Ham Radio
Ham Radio (!)

A new hobby I started around Octoberr 2018. I was on CB radio many years ago but ham radio fulfils a more global as well as community function not only for emergemcies and events but also for general "ragchewing" around the globe. I'm aiming to pass my license in May 2019.

I bought a LG LW6510 3D LED TV recently and have taken a few photos to show some of the functionality it offers along with the LG Blu-ray player. My review is at plus.google.com/u/0/photos/112580063909169692065/albums/5....

Linux Mint 12 64-Bit Installation
Linux Mint 12 64-Bit Installation
Upgraded from 32-bit to 64-bit Linux Mint 12 today mainly because I could not access my full 4GB of RAM with the 32-bit OS.... turns out it was well worth it as my Virtualbox is faster and so are file copies at about 80MB/sec. Here are some photos to show you what the installation process looks like...
Upgrading my Samsung S4 to Android 4.3
Upgrading my Samsung S4 to Android 4.3
Process to update the Samsung S4 i9500 manually to Android 4.3 Most users will use the Kies software to update, but it could be that you want to do this manually because your update is not yet available (or you want to live on the wild side). In my case I also wanted to retain my rooted status of my phone and unfortunately the app that does the update and retaining root all in one step (Mobile ODIN) is not supporting the i9500. I downloaded the official Samsung ROM update for 4.3 for South Africa from the Sammobile site (www.sammobile.com/firmwares/). I followed the instructions at android.sc/update-samsung-galaxy-s4-i9500-with-official-a... to flash the updated ROM to my device. It rebooted fine with its original apps and files in place, along with even the Google Launcher that I had just installed a day ago. Always let the phone finish its first reboot without interruption (unless you see an error message) as the first reboot will take a little longer than normal. I followed the instructions at www.ibtimes.co.uk/articles/520949/20131110/galaxys4-i9500... to get my root access back. Only odd thing is that with KNOX now installed it warns about some low level apps being blocked for root access so I followed the tip at the bottom of the page (www.theandroidsoul.com/root-galaxy-s4-lte-i9505-on-androi...) to freeze these notifications out. Non-root users won't worry about this.
Hewlett-Packard HP-41CV
Hewlett-Packard HP-41CV
If I was asked what was my all time favourite "gadget" I would have to answer my HP-41CV calculator... not only did I have a highly portable fully programmable device but it also set me off on my IT career! Most notable is that I have sold off just about every other gadget and phone over the years but there was never any question of letting go of my trusty HP-41CV. I got this calculator when I was studying engineering at university in 1983. I seem to recall my father organising it through an uncle of mine who worked at Hewlett-Packard at the time, who got it at a staff discount for me. I was over the moon when I got this device and it really opened the world of programming for me and testing out what I could do with it. HP had a whole ecosystem of quality accessories, had the Key Note magazine that helped build the HP users community, etc. The Solution Books allowed you to type the code in yourself to add new games and functionality - this may sound elementary but is vitally important as it was essentially open source code that showed me how games and applications worked so that I could apply similar techniques in programs I designed myself. They had also standardised on RPN for calculating (which is extremely powerful) as well as various accessories which were way ahead of their time. Of course with an HP41C going to the moon at the time, that only served to further enhance its image. These calculators were drop tested 1m onto concrete and were built to really last - most are still running today after 30+ years. Yes I'm trying to source some N size batteries to start mine up but I have no doubt it will work. The career changer for me was that after university I joined the police (because back then we had to do national service in either the Defence Force or Police) and one challenge for the guys was wanting to know what shift (a morning, afternoon, night or rest day) they would be working on some future date (eg. Christmas, their birthday). So I wrote a program that would quickly work this out. Needless to say I was a big hit and the "go to" guy to find this out quickly. Later on when the Information Systems IT Unit was being formed in Cape Town the Colonel in charge of my unit called me in and said I was submit my request to go to IT as that is where my future lay.... and it all happened from there thanks largely to having a device like this. The photo album shows various accessories that I bought including extended functions modules, a rechargeable battery pack, a magnetic card reader (so save and reload programs), solutions books, manuals, and HP Key Note magazines. One extra photo is included on the excellent go41cx emulator for Android (see market.android.com/details?id=o2s.emul.hp41cx). This emulator faithfully reproduces all the functionality of the HP-41CX including add-on modules. I'm busy practising on this emulator in preparation to being able to start up my calculator soon. The original HP-41C was fully functional and could accept any additional function modules, and the HP-41CV had some extra memory built in , whilst the HP-41CX had the extra memory as well as the Time and Extra Functions modules already built in. The extra function and memory modules along with full programmable capability meant these devices were very hardy and future proof - you could spend the money as you were investing in something long term that you could extend along with your needs.
