I installed unbuntu on virtualbox. The problem I have is that the settings don't get saved. Everytime I restart the server, it takes me to the main menu. (language settings etc)
Is there high-level language out there for describing algorithms, that's geared towards specification, rather than implementation?
The idea would be to have a machine-readable archive of standard algorithms, with machine-readable annotations on trade-offs, and variants.
I'm thinking of something like CycL / OpenCyC, but for algorithms and programming patterns.
Hey guys
I'm very new to the whole programming - so far I only have experience with building websites, database etc.
I currently have a website where users can share their online purchases.
I want to build a widget that other websites can integrate on their site. Users should be able to insert their purchases directly through this widget without having to come to my website.
Thats the idea but I have no idea how to go about it - can anyone point me in the right direction.
Thanks
Modern keyboards have special multimedia keys, e.g. 'Pause/Play' or 'Open Web Browser'. Is it possible to write a program that "presses" these keys?
I would prefer solution in C, but I would accept a language agnostic solution, too.
I'm a blind student currently in a system admin/shell programming class. Although ssh works fine for executing commands like ls, pwd, etc editors do not work well with my screen reader and an ssh session. I was wondering if it is possible to mount a Linux folder over ssh so it appears as a windows drive? This way I could edit any files I needed to with accessible software and not have to constantly use SCP to send files back and fourth.
I'm looking for a complete list of security guidelines for programming and deploying PHP web sites and applications on an Apache (Linux) server. Basically, a "security check list" to run through before finishing a project. I.e.,
Cross Site Scripting
Cross Site Request Forgery
Sanitize form data that goes into database
Disable register globals and error reporting in custom php.ini
Upload files below web root
...(the list goes on)
I did some searching on the internet and in this forum, but couldn't find a comprehensive, succinct, and complete list of guidelines.
Thanks in advance.
I know very well about the traditional arguments about why Interface Inheritance is prefered to multiple inheritance, there has been already a post here :
http://stackoverflow.com/questions/191691/should-c-include-multiple-inheritance
But according to Stroutroup the real reason why Microsoft and Sun decided to get rid off multiple inheritance is that they have vested interest to do so: instead of putting features in the languages, they put in frameworks so that people then become tied to their platform instead of people having the same capability at a language standard level.
What do you think ?
Hello,
I want to upload dynamically content from a soccer live score website to my database.
I also want to do this daily, from a single page on that website (the soccer matches for that day).
If you can help me only with the connection and retrieval of data from that webpage, I will manage the rest.
website: http://soccerstand.com/
language: php/java - mysql
Thank you !
Hello.
I am making my own crude MP3 player, and I now have a JList with which I have populated a number of files in the form of MP3 objects (displayed on frame using DefaultListModel).
I would now like to have the oppurtunity to save this JList to a file on disk. How would I go about doing this?
I'm very new with programming and Java, so help is greatly appreciated.
hello .. im trying to extract frames from a video .. and i picked ffmpeg ( tell me if you know something better ) for this task
i downloaded it's source .. and i don't know how to use it ?? how do i compile it ??
what is the recommended language for it ?? i know python and C++
please note that i use windows vista 64x .
I would like code like this:
(define-struct thing (a b c))
(define th (make-thing 1 2 3))
to print something like this:
(make-thing 1 2 3)
when I type "th" into either the DrScheme or MzScheme repl. I am using the language "pretty big" in DrScheme with output style set to "constructor". This is what I get in DrScheme:
(make-thing ...)
(i literally get the three dots)
In MzScheme:
#<thing>
Hi,
Is there any way to change backlight turn off TIME using programming(Preferred c# or vb.net other c++ can be used too)? I guess, may be it is changed using registry info or API.
Manually, it is done by:
Setting Backlight (Battery Power and External Power)
Thank you
Though it's on the edge of programming questions, I think this is still relevant here, as only those of us actually doing the coding for a site would be considering this.
I've been reading more about keyword placement, and it seems to me like a good place to do keyword placement would be in the class and id names chosen for the elements they are representing. I'm not talking about any kind of black-hat keyword stuffing thing but real legitimate use of descriptive keywords for elements.
Is this something that is actively done for SEO?
I have a UIWebView inside a normal UIViewController. The content of the UIWebView is programming/dynamically created in my program, and it could be very long (multiple table rows). Somehow, after loading, the page won't scroll more then one and half screen of content when swipe on the screen. Because of that I can only see the beginning few rows of data, but not the many others after them. Why is that?
I have programed an application on windows XP and in Visual Studio with c++ language.
In that app I used LoadResource() API to load a resource for giving a file in the resource memory.
It returned a pointer of memory block and I wanna cast the pointer to the std stream to use for compatibility.
Could anyone help me?
I need to teach myself Winforms and user interface programming and want a decent book that will go thoroughly into the ins and outs of how to accomplish things.
Can anyone suggest a good book?
I know C# pretty well and have messed about with Winforms in the designer before.
Thank you
I'm using the standard gcc compiler in math software development with C-language. I don't know that much about compilers or compiler options, and I was just wondering, is it possible to make faster executables using another compiler or choosing better options? The default Makefile sets options -ffast-math and -O3 and I think both of them have some impact in the overall calculation time. My software is using memory quite extensively, so I imagine some options related to memory management might do the trick?
Any ideas?
Hi all,
I've been programming in Java for a few courses in the University and I have the following question:
Is it methodologically accepted that every class should implement an interface? Is it considered bad practice not to do so? Can you describe a situation where it's not a good idea to use interfaces?
Thanks.
I'm on my way to programming a database application and in our course we are told to implement a library of elements using one of the Java Collections. Each of the elements has a unique ID with which it's supposed to be addressed. Now I am wondering how this can be done.
I though about using a ListArray but this won't work because the only way of addressing List elements is through the index which you can't control.
Do you have some advice for me?
REPL's are very useful for live debugging and experimentation. Most dynamic languages such as Ruby, Python, etc come with one built-in, however it is more difficult to build one for a statically-typed language such as C++.
Despite the technical challenges, are there any REPL's available for C++?
When programming, I would like to split one large file(which contains main function) to many small files, so there is one common case: functions in small files can modify the var from main file, so i think extern is very useful!
for instance:
in main.c
extern int i = 100;
in small.c
extern int i;
fprintf(stdout, "var from main file: %d\n", i);
I just want to know is my understanding right?
I am new to C++ programming, but I have experience in Java. I need guidance on how to pass objects to functions in C++.
Do I need to pass pointers, references, or non-pointer and non-reference values? I remember in Java there are no such issues since we pass just the variable that holds reference to the objects.
It would be great if you could also explain where to use each of those options.
Recently I did a Java programming exercise successfully which was sent by a recruiting firm, The problem statement goes like this 'There are two text files FI(records abt files and directory information) and FS(containing blocks of data) which represent a file Index and file System respectively and I was supposed to write a static read method in a class which will read the file from the FS depending upon the path string provided using FI' My question is where can I get these kind of exercises to solve, the complexity should be above average to tough.
I'm reading this article about Comet http://en.wikipedia.org/wiki/Comet_(programming). It mentions that browser should support multipart/x-mixed-replace to make XmlHttpRequest Streaming possible.
Why this multipart/x-mixed-replace is necessary?
Without this header, HTTP response can still be chunked and sent piece by piece to browser, right?
I'm looking for a library that simplify tempo/bpm audio detection.
Something similar to this http://adionsoft.net/bpm/ , but to use on *NIX machines.
Any language, but preference goes to php, perl, python.
