• Wordpress with user login and file manager support

  - by Don

  This may be a RTFM kind of thing, so I'll apologize up front. I've been asked by a friend I used to freelance for if there's a solution in Wordpress where users an login, then they can upload their own files in a "my docs" kind of thing. I've never used WP, so before I dig into their info I thought I'd see if anyone here can confirm or maybe point me to a resource. It's one of those "I'll look up at lunch and get back to you" things, which is why I'm bugging you all before reading the docs. Thanks

• Making retro games: Any good known game architectures?

  - by A.Quiroga

  I'm trying to do a remake of Snowbros . I'm doing it using libgdx but at each time i must try to thought how things got done . For example the physics of the jump and collisions . It seams to be time perfect , but i use the deltaTime to try to aproximate the value in game . I think in this case maybe its using some calcs with processor Hz , but i don't know. Then the simple question , is there any resources of how did they programm this games? Or any idea of the simple ideas repeated each game to game in the old style retro games.

• How do you stop yourself from programming?

  - by dan

  Lately I've started earning enough off my software to not have to do consulting to support myself. So I work full time designing and writing my own software products. The problem is that there are no boundaries between my work and my life any more. When I mostly did consulting, I was weary enough of work at the end of the workday to go home and do other things. But now, I sit down to program in the morning, and before I know it it's 11pm and I'm still writing software and not bored or tired at all. I have to force myself to go to sleep. I feel happy and fulfilled, but objectively, I know I need more balance and variety in my life. Any tips or suggestions on how to pull yourself away from the console?

• Bringing in New Architecture During Maintenance on Legacy Systems

  - by Mike L.

  I have been tasked with adding some new features to a legacy ASP.NET MVC2 project. The codebase is a disaster and I want to write these new features with some thought behind the implementation and not just throw these new features into the mess. I would like to introduce things like dependency injection and the orchestrator pattern; just to the code that I am going to write. I don't have enough time to try to refactor the entire system. Is it OK to not be consistent with the rest of the codebase and add new features following different design principles? Should I not introduce new patterns and just get the features implemented? I feel like it might be confusing to the next person to see parts of the system using a design that other parts are not following.

• Design leaderboard ratings for quiz games

  - by PeterK

  Back in March 2011 i started the following post: How to design a leaderboard? Now my quiz game have been out for approximately a year and sold pretty decently. I am working on to update the game design and is again looking into the leaderboard design to make it better as i am not happy with it. Currently i rate players on number of correct answers, which is not good as it does not consider things like number of games, difficulty levels etc. I also have "extended" stats behind the UITableView (Leaderboard). A player can play based on three levels of difficulty: hard, medium or easy Difficulty levels can be mixed between players in a game Each game can be one to six players, so there can be single games or duels Between 2 and 30 questions per game As i am considering integrating Game Center Leaderboard i need to design a better rating system so i would like to ask for some ideas how to do the rating based on the above. I am thinking about how much a point would be worth and what it includes.

• Services or Shared Libraries?

  - by Royal

  I work in an environment where we have several different web applications, where each of them have different features but still need to do similar things: authentication, read from common data sources, store common data, etc. Is it better to build the shared functionality into a set of services, to be called by the web apps, or is it better to make a shared library, which the webapps include? The services or libraries would need to access various databases, and it seems like keeping that access in a single place (service) is a good idea. It would also reduce the number of database connections needed. A service would also keep the logic in a single place, but then it could be argued that a shared library can do the same thing. Are there other benefits to be gained from using services over shared libraries?

• How do I stop Ubuntu Precise freezing/hanging

  - by artfulrobot

  At least once a day I lose work on my (2 different) Intel i5 machines running Ubuntu 12.04. The entire system will freeze/lock-up/hang, and never return. At this point nothing works; even the caps lock key doesn't toggle the light on the keyboard; Ctrl-Alt-F1 won't do anything either. askubuntu.com is apparently where I'm directed for support. I suspect this is a kernel bug. But I simply can't keep losing work like this, so I'm anxious to try whatever it takes to get the thing reliably working. Can you suggest something I can try to fix the problem an existing bug I can follow progress on and contribute to (from users/tester's POV) the most constructive way I can contribute to helping fix the problem, keeping in mind that I do need the computer (so can't do things that might "brick" it!)

• Liskov substitution principle with abstract parent class

  - by Songo

  Does Liskov substitution principle apply to inheritance hierarchies where the parent is an abstract class the same way if the parent is a concrete class? The Wikipedia page list several conditions that have to be met before a hierarchy is deemed to be correct. However, I have read in a blog post that one way to make things easier to conform to LSP is to use abstract parent instead of a concrete class. How does the choice of the parent type (abstract vs concrete) impacts the LSP? Is it better to have an abstract base class whenever possible?

• 2D vector graphic html5 framework

  - by Yury

  I trying to find html5 game framework by following criteria: 1)Real good performance. 2)Good support of vector graphic( objects which contains canvas elements -line, rec,bezierCurve etc.) 3)Easy port to mobile. Optional- Physics Engine. I found 1)Pixi.js- it looks like real good, but i didn't find any info about "vector objects" support. 2) i found "vector objects" support in paper.js I need something like these: http://paperjs.org/examples/chain/ and http://paperjs.org/examples/path-intersections/. But it looks like paper.js- not so good performance as pixi.js. And it is not game engine. Is there any good framework meets these requirements? P.S. I found similar question here Which free HTML5-based game engine meets these requirements?. But it was a long time ago. A lot of new things were created since 2011.

• How a graphic designer can get into game programming?

  - by Robert Valdez

  I'm a graphic design student hoping to pursue a career as a video game artist. However, I want to do some game development as a hobby. I'd like to develop games for the desktop or mobile phones. The only programming experience I have is that I took an intro to programming with java class in which I learned how to make web applets using java's swing library. It was awful. I think the only things I took from the class was what OOP is and how to work with variables and data types and some methods. I also learned some actionscript myself which was fun unfortunately my flash tutorial expired and it's too expensive to buy;( What I was looking to do is learn one programming language and build a game with it without having to go through so many hoops and with minimum cost. If it's possible. I would love to learn C++, but I read it's not best for a beginning programmer. What programming languages or maybe software kits/platforms would you recommend?

• Why is Lubuntu default desktop environment

  - by John

  So I just wanted to try things out on 14.04, so I did sudo apt-get install lxde sudo apt-get install lubuntu-desktop When I get to the greeter, it reads Lubuntu (Default) Lubuntu Netbook LXDE Openbox Ubuntu Why is Lubuntu default? I don't know if its because its the last thing I installed or if its because it is in alphabetical order. I'm tempted to test this theory by installing Xubuntu and see if it becomes default. I'd like it to read Ubuntu (Default) and have the Ubuntu splash instead. When I open lightdm.conf, there is no line "user-session" nor "greeter-session". They are missing. Is this normal and I have to add it manually?

• Bzr to git migration

  - by Sardathrion

  I am planning to do two things on several large (several gigs) and old (several years) repositories: Move from bzr to git without losing the commit history. Restructure all the repositories either using bzr or git. This will involve moving files/directories from one repository to another with its change history. Doing both at once would be foolish (I think!) but I am not sure which one should be done first. Any suggestions? Anything I should watch out for when migrating/restructuring?

• Desktop sharing options for Ubuntu 12.04 with Unity

  - by Stefan Buynov

  I would like to be able to access my office Ubuntu 12.04 machine from home, from a Mac Mini with Mac OSX. I have a VPN and I am able to access my office machine over SSH, so connectivity is not a problem. I browsed other questions, and it seems that there are several options: VNC XRDP FreeNX (haven't heard this one before) Are there any other? I have been using Remote Desktop on Windows before, and I actually like it. Not sure how well is XRDP implemented. I also used VNC several years back, and I didn't like its performance back then - not sure if things have changed since then. As I said above, the machine I want to access is running Ubuntu 12.04, with Unity. And I am using Unity by choice - I really like it and would like to continue using it :) The client computer is running Mac OSX (Snow Leopard). Based on your previous experience what is the best setup for this environment?

• How can I deal with actor translations and other "noise" in third-party motion capture data?

  - by Charles

  I'm working on a game, and I've run into a problem with motion capture data. My team is using 3DS Max 2011 and trying to put free motion capture files on our models. The problem we're having is it has become extremely hard to find motion capture data that stays in place. We've found some great motion captures of things like walking and jumping but the actors themselves move within the data, so when we attach these animations to our models and bring them into XNA, the models walk forward even when they should technically be standing still (and then there's also the problem of them resetting at the end of the animation). How can we clean up, at runtime or asset-processing time, the animation in these motion capture files?

• Attending the next SQLBits – plan ahead

  - by simonsabin

  We are planning the next SQLBits and it is likely to be the same format as SQLBits V with a training day and a paid Friday. One of the very painful things I have to deal with is odd purchasing processes generally employed by large companies. Use of 3rd parties is the most painful of these, if you can avoid using them it makes our life much easier. We run SQLBits in our spare time and so spending hours dealing with 1 person’s booking is not good. Some people still haven’t paid for SQLBits V and that...(read more)

• What do you do when your naming convention clashes with your language?

  - by Jon Purdy

  Okay, this is one of those little things that always bugged me. I typically don't abbreviate identifiers, and the only time I use a short identifier (e.g., i) is for a tight loop. So it irritates me when I'm working in C++ and I have a variable that needs to be named operator or class and I have to work around it or use an abbreviation, because it ends up sticking out. Caveat: this may happen to me disproportionately often because I work a lot in programming language design, where domain objects may mirror concepts in the host language and inadvertently cause clashes. How would you deal with this? Abbreviate? (op) Misspell? (klass) Something else? (operator_)

• Keep user and user profile in different tables?

  - by Andrey

  I have seen in a couple of projects that developers prefer to keep essential user info in one table (email/login, password hash, screen name) and rest of the non essential user profile in another (creation date, country, etc). By non-essential I mean that this data is needed only occasionally. Obvious benefit is that if you are using ORM querying less fields is obviously good. But then you can have two entities mapped to same table and this will save you from querying stuff you don't need (while being more convenient). Does anybody know any other advantage of keeping these things in two tables?

• Need to set up shared storage for Guest virtual machines that are running on a Xen host

  - by Sajith

  My environment: I am doing these things at home with the purpose of learning about virtualization techniques. My machine have quad core processor that supports Intel-VT and 8GB RAM. XEN is the virtualization platform. In short, all domUs are LVM based. Mainly I have two questions; I need to have shared storage for these VMs. Something like NFS / NAS / iSCSI etc. However, I don't know which one is the best solution. Therefore, can someone tell me which suits best? Please note that, this shared storage need to be accessed by the other physical machines in the network. How to implement the selected solution for question #1? Any tutorials / guidelines / ebooks will be a great help and highly appreciated. Thank you in advance :)

• Should I go back to the same company ?

  - by vinoth

  Hi , I quit the company I was working for(lets call it XYZ) and joined another company . When I quit the company I had very little Software development experience . I thought the rest of the world is a better place . So I complained about the word quality and all that while i quit . One year has taught me a lot of things and I feel XYZ is a much better place (in terms of freedom and decision making in work) . Is it ok to go back ? I am thinking a lot whether to go or not because I quit complaining the nature of work and now I am going back for the same thing . Also I am kind of not very sure to go to other places because , the work and quality are not predictable (I am might become disappointed again ) . Have any of guys been in the same situation before ?

• How to give control over keyboard back to X server after Alt + SysRq + R trick

  - by Øystein Tråsdahl

  Situation: an application freezes the X server and no keyboard input works. So I use Alt+SysRq+R to take the keyboard out of raw mode (make the kernel take control of the keyboard away from the X server). I can then type Ctrl+Alt+F1, kill the bad processes, and everything works again. So far so good. But the keyboard is still in the hands of the kernel, making Alt+Left/Right shortcuts for Decr_Console/Incr_Console. This is annoying, and I want to give control over the keyboard back to the X server. I have tried typing Alt+SysRq+R again, this does not switch things back. I have also tried the command kbd_mode -u, but nothing changes. Any advice?

• Is it a good idea to simplify an character -driven game engine to the point it's unnecessary to learn scripting/programming ?

  - by jokoon

  I remember, and I still think, that one cannot even make a prototyped 3D game to test just simple behaviors without using gigantic tools like unity or knowing extensive C++ programming, design pattern, a decent or basic 3D engine, etc. Now I'm wondering, since I know programming, that I'm still more lucky that the ones who need to learn programming prior to know how to make something: even scripted engines such as unity are not for kids, and to my sense they tend to dictate their ways of doing things, which is not the case with engine like ogre or irrlicht. I remember toying a little with the blender game engine, it was possible to link states or something I don't remember very well. Now I'm thinking that character driven games occupies a big part of the game market. Do you think it is a good idea to make a character-controlled oriented game engine which allows only to build AI instead of anything else ?

• Crappy school, what to do? [closed]

  - by zhenka

  I started programming fairly late. I am 24 years old and about to graduate from a local public university with a really poorly designed curriculum and teachers. Most of the work felt like busy work, and no matter how much I try, it all feels like a waste. I know what a good curriculum looks like. I know what books I should read, but alas it's not so in my university. There is no way at this point that I can catch up to those graduating from places like MIT. My question and this is a serious one: what do I do? Do I just postpone learning the theory I would have learned until later and focus on software engineering skills? How important is the theory in terms of landing a job in New York? Any particular things I should focus on to land a software engineer job? I am very motivated and I just wish someone would give me the time and a chance.

• Java to PHP job change [closed]

  - by Yan

  I've been working with java my entire career(8 years), web servers mostly. And there is a possibility for me to start working in environment that is generally PHP based. I've never worked with PHP before except that I wrote a simple send mail html form once or twice. Is there any benefit in learning a PHP stack or this will be a complete waste of time and degradation as a developer? No offense, but I've heard terrible things about that language and I'm afraid that if people see it in my resume later that would scare them off.

• How do you break down a new project with an existing mega PHP site?

  - by Caveatrob

  I've got to dive into a very large PHP site and have my first client meeting today. All they gave me so far was the URL. How do you guys go about gathering/structuring/documenting and preparing for a new project in a PHP environment? What things do you ask for up front? PS - I know there are other general questions about this but I want a PHP-flavored one, including tools (even if universal) and approaches. Thanks!! I'm excited but also scared.

• Where can I learn image processing? [on hold]

  - by Little Child

  I am learning image processing on my own and I have managed to teach myself a fair few things like: Making images grayscale using 3 different methods Applying a 'pixellate' filter Applying a 'pointillize' filter Make images out of lines Now, I want to take my knowledge further but I do not know how. Adding more information: I am interested in making software like Photoshop or Gimp (although it won't be half as powerful as these 2). So, I want to learn to apply various creative effects to an image. Can someone please suggest resources for this??
