Fountain of Youth – the two month update

December 26, 2016

Today it’s exactly two months since I started on my “Elysium Basis” regime. Since quite a few of my friends have asked me to write an update on my thoughts about it – here it is.

I’m still of the opinion that I have more energy. I’m also confident in the “smoother skin” effect, although I’m unsure as to whether it’s because it actually is or if I just, for some reason, experience it to be.

Just as before I’ve stayed away from researching what effects I should/could expect, only looking them up once I’ve noticed a change to see if others might’ve as well. And so the third thing I’ve noticed so far is …

Alright. Before I write this I need to make a disclaimer: The effect is very slight – I do not think it will become noticeable to anyone but myself. I’d hate for anyone I know to rush out and by these supplements just because of this blog post, so please, don’t.

With that said, I seem to have some hair regrowth where the hairline has receded over the last decade. Some. A little. Most likely not noticeable if you don’t, like me, see my face in the mirror every day.

Now on to the negatives, if they are. I think my energy levels are lower than what they were a few weeks ago. I also have some “body ache”. I’ve seen others claim that this could happen if you have a methylation pathway problem, and indeed I do. Thanks to “DNA-testing” (SNP, through 23andme and Genetic Genie) I know that I have homozygote mutations affecting my methylation. I’m not sure what to make of this, currently I’m waiting to see if it gets better/worse. Since I suffer from SAD I also know better than to make too much about what I feel during the darkest months of the year (I’m no longer on SSRIs as described in that post).

tl;dr: I’m still taking NR+Pterostilbene, and will continue to do so for the moment.

Fountain of youth

November 3, 2016

“it’s better to burn out than to fade away”

(From Neil Young’s My My, Hey Hey – and known for being quoted by Kurt Cobain in his suicide note)

I remember my teenage years well. I also remember voicing the opinion above, along with other things along the lines of “life ends at 30”.

I’m 42, almost to the day. I have no intention whatsoever of fading away. I consider myself a transhumanist, and I spent some time being a board member of the Swedish subcategory of Humanity+. I subscribe to the idea of aging being just another disease we haven’t cured yet, and I eagerly follow the current state of research on the subject.

One development in particular, popularised by the company Elysium, is a combination of substances that counteracts one of the possible sources of a lot of age related problems, the declining quality of communication between our cell nucleus and the mitochondria that powers it. The list of things this affects (effects, even) is quite long – and for quite some time now there have been promising tests on yeasts and mice on how to counteract this decline, in effect boosting the levels back to where they were when we were younger.

A few weeks ago the results of the first clinical human tests were published, and I am since five days on the same formula as Elysium sells under the brand Elysium Basis. It consists of 250mg of Nicotinamide Riboside, taken together with 50mg of Pterostilbene, once a day.


… and I’m quite stunned, at the moment. I’ve carefully avoided reading too much about what effects I should experience, instead going at it with the outset of trying to see what my general experience of a month’s usage would feel like compared with before. I know all too well how dangerous expectations (and the placebo effect) can be when trying to evaluate something like this.

However, even after just a few days one effect stands out so clearly that I have no doubts whatsoever as to its existence. My general energy levels are up, way up. This applies to everything from feeling more awake directly in the morning, to walking at a very brisk pace to the bus station without feeling the slightest need to increase my rate of breathing, to working through the day and yet being fully energetic when coming home to play with my children in the evening. This does not in any way feel artificial (like you would get from Modafinil, for example), I just feel … more capable.

(Another possible effect, although I only noticed it a day ago, is that my skin feels … smoother, softer. Like after having used a facial cream after shaving. I’ll have to get back on how certain I am of this later)

So why am I taking these supplements? Is this just a case of death anxiety?

Well, I don’t think so. I do however know both from my immediate family members’ medical history, as well as from DNA testing, that I would be wise to take care of a few things that otherwise could become issues. I would consider right about now to be a suitable point in time to start making sure that I will keep my health into my 50’s, 60’s,…, 100’s.

Increased cardiovascular health, better neuro protection and lowered blood sugar levels is what I’m aiming for. Live long and prosper. One (two) pills a day.

Mega STE 1.44 HD floppy, FPU, fan and RTC upgrades

July 14, 2016

A few weeks ago I acquired a computer I never had the chance to play around with when it was new, an Atari Mega STE. It’s the culmination of Atari’s 16 bit line of computers, very compatible with the ST(E) range yet much more expandable, usually coming with a SCSI adapter and HD (1.44MB) floppy support. Besides the expandability, it can run at 16Mhz, with cache, compared to 8MHz for the rest of the ST(E) computers. It also has a socket for a 68881/68882 FPU.

However, a few very early Mega STEs didn’t come with 1.44MB floppy support, and there aren’t really any Atari dealers left if you want to sort that out – or for that matter add the logic chip needed for the FPU. So, during the last few weeks, I’ve sorted out what needed to be done to get the machine “up to spec”.

1) I found a wonderful guide over at Dbug’s site on replacing the (VERY LOUD!) PSU fan with something almost completely silent.

2) I realized the mythical Epson 340 floppy drive (Atari’s HD drive of choice) was also sold under the HP brand as Hewlett Packard D2035-60011, and snagged two quite cheaply off Ebay. The big benefit of using the Epson is that you can transplant the eject button and faceplate from the old 720KB drive and thus no modification to the casing is needed.

3) After some searching I found GAL files for both 1.44MB floppy support and the FPU support, and thanks to a fellow retro computing enthusiast (hi joska) I had both chips programmed. See below for more detail.

4) I figured out that there was a cheap and easy replacement for the original RTC battery – see separate post.

5) TOS 2.06. Yes, my machine came with 2.05. This was by far the easiest part ..

I really only bought the machine to be able to test compatibility with my software, I already have both a very tricked out STE as well as a heavily upgraded Mega ST, but I’m getting to appreciate the Mega STE more for every day. Maybe I need to have three different Atari models at my desk at all times?

Additional details for the curious:

FPU upgrade. As can be seen in Atari’s official installation manual most motherboards come with a jumper W3 that should be opened when you add an FPU. My motherboard didn’t, since it’s an older revision. According to the manual there should then be a resistor on the bottom side of the motherboard that you need to remove. At first I thought mine had already been patched, since a resistor was placed in the socket topside – but due to needing to do something else on the bottom side later (see below) I found out there indeed was a resistor there as well. Remove, insert the C301903 GAL, insert FPU (a 68882 in my case), test with Gembench 4.03 and everything’s fine.



HD floppy upgrade. After purchasing the Epson 340 (HP version) and transplanting the faceplate and eject button, I replaced the C301901-001 PAL with the newly programmed C301901-002 GAL code. See Atari’s official manual for details. Naturally my motherboard was again of the very old revision indicated and there was no continuity between U7 (the CPU) pin 32 and UA2 (the GAL) pin 19. This was why I had to turn over the motherboard and make that patch. After that all that’s needed is to change dip switch number #7 to on and test the new HD floppy support. Recalling common knowledge from way back then I didn’t bother to exchange the floppy controller to the AJAX model, since it was a WD1772-0202. Other WD-models might be more of a hit’n’miss whether they can handle 16MHz or not.




How to config an Airport Extreme from Linux

June 6, 2016

This weekend is a long weekend in Sweden – and of course I’m away from home, hacking away at the infrastructure I’m far away from. During that hacking I needed to change a mapped port in my router, and suddenly realized I couldn’t. I use the latest Airport Extreme (it really has the best performance, throughput as well as wireless stability) and the only machines I remote into are Linux (Ubuntu 16.x) based.

Conundrum. To begin with I feel this is quite lazy of Apple – they have software for not only Mac and iOS but Windows as well. My previous home server was indeed a Mac (Mac Mini, 2007 model) but since Apple no longer supports it with security updates I had to change. Linux feels more future proof. But I digress.

There’s apparently an old Java based library to interface with Airport Extremes, but not only does it rely on outdated Java versions, but it’s also very limited in what configs you can change with it. The other alternative is of course to see if Wine works.

Which it does. However, I did not get it to work at all first – nothing happened after installation when I tried to run the config app. Luckily someone else had already figured out that if you’re on 64-bit (and let’s face it, we all are today) you need to explicitly use Wine in 32-bit mode for the Airport Extreme config application to work.

Tada! Port mapping changed.

Overscan and sync scrolling

December 23, 2015

This last weekend me and many others were participating at the third incarnation of the STNICCC Atari ST conference. The first and original one was held in 1990 – where sadly I didn’t attend – and the second one was held as a reunion in the year 2000. Back then they joked about meeting up again in the far far away future of 2015.

… and that happened. Me and two others from my old demo crew had written a brand new demo that we showed at the demo competition, and additionally I had been asked by the organizer to do a talk on the latest findings with regards to two of the Atari ST’s more magical demo tricks – overscan and sync scroll.

The talk was recorded, and I’ve uploaded a version where I’ve tried to clean up the audio to Youtube. My slides (even the final version which I was unable to use during the presentation) can be found in the video description.


update 2015-12-31: I mention in the talk that I will release source code showing how you can detect the wakestates yourself. Now done. Pre-built binaries here and code on Github.

Atari ST chiptune plugin for VLC

October 13, 2015

update 2018-02-09: VLC 3.0 has just been released. Here’s a compatible version of the plugin (same source revision as before).

update 2017-03-18: Link updated with fresh build (VLC 2.x).

A few weeks ago I spent some time with the excellent sc68 software written by Benjamin Gérard (Ben/Overlanders). It’s a suite of software that can faithfully reproduce the workings of the YM2149 sound chip in the Atari ST and convert/play songs made for it. Additionally, which was the reason I took a look at it, Ben had made a VLC compatible plugin.

Since the Mac sorely lacks a competent playlist capable Atari ST music player (XSC doesn’t do playlists, Audio Overload isn’t fully compatible) I was really interested to see if the *nix support in sc68 was enough for me to be able to compile a working plugin for OS X as well.

It was. Enjoy. (I am! Thanks Ben :))


Atari ST picture conversion

August 11, 2015

It’s somewhat easy finding modern software able to read ancient data formats (note, “somewhat”). It’s often more difficult finding the opposite – conversion from modern formats to older ones.

When I’ve wanted to edit graphics using modern software (GIMP) and convert it to Atari ST I’ve so far used the excellent Netpbm package. The steps have involved converting my image in GIMP to use a colormap of suitable size, save the image as a .ppm file and then use ppmtopi1 to (finally) get an Atari ST compatible low resolution image in “Degas” format, a popular image editor back then.

This weekend I grew somewhat tired at all those steps – and additionally I wanted to convert an image to the Atari ST medium resolution format (.pi2). There’s no such application in the Netpbm suite.

It’s not completely plug’n’play, but here’s a link to PNGconv, a project I just published to Github. It’s a Java program that takes any input format Java understands (JPG, BMP, PNG, GIF .. ) and outputs as Atari ST low/medium/high (.pi1/.pi2/.pi3).

I’m probably the only one who’s ever going to use it, but you know what they say about programmers. We’ll happily spend hours now making sure we’re spending “less” hours somewhere down the road ;)
