Today, I was trying to print something at work and found out that our old Brother MFC 8840D printer was now replaced with a Fuji-Xerox DocuCentre-II C3300. The printer comes up in the network and is successfully identified (full printer name), but the driver is not listed anywhere. At least I didn’t find one that is close to it. There is a generic option but I did not bother to try that. Instead I opted for this solution:
When `ssh-add` does not work as expected because a ‘Could not open a connection to your authentication agent.’ error comes out, this might help:
There are environment variables that needs to be set and doing the command above will essentially do just that but with far lesser key strokes. It is also easier to remember since those archaic commands and environment variables that needs to be set always escape my mind.
6th Nov 2012 is a memorable day for Ubuntu/Linux users. It is the day that Valve has started the Steam For Linux closed beta testing. For many gamers out there, casual or hardcore, I’m sure they are familiar with Steam. Who wouldn’t be? And for Linux users, particularly those who use Ubuntu, many would be delighted that Valve has released their Steam client primarily with Ubuntu support.
If you are among the countless people using Eclipse IDE as your platform for software development on Ubuntu, then you may have noticed that it does not integrate at all into the global menu on Unity. Not a deal breaker actually, right. This does not even hamper you with your work at the least. I know it doesn’t for me.
However, if you are one of those who always strive for consistency on their Ubuntu desktop, then maybe this one bothers you a bit.
Adobe Flash Settings always worked fine back when I was still using Ubuntu Natty Narwhal in that whenever a Flash application needs permission to access my laptop’s camera and microphone, I can click on the Allow/Deny options. On Ubuntu Oneiric Ocelot Flash settings is unclickable and it will eventually hang and crash whenever it asks to access the camera and microphone. I don’t know if this happens on all the sites, but on one site I’m working on, this happens all the time. The browser does not matter, at least for the ones I use. It will crash on both Firefox and Chrome.
This is a fix on how to access the files on your phone via bluetooth on Ubuntu 11.10. I found it recently when I realized that bluetooth on my laptop was not working like it did on Ubuntu 11.04. Sure, the bluetooth dongle and my phones are detected without problems. Even searching for other active bluetooth devices within range is done correctly. However, connecting to my phone on bluetooth is not working properly after it has been paired with my laptop. While I do not use bluetooth to transfer files that often – it is awfully slow – there are times when I do need it, like those instances when I forget the phone USB cable. It is during times like these when bluetooth comes in real handy.
Assuming you already have Ruby, RubyGems and MySQL installed on your system, along with the necessary development files and tools for compiling, this may help you avoid a lot of confusing errors when you are trying to set up Webistrano.
I got stuck at the part – rake db:migrate. One error would come out after another, it was overwhelming for first timers like me.
My upgrade to Ubuntu 11.10 Oneiric Ocelot had been a smooth one albeit a bit late. Originally I was going to stay with Natty Narwhal and wait for the next LTS version – 12.04 Precise Pangolin – come April this year. What with 12.04 coming up fast in a mere 3 months and all the very nice features on Unity 5.x included in it, why bother to upgrade to 11.10?
It is not often that I stumble upon a website that uses Microsoft Silverlight. I am sure there are thousands of websites that use this technology. I am aware that Netflix uses Silverlight heavily. Still, I think it is safe to say, that Silverlight is not as commonly used as Adobe Flash. So what happens when I actually find my browser at a site that uses it?
Nothing happens. That is for sure.
This is a known bug. One that has been mentioned several times on the Ubuntu and Linux Mint forums as far back as July this year, and maybe even earlier. Honestly I don’t remember this happening on my old desktop computer – Intel Core 2 CPU with a 250GT NVIDIA graphics card. Lately, I’ve been having these lock ups one too many times since I purchased my notebook barely a month ago – Intel i5 2410 with dual GPU (Intel HD Graphics and Radeon 6470M). On both desktop and notebook, I have Ubuntu 11.04 installed with the main difference being, aside from the hardware, that the notebook sports the 64-bit version to fully utilize the 8GB memory.
