Very cool! Love the minimal design a lot, unsurprisingly.
My Minifeed [1] started with a similar goal of having a "HN for blogs", but then it grew to include search, related recommendations, custom feeds, lists, etc. I don't have categories though.
I've started putting together a curated directory of (subjectively) good YouTube channels and videos [1]. It's literally the 3rd day, so not many entries yet, but I plan to continue growing it like I did with Minifeed [2].
I worked at a quantum computing company that builds superconducting QC chips (so, not really applicable to one of the “bombshells” from the article). My team was designing the software stack which allows to control the QC, run quantum jobs/algorithms, and calibrate the parameters.
I’ve made two attempts to explain the work we’ve been doing and to explain the current realistic state of the industry:
The company I left a few months ago is planning its IPO this year. Like almost all other quantum companies, it’s gonna be a SPAC merger, not a pure IPO. Those traded companies mentioned in the other comments are mostly SPACs as well.
My mid-sized US city (Chattanooga) has recently announced a partnership with Vanderbilt and EPB (local govt-owned fiber ISP) which creates a Quantum Computing Research Facility [$,$$$,$$$,$$$] [1].
As locals are covering this news, I keep having this thought that nobody (perhaps less than a few?) even knows what those words mean (certainly not me). You speak confidently and clearly enough that I'm incline to believe it's kind of real.
So thanks for sharing your P[0]V with this dumbass (former data center) electrician (me). All the "Quantum"-phrasing represents to me is more local job opportunities.
>>@3m27s: "Quantum computing is basically trying to treat some isolated piece of the universe to behave slightly less randomly, for a very brief timeframe, so that it is useful to you when you try to solve some problem."
>>@20m: [simple flow-chart of interacting with Quantum Processing Unit]
>>@final.words: [paraphrasing] "Right now you buy a quantum computer simply to research quantum computers. Ours is $14MM"
The meme refers to the notion where an observation (i.e. interaction) collapses the wave function to a single value. As in, prior to observation, a system in a quantum superposition is said to be "in multiple states at the same time", and after the obsevation only one state exists, while all other possibilities are gone (or exist in other worlds, according to one of the interpretations of quantum mechanics [0]).
So, in that meme, the guy looks at one girl (the observed state) and "ignores" all other girls (all other possible states).
If they're going public I imagine they already sell some kind of QC chips. But, like, who buys them? Yesterday there was a new paper [1] that shows how Shor's algorithm could break realistic encryptions with as little as 10,000 qubits (instead of millions), but as far as I know quantum hardware is still orders of magnitude below even that target. So how big can the market actually be? Shipping to universities or other QC companies for playing around with some actual hardware is nice and all, but in the end someone will be left holding the bag. There is zero profit to be made at the end of the chain.
>There is zero profit to be made at the end of the chain.
Think of all the "sales" that comprise such things as space missions (ones without immediate real-world use) or large hadron collider. Or any other large, expensive, long scientific project. If you measure the outcome purely in money within decades, these things can be said to be zero or negative profit.
How much profit was at the end of the chain of the current Artemis lunar mission? Well, zero or negative, but lots of companies and people up the chain made meaningful progress and made a living. Quantum computing is just like that in my opinion.
The biggest problem in my eyes is the "game" of commercialization. This technology is in early research phase, but it's so expensive and not immediately game-changing that the public funding was never enough. So, companies started to play the "we sell products" and "we do IPO" games, which IMO doesn't make sense.
Profit is serves as a decentralized coordination for the allocation of scarce resources of the infinite number of commodities and combinatorics of products and services that exist in the world.
At this point my bet is that the breakthrough isn't going to be qbits per chip, it's going to be entanglements-per-second in quantum networking. If you could string together simpler processors in a cluster at anything approaching interesting scales then all of a sudden the orders of magnitude become a lot less constrained and it's just a money problem.
Quantum networking is a lesser problem than changing the state and keeping intact long enough. You can already move quantum state over fiber optics pretty reliably, so transport exists, but what then? You need to put the qubits of the connected chip into the corresponding state (which takes time), and do it many times, and all that time is an overhead.
Superconducting QCs are fast, but the state degrades incredibly quickly, so you only have a fraction of a second (maybe a millisecond at best, currently) until the entire state is garbage. Some other modalities like trapped ion are the opposite: state can live long, but each operation is orders of magnitude slower.
During my 3.7 years at the company, we had dozens of sales of full-stack quantum computers, chips + cryostat + control electronics + software, ranging from 5 to ~100 physical qubits. Naturally, the buyers are mostly research institutions and univercities who need a real quantum computer to do research on quantum computation and simulation (to a lesser degree with the superconducting technology, though).
(Often the research is done purely within clasically-simulated quantum computers, i.e. virtual QCs, but to verify and make the research publishable they need to run at least partial sub-problems on a real chip.)
Another, smaller, market is HPC centers. They buy and install quantum computers into existing HPC infrastructure because a) they have a few customers who need it (sometimes those same research institutions/universities), and b) they need to solve the integration problem for the future when QCs are actually used for real-world problems and big customers come to HPCs to run both classical and quantum high-performance jobs.
Here is an excerpt from my book I linked above, just to give a bit more context:
---
Since quantum computers are essentially analog devices that allow you to control, in a limited fashion, a set of quantum objects, you can do some research in foundational quantum physics. [...] Still, given the current state of the industry, classical computers outperform most quantum systems. But the research applied to smaller QCs can be scaled once the hardware scales.
Of course, the main area is quantum computing itself. From abstract, mathematical notions of algorithms to very low-level questions of calibration, many universities and research organizations are eager to have a quantum computer available to prove their theories and discover new properties. Commercial companies that deal with material science, battery technology, agriculture, and chemistry are buying quantum computers (or at least buying access to one) because they want to be ready if and when truly large-scale QCs become available. [...]
And finally, integration research. This is the least known and least discussed topic in the industry but is very important. Its significance is one of the motivations for writing this book. Quantum computers, being research tools, are not normal products. They are driven by software, like anything else, but this software changes rapidly and is rarely written with long-term evolution in mind. If you buy a quantum computer today, chances are your code will not work on any other quantum computer, or even on the next iteration of the same machine. At the same time, researchers often need to work with multiple types of machines simultaneously, and HPC (high-performance computing) centers, i.e. supercomputing data centers, want to integrate quantum computers into their existing infrastructure and provide a "quantum compute" service to their users.

On a similar note, I maintain and grow a manually curated collection of personal blogs with valid RSS feeds: https://minifeed.net/blogs
The criteria is simple: human-written (as much as I can validate myself), in English (for now), with valid RSS feed, and not a micro-blog (so, more than just feed of links or short tweet-like messages).
Similar to Kagi's Small Web viewer, or StumbleUpon-style viewer: you can get a random listing of blogs [1] or a random listing of posts from all blogs [2]. Feeds and posts are indexed, so full-text search works across all blogs. When possible and permitted by robots.txt, text is scraped for searching, so even if some text is omitted in the RSS feed by the author, search should work.
Though I do plan to implement a similar "view one random post at source" kind of view, soon.
UPD: Feel free to submit a blog, including your own! [3]
The implicit criteria (tech/business and adjacent) is an issue with all these lists for me. But it's also a personal list, which is great. I just wish literally anyone in these had a personal interest on anything else reflected in their lists because I keep checking them and being disappointed.
A topic that's come up before on here with others doing the complaining about a list I liked for this reason but wasn't top-loaded with tech: https://news.ycombinator.com/item?id=47015676
Here in Finland this would cost about 50 euro, which is still a lot, but for me the main reason to never go to a movie theater again is that even after paying all of this money, the first 15 minutes is filled with advertisement, then 15 more minutes of movie trailers, then some "IMAX" or whatever intro video. By the time the movie starts, I feel like I've been watching tiktok for a day.
Movie theaters around me (even the high end ones) have 30 minutes of commercials and previews before the movie, so I typically arrive 25 minutes after showtime, no problem.
However it is still frustrating that they expect you to tolerate 30 minutes of commercials after paying so much money.
The author uses Restic + Backblaze B2 storage. I was recently setting up backups for my homebase as well, and went with Restic + BorgBase [0]. Not affiliated, just wanted to share that I think they have a nice service with a straight-forward pricing model. They are the company behind excellent Pikapods [1], which may be interesting to the homelab crowd.
I also use backrest/restic on my NAS, but I went with a Hetzner StorageBox instead, a little cheaper for 1TB (I pay 5USD monthly including VAT, billed monthly too).
Me too, I highly recommend Hetzner Storage Box. It's cheap, and it works great (unlike their S3-compatible storage, which has been a huge fiasco since they launched it).
Could you elaborate on the issues with their S3 compatible storage? I've been considering it and haven't seen too many issues in my testing, beyond the lack of identity control.
I cannot say much about the quality, but I am also testing around with it at the moment. As for the identity control, you may be able to achieve this with a few extra steps, if you set up bucket policies for the credentials. For this, it would be a bit cleaner to move the storage box to a project of its own.
Most humans don’t, but maybe “most humans” do? As in, on average, as a collective, regressed to the mean of mediocrity and devoid of personality, we write like this? It’s not self-deprecating, it’s humbling.
There was an interesting case in Finland. Finnish customs used to apply a 22% tax (ELV) on top of the car tax for imported used cars from other EU countries. On top of that, Finnish law required VAT to be charged on the car tax itself.
There were multiple court cases and this practice was found unlawful (and actually against EU law). But the government did not issue automatic refunds, and instead requested that people "actively appeal" with some time limits. They also refused to pay interest on the money withheld.
AFAIK, only about 50M Euro was paid back. A lot of funds gathered between 2002–2005 was never returned.
I've been living in Finland for 10+ years, and this whole story was super surprising for me to learn because the prevailing notion among people here is that Finland is the land of law, and everything is done correctly and legally, always, and we can and should trust the authorities.
> There was an interesting case in Finland. Finnish customs used to apply a 22% tax (ELV) on top of the car tax for imported used cars from other EU countries. On top of that, Finnish law required VAT to be charged on the car tax itself.
There was no VAT payable on the car tax of imported cars, only the ELV (ei-arvonlisävero, literally "not value added tax").
The ELV idea was that for locally bought new cars you did have to pay VAT on car tax, but for used EU imports that was not legally possible (cannot charge VAT again when importing used item from another EU country), so an equivalent non-VAT tax was invented so the full tax (inc. VAT/ELV) stays the same.
But this was unfair for e.g. the reason that Finnish companies buying cars could deduct Finnish car tax VAT on local new cars on their VAT return but not the car tax ELV on imported used cars (since it was not VAT).

I'd pretty much grown up believing that that's how the US worked post-slavery (aside from occasional deviances from the rule). Since the start of the pandemic, I've had quite the awakening.
Hmm. The "active request" is quite common though. I agree that this is unfair, since it is theft, IMO, but Finland is not the only one forcing active engagement to get your money back. Even when the government stole that money from the people.
> we can and should trust the authorities.
Well, Finland has a fairly competent government usually for the most part. That mantra will not work in many other countries though - such as Germany. Just look at what Merz is doing; his left hand does not know what the right hand should do ...
That may have been the case for some time, but the current government in Finland is... well, perhaps I personally wouldn't describe them as fairly competent.
That's fair, and I understand these sentiments, but there is a pretty big difference between mistakes and deliberate illegal activity, or just not caring if something is illegal or not.
yeah that's the trade off of having a state. the alternative is getting mugged and having to pay ExxonMobil Police Task Force sponsored by Verizon to get your shit back (or deciding it's not worth the cash).
