Modelling has come a long way in the past decade, probably to the 'close enough' level for just about anybody. Still doesn't quite have the sound or feel of the real thing though.

Very few classic tube guitar amplifiers were Class A, the vast majority being AB. Really the only ones that were class A are single tube amplifiers like the Fender Champ. The Vox AC/30 that everyone thinks is class A is just cathode-biased class AB. The Marshalls that Hendrix played through, the Fenders that Steve Ray Vaughn used, and the Boogies that Santana is known for, all class AB.

Sure, class A does tend to have more even-order harmonics, compared to AB, but even class AB tube amplifiers have more than any solid state one.

So... did these tube AB designs have particularly asymmetrical lobes to their gain curves? Otherwise I don't see where these even order harmonics are getting introduced.

Yes a bit due to asymmetry in the phase inverter circuit driving TD push-pull, but mostly because the odd harmonics are naturally cancelled out in the output transformer.

I've been thinking about getting into react native lately, and I needed something like this.

Thank you!

I've been using Bash for Windows at work for a couple of months, and it's mostly been good enough that I don't need to fire up my ubuntu vm anymore.

The biggest problem I've run into lately is that I really want to be able to run GUI-based programs, and even though that does worth with VcXWin, it's kind of crappy, especially for font rendering.

Anyone know of a free (or cheap) x window server for windows that does anti-aliasing?

I wonder if MS finds a way to port open source Linux apps in Windows 10.

Isn't WSL the shotgun approach to answer your question? There's no need to port thousands of useful tools; create the WSL and poof! most of it runs out of the box, natively, in Windows.

He really understood his role well. Unfortunately, this is pretty rare now.

I think people who are picking up on the 10x assets thing are missing the point... Money can help you feel better about things when things in general aren't going well.

What he says about missed opportunities, and working for idiotic management, that's the big thing here. You work your ass off, the management does dumb things, so the thing you're working on never really pays off, in money or fun.

The fact that his sister has 10x the assets is kind of an insult after injury kind of thing.

I think the disconnect between management and the developers is worth discussing.

Its important for management to understand the difficulties and decisions made by a development team to properly create a roadmap for the business. I think the author is expressing that the lack of respect for the programmers opinions can be detrimental.

It's more that in a business (which is a power structure optimized for efficiency - meaning hierarchical power structure) the programmers are at the bottom of the pyramid. Involving their input would take far too many layers of overhead; so the decisions get made further up where there are fewer people to consult (and hence more efficient).

IMO it is essential in today's world to have competent engineering management in the room whenever any major product decisions are made.

This is probably why there is so much poor software about.

That sounds like the underlying problem at heart and is why I started down the path of being more customer facing (combined with getting quickly tired of all the nerd stereotype personalities as my immediate coworkers). The reward for incompetence and the perception-driven careers that is so common with professional managers is a slap in the face to everyone that not only are under them but to those that have to live with the consequences of their negligence. There are some that get kicked down, but typically they'll just find another sucker and continue on and on with self delusion that they've actually brought any value besides some vague association with some rich people to the company.

The problem that really bugs me as well as a lot of others is perhaps more deep-seated - that the popular kids from high school really do win anyway and become your bosses, and stories like Steve Wozniak or Bill Gates where smart, technical people can get ahead of the incompetent but very personable charlatans are becoming less and less common. That confidence / arrogance really are enough to succeed (many do work hard but so do the majority of technical workers too with almost none of the rewards) in the eyes of US society is a lingering thought.

The work itself has to be worth it, or it's not worth it. External motivation has a low multiplier.

It is so oddly ironic for the idea of wanting assets and property to be so anathema on HN.

This is really cool.

My wife died of a tonic-colonic seizure 11 years ago. Something like this might have saved her.

Any chance that you've put the code out there somewhere? I'd love to see it.

I'd love to see Contiki run on something like the beagle bone black.

Why? Linux covers that kind of hardware so much better already.

Agreed. I ended up settling on RTEMS, which isn't an RTOS, exactly, but it might as well be.

RTEMS certainly is a real time operating system. It was initially used in missiles and the original meaning is Real Time Executive for Missile Systems. Later adopted for generic military, scientific and space use.

I think it is a great open source RTOS. FreeRTOS and Contiki are good but not really comparable. Their focus is on smaller more memory constrained systems.

Thanks Everybody for the suggestions
