  • Can you suggest some DIY PC specs for 1) Value, and 2) Future 'upgradability'?

    - by user17381
    Hi, I'm considering building a new desktop PC from components. For the last 7/8 or so years I have almost exlusively used laptops, and so have fallen behind a bit with knowledge of various hardware technologies. Anyway, now I'm considering building a new desktop machine. Mainly for development work, but also would be nice to do a bit of gaming. The two main criteria are: I would like the first build to be relatively low cost. I would like to select components that will allow me to upgrade in the future without throwing too much away. Can anyone recommend a setup? Thanks

    - by aravind.udayashankara

  • On Windows 7, how can I tell if a recording is multi-channel without third party tools? [migrated]

    - by engineerchuan
    A customer has an audio that is confidential and can't send it to me. He also would not like to install other tools. He has a basic Windows 7 install. Is there any way to tell whether the recording is one channel or two channel? Normally, I would just get the audio and soxi it. Or, I would tell him to install Audacity or equivalent sound editor and open it up. I also thought that if you right clicked and looked at the size, bit rate, and length, you could get number of channels but bit rate already factors in number of channels. Sorry I'm not giving you a lot to work with.

  • Font size of emacs in ubuntu

    - by Ispinfx
    I use emacs in ubuntu and I use Monaco 10 as its default font. However, the font rendering seems a bit odd compared to my gnome terminal with the same font size: It's a bit smaller and not as clear as that in the terminal. I've tried to avoid simply this with size 11 but it's too large for me. How can I make it the same as its look in the terminal ? Any help is appreciated :) UPDATE: I should tell you the above on is GUI emacs running a shell, and the below is the gnome terminal. On the right are their correspond font settings. Both 100% capture with font size 10: (left: emacs, middle: terminal, right: gedit) One more (gvim's):

  • What do I need to Mod a Unreal Engine 3 game?

    - by RoadSideWarrior
    what I am looking for is some advise making a mod for a certain game and how I would go about making it. The game I am talking about is Blacklight: Retribution and what I wan't to know is; Is it possible? And if so, what programs will I need? It is an online only game so I was unsure how plausible a mod would be for it. Plus I have never made a video game before, but I do like the game and I wanted to do some things with it. Additionally, this will be my first time making anything video game related so I would appreciate any advise. To expand a bit, I plan to add something simple at first. A mod that would let you spectate another player in the first person. Then I plan do something a bit more complex where I want to make so the game optionally always records you playing (in short intervals most likely or you would run quickly out of memory). After all that is done I would add items, armor, weapons, and maybe make a map or not I am not sure but this in a shell what I hope to do. I don't know much about these things but I am reading anything I can get my hands on. So if this is overly ambitious or just plain out not a possibility any advise on what I should look to instead will be welcomed warmly. Thank you.

  • MySQL com_select?

    - by symcbean
    I'm looking to tune my query cache a bit. According to 7.6.3.4. Query Cache Status and Maintenance in the manual: The Com_select value is given by this formula: Qcache_inserts + Qcache_not_cached + queries with errors found during the column-privileges check However in 5.1.5. Server Status Variables it suggests that this is maintained by the DBMS. Having said that mysql> show status like 'Com_select%'; Always returns a value of 1 - and I'm pretty sure I've run more than one non-cached select query on my database since it started. It looks as if other people are similarly confused. Is this status variable redundant? Which bit of the manual is wrong? TIA

  • Recursion in F#

    - by MarkPearl
    Things are slowly coming together – I was able to look at a bit of F# code and intuitively know what it was going to do (yay)… So today I saw a blog post by Bob Palmer on Fibonacci numbers in F# which inspired me to look at bit into recursion. First the C# example… class Program { public static void CountDown(int n) { switch (n) { case 0: Console.WriteLine("End of Count"); break; default: Console.WriteLine(n); CountDown(n-1); break; } } static void Main(string[] args) { CountDown(10); Console.ReadLine(); } }   In F#, the equivalent would look something like this… open System let rec CountDown n = match n with | 0 -> Console.WriteLine("End of Count"); | n -> Console.WriteLine(n); CountDown (n-1); CountDown 10 Console.ReadLine()   Pretty simple stuff. With F# you when making recursive calls you need to explicitly declare that the function is recursive with the “rec” keyword. Otherwise the code is pretty easy to read and self explanatory.

  • fwupd to update OCZ RevoDrive firmware gets a 'Permission denied' error

    - by Late
    Try as I might I just don't get it working (http://www.ocztechnology.com/ssd_tools/OCZ_RevoDrive_and_RevoDrive_X2/). There's another thread here with an similar issue here: Command is giving me "bash: ./fwupd: cannot execute binary file" I'm running command ./fwupd /dev/sdb which keeps returning me bash: ./fwupd: Permission denied I have tried running both bit versions available of fwupd with both of the latest 32- and 64-bit Ubunty 11.10, running the OS from an USB stick, but to no avail (could this be the problem?). In the other thread it was suggested that chmod +x fwupd (or chmod 0755 fwupd) should resolve this issue, but at least for me it has been for naught. It was also suggested to install certain libraries, but those were already included in the Ubunty build and I didn't have any luck after updating with apt-get. I also tried giving fwupd more privileges, r, x and w but same charade, run it in different ways from different places (where I'd have the fwupd present, ofc) among other things. What I also tried is giving the Ubunty 10.04 LTS a shot but it didn't even launch on either of my computers, though that's not the issue here. If anyone has any ideas on what the problem is and how I could get this working, it would be most appreciated!

  • Is learning C# as a first language a mistake?

    - by JuniorDeveloper1208
    I know there are similar questions on here, which I've read, but I recently read this post by Joel Spolsky: How can I teach a bright person, with no programming experience, how to program? And it got me thinking about my way of learning and whether it might actually be harmful in the long run. I've dabbled with various languages but C# is my first serious one, I've read "Head First C#" and created a few projects. But after reading the post above I've found it a bit disheartening that I may be going about it all wrong, obviously I respect Joel's opinion which is what has thrown me a bit. I've started reading "Code" as recommended in the reading list and I'm finding it pretty hard going, although enjoyable. I feel like it's taken the shine off of my "noobish hacking about" in Visual Studio. So now I'm unsure as to what path I should take? Should I take a step back and follow Joel's advice and start reading? I guess my main aim is just to become a good programmer, like everyone else, but I don't want to be going into bad practice by learning a .NET language when someone who's opinion I respect thinks that it is harmful. Thoughts?

  • Which Language Next? Python? Ruby? [closed]

    - by Ryan Craig
    I am a beginning Webmaster (relatively), with 2+ years of php experience. I also have some java training and a bit of .net. My company is now close to redeveloping the website that I work on, which is coded primarily in php, but has some poorly-written .net in part as well (it's confusing and ill-planned, but I didn't make any of those decisions. Can anyone say action-oriented .net and JScript?). So, I'm trying to decide which language I should learn next to quickly develop a new site. I will probably just redevelop it at first in php because I'm very comfortable with it. However, I'd like to migrate in the next year to something newer and more forward-thinking. This being said, .net is out of the question a little bit. We need cheap developers who are fast and can get pages up quickly. In this part of the country, part-time .net developers are hard to find. So, we need something that will be pretty standard in the next few years, but we have some .net SOAP 1.1 APIs that we use on our actual service (separate from the corporate website), that we will need to integrate part of the site with. Developing with php and SOAP is much more difficult than doing the same thing. So, I may have to develop the API collaborative part in .net just to be easy, and then I'd like to use something else that is fast, flexible, forward thinking, and will be relatively standard and easy to find developers for. So, any ideas? Python and Django? Ruby on Rails? Another framework? Thanks for your thoughts. Sorry, I know this was long, but it's all very convoluted and confusing so I needed to be slightly long-winded.

  • Virtualbox install 12.04 guest: "pae not present"

    - by Peter.O
    I get this message while trying to install Ubuntu 12.04 as a guest in VirutalBox 4.1.18, on an Ubuntu 10.04 host. This kernel requires the following feature not present on the CPU: pae Some host specs: The host's kernel is: Linux 2.6.32-41-generic-pae GNU/Linux lscpu (host): Architecture: i686, CPU op-mode(s): 32-bit, 64-bit grep --color=always -i PAE /proc/cpuinfo   does show pae in its output. The 12.04 iso used is: ubuntu-12.04.0-desktop-i386.iso As a comparison/check, I downloaded and installed Linux Mint 13 Cinnamon to the same host on the exact same VM (I just changed the .iso image). It worked fine. Its iso is: linuxmint-13-cinnamon-dvd-32bit.iso It seems (to me) that I have pae.. what is going on here? Update: I had assumed that Linux Mint also required pae (being Ubuntu based), but I've just run;   grep --color=always -i PAE /proc/cpuinfo   in the Mint VM.   It showed no output.   So it seems the issue may lie with VirtualBox.   If that is the case, how can I get Virtualbox into pae mode?

  • How do I get the Windows 7 installer onto a USB drive?

    - by Rod
    I'm having trouble installing Windows 7 onto my old laptop. The problem appears to be the laptop's DVD-ROM no longer seems to work. Sucks. So, I'm trying to figure out how to get a bootable USB with my Windows 7 DVD info onto it. I found this link here on superuser.com: http://superuser.com/questions/66948/place-a-bootable-iso-on-a-usb-drive That looks good, except for the detail about making the USB bootable. It said that the OS you're making it bootable on must be the same as the machine you're going to be installing it on. I can't do that. The machine I would make it bootable from is a 64-bit version of Windows 7. The target machine is 32-bit. So, how's this going to work?

  • Permission issue when deleting folders

    - by nate
    I can't delete some folders and some actions are being denied because I do not have administrator access. But in my user account it says i am an administrator. I also just upgraded from Windows Vista 64-bit to Windows 7 64-bit, but I had this problem before upgrading, but now I am being denied more things. I also can't reorder the way files are sorted in folders. I can sort them through the default means, but I literally can't drag and drop them if I want to reorder them. I don't know if this is another problem or if it is related. Let me know if you need more information. Thanks!

  • Elevate the weight of browsing history in Google Chrome's autocomplete

    - by maayank
    Google Chrome has the feature of auto-completing web addresses while you type them in the address bar. Alas, it gives absurdly more weight to Google's own auto-suggest v.s. my own browsing history, which seems a bit foolish - if I regularly (i.e. twice a week) check a certain website with the keywords "foo bar ponies" in its url, it is reasonable to expect that I will want to visit that site again and not other sites. While a bit subjective, to the very least I would expect such URLs to be in the list Chrome suggests, even if not at the top. Is there some plugin/secret option that alters the default behavior?

  • "ant" is not recognized as command in Windows

    - by user1294663
    This is my first time developing Android applications. I'm developing an Android app on Eclipse on Windows 7. I would like to run the Android app from the Windows 7 command line interface.

What is the solution to this problem?

  • Logical and Physical network topologies

    - by t.thielemans
    I'm trying to understand the difference between logical and physical topologies but it's a bit confusing to me. Cisco states these as logical topologies, but from my understanding these should be physical topologies? This is what I understand so far: Physical PtP: desktop directly connected to a desktop Multiaccess: several desktops connected to a medium with access to each other (Cisco Ring image, how should I view this in a live situation?) Ring: several desktops directly connected to each other creating a loop? Logical PtP: two desktops (virtually) connected to each other with intermediairy devices in between MultiAccess: (don't have a clue) Ring: (don't have a clue) Could anyone help me out and perhaps explain the difference a bit more detailed? Online I can't find any useful topics. I am using the Cisco Network Fundamentals book.

  • How to use psexec without admin privileges on target machine?

    - by HighCommander4
    Is it possible to use psexec to execute a command on a remote machine without having admin privileges on the remote machine? I tried running psexec \\<machine> -u <username> -p <password>, where <username> and <password> are non-admin credentials, but I get an "access denied" error I can remote desktop into the remote machine with the same credentials without any problems. My local machine is running Windows 7 Enterprise 64-bit, and the remote machine is running Windows Server 2008 64-bit. I do have admin privileges on the local machine. EDIT: To all the people who are downvoting this question: I am not trying to circumvent any sort of security measure. I can already run the process on the remote machine by remote desktop-ing into the remote machine and running it. I'm simply looking for a command-line way to do something I can already do through a GUI.

  • [Linux] Bind/map Character to alt+[some key]?

    - by Paul
    OS: Ubuntu In programming and various terminal programs (Screen, Vim) the [, ], { and } tends to be used a lot. I'm using a Norwegian keyboard where these are placed such that I have to stretch my fingers a bit too long for whats comfortable. To make it easier I though I'd try to make alt+[some key] be one of these characters. Is there a way that I can bind, say alt+æ (Norwegian letter) to '{' system wide? Btw, is such thing called binding, mapping or something else? I'm getting a bit confused by the terms... :)

  • why is drop box syncing so freakishly slowly in my linux virtual machine?

    i am setting up a linux virtual machine (windows 7 64 bit host, ubuntu 64 bit guest, using virtual box) and i just installed drop box and set it to sync. I've only got about 2Gb in there so i figured it should take just an afternoon, but it's going at about 0.5 kB/second and says it will take about 60 days. I usually get about 200 kB/second in the host OS, and downloading straight from the dropbox website through firefox in the ubuntu VM i get about that, but sync is really slow. any tips?

  • Installing sharepoint web service disabled when trying to install BizTalk adapter

    I have a MOSS Box, with Microsoft Office SharePoint Server 2007 SP2 (Danish server), .net 3.5 SP1 on a Server 2008 64 bit (where IIS is running 64 bit too). When I fire up the BizTalk installer and wants to select the SharePoint Web Service, this option is disabled/grayed out. Any ideas as how I can enable the option again? (It states that there are one or more prerequisites missing but I can't figure out which). I found some reference stating that I basically had to "toast" the MOSS box and install WSS 3, but that is NOT an option... Any suggestions? :o)
