alberth··on WSL 2 is getting faster Windows file system access
Would you mind elaborating (for those of us uninformed)
alberth··on MacBook Neo is so popular that Apple doubled production
I wonder what the margin profile is of the Neo vs Air vs MacBook Pro.

I have to imagine the Neo is lower margin %, but maybe I'm wrong.

alberth··on Squillions: How money laundering won
That super expensive thing could be an NFT you created & sold.
alberth··on Squillions: How money laundering won
> I haven’t even mentioned gold, which is used all the time in criminal transactions, let alone cryptocurrency, the single biggest recent innovation in money laundering.

Curious how that line is received within the HN crowd.

alberth··on Talking to strangers at the gym
This reminds me of a college dorm friend who always seemed to be on a date with someone new.

His philosophy was simple: “It’s the law of large numbers. If you ask enough people out, and don’t fear rejection, you’re eventually going to get a yes. And along the way, you build the confidence and skill to ask better.”

alberth··on GitHub's Historic Uptime
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.

alberth··on Launching Cloudflare's Gen 13 servers
Dupe of later post: https://news.ycombinator.com/item?id=47495795

alberth··on Apple discontinues the Mac Pro
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.

alberth··on Cloudflare's Gen 13 servers: trading cache for cores for 2x performance
It seems like the unspoken takeaway is just how shockingly performant LuaJIT is, even relative to Rust.
alberth··on 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.

alberth··on I wanted to build vertical SaaS for pest control, so I took a technician job
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?

alberth··on Epoch confirms GPT5.4 Pro solved a frontier math open problem
For those, like me, who find the prompt itself of interest …

> A full transcript of the original conversation with GPT-5.4 Pro can be found here [0] and GPT-5.4 Pro’s write-up from the end of that transcript can be found here [1].

alberth··on Migrating the American express payment network, twice
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.

alberth··on Migrating the American express payment network, twice
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?

alberth··on Elon Musk pushes out more xAI founders as AI coding effort falters
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.

alberth··on Claude March 2026 usage promotion
Anthropic, can I please signup without the need to share my mobile number.
alberth··on The Isolation Trap: Erlang
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.

alberth··on Meta acquires Moltbook
I didn't realize Moltbook and OpenClaw - were created by different people.
alberth··on Kuwaiti F/A-18's Triple Friendly Fire Shootdown Gets Stranger by the Day
> This is the latest video to have emerged from the extraordinary incident earlier this week in which a Kuwaiti Air Force F/A-18 Hornet was responsible for shooting down three U.S. Air Force F-15E Strike Eagles.

Why is the US using such dated planes?

alberth··on Cloud VM benchmarks 2026
They have the higher cache variant (4585PX - same clock speed & core count)

https://us.ovhcloud.com/bare-metal/advance/adv-4-new-gen/

alberth··on Cloud VM benchmarks 2026
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.

alberth··on Found: Medieval Cargo Ship – Largest Vessel of Its Kind Ever
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.

alberth··on What a year of solar and batteries saved us in 2025
Wont you need to replace the batteries around Year 10 and then this becomes a wash?
alberth··on Show HN: Terminal UI for AWS
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)?
alberth··on When square pixels aren't square
Am I missing the obvious, but it seems like the author is messing with the aspect ratio.
alberth··on Why outcome-billing makes sense for AI Agents
So who's the arbiter to determine if the outcome was achieved?

And how do you programmatically measure it?

alberth··on No Graphics API
Would this be analogous to NVMe?

Meaning ... SSDs initially reused IDE/SATA interfaces, which had inherent bottlenecks because those standards were designed for spinning disks.

To fully realize SSD performance, a new transport had to be built from the ground up, one that eliminated those legacy assumptions, constraints and complexities.

alberth··on Mozilla appoints new CEO Anthony Enzor-Demeo
Dumb question: who’s Firefox target user?

Chrome is able to capture the mass consumer market, due to Google’s dark pattern to nag you to install Chrome anytime you’re on a Google property.

Edge target enterprise Fortune 500 user, who is required to use Microsoft/Office 365 at work (and its deep security permission ties to SharePoint).

Safari has Mac/iOS audience via being the default on those platform (and deep platform integration).

Brave (based on Chromium), and LibreWolf (based on Firefox) has even carved out those user who value privacy.

---

What’s Firefox target user?

Long ago, Firefox was the better IE, and it had great plugins for web developers. But that was before Chrome existed and Google capturing the mass market. And the developers needed to follow its users.

So what target user is left for a Firefox?

Note: not trolling. I loved Firefox. I just don’t genuine understand who it’s for anymore.

alberth··on Google releases its new Google Sans Flex font as open source
If you like variable fonts, no font is better at giving fine tune control than Roboto Flex (also by Google).

Has 12-axis of variables (whereas most only have 1 or 2)

alberth··on A supersonic engine core makes the perfect power turbine
> Power generation turbines are designed to work at ambient sea level conditions. They don't rely on ambient air being especially cold for cooling, they can keep cool thanks to the large mass flow rate

What could be contributing to this is recently Vertasium did a whole video on how jet engines operate at temperatures above their components melting point.

And how the cold air at altitude is what keeps it from melting.
