• Sorting 1 million 8-digit numbers in 1MB of RAM

  - by Favourite Chigozie Onwuemene

  I have a computer with 1M of RAM and no other local storage. I must use it to accept 1 million 8-digit decimal numbers over a TCP connection, sort them, and then send the sorted list out over another TCP connection. The list of numbers may contain duplicates, which I must not discard. The code will be placed in ROM, so I need not subtract the size of my code from the 1M. I already have code to drive the ethernet port and handle TCP/IP connections, and it requires 2k for its state data, including a 1k buffer via which the code will read and write data. Is there a solution to this problem?

• How can two programs talk to each other in Java?

  - by Arnon

  I want to ?reduce? the CPU usage/ROM usage/RAM usage - generally?, all system resources that my app uses - who doesn't? :) For this reason I want to split the preferences window from the rest of the application, and let the preferences window to run as ?independent? program. The preferences program ?should? write to a Property file(not a problem at all) and to send a "update signal" to the main program - which means it should call the update method (that i wrote) that found in the Main class. How can I call the update method in the Main program from the preferences program? To put it another way, is a way to build preferences window that take system resources just when the window appears? Is this approach - of separating programs and let them talk to each other (somehow) - the right approach for speeding up my programs?

• RealTek RTL8188CE WiFi adapter doesn't connect reliably

  - by ken.ganong

  I recently bought a new system76 laptop which came pre-installed with Ubuntu 11.10. I've been having trouble with my wireless connectivity.

• Create USB installer from the command line?

  - by j-g-faustus

  I'm trying to create a bootable USB image to install Ubuntu on a new computer. I have done this before following the "create USB drive" instructions for Ubuntu desktop, but I don't have an Ubuntu desktop available. How can I do the same using only the command line? Things I've tried: Create bootable USB on Mac OS X following the ubuntu.com "create USB drive" instructions for Mac: Doesn't boot. usb-creator: According to apt-cache search usb-creator and Wikipedia usb-creator only exists as a graphical tool. "Create manually" instructions at help.ubuntu.com: None of the files and directories described (e.g. casper, filesystem.manifest, menu.lst) exist in the ISO image, and I don't know what has replaced them. unetbootin scripting: Requires X server (graphics support) to run, even when fully scripted. (The command sudo unetbootin lang=en method=diskimage isofile=~/ubuntu-10.10-server-amd64.iso installtype=USB targetdrive=/dev/sdg1 autoinstall=yes gives an error message unetbootin: cannot connect to X server.) Update Also tried GRUB fiddling: Merging information from pendrivelinux.com a related question on the Linux Stackexchange and a grub configuration example I was able to get halfway there - it booted from USB, displayed the grub menu and started the installation, but installation did not complete. For reference, this is the closest I got: sudo su # mount USB pen mount /dev/sd[X]1 /media/usb # install GRUB grub-install --force --no-floppy --root-directory=/media/usb /dev/sd[X] # copy ISO image to USB cp ~/ubuntu-10.10-server-amd64.iso /media/usb # mount ISO image, copy existing grub.cfg mount ~/ubuntu-10.10-server-amd64.iso /media/iso/ -o loop cp /media/iso/boot/grub/grub.cfg /media/usb/boot/grub/ I then edited /media/usb/boot/grub.cfg to add an .iso loopback, example grub entry: menuentry "Install Ubuntu Server" { set gfxpayload=keep loopback loop /ubuntu-10.10-server-amd64.iso linux (loop)/install/vmlinuz file=(loop)/preseed/ubuntu-server.seed iso-scan/filename=/ubuntu-10.10-server-amd64.iso quiet -- initrd (loop)/install/initrd.gz } When booting from USB, this would give me the Grub boot menu and start the installer, but the installer gave up after a couple of screens complaining that it couldn't find the CD-ROM drive. (Naturally, as the box I'm installing on doesn't have an optical drive.) I resolved this particular issue by giving up and doing the "create USB drive" routine using the Ubuntu Live desktop CD (on a computer that does have an optical drive), then the USB install works. But I expect that there is some way to do this from the command line of an Ubuntu system without X server and without an optical drive, so the question still stands. Does anyone know how?

• HighPoint RocketRAID 62x Controller

  - by TeXnewbie

  I have the subject card recently installed in Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-31-generic x86_64). See partial lspci -vv listing below (complete listing played havoc with pre tags): 03:00.0 RAID bus controller: HighPoint Technologies, Inc. Device 0622 (rev 01) Subsystem: HighPoint Technologies, Inc. Device 0001 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Latency: 0, Cache Line Size: 32 bytes Interrupt: pin A routed to IRQ 11 Region 0: I/O ports at 9c00 [size=8] Region 1: I/O ports at 9800 [size=4] Region 2: I/O ports at 9400 [size=8] Region 3: I/O ports at 9000 [size=4] Region 4: I/O ports at 8c00 [size=16] Region 5: Memory at fdbff000 (32-bit, non-prefetchable) [size=2K] Expansion ROM at fdbe0000 [disabled] [size=64K] Capabilities: I followed instructions I found at https://help.ubuntu.com/community/RocketRaid to compile the drivers for it, and although performing the process described there seemed to work fine with no noticeable errors, when I rebooted after performing that procedure I could not boot. During dkms steps, I noticed messages indicating that (If next boot fails, revert to initrd.img-3.2.0-31-generic.old-dkms image) update-initramfs................ so I booted using a Ubuntu 12.10 LiveDVD and reverted to the old-dkms initrd.img as suggested above, but this failed to repair the boot problem. Ultimately, I used https://help.ubuntu.com/community/Boot-Repair in Ubuntu-Secure-Remix to fix the boot problem and was able to boot normally again, but now with the newly generated initrd.img in place again (which now boots normally), when I modprobe the rr62x kernel module, I immediately get a hard crash with messages to console about a kernel paging request that seems to have caused the problem. I've tried on multiple occasions now to use the newly built kernel module so as to allow me to use an eSATA port multiplier plugged into the card, but to no avail. Any suggestions on fixes or workarounds (I've read that some of the HighPoint cards (2720SGL) seem to work as a host bus adapter and thus may not need a custom driver, but that seems not to be the case for mine) would be most appreciated. My goal is to use the card as described here and with software RAID mdadm utilities. If necessary, I can hand-copy the console messages after the hard crash into a follow-up message, but I obviously can't do a cut/paste. I'll gladly provide any other details that are needed, but not sure what those would be at this point, so I'll refrain from adding other details for now. Thanks in advance for any help.

• Correcting color-shifted mirrored i915 driver in 12.04?

  - by Will Martin

  I was called in to fix a friend's malfunctioning HP Pavilion. She's not sure exactly which model, but the sticker on the bottom says "G60". The problem was a failed upgrade to 12.04. I was able to mostly repair it with sudo apt-get -f install, which ran setup and configuration for several hundred packages. The biggest problem at the moment is Xorg. The login screen (lightdm) loads normally but at a reduced resolution (1024x768 instead of 1366x768). But once you log in, it looks like this: Observe that the colors of the dock on the left and the bar at the top are normal. But the background is filled with bizarro color-skewed ghost images of the desktop. In all cases, the actual contents of any programs you run is a totally illegible mess, except that the bar at the top of any program windows looks and acts normally. And the ghost images are interactive! For example, if you click the icon in the top right corner to get the "shut down" menu, the same menu will appear in the ghost images below. Starting a terminal will start a terminal window in both the real desktop and the ghost images, and moving it around updates both the real and ghost desktops. I suspect Xorg is using some kind of wrong driver and/or parameter for the graphics hardware. Here is the graphics-relevant portion of the lspci -v output: 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 09) Subsystem: Hewlett-Packard Company Device 360b Flags: bus master, fast devsel, latency 0 Capabilities: [e0] Vendor Specific Information: Len=0a <?> Kernel driver in use: agpgart-intel 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device 360b Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at d0000000 (64-bit, non-prefetchable) [size=4M] Memory at c0000000 (64-bit, prefetchable) [size=256M] I/O ports at 5110 [size=8] Expansion ROM at <unassigned> [disabled] Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [d0] Power Management version 3 Kernel driver in use: i915 Kernel modules: i915 00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) Subsystem: Hewlett-Packard Company Device 360b Flags: bus master, fast devsel, latency 0 Memory at d2500000 (64-bit, non-prefetchable) [size=1M] Capabilities: [d0] Power Management version 3 I'm not sure what to check next. I would ordinarily check xorg.conf to see what it says, but that apparently doesn't exist any more, and my googling has not yielded any useful techniques for getting Xorg to tell me what settings it decided to use. The weird part is that it works fine on the login screen. It's only when you actually log in as a user that the display gets screwed up. Suggestions?

• Second Monitor stays black/in power save mode

  - by Rob

  I'm using two Monitors, a Belinea o.display 1 (Recognized as a Rogen Tech Distribution Inc 20" by Ubuntu, but working fine) on the DVI-Output (connected via DVI-to-VGA-adapter) as my primary Monitor and a Dell 19" (Recognized correctly) on the HDMI-output (via HDMI-to-DVI adapter) as secondary monitor. The graphics controller is a GeForce 9500 GS. I'm running a fully updated Ubuntu 13.04 with nouveau 1:1.0.7-0ubuntu1. The problem is that the second monitor (Dell) never seems to come out of standby during boot: the screen stays black and the status led on the monitor stays orange (it's green when it's on). It is correctly recognized an the size of the desktop is set accordingly, it just stays black. Changing any setting via xrandr/arandr/etc. does nothing. The on-screen-menu of the monitor reports it to be in power save mode. When using the proprietary NVIDIA-Drivers, the second monitor works just find. But these drivers cause a lot of other problems on my system, so i would really like to avoid them. On Ubuntu 12.10 i had found a workaround: When moving the relative position of the second monitor slightly down and the up again, it would turn on and function normally: xrandr --output DVI-I-1 --mode 1680x1050 --pos 1280x0 --rotate normal --output HDMI-1 --mode 1280x1024 --pos 0x88 --rotate normal sleep 2 xrandr --output DVI-I-1 --mode 1680x1050 --pos 1280x0 --rotate normal --output HDMI-1 --mode 1280x1024 --pos 0x0 --rotate normal This workaround stop working after the update to 13.04, and now i'm looking for a new solution. Has anyone experienced something similarity? xrandr output: Screen 0: minimum 320 x 200, current 2960 x 1050, maximum 8192 x 8192 DVI-I-1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 433mm x 270mm 1680x1050 60.0*+ 1280x1024 75.0 60.0 1280x960 60.0 1152x864 75.0 1024x768 75.1 72.0 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 72.8 75.0 66.7 60.0 720x400 70.1 HDMI-1 connected 1280x1024+1680+0 (normal left inverted right x axis y axis) 376mm x 301mm 1280x1024 60.0*+ 75.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 lshw -c video: *-display Beschreibung: VGA compatible controller Produkt: G96 [GeForce 9500 GS] Hersteller: NVIDIA Corporation Physische ID: 0 Bus-Informationen: pci@0000:01:00.0 Version: a1 Breite: 64 bits Takt: 33MHz Fähigkeiten: pm msi pciexpress vga_controller bus_master cap_list rom Konfiguration: driver=nouveau latency=0 Ressourcen: irq:16 memory:fa000000-faffffff memory:d0000000-dfffffff memory:f8000000-f9ffffff ioport:df00(Größe=128) memory:fb000000-fb07ffff Thanks for your help!

• Can my machine run Ubuntu( kubuntu | xubuntu | mint ) 12.04 WELL?

  - by Steve

  I have a 9 year old computer packing the hardware listed below. My question is, can I run 12.04 ( Ubuntu, Kubuntu, MINT or Xubuntu ) WELL? I was running Ubuntu 10.10 and I upgraded to 12.04 by going through each release via the update manager: 11.04 - 11.10 -12.04 During the installation process for 12.04 I saw an error message that there was an error installing and setting up part of the kernel. Later, when I tried installing a package in synaptic, I got another error message mentioning the kernel. When I rebooted, I got told somehting about my video and graphics was not configured properly and that I would have to do it manually ( like I know ). It gave me the option to enter the system in low graphics mode, but it just hanged. I had an old livecd of Xubuntu 10.10 around so I used that to get into my computer and copy data over to an external hard drive. I think tried to install Xubuntu 10.10 from the livecd, with the option "download updates" checked. The install process moved along a bit, then halted for about 5 hours. I rebooted my machine and tried the Xubuntu 10.10 installer WITHOUT the option to "download updates". The install completed in about 15 minutes. So, all of that is making me wonder if there is someting about 12.04 that does not like my hardware. I'm willing to try again, but only if I know I will not have to spend hours just to get to an error message and a hosed up system like I did last night. I also think I have a lot more RAM than is being reported in the output below. I had extra ram installed last year. I'm not good with the command line readouts, but there seems like there should be a lot more. I wasn't thrilled with Unity. I am willing to try Kubuntu 12.04. Will I run into the same problems? What is the highest version of a *ubuntu can I upgrade to?

• Office 2007 Setup prompts for PptLR.cab

  - by kamleshrao

  While running Office 2007 Ultimate Setup on Windows 7 box, I get this error message - "Setup cannot find PowerPoint.en-us\PptLR.cab". This file is very much present in the setup folder. It gives me an option to choose the correct path of this file, but when I browse and navigate to the folder containing this file, it doesn't show me the CAB file for selection. I tried installing both from DVD and also running setup from hard disk location. The same setup media was used earlier for installation on Vista without any issues!

• Cannot reactivate RAID-5 volume: The size of the plex member is invalid

  - by Ian Boyd

  We had a 3-drive Windows Server 2008 R2 RAID-5 fail (operating in redundancy mode): WDC 1 TB WDC 1 TB WDC 1 TB We removed the failed hard drive, and put a WDC 1 TB drive (that we had standing by) into the machine. When launched, Disk Manager, asked permission to "initialize" the disk as either: Master Boot Record (MBR) Guid Partition Table (GPT) We initialized the disk as GPT, converted it to dynamic, and tried to use the Repair Volume command - except it was greyed out. (which is a terrifying thing on a failed production server hosting 3 virtual servers) i tried from the diskpart command line tool. First we look for our RAID-5 volume that is in Failed Rd mode: DISKPART> list volume Volume ### Ltr Label Fs Type Size Status Info ---------- --- ----------- ----- ---------- ------- --------- -------- Volume 0 E VMs (Raid5) NTFS RAID-5 1863 GB Failed Rd Volume 1 D DVD-ROM 0 B No Media Volume 2 System Rese NTFS Partition 100 MB Healthy System Volume 3 C NTFS Partition 1862 GB Healthy Boot There, Volume 0. Make that our active context: DISKPART> select volume 0 Volume 0 is the selected volume. Now we need to find the disk we will be repairing the volume with: DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ------------- ------- ------- --- --- Disk 0 Online 931 GB 0 B * Disk 1 Online 931 GB 931 GB * Disk 2 Online 1863 GB 0 B Disk 3 Online 931 GB 0 B * Disk M0 Missing 0 B 0 B * The disk with 931 GB free, Disk 1. Now we just need to repair the volume: DISKPART> repair disk=1 Virtual Disk Service error: The size of the plex member is invalid.

• Installing Win7 over PXE through Serva fails on Loading Network Resources

  - by Armand

  Trying to install Win7 OS to a Lenovo E335 with no DVD/CD. I have to do it either over PXE/Network or USB. Although I am able to get passt the installation menu of Serva, it fails on Loading Network Resources ... FAILED No NIC/Driver, ABORTING! This is the only log on the Serva Client PC and nothing on the Serva-server. Would appreciate if someone can tell me how to go pass this error. THe network card works fine, it has already loaded the Windows installation structure on a X: drive on the new laptop. Another detail: I am using a normal Ethernet Cable to connect the PCs. Should this be enough or a crossover cable is a must in this case?

• hp ProLiant DL380 G6 server error code: 347 of array controller

  - by alhaythum

  I have got a bran new hp ProLiant DL380 G6 server with embedded smart array P410i controller, I got 164 GB SATA drives and wanted to change them with 300 GB SATA drives before installation. Now, we replace the drives and begin the configuration with the hp DVD and begin; when we reach the point that we want to save the configurations, an error message appears: "The operation has failed with an unknown error, please restart the application and attempt the operation again" When using Rescan System, this error message appears: "Status Alerts - Smart Array P410i in Embedded Slot Warning Status Message Code Description 347 The cache for Smart Array P410i Embedded Slot is not configured" We return back to the 164 GB SATA drives and the message just keeps appearing again. Any help please.

• Hard disk with bad clusters

  - by Dan

  I have been trying to backup some files up to DVD recently, and the burn process failed saying the CRC check failed for certain files. I then tried to browse to these files in Windows explorer and my whole machine locks up and I have to reboot. I ran check disk without the '/F /R' arguments and it told me I had bad sectors. So I re-ran it with the arguments and check disk fails during the 'Chkdsk is verifying usn journal' stage with this error: Insufficient disk space to fix the usn journal $j data stream The hard disk is a 300GB Partition on a 400GB Disk, and there is 160GBs of free space on the partition. My os (Windows 7) is installed on the other partition and is running fine. Any idea how I fix this? or repair it enough to copy my files off it?

• Can the Dell PowerEdge T320 boot from a USB stick in hard drive emulation mode?

  - by Icydog

  I am trying to install FreeNAS on a Dell PowerEdge T320. I've followed the instructions here (http://doc.freenas.org/index.php/Burning_an_IMG_File) to write the .img file to four different USB sticks with dd if=FreeNAS-9.2.1.5-RELEASE-x64.img of=/dev/sde, but I can't boot off of any of them. When I try to boot, I get the following screen: F1 FreeBSD F2 FreeBSD F3 Drive 0 Then it auto-selects F1 and either prints # about once a second forever, or it sits with a blinking cursor doing nothing. Forum posts and the wiki page linked above say to set the USB boot emulation mode to hard disk (as opposed to auto or CD/DVD/floppy), and older Dell PowerEdge models including the T310 have this option in the BIOS settings, but I cannot find it on the T320 with the latest BIOS 2.1.2. I have even tried writing the USB image to a USB hard disk, but with the same lack of success. Has anyone been able to find this USB boot setting on a T320, or been able to boot FreeNAS/FreeBSD from USB in some other way on a T320?

• Cisco AnyConnect on IOS 12.4(20)T

  - by natacado

  There are plenty of tutorials on setting up AnyConnect on an ASA unit, and a handful of links noting that IOS 12.4(15) and later support AnyConnect, but I can't seem to find any good documentation about how to setup AnyConnect on IOS; most tutorials assume you only want a clientless VPN on IOS. the best I've found is this document on Cisco's site, but it's not working for me in practice - see below. This is all on a Cisco 881W: router#show version | include Version Cisco IOS Software, C880 Software (C880DATA-UNIVERSALK9-M), Version 12.4(20)T1, RELEASE SOFTWARE (fc3) ROM: System Bootstrap, Version 12.4(15r)XZ2, RELEASE SOFTWARE (fc1) The old SSL VPN Client seems to install just fine: router#show webvpn install status svc SSLVPN Package SSL-VPN-Client version installed: CISCO STC win2k+ 1.0.0 1,1,4,176 Thu 08/16/2007 12:37:00.43 However, when I install the AnyConnect client, after authenticating it hangs for a while during the self-update process, and stops with an error that the "AnyConnect package unavailable or corrupted." When I try to install the AnyConnect package on the router, I'm told that it's an invalid archive: router(config)#webvpn install svc flash:/webvpn/anyconnect-win-2.3.2016-k9.pkg SSLVPN Package SSL-VPN-Client (seq:2): installed Error: Invalid Archive Does anyone have a good sample on how to get the 2.x AnyConnect clients working with a Cisco device running IOS?

• NetBSD Networking

  - by Mike

  Hello, everyone! I have an old Toshiba Satellite 4015CDT, with Pentium II MMX, 32MB RAM, 4GB HDD. It also has one USB 1.0 port, parallel and serial ports, a 3.5" floppy drive and a CD-ROM drive (probably almost dead). I've installed NetBSD on this machine (full install) and now I want to connect it to the Internet. Although it has one PCMCIA modem card in it, it is obviously not an option. I've narrowed down my available options to the following: Connect a USB wireless adapter. I have a Realtek RTL8192 adapter, but although the system gives me the device's name (through dmesg) it fails to recognize it as a network adapter. Connect the laptop to another machine through a serial connection, so that the other machine will serve as a bridge to the Internet. Here is the page from the NetBSD documentation on serial connections. Unfortunately, I was not able to find anything on bridging there. I would very much appreciate your suggestions on the topic. Thanks in advance.
