Inflicting some pain to sell Ubuntu Pro maybe?

bojangleslover··on Do dentists know what they're doing?
To pick a dentist, I simply ring them up and ask

1) Does the dentist still have student debt? 2) What's the ownership structure of the practice? 3) How many years has the dentist been practicing (correlated with 1)

bojangleslover··on A brief history of the Bloomberg terminal
There were two in the Greenwich CT library when I lived there in 2019, not sure if they’re still around.
bojangleslover··on S3 Is the Future, S3 Is the Past
> there is no fundamental technological barrier to building a true SSD-based, disaggregated storage service with the durability, capacity, and pricing profile needed to serve as a general-purpose replacement for S3

There are a lot of very competitive alternatives around today are largely unknown. For example B2 Overdrive by Backblaze boasting up to 1 Tbps, Wasabi offering byte-compatible S3 storage with no egress fees for reasonable use and Cloudflare R2 also with no egress, all priced comfortably under S3 before egress (which the the real kicker...how do you even put a cost on lock-in?).

Not shilling any of these. We use R2 and Wasabi as our storage backends...so we obviously like them, but are not paid to say good things about them.

bojangleslover··on AWS says it can't restore some data from mideast facilities struck by Iran
I think people are overthinking this. I'm the first one to criticize AWS (I run a competitor, carolinacloud.io) but I don't think we should hold it against them when they lost data due to their hard drives being physically bombed.
bojangleslover··on Ask HN: Why were OpenAI, Claude, and Grok simultaneously down?
I'm not sure if this is CF. Cursor, GCP and AWS had some errors. GCP AFAIK can route fully independently of CF. My money would be on a fiber backbone provider (Megaport, Zayo, Lumen).
bojangleslover··on Apple caught off guard by AI demand for Mac Mini and Mac Studio
What are you using for this? We tried this a few years back, could simply not find a good diarization engine.

bojangleslover··on We Rebuilt the Linux MicroVM Stack on Apple Silicon
This is unbelievably cool. How did you use AI for this? Absolutely not suggesting there's anything wrong with it - quite the contrary. I find AI is most useful for these lower level driver type projects such as yours that one knows are possible but that would be very onerous for a human to implement. For example the guy who re-wrote a driver from scratch for his HP Printer the other day.

Do you think you could have done this without AI? I've been migrating people off of AWS recently and it was absolutely made possible (or at least expedient) by AI.

bojangleslover··on Carolina Cloud pays SOFR on unused prepaid credits
The only way CC credits will expire is if I (the founder) die and my beneficiaries liquidate the business
bojangleslover··on Carolina Cloud pays SOFR on unused prepaid credits
That's not a like-for-like comparison. You need to compare CC to the c8a range of AWS, on-demand only. That's where the 1/3 comes from. For example:

c8a.medium (1vCPU/2GiB RAM/no SSD) on-demand on AWS: 5.39 cents per hour plus egress Carolina Cloud equivalent: 2 cents per hour with zero egress

If you don't have egress then the price is closer to 40% that of AWS. If you do have egress, the price could be far, far below 1/3.

Hetzner server auction is great for many use-cases, but it's not a fair comparison with EPYC Turins.

bojangleslover··on Carolina Cloud pays SOFR on unused prepaid credits
This is aimed at CFOs, not hobbyists
bojangleslover··on Carolina Cloud pays SOFR on unused prepaid credits
It's the case because once you buy cloud credits you are in an entirely unregulated space. At Carolina Cloud, that means your cloud credits are nothing more than an audited and backed up DB entry. Therefore, we can do whatever we want with them. We could double them every 6mo if we wanted. We settled on something more reasonable (SOFR).

Not unlike the hyperscalers giving $100k+ to startups and it not counting as income for C-corp tax purposes. Totally unregulated space!

bojangleslover··on Carolina Cloud pays SOFR on unused prepaid credits
This is correct, if you put in $1000 you could basically run a small dedicated VM in perpetuity.
bojangleslover··on Carolina Cloud pays SOFR on unused prepaid credits
This is interest on credits, not on cash. Once you start paying interest on cash you need a banking license. I think you'd be fine even in Europe paying interest on credits.

bojangleslover··on Ryanair dark UX patterns summer 2026 refresher
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.

bojangleslover··on Ryanair dark UX patterns summer 2026 refresher
>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

bojangleslover··on Ryanair dark UX patterns summer 2026 refresher
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.

bojangleslover··on Claude Fable 5: mid-tier results on coding tasks
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.
bojangleslover··on Agents can now create Cloudflare accounts, buy domains, and deploy
I don't understand the pessimism here. You never know the use cases for quickly and automatically rotating domains. There have always been bots, spammers and scammers. I'm interested to see what people build with this.
bojangleslover··on Pro Max 5x quota exhausted in 1.5 hours despite moderate usage
That's weird, I'm on the $100/mo and I use it for around 2-4hrs a day often with multiple terminal windows and I never even hit 20% of my quota.

This rules. Just closed on a bunch of data science I was doing on the Medicaid dataset thanks to this. Very timely, zero bugs.

Well done Trevor and team!

bojangleslover··on The American Healthcare Conundrum
The US has a high variance population. Aggregating the US into a single mean or median for that matter is a fool's errand.
bojangleslover··on The American Healthcare Conundrum
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.
