wrenky··on We Are Forking dotenvy into dotenv-ng
direnv + nix flakes solved so many problems for me, I have no idea how other people work on multiple projects at the same time without getting mixed up.
wrenky··on AI is a bad tool
I personally love coding! unfortunately for me the agents are much faster at it and often more correct, especially after iteration. Guiding AI is more efficient currently.
wrenky··on Satya Nadella: "We need to find something useful for AI"
Totally anecdotal, but recently my wife had to go to urgent care for something wrong with her ankle- They send a 4-5 page sheet of arcane terms and diagnoses to her care app (relayed to me via text) and I just slammed that into gemnai and asked "what does this mean" and it did quite well! Gave possible causes, what it meant for her in the long term vs short term, and ways to prevent it. I had a better understanding of what was wrong before the doctor even got to my wife in the waiting room!

Obviously still double check things, but it was moment of clarity I hadn't really had before this. Still needed the doctor and all the experience to diagnose and fix things, but relaying that info back to me is something doctors are only okay at. Try it out! take a summary sheet of a recent visit or incident and feed it in.

wrenky··on The secret medieval tunnels that we still don't understand
The problem there is why they have such tight bottlenecks periodically- Why not just have a traditional cellar?
wrenky··on An Honest Review of Go (2025)
They are an improvement over most languages, but the are _not_ better than sum types for the reasons listed above. Way less flexible and forces a lot more verbosity when compared to more functional languages.

Hes definitely wrong on how the error types can help account for that but it would be best in class if we could properly chain them AND use all the greatness from interfaces.

wrenky··on You Need to Ditch VS Code
There is a good argument for never using debuggers except for core development- Once finished your logs/metrics/events should be good enough to understand what is happening in an application. If debugging your application requires breakpoints you wont really be able to debug a live instance, and wont be able to easily signal off what is happening in the future.
wrenky··on Why I love OCaml (2023)
> Our hope is that these extensions can over time be contributed to upstream OCaml.

Yeah, its more just extensions to support their use cases at scale. Think of it more as bleeding edge ocmal, once they work out kinks/concerns they'll get merged back into the language OR if it remains ultra specific it'll stay in oxcaml.

Not a complete own version lol

wrenky··on Steam Networks
I thought that too (but more New York Christmas Eve movie impressions) until I saw steam coming from manholes in Denver. Blew my mind that it was a real thing haha.

In addition to the heating/cooling uses, the mint in Denver uses it to clean coins!

wrenky··on Researchers created an open rival to OpenAI's o1 'reasoning' model for under $50
nope you have the article right. "if you copy an existing model, you can get a pretty comparable model!"

Really, [what the underlying paper](https://arxiv.org/abs/2501.19393) shows is how much you can improve existing models with several of the techniques released by openai recently (extending thought processes via "wait")

It shows we can get a lot of mileage out of that technique.

wrenky··on Whats your max wpm in typing?
Surprisingly I find it does! The bulk of the time shouldn't be spent typing I agree, but often once I've mapped out what I want to do I need to type a lot. Improving my typing helped my "flow" as I made less mistakes and was generally faster once I got to the "make it happen" stage.
wrenky··on Why is homeschooling becoming fashionable?
I was homeschooled from 2nd - 8th grade. My elementary school was trying to put my brother on adderall and my class had sorted me into the "blue" group of readers (colors of the rainbow for reading ability). I apparently came home talking about how I was slow and it was okay because we all learn at our own pace.

Definitely not a great school! both my brother and I ended up going to college and getting engineering degrees, and had zero issues with academics in high school. My mom did a pretty okay job but it was absolute hell on her, I entered high school ahead on mathematics/history but pretty behind on writing and science. The science I dont blame my mom for, all the curriculum at the time was insanely religious, so the ones we could find were very dry.

wrenky··on Why is homeschooling becoming fashionable?
Those are sources, and while curiosity is great most kids are focused on specific things not everything. Kids need direction and somebody them to focus on things they dont want to learn- like a kid who loves animals isnt going to learn math or how to write well, and a kid whos interested in history might not care at all about science.

Parents are no better at this unless they are incredible focused on utilizing a curriculum and addressing their own issues along the way- And even then, learning with other kids is incredibly helpful. Talking to a computer is not a replacement for a teacher (yet).

wrenky··on Ask HN: Is maintaining a personal blog still worth it?
> I don’t think I understand a subject unless I can teach it, explain it and argue both sides about why you should and shouldn’t use it.

this is 100% why I write "courses" alongside my notes when learning something- forces you to think about pitfalls you fall into while learning, things you need to revisit and an overall story on how to introduce a topic.

but blogging? Outside of an immediate personal sphere I don't really see the need. Although that said I'm looking at things like [pico.sh](https://pico.sh/prose) just to play around with presentable notes/courses rather than my default obsidian stuff.

wrenky··on Functional Programming Self-Affirmations
One thing this article does is assume extreme functional mindset, I dont even think OOP enters into the authors mind- With that context, I think that statement isn't about object constructors but type constructors.
wrenky··on Rust for the small things? but what about Python?
Man, I get that python is easy to write but maintaining deployed python code is some of the worst experiences in modern software devlopment.

Less Code != less buggy or more stable code, it just means more implicit code. I contend you spend way more time after release debugging runtime issues or patching random edge cases that are just completely eliminated in typed languages, or deploy/env issues that are eliminated in languages that produce a single binary.

Developer efficiency should include your support time after the writing code.

wrenky··on Rust for the small things? but what about Python?
AND holy shit I have to install another venv to run special-snowflake-3 script I will literally lose it. I literally have a folder of all the venvs I need to run one-off shit people pass me. I get the lack of wanting to compile things but thats not a problem with modern build systems like Rust/Go have- Beyond trivial.
wrenky··on Chicago Fed President Goolsbee says if economy deteriorates, Fed will 'fix it'
The Fed will always fix it as _thats what the fed does_. Debt, spending, interest payments are all treasury- The stability of the system is the fed. They often work together but I'm willing to bet the fed is very unhappy with the level of debt and unable to do anything about it. Fed just controls the money supply and interest rates in an extremely technocratic way, divorced from the government or policy making.

> Cumulative inflation of 66.3% over the last 20 years (based on CPI, it's probably actually worse).

While this is bad, if you check the cumulative inflation from 1999-2019 where inflation had essentially been "missing" in the 1-2% range the cumulative inflation is 55%. Regardless though looking at inflation numbers is only half the picture, if you look wage growth in the same period, comes out to several percentage points above inflation/price growth. Even with all the big numbers we are doing pretty well!

wrenky··on Go east from Seattle
Its the moderating effect of the Mediterranean! Its wild to see the temperature differences of Wisconsin, Montana, Dakota(s) compared to France & Spain. All that water helps insulate Europe even those its at a northern latitude.
wrenky··on California could ban Clear, which lets travelers skip TSA lines
Man, unless its dramatically improved in the last 5 years Sydney and Melbourne were around the same level as hell as LAX/SFO are. Sydney was particularly bad the 3 times I had to move through it haha. My average LAX traversal is much smoother than Sydney ever was.
wrenky··on USAF Test Pilot School, DARPA announce aerospace machine learning breakthrough
Seriously, that line strikes fear into my heart and I only handle rest APIs not billion dollar airplanes with actual people in them.
wrenky··on Discord is laying off 17 percent of employees
I think the growth of Discord partially explains it- They needed a _lot_ more SRE/Scale engineers, which causes growth in HR/Management layers.

They also added a bunch of monetization stuff (discord nitro) and attempted to get more "community" based features like custom emotes/badges/profiles per server/watch party stuff.

The core experience is the same, I think they've done a great job ensuring that doesnt change! They have also done the usual software stuff, improving core outskirts like stability/performance/login methods/slash options. Its the same core product but better.

wrenky··on Canonical to Work on Improving Snap Support Across Linux DIstributions
nope, that's essentially the problem. Snap is curated and controlled by Canonical and they are forcing the issue.

The issues that both share are slow starts, larger package sizes, lack of safe ways to interact with the rest of the OS, etc.

Base concept is actually really good- Separating out dependencies and "containerizing/sandboxing" userspace applications is just a no brainier from a security and maintenance point of view. Its so nice to be able to easily install several versions side by side and know you arent fucking up system dependencies. Once they (flatpack, snap, some future competitor/iteration) iron out the kinks it'll 100% be the way systems are managed.

wrenky··on Nue.js: Rethinking Reactivity
I think its kinda great its on the front page, I only work in backend so this looks quite appealing like ALL tech demos do. Love to see it pulled apart in comments with explanations I understand haha
wrenky··on Dear Ubuntu
"championing" it? probably not, but I'm a huge fan of the goal. Flatpack/Snap both try to take an application and isolate it from the system. Its like docker but for userspace application rather than services. Package managers like apt/yum modify the system at a root level, a bad package here (or a bad library) can cause problems if its a mistake, or compromise if malicious. You should only use them for stuff that needs root hardware access or root permissions at some point- everything else should be sandboxed and isolated from that critical portion of your system.

[Shutteworth makes a pretty good argument for snap](https://www.youtube.com/watch?v=0z3yusiCOCk) (and by proxy, flatpack) and the why we need virtual machines/docker/LXD/(snap/flatpack)/package managers.

So I wouldn't say I'm championing snap, but I do believe the concept should be used everywhere. Flatpack? snap? Something new? Dont really care, I just want the containerization benefits at the userspace level.

wrenky··on Ask HN: Engineering managers, how do you onboard new hires?
lmao right? My new hires spent the first week in corporate/domain training, then a few days getting situated, setup and stuff. Probably 2 weeks before I "expect" a PR but even then the first few tasks are a gentle introduction.
wrenky··on LMDB: The first version of Redis, written in Tcl (2009)
I use Tcl daily for work and personally love it! Its syntax is weird but when it clicks things just make sense in a zen way. Much like getting into the groove in lisp or something, it _feels_ correct in that minute.

The main problem is just tooling. There are some insanely cool language features like Expect (still the best implementation) or starpacks/starkits, yet there is no basic package manager. You are stuck installing via yum/apt or building from source if you are lucky to find what you need. Most of the time you can just assume there isn't something you can rely on, and you'll have to patch source tcllib (the batteries included library).

wrenky··on Tipping at self-checkout has customers crying ‘emotional blackmail’
Customers dont have to guess, just pay the 15% and leave. Thats just the standard.

If a company chooses to pay more, their prices go up and they cant compete. Even though its just shifting the cost from a hidden to a declared one, its enough where restaurants struggle and either abandon the model or go out of business. Its an industry problem that needs to be fixed at that level, you cant just say "Go out of business, Done!" as thats not a realistic solution.

wrenky··on Tipping at self-checkout has customers crying ‘emotional blackmail’
Its not that employers are cheating them- Thats the job and what it pays. Most waiters/waitresses are payed below minimum wage and make up the difference with tips. Its something like $3/hr on average, its even accounted for in the tax code.

Is this your fault that the industry as a whole legally shifts that responsibility onto the consumer? Definitely not! Does that make a person an asshole for knowingly paying less? Yes.

wrenky··on Htmx Is the Future
> , it's because all the devs writing shitty MPAs are now writing shitty SPAs. If this becomes popular, they will start writing shitty MPAs again

It brings a tear of joy to my eye honestly. The circle of life continues, and people always forget people are bad at programming (myself included).

wrenky··on Apple’s agreement with Cupertino
Not quite- Sales tax from sales by customers in California is being located to Cupertino. So if a customer in Fresno bought an iphone, that tax is allocated to Cupertino. Other states assess tax differently.

After that fresno customer buys an iphone and pays the tax to Cupertino, Cupertino gives apple 35% of that tax back effectively lowering their sales tax rate.
