jbotdev | 1 year ago | on: Tesla Auto Wipers: Why They Don't Work and Why There Isn't an Easy Fix

I get it, he’s trying to do everything in software (with the existing cameras), since software is “cheap” and can do anything in theory.

Unfortunately they keep showing how they’re in over their head with some of these features (like FSD). But it’s fine because their customers agree to keep beta testing while they figure things out on production cars.

Just like “this is the year of the Linux Desktop”?

I’d love to have an open non-profit alternative to Google’s productivity suite, but realistically it’s very hard to host those things outside a traditional for profit business. Building the open source software is the easy part, and has been done already. The hard parts are things like email deliverability, and getting people to pay for what’s typically a free ad-supported service.

Part of my point is the goal with such a system is usually to require less infra work/knowledge from your devs, but it backfires if you don’t invest enough in your abstraction.

The implicit goal of these abstractions is really to central knowledge and best practices around the underlying tech. Kubernetes itself is trying to free developers from understanding server management, but you could argue it’s not worth using directly vs. just teaching your devs how to manage VMs for the vast majority of organizations.

I don’t think you’re ever going to stop more and more layers of abstraction, so the best we can hope for is they’re done well. Otherwise you may as well go back to writing raw ethernet frames in assembly on bare metal.

It seems like they’ve gotten to the “holy grail” of deployment where developers don’t have to worry about infrastructure at all in theory.

I’ve seen many teams go for simple/leaky abstractions on top Kubernetes to provide a similar solution, which is tempting because it’s easy and flexible. The problem is then all your devs need to be trained in all the complexities of Kubernetes deployments anyway. Hopefully Uber abstracted away Kubernetes and Mesos enough to be worthwhile, and they have a great infra team to support the devs.

jbotdev | 2 years ago | on: Go Package for Building Progressive Web Apps

I think you’re confusing Progressive Web App (PWA) with Progressive Enhancement. PWA is basically a web app (typically an SPA) that behaves like a native app, as described in the MDN page they reference. Loading progressively such that the page is still useful without JS is Progressive Enhancement.

jbotdev | 2 years ago | on: Hackers stole access tokens from Okta's support unit

The post glossed over how exactly they detected session hijacking. They mentioned “This detection looks for suspicious sessions appearing without an authentication event that are consistent with session hijacking.”, but authentication obviously happened at some point, otherwise the session wouldn’t exist. I’m guessing this is a complicated way of saying the IP changed since login.

Of course the easiest solution is you shouldn’t voluntarily share HAR files for an active session.

jbotdev | 2 years ago | on: Ask HN: Why has no one replaced Ticketmaster?

It’s weird to complain about supporting AEG claiming they’re somehow the 2nd “monopoly” after LiveNation. You can only have one “monopoly” in a given industry, otherwise they’re both just close competitors.

Having a close second competitor is still a step in the right direction, even if you disagree with their business practices.

jbotdev | 2 years ago | on: Google opens Falcon, a reliable low-latency hardware transport, to the ecosystem

It sounds like this builds on top of Ethernet to provide a higher performance alternative to UDP/TCP, with some sort of hardware acceleration.

I may be in over my head since I’m not an HPC/datacenter expert, but not sure I understand how you’d use this on the software side. Maybe someone is aware of specific examples? (beyond the vague “HPC/AI”)

edit: as another comment mentioned, the diagram shows it’s on top of UDP/IP, so it’s mostly an alternative to TCP/IP

jbotdev | 2 years ago | on: ChatGPT’s system prompts

Technically that’s always been the case. It’s just that now you can tell the computer what to do in a “natural language” like English instead of a “programming language”.

jbotdev | 2 years ago | on: The Twelve-Factor App (2011)

It is true that this is somewhat influenced by how Heroku works, but ConfigMaps and GitOps do not meet the same security and usability requirements as Heroku config/env vars.

If you want secure config storage on Kubernetes, you end up using Secrets, which ends up being key-value like env vars anyway. If you want similar security with Git you need a layer of encryption, which breaks diffs and requires additional tooling. This all leads back to why high-level deployment tools like Heroku were created.

jbotdev | 2 years ago | on: Think that your plastic is being recycled? Think again

I wonder why there hasn’t been more effort behind replacing single use plastics for food/beverages. People get all up in arms about plastic straws, but then stick their paper straw in a big plastic single-use cup.

I also find it sad that some companies like Snapple are regressing, changing from glass to plastic bottles.

jbotdev | 2 years ago | on: Show HN: Shuttle – Build and ship backends without writing infrastructure files

Seems ironic that you’d use rust to “build fast”. My impression is that Rust is more about building things safe/correct and efficient, with developer productivity being lower relative to other modern languages.

That said, the “infrastructure-from-code” idea is interesting. I’m not a big fan of coupling your code to your infra, but I’m intrigued by the idea of inferring infra dependencies from existing application code.

jbotdev | 2 years ago | on: D.C.'s ban on cashless businesses takes effect

I’ve actually run into this more with debit/cash accounts than with credit cards. I’ve had checking accounts frozen, but I’ve never had a credit card entirely suspended for “unusual activity”. At worst they’ve declined individual charges until I called, or I just switched to a different card, since it’s easy to have many redundant credit cards.
