  • Installing ubuntu on inspiron 1720, can I dual boot?

    - by sososo
    Can I dual boot ubuntu with on a inspiron 1720 (it is running windows 7). One issue is I don't have space on the c:\ drive, but other partitions have space. Will that cause any issues? This is just to play and learn with, and I don't want to ruin my main windows install doing this. I don't think my laptop is powerful enough for a virtualbox install (only 2gb ram).

  • MS Publisher 2003 - hangs when saving to desktop

    - by Chris
    We have a win 7 home prem pc, amd cpu, 8G ram, plenty of free disk space. Whenever user is working in publisher 20003, and tries to save a publisher 2003 document to the desktop, the save as dialog hangs and takes 2-3 minutes to display the desktop save location. I've tested excel 2003, it has no problems immediately displaying the desktop save as location and saving the file.

  • What are the most likely bottlenecks determining the performance of CamStudio screen recording?

    - by Steve314
    When doing screen recording, I can get a frame rate of maybe 15 frames per second for the full screen on my 1080p monitor using the XVID codec. I can increase the speed a bit by recording a region, changing screen modes, and tweaking other settings, but I'm curious what hardware upgrades might give me the biggest bang for my buck. My PC is budget, but modern... Athlon 2 X4 645 (3.1GHz, quad core, limited cache) processor. 4GB single channel DDR3 1066 RAM. ASRock motherboard with NVidia GeForce 7025/nForce 630a Chipset. ATI Radeon HD 5450 graphics card - 512MB on board, not configured to steal system RAM. I dual-boot Windows XP and Windows 7. For the moment, XP is my bigger performance concern as it's still my getting-things-done O/S as opposed to my browser-host O/S. My goal is to make a few programming-related tutorials. For a lot of that I don't need screen recording - I can make up some slides, record audio with the PC switched off, yada yada. When I do need screen recording, I'll mostly be recording Notepad++, Visual Studio or a command prompt. Occasionally, I may be recording some kind of graphics or diagram program and using my pre-Bamboo cheap Wacom tablet - I have the CS2 versions of Photoshop and Illustrator, but I'd much more likely be using Microsoft Paint. Basically, what I'll be recording won't be making huge demands on the machine - but recording a fair number of pixels (720p preferred) will be useful. What's particularly wierd - not so long ago I still had a five-year-old Pentium 4 based PC. And (with the same 1080p monitor) it could record at not far from the same frame rate. So clearly the performance issues are more subtle than just throw-money-at-it. My first guess would be that the main bottleneck is the bandwidth for transferring data to/from the graphics card. Is that likely to be correct? In support of that, see this [Radeon HD 5450 review][1] - the memory bandwidth is only 12.8 GB/s. If you can't get data out of graphics memory quickly, you can't transfer it back to the system memory quickly. Apparently, that's slower than some top-end cards in 2002.

  • Linux Best Practices

    - by Zac
    I'm a life-long Windows developer switching over to Linux for the first time, and I'm starting off with Ubuntu to ease the learning curve. My new laptop will primarily be a development machine: 6GB RAM, 320 GB HD. I'd like there to be 2 non-root users: (a) Development, which will always be me, and (b) Guest, for anyone else. I assume the root user is added by default, like System Administrator in Windows. (1) I'd like to mount /home to its own partition, but how does this work if I have two user accounts (Development and Guest)? Are there 2 separate /home directories, or do they get shared? Is it possible to allocate more space for Development and only a tiny bit of space for Guest in GRUB2? How?!?! (2) I'm assuming that its okay that all of my development tools (Eclipse & plugins, SVN, JUnit, ant, etc.) and Java will end up getting installed in non-/home directories such as /usr and /opt, but that my Eclipse/SVN workspace will live under my /home directory on a separate partition... any problems, issues, concerns with that? (3) As far as partitioning schemes, nothing too complicated, but not plain Jane either: Boot Partition, 512 MB, in case I want to install other OSes Ubuntu & non-/home file system, 187.5 GB Swap Partition, 12 GB = RAM x 2 /home Partition, 120 GB I don't have any bulky media data (I don't have music or video libraries, this is a lean and mean dev machine) so having 320 GB is like winning the lottery and not knowing what to do with all this space. I figured I'd give a little extra space to the OS/FS partition since I'll be running JEE containers locally and doing a lot of file IO, logging and other memory-instensive operations. Any issues, problems, concerns, suggestions? (4) I was thinking about using ext4; seems to have good filestamping without any space ceiling for me to hit. Any other suggestions for a dev machine? (5) I read somewhere that you need to be careful when you install software as the root user, but I can't remember why. What general caveats do I need to be aware of when doing things (installing packages, making system configurations, etc.) as root vs "Development" user? Thanks!

  • Exchange-Server Query

    - by Rudi Kershaw
    First, a little background. I've recently been taken on as a web and software developer for a small company, who has no other in-house IT support. They've been asking my opinion on lots of IT subjects that are quite far out of my comfort zone. I'm definitely not a network admin. Their IT consultancy contractor is pushing them to upgrade their dedicated exchange server, even though it seems like the one they currently have has a lot of life left in it and is running problem free. They say it's "coming to the natural end of it's life". They want to install a monster with a Xeon E5-2420, 32GB RAM, 2x 1TB HDDs, Windows Server 2012 and Microsoft Exchange 2010. They want to charge a small fortune for it. Basically, this system seems massively over the top seeing as it won't be doing anything else other than running as an exchange server for a company with less than 25 email accounts. My employers also have a file server system in-house that hosts three web apps, an SQL server, their local domain, print server and shared folders. That machine is using the same specs as the proposed new one, and it is barely using any of it's potential. I asked if Microsoft Exchange 2010 could be installed on their file server, but they said that MS Exchange can't run on the same system as an SQL server because for some reason they will eat up each others resources (even though the SQL server isn't touching 1% of the current system's CPU or RAM). My question is really, are they trying to rip my employers off? Could MS Exchange be installed on their other server (on a virtual instance or not), or does the old one even need replacing at all? Going with their current suggestion will cost the company in excess of £6k, and it seems entirely unnecessary. I apologies, because I know this is probably a little thin on details, but if I carry on I could end up writing a massive essay that no-one will want to read. I've been doing my research, but I'm not knowledgeable enough make any hard decisions. Let me know if you need any more details. Thank you for any help you can offer. Further Details: The new exchange would need to support Outlook Web App, 25 users, a few public mailboxes, and email exchange with Blackberries.

  • Why is Windows "stuck" on the Welcome screen for so long?

    - by Perdana Putra
    I use Windows 7 with a laptop specifications processor core (Core i3), 2 GB DDR3 RAM, the remaining capacity on the system partition (25 GB). I do not know why the "welcome screen" takes a long time (about 40 sec), but yesterday only took about 10 sec., I tried to defragment the disk and do a virus & spyware scan with antivirus, but still the "Welcome screen" comes along. How do I get the welcome screen to pass by faster when Windows boots up?

  • How to bring Paging File usage metric to zero?

    - by AngryHacker
    I am trying to tune a SQL Server. Per Brent Ozar's Performance Tuning Video, he says the PerfMon's Paging File:%Usage should be zero or ridiculously close to it. The average metric on my box is around 1.341% The box has 18 GB of RAM, the SQL Server is off, the Commit Charge Total is 1GB and yet the PerfMon metric is not 0. The Performance of the Task Manager states that PF Usage is 1.23GB. What should I do to better tune the box?
