Nice job! I've been having the exact same problem. Adding and removing the Session module worked perfectly for me too. It didn't however bring back by HttpContext.Current.User so I tried your little trick with the FormsAuth module and sure enough, that did it.

<remove name="FormsAuthentication" />
<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule"/>

If you select the log entry to which you want to revert to then you can click on "Reset to this commit". Only use this option if you didn't push the reverse commit changes. If you're worried about losing the changes then you can use the soft mode which will leave a set of uncommitted changes (what you just changed). Using the mixed resets the working copy but keeps those changes, and a hard will just get rid of the changes entirely. Here's some screenshots:

IMO, an omission. But I think there is good reason not to include a Tree structure in the STL. There is a lot of logic in maintaining a tree, which is best written as member functions into the base TreeNode object. When TreeNode is wrapped up in an STL header, it just gets messier.

For example:

template <typename T>
struct TreeNode
{
  T* DATA ; // data of type T to be stored at this TreeNode

  vector< TreeNode<T>* > children ;

  // insertion logic for if an insert is asked of me.
  // may append to children, or may pass off to one of the child nodes
  void insert( T* newData ) ;

} ;

template <typename T>
struct Tree
{
  TreeNode<T>* root;

  // TREE LEVEL functions
  void clear() { delete root ; root=0; }

  void insert( T* data ) { if(root)root->insert(data); } 
} ;

Here is what worked for me.

Install the userspace USB programming library development files

sudo apt-get install libusb-1.0-0-dev
sudo updatedb && locate libusb.h

The path should appear as (or similar)

/usr/include/libusb-1.0/libusb.h

Include the header to your C code

#include <libusb-1.0/libusb.h>

Compile your C file

gcc -o example example.c -lusb-1.0

If you're trying to put a button in a rounded-rectangle border, you should check out msdn's example. I found this by googling for images of the problem (instead of text). Their bulky outer rectangle is (thankfully) easy to remove.

Note that you will have to redefine the button's behavior (since you've changed the ControlTemplate). That is, you will need to define the button's behavior when clicked using a Trigger tag (Property="IsPressed" Value="true") in the ControlTemplate.Triggers tag. Hope this saves someone else the time I lost :)

I would like to give another example in which multiple (3) joins are used.

 DataClasses1DataContext ctx = new DataClasses1DataContext();

        var Owners = ctx.OwnerMasters;
        var Category = ctx.CategoryMasters;
        var Status = ctx.StatusMasters;
        var Tasks = ctx.TaskMasters;

        var xyz = from t in Tasks
                  join c in Category
                  on t.TaskCategory equals c.CategoryID
                  join s in Status
                  on t.TaskStatus equals s.StatusID
                  join o in Owners
                  on t.TaskOwner equals o.OwnerID
                  select new
                  {
                      t.TaskID,
                      t.TaskShortDescription,
                      c.CategoryName,
                      s.StatusName,
                      o.OwnerName
                  };

I solved my problem with code below.

display: table-caption;

Do not simplify the code to avoid "linq translation error": The test consist between a date with time at 0:0:0 and the same date with time at 23:59:59

        iFilter.MyDate1 = DateTime.Today;  // or DateTime.MinValue

        // GET 
        var tempQuery = ctx.MyTable.AsQueryable();

        if (iFilter.MyDate1 != DateTime.MinValue)
        {
            TimeSpan temp24h = new TimeSpan(23,59,59);
            DateTime tempEndMyDate1 = iFilter.MyDate1.Add(temp24h);

            // DO not change the code below, you need 2 date variables...
            tempQuery = tempQuery.Where(w => w.MyDate2 >= iFilter.MyDate1
                                          && w.MyDate2 <= tempEndMyDate1);
        }

        List<MyTable> returnObject = tempQuery.ToList();

To remove this Dex issue just implement one dependency. This issue occur when we are using multiple different service from the same server. Suppose we are using ads and Firestore in a project and both have a repository maven. so we need to call different data with on repository we need dex dependency to implement. The new update Dependency:-

 implementation 'com.android.support:multidex:1.0.3'

I'm sure it will resolve your issue permanent

How about

Select I.Fee
From Item I
WHERE  (days(GETDATE()) - days(I.DateCreated) < 365)

In addition to ways already mentioned.. can use 'viewitems', 'viewkeys', 'viewvalues'

>>> d = {320: 1, 321: 0, 322: 3}
>>> list(d.viewitems())
[(320, 1), (321, 0), (322, 3)]
>>> list(d.viewkeys())
[320, 321, 322]
>>> list(d.viewvalues())
[1, 0, 3]

Or

>>> list(d.iteritems())
[(320, 1), (321, 0), (322, 3)]
>>> list(d.iterkeys())
[320, 321, 322]
>>> list(d.itervalues())
[1, 0, 3]

or using itemgetter

>>> from operator import itemgetter
>>> map(itemgetter(0), dd.items())     ####  for keys
['323', '332']
>>> map(itemgetter(1), dd.items())     ####  for values
['3323', 232]

The issue is related to the DockerFile creation procedure.

In order to work, open cmd, cd to the directory of interest and type:

abc>DockerFile

This will create a file called DockerFile inside your folder.

Now type:

notepad DockerFile 

This will open the DockerFile file in notepad and you will have to copy/paste the standard code provided.

Save the file and now, finally, build your image with Docker typing:

docker build -t docker-whale . 

This is working for me and I hope it helps others

BTW, Yandex Metrica also uses IDFA.

./Pods/YandexMobileMetrica/libYandexMobileMetrica.a

They say on their GitHub page that

"Starting from version 1.6.0 Yandex AppMetrica became also a tracking instrument and uses Apple idfa to attribute installs. Because of that during submitting your application to the AppStore you will be prompted with three checkboxes to state your intentions for idfa usage. As Yandex AppMetrica uses idfa for attributing app installations you need to select Attribute this app installation to a previously served advertisement."

So, I will try to select this checkbox and send my app without actually no any ads in it.

There are many GOOD reasons to use @import.

One powerful reason for using @import is to do cross-browser design. Imported sheets, in general, are hidden from many older browsers, which allows you to apply specific formatting for very old browsers like Netscape 4 or older series, Internet Explorer 5.2 for Mac, Opera 6 and older, and IE 3 and 4 for PC.

To do this, in your base.css file you could have the following:

@import 'newerbrowsers.css';

body {
  font-size:13px;
}

In your imported custom sheet (newerbrowsers.css) simply apply the newer cascading style:

html body {
  font-size:1em;
}

Using "em" units is superior to "px" units as it allows both the fonts and design to stretch based on user settings, where as older browsers do better with pixel-based (which are rigid and cannot be changed in browser user settings). The imported sheet would not be seen by most older browsers.

You may so, who cares! Try going to some larger antiquated government or corporate systems and you will still see those older browsers used. But its really just good design, because the browser you love today will also someday be antiquated and outdated as well. And using CSS in a limited way means you now have an even larger and growing group of user-agents that dont work well with you site.

Using @import your cross-browser web site compatibility will now reach 99.9% saturation simply because so many older browser wont read the imported sheets. It guarantees you apply a basic simple font set for their html, but more advanced CSS is used by newer agents. This allows content to be accessible for older agents without compromising rich visual displays needed in newer desktop browsers.

Remember, modern browsers cache HTML structures and CSS extremely well after the first call to a web site. Multiple calls to the server is not the bottleneck it once was.

Megabytes and megabytes of Javascript API's and JSON uploaded to smart devices and poorly designed HTML markup that is not consistent between pages is the main driver of slow rendering today. Youre average Google news page is over 6 megabytes of ECMAScript just to render a tiny bit of text! LOL

A few kilobytes of cached CSS and consistent clean HTML with smaller javascript footprints will render in a user-agent in lightning speed simply because the browser caches both consistent DOM markup and CSS, unless you choose to manipulate and change that via javascript circus tricks.

I use this

def cleaned( aFile ):
    for line in aFile:
        yield line.strip()

Then I can do things like this.

lines = list( cleaned( open("file","r") ) )

Or, I can extend cleaned with extra functions to, for example, drop blank lines or skip comment lines or whatever.

Emulation is a multi-faceted area. Here are the basic ideas and functional components. I'm going to break it into pieces and then fill in the details via edits. Many of the things I'm going to describe will require knowledge of the inner workings of processors -- assembly knowledge is necessary. If I'm a bit too vague on certain things, please ask questions so I can continue to improve this answer.

Basic idea:

Emulation works by handling the behavior of the processor and the individual components. You build each individual piece of the system and then connect the pieces much like wires do in hardware.

Processor emulation:

There are three ways of handling processor emulation:

• Interpretation
• Dynamic recompilation
• Static recompilation

With all of these paths, you have the same overall goal: execute a piece of code to modify processor state and interact with 'hardware'. Processor state is a conglomeration of the processor registers, interrupt handlers, etc for a given processor target. For the 6502, you'd have a number of 8-bit integers representing registers: A, X, Y, P, and S; you'd also have a 16-bit PC register.

With interpretation, you start at the IP (instruction pointer -- also called PC, program counter) and read the instruction from memory. Your code parses this instruction and uses this information to alter processor state as specified by your processor. The core problem with interpretation is that it's very slow; each time you handle a given instruction, you have to decode it and perform the requisite operation.

With dynamic recompilation, you iterate over the code much like interpretation, but instead of just executing opcodes, you build up a list of operations. Once you reach a branch instruction, you compile this list of operations to machine code for your host platform, then you cache this compiled code and execute it. Then when you hit a given instruction group again, you only have to execute the code from the cache. (BTW, most people don't actually make a list of instructions but compile them to machine code on the fly -- this makes it more difficult to optimize, but that's out of the scope of this answer, unless enough people are interested)

With static recompilation, you do the same as in dynamic recompilation, but you follow branches. You end up building a chunk of code that represents all of the code in the program, which can then be executed with no further interference. This would be a great mechanism if it weren't for the following problems:

• Code that isn't in the program to begin with (e.g. compressed, encrypted, generated/modified at runtime, etc) won't be recompiled, so it won't run
• It's been proven that finding all the code in a given binary is equivalent to the Halting problem

These combine to make static recompilation completely infeasible in 99% of cases. For more information, Michael Steil has done some great research into static recompilation -- the best I've seen.

The other side to processor emulation is the way in which you interact with hardware. This really has two sides:

• Processor timing
• Interrupt handling

Processor timing:

Certain platforms -- especially older consoles like the NES, SNES, etc -- require your emulator to have strict timing to be completely compatible. With the NES, you have the PPU (pixel processing unit) which requires that the CPU put pixels into its memory at precise moments. If you use interpretation, you can easily count cycles and emulate proper timing; with dynamic/static recompilation, things are a /lot/ more complex.

Interrupt handling:

Interrupts are the primary mechanism that the CPU communicates with hardware. Generally, your hardware components will tell the CPU what interrupts it cares about. This is pretty straightforward -- when your code throws a given interrupt, you look at the interrupt handler table and call the proper callback.

Hardware emulation:

There are two sides to emulating a given hardware device:

• Emulating the functionality of the device
• Emulating the actual device interfaces

Take the case of a hard-drive. The functionality is emulated by creating the backing storage, read/write/format routines, etc. This part is generally very straightforward.

The actual interface of the device is a bit more complex. This is generally some combination of memory mapped registers (e.g. parts of memory that the device watches for changes to do signaling) and interrupts. For a hard-drive, you may have a memory mapped area where you place read commands, writes, etc, then read this data back.

I'd go into more detail, but there are a million ways you can go with it. If you have any specific questions here, feel free to ask and I'll add the info.

Resources:

I think I've given a pretty good intro here, but there are a ton of additional areas. I'm more than happy to help with any questions; I've been very vague in most of this simply due to the immense complexity.

Obligatory Wikipedia links:

• Emulator
• Dynamic recompilation

General emulation resources:

• Zophar -- This is where I got my start with emulation, first downloading emulators and eventually plundering their immense archives of documentation. This is the absolute best resource you can possibly have.
• NGEmu -- Not many direct resources, but their forums are unbeatable.
• RomHacking.net -- The documents section contains resources regarding machine architecture for popular consoles

Emulator projects to reference:

• IronBabel -- This is an emulation platform for .NET, written in Nemerle and recompiles code to C# on the fly. Disclaimer: This is my project, so pardon the shameless plug.
• BSnes -- An awesome SNES emulator with the goal of cycle-perfect accuracy.
• MAME -- The arcade emulator. Great reference.
• 6502asm.com -- This is a JavaScript 6502 emulator with a cool little forum.
• dynarec'd 6502asm -- This is a little hack I did over a day or two. I took the existing emulator from 6502asm.com and changed it to dynamically recompile the code to JavaScript for massive speed increases.

Processor recompilation references:

• The research into static recompilation done by Michael Steil (referenced above) culminated in this paper and you can find source and such here.

Addendum:

It's been well over a year since this answer was submitted and with all the attention it's been getting, I figured it's time to update some things.

Perhaps the most exciting thing in emulation right now is libcpu, started by the aforementioned Michael Steil. It's a library intended to support a large number of CPU cores, which use LLVM for recompilation (static and dynamic!). It's got huge potential, and I think it'll do great things for emulation.

emu-docs has also been brought to my attention, which houses a great repository of system documentation, which is very useful for emulation purposes. I haven't spent much time there, but it looks like they have a lot of great resources.

I'm glad this post has been helpful, and I'm hoping I can get off my arse and finish up my book on the subject by the end of the year/early next year.

just wanted to leave my .scss example here, I think its kinda best practice, especially I think if you do customization its nice to set the width only once! It is not clever to apply it everywhere, you will increase the human factor exponentially.

Im looking forward for your feedback!

// Set your parameters
$widthSmall: 768px;
$widthMedium: 992px;

// Prepare your "function"
@mixin in-between {
     @media (min-width:$widthSmall) and (max-width:$widthMedium) {
        @content;
     }
}


// Apply your "function"
main {
   @include in-between {
      //Do something between two media queries
      padding-bottom: 20px;
   }
}

Easy, simple way:

const select = document.getElementById('selectID');
const selectedOption = [...select.options].find(option => option.selected).text;

You can create swap space using the following steps Here we are creating swap at /home/

1. dd if=/dev/zero of=/home/swapfile1 bs=1024 count=8388608
   Here count is kilobyte count of swap space

2. mkswap /home/swapfile1

3. vi /etc/fstab
   make entry :
   /home/swapfile1 swap swap defaults 0 0

4. run:
   swapon -a

Just use
<Table cellpadding="10" ..> ... </Table>
Don't use px.Works in MS-Outlook.

It's a better idea to put your configuration variables in a configuration file.

In your case, I would suggest putting your variables in config/mail.php like:

'imap_hostname' => env('IMAP_HOSTNAME_TEST', 'imap.gmail.com')

And refer to them by

config('mail.imap_hostname')

It first tries to get the configuration variable value in the .env file and if it couldn't find the variable value in the .env file, it will get the variable value from file config/mail.php.

You don't really need it today, because the current standard makes it optional -- and every useful browser currently assumes that a style sheet is CSS, even in versions of HTML that considered the attribute "required".

With HTML being a "living standard" now, though -- and thus subject to change -- you can only guarantee so much. And there's no new DTD that you can point to and say the page was written for that version of HTML, and no reliable way even to say "HTML as of such-and-such a date". For forward-compatibility reasons, in my opinion, you should specify the type.

I do it in this way for openxlsx using following function

mywritexlsx<-function(fname="temp.xlsx",sheetname="Sheet1",data,
                  startCol = 1, startRow = 1, colNames = TRUE, rowNames = FALSE)
{
  if(! file.exists(fname))
    wb = createWorkbook()
  else
   wb <- loadWorkbook(file =fname)
  sheet = addWorksheet(wb, sheetname)

  writeData(wb,sheet,data,startCol = startCol, startRow = startRow, 
          colNames = colNames, rowNames = rowNames)
  saveWorkbook(wb, fname,overwrite = TRUE)
}

I need to do "fluid" rectangles not squares.... so THANKS to JOPL .... didn't take but a minute....

#map_container {
     position: relative;
     width: 100%;
     padding-bottom: 75%;
}


#map {
    position:absolute;
    width:100%;
    height:100%;
}

It depends on the problem.

Adjacency Matrix

• Uses O(n^2) memory
• It is fast to lookup and check for presence or absence of a specific edge
  between any two nodes O(1)
• It is slow to iterate over all edges
• It is slow to add/delete a node; a complex operation O(n^2)
• It is fast to add a new edge O(1)

Adjacency List

• Memory usage depends on the number of edges (not number of nodes),
  which might save a lot of memory if the adjacency matrix is sparse
• Finding the presence or absence of specific edge between any two nodes
  is slightly slower than with the matrix O(k); where k is the number of neighbors nodes
• It is fast to iterate over all edges because you can access any node neighbors directly
• It is fast to add/delete a node; easier than the matrix representation
• It fast to add a new edge O(1)

If you are sure you want to remove all commit history, simply delete the .git directory in your project root (note that it's hidden). Then initialize a new repository in the same folder and link it to the GitHub repository:

git init
git remote add origin [email protected]:user/repo

now commit your current version of code

git add *
git commit -am 'message'

and finally force the update to GitHub:

git push -f origin master

However, I suggest backing up the history (the .git folder in the repository) before taking these steps!

The value of event handler attributes such as onclick should just be JavaScript, without any "javascript:" prefix. The javascript: pseudo-protocol is used in a URL, for example:

<a href="javascript:func(this)">here</a>

You should use the onclick="func(this)" form in preference to this though. Also note that in my example above using the javascript: pseudo-protocol "this" will refer to the window object rather than the <a> element.

I have stopped on the script like below (as I have only one non-clustered unique index in this table):

declare @table_name nvarchar(256)  
declare @col_name nvarchar(256)  
declare @Command  nvarchar(1000)  

set @table_name = N'users'
set @col_name = N'login'

select @Command = 'ALTER TABLE ' + @table_name + ' drop constraint ' + d.name
    from sys.tables t join sys.indexes d on d.object_id = t.object_id  
    where t.name = @table_name and d.type=2 and d.is_unique=1

--print @Command

execute (@Command)

Has anyone comments if this solution is acceptable? Any pros and cons?

Thanks.

When you're working with strings in PHP you'll need to pay special attention to the formation, using " or '

$string = 'Hello, world!';
$string = "Hello, world!";

Both of these are valid, the following is not:

$string = "Hello, world';

You must also note that ' inside of a literal started with " will not end the string, and vice versa. So when you have a string which contains ', it is generally best practice to use double quotation marks.

$string = "It's ok here";

Escaping the string is also an option

$string = 'It\'s ok here too';

More information on this can be found within the documentation

To remove a timezone (tzinfo) from a datetime object:

# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)

If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.

# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)

Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime object to insert into the database. The solution is to convert your datetime.datetime object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime objects where one is timezone aware and another is timezone naive.

##############################################################################
# MySQL example! where MySQL doesn't support timezones with its DATETIME type!
##############################################################################

arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

arrowDt = arrowObj.to("utc").datetime

# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)

# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()

# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3

# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True

map.has(key) is the latest ECMAScript 2015 way of checking the existance of a key in a map. Refer to this for complete details.

Had this problem where the Deployment was in a sub-chart and the values controlling it were in the parent chart's values file. This is what we used to trigger restart:

spec:
  template:
    metadata:
      annotations:
        checksum/config: {{ tpl (toYaml .Values) . | sha256sum }}

Obviously this will trigger restart on any value change but it works for our situation. What was originally in the child chart would only work if the config.yaml in the child chart itself changed:

    checksum/config: {{ include (print $.Template.BasePath "/config.yaml") . | sha256sum }}

From the C++ FQA Lite:

[16.4] Why should I use new instead of trustworthy old malloc()?

FAQ: new/delete call the constructor/destructor; new is type safe, malloc is not; new can be overridden by a class.

FQA: The virtues of new mentioned by the FAQ are not virtues, because constructors, destructors, and operator overloading are garbage (see what happens when you have no garbage collection?), and the type safety issue is really tiny here (normally you have to cast the void* returned by malloc to the right pointer type to assign it to a typed pointer variable, which may be annoying, but far from "unsafe").

Oh, and using trustworthy old malloc makes it possible to use the equally trustworthy & old realloc. Too bad we don't have a shiny new operator renew or something.

Still, new is not bad enough to justify a deviation from the common style used throughout a language, even when the language is C++. In particular, classes with non-trivial constructors will misbehave in fatal ways if you simply malloc the objects. So why not use new throughout the code? People rarely overload operator new, so it probably won't get in your way too much. And if they do overload new, you can always ask them to stop.

Sorry, I just couldn't resist. :)

You need to add that folder to your Windows Path:

https://docs.python.org/2/using/windows.html Taken from this question.

Try Ehcache? It allows you to plug in your own caching expiry algorithms so you could control your peek functionality.

You can serialize to disk, database, across a cluster etc...

1. LocalStorage

   Pros:

   1. Web storage can be viewed simplistically as an improvement on cookies, providing much greater storage capacity. If you look at the Mozilla source code we can see that 5120KB (5MB which equals 2.5 Million chars on Chrome) is the default storage size for an entire domain. This gives you considerably more space to work with than a typical 4KB cookie.
   2. The data is not sent back to the server for every HTTP request (HTML, images, JavaScript, CSS, etc) - reducing the amount of traffic between client and server.
   3. The data stored in localStorage persists until explicitly deleted. Changes made are saved and available for all current and future visits to the site.

   Cons:

   1. It works on same-origin policy. So, data stored will only be available on the same origin.

2. Cookies

   Pros:

   1. Compared to others, there's nothing AFAIK.

   Cons:

   1. The 4K limit is for the entire cookie, including name, value, expiry date etc. To support most browsers, keep the name under 4000 bytes, and the overall cookie size under 4093 bytes.

   2. The data is sent back to the server for every HTTP request (HTML, images, JavaScript, CSS, etc) - increasing the amount of traffic between client and server.

      Typically, the following are allowed:

      • 300 cookies in total
      • 4096 bytes per cookie
      • 20 cookies per domain
      • 81920 bytes per domain(Given 20 cookies of max size 4096 = 81920 bytes.)

3. sessionStorage

   Pros:

   1. It is similar to localStorage.
   2. The data is not persistent i.e. data is only available per window (or tab in browsers like Chrome and Firefox). Data is only available during the page session. Changes made are saved and available for the current page, as well as future visits to the site on the same window. Once the window is closed, the storage is deleted.

   Cons:

   1. The data is available only inside the window/tab in which it was set.
   2. Like localStorage, it works on same-origin policy. So, data stored will only be available on the same origin.

pod update POD_NAME will update latest pod but not update Podfile.lock file.

So, you may update your Podfile with specific version of your pod e.g pod 'POD_NAME', '~> 2.9.0' and then use command pod install

Later, you can remove the specific version naming from your Podfile and can again use pod install. This will helps to keep Podfile.lock updated.

My problem was that I used git (instead of heroku git) to clone the app. Then I had to:

git remote add heroku [email protected]:MyApp.git

Remember to change MyApp to your app name.

Then I could proceed:

git push heroku master

The block approach avoids running the lookup algorithm for every key:

[dict enumerateKeysAndObjectsUsingBlock:^(id key, id value, BOOL* stop) {
  NSLog(@"%@ => %@", key, value);
}];

Even though NSDictionary is implemented as a hashtable (which means that the cost of looking up an element is O(1)), lookups still slow down your iteration by a constant factor.

My measurements show that for a dictionary d of numbers ...

NSMutableDictionary* dict = [NSMutableDictionary dictionary];
for (int i = 0; i < 5000000; ++i) {
  NSNumber* value = @(i);
  dict[value.stringValue] = value;
}

... summing up the numbers with the block approach ...

__block int sum = 0;
[dict enumerateKeysAndObjectsUsingBlock:^(NSString* key, NSNumber* value, BOOL* stop) {
  sum += value.intValue;
}];

... rather than the loop approach ...

int sum = 0;
for (NSString* key in dict)
  sum += [dict[key] intValue];

... is about 40% faster.

EDIT: The new SDK (6.1+) appears to optimise loop iteration, so the loop approach is now about 20% faster than the block approach, at least for the simple case above.

A late answer but I hope it will help anyone visiting here later too..

I will provide categories to save and their respective best methods...

1. Shared Preferences Use this when storing simple values on storage e.g Color theme, app language, last scroll position(in reading apps).. these are simple settings that you would want to persist when the app restarts.. You could, however, use this to store large things(Lists, Maps, Images) but that would require serialization and deserialization.. To learn more on this deserialization and serialization go here.
2. Files This helps a lot when you have data that is defined more by you for example log files, image files and maybe you want to export csv files.. I heard that this type of persistence can be washed by storage cleaners once disk runs out of space.. Am not sure as i have never seen it.. This also can store almost anything but with the help of serialization and deserialization..
3. Saving to a database This is enormously helpful in data which is a bit complex. And I think this doesn't get washed up by disc cleaners as it is stored in AppData(for android).. In this, your data is stored in an SQLite database. Its plugin is SQFLite. Kinds of data that you might wanna put in here are like everything that can be represented by a database.

I'd like to add one important aspect to other answers, which actually explained this topic to me in the best way:

If 2 joined tables contain M and N rows, then cross join will always produce (M x N) rows, but full outer join will produce from MAX(M,N) to (M + N) rows (depending on how many rows actually match "on" predicate).

EDIT:

From logical query processing perspective, CROSS JOIN does indeed always produce M x N rows. What happens with FULL OUTER JOIN is that both left and right tables are "preserved", as if both LEFT and RIGHT join happened. So rows, not satisfying ON predicate, from both left and right tables are added to the result set.

Which characters you must and which you mustn't escape indeed depends on the regex flavor you're working with.

For PCRE, and most other so-called Perl-compatible flavors, escape these outside character classes:

.^$*+?()[{\|

and these inside character classes:

^-]\

For POSIX extended regexes (ERE), escape these outside character classes (same as PCRE):

.^$*+?()[{\|

Escaping any other characters is an error with POSIX ERE.

Inside character classes, the backslash is a literal character in POSIX regular expressions. You cannot use it to escape anything. You have to use "clever placement" if you want to include character class metacharacters as literals. Put the ^ anywhere except at the start, the ] at the start, and the - at the start or the end of the character class to match these literally, e.g.:

[]^-]

In POSIX basic regular expressions (BRE), these are metacharacters that you need to escape to suppress their meaning:

.^$*[\

Escaping parentheses and curly brackets in BREs gives them the special meaning their unescaped versions have in EREs. Some implementations (e.g. GNU) also give special meaning to other characters when escaped, such as \? and +. Escaping a character other than .^$*(){} is normally an error with BREs.

Inside character classes, BREs follow the same rule as EREs.

If all this makes your head spin, grab a copy of RegexBuddy. On the Create tab, click Insert Token, and then Literal. RegexBuddy will add escapes as needed.

I seriously do think that it is code smell if you need to mock static methods, too.

• Static methods to access common functionality? -> Use a singleton instance and inject that
• Third party code? -> Wrap it into your own interface/delegate (and if necessary make it a singleton, too)

The only time this seems overkill to me, is libs like Guava, but you shouldn't need to mock this kind anyway cause it's part of the logic... (stuff like Iterables.transform(..))
That way your own code stays clean, you can mock out all your dependencies in a clean way, and you have an anti corruption layer against external dependencies. I've seen PowerMock in practice and all the classes we needed it for were poorly designed. Also the integration of PowerMock at times caused serious problems
(e.g. https://code.google.com/p/powermock/issues/detail?id=355)

PS: Same holds for private methods, too. I don't think tests should know about the details of private methods. If a class is so complex that it tempts to mock out private methods, it's probably a sign to split up that class...

man ssh gives me this options would could be useful.

-i identity_file Selects a file from which the identity (private key) for RSA or DSA authentication is read. The default is ~/.ssh/identity for protocol version 1, and ~/.ssh/id_rsa and ~/.ssh/id_dsa for pro- tocol version 2. Identity files may also be specified on a per- host basis in the configuration file. It is possible to have multiple -i options (and multiple identities specified in config- uration files).

So you could create an alias in your bash config with something like

alias ssh="ssh -i /path/to/private_key"

I haven't looked into a ssh configuration file, but like the -i option this too could be aliased

-F configfile Specifies an alternative per-user configuration file. If a configuration file is given on the command line, the system-wide configuration file (/etc/ssh/ssh_config) will be ignored. The default for the per-user configuration file is ~/.ssh/config.

Everybody seems to refer to date being a column in the table.
I dont think this is good practice. The word date might just be a keyword in some coding language (maybe Oracle) so please change the columnname date to maybe JDate.
So will the following work better:

SELECT * FROM jokes WHERE JDate >= CURRENT_DATE() ORDER BY JScore DESC;

So we have a table called Jokes with columns JScore and JDate.

Summary:

parseInt():

• Takes a string as a first argument, the radix (An integer which is the base of a numeral system e.g. decimal 10 or binary 2) as a second argument
• The function returns a integer number, if the first character cannot be converted to a number NaN will be returned.
• If the parseInt() function encounters a non numerical value, it will cut off the rest of input string and only parse the part until the non numerical value.
• If the radix is undefined or 0, JS will assume the following:
  • If the input string begins with "0x" or "0X", the radix is 16 (hexadecimal), the remainder of the string is parsed into a number.
  • If the input value begins with a 0 the radix can be either 8 (octal) or 10 (decimal). Which radix is chosen is depending on JS engine implementation. ES5 specifies that 10 should be used then. However, this is not supported by all browsers, therefore always specify radix if your numbers can begin with a 0.
  • If the input value begins with any number, the radix will be 10

Number():

• The Number() constructor can convert any argument input into a number. If the Number() constructor cannot convert the input into a number, NaN will be returned.
• The Number() constructor can also handle hexadecimal number, they have to start with 0x.

Example:

console.log(parseInt('0xF', 16));  // 15_x000D_
_x000D_
// z is no number, it will only evaluate 0xF, therefore 15 is logged_x000D_
console.log(parseInt('0xFz123', 16));_x000D_
_x000D_
// because the radix is 10, A is considered a letter not a number (like in Hexadecimal)_x000D_
// Therefore, A will be cut off the string and 10 is logged_x000D_
console.log(parseInt('10A', 10));  // 10_x000D_
_x000D_
// first character isnot a number, therefore parseInt will return NaN_x000D_
console.log(parseInt('a1213', 10));_x000D_
_x000D_
_x000D_
console.log('\n');_x000D_
_x000D_
_x000D_
// start with 0X, therefore Number will interpret it as a hexadecimal value_x000D_
console.log(Number('0x11'));_x000D_
_x000D_
// Cannot be converted to a number, NaN will be returned, notice that_x000D_
// the number constructor will not cut off a non number part like parseInt does_x000D_
console.log(Number('123A'));_x000D_
_x000D_
// scientific notation is allowed_x000D_
console.log(Number('152e-1'));  // 15.21

First, given that you have a complex data retrieval scenario, are you sure even SQLite is overkill?

You'll end up having an ad hoc, informally-specified, bug-ridden, slow implementation of half of SQLite, paraphrasing Greenspun's Tenth Rule.

That said, you are very right in saying that choosing a single data structure will impact one or more of searching, sorting or counting, so if performance is paramount and your data is constant, you could consider having more than one structure for different purposes.

Above all, measure what operations will be more common and decide which structure will end up costing less.

Here my single-line solution with GSON:

myObject = new Gson().fromJson(new Gson().toJson(myHashMap), MyClass.class);

Here, is the main difference of null=True and blank=True:

The default value of both null and blank is False. Both of these values work at field level i.e., whether we want to keep a field null or blank.

null=True will set the field’s value to NULL i.e., no data. It is basically for the databases column value.

date = models.DateTimeField(null=True)

blank=True determines whether the field will be required in forms. This includes the admin and your own custom forms.

title = models.CharField(blank=True) // title can be kept blank. In the database ("") will be stored. null=True blank=True This means that the field is optional in all circumstances.

epic = models.ForeignKey(null=True, blank=True)
// The exception is CharFields() and TextFields(), which in Django are never saved as NULL. Blank values a

Methods suggest something has to happen to return the value, properties suggest that the value is already there. This is a rule of thumb, sometimes you might want a property that does a little work (i.e. Count), but generally it's a useful way to decide.

1. Download and install Visual C++ Express.

2. Download and extract "freeglut 2.8.0 MSVC Package" from http://www.transmissionzero.co.uk/software/freeglut-devel/

3. Installation for Windows 32 bit:

(a) Copy all files from include/GL folder and paste into C:\Program Files\Microsoft SDKs\Windows\v7.0A\Include\gl folder.

(b) Copy all files from lib folder and paste into C:\Program Files\Microsoft SDKs\Windows\v7.0A\Lib folder.

(c) Copy freeglut.dll and paste into C:\windows\system32 folder.

I tried to add the following options in the /etc/docker/daemon.json. (I used CentOS7)

"add-registry": ["192.168.100.100:5001"],
"block-registry": ["docker.io"],

after that, restarted docker daemon. And it's working without docker.io. I hope this someone will be helpful.

Ok found the answer. exchange() is the best way. Oddly the HttpEntity class doesn't have a setBody() method (it has getBody()), but it is still possible to set the request body, via the constructor.

// Create the request body as a MultiValueMap
MultiValueMap<String, String> body = new LinkedMultiValueMap<String, String>();     

body.add("field", "value");

// Note the body object as first parameter!
HttpEntity<?> httpEntity = new HttpEntity<Object>(body, requestHeaders);

ResponseEntity<MyModel> response = restTemplate.exchange("/api/url", HttpMethod.POST, httpEntity, MyModel.class);

Just change the permission of tmp_file_upload to 755 Following is the command chmod -R 755 tmp_file_upload

Apparently it's possible to do this in jQuery:

$("#tabs").css("cssText", "height: 650px !important;");

If your text will be consumed by non-browsers then it's safer to type the character with the keyboard-combo option shift right bracket because ’ will not be transformed into an apostrophe by a regular XML or JSON parser. (e.g. if you are serving this content to native Android/iOS apps).

Most of the answers here fail to maintain JS Object key-value pairs order. If you have a form of object key-value pairs on the screen that you want to modify, for example, it is important to preserve the order of object entries.

The ES6 way of looping through the JS object and replacing key-value pair with the new pair with a modified key name would be something like:

let newWordsObject = {};

Object.keys(oldObject).forEach(key => {
  if (key === oldKey) {
    let newPair = { [newKey]: oldObject[oldKey] };
    newWordsObject = { ...newWordsObject, ...newPair }
  } else {
    newWordsObject = { ...newWordsObject, [key]: oldObject[key] }
  }
});

The solution preserves the order of entries by adding the new entry in the place of the old one.

Since Java 7 this is very easy and intuitive to do.

List<String> fileContent = new ArrayList<>(Files.readAllLines(FILE_PATH, StandardCharsets.UTF_8));

for (int i = 0; i < fileContent.size(); i++) {
    if (fileContent.get(i).equals("old line")) {
        fileContent.set(i, "new line");
        break;
    }
}

Files.write(FILE_PATH, fileContent, StandardCharsets.UTF_8);

Basically you read the whole file to a List, edit the list and finally write the list back to file.

FILE_PATH represents the Path of the file.

If you are maintaining old code, you probably cannot aim for "the best possible code ever"... That's one case when, in my opinion, you could lower the error_reporting level.

These "undefined index" should only be Notices ; so, you could set the error_reporting level to exclude notices.

One solution is with the error_reporting function, like this :

// Report all errors except E_NOTICE
error_reporting(E_ALL ^ E_NOTICE);

The good thing with this solution is you can set it to exclude notices only when it's necessary (say, for instance, if there is only one or two files with that kind of code)

One other solution would be to set this in php.ini (might not be such a good idea if you are working on several applications, though, as it could mask useful notices ) ; see error_reporting in php.ini.

But I insist : this is acceptable only because you are maintaining an old application -- you should not do that when developping new code !

There are multiple function to printing array content that each has features.

print_r()

Prints human-readable information about a variable.

$arr = ["a", "b", "c"];

echo "<pre>";
print_r($arr);
echo "</pre>";

Array
(
    [0] => a
    [1] => b
    [2] => c
)

var_dump()

Displays structured information about expressions that includes its type and value.

echo "<pre>";
var_dump($arr);
echo "</pre>";

array(3) {
  [0]=>
  string(1) "a"
  [1]=>
  string(1) "b"
  [2]=>
  string(1) "c"
}

var_export()

Displays structured information about the given variable that returned representation is valid PHP code.

echo "<pre>";
var_export($arr);
echo "</pre>";

array (
  0 => 'a',
  1 => 'b',
  2 => 'c',
)

Note that because browser condense multiple whitespace characters (including newlines) to a single space (answer) you need to wrap above functions in <pre></pre> to display result in correct format.

Also there is another way to printing array content with certain conditions.

echo

Output one or more strings. So if you want to print array content using echo, you need to loop through array and in loop use echo to printing array items.

foreach ($arr as $key=>$item){
    echo "$key => $item <br>";
}

0 => a 
1 => b 
2 => c 

ArrayList myList = new ArrayList(10);

//  myList.add(3, "DDD");
//  myList.add(9, "III");
    myList.add(0, "AAA");
    myList.add(1, "BBB");

    for(String item:myList){
        System.out.println("inside list : "+item);
    }

/*Declare the initial capasity of arraylist is nothing but saving shifting time in internally; when we add the element internally it check the capasity to increase the capasity, you could add the element at 0 index initially then 1 and so on. */

A Nuget solved my problem:Geocoding.Google 4.0.0. Install it so not necessary to write extra classes etc.

Using the graceful-fs module by Isaac Schlueter (node.js maintainer) is probably the most appropriate solution. It does incremental back-off if EMFILE is encountered. It can be used as a drop-in replacement for the built-in fs module.

1. I think its better you read data of text file in DataSet

2. Try out SqlBulkCopy - Bulk Insert into SQL from C# App

   // connect to SQL
   using (SqlConnection connection = new SqlConnection(connString))
   {
       // make sure to enable triggers
       // more on triggers in next post
       SqlBulkCopy bulkCopy = new SqlBulkCopy(
           connection, 
           SqlBulkCopyOptions.TableLock | 
           SqlBulkCopyOptions.FireTriggers | 
           SqlBulkCopyOptions.UseInternalTransaction,
           null
           );
   
       // set the destination table name
       bulkCopy.DestinationTableName = this.tableName;
       connection.Open();
   
       // write the data in the "dataTable"
       bulkCopy.WriteToServer(dataTable);
       connection.Close();
   }
   // reset
   this.dataTable.Clear();
   

or

after doing step 1 at the top

2. Create XML from DataSet
3. Pass XML to database and do bulk insert

you can check this article for detail : Bulk Insertion of Data Using C# DataTable and SQL server OpenXML function

But its not tested with 2 million record, it will do but consume memory on machine as you have to load 2 million record and insert it.

I think that CONTAINS took longer and used Merge because you had a dash("-") in your query adventure-works.com.

The dash is a break word so the CONTAINS searched the full-text index for adventure and than it searched for works.com and merged the results.

Since PHP 5.4 you can use:

htmlspecialchars($string, ENT_XML1);

You should specify the encoding, such as:

htmlspecialchars($string, ENT_XML1, 'UTF-8');

Update

Note that the above will only convert:

• & to &
• < to <
• > to >

If you want to escape text for use in an attribute enclosed in double quotes:

htmlspecialchars($string, ENT_XML1 | ENT_COMPAT, 'UTF-8');

will convert " to " in addition to &, < and >.

And if your attributes are enclosed in single quotes:

htmlspecialchars($string, ENT_XML1 | ENT_QUOTES, 'UTF-8');

will convert ' to ' in addition to &, <, > and ".

(Of course you can use this even outside of attributes).

See the manual entry for htmlspecialchars.

Once you have you date parsed, I use this utility function to add hours, minutes or seconds:

public class DateTimeUtils {
    private static final long ONE_HOUR_IN_MS = 3600000;
    private static final long ONE_MIN_IN_MS = 60000;
    private static final long ONE_SEC_IN_MS = 1000;

    public static Date sumTimeToDate(Date date, int hours, int mins, int secs) {
        long hoursToAddInMs = hours * ONE_HOUR_IN_MS;
        long minsToAddInMs = mins * ONE_MIN_IN_MS;
        long secsToAddInMs = secs * ONE_SEC_IN_MS;
        return new Date(date.getTime() + hoursToAddInMs + minsToAddInMs + secsToAddInMs);
    }
}

Be careful when adding long periods of time, 1 day is not always 24 hours (daylight savings-type adjustments, leap seconds and so on), Calendar is recommended for that.

You need to go here https://security.google.com/settings/security/apppasswords

then select Gmail and then select device. then click on Generate. Simply Copy & Paste password which is generated by Google.

You can use color code also.

 const marker: Marker = this.map.addMarkerSync({
    icon: '#008000',
    animation: 'DROP',
    position: {lat: 39.0492127, lng: -111.1435662},
    map: this.map,
 });

I've found that you can use any subset condition for a given column by wrapping it in []. For instance, you have a df with columns ['Product','Time', 'Year', 'Color']

And let's say you want to include products made before 2014. You could write,

df[df['Year'] < 2014]

To return all the rows where this is the case. You can add different conditions.

df[df['Year'] < 2014][df['Color' == 'Red']

Then just choose the columns you want as directed above. For instance, the product color and key for the df above,

df[df['Year'] < 2014][df['Color'] == 'Red'][['Product','Color']]

If the external configuration file is also valid batch file, you can just use:

call externalconfig.bat

inside your script. Try creating following a.bat:

@echo off
call b.bat
echo %MYVAR%

and b.bat:

set MYVAR=test

Running a.bat should generate output:

test

In an attempt to find a way to make the target cell for the intersect method a name table array, I stumbled across a simple way to run something when ANY cell or set of cells on a particular sheet changes. This code is placed in the worksheet module as well:

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count > 0 Then
'mycode here
end if
end sub

You are using DictWriter.writerows() which expects a list of dicts, not a dict. You want DictWriter.writerow() to write a single row.

You will also want to use DictWriter.writeheader() if you want a header for you csv file.

You also might want to check out the with statement for opening files. It's not only more pythonic and readable but handles closing for you, even when exceptions occur.

Example with these changes made:

import csv

my_dict = {"test": 1, "testing": 2}

with open('mycsvfile.csv', 'w') as f:  # You will need 'wb' mode in Python 2.x
    w = csv.DictWriter(f, my_dict.keys())
    w.writeheader()
    w.writerow(my_dict)

Which produces:

test,testing
1,2

There's another CURL method if you are going that way.

This is pretty straightforward once you get your head around the way the PHP curl extension works, combining various flags with setopt() calls. In this example I've got a variable $xml which holds the XML I have prepared to send - I'm going to post the contents of that to example's test method.

$url = 'http://api.example.com/services/xmlrpc/';
$ch = curl_init($url);

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);
//process $response

First we initialised the connection, then we set some options using setopt(). These tell PHP that we are making a post request, and that we are sending some data with it, supplying the data. The CURLOPT_RETURNTRANSFER flag tells curl to give us the output as the return value of curl_exec rather than outputting it. Then we make the call and close the connection - the result is in $response.

You can do the following:

TimeSpan duration = b - a;

There's plenty of built in methods in the timespan class to do what you need, i.e.

duration.TotalSeconds
duration.TotalMinutes

More info can be found here.

I think that the usage of @Html.LabelForModel() should be explained in more detail.

The LabelForModel Method returns an HTML label element and the property name of the property that is represented by the model.

You could refer to the following code:

Code in model:

using System.ComponentModel;

[DisplayName("MyModel")]
public class MyModel
{
    [DisplayName("A property")]
    public string Test { get; set; }
}

Code in view:

@Html.LabelForModel()
<div class="form-group">

    @Html.LabelFor(model => model.Test, new { @class = "control-label col-md-2" })

    <div class="col-md-10">
        @Html.EditorFor(model => model.Test)
        @Html.ValidationMessageFor(model => model.Test)
    </div>
</div>

I searched for a solution to parse very large files (gbs) line by line using a stream. All the third-party libraries and examples did not suit my needs since they processed the files not line by line (like 1 , 2 , 3 , 4 ..) or read the entire file to memory

The following solution can parse very large files, line by line using stream & pipe. For testing I used a 2.1 gb file with 17.000.000 records. Ram usage did not exceed 60 mb.

First, install the event-stream package:

npm install event-stream

Then:

var fs = require('fs')
    , es = require('event-stream');

var lineNr = 0;

var s = fs.createReadStream('very-large-file.csv')
    .pipe(es.split())
    .pipe(es.mapSync(function(line){

        // pause the readstream
        s.pause();

        lineNr += 1;

        // process line here and call s.resume() when rdy
        // function below was for logging memory usage
        logMemoryUsage(lineNr);

        // resume the readstream, possibly from a callback
        s.resume();
    })
    .on('error', function(err){
        console.log('Error while reading file.', err);
    })
    .on('end', function(){
        console.log('Read entire file.')
    })
);

Please let me know how it goes!

Interfaces where a fetature added to java to allow multiple inheritance. The developers of Java though/realized that having multiple inheritance was a "dangerous" feature, that is why the came up with the idea of an interface.

multiple inheritance is dangerous because you might have a class like the following:

class Box{
    public int getSize(){
       return 0;
    }
    public int getArea(){
       return 1;
    }

}

class Triangle{
    public int getSize(){
       return 1;
    }
    public int getArea(){
       return 0;
    }

}

class FunckyFigure extends Box, Triable{
   // we do not implement the methods we will used the inherited ones
}

Which would be the method that should be called when we use

   FunckyFigure.GetArea(); 

All the problems are solved with interfaces, because you do know you can extend the interfaces and that they wont have classing methods... ofcourse the compiler is nice and tells you if you did not implemented a methods, but I like to think that is a side effect of a more interesting idea.

Try this:

Intent logout_intent = new Intent(DashboardActivity.this, LoginActivity.class);
logout_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
logout_intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
logout_intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivity(logout_intent);
finish();

Using dictionaries should be right way to keep the variables and associated values, and you may use this:

dict_ = {}
for i in range(9):
     dict_['string%s' % i]  = 'Hello'

But if you want to add the variables to the local variables you can use:

for i in range(9):
     exec('string%s = Hello' % i)

And for example if you want to assign values 0 to 8 to them, you may use:

for i in range(9):
     exec('string%s = %s' % (i,i))

The a == b expression invokes A.__eq__, since it exists. Its code includes self.value == other. Since int's don't know how to compare themselves to B's, Python tries invoking B.__eq__ to see if it knows how to compare itself to an int.

If you amend your code to show what values are being compared:

class A(object):
    def __eq__(self, other):
        print("A __eq__ called: %r == %r ?" % (self, other))
        return self.value == other
class B(object):
    def __eq__(self, other):
        print("B __eq__ called: %r == %r ?" % (self, other))
        return self.value == other

a = A()
a.value = 3
b = B()
b.value = 4
a == b

it will print:

A __eq__ called: <__main__.A object at 0x013BA070> == <__main__.B object at 0x013BA090> ?
B __eq__ called: <__main__.B object at 0x013BA090> == 3 ?

In this particular case, the following should work:

serverConnectionHandler = new ServerConnections(_address) {
    public void newConnection(Socket _socket) {
        System.out.println("A function of my child class was called.");
    }
};

It's an anonymous subclass.

The std::string object returned by ss.str() is a temporary object that will have a life time limited to the expression. So you cannot assign a pointer to a temporary object without getting trash.

Now, there is one exception: if you use a const reference to get the temporary object, it is legal to use it for a wider life time. For example you should do:

#include <string>
#include <sstream>
#include <iostream>

using namespace std;

int main()
{
    stringstream ss("this is a string\n");

    string str(ss.str());

    const char* cstr1 = str.c_str();

    const std::string& resultstr = ss.str();
    const char* cstr2 = resultstr.c_str();

    cout << cstr1       // Prints correctly
        << cstr2;       // No more error : cstr2 points to resultstr memory that is still alive as we used the const reference to keep it for a time.

    system("PAUSE");

    return 0;
}

That way you get the string for a longer time.

Now, you have to know that there is a kind of optimisation called RVO that say that if the compiler see an initialization via a function call and that function return a temporary, it will not do the copy but just make the assigned value be the temporary. That way you don't need to actually use a reference, it's only if you want to be sure that it will not copy that it's necessary. So doing:

 std::string resultstr = ss.str();
 const char* cstr2 = resultstr.c_str();

would be better and simpler.

As a type that contains children, I'm using:

type ChildrenContainer = Pick<JSX.IntrinsicElements["div"], "children">

This children container type is generic enough to support all the different cases and also aligned with the ReactJS API.

So, for your example it would be something like:

const layout = ({ children }: ChildrenContainer) => (
    <Aux>
        <div>Toolbar, SideDrawer, Backdrop</div>
        <main>
            {children}
        </main>
    <Aux/>
)

Is it possible (work only online and load only your page or file): https://w3schools.com/xml/xml_http.asp Try my code:

function load_page(){
qr=new XMLHttpRequest();
qr.open('get','YOUR_file_or_page.htm');
qr.send();
qr.onload=function(){YOUR_div_id.innerHTML=qr.responseText}
};load_page();

qr.onreadystatechange instead qr.onload also use.

Build an expression that matches, and use !match()... (logical negation) That's probably how grep does anyway...

You should add the g modifier so that sed performs a global substitution of the contents of the pattern buffer:

echo dog dog dos | sed -e 's:dog:log:g'

For a fantastic documentation on sed, check http://www.grymoire.com/Unix/Sed.html. This global flag is explained here: http://www.grymoire.com/Unix/Sed.html#uh-6

The official documentation for GNU sed is available at http://www.gnu.org/software/sed/manual/

Expanding on the answers provided here.

You can just do set idx = 1 to set a variable, but that syntax is not recommended because the variable name may clash with a set sub-command. As an example set w=1 would not be valid.

This means that you should prefer the syntax: set variable idx = 1 or set var idx = 1.

Last but not least, you can just use your trusty old print command, since it evaluates an expression. The only difference being that he also prints the result of the expression.

(gdb) p idx = 1
$1 = 1

You can read more about gdb here.

GridView1.Columns[columnIndex].Visible = false;

HISTTIMEFORMAT="%d/%m/%y %H:%M "

For any commands typed prior to this, it will not help since they will just get a default time of when you turned history on, but it will log the time of any further commands after this.

If you want it to log history for permanent, you should put the following line in your ~/.bashrc

export HISTTIMEFORMAT="%d/%m/%y %H:%M "

Put i++ somewhere at the end of your loop.

In the above code, the 0 position of the array is overwritten because i is not incremented in each loop.

FYI: the below is doing a redundant search:

if(keys[i].equals(DATE)){                 
   date_value[i] = map.get(keys[i]);              
} else if(keys[i].equals(VALUE)){              
   value_values[i] = map.get(keys[i]);             
} 

replace with

if(keys[i].equals(DATE)){                 
   date_value[i] = mapping.getValue();
} else if(keys[i].equals(VALUE)){              
   value_values[i] = mapping.getValue()
} 

Another issue is that you are using i for date_value and value_values. This is not valid unless you intend to have null values in your array.

An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again. If a negated pattern matches, this will override lower precedence patterns sources.

Thanks to @Jimmy for this.

1. GETDATE() or GETUTCDATE() are now superseded by the richer SYSDATETIME, SYSUTCDATETIME, and SYSDATETIMEOFFSET (in SQL 2008)
2. Yes, I don't think ANSI has ever declared anything, and so each manufacturer has their own.
3. That would be NOW()

Hope this helps...

Downloading with Git using Windows CMD from a GitHub project

Found this post and I realize it's a bit old, but I think I might have an answer. This handles the click on the cross, backspacing and hitting the ESC key. I am sure it could probably be written better - I'm still relatively new to javascript. Here is what I ended up doing - I am using jQuery (v1.6.4):

var searchVal = ""; //create a global var to capture the value in the search box, for comparison later
$(document).ready(function() {
  $("input[type=search]").keyup(function(e) {
    if (e.which == 27) {  // catch ESC key and clear input
      $(this).val('');
    }
    if (($(this).val() === "" && searchVal != "") || e.which == 27) {
      // do something
      searchVal = "";
    }
    searchVal = $(this).val();
  });
  $("input[type=search]").click(function() {
    if ($(this).val() != filterVal) {
      // do something
      searchVal = "";
    }
  });
});

I found a simple solution, try this:

var Ocasiao = "";    
$('#ctl00_rdlOcasioesMarcas input').each(function() { if (this.checked) { Ocasiao = this.value } });

This worked best for me:

<div class="card bg-light p-3">
 <p class="mb-0">Some text here</p>
</div>

A little hacky, but I created an array called "console", and anytime I wanted to output to console I pushed to the array. Then whenever I wanted to see the actual output, I just returned console instead of whatever I was returning before.

    //return 'console' //uncomment to output console
    return "actual output";
}

Using Confluent's REST Proxy API v3:

curl -X GET -H "Accept: application/vnd.api+json" localhost:8082/v3/clusters

where localhost:8082 is Kafka Proxy address.

You should generally try to avoid <b> and <i>. They were introduced for layouting the page (changing the way how it looks) in early HMTL versions prior to the creation of CSS, like the meanwhile removed font tag, and were mainly kept for backward compatibility and because some forums allow inline HTML and that's an easy way to change the look of text (like BBCode using [i], you can use <i> and so on).

Since the creation of CSS, layouting is actually nothing that should be done in HTML anymore, that's why CSS has been created in the first place (HTML == Structure, CSS == Layout). These tags may as well vanish in the future, after all you can just use CSS and span tags to make text bold/italic if you need a "meaningless" font variation. HTML 5 still allows them but declares that marking text that way has no meaning.

<em> and <strong> on the other hand only says that something is "emphasized" or "strongly emphasized", it leaves it completely open to the browser how to render it. Most browsers will render em as italic and strong as bold as the standard suggests by default, but they are not forced to do that (they may use different colors, font sizes, fonts, whatever). You can use CSS to change the behavior the way you desire. You can make em bold if you like and strong bold and red, for example.

Try this:

function MyController($scope) {
    $scope.form = {
        name: 'my name',
        surname: 'surname'
    }

    function track(newValue, oldValue, scope) {
        console.log('changed');
    };

    $scope.$watch('form.name', track);
}

Use Scalable DP

Although making a different layout for different screen sizes is theoretically a good idea, it can get very difficult to accommodate for all screen dimensions, and pixel densities. Having over 20+ different dimens.xml files as suggested in the above answers, is not easy to manage at all.

How To Use:

To use sdp:

1. Include implementation 'com.intuit.sdp:sdp-android:1.0.5' in your build.gradle,

2. Replace any dp value such as 50dp with a @dimen/50_sdp like so:

   <TextView
    android:layout_width="@dimen/_50sdp"
    android:layout_height="@dimen/_50sdp"
    android:text="Hello World!" />
   

How It Works:

sdp scales with the screen size because it is essentially a huge list of different dimens.xml for every possible dp value.

See It In Action:

Here it is on three devices with widely differing screen dimensions, and densities:

Note that the sdp size unit calculation includes some approximation due to some performance and usability constraints.

Ruby versions >= 2.4 has an Enumerable#sum method.

And to get floating point average, you can use Integer#fdiv

arr = [0,4,8,2,5,0,2,6]

arr.sum.fdiv(arr.size)
# => 3.375

For older versions:

arr.reduce(:+).fdiv(arr.size)
# => 3.375

First, you need to create your branch locally

git checkout -b your_branch

After that, you can work locally in your branch, when you are ready to share the branch, push it. The next command push the branch to the remote repository origin and tracks it

git push -u origin your_branch

Your Teammates/colleagues can push to your branch by doing commits and then push explicitly

... work ...
git commit
... work ...
git commit
git push origin HEAD:refs/heads/your_branch 

This is not bullet but you can consider it. As there is nothing like big dot.

I used below symbol in the description and its working fine.

? Black Circle

New Moon

Full Moon

Diamond With a Dot

Small Orange Diamond

? Gear

Black Flag

White Flag

? Play Button

? Fast-Forward Button

? Heavy Large Circle

? Eight-Pointed Star

? Black Medium Square

? White Medium-Small Square

? Black Medium-Small Square

? Black Large Square

You just need to copy and paste it over description. Below is the result.

The only (and unfailing) way to resolve this issue is building test from command line:

xcodebuild -workspace MyProject.xcworkspace/ -scheme MyScheme -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone 7,OS=10.3.1' test

So, at this point, your compilation will surely fail but you'll see all linking problem. In my case, I had several problem such as:

• ld: framework 'Foo' not found
  To resolve this, you need to on your target, BuildSettings->Linking->OtherLinkerFlags and remove 'Foo' framework .
• Use of unresolved identifier 'ClassName' .
  To resolve this, I need to add/check file's target membership to UITest target too.

Other possible problems will be raised by xcodebuild and you can easily fix it.

PHP has the new nice filter_input functions now, that for instance liberate you from finding 'the ultimate e-mail regex' now that there is a built-in FILTER_VALIDATE_EMAIL type

My own filter class (uses JavaScript to highlight faulty fields) can be initiated by either an ajax request or normal form post. (see the example below)

/**
 *  Pork.FormValidator
 *  Validates arrays or properties by setting up simple arrays. 
 *  Note that some of the regexes are for dutch input!
 *  Example:
 * 
 *  $validations = array('name' => 'anything','email' => 'email','alias' => 'anything','pwd'=>'anything','gsm' => 'phone','birthdate' => 'date');
 *  $required = array('name', 'email', 'alias', 'pwd');
 *  $sanitize = array('alias');
 *
 *  $validator = new FormValidator($validations, $required, $sanitize);
 *                  
 *  if($validator->validate($_POST))
 *  {
 *      $_POST = $validator->sanitize($_POST);
 *      // now do your saving, $_POST has been sanitized.
 *      die($validator->getScript()."<script type='text/javascript'>alert('saved changes');</script>");
 *  }
 *  else
 *  {
 *      die($validator->getScript());
 *  }   
 *  
 * To validate just one element:
 * $validated = new FormValidator()->validate('blah@bla.', 'email');
 * 
 * To sanitize just one element:
 * $sanitized = new FormValidator()->sanitize('<b>blah</b>', 'string');

Of course, keep in mind that you need to do your sql query escaping too depending on what type of db your are using (mysql_real_escape_string() is useless for an sql server for instance). You probably want to handle this automatically at your appropriate application layer like an ORM. Also, as mentioned above: for outputting to html use the other php dedicated functions like htmlspecialchars ;)

For really allowing HTML input with like stripped classes and/or tags depend on one of the dedicated xss validation packages. DO NOT WRITE YOUR OWN REGEXES TO PARSE HTML!

When taking Distinct we have to cast into IEnumerable too. If list is model means, need to write code like this

 IEnumerable<T> ids = list.Select(x => x).Distinct();

From @NHG comment — works perfectly

{% for post in posts|slice(0,10) %}

ArrayList<String>[][] list = new ArrayList[10][10];
list[0][0] = new ArrayList<>();
list[0][0].add("test");

In my fairly complex scenario the accepted answer for how to do this in Chrome doesn't work for me. You may want to try the Firefox debugger instead (part of the Firefox developer tools), which shows all of the 'Sources', including those that are part of an iFrame

You want $_SERVER['REQUEST_URI']. From the docs:

'REQUEST_URI'

The URI which was given in order to access this page; for instance, '/index.html'.

UPDATE [table]
SET [column] = REPLACE([column], '/foo/', '/bar/')

Function

Public Function ArrayLen(arr As Variant) As Integer
    ArrayLen = UBound(arr) - LBound(arr) + 1
End Function

Usage

Dim arr(1 To 3) As String  ' Array starting at 1 instead of 0: nightmare fuel
Debug.Print ArrayLen(arr)  ' Prints 3.  Everything's going to be ok.

I went ahead and downloaded the project from the link you provided: http://javapapers.com/android/android-chat-bubble/

Since this is an old tutorial, you simply need to upgrade the software, gradle, the android build tools and plugin.

Make sure you have the latest Gradle and Android Studio:

• https://www.gradle.org/
• http://tools.android.com/tech-docs/new-build-system/version-compatibility

build.gradle:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

app/build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.3'

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 23
        versionCode 1
        versionName '1.0'
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:23.2.1'
}

Then run gradle:

gradle installDebug

I know the OP is asking for a CSS-only solution. But in case anyone landing here from the Magic Google ends up requiring a JavaScript solution, here's a one-liner:

capitalize = str => str[0].toUpperCase() + str.substr(1);

e.g.:

capitalize('foo bar baz'); // -> 'Foo bar baz'

I vote for a third solution. I use this in my projects and Symfony uses something like this too:

public function __call($val, $x) {
    if(substr($val, 0, 3) == 'get') {
        $varname = strtolower(substr($val, 3));
    }
    else {
        throw new Exception('Bad method.', 500);
    }
    if(property_exists('Yourclass', $varname)) {
        return $this->$varname;
    } else {
        throw new Exception('Property does not exist: '.$varname, 500);
    }
}

This way you have automated getters (you can write setters too), and you only have to write new methods if there is a special case for a member variable.

My favourites have always been

use constant FALSE => 1==0;
use constant TRUE => not FALSE;

which is completely independent from the internal representation.

Giving an element the attribute readonly will give that element the readonly status. It doesn't matter what value you put after it or if you put any value after it, it will still see it as readonly. Putting readonly="false" won't work.

Suggested is to use the W3C standard, which is readonly="readonly".

Shortcut Alt+Enter shows intention actions where you can choose "Add Javadoc".

For the replacement string and the replacement pattern as specified by $. here a resume:

link to doc : here

"hello _there_".replace(/_(.*?)_/g, "<div>$1</div>")

Note:

If you want to have a $ in the replacement string use $$. Same as with vscode snippet system.

import random
import time
import sys
while True:
    x=random.randint(1,100)
    print('''Guess my number--it's from 1 to 100.''')
    z=0
    while True:
        z=z+1
        xx=int(str(sys.stdin.readline()))
        if xx > x:
            print("Too High!")
        elif xx < x:
            print("Too Low!")
        elif xx==x:
            print("You Win!! You used %s guesses!"%(z))
            print()
            break
        else:
            break

in this, I first string the number str(), which converts it into an inoperable number. Then, I int() integerize it, to make it an operable number. I just tested your problem on my IDLE GUI, and it said that 49.8 < 50.

There are apparently distributions or custom builds in which the ability to set Task Tags for non-Java files is not present. This post mentions that ColdFusion Builder (built on Eclipse) does not let you set non-Java Task Tags, but the beta version of CF Builder 2 does. (I know the OP wasn't using CF Builder, but I am, and I was wondering about this question myself ... because he didn't see the ability to set non-Java tags, I thought others might be in the same position.)

The main reason that you cannot inherit a static class is that they are abstract and sealed (this also prevents any instance of them from being created).

So this:

static class Foo { }

compiles to this IL:

.class private abstract auto ansi sealed beforefieldinit Foo
  extends [mscorlib]System.Object
 {
 }

For a bit of completeness - this query will create a query to give you a count of all of the tables for a given owner.

select 
  DECODE(rownum, 1, '', ' UNION ALL ') || 
  'SELECT ''' || table_name || ''' AS TABLE_NAME, COUNT(*) ' ||
  ' FROM ' || table_name  as query_string 
 from all_tables 
where owner = :owner;

The output is something like

SELECT 'TAB1' AS TABLE_NAME, COUNT(*) FROM TAB1
 UNION ALL SELECT 'TAB2' AS TABLE_NAME, COUNT(*) FROM TAB2
 UNION ALL SELECT 'TAB3' AS TABLE_NAME, COUNT(*) FROM TAB3
 UNION ALL SELECT 'TAB4' AS TABLE_NAME, COUNT(*) FROM TAB4

Which you can then run to get your counts. It's just a handy script to have around sometimes.

Converting the list to a data frame within the append function works, also when applied in a loop

import pandas as pd
mylist = [1,2,3]
df = pd.DataFrame()
df = df.append(pd.DataFrame(data[mylist]))

After decoding, it looks like the data is a repeating structure that's 8 bytes long, or some multiple thereof. It's just binary data though; what it might mean, I have no idea. There are 2064 entries, which means that it could be a list of 2064 8-byte items down to 129 128-byte items.

If you have a value and want to find the key, use array_search() like this:

$arr = array ('first' => 'a', 'second' => 'b', );
$key = array_search ('a', $arr);

$key will now contain the key for value 'a' (that is, 'first').

While sort takes O(n log(n)) time, I prefer using

awk '!seen[$0]++'

awk '!seen[$0]++' is an abbreviation for awk '!seen[$0]++ {print}', print line(=$0) if seen[$0] is not zero. It take more space but only O(n) time.

So Far, pydub worked best for me. Modules like playsound will also do the job, But It has only one single feature. pydub has many features like slicing the song(file), Adjusting the volume etc...

It is as simple as slicing the lists in python.

So, When it comes to just playing, It is as shown as below.

from pydub import AudioSegment
from pydub.playback import play

path_to_file = r"Music/Harry Potter Theme Song.mp3"
song = AudioSegment.from_mp3(path_to_file)
play(song)

An interface can extend multiple interfaces.

A class can implement multiple interfaces.

However, a class can only extend a single class.

Careful how you use the words extends and implements when talking about interface and class.

From this site:

http://www.tek-tips.com/viewthread.cfm?qid=1500861&page=1

C# does allow the use of the [Optional] attribute (from VB, though not functional in C#). So you can have a method like this:

using System.Runtime.InteropServices;
public void Foo(int a, int b, [Optional] int c)
{
  ...
}

In our API wrapper, we detect optional parameters (ParameterInfo p.IsOptional) and set a default value. The goal is to mark parameters as optional without resorting to kludges like having "optional" in the parameter name.

The duplicate values in any column can be deleted with a simple for loop.

Sub remove()
Dim a As Long
For a = Cells(Rows.Count, 1).End(xlUp).Row To 1 Step -1
If WorksheetFunction.CountIf(Range("A1:A" & a), Cells(a, 1)) > 1 Then Rows(a).Delete
Next
End Sub

I know that this question is accepted and has a bit of age but this might be helpful for some people who still find it relevant. Although the outcome is not a full RESTful API the API Builder mini lib for PHP allows you to easily transform MySQL databases into web accessible JSON APIs.

Also faced the same problem when using unmanaged c/c++ dll file in c# environment.

1.Checked the compatibility of dll with 32bit or 64bit CPU.

2.Checked the correct paths of DLL .bin folder, system32/sysWOW64 , or given path.

3.Checked if PDB(Programme Database) files are missing.This video gives you ans best undestand about pdb files.

When running 32-bit C/C++ binary code in 64bit system, could arise this because of platform incompatibility. You can change it from Build>Configuration manager.

After clean the logs using any of the methods described above you can also disable them in your app/etc/local.xml

Use the matplotlib savefig function with the keyword argument transparent=True to save the image as a png file.

In [30]: x = np.linspace(0,6,31)

In [31]: y = np.exp(-0.5*x) * np.sin(x)

In [32]: plot(x, y, 'bo-')
Out[32]: [<matplotlib.lines.Line2D at 0x3f29750>]            

In [33]: savefig('demo.png', transparent=True)

Result:

Of course, that plot doesn't demonstrate the transparency. Here's a screenshot of the PNG file displayed using the ImageMagick display command. The checkerboard pattern is the background that is visible through the transparent parts of the PNG file.

Just use the formula

=A8*60*24

ALTER TABLE myTable ALTER COLUMN myColumn {DataType} NULL

where {DataType} is the current data type of that column (For example int or varchar(10))

One way to deal with asynchronous work like this is to use a callback function, eg:

function firstFunction(_callback){
    // do some asynchronous work
    // and when the asynchronous stuff is complete
    _callback();    
}

function secondFunction(){
    // call first function and pass in a callback function which
    // first function runs when it has completed
    firstFunction(function() {
        console.log('huzzah, I\'m done!');
    });    
}

As per @Janaka Pushpakumara's suggestion, you can now use arrow functions to achieve the same thing. For example:

firstFunction(() => console.log('huzzah, I\'m done!'))

Update: I answered this quite some time ago, and really want to update it. While callbacks are absolutely fine, in my experience they tend to result in code that is more difficult to read and maintain. There are situations where I still use them though, such as to pass in progress events and the like as parameters. This update is just to emphasise alternatives.

Also the original question doesn't specificallty mention async, so in case anyone is confused, if your function is synchronous, it will block when called. For example:

doSomething()
// the function below will wait until doSomething completes if it is synchronous
doSomethingElse()

If though as implied the function is asynchronous, the way I tend to deal with all my asynchronous work today is with async/await. For example:

const secondFunction = async () => {
  const result = await firstFunction()
  // do something else here after firstFunction completes
}

IMO, async/await makes your code much more readable than using promises directly (most of the time). If you need to handle catching errors then use it with try/catch. Read about it more here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function .

Definitely the easiest way to do that is using Gson's default parsing function fromJson().

There is an implementation of this function suitable for when you need to deserialize into any ParameterizedType (e.g., any List), which is fromJson(JsonElement json, Type typeOfT).

In your case, you just need to get the Type of a List<String> and then parse the JSON array into that Type, like this:

import java.lang.reflect.Type;
import com.google.gson.reflect.TypeToken;

JsonElement yourJson = mapping.get("servers");
Type listType = new TypeToken<List<String>>() {}.getType();

List<String> yourList = new Gson().fromJson(yourJson, listType);

In your case yourJson is a JsonElement, but it could also be a String, any Reader or a JsonReader.

You may want to take a look at Gson API documentation.

All you should need to do is:

# if the file in the right place isn't already committed:
git add <path to desired file>

# remove the "both deleted" file from the index:
git rm --cached ../public/images/originals/dog.ai

# commit the merge:
git commit

You can create a temp table variable and insert the data into it, then insert the data into your actual table by selecting it from the temp table.

 declare @TableVar table 
 (
    firstCol varchar(50) NOT NULL,
    secondCol varchar(50) NOT NULL
 )

BULK INSERT @TableVar FROM 'PathToCSVFile' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\n')
GO

INSERT INTO dbo.ExistingTable
(
    firstCol,
    secondCol
)
SELECT firstCol,
       secondCol
FROM @TableVar

GO

If you want to install CocoaPods first time for your project.

Example :Here we will install "Alamofire" sdk using cocoa pods step by step.

Step 1. Open Terminal and hit command and then press “Enter” key

sudo gem install cocoapods

Step 2. If it asks, you should provide system password and then press “Enter” key

Step 3. With command “cd” and give the path of your project and then press “Enter” key

Note : type "cd" command then space and drag project folder to the terminal it will take project path as shown below (Here my project name is : Simple Alamofire)

cd /Users/ramdhanchoudhary/Documents/Swift\ Workspace/Simple\ Alamofire

Step 4. Create a pod file in your project by terminal by command “touch Podfile” and press “Enter”

touch Podfile

Step 5. Then, open “Podfile” by terminal command “open Podfile” and press “Enter”

open Podfile

Step 6. Now type following code in opened pod file then save and close file

source 'https://github.com/CocoaPods/Specs.git'
    platform :ios, '10.0'
    use_frameworks!

    target '<Your Target Name>' do
            pod 'Alamofire', '~> 4.0'
    end

Step 7. Back in Terminal type command “Pod install” and then press “Enter” Key.

Pod install

Step 8. Wait for the install to get complete 100% its around 650+ MB

Step 9. That's it goto project folder and open below file

.xcworkspace

Step 10. Import Alamofire class and use!!

import Alamofire

I know this is a fairly old question, but there is now a nicer API available natively in newer browsers. The fetch() method allow you to make web requests. For example, to request some json from /get-data:

var opts = {
  method: 'GET',      
  headers: {}
};
fetch('/get-data', opts).then(function (response) {
  return response.json();
})
.then(function (body) {
  //doSomething with body;
});

See here for more details.

Make sure you have called the CreateCriteria(typeof(DomainObjectType)) method on Session for the domain object which you intent to fetch from DB.

Maybe you are looking for this plyr::revalue function:

mutate(dat, x = revalue(x, c("A" = "B")))

You can see plyr::mapvalues too.

I think LayeredPane is your best bet here. You would need a third panel though to contain A and B. This third panel would be the layeredPane and then panel A and B could still have a nice LayoutManagers. All you would have to do is center B over A and there is quite a lot of examples in the Swing trail on how to do this. Tutorial for positioning without a LayoutManager.

public class Main {
    private JFrame frame = new JFrame();
    private JLayeredPane lpane = new JLayeredPane();
    private JPanel panelBlue = new JPanel();
    private JPanel panelGreen = new JPanel();
    public Main()
    {
        frame.setPreferredSize(new Dimension(600, 400));
        frame.setLayout(new BorderLayout());
        frame.add(lpane, BorderLayout.CENTER);
        lpane.setBounds(0, 0, 600, 400);
        panelBlue.setBackground(Color.BLUE);
        panelBlue.setBounds(0, 0, 600, 400);
        panelBlue.setOpaque(true);
        panelGreen.setBackground(Color.GREEN);
        panelGreen.setBounds(200, 100, 100, 100);
        panelGreen.setOpaque(true);
        lpane.add(panelBlue, new Integer(0), 0);
        lpane.add(panelGreen, new Integer(1), 0);
        frame.pack();
        frame.setVisible(true);
    }


    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        new Main();
    }

}

You use setBounds to position the panels inside the layered pane and also to set their sizes.

Edit to reflect changes to original post You will need to add component listeners that detect when the parent container is being resized and then dynamically change the bounds of panel A and B.

A somewhat more principled approach is to use a global descriptor to compare images, such as GIST or CENTRIST. A hash function, as described here, also provides a similar solution.

You need to redefine the unnamed struct during &Configuration{}

package main

import "fmt"

type Configuration struct {
    Val   string
    Proxy struct {
        Address string
        Port    string
    }
}

func main() {

    c := &Configuration{
        Val: "test",
        Proxy: struct {
            Address string
            Port    string
        }{
            Address: "127.0.0.1",
            Port:    "8080",
        },
    }
    fmt.Println(c)
}

Well, it is cool that nobody found the solution for now, but it looks like I have something for you. The bad news is that the dialog grabs focus in any case even if no inputs and links are inside. I use the dialog as a tooltip and definitely need focus stay in the original element. Here is my solution:

use option [autoOpen: false]

$toolTip.dialog("widget").css("visibility", "hidden"); 
$toolTip.dialog("open");
$toolTip.dialog("widget").css("visibility", "visible");

While the dialog invisible, the focus is not set anywhere and stay in the original place. It works for tooltips with just a plain text, but not tested for more functional dialogs where it may be important to have dialog visible on opening moment. Probably will work fine in any case.

I understand that the original post was just to avoid getting focus on the first element, but you can easily decide where the focus should be after the dialog is opened (after my code).

Tested in IE, FF and Chrome.

Hopefully this will help somebody.

In case the remote repository is not empty (this is the case if you are using IBM DevOps on hub.jazz.net) then you need to use the following sequence:

cd <localDir>
git init
git add -A .
git pull <url> master
git commit -m "message"
git remote add origin <url>
git push

EDIT 30th Jan 17: Please see comments below, make sure you are on the correct repo!

I wrote the following code to convert an image from sdcard to a Base64 encoded string to send as a JSON object.And it works great:

String filepath = "/sdcard/temp.png";
File imagefile = new File(filepath);
FileInputStream fis = null;
try {
    fis = new FileInputStream(imagefile);
    } catch (FileNotFoundException e) {
    e.printStackTrace();
}

Bitmap bm = BitmapFactory.decodeStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();  
bm.compress(Bitmap.CompressFormat.JPEG, 100 , baos);    
byte[] b = baos.toByteArray(); 
encImage = Base64.encodeToString(b, Base64.DEFAULT);

State machines are very simple in C if you use function pointers.

Basically you need 2 arrays - one for state function pointers and one for state transition rules. Every state function returns the code, you lookup state transition table by state and return code to find the next state and then just execute it.

int entry_state(void);
int foo_state(void);
int bar_state(void);
int exit_state(void);

/* array and enum below must be in sync! */
int (* state[])(void) = { entry_state, foo_state, bar_state, exit_state};
enum state_codes { entry, foo, bar, end};

enum ret_codes { ok, fail, repeat};
struct transition {
    enum state_codes src_state;
    enum ret_codes   ret_code;
    enum state_codes dst_state;
};
/* transitions from end state aren't needed */
struct transition state_transitions[] = {
    {entry, ok,     foo},
    {entry, fail,   end},
    {foo,   ok,     bar},
    {foo,   fail,   end},
    {foo,   repeat, foo},
    {bar,   ok,     end},
    {bar,   fail,   end},
    {bar,   repeat, foo}};

#define EXIT_STATE end
#define ENTRY_STATE entry

int main(int argc, char *argv[]) {
    enum state_codes cur_state = ENTRY_STATE;
    enum ret_codes rc;
    int (* state_fun)(void);

    for (;;) {
        state_fun = state[cur_state];
        rc = state_fun();
        if (EXIT_STATE == cur_state)
            break;
        cur_state = lookup_transitions(cur_state, rc);
    }

    return EXIT_SUCCESS;
}

I don't put lookup_transitions() function as it is trivial.

That's the way I do state machines for years.

Since my edit to Mike G's answer to modernize the code was rejected 3 to 2 as

This edit was intended to address the author of the post and makes no sense as an edit. It should have been written as a comment or an answer

I'm reposting my edit as a separate answer here. This edit removes the JSONRepresentation dependency with NSJSONSerialization as Rob's comment with 15 upvotes suggests.

    NSArray *objects = [NSArray arrayWithObjects:[[NSUserDefaults standardUserDefaults]valueForKey:@"StoreNickName"],
      [[UIDevice currentDevice] uniqueIdentifier], [dict objectForKey:@"user_question"],     nil];
    NSArray *keys = [NSArray arrayWithObjects:@"nick_name", @"UDID", @"user_question", nil];
    NSDictionary *questionDict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

    NSDictionary *jsonDict = [NSDictionary dictionaryWithObject:questionDict forKey:@"question"];

    NSLog(@"jsonRequest is %@", jsonRequest);

    NSURL *url = [NSURL URLWithString:@"https://xxxxxxx.com/questions"];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
                 cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];


    NSData *requestData = [NSJSONSerialization dataWithJSONObject:dict options:0 error:nil]; //TODO handle error

    [request setHTTPMethod:@"POST"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
    [request setHTTPBody: requestData];

    NSURLConnection *connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
    if (connection) {
     receivedData = [[NSMutableData data] retain];
    }

The receivedData is then handled by:

NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
    NSDictionary *question = [jsonDict objectForKey:@"question"];

I'm going to make a summary of the proposed solutions and the one that helped me!

After reading this bug report: bug in the way NetBeans 6.8 creates the jar for a Java Library Project.

1. Create a manifest.mf file in my project root

2. Edit manifest.mf. Mine looked something like this:

   Manifest-Version: 1.0
   Ant-Version: Apache Ant 1.7.1
   Created-By: 16.3-b01 (Sun Microsystems Inc.)
   Main-Class: com.example.MainClass
   Class-Path: lib/lib1.jar lib/lib2.jar
   

3. Open file /nbproject/project.properties

4. Add line

   manifest.file=manifest.mf

5. Clean + Build of project

Now the .jar is successfully build.

Thank you very much vkraemer

I'm resurrecting the dead here, but because a range can be defined as "A:A", using a for each loop ends up with a potential infinite loop. The solution, as far as I know, is to use the Do Until loop.

Do Until Selection.Value = ""
  Rem Do things here...
Loop

Simply pass the BSTR directly to the wstring constructor, it is compatible with a wchar_t*:

BSTR btest = SysAllocString(L"Test");
assert(btest != NULL);
std::wstring wtest(btest);
assert(0 == wcscmp(wtest.c_str(), btest));

Converting BSTR to std::string requires a conversion to char* first. That's lossy since BSTR stores a utf-16 encoded Unicode string. Unless you want to encode in utf-8. You'll find helper methods to do this, as well as manipulate the resulting string, in the ICU library.

A common PyTorch convention is to save models using either a .pt or .pth file extension.

Save/Load Entire Model Save:

path = "username/directory/lstmmodelgpu.pth"
torch.save(trainer, path)

Load:

Model class must be defined somewhere

model = torch.load(PATH)
model.eval()

If the table has an ID:

const tableObject = document.getElementById(tableId);
const rowCount = tableObject[1].childElementCount;

If the table has a Class:

const tableObject = document.getElementsByClassName(tableClass);
const rowCount = tableObject[1].childElementCount;

If the table has a Name:

const tableObject = document.getElementsByTagName('table');
const rowCount = tableObject[1].childElementCount;

Note: index 1 represents <tbody> tag

If you look in your installation's bin directory you will see catalina.sh or .bat scripts. If you look in these you will see that they run a setenv.sh or setenv.bat script respectively, if it exists, to set environment variables. The relevant environment variables are described in the comments at the top of catalina.sh/bat. To use them create, for example, a file $CATALINA_HOME/bin/setenv.sh with contents

export JAVA_OPTS="-server -Xmx512m"

For Windows you will need, in setenv.bat, something like

set JAVA_OPTS=-server -Xmx768m

Original answer here

After you run startup.bat, you can easily confirm the correct settings have been applied provided you have turned @echo on somewhere in your catatlina.bat file (a good place could be immediately after echo Using CLASSPATH: "%CLASSPATH%"):

i would recommend Modern UI for WPF .

It has a very active maintainer it is awesome and free!

I'm currently porting some projects to MUI, first (and meanwhile second) impression is just wow!

To see MUI in action you could download XAML Spy which is based on MUI.

EDIT: Using Modern UI for WPF a few months and i'm loving it!

Maybe you have run into this problem: net::ERR_INSECURE_RESPONSE

You need to check the encryption algorithms supported by your server. For example for apache you can configure the cipher suite this way: cipher suite.

Which version of chrome are you running and what is the server serving your APIs?

Internet options-->General Tab-->browsing History section.... click settings and then click "View objects". A list of your active X add on's are displayed in the windows folder that they are stored in. You can manipulate these files as you would any others. Simply delete the ones you want to uninstall and restart IE.

Use runlike from git repository https://github.com/lavie/runlike

To install runlike

pip install runlike

As it accept container id as an argument so to extract container id use following command

docker ps -a -q

You are good to use runlike to extract complete docker run command with following command

runlike <docker container ID>

You need to add the source from where you're loading the data.

For Example:

$("#step1Content").load("yourpage.html");

Hope It will help you.

You can use ContainsKey:

if (dict.ContainsKey(key)) { ... }

or TryGetValue:

dict.TryGetValue(key, out value);

Update: according to a comment the actual class here is not an IDictionary but a PhysicalAddressDictionary, so the methods are Contains and TryGetValue but they work in the same way.

Example usage:

PhysicalAddressEntry entry;
PhysicalAddressKey key = c.PhysicalAddresses[PhysicalAddressKey.Home].Street;
if (c.PhysicalAddresses.TryGetValue(key, out entry))
{
    row["HomeStreet"] = entry;
}

Update 2: here is the working code (compiled by question asker)

PhysicalAddressEntry entry;
PhysicalAddressKey key = PhysicalAddressKey.Home;
if (c.PhysicalAddresses.TryGetValue(key, out entry))
{
    if (entry.Street != null)
    {
        row["HomeStreet"] = entry.Street.ToString();
    }
}

...with the inner conditional repeated as necessary for each key required. The TryGetValue is only done once per PhysicalAddressKey (Home, Work, etc).

Here is a everything you need to know about whitespace in regular expressions:

• [[:blank:]] Space or tab only
• [[:space:]] Whitespace
• \s Any whitespace character
• \v Vertical whitespace
• \h Horizontal whitespace
• x Ignore whitespace

You need to be at MySQL version 5.6.4 or later to declare columns with fractional-second time datatypes. Not sure you have the right version? Try SELECT NOW(3). If you get an error, you don't have the right version.

For example, DATETIME(3) will give you millisecond resolution in your timestamps, and TIMESTAMP(6) will give you microsecond resolution on a *nix-style timestamp.

Read this: https://dev.mysql.com/doc/refman/8.0/en/fractional-seconds.html

NOW(3) will give you the present time from your MySQL server's operating system with millisecond precision.

If you have a number of milliseconds since the Unix epoch, try this to get a DATETIME(3) value

FROM_UNIXTIME(ms * 0.001)

Javascript timestamps, for example, are represented in milliseconds since the Unix epoch.

(Notice that MySQL internal fractional arithmetic, like * 0.001, is always handled as IEEE754 double precision floating point, so it's unlikely you'll lose precision before the Sun becomes a white dwarf star.)

If you're using an older version of MySQL and you need subsecond time precision, your best path is to upgrade. Anything else will force you into doing messy workarounds.

If, for some reason you can't upgrade, you could consider using BIGINT or DOUBLE columns to store Javascript timestamps as if they were numbers. FROM_UNIXTIME(col * 0.001) will still work OK. If you need the current time to store in such a column, you could use UNIX_TIMESTAMP() * 1000

Just use line-clamp for the browsers that support it(most modern browsers) and fall back to 1 line for older.

  .text {
    white-space: nowrap;
    text-overflow: ellipsis;
    overflow: hidden;


    @supports (-webkit-line-clamp: 2) {
      overflow: hidden;
      text-overflow: ellipsis;
      white-space: initial;
      display: -webkit-box;
      -webkit-line-clamp: 2;
      -webkit-box-orient: vertical;
    }
  }

First of all, thanks for guiding me and closing this issue. I found a way to fix this issue from your discussions. Yeah, Let's come to the point. The thing is I'm Using GoogleMapHelper v3 helper in CakePHP3. When i tried to open bootstrap modal popup, I got struck with the grey box issue over the map. It's been extended for 2 days. Finally i got a fix over this.

We need to Update the GoogleMapHelper to fix the issue

Need to add the below script in setCenterMap function

google.maps.event.trigger({$id}, \"resize\");

And need the include below code in JavaScript

google.maps.event.addListenerOnce({$id}, 'idle', function(){
   setCenterMap(new google.maps.LatLng({$this->defaultLatitude}, 
   {$this->defaultLongitude}));
});

In case you want to remove timestamps from existing model, as mentioned before, place this in your Model:

public $timestamps = false;

Also create a migration with following code in the up() method and run it:

Schema::table('your_model_table', function (Blueprint $table) {
    $table->dropTimestamps();
});

You can use $table->timestamps() in your down() method to allow rolling back.

I know this has already been answered, but I wanted to share a potentially better looking way to call Popen via the use of from x import x and functions:

from subprocess import PIPE, Popen


def cmdline(command):
    process = Popen(
        args=command,
        stdout=PIPE,
        shell=True
    )
    return process.communicate()[0]

print cmdline("cat /etc/services")
print cmdline('ls')
print cmdline('rpm -qa | grep "php"')
print cmdline('nslookup google.com')

i found out the best way to refresh your Fragment when data change

if you have a button "search", you have to initialize your ARRAY list inside the button

mSearchBtn.setOnClickListener(new View.OnClickListener() {

@Override public void onClick(View v) {

mList = new ArrayList<Node>();

firebaseSearchQuery.addValueEventListener(new ValueEventListener() {
  @Override
  public void onDataChange(DataSnapshot dataSnapshot) {


      for (DataSnapshot dataSnapshot1 : dataSnapshot.getChildren()) {

        Node p = dataSnapshot1.getValue(Node .class);
        mList.add(p);
      }
      YourAdapter = new NodeAdapter(getActivity(), mList);
      mRecyclerView.setAdapter(YourAdapter );

    }

BIRT works pretty well.

According to Dangerously Set innerHTML,

Improper use of the innerHTML can open you up to a cross-site scripting (XSS) attack. Sanitizing user input for display is notoriously error-prone, and failure to properly sanitize is one of the leading causes of web vulnerabilities on the internet.

Our design philosophy is that it should be "easy" to make things safe, and developers should explicitly state their intent when performing “unsafe” operations. The prop name dangerouslySetInnerHTML is intentionally chosen to be frightening, and the prop value (an object instead of a string) can be used to indicate sanitized data.

After fully understanding the security ramifications and properly sanitizing the data, create a new object containing only the key __html and your sanitized data as the value. Here is an example using the JSX syntax:

function createMarkup() {
    return {
       __html: 'First · Second'    };
 }; 

<div dangerouslySetInnerHTML={createMarkup()} /> 

Read more about it using below link:

documentation: React DOM Elements - dangerouslySetInnerHTML.

For current ActiveRecord (4.2.4+) there is a method to_hash on the Result object that returns an array of hashes. You can then map over it and convert to symbolized hashes:

# Get an array of hashes representing the result (column => value):
result.to_hash
# => [{"id" => 1, "title" => "title_1", "body" => "body_1"},
      {"id" => 2, "title" => "title_2", "body" => "body_2"},
      ...
     ]

result.to_hash.map(&:symbolize_keys)
# => [{:id => 1, :title => "title_1", :body => "body_1"},
      {:id => 2, :title => "title_2", :body => "body_2"},
      ...
     ]

See the ActiveRecord::Result docs for more info.

you have already forwarded the response in catch block:

RequestDispatcher dd = request.getRequestDispatcher("error.jsp");

dd.forward(request, response);

so, you can not again call the :

response.sendRedirect("usertaskpage.jsp");

because it is already forwarded (committed).

So what you can do is: keep a string to assign where you need to forward the response.

    String page = "";
    try {

    } catch (Exception e) {
      page = "error.jsp";
    } finally {
      page = "usertaskpage.jsp";
    }

RequestDispatcher dd=request.getRequestDispatcher(page);
dd.forward(request, response);

This Bootstrap listener is to start up and shut down Spring's root WebApplicationContext. As a web application can have multiple dispatcher servlet and each having its own application context containing controllers, view resolver, handler mappings etc But you might want to have service beans, DAO beans in root application context and want to use in all child application context(application context created by dispatcher servlets).

2nd use of this listener is when you want to use spring security.

In SSMS in the Object Explorer, right click on the database, right-click and pick "Tasks" and then "Generate Scripts".

This will allow you to generate scripts for a single or all tables, and one of the options is "Script Data". If you set that to TRUE, the wizard will generate a script with INSERT INTO () statement for your data.

If using 2008 R2 or 2012 it is called something else, see screenshot below this one

2008 R2 or later eg 2012

Select "Types of Data to Script" which can be "Data Only", "Schema and Data" or "Schema Only" - the default).

And then there's a "SSMS Addin" Package on Codeplex (including source) which promises pretty much the same functionality and a few more (like quick find etc.)

I am posting my answer because I suspect there might be someone out there for whom the above solutions might not have worked.

So, you are getting a warning,

WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server: (project name)' did not find a matching property.

Rather than disabling this warning by checking that option in Server configuration (I did try that) I would suggest you do this:

1. First close all the existing projects by right clicking in Project explorer.
2. Remove all the projects already synchronized with the server.
3. Remove the server and redeploy it.
4. Create a new dynamic project, do nothing yet just try running this on the server.
5. Check the console, do you get the warning now. (My case I didn't get any).
   This means that something is wrong with your project not with eclipse or the server.
6. Now restart the server. Don't run any app yet.
   You probably know that the Tomcat container loads up context of all the synchronized apps at the start.
7. It will load context of any already synchronized app.
8. Here is the catch, if there is really something wrong in your project it will show the stack trace of the exceptions.Look carefully and you will find where is the bug in your app.

Now if you successfully found that there is a bug in your app, the probable place would be look for a web.xml file which the container uses for loading the app. In my case I had misspelled a name in servlet mapping which made me debug meaninglessly for 3 hours. Your problem might be someplace else.

And another thing, if you have many apps synchronized with the server,there is a possibility some other app's context might be the source of problem. Try debugging one by one.

There are a variety of ways of achieving this goal, some are clearer than others. For each of my examples, 'True' means that the string passed is valid, 'False' means it contains invalid characters.

First of all, there's the naive approach:

import string
allowed = string.letters + string.digits + '_' + '-'

def check_naive(mystring):
    return all(c in allowed for c in mystring)

Then there's use of a regular expression, you can do this with re.match(). Note that '-' has to be at the end of the [] otherwise it will be used as a 'range' delimiter. Also note the $ which means 'end of string'. Other answers noted in this question use a special character class, '\w', I always prefer using an explicit character class range using [] because it is easier to understand without having to look up a quick reference guide, and easier to special-case.

import re
CHECK_RE = re.compile('[a-zA-Z0-9_-]+$')
def check_re(mystring):
    return CHECK_RE.match(mystring)

Another solution noted that you can do an inverse match with regular expressions, I've included that here now. Note that [^...] inverts the character class because the ^ is used:

CHECK_INV_RE = re.compile('[^a-zA-Z0-9_-]')
def check_inv_re(mystring):
   return not CHECK_INV_RE.search(mystring)

You can also do something tricky with the 'set' object. Have a look at this example, which removes from the original string all the characters that are allowed, leaving us with a set containing either a) nothing, or b) the offending characters from the string:

def check_set(mystring):
    return not set(mystring) - set(allowed)

Make use of Arrow functions it improves the readability of code. No need to return anything in API.fetchComments, Api call is asynchronous when the request is completed then will get the response, there you have to just dispatch type and data.

Below code does the same job by making use of Arrow functions.

export const bindComments = postId => {
  return dispatch => {
    API.fetchComments(postId).then(comments => {
      dispatch({
        type: BIND_COMMENTS,
        comments,
        postId
      });
    });
  };
};

You can get the best of both worlds. It is possible to use ExternalProject to download the gtest source and then use add_subdirectory() to add it to your build. This has the following advantages:

• gtest is built as part of your main build, so it uses the same compiler flags, etc. and hence avoids problems like the ones described in the question.
• There's no need to add the gtest sources to your own source tree.

Used in the normal way, ExternalProject won't do the download and unpacking at configure time (i.e. when CMake is run), but you can get it to do so with just a little bit of work. I've written a blog post on how to do this which also includes a generalised implementation which works for any external project which uses CMake as its build system, not just gtest. You can find them here:

• https://crascit.com/2015/07/25/cmake-gtest/
• https://github.com/Crascit/DownloadProject

Update: This approach is now also part of the googletest documentation.

Here is another good explanation from the book:

As for the difference between SCOPE_IDENTITY and @@IDENTITY, suppose that you have a stored procedure P1 with three statements:
- An INSERT that generates a new identity value
- A call to a stored procedure P2 that also has an INSERT statement that generates a new identity value
- A statement that queries the functions SCOPE_IDENTITY and @@IDENTITY The SCOPE_IDENTITY function will return the value generated by P1 (same session and scope). The @@IDENTITY function will return the value generated by P2 (same session irrespective of scope).

Here's a random idea that utilizes (abuses?) the data model (Py3 link).

class Counter(object):
    def __init__(self, val):
        self.val = val

    def __nonzero__(self):
        self.val -= 1
        return self.val >= 0
    __bool__ = __nonzero__  # Alias to Py3 name to make code work unchanged on Py2 and Py3

x = Counter(5)
while x:
    # Do something
    pass

I wonder if there is something like this in the standard libraries?

A little addition to ohad navon's answer.

If the center of the element belongs to the another element we won't find it.

So to make sure that one of the points of the element is found to be visible

function isElementVisible(elem) {
    if (!(elem instanceof Element)) throw Error('DomUtil: elem is not an element.');
    const style = getComputedStyle(elem);
    if (style.display === 'none') return false;
    if (style.visibility !== 'visible') return false;
    if (style.opacity === 0) return false;
    if (elem.offsetWidth + elem.offsetHeight + elem.getBoundingClientRect().height +
        elem.getBoundingClientRect().width === 0) {
        return false;
    }
    var elementPoints = {
        'center': {
            x: elem.getBoundingClientRect().left + elem.offsetWidth / 2,
            y: elem.getBoundingClientRect().top + elem.offsetHeight / 2
        },
        'top-left': {
            x: elem.getBoundingClientRect().left,
            y: elem.getBoundingClientRect().top
        },
        'top-right': {
            x: elem.getBoundingClientRect().right,
            y: elem.getBoundingClientRect().top
        },
        'bottom-left': {
            x: elem.getBoundingClientRect().left,
            y: elem.getBoundingClientRect().bottom
        },
        'bottom-right': {
            x: elem.getBoundingClientRect().right,
            y: elem.getBoundingClientRect().bottom
        }
    }

    for(index in elementPoints) {
        var point = elementPoints[index];
        if (point.x < 0) return false;
        if (point.x > (document.documentElement.clientWidth || window.innerWidth)) return false;
        if (point.y < 0) return false;
        if (point.y > (document.documentElement.clientHeight || window.innerHeight)) return false;
        let pointContainer = document.elementFromPoint(point.x, point.y);
        if (pointContainer !== null) {
            do {
                if (pointContainer === elem) return true;
            } while (pointContainer = pointContainer.parentNode);
        }
    }
    return false;
}

It's very simple,

just run the following commands

sudo a2enmod ssl

sudo service apache2 restart

sudo a2ensite default-ssl.conf

That's it, you are done.

If you want to force SSL (to use https always), edit the file:

sudo nano /etc/apache2/sites-available/000-default.conf

and add this one line

<VirtualHost *:80>
        . . .

        Redirect "/" "https://your_domain_or_IP/"

        . . .
</VirtualHost>

then restart again

sudo service apache2 restart

The short answer is yes, yes there is a way to get around mysql_real_escape_string(). #For Very OBSCURE EDGE CASES!!!

The long answer isn't so easy. It's based off an attack demonstrated here.

The Attack

So, let's start off by showing the attack...

mysql_query('SET NAMES gbk');
$var = mysql_real_escape_string("\xbf\x27 OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

In certain circumstances, that will return more than 1 row. Let's dissect what's going on here:

1. Selecting a Character Set

   mysql_query('SET NAMES gbk');
   

   For this attack to work, we need the encoding that the server's expecting on the connection both to encode ' as in ASCII i.e. 0x27 and to have some character whose final byte is an ASCII \ i.e. 0x5c. As it turns out, there are 5 such encodings supported in MySQL 5.6 by default: big5, cp932, gb2312, gbk and sjis. We'll select gbk here.

   Now, it's very important to note the use of SET NAMES here. This sets the character set ON THE SERVER. If we used the call to the C API function mysql_set_charset(), we'd be fine (on MySQL releases since 2006). But more on why in a minute...

2. The Payload

   The payload we're going to use for this injection starts with the byte sequence 0xbf27. In gbk, that's an invalid multibyte character; in latin1, it's the string ¿'. Note that in latin1 and gbk, 0x27 on its own is a literal ' character.

   We have chosen this payload because, if we called addslashes() on it, we'd insert an ASCII \ i.e. 0x5c, before the ' character. So we'd wind up with 0xbf5c27, which in gbk is a two character sequence: 0xbf5c followed by 0x27. Or in other words, a valid character followed by an unescaped '. But we're not using addslashes(). So on to the next step...

3. mysql_real_escape_string()

   The C API call to mysql_real_escape_string() differs from addslashes() in that it knows the connection character set. So it can perform the escaping properly for the character set that the server is expecting. However, up to this point, the client thinks that we're still using latin1 for the connection, because we never told it otherwise. We did tell the server we're using gbk, but the client still thinks it's latin1.

   Therefore the call to mysql_real_escape_string() inserts the backslash, and we have a free hanging ' character in our "escaped" content! In fact, if we were to look at $var in the gbk character set, we'd see:

   ?' OR 1=1 /*

   Which is exactly what the attack requires.

4. The Query

   This part is just a formality, but here's the rendered query:

   SELECT * FROM test WHERE name = '?' OR 1=1 /*' LIMIT 1
   

Congratulations, you just successfully attacked a program using mysql_real_escape_string()...

The Bad

It gets worse. PDO defaults to emulating prepared statements with MySQL. That means that on the client side, it basically does a sprintf through mysql_real_escape_string() (in the C library), which means the following will result in a successful injection:

$pdo->query('SET NAMES gbk');
$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));

Now, it's worth noting that you can prevent this by disabling emulated prepared statements:

$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

This will usually result in a true prepared statement (i.e. the data being sent over in a separate packet from the query). However, be aware that PDO will silently fallback to emulating statements that MySQL can't prepare natively: those that it can are listed in the manual, but beware to select the appropriate server version).

The Ugly

I said at the very beginning that we could have prevented all of this if we had used mysql_set_charset('gbk') instead of SET NAMES gbk. And that's true provided you are using a MySQL release since 2006.

If you're using an earlier MySQL release, then a bug in mysql_real_escape_string() meant that invalid multibyte characters such as those in our payload were treated as single bytes for escaping purposes even if the client had been correctly informed of the connection encoding and so this attack would still succeed. The bug was fixed in MySQL 4.1.20, 5.0.22 and 5.1.11.

But the worst part is that PDO didn't expose the C API for mysql_set_charset() until 5.3.6, so in prior versions it cannot prevent this attack for every possible command! It's now exposed as a DSN parameter.

The Saving Grace

As we said at the outset, for this attack to work the database connection must be encoded using a vulnerable character set. utf8mb4 is not vulnerable and yet can support every Unicode character: so you could elect to use that instead—but it has only been available since MySQL 5.5.3. An alternative is utf8, which is also not vulnerable and can support the whole of the Unicode Basic Multilingual Plane.

Alternatively, you can enable the NO_BACKSLASH_ESCAPES SQL mode, which (amongst other things) alters the operation of mysql_real_escape_string(). With this mode enabled, 0x27 will be replaced with 0x2727 rather than 0x5c27 and thus the escaping process cannot create valid characters in any of the vulnerable encodings where they did not exist previously (i.e. 0xbf27 is still 0xbf27 etc.)—so the server will still reject the string as invalid. However, see @eggyal's answer for a different vulnerability that can arise from using this SQL mode.

Safe Examples

The following examples are safe:

mysql_query('SET NAMES utf8');
$var = mysql_real_escape_string("\xbf\x27 OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

Because the server's expecting utf8...

mysql_set_charset('gbk');
$var = mysql_real_escape_string("\xbf\x27 OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

Because we've properly set the character set so the client and the server match.

$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$pdo->query('SET NAMES gbk');
$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));

Because we've turned off emulated prepared statements.

$pdo = new PDO('mysql:host=localhost;dbname=testdb;charset=gbk', $user, $password);
$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));

Because we've set the character set properly.

$mysqli->query('SET NAMES gbk');
$stmt = $mysqli->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$param = "\xbf\x27 OR 1=1 /*";
$stmt->bind_param('s', $param);
$stmt->execute();

Because MySQLi does true prepared statements all the time.

Wrapping Up

If you:

• Use Modern Versions of MySQL (late 5.1, all 5.5, 5.6, etc) AND mysql_set_charset() / $mysqli->set_charset() / PDO's DSN charset parameter (in PHP = 5.3.6)

OR

• Don't use a vulnerable character set for connection encoding (you only use utf8 / latin1 / ascii / etc)

You're 100% safe.

Otherwise, you're vulnerable even though you're using mysql_real_escape_string()...

are you sure you told it to expect the exception?

for newer junit (>= 4.7), you can use something like (from here)

@Rule
public ExpectedException exception = ExpectedException.none();

@Test
public void testRodneCisloRok(){
    exception.expect(IllegalArgumentException.class);
    exception.expectMessage("error1");
    new RodneCislo("891415",dopocitej("891415"));
}

and for older junit, this:

@Test(expected = ArithmeticException.class)  
public void divisionWithException() {  
  int i = 1/0;
}

DECLARE @CarList nvarchar(max);
SET @CarList = N'';
SELECT @CarList+=CarName+N','
FROM dbo.CARS;
SELECT LEFT(@CarList,LEN(@CarList)-1);

Thanks are due to whoever on SO showed me the use of accumulating data during a query.

I think your problem is that you are not using good OO design for your player and enemies. Create two classes:

public class Player
{
    int X;
    int Y;
    int Width;
    int Height;

    // Getters and Setters
}

public class Enemy
{
    int X;
    int Y;
    int Width;
    int Height;

    // Getters and Setters
}

Your Player should have X,Y,Width,and Height variables.

Your enemies should as well.

In your game loop, do something like this (C#):

foreach (Enemy e in EnemyCollection)
{
    Rectangle r = new Rectangle(e.X,e.Y,e.Width,e.Height);
    Rectangle p = new Rectangle(player.X,player.Y,player.Width,player.Height);

    // Assuming there is an intersect method, otherwise just handcompare the values
    if (r.Intersects(p))
    {
       // A Collision!
       // we know which enemy (e), so we can call e.DoCollision();
       e.DoCollision();
    }
}

To speed things up, don't bother checking if the enemies coords are offscreen.
