I work in semiconductor manufacturing, it's a very common model. I have been in about eight fabs around the world that use it quite successfully.


I think about this all the time:

Would it be possible to change the anti-trust laws so that companies can not merge or be acquired if the sum of their assets and revenue exceeds a set dollar figure adjusted for inflation?

If A(assets + revenue) + B(assets + revenue) >= $, then not allowed to merge.

This will promote competition from upstarts and increase the efficiency of these companies by preventing them from gobbling up every new market.


To my surprise there is a museum right down the street from my house (Beaverton/Portland, OR USA). That I must have just been missing. Thanks for posting!


Glad to see my post brings a nice trip to you.

From the comment sections, it appears to me that Hacker News has no shortage of hobbyists and professional electronics engineers, but when I search relevant terms like "Tektronix", "oscilloscope", "spectrum analyzer", or "SPICE", there's no much information here, only two or three top articles. I guess it's unfamiliar to the Silicon Valley CS majority who doesn't have enough appreciate of hardware engineering. I'll try to post more of them in the future.


Absolutely go. I repair these scopes as a hobby and the people at the tek museum have been endlessly helpful. Repairing old tek designs and reading the schematics has made me a much better analog engineer.


Hey I'm in Cedar Mill and used to live practically across the street from Tektronix. My email is in my profile if you want to get coffee or check out the museum together. :-)


Wow. Great community here on HN. Kudos to you.


One thing I never understood was why server1.mycompany.com (origin) cannot make a GET request to server2.mycompany.com?


For cases where shared hosting issues subdomains for users I reckon.


My former employer threatened me in Oregon (started as an intern, software engineer). I had to pay a lawyer $4000 to help avoid going to court. Basically they were trying to scare other employees from leaving.


So you’re both of some money, but in the end, nothing was actually enforced, and their reputation is trashed? This is exactly what I thought would happen at worse.

Meh. Next time, have the new employer cover the legal costs. 5k is not much to spend when onboarding a new employee. That’s basically IT costs.


Any Friends of DeSoto here?


My wife's experience:

PI: "You put your kid in front of the TV for 2 hours a day to get stuff done? That's terrible parenting."

PI: "You will be late 1 day for a meaningless group presentation to your own lab, because your child is sick and can't go to daycare? Get your priorities straight."


Why was it your wife’s problem when the child was sick and not yours?

EDIT: Sorry, I just assumed that you didn’t equally stay at home when the kid was sick. How did your boss react when you didn’t show up?


Note that it wasn’t him criticizing her - it was her boss, at least assuming PI means principal investigator.


Raising children is a full time job. The broader problem is that the discipline is not at all treated as a profession. Instructors for those children are recognized professionals, but the guardians are not.

If you want to be good parents though, it is your imperative to put your kids above all else, which will naturally dissatisfy any members of the "all else" who don't have your well being and success as their priority.


This is what husbands are for.


Can not recommend the book enough. I read the entire book in PDF format first. Then went out and bought a hard copy.

I work at ADI now, which is kind of weird to see the OP's link.


Ex-ADIer here, we had a couple of copies kicking around in our office. Shortly after I joined I asked my team lead what an FFT is, he explained "it's a way to transform a signal from the time domain to the frequency domain..." and when he saw that my eyes had glazed over he pointed to this book and said "read that". It's really readable and an excellent intro to DSP


From the blog quoted above: "Advanced DSP can certainly get complicated with quadrature processing, Hilbert transforms, and cascaded infinite impulse response filters, but this series on DSP isn't going to get that complicated."

Gulp. I'm new to DSP, so I'm obviously not going to jump into "quadrature processing," but what would you say are the basic mathematical prerequisites for getting into this kind of thing? What sort of math should you know before you even start?


I'm afraid I don't know that info - I worked with the compiler toolchain and associated libraries so strictly speaking it probably wasn't even necessary to know the basics of signal processing. However it gets -complicated- interesting enough to be challenging, and whatever the next steps are this will at least put the necessary groundwork in place :-)


To get started all you really need is trig. As you progress you'll need more advanced math.


Yes, Oregon's wage limit (4 person family) and 18 time limit help...

This coming from someone who's former employer tried to enforce a NDA on me.
