I'm a fan of ground based radio astronomy, however:

> there's no reason to put a radio telescope in space

sadly isn't as true as it once was ..

Once that constellation is fully expanded as intended, the planned chinese constellation joins it, and other nations (India?, the EU?) pile on, things will get even noisier.

The dark side of the moon offers hope, but it's still a lot of addiional awkwardness and expense that could be avoided with better attention to "the commons".

It depends.

If you have the power (as the post mentions - like a CEO) you can suggest, direct or butcher a project and no one would see you as a negative person.

But you can get butchered when you don't have the authority to poke around your concerns.

I would prefer to see the ship sink instead of shooting myself in the foot and risking my influence and credibility - as another comment on this thread said "Sometimes, you have to let people fail".

I suspect use cases are more likely community organizing and info sharing.
It supports forums and private groups that are E2EE, and "blog" posts that can include RSS reblogging.

The forums and private groups do bidirectional syncing and merging of all updates with anyone in the forum/group, so that gives you the equivalent of near-infinite multihop among trusted peers for large forums/groups. And it means every person has a complete copy, so it's nearly impossible to find all copies to censor it.
With the blogging of reblogged RSS feeds, you can even have people acting like news carriers for viral-ike person-to-person information transfer as well. Even if that does require a little more manual curation by the "transmission vectors" than forum/group posts.

Remember too that when things get bad enough people become ready to give up thier lives if necessary, and this may just be a way to reduce (but not eliminate) the need to actually sacrifice thier life for their cause. Large groups of people may collectively believe it's worth being individually captured and imprisoned or murdered to ensure the larger group is aware of what's happening.

Not to side track too much from this discussion, but I looked at that PolyMarket event: "US civil war before 2027?" Currently, it is priced at 91.3 USD cents for No. If you bet 100 USD, the payout for No will be 109.43. That is very good return -- ~9.5% for 12 months of lending (as PolyMarket required full payment at the time of trade). That is twice the (retail) risk free rate at the moment. I am actually tempted to buy a large part of the order book. Am I missing something obvious?

Also, if you enjoy troll humor, the comments section is very funny.

Very correct. Hell, OP is even thinking way too far out of scope for the goal on the request itself. They are thinking of their own progeny. The website doesn't need to survive 100 years, that implies knowledge of the site existing survived their death too. Only a method of seeing it, and reminding their children of it are needed, which honestly only requires the same attitude as keeping a an album of picture around.

OP could just get a box with a Raspberry Pi 5, its power chord, a mini mouse, and a built in mini screen. Seal it all off so nothing inside shakes. Congrats, you got your very own digital version of a personal memoir. The only thing now stopping this from working is The International Electrotechnical Commission somehow doing in the next 100 years what they couldn't the previous 120.

The screen can either, screw it, show the content directly, or MAYBE some indication of what a SSH connection is so the people accessing it have a way to figure it out. It's fine, the hyperfuture AI will do it for them.

Every 5 years, OP opens the box, and put in a new SD card with updated content, labels the previous one, and closes the box. Or, I dunno, swaps out the device for something else newer, if the IEC ninjas did come for him and forced everyone to use Wario Logo shaped plugs.

I think you need a bit of both. Hobby projects are a great way to solidify specific learnings. You want to learn CSS? Build a website! Simple, right? But we tend to build our hobbies differently, we treat them specially, and it's easy to get bored when they're no longer about the thing you wanted to learn about.

Building stuff for other people forces you to bend the project in ways you might not want to. It forces you to focus on their problems rather than your own. It also forces you to actually deliver. I've got countless projects that went nowhere once I was satisfied I'd learnt the initial, easy, 80% of the area. It's that remaining 20% that makes you an expert, though.

I've pretty much given up on traditional radio SETI ever finding anything, as its sole focus is on trying to find terrawatt/mega scale, repeating, intentional alien communication beacons, and nothing else. As I don't believe aliens would make such things, I don't believe traditional SETI will ever find anything.

Out telescopes aren't sensitive enough to detect the power levels of comm signals that aliens would use internally. Even if SETI saw a random powerful signal that happened to hit us, if the signal doesn't continuously repeat it just gets put into the "random transient, didn't repeat, who knows" bucket, and discarded.

The 100 signals they've detected will be looked at again with telescopes, and when they don't see the same signal repeating, they'll all just be discarded. Even if they were in reality actual emissions from aliens that we happened to see, if they're not intentional, repeating, comm beacons, the signals will just get discarded as unverifiable.

If aliens actually made terrawatt scale comm beacons, we would have easily seen them by now.

I also have a strange obsession with Prolog and Markus Triska's article on meta-interpreters heavily inspired me to write a Prolog-based agent framework with a meta-interpreter at its core [0].

I have to admit that writing Prolog sometimes makes me want to bash my my head against the wall, but sometimes the resulting code has a particular kind of beauty that's hard to explain. Anyways, Opus 4.5 is really good at Prolog, so my head feels much better now :-)

Just a few weeks ago I bought a pi5.

See my other comment, pi5 2 GB is about ~10% more expensive then when 3 or 3b got released when factoring in inflation. ~60 EUR including 25% VAT.

With PSU it's 77 EUR including 25% VAT right now.

4 GB version + case + 64GB SD + PSU = 135 EUR, but I don't need that much ram, disk space or the case. When I put it into a 3d printer I also don't need the PSU.

I see a lot of people defaulting to searchable PDFs for OCR, but depending on your use case (like feeding LLMs or long-term archiving), JSON or PDF/A might be much better. I put together a comparison of TXT, PDF, PDF/A, XML, and JSON to show the trade-offs in size, structure, and compatibility. Hope this helps anyone working on digitization!

It seems very unlikely the US would take the approach of shutting down the internet to prevent communication. All the internet infrastructure is hardwired for US surveillance data collection, so it's already a perfect honeypot. Why shutdown your honey pot?

More likely to be useful in the US is communication that is actually private, secure, and not centralized, but the underlying communication channel if unlikely to be relevant. Signal for example would almost certainly have thier IP blocked in the area, or their servers taken down because their completely centralized and therefore easy to block. Realistically something that can leverage an adversarial network to implement mesh communication that can be obfuscated (so it's not easily detected and blocked) is more useful in the US.

There are a few like this. You can bet on Jesus not coming back in the calendar year for a little pocket money.

Funny, because a bit like the civil war scenario, if JC comes back and someone is the sort of person to bet that he will, then do they really need the payout in those circumstances; and will the gambling website be in a position to pay out?

It's almost like you can take the other side against irrationality now directly instead of having to do it through some intermediary meme stock with borrowing costs and timing risks.

They didn't even. They announced a time-plan to stop buying Russian gas eventually. Russia weaponized gas deliveries and stopped delivering. In fact, even before the war and any "unfriendly" action by Europe, they underdelivered to keep the gas storages (which they owned) low and drive the prices up. This alone should make anyone not want to buy Russian gas again.

The fact that these threads are always full of lies with all these twisted narratives show you who's doing the talking in all of them really. This thread was a few minutes old when someone had to mention that "The US blew up the pipeline" and this shit doesn't even collect downvotes or gets flagged, it rises to the top.

I clicked on two accounts posting lies and saw Russian software companies mentioned in their scant posting history, which in itself is not a crime, but also a fitting signal.

The government isn't going to hand to do that, that's already what Google's planning to do anyway. They'd just have to tell Google to take down certain apps so they're no longer on the Google "approved" list, which would deactivate them on your device during next network connection (like most Google "services" on Android, I'm sure these too would bypass the system VPN as well) as well as making them unavailable from the sole allowed download source. You know, like they did with ICE Block already.

If your argument is that most Americans should be on public transit and save the average $500,000 they spend during their lives on private vehicles then I completely agree.

If you're saying "a less bad thing is still bad!" then your comment reads more like the "We should improve society somewhat. / Yet you participate in society. Curious! I am very intelligent." meme.

1. What's wrong with PDF? The format has been around for 30+ years now, and PDFs that old display just fine on any open-source PDF-viewing program now.

3. Redundant copies aren't going to last 100 years unless they're on some medium that can actually last that long, such as an aluminum (i.e., factory-made, not burned) CD. A flash thumb drive isn't going to last that long, not even close.

To me it appears as though the success of the right wing politics everywhere is that they made socioeconomically disadvantaged people identify other socioeconomically disadvantaged people and the middle-class as the cause of their suffering while somehow becoming sympathetic to the uber rich in hopes to one day belong. And to me it’s clear that if we taxed wealth and high incomes fairly and removed the loopholes to level the playing field we would not even need these discussions to begin with because we simply had a well financed social society and the rich would still be rich, but maybe not so obscenely so.

> At large companies, I've rarely found a reason to speak out on a project.

That's true. And it is currently one of the main reason why startups are so efficient compared to MegaCorps.

In small companies, it takes few engineers voicing out ' this is bullshit ' to stop a disaster.

In large corps, it takes 2y, 10M USD and a team in burnout to reach the same result.

And the main reason is the usual source of all sins: *Politics*.

I usually do night walks, talking to strangers, outcasts such as homeless people, street children, store or restaurant sales persons. I treat them food and talk with them and learn from their stories, I do this consistently that they know me. I genuinely love helping people, I also do ministries which I can say is very effective on helping people with depressions, they will learn to have a purpose in life or at least they will learn that some people are living life with much difficulty. I organize people I do not know and play sports I do not know how to play, and ask people to join. We do monthly activities which is optional for others to join our not. Nothing is forced but every one is welcome.

How does Briar work when a government shuts down the internet?

It mentions Bluetooth and Wifi.
My guess is that it tries to find other Briar devices connected to the same Bluetooth and wifi hotspot but what if the users are not on the Bluetooth/wifi?
Does it share ALL messages encrypted with every Briar user in the hope later they come in contact with the final user?

> Seriously, who does that?

That's an insightful question about Greenland, which Denmark desperately wanted to retain in the 1950s to the extent of unilaterally making it a 'part' of the Kingdom without consulting the Greenlanders.

Ironically it was only Belgium that spoke out, based on its own colonial dirty laundry.

If you're wishing your writings to be read by your children, why not print them on paper — and so in duplicate amounts kept in different places — and that will eventually be found by them?

I think, in your case, it would be easier to keep physical copies of those texts than try to keep a digital version of them up for a hundred years. And far less expensive.

Small things, mostly from skimming my amazon history. Nothing crazy, but all of these make my everyday life... smoother. Things that were a little bit annoying are invisible now. It stacks up. Raw links, no affiliates or trackers.

* Hakko FX888D soldering iron. I used to hate soldering, and it always came out awful. Perfect soldering is effortless now. It's a delight.

* Oxo 5lb kitchen scale (or anything similar). Cooking in metric is just sane. Excellent for bread.

* The Speakman S-2251 showerhead, with the flow regulator pried out. Was 100 when bought, 3x that now. Reddit voted it the most powerful and high quality showerhead. If you like that kind of thing, it's still worth it at 300.

* Schlage BE365 deadbolts. Can be found on sale under 100. Keyless door entry, supports multiple codes, not smart or connected in any way, battery lasts years.

* Velcro cable ties of various lengths. Every cable in my closet is orderly, and when you're done with one, it never sprawls or tangles.

* ESP32S3 boards. Drastically lowers the activation threshold for oneoff web-connected silliness.

* These little [dimmable lights](https://www.amazon.com/dp/B0D4Q4D5VP) (in amber). Warm colored, layered lighting all over the house. Huge vibe upgrade.

* [Dimmer leashes](https://www.amazon.com/dp/B07DL7V3CM). These sit between plug and outlet, and provide a separate 6ft cable with a dimmer switch on the end. I use them on my desk to control my zoom lighting, and in bed to dim my shelf lights without getting up.

* Multi-packs of small tools. We have a dozen pairs of scissors, box cutters, etc floating around. Sharpies and mechanical pencils in ~100 packs. Place around the house. It's very nice to not have to look far for these.

* [Masking tape](https://www.amazon.com/dp/B08R28DGHM) and stickers in many rainbow colors. Useful for knowing EG which cable goes to the PS5 (blue) vs xbox (green).

* [Giant digital clock](https://www.amazon.com/dp/B0DCVV8J98) w/ date, day of week, and temperature. Ended up buying more for other parts of the house because I got so used to looking for it.

* [Ratcheting adjustable belt](https://www.amazon.com/dp/B08VDMFZB2?) Also loops the belt tip onto the inside, not the outside. The idea of having a belt with adjustment intervals of inches instead of mms, with a tip that flops on the outside feels very silly now.

> What happens if you don't use the correct pronouns someone has declared for themselves? Is this not "imposing beliefs" on other people?

That's a false equivalence. All that's asked of you is to not misgender or deadname them, whereas transphobes are actively making it impossible for trans people to freely live as themselves.

It's also about not being a dickhead. If you met an autistic kid, and were told that he becomes incredibly distressed if you don't refer to him as 'Mr.', would you at least make an effort to call him that?
It doesn't matter how ridiculous you think calling a kid 'Mr.' is, he isn't imposing his beliefs on you by asking that of you.
If someone decides that their community will be a safe place for the kid to be, then of course they're justified in removing you if you refuse to call him 'Mr'.

Regardless of whether you believe trans people are mentally ill or just a normal part of humanity, not misgendering them is a simple courtesy to avoid causing a fellow human distress.

> "Feeling unsafe" is an outstanding weapon to crush behavior one doesn't like. Doesn't even require logic: it's literally a feeling.

How is this relevant to a programming language community? Who, in your scenario, is doing the crushing?

It's because it's easy and administratively simple, and it's easy to figure out how much you have to earn before you can actually bear the cost. In reality, it leads to a grey area where in the short term you're better off earning less to get the benefit, but it's eminently fair and easy.

And in general, increasing taxes is not easy, and the richer people are, the more able they are to fight against it. So we often create regressive tax regimes despite knowing they aren't very good systems.

I think it's what that intolerance leads to which is a big part of the problem. It's natural that we don't like being bored, but these days we have infinite means to keep boredom away that don't involve connecting with others. Why go through the risks and awkwardness of opening yourself up to others when you have a device of infinite rabbit holes and time sinks in your pocket at all times? 40 years ago it was very possible to run out of entertainment, which is quite different today.

> Once that bearing is gone the stress that it would normally allow to escape on account of rotation would be directly transferred to the metal around it

The bearing would have to sieze up and the bearing axle be locked to the race. There is some limit to rotational torque even with a siezed bearings.

Metaphor: arthritic joints are not smooth, but they will rotate if given enough torque.

From the images, it looks like the bearing had siezed. So presumably rotational vibration was transmitted to airframe and the vibration caused structural failure?

I'm assuming it is not an issue of extreme rotational torque causing the issue (and given it is a bearing the design is for very little torque there!)

The USA doesn't (over any long historical time) push for anything much like corporatism, but instead for capitalism ("corporate capitalism” or “crony capitalism” to those who view “capitalism” as a utopian free market system and not the concrete real-world system for which the name was coined by its critics, I suppose.)

The US has been pushing toward something blending corporatism and kleptocracy under Trump II, but I suspect that people using "corporatism” to refer to a longer-term effort of the US are misusing "corporatism” (where the body—“corpus”—actually refers to the aggregate of government, business, and social institutions, all of which are interlocking and working together, with interlocking formal control structures for that end) to mean “capitalism oriented specifically around the interests of corporations”, i.e., "corporate capitalism”.

I guess if you were relying on the meshtastic network as a backbone network replacement, which I'm not sure much of anyone is even currently setup for and I've heard isnt really feasible with the naive meshtastic toy implementation, you could be sending encrypted traffic. But then you have to have pre-shared encryption keys for participants and it will significantly lose it's usefulness for adding new adopters.

It wasn't my job so I didn't look into this fully, but the main issue we had was clients claiming that files didn't exist when they did. I just reread the NFS man page and I guess this is the issue:

> To detect when directory entries have been added or removed on the server, the Linux NFS client watches a directory's mtime. If the client detects a change in a directory's mtime, the client drops all cached LOOKUP results for that directory. Since the directory's mtime is a cached attribute, it may take some time before a client notices it has changed. See the descriptions of the acdirmin, acdirmax, and noac mount options for more information about how long a directory's mtime is cached.

> Caching directory entries improves the performance of applications that do not share files with applications on other clients. Using cached information about directories can interfere with applications that run concurrently on multiple clients and need to detect the creation or removal of files quickly, however. The lookupcache mount option allows some tuning of directory entry caching behavior.

People did talk about using Lustre or GPFS but apparently they are really complex to set up and maybe need fancier networking than ethernet, I don't remember.

Using modern femtosecond lasers, you can etch codes as small as 250 to 500 microns.

I use it for professional use, running production services which don't require 99.999 availability and have relatively low traffic, basically some internal dashboards and tools.

I develop my programs as deb/systemd packages and deploy in "fat" ubuntu/debian incus containers.

I have a cluster with three machines where one is used for build-containers and second for production containers. I am looking forward having time to have ZFS streaming incremental backup of the containers.

For big servers I use Proxmox, which is great, but Incus (and IncusOS) feel a bit more futuristic, where Proxmox is more bullet-proof enterprise solution.
