• Can I run Linux on the HP Mini from Verizon Wireless, with a built-in 3G modem, and connect using the built in modem?

  - by Parker

  I apologize if my question made little sense, I am very tired at the moment. Anyway, Recently I purchases the HP Mini from Verizon Wireless. It runs on the Intel Atom processor and came with Windows 7 Starter Edition, which is quite possibly the worst and most restrictive OS I have ever used. I plan on installing CRUX, after doing a little research on minimal, free, Linux operating systems, as I am working on web programming using Python, among other things. My only worry is that, because my HP Mini uses a built in wireless card (and I have no wifi connection, only a 3G connection) that has a "mobile access" connection to Verizon wireless, I am not sure if after installing CRUX that I would still be able to connect using this option. I have never used Linux before, and am hoping this will work. So if anybody has experience with this...please answer, can I connect to vzw 3G with linux, using an internal mobile access card...

• Use a media player in Linux just to play files from an iPod device (no sync, no manage, just play)?

  - by Somebody still uses you MS-DOS

  I have an ipod classic 160gb, that I sync with my machine at home. I use Linux at work, and want to just plug my ipod and just listen to the tracks, with all the playlists and such. I don't want to sync nothing, I just want to listen to the tracks as if I was using the ipod itself. Why? Because this way I can use the usb port. So, I don't want to manage my ipod in Linux, I just want to listen to the tracks on it in Linux, like it was a local library but it's instead in my ipod. (I've tried gtkpod, it works to show my files, but I can't play, shuffle, etc. It would be interesting to have a complete audio software to handle everything like it was a local library)

• Is (Ubuntu) Linux file copying algorithm better than Windows 7?

  - by Sarath

  Windows Copying is a real mess ever since Windows Vista. Even Microsoft claims they've improved the performance, from a user perspective, it's not quite visible. Even with single file the copying window appears too much time for 'Calculating' and then finishing the copy(Even after 100% completion some times the dialog remains active). At the same time, I was backing up some files in Ubuntu Linux. I felt it's really fast. Might be a feeling caused by faster UI updates. I read an informative post from Jeff Atwood few years back on Windows File Copying. but what my specific questions are Is (Ubuntu) Linux file performance is better than Windows-7? Are both algorithms, Windows and Linux is making use of multiple threads and pipelining mechanism to improve the speed? If yes, which one is better?

• Moving from windows to linux : Understanding - X Window System, X Server, Xorg, Xfree86.

  - by claws

  Hello, I'm a windows developer(Win32api) moving from Windows to Linux. While installing linux there are lot of things to know about X11, X Window System, X Server, Xorg, Xfree86 and what not. How come we aren't aware of such things in windows? Wiki article on these scares me. Can any one explain these things? How they work? Why is it so complicated in linux & not in windows? Any good references are also appreciated. PS: I love to know internals, don't hesitate to go into depth.

• Is there a filesystem that is "friendly" to both windows and Linux?

  - by Somebody still uses you MS-DOS

  I'm planning to install Ubuntu 10.04 with Windows 7. (I'm new to Linux, have to use at work so I'm planning to install it at home to learn more) I plan to use a partition to my Windows system files (C:), a partition for my personal files that already exists (D:) and a new partition for Linux. What I want is to have a partition for my personal files that works across these systems - so, if I start with Windows or Linux, there's the same "Videos", "Pictures", "Projects" folders. Is it possible? Is there a hd filesystem capable of having writes from both systems without too much risk of corrupting or something?

I've read some horror stories of corruption, and would like to know from a sysadmin POV all the risks involved in such scenario.

• How can one create a bootable linux usb key that works on Mac (Intel 64 bit CPU) hardware ?

  - by user3621

  Hi, I'm trying to create a bootable usb key with linux (debian) and that can be booted on Macintel hardware. I have read that MAC's EFI can only boot GPT GUID formatted disks. I'm desperately trying to find a good tutorial which explains how to create such a key. Here what I have done so far: create a GUID partition on te key using linux GNU parted create a HFS+ or ext3 partition on the key, with the boot flag on install a linux .iso with unetbootin While all steps were successfull and in some cases I could even boot on a PC, the step of booting on Macintel software failed (on a macbook). I need to precise that I holded the "alt" key while booting the mac and the only visible bootable disk was the hard disk. Thanks for any advice. PS: I have tried with rEFIt as well. In one case I had a "windows" icon but it then failed to boot with a message like "no system found"

• Books or other materials to overcome Linux learning curve?

  - by Marek Osvald

  I was born in 1989 and am an active Windows user since 1993. I've always struggled with Linux, not being able to configure the system the way I would like, snooping through blogs and forums for answers, never actually overcame the barrier. The books I've seen and read are either completely command line oriented (and don't get me wrong it's awesome to know this stuff when you're working on a server for example) but seems rather impractical to me on a desktop computer that's partially my development environment. The other kind are user manual describing step-by-step the controls of simplest applications like the Calculator, totally useless to me. What would you recommend for a programmer who needs to learn how to work with Linux but already knows the basics? What materials did you use to learn how to start with Linux?

• how to manage a multi user server on linux?

  - by user1175942

  I'm working on a university project, where I have Tomcat as a web server, and I want to create a multi user environment on top of linux, so every user that logs into my website has his own credentials, and he can access only his own data (files and folders...). The main issue is that the purpose of the website is executing code on the server-side, so I must have a good (reasonable) protection against malicious code. (a user destroying his own user is fine by me) I thought that defining a linux-user for every website-user is the best solution - it isolates each user from the other, and I can define each one's permissions. Can I create users in linux using shell commands? Can I configure max quota/memory/cpu for a user? Anyone has another idea for managing that kind of multi-user environment?

• How do I install PyYAML into local install of Python?

  - by Daryl Spitzer

  I've installed Python 2.6.4 into (a subdirectory in) my home directory on a Linux machine with Python 2.3.4 pre-installed, because I need to run some code that I've decided would require too much work to make it run on 2.3.4. (I'm not on the sudoers list for that machine.) I was hoping I could run ~/Python-2.6.4/python setup.py install (from the PyYAML directory in my home directory, where I untarred the PyYAML sources) and it would be smart enough to install it into my local Python 2.6.4 install. But it's not. (See the P.S.) Is it possible to install PyYAML into my local Python install, so that "import yaml" will work when I invoke that Python? If so, how do I do that? P.S. Here's the output when I ran ~/Python-2.6.4/python setup.py install: running install running build running build_py creating build/lib.linux-ppc64-2.6 creating build/lib.linux-ppc64-2.6/yaml copying lib/yaml/composer.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/nodes.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/dumper.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/resolver.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/events.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/emitter.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/error.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/loader.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/cyaml.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/scanner.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/__init__.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/serializer.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/reader.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/representer.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/constructor.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/tokens.py -> build/lib.linux-ppc64-2.6/yaml copying lib/yaml/parser.py -> build/lib.linux-ppc64-2.6/yaml running build_ext creating build/temp.linux-ppc64-2.6 checking if libyaml is compilable gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I/home/dspitzer/Python-2.6.4/Include -I/home/dspitzer/Python-2.6.4 -c build/temp.linux-ppc64-2.6/check_libyaml.c -o build/temp.linux-ppc64-2.6/check_libyaml.o build/temp.linux-ppc64-2.6/check_libyaml.c:2:18: yaml.h: No such file or directory build/temp.linux-ppc64-2.6/check_libyaml.c: In function `main': build/temp.linux-ppc64-2.6/check_libyaml.c:5: error: `yaml_parser_t' undeclared (first use in this function) build/temp.linux-ppc64-2.6/check_libyaml.c:5: error: (Each undeclared identifier is reported only once build/temp.linux-ppc64-2.6/check_libyaml.c:5: error: for each function it appears in.) build/temp.linux-ppc64-2.6/check_libyaml.c:5: error: syntax error before "parser" build/temp.linux-ppc64-2.6/check_libyaml.c:6: error: `yaml_emitter_t' undeclared (first use in this function) build/temp.linux-ppc64-2.6/check_libyaml.c:8: warning: implicit declaration of function `yaml_parser_initialize' build/temp.linux-ppc64-2.6/check_libyaml.c:8: error: `parser' undeclared (first use in this function) build/temp.linux-ppc64-2.6/check_libyaml.c:9: warning: implicit declaration of function `yaml_parser_delete' build/temp.linux-ppc64-2.6/check_libyaml.c:11: warning: implicit declaration of function `yaml_emitter_initialize' build/temp.linux-ppc64-2.6/check_libyaml.c:11: error: `emitter' undeclared (first use in this function) build/temp.linux-ppc64-2.6/check_libyaml.c:12: warning: implicit declaration of function `yaml_emitter_delete' libyaml is not found or a compiler error: forcing --without-libyaml (if libyaml is installed correctly, you may need to specify the option --include-dirs or uncomment and modify the parameter include_dirs in setup.cfg) running install_lib creating /usr/local/lib/python2.6 error: could not create '/usr/local/lib/python2.6': Permission denied

• Facing issues in setting up VPN connection(IKEv1) using iphone (Defult Cisco VPN client) and Strongswan 4.5.0 server

  - by Kushagra Bhatnagar

  I am facing issues in setting up VPN connection(IKEv1) using iPhone (Defult Cisco VPN client) and Strongswan 4.5.0 server. The Strongswan server is running on Ubuntu Linux, which is connected to some wifi hotspot. This is the guide which was used. I generated CA, server and client certificate, with the only difference mentioned below. “While generating server certificate, as per link CN=vpn.strongswan.org instead of this I changed CN name to CN=192.168.43.212.” Once certificates are generated, following (clientCert.p12 and caCert.pem) are sent to mobile via mail and installed on iphone. After installation I notice that certificates are considered as trusted also. Below are the ip addresses assigned to various interfaces Linux server wlan0 interface ip where server is running: 192.168.43.212 Iphone eth0 interface ip address: 192.168.43.72. iphone is also attached with the same wifi hotspot. Below is the snapshot of client configurations. Description Strong swan Server 192.168.43.212 Account ipsecvpn Password ***** Use certificate ON Certificate client The above username and password are in sync with the ipsec.secrets file. I am using the following ipsec.conf configuration: # basic configuration config setup plutodebug=all # crlcheckinterval=600 # strictcrlpolicy=yes # cachecrls=yes nat_traversal=yes # charonstart=yes plutostart=yes # Add connections here. # Sample VPN connections conn ios1 keyexchange=ikev1 authby=xauthrsasig xauth=server left=%defaultroute leftsubnet=0.0.0.0/0 leftfirewall=yes leftcert=serverCert.pem right=192.168.43.72 rightsubnet=10.0.0.0/24 rightsourceip=10.0.0.2 rightcert=clientCert.pem pfs=no auto=add With the above configurations when I enable VPN on iphone, it says Could not able to verify server certificate. I ran Wireshark on a Linux server and observe that initially some ISAKMP message exchanges happens between client and server, which are successful but before authorization, client is sending some informational message and soon after this client is showing error as popup Could not able to verify server certificate. Capture logs on Strongswan server and in server logs below errors are observed: From auth.log Apr 25 20:16:08 Linux pluto[4025]: | ISAKMP version: ISAKMP Version 1.0 Apr 25 20:16:08 Linux pluto[4025]: | exchange type: ISAKMP_XCHG_INFO Apr 25 20:16:08 Linux pluto[4025]: | flags: ISAKMP_FLAG_ENCRYPTION Apr 25 20:16:08 Linux pluto[4025]: | message ID: 9d 1a ea 4d Apr 25 20:16:08 Linux pluto[4025]: | length: 76 Apr 25 20:16:08 Linux pluto[4025]: | ICOOKIE: f6 b7 06 b2 b1 84 5b 93 Apr 25 20:16:08 Linux pluto[4025]: | RCOOKIE: 86 92 a0 c2 a6 2f ac be Apr 25 20:16:08 Linux pluto[4025]: | peer: c0 a8 2b 48 Apr 25 20:16:08 Linux pluto[4025]: | state hash entry 8 Apr 25 20:16:08 Linux pluto[4025]: | state object not found Apr 25 20:16:08 Linux pluto[4025]: **packet from 192.168.43.72:500: Informational Exchange is for an unknown (expired?)

• 2.5D game development

  - by ne5tebiu

  2.5D ("two-and-a-half-dimensional"), 3/4 perspective and pseudo-3D are terms used to describe either: graphical projections and techniques which cause a series of images or scenes to fake or appear to be three-dimensional (3D) when in fact they are not, or gameplay in an otherwise three-dimensional video game that is restricted to a two-dimensional plane. (Information taken from Wikipedia.org) I have a question based on 2.5D game development. As stated before, 2.5D uses graphical projections and techniques to make fake 3d or a gameplay restricted to a two-dimensional plane. A good example is a TQ Digital made game: Zero Online (screenshot) the whole map is made of 2d images and only NPCs and players are 3d. The maps were drawn manually by hand without any 3d software rendering. As I'm playing the game I feel like I'm going from a lower part of the map (ground) to a higher one (some metal platform) and it feels like I'm moving in 3 dimensions. But when I look closely, I see that the player size didn't change and the shadow too but I'm still feeling like I'm somehow higher then before (I had rendered a simple map myself that I made in 3dmax but it didn't quite give the result I wanted). How to accomplish such an effect?

• How to penetrate the QA industry after layoffs, next steps...

  - by Erik

  Briefly, my background is in manual black box testing of websites and applications within the Agile/waterfall context. Over the past four years I was a member of two web development firms' small QA teams dedicated to testing the deployment of websites for national/international non profits, governmental organizations, and for profit business, to name a few: -Brookings Institution -Senate -Tyco Electronics -Blue Cross/Blue Shield -National Geographic -Discover Channel I have a very strong understanding of the: -SDLC -STLC of bugs and website deployment/development -Use Case & Test Case development In March of this year, my last firm downsized and lost my job as a QA tester. I have been networking and doing a very detailed job search, but have had a very difficult time getting my next job within the QA industry, even with my background as a manual black box QA tester in the website development context. My direct question to all of you: What are some ways I can be more competitive and get hired? Options that could get me competitive: Should I go back to school and learn some more 'hard' skills in website development and client side technologies, e.g.: -HTML -CSS -JavaScript Learn programming: -PHP -C# -Ruby -SQL -Python -Perl -?? Get Certified as a QA Tester, there are a countless numbers of programs to become a Certified Tester. Most, if not all jobs, being advertised now require Automated Testing experience, in: -QTP -Loadrunner -Selenium -ETC. Should I learn, Automated testing skills, via a paid course, or teach myself? --Learn scripting languages to understand the automated testing process better? Become a Certified "Project Management Professional" (PMP) to prove to hiring managers that I 'get' the project development life cycle? At the end of the day I need to be competitive and get hired as a QA tester and want to build upon my skills within the QA web development field. How should I do this, without reinventing the wheel? Any help in this regard would be fabulous. Thanks! .erik

• Welcome to the Weblog on Oracle ADF Mobile!

  - by joe.huang

  Welcome to ADF Mobile team's weblog.  My name is Joe Huang - I am the product manager for ADF Mobile.  Oracle ADF Mobile is a part of Oracle's Application Development Framework (ADF) that support the development of enterprise/business applications that run on mobile devices.  The development tool for this framework is of course Oracle JDeveloper.  As some of you may know, we currently support the development of mobile browser-based application - this part of product is called ADF Mobile Browser.  Additionally, we are close to release a technology preview of ADF Mobile Client, which supports development of on-device, disconnect capable mobile applications.  What's truly unique about ADF Mobile development process is that it's a very visual and declarative experience, while still allow power Java developers to completely extend the framework to their liking.  The framework also provides a rich set of services needed by an enterprise-grade mobile application - these services would literally take years to implement if they are to be built from the ground up.  However, by using JDeveloper and ADF Mobile, you get the entire framework at your service!In the coming entries, the ADF Mobile product development team will publish any news, best practices, our observation on mobile technology trends, or just our experiences in playing with "gadgets".  Be sure to check back on this page!Sincerely,Joe HuangOracle

• Degraded RAID5 and no md superblock on one of remaining drive

  - by ark1214

  This is actually on a QNAP TS-509 NAS. The RAID is basically a Linux RAID. The NAS was configured with RAID 5 with 5 drives (/md0 with /dev/sd[abcde]3). At some point, /dev/sde failed and drive was replaced. While rebuilding (and not completed), the NAS rebooted itself and /dev/sdc dropped out of the array. Now the array can't start because essentially 2 drives have dropped out. I disconnected /dev/sde and hoped that /md0 can resume in degraded mode, but no luck.. Further investigation shows that /dev/sdc3 has no md superblock. The data should be good since the array was unable to assemble after /dev/sdc dropped off. All the searches I done showed how to reassemble the array assuming 1 bad drive. But I think I just need to restore the superblock on /dev/sdc3 and that should bring the array up to a degraded mode which will allow me to backup data and then proceed with rebuilding with adding /dev/sde. Any help would be greatly appreciated. mdstat does not show /dev/md0 # cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] md5 : active raid1 sdd2[2](S) sdc2[3](S) sdb2[1] sda2[0] 530048 blocks [2/2] [UU] md13 : active raid1 sdd4[3] sdc4[2] sdb4[1] sda4[0] 458880 blocks [5/4] [UUUU_] bitmap: 40/57 pages [160KB], 4KB chunk md9 : active raid1 sdd1[3] sdc1[2] sdb1[1] sda1[0] 530048 blocks [5/4] [UUUU_] bitmap: 33/65 pages [132KB], 4KB chunk mdadm show /dev/md0 is still there # mdadm --examine --scan ARRAY /dev/md9 level=raid1 num-devices=5 UUID=271bf0f7:faf1f2c2:967631a4:3c0fa888 ARRAY /dev/md5 level=raid1 num-devices=2 UUID=0d75de26:0759d153:5524b8ea:86a3ee0d spares=2 ARRAY /dev/md0 level=raid5 num-devices=5 UUID=ce3e369b:4ff9ddd2:3639798a:e3889841 ARRAY /dev/md13 level=raid1 num-devices=5 UUID=7384c159:ea48a152:a1cdc8f2:c8d79a9c With /dev/sde removed, here is the mdadm examine output showing sdc3 has no md superblock # mdadm --examine /dev/sda3 /dev/sda3: Magic : a92b4efc Version : 00.90.00 UUID : ce3e369b:4ff9ddd2:3639798a:e3889841 Creation Time : Sat Dec 8 15:01:19 2012 Raid Level : raid5 Used Dev Size : 1463569600 (1395.77 GiB 1498.70 GB) Array Size : 5854278400 (5583.08 GiB 5994.78 GB) Raid Devices : 5 Total Devices : 4 Preferred Minor : 0 Update Time : Sat Dec 8 15:06:17 2012 State : active Active Devices : 4 Working Devices : 4 Failed Devices : 1 Spare Devices : 0 Checksum : d9e9ff0e - correct Events : 0.394 Layout : left-symmetric Chunk Size : 64K Number Major Minor RaidDevice State this 0 8 3 0 active sync /dev/sda3 0 0 8 3 0 active sync /dev/sda3 1 1 8 19 1 active sync /dev/sdb3 2 2 8 35 2 active sync /dev/sdc3 3 3 8 51 3 active sync /dev/sdd3 4 4 0 0 4 faulty removed [~] # mdadm --examine /dev/sdb3 /dev/sdb3: Magic : a92b4efc Version : 00.90.00 UUID : ce3e369b:4ff9ddd2:3639798a:e3889841 Creation Time : Sat Dec 8 15:01:19 2012 Raid Level : raid5 Used Dev Size : 1463569600 (1395.77 GiB 1498.70 GB) Array Size : 5854278400 (5583.08 GiB 5994.78 GB) Raid Devices : 5 Total Devices : 4 Preferred Minor : 0 Update Time : Sat Dec 8 15:06:17 2012 State : active Active Devices : 4 Working Devices : 4 Failed Devices : 1 Spare Devices : 0 Checksum : d9e9ff20 - correct Events : 0.394 Layout : left-symmetric Chunk Size : 64K Number Major Minor RaidDevice State this 1 8 19 1 active sync /dev/sdb3 0 0 8 3 0 active sync /dev/sda3 1 1 8 19 1 active sync /dev/sdb3 2 2 8 35 2 active sync /dev/sdc3 3 3 8 51 3 active sync /dev/sdd3 4 4 0 0 4 faulty removed [~] # mdadm --examine /dev/sdc3 mdadm: No md superblock detected on /dev/sdc3.

• game multiplayer service development

  - by nomad

  I'm currently working on a multiplayer game. I've looked at a number of multiplayer services(player.io, playphone, gamespy, and others) but nothing really hits the mark. They are missing features, lack platform support or cost too much. What I'm looking for is a simple poor man's version of steam or xbox live. Not the game marketplace side of those two but the multiplayer services. User accounts, profiles, presence info, friends, game stats, invites, on/offline messaging. Basically I'm looking for a unified multiplayer platform for all my games across devices. Since I can't find what I'm planning to roll my own piece by piece. I plan to save on server resources by making most of the communication p2p. Things like game data and voice chat can be handled between peers and the server keeps track of user presence and only send updates when needed or requested. I know this runs the risk of cheating but that isn't a concern right now. I plan to run this on a Amazon ec2 micro server for development then move to a small to large instance when finished. I figure user accounts would be the simplest to start with. Users can create accounts online or using in game dialog, login/out, change profile info. The user can access this info online or in game. I will need user authentication and secure communication between server and client. I figure all info will be stored in a database but I dont know how it can be stored securely and accessed from webserver and game services. I would appreciate and links to tutorials, info or advice anyone could provide to get me started. Any programming language is fine but I plan to use c# on the server and c/c++ on devices. I would like to get started right away but I'm in no hurry to get it finished just yet. If you know of a service that already fits my requirements please let me know.

• In-House Generated Certificates Supported for Signing E-Business Suite JAR Files

  - by Elke Phelps (Oracle Development)

  The E-Business Suite uses Java Archive (JAR) files to deliver certain types of E-Business Suite content desktop clients.  Previously we announced the support of securing JAR files with 3072-bit certificates signed by a third-party Certificate Authority (CA).  We now support securing JAR files with in-house generated certificates.  The new steps to use an in-house Certificate Authority for securing JAR files are provided in: Enhanced Signing of Oracle E-Business Suite JAR Files (Note 1207184.1) This enhancement is great news for those of you familiar with the warning that is triggered when using a self-signed certificate.  As a result of supporting self-signed certificates, the following warning can be avoided: Oracle E-Business Suite Release 12 Certified Platforms Linux x86 (Oracle Linux 4, 5) Linux x86 (RHEL 3, 4, 5) Linux x86 (SLES 9, 10) Linux x86-64 (Oracle Linux 4, 5) Linux x86-64 (RHEL 4, 5) Linux x86-64 (SLES 9, 10)  Oracle Solaris on SPARC (64-bit) (8, 9, 10) IBM AIX on Power Systems (64-bit) (5.3, 6.1) IBM Linux on System z** (RHEL 5, SLES 9, SLES 10) HP-UX Itanium (11.23, 11.31) HP-UX PA-RISC (64-bit) (11.11, 11.23, 11.31) Microsoft Windows Server (32-bit) (2003, 2008 for EBS 12.1 only) Oracle E-Business Suite Release 11i Certified Platforms Linux x86 (Oracle Enterprise Linux 4, 5) Linux x86 (RHEL 3, 4, 5) Linux x86 (SLES 8, 9, 10) Linux x86 (Asianux 1.0) Oracle Solaris on SPARC (64-bit) (8, 9, 10) IBM AIX on Power Systems (64-bit) (5.3, 6.1) HP-UX PA-RISC (64-bit) (11.11, 11.23, 11.31) HP Tru64 (5.1b) Microsoft Windows Server (32-bit) (2000, 2003) References Enhanced Signing of Oracle E-Business Suite JAR Files (Note 1207184.1) Related Articles Two New Options for Signing E-Business Suite JAR Files Now Available What Are the Minimum Desktop Requirements for EBS?

• Version control for game development - issues and solutions?

  - by Cyclops

  There are a lot of Version Control systems available, including open-source ones such as Subversion, Git, and Mercurial, plus commercial ones such as Perforce. How well do they support the process of game-development? What are the issues using VCS, with regard to non-text files (binary files), large projects, etc? What are solutions to these problems, if any? For organization of Answers, let's try on a per-package basis. Update each package/Answer with your results. Also, please list some brief details in your answer, about whether your VCS is free or commercial, distributed versus centralized, etc. Update: Found a nice article comparing two of the VCS below - apparently, Git is MacGyver and Mercurial is Bond. Well, I'm glad that's settled... And the author has a nice quote at the end: It’s OK to proselytize to those who have not switched to a distributed VCS yet, but trying to convert a Git user to Mercurial (or vice-versa) is a waste of everyone’s time and energy. Especially since Git and Mercurial's real enemy is Subversion. Dang, it's a code-eat-code world out there in FOSS-land...

• How to go from mainstream to indie development?

  - by Salano Software

  I'm currently working as a game programmer for a AAA-level developer and publisher - which falls into the 'nice problem to have' category, I know, except that I'm growing more and more disenchanted with the direction of both the company and the AAA portion of the industry as a whole. I don't see any games on the studio's calendar for the next several years that I'm actually interested in working on; it looks like a continuing parade of sequels, license extensions and largely-derivative work. Which isn't to say that there won't be interesting things to do on those projects; but more and more I find myself wanting to do something fundamentally different. It seems like the market's never been better for smaller-scale projects, and I'd love to jump into that (and I've done small demos for Android and have started digging into iOS), but I obviously can't put anything out while I'm working for the company, and I'm concerned that I shouldn't even do substantial development in my spare time on anything I'd eventually like to release on my own. At the same time, I'm leery of leaving the job I've got for hopefully-obvious reasons, especially without a specific plan in place. Has anyone out there got experience with 'going indie' out of a mainstream job, and does anyone have specific suggestions as to what the best approach is and what I should specifically be thinking about or be careful of?

• Nvidia drivers don't work with mainline kernel

  - by dutchie

  I want to try some of the new features in the btrfs filesystem, and to do that I need to use a newer kernel than is included in Ubuntu 12.04. To do that, I have installed linux-headers-3.4.0-030400_3.4.0-030400.201205210521_all.deb, linux-headers-3.4.0-030400-generic_3.4.0-030400.201205210521_amd64.deb, and linux-image-3.4.0-030400-generic_3.4.0-030400.201205210521_amd64.deb from the mainline kernel download here. However, on rebooting into the 3.4 kernel, my desktop is stuck at a very low resolution and I cannot increase it to the full. This did happen when I first installed, but a simple install of the nvidia-current package got everything working nicely with my GTX570 card. There were appear to be some DKMS errors when I installed the kernel, and they indicated I should look at /var/lib/dkms/nvidia-current/295.40/build/make.log: josh@sirius:~/Downloads$ sudo dpkg -i linux-*.deb Selecting previously unselected package linux-headers-3.4.0-030400.

• Real life example of an agile game development process outputs

  - by Ken

  I'm trying to learn about applying agile methodologies to game development. But seems to be impossible to find real life examples. There seems to be plenty of material discussing how 'in principle' agile is applied to a game. But that is NOT what I am looking for. I have the Keith book. What I AMlooking for are real EXAMPLES of things like; Initial user stories Final user stories (complete, covering the entire game requirements) Acceptance criteria Task list Sprint backlogs (before and after each sprint) The agile books seem to have some limited examples, many of which seem contrived or limited. In this era of open source software, there must be a publicly available documented example of the process applied to a real game. I am asking specifically about games because they are so different from normal applications. Regular applications are built to all users to complete specific tasks in order to get stuff done(book a room, print a report etc). People play games for much less tangible reasons, so I think the process is significantly different. [it doesn't have to be scrum, it could be any process, just needs to be a real life example game and be reasonably complete]

• Any good resources on setting up an ubuntu virtual machine for web development?

  - by Relequestual

  I'm currently on my placement year at uni with 4 months left. Before working at my current place, I have not used a nix environment for web development and have used WAMP. Over the past year I have found some very interesting new tech that requires a bit more than my shared hosting even to play with (eg node.js, RoR 3). At work we use a Virtual Machine for development, but that's all been set up and configured to match the live servers, and is managed with a Puppet server. Are there any really good resources for setting up and configuring an Ubuntu VM as a web server? Work currently uses Ubuntu so I would assume this is a good OS to use. I do of course know how to use google, but the noise ratio is just too big, so thought I'd ask here, as I know many of you will have a ton of bookmarks. Cheers.

• Mac OSX Programming for long time Linux geek

  - by DarenW

  I've written software on Linux since 1995 but must get up to speed with app development on the Mac. I have no experience on that platform. Obviously I should get my hands on some appropriate hardware. What are good books, tutorial websites, and other resources for experienced devs getting started on Mac? Not just APIs and app internals, but also including how does one install an app, debug it, etc?
