Brusco_RF··on Meta's ships facial recognition on smart glasses
Feel free to solve a problem and release it for free. People do that every day.
Brusco_RF··on Gaussian Point Splatting
I'm working on the vision component of a drone racing stack. Could I use GS to render my living room as a digital playground to train my vision models in?

I know nothing about the technology but the alternative is creating a 3d model of my living room which is also outside my skill-set.

Brusco_RF··on California issues fine over lawyer's ChatGPT fabrications
Jail time? Thats a slap on the wrist. lets summarily execute him and his extended family two generations up and down
Brusco_RF··on The Death of Daydreaming
I wish you didn't just put this information in my brain.
Brusco_RF··on Canada considering charging for road access from USA to Alaska
My only point was that Canada has more to lose than the US if we start taxing journeys through each others countries. A lot of commenters missed that.
Brusco_RF··on Canada considering charging for road access from USA to Alaska
While you make a strong point, I'm not ready to cede it. Canada has winter storms that will close that road, albeit for shorter periods of time than the boulder situation. Being able to re-route through the US is critical during that time.
Brusco_RF··on Canada considering charging for road access from USA to Alaska
>[Canada] may eliminate the US from the world arena

Is this a joke?

Brusco_RF··on Canada considering charging for road access from USA to Alaska
What a lot of commenters cheering this headline might not know is that there is only one single internal road connecting east and west canada which regularly closes. Most commercial routes go through the US. Don't believe me? Route Ottawa to Vancouver in google maps.

This move would amount to throwing rocks from a glass house.

Brusco_RF··on Claude can now search the web
I definitely tried to web search with ChatGPT a few weeks ago and it couldn't. I don't think I'm making this up. Unless I suffered a TBI.
Brusco_RF··on Claude can now search the web
Excited to see how this compares to Perplexity or Gemini. I remember that ChatGPT used to be able to search the web, but last I checked it it couldn't. I wonder why they removed that feature
Brusco_RF··on TabBoo – add random jumpscares to websites you're trying to avoid
A while back I tried to apply this same principle to an iphone case that tazes you at random when you hold it for longer than 5 minutes.

I gave up on the idea for a number of reasons, primarily driving safety

Brusco_RF··on I sent an Ethernet packet
I'll tell you how I learned, I got thrown head-first into a network switch design. I knew almost nothing about networking.

The most useful resource while I was learning was RFC1812 "Requirements for IPv4 Routers" [1]

Its an ancient document written the same year I was born detailing how future routers should be built on this relatively new thing called the internet. The language is highly approachable and detailed, often explaining WHY things are done. It is an awesome read.

To be honest you don't need to finish it. I only read the first few chapters, but I googled EVERYTHING I did not understand. The first few paragraphs took several hours. Talk to LLM's if you need a concept explained. Take notes. In a few days you'll have a very solid grasp.

Brusco_RF··on I sent an Ethernet packet
I think he meant 100MHz. In case he actually meant 100GHz, I would gently remind him that light only travels ~3mm in 10ps

Are you me? This is exactly my job at the moment. Send me an email if you'd like to compare notes
Brusco_RF··on Cooking with black plastic is particularly crucial to avoid
I am old enough to remember when we needed to switch to plastic bags over paper to "save the trees"
Brusco_RF··on In 1870, Lord Rayleigh used oil and water to calculate the size of molecules
My favorite riff on this: at a previous job we worked on a 12GHz SERDES, which meant each inch of the cable had a different data bit on it
Brusco_RF··on Tiny Tapeout VGA Playground
Welcome to Hardware Design! The open-source toolchains come from hell. The closed-source options are supremely expensive and not much better

They don't call it EasyWare

Brusco_RF··on I got almost all of my wishes granted with RP2350
As someone who just picked micro USB over USBC for a development card, there is a significant price and footprint size difference between the two.
Brusco_RF··on I like the RP2040
Thanks for that, looks interesting. One note, their website [1] claims 5uA/MHz, not 1

Brusco_RF··on I like the RP2040
I also happen to be working on an ultra-low power project with an ESP32.

It is hard to beat that 5uA deep-sleep current!

Brusco_RF··on I like the RP2040
No love for NXP in this thread? They make a very similar peripheral called FlexIO [1] on devices like the K32.

>[FlexIO is a] Highly configurable module providing a wide range of functionality including emulation of a variety of communication protocols

It is extremely capable! I have used it to hack together an octo-SPI... which stretches the definition of the S in SPI ;)

Brusco_RF··on Homemade 6 GHz pulse compression radar
One of the main benefits of using an FPGA is that you can compensate for trace length mismatch with timing constraints
Brusco_RF··on Homemade 6 GHz pulse compression radar
That's pretty typical for hardware development. You software people have it too good!
Brusco_RF··on The window for great-grandmothers is closing
And how does their fertility rate compare? Actually I'll tell you, Sweden's is 1.66, the USA is 1.64.

South Sudan, the poorest country in the world, is 4.54

Brusco_RF··on Lifelong Disadvantage: How Socioeconomics Affect Brain Function
I would rather be destitute with my kid than live like a king without her.

>poor people tend to be much better with money than rich people.

This does not pass the sniff test. Lets see your statistics?

Brusco_RF··on New York medical school eliminates tuition after $1B gift
>feel free to have $10 million

Thanks, but you don't get to tell me what I'm allowed to have. This is basic property rights.

>control and impoverish others.

This is quite plainly the fixed pie fallacy[1].

GLP-1 isn't a tangible improvement for a chronic condition for common people?
Brusco_RF··on My experiment in phonelessness was a failure, and it also changed my life
I think an electric shock would go a long way.

Years back I tried to make a phone case that would shock me at random while using it. The idea was to replace the dopamine hit you get from checking your phone with a twinge of anxiety and dread.

I never finished the project. Turns out generating high voltages requires tall inductors, which generally make a phone case unacceptably thick.
