  • Slow Internet / Can't change brightness on 2010 Macbook AIr running 12.10 Ubuntu

    - by user103441
    The title really says it all. I haven't been able to change the brightness of my monitor since putting Ubuntu on it. I started off with 12.04 and then decided to see if 12.10 would fix the issue. The internet is also a fair bit slower than I am used to, especially when downloading. Apart from these two issues, everything goes very smoothly. If anyone could offer any advice or solutions, I would be very grateful.

  • Why Your Abstract Wasn't Selected

    - by AllenMWhite
    We're anxiously waiting to hear from PASS which sessions were selected for the 2014 Summit in November. It's a big job to go through the hundreds of submissions and pick the sessions that will appeal to the people who will be paying over $1,000 to attend this annual event. As I am also waiting to hear the results, I saw this article addressed to actors who didn't get cast for the part they worked so hard to audition for, and it seemed appropriate to address the same issues for would-be Summit speakers....(read more)

  • Why does Ubuntu 12.04 dual boot fail?

    - by Tranas
    Fresh install of XP followed by a fresh install of Ubuntu 12.04 results in the following error: error: unknown filesystem. grub rescue and the machine will not boot. Prior to the 12.04 install, XP worked fine. During the 12.04 install, all partitions and free space was visible, and the install seemed to complete without issues until the error message. Although I can fix the MBR via recovery console in XP and allow the machine to boot to windows, why is GRUB/Ubuntu trashing the boot sequence?

  • Problem Loading a DLL (4 replies)

    I'm having some issues now that I can't see what I'm doing wrong. I'm Pinvoking a non WindowsAPI DLL (I mean, not a dll provided on windows).

  • Learning PHP from beginner to advanced [closed]

    - by Liam
    I've dabbled with PHP for a few years now and I'm capable of most of the basic things, building login forms etc but from my time on here I've noticed there's so much more I need to learn, like best practices, security issues etc and so I want to learn everything from the very basics. In the past I've used forums and browsed the web for snippets of code only I think this has led to my bad practices, can anybody recommend books or Valid, recommended learning sources? Thanks in advance!

  • Native PHP vs exec()

    - by resting
    Just wondering, assuming no security issues, that is, you're in total control of the command passed to exec(), is there a difference (in terms of speed or standards) between using exec() vs native PHP? Example just to name a few use cases: Using the DirectoryIterator vs exec(ls -1, $output), to list all files. List 100 files from the 99th file onwards (that is, file 100 to 199) Count total number of files in directory.

  • SEO FAQ For Small Business 7 of 10 - How Long For SEO Results? (SEO Results Time Frame)

    The hours and effort needed to increase the visibility of your small business website depend greatly on your marketing plan and which keyword you're going after. A year-long optimization campaign is not unheard of for a large site. If your site is less than three or four months old, or the domain is expiring in less than a year, you may have issues with high rank despite your best efforts as these are 'red flags' to the search engines.

  • Is it possible to dual boot Mac OSX Lion with Ubuntu 12.04?

    - by tofu_bacon
    I've read that it can be dangerous for your computer to try to run Ubuntu and that the safest option is to run it on an external hard drive. Is this true? (I don't want to run it through a Virtual Machine.) I would prefer to dual boot it, given that my hard drive has so much space. Update: So does this mean that even if I have Ubuntu installed, that my data would still be at risk due to, say, stability issues?

  • How do I stop Sophos anti virus from scanning directories that are under source control

    - by user26453
    From googling it seems its well known that SophosAV as well as other AV programs have issues with how they interact and can inhibit source control utilities like TortoiseHG or TortoiseSVN. One solution is to exclude directories under source control from on-access scanning as detailed here on Sophos's support site. There is a corollary article that mentions some issues related to this, namely the need to place multiple entries for exclusions based on the possibility of the location being accessed through the short vs. long name (e.g., Progra~1 vs. "Program Files"). One other twist is I am using a junction to relocate my user directory, C:\Users\Username, to a second hard drive, E:. Since I am not sure how this interacts I have included the source control directory as they are nested in both locations. As a result, I have included the two exclusions for the on-access scanning exclusions (and to be on the safe side on-demand exclusions as well, although this should only come into play when I select a parent directory of the exclusion to be scanned on-demand, but still). You'll notice I have no need to add extra exclusions for those locations based on short vs. long name distinctions. The two exclusion I have then, for both on-access and on-demand scanning exclusions are: C:\Users\Username\source-control-directory E:\source-control-directory However, this does not seem to work as TortoiseHG still lags terribly in response to any request as AV software starts scanning when the directory is accessed via TortoiseHG. I can verify without a doubt that Sophos is causing the problems: I can completely disable on-access scanning. Once this is done TortoiseHG responds very fast to all operations. I cannot leave this disabled obviously, but since the exclusion don't seem to be working, what next?

  • Reverse Proxies and AJAX

    - by osij2is
    A client of ours is using IBM/Tivoli WebSEAL, a reverse-proxy server for some of their internal users. Our web application (ASP.NET 2.0) and is a fairly straightforward web/database application. Currently, our client users that are going through the WebSEAL proxy are having problems with a .NET 3rd party control. Users who are not going through the proxy have no issues. The 3rd party control is nothing more than an AJAX dynamic tree that on each click requests all the nodes for each leaf. Now our clients claim that once users click on a node in the control, the control itself freezes in such a way that they don't see anything populate. Users see "Loading..." message appear but no new activity there afterwards. They have to leave the page and go back to the original page in order to view the new nodes. I've never worked with a reverse proxy before so I have googled quite a bit on the subject even found an article on SF. IBM/Tivoli has mentioned this issue before but this is about all they mention at all. While the IBM doc is very helpful, all of our AJAX is from the 3rd party control. I've tried troubleshooting using Firebug but by not being behind the reverse proxy, I'm unable to truly replicate the problem. My question is: does anyone have experience with reverse proxies and issues with AJAX sites? How can I go about proving what the exact issue is? Currently we're negotiating remote access so assume for the greater part that I will have access to a machine that's using the WebSEAL proxy. P.S. I realize this question might teeter on the StackOverFlow/ServerFault jurisdictional debate, but I'm trying to investigate from the systems perspective. I have no experience with reverse proxies (and I'm unclear on the benefits) and little with forwarding proxies.

  • Is anyone using KVM in production?

    - by Andy Shellam
    I've been trying to set up a pair of servers utilising KVM on Ubuntu 9.10 to host 8 virtual machines between them and ended up with various issues from the VMs freezing, to not powering on. I had one virtual server set up and running and was setting up a second, when any operation involving OpenSSL would cause the VM to lock up in a weird way - all network traffic would cease, it wouldn't process logins on the console, but it wasn't taking any CPU time off the host. The first virtual server was identical and worked perfectly. Another VM I tried to setup had installed Ubuntu fine then refused to reboot, throwing kernel exceptions to do with XFS. I've now installed Citrix XenServer 5.5 on both hosts, and am now setting up my third VM with absolutely no issues. I also had the same experience when I tried VMware, but I preferred Xen as it appears to give more features on the free license. My question is am I just unlucky with KVM, or is KVM as unstable as it appears? Are you using, or planning on using, KVM in production, and how successful have you been?

  • rr.com appended to URL and I don't know why

    - by Steph
    I've been having some pretty bad and intermittent internet connectivity issues. I keep getting timeouts on my browsers, or what appears to be timeouts on my browsers. In Chrome it's generally error 21. FF it times out. And so on. While this is happening, I can go into the command line and ping or traceroute the same domain and it works fine. I use my cellphone on the same network and it's fine connecting to the same domain. And when it fails, it's all domains that are down in all browsers, chrome, FF, etc. I also noticed that when I try to connect to 192.168.1.1 it says in chrome did you mean www.192.168.1.1rr.com but when I enter https://192.168.1.1 it's fine. It only seems to do this in Chrome. This is making me think I have a virus. I did some researching about something called road runner, but I can't find any related traces. I also ran a full virus scan using nod32 (eset) and nothing. Any suggestion or help would be greatly appreciated. The intermittent loss of total internet access is really annoying and I'm worried about why it's trying to append the rr.com domain in Chrome. I suspect I'm dealing with two different issues, but you never know. Also for the DNS I'm using Google's DNS servers, the famous 8.8.8.8 and 8.8.8.4

  • Why does bash sometimes think my $HOME isn't the correct directory?

    - by Adam Yanalunas
    Like the title says it seems that bash sometimes misidentifies my $HOME. This cropped up after a seemingly unique series of events that I will now replay in broad strokes. Running OS X 10.6 with normal, local account Work binds my account to Active Directory Much time passes with no issues Set up rvm to manage Ruby installs (this becomes important later) Upgraded to OS X 10.7 a few days ago After successful install, attempted to log in, was presented with "Must reset password" dialog that never allowed a password to be reset. Would simply shake the box after new password was entered. Much googling was done. Much more googling was done. Swearing was had. Logged in as root, created new account, set as admin, deleted /Users/[new account], renamed /Users/[old account] to /Users/[new account] Logged out of root, logged into new account with no issues After OS X asking for a my account password a few times to update Keychain and other system-level stuff it was back to business as usual. Opened Terminal, cd to project folder, tried "rails server" and was presented with: /usr/local/lib/ruby/1.9.1/rubygems/dependency.rb:247:in to_specs': Could not find rails (>= 0) amongst [] (Gem::LoadError) from /usr/local/lib/ruby/1.9.1/rubygems/dependency.rb:256:into_spec' from /usr/local/lib/ruby/1.9.1/rubygems.rb:1210:in gem' from /usr/local/bin/rails:18:in' Ran through a few exercises, decided to rm -rf ~/.rvm and reinstall. Running a --trace on the rvm installer shows it dies on this line: mkdir: /Users/[old account]: Permission denied Scrolling back through the --trace log I see many more mentions of /Users/[old account]. When inspect the install script the offending line is looking at "${HOME}/.rvm" as it tries to run the mkdir. To my confusion I also see mentions of /Users/[new account] in the log. I've tried exporting a new HOME in my .bash_profile to no luck. Can anyone guess why /Users/[old account] would still be kicking around?
