Solving noisy iMac 27″ fans problem

Solving noisy iMac 27″ fans problem

Recently my 27″ iMac has been generating quite a bit of uncustomary fan noise – even when practically idle! After downloading and installing smcFanControl, I found out that the problem was my hard disk drive fans running at excessive speeds of 4500rpm!! If you are facing the same noise problem that I was, this is the solution: 1. Ensure that you have installed smcFanControl (freeware) 2. Launch Terminal, which is located in your Applications – Utilities folder and type this command /Applications/smcFanControl.app/Contents/Resources/smc -k F1Mx -w 2af8 This now sets your Hard Drive fan speed to 2750rpm! If you are certain that the ambient temperature is low and you aren’t running anything CPU intensive, you may want to get the noise (?)...

Etherpad Lite on Ubuntu 10.04 with Nginx reverse proxy

Etherpad Lite on Ubuntu 10.04 with Nginx reverse proxy

Etherpad Lite is an opensource web-based word processor that allows people to work together on a document in real time. When multiple people edit the same document simultaneously, changes by any individual are instantly reflected on everyone’s screen. The result is a new way to collaborate on text documents, which is particularly useful for meeting notes, drafting sessions, education, team programming, and more. People currently viewing an active pad appear in a sidebar, and each person is assigned a unique background color to track individual contributions. You can type, undo, copy, and paste without interfering with other peopleā€™s simultaneous edits to the pad. Backup copies of all saved revisions can be restored at any time. I was using a public Etherpad...

How to use Dropbox in a locked-down office network and Apple iOS apps

How to use Dropbox in a locked-down office network and Apple iOS apps

MobileMe iDisk is shutting down on 30 June 2012. Following the advice of many, I moved my files over to Dropbox instead. Unfortunately 1. Apple iOS apps such as Keynote or Pages are unable to open documents stored in Dropbox 2. My office network blocks the use of Dropbox Fortunately there is a single solution to both problems! What we need is to sign up for a FREE account at SMEStorage, which lets you utilise the space you already have with your Dropbox. And yes, you can also add any other cloud storage provider listed below too. SMEStorage has an add-on feature called CloudDav that lets us access Dropbox via WebDAV. What does it do? You can see the description below – but most important is that it allows us to access your Dropbox files in iOS apps that...

Fixing the annoying “perl: warning: Setting locale failed” error message

Fixing the annoying “perl: warning: Setting locale failed” error message

I was getting really annoyed getting these messages while managing my Debian and Ubuntu VPSes perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LANG = "en_US.utf8" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C").

Running Diablo 2 on OS X Lion

Running Diablo 2 on OS X Lion

I upgraded my Macs to OS X Lion a few days ago and have been very pleased with all the new features. But when the nephews came vistiing today and wanted to play a local LAN game of Diablo 2, all we got was … Ooops! As it turns out, Blizzard had, a few days ago, posted some information regarding OS X Lion not being able to run their classic games, including Diablo 2! Diablo 2 was released for Macs running PowerPC processors (remember: Intel Macs only stared appearing in 2006). It’s been able to run previous in Intel Macs due to the inclusion of the Rosetta translation software, but this is no longer available in OS X Lion. Thankfully, a solution exists! The first thing to do is you need to have a free Battle.net account. Create one if you don’t...

KnowledgeTree speed on VPSes

KnowledgeTree speed on VPSes

I was trying out KnowledgeTree 3.7.0.2 (Community Edition) on 3 different virtual private servers just to see how they fareĀ  with “heavy” websites, and here’s how they perform generating a page of 20 items. All VPSes are 512MB instances running on Ubuntu 10.04 LTS . APC Hosting (Virtuozzo) Request created in 17.190s Rackspace Cloud Server (Xen) Request created in 0.446s Club Uptime (OpenVZ) Request created in 0.299s The most ironic thing is that the above VPSes are listed in order of most expensive to least expensive. It seems here we do not get the best performance from the mostĀ  expensive service? In fact it performs much worse than the other two! At this point, the Rackspace offering is the most attractive with its built-in manual and...
