evnix··on Anecdotally, programmers dislike "reduce"
The name itself is confusing to begin with.

I come across reduce once in a few months, then I think it's a neat trick and a nice to have function.

then I forget it's even available and don't ever use unless these days LLM brings it up again.

evnix··on What happens when an LLM never sees material beyond fifth grade?
Feels exactly the way my 2 year old behaves.

How does a fan work: Swish swish swish swish

Where do these clouds come from: Points to a far away direction in the sky and says they come from there.

Who does all these roads, trees and environment belong to? It all belongs to me. Obviously.

They have an answer ready for every question you throw at them and they will answer it with absolute certainty. I will have to wait and see at what age does the concept of "I don't know" develop.

evnix··on Gemini CLI will stop working from June 18, 2026
Would be very difficult keeping it going knowing you will be laid off.
evnix··on Ask HN: We just had an actual UUID v4 collision...
All the probability mathematics aside, the real world we live in is probably a lot less random even with the best hardware random number generators.

I've moved on to something like TSID(where security isn't a factor) or uuidv7 to make sure this never really occurs in practice rather than over engineering the code with retries.

evnix··on All elementary functions from a single binary operator
Can someone explain how is this different from lambda calculus, it seems like you can derive the same in both. I don't understand both well enough and hence the question.
evnix··on Running NanoClaw in a Docker Shell Sandbox
This is similar to how I solved a BYOK(bring your own key) feature at work. We had a lot of hardcoded endpoints and structures on the client and code that was too difficult to move over a nice BYOK structure within the given timeframe. So we ended up making a proxy that basically injected customer keys as they passed through our servers. note that there are a lot security implications doing this.
evnix··on Build a Compiler in Five Projects
Most of these compiler projects and books would be 100x more popular and accessible if they were in Javascript
evnix··on How does gradient descent work?
Can someone please ELI5
evnix··on Traefik's 10-year anniversary
Letsencrypt Https should be a default like caddy.

Mounting certs, opening right ports and mapping them right is really not what I want to mess around with just to get SSL.

evnix··on Designing NotebookLM
NotebookLM is a success in spite of the interface not because of it.

Pretty awful UX to be honest. Credit goes to the backend engineers who made this happen.

Took me ages to figure out you can copy paste simple text. Editing any text isn't great either.

Why isn't there a dedicated markdown notes section with folder and files? Most of us won't have ready to use PDFs but almost all of know how to use a text editor and paste text into it. Your Notes app UI is without proper support for editing and maintaining notes.

evnix··on How to Stop Your Event-Driven Architecture from Turning into Chaos
Are you a middle aged+ developer? You read the DDD/CQRS/event driven book or viewed the conference. My dear friend, you have fallen victim to developer porn. It's very addictive. You end up playing "the architecture game" rather than building anything useful.

I have yet to come across ONE good large scale project that makes use of these and isn't a big ball of mud.

evnix··on My Self-Hosting Setup
I wish I had the time to do any of this. I could probably do it on a weekend but maintaining it, upgrading it to keep up with new releases would be something I wouldn't have time for.

I end up just paying a cloud provider and forget about it.

Anyone else on the same boat? What has been your approach?

evnix··on Postgres LISTEN/NOTIFY does not scale
After working with NATS, I wouldn't want to touch Kafka even with a long stick. Its just too complex and a memory hog for no good reason. It doesn't have all the features that NATS supports as well.
evnix··on Ask HN: Cursor or Windsurf?
Apart from the GUI, What does it improve on when compared to aider.
evnix··on Ask HN: Cursor or Windsurf?
How does this compare to aider?
evnix··on Fintech founder charged with fraud; AI app found to be humans in the Philippines
I get that the intention was not harmful, but i am trying to make the poster understand how people might feel.

Regarding Germans, if the news was, "AG deportation private company is a scam, they were sending people to forced euthanasia"

and someone came and said, "AG stands for Actually Germans". I am sure no German would want to be associated with that.

evnix··on Fintech founder charged with fraud; AI app found to be humans in the Philippines
Not racist but offensive indeed. It's like relating school shootings to white people. A white child sitting in Norway might not relate and may find it offensive and insulting.
evnix··on Marrying Up and Marrying Down
Education is just a proxy for wealth, just like extravagant vacation pictures on Instagram and nice cars.

Six figure salary seems "meh" when compared to Instagram which keeps showing women 3 figure millionaires and their daily routines in their mansions.

I don't like any of this, but that's how humans are and that's the world we live in.

evnix··on Why it's so hard to build a jet engine
I feel, What's more harder are the jet engines on fighter planes. These are usually a decade or two ahead in terms of advancements. The technology here trickles down to commercial jet engines slowly. Things like Metullargy for blades etc are a closely guarded secret. China and India are pouring billions into research just to get theirs close to even the lower end of what GE has to offer.
evnix··on Keeping a Changelog at Work (2020)
Any kind of work, most sprint reviews are basically: what can we do better so that we can squeeze more out of you than last sprint.
evnix··on How we centralized and structured error handling in Golang
This is the way to go, pretty much solves, 404 resource not found or route not found. But you will get laughed at by so called architectural dogmatists. Remember we aren't really doing REST, it's just RPC and let's call it that.

Shoehorning http protocols error codes as application error codes, drinking the cool aid and calling it best practice is beyond bizzare.

evnix··on 7 Databases in 7 Weeks for 2025
Whenever I see a DB written Java, I run, very fast and very far away.

I've never had good experience with these implementations. If you say, the DB isn't performing well, the only answer you get is, well you forgot to tune these 1000 knobs and good luck if your data doesn't fit in RAM.

For some reason I feel your DB in a text file, would fare just as good as these given the same memory and resources that these Apache/java DB servers demand.

evnix··on Please stop the coding challenges
As someone who interviews i support these tests, my reasoning is very different

1. Applicants getting hired because the manager and the candidate is from the same institute or they like the same team or band.

2. Bias based on age or race. I try to remove my own sub conscious bias as best as I can but most don't.

3. HR thinking you are not good enough and rejecting because you did java 18 and not java 19. Or you can write impressive React but haven't done Vue.

It takes the managers and HR a little out of the equation. They just rubber stamp your decision.

Take home exercises are something we tried but the incidents of cheating were so high and good code is so subjective that we gave up.

evnix··on Self-Contained Executable Programs with Deno Compile
Small binary size?

58MB for a hello world doesn't not seem small to me.

58MB might not seem much but we used to have entire games in a few MB.

You might argue it doesn't increase that much after 58MB, I don't know what is this good for. I want my command line apps to be lean, I don't care about decoupling source and deno binary on a server side program. I don't see the benefits personally.

evnix··on We're (Finally) Going to the Cloud
I wish someone marked it as duplicate or too broad or too specific and closed it.
evnix··on On Building Git for Lawyers
You make a good point,

Although the country where I am in doesn't restrict me from vaccinating my pet by myself, I'd rather just outsource it to a vet. vet clinics here also have added facilities like pet cleaning etc which is a plus . In this case I find I'd rather enjoy my pet than figure out its innards or it's anatomy.

evnix··on How Google Maps fixed India's street name problem [video]
They have street names, but the areas are quite massive so you would have street names that would repeat and the areas are in constant development and more streets and flyovers gets added or removed every 2-3 years.

Address in India follows a block approach and the address is usually longer than a comparable western address, example;

B1803 xyz apartment

Sub block name

Block name

City division name

City name with pincode

State name

B108 stands for B wing 18th floor and house 3 in that floor in an apartment complex named xyz.

Street names don't scale well when you have a billion people with lot of vertical buildings in places like India or china.

evnix··on Launch HN: Codebuff (YC F24) – CLI tool that writes code for you
I think Aider does this to save tokens/money. It supports a lot of models so you can have Claude as your architect and another cheap model that does the coding.
evnix··on Show HN: Algorithm to Predict Romance/Indian Languages from Latin/Sanskrit
Some Languages like konkani are more closer to rig vedic in respect to both features and words, and have very little classical Sanskrit as borrowed vocabulary.

evnix··on What's worse than an N+1: Accidental Cartesian Products
true, from what I've seen, people use it for convinience, ORMs do always have an escape hatch to use raw SQL, and some do allow mapping raw SQL to objects.
