robterrell··on Cosmoteer: A starship design, simulation, and battle game
Did you try doing your Rust dev on Mac? I've built Unity plugins in Rust and have been able to load and unload them without crashes, but I've only tried on a Mac.
robterrell··on Are forest fires as bad as they seem?
And, California plans controlled burns.
robterrell··on Google Doesn’t Want Staff Debating Politics at Work Anymore
...wow. Just wow.
robterrell··on Apple buys autonomous driving company Drive.ai
"The backdrop: Drive.ai's highlighter-orange vans ferried workers around a business park in Frisco, Tex., and shuttled fans in nearby Arlington to Cowboys games."

This sounds more impressive than the Cruise cars I see with one driver-engineer at the wheel. Has anyone been shuttled in one and can comment on the experience?

robterrell··on SwiftUI and Catalyst: Apple executes its invisible transition strategy
Non-PowerPC software was run in emulation: https://en.wikipedia.org/wiki/Mac_68k_emulator

But yes, Metrowerks saved their bacon by providing the only PowerPC compiler for quite a long time, IIRC.

robterrell··on Byte Magazine – Smalltalk (1981)
Byte Magazine had the best covers.

Page 98 has a fascinating Larry Tessler discussion of Smalltalk that includes a version of his "no modes" rant that later became the foundation of the Macintosh UX. It's fascinating to read in retrospect... he calls out Alan Kay's overlapping windows as de facto modes. (I'm trying to image a past where overlapping windows lost and tiled windows and virtual screens won.)

But the thing I like the most is the ability to write some code in the text editor, highlight it, and use the "do it" menu command to immediately execute it. Would be terrible for security... but I want it.

robterrell··on Air conditioner ‘in a patch’ provides portable cooling
Chops up the air molecules, you'll suffocate! https://en.wikipedia.org/wiki/Fan_death
robterrell··on Tesla Live Stream – Autonomy Day [video]
I wonder if he's going to explain this position at all? Or if it's just posturing against Waymo et al. Seems like more data is always better than less data for this application?
robterrell··on Hollywood Upended as Unions Tell Writers to Fire Agents
Thanks, this was much more explanatory than the linked article.
robterrell··on Jepsen: YugaByte DB 1.1.9
Not a comment on YugeByte, but... I love it when a new Jepsen report get released. Kyle Kingsbury has single-handedly raised the bar on an entire industry. (Well, not single-handedly anymore, but still.)
robterrell··on Fixing the Internet for Games
Glenn, if you're still hanging around -- can the shader be written to account for the flow of P2P network traffic? Let's say I'm using an old-school configuration of a centralized lobby server that simply connects players to each other and the players connect directly over UDP?
robterrell··on Why the days seem shorter as we get older
Oliver Sacks wrote about time perception and aging as well:

robterrell··on Alex Gibney on the Fall of Theranos and Elizabeth Holmes
I believe the podcast "The Dropout" plays some of them.
robterrell··on Tesla Model Y
Got a mini-review for us?
robterrell··on The Planned Obsolescence of Old Coders
It seems pretty common with bigger companies: Google, Apple, Facebook, Amazon, Oracle, Box, Zynga, Electronic Arts, Pinterest, Microsoft, etc.

The tracks and levels are commonly referred to as the "job family architecture" -- don't be afraid to ask a recruiter for this information. Otherwise you'll never really know if you're being properly leveled. (For instance, I believe a Principal SE at Microsoft is roughly equal to a Staff Engineer at Google.)

robterrell··on The great 'Captain Marvel' soundtrack scam
I've noticed something similar on Apple Music -- if you search for "Russian Doll soundtrack" you'll find collections of songs made by what seem to a non-affiliated entity ("inSquamous"). At least, in this case, the songs are the real tracks in Apple Music, so the songs are getting properly monetized. I wonder if inSquamous is getting something off the top for curating the collection?

Same thing happened on Baby Driver's release day -- there was no official soundtrack for weeks, and some enterprising soul jumped into the breach with a collection of the songs.

robterrell··on The Planned Obsolescence of Old Coders
Many companies have separate tracks for independent contributors and managers. You can stay an IC and level up to Distinguished Engineer or Fellow or Staff Engineer or whatever, without needing to go into management.
robterrell··on This Is Silicon Valley
What city is this?
robterrell··on Why 80s BASIC still matters
Oh wow, I wrote games for Compute! magazine. Rather, ported them. Readers would submit games for their particular computer, an editor would select a few for each issue, and then we'd port them to the other popular 8-bit micros. Best high school job ever.

IIRC the guy who wrote the checksum generator also wrote the common assembly language graphics routines we used for all the games.

robterrell··on Linus Torvalds on Why ARM Won't Win the Server Space
There really are android phones running Intel atom CPUs. Can’t recall models off the top of my head but adding x86 support was a thing we had to do.
robterrell··on Build your own old-school 3D shooter in a weekend
It's a neat trick of projection, and really easy to hack on and extend yourself once you know the trick. Using your map of the space, cast a ray from the camera position through every column of the display rectangle; using the distance the ray travelled before intersecting the wall, you can calculate the apparent height of the wall seen in that column of the display; so, in that column, draw the wall that high. You can get fancier with textures for the walls, varying the floor height, walls that can appear and disappear (i.e. "doors"), and so on.

Better than my 10-second explanation: https://lodev.org/cgtutor/raycasting.html

robterrell··on Amazon Pulls Out of Planned New York City Campus
OMG don't give basketball players this idea. Cities would totally write tax exemptions into law to land LeBron!
robterrell··on Amazon, GM in talks to invest in electric pickup truck maker Rivian: sources
Both Toyota and Mercedes sought Tesla's help with EVs for their California "compliance" vehicles: both the RAV4 EV and the Mercedes B-class EV had a Tesla frame, motors, batteries, and drive controller underneath. I don't know about the MB but the Toyota was rumored to cost roughly 2x the list price. In 2014, after Toyota made roughly 2000 of them (the minimum required by law) they stopped.

You can read about the common problems on the forums; lots of the same problems Teslas had in the time period (i.e. loss of all propulsion while driving, loud motor noises followed by eventual motor failure, etc) in addition to software problems bridging the two companies' systems.

All solvable but I'm sure Tesla prefers selling $100k cars better than selling $15k generic skateboards.

robterrell··on California will not complete $77B high-speed rail project: governor
You are slamming the "Green New Deal Thinking" for not including EV semis and planes, vehicles no one yet builds or sells?

Semis are maybe more likely, but I don't want government energy policy to be planning on EV airplanes any more than, say, fusion reactors.

robterrell··on On Being a Principal Engineer
In our org it just means "not a manager." We have two tracks in engineering, IC and managers. You can stay on the IC track and continue to be promoted to positions of higher responsibility, without your comp getting dinged because you're not a manager.

It solves for the decades-old "well now what?" mid-career dilemma where an engineer would have decide if they wanted to keep doing what they love (i.e. coding) or go into management for the comp but leave the work they love behind.

I found it freeing. Not at all condescending.

robterrell··on On Being a Principal Engineer
Individual contributor. i.e. Not a manager.
robterrell··on Office Space turns 20: How the film changed the way we work
In the new modern version of Office Space, we'll take Jira into the field with a baseball bat...
robterrell··on Ask HN: What books changed the way you think about almost everything?
That book also gave us the term "meme" which, in its original form, is way more interesting than "animated GIFs spread on social media."
robterrell··on Facebook Loses Fact-Checking Group Snopes After Two Years
I spent a stupid number of hours fighting disinformation on FB during the 2016 election -- responding to batshit crazy links from FB friends who were getting fed their batshit crazy from what we now know were 100% trolling-for-bucks fake news sites, or straight-up foreign disinformation efforts.

I don't have a catchy derogative name for a future where truth is determined by the number of upvotes, but it's clearly not less dangerous than an "Orwellian" future where truth is established by elites.

Also -- Snopes is hardly Big Brother.

robterrell··on Locast, a Free App Streaming Network TV, Would Love to Get Sued
I just explained this to my son yesterday, ending with a demo where I dug up an old coax antenna, connected it to the TV, and showed him channels of free content (also, what static looks like). He was amazed. (What else have I forgotten to tell him about? I've failed him as a father!)

He thought the over-the-air picture quality was better, which considering the bitrates he's used to with Netflix and YouTube, is probably true.
