  • Apache htaccess results in files being downloaded instead of displayed

    - by chrissik
    So I had this "beautiful" website that did exactly what I wanted it to do. Then I shut down my PC, reboot and...the pages just download now instead of being displayed. I re-installed XAMPP and launched Apache again and I was able to identify the .htaccess file as the cause of the problem. Options +FollowSymlinks RewriteEngine on RewriteCond %{QUERY_STRING} !^desktop RewriteCond %{HTTP_USER_AGENT} "android|blackberry|googlebot-mobile|iemobile|iphone|ipod|#opera mobile|palmos|webos" [NC] RewriteRule ^/?$ /mobile/index [L,R=302] RewriteRule ^/?$ /de/index [R] RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.html -f RewriteRule ^(.*)$ $1.html Here is the problem I guess: RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.html -f RewriteRule ^(.*)$ $1.html This should make it possible to use /de/index instead of /de/index.html - but somehow it causes the page to download if I open localhost/de/index (but with localhost/de/index.html it works fine...). I'm using HTML Sites with SSI Elements on a Apache web server. The only other file that is different to the out-of-the-box ones is the httpd.conf, where I enabled SSI: AddType text/html .shtml AddHandler server-parsed .shtml AddHandler server-parsed .html AddHandler server-parsed .htm Options Indexes FollowSymLinks Includes AddOutputFilter INCLUDES .shtml Options +Includes So I hope there is somebody among you that can help me with this annoying problem as I'm quite desperate... for some reason, even without the problematic lines Chrome keeps downloading the files (even if I delete the .htaccess file), while IE and Opera display the pages. Edit: Now Opera also wants to download files (whether index.html or index are called).

  • Why can't we capture the design of software more effectively?

    - by Ira Baxter
    As engineers, we all "design" artifacts (buildings, programs, circuits, molecules...). That's an activity (design-the-verb) that produces some kind of result (design-the-noun). I think we all agree that design-the-noun is a different entity than the artifact itself. A key activity in the software business (indeed, in any business where the resulting product artifact needs to be enhanced) is to understand the "design (the-noun)". Yet we seem, as a community, to be pretty much complete failures at recording it, as evidenced by the amount of effort people put into rediscovering facts about their code base. Ask somebody to show you the design of their code and see what you get. I think of a design for software as having: An explicit specification for what the software is supposed to do and how well it does it An explicit version of the code (this part is easy, everybody has it) An explanation for how each part of the code serves to achieve the specification A rationale as to why the code is the way it is (e.g., why a particualr choice rather than another) What is NOT a design is a particular perspective on the code. For example [not to pick specifically on] UML diagrams are not designs. Rather, they are properties you can derive from the code, or arguably, properties you wish you could derive from the code. But as a general rule, you can't derive the code from UML. Why is it that after 50+ years of building software, why don't we have regular ways to express this? My personal opinion is that we don't have good ways to express this. Even if we do, most of the community seems so focused on getting "code" that design-the-noun gets lost anyway. (IMHO, until design becomes the purpose of engineering, with the artifact extracted from the design, we're not going to get around this). What have you seen as means for recording designs (in the sense I have described it)? Explicit references to papers would be good. Why do you think specific and general means have not been succesful? How can we change this?

  • How do I get same scrollbar style for gtk-2.0 and gtk-3.0 apps?

    - by David López
    Sorry for my English mistakes, I'm Spanish. I'm using Ubuntu 11.10 in a tablet. I've removed overlay-scrollbars and I have increased the scrollbars size to use them with fingers. In /usr/share/themes/Ambiance/gtk-2.0/gtkrc I've changed: GtkScrollbar::slider-width = 23 GtkScrollbar::min-slider-length = 51 and added: GtkScrollbar::has-backward-stepper = 0 GtkScrollbar::has-forward-stepper = 0 In /usr/share/themes/Ambiance/gtk-3.0/gtk-widgets.css I've changed: GtkScrollbar-min-slider-length: 51; GtkRange-slider-width: 23; (in .scrollbar item) Now my scrollbars are usable with fingers, but they seem different for gtk-2.0 and gtk-3.0 apps. In the picture the left scrollbar is a gtk-2.0 app and the right one is a gtk-3.0 I want to setup gtk2.0 bar to be exactly the same as gtk3.0, that is Make upper and lower extremes empty (oranges circles in the picture) Reduce the length of the 3 horizontal lines (black ellipse) Can somebody help me? Thanks. Hola. Uso ubuntu 11.10 en una tableta; he quitado overlay-scrollbars y he incrementado el tamaño de las barras para poder usarlas con los dedos. Concretamente en /usr/share/themes/Ambiance/gtk-2.0/gtkrc be cambiado GtkScrollbar::slider-width = 23 GtkScrollbar::min-slider-length = 51 y añadido GtkScrollbar::has-backward-stepper = 0 GtkScrollbar::has-forward-stepper = 0 En /usr/share/themes/Ambiance/gtk-3.0/gtk-widgets.css he cambiado GtkScrollbar-min-slider-length: 51; GtkRange-slider-width: 23; (en el apartado.scrollbar) Mis barras son manejables con dedos, pero se ven muy distintas para aplicaciones gtk-2.0 y gtk-3.0.

  • Make Google Plus One only work for the domain and not the path [closed]

    - by Saeed Neamati
    Possible Duplicate: Make Google +1 button +1 a specific URL rather than the URL it's on? I'm creating an image sharing website, and since it's going to have many thousand links, then it's almost impossible to put a Google Plus One button in my site. Plus one is an indication of site's popularity and trust. You follow a link in SERP, because you see that somebody that you know has already plused one that link. So, you trust that link and click it. The more plus a page get, the more trustworthy it becomes. Sites which has simple static pages can get many plus ones, but sites like mine (dynamic sites with thousands of links) can't aggregate plus ones in one page. Is there any way to tell Google that I only want the Plus Ones to be counted for the domain only, and not for the path? In other words, how can I transfer a plus one given to the http://example.com/tag1-tag2/2525 to plus ones given to the http://example.com? Is it possible at all?

  • apache2 is making my amazon ec2 unavailable, any ideas?

    - by Tim
    I have a web server running on a EC2 c1.medium intance. The instance is running on ubuntu, with apache2 and mysql.The ubuntu and apache version are the next; Ubuntu DISTRIB_ID=Ubuntu DISTRIB_RELEASE=11.04 DISTRIB_CODENAME=natty DISTRIB_DESCRIPTION="Ubuntu 11.04" Apache2 Server version: Apache/2.2.17 (Ubuntu) Server built: Feb 22 2011 18:33:02 Sometimes randomly, my server "hangs up", I cannot connect to it using normal web access or ssh access. If I reboot the instance it reboots fine, the amazon system log doesn't show anything weird, but the problem persists The only way to solve it its stopping the instance, and start it again. I think that the problem its has something to do with apache, because the last lines of the error log lists: normal errors [Sun Jun 19 06:25:09 2011] [notice] Apache/2.2.17 (Ubuntu) PHP/5.3.5-1ubuntu7.2 with Suhosin-Patch configured -- resuming normal operations nobody cant connetc... no more erros until i stop and start the instance normal errors [Wed Jun 22 14:21:18 2011] [notice] Apache/2.2.17 (Ubuntu) PHP/5.3.5-1ubuntu7.2 with Suhosin-Patch configured -- resuming normal operations nobody cant connetc... no more erros until i stop and start the instance Can somebody please help me?

  • How advanced are author-recognition methods?

    - by Nick Rtz
    From a written text by an author if a computer program analyses the text, how much can a computer program tell today about the author of some (long enough to be statistically significant) texts? Can the computer program even tell with "certainty" whether a man or a woman wrote this text based solely on the contents of the text and not an investigation such as ip numbers etc? I'm interested to know if there are algorithms in use for instance to automatically know whether an author was male or female or similar characteristics of an author that a computer program can decide based on analyses of the written text by an author. It could be useful to know before you read a message what a computer analyses says about the author, do you agree? If I for instance get a longer message from my wife that she has had an accident in Nigeria and the computer program says that with 99 % probability the message was written by a male author in his sixties of non-caucasian origin or likewise, or by somebody who is not my wife, then the computer program could help me investigate why a certain message differs in characteristics. There can also be other uses for instance just detecting outliers in a geographically or demographically bounded larger data set. Scam detection is the obvious use I'm thinking of but there could also be other uses. Are there already such programs that analyse a written text to tell something about the author based on word choice, use of pronouns, unusual language usage, or likewise?

  • Graphic Card Installation Failure (NV 9600M GT)

    - by Georg
    I wanted to switch from 7 to Ubuntu. Now, the first thing that holds me back is the installation of the driver for my Nvidia 9600M GT. Ubuntu recommends me 4 drivers from the "Additional Driver" Section. Now, whatever driver I install, there are four things happening RANDOMLY after rebooting: The pc freezes before seeing bootup splash The pc freezes while seeing bootup splash image (ubuntu logo with the 5 dots) The pc gets into login screen and freezes instantly (Thought the unity-bar is transparent now) The pc freezes right after beeing able to login. (While this is happening the unity-bar changes from transparent to ugly-flat-style) I also tried to install the official Nvidia .run file but after exiting the X-Server, it says the driver is not compatible with the kernel and exits installation. Can somebody help me? I really wanna get rid of Windows :( But Ubuntu drives me perfectly insane. Please answer as noobish as possible. I'm an expert Windows user, but Linux is absolutely new to me. My Specs: Ubuntu 11.10 installed from USB Stick (like 100 times now :/ because I dont know how to remove the driver in recovery mode) 9600M GT 4GB Ram Intel Centrino 2 Dual Core 2.26GHz Win 7 and Ubuntu running along side. Thank you in advance, regards.

  • How do I boot into console mode (redux)

    - by Leo Simon
    I'm running Ubuntu 12.04. This question was asked some time ago How do I disable the boot splash screen? but the answers didn't work for me. The standard way to boot into console mode used to be to edit /etc/default/grub and set GRUB_CMDLINE_LINUX_DEFAULT="text" This worked fine until I ran the fix proposed in https://help.ubuntu.com/community/SoundTroubleshootingProcedure in order to get sound to work. Since then, I have disabled the boot-splash-screen, but I can avoid what I presume is the lightdm login prompt screen. All I want to do is disable this gui and be prompted with a console login prompt. (Shouldnt be so hard should it???) I read in three 33416 mentioned above that there was a bug in lightdm (it wasn't recognizing "text" properly as an option for GRUB_CMDLINE_LINUX_DEFAULT.) But this discussion happened more than a year ago, and it's surely been fixed. Yet my lightdm is uptodate (so I'm told when I try to update it with apt-get). As suggested in one of the above, I tried sudo update-rc.d -f lightdm remove which resulted in a hung machine. I managed to recover using recovery mode, but now I still get the gui again. Another suggestion is to edit /etc/init/lightdm.override. I've done this and set it to "manual" as suggested, but lightdm simply ignores this. Could somebody suggest how to proceed please? Thanks very much, Leo

  • Web to Print system - which client side technology should I use

    - by mr null
    I'm getting started to develop Web to Print system. My main concern is which client-side techology should I use: jQuery/CSS Flex/ActionScript or something else? For now, idea is that user/customer choose Product eg: Business card Attributes: Dimensions,Paper type, ... etc Template or blank Adjust product (editor) Preview & order Output should be PDF 300dpi. My main issue is: adding/adjusting text in editor. (font size, font family...). Because application should be cross browser. And I think that 10px Arial can't be the same in Firefox 5 and IE 8. It must be pixel perfect in every browser. If somebody order $100 of business cards, and text is different that he/she saw when ordering - that is a big problem. So, Flash platform should be the answer. But, as I see it's dying technology, 2012 is here - HTML5 is replacing Flash rapidly. I hope that you understand me, so every guideline or few smart words would be very appreciating.

    - by Gilberto Albino
    there! I am scared here! I am a Windows 7 User and decided to install Ubuntu 12.04 on my Notebook Dell Inspiron N5110 and when the Grub loads with the menu list the fan starts speeding up. If I choose windows the fan is noiseless but if I choose Ubuntu... Gosh!!! It continues speeding up and overheating... I'm very sad about that! Every time I try to use Linux... I get a diferent hardware issue related to incompatibility or bugs! When it's not graphic driver it is bug elsewhere unimaginable!!! If there is a solution for this... I wonder if someone could spend some time helping me out because... I have JUST bought this notebook because it is in the list of Certified Hardware: http://www.ubuntu.com/certification/hardware/201012-6931/ So this is sad and somehow disgusting! Linux is going for the wrong way! It's never gonna be popular while doesn't have so wide hardware support like WIndows! That's a pitty! It's very likely I won't get answered meanwhile I will switch back for windows! I prefer paying my Windows License and having a fully working system than having a free open source software that is about to explode my notebook or toast my hands before!

  • Ubuntu Server 12.04 as a router. Problem with DNS

    - by Lorenzo
    I have a virtualbox lab made up of 4 Windows 2008 R2 servers (DC/DNS,SQL,SHAREPOINT, EXCHANGE) that are configured with static ip addresses with NIC's attached to Internal network. Everything works. I had the requirement to execute some tests that also access external services available on the internet. To keep things clean and similar to the production environment I have installed another VM, with Ubuntu Server 12.04 64 bit and configured (I hope) to work as a router like described on this post. This VM has two network interfaces: first is Bridged with the host and is used as a WAN connection and the other one attached in the Internal Network with its own static IP address on the internal network subnet. But actually the Windows servers does not connect to the internet while the unix one connects. I did a route command. this is the result: Kernel IP Routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 10.69.121.1 0.0.0.0 UG 100 0 0 eth0 10.69.121.0 * 255.255.255.0 U 0 0 0 eth0 192.168.83.0 * 255.255.255.0 U 0 0 0 eth1 Can somebody help me with this configuration? :) Thanks! Addendum: I forgot to mention that one of the windows server hosts a DNS service for which I should maybe configure a forwarding server but I do not exactly know which server to forward on... :(

  • Social IT guy barrier [closed]

    - by sergiol
    Possible Duplicate: How do you deal with people who ask you to fix their computer? Hello. Almost every person that deserves the title of being a programmer as faced the problem of persons that do not even remember the mere existence of those professionals, unless they have serious problems in their computer or some other IT related problem. May be my post will be considered off-topic, but I think it is a very important question. As Joel Spolsky says, IT guys are not Asperger geeks, and they need social life like everybody. But the people that is always asking for favors from us, can ruin deeply our social and personal life. I could experience this by myself. This fact as generated articles like http://www.lifereboot.com/2007/10-reasons-it-doesnt-pay-to-be-the-computer-guy/ and http://ecraazul.wordpress.com/2009/01/29/o-gajo-da-informatica-de-a-a-z/ (I received this one in my mailbox. It is in Portuguese, but I believe it is translated from English). Basically the idea is to criticize people that is always asking us favors. It is even more annoying if you are person very specialized in some subject and a person asks you a completely out-of-that-context question. For example, you are a VBA programmer and somebody says you to that his/her Mobile Internet Pen stopped to work five days ago and needs your help to put it working again. When you go to a doctor to fix your legs, you don't go to an ophthalmologist. You go to an orthopedist. And you pay. I don't how it works in other countries, but in Portugal being a doctor is so an overvalued job, that they earn very much money and almost nobody asks them free favors. So, my question is: what kind of social barrier (or whatever else) do you use to protect yourself from that situation?

  • Google music search: a better way to listen.

    - by anirudha
    somebody who want to listen music  pay much more to some online music store for online listening. otherwise they experience bad or low quality on YouTube. who is illegal  because uploader not have a permission or right to upload the document and their is no guarantee that they not put their ads or quality as same. now forget YouTube and all other because Google music search is much better just go their search the song by movies name or song and just click and listen. the quality is much better then other but it is not Google. the result they put comes from other website. i feel a thing goes wrong in Google music  search  that if i search “sajda” they never show me result about “sadka” because the word in common life use as same both. but the song may be starting from  “sajda” or “sadka”. i thing that they put the link that Do you means “Sadka” when i search sajda that it is better thing just like many online book store show the different keyword related to your keyword when you search their. like you search for a book on online book store they show you some different keyword when they serve the result and show related product or books when you go to a product page. after thinking all it is a better option for user to feel a better quality music without search hassle.

  • Troubleshooting Your Network with Oracle Linux

    - by rickramsey
    Are you afraid of network problems? I was. Whenever somebody said "it's probably the network," I went to lunch. And hoped that it was fixed by the time I got back. Turns out it wasn't that hard to do a little basic troubleshooting Tech Article: Troubleshooting Your Network with Oracle Linux by Robert Chase You're no doubt already familiar with ping. Even I knew how to use ping. Turns out there's another command that can show you not just whether a system can respond over the network, but the path the packets to that system take. Our blogging platform won't allow me to write the name down, but I can tell you that if you replace the x in this word with an e, you'll have the right command: tracxroute Once you get used to those, you can venture into the realms of mtr, nmap, and netcap. Robert Chase explains how each one can help you troubleshoot the network, and provides examples for how to use them. Robert is not only a solid writer, he is also a brilliant motorcyclist and rides an MV Augusta F4 750.

  • A few unpleasant facts about Visual Studio 2012.

    - by Ilya Verbitskiy
    I have been playing with Visual Studio 2012 for the last couple of days. New IDE is pretty good, but, unfortunately, I found a few unpleasant facts. First of all, new release is coming without Visual Studio setup projects. I am disappointed, because I am using it for my pet project – Easy Shutdown. The tool is a small widget-like application which allows you to reboot, log out or shut down you PC. I have not done any decision yet, but I would probably migrate to WiX. The second surprise is Microsoft will not add Visual Studio macros to the next release. Since I am lazy guy, I like small hacks using macros. For example I have macros to refresh all projects or attach to IIS.  The only way how to solve the problem is to convert your macros to Visual Studio plugin. I have not tried it yet, but I will definitely do in the nearest future. The third fact, I do not like, is Visual Studio default themes. May be somebody like it, but they are hard to adopt after Visual Studio 2010. Fortunately there is a solution. Matthew Johnson released Visual Studio 2012 Color Theme Editor. It comes with a few predefined themes. I really like the Blue one.

  • Stop YOUR emails from starting those company-wide Reply All email threads

    - by deadlydog
    You know you’ve seen it before; somebody sends out a company-wide email (or email to a large diverse audience), and a couple people or small group of people start replying-all back to the email with info/jokes that is only relative to that small group of people, yet EVERYBODY on the original email list has to suffer their inbox filling up with what is essentially spam since it doesn’t pertain to them or is something they don’t care about. A co-worker of mine made an ingenious off-hand comment to me one day of how to avoid this, and I’ve been using it ever since.  Simply place the email addresses of everybody that you are sending the email to in the BCC field (not the CC field), and in the TO field put your email address.  So everybody still gets the email, and they are easily able to reply back to you about it.  Note though, that the people you send the email to will not be able to see everyone else that you sent it to. Obviously you might not want to use this ALL the time; there are some times when you want a group discussion to occur over email.  But for those other times, such as when sending a NWR email about the car you are selling, asking everyone what a good local restaurant near by is, collecting personal info from people, or sharing a handy program or trick you learnt about (such as this one ), this trick can save everybody frustration and avoid wasting their time.  Trust me, your coworkers will thank you; mine did

  • Search inside Xournal files (.xoj)

    - by Javad Sadeqzadeh
    I'm a big fan of Evernote, I use it regularly. However, it has a 60MB storage limit (although text files are not going to occupy much space, but the limitation concern still remains). Today, I installed Xournal, which has great features like annotating, nice background, free hand shapes and notes, save in PDF format, and many more. But the big problem is that as far as I've noticd, there is no intrinsic feature for seach inside the notes (created using Xournal with .xoj suffix). I used Catfish File Search application (which creates bash commands for full text search), but it couldn't help as well. Is there anyway to search inside a .xoj file at all? If so, it could be a suitable alternative to evernote, if you put your .xoj files on a cloud (which certainly offers you much more storage space than 60MB). If not, is there any other convenient app similar to Evernote, but with higher storage limit or without a limit? Somebody suggested Zim desktop wiki app, which looks great, but I'm nut sure if I could copy and paste everything there (a mixture of photos and tables and text with various formats and highlights), like what I do with Evernote. And a very useful tool I use is Evernote Web Clipper (browser extension). Of course, having a desktop client like Everpad is a plus, but not the absolute need. PS: I use pocket, so please do suggest that (it only preserve links (which might change over time) not the actual text). I also use google drive or docs, I don't like that for this purpose niether, it's too slow, doesn't have a browser extension and a desktop client. Thank you so much in advance.

  • How to Manage Technical Employees

    - by Ajarn Mark Caldwell
    In my current position as Software Engineering Manager I have been through a lot of ups and downs with staffing, ranging from laying-off everyone who was on my team as we went through the great economic downturn in 2007-2008, to numerous rounds of interviewing and hiring contractors, full-time employees, and converting some contractors to employee status.  I have not yet blogged much about my experiences, but I plan to do that more in the next few months.  But before I do that, let me point you to a great article that somebody else wrote on The Unspoken Truth About Managing Geeks that really hits the target.  If you are a non-technical person who manages technical employees, you definitely have to read that article.  And if you are a technical person who has been promoted into management, this article can really help you do your job and communicate up the line of command about your team.  When you move into management with all the new and different demands put on you, it is easy to forget how things work in the tech subculture, and to lose touch with your team.  This article will help you remember what’s going on behind the scenes and perhaps explain why people who used to get along great no longer are, or why things seem to have changed since your promotion. I have to give credit to Andy Leonard (blog | twitter) for helping me find that article.  I have been reading his series of ramble-rants on managing tech teams, and the above article is linked in the first rant in the series, entitled Goodwill, Negative and Positive.  I have read a handful of his entries in this series and so far I pretty much agree with everything he has said, so of course I would encourage you to read through that series, too.

  • Collision detection in 3D space

    - by dreta
    I've got to write, what can be summed up as, a compelte 3D game from scratch this semester. Up untill now i have only programmed 2D games in my spare time, the transition doesn't seem tough, the game's simple. The only issue i have is collision detection. The only thing i could find was AABB, bounding spheres or recommendations of various physics engines. I have to program a submarine that's going to be moving freely inside of a cave system, AFAIK i can't use physics libraries, so none of the above solves my problem. Up untill now i was using SAT for my collision detection. Are there any similar, great algorithms, but crafted for 3D collision? I'm not talking about octrees, or other optimalizations, i'm talking about direct collision detection of one set of 3D polygons with annother set of 3D polygons. I thought about using SAT twice, project the mesh from the top and the side, but then it seems so hard to even divide 3D space into convex shapes. Also that seems like far too much computation even with octrees. How do proffessionals do it? Could somebody shed some light.

  • The best way to structure/design game code

    - by Edward
    My question is quite broad and related to the 2D game code design/architecture/structure. Usually the main game consists of the main loop where you update & render your world states. However, it's recommended for many purposes to separate rendering from the game-logic and so on. I am kinda confused about the whole situation. Many game engines/libs/sdks don't follow separation schema. They propagate a way where you define some scenes/stages and they contain some objects and the scene/stage controls the user input and so on. For example, in cocos2d(-x) and libgdx (stage2d) the games are usually done the way that the update logic happens at the same time/place as rendering. Also, the propagated way is to have a structure where an object knows how to draw itself - which is not a separation of updating & rendering. The same with Flash based games, they are usually done the way when an object (class) contains a swf or a texture and some data and holds some update logic itself, or updated from main Scene. And again this object already knows how to draw itself via "addChild". Also, some people recommend to use MVC pattern, which will require to completely obey the structure of those engines/libs/sdks. Maybe I am overthinking everything, but I am totally confused. I would be grateful if somebody could point me to a correct direction with the game code structures. What is your way of doing things in libgdx/cocos2d/flash?

  • What's wrong with my ext4 partition?

    What is wrong with this picture? Top is output from "df -h", bottom is gparted. I suspect I'm missing a lot of free space. No problems other than that (yet). Can somebody suggest the best (non-destructive) way to correct this? sudo dumpe2fs -h /dev/sda3: (source http://pastebin.com/nAvrdT4E) Filesystem volume name: <none> Last mounted on: / Filesystem UUID: 9f6eff64-60d7-4eec-81d5-1e8acd818b38 Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery extent flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize Filesystem flags: signed_directory_hash Default mount options: (none) Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 1602496 Block count: 6406144 Reserved block count: 320306 Free blocks: 4842284 Free inodes: 1361222 First block: 0 Block size: 4096 Fragment size: 4096 Reserved GDT blocks: 1022 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 8176 Inode blocks per group: 511 RAID stride: 32692 Flex block group size: 16 Filesystem created: Sun Nov 8 18:18:13 2009 Last mount time: Tue Mar 1 01:04:27 2011 Last write time: Mon Feb 28 04:27:34 2011 Mount count: 16 Maximum mount count: 28 Last checked: Thu Feb 24 06:23:39 2011 Check interval: 15552000 (6 months) Next check after: Tue Aug 23 07:23:39 2011 Lifetime writes: 227 GB Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 256 Required extra isize: 28 Desired extra isize: 28 Journal inode: 8 First orphan inode: 268015 Default directory hash: half_md4 Directory Hash Seed: cc101517-e617-482b-a883-a72919419c84 Journal backup: inode blocks Journal features: journal_incompat_revoke Journal size: 128M Journal length: 32768 Journal sequence: 0x001d3000 Journal start: 7787 fdisk and parted output per requests: http://pastebin.com/EGVH7Ken

  • Replicate GAE Datastore On A Server LAN in Java

    - by Franz Noel
    There may be instances wherein one Company Client may not have internet connection on their vicinity. Either their Internet Service Provider currently experience a down time or there are some other problems involving the network, but not their LAN. GAE seems to be needing a connection at all times in the internet. I only need GAE Datastore. I'm thinking about a different application. Creating a Java Swing Client, for instance, and connecting to the Office Server via HRD of GAE Datastore. When I tried to check on the solutions for Java, it does not say anything about uploading all data and I do not need the App. I just need the GAE Datastore. In Java GAE, only indexes can be able to be manipulated. So, is there any tricks/ideas that you can use HRD with GAE Datastore on Java with an Internal Office Server combined? This way, it may provide service even during network down times. (Can somebody create me a tag of gae-datastore, please.)

  • Queries regarding Geometry Shaders

    - by maverick9888
    I am dealing with geometry shaders using GL_ARB_geometry_shader4 extension. My code goes like : GLfloat vertices[] = { 0.5,0.25,1.0, 0.5,0.75,1.0, -0.5,0.75,1.0, -0.5,0.25,1.0, 0.6,0.35,1.0, 0.6,0.85,1.0, -0.6,0.85,1.0, -0.6,0.35,1.0 }; glProgramParameteriEXT(psId, GL_GEOMETRY_INPUT_TYPE_EXT, GL_TRIANGLES); glProgramParameteriEXT(psId, GL_GEOMETRY_OUTPUT_TYPE_EXT, GL_TRIANGLE_STRIP); glLinkProgram(psId); glBindAttribLocation(psId,0,"Position"); glEnableVertexAttribArray (0); glVertexAttribPointer(0, 3, GL_FLOAT, 0, 0, vertices); glDrawArrays(GL_TRIANGLE_STRIP,0,4); My vertex shader is : #version 150 in vec3 Position; void main() { gl_Position = vec4(Position,1.0); } Geometry shader is : #version 150 #extension GL_EXT_geometry_shader4 : enable in vec4 pos[3]; void main() { int i; vec4 vertex; gl_Position = pos[0]; EmitVertex(); gl_Position = pos[1]; EmitVertex(); gl_Position = pos[2]; EmitVertex(); gl_Position = pos[0] + vec4(0.3,0.0,0.0,0.0); EmitVertex(); EndPrimitive(); } Nothing is rendered with this code. What exactly should be the mode in glDrawArrays() ? How does the GL_GEOMETRY_OUTPUT_TYPE_EXT parameter will affect glDrawArrays() ? What I expect is 3 vertices will be passed on to Geometry Shader and using those we construct a primitive of size 4 (assuming GL_TRIANGLE_STRIP requires 4 vertices). Can somebody please throw some light on this ?

  • What to do when you're the interviewer and you don't like your job?

    - by emcb
    I'm in a sorta strange predicament, and I could use some advice. When I was interviewing for my current job, the job description I was given seemed pretty darn nice to me. Without going into the details, the job hasn't quite turned out the way it was advertised. The company is great and takes care of its employees, but for someone who cares about the code they write and the work they do, it's a bad environment - effectively, we operate between 0.5 and 1.0 on the Joel test, and due to political issues we're not going to move beyond that any time soon. Bitter? Maybe. OK...so I'm in the market for a new job. But that's not where my dilemma is. The problem that I see coming is that I will be participating in interviewing some candidates for a position on my team, and I'm not sure what to do. I've heard through the grapevine that we have some really solid, promising, fresh-out-of-college prospects coming in to interview, and I honestly dread the thought of somebody having their first experience of engineering in this department. So I'm wondering: what should I do if/when the interviewee asks me "Do you like your job?" (no) "What kind of projects would I be working on?" (mostly static HTML/CSS changes) Anything else that would elicit a negative answer if told truthfully Do I tell the truth, to give the candidate a real picture of the job? What if this scares them away, and what if it gets blamed on me? Do I fib or lie, saying we work on exciting projects with lots of flexibility, like the pitch my boss will give when the reality is quite different? Should I feel any kind of moral responsibility to let a promising young developer know that this isn't the job for them, or should I shut up and be loyal 100% to the company? Any approaches or advice is appreciated. I hope I don't come across as overly dramatic - I honestly struggle with this question.

  • Prevent oversteering catastrophe in racing games

    - by jdm
    When playing GTA III on Android I noticed something that has been annoying me in almost every racing game I've played (maybe except Mario Kart): Driving straight ahead is easy, but curves are really hard. When I switch lanes or pass somebody, the car starts swiveling back and forth, and any attempt to correct it makes it only worse. The only thing I can do is to hit the brakes. I think this is some kind of oversteering. What makes it so irritating is that it never happens to me in real life (thank god :-)), so 90% of the games with vehicles inside feel unreal to me (despite probably having really good physics engines). I've talked to a couple of people about this, and it seems either you 'get' racing games, or you don't. With a lot of practice, I did manage to get semi-good at some games (e.g. from the Need for Speed series), by driving very cautiously, braking a lot (and usually getting a cramp in my fingers). What can you do as a game developer to prevent the oversteering resonance catastrophe, and make driving feel right? (For a casual racing game, that doesn't strive for 100% realistic physics) I also wonder what games like Super Mario Kart exactly do differently so that they don't have so much oversteering? I guess one problem is that if you play with a keyboard or a touchscreen (but not wheels and pedals), you only have digital input: gas pressed or not, steering left/right or not, and it's much harder to steer appropriately for a given speed. The other thing is that you probably don't have a good sense of speed, and drive much faster than you would (safely) in reality. From the top of my head, one solution might be to vary the steering response with speed.
