  • How to input 64-bit hex values in octave

    - by Chris Ashton
    I'm trying to use Octave as a programmer's calculator. I want to input a 64-bit pointer, but when I do apparently the 64-bit value gets silently truncated to 32-bit: octave:44> base_ptr=0x1010101020202020 base_ptr = 538976288 octave:45> uint64(base_ptr) ans = 538976288 octave:46> printf("%lx\n", base_ptr) 20202020 So it seems like it's truncated the input value to the low 32-bits. I would use scanf, but the docs say it should only be used internally. How can I input the full 64-bit value? Alternately, is there some awesome free programmer's calculator out there for Windows? (I know Windows calculator has a programmer's mode but I would like arbitrary variable support). I tried using my ti-89 but it also doesn't support 64-bit hex.

  • Abysmal transfer speeds on gigabit network

    - by Vegard Larsen
    I am having trouble getting my Gigabit network to work properly between my desktop computer and my Windows Home Server. When copying files to my server (connected through my switch), I am seeing file transfer speeds of below 10MB/s, sometimes even below 1MB/s. The machine configurations are: Desktop Intel Core 2 Quad Q6600 Windows 7 Ultimate x64 2x WD Green 1TB drives in striped RAID 4GB RAM AB9 QuadGT motherboard Realtek RTL8810SC network adapter Windows Home Server AMD Athlon 64 X2 4GB RAM 6x WD Green 1,5TB drives in storage pool Gigabyte GA-MA78GM-S2H motherboard Realtek 8111C network adapter Switch dLink Green DGS-1008D 8-port Both machines report being connected at 1Gbps. The switch lights up with green lights for those two ports, indicating 1Gbps. When connecting the machines through the switch, I am seeing insanely low speeds from WHS to the desktop measured with iperf: 10Kbits/sec (WHS is running iperf -c, desktop is iperf -s). Using iperf the other way (WHS is iperf -s, desktop iperf -c) speeds are also bad (~20Mbits/sec). Connecting the machines directly with a patch cable, I see much higher speeds when connecting from desktop to WHS (~300 Mbits/sec), but still around 10Kbits/sec when connecting from WHS to the desktop. File transfer speeds are also much quicker (both directions). Log from desktop for iperf connection from WHS (through switch): C:\temp>iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 8.00 KByte (default) ------------------------------------------------------------ [248] local 192.168.1.32 port 5001 connected with 192.168.1.20 port 3227 [ ID] Interval Transfer Bandwidth [248] 0.0-18.5 sec 24.0 KBytes 10.6 Kbits/sec Log from desktop for iperf connection to WHS (through switch): C:\temp>iperf -c 192.168.1.20 ------------------------------------------------------------ Client connecting to 192.168.1.20, TCP port 5001 TCP window size: 8.00 KByte (default) ------------------------------------------------------------ [148] local 192.168.1.32 port 57012 connected with 192.168.1.20 port 5001 [ ID] Interval Transfer Bandwidth [148] 0.0-10.3 sec 28.5 MBytes 23.3 Mbits/sec What is going on here? Unfortunately I don't have any other gigabit-capable devices to try with.

  • Cannot find Power Management Tab in XP

    - by Andrew Heath
    I have the problem that when I send my computer to sleep it wakes if you bump the table, floor, burp etc. I have read many threads that say go to Device Manager Mouse Properties Power Management Tab and uncheck the box for wake. My problem is I do not have a Power Management Tab! Anyone know how to enable the tab or stop the mouse from waking my machine? And no, turning it upside down doesn't work either!

  • Can't find Role Services in Windows 7

    - by Pete Alvin
    I'm trying to install PHP on Windows 7 Home Premium using these instructions: Using FastCGI to Host PHP Applications on IIS 7 and a 1/3 of the way down on the page I have to do this: Server Manager -> Roles -> Add Role Services and just cannot find Roles or Role Services. Any ideas? PHP is giving me a 500 error and I'm wondering if it's because I haven't done this role services thing.

  • What steps put my bash prompt commands into vim and then back again to bash to execute?

    - by xtian
    I've enabled VIM style editing of bash commands at the bash prompt as default bash setting. On a few occasions I've accidentally opened a blank vim file with some complex bash command I was writing. Awesome. How do I get the newly written line in vim back into bash? I found another post where the author had the opposite trouble--or so it seems. What steps put my bash prompt commands into vim and then back again to bash to execute?

  • Forwarding emails from a domain

    - by Euwyn
    I generally use Google Apps to handle email domains. I'm unfortunately stuck in an infinite loop with Google [1] for one the domains I recently picked up. Right now I use Zerigo's awesome DNS services. How can I get [email protected] forwarded to my Gmail account? Better yet if this is a free/cheap solution and can work with multiple aliases going to different real email addresses ([email protected] - [email protected], [email protected] - [email protected]) [1] Long story. I alternate between "Sorry, you've reached a login page for a domain that isn't using Google Apps." and "This domain has already been registered with Google Apps." Seems like many others are having this issue and Google isn't doing anything about it.

  • Sharepoint Services 3.0: 403 Forbidden fun

    - by gravyface
    Can't get to the Administration or the "companyweb" site itself; was working up to a week ago. Old threads, blog posts, etc. indicate that there was an issue with a KB update but was resolved when .NET Framework 2.0 SP1 was deployed/installed. Running Process Monitor, I can see a lot of PATH NOT FOUND','NAME NOT FOUND for c:\inetpub\companyweb\Default.aspx, \_themes\ice\...\foo.css, etc. for the w3wp.exe process on CreateFileorQueryOpenoperations. These files do not exist in the location specified. I don't recall these files actually existing in that folder, but I believe they're "created" when requested, pulled in from Common Files/Shared or whatever, in typically-awesome Microsoft Web architecture land (</rant>). Besides reinstalling (which I'm sure will be as much fun as migrating from one server to another was), anyone know what's going on? Google-fu has alluded me.

  • Is there a way to unhook a global hotkey in windows?

    - by jonfuller
    I'm running Windows 7, and I installed an application that installed a global hot key (ctrl+shift+space) which conflicts with another application (Visual Studio) that uses that hotkey (though, not globally, only applications specific). The question is, knowing which application it is (ScanSnap Manager) and that it doesn't have a setting to turn off the hot key, is there a way I disable it through Windows somehow? Thanks!

  • Can't ping through default gateway

    - by Andrew G.H.
    I have the following configuration: Routing table on M3 is: Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 eth1 192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 192.168.3.0 0.0.0.0 255.255.255.192 U 0 0 0 eth0 Routing table on M1 is: Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 So basically M3's gateway is M1, and M1's gateway is M2's wireless internet interface. If I ping 8.8.8.8 from M1, everything is ok, replies are received. Pinging from M1 to M3 and viceversa is also possible. I have configured M1 as gateway trafic forwarder using firestarter package and stopped firewall with it. iptables policies are ACCEPT for everything. Problem: I have tried ping-ing ip 8.8.8.8 from M3 but without success. What could be the source of this problem?

  • Virtual box - How to add disks and move var, opt and home to them?

    - by Jarrod Roberson
    I created a CentOS 5.6 Guest OS Virtual Machine. I made the first disk 10GB, I am rapidly outgrowing it. It was suggested that I make disks for my /var, /opt and /home directories and move them so I can better manage the disks for backing up and what not. This sounds like a good idea. I know how to create the disks in Virtual Box. I have dug around Google and the internet in general and all my attempts at doing this have failed. Snapshots are awesome! I can get the drives fdisked, and I have had limited success mounting them to /mnt/var, /mnt/home and /mnt/opt, but even in single user mode ( init 1 ) I can't get the entire contents of the directories to move over, and then the machine won't reboot correctly. cd /var cp * -ax /mnt/var The /var directory in particular is not wanting to move everything to the new location. How do I format, mount and move the /var, /opt and /home to my new disks?

  • VirtuaWin shows Visual Studio 2010 in all Desktops

    - by w0lf
    I'm using VirtuaWin in Windows 7 to have virtual desktop functionality and I think this program is awesome. There's one small issue, though: on the computer at work, when moving to another desktop it hides all windows in the current desktop, except any windows of Visual Studio 2010. This means that VS 2010 shows up in all desktops, while for all other windows, VirtuaWin applies the correct behavior. The strange thing is that this issue happens on one computer only; on the others I have it works OK. I have checked the Window Rules section and nothing seems strange in there. Is anyone else experiencing this kind of problem? Any ideas on how to solve it?

  • Converting a Full HD Inspiron 9400 laptop LCD to a standalone monitor

    - by jhaukur
    Has anyone tried converting a LCD laptop monitor (17" full HD in this instance) to a stand-alone monitor? Are there any converters that one can buy to send DVI or VGA signals to the plug that is used to connect said LCD to the laptop motherboard? My laptop is the infamous Dell Inspiron 9400 (1705) model. They can have awesome monitors but if you check out ebay, there are many there for sale for little to nothing since the graphic cards fault unsually often in those machines. I'd like to be able to use the LCD and just scrap the rest.

  • Default Browser hangs (IE, Chrome)

    - by Craig Hinrichs
    IE was my default browser about three months ago when I started experiencing this issue. Intermittent hangs would occur when I would open a new main page or new tab to a site I know would be up. What I mean by a hang: The browser would open and say "Waiting for site " and do nothing more. If I closed the window and reopened it it would immediatly connect. Over time I would have to close and reopen the window to get to the page. This would happen to any page including Google. I finally got sick of it and started using chrome and I will never go back. I recently upgraded my anti-virus and now I am experiencing the same issue with Chrome. I use AVG for my antivirus. Empirically it seems if I don't make Chrome my default browser I don't experience the issue. I tested this theory for over two hours yesterday. Possible issues I have found this coudl be but not confirmed yet: MTU settings are not correct. I am infected but my antivirus has not caught it (unlikely but possible) ?? I would like to think this is related to my antivirus but I am unsure how to verify. I don't like the idea of killing my antivirus if #2 is a possibility. I am looking for tips on how I can trouble shoot possible issues. I am on Windows XP SP3 Thanks in advance.

  • Putty can't connect to USB modem on Windows 7

    - by IanM
    I'm trying to configure caller id on a USB modem connected to a Windows 7 x32 machine. Hyperterminal isn't available so I downloaded the latest version of Putty and am using the Serial option. I'm using the modem's COM port details from Device Manager (COM5, 115200 baud), but when I open the putty session it just hangs with the cursor at the top left hand corner. Hitting the Enter key does nothing. Any ideas??

  • "Safely remove hardware"...doesn't.

    - by Kev
    I have an external USB harddisk that I have scripted to safely shut down after a backup, so the backup operator can unplug it, and knows not to if the lights are still on for some reason. It's always worked fine using the DevEject command-line utility. This week it failed for some reason: DevEject 1.0 2003 c't/Matthias Withopf Ejecting 'USB Mass Storage Device' [USB\VID_0411&PID_002A\00000704C8D2]...FAILED (23,5) Error ejecting device USB Mass Storage Device, vetoed (15,5)! Worse yet, using the SRH tray icon, I click Stop, click OK, it pauses about 5 seconds with OK and Cancel greyed out, closes the sub-window, and then the main window with the Stop button still shows the device, and Stop is still available. I can keep doing that and it never gets rid of the device. I can still access it in Explorer. LockHunter reports that nothing is locking the drive. I've made no changes to the backup configuration or anything to do with the drive this week. Why the sudden flake-out? Short of a restart, which I can't do today before the backup operator goes home, how do I fix it?
