  • Http-Only cookies in WebLogic: what versions support them/how and why are they supported?

    - by John
    We want to make all cookies set by our webapp http-only. I only have a basic understanding of the benefits of doing this but I'm told by security people that it's a Good Thing (tm) Our app is running under JDK1.6.05 and WebLogic10.3.0 After way too much digging around Oracle's website for documentation, I've found good evidence that the first version of WebLogic to support http-only cookies is 10.3.1. By "support," I mean the cookie-http-only deployment-descriptor element. Before we go about upgrading, I'd be nice to have these questions answered: 1a) Is it accurate that WL10.3.1 is the first version to support http-only cookies and that we're out of luck with 10.3.0? 1b) If we do indeed need to upgrade, is there an easy to do so under Windows? I've heard people mention an "upgrade jar" that you just stick in the classpath but I can't find any mention of this by Oracle. Does an easy way exist, or do we need to do a full-install of the new version? 2) What does the cookie-http-only deployment-descriptor element do when enabled? Will it ensure all cookies set by the application have an http-only=true attribute? Will it do more or less? Is there anything I'll have to do programmatically? 3) Is there anything in general I should know about http-only cookies, getting my web app to take advantage of them, or other security concerns?

  • Which project management software for technophobes who've never worked with something like that?

    - by Ernst
    Hi, Our director has asked me to get something to manage projects. Note that so far we haven't used anything of the sort. I did not get very clear instructions yet, probably because she doesn't know exactly what we need either. My guess is, we'll only find out while using something. I've looked at some, openworkbench, ganttproject, and microsoft project. The latter has the advantage of easy importing of users from exchange, are there others that do that (even if not directly, easily)? I don't think it's a critical requirement though. We're using some other custom software where I have to add users manually anyway and we're small enough that it's maybe once a month that I have to add or remove a user. In any case, I'm not in favour of buying anything, since I'm skeptic about us actually succeeding in putting it to good use, and even if we do, we will only during usage discover what we need. We're also not a tech shop, most people vary from not very technically adept to technophobic. This means we need something very userfriendly. I prefer to stay away from online solutions, since we deal with sensitive information and I prefer to keep that in house, but I guess it would be acceptable for the trial period. An intranet site is an option though, but preferably something that is easy to set up with IIS. Xplanner plus and redmine I found too hard to set up for this experiment. Some other options I haven't yet tried to install, but which look to complex for our technophobes: Endeavour Software Project Management, Project-Open, Trac. Any suggestions? Thanks, Ernst

  • Linux virtualization choices with graphic acceleration / video card support

    - by Urbn
    I am in the process of building a new desktop machine for work and fun. I am looking to run a undecided flavor of Linux (guessing Ubuntu) as my primary OS and several Windows installs with a Windows 7 install for .net development and gaming as virtualized environments. From my previous experiences with virtualization software in Linux I was never able to find an application that offered descent video card support / graphic acceleration etc. to be capable of playing any games within one of the virtualized environments. And since I will be investing quite a bit of money into this system for gaming I would naturally want to find the best option available to achieve this setup. So Onto my question: Is there any virtualization software available for Linux that has full video card support, graphic acceleration and capable of taking advantage of everything the video cards have to offer within the virtualized environments? Or am I stuck with running Windows 7 as my primary OS and using virtualization for Linux and the other OS's? Also I have no preference on open/closed source and price range would be up to $175.00 to support at least 3 virtualized environments.

  • How do you optimize your Outlook Exchange + IMAP setup?

    - by Mike
    My company provides an Outlook/Exchange account we must use for mail/calendar. Like many companies, they unfortunately also provide a ridiculously small mail quota. I got tired of managing and backing up .pst files (since I'm always in my e-mail there is never a good time to back it up), so I started storing my archived mail "in the cloud", using an IMAP server I set up on my Linux box. This has a few drawbacks for me: IMAP (at least the implementation in Outlook) is *very slow*. Furthermore, if I move a large number of messages to the IMAP server, it blocks the entire Outlook client for hours sometimes, which is quite annoying. Can't use exchange over HTTP to do mail without launching a VPN session, because the client-side rules I have which organize my mail fail and disable the rule if the IMAP server can't be reached. If I reply to a message from my IMAP store, I have to specify a SMTP server willing to relay for me in order to send e-mail, unless I always remember to select my Exchange account while composing e-mail. ... but the main advantage of being very easy to back up, with a couple of cron jobs that essentially do an 'rsync'. Short of moving the IMAP server to my local host (which seem like might have the same file locking problems as using a .pst), my options seem limited for solving (1). I'd like to come up with a solution for (2) and (3) though. For problem (2) would it be possible to somehow tell Outlook that the IMAP server is "offline", and have it synchronize my changes during a periodic "send and receive"? If so, I wonder if it would block the Outlook client, like it does in problem (1), and if it would be compatible with the client-only rules I use to sort my mail into folders. I've looked all over the options menu and have not found a way to tell Outlook to not use a certain account for sending mail, which would solve (3). Is anyone else crazy enough to be doing something like this? Any ideas?

  • Could I use Windows 7 instead of Windows SBS 2008 for this server?

    - by Ecyrb
    First off, I'm not a sys admin. I'm just a software developer trying to help out my parents' small business. Right now they have one server, a domain controller with a P4 processor running SBS 2003. They also have this machine hosting QuickBooks, MySQL for the old version of an app, and SQL Server 2008 Express for the new version of the app (which will replace the old eventually). They've been complaining about the workstations being slow so I figured it might help if they bought a new server and moved QuickBooks, MySQL, and SQL Server to the new server, leaving the old server as just a DC. In trying to pick an operating system for their new server, I was thinking about Windows SBS 2008 Standard with enough licenses for seven machines. But that's a lot more money than they're going to want to spend. So then I wondered if there's any real advantage to having a server OS as opposed to just throwing Windows 7 on the new server. It's a lot cheaper and I can't think of any SBS features that it would need if it's just hosting QuickBooks, MySQL, and SQL Server. Would it be okay to use Windows 7 for a server like this? Are there any advantages to using SBS 2008 that I would be missing out on? Any additional tips are much appreciated!

  • How to create a mysql database that can contain any character, also different languages

    - by Jakke
    I'm trying to create a database that has to contain articles in different languages. I'm using Mariadb as my server and I know bits of SQL. My knowledge doesn't really cover details like the differences between engines like MyISAM, InnoDB etc or character sets like utf8/16/32, latin 5/7/etc. I do know that the character set has importance, I guess what I'm looking for is an all-encompassing character set and an engine that best deals with this type of content. Also, is there an advantage in storing articles in multiple data rows (equivalent of different pages) to make things a little faster, or would you store a whole article in a single data row. Or does that depend on the size of the articles? Sorry for my noobish question, I know the information is all out on the internet but it would take me quite a long time to research and get a grip on everything. Would be cool if someone with experience could give me a little head start and point me in the right direction. This is for a intranet site, consider the content to be somewhat like a blog (and no, I don't want wordpress or something similar at this point). Not sure if it matters, but I tend to create and manipulate my tables with phpmyadmin, I use apache as web server and it all runs on Linux.

  • Scenario - NTFS Symbolic Link or Junction?

    - by Unsigned
    Differences Absolute Relative File Directory UNC Symbolic link ? ? ? ? ? Junction ? x x ? x Scenario Let's assume we're creating a reparse point to create the redirect C:\SomeDir => D:\SomeDir Since this scenario only requires local, absolute paths, either a junction or symlink would work. In this situation, is there any advantage to using one or the other? Assume Windows 7 for the OS, disregarding backward-compatibility (prior to Vista, symlinks are not supported). Update I have found another difference. Symbolic Link - Link's permissions only affect delete/rename operations on the link itself, read/write access (to the target) is governed by the target's permissions Junction - Junction's permissions affect enumeration, revoking permissions on the junction will deny file listing through that junction, even if the target folder has more permissive ACLs The permissions make it interesting, as symlinks can allow legacy applications to access configuration files in UAC-restricted areas (such as %ProgramFiles%) without changing existing access permissions, by storing the files in a non-restricted location and creating symlinks in the restricted directory.

  • Is 1GB + 1GB RAM better than 2GB +0.5GB?

    - by pibboater
    My laptop has two slots for RAM, and currently has two 512 MB chips, for 1 GB. Windows XP is running terribly slow on it, so I want to upgrade the RAM. I could buy two 1 GB chips to replace both of the current 512 MB chips, to give me 2 GB of RAM. Or, the price is the same to buy one 2 GB chip, to replace just one of the 512 MB chips, and give me 2.5 GB total. The RAM it takes is PC2-4200 533MHz DDR2. What do you think would be better: buying two 1 GB chips so it can take advantage of dual-channel operation, or buying one 2 GB chip to end up with more total RAM but not dual-channel operation? Like I said, price is the same, so performance is the only consideration. I'm not doing anything especially intensive like video or photo editing -- just having multiple Office programs open, playing music, browsers, etc., but currently even opening the first application takes forever. If it matters, the laptop is a Toshiba Qosmio G25-AV513 running Windows XP Media Center SP3. Thanks! Kevin

  • How do you recreate the System Recovery environment in Windows 7?

    - by Howiecamp
    I'm running Windows 7 Home Premium RTM (64-bit) and I want to take advantage of the system recovery tools (eg the Command Prompt) without using the Windows 7 DVD. My understanding is that this environment (WinRE) should be installed to your HDD by default as part of the Windows 7 installation. However, when I hit F8 on boot and select "Repair", I get: Windows failed to start. A recent hardware or software change might be the cause. To fix the problem... Status: 0xc000000e Info: The boot selection failed because a required device is inaccessible. The "Info" line seems like the smoking gun. My next step was to boot from the Windows 7 DVD, and choose "Repair". It indicated my Recovery Environment wasn't on the Windows 7 boot menu (perfect) and offered to fix it. I said yes and rebooted, however same issue as above. In addition, when I booted in to Windows 7 and I looked at the boot menu options, the recovery/repair option was not there. Only my Windows installation. Finally, I ran the Disk Management tool (diskmgmt.msc) and took a look at the contents of my "System Reserved" partition (which was set to "Active" as normal). It's unclear to me what the contents should look like, however it is my understanding that the WinRE environment gets installed to this partition. (As part of the above troubleshooting I followed http://superuser.com/questions/25728/how-to-fix-windows-7-boot-process which lead to http://www.sevenforums.com/tutorials/668-system-recovery-options.html).

  • when to upgrade server to include more cores, versus more processors, versus additional server?

    - by gkdsp
    The server hosting market is separated into single, double, qual, etc., processors, where each processor has several cores, or CPUs. My company will offer a Linux-based web application that relies on an Apache web server and a middle tier for business logic. The middle tier is used to crunch math, and return result to a client. Many clients may access the application simultaneously. The company will start with one processor having 4 cores. I'm trying to understand how the app uses the cores and then how to scale the application as business grows, in terms of servers/processors/cores. For example, I'd assume initially one core would be used for Apache, and the other 3 used to process client's requests for math crunching... Question 1: does that mean, with the 3 cores available, I can handle 3 separate client requests simultaneously (e.g. 1 for each of 3 cores)? I mean, except for the shared RAM, is this effectively like having 3 individual machines (from pt of view or processing client requests simulaneously)? Or, only one client's request may be processed at any one time, but that client's request is divided up into up to 3 cores depending on the type of process running that does the math crunching and whether or not it can take advantage of multi threading (so the # of cores impacts how fast any one client request completes)? I'm confused about what the cores mean to the application here. Question 2: As the business grows and more client requests need to be processed, should the server be upgraded to (A) a new machine with more cores, (B) a new machine with two processors, 4 cores each, or (C) keep the original server and add another server with a single processor? Which route provides the most efficient way to scale the application, in terms of processing more client requests per time interval? Is the choice, for example, limited by RAM (when you need more RAM than box can handle it's time to add another server), or something else? Question 3: Is the total number of client requests processed simultaneously equal to the number of cores times the number of servers (minus the one core for Apache)?

  • When to raise domain functional level?

    - by Joel Coel
    We very recently completed a project to retire two old domain controllers running Server 2003 R2. They are now replaced with shiny new 2008 R2 boxes. However, the functional level of the domain has not yet been updated for the 2008 R2 servers, just in the long-shot case of the need for a rollback to the old controllers. I expect to have the all clear to update the domain by next weekend. I also want to note that our desktop clients are still 95% Windows XP. However, we're about to start a project to update our 200 or so clients to Windows 7 before the end of the calendar year. Is there any advantage to holding the domain at the 2003 functional level while we are still supporting more Windows XP than Windows 7, especially given that some of the management stations are still XP? Update: I forgot to mention earlier that we still have a pair of windows 2000 servers (not domain controllers) that support some legacy software. I'm working to replace those, but in the meantime I need to be sure that Windows 2000 can still participate in a 2008 R2 domain.

  • How to use LVM on Rackspace Cloud

    - by batrick
    Dear all, I am trying to set up a simple but effective solution to make a backup of my rackspace cloud servers. These servers each run subversion, trac, and some database-backed custom php applications. My idea is to set up a LVM and mount a volume under, say, /srv. In this volume, I keep the data from all applications. Instead of caring about how to back-up each app in a different way (svn hotcopy, trac-admin hotcopy, huge mess for mysql), I simply take an LVM snapshot and back this one up cloud files using the excellent cloudcity script (http://github.com/jspringman/cloudcity/blob/master/cloudcity). The advantage of this solution is that it is quick and easy, and LVM allows to make decent backups. As more apps are added, it should not be required to change the backup script much. The downside, and main point of my question here, is that I am not sure how to get LVM working on Rackspace cloud, because there is only one root volume and no service like Amazon's EBS. I was thinking it may be possible to create a large empty file and use this as a "physical volume". Has anybody done anything like this before? Or do you know why it can never work? It would be great to hear from you. Thanks, batrick

  • Ram configuration 4x4 or 2x8?

    - by Carl B
    I am looking to upgrade my Ram to 16gigs and I am wondering if there is any distinct advantage of the way I do it. That being a 4x4 or 2x8 set up. In all my searching there have been a number of pros for each profile. I can find no benchmarck results for either setup as a compaison. So, if there are 2 profiles of the same speed, same voltage, same timing and same cas what would perform better or have a better over all benafit? A few examples from my search - a 4x4 set would lend a benafit in that if one stick failed, you only lose 25% of your Ram vs 50% in a 2x8 set up. a 2x8 set up would have less strain on the memory controler and motherboard. a 2x8 would generate less heat. a 2x8 set up is easier to over clock (not part of my need, but alot of the comparisons circled around the overclocability ease of the 2 stick set up). There is one outstanding benafit that I have found in at least the target company I have looked at and that is price. The 2x8 is nearly half the cost. My motherboard supports a max of 16 gigs and I have a 64 bit OS. Has anyone seen any performance comparisons or is 16 gb just 16 gb no matter how you slice it? And is there any merit to the above pros? Edit: as per the mobo specs - Main Memory • Supports four unbuffered DIMM of 1.5 Volt DDR3 800/1066/1333/1600*/1800*/2133* (OC) DRAM, 16GB Max

  • How would I change the DocumenRoot on the version of Apache that came pre-installed on my Mac OS X s

    - by racl101
    OK, so I want to take advantage of the Apache server that comes installed on my Mac OS X system (which means, I would like not to have to install my own version of Apache since I might as well tryto use what comes bundled), and as such, I went to change some settings in the configuration file: /etc/apache2/httpd.conf Namely, I changed the these two lines: DocumentRoot "/Users/myusername/Sites" <Directory "/Users/myusername/Sites"> So that they initially pointed to a folder in my Dropbox folder (so I could have my docs sync to my Dropbox): DocumentRoot "/Users/myusername/Dropbox/public_html" <Directory "/Users/myusername/Dropbox/public_html"> That didn't work. So then I figured, ok maybe it was too much to ask to make folder in my Dropbox be my document root. So then I thought, what if I make the Document root another folder of my choosing like so: DocumentRoot "/Users/myusername/dev-sites/public_html" <Directory "/Users/myusername/dev-sites/public_html"> and that didn't work either. After looking within the httpd.conf file for clues it seems that only two directories appear to work as Document root paths for the Apache that comes bundled with Mac OS X: /Users/myusername/Sites (or ~/Sites) and /Library/WebServer/Documents/ But trying to use any other directories didn't seem to work. I would get 403 errors on my browser. I was wondering if there was some other settings to change on the httpd.conf file or any permissions to set to make this work. Any help would be appreciated and many thanks in advance.

  • What are the typical methods used to scale up/out email storage servers?

    - by nareshov
    Hi, What I've tried: I have two email storage architectures. Old and new. Old: courier-imapds on several (18+) 1TB-storage servers. If one of them show signs of running out of disk space, we migrate a few email accounts to another server. the servers don't have replicas. no backups either. New: dovecot2 on a single huge server with 16TB (SATA) storage and a few SSDs we store fresh mails on the SSDs and run a doveadm purge to move mails older than a day to the SATA disks there is an identical server which has a max-15min-old rsync backup from the primary server higher-ups/management wanted to pack in as much storage as possible per server in order to minimise the cost of SSDs per server the rsync'ing is done because GlusterFS wasn't replicating well under that high small/random-IO. scaling out was expected to be done with provisioning another pair of such huge servers on facing disk-crunch issues like in the old architecture, manual moving of email accounts would be done. Concerns/doubts: I'm not convinced with the synchronously-replicated filesystem idea works well for heavy random/small-IO. GlusterFS isn't working for us yet, I'm not sure if there's another filesystem out there for this use case. The idea was to keep identical pairs and use DNS round-robin for email delivery and IMAP/POP3 access. And if one the servers went down for whatever reasons (planned/unplanned), we'd move the IP to the other server in the pair. In filesystems like Lustre, I get the advantage of a single namespace whereby I do not have to worry about manually migrating accounts around and updating MAILHOME paths and other metadata/data. Questions: What are the typical methods used to scale up/out with the traditional software (courier-imapd / dovecot)? Do traditional software that store on a locally mounted filesystem pose a roadblock to scale out with minimal "problems"? Does one have to re-write (parts of) these to work with an object-storage of some sort - such as OpenStack object storage?

  • In need of assistance for recovering a lost partition

    - by Tek
    The program that has worked for the most part is Active@ Partition Recovery. I'm so close but yet so far from recovering my data. Okay so here's what happens. In the following screenshot (blanked out a folder and filename with profanity in case some of you guys are at work :P), it detects the partition I accidentally deleted with ALL 100% of my data listed. Of course, I didn't write ANY data to that drive after I did this. But when I click "recover" and finishes the recovery process, in Windows I click on the partition that was just was just recovered... It's EMPTY. The program seems to be able to see my lost files, but when I recover the partition windows doesn't seem to think the same =( Things I tried: I tried running a chkdsk /r /f after I recovered the partition, apparently it couldn't find any errors. Tried using other software like TestDisk to recover the partition, but they (all) act similar to Windows in that it detects the (missing) partition but when I browse it there's no files. The partition is there along with all the file and data information. The sector information is also in the screenshot, is there any way I can use this to my advantage in recovering my data? Other information: Dualboot: Win8 / Ubuntu 12.10 x64 1TB Internal desktop drive, GPT Layout, NTFS formatted drive, 64K allocation size.

  • Windows 8 "Upgrade Offer" eligibilty when running the Consumer Preview in a VM?

    - by Dan Harris
    If I have a VM running Windows 8 Consumer/Release Preview, am I allowed to take advantage of the Windows 8 upgrade offer, and install it on that machine? I would have assumed not...as there was never a licensed version of XP SP3 through to Windows 7 installed in that VM. It was a clean installation of the Consumer Preview into a VM. My confusion comes from the notes at the bottom of the download page for the Upgrade offer which states: Offer valid from October 26, 2012 until January 31, 2013 and is for individuals and small businesses needing to upgrade up to five devices. If you are a business customer looking to upgrade more than five devices to Windows 8 Pro, contact your Microsoft partner for more information. To install Windows 8 Pro, customers must be running Windows XP SP3, Windows Vista, Windows 7, Windows 8 Consumer Preview, or Windows 8 Release Preview. I am assuming it's not possible and i'll need to purchase the System Builder edition to install within a VM? My guess is that you can use your downloaded upgrade offer only if you updated Windows 7 to the release preview, and therefore had the Windows 7 license on the machine, I used the serial number from the Microsoft Website when downloading the Release Preview, and did a clean install, so there was never a Windows 7 license on the VM. I have MSDN for development purposes, but I am looking to run in a VM for personal use as well, so my MSDN license is not valid for that particular use.

  • PHP potential issues with compiling 5.3.8 extensions against RHEL 6 / CentOS 6 PHP 5.3.3 package

    - by user101203
    I'm working on getting a Red Hat 6 LAMP server going and while the PHP that comes with it has many extensions we use, it doesn't have all of them. To solve this, I was thinking about either compiling the PHP extensions which come in the ext folder of the downloadable source code of PHP 5.3.3 from php.net same as #1, but using the extensions from the latest PHP version (currently 5.3.8). Do #1 but manually decide which updates to backport from the latest version of the PHP extensions into the older version and then compile the backported result A drawback to #1 is that security and bug fixes come out which we wouldn't be able to take advantage of. A drawback to #3 is that it might be a lot of work Does anyone know what the drawbacks to #2 are? I don't want to go down that route if it might result in some unexpected negative outcomes. Also, are there any other drawbacks to the other options or a better way to go altogether? I want to use the PHP 5.3.3 which comes with the Linux distro because I don't want us to get to a place again where we are forced to upgrade to a new version of PHP to stay on top of security updates like from PHP 5.2.x to 5.3.x and there be backwards incompatible changes (this is the situation we're in now with PHP 5.2.x no longer being supported).

  • Splitting an HTTP request into multiple byte-range requests

    - by redpola
    I have arrived at the unusual situation of having two completely independent Internet connections to my home. This has the advantage of redundancy etc but the drawback that both connections max out at about 6Mb/s. So one individual outbound http request is directed by my "intelligent gateway" (TP-LINK ER6120) out over one or the other connection for its lifetime. This works fine over complex web pages and utilises both external connects fine. However, single-http-request downloads are limited to the maximum rate of one of the two connections. So I'm thinking, surely I can setup some kind of proxy server to direct all my http requests to. For each incoming http request, the proxy server will issue multiple byte-range requests for the desired data and manage the reassembly and delivery of that data to the client's request. I can see this has some overhead, and also some edge cases where there will be blocking problems waiting for data. I also imagine webmasters of single-servers would rather I didn't hit them with 8 byte-range requests instead of one request. How can I achieve this http request deconstruct/reconstruction? Or am I just barking mad?

  • What are the advantages of registered memory?

    - by odd parity
    I'm browsing for a few low-end servers for a startup and I'm a bit confused about the different memory types. The advantage of ECC is clear - single-bit error correction. When it comes to registered memory it seems more vague, especially in systems that support both registered and unbuffered memory. A Google search mostly finds copies of the Wikipedia article, which states that registered memory chips "...place less electrical load on the memory controller and allow single systems to remain stable with more memory modules than they would have otherwise". However I can't find any quantification of this. What I'm wondering about is: Is registered memory an improvement over unbuffered when it comes to soft error rate, or is it purely about the maximum number of modules supported? If yes, at what point (amount of modules or GB of memory) do these improvements start to become noticeable? For a specific example, the HP ProLiant DL 120 G6 server manual states that maximum supported memory configuration is 16 GB unbuffered (4x4GB) or 12 GB registered (6x2GB). In this case I'd rather have the extra 4GB of memory if the reliability difference is negligible.

  • Oracle: 1 Large Server vs. 2 Smaller Servers?

    - by nvahalik
    We are in the planning stages of setting up our production Oracle 10gR2 environment. Our budget gives us the ability to buy 2 processor licenses of Oracle DB Standard Edition. We have minimal experience with Oracle so I'll defer to anyone who has used it. We are trying to decide if we should set up a single dual quad-core box or 2 individual quad-core boxes in a RAC configuration. Our DB right now is about 60 GB, and at our peak, we'll have up to 150 concurrent users. Most of the big stuff is done via batch processing at night. My gut tells me that having 2 boxes in a RAC configuration can't be a bad thing because it provides a true hardware failover solution. DB stored in a shared LUN on a SAN via iSCSI. Plus if we ever need to add capacity, we already have boxes in place that can be upgraded with extra procs (I assume with zero downtime, since it's set up in a RAC config) if we add extra licenses, or RAM. Does RAC have any performance penalties? Will it add extra latency? Is there any true advantage for having dual processor boxes running these systems? If we build out the Oracle boxes with special hardware: hardware iSCSI cards, TOE NICs, will these boxes be solid? We are deploying on 64-bit Windows. So what would you do? One box or two?

  • 20 1TB drives vs. 10 2TB drives in RAID5/6 server

    - by Hunter
    Hi everyone, I will be setting up a server at work and I need some advice on some details. The setup will be one blade-type server (8-core, 16GB RAM) with two subsystems - one for the main storage the other to back it up. I'm shooting for a 20TB array (I know it'll be less after formatting and parity drives). So is there any advantage one way or the other with either 20 1TB drives or 10 2TB drives? I'm not sure right now how many controllers I should have either (in the quote I have is a dual-port controller). I would think two controllers for a server of this size would be a better choice than the dual-port controller (but I really don't know). And would an array of this size have any performance issues in RAID 5 or 6 (I know RAID 5 or 6 are "slower" because of all the parity calculations). Also, these will be either WD RE3 (1TB) or the RE4 (2TB). Oh, also, for the backup array would it be ok to use the WD 2TB green drives (also in RAID5 or 6)?

  • Efficient mirroring of directories using hardlinks

    I'm backing up my music collection on to a number of NTFS-formatted external hard-drives; however, as I store my main collection in FLAC and have my library on my laptop as MP3s to save space, I want to be able to back up both sets, because mass conversion between formats is time-consuming. The "music" directory can contain any format; the "mp3s" directory contains only MP3s converted from files in the "music" directory. The music collection on the laptop contains only MP3s, but they come from both sources. When I backup my laptop's library to the "mp3s" directory, I want to only copy across MP3 files that don't exist in the "music" directory; those that do should be hard-linked to the "music" directory. All directories have an identical hierarchy, sorted by artist, album, date, discnumber if applicable, etc, and I use a tagging editor to ensure consistency across all these locations. I'm also using a Linux computer, but keeping the music collections on NTFS-formatted partitions so that they are readable by both Linux and Windows. At the moment, I use the following command to perform the backups, but this is time-consuming due to the expensive nature of finding hard links. rsync -avu --progress --relative --ignore-existing --link-dest=../music/ **/*.mp3 /media/ntfspocket/mp3s Is there a way to perform this backup more efficiently, taking advantage of the directory hierarchy?

  • How to find an entry-level job after you already have a graduate degree?

    - by Uri
    Note: I asked this question in early 2009. A couple of months later, I found a great job. I've previously updated this question with some tips for whoever ends up in a similar situation, and now cleaned it up a little for the benefit of the fresh batch of graduates. Original post: In my early 20s I abandoned a great C++ development career path in a major company to go to graduate school and get a research masters (3 years). I did another year in industrial research, and then moved to the US to attend graduate school again, getting another masters and a Ph.D in software engineering from a top school (another 6 years down the drain). I was coding the whole way throughout my degrees (core Java and Eclipse plug-ins) and working on research related to software engineering (usability of APIs). I ended up graduating the year of the recession, with a son on the way and the prospects of no healthcare. Academic jobs and industrial research jobs are quite scarce. Initially, I was naive, thinking that with my background, I could easily find a coding job. Big mistake. It turns out that I'm in a complicated position. Entry level positions are usually offered to college undergraduates. I attended my school's career fairs, but you could immediately see signs of Ph.D. aversion and overqualification issues. Some of the recruiters I spoke with explicitly told me that they wanted 20 year olds with clean slates, and some were looking for interns since they are in various forms of hiring freezes. I managed to get a couple of interviews from these career fairs and through recruiters. However, since I've been out of school for a long time and programming primarily in Java, I am also no longer proficient in C/C++ and the usual range of college-level interview questions that everyone uses. I had no problems with this when I was 19 and interviewing for my first job since a lot of what you do in C is manipulate pointers and I was coding C++ for fun and for school. Later I was routinely doing pointer manipulation on the job, and during my first masters taught college courses with data structures and C++. But even though I remember many properties of C++ well, it's been close to ten years since I regularly used C++ and pointers. As a Java developer I rarely had to work at this level, but experience in OOD and in writing good maintainable code is meaningless for C++ interviews. Reading books as a refresh and looking at sample code did not do the trick. I also looked at mid-to-senior level Java positions, but most of them focused on J2EE APIs rather than on core Java and required a certain number of years in industrial positions. Coding research tools and prior C++ experience doesn't count. So that sends me back to entry-level jobs that are posted through job-boards, and these are not common (mostly they are Monster junk), and small companies are even less likely to answer a Ph.D. compared to the giants who participate in top-10 career fairs. Even worse, in many companies initial screening is done by HR folks who really don't want to deal with anything anomalous like a Ph.D. Any tips on how I should approach this intractable position? For example, what should I write in cover letters? Note that while immigration is not an issue for me, I cannot go freelance as I need the benefits (and in particular group health insurance). During my studies I had no time to contribute to open-source projects or maintain a popular blog, so even if I invested in that now there would be no immediate benefit. Updates: In the two months after posting this I received several offers to work as a core Java developer in the financial industry and accepted one from a firm where I am working to this day. For those who find themselves in similar situations, here are my tips: Give up on trying to find an entry level positions. You can't undo time. Accept the fact that there is Ph.D. discrimination in the job market (some might say rightfully so). It is legal to discriminate based on education. No point fighting it. The most important tip is to focus on the language you are comfortable with. The sad truth about programming in a particular language is that it is not like riding a bike. If you haven't used a language in the last few years, and can't actually apply it routinely (not just as a refresher) before you start your search, it is going to be very difficult to do well in an interview. Now that I'm interviewing others, I routinely see it in folks with a mixed C++/Java background. We maintain "a shadow" of the old language but end up with a weird mix that makes it hard to interview on either. Entry-level folks are at an advantage here since they usually have one language. Memory can help you do great in a screening interview, but without recent day-to-day experience, code tests will be difficult. Despite the supposed relation, core Java programming and J2EE programming are two different things with different skillsets. If you come from academia, you likely have very little J2EE experience and may find it hard to get accepted for a J2EE job. J2EE jobs seem to have a larger list of acronyms in their requirements. In addition, from interviewing J2EE developers it seems that for many there is a focus on mastering specific APIs and architectures, whereas core Java development tends to be secondary. In the same way that I can no longer manipulate pointers well, a J2EE developer may have difficulties doing low level Java manipulation. This puts you at a relative advantage in competing for core Java jobs! If you are able to work for startups (in terms of family life and stability) or migrate to startup-rich areas such as the west coast, you can find many exciting opportunities where advanced degrees are a benefit. I've since been approached by several startups, although I had to decline. Work through a recruiter if possible. They have direct contacts with the hiring parties, allowing you to "stand out". It is better to get a clear yes/no confirmation from a recruiter on whether a company might be interested in interviewing you, than it is to send your resume and hope that someone will ever see it. Recruiters are also a great way of bypassing HR. However, also beware of recruiters. They have a vested interest and will go to various shady practices and pressure tactics. To find a good recruiter, talk to a friend who declined a job offer he got through a recruiter. A good recruiter, to me, is measured in how they handle that. Interview for the jobs that require your core strength. If you're rusty or entirely unfamiliar with a technology around which the job revolves, you're probably not a good match. Yes, you probably have the talent to master them, but most companies would want "instant gratification". I got my offers from companies that wanted core Java developer. I didn't do well on places that wanted advance C++ because I am too rusty and not up to date on recent libraries. I also didn't hear from companies that wanted lots of J2EE experience, and that's ok. Finding companies that want core Java without web is harder, but exists in specific industries (e.g., finance, defense). This requires a lot more legwork in terms of search, but these jobs do exist. There are different interview styles. Some companies focus on puzzles, some companies focus on algorithms, and some companies focus on design and coding skills. I had the most success in places where the questions were the most related to the function I would have been performing. Pick companies accordingly as well.
