• How can I get VirtualBox to run at 1366x768?

  - by Joe White

  I'm trying to run Windows 8 in VirtualBox. My laptop's display is exactly 1366x768. Windows 8 disables some of its features if the resolution is less than 1366x768, so I need to run the guest OS fullscreen. The problem is, VirtualBox refuses to run the guest at 1366x768. When VirtualBox is "fullscreen", the guest is only 1360x768 -- six pixels too narrow. So there's a three-pixel black bar at the left and right sides of the display. This user had the same problem, but the accepted answer is "install the Guest Additions", which I've already done; that got me to 1360, but not to 1366. According to the VirtualBox ticket tracker, there used to be a bug where the guest's screen width would be rounded down to the nearest multiple of 8, but they claim to have fixed the bug in version 3.2.12. I'm using version 4.1.18 and seeing the same problem they claim to have fixed, so either they broke it again, they were wrong about ever having fixed it, or my problem is something else entirely. This answer suggested giving the VM 128MB of video memory, and claimed no problems getting 1366x768 afterward. When I created the VM, its display memory was already defaulted to 128 MB. I tried increasing it to 256MB, but with no effect: the guest is still six pixels too narrow. My host OS is Windows 7 64-bit, and I'm running VirtualBox 4.1.18. How can I get VirtualBox to run my guest OS fullscreen at my display's native resolution of 1366x768?

• Create a partition table on a hardware RAID1 drive with [c]fdisk

  - by Lev Levitsky

  My question is, is there a reason for this not to work? Details: I have two 500 Gb drives, and my motherboard RAID support, so I created a RAID1 array and booted from a Linux live medium. I then listed the disks and, apart from the obvious /dev/sda, /dev/sdb, etc. there was /dev/md126 which, I figured, was the mirrored "virtual" drive. Its size was 475 Gb; I had seen that the size of the array would be smaller than 500 Gb when I was creating it, so no surprise there. I did cfdisk /dev/md126, created the necessary partitions and chose write. It's been about half an hour now, I think. It doesn't seem like it's ever going to finish. The only thing about cfdisk in dmesg is that it's "blocked for more than 120 seconds". Doing fdisk -l /dev/md126 in another terminal I see all three partitions I created and a note that "Partition 1 does not start on a physical sector boundary". The table is lost after reboot, though. I tried to partition /dev/sda individually, and it worked, the table was written in about a second. The "not on a physical sector boundary" message is there, too. EDIT: I tried fdisk on /dev/sda, then there were no messages about sector boundaries. After a reboot, I am able to use mkfs on /dev/dm126p1, etc. fdisk shows that /dev/md126 has the same partitions as /dev/sda (but /dev/sdb doesn't have any). But at some point ("writing superblock and filesystem accounting information") mkfs is also blocked. Using it on sda1 results in a "partition is used by the system" error. What can be the problem? EDIT 2: I booted a freshly updated system from a pendrive and was able to create partition table and filesystems on /dev/md126 without any apparent problems. Was it an issue with the support of the hardware? My MB is Asus P9X79.

• What is the best way to connect a 3 switches with a router?

  - by Carlos Morales

  Hello everyone, I'm trying to rebuild the network from my work and I was thinking what is the best way to connect three switches and a router. The router has 4 ports so I thought to connect 2 switches to the router (each switch connected with 2 cables to the router) and then connect the third switch to one of the others with two cables. So is like this, two cables from switch one to the router, two cables from switch two to the router and two cables from switch 3 to switch 1 or 2. So my questions are: Is it better to connect the router to each switch with a cable or the more cables you have the better? If I connect the switch 3 to switch 1 or 2 is it better to connect it with a cable or you get better performance with more cables. If I'm wrong and there is a better or more efficient way to connect them please let me know. The router is a Netgear RP114 (I'll upgrade it to a Sonicwall NSA 240), switch 1 is a Netgear GS748T, switch 2 is a Cisco Catalyst 2924-XL and switch 3 is a D-link DGS-1024D Thank you very much

• Production monitoring for EC2 instances

  - by Janine

  I'm setting up my first production instance on EC2 and want to make sure I have all necessary monitoring in place. There are three different types of things I want to monitor: Is the instance running? EC2 instances can be terminated without warning if the underlying hardware fails, and as far as I know they aren't automatically restarted. So if not, start it back up. Is UNIX running properly? This is the usual stuff about CPU load, disk space, etc. Is the website responding? If not, restart it. I initially set up Nagios on a physical server outside the cloud, but it is really only helpful for item 2. It can tell me if the instance is gone or if the website is not responding, but as far as I can tell it can't execute any commands to fix the situation. My Googling on this subject has yielded a plethora of options - Cacti, Monit, God, Ganglia, and probably more I'm forgetting now. I don't have time to research them all. I am aware of Amazon's Cloudwatch but it doesn't seem to do anything that my Nagios installation doesn't already do. If you already have something like this in place, can you please share what has worked well for you?

• If I partition a drive connected via eSata will it show different partitions when connected via USB?

  - by jeffreypriebe

  I have an odd problem with an external drive. I'm formatting it connected to my laptop prior to connecting it to my router. The HDD enclosure has both an eSata and USB connections. Generally, I connect it via eSata to my laptop. I created my partitions and connected it to the router, but I see partition information that is different than what I created. After chasing leads concerning large HDD size, I mindlessly connected the HDD to my laptop with USB. Lo! I see the same partitions as the router. Attached are screenshots using the same program and the HDD in question. The only difference is the connection. For the first, I connected via eSata and hit "refresh" on the partition program. Then, turned off the HDD, disconnected the eSata cable, and connected via USB. Power and refresh. eSata: reports a total HDD size of 2328 GB, with four partitions (the third being 1.96TB) USB: reports a total HDD size of 280 GB, with three partitions (the third being 279 GB) Any idea why this is happening? It looks like it clearly is an issue of the 4K sector size and not playing nice with the USB enclosure. I tried it eSata and USB in Windows and Linux and it appears consistently that eSata is reporting correctly, USB incorrectly.

• Mac OS X : Open up 3 terminals, run different commands from all for each of them, to set up a develo

  - by taelor

  I'm a Ruby on Rails Web Developer and there is a lot of repetition I go through to start up my development environment. I was wondering if there is any way that I can remove some of this repetition by writing a script, or using a program (like quicksilver) or something to get my work environment going. I know how to use quicksilver to open up terminal, and I even have a saved window group to get my 3 or 4 panes open. The next thing I would love to automatically happen is getting all three to goto a certain directory, and each run different commands. One will start the local server, and in another tab, start a background process. the other would open text mate, and then start a console session, while the last one runs a svn(or git) status. Oh yah, and I would love to go ahead and open firefox, and a few tabs going to a couple of locations. Does anyone have any suggestions on how I could make all this happen in once quicksilver command, or a double click on some type of script on my Desktop?

• Anonymous access to SMB share hosted on Server 2008 R2 Enterprise

  - by bwerks

  Hi all, First off, I have read through this post and a whole slew of non-SF posts which seem to address the same or a similar problem, however I was still unable to fix my problem. I've got three machines in this situation: a domain-joined server that runs Server 2008 R2 Enterprise ("share server") a domain-joined workstation running XP Pro SP3 ("test server") a domain-unjoined test server running Server 2003 R2 SP2 ("workstation") The share server is exposing a share on the network that the test server must access--it's a Source/Symbol Server share for our debugging purposes. I believe visual studio simply accesses the the share with its own credentials in this case, meaning that the share must be accessible anonymously since the test server isn't joined to the domain and there's no opportunity to supply domain authentication. I've attempted a lot of things to avoid the authentication window when accessing the share: I've enabled the Guest account on the share server and given Guest full sharing/NTFS permissions for the share. I've given ANONYMOUS LOGON full sharing/NTFS permissions for the share. I've added my share to “Network Access: Shares that can be accessed anonymously” in LSP. I've disabled “Network access: Restrict anonymous access to Named Pipes and Shares” in LSP. I've enabled “Network access: Let Everyone permissions apply to anonymous users” in LSP. Added ANONYMOUS LOGON to “Access this computer from the network” in LSP. Added the Guest account to “Access this computer from the network” in LSP. Attempted to provision the share using the Share and Storage Management MMC snap-in. Unfortunately when I attempt to access the share from the test server, I still see the prompt and I'm forced to enter "Guest" manually. I also tried this workflow using the local administrator account on a workstation, and the same thing happens both with and without XP Simple File Sharing enabled. Any idea why I'm getting these results, or what I should have done differently?

• What is the difference between disabling hibernation and idling time for a NAS?

  - by Gary M. Mugford

  I have two D-LINK DNS-323 NAS boxes with two Seagate drives in each. The first one is about a year old, the second one about three months. The first two on Monster are each 1.5T drives while the last two on Origami are 2T drives. I have never been overly happy with the Monster drives but, outside of poor throughput on small files, they have been consistently available to all programs after I put a batch file into my startup to do a directly listing of each. I added the two new drives when I added the Origami box. But, watching the dos box that comes up, I rarely see both listed before the box disappears. Other programs, backups, Belarc, even my file browsers, seem to have a dickens of a time seeing O: and P:. Finally, I decided to go into setup and turn off hibernation. Performance HAS been better since and Belarc, for instance, now sees both drives. At the time of poking around, I noticed an Idle Time feature too. What is the difference between the two settings? And for added points, how much trouble am I in for turning off hibernation? The super bonus round ... anything ELSE I should have done? Thanks in advance, GM

• Why Is Volume Shadow Copy Services stopping?

  - by David Mackintosh

  I am running Windows 7 Professional, 64-bit. I am running a backup-over-the-internet software client which depends on the Volume Shadow Copy Services running. Since I installed Service Pack 1 (or rather, didn't object when Windows Update forced Service Pack 1 on me) the backup service is failing to back everything up because VSC isn't running. Most of the time it fails to back up such noise as the Security Essentials database or the Messenger Live contact list -- stuff I really don't care about -- but I don't want to fall into the trap of accepting an Error-state backup as "normal". At the recommendation of the backup software, I have set the VSC service startup mode to be Automatic. When I look in the Event Log, System channel I can see at boot time: The Volume Shadow Copy service entered the running state. ...and then two or three minutes later: The Volume Shadow Copy service entered the stopped state. How do I figure out why VSC is stopping? At the suggestion of the backup vendor, I have already followed the suggestions from http://support.microsoft.com/default.aspx/kb/940184 net stop SENS net stop EventSystem net start EventSystem net start SENS net stop COMSysApp net stop SwPrv net stop VSS cd /d C:\Windows\system32 regsvr32 ole32.dll /s regsvr32 oleaut32.dll /s regsvr32 vss_ps.dll /s vssvc /register /s regsvr32 /i swprv.dll /s regsvr32 /i eventcls.dll /s regsvr32 es.dll /s regsvr32 stdprov.dll /s regsvr32 vssui.dll /s regsvr32 msxml.dll /s regsvr32 msxml3.dll /s regsvr32 msxml4.dll /s net start SwPrv net start VSS net start ProtectedStorage ...and per http://support.microsoft.com/kb/940184 I have deleted the key tree HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EventSystem\{26c409cc-ae86-11d1-b616-00805fc79216}\Subscriptions I have also run chkdsk /F and chkdsk /R on both permanent hard disks. (I had a similar problem with another computer (same OS, same failure, same start point after SP1 install) but the problem went away when I forced Volume Shadow Copy Services to Automatic startup rather than Manual. I did not have to resort to following the Microsoft KB instructions.)

• Have it fixed or buy a new one?

  - by Workshop Alex

  My dual-monitor system has just become a single-monitor system again when the older monitor decided it would be nice to just turn to black. It's a Samsung LCD monitor and is over three years old. Not sure if the warranty is still valid but I just wonder what option would me more efficient: 1) Have the monitor fixed for a small amount. 2) Buy a new monitor for a slightly bigger amount. When monitors were still expensive, I wouldn't doubt about this and would just have my monitor repaired. But prices are so low nowadays, (and repairs are expensive) that I wonder if it's worth the trouble... Of course, I'm in no hurry since I still have another monitor. It's just that I liked the dual-monitor setup. Solved! Just ordered a new monitor. A Samsumg Syncmaster T260HD 25,5". Much more than it would cost me if I just had my old one repaired but I noticed that this one has a build-in TV tuner, plus speakers. It's way more expensive than a repair, but it's worth the additional value it provides.

  I am trying to run a .vbs file on every five minutes. I am trying to do this using windows task scheduler. In Actions tab - New Action, I select the file ("D:\Documents\FC3 Savegames\FC3.vbs") using open file dialog I have made all other setting properly. But whenever the task begin, It opens open with dialog every time. Once I choose Notepad to in open with dialog. Then Another dialog opens from Notepad saying Can not find D:\Documents\FC3.txt file. Do you want to create a new file with three buttons Yes, No and Cancel Help me what is wrong. I feel that white spaces in the file path causing the problem. Added later Well I just fixed this by setting path to shorthand ("D:\Documents\FC3Sav~1\FC3.vbs"). But it still opens "open with" dialog everytime. Now it has two main programs saying "Keep using Microsoft Windows Script Host" and Other Program. This dialog does not open when I run vbs file directly.

• How do I fix a super slow MacBook?

  - by MakingScienceFictionFact

  I'm running a black MacBook 4.1. Intel Core 2 Duo @ 2.4 GHz, 2 GB RAM, 250 GB hard disk drive, bus speed is 800 MHz. It's about three years old in excellent shape externally. I treat this thing like a baby. It used to run awesome, but now it's super slow at everything. I get the spinning pizza of death constantly. It takes a long time to boot up or load any program, even Safari and iTunes. iPhoto is terribly slow. The Internet doesn't work properly and it reminds me of a buggy PC. I've formatted it and re-installed Mac OS X 10.6 (with all updates), and I've done the disk repairs process. As an iOS developer this is driving me crazy, but luckily I have an iMac to work on in the day which is fast. I'm ready to format it again, but that didn't work last time. After the last format, I copied back files from an external drive so maybe the offending files were hidden in there somewhere. Here are the hard disk drive and RAM specifications. It is upgrade-able to 4 GB of RAM. Hard disk drive: The Fujitsu Mobile MHY2250BH is a 250 GB, standard hard disk drive. Its burst transfer rate is 150 Mbyte/s. This is a 5400 RPM drive and comes with an 8 MB buffer. RAM: two sticks of 1 GB DDR2 SDRAM, speed: 667 MHz.

• Weird PCI bug: lots of missed packets, or data comes in "bursts"

  - by Thomas O

  I have an ABIT KN9 motherboard. It has one PCI-e x16 slot, three PCI-e x4 slots and two legacy PCI. My problem is with the legacy PCI (which I shall just call "PCI".) I currently have an Nvidia GeForce 8600 GT (a low end card) installed in the x16 slot and a TV card in PCI #1; the x4 slots are unused, as is PCI #2. I plan to upgrade the graphics card soon, the current card was spare. I sometimes install a USB expander in PCI #2 but it causes a lot of problems - see below. The problem is under Linux (Ubuntu 10.10, Linux 2.6.35-22-generic), but probably under all operating systems (I have not yet been able to test Windows, but I suspect it will do the same as the problems occur on the BIOS/POST side too, e.g. when using a USB keyboard on the expander the keyboard will not work at all) PCI has an enourmous delay, and packets arrive in large chunks. For example, when using the USB expander, my USB mouse lags and jumps in large steps every second or so, while using the motherboard USB does not present this problem. My TV card will only do one or two frames per second, and the program (xawtv) usually times out and crashes. In dmesg, I'm getting messages like: bttv0: timeout: drop=74, irq=154/100476, risc=31f6256c, bits: VSYNC HSYNC OFLOW RISCI for my TV card, and similar timeout issues for my USB expander with a mouse. I received the motherboard, processor and RAM second hand and have only just got around to building it, so I don't know if this problem has always existed, or if it's a result of my set up. If anyone has any hints or solutions it would be appreciated - this is kind of a show-stopper for me.

• Compaq motherboard CQ60 AMD - nvidia chipsed graphic problem

  - by Dritan

  Hi! It nice to have read that you solved this problem this way. I have 2 laptops Compaq CQ60 AMD Athlon with Nvidia graphic cards. the first one is new, when i press power button, it lights up only the ON led in front and nothing else, no fan working, blank screen, no beep.. I don't know what may be the problem. When I put on power adaptor, it lights up only the side power led near dhe power adapter plug but it doesn't light up the front led one. the second one have this problem that it spins the fan, light power and On led, but it doesn't show nothing on the screen blank (even with external monitor). In this case it maybe this problem of the Nvida Graphic Chip and it may need a reflow. I have an hot air station, but I don't know if I should try this or the oven one. Please can you give me any suggestion what to do to solve this. I have read that the solution of the Oven method is just temporary,maximum of three months, do you have the same experience about this? Any suggestion is wellcome.

• How can I copy this quote from PDF?

  - by isme

  I'm reading a PDF copy of Jerome H. Friedman's paper "Data Mining and Statistics: What's the Connection?" using Google Chrome and the Adobe Reader plugin. It contains an amusing quote that I want to copy and paste to my blog. I used the mouse to select the text of the quote and pressed CTRL + C to copy the text. The document looks like this: When I paste the text into Notepad, Stack Overflow, or anywhere else, the product is Wingdings-like gibberish: ????????????????????????|?????????|????? ?????|??????????????????????????????????????????????????|?????????????? ??????????????P????? ?????????????????????P?|?????????|?????????????????????????????????????????????????????? ????????????Þ?????????????????????????????????|???|??????????????????????????? The text should instead look like this: A difference between statisticians and computer scientists in this field seems to be that when a statistician has an idea he or she writes a paper; a computer scientist starts a company. I had to type that text out manually. This is feasible for such a small quote, but how do I actually copy what I see? Is it something unusual about the PDF, the browser, the plugin, or some combiniation of the three?

• running chkdsk /F on a large mounted NTFS image file gets BSOD (Windows Vista)

  - by Citizentools

  Using ddrescue, I've created ISO files from the C: and D: drives on my Windows XP laptop's harddisk (after the laptop stopped booting and chkdsk etc. wouldn't fix it). I was able to mount the 60 GB D.iso file use OSFmount, and successfully recreated the D: drive on another laptop. The C.iso image is more problematic. ddrescue left about 3mb unrecovered of 85 GB total, after multiple passes (no big worries about this) and I'm able to mount it with OSFmount on a Windows Vista laptop. However, when I run chkdsk /F /V on the mounted drive (which was mounted as H:), I consistently get a blue screen (BSOD). CHKDSK makes it through the first three passes, including index fixing and security descriptor fixes, without errors, but triggers a BSOD when it attempts to fix the volume records or bitmap If I attempt to fix the drive by clicking on Properties-Tools-Error checking-Check Now-Automatically fix file system errors, I get an alert box reading "WIndows was unable to complete the disk check." I'd try a tool other than OSFMount, but it's the only thing I've found so far that will mount large ISO files, and it has worked for me up to now in this process. [Update 2011-11-13 18:41 EST] Just ran the same process using the original Windows XP laptop, with a different internal drive, and chkdsk worked like a champ. So the question is still interesting, but decidedly less urgent.

• How do I `SUM` by multiple columns in Excel

  - by dwwilson66

  I have a comma delimited file that includes two columns date/time (which imports as Excel's mm/dd/yyyy hh:mm custom format) and status of 1 or 0. The status represents a piece of equipment either being on or off. I'm trying to generate a graph that will show, hours up vs. down by day. CONSIDER: 1/1/2012 00:00, 1 1/1/2012 03:00, 0 1/1/2012 14:00, 1 1/3/2012 00:00, 0 This tells me that the equipment was up for three hours, down for eleven hours, and then up for thirty-four hours (across two calendar days). However, I would like to generate a graph that shows how many hours PER DAY we were up or down. CONSIDER: 1/1 XXXXXXXXXXXXX----------- (up 13, down 11) 1/2 XXXXXXXXXXXXXXXXXXXXXXXX (up 24) To me, it seems that I need to generate a dataset summing HOURS by STATUS by CALENDAR DAY...but I can't seem to find a flavor of pivot table or nested SUM(IF(SUMIF(...))) combination to make it work. Most troubling is accounting for date changes...in my example above, since my uptime starting at 14:00 on 1/1/2012 crosses midnight, I need to know that 10 uptime hours get totalled with 1/1/2012 and 24 uptime hours get totalled with 1/2/2012. I may be able to do something with a calendar list to drive the date summation, but then I need a way to compare 01/01/2012 to 01/01/2012 03:00 as equal. There's got to be a way along the lines of if(INTEGER-PORTIONS-OF-SERIAL-DATES-ARE-EQUAL,TOTAL-HOURS-IF-VALUE-IS_1,0) but nothing's worked so far. Any suggestions? I've been battling this most of the day, and need a fresh perspective. Thanks

• Win7 System folder contains infinitely looping SYSTEM(!) directory

  - by Matt

  My Windows 7 Enterprise computer has been crashing fairly frequently recently, so I decided to boot up in safe mode and run the TrendMicro client I have installed. It froze about 10 minutes into the full system scan, so in the spirit of http://whathaveyoutried.com, I started scanning each folder individually. When I got to ProgramData, the AV failed with an uncaught exception. I then went down a level and tried scanning Application Data, which failed as well. Imagine my surprise when I open the folder just to see the same folder again! As far as I can tell, this folder loop continues indefinitely. (If you are trying to recreate this, keep in mind that ProgramData is a hidden folder.) I'm actually a bit concerned that these are system folders, as this is a brand-new computer with a clean installation. I guess I have three questions: Has anyone else seen/experienced this before? I'm running Win7 SP1. How do I fix this? I've run CHKDSK \F with no success (although it was incredibly slow). What are the ramifications of an infinitely recursive directory? Theoretically speaking, each link takes up memory, so shouldn't I have no space available on my hard drive? (I've got about 180GB left.) I noticed that the tree view on the left only shows the "linked folder" icon on the deeper folders--does this mean anything special? (I've circled the icons or lack thereof in red.) How can the OS even resolve this aberration? And above all, what would happen if I were to select "Expand all folders"??? :P Matt

• Setting Up My Home Network

  - by Skizz

  I currently have five PCs at home, three running WinXP and two running Ubuntu. They are set up like this: ISP ----- Modem ---- Switch ---- Ubuntu1 -- B&W Printer | |--WinXP1 | |--WinXP2 Wireless |--Colour Printer | |---------Ubuntu2 |---------WinXP3 (laptop) The Ubuntu1 machine is set up as a PDC using Samba and runs fetchmail, procmail, dovecot to get my e-mail and allow me to access the e-mail via imap so I can read the e-mail on any PC. I'd like to set up the network like this: ISP ----- Modem ---- Ubuntu1 ---- Switch ------WinXP1 | | |--WinXP2 B&W Printer Wireless |--Colour Printer | |---------Ubuntu2 |---------WinXP3 (laptop) My questions are: How to configure Ubuntu1 to act as a firewall. How to configure Ubuntu1 to provide a consistant user authentication across the network, at the moment Samba provides roaming profiles for the XP machines but the Ubuntu2 machine has it's own user lists. I'd like to have a single authentication for both XP machines and linux machines so that users added to the server list will propagate to all PCs (i.e. new users can log on using any PC without modifying any of the client PCs). How to configure a linux client (Ubuntu2 above) to access files on the server (Ubuntu1), some of which are in user specific folders, effectively sharing /home/{user} per user (read and write access) and stuff like /home/media/photos with read access for everyone and limited write access. How to configure the XP machines (if it is different from a the Samba method). How to set up e-mail filtering. I'd like to have a whitelist/blacklist system for incoming e-mails for some of the e-mail accounts (mainly, my kids' accounts) with filtered e-mails being put into quaranteen until a sysadmin either adds the sender to a blacklist or whitelist. OK, that's a lot of stuff. For now, I don't want config files*, rather, what services / applications to use and how they interact. For example, LDAP could be used for authentication but what else would be useful to make the administration of the LDAP easier. Once I have a general idea for the overall configuration, I can ask other questions about the specifics. Skizz I have looked around for information, but most answers are usually in the form of abstract config files and lists of packages to install.

• Wireless card on HP laptop not working

  - by D. Strout

  I just bought an HP Envy m6-1125dx online from Best Buy. When I got it home and started it up, the wireless card did not work well - at all. I could connect, but any real usage would cause the connection to start dropping every 30 seconds or so, and it would be really slow. Taking another look at the reviews on the Best Buy site, it seems only a few others had this problem, so I took it to my local Best Buy and exchanged it for another unit. Got it home again and the card had the same issues. Which leads to my dilemma. First: does this model have several different cards that it could come with? Mine is a Ralink RT5390R (on both units I received). If it does, then I can keep exchanging until I get a unit with a different card. I wouldn't ask this, except it seems weird that only a few people mentioned this issue, so I thought that might be one possibility. I looked in to replacing the card with a different one myself, but it seems that HP blocks certain wireless cards. However, some people reported success in replacing the card, and this site said it was only an issue on "older HP computer[s]". Can anyone confirm this? Finally, if that fails/will not work, does anyone know what I can get through Best Buy? I am concerned that they will not put any different card than the Ralink, and after two of those, I don't want that. Can I ask Best Buy support to use a different card? Can they even get another card from HP? I guess the base question is: should I attempt to replace the card myself (two days via Amazon to get a new card), should I try to get the laptop repaired through Best Buy (two - four weeks), should I go for a different model laptop from Best Buy, or should I try a different unit of the same model (three's the charm?).

• Software/hardware to build video streaming server?

  - by Sasha Yanovets

  I am looking for a video streaming server solution, something like online TV server, with ability to make live broadcasts in the internet. What software could you recommend for that? What kind of hardware it should run on, should be there anything special? I am looking for a solution that could be scaled up to at least 1000 simultaneous users online with good resolution of video. I think it is good to have general answer on what direction to choose. But here more details on my specific case: I just looking for a solution almost from scratch. We have some video content that we've produced, but it is not delivered over internet yet. We do not tied to any particular vendor for now. We want to make 24 hours of steaming three 8 hour blocks with change of content every day. We want the ability to make regular live broadcasts. I guess we will need to have several options of streaming quality (low ~56 kb/s mid ~273 kb/s). Some terms just foreign to me (like play-truncation rate), if you could point out what parameters we should avare of, it would be great. Uplink to the internet is to be determined. We plan to start from something and scale up on the way. If you are already have some kind of media streaming server, just describe its configuration here (hardware, OS, software), peak number of concurrent users it serves. I think it could help people approaching this task.

• GNU Screen and Finch Not Playing Nicely

  - by Sean M

  I use finch for instant messaging, and for persistence, finch is one of the things that runs in my screen session. There are three main computers that I access my screen session from, and each works at a different screen resolution. Because of the different resolutions, when I switch computers, I use screen -rd to attach to my screen session. Using screen -x results in problems. When I attach to the session, though, finch experiences display problems. I have to wait up to several minutes for finch to become responsive - it doesn't redraw properly at all. Trying to switch between chats just writes ^n and ^p, or ^(1-9) for numbers. It fixes itself after some time. Using ctrl-l does not help. Switching back and forth between screen windows does not help. This is an annoying behavior that I don't experience with any other applications running in screen. Is this a bug in screen or finch, and if not, what can I change about my configuration to correct it ? (would appreciate it if "finch" could be used as a tag for this instead of or in addition to "pidgin")

• How to use AND/OR Building Block content in a Word 2007 template

  - by JimmyJames

  I am creating a Schedule of Work template and am successfully using Developer Tab and Quick Parts to allow user to choose content on an "either/or" basis: either A; OR B; OR C; etc., essentially choose one option from many. One Building Block control, one paragraph, nice and clean. Now what I need to do but cannot seem to figure out, is how to allow user to choose content on an "and/or" basis: either A AND B; A OR B AND C; B AND D AND E OR F; etc., essentially choose several options from many on a variable basis. One Building Block control, maybe one paragraph, maybe three or more paragraphs. Not so clean. I thought of building choice options for all possible paragraph combinations, but I can have as many as 7 or 8 different paragraphs, and that solution quickly becomes unworkable. Multiple controls--some of which will be left unused doesn't work either, since I cannot find an easy way to have a "Choose or Delete" control that actually deletes if "Delete" is chosen. Recommendations are most welcome.

• linux: mount old ATA disk to USB adapter

  - by 130490868091234

  I am trying to recover data from an old Linux that was installed in a computer on an ATA hard drive. I found a ScanLogic Corp. SL11R-IDE IDE Bridge (04ce:0002), an ATA adapter to USB 1.0 like the one in the picture: and after switching it on, I plugged it into a laptop with Ubuntu 12.04. I am used to the drives being automatically mounted, but this one doesn't show up in /media. After doing a dmesg, all I got is this: [215298.671924] usb 2-1.1: new full-speed USB device number 5 using ehci_hcd [215298.767330] scsi19 : usb-storage 2-1.1:1.0 [215299.841701] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd [215300.017258] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd [215300.197050] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd [215300.372730] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd I tried plugging in the adapter to the three different USB ports in my laptop (one of them USB 3.0), but got no luck with any of them. I get different devices under, for example: /dev/bus/usb/003/002 or /dev/bus/usb/002/004, but I don't get any /dev/sdbN links. The output blkid -o list -c /dev/null is just the laptop's partitions. I have tried taking out the jumper, putting it as master and as CS Enabled, but didn't change the result. Any ideas?
