• Ubuntu One has high CPU usage but no syncing

  - by Peter

  over the weekend I updated my computer to Windows 8. So far Ubuntu One was running smoothly, but ever since the update (clean, new install) Ubuntu doesn't sync any more. In Windows 7 it would start to sync at full internet speed as soon as I drop a file. But now in Windows 8, as soon as I drop a new file into the Ubuntu One folder, CPU usage goes up to about 50 % and no network traffic occurs. This stays like that for a couple of minutes, CPU usage goes back to normal and then the client says that all is in sync - which isn't true. Is it too early for Windows 8? Do others have the same problem or is there something I can do about it? I try a couple of different things, and realized that if the file size is 20 MB the files get uploaded. The original file was 1.5 GB. I also didn't work with 200, 100 and 50 MB large files. But even with 20 MB large files, the upload is very slow and not steady. The log give plenty of this error: - twisted - ERROR - Failure: exceptions.TypeError About which I don't know the meaning. By the way, the account works just fine on the Ubuntu 12.04 partition. Any help is greatly appreciated. -Peter

• Acad 14 SOLIDS disappeared, DWG file doesn't open correctly

  - by MikeD

  I made a drawing in Autocad 14 (Win XP) containing of mostly SOLID's. I saved and re-opened it multiple times without any problem. Before I last saved it I viewed my drawing using the SHADE functions. After re-opening all my SOLIDS have disappeared. I spent numerous hours searching for a solution, tried SATFIX.ARX , AUDIT, RECOVER without success (ACIS error - which should be gone after applying SATFIX), changed my computer locale from German (decimal = comma) to English (decimal = dot) but my screen remains empty (and yes I tried to recover from a .BAK, too) I also tried to export (the non-display drawing) into DXF and can confirm that all my objects are in there, but re-opening the DXF results in a huge ACIS error list again I am desperate - please can someone help - thanks! Mike

• Ubuntu 12.04 Freezes at Bootup

  - by Ryan Yu

  I have an Acer Aspire One Model AO722, that has a dual-boot configuration with Windows 7 Home Premium and Ubuntu 12.04. Processor: AMD C-50, 1.00GHz 2.00GB ram, 64-bit, AMD Radeon HD 6250 Graphics. I installed Ubuntu two days ago, and since then, loading it has been sporadic. Windows 7 still loads just fine, but Ubuntu will sometimes freeze. First time I booted Ubuntu up, it ran no problem. Worked with it for half an hour, then shut down the computer. The second time I booted it up, it froze after ten minutes when I was trying to set up Thunderbird. Third time, same thing. Fourth time, it froze about 5 minutes after bootup when I was trying to connect to my wifi. Fifth time, it ran no problems for about 5~ hours. Then, three consecutive times I've restarted (what is it, the 6th, 7th, and 8th times?) it has gotten to the login screen, I've entered my password, all the text on the page disappears as if its going to load my desktop, and it freezes. A minute ago when I booted Ubuntu up for the 9th time, it loaded the desktop fine. Who knows if it'll crash soon; probably, though. Any ideas?

• Fiction that includes BASIC programs [closed]

  - by Clinton Blackmore

  Back in what must've been the mid-80s, when every microcomputer included BASIC and Choose Your Own Adventure Books were really popular, there were some novels that had BASIC programs listed in the text, for you to type in and further enjoy. For example, as I recall, in one of these books, the adventurers were infiltrating an undersea base (and eventually wiped the bad guy's data storage [I do believe it was a hard drive, even though they were uncommon then]). One of the programs involved a game were you piloted a submarine and had to avoid or shoot sharks. The code was in BASIC; minor changes (such as 'CLS' - 'HOME') had to be made for your specific computer, and it used good old 40-column text-mode to display the action. IIRC, the plot never depended upon the programs. My question is, does anyone else recall these sorts of books? Do you know any titles that I could look for, or of any online? I am toying with the idea of writing a story like this (no, not in BASIC!), and would really like to see how it was done, back in the day.

• How to prevent Windows Home server waking for backup

  - by Andronicus

  Since changing the motherboard in my Windows home server it has been switching itself on every night to perform a scheduled backup. I don't want this to happen though, I want to switch the server on using Wake on lan, but I want to manually perform backups if/when required. I know I can disable backups of each computer, and the machine wont turn on, but I want to allow manually triggered backups, or automatic backups if the homeserver is on, but if its in sleep mode, I wish it to stay in that state unless I wake it. How can this be achieved?

• Why FreeBSD won't reboot after kernel crash?

  - by Max Kosyakov

  Once in a while I get my server running FreeBSD 8.0 amd64 fail due to bad memory (incompatible with motherboard) modules. Each time it happens, the box stalls with the last note saying that it will automatically reboot in 15 second, but it never does. How do I fix this? I need computer to reboot after kernel crash, unattended. (Please do not recommend to replace memory, as soon as I get the modules, I will, but I need a quicker solution that will not require me to stand still next to the box just to press the reset button each time it crashes.)

• Simulating network latency for localhost connection on Windows 7

  - by nitro2k01

  I need to simulate network latency to a program running on the local computer, connecting to a local service. Thus far I have tried dummynet (a windows build of ipfw) which I got working after some trial and error. While it generally works, I can't seem to get it to filter localhost traffic. Even after adding a rule from any to any which affects external traffic, this makes no difference for local connections. I would appreciate if anyone knows how to simulate local latency using dummynet or a different tool. The tool should be able to simulate latency generically in IP packets, (TCP and UDP) and not be protocol specific.

• Will people respect a Masters of Science in IT w/software engineering concentration from RPI?

  - by twneale

  Here's my thing: I got my undergraduate degree in political science, then a law degree. Then I figured out that I love programming and I'm pretty good at it too. It's fun and rewarding enough for me that I'd prefer to do it for a living over almost any form of pure law practice. So I'm looking at getting a masters degree to put some weight behind a possible career switch. If I actually want to develop software (web, in particular), would people in programming circles respect a master's of science in IT? Specifically, consider as an example the MS in IT from Rensselaer Polytechnic Institute (with a concentration in software engineering). Here's the home page: http://www.rpi.edu/IT/graduate/masters_program.html In particular, I mean to draw a contrast between IT as specifically contemplated by the RPI masters program (an interdisciplinary tech/business program) and other MS degrees in computer science or software engineering that focus more on the science and technical aspects. I guess I want to make sure that other programmers would respect my credentials and not consider me as different or underqualified based on the connotations of the phrase "IT". I believe RPI has an unimpeachable reputation for hard science, and the program seems excellent, but it still matters to me how people in industry would perceive it.

• What if you've been asked to develop a site and the client later introduces Ts&Cs that you'll breach whilst doing your job?

  - by Matt Lacey

  Disclaimer : this is all made up. Honest. And it represents no clients or employers living or dead, blah blah blah, etc. [Allegedly] As part of a website I've built, I've now been provided the Terms and Conditions of site usage to display on the site. These terms--which must be agreed to to access the site--include my (or any visitor to the sites) compliance with a number of clauses. Many of these clauses refer to general computer use and are not tied specifically to use of the site. Some of these clauses refer to things I have had to previously do as a legitimate part of my job and would expect to have to do again. When I've raised similar issues previously my line manager has said just to ignore it but that doesn't seem to be the professional thing to do. So, what do I do? Abiding by the terms would mean that I could no longer work on the project and would cause issues with my employer and the owner of the business the site is being created for. Ignoring them could lead to possible future issues with the business owner and is not something I'm necessarily happy with (the deliberate breaking of a legal contract). Neither option is one I'd choose and could have major consequences. Any thoughts?

• trouble with internet connection - slow to open web pages if they open at all until I put VPN on and then they open ok

  - by Caroline Coleman

  I am having problems with my internet connection. At the moment I am on a mac and connected through a netgear wireless router. The internet connection either won't open a webpage at all or if it does it takes ages. However if I turn my VPN on the pages open at a normal speed. Also skype functions OK and I seem to be able to download files ok. I have tried connecting with a wire between the router and the computer and it makes no difference.

• Cisco 1841 Box and Watchguard XTM21-W

  - by Corey

  I have never set one of these up before and need a little assistance. Right now we have a T1 line coming in from Sprint to a Cisco 1841 and then on to our router. However, when I plug the Cisco 1841 into Port 0 and the router into Port 3 it does not work. In Port 1 I have my management computer plugged in. We have one subnet and this must be easy but I cannot figure out how to make this work. When the firewall is plugged in then I get no internet or network access.

• How do I prevent home folder files and folder from showing on the desktop as icons in Linux Mint 15?

  - by N Rahl

  I have a fresh install of Mint 15 with Cinnamon and I can't find an option to hide all icons on the desktop. In settings-Desktop there are only options to show/hide the home folder, trash, etc, but no option to hide the contents of the "Desktop" folder. How do I hide the $HOME folder contents from appearing on the desktop in Linux Mint 15? UPDATE: It actually looks like the icons on the desktop are the contents of the $HOME folder, not $HOME/Desktop. ** Question was edited to reflect the fact that it was the user's home folder icons showing, not just "my computer", "trash", etc.

• Converting PDF eBooks into a Kindle format

  - by Ender

  Over the past couple of years I've amassed quite a collection of guides, tutorials and ebooks in PDF format. A lot of these are quite useful for work, especially PDF documentation, and rather than have to be at a computer every time I want to read how to do something in Sitecore or to read through a software testing ebook I'd like to do it on my brand-spanking-new Kindle. However, even though there is now a native PDF reader on the Kindle due to the nature of PDF's they are practically unreadable. The text doesn't wrap due to how PDF's are sized and so far after a bunch of Google searches I've yet to find a viable solution to get my PDF's converted into a readable Kindle format. Sometimes these books have code or pictures/tables in them, but most of the time they're text-heavy and to be honest I'd be surprised if there wasn't a free tool to handle the converting of PDF to one of the (seemingly many) Kindle formats. So, can anyone help me out with this?

• Time issues on the Network -- How to find the Root Cause

  - by Jeff

  A number of application servers started erroring out in my domain. Troubleshooting led me to a missconfiguration of NTP. I fixed the issue, but I don't know how the issue arose in the first place. The only errors I can find are System Error: 1097 Source: useenv System Error: 1058 Source: useenv System Error: 1030 Source: useenv System Error: 1000 Source: mmc How else can I find out why NTP started acting up on my domain? Is there any troubleshooting steps to diagnose why my DC started pulling from a random timeserver with the wrong time? EDIT: Current issue actually remains: the two 2003 DCs are not syncing with the PDC (a 2k8 box). w32tm /resync -- The computer did not resync because no time data was available.

• Error message when renaming files on a network drive stored in Windows 7 favorites

  I have a network drive mapped to a share on a Window Server 2003. I have a shortcut to this drive stored in my Windows 7 favorites. When I double click the shortcut and then rename a file on the drive, if the file is longer than 8 chars or contains spaces then I get this error The drive that this file or folder is stored on does not allow long file names, or names containing blanks or any of the following characters:... If I get to the network drive by click on it in the tree under computer then it works fine. Is there a way to get round this?

• data recovery from unallocated harddisk partition

  - by user42151

  Hi I accidentally deleted a partition which mainly served as space I put my data, labeled D: drive. The partition wasn't subsequently formatted though, following the delete incident. Obviously the D: drive doesn't show up as it usually does when I run Windows 7. In the "Computer Management", on clicking the Disk Management I clearly see the space is now labled as unallocated. question: How do I go about recovering my data. Perhaps what the effective data recovery software I can use to resolve this issue. Thanks

• Why can't I share my printer on Windows 7?

  - by Edward Tanguay

  I have Windows 7 installed on two computers. I can share folders between them fine. However, I can't seem to share printers between them: when I right-click on the printer I expect to see "share printer" but there is no option for that. When I read about "share printers" in the Windows 7 help, it talks about this computer "not being able to connect to a home network", yet they seem to be connected fine (I can share files between them). Why can't I share printers between the computers if I can share files?

• Chipset GPU causes a massive slowdown

  - by zyboxenterprises

  My AMD Radeon HD 7700 recently broke (fan stopped working and GPU overheated), and now I'm running on internal chipset graphics, and it causes a massive slowdown of the whole PC. I've changed the graphics memory from 32MB (minimum) to 256MB (highest), and it hasn't made any difference whatsoever. I'm using Windows Aero, and disabling it should have made a small difference, but it didn't; the whole PC is still slow. I know that it's not the computer build, because I built it myself, and it was a lot faster when it had the AMD Radeon HD 7700 in it, which is the reason why I believe it's the internal chipset graphics that are causing the problem. Is this behavior normal? I don't have the cash right now to go out and buy a new dedicated GPU. I'm using an ASRock N68C-GS FX motherboard with an AMD FX 4100 (overclocked to 4.3GHZ), with 4GB RAM. The overclock was an attempt to resolve this issue, and it isn't related to this issue that the integrated graphics is causing a slowdown.

• Why does my Mac address reset after reconnecting?

  - by Mr.Student

  I have ubuntu 12. I'm changing my mac address with ifconfig wlan0 hw ether xx:xx:xx:xx:xx:xx which works. However when I restart my connection my computer resets my mac to my original mac address. I'm guessing that this happens because something calls... ifconfig wlan0 down ... do something before connecting ifconfig wlan0 up ... connect to designated access point I want my mac address to however be the same no matter how many times I disconnect and reconnect, whether to another network or the same one. Also it would be nice to turn off the auto-connect feature for my network-manager with out having to edit each individual connection. Lastly I would like to know how to connect to a wifi network through the terminal and not via gui network manager ubuntu provides.

• Isopropyl okay to use on MacBook screen?

  - by Archagon

  I've always used a mixture of isopropyl alcohol and distilled water to clean my computer screens (50% water and 50% * 70% isopropyl). From what I understand, these are exactly the same ingredients used in most commercial screen cleaners, perhaps even more diluted. I recently used this solution to wipe off my 2010 MacBook Pro screen, and there don't seem to be any problems, but this support page explicitly says not to use isopropyl. Now I'm worried that I might have inadvertently damaged something. I'm also concerned because I once managed to dissolve the surface rubber lining of one of my mice with the isopropyl solution, and the MacBook Pro display has a thin rubber bezel keeping the glass in place. Why would Apple single out isopropyl on their support page? Should I be concerned?

• Preventing SSH RSA host key warnings for change of key vs IP address

  - by Adam M-W

  I have a network with DHCP enabled, and also a computer that dual boots operating systems and has different SSH keys on each (and yes, I would like to keep different keys on each rather than copying the same identity/private key to each). Because the IP address does not change between operating systems because the MAC address is the same, when connecting to ssh, even when not using the IP address but the hostname via DNS/mDNS, I get the warning: Warning: the RSA host key for 'hostname' differs from the key for the IP address '192.168.1.172' Offending key for IP in /Users/user/.ssh/known_hosts:37 Matching host key in /Users/user/.ssh/known_hosts:38 Are you sure you want to continue connecting (yes/no)? How can I surpress the warning when the hostname differs from the IP address for that hostname, but retain the ability to check host keys are the same for each hostname? (each OS has a unique hostname)

• Installing linux on a crippled machine via network boot?

  - by networkbooter

  I have a somewhat ancient Toshiba laptop (which can't boot from USB) that I want to install linux on (probably Ubuntu). I'm currently running Windows XP and Ubuntu via Wubi. I want to delete these OSs and replace with Ubuntu only. The laptop does have a network boot option. I'm wondering if the easiest way might be to setup a network boot server on my other computer (which runs Ubunutu) and boot the laptop from it. Could this allow me to install Linux on the laptop? I can't seem to find instructions on the 'net as to how to go about doing this.
