> My biggest question is why they aren't putting tons of pressure on getting a telescope that can do gravitational lensing to see as far into space as possible ASAP. But again I'm probably just speaking out of turn not being familiar with the wider industry/culture/economics.

You are likely interested in the FOCAL project. https://en.wikipedia.org/wiki/FOCAL_(spacecraft)

> FOCAL (an acronym for Fast Outgoing Cyclopean Astronomical Lens) is a proposed space telescope that would use the Sun as a gravity lens. The gravitational lens effect was first derived by Albert Einstein, and the concept of a mission to the solar gravitational lens was first suggested by professor Von Eshleman, and analyzed further by Italian astronomer Claudio Maccone and others.

> In order to use the Sun as a gravity lens, it would be necessary to send the telescope to a minimum distance of 550 astronomical units away from the Sun, enabling very high signal amplifications: for example, at the 203 GHz wavelength, amplification of 1.3 x 10^15. Maccone suggests that this should be enough to obtain detailed images of the surfaces of extrasolar planets.

That 550 AU... for comparison, Voyager 1 is currently at about 159 AU and moving at 3.6 AU/year.

New Horizons is "only" 55.6 AU and going at 2.9 AU/year.

But its an interesting project.
I made a version of an offline first app using PouchDB and CouchDB running on a Digital Ocean server. And a version that used a CouchDB installed on a local server (Raspberry Pi).

There are a few ways to do that using those tools, and it's very easy to implement. I thought it was great, especially using a locally installed CouchDB, but my users didn't really care, and I mean not a bit.

I don't have any big corporate users but there are some pretty big businesses and I could not convince them to run a DB on their side. They did not want to fuss with it.

Some of them have been using my apps for over a decade and there's not been any serious issues of downtime so there is no sense of urgency even though I've made it clear that can happen, and the importance of having their data onsite, in their possession.

I use it for my own accounts on my apps. CouchDB makes that very easy to do by itself. It's a built-in feature.

I am looking for optimal storage engine(KV) which can store operational telemetry (temporarily) at source node. As we know, operational telemetry is generated frequently and need to merge similar operations frequently (little compaction). Once it reaches good amount of size (100mb), we can transfer it to dedicated time series database engines through various mechanisms. I am struggling to find a fast, write heavy, memory optimal storage for this.

RocksDB seems to fit few boxes but there could be much better solution as we don't need deletes/range scans sort of operations.

Any suggestions?

Well written article--clarification on how Meta uses it though. It is not Tao it is ZippyDb:
https://engineering.fb.com/2021/08/06/core-data/zippydb/
> "not the least of which is that these aliases prevent you from using ports of those actual commands in your PowerShell session, even if you have them installed."

No they don't. a) you can remove the aliases, b) you can fully specify the name e.g. "curl.exe" wouldn't trigger the alias, or "c:\path\to\curl" wouldn't either. I don't remove the aliases, so I don't know why "remove-item alias:* -force" is so bad. The functions are, what, mkdir and more?

> "And they are absolutely worlds apart from the commands they alias— pretty much totally incompatible."

This is a complaint that "all things must be exactly how I expect them" which is not going to happen in a completely different shell/language/environment.

> "And of course there's already a sane solution to this, by the way: a command-not-found handler."

And of course PowerShell has one:

https://stackoverflow.com/a/67453249/

> "All PowerShell has to do is tell you when you run `grep` and it's not present that there's this really neat tool built into PowerShell called 'Select-String'"

Yeah, no, command line utilities where I type "thing -h" and they go "-h doesn't exist. If you want help, type -help" suck. Thanks for nothing, technically correct but unhelpful nitpicking junk.[1]

What would you do if PowerShell had used "ls" and "grep" for its actual command names, not aliases, but they behaved differently from Unix shell `ls`?

[1] yes I am aware that it's not safe to type `-h` to random commands and expect it to be helpful and non destructive.
This is just objectively not true. Population-level data has been used to establish all sorts of things about psychological disorders. You mention your experience of parental abuse causing depression: it absolutely does! And that relationship was established unequivocally decades ago by showing the correlation between adverse childhood events and the development of depression.

One of your specific complaints is that depressed people do not report the causes of their depression very accurately. This is also true! The unreliability of depressed people is emphasized in the diagnostic criteria, and a good psychologist will probe for other underlying issues. But researchers absolutely can identify causes of depression by supplementing self-reports with objective data.

> The problem with the psychology field is that it has an obsession with "data".

Yeah, that's how science works. By collecting evidence you can make descriptive statements about the world. If psychologists didn't present data, they would be instead be rightly criticized for presenting data.

It sort of seems like you jump from the poor accuracy of depressed people's self reports to dismissing the entire field of psychology. Humans are complicated and messy, but we do know a ton about psychological disorders.

Ask HN: Best single resource you use for tech returnships?
As an addendum, this other question: My resume and LinkedIn profile show no work since 2019- why have no companies or recruiters targeted me with returnships- only regular jobs?

I'm in a position where I could use a returnship and I think many more people are now in that position because of the climate of the tech jobs market. But returnships are still rather uncommon. I've found that it's mostly big, high-profile companies that offer them but I would like to seek more options in other places in order to increase my chances of getting hired. What are some other online resources that I might be overlooking for returnships from more unlikely companies and organizations?

Most interesting. There are even easier and more direct ways to improve resistance to glaucoma; namely high dose nictotinamide (aka niacinamide aka non-flushing vitamin B3, aka NAM).

The key paper was published in Science in 2017 by Pete Williams, Simon John and colleagues in mice.

https://pubmed.ncbi.nlm.nih.gov/28209901/

Vit B3 at relatively high dose (1 to 4 gm/day) is now being tested in several human clinical trials for glaucoma and other forms of neurodegenerative and neurocognitive age-related diseases.

See ClinicalTrsil.giv

https://clinicaltrials.gov/ct2/results?cond=Glaucoma&term=ni...

Results are promising, but like most therapeutics the efficacy is likely to vary by genotype, disease subtype, age, diet etc.

I’ve been taking 3 g/day for 6 years and have noticed improvements in cognitive function (recall, speech speed). But I freely admit that this could be placebo effect or due to weight loss and more exercise, so take my n=1 uncontrolled trial with big grain of salt.
For what it's worth, I was also reacting to this assertion:

> The first step to overcoming depression is to discover what is making you depressed. If someone is still depressed, they probably don't know what is making them depressed, and so their "data" is just noise.

This was not my experience, and hasn't been the experience of others I know who have been depressed. The condition is often caused by an acute stressor, but in my case it was caused by a lack of social interaction and exercise during the pandemic. Trying to identify the "cause" of my feelings wasn't helpful because they weren't rational - instead I had to get out of bed, exercise, eat, and socialize until the episode cleared.
Thanks! It's sad that this is the answer, but I understand. I wish sometime we can access the base models of GPT-4 without the 'As an AI language model' guardrails!
This all presupposes that reducing big oh increases code complexity. In my experience, that's simply not true. Unless you are writing C without libraries, you are almost certainly dealing with a language rich in datastructures that easily reduce big oh notation while clearly communicating intent.

A dictionary will generally beat storing values as key/value in a list, de-duplicating and linearly searching on the key. If you don't believe that, then go ahead and pollute your codebase with List<Pair<Key, Value>>. See how fast that will be.

Heck, go ahead and use and manage a Pair<Key, Value>[]. After all, can't prematurely optimize by using a data structure that automatically manages growth.

Maybe just store everything as a giant String. You can just keep concatenating new values and searching for others in it. Why let those pesky types get in the way of easy to understand string manipulation and regexs? After all, don't prematurely optimize.

Hey, perhaps you should always just bundle and distribute perl with your applications and fork off new instances of perl since it has such nice regex capabilities. After all, don't prematurely optimize.

Have you measured that performance? Halt before you say it's a bad idea, because obviously we need to profile everything and make sure that starting new perl processes are actually slow. Can't be prematurely optimizing.

Rachel Levine (a trans woman) dresses how she does for the same reason I (a cis man) do. Both our brains have a notion of our own sex, and we conform to society’s gender norms consistent with that internal understanding. It’s completely different than people who dress the way they do, or get tattoos or nose rings to make a statement, set themselves apart as individuals, or thumb their nose at society and it’s rules.

> This is completely non-responsive to what you offered it as a response to.

Not at all. You characterized my position as “incel” above, because the people having all the kids mostly share my viewpoint. It’s the dominant view in Asia, Africa, the Middle East, etc. Liberal Americans are the most pathologically individualistic people in the world.

I stumbled into it by accident as a junior software engineer. They offered me a 3-month contract-to-hire job, but instead it became a 2-year independent contractor job for the company. Most jobs that followed have been cold applying to startup contract jobs from Craigslist or obtaining them from local word-of-mouth. It's very feast or famine, and not everyone can keep the momentum of new clients going. As for myself, I am planning to leave self-employed work for the first time in over a decade, for the relative safety of a full-time job (even with the current market situation).
the whole insistence on going with what they believe in, 'social apps bad' (and kinda just that, not really going deeper into 'what are the interactions', etc.), just makes this seem kinda off (and gives a 'collaborative confirmation bias' vibe). sure, apps exist, but is it 'apps' or 'people being social'. and they kinda touch on that, but still fall back to 'social media bad' as a clickbait headline. 'it's kinda not about that, but let me engage in clickbait anyway'.

'being on a social app' is a high level / ambiguous enough of a thing, that trying to tie a rise in 'communication availability' and 'people being online' to rises in other things, kinda doesn't connect. (well, not as directly of a 'cause-effect', muddled with all the various ways that 'use'/'online' can be.) sure, it may be 'screen time', 'time spent online', but then just say that, not like it's 'social media being there, at all'

if they want to continue milking that headline, great. i just no longer see 'pointing at social apps and saying social app bad' as interesting, insightful, or valuable, at all. it's saying nothing.
Correct, this is exactly what I was referring to w/ that sentence.

How expensive is it? My understanding is that it's not reasonable to train an LLM from scratch by yourself, and that if you want one that isn't just very stupid then you need to spend between hundreds of thousands and hundreds of millions of dollars. But if you don't want to train from scratch then you can fine-tune existing models for cheaper.

As someone also formerly in the field, I agree but also that’s sort of what funding agencies are for? You have finite funding, where is the best place to put that money? Yes you can find any number of astronomers interested in spending money better spent elsewhere but my impression of the field as a whole when I left was that there were far more genuinely important projects not funded than bad projects funded.
I always know I'm going to get a coherent and relevant argument when someone starts with a dictionary definition.

Most creative trades share a definition of clean that expands on #2, where 'foreign matter' includes items, not detritus. If you leave a toothbrush on your desk the desk is not clean, even if the toothbrush is still new in the wrapper. It can also mean 'cleared and ready to begin a new task', which is a step that would precede any mis-en-place work one might engage in before properly starting the task.

Clean means something beyond that in software. It's fairly well agreed upon. It's not in the dictionary. That doesn't invalidate it.
Eliezer Yudkowsky: Dangers of AI and the End of Human Civilization (Lex Fridman)
These agents, even in their embryonic form, are so powerful. The world is about to change. I'm convinced we're at the beginning of a massive exponential.
Eliezer often imagines scenarios in which AI systems avoid making major technical contributions, or revealing the extent of their capabilities, because they are lying in wait to cause trouble later.

Therein lies the rub for me. If you assume a machine can achieve a level of consciousness and intent, then you can imagine all kinds of disaster scenarios. This seems to be a baseline assumption is this group, because whenever I ask how a machine achieves consciousness and intent I get shouted down. No one has been able to explain to me how a machine becomes conscious and "lies in wait to cause trouble later." Don't you first have to explain human consciousness before you explain how a machine achieves consciousness? Without consciousness and agency, it's just a machine like a nuclear reactor with "fail safe" protocols we can build in.

Grossly oversimplified but most American kitchens built in the past 40 years will only be wired with 20 amp circuits (= rated for 80% continuous load or about 1900 W). However, I've never seen a 20 amp receptacle in a kitchen (until my idiot GC insisted on it because he doesn't understand the NEC), and pretty much any US spec kettle will only have a 15 amp (NEMA 5-15) plug. But… there will almost certainly be a few different circuits in your kitchen so pulling 3000 W (a.k.a. 15 amp * 0.80 * 2) isn't so crazy.

Whatever. My kettle is rated at 1500 watts and it's still quite a bit faster than the shitty gas range. And it'll keep water at temp for half an hour. And it's adjustable so I can boil water or heat it up for whatever tea or coffee. There's a pretty strong convenience factor here.

A 240 V kettle is probably not worth the hassle though, especially not if you want your local building inspector to sign off on anything.
Deletes (tombstones) shouldn't really get in your way if you don't need them. Similarly, range scans just come for free from SSTables being sorted. Archiving RocksDB SSTable files can be a decent strategy.

One thing to pay attention to is if your telemetry data is indexed by timestamp (i.e. you're writing to the keyspace in order), the compaction of immutable SSTables layers could be wasteful? Although, the author's nice example of non-overlapping SSTables key ranges suggests there may be minimal write amplification here too.
