The tangible hardware difference is the MMU. S3 didn't have a proper one. This new chip does. But the biggest difference is the intent. Microcontrollers focus on peripherals and are used for interfacing, data conversion and signal processing. They're meant to run either bare metal firmware or small RTOS. OTOH microprocessors have in addition to an MMU big caches, high IPC numbers, wide bus lanes, everything you need to run different workloads as fast as possible.

Technically a chip can excel at both.

They're not single board computers. They're microcontrollers. Or rather they were until this new chip was introduced.

Originally it was the more capable successor to ESP8266, the super cheap chip containing a high speed core with wifi and an IP stack. At one point it powered a huge chunk of all smart devices on the market. Then the original ESP32 was introduced as the successor, with BLE and two cores which were even faster. That made it a very capable chip for tasks demanding compute. After the original ESP32 they decided to add variety and make a whole "ESP32 family" and yes there's quite a lot of variety these days. Even the ISA and cores changed.

Isn't that the point? The camera glasses add a 10x harassment factor.

I'd rather go the other way and entirely decouple my online identity from Google (or Apple/Meta/Microsoft). Much better than constantly worrying about some crappy AI deciding to ruin your life with no recourse.

Isn't Q8 way overkill these days? I see many graphs showing Q4 or Q5 having less than %1 deviation. Nvidia's NVFP4 Qwen quantization should be even better due to its better training methods.

aka a stroboscopic measurement,

but I don't think it will work well for this case.

Late by a decade or more (JSR310 was released in 2014), but still a good development. I've tried convincing colleagues to use js-joda in the past but they thought they were keeping it simple by sticking to moment.js. They weren't.

Isn't the US stock market betting on AGI and superintelligence in the next decade? Maybe a lower population won't be as big of an issue, or even an advantage.

That's a neat software solution. My first inclination would be to grab a soldering iron and replace the crystal with either a TCXO or a socket to provide an external clock disciplined to the 1PPS.

That's also the most tiresome part of driving and has the least risk due to low speeds. Easy win for FSD. But for all other cases it becomes a complicated ethical question.

Finally there's a new stepping (i.e revision) for the RP2350 die that fixes the E9 bug that has plagued the chip so far, causing excessive input currents on GPIO pins which made internal pull-up resistors useless and made high impedance inputs impossible.

GPIO pins are now all 5V tolerant too!

Instead of a moonshot micro kernel, why didn't Google just build and maintain a new Linux driver API/ABI layer with backwards compatibility and security? Not an easy endeavor, but is it harder than Fuchsia?

I made my DEs somewhat pretty but never got too deep into ricing. Then I switched to i3-gaps. But I still spent a lot of time configuring and comparing terminal emulators, shell prompts, completion, vim plugins, iommu/vfio...

At one point I got sick of it all and decided to switch back to Windows/MacOS, not configure anything too heavily, install tools when I need them, and use all tools as vanilla as possible. Besides not having to maintain all this stuff I also realized I could then ssh into any machine and not miss my customized tools.

New comment by ckocagil in "Gumroad CEO is no longer hiring junior/mid-level software engineers due to AI"

ckocagil — Thu, 06 Feb 2025 15:36:39 +0000

All the "AI software engineer" hype is about one thing: suppressing developer wages. Steve Jobs used to do this covertly, to some extent, with his "no cold call" anti-poaching agreements.

It's a multi-prong attack. One angle is the interest rates and mass layoffs. Another angle is AI. There are more ridiculous ones, such as this "study" that claims 10% of devs do literally no work: https://x.com/yegordb/status/1859290734257635439 - I expect many such studies to be conducted and generously funded by the industry in the coming years.

The big irony is how all this talk will lead to a decrease in the software engineer supply. Why would anyone choose a career that's about to die?

I picked those particular chips is due to their extremely good performance at a reasonable cost. Check their THD against AD797 and LT1115! :)

For any consumer use to play back audio I can't image a scenario where TL071 wouldn't be enough. And you'd rarely even need an op-amp when integrated solutions are available.
