Memory management in Linux is a bit tricky to understand, and I can't say I fully understand it yet, but I'll try to share a little bit of my experience and knowledge.

Short answer to your question: Yes there are other stuff included than whats in the list.

What's being shown in your list is applications run in userspace. The kernel uses memory for itself and modules, on top of that it also has a lower limit of free memory that you can't go under. When you've reached that level it will try to free up resources, and when it can't do that anymore, you end up with an OOM problem.

From the last line of your list you can read that the kernel reports a total-vm usage of: 1498536kB (1,5GB), where the total-vm includes both your physical RAM and swap space. You stated you don't have any swap but the kernel seems to think otherwise since your swap space is reported to be full (Total swap = 524284kB, Free swap = 0kB) and it reports a total vmem size of 1,5GB.

Another thing that can complicate things further is memory fragmentation. You can hit the OOM killer when the kernel tries to allocate lets say 4096kB of continous memory, but there are no free ones availible.

Now that alone probably won't help you solve the actual problem. I don't know if it's normal for your program to require that amount of memory, but I would recommend to try a static code analyzer like cppcheck to check for memory leaks or file descriptor leaks. You could also try to run it through Valgrind to get a bit more information out about memory usage.

var str1 = 'abc';
var str2 = str1+' def'; // str2 is now 'abc def'

You can also get this error if the objects you're passing to the method are out of order. In other words say your method takes, in order, a string, an integer, and a date. If you pass a date, then a string, then an integer you will get the same error message.

I created a fully automated solution to add PS and CMD context items. Just run set_registry.cmd and it will update registry to add two buttons when click RMB on folder or inside some opened folder:

This will change owner of registry keys to admin and add context menus
Change registry to enable PS and CWD context menus

1. Go to EC2 Dashboard and click "Running Instances" on "Security Groups", select the group of your instance which you need to add security.
2. click on the "Inbound" tab
3. Click "Edit" Button (It will open an popup window)
4. click "Add Rule"
5. Select the "Custom ICMP rule - IPv4" as Type
6. Select "Echo Request" and "Echo Response" as the Protocol (Port Range by default show as "N/A)
7. Enter the "0.0.0.0/0" as Source
8. Click "Save"

In my experience over the past few months, I've realized that the best way to achieve this is:

class App extends React.Component{
  constructor(){
   super();
   this.state = {
    serverResponse: ''
   }
  }
  componentDidMount(){
     this.getData();
  }
  async getData(){
   const res = await axios.get('url-to-get-the-data');
   const { data } = await res;
   this.setState({serverResponse: data})
 }
 render(){
  return(
     <div>
       {this.state.serverResponse}
     </div>
  );
 }
}

If you are trying to make post request on events such as click, then call getData() function on the event and replace the content of it like so:

async getData(username, password){
 const res = await axios.post('url-to-post-the-data', {
   username,
   password
 });
 ...
}

Furthermore, if you are making any request when the component is about to load then simply replace async getData() with async componentDidMount() and change the render function like so:

render(){
 return (
  <div>{this.state.serverResponse}</div>
 )
}

The simplest solution would be to open Visual Studio, deactivate the TFS Plugin in Tools > Options > Source control and reopen the solution you want to clean. Visual Studio will ask to remove source controls bindings

In my case (running the server locally on windows) I needed to clean the cache after changing the httpd.conf file.

\modules\apache\bin> ./htcacheclean.exe -t

htons is host-to-network short

This means it works on 16-bit short integers. i.e. 2 bytes.

This function swaps the endianness of a short.

Your number starts out at:

0001 0011 1000 1001 = 5001

When the endianness is changed, it swaps the two bytes:

1000 1001 0001 0011 = 35091

SELECT *
FROM   sys.all_sql_modules
WHERE  definition LIKE '%CreatedDate%'

check program with this input:abc/if you got something like ab ac bc abc program works well and you need a stronger RAM otherwise the program is wrong.

All these answers with .ReadAllBytes(). Another, similar (I won't say duplicate, since they were trying to refactor their code) question was asked on SO here: Best way to read a large file into a byte array in C#?

A comment was made on one of the posts regarding .ReadAllBytes():

File.ReadAllBytes throws OutOfMemoryException with big files (tested with 630 MB file 
and it failed) – juanjo.arana Mar 13 '13 at 1:31

A better approach, to me, would be something like this, with BinaryReader:

public static byte[] FileToByteArray(string fileName)
{
    byte[] fileData = null;

    using (FileStream fs = File.OpenRead(fileName)) 
    { 
        var binaryReader = new BinaryReader(fs); 
        fileData = binaryReader.ReadBytes((int)fs.Length); 
    }
    return fileData;
}

But that's just me...

Of course, this all assumes you have the memory to handle the byte[] once it is read in, and I didn't put in the File.Exists check to ensure the file is there before proceeding, as you'd do that before calling this code.

open your terminal then use this command

cd /Users/youruser/Library/MobileDevice/Provisioning\ Profiles/

check first inside your folder by use this command

ls

then if all files not use, delete by use this command

rm *

Just to expand on the previous answer colorRampPalettecan handle more than two colors.

So for a more expanded "heat map" type look you can....

colfunc<-colorRampPalette(c("red","yellow","springgreen","royalblue"))
plot(rep(1,50),col=(colfunc(50)), pch=19,cex=2)

The resulting image:

I did all things necessary to add bundling to an MVC 3 web (I'm new to the existing solution). Styles.Render didn't work for me. I finally discovered I was simply missing a colon. In a master page: <%: Styles.Render("~/Content/Css") %> I'm still confused about why (on the same page) <% Html.RenderPartial("LogOnUserControl"); %> works without the colon.

This is the simplest way to do it.

let total = parseInt(('100,000.00'.replace(',',''))) + parseInt(('500,000.00'.replace(',','')))

You could initialize ReturnDate on the model before sending it to the view.

In the controller:

[HttpGet]
public ActionResult SomeAction()
{
    var viewModel = new MyActionViewModel
    {
        ReturnDate = System.DateTime.Now
    };

    return View(viewModel);
}

If you are talking about an actual database (an mdf file) you would Attach it

.sql files are typically run using SQL Server Management Studio. They are basically saved SQL statements, so could be anything. You don't "import" them. More precisely, you "execute" them. Even though the script may indeed insert data.

Also, to expand on Jamie F's answer, don't run a SQL file against your database unless you know what it is doing. SQL scripts can be as dangerous as unchecked exe's

More recent and much cleaner: use event.key. No more arbitrary number codes!

NOTE: The old properties (.keyCode and .which) are Deprecated.

node.addEventListener('keydown', function(event) {
    const key = event.key; // "a", "1", "Shift", etc.
});

If you want to make sure only single characters are entered, check key.length === 1, or that it is one of the characters you expect.

In my experience, this message occurs when the primary file (.mdf) has no space to save the metadata of the database. This file include the system tables and they only save their data into it.

Make some space in the file and the commands works again. That's all, Enjoy

If you are not using the transferTo feature or non-blocking features you will not notice a difference between traditional IO and NIO(2) because the traditional IO maps to NIO.

But if you can use the NIO features like transferFrom/To or want to use Buffers, then of course NIO is the way to go.

On ubuntu you can add this PPA Repository and use it to install python 3.7: https://launchpad.net/~jonathonf/+archive/ubuntu/python-3.7

Or a different PPA that provides several Python versions is Deadsnakes: https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa

See also here: https://askubuntu.com/questions/865554/how-do-i-install-python-3-6-using-apt-get (I know it says 3.6 in the url, but the deadsnakes ppa also contains 3.7 so you can use it for 3.7 just the same)

If you want "official" you'd have to install it from the sources from the site, get the code (which you already downloaded) and do this:

tar -xf Python-3.7.0.tar.xz
cd Python-3.7.0
./configure
make
sudo make install        <-- sudo is required.

This might take a while

Constructors don't return a type , just remove the return type which is void in your case. It would run fine then.

Motivation

Sometimes, we are want to get the picture but not need to download it to real files,

i.e., download the data and keep it on memory.

For example, If I use the machine learning method, train a model that can recognize an image with the number (bar code).

When I spider some websites and that have those images so I can use the model to recognize it,

and I don't want to save those pictures on my disk drive,

then you can try the below method to help you keep download data on memory.

from io import BytesIO
response = requests.get(url)
with BytesIO as io_obj:
    for chunk in response.iter_content(chunk_size=4096):

    io_obj = instance_io()
    cur_size = 0
    for chunk in response.iter_content(chunk_size=chunk_size):
        cur_size += chunk_size

Here goes the code. Which is able to compare arrays by any position.

var array1 = [4,8,10,9];

var array2 = [10,8,9,4];

var is_same = array1.length == array2.length && array1.every(function(element, index) {
    //return element === array2[index];
  if(array2.indexOf(element)>-1){
    return element = array2[array2.indexOf(element)];
  }
});
console.log(is_same);

You can simply use the command below to describe a table.

desc table-name

or

desc schema-name.table-name

Just try this code:

start "" "C:\Users\DiPesh\Desktop\vbscript\welcome.vbs"

and save as .bat, it works for me

1. You can add to .htaccess, httpd.conf or VirtualHost section
2. Header set X-Frame-Options SAMEORIGIN this is the best option

Allow from URI is not supported by all browsers. Reference: X-Frame-Options on MDN

Modern browsers support JSON.parse().

var arr_from_json = JSON.parse( json_string );

In browsers that don't, you can include the json2 library.

FragmentPagerAdapter: the fragment of each page the user visits will be stored in memory, although the view will be destroyed. So when the page is visible again, the view will be recreated but the fragment instance is not recreated. This can result in a significant amount of memory being used. FragmentPagerAdapter should be used when we need to store the whole fragment in memory. FragmentPagerAdapter calls detach(Fragment) on the transaction instead of remove(Fragment).

FragmentStatePagerAdapter: the fragment instance is destroyed when it is not visible to the User, except the saved state of the fragment. This results in using only a small amount of Memory and can be useful for handling larger data sets. Should be used when we have to use dynamic fragments, like fragments with widgets, as their data could be stored in the savedInstanceState.Also it won’t affect the performance even if there are large number of fragments.

No, how you are doing it is correct.

Yes, probably you can re/create one by including -f at the end of your command

Converting your value in milliseconds to days is simply (MsValue / 86,400,000)

We can get 1/1/1970 as numeric value by DATE(1970,1,1)

= (MsValueCellReference / 86400000) + DATE(1970,1,1)

Using your value of 1271664970687 and formatting it as dd/mm/yyyy hh:mm:ss gives me a date and time of 19/04/2010 08:16:11

In case of already committed DS_Store:

Finally, make a commit!

I had a similar issue where I was getting an error for a member in the class that wasn't mapped to the db column, it was just a holder for a List of another entity. I changed List to ArrayList and the error went away. I know, I really shouldn't do that in a mapped entity, and that's what DTO's are for. Just wanted to share in case someone finds this thread and the answers above don't apply or help.

Please try like this,

return Article::where('id',$article)->with(['products'=>function($products, $offset, $limit) {
    return $products->offset($offset*$limit)->limit($limit);
}])

You can take view from here as well.

FIRST SOLUTION

SELECT d1.ID,Name,City FROM Demo_User d1
INNER JOIN
(SELECT MAX(ID) AS ID FROM Demo_User GROUP By NAME) AS P ON (d1.ID=P.ID);

SECOND SOLUTION

SELECT * FROM (SELECT * FROM Demo_User ORDER BY ID DESC) AS T GROUP BY NAME ;

Try this query:

SELECT *
FROM table 
WHERE MONTH(FROM_UNIXTIME(columnName))= MONTH(CURDATE())

You can use:

((count = FIRSTV - SECONDV))

to avoid invoking a separate process, as per the following transcript:

pax:~$ FIRSTV=7
pax:~$ SECONDV=2
pax:~$ ((count = FIRSTV - SECONDV))
pax:~$ echo $count
5

If I understood you right, you want to copy $var in a file (if it's a string).

echo $var > $destdir

I've been having similar issues of a video not playing in IE11 on Windows 8.1. What I didn't realize was that I was running an N version of Windows, meaning no media features were installed. After installing the Media Feature Pack for N and KN versions of Windows 8.1 and rebooting my PC it was working fine.

As a side-note, the video worked fine in Chrome, Firefox, etc, since those browsers properly fell back to the webm file.

How about jQuery.makeArray(obj)

This is how I did it in my app.

*data interprets arguments as tuples, instead you have to pass **data which interprets the arguments as dictionary.

data = {'school':'DAV', 'class': '7', 'name': 'abc', 'city': 'pune'}


def my_function(**data):
    schoolname  = data['school']
    cityname = data['city']
    standard = data['class']
    studentname = data['name']

You can call the function like this:

my_function(**data)

>>> for i, s in enumerate(S):

If your only requirement is to print the third field of every line, with each field delimited by a comma, you can use cut:

cut -d, -f3 file

• -d, sets the delimiter to a comma
• -f3 specifies that only the third field is to be printed

The reason they call it a stack is because each level derives off its base layer. Your operating system, Linux, is the base layer. Then Apache, your web daemon sits on top of your OS. Then your database stores all the information served by your web daemon, and PHP (or any P* scripting language) is used to drive and display all the data, and allow for user interaction.

Don't be overly concerned with the term 'stack'. People really just mean software suite or bundle, but you're using it just fine I am sure as you are.

I just found a solution that I think works really well and gets around all of the pitfalls of custom symbols. The main problem with the li:before solution is that if list-items are longer than one line will not indent properly after the first line of text. By using text-indent with a negative padding we can circumvent that problem and have all the lines aligned properly:

ul{
    padding-left: 0; // remove default padding
}

li{
    list-style-type: none;  // remove default styles
    padding-left: 1.2em;    
    text-indent:-1.2em;     // remove padding on first line
}

li::before{
    margin-right:     0.5em; 
    width:            0.7em; // margin-right and width must add up to the negative indent-value set above
    height:           0.7em;

    display:          inline-block;
    vertical-align:   middle;
    border-radius: 50%;
    background-color: orange;
    content:          ' '
}

I have Windows 10 and PowerShell 5.1 was already installed. For whatever reason the x86 version works and can find "Install-Module", but the other version cannot.

Search your Start Menu for "powershell", and find the entry that ends in "(x86)":

Here is what I experience between the two different versions:

.* will match any characters in regular expressions

I think the java syntax would be

"digital".matches(".*ital.*");

And for the single character match just use a single dot.

"digital".matches(".*gi.a.*");

And to match an actual dot, escape it as slash dot

\.

At first I used James Lawruk's method. This however changed all the widths of the td's.

The solution for me was to use white-space: normal on the columns (which was set to white-space: nowrap). This way the text will always break. Using word-wrap: break-word will ensure that everything will break when needed, even halfway through a word.

The CSS will look like this then:

td, th {
    white-space: normal; /* Only needed when it's set differntly somewhere else */
    word-wrap: break-word;
}

This might not always be the desirable solution, as word-wrap: break-word might make your words in the table illegible. It will however keep your table the right width.

The curly braces inside backgroundImage property are wrong.

Probably you are using webpack along with image files loader, so Background should be already a String: backgroundImage: "url(" + Background + ")"

You can also use ES6 string templates as below to achieve the same effect:

backgroundImage: `url(${Background})`

If you're using jquery 1.6.2 you only need to code

$('#theid').css('display')

for example:

if($('#theid').css('display') == 'none'){ 
   $('#theid').show('slow'); 
} else { 
   $('#theid').hide('slow'); 
}

From https://gist.github.com/1180489

function pad(a, b){
  return(1e15 + a + '').slice(-b);
}

With comments:

function pad(
  a, // the number to convert 
  b // number of resulting characters
){
  return (
    1e15 + a + // combine with large number
    "" // convert to string
  ).slice(-b) // cut leading "1"
}

At first, you must specify your path, the path that your *.csv files are in there

path = 'f:\project\dataset'

You can change it based on your system.

then,

use dir function :

files = dir (strcat(path,'\*.csv'))

L = length (files);

for i=1:L
   image{i}=csvread(strcat(path,'\',file(i).name));   
   % process the image in here
end

pwd also can be used.

A panel expands to a span (or a div), with it's content within it. A placeholder is just that, a placeholder that's replaced by whatever you put in it.

Using IReadOnlyCollection<T> or IReadOnlyList<T> in the method signature instead of IEnumerable<T>, has the advantage of making explicit that you might need to check the count before iterating, or to iterate multiple times for some other reason.

However they have a huge downside that will cause problems if you try to refactor your code to use interfaces, for instance to make it more testable and friendly to dynamic proxying. The key point is that IList<T> does not inherit from IReadOnlyList<T>, and similarly for other collections and their respective read-only interfaces. (In short, this is because .NET 4.5 wanted to keep ABI compatibility with earlier versions. But they didn't even take the opportunity to change that in .NET core.)

This means that if you get an IList<T> from some part of the program and want to pass it to another part that expects an IReadOnlyList<T>, you can't! You can however pass an IList<T> as an IEnumerable<T>.

In the end, IEnumerable<T> is the only read-only interface supported by all .NET collections including all collection interfaces. Any other alternative will come back to bite you as you realize that you locked yourself out from some architecture choices. So I think it's the proper type to use in function signatures to express that you just want a read-only collection.

(Note that you can always write a IReadOnlyList<T> ToReadOnly<T>(this IList<T> list) extension method that simple casts if the underlying type supports both interfaces, but you have to add it manually everywhere when refactoring, where as IEnumerable<T> is always compatible.)

As always this is not an absolute, if you're writing database-heavy code where accidental multiple enumeration would be a disaster, you might prefer a different trade-off.

The right way is to execute npm update. It's a really powerful command, it updates the missing packages and also checks if a newer version of package already installed can be used.

Read Intro to NPM to understand what you can do with npm.

More recent answer in the case you want to delete every entries in every tables:

def reset
    Rails.application.eager_load!
    ActiveRecord::Base.descendants.each { |c| c.delete_all unless c == ActiveRecord::SchemaMigration  }
end

More information about the eager_load here.

After calling it, we can access to all of the descendants of ActiveRecord::Base and we can apply a delete_all on all the models.

Note that we make sure not to clear the SchemaMigration table.

Unfortunately, All the above answers are only half right.. Took a long time to figure this out..

Mongoose bson install via npm throws warning and causes the error...

npm install -g node-gyp

git clone https://github.com/mongodb/js-bson.git
cd js-bson

This works like magic!!

I had this error today with Amazon Cloudfront. It was because the cname I used (e.g cdn.example.com) was not added to the distribution settings under "alternate cnames", I only had cdn.example.com forwarded to the cloudfront domain in my site/hosting control panel, but you need to add it to Amazon CloudFront panel too.

I came across this thread while working on my understanding of Cython. My extension to the original question might be of use to others working at the C / Cython interface. So this is the extension of the original question: how do I return a string from a C function, making it available to Cython & thus to Python?

For those not familiar with it, Cython allows you to statically type Python code that you need to speed up. So the process is, enjoy writing Python :), find its a bit slow somewhere, profile it, calve off a function or two and cythonize them. Wow. Close to C speed (it compiles to C) Fixed. Yay. The other use is importing C functions or libraries into Python as done here.

This will print a string and return the same or another string to Python. There are 3 files, the c file c_hello.c, the cython file sayhello.pyx, and the cython setup file sayhello.pyx. When they are compiled using python setup.py build_ext --inplace they generate a shared library file that can be imported into python or ipython and the function sayhello.hello run.

c_hello.c

#include <stdio.h>

char *c_hello() {
  char *mystr = "Hello World!\n";
  return mystr;
  // return "this string";  // alterative
}

sayhello.pyx

cdef extern from "c_hello.c":
    cdef char* c_hello()

def hello():
    return c_hello()

setup.py

from setuptools import setup
from setuptools.extension import Extension
from Cython.Distutils import build_ext
from Cython.Build import cythonize


ext_modules = cythonize([Extension("sayhello", ["sayhello.pyx"])])


setup(
name = 'Hello world app',
cmdclass = {'build_ext': build_ext},
ext_modules = ext_modules
)

If your method doesn't have to return html and has to do something else then you can use a lambda instead of helper method in Razor

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";

    Func<int,int,int> Sum = (a, b) => a + b;
}

<h2>Index</h2>

@Sum(3,4)

The first element of the sites array is an array, as you can see indenting the JSON:

{"units":[{"id":42,               
    ...
    "sites":
    [
      [
        {
          "id":316,
          "article":42,
          "clip":133904
        }
      ],
      {"length":5}
    ]
    ...
}

Therefore you need to treat its value accordingly; probably you could do something like:

JSONObject site = (JSONObject)(((JSONArray)jsonSites.get(i)).get(0));

Given a list X

 import numpy as np
 X = [1, -1, 1, -1, 1]

The dictionary which shows i: frequency(i) for elements of this list is:

{i:X.count(i) for i in np.unique(X)}

Output:

{-1: 2, 1: 3}

Here's a full example that shows how to modify the fill color of an svg referenced via <embed>, <object> and <iframe>.

Also see How to apply a style to an embedded SVG?

A swift category that's mutating:

extension String {
    mutating func removeCharsFromEnd(removeCount:Int)
    {
        let stringLength = count(self)
        let substringIndex = max(0, stringLength - removeCount)
        self = self.substringToIndex(advance(self.startIndex, substringIndex))
    }
}

Use:

var myString = "abcd"
myString.removeCharsFromEnd(2)
println(myString) // "ab"

When calling a promise defined in a service or in a factory make sure to use service as I could not get response from a promise defined in a factory. This is how I call a promise defined in a service.

myApp.service('serverOperations', function($http) {
        this.get_data = function(user) {
          return $http.post('http://localhost/serverOperations.php?action=get_data', user);
        };
})


myApp.controller('loginCtrl', function($http, $q, serverOperations, user) {        
    serverOperations.get_data(user)
        .then( function(response) {
            console.log(response.data);
            }
        );
})

Since there's no language listed, I'll answer this in Swift. We highly recommend using Firebase Storage and the Firebase Realtime Database together to accomplish lists of downloads:

Shared:

// Firebase services
var database: FIRDatabase!
var storage: FIRStorage!
...
// Initialize Database, Auth, Storage
database = FIRDatabase.database()
storage = FIRStorage.storage()
...
// Initialize an array for your pictures
var picArray: [UIImage]()

Upload:

let fileData = NSData() // get data...
let storageRef = storage.reference().child("myFiles/myFile")
storageRef.putData(fileData).observeStatus(.Success) { (snapshot) in
  // When the image has successfully uploaded, we get it's download URL
  let downloadURL = snapshot.metadata?.downloadURL()?.absoluteString
  // Write the download URL to the Realtime Database
  let dbRef = database.reference().child("myFiles/myFile")
  dbRef.setValue(downloadURL)
}

Download:

let dbRef = database.reference().child("myFiles")
dbRef.observeEventType(.ChildAdded, withBlock: { (snapshot) in
  // Get download URL from snapshot
  let downloadURL = snapshot.value() as! String
  // Create a storage reference from the URL
  let storageRef = storage.referenceFromURL(downloadURL)
  // Download the data, assuming a max size of 1MB (you can change this as necessary)
  storageRef.dataWithMaxSize(1 * 1024 * 1024) { (data, error) -> Void in
    // Create a UIImage, add it to the array
    let pic = UIImage(data: data)
    picArray.append(pic)
  })
})

For more information, see Zero to App: Develop with Firebase, and it's associated source code, for a practical example of how to do this.

There is a alter way. Open the excel file in Microsoft office Excel, and save it as "Excel 97-2003 Workbook". Then, use the new saved excel file in your file connection.

Please check out my component that will help you to allow only a particular data type. Currently supporting integer, decimal, string and time(HH:MM).

• string - String is allowed with optional max length
• integer - Integer only allowed with optional max value
• decimal - Decimal only allowed with optional decimal points and max value (by default 2 decimal points)
• time - 24 hr Time format(HH:MM) only allowed

in oracle i believe these have exactly the same meaning

Preconditions: adb and wireshark are installed on your computer and you have a rooted android device.

1. Download tcpdump to ~/Downloads
2. adb push ~/Downloads/tcpdump /sdcard/
3. adb shell
4. su root
5. mv /sdcard/tcpdump /data/local/
6. cd /data/local/
7. chmod +x tcpdump
8. ./tcpdump -vv -i any -s 0 -w /sdcard/dump.pcap
9. Ctrl+C once you've captured enough data.
10. exit
11. exit
12. adb pull /sdcard/dump.pcap ~/Downloads/

Now you can open the pcap file using Wireshark.

As for your question about monitoring specific processes, find the bundle id of your app, let's call it com.android.myapp

1. ps | grep com.android.myapp
2. copy the first number you see from the output. Let's call it 1234. If you see no output, you need to start the app.
3. Download strace to ~/Downloads and put into /data/local using the same way you did for tcpdump above.
4. cd /data/local
5. ./strace -p 1234 -f -e trace=network -o /sdcard/strace.txt

Now you can look at strace.txt for ip addresses, and filter your wireshark log for those IPs.

I had an exact situation where the Parent-component had a Select element in a form and on submit, I needed to call the relevant Child-Component's method according to the selected value from the select element.

Parent.HTML:

<form (ngSubmit)='selX' [formGroup]="xSelForm">
    <select formControlName="xSelector">
      ...
    </select>
<button type="submit">Submit</button>
</form>
<child [selectedX]="selectedX"></child>

Parent.TS:

selX(){
  this.selectedX = this.xSelForm.value['xSelector'];
}

Child.TS:

export class ChildComponent implements OnChanges {
  @Input() public selectedX;

  //ngOnChanges will execute if there is a change in the value of selectedX which has been passed to child as an @Input.

  ngOnChanges(changes: { [propKey: string]: SimpleChange }) {
    this.childFunction();
  }
  childFunction(){ }
}

Hope this helps.

Here is how to create a DataFrame where each series is a row.

For a single Series (resulting in a single-row DataFrame):

series = pd.Series([1,2], index=['a','b'])
df = pd.DataFrame([series])

For multiple series with identical indices:

cols = ['a','b']
list_of_series = [pd.Series([1,2],index=cols), pd.Series([3,4],index=cols)]
df = pd.DataFrame(list_of_series, columns=cols)

For multiple series with possibly different indices:

list_of_series = [pd.Series([1,2],index=['a','b']), pd.Series([3,4],index=['a','c'])]
df = pd.concat(list_of_series, axis=1).transpose()

To create a DataFrame where each series is a column, see the answers by others. Alternatively, one can create a DataFrame where each series is a row, as above, and then use df.transpose(). However, the latter approach is inefficient if the columns have different data types.

I have put something like this in my Controller class and it worked:

IdentityUser user = await userManager.FindByNameAsync(HttpContext.User.Identity.Name);

where userManager is an instance of Microsoft.AspNetCore.Identity.UserManager class (with all weird setup that goes with it).

I like these NUnit Assert extensions: http://svn.caffeine-it.com/openrasta/trunk/src/Rasta.Testing/AssertExtensions.cs

You can try it:

Dim Price As Integer 
Int32.TryParse(txtPrice.Text, Price) 

If all you are looking for is to get your current working directory os.getcwd() will give you the same thing as os.path.dirname(__file__) as long as you have not changed the working directory elsewhere in your code. os.getcwd() also works in interactive mode.

So os.path.join(os.path.dirname(__file__)) becomes os.path.join(os.getcwd())

In Python 3, I find pathlib is the easiest way to do this. Request's response.content marries up nicely with pathlib's write_bytes.

from pathlib import Path
import requests
filename = Path('metadata.pdf')
url = 'http://www.hrecos.org//images/Data/forweb/HRTVBSH.Metadata.pdf'
response = requests.get(url)
filename.write_bytes(response.content)

From the title of this question I was expecting to find something like range(), that would let me specify two dates and create a list with all the dates in between. That way one does not need to calculate the number of days between those two dates, if one does not know it beforehand.

So with the risk of being slightly off-topic, this one-liner does the job:

import datetime
start_date = datetime.date(2011, 01, 01)
end_date   = datetime.date(2014, 01, 01)

dates_2011_2013 = [ start_date + datetime.timedelta(n) for n in range(int ((end_date - start_date).days))]

All credits to this answer!

In order to verify a client certificate is being sent to the server, you need to analyze the output from the combination of the -state and -debug flags.

First as a baseline, try running

$ openssl s_client -connect host:443 -state -debug

You'll get a ton of output, but the lines we are interested in look like this:

SSL_connect:SSLv3 read server done A
write to 0x211efb0 [0x21ced50] (12 bytes => 12 (0xC))
0000 - 16 03 01 00 07 0b 00 00-03                        .........
000c - <SPACES/NULS>
SSL_connect:SSLv3 write client certificate A

What's happening here:

• The -state flag is responsible for displaying the end of the previous section:

  SSL_connect:SSLv3 read server done A  
  

  This is only important for helping you find your place in the output.

• Then the -debug flag is showing the raw bytes being sent in the next step:

  write to 0x211efb0 [0x21ced50] (12 bytes => 12 (0xC))
  0000 - 16 03 01 00 07 0b 00 00-03                        .........
  000c - <SPACES/NULS>
  

• Finally, the -state flag is once again reporting the result of the step that -debug just echoed:

  SSL_connect:SSLv3 write client certificate A
  

So in other words: s_client finished reading data sent from the server, and sent 12 bytes to the server as (what I assume is) a "no client certificate" message.

If you repeat the test, but this time include the -cert and -key flags like this:

$ openssl s_client -connect host:443 \
   -cert cert_and_key.pem \
   -key cert_and_key.pem  \
   -state -debug

your output between the "read server done" line and the "write client certificate" line will be much longer, representing the binary form of your client certificate:

SSL_connect:SSLv3 read server done A
write to 0x7bd970 [0x86d890] (1576 bytes => 1576 (0x628))
0000 - 16 03 01 06 23 0b 00 06-1f 00 06 1c 00 06 19 31   ....#..........1
(*SNIP*)
0620 - 95 ca 5e f4 2f 6c 43 11-                          ..^%/lC.
SSL_connect:SSLv3 write client certificate A

The 1576 bytes is an excellent indication on its own that the cert was transmitted, but on top of that, the right-hand column will show parts of the certificate that are human-readable: You should be able to recognize the CN and issuer strings of your cert in there.

I had same question and I found this answer on this website.

And I changed it just a little bit (the curl_close at last line)

$username = 'myuser';
$password = 'mypass';
$loginUrl = 'http://www.example.com/login/';

//init curl
$ch = curl_init();

//Set the URL to work with
curl_setopt($ch, CURLOPT_URL, $loginUrl);

// ENABLE HTTP POST
curl_setopt($ch, CURLOPT_POST, 1);

//Set the post parameters
curl_setopt($ch, CURLOPT_POSTFIELDS, 'user='.$username.'&pass='.$password);

//Handle cookies for the login
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');

//Setting CURLOPT_RETURNTRANSFER variable to 1 will force cURL
//not to print out the results of its query.
//Instead, it will return the results as a string return value
//from curl_exec() instead of the usual true/false.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

//execute the request (the login)
$store = curl_exec($ch);

//the login is now done and you can continue to get the
//protected content.

//set the URL to the protected file
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/protected/download.zip');

//execute the request
$content = curl_exec($ch);

curl_close($ch);

//save the data to disk
file_put_contents('~/download.zip', $content);

I think this was what you were looking for.Am I right?

And one useful related question. About how to keep a session alive in cUrl: https://stackoverflow.com/a/13020494/2226796

var result = from x in entity
   join y in entity2 on new { x.field1, x.field2 } equals new { y.field1, y.field2 }

CASE might help you out:

SELECT t.first_name,
       t.last_name,
       t.employid,
       t.status
  FROM employeetable t
 WHERE t.status = (CASE WHEN status_flag = STATUS_ACTIVE THEN 'A'
                        WHEN status_flag = STATUS_INACTIVE THEN 'T'
                        ELSE null END)
   AND t.business_unit = (CASE WHEN source_flag = SOURCE_FUNCTION THEN 'production'
                               WHEN source_flag = SOURCE_USER THEN 'users'
                               ELSE null END)
   AND t.first_name LIKE firstname
   AND t.last_name LIKE lastname
   AND t.employid LIKE employeeid;

The CASE statement evaluates multiple conditions to produce a single value. So, in the first usage, I check the value of status_flag, returning 'A', 'T' or null depending on what it's value is, and compare that to t.status. I do the same for the business_unit column with a second CASE statement.

Since I have it installed globally, my favorite approach is to use nodemon. If your source code is in src, and your entry point is src/app.py, then it's as easy as:

nodemon -w 'src/**' -e py,html --exec python src/app.py

... where -e py,html lets you control what file types to watch for changes.

Steps for creating unsigned APK

Steps for creating unsigned APK_x000D_
_x000D_
• Click the dropdown menu in the toolbar at the top_x000D_
• Select "Edit Configurations"_x000D_
• Click the "+"_x000D_
• Select "Gradle"_x000D_
• Choose your module as a Gradle project_x000D_
• In Tasks: enter assemble_x000D_
• Press Run_x000D_
• Your unsigned APK is now located in - ProjectName\app\build\outputs\apk_x000D_
_x000D_
Note : Technically, what you want is an APK signed with a debug key. An APK that is actually unsigned will be refused by the device. So, Unsigned APK will give error if you install in device.

Try running all targets individually to check that all are running correct

run ant target name to run a target individually

e.g. ant build-project

Also the default target you specified is

project basedir="." default="build" name="iControlSilk4J"

This will only execute build-subprojects,build-project and init

As of Excel 2019 you could do this. The "Error" at the end is the default.

SWITCH(LEFT(A1,1), "A", "Pick Up", "B", "Collect", "C", "Prepaid", "Error")

Microsoft Excel Switch Documentation

The as keyword is useful when you genuinely don't know what type the variable might be. If you have a single function that will follow different code paths depending upon the actual type of the parameter, then you have two choices:

First, using a normal cast:

if(myObj is string)
{
    string value = (string)myObj;

    ... do something
}
else if(myObj is MyClass)
{
    MyClass = (MyClass)myObj;
}

This requires that you check the type of the object using is so that you don't try to cast it to something that will fail. This is also slightly redundant, as the is-type checking is done again in the cast (so that it can throw the exception if required).

The alternative is to use as.

string myString = myObj as string;
MyClass myClass = myObj as MyClass;

if(myString != null)
{

}
else if(myClass != null)
{

}

This makes the code somewhat shorter and also eliminates the redundant type checking.

I don't think it is possible to share a database link between more than one user but not all. They are either private (for one user only) or public (for all users).

A good way around this is to create a view in SCHEMA_B that exposes the table you want to access through the database link. This will also give you good control over who is allowed to select from the database link, as you can control the access to the view.

Do like this:

create database link db_link... as before;
create view mytable_view as select * from mytable@db_link;
grant select on mytable_view to myuser;

public ArrayAdapter (Context context, int resource, int textViewResourceId, T[] objects)

I am also new to Android , so i might be wrong. But as per my understanding while using this for listview creation 2nd argument is the layout of list items. A layout consists of many views (image view,text view etc). With 3rd argument you are specifying in which view or textview you want the text to be displayed.

The pyaudio website has many examples that are pretty short and clear: http://people.csail.mit.edu/hubert/pyaudio/

Update 14th of December 2019 - Main example from the above linked website from 2017:

"""PyAudio Example: Play a WAVE file."""

import pyaudio
import wave
import sys

CHUNK = 1024

if len(sys.argv) < 2:
    print("Plays a wave file.\n\nUsage: %s filename.wav" % sys.argv[0])
    sys.exit(-1)

wf = wave.open(sys.argv[1], 'rb')

p = pyaudio.PyAudio()

stream = p.open(format=p.get_format_from_width(wf.getsampwidth()),
                channels=wf.getnchannels(),
                rate=wf.getframerate(),
                output=True)

data = wf.readframes(CHUNK)

while data != '':
    stream.write(data)
    data = wf.readframes(CHUNK)

stream.stop_stream()
stream.close()

p.terminate()

This worked for me.

Adding where to find UPDATE CURRENT_TIMESTAMP because for new people this is a confusion.

Most people will use phpmyadmin or something like it.

Default value you select CURRENT_TIMESTAMP

Attributes (a different drop down) you select UPDATE CURRENT_TIMESTAMP

./ refers to the current working directory, except in the require() function. When using require(), it translates ./ to the directory of the current file called. __dirname is always the directory of the current file.

For example, with the following file structure

/home/user/dir/files/config.json

{
  "hello": "world"
}

/home/user/dir/files/somefile.txt

text file

/home/user/dir/dir.js

var fs = require('fs');

console.log(require('./files/config.json'));
console.log(fs.readFileSync('./files/somefile.txt', 'utf8'));

If I cd into /home/user/dir and run node dir.js I will get

{ hello: 'world' }
text file

But when I run the same script from /home/user/ I get

{ hello: 'world' }

Error: ENOENT, no such file or directory './files/somefile.txt'
    at Object.openSync (fs.js:228:18)
    at Object.readFileSync (fs.js:119:15)
    at Object.<anonymous> (/home/user/dir/dir.js:4:16)
    at Module._compile (module.js:432:26)
    at Object..js (module.js:450:10)
    at Module.load (module.js:351:31)
    at Function._load (module.js:310:12)
    at Array.0 (module.js:470:10)
    at EventEmitter._tickCallback (node.js:192:40)

Using ./ worked with require but not for fs.readFileSync. That's because for fs.readFileSync, ./ translates into the cwd (in this case /home/user/). And /home/user/files/somefile.txt does not exist.

For UTF-16, the character needs four bytes (two code units) if it starts with 0xD800 or greater; such a character is called a "surrogate pair." More specifically, a surrogate pair has the form:

[0xD800 - 0xDBFF]  [0xDC00 - 0xDFF]

where [...] indicates a two-byte code unit with the given range. Anything <= 0xD7FF is one code unit (two bytes). Anything >= 0xE000 is invalid (except BOM markers, arguably).

See http://unicodebook.readthedocs.io/unicode_encodings.html, section 7.5.

looks like SimpleDateFormat is not checking the pattern strictly even after setLenient(false); method is applied on it, so i have used below method to validate if the date inputted is valid date or not as per supplied pattern.

import java.time.format.DateTimeParseException;
public boolean isValidFormat(String dateString, String pattern) {
    boolean valid = true;
    DateTimeFormatter formatter = DateTimeFormatter.ofPattern(pattern);
    try {
        formatter.parse(dateString);
    } catch (DateTimeParseException e) {
        valid = false;
    }
    return valid;
}

In SQL you can not have a variable array.
However, the best alternative solution is to use a temporary table.

if the day itself doesn't matter do this:

echo date('Y-m-d', strtotime(date('Y-m')." -1 month"));

Try the attribute disabled, but I think the you won't get the value of the radio buttons. Or set images instead like:

To see if the given object is a ES6 Promise, we can make use of this predicate:

function isPromise(p) {
  return p && Object.prototype.toString.call(p) === "[object Promise]";
}

Calling toString directly from the Object.prototype returns a native string representation of the given object type which is "[object Promise]" in our case. This ensures that the given object

• Bypasses false positives such as..:
  • Self-defined object type with the same constructor name ("Promise").
  • Self-written toString method of the given object.
• Works across multiple environment contexts (e.g. iframes) in contrast to instanceof or isPrototypeOf.

However, any particular host object, that has its tag modified via Symbol.toStringTag, can return "[object Promise]". This may be the intended result or not depending on the project (e.g. if there is a custom Promise implementation).

To see if the object is from a native ES6 Promise, we can use:

function isNativePromise(p) {
  return p && typeof p.constructor === "function"
    && Function.prototype.toString.call(p.constructor).replace(/\(.*\)/, "()")
    === Function.prototype.toString.call(/*native object*/Function)
      .replace("Function", "Promise") // replacing Identifier
      .replace(/\(.*\)/, "()"); // removing possible FormalParameterList 
}

According to this and this section of the spec, the string representation of function should be:

"function Identifier ( FormalParameterList_opt ) { FunctionBody }"

which is handled accordingly above. The FunctionBody is [native code] in all major browsers.

MDN: Function.prototype.toString

This works across multiple environment contexts as well.

There is a method specifically for this purpose:

data.splitlines()
['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']

This is the only thing that worked for me when I tried to run a java class from a batch file:

start "cmdWindowTitle" /B "javaw" -cp . testprojectpak.MainForm

You can customize the start command as you want for your project, by following the proper syntax:

Syntax
      START "title" [/Dpath] [options] "command" [parameters]

Key:
   title      : Text for the CMD window title bar (required)
   path       : Starting directory
   command    : The command, batch file or executable program to run
   parameters : The parameters passed to the command

Options:
   /MIN       : Minimized
   /MAX       : Maximized
   /WAIT      : Start application and wait for it to terminate
   /LOW       : Use IDLE priority class
   /NORMAL    : Use NORMAL priority class

Here is a Python 3 version using Selenium webdriver and Pillow. This program captures the screenshot of the whole page and crop the element based on its location. The element image will be available as image.png. Firefox supports saving element image directly using element.screenshot_as_png('image_name').

from selenium import webdriver
from PIL import Image

driver = webdriver.Chrome()
driver.get('https://www.google.co.in')

element = driver.find_element_by_id("lst-ib")

location = element.location
size = element.size

driver.save_screenshot("shot.png")

x = location['x']
y = location['y']
w = size['width']
h = size['height']
width = x + w
height = y + h

im = Image.open('shot.png')
im = im.crop((int(x), int(y), int(width), int(height)))
im.save('image.png')

Update

Now chrome also supports individual element screenshots. So you may directly capture the screenshot of the web element as given below.

from selenium import webdriver

driver = webdriver.Chrome()
driver.get('https://www.google.co.in')
image = driver.find_element_by_id("lst-ib").screenshot_as_png 
# or
# element = driver.find_element_by_id("lst-ib")
# element.screenshot_as_png("image.png")

The Problem

Indexes visible in a web browser for directories that do not contain an index.html or index.php file.

I had a lot of trouble with the configuration on Scientific Linux's httpd web server to stop showing these indexes.

The Configuration that did not work

httpd.conf virtual host directory directives:

<Directory /home/mydomain.com/htdocs>
    Options FollowSymLinks
    AllowOverride all
    Require all granted
</Directory>

and the addition of the following line to .htaccess:

Options -Indexes

Directory indexes were still showing up. .htaccess settings weren't working!

How could that be, other settings in .htaccess were working, so why not this one? What's going? It should be working! %#$&^$%@# !!

The Fix

Change httpd.conf's Options line to:

Options +FollowSymLinks

and restart the webserver.

From Apache's core mod page: ( https://httpd.apache.org/docs/2.4/mod/core.html#options )

Mixing Options with a + or - with those without is not valid syntax and will be rejected during server startup by the syntax check with an abort.

Voilà directory indexes were no longer showing up for directories that did not contain an index.html or index.php file.

Now What! A New Wrinkle

New entries started to show up in the 'error_log' when such a directory access was attempted:

[Fri Aug 19 02:57:39.922872 2016] [autoindex:error] [pid 12479] [client aaa.bbb.ccc.ddd:xxxxx] AH01276: Cannot serve directory /home/mydomain.com/htdocs/dir-without-index-file/: No matching DirectoryIndex (index.html,index.php) found, and server-generated directory index forbidden by Options directive

This entry is from the Apache module 'autoindex' with a LogLevel of 'error' as indicated by [autoindex:error] of the error message---the format is [module_name:loglevel].

To stop these new entries from being logged, the LogLevel needs to be changed to a higher level (e.g. 'crit') to log fewer---only more serious error messages.

Apache 2.4 LogLevels

See Apache 2.4's core directives for LogLevel.

emerg, alert, crit, error, warn, notice, info, debug, trace1, trace2, trace3, tracr4, trace5, trace6, trace7, trace8

Each level deeper into the list logs all the messages of any previous level(s).

Apache 2.4's default level is 'warn'. Therefore, all messages classified as emerg, alert, crit, error, and warn are written to error_log.

Additional Fix to Stop New error_log Entries

Added the following line inside the <Directory>..</Directory> section of httpd.conf:

LogLevel crit

The Solution 1

My virtual host's httpd.conf <Directory>..</Directory> configuration:

<Directory /home/mydomain.com/htdocs>
    Options +FollowSymLinks
    AllowOverride all
    Require all granted
    LogLevel crit
</Directory>

and adding to /home/mydomain.com/htdocs/.htaccess, the root directory of your website's .htaccess file:

Options -Indexes

If you don't mind the 'error' level messages, omit

LogLevel crit

Scientific Linux - Solution 2 - Disables mod_autoindex

No more autoindex'ing of directories inside your web space. No changes to .htaccess. But, need access to the httpd configuration files in /etc/httpd

1. Edit /etc/httpd/conf.modules.d/00-base.conf and comment the line:

   LoadModule autoindex_module modules/mod_autoindex.so
   

   by adding a # in front of it then save the file.

2. In the directory /etc/httpd/conf.d rename (mv)

   sudo mv autoindex.conf autoindex.conf.<something_else>
   

3. Restart httpd:

   sudo httpd -k restart
   

   or

   sudo apachectl restart
   

The autoindex_mod is now disabled.

Linux distros with ap2dismod/ap2enmod Commands

Disable autoindex module enter the command

    sudo a2dismod autoindex

to enable autoindex module enter

    sudo a2enmod autoindex

I had a similar problem and just found a way to solve it (by single-stepping through log4j-extras source, no less...)

The good news is that, unlike what's written everywhere, it turns out that you actually CAN configure TimeBasedRollingPolicy using log4j.properties (XML config not needed! At least in versions of log4j >1.2.16 see this bug report)

Here is an example:

log4j.appender.File = org.apache.log4j.rolling.RollingFileAppender
log4j.appender.File.rollingPolicy = org.apache.log4j.rolling.TimeBasedRollingPolicy
log4j.appender.File.rollingPolicy.FileNamePattern = logs/worker-${instanceId}.%d{yyyyMMdd-HHmm}.log

BTW the ${instanceId} bit is something I am using on Amazon's EC2 to distinguish the logs from all my workers -- I just need to set that property before calling PropertyConfigurator.configure(), as follow:

p.setProperty("instanceId", EC2Util.getMyInstanceId());
PropertyConfigurator.configure(p);

I came up with this similar situation and I resolved it quiet easily.Here is what I did. Assuming you already have the value in array at your aspx.cs page.

1)Put a hidden field in your aspx page and us the hidden field ID to store the array value.

 HiddenField2.Value = string.Join(",", myarray);

2)Now that the hidden field has the value stored, just separated by commas. Use this hidden field in JavaScript like this. Simply create an array in JavaScript and then store the value in that array by removing the commas.

var hiddenfield2 = new Array();
hiddenfield2=document.getElementById('<%=HiddenField2.ClientID%>').value.split(',');

This should solve your problem.

Just Install the oh-my-zsh plugins as described in this link.

It works best on macOS and Linux.

Basic Installation

Oh My Zsh is installed by running one of the following commands in your terminal. You can install this via the command-line with either curl or wget.

via curl

sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

via wget

sh -c "$(wget https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"

If anyone wants to use purely Java configuration instead of xml configuration of hibernate, use this:

You can configure Hibernate without using persistence.xml at all in Spring like like this:

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean()
{
Map<String, Object> properties = new Hashtable<>();
properties.put("javax.persistence.schema-generation.database.action",
"none");
HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
adapter.setDatabasePlatform("org.hibernate.dialect.MySQL5InnoDBDialect"); //you can change this if you have a different DB
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(adapter);
factory.setDataSource(this.springJpaDataSource());
factory.setPackagesToScan("package name");
factory.setSharedCacheMode(SharedCacheMode.ENABLE_SELECTIVE);
factory.setValidationMode(ValidationMode.NONE);
factory.setJpaPropertyMap(properties);
return factory;
}

Since you are not using persistence.xml, you should create a bean that returns DataSource which you specify in the above method that sets the data source:

@Bean
public DataSource springJpaDataSource()
{
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setUrl("jdbc:mysql://localhost/SpringJpa");
dataSource.setUsername("tomcatUser");
dataSource.setPassword("password1234");
return dataSource;
}

Then you use @EnableTransactionManagement annotation over this configuration file. Now when you put that annotation, you have to create one last bean:

@Bean
public PlatformTransactionManager jpaTransactionManager()
{
return new JpaTransactionManager(
this.entityManagerFactoryBean().getObject());
}

Now, don't forget to use @Transactional Annotation over those method that deal with DB.

Lastly, don't forget to inject EntityManager in your repository (This repository class should have @Repository annotation over it).

Use @RequestParam in your method arguments so Spring can bind them, also use the @RequestMapping.params array to narrow the method that will be used by spring. Sample code:

@RequestMapping("/userGrid", 
params = {"_search", "nd", "rows", "page", "sidx", "sort"})
public @ResponseBody GridModel getUsersForGrid(
@RequestParam(value = "_search") String search, 
@RequestParam(value = "nd") int nd, 
@RequestParam(value = "rows") int rows, 
@RequestParam(value = "page") int page, 
@RequestParam(value = "sidx") int sidx, 
@RequestParam(value = "sort") Sort sort) {
// Stuff here
}

This way Spring will only execute this method if ALL PARAMETERS are present saving you from null checking and related stuff.

There are three unique situations:

• 4 numbers, e.g. Margin="a,b,c,d".
• 2 numbers, e.g. Margin="a,b".
• 1 number, e.g. Margin="a".

4 Numbers

If there are 4 numbers, then its left, top, right, bottom (a clockwise circle starting from the middle left margin). First number is always the "West" like "WPF":

<object Margin="left,top,right,bottom"/>

Example: if we use Margin="10,20,30,40" it generates:

2 Numbers

If there are 2 numbers, then the first is left & right margin thickness, the second is top & bottom margin thickness. First number is always the "West" like "WPF":

<object Margin="a,b"/> // Equivalent to Margin="a,b,a,b".

Example: if we use Margin="10,30", the left & right margin are both 10, and the top & bottom are both 30.

1 Number

If there is 1 number, then the number is repeated (its essentially a border thickness).

<object Margin="a"/> // Equivalent to Margin="a,a,a,a".

Example: if we use Margin="20" it generates:

Update 2020-05-27

Have been working on a large-scale WPF application for the past 5 years with over 100 screens. Part of a team of 5 WPF/C#/Java devs. We eventually settled on either using 1 number (for border thickness) or 4 numbers. We never use 2. It is consistent, and seems to be a good way to reduce cognitive load when developing.

The rule:

All width numbers start on the left (the "West" like "WPF") and go clockwise (if two numbers, only go clockwise twice, then mirror the rest).

If you're on Python 2.5 or earlier, open the file and then use the file object in your redirection:

log = open("c:\\goat.txt", "w")
print >>log, "test"

If you're on Python 2.6 or 2.7, you can use print as a function:

from __future__ import print_function
log = open("c:\\goat.txt", "w")
print("test", file = log)

If you're on Python 3.0 or later, then you can omit the future import.

If you want to globally redirect your print statements, you can set sys.stdout:

import sys
sys.stdout = open("c:\\goat.txt", "w")
print ("test sys.stdout")

Or if you already have the data in a list and prefer the other Linq format :)

List<string> uids = new List<string>(){"1", "45", "20", "10"};
List<user> table = GetDataFromSomewhere();

List<user> newTable = table.Where(xx => uids.Contains(xx.uid)).ToList();

A slight modification to one of the answers that worked for me:

git init
git remote add origin PATH/TO/REPO
git pull origin master

to start working on the master branch straight away.

To properly load functions from ~/.config/fish/functions

You may set only ONE function inside file and name file the same as function name + add .fish extension.

This way changing file contents reload functions in opened terminals (note some delay may occur ~1-5s)

That way if you edit either by commandline

function name; function_content; end

then

funcsave name

you have user defined functions in console and custom made in the same order.

Use INSERT ... ON DUPLICATE KEY UPDATE

QUERY:

INSERT INTO table (id, name, age) VALUES(1, "A", 19) ON DUPLICATE KEY UPDATE    
name="A", age=19

To change the default property for your entire MATLAB session, see the documentation on how default properties are handled.

As an example:

set(0,'DefaultAxesFontSize',22)
x=1:200; y=sin(x);
plot(x,y)
title('hello'); xlabel('x'); ylabel('sin(x)')

Because you are creatin a table expression, you have to specify the structure of that table, you can achive this on two way:

1: In the select you can use the original columnnames (as in your first example), but with aggregates you have to use an alias (also in conflicting names). Like

sum(totalitems) as bkdqty

2: You need to specify the column names rigth after the name of the talbe, and then you just have to take care that the count of the names should mach the number of coulms was selected in the query. Like:

d (duration, bkdqty) 
AS (Select.... ) 

With the second solution both of your query will work!

I was having the same problem until I read Jon Skeet's answer about the debugger displaying a single backslash with a double backslash even though the string may have a single backslash. I was not aware of that. So I changed my code from

text2 = text1.Replace(@"\\", @"/");

to

text2 = text1.Replace(@"\", @"/");

and that solved the problem. Note: I'm interfacing and R.Net which uses single forward slashes in path strings.

In large this question has been answered but in small parts by everyone. I dealt with this just a minute ago.

I wanted to have a button tray at the bottom of a panel where the panel has 30px all around. The button tray had to be flush bottom and sides.

.panel
{
  padding: 30px;
}

.panel > .actions
{
  margin: -30px;
  margin-top: 30px;
  padding: 30px;
  width: auto;
}

I did a demo here with more flesh to drive the idea. However the key elements above are offset any parent padding with matching negative margins on the child. Then most critical if you want to run the child full-width then set width to auto. (as mentioned in a comment above by schlingel).

System.Globalization.CultureInfo ci = System.Globalization.CultureInfo.CurrentCulture;

string _pos = dblstr.Replace(".",
    ci.NumberFormat.NumberDecimalSeparator).Replace(",",
        ci.NumberFormat.NumberDecimalSeparator);

double _dbl = double.Parse(_pos);

Setting dataType:'json' will parse JSON for you:

$.ajax({
  type: 'GET',
  url: 'http://example/functions.php',
  data: {get_param: 'value'},
  dataType: 'json',
  success: function (data) {
    var names = data
    $('#cand').html(data);
  }
});

Or else you can use parseJSON:

var parsedJson = $.parseJSON(jsonToBeParsed);

Then you can iterate the following:

var j ='[{"id":"1","name":"test1"},{"id":"2","name":"test2"},{"id":"3","name":"test3"},{"id":"4","name":"test4"},{"id":"5","name":"test5"}]';

...by using $().each:

var json = $.parseJSON(j);
$(json).each(function (i, val) {
  $.each(val, function (k, v) {
    console.log(k + " : " + v);
  });
}); 

JSFiddle

Check that you don't have a .my.cnf hiding in your homedir. That was my problem.

tl;dr

Instant.ofEpochMilli ( 1_393_572_325_000L )
       .toString()

2014-02-28T07:25:25Z

Details

(a) You seem be confused as to what a Date is. As the answer by JB Nizet said, a Date tracks the number of milliseconds since the Unix epoch (first moment of 1970) in the UTC time zone (that is, with no time zone offset). So a Date has no time zone^†. And it has no "format". We create string representations from a Date's value, but the Date itself is not a String and has no String.

(b) You refer to a "UTC format". UTC is not a format, not I have heard of. UTC (Coordinated Universal Time) is the origin point of time zones. Time zones east of the Royal Observatory in Greenwich, London are some number of hours & minutes ahead of UTC. Westward time zones are behind UTC.

You seem to be referring to ISO 8601 formatted strings. You are using the optional format, omitting (1) the T from the middle, and (2) the offset-from-UTC at the end. Unless presenting the string to a user in the user interface of your app, I suggest you generally stick with the usual format:

• 2014-02-27T23:03:14+05:30
• 2014-02-27T23:03:14Z ('Z' for Zulu, or UTC, with an offset of +00:00)

(c) Avoid the 3 or 4 letter time zone codes. They are neither standardized nor unique. "IST" for example can mean either Indian Standard Time or Irish Standard Time.

(d) Put some effort into searching StackOverflow before posting. You would have found all your answers.

(e) Avoid the java.util.Date & Calendar classes bundled with Java. They are notoriously troublesome. Use either the Joda-Time library or Java 8’s new java.time package (inspired by Joda-Time, defined by JSR 310).

java.time

The java.time classes use standard ISO 8601 formats by default when parsing and generating strings.

OffsetDateTime odt = OffsetDateTime.parse( "2014-02-27T23:03:14+05:30" ); 
Instant instant = Instant.parse( "2014-02-27T23:03:14Z" );

Parse your count of milliseconds since the epoch of first moment of 1970 in UTC.

Instant instant = Instant.ofEpochMilli ( 1_393_572_325_000L );

instant.toString(): 2014-02-28T07:25:25Z

Adjust that Instant into a desired time zone.

ZoneId z = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = instant.atZone( z );

zdt.toString(): 2014-02-28T02:25:25-05:00[America/Montreal]

About java.time

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

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

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

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

Where to obtain the java.time classes?

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

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

Joda-Time

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

Joda-Time uses ISO 8601 as its defaults.

A Joda-Time DateTime object knows its on assigned time zone, unlike a java.util.Date object.

Generally better to specify a time zone explicitly rather than rely on default time zone.

Example Code

long input = 1393572325000L;
DateTime dateTimeUtc = new DateTime( input, DateTimeZone.UTC );

DateTimeZone timeZoneIndia = DateTimeZone.forID( "Asia/Kolkata" );
DateTimeZone timeZoneIreland = DateTimeZone.forID( "Europe/Dublin" );

DateTime dateTimeIndia = dateTimeUtc.withZone( timeZoneIndia );
DateTime dateTimeIreland = dateTimeIndia.withZone( timeZoneIreland );

// Use a formatter to create a String representation. The formatter can adjust time zone if you so desire.
DateTimeFormatter formatter = DateTimeFormat.forStyle( "FM" ).withLocale( Locale.CANADA_FRENCH ).withZone( DateTimeZone.forID( "America/Montreal" ) );
String output = formatter.print( dateTimeIreland );

Dump to console…

// All three of these date-time objects represent the *same* moment in the timeline of the Universe.
System.out.println( "dateTimeUtc: " + dateTimeUtc );
System.out.println( "dateTimeIndia: " + dateTimeIndia );
System.out.println( "dateTimeIreland: " + dateTimeIreland );

System.out.println( "output for Montréal: " + output );

When run…

dateTimeUtc: 2014-02-28T07:25:25.000Z
dateTimeIndia: 2014-02-28T12:55:25.000+05:30
dateTimeIreland: 2014-02-28T07:25:25.000Z
output for Montréal: vendredi 28 février 2014 02:25:25

^† Actually, java.util.Date does have a time zone. That time zone is assigned deep in its source code. Yet the class ignores that time zone for most practical purposes. And its toString method applies the JVM’s current default time zone rather than that internal time zone. Confusing? Yes. This is one of many reasons to avoid the old java.util.Date/.Calendar classes. Use java.time and/or Joda-Time instead.

var page = "http://somurl.com/asom.php.aspx";

var $dialog = $('<div></div>')
               .html('<iframe style="border: 0px; " src="' + page + '" width="100%" height="100%"></iframe>')
               .dialog({
                   autoOpen: false,
                   modal: true,
                   height: 625,
                   width: 500,
                   title: "Some title"
               });
$dialog.dialog('open');

Use this inside a function. This is great if you really want to load an external URL as an IFRAME. Also make sure that in you custom jqueryUI you have the dialog.

Apart from the accepted answer, I'm suggesting another alternative. Use QueryDSL, create a predicate and use the exists() method that accepts a predicate and returns Boolean.

One advantage with QueryDSL is you can use the predicate for complicated where clauses.

I know this was answered a while ago but just chiming with a simple solution here that I am surprised wasn't mentioned.

=RIGHT("0000" & A1, 4)

Whenever I need to pad I use something like the above. Personally I find it the simplest solution and easier to read.

You can easily change the match-type to 1 when you are looking for the greatest value or to -1 when looking for the smallest value.

This answer describes a solution using MVVM.

This solution is great if you want to add a logging box to a window, that automatically scrolls to the bottom each time a new logging message is added.

Once these attached properties are added, they can be reused anywhere, so it makes for very modular and reusable software.

Add this XAML:

<TextBox IsReadOnly="True"   
         Foreground="Gainsboro"                           
         FontSize="13" 
         ScrollViewer.HorizontalScrollBarVisibility="Auto"
         ScrollViewer.VerticalScrollBarVisibility="Auto"
         ScrollViewer.CanContentScroll="True"
         attachedBehaviors:TextBoxApppendBehaviors.AppendText="{Binding LogBoxViewModel.AttachedPropertyAppend}"                                       
         attachedBehaviors:TextBoxClearBehavior.TextBoxClear="{Binding LogBoxViewModel.AttachedPropertyClear}"                                    
         TextWrapping="Wrap">

Add this attached property:

public static class TextBoxApppendBehaviors
{
    #region AppendText Attached Property
    public static readonly DependencyProperty AppendTextProperty =
        DependencyProperty.RegisterAttached(
            "AppendText",
            typeof (string),
            typeof (TextBoxApppendBehaviors),
            new UIPropertyMetadata(null, OnAppendTextChanged));

    public static string GetAppendText(TextBox textBox)
    {
        return (string)textBox.GetValue(AppendTextProperty);
    }

    public static void SetAppendText(
        TextBox textBox,
        string value)
    {
        textBox.SetValue(AppendTextProperty, value);
    }

    private static void OnAppendTextChanged(
        DependencyObject d,
        DependencyPropertyChangedEventArgs args)
    {
        if (args.NewValue == null)
        {
            return;
        }

        string toAppend = args.NewValue.ToString();

        if (toAppend == "")
        {
            return;
        }

        TextBox textBox = d as TextBox;
        textBox?.AppendText(toAppend);
        textBox?.ScrollToEnd();
    }
    #endregion
}

And this attached property (to clear the box):

public static class TextBoxClearBehavior
{
    public static readonly DependencyProperty TextBoxClearProperty =
        DependencyProperty.RegisterAttached(
            "TextBoxClear",
            typeof(bool),
            typeof(TextBoxClearBehavior),
            new UIPropertyMetadata(false, OnTextBoxClearPropertyChanged));

    public static bool GetTextBoxClear(DependencyObject obj)
    {
        return (bool)obj.GetValue(TextBoxClearProperty);
    }

    public static void SetTextBoxClear(DependencyObject obj, bool value)
    {
        obj.SetValue(TextBoxClearProperty, value);
    }

    private static void OnTextBoxClearPropertyChanged(
        DependencyObject d,
        DependencyPropertyChangedEventArgs args)
    {
        if ((bool)args.NewValue == false)
        {
            return;
        }

        var textBox = (TextBox)d;
        textBox?.Clear();
    }
}   

Then, if you're using a dependency injection framework such as MEF, you can place all of the logging-specific code into it's own ViewModel:

Here's how it works:

• The ViewModel toggles the Attached Properties to control the TextBox.
• As it's using "Append", it's lightning fast.
• Any other ViewModel can generate logging messages by calling methods on the logging ViewModel.
• As we use the ScrollViewer built into the TextBox, we can make it automatically scroll to the bottom of the textbox each time a new message is added.

The only three literal characters which are treated specially in the replace clause are / (to close the clause), \ (to escape characters, backreference, &c.), and & (to include the match in the replacement). Therefore, all you need to do is escape those three characters:

sed "s/KEYWORD/$(echo $REPLACE | sed -e 's/\\/\\\\/g; s/\//\\\//g; s/&/\\\&/g')/g"

Example:

$ export REPLACE="'\"|\\/><&!"
$ echo fooKEYWORDbar | sed "s/KEYWORD/$(echo $REPLACE | sed -e 's/\\/\\\\/g; s/\//\\\//g; s/&/\\\&/g')/g"
foo'"|\/><&!bar

I was able to trigger an SDK download like this:

1. Close Android Studio
2. Open android studio, but be ready
3. Once you see "loading project", click cancel. (this will only appear for seconds on a fast machine)
4. The SDK download window appeared!

I've got the same issue, my model is binding from another form, I've added ng-change and ng-model and it still doesn't work:

<input type="hidden" id="pdf-url" class="form-control" ng-model="pdfUrl"/>

<ng-dropzone
  dropzone="dropzone"
  dropzone-config="dropzoneButtonCfg"
  model="pdfUrl">
</ng-dropzone>

An input #pdf-url gets data from dropzone (two ways binding), however, ng-change doesn't work in this case. $scope.$watch is a solution for me:

$scope.$watch('pdfUrl', function updatePdfUrl(newPdfUrl, oldPdfUrl) {
  if (newPdfUrl !== oldPdfUrl) {
    // It's updated - Do something you want here.
  }
});

Hope this help.

If the problem is 100% here

EffectSelectorForm effectSelectorForm = new EffectSelectorForm(Effects);

There's only one possible explanation: property/variable "Effects" is not initialized properly... Debug your code to see what you pass to your objects.

EDIT after several hours

There were some problems:

• MEF attribute [Import] didn't work as expected, so we replaced it for the time being with a manually populated List<>. While the collection was null, it was causing exceptions later in the code, when the method tried to get the type of the selected item and there was none.

• several event handlers weren't wired up to control events

Some problems are still present, but I believe OP's original problem has been fixed. Other problems are not related to this one.

The problem you encounter comes from the lack of call to super.prepareForReuse().

Some other solutions above, suggesting to update the UI of the cell from the delegate's functions, are leading to a flawed design where the logic of the cell's behaviour is outside of its class. Furthermore, it's extra code that can be simply fixed by calling super.prepareForReuse(). For example :

class myCell: UICollectionViewCell {

    // defined in interface builder
    @IBOutlet weak var viewSelection : UIView!

    override var isSelected: Bool {
        didSet {
            self.viewSelection.alpha = isSelected ? 1 : 0
        }
    }

    override func prepareForReuse() {
        // Do whatever you want here, but don't forget this :
        super.prepareForReuse()
        // You don't need to do `self.viewSelection.alpha = 0` here 
        // because `super.prepareForReuse()` will update the property `isSelected`

    }


    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
        self.viewSelection.alpha = 0
    }

}

With such design, you can even leave the delegate's functions collectionView:didSelectItemAt:/collectionView:didDeselectItemAt: all empty, and the selection process will be totally handled, and behave properly with the cells recycling.

Unfortunately, there isn't a TryParse() equivalent. If you create a new instance of a System.Guid and pass the string value in, you can catch the three possible exceptions it would throw if it is invalid.

Those are:

• ArgumentNullException
• FormatException
• OverflowException

I have seen some implementations where you can do a regex on the string prior to creating the instance, if you are just trying to validate it and not create it.

If you try calling equals on a null object reference, then you'll get a null pointer exception thrown.

Import in Java does not work at all, as it is evaluated at compile time only. (Treat it as shortcuts so you do not have to write fully qualified class names). At runtime there is no import at all, just FQCNs.

At runtime it is necessary that all classes you have referenced can be found by classloaders. (classloader infrastructure is sometimes dark magic and highly dependent on environment.) In case of an applet you will have to rig up your HTML tag properly and also provide necessary JAR archives on your server.

PS: Matching at runtime is done via qualified class names - class found under this name is not necessarily the same or compatible with class you have compiled against.

CREATE TABLE User (
user_id INT NOT NULL AUTO_INCREMENT,
userName VARCHAR(100) NOT NULL,
password VARCHAR(255) NOT NULL,
email VARCHAR(255) NOT NULL,
userImage  LONGBLOB NOT NULL, 
Favorite VARCHAR(255) NOT NULL,
PRIMARY KEY (user_id)
);

and

CREATE TABLE Event (
    EventID INT NOT NULL AUTO_INCREMENT, 
    PRIMARY KEY (EventID),
    EventName VARCHAR(100) NOT NULL,
    EventLocation VARCHAR(100) NOT NULL,
    EventPriceRange VARCHAR(100) NOT NULL,
    EventDate Date NOT NULL,
    EventTime Time NOT NULL,
    EventDescription VARCHAR(255) NOT NULL,
    EventCategory VARCHAR(255) NOT NULL,
    EventImage  LONGBLOB NOT NULL,

For everyone who is on windows and couldn't solve the duplicating bars issue with any of the solutions mentioned here. I had to install the colorama package as stated in tqdm's known issues which fixed it.

pip install colorama

Try it with this example:

from tqdm import tqdm
from time import sleep

for _ in tqdm(range(5), "All", ncols = 80, position = 0):
    for _ in tqdm(range(100), "Sub", ncols = 80, position = 1, leave = False):
        sleep(0.01)

Which will produce something like:

All:  60%|¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦                | 3/5 [00:03<00:02,  1.02s/it]
Sub:  50%|¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦                  | 50/100 [00:00<00:00, 97.88it/s]

You can import the css file on App.vue, inside the style tag.

<style>
  @import './assets/styles/yourstyles.css';
</style>

Also, make sure you have the right loaders installed, if you need any.

OSX users can follow by Nicolay77 or mikkom that uses the mdbtools utility. You can install it via Homebrew. Just have your homebrew installed and then go

$ homebrew install mdbtools

Then create one of the scripts described by the guys and use it. I've used mikkom's one, converted all my mdb files into sql.

$ ./to_mysql.sh myfile.mdb > myfile.sql

(which btw contains more than 1 table)

Like you said remote_repo_url is indeed the IP of the server, and yes it needs to be added on each PC, but it's easier to understand if you create the server first then ask each to clone it.

There's several ways to connect to the server, you can use ssh, http, or even a network drive, each has it's pros and cons. You can refer to the documentation about protocols and how to connect to the server

You can check the rest of chapter 4 for more detailed information, as it's talking about how to set up your own server

Try this one:

$withoutExt = preg_replace('/\\.[^.\\s]{3,4}$/', '', $filename);

So, this matches a dot followed by three or four characters which are not a dot or a space. The "3 or 4" rule should probably be relaxed, since there are plenty of file extensions which are shorter or longer.

You don't need regex to do this. Here's an example :

var str = "'SELECT___100E___7',24";
var afterComma = str.substr(str.indexOf(",") + 1); // Contains 24 //

You can't cast an Object array to an Integer array. You have to loop through all elements of a and cast each one individually.

Object[] a = new Object[1];
Integer b=1;
a[0]=b;
Integer[] c = new Integer[a.length];
for(int i = 0; i < a.length; i++)
{
    c[i] = (Integer) a[i];
}

Edit: I believe the rationale behind this restriction is that when casting, the JVM wants to ensure type-safety at runtime. Since an array of Objects can be anything besides Integers, the JVM would have to do what the above code is doing anyway (look at each element individually). The language designers decided they didn't want the JVM to do that (I'm not sure why, but I'm sure it's a good reason).

However, you can cast a subtype array to a supertype array (e.g. Integer[] to Object[])!

Below is a positive lookbehind JavaScript alternative showing how to capture the last name of people with 'Michael' as their first name.

1) Given this text:

const exampleText = "Michael, how are you? - Cool, how is John Williamns and Michael Jordan? I don't know but Michael Johnson is fine. Michael do you still score points with LeBron James, Michael Green Miller and Michael Wood?";

get an array of last names of people named Michael. The result should be: ["Jordan","Johnson","Green","Wood"]

2) Solution:

function getMichaelLastName2(text) {
  return text
    .match(/(?:Michael )([A-Z][a-z]+)/g)
    .map(person => person.slice(person.indexOf(' ')+1));
}

// or even
    .map(person => person.slice(8)); // since we know the length of "Michael "

3) Check solution

console.log(JSON.stringify(    getMichaelLastName(exampleText)    ));
// ["Jordan","Johnson","Green","Wood"]

Demo here: http://codepen.io/PiotrBerebecki/pen/GjwRoo

You can also try it out by running the snippet below.

const inputText = "Michael, how are you? - Cool, how is John Williamns and Michael Jordan? I don't know but Michael Johnson is fine. Michael do you still score points with LeBron James, Michael Green Miller and Michael Wood?";_x000D_
_x000D_
_x000D_

Per documentation, android:weightSum defines the maximum weight sum, and is calculated as the sum of the layout_weight of all the children if not specified explicitly.

Let's consider an example with a LinearLayout with horizontal orientation and 3 ImageViews inside it. Now we want these ImageViews always to take equal space. To acheive this, you can set the layout_weight of each ImageView to 1 and the weightSum will be calculated to be equal to 3 as shown in the comment.

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    <!-- android:weightSum="3" -->
    android:orientation="horizontal"
    android:layout_gravity="center">

   <ImageView
       android:layout_height="wrap_content"       
       android:layout_weight="1"
       android:layout_width="0dp"/>
  .....

weightSum is useful for having the layout rendered correctly for any device, which will not happen if you set width and height directly.

Use scipy.optimize.curve_fit. And not only for linear fit.

from scipy.optimize import curve_fit
import scipy

def fn(x, a, b, c):
    return a + b*x[0] + c*x[1]

# y(x0,x1) data:
#    x0=0 1 2
# ___________
# x1=0 |0 1 2
# x1=1 |1 2 3
# x1=2 |2 3 4

x = scipy.array([[0,1,2,0,1,2,0,1,2,],[0,0,0,1,1,1,2,2,2]])
y = scipy.array([0,1,2,1,2,3,2,3,4])
popt, pcov = curve_fit(fn, x, y)
print popt

You need to use the SUBTOTAL function. The SUBTOTAL function ignores rows that have been excluded by a filter.

The formula would look like this:

=SUBTOTAL(9,B1:B20)

The function number 9, tells it to use the SUM function on the data range B1:B20.

If you are 'filtering' by hiding rows, the function number should be updated to 109.

=SUBTOTAL(109,B1:B20)

The function number 109 is for the SUM function as well, but hidden rows are ignored.

If you see this intermittently on wifi or LAN, but your mobile internet connection seems ok, it is most likely your ISP's cheap gateway router is experiencing high traffic load.

You should trap these errors and display a reminder to the user to close any other apps using the network.

Test by running a couple of HD youtube videos on your desktop to reproduce, or just go to a busy Starbucks.

you can also use:

pip install package==0.5.*

which is more consistent and easy to read.

The best solution for your browser load time would be to use a server side script to join them all together into one big .js file. Make sure to gzip/minify the final version. Single request - nice and compact.

Alternatively, you can use DOM to create a <script> tag and set the src property on it then append it to the <head>. If you need to wait for that functionality to load, you can make the rest of your javascript file be called from the load event on that script tag.

This function is based on the functionality of jQuery $.getScript()

function loadScript(src, f) {
  var head = document.getElementsByTagName("head")[0];
  var script = document.createElement("script");
  script.src = src;
  var done = false;
  script.onload = script.onreadystatechange = function() { 
    // attach to both events for cross browser finish detection:
    if ( !done && (!this.readyState ||
      this.readyState == "loaded" || this.readyState == "complete") ) {
      done = true;
      if (typeof f == 'function') f();
      // cleans up a little memory:
      script.onload = script.onreadystatechange = null;
      head.removeChild(script);
    }
  };
  head.appendChild(script);
}

// example:
loadScript('/some-other-script.js', function() { 
   alert('finished loading');
   finishSetup();
 });

Express deprecated res.send(body, status).

Use res.status(status).send(body) instead

The first thing i noticed is that you have a semi colon just after your closing bracket for your if statement );

You should also try and clean up your if statement by declaring a variable for the answer separately.

function answers() {

var select = document.getElementById("mySelect");
var answer = select.options[select.selectedIndex].value;

    if(answer == "To measure time"){
        alert("Thats correct"); 
    }

}

Try this

SELECT distinct id
FROM  (SELECT id, ROW_NUMBER() OVER (ORDER BY  id) AS RowNum
      FROM table
      WHERE fid = 64) t

Or use RANK() instead of row number and select records DISTINCT rank

SELECT id
FROM  (SELECT id, ROW_NUMBER() OVER (PARTITION BY  id ORDER BY  id) AS RowNum
      FROM table
      WHERE fid = 64) t
WHERE t.RowNum=1

This also returns the distinct ids

well, just a quick and dirty suggestion for simple 1-level directory structure without spaces, [edit] and for directories containing only ONE type of files that I found useful (at some point from http://www.pcreview.co.uk/forums/can-check-if-folder-empty-bat-file-t1468868.html):

for /f %a in ('dir /ad/b') do if not exist %a\*.xml echo %a Empty

/ad : shows only directory entries
/b : use bare format (just names)

[edit] using plain asterisk to check for ANY file (%a\* above) won't work, thanks for correction

therefore, deleting would be:

for /f %a in ('dir /ad/b') do if not exist %a\*.xml rmdir %a

r := bufio.NewReader(os.Stdin)
for true {
    fmt.Print("Give me an interest:")
    t, _, _ := r.ReadLine()
    interests = append(interests, string(t))
    if len(t) == 0 {
        break;
    }
}
fmt.Println(interests)

I try to avoid regular expressions, but this appears to work:

string = re.sub("\s","",(string.lower()))[:-3]

You've probably miss-typed something above that bit of code or created your own class called IPAddress. If you're using the .net one, that function should be available.

Have you tried using System.Net.IPAddress just in case?

System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse("127.0.0.1");  //127.0.0.1 as an example

The docs on Microsoft's site have a complete example which works fine on my machine.

I am sure there is ANT tags to do it but have used this 7zip hack in .bat script. I use http://www.7-zip.org/ command line tool. All the times I use this for changing jdbc url within j2ee context.xml file.

mkdir .\temp-install
c:\apps\commands\7za.exe x -y mywebapp.war META-INF/context.xml -otemp-install\mywebapp
..here I have small tool to replace text in xml file..
c:\apps\commands\7za.exe u -y -tzip mywebapp.war ./temp-install/mywebapp/*
rmdir /Q /S .\temp-install

You could extract entire .war file (its zip after all), delete files, replace files, add files, modify files and repackage to .war archive file. But changing one file in a large .war archive this might be best extracting specific file and then update original archive.

When I open a "DOS" command prompt, I use a batch file which sets all of the options I need and adds my old-time dos utilities to the path too.

@set path=%path%;c:\utils
@doskey cd=cd/d $*
@cd \wip
@cmd.exe

The doskey line sets the CD command so that it will do both drive and folder simultaneously. If this doesn't work, it is possibly because of the version of windows that you're running.

This is the easiest way and will provide automatic updates.

This is an extremely broad subject. Basically, you can't really recover from memory corruption, but you can at least try to fail promptly. Here are a few techniques you could use:

• checksum constant data. If you have any configuration data which stays constant for a long time (including hardware registers you have configured), compute its checksum on initialization and verify it periodically. When you see a mismatch, it's time to re-initialize or reset.

• store variables with redundancy. If you have an important variable x, write its value in x1, x2 and x3 and read it as (x1 == x2) ? x2 : x3.

• implement program flow monitoring. XOR a global flag with a unique value in important functions/branches called from the main loop. Running the program in a radiation-free environment with near-100% test coverage should give you the list of acceptable values of the flag at the end of the cycle. Reset if you see deviations.

• monitor the stack pointer. In the beginning of the main loop, compare the stack pointer with its expected value. Reset on deviation.

Got it working. Here was my procedure:

1. Browse to the desired page
2. Open the dev console - F12 on Windows/Linux or option + ? + J on macOS
3. Select the Sources tab in chrome inspector
4. In the web browser window, hover over the desired element to initiate the popover
5. Hit F8 on Windows/Linux (or fn + F8 on macOS) while the popover is showing. If you have clicked anywhere on the actual page F8 will do nothing. Your last click needs to be somewhere in the inspector, like the sources tab
6. Go to the Elements tab in inspector
7. Find your popover (it will be nested in the trigger element's HTML)
8. Have fun modifying the CSS

In PHP DateTime (PHP >= 5.3)

$dt = new DateTime();
$dt->setTimezone(new DateTimeZone('UTC'));
echo $dt->getTimestamp();

If you can add another wrapping div "block3" you could do something like this.

 <html>
      <head>
      <style type="text/css">
      .block1 {color:red;width:120px;border:1px solid green; height: 100px;}
      .block3 {float:left; width:10px;}
      .block2 {color:blue;width:70px;border:2px solid black;position:relative;float:right;}
      </style>
      </head>

    <body>
    <div class='block1'>

        <div class='block3'>
            <p>text1</p>
            <p>text2</p>
        </div>

        <div class='block2'>block2</DIV>

    </div>

    </body>
    </html>

No, you can not.

You can call a function from a stored procedure and debug a stored procedure (this will step into the function)

Below code helps to zoom UIImageView without using UIScrollView :

-(void)HandlePinch:(UIPinchGestureRecognizer*)recognizer{
    if ([recognizer state] == UIGestureRecognizerStateEnded) {
        NSLog(@"======== Scale Applied ===========");
        if ([recognizer scale]<1.0f) {
            [recognizer setScale:1.0f];
        }
        CGAffineTransform transform = CGAffineTransformMakeScale([recognizer scale],  [recognizer scale]);
        imgView.transform = transform;
    }
}

Use a SimpleDateFormat to parse the date and then print it out with a SimpleDateFormat withe the desired format.

Here's some code:

    SimpleDateFormat format1 = new SimpleDateFormat("MM/dd/yyyy");
    SimpleDateFormat format2 = new SimpleDateFormat("dd-MMM-yy");
    Date date = format1.parse("05/01/1999");
    System.out.println(format2.format(date));

Output:

01-May-99

Microsoft has a nice chart control. Download it here. Great video on this here. Example code is here. Happy coding!

document.getElementById('iframeid').src = document.getElementById('iframeid').src

It will reload the iframe, even across domains! Tested with IE7/8, Firefox and Chrome.

You can also handle index yourself if You need the index, it will not work if You need the key.

let i = 0;
for (const item of iterableItems) {
  // do something with index
  console.log(i);

  i++;
}

Try this:

System.Environment.CurrentDirectory

Try out this Card

Card(
    elevation: 10,
    shape: RoundedRectangleBorder(
      borderRadius: BorderRadius.circular(25.0), // half of height and width of Image
      ),
    child: Image.asset(
      "assets/images/home.png",
      width: 50,
      height: 50,
    ),
  )

Please follow @Sourav's advice.

If after restarting the server you get errors, you may need to set your directory options as well. This is done in the <Directory> tag in httpd.conf. Make sure the final config looks like this:

DocumentRoot "C:\alan"
<Directory "C:\alan">
    Options Indexes FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>

SELECT ...
SELECT SLEEP(5);
SELECT ...

But what are you using this for? Are you trying to circumvent/reinvent mutexes or transactions?

Try assigning a value to $aug1 before use it in if[] statements; the error message will disappear afterwards.

You can do it with using a FileOutputStream and the writeTo method.

ByteArrayOutputStream byteArrayOutputStream = getByteStreamMethod();
try(OutputStream outputStream = new FileOutputStream("thefilename")) {
    byteArrayOutputStream.writeTo(outputStream);
}

Source: "Creating a file from ByteArrayOutputStream in Java." on Code Inventions

Another option you can check the document.readyState like,

var chkReadyState = setInterval(function() {
    if (document.readyState == "complete") {
        // clear the interval
        clearInterval(chkReadyState);
        // finally your page is loaded.
    }
}, 100);

From the documentation of readyState Page the summary of complete state is

Returns "loading" while the document is loading, "interactive" once it is finished parsing but still loading sub-resources, and "complete" once it has loaded.

You have an error in your syntax here:

this._possessions = new Thing[100]();

This doesn't create an "array of things". To create an array of things, you can simply use the array literal expression:

this._possessions = [];

Of the array constructor if you want to set the length:

this._possessions = new Array(100);

I have created a brief working example you can try in the playground.

module Entities {  

    class Thing {

    }        

    export class Person {
        private _name: string;
        private _possessions: Thing[];
        private _mostPrecious: Thing;

        constructor (name: string) {
            this._name = name;
            this._possessions = [];
            this._possessions.push(new Thing())
            this._possessions[100] = new Thing();
        }
    }
}

i found something in the browser side itself.

Try this steps. here i have been mentioned the Steps to disable the Header and footer in all the three major browsers.

Chrome Click the Menu icon in the top right corner of the browser. Click Print. Uncheck Headers and Footers under the Options section.

Firefox Click Firefox in the top left corner of the browser. Place your mouse over Print, the click Page Setup. Click the Margins & Header/Footer tab. Change each value under Headers & Footers to --blank--.

Internet Explorer Click the Gear icon in the top right corner of the browser. Place your mouse over Print, then click Page Setup. Change each value under Headers and Footers to -Empty-.

Default values are only used if the arguments are not specified. In your case you did specify the arguments - both were supplied, with a value of NULL. (Yes, in this case NULL is considered a real value :-). Try:

EXEC TEST()

Share and enjoy.

Addendum: The default values for procedure parameters are certainly buried in a system table somewhere (see the SYS.ALL_ARGUMENTS view), but getting the default value out of the view involves extracting text from a LONG field, and is probably going to prove to be more painful than it's worth. The easy way is to add some code to the procedure:

CREATE OR REPLACE PROCEDURE TEST(X IN VARCHAR2 DEFAULT 'P',
                                 Y IN NUMBER DEFAULT 1)
AS
  varX VARCHAR2(32767) := NVL(X, 'P');
  varY NUMBER          := NVL(Y, 1);
BEGIN
  DBMS_OUTPUT.PUT_LINE('X=' || varX || ' -- ' || 'Y=' || varY);
END TEST;

Here's my example crontab I always use as a template:

    # Use the hash sign to prefix a comment
    # +---------------- minute (0 - 59)
    # |  +------------- hour (0 - 23)
    # |  |  +---------- day of month (1 - 31)
    # |  |  |  +------- month (1 - 12)
    # |  |  |  |  +---- day of week (0 - 7) (Sunday=0 or 7)
    # |  |  |  |  |
    # *  *  *  *  *  command to be executed
    #--------------------------------------------------------------------------

To run my cron job every Monday, Wednesady and Friday at 7:00PM, the result will be:

      0 19 * * 1,3,5 nohup /home/lathonez/script.sh > /tmp/script.log 2>&1

This *& in theory as well as in practical its possible and called as reference to pointer variable. and it's act like same. This *& combination is used in as function parameter for 'pass by' type defining. unlike ** can also be used for declaring a double pointer variable.
The passing of parameter is divided into pass by value, pass by reference, pass by pointer. there are various answer about "pass by" types available. however the basic we require to understand for this topic is.

pass by reference --> generally operates on already created variable refereed while passing to function e.g fun(int &a);

pass by pointer --> Operates on already initialized 'pointer variable/variable address' passing to function e.g fun(int* a);

auto addControl = [](SomeLabel** label, SomeControl** control) {
    *label = new SomeLabel;
    *control = new SomeControl;
    // few more operation further.
};

addControl(&m_label1,&m_control1);
addControl(&m_label2,&m_control2);
addControl(&m_label3,&m_control3);

in the above example(this is the real life problem i came across) i am trying to init few pointer variable from the lambda function and for that we need to pass it by double pointer, so that comes with d-referencing of pointer for its all usage inside of that lambda + while passing pointer in function which takes double pointer, you need to pass reference to the pointer variable.

so with this same thing reference to the pointer variable, *& this combination helps. in below given way for the same example i have mentioned above.

auto addControl = [](SomeLabel*& label, SomeControl*& control) {
        label = new SomeLabel;
        control = new SomeControl;
        // few more operation further.
    };

addControl(m_label1,m_control1);
addControl(m_label2,m_control2);
addControl(m_label3,m_control3);

so here you can see that you neither require d-referencing nor we require to pass reference to pointer variable while passing in function, as current pass by type is already reference to pointer.

Hope this helps :-)

The eval function will evaluate a string that is passed to it.

But the use of eval can be dangerous, so use with caution.

Edit: annakata has a good point -- Not only is eval dangerous, it is slow. This is because the code to be evaluated must be parsed on the spot, so that will take some computing resources.

I think I just discovered a way to apply overlapping conditions in the expected way using VBA. After hours of trying out different approaches I found that what worked was changing the "Applies to" range for the conditional format rule, after every single one was created!
