A very interesting concept whose maturity is being raised. There are many sky surveys (some originally intended for NEO searches) that have been opportunistically mined for novel transients. It turns out that if you look, there is a lot going on out there: stellar flares, supernovae, blazars, gamma-ray bursts, occlusions -- as the article points out.

Here's links to the tech summary, and the overview paper, which reviews work presented at the just-concluded SPIE conference:

https://evryscope.astro.unc.edu/the-argus-array/
https://arxiv.org/pdf/2207.14318.pdf

The array (both prototype and projected final) is made from ~20cm telescopes. Such a telescope can't see very deep, so they are relying on co-adding across various temporal windows, up to 5 nights, to get to targets down to M = 23.6. Controlling the systematic effects (temperature, structural geometry, optical path) for a ground-based telescope across these time scales and equipment differences will be a challenge.

One very large facility (like this one, not yet built) in this space is Vera Rubin Observatory (https://www.lsst.org/about, formerly LSST). Rubin has much more glass, so it will see deeper, but its revisit time seems to be less frequent (once every 3 days), and it may not offer the real-time mode that this concept does.

A final observation: The funding for this concept comes from an NSF mid-scale innovations program (MSIP, https://beta.nsf.gov/funding/opportunities/mid-scale-innovat...). MSIP supports up to $30M-cost projects.

This is the same order of magnitude as support for renovating Arecibo was expected to cost, before that telescope failed. (https://www.science.org/content/article/astronomers-relieved... -- it appears the failure could have been avoided with better monitoring.) I'm just noting that to fund new stuff like this, the NSF does have to progressively retreat from older observatories.
”z-index: 10000” is a solution employed by people who have no idea what a stacking context is, and, consequently, do not know that one can define their own ”top layer” and have z-indexes inside that work completely separate from the rest of the document.

Just set ”position: relative” on an element and it will start a new stacking context, and stack it within the underlying context. It’s like having a card in a card stack be another stack of cards.

Ask HN: How to handle open source contributors that do “too much”?
Hello everyone,

An open source app of mine is being "hijacked" by a contributor, and I have no idea how to handle this the right way.

In a span of 6 months, they contributed a lot. During these 6 months, I wasn't careful enough while reviewing their PR (because of personal issues), and they took the initiative to change existing features and made the codebase "messier".

Since then, I started rewriting and cleaning everything, but they keep creating PRs with feature changes, adding features without discussing them beforehand, and it's frustrating, since they are creating multiple PRs a week, with more and more changes.

Reviewing their PR is becoming harder and harder, because I feel like I'm wasting my time arguing with them, as we don't have the same "view" of how should the app work.

I feel like I can't say no to them (or I don't know how to do so) because I should be grateful as they helped with some bug fixes, yet I feel like I'm loosing my own project.

How to handle this (without blocking them) ?
It's super easy: downshift into the wrong gear and let go of the clutch. That's the bulk of those cases.
Even worse, you cannot use a browser from mobile woth cookies deactivated, at least thta's what Instagram claimed the last time I tried accessing it using DDGs browser. I'm sure that overall nbers improved, I stopped bothering that very day. That leaves WhatsApp from Meta's apps, which seems to become Facebook's Excel: The only reason to use anything from that vendor in the first place.
Super cool project, and they did a really great job documenting the process.

That said, a hobbyist level CNC will not be able to make a functional lens. Tolerances are way too high. Maybe it'll be good enough for focusing light and burning holes in paper, but it's not going to be remotely close to photography level.
Security issues with software are "normal wear and tear." If you want something to remain secure you need to provide regular security updates. Assuming it's secure at ship-time, a remote-start keyfob is unlikely to be secure 5 years from now (not without regular software updates.)

This is distinct from something like heated seats where yes, if it works it works.
Stop calling tech illiterate, NPCs. Thats some arrogance. Apple has its market, and you are free to not use the devices if you dont like em.

> Even if you were right that AI research is only as good as the average non-EA-endorsed charity

No, my point is that funding a company that sells closed-source text and image generation APIs in partnership with Microsoft in the hope this will prevent cyberpunk is a much worse use of philanthropic funds than a typical aid agency that indulges in all the stuff GiveWell frowns on (not doing RCTs to measure the nutrition benefit of feeding the hungry, doing "donor illusion" because it's an extremely cost effective and considerably-more-honest-than-OpenAI way of attracting support etc.) Most interventions not classed as "highly effective" have more plausible claims to effectiveness than some EA darlings

So paying less attention to certain EA arguments will, ironically, result in more effective donations.

Now I'm aware that EA is a diverse movement and some people give all their money to malaria nets and are doubtful of some of the "longtermist" causes (and EAs make perfectly well-reasoned and well-evidenced arguments for malaria nets, although they're not the only ones making them). But that seems like a particularly good reason not to blog about how sceptics should shut up and donate their own money to their own causes rather than pointing out issues with the EA movement...
But some of their products were. Google Earth was an acquisition, Keyhole Inc, and one of their early investors was In-Q-Tel.
This is pretty damn cool...
For the target repo, only on the pull_request event[0] would run; nothing is being `push`ed to the repo, so it doesn't allow something like pushing an actions script that exfiltrates secrets.

I work in the Salesforce ecosystem, and love my job but funny enough I fucking hate Salesforce in so many ways.
The State of Central Bank Digital Currencies
There is a core duality to being human (for all except for rare cognitive outliers):

We are fundamentally a tribal species. Our entire evolutionary history—the thing that turned us into the species we are—revolves around our incredible ability to cooperate and share information. The basic unit of survival for our species is the tribe, not the individual. So at one very fundamental level, we must be around others to survive and thrive. We must subsume parts of ourselves that are unacceptable to the tribe so that we can be allowed to be one of its members. "Us" is more important than "I".

But at the exact same time, the tribe only wants and needs us if we can provide value, preferably unique value to it. So while we need to fit in to survive, we must also stand out in ways that the tribe finds valuable, explore where other tribespeople won't and bring back resources (physical, conceptual, etc.) that others can't.

The tension between these two opposing forces—to conform or to stand out—is, I think, one of the key pieces of being human.
Depends on what you want and how cynical you are. A relatively easy option would be a meta study. Pick a subject, get a bunch of studies about it and compare methodologies, results, sample sizes, types, devices used to run, os choice, etc. Works great if you have an interest and inclination towards statistics.

Ask HN: What hidden gem GitHub (or other OSS) projects do you rely on?
I spend a good amount of time looking through GitHub repos for useful libraries / tools for projects I am working on, usually searching for keywords and sorting by stars.

Does anyone have go to projects (libraries, tools or otherwise) that are under-rated from a stars / forks perspective such that they are not as visible as they should otherwise be?
if you need help to migrate feel free to reach out!
Yes, use pnpm ! I should mention meta-updater [1], which is a pnpm tool which allows to keep your various Json config files in sync across the workspace. Pnpm's own mono repo is a good exemple config of meta-updater which keeps TS project references automatically in sync with the actual dependency tree [2]

I wouldn't go that far. Maybe more like, now that Apple has the M2 chip, should they stop making devices and focus on music and entertainment? Subreddits would fundamentally change how HN is used and lower the diversity of discourse. Obvious trolls aside, I appreciate when someone offers a perspective I hadn't considered.

This is also a site filled with people way more knowledgeable about certain topics than I could ever hope to be yet still allows me to chime in from time to time because of the variety of topics that make the front page.
Nowadays, you code your grammar directly in the source language, and your parser library generates a parser at compile time as part of the normal build cycle.

Of course this works best in a language that supports operator overloading and compile-time operations.

In the old days, in C++, this would have been done with template metaprogramming, which cost various annoyances. Now no such workarounds are needed.
We’re probably good but maybe offer a way to avoid certain articles on your front page?

Also make the front page longer.
Sarcasm and jokes in text don't usually come across to most people due to the lack of context. No criticism intended.
> aircraft carriers need five miles to stop

The shortest distance that I stopped the Carrier while going at 34 knots (top speed) was 1.2 nautical miles (NM). This takes several minutes and involves Backing Bells (reversing the spin of propellers), which is hard on the engines. The command is “All Engines, Back Full, Emergency, Indicate 000 (or 999 as necessary)”[1]

However this was the only quote I found that said this though.

What is harm?
Haha yeah we implement 'soft time-boxing' by tracking git commit timestamps. It's not as stressful as having a visible timer and we won't block a submission that exceeds the recommended time, but reviewers can clearly see who took longer and their last commit within the suggested time, which helps to create an apples-to-apples comparison.

No candidate wants to be entered in the Hunger Games for who has the most time to sink into a take-home.
I think you just proved my point, no? I don't want to do any of this; I want to pay someone to do it.
That seems like disingenuous language. Climate change is akin to an avalanche threatening our town, and we're looking to shore up the retaining wall before the avalanche gets out of control. If the incremental changes do not build a sufficiently sturdy retaining wall we might as well not bother - we will have done a lot of work and the avalanche will still destroy the town. There's no middle ground when you're talking about an existential threat.
The wait is irrelevant if you can't afford it (or will destroy your retirement).

But, no, I had a non-urgent MRI within a couple weeks and I paid €0.
If you'd like to try, there is a way to get a free user account at pub400.com. That got me interested enough that I set out to get my own AS/400.

It took me literally years until I stumbled upon an affordable machine with licenses. The machine I got is decades old and was decommissioned in 2008, after a long life.

IBM created something revolutionary and did everything to keep the public away from it.

Very few people are stupid enough to swim with orcas.

Anyone ranting about this feature, has ever implemented an aria compliant website?
20 years ago there was no need for any of this. You went to tje farm, dod your groccery shopping and tgat was it. Or you didn't go there. Either way, farms did exist back then just fine.

Who on earth would expect a local farm shop to be on par with Amazon when it comes to inventory and availability data online?
> with 900 telescopes that by 2025 could watch the entire visible night sky

I assumed the entire visible night sky included the Southern Hemisphere. But the diagram shows all the telescopes in one location.

> the Argus telescopes will sit in a 10-meter-wide bowl, all aiming out a single skylightlike window in a dome. Over the course of the night, the bowl and telescopes will pivot slowly to follow the stars as Earth rotates.

Huh, I was imagining telescopes watching the entire sky simultaneously. This sounds like it will see just a tiny part at a time. So a star could go nova and the system would only catch it if it happened to be facing the right part of the sky at exactly the right moment.
I guess the only hope for seeing new non-toy OSes would be when hardware manufacturers move to a SoC and create a spec for it.

What an excellent show (although very weird and crazy too). The books showed what to me is one of the more interesting ways for an author to come up with a systematic system of magic. It isn't just saying a spell or anything like that. In the book (spoilers), only the most intelligent people can begin to take all the variables into account in doing a spell (hand signs, words, positions of the planetary bodies, temperature, humidity, constellations, phase of the moon, mood of the caster, and a ton of other things are all factored in and tables are cross-referenced. The author did a better job of explaining it.

In relation to your above comment I felt they did a good job throughout the series showing the difficulties in communicating amongst lowly people and entities and creatures that are higher up in the pecking order.
Bookstores and libraries would do. Many are also available online for free.
There's also an aerogel layer. That's probably what would keep most people from building it at home.

For Telecom Workers, Burst of Bubble Takes Heavy Toll
Speaking as an ex-scientist, I think Youtube really made some terrible decisions around this. Specifically, there has to be a mechanism by which legitimate scientists and doctors can communicate in good faith to the public, even if the message contradicts what the public health officials want the message to be.

But then, I've seen plenty of examples in the scientific community where the prevailing establishment tamps down on new ideas that later turn out to be right (see: almost anything involving RNA, ever)
HTML5 Web Notifications Test
Those are professional radio telescopes. OP was talking about amateur visible light telescopes.
Not OP but I also work on the OpenZiti project. Yeah that's basically the idea. The biggest difference is that the "VPN Connection" is basically entirely handled by the SDKs on both sides and only available to strong identities that are authorized to send data/act as the server. No IP addresses to worrry about, no ports to open at all not even to localhost. Those SDKs connect to the overlay network (the "VPN"), the network sends the bits to the server and you have a solid, zero trust MQTT connection with e2ee as well. Neat stuff.
You don't need social media for Internet presence. You only need a decent discovery system.

A propos, right now, at the end of the social media era, Google comes up with an interesting gesture.

Days ago TechChunch reported[0] that Google will be tweaking the parameters of its Pagerank. According to the report, the new "ranking improvements" seek to reduce low-quality or unoriginal content [which currently enjoys a high ranking in search results]. Google says the update will target content created specifically to improve search engine rankings – known as “SEO-first” content.

“With this update, you're more likely to read something you've never seen before", Google says. Of course, nothing revolutionary is going to happen, but it must have become clear to the finance department that there will be no way to sell junk links to advertisers if the target audience is disbanded due to the lack of original content.

Somehow the executives at Alphabet understood that a good anchoring of content in the results pages is necessary.

Seems like they are annoyed that the Conservatives can't meet the minimun standard requirements for governing a country. Seems accurate on many levels.
Somehow, repeatedly calling a guy a pedophile isn't defamation, but showing a video purportedly showing a car self-driving itself into a child is.

Git and Github both allow you to put whatever email you want. If you care about being certain who is committing to your repo, you should ignore the email and only look at the commit signature.

And that will still very much resemble most of today's OSes not only because that's what people know, but also because the development kit will need to run on common OSes, so the paradigms still have to be somewhat compatible.

As I noted, there is no need to concentrate the brine to such a degree that discharging it could be a problem. But even if you did, discharging the brine through a long, leaky pipe or hose would avoid creating any dead zones.
More seriously, I've looked into true EA and suddenly realized I don't actually care that much for altruism. Just like most people, I really don't care to save an arbitrary life. For instance, when I bought my iPhone 13 I tried visualizing a dying child and seeing if I cared to save this arbitrary child and while it was heartrending, I'd rather have the iPhone.

Yesterday, did the same thing with dinner at The French Laundry. Can't be helped, man, I don't care about random lives. But like the great philanthropists of old, I am happy to give away all but the first billion dollars I've made.

And I think most people are like me. Like, you'd be accused of being a boor if someone said they were planning on buying an expensive engagement ring and you offered this alternative.
This whole "consent" part seems to be a clever way of saying a license violation occurred. I wonder if they'll allow such subreddits when home creation is possible.
Because you press 4 buttons on a cloud console, or write a bit of terraform, and you have a consistent management plane for all of this, one that you can plug into any tool the very large ecosystem.

Then your entire engineering org just deploys things.

Need per-application network security policies? Done.

Per app IAM roles? Done.

Secrets management? Done.

Role based access control? Done.

Isolate services to different pools of machines? Done.

Per-app live-updating configuration files across your entire fleet? Done.

CPU, memory or arbitrary per-app metric based auto scaling? Done.

Want to run all this on cheap spot instances? Done.

Want path based HTTP routing within your cluster? Done.

Want an easy deployment mechanism with versioning and rollbacks? Done.

Want simple and consistent service discovery across all your servers? Done.

Want to get advanced and build custom resources to manage groups of other resources whilst taking advantage of k8s management plane in a consistent manner that just works with all the other tooling? Done.

Want to do all this fairly consistently on any cloud vendor, or even on prem? Done.

Want a large pool of candidates familiar with this stack? Done and done.

All those lead to non trivial savings, so you can actually focus on your product and not building a crappy version of Kubernetes by stringing together docker compose instances.

But yes, if you’ve got a single developer and you’re deploying by ssh-ing into a single machine and running git pull, it’s definitely overkill.
