heeton··on Phoenix.new – Remote AI Runtime for Phoenix
Yea CC is great with phoenix / liveview. It’s been doing things that teach me new tricks about elixir I didn’t know yet.
heeton··on Timescale Is Now TigerData
Bad choice imo, given that there is another database called tiger beetle. I assumed they’d merged when I saw the title.
heeton··on Why I wrote the BEAM book
I understand it’s poorly promoted by the biggest users. But more of the web and world infrastructure runs on it than you realise.

Here’s an old post with some examples - https://www.erlang-solutions.com/blog/which-companies-are-us...

heeton··on Exeter's unassuming co-op worker leads double life as 'Lord of the Logos'
I wouldn’t call it a scene, but there’s a small handful of people and the occasional meet-up or event. I’m near Exeter after working in London for ~10 years.

Hi to anyone else who’s down in Devon :)

(Hit me up via my profile if you’d like to grab a coffee)

heeton··on Bare: Run JavaScript Everywhere
I still can’t tell if this is an April Fool’s joke or not.
heeton··on Utah becomes first US state to ban fluoride in its water
You need zero water to brush your teeth with toothpaste. Many dentists even say it’s preferable to not rinse your brush before and not rinse your mouth after.
heeton··on Trees not profits: we're giving up our right to ever sell Ecosia (2018)
Same here. Both products are actually better than the ad-supported versions. Fastmail masked-addresses are great.
heeton··on Apple M3 Ultra
For AI workflows that's quite a lot cheaper than the alternative in GPUs.
heeton··on Zed now predicts your next edit with Zeta, our new open model
Right? If you don't like the tool, turn it off.

I find autocomplete _exceptionally_ useful. It's right in most of the simple tasks I'm trying to do and speeds me up a lot.

heeton··on Show HN: Printercow – Turn any thermal printer into an API endpoint
No, just computer notes. Currently on llama3.2 text-only 3B, running on an M3 Macbook Pro.

Accuracy is good for my limited use case (extracting context, giving me links and reminders).

It's not yet good enough (for me) at summarising larger notesets, it might miss out useful / pertinent things in a way Claude does not.

I'd also like it to be better at inferring partial context from audio transcriptions. But hey, it's an open source 2GB model running on my laptop, it'll get better.

heeton··on Show HN: Printercow – Turn any thermal printer into an API endpoint
My comment was that BPA is not used in thermal paper as a plasticizer, which that linked study was examining.
heeton··on Show HN: Printercow – Turn any thermal printer into an API endpoint
(I meant for the Pi software)

Edit: had a look at the firmware and it's not Nerves - but that's fine! I was just curious :)

heeton··on Show HN: Printercow – Turn any thermal printer into an API endpoint
Buy from a reputable seller for anything important, instead of amazon.

Or, there are apparently at-home testing chemicals that look simple to use. I haven't done it myself though.

heeton··on Show HN: Printercow – Turn any thermal printer into an API endpoint
That study looked at 6 similar plasticizers.

The alternative chemicals for thermal paper are totally different. That's not to say that they are guaranteed safe, but that study is inapplicable.

E.g. one type of paper claims to use Ascorbic Acid (vitamin C). No idea what else is in it of course, but it's not a BGA-analogue plasticizer.

heeton··on Show HN: Printercow – Turn any thermal printer into an API endpoint
Extremely shortsighted take.

I currently use a local LLM to scan my notes, meeting transcripts, todo list and calendar. I currently have an iPad that displays some items (e.g. if I have important personal tasks to do today that I might have forgotten) and I would love it to be printed out like this.

Nothing to do with generating novel text, it's just used as a flexible API to my existing text and items.

heeton··on Show HN: Printercow – Turn any thermal printer into an API endpoint
This is awesome! I have a very hacky prototype doing something similar, you've put way more effort into PrinterCow and it looks great.

What's the tech? (I'm crossing my fingers for Elixir/Nerves but I suspect that's still a bit niche)

Edit, I'm now signed up - though I'm struggling to find the install instructions for the RPi.

heeton··on UK's hardware talent is being wasted
Same. I'm in the UK, I've been a software dev for a long time (with forays into physical consumer products, not electronics/hardware).

I tinker with robotics, rpis, embedded tools, and the potential _power_ there is huge. But I never hear or see of jobs or opportunities (in the ballpark compensation of software).

heeton··on PostgreSQL Anonymizer
It allows updating the original data - https://postgresql-anonymizer.readthedocs.io/en/stable/stati...

> These methods will destroy the original data. Use with care.

heeton··on The origin of the cargo cult metaphor
> The thing is, most non-Americans dont connect master with slavery at all
heeton··on It's time to abandon the cargo cult metaphor
I agree.
heeton··on It's time to abandon the cargo cult metaphor
I personally thought it because of some exposure to that industry / video / AV over the years. But then I looked for some examples to confirm and easily found many.

Some decent examples here - https://news.ycombinator.com/item?id=26504086

Googling "Master Slave audio manual" has a bunch of examples. E.g. this manual from 1959 - https://www.worldradiohistory.com/Archive-Catalogs/Ampex/Amp...

heeton··on It's time to abandon the cargo cult metaphor
I'd wager good money that if you did a rapid-fire word association test on a spread of non-us english speakers, over half would say "slave" after master.
heeton··on It's time to abandon the cargo cult metaphor
> distracted us from dealing with the real issues Strongly agree with this. (And this kind of moral licensing in general. Ooh, well done for switching your toilet paper to an eco friendly version you were marketed on instagram, but why haven't you changed anything else in your life that matters).

But also, small things do have to change. If nothing changes, the status quo remains, and the status quo is stacked against many people. (Because of gender, race, culture, wealth, location, etc). It's easy to say "focus on the big things" but the small things can change along the way too.

heeton··on It's time to abandon the cargo cult metaphor
I get that the core issue was frustrating for some and I agree it felt a bit performative, but: I’m always amazed when someone tries to claim that this incredibly thin step away via a music term _with the same originating meaning_ somehow completely disconnects “master” from slavery.

Why don’t we spend energy on getting to the issues we actually care about instead of standing on shaky arguments and calling it a day. It’s lazy thinking.

heeton··on If we had the best product engineering organization, what would it look like?
The article uses “Internal Quality” which has a specific definition for them. And their definition of agility is not derived from the manifesto or Agile.

Indeed, they list Quality immediately followed by customer happiness (“loveability”) which is aligned with XP, the practice supported in the article.

The agile manifesto isn’t the only way to deliver good results in software.

heeton··on Ask HN: How can I learn to better command people's attention when speaking?
It's pretty much impossible to say without observing you. This isn't a technical question that can be answered over text (as much as everyone here will try).

Ask this question to some people you trust and simulate a conversation _in person_ to get feedback.

Contact me (bio) and I'll have a 10 minute call with you if you'd like.

heeton··on GitHub Copilot is now available for free
I personally love Cursor but never using prompts. I just use it's auto-complete and smart-tab features it saves me a tonne of manual typing. (I type fast, yet now find switching to a "manual" editor annoyingly slow).

I don't let it write blocks of code, but usually I'm ~5 keystrokes into a line change or addition and it can complete the rest. I also use a text-file todo in the same project to help it with context of what I'm trying to do.

heeton··on Map of GitHub
Lispaña is a really excellent name for a lisp country :)
heeton··on FizzBuzz in Powerchords
Woah, your comment is actually the decryption key for Blu-Ray disks.

(When combined with this one time pad over here...)

heeton··on Ask HN: How can I grow as an engineer without good seniors to learn from?
I agree. Writing well is _highly_ technical.
