Rabid RAM Rant


Saturday, January 27th, 2007

Notebook RAM comes in various form factors, but the basic standard (which Powerbooks use) is called “SODIMM”. RAM also comes in various speeds; PC-2700 (also called DDR333) and PC-4200 (also called DDR533 or DDR2). All this I have known.

I am the proud owner of a new 1Gb PC-4200 SODIMM. Currently my Powerbook contains 256Mb of RAM soldered onto the motherboard (wonderful design decision Apple, thankyou!), and a 256Mb PC-2700 SODIMM that I installed when I bought it.

I have now learnt (by bitter experience) that a PC-4200 SODIMM is not the same shape as a PC-2700 SODIMM. Oh, yes, they have the same, ahem, “form factor”, but the little slot in the PCB that aligns the pins with the motherboard is in a different place. Out by a good 3mm, I’d say. Not sure how “form factor” is defined, but it obviously doesn’t mean “specific enough to be able to buy RAM according to it”. I have since found an Apple document (down the ladder to the basement, with a torch, behind a sign saying “Beware of the leopard”) that says that 12″ Powerbook G4 (the 1.33GHz processor type, but without Gigabit ethernet - man, how many models are there??) takes PC-2700 RAM. I guess this implies, although doesn’t explicitly state, that PC-4200 RAM is not OK.

You may let your imagination run wild when imagining my frustration. I guess I shall just put this SODIMM back on eBay, and start bidding for another one…

January is anathema to relationships.

… and that’s all I’m going to say on that topic.

Seasons greetings and all that

Here’s a belated Christmas present to any readers… a new entry. I believe I may be outdoing my previous achievements at non-updating. In my defence, since my last entry my time has been almost continuously filled with uni work, and I can’t imagine many of you would find long entries about my studies scintillatingly engaging.

But given the opportunity of the Christmas break, there are a few things I should record. Not least of course, Christmas. Saarbrücken had its version of a Christkindlmarkt throughout December, and a less-kitch more-craft Weinachtsmarkt on the first weekend. On the weekend of the 16th/17th, L trained up from her exchange in Lyon to visit, and on the Sunday we went to Strasbourg to be tourists (and investigate the sprawling Marche du Noel). Photos (naturally) at the usual place.

And then on the 22nd, lectures finished for two weeks, giving me (or so I thought) some precious time to recover from the hard work, and an opportunity to get a head start on a few assignments before lectures begin again. Not so. It seems all our lecturers also saw this as an opportunity to do more work before lectures begin again, and dealt out assignments correspondingly. But I’m not writing to complain about my work… I did after all get a bit of a break. After opening all the Christmas mail on the 22nd, R and I caught a train to some of my relatives for 4 days of Christmas food, relaxing, a little laid-back sightseeing and more Christmas food; and following this we moved on to Berlin to visit J and U (and family), see some of the sights (R had never been) and to celebrate New Years Eve.

We were greeted in Berlin with a layer of fresh snow, and some flakes still gently falling from the sky… perhaps not strictly speaking a “White Christmas”, but certainly better than nothing! After that first day though the snow melted away and the weather became a bit more mild (give or take some rain), which we were quite glad of during our sightseeing.

Having weighed up the excitement of the Brandenburger Tor party against the prospect of being crammed into the “Party Meile” with one million other people, we decided to wander past the Party Meile early-ish in the evening to see how it was, and make a last-minute decision. At 7:30 there were no real crowds to speak of (at least, nothing unpleasant), three stages with live music and a festival atmosphere (complete with blinking party hats) in between, so we determined to come back later on (since the prospect of 5 hours outdoors didn’t really appeal!) Although at 10:30 there were considerably more people - in fact the Brandenburger Tor gates were closed at various points because of overcrowding - the crowd at the Siegessäule end was quite bearable, and so we got to see the famous fireworks after all. Well, the famous fireworks and lots and lots of private ones - most of them only confirming that the Australian ban on private fireworks is a very sensible idea… alcohol and gunpowder is not a good mixture! And since (in theory) fireworks weren’t allowed inside the Party Meile zone, everyone was just setting off their fireworks around the perimeter before entering the party… lighting little whirlygigs and throwing them into the bushes at the side of the road, or setting off rockets at dangerous angles… the Aussie bushfire season is bad enough, thankyou very much! (According to official reports, the fire brigade was called out 1800 times that night.)

Once again, photos where you’ve come to expect them.

On Monday lectures start again, so I fear we may be in for another little stretch of “nothing to report”. But at least y’all know I’m still alive, and still (occasionally) capable of something exciting!
