maxcan··on Bob Lee, former CTO of Square, has died after being stabbed in San Francisco
Exactly. I suspect (without much evidence) that most murders in Miami are gang related, so even less likely to affect HN readers whereas in SF it feels more random.

SF's homicide rate is low, lower in fact than Miami.

But, its non-violent crime and property crime numbers are through the roof which makes it feel incredibly unsafe.

Miami, on the other hand, actually has a higher homicide rate than SF but because the streets are clean and property crime is much much lower it feels far safer than SF. Also, to be honest, for people reading hacker news, homicides are an incredibly rare black swan event, unlike property crime which you experience almost daily in SF. So, it makes sense for this crowd to have a place higher utility on low property crime than on low homicides. And I'm not judging, I moved to Miami and couldn't be happier with that decision.

maxcan··on Who Blew Up Nord Stream? Investigators Focus on Mysterious Passengers on a Yacht
Exactly. If you imagine Russia as a unitary rational actor, it makes no sense to blow up the pipeline since they would have had the optionality to shut it down anytime they wanted without destroying it.

However, as part of an internal power structure, it does start to make sense. For example, you could see someone like Prigozhin (sp?) as potentially having a lot to gain from the attack. It would weaken his rivals with ties to the gas industry, and by "shooting the hostage" make Germany more likely to support Ukraine, leading to a longer, more drawn out war which benefits Wagner in all sorts of ways.

maxcan··on Bill Ackman: The gov't has about 48h to fix a-soon-to-be-irreversible mistake
I believe (and I could be wrong) that this was scheduled in January and by that point rates had already gone up quite a bit. It is pretty safe to assume that any executive at SVB knew the writing was on the wall at that point.
maxcan··on Tesla was likely on autopilot in deadly fire truck crash in Bay Area, feds say
You are absolutely right. When I look at the ridiculous numbers of preventable vehicle deaths in our country, caused almost entirely by carelessness, I do wish that getting a driver's license was much much harder and that we actually bothered to enforce traffic laws consistently.
maxcan··on Tesla was likely on autopilot in deadly fire truck crash in Bay Area, feds say
Ok, and how many drivers have crashed into emergency vehicles when being driven by humans? Without that number, at a minimum, the article conveys very little meaningful information.

Also, anyone who has ever used an actual aircraft autopilot knows that they are actually very similar to what Tesla has. They relieve you of making constant control inputs need near constant supervision. Is the marketing deceptive, perhaps, but its not incorrect.

maxcan··on Gang members hold positions at ‘highest levels’ of LA Sheriff’s department
For me, 'regulators' sounds like a bunch of guys who regulate any stealing of his property. They're damn good too. Can't be any geek off the streets.

I suspect this is a different group.

maxcan··on CoffeeScript for TypeScript
Maybe its being a former haskeller, but the engineer in me absolutely loves this.

The CTO in me is horrified at the idea of writing a whole bunch of civet code for it to die a coffeescript style slow death. If it catches on I'll be all over it though.

maxcan··on Dishonor Code: What Happens When Cheating Becomes the Norm?
So basically the only solution is for colleges to actually care about undergrads and run undergraduate classes just like graduate seminars where the students have to interact, in small groups, with the faculty for faculty to gauge their command of the subject matter.
maxcan··on Ask HN: What would be your stack if you are building an MVP today?
Besides Hasura, every element of the stack is either the dominant tool in the market or one of the most dominant tools in the market (terraform). Hasura is pretty thin and not too hard to pick up.

Please enlighten me as to which “batteries included frameworks” have the market dominance of AWS, React, TypeScript, and Terraform?

maxcan··on Ask HN: What would be your stack if you are building an MVP today?
Data: Postgres & Hasura (for me Hasura is the goldilocks level of abstraction - lets me skip writing CRUD handlers, but doesn't get in the way either when I need to do something complex).

Frontend: TypeScript, React, apollo client, graphql-code-generator, tailwind

Backend Logic: Lambda functions written in TS, packaged with serverless.com, but deployed with Terraform

CI: GH Actions

Deployment: AWS via Terraform. One account per environment under an umbrella org.

Because I've used this stack so many times I can get a "shovel ready" foundation going in minutes with a skeleton that I've been iterating on.

maxcan··on Ain't it funny how the knight moves?
This is the way.
maxcan··on Show HN: Quick tunnels to localhost with one command and no binary download
Very cool. I switched to cloudflare tunnels from ngrok a while back after having some issues with ngrok.

However, CF Tunnels were far from ergonomic or easy to use ( https://www.maxcantor.com/blog/2021-10-15-ngrok-to-cloudflar... ).

I'd love a simple tool that fills the gap and I think this is it.

maxcan··on FAA NOTAM System Outage
Double nit: this was not a misuse the deprecated term "The Ukraine" but the correct use of 'the' attaching to "Ukrainian one" referring to the NOTAM basically telling everyone to remain clear of Ukrainian airspace.
maxcan··on FAA NOTAM System Outage
100%. As a GA pilot who mostly flies under IFR, the NOTAM system is borderline useless to me.

For every warning about an approach being altered or a runway closed, there are 100s of "birds invof airport" or "unlit crane 50' AGL 5 miles from the field" NOTAMs. And even for the relevant NOTAMs, Foreflight will highlight them for approaches etc and ATC won't send you to a closed runway or taxiway.

maxcan··on Tesla FSD data is getting worse, according to beta tester self-reports
Highways are a dream, works fine.

For the most part it works fine in Brickell and downtown. I put a link to a street view of one tricky intersection above. It also struggles here when you're trying to go south on Miami Ave:https://www.google.com/maps/@25.7626232,-80.1929899,3a,75y,2... basically where the black car is going south it needs to follow the street in a 90deg curve to the right then immediate left at the stop sign. Sometimes it tries to just go straight there, i.e. to where the truck is.

Also, i do often need to "intervene" by pressing the accelerator since the car is a bit to passive for the typical lunatic miami drivers.

maxcan··on Tesla FSD data is getting worse, according to beta tester self-reports
This is relatively consistent with my experience using the FSD Beta in and around Miami with one major caveat.

With two exceptions, all of my disengagements have been "quality of life" disengagements where I disengaged for reasons other than safety:

* to take a different route or get in the correct lane * to be polite / courteous to a pedestrian who wasn't yet in the crosswalk * to move more quickly through a construction zone or other traffic irregularity.

In none of those cases did I believe that the car was going to cause any risk of an accident, at best there was risk of pissing someone off (which, to be fair, in a city like Miami with far more firearms than judgement could be fatal, but not due to car at all). So yes, these are disengagements, but they weren't dangerous.

There is one case where I do get dangerous disengagements. At the intersection pictured below, when I'm in the position of the white van, sometimes tesla will mistake a green on the far traffic light (which is for the other road, intersecting at a sharp angle) for my road and proceed if it is green even though it is red. Happened twice, haven't noticed on the last version yet. Intersection here: https://www.google.com/maps/@25.750348,-80.2061284,3a,75y,26...

maxcan··on Cleared to Collide: The crash of USAir flight 1493 and SkyWest flight 5569
Admiral Cloudberg's medium posts are always incredible, but this one really struck a cord and made me contemplate how amazing some of the institutions in the US Government truly are.

It's all too easy to look at the SEC's absentee mishandling of crypto or whatever and take a dim view of US institutions. But all the way back in 1991, the NTSB was able to look at this accident, with a glaring first order cause of human error on the part of the controller, and recognize that it was actually a systems problem wherein any controller could have made the same mistake. Having agencies take actions like this, instead of a more typical CYA throw-the-individual-under-the-bus approach is something we should all appreciate.

maxcan··on Electric scooter ban increased congestion by 10% in Atlanta
a few of the providers required a photo of the scooter when you ended your ride. seems to address that issue.
maxcan··on Electric scooter ban increased congestion by 10% in Atlanta
Its like cities had zero controls on parking then just banned cars instead of building effective parking enforcement laws.

Simple solution:

1) Cities establish guidelines on legal parking / riding. 2) Impose large fines for violations. 3) Scooter companies pass on those fines to the rider who parked illegally.

But instead we have a bunch of blue cities banning the most affordable, equity enhancing, zero emissions, last mile transportation solution.

maxcan··on Air Force Plans New Blended Wing Body Cargo/Tanker Aircraft by 2027
I wonder if the design of blended wing body aircraft means that airlines will be more weight constrained by volume constrained. If that is the case, it would be economical for them to have much wider aisles (faster boarding) and exit rows which could offset the negative impact that having more than 2 aisles would have on evacuation time.

I believe that is somewhat offset by having larger rotational inertia as more mass is further from the center. That does however, necessitate larger control surfaces achieve the same roll performance.\

Also, anecdotally from my flying (I'm a private pilot, small, single engine planes) turbulence tends to create much more vertical translation and pitching movement than it does roll movement.

maxcan··on The enduring mystery of ‘Jawn,’ Philadelphia’s all-purpose noun (2016)
Philadelphia born and raised and for my life I couldn't define what 'jawn' means.
maxcan··on GitHub Outage
Github outages are the bored engineer's equivalent of getting a surprise snow day when you were in school, full of unbridled joy.

For engaged, happy engineers its the equivalent of getting a surprise snow day when you are grown up and have to go dig your car out of the snow and its a normal day just with extra steps.

maxcan··on What would make AWS even better
Long running lambda functions are called AWS Batch. It’s a relatively unknown service but pretty decent if you need something like a GPU or long running jobs and can tolerate a 90 second cold start.

Since terrestrial LTE/5G can penetrate aluminum aircraft hulls, does this mean cell service in the air?
maxcan··on Ask HN: What HN post made you money?
Long term (10-30 years) buy and hold in publicly listed companies who had something about them which I did not believe could be accurately reflected in financial statements. Mostly AAPL and TSLA.
