• Are there any guidelines for laying out screen "real estate?"

  - by Corey

  I'm wondering if there is any information about creating a decent page layout so that your website will appeal to users of all resolutions. For example, the optimal width for pages. It seems like on my resolution, most websites have their content centered and covers about 80% of the page, which is easy on the eyes. Or maybe the height of the website's logo/header -- some sites I stumble upon have a huge logo with links or navigation under it, making it so that I need to scroll down to see the actual content, like articles or images (these sites don't keep me for very long). I understand that every user is different and may have browser extensions, page zoom or may be running some ancient system that displays in 640x480. I'm not looking for a "best" solution, but rather, some guidelines about designing to accommodate different resolutions. Basically, how can I make sure that I don't design a page where a paragraph might display in several easy-to-read lines on my resolution, but it turns into a single line on a 1920x1080 resolution and makes it hard for the user to follow?

• managing information/functionality on shared common project classes

  - by ilansch

  In my company, we have a common solution the contains common projects (2 projects so far, one for .net 3.5 and one for .net 4.5). My main problem is that during time, a lot of code is added, for example hosting a process as windows service is a class called ServiceManagement, But no one but the developer knows it, and if someone wants to use this shared class, he does not know it exist. So i am looking for a way to document and manage all the classes with tags, a 3rd party util/web util, that i can search for tags and maybe find common classes that i can use (if we keep all our code well-documented). Does anyone familiar with sort of tools ?

• Convert filenames to their checksum before saving to prevent duplicates. Is is a smart thing to do?

  - by Xananax

  TL;DR:what the title says I am developing some sort of image board in PHP. I was thinking of changing each image's filename to it's checksum prior to saving it. This way, I might be able to prevent duplicates. I know this wouldn't work for two images that are the same but differ in size or level of compression or whatnot, but this method would allow for an early check. What bugs me is that I never saw this method implemented anywhere, so I was wondering if there is a catch to it. Maybe it is just more efficient to keep the original filename and store the hash in DB? Maybe the whole method is just not useful and my question is moot? What do you think? On a side note, I don't really get how hashes are calculated so I was wondering, if my first question checks out, if it would be possible to calculate the likeness that two images are similar by comparing hashes (levenshtein or something of the sort).

• InnoDB Compression Improvements in MySQL 5.6

  - by Inaam Rana

  MySQL 5.6 comes with significant improvements for the compression support inside InnoDB. The enhancements that we'll talk about in this piece are also a good example of community contributions. The work on these was conceived, implemented and contributed by the engineers at Facebook. Before we plunge into the details let us familiarize ourselves with some of the key concepts surrounding InnoDB compression. In InnoDB compressed pages are fixed size. Supported sizes are 1, 2, 4, 8 and 16K. The compressed page size is specified at table creation time. InnoDB uses zlib for compression. InnoDB buffer pool will attempt to cache compressed pages like normal pages. However, whenever a page is actively used by a transaction, we'll always have the uncompressed version of the page as well i.e.: we can have a page in the buffer pool in compressed only form or in a state where we have both the compressed page and uncompressed version but we'll never have a page in uncompressed only form. On-disk we'll always only have the compressed page. When both compressed and uncompressed images are present in the buffer pool they are always kept in sync i.e.: changes are applied to both atomically. Recompression happens when changes are made to the compressed data. In order to minimize recompressions InnoDB maintains a modification log within a compressed page. This is the extra space available in the page after compression and it is used to log modifications to the compressed data thus avoiding recompressions. DELETE (and ROLLBACK of DELETE) and purge can be performed without recompressing the page. This is because the delete-mark bit and the system fields DB_TRX_ID and DB_ROLL_PTR are stored in uncompressed format on the compressed page. A record can be purged by shuffling entries in the compressed page directory. This can also be useful for updates of indexed columns, because UPDATE of a key is mapped to INSERT+DELETE+purge. A compression failure happens when we attempt to recompress a page and it does not fit in the fixed size. In such case, we first try to reorganize the page and attempt to recompress and if that fails as well then we split the page into two and recompress both pages. Now lets talk about the three major improvements that we made in MySQL 5.6.Logging of Compressed Page Images:InnoDB used to log entire compressed data on the page to the redo logs when recompression happens. This was an extra safety measure to guard against the rare case where an attempt is made to do recovery using a different zlib version from the one that was used before the crash. Because recovery is a page level operation in InnoDB we have to be sure that all recompress attempts must succeed without causing a btree page split. However, writing entire compressed data images to the redo log files not only makes the operation heavy duty but can also adversely affect flushing activity. This happens because redo space is used in a circular fashion and when we generate much more than normal redo we fill up the space much more quickly and in order to reuse the redo space we have to flush the corresponding dirty pages from the buffer pool.Starting with MySQL 5.6 a new global configuration parameter innodb_log_compressed_pages. The default value is true which is same as the current behavior. If you are sure that you are not going to attempt to recover from a crash using a different version of zlib then you should set this parameter to false. This is a dynamic parameter.Compression Level:You can now set the compression level that zlib should choose to compress the data. The global parameter is innodb_compression_level - the default value is 6 (the zlib default) and allowed values are 1 to 9. Again the parameter is dynamic i.e.: you can change it on the fly.Dynamic Padding to Reduce Compression Failures:Compression failures are expensive in terms of CPU. We go through the hoops of recompress, failure, reorganize, recompress, failure and finally page split. At the same time, how often we encounter compression failure depends largely on the compressibility of the data. In MySQL 5.6, courtesy of Facebook engineers, we have an adaptive algorithm based on per-index statistics that we gather about compression operations. The idea is that if a certain index/table is experiencing too many compression failures then we should try to pack the 16K uncompressed version of the page less densely i.e.: we let some space in the 16K page go unused in an attempt that the recompression won't end up in a failure. In other words, we dynamically keep adding 'pad' to the 16K page till we get compression failures within an agreeable range. It works the other way as well, that is we'll keep removing the pad if failure rate is fairly low. To tune the padding effort two configuration variables are exposed. innodb_compression_failure_threshold_pct: default 5, range 0 - 100,dynamic, implies the percentage of compress ops to fail before we start using to padding. Value 0 has a special meaning of disabling the padding. innodb_compression_pad_pct_max: default 50, range 0 - 75, dynamic, the  maximum percentage of uncompressed data page that can be reserved as pad.

• Boots up into Terminal

  - by Jacob Larson

  I am running a 64 bit version of Ubuntu 12.04.1, and I when I boot up, I am thrown (Rather violently. :P) a full-sized terminal, instead of my lovely GUI login screen.. So I looked around and tried the "startx" command, which works like a charm. Only problem is that now, I have no clue how to keep it from booting to the terminal every time, and boot up into the regular GUI with all my stuff. I did install some kernel updates the night before, though I restarted my computer twice after I had done so without a problem. Thanks for your time!

• Browser window size statistics?

  - by Litso

  Hey all, I was wondering, are there any statistics available on what size users have their browser set to nowadays? I know the screen resolutions (we have analytics, which shows those as well) but I doubt a lot of people with 1280*xxx and higher still browse full-screen though. My boss is determined to keep our website 900px wide though, because that way people with 1800*xxx resolutions can have two browser windows next to eachother without having to scroll horizontally. I have never seen anyone browse with two adjacent browser windows like that except here at my current job, so I'm kind of doubting whether this is the best decision or just his personal preference. Anyone that can help out here?

• Migration from XNA to SharpDX

  - by Wouter

  My fear is that XNA has reached the end of the road. To keep up with the latest technology a shift to another game framework might be needed. We have many games in a large codebase, all based on XNA. My question is, how much work would it be to migrate to SharpDX and are there other possibilities? Our code base mainly uses basic 3D rendering and the SpriteBatch, no fancy shader stuff. Update: I should have mentioned we only use 2.5D, we have a simple engine that builds textured quads to render text and animated sprites. Also for sound we use XACT (what else..) with some effects.

• Performing user authentication in a CodeIgniter controller constructor?

  - by msanford

  In "The Clean Code Talks -- Unit Testing" (http://youtu.be/wEhu57pih5w), Miško Hevery mentions that "as little work as possible should be done in constructors [to make classes more easily testable]'. It got me thinking about the way I have implemented my user authentication mechanism. Having delved into MVC development through CodeIgniter, I designed my first web application to perform user authentication for protected resources in controllers' constructors in cases where every public function in that controller requires the user to be authenticated. For controllers with public methods having mixed authentication requirements, I would naturally move the authentication from the constructor to each method requiring authentication (though I don't currently have a need for this). I made this choice primarily to keep the controller tight, and to ensure that all resources in the controller are always covered. As for code longevity and maintainability: given the application structure, I can't foresee a situation in which one of the affected controllers would need a public method that didn't require user authentication, but I can see this as a potential drawback in general with this implementation (i.e., requiring future refactoring). Is this a good idea?

• Smooth Camera Rotation around 90 degrees

  - by Nicholas

  I'm developing a third person 3D platformer in XNA. My problem is when I try to rotate the camera around the player. I would like to rotate (and animate) the camera 90 degrees around the player. So the camera should rotate until it has reached 90 degrees from the starting position. I cannot figure out how to keep track of the rotation, and when the rotation has made the full 90 degrees. Currently my cameras update: public void Update(Vector3 playerPosition) { if (rotateCamera) { position = Vector3.Transform(position - playerPosition, Matrix.CreateRotationY(0.1f)) + playerPosition; } this.viewMatrix = Matrix.CreateLookAt(position, playerPosition, Vector3.Up); } The initial position of the camera is set in the constructor. The "rotateCamera" bool is set on keypress. Thanks for the help in advance. Cheers.

• How important is it for a programmer to have an online presence?

  - by Jer

  I've noticed more and more mentions (both in posts here and in actual job descriptions) of programmers's "portfolios" - typically their public profiles on sites such as this, github, etc. How important is this, and would companies (startups in particular) reject (or immediately discard withouth even interviewing) otherwise outstanding candidates who don't have an online presence? Personally, I prefer to keep a very low profile online. My name here cannot identify me, and I have other handles for other sites. I have a very spartan (and completely private) Facebook page. I do code on my own but the code lives in local repositories. In general, the less information online about me, the better. I could see a designer needing some sort of online portfolio, but for a programmer, is this really a big negative when job-searching?

• Methods of Geotargeting and optimising for location

  - by Switchfire

  This is somewhat an SEO question and somewhat a general web developer question. Our company website is pretty awful, I'm currently redesigning the new one, the problem is they have a directory called regions, which contains page for around 200 different locations around the country, all stuffed to the brim with keywords and useless things. Some of these pages work and the traffic's good enough to keep a few of them. Apart from creating a page for everyone again, is there another way of targeting all these locations without having to create a new page for each or is the a more dynamic way to do it? Any ideas or suggestions?

• What tools to use for efficient link building?

  - by Evgeny

  As most SEO experts keep saying, it is not just the content that you have - but also a hefty amount of quality incoming links to your content that is important -- these are the two ways to get to the top of the search results. The question is where do I find the incomnig links? One way I know is Google Blog Search, it can be used to find blogs with related information to your content and some allow to leave comments. The comments usually consist of your name, e-mail and website. If you put your keyword instead of your name, then the keyword turns into a link to your website. Unfortunately most blogs put rel=nofollow on such links, but some blogs don't do that. What other ways are there to find quality pages to put keywords links back to your website? Quality link usually means: located on a page with relevant content does not have a rel=nofollow in the <a has a relevant keyword as in <a href=websitekeyword</a the page with the link has high PageRank (3+) and TrustRank

• Charles Barkley syndrome

  - by dacracot

  Charles Barkley was an excellent basketball player, a hall of fame, and a dream team member. He played for the 76ers, Suns, and Rockets. Yet he never won an NBA championship. Some might argue this was because he was never surrounded by other players of his caliber, and in the NBA, you can't win on your own. So what does this have to do with programming? How many of you out there feel like Sir Charles? Leading your team in every category, KLOCs, bugs fixed, systems configured... Always the one pushing for improvements, upgrading systems, negotiating with customers... Feeling like you are carrying the team. Anger just under the surface. Only to retire eventually, without "the ring"1. 1: Keep in mind, Charles never blamed his team. He just performed at his best.

• Hard-copy approaches to time tracking

  - by STW

  I have a problem: I suck at tracking time-on-task for specific feature/defects/etc while coding them. I tend to jump between tasks a fair bit (partly due to the inherit juggling required by professional software development, partly due to my personal tendancy to focus on the code itself and not the business process around code). My personal preference is for a hard-copy system. Even with gabillions of pixels of real-estate on-screen I find it terribly distracting to keep a tracking window convienient; either I forget about it or it gets in my ways. So, looking for suggestions on time-tracking. My only requirement is a simple system to track start/stop times per task. I've considered going as far as buying a time-clock and giving each ticket a dedicated time-card. When I start working on it, punch-in; when done working, punch-out.

• Feeling a bit... under-challenged in my university course

  - by Corey

  I'm currently a sophomore at my university, majoring in Computer Science. Obviously, there are some programming courses as part of my curriculum. However, I'm feeling very underwhelmed by its progress. I've self-taught myself a lot and like to code in my spare time as a hobby. I'm currently in Computer Science II. I never took CS 1 because it seemed rather basic -- I asked someone in the department if they would override my CS 1 requirement if I passed their final (which I did with flying colors). Anyway, the class is going by quite slowly. It seems like the rest of the class has a hard time understanding some basic concepts, which the professor needs to keep going over to help them understand. Is this normal? Looking at the class schedule, I seem to know everything except for one or two things near the very end of the semester. Is there a different perspective I can look at this through so it doesn't seem so boring?

• What's the best way of marketing to programmers?

  - by Stuart

  Disclaimer up front - I'm definitely not going to include any links in here - this question isn't part of my marketing! I've had a few projects recently where the end product is something that developers will use. In the past I've been on the receiving end of all sorts of marketing - as a developer I've gotten no end of junk - 1000s of pens, tee-shirts and mouse pads; enough CDs to keep my desk tea-free; some very useful USB keys with some logos I no longer recognise; a small forest's worth of leaflets; a bulging spam folder full of ignored emails, etc... So that's my question - What are good ways to market to developers? And as an aside - are developers the wrong people to target? - since we so often don't have a purchasing budget anyways!

• Is switch-case over enumeration bad practice?

  - by Puckl

  I have an enumeration with the commands Play, Stop and Pause for a media player. In two classes I do a switch-case over the received commands. The player runs in a different thread and I deliver the commands in a command queue to the thread. If I generate class diagrams the enumeration has dependencies all over the place. Is there a nicer way to deal with the commands? If I would change/extend the enumeration, I would have to change several classes. (Its not super important to keep the player extensible, but I try to write nice software.)

• Best way to store a large amount of game objects and update the ones onscreen

  - by user3002473

  Good afternoon guys! I'm a young beginner game developer working on my first large scale game project and I've run into a situation where I'm not quite sure what the best solution may be (if there is a lone solution). The question may be vague (if anyone can think of a better title after having read the question, please edit it) or broad but I'm not quite sure what to do and I thought it would help just to discuss the problem with people more educated in the field. Before we get started, here are some of the questions I've looked at for help in the past: Best way to keep track of game objects Elegant way to simulate large amounts of entities within a game world What is the most efficient container to store dynamic game objects in? I've also read articles about different data structures commonly used in games to store game objects such as this one about slot maps, but none of them are really what I'm looking for. Also, if it helps at all I'm using Python 3 to design the game. It has to be Python 3, if I could I would use C++ or Unityscript or something else, but I'm restricted to having to use Python 3. My game will be a form of side scroller shooter game. In said game the player will traverse large rooms with large amounts of enemies and other game objects to update (think some of the larger areas in Cave Story or Iji). The player obviously can't see the entire room all at once, so there is a viewport that follows the player around and renders only a selection of the room and the game objects that it contains. This is not a foreign concept. The part that's getting me confused has to do with how certain game objects are updated. Some of them are to be updated constantly, regardless of whether or not they can be seen. Other objects however are only to be updated when they are onscreen (for example, an enemy would only be updated to react to the player when it is onscreen or when it is in a certain range of the screen). Another problem is that game objects have to be easily referable by other game objects; something that happens in the player's update() method may affect another object in the world. Collision detection in games is always a serious problem. I need a way of containing the game objects such that it minimizes the number of cases when testing for collisions against one another. The final problem is that of creating and destroying game objects. I think this problem is pretty self explanatory. To store the game objects then I've considered a number of different methods. The original method I had was to simply store all the objects in a hash table by an id. This method was simple, and decently fast as it allows all the objects to be looked up in O(1) complexity, and also allows them to be deleted fairly easily. Hash collisions would not be a major problem; I wasn't originally planning on using computer generated ids to store the game objects I was going to rely on them all using ids given to them by the game designer (such names would be strings like 'Player' or 'EnemyWeapon4'), and even if I did use computer generated ids, if I used a decent hashing algorithm then the chances of collisions would be around 1 in 4 billion. The problem with using a hash table however is that it is inefficient in checking to see what objects are in range of the viewport. Considering the fact that certain game objects move (as well as the viewport itself), the only solution I could think of in order to only update objects that are in the viewport would be to iterate through every object in the hash table and check if it is in the viewport or not, updating only the ones that are in the valid area. This would be incredibly slow in scenarios where the amount of game objects exceeds 500, or even 200. The second solution was to store everything in a 2-d list. The world is partitioned up into cells (a tilemap essentially), where each cell or tile is the same size and is square. Each cell would contain a list of the game objects that are currently occupying it (each game object would be inserted into a cell depending on the center of the object's collision mask). A 2-d list would allow me to take the top-left and bottom-right corners of the viewport and easily grab a rectangular area of the grid containing only the cells containing entities that are in valid range to be updated. This method also solves the problem of collision detection; when I take an entity I can find the cell that it is currently in, then check only against entities in it's cell and the 8 cells around it. One problem with this system however is that it prohibits easy lookup of game objects. One solution I had would be to simultaneously keep a hash table that would contain all the positions of the objects in the 2-d list indexed by the id of said object. The major problem with a 2-d list is that it would need to be rebuilt every single game frame (along with the hash table of object positions), which may be a serious detriment to game speed. Both systems have ups and downs and seem to solve some of each other's problems, however using them both together doesn't seem like the best solution either. If anyone has any thoughts, ideas, suggestions, comments, opinions or solutions on new data structures or better implementations of the existing data structures I have in mind, please post, any and all criticism and help is welcome. Thanks in advance! EDIT: Please don't close the question because it has a bad title, I'm just bad with names!

• PowerShell, Start-Job, -ScriptBlock = sad panda face
