aristidb··on My God, it's full of yaks
Nix supports CMake fine. In my experience adding new packages is not too hard as long as they're not GnuCash 2.6 ;)

Any change will lead to a new output folder, there is no option of reusing them.

Why not just give it a try in VirtualBox to see for yourself how far along it is?

aristidb··on Libdill: Structured concurrency in C
If you can use C++, give Intel TBB a try. It has a lot of structured primitives but still makes it easy to just parallelize a for loop.
aristidb··on Ubuntu on Windows
Mathematica at least has a Linux version. :-)
aristidb··on The Deadly Consequences of Solitary with a Cellmate
One quote stuck with me: “But it’s a tough place to do time. People that say cons have it easy, they ain’t never been in Menard.”

Not an American, but between saying that cons have it easy and the fact of mass incarceration in the first place, it seems that there's a certain mercilessness in American culture.

aristidb··on How FPGAs work, and why you'll buy one (2013)
Intel and NVidia also sell chips in this price range.

http://ark.intel.com/products/84685/Intel-Xeon-Processor-E7-... http://www.amazon.com/Nvidia-Accelerator-passive-cooling-900...

Now, I guess you can decent performance out of cheaper chips already, but paying $5000 for an Intel CPU is hardly rare.

aristidb··on 'Flash Boys' Exchange Isn't About the Little Guy
He's probably the only journalist who can make the topic of bond market liquidity _funny_. slight hyperbole
aristidb··on IRCv3
Click "Load more backlog" and you will see the shared chat history. You can also download your chat history as a ZIP file, I think.
aristidb··on How technological innovation can massively reduce the cost of living
While reading the article, another possibility for reducing the cost of housing crossed my mind: Ways to make small living spaces more livable. Most of the cost of housing is land, and living in cheaper places is not that desirable - young people especially prefer to live in cities.

So I'm not sure what exactly is the best way for making small living spaces more livable. Maybe convenient+cheap laundry services to eliminate the bulk of washing machine & dryer?

aristidb··on Zopfli Optimization: Literally Free Bandwidth
Löve is not a German or Swiss German word, so the umlaut is simply gratuitious.

(Other languages such as Dutch or French use diacritics to mark a vowel as not-dipthongised, but that doesn't apply here either.)

aristidb··on Japan Is Obsessed with Kentucky Fried Chicken on Christmas (2012)
It appears Christmas cakes are not just a thing in Japan and China: https://en.wikipedia.org/wiki/Christmas_cake - and then there's some other delicious cake-like things: https://en.wikipedia.org/wiki/Stollen

Pudding however, now THAT is a weird Christmas tradition :)

aristidb··on ZPAQ: Incremental Journaling Backup Utility and Archiver
It also deduplicates based on a rolling checksum (similar to rsync). Pretty cool archiver.
aristidb··on WebGL water scene
Smooth on my Intel (HD Graphics 5500 / Broadwell, 2015) graphics. Nvidia's GTS 450 is 5 years old, so I don't think "we are some ways away" is necessarily true, but it is of course still very wasteful.
aristidb··on Intel's 72-Core “Knight's Landing” Xeon Phi Chip Cleared for Takeoff
They even have some interesting tools, but should IMHO invest more in them:

aristidb··on Packet copies: Expensive or cheap?
There is a technology that allows incoming I/O data to be put directly into cache. Pretty useful! :)

I think this is the original introduction: http://web.stanford.edu/group/comparch/papers/huggahalli05.p...

aristidb··on Uber Using Driver Phones as a Backup Datacenter
Parent got downvoted, but I think it's a legitimate concern: refusing people rides because for whatever reason (old phone, poor / expensive Internet connectivity) they can't update the app is problematic.
aristidb··on Social Anxiety
According to Wiktionary, anxiety comes from Latin "ango" ("to anger" - which also has the same root!), which in turns comes from Proto-Indo-European "*h₂enǵʰ". Closely related German words are "eng" (narrow) and "Angst" (anxiety).
aristidb··on DocStore: Document Database for MySQL at Facebook [pdf]
The question at the end was always there.
aristidb··on DocStore: Document Database for MySQL at Facebook [pdf]
If you're not stuck with a huge MySQL legacy installation, Postgresql 9.4's JSONB + json_path_ops index queries seem neater. Or am I missing something?
aristidb··on Interviewing for a JavaScript Job
I read this as a parable about abstracting & decomposing problems, and how lazy evaluation makes it easier. Also, about how you can write Haskell in Javascript.
aristidb··on Coinbase – Exchange API
Nice to have a ASCII-based REST API, but they should also add a proper binary protocol, which does not involve HTTP. Mainly to reduce parsing and encoding times.

(This is my personal and not my employer's opinion.)

aristidb··on Zstandard – Fast and efficient compression algorithm
Zstd and LZ4 look amazing. Here's another compressor I really like: http://mattmahoney.net/dc/zpaq.html
aristidb··on A Case Study of Toyota Unintended Acceleration and Software Safety
I'm not really a fan of MISRA-C or V process and stuff like that, but the quality of the source code and process is truly appalling if these slides are right... tens of thousands of global variables, no bug tracking and so on and so on.

I really hope they improved since then, for the sake of anybody driving a Toyota.

aristidb··on Ori File System
This is pretty cool stuff, but when I tried it in mid-2014 (release 0.8.1), there were stability issues with orifs, and the user interface was rather confusing. Quite possibly these issues are resolved now, as I see there have been new commits again from October onwards.
aristidb··on C++ Filesystem Technical Specification approved by ISO
I think for most programs, path manipulation is fortunately not in the performance-critical parts.
aristidb··on Why the global financial system is about to collapse (2006)
So I first thought this article might predict reasons for the "Great Recession" that would come a year or two later, but nope.

"Spontaneous remonetization of Gold" combined with an erosion of the dollar... While the gold price is somewhat higher than in 2006, the dollar has hardly been eroded with inflation, quite the opposite: recent years are marked by below-average inflation around the world. Long-term interest rates are at record lows, nominal and real.

aristidb··on Intel’s e-DRAM Shows Up in the Wild
This is Crystalwell, right? Which is shipping in some laptops to power the embedded graphics.
aristidb··on Workers in Silicon Valley Weigh in on Obama’s Immigration Order
The going rate being $9000/mo for an intern?
aristidb··on What sort of allocation rates can servers handle?
What other allocation rates would you immediately think of? Of course allocation rate can mean other things, but memory allocation was the first I thought of.
aristidb··on Sendmail removed from OpenBSD base
OpenSMTPD is ridiculously pleasant to configure, without sacrificing features like "I don't want my password in the configuration file".
aristidb··on Git pretty
There should be a section for git filter-branch.
