  • Where can I find free or buy "next-gen" 3D Assets?

    - by Valmond
    Usually I buy 3D Assets from sites like turbosquid.com or similar. My problem is that I have lately implemented glow, normal maps, specular (and specular power) maps and reflection maps and I can't find any models that use those techniques. So where can I find / buy "next gen" assets (at least models/items with a normal map)? I have checked for similar posts but those I found are about either free only or 2D or 'ordinary' 3D so I hope this is not a duplicate.

  • Using a front controller design pattern doesn't allow images to be served

    - by MrMe TumbsUp
    I am currently using a front controller. All requests for my website go through it. I have a problem with image links like: <img src="img/image.jpg" /> Then my front controller will try to dispatch the request to: application/controller/ImgController.php. Then the image won't load. I think it has something to do with the .htaccess file: RewriteEngine On RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ index.php [NC,L]

    - by wang.xueqiang
    After I installed Ubuntu 11.04/11.10 in VirtualBox in Windows 7, I cannot update any software with the error message "failed to download package files". After having googled, I have tried: sudo apt-get update sudo apt-get upgrade changed to another sources But I still got the same error message. And there is no problem with internet connection as i can connect to internet using Firefox in Ubuntu. Any ideas?

  • blender: 3D model from guide images

    - by Stefan
    In a effort to learn the blender interface, which is confusing to say the least, I've chosen to model a model from referrence pictures easily found on the web. Problem is that I can't ( and won't ) get perfect "right", "front" and "top" pictures. Blender only allows you to see the background pictures when in ortographic mode and only from right|front|top, which doesn't help me. How to I proceed to model from non-perfect guide images?

  • Agilist, Heal Thyself!

    - by Dylan Smith
    I’ve been meaning to blog about a great experience I had earlier in the year at Prairie Dev Con Calgary.  Myself and Steve Rogalsky did a session that we called “Agilist, Heal Thyself!”.  We used a format that was new to me, but that Steve had seen used at another conference.  What we did was start by asking the audience to give us a list of challenges they had had when adopting agile.  We wrote them all down, then had everybody vote on the most interesting ones.  Then we split into two groups, and each group was assigned one of the agile challenges.  We had 20 minutes to discuss the challenge, and suggest solutions or approaches to improve things.  At the end of the 20 minutes, each of the groups gave a brief summary of their discussion and learning's, then we mixed up the groups and repeated with another 2 challenges. The 2 groups I was part of had some really interesting discussions, and suggestions: Unfinished Stories at the end of Sprints The first agile challenge we tackled, was something that every single Scrum team I have worked with has struggled with.  What happens when you get to the end of a Sprint, and there are some stories that are only partially completed.  The team in question was getting very de-moralized as they felt that every Sprint was a failure as they never had a set of fully completed stories. How do you avoid this? and/or what do you do when it happens? There were 2 pieces of advice that were well received: 1. Try to bring stories to completion before starting new ones.  This is advice I give all my Scrum teams.  If you have a 3-week sprint, what happens all too often is you get to the end of week 2, and a lot of stories are almost done; but almost none are completely done.  This is a Bad Thing.  I encourage the teams I work with to only start a new story as a very last resort.  If you finish your task look at the stories in progress and see if there’s anything you can do to help before moving onto a new story.  In the daily standup, put a focus on seeing what stories got completed yesterday, if a few days go by with none getting completed, be sure this fact is visible to the team and do something about it.  Something I’ve been doing recently is introducing WIP (Work In Progress) limits while using Scrum.  My current team has 2-week sprints, and we usually have about a dozen or stories in a sprint.  We instituted a WIP limit of 4 stories.  If 4 stories have been started but not finished then nobody is allowed to start new stories.  This made it obvious very quickly that our QA tasks were our bottleneck (we have 4 devs, but only 1.5 testers).  The WIP limit forced the developers to start to pickup QA tasks before moving onto the next dev tasks, and we ended our sprints with many more stories completely finished than we did before introducing WIP limits. 2. Rather than using time-boxed sprints, why not just do away with them altogether and go to a continuous flow type approach like KanBan.  Limit WIP to keep things under control, but don’t have a fixed time box at the end of which all tasks are supposed to be done.  This eliminates the problem almost entirely.  At some points in the project (releases) you need to be able to burn down all the half finished stories to get a stable release build, but this probably occurs less often than every sprint, and there are alternative approaches to achieve it using branching strategies rather than forcing your team to try to get to Zero WIP every 2-weeks (e.g. when you are ready for a release, create a new branch for any new stories, but finish all existing stories in the current branch and release it). Trying to Introduce Agile into a team with previous Bad Agile Experiences One of the agile adoption challenges somebody described, was he was in a leadership role on a team he had recently joined – lets call him Dave.  This team was currently very waterfall in their ALM process, but they were about to start on a new green-field project.  Dave wanted to use this new project as an opportunity to do things the “right way”, using an Agile methodology like Scrum, adopting TDD, automated builds, proper branching strategies, etc.  The problem he was facing is everybody else on the team had previously gone through an “Agile Adoption” that was a horrible failure.  Dave blamed this failure on the consultant brought in previously to lead this agile transition, but regardless of the reason, the team had very negative feelings towards agile, and was very resistant to trying it out again.  Dave possibly had the authority to try to force the team to adopt Agile practices, but we all know that doesn’t work very well.  What was Dave to do? Ultimately, the best advice was to question *why* did Dave want to adopt all these various practices. Rather than trying to convince his team that these were the “right way” to run a dev project, and trying to do a Big Bang approach to introducing change.  He would be better served by identifying problems the team currently faces, have a discussion with the team to get everybody to agree that specific problems existed, then have an open discussion about ways to address those problems.  This way Dave could incrementally introduce agile practices, and he doesn’t even need to identify them as “agile” practices if he doesn’t want to.  For example, when we discussed with Dave, he said probably the teams biggest problem was long periods without feedback from users, then finding out too late that the software is not going to meet their needs.  Rather than Dave jumping right to introducing Scrum and all it entails, it would be easier to get buy-in from team if he framed it as a discussion of existing problems, and brainstorming possible solutions.  And possibly most importantly, don’t try to do massive changes all at once with a team that has not bought-into those changes.  Taking an incremental approach has a greater chance of success. I see something similar in my day job all the time too.  Clients who for one reason or another claim to not be fans of agile (or not ready for agile yet).  But then they go on to ask me to help them get shorter feedback cycles, quicker delivery cycles, iterative development processes, etc.  It’s kind of funny at times, sometimes you just need to phrase the suggestions in terms they are using and avoid the word “agile”. PS – I haven’t blogged all that much over the past couple of years, but in an attempt to motivate myself, a few of us have accepted a blogger challenge.  There’s 6 of us who have all put some money into a pool, and the agreement is that we each need to blog at least once every 2-weeks.  The first 2-week period that we miss we’re eliminated.  Last person standing gets the money.  So expect at least one blog post every couple of weeks for the near future (I hope!).  And check out the blogs of the other 5 people in this blogger challenge: Steve Rogalsky: http://winnipegagilist.blogspot.ca Aaron Kowall: http://www.geekswithblogs.net/caffeinatedgeek Tyler Doerkson: http://blog.tylerdoerksen.com David Alpert: http://www.spinthemoose.com Dave White: http://www.agileramblings.com (note: site not available yet.  should be shortly or he owes me some money!)

  • Do you need to know Java before trying Scala

    - by gizgok
    I'm interested in learning Scala. I've been reading a lot about it, but a lot of people value it because it has an actor model which is better for concurrency, it handles xml in a much better way, solves the problem of first class functions. My question is do you need to know Java to understand/appreciate the way things work in Scala? Is it better to first take a stab at Java and then try Scala or you can start Scala with absolutely no java backround?

  • Convincing my coworkers to use Hudson CI

    - by in0de
    Im really aware of some benefits of using Hudson as CI server. But, im facing the problem to convince my coworkers to install and use it. To put some context, we are developing two different products (one is an enterprise search engine based on Apache Solr) and several enterprise search projects. We are facing a lot of versioning issues and i think Hudson will solve this problems. They argued about its productivity and learning curve What Hudson's benefits would you spotlight?

  • How to get warnings when compiling fx files

    - by jdv-Jan de Vaan
    When I compile DirectX shaders (.fx files), I dont see any compiler warnings unless there was an error in the effect. This happens both when using the offline FXC compiler, as well as calling SlimDx's CompileEffect (which is what we normally do). I could force warnings as errors (/WX), but if you enable that, you get an error that compilation failed, without the warning that caused the problem. So how can I output warnings for shaders that compile properly?

  • andengine - how to make the game wait for an animation to finish?

    - by petervaz
    I'm teaching myself andengine while trying to make a match-3 puzzle, so far I have a grid of gems that I populate and can move then around. Matching gems and new gems falling is working already. My problem is that the game keeps flowing while animations runs. How can I make the flow suspend until movement is done? I use entity modifiers for the gems animations. MoveYModifier for the fall and PathModifier for the swap.

  • Thinkpad brightness steps error using FN+Home/End

    - by petermolnar
    I've met the following problem: normally my T400 (Lenovo Thinkpad) has 16 steps of brightness, and Windows utilizes it correctly. After a fresh install & minor tweaks Mint 12 (which is based on 11.10 Ubuntu) I only had 6 steps which was way to few. Listing /sys/class/backlight showed 3 entried. I removed the acpi-tools package, one of the disapperared - and I now have 10 steps! Therefore I think if I can reduce the entries to 1 I'm going to have 16 steps, since the stepping will be 1 instead of 2 (or 3). /sys/class/backlight/ intel_backlight -> ../../devices/pci0000:00/0000:00:02.0/drm/card0/card0-LVDS-1/intel_backlight thinkpad_screen -> ../../devices/virtual/backlight/thinkpad_screen The problem is that I'm unable to trace back what are the configs / daemons / kernel options triggers these two. More strangely, I discovered a strange behaviour. I monitored watch -n1 "cat /sys/class/backlight/thinkpad_screen/actual_brightness" and watch -n1 "cat /sys/class/backlight/intel_backlight/actual_brightness" while changing the brightness with FN+home/end combinations from max to min. The outcome is the following: brighness intel thinkpad --------- ----- -------- MAX 2408475 7 | 1955115 5 | 1435640 3 | 1246740 1 | 1086175 0 | 1010615 6 | 859495 4 | 689485 2 v 481695 0 MIN 217235 0 brighness intel thinkpad --------- ----- -------- MIN 217235 0 | 481695 2 | 689485 4 | 859495 6 | 1010615 7 | 1086175 1 | 1246740 3 | 1435640 5 v 1955115 7 MAX 2408475 0 When stepping from MIN to MAX, there's no difference between the last 2 steps. Also, the OSD icon (Cinnamon desktop, default theme) goes from full to min in 4 steps and from full to min once again in 4 steps. So... it seems that the intel entry is working correctly, showing correct values. The thinkpad entry however twists the things and even showing incorrect values. Does anyone have any idea how to get rid of the thinkpad entry? System data: Linux Mint 12 3.0.0-16 kernel Lenovo ThinkPad T400 Cinnamon 1.4 desktop For any additional info, please tell me what do you need. EDIT I'm sorry, I forgot to mention, I added acpi_backlight=vendor to GRUB cmdline as well, this is the result of the semi-better working than the default.

  • Installing .NET Framework 4 Client Profile breaks Windows Update

    - by Richard
    I have a Samsung NC-10 netbook with a fresh install of Windows 7 Home Premium 32-bit (it only had 2GB). If Microsoft .NET Framework 4 Client Profile is installed on it, Windows Update will always return error code 8024402F ("Windows Update encountered an unknown error"). As soon as I uninstall it, Windows Update works just fine again. Out of the four computers in this house, only this netbook has the problem. My question is: How can I get the .NET Framework 4 Client Profile installed on my netbook and continue to have a functioning Windows Update? ----- More information ----- The hard-drive recently died on my netbook so I replaced it with a nice new SSD and did a fresh installation of Windows 7 Home Premium (SP1) - along with all the updates. At some point I found that, when I ran Windows Update, I was greeted with error code 8024402F ("Windows Update encountered an unknown error"). Looking in C:\Windows\WindowsUpdate.log, I saw the following issue: WARNING: ECP: Failed to validate cab file digest downloaded from http://download.windowsupdate.com/msdownload/update/software/dflt/2012/02/4913552_4a5c9563d1f58c77f30d0d5c9999e4b8bff3ab21.cab with error 0x80091007 WARNING: ECP: This roundtrip contained some optimized updates which failed. New Update count = 0, Old Count = 3 FATAL: ProcessCoreMetadata did not return any update to be committed WARNING: Sync of Updates: 0x8024402f WARNING: SyncServerUpdatesInternal failed: 0x8024402f When I downloaded the CAB from the URL listed and opened it, it contained a file called 4913552.txt. A search on Google suggested that it's related to Microsoft .NET Framework 4 Client Profile. Other people had reported problems with it breaking Windows Update, but they were running Windows XP. I tried the steps outlined on the Microsoft site for this error code, but it reported that there was nothing wrong. I also found this superuser question, I tried all the answers listed but none of them made any difference. My router doesn't block ActiveX, changing my internet settings in IE made no difference, assuming it was a corrupted update repository didn't do anything (except wipe my update history), my date and time was correct, switching to Google's DNS didn't work and neither did disabling IPv6. Figuring that this update was corrupted, I repaired it and nothing changed. In desperation I un-installed it and Windows Update started working again! Brilliant! I then downloaded the full version from the Microsoft website, installed it and, thankfully, Windows Update continued to work just fine. A week later I turn on my netbook and Windows Update is broken again with exactly the same error message and log entries as before. Repairing .NET Framework 4 Client Profile did nothing, removing it entirely solved the problem again. Thinking this might be some odd Windows installation issue, I formatted the hard-drive and re-installed Windows. Same problem as before - as soon as .NET Framework 4 Client Profile ended up on the netbook, Windows Update stopped working and reported error 8024402F. As soon as it was un-installed, everything worked just fine again. There are three other machines in this house and all of them have working Windows Update and this Client Profile. Does anyone know why it causes this netbook to break and, more importantly, how I can fix it?

  • How to handle interruptions in developer work without losing concentration? [closed]

    - by tomaszs
    I work as a developer for some years now. Mainly the issue why it's antisocial work is because you need to spend much time programming. I've been always the kind of developer who likes to cut off from any sources of distraction and spend several hours on project because in this way i (as i hope) do it faster. There are also other kinds of developers, more social that can chat, read, watch movies while development and they are ok with this and don't hesitate to be interrupted in their work in any time and come back to the project without any problem. For me any distraction is source of frustration because i need to spend substantial time to load my mind with all info about the project and to concentrate back on the tasks. I always thought it's better to do this that way because project is completed faster. But it makes some things difficult: it's hard to chat with someone who needs to have some important info: because you are a bit frustrated when you know you loose your Zen. And sometimes its more important to chat with someone than to loose Zen. Well.. mostly in any other kind of work the ability to be "multitask" is very important. But as a developer and as a person it's also very important to stay social. And i see now that the problem of concentration makes it difficult to make the right chose: the cost of maintaining concentration is just sometimes so damn high! So is it only me that i have so little concentration skills so any interruption is for me a big deal? Maybe it's just i have so bad memory so that i dont remember all issues of a project so long? Or maybe i develop the project in a fashion that requires me to store so much info on my mind only to be able to start working with code? Or should i just accept that being more social will make me finish project slower and in the fashion that i personally consider non 100% productive? And it's just normal thing and i should just accept it and start to live like any other person who has many works and don't assume that programming is in any case other than any other work and i just do fuzz about the whole concentration thing? This is question for mid-pro developers. I think you was having the same dillema in your life. I would be glad if you could help me take the right road here because it's just driving me and i suppose people i work with crazy for years.

  • Rails - How to use modal form to add object in one model, then reflect that change on main page?

    - by Jim
    I'm working on a Rails app and I've come across a situation where I'm unsure of the cleanest way to proceed. I posted a question on SO with code samples and such - it has received no answers, and the more I think about the problem, the more I think I might be approaching this the wrong way. (See the SO question at http://stackoverflow.com/questions/9521319/how-to-reference-form-when-rendering-partial-from-js-erb-file) So, in more of a generic architecture type question: Right now I have a form where a user can add a new recipe. The form also allows the user to select ingredients (it uses a collection_select which contains Ingredient.all). The catch is - I'd like the user to be able to add a new ingredient on the fly, without leaving the recipe form. Using a hidden div and some jQuery/AJAX, I have a link the user can click to popup a modal form containing ingredients/new.html.erb which is a simple form. When that form is submitted, I call ingredients/create.js.erb to validate the ingredient was saved and hide the modal div. Now I am back to my recipe form, but my collection_select hasn't updated. It seems I have a few choices here: try and re-render the collection_select portion of the form so it grabs a new list of ingredients. This was the method I was attempting when I wrote the SO question. The problem I run into is the partial I use for the collection_select needs the parent form passed in, and when I try and render from the JS file I don't know how to pass it the form object. Reload the recipe form. This works (the collection_select now contains the new ingredient), but the user loses any progress they made on the recipe form. I would need a way to persist the form data - I thought about manually passing the values back and forth, but that is sloppy and there has to be a better way... Try and manually insert the tags using jQuery - this would be simple, but because I'm allowing for multiple ingredients to be added, I can't be certain what ID to target. Now, I can't be the only person to have this issue - so is there an easier way I'm missing? I like option 2 above, but I don't know if there's an easy way to grab the entire params hash as if I had submitted the main recipes form. Hopefully someone can point me in the right direction so I can find an answer to this... If this doesn't make any sense at all, let me know - I can post code samples if you want, but most of the pertinent code is up on the SO question. Thanks!

    I decided to wipe Windows 7 and made a full installation. Everything works great but for a Encore N300 wireless usb dongle that I use on my desktop. Ubuntu seems to recognize it and I can browse the available networks, but I can connect to any of them. I was told that I should download its drivers, and so I did it, but I don't know how to install them. Please, I'd like to know if my connectivity problem is really a driver issue or some other thing.

  • How to diagnose computer lockups and freezes?

    - by Scott Mitchell
    I built a desktop computer a couple years back with the following specs: CPU: Intel Core 2 Quad Q9300 Yorkfield 2.5GHz 6 MB L2 Cache LGA 775 95W Quad-Core Processor BX80580Q9300 Motherboard: EVGA 122-CK-NF68-T1 LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard Video Card: Two EVGA 256-P2-N758-TR GeForce 8600GT SCC 256 MB 128-bit GDDR3 PCI Express x16 SLI Supported Video Card PSU: SeaSonic S12 Energy Plus SS-550HT 550W ATX12V V2.3 / EPS12V V2.91 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC Power Supply Memory: Two G.SKILL 4 GB (2 x 2 GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL5D-4GBPQ Since its inception, the machine has periodically locked up, the regularity having varied over the years from once a day to once a month. Typically, lockups happen once every few days. By "lockup" I mean my computer just freezes. The screen locks up, I can't move the mouse. Hitting keys on my keyboard that normally turn LEDs on or off on the keyboard (such as Caps Lock) no longer turn the LEDs on or off. If there was music playing at the time of the lockup, noise keeps coming out of the speakers, but it's just the current frequency/note that plays indefinitely. There is no BSOD. When such a lockup occurs I have to do a hard reboot by either turning off the computer or hitting the reset button. I have the most recent version of the NVIDIA hardware drivers, and update them semi-regularly, but that hasn't seemed to help. I am currently using Windows 7 x64, but was previously using Windows Server 2003 x64 and having the same lockup issues. My guess is that it's somehow video driver or motherboard related, but I don't know how to go about diagnosing this problem to narrow down which of the two is the culprit. Additional information re: cooling Regarding cooling... I've not installed any after-market cooling systems aside from two regular fans I scavenged from an older computer. The fan atop the CPU is the one that shipped with it. One of the two scavenged fans I added it located at the bottom tower of the corner, in an attempt to create some airflow from front to back. The second fan is pointed directly at the two video cards. SpeedFan installation and readings Per studiohack's suggestion, I installed SpeedFan, which provided the following temperature readings: GPU: 63C GPU: 65C System: 76C CPU: 64C AUX: 36C Core 0: 78C Core 1: 76C Core 2: 79C Core 3: 79C Update #3: Another Lockup :-( Well, I had another lockup last night. :-( SpeedFan reported the CPU temp at 38 C when it happened, and there was no spike in temperature leading up to the freeze. One thing I notice is that the freeze seems more likely to happen if I am watching a video. In fact, of the last 5 freezes over the past month, 4 of them have been while watching a video on Flickr. Not necessarily the same video, but a video nevertheless. I don't know if this is just coincidence or if it means anything. (As an aside, each night before bedtime my 2 year old daughter sits on my lap and watches some home videos on Flickr and, in the last month, has learned the phrase, "Uh oh, computer broke.") Update #4: MemTest86 and 3DMark06 Test Results: Per suggestions in the comments, I ran the MemTest86 overnight and it cycled through the 8 GB of memory 5 times without error. I also ran the 3DMark06 test without a problem (see my scores at http://3dmark.com/3dm06/15163549). So... what now? :-) Any further suggestions on what to check? Is there some way to get a stack trace or something when the computer locks like that? Resolution I have never did figure out the particular problems, but based on the suggestions here and elsewhere, I'm presuming it was a motherboard issue. In any event, I recently upgraded my system, buying a new motherbeard, PSU, CPU, and RAM, and that new rig has been working splendidly the past several weeks. I am using the same graphic cards as in the old setup, so I think it's safe to reason that they weren't the cause of the problem.

  • Low graphics mode error on startup with NVIDIA graphics (12.04 LTS )

    My problem is similar to two other posts concerning ATI cards and 12.04 LTS: Post1 & Post2. In my case I use a Dell Precision M4300 laptop which uses a NVidia Quadro FX 880M. Doing a lspci | grep VGA gave me this: 01:00.0 VGA compatible controller: NVIDIA Corporation GT216 [Quadro FX 880M] (rev a2) My workaround consists of logging in at the console and running sudo start lightdm which works perfectly but I am looking for a better workaround than this ?

  • 3D terrain map with Hexagon Grids (XNA)

    - by Rob
    I'm working on a hobby project (I'm a web/backend developer by day) and I want to create a 3D Tile (terrain) engine. I'm using XNA, but I can use MonoGame, OpenGL, or straight DirectX, so the answer does not have to be XNA specific. I'm more looking for some high level advice on how to approach this problem. I know about creating height maps and such, there are thousands of references out there on the net for that, this is a bit more specific. I'm more concerned with is the approach to get a 3D hexagon tile grid out of my terrain (since the terrain, and all 3d objects, are basically triangles). The first approach I thought about is to basically draw the triangles on the screen in the following order (blue numbers) to give me the triangles for terrain (black triangles) and then make hexes out of the triangles (red hex). http://screencast.com/t/ebrH2g5V This approach seems complicated to me since i'm basically having to draw 4 different types of triangles. The next approach I thought of was to use the existing triangles like I did for a square grid and get my hexes from 6 triangles as follows http://screencast.com/t/w9b7qKzVJtb8 This seems like the easier approach to me since there are only 2 types of triangles (i would have to play with the heights and widths to get a "perfect" hexagon, but the idea is the same. So I'm looking for: 1) Any suggestions on which approach I should take, and why. 2) How would I translate mouse position to a hexagon grid position (especially when moving the camera around), for example in the second image if the mouse pointer were the green circle, how would I determine to highlight that hexagon and then translating that into grid coordinates (assuming it is 0,0)? 3) Any references, articles, books, etc - to get me going in the right direction. Note: I've done hex grid's and mouse-grid coordinate conversion before in 2d. looking for some pointers on how to do the same in 3d. The result I would like to achieve is something similar to the following: http :// www. youtube .com / watch?v=Ri92YkyC3fw (sorry about the youtube link, but it will only let me post 2 links in this post... same rep problem i mention below...) Thanks for any help! P.S. Sorry for not posting the images inline, I apparently don't have enough rep on this stack exchange site.
