Discussions: Hacker News (195 points, 51 comments), Reddit r/Python (140 points, 18 comments) If you’re planning to learn data analysis, machine learning, or data science tools in python, you’re most likely going to be using the wonderful pandas library. Pandas is an open source library for data manipulation and…
I recently did a corporate TLA+ workshop and some people asked what TLA+ specs look like in practice. If you looked at the most common public examples, you’d probably come away thinking that people only used it for critical consensus algorithms. This is a problem for two reasons: first, it makes it harder to learn…
Introduction to the Rust language, standard library and ecosystem
I have recently been talking at small and mid-size companies, sharing engineering best practices I see us use at Uber, which I would recommend any tech company adopt as they are growing. The one topic that gets both the most raised eyebrows, as well the most "aha!" moments is
A guide to all the Magic Methods in Python
It’s not often I am able to write a patch that not only reduces memory usage, but increases speed as well. Usually I find myself trading memory for speed, so it’s a real treat when I can improve both in one patch. Today I want to talk about the patch I submitted to Ruby in this ticket. It decreases “after boot” memory…
For the system at work, I am on call one week every seven weeks. For most of the past ten years, I have been on organized on call rotations for the systems I have been developing. I think being on …
The Personal blog and musings of Chris Penner, a designer, developer and future opsimath.
With OTP-21 came a new logging library in Erlang called logger . It comes as an attempt to offer a built-in alternative to long successful projects such as lager , which have seen years of battle testing and tweaking for performance. I've seen few articles written about the new logger and what it can do, so I've…
Update 28 Feb 2019: I added a new blog post with a slide deck containing the presentation I did for PyData Montreal. Introduction Short intro to Python extension objects in C/C++ Zero-copy PyTorch Tensor to Numpy and vice-versa Tensor Storage Shared Memory DLPack: a hope for the Deep Learning frameworks Babel…
The blog of Seva Zaikov
I want to say a few words on how I write Haskell as of 2017. Before I go on, I want to make very clear: this is neither a style recommen...
I promised two things when I did the closing keynote at RustConf 2018:
Check out how you can use the proc filesystem to retrieve the kernel stack trace of a given process
In this post I will describe the differences between functions and coroutines and provide a bit of theory about the operations they support. The aim of this post is introduce some foundational concepts that will help frame the way you think about C++ Coroutines.
What would the world look like if there were only 16 colors? I use k-d trees to perform nearest neighbor search to find out.
Monads have exerted a curious fascination on programmers who turn to Haskell. The incomprehension of the newbies is matched in intensity onl...
My friend Clift Norris has identified a fundamental constant that I call Norris’ number, the average amount of code an untrained programmer can write before he or she hits a wall. Clift estimates this as 1,500 lines. Beyond that the code becomes so tangled that the author cannot debug or modify it without herculean…
The Embedded Design principle, Jimmy Koppel's favorite principle for code quality, shown via caching code that looks fine but invites bugs.
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
One of my tasks (as GCC maintainer of the inter-procedural optimization framework) is to make sure that it works well with real world progra...
I’m building a toy HTML rendering engine, and I think you should too. This is the first in a series of articles:
Covers general elements of computer hardware useful to know before reading the rest of the tutorials
Why Go’s stability and simple deployments is a good fit for a serverless environment.
