AT&T’s Merger Could Be a Bad Sign for the Economy

I know what you’re saying sounds perfectly rational to you and I do applaud you for holding the moral position separating someone’s private life from their contribution to the company. But, think about the number of people who were let go for far less controversial actions. At some point an officer of the company doing things in their personal life becomes a distraction to the company’s goals. My question is, would you act differently if this person were not a co-founder?

Skills do matter. It’s just a different type of skill. Merit doesn’t matter - but even that’s a bit arguable - if the merit is decided based on what someone is creating value for their shareholders and value is entirely defined by stock price, it seems to be working well too.

(Not that I agree this is right)

We were building a payments system in the early 2000s and got a diktat to not use Oracle. The amount of things we had to build to satisfy the availability and durability requirements were so huge it consumed the first few years of work. We didn’t get to the business side of things until much later. Funny thing is we ended up giving up on MySQL and went back to oracle after all that work. The whole thing was scraped after a couple of years.

To get to the level of scale that oracle can handle we had to build sharding and cluster replication from scratch. It still didn’t get to even 1/10th of a single oracle node. Obviously we made a lot of poor architecture decisions as well - in hindsight, of course.

Metal is technically more elastic than an elastic band. With a Young’s modulus of 69 GPa for aluminum versus just 2 GPa for ABS, metal has the "memory" to snap back from significant pressure. Plastic, true to its name, is far more likely to hit its limit and stay permanently deformed. (That’s why metal bars are used to provide “flexibility” to buildings. Concrete provides the strength)

Article summary

Perovskites, compounds with unique electronic properties previously confined to specialist applications, could enable neuromorphic computers that process and store data simultaneously, as human brains do. Halide perovskites can form memristors, circuit components whose electrical resistance switches between high and low states, allowing them to function as both artificial neurons and synapses in brain-like computing systems. Researchers expect to assemble prototype neuromorphic networks using perovskite-based memristors and capacitors within the next year, though commercial success remains uncertain

Distribution agreement is generally different from a sale. Distributors act as agents of the manufacturer. It’s not yet counted as a sale. Most warranties are limited to first owner and do not transfer. How do you think this squares with that? Does it mean I don’t get warranty on the dishwasher I got from Costco? It’s also the same principle of a distributor acting as an agent that enables the manufacturer to have a contract with you.

AI's Dial-Up Era 9 months ago

Funny you would pick this analogy. I feel like we’re back in the mainframe era. A lot of software can’t operate without an internet connection. Even if in practice they execute some of the code on your device, a lot of the data and the heavyweight processing is already happening on the server. Even basic services designed from the ground up to be distributed and local first - like email (“downloading”) - are used in this fashion - like gmail. Maps apps added offline support years after they launched and still cripple the search. Even git has GitHub sitting in the middle and most people don’t or can’t use git any other way. SaaS, Electron, …etc. have brought us back to the mainframe era.

US: 335M / 5,000M ton / 15 ton

Indonesia: 275M / 650M ton / 2.3 ton

Pakistan: 240M / 225M ton / 1 ton

Nigeria: 220M / 110M ton / 0.5 ton

Brazil: 215M / 475M ton / 2.2 ton

I can go on and on about the countries that are emitting less than the US. People and animals live in areas that are liveable. So countries near the equator and fertile countries will always be more populous. So how else do you propose we compare countries? Which are themselves mostly arbitrary lines as far as the earth is concerned - so why chunk by countries? It has to be per person right?

I think it’s more like the “crash” that never happened with Uber/gig and crypto. I can’t tell if it’s just luck with one craze seamlessly enabling another in some cosmic coincidence or smart people being able to absorb the excess capital and capacity to pivot gracefully.

It’s basically similar to biking on rolling hills with each subsequent hill being a lot taller than the previous one. You come down the hill hard, but just before you crash to the ground, another hill comes up, and you let the momentum carry you through, and you also get a gush of wind in your back.

That’s what’s been happening since 2012 - it’s a great 13-year run now. I’ve stopped betting against it.

The attack vector is a 3pt app being compromised - maliciously or otherwise - that logs/collects the messages - i.e, the apps themselves can be a threat vector. To be blunt and honest, I’m not sure I disagree. The notification framework seems like an okay compromise to me. I have used it with my Garmin bike computer and I’m more than happy with the level of integration.

Kobo Libra color. If I’m being very honest, the screen isn’t as good as the oasis but it’s a compromise I’ve accepted for vastly superior hackability. I telnet into my kobo and installed tailscale then pointed the api to my calibre web instance, I have a much better experience overall because the books are drm-free(d) and calibre web handles sync with kobo really well.

And it has physical buttons. I was clinging to my oasis for the buttons.

Subarus use a boxer engine that drastically increases the visibility. I have a short torso with long legs and finding a car where I felt comfortable with visibility was a priority for me. I settled on the Subaru Impreza 10 years ago. Still has the best visibility of all the cars I’ve driven. I’d expect EVs to also have better visibility - may be eventually - since they can drop the height of the hood as well.

AppleCare now has monthly until you cancel plans - not just for watch but for phone and even the monitor. (I'm not sure of the macs). It's a bit confusing when you order and I'm not sure if it's because Apple is trying to discourage this; I just decline during order and then add it separately and this option always shows up for me.

Which is …normal. Different types of data access have different SLA requirements. Any company that cares about cost will warehouse data after x time frame. It’s done even in banking. Uber has a much more lenient need to make this data instantly available.

That's how I see it as well. In a layoff, the role is being eliminated as opposed to a person being fired. So they cut entire teams working on "unprofitable" products or certain roles deemed "redundant" within the product. You typically have the option to take a severance or apply for another role internally.

This is my understanding based purely on my experience getting laid off once - so take it with a huge grain of salt. The product I was working on was shutdown. I got paid a retainer to stay until the product can be properly wound down. Then got hired into a different role in a different team with a pay bump within a month. I got to keep the retainer as well - as long as I support the wind down efforts.
