Just in case for data.table users, the following works for me:

df[, grep("ABC", names(df)), with = FALSE]

Well, it's clearly not a number since it has dashes in it. The error message and the two comments tell you that it is a factor but the commentators are apparently waiting and letting the message sink in. Dirk is suggesting that you do this:

 EPL2011_12$Date2 <- as.Date( as.character(EPL2011_12$Date), "%d-%m-%y")

After that you can do this:

 EPL2011_12FirstHalf <- subset(EPL2011_12, Date2 > as.Date("2012-01-13") )

R date functions assume the format is either "YYYY-MM-DD" or "YYYY/MM/DD". You do need to compare like classes: date to date, or character to character.

Assuming that you have a data frame called students, you can select individual rows or columns using the bracket syntax, like this:

• students[1,2] would select row 1 and column 2, the result here would be a single cell.
• students[1,] would select all of row 1, students[,2] would select all of column 2.

If you'd like to select multiple rows or columns, use a list of values, like this:

• students[c(1,3,4),] would select rows 1, 3 and 4,
• students[c("stu1", "stu2"),] would select rows named stu1 and stu2.

Hope I could help.

Do not use -which() for this, it is extremely dangerous. Consider:

dat <- data.frame(x=1:5, y=2:6, z=3:7, u=4:8)
dat[ , -which(names(dat) %in% c("z","u"))] ## works as expected
dat[ , -which(names(dat) %in% c("foo","bar"))] ## deletes all columns! Probably not what you wanted...

Instead use subset or the ! function:

dat[ , !names(dat) %in% c("z","u")] ## works as expected
dat[ , !names(dat) %in% c("foo","bar")] ## returns the un-altered data.frame. Probably what you want

I have learned this from painful experience. Do not overuse which()!

Try str_detect() from the stringr package, which detects the presence or absence of a pattern in a string.

Here is an approach that also incorporates the %>% pipe and filter() from the dplyr package:

library(stringr)
library(dplyr)

CO2 %>%
  filter(str_detect(Treatment, "non"))

   Plant        Type  Treatment conc uptake
1    Qn1      Quebec nonchilled   95   16.0
2    Qn1      Quebec nonchilled  175   30.4
3    Qn1      Quebec nonchilled  250   34.8
4    Qn1      Quebec nonchilled  350   37.2
5    Qn1      Quebec nonchilled  500   35.3
...

This filters the sample CO2 data set (that comes with R) for rows where the Treatment variable contains the substring "non". You can adjust whether str_detect finds fixed matches or uses a regex - see the documentation for the stringr package.

You could use the dplyr package:

library(dplyr)
filter(expr, cell_type == "hesc")
filter(expr, cell_type == "hesc" | cell_type == "bj fibroblast")

Similar to above, using filter from dplyr:

filter(df, fct %in% vc)

Prints all the rows with NA data:

tmp <- data.frame(c(1,2,3),c(4,NA,5));
tmp[round(which(is.na(tmp))/ncol(tmp)),]

Really human comprehensible example (as this is the first time I am using %in%), how to compare two data frames and keep only rows containing the equal values in specific column:

# Set seed for reproducibility.
set.seed(1)

# Create two sample data frames.
data_A <- data.frame(id=c(1,2,3), value=c(1,2,3))
data_B <- data.frame(id=c(1,2,3,4), value=c(5,6,7,8))

# compare data frames by specific columns and keep only 
# the rows with equal values 
data_A[data_A$id %in% data_B$id,]   # will keep data in data_A
data_B[data_B$id %in% data_A$id,]   # will keep data in data_b

Results:

> data_A[data_A$id %in% data_B$id,]
  id value
1  1     1
2  2     2
3  3     3

> data_B[data_B$id %in% data_A$id,]
  id value
1  1     5
2  2     6
3  3     7

> myMatrix <- matrix(1:10, nrow=2)
> rownames(myMatrix) <- c("A", "B")
> colnames(myMatrix) <- c("A", "B", "C", "D", "E")

> myMatrix
  A B C D  E
A 1 3 5 7  9
B 2 4 6 8 10

> myMatrix["A", "A"]
[1] 1

> myMatrix["A", ]
A B C D E 
1 3 5 7 9 

> myMatrix[, "A"]
A B 
1 2 

In case anyone else comes by and was still wondering, here's a function using Michael's explanation in C++

vector< vector<int> > getAllSubsets(vector<int> set)
{
    vector< vector<int> > subset;
    vector<int> empty;
    subset.push_back( empty );

    for (int i = 0; i < set.size(); i++)
    {
        vector< vector<int> > subsetTemp = subset;  //making a copy of given 2-d vector.

        for (int j = 0; j < subsetTemp.size(); j++)
            subsetTemp[j].push_back( set[i] );   // adding set[i] element to each subset of subsetTemp. like adding {2}(in 2nd iteration  to {{},{1}} which gives {{2},{1,2}}.

        for (int j = 0; j < subsetTemp.size(); j++)
            subset.push_back( subsetTemp[j] );  //now adding modified subsetTemp to original subset (before{{},{1}} , after{{},{1},{2},{1,2}}) 
    }
    return subset;
}

Take into account though, that this will return a set of size 2^N with ALL possible subsets, meaning there will possibly be duplicates. If you don't want this, I would suggest actually using a set instead of a vector(which I used to avoid iterators in the code).

Try new_list = a[0:2] + [a[4]] + a[6:].

Or more generally, something like this:

from itertools import chain
new_list = list(chain(a[0:2], [a[4]], a[6:]))

This works with other sequences as well, and is likely to be faster.

Or you could do this:

def chain_elements_or_slices(*elements_or_slices):
    new_list = []
    for i in elements_or_slices:
        if isinstance(i, list):
            new_list.extend(i)
        else:
            new_list.append(i)
    return new_list

new_list = chain_elements_or_slices(a[0:2], a[4], a[6:])

But beware, this would lead to problems if some of the elements in your list were themselves lists. To solve this, either use one of the previous solutions, or replace a[4] with a[4:5] (or more generally a[n] with a[n:n+1]).

Just to extend the answer above you can also index your columns rather than specifying the column names which can also be useful depending on what you're doing. Given that your location is the first field it would look like this:

    bar <- foo[foo[ ,1] == "there", ]

This is useful because you can perform operations on your column value, like looping over specific columns (and you can do the same by indexing row numbers too).

This is also useful if you need to perform some operation on more than one column because you can then specify a range of columns:

    foo[foo[ ,c(1:N)], ]

Or specific columns, as you would expect.

    foo[foo[ ,c(1,5,9)], ]

The expression df1$id %in% idNums1 produces a logical vector. To negate it, you need to negate the whole vector:

!(df1$id %in% idNums1)

mylist[c(5,7,9)] should do it.

You want the sublists returned as sublists of the result list; you don't use [[]] (or rather, the function is [[) for that -- as Dason mentions in comments, [[ grabs the element.

x <-dplyr::select(dataset_df, -c('coloumn1', 'column2'))

This works for me.

You can use %in%

  data[data$Code %in% selected,]
  Code Value
1    A     1
2    B     2
7    A     3
8    A     4

Regarding some points mentioned in previous answers, and to improve readability:

No need for data.loc or query, but I do think it is a bit long.

The parentheses are also necessary, because of the precedence of the & operator vs. the comparison operators.

I like to write such expressions as follows - less brackets, faster to type, easier to read. Closer to R, too.

q_product = df.Product == p_id
q_start = df.Time > start_time
q_end = df.Time < end_time

df.loc[q_product & q_start & q_end, c('Time,Product')]

# c is just a convenience
c = lambda v: v.split(',') 

If Multiset extends from the Array class

x = [1, 1, 2, 4, 7]
y = [1, 2, 2, 2]
z = [1, 1, 3, 7]

UNION

x.union(y)           # => [1, 2, 4, 7]      (ONLY IN RUBY 2.6)
x.union(y, z)        # => [1, 2, 4, 7, 3]   (ONLY IN RUBY 2.6)
x | y                # => [1, 2, 4, 7]

DIFFERENCE

x.difference(y)      # => [4, 7] (ONLY IN RUBY 2.6)
x.difference(y, z)   # => [4] (ONLY IN RUBY 2.6)
x - y                # => [4, 7]

INTERSECTION

x & y                # => [1, 2]

For more info about the new methods in Ruby 2.6, you can check this blog post about its new features

How about:

'%ni%' <- Negate('%in%')
c(1,3,11) %ni% 1:10
# [1] FALSE FALSE  TRUE

my.df <- read.table(textConnection("
v1 v2 v3 v4
a  v  d  c
a  v  d  d
b  n  p  g
b  d  d  h    
c  k  d  c    
c  r  p  g
d  v  d  x
d  v  d  c
e  v  d  b
e  v  d  c"), header = TRUE)

my.df[which(my.df$v1 != "b" & my.df$v1 != "d" & my.df$v1 != "e" ), ]

  v1 v2 v3 v4
1  a  v  d  c
2  a  v  d  d
5  c  k  d  c
6  c  r  p  g

In this case a relatively simple GROUP BY can work, but in general, when there are additional columns where you can't order by but you want them from the particular row which they are associated with, you can either join back to the detail using all the parts of the key or use OVER():

Runnable example (Wofkflow20 error in original data corrected)

;WITH partitioned AS (
    SELECT company
        ,workflow
        ,date
        ,other_columns
        ,ROW_NUMBER() OVER(PARTITION BY company, workflow
                            ORDER BY date) AS seq
    FROM workflowTable
)
SELECT *
FROM partitioned WHERE seq = 1

This my dynamical programming implementation in JS. It will return an array of arrays, each holding the subsequences summing to the provided target value.

function getSummingItems(a,t){_x000D_
  return a.reduce((h,n) => Object.keys(h)_x000D_
                                 .reduceRight((m,k) => +k+n <= t ? (m[+k+n] = m[+k+n] ? m[+k+n].concat(m[k].map(sa => sa.concat(n)))_x000D_
                                                                                      : m[k].map(sa => sa.concat(n)),m)_x000D_
                                                                 :  m, h), {0:[[]]})[t];_x000D_
}_x000D_
var arr = Array(20).fill().map((_,i) => i+1), // [1,2,..,20]_x000D_
    tgt = 42,_x000D_
    res = [];_x000D_
_x000D_
console.time("test");_x000D_
res = getSummingItems(arr,tgt);_x000D_
console.timeEnd("test");_x000D_
console.log("found",res.length,"subsequences summing to",tgt);_x000D_
console.log(JSON.stringify(res));

You want rows where that condition is true so you need a comma:

data[data$Ozone > 14, ]

You may also use the stringr package

library(dplyr)
library(stringr)
My.Data %>% filter(str_detect(x, '^G45'))

You may not use '^' (starts with) in this case, to obtain the results you need

If both the list are too big and when we use lamda expression then it will take a long time to fetch . Better to use linq in this case to fetch parameters list:

var items = (from x in parameters
                join y in myStrings on x.Source equals y
                select x)
            .ToList();

@agstudy's answer didn't work for me with the latest version of ggplot2, but this did, using maggritr pipes:

ggplot(data=dat)+ 
  geom_line(aes(Value1, Value2, group=ID, colour=ID),
                data = . %>% filter(ID %in% c("P1" , "P3")))

It works because if geom_line sees that data is a function, it will call that function with the inherited version of data and use the output of that function as data.

This is how I would do it, in order to get in the var4 restriction:

dfr<-data.frame(var1=rnorm(100), var2=rnorm(100), var3=rnorm(100, 160, 10), var4=rnorm(100, 27, 6))
plot( subset( dfr, var3 < 155 & var4 > 27, select = c( var1, var2 ) ) )

matches(); does not buffer, but find() buffers. find() searches to the end of the string first, indexes the result, and return the boolean value and corresponding index.

That is why when you have a code like

1:Pattern.compile("[a-z]");

2:Pattern.matcher("0a1b1c3d4");

3:int count = 0;

4:while(matcher.find()){

5:count++: }

At 4: The regex engine using the pattern structure will read through the whole of your code (index to index as specified by the regex[single character] to find at least one match. If such match is found, it will be indexed then the loop will execute based on the indexed result else if it didn't do ahead calculation like which matches(); does not. The while statement would never execute since the first character of the matched string is not an alphabet.

You may try

$("#addRunner input").each(function(){ ... });

Inputs are no selectors, so you do not need the : Haven't tested it with your code. Just a fast guess!

What everyone is forgeting is explaining WHY this happens.

A Char, is basically an integer, but with a pointer in the ASCII table. All characters have a corresponding integer value as you can clearly see when trying to parse it.

Pranay has clearly a different character set, thats why HIS code doesnt work. the only way is

int val = '1' - '0';

because this looks up the integer value in the table of '0' which is then the 'base value' subtracting your number in char format from this will give you the original number.

Being a fan of the Joda Time library, here's how you can do it that way using a Joda DateTime:

import org.joda.time.format.*;
import org.joda.time.*;

...    

String dateString = "2009-04-17 10:41:33";

// parse the string
DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd HH:mm:ss");
DateTime dateTime = formatter.parseDateTime(dateString);

// add two hours
dateTime = dateTime.plusHours(2); // easier than mucking about with Calendar and constants

System.out.println(dateTime);

If you still need to use java.util.Date objects before/after this conversion, the Joda DateTime API provides some easy toDate() and toCalendar() methods for easy translation.

The Joda API provides so much more in the way of convenience over the Java Date/Calendar API.

You can use PowerShell.

Below gives the total physical memory.

Apparently, not only the absolute speeds but also the speed order (as reported by user1579844) are machine dependent; here's what I found:

a=np.empty(1e4); a.fill(5) is fastest;

In descending speed order:

timeit a=np.empty(1e4); a.fill(5) 
# 100000 loops, best of 3: 10.2 us per loop
timeit a=np.empty(1e4); a[:]=5
# 100000 loops, best of 3: 16.9 us per loop
timeit a=np.ones(1e4)*5
# 100000 loops, best of 3: 32.2 us per loop
timeit a=np.tile(5,[1e4])
# 10000 loops, best of 3: 90.9 us per loop
timeit a=np.repeat(5,(1e4))
# 10000 loops, best of 3: 98.3 us per loop
timeit a=np.array([5]*int(1e4))
# 1000 loops, best of 3: 1.69 ms per loop (slowest BY FAR!)

So, try and find out, and use what's fastest on your platform.

You can use while(in.available() != 0) instead of while(true).

This is similar to https://stackoverflow.com/users/3396598/kohlbrr answer, but I was trying to get the total size of a single folder and found that the script doesn't count the files in the Root of the folder you are searching. This worked for me.

$startFolder = "C:\Users";
$totalSize = 0;

$colItems = Get-ChildItem $startFolder
foreach ($i in $colItems)
{
    $subFolderItems = Get-ChildItem $i.FullName -recurse -force | Where-Object {$_.PSIsContainer -eq $false} | Measure-Object -property Length -sum | Select-Object Sum
    $totalSize = $totalSize + $subFolderItems.sum / 1MB

}

$startFolder + " | " + "{0:N2}" -f ($totalSize) + " MB"

If you want to see the contents of RDD then yes collect is one option, but it fetches all the data to driver so there can be a problem

<rdd.name>.take(<num of elements you want to fetch>)

Better if you want to see just a sample

Running foreach and trying to print, I dont recommend this because if you are running this on cluster then the print logs would be local to the executor and it would print for the data accessible to that executor. print statement is not changing the state hence it is not logically wrong. To get all the logs you will have to do something like

**Pseudocode**
collect
foreach print

But this may result in job failure as collecting all the data on driver may crash it. I would suggest using take command or if u want to analyze it then use sample collect on driver or write to file and then analyze it.

public static void main (String[] args) {

     System.out.println("Simple Java Word Count Program");

     String str1 = "Today is Holdiay Day";

     String[] wordArray = str1.trim().split("\\s+");
     int wordCount = wordArray.length;

     System.out.println("Word count is = " + wordCount);
}

The ideas is to split the string into words on any whitespace character occurring any number of times. The split function of the String class returns an array containing the words as its elements. Printing the length of the array would yield the number of words in the string.

You can use .equals for columns or entire dataframes.

df['col1'].equals(df['col2'])

If they're equal, that statement will return True, else False.

Try to write your code between the HTML pre tag.

Use the function IF :

I'd do this:

1. add the dependency as you like in your pom:

           <artifactId>artifactId...</artifactId>
           <version>1.0</version>
   </dependency>
   

2. run mvn install it will try to download the jar and fail. On the process, it will give you the complete command of installing the jar with the error message. Copy that command and run it! easy huh?!

For hexadecimal code try this

1. Get ARGB (Alpha, Red, Green, Blue) representation for the color
2. Filter out Alpha channel: & 0x00FFFFFF
3. Format out the value (as hexadecimal "X6" for hex)

For RGB one

1. Just format out Red, Green, Blue values

Implementation

private static string HexConverter(Color c) {
  return String.Format("#{0:X6}", c.ToArgb() & 0x00FFFFFF);
}

public static string RgbConverter(Color c) {
  return String.Format("RGB({0},{1},{2})", c.R, c.G, c.B);
}

socket.disconnect() is a synonym to socket.close() which disconnect the socket manually.

When you type in client side :

const socket = io('http://localhost');

this will open a connection with autoConnect: true , so the lib will try to reconnect again when you disconnect the socket from server, to disable the autoConnection:

const socket = io('http://localhost', {autoConnect: false});
socket.open();// synonym to socket.connect()

And if you want you can manually reconnect:

socket.on('disconnect', () => {
  socket.open();
});

How about:

ACell.ListObject.DataBodyRange.Rows.Delete

That will keep your table structure and headings, but clear all the data and rows.

EDIT: I'm going to just modify a section of my answer from your previous post, as it does mostly what you want. This leaves just one row:

With loSource
   .Range.AutoFilter
   .DataBodyRange.Offset(1).Resize(.DataBodyRange.Rows.Count - 1, .DataBodyRange.Columns.Count).Rows.Delete
   .DataBodyRange.Rows(1).Specialcells(xlCellTypeConstants).ClearContents
End With

If you want to leave all the rows intact with their formulas and whatnot, just do:

With loSource
   .Range.AutoFilter
   .DataBodyRange.Specialcells(xlCellTypeConstants).ClearContents
End With

Which is close to what @Readify suggested, except it won't clear formulas.

armhf stands for "arm hard float", and is the name given to a debian port for arm processors (armv7+) that have hardware floating point support.

On the beaglebone black, for example:

:~$ dpkg --print-architecture
armhf

Although other commands (such as uname -a or arch) will just show armv7l

:~$ cat /proc/cpuinfo 
processor       : 0
model name      : ARMv7 Processor rev 2 (v7l)
BogoMIPS        : 995.32
Features        : half thumb fastmult vfp edsp thumbee neon vfpv3 tls
...

The vfpv3 listed under Features is what refers to the floating point support.

Incidentally, armhf, if your processor supports it, basically supersedes Raspbian, which if I understand correctly was mainly a rebuild of armhf with work arounds to deal with the lack of floating point support on the original raspberry pi's. Nowdays, of course, there's a whole ecosystem build up around Raspbian, so they're probably not going to abandon it. However, this is partly why the beaglebone runs straight debian, and that's ok even if you're used to Raspbian, unless you want some of the special included non-free software such as Mathematica.

It sounds like you basically want to take an ASCII string, or more preferably, a byte[] (as you can encode your string to a byte[] using your preferred encoding mode) into a string of ones and zeros? i.e. 101010010010100100100101001010010100101001010010101000010111101101010

This will do that for you...

//Formats a byte[] into a binary string (010010010010100101010)
public string Format(byte[] data)
{
    //storage for the resulting string
    string result = string.Empty;
    //iterate through the byte[]
    foreach(byte value in data)
    {
        //storage for the individual byte
        string binarybyte = Convert.ToString(value, 2);
        //if the binarybyte is not 8 characters long, its not a proper result
        while(binarybyte.Length < 8)
        {
            //prepend the value with a 0
            binarybyte = "0" + binarybyte;
        }
        //append the binarybyte to the result
        result += binarybyte;
    }
    //return the result
    return result;
}

With Yglu Structural Templating, your example can be written:

  !apply .foo: 
    propname: "some_prop"
    default: "some default"

"Headers already sent" means that your PHP script already sent the HTTP headers, and as such it can't make modifications to them now.

Check that you don't send ANY content before calling session_start. Better yet, just make session_start the first thing you do in your PHP file (so put it at the absolute beginning, before all HTML etc).

Are you sure that your configuration file (web.config) is at the right place and the connection string is really in the (generated) file? If you publish your file, the content of web.release.config might be copied.

The configuration and the access to the Connection string looks all right to me. I would always add a providername

<connectionStrings>
  <add name="Dbconnection" 
       connectionString="Server=localhost; Database=OnlineShopping; 
       Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>

You could possibly set a cookie at an expiration date of a month or something and then reassign the cookie every time the user visits the website again

This is an extremely broad scope question, and a lot of the pros/cons will be contextual to the situation.

In all cases, these storage mechanisms will be specific to an individual browser on an individual computer/device. Any requirement to store data on an ongoing basis across sessions will need to involve your application server side - most likely using a database, but possibly XML or a text/CSV file.

localStorage, sessionStorage, and cookies are all client storage solutions. Session data is held on the server where it remains under your direct control.

localStorage and sessionStorage

localStorage and sessionStorage are relatively new APIs (meaning, not all legacy browsers will support them) and are near identical (both in APIs and capabilities) with the sole exception of persistence. sessionStorage (as the name suggests) is only available for the duration of the browser session (and is deleted when the tab or window is closed) - it does, however, survive page reloads (source DOM Storage guide - Mozilla Developer Network).

Clearly, if the data you are storing needs to be available on an ongoing basis then localStorage is preferable to sessionStorage - although you should note both can be cleared by the user so you should not rely on the continuing existence of data in either case.

localStorage and sessionStorage are perfect for persisting non-sensitive data needed within client scripts between pages (for example: preferences, scores in games). The data stored in localStorage and sessionStorage can easily be read or changed from within the client/browser so should not be relied upon for storage of sensitive or security-related data within applications.

Cookies

This is also true for cookies, these can be trivially tampered with by the user, and data can also be read from them in plain text - so if you are wanting to store sensitive data then the session is really your only option. If you are not using SSL, cookie information can also be intercepted in transit, especially on an open wifi.

On the positive side cookies can have a degree of protection applied from security risks like Cross-Site Scripting (XSS)/Script injection by setting an HTTP only flag which means modern (supporting) browsers will prevent access to the cookies and values from JavaScript (this will also prevent your own, legitimate, JavaScript from accessing them). This is especially important with authentication cookies, which are used to store a token containing details of the user who is logged on - if you have a copy of that cookie then for all intents and purposes you become that user as far as the web application is concerned, and have the same access to data and functionality the user has.

As cookies are used for authentication purposes and persistence of user data, all cookies valid for a page are sent from the browser to the server for every request to the same domain - this includes the original page request, any subsequent Ajax requests, all images, stylesheets, scripts, and fonts. For this reason, cookies should not be used to store large amounts of information. The browser may also impose limits on the size of information that can be stored in cookies. Typically cookies are used to store identifying tokens for authentication, session, and advertising tracking. The tokens are typically not human readable information in and of themselves, but encrypted identifiers linked to your application or database.

localStorage vs. sessionStorage vs. Cookies

In terms of capabilities, cookies, sessionStorage, and localStorage only allow you to store strings - it is possible to implicitly convert primitive values when setting (these will need to be converted back to use them as their type after reading) but not Objects or Arrays (it is possible to JSON serialise them to store them using the APIs). Session storage will generally allow you to store any primitives or objects supported by your Server Side language/framework.

Client-side vs. Server-side

As HTTP is a stateless protocol - web applications have no way of identifying a user from previous visits on returning to the web site - session data usually relies on a cookie token to identify the user for repeat visits (although rarely URL parameters may be used for the same purpose). Data will usually have a sliding expiry time (renewed each time the user visits), and depending on your server/framework data will either be stored in-process (meaning data will be lost if the web server crashes or is restarted) or externally in a state server or database. This is also necessary when using a web-farm (more than one server for a given website).

As session data is completely controlled by your application (server side) it is the best place for anything sensitive or secure in nature.

The obvious disadvantage of server-side data is scalability - server resources are required for each user for the duration of the session, and that any data needed client side must be sent with each request. As the server has no way of knowing if a user navigates to another site or closes their browser, session data must expire after a given time to avoid all server resources being taken up by abandoned sessions. When using session data you should, therefore, be aware of the possibility that data will have expired and been lost, especially on pages with long forms. It will also be lost if the user deletes their cookies or switches browsers/devices.

Some web frameworks/developers use hidden HTML inputs to persist data from one page of a form to another to avoid session expiration.

localStorage, sessionStorage, and cookies are all subject to "same-origin" rules which means browsers should prevent access to the data except the domain that set the information to start with.

Show them that the base-10 system suffers from exactly the same problem.

Try to represent 1/3 as a decimal representation in base 10. You won't be able to do it exactly.

So if you write "0.3333", you will have a reasonably exact representation for many use cases.

But if you move that back to a fraction, you will get "3333/10000", which is not the same as "1/3".

Other fractions, such as 1/2 can easily be represented by a finite decimal representation in base-10: "0.5"

Now base-2 and base-10 suffer from essentially the same problem: both have some numbers that they can't represent exactly.

While base-10 has no problem representing 1/10 as "0.1" in base-2 you'd need an infinite representation starting with "0.000110011..".

char* str = "HELLO";
char c = str[1];

Keep in mind that arrays and strings in C begin indexing at 0 rather than 1, so "H" is str[0], "E" is str[1], the first "L" is str[2] and so on.

May you should try creating a temp string object and then add to existing item string. Something like this.

for(int k=0; k<bufferPos; k++){
      item += String(buffer[k]);
      }

TypeScript 0.9+ has a specification for enums:

enum AnimationType {
    BOUNCE,
    DROP,
}

The final comma is optional.

If you check out this webpage, 15 different ways of doing this are benchmarked, including using parallel loops.

The fastest way appears to be using either a single threaded for-loop (if you have .Net version < 4.0) or a parallel.for loop (if using .Net > 4.0 with thousands of checks).

Assuming "ss" is your Search String, "ch" is your character array (if you have more than one char you're looking for), here's the basic gist of the code that had the fastest run time single threaded:

for (int x = 0; x < ss.Length; x++)
{
    for (int y = 0; y < ch.Length; y++)
    {
        for (int a = 0; a < ss[x].Length; a++ )
        {
        if (ss[x][a] == ch[y])
            //it's found. DO what you need to here.
        }
    }
}

The benchmark source code is provided too so you can run your own tests.

The pickle Python library implements binary protocols for serializing and de-serializing a Python object.

When you import torch (or when you use PyTorch) it will import pickle for you and you don't need to call pickle.dump() and pickle.load() directly, which are the methods to save and to load the object.

In fact, torch.save() and torch.load() will wrap pickle.dump() and pickle.load() for you.

A state_dict the other answer mentioned deserves just few more notes.

What state_dict do we have inside PyTorch? There are actually two state_dicts.

The PyTorch model is torch.nn.Module has model.parameters() call to get learnable parameters (w and b). These learnable parameters, once randomly set, will update over time as we learn. Learnable parameters are the first state_dict.

The second state_dict is the optimizer state dict. You recall that the optimizer is used to improve our learnable parameters. But the optimizer state_dict is fixed. Nothing to learn in there.

Because state_dict objects are Python dictionaries, they can be easily saved, updated, altered, and restored, adding a great deal of modularity to PyTorch models and optimizers.

Let's create a super simple model to explain this:

import torch
import torch.optim as optim

model = torch.nn.Linear(5, 2)

# Initialize optimizer
optimizer = optim.SGD(model.parameters(), lr=0.001, momentum=0.9)

print("Model's state_dict:")
for param_tensor in model.state_dict():
    print(param_tensor, "\t", model.state_dict()[param_tensor].size())

print("Model weight:")    
print(model.weight)

print("Model bias:")    
print(model.bias)

print("---")
print("Optimizer's state_dict:")
for var_name in optimizer.state_dict():
    print(var_name, "\t", optimizer.state_dict()[var_name])

This code will output the following:

Model's state_dict:
weight   torch.Size([2, 5])
bias     torch.Size([2])
Model weight:
Parameter containing:
tensor([[ 0.1328,  0.1360,  0.1553, -0.1838, -0.0316],
        [ 0.0479,  0.1760,  0.1712,  0.2244,  0.1408]], requires_grad=True)
Model bias:
Parameter containing:
tensor([ 0.4112, -0.0733], requires_grad=True)
---
Optimizer's state_dict:
state    {}
param_groups     [{'lr': 0.001, 'momentum': 0.9, 'dampening': 0, 'weight_decay': 0, 'nesterov': False, 'params': [140695321443856, 140695321443928]}]

Note this is a minimal model. You may try to add stack of sequential

model = torch.nn.Sequential(
          torch.nn.Linear(D_in, H),
          torch.nn.Conv2d(A, B, C)
          torch.nn.Linear(H, D_out),
        )

Note that only layers with learnable parameters (convolutional layers, linear layers, etc.) and registered buffers (batchnorm layers) have entries in the model's state_dict.

Non learnable things, belong to the optimizer object state_dict, which contains information about the optimizer's state, as well as the hyperparameters used.

The rest of the story is the same; in the inference phase (this is a phase when we use the model after training) for predicting; we do predict based on the parameters we learned. So for the inference, we just need to save the parameters model.state_dict().

torch.save(model.state_dict(), filepath)

And to use later model.load_state_dict(torch.load(filepath)) model.eval()

Note: Don't forget the last line model.eval() this is crucial after loading the model.

Also don't try to save torch.save(model.parameters(), filepath). The model.parameters() is just the generator object.

On the other side, torch.save(model, filepath) saves the model object itself, but keep in mind the model doesn't have the optimizer's state_dict. Check the other excellent answer by @Jadiel de Armas to save the optimizer's state dict.

For long response bodies (and various other similar situations), the solution I use is always to pipe to less, so

curl -i https://api.github.com/users | less

or

curl -s -D - https://api.github.com/users | less

will do the job.

Remove existing origin and add new origin to your project directory

>$ git remote show origin

>$ git remote rm origin

>$ git add .

>$ git commit -m "First commit"

>$ git remote add origin Copied_origin_url

>$ git remote show origin

>$ git push origin master

From Activity you send data with Bundle as:

Bundle bundle = new Bundle();
bundle.putString("data", "Data you want to send");

// Your fragment
MyFragment obj = new MyFragment();
obj.setArguments(bundle);

And in Fragment onCreateView method get the data:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
{
    String data = getArguments().getString("data");// data which sent from activity  
    return inflater.inflate(R.layout.myfragment, container, false);
}

For those who still might be facing issue adding jsx to test fixed it for me

test: /\.jsx?$/,

You can't select a sheet in a non-active workbook.

You must first activate the workbook, then you can select the sheet.

workbooks("A").activate
workbooks("A").worksheets("B").select 

When you use Activate it automatically activates the workbook.

Note you can select >1 sheet in a workbook:

activeworkbook.sheets(array("sheet1","sheet3")).select

but only one sheet can be Active, and if you activate a sheet which is not part of a multi-sheet selection then those other sheets will become un-selected.

I'm using output parameter in SQL Proc and later I used this values in resultset.

One more way assume branch1 - is branch with committed changes branch2 - is desirable branch

git fetch && git checkout branch1
git log

select commit ids that you need to move

git fetch && git checkout branch2
git cherry-pick commit_id_first..commit_id_last
git push

Now revert unpushed commits from initial branch

git fetch && git checkout branch1
git reset --soft HEAD~1

You can set the calendar to use only AM or PM using

calendar.set(Calendar.AM_PM, int);

0 = AM

1 = PM

Hope this helps

Currently there is no production ready HTML5 only solution for recording video over the web. The current available solutions are as follows:

HTML Media Capture

Works on mobile devices and uses the OS' video capture app to capture video and upload/POST it to a web server. You will get .mov files on iOS (these are unplayable on Android I've tried) and .mp4 and .3gp on Android. At least the codecs will be the same: H.264 for video and AAC for audio in 99% of the devices.

Image courtesy of https://addpipe.com/blog/the-new-video-recording-prompt-for-media-capture-in-ios9/

Flash and a media server on desktop.

Video recording in Flash works like this: audio and video data is captured from the webcam and microphone, it's encoded using Sorenson Spark or H.264 (video) and Nellymoser Asao or Speex (audio) then it's streamed (rtmp) to a media server (Red5, AMS, Wowza) where it is saved in .flv or .f4v files.

The MediaStream Recording proposal

The MediaStream Recording is a proposal by the the Media Capture Task Force (a joint task force between the WebRTC and Device APIs working groups) for a JS API who's purpose is to make basic video recording in the browser very simple.

Not supported by major browsers. When it'll get implemented (if it will) you will most probably end up with different filetypes (at least .ogg and .webm) and audio/video codecs depending on the browser.

Commercial solutions

There are a few saas and software solutions out there that will handle some or all of the above including addpipe.com, HDFVR, Nimbb and Cameratag.

Further reading:

• HTML Media Capture video recording prompts in iOS9
• HTML5 Video Recording covers both HTML Media Capture and MediaStream Recording.
• Pipe is a saas for video recording that also handles the final conversion to .mp4

If you want to throw an exception from the catch block you must inform your method/class/etc. that it needs to throw said exception. Like so:

public void doStuff() throws MyException {
    try {
        //Stuff
    } catch(StuffException e) {
        throw new MyException();
    }
}

And now your compiler will not yell at you :)

There are no hard and fast rules, but the rule of thumb from a purely conceptual standpoint that I like to use can briefly be summed up like this: a URI path (by definition) represents a resource and query parameters are essentially modifiers on that resource. So far that likely doesn't help... With a REST API you have the major methods of acting upon a single resource using GET, PUT, and DELETE . Therefore whether something should be represented in the path or as a parameter can be reduced to whether those methods make sense for the representation in question. Would you reasonably PUT something at that path and would it be semantically sound to do so? You could of course PUT something just about anywhere and bend the back-end to handle it, but you should be PUTing what amounts to a representation of the actual resource and not some needlessly contextualized version of it. For collections the same can be done with POST. If you wanted to add to a particular collection what would be a URL that makes sense to POST to.

This still leaves some gray areas as some paths could point to what amount to children of parent resources which is somewhat discretionary and dependent on their use. The one hard line that this draws is that any type of transitive representation should be done using a query parameter, since it would not have an underlying resource.

In response to the real world example given in the original question (Twitter's API), the parameters represent a transitive query that filters on the state of the resources (rather than a hierarchy). In that particular example it would be entirely unreasonable to add to the collection represented by those constraints, and further that query would not be able to be represented as a path that would make any sense in the terms of an object graph.

The adoption of this type of resource oriented perspective can easily map directly to the object graph of your domain model and drive the logic of your API to the point where everything works very cleanly and in a fairly self-documenting way once it snaps into clarity. The concept can also be made clearer by stepping away from systems that use traditional URL routing mapped on to a normally ill-fitting data model (i.e. an RDBMS). Apache Sling would certainly be a good place to start. The concept of object traversal dispatch in a system like Zope also provides a clearer analog.

foreach ($basearr as &$row)
{
    $row['value'] = $row['url'];
    unset( $row['url'] );
}

unset($row);

You actually do not have to wait a full second for each request. I found that if I wait 200 miliseconds between each request I am able to avoid the OVER_QUERY_LIMIT response and the user experience is passable. With this solution you can load 20 items in 4 seconds.

$(items).each(function(i, item){

  setTimeout(function(){

    geoLocate("my address", function(myLatlng){
      ...
    });

  }, 200 * i);

}

I did the following and it seems to work (even in iOS 8):

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {

        [[UIApplication sharedApplication] setStatusBarHidden:YES];
    }
}

- (BOOL)prefersStatusBarHidden {
    return YES;
}

We can directly subtract dates to get difference in Days.

    SET SERVEROUTPUT ON ;
    DECLARE
        V_VAR NUMBER;
    BEGIN
         V_VAR:=TO_DATE('2000-01-02', 'YYYY-MM-DD') - TO_DATE('2000-01-01', 'YYYY-MM-DD') ;
         DBMS_OUTPUT.PUT_LINE(V_VAR);
    END;

bootstrap 3 + jquery 2.0.3:

$('#myModal').on('hide.bs.modal', function () {
   $('#myModal').removeData();
})

This is an improved version of the one above... considering that you want age to be an 'int'. because sometimes you don't want to fill your program with a bunch of libraries.

public int getAge(Date dateOfBirth) {
    int age = 0;
    Calendar born = Calendar.getInstance();
    Calendar now = Calendar.getInstance();
    if(dateOfBirth!= null) {
        now.setTime(new Date());
        born.setTime(dateOfBirth);  
        if(born.after(now)) {
            throw new IllegalArgumentException("Can't be born in the future");
        }
        age = now.get(Calendar.YEAR) - born.get(Calendar.YEAR);             
        if(now.get(Calendar.DAY_OF_YEAR) < born.get(Calendar.DAY_OF_YEAR))  {
            age-=1;
        }
    }  
    return age;
}

This query here will list the total size that a table takes up - clustered index, heap and all nonclustered indices:

SELECT 
    s.Name AS SchemaName,
    t.NAME AS TableName,
    p.rows AS RowCounts,
    SUM(a.total_pages) * 8 AS TotalSpaceKB, 
    SUM(a.used_pages) * 8 AS UsedSpaceKB, 
    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM 
    sys.tables t
INNER JOIN 
    sys.schemas s ON s.schema_id = t.schema_id
INNER JOIN      
    sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN 
    sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN 
    sys.allocation_units a ON p.partition_id = a.container_id
WHERE 
    t.NAME NOT LIKE 'dt%'    -- filter out system tables for diagramming
    AND t.is_ms_shipped = 0
    AND i.OBJECT_ID > 255 
GROUP BY 
    t.Name, s.Name, p.Rows
ORDER BY 
    s.Name, t.Name

If you want to separate table space from index space, you need to use AND i.index_id IN (0,1) for the table space (index_id = 0 is the heap space, index_id = 1 is the size of the clustered index = data pages) and AND i.index_id > 1 for the index-only space

Include this code somewhere when you slide to your 'section' called blog.

$("#myLink").click(function() {
    setTimeout(function() {
        window.navigate("the url of the page you want to navigate back to");
    }, 2000);
});

Where myLink is the id of your href.

You can handle loading the excel file content by writing Java code using Apache POI library (https://poi.apache.org/). The library is developed for working with MS office application data including Excel.

I have recently created the application based on the technology that will help you to load Excel files to the Postgres database. The application is available under http://www.abespalov.com/. The application is tested only for Windows, but should work for Linux as well.

The application automatically creates necessary tables with the same columns as in the Excel files and populate the tables with content. You can export several files in parallel. You can skip the step to convert the files into the CSV format. The application handles the xls and xlsx formats.

Overall application stages are :

1. Load the excel file content. Here is the code depending on file extension:

{

fileExtension = FilenameUtils.getExtension(inputSheetFile.getName());
    if (fileExtension.equalsIgnoreCase("xlsx")) {
        workbook = createWorkbook(openOPCPackage(inputSheetFile));
    } else {
        workbook =     
        createWorkbook(openNPOIFSFileSystemPackage(inputSheetFile));
    }

sheet = workbook.getSheetAt(0);

}

2. Establish Postgres JDBC connection
3. Create a Postgres table
4. Iterate over the sheet and inset rows into the table. Here is a piece of Java code :

{

Iterator<Row> rowIterator = InitInputFilesImpl.sheet.rowIterator();

//skip a header
if (rowIterator.hasNext()) {
    rowIterator.next();
}
while (rowIterator.hasNext()) {
    Row row = (Row) rowIterator.next();
    // inserting rows
}

Here you can find all Java code for the application created for exporting excel to Postgres (https://github.com/palych-piter/Excel2DB).

In my case the host requires TLS 1.2 so needed to enforce using the crypto_method ssl param.

$client = new SoapClient($wsdl,
    array(
           'location' => $location,
           'keep_alive' => false,
           "stream_context" => stream_context_create([
                'ssl' => [
                    'crypto_method' =>  STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT,
                ]
            ]),
           'trace' => 1, // used for debug
        )
    );

This was bothering me for a while with GMaps v3.

I found a way to do it like this:

google.maps.event.addListenerOnce(map, 'idle', function(){
    // do something only the first time the map is loaded
});

The "idle" event is triggered when the map goes to idle state - everything loaded (or failed to load). I found it to be more reliable then tilesloaded/bounds_changed and using addListenerOnce method the code in the closure is executed the first time "idle" is fired and then the event is detached.

See also the events section in the Google Maps Reference.

Regarding your second question about properties, you can use self.myView only if you declared it as a property in class. Since myView is a local variable, you can not use it that way. For more details on this, I would recommend you to go through the apple documentation on Declared Properties,

Call

setSupportActionBar(toolbar)

inside

onViewCreated(...) 

of Fragment

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
    ((MainActivity)getActivity()).setSupportActionBar(toolbar);
    setHasOptionsMenu(true);
}

Simply Use EditText.setFocusable(false); in activity

or use in xml

android:focusable="false"

Ok here's how I fixed this

My model is a list of categories. Each category contains a list of its subcategories.
with this in mind, every time in the foreach loop, each RadioButton will have its category's ID (which is unique) as its name attribue.
And I also used Html.RadioButton instead of Html.RadioButtonFor.

Here's the final 'working' pseudo-code:

@foreach (var cat in Model.Categories)
{
  //A piece of code & html here
  @foreach (var item in cat.SubCategories)
  {
     @Html.RadioButton(item.CategoryID.ToString(), item.ID)
  }    
}

The result is:

<input name="127" type="radio" value="110">

Please note that I HAVE NOT put all these radio button groups inside a form. And I don't know if this solution will still work properly in a form.

Thanks to all of the people who helped me solve this ;)

Another answer for the first question is to use one for loop and perform linear indexing into the array using the function NUMEL to get the total number of elements:

total = 0;
for i = 1:numel(A)
  total = total+A(i);
end

It may help you understand loops by implementing yourself. See Bubble sort is easy to understand:

public void bubbleSort(int[] array) {
    boolean swapped = true;
    int j = 0;
    int tmp;
    while (swapped) {
        swapped = false;
        j++;
        for (int i = 0; i < array.length - j; i++) {
            if (array[i] > array[i + 1]) {
                tmp = array[i];
                array[i] = array[i + 1];
                array[i + 1] = tmp;
                swapped = true;
            }
        }
    }
}

Of course, you should not use it in production as there are better performing algorithms for large lists such as QuickSort or MergeSort which are implemented by Arrays.sort(array)

In my case i have multiple sections and both the section and row index is vital, so in such a case i just created a property on UIButton which i set the cell indexPath like so:

fileprivate struct AssociatedKeys {
    static var index = 0
}

extension UIButton {

    var indexPath: IndexPath? {
        get {
            return objc_getAssociatedObject(self, &AssociatedKeys.index) as? IndexPath
        }
        set {
            objc_setAssociatedObject(self, &AssociatedKeys.index, newValue, .OBJC_ASSOCIATION_RETAIN_NONATOMIC)
        }
    }
}

Then set the property in cellForRowAt like this :

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell") as! Cell
    cell.button.indexPath = indexPath
}

Then in the handleTapAction you can get the indexPath like this :

@objc func handleTapAction(_ sender: UIButton) {
    self.selectedIndex = sender.indexPath

}

And another one:

cd  /path/to/pdf
printf "%s\0" *.[Pp][Dd][Ff] | xargs -0 rm

printf is a shell builtin, and as far as I know it's always been as such. Now given that printf is not a shell command (but a builtin), it's not subject to "argument list too long ..." fatal error.

So we can safely use it with shell globbing patterns such as *.[Pp][Dd][Ff], then we pipe its output to remove (rm) command, through xargs, which makes sure it fits enough file names in the command line so as not to fail the rm command, which is a shell command.

The \0 in printf serves as a null separator for the file names wich are then processed by xargs command, using it (-0) as a separator, so rm does not fail when there are white spaces or other special characters in the file names.

1. Make sure markup (svc) file has service attribute with namespace.classname and codebehind will be classname.svc.cs

2. Rebuild the solution

3. Restart the app pools from local IIS once.

The answer is due to the fact that Google Chrome uses an SQLite file to save cookies. It resides under:

C:\Users\<your_username>\AppData\Local\Google\Chrome\User Data\Default\

inside Cookies file. (which is an SQLite database file)

So it's not a file stored on hard drive but a row in an SQLite database file which can be read by a third party program such as: SQLite Database Browser

EDIT: Thanks to @Chexpir, it is also good to know that the values are stored encrypted.

The Maven Dependency Plugin will help, especially the dependency:analyze goal:

dependency:analyze analyzes the dependencies of this project and determines which are: used and declared; used and undeclared; unused and declared.

Another thing that might help to do some cleanup is the Dependency Convergence report from the Maven Project Info Reports Plugin.

Use this code:

internal void SomeFunction() {
    Dictionary<string, string> formField = new Dictionary<string, string>();
    
    formField.Add("Name", "Henry");
    formField.Add("Age", "21");
    
    string body = GetBodyStringFromDictionary(formField);
    // output : Name=Henry&Age=21
}

internal string GetBodyStringFromDictionary(Dictionary<string, string> formField)
{
    string body = string.Empty;
    foreach (var pair in formField)
    {
        body += $"{pair.Key}={pair.Value}&";   
    }

    // delete last "&"
    body = body.Substring(0, body.Length - 1);

    return body;
}

This code will open the menu in question, and will setup a click listener event. When triggered it will loop through the target id's parents until it finds the menu id. If it doesn't, it will hide the menu because the user has clicked outside the menu. I've tested it and it works.

function tog_alerts(){
   if($('#Element').css('display') == 'none'){
       $('#Element').show();
       setTimeout(function () {
           document.body.addEventListener('click', Close_Alerts, false);
       }, 500);
   }
}

function Close_Alerts(e){
   var current = e.target;
   var check = 0;
   while (current.parentNode){
      current = current.parentNode
      if(current.id == 'Element'){
         check = 1;
      }
   }
   if(check == 0){
      document.body.removeEventListener('click', Close_Alerts, false);
      $('#Element').hide();         
   }
}

I wrote recently a simple function which removes excess white space from string without regular expression implode(' ', array_filter(explode(' ', $str))).

No, it sets all members/elements that haven't been explicitly set to their default-initialisation value, which is zero for numeric types.

I had to cast the integer equivalent to get around the fact that I'm still using .NET 4.0

System.Net.ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;
/* Note the property type  
   [System.Flags]
   public enum SecurityProtocolType
   {
     Ssl3 = 48,
     Tls = 192,
     Tls11 = 768,
     Tls12 = 3072,
   } 
*/

Do whatever you want as long as its minimal, consistent, and doesn't break any rules.

Personally, I find the Boost style easiest; it matches the standard library (giving a uniform look to code) and is simple. I personally tack on m and p prefixes to members and parameters, respectively, giving:

                single_statements(); // don't need braces

            for (size_t i = 0; i < 100; ++i)
            {
                but_multiple(i);
                statements_do();
            }             
        }

        const complex_type& value() const
        {
            return mValue; // no conflict with value here
        }

        void value(const complex_type& pValue)
        {
            mValue = pValue ; // or here
        }

What you need to realize, coming from CVS, is that you no longer create directories when setting up a branch.
No more "sticky tag" (which can be applied to just one file), or "branch tag".
Branch and tags are two different objects in Git, and they always apply to the all repo.

You would no longer (with SVN this time) have to explicitly structure your repository with:

branches
   myFirstBranch
     myProject
       mySubDirs
   mySecondBranch
     ...
tags
   myFirstTag
     myProject
       mySubDirs
   mySecondTag
   ...

That structure comes from the fact CVS is a revision system and not a version system (see Source control vs. Revision Control?).
That means branches are emulated through tags for CVS, directory copies for SVN.

Your question makes senses if you are used to checkout a tag, and start working in it.
Which you shouldn't ;)
A tag is supposed to represent an immutable content, used only to access it with the guarantee to get the same content every time.

In Git, the history of revisions is a series of commits, forming a graph.
A branch is one path of that graph

x--x--x--x--x # one branch
    \ 
     --y----y # another branch
       1.1
        ^
        |
        # a tag pointing to a commit

• If you checkout a tag, you will need to create a branch to start working from it.
• If you checkout a branch, you will directly see the latest commit it('HEAD') of that branch.

See Jakub Narebski's answer for all the technicalities, but frankly, at this point, you do not need (yet) all the details ;)

The main point is: a tag being a simple pointer to a commit, you will never be able to modify its content. You need a branch.

In your case, each developer working on a specific feature:

• should create their own branch in their respective repository
• track branches from their colleague's repositories (the one working on the same feature)
• pulling/pushing in order to share your work with your peers.

Instead of tracking directly the branches of your colleagues, you could track only the branch of one "official" central repository to which everyone pushes his/her work in order to integrate and share everyone's work for this particular feature.

From the "Text Contains" dropdown menu select "Custom formula is:", and write: "=countif(A:A, A1) > 1" (without the quotes)

I did exactly as zolley proposed, but there should be done small correction: use "Custom formula is" instead of "Text Contains". And then conditional rendering will work.

$selectElement.select2({
    minimumResultsForSearch: -1,
    placeholder: 'SelectRelatives'}).on('select2-opening', function() {                                                                       $(this).closest('li').find('input').attr('placeholder','Select Relative');                            
});

html:

<input type="text" class="datepick" id="date_1" />
<input type="text" class="datepick" id="date_2" />
<input type="text" class="datepick" id="date_3" />

script:

$('.datepick').each(function(){
    $(this).datepicker();
});

(pseudo coded up a bit to keep it simpler)

When an element, such as a div is floated, its parent container no longer considers its height, i.e.

<div id="main">
  <div id="child" style="float:left;height:40px;"> Hi</div>
</div>

The parent container will not be be 40 pixels tall by default. This causes a lot of weird little quirks if you're using these containers to structure layout.

So the clearfix class that various frameworks use fixes this problem by making the parent container "acknowledge" the contained elements.

Day to day, I normally just use frameworks such as 960gs, Twitter Bootstrap for laying out and not bothering with the exact mechanics.

using : New Java 7 NIO library, try

        if(!Files.exists(filePath.getParent())) {
            Files.createDirectory(filePath.getParent());
        }
        if(!Files.exists(filePath)) {

        // Empty the file content
        writer = Files.newBufferedWriter(filePath);
        writer.write("");
        writer.flush();

The above code checks if Directoty exist if not creates the directory, checks if file exists is yes it writes empty string and flushes the buffer, in the end yo get the writer pointing to empty file

You can solve this problem in different way.

If you use Row/Column then you have to use mainAxisAlignment: MainAxisAlignment.spaceEvenly

If you use Wrap Widget you have to use runSpacing: 5, spacing: 10,

In anywhere you can use SizeBox()

I'm guessing you get the error on accessing audioSounds and minTime, right?

The problem is you can't access instance members from static methods. What this means is that, a static method is a method that exists only once and can be used by all other objects (if its access modifier permits it).

Instance members, on the other hand, are created for every instance of the object. So if you create ten instances, how would the runtime know out of all these instances, which audioSounds list it should access?

Like others said, make your audioSounds and minTime static, or you could make your method an instance method, if your design permits it.

Before you can use your key with GitHub, follow this step in the tutorial, Testing your SSH connection:

The another solution is service volume, You can define a service volume and mount host's PostgreSQL Data directory in that volume. Check out the given compose file for details.

version: '2'
services:
  db:   
    image: postgres:9.6.1
    volumes:
      - "/var/lib/postgresql/data:/var/lib/postgresql/data" 
    ports:
      - "5432:5432"

By doing this, another PostgreSQL service will run under container but uses same data directory which host PostgreSQL service is using.

Try:

git remote prune origin

From the Git remote documentation:

prune

Deletes all stale remote-tracking branches under <name>. These stale branches have already been removed from the remote repository referenced by <name>, but are still locally available in "remotes/<name>".

With --dry-run option, report what branches will be pruned, but do not actually prune them.

Ok a few things: gets is unsafe and should be replaced with fgets(input, sizeof(input), stdin) so that you don't get a buffer overflow.

Next, to compare strings, you must use strcmp, where a return value of 0 indicates that the two strings match. Using the equality operators (ie. !=) compares the address of the two strings, as opposed to the individual chars inside them.

And also note that, while in this example it won't cause a problem, fgets stores the newline character, '\n' in the buffers also; gets() does not. If you compared the user input from fgets() to a string literal such as "abc" it would never match (unless the buffer was too small so that the '\n' wouldn't fit in it).

Select * from myTable m
where m.status not like 'Done%'

There are two common ways of doing that with built-in JSON serializers:

1. JavaScriptSerializer

   var serializer = new JavaScriptSerializer();
   return serializer.Serialize(TheList);
   

2. DataContractJsonSerializer

   var serializer = new DataContractJsonSerializer(TheList.GetType());
   using (var stream = new MemoryStream())
   {
       serializer.WriteObject(stream, TheList);
       using (var sr = new StreamReader(stream))
       {
           return sr.ReadToEnd();
       }
   }
   

   Note, that this option requires definition of a data contract for your class:

   [DataContract]
   public class MyObjectInJson
   {
      [DataMember]
      public long ObjectID {get;set;}
      [DataMember]
      public string ObjectInJson {get;set;}
   }
   

Atom currently does not have a built-in terminal(that I know of), so you would have to install an additional package such as platformio-ide-terminal.

The following screenshots were taken on a mac.

1. Click on Atom and select Preferences
   
   
   
   
2. In the Settings tab that appears, click on the add icon + to Install a new package
   
   
   
   
3. A search bar will appear. Most packages should have the feature you desire in their name, so you can begin to type those keywords to see suggestions. In this case if you already know the name, just enter it there
   
   
   
   
4. Click Install

if and grep -Eq

arg='abc'
if echo "$arg" | grep -Eq 'a.c|d.*'; then
  echo 'first'
elif echo "$arg" | grep -Eq 'a{2,3}'; then
  echo 'second'
fi

where:

• -q prevents grep from producing output, it just produces the exit status
• -E enables extended regular expressions

I like this because:

• it is POSIX 7
• it supports extended regular expressions, unlike POSIX case
• the syntax is less clunky than case statements when there are few cases

One downside is that this is likely slower than case since it calls an external grep program, but I tend to consider performance last when using Bash.

case is POSIX 7

Bash appears to follow POSIX by default without shopt as mentioned by https://stackoverflow.com/a/4555979/895245

Here is the quote: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_01 section "Case Conditional Construct":

The conditional construct case shall execute the compound-list corresponding to the first one of several patterns (see Pattern Matching Notation) [...] Multiple patterns with the same compound-list shall be delimited by the '|' symbol. [...]

The format for the case construct is as follows:

case word in
     [(] pattern1 ) compound-list ;;
     [[(] pattern[ | pattern] ... ) compound-list ;;] ...
     [[(] pattern[ | pattern] ... ) compound-list]
  esac

and then http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_13 section "2.13. Pattern Matching Notation" only mentions ?, * and [].

An abstract function is "just" a signature, without an implementation. It is used in an interface to declare how the class can be used. It must be implemented in one of the derived classes.

Virtual function (method actually), is a function you declare as well, and should implemented in one of the inheritance hierarchy classes.

The inherited instances of such class, inherit the implementation as well, unless you implement it, in a lower hierarchy class.

foreach ( int number in numbers )
{
    if ( number < 0 )
    {
        continue;
    }

    //otherwise process number
}

This worked for me (using jQuery 2.1)

$(document).ajaxSend(function(elm, xhr, s){
    if (s.type == "POST") {
        s.data += s.data?"&":"";
        s.data += "_token=" + $('#csrf-token').val();
    }
});

or this:

$(document).ajaxSend(function(elm, xhr, s){
    if (s.type == "POST") {
        xhr.setRequestHeader('x-csrf-token', $('#csrf-token').val());
    }
});

(where #csrf-token is the element containing the token)

This kind of thing is not easy. Here is a method that calls a static method:

public static Object callStaticMethod(
    // class that contains the static method
    final Class<?> clazz,
    // method name
    final String methodName,
    // optional method parameters
    final Object... parameters) throws Exception{
    for(final Method method : clazz.getMethods()){
        if(method.getName().equals(methodName)){
            final Class<?>[] paramTypes = method.getParameterTypes();
            if(parameters.length != paramTypes.length){
                continue;
            }
            boolean compatible = true;
            for(int i = 0; i < paramTypes.length; i++){
                final Class<?> paramType = paramTypes[i];
                final Object param = parameters[i];
                if(param != null && !paramType.isInstance(param)){
                    compatible = false;
                    break;
                }

            }
            if(compatible){
                return method.invoke(/* static invocation */null,
                    parameters);
            }
        }
    }
    throw new NoSuchMethodException(methodName);
}

Update: Wait, I just saw the gwt tag on the question. You can't use reflection in GWT

You can use Environment Injector Plugin to set environment variables in Jenkins at job and node levels. Below I will show how to set them at job level.

1. From the Jenkins web interface, go to Manage Jenkins > Manage Plugins and install the plugin.

2. Go to your job Configure screen
3. Find Add build step in Build section and select Inject environment variables
4. Set the desired environment variable as VARIABLE_NAME=VALUE pattern. In my case, I changed value of USERPROFILE variable

If you need to define a new environment variable depending on some conditions (e.g. job parameters), then you can refer to this answer.

    dbc.Employees.Add(emptbl);           // pass the table object 
    dbc.SaveChanges();

    return View();

• React Native is an open-source mobile application framework.
• React JS is front-end javascript library it's large library not a framework.

Map.Entry is a key and its value combined into one class. This allows you to iterate over Map.entrySet() instead of having to iterate over Map.keySet(), then getting the value for each key. A better way to write what you have is:

for (Map.Entry<String, JButton> entry : listbouton.entrySet())
{
  String key = entry.getKey();
  JButton value = entry.getValue();

  this.add(value);
}

You have to increase client_max_body_size in nginx.conf file. This is the basic step. But if your backend laravel then you have to do some changes in the php.ini file as well. It depends on your backend. Below I mentioned file location and condition name.

sudo vim /etc/nginx/nginx.conf.

After open the file adds this into HTTP section.

client_max_body_size 100M;

Why use a dropdown at all? The only way the user will see your explanatory text is by blindly hovering over one of the options.

I think it would be preferable to use a radio button group, and next to each item, put a tooltip icon indicating additional information, as well as displaying it after selection (like you currently have it).

I realize this doesn't exactly solve your problem, but I don't see the point in struggling with an html element that's notorious for its inflexibility when you could just use one that's better suited in the first place.

Something like that maybe?

<form>
  <input id="fileinput" type="file" style="display:none;"/>
</form>
<button id="falseinput">El Cucaratcha, for example</button>
<span id="selected_filename">No file selected</span>

<script>
$(document).ready( function() {
  $('#falseinput').click(function(){
    $("#fileinput").click();
  });
});
$('#fileinput').change(function() {
  $('#selected_filename').text($('#fileinput')[0].files[0].name);
});

</script>

I found an issue with Diagram and Schema in SQL-Server 2016 that could be useful to the subject. I was editing diagram (related to, and with lot of tables of, the "sales" schema) and added a new table, BUT forgot to declare it schema, so it was with the default "dbo". Then when I returned to, and opened up, the schema "sales" and tried to add an existent table... Bluf! THAT Triggered exactly the same error described in that thread. I even tried the workaround (drag the table) but it didn't work. Suddenly I noticed that the schema was incorrect, I updated it, tried again, and Eureka! the problem was immediately away... Regards.

It can be very confusing, and dangerous, to replace the upstream base repositories with add-on repositories without considerable testing and thought. RPMforge, in particularly, is effectively moribund and is not getting updates.

I personally publish tools for building git 2.4, wrapped as an alternatively named "git24" package, at https://github.com/nkadel/git24-srpm/. Feel free to access and fork those if you want packages distinguished from the standard system packages, much as "samba" and "samba4" packages are differentiated.

select table1.price, table2.price as other_price .....

I'm not sure but in this case you can still go with a complete customized AlertDialog by having a seperate layout file set in the alert dialog and set the animation for your imageview using part of your above code that should also do it!

Here is a list of special characters that you can escape when creating a string literal for JSON:

\b  Backspace (ASCII code 08)
\f  Form feed (ASCII code 0C)
\n  New line
\r  Carriage return
\t  Tab
\v  Vertical tab
\'  Apostrophe or single quote
\"  Double quote
\\  Backslash character

Reference: String literals

Some of these are more optional than others. For instance, your string should be perfectly valid whether you escape the tab character or leave in a tab literal. You should certainly be handling the backslash and quote characters, though.

There is no static Equals method in the Array class, so what you are using is actually Object.Equals, which determines if the two object references point to the same object.

If you want to check if the arrays contains the same items in the same order, you can use the SequenceEquals extension method:

childe1.SequenceEqual(grandFatherNode)

Edit:

To use SequenceEquals with multidimensional arrays, you can use an extension to enumerate them. Here is an extension to enumerate a two dimensional array:

public static IEnumerable<T> Flatten<T>(this T[,] items) {
  for (int i = 0; i < items.GetLength(0); i++)
    for (int j = 0; j < items.GetLength(1); j++)
      yield return items[i, j];
}

Usage:

childe1.Flatten().SequenceEqual(grandFatherNode.Flatten())

If your array has more dimensions than two, you would need an extension that supports that number of dimensions. If the number of dimensions varies, you would need a bit more complex code to loop a variable number of dimensions.

You would of course first make sure that the number of dimensions and the size of the dimensions of the arrays match, before comparing the contents of the arrays.

Edit 2:

Turns out that you can use the OfType<T> method to flatten an array, as RobertS pointed out. Naturally that only works if all the items can actually be cast to the same type, but that is usually the case if you can compare them anyway. Example:

childe1.OfType<Person>().SequenceEqual(grandFatherNode.OfType<Person>())

For those who are looking to combine 2 color images into one, this is a slight mod on Andrey's answer which worked for me :

img1 = cv2.imread(imageFile1)
img2 = cv2.imread(imageFile2)

h1, w1 = img1.shape[:2]
h2, w2 = img2.shape[:2]

#create empty matrix
vis = np.zeros((max(h1, h2), w1+w2,3), np.uint8)

#combine 2 images
vis[:h1, :w1,:3] = img1
vis[:h2, w1:w1+w2,:3] = img2

Try this:

Select Project_Name, ReleaseDate, TaskName
From DB_Table
Where Project_Name like '{?Pm-?Proj_Name}'
  And ReleaseDate >= currentdate

currentdate should be a valid database function or field to work. If you are using MS SQL Server, use GETDATE() instead.

If all you want is to filter records in a subreport based on a parameter from the main report, it might be easier to simply add the table to the subreport, and then create a Project_Name link between the main report and subreport. You can then use the Select Expert to filter the ReleaseDate as well.

One way is to create a handler function. Define the handler early on, and put the handler below all the methods you need to call.

Then when you invoke the handler method to call your functions, they will always be available.

The handler could take an argument nameOfMethodToCall. Then uses a bunch of if statements to call the right method.

This would solve your issue.

def foo():
    print("foo")
    #take input
    nextAction=input('What would you like to do next?:')
    return nextAction

def bar():
    print("bar")
    nextAction=input('What would you like to do next?:')
    return nextAction

def handler(action):
    if(action=="foo"):
        nextAction = foo()
    elif(action=="bar"):
        nextAction = bar()
    else:
        print("You entered invalid input, defaulting to bar")
        nextAction = "bar"
    return nextAction

nextAction=input('What would you like to do next?:')

while 1:
    nextAction = handler(nextAction)

I had the same problem trying to make an interactive ssh session using ssh, a fork of Paramiko.

I dug around and found this article:

Updated link (last version before the link generated a 404): http://web.archive.org/web/20170912043432/http://jessenoller.com/2009/02/05/ssh-programming-with-paramiko-completely-different/

To continue your example you could do

ssh_stdin, ssh_stdout, ssh_stderr = ssh.exec_command("psql -U factory -d factory -f /tmp/data.sql")
ssh_stdin.write('password\n')
ssh_stdin.flush()
output = ssh_stdout.read()

The article goes more in depth, describing a fully interactive shell around exec_command. I found this a lot easier to use than the examples in the source.

All tables within the bootstrap stretch according to their container, which you can easily do by placing your table inside a .span* grid element of your choice. If you wish to remove this property you can create your own table class and simply add it to the table you want to expand with the content within:

.table-nonfluid {
   width: auto !important;
}

You can add this class inside your own stylesheet and simply add it to the container of your table like so:

<table class="table table-nonfluid"> ... </table>

This way your change won't affect the bootstrap stylesheet itself (you might want to have a fluid table somewhere else in your document).

This may be obvious, but you can inline the array like so:

package main

import (
    "fmt"
)

func main() {
    for _, element := range [3]string{"a", "b", "c"} {
        fmt.Print(element)
    }
}

outputs:

abc

I used following logic and it worked for me like marvel:

CONVERT(TIME, DATEADD(MINUTE, DATEDIFF(MINUTE, AP.Time_IN, AP.Time_OUT), 0)) 

If you have a xml like below

<e:Envelope
    xmlns:d = "http://www.w3.org/2001/XMLSchema"
    xmlns:e = "http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:wn0 = "http://systinet.com/xsd/SchemaTypes/"
    xmlns:i = "http://www.w3.org/2001/XMLSchema-instance">
    <e:Header>
        <Friends>
            <friend>
                <Name>Testabc</Name>
                <Age>12121</Age>
                <Phone>Testpqr</Phone>
            </friend>
        </Friends>
    </e:Header>
    <e:Body>
        <n0:ForAnsiHeaderOperResponse xmlns:n0 = "http://systinet.com/wsdl/com/magicsoftware/ibolt/localhost/ForAnsiHeader/ForAnsiHeaderImpl#ForAnsiHeaderOper?KExqYXZhL2xhbmcvU3RyaW5nOylMamF2YS9sYW5nL1N0cmluZzs=">
            <response i:type = "d:string">12--abc--pqr</response>
        </n0:ForAnsiHeaderOperResponse>
    </e:Body>
</e:Envelope>

and wanted to extract the below xml

<e:Header>
   <Friends>
      <friend>
         <Name>Testabc</Name>
         <Age>12121</Age>
         <Phone>Testpqr</Phone>
      </friend>
   </Friends>
</e:Header>

The below code helps to achieve the same

public static void main(String[] args) {

    File fXmlFile = new File("C://Users//abhijitb//Desktop//Test.xml");
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    Document document;
    Node result = null;
    try {
        document = dbf.newDocumentBuilder().parse(fXmlFile);
        XPath xPath = XPathFactory.newInstance().newXPath();
        String xpathStr = "//Envelope//Header";
        result = (Node) xPath.evaluate(xpathStr, document, XPathConstants.NODE);
        System.out.println(nodeToString(result));
    } catch (SAXException | IOException | ParserConfigurationException | XPathExpressionException
            | TransformerException e) {
        e.printStackTrace();
    }
}

private static String nodeToString(Node node) throws TransformerException {
    StringWriter buf = new StringWriter();
    Transformer xform = TransformerFactory.newInstance().newTransformer();
    xform.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
    xform.transform(new DOMSource(node), new StreamResult(buf));
    return (buf.toString());
}

Now if you want only the xml like below

<Friends>
   <friend>
      <Name>Testabc</Name>
      <Age>12121</Age>
      <Phone>Testpqr</Phone>
   </friend>
</Friends>

You need to change the

String xpathStr = "//Envelope//Header"; to String xpathStr = "//Envelope//Header/*";

Instead of having the error set to NULL, have it set to

NSError *error;
[fileManager removeItemAtPath:filePath error:&error];
if (error){
NSLog(@"%@", error);
}

this will tell you if it's actually deleting the file

Try:

<table border="1">
  <tr>
    <td>
      <table border="">
      ...
      </table>
    </td>
  </tr>
</table>

Readonly will allow the user to copy text from it. Disabled will not.

Pass the arguments to the run command from within gdb.

$ gdb ./a.out
(gdb) r < t
Starting program: /dir/a.out < t

You need to access the underlying buffer:

printf("%s\n", someString.c_str());

Or better use cout << someString << endl; (you need to #include <iostream> to use cout)

Additionally you might want to import the std namespace using using namespace std; or prefix both string and cout with std::.

It gives you the remainder of a division.

int c=11, d=5;
cout << (c/d) * d + c % d; // gives you the value of c

Here's a solution that is simple, short, easy to understand, and works perfectly for me. I needed to draw to the screen when another thread ends; but couldn't because the main thread has control of the screen. So:

(1) I created the global variable: boolean end1 = false; The thread sets it to true when ending. That is picked up in the mainthread by "postDelayed" loop, where it is responded to.

(2) My thread contains:

void myThread() {
    end1 = false;
    new CountDownTimer(((60000, 1000) { // milliseconds for onFinish, onTick
        public void onFinish()
        {
            // do stuff here once at end of time.
            end1 = true; // signal that the thread has ended.
        }
        public void onTick(long millisUntilFinished)
        {
          // do stuff here repeatedly.
        }
    }.start();

}

(3) Fortunately, "postDelayed" runs in the main thread, so that's where in check the other thread once each second. When the other thread ends, this can begin whatever we want to do next.

Handler h1 = new Handler();

private void checkThread() {
   h1.postDelayed(new Runnable() {
      public void run() {
         if (end1)
            // resond to the second thread ending here.
         else
            h1.postDelayed(this, 1000);
      }
   }, 1000);
}

(4) Finally, start the whole thing running somewhere in your code by calling:

void startThread()
{
   myThread();
   checkThread();
}

.removeAttr("style") to just get rid of the whole style tag...

.attr("style") to test the value and see if an inline style exists...

.attr("style",newValue) to set it to something else

The most likely possibility is that it was the most idiomatic choice. Not only is it easy to speak, but rather intuitive to understand. Some could argue, even more so than var.

But I reckon there's a little more history to this.

From Wikipedia:

Dana Scott's LCF language was a stage in the evolution of lambda calculus into modern functional languages. This language introduced the let expression, which has appeared in most functional languages since that time.

State-full imperative languages such as ALGOL and Pascal essentially implement a let expression, to implement restricted scope of functions, in block structures.

I would like to believe this was an inspiration too, for the let in Javascript.

A non-jQuery solution is much like a jQuery solution:

document.querySelector('#myinput').getAttribute('type') === 'checkbox'

You'd have to use WebSockets (or some similar protocol module e.g. as supported by the Flash plugin) because a normal browser application simply can't open a pure TCP socket.

The Socket.IO module available for node.js can help a lot, but note that it is not a pure WebSocket module in its own right.

It's actually a more generic communications module that can run on top of various other network protocols, including WebSockets, and Flash sockets.

Hence if you want to use Socket.IO on the server end you must also use their client code and objects. You can't easily make raw WebSocket connections to a socket.io server as you'd have to emulate their message protocol.

How to convert string to lowercase in Python?

Is there any way to convert an entire user inputted string from uppercase, or even part uppercase to lowercase?

E.g. Kilometers --> kilometers

The canonical Pythonic way of doing this is

>>> 'Kilometers'.lower()
'kilometers'

However, if the purpose is to do case insensitive matching, you should use case-folding:

>>> 'Kilometers'.casefold()
'kilometers'

Here's why:

>>> "Maße".casefold()
'masse'
>>> "Maße".lower()
'maße'
>>> "MASSE" == "Maße"
False
>>> "MASSE".lower() == "Maße".lower()
False
>>> "MASSE".casefold() == "Maße".casefold()
True

This is a str method in Python 3, but in Python 2, you'll want to look at the PyICU or py2casefold - several answers address this here.

Unicode Python 3

Python 3 handles plain string literals as unicode:

>>> string = '????????'
>>> string
'????????'
>>> string.lower()
'????????'

Python 2, plain string literals are bytes

In Python 2, the below, pasted into a shell, encodes the literal as a string of bytes, using utf-8.

And lower doesn't map any changes that bytes would be aware of, so we get the same string.

>>> string = '????????'
>>> string
'\xd0\x9a\xd0\xb8\xd0\xbb\xd0\xbe\xd0\xbc\xd0\xb5\xd1\x82\xd1\x80'
>>> string.lower()
'\xd0\x9a\xd0\xb8\xd0\xbb\xd0\xbe\xd0\xbc\xd0\xb5\xd1\x82\xd1\x80'
>>> print string.lower()
????????

In scripts, Python will object to non-ascii (as of Python 2.5, and warning in Python 2.4) bytes being in a string with no encoding given, since the intended coding would be ambiguous. For more on that, see the Unicode how-to in the docs and PEP 263

Use Unicode literals, not str literals

So we need a unicode string to handle this conversion, accomplished easily with a unicode string literal, which disambiguates with a u prefix (and note the u prefix also works in Python 3):

>>> unicode_literal = u'????????'
>>> print(unicode_literal.lower())
????????

Note that the bytes are completely different from the str bytes - the escape character is '\u' followed by the 2-byte width, or 16 bit representation of these unicode letters:

>>> unicode_literal
u'\u041a\u0438\u043b\u043e\u043c\u0435\u0442\u0440'
>>> unicode_literal.lower()
u'\u043a\u0438\u043b\u043e\u043c\u0435\u0442\u0440'

Now if we only have it in the form of a str, we need to convert it to unicode. Python's Unicode type is a universal encoding format that has many advantages relative to most other encodings. We can either use the unicode constructor or str.decode method with the codec to convert the str to unicode:

>>> unicode_from_string = unicode(string, 'utf-8') # "encoding" unicode from string
>>> print(unicode_from_string.lower())
????????
>>> string_to_unicode = string.decode('utf-8') 
>>> print(string_to_unicode.lower())
????????
>>> unicode_from_string == string_to_unicode == unicode_literal
True

Both methods convert to the unicode type - and same as the unicode_literal.

Best Practice, use Unicode

It is recommended that you always work with text in Unicode.

Software should only work with Unicode strings internally, converting to a particular encoding on output.

Can encode back when necessary

However, to get the lowercase back in type str, encode the python string to utf-8 again:

>>> print string
????????
>>> string
'\xd0\x9a\xd0\xb8\xd0\xbb\xd0\xbe\xd0\xbc\xd0\xb5\xd1\x82\xd1\x80'
>>> string.decode('utf-8')
u'\u041a\u0438\u043b\u043e\u043c\u0435\u0442\u0440'
>>> string.decode('utf-8').lower()
u'\u043a\u0438\u043b\u043e\u043c\u0435\u0442\u0440'
>>> string.decode('utf-8').lower().encode('utf-8')
'\xd0\xba\xd0\xb8\xd0\xbb\xd0\xbe\xd0\xbc\xd0\xb5\xd1\x82\xd1\x80'
>>> print string.decode('utf-8').lower().encode('utf-8')
????????

So in Python 2, Unicode can encode into Python strings, and Python strings can decode into the Unicode type.

You can download ip-tables from MaxMind:

http://www.maxmind.com/app/geolite

Import the CSV to your database (make sure to create an index for ip_long_from + ip_long_to). Then you can simply do:

$iplong = ip2long($_SERVER['REMOTE_ADDR']);

// should use mysqli with prepared statements etc, but just an example
mysql_query("
    SELECT country
    FROM ip_table
    WHERE $iplong BETWEEN ip_long_from AND ip_long_to
    LIMIT 1
");

Additional to previous answers, if you are having problems with getting the right path(like AndroZip) you can use this:

  public String getPath(Uri uri ,ContentResolver contentResolver) {
        String[] projection = {  MediaStore.MediaColumns.DATA};
        Cursor cursor;
        try{
            cursor = contentResolver.query(uri, projection, null, null, null);
        } catch (SecurityException e){
            String path = uri.getPath();
            String result = tryToGetStoragePath(path);
            return  result;
        }
        if(cursor != null) {
            //HERE YOU WILL GET A NULLPOINTER IF CURSOR IS NULL
            //THIS CAN BE, IF YOU USED OI FILE MANAGER FOR PICKING THE MEDIA
            cursor.moveToFirst();
            int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA);
            String filePath = cursor.getString(columnIndex);
            cursor.close();
            return filePath;
        }
        else
            return uri.getPath();               // FOR OI/ASTRO/Dropbox etc
    }

    private String tryToGetStoragePath(String path) {
        int actualPathStart = path.indexOf("//storage");
        String result = path;

        if(actualPathStart!= -1 && actualPathStart< path.length())
            result = path.substring(actualPathStart+1 , path.length());

        return result;
    }

Adding everything together, it is a good idea to trim for extra white space at beginning of string. Otherwise, .substring(0,1).toUpperCase will try to capitalize a white space.

    public String capitalizeFirstLetter(String original) {
        if (original == null || original.length() == 0) {
            return original;
        }
        return original.trim().substring(0, 1).toUpperCase() + original.substring(1);
    }

Hopefully, it will work for you.

df_1.merge(df_2)

• on parameter has different meaning in both cases

pip won't handle system level dependencies. You'll have to apt-get install libfreetype6-dev before continuing. (It even says so right in your output. Try skimming over it for such errors next time, usually build outputs are very detailed)

First of all I got this in VS2017 with an old project I needed to make a tiny change to and upraded all the projects to framework 4.7.

Several others have mentioned selecting Any CPU can fix this issue.

There's a couple places you need to do it, and it might not just be as simple as selecting from the dropdown. This fixed it for me:

1) You need to do it both here:

2) And also in Configuration Manager (right click on solution)

But what if it isn't there???

Then click New and choose these settings: (thanks @RckLN)

If you don't want to map ports from your host to the container you can access directly to the docker range ip for the container. This range is by default only accessed from your host. You can check your container network data doing:

docker inspect <containerNameOrId>

Probably is better to filter:

docker inspect <containerNameOrId> | grep '"IPAddress"' | head -n 1

Usually, the default docker ip range is 172.17.0.0/16. Your host should be 172.17.0.1 and your first container should be 172.17.0.2 if everything is normal and you didn't specify any special network options.

EDIT Another more elegant way using docker features instead of "bash tricking":

docker inspect -f "{{ .NetworkSettings.IPAddress }}" <containerNameOrId>

As everyone said, this represents the current object / current instance. I understand it this way, if its just "this" - it returns class object, in below ex: Dog if it has this.something, something is a method in that class or a variable

class Dog {
private String breed;
private String name;

Dog(String breed, String name) {
    this.breed = breed;
    this.name = name;
}

public Dog getDog() {
    // return Dog type
    return this;
}

}

1. Where does user.id go after passport.serializeUser has been called?

The user id (you provide as the second argument of the done function) is saved in the session and is later used to retrieve the whole object via the deserializeUser function.

serializeUser determines which data of the user object should be stored in the session. The result of the serializeUser method is attached to the session as req.session.passport.user = {}. Here for instance, it would be (as we provide the user id as the key) req.session.passport.user = {id: 'xyz'}

2. We are calling passport.deserializeUser right after it where does it fit in the workflow?

The first argument of deserializeUser corresponds to the key of the user object that was given to the done function (see 1.). So your whole object is retrieved with help of that key. That key here is the user id (key can be any key of the user object i.e. name,email etc). In deserializeUser that key is matched with the in memory array / database or any data resource.

The fetched object is attached to the request object as req.user

Visual Flow

passport.serializeUser(function(user, done) {
    done(null, user.id);
});              ¦
                 ¦ 
                 ¦
                 +--------------------? saved to session
                                   ¦    req.session.passport.user = {id: '..'}
                                   ¦
                                   ?           
passport.deserializeUser(function(id, done) {
                   +---------------+
                   ¦
                   ? 
    User.findById(id, function(err, user) {
        done(err, user);
    });            +--------------? user object attaches to the request as req.user   
});

I know this is an old thread, but I wanted to share a solution I ended up having to use since the accepted post still has an issue.

The Issue:

As pointed out by Alexandre Severino, if param (in the function below) changes shortly after the function call, you might get some unexpected behavior in MethodWithParameter.

Task.Run(() => MethodWithParameter(param)); 

My Solution:

To account for this, I ended up writing something more like the following line of code:

(new Func<T, Task>(async (p) => await Task.Run(() => MethodWithParam(p)))).Invoke(param);

This allowed me to safely use the parameter asynchronously despite the fact that the parameter changed very quickly after starting the task (which caused issues with the posted solution).

Using this approach, param (value type) gets its value passed in, so even if the async method runs after param changes, p will have whatever value param had when this line of code ran.

With Tomcat 7, you can add the StuckThreadDetectionValve which will enable you to identify threads that are "stuck". You can set-up the valve in the Context element of the applications where you want to do detecting:

<Context ...>
  ...
  <Valve 
    className="org.apache.catalina.valves.StuckThreadDetectionValve"
    threshold="60" />
  ...
</Context>

This would write a WARN entry into the tomcat log for any thread that takes longer than 60 seconds, which would enable you to identify the applications and ban them because they are faulty.

Based on the source code you may be able to write your own valve that attempts to stop the thread, however this would have knock on effects on the thread pool and there is no reliable way of stopping a thread in Java without the cooperation of that thread...

I made a Method to do this

    string test = "Paul";
    test = ReplaceAtIndex(0, 'M', test);

    (...)

    static string ReplaceAtIndex(int i, char value, string word)
    {
        char[] letters = word.ToCharArray();
        letters[i] = value;
        return string.Join("", letters);
    }

I had the same issue. The branch I was working on wasn't being tracked. The fix was:

git push orgin

This fixed it temporarily. To make the changes pertinently I:

git config push.default tracking

Matter of style, but as Matt said, definitely consider marking constructors with default arguments which would allow implicit conversion as 'explicit' to avoid unintended automatic conversion. It's not a requirement (and may not be preferable if you're making a wrapper class which you want to implicitly convert to), but it can prevent errors.

I personally like defaults when appropriate, because I dislike repeated code. YMMV.

using ssh from java should not be as hard as jsch makes it. you might be better off with sshj.

If someone wants to add a legend and/or colors to some vertical lines, then use this:

import matplotlib.pyplot as plt

# x coordinates for the lines
xcoords = [0.1, 0.3, 0.5]
# colors for the lines
colors = ['r','k','b']

for xc,c in zip(xcoords,colors):
    plt.axvline(x=xc, label='line at x = {}'.format(xc), c=c)

plt.legend()
plt.show()

Results:

I was interested in this question, so I did a test just now. Using .NET Framework 4.5.2 on an Intel(R) Core(TM) i3-2328M CPU @ 2.20GHz, 2200 Mhz, 2 Core(s) with 8GB ram running Microsoft Windows 7 Ultimate.

It looks like LINQ might be faster than for each loop. Here are the results I got:

Exists = True
Time   = 174
Exists = True
Time   = 149

It would be interesting if some of you could copy & paste this code in a console app and test as well. Before testing with an object (Employee) I tried the same test with integers. LINQ was faster there as well.

As stated by pnt you can have multiple versions of both 32bit and 64bit Java installed at the same time on the same machine.

Taking it further from there: Here's how it might be possible to set any runtime parameters for each of those installations:

You can run javacpl.exe or javacpl.cpl of the respective Java-version itself (bin-folder). The specific control panel opens fine. Adding parameters there is possible.

Interesting, this is probably a "feature request" (ie bug) for jQuery. The jQuery click event only triggers the click action (called onClick event on the DOM) on the element if you bind a jQuery event to the element. You should go to jQuery mailing lists ( http://forum.jquery.com/ ) and report this. This might be the wanted behavior, but I don't think so.

EDIT:

I did some testing and what you said is wrong, even if you bind a function to an 'a' tag it still doesn't take you to the website specified by the href attribute. Try the following code:

<html>
<head>

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>
 <script>
  $(document).ready(function() {
   /* Try to dis-comment this:
   $('#a').click(function () {
    alert('jQuery.click()');
    return true;
   });
   */
  });
  function button_onClick() {
   $('#a').click();
  }
  function a_onClick() {
   alert('a_onClick');
  }
 </script>

</head>
<body>
 <input type="button" onclick="button_onClick()">
 <br>
 <a id='a' href='http://www.google.com' onClick="a_onClick()"> aaa </a>

</body>
</html> 

It never goes to google.com unless you directly click on the link (with or without the commented code). Also notice that even if you bind the click event to the link it still doesn't go purple once you click the button. It only goes purple if you click the link directly.

I did some research and it seems that the .click is not suppose to work with 'a' tags because the browser does not suport "fake clicking" with javascript. I mean, you can't "click" an element with javascript. With 'a' tags you can trigger its onClick event but the link won't change colors (to the visited link color, the default is purple in most browsers). So it wouldn't make sense to make the $().click event work with 'a' tags since the act of going to the href attribute is not a part of the onClick event, but hardcoded in the browser.

This can happen when your plot panel in RStudio is too small for the margins of the plot you are trying to create. Try making expanding it and then run your code again.

RStudio UI causes an error when the plot panel is too small to display the chart:

Simply expanding the plot panel fixes the bug and displays the chart:

It is because Bootstrap's DEFAULT CSS for <hr /> is ::

hr {
    margin-top: 20px;
    margin-bottom: 20px;
    border: 0;
    border-top: 1px solid #eeeeee;
}

it creates 40px gap between those two lines

so if you want to change any particular <hr /> margin style in your page you may try something like this ::

<hr style="margin-bottom:5px !important; margin-top:5px !important; " />

if you want to change appearance/other styles of any particular <hr /> in your page like color and border type or thickness the you may try something like :

<hr style="border-top: 1px dotted #000000 !important; " />

for all <hr /> in your page

<style>
   hr {
       border-top: 1px dotted #000000 !important;
       margin-bottom:5px !important; 
       margin-top:5px !important;
   }
</style>

$(".edgetoedge>li").removeClass("highlight");

In combination with all the answers above, I wanted the ImageView to be pressed and changed state but if the user moved then "cancel" and not perform an onClickListener.

I ended up making a Point object within the class and setting its coordinates according to when the user pushed down on the ImageView. On the MotionEvent.ACTION_UP I recording a new point and compared the points.

I can only explain it so well, but here is what I did.

// set the ontouch listener
weatherView.setOnTouchListener(new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        // Determine what action with a switch statement
        switch (event.getAction()) {

        // User presses down on the ImageView, record the original point
        // and set the color filter
        case MotionEvent.ACTION_DOWN: {
            ImageView view = (ImageView) v;

            // overlay is black with transparency of 0x77 (119)
            view.getDrawable().setColorFilter(0x77000000,
                    PorterDuff.Mode.SRC_ATOP);
            view.invalidate();

            p = new Point((int) event.getX(), (int) event.getY());
            break;
        }

        // Once the user releases, record new point then compare the
        // difference, if within a certain range perform onCLick
        // and or otherwise clear the color filter
        case MotionEvent.ACTION_UP: {
            ImageView view = (ImageView) v;
            Point f = new Point((int) event.getX(), (int) event.getY());
            if ((Math.abs(f.x - p.x) < 15)
                    && ((Math.abs(f.x - p.x) < 15))) {
                view.performClick();
            }
            // clear the overlay
            view.getDrawable().clearColorFilter();
            view.invalidate();
            break;
        }
        }
        return true;
    }
});

I have an onClickListener set on the imageView, but this can be an method.

For the most common purpose, you should use bindValue.

bindParam has two tricky or unexpected behaviors:

• bindParam(':foo', 4, PDO::PARAM_INT) does not work, as it requires passing a variable (as reference).
• bindParam(':foo', $value, PDO::PARAM_INT) will change $value to string after running execute(). This, of course, can lead to subtle bugs that might be difficult to catch.

I hope this helps someone! :)

Query params are used like this:

use Illuminate\Http\Request;

class MyController extends BaseController{

    public function index(Request $request){
         $param = $request->query('param');
    }

Just check the bootstrap. CSS and search for the class panel-heading and copy the default code.

Copy the default CSS to your personal CSS but vive it a diference classname like my-panel-header for example.

Edit the css Code from the new clones class created.

Any of the below three options works for you:

echo[

echo(

echo. 

For example:

@echo off
echo There will be a blank line below
echo[
echo Above line is blank
echo( 
echo The above line is also blank.
echo. 
echo The above line is also blank.

You can tell ESLint to ignore specific files and directories by creating an .eslintignore file in your project’s root directory:

.eslintignore

build/*.js
config/*.js
bower_components/foo/*.js

The ignore patterns behave according to the .gitignore specification. (Don't forget to restart your editor.)

How about i-net Clear Reports (used to be i-net Crystal-Clear).

Though not free, you should also consider this low-cost, non-free, non-open-source reporting solution that can fully compete with Crystal Reports - and is Java-based.

I think it's even more cost efficient than "free ones". A small company may have to think closely about free things, but will then have to invest into manpower to find out how everything works and so on. Large companies will for sure subscribe to premium support services that cost a lot. See this article for reference

i-net Clear Reports has a very low price tag with great support for free and even better premium support via yearly subscriptions.

Disclosure: Yeah, I work for the company who built this, so I'm biased. But I honestly believe in what I just wrote.

I was facing the same issue with jenkins ssh slave 'jenkinsci/ssh-slave'. However, my case was a bit complicated because it was necessary to pass an argument which contained spaces. I've managed to do it like below (entrypoint in dockerfile is in exec form):

command: ["some argument with space which should be treated as one"]

You can also do this to set a header for all future gets for the Session object, where x-test will be in all s.get() calls:

s = requests.Session()
s.auth = ('user', 'pass')
s.headers.update({'x-test': 'true'})

# both 'x-test' and 'x-test2' are sent
s.get('http://httpbin.org/headers', headers={'x-test2': 'true'})

from: http://docs.python-requests.org/en/latest/user/advanced/#session-objects

consider using

df['column name'].astype('Int64')

nan will be changed to NaN

We can use following code

textBox1.DataBindings.Add("Text", model, "Name", false, DataSourceUpdateMode.OnPropertyChanged);

Where

• "Text" – the property of textbox
• model – the model object enter code here
• "Name" – the value of model which to bind the textbox.

From the Java Documentation:

[...] More surprisingly, class Class has been generified. Class literals now function as type tokens, providing both run-time and compile-time type information. This enables a style of static factories exemplified by the getAnnotation method in the new AnnotatedElement interface:

<T extends Annotation> T getAnnotation(Class<T> annotationType); 

This is a generic method. It infers the value of its type parameter T from its argument, and returns an appropriate instance of T, as illustrated by the following snippet:

Author a = Othello.class.getAnnotation(Author.class);

Prior to generics, you would have had to cast the result to Author. Also you would have had no way to make the compiler check that the actual parameter represented a subclass of Annotation. [...]

Well, I never had to use this kind of stuff. Anyone?

This function normalizes down all whitespace, including line breaks, to single spaces. Not exactly what the original question asked for, but likely to do exactly what is needed in many cases:

import org.apache.commons.lang3.StringUtils;

final String cleansedString = StringUtils.normalizeSpace(rawString);

I know it's old question but it still in first 10 links in google.

It is not very efficient to save rows one-by-one because it cause database call in the loop and you better avoid that, especially when you need to insert huge portions of data.

It's better (and significantly faster) to use batch insert.

INSERT INTO `mouldings` (suppliers_code, name, cost)
VALUES
    ('s1', 'supplier1', 1.111), 
    ('s2', 'supplier2', '2.222')

You can build such a query manually and than do Model.connection.execute(RAW SQL STRING) (not recomended) or use gem activerecord-import (it was first released on 11 Aug 2010) in this case just put data in array rows and call Model.import rows

refer to gem docs for details

Python dicts are not sorted, by definition. You cannot sort one, nor control the order of its elements by how you insert them. You might want to look at collections.OrderDict, which even comes with a little tutorial for almost exactly what you're trying to do: http://docs.python.org/2/library/collections.html#ordereddict-examples-and-recipes

Another way is to use a lambda expression. Depending on interpreter version and whether you wish to create a sorted dictionary or sorted key-value tuples (as the OP does), this may even be faster than the accepted answer.

d = {'aa': 3, 'bb': 4, 'cc': 2, 'dd': 1}
s = sorted(d.items(), key=lambda x: x[1], reverse=True)

for k, v in s:
    print(k, v)

I can't add a comment above as I do not have enough reputation, but the above answer was nearly perfect for me, except I had to add

type: "POST"

to the .ajax call. I was scratching my head for a few minutes trying to figure out what I had done wrong, that's all it needed and works a treat. So this is the whole snippet:

Full credit to the answer above me, this is just a small tweak to that. This is just in case anyone else gets stuck and can't see the obvious.

  $.ajax({
    url: 'Your url here',
    data: formData,
    type: "POST", //ADDED THIS LINE
    // THIS MUST BE DONE FOR FILE UPLOADING
    contentType: false,
    processData: false,
    // ... Other options like success and etc
})

We can use params, new feature of the UI-Router:

API Reference / ui.router.state / $stateProvider

params A map which optionally configures parameters declared in the url, or defines additional non-url parameters. For each parameter being configured, add a configuration object keyed to the name of the parameter.

See the part: "...or defines additional non-url parameters..."

So the state def would be:

$stateProvider
  .state('home', {
    url: "/home",
    templateUrl: 'tpl.html',
    params: { hiddenOne: null, }
  })

Few examples form the doc mentioned above:

// define a parameter's default value
params: {
  param1: { value: "defaultValue" }
}
// shorthand default values
params: {
  param1: "defaultValue",
  param2: "param2Default"
}

// param will be array []
params: {
  param1: { array: true }
}

// handling the default value in url:
params: {
  param1: {
    value: "defaultId",
    squash: true
} }
// squash "defaultValue" to "~"
params: {
  param1: {
    value: "defaultValue",
    squash: "~"
  } }

EXTEND - working example: http://plnkr.co/edit/inFhDmP42AQyeUBmyIVl?p=info

Here is an example of a state definition:

 $stateProvider
  .state('home', {
      url: "/home",
      params : { veryLongParamHome: null, },
      ...
  })
  .state('parent', {
      url: "/parent",
      params : { veryLongParamParent: null, },
      ...
  })
  .state('parent.child', { 
      url: "/child",
      params : { veryLongParamChild: null, },
      ...
  })

This could be a call using ui-sref:

<a ui-sref="home({veryLongParamHome:'Home--f8d218ae-d998-4aa4-94ee-f27144a21238'
  })">home</a>

<a ui-sref="parent({ 
    veryLongParamParent:'Parent--2852f22c-dc85-41af-9064-d365bc4fc822'
  })">parent</a>

<a ui-sref="parent.child({
    veryLongParamParent:'Parent--0b2a585f-fcef-4462-b656-544e4575fca5',  
    veryLongParamChild:'Child--f8d218ae-d998-4aa4-94ee-f27144a61238'
  })">parent.child</a>

Spent a great deal of time troubleshooting this issue myself.

Using PHP, and Nothing on this page worked for me. I eventually realized in my code that the 'secure' parameter to PHP's session_set_cookie_params() was always being set to TRUE.

Since I wasn't visiting localhost with https my browser would never accept the cookie. So, I modified that portion of my code to conditionally set the 'secure' param based on $_SERVER['HTTP_HOST'] being 'localhost' or not. Working well now.

I hope this helps someone.

public async Task<bool> Update(MyObject item)
{
    Context.Entry(await Context.MyDbSet.FirstOrDefaultAsync(x => x.Id == item.Id)).CurrentValues.SetValues(item);
    return (await Context.SaveChangesAsync()) > 0;
}

You should have a /etc/php2/conf.d directory (At least on Ubuntu I do) containing a bunch of .ini files which all get loaded when php runs. These files can contain duplicate settings that conflict with settings in php.ini. In my PHP installation I notice a file conf.d/20-intl.ini with an extension=intl.so setting. I bet that's your conflict.

You also can use ng-attr-src="{{variable}}" instead of src="{{variable}}" and the attribute will only be generated once the compiler compiled the templates. This is mentioned here in the documentation: https://docs.angularjs.org/guide/directive#-ngattr-attribute-bindings

class Class1(object):
    pass

class Class2(Class1):
    pass

Class2 is a sub-class of Class1

Help yourself:

public void clearAdapter() {
    arrayNull.clear();
    notifyDataSetChanged();
}

The best way to do this is probably to use a third party library.

There's an implementation of what you're looking for in jQuery UI jQuery UI and in dojo dojo. jQuery is more popular, but dojo allows you to declaratively define widgets in HTML, which sounds more like what you're looking for.

Which one you use will depend on your style, but both are developed for cross browser work, and both will be updated more often than copy and paste code.

My text marquee for more text, and position absolute enabled

http://jsfiddle.net/zrW5q/2075/

(function($) {
$.fn.textWidth = function() {
var calc = document.createElement('span');
$(calc).text($(this).text());
$(calc).css({
  position: 'absolute',
  visibility: 'hidden',
  height: 'auto',
  width: 'auto',
  'white-space': 'nowrap'
});
$('body').append(calc);
var width = $(calc).width();
$(calc).remove();
return width;
};

$.fn.marquee = function(args) {
var that = $(this);
var textWidth = that.textWidth(),
    offset = that.width(),
    width = offset,
    css = {
        'text-indent': that.css('text-indent'),
        'overflow': that.css('overflow'),
        'white-space': that.css('white-space')
    },
    marqueeCss = {
        'text-indent': width,
        'overflow': 'hidden',
        'white-space': 'nowrap'
    },
    args = $.extend(true, {
        count: -1,
        speed: 1e1,
        leftToRight: false
    }, args),
    i = 0,
    stop = textWidth * -1,
    dfd = $.Deferred();

function go() {
    if (that.css('overflow') != "hidden") {
        that.css('text-indent', width + 'px');
        return false;
    }
    if (!that.length) return dfd.reject();

    if (width <= stop) {
        i++;
        if (i == args.count) {
            that.css(css);
            return dfd.resolve();
        }
        if (args.leftToRight) {
            width = textWidth * -1;
        } else {
            width = offset;
        }
    }
    that.css('text-indent', width + 'px');
    if (args.leftToRight) {
        width++;
    } else {
        width--;
    }
    setTimeout(go, args.speed);
};

if (args.leftToRight) {
    width = textWidth * -1;
    width++;
    stop = offset;
} else {
    width--;
}
that.css(marqueeCss);
go();
return dfd.promise();
};
// $('h1').marquee();
$("h1").marquee();
$("h1").mouseover(function () {     
    $(this).removeAttr("style");
}).mouseout(function () {
    $(this).marquee();

})(jQuery);

Use the -o option.

git commit -o path/to/myfile -m "the message"

-o, --only commit only specified files

For data up to 8000 characters use:

CONVERT(VARCHAR(32), HashBytes('MD5', '[email protected]'), 2)

Demo

For binary data (without the limit of 8000 bytes) use:

CONVERT(VARCHAR(32), master.sys.fn_repl_hash_binary(@binary_data), 2)

Demo

See answer from Gary Makin. And you need change the format or data. Because the data that you have do not fit under the chosen format. For example this code works correct:

let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy"
let dateObj = dateFormatter.dateFromString("10 10 2001")
print("Dateobj: \(dateObj)")

A quicker faster version would use mt_rand:

$min=1;
$max=20;
echo mt_rand($min,$max);

Source: http://www.php.net/manual/en/function.mt-rand.php.

NOTE: Your server needs to have the Math PHP module enabled for this to work. If it doesn't, bug your host to enable it, or you have to use the normal (and slower) rand().

You can pass as many arguments as you want, separating them by commas:

{{ path('_files_manage', {project: project.id, user: user.id}) }}

In my case I don't have issues with ~/.composer.
So being inside Laravel app root folder, I did sudo chown -R $USER composer.lock and it was helpful.

brew install ffmpeg will install what you need and all the dependencies if you are on a Mac.

=== and !== are strict comparison operators:

JavaScript has both strict and type-converting equality comparison. For strict equality the objects being compared must have the same type and:

• Two strings are strictly equal when they have the same sequence of characters, same length, and same characters in corresponding positions.
• Two numbers are strictly equal when they are numerically equal (have the same number value). NaN is not equal to anything, including NaN. Positive and negative zeros are equal to one another.
• Two Boolean operands are strictly equal if both are true or both are false.
• Two objects are strictly equal if they refer to the same Object.
• Null and Undefined types are == (but not ===). [I.e. (Null==Undefined) is true but (Null===Undefined) is false]

                   "VALUES (@FN, @LN, @UN, @Pass, @Age, @Gender, @Contact) ";

    // instance connection and command
    using(SqlConnection cn = new SqlConnection(connectionString))
    using(SqlCommand cmd = new SqlCommand(query, cn))
