• Visitor-pattern vs inheritance for rendering

  - by akaltar

  I have a game engine that currently uses inheritance to provide a generic interface to do rendering: class renderable { public: void render(); }; Each class calls the gl_* functions itself, this makes the code hard to optimize and hard to implement something like setting the quality of rendering: class sphere : public renderable { public: void render() { glDrawElements(...); } }; I was thinking about implementing a system where I would create a Renderer class that would render my objects: class sphere { void render( renderer* r ) { r->renderme( *this ); } }; class renderer { renderme( sphere& sphere ) { // magically get render resources here // magically render a sphere here } }; My main problem is where should I store the VBOs and where should I Create them when using this method? Should I even use this approach or stick to the current one, perhaps something else? PS: I already asked this question on SO but got no proper answers.

• creative & complex vs simple and readable

  - by Shirish11

  Which is a better option? Its not always that when you have something creative your code is going to look ugly. But at times it does go a bit ugly. e.g. if ( (object1(0)==object2(0) && (object1(1)==object2(1) && (object1(2)==object2(2) && (object1(3)==object2(3)){ retval = true; else retval = false; is simple and readable bool retValue = (object1(0)==object2(0)) && (object1(1)==object2(1)) && (object1(2)==object2(2)) && (object1(3)==object2(3)); but having something like this will make some newbies scratch their heads. So what do I go for? including simple code everywhere might sometime hamper my performance. what I could think of was commenting wherever necessary but at times u get too curious to know what is actually happening. Any suggestions are welcome.

• Documentation vs tutorials vs video tutorials - which one's better?

  - by Cat

  As a developer/software engineer, what would you say are the most helpful resources when attempting to learn and use a new system? If you had to integrate a new SDK into your codebase/application, which one of the following options would you much rather go with? documentation tutorials video tutorials Same question for learning a new framework (e.g. writing an iOS app, learning Python, integrating the Android SDK, etc.). I'm not referring to becoming an expert, just get to know enough to use a system/language/framework properly. This is a pretty general question, but I think it's very relevant to anyone who's doing engineering work, since learning how to use new systems quickly is a very important skill to have. Thank you!

• 'Unable to mount Filesystem' Error

  - by Charles

  Trying to extract data from a 'bricked' Western Digital MyBook Live 2tb drive. I came across a forum that advised to use Ubuntu (booted from a CD) on my Macbook. Managed to download and create a boot CD for Ubuntu (like this little operating system btw). Booted the machine with the CD and plugged the drive (which I had extracted from it's casing and placed into a external USB SATA case & plugged to the laptop). The drive is seen by Ubuntu but each time I click on the drive, it gives me the following error: Unable to mount 2.0 TB Filesystem Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb4, missing codepage or helper program, or other error In some cases useful info is found in syslog -try dmesg | tail or so I am new to this and spent quite some time searching this site to see if I could find a solution to this problem without troubling anyone. I came up with a few that came close but some of the questioners mentioned that they had lost data...which scared me from going further. I need to basically extract 1 particular folder from the drive. If I can get to mount this volume 'sdb4', there is a folder called 'My_Work' which I need to back up. The rest I have/had a copy of. When I typed in dmesg | tail...I got several lines..but I think ones that are relevant are: [ 406.864677] EXT4-fs (sdb4): bad block size 65536 [ 429.098776] hfs: write access to a journaled filesystem is not supported, use the force option at your own risk, mounting read-only [ 439.786365] hfs: write access to a journaled filesystem is not supported, use the force option at your own risk, mounting read-only [ 445.982692] EXT4-fs (sdb4): bad block size 65536 [ 1565.841690] EXT4-fs (sdb4): bad block size 65536 I read somewhere to try/check 'sudo fdisk -l /dev/sdb4'. It gave me the following result: Disk /dev/sdb44: 1995.8 GB, 1995774623744 bytes 255 heads, 63 sectors/track, 242639 cylinders, total 3897997312 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/sdb4 doesn't contain a valid partition table This is where I reached and got frustrated and decided to try & get help on this without digging myself deeper into a hole! I understand that the answer may already be out there. If so, could someone please point me in the right direction. And if not, could someone please resolve (if possible) my situation!

• Unity gizmos vs. referenced game objects

  - by DuckMaestro

  I'm designing a Unity script that I intend to be highly reusable and as easy as possible to setup within the editor. To this end, a number of properties of this script really need some kind of visual representation on screen. It is an unresolved question to me whether the design of the script should require references to placeholder game objects, OR just Vector3's and float's that have associated gizmos drawn for them. Normally a gizmo would be a natural choice, except that Unity gizmos are not directly manipulable (as far as I can tell). Because of this shortcoming I'm having to consider whether depending on references to placeholder game objects is a more designer-friendly approach ultimately, in spite of the extra setup required, and that it might be counter-intuitive when the placeholder game objects disappear at run-time (which my script would do). Is there a community standard or preference here in this case? Can a Unity-experienced game programmer / designer speak to which approach they feel is more intuitive or more convenient to setup, when using a 3rd party script? Or is this just splitting hairs as long as I ship an example prefab with my script?

• Time development vs production values

  - by Pier

  I have to choose between a framework I already know (Adobe Air), and a framework I know nothing about but is more powerful (Unity). I can do the mobile game I have in mind with both platforms, but the quality of the graphics and development time would be quite different. From an indie mobile perspective, are more detailed graphics justifiable commercially? Is there any objective study that throws some solid conclusions about that?

• nginx errors: upstream timed out (110: Connection timed out)

  - by Sparsh Gupta

  Hi, I have a nginx server with 5 backend servers. We serve around 400-500 requests/second. I have started getting a large number of Upstream Timed out errors (110: Connection timed out) Error string in error.log looks like 2011/01/10 21:59:46 [error] 1153#0: *1699246778 upstream timed out (110: Connection timed out) while reading response header from upstream, client: {IP}, server: {domain}, request: "GET {URL} HTTP/1.1", upstream: "http://{backend_server}:80/{url}", host: "{domain}", referrer: "{referrer}" Any suggestions how to debug such errors. I am unable to find a munin plugin to keep a check on number of upstream errors. Sometime the number of errors per day is way too high and somedays its a more decent 3 digit number. A munin graph would probably help us finding out any pattern or correlation with anything else How can we make the number of such error as ZERO

• Error installing gPodder

  - by Ron Webb

  A few weeks ago (newbie alert!) I started using XUbuntu 12.04 with Xfce 4.8. I'm trying to install gPodder Podcast Client (see https://launchpad.net/~thp/+archive/gpodder). I've added the PPA via terminal commands as instructed. When I click the Install button in the Ubuntu Software Centre I get the following error: Package dependencies cannot be resolved This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time. Details: The following packages have unmet dependencies: gpodder: Depends: python-webkit but it is not going to be installed What do I need to do? Just to make thing more complicated -- I'm not sure, but before I found the launchpad.net link, I think I may have tried to install gPodder from the default Ubuntu repositories (also unsuccessfully). There may be remnants of the previous attempt still installed, which may be blocking the new install. Where/how can I find them?

• Entity and pattern validation vs DB constraint

  - by Joerg

  When it comes to performance: What is the better way to validate the user input? If you think about a phone number and you only want numbers in the database, but it could begin with a 0, so you will use varchar: Is it better to check it via the entity model like this: @Size(min = 10, max = 12) @Digits(fraction = 0, integer = 12) @Column(name = "phone_number") private String phoneNumber; Or is it better to use on the database side a CHECK (and no checking in the entity model) for the same feature?

• Facebook connect vs. OpenID

  - by digit1001

  I just started working on a new project that has a general login feature. One suggestion in a meeting was to look into Facebook Connect or OpenID as an alternative. I'm curious if there's one that has less of a learning curve, or if they can both be used on the same site. Also, when you use either, do you have them initially create the account and just get a verify True/False back that you then use to set up a local user account? I what about forgotten passwords? I'm kind of curious as to best practices for integrated this type of login with a "traditional" one where you store the user info yourself. Thanks, D

• How to fix additional STA driver installation error on 12.04

  - by nibl

  I have a Broadcom BCM4313 wireless driver. It worked fine under 11.04 and the upgrade to 11.10 also went smoothly. The 12.04 upgrade has broken the wireless connection. I've seen several posts about this and all presume you can activate the STA drivers, but that's where it fails on this machine. The log is in /var/log/jockey.log: WARNING: modinfo for module wl failed: ERROR: modinfo: could not find module wl WARNING: /sys/module/wl/drivers does not exist, cannot rebind wl driver DEBUG: BroadcomWLHandler enabled(): kmod disabled, bcm43xx: blacklisted, b43: blacklisted, b43legacy: blacklisted (repeat of last error several times) Any ideas how to proceed?

• Linking with an image: Background vs <img>

• ROOT_MISMATCH error after following FAQ directions

  - by Adko

  While using Ubuntu One in 11.04 I am unable to change my account info. When I made the switch to 11.04 I forgot that I already had an Ubuntu One account so, I made a new one. However, upon going through one of my email accounts I found my old Ubuntu One login information. I then attempted to switch the account associated with my desktop to my first email. Now, despite following the directions found at https://wiki.ubuntu.com/UbuntuOne/FAQ/WhatToDoWhenSyncdaemonSaysRootMismatch I continue to get the error "File sync error. (local and server roots are different (ROOT_MISMATCH))". Any help would be appreciated.

• Repeater vs. ListView

  - by MoezMousavi

  I do really hate repeater. I was more a GridView lover but after 3.5 be born, I prefer ListView.  The first problem with Repeater is paging. You will need to write code to handle paging. Second common problem is empty data template. Have a look at this:             if (rptMyRepeater.Items.Count < 1)             {                 if (e.Item.ItemType == ListItemType.Footer)                 {                     Label lblFooter = (Label)e.Item.FindControl("lblEmpty");                     lblFooter.Visible = true;                 }             }   I found the above code is usefull if you need to show something like "There is no record" is your data source has no records. Although the ListView has a template.   If you combine ListView with a DataPager, you will be in heaven as it is sorting the paging for you without writing code. (http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.datapager.aspx)     Note: You have got to bind ListView in PreRender, it doesn't work properly in PageLoad   More: http://www.4guysfromrolla.com/articles/061009-1.aspx

• URIs and Resource vs Resource representation

  - by bckpwrld

  URL is an URI which identifies a resource by location. Resource representation is a view of resource's state. This view is encoded in one or more transferable formats, such as XHTML, Atom, XML, MP3 ... URIs associate resource representations with their resources a) So I assume URI identifies a resource and not resource representation? b) I've read that relationship between an URI and resource representation is one to many. Assuming we're talking about URL, how can a single URL address more than one resource representation? thank you

• Error after installing Ubuntu 12.04 using Wubi

  - by KJ50

  After using Windows Ubuntu Installer from within Windows, I am prompted to restart, so I follow the directions. When I try to start Ubuntu after restarting, the desktop background appears, but then a loading bar with this title appears. Verifying the installation configuration... While this is loading, an error window pops up that says No root file system is defined Please correct this from the partitioning menu There is only an 'Ok' button available to click, and if I click that the same error window appears. I do not know how to get to the "partitioning menu" from this state, so the only option I have is to shut down my computer. What can I do so that Ubuntu finds a "root file system"? Can I diagnose this problem via Windows? Does anyone have any insight? FYI - I am using a new ultrabook with 6GB RAM, Intel i7 3rd gen processor, and no CD/DVD drive.
