jcarrano··on Thomann takes legal action against Fender
If signals were based on low impedance current loops as opposed to voltage-based like they are today, interference could be much reduced. This would break phantom power, so power to preamps would have to be send through another set of conductors, which would make the design of the electronics easier as well as safer.

Of course, none of this will ever happen.

jcarrano··on Notepad++ Zero-Click RCE via Path Traversal (CVE-2026-52884)
Steps to reproduce:

1. Get pwned

2. Open Notepad++

3. Get pwned again (?)

jcarrano··on Notepad++ Zero-Click RCE via Path Traversal (CVE-2026-52884)
We are living through CVE-inflation (or CVEflation?) where anyone who discovers a bug using LLMs will instantly claim it is huge security hole.
jcarrano··on Notepad++ Zero-Click RCE via Path Traversal (CVE-2026-52884)
How is this supposed to be zero-click? All attack scenarios require either the attacker to modify configuration files, or the user to click on a malicious shortcut.
jcarrano··on The Skeuomorphism Nobody Talks About [video]
Optically, it looks very nice, but it kills my CPU.
jcarrano··on All the bugs they found
I found, in my rather recent experience with Go, that using anything other than zero for invalid, default or "sentinel" values is a source of potential problems due to the lack of real constructors.
jcarrano··on The weird, wild story of humanity's obsession with gold
It is also relatively easy to work, since ancient times. Iridium is the rarest metal, so rare and hard to work that it is not practical.
jcarrano··on Why is almost everyone right-handed? A new study connects it to bipedalism
At one point I used to have two mice plugged in and would use either one depending on which hand was free.
jcarrano··on Appearing productive in the workplace
That's honestly a fear of mine, that I might lose the taste for simplicity.
jcarrano··on Gap between national food production and food-based dietary guidance (2025)
How much of the fish self-sufficiency of China is due to them plundering the seas across the globe?
jcarrano··on Tell HN: Litellm 1.82.7 and 1.82.8 on PyPI are compromised
Thinking how a secure setup for uploading packages from a CI would look like: the package must be signed by the devs, and for that they must build it independently on their machines (this requires a reproducible build).
jcarrano··on Afroman found not liable in defamation case
100% of those cases would be favorable to cops. Defamation laws are quite restrictive in Europe, much more so when it involves public officials (take a look at the Strafgesetzbuch)
jcarrano··on Afroman found not liable in defamation case
Exactly what I meant. For example, in Germany one would have a hard time for much less.
jcarrano··on Honda is killing its EVs
"Download more HP" is the new "download more RAM".
jcarrano··on Lenovo’s new ThinkPads score 10/10 for repairability
My colleague's Thinkpad had its fan fail. He ordered a replacement which arrived next day. He swapped it himself and kept on working.
jcarrano··on British Columbia is permanently adopting daylight time
100% agree. I used to watch the sun rise over the river from the train during my commute. It was worth having to wake up when it was still dark.
jcarrano··on Microwave Oven Failure: Spontaneously turned on by its LED display (2024)
> This control board uses the same microcontroller GPIO pin to both drive segment A of the LED display and sense the door switch.

Is it necessary to be so skimpy with a safety feature?

jcarrano··on Ireland rolls out basic income scheme for artists
"If you need subsidies in order to live off art, you don't live off art but live off the state".

As part time artist I see many problems with these schemes:

- Decoupled from people's actual appreciation of the art being done: I feel better when I know people voluntarily gave up their hard-earned money for what I do. - Monopoly-style "winner takes all". The people who benefit from this are the ones already in a position to ask for the benefit. - No one bites the hand that feeds then. That will form a body of "artists" subservient to the state.

The human problem is that no artist is willing to acknowledge that the public is not willing to spend money on their product.

> Society has not disintegrated.

Has art improved in any measure?

jcarrano··on Linux From Scratch ends SysVinit support
That is one of my problems with systemd: it has way to much "magic" built in. SysVinit/OpenRC and related are easy to understand and debug: they only do what's in the scripts.
jcarrano··on Vibe coding kills open source
The 3d-printer of software: get a custom part quickly and cheaply, even if not suitable for mass production.
jcarrano··on Judge hints Vizio TV buyers may have rights to source code licensed under GPL
They "conveyed" the software, according to GPL wording. They violation is towards the original software's authors.
jcarrano··on Basalt Woven Textile
"Long asbestos fibers have been shown to interfere physically with the mitotic spindle and cause chromosomal damage"

jcarrano··on Git 3.0 will use main as the default branch
With master gone, it's time to get rid of the man-pages, which were invented to mansplain commands by bearded men in the 70s.
jcarrano··on Basalt Woven Textile
The problem with asbestos is that, due to its structure, it keeps breaking in the longitudinal direction, making thinner and thinner until it is the size of chromosomes. Physical interference with DNA is how it causes cancer.

My understanding is that basalt fibers seem to be glassy, not crystalline, so the breaking does not happen.

jcarrano··on The inconceivable types of Rust: How to make self-borrows safe (2024)
Having a separation between the "pure language" and the library is a requirement if you want to have a language that can be used for low-level components, like kernels or bare-bones software.

I don't think this is possible in a language that needs a runtime, like Go.

jcarrano··on Using street lamps as EV chargers
That was the first product released >10 years ago at my previous job [1]. The idea did not quite catch on, though, and the product was repurposed (successfully) as an OEM charger. There is not a lot of power available on street lamps and charging at 3.6kW is kind of slow. Consider that with almost the same hardware (especially the same expensive parts) and three-phase current, 22kW are possible.

It might turn out differently in the US, but it is hardly a new idea.

jcarrano··on DEC64: Decimal Floating Point (2020)
No point whatsoever. If you have to deal with money you never use floating point. Either use arbitrary precision, or integers with a sufficiently small base like blockchains do (which can be also though of as fixed point). Also you would never be multiplying two money value (there are no "square dollars").
jcarrano··on Installing and using HP-UX 9
I have the HP logic analyzer that runs HP-UX. To me it's crazy that I can connect to it with a 2025 Linux OS and run X11 apps remotely out of the box.
jcarrano··on Ask HN: What Are You Working On? (Nov 2025)
I canceled my Spotify subscription because it would not let me "reset" the algorithm to get fresh suggestions.

A "discovery algorithm" that I used (works great for jazz) consisted on looking up which musicians played on an album that I liked on discogs and searching for more albums from them.
