-warren··on I rewrote PostHog's SQL parser, 70x faster, while barely looking at the code
I think thats exactly what indirectly happened. This guy didnt optimize the parser. Someone else did -- years ago. That work was pulled into the LLM and made it look like magic.

Thank you for that!

There used to be (before preorder) an option for an extended battery. Am I missing it hidden in the customizer?
-warren··on Boot Naked Linux
> cpio is a very weird and ancient program with a command line which makes tar look user-friendly. But let’s not worry about the details for now.

So true. Been using cpio sporadically for many (many) years. And I still have to look it up. But at least I don't have to do `info cpio` anymore.

-warren··on Nobody ever gets credit for fixing problems that never happened (2001) [pdf]
My time in IT has really oscillated between these two extremes:

- "Everything around is working just fine. What are we paying IT for?"

- "Everything is broken. What are we even paying IT for?"

Personally, I strive for the former rather than the latter; I like to say "If I do my job right, you never know I'm here." But that's what got me let go.

(and for karma's sake, I keep in touch with folks at the old company; it's an absolute crapshow. So I got that going for me; which is nice)

-warren··on What Is a Dickover?
Dickovers are annoying -- tell me, what's your solution? For me, a combination of a) not patronizing these sites, but when I have to b) some ad blockers help. Nothing seems to work well though.
-warren··on Hindenburg’s Smoking Room
Ok now thats wild!
-warren··on Hindenburg’s Smoking Room
Story time. Last summer I flew from ATL to SFO on a brand new Airbus. Pretty cool plane! Halfway across the count I had the obligatory restroom break. In the head, I noticed an ashtray. I was confused -- "smoking has been banned in planes doe decades. Why is there an ashtray here?"

I flagged down a flight attendant and asked them. Their answer was that yes smoking is banned, and it's a $250 fine. But EVERY SINGLE TRIP from ATL to SFO, someone decided it is worth it and the ash trays give them a safe place to put it out. The flight attendants wait outside the lav after the smoke alarm goes off with the ticket.

-warren··on GitLab announces workforce reduction and end of their CREDIT values
I hear you my friend.

We've all heard the joke about two people running from a bear and only one has to be less eaten than the other.

This is a race to the bottom. We shall see who winds.

-warren··on Nintendo announces price increases for Nintendo Switch 2
I know it's stupid and phschological, but there's a line in my head on what the absolute maximum I'd pay for the nsw2 once the right game comes out. That line is $450.

At $500, I will think twice about just buying nsw1 games, moving to thr steam deck, or digging out old consoles (which is fun too!)

I'm really having a hard time (stupid, I know) giving my kid a $500 toy. Somehow I'm ok with a $300 toy (nsw1) or even a $400 toy (old smartphone).

-warren··on Sierra Raises $950M at $15B Valuation
Somehow, I think we're missing the point and maybe braincells are being sent in the wrong direction. Well designed products don't need good customer support. My toaster works well. Haven't called them once.

If we are designing a thing is so terrible that it makes customer support necessary (other than the obvious corner cases that ai cannot solve) then sure, let a computer do it. We’ve already failed at every other step.

-warren··on Meta tells staff it will cut 10% of jobs
While I cannot respond as a doctor, I can respond as an EMT. Totally different. But heres the deal.

The person who is the most important to you on the worst day of your life is the emt. The interview was literally "do you have a drivers license, and are you grossed out by stuff?" The rest you learned on the job.

Weird how doctors are vetted but prehospital folk are not.

edit yes there is training, but it happens after hire

-warren··on Meta tells staff it will cut 10% of jobs
So let me ask this. What is the perfect mix of inerviews and durations?

If you ask my blue collar friends, the answer is one and however long it takes to drink three beers.

If you ask any married person, the onboarding process (courtship) may last YEARS and consist of many interviews (dates).

As an EM, ive always struggled with this one. Im about to invest some serious coin and brainspace for you, so I tended towards a max of 3-6 total hours and a takehome assignment.

As an IC, I preferred short and sweet. Heres my portfolio (github), heres my resume. Lets make this work. Maybe 1-2 hours; its not like we're getting married.

The happy place has to be in there somewhere. Whats your take?

-warren··on You don't need advice from editors on rejected manuscripts
This is a great blog post and very sound advice.

I, however, miss twitter's "twitterness". 140 characters and a link.

-warren··on Alberta startup sells no-tech tractors for half price
I disagree. While those are great points, I don't think that's the primary reason -- and maybe we're actually saying the same thing.

This tractor will last 50 years (and maybe more). Your grandchildren will be able to still use it. That longevity is the primary reason farmers would be super interested in this.

Some jobs (like mucking a barn for example) don't require a high-tech tractor. Sometimes you just need a workhorse that you can trust will start, run and do the job. Every single time. I still see farmers running old minneapolis-moline tractors from 100 years ago!

-warren··on EFF is leaving X
Oh. That X (not x11). Makes sense
-warren··on How to make a sliding, self-locking, and predator-proof chicken coop door (2020)
My chickens must have been born in the Bronx, because they've cornered an opossum, bloodied coons and only one has ever "lost" to a fox.
-warren··on Newly purchased Vizio TVs now require Walmart accounts to use smart features
I think Robinhood bought x1, so I think the Robinhood gold card is the same thing (citation needed). I pay something like $100/yr and the app generated numbers on demand.

I made the choice that my privacy was worth something so I pay for proton , my x1 and burner.

-warren··on Newly purchased Vizio TVs now require Walmart accounts to use smart features
Valid points! I do create a separate email (proton has an alias generator and allows unlimited if you pay), credit card, and phone number for each service. Adds about 90 seconds to each sign up, which is a great chance to ask myself if I really need that service .

X1 (and I bet there are others) have a button called "free trial" cc that generated a real, valid anonymous (j doe) cc that cannot be used for an actual charge. When I pay for things (I do), I creat a separate virtual card for each service. Side benefit is when I want to cancel, I don't have to find the dark-pattern account cancel button. I cancel the cc and the email. No more subscription; no nagging.

-warren··on Treason in the Futures Markets
Agreed. War Profiteering [0] is probably a better term.

[0] https://en.wikipedia.org/wiki/War_profiteering

-warren··on Newly purchased Vizio TVs now require Walmart accounts to use smart features
This is why I have protonmail aliases, a burner second phone, and an x1 virtual cc. While I can't stop the enshittification, I can fight back by remaining pseudo anonymous and compartmentalize each service.
-warren··on I was interviewed by an AI bot for a job
I've done several of these. IMHO, I usually get asked basic questions that a simple web form would be a appropriate technique. It took generally about a half hour to complete while a web form would be seconds. I think it's the wrong tool for the job.
-warren··on Show HN: TopicRadar – Track trending topics across HN, GitHub, ArXiv, and more
25 trackers blocked. Certainly there's a better way
-warren··on The recurring dream of replacing developers
I think you're onto something. Replace "developers" with "doctors" I that statement and you've described healthcare in the mid 1900s. Replace with "masons" and we describe the medieval times. There is always a specialized class
-warren··on Efficient method to capture carbon dioxide from the atmosphere
Sounds like this would be great on a long haul space mission where carbon capture is small scale, but very important!
-warren··on DOOM could have had PC Speaker Music
I'm going to date myself here. In 199x, we had a 286 and loved a game called "Command HQ" that had lovely gameplay and sound to boot! Then we got the ol' Packard bell 486 with a sound blaster. We played the same game (which had midi output too) for the first time and my father and I cried -- it was unbelievable.

That's when I first became enamoured with the "art of the possible" and this has driven my career.

I fully believe that doom could have had pc speaker sound; after all w3d did!

-warren··on Testing shows automotive glassbreakers can't break modern automotive glass
In fire school we learned PASS -- pin, aim, squeeze, sweep. Even well-trained professionals need simple mnemonic devices.

Also, we never used a seatbelt ripper -- they don't work. All first responders carrier trauma shears. Those do work and have multiple purposes.

Résumé/CV: https://warrenandrachel.com/warren/assets/resume-2024.pdf

Email: warren at warrenandrachel.com

Background: 25 years of tech. If there's a job done in or around IT, I've done it and done it well. I started with dumb terminal migrations and build world-class databases today. As I like to say, I know the whole data stack from "Silicon to SQL". Lately, I've specialized in building amazing engineers. If you need an amazing team of engineers (think NASA or SpaceX) over a team of amazing engineers (think Justice League or Avengers), then I am the leader you need!

-warren··on Synthetic gasoline
Dumb question, and I might not understand the difference. Don't we already have synthetic gasoline in the form of trufuel and the ilk? I can buy that at walmart; expensive, sure, but is indoor-safe and lasts forever. Smells good when it burns as a bonus!
