  • What are best practices for testing programs with stochastic behavior?

    - by John Doucette
    Doing R&D work, I often find myself writing programs that have some large degree of randomness in their behavior. For example, when I work in Genetic Programming, I often write programs that generate and execute arbitrary random source code. A problem with testing such code is that bugs are often intermittent and can be very hard to reproduce. This goes beyond just setting a random seed to the same value and starting execution over. For instance, code might read a message from the kernal ring buffer, and then make conditional jumps on the message contents. Naturally, the ring buffer's state will have changed when one later attempts to reproduce the issue. Even though this behavior is a feature it can trigger other code in unexpected ways, and thus often reveals bugs that unit tests (or human testers) don't find. Are there established best practices for testing systems of this sort? If so, some references would be very helpful. If not, any other suggestions are welcome!

  • My Hard Disk Drive is not visible until I use it

    - by Matthew
    So, suddenly something went wrong. At the beggining of my Ubuntu usage it was all right, but from about 2-4 weeks I've got this problem: Whenever I try to reach my HDD, i have to open it first by files explorer. Example: I use text editor. Last file fails to load, so I got to open it manually. It's in bookmarked file. I want to reach my bookmark, which is on HDD(partition for both Ubuntu and Windows , NTFS). If i want to reach my bookmark, i have to go there manually(or at least to HDD, then bookmarks pops up). It also doesn't appear at my side bar until i use it. It kinda looks like it wasn't mounted till then, I don't know. It would be nice if I could deal with it, let's say, automatically. Thanks in advance.

  • How to speed up rsync/tar of large Maildir

    - by psusi
    I have a very large Maildir I am copying to a new machine ( over 100 BaseT ) with rsync. The progress is slow. VERY SLOW. Like 1 MB/s slow. I think this is because it is a lot of small files that are being read in an order that essentially is random with respect to where the blocks are stored on disk, causing a massive seek storm. I get similar results when trying to tar the directory. Is there a way to get rsync/tar to read in disk block order, or otherwise overcome this problem?

  • SQL Server Compressed Backups Disk Space Needs

    SQL Server 2008 and later offers the ability to create compressed backup files. When creating the compressed backup, how much space is really needed and when does the space get allocated for the backup file?

  • Is there a difference between multi-tasking and time-sharing?

    - by Dummy Derp
    Just going over my school notes, my teacher identifies multi-tasking OS, and time-sharing OS as two different things. I really don't see a difference between the two. MULTI-TASKING: You load a number of programs in the memory and execute them. You execute another program if the time quantum allocated to the current program expires OR if it goes on to do I/O and leaves the CPU OR if it finishes execution. TIME-SHARING: the same,again. The same applies in case of serial processing and batch processing. Although they are the same, I guess the only difference would be the way in which control information is passed to the CPU. Maybe, and again MAYBE, in serial processing you need to provide the punch cards with all the processes while in batch, the entire batch uses the same set of control information. Like all the print jobs would have the same control information.

  • POSH-y SQL Disk Space Monitoring

    - by merrillaldrich
    In a prior post I expressed my dismay that apparently Operations Manager (which I dig in other respects) has no love for SQL Server storage that uses mount points. Herewith, henceforth, forthwith is a PowerShell workaround I am using until I find out I am wrong, or there’s a management pack fix. The crux of the issue, I think, is that SQL Server itself has basically no visibility to the disks mounted using mount points, and that blind spot carries through to the management pack. That much is well...(read more)

  • Programs keep waiting for external disk to spin up - how to ignore disk?

    - by Andrew J. Brehm
    Like many Mac users I have an external Firewire disk hooked up to my Mac to be used by Time Machine. This works very well, backup-wise. The problem is that very often when I use a Mac application and try to open a file, the file selection dialogue window hangs until the external disk has spun up. I never ever want to open a file on the external disk. Sometimes this happens even when I just want to save a file I already saved (i.e. type something and press meta-s). Is there anything I can do about this?

  • Options for connecting an external disk to an old laptop

    - by agnul
    I've tried connecting a 2.5" external drive to an old laptop which has only USB 1. The LED on the disk lights up, but the disk doesn't seem to spin up. Since the same disk works fine on a newer laptop my guess is that the old one doesn't output enough power on the USB port. Besides looking for an external drive with its own PSU, what would you suggest? Will one of those USB cables with two connectors work? What about a powered USB hub?

  • How did we get saddled with the (hierarchical) filesystem as the basic data structure?

    - by user1936
    I'm self-taught and I don't have a CS degree. The more I've been learning about data structure, the more I wonder, in this day and age, how are we still saddled with the filesystem, with directories and files, as the basic data storage structure on the OS? I understand the simplicity of it, but it seems nowadays that there could be more options available natively. As far as I'm aware, the only project to improve the basic functionality of the filesystem was ReiserFS, where you could tell what line of a file was changed by whom, and when. For instance, if I could have native tagging for files, where I could tag images, diagrams, word-processing documents, an entire code repository, all as belonging to a single project, that would really be helpful to me. Since I'm stuck in the filesystem paradigm, I know that I could put all those into a single folder/directory, but what if they already exist in disparate directories, and they need to stay there? I know there are programs out there that can do this, but why aren't they on the filesystem? Something that would be nice to have is some kind of relational feature in the filesystem, like you get with RDBMSes. I understand that that was supposed to be part of Vista/7, but that fell off the feature list too. Sure, any program can store a binary file and have any data structure it wants in it, by why couldn't the OS offer more complex ways of storing data, beyond the simple heirarchy of the filesystem?

  • Why was Tanenbaum wrong in the Tanenbaum-Torvalds debates?

    - by Robz
    I was recently assigned reading from the Tanenbaum-Torvalds debates in my OS class. In the debates, Tanenbaum makes some predictions: Microkernels are the future x86 will die out and RISC architectures will dominate the market (5 years from then) everyone will be running a free GNU OS I was a one year old when the debates happened, so I lack historical intuition. Why have these predictions not panned out? It seems to me, that from Tanenbaum's perspective, they're pretty reasonable predictions of the future. What happened so that they didn't come to pass?

  • Creating Ubuntu bootable disk on my phone

    - by Aerus
    I want to install Ubuntu 12.04 on my laptop but because I have a complete shortage of writable CDs and DVDs, I wan't to create a bootable USB stick (on Windows). However, the only USB stick I currently have lying around is my HTC phone (HTC Touch HD with 8Gb memory). I was following the Ubuntu guide to create a bootable usb stick with pendrivelinux, however in the last step it shows me that it wants to do more than just copying the .iso file to the USB drive: My question: can I safely proceed without wiping the current OS off my phone (Windows Mobile 6.1) and use it to install Ubuntu?

  • Upgrading a dual-boot system HDD

    - by Jason
    I dual-boot my laptop due to lousy VM performance, and have a new 500GB/7200rpm drive coming in to replace the stock 320GB/5400rpm drive. I have the drive set up in three partitions: one for the Win7 system files, one for storage, and the third as the ext4 Linux file system. The system file and storage partitions are both NTFS. What I'm planning to do is use the system image creator built in Win7, then move that over to the new drive. However, how can I migrate the Ubuntu partition, and how do I make sure that the Grub bootloader isn't overwritten by the Windows loader?

  • Is it reasonable to make a RAID-1 array with a ram disk and a physical disk to maximize read performance and protect data?

    - by Petr Pudlák
    In one of the answers on SO (I forgot which one) I've seen a suggestion to make a RAID-1 array composed of a RAM disk and a physical partition. By adding the physical partition with --write-mostly and enabling --write-behind the system should read everything instantly from the RAM disk but still save all data to the physical partition so that the data are preserved and the RAID array can be assembled again after reboot. Is such a setup reasonable? Will it perform any better in some scenario than having just the physical partition and perhaps tweaking the kernel to favor disk cache (swappiness and vfs_cache_pressure)?

  • Resize a 2TB partition on a 3TB disk created with fdisk

    - by mR_fr0g
    I recently added a new 3TB hard drive to a headless media server (HP proliant microserver) running Ubuntu server 12.04. I followed this tutorial, which uses fdisk to create a single partition of the maximum size reported by fdisk. I have choosen ext4 format. I then copied across all my media, which took some time. I am guessing that fidisk has a 2TB limit, because du is reporting this as the size. Is there any way to increase the size of the partition to 3TB without having to copy all my media over again?

  • How to extend a partition in Windows 2000 Server

    - by user999684
    I have a Windows 2000 Server set up with RAID 5. I initially defined 2 136 GB logical disks 0 and 1. I have a small utility partition on disk 0 along with the C drive. I wish to extend the C drive to use disk 1 as well, which is now configured to drive D. I deleted drive D, but it is still in disk 1. I download partdisk.exe from MS, but am not sure how to accomplish what I want to do. I know I need to use extend, but I think I need to remove disk 1 and somehow add the unallocated space to disk zero, but am not at all confident on how to do it.

  • User management system and DELETE action - usability

    - by šljaker
    I'm working on User Management System in ASP.NET MVC3. Administrator/Editor can search, insert, update and delete other users from the system. What should I do when admin/editor clicks on Delete user link? Should I redirect him to new yes/no confirmation page or display some jquery popup window? Should I then redirect him to the home page and display message 'The user has been successfully deleted from the system', or simple redirection should be just fine?
