  • Consistency of DirectX models

    - by marc wellman
    Is there a way to check the consistency of a DirectX model (.x) ? Whilst compiling .x files with XNA GameStudio 3.1 compilation is aborted with the following error message: Error 2 Could not read the X file. The file is corrupt or invalid. Error code: D3DXFERR_PARSEERROR. C:\WFP\Browser\Content\m.x KiviBrowser Some models compile correctly without any error/warning and some abort as described. The files of each model have several thousand lines. I am creating the files in Googles SketchUp 8 where they all look fine and don't show any sign of corruption. Suppose I have such a model my XNA compiler won't compile because their is an inconsistency somewhere in the file - how could I identify this in order to correct it ?

  • The Buzz at the JavaOne Bookstore

    - by Janice J. Heiss
    I found my way to the JavaOne bookstore, a hub of activity. Who says brick and mortar bookstores are dead? I asked what was hot and got two answers: Hadoop in Practice by Alex Holmes was doing well. And Scala for the Impatient by noted Java Champion Cay Horstmann also seemed to be a fast seller. Hadoop in PracticeHadoop is a framework that organizes large clusters of computers around a problem. It is touted as especially effective for large amounts of data, and is use such companies as  Facebook, Yahoo, Apple, eBay and LinkedIn. Hadoop in Practice collects nearly 100 Hadoop examples and presents them in a problem/solution format with step by step explanations of solutions and designs. It’s very much a participatory book intended to make developers more at home with Hadoop.The author, Alex Holmes, is a senior software engineer with more than 15 years of experience developing large-scale distributed Java systems. For the last four years, he has gained expertise in Hadoop solving Big Data problems across a number of projects. He has presented at JavaOne and Jazoon and is currently a technical lead at VeriSign.At this year’s JavaOne, he is presenting a session with VeriSign colleague, Karthik Shyamsunder called “Java: A Perfect Platform for Data Science” where they will explain how the Java platform has emerged as a perfect platform for practicing data science, and also talk about such technologies as Hadoop, Hive, Pig, HBase, Cassandra, and Mahout. Scala for the ImpatientSan Jose State University computer science professor and Java Champion Cay Horstmann is the principal author of the highly regarded Core Java. Scala for the Impatient is a basic, practical introduction to Scala for experienced programmers. Horstmann has a presentation summarizing the themes of his book on at his website. On the final page he offers an enticing summary of his conclusions:* Widespread dissatisfaction with Java + XML + IDEs               --Don't make me eat Elephant again * A separate language for every problem domain is not efficient               --It takes time to master the idioms* ”JavaScript Everywhere” isn't going to scale* Trend is towards languages with more expressive power, less boilerplate* Will Scala be the “one ring to rule them”?* Maybe              --If it succeeds in industry             --If student-friendly subsets and tools are created The popularity of both books echoed comments by IBM Distinguished Engineer Jason McGee who closed his part of the Sunday JavaOne keynote by pointing out that the use of Java in complex applications is increasingly being augmented by a host of other languages with strong communities around them – JavaScript, JRuby, Scala, Python and so forth. Java developers increasingly must know the strengths and weaknesses of such languages going forward.

  • How to merge two .iso images

    - by pgrytdal
    I am following this tutorial to install Android onto my computer VIA Virtual Box. My problem is, they want you to download liveandroidv0.3.iso.001 liveandroidv0.3.iso.002 then they want you to merge these two files with cat liveandroidv0.3.iso.001 liveandroidv0.3.iso.002 > liveandroidv0.3.iso in the Terminal. The problem is, when I run the command, I get the following output cat liveandroidv0.3.iso.001 liveandroidv0.3.iso.002 > liveandroidv0.3.iso cat: liveandroidv0.3.iso.001: No such file or directory cat: liveandroidv0.3.iso.002: No such file or directory So, I was wondering if there was an alternative way to merge these files? Or if you guy's could help me merge them this way? Extra info: OS: Ubuntu 12.10 I downloaded the files to my /downloads folder in my home directory.

  • PLEASE HELP RECOVER MY MINT14 BOOT/GRUB [closed]

    - by C2940680
    Hi I have following from [bootinfoscript][1] v0.61 [1Apr-2012]: I tried to do several time to do a boot-repair from YannUbuntu. However, I get error rebooting into my Linux Mint 14 Cinnamon. I have partitioned /boot, /, /home partitions. Could I still use /home partition if I recover files on to external USB and then reformatting the whole hard drive, repartition and use /home from USB drive which I have saved before? Also, I tried to install Qubes 2beta and then deleted the partition where it was stored. Also, also {my bad} I tried to copy the BOOT.CFG from sda6 to sda1 and sda2.

  • ISO, Six Sigma, SEI-CMM, etc., in Fortune 500 companies

    - by CMR
    Do large corporations and product companies follow any standard quality models/processes at all? For example, I have seen that many large organizations have proprietary processes in IT and software development. Back in the days (even before Motorola's Iridium project,) I remember many IT companies scampering for SEI-CMM certification. Do any of the Fortune 500 company try to adopt these quality processes? In my limited experience I have not seen them undergoing audits for adherence to processes. Most of the audits are either financial, or issues pertaining to legalities. Am I just being ignorant, or is this true? If true, how stringently do the companies adhere to the processes?

  • Can't disable giant cursors (from accessibility mode)

    - by jackweirdy
    I've just installed ubuntu 12.04 from a livecd. Out of curiosity, I enabled the accessibility options for people who are hard of sight. As you can guess this does the usual stuff of inverting colours, increasing text size and making the cursor larger. Having finished the installation I booted into the new system to find accessibility mode was still installed. From the lightdm login screen I disabled this which switched colours and text size back to default, however it's only the pointer cursor that has gone back to default. To put it another way, the "hand" icon that you get when hovering over a link, the cursor which appears when typing and pretty much every other cursor on the system are still large. I've looked on the Universal Access menu, but there's no option to disable large cursors. I've tried toggling accessibility on and off but to no avail.

  • Windows 7 Virtual PC - &ldquo;RPC server unavailable&rdquo;

    - by Kelly Jones
    I use Windows 7 Virtual PC on my current project and I often bring home the files, so I can work some in the evenings.  Since my VHDs are large, I’ll only copy the undo disks, saved state, and virtual machine config files from my external drive.  I copy them to a small portable drive and once I get home, I’ll copy them to a large external drive. I’ve done this for over a year, but recently I started getting an error when I tried to start the VPC after the copying was finished.  It would open the initial window with the progress bar, but eventually the bar would stop, turn red, and then the error “RPC server unavailable” would appear.  When I first started seeing these, I’d try again, but no luck. After some testing, it turns out that my small portable drive is apparently going bad, so it was corrupting the files.  Lucky for me, that I never overwrote my good copies with corrupted copies, at least not at both the office and at home.

  • Share Mulitple Classes as one dll or a lib with Mulitple Projects

    - by JNL
    Currently I have some shared class files(.cpp and .h) which I include them in around 20 Projects. Currently I have to include them in all of the projects. So if I get some business requirments and I change some of the shared(.cpp or .h) files I have to include them in all the 20 Projects which is kind of tedious. Is there a way where I can create a shared dll or library and include it all of my Projects. So if I have to change it, I just have to change it once and then just Add Reference to include that dll or library which contains all the shared(.cpp, .h) files. Any help/recommendations regarding the same, will be highly appreciated. I am using VS2012 for VC++.

  • AngularJS: structuring a web application with multiple ng-apps

    - by mg1075
    The blogosphere has a number of articles on the topic of AngularJS app structuring guidelines such as these (and others): http://www.johnpapa.net/angular-app-structuring-guidelines/ http://codingsmackdown.tv/blog/2013/04/19/angularjs-modules-for-great-justice/ http://danorlando.com/angularjs-architecture-understanding-modules/ http://henriquat.re/modularizing-angularjs/modularizing-angular-applications/modularizing-angular-applications.html However, one scenario I have yet to come across for guidelines and best practices is the case where you have a large web application containing multiple "mini-spa" apps, and the mini-spa apps all share a certain amount of code. I am not referring to the case of trying to have multiple ng-app declarations on the same page; rather, I mean different sections of a large site that have their own, unique ng-app declaration. As Scott Allen writes in his OdeToCode blog: One scenario I haven't found addressed very well is the scenario where multiple apps exist in the same greater web application and require some shared code on the client. Are there any recommended approaches to take, pitfalls to avoid, or good sample structures of this scenario that you can point to?

  • Game Patching Mac/PC

    - by Centurion Games
    Just wondering what types of solutions are available to handle patching of PC/Mac games that don't have any sort of auto updater built into them. In windows do you just spin off some sort of new install shield for the game that includes the updated files, hope you can read a valid registry key to point to the right directory, and overwrite files? If so how does that translate over to Mac where the game is normally just distributed as straight up .app file? Is there a better approach than the above for an already released product? (Assuming direct sells, and not through a marketplace that features auto-updating like Steam.) Are there any off the shelf auto-updater type libraries that could also be easily integrated with a C/C++ code base even after a game has been shipped to make this a lot simpler, and that are cross platform? Also how do auto-updaters work with new OS's that want applications and files digitally signed?

  • What kind of position matches my skills, experience and interests? [closed]

    - by Ryan
    I work in a large firm and my current job covers a variety of different duties. Due to several factors I am seriously considering finding a new job (hours, pay-cut, limited career growth). I have worked for the company nearly 4 years and almost 2 years ago I transitioned into more of a business analyst role (previously I was working in a client facing role for our audit group). In this role I have overseen all aspects of the development of a large scale re-platforming of our firm's key tool in analyzing investment portfolios. I gathered requirements, wrote specs, designed the UI and functionality, worked closely with developers (onshore and offshore) to see to it the implementation was correct, managed schedules and was the lead tester. This is a large scale system used by thousands of people around the world. I've also written Excel macros, reports in SQL, given trainings, written technical manuals, interfaced with senior managers and partners, etc. I've been on a couple interviews sporadically, most of which were for positions aimed at higher management consulting type positions, dealing with strategy, overall process management, project management, etc. What really interests me is the technical stuff and overseeing a project from beginning to end (although I would rather not have to do so many of the tasks on my own). I genuinely like a lot of what I do, but the company culture and attitude towards overworking people combined with my recent pay-cut (my overtime was cut due to a promotion to a higher level) has lead me to want to seek work elsewhere. The problem is - what type of work could I realistically do? I feel like traditional business analysis is too much business and not enough tech stuff, and I've really taken a shine lately to beefing up my programming abilities and creating small programs to automate things around work. I also feel that because my actual years of experience as a business analyst (figure 1.5 years realistically) puts me at a junior level doing a lot of grunt requirements gathering, when the work that I have been doing with my current company is more in line with what a Program Manager does (depending on your definition I guess). So in reality, when I'm job hunting I get a bit perplexed because I feel like the traditional BA stuff wouldn't really suit me, and even if it did it's usually something along the lines of 5-10 years experience for the type of work that is similar to what I've done (and I've also found most BA jobs to be contract only which at the moment I'm not too keen on). Program Manager is something that interests me, but again I feel like the experience is lacking because that's a much more senior position. Am I in some kind of career no-man's land? Any idea what would best suit me given my experience and abilities, as well as my interests? I plan to keep learning programming on the side, but don't expect to get a job being a straight programmer given my relative inexperience with programming.

  • Way to make video-thumbnails generate from VLC instead of Totem?

    - by nick
    I'm suffering from problem that video-thumbnails do not appear in nautilus for some video files. I just found this bug typefinding: some mpeg files are not identified as mpeg files which seems to address the problem. I don't understand the specifics as reported in this bug report, but it sounds like it's a problem with Totem's interaction with Gstreamer. Since all my videos play fine with VLC (and they don't all play with Totem), I don't use Totem very much. Is there a way to make VLC generate the video-thumbnails instead of having to rely on the buggy gstreamer/totem? I made VLC my default video player but this had no effect on the display of video-thumbnails. If Totem can't play the video file, then I get no thumbnail. But VLC can play the videos fine, so why can't VLC create a video-thumbnail for it?

  • Unable to remove some unity lenses

    - by S Prasanth
    I removed the files, video, photos and friends lenses with the following command. sudo apt-get purge unity-lens-files unity-lens-video unity-lens-photos unity-lens-friends Although the corresponding results have disappeared from dash, only the friends tab has been removed. There still are tabs for files, video and photos, albeit empty. How do I remove these empty tabs? I use Ubuntu 13.10 Saucy Salamander. I understand that this issue didn't exist in 12.04. The directory structure of unity lenses seems to have changed from 12.04 to 13.10. Earlier the lenses were stored in /usr/share/unity/lenses/. That isn't the case now, rendering this answer inappropriate: http://askubuntu.com/a/120116/111720

  • Ubuntu Server 12.04 Samba Server timeout

    - by phileaton
    I am a beginner with servers. I checked the error logs for Samba and it appears that Samba is timing out when I transfer large files. I can successfully add PDFs for instance to my file server. However, I tried to add a large 1.2Gb video file and it did not succeed. This is the error in the log: smbd/process.c:244(read_packet_remainder) read_fd_with_timeout failed for client 0.0.0.0 read error = NT_STATUS_CONNECT$ Is there a way I can stop it from timing out? Any pointers would be great! Thanks!

  • What does /dev/null mean in the shell?

    I've started learning bash scripting by using this guide: http://www.tldp.org/LDP/abs/abs-guide.pdf However I got stuck at the first script: cd /var/log cat /dev/null > messages cat /dev/null > wtmp echo "Log files cleaned up." What do lines 2 and 3 do in Ubuntu (I understand cat)? Is it only for other Linux distributions? After running this script as root, the output I get is Log files cleaned up. But /var/log still contains all the files.

  • Best way to load rigid bodies from file

    - by Mel
    I'm trying to switch to bullet for physics simulation. Lemme just say first that I am so pleased with bullet's accuracy and performance. After messing around it for a bit, I'm now trying to load rigid bodies from files. Most of my models are in blender and with some searching, I was able to export them in .bullet format. However, loading the files into bullet doesn't look like an easy task. I've come across this page that points me to a sample application that loads bullet files. But then it goes and says that this loader is just a starting point. Is there any open source library out there that will allow me to load rigid bodies from a file? I don't really wanna spend that much time trying to create my own loader.

  • What causes Multi-Page allocations?

    - by SQLOS Team
    Writing about changes in the Denali Memory Manager In his last post Rusi mentioned: " In previous SQL versions only the 8k allocations were limited by the ‘max server memory’ configuration option.  Allocations larger than 8k weren’t constrained." In SQL Server versions before Denali single page allocations and multi-Page allocations are handled by different components, the Single Page Allocator (which is responsible for Buffer Pool allocations and governed by 'max server memory') and the Multi-Page allocator (MPA) which handles allocations of greater than an 8K page. If there are many multi-page allocations this can affect how much memory needs to be reserved outside 'max server memory' which may in turn involve setting the -g memory_to_reserve startup parameter. We'll follow up with more generic articles on the new Memory Manager structure, but in this post I want to clarify what might cause these larger allocations. So what kinds of query result in MPA activity? I was asked this question the other day after delivering an MCM webcast on Memory Manager changes in Denali. After asking around our Dev team I was connected to one of our test leads Sangeetha who had tested the plan cache, and kindly provided this example of an MPA intensive query: A workload that has stored procedures with a large # of parameters (say > 100, > 500), and then invoked via large ad hoc batches, where each SP has different parameters will result in a plan being cached for this “exec proc” batch. This plan will result in MPA.   Exec proc_name @p1, ….@p500 Exec proc_name @p1, ….@p500 . . . Exec proc_name @p1, ….@p500 Go   Another workload would be large adhoc batches of the form: Select * from t where col1 in (1, 2, 3, ….500) Select * from t where col1 in (1, 2, 3, ….500) Select * from t where col1 in (1, 2, 3, ….500) … Go  In Denali all page allocations are handled by an "Any size page allocator" and included in 'max server memory'. The buffer pool effectively becomes a client of the any size page allocator, which in turn relies on the memory manager. - Guy Originally posted at http://blogs.msdn.com/b/sqlosteam/

  • How to solve linear recurrences involving two functions?

    - by Aditya Bahuguna
    Actually I came across a question in Dynamic Programming where we need to find the number of ways to tile a 2 X N area with tiles of given dimensions.. Here is the problem statement Now after a bit of recurrence solving I came out with these. F(n) = F(n-1) + F(n-2) + 2G(n-1), and G(n) = G(n-1) + F(n-1) I know how to solve LR model where one function is there.For large N as is the case in the above problem we can do the matrix exponentiation and achieve O(k^3log(N)) time where k is the minimum number such that for all km F(n) does not depend on F(n-k). The method of solving linear recurrence with matrix exponentiation as it is given in that blog. Now for the LR involving two functions can anyone suggest an approach feasible enough for large N.

  • php.ini modifications has no effect on joomla

    - by user488736
    I have a netbook with a recently installed ubuntu server 12.04 64-bit. I have (only) installed Joomla on it (version 2.5) and now I am trying to tweak the php.ini settings so I can install jomsocial onto joomla. I have changed these settings: upload_max_filesize = 2M post_max_size = 8M to this: upload_max_filesize = 20M post_max_size = 20M in all php.ini-files in my system. Thats six files, found using 'locate': /etc/php5/apache2/php.ini /etc/php5/cli/php.ini /usr/share/doc/php5-common/examples/php.ini-development /usr/share/php5/php.ini-production /usr/share/php5/php.ini-production-dist /usr/share/php5/php.ini-production.cli I have double-checked that these files actually contain the new settings. Still, joomla does not recognize the new settings, stating that upload_max_filesize is still only 2M and post_max_size is still only 8M The same is true after a complete restart of the server. What am I doing wrong here?

    I accidentally remove all files in /var/cache/ directory with sudo rm -rf command. Now I can not see the files in Trash to bring them back. I would like to know how bad is the situation if these files are removed? does ubuntu going to work normally and recreate the directories in cache again automatically? If not, which directories do I have to create in /var/cache/ manually to let everything work fine? I have already manually made apt and apache2 and debconf in cache directoy but I do not know if I miss more importand directory which needed to be created there. I hope somebody can guide me to fix this issue.
