One of my gripes with web development is that it looks like its primary driven by fads. A LOT of companies change the whole stack just to copy the latest gimmick they’ve seen somewhere else. Devs need to be constantly relearning how to do b

One of my physics professors used to make a joke every year about how we could read every athletics book written, but we would not start to win races until we hit the track (at some point he made a fun video of him studying “how to run” to

I’m also willing to bet you live way up the stack. Try debugging something in the embedded world, and you’ll see why a lot of bare metal programmers use printfs. Turns out timing is critical most of the time, so using a debugger hides a LOT

1. Except now you need a new PCB, a new subassembly, new procedures... 2. You need a lot of fancy things, just not cell balancing. That “battery health indicator” all iphones have, guess where that’s from. You can take it from someone who h

My take from experience and from what I've seen with friends: - Consulting is great for people with good people skills, but it can turn into hell if you haven't them. - It's very easy for experienced workers in some shops to

I'm not talking about NRE costs, I'm talking about very real manufacturing costs that you are ignoring. Modern battery packs are one of these things that if you haven't designed one you tend to think they're simple, but

Would you want it enough to pay 20% to 30% more and have the phone be ~5mm thicker? Because the obvious issue is that most people won’t.

Except it isn’t, not with modern lithium based batteries. Now most devices use direct voltage, coloumb counting and battery impedance to keep track, and that’s with known batteries.

That’s how bubbles work. IMHO, the best case scenario for crypto is that they are the web companies of the 2000s, so there’s a chance some of them will become an amazingly profitable investment, while most will go the way of pets.com. And t

However flawed our current measurement systems of IQ are, IQ is a monotonic predictor (i.e. its correlation with several measures of success is strongest with lineal functions that with functions with local minima). That is to say, better

The problem is that forwards takes a lot of time (which is bad if you intend to make your career on it) and backwards suffers from survivor bias.

To me the most non-sensical part in this kind of arguments is that most of the people identifying themselves as “Latino” are people from the US. Most people actually born in latin america will self-identify with their country of origin (Arg

I know, but clock rate tends to be a good proxy, especially im cases like this. For a bus like I2C there’s basically two possibilities: 1. You are using a part with a clock rate that extends clock rate over the standard, which means you ha

If you are getting reflections at 400Kbps, you either have another problem or are way out of the standard. There’s a reason for things like RS422/485. The hardest bug I’ve seen on an I2C bus was an implementation that every now and t

For I2C addresses are hardcoded, with some chips leaving some bits to be set by hardware configuration. Far more interesting in that regard is the SMBus, that is compatible in most cases with I2C but can handle things like address resolutio
