Résumé/CV: https://resume.peterolson.dev

Email: See résumé.

I graduated from the University of Minnesota in May of 2021 with a Bachelor's in Environmental Engineering. I realized my passion for programming while writing MATLAB code to model pollutant degradation in hydrologic systems.

After graduation, I enrolled in Genesis 10's Dev 10 Java developer bootcamp, where I learned to build containerized full-stack applications that run on AWS cloud infrastructure.

I'm presently a backend Java dev with 3 years of experience working on Spring Web Flux microservices and AWS cloud infrastructure in the financial services industry.

My current role has provided invaluable experience in navigating and contributing to established codebases, fostering a deep understanding of legacy systems and their maintenance. I've honed my collaborative skills by working closely with diverse tech teams, from initial problem identification through user feedback, to collaborating with architects to design and implement solutions that spanned multiple departments. This process involved not only technical development but also clear communication and thorough documentation. Additionally, I've taken on the responsibility of training new staff, ensuring they are equipped to contribute effectively, and I consistently address user issues, demonstrating my ability to handle technical communication and provide comprehensive support.

There’s a whole discipline which does nearly that, though they do not use this style of agent based model.

Generally agent based models have numerous parameters which can take many values (endowments, preferences) and the models don’t themselves give any guidance about how to set the parameters. Theory can give limited guidance (eg., that function is concave, this parameter is negative). Sometimes we have experimental data though its generalizability beyond the lab is uncertain.

What you want to do to create a scientific macroeconomics is to work backwards from the data you see in the economy (aggregate consumption, investment, etc.) and how you know the aggregates were generated (via the behavior of a lot of individual agents), and an equilibrium assumption to recover the parameters.

If you know the parameters of the model you assume, you can then simulate interesting counterfactuals. (And yes you assume the model - a “full” model including “all” of the individual endowments and parameters you can think of is completely intractable. You have to simplify.)

You’ll never get that out of the author’s computer game.

If you want references to the macro literature it’s enormous and I can provide them.

With ATProto, you don't have to implement most of the federation. For your project specifically, it would be called an "AppView" in atproto lingo. You would...

1. store public data in the user's PDS (an api call instead of a db call)

2. listen to the firehose for records created by other frontends to your AppView (optional, especially early on)

Otherwise, it would be quite similar to any other social media site with mobile apps, a backend, and a database

I worked on at both companies on drivers. The programming models are quite different. Both make GPUs but they were designed by different groups of people who made different decisions. For example:

Nvidia cards are much easier to program in the user mode driver. You cannot hang a Nvidia GPU with a bad memory access. You can hang the display engine with one though. At least when I was there.

You can hang an AMD GPU with a bad memory access. At least up to the Navi 3x.

One of the nifty things about the target being JavaScript was that I didn’t have to finish it before I could run it—it was the sort of big library where typical code wouldn’t use most of the functionality. It was audio stuff, so there were a couple of core files that needed more careful porting (from whatever in Java to Mozilla’s Audio Data API, which was a fairly good match), and then the rest was fairly routine that could be done gradually, as I needed them or just when I didn’t have anything better to focus on. Honestly, one of the biggest problems was forgetting to prefix instance properties with `this.`

I ask people to unplug their Ethernet cable and tell me the colors they see on the wires all the time.

I don't care, of course. But they'll happily do that, where if I ask them to verify if the cable is properly plugged in, 99% of them will just say yes without so much as glancing in the cables' direction.

mostly, the software in printers/scanners and Adobe's Photoshop alikes is looking out for the "EURion" pattern.

https://en.wikipedia.org/wiki/EURion_constellation

That is not to be confused with (dynamical) and non-visible tracking info on printed sheets, which in fact can have everything coded in. By that, even 1-bit printouts can be identified up to the source. If the printer model and #salt is printed alongside, the prosecution has evidence for the cases the printer involved.

I made it! 90 t/s on my iPhone with llama1b fp16

We completely rewrite the inference engine and did some tricks. This is a summarization with llama 3.2 1b float16. So most of the times we do much faster than MLX. lmk in comments if you wanna test the inference and I’ll post a link.

"Good enough" by what metric? I mean all art is subjective.

I agree your argument based on supply and demand. But, my point was that the creative adventures are not rewarded well enough in our system, and somehow things that are terribly meaningless like ad-optimization attracts so much revenue that companies don't know what to do with. This imbalance is upsetting.

There is an SDG vocabulary to link problems and solutions with: https://unsceb.org/common-digital-identifiers-sdgs :

> The common identifiers for Sustainable Development Goals, Targets and Indicators are available online. The portal is provided by the UN Library, which also hosts the UN Bibliographic Information System (UN BIS) Taxonomy. The IRIs have also been mapped to the UN Environment SDG Interface Ontology (SDGIO, by UNEP) and to the UN Bibliographic Information System vocabulary, to enable the use of these resources seamlessly in linking documents and data from different sources to Goals, Targets, Indicators, and closely related concepts.

The UN SDG vocabulary: https://metadata.un.org/sdg/?lang=en

(1) It's incorrect to assume that the content published on HN benefits only the VCs, and none of the other participants.

(2) This particular post is an interesting data point in the research of what the current crop of LLM-based tools is capable of. It reads a bit like a Windsurf ad; I would like more details on how the technical side of the development panned out, what were the problems and where, how were they overcome, etc.

(3) The parent comment reads as a somehow funny mix of socialist "anti-greed" agenda and frowning upon the fact of sharing knowledge and experience freely.

On one of my internships there was a small handheld radio floating around the office. I changed it to some local AM jazz station, set it to the lowest possible volume (such that it was barely audible), and hid the radio inside another interns desktop. I told the other interns about it, and we agreed that whenever he asked anyone if they could hear music, that we would tell him we couldn't hear anything.

At first he seemed mildly annoyed but mostly ignored it. You couldn't always hear it depending on what song was playing, so that helped keep it hidden for a while. Fast forward one week, we came back from lunch to find that the guy had disassembled almost everything in his cubicle before finding it. He angrily held up the radio and called us all jackasses. I have a little chuckle every time I remember this!

It does seem like the effects (perhaps both positive and negative) increase when we go from individual artists copying the Ghibli style, to something like Thomas Kinkade Studios reproducing paintings at industrial scale, to the current endgame of Ghibli-as-a-Service, available on-demand via ML models trained on the original works.

Artists don't seem happy with the pipeline of companies digesting their work, usually without permission, into ML models that are used to generate thousands of imitation works. Perhaps it is the issue of commoditizing someone's painstakingly developed individual style, or simply of competing with the artists themselves with realistic commissions that can be generated rapidly at almost zero cost.

I think the most crucial takeaway for me is that NTSB finding of how often this was almost happening for over a decade. That's guilt by inaction at that point. I understand that some flights need the security of being un-broadcasted, but I struggle to think they happen so often. It feels like the FAA is really saying that they're raising the bar for being able to turn off the ADS-B which I agree with completely. Too bad it's 10+ years too late.

What about muon imaging?

What about Rydberg sensors for VLF earth penetrating imaging, at least?

From "3D scene reconstruction in adverse weather conditions via Gaussian splatting" https://news.ycombinator.com/item?id=42900053 :

> Is it possible to see microwave ovens on the ground with a Rydberg antenna array for in-cockpit drone Remote ID signal location?

With a frequency range from below 1 KHz to multiple THz fwiu, Rydberg antennae can receive VLF but IDK about ELF.

IIRC there's actually also a way to transmit with or like Rydberg antennae now; probably with VLF if that's best for the application and there's not already enough backscatter to e.g. infer occlusion with? https://www.google.com/search?q=transmit+with+Rydberg+antenn....

I tend to use testssl.sh (https://testssl.sh/), are there any major benefits to sslyze?

I’ve just tried running it a moment ago to compare. The output isn’t as organised/readable and it includes several tracebacks for failed checks (tlsv1.1, tlsv1.2, tlsv1.3, and compliance against Mozilla TLS configuration).

Always open to different tools but it seems testssl.sh is currently more complete

The same thing happens in organic chemistry. You're graded by your yield. If you put 10 units of A in, cooked up 9.9 units of product B, great job! But if it's 0.01 units, good luck, or 0, heaven save you. of course, they might give you 15 units of A to begin with, you're only to use 10. So at the end of it, you get 9.9 out out of 15 in, and say you only put 10 in. Of course, if you get 14 units of product out of "10" in, you just cut down the product accordingly. I'm pretty sure with organic chemistry lab being a core pre-med course, that this might be more the norm than the exception.

I’m not a tech expert, just someone who got fed up with VPNs dropping connections all the time. So, I teamed up with some developers to create Credant, a decentralized mesh network tool that’s supposed to fix that mess. It’s built on solid tech (WireGuard, I think?), but I’m not the one to explain the nerdy stuff – we’ve got a whitepaper for that on our site. My job’s simpler: I’m giving away 100 free licenses for a year. If you’re into networking and want to try it out, please jump in and tell us what sucks or what works. I need your help to make it better!

I didn't say it wasn't interesting, but I'll take the bait: the article is light on details and misleading.

Light on details: the article is almost 3000 words, filled with vague and low-effort content: a lot more "We're so big and global!" and not nearly so much "Here's the problem we faced because we're so big and global, and here's how we solved it."

Misleading: they use the word "democratizes" twice: "we have crafted a scalable solution that ... democratizes access to advanced production tools across the globe" and "we’ve taken a bold step forward in enabling a suite of tools inside Netflix Content Hub that democratizes technology: the Media Production Suite" -- do you really get to say "democratizes" when you're describing an in-house system?

The problem with spam isnt the content, its the quantity.

Lots of spam emails are for genuine services. But its generally accepted that because the speech is unwanted and the quanity of it lowers the quality of the platform, that its fine to filter it off.

Free Speech absolutism should incorporate it, but doesnt. (Which sort of indicates its mostly about broadcasting their opinions rather than being in favour of all speech)

I'm an industrial physicist, and the post put a smile on my face. And indeed, it's not fiction. It's a blast. You will go through times like this, I guarantee it.

I've been wrestling with a cantankerous experiment for a couple of weeks. It produces reproducible results, but they don't make sense, and the work is not in a domain where discovering new physics by accident is likely.

I would imagine as in the professional world, there are certain school jobs that attract sociopaths/narcissists/psychopaths. Yes, I’m talking of course about vice principals. My elementary, middle and high school principals were very nice. The VPs were mostly unapproachable hardasses. It may have something to with the principal vs vice principal responsibilities in the U.S. I’m not sure how it is elsewhere in the world.

Multiple files with a single LLM call.

I have a prompt which works for a single file in Copilot, but it's slower than opening the file and looking at it to find one specific piece of information and re-saving it manually and then running a .bat file to rename with more of the information, then filling out the last two bits when entering things.

Thank you! Generally Turso has focused on operating more like a traditional network attached backend. Although that has changed recently with libsql and embedded replicas. I think at this point the main delta is they use traditional wal based physical replication while Graft is something new that permits trivial partial replication. Also, Graft is not exclusive to SQLite. It’s just transactional page addressed object storage with built in replication. I’m excited to see what people build on it.

There's this old amusing book The UNIX-HATERS Handbook[1] in which Dennis Ritchie has written a funny "Anti-Foreword."

"...Your sense of the possible is in no sense pure: sometimes you want the same thing you have, but wish you had done it yourselves; other times you want something different, but can't seem to get people to use it; sometimes one wonders why you just don't shut up and tell people to buy a PC with Windows or a Mac. No Gulag or lice, just a future whose intellectual tone and interaction style is set by Sonic the Hedgehog. You claim to seek progress, but you succeed mainly in whining..."

This seems quite relevant to Klien & Thompson's new work, which is basically advocating for and co-opting many of the core economic ideas of the current administration; ideas that would be difficult to imagine anyone would else in the government class would be qualified to out-execute them on when the rubber actually meets the road, despite their reservations and the differences they have at the margin. End of the day, somehow they wish they owned the agenda, which is understandable: they are peddling an ideology and it is difficult to see the competitive one win on merits.

Set aside the cleanup for a second: for pure power generation, nuclear is the ultimate clean energy source. Massive amounts of power, extremely cheap when amortized, liked by all political factions (except old-school '70s-era environmentalist liberals), a great source of jobs from blue to white collar, and no pollution or greenhouse gas emissions.

Turning back to nuclear waste: it's a solved problem. At least, very good solutions already exist. For example, see WIPP in New Mexico [0].

As with all energy sources, there is no perfect, one-size-fits-all solution: use a diverse set of energy sources based on what makes sense for the specific locale you're targeting. Nuclear will make sense for some areas (perhaps dense metros), while solar would make sense in others. Geothermal and natural gas as well.

We live in the future. Act like it!

And what they say in the industries that need to take this ultra seriously (Banking and Insurance companies, for example) an untested backup is not considered a good backup. And the only way to truly test a backup is install a fresh image of the entire OS (using checksums on the image too), so that you can read the data and make sure no clever ransome-ware software is secretly encrypting EVEN your backups.

oh, btw. "Blockchains solve this" haha.

So they are just at Phase 2 of developing prototypes with the Marine Corps Warfighting Laboratory? Ok, that explains why I've not heard/seen any deployment plans for these things within the next 5 years out here....which probably means if we do get them, we'll get them too late to influence the war with China over Taiwan.

Other comments are correct that the Corps isn't even close to solving the contested sustainment/logistics problems here in the First Island Chain, or in the South China Sea.

These seagliders are a nifty solution to the signature management issues, but their payload is tiny. We need the ability to move pallets of munitions or other cargo.

> And it would’ve sold like hot cakes.

I still don’t think it would have. It’s useless for anyone who’s pretending they might haul stuff. It’s worse than useless off road. And it’s too small to appeal to the dudes who buy dualies to take their kids to elementary school.

Your first sentence is 100% dead on, except that it also completely failed to solve any of the problems people actually have (or, at least, problems they think they have).

I'm aware of merchant transaction fees, but they're insufficient as an explanation. Just run the numbers. Say that a hypothetical consumer spends $10K/year. The person who carries that as a balance will pay $2700 at 27% interest, plus $300 from the 3% transaction fee, for a total of $3000, and they might get $200 as cashback. The person who doesn't carry a balance will pay $300 and get $200 as cashback. It's pretty doubtful that all the other services a credit card company provides - fraud detection, chargebacks, billing, recurring payments - cost < $100/year. Maybe if you never submit a chargeback and your card never gets stolen, but at best we're looking at them breaking even on their non-balance-carrying customers and making all their profits off the customers that carry a balance.

When you're providing a service to one group at or below cost and making all your profits off another group or another service, that's the definition of a cross-subsidy, even if you do get a token amount of revenue off the first group.

Why is it "Shared DNA" if all rappers do is sample and totally rip-off music (Logos, artist names etc) before them?

The concept of "DNA" with music goes much deeper than some lucky nobody who sampled someone's life work so they could pollute it with lowest common denominator poetry and a Roland Drum Machine.

I submit that oogling over people who steal music by sampling is not that deep, and there's deeper methods of musical analysis than "This band sampled this beat, this means they're a natural progression of art".

Every example I skimmed over was some hiphop artist who ripped off music before them.

Other artists have some shame and just copy chord progressions, but rappers went so far to just completely steal parts of the song.
