I might have accumulated a few too many hard drives.

Ah, damn I had forgotten you could change the geometry as well. I don't miss those times. At all.

I made a Story with my peanut butter chocolates (because I'm very happy of how these turned out ;) ). I like it. It has somewhat less details than the blog post on http://coincuisine.pasithee.fr/2016/01/11/chocolats-au-beurre-de-cacahuete-chocolates-filled-with-peanut-butter/, but as a synthetic food-porn oriented media, there's potential :)

This time, this is chocolate with lemon zest and poppy seed. Though in practice it seems we need bigger doses as I mostly don't feel them in the chocolate (except for a small aftertaste of lemon).

Also, silicon mould is less convenient than polycarbonate mould.

Digging into reddit new mobile website performance issues:
https://github.com/reddit/reddit-mobile/issues/247
Been meaning to do a performance audit of the new mobile site. I'm going to drop it right here into the ticket. I may add comments as I go along. Initial Test: Loading (total duration: 45 seconds)...

How to ray trace a blackhole, with even a bit of science in it:
http://rantonels.github.io/starless/
It's now clear I'm on a Black Hole binge (I can stop when I want, by the way). They're endlessly fascinating. My recent interest was in particular focused on simulating visualizations of the Schwarzschild geometry. I was preoccupied by the problem of generating a decent accurate representation ...

And the award for most mind-boggling compiler optimisation ever goes to ..... Matthias Grimmer and Chris Seaton!

One problem people have when trying to speed up fundamentally slow scripting languages like Python and Ruby is that because the original implementations are so lethargic, people often rewrite parts in C to try and speed core things up. But these C extensions usually just plug straight into the original interpreter, making it difficult for anyone to ever do a better engine than the original because nobody can afford to rewrite all the extensions. It's like a tarpit of slow.

From the blog post:

"Our new solution in JRuby+Truffle is pretty radical - we're going to interpret the C source code of your extension. As we'll explain, JRuby+Truffle with an interpreter for C extensions is actually faster than running compiled C extensions using MRI!"

And they aren't kidding. Rewriting from Ruby to a C extension for some image processing tasks gets a 10x speedup. Going from Ruby to JRuby+Graal+interpreted C extension gets a 35x speedup! Of course it's not really interpreting C. It's actually doing a Java-style just in time cross language profile guided compile of the C/Ruby mix, on top of the actual HotSpot JVM, meaning that amongst other tricks ... it can actually inline both languages into each other at the machine code level! And it's benefiting from the 20+ years of performance research that has gone into the JVM.

Doing whole program optimisation across a dynamic scripting language and C on top of the JVM has to be the wildest mashup of programming technologies I've seen for years. Congrats to both of these mad scientists!
Very High Performance C Extensions For JRuby+Truffle. Matthias Grimmer and Chris Seaton, 27 October 2014. Ruby and C. C extensions are a big part of the Ruby ecosystem. They allow people to write Ruby programs to include C code for a variety of purposes. They may hope to make their Ruby program ...

I haven't posted chocolate picture in a while :)

Today, I made chocolate with pistachios. I slightly roasted the pistachios in the oven, though I think they should have stayed a bit more.

I've used cocoa butter & pure cocoa powder from https://www.schwarzenbach.ch/ , an old Zurich institution for coffee and beans. Result is quite good - I quite like Schwarzenbach chocolate which is quite strong and tasty.

Also, doing the Mycryo-tempering around 35C instead of 34C seems to yield better results (less grainy aspect).

What is your end goal here, because i'm looking at your progress... and it seems clear that you could end up with world domination.

Command of the day, don't try it at home:
  dmraid -E -r /dev/sda

I was trying to install a basic ubuntu on an old (windows) PC. It was somehow not seeing /dev/sda in the installer - fdisk knew about it, but it was not an option to install on it.

I tried switching to AHCI in the bios and even nuking the beginning of the disk with dd & /dev/zero.

But it seems that there was somehow some trace of some md setup, thus hiding silently the disk from the installer. Nuking that made everything work fine from there.

Today's experiment is a bigger chocolat tablet. I've doubled the amount - so 100g cocoa buttter, 80g cocoa, 26g sugar.

There are roasted whole almonds in it - that was the reason of making a bigger tablet, so they would fit. In practice, I've used 45g of almonds, but I could have used a lot more as it holds extremely well.

I've used "vergoise" as sugar, a kind of crystallized sugar - it gives a kind of crunchy feeling which is nice (though it makes the chocolate fell less sugary overall).

Also, I've used a basic ceramic dish as mold. I had to hit it quite strongly for the chocolate to leave it, but that worked out :)

Interestingly, given that the mold was flat without any motif, we see much more how the crystallisation is not uniform - center is shiny, sides far less so.

Another attempt at chocolate. The mould once again worked perfectly - despite being hard plastic, the chocolate bars just fell from it.

Those bars have one chunk of pecan nut per element. I placed the pecan in the mould before the chocolate, so the chocolate was not able to completely go to the bottom of the mould in some places unfortunately. And the ugly thing in the top right corner probably indicates that there was some water drops that I somehow missed.

But all in all, the experiment with big nut chunks is mostly successful :)

Hey folks, I'm looking for a job.

I'm a sysadmin/programmer, with 14 years of experience. I'd like a job either in Switzerland, or one that allows me to work remotely. I do not have good German at the moment, so being able to work in English is a requirement in the short term. My CV is available here: http://diamond.ichbinn.net/priv/plus-wae5sheB/stephen-shirley-cv.txt

If you know of any jobs that might match what I'm looking for, or even companies worth considering, please let me know.

Thanks :)

Fascinating presentation on the history of the notion of API - and how subroutines came to be a thing.
Excerpt I particularly liked about Wilkes work in the beginning of the 50s:, "at the time there was no notion of backward compatibility - there was no legacy programs"

I especially liked:
"""Geeks get to spend more time hacking
─ less time talking to lawyers"""
I'm not sure whether lawyers will be very sensitive to this argument.

Introduction
Geek, software engineer, tinkering with things from linux internals to minecraft, with some amount of python, javascript and other things. Boardgaming and a fair bit of RPGs and Warhammer 40k here and there too.

My Scratchpad gives a small example of the kind of things I do.
