• Examples of "Lost art" on software technology/development

  - by mamcx

  With the advent of a new technology, some old ideas - despite been good - are forgotten in the process. I read a lot how some "new" thing was already present in Lisp like 60 years ago, but only recently resurface with other name or on top of another language. Now look like the new old thing is build functional, non-mutable, non-locking-thread stuff... and that make me wonder what have been "lost" in the art of development of software? What ideas are almost forgotten, waiting for resurface? One of my, I remember when I code in foxpro. The idea of have a full stack to develop database apps without impedance mismatch is something I truly miss. In the current languages, I never find another environment that match how easy was develop in fox back them. What else is missing?

• How to Name Groups of Apps on the Windows 8 Metro Start Screen

  - by Taylor Gibb

  The Windows 8 Start Screen certainly takes some getting use to, however, one of the things that I really miss about the Start Menu was how i was able to categorize my installed applications. While you cant create folders on the Start Screen, you can group your applications. To get started head over to the Metro Start Screen and move your mouse to the bottom right-hand corner, clicking on the small icon. Now right click on the group of apps that you want to name.

• Projectiles in tile mapped turn-based tactics game?

  - by Petteri Hietavirta

  I am planning to make a Laser Squad clone and I think I have most of the aspects covered. But the major headache is the projectiles shot/thrown. The easy way would be to figure out the probability of hit and just mark miss/hit. But I want to be able to have the projectile to hit something eventually (collateral damage!). Currently everything is flat 2D tile map and there would be full (wall, door) and half height (desk, chair, window) obstacles. My idea is to draw an imaginary line from the shooter to the target and add some horizontal&vertical error based on the player skills. Then I would trace the modified path until it hits something. This is basically what the original Laser Squad seems to do. Can you recommend any algorithms or other approaches for this?

• Target tracking with a small delay (actionscript 3.0)

  - by John Dodson

  I'm having trouble thinking of a good method to track my character with an enemy attack. Of course, I don't want the attack to track my character's current position; I want it to track where the character was about 1 second before (so you can move around and make the attack miss and loop around you sort of a thing). The general structure of my game uses a timer to update all of my events. I have a timer going off every 25 milliseconds that updates everything, including my player's position and the enemies position. Right now I just have the enemy attack directly targeting my character....which works fine except that it's impossible to escape =p. Let me know if I didn't supply enough details. My approach was going to basically be get my character's position from about 1 second ago, then have the enemy target that position, the only problem is I can't think of a good way to get my character's position from previous times. Thanks for the help!

• Lenovo Y460 heats up with Ubuntu 11.10

  - by user54480

  I'm new with Ubuntu and I'm enjoying my experience with Ubuntu 11.10 on my Lenovo ideapad Y460. I'm dual booting Ubuntu with Windows 7 64 bit. It's great using Ubuntu, however I noticed that my laptop heats up rather quickly when I use Ubuntu. Does this have to do with drivers? I have Nvidia GT 425M graphics, but I don't know if this information is relevant. My fans are just not working right as they do in Windows 7. Did I miss installing something or what am I doing wrong?

• What is the advantage to hosting static resources on a separate domain?

  - by Michael Ekstrand

  I notice a lot of sites host their resources on a separate domain from the main site, e.g. StackExchange using sstatic.net, Barnes & Noble using imagesbn.com, etc. I understand that there are benefits to putting your static resources on a separate host, possibly with an efficient static-file web server like nginx, freeing up the main server to focus on serving dynamic content. Similarly, outsourcing to a shared CDN like cloudfront Akamai is logical. What is the benefit to using a separate domain otherwise, though? Why sstatic.net instead of static.stackexchange.com? Update: Several answers miss the core question. I understand that there is benefit to splitting between multiple hosts — parallel downloads, slimmer web server, etc. But what is more elusive is why multiple domains. Why sstatic.net rather than static.stackexchange.com as the host for shared resources? So far, only one answer has addressed that.

• TechEd North America 2012–Day 2 #msTechEd #teched

  - by Marco Russo (SQLBI)

  This is the second day at TechEd North America 2012 and yesterday I had many conversations about PowerPivot and SSAS Tabular. In the evening the book signing at O’Reilley booth has been a big success! I’m writing this post from the speaker’s room. It’s not crowded this morning because the keynote is going on and there are no people also in the hall, everyone is in the keynote room. Today will be a very busy day: I’ll be staffing at Technical Learning Center from 12:30pm to 3:30pm so this is a first chance for joining the conversation about Tabular and DAX. But there is another choice this evening at Community Night starting at 6:30pm until 9:00pm. Join us at this Ask the Expert event! And, well, don’t miss the Many-to-Many Relationships in BISM Tabular from Alberto this afternoon at 5:00 pm in room S330E. Look at my yesterday’s post if you want to look at our full schedule for the week. Enjoy TechEd!

• How to stop getting too focused on a train of thought when programming?

  - by LDM91

  I often find myself getting too focused on a train of thought when programming, which results in me having what I guess could be described as "tunnel vision". As a result of this I miss important details/clues, which means I waste a fair amount of time before finally deciding the path I'm taking to solve the task is wrong. Afterwards, I take a step back which almost always results in me discovering what I've missed in a lot less time.. It's becoming really frustrating as it feels like I'm wasting a lot of time and effort, so I was wondering if anyone else had experienced similar issues, and had some suggestions to stop going down dead ends and programming "blindly" as it were!

• What is So Unique About Node.js?

  - by Adrian Shum

  Recently there has been a lot of praise for Node.js. I am not a developer that has had much exposure to network application. From my bare understanding of Nodes.js, its strength is: we have only one thread handling multiple connections, providing an event-based architecture. However, for example in Java, I can create only one thread using NIO/AIO (which is non-blocking APIs from my bare understanding), and handle multiple connections using that thread, and I provide an event-based architecture to implement the data handling logic (shouldn't be that difficult by providing some callback etc) ? Given JVM being a even more mature VM than V8 (I expect it to run faster too), and event-based handling architecture seems to be something not difficult to create, I am not sure why Node.js is attracting so much attention. Did I miss some important points?

• Is SVN out of style?

  - by jitbit

  It's been only several years since I migrated from Visual Source Safe to SVN. And SVN for me is still kinda "WOW! I can do so many things! SVN is so cool!" But many people around me keep saying "SVN? Really? Meh..." And there's so many of them that I'm worried. Should I move my team to Git / Mercurial or some other fancy thing? I know I sound ridiculous and the obvious answer would be "stay with what works for YOU". SVN does work for me... But every time I create a new project in my repository I keep asking myself - may be this was the time to move? So... Is SVN really that bad? Do I miss a huge opportunity by sticking with it?

• QuadTree: store only points, or regions?

  - by alekop

  I am developing a quadtree to keep track of moving objects for collision detection. Each object has a bounding shape, let's say they are all circles. (It's a 2D top-down game) I am unsure whether to store only the position of each object, or the whole bounding shape. If working with points, insertion and subdivision is easy, because objects will never span multiple nodes. On the other hand, a proximity query for an object may miss collisions, because it won't take the objects' dimensions into account. How to calculate the query region when you only have points? If working with regions, how to handle an object that spans multiple nodes? Should it be inserted in the nearest parent node that completely contains it, even if this exceeds the node's capacity? Thanks.

• OpenGL ES, orthopgraphics projection and viewport

  - by DarkDeny

  I want to make some simple 2D game on iOS to familiarize myself with OpenGL ES. I started with Ray Wenderlich tutorial (How To Create A Simple 2D iPhone Game with OpenGL ES 2.0 and GLKit). That tutorial is quite good, but I miss some parts of a puzzle. Ray creates orthographic projection using some magic numbers like 480 and 320. It is not clear to me why did he take these numbers, and as far as I can see - sprite is not mapped to the ipad simulator screen one-to-one pixel. I tried to play with parameters with which ortho matrix is created, but I cannot figure out what math is here. How can I calculate numbers (bottom, top, left, right, close, far) which will be parameters to orthographic projection matrix creation and have sprite on the screen shown in its original size?
