• Photo managing software that supports network drives?

  - by musicfreak

  My dad is a photographer in his free time, and he's been using Lightroom to manage his photos. However, recently, we put all of our photos on a NAS drive to allow us to access them from any computer at any time. The problem with this is that Lightroom cannot load catalogs from network drives. We need support for network drives because we'd like to be able to browse the photos from any computer, and for any computer to be able to add photos to the collection. Right now we're just syncing the Lightroom catalog file between us, but the extra step is a pain, and doing it manually makes it error-prone. Is there any software (free or commercial) that has proper support for network drives? The only real feature I need is to be able to sort photos by date and by some sort of tags. I don't need any editing features like those found in Lightroom; my dad is comfortable using Photoshop to edit photos. Also, if there is another solution to this that I haven't thought of, feel free to share.

• Recommended programming language for linux server management and web ui integration.

  - by Brendan Martens

  I am interested in making an in house web ui to ease some of the management tasks I face with administrating many servers; think Canonical's Landscape. This means doing things like, applying package updates simultaneously across servers, perhaps installing a custom .deb (I use ubuntu/debian.) Reviewing server logs, executing custom scripts, viewing status information for all my servers. I hope to be able to reuse existing command line tools instead of rewriting the exact same operations in a different language myself. I really want to develop something that allows me to continue managing on the ssh level but offers the power of a web interface for easily applying the same infrastructure wide changes. They should not be mutually exclusive. What are some recommended programming languages to use for doing this kind of development and tying it into a web ui? Why do you recommend the language(s) you do? I am not an experienced programmer, but view this as an opportunity to scratch some of my own itches as well as become a better programmer. I do not care specifically if one language is harder than another, but am more interested in picking the best tools for the job from the beginning. Feel free to recommend any existing projects except Landscape (not free,) Ebox (not entirely free, and more than I am looking for,) and webmin (I don't like it, feels clunky and does not integrate well with the "debian way" of maintaining a server, imo.) Thanks for any ideas!

• High fan speed with no reason

  - by Klaus

  For a few weeks, the fans of my Lenovo B590 laptop, running on Xubuntu 14, turn to high speed a few minutes after it is turned on. The fans won't speed down until I turn the computer off. This is quite strange, since This didn't happen before The temperatures are quite low (are they ?) $sensors Adapter: Virtual device temp1: +36.0°C (crit = +88.0°C) temp2: +30.0°C (crit = +126.0°C) coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +37.0°C (high = +72.0°C, crit = +90.0°C) Core 0: +34.0°C (high = +72.0°C, crit = +90.0°C) Core 1: +31.0°C (high = +72.0°C, crit = +90.0°C) thinkpad-isa-0000 Adapter: ISA adapter fan1: 0 RPM pkg-temp-0-virtual-0 Adapter: Virtual device temp1: +37.0°C $sudo hddtemp /dev/sda /dev/sda: ST500LT012-9WS142: 33°C The computer is under low load: top - 08:30:15 up 16 min, 2 users, load average: 0.28, 0.23, 0.23 Tasks: 197 total, 1 running, 196 sleeping, 0 stopped, 0 zombie %Cpu(s): 0.8 us, 0.5 sy, 0.0 ni, 98.7 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st KiB Mem: 3607944 total, 1973956 used, 1633988 free, 99660 buffers KiB Swap: 3744764 total, 0 used, 3744764 free. 789936 cached Mem The BIOS is up to date (and there are no fan settings in it) The fan is clean and dust-free Why would the BIOS turn the fans to high speed where there seem to be no reason for that ? It seems that we cannot control the fan manually with this model, so I guess the only solution is to understand why this happens.

• What tool can I use to definitely kill a process on Windows?

  - by Moak

  Can anyone recommend an application (preferably usb-portable that doesn't require setup) That really kills a process immediately in windows XP? I ask this because often when I need to use the XP task manager it seems to want to go about it "the polite way" and sometimes crashed programs don't quit or take a minute to shut down. I need a real stone cold killer, not a pushover-could-you-please-quit-now-no?-ok-sorry-program Edit I'm sorry if it wasn't clear previously but I did mean the situation when even the "End process" command in Process tab of the task manager doesn't kill a program, however one of the answers did point me to the "End Process Tree" command which I've never noticed (when right clicking on the process)

• Imac g5 with no OS nor CD drive

  - by sinekonata

  What I want: Ubuntu on a g5 Imac. What I have: An empty PC (Intel g5 17" Imac) with broken CD drive. Its model is A1173. This PC with Ubuntu 12.04 and an old Vista partition. a usb flash drive. Problems: No CD means the only boot Drive I could use is USB. There are no BIOS on Macs so I can't set boot settings or even see if it detects my USB drive. When I start the machine and press ALT the first and only thing I see is an old corrupted winXP partition and not a single option or additional information. So assuming blindly that the Mac hardware/firmware works normally, I don't have any Mac OS to use any of the tools that I found on different tutorials for building a bootable .img drive for macs. I can't find much software on Linux/Windows to substitute to those tools, for example among others converting an .iso file (win/linux) to .img (mac I guess). Which makes me think that the scenario where someone like me has Mac hardware but no Mac OS is extremely rare. So other than finding someone that has a Mac I have no solution. So I ask what would you do? the only thing is it should not involve any money (I know mac soft is rarely free) which also excludes getting any MacOS unless I can use a free macos.img for VM or restore the original Mac for free. Thank you

• Recover data from quick formatted DVD-R

  - by Andrii Kalytiiuk

  I need to recover data from quick-formatted DVD-R. Please advise a free of charge option (cheap commercial tools will be ok either). Disk was partially recorded with Windows built in disk recorder and recording most likely was not complete. Afterwards I have inserted partially recorded DVD again and on Windows recorder's message box 'How to use this disk?' selected - 'use for CD/DVD player' and data was completely lost - as new recording session was started. Files of photos were recorded on disk. What I have tried so far: DiskInternals CD-DVD recovery - sees 5 jpg files but can't show preview. Tool is commercial - trial version does not allow to recover files. CDCheck - doesn't see any files and reports errors at attempt to scand DVD CD Recovery Toolbox Free - does not even recognize DVD drive ISO Buster - recognizes two files - one MP3 file for 99% of recorded size and one ARC file for about 100 KB MiniTool Power Data Recovery - Free Edition - does not see any files on DVD Stellar Phoenix CD DVD Data Recovery - does not see any files BinaryBiz Virtual Lab - sees DVD disk but needs license to browse content Please advise how is it possible to recover files from DVD.

• Why is my cron daemon is being killed every few minutes?

  - by user113215

  As of about a week ago, my cron daemon refuses to stay running. I'm using Debian 6 x64 on an OpenVZ virtual machine. Running something like pgrep cron shows that the daemon isn't running. I start the service with service cron start or /etc/init.d/cron start and it launches, but it disappears from the running process list after a few minutes (varying anywhere between 1 - 30 minutes before the process is killed again). Using strace -f service cron start, I can see that the process is being killed for some reason: nanosleep({60, 0}, <unfinished ...> +++ killed by SIGKILL +++ There's nothing relevant in /var/log/syslog, /var/log/messages, /var/log/auth.log, or /var/log/kern.log to explain why the the process is dying. The system has at least 800 MB of free memory, and cat /proc/loadavg returns 0.22 0.13 0.04 so resources shouldn't be the issue. With cron running, free -m reports: total used free shared buffers cached Mem: 1024 211 812 0 0 0 -/+ buffers/cache: 211 812 Swap: 0 0 0 I also tried removing and reinstalling the cron package using apt-get. Update: I initially thought the problem was a resource issues. I erased my entire VPS and started from a fresh Debian image. There is now nothing else running on the system, but even from a clean install my cron daemon is still being killed at random. What else should I check? How do I find out what's killing my crond?

• Fresh install CentOS 6.4 64b with directadmin slowly consumes all memory and crashes

  - by Coen Ponsen

  Dear server fault community, This is my first question on server fault, i'm new to server (mis)configuration so please forgive me for asking something stupid :) I'm running Directadmin on a CentOS 6.4 64b with 4GB memory and over 10000Gh virtual machine. I migrated my websites because my former vps couldn't keep up anymore. Only half of the websites from this 1GB machine were migrated jet. So the migration is still in progress and already my server crashes every day. The server performance up until that moment is perfect. The directadmin log files show nothing out of the ordinary. Yesterday only the mysql server crashed but it also crashed the entire machine before. The memory usage in DA seems to be normal: directadmin directadmin (pid 3923 22158 22159 22160 22161 22162 )8.75 MB dovecot dovecot (pid 3851 ) 47.8 MB exim exim (pid 1350 ) 1.29 MB httpd (pid 21525 21528 21529 21530 21531 21532 21546 21571 21742 21743 21744 )490.4 MB mysqld mysqld (pid 1299 ) 287.8 MB named named (pid 3807 ) 16.3 MB proftpd proftpd (pid 1481 ) 1.91 MB sshd sshd (pid 1173 21494 ) 5.16 MB Restarting services immediately frees up memory, but slowly over time the memory usage increases(about 24 hours to crash). The commands: # sync # echo 3 > /proc/sys/vm/drop_caches Will free al memory correct. I could just create a cronjob but it seems the wrong way around to me. I can't seem to pinpoint the cause. Any advices, references or tips are highly appreciated! Greetings, Coen edit: free -m : after drop_caches: total used free shared buffers cached Mem: 3830 735 3095 0 0 21 -/+ buffers/cache: 712 3117 Swap: 991 0 991 I'll post another one this evening.

• How can I measure actual memory usage from my running processes?

  - by NullUser

  I have two servers, server1 and server2. Both of them are identical HP blades, running the exact same OS (RHEL 5.5). Here's the output of free for both of them: ### server1: total used free shared buffers cached Mem: 8017848 2746596 5271252 0 212772 1768800 -/+ buffers/cache: 765024 7252824 Swap: 14188536 0 14188536 ### server2: total used free shared buffers cached Mem: 8017848 4494836 3523012 0 212724 3136568 -/+ buffers/cache: 1145544 6872304 Swap: 14188536 0 14188536 If I understand correctly, server2 is using significantly more memory for disk I/O caching, which still counts as memory used. But both are running the same OS and if I remember correctly, I configured both with the same parameters when they were installed. I did a diff on /etc/sysctl.conf and they are identical. The problem is, I am collecting memory usage and other metrics over a period of time, (eg: vmstat, iostat, etc.) while a load is generated on the system. The memory used for caching is throwing off my calculations on the results. How can I measure actual memory usage from my running processes, rather than system usage? Is used - (buffers + cached) a valid way to measure this?

• Are ZFS snapshots + S3 a viable backup system for several VMs and general fileserver storage?

  - by AllanA

  I've been tasked with setting up a backup system for my small office (around 12 people). Most of our production stuff is on the AWS cloud, so what I need to back up are some small office/development files (under 100G right now), plus our operational VMs and development, which round out to a bit under 1T. I just need something reliable, convenient, and straightforward. I'm comfortable with Linux, FreeBSD, and to some extent Solaris 10, so I'm leaning toward a full server rather than an appliance system ala Openfiler or FreeNAS. What I'm contemplating is a small fileserver for general storage and nightly backups of the virtual machines, followed up by an offsite backup to Amazon's S3 storage service. It'd be the usual incremental backups nightly and full backup weekly. My question is if using ZFS snapshots, both locally and dumped to S3 via 'zfs send [-i]', is a viable backup tool? Or should I stick to using Duplicity, or some other method entirely? ZFS snapshots on the internal fileserver/backup machine sound like a perfect way to provide quick and convenient data recovery, so I'm likely to go with that for local redundancy. (If you folks see scenarios where relying on ZFS snapshots would be worse than a more traditional archiving backup, feel free to convince me.) But are snapshots flexible enough to lean on for recovery from the loss of my backup server? Or am I better off with something more traditional? (feel free to recommend free or commercial backup solutions you favor.)

• Website latency and bad tcp packets

  - by Mistero Lupo

  I have multiple websites hosted on a Linode VPS and I'm having an issue with one of them: every page that I try to load has about 10 seconds latency. Apache logs are clean and the other websites on the same machine are running well. At a first glance I tought it was a memory problem since the VPS has got only 512M, but from the linode dashboard CPU and Disk I/O are normal. Anyway here we have the ram status: $ free -m total used free shared buffers cached Mem: 487 463 23 0 2 55 -/+ buffers/cache: 404 82 Swap: 255 155 100 Only 23M free, but if it was a memory problem why other websites are going as usual? I took a live capture with wireshark, and there are some duplicates SYN ACK packets just before the 10 seconds gap. I'm out of ideas, looking for some clues. Wireshark live capture screenshot As you can see from the image, the gap is after the last bad tcp. Thank you in advance. UPDATE I've checked Apache2 logs in debug error level, and this is where something is appening: 151.97.156.191 - - [14/Nov/2012:11:19:40 +0100] [www.fmaisi.it/sid#7f32c625a220][rid#7f32c6801578/subreq] (3) [perdir /home/fmaisi/sites/www.fmaisi.it/public_html/] applying pattern '^index\.php$' to uri 'index.php' 151.97.156.191 - - [14/Nov/2012:11:19:40 +0100] [www.fmaisi.it/sid#7f32c625a220][rid#7f32c6801578/subreq] (1) [perdir /home/fmaisi/sites/www.fmaisi.it/public_html/] pass through /home/fmaisi/sites/www.fmaisi.it/public_html/index.php 151.97.156.191 - - [14/Nov/2012:11:19:54 +0100] [www.fmaisi.it/sid#7f32c625a220][rid#7f32c6537c78/initial] (3) [perdir /home/fmaisi/sites/www.fmaisi.it/public_html/] strip per-dir prefix: /home/fmaisi/sites/www.fmaisi.it/public_html/wp-content/plugins/wp-filebase/wp-filebase_css.php -> wp-content/plugins/wp-filebase/wp-filebase_css.php 151.97.156.191 - - [14/Nov/2012:11:19:54 +0100] [www.fmaisi.it/sid#7f32c625a220][rid#7f32c6537c78/initial] (3) [perdir /home/fmaisi/sites/www.fmaisi.it/public_html/] applying pattern '^index\.php$' to uri 'wp-content/plugins/wp-filebase/wp-filebase_css.php' As you can see there is a gap of 14 seconds after the pass through of index.php.

• Mysterious swap usage on EC2

  - by rusty

  We're in the middle of a project to move our infrastructure from a co-lo situation into Amazon EC2 and we've noticed some weird memory characteristics of the processes in our setup. Without going into too much detail about the specifics of our processes, we've noticed that on our EC2 instances "top" will show processes using a lot of swap space -- in fact, much greater than the amount of available swap or (if you add it all up) more than the available disk. Here's a sample top output: Mem: 7136868k total, 5272300k used, 1864568k free, 256876k buffers Swap: 1048572k total, 0k used, 1048572k free, 2526504k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ SWAP COMMAND 4121 jboss 20 0 5913m 603m 14m S 0.7 8.7 3:59.90 5.2g java 22730 root 20 0 2394m 4012 1976 S 2.0 0.1 4:20.57 2.3g PassengerHelper 20564 rails 20 0 2539m 220m 9828 S 0.3 3.2 0:23.58 2.3g java 1423 nscd 20 0 877m 1464 972 S 0.0 0.0 0:03.89 876m nscd You can see, for instance, that jboss is reportedly using 5.2 gigs of swap space which is definitely impossible since there's only 1G allocated and none is being used (probably because there's still 1.8G of RAM free). And here's the results of uname -a: Linux xxx.yyy.zzz 2.6.35.14-106.53.amzn1.x86_64 #1 SMP Fri Jan 6 16:20:10 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux We're running an AMI based off of the default Amazon Linux AMI (Amazon Linux AMI release 2011.09, so some RHEL5 and RHEL 6) with not too many customizations and definitely no kernel-level customizations. Something here tells me that on this particular kernel/distribution, the reporting of swap or maybe even total memory usage isn't what it appears to be... Any help would be appreciated!

• How to find out which process is hogging the linux server?

  - by user1149518

  We have a RHEL server. Today it suddenly became slow. Symptoms - It was responding slow to ping queries from other server. When I try to login using ssh, it was taking about 10 seconds to login. I was able to resolve the problem by doing some guess work. I killed one process which I thought was culprit. Which resolved the problem. Though I would like to know what's proper approach to detect the culprit in such kind of "slow server" situations. Le me know proper way to resolving such slowness issues and decting the process causing the slowness.

• New Servers Active Directory and Exchange

  - by user3164638

  I have 3 Dell PowerEdge server, each with 2 quad-core processors. I am going to bring this office out of the stone-age network (P2P, share files on a flash drive, emails through Google, etc) and set up Active Directory and Exchange 2013. Our needs are not that great at the moment - our staff consists of approximately 40 people, and our network may eventually be managed by an external company. We need only one domain for our emails (though we may serve emails for a few other partners domains as well). I was thinking of setting something up like this: Server 1: Primary DC. Active Directory and Exchange on separate virtual machines. Server 2: Redundant of server 1. Server 3: Shared resources, storage, backups, etc. How would you utilize 3 servers for an Active Directory / Exchange setup for a small/medium office? We do have plans to grow, so my solution must be scalable, though I'm not sure that I want to split permissions, though I'd consider it if that was something that could be changed on down the road.

• Can't create system image. 0x80780119 error after upgrade from 8 to 8.1

  - by cichy202

  I have upgraded my Windows 8 PC to 8.1 yesterday and it seemed like everything is working fine until I tried to create System Image. I got an error 0x80780119 saying that there is to little space on one of the partitions. I started looking into this problem and indeed one of the partitions does not meet the requirements. There are following partitions on my drive: DISKPART> list partition Partition ### Type Size Offset ------------- ---------------- ------- ------- Partition 1 Recovery 300 MB 1024 KB Partition 2 System 100 MB 301 MB Partition 3 Reserved 128 MB 401 MB Partition 4 Primary 74 GB 529 MB Partition 5 Primary 390 GB 75 GB Partition 1 has only 13MB free space. Partition 2 has 70MB free space, partition 3 is MSFTRES, partition 4 is my C drive with around 35GB free and partition 5 is not included in system image. Partitions were create like this during installation of Windows 8 - clean install from scratch. I am using UEFI so the drive is GPT formatted. So I thought, OK I can resize my C drive a little, move the partitions and expand the 1st one. I tried using GParted but it is not able to move the MSFTRES partition. It does not recognize the file system on it. So the question is: Is it possible to "clean up" the 1st partition in anyway? If not, is there anything special about MSFTRES partition? Or can I just remove it and create it a little further and just flag it as msftres with GParted?

• Will learning to use Fedora also teach me my way around Redhat (CentOS)?

  - by Matt Untsaiyi

  I want to dive into the open source world and start using a Linux distro while learning to program. I've looked over the options and it pretty much boils down to Fedora or CentOS. The reasoning behind it is I'm hoping to kill two birds with one stone... Redhat seems to be "the choice" for servers, so I figure as I learn to program, I can also learn my way around Linux... or Redhat more specifically... and get that under my belt too. I want to use Fedora, and be on the frontier of new software (since I'm not doing anything critical), but if it's completely different than Redhat I'd rather just use CentOS. So is it? Or can I use one and know the other?

• Make call with alternate provider if NOANSWER

  - by adaptive

  I have two voip providers, one free an the other paid. The free provider only allows local calls to certain area codes, so I need to fall back to the the paid provider if a call fails. At the moment, I have the following context in my extensions.conf file: [globals] ; freephoneline.ca PRIMARY_PROVIDER=fpl ; voip.ms SECONDARY_PROVIDER=voipms [local] exten => _NXXNXXXXXX,1,Set(CALLERID(name)=${OUTGOING_NAME}) exten => _NXXNXXXXXX,n,Dial(SIP/${EXTEN}@${PRIMARY_PROVIDER}) exten => _NXXNXXXXXX,n,Set(CALLERID(num)=${OUTGOING_NUMBER}) exten => _NXXNXXXXXX,n,Dial(SIP/1${EXTEN}@${SECONDARY_PROVIDER}) exten => _NXXNXXXXXX,n,Hangup() I checked the logs and noticed that the free provider responds with NOANSWER if a call is not allowed (Even though it plays a message). What I want is to: Try calling the ${PRIMARY_PROVIDER} first. If NOANSWER is returned by provider (not that the callee did not answer), then call with ${SECONDARY_PROVIDER} How can I modify my dial plan to get the desired results? EDIT : The primary provider is freephoneline.ca, and I'm using asterisk v1.8.2.3-2

• DHCP misbehavior

  - by Peregrino69

  ISC DHCP Server is running on Fedora 10. Since it's doing nothing else nobody bothered updating it... I've noticed behavior that looks very strange to me: the DHCP server gets a DISCOVER as broadcast, sends OFFER as unicast to the DHCP relay - and immediately afterwards sends the same offer as a bcast. The client itself is misbehaving, it's continuously sending DHCP DISCOVER packets, but I don't think that could cause the server to bcast the offer. Does anyone have any idea why this might happen - is it maybe a feature of this stone-age server?

• What's the best project management software for internal dev. 5 man shop

  - by P.Brian.Mackey

  I work for a large corporation, but we do small intranet web application development. Our project management tracking sucks. Its custom software built by a jr. intern. For what its worth, our development style is akin to agile, but there's nothing set in stone...very customer oriented approach. I need project tracking that meets the criteria: Intranet, internal products. Mostly maintenance, some new development. 5 developers 12 products 1 hands-off manager. He really just wants to know estimated man hours, due date for dev, QA and release. Along with a short description of the project. Free or super cheap. Bonus Simple pretty UI. Think pretty charts. Hope I covered everything. Please ask for any clarification. If you read dreaming in code, the company uses some project tracking software that sounds pretty sweet. Note, we do have Team Foundation Server. I already tried pushing its use as PM tracking, but its too complicated. I can't get people to sit and train. So this software has to be easy.

• First Minecraft mod not working: make a new sword

  - by yamikoWebs

  I am making my first mod and cannot see what is wrong with it. I am using MCP and Modloader. For my first mod I was going to make swords. I started with making a new EnumToolMaterials WOOD(0, 59, 2.0F, 0, 15), STONE(1, 131, 4.0F, 1, 5), IRON(2, 250, 6.0F, 2, 14), LAPIS(3, 750, 7.0F, 2, 14), OBSIDIAN(3, 1000, 7.5F, 3, 12), EMERALD(3, 1561, 8.0F, 3, 10),//diamond GREEN(3, 2000, 9.0F, 4, 10),//emerald GOLD(0, 200, 12.0F, 0, 22); then here is the mod class public class _Mod_Yamiko extends BaseMod{ /* mod itemts */ public static final Item swordLapis = (new ItemSword(600, EnumToolMaterial.LAPIS)).setItemName("swordLapis"); public static final Item swordObsidian = (new ItemSword(601, EnumToolMaterial.OBSIDIAN)).setItemName("swordObsidian"); public static final Item swordGreen = (new ItemSword(602, EnumToolMaterial.GREEN)).setItemName("swordGreen"); public void load(){ //set images swordLapis.iconIndex = ModLoader.addOverride("/gui/items.png","/gui/swordLapis.png"); ModLoader.addName(swordLapis, "Lapis Sword"); //craft ModLoader.addRecipe(new ItemStack(_Mod_Yamiko.swordLapis, 1), new Object[]{ " X ", " X ", " Y ", 'X', Block.dirt, 'Y', Item.stick }); } public String getVersion(){ return "0.1"; } } Then I made a 16×16 .png image. I am not sure where to save it so I recompiled and reobfuscated, took the mod files and put it in my local Minecraft install, added the image where it be should be. No problems when playing but I cannot make the new sword.

• Random World Generation

  - by Alex Larsen

  I'm making a game like minecraft (although a different idea) but I need a random world generator for a 1024 block wide and 256 block tall map. Basically so far I have a multidimensional array for each layer of blocks (a total of 262,114 blocks). This is the code I have now: Block[,] BlocksInMap = new Block[1024, 256]; public bool IsWorldGenerated = false; Random r = new Random(); private void RunThread() { for (int BH = 0; BH <= 256; BH++) { for (int BW = 0; BW <= 1024; BW++) { Block b = new Block(); if (BH >= 192) { } BlocksInMap[BW, BH] = b; } } IsWorldGenerated = true; } public void GenWorld() { new Thread(new ThreadStart(RunThread)).Start(); } I want to make tunnels and water but the way blocks are set is like this: Block MyBlock = new Block(); MyBlock.BlockType = Block.BlockTypes.Air; How would I manage to connect blocks so the land is not a bunch of floating dirt and stone?

• 8 Reasons to Attend Oracle OpenWorld 2012

  - by kgee

  Every year, the Oracle Hardware team recognizes the unique buzz that accompanies the season of OpenWorld. During the late nights kept possible by the grace of caffeine combined with the stress and eagerness for the event to run smoothly, we like to remind ourselves of why all our hard work is going to pay off. So, now that we've registered, here are some of our top reasons that we’re excited for Oracle OpenWorld 2012: The KeynotesJust to name a few...Larry Ellison, Mark Hurd, Thomas Kurian, John Fowler and many more are speaking live. We're expecting to walk away from the keynotes with a new frame of reference on a vast array of hot topics. NetworkingWhether it's through means of the OpenWorld Lounges, social media, or bars and cafes around Moscone Center, we'll be surrounded by people who are experts in the hardware field. Hardware SessionsThere are enough sessions to satisfy every Oracle hardware knowledge need. Hardware Experts in GeneralSo many experts that we wish we could be in two places at once sometimes. Pearl Jam & Kings of LeonRock out with these two legendary bands at the Oracle Appreciation Event! Oracle Music FestivalJoss Stone, Macy Gray, the Hives, and Jimmy Cliff will be welcome escapes at the end of each day at OpenWorld, and are just a couple more reasons these all nighters before OpenWorld are worth it. ORACLE TEAM USA and the America's Cup trophyAfter the sailors take on San Francisco Bay for Fleet Week, we’ll be soliciting them for autographs and taking pictures with them at OpenWorld. Location, Location, LocationThe Moscone Center is beautiful and in the best location in San Francisco. We know the OpenWorld hype will get to us sometimes, and it's nice to know that we have pretty much everything San Francisco has to offer at our finger tips. Why are you excited for #OOW? Tell us why!

• Generalist Languages: Dying or Alive and Well?

  - by dsimcha

  Around here, it seems like there's somewhat of a consensus that generalist programming languages (that try to be good at everything, support multiple paradigms, support both very high- and very low-level programming), etc. are a bad idea, and that it's better to pick the right tool for the job and use lots of different languages. I see three major areas where this is flawed: Interfacing multiple languages is always at least a source of friction and is sometimes practically impossible. How severe a problem this is depends on how fine-grained the interfacing is. Near the boundary between the two languages, though, you're basically limited to the intersection of their features, and you have to care about things like binary interfaces that you usually wouldn't. Passing complex data structures (i.e. not just primitives and arrays of primitives) between languages is almost always a hassle. Furthermore, shifting between different syntaxes, different conventions, etc. can be confusing and annoying, though this is a fairly minor complaint. Requirements are never set in stone. I hate picking a language thinking it's the right tool for the job, then realizing that, when some new requirement surfaces, it's actually a terrible choice for that requirement. This has happened to me several times before, usually when working with languages that are very slow, very domain specific and/or has very poor concurrency/parallelism support. When you program in a language for a while, you start to build up a personal toolbox of small utility functions/classes/programs. The value of these goes drastically down if you're forced to use a different language than the one you've accumulated all this code in. What am I missing here? Why shouldn't more focus be placed on generalist languages? Are generalist languages as a category dying or alive and well?

• Breakout ball collision detection, bouncing against the walls

  - by Sri Harsha Chilakapati

  I'm currently trying to program a breakout game to distribute it as an example game for my own game engine. http://game-engine-for-java.googlecode.com/ But the problem here is that I can't get the bouncing condition working properly. Here's what I'm using. public void collision(GObject other){ if (other instanceof Bat || other instanceof Block){ bounce(); } else if (other instanceof Stone){ other.destroy(); bounce(); } //Breakout.HIT.play(); } And here's by bounce() method public void bounce(){ boolean left = false; boolean right = false; boolean up = false; boolean down = false; if (dx < 0) { left = true; } else if (dx > 0) { right = true; } if (dy < 0) { up = true; } else if (dy > 0) { down = true; } if (left && up) { dx = -dx; } if (left && down) { dy = -dy; } if (right && up) { dx = -dx; } if (right && down) { dy = -dy; } } The ball bounces the bat and blocks but when the block is on top of the ball, it won't bounce and moves upwards out of the game. What I'm missing? Is there anything to implement? Please help me.. Thanks
