  • Recommended book on Actors concurrency model (patterns, pitfalls, etc.)?

    - by Larry OBrien
    The Actors concurrency model is clearly gaining favor. Is there a good book that presents the patterns and pitfalls of the model? I am thinking about something that would discuss, for instance, the problems of consistency and correctness in the context of hundreds or thousands of independent Actors. It would be okay if it were associated with a specific language (erlang, I would imagine, since that seems universally regarded as the proven implementation of Actors), but I am hoping for something more than an introductory chapter or two. (FWIW, I'm actually most interested in Actors as they are implemented in Scala.)

  • Recommended storage scheme for home server? (LVM/JBOD/RAID 5...)

    - by j-g-faustus
    Are there any guidelines for which storage scheme(s) makes most sense for a multiple-disk home server? I am assuming a separate boot/OS disk (so bootability is not a concern, this is for data storage only) and 4-6 storage disks of 1-2 TB each, for a total storage capacity in the range 4-12 TB. The file system is ext4, I expect there will be only one big partition spanning all disks. As far as I can tell, the alternatives are individual disks pros: works with any combination of disk sizes; losing a disk loses only the data on that disk; no need for volume management. cons: data management is clumsy when logical units (like a "movies" folder) are larger than the capacity of any single drive. JBOD span pros: can merge disks of any size. cons: losing a disk loses all data on all disks LVM pros: can merge disks of any size; relatively simple to add and remove disks. cons: losing a disk loses all data on all disks RAID 0 pros: speed cons: losing one drive loses all data; disks must be same size RAID 5 pros: data survives losing one disk cons: gives up one disk worth of capacity; disks must be same size RAID 6 pros: data survives losing two disks cons: gives up two disks worth of capacity; disks must be same size I'm primarily considering either LVM or JBOD span simply because it will let me reuse older, smaller-capacity disks when I upgrade the system. The runner-up is RAID 0 for speed. I'm planning on having full backups to a separate system, so I expect the extra redundancy from RAID levels 5 or 6 won't be important. Is this a fair representation of the alternatives? Are there other considerations or alternatives I have missed? And what would you recommend?

  • Is it recommended to use more than one language at a startup?

    - by GoofyBall
    I work for a mobile startup where, for historical reasons, our chosen language was C#. I was recently assigned to a small project to build a tool that would be used by us internally. When I explained my intention to use Python to build this tool I was heavily criticized for this because introducing new languages, and technologies (Debian, Apache, Python and Django) into our ecosystem would make it harder for other developers to maintain (because only two other people know more than one language besides C#). I countered that this project would take far longer to develop in C# (which I think is an inherent problem with the language/.NET framework) and that the project was small and designed to solve a very particular problem. Of course it is necessary that the ecosystem be as a homogeneous as possible but if your are developing tooling, infrastructure, and internal systems when there are better things to build them with than C# then you should consider using them. By using one language you exclude a lot of other great libraries and frameworks out there, and this case it was the difference between taking one week to build in Python as opposed to a month in C#. Do you think it is acceptable to understand and use only only one language at a startup or even a larger company? Am I perhaps being naive??

  • Bluescreen after Ubuntu 12.10 installation, after recommended boot repair "no filesystem found" please help!

    - by Phil
    After I tried to install Ubuntu 12.10 into my Windows 7 a black screen came up and nothing happened for over five minutes. So I force shutdown my computer and started again on the linux CD. I partitioned the Linux partitions manually and installed Ubuntu. At the next reboot I got a bluescreen from Windows three secounds after loading. I tried to repair the problem by using boot-repair. Then I got out the url: http://paste.ubuntu.com/1430803 And after the next restart he told me that he didn't found the filesystem. Because he didn't found the filesystem it was unable to repair it with the windows CD. Then I tried to repair it with TestDisk and was able to change the Windows Partition into NTFS, but I was not able to repair the windows 7 boot partition. Now I get the message that No Bootloader is found when I restart. Please help me.

  • Is it recommended to apply the new said-great 200 line Linux kernel path to Ubuntu?

    - by takpar
    Hi, Nowadays I'm hearing a lot about the new ~200 line path to Linux kernel that is said makes sensible difference in performance. Now, do anyone has experience on applying this path on his Ubuntu kernel? I also saw an alternative way that claimed has a better result: wget http://launchpadlibrarian.net/59511828/cgroup_patch chmod +x cgroup_patch sudo ./cgroup_patch What do you think this is? Is this validated? I ask this question because I need more performance but I can't risk on stability.

  • What Interface Toolkit is being recommended for Ubuntu on Nexus7/Mobile Devices?

    - by Baggers
    I understand this is a may be a very premature question given that the current build is for testing Ubuntu Core, but I have just bought a Nexus7 to join in with this Ubuntu on mobile adventure and can't help wanting to start writing some apps! I haven't really dabbled with either GTK or QT for touch apps yet and, having seen that Ubuntu TV is using Nux, I wondered what people on AskUbuntu-land would recommend. Hope someone out there know this! Cheers

  • What is the recommended way to empty a SSD?

    - by Lekensteyn
    I've just received my new SSD since the old one died. This Intel 320 SSD supports TRIM. For testing purposes, my dealer put malware, err, Windows on it. I want to get rid of it and install Kubuntu on it. It does not have to be a "secure wipe", I just need the empty the disk in the mosy healthy way. I believe that dd if=/dev/zero of=/dev/sda just fills the blocks with zeroes and thereby taking another write (correct me if I'm wrong). I've seen the answer How to enable TRIM, but it looks like it's suited for clearing empty blocks, not wiping the disk. hdparm seems to be the program to do it, but I'm not sure if it clears the disk OR cleans empty blocks. From its manual page: --trim-sector-ranges For Solid State Drives (SSDs). EXCEPTIONALLY DANGEROUS. DO NOT USE THIS OPTION!! Tells the drive firmware to discard unneeded data sectors, destroying any data that may have been present within them. This makes those sectors available for immediate use by the firmware's garbage collection mechanism, to improve scheduling for wear-leveling of the flash media. This option expects one or more sector range pairs immediately after the option: an LBA starting address, a colon, and a sector count, with no intervening spaces. EXCEPTIONALLY DANGEROUS. DO NOT USE THIS OPTION!! E.g. hdparm --trim-sector-ranges 1000:4 7894:16 /dev/sdz How can I make all blocks appear as empty using TRIM?

  • Recommended Linux distro to boot into RAM (from USB flash drive)?

    - by user91583
    I don't mind if I use USB flash drive or CD-ROM, but I would prefer USB flash drive. I had a squizz at http://en.wikipedia.org/wiki/List_of_Linux_distributions_that_run_from_RAM On my own computer, I would be able to use any of the distros in the list. The largest "RAM required" in the list is 4GB. I would like to be able to use it on any computer, so I suppose 1GB or less would be better. I tried to follow the method described on Distro that I can load into RAM? but the distro listed there, from Israel Remix Team, doesn't seem to be available. Before I start trial-and-error on different distros, does anyone have any recommendations?

  • Is there a recommended way to use the Observer pattern in MVP using GWT?

    - by Tomislav Nakic-Alfirevic
    I am thinking about implementing a user interface according to the MVP pattern using GWT, but have doubts about how to proceed. These are (some of) my goals: - the presenter knows nothing about the UI technology (i.e. uses nothing from com.google.*) - the view knows nothing about the model or the presenter - the model knows nothing of the view or the presenter (...obviously) I would place an interface between the view and the presenter and use the Observer pattern to decouple the two: the view generates events and the presenter gets notified. What confuses me is that java.util.Observer and java.util.Observable are not supported in GWT. This suggests that what I'm doing is not the recommended way to do it, as far as GWT is concerned, which leads me to my questions: what is the recommended way to implement MVP using GWT, specifically with the above goals in mind? How would you do it?

  • What is the recommended way to package perl scripts for CPAN (and CorporatePAN)?

    - by szabgab
    Recently I looked at a module on CPAN that comes with a script to be installed which made me wonder. What is the recommended way to include a script in a package that should end up on the public CPAN and if there is any different recommendation for packages that would be released on an in-house CPAN server? The script starts like this: #!/usr/bin/perl eval 'exec /usr/bin/perl -S $0 ${1+"$@"}' if 0; # not running under some shell Two questions Do I understand correctly the eval part is unnecessary? That will be embedded by the CPAN client during installation and it will be very different when installing on Windows. What is the recommended sh-bang line? Would that be #!/usr/bin/env perl instead of the above?

  • Recommended apps for securing/protecting a new desktop machine install?

    - by Eddie Parker
    I'm hoping to harness the collective tips of superuser to gather recommended apps/configurations to keep a new desktop clean, virus free, and hopefully lower software rot. I ask because I've recently come across tools like dropbox, deepfreeze, returnil, etc, and I'm curious what other ones are out there to protect a new box. I personally am interested in Windows, but feel free to comment on whatever OS you'd like, freeware or otherwise. Ideally specify the OS in your answer(s). One answer per program please. Then, rather than duplicate posts, vote for the program if it is already listed. UPDATE: It's been noted that there are other questions similar to this one [1], so I'd ask that these answers focus on security and protection. [1] Related questions: http://superuser.com/questions/1241/what-are-some-must-have-windows-programs http://superuser.com/questions/1191/what-are-some-must-have-mac-os-x-programs http://superuser.com/questions/1430/must-have-linux-software http://superuser.com/questions/3855/must-have-networking-security-tools

  • What is the recommended glusterFS configuration for a growing website?

    - by montana
    Hello, I have a website that is tracking towards 50 million hits per day average, and within the next 3 months should be over 100 million hits per day. We are trying to use GlusterFS v 3.0.0 (with latest patches as of 1-17-2010) Currently, we've just upgraded to a load balancer environment that has 3 physical hosts with 6 Xen-Server 5.5u1 VM's (2 on each host) to serve webpage traffic. Each machine has 6 Raid-6 local storage drives (7200RPM-SATA). The old machine we came from had 1 mirrored SAS 10k drive. We also set up glusterFS currently with 3 bricks, one on each host, and it is serving the 6 VM's as clients. In testing, everything seemed fine. However when we went to production, it seemed that there just wasn't enough I/O's available to serve traffic even upwards of 15mil hits. Weeks prior, our old server was able to handle traffic, maxed out, at 20mil. Is there any recommended configurations for such an application, or things to be aware of that isn't apparent with their documentation at gluster.org for a site our size?

  • 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!

  • Upgrade Centos 5 tot PHP 5.2 or 5.3 [recommended way?]

    - by solid
    We are using Zend Framework and in version 2, php 5.2 will be the minimum requirement. We love CentOS and we'd like to keep using it, but PHP 5.1 just won't do anymore when developing web applications with Zend framework. I found several links to solutions to upgrade with external repositories. http://serverfault.com/questions/106801/recommended-method-to-upgrade-php-5-1-6-to-5-2-x-on-centos-5 http://www.webtatic.com/blog/2009/05/installing-php-526-on-centos-5/ http://www.webtatic.com/blog/2009/06/php-530-on-centos-5/ We'd like to see another solution with the use of an "official?" CentOS repository if any is available. We only need to upgrade PHP, the rest of the CentOS setup is fine the way it is. For us, it's important however to keep the YUM cycle intact using the normal repositories. So in short: is it even possible to upgrade only PHP by using an external repo or otherwise? While still upgrading all our other packages safely through normal yum usage? Thanks for your help!
