BIMI certificates cost over $1,000 / yr right now. For me that's a feature. I wish the fallback in my mail client was a big untrusted symbol rather than sender initials when they aren't in my address book.

Eric, do you recommend, as you hinted in the book, that half of board seats should be appointed by a workers council? Do you think Six-Sigma is net destructive to a company, and why? Which examples in your book do you recommend readers further research and understand?

I read the book last night. While the topic is important, I was disappointed in the content and format of the book. Scatterbrained. Some of the most important questions get a page of content. Scores of offhand comments and examples that get no serious treatment, sometimes contradictory. The topic would have been better served with less examples.

Q3: Direct question: Have journalists and their industries been similarly corrupted from their proclaimed mission to communicate the truth? Do the issues in other groups of people (charity, religion, sport league) share the same root causes, or is the source of corporate corruption unique or at a different scale?

My book arrived today.

Q1: You have done a few friendly interviews on YouTube, but I haven't seen one that challenges you much. Do you know if there are upcoming interviews that you found pushed back?

Q2: Is the idea of shareholder supremacy fundamentally at odds with your with your preferred alternative governance structures, or is it just a time preference and risk attitude issue?

Q3: You will get sympathetic ears easily due to the subject matter. But the same book about non-profits would be a harder sell. Do you agree, and if true does that say something about the marketplace of ideas?

This is more likely due to the digital markets act that requires them to open their platform to competitors. hence it only being restricted on phone and iPad.

They wanted to rebase onto a different database first to make multi-region easier, but that work took many years.

Benchmark dataset fits in memory. Not a good test.

How many watts is that setup? Cool you got it to work, but maybe only useful for vintage / retro computing rather than practical if the energy consumption makes it economically wasteful.

I have not heard about UK Open Banking rails for merchants being popular. You are talking about P2P? the article is about challenging Visa/Mastercard.

This is the EU equivalent of Zelle, but pushing into merchant payments and owned and run by the banks.

When the telcos tried to compete with the cloud providers by offering OpenStack they learned the business wasn't as simple as offering 10-15 services with some racks. I can imagine the same hidden complexity for payment rails

On the other hand regulations have taken too much power away from merchants and Wero could succeed with more merchant friendly terms. They are doing 3-legged payments so they are not subject to as many European regulations as Visa/Mastercard.

I found Quint to be a good pairing with LLM. Easier syntax to learn so you are actually collaborating instead of relying on hope.

It uses http/2, it has streaming.

With ducklake this scales well to multi-terabyte data sets. The big benefit of this server protocol is sharing a high memory server and taking advantage of a shared cache for recent data.

your architecture page is empty. https://getkloak.io/docs/architecture/overview.html

For security products trust is important. writing your website copy by hand will help you build trust. If the design and content does not look human written it will lower adoption.

arpinum — Sun, 19 Apr 2026 10:54:47 +0000

I said worker/lambda invocation, $0.30/m cloudflare vs $0.20/m for lambda. Total cost depends on async work and memory needs. Cloudflare is $20/m seconds, lambda is $1.66/m seconds, both at 128MB. lambda isn't giving you a full core, if you need CPU it is also $20/m.

I think by operation they mean `git clone` or `git push`, which can read or write hundreds or thousands of objects per operation.

The pricing is disappointing. I'm surprised Cloudflare has not tried to compete on price against AWS lately after a good start with R2. Queues, database storage, database writes, worker invocation all more expensive than the AWS offering.

I read the code. It's a good case study of one-shot output from AI when you ask it to replicate a SaaS product. This is probably better than most because MotherDuck has been open about their techniques to build the product.

Obviously not a production implementation.
