aportnoy··on Assembly Language Programming: Still Relevant Today (2015)
This is like being an architect and noticing that bricks and cement are still relevant... Of course they are!
aportnoy··on I love coding in C
Lose the leading sentence, your comment is great otherwise.
aportnoy··on I love coding in C
Isn’t this abstraction presented at the ISA level, not by C? It’s not that C isn’t close to the way hardware works, it’s that the ISA interface presented to C compiler writers isn’t close to how instructions are actually executed.
aportnoy··on Writing userspace USB drivers for abandoned devices
I think that’s what I was looking for, thank you so much! I hope not much has changed since when it was written…
aportnoy··on Writing userspace USB drivers for abandoned devices
How does one learn how to write device drivers under Linux?
aportnoy··on Ask HN: Are there books for mathematics like Feynman's lectures on physics?
Calculus by Michael Spivak
aportnoy··on Remote war is bad war
You win when the other side thinks they lost.
aportnoy··on Modern C, Second Edition
Is this a good book, can anyone comment?
aportnoy··on Show HN: Studyr – Student Planner for iOS
Is it different from iStudiez in any way? https://istudentpro.com/ios.php
aportnoy··on What's Coming in Python 3.8
Dask doesn’t support shared memory without pickling because Python doesn’t.
aportnoy··on What's Coming in Python 3.8
I’ve been waiting for this for a very long time. Thank you for mentioning this.

Would this work with e.g. large NumPy arrays?

(and this is Raymond Hettinger himself, wow)

aportnoy··on Show HN: A minimalist Mac app that helps track, allocate, and plan your time
Fantastic app, thank you for posting! Is there a way to get the current task name to show in full length in the menu bar, similar to what you have in the video? I see a truncated name instead (i.e. instead of "do task number bajillion 30:00" I see "do task num... 30:00").

aportnoy··on Liza Alert: searching missing people using machine vision
Fascinating to see a comment from one of you guys. Any interesting news/insights?
aportnoy··on Liza Alert: searching missing people using machine vision
Thank you for the correction, I always assumed it was named after Glinka.

Liza Alert is named after her: https://en.wikipedia.org/wiki/Elizaveta_Glinka

EDIT: Apparently I was wrong.

aportnoy··on Linux touchpad like a Macbook: progress and a call for help
You can use Wireshark to intercept USB traffic and see the raw packets. That’s how many device drivers are developed for Linux.
aportnoy··on How I'm able to take notes in mathematics lectures using LaTeX and Vim
Dropping a bombshell: https://github.com/brennier/quicktex
aportnoy··on Rules for Choosing Nonfiction Books
I think it's more laughable for fiction books and less laughable for nonfiction books. Nonfiction books are like tools to me: they either perform or they don't.

aportnoy··on Electron v5.0 Timeline
Slack takes 5-7 seconds to start up and connect on an ultra low latency 300 Mbit connection. I really wish there were a native app on Mac.
aportnoy··on How I negotiated a software-engineering job offer in Silicon Valley
>Late last year I interviewed at six top companies in Silicon Valley in six days, and stumbled into six job offers.

Misleading. He applied at 20 companies, interviewed at 6, got 6 offers.

aportnoy··on Every new web app at PayPal starts with TypeScript
Heh, did you mean gripe?
aportnoy··on If 5G Is So Important, Why Isn’t It Secure?
Slightly off topic, but I wonder how much net savings (% world GDP?) would we have if there was no need to secure our communications. At least some energy and time would be saved as a result, comms would be faster.
aportnoy··on Internals of PostgreSQL
This only covers one feature of SQLite, but I recommend it nonetheless: https://www.sqlite.org/queryplanner.html
aportnoy··on Ask HN: How to self-study mathematics from the undergrad through graduate level?
Start small. I would look at Stat 110 from Harvard, Strang's OCW lectures, and the intro calculus MIT course.

When you're done with that, it'll be easy to see where you want to go next.

aportnoy··on Python with a Cocoa GUI on MacOS
I had a great experience with PySide2 (aka Qt for Python), although the docs still have examples in C++ (that are supposed to be in Python) sprinkled everywhere.
