"Death of personal computing"

Renewed M1 Mac in 2026: <$400

Entry level MacBook in 2006: $1099

This hardware price spike is just a blip.

After reading their SEC filing I would push back on that slightly.

I think the main reason Ryanair is so cheap is that they get insanely good deals with the airports because they bring so much business to the region. Ie Alicante, a secondary airport, is somewhat tourist-dependent.

Ryanair makes a deal with the municipally-owned airport and says hey, we're going to bring thousands of Brits and Germans to you (with full wallets). The municipality gives a good deal in return.

There's also the 1.5x revenue multiplier from ancillary revenue.

Finally, they only own one type of airplane. Makes the maintenance etc easier.

Those incidentals would not increase your fare 5-8 times Oh I see what you're saying. What I'm saying is, what's the alternative? Another more expensive airline whose online check-in takes 5min instead of 10min? I'm contending that even with the dark patterns, my downside is only 1.5x cost, which is still far, far below a non-budget airline.

nor can the price difference to US be the base for your cost savings Yeah I agree it's not perfect — but as someone who used to live in the US it's a base for me

About 1/3 of their revenue is ancillary (the dark patterns are there to cause ancillary revenue).

I just flew from Bournemouth to Alicante on Ryanair for £50. A similar flight in the US (DC to Miami, for example) would be easily 5x that, possibly 7-8x. The dark patterns took me about 10min to click through. Doing the math, that means my time would have to be worth $1500/hr which is higher than the take-home (not billable) of senior partners at law firms.

Ryanair has severely improved my life, especially for my fellow sun-deprived Northern Europeans.

I have no idea how people are burning $2k. I pay $100/mo and it's built an absolute crap ton of stuff for me. And my co-founder uses it 24/7 as well. Maybe we spend too much time actually reading the code (risk or benefit? you decide). Or maybe I'm in the "massively subsidized" camp and the investors are about to go for our jugular. But $2k for a single project is several orders of magnitude more than I am currently paying.

"Per standard deviation, parental wealth predicts a child's adult income at least as strongly as the child's own cognitive ability"

Parental cognitive ability predicts both parental wealth and child's wealth.

It's neither capitalist nor socialist. If it were fully socialist you would have long wait lists but it would be free and there would be one payer. It is like this for Medicare and Medicaid which I've heard are a fantastic UX. But this is only the case for about half of Americans (the ones who don't pay for it).

On the other side, if it were fully capitalist you would be able to see the price and walk away if you didn't like it. This is what makes capitalism work. Your margin is my opportunity. Instead, the upper middle class, who pays for everything already, and is unable to use Medicaid, is forced to use a certain "network" of providers and never, ever sees the price upfront. This is the cornerstone of capitalism. Does the buyer like the price? If so, transact. It's completely not there. Instead, it's actively discouraged and banned, and the price is maximized post-hoc by the same entities who negotiate directly with the employee's employer. Ie, a quantitative shakedown.

He's an idiot. He pulled off one of the most incredible stunts I've ever seen. Not only does was he able to find and extract the gold over a mile down, which is incredible, he was also able to rally over 100 investors and raise capital. Ironically this is basically how capital markets originated, from shipping ventures not unlike this one.

He should have given the investors their money, taken his performance fee, and not spend up to half of his remaining lifespan (and probably around 3/4 of his remaining health span).

On the other hand, if he has grandkids and he manages to give them say 100mm instead of 20mm, he may feel it was worth it genetically.

What I do now is I make an MVP with the AI, get it working. And then tear it all down and start over again, but go a little slower. Maybe tear down again and then go even more slowly. Until I get to the point where I'm looking at everything the AI does and every line of code goes through me.

Currently moving Carolina Cloud to Kubernetes. I had built a custom orchestrator but really want the freedom of pod movement as well as KubeVirt's live migration capabilities. My ultimate plan is to open a second location in South Carolina at a cheaper colocation and then drain the nodes one by one, moving them to there, and leave my prior colocation. Kubernetes will make this possible.

Completely different situations. None of the MinIO team worked for free. MinIO is a COSS company (commercial open source software). They give a basic version of it away for free hoping that some people, usually at companies, will want to pay for the premium features. MinIO going closed source is a business decision and there is nothing wrong with that.

I highly recommend SeaweedFS. I used it in production for a long time before partnering with Wasabi. We still have SeaweedFS for a scorching hot, 1GiB/s colocated object storage, but Wasabi is our bread and butter object storage now.

The complexity is what gets you. One of AWS's favorite situations is

1) Senior engineer starts on AWS

2) Senior engineer leaves because our industry does not value longevity or loyalty at all whatsoever (not saying it should, just observing that it doesn't)

3) New engineer comes in and panics

4) Ends up using a "managed service" to relieve the panic

5) New engineer leaves

6) Second new engineer comes in and not only panics but outright needs help

7) Paired with some "certified AWS partner" who claims to help "reduce cost" but who actually gets a kickback from the extra spend they induce (usually 10% if I'm not mistaken)

Calling it it ransomware is obviously hyperbolic but there are definitely some parallels one could draw

On top of it all, AWS pricing is about to massively go up due to the RAM price increase. There's no way it can't since AWS is over half of Amazon's profit while only around 15% of its revenue.

Great comment. I agree it's a spectrum and those of us who are comfortable on (4) like yourself and probably us at Carolina Cloud [0] as well, (4) seems like a no brainer. But there's a long tail of semi-technical users who are more comfortable in 2-3 or even 1, which is what ultimately traps them into the ransomware-adjacent situation that is a lot of the modern public cloud. I would push back on "usage-based". Yes it is technically usage-based but the base fee also goes way up and there are also sometimes retainers on these services (ie minimum spend). So of course "usage-based" is not wrong but what it usually means is "more expensive and potentially far more expensive".

We have no egress fees but you're right about Hetzner. They're cheap. We aim to offer more value-added software to make up for it. Also that machine is in Europe, Americans don't like the latency (at least I don't), they have been known to shut people down (within reason).

Also I'm seeing that the most they can go RAM-wise for a dedicated US location is 192G. We go to 512 and will soon go beyond. I'm sure they'll get there soon but that's a consideration as well.

We have about 1000 cores right now.

We're really excited for the AMD EPYC Venice — 256 physical cores each -> 512 vCPUs -> 1024 vCPUS on a single board with dual-socket. It will probably be about $40k per machine with these RAM prices but we're definitely going to buy a few. A full data center on a single motherboard!

So we're limited on capacity since we own all our own hardware. Please do not use us for auto-scaling just yet. Our software would have no issue with us linking up other cloud machines such as AWS EC2 to our fleet and offering it there, which could help with auto-scaling, but we would not make any money on that and it would be a lot of engineering effort for us right now.

We don't have on-demand API-based bare metal provisioning right now. Sorry if that is misleading on the website. Our bare metal is OTC right now (over the counter).

For the rest of our provisioning (VM and container) I wrote the software myself. It's based on a Django app called the "master" that hosts the console and keeps track of who has rented what etc + a bunch of "host" nodes that listen for instructions from the "master". Pure python, the only thing that's in Go is the CLI.

I looked into Proxmox but ultimately decided I wanted full control. ZFS storage from Proxmox is something I do sometimes wish we had — going to offer s3-compatible storage very soon but I know Proxmox does ZFS out of the box really well.
