Well, you do get vacuum tubes that operate up to a terahertz - they don't count as solid-state devices, though.

Well, it does go on to say:

> This observation, which has a significance of 5.9 standard deviations, corresponding to a background fluctuation probability of 1.7x10^-9, is compatible with the production and decay of the Standard Model Higgs boson.

Technically it could be another particle with a 126GeV mass, though that's hopefully something more experiments will show one way or the other.

sigh, tell me about it. Writing to info@yc doesn't seem to help either.

I think Fravia+ would have actually liked what you have here - its a really nice search engine.

Late reply, sorry. I never even knew they had the option of an XMPP server. For what it's worth, I find the mail experience to be both reasonable, and pretty much fat-free, which I guess is all I really need.

fastmail's non-free service, maybe? I got it a very long time ago, mainly for the .in email address. It's been no-frills, fast, and (mostly) reliable. I'm still not sure I'd recommend it to a gmail user, but its been a good email account to have.

For what it's worth - and not to distract from your real point - Exponential (or the more general Lyapunov) stability are a better explanation of instability. Stiffness is more a property of the method used to solve the ODE, rather than of the ODE itself.

Email threading has worked for longer than I care to remember in mutt, for whatever it's worth :)

Bridge might qualify, depending on how you play it, but otherwise you're right.

If I remember correctly, I (reluctantly) had to switch to t-bird back in the day because it didn't do STARTTLS+IMAP. It was perfect, otherwise. I'm yet to see a faster way to search through mail.

Wow, there are a lot more EDA programmers on HN than I'd expected, some of whom I even recognise by name.

On topic, it's probably easier to embed Lua than Tcl, though you may miss some of the libraries. The language is cleaner (in some sense). For an EDA application, the only real problem is what your customer is supposed to do with 20+ years of scripts that they've written that are specific to their flow :)
