  • Which internet scenario would be better?

    - by JL
    I currently have an 8mbps (down) / 512kbps (up) telephone ADSL solution. I must say the reliability is excellent, and up until now its been the fastest connection I could get because I don't live in a cable zone. The real speed of my connection is around 7mbps, but sometimes I manage to get the full 8mbps. I use my connection for work, so it needs to be at least 99% reliable. Recently I was told by a guy who lives up the road that he has a wireless connection with an external antenna and his speeds are 20mbps / 512kbps - he's also paying about 1/2 of what I pay for my wired telephone connection. My question is, is wireless internet good enough for a power user who uses his connection for work 8 hours a day, including VPNing into servers remotely. Besides this I also enjoy playing the odd network game, not a WoW freak, but sometimes I do pick up the odd MMORPG and at times do indulge in some semi heavy gaming sprees. Will this wireless latency drive me crazy and seem slow in comparison? Will it be reliable enough, I also live in an area that snows heavily in winter. I guess its a question of - should I go wireless or not. I've only had 1 wireless connection before and that was years ago using iBurst technology and I remember it was terrible for VPN, but I guess the technology might have been improved since then? What do you guys think?

  • Can't do more than one activity at a time after switching modems

    - by vallorn
    I had to replace the Motorola 2210 DSL modem that I got when I signed up for AT&T DSL Direct a few years ago. The modem kept randomly restarting and it eventually gave out on me. I am assuming overheating was the cause here because it was almost too hot to touch. In any case, I replaced it with a Netgear DM111PSP. It works fine but I can't do more than one activity at a time with it. If my wife is watching Netflix, there is a noticeable delay/latency when trying to view web sites. It's even worse if I try to play an on-line game while she's streaming; the game is basically unplayable. The odd thing is, the only other activity I can do while she's streaming is stream another Netflix show myself. There is no delay when doing that, no buffering either. I'm not a networking guy so maybe there is an explanation for it but I find that kind of odd. I've tried using QoS through my Buffalo N600 wireless router and it doesn't seem to help. With the old Motorola modem, she could be watching Netflix while I play a game and everything worked just fine. Is there anything I can check or reconfigure possibly on the modem that would account for this? Should I just ditch the Netgear and get another modem instead? I have the Netgear modem connected to the Buffalo router in a bridged mode. Its the same exact setup as I had with the Motorola and as far as I can tell, it's not the router that is the cause.

  • What can I do to give some more love and disk space to my database on Ubuntu?

    - by Yaron Naveh
    I'm new to linux. I've deployed a db to ubuntu server on amazon and found out I'm low on disk space. did df (see below) - and found out that I'm 89% capacity on one file system, but less on others. What does this mean? Do I have a few partitions and can now utilize others besides /dev/xvda1? Also /dev/xvdb seems large, is it safe to put the db in it and only use it? If so do I need to mount it or do something special? $> df -lah Filesystem Size Used Avail Use% Mounted on /dev/xvda1 8.0G 6.7G 914M 89% / proc 0 0 0 - /proc sysfs 0 0 0 - /sys none 0 0 0 - /sys/fs/fuse/connections none 0 0 0 - /sys/kernel/debug none 0 0 0 - /sys/kernel/security udev 3.7G 8.0K 3.7G 1% /dev devpts 0 0 0 - /dev/pts tmpfs 1.5G 164K 1.5G 1% /run none 5.0M 0 5.0M 0% /run/lock none 3.7G 0 3.7G 0% /run/shm /dev/xvdb 414G 199M 393G 1% /mnt

  • download speed is fast but transfer rate is slow

    - by Ieyasu Sawada
    I've just changed ISP and I'm pretty disappointed with the transfer rate. My previous connection has a download speed of 1.08 Mb/s as seen from this site: http://speedtest.net and the download transfer rate is about 100kb/s for sites that doesn't limit their bandwidth. Now my connection has about 2Mb/s download speed but the transfer rate is dancing from 20-50kb/s . I was expecting a speed much higher than this because of the download speed that I'm getting when I'm testing. The question is what's the difference between transfer rate and download speed, is it normal to have a high download speed but low transfer rate, should the download speed be proportional to the transfer rate?

  • Software for making video tutorial

    - by Ben
    I'm looking for a good video tutorial software. It shouldn't be very complicated. It should be very easy to zoom in on specific locations on screen, as well as make highlights on screen. I have Camtasia Studio, but can't figure out how to do this. This functionality looks ridiculously complicated. http://www.techsmith.com/learn/camtasia/5/editing/zoom-n-pan.asp Free is preferred though low cost is OK too. I have both Mac and Windows. Thanks

  • Ubuntu xrandr rotate issue

    - by user83544
    I've just bought a second monitor for my PC which happens to be a pivot monitor. I've already read lots of forums related to my problem but haven't come across a solution - I have the same symptoms as dozens of posts but no matter whatever I try it just doesn't work. I've already changed the xorg.conf file and added in the device section just under Driver "nvidia" the following for my second monitor: Option "RandRRotation" "on" When I save and reboot I try to rotate my screen with the nvidia X server settings by choosing the second monitor and clicking either "left" or "right" for the rotation. It immediately exits the nvidia settings window and does nothing. I tried within the terminal by typing: xrandr -o right I get the following error: X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 154 (RANDR) Minor opcode of failed request: 2 (RRSetScreenConfig) Serial number of failed request: 14 Current serial number in output stream: 14 I actually manage to rotate it with Option "Rotate" "CCW" instead of "RandRRotation". The problem with this solution is that you get the second monitor in the right position, but any window you open on that screen is practically unchangeable. You can't change the size nor move it, making it useless for reading PDFs, which is the main reason why I bought this second screen to help me write my thesis. Any help is really appreciated. sudo lshw -c video hiram@hiram-linux:~$ sudo lshw -c video *-display description: VGA compatible controller product: nVidia Corporation vendor: nVidia Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:16 memory:f8000000-f9ffffff memory:d8000000-dfffffff memory:d4000000-d7ffffff ioport:dc00(size=12 memory:fbd80000-fbdfffff

  • Database which only holds indexes and last X records in memory?

    - by Xeoncross
    I'm looking for a data store that is very memory efficient while still allowing many object changes per second and disregarding ACID compliance for the last X records. I need this database for a server with not much memory and I can make a key-value store, document, or SQL database work. The idea is that indexes/keys are the only thing I need in memory and all the actual values/objects/rows can be saved on disk do to the low read rate (I just want index/key lookup to be fast). I also don't want records constantly being flushed to disk, so I would like the last X number of records to be held in memory so that 100 or so of them can all be written at once. I don't care if I lose the last 10 seconds worth of objects/values. I do care if the database as a whole is in danger of becoming corrupt. Is there a data-store like this?

  • How can I make WinXP bind to ports other than 1025-5000 for outgoing TCP connections?

    - by Chris Dolan
    (I originally posted a similar question on StackOverflow but readers recommended I post here instead) When you create outgoing TCP connections, most applications let the operating system choose which port to use. Most OSes use the IANA recommended dynamic port range of 49152-65535 for this purpose. But in Windows 2003 and earlier (including XP) Microsoft uses ports 1025-5000. Microsoft lets you change the high end of this range via the MaxUserPort TcpIP registry setting, but I see no way to change the low end. I need to have port 4160 free for incoming connections and on rare occasions an outgoing connection steals that port from me before I bind that port.

  • partitioning problems

    - by Remus Rigo
    I had on my laptop a dual system (Ubuntu 11.04 and Windows 7) and someway the partitions messed-up. Windows stopped from booting, I just got a blinking cursor, but Ubuntu worked fine. I tried to fix the windows boot (fixmbr, fixboot, bootsect /nt60 C:/....) but now grub was overwritten and I have no OS. Finally I formatted the hdd (low format), installed Windows, partition hdd with paragon partition manager and now I want to install Ubuntu, but Ubuntu sees an empty hdd, weird, can anyone tell me what can I do? EDIT: I have created: partition 1: 100MB ntfs - windows reserved (drive B) partition 2: 50GB ntfs win 7 (drive C) partition 3: 50GB ext3 linux partition 4: 'the rest' ntfs for data (drive E) (the swap i will create after)

  • openQRM nagios password reset

    - by Entity_Razer
    Right so, basically the story is that to test a XenServer environment from citrix I deployed a openQRM install from SVN to a ubuntu 10.4 install (on a ESX Environment) All went well installs, I can connect to it, but I can't seem to access the nagios plug in. Every time i wish to go to it i'm asked for a pw, and if I input the pw I wrote down yesterday it just doesn't let me in. I'm trying to reset the password on the nagios plug in now but for the life of me can't find it. Googled high and low for a defenitive working solution but so far no luck. Anyone able to lend a hand ? Cheers ! Ubuntu 10.4 Beta as openQRM openQRM installed from SVN cheers

  • Is it OK to use images of GPD'd code in a CC 3.0 BY video?

    - by marcusw
    I am making a video in which I would like to use pictures of some Linux Kernel code. I am looking to release the finished product under the CC 3.0 BY license, but the Kernel is released under the GPL, which would not allow this if the code is in text format. However, since it will be in low-resolution, incredibly incomplete, non-usable, non-compilable, non-editable (at least without lots of finagling) format, would this constitute fair use or find another loophole to slip through? Thanks for the help, I will understand if this is considered off topic.

  • Mac download speed keeps decreasing

    - by hatorade
    I have a Mac that is getting extremely low connection speed from my WiFi. The other 3 computers in this house have a fast connection. However, on this Mac, once I connect to WiFi it's fast, but as time goes on the speed decreases dramatically. I thought it was the browser or something (Safari) so I downloaded Firefox, but I have watched the download speed decrease consistently as time goes by and right now it's at 8kb/sec instead of the 60-200 range it started at. Any suggestions?

  • Blackjack game reshuffling problem

  • Software to store my password on a crypted file and access it through another password

    - by Fire-Dragon-DoL
    I'm looking for a software that allows me to store some passwords in something like "a text file", access it through a password, read my passwords if required and close it again. I want something really straightforward, double click on file, right click "Add new password", add password, description and close. The file must be really secure, I'll store all my passwords there. I know about some command line solutions but I want my setup to be really fast on reading. Do someone know if such a software exist and can point me in the correct direction? I would like to find it freeware, but I'm ok with some low cost tools too.

  • Powershell overruling Perl binmode?

    - by hippietrail
    I have a Perl script which creates a binary file while scanning a very large text file. It outputs to STDOUT which I redirect in the commandline to a file. To optimize it I'm making changes then seeing how low it takes to run. On Linux for this I use the "time" command. On Windows the best way to time a program seemed to be to PowerShell's "measure-command". This seemed to work fine but I noticed the generated files were larger. On examination I found that the files generated from within PowerShell begin with a BOM and contain CRLF pairs! My Perl script has a "binmode STDOUT" directive and does work correctly in a normal dosbox. Is this a bug or misfeature in PowerShell or measure-command? Has it affected others creating binary files by means other than Perl? Googling hasn't turned anything up so far. I'm using Perl 5.12, PowerShell v1.0 and Windows XP.

  • IIS 7.x Application Pool Best Practices

    - by Eric
    We are about to deploy a bunch of sites to some new servers. I have the following questions about application pools: 1) It seems advisable to have an application pool per website. Are there any caveats to this approach? Can one application pool, for example, hog all the CPU, Memory, Etc...? 2) When should you allow multiple worker processes in an application pool. When should you not? 3) Can private memory limit be used to prevent one application pool from interfering with another? Will setting it too low cause valid requests to recycle the application pool without getting a valid response? 4) What is the difference between private and virtual memory limits? 5) Are there compelling reasons NOT to run one application pool per site? Thanks!

  • video streaming infrastructure advice

    - by Alchemical
    We would like to set-up a live video-chat web site and are looking for basic recomendations for software and hardware set-up. Most streams will be broadcast live from a single person with a web cam, etc., and viewed by typically 1-10 people, although there could be up to 100+ viewers on the high side. Audio and video do not have to be super-high quality, but do need to be "good enough". The main point is to convey the basic info in the video (and audio). If occasionally the frame-rate drops low and then goes back to normal fairly soon, we could live with that. Budget is an issue, so we are in general looking for a lower cost solution that will give us most of what we need in temers of performance and quality. We are looking at Peer1 for co-lo. The rest of our web site will be .Net / Windows platform. We are open to looking at any platform for the best streaming solution, although our technical expertise is currently more on the Windows side.

  • 5v PCI to PCI-X or PCIe adapter?

    - by SiegeX
    We unfortunately have a very expensive ($10K) full-length 5 volt PCI card that we would like to use in the same system as another expensive PCI-X card. As luck would have it, it seems that PCI-X is not backwards compatible with 5v PCI cards. It would be a real shame to have to order a whole new server just to accommodate these two cards together. Does there exist any internal converter/adapter that will allow one to place a full-length 5v PCI card into either a PCI-X or PCIe slot? I've found an external expansion box that suits our needs but it's 1) External and 2) $1100. The only internal adapters I've been able to find go from Low-profile PCI - PCIe; nothing that seems to support full-height, full-length PCI cards.

  • Good free OCR with GUI for correcting mistakes? (for Windows)

    - by Hugh Allen
    I've used SimpleOCR, which has a nice GUI for correcting mistakes. Unfortunately it makes a lot of mistakes! (and suffers other bugs and limitations) On the other hand Tesseract is more accurate but has no GUI at all. Is there a free OCR program for Windows which has a nice GUI and a low error rate? I want it to highlight suspect words (by OCR uncertainty, not just spell checking) and show the original (bitmap) word while I'm editing the OCRed word similar to what SimpleOCR does. Open-source would be best, followed by freeware, then trial / demo / crippleware a long way behind.

  • FreeBSD slow transfers - RFC 1323 scaling issue?

    - by Trey
    I think I may be having an issue with window scaling (RFC 1323) and am hoping that someone can enlighten me on what's going on. Server: FreeBSD 9, apache22, serving a static 100MB zip file. 192.168.18.30 Client: Mac OS X 10.6, Firefox 192.168.17.47 Network: Only a switch between them - the subnet is 192.168.16/22 (In this test, I also have dummynet filtering simulating an 80ms ping time on all IP traffic. I've seen nearly identical traces with a "real" setup, with real internet traffic/latency also) Questions: Does this look normal? Is packet #2 specifying a window size of 65535 and a scale of 512? Is packet #5 then shrinking the window size so it can use the 512 scale and still keep the overall calculated window size near 64K? Why is the window scale so high? Here are the first 6 packets from wireshark. For packets 5 and 6 I've included the details showing the window size and scaling factor being used for the data transfer.

  • NTFS disk mounted as fuseblk in ubuntu 12.10 is very slow and a lot of errors when rsync. Is that not a rare thing?

    - by Pablo Marin-Garcia
    I am having problems with a NTFS disk mounted as a fuseblk in my ubuntu 12.10 through external usb3. When I did a 1.1TB backup with rsync the speed was 1-2MB/s (wiht a ext4 disk speed was 70 MB/s before and after trying the NTFS disk). Also after one hour errors started to appear: rsync: write failed on "xxx": No such file or directory recv_files: "yyy" is a directory #but this file is a FILE not a dir ??!! .... As this is the first time I have mounted the NTFS in linux for heavy usage (the data would be used in windows afterwards), I would like to know if this kind of thinks are common o was only that something became unstable in my system and a simply restart would probably have solved it. This leads me to the these questions: Can I trust fuse for manage NTFS disks? Or is a problem of the NTFS tools in linux not yet totally stables for writing? Do people is still suffering from low performance with fuse-NTFS vs ext4 (in the past I have read about people complaining about this)?
