This solution may help you if you know your problem is limited to Facades and you are running Laravel 5.5 or above.

Install laravel-ide-helper

composer require --dev barryvdh/laravel-ide-helper

Add this conditional statement in your AppServiceProvider to register the helper class.

public function register()
{
    if ($this->app->environment() !== 'production') {
        $this->app->register(\Barryvdh\LaravelIdeHelper\IdeHelperServiceProvider::class);
    }
    // ...
}

Then run php artisan ide-helper:generate to generate a file to help the IDE understand Facades. You will need to restart Visual Studio Code.

When you adding assets directory in pubspec.yaml file give more attention in to spaces

this is wrong

flutter:
   assets:
    - assets/images/lake.jpg

This is the correct way,

flutter:
  assets:
    - assets/images/

If using Visual Code one option is to add this to the settings.json file:

"eslint.options": {
    "useEslintrc": false,
    "parserOptions": {
        "ecmaVersion": 2017
    },
    "env": {
        "es6": true
    }
}

please make sure following changes should be uncommented, which I did and got succeed in centos7

vi /etc/ssh/sshd_config

1.PubkeyAuthentication yes

2.PasswordAuthentication yes

3.GSSAPIKeyExchange no

4.GSSAPICleanupCredentials no

systemctl restart sshd

ssh-keygen

chmod 777 /root/.ssh/id_rsa.pub 

ssh-copy-id -i /root/.ssh/id_rsa.pub user@ipaddress

thank you all and good luck

This would work as well:

df = pd.DataFrame()
new_line = pd.Series({'A2M': 4.059, 'A2ML1': 4.28}, name='HCC1419')
df = df.append(new_line, ignore_index=False)

The name in the Series will be the index in the dataframe. ignore_index=False is the important flag in this case.

I saw it's solved, but I still want to share a solution which worked for me.

.env file:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=[your database name]
DB_USERNAME=[your MySQL username]
DB_PASSWORD=[your MySQL password]

MySQL admin:

 SELECT user, host FROM mysql.user

Thank you, spencer7593

Console:

php artisan cache:clear
php artisan config:cache

Now it works for me.

Laracasts answers

Just a small observation: you keep mentioning conn usr\pass, and this is a typo, right? Cos it should be conn usr/pass. Or is it different on a Unix based OS?

Furthermore, just to be sure: if you use tnsnames, your login string will look different from when you use the login method you started this topic out with.

tnsnames.ora should be in $ORACLE_HOME$\network\admin. That is the Oracle home on the machine from which you are trying to connect, so in your case your PC. If you have multiple oracle_homes and wish to use only one tnsnames.ora, you can set environment variable tns_admin (e.g. set TNS_ADMIN=c:\oracle\tns), and place tnsnames.ora in that directory.

Your original method of logging on (usr/[email protected]:port/servicename) should always work. So far I think you have all the info, except for the port number, which I am sure your DBA will be able to give you. If this method still doesn't work, either the server's IP address is not available from your client, or it is a firewall issue (blocking a certain port), or something else not (directly) related to Oracle or SQL*Plus.

@media (max-width: 767px) {
    footer .text-right, 
    footer .text-left {
        text-align: center;
    } 
}

I updated @loddn's answer, making two changes

• max-width of xs screens in bootstrap is 767px (768px is the start of sm screens)
• (this one is a matter of preference) I used footer instead of col-* so that if the column widths change, the CSS doesn't need to be updated.

You can use the following command to update the DATA PUMP DIRECTORY path,

create or replace directory DATA_PUMP_DIR as '/u01/app/oracle/admin/MYDB/dpdump/';

For me data path correction was required as I have restored the my database from production to test environment.

Same command can be used to create a new DATA PUMP DIRECTORY name and path.

For Ubuntu users

If you are getting PANIC: Missing emulator engine program for 'x86' CPU. this error

Try starting your emulator from the emulator folder in SDK, like above

usama@usama-Aspire-V5-471:~/Android/Sdk/emulator$ ./emulator -avd Pixel_2_API_29

Problem

The listener service is stopped in services.msc.

Cause

User password was changed.

Solution

• Open services.msc.
• Right-click the specific listener service.
• Click Properties.
• Click the Logon tab.
• Change the password.
• Click OK.
• Start the service.

These errors mean that the R code you are trying to run or source is not syntactically correct. That is, you have a typo.

To fix the problem, read the error message carefully. The code provided in the error message shows where R thinks that the problem is. Find that line in your original code, and look for the typo.

Prophylactic measures to prevent you getting the error again

The best way to avoid syntactic errors is to write stylish code. That way, when you mistype things, the problem will be easier to spot. There are many R style guides linked from the SO R tag info page. You can also use the formatR package to automatically format your code into something more readable. In RStudio, the keyboard shortcut CTRL + SHIFT + A will reformat your code.

Consider using an IDE or text editor that highlights matching parentheses and braces, and shows strings and numbers in different colours.

Common syntactic mistakes that generate these errors

Mismatched parentheses, braces or brackets

If you have nested parentheses, braces or brackets it is very easy to close them one too many or too few times.

{}}
## Error: unexpected '}' in "{}}"
{{}} # OK

Missing * when doing multiplication

This is a common mistake by mathematicians.

5x
Error: unexpected symbol in "5x"
5*x # OK

Not wrapping if, for, or return values in parentheses

This is a common mistake by MATLAB users. In R, if, for, return, etc., are functions, so you need to wrap their contents in parentheses.

if x > 0 {}
## Error: unexpected symbol in "if x"
if(x > 0) {} # OK

Not using multiple lines for code

Trying to write multiple expressions on a single line, without separating them by semicolons causes R to fail, as well as making your code harder to read.

x + 2 y * 3
## Error: unexpected symbol in "x + 2 y"
x + 2; y * 3 # OK

else starting on a new line

In an if-else statement, the keyword else must appear on the same line as the end of the if block.

if(TRUE) 1
else 2
## Error: unexpected 'else' in "else"    
if(TRUE) 1 else 2 # OK
if(TRUE) 
{
  1
} else            # also OK
{
  2
}

= instead of ==

= is used for assignment and giving values to function arguments. == tests two values for equality.

if(x = 0) {}
## Error: unexpected '=' in "if(x ="    
if(x == 0) {} # OK

Missing commas between arguments

When calling a function, each argument must be separated by a comma.

c(1 2)
## Error: unexpected numeric constant in "c(1 2"
c(1, 2) # OK

Not quoting file paths

File paths are just strings. They need to be wrapped in double or single quotes.

path.expand(~)
## Error: unexpected ')' in "path.expand(~)"
path.expand("~") # OK

Quotes inside strings

This is a common problem when trying to pass quoted values to the shell via system, or creating quoted xPath or sql queries.

Double quotes inside a double quoted string need to be escaped. Likewise, single quotes inside a single quoted string need to be escaped. Alternatively, you can use single quotes inside a double quoted string without escaping, and vice versa.

"x"y"
## Error: unexpected symbol in ""x"y"   
"x\"y" # OK
'x"y'  # OK  

Using curly quotes

So-called "smart" quotes are not so smart for R programming.

path.expand(“~”)
## Error: unexpected input in "path.expand(“"    
path.expand("~") # OK

Using non-standard variable names without backquotes

?make.names describes what constitutes a valid variable name. If you create a non-valid variable name (using assign, perhaps), then you need to access it with backquotes,

assign("x y", 0)
x y
## Error: unexpected symbol in "x y"
`x y` # OK

This also applies to column names in data frames created with check.names = FALSE.

dfr <- data.frame("x y" = 1:5, check.names = FALSE)
dfr$x y
## Error: unexpected symbol in "dfr$x y"
dfr[,"x y"] # OK
dfr$`x y`   # also OK

It also applies when passing operators and other special values to functions. For example, looking up help on %in%.

?%in%
## Error: unexpected SPECIAL in "?%in%"
?`%in%` # OK

Sourcing non-R code

The source function runs R code from a file. It will break if you try to use it to read in your data. Probably you want read.table.

source(textConnection("x y"))
## Error in source(textConnection("x y")) : 
##   textConnection("x y"):1:3: unexpected symbol
## 1: x y
##       ^

Corrupted RStudio desktop file

RStudio users have reported erroneous source errors due to a corrupted .rstudio-desktop file. These reports only occurred around March 2014, so it is possibly an issue with a specific version of the IDE. RStudio can be reset using the instructions on the support page.

Using expression without paste in mathematical plot annotations

When trying to create mathematical labels or titles in plots, the expression created must be a syntactically valid mathematical expression as described on the ?plotmath page. Otherwise the contents should be contained inside a call to paste.

plot(rnorm(10), ylab = expression(alpha ^ *)))
## Error: unexpected '*' in "plot(rnorm(10), ylab = expression(alpha ^ *"
plot(rnorm(10), ylab = expression(paste(alpha ^ phantom(0), "*"))) # OK

for listener support no services you can use the following command to set local_listener paramter in your spfile use your listener port and server ip address

alter system set local_listener='(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.101)(PORT=1520)))' sid='testdb' scope=spfile;

According to Github API two empty lines are a new paragraph (same as here in stackoverflow)

You can test it with http://prose.io

justify-content only has an effect if there's space left over after your flex items have flexed to absorb the free space. In most/many cases, there won't be any free space left, and indeed justify-content will do nothing.

Some examples where it would have an effect:

• if your flex items are all inflexible (flex: none or flex: 0 0 auto), and smaller than the container.

• if your flex items are flexible, BUT can't grow to absorb all the free space, due to a max-width on each of the flexible items.

In both of those cases, justify-content would be in charge of distributing the excess space.

In your example, though, you have flex items that have flex: 1 or flex: 6 with no max-width limitation. Your flexible items will grow to absorb all of the free space, and there will be no space left for justify-content to do anything with.

I came hear looking for this answer but also wanted to pipe it to another command. The given answer is correct but if anyone wants to pipe it, you need to pipe it before the multi-line string like this

echo | tee /tmp/pipetest << EndOfMessage
This is line 1.
This is line 2.
Line 3.
EndOfMessage

This will allow you to have a multi line string but also put it in the stdin of a subsequent command.

The Problem

In MySQL, certain words like SELECT, INSERT, DELETE etc. are reserved words. Since they have a special meaning, MySQL treats it as a syntax error whenever you use them as a table name, column name, or other kind of identifier - unless you surround the identifier with backticks.

As noted in the official docs, in section 10.2 Schema Object Names (emphasis added):

Certain objects within MySQL, including database, table, index, column, alias, view, stored procedure, partition, tablespace, and other object names are known as identifiers.

...

If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it.

...

The identifier quote character is the backtick ("`"):

A complete list of keywords and reserved words can be found in section 10.3 Keywords and Reserved Words. In that page, words followed by "(R)" are reserved words. Some reserved words are listed below, including many that tend to cause this issue.

• ADD
• AND
• BEFORE
• BY
• CALL
• CASE
• CONDITION
• DELETE
• DESC
• DESCRIBE
• FROM
• GROUP
• IN
• INDEX
• INSERT
• INTERVAL
• IS
• KEY
• LIKE
• LIMIT
• LONG
• MATCH
• NOT
• OPTION
• OR
• ORDER
• PARTITION
• RANK
• REFERENCES
• SELECT
• TABLE
• TO
• UPDATE
• WHERE

The Solution

You have two options.

1. Don't use reserved words as identifiers

The simplest solution is simply to avoid using reserved words as identifiers. You can probably find another reasonable name for your column that is not a reserved word.

Doing this has a couple of advantages:

• It eliminates the possibility that you or another developer using your database will accidentally write a syntax error due to forgetting - or not knowing - that a particular identifier is a reserved word. There are many reserved words in MySQL and most developers are unlikely to know all of them. By not using these words in the first place, you avoid leaving traps for yourself or future developers.

• The means of quoting identifiers differs between SQL dialects. While MySQL uses backticks for quoting identifiers by default, ANSI-compliant SQL (and indeed MySQL in ANSI SQL mode, as noted here) uses double quotes for quoting identifiers. As such, queries that quote identifiers with backticks are less easily portable to other SQL dialects.

Purely for the sake of reducing the risk of future mistakes, this is usually a wiser course of action than backtick-quoting the identifier.

2. Use backticks

If renaming the table or column isn't possible, wrap the offending identifier in backticks (`) as described in the earlier quote from 10.2 Schema Object Names.

An example to demonstrate the usage (taken from 10.3 Keywords and Reserved Words):

mysql> CREATE TABLE interval (begin INT, end INT);
ERROR 1064 (42000): You have an error in your SQL syntax.
near 'interval (begin INT, end INT)'
mysql> CREATE TABLE `interval` (begin INT, end INT);
Query OK, 0 rows affected (0.01 sec)

Similarly, the query from the question can be fixed by wrapping the keyword key in backticks, as shown below:

INSERT INTO user_details (username, location, `key`)
VALUES ('Tim', 'Florida', 42)";               ^   ^

Simply set Apache to listen on a different port. This can be done by clicking on the "Config" button on the same line as the "Apache" module, select the "httpd.conf" file in the dropdown, then change the "Listen 80" line to "Listen 8080". Save the file and close it.

Now it avoids Port 80 and uses Port 8080 instead without issue. The only additional thing you need to do is make sure to put localhost:8080 in the browser so the browser knows to look on Port 8080. Otherwise it defaults to Port 80 and won't find your local site.

For ubuntu users, this error may arise because setuptool is not installed system-wide. Simply install setuptool using the command:

sudo apt-get install -y python-setuptools

For python3:

sudo apt-get install -y python3-setuptools

After that, install your package again normally, using

sudo python setup.py install

That's all.

Setup JavaScript Environment

1. Install Node.js

Download installer at NodeJs website. You can download the latest V6

2. Update Npm

Npm is installed together with Node.js. So don't worry.

3. Install Anaconda

Anaconda is the leading open data science platform powered by Python. The open source version of Anaconda is a high performance distribution of Python. It can help you to manage your python dependency. You can use it to create different python environment in the futher if you want to touch with it.

Node-gyp only support >= Python 2.7 and < Python 3.0

So just install the 2.7 version

4. Install Node-gyp

You can install with npm:

$ npm install -g node-gyp

You will also need to install:

• On Windows:

  • Option 1: Install all the required tools and configurations using Microsoft's windows-build-tools using npm install --global --production windows-build-tools from an elevated PowerShell or CMD.exe (run as Administrator).

  • Option 2: Install tools and configuration manually:

  • Visual C++ Build Environment:

    • Option 1: Install Visual C++ Build Tools using the Default Install option.
    • Option 2: Install Visual Studio 2015 (or modify an existing installation) and select Common Tools for Visual C++ during setup. This also works with the free Community and Express for Desktop editions.

     [Windows Vista / 7 only] requires .NET Framework 4.5.1

  • Launch cmd, npm config set msvs_version 2015

  If the above steps didn't work for you, please visit Microsoft's Node.js Guidelines for Windows for additional tips.

If you have multiple Python versions installed, you can identify which Python version node-gyp uses by setting the '--python' variable:

$ node-gyp --python C:/Anaconda2/python.exe

If node-gyp is called by way of npm and you have multiple versions of Python installed, then you can set npm's 'python' config key to the appropriate value:

$ npm config set python C:/Anaconda2/python.exe

Future update for Node.js and npm

Download installer from their official website and direct install it. The installer will automatic help you to remove old files.

npm update npm

Future update for Python

conda update --all

Total memory in Mb:

x=$(awk '/MemTotal/ {print $2}' /proc/meminfo)
echo $((x/1024))

or:

x=$(awk '/MemTotal/ {print $2}' /proc/meminfo) ; echo $((x/1024))

Use Map<Integer, List<String>>:

Map<Integer, List<String>> map = new LinkedHashMap< Integer, List<String>>();

map.put(-1505711364, new ArrayList<>(Arrays.asList("4")));
map.put(294357273, new ArrayList<>(Arrays.asList("15", "71")));
//...

To add a new key/value pair in this map:

public void add(Integer key, String newValue) {
    List<String> currentValue = map.get(key);
    if (currentValue == null) {
        currentValue = new ArrayList<String>();
        map.put(key, currentValue);
    }
    currentValue.add(newValue);
}

Your footer element won't inherently be fixed to the bottom of your viewport unless you style it that way.
So if you happen to have a page that doesn't have enough content to push it all the way down it'll end up somewhere in the middle of the viewport; looking very awkward and not sure what to do with itself, like my first day of high school.

Positioning the element by declaring the fixed rule is great if you always want your footer visible regardless of initial page height - but then remember to set a bottom margin so that it doesn't overlay the last bit of content on that page. This becomes tricky if your footer has a dynamic height; which is often the case with responsive sites since it's in the nature of elements to stack.

You'll find a similar problem with absolute positioning. And although it does take the element in question out of the natural flow of the document, it still won't fix it to the bottom of the screen should you find yourself with a page that has little to no content to flesh it out.

Consider achieving this by:

1. Declaring a height value for the <body> & <html> tags
2. Declaring a minimum-height value to the nested wrapper element, usually the element which wraps all your descendant elements contained within the body structure (this wouldn't include your footer element)

You should need to convert your PHP array to javascript array using PHP syntax json_encode. json_encode convert PHP array to JSON string

Single Dimension PHP array to javascript array

<?php
var $itemsarray= array("Apple", "Bear", "Cat", "Dog");
?>
<script>
var items= <?php echo json_encode($itemsarray); ?>;
console.log(items[2]); // Output: Bear
// OR
alert(items[0]); // Output: Apple
</script>

Multi Dimension PHP array to javascript array

<?php
var $itemsarray= array( 
               array('name'='Apple', 'price'=>'12345'),
               array('name'='Bear', 'price'=>'13344'),
               array('name'='Potato', 'price'=>'00440')
             );
?>


<script>
var items= <?php echo json_encode($itemsarray); ?>;
console.log(items[1][name]); // Output: Bear
// OR
alert(items[0][price]); // Output: Apple
</script>

For more detail, you can also check php array to javascript array

Found tar -cvf site1-$seqNumber.tar -C /var/www/ site1 as more friendlier solution than tar -cvf site1-$seqNumber.tar -C /var/www/site1 . (notice the . in the second solution) for the following reasons

• Tar file name can be insignificant as the original folder is now an archive entry
• Tar file name being insignificant to the content can now be used for other purposes like sequence numbers, periodical backup etc.

I had the similar issue. its resolved for me with a simple command.

lsnrctl start

The Network Adapter exception is caused because:

1. The database host name or port number is wrong (OR)
2. The database TNSListener has not been started. The TNSListener may be started with the lsnrctl utility.

Try to start the listener using the command prompt:

1. Click Start, type cmd in the search field, and when cmd shows up in the list of options, right click it and select ‘Run as Administrator’.
2. At the Command Prompt window, type lsnrctl start without the quotes and press Enter.
3. Type Exit and press Enter.

Hope it helps.

You may try this way. just use a function to get your object

def get_object(self, id):
    try:
        return Comment.objects.get(pk=id)
    except Comment.DoesNotExist:
        return False

You can use the following command. The SET will set the input from the user console to the variable comment and then you can use that variable using %comment%

SET /P comment=Comment: 
echo %comment%
pause

Change both Project and Package Properties ProtectionLevel to "DontSaveSensitive"

Another command under the cmd is:

easy_install pyqt5

I understand that this error can occur because of many different reasons. In my case it was because I uninstalled WSUS service from Server Roles and the whole IIS went down. After doing a bit of research I found that uninstalling WSUS removes a few dlls which are used to do http compression. Since those dlls were missing and the IIS was still looking for them I did a reset using the following command in CMD:

appcmd set config -section:system.webServer/httpCompression /-[name='xpress']

Bingo! The problem is sorted now. Dont forget to run it as an administrator. You might also need to do "iisreset" as well. Just in case.

Hope it helps others. Cheers

One more way to do it.

Add commit on the top of temporary commit and then do:

git rebase -i

To merge two commits into one (command will open text file with explicit instructions, edit it).

When in doubt, read the documentation:

filename = "C:\Temp\vblist.txt"

Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)

Do Until f.AtEndOfStream
  WScript.Echo f.ReadLine
Loop

f.Close

See String Formatting Operations:

%d is the format code for an integer. %f is the format code for a float.

%s prints the str() of an object (What you see when you print(object)).

%r prints the repr() of an object (What you see when you print(repr(object)).

For a float %s, %r and %f all display the same value, but that isn't the case for all objects. The other fields of a format specifier work differently as well:

>>> print('%10.2s' % 1.123) # print as string, truncate to 2 characters in a 10-place field.
        1.
>>> print('%10.2f' % 1.123) # print as float, round to 2 decimal places in a 10-place field.
      1.12

In my instance, the name of the connectionString in the web.config file was spelled wrong. This is the name of the database context Entity Framework uses. I guess this is the error you get when EF can't match up the connectionString name with the context.

Current version: Help | Change Memory Settings:

Since IntelliJ IDEA 15.0.4 you can also use: Help | Edit Custom VM Options...:

This will automatically create a copy of the .vmoptions file in the config folder and open a dialog to edit it.

Older versions:

IntelliJ IDEA 12 is a signed application, therefore changing options in Info.plist is no longer recommended, as the signature will not match and you will get issues depending on your system security settings (app will either not run, or firewall will complain on every start, or the app will not be able to use the system keystore to save passwords).

As a result of addressing IDEA-94050 a new way to supply JVM options was introduced in IDEA 12:

Now it can take VM options from ~/Library/Preferences/<appFolder>/idea.vmoptions and system properties from ~/Library/Preferences/<appFolder>/idea.properties.

For example, to use -Xmx2048m option you should copy the original .vmoptions file from /Applications/IntelliJ IDEA.app/bin/idea.vmoptions to ~/Library/Preferences/IntelliJIdea12/idea.vmoptions, then modify the -Xmx setting.

The final file should look like:

-Xms128m
-Xmx2048m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=64m
-XX:+UseCodeCacheFlushing
-XX:+UseCompressedOops

Copying the original file is important, as options are not added, they are replaced.

This way your custom options will be preserved between updates and application files will remain unmodified making signature checker happy.

Community Edition: ~/Library/Preferences/IdeaIC12/idea.vmoptions file is used instead.

So this is a little bit of a subtle point, because while Python only passes variables by value, every variable in Python is a reference. If you want to be able to change your values with a function call, what you need is a mutable object. For example:

l = [0]

def set_3(x):
    x[0] = 3

set_3(l)
print(l[0])

In the above code, the function modifies the contents of a List object (which is mutable), and so the output is 3 instead of 0.

I write this answer only to illustrate what 'by value' means in Python. The above code is bad style, and if you really want to mutate your values you should write a class and call methods within that class, as MPX suggests.

1) Go to C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A for VS2013

2) Copy the folders Include and Lib (you should check where are your folders in folder windows such as v7.1, v8, v6, etc.)

3) Paste them into C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC

I solved my problems like:

error lnk1104: cannot open file 'kernel32.lib'.
error c1083: Cannot open Windows.h

Thanks.

I had this error on a MVC Project. And after a long research i found out that the .cs file containing some of the classes i referenced in the main project had a Build Actions set to "Content" ...

After changing it "Content"->"Compile" the error disappeared.

This exception happened when I forgot to close the connections

For resource names and IDs, I use @PathParams. For optional variables, I use @QueryParams

In the debugger you don't need to add back slashes, the input field understands the special chars.

In java code you need to escape the special chars

You can save the current scroll amount and then set it later:

var tempScrollTop = $(window).scrollTop();

..//Your code

$(window).scrollTop(tempScrollTop);

Try an HTML table or use the following CSS :

<div id="bloc1" style="float:left">...</div>
<div id="bloc2">...</div>

(or use an HTML table)

Reserved.objects.filter(client=client_id).order_by('-check_in')

A hyphen "-" in front of "check_in" indicates descending order. Ascending order is implied.

We don't have to add an all() before filter(). That would still work, but you only need to add all() when you want all objects from the root QuerySet.

More on this here: https://docs.djangoproject.com/en/dev/topics/db/queries/#retrieving-specific-objects-with-filters

Sum of total_vm is 847170 and sum of rss is 214726, these two values are counted in 4kB pages, which means when oom-killer was running, you had used 214726*4kB=858904kB physical memory and swap space.

Since your physical memory is 1GB and ~200MB was used for memory mapping, it's reasonable for invoking oom-killer when 858904kB was used.

rss for process 2603 is 181503, which means 181503*4KB=726012 rss, was equal to sum of anon-rss and file-rss.

Use this:

echo "${@:2}"

The following syntax:

echo "${*:2}"

would work as well, but is not recommended, because as @Gordon already explained, that using *, it runs all of the arguments together as a single argument with spaces, while @ preserves the breaks between them (even if some of the arguments themselves contain spaces). It doesn't make the difference with echo, but it matters for many other commands.

Since IntelliJ 2016, the location is File | Settings | Build, Execution, Deployment | Compiler | Build process heap size.

std::string str(buffer, buffer + length);

Or, if the string already exists:

str.assign(buffer, buffer + length);

Edit: I'm still not completely sure I understand the question. But if it's something like what JoshG is suggesting, that you want up to length characters, or until a null terminator, whichever comes first, then you can use this:

std::string str(buffer, std::find(buffer, buffer + length, '\0'));

How about using $_POST = array(), which nullifies the data. The browser will still ask to reload, but there will be no data in the $_POST superglobal.

I had this same error message, turns out it was because I didn't have mixed mode auth enabled. I was on Windows Auth only. This is common in default MSSQL deployments for vSphere, and becomes an issue when upgrading to vSphere 5.1.

To change to mixed mode auth you can follow the instructions at http://support.webecs.com/kb/a374/how-do-i-configure-sql-server-express-to-enable-mixed-mode-authentication.aspx.

Practically speaking, if the keys were of type NaN, the browser will not change the order.

The following script will output "One", "Two", "Three":

var foo={"3":"Three", "1":"One", "2":"Two"};
for(bar in foo) {
    alert(foo[bar]);
}

Whereas the following script will output "Three", "One", "Two":

var foo={"@3":"Three", "@1":"One", "@2":"Two"};
for(bar in foo) {
    alert(foo[bar]);
}

The answer here is not clear, so I wanted to add more detail.

Using the link provided above, I performed the following step.

In my XML config manager I changed the "Provider" to SQLOLEDB.1 rather than SQLNCLI.1. This got me past this error.

One more thing, if you have used any function from certain package, mention that library.

from operator import itemgetter
from itertools import groupby

lki = [["A",0], ["B",1], ["C",0], ["D",2], ["E",2]]
lki.sort(key=itemgetter(1))

glo = [[x for x,y in g]
       for k,g in  groupby(lki,key=itemgetter(1))]

print glo

.

EDIT

Another solution that needs no import , is more readable, keeps the orders, and is 22 % shorter than the preceding one:

oldlist = [["A",0], ["B",1], ["C",0], ["D",2], ["E",2]]

newlist, dicpos = [],{}
for val,k in oldlist:
    if k in dicpos:
        newlist[dicpos[k]].extend(val)
    else:
        newlist.append([val])
        dicpos[k] = len(dicpos)

print newlist

I had the same issue on Windows 7. The cause was, that I had been connected to VPN using Cisco AnyConnect Secure Mobility Client.

I had the same exception installing using correct framework.

My solution was running cmd as administrator .... then it worked fine.

For me I had forgot to add closing quote

As the main answer is using CIFSPacket type, which is not (or no longer) available in C#, I wrote correct methods:

    static byte[] getBytes(object str)
    {
        int size = Marshal.SizeOf(str);
        byte[] arr = new byte[size];
        IntPtr ptr = Marshal.AllocHGlobal(size);

        Marshal.StructureToPtr(str, ptr, true);
        Marshal.Copy(ptr, arr, 0, size);
        Marshal.FreeHGlobal(ptr);

        return arr;
    }

    static T fromBytes<T>(byte[] arr)
    {
        T str = default(T);

        int size = Marshal.SizeOf(str);
        IntPtr ptr = Marshal.AllocHGlobal(size);

        Marshal.Copy(arr, 0, ptr, size);

        str = (T)Marshal.PtrToStructure(ptr, str.GetType());
        Marshal.FreeHGlobal(ptr);

        return str;
    }

Tested, they work.

You could try this.

In windows go to Administrative Tools->Services And see scroll down to where it says Oracle[instanceNameHere] and see if the listener and the service itself are running. You might have to start it. You can also set it to start automatically when you right-click on it and go to properties.

If you want to build your solution for x86 and x64, your solution must be configured for both platforms. Actually you just have an Any CPU configuration.

How to check the available configuration for a project

To check the available configuration for a given project, open the project file (*.csproj for example) and look for a PropertyGroup with the right Condition.

If you want to build in Release mode for x86, you must have something like this in your project file:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|x86' ">
  ...
</PropertyGroup>

I would like to show a little example on how is and == are involved in immutable types. Try that:

a = 19998989890
b = 19998989889 +1
>>> a is b
False
>>> a == b
True

is compares two objects in memory, == compares their values. For example, you can see that small integers are cached by Python:

c = 1
b = 1
>>> b is c
True

You should use == when comparing values and is when comparing identities. (Also, from an English point of view, "equals" is different from "is".)

If you are interested in portability between different SQL servers you should use ANSI SQL queries. String escaping in ANSI SQL is done by using double quotes ("). Unfortunately, this escaping method is not portable to MySQL, unless it is set in ANSI compatibility mode.

Personally, I always start my MySQL server with the --sql-mode='ANSI' argument since this allows for both methods for escaping. If you are writing queries that are going to be executed in a MySQL server that was not setup / is controlled by you, here is what you can do:

• Write all you SQL queries in ANSI SQL

• Enclose them in the following MySQL specific queries:

  SET @OLD_SQL_MODE=@@SQL_MODE;
  SET SESSION SQL_MODE='ANSI';
  -- ANSI SQL queries
  SET SESSION SQL_MODE=@OLD_SQL_MODE;
  

This way the only MySQL specific queries are at the beginning and the end of your .sql script. If you what to ship them for a different server just remove these 3 queries and you're all set. Even more conveniently you could create a script named: script_mysql.sql that would contain the above mode setting queries, source a script_ansi.sql script and reset the mode.

Try:

.bottom {
    position: fixed;
    bottom: 0;
}

The argument to split is a regular expression. The period is a regular expression metacharacter that matches anything, thus every character in line is considered to be a split character, and is thrown away, and all of the empty strings between them are thrown away (because they're empty strings). The result is that you have nothing left.

If you escape the period (by adding an escaped backslash before it), then you can match literal periods. (line.split("\\."))

Just a small correction for Marko's answer: exact number can't be produced out of some general calculations straight forward due to the next fact: Valid IP addresses should also not end with binary 0 or 1 sequences that have same length as zero sequence in subnet mask. So the final answer really depends on the total number of subnets (Marko's answer - 2 * total subnet count).

If your testing requires pulling quasi-real credit reports from the bureaus, the inactive SSNs of other answers won't work and you'll need designated test numbers.

I found this site Which appears to contain test social security numbers with associated test names and credit card numbers.

Transunion has a test environment you can link and send data to, including associated dummy credit reports. Sending a SSN to them with certain numbers in certain positions will automatically route the inquiry to their test environment Other credit bureaus will have similar systems in place.

encodeURI()/decodeURI and encodeURIComponent()/decodeURIComponent are utility functions to handle this. Read more here https://stackabuse.com/javascripts-encodeuri-function/

The server first tries to authenticate you by public key. That doesn't work (I guess you haven't set one up), so it then falls back to 'keyboard-interactive'. It should then ask you for a password, which presumably you're not getting right. Did you see a password prompt?

Use either. They are both equally (in)secure, as in many cases SERVER_NAME is just populated from HTTP_HOST anyway. I normally go for HTTP_HOST, so that the user stays on the exact host name they started on. For example if I have the same site on a .com and .org domain, I don't want to send someone from .org to .com, particularly if they might have login tokens on .org that they'd lose if sent to the other domain.

Either way, you just need to be sure that your webapp will only ever respond for known-good domains. This can be done either (a) with an application-side check like Gumbo's, or (b) by using a virtual host on the domain name(s) you want that does not respond to requests that give an unknown Host header.

The reason for this is that if you allow your site to be accessed under any old name, you lay yourself open to DNS rebinding attacks (where another site's hostname points to your IP, a user accesses your site with the attacker's hostname, then the hostname is moved to the attacker's IP, taking your cookies/auth with it) and search engine hijacking (where an attacker points their own hostname at your site and tries to make search engines see it as the ‘best’ primary hostname).

Apparently the discussion is mainly about $_SERVER['PHP_SELF'] and why you shouldn't use it in the form action attribute without proper escaping to prevent XSS attacks.

Pfft. Well you shouldn't use anything in any attribute without escaping with htmlspecialchars($string, ENT_QUOTES), so there's nothing special about server variables there.

You don't specify which OS.

Under Windows (for my application - a long running risk management application) we observed that we could go no further than 1280MB on Windows 32bit. I doubt that running a 32bit JVM under 64bit would make any difference.

We ported the app to Linux and we are running a 32bit JVM on 64bit hardware and have had a 2.2GB VM running pretty easily.

The biggest problem you may have is GC depending on what you are using memory for.

There is no feature in scp to filter files. For "advanced" stuff like this, I recommend using rsync:

rsync -av --exclude '*.svn' user@server:/my/dir .

(this line copy rsync from distant folder to current one)

Recent versions of rsync tunnel over an ssh connection automatically by default.

From a quick search, Oracle appears to use double quotes (", eg "table") and apparently requires the correct case—whereas, for anyone interested, MySQL defaults to using backticks (`) except when set to use double quotes for compatibility.

Make sure you're on the main thread.

If not, it will still save the button text. It will be there when you inspect the object in the debugger. But it won't actually update the view.

In case of trying to find tool to make your 2-space indented python script to a tab indented version, just use this online tool:

https://www.tutorialspoint.com/online_python_formatter.htm

Even though you are using ASMM, you can set a minimum size for the large pool (MMAN will not shrink it below that value). You can also try pinning some objects and increasing SGA_TARGET.

Adam Luter gave me the idea for this, but it actually turned out to be really simple:

img {
  width:  75px;
  height: auto;
}

IE6 now scales the image fine and this seems to be what all the other browsers use by default.

Thanks for both the answers though!

For Oracle 11g, I was able to change the column attribute as follows:

ALTER TABLE tablename MODIFY columnname datatype NOT NULL;

Otherwise abatichev's answer seemed good. You can't repeat the alter - it complains (at least in SQL Developer) that the column is already not null.

Just a thought, but you may check the influence of a ulimit -v option.

That is not an actual solution since it would limit address space available for all process, but that would allow you to check the behavior of your application with a limited virtual memory.

You can use git cherry-pick for this. 'cherry-pick' will apply a commit onto the branch your on now.

then do

git rebase --hard <SHA1 of A>

then apply the D and E commits.

git cherry-pick <SHA1 of D>
git cherry-pick <SHA1 of E>

This will skip out the B and C commit. Having said that it might be impossible to apply the D commit to the branch without B, so YMMV.

We found a different solution to a problem with the same symptom:

We saw this error when we updated the project from .net 4.7.1 to 4.7.2.

The problem was that even though we were not referencing System.Net.Http any more in the project, it was listed in the dependentAssembily section of our web.config. Removing this and any other unused assembly references from the web.config solved the problem.

Here is another option for executing Regex replacements, since not many people seem to notice the matches contain the location within the string:

    public static string ReplaceCaseInsensative( this string s, string oldValue, string newValue ) {
        var sb = new StringBuilder(s);
        int offset = oldValue.Length - newValue.Length;
        int matchNo = 0;
        foreach (Match match in Regex.Matches(s, Regex.Escape(oldValue), RegexOptions.IgnoreCase))
        {
            sb.Remove(match.Index - (offset * matchNo), match.Length).Insert(match.Index - (offset * matchNo), newValue);
            matchNo++;
        }
        return sb.ToString();
    }

When jumi (joomla plugin for PHP) compiles your code for some reason it removes all backslashes from your code. Such that something like $csv_output .= "\n"; becomes $csv_output .= "n";

Very annoying bug!

Use PHP_EOL instead to get the result you were after.

In fact, a variable is tuple (storage, scope, type, address, value):

storage     :   where is it stored, for example data, stack, heap...
scope       :   who can see us, for example global, local...
type        :   what is our type, for example int, int*...
address     :   where are we located
value       :   what is our value

Local scope could mean local to either the translational unit (source file), the function or the block depending on where its defined. To make variable visible to more than one function, it definitely has to be in either DATA or the BSS area (depending on whether its initialized explicitly or not, respectively). Its then scoped accordingly to either all function(s) or function(s) within source file.

You should always use "throw;" to rethrow the exceptions in .NET,

Refer this, http://weblogs.asp.net/bhouse/archive/2004/11/30/272297.aspx

Basically MSIL (CIL) has two instructions - "throw" and "rethrow":

• C#'s "throw ex;" gets compiled into MSIL's "throw"
• C#'s "throw;" - into MSIL "rethrow"!

Basically I can see the reason why "throw ex" overrides the stack trace.

Adaptive thresholding is important if the lighting is uneven across the image. My preprocessing using GraphicsMagic is mentioned in this post: https://groups.google.com/forum/#!topic/tesseract-ocr/jONGSChLRv4

GraphicsMagic also has the -lat feature for Linear time Adaptive Threshold which I will try soon.

Another method of thresholding using OpenCV is described here: http://docs.opencv.org/trunk/doc/py_tutorials/py_imgproc/py_thresholding/py_thresholding.html

I am an Ionic framework user and the one I found that would consistently provide the current controller's $scope is:

angular.element(document.querySelector('ion-view[nav-view="active"]')).scope()

I suspect this can be modified to fit most scenarios regardless of framework (or not) by finding the query that will target the specific DOM element(s) that are available only during a given controller instance.

As Uriel says, it is meant for a method in an abstract class that should be implemented in child class, but can be used to indicate a TODO as well.

There is an alternative for the first use case: Abstract Base Classes. Those help creating abstract classes.

Here's a Python 3 example:

class C(abc.ABC):
    @abc.abstractmethod
    def my_abstract_method(self, ...):
        ...

When instantiating C, you'll get an error because my_abstract_method is abstract. You need to implement it in a child class.

TypeError: Can't instantiate abstract class C with abstract methods my_abstract_method

Subclass C and implement my_abstract_method.

class D(C):
    def my_abstract_method(self, ...):
        ...

Now you can instantiate D.

C.my_abstract_method does not have to be empty. It can be called from D using super().

An advantage of this over NotImplementedError is that you get an explicit Exception at instantiation time, not at method call time.

You can use a serialize() function of JQuery:

    var datastring = $("#preview_form").serialize();
        $.ajax({
            type: "POST",
            url: "your url.php",
            data: datastring,
            success: function(data) {
                 alert('Data send');
            }
        });

And read in PHP:

echo $_POST['datastring']['dialog_box_textarea_1'];
echo $_POST['datastring']['radiobutton_1'];
........

And get ***data-**** to tag HTML5 you can see this example:

<div id="texto" data-author="Ricardo Miranda" data-date="2012-06-21">
<h4>Lorem ipsum</h4>
  <p>
    Lorem ipsum dolor sit amet, ius integre eligendi et,
    sea ut expetendis conclusionemque,
    mel at ornatus invenire. His ad moderatius definiebas omittantur,
    liber saepe albucius sea cu.
    Audire tamquam dolores vis ne, mediocrem consulatu eum ex.
    Duo te agam saepe convenire, et fugit iisque his.
 </p>

<script type="text/javascript">
$(function() {
    alert("The text is write " + $('#texto').data('author'));
});

And

<div id="texto" data-author='{"nombre":"Ricardo","apellido":"Miranda"}' data-date="2012-06-21">
   ...
</div>

<script type="text/javascript">
$(function() {
    alert("The text is write " + $('#texto').data('author').apellido + ", " +
        ('#texto').data('author').nombre);
});
</script>

To turn off foreign key constraint globally, do the following:

SET GLOBAL FOREIGN_KEY_CHECKS=0;

and remember to set it back when you are done

SET GLOBAL FOREIGN_KEY_CHECKS=1;

WARNING: You should only do this when you are doing single user mode maintenance. As it might resulted in data inconsistency. For example, it will be very helpful when you are uploading large amount of data using a mysqldump output.

Use "spacer" divs to surround the div you want to center. Works best with a fluid design. Be sure to give the spacers height, or else they will not work.

<style>
div.row{width=100%;}
dvi.row div{float=left;}
#content{width=80%;}
div.spacer{width=10%; height=10px;}
</style>

<div class="row">
<div class="spacer"></div>
<div id="content">...</div>
<div class="spacer"></div>
</div>

You may also need to make database containing table active

use [dbname]

otherwise you may get error (even if you specify database i.e. dbname.table )

FAILED Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. Unable to alter partition. Unable to alter partitions because table or database does not exist.

Not tested but should work

 products.sort((a,b)=>a.title.rendered > b.title.rendered)

why don't you store your values in HTML5 storage objects such as sessionStorage or localStorage, visit HTML5 Storage Doc to get more details. Using this you can store intermediate values temporarily/permanently locally and then access your values later.

To store values for a session:

sessionStorage.getItem('label')
sessionStorage.setItem('label', 'value')

or more permanently:

localStorage.getItem('label')
localStorage.setItem('label', 'value')

So you can store (temporarily) form data between multiple pages using HTML5 storage objects which you can even retain after reload..

1. Use require function when you need to load any class, function, or dependency.

2. Use include function when you want to load template-styled file

If you are still confused, just use require_once for all time.

Installing Android SDKs is done via the "Android SDK and AVD Manager"... there's a shortcut on Eclipse's "Window" menu, or you can run the .exe from the root of your existing Android SDK installation.

Yes I think installing the 2.3 SDK will fix your problem... you can install older SDKs at the same time. The important thing is that the structure of the SDK changed in 2.3 with some tools (such as ADB) moving from sdkroot\tools to sdkroot\platform-tools. Quite possibly the very latest ADT plugin isn't massively backwards-compatible re that change.

I found a simple way to fix that problem. At binding datagridview you've just done: datagridview.DataSource = dataSetName.Tables["TableName"];

If you code like:

datagridview.DataSource = dataSetName;
datagridview.DataMember = "TableName";

the datagridview will never load data again when filtering.

here is my implementation

public static byte[] intToByteArray(int a) {
    return BigInteger.valueOf(a).toByteArray();
}

public static int byteArrayToInt(byte[] b) {
    return new BigInteger(b).intValue();
}

during command line works. I'm using Ant to commit an artifact after build completes. Experienced the same issue... Manually excepting the cert did not work (Jenkins is funny that way). Add these options to your svn command:

--non-interactive

--trust-server-cert

There is no real limit -- everything is named with a 160-bit name. The size of the file must be representable in a 64 bit number so no real limit there either.

There is a practical limit, though. I have a repository that's ~8GB with >880,000 files and git gc takes a while. The working tree is rather large so operations that inspect the entire working directory take quite a while. This repo is only used for data storage, though, so it's just a bunch of automated tools that handle it. Pulling changes from the repo is much, much faster than rsyncing the same data.

I tried as you mentioned, but only first parameter is going through and rest all are appearing in the server as undefined. I am passing JSONWebToken as part of header.

.ajax({
    url: 'api/outletadd',
    type: 'post',
    data: { outletname:outletname , addressA:addressA , addressB:addressB, city:city , postcode:postcode , state:state , country:country , menuid:menuid },

        authorization: storedJWT
    },
    dataType: 'json',
    success: function (data){
        alert("Outlet Created");
    },
    error: function (data){
        alert("Outlet Creation Failed, please try again.");        
    }

    });

Even if you are sending all the right data (e.g. Selenium doesn't show up as an extension, you have a reasonable resolution/bit-depth, &c), there are a number of services and tools which profile visitor behaviour to determine whether the actor is a user or an automated system.

For example, visiting a site then immediately going to perform some action by moving the mouse directly to the relevant button, in less than a second, is something no user would actually do.

It might also be useful as a debugging tool to use a site such as https://panopticlick.eff.org/ to check how unique your browser is; it'll also help you verify whether there are any specific parameters that indicate you're running in Selenium.

In .Net Core, follow the instructions at https://docs.microsoft.com/en-us/aspnet/core/security/enforcing-ssl

In your startup.cs add the following:

// Requires using Microsoft.AspNetCore.Mvc;
public void ConfigureServices(IServiceCollection services)
{
    services.Configure<MvcOptions>(options =>
    {
        options.Filters.Add(new RequireHttpsAttribute());
    });`enter code here`

To redirect Http to Https, add the following in the startup.cs

// Requires using Microsoft.AspNetCore.Rewrite;
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();

    var options = new RewriteOptions()
       .AddRedirectToHttps();

    app.UseRewriter(options);

Standard Python dictionaries are inherently unordered, so what you're asking to do doesn't really make sense.

If you really, really know what you're doing, use

value_at_index = dic.values()[index]

Bear in mind that adding or removing an element can potentially change the index of every other element.

The method binascii.hexlify() will convert bytes to a bytes representing the ascii hex string. That means that each byte in the input will get converted to two ascii characters. If you want a true str out then you can .decode("ascii") the result.

I included an snippet that illustrates it.

import binascii

with open("addressbook.bin", "rb") as f: # or any binary file like '/bin/ls'
    in_bytes = f.read()
    print(in_bytes) # b'\n\x16\n\x04'
    hex_bytes = binascii.hexlify(in_bytes) 
    print(hex_bytes) # b'0a160a04' which is twice as long as in_bytes
    hex_str = hex_bytes.decode("ascii")
    print(hex_str) # 0a160a04

from the hex string "0a160a04" to can come back to the bytes with binascii.unhexlify("0a160a04") which gives back b'\n\x16\n\x04'

values = ['A', 'B', 'C', 'D', 'E']
values[0] # returns 'A'
values[2] # returns 'C'
# etc.

Peter's answer with an additional check! Of course, not 100% guaranteed!

var isJson = false;
outPutValue = ""
var objectConstructor = {}.constructor;
if(jsonToCheck.constructor === objectConstructor){
    outPutValue = JSON.stringify(jsonToCheck);
    try{
            JSON.parse(outPutValue);
            isJson = true;
    }catch(err){
            isJson = false;

    let trimString = function (string, length) {
      return string.length > length ? 
             string.substring(0, length) + '...' :
             string;
    };

Use Case,

let string = 'How to trim a string to N chars in Javascript';

trimString(string, 20);

//How to trim a string...

just do something like this:

        ListIterator<String> it = list1.listIterator();
        int index = -1;
        while (it.hasNext()) {
            index++;
            String value = it.next();
            //At this point the index can be checked for the current element.

        }

You don't need these two assigments:

cString1 = strToLower(cString1); 
cString2 = strToLower(cString2);

you are modifying the strings in place.

Warnings are because you are returning a char, and assigning to a char[] (which is equivalent to char*)

I suspect ^ doesn't work the way you think it does outside of a character class.

What you're telling it to do is replace everything that isn't an alphanumeric with an empty string, OR any leading space. I think what you mean to say is that spaces are ok to not replace - try moving the \s into the [] class.

From the documentation:

int getCellType() Deprecated. POI 3.15. Will return a CellType enum in the future.

Return the cell type. Will return CellType in version 4.0 of POI. For forwards compatibility, do not hard-code cell type literals in your code.

This is how I did with bootstrap popover with help of other bits around the net. Dynamically gets the title and content from die various products displayed on site. Each product or popover gets unique id. Popover will disappear when exiting the product( $this .pop) or the popover. Timeout is used where will display the popover until exit through product instead of popover.

$(".pop").each(function () {
        var $pElem = $(this);
        $pElem.popover(
            {
                html: true,
                trigger: "manual",
                title: getPopoverTitle($pElem.attr("id")),
                content: getPopoverContent($pElem.attr("id")),
                container: 'body',
                animation:false
            }
        );
    }).on("mouseenter", function () {
        var _this = this;
        $(this).popover("show");
        console.log("mouse entered");
        $(".popover").on("mouseleave", function () {
            $(_this).popover('hide');
        });
    }).on("mouseleave", function () {
        var _this = this;
        setTimeout(function () {
            if (!$(".popover:hover").length) {
                $(_this).popover("hide");
            }
        }, 100);
    });
    function getPopoverTitle(target) {
        return $("#" + target + "_content > h3.popover-title").html();
    };

    function getPopoverContent(target) {
        return $("#" + target + "_content > div.popover-content").html();
    };

A common idiom to change every element of a list looks like this:

for i in range(len(L)):
    item = L[i]
    # ... compute some result based on item ...
    L[i] = result

This can be rewritten using enumerate() as:

for i, item in enumerate(L):
    # ... compute some result based on item ...
    L[i] = result

See enumerate.

C# equivalent of your code is

  class Imagedata : PDFStreamEngine
  {
     // C# uses "base" keyword whenever Java uses "super" 
     // so instead of super(...) in Java we should call its C# equivalent (base):
     public Imagedata()
       : base(ResourceLoader.loadProperties("org/apache/pdfbox/resources/PDFTextStripper.properties", true)) 
     { }

     // Java methods are virtual by default, when C# methods aren't.
     // So we should be sure that processOperator method in base class 
     // (that is PDFStreamEngine)
     // declared as "virtual"
     protected override void processOperator(PDFOperator operations, List arguments)
     {
        base.processOperator(operations, arguments);
     }
  }

just write

<input type="number" step="0.1" lang="nb">

lang='nb" let you write your decimal numbers with comma or period

I understand you want to create stuff dynamically. That does not mean you have to actually construct DOM elements to do it. You can just make use of html to achieve what you want .

Look at the code below :

HTML:

<table border="0" cellpadding="0" width="100%" id='providersFormElementsTable'></table>

JS :

createFormElement("Nickname","nickname")

function createFormElement(labelText, id) {

$("#providersFormElementsTable").html("<tr><td>Nickname</td><td><input type='text' id='"+id+"' name='nickname'></td><lable id='"+labelText+"'></lable></td></tr>");
$('#providersFormElementsTable').append('<br />');
}

This one does what you want dynamically, it just needs the id and labelText to make it work, which actually must be the only dynamic variables as only they will be changing. Your DOM structure will always remain the same .

WORKING DEMO:

Moreover, when you use the process you mentioned in your post you get only [object Object]. That is because when you call createProviderFormFields , it is a function call and hence it's returning an object for you. You will not be seeing the text box as it needs to be added . For that you need to strip individual content form the object, then construct the html from it.

It's much easier to construct just the html and change the id s of the label and input according to your needs.

Trigger actions after countdown

Timer(Duration(seconds: 3), () {
  print("Yeah, this line is printed after 3 seconds");
});

Repeat actions

Timer.periodic(Duration(seconds: 5), (timer) {
  print(DateTime.now());
});

Trigger timer immediately

Timer(Duration(seconds: 0), () {
  print("Yeah, this line is printed immediately");
});

On my Mac Auto import option was not showing it was initially hidden

Android studio ->Preferences->editor->General->Auto Import

and then typed in searched field auto then auto import option appeared. And now auto import option is now always shown as default in Editor->General. hopefully this option will also help others. See attached screenshot

Also, anyone wanting to manually URLENCODE the address: http://code.google.com/apis/maps/documentation/webservices/index.html#BuildingURLs

You can use that to create specific rules that meet GM standards.

Try this :

    driver.findElement(By.id("email")).clear(); 
driver.findElement(By.id("email")).sendKeys("[email protected]");

For Ubuntu instances:

chmod 600 ec2-keypair.pem
ssh -v -i ec2-keypair.pem [email protected]

For other instances, you might have to use ec2-user instead of ubuntu.

Most EC2 Linux images I've used only have the root user created by default.

Easy peasy:

var date = DateTime.Parse("14/11/2011"); // may need some Culture help here
Console.Write(date.ToString("yyyy-MM-dd"));

Take a look at DateTime.ToString() method, Custom Date and Time Format Strings and Standard Date and Time Format Strings

string customFormattedDateTimeString = DateTime.Now.ToString("yyyy-MM-dd");

This is a simple example for adding the background image in a JFrame:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class BackgroundImageJFrame extends JFrame
{
    JButton b1;
    JLabel l1;

    public BackgroundImageJFrame()
    {
        setTitle("Background Color for JFrame");
        setSize(400,400);
        setLocationRelativeTo(null);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setVisible(true);

        /*
        One way
        -----------------
        setLayout(new BorderLayout());
        JLabel background=new JLabel(new ImageIcon("C:\\Users\\Computer\\Downloads\\colorful design.png"));
        add(background);
        background.setLayout(new FlowLayout());
        l1=new JLabel("Here is a button");
        b1=new JButton("I am a button");
        background.add(l1);
        background.add(b1);
        */

        // Another way
        setLayout(new BorderLayout());
        setContentPane(new JLabel(new ImageIcon("C:\\Users\\Computer\\Downloads\\colorful design.png")));
        setLayout(new FlowLayout());
        l1=new JLabel("Here is a button");
        b1=new JButton("I am a button");
        add(l1);
        add(b1);
        // Just for refresh :) Not optional!
        setSize(399,399);
        setSize(400,400);
    }

    public static void main(String args[])
    {
        new BackgroundImageJFrame();
    }
}

If you're using JSX with Harmony, you could do this:

<img className="image" src={`images/${this.props.image}`} />

Here you are writing the value of src as an expression.

NO,but there are some other options to implement default value. There are some good blog posts on the subject, but here are some specific examples.

// Both parameters are optional, use empty string for default value
func Concat1(a string, b int) string {
  if a == "" {
    a = "default-a"
  }
  if b == 0 {
    b = 5
  }

  return fmt.Sprintf("%s%d", a, b)
}

// a is required, b is optional.
// Only the first value in b_optional will be used.
func Concat2(a string, b_optional ...int) string {
  b := 5
  if len(b_optional) > 0 {
    b = b_optional[0]
  }

  return fmt.Sprintf("%s%d", a, b)
}

// A declarative default value syntax
// Empty values will be replaced with defaults
type Parameters struct {
  A string `default:"default-a"` // this only works with strings
  B string // default is 5
}

func Concat3(prm Parameters) string {
  typ := reflect.TypeOf(prm)

  if prm.A == "" {
    f, _ := typ.FieldByName("A")
    prm.A = f.Tag.Get("default")
  }

  if prm.B == 0 {
    prm.B = 5
  }

  return fmt.Sprintf("%s%d", prm.A, prm.B)
}

func Concat4(args ...interface{}) string {
  a := "default-a"
  b := 5

  for _, arg := range args {
    switch t := arg.(type) {
      case string:
        a = t
      case int:
        b = t
      default:
        panic("Unknown argument")
    }
  }

  return fmt.Sprintf("%s%d", a, b)
}

If you only want it to iterate over your HashMap, no need for a list:

HashMap<Integer, String> map = new HashMap<Integer, String>();
map.put (1, "Mark");
map.put (2, "Tarryn");
for (String s : map.values()) {
    System.out.println(s);
}

Of course, if you want to modify your map structurally (i.e. more than only changing the value for an existing key) while iterating, then you better use the "copy to ArrayList" method, since otherwise you'll get a ConcurrentModificationException. Or export as an array:

HashMap<Integer, String> map = new HashMap<Integer, String>();
map.put (1, "Mark");
map.put (2, "Tarryn");
for (String s : map.values().toArray(new String[]{})) {
    System.out.println(s);
}

There is now the built in ability to detect empty string with .isEmpty:

if emptyString.isEmpty {
    print("Nothing to see here")
}

There are also managed equivalents, but you haven't told us what you're programming in.

For .NET > 4.0 you can use

TimeSpan time = TimeSpan.FromSeconds(seconds);

//here backslash is must to tell that colon is
//not the part of format, it just a character that we want in output
string str = time .ToString(@"hh\:mm\:ss\:fff");

or if you want date time format then you can also do this

TimeSpan time = TimeSpan.FromSeconds(seconds);
DateTime dateTime = DateTime.Today.Add(time);
string displayTime = dateTime.ToString("hh:mm:tt");

For more you can check Custom TimeSpan Format Strings

I had a lot of trouble getting this to work. Dummy me, don't forget that old page - even for sub-requests - gets cached in your browser. Maybe obvious, but clear your browsers cache. After that, one can also use Header set Cache-Control "no-store" This was helpful to me while testing.

For people looking this up now:

It seems that now setting the User-Agent header is allowed since Firefox 43. See https://developer.mozilla.org/en-US/docs/Glossary/Forbidden_header_name for the current list of forbidden headers.

Double check if you have set and initial value for int and decimal values to be printed.

This sample is printing an empty line

declare @Number INT
print 'The number is : ' + CONVERT(VARCHAR, @Number)

And this sample is printing -> The number is : 1

declare @Number INT = 1
print 'The number is : ' + CONVERT(VARCHAR, @Number)

I was able to fix this with:

html { height: 100%; }

Actually the determination of what type of file a file is very complicated, so now the operating system can't just know. It can make lots of guesses based on -

• extension
• UTI
• MIME

But the command line doesn't bother with all that, because it runs on a limited backwards compatible layer, from when that fancy nonsense didn't mean anything. If you double click it sure, a modern OS can figure that out- but if you run it from a terminal then no, because the terminal doesn't care about your fancy OS specific file typing APIs.

Regarding the other points. It's a convenience, it's similarly possible to run

python3 path/to/your/script

If your python isn't in the path specified, then it won't work, but we tend to install things to make stuff like this work, not the other way around. It doesn't actually matter if you're under *nix, it's up to your shell whether to consider this line because it's a shellcode. So for example you can run bash under Windows.

You can actually ommit this line entirely, it just mean the caller will have to specify an interpreter. Also don't put your interpreters in nonstandard locations and then try to call scripts without providing an interpreter.

<script>
var someSession = '<%= Session["SessionName"].ToString() %>';
alert(someSession)
</script>

This code you can write in Aspx. If you want this in some js.file, you have two ways:

1. Make aspx file which writes complete JS code, and set source of this file as Script src
2. Make handler, to process JS file as aspx.

The default username is root. You can reset the root password if you do not know it: http://dev.mysql.com/doc/refman/5.0/en/resetting-permissions.html. You should not, however, use the root account from PHP, set up a limited permission user to do that: http://dev.mysql.com/doc/refman/5.1/en/adding-users.html

If MySql is running on the same computer as your webserver, you can just use "localhost" as the host

I was having such trouble managing my computer labs when the %PATH% environment variable approached 1024 characters that I wrote a Powershell script to fix it.

You can download the code here: https://gallery.technet.microsoft.com/scriptcenter/Edit-and-shorten-PATH-37ef3189

You can also use it as a simple way to safely add, remove and parse PATH entries. Enjoy.

If you don't care what groups the users were in, and just want a big ol' list of users - this does the job:

$Groups = Get-ADGroup -Filter {Name -like "AB*"}

$rtn = @(); ForEach ($Group in $Groups) {
    $rtn += (Get-ADGroupMember -Identity "$($Group.Name)" -Recursive)
}

Then the results:

$rtn | ft -autosize

To achieve a generic solution, why not do this:

$(':reset').live('click', function(){
    var $r = $(this);
    setTimeout(function(){ 
        $r.closest('form').find('.select2-offscreen').trigger('change'); 
    }, 10);
});

This way: You'll not have to make a new logic for each select2 on your application.

And, you don't have to know the default value (which, by the way, does not have to be "" or even the first option)

Finally, setting the value to :selected would not always achieve a true reset, since the current selected might well have been set programmatically on the client, whereas the default action of the form select is to return input element values to the server-sent ones.

EDIT: Alternatively, considering the deprecated status of live, we could replace the first line with this:

$('form:has(:reset)').on('click', ':reset', function(){

or better still:

$('form:has(:reset)').on('reset', function(){

PS: I personally feel that resetting on reset, as well as triggering blur and focus events attached to the original select, are some of the most conspicuous "missing" features in select2!

Here's a tutorial that shows you how to setup a custom font like @peter described: http://responsiveandroid.com/2012/03/15/custom-fonts-in-android-widgets.html

it also has consideration for potential memory leaks ala http://code.google.com/p/android/issues/detail?id=9904 . Also in the tutorial is an example for setting a custom font on a button.

My problem turned out to be that I was assigning as document.getElementById("myinput").Value = '1';

Notice the capital V in Value? Once I changed it to small case, i.e., value, the data started posting. Odd as it was not giving any JavaScript errors either.

I had a problem where I'm using a custom font and the underline created with the resource file trick (<u>Underlined text</u>) did work but Android managed to transform the underline to a sort of strike trough.

I used this answer to draw a border below the textview myself: https://stackoverflow.com/a/10732993/664449. Obviously this doesn't work for partial underlined text or multilined text.

The "in" in Linq-To-Sql uses a reverse logic compared to a SQL query.

Let's say you have a list of integers, and want to find the items that match those integers.

int[] numbers = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9 };

var items = from p in context.Items
                 where numbers.Contains(p.ItemId)
                select p;

Anyway, the above works fine in linq-to-sql but not in EF 1.0. Haven't tried it in EF 4.0

Here is a function I use in order to run at max n process in parallel (n=4 in the example):

max_children=4

function parallel {
  local time1=$(date +"%H:%M:%S")
  local time2=""

  # for the sake of the example, I'm using $2 as a description, you may be interested in other description
  echo "starting $2 ($time1)..."
  "$@" && time2=$(date +"%H:%M:%S") && echo "finishing $2 ($time1 -- $time2)..." &

  local my_pid=$$
  local children=$(ps -eo ppid | grep -w $my_pid | wc -w)
  children=$((children-1))
  if [[ $children -ge $max_children ]]; then
    wait -n
  fi
}

parallel sleep 5
parallel sleep 6
parallel sleep 7
parallel sleep 8
parallel sleep 9
wait

If max_children is set to the number of cores, this function will try to avoid idle cores.

As the commenters for the previous answer mentioned, you cannot simply add the line...

<location path="." inheritInChildApplications="false">

...just below <configuration>. Instead, you need to wrap the individual web.config sections for which you want to disable inheritance. For example:

<!-- disable inheritance for the connectionStrings section -->
<location path="." inheritInChildApplications="false">
   <connectionStrings>
   </connectionStrings>
</location>

<!-- leave inheritance enabled for appSettings -->
<appSettings>
</appSettings>

<!-- disable inheritance for the system.web section -->
<location path="." inheritInChildApplications="false">
   <system.web>
        <webParts>
        </webParts>
        <membership>
        </membership>

        <compilation>
        </compilation>
      </system.web>
 </location>

While <clear /> may work for some configuration sections, there are some that instead require a <remove name="..."> directive, and still others don't seem to support either. In these situations, it's probably appropriate to set inheritInChildApplications="false".

Welcome to the fickle world of SQL Server log management.

SOMETHING is wrong, though I don't think anyone will be able to tell you more than that without some additional information. For example, has this database ever been used for Transactional SQL Server replication? This can cause issues like this if a transaction hasn't been replicated to a subscriber.

In the interim, this should at least allow you to kill the log file:

1. Perform a full backup of your database. Don't skip this. Really.
2. Change the backup method of your database to "Simple"
3. Open a query window and enter "checkpoint" and execute
4. Perform another backup of the database
5. Change the backup method of your database back to "Full" (or whatever it was, if it wasn't already Simple)
6. Perform a final full backup of the database.

You should now be able to shrink the files (if performing the backup didn't do that for you).

Good luck!

If you want to ensure ui.newTab.index() is available in all situations (local and remote tabs), then call it in the activate function as the documentation says:

$("#tabs").tabs({
        activate: function(event, ui){
             alert(ui.newTab.index());
             // You can also use this to set another tab, see fiddle...
             // $("#other-tabs").tabs("option", "active", ui.newTab.index());                   
        },
});

http://jsfiddle.net/7v7n0v3j/

$(".class").click(function(){
    alert($(this).attr('id'));
});

only on jquery button click we can do this class should be written there

The way I see it, the only place for a nested query would be in the WHERE clause, so e.g.

SELECT country.name, country.headofstate
FROM country 
WHERE country.headofstate LIKE 'A%' AND 
country.id in (SELECT country_id FROM city WHERE population > 100000)

Apart from that, I have to agree with Adrian on: why the heck should you use nested queries?

perl -ple 's/^(..).*/$1/'

Well you could either add <a></a> tags and place the div inside it, adding an href if you want the div to act as a link. Or else just use Javascript and define an 'OnClick' function. But from the limited information provided, it's a bit hard to determine what the context of your problem is.

Why is GitHub rejecting my repo, even after I deleted the big file?

Git stores the full history of your project, so even if you 'delete' a file from your project, the Git repo still has a copy of the file in it's history, and if you try to push to another repository (like one hosted at GitHub) then Git requires the remote repo has the same history that your local repo does (ie the same big files in it's history).

How can I can I get GitHub to accept my repo?

You need to clean the Git history of your project locally, removing the unwanted big files from all of history, and then use only the 'cleaned' history going forward. The Git commit ids of the affected commits will change.

How do I clean big files out of my Git repo?

The best tool for cleaning unwanted big files out of Git history is the BFG Repo-Cleaner - it's a simpler, faster alternative to git-filter-branch specifically designed for removing unwanted files from Git history.

Carefully follow the usage instructions, the core part is just this:

$ java -jar bfg.jar --strip-blobs-bigger-than 100M my-repo.git

Any files over 100MB in size (that aren't in your latest commit) will be removed from your Git repository's history. You can then use git gc to clean away the dead data:

$ git gc --prune=now --aggressive

The BFG is typically at least 10-50x faster than running git-filter-branch, and generally a lot easier to use.

Full disclosure: I'm the author of the BFG Repo-Cleaner.

return only makes sense inside a function. There is no function in your code.

Also, your code is worthy if the Department of Redundancy Department. Assuming you move it to a proper function, this would be better:

return confirm(".json_encode($message).");

EDIT much much later: Changed code to use json_encode to ensure the message contents don't break just because of an apostrophe in the message.

After searching and browsing all day, the only one works is adding

I'm with Git downloaded from https://git-scm.com/ and set up ssh follow to the answer for instructions https://stackoverflow.com/a/26130250/4058484.

Once the generated public key is verified in my Bitbucket account, and by referring to the steps as explaned on http://www.bohyunkim.net/blog/archives/2518 I found that just 'git push' is working:

git clone https://[email protected]/me/test.git
cd test
cp -R ../dummy/* .
git add .
git pull origin master 
git commit . -m "my first git commit" 
git config --global push.default simple
git push

Shell respond are as below:

$ git push
Counting objects: 39, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (39/39), done.

It even works for to push on merging master to gh-pages in GitHub

git checkout gh-pages
git merge master
git push

This solved the issue:

remove.packages(c("ggplot2", "data.table"))
install.packages('Rcpp', dependencies = TRUE)
install.packages('ggplot2', dependencies = TRUE)
install.packages('data.table', dependencies = TRUE)

My answer is similar but different, there are a few ways to achieve toggling effect. I guess it depends on your circumstance. This may not be the best way for you in the end.

The missing piece you've been looking for is to create an if statement. This allows for you to toggle your text.

More on if statements here.

JSFiddle: http://jsfiddle.net/8u2jF/

Javascript:

var status = "less";

function toggleText()
{
    var text="Here is some text that I want added to the HTML file";

    if (status == "less") {
        document.getElementById("textArea").innerHTML=text;
        document.getElementById("toggleButton").innerText = "See Less";
        status = "more";
    } else if (status == "more") {
        document.getElementById("textArea").innerHTML = "";
        document.getElementById("toggleButton").innerText = "See More";
        status = "less"
    }
}

To add new changes to a new branch and push to remote:

git branch branch/name
git checkout branch/name
git push origin branch/name

Often times I forget to add the origin part to push and get confused why I don't see the new branch/commit in bitbucket

You have to manage client session on the client side. This means that you have to send authentication data with every request, and you probably, but not necessary have an in-memory cache on the server, which pairs auth data to user information like identity, permissions, etc...

This REST statelessness constraint is very important. Without applying this constraint, your server side application won't scale well, because maintaining every single client session will be its Achilles' heel.

According to the UI dialog documentation, the dialog plugin generates something like this:

<div class="ui-dialog ui-widget ui-widget-content ui-corner-all ui-draggable ui-resizable">
   <div class="ui-dialog-titlebar ui-widget-header ui-corner-all ui-helper-clearfix">
      <span id="ui-dialog-title-dialog" class="ui-dialog-title">Dialog title</span>
      <a class="ui-dialog-titlebar-close ui-corner-all" href="#"><span class="ui-icon ui-icon-closethick">close</span></a>
   </div>
   <div class="ui-dialog-content ui-widget-content" id="dialog_style1">
      <p>One content</p>
   </div>
</div>

That means what you can add to any class to exactly to first or second dialog using jQuery's closest() method. For example:

$('#dialog_style1').closest('.ui-dialog').addClass('dialog_style1');

$('#dialog_style2').closest('.ui-dialog').addClass('dialog_style2');

and then CSS it.

I'm a newbie in android developing but I hope my solution helps, it works on my condition perfectly. Im using Imageview and set it's background to "src" because im trying to make a frame animation. I got the same error but when I tried to code this it worked

int ImageID = this.Resources.GetIdentifier(questionPlay[index].Image.ToLower(), "anim", PackageName);
            imgView.SetImageResource(ImageID);
            AnimationDrawable animation = (AnimationDrawable)imgView.Drawable;
            animation.Start();
            animation.Dispose();

my approach was to use response.content (blob) and save to the file in binary mode

img_blob = requests.get(url, timeout=5).content
     with open(destination + '/' + title, 'wb') as img_file:
         img_file.write(img_blob)

Check out my python project that downloads images from unsplash.com based on keywords.

You can also do:

sqlite3 database.db -init dump.sql

EDIT: This fails the "constant space" constraint - it basically doubles the space required. I very much doubt that there's a solution which doesn't do that though, without wrecking the runtime complexity somewhere (e.g. making push/pop O(n)). Note that this doesn't change the complexity of the space required, e.g. if you've got a stack with O(n) space requirements, this will still be O(n) just with a different constant factor.

Non-constant-space solution

Keep a "duplicate" stack of "minimum of all values lower in the stack". When you pop the main stack, pop the min stack too. When you push the main stack, push either the new element or the current min, whichever is lower. getMinimum() is then implemented as just minStack.peek().

So using your example, we'd have:

Real stack        Min stack

5  --> TOP        1
1                 1
4                 2
6                 2
2                 2

After popping twice you get:

Real stack        Min stack

4                 2
6                 2
2                 2

Please let me know if this isn't enough information. It's simple when you grok it, but it might take a bit of head-scratching at first :)

(The downside of course is that it doubles the space requirement. Execution time doesn't suffer significantly though - i.e. it's still the same complexity.)

EDIT: There's a variation which is slightly more fiddly, but has better space in general. We still have the min stack, but we only pop from it when the value we pop from the main stack is equal to the one on the min stack. We only push to the min stack when the value being pushed onto the main stack is less than or equal to the current min value. This allows duplicate min values. getMinimum() is still just a peek operation. For example, taking the original version and pushing 1 again, we'd get:

Real stack        Min stack

1  --> TOP        1
5                 1
1                 2
4                 
6                 
2                 

Popping from the above pops from both stacks because 1 == 1, leaving:

Real stack        Min stack

5  --> TOP        1
1                 2
4                 
6                 
2                 

Popping again only pops from the main stack, because 5 > 1:

Real stack        Min stack

1                 1
4                 2
6                 
2                 

Popping again pops both stacks because 1 == 1:

Real stack        Min stack

4                 2
6                 
2                 

This ends up with the same worst case space complexity (double the original stack) but much better space usage if we rarely get a "new minimum or equal".

EDIT: Here's an implementation of Pete's evil scheme. I haven't tested it thoroughly, but I think it's okay :)

using System.Collections.Generic;

public class FastMinStack<T>
{
    private readonly Stack<T> stack = new Stack<T>();
    // Could pass this in to the constructor
    private readonly IComparer<T> comparer = Comparer<T>.Default;

    private T currentMin;

    public T Minimum
    {
        get { return currentMin; }
    }

    public void Push(T element)
    {
        if (stack.Count == 0 ||
            comparer.Compare(element, currentMin) <= 0)
        {
            stack.Push(currentMin);
            stack.Push(element);
            currentMin = element;
        }
        else
        {
            stack.Push(element);
        }
    }

    public T Pop()
    {
        T ret = stack.Pop();
        if (comparer.Compare(ret, currentMin) == 0)
        {
            currentMin = stack.Pop();
        }
        return ret;
    }
}

This function handels "HH:MM:SS" as well as "MM:SS" or "SS".

function hmsToSecondsOnly(str) {
    var p = str.split(':'),
        s = 0, m = 1;

    while (p.length > 0) {
        s += m * parseInt(p.pop(), 10);
        m *= 60;
    }

    return s;
}

Use:

Array.prototype.contains = function(x){
  var retVal = -1;

  // x is a primitive type
  if(["string","number"].indexOf(typeof x)>=0 ){ retVal = this.indexOf(x);}

  // x is a function
  else if(typeof x =="function") for(var ix in this){
    if((this[ix]+"")==(x+"")) retVal = ix;
  }

  //x is an object...
  else {
    var sx=JSON.stringify(x);
    for(var ix in this){
      if(typeof this[ix] =="object" && JSON.stringify(this[ix])==sx) retVal = ix;
    }
  }

  //Return False if -1 else number if numeric otherwise string
  return (retVal === -1)?false : ( isNaN(+retVal) ? retVal : +retVal);
}

I know it's not the best way to go, but since there is no native IComparable way to interact between objects, I guess this is as close as you can get to compare two entities in an array. Also, extending Array object might not be a wise thing to do, but sometimes it's OK (if you are aware of it and the trade-off).

Like this in simple way .

    $this->db->select('*');
    $this->db->from('certs');
    $this->db->where('certs.id NOT IN (SELECT id_cer FROM revokace)');

    return $this->db->get()->result();

2. Right click on the Visual Studio Project - Properties - Debug - (Enable Debuggers section) - mark "Enable the Visual Studio hosting process"
3. Save changes Ctrl + Shift + S) and run the project again.

P.S. I experienced the same problem when I was playing with the options to redirect the console input / output to text file and have selected the option Properties - Debug - (Start Action section) - Start external program. When I moved the Solution to another location on my computer the problem occurred because it was searching for an absolute path to the executable file. Restoring the Visual Studio Project default settings (see above) fixed the problem. For your reference I am using Visual Studio 2013 Professional.

Joda-Time & java.time

Both Joda-Time and java.time (new in Java 8) offer a LocalTime class to represent a time-of-day without any date or time zone.

Example code, identical code for both java.time and Joda-Time.

LocalTime localTime = new LocalTime( "14:40" );
LocalTime deadline = new LocalTime( "15:30" );
boolean meetsDeadline = localTime.isBefore( deadline );

About java.time

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

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

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

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes. Hibernate 5 & JPA 2.2 support java.time.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

Use the FOR command to echo a file line by line, and with the 'skip' option to miss a number of starting lines...

FOR /F "skip=1" %i in (file2.txt) do @echo %i

You could redirect the output of a batch file, containing something like...

FOR /F %%i in (file1.txt) do @echo %%i
FOR /F "skip=1" %%i in (file2.txt) do @echo %%i

Note the double % when a FOR variable is used within a batch file.

No, you can't make the img stretch to fit the div and simultaneously achieve the inverse. You would have an infinite resizing loop. However, you could take some notes from other answers and implement some min and max dimensions but that wasn't the question.

You need to decide if your image will scale to fit its parent or if you want the div to expand to fit its child img.

Using this block tells me you want the image size to be variable so the parent div is the width an image scales to. height: auto is going to keep your image aspect ratio in tact. if you want to stretch the height it needs to be 100% like this fiddle.

img {
    width: 100%;
    height: auto;
}

Figure out what version of python3 you have installed:

yum search pip

and then install the best match. Use reqoquery to find name of resulting pip3.e.g

repoquery -l python36u-pip

tells me to use pip3.6 instead of pip3

I have this error too, i put a commit for not push empty project like a lot of people do but doesn't work

YOu can also rewrite it like this

FROM Resource r WHERE r.ResourceNo IN
        ( 
            SELECT m.ResourceNo FROM JobMember m
            JOIN Job j ON j.JobNo = m.JobNo
            WHERE j.ProjectManagerNo = @UserResourceNo 
            OR
            j.AlternateProjectManagerNo = @UserResourceNo

            Union All

            SELECT m.ResourceNo FROM JobMember m
            JOIN JobTask t ON t.JobTaskNo = m.JobTaskNo
            WHERE t.TaskManagerNo = @UserResourceNo
            OR
            t.AlternateTaskManagerNo = @UserResourceNo

        )

Also a return table is expected in your RETURN statement

If you use two databases you can add another DataClasses.dbml and map the second database into it.
It works.

I think it should be the case. To erase the character, you should use replace(".", "") instead.

This might help, I used to fi my files like this: http://security102.blogspot.ru/2010/04/findreplace-of-nul-objects-in-notepad.html

Basically you need to replace \x00 characters with regular expressions

if the array looks like:

• $featured["fruit"] = "orange";
• $featured["fruit"] = "banana";
• $featured["vegetable"] = "carrot";

the $key will hold the type (fruit or vegetable) for each array value (orange, banana or carrot)

You can select all Sku elements of your myLines list and then convert the result to an array.

string[] mySKUsArray = myLines.Select(x=>x.Sku).ToArray();

A framework or other similar schema will run/interpret a script to do a task. A program is compiled and run by a machine to do a task

Your regular expression [a-z] doesn't match dkoe since it only matches Strings of lenght 1. Use something like [a-z]+.

maybe this is what u want?

<a href="#" id="bottle" onclick="document.location=this.id+'.html';return false;" >
    <img src="../images/bottle.jpg" alt="bottle" class="thumbnails" />
</a>

For those who want to do this in pure javascript, look at:

Using standard KeyboardEvent

As Joe comment it, KeyboardEvent is now the standard.

Same example to fire an enter (keyCode 13):

const ke = new KeyboardEvent('keydown', {
    bubbles: true, cancelable: true, keyCode: 13
});
document.body.dispatchEvent(ke);

You can use this page help you to find the right keyboard event.

Outdated answer:

• initKeyboardEvent for IE9+, Chrome and Safari
• initKeyEvent for Firefox

You can do something like (here for Firefox)

var ev = document.createEvent('KeyboardEvent');
// Send key '13' (= enter)
ev.initKeyEvent(
    'keydown', true, true, window, false, false, false, false, 13, 0);
document.body.dispatchEvent(ev);

As it was said already @INC is an array and you're free to add anything you want.

My CGI REST script looks like:

#!/usr/bin/perl
use strict;
use warnings;
BEGIN {
    push @INC, 'fully_qualified_path_to_module_wiht_our_REST.pm';
}
use Modules::Rest;
gone(@_);

Subroutine gone is exported by Rest.pm.

just change the extension to .bmp.

Do this:

ByteArrayOutputStream bytes = new ByteArrayOutputStream();
_bitmapScaled.compress(Bitmap.CompressFormat.PNG, 40, bytes);

//you can create a new file name "test.BMP" in sdcard folder.
File f = new File(Environment.getExternalStorageDirectory()
                        + File.separator + "test.bmp")

It'll sound that I'm just fooling around, but try it once and it'll get saved in BMP format. Cheers!

It's actually not too complicated...

Say you're on domain example.com, and you want to make a request to domain example.net. To do so, you need to cross domain boundaries, a no-no in most of browserland.

The one item that bypasses this limitation is <script> tags. When you use a script tag, the domain limitation is ignored, but under normal circumstances, you can't really do anything with the results, the script just gets evaluated.

Enter JSONP. When you make your request to a server that is JSONP enabled, you pass a special parameter that tells the server a little bit about your page. That way, the server is able to nicely wrap up its response in a way that your page can handle.

For example, say the server expects a parameter called callback to enable its JSONP capabilities. Then your request would look like:

http://www.example.net/sample.aspx?callback=mycallback

Without JSONP, this might return some basic JavaScript object, like so:

{ foo: 'bar' }

However, with JSONP, when the server receives the "callback" parameter, it wraps up the result a little differently, returning something like this:

mycallback({ foo: 'bar' });

As you can see, it will now invoke the method you specified. So, in your page, you define the callback function:

mycallback = function(data){
  alert(data.foo);
};

And now, when the script is loaded, it'll be evaluated, and your function will be executed. Voila, cross-domain requests!

It's also worth noting the one major issue with JSONP: you lose a lot of control of the request. For example, there is no "nice" way to get proper failure codes back. As a result, you end up using timers to monitor the request, etc, which is always a bit suspect. The proposition for JSONRequest is a great solution to allowing cross domain scripting, maintaining security, and allowing proper control of the request.

These days (2015), CORS is the recommended approach vs. JSONRequest. JSONP is still useful for older browser support, but given the security implications, unless you have no choice CORS is the better choice.

The following worked for me

const conString = "postgres://YourUserName:YourPassword@YourHostname:5432/YourDatabaseName";

Like mentioned earlier, I'd recommend boost lexical_cast. Not only does it have a fairly nice syntax:

#include <boost/lexical_cast.hpp>
std::string s = boost::lexical_cast<std::string>(i);

it also provides some safety:

try{
  std::string s = boost::lexical_cast<std::string>(i);
}catch(boost::bad_lexical_cast &){
 ...
}

I agree with Tom van der Woerdt. You could use CSS to hide the video (visibility:hidden or overflow:hidden in a div wrapper constrained by height), but that may violate Youtube's policies. Additionally, how could you control the audio (pause, stop, volume, etc.)?

You could instead turn to resources such as http://www.houndbite.com/ to manage audio.

I think this is better, following the good practices of passing parameters to the query:

BookingDates::whereRaw('email = ? or name like ?', [$request->email,"%{$request->name}%"])->get();

You can see it in the documentation, Laravel 5.5.

You can also use the Laravel scout and make it easier with search. Here is the documentation.

We can use geobytes.com to get the location using user IP address

$user_ip = getIP();
$meta_tags = get_meta_tags('http://www.geobytes.com/IPLocator.htm?GetLocation&template=php3.txt&IPAddress=' . $user_ip);
echo '<pre>';
print_r($meta_tags);

it will return data like this

function getIP(){
if (isset($_SERVER["HTTP_X_FORWARDED_FOR"])){
    $pattern = "/^(([1-9]?[0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5]).){3}([1-9]?[0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$/";
    if(preg_match($pattern, $_SERVER["HTTP_X_FORWARDED_FOR"])){
            $userIP = $_SERVER["HTTP_X_FORWARDED_FOR"];
    }else{
            $userIP = $_SERVER["REMOTE_ADDR"];
    }
}
else{
  $userIP = $_SERVER["REMOTE_ADDR"];
}
return $userIP;
}

Use the format() function with a '02x' format.

>>> format(255, '02x')
'ff'
>>> format(2, '02x')
'02'

The 02 part tells format() to use at least 2 digits and to use zeros to pad it to length, x means lower-case hexadecimal.

The Format Specification Mini Language also gives you X for uppercase hex output, and you can prefix the field width with # to include a 0x or 0X prefix (depending on wether you used x or X as the formatter). Just take into account that you need to adjust the field width to allow for those extra 2 characters:

>>> format(255, '02X')
'FF'
>>> format(255, '#04x')
'0xff'
>>> format(255, '#04X')
'0XFF'

Since these are member functions, call it as a member function on the instance, self.

def isNear(self, p):
    self.distToPoint(p)
    ...

one way: List.AddRange() depending on the types?

I just found a solution for jaxrs-ri-2.16 - simply use

String output = response.readEntity(String.class)

this delivers the content as expected.

Fastest way is to use MySQL bulk loader by "load data infile" statement. It is the fastest way by far than any way you can come up with in Python. If you have to use Python, you can call statement "load data infile" from Python itself.

There are three ways of underling the text in TextView.

1. SpannableString

2. setPaintFlags(); of TextView

3. Html.fromHtml();

Let me explain you all approaches :

1st Approach

For underling the text in TextView you have to use SpannableString

String udata="Underlined Text";
SpannableString content = new SpannableString(udata);
content.setSpan(new UnderlineSpan(), 0, udata.length(), 0);
mTextView.setText(content);

2nd Approach

You can make use of setPaintFlags method of TextView to underline the text of TextView.

For eg.

mTextView.setPaintFlags(mTextView.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);
mTextView.setText("This text will be underlined");

You can refer constants of Paint class if you want to strike thru the text.

3rd Approach

Make use of Html.fromHtml(htmlString);

String htmlString="<u>This text will be underlined</u>";
mTextView.setText(Html.fromHtml(htmlString));

OR

txtView.setText(Html.fromHtml("<u>underlined</u> text"));

for C use /// in gcc.

#include <windows.h>

then use Sleep(); /// Sleep() with capital S. not sleep() with s .

//Sleep(1000) is 1 sec /// maybe.

clang supports sleep(), sleep(1) is for 1 sec time delay/wait.

My solution is put those imports in __init__.py of lib:

in file: __init__.py
import mod1

Then,

import lib
lib.mod1

would work fine.

Apart from a database, you can also have following options to save user related settings

1. registry under HKEY_CURRENT_USER

2. in a file in AppData folder

3. using Settings file in WPF and by setting its scope as User

I was using the following:

from module import Foo

foo_instance = Foo()

but to get rid of circular reference I did the following and it worked:

import module.foo

foo_instance = foo.Foo()

Here is the sample of your answer: http://plnkr.co/edit/MKugkgCSpdZFefSeDRi7?p=preview

<span>Date Of Birth: {{DateOfBirth | date:"dd-MM-yyyy"}}</span>
<input type="text" datepicker-popup="dd/MM/yyyy" ng-model="DateOfBirth" class="form-control" />

and then in the controller:

$scope.DateOfBirth = new Date();

make Sublime Text 3 your default text editor: (Restart required)

Edit:

Are you trying to do sth like this? See: http://twitter.github.com/bootstrap/javascript.html#tabs

See the working example: http://jsfiddle.net/U6aKT/

<a href="#id">go to id</a>
<div style="margin-top:2000px;"></div>
<a id="id">id</a>

public ResponseEntity<?> ApiCall(@PathVariable(name = "id") long id) {
    JSONObject resp = new JSONObject();
    resp.put("status", 0);
    resp.put("id", id);

    return new ResponseEntity<String>(resp.toString(), HttpStatus.CREATED);
}

SharedPreferences are stored in an xml file in the app data folder, i.e.

/data/data/YOUR_PACKAGE_NAME/shared_prefs/YOUR_PREFS_NAME.xml

or the default preferences at:

/data/data/YOUR_PACKAGE_NAME/shared_prefs/YOUR_PACKAGE_NAME_preferences.xml

SharedPreferences added during runtime are not stored in the Eclipse project.

Note: Accessing /data/data/<package_name> requires superuser privileges

Something like:

clients.stream.filter(c->{
   users.stream.filter(u->u.getName().equals(c.getName()).count()>0
}).collect(Collectors.toList());

This is however not an awfully efficient way to do it. Unless the collections are very small, you will be better of building a set of user names and using that in the condition.

I use environment for that. It works automatically and you don't have to create new injectable service and most usefull for me, don't need to import via constructor.

1) Create environment variable in your environment.ts

export const environment = {
    ...
    // runtime variables
    isContentLoading: false,
    isDeployNeeded: false
}

2) Import environment.ts in *.ts file and create public variable (i.e. "env") to be able to use in html template

import { environment } from 'environments/environment';

@Component(...)
export class TestComponent {
    ...
    env = environment;
}

3) Use it in template...

<app-spinner *ngIf='env.isContentLoading'></app-spinner>

in *.ts ...

env.isContentLoading = false 

(or just environment.isContentLoading in case you don't need it for template)

You can create your own set of globals within environment.ts like so:

export const globals = {
    isContentLoading: false,
    isDeployNeeded: false
}

and import directly these variables (y)

Without reading your code but just your scenario, I would solve by using localStorage. Here's an example, I'll use prompt() for short.

On page1:

window.onload = function() {
   var getInput = prompt("Hey type something here: ");
   localStorage.setItem("storageName",getInput);
}

On page2:

window.onload = alert(localStorage.getItem("storageName"));

You can also use cookies but localStorage allows much more spaces, and they aren't sent back to servers when you request pages.

You can use the following to only include valid characters:

SQL

SELECT * FROM @Table
WHERE Col NOT LIKE '%[^0-9.]%'

For Unicode support:

public class HexadecimalEncoding
{
    public static string ToHexString(string str)
    {
        var sb = new StringBuilder();

        var bytes = Encoding.Unicode.GetBytes(str);
        foreach (var t in bytes)
        {
            sb.Append(t.ToString("X2"));
        }

        return sb.ToString(); // returns: "48656C6C6F20776F726C64" for "Hello world"
    }

    public static string FromHexString(string hexString)
    {
        var bytes = new byte[hexString.Length / 2];
        for (var i = 0; i < bytes.Length; i++)
        {
            bytes[i] = Convert.ToByte(hexString.Substring(i * 2, 2), 16);
        }

        return Encoding.Unicode.GetString(bytes); // returns: "Hello world" for "48656C6C6F20776F726C64"
    }
}

I believe best practice these days is H/5 * * * *, which means every 5 minutes with a hashing factor to avoid all jobs starting at EXACTLY the same time.

The pointer-events CSS property is a little lacking when it comes to support (caniuse.com), but it's very succinct:

.my-link { pointer-events: none; } 

I had the same issue. I think it would be appropriate to check whether your class can be compiled or not. Click recompile (Ctrl+Shift+F9 by default). If its not working then you have to investigate why it isn't compiling.

In my case the code wasn't autocompiling because there were hidden errors with compilation (they weren't shown in logs anywhere and maven clean-install was working). The rootcause was incorrect Project Structure -> Modules configuration, so Intellij Idea wasn't able to build it according to this configuration.

UIImage(data:imageData,scale:1.0) presuming the image's scale is 1.

In swift 4.2, use below code for get Data().

You have a bad table design. You can't autoincrement a string, that doesn't make any sense. You have basically two options:

1.) change type of ID to int instead of string
2.) not recommended!!! - handle autoincrement by yourself. You first need to get the latest value from the database, parse it to the integer, increment it and attach it to the entity as a string again. VERY BAD idea

First option requires to change every table that has a reference to this table, BUT it's worth it.

Other than the options mentioned above, there are a couple of other Solutions.

1. Modifying the project file (.CsProj) file

MSBuild supports the EnvironmentName Property which can help to set the right environment variable as per the Environment you wish to Deploy. The environment name would be added in the web.config during the Publish phase.

Simply open the project file (*.csProj) and add the following XML.

<!-- Custom Property Group added to add the Environment name during publish
  The EnvironmentName property is used during the publish for the Environment variable in web.config
  -->
  <PropertyGroup Condition=" '$(Configuration)' == '' Or '$(Configuration)' == 'Debug'">
    <EnvironmentName>Development</EnvironmentName>
  </PropertyGroup>
  <PropertyGroup Condition=" '$(Configuration)' != '' AND '$(Configuration)' != 'Debug' ">
    <EnvironmentName>Production</EnvironmentName>
  </PropertyGroup>

Above code would add the environment name as Development for Debug configuration or if no configuration is specified. For any other Configuration the Environment name would be Production in the generated web.config file. More details here

2. Adding the EnvironmentName Property in the publish profiles.

We can add the <EnvironmentName> property in the publish profile as well. Open the publish profile file which is located at the Properties/PublishProfiles/{profilename.pubxml} This will set the Environment name in web.config when the project is published. More Details here

<PropertyGroup>
  <EnvironmentName>Development</EnvironmentName>
</PropertyGroup>

3. Command line options using dotnet publish

Additionaly, we can pass the property EnvironmentName as a command line option to the dotnet publish command. Following command would include the environment variable as Development in the web.config file.

dotnet publish -c Debug -r win-x64 /p:EnvironmentName=Development

You got some of these right, but whoever wrote the questions tricked you on at least one question:

• global variables -------> data (correct)
• static variables -------> data (correct)
• constant data types -----> code and/or data. Consider string literals for a situation when a constant itself would be stored in the data segment, and references to it would be embedded in the code
• local variables(declared and defined in functions) --------> stack (correct)
• variables declared and defined in main function -----> heap also stack (the teacher was trying to trick you)
• pointers(ex: char *arr, int *arr) -------> heap data or stack, depending on the context. C lets you declare a global or a static pointer, in which case the pointer itself would end up in the data segment.
• dynamically allocated space(using malloc, calloc, realloc) --------> stack heap

It is worth mentioning that "stack" is officially called "automatic storage class".

If you are importing or you have an array (of type string) in your code and you have to convert it into arraylist (offcourse string) then use of collections is better. like this:

String array1[] = getIntent().getExtras().getStringArray("key1"); or String array1[] = ... then

List allEds = new ArrayList(); Collections.addAll(allEds, array1);

The Google idea is a nice one, but has problems.

I can successfully open a Google calendar event screen - but only on the main desktop version, and it doesn't display properly on iPhone Safari. The Google mobile calendar, which does display properly on Safari, doesn't seem to work with the API to add events.

For the moment, I can't see a good way out of this one.

IE8's HTML5 support is limited, but Internet Explorer 9 has just been released and has strong support for the new emerging HTML5 technologies.

An alternative version of the ordinal function could be as follows:

function toCardinal(num) {
    var ones = num % 10;
    var tens = num % 100;

    if (tens < 11 || tens > 13) {
        switch (ones) {
            case 1:
                return num + "st";
            case 2:
                return num + "nd";
            case 3:
                return num + "rd";
        }
    }

    return num + "th";
}

The variables are named more explicitly, uses camel case convention, and might be faster.

In order to create modular style sheets that are not dependent on the absolute location of a resource, authors may use relative URIs. Relative URIs (as defined in [RFC3986]) are resolved to full URIs using a base URI. RFC 3986, section 5, defines the normative algorithm for this process. For CSS style sheets, the base URI is that of the style sheet, not that of the source document.

For example, suppose the following rule:

body { background: url("yellow") }

is located in a style sheet designated by the URI:

http://www.example.org/style/basic.css

The background of the source document's BODY will be tiled with whatever image is described by the resource designated by the URI

http://www.example.org/style/yellow

User agents may vary in how they handle invalid URIs or URIs that designate unavailable or inapplicable resources.

Taken from the CSS 2.1 spec.

Well, I faced the same issue whenever I change my login password.

Below is the command I need to run to fix this issue:-

After running above command it asks me again my updated username and password.

You can use following:

angular.element(domElement).scope() to get the current scope for the element

angular.element(domElement).injector() to get the current app injector

angular.element(domElement).controller() to get a hold of the ng-controller instance.

getText(): Get the visible (i.e. not hidden by CSS) innerText of this element, including sub-elements, without any leading or trailing whitespace.

getAttribute(String attrName): Get the value of a the given attribute of the element. Will return the current value, even if this has been modified after the page has been loaded. More exactly, this method will return the value of the given attribute, unless that attribute is not present, in which case the value of the property with the same name is returned (for example for the "value" property of a textarea element). If neither value is set, null is returned. The "style" attribute is converted as best can be to a text representation with a trailing semi-colon. The following are deemed to be "boolean" attributes, and will return either "true" or null: async, autofocus, autoplay, checked, compact, complete, controls, declare, defaultchecked, defaultselected, defer, disabled, draggable, ended, formnovalidate, hidden, indeterminate, iscontenteditable, ismap, itemscope, loop, multiple, muted, nohref, noresize, noshade, novalidate, nowrap, open, paused, pubdate, readonly, required, reversed, scoped, seamless, seeking, selected, spellcheck, truespeed, willvalidate Finally, the following commonly mis-capitalized attribute/property names are evaluated as expected: "class" "readonly"

getText() return the visible text of the element.

getAttribute(String attrName) returns the value of the attribute passed as parameter.

You can just try this :

str.replace(/[.#]/g, 'replacechar');

this will replace .,- and # with your replacechar !

I know this is late, but I actually really like using:

import time
start = time.time()

##### your timed code here ... #####

print "Process time: " + (time.time() - start)

time.time() gives you seconds since the epoch. Because this is a standardized time in seconds, you can simply subtract the start time from the end time to get the process time (in seconds). time.clock() is good for benchmarking, but I have found it kind of useless if you want to know how long your process took. For example, it's much more intuitive to say "my process takes 10 seconds" than it is to say "my process takes 10 processor clock units"

>>> start = time.time(); sum([each**8.3 for each in range(1,100000)]) ; print (time.time() - start)
3.4001404476250935e+45
0.0637760162354
>>> start = time.clock(); sum([each**8.3 for each in range(1,100000)]) ; print (time.clock() - start)
3.4001404476250935e+45
0.05

In the first example above, you are shown a time of 0.05 for time.clock() vs 0.06377 for time.time()

>>> start = time.clock(); time.sleep(1) ; print "process time: " + (time.clock() - start)
process time: 0.0
>>> start = time.time(); time.sleep(1) ; print "process time: " + (time.time() - start)
process time: 1.00111794472

In the second example, somehow the processor time shows "0" even though the process slept for a second. time.time() correctly shows a little more than 1 second.

This one worked for me:

def list = [1,2,3,4]
for(item in list){
    println item
}

PDFJet offers an open-source version of their library that should be able to handle any basic PDF generation task. It's a purely Java-based solution and it is stated to be compatible with Android. There is a commercial version with some additional features that does not appear to be too expensive.

Outside of character classes, it is conventional not to escape hyphens. If I saw an escaped hyphen outside of a character class, that would suggest to me that it was written by someone who was not very comfortable with regexes.

Inside character classes, I don't think one way is conventional over the other; in my experience, it usually seems to be to put either first or last, as in [-._:] or [._:-], to avoid the backslash; but I've also often seen it escaped instead, as in [._\-:], and I wouldn't call that unconventional.

As a simple approximation you could use

grep -A100000 TERMINATE file

which greps for TERMINATE and outputs up to 100000 lines following that line.

From man page

-A NUM, --after-context=NUM

Print NUM lines of trailing context after matching lines. Places a line containing a group separator (--) between contiguous groups of matches. With the -o or --only-matching option, this has no effect and a warning is given.

i believe the reason it is not working in your example is that you have imported datetime like so :

from datetime import datetime

this leads to the error you see

In [30]: isinstance(x, datetime.date)
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/<ipython-input-30-9a298ea6fce5> in <module>()
----> 1 isinstance(x, datetime.date)

TypeError: isinstance() arg 2 must be a class, type, or tuple of classes and types

if you simply import like so :

import datetime

the code will run as shown in all of the other answers

In [31]: import datetime

In [32]: isinstance(x, datetime.date)
Out[32]: True

In [33]: 

In ES6 use:

import path from 'path';

GRANTs on different objects are separate. GRANTing on a database doesn't GRANT rights to the schema within. Similiarly, GRANTing on a schema doesn't grant rights on the tables within.

If you have rights to SELECT from a table, but not the right to see it in the schema that contains it then you can't access the table.

The rights tests are done in order:

Do you have `USAGE` on the schema? 
    No:  Reject access. 
    Yes: Do you also have the appropriate rights on the table? 
        No:  Reject access. 
        Yes: Check column privileges.

Your confusion may arise from the fact that the public schema has a default GRANT of all rights to the role public, which every user/group is a member of. So everyone already has usage on that schema.

The phrase:

(assuming that the objects' own privilege requirements are also met)

Is saying that you must have USAGE on a schema to use objects within it, but having USAGE on a schema is not by itself sufficient to use the objects within the schema, you must also have rights on the objects themselves.

It's like a directory tree. If you create a directory somedir with file somefile within it then set it so that only your own user can access the directory or the file (mode rwx------ on the dir, mode rw------- on the file) then nobody else can list the directory to see that the file exists.

If you were to grant world-read rights on the file (mode rw-r--r--) but not change the directory permissions it'd make no difference. Nobody could see the file in order to read it, because they don't have the rights to list the directory.

If you instead set rwx-r-xr-x on the directory, setting it so people can list and traverse the directory but not changing the file permissions, people could list the file but could not read it because they'd have no access to the file.

You need to set both permissions for people to actually be able to view the file.

Same thing in Pg. You need both schema USAGE rights and object rights to perform an action on an object, like SELECT from a table.

(The analogy falls down a bit in that PostgreSQL doesn't have row-level security yet, so the user can still "see" that the table exists in the schema by SELECTing from pg_class directly. They can't interact with it in any way, though, so it's just the "list" part that isn't quite the same.)

Eclipse for PHP Developers Package

Looking for the Eclipse for PHP Developers Package?

Due to lack of a package maintainer for the Indigo release there will be no PHP (PDT) package. If you would like to install PDT into your Eclipse installtion you can do so by using the Install New Software feature from the Help Menu and installing the PHP Development Tools (PDT) SDK Feature from the Eclipse Indigo Repo >> http://download.eclipse.org/releases/indigo

Text grabbed from page: http://www.eclipse.org/downloads/php_package.php

Probably the only choice is to read it on the client side and transfer it manually to the server (GET/POST/AJAX). Regards Artur

Could also use a template string:

const num = 123456
`${num}`.length // 6

Just for the sake of completeness, since I noticed no one suggested this simple approach:

>>> print("%.0f%%" % (100 * 1.0/3))
33%

Details:

• %.0f stands for "print a float with 0 decimal places", so %.2f would print 33.33
• %% prints a literal %. A bit cleaner than your original +'%'
• 1.0 instead of 1 takes care of coercing the division to float, so no more 0.0

If you don't mind using OFFSET(), which is a volatile function that recalculates everytime a cell is changed, then this is a good solution that is both dynamic and reusable:

=OFFSET($COL:$COL, ROW(), 1, 1048576 - ROW(), 1)

where $COL is the letter of the column you are going to operate upon, and ROW() is the row function that dynamically selects the same row as the cell containing this formula. You could also replace the ROW() function with a static number ($ROW).

=OFFSET($COL:$COL, $ROW, 1, 1048576 - $ROW, 1)

You could further clean up the formula by defining a named constant for the 1048576 as 'maxRows'. This can be done in the 'Define Name' menu of the Formulas tab.

=OFFSET($COL:$COL, $ROW, 1, maxRows - $ROW, 1)

A quick example: to Sum from C6 to the end of column C, you could do:

=SUM(OFFSET(C:C, 6, 1, maxRows - 6, 1))

or =SUM(OFFSET(C:C, ROW(), 1, maxRows - ROW(),1))

I faced with the same issue. I just added credentials config:

aws_access_key_id = your_aws_access_key_id
aws_secret_access_key = your_aws_secret_access_key

into "~/.aws/credentials" + restart terminal for default profile.

In the case of multi profiles --profile arg needs to be added:

aws s3 sync ./localDir s3://bucketName --profile=${PROFILE_NAME}

where PROFILE_NAME:

.bash_profile ( or .bashrc) -> export PROFILE_NAME="yourProfileName"

More info about how to config credentials and multi profiles can be found here

Simply, @Id: This annotation specifies the primary key of the entity. 

@GeneratedValue: This annotation is used to specify the primary key generation strategy to use. i.e Instructs database to generate a value for this field automatically. If the strategy is not specified by default AUTO will be used. 

GenerationType enum defines four strategies: 
1. Generation Type . TABLE, 
2. Generation Type. SEQUENCE,
3. Generation Type. IDENTITY   
4. Generation Type. AUTO

GenerationType.SEQUENCE

With this strategy, underlying persistence provider must use a database sequence to get the next unique primary key for the entities. 

GenerationType.TABLE

With this strategy, underlying persistence provider must use a database table to generate/keep the next unique primary key for the entities. 

GenerationType.IDENTITY
This GenerationType indicates that the persistence provider must assign primary keys for the entity using a database identity column. IDENTITY column is typically used in SQL Server. This special type column is populated internally by the table itself without using a separate sequence. If underlying database doesn't support IDENTITY column or some similar variant then the persistence provider can choose an alternative appropriate strategy. In this examples we are using H2 database which doesn't support IDENTITY column.

GenerationType.AUTO
This GenerationType indicates that the persistence provider should automatically pick an appropriate strategy for the particular database. This is the default GenerationType, i.e. if we just use @GeneratedValue annotation then this value of GenerationType will be used.

There are a lot of answer above which will definitely help you but (after 2 days of afford and research on adb memory tools) I think i can help with my opinion too.

As Hackbod says : Thus if you were to take all of the physical RAM actually mapped in to each process, and add up all of the processes, you would probably end up with a number much greater than the actual total RAM. so there is no way you can get exact amount of memory per process.

But you can get close to it by some logic..and I will tell how..

There are some API like android.os.Debug.MemoryInfo and ActivityManager.getMemoryInfo() mentioned above which you already might have being read about and used but I will talk about other way

So firstly you need to be a root user to get it work. Get into console with root privilege by executing su in process and get its output and input stream. Then pass id\n (enter) in ouputstream and write it to process output, If will get an inputstream containing uid=0, you are root user.

Now here is the logic which you will use in above process

When you get ouputstream of process pass you command (procrank, dumpsys meminfo etc...) with \n instead of id and get its inputstream and read, store the stream in bytes[ ] ,char[ ] etc.. use raw data..and you are done!!!!!

permission :

<uses-permission android:name="android.permission.FACTORY_TEST"/>

Check if you are root user :

// su command to get root access
Process process = Runtime.getRuntime().exec("su");         
DataOutputStream dataOutputStream = 
                           new DataOutputStream(process.getOutputStream());
DataInputStream dataInputStream = 
                           new DataInputStream(process.getInputStream());
if (dataInputStream != null && dataOutputStream != null) {
   // write id to console with enter
   dataOutputStream.writeBytes("id\n");                   
   dataOutputStream.flush();
   String Uid = dataInputStream.readLine();
   // read output and check if uid is there
   if (Uid.contains("uid=0")) {                           
      // you are root user
   } 
}

Execute your command with su

Process process = Runtime.getRuntime().exec("su");         
DataOutputStream dataOutputStream = 
                           new DataOutputStream(process.getOutputStream());
if (dataOutputStream != null) {
 // adb command
 dataOutputStream.writeBytes("procrank\n");             
 dataOutputStream.flush();
 BufferedInputStream bufferedInputStream = 
                     new BufferedInputStream(process.getInputStream());
 // this is important as it takes times to return to next line so wait
 // else you with get empty bytes in buffered stream 
 try {
       Thread.sleep(10000);
 } catch (InterruptedException e) {                     
       e.printStackTrace();
 }
 // read buffered stream into byte,char etc.
 byte[] bff = new byte[bufferedInputStream.available()];
 bufferedInputStream.read(bff);
 bufferedInputStream.close();
 }
}

logcat :

You get a raw data in a single string from console instead of in some instance from any API,which is complex to store as you will need to separate it manually.

This is just a try, please suggest me if I missed something

Best solution: Don't use globals

>>> test1 = 0
>>> def test_func(x):
        return x + 1

>>> test1 = test_func(test1)
>>> test1
1

Let me help in updating the answers here since new users will find it useful. I believe the aim is to delete the database itself and recreate it using EF Code First approach. 1.Open your project in Visual Studio using the ".sln" extention. 2.Select Server Explorer( it is oftentimes on the left) 3.Select SQL Server Object Explorer. 4.The database you want to delete would be listed under any of the localDB. Right-Click it and select delete.

I think the best way, is to use a Propper Form and to use jQuery.serializeArray.

<!-- a form with any type of input -->
<form class="a-form">
    <select name="field[something]">...</select>
    <input type="checkbox" name="field[somethingelse]" ... />
    <input type="radio" name="field[somethingelse2]" ... />
    <input type="text" name="field[somethingelse3]" ... />
</form>

<!-- sample ajax call -->
<script>
$(document).ready(function(){
    $.ajax({
        url: 'submit.php',
        type: 'post',
        data: $('form.a-form').serializeArray(),
        success: function(response){
            ...
        }
    });
});
</script>

The Values will be available in PHP as $_POST['field'][INDEX].

I had to do recently something similar, I used this snippet:

const getNode = () =>
  for (let el = this.$el; el && el.parentNode; el = el.parentNode){
    if (/* insert your condition here */) return el;
  }
  return null
})

The function will returns the element that fulfills your condition. It was a CSS class on the element that I was looking for. If there isn't such element then it will return null

In case somebody would look for multiple elements it only returns closest parent to the element that you provided.

My example was:

if (el.classList?.contains('o-modal')) return el;

I used it in a vue component (this.$el) change that to your document.getElementById function and you're good to go. Hope it will be useful for some people ??

I found it very useful, since the Exceptions are not documented, to list all exceptions to the screen for this package. Here is the code I used to do it:

import botocore.exceptions
def listexns(mod):
    #module = __import__(mod)
    exns = []
    for name in botocore.exceptions.__dict__:
        if (isinstance(botocore.exceptions.__dict__[name], Exception) or
            name.endswith('Error')):
            exns.append(name)
    for name in exns:
        print('%s.%s is an exception type' % (str(mod), name))
    return

if __name__ == '__main__':
    import sys
    if len(sys.argv) <= 1:
        print('Give me a module name on the $PYTHONPATH!')
    print('Looking for exception types in module: %s' % sys.argv[1])
    listexns(sys.argv[1])

Which results in:

There is no semicolon at the end of that instruction causing the error.

EDIT

Like RiverC pointed out, there is no semicolon at the end of the previous line!

require ("scripts/connect.php") 

EDIT

It seems you have no-semicolons whatsoever.

http://php.net/manual/en/language.basic-syntax.instruction-separation.php

As in C or Perl, PHP requires instructions to be terminated with a semicolon at the end of each statement.

If you want to enable unblur, you cannot just add the blur CSS to the body, you need to blur each visible child one level directly under the body and then remove the CSS to unblur. The reason is because of the "Cascade" in CSS, you cannot undo the cascading of the CSS blur effect for a child of the body. Also, to blur the body's background image you need to use the pseudo element :before

You're pretty much right about cout and cin. They are objects (not functions) defined inside the std namespace. Here are their declarations as defined by the C++ standard:

Header <iostream> synopsis

#include <ios>
#include <streambuf>
#include <istream>
#include <ostream>

namespace std {
  extern istream cin;
  extern ostream cout;
  extern ostream cerr;
  extern ostream clog;

  extern wistream wcin;
  extern wostream wcout;
  extern wostream wcerr;
  extern wostream wclog;
}

:: is known as the scope resolution operator. The names cout and cin are defined within std, so we have to qualify their names with std::.

Classes behave a little like namespaces in that the names declared inside the class belong to the class. For example:

class foo
{
  public:
    foo();
    void bar();
};

The constructor named foo is a member of the class named foo. They have the same name because its the constructor. The function bar is also a member of foo.

Because they are members of foo, when referring to them from outside the class, we have to qualify their names. After all, they belong to that class. So if you're going to define the constructor and bar outside the class, you need to do it like so:

foo::foo()
{
  // Implement the constructor
}

void foo::bar()
{
  // Implement bar
}

This is because they are being defined outside the class. If you had not put the foo:: qualification on the names, you would be defining some new functions in the global scope, rather than as members of foo. For example, this is entirely different bar:

void bar()
{
  // Implement different bar
}

It's allowed to have the same name as the function in the foo class because it's in a different scope. This bar is in the global scope, whereas the other bar belonged to the foo class.

In C, memcpy is only foolishly risky. As long as you get all three parameters exactly right, none of the struct members are pointers (or, you explicitly intend to do a shallow copy) and there aren't large alignment gaps in the struct that memcpy is going to waste time looping through (or performance never matters), then by all means, memcpy. You gain nothing except code that is harder to read, fragile to future changes and has to be hand-verified in code reviews (because the compiler can't), but hey yeah sure why not.

In C++, we advance to the ludicrously risky. You may have members of types which are not safely memcpyable, like std::string, which will cause your receiving struct to become a dangerous weapon, randomly corrupting memory whenever used. You may get surprises involving virtual functions when emulating slice-copies. The optimizer, which can do wondrous things for you because it has a guarantee of full type knowledge when it compiles =, can do nothing for your memcpy call.

In C++ there's a rule of thumb - if you see memcpy or memset, something's wrong. There are rare cases when this is not true, but they do not involve structs. You use memcpy when, and only when, you have reason to blindly copy bytes.

Assignment on the other hand is simple to read, checks correctness at compile time and then intelligently moves values at runtime. There is no downside.

Have you renamed your project/main class (e.g. through refactoring) ? If yes your Launch Configuration might be set up incorrectly (e.g. refering to the old main class or configuration). Even though the project name appears in the 'export runnable jar' dialog, a closer inspection might reveal an unmatched main class name.

Go to 'Properties->Run/Debug Settings' of your project and make sure your Launch Configuration (the same used to export runnable jar) is set to the right name of project AND your main class is set to name.space.of.your.project/YouMainClass.

After importing the scripting runtime as described above you have to make some slighty modification to get it working in Excel 2010 (my version). Into the following code I've also add the code used to the user to pick a file.

Dim intChoice As Integer
Dim strPath As String

' Select one file
Application.FileDialog(msoFileDialogOpen).AllowMultiSelect = False

' Show the selection window
intChoice = Application.FileDialog(msoFileDialogOpen).Show

' Get back the user option
If intChoice <> 0 Then
    strPath = Application.FileDialog(msoFileDialogOpen).SelectedItems(1)
Else
    Exit Sub
End If

Dim FSO As New Scripting.FileSystemObject
Dim fsoStream As Scripting.TextStream
Dim strLine As String

Set fsoStream = FSO.OpenTextFile(strPath)

Do Until fsoStream.AtEndOfStream = True
    strLine = fsoStream.ReadLine
    ' ... do your work ...
Loop

fsoStream.Close
Set FSO = Nothing

Hope it help!

You can cast a method group into a delegate.

The delegate signature selects 1 method out of the group.

This example picks the ToString() overload which takes a string parameter:

Func<string,string> fn = 123.ToString;
Console.WriteLine(fn("00000000"));

This example picks the ToString() overload which takes no parameters:

Func<string> fn = 123.ToString;
Console.WriteLine(fn());

My simple fix to stop it putting speech marks around numeric values...

while($r = mysql_fetch_assoc($rs)){
    while($elm=each($r))
    {
        if(is_numeric($r[$elm["key"]])){
                    $r[$elm["key"]]=intval($r[$elm["key"]]);
        }
    }
    $rows[] = $r;
}   

The solution that work for me is the following:

$("#spanId").text("text to show");

I use MVC 3. An example of email address property in one of my classes is:

[Display(Name = "Email address")]
[Required(ErrorMessage = "The email address is required")]
[Email(ErrorMessage = "The email address is not valid")]
public string Email { get; set; }

Remove the Required if the input is optional. No need for regular expressions although I have one which covers all of the options within an email address up to RFC 2822 level (it's very long).

I recommend using a cache-buster in the wsdl url.

In our apps we use a SVN Revision id in the wsdl url so the client immediately knows of changing structures. This works on our app because, everytime we change the server-side, we also need to adjust the client accordingly.

$client = new SoapClient('http://somewhere.com/?wsdl&rev=$Revision$');

This requires svn to be configured properly. Not on all repositories this is enabled by default.

In case you are not responsible for both components (server,client) or you don't use SVN you may find another indicator which can be utilised as a cache-buster in your wsdl url.

something like this:

f = open('data.txt', 'r')  
for line in f:  
   line =  line.split(';')  
   product = Product()  
   product.name = line[2] + '(' + line[1] + ')'  
   product.description = line[4]  
   product.price = '' #data is missing from file  
   product.save()  

f.close()  

Modify your filter like this:

filter isNumeric {
    [Helpers]::IsNumeric($_)
}

function uses the $input variable to contain pipeline information whereas the filter uses the special variable $_ that contains the current pipeline object.

Edit:

For a powershell syntax way you can use just a filter (w/o add-type):

filter isNumeric() {
    return $_ -is [byte]  -or $_ -is [int16]  -or $_ -is [int32]  -or $_ -is [int64]  `
       -or $_ -is [sbyte] -or $_ -is [uint16] -or $_ -is [uint32] -or $_ -is [uint64] `
       -or $_ -is [float] -or $_ -is [double] -or $_ -is [decimal]
}

str.startswith allows you to supply a tuple of strings to test for:

if link.lower().startswith(("js", "catalog", "script", "katalog")):

From the docs:

str.startswith(prefix[, start[, end]])

Return True if string starts with the prefix, otherwise return False. prefix can also be a tuple of prefixes to look for.

Below is a demonstration:

>>> "abcde".startswith(("xyz", "abc"))
True
>>> prefixes = ["xyz", "abc"]
>>> "abcde".startswith(tuple(prefixes)) # You must use a tuple though
True
>>>

1: I have downloaded the mysql-connector-java-5.1.24-bin.jar

Okay.

2: I have created a lib folder in my project and put the jar in there.

Wrong. You need to drop JAR in /WEB-INF/lib folder. You don't need to create any additional folders.

3: properties of project->build path->add JAR and selected the JAR above.

Unnecessary. Undo it all to avoid possible conflicts.

4: I still get java.sql.SQLException: No suitable driver found for jdbc:mysql//localhost:3306/mysql

This exception can have 2 causes:

1. JDBC driver is not in runtime classpath. This is to be solved by doing 2) the right way.

2. JDBC URL is not recognized by any of the loaded JDBC drivers. Indeed, the JDBC URL is wrong, there should as per the MySQL JDBC driver documentation be another colon between the scheme and the host.

   jdbc:mysql://localhost:3306/mysql
   

Simply restarting Visual Studio worked for me.

Ensure you have enabled mod_rewrite (I hadn't).
To enable:

sudo a2enmod rewrite  

Also, replace AllowOverride None by AllowOverride All

sudo gedit /etc/apache2/sites-available/default  

Finaly...

sudo /etc/init.d/apache2 restart  

My .htaccess is

RewriteEngine on  
RewriteCond $1 !^(index\.php|[assets/css/js/img]|robots\.txt)  
RewriteRule ^(.*)$ index.php/$1 [L]  

If double-clicking on it brings up WinRAR, you need to change the program you are running it with. You can right-click on it and click "Open with". Java should be listed in there.

However, you must first upgrade your Java version to be compatible with that JAR.

I recently got this error. I had compiled the binary with -O3. Google told me that this means "illegal opcode", which seemed fishy to me. I then turned off all optimizations and reran. Now the error transformed to a segfault. Hence by setting -g and running valgrind I tracked the source down and fixed it. Reenabling all optimizations showed no further appearances of illegal instruction 4.

Apparently, optimizing wrong code can yield weird results.

I would go with netcat too , but since you can't use it , here is an alternative : netcat :). You can find netcat implemented in three languages ( python/ruby/perl ) . All you need to do is install the interpreters for the language you choose . Surely , that won't be viewed as a hacking tool .

Here are the links :

The answers by Bomber and Jakub (Thanks!) are correct and work for me in different situations.

For a quick glance at what was in the commit, I use

git show <replace this with your commit-id>

But I like to view a graphical Diff when studying something in detail and have set up a P4diff as my git diff and then use

git diff <replace this with your commit-id>^!
