Back at University

Wednesday, March 10th, 2010

Today, seeing that I haven’t done so for a while now, comes an update on my life.

I’ve just started my second year at university. My degree is supposed to be three years long, but I’ll stretch it out to three and a half because I failed stuff bigger is better. I’m still doing computing. This year comes one of the units I’ve eagerly anticipated: Algorithms. It’s programming in C, finally, after a year of Java. Also comes a not-so anticipated unit, ICT Project Management. It’s as dull as it sounds.

I’m not really sure why I’m at university. Mostly just because I can’t figure out anything else worth doing. I could go get a job, but having done that before, university seems much easier. I enjoy playing around with computers and programming, but I’m not quite confident that I really want a job as a programmer… I should probably figure that out soonish.

After resigning from Principal Computers again before I left to move to Berlin in July last year (which I ended up not doing, sadly enough), I’m now back there working Saturdays again. And I still jump every time the phone rings. Talk about Pavlov’s dog.

I’ve started playing around with Cisco networking gear again. This time I’ve got a 3550 switch, which strangely enough is more of a 24-port router than a switch. It can do some weird and wonderful things. I can’t wait to do the networking unit at university.

I Rolled Over

Thursday, November 26th, 2009

In follow up to my post about the different mobile phone providers in Australia, I’d like to share with you what I ended up doing about my overpriced phone account. To sum up the previous post, I wanted a new post-paid phone plan that cost less than my existing Telstra pre-paid plan (about $30-$50 AUD a month).

I ended up deciding to go with Virgin Mobile, since they seemed to offer the best deal overall. I chose the $25/mo Rollover Caps Plus, which includes $60 worth of calls and 300MB of Internet data.

Although I was originally planning to get a phone with the plan (probably a Nokia 6220 or N79), I ended up not doing this for three reasons. The first is that I get $10 extra call credit a month if I don’t get a phone. The second is that the phone I really want (an HTC Touch Pro2) isn’t available through Virgin Mobile, and I really like this phone. Looking at it causes drooling. The third and final reason is that the plan then has no contract length, I can leave at any time, instead of being locked in for 24 months. This does however mean I don’t get to take advantage of the 4000 bonus Velocity points offer.

I’ll reserve judgement on Virgin until I’ve used them more, but so far I have nothing major to report. The order process was moderately painless, as was the activation process (though they could improve it by marking which of the fields on the form where optional or not). I also transferred across my old mobile phone number to the new plan. This was supposed to take ‘up to three hours’. It actually took longer.

So far I’m liking Virgin. I’ll let you know if anything bad happens.

My First Coppermine CPU

Wednesday, April 29th, 2009

Yesterday evening in the mail I received, amongst a whole package of computer junk I didn’t really want, a couple of socket 370 CPUs. Four of them, to be exact. One is a Pentium III Coppermine CPU proper (an SL52R), the others are Celerons of various speeds.

You’ll notice that the SL52R is the same sSpec I was raving on about in my last post on this subject. So why did I rush out and buy one? Because to me, it has beautiful proportions. 1GHz is a nice round number. In my opinion the amount of cache is a nicer number than any other amount (256KiB instead of the 128KiB found in the Celerons and some Pentium IIIs), and the core voltage is nicer (1.75V). I would have preferred a 100MHz bus speed (instead of 133MHz), since that’s a nice round number, but you can’t have everything. Plus, a 133MHz bus does go a lot faster.

Unfortunately the picture isn’t mine; my digital camera has decided not to work in the cold this morning.

Collecting Coppermines

Thursday, April 23rd, 2009

I’ve decided to start a new collection. I used to collect Coca-Cola merchandise, but lately I haven’t found much worth buying. It’s also not especially geeky. So, I’m going to start collecting Intel Pentium III ‘Coppermine’ CPUs. I don’t have an exact figure on how many to collect there are, but my guess (based on perusal of Wikipedia and Intel’s site) is around 40-50.

Luckily for the collector, each Intel CPU has written on it something called an sSpec, which is a five-digit code (such as SL52R) that uniquely identifies each class of chip. For instance, the SL52R is a 1GHz Pentium III Coppermine with 256KiB of L2 Cache and a FSB speed of 133MHz.

As with any collection, there is a bit of a challenge with some rarer items. For this collection, my hope is to get my hands on one of the recalled 1.13GHz chips produced in 2001. They were recalled due to being completely awful and crashing all the time, so finding one might be difficult.

For me, the Coppermine core represents a pinnacle in x86 micro-architecture design. After the Coppermine and Tualitin core designs (both based on Intel’s P6 micro-architecture), Intel decided to up the ante with the Netburst micro-architecture. Netburst, used for about 4 years in the Pentium 4 series, was widely known for producing more heat than a 2-bar radiator. Indeed, when Intel went back to design the Pentium M and Core 2 CPUs, they based them off the P6 micro-architecture.

I truly believe that computers today don’t need half the power they have. Recently I tried BeOS, an operating system that hasn’t even existed for most of a decade. That ran fine on hardware half as powerful as a Coppermine CPU. It could do email (quite nicely, too), web browsing (with Flash), an office suite is available, all the usual productivity applications. But, it didn’t consume 6GB of hard drive space to do so, didn’t need 1GB of RAM (the virtual machine running it uses about half of it’s 128MB allocation), and didn’t need a 2GHz processor (these are rough installation specs for Windows Vista). It’s starting to become more and more clear to me that we are just wasting so much time, money and energy on doing things that don’t need to be done, like Aero.

So where was I? Oh yeah, bidding on old CPUs.

Trip to Berlin: Part Four

Monday, March 2nd, 2009

This is part four of my trip to Berlin. For part three, click here. This is the wrap-up of the trip.

Firstly though, the trip home. It was a bog standard 40 hour plane trip, with the only two things of note the really nice girl I met in Singapore airport, and the delay on the last leg. Just after landing into Singapore airport for refuelling and so on, a girl (well, woman, about 25 or so) came up to me and asked if she could follow me because she didn’t understand what she was supposed to be doing (and I must admit, it was confusing). I said yes, and so together we trundled off the plane, looked lost in the middle of a big hall full of shops and no chairs, and then back into the gate through security. We talked, mostly about the country we were from (in my case, Australia, in hers, Serbia). She was travelling to Melbourne to meet her aunts and the rest of her extended family.

The Qantas flight from Melbourne to Hobart was delayed by the fact that the controls for the air conditioning in the cockpit weren’t working. As the pilot said, “we don’t care, but it’s not legal to fly”. The flight time from Melbourne to Hobart is 65 minutes, and we spent almost that much time in the plane on the ground. Apart from those things, and the crappy reruns on the in-flight “entertainment”, it was all fairly normal.

There are a lot of differences between Tasmania and Berlin that I’ve noticed. The first difference was in the public transport system. In Berlin, it’s functional. The trains and buses run perfectly on time at predictable intervals (3 minutes past the hour, 23 minutes past the hour, 43 minutes past the hour and so on for all of them), and are clean and always large enough. They only service the areas where it is profitable to run (not having bus stops and routes in the middle of nowhere). Compare that to Tasmania, where buses come at random times, don’t run near enough in peak hour times, and services areas where there is obviously no profit, which doesn’t help the bottom line, degrading central city performance.

The other huge difference was when talking about buildings. The whole of Australia has had an architectural history of just over 200 years. In Berlin, a house can be “only” 100 years old. In Australia, a 100 year old house is covered in protection acts. They also have a lot of efficient heating, solar panels on a significant portion of rooftops, and double glazing is everywhere (even on some of the trains, as far as my bad eyesight could tell). In addition, recycling was a lot better organised than in Tasmania: bins in the street were organised into 4 sections for rubbish, glass, packaging and paper. A big difference from a single bin for “rubbish”, into which is thrown everything under the sun.

I’ve tried a few new foods too. Sauerkraut was one that when placed in front of me I was a bit skeptical of, though is actually rather nice (it basically tastes like less-harsh vinegar). I’ve tried cherry-banana flavoured yoghurt and cherry-banana yoghurt soft drink, neither of which were very nice. For breakfast, new items included chocolate-covered muesli and scrambled egg spread (bought in jars from the supermarket). Last item of note was the large pretzel, which tastes exactly the same as the small pretzel I am used to. Meal structure was different too. Although occasionally using the large evening meal structure, most of the time it was a smaller evening meal and a larger lunchtime meal (which I quite enjoyed).

Overall, my trip to Berlin was brilliant. Since July last year I’ve been talking to Stephanie online through IRC, MSN, and eventually Skype, and the chance to meet her in real life was awesome (so much so, I can’t even think of decent words). As soon as I can afford to do so I’m going back there for another trip. I’ll make an effort to try and see a bit more of Germany, perhaps staying a bit longer to do so. I’ve convinced Stephanie to visit Tasmania in July, so that should be interesting too.
