Unsolicited feedback ... changing the y-axis to be hours (not % uptime) might be more intuitive for folks to understand.

The data is there, you just have to hover over each data point.

New comment by alberth in "Apple discontinues the Mac Pro"

alberth — Fri, 27 Mar 2026 14:42:37 +0000

Just a reminder that the old Intel Mac Pro could handle 1.5TB of RAM ... today's Mac Studio can only handle 0.25TB.

Seem odd that a computer from a decade ago could have more than a 1TB of incremental RAM vs what we can buy today from Apple.

It seems like the unspoken takeaway is just how shockingly performant LuaJIT is, even relative to Rust.

New comment by alberth in "Flighty Airports"

Flighty is very pretty, but I’m not giving up FlightAware anytime soon.

I travel a lot, and frequently encounter flight delays. It’s mind boggling difficult to find out where my plane is when it’s delayed via Flighty. This and a few other things, FlightAware gets right.

I feel like Flighty is for rare leisure traveler and FlightAware is for weekly business and/or pilot traveler.

I’ve honestly had better luck with iOS built in flight tracker than Flighty itself.

I’m genuinely inspired by your journey.

One question for clarity: why don’t you see an opportunity to sell AI or other technology into this space again? Is it just because incumbents already have it locked up and it’s cheap?

The reason I ask is that this feels like one of those moments in history similar to mobile. PlanGrid succeeded because tradespeople suddenly had iPhones and iPads in the field, which made it possible to digitize blueprints and collaborate in real time.

Put differently, what could be the new “PlanGrid” for your industry - that AI makes possible now, the way mobile once did for construction?

New comment by alberth in "Migrating the American express payment network, twice"

alberth — Mon, 23 Mar 2026 04:05:51 +0000

I’m fairly certain that’s a POS issue, not the payment network.

I’ve heard anecdotally that it’s < 140 ms for payment networks.

Anyone, please correct me if you know better.

Re: transition to micro services (from monolith).

I’m surprised a network so sensitive to latency (as are payment networks), was able to achieve their latency SLAs with micro services.

Maybe Amex being a closed-loop network helps with latency?

Let’s restate this another way:

“ In an interview with {COMPANY} I was literally told that … {COMPANY-OWNER} can call us and demand anything at anytime. “

Doesn’t sound so crazy when Elon name is removed from it.

Note: I’m no Elon fan, but do think sometimes HN overreacts when his name is mentioned.

Tangentially related: I haven’t seen DragonflyBSD talked about on HN in a long while but wasn’t it a split from FreeBSD to be built entirely around message passing as the core construct.

And with the tiny team working on it, it has remarkable performance.

I didn't realize Moltbook and OpenClaw - were created by different people.

Why is the US using such dated planes?

They have the higher cache variant (4585PX - same clock speed & core count)

Both Datapacket & OVH have the 4565p.

This proc is a hidden gem.

For most workloads it’s not just the most performant, but also the best bang-for-buck.

Who would have guessed the Smithsonian of all organizations would have so many video popup ads.

Isn’t the greatest experience on mobile when so little of the content can be seen due to popups.

Embarrassingly dumb question: if you’re one of the few users who don’t run a dark background terminal … how well do these TUI render (in a light background)?
