fix4fun··on Everything old is new again: memory optimization
Digression: Nowadays when RAM is expensive good old zram is gaining popularity ;) Try to check on trends.google.com . Since 2025-09 search for it doubled ;)
fix4fun··on Nmap in the movies (2008)
It's a beautiful idea :D

Imagine then, after many years during some awards: and the best support role goes to ... NMAP :D

fix4fun··on Qatar helium shutdown puts chip supply chain on a two-week clock
Good to find another fan of asianometry channel ;)

I agree, this story above would be a perfect for another asianometry document.

fix4fun··on Mouser: An open source alternative to Logi-Plus mouse software
Nice project. Respect :)

I worry only how long it will be supported? I hope there will be small community maintaining it ;)

Once again nice project and good luck.

fix4fun··on I Found 39 Algolia Admin Keys Exposed Across Open Source Documentation Sites
Interesting how many people already are playing with these API keys ? ;)
fix4fun··on Willingness to look stupid
Fear of failure is a stumbling block for science.

That's why many universities declare in their charter that research doesn't have to be practical. The practicality of RSA asymmetric encryption only became practical with the advent of the internet ;)

fix4fun··on New accounts on HN more likely to use em-dashes
Thank you marginalia_nu for article and this comment (word stats).

I got similar feeling. I'm new here, but got a feeling that some comments are like bot generated.

Such low p-values are proof that something is going on.

Hipotesis (after your recent word statistics): that some bots are "bumping up" AI related subjects. Maybe some companies using LLM tools want to promote some their products ;)

marginalia_nu respect for your work :)

fix4fun··on Man accidentally gains control of 7k robot vacuums
My first think after reading title was "Silicon Valley" series (2014) and episode with Gilfoyle and taking control of smart fridges ;) Sorry. A but out of topic, but I had to mention ;)
fix4fun··on Pebble Production: February Update
Thank you for checking :) I was unable to find any details about it. 30 days are impressive, so I was curious if there is some special battery in Time 2.
fix4fun··on Pebble Production: February Update
Any specs about Pebble 2 battery capacity ?
fix4fun··on Show HN: Micasa – track your house from the terminal
I think the same. Why overcomplicate and just use some online Spreadsheet like from Google Docs. The same or even less effort.
fix4fun··on Four Column ASCII (2017)
Yes, that's true ASR-33 was first application, but IBM has impact on ANSI/ASA comeete and ASCII standardisation. In 1963 IBM System/360 was using BCD with digits quick "parse" and in it's peripherals. I remember it from some interview with old IBM tech employee ;)
fix4fun··on Four Column ASCII (2017)
For me was interesting that all digits in ASCII starts with 0x3, eg. 0x30 - 0, 0x31 - 1, ..., 0x39 - 9. I thought it was accidental, but in real it was intended. This was giving possibility to build simple counting/accounting machines with minimal circuit logic with BCD (Binary Coded Decimals). That was wow for me ;)
fix4fun··on Custom Firmware for the MZ-RH1 – Ready for Testing
Really nice project – respect :) Finding that boot ROM mode by bridging GPIO lines is a great catch. Having a hardwired 'safety net' makes custom firmware projects much more viable. When you were testing the flasher, did you find the CXD2687's flash interface to be deterministic in its failure modes, or did you run into any race conditions/timing issues during the erase/write cycles?
fix4fun··on The Architecture of Open Source Applications (Volume 1) Berkeley DB
I got similar experience. Using Berkeley DB until I found SQLite ;) Of course it is not directly key/value, but small size, simplicity and IO performance was amazing for me.
fix4fun··on SectorC: A C Compiler in 512 bytes (2023)
I think the same. Really nice project and good trick with hashing tokens.

PS. There left 21 bytes (21 * 0x00 - from 0x01e0 to 0x01fd). Maybe something can be packed there ;)

fix4fun··on Unlocking high-performance PostgreSQL with key memory optimizations
Nice tool. Do you know maybe similar tool for MySQL ?
fix4fun··on My AI Adoption Journey
Thanks for sharing your experiences :)

You mentioned "harness engineering". How do you approach building "actual programmed tools" (like screenshot scripts) specifically for an LLM's consumption rather than a human's? Are there specific output formats or constraints you’ve found most effective?

fix4fun··on GB Renewables Map
Really nice project :)
fix4fun··on A Broken Heart
`git bisect` is interesting option. I haven't heard about it before. Thanks for info. Still learning something ;)

I'm old school. I used to do "manual bisection" on git history by just `git checkout <commit_id>` until I find first introducing bug commit.

Then another "bisection" on commit changes until minimal change found.

Deterministic bugs are quite "fine". For me personally worst are randomly occurring bugs in specific conditions for eg. some race conditions.

fix4fun··on Tractor
Thanks for info. And once again really nice project :)
fix4fun··on Tractor
Really nice project - respect :)

Got two questions: 1. How fast it can ride ? If I good estimate (based on max 2750 RPMs for electric motor MY1016 350W 36V, gear ratio ~100:1 and height of rear wheel ~0.5m) it should got about 0.8 m/sec. So really safe for kids and dad :)

2. How long does the battery last ?

fix4fun··on High-Altitude Adventure with a DIY Pico Balloon
Yep, cost effectiveness of project is amazing & really nice application for WSPR. WSPRnet for checking readings seems to be still online https://www.wsprnet.org/drupal/wsprnet/map .
fix4fun··on The fax numbers of the beast, and other mathematical sports
667 - “fax number of the beast” - that was funny ;) The thing about mathematics is that it can tickle your brain - in a creative way.

It's becoming increasingly difficult these days, with so many things competing for your attention and "brain-deadening" you. It was a wonderful thing to be bored and play around with math. My favorite moments were the epiphany - that there is some hidden connection between math areas or something got new meaning.

fix4fun··on Lessons learned shipping 500 units of my first hardware product
50k lm is quite high. What electric power consumption does it have ? I estimate around 500 Watt, am I right ?
fix4fun··on Show HN: Sandboxing untrusted code using WebAssembly
yep, more examples with agents use will be helpful
fix4fun··on Bunny Database
Yes, libSQL would fit better in that case. But all of it is marketing for better audience ;) (SQLite got x69 more searches than libSQL in Google).
fix4fun··on What's up with all those equals signs anyway?
My fist association was brainf..k (*.bf) programming language
fix4fun··on What's up with all those equals signs anyway?
That was nice part of 1990s - many systems allow for funny things ;)
fix4fun··on Coding assistants are solving the wrong problem
Yes, that's true, because as developer you have to check if "generated" code meet your standards and if is handling all edge cases you see.

When you are an experienced developer and you "struggle" writing manually some code this is important warning indicator about project architecture - that something is wrong in it.

For such cases I like to step back and think about redesign/refactor. When coding goes smoothly, some "unpredicted" customer changes can be added easly into project then it is the best indicator that architecture is fine.

That's my humble human opinion ;)
