coverj··on Infrastructure decisions I endorse or regret after 4 years at a startup (2024)
not possible: - workloads over 15m for lambda last time I checked, unsure on other providers - if you are looking to do anything stateful

possible but not ideal/inconveniences: - cold starts can hamper latency sensitive apps (language dependant + there are things you can do) - if you have consistent traffic its not very good value for money - if you value local debugging

coverj··on A staff engineer's journey with Claude Code
Are there even non-AI development streams/videos that meet this criteria?
coverj··on MCP doesn't need tools, it needs code
I'm interested why you aren't using the actual context7 MCP?
coverj··on Ask HN: What are you working on? (May 2025)
I think a lot of people in office jobs day dream about this sort of thing. My father-in-law is a third generation farmer producing ultra fine wool. I am a source of free labour at shearing time and I will tell you that when I treat myself to a sleep in on Monday morning and roll out of bed for standup at 9:30 I sit there with the biggest shit-eating grin on my face meanwhile my father in law is already 4 hours in to his 12+ hour day.

Also if I was to go into farming I'd have to do something with crops/fruits/vegetables. I am a bit of a softie but the realities of livestock husbandry when met with the economics of farming can be quite confronting.

coverj··on Migrating to Postgres
I didn't mind prisma for managing the schema etc but also seen your linked github issue. I found other people recommend combining Prisma with Kysley. I have only used this in toy projects so take this with a grain of salt.

coverj··on A flat pricing subscription for Claude Code
are people really committing 5k lines a day without AI assistance even once a month?

I don't think I've ever done this or worked with anyone who had this type of output.

coverj··on Riot Games: Peeking into Valorant's Netcode (2020)
at this time valve official servers were 64 tick and FACEIT 128 tick.

This has been replaced by 'subtick' which I don't know enough about to comment.

coverj··on Ask HN: What is the most impactful thing you've built?
> I'd like to make an SQL-oriented library so people don't have to settle for JPQL/Hibernate--started but not done/promoted.

I'm sure I'm asking this on behalf of many people - any chance of a sneak preview?

coverj··on It’s painful how hellbent Mark Zuckerberg is on convincing us that VR is a thing
Just in the interest of balance I am very happy with Starlink, I usually range between 90-120Mbps and 30-60ms latency. It can be a little patchy to play latency sensitive games on (guessing these are the sub seconds timeouts you mention), I swap to tethering my phone for that but day to day (zoom meetings, etc) I have found starlink to be a massive upgrade on the alternatives available in Australia. In 12~ months as a customer I think I've tethered my phone for a zoom call once.
coverj··on Show HN: I finished v5 of a JVM framework I've spent spent half a decade making
I have a few questions about this approach, cards on the table I mainly deal in C# where DI (through the framework) is the default. How do you manage the initialization of all of the dependencies? Do you need some sort of "root" where everything is initialized and passed in? That was all I could come up with while keeping it testable and that doesn't sound maintainable once you build up the number of dependencies.
coverj··on The State of Web Scraping 2022
I have been interested in web scraping lately but never really dived too deep. Did anyone have more indepth resources (github projects, blogs, forums, etc) than the tutorials that are basically install beautiful soup and get data from a tag?
coverj··on Nomad vs. Kubernetes
DigitalOcean and Linode that I'm aware of, may be others
coverj··on For soccer players, the less brain they use, the better for penalty kicks
I have often thought about this, especially in penalty shoot outs where there are 4 people who aren't the "best" penalty taker that have to take one.

As has been mentioned there are penalties that are just unsaveable and against an elite penalty taker maybe a goalie is better off just picking a side and taking a chance against them but against the rest of the takers I'd be thinking eliminate the chance they get a freebie by diving too early or just picking a side and force them to score the hardest penalty possible

coverj··on Fable 3: F# to JavaScript compiler
Bought the book as well and would recommend it. Also have a look at Scott's talks (links are on the website or search his name in youtube)
coverj··on GM, Ford knew about climate change 50 years ago
the ideas aren't bad though, you just don't agree with them. Banning meat isn't something I would get on board with but it would probably be effective. There's been a lot of discussion lately on HN about nuclear and I can actually see both sides of the debate. Plastic straws I think you have actually just strawmanned environmentalists here as I've never seen plastic straws mentioned as a solution or contributor to global warming.
coverj··on Microsoft just force restarted my Windows PC again to install more unwanted apps
> Why do people still use Microsoft(MS)?

for me, Steam for video games and Visual Studio

coverj··on # of days since the last alg=none JWT vulnerability
The way I've seen it work is with having short lived access tokens and a refresh token, with the refresh token being saved to a database so it can be revoked. I think the benefit over an opaque token is that you have data that can be verified to be true and then passed on to multiple places. E.g passed between microservices
coverj··on Australia fast-tracks plan to send solar power to Singapore
thank you for the explanation!
coverj··on Australia fast-tracks plan to send solar power to Singapore
sorry, could you dumb this down a little? how does this affect the price/GW? (I'm not questioning it does, I'm saying I don't understand the rest of what you said)
coverj··on Ask HN: What do you use for app authentication?
Some options include - Ory Kratos/Hydra - Keycloak - Identity Server
coverj··on Questions to ask before adopting microservices
I'm only probably a month ahead of you but with my research and initial testing I've liked https://stoplight.io/open-source/prism/ so far. There are a lot of other options out there too if you are willing to make a swagger/open api spec
coverj··on Show HN: Ryeboard – Visual Workspace
event storming was exactly what came to my mind as well. Seems like an impressive product, well done
