The angle and cosine start to lose their geometric intuition when we go beyond 3D.

The concept of correlation has no issue with additional components. The concept of similarity of two 17-element vectors is clear. In fact correlation intuitively scales to "infinite component vectors": the dot product becomes multiplying two functions together and then taking an integral.

The Fourier transform of a periodic signal is based in the concept of how similar the signal is to a certain basis of sine/cosine quadratures spaced along a frequency spectrum. This is like a projection of a vector into a space; only the vector has an infinite number of components since it is an interval of a smooth function.
I used to hire cars fairly often so got used to all the modern conveniences. Now I don't do much mileage so bought a ten year old car and it is surprising how easy one can manage without all those expensive extras. My old car now still has lots of features I will never use.
Ask HN: Why not have “search” next to “submit” in this portal?
Now imagine if AMD could also use 5nm like Apple.

Chip shortage is hurting a lot.
The only missing part for me is thunderbolt. I'm so used to it in laptops I would have a hard time without it.
Building a no-compromises 'TRANSFORMER' PC
Yeah, but that is a small subset of distributed computing.

If you have multiple threads inside the same application talking to the same database, and modifying tables without proper SQL transaction blocks, anything goes and the borrow checker doesn't help one bit.

Additionally, if those multiple cores are being used by multiple processes, microservices style, there is also very little that it can help to fix IPC data races to shared OS resources.
Most of NFTs can be considered to have a centralized part, the `function tokenURI(uint256 _tokenId) external view returns (string)` function of the ERC721 interface provides a URI to the meta information associated with the NFT, many NFTs also implementing a `function setBaseUri(uint256 _tokenId, string memory _baseUri)` which can change the source where the meta information is pulled from.

Yes, DNS is centralized, the domains are kept by a centralized entity that obeys the contracts on top of which the platform runs. The created NFT is identifying the domain and the ownership of the domain, changing the nameservers of the domain must go through DNT and can only be done by the address that owns the NFT.

Right now it uses partners like name.com, godaddy etc to register the domain, the plan is for DNT to become a registrar itself and give more options to the user, eventually connecting the centralized DNS with a decentralized dns service.

The value added by NFT is the possibility of transferring the domain to another address without waiting the required 3 months that all registrars must obey before transferring the domain ownership.
Also the NFT can be auctioned, not being parked on sedo or other aftermarket, but pointing to users nameservers while it is being auctioned.

There is no rule that blockchain should be used only by fully decentralized services, centralized businesses can adopt the technology too.
For now the only production-ready backend is the historical LLVM backends.
Channel of Robert Ghrist is very overlooked one: https://www.youtube.com/c/ProfGhristMath. He does whole courses with awesome animations. He also has single variable calculus course on Coursera: https://www.coursera.org/learn/discrete-calculus.
Others have discussed a therapist, and while they do have professional training, one of their biggest values is talking to someone not in your social circle.

It allows you to dump emotion and mental stress, without worry of peer group judgement.

I think it's a good idea to share with spouses, but, also good to not dump on them. And each situation is unique. So if you do don't want to, don't.

People used to dump on their priest, or their bartender. The therapist is sort of a replacement here.

Last thing... regular talks with that outlet, does more than the talk overall. You've let stuff bottle up.

Letting it out regularly helps.
Same with human memory recall, and that is used in trials as evidence

Slovenia planning to tax crypto to FIAT conversion with flat 10% tax
For reference, until quite recently, chips that were referred to as being "14nm node" were actually built using light that was 193nm and lots of special techniques like multipatterning, immersion, crazy lenses, etc. So when EUV arrived and is now using 13nm, you can bet that 13nm will allow quite a bit of runway for creating tiny features -- one concern I'm sure is the use presently of mirrors for all of the optics, so not sure how that would work for something equivalent to immersion -- seems like not possible maybe?
What a bs fanboy article.. the author is going gaga over something that isnt even out in silicon yet, and has no credible plans of software ecosystem coming on top the hw( if it materializes). Unbelievable hype.
Everyone is saying to see a therapist, but what is really important is that if you don’t feel comfortable with one, you see another one until you find one that you are comfortable with.
There are several good recommendations, I think Michael Penn's channel is really nice, I enjoy the no nonsense blackboard approach to math.
(2017). Repo hasn't been updated since 2018.
You are using logic.

That's not how corporations work.

I work remotely for large corporation (over 100k employees) and it wastes on average an hour of my productivity every day on stupid stuff. For example my office PC becomes unavailable every time it gets an update, at least once a week. They force restart during working hours. If there is somebody in the office I can call them to reboot it, if not I have to drive there. Everybody has the same problem. Meetings are disrupted, plans are thrown in disarray, people are loosing sometimes entire day of work.

The problem has been known before covid and has not been solved.

Any normal logical person would throw resources into solving the problem, but the people responsible just say they are busy and why is that a big problem if you can just press reboot?
this must be a bot, right?

The acquisition of the domain is done by the business behind the platform and provides a bridge from the NFT to the domain.
Once the domain is acquired by the platform and the NFT is claimed by the user, all nameservers and domain registrant contact information can be changed with the NFT owner address signature, the backend of the service taking care of the updates on the domain side.
While I totally agree with your post (especially the point that a course where you implement your own OS for real hardware is great), I would like to add that USB is a massive foundation/abstraction layer. Once you got USB going for HID, you are much closer to USB for storage, USB for networking, etc. So it certainly is troublesome from an educational perspective but the complexity is where it belongs.
Just a caveat: Wildberger subscribes to a strict, non-mainstream view that rejects the existence of infinite objects. His exposition is fantastic, and as you say the content is definitely thought provoking if you have enough mathematical sophistication to (at least superficially) understand what he's about, but I wouldn't recommend it to anybody who hasn't taken a traditional real analysis course.
Docker no longer free for large businesses
Personally, I wouldn't put ASML in the buy bucket for very long though. The stock has already more than tripled during the last year, mostly off the back of the big producers announcing enormous expansions of production capacity which is great for ASML. This Industry is cyclical though so in a couple of years once those factories are opened, there will be a large overcapacity leading to scaling down capex.
Everything that's used should be cached in RAM, anyway. Everything that isn't used, well, I prefer that not to be in RAM. These things don't exactly have gobs of it.

And why would I want to remove the SD card after boot? Now I can't reboot the system, and it won't reboot if it crashes?
You should talk to your wife about all of this, I'm sure she would want to know and would want to help.
> dot product of two vectors is just cosine of the angle between them, multiplied by their lengths

How do you define the "angle" between two n-dimensional vectors? Most likely using the dot-product and the arccos. "cos(angle) times lengths" might give a good intuition for 2D or 3D space, but it doesn't help in higher-dimensional vectors.
> The SET and WHERE clauses in ON CONFLICT DO UPDATE have access to the existing row using the table's name (or an alias), and to rows proposed for insertion using the special excluded table.

Therefore you can do DO UPDATE SET table_name.column = Excluded.column WHERE table_name.column IS DISTINCT FROM Excluded.column RETURNING *
I expect a lot of the oppositional behaviour re: covid we’ve recently witnessed, have their roots in a need to assert an illusion of control, in much the same way toddlers assert control by refusing food or holding their bodily functions.
MacOS mostly leaves me alone. It works as it should and never bothers me. It's simple and reliable and I never give it attention.

My experience with desktop Linux is that it's always on your mind, like an old motorcycle. You're always fiddling with something, listening for noises, keeping a mental model of its internals in your mind. Keeping it running involves knowing how a carburetor works, and having a few motorcycle forums on quick dial. You want to believe that it's better than an overengineered modern car, but you're always fiddling with it at red lights.

It's fun to mess with old motorcycles, but only when your goal is to mess with old motorcycles. Sometimes you want to Just Drive. That's why they're rarely your daily driver.

MacOS is the trusty sedan I need. Linux is the contraption I take out on the weekends.
I am real unfortunately.. this started when I was about idk 15 this lady came into our life
Same here, been using the g14 since last year as my main arch machine and couldn't be happier.
This is the best advice you'll get on this subject. Therapists can help you with your problems far better than we ever could. They can determine if you need medication to help you get through this rough patch and what sort of therapy you need. You seem to have funds to do this as well, so consider it an investment in your mental health.
I don't think there's going to be a consumer application of this anytime soon. However this seems practical enough for big organizations to break things like TPM, clone credit/debit/SIM/NFC cards and do cybersecurity research.
Top IT Companies in India
Split keyboards have been around for quite a while. You can even see the Kinesis Advantage keyboard featured in films like Flubber and Men in Black and plenty of companies have made ergonomic keyboards.

I think there's a sort of hobbyist renaissance going on right now, though. Plenty of new keyboards are being designed and built because it's more accessible than ever to design your own pcb or if not that to get someone else's design printed, which along with the general mechanical keyboard enthusiast market, has given people a wealth of options to choose from.
Eww. I get the rationale, but Python's packaging/import logic is already ridiculously convoluted. The underlying problem is using global mutable state (e.g. /usr/lib/.../site-packages). Giving each application its own package directory is better; there are Python-specific solutions to that (like virtualenv mentioned in the article), but I prefer Nix since it's language-agnostic (it can handle non-Python dependencies too).

I'm also not a fan of all the Rube Goldberg machines being cobbled together to appease Docker's fundamentally broken way of working:

> Distros that produce official images for single-application containers (e.g., Docker container images) should remove the EXTERNALLY‑MANAGED file, preferably in a way that makes it not come back if a user of that image installs package updates inside their image (think RUN apt‑get dist‑upgrade). On dpkg-based systems, using dpkg‑divert ‑‑local to persistently rename the file would work. On other systems, there may need to be some configuration flag available to a post-install script to re-remove the EXTERNALLY‑MANAGED file.

Here a "single-application container" is assumed to contain an entire OS rather than, you know, a single application. That was supposed to make dependency management easier, since we can tailor the OS to just that one application; but based on this article it sounds like even that was a lie. Should we revisit the assumption that Docker makes dependency management easier? No, the OS maintainers are now expected to change their distros, to add another layer to the Rube Goldberg machine.

I also find it pretty alarming that 'apt-get dist-upgrade' is given as an example of something we might want to do to an "official image". What's the point sanctioning a snapshot as "official" if we're just going to immediately, and non-determinisitcally, overwrite arbitrary parts of it based on external-server-state du jour?
Opinion about who is an undue burden to society tend to diverge.

Your personal problems of being fed up cannot be solved with public health policy.
The very last example in 2.1 ("__bar.foo { color: red; }") should instead be "foo.__bar { color: red; }" if I understand it correctly.
Only if you believe in the efficient market hypothesis
Service providers you depend on will fail, either in catastrophic ways or weird almost-working/most-of-time ways, so emergency incidents are going to happen. It is just a matter of time and scale.

Another thing to consider is that your customer might incorrectly point fingers at you when in reality the problem is at their end. This might be due to incompetence or internal politics. And sometimes the blame is more fuzzy when they increase load on your service many-fold one day and latency spikes, which has knock-on effects on their end.

Whatever the cause you might need to spend a lot of time to carefully debug and educate people at your customer to keep that organisation happy with your SaaS.

A response time of 30 min 24/7 is going to ruin your life, so charge what you consider an obscene amount for this and plan to hire help to cover it.

Consider suggesting a very lax but cheaper SLA to them, they might not care much, maybe it is just a check-box on their end?
Thank you! I just love my family but as told my wife this shit is something I am not ok with.. and we want to have kids but I do no really want them to be involved if that makes sense..
Yes. But not for that reason. You decided to work for Amazon. That's why you're stupid. Better to be homeless.
No, I am not (that was also not my point basically). My point is that you are going to pay for a) something you got for free (as in beer) before and b) something you don‘t (maybe) need/want.

I think it is a very valid question how to monetize Docker (and all the other libraries we are using for free), but I am personally not sure that subscriptions to everything are the solution.

I am sure that this expense should not get into your way if you have 50+ engineers, however if you think that with all expenses…
In addition to all the great advice on this thread, how many hours a week are you working? If you can try to cut back down to 40 for a while.

What do you do for fun? If you're in a strong burnout it might be hard to answer. If you can get to make it your hobby to find something fun to do or reconnect with something fun you used to do.

Video games, hiking, writing, painting, drawing, playing an instrument, going out for a coffee or having a video call to an old friend can really help.

It's been written elsewhere but find a therapist and take care of yourself. Try to do 15 minutes of intensive cardio or 30 minutes moderate. Eat a good meal.
I think the "speaker's proposed alternative" is to do more academic research in this area.

You have good questions in your comment, and I think he is calling out for searching answers to them and other similar questions. Apparently, the operating system researchers haven't been doing this enough, or at all. His speech is a lament for this state of affairs, and a call to get excited about finding out what benefits would be gained by doing things (very) differently.

But that's just my take, and I'm not working on operating systems research.
Yes it does. The AGPL is based on the same free software definition that's stood for many decades, so where do you get the notion that the shift from personal to cloud computing means we should change or replace the free software definition.
Thank you. Thankfully the wife and are very open and talk about this stuff. She thinks it super weird and not cool.. which means idk what to do.
For what it's worth, IntelliJ CE has a lot fewer restrictions than LispWorks PE.

This is fine for a software evaluation period / demo, but it's not at all equivalent to the IntelliJ free offerings:

> There is a heap size limit which, if exceeded, causes the image to exit. A warning is provided when the limit is approached.

> There is a time limit of 5 hours for each session, after which LispWorks Personal exits, possibly without saving your work or performing cleanups such as removing temporary files. You are warned after 4 hours of use.

> The functions save-image, deliver, and load-all-patches are not available.

> Initialization files are not loaded.

On the other hand, I do wish more "expensive" software came with a demo mode like this (e.g. Mathematica).
Impressive results.

Can anyone think of negative consequences for end-users? I imagine this is not really a practical attack vector on your YubiKey's 2FA keys or TPM disk encryption keys.

All the applications I can think of are unwanted just for DRM and other compute-freedom restrictions, which I see as a win. (See sibling comment from no_time).

Maybe one edge case would be things like SGX? IIUC being able to extract the secret keys would allow one to write an emulator that can run arbitrary code and pass remote attestation, while still being able to inspect (and modify) the code and data. This is something which feels at least somewhat useful and not fundamentally user-hostile. But my understanding is that the security model there might be broken regardless.

Nice, this seems like a neat solution for our needs, thanks.
Gonna take a peak, thanks
Infinite? Not at all, we’re talking about identifying absolute frequencies here, not just telling them apart. For sound I’d say it’s less than five, for colour perhaps a dozen.
The point is, it's helpful if the reader can evaluate just how faithful the transformation is vis-a-vis the original.
I personally think that a lot of these convenience features make for worse drivers. Blind spot assist means that people don't physically check their blind spots, reversing cameras make people rely on the screen half way down the dash instead of turning their head to check their surroundings, etc etc. I do find them nice as well, but overall I've noticed drivers getting worse for having them.
This laptop is clearly not designed for battery life though. The battery is tiny inside.
Yuzu Progress Report July 2021
I once got told my my manager to reduce the cost of my email inbox on the server and download it to my local machine.

This was email provided and owned by the very company I worked for, and it was costing enough for management to care.

Maybe enterprises have changed since then, but I wouldn’t be surprised if stuff like this does start asking questions as it’s a new cost on a budget.
> I know what that sounds like in my head

as in you can replay the tune as a, well, tune?

For me, the "music" in my head is just my voice approximating it.
Live for yourself and the people you love, few things matter outside of this.

Ditch things which may seem important or interesting but which in the long run are unlikely to have a significant impact on your life (e.g. reading Hacker News daily, watching the news, watching TV)

Your wife is married to you, part of the bargain is sharing both the good and the bad. I don't know what the financial split between you and your wife is, but even if it is 50-50 tell your wife you are having a rough time. Try and work out a system where she carries more of the load while you figure things out.

Seek professional help, or engage in meditation.

I wish you the best of luck.
What strikes me is that the jaguar (?) got "kind" eyes with SR3, and "mean" eyes with the other algoritms, including the original!

Oh, oh the ragnarok of systems programming, moores plateau stretches on, parallel is coming to a limit and now its goodbye abstractions & no-skill-lib-glue-code, hello 80s hardware hacks and efficient programming again? Will OSes be produced like games, were they start with a "reuseable" oo-engine and then that is broken down into data-orientated design.

I thought we had more time..

Cant we global warm postpone this?

Let the next generation sort it all out?
Sad that nobody has commented offering help. Very typical of this site.

Take a breath, friend. It sounds like you have many good things and many bad things in your life.

The first step is to let go. You have a brain that likes to think about things-- try to give your brain a vacation.

I noticed my life got a lot better when I decided I was just going to stop caring and stop thinking about some things.

For the things that really plague you, talk to a trusted friend or therapist. But, most of these thoughts won't plague you anymore if you find a guilty pleasure with which to occupy yourself for some time, be it food or sports or games or whatever.

Everyone has some little escape from the bad parts of life, find yours and just don't go overboard :)
I'm not saying the employer should subsidize it. Some employers might. If your employer provides that perk, it might make sense to use it. Similar to how if a restaurant provides free wifi it might make sense to use it.

I think the real way to be secure from MITMs is to use a device that you control the root CAs of. If you control the root CAs, you'll be safe no matter what network you're on. If you don't control the root CAs, you'll be vulnerable no matter what network you're on (but some networks will carry a higher likelihood of an attack).
I've heard of ASML for over a decade now - Dutch mainstream press might ignore them, but specialized sites like tweakers.net and partners (it's been one of my daily visits for nearly 20 years) have reported on them for ages (https://tweakers.net/zoeken/?keyword=asml#filter:q1bKTq0szy9...)

As for the stonks, it looks really healthy, only ever having gone up over the past 20 years. Significantly in the last two years though. But I think it's a safe bet given there's little competition on the market at their level. I'm sure e.g. China is working on a competitor, but they have their work cut out for them - even if they have the designs for these machines.
