hackcasual··on M5Stack Launches PaperMono
When I order from m5, box is postmarked from California
hackcasual··on M5Stack Launches PaperMono
I have a tiny devboard collection habit, and gotta say coding agents work great with these. I've got a stick and a few dials running various hyper specific UIs for home assistant.
hackcasual··on Kuna: Decompiler Development in the Age of Coding Agents
I was working on adding better WASM support to ghidra, but now I can just point Claude to binaryen
hackcasual··on Leaked OpenAI financials show $38.5B loss and compute burn
It's wild to think how efficient Internet services were prior to AI. The most expensive thing would probably have been something like encoding video. Now you've a substantial portion of a rack dedicated to a user in the case of something like fable
hackcasual··on OCR for construction documents does not work, we fixed it
JBIG2 does glyph binning, as you say not exactly OCR, but similar. So chunks of the image that look sufficiently similar get replaced with a reference to a single instance.
hackcasual··on How I bypassed Amazon's Kindle web DRM
Interesting stuff. My first thought was "this is topaz" but if the font is bookerly, that makes less sense.

There's this old patent for earlier kindle web obfuscation, which used CSS layout to scramble text https://patents.google.com/patent/US8700991B1

hackcasual··on Walkie-Textie Wireless Communicator
Oooh, which one has a keyboard?
hackcasual··on Arm desktop: emulation
There's a handful of Windows game emulators taking off for Android. Using a modern snapdragon GPU, folks are playing Witcher 3, GTA 5. Some suffering gamer is playing through Dark Souls 2 using touch controls
hackcasual··on Anno 1800: Shadows of Beauty
Wait for a sale, they happen regularly and you'll want the DLC bundle
hackcasual··on Anno 1800: Shadows of Beauty
Just started playing the game a few weeks ago. It's very pretty.

From a game perspective it can seem pretty simplistic at first but there are a lot of interesting systems with hidden depth

hackcasual··on Nvidia bets on robotics to drive future growth
Last time I was in SF I took 3 waymo rides and attempted a fourth. The attempted one was cancelled after 15 minutes of waiting for it being 2 minutes away. As best as I can tell, the waymo was stuck at an intersection where power had been lost and didn't understand it needed to treat it like a 4 way stop.

2 rides went fine though neither was particularly challenging. The third though the car decided to head down a narrow side street where a pickup in front was partially blocking the road making a dropoff. There was enough space to just squeeze by and it was clear the truck expected the car to. A few cars turned in behind the waymo, effectively trapping it in as it didn't know how to proceed. The dropoff eventually completed and it was able to pull forward

hackcasual··on Maker Pipe – Structural Pipe Fittings for DIY Builders
Wild stuff. You can see the bottom horizontal trusses bending when loaded. EMT is just too thin walled for serious structural applications
hackcasual··on Maker Pipe – Structural Pipe Fittings for DIY Builders
EMT conduit isn't a great support material if you're handling human weight loads. The picture on the front page showing off the strength is visibly bending. It's kind of an awkward load profile, lower weight like an awning you're probably using ABS, higher weight you're using 1 1/4" system like steeltek or keeklamp

Petrol tax directly incentives fuel efficiency
hackcasual··on Thoughts on the Durov Arrest
Trying to understand his legal situation by analogizing with US law understanding strikes me as some real Dunning-Kruegering. Surely someone like Preston Byrne has someone he can reach out to to get a better understanding of the actual French legal situation Durov is in.
hackcasual··on Meshtastic's Opposition to Proposed Changes on 900 MHz Band
I've got a mix of LilyGo and Rak devices, and a sew Station G1's. LilyGo gets criticized, but after I switched to Rak antennas on them they work great.

The meshtastic discord definitely leans pepper as well. I live in a coastal urban area and the nodes here seem to be more general hobbyist.

I'm hoping to have some sort of automated BBS type node to play around with

hackcasual··on Meshtastic's Opposition to Proposed Changes on 900 MHz Band
Antenna selection is less important with LoRa than other mesh networks, which is nice meaning you can have a meshtastic watch for example.

The link budget is massive (150 dB) meaning getting a really nice antenna is less impactful than bumping your speed down a notch

Edit: LilyGo devices for 900MHz are notoriously terrible, and getting a $3 one will see a definite improvement

hackcasual··on Meshtastic's Opposition to Proposed Changes on 900 MHz Band
Been running a Meshtastic node for awhile now. Really amazing piece of kit. I regularly make 2 mile distant contacts in an urban area with an indoor antenna. Soon I hope to be able to have an exterior mounted one.

Hope they're able to protect their bandwidth

hackcasual··on Orca: WebAssembly Apps Without the Web
It's a 4 year old paper, and the biggest issue it brought up, malleable read-only data, is currently being addressed with the memory control proposal. The fact that a virtual environment can't prevent all types of erroneous program behavior is not particularly noteworthy. The fact of the matter, in particular when comparing WASM against containers, WASM is a generational step forward in terms of permissioning and isolation.

For my bonafides, this is me discussing this class of vulnerabilities 8 years ago: https://groups.google.com/g/emscripten-discuss/c/gGjklbJiX1c...

hackcasual··on Orca: WebAssembly Apps Without the Web
If you think using containers provides improved security over WASM I don't think you understood the paper. At no point did they demonstrate compromising the host of the WASM program, just corrupting the state of POC's. There are obviously risks associated with that, but nothing that improves by going with isolated/containerized native code.

Yes currently lacking ASLR and read-only memory sites increase some risks, but strongly typed function pointers, control flow restricted to function entry points and call stack isolation more than make up for it

hackcasual··on Show HN: Execute JavaScript in a WebAssembly QuickJS sandbox
IFrames are over-permissioned. For example an iFrame can exfiltrate data to a 3rd party

hackcasual··on Special-use domain 'home.arpa.' (2018)
There's a ton of gTLDs too, I just grabbed a cheap one and ACME-fied all my lan services
hackcasual··on Bento3D
Really nice workflow for a really common 3d print use case. I'd like to see the lid re-worked to print without support (the tall standing orientation is also asking for it to get knocked over). Not sure why they insist on 0.1mm layer height. That makes prints take forever.
hackcasual··on Espressif Acquires Majority Stake in M5Stack
Have half a dozen M5Stack based devices using ESPHome. There's a big community supporting that. When I tried developing using an IDE found them more troublesome.
hackcasual··on Meta Horizon OS
Modded beat saber is the only reason I still have kept my original quest
hackcasual··on Virtual Colossus
The biggest difference between enigma and Lorenz was Lorenz was broken without seeing a physical machine. It was broken as a very long message was transmitted twice with minor changes. That allowed recovery of of the plaintext and key stream
hackcasual··on Why AWS Supports Valkey
It's hard to quantify, but I think Amazon would have to be in the top contenders for most value gotten from open source software
hackcasual··on Show HN: filippo.io/mlkem768 – Post-Quantum Cryptography for the Go Ecosystem
It's also important to have an established history of use and vetting so by the time PQ is needed, systems with a long history of security are available

Lilygo were the ones to make the device the original meshtastic was built on (T-Beam)
