If it is as good as the article claims, I would say more like “instantly”. Bringing the resonator on die eliminates the crystal from the BOM, one of the pricier passive components. Also probably two capacitors are now gone, again for xtal c

High desity PCBs are a challenge. Most of the time as hobbyists or for engineering prototyping that density is not necessary. Giving yourself 10% or 15% extra space is hugely beneficial to your sanity. Production boards are a different sto

Actually, of trucks were taxed on a ton/axle basis instead of ton+axle basis, the net road wear would be dramatically reduced. Think 6-axle, tripple-tire trailers.

Only a fraction of military assignments are combat positions. I knew one Viet Nam vet that spent his entire tour in an air conditioned bunker in Saigon hanging tapes on the computer that printed payroll checks. Another, technically in a com

Yes, I did. And I fully expected the schedule to slip. And I fully expect it to slip again. (Hardware is hard, been there, collected the scars.) And I fully expect the software to be glitchy. And I fully expect the user experience to unde

Certainly you have something to say photographically. Keep seeking. Recall that the big names are all remembered for a tiny fraction of their work. Ansel Adams is remembered for approximately 40 photographs, out of a lifetime of art images

Yes, that is kind of non-sensical as written. I'm going to guess that by "antenna" they are thinking of "resonant dipole" and by referring to a trombone, they are saying the grape is more of a resonant cavity. But

Indeed. I have not looked into rocketry for a while, but my recollection is that an active guidance system, active control surfaces, an IMU, all place you squarely under ITAR. Building, much less exporting, without a license is likely a Ba

In DSP when you implement a filter you typically have conflicting requirements. If you have a particular transfer function you wish to approximate, FIR is one choice. It is relatively easy to synthesize, and has linear phase response, and n

The Nevada State Gaming Commission has pretty much solved that. The thing I find ironic -- deploy a voting machine -- Maker: "Oh, no, we can't let you look at our code, it's waaaaay too complicated for you to understand. Tru

Is it a core advantage? Maybe. But smaller code size has beneficial effects on the silicon cost. Choice 1: If you can benchmark the same on important work loads with 10% smaller I-Cache, make the die smaller. Manufacturing costs go down

A time station? Or HCJB in Quito Equador. HCJB used to have a poindinf footprint into North America when I was a kid.

Ha ha! Wonderful. Just by chance, happened to catch it as the top the hour rolled over, so got to hear the full station ID. Great fun. But what do you do about propagation and weather announcements? :) My favorite WWV story: Was helping

Yes, I am pretty sure that is ROS 1. There are a lot of companies using ROS 1, mostly either Kinetic or Melodic. (I am not going to name names.)

I agree. Knocking out a mass a week at least ups your production and keeps your creativity in good form. Another case that I marvel at is Carl Stalling. During the heyday of the Warner cartoon unit he did most of the scores. Yes, yes, no

OK, so I am a ROS fan and have worked on several ROS-based projects both for hobby and for hire. Be aware that ROS has a non-trivial learning curve. I guess I would say that if you are learning robotics, ROS is where you want to end up, b

For me, it was taking time for some self-motivated projects. I am really only happy if I a planning/designing/building something. The way I cure burnout is to stop working on other people's priorities, and take on a challeng

One of the interesting aspects of Hanabi is that there really isn't enough turns to fully hint. So with every hint, you must ask yourself not just "Why is s/he telling me this?", but "Why are they telling me this

I am personally not a fan of details like this creeping into the language spec. CPython is not the only Python. This kind of spec creates unnecessary challenges for Micropython, for example. And of course there is Cython and others. It mak

The distiller I use has carbon filter packs at the output of the distillation chiller (at the top of each carafe where the water enters).

So, you think I should be drinking water pumped out of the ground in Silicon Valley? First of all, the amount of naturally occurring mercury is very high. (The Almaden Quicksilver mine was the largest cinnabar strike west of the Mississip

We bought a counter-top distiller 15+ years ago and are never going back. If fact, I think we have worn out 3 now. Highly recommend.

We were a long-time team. Well calibrated on each other. Fuzzy thinking was called out on a regular basis.

So, do taxis cause a parking problem? No... taxi's are on the roll because if they are parked they do not generate revenue. Every sensible self-driving car company out there is pursuing a ride service model. I don't see people

OK, so I am as much of a hard core Pythonista as you will find. But I don't think it makes any sense to build C projects (or many other languages) with Python instead of makefiles. C programmers know make, the makefile idiom has been
