new WebProxy();
  System.Net.WebResponse resp = req.GetResponse();

Where req.Proxy = new WebProxy() handle the proxy setting & helps the code to work fine.

I think you have putted e.preventDefault(); before ajax call that's why its prevent calling of that function and your Ajax call will not call.

So try to remove that e.prevent Default() before Ajax call and add it to the after Ajax call.

Use the true or false commands immediately before your return, then return with no parameters. The return will automatically use the value of your last command.

Providing arguments to return is inconsistent, type specific and prone to error if you are not using 1 or 0. And as previous comments have stated, using 1 or 0 here is not the right way to approach this function.

#!/bin/bash

function test_for_cat {
    if [ $1 = "cat" ];
    then
        true
        return
    else
        false
        return
    fi
}

for i in cat hat;
do
    echo "${i}:"
    if test_for_cat "${i}";
    then
        echo "- True"
    else
        echo "- False"
    fi
done

Output:

$ bash bash_return.sh

cat:
- True
hat:
- False

Me, I'd do ('%f' % x).rstrip('0').rstrip('.') -- guarantees fixed-point formatting rather than scientific notation, etc etc. Yeah, not as slick and elegant as %g, but, it works (and I don't know how to force %g to never use scientific notation;-).

The documentation of the file module says

If state=file, the file will NOT be created if it does not exist, see the copy or template module if you want that behavior.

So we use the copy module, using force=no to create a new empty file only when the file does not yet exist (if the file exists, its content is preserved).

- name: ensure file exists
  copy:
    content: ""
    dest: /etc/nologin
    force: no
    group: sys
    owner: root
    mode: 0555

This is a declarative and elegant solution.

string name= "abc";
IList<string> strList = new List<string>() { "abc",  "def", "ghi", "jkl", "mno" };
if (strList.Contains(name))
{
  Console.WriteLine("Got It");
}

/////////////////   OR ////////////////////////

IList<int> num = new List<int>();
num.Add(10);
num.Add(20);
num.Add(30);
num.Add(40);

Console.WriteLine(num.Count);   // to count the total numbers in the list

if(num.Contains(20)) {
    Console.WriteLine("Got It");    // if condition to find the number from list
}

I was having a similar issue - like the original poster, I wanted to automate a file upload but I couldn't figure out how. Because this is on a register terminal at my family's store, I didn't want to install powershell (although that looks like an easy option), just wanted a simple .bat file to do this. This is pretty much what grawity and another user said; I'm new to this stuff, so here's a more detailed example and explanation (thanks also to http://www.howtogeek.com/howto/windows/how-to-automate-ftp-uploads-from-the-windows-command-line/ who explains how to do it with just one .bat file.)

Essentially you need 2 files - one .bat and one .txt. The .bat tells ftp.exe what switches to use. The .txt gives a list of commands to ftp.exe. In the text file put this:

username
password
cd whereverYouWantToPutTheFile
lcd whereverTheFileComesFrom
put C:\InventoryExport\inventory.test (or your file path)
bye

Save that wherever you want. In the BAT file put:

ftp.exe -s:C:\Windows\System32\test.txt destinationIP
pause

Obviously change the path after the -s: to wherever your text file is. Take out the pause when you're actually running it - it's just so you can see any errors. Of course, you can use "get" or any other ftp command in the .txt file to do whatever you need to do.

I'm not positive that you need the lcd command in the text file, like I said I'm new to using command line for this type of thing, but this is working for me.

Also had 401's from Nexus. Having tried all the suggestions above and more without success I eventually found that it was a Jenkins setting that was in error.

In the Jenkins configuration for the failing project, we have a section in the 'Post Build' actions entitled 'Deploy Artifacts To Maven Repository'. This has a 'Repository ID' field which was set to the wrong value. It has to be the same as the repository ID in settings.xml for Jenkins to read the user and password fields:

 <servers>
    <server>
      <id>snapshot-repository</id>  <!-- must match this -->
      <username>deployment</username>
      <password>password</password>
    </server>
  </servers>

Json.NET does this...

Dictionary<string, string> values = new Dictionary<string, string>();
values.Add("key1", "value1");
values.Add("key2", "value2");

string json = JsonConvert.SerializeObject(values);
// {
//   "key1": "value1",
//   "key2": "value2"
// }

I found this very annoying bug while converting EmployeeID values with ISNUMERIC:

SELECT DISTINCT [EmployeeID],
ISNUMERIC(ISNULL([EmployeeID], '')) AS [IsNumericResult],

CASE WHEN COALESCE(NULLIF(tmpImport.[EmployeeID], ''), 'Z')
    LIKE '%[^0-9]%' THEN 'NonNumeric' ELSE 'Numeric'
END AS [IsDigitsResult]
FROM [MyTable]

This returns:

EmployeeID IsNumericResult MyCustomResult
---------- --------------- --------------
           0               NonNumeric
00000000c  0               NonNumeric
00D026858  1               NonNumeric

Hope this helps!

Authoring a homegrown sed replacement in pure Python with no external commands or additional dependencies is a noble task laden with noble landmines. Who would have thought?

Nonetheless, it is feasible. It's also desirable. We've all been there, people: "I need to munge some plaintext files, but I only have Python, two plastic shoelaces, and a moldy can of bunker-grade Maraschino cherries. Help."

In this answer, we offer a best-of-breed solution cobbling together the awesomeness of prior answers without all of that unpleasant not-awesomeness. As plundra notes, David Miller's otherwise top-notch answer writes the desired file non-atomically and hence invites race conditions (e.g., from other threads and/or processes attempting to concurrently read that file). That's bad. Plundra's otherwise excellent answer solves that issue while introducing yet more – including numerous fatal encoding errors, a critical security vulnerability (failing to preserve the permissions and other metadata of the original file), and premature optimization replacing regular expressions with low-level character indexing. That's also bad.

Awesomeness, unite!

import re, shutil, tempfile

def sed_inplace(filename, pattern, repl):

    pattern_compiled = re.compile(pattern)

    # For portability, NamedTemporaryFile() defaults to mode "w+b" (i.e., binary

when you set the density to 96, doesn't it look good?

Do make sure that you haven't written your unit tests in a .NET Standard 2.0 Class Library. The visualstudio runner does not support running tests in netstandard2.0 class libraries at the time of this writing.

Check here for the Test Runner Compatibility matrix:

The simple one line solution is

datediff(dd,'2010-12-31 15:13:48.593','2010-12-31 00:00:00.000')=0

datediff(dd,'2010-12-31 15:13:48.593','2010-12-31 00:00:00.000')<=1

datediff(dd,'2010-12-31 15:13:48.593','2010-12-31 00:00:00.000')>=1

You can try various option with this other than "dd"

best to use crypt for password storing in DB

example code :

$crypted_pass = crypt($password);

//$pass_from_login is the user entered password
//$crypted_pass is the encryption
if(crypt($pass_from_login,$crypted_pass)) == $crypted_pass)
{
   echo("hello user!")
}

documentation :

http://www.php.net/manual/en/function.crypt.php

I think there is a semantic problem here. In my view, a user can have a (but only one) favourite recipe to prepare a specific menu. (The OP has menu and recipe mixed up; if I am wrong: please interchange MenuId and RecipeId below) That implies that {user,menu} should be a unique key in this table. And it should point to exactly one recipe. If the user has no favourite recipe for this specific menu no row should exist for this {user,menu} key pair. Also: the surrogate key (FaVouRiteId) is superfluous: composite primary keys are perfectly valid for relational-mapping tables.

That would lead to the reduced table definition:

CREATE TABLE Favorites
( UserId uuid NOT NULL REFERENCES users(id)
, MenuId uuid NOT NULL REFERENCES menus(id)
, RecipeId uuid NOT NULL REFERENCES recipes(id)
, PRIMARY KEY (UserId, MenuId)
);

Adding to previous solutions, you can also specify the font size relative to the base_size included in themes such as theme_bw() (where base_size is 11) using the rel() function.

For example:

ggplot(mtcars, aes(disp, mpg)) +
  geom_point() +
  theme_bw() +
  theme(axis.text.x=element_text(size=rel(0.5), angle=90))

Use -t on ls. e.g:.

ls -tr

or

ls -ltr

In a single line you could do:

private static File[] bar(){
    return new File[]{};
}

For Oracle SQL Developer I was able to calculate the difference in years using the below line of SQL. This was to get Years that were within 0 to 10 years difference. You can do a case like shown in some of the other responses to handle your ifs as well. Happy Coding!

TRUNC((MONTHS_BETWEEN(<DATE_ONE>, <DATE_TWO>) * 31) / 365) > 0 and TRUNC((MONTHS_BETWEEN(<DATE_ONE>, <DATE_TWO>) * 31) / 365) < 10

If with the word "anywhere" you mean without having an explicit Context (for example from a background thread) you should define a class in your project like:

public class MyApp extends Application {
    private static MyApp instance;

    public static MyApp getInstance() {
        return instance;
    }

    public static Context getContext(){
        return instance;
        // or return instance.getApplicationContext();
    }

    @Override
    public void onCreate() {
        instance = this;
        super.onCreate();
    }
}

Then in your manifest you need to add this class to the Name field at the Application tab. Or edit the xml and put

<application
    android:name="com.example.app.MyApp"
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    .......
    <activity
        ......

and then from anywhere you can call

String packagename= MyApp.getContext().getPackageName();

Hope it helps.

To check if one or more columns all exist, you can use set.issubset, as in:

if set(['A','C']).issubset(df.columns):
   df['sum'] = df['A'] + df['C']                

As @brianpck points out in a comment, set([]) can alternatively be constructed with curly braces,

if {'A', 'C'}.issubset(df.columns):

See this question for a discussion of the curly-braces syntax.

Or, you can use a list comprehension, as in:

if all([item in df.columns for item in ['A','C']]):

The command has to be entered in the directory of the repository. The error is complaining that your current directory isn't a git repo

1. Are you in the right directory? Does typing ls show the right files?
2. Have you initialized the repository yet? Typed git init? (git-init documentation)

Either of those would cause your error.

If the bytes use an appropriate character encoding already; you could print them directly:

sys.stdout.buffer.write(data)

or

nwritten = os.write(sys.stdout.fileno(), data)  # NOTE: it may write less than len(data) bytes

Having a script or even a subsystem of an application for a network protocol debugging, it's desired to see what request-response pairs are exactly, including effective URLs, headers, payloads and the status. And it's typically impractical to instrument individual requests all over the place. At the same time there are performance considerations that suggest using single (or few specialised) requests.Session, so the following assumes that the suggestion is followed.

requests supports so called event hooks (as of 2.23 there's actually only response hook). It's basically an event listener, and the event is emitted before returning control from requests.request. At this moment both request and response are fully defined, hence can be logged.

import logging

import requests


logger = logging.getLogger('httplogger')

def logRoundtrip(response, *args, **kwargs):
    extra = {'req': response.request, 'res': response}
    logger.debug('HTTP roundtrip', extra=extra)

session = requests.Session()
session.hooks['response'].append(logRoundtrip)

That's basically how to log all HTTP round-trips of a session.

Formatting HTTP round-trip log records

For the logging above to be useful there can be specialised logging formatter that understands req and res extras on logging records. It can look like this:

import textwrap

class HttpFormatter(logging.Formatter):   

    def _formatHeaders(self, d):
        return '\n'.join(f'{k}: {v}' for k, v in d.items())

    def formatMessage(self, record):
        result = super().formatMessage(record)
        if record.name == 'httplogger':
            result += textwrap.dedent('''
                ---------------- request ----------------
                {req.method} {req.url}
                {reqhdrs}

                {req.body}
                ---------------- response ----------------
                {res.status_code} {res.reason} {res.url}
                {reshdrs}

                {res.text}
            ''').format(
                req=record.req,
                res=record.res,
                reqhdrs=self._formatHeaders(record.req.headers),
                reshdrs=self._formatHeaders(record.res.headers),
            )

        return result

formatter = HttpFormatter('{asctime} {levelname} {name} {message}', style='{')
handler = logging.StreamHandler()
handler.setFormatter(formatter)
logging.basicConfig(level=logging.DEBUG, handlers=[handler])

Now if you do some requests using the session, like:

session.get('https://httpbin.org/user-agent')
session.get('https://httpbin.org/status/200')

The output to stderr will look as follows.

A GUI way

When you have a lot of queries, having a simple UI and a way to filter records comes at handy. I'll show to use Chronologer for that (which I'm the author of).

First, the hook has be rewritten to produce records that logging can serialise when sending over the wire. It can look like this:

def logRoundtrip(response, *args, **kwargs): 
    extra = {
        'req': {
            'method': response.request.method,
            'url': response.request.url,
            'headers': response.request.headers,
            'body': response.request.body,
        }, 
        'res': {
            'code': response.status_code,
            'reason': response.reason,
            'url': response.url,
            'headers': response.headers,
            'body': response.text
        },
    }
    logger.debug('HTTP roundtrip', extra=extra)

session = requests.Session()
session.hooks['response'].append(logRoundtrip)

Second, logging configuration has to be adapted to use logging.handlers.HTTPHandler (which Chronologer understands).

import logging.handlers

chrono = logging.handlers.HTTPHandler(
  'localhost:8080', '/api/v1/record', 'POST', credentials=('logger', ''))
handlers = [logging.StreamHandler(), chrono]
logging.basicConfig(level=logging.DEBUG, handlers=handlers)

Finally, run Chronologer instance. e.g. using Docker:

docker run --rm -it -p 8080:8080 -v /tmp/db \
    -e CHRONOLOGER_STORAGE_DSN=sqlite:////tmp/db/chrono.sqlite \
    -e CHRONOLOGER_SECRET=example \
    -e CHRONOLOGER_ROLES="basic-reader query-reader writer" \
    saaj/chronologer \
    python -m chronologer -e production serve -u www-data -g www-data -m

And run the requests again:

session.get('https://httpbin.org/user-agent')
session.get('https://httpbin.org/status/200')

The stream handler will produce:

DEBUG:urllib3.connectionpool:Starting new HTTPS connection (1): httpbin.org:443
DEBUG:urllib3.connectionpool:https://httpbin.org:443 "GET /user-agent HTTP/1.1" 200 45
DEBUG:httplogger:HTTP roundtrip
DEBUG:urllib3.connectionpool:https://httpbin.org:443 "GET /status/200 HTTP/1.1" 200 0
DEBUG:httplogger:HTTP roundtrip

Now if you open http://localhost:8080/ (use "logger" for username and empty password for the basic auth popup) and click "Open" button, you should see something like:

Also you might want to log in via browser and get the command with all headers including cookies:

Open the Network tab of Developer Tools, log in, navigate to the needed page, use "Copy as cURL".

RollingFileAppender does this. You just need to set maxBackupIndex to the highest value for the backup file.

My preferred method for centering blocks of information while maintaining responsiveness (mobile compatibility) is to place two empty span1 divs before and after the content you wish to center.

<div class="row-fluid">

    <div class="span1">
    </div>

        <div class="span10">
          <div class="hero-unit">
            <h1>Reading Resources</h1>
            <p>Read here...</p>
          </div>
        </div><!--/span-->

    <div class="span1">
    </div>

</div><!--/row-->

To update the local list of remote branches:

git remote update origin --prune

To show all local and remote branches that (local) Git knows about

git branch -a

The best way to do this is this:

datetimepicker.Format = DatetimePickerFormat.Custom;
datetimepicker.CustomFormat = "HH:mm tt";
datetimepicker.ShowUpDowm = true;

Not sure where you add the json but if i do it like this with angular it works without the requestBody: angluar:

    const params: HttpParams = new HttpParams().set('str1','val1').set('str2', ;val2;);
    return this.http.post<any>( this.urlMatch,  params , { observe: 'response' } );

java:

@PostMapping(URL_MATCH)
public ResponseEntity<Void> match(Long str1, Long str2) {
  log.debug("found: {} and {}", str1, str2);
}

SERIOUS DISCLAIMER

This solution has a serious security flaw. Please use at your own risk.
Have a look at the comments on this post, and look at all the answers to this question.

OK, I had to go to the customer premises and found a solution. I:

• Exported the keystore that holds the signing keys in PKCS #12 format
• Opened control panel Java -> Security tab
• Clicked Manage certificates
• Imported this new keystore as a secure site CA

Then I opened the JAWS application without any warning. This is a little bit cumbersome, but much cheaper than buying a signed certificate!

I use a singleton class, so that I can mock the class and change the constants if necessary for testing. The constants class looks like this:

#import <Foundation/Foundation.h>

@interface iCode_Framework : NSObject

@property (readonly, nonatomic) unsigned int iBufCapacity;
@property (readonly, nonatomic) unsigned int iPort;
@property (readonly, nonatomic) NSString * urlStr;

@end

#import "iCode_Framework.h"

static iCode_Framework * instance;

@implementation iCode_Framework

@dynamic iBufCapacity;
@dynamic iPort;
@dynamic urlStr;

- (unsigned int)iBufCapacity
{
    return 1024u;
};

- (unsigned int)iPort
{
    return 1978u;
};

- (NSString *)urlStr
{
    return @"localhost";
};

+ (void)initialize
{
    if (!instance) {
        instance = [[super allocWithZone:NULL] init];
    }
}

+ (id)allocWithZone:(NSZone * const)notUsed
{
    return instance;
}

@end

And it is used like this (note the use of a shorthand for the constants c - it saves typing [[Constants alloc] init] every time):

#import "iCode_FrameworkTests.h"
#import "iCode_Framework.h"

static iCode_Framework * c; // Shorthand

@implementation iCode_FrameworkTests

+ (void)initialize
{
    c  = [[iCode_Framework alloc] init]; // Used like normal class; easy to mock!
}

- (void)testSingleton
{
    STAssertNotNil(c, nil);
    STAssertEqualObjects(c, [iCode_Framework alloc], nil);
    STAssertEquals(c.iBufCapacity, 1024u, nil);
}

@end

As long as Event_ID is Integer, do this:

INSERT INTO Table (foo, bar, Event_ID)
SELECT foo, bar, (Event_ID + 155)
  FROM Table
WHERE Event_ID = "120"

sudo make uninstall did the trick for me using the Ruby 2.4 tar from the official downloads page.

With the addition of Python 3, here is an updated code that works:

import numpy as n
import scipy as s
import matplotlib.pylab as p #pylab is part of matplotlib

xa=0.252
xb=1.99

C=n.linspace(xa,xb,100)
print(C)
iter=1000
Y = n.ones(len(C))

for x in range(iter):
    Y = Y**2 - C   #get rid of early transients

for x in range(iter): 
    Y = Y**2 - C
    p.plot(C,Y, '.', color = 'k', markersize = 2)

p.show()

call concat and pass param axis=1 to concatenate column-wise:

In [5]:

pd.concat([df_a,df_b], axis=1)

There is a useful guide to the various methods of merging, joining and concatenating online.

For example, as you have no clashing columns you can merge and use the indices as they have the same number of rows:

In [6]:

df_a.merge(df_b, left_index=True, right_index=True)
Out[6]:
        AAseq Biorep  Techrep Treatment     mz      AAseq1 Biorep1  Techrep1  \
0  ELVISLIVES      A        1         C  500.0  ELVISLIVES       A         1

2  ELVISLIVES      A        1         C  501.0  ELVISLIVES       A         1

1          C   1050  
2          C   1010  

And for the same reasons as above a simple join works too:

In [7]:

df_a.join(df_b)
Out[7]:
        AAseq Biorep  Techrep Treatment     mz      AAseq1 Biorep1  Techrep1  \

2  ELVISLIVES      A        1         C  501.0  ELVISLIVES       A         1   

  Treatment1  inte1

For those of you who don't want to get rid of the bouncing but just to know when it stops (for example to start some calculation of screen distances), you can do the following (container is the overflowing container element):

    const isBouncing = this.container.scrollTop < 0 ||
    this.container.scrollTop + this.container.offsetHeight >
        this.container.scrollHeight

The top-scoring answer has the right idea, but the API seems to have evolved so that it no longer works as when it was first written, in 2015.

In place of this:

from OpenSSL import SSL
context = SSL.Context(SSL.PROTOCOL_TLSv1_2)
context.use_privatekey_file('server.key')
context.use_certificate_file('server.crt')

I used this, with Python 3.7.5:

import ssl
context = ssl.SSLContext()
context.load_cert_chain('fullchain.pem', 'privkey.pem')

and then supplied the SSL context in the Flask.run call as it said:

app.run(…, ssl_context=context)

(My server.crt file is called fullchain.pem and my server.key is called privkey.pem. These files were supplied to me by my LetsEncrypt Certbot.)

Use:

System.Configuration.ConfigurationSettings.AppSettings["MyKey"];

AppSettings has been deprecated and is now considered obsolete (link).

In addition, the appSettings section of the app.config has been replaced by the applicationSettings section.

As someone else mentioned, you should be using System.Configuration.ConfigurationManager (link) which is new for .NET 2.0.

I don't have enough reputation to comment on any answer. In one of the comments, someone has asked how to ignore the hidden folders in the list. Below is how you can do this.

dir /b /AD-H

Late to the game, but most of these seem quite complicated.

Here's how I did it:

var originalSelect = $('#select-2').html();

// filter select-2 on select-1 change
$('#select-1').change(function (e) {

    var selected = $(this).val();

    // reset select ready for filtering
    $('#select-2').html(originalCourseSelect);

    if (selected) {
        // filter
        $('#select-2 option').not('.t' + selected).remove();
    }

});

markup of select-1:

<select id='select-1'>
<option value=''>Please select</option>
<option value='1'>One</option>
<option value='2'>Two</option>
</select>

markup of select-2:

<select id='select-2'>
<option class='t1'>One</option>
<option class='t2'>Two</option>
<option>Always visible</option>
</select>

A ListView is a specialized ListBox (that is, it inherits from ListBox). It allows you to specify different views rather than a straight list. You can either roll your own view, or use GridView (think explorer-like "details view"). It's basically the multi-column listbox, the cousin of windows form's listview.

If you don't need the additional capabilities of ListView, you can certainly use ListBox if you're simply showing a list of items (Even if the template is complex).

Reload is easy. You should use:

location.reload(true);

And detecting back is :

window.history.pushState('', null, './');
  $(window).on('popstate', function() {
   location.reload(true);
});

The following is a jQuery function call:

$(...);

Which is the "jQuery function." $ is a function, and $(...) is you calling that function.

The first parameter you've supplied is the following:

function() {}

The parameter is a function that you specified, and the $ function will call the supplied method when the DOM finishes loading.

I just got that problem when converting from % formatting to .format().

Previous code:

"SET !TIMEOUT_STEP %{USER_TIMEOUT_STEP}d" % {'USER_TIMEOUT_STEP' = 3}

Problematic syntax:

"SET !TIMEOUT_STEP {USER_TIMEOUT_STEP}".format('USER_TIMEOUT_STEP' = 3)

The problem is that format is a function that needs parameters. They cannot be strings. That is one of worst python error messages I've ever seen.

Corrected code:

"SET !TIMEOUT_STEP {USER_TIMEOUT_STEP}".format(USER_TIMEOUT_STEP = 3)

My Point , IN this arent way asking developer to create all environment related in single go, resulting in risk of exposing Production Configuration to end developer

as per 12-Factor, shouldnt be enviornment specific reside in Enviornment only .

How do we do for CI CD

• Build Spring one time and promote to aother environment, in that case, if we have spring jar has all environment, it iwll security risk, having all environment variable in GIT

i've been with this issue using elementary OS loki. For like one day and i solved it restarting the adb using this command:

./adb kill-server

and

./adb start-server

You need to be in the Sdk folder >Platform Tools

Now, restart your phone this will restart all the process in your phone.

And that's how i fixed it.

Clean project,Clean build folder,Restart Xcode. i just remove path at project goto > Build Settings > Search the keyword. Swift Compiler - General -> Objective-C Bridging header worked for me.

With C++11 you might use a lambda to get a slightly more compact code and in place usage:

bool to_convert{true};
auto bool_to_string = [](bool b) -> std::string {
    return b ? "true" : "false";
};
std::string str{"string to print -> "};
std::cout<<str+bool_to_string(to_convert);

Prints:

string to print -> true

sounds like the 'first line' you're talking of is your table-header - so you realy should think of using thead and tbody in your markup (click here) which would result in 'better' markup (semantically correct, useful for things like screenreaders) and easier, cross-browser-friendly possibilitys for css-selection (table thead ... { ... })
