ectoloph··on Claude Says
We live in an interesting time.

I have been in meetings where the conversation has been 'my Claude has got feedback', 'great, I'll get my Claude to take a look'.

When do you just cut out the human middleware in that process?

ectoloph··on Show HN: JBR-001 – An open-source 3D printable desktop robot
I'm not sure any of the other Arduino platforms would be able to do the computer vision parts this appears to.
ectoloph··on Everyone has ADHD because we made it up
I wasn't sure how I felt about this article but I think the author sums it up really nicely.

> What actually separates “I lost my keys” from “I have ADHD” was never the presence of the behaviour. It’s the degree of impairment — how much it’s costing you, how often, for how long, etc.

ADHD can be a real dichotomy. On the one hand, yes you can be successful and holding down a good job. But you may be doing so by existing on the edge of burnout and questioning when everyone else figures out you are faking the competence they see in you.

But people often don't see the frustration, despair or how much work finding systems to work with or around your brain has gone into it too.

Sometimes, the most helpful part of diagnosis is that you can name the experience. Otherwise you end up concluding you're worse than everyone else.

ectoloph··on Inside ZCode: Silently uploading your Git history to the cloud
Is it naive to assume that the agent will try and access anything on your disk, either accidentally or maliciously?

Permissions classifiers in auto mode are just models trying to guess if they're doing the right thing.

Claude Code will tell you that it went around a sandbox because the sandbox blocked it. At which point, you ask yourself the point of the sandbox.

ectoloph··on I don't like passkeys
I am conflicted with passkeys.

I actually prefer non-resident U2F in some ways. You don't have to store anything on your key, you are just signing requests. This is relevant where U2F/FIDO keys have limited slots for 'resident' keys.

In principle, it's great. You have one good password to remember for the average user, and that's enforced by their device's probably good enough security posture.

They are resistant to being phished and they won't reuse the same one everywhere. They then don't end up going from hunter2 to hunter2! everywhere.

But my experience for users is that they worry they are giving their biometrics to Amazon or whoever and so the UX just confuses them.

The certification aspect was new to me too last time passkeys came up. Sites can require that a given passkey has been certified.

The patchy support for them is also frustrating. MacOS does not support NFC FIDO/U2F. iOS does.

ectoloph··on Ask HN: How to recover Google auth after phone stolen?
I always feel conflicted with this.

Using my password manager to store 2FA codes is convenient, but it adds a layer of indirection if they are elsewhere.

But if you've compromised my password manager, you almost certainly have enough access to my machines to get to the alternatives.

ectoloph··on The Return of Sail Power: Cargo Ships Are Turning Back to the Wind
Stena claim that their Flettner rotors (spinny sails) reduce fuel use by 9%.

https://stenaline.com/media/stories/introducing-stena-connec...

They are in commercial service already on the Irish Sea.

ectoloph··on Carmakers Have a New Idea to Boost EV Range: Add a Gas Engine
The REX issue is an interesting one.

The BMW i3 used what was basically a scooter engine. The Ampera/Volt used what was essentially an Opel Corsa engine (from memory).

Toyota's approach of using a small battery and modified atkinson cycle engine seems to have paid off. Taxi drivers love them and fuel economy is pretty consistent. But the engine is a core part of the process. So it isn't dead weight a lot of the time.

The real question is whether an 'Extended Range EV' is using a motor intended to work efficiently as just a generator or whether it's another parts bin special.

ectoloph··on Ask HN: Are others seeing Google's reCAPTCHA rejecting Firefox users?
I've found that I can often stuck in tarpits on Safari for iOS with Wipr and iCloud Private Relay.

The worst trigger is searching Google from the address bar.

Loading the homepage first makes the problem notably less common. Or getting a couple wrong.

ectoloph··on Why getting your hands dirty is good for you
Kids benefit from being kids and rolling around in the grass.

In which cities are people favouring local parks over toilets?

Parasites can actually help with allergies. I am loosely aware of various attempts at treating allergies using parasites.

One of the approaches taken (under medical supervision) for kids with bad nut allergies is to gradually expose them to more of the allergen. Being able to survive a peanut or two without anaphylaxis is life-changing.

ectoloph··on Decapitating a MacBook (2025)
The idle cost of inverters can be quite high.

EcoFlow power stations draw somewhere around 30w with the inverter switched on with no load.

The idle power of a Mac Mini at the wall is a few watts total.

ectoloph··on Steam Deck / SteamOS hit over 30k Verified and Playable games
It's worth mentioning that the difference between playable and verified is sometimes just control mapping, or the wrong icons being shown, or default graphics settings need to be adjusted.

Games often run well when they aren't flagged as verified or playable too. The remapping UX via Steam/Steam OS is good enough that I've happily played a lot of keyboard and mouse-only games well too.

ectoloph··on Tim Curry has died
This is sad news, he was a very good actor.

One of my favourite roles I've seen him in was as Trymon in the TV version of Terry Pratchett's The Colour of Magic.

ectoloph··on Nobel Disease
In the article, Milton Friedman sums it up well I think by describing the attention is 'corrupting'.

It cannot be good for you for everyone to assume that you are somehow omniscient all of a sudden.

At either extreme, it isn't good. You start believing it and overestimating yourself more and ore, or you are buried under an ever increasing sense of impostor syndrome.

ectoloph··on Don't be a meat proxy
Friends don't make friends read slop.

If I have something Claude wrote then I will offer the LLM output. But I generally prefer to at least give the option.

I have seen conversations where it has boiled down to an exchange of A's Claude responding to B's Claude with a retort and fixes from A's.

ectoloph··on The AI Productivity Gap
AI is a force multiplier.

It multiplies both good and bad decisions. Both mine and it's 'own'.

I can get some things done 10x faster and it might even catch mistakes or help me solve something difficult.

But if I am being lazy or complacent then it bites me that much harder.

ectoloph··on Claude Is Down
Sorry folks, my fault.

I finally went from Pro to Max after hitting another 5 hour session limit today.

ectoloph··on ReFrame – The EPaper Camera
I really enjoyed playing with dithering to get good results from the eink spectra displays with 6 or 7 colours.

They end up making good photo frames, especially for older digital photos.

ectoloph··on Elevated errors on Claude Opus 5
These bursts of downtime are one of the reasons I end up with multiple smaller subscriptions between providers.

I'd just end up being really annoyed about the downtime if it lands in the middle of a working day.

ectoloph··on Ask HN: Why don't we solve aging?
Is death in old age a 'problem' to solve?

Suffering, absolutely. But I think there is more nuance to death.

ectoloph··on How My Images Are Dithered
Didder[0] is a good tool for dithering. I use it to pre-process images for the 6-color e-ink displays.

You can go down a rabbit hole of dithering algorithms too, like Floyd Steinberg[1]

ectoloph··on Passkeys were invented by engineers with zero understanding of consumer brain
Passkeys are a mitigation against users being bad at password hygiene and phishing being a real issue to users.

You can't phish a passkey, and you don't rely on the user providing you 'hunter2' on every site.

As for vendor lock in? No. The specs are open. You can run the code on a microcontroller, or, you can keep it in your arm with something like the Vivokey Apex. Note that the FIDO2 for the Apex is an open source Javacard applet.

The UX on the other hand is not great. If you have a password manager, your OS may prompt you which target to store the passkey with.

ectoloph··on Show HN: I replaced a $120k bowling center system with $1,600 in ESP32s
I think that an overview of how the machinery works and how it interfaces would be interesting.

As a side note, I do enjoy the bizarre bowling animations that the screens come up with.

ectoloph··on Count Binface
Net Zero isn't what sets the price of UK electricity generation.

Marginal pricing means that gas sets the price.

At time of writing, gas is only generating 6.9% of the UK's electricity. https://grid.iamkate.com/

ectoloph··on Why were Covid vaccine trials so fast?
Unfortunately, any viral infection can leave lasting damage too.

One of the outcomes of COVID was more awareness of post-viral syndromes.

ectoloph··on Show HN: MiniPCs.zip – Charting the Pareto frontier of Mini PCs
I like the little Mini PCs.

I have a GMKtec nucbox with an Intel N100 and an M5 Plus.

The biggest issues with them are around firmware and power consumption, especially idle. It's hard to get them as low as some of the bigger vendor devices.

The M5 plus sometimes resets its fTPM and won't boot without user input until that is resolved.

I can get the nucbox to idle around 4-5w and the M5 plus idles closer to 8w.

Most of the BIOS options are hidden or obscured for power saving.

The worst offender though is Beelink which idles at closer to 30w in the GTi14.

ectoloph··on Fossil Fuels Are 40% of Freight Shipping Tonnage, but Half Its Fuel Use
As I understand it, it's a mix of factors.

Charging Lithium, and converting to motive force in motors are both pretty efficient. (Both >90%).

An ICE vehicle has an upper limit on efficiency that is lower than what a modern fossil fuel plant can reach, and the ICE is less likely to sit at peak efficiency all the time. The world record, set this year was 48%. Previously, it was 41%.

Power plants are much more likely to be kept at or near their peak efficiency and have the space for systems like heat recovery (to recapture waste heat) and emissions controls. For a gas turbine plant, I think the record is ~64% sustained.

ectoloph··on Commodore Releases Flip Phone
I really like the concept, but I think the restrictions are a double-edged sword.

The form factor and Sailfish are a lot more appealing than 'apps blocked at a system level'.

Can it run the usual apps like banking apps which can be particular about Android 'trustworthiness'?

Unfortunately, a smartphone is a near-necessity for various things like that now.

ectoloph··on Show HN: Trace – Offline Mac meeting transcripts you can flag mid-call
I've just bought it based on the description.

Minor complaint is that it steals Cmd-Shift-P (Firefox Private Browsing shortcut) by default.

Easy to change in the UI though, so no big deal.

ectoloph··on I tested every IP KVM in my Homelab
I have a mild distrust of some of the cheap IP KVMs. I don't think vendors are malicious, but I don't expect they get it right every time either.

Admittedly, I haven't looked at any open-sourced firmwares either which could have improved things.

I have found the Sispeed USB KVM very useful, the convenience is well worth the $50 it cost me. The UX isn't great but you don't really need it to be. It works (most of the time) via WebUSB for the keyboard mouse.
