zactato··on John Carmack on Functional Programming in C++ (2018)
Hasn’t Lisp been the language of choice for CS 101 for several decade at MIT and other universities?
zactato··on Craft using an inertial mass reduction device
I’m sorry this sounds a little like magic, I am not a physicist, but thought you couldn’t alter inertial mass
zactato··on Play Counter Strike 1.6, with full multiplayer, in the browser
Sure there were some real gun mods in doom, but the gun sprite resolution was crap, the limitations of the engine added limitations to map design and while multi-player was possible it wasn't anything like the post-quakeworld era.
zactato··on Play Counter Strike 1.6, with full multiplayer, in the browser
I remember playing one of the early CS betas as a Half-life mod in ~1999. It was such a huge leap in gameplay and style from anything else out there.

Most FPSs up to this point were SciFi based, guns like the BFG and plasma guns. Counterstrike's focus on realism really altered how you connected with the game. Columbine had happened very recently and was still very much in the zeitgeist. There was a very real cultural attack on video games as a scapegoat for the massacre.

My friends and I would build CounterStrike maps that were the layout of our highschool and would then run around and shoot each other. This was very taboo at the time. We knew that this would be interpreted as threatening by the powers-that-be at highschool, but it was exciting.

zactato··on Apple CEO Tim Cook requests and receives a 40% pay cut
Is this more aimed at Shareholder happiness or internal perception among employees?
zactato··on Capital One axes 1k tech roles
You’re looking at it all wrong, story points are a defensive tool for you the developer. It gives your team a made up unit that no one else understands.

If you told someone on Monday that a ticket takes two days they’ll ask you on Thursday why it’s not done.

Instead story points combined with team velocity give your team a sense of how much work you can commit to.

Of course we all have in our mind that a 5 point story takes a like 3 days.

If some director or product leader comes in and looks at these tickets the won’t see any time estimates on them and thus can’t hold you accountable to them. Sue they can look at your team velocity. But that’s generally a higher level moving average of several sprints.

Of course this is all imprecise and often isn’t implemented well. I’ve seen it work very well for some teams, where it gave us a good sense of our accomplishments and led to more ownership. It often doesn’t work and just adds overhead.

I’ve ditched it for my current team.

zactato··on Gptcommit: Never write a commit message again (with the help of GPT-3)
Did the OP use the tool to write his own commit messages?

A lot of the commit messages were typical and sort of redundant but this one stood out to me https://github.com/zurawiki/gptcommit/commit/82294555e7269e6...

"Add github token to address GH Workflow rate limits"

This is a good commit message, it describes a problem and a solution. I'd be very impressed if the GPTCommit tool wrote this and knew why the github token was being added.

zactato··on How 1Password is designed to keep your data safe, even in the event of a breach
I would be very impressed if the 1Password CEO released his/her encrypted vault to the public. It would be a real vote of confidence for the encryption.
zactato··on I went through a period where I loaned money to anyone that asked me
I've been following Carmack for 30 years, because of his brilliance and perspective on software. I never expected I would every feel emotionally touched by anything he said, but this was a very heartwarming story.
zactato··on UC strike energizes unprecedented national surge of unionizing academic workers
Why are the academic employees organizing under the UAW? Isn’t that for auto workers? Did they expand to embrace other workers?
zactato··on Sim Wong Hoo has died
I hope his eulogy is read by Dr Sbaitso
zactato··on U.S. moves to seize $460M Robinhood stake linked to Sam Bankman-Fried
I actually sat across the aisle from him on his way back from NYC -> SF this past week. He really didn't want to make eye contact with anyone.
zactato··on California’s population shrinks for third straight year
As a rule, we Californias refuse to acknowledge that there are any non-democrats in the state, therefore they can’t move to Florida.
zactato··on John Carmack Leaves Meta
He lives in Texas still
zactato··on Ask HN: How do I thrive in an AI dominated future?
If ChatGPT can write JIRA tickets then I will accept the robot overlords. That is a burden worth more than my humanity.
zactato··on Beyond Functional Programming: The Verse Programming Language [pdf]
Its always amazing to see Tim Sweeney's name attached to things. The first game I played of his was ZZT around ~1992. It was a basic but super cool game that featured a basic level editor!! The idea of creating levels for a game was still very novel and very exciting for 8 year old me. I would draw out levels at school and try to create them at home (with mixed success).

It's 2022 and he's still very very relevant in the gaming world. He still runs Epic, he's still publishing papers on gaming. I don't think any of the other folks from that early era of PC gaming are still relevant in the field (Carmack moved on to VR and now AGI).

zactato··on Reconstructing images a person sees via non-invasive brain scans
This is super cool, but it seems pretty far from "mind reading".

It's not reading what the person's brain is interpreting the image as, but rather what they're currently seeing. I wonder how different these signals are.

It's a pretty big difference since the only signal they're getting is what the eyes are currently seeing. Essentially they're using a $1million fMRI to poorly do the job that a $5 dollar camera could do.

This is still super cool, but not quite our wildest scifi dreams.

zactato··on What’s so great about functional programming anyway?
Obviously the best part of Functional Programming is arguing about the pedantics of whether a language or construct is actually "functional"
zactato··on Katamari Hack (2011)
Also on the Switch https://www.nintendo.com/store/products/katamari-damacy-rero...
zactato··on Lego Is Discontinuing Mindstorms
RIP My Robotics professor developed ROBOLAB with Lego + LabView. In return, Lego funded part of the robotics department. We had the most amazing Lego lab. Bins of every shape piece you could ask for. It was really a childhood dream come to life.
zactato··on Ask HN: Real-world anecdotes of MySQL at scale?
oh yeah Vitess looks slick
zactato··on Ask HN: Real-world anecdotes of MySQL at scale?
When I left Fitbit we were still using MySQL as the primary datastore for all tracker data. Admittedly only in the 10s of millions of users, but tracker data was stored at sub second precision and indefinitely. It was definitely up in the 10s or 100s of TB. Unlike most DBs it was more write heavy than read heavy.

Our scale has handled by sharding based on userId and geo. We could dynamically shift the shards when scaling the cluster up and down. I wish we had open sourced that sharding layer, it was pretty nifty.

zactato··on How to 3D-print one of the strongest stainless steels
Probably a dumb question (it’s a decade since my last materials class): why can’t you laser scinter during the printing and then heat treat in an oven to regain material properties?
zactato··on AI Seamless Texture Generator Built-In to Blender
Aren't indie games already dangerously close to the commodity space? Steam is overwhelming these days. There are dozens of games I can build bridges in or new interesting strategy games. How is any one developer supposed to capture enough market share to make any money of their work? I am worried that tools like this will just lower the barrier even more.

Maybe its a good thing because it will allow indie devs to spend less time/money on art.

zactato··on Static site hosting hurdles
I think people in the web development space will continue to understand this concept. People who are curious will learn how the internals work.

For everyone else, who cares? Search is so good that it doesn’t matter where a file lives on your device. They don’t need to understand the internals of how directories work.

Good riddance! Even though people knew how to use files and folders no one did it well. It was a mess of “new directory” and “copy of copy of essay5.doc” I’m so thankful that most folks don’t have to deal with that anymore. They can use their computers instead of fighting them.

zactato··on D2: A new declarative language to turn text into diagrams
Lucidchart has entered the chat.
zactato··on Time for Army Corps of Engineers to investigate moving water West?
It’s mostly used by agriculture. A large portion of the food you’re eating come from CA. I think there are some major crops that need to be rethought, but a broad crop failure would be pretty devastating to a lot of people in the US
zactato··on Some pits on the moon are always 63 degrees, opening up habitation possibilities
Is temperature really a big problem? It’s pretty easy to generate heat with electricity and I assume the near total lack of an atmosphere on the surface of the moon makes insulation straightforward.
zactato··on What I Learned at Clubhouse
Isn't that podcasts? There are certainly some more topic oriented podcasts, but the more popular ones are basically two famous people chatting on random subjects: eg Joe Rogan
zactato··on Volkswagen bringing back Scout brand truck as electric vehicle made in America
I hope this ends up being smaller than the F150.

I get the popularity of that form factor, but I simply don't believe that many people are hauling yards of soil or towing boats.

2 Seats + 6 Foot bed seems like a winning combination in practicality, but is quite rare in the US.
