2018
I just finished The Killing, season 3. I don’t know if the next version is available on the Apple TV. Will check.
Today I listened to an old compilation of audio track (MP3) from the Velvet that I was burning twenty years ago. At that time it was kind of my collage period and I created many CD covers and photo montages. I felt sad to learn that the Stile Project, from which I had printed one of the images, is now completely defunct and the domain name is now hosting a porn website.
I no longer have any interest in Google products, still I often hear about other abuses committed by Facebook or Microsoft, and I’m speechless, see, e.g., Tell Me Again Why You’re Still Using Windows on Irreal blog.
Interesting reading: The family history: the first genetic test, and still useful after all those years?.
Added to my reading list: Introduction to Applied Linear Algebra (PDF, 473 pp.). Note that it also comes with a Julia companion textbook. (h/t @carlcarrie)
I can’t believe how many drafts I’ve been able to keep for more than six months.

Thanks to https://archive.org, the CLRS textbook (3rd ed.) can be freely downloaded. One can also find the famous Sedgewick’s Algorithms. I found a PDF copy long ago, and it is dedicated by Simon Plouffe.
There is always something we miss. Here is a shot of those vines that cradled my childhood.

Frank Harrell started hosting his own blog several months ago, and I followed his posts once in a while, that is almost every time I see something new on Twitter. His last annoucement is about a talk he will give at the Johns Hopkins Department of Biostatistics, which appears to be a mix of his latest posts on this topic. I wish I could attend his talk as I did for his RMS workshop in Ottawa some years ago.
Please note that my last tweet or retweet is from October. Don’t expect any other news from me–I will only bookmark tweets that I found interesting while the liking option is still available. If the “like” feature is going to disappear, then it means I will definitely forget about Twitter.
SLEEF: A Vectorized Math Library.
It implements vectorized versions of all C99 real floating point math functions. It can utilize SIMD instructions of modern processors. SLEEF is designed to fully utilize SIMD computation by reducing the use of conditional branches and scatter/gather memory access.
It looks interesting even if I am not going to use it any time soon. (Other than the short vector math library available in clang).
Last episode of The Killing 2 planned for tonight.
Here is the Request Map for this website. Still a lot of external dependencies that I could get rid of.
Quick update on Stata online book. Check it on the dedicated page or on GitHub.
Want to test your competitive programming skills? Take a look at this Bachelor’s Thesis: Analysis and solution of a collection of algorithmic problems (by Rafael Eusebio López Martínez).
In competitive programming, one has to use knowledge in algorithms and data structures to find solutions to algorithmic problems, then put those a ideas into a correct computer program that solves the problem within given time and memory constraints. This activity involves learning about a wide range of complex data structures and algorithms, and many hours of training.
See also my review of the Competitive Programmer’s Handbook.
Alice in Chains, Dirt. It’s been a long time since I’ve listened to such records.
I don’t know if there’s a better solution, but this is working very well in my
case. #org
I just came across this new book: Foundations of Data Science (PDF, 479 pp.). It looks great and furthermore this is one of those rare books which provides an original approach to data science and machine learning from rigorous (mathematical) arguments. Other resources are provided in the following Twitter thread.
If you are like me a long time user of command-line tools for data munging, you will probably find some useful utilities on this post: Data Processing Resources: Command-line Interface (CLI) for CSV, TSV, JSON, and XML.
It is snowing, slowly but surely. BTW, we started watching Vikings last week as soon as we were done with The Wire (Season 1).
“The numbers 111, 222, 333, 444, 555, 666, 777, 888, and 999 are all evenly divisible by 37, leaving no remainder.” (via @pickover) Using base 10 notation, a three-digit number, say $aaa$, can be written as $100\cdots a + 10\cdot a + a = a \cdot (100 + 10 + 1) = a \cdot 111$. Clearly, 111 is a divisor of $aaa$ ($111 = 37\times 3$), but also of 222, 333, … Hence, all three-digit numbers that are multiple of 111 will fit the bill.
Welcome to season 2 of The Killing! Also, I just had to reboot my Macbook–Mojave upgrade–after 37 days uptime with the same Emacs running in the background.
Season 1 of The Killing is over. Hopefully, the next season is about to start.
Katie Melua, Ultimate Collection.
I discover Katie Melua years ago thanks to my aunt, and now I also happen to read a nice book, thanks to her again.

Remember that paper from 2012 on Julia as a Fast Dynamic Language for Technical
Computing? Now, Julia 0.6.2 is extensively described in this recent article:
Julia: Dynamism and Performance Reconciled by Design (PDF). Interestingly, Julia
relies on at least 6 different PLs. #julia

development and why the language itself continues to fascinate people. #lisp
A few months ago I read an interesting post by Tom MacWright on the raise and fall (and raise again) of AI. Now, I came across the following thread that sounds like we also need to consider RL, which I learned about twenty years ago. Go figure.
