I am looking at general practices (such as versioning your system), tools and I will give examples of the ones I am using or will be implementing shortly.
------------
**Caching:**
* APC
* MemCache
* .htaccess
**Compression:**
* GZip
* JSMin
* Custom CSS Compressor
**Database:**
* MySQL
**Dependency Management:**
* HeadJS
**Frameworks:**
* jQuery [have thought about using Javelin]
* [No PHP Framework due to performance hit]
**Profiling:**
* XHProf (PHP)
**Testing:**
* PHPUnit
* Selenium
* QUnit
**Version Control:**
* GitHub
-----------
The reason I am asking is because I keep coming across more technologies or things that should be done for systems that I am simply unaware of. Here is a list of a few other technologies that I have looked at but don't quite seem to help. I am looking at things to optimize development and provide a better and importantly **faster** system.
* Pagelets / BigPipe (From Facebook: Not available to the public and open source ones don't seem to have that great of a benefit)
* Haste (From Facebook: Not available to the public - CSS/JS Dependency Management)
* XHP (Major performance hit)
* SVN (More complicated than GitHub)
If there are many missing sections above (Testing only recently has entered our system scopes), please let me know. | php | technologies | system-design | null | null | 06/03/2011 04:04:05 | not a real question | PHP - System Practices, Technologies & Tools

Is there a high-concurrency method for this query that will allow it to maintain performance while still avoiding the insertion of data that already exists?

I want the receiving servers to receive the message at exact same time / or micro second level.
What is the best strategy that I can use that will effectively allow the receiving socket to receive it at the exact same time. Naturally my requirements are extremely time sensitive.
I'm basing some of my research / design on the two following articles:
- http://onestepback.org/index.cgi/Tech/Ruby/MulticastingInRuby.red
- http://www.tutorialspoint.com/ruby/ruby_socket_programming.htm
Now currently I'm working on a TCP solution and not UDP because of it's guaranteed delivery. Also, was going to stand up ready connected connections to all outbound ports. Then iterate over each connection and send the minimal packet of data.
Recently, I'm looking at multicasting now and possibly reverting back to a UDP approach with a return a passive response, but ensure the message was sent back either via UDP / TCP.
Note - The new guy syndrome here with sockets.
Is it better to just use UDP and send a broad packet spam to the entire subnet without guaranteed immediate delivery? | ruby-on-rails | ruby | sockets | null | null | null | open | Sending data to multiple sockets at exact same time

Hopefully somebody here can help me out!
In the web project, within the ClientBin directory I have a directory called Images which contains a png file.
In the MainPage.xaml file, I can create an Image object, call it mainImage and then in the code behind use this in the constructor:
BitmapImage src = new BitmapImage(new Uri("Images/myImage.png", UriKind.Relative));
mainImage.SetValue(Image.SourceProperty, src);
This all works fine, however when I create a UserControl with the same functionality and then create an instance of that control on the MainPage.xaml the application runs but I get no images. Why is this?
I will also point out that the new user control has been created in a Controls folder and so has a different namespace (solutionName.Controls or whatever)
Any help would be great, and if you need any more info please ask (tried to keep it brief)

I'll try to distill what I'm trying to do to the simplest possible case. I have:
struct Integer {
int value;
};
BOOST_FUSION_ADAPT_STRUCT(Integer, (int, value))
Later, inside of a grammar struct, I have the following member variable:
qi::rule<Iterator, Integer> integer;
which I am defining with
integer = qi::int_;
When I try to actually parse an integer, however, using
qi::phrase_parse(iter, end, g, space, myInteger);
`myInteger.value` is always uninitialized after a successful parse.
Similarly, I have tried the following definitions (obviously the ones that don't compile are wrong):
integer = qi::int_[qi::_val = qi::_1]; //compiles, uninitialized value
integer = qi::int_[qi::_r1 = qi::_1]; //doesn't compile
integer = qi::int_[phoenix::bind(&Integer::value, qi::_val) = qi::_1]; //doesn't
integer = qi::int_[phoenix::at_c<0>(qi::_val) = qi::_1]; //doesn't
Clearly I am misunderstanding something about Spirit, Phoenix, or something else. My understanding is that `qi::_1` is the first attribute of `qi::int_`, here, and should represent the parsed integer, when the part in the square brackets gets executed as a function object. I am then assuming that the function object will take the enclosing `integer` attribute `qi::_val` and try and assign the parsed integer to it. My guess was that because of my `BOOST_FUSION_ADAPT_STRUCT` call, the two would be compatible, and that certainly seems to be the case from a static analysis perspective, but the data is not being preserved.

I have a table

`uid` int(10) unsigned NOT NULL default '0',
`value` text,
PRIMARY KEY (`uid`,`fid`),
KEY `fid` (`fid`)

The point of this table is to store profile information on a user.

fid | uid | value
__________________

</pre>
Note:
<pre>
'fid' of '1' represents the first name
'fid' of '11' represents the last name
'uid' is a users id within the site.
</pre>
What I am trying to achieve is to bring back all uid's that satisfy the condition of first name like 'S%' and last name like 'D%'.
The reason i need this is because i have an autocomplete search box for users on the site.
So if i type 'S' in the search box i will see list of all users that begin with the letter 'S', if i now type a whitespace and 'D' i should now be able to see the list of users who match both conditions.
Does anyone have any idea how this can be accomplished?
Thanks in advance.

I was given the above program and was asked to figure out the problems in the above code.
below was my answer
- function declaration is wrong.the
return type should be `char **`
- syntax of `printf` is wrong
- `arr` scope is limited to the function `fun1`
then
***Interviewer*** : what would be your solution to the problem?
***Me***: you need to make the arr variable as global and fix the remaining issues mentioned above.
***Interviewer***: Dont you think global variables are dangerous?
***Me***: Yes ofcourse,since we cannot say where it is being accessed in which functions and sometimes it gets almost impossible to find which function has changed the value
***Ineterviewer*** :give me a solution without a global variable

Now this is what i am trying to accomplish:
When I send message then that message should only be visible to the another user of that app, who is in my friend list. Similarly when I want to share any bucket or folders, only friend or group of friend can see the content in the shared folder.
I have tried to use IAM to create users and then assign policy for S3 folder or SQS/SNS. But with IAM there is upper limit for the number of users around 5000, but I want to scale this number to over 1 million. Is this possible?
I also tried to use TVM for it, but in TVM all the tokens created are having the same policy, based on the parent IAM user. Is there any way I can differentiate between 2 tokens of TVM and set a policy to differentiate them, such that both tokens can not access the resources of each other, until given a permission?
Any Other thoughts or different approach on this app will be welcome.
Thanks

I have recently started a new project at home. I wont bore you with details as they dont matter. Point is, I thought I would take the time to look into all this hype about GIT. A lot of the libraries I end up using seem to be on GitHub and so I thought it would be beneficial to learn it.
So I done some reading. Lots of blog articles, lots of Stackoverflow questions. Also adopted GIT in my most recent project at home just to get a feel for it. Now before I get flamed for poo-poo'ing GIT, all my considerations for this question are for **changing from CVS to GIT**. That is to say, we already have a project up and running with a stable HEAD and 3-4 branches for different clients and configurations that a small team of 3-6 people are using without too many issues. If you are sitting at square 1 waiting to start a project and wondering what source control system to use, I understand entirely why you would go for GIT.
With that bit out the way, let me actually ask my question. I have been asked to see if there are any real business advantages to moving from CVS to GIT. After a few weeks of reading, I still cannot really find anything that would make a real compelling case to actually make the switch. As I say I have been doing a lot of reading and for the most part, GIT-Fans seem to be pushing it based on 3 main advantages; speed, easy-branching and a handful of features that SVN just doesn't offer (partial file commits, stging ect). After reading in relative detail about each of these issues, i'm still left thinking 'so what?'
**Speed:**
I'm not saying the following links is a particularly comprehensive argument for switching to GIT but it highlight all the points i'm going to make in this post and its open now on a tab so its easy to link.
http://thinkvitamin.com/code/why-you-should-switch-from-subversion-to-git/
So this guy does a few crude benchmarks of creating a branch and switching to it in both GIT and SVN. He concludes that it takes 1/3rd of a second in GIT and 13 seconds in SVN. Now I don't know what kind of a team you readers work in but, mine can certainly spare 13 seconds every now and again to create a branch if need be. We have a pretty fancy coffee machine here and that fails to produce a cup in less than 13 seconds so this is hardly a game-changer. I appreciate he details that branching is quite a lightweight process so lets consider **my** use-case. I do a load of work during the day and commit the stable stuff in the evening before I go home. On a big commit, where I have added several hundred files as well as changed, moved and re-factored existing ones, CVS will of performed the commit before I can put my coat on and tidy my desk or wrapper and cups so GIT's super speed is not really selling it to me here.
**Easy branching:**
Again, referring to the above link he paints a picture of absolute hatred when using branches in SVN/CVS. Surely people aren't finding it that difficult ? When I want to try out an idea, I right click my project node in Eclipse, select "Switch to different branch", select "new", type the name and i'm away, committing and updating without 'polluting the mainline' as CVS apparent does. Now, i'm not the only one that doesn't consider this process on-parr with rocket science surely !? Likewise, when I have decided that the new ideas in this branch are stable and good, I right click the project again, select "merge with another branch or version", select HEAD and wait my obligatory 13seconds and we are back in HEAD but with working changes implemented...happy days, all without GIT.
Yes, fair enough this process may not go as smoothly if someone has made a few changes to associated files in the mean time, but this only adds a few more right-clicks to the process where I have to tell the system which lines of the file to use and which to discard/move. I understand the process is the same with GIT so there is no real +/- here, just the same.
**Truly distributed**
The aforementioned post also details a scary scenario where you repository provider sustains a hard-disk corruption and you loose your online repository. He then goes on to detail that because GIT is has a local repository, this would be no more of an inconvenience than to simply push to a new / repaired server and your away again. Now I consider it standard practice for the first thing to do in the morning is check the repository for any changes made over-night and do an update/merge if needed so, should I go home tonight and find my repository has been burnt to the ground in the morning, I would of lost...well...nothing. I would create a new repo, commit my local files to the server, the other 5 employees would do the same, there would maybe be a bit of merge fuss but no more than there would of been had we of been committing our local changes to an already existing server and we are away once more. No big deal.
**GIT Staging**
Another feature touted as wonderful that you cannot achieve using SVN/CVS is staging where you 'craft your commit' to include on the files you want. This is apparently unachievable using SVN/CVS. May I introduce these people to change-sets ?
----
Now i'm not ignorant enough to think that I am the only person on the internet that is able to see through all these comparisons to see GIT as simply another version control system and really, nothing special. So I can only conclude that I must be missing or misunderstanding something and would appreciate others' input for this exact reason. I must present in a meeting in a little over a week, a case for moving from CVS to GIT and really, at this point I don't see there is one. I don't think GIT could bring anything beneficial to the table over CVS other than helping those that don't like leaving branches on CVS for the rest of the team to see. What's more, I see some real **disadvantages** in using GIT.
Lets reverse the idea of loosing a central repository. You have been working on 101 fancy new ideas over the weekend and been committing like a mad-man to your wonderfully fast, localised repository, excited by the idea of getting the new features reviewed and cleared to push up to the server. But wait, what's this? And irreversible BSOD error? An entire cup-o-coffee over your CPU ? Laptop stolen, lost, ran over ? All of these issues, while extremely annoying in an SVN setup would only result in me loosing a bit of tech, all my work would have been safely stored on the server each time I did a commit to my little test-branch. However, using GIT, all those changes were local and now, you may as well of watched TV all weekend because all that work, all those commits are now gone and the outside world has no record of it what-so-ever! Now all those little 13 second branch-times seem a little more appealing eh ?
What's more about this 'offline-mode' stuff. I can't remember the last time I was actually without an internet connection. Even walking the dog in the forest, if I absolutely **had** to do some work, I could commit to on line repository using edge / 3G signal, would take about 5mins sure, but I could if I wanted to. Has anyone actually ever been doing serious work without an internet connection of some description in the last...I don't know...3-5 years ?
Thank you for reading this wall of text and I look forward to hearing your views. While it does seem to me that it is a case of a community getting over-excited about a new, shiny technology, I actually do really like these newer features of GIT, I just don't think it creates a strong enough case to move from CVS to GIT in a functioning business environment. If someone could open my eyes in this respect, I would be eternally grateful. | git | svn | version-control | cvs | null | 04/19/2012 14:58:26 | not a real question | CVS to GIT seems silly.

After a few weeks of reading, I still cannot really find anything that would make a real compelling case to actually make the switch. As I say I have been doing a lot of reading and for the most part, GIT-Fans seem to be pushing it based on 3 main advantages; speed, easy-branching and a handful of features that SVN just doesn't offer (partial file commits, stging ect). After reading in relative detail about each of these issues, i'm still left thinking 'so what?'
**Speed:**
I'm not saying the following links is a particularly comprehensive argument for switching to GIT but it highlight all the points i'm going to make in this post and its open now on a tab so its easy to link.
http://thinkvitamin.com/code/why-you-should-switch-from-subversion-to-git/
So this guy does a few crude benchmarks of creating a branch and switching to it in both GIT and SVN. He concludes that it takes 1/3rd of a second in GIT and 13 seconds in SVN. Now I don't know what kind of a team you readers work in but, mine can certainly spare 13 seconds every now and again to create a branch if need be. We have a pretty fancy coffee machine here and that fails to produce a cup in less than 13 seconds so this is hardly a game-changer. I appreciate he details that branching is quite a lightweight process so lets consider **my** use-case. I do a load of work during the day and commit the stable stuff in the evening before I go home. On a big commit, where I have added several hundred files as well as changed, moved and re-factored existing ones, CVS will of performed the commit before I can put my coat on and tidy my desk or wrapper and cups so GIT's super speed is not really selling it to me here.
**Easy branching:**
Again, referring to the above link he paints a picture of absolute hatred when using branches in SVN/CVS. Surely people aren't finding it that difficult ? When I want to try out an idea, I right click my project node in Eclipse, select "Switch to different branch", select "new", type the name and i'm away, committing and updating without 'polluting the mainline' as CVS apparent does. Now, i'm not the only one that doesn't consider this process on-parr with rocket science surely !? Likewise, when I have decided that the new ideas in this branch are stable and good, I right click the project again, select "merge with another branch or version", select HEAD and wait my obligatory 13seconds and we are back in HEAD but with working changes implemented...happy days, all without GIT.
Yes, fair enough this process may not go as smoothly if someone has made a few changes to associated files in the mean time, but this only adds a few more right-clicks to the process where I have to tell the system which lines of the file to use and which to discard/move. I understand the process is the same with GIT so there is no real +/- here, just the same.
**Truly distributed**
The aforementioned post also details a scary scenario where you repository provider sustains a hard-disk corruption and you loose your online repository. He then goes on to detail that because GIT is has a local repository, this would be no more of an inconvenience than to simply push to a new / repaired server and your away again. Now I consider it standard practice for the first thing to do in the morning is check the repository for any changes made over-night and do an update/merge if needed so, should I go home tonight and find my repository has been burnt to the ground in the morning, I would of lost...well...nothing. I would create a new repo, commit my local files to the server, the other 5 employees would do the same, there would maybe be a bit of merge fuss but no more than there would of been had we of been committing our local changes to an already existing server and we are away once more. No big deal.
**GIT Staging**
Another feature touted as wonderful that you cannot achieve using SVN/CVS is staging where you 'craft your commit' to include on the files you want. This is apparently unachievable using SVN/CVS. May I introduce these people to change-sets ?
----
Now i'm not ignorant enough to think that I am the only person on the internet that is able to see through all these comparisons to see GIT as simply another version control system and really, nothing special. So I can only conclude that I must be missing or misunderstanding something and would appreciate others' input for this exact reason. I must present in a meeting in a little over a week, a case for moving from CVS to GIT and really, at this point I don't see there is one. I don't think GIT could bring anything beneficial to the table over CVS other than helping those that don't like leaving branches on CVS for the rest of the team to see. What's more, I see some real **disadvantages** in using GIT.
Lets reverse the idea of loosing a central repository. You have been working on 101 fancy new ideas over the weekend and been committing like a mad-man to your wonderfully fast, localised repository, excited by the idea of getting the new features reviewed and cleared to push up to the server. But wait, what's this? And irreversible BSOD error? An entire cup-o-coffee over your CPU ? Laptop stolen, lost, ran over ? All of these issues, while extremely annoying in an SVN setup would only result in me loosing a bit of tech, all my work would have been safely stored on the server each time I did a commit to my little test-branch. However, using GIT, all those changes were local and now, you may as well of watched TV all weekend because all that work, all those commits are now gone and the outside world has no record of it what-so-ever! Now all those little 13 second branch-times seem a little more appealing eh ?
What's more about this 'offline-mode' stuff. I can't remember the last time I was actually without an internet connection. Even walking the dog in the forest, if I absolutely **had** to do some work, I could commit to on line repository using edge / 3G signal, would take about 5mins sure, but I could if I wanted to. Has anyone actually ever been doing serious work without an internet connection of some description in the last...I don't know...3-5 years ?
Thank you for reading this wall of text and I look forward to hearing your views. While it does seem to me that it is a case of a community getting over-excited about a new, shiny technology, I actually do really like these newer features of GIT, I just don't think it creates a strong enough case to move from CVS to GIT in a functioning business environment. If someone could open my eyes in this respect, I would be eternally grateful. | 1 |

My goal is to share the majority of the rendering/gameplay/UI code between both platforms, and have an OS-specific wrapper that handles things like touch events, resources, networking, etc.
For the shared UI, I can either write my own system, or use an existing toolkit/framework. My UI will mostly consist of buttons, toolbars, possibly a simple menu system, tooltips/overlays, scroll views, and font rendering. These are my requirements:
- Skinnable - definitely necessary to provide my own image-based graphics to the buttons/toolbars/etc.
- Scalable - I will be targeting devices of varying screen resolutions and sizes, so something that allows you to build UI using dpi or percentages is a must
- Platform-independent - most UI toolkits out there, even when cross-platform, use OS-native rendering or widgets. Since this will run on both iOS and Android, I need something that defines its own widgets and renders to OpenGL directly.
Here are the frameworks I am aware of right now. I have not yet looked into any of them deeply, so opinions are welcome:
- Cocos2D-x
- NUI
- Clutter
- Crazy Eddie's GUI (CEGUI)
- MyGUI
- Gwen
So, what framework do you recommend, and why? Or do you recommend I just write a UI framework customized for my own game?
*Please no suggestions for alternate ways of coding the game - I'm invested in using C++ and OpenGL ES for various reasons, and I am already comfortable with using the Android NDK for native support on Android.* | android | c++ | ios | user-interface | opengl-es | 02/24/2012 01:47:19 | not constructive | What UI Framework to use for OpenGL game when sharing code between Android and iOS?

The protocol is really simple: client/server sends a string to the server/client and it takes the corresponding action - via a handler, i suppose - and replies OR NOT to the other side with another string. Strings can be three things: an acknowledgement, signalling one side that the other on is still alive; a pickled class containing a command, if going from the "client" to the "server", or a response, if going from the "server" to the "client"; and finally a "lock" command, that signals a side of the conversation that the other is working and no further questions should be asked until another lock packet is received.
I have been looking at the python's built in SocketServer.TCPServer, but it's way too low level, it does not easily support reconnection and the client has to use the socket interface, which i preferred to be encapsulated.
I then explored the twisted framework, particularly the LineOnlyReceiver protocol and server examples, but i found the initial learning curve to be too steep, the online documentation assuming a little too much knowledge and a general lack of examples and good documentation (except the 2005 O'reilly book, is this still valid?).
I then tryied the pyliblo library, which is perfect for the task, alas it is monodirectional, there is no way to "answer" a client, and i need the answer to be associated to the specific command.
So my question is: is there an existing framework/library/module that allows me to have a client object in the server, to read the commands from and send the replies to, and a server object in the client, to read the replies from and send the commands to, that i can use after a simple setup (client, the server address is host:port, server, you are listening on port X) having the underlying socket, reconnection engine and so on handled?
