The neutrons in a DT reactor have to be used to breed more tritium, by absorption in 6Li. One cannot afford to lose many; indeed, some neutron multiplication by (n,2n) reactions on various structural materials would be needed to make the cycle close.
Like the old discussion about freedom of speech.

That the robber baron who owns the papers can say what he wants doesn't mean much to the man who is a black list for the rest of his life.

Freedom of speech is not freedom of consequences indeed.
Indeed, I was unclear. But the features are tied at the hip. SNI exists because TLS needs a way to discriminate separate certificates for the benefit of requests on the same port using distinct HTTP/1.1 Host headers. In my experience it's absolutely routine to talk about them using the same terminology.
Too bad he didn't try other protocols. I wouldn't be surprised if DNS or ICMP tunnel worked too.

MIT's design also uses 40% of the world's annual mine production of beryllium, for a single reactor. Using the entire estimated Be resource in these reactors would supply maybe 1% of the world's primary energy demand.

I think this was the case before. Nowadays it's a different, worse situation. We have more means of knowing but people a proactively smearing information. It's a super impressive neurotic trend of "modern" societies.

Show HN: A thin Python library to access HN data using Algolia's API
Hello community. Some time ago I was trying to create a project for my students using Hacker News data. As you might know, HN offers an official API [0], but it's based on Firebase and I felt it's main usage is to build clients, rather than consult data.

I found out that Algolia also provides an official REST API [1]. It's exactly what I needed: the ability to "search" HN. Either by keywords, type of stories (Show HN, Ask HN, etc) and/or date.

So I created a thin python wrapper on top of Algolia's Search API: https://github.com/santiagobasulto/python-hacker-news

The library is in early stage, but already usable. A few examples:

How to search posts from one user:

results = search_by_date(
author='pg',
hits_per_page=1000)

How to search posts by type (this would find this same post)

results = search_by_date(
'thin python library',
show_hn=True,
hits_per_page=1000)

I'm working on implementing the the other methods. If you have suggestions please bring them up!

> It depends on the kind of rent control. Housing has important asymmetries it's reasonable to address through legislation. One is asymmetry in scale: you have one unit; landlords have many more.

Not necessarily true. Sure , the landlord knows more about the apartment but you know more about yourself as a tenant. Landlord takes a huge risk in terms of allowing someone rent, especially given protections afforded to that individual. Most experienced landlord will cite tenant selection as very important and a huge risk. One tenant that refuses to pay rent or damages property can wipe out the return of 9 other units.

> This gives them stronger negotiating power.

I have more options as to where to move. The landlord owns a very expensive illiquid property. He can't just sell it tomorrow but I could easily choose another rental.

> Another is cost of change. It's much more expensive for me in time and money to move than it is for a landlord turn over a new unit.

Its very expensive to fill a rental. A landlord usually needs at least a month to find another tenant. That's a month of foregone rent

> That means a landlord can extract money well above a true market rate.

Market rate is the rate the landlord can get. If a transaction happens at that rate, that's the market rate.

> A third is of interest. Individuals and the community have a interest in healthy social bonds, while absentee lords mainly want to extract cash.

Not sure what "absentee lords mainly want to extract cash" means. Yes, most landlords manage properties as an investment. Landlords also have an interest in the community as they own equity in that community that would appreciate if the neighborhood gets nicer. I don't see your point.
Leaders do not operate in an environment where they can tell the truth and do things based on facts on the ground.[1]

Leaders have one real job, that is to reward (through jobs/money/political clout) people who help them. If they don't think telling the truth about deforestation or global warming will help their sycophants, they will tell lies.

The neutron flux inside a fusion reactor is many orders of magnitude higher than the maximum allowable for human exposure. The flux is low on the outside precisely because of the many absorption lengths of shielding between the reactor and people.
> I wonder how many rent-controlled residents in SF/NYC would accept a $100k buyout that would convert the apt to market rate.

NYC has a possibility for something like this, but only in the context of condo conversion. Although there's always stories floating around about people that didn't take it and are living for $250/mo in some fancy condo building my sense is that generally an arrangement is reached.

A 1995 laptop would have been incredible sci-fi future-tech in 1975. A 2015 laptop, on the other hand, is bascially just a thinner, faster, lighter version of the 1995 one. It doesn't even do much more - surf the internet, write documents, play games. If you're patient and determined, a late 90s machine could even service you today.

There's definitely a sense in which the 90s marks the beginning of the era of the recognizably "modern" computer. The oldest computer you can run Linux on will be from the 90s. GUIs settled in the 90s - you can make a modern machine look like Windows 95 with nothing more than a desktop theme.

Maybe "matured" is a better word than "stagnated".
The focus on ignition is strange. If the engineering and economics look hopeless, then why focus on ignition?

Of course people were reporting about it before Bolsonaro got elected. We are talking about a politician that had campaign promises thar openly attacking the environment! And one who is on a personal vendetta against the environment police, as evidenced by that time when he was caught ilegally fishing in a nature reserve.

He was seriously considering to extinguish the Ministry of the Environment, and merge it under the Ministry of Agriculture. In the end he did not because of the public backlash, and settled by only nomeating an environment minister that is fully subservient to agrobusiness...

The Bolsonaro administration is short sighted and paranoid of "leftists". Four of the areas that are suffering particularly bad because of this are the environment, education, foreign policy, and human rights. All of these currently have maliciously incompetent people in charge because Bolsonaro views these areas as opposed to his ideology.

Thanks for the clarification. This led me down a fun rabbit hole of understanding Brazilian exports. I would not have guessed that Lebanon and Saudi Arabia were the third and fourth largest importers of Brazilian beef after Chile and the Netherlands.
The part about Signal is inaccurate. Signal actually offers reproducible builds on their website, they don't want to publish on F-Droid at this time precisely because it wouldn't be signed by their own key, but by F-Droid's which would now just add one more party who would have to be trusted.
>composition

I know it's not what you are asking, but... the mitochondria are example of biological composition. They are organisms that (d)evolved to live exclusively inside eukaryotic cells, in tight symbiotic relationship.

Viral genetic inserts in our genome are another kind of composition. And then there's the gut microbiome, without which we couldn't live off of the diets we do.

Nonetheless, the inheritance aspect still is, and will remain, practical and worth taking about; saying "human IS-A mammal" is valid and useful.

There may be a hint here, regarding the current trend away from inheritance.
Biologists have long known that most microbes are "dark matter" in the sense that we don't know how to culture them independently.

There are all sorts of strange things such as huge rod bacteria that have lots of little rod bacteria living on their surface.

Many unknown organisms make themselves visible through their DNA, but without the ability to culture them independently we can't tell which are which.
Again, for the ones that don't have a side in Brazilian politics but do have a concern for the Amazon, and what the president may or may not do, I'd suggest checking out https://www.brazilianpoliticspodcast.com for unbiased political information/analysis on the country and its policies.
A comma separates clauses that make grammatical sense on their own, or at least where one of them does. So "In Greece, we have a similar phrase" is fine, because "we have a similar phrase" is complete in itself. Whereas "Readable code, is a piece of code" is not correct, because "is a piece of code" is not complete - it's missing a subject. Likewise, "In Germany, they say" and "In 16th century, in the Habsburgermonarchy" are fine, but "but let me, tell you a secret" is not.

As a native speaker, i can understand those sentences well enough, but they look wrong, and i wouldn't expect a fluent native writer to write them.

I have a Greek friend who is similarly scattershot with commas (eg "Hey send me, the photo of your office!"). I wonder if this comes from mapping some feature of Greek sentence structure onto English?

Because the builds are reproducible, it means that anyone can re-build the projects and verify that the output is the same, independently. That's the beauty of it, it's the only system that doesn't need a chain of trust.

That being said, I don't know enough about the project to say if there are actually people doing the verification work.
GF recently redid their concept, because the previous one wouldn't work (magnetic fields were far too high, which would cause liquid metal to vaporize off the plasma facing surfaces, hopelessly contaminating the plasma). The new concept uses slower compression, and has a solid metal conductor down the middle of the chamber. This conductor would experience enormous neutron loading (it cannot be shielded from that by a thick layer of liquid metal) as well as enormous forces from magnetic fields up to 100T.

I give this scheme very little chance of being workable.
Its more of a curse, than it is a blessing. The amount of false positives from small breezes is quite large.
Boeing is undermining its credibility through the promotion of such strategies. I am kind of taken aback that even after the death of >300 passengers, their attitude is to weasel out of the situation with a sham certification?

Of course, I could add "For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled", but then engineers hardly need to be told this, and the management thinks that as long as they can get away with murder, why even bother actually making a product, let alone a safe one?
> ...and then smashing the companies for missing the suspicious ones?

These legal efforts are the smashing you are calling for. This is what makes the decision to fulfill a suspicious order rather than report it a potentially costly one.
Elon has announced no such thing.
> We've observed that this becomes unsafe in places with high density populations, so lets prevent high density housing to maintain that lifestyle

This is a generalization that finds its roots in "white flight", which was itself driven by racism and fear mongering and the side effects of redlining and mortgage discrimination. Suburbs as we know them today didn't exist a hundred years ago. And in fact, perpetuating this belief drives more folks with money/privilege/economic mobility away from cities, increasing economic hardship (and in turn, crime) in the areas they leave.

You invalidate your own point. The south side of Chicago is not a place many people would consider safe, and yet it has a huge amount of single family units. "this becomes unsafe in places with high density populations" really means "this becomes unsafe in places with lots of poor people" or "this becomes unsafe in places with lots of people who look different from me".
Tech is more than just learning a specific system. It’s like the difference between a musician learning a new instrument and someone starting from scratch learning the same instrument.

The specifics of any one system are important, but rote memorization is only useful when you already have a lot of other skills.
From your link:

> the term “exceeds authorized access” means to access a computer with authorization and to use such access to obtain or alter information in the computer that the accesser is not entitled so to obtain or alter;

The information they were accessing didn't come from the computer. And this doesn't say anything about using a computer service in an unauthorized way, which is what it sounds like you're describing here
Yeah, I think the thing that confused me originally is that the headline talks about the serial numbers as "random keys", which to me implied something related to requiring the properties of randomness (e.g. evenly distributed).

But they're not random keys at all, they're just guaranteed to be unique. Uniqueness and randomness are totally different aspects, one that often trips up some developers who think that UUIDs (which are guaranteed to be unique) are also guaranteed to be random (not necessarily).
I'm 58, due to circumstances like taking a voluntary layoff 3 years ago, my nominal income an my then-spouses were about equal when we divorced a year ago. It's just plain costly to get divorced, dealing with legal system and legal system people is expensive. The higher rent/mortgage is nothing to sneeze at, either, at least in higher-cost-of-living metro areas.
Which computer system does this access that the user was unauthorized to access? The user's home server?!

The made-for-DRM CFAA that might classify fooling a flimsy filter as "unauthorized access to a computer system" is very much US-specific. Over here on the other side of the world, I'm thankful I'm not subject to such legislation or judicial system, but to one which still has a sensible definition of "hacking".
Out of curiosity, why? Zstd performs as well as it does because of the enormous effort that has been invested into it. That necessarily brings complexity.

The best way to figure out if you are an alcoholic or not is to meet other people who self-identify as alcoholics (or addicts more generally), and see if their stories ring true with you. It's only a problem if it's a problem for you - or for other people you care about, or for any individuals who end up suffering as a result of your drinking.

I am in no position to tell you whether you have a problem or not, but I know from experience (my own and others') that one of the reasons some people continue drinking or using drugs to excess is to escape from reality, so they can remain in denial about the mess they have caused in their own or other people's lives. This might not be you. But also, it might be you.

Lockheed enlarged their original concept, reducing the power density (counting the volume of the reactor, not just the plasma) by a factor of 100. It's now about 0.5 MW/m^3, about the same as MIT's ARC concept.

In contrast, the power density of a PWR primary reactor vessel is 20 MW/m^3 (and of the core alone, 100 MW/m^3). How exactly is fusion supposed to be cheaper than this, when the reactors are both so much larger and so much more complex? Saving on fuel is irrelevant, as fuel is only a small part of the cost of running a fission reactor.
I bet that viasat.com "connections" are given priority and not throttled for bandwidth - or perhaps since he never registered with the system, it never applied a throttle, under the assumption that blocking access negated the need for a throttle.
