I was running into this issue and it turned out that I needed to do this:

docker run ${image_name} bash -c "${command}"

Hope that helps someone who finds this error.

downloaded pgadmin 4 v2.0 and install it no problem atm on force installation. try it. that was solution for me.

I'm getting OpenJDK 8 from the official Debian repositories, rather than some random PPA or non-free Oracle binary. Here's how I did it:

sudo apt-get install debian-keyring debian-archive-keyring

Make /etc/apt/sources.list.d/debian-jessie-backports.list:

deb http://httpredir.debian.org/debian/ jessie-backports main

Make /etc/apt/preferences.d/debian-jessie-backports:

Package: *
Pin: release o=Debian,a=jessie-backports
Pin-Priority: -200

Then finally do the install:

sudo apt-get update
sudo apt-get -t jessie-backports install openjdk-8-jdk

Just for providing a more general (not mysql specific) answer...

1. In short

Synchronize with service image registry (https://docs.docker.com/compose/compose-file/#image):

docker-compose pull 

Recreate container if docker-compose file or image have changed:

docker-compose up -d

2. Background

Container image management is one of the reason for using docker-compose (see https://docs.docker.com/compose/reference/up/)

If there are existing containers for a service, and the service’s configuration or image was changed after the container’s creation, docker-compose up picks up the changes by stopping and recreating the containers (preserving mounted volumes). To prevent Compose from picking up changes, use the --no-recreate flag.

Data management aspect being also covered by docker-compose through mounted external "volumes" (See https://docs.docker.com/compose/compose-file/#volumes) or data container.

This leaves potential backward compatibility and data migration issues untouched, but these are "applicative" issues, not Docker specific, which have to be checked against release notes and tests...

To attempt command line arguments directly is not possible.

One alternative might be environment variables (https://superuser.com/questions/728951/systemd-giving-my-service-multiple-arguments).

This is where I found the answer: http://www.freedesktop.org/software/systemd/man/systemctl.html

so sudo systemctl restart myprog -v -- systemctl will think you're trying to set one of its flags, not myprog's flag.

sudo systemctl restart myprog someotheroption -- systemctl will restart myprog and the someotheroption service, if it exists.

Just install the latest version from nondefault repository:

$ sudo add-apt-repository ppa:ubuntu-toolchain-r/test
$ sudo apt-get update
$ sudo apt-get install libstdc++6-4.7-dev

Most of the time we go for OrderedDict when we required a custom order not a generic one like ASC etc.

Here is the proposed solution:

import collections
ship = {"NAME": "Albatross",
         "HP":50,
         "BLASTERS":13,
         "THRUSTERS":18,
         "PRICE":250}

ship = collections.OrderedDict(ship)

print ship


new_dict = collections.OrderedDict()
new_dict["NAME"]=ship["NAME"]
new_dict["HP"]=ship["HP"]
new_dict["BLASTERS"]=ship["BLASTERS"]
new_dict["THRUSTERS"]=ship["THRUSTERS"]
new_dict["PRICE"]=ship["PRICE"]


print new_dict

This will be output:

OrderedDict([('PRICE', 250), ('HP', 50), ('NAME', 'Albatross'), ('BLASTERS', 13), ('THRUSTERS', 18)])
OrderedDict([('NAME', 'Albatross'), ('HP', 50), ('BLASTERS', 13), ('THRUSTERS', 18), ('PRICE', 250)])

Note: The new sorted dictionaries maintain their sort order when entries are deleted. But when new keys are added, the keys are appended to the end and the sort is not maintained.(official doc)

Did you try passwd -d root? Most likely, this will do what you want.

You can also manually edit /etc/shadow: (Create a backup copy. Be sure that you can log even if you mess up, for example from a rescue system.) Search for "root". Typically, the root entry looks similar to

root:$X$SK5xfLB1ZW:0:0...

There, delete the second field (everything between the first and second colon):

root::0:0...

Some systems will make you put an asterisk (*) in the password field instead of blank, where a blank field would allow no password (CentOS 8 for example)

root:*:0:0...

Save the file, and try logging in as root. It should skip the password prompt. (Like passwd -d, this is a "no password" solution. If you are really looking for a "blank password", that is "ask for a password, but accept if the user just presses Enter", look at the manpage of mkpasswd, and use mkpasswd to create the second field for the /etc/shadow.)

Here are two other software packages which can be used for DNS caching on Linux:

• dnsmasq
• bind

After configuring the software for DNS forwarding and caching, you then set the system's DNS resolver to 127.0.0.1 in /etc/resolv.conf.

If your system is using NetworkManager you can either try using the dns=dnsmasq option in /etc/NetworkManager/NetworkManager.conf or you can change your connection settings to Automatic (Address Only) and then use a script in the /etc/NetworkManager/dispatcher.d directory to get the DHCP nameserver, set it as the DNS forwarding server in your DNS cache software and then trigger a configuration reload.

If you do not want variables to be replaced, you need to surround EOL with single quotes.

cat >/tmp/myconfig.conf <<'EOL'
line 1, ${kernel}
line 2, 
line 3, ${distro}
line 4 line
... 
EOL

Previous example:

$ cat /tmp/myconfig.conf 
line 1, ${kernel}
line 2, 
line 3, ${distro}
line 4 line
... 

This took a while to get right. I had this issue when cross-compiling in Ubuntu for an ARM target. I solved it with:

PATH=$PATH:/ccpath/bin CC=ccname-gcc AR=ccname-ar LD=ccname-ld CPPFLAGS="-nostdinc -I/ccrootfs/usr/include ..." LDFLAGS=-L/ccrootfs/usr/lib ./autogen.sh --build=`config.guess` --host=armv5tejl-unknown-linux-gnueabihf

Notice CFLAGS is not used with autogen.sh/configure, using it gave me the error: "configure: error: C compiler cannot create executables". In the build environment I was using an autogen.sh script was provided, if you don't have an autogen.sh script substitute ./autogen.sh with ./configure in the command above. I ran config.guess on the target system to get the --host parameter.

After successfully running autogen.sh/configure, compile with:

PATH=$PATH:/ccpath/bin CC=ccname-gcc AR=ccname-ar LD=ccname-ld CPPFLAGS="-nostdinc -I/ccrootfs/usr/include ..." LDFLAGS=-L/ccrootfs/usr/lib CFLAGS="-march=... -mcpu=... etc." make

The CFLAGS I chose to use were: "-march=armv5te -fno-tree-vectorize -mthumb-interwork -mcpu=arm926ej-s". It will take a while to get all of the include directories set up correctly: you might want some includes pointing to your cross-compiler and some pointing to your root file system includes, and there will likely be some conflicts.

I'm sure this is not the perfect answer. And I am still seeing some include directories pointing to / and not /ccrootfs in the Makefiles. Would love to know how to correct this. Hope this helps someone.

Another approach (more words, less code) that may help:

The locations of local maxima and minima are also the locations of the zero crossings of the first derivative. It is generally much easier to find zero crossings than it is to directly find local maxima and minima.

Unfortunately, the first derivative tends to "amplify" noise, so when significant noise is present in the original data, the first derivative is best used only after the original data has had some degree of smoothing applied.

Since smoothing is, in the simplest sense, a low pass filter, the smoothing is often best (well, most easily) done by using a convolution kernel, and "shaping" that kernel can provide a surprising amount of feature-preserving/enhancing capability. The process of finding an optimal kernel can be automated using a variety of means, but the best may be simple brute force (plenty fast for finding small kernels). A good kernel will (as intended) massively distort the original data, but it will NOT affect the location of the peaks/valleys of interest.

Fortunately, quite often a suitable kernel can be created via a simple SWAG ("educated guess"). The width of the smoothing kernel should be a little wider than the widest expected "interesting" peak in the original data, and its shape will resemble that peak (a single-scaled wavelet). For mean-preserving kernels (what any good smoothing filter should be) the sum of the kernel elements should be precisely equal to 1.00, and the kernel should be symmetric about its center (meaning it will have an odd number of elements.

Given an optimal smoothing kernel (or a small number of kernels optimized for different data content), the degree of smoothing becomes a scaling factor for (the "gain" of) the convolution kernel.

Determining the "correct" (optimal) degree of smoothing (convolution kernel gain) can even be automated: Compare the standard deviation of the first derivative data with the standard deviation of the smoothed data. How the ratio of the two standard deviations changes with changes in the degree of smoothing cam be used to predict effective smoothing values. A few manual data runs (that are truly representative) should be all that's needed.

All the prior solutions posted above compute the first derivative, but they don't treat it as a statistical measure, nor do the above solutions attempt to performing feature preserving/enhancing smoothing (to help subtle peaks "leap above" the noise).

Finally, the bad news: Finding "real" peaks becomes a royal pain when the noise also has features that look like real peaks (overlapping bandwidth). The next more-complex solution is generally to use a longer convolution kernel (a "wider kernel aperture") that takes into account the relationship between adjacent "real" peaks (such as minimum or maximum rates for peak occurrence), or to use multiple convolution passes using kernels having different widths (but only if it is faster: it is a fundamental mathematical truth that linear convolutions performed in sequence can always be convolved together into a single convolution). But it is often far easier to first find a sequence of useful kernels (of varying widths) and convolve them together than it is to directly find the final kernel in a single step.

Hopefully this provides enough info to let Google (and perhaps a good stats text) fill in the gaps. I really wish I had the time to provide a worked example, or a link to one. If anyone comes across one online, please post it here!

Normally, that is not an error per se; it is a warning that the first file it found that matches the -lPI-Http argument to the compiler/linker is not valid. The error occurs when no other library can be found with the right content.

So, you need to look to see whether /dvlpmnt/libPI-Http.a is a library of 32-bit object files or of 64-bit object files - it will likely be 64-bit if you are compiling with the -m32 option. Then you need to establish whether there is an alternative libPI-Http.a or libPI-Http.so file somewhere else that is 32-bit. If so, ensure that the directory that contains it is listed in a -L/some/where argument to the linker. If not, then you will need to obtain or build a 32-bit version of the library from somewhere.

To establish what is in that library, you may need to do:

mkdir junk
cd junk
ar x /dvlpmnt/libPI-Http.a
file *.o
cd ..
rm -fr junk

The 'file' step tells you what type of object files are in the archive. The rest just makes sure you don't make a mess that can't be easily cleaned up.

I found that calling git is rather slow (any of the subcommands), especially for updating the prompt. Time varies between .1 and .2 seconds within the root dir of a repo, and over .2 seconds outside a repo, on a top notch machine (raid 1, 8 gb ram, 8 hardware threads). It does run Cygwin, though.

Therefore I wrote this script for speed:

#!/usr/bin/perl

$cwd=$ENV{PWD}; #`pwd`;
chomp $cwd;

while (length $cwd)
{
        -d "$cwd/.git" and do {
                -f "$cwd/.git/HEAD" and do {
                        open IN, "<", "$cwd/.git/HEAD";
                        $_=<IN>;
                        close IN;
                        s@ref: refs/heads/@@;
                        print $_;
                };
                exit;
        };

        $cwd=~s@/[^/]*$@@;
}

May need some tweaking.

The well-known JAXB

There is a maven plugin that could do this for you at any build phase you want.

You could do this stuff in both ways: xsd <-> Java

• Some daemons (e.g. apache) do this by themselves by calling setuid()
• You could use the setuid-file flag to run the process as a different user.
• Of course, the solution you mentioned works as well.

If you intend to write your own daemon, then I recommend calling setuid(). This way, your process can

1. Make use of its root privileges (e.g. open log files, create pid files).
2. Drop its root privileges at a certain point during startup.

This answer is 33 times faster than @Escualo assuming that the list is very large, and assuming that it's already an np.array(). I had to turn down the number of test runs because the test is looking at 10000000 elements not just 100.

import random
from datetime import datetime
import operator
import numpy as np

def explicit(l):
    max_val = max(l)
    max_idx = l.index(max_val)
    return max_idx, max_val

def implicit(l):
    max_idx, max_val = max(enumerate(l), key=operator.itemgetter(1))
    return max_idx, max_val

def npmax(l):
    max_idx = np.argmax(l)
    max_val = l[max_idx]
    return (max_idx, max_val)

if __name__ == "__main__":
    from timeit import Timer

t = Timer("npmax(l)", "from __main__ import explicit, implicit, npmax; "
      "import random; import operator; import numpy as np;"
      "l = np.array([random.random() for _ in xrange(10000000)])")
print "Npmax: %.2f msec/pass" % (1000  * t.timeit(number=10)/10 )

t = Timer("explicit(l)", "from __main__ import explicit, implicit; "
      "import random; import operator;"
      "l = [random.random() for _ in xrange(10000000)]")
print "Explicit: %.2f msec/pass" % (1000  * t.timeit(number=10)/10 )

t = Timer("implicit(l)", "from __main__ import explicit, implicit; "
      "import random; import operator;"
      "l = [random.random() for _ in xrange(10000000)]")
print "Implicit: %.2f msec/pass" % (1000  * t.timeit(number=10)/10 )

Results on my computer:

Npmax: 8.78 msec/pass
Explicit: 290.01 msec/pass
Implicit: 790.27 msec/pass

Just to make for a complete answer, if your html content is in a component variable, you could also use:

<div [innerHTML]=componentVariableThatHasTheHtml></div>

I make aggressive use of the subset parameter with selection of only the required variables when passing dataframes to the data= argument of regression functions. It does result in some errors if I forget to add variables to both the formula and the select= vector, but it still saves a lot of time due to decreased copying of objects and reduces the memory footprint significantly. Say I have 4 million records with 110 variables (and I do.) Example:

# library(rms); library(Hmisc) for the cph,and rcs functions
Mayo.PrCr.rbc.mdl <- 
cph(formula = Surv(surv.yr, death) ~ age + Sex + nsmkr + rcs(Mayo, 4) + 
                                     rcs(PrCr.rat, 3) +  rbc.cat * Sex, 
     data = subset(set1HLI,  gdlab2 & HIVfinal == "Negative", 
                           select = c("surv.yr", "death", "PrCr.rat", "Mayo", 
                                      "age", "Sex", "nsmkr", "rbc.cat")
   )            )

By way of setting context and the strategy: the gdlab2 variable is a logical vector that was constructed for subjects in a dataset that had all normal or almost normal values for a bunch of laboratory tests and HIVfinal was a character vector that summarized preliminary and confirmatory testing for HIV.

You could store intermediate values in a cell or column (which you could hide if you choose)

C1: = VLOOKUP(A1, B:B, 1, 0)
D1: = IF(C1 > 10, C1 - 10, C1)

Solution:

SUBSTRING(sys.fn_sqlvarbasetostr(HASHBYTES('MD5','your text')),3,32)

tableB.col1 = tableA.col1 
OR tableB.col2 = tableA.col1  
OR tableB.col1 = tableA.col2  
OR tableB.col1 = tableA.col2

np.max is just an alias for np.amax. This function only works on a single input array and finds the value of maximum element in that entire array (returning a scalar). Alternatively, it takes an axis argument and will find the maximum value along an axis of the input array (returning a new array).

>>> a = np.array([[0, 1, 6],
                  [2, 4, 1]])
>>> np.max(a)
6
>>> np.max(a, axis=0) # max of each column
array([2, 4, 6])

The default behaviour of np.maximum is to take two arrays and compute their element-wise maximum. Here, 'compatible' means that one array can be broadcast to the other. For example:

>>> b = np.array([3, 6, 1])
>>> c = np.array([4, 2, 9])
>>> np.maximum(b, c)
array([4, 6, 9])

But np.maximum is also a universal function which means that it has other features and methods which come in useful when working with multidimensional arrays. For example you can compute the cumulative maximum over an array (or a particular axis of the array):

>>> d = np.array([2, 0, 3, -4, -2, 7, 9])
>>> np.maximum.accumulate(d)
array([2, 2, 3, 3, 3, 7, 9])

This is not possible with np.max.

You can make np.maximum imitate np.max to a certain extent when using np.maximum.reduce:

>>> np.maximum.reduce(d)
9
>>> np.max(d)
9

Basic testing suggests the two approaches are comparable in performance; and they should be, as np.max() actually calls np.maximum.reduce to do the computation.

As @MatrixFrog pointed out in their comment, if the goal is to edit the config, you might want to run:

git config --global --edit

This command will open the config file (in this case, the --global one) in the editor of choice, and await for the file to be closed (just like during git rebase -i).

def DecodedCharArrayFromByteStreamIn(stringStreamIn):
    #turn string values into opererable numeric byte values
    byteArray = [ord(character) for character in stringStreamIn]
    datalength = byteArray[1] & 127
    indexFirstMask = 2 
    if datalength == 126:
        indexFirstMask = 4
    elif datalength == 127:
        indexFirstMask = 10
    masks = [m for m in byteArray[indexFirstMask : indexFirstMask+4]]
    indexFirstDataByte = indexFirstMask + 4
    decodedChars = []
    i = indexFirstDataByte
    j = 0
    while i < len(byteArray):
        decodedChars.append( chr(byteArray[i] ^ masks[j % 4]) )

Here's something for those who like beautiful code.

        obj.attachEvent('on'+evt,func);
    }
}

Shamelessly stolen from Iframe-Resizer.

A more efficient method, that uses integer math rather than strings/varchars, that will result in an int type rather than a string type is:

SELECT YYYYMM = (YEAR(GETDATE()) * 100) + MONTH(GETDATE())

Adds two zeros to the right side of the year and then adds the month to the added two zeros.

give z-index:-1 to flash and give z-index:100 to div..

1. To read input:

   Scanner scanner = new Scanner(System.in);
   String input = scanner.nextLine();
   

2. To read input when you call a method with some arguments/parameters:

   if (args.length != 2) {
       System.err.println("Utilizare: java Grep <fisier> <cuvant>");
       System.exit(1);
   }
   try {
       grep(args[0], args[1]);
   } catch (IOException e) {
       System.out.println(e.getMessage());
   }
   

The easiest (and standard) way to install Android SDK under OS X is to use brew.

brew install android-sdk

If you do not have homebrew, here's how to get it.

This will install Android SDK into /usr/local/Cellar/android-sdk/ and, at this moment, this is the best location to install it.

If you came here searching OpenID Connect (OIDC): OAuth 2.0 != OIDC

I recognize that this is tagged for oauth 2.0 and NOT OIDC, however there is frequently a conflation between the 2 standards since both standards can use JWTs and the aud claim. And one (OIDC) is basically an extension of the other (OAUTH 2.0). (I stumbled across this question looking for OIDC myself.)

OAuth 2.0 Access Tokens##

For OAuth 2.0 Access tokens, existing answers pretty well cover it. Additionally here is one relevant section from OAuth 2.0 Framework (RFC 6749)

For public clients using implicit flows, this specification does not provide any method for the client to determine what client an access token was issued to.
...
Authenticating resource owners to clients is out of scope for this specification. Any specification that uses the authorization process as a form of delegated end-user authentication to the client (e.g., third-party sign-in service) MUST NOT use the implicit flow without additional security mechanisms that would enable the client to determine if the access token was issued for its use (e.g., audience- restricting the access token).

OIDC ID Tokens##

OIDC has ID Tokens in addition to Access tokens. The OIDC spec is explicit on the use of the aud claim in ID Tokens. (openid-connect-core-1.0)

aud
REQUIRED. Audience(s) that this ID Token is intended for. It MUST contain the OAuth 2.0 client_id of the Relying Party as an audience value. It MAY also contain identifiers for other audiences. In the general case, the aud value is an array of case sensitive strings. In the common special case when there is one audience, the aud value MAY be a single case sensitive string.

furthermore OIDC specifies the azp claim that is used in conjunction with aud when aud has more than one value.

azp
OPTIONAL. Authorized party - the party to which the ID Token was issued. If present, it MUST contain the OAuth 2.0 Client ID of this party. This Claim is only needed when the ID Token has a single audience value and that audience is different than the authorized party. It MAY be included even when the authorized party is the same as the sole audience. The azp value is a case sensitive string containing a StringOrURI value.

I couldnt comment on @Biranchi s post since I dont have enough reputation, but it fixed the problem for me.

One thing to note! If adding changeDetection: ChangeDetectionStrategy.OnPush on the component didn't work, and its a child component (dumb component) try adding it to the parent also.

This fixed the bug, but I wonder what are the side effects of this.

According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.0</version>
</dependency>

Jakarta EE 8 update (Mar 2020)

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>2.3.3</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.3</version>
  <scope>runtime</scope>
</dependency>

Jakarta EE 9 update (Nov 2020)

Use latest release of Eclipse Implementation of JAXB 3.0.0:

• Jakarta EE9 API jakarta.xml.bind-api
• compatible implementation jaxb-impl

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>3.0.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>3.0.0</version>
  <scope>runtime</scope>
</dependency>

Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:

javax.xml.bind -> jakarta.xml.bind

One common use is for template-typedef workaround classes like following:

template <class TObj>
class MyLibrariesSmartPointer
{
  MyLibrariesSmartPointer();
  public:
    typedef smart_ptr<TObj> type;
};

Obviously a public non-implemented constructor would work aswell, but a private construtor raises a compile time error instead of a link time error, if anyone tries to instatiate MyLibrariesSmartPointer<SomeType> instead of MyLibrariesSmartPointer<SomeType>::type, which is desireable.

Use String.fromCharCode. This returns a string from a Unicode value, which matches the first 128 characters of ASCII.

var a = String.fromCharCode(97);

Place the following after the setContentView() method.

final EditText edit =  (EditText) findViewById(R.id.Your_Edit_ID);
String emailString = (String) edit.getText().toString();
Log.d("email",emailString);

Since you have an object, not a jQuery wrapper, you need to use a different variant of $.each()

$.each(json, function (key, data) {
    console.log(key)
    $.each(data, function (index, data) {
        console.log('index', data)
    })
})

Demo: Fiddle

Switching from gcc 4.6 to gcc 4.8 resolved this for me.

If your Objects are containing of Strings only, then you can do it like this:

Map<String,Object> map = new HashMap<String,Object>(); //Object is containing String
Map<String,String> newMap =new HashMap<String,String>();
for (Map.Entry<String, Object> entry : map.entrySet()) {
       if(entry.getValue() instanceof String){
            newMap.put(entry.getKey(), (String) entry.getValue());
          }
 }

If every Objects are not String then you can replace (String) entry.getValue() into entry.getValue().toString().

What does this record marking mean? If this is used only for logging purposes, I would use GET and disable all caching, since you want to log every query for this resources. If record marking has another purpose, POST is the way to go. User should know, that his actions effect the system and POST method is a warning.

What you may want to do is include a script on all pages that does the following ... 1. find the youtube-iframe : searching for it by width and height by title or by finding www.youtube.com in its source. You can do that by ... - looping through the window.frames by a for-in loop and then filter out by the properties

1. inject jscript in the iframe of the current page adding the onYoutubePlayerReady must-include-function http://shazwazza.com/post/Injecting-JavaScript-into-other-frames.aspx

2. Add the event listeners etc..

Hope this helps

New thread #92459 Exception in thread "main" java.lang.OutOfMemoryError: unable to create new native thread

i7-7700 16gb ram

Here is how you might do it with generics:

public T GetAnything<T>()
{
   T t = //Code to create instance

   return t;
}

But you would have to know what type you wanted returned at design time. And that would mean that you could just call a different method for each creation...

Here is what you need to do:

1. Get the Apache HttpClient, this would enable you to make the required request
2. Create an HttpPost request with it and add the header application/x-www-form-urlencoded
3. Create a StringEntity that you will pass JSON to it
4. Execute the call

The code roughly looks like (you will still need to debug it and make it work):

// @Deprecated HttpClient httpClient = new DefaultHttpClient();
HttpClient httpClient = HttpClientBuilder.create().build();
try {
    HttpPost request = new HttpPost("http://yoururl");
    StringEntity params = new StringEntity("details={\"name\":\"xyz\",\"age\":\"20\"} ");
    request.addHeader("content-type", "application/x-www-form-urlencoded");
    request.setEntity(params);
    HttpResponse response = httpClient.execute(request);
} catch (Exception ex) {
} finally {
    // @Deprecated httpClient.getConnectionManager().shutdown(); 
}

With ECMAScript 6 there is a better way.

You can use computed property names in object property definitions, for example:

var name1 = 'John'; 
var value1 = '42'; 
var name2 = 'Sarah'; 
var value2 = '35';

var ipID = { 
             [name1] : value1, 
             [name2] : value2 
           }

This is equivalent to the following, where you have variables for the property names.

var ipID = { 
             John: '42', 
             Sarah: '35' 
           }

Use REPLACE:

SELECT REPLACE(t.column, 'est1', 'rest1')
  FROM MY_TABLE t

If you want to update the values in the table, use:

UPDATE MY_TABLE t
   SET column = REPLACE(t.column, 'est1', 'rest1')

If you are trying to compile these codes from a Linux terminal, you might get an error saying

expects argument type int

Its because, when you try to get the memory address by printf, you cannot specify it as %d as its shown in the video. Instead of that try to put %p.

Example:

// this might works fine since the out put is an integer as its expected.
printf("%d\n", *p); 

// but to get the address:
printf("%p\n", p); 

For hibernate it is important to know that your object WILL have an id, when you want to persist/save it. Thus, make sure that

    private String U_id;

will have a value, by the time you are going to persist your object. You can do that with the @GeneratedValue annotation or by assigning a value manually.

In the case you need or want to assign your id's manually (and that's what the above error is actually about), I would prefer passing the values for the fields to your constructor, at least for U_id, e.g.

  public Role (String U_id) { ... }

This ensures that your object has an id, by the time you have instantiated it. I don't know what your use case is and how your application behaves in concurrency, however, in some cases this is not recommended. You need to ensure that your id is unique.

Further note: Hibernate will still require a default constructor, as stated in the hibernate documentation. In order to prevent you (and maybe other programmers if you're designing an api) of instantiations of Role using the default constructor, just declare it as private.

I landed here through google, and I actually believe I've found a way to gain a fully functioning root promt in cygwin.

Here are my steps.

First you need to rename the Windows Administrator account to "root" Do this by opening start manu and typing "gpedit.msc"

Edit the entry under Local Computer Policy > Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options > Accounts: Rename administrator account

Then you'll have to enable the account if it isn't yet enabled. Local Computer Policy > Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options > Accounts: Administrator account status

Now log out and log into the root account.

Now set an environment variable for cygwin. To do that the easy way: Right Click My Computer > Properties

Click (on the left sidebar) "Advanced system settings"

Near the bottom click the "Enviroment Variables" button

Under "System Variables" click the "New..." button

For the name put "cygwin" without the quotes. For the value, enter in your cygwin root directory. ( Mine was C:\cygwin )

Press OK and close all of that to get back to the desktop.

Open a Cygwin terminal (cygwin.bat)

Edit the file /etc/passwd and change the line

Administrator:unused:500:503:U-MACHINE\Administrator,S-1-5-21-12345678-1234567890-1234567890-500:/home/Administrator:/bin/bash

To this (your numbers, and machine name will be different, just make sure you change the highlighted numbers to 0!)

root:unused:0:0:U-MACHINE\root,S-1-5-21-12345678-1234567890-1234567890-0:/root:/bin/bash

Now that all that is finished, this next bit will make the "su" command work. (Not perfectly, but it will function enough to use. I don't think scripts will function correctly, but hey, you got this far, maybe you can find the way. And please share)

Run this command in cygwin to finalize the deal.

mv /bin/su.exe /bin/_su.exe_backup
cat > /bin/su.bat << "EOF"
@ECHO OFF
RUNAS /savecred /user:root %cygwin%\cygwin.bat
EOF
ln -s /bin/su.bat /bin/su
echo ''
echo 'All finished'

Log out of the root account and back into your normal windows user account.

After all of that, run the new "su.bat" manually by double clicking it in explorer. Enter in your password and go ahead and close the window.

Now try running the su command from cygwin and see if everything worked out alright.

If you use docker in your dev you can do this in another shell: docker attach running_node_app_container_name

That will show you STDOUT and STDERR.

From the MSDN page on StackOverflowExceptions:

In prior versions of the .NET Framework, your application could catch a StackOverflowException object (for example, to recover from unbounded recursion). However, that practice is currently discouraged because significant additional code is required to reliably catch a stack overflow exception and continue program execution.

Starting with the .NET Framework version 2.0, a StackOverflowException object cannot be caught by a try-catch block and the corresponding process is terminated by default. Consequently, users are advised to write their code to detect and prevent a stack overflow. For example, if your application depends on recursion, use a counter or a state condition to terminate the recursive loop. Note that an application that hosts the common language runtime (CLR) can specify that the CLR unload the application domain where the stack overflow exception occurs and let the corresponding process continue. For more information, see ICLRPolicyManager Interface and Hosting the Common Language Runtime.

If you want to print output of anything in Bash without end of line, you echo it with the -n switch.

If you have it in a variable already, then echo it with the trailing newline cropped:

$ testvar=$(wc -l < log.txt)
$ echo -n $testvar

Or you can do it in one line, instead:

$ echo -n $(wc -l < log.txt)

If your your list is dynamically generated with unknown number and your target is to always have last div in a new line set last div class to "col-xl-12" and remove other classes so it will always take a full row.

This is a copy of your code corrected so that last div always occupy a full row (I although removed unnecessary classes).

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet">_x000D_
<div class="grid">_x000D_
  <div class="row">_x000D_
    <div class="col-sm-3">Under me should be a DIV</div>_x000D_
    <div class="col-md-6 col-sm-5">Under me should be a DIV</div>_x000D_
    <div class="col-xl-12">I am the last DIV and I always take a full row for my self!!</div>_x000D_
  </div>_x000D_
</div>

You can actually still use ".css" and apply css transitions to the div being affected. So continue using ".css" and add the below styles to your stylesheet for "#hfont1". Since ".css" allows for a lot more properties than ".animate", this is always my preferred method.

#hfont1 {
    -webkit-transition: width 0.4s;
    transition: width 0.4s;
}

Following code worked for me:

     git fetch
     git checkout <branch from which file needs to be fetched> <filepath> 

ngOnInit() is called after ngOnChanges() was called the first time. ngOnChanges() is called every time inputs are updated by change detection.

ngAfterViewInit() is called after the view is initially rendered. This is why @ViewChild() depends on it. You can't access view members before they are rendered.

I've wondered this myself for years. But i came across a good reason today.

Imagine a file with a record on every line (ex: a CSV file). And that the computer was writing records at the end of the file. But it suddenly crashed. Gee was the last line complete? (not a nice situation)

But if we always terminate the last line, then we would know (simply check if last line is terminated). Otherwise we would probably have to discard the last line every time, just to be safe.

You can use transitions to delay the :hover effect you want, if the effect is CSS-based.

For example

div{
    transition: 0s background-color;
}

div:hover{
    background-color:red;    
    transition-delay:1s;
}

this will delay applying the the hover effects (background-color in this case) for one second.

Demo of delay on both hover on and off:

div{_x000D_
    display:inline-block;_x000D_
    padding:5px;_x000D_
    margin:10px;_x000D_
    border:1px solid #ccc;_x000D_
    transition: 0s background-color;_x000D_
    transition-delay:1s;_x000D_
}_x000D_
div:hover{_x000D_
    background-color:red;_x000D_
}

<div>delayed hover</div>

Demo of delay only on hover on:

div{_x000D_
    display:inline-block;_x000D_
    padding:5px;_x000D_
    margin:10px;_x000D_
    border:1px solid #ccc;_x000D_
    transition: 0s background-color;_x000D_
}_x000D_
div:hover{_x000D_
    background-color:red;    _x000D_
    transition-delay:1s;_x000D_
}

<div>delayed hover</div>

Display array in beautiful way:

function arrayDisplay($input)
{
    return implode(
        ', ',
        array_map(
            function ($v, $k) {
                return sprintf("%s => '%s'", $k, $v);
            },
            $input,
            array_keys($input)
        )
    );
}

$arr = array('foo'=>'bar',
              'baz'=>'boom',
              'cow'=>'milk',
              'php'=>'hypertext processor');

echo arrayDisplay($arr);

Displays:

foo => 'bar', baz => 'boom', cow => 'milk', php => 'hypertext processor'

To put it in another way, can we replicate the appearance of these text views without using the android:textAppearance attribute?

Like biegleux already said:

• small represents 14sp
• medium represents 18sp
• large represents 22sp

If you want to use the small, medium or large value on any text in your Android app, you can just create a dimens.xml file in your values folder and define the text size there with the following 3 lines:

<dimen name="text_size_small">14sp</dimen>
<dimen name="text_size_medium">18sp</dimen>
<dimen name="text_size_large">22sp</dimen>

Here is an example for a TextView with large text from the dimens.xml file:

<TextView
  android:id="@+id/hello_world"
  android:text="hello world"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:textSize="@dimen/text_size_large"/>

To set it for the current session, do:

SET time_zone = timezonename;

This should get you started:

R> qplot(hwy, cty, data = mpg) + 
       facet_grid(. ~ manufacturer) + 
       theme(strip.text.x = element_text(size = 8, colour = "orange", angle = 90))

See also this question: How can I manipulate the strip text of facet plots in ggplot2?

Check out history.js. There is a html 5 statechange event and you can listen to it.

To set short tags to open from a Vagrant install script on Ubuntu:

sed -i "s/short_open_tag = .*/short_open_tag = On/" /etc/php5/apache2/php.ini

I just needed a simple testing button for react.js. Here is what I did and it worked.

function Testing(){
 var f=function testing(){
         console.log("Testing Mode activated");
         UserData.authenticated=true;
         UserData.userId='123';
       };
 console.log("Testing Mode");

 return (<div><button onClick={f}>testing</button></div>);
}

Actually when you use type="number" your input control populate with up/down arrow to increment/decrement numeric value, so when you update textbox value with those button it will not pass limit of 100, but when you manually give input like 120/130 and so on, it will not validate for max limit, so you have to validate it by code.

You can disable manual input OR you have to write some code on valueChange/textChange/key* event.

What ended up finally working for me was to add the remote repository name to the git fetch command, like this:

git fetch core

Now you can see all of them like this:

git branch --all

Try using COUNT function like this

=IF(COUNT(SEARCH({"Romney","Obama","Gingrich"},C1)),1,"")

Note that you don't need the wildcards (as teylyn says) and unless there's a specific reason "1" doesn't need quotes (in fact that makes it a text value)

If you have this statement..

View view = inflater.inflate(R.layout.fragment1, container);//may be Incorrect 

Then try this.. Add false as third argument.. May be it could help..

View view = inflater.inflate(R.layout.fragment1, container, false);//correct one

You can call more of 1 function filters in the same ng-repeat filter

<article data-ng-repeat="result in results | filter:search() | filter:filterFn()" class="result">

If your project's source code has import statements that reference classes that are in widget.jar, you should add the jar to your projects Compile-time Libraries. (The jar widget.jar will automatically be added to your project's Run-time Libraries). That corresponds to (1).

If your source code has imports for classes in some other jar and the source code for those classes has import statements that reference classes in widget.jar, you should add widget.jar to the Run-time libraries list. That corresponds to (2).

You can add the jars directly to the Libraries list in the project properties. You can also create a Library that contains the jar file and then include that Library in the Compile-time or Run-time Libraries list.

If you create a NetBeans Library for widget.jar, you can also associate source code for the jar's content and Javadoc for the APIs defined in widget.jar. This additional information about widget.jar will be used by NetBeans as you debug code. It will also be used to provide addition information when you use code completion in the editor.

You should avoid using Tools >> Java Platform to add a jar to a project. That dialog allows you to modify the classpath that is used to compile and run all projects that use the Java Platform that you create. That may be useful at times but hides your project's dependency on widget.jar almost completely.

You literally just pass them in std::thread(func1,a,b,c,d); that should have compiled if the objects existed, but it is wrong for another reason. Since there is no object created you cannot join or detach the thread and the program will not work correctly. Since it is a temporary the destructor is immediately called, since the thread is not joined or detached yet std::terminate is called. You could std::join or std::detach it before the temp is destroyed, like std::thread(func1,a,b,c,d).join();//or detach .

This is how it should be done.

std::thread t(func1,a,b,c,d);
t.join();  

You could also detach the thread, read-up on threads if you don't know the difference between joining and detaching.

you can raise the click event on an element by doing

// this must be done after input1 exists in the DOM
var element = document.getElementById("input1");

if (element) element.click();

The easiest way that I found to fix this is to uninstall everything then install a specific version of tensorflow-gpu:

1. uninstall tensorflow:

    pip uninstall tensorflow

2. uninstall tensorflow-gpu: (make sure to run this even if you are not sure if you installed it)

    pip uninstall tensorflow-gpu

3. Install specific tensorflow-gpu version:

    pip install tensorflow-gpu==2.0.0
    pip install tensorflow_hub
    pip install tensorflow_datasets

You can check if this worked by adding the following code into a python file:

from __future__ import absolute_import, division, print_function, unicode_literals

import numpy as np

import tensorflow as tf
import tensorflow_hub as hub
import tensorflow_datasets as tfds

print("Version: ", tf.__version__)
print("Eager mode: ", tf.executing_eagerly())
print("Hub Version: ", hub.__version__)
print("GPU is", "available" if tf.config.experimental.list_physical_devices("GPU") else "NOT AVAILABLE")

Run the file and then the output should be something like this:

Version:  2.0.0
Eager mode:  True
Hub Version:  0.7.0
GPU is available

Maybe it's is completely possible with only CSS but I prefer to avoid "float" as much as I can because it interferes with it's parent's height.

If you are using jQuery, you can create a simple `wrapN` plugin that is similar to `wrapAll` except it only wraps "N" elements and then breaks and wraps the next "N" elements using a loop. Then set your wrappers class to `display: block;`.

(function ($) {
    $.fn.wrapN = function (wrapper, n, start) {
        if (wrapper === undefined || n === undefined) return false;
        if (start === undefined) start = 0;
        for (var i = start; i < $(this).size(); i += n)
           $(this).slice(i, i + n).wrapAll(wrapper);
        return this;
    };
}(jQuery));

$(document).ready(function () {
    $("li").wrapN("<span class='break' />", 3);
});

Deletion of a topic has been supported since 0.8.2.x version. You have to enable topic deletion (setting delete.topic.enable to true) on all brokers first.

Note: Ever since 1.0.x, the functionality being stable, delete.topic.enable is by default true.

Follow this step by step process for manual deletion of topics

1. Stop Kafka server
2. Delete the topic directory, on each broker (as defined in the logs.dirs and log.dir properties) with rm -rf command
3. Connect to Zookeeper instance: zookeeper-shell.sh host:port
4. From within the Zookeeper instance:
   1. List the topics using: ls /brokers/topics
   2. Remove the topic folder from ZooKeeper using: rmr /brokers/topics/yourtopic
   3. Exit the Zookeeper instance (Ctrl+C)
5. Restart Kafka server
6. Confirm if it was deleted or not by using this command kafka-topics.sh --list --zookeeper host:port

There is no compiler independent way of doing this, as neither the C (nor the C++) standards say that the floating point math types must support NAN or INF.

Edit: I just checked the wording of the C++ standard, and it says that these functions (members of the templated class numeric_limits):

quiet_NaN() 
signalling_NaN()

wiill return NAN representations "if available". It doesn't expand on what "if available" means, but presumably something like "if the implementation's FP rep supports them". Similarly, there is a function:

infinity() 

which returns a positive INF rep "if available".

These are both defined in the <limits> header - I would guess that the C standard has something similar (probably also "if available") but I don't have a copy of the current C99 standard.

Note that as of Microsoft SQL Server 2016, UTF-8 is supported by bcp, BULK_INSERT, and OPENROWSET.

Addendum 2016-12-21: SQL Server 2016 SP1 now enables Unicode Compression (and most other previously Enterprise-only features) for all versions of MS SQL including Standard and Express. This is not the same as UTF-8 support, but it yields a similar benefit if the goal is disk space reduction for Western alphabets.

Each one is a different type execution.

• ExecuteScalar is going to be the type of query which will be returning a single value.

  An example would be returning a generated id after inserting.

  INSERT INTO my_profile (Address) VALUES ('123 Fake St.'); SELECT CAST(scope_identity() AS int)

• ExecuteReader gives you a data reader back which will allow you to read all of the columns of the results a row at a time.

  An example would be pulling profile information for one or more users.

  SELECT * FROM my_profile WHERE id = '123456'

• ExecuteNonQuery is any SQL which isn't returning values, but is actually performing some form of work like inserting deleting or modifying something.

  An example would be updating a user's profile in the database.

  UPDATE my_profile SET Address = '123 Fake St.' WHERE id = '123456'

There doesn't seem to be a standardized default value. I have the feeling the default is 0, and the timeout event left totally dependent on browser and network settings.

For IE, there is a timeout property for XMLHTTPRequests here. It defaults to null, and it says the network stack is likely to be the first to time out (which will not generate an ontimeout event by the way).

I had this problem and the issue was that I had the package loaded in another R instance. Simply closing all R instances and installing on a fresh instance allowed for the package to be installed.

Generally, you can also install if every remaining instance has never loaded the package as well (even if it installed an old version).

function cool(d)_x000D_
{_x000D_
    alert(d.value.length);_x000D_
}

<input type="text" value="" onblur="cool(this)">

It will return the length of string

Instead of blur use keydown event.

you can use setAttribute function in Model to add a custom attribute

Note that it is now possible to use some of C++11 std::thread in the win32 threading mode. These header-only adapters worked out of the box for me: https://github.com/meganz/mingw-std-threads

From the revision history it looks like there is some recent attempt to make this a part of the mingw64 runtime.

The most likely reason for the error is that the certificate authority that issued your SSL certificate is trusted on your desktop, but not on your mobile.

If you purchased the certificate from a common certification authority, it shouldn't be an issue - but if it is a less common one it is possible that your phone doesn't have it. You may need to accept it as a trusted publisher (although this is not ideal if you are pushing the site to the public as they won't be willing to do this.)

You might find looking at a list of Trusted CAs for Android helps to see if yours is there or not.

Simple 2020 no-tricks method:

body {
    display: flex;
    flex-direction: column;
}

#footer {
    margin-top: auto;
}

It's looking for the file in the current directory.

First, go to that directory

cd /users/gcameron/Desktop/map

And then try to run it

python colorize_svg.py

Please add the correct mime-types to your code - at least these ones:

.jpeg -> image/jpeg
.gif  -> image/gif
.png  -> image/png

A list of mime-types can be found here.

Furthermore, simplify the code's logic and report an error number to help the first level support track down problems:

$allowedExts = array(
  "pdf", 
  "doc", 
  "docx"
); 

$allowedMimeTypes = array( 
  'application/msword',
  'text/pdf',
  'image/gif',
  'image/jpeg',
  'image/png'
);

$extension = end(explode(".", $_FILES["file"]["name"]));

if ( 20000 < $_FILES["file"]["size"]  ) {
  die( 'Please provide a smaller file [E/1].' );
}

if ( ! ( in_array($extension, $allowedExts ) ) ) {
  die('Please provide another file type [E/2].');
}

if ( in_array( $_FILES["file"]["type"], $allowedMimeTypes ) ) 
{      
 move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $_FILES["file"]["name"]); 
}
else
{
die('Please provide another file type [E/3].');
}

as @chepner says in his comment you are comparing $i to a fixed string.

To expand and rectify the situation you should use [[ ]] with the regex operator =~

eg:

for i in $(ls);do
    if [[ $i =~ .*\.java$ ]];then
        echo "I want to do something with the file $i"
    fi
done

the regex to the right of =~ is tested against the value of the left hand operator and should not be quoted, ( quoted will not error but will compare against a fixed string and so will most likely fail"

but @chepner 's answer above using glob is a much more efficient mechanism.

Some formats, like PNG which is lossless, will ignore the quality setting.

Application Programming Interface is a set of routines/data structures/classes which specifies a way to interact with the target platform/software like OS X, Android, project management application, virtualization software etc.

While Software Development Kit is a wrapper around API/s that makes the job easy for developers.

For example, Android SDK facilitates developers to interact with the Android platform as a whole while the platform itself is built by composite software components communicating via APIs.

Also, sometimes SDKs are built to facilitate development in a specific programming language. For example, Selenium web driver (built in Java) provides APIs to drive any browser natively, while capybara can be considered an an SDK that facilitates Ruby developers to use Selenium web driver. However, Selenium web driver is also an SDK by itself as it combines interaction with various native browser drivers into one package.

I ended up doing something like this for AngularJS in case someone stumbles across this question:

const imageElem = angular.element('#awardImg');

if (imageElem[0].files[0])
    vm.award.imageElem = imageElem;
    vm.award.image = imageElem[0].files[0];

And then:

if (vm.award.imageElem)
    $('#awardImg').replaceWith(vm.award.imageElem);
    delete vm.award.imageElem;

/* create new name file */
$filename   = uniqid() . "-" . time(); // 5dab1961e93a7-1571494241
$extension  = pathinfo( $_FILES["file"]["name"], PATHINFO_EXTENSION ); // jpg
$basename   = $filename . "." . $extension; // 5dab1961e93a7_1571494241.jpg

$source       = $_FILES["file"]["tmp_name"];
$destination  = "../img/imageDirectory/{$basename}";

/* move the file */
move_uploaded_file( $source, $destination );

echo "Stored in: {$destination}";

if you want to choose dynamically the path to the log file use the method written in this link: method to dynamic choose the log file path.

if you want you can set the path to where your app EXE file exists like this -

var logFileLocation = System.IO.Path.GetDirectoryName
(System.Reflection.Assembly.GetEntryAssembly().Location);

and then send this 'logFileLocation' to the method written in the link above like this:

Initialize(logFileLocation);

and you are ready to go! :)

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

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

Please see the comments.

Code:

import subprocess


class MyLibrary(object):

    def execute(self, cmd):
        return subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, universal_newlines=True,)
      
    def list(self):
        command = ["ping", "google.com"]
        sp = self.execute(command)
        status = sp.wait()  # will wait for sp to finish
        out, err = sp.communicate()
        print(out)
        return status # 0 is success else error

This should do it:

var newClass = window.location.href;
newClass = newClass.substring(newClass.lastIndexOf('/')+1, 5);
$('body').addClass(newClass);

The whole "five characters" thing is a little worrisome; that kind of arbitrary cutoff is usually a red flag. I'd recommend catching everything until an _ or .:

newClass = newClass.match(/\/[^\/]+(_|\.)[^\/]+$/);

That pattern should yield the following:

• ../about_us.html : about
• ../something.html : something
• ../has_two_underscores.html : has

Never mind -- I'm an idiot. I just needed <xsl:value-of select="/root/Image/node()"/>

Yes, #id selectors combined with a multiple selector (comma) is perfectly valid in both jQuery and CSS.

However, for your example, since <script> comes before the elements, you need a document.ready handler, so it waits until the elements are in the DOM to go looking for them, like this:

<script>
  $(function() {
    $("#segement1,#segement2,#segement3").hide()
  });
</script>

<div id="segement1"></div>
<div id="segement2"></div>
<div id="segement3"></div>

I'm using if for day-to-day work and I find it stable. Lately the plugin has made good progress and has added:

• merge support, including a in-Eclipse merge tool;
• a basic synchronise view;
• reading of .git/info/exclude and .gitignore files.
• rebasing;
• streamlined commands for pushing and pulling;
• cherry-picking.

Be sure to skim the EGit User Guide for a good overview of the current functionality.

I find that I only need to drop to the comand line for interactive rebases.

As an official Eclipse project I am confident that EGit will receive all the main features of the command-line client.

Sounds like you're calling sp_executesql with a VARCHAR statement, when it needs to be NVARCHAR.

e.g. This will give the error because @SQL needs to be NVARCHAR

DECLARE @SQL VARCHAR(100)
SET @SQL = 'SELECT TOP 1 * FROM sys.tables'
EXECUTE sp_executesql @SQL

So:

DECLARE @SQL NVARCHAR(100)
SET @SQL = 'SELECT TOP 1 * FROM sys.tables'
EXECUTE sp_executesql @SQL

my approach works without a library and with cropped maps. Means it works with just parts from a Mercator image. Maybe it helps somebody: https://stackoverflow.com/a/10401734/730823

In python many things are iterable including files and strings. Iterating over a filehandler gives you a list of all the lines in that file. Iterating over a string gives you a list of all the characters in that string.

charsFromFile = []
filePath = r'path\to\your\file.txt' #the r before the string lets us use backslashes

for line in open(filePath):
    for char in line:
        charsFromFile.append(char) 
        #apply code on each character here

or if you want a one liner

#the [0] at the end is the line you want to grab.
#the [0] can be removed to grab all lines
[list(a) for a in list(open('test.py'))][0]  

.

.

Edit: as agf mentions you can use itertools.chain.from_iterable

His method is better, unless you want the ability to specify which lines to grab list(itertools.chain.from_iterable(open(filename, 'rU)))

This does however require one to be familiar with itertools, and as a result looses some readablity

If you only want to iterate over the chars, and don't care about storing a list, then I would use the nested for loops. This method is also the most readable.

You can do it in following ways;

1. You can go to control panel/cpanel and add host % It means now the database server can be accessed from your local machine. Now you can install and use MySQL Administrator or Navicat to import and export database with out using PHP-Myadmin, I used it several times to upload 200 MB to 500 MB of data with no issues

2. Use gzip, bzip2 compressions for exporting and importing. I am using PEA ZIP software (free) in Windows. Try to avoid Winrar and Winzip

3. Use MySQL Splitter that splits up the sql file into several parts. In my personal suggestion, Not recommended

4. Using PHP INI setting (dynamically change the max upload and max execution time) as already mentioned by other friends is fruitful but not always.

Just use special `

var lyrics = 'Never gonna give you up';
var html = `<div>${lyrics}</div>`;

You can see more examples here.

I used [self dismissViewControllerAnimated: YES completion: nil]; which will return you to the calling ViewController.

I would recommend while (1) { } or while (true) { }. It's what most programmers would write, and for readability reasons you should follow the common idioms.

(Ok, so there is an obvious "citation needed" for the claim about most programmers. But from the code I've seen, in C since 1984, I believe it is true.)

Any reasonable compiler would compile all of them to the same code, with an unconditional jump, but I wouldn't be surprised if there are some unreasonable compilers out there, for embedded or other specialized systems.

For those who are getting to this question via google... this error can also happen if you try to rename a field that is acting as a foreign key.

There is a patch for the sourcecode of minidlna at sourceforge available that does not make a full rescan, but a kind of incremental scan. That worked fine, but with some later version, the patch is broken. See here Link to SF

MyList.OrderBy(x => x.StartDate).ThenByDescending(x => x.EndDate);

Note that you can use as well the Descending keyword in the OrderBy (in case you need). So another possible answer is:

MyList.OrderByDescending(x => x.StartDate).ThenByDescending(x => x.EndDate);

I don't know that much about batch files but couldn't you have a pre-made batch file copied from the home directory to the path you have that would return a list of the names of the files then use that name?

Here is a link I think might be helpful in making the pre-made batch file.

To avoid the "The directory is not empty" errors of the accepted answer, simply use the good old DOS command as suggested before. The full PS syntax ready for copy-pasting is:

URL -- Uniform Resource Locator

Contains information about how to fetch a resource from its location. For example:

• http://example.com/mypage.html
• ftp://example.com/download.zip
• mailto:[email protected]
• file:///home/user/file.txt
• http://example.com/resource?foo=bar#fragment
• /other/link.html (A relative URL, only useful in the context of another URL)

URLs always start with a protocol (http) and usually contain information such as the network host name (example.com) and often a document path (/foo/mypage.html). URLs may have query parameters and fragment identifiers.

URN -- Uniform Resource Name

Identifies a resource by name. It always starts with the prefix urn: For example:

• urn:isbn:0451450523 to identify a book by its ISBN number.
• urn:uuid:6e8bc430-9c3a-11d9-9669-0800200c9a66 a globally unique identifier
• urn:publishing:book - An XML namespace that identifies the document as a type of book.

URNs can identify ideas and concepts. They are not restricted to identifying documents. When a URN does represent a document, it can be translated into a URL by a "resolver". The document can then be downloaded from the URL.

URI -- Uniform Resource Identifier

URIs encompasses both URLs, URNs, and other ways to indicate a resource.

An example of a URI that is neither a URL nor a URN would be a data URI such as data:,Hello%20World. It is not a URL or URN because the URI contains the data. It neither names it, nor tells you how to locate it over the network.

There are also uniform resource citations (URCs) that point to meta data about a document rather than to the document itself. An example of a URC would be an indicator for viewing the source code of a web page: view-source:http://example.com/. A URC is another type of URI that is neither URL nor URN.

Frequently Asked Questions

I've heard that I shouldn't say URL anymore, why?

The w3 spec for HTML says that the href of an anchor tag can contain a URI, not just a URL. You should be able to put in a URN such as <a href="urn:isbn:0451450523">. Your browser would then resolve that URN to a URL and download the book for you.

Do any browsers actually know how to fetch documents by URN?

Not that I know of, but modern web browser do implement the data URI scheme.

Can a URI be both a URL and a URN?

Good question. I've seen lots of places on the web that state this is true. I haven't been able to find any examples of something that is both a URL and a URN. I don't see how it is possible because a URN starts with urn: which is not a valid network protocol.

Does the difference between URL and URI have anything to do with whether it is relative or absolute?

No. Both relative and absolute URLs are URLs (and URIs.)

Does the difference between URL and URI have anything to do with whether it has query parameters?

No. Both URLs with and without query parameters are URLs (and URIs.)

Does the difference between URL and URI have anything to do with whether it has a fragment identifier?

No. Both URLs with and without fragment identifiers are URLs (and URIs.)

Is a tel: URI a URL or a URN?

For example tel:1-800-555-5555. It doesn't start with urn: and it has a protocol for reaching a resource over a network. It must be a URL.

But doesn't the w3C now say that URLs and URIs are the same thing?

Yes. The W3C realized that there is a ton of confusion about this. They issued a URI clarification document that says that it is now OK to use URL and URI interchangeably. It is no longer useful to strictly segment URIs into different types such as URL, URN, and URC.

On Android 4.1 and higher, you can set your application's content to appear behind the status bar, so that the content doesn't resize as the status bar hides and shows. To do this, use SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN. You may also need to use SYSTEM_UI_FLAG_LAYOUT_STABLE to help your app maintain a stable layout.

When you use this approach, it becomes your responsibility to ensure that critical parts of your app's UI (for example, the built-in controls in a Maps application) don't end up getting covered by system bars. This could make your app unusable. In most cases you can handle this by adding the android:fitsSystemWindows attribute to your XML layout file, set to true. This adjusts the padding of the parent ViewGroup to leave space for the system windows. This is sufficient for most applications.

In some cases, however, you may need to modify the default padding to get the desired layout for your app. To directly manipulate how your content lays out relative to the system bars (which occupy a space known as the window's "content insets"), override fitSystemWindows(Rect insets). The fitSystemWindows() method is called by the view hierarchy when the content insets for a window have changed, to allow the window to adjust its content accordingly. By overriding this method you can handle the insets (and hence your app's layout) however you want.

This tries to improve print_r() output formatting in console applications:

function pretty_printr($array) {

  $string = print_r($array, TRUE);

  foreach (preg_split("/((\r?\n)|(\r\n?))/", $string) as $line) {

    $trimmed_line = trim($line);

    // Skip useless lines.
    if (!$trimmed_line || $trimmed_line === '(' || $trimmed_line === ')' || $trimmed_line === 'Array') {
      continue;
    }

    // Improve lines ending with empty values.
    if (substr_compare($trimmed_line, '=>', -2) === 0) {
      $line .=  "''";
    }

    print $line . PHP_EOL;
  }
}

Example:

[allow_organisation_contact] => 1
[cover_media] => Array
        [image] => Array
                [url] => ''

No, it's not possible.

It's really, if not use native selects, if you create custom select widget from html elements, t.e. "li".

Following solution also provide array of subset which provide specific sum (here sum = 9)

array = [1, 3, 4, 2, 7, 8, 9]

(0..array.size).map { |i| array.combination(i).to_a.select { |a| a.sum == 9 } }.flatten(1)

return array of subsets which return sum of 9

 => [[9], [1, 8], [2, 7], [3, 4, 2]]

Superclass variable = new subclass object();
This just creates an object of type subclass, but assigns it to the type superclass. All the subclasses' data is created etc, but the variable cannot access the subclasses data/functions. In other words, you cannot call any methods or access data specific to the subclass, you can only access the superclasses stuff.

However, you can cast Superclassvariable to the Subclass and use its methods/data.

HashMap operation is dependent factor of hashCode implementation. For the ideal scenario lets say the good hash implementation which provide unique hash code for every object (No hash collision) then the best, worst and average case scenario would be O(1). Let's consider a scenario where a bad implementation of hashCode always returns 1 or such hash which has hash collision. In this case the time complexity would be O(n).

Now coming to the second part of the question about memory, then yes memory constraint would be taken care by JVM.

You are close, but the parameter you pass to SecureStringToBSTR must be a SecureString. You appear to be passing the result of ConvertFrom-SecureString, which is an encrypted standard string. So call ConvertTo-SecureString on this before passing to SecureStringToBSTR.

$SecurePassword = ConvertTo-SecureString $PlainPassword -AsPlainText -Force
$BSTR = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($SecurePassword)
$UnsecurePassword = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR)

Do not use communicate(input=""). It writes input to the process, closes its stdin and then reads all output.

Do it like this:

p=subprocess.Popen(["python","1st.py"],stdin=PIPE,stdout=PIPE)

# get output from process "Something to print"
one_line_output = p.stdout.readline()

# write 'a line\n' to the process
p.stdin.write('a line\n')

# get output from process "not time to break"
one_line_output = p.stdout.readline() 

# write "n\n" to that process for if r=='n':
p.stdin.write('n\n') 

# read the last output from the process  "Exiting"
one_line_output = p.stdout.readline()

What you would do to remove the error:

all_the_process_will_tell_you = p.communicate('all you will ever say to this process\nn\n')[0]

But since communicate closes the stdout and stdin and stderr, you can not read or write after you called communicate.

git log currentbranch..otherbranch will give you the list of commits that will go into the current branch if you do a merge. The usual arguments to log which give details on the commits will give you more information.

git diff currentbranch otherbranch will give you the diff between the two commits that will become one. This will be a diff that gives you everything that will get merged.

Would these help?

For programs you are really better off with a verbatim or alltt environment, but if you want a blank line that LaTeX will not bitch about, try

my line of text blah blah blah\\
\mbox{ }\\  %% space followed by newline
new line of text with blank line between 

Well, the "text-overflow: ellipsis" worked for me, but just if my limit was based on 'width', I has needed a solution that can be applied on lines ( on the'height' instead the 'width' ) so I did this script:

function listLimit (elm, line){
    var maxHeight = parseInt(elm.css('line-Height'))*line;

    while(elm.height() > maxHeight){
        var text = elm.text();
        elm.text(text.substring(0,text.length-10)).text(elm.text()+'...');
    }
}

And when I must, for example, that my h3 has only 2 lines I do :

$('h3').each(function(){
   listLimit ($(this), 2)
})

I dunno if that was the best practice for performance needs, but worked for me.

uname -av;
sudo apt install --reinstall (output from uname -av)

For me this problem occurred because I had a some invalid character in my Groovy script. In our case this was an extra blank line after the closing bracket of the script.

There's a simple command built-in that will pull it:

rvm implode

This will remove the rvm/ directory and all the rubies built within it. In order to remove the final trace of rvm, you need to remove the rvm gem, too:

gem uninstall rvm

If you've made modifications to your PATH you might want to pull those, too. Check your .bashrc, .profile and .bash_profile files, among other things.

You may also have an /etc/rvmrc file, or one in your home directory ~/.rvmrc that may need to be removed as well.

To do it in a generic JPA way using getter annotations, the example below works for me with Hibernate 3.5.4 and Oracle 11g. Note that the mapped getter and setter (getOpenedYnString and setOpenedYnString) are private methods. Those methods provide the mapping but all programmatic access to the class is using the getOpenedYn and setOpenedYn methods.

private String openedYn;

@Transient
public Boolean getOpenedYn() {
  return toBoolean(openedYn);
}

public void setOpenedYn(Boolean openedYn) {
  setOpenedYnString(toYesNo(openedYn));
}

@Column(name = "OPENED_YN", length = 1)
private String getOpenedYnString() {
  return openedYn;
}

private void setOpenedYnString(String openedYn) {
  this.openedYn = openedYn;
}

Here's the util class with static methods toYesNo and toBoolean:

public class JpaUtil {

    private static final String NO = "N";
    private static final String YES = "Y";

    public static String toYesNo(Boolean value) {
        if (value == null)
            return null;
        else if (value)
            return YES;
        else
            return NO;
    }

    public static Boolean toBoolean(String yesNo) {
        if (yesNo == null)
            return null;
        else if (YES.equals(yesNo))
            return true;
        else if (NO.equals(yesNo))
            return false;
        else
            throw new RuntimeException("unexpected yes/no value:" + yesNo);
    }
}

There could be security issues with common methods for auto-login. One of the most easiest ways is documented below:

• Running Putty from the Windows Command Line

And as for the part the executes the command In putty UI, Connection>SSH> there's a field for remote command.

4.17 The SSH panel

The SSH panel allows you to configure options that only apply to SSH sessions.

4.17.1 Executing a specific command on the server

In SSH, you don't have to run a general shell session on the server. Instead, you can choose to run a single specific command (such as a mail user agent, for example). If you want to do this, enter the command in the "Remote command" box. http://the.earth.li/~sgtatham/putty/0.53/htmldoc/Chapter4.html

in short, your answers might just as well be similar to the text below:

• let Putty run command in remote server

One option is to give the <a> a display of inline-block and then apply text-align: center; on the containing block (remove the float as well):

div { 
    background: red;
    overflow: hidden; 
    text-align: center;
}

span a {
    background: #222;
    color: #fff;

As mentioned in "Polling must die: triggering Jenkins builds from a git hook", you can notify Jenkins of a new commit:

With the latest Git plugin 1.1.14 (that I just release now), you can now do this more >easily by simply executing the following command:

curl http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>

This will scan all the jobs that’s configured to check out the specified URL, and if they are also configured with polling, it’ll immediately trigger the polling (and if that finds a change worth a build, a build will be triggered in turn.)

This allows a script to remain the same when jobs come and go in Jenkins.
Or if you have multiple repositories under a single repository host application (such as Gitosis), you can share a single post-receive hook script with all the repositories. Finally, this URL doesn’t require authentication even for secured Jenkins, because the server doesn’t directly use anything that the client is sending. It runs polling to verify that there is a change, before it actually starts a build.

As mentioned here, make sure to use the right address for your Jenkins server:

since we're running Jenkins as standalone Webserver on port 8080 the URL should have been without the /jenkins, like this:

http://jenkins:8080/git/notifyCommit?url=git@gitserver:tools/common.git

To reinforce that last point, ptha adds in the comments:

It may be obvious, but I had issues with:

curl http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>. 

The url parameter should match exactly what you have in Repository URL of your Jenkins job.
When copying examples I left out the protocol, in our case ssh://, and it didn't work.

You can also use a simple post-receive hook like in "Push based builds using Jenkins and GIT"

#!/bin/bash
/usr/bin/curl --user USERNAME:PASS -s \

http://jenkinsci/job/PROJECTNAME/build?token=1qaz2wsx

Configure your Jenkins job to be able to “Trigger builds remotely” and use an authentication token (1qaz2wsx in this example).

However, this is a project-specific script, and the author mentions a way to generalize it.
The first solution is easier as it doesn't depend on authentication or a specific project.

I want to check in change set whether at least one java file is there the build should start.
Suppose the developers changed only XML files or property files, then the build should not start.

Basically, your build script can:

• put a 'build' notes (see git notes) on the first call
• on the subsequent calls, grab the list of commits between HEAD of your branch candidate for build and the commit referenced by the git notes 'build' (git show refs/notes/build): git diff --name-only SHA_build HEAD.
• your script can parse that list and decide if it needs to go on with the build.
• in any case, create/move your git notes 'build' to HEAD.

May 2016: cwhsu points out in the comments the following possible url:

you could just use curl --user USER:PWD http://JENKINS_SERVER/job/JOB_NAME/build?token=YOUR_TOKEN if you set trigger config in your item

June 2016, polaretto points out in the comments:

I wanted to add that with just a little of shell scripting you can avoid manual url configuration, especially if you have many repositories under a common directory.
For example I used these parameter expansions to get the repo name

repository=${PWD%/hooks}; 
repository=${repository##*/} 

and then use it like:

curl $JENKINS_URL/git/notifyCommit?url=$GIT_URL/$repository

Using Linux Instead of regexp take the first line and take out the current resolution values.

Current resolution of display :0

>>> screen = os.popen("xrandr -q -d :0").readlines()[0]
>>> print screen
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 1920 x 1920
>>> width = screen.split()[7]
>>> print width
1920
>>> height = screen.split()[9][:-1]
>>> print height
1080
>>> print "Current resolution is %s x %s" % (width,height)
Current resolution is 1920 x 1080

This was done on xrandr 1.3.5, I don't know if the output is different on other versions, but this should make it easy to figure out.

1. First, make sure that you've committed everything.

2. Then reset your repository to the previous working state:

   $ git reset f836e4c1fa51524658b9f026eb5efa24afaf3a36
   

   or using --hard (this will remove all local, not committed changes!):

   $ git reset f836e4c1fa51524658b9f026eb5efa24afaf3a36 --hard
   

   Use the hash which was there before your wrongly merged commit.

3. Check which commits you'd like to re-commit on the top of the previous correct version by:

   $ git log 4c3e23f529b581c3cbe95350e84e66e3cb05704f
   
   commit 4c3e23f529b581c3cbe95350e84e66e3cb05704f
   
   ...
   
   commit 16b373a96b0a353f7454b141f7aa6f548c979d0a
   
   ...
   

4. Apply your right commits on the top of the right version of your repository by:

   • By using cherry-pick (the changes introduced by some existing commits)

         git cherry-pick ec59ab844cf504e462f011c8cc7e5667ebb2e9c7
     

   • Or by cherry-picking the range of commits by:

     • First checking the right changes before merging them:

       git diff 5216b24822ea1c48069f648449997879bb49c070..4c3e23f529b581c3cbe95350e84e66e3cb05704f
       

     • First checking the right changes before merging them:

       git cherry-pick 5216b24822ea1c48069f648449997879bb49c070..4c3e23f529b581c3cbe95350e84e66e3cb05704f
       

       where this is the range of the correct commits which you've committed (excluding wrongly committed merge).

By pid:

pgrep [pid] >/dev/null

By name:

pgrep -u [user] -x [name] >/dev/null

"-x" means "exact match".

you can use not(expression) function

or

expression != true()

sudo apt-get install build-essential is enough to get it working.

For example:

My file path:

C:\...\sdk\extras\google\usb_driver\android_winusb.inf

My data to paste:

;Tablet PC

%SingleAdbInterface%        = USB_Install, USB\VID_18D1&PID_0003&MI_01

%CompositeADBInterface%     = USB_Install, USB\VID_18D1&PID_0003&REV_0230&MI_01

You say that the matrices are the same dimensions, and yet you are trying to perform matrix multiplication on them. Multiplication of matrices with the same dimension is only possible if they are square. In your case, you get an assertion error, because the dimensions are not square. You have to be careful when multiplying matrices, as there are two possible meanings of multiply.

Matrix multiplication is where two matrices are multiplied directly. This operation multiplies matrix A of size [a x b] with matrix B of size [b x c] to produce matrix C of size [a x c]. In OpenCV it is achieved using the simple * operator:

C = A * B

Element-wise multiplication is where each pixel in the output matrix is formed by multiplying that pixel in matrix A by its corresponding entry in matrix B. The input matrices should be the same size, and the output will be the same size as well. This is achieved using the mul() function:

output = A.mul(B);

Deprecated means they don't recommend using it, and that it isn't undergoing further development. But it should not work differently than it did in a previous version unless documentation explicitly states that.

1. Yes, otherwise it wouldn't be called "deprecated"

2. Unless stated otherwise in docs, it should be the same as before

3. No, but if there were problems in v1 they aren't about to fix them

Perhaps you were looking at the space complexity? That is O(n). The other complexities are as expected on the hash table entry. The search complexity approaches O(1) as the number of buckets increases. If at the worst case you have only one bucket in the hash table, then the search complexity is O(n).

Edit in response to comment I don't think it is correct to say O(1) is the average case. It really is (as the wikipedia page says) O(1+n/k) where K is the hash table size. If K is large enough, then the result is effectively O(1). But suppose K is 10 and N is 100. In that case each bucket will have on average 10 entries, so the search time is definitely not O(1); it is a linear search through up to 10 entries.

The load() function is an asynchronous function. You should set the focus after the load() call finishes, that is in the callback function of load(), because otherwise the element you are referring to by #header, does not yet exist. For example:

$("#display").load("?control=msgs", {}, function() { 
  $('#header').focus();
}); 

I had issues myself even with this solution, so i did a setTimeout in the callback and set the focus in the timeout to make /really/ sure the element exists.

EDIT: as_matrix is deprecated since version 0.23.0

You can use the built in values or to_numpy (recommended option) method on the dataframe:

In [8]:
df.to_numpy()

Out[8]:
array([[  0.9,   7. ,   5.2, ...,  13.3,  13.5,   8.9],
   [  0.9,   7. ,   5.2, ...,  13.3,  13.5,   8.9],
   [  0.8,   6.1,   5.4, ...,  15.9,  14.4,   8.6],
   ..., 
   [  0.2,   1.3,   2.3, ...,  16.1,  16.1,  10.8],
   [  0.2,   1.3,   2.4, ...,  16.5,  15.9,  11.4],
   [  0.2,   1.3,   2.4, ...,  16.5,  15.9,  11.4]])

If you explicitly want lists and not a numpy array add .tolist():

df.to_numpy().tolist()

This is a C++ interview test question not homework.

Then your interviewer needs to refresh his recollection with how the C++ standard works. And I quote:

For an enumeration whose underlying type is not fixed, the underlying type is an integral type that can represent all the enumerator values defined in the enumeration.

The whole "whose underlying type is not fixed" part is from C++11, but the rest is all standard C++98/03. In short, the sizeof(months_t) is not 4. It is not 2 either. It could be any of those. The standard does not say what size it should be; only that it should be big enough to fit any enumerator.

why the all size is 4 bytes ? not 12 x 4 = 48 bytes ?

Because enums are not variables. The members of an enum are not actual variables; they're just a semi-type-safe form of #define. They're a way of storing a number in a reader-friendly format. The compiler will transform all uses of an enumerator into the actual numerical value.

Enumerators are just another way of talking about a number. january is just shorthand for 0. And how much space does 0 take up? It depends on what you store it in.

1. fs.readdir(path, callback)
2. fs.rename(old,new,callback)

Go through http://nodejs.org/api/fs.html

One important thing - you can use sync functions also. (It will work like C program)

this is useful to know about hashcode in java :

http://eclipsesource.com/blogs/2012/09/04/the-3-things-you-should-know-about-hashcode/

You just have to define that Animal implements Comparable<Animal> i.e. public class Animal implements Comparable<Animal>. And then you have to implement the compareTo(Animal other) method that way you like it.

@Override
public int compareTo(Animal other) {
    return Integer.compare(this.year_discovered, other.year_discovered);
}

Using this implementation of compareTo, animals with a higher year_discovered will get ordered higher. I hope you get the idea of Comparable and compareTo with this example.

Theres the ByteArrayInputStream.

It does exactly this.

In c, you could use fopen, and getch. Usually, if you can't be exactly sure of the length of the longest line, you could allocate a large buffer (e.g. 8kb) and almost be guaranteed of getting all lines.

If there's a chance you may have really really long lines and you have to process line by line, you could malloc a resonable buffer, and use realloc to double it's size each time you get close to filling it.

#include <stdio.h>
#include <stdlib.h>

void handle_line(char *line) {
  printf("%s", line);
}

int main(int argc, char *argv[]) {
    int size = 1024, pos;
    int c;
    char *buffer = (char *)malloc(size);

    FILE *f = fopen("myfile.txt", "r");
    if(f) {
      do { // read all lines in file
        pos = 0;
        do{ // read one line
          c = fgetc(f);
          if(c != EOF) buffer[pos++] = (char)c;
          if(pos >= size - 1) { // increase buffer length - leave room for 0
            size *=2;
            buffer = (char*)realloc(buffer, size);
          }
        }while(c != EOF && c != '\n');
        buffer[pos] = 0;
        // line is now in buffer
        handle_line(buffer);
      } while(c != EOF); 
      fclose(f);           
    }
    free(buffer);
    return 0;
}

For Excel 2016 64-bit on a Windows 10 machine, I have used a hex editor to be able to change the password of a protected xla (have not tested this for any other extensions). Tip: create a backup before you do this.

The steps I took:

1. Open the vba in the hex editor (for example XVI)
2. Search on this DPB
3. Change DPB to something else, like DPX
4. Save it!
5. Reopen the .xla, an error message will appear, just continue.
6. You can now change the password of the .xla by opening the properties and go to the password tab.

I hope this helped some of you!

Use this regex (?<!\\)' for searching an unescaped apostrophe. It finds an apostrophe that not preceded by a backslash.

MySQL will assume the part before the equals references the columns named in the INSERT INTO clause, and the second part references the SELECT columns.

INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, 
                inact, inadur, inadist, 
                smlct, smldur, smldist, 
                larct, lardur, lardist, 
                emptyct, emptydur)
SELECT id, uid, t.location, t.animal, t.starttime, t.endtime, t.entct, 
       t.inact, t.inadur, t.inadist, 
       t.smlct, t.smldur, t.smldist, 
       t.larct, t.lardur, t.lardist, 
       t.emptyct, t.emptydur 
FROM tmp t WHERE uid=x
ON DUPLICATE KEY UPDATE entct=t.entct, inact=t.inact, ...

The capitalization is wrong, and you have an extra argument.

Do this instead:

$('img#thumb').removeAttr('id');

For future reference, there aren't any jQuery methods that begin with a capital letter. They all take the same form as this one, starting with a lower case, and the first letter of each joined "word" is upper case.

The real problem is that the variable line always has a value. The test for "no matches found" is whether there is a match so the code "if line == None:" should be replaced with "else:"

firstly I don't think there is just one solution to your problem....

As you know each browser is vastly differant.

But lets see if we can get any closer to the answer you need....

I think IE Might be easy...

Check this link http://support.microsoft.com/kb/181050

For Firefox try this:

Open Firefox, and in the address bar, type "about:config" (without quotes). From there, scroll down to the Network.http.keep-alive and make sure that is set to "true". If it is not, double click it, and it will go from false to true. Now, go one below that to network.http.keep-alive.timeout -- and change that number by double clicking it. if you put in, say, 500 there, you should be good. let us know if this helps at all

dmidecode -t 17 | grep  Size:

Adding all above values displayed after "Size: " will give exact total physical size of all RAM sticks in server.

Here's my improved version of Pointy's solution:

function sortSelectOptions(selector, skip_first) {
    var options = (skip_first) ? $(selector + ' option:not(:first)') : $(selector + ' option');
    var arr = options.map(function(_, o) { return { t: $(o).text(), v: o.value, s: $(o).prop('selected') }; }).get();
    arr.sort(function(o1, o2) {
      var t1 = o1.t.toLowerCase(), t2 = o2.t.toLowerCase();
      return t1 > t2 ? 1 : t1 < t2 ? -1 : 0;
    }); 
    options.each(function(i, o) {
        o.value = arr[i].v;
        $(o).text(arr[i].t);
        if (arr[i].s) {
            $(o).attr('selected', 'selected').prop('selected', true);
        } else {
            $(o).removeAttr('selected');
            $(o).prop('selected', false);
        }
    }); 
}

The function has the skip_first parameter, which is useful when you want to keep the first option on top, e.g. when it's "choose below:".

It also keeps track of the previously selected option.

Example usage:

jQuery(document).ready(function($) {

  sortSelectOptions('#select-id', true);

});

Please note that in upcoming version of C# which is 8, the answers are not true.

All the reference types are non-nullable by default and you can actually do the following:

public string? MyNullableString; 
this.MyNullableString = null; //Valid

However,

public string MyNonNullableString; 
this.MyNonNullableString = null; //Not Valid and you'll receive compiler warning. 

The important thing here is to show the intent of your code. If the "intent" is that the reference type can be null, then mark it so otherwise assigning null value to non-nullable would result in compiler warning.

    android:bottomRightRadius="7dp"
    android:topLeftRadius="7dp"
   android:topRightRadius="7dp" />
</shape>

I've just created a little example showing how to implement commands in convention over configuration style. However it requires Reflection.Emit() to be available. The supporting code may seem a little weird but once written it can be used many times.

Teaser:

public class SampleViewModel: BaseViewModelStub
{
    public string Name { get; set; }

    [UiCommand]
    public void HelloWorld()
    {
        MessageBox.Show("Hello World!");
    }

    [UiCommand]
    public void Print()
    {
        MessageBox.Show(String.Concat("Hello, ", Name, "!"), "SampleViewModel");
    }

    public bool CanPrint()
    {
        return !String.IsNullOrEmpty(Name);
    }
}

}

UPDATE: now there seem to exist some libraries like http://www.codeproject.com/Articles/101881/Executing-Command-Logic-in-a-View-Model that solve the problem of ICommand boilerplate code.

You can do: $date = \gmdate(\DATE_ISO8601);.

For those experiencing this error on CI/CD, adding the line below worked for me on my GitHub Actions CI/CD workflow right after running pip install pyflakes diff-cover:

git fetch origin master:refs/remotes/origin/master

This is a snippet of the solution from the diff-cover github repo:

Solution: diff-cover matches source files in the coverage XML report with source files in the git diff. For this reason, it's important that the relative paths to the files match. If you are using coverage.py to generate the coverage XML report, then make sure you run diff-cover from the same working directory.

I got the solution on the links below. It is a documented diff-cover error.

https://diff-cover.readthedocs.io/en/latest//README.html https://github.com/Bachmann1234/diff_cover/blob/master/README.rst

Hope this helps :-).

Update for C++11

As of the C++11 standard, string-to-number conversion and vice-versa are built in into the standard library. All the following functions are present in <string> (as per paragraph 21.5).

string to numeric

float              stof(const string& str, size_t *idx = 0);
double             stod(const string& str, size_t *idx = 0);
long double        stold(const string& str, size_t *idx = 0);
int                stoi(const string& str, size_t *idx = 0, int base = 10);
long               stol(const string& str, size_t *idx = 0, int base = 10);
unsigned long      stoul(const string& str, size_t *idx = 0, int base = 10);
long long          stoll(const string& str, size_t *idx = 0, int base = 10);
unsigned long long stoull(const string& str, size_t *idx = 0, int base = 10);

Each of these take a string as input and will try to convert it to a number. If no valid number could be constructed, for example because there is no numeric data or the number is out-of-range for the type, an exception is thrown (std::invalid_argument or std::out_of_range).

If conversion succeeded and idx is not 0, idx will contain the index of the first character that was not used for decoding. This could be an index behind the last character.

Finally, the integral types allow to specify a base, for digits larger than 9, the alphabet is assumed (a=10 until z=35). You can find more information about the exact formatting that can parsed here for floating-point numbers, signed integers and unsigned integers.

Finally, for each function there is also an overload that accepts a std::wstring as it's first parameter.

numeric to string

string to_string(int val);
string to_string(unsigned val);
string to_string(long val);
string to_string(unsigned long val);
string to_string(long long val);
string to_string(unsigned long long val);
string to_string(float val);
string to_string(double val);
string to_string(long double val);

These are more straightforward, you pass the appropriate numeric type and you get a string back. For formatting options you should go back to the C++03 stringsream option and use stream manipulators, as explained in an other answer here.

As noted in the comments these functions fall back to a default mantissa precision that is likely not the maximum precision. If more precision is required for your application it's also best to go back to other string formatting procedures.

There are also similar functions defined that are named to_wstring, these will return a std::wstring.

Here is an example of accessing the ith index of a std::vector using an std::iterator within a loop which does not require incrementing two iterators.

std::vector<std::string> strs = {"sigma" "alpha", "beta", "rho", "nova"};
int nth = 2;
std::vector<std::string>::iterator it;
for(it = strs.begin(); it != strs.end(); it++) {
    int ith = it - strs.begin();
    if(ith == nth) {
        printf("Iterator within  a for-loop: strs[%d] = %s\n", ith, (*it).c_str());
    }
}

Without a for-loop

it = strs.begin() + nth;
printf("Iterator without a for-loop: strs[%d] = %s\n", nth, (*it).c_str());

and using at method:

printf("Using at position: strs[%d] = %s\n", nth, strs.at(nth).c_str());

see RFC6265:

The user agent will reject cookies unless the Domain attribute specifies a scope for the cookie that would include the origin server. For example, the user agent will accept a cookie with a Domain attribute of "example.com" or of "foo.example.com" from foo.example.com, but the user agent will not accept a cookie with a Domain attribute of "bar.example.com" or of "baz.foo.example.com".

NOTE: For security reasons, many user agents are configured to reject Domain attributes that correspond to "public suffixes". For example, some user agents will reject Domain attributes of "com" or "co.uk". (See Section 5.3 for more information.)

But the above mentioned workaround with image/iframe works, though it's not recommended due to its insecurity.

With a BorderLayout you need to use setPreferredSize instead of setSize

You can just simply add the following code;

<a class="btn btn-primary" href="http://localhost:8080/Home" role="button">Home Page</a>

Yes.

<?  if($my_name == 'someguy') { ?>
        HTML_GOES_HERE
<?  } ?>

With jQuery 1.6 version you can use the .promise() method.

$(selector).fadeOut('slow');
$(selector).promise().done(function(){
    // will be called when all the animations on the queue finish
});

I encountered the same problem. What caused it for me were a bunch of whitespaces ( ) that I inserted. After removing them, the problem was solved.

You want to apply a custom formatting rule. The "Applies to" field should be your entire row (If you want to format row 5, put in =$5:$5. The custom formula should be =IF($B$5="X", TRUE, FALSE), shown in the example below.

When you cherry-pick, it creates a new commit with a new SHA. If you do:

git cherry-pick -x <sha>

then at least you'll get the commit message from the original commit appended to your new commit, along with the original SHA, which is very useful for tracking cherry-picks.

Question is a little vague.

list_of_lines = multiple_lines.split("\n")
for line in list_of_lines:
    list_of_items_in_line = line.split(",")
    first_int = int(list_of_items_in_line[0])

etc.

It's called String#start_with?, not String#startswith: In Ruby, the names of boolean-ish methods end with ? and the words in method names are separated with an _. Not sure where the s went, personally, I'd prefer String#starts_with? over the actual String#start_with?

This workflow works best for me:

git checkout -b develop

After reading the accepted answer's comments, I tried the robocopy command, which worked for me (using the standard command prompt from Windows 7 64 bits SP 1):

robocopy source_dir dest_dir /s /e

Create a 3D matrix

A = zeros(20, 10, 3);   %# Creates a 20x10x3 matrix

Add a 3rd dimension to a matrix

B = zeros(4,4);  
C = zeros(size(B,1), size(B,2), 4);  %# New matrix with B's size, and 3rd dimension of size 4
C(:,:,1) = B;                        %# Copy the content of B into C's first set of values

zeros is just one way of making a new matrix. Another could be A(1:20,1:10,1:3) = 0 for a 3D matrix. To confirm the size of your matrices you can run: size(A) which gives 20 10 3.

There is no explicit bound on the number of dimensions a matrix may have.

2017 update

$lookup can now directly use an array as the local field. $unwind is no longer needed.

Old answer

The $lookup aggregation pipeline stage will not work directly with an array. The main intent of the design is for a "left join" as a "one to many" type of join ( or really a "lookup" ) on the possible related data. But the value is intended to be singular and not an array.

Therefore you must "de-normalise" the content first prior to performing the $lookup operation in order for this to work. And that means using $unwind:

db.orders.aggregate([
    // Unwind the source
    { "$unwind": "$products" },
    // Do the lookup matching
    { "$lookup": {
       "from": "products",
       "localField": "products",
       "foreignField": "_id",
       "as": "productObjects"
    }},
    // Unwind the result arrays ( likely one or none )
    { "$unwind": "$productObjects" },
    // Group back to arrays
    { "$group": {
        "_id": "$_id",
        "products": { "$push": "$products" },
        "productObjects": { "$push": "$productObjects" }
    }}
])

After $lookup matches each array member the result is an array itself, so you $unwind again and $group to $push new arrays for the final result.

Note that any "left join" matches that are not found will create an empty array for the "productObjects" on the given product and thus negate the document for the "product" element when the second $unwind is called.

Though a direct application to an array would be nice, it's just how this currently works by matching a singular value to a possible many.

As $lookup is basically very new, it currently works as would be familiar to those who are familiar with mongoose as a "poor mans version" of the .populate() method offered there. The difference being that $lookup offers "server side" processing of the "join" as opposed to on the client and that some of the "maturity" in $lookup is currently lacking from what .populate() offers ( such as interpolating the lookup directly on an array ).

This is actually an assigned issue for improvement SERVER-22881, so with some luck this would hit the next release or one soon after.

As a design principle, your current structure is neither good or bad, but just subject to overheads when creating any "join". As such, the basic standing principle of MongoDB in inception applies, where if you "can" live with the data "pre-joined" in the one collection, then it is best to do so.

The one other thing that can be said of $lookup as a general principle, is that the intent of the "join" here is to work the other way around than shown here. So rather than keeping the "related ids" of the other documents within the "parent" document, the general principle that works best is where the "related documents" contain a reference to the "parent".

So $lookup can be said to "work best" with a "relation design" that is the reverse of how something like mongoose .populate() performs it's client side joins. By idendifying the "one" within each "many" instead, then you just pull in the related items without needing to $unwind the array first.

Actually, you do not need to do a first guess. Simply doing

import matplotlib.pyplot as plt  
from scipy.optimize import curve_fit
from scipy import asarray as ar,exp

x = ar(range(10))
y = ar([0,1,2,3,4,5,4,3,2,1])

n = len(x)                          #the number of data
mean = sum(x*y)/n                   #note this correction
sigma = sum(y*(x-mean)**2)/n        #note this correction

def gaus(x,a,x0,sigma):
    return a*exp(-(x-x0)**2/(2*sigma**2))

popt,pcov = curve_fit(gaus,x,y)
#popt,pcov = curve_fit(gaus,x,y,p0=[1,mean,sigma])

plt.plot(x,y,'b+:',label='data')
plt.plot(x,gaus(x,*popt),'ro:',label='fit')
plt.legend()
plt.title('Fig. 3 - Fit for Time Constant')
plt.xlabel('Time (s)')
plt.ylabel('Voltage (V)')
plt.show()

works fine. This is simpler because making a guess is not trivial. I had more complex data and did not manage to do a proper first guess, but simply removing the first guess worked fine :)

P.S.: use numpy.exp() better, says a warning of scipy

This specifies the default collation for the database. Every text field that you create in tables in the database will use that collation, unless you specify a different one.

A database always has a default collation. If you don't specify any, the default collation of the SQL Server instance is used.

The name of the collation that you use shows that it uses the Latin1 code page 1, is case insensitive (CI) and accent sensitive (AS). This collation is used in the USA, so it will contain sorting rules that are used in the USA.

The collation decides how text values are compared for equality and likeness, and how they are compared when sorting. The code page is used when storing non-unicode data, e.g. varchar fields.

Xamarin Forms Android:

//---------------------------------------------------------
{
    var intent = new Intent(Android.Provider.Settings.ActionApplicationDetailsSettings,
        Android.Net.Uri.Parse("package:" + Forms.Context.PackageName));
    Forms.Context.StartActivity(intent);
}

Use the instanceof operator:

if(a instanceof MyClass)

    //do something
}

I assume you know what a byte is. A byte array is simply an area of memory containing a group of contiguous (side by side) bytes, such that it makes sense to talk about them in order: the first byte, the second byte etc..

Just as bytes can encode different types and ranges of data (numbers from 0 to 255, numbers from -128 to 127, single characters using ASCII e.g. 'a' or '%', CPU op-codes), each byte in a byte array may be any of these things, or contribute to some multi-byte values such as numbers with larger range (e.g. 16-bit unsigned int from 0..65535), international character sets, textual strings ("hello"), or part/all of a compiled computer programs.

The crucial thing about a byte array is that it gives indexed (fast), precise, raw access to each 8-bit value being stored in that part of memory, and you can operate on those bytes to control every single bit. The bad thing is the computer just treats every entry as an independent 8-bit number - which may be what your program is dealing with, or you may prefer some powerful data-type such as a string that keeps track of its own length and grows as necessary, or a floating point number that lets you store say 3.14 without thinking about the bit-wise representation. As a data type, it is inefficient to insert or remove data near the start of a long array, as all the subsequent elements need to be shuffled to make or fill the gap created/required.

Coloured, word-level diff ouput

Here's what you can do with the the below script and diff-highlight:

#!/bin/sh -eu

# Use diff-highlight to show word-level differences

diff -U3 --minimal "$@" |
  sed 's/^-/\x1b[1;31m-/;s/^+/\x1b[1;32m+/;s/^@/\x1b[1;34m@/;s/$/\x1b[0m/' |
  diff-highlight

_{(Credit to @retracile's answer for the sed highlighting)}

I'm late to the party here, but if you're dealing with integers of a fixed length you can just do integer comparison:

SELECT * FROM books WHERE price > 89999 AND price < 90100;

Use this script

 <script type="text/javascript">
      window.onload = function() { window.print(); }
 </script>

How about this

$.validate.addMethod(cb_selectone,
                   function(value,element){
                           if(element.length>0){
                               for(var i=0;i<element.length;i++){
                                if($(element[i]).val('checked')) return true;
                               }
                           return false;
                           }
                            return false;
                  },
                  'Please select a least one')

Now you ca do

$.validate({rules:{checklist:"cb_selectone"}});

You can even go further a specify the minimum number to select with a third param in the callback function.I have not tested it yet so tell me if it works.

Disabling the Sync to VBlank checkbox in nvidia-settings (OpenGL Settings tab) does the trick for me.

Two conditions can be used to check if the page is loaded before finding any element on the page:

WebDriverWait wait = new WebDriverWait(driver, 50);

Using below readyState will wait till page load

wait.until((ExpectedCondition<Boolean>) wd ->
   ((JavascriptExecutor) wd).executeScript("return document.readyState").equals("complete"));

Below JQuery will wait till data has not been loaded

  int count =0;
            if((Boolean) executor.executeScript("return window.jQuery != undefined")){
                while(!(Boolean) executor.executeScript("return jQuery.active == 0")){
                    Thread.sleep(4000);
                    if(count>4)
                        break;
                    count++;
                }
            }

After these JavaScriptCode try to findOut webElement.

WebElement we = wait.until(ExpectedConditions.presenceOfElementLocated(by));

In my case, there is 14 input edit text in the list view. The problem I was facing, when the keyboard open, edit text focus lost, scroll the layout, and as soon as focused view not visible to the user keyboard down. It was not good for the user experience. I can't use windowSoftInputMethod="adjustPan". So after so much searching, I found a link that inflates custom layout and sets data on view as an adapter by using LinearLayout and scrollView and work well for my case.

Java Beans are not the same thing as EJBs.

The JavaBeans specification in Java 1.0 was Sun's attempt to allow Java objects to be manipulated in an IDE that looked like VB. There were rules laid down for objects that qualified as "Java Beans":

1. Default constructor
2. Getters and setters for private data members that followed the proper naming convention
3. Serializable
4. Maybe others that I'm forgetting.

EJBs came later. They combine distributed components and a transactional model, running in a container that manages threads, pooling, life cycle, and provides services. They are a far cry from Java Beans.

DTOs came about in the Java context because people found out that the EJB 1.0 spec was too "chatty" with the database. Rather than make a roundtrip for every data element, people would package them into Java Beans in bulk and ship them around.

POJOs were a reaction against EJBs.

If you really want to get the type by name you may use the following:

System.AppDomain.CurrentDomain.GetAssemblies().SelectMany(x => x.GetTypes()).First(x => x.Name == "theassembly");

Note that you can improve the performance of this drastically the more information you have about the type you're trying to load.

ToggleButton inherits from TextView so you can set drawables to be displayed at the 4 borders of the text. You can use that to display the icon you want on top of the text and hide the actual text

<ToggleButton
    android:id="@+id/toggleButton1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:drawableTop="@android:drawable/ic_menu_info_details"
    android:gravity="center"
    android:textOff=""
    android:textOn=""
    android:textSize="0dp" />

The result compared to regular ToggleButton looks like

The seconds option is to use an ImageSpan to actually replace the text with an image. Looks slightly better since the icon is at the correct position but can't be done with layout xml directly.

You create a plain ToggleButton

<ToggleButton
    android:id="@+id/toggleButton3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="false" />

Then set the "text" programmatially

ToggleButton button = (ToggleButton) findViewById(R.id.toggleButton3);
ImageSpan imageSpan = new ImageSpan(this, android.R.drawable.ic_menu_info_details);
SpannableString content = new SpannableString("X");
content.setSpan(imageSpan, 0, 1, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
button.setText(content);
button.setTextOn(content);
button.setTextOff(content);

The result here in the middle - icon is placed slightly lower since it takes the place of the text.

<form id = "uploadForm" name = "uploadForm" enctype="multipart/form-data">
    <label for="uploadFile">Upload Your File</label>
     <input type="file" name="uploadFile" id="uploadFile">                  
</form>
<script>
    $('#uploadFile').change(function(){
        var fileName = this.files[0].name;
        var fileSize = this.files[0].size;
        var fileType = this.files[0].type;
        alert('FileName : ' + fileName + '\nFileSize : ' + fileSize + ' bytes');
    });
</script>

Note: To get the uploading file name means then use jquery val() method.

For Ex:

var fileName = $('#uploadFile').val();

I checked this above code before post, it works perfectly.!

It is simple actually, like C programming you just need to pass the array indices on the right hand side while declaration. But yeah the syntax will be like [0:3] for 4 elements.

reg a[0:3]; 

This will create a 1D of array of single bit. Similarly 2D array can be created like this:

reg [0:3][0:2];

Now in C suppose you create a 2D array of int, then it will internally create a 2D array of 32 bits. But unfortunately Verilog is an HDL, so it thinks in bits rather then bunch of bits (though int datatype is there in Verilog), it can allow you to create any number of bits to be stored inside an element of array (which is not the case with C, you can't store 5-bits in every element of 2D array in C). So to create a 2D array, in which every individual element can hold 5 bit value, you should write this:

reg [0:4] a [0:3][0:2];

Can you post your code? I'm not finding any issue with this. Tested on Firefox 3.01/safari 3.1.2 with:

function showMe(e) {
// i am spammy!
  alert(e.value);
}
....
<input type="text" id="foo" value="bar" onkeyup="showMe(this)" />

Use the css "rotate()" method:

div {
  width: 100px;
  height: 100px;
  background-color: yellow;
  border: 1px solid black;
}

div#rotate{
  transform: rotate(90deg);
}

<div>
normal div
</div>
<br>

<div id="rotate">
This div is rotated 90 degrees
</div>

try use this code it works for me. by the way it came from this site https://github.com/eternicode/bootstrap-datepicker/issues/464 .

$('#datepicker').datepicker().on('show', function () {
                var modal = $('#datepicker').closest('.modal');
                var datePicker = $('body').find('.datepicker');
                if (!modal.length) {
                    $(datePicker).css('z-index', 'auto');
                    return;
                }
                var zIndexModal = $(modal).css('z-index');
                $(datePicker).css('z-index', zIndexModal + 1);
            });

HttpClient is not supported in sdk 23 and 23+.

If you need to use into sdk 23, add below code to your gradle:

android {
    useLibrary 'org.apache.http.legacy'
}

Its working for me. Hope useful for you.

Thanks to both of you. At some point I had to give up on trying to detect if the mouse was still over the element. I know it's possible, but may require too much code to accomplish.

It took me a little while but I took both of your suggestions and came up with something that would work for me.

Here's a simplified (but functional) example:

$("[HoverHelp]").hover (
    function () {
        var HelpID = "#" + $(this).attr("HoverHelp");
        $(HelpID).css("top", $(this).position().top + 25);
        $(HelpID).css("left", $(this).position().left);
        $(HelpID).attr("fadeout", "false");
        $(HelpID).fadeIn();
    },
    function () {
        var HelpID = "#" + $(this).attr("HoverHelp");
        $(HelpID).attr("fadeout", "true");
        setTimeout(function() { if ($(HelpID).attr("fadeout") == "true") $(HelpID).fadeOut(); }, 100);
    }
);

And then to make this work on some text this is all I have to do:

<div id="tip_TextHelp" style="display: none;">This help text will show up on a mouseover, and fade away 100 milliseconds after a mouseout.</div>

This is a <span class="Help" HoverHelp="tip_TextHelp">mouse over</span> effect.

Along with a lot of fancy CSS, this allows some very nice mouseover help tooltips. By the way, I needed the delay in the mouseout because of tiny gaps between checkboxes and text that was causing the help to flash as you move the mouse across. But this works like a charm. I also did something similar for the focus/blur events.

Please be aware, this is a simplified explanation intended as a first step in seeking to understand this complex functionality.

May be helpful for visual learners who want to visualise what their project state looks like after each of these commands:

Given: - A - B - C (master)

For those who use Terminal with colour turned on (git config --global color.ui auto):

git reset --soft A and you will see B and C's stuff in green (staged and ready to commit)

git reset --mixed A (or git reset A) and you will see B and C's stuff in red (unstaged and ready to be staged (green) and then committed)

git reset --hard A and you will no longer see B and C's changes anywhere (will be as if they never existed)

Or for those who use a GUI program like 'Tower' or 'SourceTree'

git reset --soft A and you will see B and C's stuff in the 'staged files' area ready to commit

git reset --mixed A (or git reset A) and you will see B and C's stuff in the 'unstaged files' area ready to be moved to staged and then committed

git reset --hard A and you will no longer see B and C's changes anywhere (will be as if they never existed)

If it is as your example of adding " World" to the original string, then it can be:

#!/bin/bash

foo="Hello"
foo=$foo" World"
echo $foo

The output:

Hello World
