matthews3··on Instrument clusters are now paid extras in two Hyundai models
A lot of Minis had the central speedo. Unsure if it's true or just automotive legend, but allegedly it was for cost cutting (fewer changes between left hand drive and right hand drive models). So nothing ever changes.
matthews3··on Show HN: Pi-Black – Use Your Claude Max (Or Pro) Subscription with Pi
Does the system prompt and list of tools give away that you are not using Claude Code?
matthews3··on Confdiff – semantic diff for config files (JSON/YAML/TOML) that redacts secrets
> Which keys count as secret is decided by built-in heuristics on the key name

Maybe you could automatically redact high-entropy strings? It might be more reliable than looking at key names.

Do I look like I know what a JPEG is? I just want a picture of a hotdog.

I hate it when I have to think for myself.

Is 2008 a good cut-off? My 2016 BMW doesn't really have any annoying electronics or nannies compared to my 2005 model (other than electronic power steering :))

I live a 5 hour train ride from London and my mobile data is also unusable.

Fans can move a lot more air than convection.
matthews3··on Samsung's 60% DRAM price hike signals a new phase of global memory tightening
At the silicon level, it is the same.

Each memory DIMM/stick is made up of multiple DRAM chip. ECC DIMMs have an extra chip for storing the error correcting parity data.

The bottleneck is with the chips and not the DIMMs. Chip fabs are expensive and time consuming, while making PCBs and placing components down onto them is much easier to get into.

matthews3··on Google is killing the open web, part 2

matthews3··on Google is killing the open web, part 2
Could you run XSLT as part of your build process, and serve the generated HTML?
matthews3··on Hyundai Paywalls Brake Pads replacement on Ioniq 5 N
I think for AGM batteries, it uses different charging curves depending on the age/health of the battery.
matthews3··on Nvidia is gearing up to sell servers instead of just GPUs and components
A 300mm wafer on a recent process node (TSMC N3) is estimated to be around $20k at quantity[1]. I don't know what kind of testing and crazy packaging processes would cost for a wafer-scale chip, but I can't imagine it would put the price anywhere near the millions.

The readme is very overwhelming but still doesn't tell me anything about the language, and the only file in the example directory is a hello world.

It might be good to expand on that, for those of us that don't remember the original W++ :)

matthews3··on Reverse Engineering a 1979 Camera's Spec
> Seems like I loaded the film incorrectly and nothing was on them, so I hate my life right now. Let’s skip this part then.

That's a shame! It's a mistake almost everyone that has used a film camera has made, though.

On these older SLRs, one thing you can do to check that the film is loaded properly is to watch the rewind crank as you advance to the next frame. If everything is loaded and the film is engaged properly, you should see it turn.

> Boom. Subscription gone. Access revoked. Business workflows broken.

Maybe we need more regulation to require a grace period after a failed payment...

matthews3··on The value of bringing a telephoto lens
> Normally they only use primes to achieve compact setup

There are the two Tri-Elmar-M lenses (16-18-21, and 28-35-50) which select between discrete focal lengths instead of zooming continuously :-)

matthews3··on Setting serial baud rate on ESP-IDF does nothing
The baud rate is just sent to the USB device, so that if you were making a real USB-serial adapter, you'd know how fast to go :)
