The rest is the standard new urbanist claptrap written by someone who seems to know nothing of the Bay Area at all. Some gems:

- Suggests strip malls replace parking lots with housing...citing the fact that vehicles occupy 8x the space of diners. Its freaking SAN JOSE who is going to eat at a restaurant with NO PARKING? Cue reliable HN responses about public transit...NO people in San Jose do not take their family out to eat by riding the bus. If you remove retail parking you just end up with no tax revenues and blighted plazas.

- The suggestion that infill development is cheaper since you don't need to do sewers etc. Wow okay now I know the author is from NYC...99% of San Jose's sewer infrastructure is probably 10 years past its replacement schedule...theres no freaking way the city will let someone increase density but ignore sewer work. In fact, this work will be substantially more expensive than new work in the middle of a field. No different than software folks - upgrading a running working system is much more difficult than greenfield development.

- Suggests schools have closed in San Jose due to under-enrollment. Uh no in many cases this is the result of mismanagement of funds sometimes resulting in lawsuits. See Alum Rock for many examples.

- Same tired citations of nefarious moustache-twirling NIMBYs...who by now have taken on the aura of a Bond villain.

The fragility of white men who lose their shit at the slightest mention of their race and gender is fucking baffling, especially when compared to the routine dehumanisation that black people or women have to put up with every day.
Artificial Intelligence: Human Helping Hand or Hidden Enemy to Mankind
What about the thread seems "fragile" to you? It didn't seem like anyone was taking personal offense to the comment, only pointing out that it was oddly irrelevant, as though the author went far out of their way to criticize white men. Certainly no "sense of alarm" or "ego". Seems like you've gone well out of your way to conflate an observation with a rather dramatic (and frankly offensive--I don't imagine women of color taking kindly to being called 'fragile', for example) emotional response...

How do you know it won't cure cancer? Marie Curie checked out some invisible physics and discovered radioactivity. Now we use it to treat cancer.

I suspect that practical outcomes and technologies arising from understanding dark matter will be huge.

Also, I think you're missing the point of astronomy. "astronomers" today are generally astrophysicists or planetary scientists, and they are studying fundamental, mostly invisible, processes and substances.
Can anyone chime in regarding the economics and cost savings of open floor plans vs. private per-team offices (or the like)?

As an employee working in an open space, their costs on subjective well being, quality of work & etc. are so obvious to me that I sometimes get upset that employers and I do not agree on the issue.
I don't know about a mass market - but I live in rural Oregon, and booking an appointment with a local tradesperson results in them showing up 4 to 6 months out - there just aren't enough of them. Sometimes you can convince someone to drive the 2-3 hours each way from one of the nearby cities - but most these guys don't relish 6 hours driving to install a fan.

So I use YouTube A Lot, and boy would I like to be able to pay someone to walk me through things. And I suspect there a a fair number of people in spots like me (if not so extreme). And I suspect there are a lot of Urban DIYers that occasionally get in over their heads and would use this service.

But quantifying this market would be hard.

I do think the ability to recreate the 3d environment, from the sensors on a device in the house would be pretty critical to this working. And the ability to show the customers in AR exactly what needs doing could be a difference that matters.

Still I'm not quitting my day job.
I'm not a physicist, but my basic understanding of the state of the science tells me you're simply incorrect. We can observe the effect of dark matter via gravitational lensing, and folks much smarter than me have devised studies to exclude differential behavior of gravity at classical and galactic scales.

Give me a recent and well supported study indicating that dark matter may be something other than matter, and I'll happily read it.

My understanding is that the existence of dark matter is uncontroversial among physicists, and that the best bet is some sort of WIMP.
Don't look so far. It's just cheaper. Also it gives managers the feeling they can avoid people slacking off because everbody see what you are doing.
> Neither Ruby nor Python support the idea of 'code is data'.

Well, Python and Ruby have an "eval" statement. So "code as data" is supported, but discouraged.
In contrast Lisp macros / "code as data" are commonly used.

Why is there a difference in culture?
Is the only reason, that strings are a lot harder to manipulate than lists?
Is there more to it?
Maybe translated code is harder to maintain and reason about?
Maybe debugging and profiling is a lot harder (this is true for C macros at least).

I have just shared one confusion that I was struggling with.

I found python and ruby much easier to read and pick up.
One reason for this is, that programmers are not allowed to define new irregularities.
Maybe this insight is helpful for others, who are getting Lisp as well.
At least this was my motivation for writing this post.
In Sweden all citizens get a unique 12 digit number at birth (where the last char is a checksum). It is used for identification and you can call the tax agency to find the ID of everyone. For the public sector it is a great value as a primary key but increasingly shops have started asking for it too. This means a lot of information is easy to aggregate from multiple sources and build profiles of people. I guess most people don't care.

One view of of thoughts is that there are 2 types of them: one type focused around analysis and problem solving, and a second type focused around the stories the "self" invents and gets absorbed in. This analysis also correlates with different brain activation patterns.

Many people's minds spend most of the time in the second type of thoughts("self"), and it can be very helpful to have less of those, both for peace and other psychological benefits, and for having more mental power and clarity for useful thoughts.

But in the context of ancient India, China, where eastern philosophies came from, people don't need that much thought most of the time, but spiritual qualities can be very useful in small interdependent peasent communities.

Just look at the numbers.

Indian aviation doesn't kill more thousands due to the great work that Airbus (mostly) has done to keep poor airmanship killing people.

But at the end of the day, look at incidents in India and it's clear: perhaps revert to trains. Yes, they have a poor record too, but proportional to numbers of journeys/passengers to death or accident, minor compared to Indian air carriers.

Fun fact: Air India is a state owned airline that has been bailed out with tax payer money multiple times. Attempts to sell/privatize the airline has failed too so far.
That's not impossible, but I tend to believe the experts when they say it's not likely (and have explicitly ruled out several such explanations).
Time from discovery of nuclear physics to nuclear devices was less than 50 years

Same for experimental planes to first commercial flights.

So it might take centuries, but it also might not.
You need more than this. The alternative is modified gravity, meaning gravity rules are different at different scales. Most people arguing against dark matter use that one example as their battle ground, aha, I can get the same result with just a tweak to Newton's laws.

It's when you add in all the other problems that a little tweak to Newton's won't be enough.
We have the same thing here in the UK (national insurance numbers) but one key difference to the US seems to be that we rarely need to disclose ours. You use it for tax related activities and that's all. I'm pretty sure if a shop asked for it most people would say no, because no one knows their own without looking it up, but also because it'd be really weird.
You would think this is true, but the mortality rate for c-sections tends to be higher because they are often performed in the presence of other extreme complications that contribute to the higher mortality rate. The mortality rate for non-complication (elective) ceasarian is actually lower.

The Birth Trauma Association found that mortality rates are lowest for women who have elective caesareans. [0]

Some people will completely change the way they converse once they find out you have X status marker. A famous elite university is one of those markers that triggers a good number of them.

For example, they will instantly switch from friendly to standoffish, or they will redirect the whole conversation to be about this new information, or will start treating their interlocutor as a superior, or asking for some advice/help, or...

It’s not clear whether they have some insecurity about their own education, or just curiosity, or what, but it can be a real drag.

A different group consider themselves to be similarly elite, and will also completely change their conversation when they find another of their tribe, e.g. start talking about how much better “we” are than those rabble in a clubby way. This can also be super annoying.

I assume something similar happens when people find out you are rich, or
won a prize, or have famous friends, etc., but “where did you go to
school?” is a more common ice breaker than “how fat is your savings
account?”

Deflection can save a lot of trouble.
I think this is just a definition issue:

>Discretionary

>Renters by choice. Attracted to the extreme upper end of the apartment market; properties generally of resort quality, clearly appealing to households capable of owning a residence, but choosing to rent, or households with substantial incomes, but without wealth. The luxury rental category primarily focuses on empty nester households, or more particularly, high net worth households. The renter-by-choice household is demanding; finishing detail and amenities included in properties appealing to this category must be of exceptional quality.

>A+ / A

>High Mid-Range

>"Lifestyle renters." The high mid-range category appeals to double-income-no-kids ("DINK") households holding income status similar to that typically required of discretionary property positioning, but not in possession of the wealth more probably associated with the renter-by-choice rental household category. Properties holding high mid-range status typically offer excellent finishing quality, and attractive common area facilities, and typically focus on an environment providing a more social experience.

>A- / B+

>Low Mid-Range

>Working professionals. The low mid-range household is typically composed of working professional, “gray collar” households (i.e. policemen, firemen, teachers, technical workers). These households, while renters-of-necessity, are inclined to apply some discretion regarding rental environment quality, and will opt for “adequate” quality of improvements offering reasonably attractive amenities in a good/convenient location.

https://www.yardimatrix.com/About-Us/Our-Methods/How-We-Defi...

They count anything in the high mid-range or above as "luxury" when clearly it's not. Anything below Low Mid-Range has "older" as part of it's description, so obviously no new construction will be placed there.

In my market the new apartment complexes are almost exclusively 2 bedrooms or less. They are very clearly for those with disposable income and no kids. Those that don't fit into that category move a little bit out and rent townhomes/single family homes.

What does the 't' stand for, though? I thought it was fast-ruby to start with https://github.com/JuanitoFatas/fast-ruby.
I'm not asking anyone to put the consensus on dark matter beyond doubt, only for people to realize that the consensus exists for a reason. Even the Wikipedia page for dark matter mentions alternatives, so it's not even an absolute consensus, and scientists have considered possibilities like "gravity is just different at large scales." The problem is, none of those alternatives can yet explain the data as well as the dark matter hypothesis.

But unless we apply the principle of charity to fields that may lie outside our areas of expertise, then discussion won't move beyond the typical middlebrow dismissals HN seems to be fond of.
All the reasons given boil down to “we didn’t want to mess with TokuDB”. The build process (requiring specific GCC versions, CMake, and a bunch of packages including Valgrind), the errno patch to task_struct, and the half dozen libc stub functions are all there because TokuDB expects userspace libc.

I don’t know whether the authors ever attempted to patch TokuDB itself (or streamline it down to the essentials for the kernel). Instead they appear to have just taken the entire userspace-designed library and hacked the kernel until it fit. It’s a halfway-decent strategy if your goal is to get the thing off the ground as quickly as possible, but obviously a real implementation would have to ship a modified TokuDB instead (it’s OSS, so it should be hackable!)

This is pretty common in academia, sadly. As an academic who has released some academic OSS code myself, I can say that often there’s just not enough time or motivation to fix a blob of code into a generally usable format. Often it’s released just so that we can say “hey we open-sourced it so other researchers can build on it/replicate our results”. This may be one of the reasons why academic ideas don’t make it out to the real world that quickly.
Depends on how you encrypt over HTTP.

You can achieve similar benefits of verification with PGP and similarly rich object level encryption.

Be careful of gotchas in how PGP or similar work, if you choose it (notable what is or isn't plaintext).

Object level encryption typically allows for better separation of concerns as it does not bottleneck to a unique domain:port to seperate encryption contexts. It also eases separation of public facing encryption risks from private internal ones.

If a public server is breached, all HTTPS traffic can be read, but if it proxies a more secure, perhaps simpler application environment (perhaps a microservice for the specific functionality), then that application environment is not affected by vulnerabilities in unrelated public facing features (like a backup microservice might not care about how to render HTML/JavaScript, so wouldn't be vulnerable to common web XSS attacks).

It allows other benefits like:
- it faciliates only user can decrypt data being sent (good for backups)

- intermediate services to load balance and block DOS don't have to be exposed to the plaintext data, only the necessary service that needs it

- many to many encrypted messages over one connection (TLS is many to 1 decrypting endpoints)

- intermediate caching and redelivery of messages can be done with ease

- it likely is harder to be at risk of bitflips (https://www.youtube.com/watch?v=aT7mnSstKGs)

- similarly verification of the data with signatures reduces risk of data corruption being missed that may happen during transport.

- you don't have to depend on the Certificate Authority model (which is questionnably secure given the history of revoked CAs), you can use your own trust store or your own web of trust that could be shared with appropriate third paries or the whole web.

- if others can think of more, please suggest them

The encryption can just be used for verification (signatures) and this is very valuable for trusted content distribution, especially if you want to scale it using third parties.

Because of these properties PGP or similar object encryption technologies often play a part in secure forms of backups, email, instant messaging, software repositories and handling sensitive data in more regulated industries (health, finance, etc).

Arguably, both TLS and object level encryption together are worth doing, as object level encryption may sometimes make it more obvious who the sender and target identities are and this metadata may in itself be of a concern to leak.

The technology spinoffs from DM-hunting are notable for the broader community.

The high-power dilution refrigerator that ADMX uses is of the same sort that the quantum-computing industry needs more and more of. Indeed, the students and staff being trained by ADMX are finding homes in both academia and across industry.

The high-sensitivity detector technology developed for WIMP searches have alternative use in nuclear non-proliferation monitoring. Improved detector ideas may continue to rattle down into medical imaging in the long run, improving some combination of sensitivity and dose.

The real prize, however, is what happens when the nature of dark matter is understood. It is a long-game play, but the technological implications might be on par with subjects like electricity, nuclear physics, quantum mechanics, etc. We won't know until we get there.

Ammo works too. Worked at a shop where they would have us transport a 1U server in a case that also held a single .22 round. You would fly to the location, pick up the server, and hand the bullet to the person working the desk to discard. Got the occasional dirty look, but prototypes were never lost. Empty case could be checked on the way home.

I think one reason may be that people are used to the "completeness" of physics; it's the science that people seem historically most ready to declare "done", and it does explain a lot very well. This may make it particularly unsettling to learn about this vast frontier of ignorance.
You can only replace what‘s already there, otherwise you‘d change the design (here orbital dynamics, thus attitude control system incl. all Math and software behind it) so much that you’re basically building a new one – and that was certainly not the goal of having an on-Orbit repairable satellite.
People somehow feel uniquely qualified to speculate wildly about theoretical physics. It's bizarre in a forum full of technical-minded people.

Any idea why they went with snap instead? There seems to have been a recent proliferation of new packaging systems -- which is fine. But, from an Ubuntu perspective I don't think they should be included if they're not integrated with apt (perhaps it is and I missed the memo?).

Digikam moved to AppImage, which sounds cool but adds a further system one needs to update, and the automatic update never worked for me (I think their package didn't include the necessary metadata?).

Having all application updates available in one place, and official packages be recent, is the 'killer feature' for me. I used to be a Slackware user, but when I migrated to slapt-get I realised I was done with rolling my own packages and checkinstall-ing them and wanted system where things were more managed - not having half the apps installed ad-hoc.

When you have to install a new system to get just a few apps it feels like I might as well go back to ./configure;make;[check|make ]install.

Seems we need an xdg install record with a unified app that calls the sub-system (pip, 0install, AppImage, shell script, dpkg, whatever) to abstract all that away.

Good point about the downloading. Warp-packer should have all the warp-runners installed locally with it. Or at the very least they should be packages you install depending on your target platforms.
I think the backlash against "experts" comes from the fact that way too many things get mixed into "science". When you look at fields like social sciences, nutrition and economics there are a lot of "scientists" that get publicity for results of very undisciplined work. They don't crosscheck their result for contradictions and often just seem to look for confirmation of their own biases.

This contrasts to most physics I read about. Physicists seem to make a big effort to reconcile all their measurements and if they contradict they admit that and say "we don't know yet".

So physics and other hard sciences suffer from being put together with a lot of other bad science in the public.
