From EEG analysis people have characterized beta, alpha, and theta states.

People tend to generate beta waves when their eyes are open, alpha waves become more prevalent when you close your eyes, theta waves are associated with a dreamy kind of state.

First go into an alpha state by some meditation like

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

but skip the "forehead is cool" part because it makes you more alert.

To go to a theta state it helps to visualize a lot of motion in different directions. You might imagine going down in an elevator, then getting out and going down a hallway, opening a door, going down another hallway, climbing up a ladder, opening a hatch and getting outside, running down a path, suddenly popping up into the air and flying, catching a ride on an airplane, jumping off, etc.

After a fair amount of that kind of imagined movement you may be feeling rather dreamy and ready to drift off to sleep.

So far as pharmacology I've found that if I take any *-prazole drug for heartburn I cannot sleep a wink all night. I had a phase when Trazodone was helpful but later I couldn't tolerate it. I've found Gabapentin is useful but you might have a hard time getting a script for it because off-label use of that drug is perceived to be a problem.

I am not a web developer. I would love to have a GPU that allowed me to compile my code faster, but, so far, it's not the case. I don't do 3D visualization or games either, so, for me, the tiny, cheap, and very compatible iGPUs work just fine.

Ask HN: What is the Hacker News database structure? Does it use tables or NoSQL?
HN always seems pretty fast and is probably well designed from a data structure standpoint.

It seems that each comment and submissions are assigned a monotonically increasing number; do both submissions and comments share the same numeric space?

How is the content hierarchy stored? Is it a single large table with (for example) a structure that looks like id, parentID, contenttype, content?

Is data stored in an OLAP SQL database, on disk as flat files, in DBM files, etc?

What kind of performance is required? Is the database distributed across more than one machine?
What to do with a problem like Wikipedia. It’s ultimately a fantastic source of information like nothing else on the internet. That has to be worth something right?

Problem is that people probably don’t bother to donate as much as they could or should. I know I haven’t donated.

Is there another way it could be monetised without ads?
It shouldn't be sorted by rating to begin with.

If I search for "doughnuts", it's rather unlikely that I'm interested in "Chapssal doughnuts" (top spot), "Pumpkin Doughnuts" (second spot) or even "Gluten-Free Baked Chocolate Doughnuts Recipe" (third spot).

The list should be ordered (somehow, no idea how) by classic or common interpretation of the query first and pushing exotics, varieties and fusion stuff down to the very bottom.

Another one is "sourdough" - "Caesar Salad with Sourdough Croutons" is the top suggestion, followed by "Hard-Boiled Eggs and Parmesan on Toasted Sourdough" and "Radicchio Salad with Sourdough Dressing". Not exactly relevant.
As suspicious as I am of their intentions, I also would like a world where small businesses do not need to hire lawyers. As in, I think privacy regulations and other regulations are best if the amount of work requires is proportional to your market capitalization. Of course, with lobbying things end up going in the exact opposite direction usually.
Not really though.

Long term, sure, but this isn't a long term situation. Can't move overseas before the harvest.

Besides, what kind of company looks at the supply chain situation right now and says "yea, now is a good time to move all of our business-critical infrastructure overseas."

And all that sets aside operational & regulatory challenges moving heavy manufacturing overseas.

It's pretty safe to assume that, after 30+ years of offshoring, old companies who haven't yet offshored have good reason not to do so.

We observe the past all the time. It's most noticeable in astronomy, but since the speed of light is finite, it's impossible to observe the present. Ever. Any observation is based on light (or something slower) travelling to you.

For now, we are focusing on rolling Grafana OnCall in the Grafana Cloud. It's a very common use case to have such a system outside of your infrastructure so it won't be affected by probable issues. It should be alive even when everything goes wrong.

I am genuinely curious how a ZFS "special" device[1] which absorbs all metadata for a pool would help this kind of a workload.

The "special" device is a full-blown vdev that you add to a pool (it is not a cache) - typically a 3 or 4-way mirror of SSDs.

Now all metadata read and write happen at SSD speeds.

We wrote about this in the rsync.net Technical Notes for Q3 of this year[2].

I know what this kind of SSD based vdev does to typical mixed file performance but I'm not sure how metadata-heavy a postgres implementation is ...

[1] Yes, they really are called that.

Show HN: You.com, private search engine that summarizes the web – built for devs
Hello All,

My name is Richard Socher, and I'm the founder of you.com, the world's first open search engine platform that summarizes the web for you. We launched our public beta today, and are excited to share it with you.

If you're a developer, we have several "search-apps" such as StackOverflow (with code snippets), W3Schools, MDN, Copilot-like Code Completion, json checkers, and more. All of them geared to help you code faster. Let us know if you have other app ideas for how to make your coding life better.

We believe in superior privacy choices without losing convenience. Our private mode is the most private experience - we don't store your queries or track your clicks or share IP, etc. And even in our personalized experience, we'll never sell your data or follow you around the web and we'll never offer privacy-invading targeted ads.

We wanted to create a search engine that delivers relevant content, not ads or SEO'd pages, and do it in a whole new interface that puts you in control through personalized preferences. We hope you'll be able to search less and do more.

Looking forward to your feedback and will be here to answer any questions.

Thanks!

It's somewhat amusing to see someone write a lengthy rant against testing because memorizing information is archaic, when the ability to write, at least at the start, is learned this way.

The most obvious example why you're wrong is learning a second language. Even learning a language outside of a classroom generally requires memorization of fundamental vocabulary (and sometimes a writing system); it therefore makes sense that a class teaching a second language would test students on this memorization.

Now, other fields might not be so obvious, but they require many things to be quickly accessible, much in the same way that one might need quick access to a word or a character with a second language. A biologist needs to know and understand the central dogma, an engineer needs to understand mechanical stress, and a chemist needs to be able to read a structural formula; they need to be able to do these things essentially instantly (and understand them intuitively) to be able to even discuss more complex topics, because complex information builds on simple information. Hence it makes sense to make sure those pieces of information are understood and readily available before sending a student off to a more advanced topic.
Amphetamines Used by a Physician to Lift Moods of Famous Patients (1972)
As someone from a second-tier Canadian city that had relatively few tech employers, this has definitely been a boon. Previously there was one game in town, and they attracted talent with a fancy office and above-market salaries for the region. I left after a couple years and joined a bay area startup remotely for a ~30% pay raise, and several of my former coworkers have as well. The company in question is suffering from a brain drain as old-time employees leave for greener pastures, and they struggle to attract international talent - because they didn't have much cross-polination with other tech companies in the past, there's a ton of NIH built by very smart new grads with no real world experience, and experienced engineers tend to take off once they realize the extent of the problems.
Something to note is that the US culture in general seems to value technical expertise higher than some other cultures. For example, it's been a common experience for me to have Doctors and Dentists quiz me about my work and make statements that they wish they could have followed a similar career path. I doubt that would ever happen in England.
20-year career so far. Never seen a database swapped out. I've seen "apps" replaced on top of databases, or more programs added to access the same database. I've seen the app and database both get thrown out and replaced, because they were tightly coupled[0], as the parent advocates (Rails + ActiveRecord seems to be prime for this kind of "gotta throw it all out" situation). I've never seen the program stay the same while the DB is swapped out from under it.

[0] yes, that's actually tightly coupling them, because now your DB is too unsafe to use without the "app" you built on top, and doesn't provide enough functionality to make it worth trying to retrofit that safety onto it.
Wikipedia Founder Larry Sanger: "Wikipedia Is Badly Biased" (https://larrysanger.org/2020/05/wikipedia-is-badly-biased/)

Such a shame.
it is well-known in USA non-profits that some fundraising in some orgs takes over, and that those who can "make rain" get long-term status. Counter-point? lots of countries do not have "non-profit" at all.

Wikipedia is a precious, troubled project IMHO
Their jurisdiction does, though.
"Imagine being in Minecraft, then walking your avatar through a portal that takes you into Roblox. Or more likely just hitting a button and being there."

Microsoft has actually been experimenting with this technology for a while - their implementation is quite sophisticated, and it's shipping in Windows now. You can actually try it out today: open Minecraft, then press the World Switcher hotkey combination (press the Tab key while holding Alt), press the Windows key, type "Roblox", and press Enter. If done correctly, your avatar will now be in Roblox!

It's pretty groundbreaking stuff, to be honest. Under the hood, the old universe is dynamically unloaded (possibly swapped out to disk) while the new one loads in. And, even better, if you press the World Switcher hotkeys again, you'll be right back in Minecraft - exactly where you left off.

...

Of course, I'm sure you meant that you'd somehow share information between Minecraft and Roblox- I'm sure you'd agree that arbitrary in-game items are unlikely to be transferable, but at least avatar appearance, surely? Well, hmmm, that'd make both games look worse, with awful art-style clash. Well, I guess you could store a few parameters and transfer those, and let each game interpret them to render an avatar that fits in the game's style?

... Ah, I've just made Miis again.

Okay, well, hm, if transferring avatar appearance isn't especially interesting, what about stuff that doesn't directly correlate to anything in-game? For example, the social graph, friends list, communications. Imagine being able to see what worlds your friends are in, talk to them while in your current one, and join their worlds with just a cli-

... oh, that's just Steam and Discord.

So... what's new, here?
> why are Republicans proposing big new regulation that would apply to every US business, impose additional bookkeeping & accounting work for every business, and then not improve consumer privacy protection?

The answer is obvious with their historic agenda...

> discriminate against or make an economic opportunity unavailable on the basis of race, color, religion, national origin, sex, age, political ideology, or disability of a persons or class of persons.

They want, ironically, the anti-discrimination clauses. They want to prevent someone from discriminating in tech. That would (they hope) block the perceived anti-right bias, and maybe even prevent companies from blocking people like trump all together.
Wikipedia is far and away the most valuable project the world has ever seen and this guy is complaining about donation emails?

> For example, do you feel it's appropriate to blame race

Where did I "blame" race? And for what?

People who are white have done horrible things in Africa. People who are black have done horrible things in Africa. It is, however, a simple fact that the people who are white came to Africa from other places.

Looking at the history, I don't think it's difficult to make a strong argument that, on the whole, the arrival of white Europeans on the continent has hurt the (black) people who were already there more than it has helped them.

That's not blaming white people for all that ails Africa. It's also not disingenuously dismissing the malign influence white Europeans have had on the continent.

Again, let's look at the statement the OP took issue with and suggested was racist:

> Men like Denard but perhaps a little less theatrical—many of them South Africans—took the next logical step. They founded businesses with boring-sounding names but a deadly purpose: to fight Africa’s nastiest conflicts on behalf of corrupt, inept governments, and for profit

Where's the racism in this? Is this not true?

I've heard people say this since the program is so large, but the same could be said for any large research university that has a CS master's program.

Anecdotally, I got my master's degree in CS at USC and had a good experience overall. I definitely learned a lot and was able to fill in some gaps in my knowledge of CS theory and machine learning. I was also able to get offers from Google and Facebook from their on-campus recruiting programs, and I know several other people in my cohort that did the same.
I don't know what colleges you're looking at, but you're misguided if you think colleges spend 100% of the tuition they receive. Schools like Harvard, Yale, Duke, etc. have multi-billion dollar endowments that just keep growing. Many colleges have so much money coming in and are forced to spend to keep their non-profit status that they build opulent dorm rooms, buildings they don't need, and have more Vice Provosts than banks have Vice Presidents. My own alma mater has TWO art museums on campus!
You don't have to do everything in house, you can for example buy servers with a on site support agreement. Then you just have to buy new servers at regular intervals, you don't need to have a guy that can fix a server with a soldering pen.

Same for internet connection, you can buy transit, no need to become your own ISP. So you don't need people who deal with peering agreements, etc.

For electricity you can make a support deal with a local electrician company. You don't need a guy who can build and maintain a custom power supply unit.

It does help however to have someone with basic sysadmin and network skills. But if you don't have that, you will sooner or later screw up your AWS infrastructure too.
It's qualitatively different, but there's some similarities in appearances. The end-user viewpoint, if this trend grows, is that the majority of the internet could present as a set of subscription packages -- the more you buy, the more of the internet you can access, and at higher service levels. Because of these new financial incentives, previously open, ad-supported websites will shift to becoming closed, subscription services: as the friction for end-users to subscribe to things goes down (because of federation*), this becomes more common. The open web goes dark. Conversely, since this is also an income source for the platforms/referrers, they'll want to boost referrals to partnering companies higher than non-partners -- tiered service. It's true this isn't the hard severity of an ISP throttling, or cutting off, non-partnering websites; but it's a soft analogue of it.

*(This friction can be zero. You needn't take any positive action to subscribe to the Nth website; rather the platforms you subscribe to abstract that away for you, as they monitor all your clicks and visits, and handle the income-splitting transparently behind the curtains. Basically the Spotify model, for the open WWW).
To be fair, this is one of the few non-profits that benefits most people and that is actually used day-to-day by the majority of people with an internet connection.

Honestly my biggest problem is that neurotypical people are generally caught off guard and dont understand my impulsiveness/risk taking/flippance with major life happenings. i.e. quitting my job on a whim. My risk taking behavior has turned out well for me, but makes me feel like a pariah among conservative/responsible friend groups. How to handle it? Find people that understand and are okay with people who act outside the bounds of "what is okay". Aside from that, I use gating behavior where I keep distractions far away, alcohol, parting, distractions, for periods of time (1 - 3 months), and then allow myself to be erratic and risk taking for a few weeks.
If you didn't want something like this to exist, maybe a good way to get it to be un-enjoyable by the people who want to use it would be to show up and yell intolerable things at the top of your lungs. You can already see many instances in this thread of people assuming that sites like this exist solely for the pleasure of racists, which makes "normal" people think it's not for them. Mission accomplished, all the normies will stick to their "mainstream" sites where content is moderated and they don't have to worry about parsing what is "right" or "wrong" because someone in Mountain View wrote an algorithm that surfaces wrong-think to a minimum wage disposable worker who decides that yes it is wrong-think, and removes it.

Think about this. Last year, if you said that covid might have come from a lab, you were saying something that was obviously wrong, your post should be removed, you should be suspended, and you might be a racist as well. Fast-forward to now, well actually it's pretty possible that it might have come from a lab, maybe we should have talked about that...

The problem to solve with anonymous message boards is getting rid of the bad-faith actors. I think we need a system that allows individuals to subscribe to independent moderators. The central company provides the infrastructure and makes a marketplace where individuals can upload their own ban lists and moderation algorithms that people can subscribe to, allowing you to curate your feed based on many options of moderation. Maybe kinda similar to ad-blockers, some of which get rid of everything and some of which allow some stuff through, that follows standards.
This way the central company is insulated from having to worry about moderation, except to remove obviously illegal content, and individuals get a variety of choices and can't blame some central authority for making decisions on the content they see.
They also generally have 7 times the vattey capacity and at least 15 times the power output. The speed limiter is not the main difference.

"Bezos lives largely tax free, even though he's one of the richest men in the history of the world"

It's a ridiculous assertion. Easy to check that this is not true.

Jeff Bezos sold $10's of billions of Amazon stock in 2020 and 2021.[1] Of COURSE he paid taxes on that.

So he's personally paid billions in taxes in a single year. This makes this story based on something that is not true.

You'd think the CBC would do fact checking.
