Aromasin··on American importers and consumers bear the cost of 2025 tariffs: analysis
That is populism in a nutshell. It is anti-rationalism at its heart. There's no real ideology - that's how it applies to both Chávez and Trump, Corbyn and Orbán. People want to believe what feels "instinctively" correct, because the intellectual overhead of modern society leaves the majority of the population unable to deal with the reality that political and economic systems are incredibly difficult to understand without hours of study and thought. That is uncomfortable, so people rebel against intellectualism, because it's easier to be told lies through 30-second videos and feel well informed, rather than sitting through a 20-hour session that one might need to truly understand a niche of a niche. The more they read, the less they understand, so disengage from it altogether and go with their gut (designed for tribes of monkeys) because the cognitive overload is too much to bear.
Aromasin··on Show HN: I quit coding years ago. AI brought me back
I jumped mid-career, and there were a few places I started before diving into live hardware projects (which is the only way to go from student to practitioner).

Aromasin··on Show HN: I quit coding years ago. AI brought me back
I'd recommend a pivot to hardware. I'm in the FPGA sector, and vibe coding isn't a thing for the most part, simply because the determinism required doesn't lend itself well to LLMs. It's so incredibly easy to introduce a bug at every single step, and the margin for error depending on volumes is near zero. You're often playing with a single clock cycle of headroom. I've yet to play with a single LLM (Claude Opus 4.5 is my latest trial) that doesn't introduce a massive amount of timing errors. Most semiconductor IP is proprietary, top-level secret, code never leaves the building. The data to build good models just isn't there like it is for software and the open-source ecosystem.

In comms, they have something like a 1:4 ratio of design to validation engineers. Defence is slightly different, as it depends on the company, but generally the tolerance for bugs is zero. Lets not get started on the HF trading folks and their risk appetite!

There's a lot of room for software engineers. Most FPGAs are SoC devices now, running some form of embedded linux doing high-level task management networking. Provided you know enough Verilog to know your way around, you'll be fine. You're also in a space where most engineers I know are preparing to retire in the next 5-10 years, so there will be a panic which will ripple across industries.

Aromasin··on Ask HN: How can we solve the loneliness epidemic?
I think your comment about social acceptance in the UK is slightly off. It's person dependent. I would say my experience aligns closer with the 50% mark. It's a massive variant from person to person. I have friends that will turn up to anything, rain or shine, sickness or in health. Equally, I know people that would flake on a wedding because they stubbed their toe or the latest season of [insert meaningless reality show] came out.
Aromasin··on Find a pub that needs you
Worth noting the circle of "pubs that light on fire" and "flat roofed 1970s slum pub" almost entirely overlap. Nobodies setting fire to their thatched-roof pub from 1650 because of pub rates. They just change hands through the breweries every 3-4 years now.

Aromasin··on What a year of solar and batteries saved us in 2025
He mentions that he has a server. It wouldn't surprise me if that consumes the majority of that.
Aromasin··on JRR Tolkien reads from The Hobbit for 30 Minutes (1952)
I recommend trying to visit the ArdaCraft minecraft server. They're trying to faithfully recreate the LotR world at 1:58 scale, and I've spent some time attempting to do the whole walk over some evenings the past few months. It's absolutely incredible the amount of love and detail has gone into crafting the world.
Aromasin··on How will the miracle happen today?
Like all skills; practice. Push through the fear enough times that you learn to love it.

When I was in the military, we once had an exercise which consisted of our troop leaders dropping 60 of us in Edinburgh (Scotland) with nothing on our person except for a cheap film camera. We had to complete a list of challenges with different scores, that varied from "eat a free meal" to "play a hole at St Andrews golf course". We were picked up the following day (meaning we had to find a place to sleep the night) and had to debrief the group on what challenges we managed to complete with video evidence. To be honest, it completely changed my world view in a weekend.

We had guys who talked their way into an airfield, miles away from where we started, and convinced a random pilot to give them a spin in his private aircraft. One group managed to get the castle guards to let them fire the daily One O'Clock Gun from the top of Edinburgh castle. Another did manage to play the first hole of St Andrews (£340 a round, and a 2 hour drive away!). We had people crash a wedding, sew up a kilt, learn to play the bagpipes; it was carnage in the best kind of way.

All of that was done just by asking. At the start of the day, everyone was awkward and embarrased. By the end of day two, we all just wanted to see how much further we could take it. Turns out that sometimes all your inhibitions do is get in the way of a fun time and a great story.

Aromasin··on People who come off slimming jabs regain weight four times faster than dieters
The other option which people seem to shy away from is to simply embrace the act of feast and famine. I'll regularly go through binges, colloquially known as "Christmas" and "Summer", and to be honest I don't sweat about it. Either the fire is on and we're all celebrating with family and friends with a beer and a roast dinner, or the sun is out and we're having BBQ and cocktails doing the same.

If you can master the skill of dietary control, and go a month or two with really spartan fasting routine between celebration periods, life becomes a lot less stressful. I always enjoy watching Paddy Pimblett (UFC fighter well known for radical weight transformations:https://www.bbc.com/sport/mixed-martial-arts/62135535) bounce between weights, but always get in shape before a fight. It's a skill that only gets easier with practice.

Aromasin··on Project Patchouli: Open-source electromagnetic drawing tablet hardware
Honestly, just pick up the Art of Electronics - Horowitz and Hill. Spend some time working through that book. By the end of it, you'll have a better grasp of electronics than 90% of the engineers I've worked with, all who are EE bachelors/majors. It's a 3 month job at most, less if you do a dedicated hour a night. Then pick up some breadboard and parts, and build to your hearts content.

Making a working circuit is honestly very easy once you know the basics. Look inside a Made in China knockoff appliance, and you'll see that most things can be made from a couple of conponents and a microcontroller. Pull apart an old TV remote or bluetooth device, and look up the part numbers and what they do. There's not much to it. You have to remember that most of the stuff getting designed and built in South East Asia is done by people with zero qualifications. Electronics being "the thing that smart university people do" in the West is mostly a mental block, culturally constructed because people don't want their kids getting electrocuted so bombard them with constant threat of death if playing with electricity (which mostly isn't a worry anymore unless you're working with mains power).

The true discipline of Electronic Engineering is designing something that works for every eventuality and environment, with close to 100% reliability, at the very cutting edge of what is possible with the components we can afford while balancing physical and financial constraints. That's something which takes years of both academic study and industrial experience.

Aromasin··on The British empire's resilient subsea telegraph network
To think it was done even 1000s of years prior to that with just smoke and fire! Granted, the ability to communicate through the rain would be a necessity for the British.
Aromasin··on Nvidia just paid $20B for a company that missed its revenue target by 75%
The FTC requested significant increases for technology and economic analysis for FY2025 ($535M), but was given a static budget with plans to cut by 11%. FTC chair Ferguson reduced staff from 1,315 to 1,221 and aims to reach around 1,100 through attrition to align with lower budgets.

Aromasin··on NIST was 5 μs off UTC after last week's power cut
I worked at Altera (FPGA supplier) as the Ethernet IP apps engineer for Europe for a few years. All the big telecoms (Nokia, Ericsson, Cisco, etc) use Precision Time Protocol (PTP) in some capacity and all required clocks to be ns levels for accuracy. Sometimes as low a 10ns at the boundary. Any imperfection in the local clock directly converts into timestamp error, and timestamp error is what limits PTP synchronization performance. Timestamps are the fundamental observable in PTP. Quantization and jitter create irreducible timestamp noise. That noise directly limits offset and delay estimation. Errors accumulate across network elements and internal clock error must be much smaller than the system requirement.

I think most people would look at the error and think "what's the big deal" but at all the telecoms customers would be scrambling to find a clock that hasn't fallen out of sync.

Aromasin··on How getting richer made teenagers less free
It's common in the UK to work from the age of 13 or 14, depending where you live. I worked in the Post Office across my road at 13, every Wednesday evening and Sunday afternoon, in 2009. Most of my friends had part time jobs working in retail while at school. I was behind the pub bar at 16 slinging pints.

The (possibly completely incorrect) impression I get from speaking with Americans I know who have moved here, or I work with, is that nobody really works until they get to college unless it's a paper round or it's at your parents business. It almost goes without saying then that most people would be pretty infantile if they don't start work until they're almost mid-20s.

Aromasin··on If You Quit Social Media, Will You Read More Books?
My progression was something like:

Video Games > Social Media > YouTube > TV > Reading

I had to cut quite a few things out of my life before I defaulted to books, because all of the prior activities tapped into my brains inherent desire for stimulating, low effort consumption. Reading is quite often hard, boring, or difficult, but generally more rewarding in the end. I retain more useful information, explicitly because it is more difficult and my brain denotes it a higher reward value.

Aromasin··on What will enter the public domain in 2026?
I think would diminish independent author rights. Quite often, a novel will become popular only decades after publishing, and I think the author should be able to profit on the fruits of their labour without wealthy corporations tarnishing their original IP, or creating TV shows and the link with no reperations to the creator.

Fantasy book are a good example. A Games of Thrones was first released in 1996 but had middling success. It was only after 2011 that the series exploded in popularity. Good Omens main peak was ~15 years after release. Hell, some books like Handmaiden's Tale were published in 1985 but only reached their peak in 2010.

IP law was originally to protect artist and authors from the wealthy, but now it seems to have the opposite intent.

Aromasin··on Arthur Conan Doyle explored men’s mental health through Sherlock Holmes
I wouldn't be surprised if many of those who upvoted this did so because the agree with the sentiment in principle, not because they read the article and appreciated the contents.
Aromasin··on How the UK lost its shipbuilding industry
The UK faces serious structural problems (low productivity, weak investment, stagnant wages, and an over-centralized economy), but none of that automatically translates to terminal decline.

In the 1970s, the UK was dubbed the “sick man of Europe,” reliant on IMF support and wracked by strikes, but it entered a multi-decade period of renewed growth and influence before Brexit and the COVID-19 crisis.

The US in the 1970s seemed finished: stagflation, oil shocks, industrial decay, humiliation in Vietnam, a hostage crisis, and a sense of lost purpose. Paul Kennedy, Robert Gilpin, Lester Thurow, etc., all wrote about the “limits of growth” and “imperial overstretch,” yet it rebounded to global dominance by the 1990s. The 1970s “decline” narrative didn’t age well.

Japan in the 1990s was declared “done” after its asset bubble burst, and the “lost cause” or “lost decade” became a cliché. Yet it remains the world’s third-largest economy, a technological leader, and a model of social stability, public safety, and industrial competence. It has declined maybe in relative GDP growth terms, but in living standards and quality of life, Japan has done remarkably well.

Britain still has world-class higher education and research sectors, a strong legal system and institutional stability, cultural and linguistic global reach well beyond its economic means, deep financial markets, and fantastic renewable energy potential. The current doomism, I believe, all comes from public overexposure to tabloid news, which permeates every part of our lives through social media. Scare-mongering has always been the most profitable form of journalism, and articles about the UK's decline make addictive reading for much of the populace.

Nobody seems to want to read articles about how the UK produces roughly 15% of the world’s most highly cited research with less than 1% of the world’s population, or how it’s the global leader in genomics, vaccine development, and life sciences (the Oxford/AstraZeneca COVID vaccine was one of the fastest developed in history), or how it is Europe’s AI hub, home to DeepMind (Google), Stability AI, and dozens of AI startups, with London often ranked second globally after Silicon Valley for AI investment. They tend to write very little on how it builds about 40% of the world’s small satellites, or the fact that it’s a world leader in offshore wind generation capacity - #2 globally after China - or that it has cut emissions faster than any G7 country since 1990 while maintaining GDP growth. There’s very little commentary on the success of the creative industries (film, TV, music, design, advertising), and how they’re a £100+ billion sector and among the fastest-growing parts of the economy, or how the UK is Europe’s largest video game exporter, with studios like Rockstar North (GTA), Creative Assembly, and Frontier.

There are endless positive growth stories happening in the UK, but unfortunately, while we’re still leaders in many things, we also pioneered (in partnership with Australia and New Zealand) toilet-paper journalism in the likes of The Daily Mail and later The Sun, which started the mass-market, sensationalist, personality-driven style of journalism that became the global tabloid model. It invented the genre as we know it today, still dominates it, and exported its techniques globally (blame the UK and Rupert Murdoch for the success of Fox News).

Radical optimism is quite difficult as a British person, as dour cynicism is our culture’s resting state, but I don’t see the signs of a failing empire personally.

Aromasin··on How I am deeply integrating Emacs
You can but that doesn't neccesarily mean you should.

I tried it for a while, after seeing my Eve Online friend skipping through tasks at a rate of knots without any mouse movement. My god the amount of tab pressing I had to do to get anything done was crippling. I might have to jump through 15 times to get to something that would take me less than a second to click.

Aromasin··on Minecraft HDL, an HDL for Redstone
The only reason I ended up persuing Electronic Engineering at University, or eventually becoming an FPGA Engineer, was because I spent way too many hours playing with redstone in Minecraft as a teenager. Seeing a Verilog compiler for Minecraft is like seeing my career come full circle.

Aromasin··on Jaguar Land Rover hack cost UK economy an estimated $2.5B
I believe this used to be a thing absolutely, but something seem to change ~2012 where they seemingly went from some of the least reliable luxury cars on the market to some of the most - but the hangover from 50 years of unreliability will plague them for years to come I'm sure. The tests and standards they need to pass to get out of the design and manufacturing departments are pretty staggering now (compared to the tire kick tests they used to), and general reports from mechanics in forums I frequent and people I meet at car meets is that a modernish JLR will keep on ticking provided they're serviced every year.

Honestly, I've been eyeing up a 2015 Jaguar F-Type for a while now. It was a £85k car depending on trimming that you can pick up for £20k now with a V6 supercharged VS. An old-school style coupe, without all the modern ADAS beeping and handholding, that will just plod away if you look after it seems very appealing.

Aromasin··on Warming climate–not overgrazing–is biggest threat to rangelands, study suggests
There's a guy in New Zealand I met who spent the last 30 years rewilding what was previously agriculture herding land. He said his biggest frustration with land owners wasn't the push back on what he was doing, but the ignorance as to what could be achieved. Every single person he spoke to told him explicitely if the land was left to go to nature, it would be nothing but gorse and it was a waste of good grazing land. The actual result was a return of native rain forest with levels of species diversity that were almost 60% of untouched rainforest, which is pretty incredibly in such a short amount of time.

This is the guy for context - it's a very interesting video that really highlights the impact that over-grazing has: https://www.youtube.com/watch?v=3VZSJKbzyMc

Aromasin··on Imgur pulls out of UK as data watchdog threatens fine
What one might contribute to malice can normally be attributed to ignorance. I think the political class in the UK is just completely bifurcated from the public (not as much as the Tories were, but more than I though Labour would be), such that every decision senior Labour leaders are making is lauded in progressively smaller circles they keep and they're oblivious to the reality of the situation. They just don't feel the condemnation of the general public. I think current Labour genuinely thinks their popularity is higher than it is polling, and that they're doing what people want.

To caveate this, I am a Labour member (with the goal of advising tech policy such that they don't send our tech industry off a sharp cliff). I've spoken to a few in the cabinet now about growth and industrial policy, and there's no appetite for engagement outside of their think-tanks. I go to the conferences today, and in contrast to the Tory government days where the main topic of conversation was "what do people want" and "how do we gain seats in the election", it's now all navel-gazing about how "well" their policies poll (vs how well the party does, as if they're the same thing). It's baffling how out of touch the current power brokers are regarding the danger Labour are in. There's rose-tinted glasses, and then there's obsidian-tinted horse blinders.

Aromasin··on Trees on city streets cope with drought by drinking from leaky pipes
We already have this data in a way, from cities where there is no running water and people rely on bottled water for drinking and washing.
Aromasin··on Little-known leguminous plant can increase beef production by 60% (2022)
Humans are quite capable of digesting a diet rich in legumes just like all our other close relatives in the great ape kingdom. They subsist on a 85-99% plant based diet, primarily of fruits, nuts, and seeds. We have clearly adapted to eat more meat as our bodies changed to master running and throwing for hunting, but we are still a variant of great apes at the end of the day.
Aromasin··on Little-known leguminous plant can increase beef production by 60% (2022)
Gut biome is important for legume consumption. The first few months I went to a plant based diet my digestion was hell. At some point I reached a turning point though, and my gut health became even better than before. My flatulence was so much worse when I was eating meat regularly - often room clearing.
Aromasin··on Shallow water is dangerous too
I surf a lot, and I've lost count of the amount of times I've had to save people from a riptide. They're always completely exhausted, barely keeping head above water, and minutes from getting pulled out to sea with no energy left to swim around the rip and back to shore. I pulled out a couple on deaths door on their honeymoon just a couple weeks ago - that could have crippled their families. It's frustrating the lack of awareness people have around the sea. Unless you know the shore you're swimming on intimately, or the sea is flat with no swell, there's no guarantee you'll be able to fight the sea if you're further out than up to your waist in water.
Aromasin··on Vanishing home field advantage in English football
In Union, many of the popular leagues are international clubs level. For most of their history, they were split into Southern and Northern hemisphere leagues. Recently that shifted, and the South African teams joined the United Rugby Championship which is European (Ireland, Italy, Scotland, Wales, and before Top 14 became preferred, France). This was because, despite the historical significance, the time zone difference between the South African and Australia/New Zealand teams were too severe. Now South Africa is in the United Champinoship, they only play in a +/-2 hour difference in terms of time zone.
Aromasin··on Tokyo's retro shotengai arcades are falling victim to gentrification
I often watch travel vloggers visit these places and you can't help but notice that all the vendors are also in their 70s or older, and they run them on their own. With no generational hand-over these places are doomed not matter how succesful or not they might be.
