Programs & Examples On #Http error

Not necessarily the most compact way of doing this, but quite clean IMO

if(json == null) {
    throw new BadThingException();
}
...

@ExceptionHandler(BadThingException.class)
@ResponseStatus(value = HttpStatus.BAD_REQUEST)
public @ResponseBody MyError handleException(BadThingException e) {
    return new MyError("That doesnt work");
}

Edit you can use @ResponseBody in the exception handler method if using Spring 3.1+, otherwise use a ModelAndView or something.

If you get the above problem on windows server 2008 you may need to enable ASP. To do so, follow these steps:

Add an 'Application Server' role:

1. Click Start, point to Control Panel, click Programs, and then click Turn Windows features on or off.
2. Right-click Server Manager, select Add Roles.
3. On the Add Roles Wizard page, select Application Server, click Next three times, and then click Install. Windows Server installs the new role.

Then, add a 'Web Server' role:

1. Web Server Role (IIS): in ServerManager, Roles, if the Web Server (IIS) role does not exist then add it.
2. Under Web Server (IIS) role add role services for: ApplicationDevelopment:ASP, ApplicationDevelopment:ISAPI Exstensions, Security:Request Filtering.

More info: http://www.iis.net/learn/application-frameworks/running-classic-asp-applications-on-iis-7-and-iis-8/classic-asp-not-installed-by-default-on-iis

Check your application's respective Application Framework Pool - it could be stopped. If it is, start it and check again.

If you're still experiencing issues you can also check out Event Viewer to find the cause of that error in order to troubleshoot more.

Download the .NET Core Hosting Bundle installer using the following link:

Current .NET Core Hosting Bundle installer (direct download)

1. Run the installer on the IIS server.
2. Restart the server or execute net stop was /y followed by net start w3svc in a command shell.

The simplest and best solution is just to use XMLRoot attribute in your class, in which you wish to deserialize.

Like:

[XmlRoot(ElementName = "YourPreferableNameHere")]
public class MyClass{
...
}

Also, use the following Assembly :

using System.Xml.Serialization;

I use it and I'm happy with it, as I have to type much less to make a new header. It worked fine for me in three platforms: Windows, Mac and Linux.

I don't have any performance information but I believe that the difference between #pragma and the include guard will be nothing comparing to the slowness of parsing the C++ grammar. That's the real problem. Try to compile the same number of files and lines with a C# compiler for example, to see the difference.

In the end, using the guard or the pragma, won't matter at all.

I was facing the same problem recently...
Heres what worked for me in MS SQL server 2017...
The primary key should be set on ID in table 2...
The columns and column properties should be the same of course between both tables. This will work the first time you run the below script. The duplicate ID in table 1, will not insert...

If you run it the second time, you will get a

Violation of PRIMARY KEY constraint error

This is the code:

Insert into Table_2
Select distinct *
from Table_1
where table_1.ID >1

The error usually gets introduced while creation of CSV. Try using Linux for saving the CSV as a TextCSV. Libre Office in Ubuntu can enforce the encoding to be UTF-8, worked for me. I wasted a lot of time trying this on Mac OS. Linux is the key. I've tested on Ubuntu.

Good Luck

Get FullName in ListBox of files (full path) list (Thomas Levesque answer modificaton, thanks Thomas):

...
        string tmpStr = "";
        foreach (var item in listBoxFiles.SelectedItems)
        {
            tmpStr += listBoxFiles.GetItemText(item) + "\n";
        }
        MessageBox.Show(tmpStr);
...

 var data= {"data": {"map":{"allowNestedValues": true,"create": "2012-12-11 15:16:13","title": "test201212110004","transitions": []}},"msg": "success","code": "0"}

o/p:

Object {data: Object, msg: "success", code: "0"}

Use JSON.stringify to convert entire data into string like below

var stringData = JSON.stringify(data);

o/p:

"{"data":{"map":{"allowNestedValues":true,"create":"2012-12-11 15:16:13","title":"test201212110004","transitions":[]}},"msg":"success","code":"0"}"

Use JSON.parse to convert entire string object into JSON Object like below

var orgdata = JSON.parse(stringData);

o/p:

Object {data: Object, msg: "success", code: "0"}

REST Over HTTPS Should be a secure method as long as API provider implements authorization a server end. In a case of web application as well what we do is accessing a web application via HTTPS and some authentication/authorization, traditionally web applications did not have security issues then Restful API would also counter security issues without problem !

Here is one without [::-1] or reversed (for learning purposes):

def reverse(text):
    new_string = []
    n = len(text)
    while (n > 0):
        new_string.append(text[n-1])
        n -= 1
    return ''.join(new_string)
print reverse("abcd")

you can use += to concatenate strings but join() is faster.

I wrote this purely SQLPlus script to dump tables to CSV in 1994.

As noted in the script comments, someone at Oracle put my script in an Oracle Support note, but without attribution.

https://github.com/jkstill/oracle-script-lib/blob/master/sql/dump.sql

The script also also builds a control file and a parameter file for SQL*LOADER

This will work.

def check(arr):
    if np.all(arr == 0):
        return True
    return False

This is a variation to the answer provided by @Metrics and edited by @Max Ghenis...

l <- sapply(iris, function(x) is.factor(x))
m <- iris[,l]

n <- sapply( m, function(x) { y <- summary(x)/length(x)
len <- length(y[y<0.005 | y>0.995])
cbind(len,t(y))} )

drop_cols_df <- data.frame(var = names(l[l]), 
                           status = ifelse(as.vector(t(n[1,]))==0,"NODROP","DROP" ),
                           level1 = as.vector(t(n[2,])),
                           level2 = as.vector(t(n[3,])))

Here, after identifying factor variables, the second sapply computes what percent of records belong to each level / category of the variable. Then it identifies number of levels over 99.5% or below 0.5% incidence rate (my arbitrary thresholds).

It then goes on to return the number of valid levels and the incidence rate of each level in each categorical variable.

Variables with zero levels crossing the thresholds should not be dropped, while the other should be dropped from the linear model.

The last data frame makes viewing the results easy. It's hard coded for this data set since all factor variables are binomial. This data frame can be made generic easily enough.

I don't agree with the way that Bootstrap uses fade in (as seen in their documentation - http://v4-alpha.getbootstrap.com/components/alerts/), and my suggestion is to avoid the class names fade and in, and to avoid that pattern in general (which is currently seen in the top-rated answer to this question).

(1) The semantics are wrong - transitions are temporary, but the class names live on. So why should we name our classes fade and fade in? It should be faded and faded-in, so that when developers read the markup, it's clear that those elements were faded or faded-in. The Bootstrap team has already done away with hide for hidden, why is fade any different?

(2) Using 2 classes fade and in for a single transition pollutes the class space. And, it's not clear that fade and in are associated with one another. The in class looks like a completely independent class, like alert and alert-success.

The best solution is to use faded when the element has been faded out, and to replace that class with faded-in when the element has been faded in.

Alert Faded

So to answer the question. I think the alert markup, style, and logic should be written in the following manner. Note: Feel free to replace the jQuery logic, if you're using vanilla javascript.

HTML

<div id="saveAlert" class="alert alert-success">
  <a class="close" href="#">×</a>
  <p><strong>Well done!</strong> You successfully read this alert message.</p>
</div>

CSS

.faded {
  opacity: 0;
  transition: opacity 1s;
}

JQuery

$('#saveAlert .close').on('click', function () {

  $("#saveAlert")
    .addClass('faded');

});

I have fixed this problem when calling a MVC3 Controller. I added:

Response.AddHeader("Access-Control-Allow-Origin", "*"); 

before my

return Json(model, JsonRequestBehavior.AllowGet);

And also my $.ajax was complaining that it does not accept Content-type header in my ajax call, so I commented it out as I know its JSON being passed to the Action.

Hope that helps.

Following is the way to do it;

1. Create a background image that looks like a dropdown.
2. Switch off browser appearance
3. Align the background image on the select component

  .control select {  
    border-radius: 0px;
    appearance: none;
    -webkit-appearance: none;
    -moz-appearance: none;
    background-image: url("<your image>");
    background-repeat: no-repeat;
    background-position: 100%;
    background-size: 20px;
  }

I considered giving a comment under the answer by taggon to this very question, but well, i felt it owed more explanation for those interested in details.

Uncaught TypeError: Cannot read property 'value' of undefined is strictly a JavaScript error.
(Note that value can be anything, but for this question value is 'map')

It's critical to understand that point, just so you avoid endless debugging cycles.
This error is common especially if just starting out in JavaScript (and it's libraries/frameworks).
For React, this has a lot to do with understanding the component lifecycle methods.

// Follow this example to get the context
// Ignore any complexity, focus on how 'props' are passed down to children

import React, { useEffect } from 'react'

// Main component
const ShowList = () => {
  // Similar to componentDidMount and componentDidUpdate
  useEffect(() => {// dispatch call to fetch items, populate the redux-store})

  return <div><MyItems items={movies} /></div>
}

// other component
const MyItems = props =>
  <ul>
    {props.items.map((item, i) => <li key={i}>item</li>)}
  </ul>


/**
  The above code should work fine, except for one problem.
  When compiling <ShowList/>,
  React-DOM renders <MyItems> before useEffect (or componentDid...) is called.
  And since `items={movies}`, 'props.items' is 'undefined' at that point.
  Thus the error message 'Cannot read property map of undefined'
 */

As a way to tackle this problem, @taggon gave a solution (see first anwser or link).

Solution: Set an initial/default value.
In our example, we can avoid items being 'undefined' by declaring a default value of an empty array.

Why? This allows React-DOM to render an empty list initially.
And when the useEffect or componentDid... method is executed, the component is re-rendered with a populated list of items.

// Let's update our 'other' component
// destructure the `items` and initialize it as an array

const MyItems = ({items = []}) =>
  <ul>
    {items.map((item, i) => <li key={i}>item</li>)}
  </ul>

Swift 4:

    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let yourVC: YourVC = storyboard.instantiateViewController(withIdentifier: "YourVC") as! YourVC

@PostConstruct is run ONCE in first when Bean Created. the solution is create a Unused property and Do your Action in Getter method of this property and add this property to your .xhtml file like this :

<h:inputHidden  value="#{loginBean.loginStatus}"/>

and in your bean code:

public void setLoginStatus(String loginStatus) {
    this.loginStatus = loginStatus;
}

public String getLoginStatus()  {
    // Do your stuff here.
    return loginStatus;
}

The problem with your conditional is in this part sshkey_result.rc == 1, because sshkey_result does not contain rc attribute and entire conditional fails.

If you want to check if file exists check exists attribute.

Here you can read more about stat module and how to use it.

npm config edit

Opens the config file in an editor. Use the --global flag to edit the global config. now you can delete what ever the registry's you don't want and save file.

npm config list will display the list of available now.

@media print {
    .footer,

    }
}

I have faced this issue, but found an answer before finding this post :

Based on unutbu's answer, load your data...

import pandas as pd
import io

texts = ['''\
id   Name   score                    isEnrolled                       Date
111  Jack                            True              2013-05-01 12:00:00
112  Nick   1.11                     False             2013-05-12 15:05:23
     Zoe    4.12                     True                                  ''',

         '''\
id   Name   score                    isEnrolled                       Date

112  Nick   1.21                     False                                
     Zoe    4.12                     False             2013-05-01 12:00:00''']


df1 = pd.read_fwf(io.StringIO(texts[0]), widths=[5,7,25,17,20], parse_dates=[4])
df2 = pd.read_fwf(io.StringIO(texts[1]), widths=[5,7,25,17,20], parse_dates=[4])

...define your diff function...

def report_diff(x):
    return x[0] if x[0] == x[1] else '{} | {}'.format(*x)

Then you can simply use a Panel to conclude :

my_panel = pd.Panel(dict(df1=df1,df2=df2))
print my_panel.apply(report_diff, axis=0)

#          id  Name        score    isEnrolled                       Date
#0        111  Jack   nan | 2.17          True        2013-05-01 12:00:00
#1        112  Nick  1.11 | 1.21         False  2013-05-12 15:05:23 | NaT
#2  nan | nan   Zoe         4.12  True | False  NaT | 2013-05-01 12:00:00

By the way, if you're in IPython Notebook, you may like to use a colored diff function to give colors depending whether cells are different, equal or left/right null :

from IPython.display import HTML
pd.options.display.max_colwidth = 500  # You need this, otherwise pandas
#                          will limit your HTML strings to 50 characters

def report_diff(x):
    if x[0]==x[1]:
        return unicode(x[0].__str__())
    elif pd.isnull(x[0]) and pd.isnull(x[1]):
        return u'<table style="background-color:#00ff00;font-weight:bold;">'+\
            '<tr><td>%s</td></tr><tr><td>%s</td></tr></table>' % ('nan', 'nan')
    elif pd.isnull(x[0]) and ~pd.isnull(x[1]):
        return u'<table style="background-color:#ffff00;font-weight:bold;">'+\
            '<tr><td>%s</td></tr><tr><td>%s</td></tr></table>' % ('nan', x[1])
    elif ~pd.isnull(x[0]) and pd.isnull(x[1]):
        return u'<table style="background-color:#0000ff;font-weight:bold;">'+\
            '<tr><td>%s</td></tr><tr><td>%s</td></tr></table>' % (x[0],'nan')
    else:
        return u'<table style="background-color:#ff0000;font-weight:bold;">'+\
            '<tr><td>%s</td></tr><tr><td>%s</td></tr></table>' % (x[0], x[1])

HTML(my_panel.apply(report_diff, axis=0).to_html(escape=False))

To open an url in a new tab, you can use the Link tag as below:

<Link to="/yourRoute" target="_blank">
    Open YourRoute in a new tab
</Link>

It's nice to keep in mind that the <Link> element gets translated to an <a> element, and as per react-router-dom docs, you can pass any props you'd like to be on it such as title, id, className, etc.

Assuming you know the position and the length of the substring:

char *buff = "this is a test string";
printf("%.*s", 4, buff + 10);

You could achieve the same thing by copying the substring to another memory destination, but it's not reasonable since you already have it in memory.

This is a good example of avoiding unnecessary copying by using pointers.

class Globals {
   static String ouch = "I'm global.."
}

println Globals.ouch

this is the DOM element on which the event was hooked. this.id is its ID. No need to wrap it in a jQuery instance to get it, the id property reflects the attribute reliably on all browsers.

$("select").change(function() {    
    alert("Changed: " + this.id);
}

Live example

You're not doing this in your code sample, but if you were watching a container with several form elements, that would give you the ID of the container. If you want the ID of the element that triggered the event, you could get that from the event object's target property:

$("#container").change(function(event) {
    alert("Field " + event.target.id + " changed");
});

Live example

(jQuery ensures that the change event bubbles, even on IE where it doesn't natively.)

Your error indicates that the operation is being cancelled for some reason. I'd need more details to understand why. But I think the bigger issue may be that since your endpoint https://host.com/a/path is bogus, there is no real server response to report, and hence you're seeing nil.

If you hit up a valid endpoint that serves up a proper response, you should see a non-nil value for res (using the techniques Sam mentions) in the form of a NSURLHTTPResponse object with properties like statusCode, etc.

Also, just to be clear, error is of type NSError. It tells you why the network request failed. The status code of the failure on the server side is actually a part of the response.

Hope that helps answer your main question.

I ran into the same problem on VS 2010, after checking publish output, event logs, turning on and checking visual studio logs etc I then decided to remove the web publish (via add/remove) which I believe had been recently updated to v1.0.30810.0. This resolved the problem.

I had the same problem. You can list the regex matches in a new tab, every match in new line in PSPad Editor, which is very similar as Notepad++.

Hit Ctrl + F to search, check the regexp opion, put the regexp and click on List.

It should be:

ClientThread hey = clients.get(clients.size() - 1);
clients.remove(hey);

Or you can do

clients.remove(clients.size() - 1);

The minus ones are because size() returns the number of elements, but the ArrayList's first element's index is 0 and not 1.

This is how I organized my application's static resources.

Using Concat on the group by will work

SELECT clients.id, clients.name, portfolios.id, SUM ( portfolios.portfolio + portfolios.cash ) AS total
FROM clients, portfolios
WHERE clients.id = portfolios.client_id
GROUP BY CONCAT(portfolios.id, "-", clients.id)
ORDER BY total DESC
LIMIT 30

Andy Buchanan, as far as sticking to C++ goes, I liked yours, but I have a few mods:

template <typename ElemT>
struct HexTo {
    ElemT value;
    operator ElemT() const {return value;}
    friend std::istream& operator>>(std::istream& in, HexTo& out) {
        in >> std::hex >> out.value;
        return in;
    }
};

Used like

uint32_t value = boost::lexical_cast<HexTo<uint32_t> >("0x2a");

That way you don't need one impl per int type.

I wanted to suggest something like Michael Shimmin's but without hardcoding things like the element, or the CSS that is applied to it.

I'm only using jQuery for add/remove class, if you don't want to use jquery, you just need a replacement for add/removeClass

--Javascript

function highlight(el, durationMs) { 
  el = $(el);
  el.addClass('highlighted');
  setTimeout(function() {
    el.removeClass('highlighted')
  }, durationMs || 1000);
}

highlight(document.getElementById('tries'));

--CSS

#tries {
    border: 1px solid gray;
}

#tries.highlighted {
    border: 3px solid red;
}

For future searchers, if none of the above worked, for me, python was trying to open a folder as a file.

Summary:

=INDEX( FILTER( G2:G , NOT(ISBLANK(G2:G))) , COUNTA(G2:G) )

Details:

I've looked through and tried several answers, and here's what I've found: The simplest solution (see Dohmoose' answer) works if there are no blanks:

=INDEX(G2:G; COUNT(G2:G))

If you have blanks, it fails.

You can handle one blank by just changing from COUNT to COUNTA (See user3280071's answer):

=INDEX(G2:G; COUNTA(G2:G))

However, this will fail for some combinations of blanks. (1 blank 1 blank 1 fails for me.)

The following code works (See Nader's answer and jason's comment):

=INDEX( FILTER( G2:G , NOT(ISBLANK(G2:G))) , ROWS( FILTER( G2:G , NOT(ISBLANK(G2:G)) ) ) )

but it requires thinking about whether you want to use COLUMNS or ROWS for a given range.

However, if COLUMNS is replaced with COUNT I seem to get a reliable, blank-proof implementation of LAST:

=INDEX( FILTER( G2:G , NOT(ISBLANK(G2:G))) , COUNT( FILTER( G2:G , NOT(ISBLANK(G2:G)) ) ) ) 

And since COUNTA has the filter built in, we can simplify further using

=INDEX( FILTER( G2:G , NOT(ISBLANK(G2:G))) , COUNTA(G2:G) )

This is somewhat simple, and correct. And you don't have to worry about whether to count rows or columns. And unlike script solutions, it automatically updates with changes to the spreadsheet.

And if you want to get the last value in a row, just change the data range:

=INDEX( FILTER( A2:2 , NOT(ISBLANK(A2:2))) , COUNTA(A2:2) )

you can use log4net.Filter.LevelMatchFilter. other options can be found at log4net tutorial - filters

in ur appender section add

<filter type="log4net.Filter.LevelMatchFilter">
    <levelToMatch value="Info" />
    <acceptOnMatch value="true" />
</filter>

the accept on match default is true so u can leave it out but if u set it to false u can filter out log4net filters

Here you go.

$('#timePicker').datetimepicker({
   // dateFormat: 'dd-mm-yy',
   format:'DD/MM/YYYY HH:mm:ss',
    minDate: getFormattedDate(new Date())
});

function getFormattedDate(date) {
    var day = date.getDate();
    var month = date.getMonth() + 1;
    var year = date.getFullYear().toString().slice(2);
    return day + '-' + month + '-' + year;
}

You need to pass datepicker() the date formatted correctly.

Try adding 2 spaces (or a backslash \) after the first line:

[Name of link](url)
My line of text\

Visually:

[Name of link](url)<space><space>
My line of text\

Output:

<p><a href="url">Name of link</a><br>
My line of text<br></p>

Use array_values(array_unique($array));

array_unique: for unique array array_values: for reindexing

As mentioned in other answers, you'll always get the QuotaExceededError in Safari Private Browser Mode on both iOS and OS X when localStorage.setItem (or sessionStorage.setItem) is called.

One solution is to do a try/catch or Modernizr check in each instance of using setItem.

However if you want a shim that simply globally stops this error being thrown, to prevent the rest of your JavaScript from breaking, you can use this:

https://gist.github.com/philfreo/68ea3cd980d72383c951

// Safari, in Private Browsing Mode, looks like it supports localStorage but all calls to setItem
// throw QuotaExceededError. We're going to detect this and just silently drop any calls to setItem
// to avoid the entire page breaking, without having to do a check at each usage of Storage.
if (typeof localStorage === 'object') {
    try {
        localStorage.setItem('localStorage', 1);
        localStorage.removeItem('localStorage');
    } catch (e) {
        Storage.prototype._setItem = Storage.prototype.setItem;
        Storage.prototype.setItem = function() {};
        alert('Your web browser does not support storing settings locally. In Safari, the most common cause of this is using "Private Browsing Mode". Some settings may not save or some features may not work properly for you.');
    }
}

Try to generate the proxy class via SvcUtil.exe with command

Syntax:

svcutil.exe /language:<type> /out:<name>.cs /config:<name>.config http://<host address>:<port>

Example:

svcutil.exe /language:cs /out:generatedProxy.cs /config:app.config http://localhost:8000/ServiceSamples/myService1

To check if service is available try in your IE URL from example upon without myService1 postfix

You can create the headers on the fly (no need to specify delimiter when the delimiter is a comma):

Thanks to Dart's factory constructors, it's easy to build a singleton:

class Singleton {
  static final Singleton _singleton = Singleton._internal();

  factory Singleton() {
    return _singleton;
  }

  Singleton._internal();
}

You can construct it like this

main() {
  var s1 = Singleton();
  var s2 = Singleton();
  print(identical(s1, s2));  // true
  print(s1 == s2);           // true
}

As Jake points out, TARGET_IPHONE_SIMULATOR is a subset of TARGET_OS_IPHONE.

Also, TARGET_OS_IPHONE is a subset of TARGET_OS_MAC.

So a better approach might be:

#ifdef _WIN64
   //define something for Windows (64-bit)
#elif _WIN32
   //define something for Windows (32-bit)
#elif __APPLE__
    #include "TargetConditionals.h"
    #if TARGET_OS_IPHONE && TARGET_IPHONE_SIMULATOR
        // define something for simulator   
    #elif TARGET_OS_IPHONE
        // define something for iphone  
    #else
        #define TARGET_OS_OSX 1
        // define something for OSX
    #endif
#elif __linux
    // linux
#elif __unix // all unices not caught above
    // Unix
#elif __posix
    // POSIX
#endif

I have had issues in the past when attempting to perform a POST (not sure if that is exactly what you are doing, but I recall when passing an array in, traditional must be set to true.

 var arrayOfValues = new Array();

 //Populate arrayOfValues 
 $.ajax({ 
      type: "POST",
      url: "<%= Url.Action("MyAction","Controller")%>",
      traditional: true,
      data: { 'arrayOfValues': arrayOfValues }              
 });

I don't know Sonar, but I suspect it's looking for a private constructor:

private FilePathHelper() {
    // No-op; won't be called
}

Otherwise the Java compiler will provide a public parameterless constructor, which you really don't want.

(You should also make the class final, although other classes wouldn't be able to extend it anyway due to it only having a private constructor.)

Just to add that if your truth value can vary, for instance if it is an input from different programming languages or from different types, a more robust method would be:

flag = value in ['True','true',1,'T','t','1'] # this can be as long as you want to support

And a more performant variant would be (set lookup is O(1)):

TRUTHS = set(['True','true',1,'T','t','1'])
flag = value in truths

Some more detail for completeness in case it helps someone...

Note that the most common reason for this exception these days is attempting to load a 32 bit-specific (/platform:x86) DLL into a process that is 64 bit or vice versa (viz. load a 64 bit-specific (/platform:x64) DLL into a process that is 32 bit). If your platform is non-specific (/platform:AnyCpu), this won't arise (assuming no referenced dependencies are of the wrong bitness).

In other words, running:

%windir%\Microsoft.NET\Framework\v2.0.50727\installutil.exe

or:

%windir%\Microsoft.NET\Framework64\v2.0.50727\installutil.exe

will not work (substitute in other framework versions: v1.1.4322 (32-bit only, so this issue doesn't arise) and v4.0.30319 as desired in the above).

Obviously, as covered in the other answer, one will also need the .NET version number of the installutil you are running to be >= (preferably =) that of the EXE/DLL file you are running the installer of.

Finally, note that in Visual Studio 2010, the tooling will default to generating x86 binaries (rather than Any CPU as previously).

Complete details of System.BadImageFormatException (saying the only cause is mismatched bittedness is really a gross oversimplification!).

Another reason for a BadImageFormatException under an x64 installer is that in Visual Studio 2010, the default .vdproj Install Project type generates a 32-bit InstallUtilLib shim, even on an x64 system (Search for "64-bit managed custom actions throw a System.BadImageFormatException exception" on the page).

Assuming you have a Z: drive mapped:

Get-ChildItem -Path "Z:" -Recurse | Where-Object { !$PsIsContainer -and [System.IO.Path]::GetFileNameWithoutExtension($_.Name) -eq "hosts" }

You cannot mention multiple column names with commas using ADD COLUMN. You need to mention ADD COLUMN every time you define a new column.

The command clause does work as @Karthik says above.

As a simple example, the following service will have a -inMemory added to its ENTRYPOINT when docker-compose up is run.

version: '2'
services:
  local-dynamo:
    build: local-dynamo
    image: spud/dynamo
    command: -inMemory

The answer was very funny for me and my team, and worked like a charm

• In the Interface Builder, Just move the tableview under another view in the view hierarchy.

REASON:

We observed that this happens only for the First View in the View Hierarchy, if this first view is a UITableView. So, all other similar UITableViews do not have this annoying section, except the first. We Tried moving the UITableView out of the first place in the view hierarchy, and everything was working as expected.

On Windows you can query the precise state of any port on any network-adapter using: GetExtendedTcpTable

You can filter it to only those related to your process, etc and do as you wish periodically monitoring as needed. This is "an alternative" approach.

You could also duplicate the socket handle and set up an IOCP/Overlapped i/o wait on the socket and monitor it that way as well.

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).

In Spring there is a dedicated utility called ReflectionTestUtils for this purpose. Take the specific instance and inject into the the field.

@Spy
..
@Mock
..

@InjectMock
Foo foo;

@BeforeEach
void _before(){
   ReflectionTestUtils.setField(foo,"bar", new BarImpl());// `bar` is private field
}

Before you can add files in an unversioned directory, you have to add the directory itself to the versioning:

svn add directory_name

will add the directory directory_name and all sub-directories: http://svnbook.red-bean.com/en/1.8/svn.ref.svn.c.add.html

I faced the similar problem in no reason, i think it was caused by IDE(android studio). I have tried all of above solutions but not worked. Finally, in my own situation, i solved this problem by the following actions: - Close the current project and remove it from the list of projects in android studio ,and reopen it by Open an existing Android Studio project, then it may be worked. I hope that my experience will be useful for you.

Others have posted some ways that you might be able to "coax" the Python interpreter into freeing the memory (or otherwise avoid having memory problems). Chances are you should try their ideas out first. However, I feel it important to give you a direct answer to your question.

There isn't really any way to directly tell Python to free memory. The fact of that matter is that if you want that low a level of control, you're going to have to write an extension in C or C++.

That said, there are some tools to help with this:

• cython
• swig
• boost python

Use execute_script, here's a python example:

from selenium import webdriver
driver = webdriver.Firefox()
driver.get("http://stackoverflow.com/questions/7794087/running-javascript-in-selenium-using-python") 
driver.execute_script("document.getElementsByClassName('comment-user')[0].click()")

if (myString != null && !myString.isEmpty()) {
  // doSomething
}

As further comment, you should be aware of this term in the equals contract:

From Object.equals(Object):

For any non-null reference value x, x.equals(null) should return false.

The way to compare with null is to use x == null and x != null.

Moreover, x.field and x.method() throws NullPointerException if x == null.

sqsh (http://www.sqsh.org/) + freetds (http://www.freetds.org)

sqsh was primarily an isql replacement for Sybase SQL Server (now ASE) but it works just fine for connecting to SQL Server (provided you use freetds).

To compile, simply point $SYBASE to freetds install and it should work from there. I use it on my Mac all day.

The best part of sqsh are the advanced features, such as dead simple server linking (no need to set up linked servers in SQL Server), flow control and looping (no more concatenating strings and executing dynamic SQL), and invisible bulk copy/load.

Anyone who uses any other command line tool is simply crazy! :)

Using color function to print text with colors

Code:

enum Color {

    RED("\033[0;31m"),      // RED
    GREEN("\033[0;32m"),    // GREEN
    YELLOW("\033[0;33m"),   // YELLOW
    BLUE("\033[0;34m"),     // BLUE
    MAGENTA("\033[0;35m"),  // MAGENTA
    CYAN("\033[0;36m"),     // CYAN

    private final String code

    Color(String code) {
        this.code = code;
    }

    @Override
    String toString() {
        return code
    }
}

def color = { color, txt ->
    def RESET_COLOR = "\033[0m"
    return "${color}${txt}${RESET_COLOR}"
}

Usage:

test {
    println color(Color.CYAN, 'testing')
}

If you want to procces an audio block by block, some of the given solutions are quite awful in the sense that they imply loading the whole audio into memory producing many cache misses and slowing down your program. python-wavefile provides some pythonic constructs to do NumPy block-by-block processing using efficient and transparent block management by means of generators. Other pythonic niceties are context manager for files, metadata as properties... and if you want the whole file interface, because you are developing a quick prototype and you don't care about efficency, the whole file interface is still there.

A simple example of processing would be:

import sys
from wavefile import WaveReader, WaveWriter

with WaveReader(sys.argv[1]) as r :
    with WaveWriter(
            'output.wav',
            channels=r.channels,
            samplerate=r.samplerate,
            ) as w :

        # Just to set the metadata
        w.metadata.title = r.metadata.title + " II"
        w.metadata.artist = r.metadata.artist

        # This is the prodessing loop
        for data in r.read_iter(size=512) :
            data[1] *= .8     # lower volume on the second channel
            w.write(data)

The example reuses the same block to read the whole file, even in the case of the last block that usually is less than the required size. In this case you get an slice of the block. So trust the returned block length instead of using a hardcoded 512 size for any further processing.

First, you have to add a ListView, an EditText and a button into your activity_main.xml.

Now, in your ActivityMain:

private EditText editTxt;
private Button btn;
private ListView list;
private ArrayAdapter<String> adapter;
private ArrayList<String> arrayList;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    editTxt = (EditText) findViewById(R.id.editText);
    btn = (Button) findViewById(R.id.button);
    list = (ListView) findViewById(R.id.listView);
    arrayList = new ArrayList<String>();

    // Adapter: You need three parameters 'the context, id of the layout (it will be where the data is shown),
    // and the array that contains the data
    adapter = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_spinner_item, arrayList);

    // Here, you set the data in your ListView
    list.setAdapter(adapter);

    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            // this line adds the data of your EditText and puts in your array
            arrayList.add(editTxt.getText().toString());
            // next thing you have to do is check if your adapter has changed
            adapter.notifyDataSetChanged();
        }
    });
}

This works for me, I hope I helped you

If you're trying to create a web service to serve data over JSON to a web page, consider using the ASP.NET Ajax toolkit:

http://www.asp.net/learn/ajax/tutorial-05-cs.aspx

It will automatically convert your objects served over a webservice to json, and create the proxy class that you can use to connect to it.

json_decode will return the same array that was originally encoded. For instanse, if you

$array = json_decode($json, true);
echo $array['countryId'];

OR

$obj= json_decode($json);

echo $obj->countryId;

These both will echo 84. I think json_encode and json_decode function names are self-explanatory...

You first need to uninstall the ruby installed by Ubuntu with something like sudo apt-get remove ruby.

Then reinstall ruby using rbenv and ruby-build according to their docs:

cd $HOME
sudo apt-get update 
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev

git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL

git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL

rbenv install 2.3.1
rbenv global 2.3.1
ruby -v

The last step is to install Bundler:

gem install bundler
rbenv rehash

Then enjoy!

No one seems to be talking about performance so I tested the two most popular answers on a sample database from Mysql. The table has 2.8M rows with structure

CREATE TABLE `salaries` (
  `emp_no` int(11) NOT NULL,
  `salary` int(11) NOT NULL,
  `from_date` date NOT NULL,
  `to_date` date NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

ALTER TABLE `salaries`
  ADD PRIMARY KEY (`emp_no`,`from_date`);

Here are the tests performed and results

SELECT * FROM `salaries` WHERE YEAR(from_date) = 1992 AND MONTH(from_date) = 6
12339 results
-----------------
11.5 ms 
12.1 ms
09.5 ms
07.5 ms
10.2 ms

My Conclusions

1. BETWEEN was slightly better on both indexed and unindexed column.
2. The unindexed column was marginally slower than the indexed column.

If you're on Ubuntu and you want to install the pre-packaged perl module (for example, geo::ipfree) try this:

    $ apt-cache search perl geo::ipfree
    libgeo-ipfree-perl - A look up country of ip address Perl module

    $ sudo apt-get install libgeo-ipfree-perl

Just found a quick and simple solution to discover type of a variable.

ES6

export const isType = (type, val) => val.constructor.name.toLowerCase() === type.toLowerCase();

ES5

function isType(type, val) {
  return val.constructor.name.toLowerCase() === type.toLowerCase();
}

Examples:

isType('array', [])
true
isType('array', {})
false
isType('string', '')
true
isType('string', 1)
false
isType('number', '')
false
isType('number', 1)
true
isType('boolean', 1)
false
isType('boolean', true)
true

EDIT

Improvment to prevent 'undefined' and 'null' values:

ES6

export const isType = (type, val) => !!(val.constructor && val.constructor.name.toLowerCase() === type.toLowerCase());

ES5

function isType(type, val) {
  return !!(val.constructor && val.constructor.name.toLowerCase() === type.toLowerCase());
}

I make a link. A link is a link. A link navigates to another page. That is what links are for and everybody understands that. So Method 3 is the only correct method in my book.

I wouldn't want my link to look like a button at all, and when I do, I still think functionality is more important than looks.

Buttons are less accessible, not only due to the need of Javascript, but also because tools for the visually impaired may not understand this Javascript enhanced button well.

Method 4 would work as well, but it is more a trick than a real functionality. You abuse a form to post 'nothing' to this other page. It's not clean.

I felt the need to continue to refine, so in MySQL:

Current timestamp in milliseconds:

floor(unix_timestamp(current_timestamp(3)) * 1000)

Timestamp in milliseconds from given datetime(3):

floor(unix_timestamp("2015-04-27 15:14:55.692") * 1000)

Convert timestamp in milliseconds to datetime(3):

from_unixtime(1430146422456 / 1000)

Convert datetime(3) to timestamp in milliseconds:

floor(unix_timestamp("2015-04-27 14:53:42.456") * 1000)

/// <summary>
/// Method return a read-only collection of the names of the constants in specified enum
/// </summary>
/// <returns></returns>
public static ReadOnlyCollection<string> GetNames()
{
    return Enum.GetNames(typeof(T)).Cast<string>().ToList().AsReadOnly();   
}

where T is a type of Enumeration; Add this:

using System.Collections.ObjectModel; 

The good, clean, fast, easy and readable ways is:

• generate equality members (Equals() and GetHashCode()) method for the current type. Tools like ReSharper not only creates the methods, but also generates the necessary code for an equality check and/or for calculating hash code. The generated code will be more optimal than Tuple realization.
• just make a simple key class derived from a tuple.

add something similar like this:

public sealed class myKey : Tuple<TypeA, TypeB, TypeC>
{
    public myKey(TypeA dataA, TypeB dataB, TypeC dataC) : base (dataA, dataB, dataC) { }

    public TypeA DataA => Item1; 

    public TypeB DataB => Item2;

    public TypeC DataC => Item3;
}

So you can use it with dictionary:

var myDictinaryData = new Dictionary<myKey, string>()
{
    {new myKey(1, 2, 3), "data123"},
    {new myKey(4, 5, 6), "data456"},
    {new myKey(7, 8, 9), "data789"}
};

• You also can use it in contracts
• as a key for join or groupings in linq
• going this way you never ever mistype order of Item1, Item2, Item3 ...
• you no need to remember or look into to code to understand where to go to get something
• no need to override IStructuralEquatable, IStructuralComparable, IComparable, ITuple they all alredy here

This usually means that something is trying to access the @property "givenName".

If you were doing something with Interface Builder(IB), the usual cause is that you either:

1. deleted that property from the class, but haven't deleted the hookups in IB yet
2. OR: you have a File's Owner object set to the wrong class (check the properties - different depending which version of xcode you're using
   • to find the Class Name its set as. You probably copy/pasted a NIB file, and didn't change this field in the NIB), and you've hooked up an outlet for that class, but your actual File's Owner is something different

Change the

private static final long serialVersionUID = 1L;

to any other value like

private static final long serialVersionUID = 102831973239L;

also you can generate it automatically in eclipse.

It is because each servlet in a app has a unique id.and tomcat causes problem with two servlets having same id...

You can pass a regular expression to the text parameter of findAll, like so:

import BeautifulSoup
import re

columns = soup.findAll('td', text = re.compile('your regex here'), attrs = {'class' : 'pos'})

This action is not bound to a key by default, to bind it do this:

1. File > Preferences > Keyboard Shortcuts (Ctrl+K, Ctrl+S)
2. Search for "find folder"
3. Press the + icon on the left of "filesExplorer.findInFolder" search result
4. Enter your desired key combination

see: https://developer.mozilla.org/en-US/docs/Web/CSS/cursor

so you need to add: cursor:pointer;

In your case use:

#more {
  background:none;
  border:none;
  color:#FFF;
  font-family:Verdana, Geneva, sans-serif;
  cursor:pointer;
}

This will apply the curser to the element with the ID "more" (can be only used once). So in your HTML use

<input type="button" id="more" />

If you want to apply this to more than one button then you have more than one possibility:

using CLASS

.more {
  background:none;
  border:none;
  color:#FFF;
  font-family:Verdana, Geneva, sans-serif;
  cursor:pointer;
}

and in your HTML use

<input type="button" class="more" value="first" />
<input type="button" class="more" value="second" />

or apply to a html context:

input[type=button] {
  background:none;
  border:none;
  color:#FFF;
  font-family:Verdana, Geneva, sans-serif;
  cursor:pointer;
}

and in your HTML use

<input type="button" value="first" />
<input type="button" value="second" />

Update:

This linked answer describes a cleaner, simpler way of doing the same thing with C# syntax.

Original post

This is Microsoft's recommended way to handle WCF client calls:

For more detail see: Expected Exceptions

try
{
    ...
    double result = client.Add(value1, value2);
    ...
    client.Close();
}
catch (TimeoutException exception)
{
    Console.WriteLine("Got {0}", exception.GetType());
    client.Abort();
}
catch (CommunicationException exception)
{
    Console.WriteLine("Got {0}", exception.GetType());
    client.Abort();
}

Additional information

So many people seem to be asking this question on WCF that Microsoft even created a dedicated sample to demonstrate how to handle exceptions:

c:\WF_WCF_Samples\WCF\Basic\Client\ExpectedExceptions\CS\client

Download the sample: C# or VB

Considering that there are so many issues involving the using statement, (heated?) Internal discussions and threads on this issue, I'm not going to waste my time trying to become a code cowboy and find a cleaner way. I'll just suck it up, and implement WCF clients this verbose (yet trusted) way for my server applications.

What about to use replaceAll java.lang.String method:

    String str = "qwerty-1qwerty-2 455 f0gfg 4";      
    str = str.replaceAll("[^-?0-9]+", " "); 
    System.out.println(Arrays.asList(str.trim().split(" ")));

Output:

[-1, -2, 455, 0, 4]

Description

[^-?0-9]+

• [ and ] delimites a set of characters to be single matched, i.e., only one time in any order
• ^ Special identifier used in the beginning of the set, used to indicate to match all characters not present in the delimited set, instead of all characters present in the set.
• + Between one and unlimited times, as many times as possible, giving back as needed
• -? One of the characters “-” and “?”
• 0-9 A character in the range between “0” and “9”

ggplot2 and scales packages can do that:

y <- c(12, 20)/100
x <- c(1, 2)

library(ggplot2)
library(scales)
myplot <- qplot(as.factor(x), y, geom="bar")
myplot + scale_y_continuous(labels=percent)

It seems like the stat() option has been taken off, causing the error message. Try this:

library(scales)

myplot <- ggplot(mtcars, aes(factor(cyl))) + 
          geom_bar(aes(y = (..count..)/sum(..count..))) + 
          scale_y_continuous(labels=percent)

myplot

I prefer the JPA2 EntityManager API over SessionFactory, because it feels more modern. One simple example:

JPA:

@PersistenceContext
EntityManager entityManager;

public List<MyEntity> findSomeApples() {
  return entityManager
     .createQuery("from MyEntity where apples=7", MyEntity.class)
     .getResultList();
}

SessionFactory:

@Autowired
SessionFactory sessionFactory;

public List<MyEntity> findSomeApples() {
  Session session = sessionFactory.getCurrentSession();
  List<?> result = session.createQuery("from MyEntity where apples=7")
      .list();
  @SuppressWarnings("unchecked")
  List<MyEntity> resultCasted = (List<MyEntity>) result;
  return resultCasted;
}

I think it's clear that the first one looks cleaner and is also easier to test because EntityManager can be easily mocked.

Vector was part of 1.0 -- the original implementation had two drawbacks:

1. Naming: vectors are really just lists which can be accessed as arrays, so it should have been called ArrayList (which is the Java 1.2 Collections replacement for Vector).

2. Concurrency: All of the get(), set() methods are synchronized, so you can't have fine grained control over synchronization.

There is not much difference between ArrayList and Vector, but you should use ArrayList.

From the API doc.

As of the Java 2 platform v1.2, this class was retrofitted to implement the List interface, making it a member of the Java Collections Framework. Unlike the new collection implementations, Vector is synchronized.

jQuery UI has a :data() selector which can also be used. It has been around since Version 1.7.0 it seems.

You can use it like this:

Get all elements with a data-company attribute

var companyElements = $("ul:data(group) li:data(company)");

Get all elements where data-company equals Microsoft

var microsoft = $("ul:data(group) li:data(company)")
                    .filter(function () {
                        return $(this).data("company") == "Microsoft";
                    });

Get all elements where data-company does not equal Microsoft

var notMicrosoft = $("ul:data(group) li:data(company)")
                       .filter(function () {
                           return $(this).data("company") != "Microsoft";
                       });

etc...

One caveat of the new :data() selector is that you must set the data value by code for it to be selected. This means that for the above to work, defining the data in HTML is not enough. You must first do this:

$("li").first().data("company", "Microsoft");

This is fine for single page applications where you are likely to use $(...).data("datakey", "value") in this or similar ways.

The issue with my designer was 32 vs 64 bit issue. I could add the control to tool box after following the instructions in Cannot add Controls from 64-bit Assemblies to the Toolbox or Use in Designers Within the Visual Studio IDE MS KB article.

When I align elements in center I use the bootstrap class text-center:

<div class="text-center">Centered content goes here</div>

You can use the util library that comes with nodejs to get a promise from the exec command and can use that output as you need. Use restructuring to store the stdout and stderr in variables.

const util = require('util');
const exec = util.promisify(require('child_process').exec);

async function lsExample() {
  const {
    stdout,
    stderr
  } = await exec('ls');
  console.log('stdout:', stdout);
  console.error('stderr:', stderr);
}
lsExample();

Quick way to print something is:

select '** Place your mesage here' AS '** DEBUG:';

All the 3 first ways are identical. You have make sure that if t is a matrix you add . before using multiplication or the power.

for matrix:

t= [1 2 3;2 3 4;3 4 5];
tp=t.*t;
x=exp(-(t.^2));
y=exp(-(t.*t));
z=exp(-(tp));

gives the results:

x =

0.3679    0.0183    0.0001
0.0183    0.0001    0.0000
0.0001    0.0000    0.0000

y =

0.3679    0.0183    0.0001
0.0183    0.0001    0.0000
0.0001    0.0000    0.0000

z=

0.3679    0.0183    0.0001
0.0183    0.0001    0.0000
0.0001    0.0000    0.0000

And using a scalar:

p=3;
pp=p^2;
x=exp(-(p^2));
y=exp(-(p*p));
z=exp(-pp);

gives the results:

x =

1.2341e-004

y =

1.2341e-004

z =

1.2341e-004

It normally happens when you are download projects from the github. normally dark sdk contains inside flutter.

you can solve this issue following these few steps

1. go to the setting using (Ctrl + Shift + s)
2. go the the Languages & Framework
3. go to Dart
4. Enable Dark support for the project
5. Change the dark sdk path C:\flutter\bin\cache\dart-sdk
6. Apply

I have a raspberry pi, and I am using python web server (using Flask). I have tried everything above, the only solution is to close the terminal(shell) and open it again. Or restart the raspberry pi, because nothing stops that webserver...

I realize this is quite late, but I needed something like this so I whipped up a quick and dirty method to do this.

+ (UIImage *) image:(UIImage *)image withAlpha:(CGFloat)alpha{

    // Create a pixel buffer in an easy to use format
    CGImageRef imageRef = [image CGImage];
    NSUInteger width = CGImageGetWidth(imageRef);
    NSUInteger height = CGImageGetHeight(imageRef);
    CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();

    UInt8 * m_PixelBuf = malloc(sizeof(UInt8) * height * width * 4);

    NSUInteger bytesPerPixel = 4;
    NSUInteger bytesPerRow = bytesPerPixel * width;
    NSUInteger bitsPerComponent = 8;
    CGContextRef context = CGBitmapContextCreate(m_PixelBuf, width, height,
                                                 bitsPerComponent, bytesPerRow, colorSpace,
                                                 kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big);

    CGContextDrawImage(context, CGRectMake(0, 0, width, height), imageRef);
    CGContextRelease(context);

    //alter the alpha
    int length = height * width * 4;
    for (int i=0; i<length; i+=4)
    {
        m_PixelBuf[i+3] =  255*alpha;
    }


    //create a new image
    CGContextRef ctx = CGBitmapContextCreate(m_PixelBuf, width, height,
                                                 bitsPerComponent, bytesPerRow, colorSpace,
                                                 kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big);

    CGImageRef newImgRef = CGBitmapContextCreateImage(ctx);  
    CGColorSpaceRelease(colorSpace);
    CGContextRelease(ctx);  
    free(m_PixelBuf);

    UIImage *finalImage = [UIImage imageWithCGImage:newImgRef];
    CGImageRelease(newImgRef);  

    return finalImage;
}

try to implement with javascript this:

<div id="mydiv" onclick="myhref('http://web.com');" >some stuff </div>
<script type="text/javascript">
    function myhref(web){
      window.location.href = web;}
</script>

Strings are immutable, meaning their contents cannot change. When you call replace(this,that) you end up with a totally new String. If you want to keep this new copy, you need to assign it to a variable. You can overwrite the old reference (a la sentence = sentence.replace(this,that) or a new reference as seen below:

public class Test{

    public static void main(String[] args) {

        String sentence = "Define, Measure, Analyze, Design and Verify";

        String replaced = sentence.replace("and", "");
        System.out.println(replaced);

    }
}

As an aside, note that I've removed the contains() check, as it is an unnecessary call here. If it didn't contain it, the replace will just fail to make any replacements. You'd only want that contains method if what you're replacing was different than the actual condition you're checking.

Changing the width of the container also fixes it rather than changing the width and height of source file.

.SvgImage img{ width:80%; }

This fixes my issue of re sizing svg . you can give any % based on your requirement.

it works for me. if you want to enable future time for choose, you have to delete maximum date. You need to to do like followings.

 btnDate.setOnClickListener(new View.OnClickListener() {
                       @Override
                       public void onClick(View v) {
                              DialogFragment newFragment = new DatePickerFragment();
                                    newFragment.show(getSupportFragmentManager(), "datePicker");
                            }
                        });

            public static class DatePickerFragment extends DialogFragment
                        implements DatePickerDialog.OnDateSetListener {

                    @Override
                    public Dialog onCreateDialog(Bundle savedInstanceState) {
                        final Calendar c = Calendar.getInstance();
                        int year = c.get(Calendar.YEAR);
                        int month = c.get(Calendar.MONTH);
                        int day = c.get(Calendar.DAY_OF_MONTH);
                        DatePickerDialog dialog = new DatePickerDialog(getActivity(), this, year, month, day);
                        dialog.getDatePicker().setMaxDate(c.getTimeInMillis());
                        return  dialog;
                    }

                    public void onDateSet(DatePicker view, int year, int month, int day) {
                       btnDate.setText(ConverterDate.ConvertDate(year, month + 1, day));
                    }
                }

ls -t list files by creation time not last modified time. Use ls -ltc if you want to list files by last modified time from last to first(top to bottom). Thus to list the last n: ls -ltc | head ${n}

If you want to extend the amount of time permitted for an ASP.NET script to execute then increase the Server.ScriptTimeout value. The default is 90 seconds for .NET 1.x and 110 seconds for .NET 2.0 and later.

For example:

// Increase script timeout for current page to five minutes
Server.ScriptTimeout = 300;

This value can also be configured in your web.config file in the httpRuntime configuration element:

<!-- Increase script timeout to five minutes -->
<httpRuntime executionTimeout="300" 
  ... other configuration attributes ...
/>

Please note according to the MSDN documentation:

"This time-out applies only if the debug attribute in the compilation element is False. Therefore, if the debug attribute is True, you do not have to set this attribute to a large value in order to avoid application shutdown while you are debugging."

If you've already done this but are finding that your session is expiring then increase the ASP.NET HttpSessionState.Timeout value:

For example:

// Increase session timeout to thirty minutes
Session.Timeout = 30;

This value can also be configured in your web.config file in the sessionState configuration element:

<configuration>
  <system.web>
    <sessionState 
      mode="InProc"
      cookieless="true"
      timeout="30" />
  </system.web>
</configuration>

If your script is taking several minutes to execute and there are many concurrent users then consider changing the page to an Asynchronous Page. This will increase the scalability of your application.

The other alternative, if you have administrator access to the server, is to consider this long running operation as a candidate for implementing as a scheduled task or a windows service.

Although adding something to nodejs module is possible, it seems to be not the best way (if you try to run your code on other computer, the program will crash with the same error, obviously).

I would rather set max listeners number in your own code:

var options = {uri:headingUri, headers:headerData, maxRedirects:100};
request.setMaxListeners(0);
request.get(options, function (error, response, body) {
}

In case somebody needs to append the output and not overriding, it is possible to use "-a" or "--append" option of "tee" command :

ls 2>&1 | tee -a /tmp/ls.txt
ls 2>&1 | tee --append /tmp/ls.txt

I ran into the same problem using MySQL Workbench. According to the MySQL documentation, the DECLARE "statement declares local variables within stored programs." That apparently means it is only guaranteed to work with stored procedures/functions.

The solution for me was to simply remove the DECLARE statement, and introduce the variable in the SET statement. For your code that would mean:

-- DECLARE FOO varchar(7); 
-- DECLARE oldFOO varchar(7);

-- the @ symbol is required
SET @FOO = '138'; 
SET @oldFOO = CONCAT('0', FOO);

UPDATE mypermits SET person = FOO WHERE person = oldFOO;

This can be done in a single line without the use of library. Please check java.text.MessageFormat class.

Example

String stringWithPlaceHolder = "test String with placeholders {0} {1} {2} {3}";
String formattedStrin = java.text.MessageFormat.format(stringWithPlaceHolder, "place-holder-1", "place-holder-2", "place-holder-3", "place-holder-4");

Output will be

test String with placeholders place-holder-1 place-holder-2 place-holder-3 place-holder-4

I was looking for a similar solution, but the ones mentioned here would not work. My data had all variations of whitespace (space, newline, tab) chars and commas.

To make the column data tsv safe, I replaced all \t chars in the column data with a space, and executed python code on the commandline to generate a csv file, as shown below:

hive -e 'tab_replaced_hql_query' |  python -c 'exec("import sys;import csv;reader = csv.reader(sys.stdin, dialect=csv.excel_tab);writer = csv.writer(sys.stdout, dialect=csv.excel)\nfor row in reader: writer.writerow(row)")'

This created a perfectly valid csv. Hope this helps those who come looking for this solution.

For a lack of a better solution, I got this working for me: Assume I have 1 activity (MyActivity) and few fragments that replaces each other (only one is visible at a time).

In MyActivity, add this listener:

getSupportFragmentManager().addOnBackStackChangedListener(getListener());

(As you can see I'm using the compatibility package).

getListener implementation:

private OnBackStackChangedListener getListener()
    {
        OnBackStackChangedListener result = new OnBackStackChangedListener()
        {
            public void onBackStackChanged() 
            {                   
                FragmentManager manager = getSupportFragmentManager();

                if (manager != null)
                {
                    MyFragment currFrag = (MyFragment) manager.findFragmentById(R.id.fragmentItem);

                    currFrag.onFragmentResume();
                }                   
            }
        };

        return result;
    }

MyFragment.onFragmentResume() will be called after a "Back" is pressed. few caveats though:

1. It assumes you added all transactions to the backstack (using FragmentTransaction.addToBackStack())
2. It will be activated upon each stack change (you can store other stuff in the back stack such as animation) so you might get multiple calls for the same instance of fragment.

It is possible to download all of the UNIX commands compiled for Windows, including which from this GitHub repository: https://github.com/George-Ogden/UNIX

jQuery is just a set of helpers/libraries written in Javascript. You can still use all Javascript features, so you can call whatever functions, also from inside jQuery callbacks. So both possibilities should be okay.

image has a shape of (64,64,3).

Your input placeholder _x have a shape of (?, 64,64,3).

The problem is that you're feeding the placeholder with a value of a different shape.

You have to feed it with a value of (1, 64, 64, 3) = a batch of 1 image.

Just reshape your image value to a batch with size one.

image = array(img).reshape(1, 64,64,3)

P.S: the fact that the input placeholder accepts a batch of images, means that you can run predicions for a batch of images in parallel. You can try to read more than 1 image (N images) and than build a batch of N image, using a tensor with shape (N, 64,64,3)

This is kind of mucky, and when I say kind of mucky I may mean revolting, but supposing you can furnish your parameterised type with an empty constructor, then:

public static T GetTInstance<T>() where T: new()
{
    var constructorTypeSignature = new Type[] {typeof (object)};
    var constructorParameters = new object[] {"Create a T"};
    return (T) new T().GetType().GetConstructor(constructorTypeSignature).Invoke(constructorParameters);
}

Will effectively allow you to construct an object from a parameterised type with an argument. In this case I am assuming the constructor I want has a single argument of type object. We create a dummy instance of T using the constraint permitted empty constructor and then use reflection to get one of its other constructors.

If you are OS X 10.6/iOS 4.0 or later, you're probably better off with blocks than NSPredicate. See -[NSArray indexesOfObjectsPassingTest:] or write your own category to add a handy -select: or -filter: method (example).

Want somebody else to write that category, test it, etc.? Check out BlocksKit (array docs). And there are many more examples to be found by, say, searching for e.g. "nsarray block category select".

for whole row

insert into xyz select * from xyz2 where id="1";

for selected column

insert into xyz(t_id,v_id,f_name) select t_id,v_id,f_name from xyz2 where id="1";

Even if it is really discouraged to use merge cells in Excel (use Center Across Selection for instance if needed), the cell that "contains" the value is the one on the top left (at least, that's a way to express it).

Hence, you can get the value of merged cells in range B4:B11 in several ways:

• Range("B4").Value
• Range("B4:B11").Cells(1).Value
• Range("B4:B11").Cells(1,1).Value

You can also note that all the other cells have no value in them. While debugging, you can see that the value is empty.

Also note that Range("B4:B11").Value won't work (raises an execution error number 13 if you try to Debug.Print it) because it returns an array.

Two possible approaches.

1. If you have a foreign key, declare it as on-delete-cascade and delete the parent rows older than 30 days. All the child rows will be deleted automatically.

2. Based on your description, it looks like you know the parent rows that you want to delete and need to delete the corresponding child rows. Have you tried SQL like this?

     delete from child_table
         where parent_id in (
              select parent_id from parent_table
                   where updd_tms != (sysdate-30)
   

   -- now delete the parent table records

   delete from parent_table
   where updd_tms != (sysdate-30);
   

---- Based on your requirement, it looks like you might have to use PL/SQL. I'll see if someone can post a pure SQL solution to this (in which case that would definitely be the way to go).

declare
    v_sqlcode number;
    PRAGMA EXCEPTION_INIT(foreign_key_violated, -02291);
begin
    for v_rec in (select parent_id, child id from child_table
                         where updd_tms != (sysdate-30) ) loop

    -- delete the children
    delete from child_table where child_id = v_rec.child_id;

    -- delete the parent. If we get foreign key violation, 
    -- stop this step and continue the loop
    begin
       delete from parent_table
          where parent_id = v_rec.parent_id;
    exception
       when foreign_key_violated
         then null;
    end;
 end loop;
end;

Have you looked at angular-ui bootstrap? There's a Dialog (ui.bootstrap.dialog) directive that works quite well. You can close the dialog during the call back the angular way (per the example):

$scope.close = function(result){
  dialog.close(result);
};

Update:

The directive has since been renamed Modal.

Open below file C:\xampp\htdocs\project\common\config\params-local.php

Before your code:

<?php

return [


];

after your code:

<?php
yii::setAlias('@path1', 'localhost/foodbam/backend/web');

return [


];

You can use function: wc_get_page_id( 'cart' ) to get the ID of the page. This function will use the page setup as 'cart' page and not the slug. Meaning it will keep working also when you setup a different url for your 'cart' on the settings page. This works for all kind of Woocommerce special page, like 'checkout', 'shop' etc.

example:

if (wc_get_page_id( 'cart' ) == get_the_ID()) {
  // Do something.
}

Try to use appendChild method:

select.appendChild(option);

Oh ok - now I get it. You can ignore this one - the XML for this is just not correct - the packages-element is indeed not declared (there is no reference to a schema or whatever). I think this is a known minor bug that won't do a thing because only NuGet will use this.

See this similar question also.

It turns out I was just missing DECIMAL on the CAST() description:

DECIMAL[(M[,D])]

Converts a value to DECIMAL data type. The optional arguments M and D specify the precision (M specifies the total number of digits) and the scale (D specifies the number of digits after the decimal point) of the decimal value. The default precision is two digits after the decimal point.

Thus, the following query worked:

UPDATE table SET
latitude = CAST(old_latitude AS DECIMAL(10,6)),
longitude = CAST(old_longitude AS DECIMAL(10,6));

The extra page problem in my case was caused by table element on the page. I tried many of the solutions offered here, but to solve the problem I had to change the table css to:

table {
    width: 99%;
    height: 99%;
}

Object Oriented Programming offers:

1. Encapsulation, to
   • control mutation of internal state
   • limit coupling to internal representation
2. Subtyping, allowing:
   • substitution of compatible types (polymorphism)
   • a crude means of sharing implementation between classes (implementation inheritance)

Functional Programming, in Haskell or even in Scala, can allow substitution through more general mechanism of type classes. Mutable internal state is either discouraged or forbidden. Encapsulation of internal representation can also be achieved. See Haskell vs OOP for a good comparison.

Norman's assertion that "Adding a new kind of thing to a functional program may require editing many function definitions to add a new case." depends on how well the functional code has employed type classes. If Pattern Matching on a particular Abstract Data Type is spread throughout a codebase, you will indeed suffer from this problem, but it is perhaps a poor design to start with.

EDITED Removed reference to implicit conversions when discussing type classes. In Scala, type classes are encoded with implicit parameters, not conversions, although implicit conversions are another means to acheiving substitution of compatible types.

This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.

There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.

The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like

1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host

EDIT

Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication

Use the Integer wrapper class instead of String because it is doing the hard work for you by implementing Comparable<Integer>. Then java.util.Collections.sort(list); would do the trick.

use labelpad parameter:

pl.xlabel("...", labelpad=20)

or set it after:

ax.xaxis.labelpad = 20

This works for me:

var object = { a: 4, b: 0.5 , c: 0.35, d: 5 };
// Take all value from the object into list
var valueList = $.map(object,function(v){
     return v;
});
var max = valueList.reduce(function(a, b) { return Math.max(a, b); });
var min = valueList.reduce(function(a, b) { return Math.min(a, b); });

Put --exec arg in single quotation.

e.g. I changed "nodemon --exec yarn build-langs" to "nodemon --exec 'yarn build-langs'" and worked.

You could also look at a migrations solution. These allow you to specify your database schema in C# code, and roll your database version up and down using MSBuild.

I'm currently using DbUp, and it's been working well.

while (<>) {
print;
}

will read either from a file specified on the command line or from stdin if no file is given

If you are required this loop construction in command line, then you may use -n option:

$ perl -ne 'print;'

Here you just put code between {} from first example into '' in second

var date = new Date("enter your  date");//2018-01-17 14:58:29.013

Just one line is enough no need to do any kind of split, join, etc.:

$scope.ssdate=date.toLocaleDateString();//  mm/dd/yyyy format

I know this question has been answered a long time ago and the accepted answer will actually do the work. But there's one thing that bothers me: having to copy 2 models only to disable a validation.

Here's my suggestion:

public class InsertModel
{
    [Display(...)]
    public virtual string ID { get; set; }

    ...Other properties
}

public class UpdateModel : InsertModel
{
    [Required]
    public override string ID
    {
        get { return base.ID; }
        set { base.ID = value; }
    }
}

This way, you don't have to bother with client/server side validations, the framework will behave the way it's supposed to. Also, if you define a [Display] attribute on the base class, you don't have to redefine it in your UpdateModel.

And you can still use these classes the same way:

[HttpPost]
public ActionResult Update(UpdateModel model)
{
    ...
}

[HttpPost]
public ActionResult Insert(InsertModel model)
{
    ...
}

I tried the above solutions in Python3 but this one seems to be the only one working for me when storing objects in a dict. Basically you make a copy of your dict() and iterate over that while deleting the entries in your original dictionary.

        tmpDict = realDict.copy()
        for key, value in tmpDict.items():
            if value:
                del(realDict[key])

There is a way, but it has its limitations. You can use the FORMATMESSAGE() function. It allows you to format a string using formatting similar to the printf() function in C.

However, the biggest limitation is that it will only work with messages in the sys.messages table. Here's an article about it: microsoft_library_ms186788

It's kind of a shame there isn't an easier way to do this, because there are times when you want to format a string/varchar in the database. Hopefully you are only looking to format a string in a standard way and can use the sys.messages table.

Coincidentally, you could also use the RAISERROR() function with a very low severity, the documentation for raiseerror even mentions doing this, but the results are only printed. So you wouldn't be able to do anything with the resulting value (from what I understand).

Good luck!

You don't mention what language you want to track these in, but I found two for javascript:

http://www.cambiaresearch.com/c4/702b8cd1-e5b0-42e6-83ac-25f0306e3e25/Javascript-Char-Codes-Key-Codes.aspx

This is SUPER late and probably not relevant anymore, but if anyone stumbles upon this answer, I believe I know the cause.

So the JSON encoded string is perfectly valid with the degree symbol in it, as the other answer mentions. The problem is most likely in the character encoding that you are reading/writing with. Depending on how you are using Gson, you are probably passing it a java.io.Reader instance. Any time you are creating a Reader from an InputStream, you need to specify the character encoding, or java.nio.charset.Charset instance (it's usually best to use java.nio.charset.StandardCharsets.UTF_8). If you don't specify a Charset, Java will use your platform default encoding, which on Windows is usually CP-1252.

We also decided to use jersey as a solution. But as we are using org.JSON in most of the cases this dependency is unecessary and we felt not good.

Therefore we used the String representation to get a org.JSON object, instead of

JSONObject output = response.getEntity(JSONObject.class); 

we use it this way now:

JSONObject output = new JSONObject(response.getEntity(String.class)); 

where JSONObject comes from org.JSON and the imports could be changed from:

-import org.codehaus.jettison.json.JSONArray;
-import org.codehaus.jettison.json.JSONException;
-import org.codehaus.jettison.json.JSONObject;
+import org.json.JSONArray;
+import org.json.JSONException;
+import org.json.JSONObject;

I got the error as, "svn: Commit blocked by pre-commit hook (exit code 1) with output: Failed with exception: Lost connection to MySQL server at 'reading initial communication packet', system error: 104."

I tried 'svn commit' after 'svn cleanup'. And It works fine!.

If I let raw_input like that, no Josh or anything else. It's a variable,I think,but I don't understand her roll :-(

The raw_input function prompts you for input and returns that as a string. This certainly worked for me. You don't need idle. Just open a "DOS prompt" and run the program.

This is what it looked like for me:

C:\temp>type test.py
print "Halt!"
s = raw_input("Who Goes there? ")
print "You may pass,", s

C:\temp>python test.py
Halt!
Who Goes there? Magnus
You may pass, Magnus

I types my name and pressed [Enter] after the program had printed "Who Goes there?"

I think I got it at last by doing some manual transformations with the data before visualization:

d <- diamonds
# computing logarithm of prices
d$price <- log10(d$price)

And work out a formatter to later compute 'back' the logarithmic data:

formatBack <- function(x) 10^x 
# or with special formatter (here: "dollar")
formatBack <- function(x) paste(round(10^x, 2), "$", sep=' ') 

And draw the plot with given formatter:

m <- ggplot(d, aes(y = price, x = color))
m + geom_boxplot() + scale_y_continuous(formatter='formatBack')

Sorry to the community to bother you with a question I could have solved before! The funny part is: I was working hard to make this plot work a month ago but did not succeed. After asking here, I got it.

Anyway, thanks to @DWin for motivation!

As said before, you code will not work the way it is. A solution to that would be using a callback function, but if you think it would carry you to a 'Callback hell', you can search for "Promisses".

A possible solution using a callback function:

//DECLARE  numberofDocs OUT OF FUNCTIONS
     var  numberofDocs;
     userModel.count({}, setNumberofDocuments); //this search all DOcuments in a Collection

if you want to search the number of documents based on a query, you can do this:

 userModel.count({yourQueryGoesHere}, setNumberofDocuments);

setNumberofDocuments is a separeted function :

var setNumberofDocuments = function(err, count){ 
        if(err) return handleError(err);

        numberofDocs = count;

      };

Now you can get the number of Documents anywhere with a getFunction:

     function getNumberofDocs(){
           return numberofDocs;
        }
 var number = getNumberofDocs();

In addition , you use this asynchronous function inside a synchronous one by using a callback, example:

function calculateNumberOfDoc(someParameter, setNumberofDocuments){

       userModel.count({}, setNumberofDocuments); //this search all DOcuments in a Collection

       setNumberofDocuments(true);


} 

Hope it can help others. :)

On Windows maybe the play "run 9001" will not work. You have to change the play.bat file. See Ticket

In my case, I was quite sure it was one of my own sessions which was blocking. Therefore, it was safe to do the following:

• I found the offending session with:

  SELECT * FROM V$SESSION WHERE OSUSER='my_local_username';

  The session was inactive, but it still held the lock somehow. Note, that you may need to use some other WHERE condition in your case (e.g. try USERNAME or MACHINE fields).

• Killed the session using the ID and SERIAL# acquired above:

  alter system kill session '<id>, <serial#>';

Edited by @thermz: If none of the previous open-session queries work try this one. This query can help you to avoid syntax errors while killing sessions:

• SELECT 'ALTER SYSTEM KILL SESSION '''||SID||','||SERIAL#||''' immediate;' FROM V$SESSION WHERE OSUSER='my_local_username_on_OS'

If you are using intellij, then try restarting intellij cache

Adding to Ziav's answer (with thanks to Alexander Savin), I need to be using the old-school <a name="...">...</a> as we're using <div id="...">...</div> for another purpose in our code. I had some display issues using display: inline-block -- the first line of every <p> element was turning out to be slightly right-indented (on both Webkit and Firefox browsers). I ended up trying other display values and display: table-caption works perfectly for me.

.anchor {
  padding-top: 60px;
  margin-top: -60px;
  display: table-caption;
}

The following should work:

public static void main(String[] args)
{
    final String title = "Test Window";
    final int width = 1200;
    final int height = width / 16 * 9;

    //Creating the frame.
    JFrame frame = new JFrame(title);

    frame.setSize(width, height);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setLocationRelativeTo(null);
    frame.setResizable(false);
    frame.setVisible(true);

    //Creating the canvas.
    Canvas canvas = new Canvas();

    canvas.setSize(width, height);
    canvas.setBackground(Color.BLACK);
    canvas.setVisible(true);
    canvas.setFocusable(false);


    //Putting it all together.
    frame.add(canvas);

    canvas.createBufferStrategy(3);

    boolean running = true;

    BufferStrategy bufferStrategy;
    Graphics graphics;

    while (running) {
        bufferStrategy = canvas.getBufferStrategy();
        graphics = bufferStrategy.getDrawGraphics();
        graphics.clearRect(0, 0, width, height);

        graphics.setColor(Color.GREEN);
        graphics.drawString("This is some text placed in the top left corner.", 5, 15);

        bufferStrategy.show();
        graphics.dispose();
    }
}

Both JBoss and Tomcat are Java servlet application servers, but JBoss is a whole lot more. The substantial difference between the two is that JBoss provides a full Java Enterprise Edition (Java EE) stack, including Enterprise JavaBeans and many other technologies that are useful for developers working on enterprise Java applications.

Tomcat is much more limited. One way to think of it is that JBoss is a Java EE stack that includes a servlet container and web server, whereas Tomcat, for the most part, is a servlet container and web server.

<input [ngModel]="item.value | currency" (ngModelChange)="item.value=$event"

I would like to add one more point to the accepted answer.

If the type of your input control is not text the pipe will not work.

Keep it in mind and save your time.

"_blank" is not guaranteed to be a new tab or window. It's implemented differently per-browser.

You can, however, put anything into target. I usually just say "_tab", and every browser I know of just opens it in a new tab.

Be aware that it means it's a named target, so if you try to open 2 URLs, they will use the same tab.

I have a new response for this case: the easy way to solve this is having you jenkinsFile from source code.

Then you chose: this job have a git parameter

And and the Pipeline setup, unchecked the "Lightweight checkout" checkbox, this will perform a really git checkout on job workspace.

After, the parameter will be autopopulate by your git branch

I got same issue with

$image_base64 = base64_encode(file_get_contents($_FILES['file']['tmp_name']) );
$image = 'data:image/jpeg;base64,'.$image_base64;
$query = "insert into images(image) values('".$image."')";
mysqli_query($con,$query);

In \xampp\mysql\bin\my.ini file of phpmyadmin we get only

[mysqldump]
max_allowed_packet=110M

which is just for mysqldump -u root -p dbname . I resolved my issue by replacing above code with

max_allowed_packet=110M
[mysqldump]
max_allowed_packet=110M

For an unmanaged DLL file, you need to first check if it is a 16-bit DLL file (hopefully not). Then check the IMAGE\_FILE_HEADER.Machine field.

Someone else took the time to work this out already, so I will just repeat here:

To distinguish between a 32-bit and 64-bit PE file, you should check IMAGE_FILE_HEADER.Machine field. Based on the Microsoft PE and COFF specification below, I have listed out all the possible values for this field: http://download.microsoft.com/download/9/c/5/9c5b2167-8017-4bae-9fde-d599bac8184a/pecoff_v8.doc

IMAGE_FILE_MACHINE_UNKNOWN 0x0 The contents of this field are assumed to be applicable to any machine type

IMAGE_FILE_MACHINE_AM33 0x1d3 Matsushita AM33

IMAGE_FILE_MACHINE_AMD64 0x8664 x64

IMAGE_FILE_MACHINE_ARM 0x1c0 ARM little endian

IMAGE_FILE_MACHINE_EBC 0xebc EFI byte code

IMAGE_FILE_MACHINE_I386 0x14c Intel 386 or later processors and compatible processors

IMAGE_FILE_MACHINE_IA64 0x200 Intel Itanium processor family

IMAGE_FILE_MACHINE_M32R 0x9041 Mitsubishi M32R little endian

IMAGE_FILE_MACHINE_MIPS16 0x266 MIPS16

IMAGE_FILE_MACHINE_MIPSFPU 0x366 MIPS with FPU

IMAGE_FILE_MACHINE_MIPSFPU16 0x466 MIPS16 with FPU

IMAGE_FILE_MACHINE_POWERPC 0x1f0 Power PC little endian

IMAGE_FILE_MACHINE_POWERPCFP 0x1f1 Power PC with floating point support

IMAGE_FILE_MACHINE_R4000 0x166 MIPS little endian

IMAGE_FILE_MACHINE_SH3 0x1a2 Hitachi SH3

IMAGE_FILE_MACHINE_SH3DSP 0x1a3 Hitachi SH3 DSP

IMAGE_FILE_MACHINE_SH4 0x1a6 Hitachi SH4

IMAGE_FILE_MACHINE_SH5 0x1a8 Hitachi SH5

IMAGE_FILE_MACHINE_THUMB 0x1c2 Thumb

IMAGE_FILE_MACHINE_WCEMIPSV2 0x169 MIPS little-endian WCE v2

Yes, you may check IMAGE_FILE_MACHINE_AMD64|IMAGE_FILE_MACHINE_IA64 for 64bit and IMAGE_FILE_MACHINE_I386 for 32bit.

Here is the best approach I have found: Check existence of __len__ and __getitem__.

You may ask why? The reasons includes:

1. The popular method isinstance(obj, abc.Sequence) fails on some objects including PyTorch's Tensor because they do not implement __contains__.
2. Unfortunately, there is nothing in Python's collections.abc that checks for only __len__ and __getitem__ which I feel are minimal methods for array-like objects.
3. It works on list, tuple, ndarray, Tensor etc.

So without further ado:

def is_array_like(obj, string_is_array=False, tuple_is_array=True):
    result = hasattr(obj, "__len__") and hasattr(obj, '__getitem__') 
    if result and not string_is_array and isinstance(obj, (str, abc.ByteString)):
        result = False
    if result and not tuple_is_array and isinstance(obj, tuple):
        result = False
    return result

Note that I've added default parameters because most of the time you might want to consider strings as values, not arrays. Similarly for tuples.

You should check type of received parameters. Maybe you should use arguments array since second parameter can sometimes be 'parameters' and sometimes 'callback' and naming it parameters might be misleading.

Try using this:

If you specify ON DUPLICATE KEY UPDATE, and a row is inserted that would cause a duplicate value in a UNIQUE index orPRIMARY KEY, MySQL performs an [UPDATE`](http://dev.mysql.com/doc/refman/5.7/en/update.html) of the old row...

The ON DUPLICATE KEY UPDATE clause can contain multiple column assignments, separated by commas.

With ON DUPLICATE KEY UPDATE, the affected-rows value per row is 1 if the row is inserted as a new row, 2 if an existing row is updated, and 0 if an existing row is set to its current values. If you specify the CLIENT_FOUND_ROWS flag to mysql_real_connect() when connecting to mysqld, the affected-rows value is 1 (not 0) if an existing row is set to its current values...

This is a side note if one still can't access localhost from another devices after following through the step above. This might be due to the apache ports.conf has been configured to serve locally (127.0.0.1) and not to outside.

check the following, (for ubuntu apache2)

  $ cat /etc/apache2/ports.conf

if the following is set,

NameVirtualHost *:80  
Listen 127.0.0.1:80  

then change it back to default value

NameVirtualHost *:80  
Listen 80  

You can try like this:
yourArray.shift()

I'd say use hash, like this:

window.onload = function() {
    if(!window.location.hash) {
        window.location = window.location + '#loaded';
        window.location.reload();
    }
}

You should make a habit of looking at the documentation for stuff like this. It's very useful and will improve your skills very quickly. Here's the relevant bit when you do git help diff

   git diff [options] [--no-index] [--] <path> <path>

The two <path>s are what you need to change to the directories in question.

Webclient client = new Webclient();
string content = client.DownloadString(url);

Pass the URL of page who you want to get. You can parse the result using htmlagilitypack.

Just grep through the working directory and send the output through the xargs command:

grep -lr '<<<<<<<' . | xargs git checkout --ours

or

grep -lr '<<<<<<<' . | xargs git checkout --theirs

How this works: grep will search through every file in the current directory (the .) and subdirectories recursively (the -r flag) looking for conflict markers (the string '<<<<<<<')

the -l or --files-with-matches flag causes grep to output only the filename where the string was found. Scanning stops after first match, so each matched file is only output once.

The matched file names are then piped to xargs, a utility that breaks up the piped input stream into individual arguments for git checkout --ours or --theirs

More at this link.

Since it would be very inconvenient to have to type this every time at the command line, if you do find yourself using it a lot, it might not be a bad idea to create an alias for your shell of choice: Bash is the usual one.

This method should work through at least Git versions 2.4.x

The following code checks the referred directory in your code exists or not, if it doesn't exist in your workplace then, it creates one:

import os

if not os.path.isdir("directory_name"):
    os.mkdir("directory_name")

If you are attempting to debug from a different computer than you were originally you will get the dreaded INSTALL_FAILED_UPDATE_INCOMPATIBLE error. However, there is a way to proceed without uninstalling the app and losing your data.

To see how to transfer the debug.keystore that is required so you don't get the message "The device already has an application with the same application but a different signature. In order to proceed you will have to uninstall the existing application." (and lose your data). See Update the app in another machine with same debug.keystore in android

I tend to follow the design of JDK libraries, especially Collections and Concurrency (Joshua Bloch, Doug Lea, those guys know how to design solid APIs). Anyway, many APIs in the JDK pro-actively throws NullPointerException.

For example, the Javadoc for Map.containsKey states:

@throws NullPointerException if the key is null and this map does not permit null keys (optional).

It's perfectly valid to throw your own NPE. The convention is to include the parameter name which was null in the message of the exception.

The pattern goes:

public void someMethod(Object mustNotBeNull) {  
    if (mustNotBeNull == null) {  
        throw new NullPointerException("mustNotBeNull must not be null");  
    }  
}

Whatever you do, don't allow a bad value to get set and throw an exception later when other code attempts to use it. That makes debugging a nightmare. You should always the follow the "fail-fast" principle.

I'm assuming that you're wanting to insert a style tag versus a link tag (referencing an external CSS), so that's what the following example does:

<html>
 <head>
  <title>Example Page</title>
 </head>
 <body>
  <span>
   This is styled dynamically via JavaScript.
  </span>
 </body>
 <script type="text/javascript">
   var styleNode = document.createElement('style');
   styleNode.type = "text/css";
   // browser detection (based on prototype.js)
   if(!!(window.attachEvent && !window.opera)) {
        styleNode.styleSheet.cssText = 'span { color: rgb(255, 0, 0); }';
   } else {
        var styleText = document.createTextNode('span { color: rgb(255, 0, 0); } ');
        styleNode.appendChild(styleText);
   }
   document.getElementsByTagName('head')[0].appendChild(styleNode);
 </script>
</html>

Also, I noticed in your question that you are using innerHTML. This is actually a non-standard way of inserting data into a page. The best practice is to create a text node and append it to another element node.

With respect to your final question, you're going to hear some people say that your work should work across all of the browsers. It all depends on your audience. If no one in your audience is using Chrome, then don't sweat it; however, if you're looking to reach the biggest audience possible, then it's best to support all major A-grade browsers

For all files (default setting for opened file): Settings/Preferences | Editor | General | Use soft wraps in editor

For currently opened file in editor: Menu | View | Active Editor | Use Soft Wraps

In latest IDE versions you can also access this option via context menu for the editor gutter area (the area with line numbers on the left side of the editor).

Search Everywhere (Shift 2x times) or Help | Find Action... ( Ctrl + Shift+ A on Windows using Default keymap) can also be used to quickly change this option (instead of going into Settings/Preferences).

As eaon21 and monkey said, source map files basically turn minified code into its unminified version for debugging.

You can find the .map files here. Just add them into the same directory as the minified js files and it'll stop complaining. The reason they get fetched is the

/*

at the end of angular.min.js. If you don't want to add the .map files you can remove those lines and it'll stop the fetch attempt, but if you plan on debugging it's always good to keep the source maps linked.

There are many ways to achieve this, like flatten-and-filter or simply enumerate, but I think using Boolean/mask array is the easiest one (and iirc a much faster one):

>>> y = np.array([[123,24123,32432], [234,24,23]])
array([[  123, 24123, 32432],
       [  234,    24,    23]])
>>> b = y > 200
>>> b
array([[False,  True,  True],
       [ True, False, False]], dtype=bool)
>>> y[b]
array([24123, 32432,   234])
>>> len(y[b])
3
>>>> y[b].sum()
56789

Update:

As nneonneo has answered, if all you want is the number of elements that passes threshold, you can simply do:

>>>> (y>200).sum()
3

which is a simpler solution.

Speed comparison with filter:

### use boolean/mask array ###

b = y > 200

%timeit y[b]
100000 loops, best of 3: 3.31 us per loop

%timeit y[y>200]
100000 loops, best of 3: 7.57 us per loop

### use filter ###

x = y.ravel()
%timeit filter(lambda x:x>200, x)
100000 loops, best of 3: 9.33 us per loop

%timeit np.array(filter(lambda x:x>200, x))
10000 loops, best of 3: 21.7 us per loop

%timeit filter(lambda x:x>200, y.ravel())
100000 loops, best of 3: 11.2 us per loop

%timeit np.array(filter(lambda x:x>200, y.ravel()))
10000 loops, best of 3: 22.9 us per loop

*** use numpy.where ***

nb = np.where(y>200)
%timeit y[nb]
100000 loops, best of 3: 2.42 us per loop

%timeit y[np.where(y>200)]
100000 loops, best of 3: 10.3 us per loop

I accomplished the above using relative positioning and floating to the right.

HTML code:

<div class="clearfix">                          
    <div class="outer-div">
        <div class="inner-div">
            <div class="floating-div">Float 1</div>
            <div class="floating-div">Float 2</div>
            <div class="floating-div">Float 3</div>
        </div>
    </div>
</div>

CSS:

.outer-div { position: relative; float: right; right: 50%; }
.inner-div { position: relative; float: right; right: -50%; }
.floating-div { float: left; border: 1px solid red; margin: 0 1.5em; }

.clearfix:before,
.clearfix:after { content: " "; display: table; }
.clearfix:after { clear: both; }
.clearfix { *zoom: 1; }

This will work in IE8 and up, but not earlier (surprise, surprise!)

I do not recall the source of this method unfortunately, so I cannot give credit to the original author. If anybody else knows, please post the link!

A simple solution could be:

interface bar {
    length: number;
}

let bars: bar[];
bars = [];

Here is a bit improved version of shekwi's query.
It generates the primary key constraint and is able to handle temporary tables:

with pkey as
(
    select cc.conrelid, format(E',
    constraint %I primary key(%s)', cc.conname,
        string_agg(a.attname, ', ' 
            order by array_position(cc.conkey, a.attnum))) pkey
    from pg_catalog.pg_constraint cc
        join pg_catalog.pg_class c on c.oid = cc.conrelid
        join pg_catalog.pg_attribute a on a.attrelid = cc.conrelid 
            and a.attnum = any(cc.conkey)
    where cc.contype = 'p'
    group by cc.conrelid, cc.conname
)
select format(E'create %stable %s%I\n(\n%s%s\n);\n',
    case c.relpersistence when 't' then 'temporary ' else '' end,
    case c.relpersistence when 't' then '' else n.nspname || '.' end,
    c.relname,
    string_agg(
        format(E'\t%I %s%s',
            a.attname,
            pg_catalog.format_type(a.atttypid, a.atttypmod),
            case when a.attnotnull then ' not null' else '' end
        ), E',\n'
        order by a.attnum
    ),
    (select pkey from pkey where pkey.conrelid = c.oid)) as sql
from pg_catalog.pg_class c
    join pg_catalog.pg_namespace n on n.oid = c.relnamespace
    join pg_catalog.pg_attribute a on a.attrelid = c.oid and a.attnum > 0
    join pg_catalog.pg_type t on a.atttypid = t.oid
where c.relname = :table_name
group by c.oid, c.relname, c.relpersistence, n.nspname;

Use table_name parameter to specify the name of the table.

The problem with :hover is that IE6 only supports it on links. I use jQuery for this kind of thing these days:

$("div input").hover(function() {
  $(this).addClass("blue");
}, function() {
  $(this).removeClass("blue");
});

Makes things a lot easier. That'll work in IE6, FF, Chrome and Safari.

Simple way to import data from your googledrive - doing this save people time (don't know why google just doesn't list this step by step explicitly).

INSTALL AND AUTHENTICATE PYDRIVE

     !pip install -U -q PyDrive ## you will have install for every colab session

     from pydrive.auth import GoogleAuth
     from pydrive.drive import GoogleDrive
     from google.colab import auth
     from oauth2client.client import GoogleCredentials

     # 1. Authenticate and create the PyDrive client.
     auth.authenticate_user()
     gauth = GoogleAuth()
     gauth.credentials = GoogleCredentials.get_application_default()
     drive = GoogleDrive(gauth)

UPLOADING

if you need to upload data from local drive:

    from google.colab import files

    uploaded = files.upload()

    for fn in uploaded.keys():
       print('User uploaded file "{name}" with length {length} bytes'.format(name=fn, length=len(uploaded[fn])))

execute and this will display a choose file button - find your upload file - click open

After uploading, it will display:

    sample_file.json(text/plain) - 11733 bytes, last modified: x/xx/2018 - %100 done
    User uploaded file "sample_file.json" with length 11733 bytes

CREATE FILE FOR NOTEBOOK

If your data file is already in your gdrive, you can skip to this step.

Now it is in your google drive. Find the file in your google drive and right click. Click get 'shareable link.' You will get a window with:

    https://drive.google.com/open?id=29PGh8XCts3mlMP6zRphvnIcbv27boawn

Copy - '29PGh8XCts3mlMP6zRphvnIcbv27boawn' - that is the file ID.

In your notebook:

    json_import = drive.CreateFile({'id':'29PGh8XCts3mlMP6zRphvnIcbv27boawn'})

    json_import.GetContentFile('sample.json') - 'sample.json' is the file name that will be accessible in the notebook.

IMPORT DATA INTO NOTEBOOK

To import the data you uploaded into the notebook (a json file in this example - how you load will depend on file/data type - .txt,.csv etc. ):

    sample_uploaded_data = json.load(open('sample.json'))

Now you can print to see the data is there:

    print(sample_uploaded_data)

If d = date(2011, 1, 1) is in UTC:

>>> from datetime import datetime, date
>>> import calendar
>>> timestamp1 = calendar.timegm(d.timetuple())
>>> datetime.utcfromtimestamp(timestamp1)
datetime.datetime(2011, 1, 1, 0, 0)

If d is in local timezone:

>>> import time
>>> timestamp2 = time.mktime(d.timetuple()) # DO NOT USE IT WITH UTC DATE
>>> datetime.fromtimestamp(timestamp2)
datetime.datetime(2011, 1, 1, 0, 0)

timestamp1 and timestamp2 may differ if midnight in the local timezone is not the same time instance as midnight in UTC.

mktime() may return a wrong result if d corresponds to an ambiguous local time (e.g., during DST transition) or if d is a past(future) date when the utc offset might have been different and the C mktime() has no access to the tz database on the given platform. You could use pytz module (e.g., via tzlocal.get_localzone()) to get access to the tz database on all platforms. Also, utcfromtimestamp() may fail and mktime() may return non-POSIX timestamp if "right" timezone is used.

To convert datetime.date object that represents date in UTC without calendar.timegm():

DAY = 24*60*60 # POSIX day in seconds (exact value)
timestamp = (utc_date.toordinal() - date(1970, 1, 1).toordinal()) * DAY
timestamp = (utc_date - date(1970, 1, 1)).days * DAY

How can I get a date converted to seconds since epoch according to UTC?

To convert datetime.datetime (not datetime.date) object that already represents time in UTC to the corresponding POSIX timestamp (a float).

Python 3.3+

datetime.timestamp():

from datetime import timezone

timestamp = dt.replace(tzinfo=timezone.utc).timestamp()

Note: It is necessary to supply timezone.utc explicitly otherwise .timestamp() assume that your naive datetime object is in local timezone.

Python 3 (< 3.3)

From the docs for datetime.utcfromtimestamp():

There is no method to obtain the timestamp from a datetime instance, but POSIX timestamp corresponding to a datetime instance dt can be easily calculated as follows. For a naive dt:

timestamp = (dt - datetime(1970, 1, 1)) / timedelta(seconds=1)

And for an aware dt:

timestamp = (dt - datetime(1970,1,1, tzinfo=timezone.utc)) / timedelta(seconds=1)

Interesting read: Epoch time vs. time of day on the difference between What time is it? and How many seconds have elapsed?

See also: datetime needs an "epoch" method

Python 2

To adapt the above code for Python 2:

timestamp = (dt - datetime(1970, 1, 1)).total_seconds()

where timedelta.total_seconds() is equivalent to (td.microseconds + (td.seconds + td.days * 24 * 3600) * 10**6) / 10**6 computed with true division enabled.

Example

from __future__ import division
from datetime import datetime, timedelta

def totimestamp(dt, epoch=datetime(1970,1,1)):
    td = dt - epoch
    # return td.total_seconds()
    return (td.microseconds + (td.seconds + td.days * 86400) * 10**6) / 10**6 

now = datetime.utcnow()
print now
print totimestamp(now)

Beware of floating-point issues.

Output

2012-01-08 15:34:10.022403
1326036850.02

How to convert an aware datetime object to POSIX timestamp

assert dt.tzinfo is not None and dt.utcoffset() is not None
timestamp = dt.timestamp() # Python 3.3+

On Python 3:

from datetime import datetime, timedelta, timezone

epoch = datetime(1970, 1, 1, tzinfo=timezone.utc)
timestamp = (dt - epoch) / timedelta(seconds=1)
integer_timestamp = (dt - epoch) // timedelta(seconds=1)

On Python 2:

# utc time = local time              - utc offset
utc_naive  = dt.replace(tzinfo=None) - dt.utcoffset()
timestamp = (utc_naive - datetime(1970, 1, 1)).total_seconds()

array_count_values only works for integers and strings. If you happen to want counts for float/numeric values (and you are heedless of small variations in precision or representation), this works:

function arrayCountValues($arr) {
  $vals = [];
  foreach ($arr as $val) { array_push($vals,strval($val)); }
  $cnts = array_count_values($vals);
  arsort($cnts);
  return $cnts;
}

Note that I return $cnts with the keys as strings. It would be easy to reconvert them, but I'm trying to determine the mode for the values, so I only need to re-convert the first (several) values.

I tested a version which looped, creating an array of counts rather than using array_count_values, and this turned out to be more efficient (by maybe 8-10%)!

It's limited in that you can't put statements in there. You can only put values(or things that return/evaluate to values), to return

This works ('a' is a static int within class Blah)

Blah.a=Blah.a<5?1:8;

(round brackets are impicitly between the equals and the question mark).

This doesn't work.

Blah.a = Blah.a < 4 ? Console.WriteLine("asdf") : Console.WriteLine("34er");
or
Blah.a = Blah.a < 4 ? MessageBox.Show("asdf") : MessageBox.Show("34er");

So you can only use the c# ternary operator for returning values. So it's not quite like a shortened form of an if. Javascript and perhaps some other languages let you put statements in there.

using System;
using System.IO;
using System.Text;

class Test
{
    public static void Main()
    {
             string strToProcess = "fkdfdsfdflkdkfk@dfsdfjk72388389@kdkfkdfkkl@jkdjkfjd@jjjk@";
            strToProcess.Replace("@", Environment.NewLine);
            Console.WriteLine(strToProcess);
    }
}

ok, here is what i understood from your question. You are writing a csv file from python but when you are opening that file into some other application like excel or open office they are showing the complete row in one cell rather than each word in individual cell. I am right??

if i am then please try this,

import csv

with open(r"C:\\test.csv", "wb") as csv_file:
    writer = csv.writer(csv_file, delimiter =",",quoting=csv.QUOTE_MINIMAL)
    writer.writerow(["a","b"])

you have to set the delimiter = ","

I often do a quick "last week" check as well and the following tends to work well for me and includes today.

DECLARE @StartDate DATETIME 
DECLARE @EndDate DATETIME 

SET @StartDate = Getdate() - 7 /* Seven Days Earlier */
SET @EndDate = Getdate() /* Now */

SELECT id 
FROM   mytable 
WHERE  date BETWEEN @StartDate AND @Enddate 

If you want this to NOT include today just subtract an extra day from the @EndDate. If I select these two variables today get

@StartDate 2015-11-16 16:34:05.347 /* Last Monday */

@EndDate 2015-11-23 16:34:05.347 /* This Monday */

If I wanted Sunday to Sunday I would have the following.

SET @StartDate = Getdate() - 8 /* Eight Days Earlier */
SET @EndDate = Getdate() - 1  /* Yesterday */

@StartDate 2015-11-15 16:34:05.347 /* Previous Sunday */

@EndDate 2015-11-22 16:34:05.347 /* Last Sunday */

I had the same error, the problem was because I no longer had disk space. to check the space run this:

$ df -h

Then delete some files that you didn't need.

After this commands:

service mysql start
systemctl status mysql.service
mysql -u root -p

After entering with the root password verify that the mysql service was active

You can use getElementsByTagName function, it returns a HTMLCollection of elements with the given tag name.

var elements = document.getElementsByTagName("input")
for (var i = 0; i < elements.length; i++) {
    if(elements[i].value == "") {
        alert('empty');
        //Do something here
    }
}

DEMO

You can also use document.myform.getElementsByTagName provided you have given a name to yoy form

DEMO with form Name

oops! just found myself: just add this line on any element you need

   -webkit-appearance: none;

With Bootstrap 4:

if ($('#myModal').hasClass('show')) {
    alert("Modal is visible")
}

Well here is a solution for you but I don't really understand why it works:

<html><body>
  <div style="width: 200px; border: 1px solid red;">Test</div>
  <div style="width: 200px; border: 1px solid blue; overflow: hidden; height: 1.5em;">My hovercraft is full of eels.  These pretzels are making me thirsty.</div>
  <div style="width: 200px; border: 1px solid yellow; overflow: hidden; height: 1.5em;">
  This_is_a_terrible_example_of_thinking_outside_the_box.
  </div>
  <table style="border: 2px solid black; border-collapse: collapse; width: 200px;"><tr>
   <td style="width:200px; border: 1px solid green; overflow: hidden; height: 1.5em;"><div style="width: 200px; border: 1px solid yellow; overflow: hidden;">
    This_is_a_terrible_example_of_thinking_outside_the_box.
   </div></td>
  </tr></table>
</body></html>

Namely, wrapping the cell contents in a div.

Try this on your XML file

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        app:titleTextColor="@color/colorAccent"
        app:theme="@style/ToolbarColoredBackArrow"
        app:subtitleTextColor="@color/colorAccent"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" />

And add this is your colors.xml file

    <color name="colorAccent">YOUR_COLOR</color>

I can't seem to make that work without hacks either, so what I did was just use the drop-down menu in place of a select box and send the info through a hidden field, like so (using your code):

http://bootply.com/93417

Jquery:

$('.dropdown-menu li').click(function(e){
e.preventDefault();
  var selected = $(this).text();
  $('.category').val(selected);  
});

HTML:

<div class="container">
    <div class="col-sm-7 pull-right well">
      <form class="form-inline" action="#" method="get">
        <div class="input-group col-sm-8">
          <input class="form-control" type="text" value="" placeholder="Search" name="q">
       <div class="input-group-btn">
        <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">Select <span class="caret"></span></button>
        <ul class="dropdown-menu">
          <li><a href="#">1</a></li>
          <li><a href="#">2</a></li>
          <li><a href="#">3</a></li>
        </ul>
         <input type="hidden" name="category" class="category">
      </div><!-- /btn-group -->
        </div>
        <button class="btn btn-primary col-sm-3 pull-right" type="submit">Search</button>
      </form>
    </div>
</div>

Not sure if that will work for what you want, but it is an option for you.

"Case" can return single value only, but you can use complex type:

create type foo as (a int, b text);
select (case 1 when 1 then (1,'qq')::foo else (2,'ww')::foo end).*;

npm set registry http://85.10.209.91/

(this proxy fetches the original data from registry.npmjs.org and manipulates the tarball urls to fix the tarball file structure issue).

The other solutions seem to have outdated versions.

I had the same problem. I called my own custom logger in the log4j.properties file from code when using log4j api directly. If you are using the slf4j api calls, you are probably using the default root logger so you must configure that to be associated with an appender in the log4j.properties:

    # Set root logger level to DEBUG and its only appender to A1.
    log4j.rootLogger=DEBUG, A1

    # A1 is set to be a ConsoleAppender.
    log4j.appender.A1=org.apache.log4j.ConsoleAppender

Just add overflow:auto; to parent div

<div style="width: 100%;overflow:auto;">
    <div style="float:left; width: 80%">
    </div>
    <div style="float:right;">
    </div>
</div>

Working Demo

You could use dplyr::filter() and negate a grepl() match:

library(dplyr)

df %>% 
  filter(!grepl('REVERSE', Name))

Or with dplyr::filter() and negating a stringr::str_detect() match:

library(stringr)

df %>% 
  filter(!str_detect(Name, 'REVERSE'))

You can do it like this, too:

<?php
if(isset($_POST['select1'])){
    $select1 = $_POST['select1'];
    switch ($select1) {
        case 'value1':
            echo 'this is value1<br/>';
            break;
        case 'value2':
            echo 'value2<br/>';
            break;
        default:
            # code...
            break;
    }
}
?>


<form action="" method="post">
    <select name="select1">
        <option value="value1">Value 1</option>
        <option value="value2">Value 2</option>
    </select>
    <input type="submit" name="submit" value="Go"/>
</form>

Most people use symbols (that's the :foo_bar syntax). They're sort of unique opaque values. Symbols don't belong to any enum-style type so they're not really a faithful representation of C's enum type but this is pretty much as good as it gets.
