• Learn a NoSQL or become a badass with traditional RDMS - Where is/will the work be?

  - by beck

  I'm half way through my MSc and am thinking about my dissertation which I get 3 months to work on full time. Im very comfortable with the traditional Relational Database, the question is should I work on a project where I get a good understanding of something like Cassandra, or should I really push my RDMS knowledge to the limit. Getting great at something like MySQL is a solid safe option, will there really be much work for me with Cassandra in my tool belt? I would love to do either.... Thanks for your opinions and advice.

• Cleaning a dataset of song data - what sort of problem is this?

  - by Rob Lourens

  I have a set of data about songs. Each entry is a line of text which includes the artist name, song title, and some extra text. Some entries are only "extra text". My goal is to resolve as many of these as possible to songs on Spotify using their web API. My strategy so far has been to search for the entry via the API - if there are no results, apply a transformation such as "remove all text between ( )" and search again. I have a list of heuristics and I've had reasonable success with this but as the code gets more and more convoluted I keep thinking there must be a more generic and consistent way. I don't know where to look - any suggestions for what to try, topics to study, buzzwords to google?

• Bad anti-aliasing in some applications

  - by Matty

  There was an update a few weeks ago that seemed to mess with anti-aliasing in some applications. Firefox, Thunderbird, and the text in some apps such as Mousepad and Leafpad (but not the rest of the window) are affected, whereas Chrome and everything else seems to be just fine. Attached are two screenshots showing the difference between rendering in Firefox and Chrome. The anti-aliasing settings are the same as they've always been, which have worked just fine - full hinting, RGB sub-pixel order. I'm really not sure what's going on and am thinking that it might be faster to fix this problem by re-installing, but is there anything I can try first as re-installing is the last thing I want to do? I'm running Xubuntu 12.04.

• Are RSS feeds used? [closed]

  - by acidzombie24

  I was thinking about implementing RSS feeds on my site. The one thing that came to mind is Are RSS feeds ever used?! I don't use them nor know anyone who does. I know to use them it must be through an rss feed program or built in with the browser. I like my browser clean and i know many ppl dont know how to use/configure their browser. So with my thoughts i deducted that rss are not used 99.9999% of people (thats 4 decimal places which is really saying something). Now twitter on the other hand or even email may be used. But I have doubts about rss feeds. Can anyone give me statistics or change my mind on implementing it? I suspect it would be simple but i dont think i should bother if no one will ever use it. I dont even use SE/SO RSS feeds.

• Best practice for bulk eCommerce product upload?

  - by Or W

  I'm thinking about opening a large online store for Jewelry, the one thing that really bothers me is managing the actual operation of taking pictures, uploading and describing all the products. I'm trying to figure out the best way to do it, in terms of performance or the least time consuming. Just a few things to keep in mind I'll have over 1,000 items in the online store I'll have 3-4 pictures for each item, I'm using a DSLR camera if it makes any difference. I'm going to probably use Magento, unless you have better experience with another eCommerce platform that will help me get this done quickly. I'll need to randomly(?) create a product code for each item.

• Efficient way to calculate "vision cones" on 2D tile map?

  - by OverMachoGrande

  I'm trying to calculate which tiles a particular unit can "see" if facing a certain direction on a tile map (within a certain range and angle of facing). The easiest way would be to draw a certain number of tiles outward and raycast to each tile. However, I'm hoping for something slightly more efficient. A picture says a thousand words: The red dot is the unit (who's facing upwards). My goal is to calculate the yellow tiles. The green blocks are walls (walls are between tiles, and it's easy to check if you can pass between two tiles). The blue line represents something like the "raycasting" method I was talking about, but I'd rather not have to do this. EDIT: Units can only be facing north/south/east/west (0, 90, 180, or 270 degrees) and FoV is always 90 degrees. Should simplify some calculations. I'm thinking there's some sort of recursive-ish/stack-based/queue-based algorithm, but I can't quite figure it out. Thanks!

• How would you want to see software intellectual property protected?

  - by glenatron

  Reading answers to this question - and many other discussions of software patents - it seems that most of us as programmers feel that software patents are a bad idea. At the same time we are in the group most likely to lose out if our work is copied or stolen. So what level of Intellectual Property Protection does code and software need? Is copyright sufficient? Are patents necessary? As software is neither a physical object nor simple text, should we be thinking of a third path that falls somewhere between the two? Do we need any protection at all? If you had the facility to set up the law for this, what would you choose?

• Self-documenting code vs Javadocs?

  - by Andiaz

  Recently I've been working on refactoring parts of the code base I'm currently dealing with - not only to understand it better myself, but also to make it easier for others who are working on the code. I tend to lean on the side of thinking that self-documenting code is nice. I just think it's cleaner and if the code speaks for itself, well... That's great. On the other hand we have documentation such as javadocs. I like this as well, but there's a certain risk that comments here gets outdated (as well as comments in general of course). However, if they are up-to-date they can be extremely useful of say, understanding a complex algorithm. What are the best practices for this? Where do you draw the line between self-documenting code and javadocs?

I have the following websites in my mind SitePoint Forums DigitaPoint Forums Adobe Forums Apple Forums Now, as my website is from Apple Niche so would it be better to prefer Apple Forums over other forums?

• Constructive ways to answer "What was your most challenging project? and why?"

  - by tau

  I am asked this question many times in the interviews. What was your most challenging project -- and why? I get confused about which project to tell them and why some project would look challenging or non-challenging. What are they looking for in the answer? Any software is a challenge before it gets started and it becomes a normal software engineering task after it has finished. All softwares I made were challenging until they got finished. Do I misunderstood the word "challenge"? What's wrong in my thinking? What's an appropriate and constructive way to approach this question?

• Creating my own kill cam

  - by DalexL

  I plan on creating my own kill cam system for a sandbox tool set. After thinking about the mechanics of the kill cam itself, however, I'm quite lost. I'm trying to recreate the ones commonly seen in call of duty games that show, from the view of the killer, the actual killing scene. My Thoughts: -I can't just keep in memory when people kill others because I wouldn't know when to start the 'recording process'. There is on way for me to accurately determine when somebody is 'about' to kill someone. -My only real idea so far is to have a complete duplicate of everything loaded off to the side copying all the movement from the original world but with a 10 second delay. That way, all the kill cams would be 10 seconds long and the persons camera would just be moved to the second world of their killer. My Questions: Is there already an accepted way to do this? Does anybody have any good ideas for something like this? Thanks if you can!

• Dependency Injection: Only for single-instance objects?

  - by HappyDeveloper

  What if I want to also decouple my application, from classes like Product or User? (which usually have more than one instance) Take a look at this example: class Controller { public function someAction() { $product_1 = new Product(); $product_2 = new Product(); // do something with the products } } Is it right to say that Controller now depends on Product? I was thinking that we could decouple them too (as we would with single-instance objects like Database) In this example, however ugly, they are decoupled: class Controller { public function someAction(ProductInterface $new_product) { $product_1 = clone $new_product; $product_2 = clone $new_product; // do something with the products } } Has anyone done something like this before? Is it excessive?

• What time planning tools do you use?

  - by sbrattla

  I'm trying to get a better overview of my tasks, and I'm looking for a tool which would let me enter tasks (everything from 2 hour tasks to 2 week tasks) and then simply let me organize these tasks on a timeline. I'm thinking that all tasks would have an estimated duration, and I could then prioritize these tasks by moving them along the timeline to prioritize them. The timeline would then show me the "tasks stack" and how far into the future i'm occupied. I'm not looking for an issue/bug handling system, but simply a tool which lets me get an overview of my tasks. I guess we're more into the category of resource planning. What tools do you use for this?

• Licensing Theme Music from other games

  - by HS01

  As part of my game, I thought it would be fun to make a hidden level that pays tribute to Mario Bros (one of the earliest games I ever played). It would be themed in that way with 8-bit graphics and question mark blocks and completing the level would say "Thank you but the princess is in another castle" or such. For the sound track, I'm thinking of just overlaying the standard mario theme music by playing it on a virtual keyboard using a different instrument/timing or something. My question is, am I legally safe? I'm not using anyone else's actual music, I'm just playing the same tune in a different way myself. Do I have to get licensing for this?

• Make a flowchart to demonstrate closure behavior

  - by thomas

  I saw below test question the other day in which the author's used a flow chart to represent the logic of loops. And I got to thinking it would be interesting to do this with some more complex logic. For example, the closure in this IIFE sort of boggles me. while (i <= qty_of_gets) { // needs an IIFE (function(i) promise = promise.then(function(){ return $.get("queries/html/" + product_id + i + ".php"); }); }(i++)); } I wonder if seeing a flowchart representation of what happens in it could be more elucidating. Could such a thing be done? Would it be helpful? Or just messy? I haven't the foggiest clue where to start, but thought maybe someone would like to take a stab. Probably all the ajax could go and it could just be a simple return within the IIFE.

• How to detect whether an Object came to sleep at a specific position?

  - by Nils Riedemann

  I'm currently writing a small game with box2dweb and I need some direction for this: I'm throwing a Box and have to hit a specific place and trigger an event when the object that's been thrown isn't moving anymore, "fell asleep" so to say. What's the proper way / best practice for this? I'm currently thinking of asking the b2World whether an Object is within a specific AABB and then wait a few seconds, check if it's still there and then trigger the event. But this seems to me like the roundabout way and the object might still be moving inside of that AABB and eventually even drop out of the AABB.

• 4 Ways Your Brand Can Jump From the Edge of Space

  - by Mike Stiles

  Can your brand’s social media content captivate the world and make it hold its collective breath? Can you put something on the screen that’s so compelling that your audience can’t look away? Will they want to make sure their friends see it so they can talk about it? If not, you’re probably not with Red Bull. I was impressed with Red Bull’s approach to social content even before Felix Baumgartner’s stunning skydive from the edge of space. And then they did this. According to Visible Measures, videos of the jump scored 50 million views in 4 days. 1,700 clips were generated from both official and organic sources. The live stream was the most watched YouTube Stream of all time (8 million concurrent viewers). The 2nd most watched live stream was…Felix’ first attempt Oct. 9. Are you ready to compete with that? I ask that question because some brands are still out there tying themselves up in knots about whether or not they should tweet. The public’s time and attention are scarce commodities, commodities they value greatly. The competition amongst brands for that time and attention is intense and going up like Felix’s capsule. If you still view your press releases as “content,” you won’t even be counted as being among the competition. Here are 5 lessons learned from Red Bull’s big leap: 1. They have a total understanding of their target market and audience. Not only do they have an understanding of it, they do something about it. They act on it. They fill the majority of their thoughts with what the audience wants. They hunger for wild applause from that audience. They want to do things that embrace the audience’s lifestyle and immerse in it so the target will identify the brand as “one of them.” Takeaway: BE your target market. 2. They deliver content that strikes the audience right where they emotionally live. If you want your content to have impact, you have to make your audience’s heart race, or make them tear up, or make them laugh. Label them “data points” all you want, but humans are emotional creatures. No message connects that’s not carried in on an emotion. Takeaway: You’re on the inside. If your content doesn’t make you say “wow,” it’s unlikely it will register with fans. 3. They put aside old school marketing and don’t let their content be degraded into a commercial. Their execs seem to understand the value in keeping a lid on the hard sell. So many brands just can’t bring themselves to disconnect advertising and social content. The result is, otherwise decent content gets contaminated with a desperation the viewer can smell a mile away. Think the Baumgartner skydive didn’t do Red Bull any good since he wasn’t drinking one on the way down while singing a jingle? Analysis company Taykey discovered that at the peak of the skydive buzz, about 1% of all online conversation was about the jump. Mentions of Red Bull constituted 1/3 of 1% of all Internet activity. Views of other Red Bull videos also shot up. Takeaway: Chill out with the ads. Your brand will get full credit for entertaining/informing fans in a relevant way, provided you do it. 4. They don’t hesitate to ask, “What can we do next”? Most corporate cultures are a virtual training facility for “we can’t do that.” Few are encouraged to innovate or think big, if think at all. Thinking big involves faith, and work. It means freedom and letting employees run a little wild with their ideas. There will always be the opportunity to let fear of everything that moves creep in and kill grand visions dead in their tracks. Experimenting must be allowed. Failure must be allowed. Red Bull didn’t think big. They thought mega. They tried to outdo themselves. Felix could have gone ahead and jumped halfway up, thinking, “This is still relatively high up. Good enough.” But that wouldn’t have left us breathless. Takeaway: Go for it. Jump. In putting up social properties and gathering fans of your brand, you’ve basically invited people to a party. A good host doesn’t just set out warm beer and stale chips because that’s inexpensive and easy. Be on the lookout for ways to make your guests walk away saying, “That was epic.”

• Windows Server, SQL Server [on hold]

  - by user136329

  I will give high level details of my requirement. We have one web application which accesses the database through SYBASE. The following technologies being used. Visual Studio 2010 .NET frame work 4.5 and for reporting Crystal Report. These are housed on windows server 2008. And for Database we use different servers. We are thinking of moving to SQL Server to be able to utilize the reporting features. My question is does SQL Server can be part of Windows Server 2008 R2 or we needed to have additional server for SQL?

• Input to program without command-line arguments

  - by Core Xii

  Let's assume that there are no command-line arguments. How do you pass input data to a program? I'm thinking you'd write the input to a file with a specific name, such that the program knows to open and read it as input. However, how would one discover the name of that file? Usually, running a command-line program without arguments or with some standard help argument (e.g. \?) produces some instruction on how to use it. But given an environment with no command-line arguments, how does one discover how to operate a program?

• Is there a class or id that will cause an ad to be blocked by most major adblockers?

  Is there a general class or ID for a html element that a high majority of popular adblockers will block on a website it has no information for. My intention is to have my advertisement blocked, avoiding automatic blocking is easy enough... I was thinking of maybe lending some ids or classes from big advertisment companies that area already being fought off quite actively. right now my html <ul id=partners> <li class=advertisment><a href=# class=sponsor><img class=banner></a></li> </ul> Will this work or is there a more solid approach?

• initial Class design: access modifiers and no-arg constructors

  - by yas

  Context: Student working through Class design in personal/side project for Summer. I've never written anything implemented by others or had to maintain code. Trying to maximize encapsulation and imagining what would make code easy to maintain. Concept: Tight/Loose Class design where Tight and Loose refer to access modifiers and constructors. Tight: initially, everything, including setters, is private and a no-arg constructor is not provided (only a full constructor). Loose: not Tight Exceptions: the obvious like toString Reasoning: If code, at the very beginning, is tight, then it should be guaranteed that changes, with respect to access/creation, should never damage existing implementations. The loosening of code happens incrementally and must be thought through, justified, and safe (validated). Benefit: Existing implementing code should not break if changes are made later. Cost: Takes more time to create. Since this is my own thinking, I hope to get feedback as to whether I should push to work this way. Good idea or bad idea?

• Make Interactive Story more Variable [on hold]

  - by Guest0343

  I'm creating an interactive story that allows users to make choices based on a story. However, it doesn't give users room to do much creatively on their own. They are bound by the script at the moment. I'm wondering if anyone can suggest any element I can add that might give users some personalization. I was thinking about maybe character editing, but that doesn't add too much. I also thought about a stats system where they can have certain attributes and stats they might earn, but I'm not sure how they might use those stats. Anything is helpful!
