  - by gökhan

  good night my project is about that Write a program that uses a loop to calculate the first 15 values of the Fibonacci number sequence and store them in an array, call it FibArr, of size 15 DWORDS. Fibonacci number sequence is described by the following formula: Fib(1) = 1, Fib(2) = 1, Fib(n) = Fib(n -1) + Fib(n - 2). Place each value in the EAX register and display it with a call DumpRegs statement.So I dont have an idea about this topic please help me thanks

• Ubuntu Linux -- create custom burnable/bootable DVD image?

  - by ashgromnies

  I recently developed some kiosk software that runs on Ubuntu Linux, and my client needs me to set up ten more computers with the complete software package(and that number will only grow in the future). So I'm looking for a way to make this less of a pain in the neck and prevent me from shooting myself in the foot -- I had to disable some things on the installations of the operating systems like screensavers, automatic updates, etc. that would pop up and disrupt the kiosk operation. I don't feel comfortable doing that by hand across 10 computers, it seems stupid. Does anybody have recommendations for software that would let me burn an installable DVD with a complete image of the hard drive from one of the devices? I've looked at Clonezilla, G4L, and PartImage and I'm still not quite sure if any of them offer what I need. I know PartImage for sure won't work, because it doesn't support Ext4.

• Control Parameters and DropDownList Text

  - by Bunch

  This is something that I rarely need to do, grab a DropDownList’s selected item’s text for use in a datasource’s ControlParameter. To allow for this use SelectedItem.Text instead of the more common SelectedValue for the PropertyName. <asp:ControlParameter ControlID="ddlStuff" Name="stuffName" Type="String" PropertyName="SelectedItem.Text" /> The reason for using this is for text comparison. On rare occasions you may need to check the text against a list where the SelectedValue just does not help. Technorati Tags: ASP.Net

• Domain controller policies having administrative issues with program installations

  - by russ

  I have an issue with our domain and policies where a user needs administrative rights to install a program and someone provides the credentials for the 'run as admin' or 'run as other user' it will always show an error: Cannot find specified file on the drive. So we cannot install programs for our employees. How I fix it is I add the user to administrators, force a policy update, have them reboot, run as administrator and install it that way. Then remove them after and update the policy. Another way was to right click the install file (.exe/.msi) and add the user and administrator as an owner with full control. Only works when we have the installation file. I have no idea how to fix this and I can't find a relevant thread or QA about this problem. I can only find users having issues on their home computers not on a domain. Any help and threads to read would be great!

• Vertically resize two windows at same time?

  - by Guy

  I love the new feature in Windows 7 where I can grab the title bar and "slam" a window against the right edge of the computer and it will size that window to the right half of the screen. I can then grab another window and do the same against the left side of the screen. Once I've done that I often find that one of those windows needs a bit more horizontal space and the other can do with less. So I grab the edge in the middle of each window and resize that window so I can most efficiently use my screen space. Problem is that I have to do this twice, once for each window. Is there a way to grab the inside vertical edge of both windows at the same time so that I can make one wider and the other smaller at the same time?

• How many hours of use before I need to clean a tape drive?

  - by codeape

  I do backups to a HP Ultrium 2 tape drive (HP StorageWorks Ultrium 448). The drive has a 'Clean' LED that supposedly will light up or blink when the drive needs to be cleaned. The drive has been in use since october 2005, and still the 'Clean' light has never been lit. The drive statistics are: Total hours in use: 1603 Total bytes written: 19.7 TB Total bytes read: 19.3 TB My question is: How many hours of use can I expect before I need to clean the drive? Edit: I have not encountered any errors using the drive. I do restore tests every two months, and every backup is verified. Edit 2: The user manual says: "HP StorageWorks Ultrium tape drives do not require regular cleaning. An Ultrium universal cleaning cartridge should only be used when the orange Clean LED is flashing." Update: It is now May 2010 (4.5 years of use), and the LED is still off, I have not cleaned, backups verify and regular restore tests are done.

• set chars to uppercase between parenthesis

  - by emzap79

  let's assume in vim I have following lines: all what (strong) people have to do is pushing (heavy) weights over (and over) again in order to gain muscles and I need to convert words inside parenthesis to uppercase, what is the most convenient way to do so? How do I tell vim it needs to select everything to the first (!) closing parenthesis? So far I came up with :%s/\s(.*)\s/\U&/g unfortunately this will uppercase everything between 'strong' and 'heavy' which is not what I want. Any chance to tell vim it should select the chars to the next closing bracket only? (sorry for the silly example, couldn't think of something more sophisticated... or at least vim related... huh)

• Web Content Filtering for Windows Clients

  - by djoyce

  I'm working with a small business to solve a bunch of problems. One is their Windows 7 POS registers need to have web access restricted to only three remote support sites, but the back office machine needs an unfiltered connection. I'd like something I can install and configure on the few registers to block all but those few sites. In a perfect world this would restrict the normal register user, but the admin user would not be filtered. Free is best, if it works, but a small fee would be alright too. Microsoft's Family Safety filter is close, but requires a Windows Live account, which isn't ideal, but may be alright. Anyone use this in a small business environment? I'd prefer something easily managed at the local machines. K9 Web Protection is interesting and I'm going to look into it more. Are there other options? Seems like someone would have made something simple like this as an open source project, but maybe not.

• Blank desktop after updates today, only unity2d works now [closed]

  - by NewUbuntuUser

  Possible Duplicate: Unity doesn't load, no Launcher, no Dash appears I have been using 12.04 (wubi) since a week now and this is my 1st exposure to linux. Everything was going on fine till now , but today as soon as I updated through the update manager , docky gave a message that compositing is required or something, and i got an error window which asked me to report the error and then the update manager asked me to reboot. After rebooting , i just get a blank desktop screen , no launcher, no toolbar. I have to restart with the power key. However if i login through Unity 2d everything is fine except the benefits of the 3d environment. I guess something got messed up after the update and i cant figure out which program or file caused this mess. I would highly appreciate if someone could help me out with this as I really liked working on ubuntu after windows 7. Thanks! SOLVED-- Thanks @jrg for the link provided.. it helped me to come out of this mess. Actually some update of compizconfig made the unity plugin inactive did something to the Animation add ons , the one which you use for the burn effect etc. What i did was : On the blank desktop Pressed keys Ctrl + Alt + T to bring up the terminal and typed ccsm This brought up the compiz config system manager, there i enabled the unity plugin and rebooted. Everything started working fine. But then again when i started the addons plugin ,everything went back to square one.. :( . This time pressing Ctrl + Alt + T also did not help. Then i tried Ctrl + Alt + F1 , it brought up a terminal or whatever u call it, and then i typed unity --reset , it did some resetting and in the end it showed some comositing done , I pressed Ctrl + Alt + F7 to come back to the desktop , and here it was , my old sweet desktop.. it had the animation effects too like wobbly windows, excepting the addons like the burn effect, i guess something got wrong with the last update of that addon plugin and now whenever i try turning that on , everything goes poof!! 6 hours wasted , but i guess i learnt something new.. not bad for an orthodontist i guess :))

• Odd behavior of permissions and icons

  - by Urban

  After some virus had infected my Windows 7, I did a complete format and re-installed the OS. I was just installing applications and copying back some data when I noticed some shortcuts changing their icons to something I couldnt recognize (Yellow icons in the image below). Also, a few exe files which previously did not ask for User permission, are now asking for it. Wondering if this is an icon cache problem, I cleared the cache by deleting the IconCache.db in AppData/Local but the problem still persists. Although I did a full system scan with MS Security Essentials, I'm not sure if this is another virus or some other problem. I would appreciate any suggestions you might have. Edit: Now even Firefox needs permissions to launch. It's icon hasnt changed, but it's got the 'shield' overlay on it like the other yellow icons.

• multi-thread in mmorpg server

  - by jean

  For MMORPG, there is a tick function to update every object's state in a map. The function was triggered by a timer in fixed interval. So each map's update can be dispatch to different thread. At other side, server handle player incoming package have its own threads also: I/O threads. Generally, the handler of the corresponding incoming package run in I/O threads. So there is a problem: thread synchronization. I have consider two methods: Synchronize with mutex. I/O thread lock a mutex before execute handler function and map thread lock same mutex before it execute map's update. Execute all handler functions in map's thread, I/O thread only queue the incoming handler and let map thread to pop the queue then call handler function. These two have a disadvantage: delay. For method 1, if the map's tick function is running, then all clients' request need to waiting the lock release. For method 2, if map's tick function is running, all clients' request need to waiting for next tick to be handle. Of course, there is another method: add lock to functions that use data which will be accessed both in I/O thread & map thread. But this is hard to maintain and easy to goes incorrect. It needs carefully check all variables whether or not accessed by both two kinds thread. My problem is: is there better way to do this? Notice that I said map is logic concept means no interactions can happen between two map except transport. I/O thread means thread in 3rd part network lib which used to handle client request.

• MySQL - complete server migration (Ubuntu) [closed]

  - by Mr A

  Possible Duplicate: How to copy and move mysql database Dump all databases with SSH access I'm setting up a new dev machine, and I have the old one sitting right next to me. I'd like to do an exact copy of all MySQL structures and data from the old machine to the new. Nothing fancy needs to happen (it's a dev machine). No replication. I don't care about "downtimes" etc. Is there a super simple way to do this? For example, I have SSH on the old server, can I just use Nautilus, do a connect to server, and then transfer a folder over, replacing another folder with it and be done? It's the same version of MySQL on both sides. Same version of Ubuntu. Same in most respects.

• PC3200 RAM in Older Computer?

  - by skaz

  Hello all, I am inheriting a Dell Dimension 8200, but it needs RAM to get up and running. I have PC3200 sticks lying around, but I am not sure how to go about figuring out if the RAM is compatible, as RAM has always confused me. Here is the Dell Dimension 8200 Tech Specs: http://support.dell.com/support/edocs/systems/dim8200/specs.htm For RAM, it says: Memory type PC800 (non-ECC) I don't know if that is just the kind that comes with it, and I can put in PC3200 (I think, if it worked, this would run at the lower rating? Is that true?), or if that means only PC800 is compatible. Any help would be appreciated.

• Restart an in-use NFS server without interruption (within timeout)

  - by zebediah49

  I have a bunch of compute clients working on jobs, saving output data to a NAS machine. All machines are centos 6.2. They mount it via automount NFS, with a timeout of 1200 (default config). The NAS machine needs to be restarted. If I can restart the machine within that 1200s (20 minute) window, will the clients just block on IO until it comes back up? A minor interruption (pause) in service is ok, as long as it doesn't cause the running processes to error out. If necessary I could loop through and SIGSTOP all job processes, restart and resume them -- I just don't want to break the open file handles. How can I run a restart like this without killing processes with open files?

• RAID10 Without BBU, With UPS

  - by Richard

  My datacenter says that each rack has primary and backup power on each rack. I assume this means there is a UPS for each server. Therefore, do I have any need of getting a BBU for the following setup? Intel Cherry 520 SSD x 4 RAID 10 LSI-9260 with WRITEBACK CACHE ENABLED I have heard that without a BBU the data in the cache could be lost. Since my needs aren't mission-critical, I can afford to lose some data. But would the rest of the data on the HD be corrupted?

• If you had to teach professional development to students that just graduated school, what would be the topics?

  - by user2567

  The idea is to give them more chances to be efficient in a professional environment. Most students are good with theory, most of them are smart, but they have to learn how to solve common technical problems. They will be better programmers as they practice, but maybe we can help them with some introduction training. Which topics you would select for a two weeks full time training? It's an open question, I don't want to suggest things that will reduce the answers to a particular field.

• How to get the Host value inside ~/.ssh/config

  - by iconoclast

  Within a ~/.ssh/config or ssh_config file, %h will give you the HostName value, but how do you get the Host ("alias") value? Why would I want to do that? Well, here's an example Host some_host_alias HostName 1.2.3.4 User my_user_name PasswordAuthentication no IdentityFile ~/.ssh/some_host_alias.rsa.id LocalCommand some_script.sh %h # <---- this is the critical line If I pass %h to the script, then it uses 1.2.3.4, which fails to give it all the options it needs to connect to that machine. I need to pass some_host_alias, but I can't find the % variable for that. (And: yes! I'm aware of the risk of recursion. That's solved inside the script.) UPDATE: Kenster pointed out that I could just hard-code the Host value as an argument to the script. Of course this will work in the example I gave, but it won't work if I'm using pattern matching for the Host.

  Question: I need to auto-start a GUI application that requires sudo. I know I need to edit the sudoers file with: sudo visudo However, I don't know what to write in the file. What I already tried: sudo visudo and then added the following: nanostuff ALL = NOPASSWD: /usr/lib/AirVPN/AirVPN.exe I also tried with: nanostuff ALL = NOPASSWD /usr/bin/X11/airvpn and nanostuff ALL = NOPASSWD /usr/bin/airvpn None of those worked.
