Before jumping into books like DDIA or Database Internals, it helps to understand the systems layer these designs are built on. A lot of the design of such data-intensive systems is based on virtual memory: page tables, page faults, mmap, the page cache, swapping, NUMA

These days whenever I need a database I reach out for sqlite that comes preinstalled with most Linux. But most Unix systems have always shipped with a (non-relational) database library called dbm. It was written by Ken Thompson in 1979 and has shipped with all Unix and Unix like systems ever since. It is a simple C based library to read/write key-value pairs. Under the hood it uses a hash-based index and a binary file format. When BSD was being opensourced, they rewrote it and also added b-tree indexing. This later became Berkely DB.

Took me almost a month, but it’s finally done. I completely rewrote the first chapter of linux-insides about the Linux kernel initialization process. Now it should be aligned with modern kernels (up to master). github.com/0xAX/linux-ins…

I've been looking into autograd internals of Pytorch. While I was aware of how backward mode autodiff works, I didn't know there was also forward mode autodiff. I had to read up on that. There is a very comprehensive article from an MIT course on that, I highly recommend it.

This year I'm starting a habit of working on a book every day. I have to write at least a paragraph for it to count. (I set a small daily goal to make it RIDICULOUS for me to skip it.) I'm 15 days in. The progress accumulates fast!

Python has a "suppress" decorator in contextlib, which catches and ignores exceptions of a given type. I didn't use this for the longest time. It felt like an import to do something so trivial. I didn't care too much about saving two lines. Lately though, I prefer it. Not for saving lines, but because it is self documenting. The "suppress" is clearer when scanning code. This can get lost in your mind's eye when scanning code: try: file.write(...) except OSError: pass This feels more explicit, and easier to read at-a-glance with suppress(OSError): file.write(...) This tweet brought to you from the "last humans still writing code" generation.

You can use the module `json` to read and write data in the JSON format, which is very suitable to represent the most common Python built-in types: - lists - dictionaries - strings - integers - floats - Booleans.
