Digging deep into my memory here, but I always remember that when Zout==Zin that's what you want for maximum power transfer. My guess is that the 1/8 trick is for the typical characteristics of small-speaker headset. Big speakers

I often work with a guy who's a pure computer scientist. He communicates in LaTeX and pseudocode only. I don't think he could find a compiler if he tried. What I've learned to do is keep his notation whenever I implement s

Computational Physics Ph.D. here...I don't know about that. I have written lots of code (not just using off-the-shelf packages) to solve Hamiltonian mechanics and Quantum reactive scattering. OMG, I spent about 30 minutes going throu

I agree with your premise of "don't be distracted" when writing, but for me Word often is the distraction. I use a live-preview markdown editor (e.g., Typora, MarkText) to let me get my thoughts onto paper (screen) with low

Yes. 40 years of debugging with print statement (or MsgBox in MFC during that one Windows project in the 90s...). When I'm mentoring juniors, I always see them stepping through the code with a debugger. They're not really under

I do something similar for my reports. I write most of it in markdown using Typora and then I export the last draft to docx for fine tuning and distribution (the agencies I work with want docx submissions, not pdf, which always bothers me)

Good point. However, the conglomerates just buy ad space on the the powerhouses such as the NYT and they're not as firewalled as you'd hope. The NYT will never allow a negative article go out against someone who has major ad buy

Your first bullet is totally correct, barrier to entry has collapsed and it's easy to do high-quality journalism without the backing of an institution. The people who are good journalists that people want to read have gone to platfor

Seconded. Especially since you're a veteran, look at government (and in particular DoD) contractors. The pace is slower and as an SME you could contribute in many areas.

I did something similar, in fact, the math may be the same thing and just expressed differently. But when I've had to rank non-transitive things, I use Elo ( https://en.wikipedia.org/wiki/Elo_rating_system ) Many y

Yes. My company bills me out at roughly 3x what I see. And when I do a side project for someone, I bill the same 3x rate - and even though it's more money in my pocket than my day job, it's more hassle and not clearly a better a

I love this! I typically use a separate text editor for things like this, but the block idea is great and works with how my brain likes to group things. I know this is expanding the scope and complexity and probably opposite to what you&#x

Yeah, this is how I read TAOCP. I was a grad student working on computational chemistry, so I had lots of downtime waiting for code to compile or long calculations to run (and I didn't have the fancy cloud to run tons of stuff in para

I had forgotten about modem compression. Back in the BBS days when you had to upload files to get new files, you usually had a ratio (20 bytes download for every byte you uploaded). I would always use the PKZIP no compression option for t

But it's even worse than that. Since universities are funded by the grant overhead (30-40% of the grant goes directly to the university, sometimes higher), there's an incentive for "expensive" research. Why fund a theo

Actually, all cause is the right metric. Let's say the vaccine stops 100% of malaria but causes severe heart attacks. You'd probably want to know that. I didn't review _this_ study, so I won't comment on the quality o

Yes, good find. One description that always resonated with me is the tradeoff between capacity for repair and uncontrolled repair or cancer. Think of two extremes: 1) no capacity for repair: once something is damaged, the cells don't d

Yes, the heart really has no capacity for repair. It just simply scars over. That's why things like "transient myocarditis" are scary. The inflammation may be transient, but the damage is long lasting.

I'm a principal so I rarely write code now. I probably do 6 PRs a year, basically when its directly related to my expertise and it makes more sense for me to do it. But when I do, I really try to guide the reviewer into my thought pr

I always use p for pointers, but not p_. Mainly it's because of aesthetics when scanning code. The -> operator and the _ always break things up too much for my brain. If I'm in a well protected piece of code where I know I d

Yes, this is a hard calculation to make. A couple of years ago I would also have said that a PhD is not worth the opportunity cost. I look back to the the time when my wife and I were both fresh out of college and in our PhD programs. We

The "setup this benchmark" happens in medicine all of the time, and it's super insidious and no one sees it. It's hard to tease out. For example, say you have a new (patentable) drug that you're trying to get appro
