Very cool project! It is fascinating to see that sensor nodes can be time synchronized so well, using standard technology. That is a key precondition here. Localization is still quite tricky over long distances though, especially due to mul

A better development experience would be to use MicroPython. That will require a microcontroller with more RAM and FLASH space, but could equally power efficient. When using the LVGL UI library, and decent drivers for the peripherals on the

Battery size and battery time are the primary constraints for a wrist watch. The power efficiency of a SoC that runs full blown Debian, as well as Debian itself is much worse than the NRF52 used in PineTime. Without doing calculations, I wo

Congratulations to GIMP team! The 3.0 series represents several thousand hours of work over more than one decade. Soon that is over the finish line :)

If you use visible light, then one can use a phone (screen) to blink the pattern to transmit data. An LED can also be used as the sensing element, just need access to both anode and cathode. Charge the LED and measure the discharge time - i

Serialization code should be generic, no boilerplate needed. Object models must reflect the problem domain well, something to think carefully about. Current code assistants is only able to do that automatically for very generic classes.

If they had done performance testing from the start they could have saved a year. A pipeline that has not been performance tested was in no way "finished". Performance is not something that can be tackled on later. In any language

Single process with async if I/O bound. Multiprocessing if CPU bound. Both if the workload is mixed.

If you are I/O bound then asyncio or good old fashioned gevent will do great. If you are CPU bound, then use multiprocessing. If you need to accept "jobs" from elsewhere, use RabbitMQ (with or without Celery). If you have mi

Can you be more specific as to which application areas or tasks you are interested in? Or your goal in learning about this topic? Time series analysis spans about as wide as tabular data analysis...

I recently found the Statistical Rethinking course on YouTube. I found it super refreshing in its very applied focus, direct advice and thorough pedagogy. It assumed that one has a little bit of stats and Bayesian thinking from before, but

I think that price point is fine. Self publishing has a lot of variance of course, but I would not categorically say that 50 dollars is too high. We as potential readers just need to do our due diligence, checking reviews etc. A book not wo

I agree. But it is critical to ensure that what one is improving is something worthwhile. 12% improvement in compute costs for a project with lots of compute spend = massive win. 12% improvement in compute costs for a hobby project running

I am not sure clawing back a significant amount of marketshare can be done with any amount of money. As long as there is no access to a distribution channel that is similar in size and low friction to what the other browsers have, it will a

These things are somewhat ironic, given the focus of the states mission. But is it /really/ a reflection or explanation of any serious problem that the organization has? Is is really an indication that the interim CEO is not capab

Are there other browsers that have successfully built a niche? And how does one use that to bring in enough money to sustain a reasonable sized organization? To me it neither seems easy, nor any guarantee of success.

The realistic timeline to have a business that generates more income for you that than being a decently paid employee is probably around 5-10 years. So one heuristic could be, do you have the opportunity and patience to wait that long for t

Can we please say "written _with_ AI" (or using), instead of "by AI" when describing these things? It is a human in the driver seat, triggering and controlling via prompts. I think the distinction is important because a

I find that Parquet works great for time series data in general. We use it a bunch for datasets of some millions of rows for each of 10-1000 devices, with typically 10 ish columns per device. What I am missing is good support for delta encd

The latest extensions from ARM are codenamed Helium, and they are an extension on the previously mentioned NEON. Both NEON and Helium are quite simple vector extensions, and yes it is also used for classic DSP stuff. I believe Helium also

There are a range of ML acceleration possible on existing chips. The basic 4-wide 8 bit integer SIMD extensions in NEON is available on basically all ARM Cortex M4F chips, which is already available 8+ years. It gives 4-5x speedup for neura

Except the creators are millions of people, and putting many more hours of work in. So their expected return on investment is much much lower.
