rektide··on Goodbye Etcd, Hello PostgreSQL: Running Kubernetes with an SQL Database
These asks are so at ends with one another.

FoundationDB is not easy to set up. And it ships with near nothing out of the box; you have to build layers atop it's foundation to do nearly anything. But the polish is through the roof and it's one of the least likely systems to turn into a live hand gernade on the planet.

Etcd is a quite excellent piece of technology that is actually, relatively speaking, quite easy to set up, is quite polished, has few all in all drawbacks. It's great tech. But software alone isn't going to change the fact that you're operating a distributed system.

The biggest problem, in my view, is that there are so few opportunities to get any real experience with most of these systems. You kind of need to be running thousands of decent sized instances all at once to begin to appreciate the weirder sides of what could happen & what you need to do in response. For most people, many of these distributed db systems operate just fine. Until one day they don't, and then they are totally hosted & either suffering extended outages, rollbacks, or worse. Simple things like node rotations usually go smoothly, but don't generate the same kind of hard-fought experience. Your ask about starting out feels like it's asking for the safest most secure route, but only battle hardened rainy-day ordeals are ever going to actually get you to a place of comfort.

Hence... maybe just use postgres instead.

rektide··on Goodbye Etcd, Hello PostgreSQL: Running Kubernetes with an SQL Database
Operational experience would be my first guess.

A lot of folks already know how to backup, replicatie, & stream postgres quite well.

rektide··on Irish DPC says Meta's new Twitter rival won't be launched in EU
As nation's try ever so hard to dynamite the Declaration of Independence of Cyberspace & exert control wherever their citizens travel online, the difficulty in figuring out regulatory compliance keeps skyrocketing. It gets harder and harder to figure out how to meet each nation's requirements. And one nation's requirements for police access might conflict with another nation's requirements for data privacy. There's no international order, and 195 nations and countless provinces each get their say in making everyone trying to have a point of presence on the internet's life difficult.
rektide··on Google and HTTP (2018)
I'm sympathetic & way more agree than disagree. But DNS doesn't fill me with joy. It's quite centralized, quite a huge organizational vulnerability.

If we had some alternate addressing schemes in the browser that could do trust, I'd be much happier. Like, can dat protocol be a secure origin? Or like, if the goal really is just to secure users, maybe we need to let opportunistic encryption be something users can opt in as secure (even though it can be mitm'ed at the start).

Let's Encrypt has changed the game. It's great that https has so very very suddenly gone from frustrating & business class only to something even the casuals can easily do. But still, I'd love some less centralized systems for trust to be available, some visible known alternative paths demonstrating that there are diverse options at these lower transport/security layers of the network stack.

rektide··on Threads, an Instagram app
The main reason why is that Meta is a colossal vast data gathering beast, that for example flagrantly fucks around bypassing the GDPR. https://news.ycombinator.com/item?id=36583651

Now, I personally I think it's trying to swim up the waterfall & ultimately worse for everyone, but: Mastadon specifically has had a strong history of being anti-search, anti-scraping. You aren't supposed to be surveiling folks at industrial scale on the fediverse.

There's widespread skepticism about Meta respecting rules of the road. Having a huge giant shark join the pool of lots of little fish seems like a scary proposition. How we can still protect & have sovereignty over our different fedi-sites is a real question when there's a company with so much technical, economic, and popular leverages.

rektide··on Sao Paulo: A city with no outdoor advertisements (2013)
Far less offensive but the DC metro got screen ads & it just so cheapens the experience. Used to be a kind of impressive semi-brutalist feeling, which isn't super fancy or anything. But now just tacky.
rektide··on Can Dell’s 6K monitor beat their 8K monitor?
It's been pretty amazing how stagnant the monitor space is. I too am really craving an 8k@120 monitor, although there's a decent chance I'll balk at the price.
rektide··on Apple forced to make major cuts to Vision Pro headset production plans
To me it comes down to which Apple can more reliably deliver, that will see regular use. I have a hard time knowing what unique VR experience would keep people coming back day after day. But we know for a fact people use screens for desktop-like concerns for many hours a day. And we have lots of experience developing those experiences.
rektide··on Linux 6.5 Adding Initial Support for USB4 v2, Intel Barlow Ridge
Intel is such a hero of this world. They make so many amazing things happen. And they do the job well.

There's obvious/huge ecosystem examples: there was a whole industry around ultra-proprietary SSDs, and Intel rolled up their sleeves & developed & standardized NVMe to commoditize the technology, and then dropped absolutely killer products at a much more competitive rate.

But Intel's work pushing the Linux kernel forward is just amazing. They have so many teams doing so much, optimizing, & adding support. And so many of their products have great & readily available documentation, which is something very few other companies have.

rektide··on Rio terminal (Rust and WebGPU) released for Windows 10 and 11
Excited to see another very cross platform terminal!

I've been using Alacrity but copying to clipboard has been a nightmare time and time again, in all kinds of circumstance, and I switched out in despair just this weekend, but after two hours of debugging.

I first went to cmder (Windows only) but after an hour trying to figure out why astrovim rendering is a fucked up & getting nowhere, I gave up & tried Windows Terminal, which has been acceptable. Would love to be back on something more cross platform though.

rektide··on Apple forced to make major cuts to Vision Pro headset production plans
Apple has been smart to present it as a desktop replacement (as opposed to some ar/vr/metaverse device), which is something they can deliver that will let users bring their existing apps to the new medium without adaption.

Ideally yes apps should update themselves, tailor the experience. But the main focus so far has been pretty conventional app like experiences, which happen to be hovering in space. Where-as most headsets have tried to create entirely new ecosystems from nothing, and that would have been a huge mountain to climb.

rektide··on Douglas Rushkoff: Crashing Technosolutionism [video]
A major thread through the talk is that there are powers that be that think they have the answers & want to shape & mold us. Not super clearly stated, but implicitly said, it rarely works & the hubris almost always causes huge problems, is a projection rather than what the world wants or needs.

If AI is judging us, it's either based on data encoding our existing behaviors. Or it's crudely manipulated data by biased hubris filled megalomaniacs. The rest of humanity doesn't really have/isn't permitted much of a say in the matter.

rektide··on Ask HN: What new programming language(s) are you most excited about?
I'm exhausted by single-process programming languages. I think it's totally not worth our time to care at all about this problem any more. We need to figure out how to build systems more broadly. We're stealing useful energy pretending like such a small subproblem still has actual distinction & interest.

There's a lot of different ways to make code. But at this point there's just so little evidence that languages engender interesting new capabilities. There's some flourishistic differences, but most code reads fairly the same, if you squint. Rust is by far one of the most interesting languages, and it's only interesting adds are... constraints. We need some new frontiers of possibility, not just constraint. Languages are not leading us to new potentials, these days.

rektide··on Current challenges with using Linux in aerospace applications
The brother doest protest too much.

To me, it is exceedingly clear almost every other industry of this planet has far far better developed industrial practices and standards. They can go to school & learn how to do the thing.

There's simply no common accepted curiculum for how to actually build good software. There's too many possibilities, too many ways to success, and so few common threads that actually winnow down succes or failure. Software has a couple cobbled together Christopher Alexander style Design Patterns that can kind of inform some repeatedly usable ideas. And we have millions upon millions of libraries, each of which probably could become a library that is in the top 10% of usage, if conditions were right. But there's just so little rhyme or reason to it all. Software is all happenstance.

You can try to snark your way out of this & shade the difference out, but it should just be so obvious & clear. Software is not as mature. It's practitioners have infinitely more possibilities & exponentially less constraints. Most of it ends up working fair, in such a degree that it's near impossible to judge how far from optimal or how much better it could be working. Almost nothing else is so adrift, so unable to measure & understand how sucessful it is. This should just be clear & obvious. Your protests don't move me. It should be obvious.

rektide··on Douglas Rushkoff: Crashing Technosolutionism [video]
What a fragging amazing treasure. Rushkoff has just gotten better and better over time, more and more on point. Humble fun opening:

> I thought i was supposed to go out there to do this talk on the digital future & do this talk on the digital future - you know what I usually do -& just try to make people angry, you know- wealthy people upset by telling them people what this technology is for, and all that, and business plans are stupid, and killing the world....

Real talk middle, about the brutal indifferent stasism of AI:

> The dataset on which we are feeding our ai's is us. Is what we are actually doing. We have created a situation where we have a generation of very powerful children learning how to be, based on how we are.

> The only way to raise appropriately AIs is to begin behaving appropriately ourselves.

rektide··on Make Your Renders Unnecessarily Complicated by Modeling a Film Camera in Blender [video]
I'd also (re-)add: film is just one part of a transmission process.

Film has to be developed into something. And that's a chemical process, which is non-linear. Developer, the bath you put film in to activate the still blank but exposed reel, to turn the grains into actual "developed" photo, is a complex and local analog process. "Developer" is expended while developing film & becomes less effective at developing, creating a much stronger local contrast across pictures in a natural chemical way.

There's a pretty complex Shannon Information Theory system going on here, which I'm not certain how to model. There's maybe a information->transmit->medium->receive->information model between the scene and the film. Then an entirely separate information->transmit->medium->recieve->information model between the undeveloped scene and what actually shows up when you "develop" the film.

As you say, there are quite a variety of film types with different behaviors. https://github.com/t3mujin/t3mujinpack is set of Darktable presets to emulate various types of film. But the behavior of the film is still only half of the process. As I said in my previous post, developing the film is a complex chemical process, with lots of local effects for different parts of the image. There's enormous power here. https://filmulator.org/ is an epic project, that, in my view, is incredibly applicable to almost all modern digital photography, that could help us so much, to move beyond raw data & help us appreciate scenes more naturally. It's not "correct" but my personal view is the aesthetic is much better, and it somewhat represents what the human eye does anyways, with it's incredible ability to comprehend & view dynamic range.

rektide··on Sending audio to LKV373 HDMI extenders (2021)
People are amazing. I love this. Adore it. A thread of various awesome enterprising hackers, searching for truth, and using observability & tools to uncover meaning. Then bend reality to their whims & desires. This is the best human spirit. It's a pity technology so often obstructs rather than builds this human mastery. Alas! Never-the-less, humanity persisted. Against the throws of corporate-controlled limiting tech. Break out that wireshark & conquer in the name of freedom! Become great! Be unbounded.

I have huge respect for the Chromecast ecosystem, but there's so many weird prickly points for it. For a while I had a chromecast plugged in to a computer which then variously resent the output. This looks like a great way to do the same but simpler/dumber. One of the specific flaws of Chromecast is that if you stream a video, it can only go to a single device. Meaning my whole home audio does no good. Something like this could help me work-around that limitation. It's great how absurdly flexible these devices are, but it sucks enormous egg that Chromecast apps will only stream in the first place to signed Chromecast devices; this whole thing should be a non-issue I can software workaround. But a hardware workaround like this is adequate.

rektide··on Show HN: Project S.A.T.U.R.D.A.Y. – open-source, self hosted, J.A.R.V.I.S.
My skepticism at such overaching efforts is usually quite high. Apologies for discriminating on name/using popularity contest metrics, but seeing @grvydev's name on the repo is... great! They've become a proven master of web media already, pioneering low latency game-streaming with Lightspeed. They've selected really good off-the-shelf tech to work with for this effort. This is an effort I can believe in. Good stuff, go Garrett go!
rektide··on The world is watching in disbelief as France tears itself apart
This take is absolute classic Telegraph shit. My own tendencies lay way more in sympathy to the people, support protests, believe it's part of the great arch of society. I don't want to agree with this article at all.

And it's not this incident specifically.

I hate it, but I have some unease about tensions in general & how they manifest. I believe in the social contract, and I'm not sure how we can fulfill our obligations to ourselves, and how we can renew a sense of justice & improvement after things go wrong. I don't know the situation in France well, but in general, I've harbored some worry in the last 5 years or so that (often justified & honest & deserved) reactions can have large negative impacts on society, and I don't think we the world have the margins to soak these kinds of losses that we used to. Ideally the world would be more oriented towards sustainability, towards resilience, would have safety nets, and be better prepared. But it feels like so much of our social structures do - and i hate to say this, hate the conservatism this implies - rest delicately or precariously in balance.

I really so strongly agree with what you are saying. But I also want to find some way to find some permissible perspectives that recognize some of the nuance / scaredness, that can acknowledge some of the very conservative fear for the status quo & it's disruption, ideally without having to also demonize & counter-attack while doing so.

rektide··on 43% of white Harvard students are legacy, athlete, or donor/staff related (2019)
I don't know the term but you can also basically varyingly-indirectly pay to get in to most Ivys & other schools. I wonder what those admissions numbers look like.

I don't have a ton of info, but I've been at two different parties with people for whom this was semi-directly their job, to help facilitate extremly wealthy foreign students buying their way into top tier American schools.

rektide··on AMD’s EPYC 7J13: Zen 3 Customized
I can't wait to see a similar review of Bergamo/Zen 4c. Die shot analysis shows the cores themselves, not counting the L3 cache, are also 35% smaller than regular cores. But most of the specs look the same. There's a huge mystery here and there have got to be some interesting sacrifices.

Maybe maybe maybe 4c is chiefly a process tweak, that going lower power let them use more aggressive process scaling. Maybe. But that's still a huge die-space reduction that makes me think there's some secrets like here in this chip, that chipsandcheese.com was able to uncover with read deep prying/benchmarking.

I do wish the graphs in this article had a comparison processor or two. A regular Zen 3 would be great.

rektide··on Moneyball for Software Teams: Quantifying Dev Performance
> Some people really want to have a production line of developers hammering away boxes of value then can capitalize on,

Infoquake/Jump 225 series had an amazing fun-in-a-dystopian-way visions of this Taylor-ian model of programmers percussively hammering away on code.

rektide··on Make Your Renders Unnecessarily Complicated by Modeling a Film Camera in Blender [video]
Why stop there?

There was a great project that I keep forgetting the name of / link to... It simulated the chemical process of developing film.

I keep wanting to dig it up & play with it. Such a neat effort.

rektide··on Twitter now requires an account to view tweets
No one put it there.

We the people were inactive & didn't figure out how to weave together our individual & community sites to create a compelling multi-party space.

Or we could try to create alternative centralized but non-corporate systems. Not sure what other options there are.

I don't like where we are either. But new power has to be created. Hard work of figuring out protocols to converse across & usefully home our content/words on is sort of just beginning.

rektide··on The Rise and Fall of CORBA (2006)
On the one hand the failure is legit, success foiled by rampant vendorization & byzantine inscrutable tooling pumping out forsaken impossible to introspect generated code.

But also CORBA was maybe as far as I can tell the first programming tech to ever get canceled. That everyone went Vampire Castle on & decided collectively to crap on & lambast. What before CORBA had such a loyal hate club, was so bandwagon to disdain? It was a boogeyman tale, one we collectively whispered ourselves away from, even though most people had little sense.

It'd be interesting to try to dig up some of the old GNOME 2 efforts that did have Corba stuff in various apps & systems. Try to find some authors to say how they felt at the time. Go look at the code & see how it was.

The idea of having objects that can connect acriss boundaries is indeed super interesting. I love webdev & it's great, but we have noticeably not gotten very far in 20 years. GraphQL was one would be normalizing upstart, and ideas like resolvers have some merit, but it's still chiefly a state transfer system (which also has real time. Subscribe mode). It's still not really a well paved way to connect systems.

Even if we don't have distributed objects, just expanding the range of normative things we can do with resources on the web feels like it hasn't greatly expanded. Our efforts are still artisinal, handcraft by each team. We need to start figuring out, even if not distributed objects per se, how to grow the capabilities of online/connected systems pervasively.

rektide··on Google Sidewiki
Web Annotations spec is a great starting place & I hope we can some day see some real breakout wins from it. I'd love to see some cross integration with ActivityPub, as a syndication/transport!

What I really want is no site to win; true success doesn't come from centralized solutions. Each user should have their own annotation feed!

What I'd love to see is something like the return of blogrolls, an annotater's list of people they follow. Users promoting users. A good extension could let us do a N-degrees exploration, let us see comments of people we follow, people they follow, people those people follow... Expanding the network & implicitly suggesting to us other people we might want to follow.

I personally really really loved the social aspect of del.icio.us. Finding other people who were searching deep for interesting content was something I spent time on & it rewarded me handsomely, back in the day. I hope for similar thing here we're not just using this to have annotations, we're also using it as a content discovery tool, seeing what content there is from people we follow.

I'd try to suggest sites should have something like pingbacks, to make it so the site can keep track of annotations. But that would let them filter anotations which I don't like, and more problematically, it's an opt in mechanism. Having centralized search systems seems obvious. Ideally maybe some kind of kademlia hash might offer a P2p alternative. It's quite possible maybe bittorrent pex's P2p layer could be used/abused for this.

rektide··on Current challenges with using Linux in aerospace applications
Nothing else involves as much invention. We know intimately everything that goes into buildings & have built very similar buildings that serve very similar used millions of times. Each software has unique intent & is hugely hand crafted.

You cannot overbuild for software. You can over scale. But we don't have plumbing, electricity, foot, space, structural capacities as numerical behavioral properties that we can overshoot.

Both are complex but code is arbitrarily complex. The ways things can go wrong is unbounded.

rektide··on The problem with federated web apps
Axiom 2a of the web emphasizes this,

> a URI will repeatably refer to "the same" thing

And further,

> the significance of identity for a given URI is determined by the person who owns the URI, who first determined what it points to.

Which explicitly goes on to say ownership is not well defined because different schemes can have different behaviors.

https://www.w3.org/DesignIssues/Axioms.html#same

The trick is to actually have clients know & understand where instead to link people. If a server shuts down how does that alt-location get persisted & spread?

Effort has faced headwind, but I also really dig Signed Exchanges, which let's servers sign the content it sends & then bundle it together (WebBundles) so other servers can serve it in a trusted way. But the browser will only trust the content for 7 days, because as per this article, the dns owner might change & thats the security compromise. But an app could still parse & use that content, which makes extra sense now that we have Certificate Transparency expectations.

rektide··on The Rise and Fall of CORBA (2006)
I don't think of gRPC as object oriented, but I don't have a ton of experience with it. It seems like a service oriented system, with endpoints that accept parameters & return data. There's not, to my knowledge, much in the way of enduring objects.

You're not going to have dozens of Todo objects that you are callinng methods on. You're going to have a TodoService that has some methods. This is isn't very object oriented; the things sent in & out are just dumb data, it's just request/response.

I think cap'n'proto gets a little closer to having an actual notion of objects, in that the protocol has actual identifiers built in. But it's still more about services than objects.

Corba seemed to really be object oriented; you'd get back todo1 and call todo1.done().

rektide··on Lemmy now has over 2M users across 915 instances
Ah yes, the forever cry of fascism. 'Only centralized winner take all systems can ever win. Anything else is surely too difficult & could never ever possibly get anywhere. Because that's what my very important opinion says. Get used to hearing this call friends, it will be repeated verbatim forever, for surely your attempts are futile!'

Change doesn't have to come overnight, or even soon. Better is not on a deadline. Society can adapt & improve slowly too, in difficult not easy win struggles. This article is about 0.025% of the planet signing up, mostly within a couple months. To me, one that that ain't bad! The growth trend isn't likely to continue apace but this like critical mass, like a seed successfully germinating, for a long life, that can bring who knows what.

But of course overwhelmingly negative doomsaying 'it'll never work' is the tried & true forever response to all efforts to do anything other than a couple centralized megaproperties. Everything is too hard for users at scale. Only bad can win. Resign. Give up. Don't try. Unless you have 3b+ users you shouldn't even try.

This is just going to be the same point forever & ever, anytime anything good might possibly happen.
