Aromasin··on Open Source and FPGA Maker Board for Networking
Agreed. They are using an Cyclone 10 GX - that's over $250 for a part from 2017...

If the restriction is wanting low price to suite the FPGAs open-source low-budget market, they'd be better off using a Lattice Certus-NX or something. 5Gbps SERDES on that for ~$40, or better yet a CertusPro-NX with 10Gbps SERDES for ~$70. Altera and Xilinx are just throwing away the sub-100K-LUT market to Lattice at this point, yet people are still building systems out using these expensive, antiquated parts. That's shelf pricing too - go through a distributor and it'd be 50% of that price!

Aromasin··on Open Source and FPGA Maker Board for Networking
You can absolutely do this using something like a CertusProNX from Lattice (I much prefer it to the Polarfire), mounting an SFP/SFP+ cage onto the FMC connector of the board, and wire their transceiver lanes to the FPGA SERDES pins. HiTech Global has a 4-port SFP/SFP+ FMC module. I believe there are also QSFP mezzanine cards but I haven't looked much into that. ISI or Trenz probably make something.
Aromasin··on The FPGA turns 40
Absolutely, but I quoted shelf price. Volume pricing can be anywhere between 30-80% less than that. Agilex 5 equivalent is ~$900 and much the same for the Ultrascale+ equivalent, so Lattice is the most competitive on cost.
Aromasin··on The FPGA turns 40
CertusPro-NX has I/O Configuration in about 4 ms and full fabric config within 30 ms (for ~100 K logic cell device). Certus, full‑device configuration within ~ 8 ms.

Lattice make some really cool devices. Not the fastest fmax speeds, but hell if the time to config and tiny power draw don't half make up for it.

Aromasin··on The FPGA turns 40
Part of why Lattice Semi has been so successful in recent years is they've broken the paradigm slightly in that their FPGAs are much most cost-effective, while still coming with all of the things we expect of FPGAs. Lots of high-speed IO, half decent software, and a pretty broad IP portfolio. Something like the Certus-NX comes in at ~$5 at the 17k LUT count, and Avant only ~$550 at the 600k LUT mark. That's almost a 1/4 or more of what the equivalent Xilinx or Altera device goes for. There's very little licensing cost too, which make them really appealing. I see them going into so many designs now because they can scale. You'd have to be making 100Ks+ of boards to justify the ASIC expense when there's a commodity product like it.
Aromasin··on TI to invest $60B to manufacture foundational semiconductors in the U.S.
FD-SOI fabs are lacking. It's a planar transistor technology used frequently in very low power/thermal devices with small packages and with a high SEU tolerance. Lattice semiconductor use them in their FPGAs, which are the lowest power draw FPGAs on the market at the moment, with a really flat power curve all the way up to 125C. They're used everywhere in A&D and industrial, as root-of-trust devices on servers, and are the largest FPGA manufacturer by volume.

Currently it's fabbed in France (STMicro), Germany (GF), and South Korea (Samsung). No plans to onshore that in the US.

Aromasin··on OpenSERDES – Open Hardware Serializer/Deserializer (SerDes) in Verilog (2020)
I work in the FPGA industry, and it's a running joke that the best device manufacturer at any one time if the one with the best SERDES and PHY team.

You can have the best fabric in the world with all of the best IP, but if you can't get information on the device and off again to do anything useful, then what's the point (looking at you Intel F-Tile).

Aromasin··on The effect of deactivating Facebook and Instagram on users' emotional state
The problem is, I haven't used it in 8 years, so there's no way to know my preference. The email is also not tied to any other accounts than perhaps a few browser video game accounts from my youth (miniclips, runescape and the like). My guess is that it fills the feed with sexualised content because it's the most popular kind, and eventually repopulates it depending on subsequent follows. The problem is I only follow friends and family, not celebrities, so that would prove difficult to do.
Aromasin··on The effect of deactivating Facebook and Instagram on users' emotional state
Eh, I'd disagree on the Instagram front. If you look at the reels section, where most spend their time, it's just a more deplorable Tiktok. 80% of the content on there is soft core porn advertising one OnlyFans girl or another. The other 20% seems to be brain rot memes. I reinstalled it recently after 8 years of not having it, and immediately deleted it.

Mines' the same. My local firewall blocked the site when the YouTube embbed tried to play, and when I switched to my work VPN it blocked the domain altogether.
Aromasin··on 300-year-old Polish beech voted Tree of the Year
I've visited it in person, and it's utterly bizarre. You emerge from a monoculture pine forest (you can see the straight trees in the background of the photo) into a glade with the most amazing mix of ferns and moss that aren't found anywhere else in the forest. It made me really emotional to be honest. Scotland is beautiful in its own way, but to be frank it's mostly farmed woodland or shep pasture now. The true wilderness is few and far between, so seeing something that old with so much life bubbling around it, so then merge into a barren pine farm, made me deeply upset.
Aromasin··on Designing Electronics That Work
This seems entirely more digestible than AoE though. Don't get me wrong, I've read that book probably 6 times over in my life - it's fantastic- but it's a university text book. This new book seems aimed at simply getting a product out the door, which is a different but useful niche.
Aromasin··on Finland's National Allergy Program Successfully Reduces Allergic Diseases
It's probably a bit of one, a bit of two. Despite spending everyday in the garden growing up, I've always struggled with allergies and they've changed throughout my life. I was deathly allergic to tomato's and eggs as a child but grew out of it around 11-12, became very allergic to pollen and pet dander at 5, which is now life long, and recently in my late 20s become allergic to hazelnut and some other foods I've yet to pin down (my mouth comes up in hives with no rhyme or reason while eating occasionally). I've also developed oesophagitus in my late 20s, to the point where I choke on foods daily unless chewed to a pulp before swallowing.

To me, it seems the parasite theory makes sense in tandem with hygiene. Some people by upringing become predisposed to allergies, while others have genetically as a result of humanities constant fight against intestinal worms. As our genetic profile changers as we age, so does how our bodies express said genes which would be designed to fight something we no longer have.

Aromasin··on America Is Missing The New Labor Economy – Robotics Part 1
"Just decided" =/= decided today. They decided months if not years ago, after months of negotiations with local authorities. Don't look at plants opening now to judge the current administration. Look at it 2 years from now.
Aromasin··on US Ends Support For Ukrainian F-16s
The biggest win the Republicans and billionaire class ever had was convincing the American public that left == liberal. It's not. Blue hair, trans flag, black lives matter, pro-palestine, etcetera; these are socially liberal stances. "Left" doesn't mean any of these things for the rest of the world in a conventional sense. Left means unions, workers rights, socialism or sydicalism; generally, power to the workers/99%/people rather than the capatilists/monarchists/regime.

Americans should continue to conflate socially liberal and economically left-wing at their own peril.

Aromasin··on How the U.K. broke its own economy
Thatcherism is shortermism manifest. It's the same attitude that plagues the corporate world - focusing on next Quarter profits rather than the next 20 years. It leaves nothing left at the end but a broken state and more billionaires than we ever had medieval kings, while the rest of us slide back into Dickensian poverty, be you doctor, engineer, soldier, or social worker. We traded state wealth (sold off massive amounts of passive income generating assets like housing and utilities) for short term economic GDP growth in the 90s and early 00s, and now we brunt the cost of it because our passive income has gone. The Tories were more worried about re-election than they were keeping the middle class alive.

Our utilities and infrastructure are now drain us for every penny we're worth, and guess what? They're largely owned by other countries now. Our train networks, our energy companies, our communications, and so on, go to pay the French/Chinese/Scandinavian/etc government's. Somehow other countries manage to make profit on state asset; something which Thatcher never had the capacity to do. That's not considering the private industry, which makes £MM in profit, pocketing it instead of reinvesting it in the state which is the primary mandate of public ownership. Individuals abroad or in the 0.1% profit make money from our state, while the rest of the country withers.

Aromasin··on How the U.K. broke its own economy
Turns out Thatcherism only works as long as the state still has assets to sell off. The delusion that assets would stay in the hands of the working and middle class, and not end up with the wealthy inheriting class, has to be one of the biggest political failures of our government on the modern era. It's lead to the possible death of the Conservative Party if they fail to fight off Reform and the Liberal Democrats.
Aromasin··on Inheriting is becoming nearly as important as working
This seems backwards to me. Labour can leave; someone can get on a plane in the UK where they get taxed 40%, and arrive in Dubai where they're taxed 0. Their buildings and assets can't come with them however. Capital that's not ethereal assets like stocks, shares, credit, etc, can't be moved. If you want to leave the country you need to become liquid, which means you sell off your assets and whoever is left in the country gets to buy them at cheaper rates.

The issue is when we allow people who do not live or pay tax in this country to make profit on assets in said country. A landlord who lives in the Cayman Islands should not be able to collect rent on UK assets while not paying the UK government tax in turn.

Aromasin··on Inheriting is becoming nearly as important as working
Of course they do. They've built entire careers around the concept that the whole economy can be models on N=1. Inequality doesn't fit into their models, so they dismiss it out of hand because otherwise the 20+ years of their life they've spent devoting to their craft proves to be no more useful than a horoscope.
Aromasin··on Inheriting is becoming nearly as important as working
Okay, so a lot of ~£40k a year salaries (outside of medicine and finance) to afford a £400k house when your parents might have had a £20k salary to afford an £80k house? There's a real disparity when you consider what they did too. If your parents are anything like mine, they were in the pub 4 days a week, drinking and eating with friends. I can managed that just a few times a month. Wealth compared to income from my experience is significantly lower by .lost metrics.
Aromasin··on Local social spending and political dissatisfaction of the economically deprived
We've seen for centuries what bored oligarchs do - they lead crusades across nations states for one bullshit reason or another with an legion of people who need to work with them for money, entering into indebted servitude agreements. They get bored and go to war. Apparently building and inventing isn't another - I suppose because most of them are incabable of doing that due to a lack of talent. It's not so fulfilling being the moneybank with other people do the hard and interesting work. Probably why billionaires like Gates are midly normal compared to most - he's talented enough to do the building himself if needed. Same can't be same for Musk and Trump.
Aromasin··on Broken legs and ankles heal better if you walk on them within weeks
An ankle arthroscopy leading to debridement of the joint. I have some bone or scar tissue that is causing impingement, meaning my tibia doesn't glide along the top of the talus like it should do. There's little I can do to fix the arthritis in it now, but I can at the very least free to some movement such that the rest of my body isn't limited by my lack of mobility.
Aromasin··on Broken legs and ankles heal better if you walk on them within weeks
I can certainly attest to the consequences. I unfortunately shattered my ankle and broke my back simultaneously, which meant I didn't walk on my ankle until 6 months after the incident. As such, even 10 years later my ankle is a constant irritant to me. I have next to no dorsiflexion beyond a straight leg now. No ankle mobility means persistent pain in my hip, knee, and back on that side, and I'm only 29. God bless the NHS for saving my life at the time and not charging me a penny, but despite my best efforts I can't get any further treatment now to improve the flexion. I'm counting down the years until I can finally afford further surgery and get some quality of life improvements.

Aromasin··on US government struggles to rehire nuclear safety staff it laid off days ago
No, they don't. Most people don't seem to get beyond 1st order thinking. At best, it's cause and effect - 3rd/4th/5th order effects are just not computable. If X then Y is the best they can manage.

Some might say he was just stretching his neck, but personally I love an electronic music gigs, and I've seen that behaviour enough times before. He's not quiet about his ketamine usage either (not an upper per-se, but close to an alcohol-like hallucinogenic from my experience).

Aromasin··on US government struggles to rehire nuclear safety staff it laid off days ago
The European Payment Initiative, the EPI, abandoned its plans for a card scheme and decided to focus on an account-to-account instant payment solution (A2A) for all kinds of use cases, all through a wallet. There is an interesting synergy here with the European moves to develop a common digital identity service and euro-wallet infrastructure.

They're not just trying to get rid of the US middleman, but the middleman altogether.

Aromasin··on Dust from car brakes more harmful than exhaust, study finds
I recently just sold on my old car, as I'm getting a company one. Figured it'd be some estate or coupe with good motorway mileage. Nope. Instead it's an SUV, which I've routinely given people shit for, for the last few years. The things are a plague that are starting to infest even corporate motor pools, and this is in the UK of all places, where the country roads are more often than not the width of a small hatchback.
Aromasin··on The return of the buffalo is reviving portions of the ecosystem
Over a range of the entire United States? Yes, absolutely. The grazing land is now a fraction of what it was pre-colonialization, and much more highly concentrated. Instead of giant herds moving from one pasture to another, they're kept in conparitively tiny cattle reservations where they overgraze leading, to these barren dustbowls.

The cycles of graze, move, graze, move, with seasons where plantlife had time to recuperate, are long gone. It's graze, graze, graze, until there's nothing left and the herd die out or are moved elsewhere to do the same.

The problem with this issue is it's complex in a bell curve nature. With humans in the mix, we take it to an extreme - it's either cattle land or its not, and there's no room for a compromise because cattle can't graze on cropland, or through urban/industrial areas, so they get put on lots too small for them and cause immeasurable ecological damage in the process.
