I have a slightly older Power Mac G4, a 350MHz "Yikes!" PCI Power Mac G4 from 1999 (https://lowendmac.com/1999/power-mac-g4-yikes/) that I purchased in 2009 for $40 while I was a senior at Cal Poly. The reason I got it for only $40 was because it had a broken hard drive, but the sellers didn't know that. I was able to replace the hard drive with one that was given away by Cal Poly's computer science department, which sometimes gave away old computer parts. I also replaced the non-working optical drive with a new DVD+RW drive, and I upgraded the RAM; IIRC, it has 640MB RAM.

Even though the computer was already obsolete in 2009 (I used a 2006 Core Duo MacBook as my daily driver, which ran circles around the old Power Mac G4), it was a capable machine that could run Mac OS X Leopard and could handle the Web of that era, even YouTube videos. Eventually, sometime around 2013 the Web became too much for my Power Mac G4, but it remains a very nice machine for Mac OS 9 and early Mac OS X retrocomputing. I now have faster PowerPC Macs in my collection (a 1GHz PowerBook G4 and a 1.25GHz Mac Mini G4), but my Power Mac G4 is the fastest machine in my collection that could run the classic Mac OS without any modifications, and it is also the fastest Mac in my collection that has expansion slots.

I'm keeping an eye on 2019 Mac Pro prices (I own a 2013 Mac Pro, which I purchased refurbished in 2017 and used as my daily driver until 2022, when I switched to a Ryzen 3900 build). I love the aesthetic, but they're pricey since they are still quite capable Macs despite the transition to ARM. Once they drop to under $500, I plan to buy one and add it to my collection.

Update: I found my old blog post about my Power Mac G4: https://mmcthrow-musings.blogspot.com/2009/04/new-power-mac-...
403 would also be a weird error code for over capacity - 503 would be the correct error code.. The fact that it returns 403 as the error code is more proof that it isn't just 'service being over capacity'.
He made the initial diagnostic test sound like it has a massive impact on what you'll study. It doesn't. Even if MA thinks you know a topic well based on the diagnostic test, that doesn't mean you won't encounter it again. He seems to have missed the fact that every time you answer a question, this affects the estimate that MA has about your comfort with one or more topics.

The excessive focus on procedural fluency is a reasonable criticism but, as I said in another comment, this doesn't bother me at all. There are plenty of other sources for this. And procedural fluency is a good enabler for developing conceptual understanding.
This website design is blessed. A great return to the past
My 2004 17" PowerBook G4 starts right up. But it can't do much.
Cline's Framework for Optimizing Context, Maintaining Narrative Integrity
Yes, developers are of course going to opt for APIs that allow them to be as lazy as possible, forego proper backend security, and reduce costs. But is allowing developers to be lazy worth the cost of destroying user freedom? If so, maybe we should work on bringing back the Web Environment Integrity API. That would really help out web developers and would make web apps a lot more secure. Nobody uses Linux on the desktop anyways besides weird nerds so it wouldn't have any real impact.

Can't wait until we finally kill hacker culture for good. Everyone and everything will be fully secured. It's going to be beautiful. The nerds can cry about it all day long, but they're powerless to stop it.
Fun fact yum comes from yellow dog
I'm a bit puzzled by whether Fennel is trying to make "different things look different" as they claim, or not. On the one hand, Fennel separates Lua's multipurpose "for" into "for" (for numeric ranges) and "each" (for iterators). On the other hand... Don't macros and function calls, two rather different things with different powers, look identical in Fennel?

On the "Values" page, they also mention a macro that alters the lexical scope somehow. This macro is now deprecated, but its mere existence implies that such a macro can be expressed in Fennel -- that is, that it's possible to write Fennel code that causes what looks like an ordinary function call to do surprising things to the program state.

As they rightly mention (on either this page or the "Values of Fennel" page), the advantage of constraining a language is that you can more easily tell what a program is doing (and not doing) at a glance. But this seems to be undone by giving a pass to (unhygienic?) macros.
Use language features not considered “stable rust” that are later discarded and you will learn it is abandonware very quickly. In any case, you asked for proof and now have it. You should be saying thank you instead of trying to argue.
It sounds like you’re really invested in the idea that life was tough in the old days. I’m certainly not going to disabuse you of that notion.
Or Gemini Pro
Ok I’m genuinely convinced I’d be happier using Fennel than using Lua in instances where I need to use Lua. I’m not currently using Lua for anything. Maybe if I write a Pico-8 app…
I have had mixed results with iTunes Match. I like the idea of it, and it's good when it works, but Apple never really sorted out the streaming vs. sync-to-library thing. Most of my old playlists seem to have broken. Album art often gets replaced. And downloads are the same 256kbps AAC that Apple introduced in 2007 as iTunes Plus.
Please enlighten us
I’ll take a look, thanks for the effort!
The flip-flops are now coming so fast that the markets haven't even been open since things have changed completely multiple times.

Is chaos the true goal?
It's funny I'm about to go back the other direction - abandoning Mac at home to return to the Penguin.

After over 15 years I find myself using Windows and I hate it. What did they do to it? I used to love windows. The UX is nauseating. Little unseen action items that scramble your screen.

Slowly, Apple is doing the same thing to MacOS.

I never really left Linux, kept it on the desktop, but I got comfortable with the nice Mac hardware and Office suite. But now? Vomit.
Had a lot of fun reading that.

I'm a bit of a hoarder when it comes to technology, truth be told there's a certain rose tinted nostalgia that I get from thinking about early 00's technology.

It was still the era where UI's felt immediate and snappy- that anything related to actual computation or internet was jank and slow, but it had a whiff of a hopeful future about it. Every PC upgrade made things more snappy back then... Now I dread upgrades.

Hey ho.

It's endearing to know that one more bit of early 00's technology has been given a new lease on life. Would be cool to write some native software for it!
This tracks with my experience. I had to start from the very basics, but now I'm able to watch 3B1B and really understand what he's talking about. During lessons I occasionally reach to ChatGPT to help explain a concept or (rarely) a Khan Academy video.

I agree that the other articles mentioned didn't seem to give much of a chance. The Perhan thread has a comment chain between the author and the MA director [1] which is easy to miss. It's notable to me when users complain of negative XP, I've been working on MA every day for six months and got my first negative XP today! I've gotten 0 XP plenty, but if someone's getting negative XP often, they're half-assing it.

> I also wish they had a mascot and a streak feature.

I believe a streak calendar is coming based on the developers' Twitter. I dislike streaks but I imagine they will be optional as leagues are. I edited it out but my previous comment on this thread said "the day they get a cute mascot is the day I quit forever!" Maybe that was too harsh ;) But I do like the serious tone of the site as an adult learner.

lets no degrade lawyers more than necessary.

Business people hired lawyers to design means and methods to commit _implicit_ fraud and deceptive practices to improve the value of their capital assets.

Those lawyers then go on to sell this product to others.

I'm sure there's some lawyers out there that are going out there shopping this stuff around, but it's Capitalism and Business thats the active agent, not Lawyers.

Brightline in Florida is awesome. It’s not a short line, it goes from Orlando to Miami which is the same distance as New York to DC. Florida is set up great for it, with a series of pretty dense cities along the coast.
The MDD is the last Macintosh capable of natively running Mac OS 9. (Although, only just. It came with a special build that was just for the MDD.)

The fans in it are also astoundingly loud, and was often given the nickname of the "wind tunnel" Mac, because of the holes in the front.
You might be interested in the complexity metric from shape dynamics involving the ratio of intra-cluster to inter-cluster distances [0], the magnitude metric for maximal diversity [1], and haecceity [2] as repurposed for the meaning of entropy as specificity.

I doubt you were banned from 'reddit' with no chance of recourse. More likely that you were banned from a subreddit; site-wide bans are generally clearly explained.
It’s nice, I like it.

PS if the next question is whether I’d pay for it, the answer is likely no ;)

A suggestion:
I forget the HTML tag off the top of my head, but there is something you can do that turns off the keyboard autocorrect. Setting the search box input type to something specific or something like that… stock tickers aren’t dictionary words :)
Depending on how much time you have, the first thing I would recommend is to watch Karpathy's 'deep dive into LLMs' video (https://www.youtube.com/watch?v=7xTGNNLPyMI). It is 3.5 hours but it will give you so much instinctive understanding of how these things work and will likely save you a lot of time.

Purely from a technical standpoint, things aren't that difficult really. I'd recommend get yourself an API account with all major providers (because each frontier LLM evidently has their own strengths and weaknesses) and start experimenting with your data. The feeling you'll get when you first get an API response will keep you going! :)

Having said that, a caveat is, LLMs do hallucinate from time to time. If your data needs accuracy, definitely don't do the "throw everything at LLMs and let them do the work" but I'm sure you'll figure it out from trial and error. Good luck!
I don’t know if I’m doing something wrong, but Gemini 2.5 pro was substantially worse coding quality than Grok. Which is surprising since I’m working on a Golang codebase which I had assumed Gemini would excel at given that it’s made by Google
Well statistics shows that it is best to value equity at 0. I will take equity in a non public company. But not in exchange for cash compensation at my market rate.

Metigan – Email automation and broadcast with smart workflows
Hi HN

I just launched Metigan — a simple platform to send bulk emails with built-in workflows, personalization, and templates. It's built for solo founders, indie hackers, and small teams who want automation without the bloat.

Features:

Drag & drop email and form builder

Send broadcasts or automated sequences

Smart scheduling and custom workflows

Domain & sender customization

REST API + Webhooks

Free tier: 3,000 emails/month (no daily cap)

I built this after struggling with overcomplicated tools and unclear pricing. The focus is on clarity, full control, and speed.

Would love your feedback — especially on dev needs, pricing clarity, and feature gaps. Thanks for checking it out!

The FW400 MDDs are great for OS 9. I bought my dual 1.25GHz MDD G4 new specifically because it could still boot 9.2.2. Later I put a 1.8GHz Sonnet upgrade in it, and it's still my main Mac OS 9 development system. It also still sounds like a windtunnel.

Thank you! I love this about HN (well, I've been a lurker mostly for 18 years) that people point to things you haven't even thought of.
The fact that much of physics can be so elegantly described by math suggests the structures of our math could be quite universal, at least in our universe.

Check out the problems in the MATH dataset, especially Level 5 problems. They are fairly advanced (by most people’s standards) and most are not dependent on which N in the base-N system used to solve them. The answers would be different of course but the structures of the problems and solutions remain largely intact.

The best one already scores higher than all but the top 10-20% of most populations.
It's really not. The multi-chunk arena it describes at the end of the article is exactly the same structure as GNU obstack, except that obstack also bothers to implement the free-to-mark operation.

It's trivial to provide the operation for any arena, finite (just set the end pointer to the given value) or chained (a little more work since you have to free chunks until the former succeeds). The operation is O(1) if you're within the last chunk or two (and if you're tuning your chunk size well, you usually will be), O(log n) if your chunks increase in size as you go, or O(n) if all your chunks are the same size (not necessarily a bad idea for some use cases), where n is the number of chunks you're freeing (much smaller than the number of bump allocations).
Yes I would trade founder equity for an increased fixed salary. Statistically, equity is going to be worthless.
I also have a "trash can" mac, and I'm not sure what to do with it.

It runs linux great, and with 12 cores, 32G of RAM- it could be an extremely capable server. If not for the minuscule SSD.

It also draws a fair amount from the wall (98W~), which is probably the dual GPU's not having power control with Linux.

If only Thunderbolt 2 drive enclosures would come down in price a little.

Eitherway, I share your enthusiasm for the Intel "cheese grater" Mac Pros', those have got to be effectively e-waste to most people soon and I'd love to hoard some for myself.
To me that was the point of the puzzle.

Your suggestion would kill the challenge, turning the game into a casual dopamine inducer.
I didn't.
I even said that the premise was that people were self censoring outside of the censors. Clearly not though.

Grok is quickly becoming my favorite model just because it’s so verbose, but at the same time low on BS.

ok, so you're a mini elon musk pet that has good name recognition. The probability that anyone can replicate this ins the million+ employee mark is worthless, also.

so, anecdote.
I'm not a tax professional but this hardly seems necessary. Have you consulted with a tax professional to confirm that this is all necessary? How much of a difference does it actually make, i.e. how much tax do you actually pay to MI?
I had to search in Google, but IIUC the W-beams don't have the shape of a W. They look more like a rotated H.
Funny timing, I also bought a Mac today - an SE/30. Looking forward to fixing it up.

It's not. The chiclet PET keyboards are uniquely horrid. The later PET keyboards, however, aren't too bad.
From personal experience, the east Asian culture is not very immigrant-welcoming. It might change if population continues to shrink, though.
> like the monkeys and Shakespeare, there probably a limit to the value it can offer; but it’s not totally meaningless to try it.

Whenever someone uses this analogy, a question never addressed is:

Assuming sufficient monkeys, typewriters, and time, how
would anyone know if a Shakespearean work was produced
unless one reviewed *all* output?
> They’re banking on the damage either not being directly noticed by their voter base, or being able to convince their voter base that the damage is actually a good thing.

Are we really still at the stage where we seriously think this is how people vote? Its not. You just need to energize enough people in your sufficiently big enough bubble to believe in a cause and make sure that the other side thinks "both sides are bad".
Honestly that sounds pretty congruent with thinking about the spec from the position of the authors. Like what is the difference between "local time shift buffer" and "local hard drive" if it isn't some contractual authorization aspect they're pushing? Especially when you think that this standard is going to be deployed on TVs that will likely be displaying video from other sources than just broadcast.

So far you have made four posts in this thread and provided no evidence. Four opportunities to provide data on what you _feel_. Four chances to share links or reports.

And yet, here you are without of that.

As such, it is doubly clear, as described above, that you are insider trading. I hope that you are prosecuted to the fullest extent.
True! But it's crazy that the risk, successful startup didn't even beat established tech for returns.
I liked the game as it is in terms of hints and assistance.

The only thing I at one point missed was the undo action. I accidentally fat-fingered two correctly placed squares, and although it was frustrating at first, in the end I appreciated the additional challenge.
Will check it out. Thanks so much!

I'm pretty familiar with how LLM's work, it was more of "how do I create sites/apps" with LLM/AI backends. Will check out the youtube. Thanks again.
When I worked for the company named after a rain forest, we had the choice of sell to cover, sell all or pay taxes without selling shares. I always chose to sell all. I would never have taken 25%-30% of my hypothetical cash compensation and bought one stock. Why would I keep my RSUs?

Now I work at a smaller company doing the same thing (cloud consulting) making the same amount all cash. I much prefer that over cash + RSUs.
I've not evaluated it or ever worked with it myself, but CitusDB has been working on PostgreSQL horizontal scaling for quite some time now, right?

Does anyone have positive or negative experiences with Citus?
'Low-sugar' vaccine can provide broad immunity against coronavirus variants
Experimenters always were more skeptical; I hypothesized asking phenomenologists for a reason. I like Adam Falkowski's description of what it was like in [1] (about the end of dedicated SUSY working groups at CERN):

the existence of SUSY was almost a fact for a bulk of researchers working on the topic. This certainly was reflected in hiring practices, and you had a large group of top researchers whose entire publication list was tied to supersymmetry

These videos were a huge part of my linux learning experience, thank you for your work over these past years.
Another reason why tariffs are upheld is that its very hard to remove them. The moment you add them, you now creates industries and jobs that assume those tariffs existed.

Which is to say, if this ridiculous tariffs goes on for long enough, its going to be there forever. So you guys are, ehem, fucked.

Yes, Grok has become my go to model for general research and targeted coding tasks. Feels like its getting better over time vs ChatGPT which seemed to deteriorate over time.

Claude 3.7 is excellent, and better at coding but I appreciate the context size of Grok and feel like I get better bang for my buck for general purpose research too.
In response to the observation the average pixel color is surprisingly brown, I'll take today's opportunity to induct some of my fellow HNers into today's lucky 10,000 by linking Technology Connections's "Color is weird" video (https://www.youtube.com/watch?v=wh4aWZRtTwU).
I remember reading somewhere that maybe the purpose of life is to increase entropy in the universe. If that is true and we haven't found any sound evidence of life elsewhere, I don't know.
You'll need a case cracker and a tool specifically to de-energise the CRT: that's the killer part.
Congrats. Recap first - they're probably already shot. Once it's in working order, they're great little workhorses. In undergraduate, the local Mac fileserver was a very hardworking SE/30. I managed to loot its entire contents before they decommissioned it.
Reading through the thread, the point is the startups arn't providing transparent accounts of what the equity is and how it can be diluted and reduced over the life time and sale of the company. That's all the debate.

Many people have seen those options become worthless because of legalistic maneuvers and violate what's said in the initial options.

So this tangent isn't really clarifying anything. Some people would simply want larger salaries and options be valued as 0$ for evaluating compensation because how easy Capitalists have made it to screw over classes of options/share holders.
I'm sorry is the price of housing decreasing or increasing? You have to have a dual income household to afford a mortgage. You're really going to shit on young people because they dont have two incomes?
Right, they are not underwater. Hemimetaboulous insects like Holobates look like baby adults when they are born, and undergo multiple "partial" metamorphosis. In this case their wings are almost non-existent. They will go through multiple molts, gradually looking more like the adult. Holometabolous insects (e.g. beetles, wasps, butterflies, flies) are the ones with radically different body plans, often exploiting different niches, the larva could be aquatic, the pupa and adult terrestrial. Some more "basal" insects (dragonflies, mayflies) also have different body-plans at different stages, though instead of "larva" we say "imago", and things like that, for those lineages.
Why would I be a “believer” or missionary in a for profit company? It’s a business transaction. I give them labor and they give me money.
IME NetBSD or OpenBSD are better supported options on New World Macs. I run NetBSD/macppc on a G4 Mac mini and it "just works" (tm).
Coordinator of the authorization RFC linked in this post[1].

The protocol is in very, very early stages and there are a lot of things that still need to be figured out. That being said, I can commend Anthropic on being very open to listening to the community and acting on the feedback. The authorization spec RFC, for example, is a coordinated effort between security experts at Microsoft (my employer), Arcade, Hellō, Auth0/Okta, Stytch, Descope, and quite a few others. The folks at Anthropic set the foundation and welcomed others to help build on it. It will mature and get better.
