• Extend university wifi network [migrated]

  - by asfasdoiuh ouhouhouh

  i live in a university campus and i can get wifi signal on the outside of my window but not in the house. The solution i use at the moment is a usb wifi dongle outside connected to my laptop but the lack of an internal antenna make the connection quite unreliable at times. So i was trying to find another solution to improve the reception of my network. One idea is to setup a router on the outside (in a place with stronger signal) and redirect the connection inside the house with an ethernet cable but the problem is that our Uni Wifi is managed by a capitve portal (BlueSocket with DNS redirection to login page) and the authentication has to happen on the mac address that connect to the net (so the client appliance in this case). If I use a router with Mac-Clone capability i will be able to be redirected trough the captive portal on my laptop computer and login from there or i need to setup my router to fill in the login page by itself? There are other hardware/software solutions i can use to get what i want? Thank you all

• Is there a NVIDIA driver (for a 7-series card) that will actually work for 12.10?

  - by DS13

  I see many similar topics on this, but I've tried all their suggestions, and nothing has worked. ISSUE: I do a clean install of Ubuntu 12.10. Boots fine with the “nouveau” graphics driver – graphics are very slow and choppy. The three other driver options in Ubuntu (official NVIDIA drivers), all result in a variation of the black screen on boot up. There will be NO access to a command line/GUI in anyway what-so-ever (tried every option recommended out there, but the system is unusable at this stage). I can only reinstall, and try different drivers…and I only ever get one shot at it. QUESTIONS: Does anyone know of a NVIDIA driver that will actually work with a Nvidia GeForce 7350LE? Or a 7-series card in general? This is my second computer, and I’m just trying to get a working install of Ubuntu on it. I don’t want to put much money into it, as I have seen Ubuntu run great on much older/less capable machines. I’ve got a decent Intel processor (2.3Ghz), 2GB of RAM, 320GB hard drive, 32-bit architecture, and there is no other O/S installed. It appears as if the graphics card is holding me back. Should I just buy a cheap graphics card (non-NVIDIA) to put in as a replacement? TRIED SO FAR: -all drivers available in Ubuntu *all fail -manual install of some different NVIDIA drivers *all fail -also tried installing the generic kernel, Nvidia driver doesn't work in 12.10 *no difference -every method suggested to at least get a command line after switching to a NVIDIA driver *all fail

• How can I logoff and go to stand-by via Win XP script?

  - by Peter

  I am looking for a way to write a script (of any sort) that would both log me off my local Windows account and also immediatedly put the computer to sleep / stand-by. I've found solutions that can do one or the other but not logoff and then sleep all in one script. The SHUTDOWN command doesn't offer this and I can't find any other options either. This is for Win XP, SP3 right now but someday soon I'll want a Windows 7 solution as well. Thanks for any ideas or an explanation as to why this isn't possible. :)

• Cannot connect to FTP server from external host

  - by h3.

  I have a FTP server (vsftpd) setuped on a Linux box (Ubuntu server). When I try to connect with a computer on the same network everything works fine as expected. But as soon the IP is external it won't connect.. I first assumed the port was blocked, but then: localserver:$ sudo tail -f /var/log/vsftpd.log Wed Jan 13 14:21:17 2010 [pid 2407] CONNECT: Client "xxx.xxx.107.4" remotemachine:$ netcat svn-motion.no-ip.biz 21 220 FTP Server And it hangs there. Do any ports other than 21 need to be open?

• Wifi won't connect to certain networks

  - by Dave M G

  As I write this, I'm in a coffee shop on my laptop, and I am trying to connect to the free wifi network they offer. Every time I select their network from the wifi applet drop down menu, it connects for a second and then disconnects. At the same time, I have my Android phone with me, and it connects to the coffee shop's network without problem. There are a couple of people around me also using the same network with no issues. I asked the staff to check and as far as they can tell there is no problem with their router or anything. I have tried rebooting, but it has not made a difference. I have double and triple checked that I am using the correct WEP password. As an added wrinkle, when I connect to another network, it seems to connect (although I can't use them because they are paid gateway services). So I'm able to ask this question now because I have tethered my laptop to my phone, but it's slow and a workaround, not a solution. All indications are that it's a problem with my computer against this one network. Why would that be and how can I fix it?

• How to force Windows to call the partition it installs on C:?

  - by maaartinus

  I'm going to install Windows XP from a CD and want to make sure it calls the partition it lands on C:. The target partition is the first one on a SATA disk, which is not the first one in my computer. There's no IDE disk there. I don't think I can swap the disks, as I'm using a fake RAID and really don't want to get problems with it. The target partition is on a normal disk. I know it may be unimportant, but I don't want to run in any problems I can avoid. I've seen a question slightly related to it, but I'm not going to install from a USB.

• USB 3 adapter for a dell 2850 with PCI (or PCIX) ports

  - by Don Dickinson

  Does anyone know if there is a plain PCI (or PCIX) USB 3 adapter. i understand the bandwidth of PCI < USB3, but it still beats the heck out of USB 2. i have some older dell 2850s that do not have the PCI E ports that most USB 3 adapters require. i'd really like to get usb3 in those servers. i searched the internet but didn't see any. the local computer store said they only had pcie adapters. tia, don

• Suggestion of device WiFi range in it's spec. Possible?

  - by SeeR

  I have router Draytek Vigor 2100VG at home almost in the center of it. The farthest point at my home is my balcony, ~12m from it. I have constant wifi signal range problems with some of my devices, but not with others. Notebook Lenovo W510 - no problems Nokia Home Music - always on 10m - no problems Sony PS3 - always on 7m - no problems Sony tablet S - problems around 6m Sony PSP - problems around 8m Sony PS Vita - problems around 8m Nokia E63 - problems around 8m I'm curious why my Notebook don't have any problems even on the balcony? I guess it has better hardware or uses more power for transmission. This information is really important when you want to buy new device/computer, so my real question is: Can device wifi range can somehow be found/suggested from official hardware technical specification? If not Is there some web page with wifi range reviews?

• Is there a convenient method to pull files from a server in an SSH session?

  - by tel

  I often SSH into a cluster node for work and after processing want to pull several results back to my local machine for analysis. Typically, to do this I use a local shell to scp from the server, but this requires a lot of path manipulation. I'd prefer to use a syntax like interactive FTP and just 'pull' files from the server to my local pwd. Another possible solution might be to have some way to automatically set up my client computer as an ssh alias so that something like scp results home:~/results would work as expected. Is there any obscure SSH trick that'll do this for me? Working from grawity's answer, a complete solution in config files is something like local .ssh/config: Host ex HostName ssh.example.com RemoteForward 10101 localhost:22 ssh.example.com .ssh/config: Host home HostName localhost Port 10101 which lets me do commands exactly like scp results home: transferring the file results to my home machine.

• What's the typical latency for key strokes using an ssh connection on a local wifi network?

  - by dan

  I develop software on a Macbook Air 1.6 Ghz but find running Rails test suites and generators on this computer very slow. I'm thinking about buying a Linux tower to put on my local wireless network to do my Rails development on. I would want to use my Macbook Air and ssh into the Linux box and do my development with Gnu Screen, vim, etc. Can I expect the keystroke and echo latency for a ssh session between two machines on a local wireless network to be negligible? Does anyone develop using this kind of local setup?

• USB Hub powers down in sleep mode on Win 7 64

  - by Andy B

  This question has been asked before but not answered. I would like the USB hub to remain on in sleep so I can wake up the laptop from an external keyboard and mouse. I have set all the device drivers by unchecking allow this device to be powered down and disabled selective suspend in control panel but the hub still powers down. If I plug a keyboard or mouse directly in to the PC they remain powered and wake the computer its only when they are connected through the hub there is a problem. I have another PC running Win 7 32. If I set this up in exactly the same way the hub remains powered in sleep. Both PC's are Toshiba Satellites with multi-core celerons but one runs Win 7 32 the other Win 7 64. BIOS settings are the same. Any help would be appreciated even confirmation that this is a feature of Win 7 64.

• An entry-level programmer's best option [on hold]

  - by user134409

  I am facing a puzzle and I am not sure the best way to make a decision. In my spare time besides playing video games I got around to develop some games, nothing fancy, just small projects to get a better grasp at programming. After I finished college and got my BA in Computer Science, I got a job as web developer at a small firm. The next few months were very stressful as I had no previous experience and tried my best to make up for it. But after 6 months my boss told me I was inefficient and not very independent and let me go. To my credit, the help from the senior was very limited, I did learn a lot but I have learned by myself. For example they told me to do a UI in BackboneJS and I took me a while but I got it working (even if it was poorly designed). But I managed to do it all by myself because my senior was very busy and he did not have time even for my questions. Now I have found a new job again in web development but I am very afraid of what is going to happen next. I am afraid because I don't want to take the job and then be fired again after a couple of months, I get the feeling that this will be very bad on my CV, job hopping is like a red flag. They want to hire me but I am aware that they are working with new technologies and maybe I will end up not coping with it. So the question is: Should a entry-level programmer be better off with a starting job in QA, testing and work his way from there? I did learn allot from my first job but it was a moral blow when they decided to fire me. I do have a low self-esteem and I know my skills as a programmer are not that great. But I like programming and want to get better and I want to have a long career in it so that basically my pickle. Thank you in advance for the answers.

• Windows 2008 x64 displays SP1 when SP2 is installed

  - by Graham Powell

  After setting up a Windows 2008 x64 server (not R2), I installed a number of Microsoft updates. After installing these updates, the computer reports that it has SP1 installed, not SP2. I believe the culprit is KB917607, which allows Windows 2008 to display .hlp files. Now I have to upgrade Internet Explorer on this server, and it won't install without SP2. I am very leery about reinstalling SP2, as I have installed a large number of post-SP2 updates, and I've had issues after reinstalling SP2 in similar circumstances. How can I fix Windows so it reports the correct service pack?

• Help me convert my gaming headset plugs (mic & stereo sound) to a single 2.5mm monaural plug

  - by Flotsam N. Jetsam

  I have a seldom used piece of computer hardware I'd like to connect a gaming headset to. The headset has two 3.5mm plugs (mic and sound) like this: The jack I need to plug into is a 2.5mm monaural (don't ask me why--I know it sounds goofy but it's for someone else who's very picky). I googled a few different ways but I could only find splitters such as this for going from 2 x 3.5mm to 1 3.5mm. If I could find one that could combine it properly to 1 3.5mm, I could then find a 3.5mm to 2.5mm adapter. I know I could probably vivisect and work something out, but I need it to be very clean. Any ideas?

• How can I disable HTML5 content in popular browsers like Firefox and Chrome?

  - by HRJ

  The bad thing about Flash video was that it required a third-party plugin to play the content. The good thing was I could select which content to play; using the click-to-play feature in Firefox and Chrome. But now that HTML5 video is getting popular, I see a lot of ads popping into view again. They are not only a distraction, they hog resources on my computer and make the fans spin full speed. Is there a way to disable HTML5 audio/video content by default, and enable it only selectively?

• Stop Windows 7 from installing critical updates

  - by Rico

  I have disabled Windows Update on Windows 7, but it still downloads and installs critical updates. As with Windows XP, these updates occasionally create problems. But in XP, once I disabled automatic updates, the OS did not override my settings and continue to download and install critical updates. After the most recent critical update to Windows 7, every time I boot up, the USB devices connected to a single port through 4-way hub don't install. I have to unplug the hub from the computer then plug it back in. Then the devices install. I can use System Recovery to solve the immediate problem, but I'd like to disable automatic updates entirely. Why does Windows 7 not respect my settings like Windows XP did?

• Tool to launch a script driven by modem activity

  - by Will M

  Can anyone suggest a software tool (preferably under Windows XP or later) that would launch an application or script in response to a phone call being received on a landline phone line connected to a data modem on the same PC? or, better, in response to a sequence of touch-tones being played over such a phone line. This would allow, for example, using the telephone to manipulate firewall settings so as to create another layer of security in connection with remote internet access to that computer. I seem to recall seeing tools to do this sort of thing in the days before broadband internet access, when there was more attention to various tips and tricks for the dial-up modem, but a few attempts at Google hasn't turned anything up.

• WSUS Looping 2 updates on 2003 servers

  - by Ericrobert

  Good afternoon, Hopefully I can articulate this so that people understand my problem. We have WSUS on windows server 2008. We have 8 Windows 2003 servers. There is an update ready to install KB2982792. We install it then it says there is another update to install KB2728973. Then it says there is another update to install, again KB2982792. This goes on and on. Talked to microsoft support and they confirmed that the update was infact installed and applied to the computer (Checking untrusted certifactions confirmed that for these updates) and their suggestion was to just "Hide update". This is fine except on the WSUS server it still shows failed updates which is not okay with our policy. I'm here to ask for help figuring this out and what I can do to trouble shoot it. Thank you in advanced.

• Weird files in User folder

  - by Vervious

  In my user folder (C:/Users/myAccount/) theres a set of interesting hidden files that I've never seen before (right now it's a fresh install of Windows 7 Ultimate). These are: NTUSER.DAT, ntuser.dat.LOG1, ntuser.dat.LOG2, and NTUSER.DAT(whole chain of numbers and letters).TM.bif, NTUSER.DAT(whole chain of numbers and letters).TMContaineretcetc.regtrans-ms, and another similar one. When I try to delete them, it says the system is using them. I've never seen these files before. Are they ok to delete? Or should I leave them in my home folder? I always keep "Show hidden files" as well as "Show System files" checked, since I prefer being able to see all the files on my computer. If I shouldn't delete them, is there at least a way to tidy them up a bit? Thanks.

• Have there been attempts to make object containers that search for valid programs by auto wiring compatible components?

  - by Aaron Anodide

  I hope this post isn't too "Fringe" - I'm sure someone will just kill it if it is :) Three things made me want to reach out about this now: Decoupling is so in the forefront of design. TDD inspires the idea that it doesn't matter how a program comes to exist as long as it works. Seeing how often the adapter pattern is applied to achieve (1). I'm almost sure this has been tried from a memory of reading about it around the year 2000 or so. If I had to guess, it was maybe about and earlier version of the Java Spring framework. At this time we were not so far from days when the belief was that computer programs could exhibit useful emergent behavior. I think the article said it didn't work, but it didn't say it was impossible. I wonder if since then it has been deemed impossible or simply an illusion due to a false assumption of similarity between a brain and a CPU. I know this illusion existed because I had an internship in 1996 where I programmed neural nets that were supposedly going to exhibit "brain damage". STILL, after all that, I'm sitting around this morning and not able to shake the idea that it should be possible to have a method of programming to allow autonomous components to find each other, attempt to collaborate and their outputs evaluated against a set desired results.

• WDS (Wireless Distribution System) not work [migrated]

  - by xdevel2000

  I've a dlink di-524 as main router (192.168.0.1) connected to Internet and a second router (192.168.0.2), a tplink wr841n, with WDS enabled and correctly configured to "join" with dlink. After I connect via wireless a laptop (192.168.0.100) to tplink and both work good but with the laptop I can't go to Internet. It seems as WDS not work. With the laptop I can only ping the tplink but other ping (the dlink or other LAN computer not responding). What's the problem? Perhaps also the dlink must have the WDS option? Thanks.

• Synckolab will not start automatically

  - by EBV2010

  We have a Kolab server for e-mail, calendar and contacts with Thunderbird for a client. The add-ons are Lightning and Synckolab. The workstations are Kubuntu, most 10.04, some 11.10. It basically works but for one nagging problem: the automatic sync (that is, the settings that starts Synckolab upon start of Thunderbird and every x minutes as per setting) does not fire. We went through the whole routine: setting it, setting it to zero and back to any number of minutes, stopping/starting Thunderbird or the entire computer to make sure it sees and sets it. In the configuration console is reflects the changes. But still it will not automatically fire Synckolab. Manual syncs work without any problem (none that we've seen - it reflects all the added, changed etc calendar events). In short: Synckolab does not fire automatically with any setting who have thought of.

• OS X software updates download but don't install

  - by ridogi

  I've got three 10.6 computers that won't install OS X updates. Checking for new software will show about a dozen updates (Security updates, Safari, iPhoto, printers, etc) and if choose install it downloads them. After downloading and then clicking restart the computer sits at the purplish sky desktop with no progress bar, and then after about 3 minutes it goes back to the login window (without ever installing or restarting). If I then select check for updates the same updates will all be presented and I can repeat the process. Manually downloading and installing an update such as 10.6.8 combo updater works as it should, and then check for updates no longer presents that particular update as an option. This seems to be the result of some setting or 3rd party application as I've got 3 out 7 computers experiencing this exact same problem. What could cause this and how can I fix it?

• how to debug BSOD irql_not_less_or_equal error

  - by Sev

  So I'm getting the irql_not_less_or_equal BSOD. I tried looking at the event viewer for potential causes, and cannot find any. I also checked the CPU temperature in BIOS right after the error and that was fine. I've tried 2 sets of RAM chips already, both give the issues. The error doesn't happen consistently...it happens daily, but many hours can pass and it won't happen, or only 10 minutes can pass and it might happen again. By the way, just bought the parts and built the computer myself a couple of weeks ago. How to debug the cause for this?

• What is the best objective way to measure language popularity trends? (What's better than TIOBE?)

  - by Eric Wilson

  The best way to get data on computer language popularity that I know is the TIOBE index. But everyone knows that TIOBE is hopelessly flawed. (If someone provides a link to support this, I'll add it here.) So is there any data on programming language popularity that is generally considered meaningful? The only other option I know is to look at the trends at indeed.com, which is inherently flawed, being based on job postings. It isn't like I would make a future language decision solely based on an index, but it might provide a useful balance to the skewed perspective one obtains by talking to ones friends and colleagues. To illustrate that bias, I'll point out that based on the experience of those I personally know, the only languages used professionally today (in order of popularity) are Java, C#, Groovy, JavaScript, Ruby, Objective C, and Perl. (Though it is evident that C, C++ and PHP were used in the past.) So my question is, everyone bashes TIOBE, but is there anything else? If so, can anyone explain how we know the alternative has better methodology? Thanks.
