Nice to see a clear example of doing this entirely locally on a MBP. It ran >2x faster on my M2 MBP compared to the numbers they showed for an M1. Only 23/25 of the test cases passed for me on the fine-tuned model following the READ

Thanks for posting. I've always had an appreciation for language, particularly concise, poignant, highly-visual word images that seem to snap you out of your mental lull in a handful of syllables. For the most part poetry, however, was

As someone with dual citizenship through marriage, and having lived 15 years in France (and speaking French at home despite English being my mother tongue), I'm amused and dismayed to discover than I'm the proverbial Karen of my a

I can empathize with the gut reaction, and the title is clickbait-y, but the article does elaborate that it's not the same tired trope of privileged kid drops out of Stanford/MIT/Harvard to become startup billionaire: > he

Indeed, I'd hate to be the recruiter for that. I can't imagine the kind of psychological profile you'd need for something like that. The end of the article describes the psychological cost the investigation had on the investi

Thanks for taking the time to post this, and I'm sorry you had such a sh*tty start to life. I think it's important to repeat this over and over that the lines are so blurry with content online, and it's not really getting bet

Sorry if this is too long form for HN, but if you read the article you clearly have some patience as well. I'm surprised all the comments here seem to be solely around the technical details with blockchain and crypto. It's HN, I g

For the past two years, I've been working on and off on a basic, open source scientific computing library in C (basic linear algebra on embedded devices, etc.), and hired a student this summer to work on adding some orientation algorit

The same concept is also used in smaller embedded systems, like Zephyr RTOS: https://docs.zephyrproject.org/latest/guides/dts/index.html Useful video if you're interested in how DT applies to Zephyr, suc

There clearly aren't a lot of good bedfellows to be had in the region. US engagement in ME politics is rife with contradictions and blind self-interest, as are political calculations in the EU, China, or anywhere else with enough reach

Historically, this hasn't always been the case, and the US were actively opposed to Israel's covert Nuclear program, for example, which was built with French support against the wishes of the US government at the time. The world h

It tends to be a very small world where you get to know everyone after a certain point, or you know someone who knows someone, and jobs tend to be had by word of mouth. If you have a good reputation (which can be gained working on problems

The number of PRs and committers is what boggles my mind ... it's an endless stream, which is highly unusual for an embedded project. This is where the momentum and technical investment is happening today for open source embedded, IMHO

I guess it depends on the problem you are debugging. I rarely fire up my oscilliscope anymore (maybe once or twice the past year), but it's hard to replace a cheap logic analyzer when writing drivers for new sensors. You really want to

I certainly don't disagree, and wrote many an Arduino library and drivers and tutorials myself. As long as you eventually take the training wheels off, and know that Arduino isn't a path that leads to being able to create financia

Update since I should have mentionned HW as well. If you're looking for something to play with at the HW level, it can be overwhelming to know what to start with. Stick to Arm Cortex-M. That will get you the furthest the fastest IMHO.

by ktownsend 5y ago
Like any niche, it's hard to know where to start and it also depends if you are more interested in HW design, or the firmware side of things. You need some knowledge of both since they overlap in many areas in embedded, but they are di

Exactly. Measuring things at 10-200 MHz is easy and relatively accessible, and there are only so many things that can go wrong. Dealing with anything in the GHz range is not only extremely expensive (order or magnitude more), but you also s

If you want to improve, look at an open source project with a lot of momentum, and learn from what people are doing there. I'm actively involved with Zephyr RTOS, for example, which is backed by the Linux Foundation and has people work

A logic analyser (Saleae Logic, etc.), a HW debugger (J-Link for Arm/RISC-V), a good quality multimeter (spend the extra money here, don't get the $10-20 crap DMM off Amazon), and an entry level 200 MHz oscilloscope (Rigol, etc.)

Similar route myself, though I've been in embedded longer. I do appreciate the relative stability of embedded, where in many ways I feel like we're still living in the 90s when you could realistically master the whole chain of too

This looks like it has a few additional post-processing steps, although those aren't complicated to do yourself either.

I've had to do this semi-manually several times based on plots in sensor datasheets, and this would have saved me some effort. I've previously used: https://automeris.io/WebPlotDigitizer/

The string is a BASE45-encoded payload that has already been signed before encoding as a QR-friendly string. The BASE45 is because QR codes only support 45 characters (versus more common BASE64). But by the time the string -> QR happens,
