EDIT: Tonight i’ll be picking up one of my Mac Mini’s from the Datacenter to get Ubuntu 13.04 up and running! expect a full guide with drivers here shortly :)

So Ubuntu 13.04 LTS recently was released, It comes with the new 3.8.0-19 upstream of the Linux Kernel so I thought I’d check it out!

Although our patched 12.04 and 12.10 Ubuntu’s use version 3.124c of the tg3 NeXtreme drivers from Broadcom which have Mac Mini support… The version in Ubuntu 13.04 (3.128c) seems to have had this removed!

A simple run of modinfo tg3 | grep 1686 reveals sadly that support for detection of the Mac Mini Ethernet hardware seems to have been removed during 3.124 and 3.128 of the Broadcom tg3 drivers.

I’m likely to install 13.04 on a Mac Mini sometime soon so will update this post with a proper howto and any good news I encounter but I don’t think its good news…

lsmod | grep Ethernet returns
01:00.0 Ethernet controller: Broadcom Corporation Device 1686 (rev 01)

whilst modinfo tg3 | grep 1686 on our modified 12.04/12.10 machines using the NeXtreme driver from this blog returns:

alias:          pci:v000014E4d00001686sv*sd*bc*sc*i*

however on 13.04 returns nothing.

Just a quick post to say i’ve posted my first piece of code in over 5 years to GitHub. Its a clever little Objective-C iOS Category on UIViewController that seemlessly overlays a UILabel on every single view controller managed view with the class, nib or storyboard name that is used. Great for debugging old or inherited projects with minefield architectures. It uses some cool libobjc runtime techniques to accomplish this, but implementing the category is a case of dropping it into your project and Build+Go!

My Raspberry PI

Out the box the Raspberry PI comes with a ARM1176JZFS Core (armv6 with hard float aka armhf arch) running at 700 Mhz as part of the Broadcom SoC. Additionally the memory frequency is also limited. In recent firmwares however… tinkerers have had the ability to “overclock” the Raspberry PI to squeeze some extra juice out of it. Mine’s currently running at 1Ghz at a solid 48C temperature when under load. So the first question that springs to mind is… why doesn’t everyone overclock their Raspberry PI? Well… there have been (well founded) reports of SD card corruption, heat/power issues and instability. The idea of this post is to show the user how to safety squeeze every last bit, cycle and IOP out of their PI safely’ish and without being an astrophysicist. Read on for the know-how.

So… some of you may have already seen this, if you didn’t then, here it is :) its pretty cool, it works… but has one caveat… Its a TEMPORARY unlock… i.e. it will unlock your phone sure, but once your TMSI (Temporary Mobile Subscriber Identity) is refreshed, you will have to repeat the process again… in the UK and US i think this happens when you switch the phone on/off or travel over a large geographic area… however it could potentially happen whenever…

Instructions on how to unlock are after the break :)

  1. Grab your iPhone
  2. Insert a supported Sim Card… so, if your phone is locked to Tmobile, put a Tmobile sim in there Continue reading →

Hi everyone! I keep getting lots of emails from people asking where they can buy xyz to complete the tutorials and try out some of the things listed on CaptainGeek, well after I kept emailing people the same links i had a thought, why not setup an amazon affiliate store. Basically, i’ve setup a small amazon site with a small selection of products (only those used for the tutorials on this site + related ones), purchases and payments are handled by amazon, however a small percentage of the sale goes to helping fund the server this website is hosted on AT NO EXTRA COST TO YOU :) so its a win win situation, please use the links whenever you can.

Well in about 30 minutes i’m going to sit an exam in this topic, covering the Data Protection Act (1998), Human Rights Act (1988), CAN Spam Act (2003), Computer Misuse Act (1990), Freedom of Information Act (2000) + many more. The subject material is actually quite interesting and enligtening,  i can say it has actually had an affect on my business and personal practise on the Internet. I’ll let you know how it goes later on…

Did you know: if someone hacks into your company computer, not only are they guilty under the Computer Misuse Act, you are also guilty for allowing it to happen under the Data Protection Act!

Update

Well it went rather well I think, it consisted of 50% multiple choice and 50% an essay style scenario. Mainly focusing around UK law, about 25% of the module was covered in the exam; a lot of wasted revision, but on the whole i think a success! =)
