Just nope out of the whiteboard interviews. There are lots of places that need you that don't do them.

"The fundamentals" can cover an immense amount of ground, especially if you're old enough to have worked in a lot of different sub-fields.

Linear time suffix tree construction. You have 90 seconds. Go!

Re:New features you can't use unless you are in Python 3 on Wednesday June 14, 2017 @02:51PM (#14555031)
Of those, only the async I/O stuff seems compelling. But compelling it is, at least as used in Curio. It feels like this is still shaking out, with the standard library and Trio (?) alternatives, but it looks really cool.
Re:Is the keyboard faster than the mouse? on Tuesday June 13, 2017 @12:42PM (#14546147)
Spent some time on this a while back, and even wrote a driver that let me use a game controller as a complete replacement for my keyboard and mouse. Interesting but not really successful.

One key takeaway: The input bitrate that a competent typist can get from a keyboard is quite high. As a guess, it might be 8x higher than with a gamepad or mouse.

And as an additional detail, I've had more RSI issues with mice than keyboards over the years, even though I use emacs.

Rationale for "make install" rediscovered. Film at 11... :-)
It could well turn out that the common factor here is not consuming a lot of highly refined carbohydrates (sugar, flour, etc.).

More importantly, metabolism is just incredibly complicated, with many complex relationships and effects. On top of that, there is significant genetic variation, so these will differ across individuals. For now, we pretty much have to experiment on ourselves and observe what works.

Re:Prozac Nation Is Now the United States of Xanax on Monday June 12, 2017 @02:53PM (#14539925)
Breitbart and The Nation both have a rather dramatic skew. But, since it's obvious and generally consistent, it's relatively easy to "null out". This leaves you with additional signals that are still relatively uncorrelated with (say) the NYT signal. This can provide additional information, and sometimes it leads by several days or even weeks, which is interesting.

(If I had a source of future stock price deltas that was almost always "wrong", I could be a very rich man.)

That said, I've personally come to the realization that my marginal hour spent reading daily news is generally better spent reading ancient philosophy. News is certainly addictive, but I'd be hard pressed to come up with examples where it's improved my life.

Overt opinion is pretty easy to spot. Subtle "editorials" in the form of omissions, slanted word choice, etc., are harder, esp until you start looking carefully for them.
Re:Prozac Nation Is Now the United States of Xanax on Monday June 12, 2017 @01:26AM (#14535336)
Try breitbart and thenation as alternatives, for example. Sure, some of it's drivel, but after a while you'll realize that some of the NYT is drivel as well.

And actually, if you just carefully compare NYT _headlines_ to their corresponding _articles_, you'll realize that the headlines really are pretty crappy. Certainly nowhere near the standards for headline writing we used to have in ninth grade journalism class.

I really hope to see a resurgence of classical quality journalism. But I'm not optimistic.

Re:Prozac Nation Is Now the United States of Xanax on Sunday June 11, 2017 @03:29PM (#14533364)
If you think the NYT is unbiased, you might do well to read a few alternative sources for a while to compare and contrast. Once you've been to other lands, it's easier to spot the oddities of one's usual locale.

But more importantly, even if the NYT were entirely unbiased, that does not mean that it's good for your mental state to be reading it. Being exposed to a lot of problems that you cannot do anything about might not be a good thing.

Re:Whiteboard Interviews Suck, Get Good at Them Anyway on Thursday June 08, 2017 @03:50PM (#14516689)
If you select stringently for WBI ability, you'll get strong WBIers. However, you're also paying the opportunity cost of not selecting for other traits and skills that might matter a lot more.

+1 though for "Senior Whiteboard Engineer"--that term is genius!

Re:“Let her speak please” on Wednesday June 07, 2017 @01:38PM (#14508293)
"Informal study"? Isn't that an oxymoron?
Re:Whiteboard Interviews Suck, Get Good at Them Anyway on Tuesday June 06, 2017 @06:58PM (#14502213)
Conversation, half technical and half to figure out what the person would be like to work with. For example, tell me about the most interesting/difficult/satisfying problem was that you've worked on. Or, tell me what happens when you point your browser at a web site, in as much detail as you can muster. What are your go-to tools to solve problems
Re:Whiteboard Interviews Suck, Get Good at Them Anyway on Tuesday June 06, 2017 @03:38PM (#14500502)
There is kind of a symmetry to it. Get a question that the asker has studied and watch the answerer squirm. Seems like it'd be more fun, and probably more insightful, to take turns... :-)
Possibly true, but I cannot think of a worse occupation to get into right now, with self-driving trucks on the horizon.

(Also, I have a trucker in the family, and the financials are harder than they look.)

Re:Ask HN: Books you wish you had read earlier? on Sunday June 04, 2017 @07:51PM (#14484383)
Haven't read this specifically, but agree with the concept. Also recommend The Psychopath Code by Pieter Hintjens (the ZMQ guy). Most books are ultimately quite abstract. A few are useful when the shit really hits the fan.
Re:The Pleasures of Pessimism on Wednesday May 31, 2017 @02:48PM (#14454933)
I ran across this "book" recently as was impressed by how deep it was, compared to the vision presented in Sunday School (and a certain 60s pop song).

It's a bit hard to read. Start here: https://www.cliffsnotes.com/literature/o/old-testament-of-th...

At a societal level, I'd prefer that companies didn't act irrationally. (I don't believe in justice per se.)

But at an individual level, you have to play the cards you are dealt. There is a huge amount of noise in the system, but play them as well as you can.

At 53, it hasn't had much effect on me as far as I can tell. The first time I noticed was at about 45, where a SV startup that seemed extremely enthusiastic nope'd after seeing me on Skype.

IMO, there's just not much to be done about it. My skills are about as good as they ever were, and my long experience can be extremely useful. Some employers will hire that and some won't.

Can you just keep your devices stateless? This works for me.

Maybe, but I suspect the effects of stupidity would be so strong that you'd never be able to detect the effects of a hostile nation.
Re:Do We Overvalue Bike Lanes? on Friday May 26, 2017 @08:47PM (#14428290)
Funny, as a pedestrian, I daily observe that any sidewalk a bicyclist is capable of riding on will be entered by a bike, with resulting risk of injury or death to pedestrians. I have indeed daydreamed about ways to introduce barriers to prevent bicyclists from riding on sidewalks, but without success. Any ideas?

What downsides do you have in mind?
Re:Rich Retirees Are Hoarding Cash Out of Fear on Friday May 26, 2017 @09:28AM (#14423837)
You might rather enjoy it though.
I'm terrible at talking, and certainly at bullshitting. It happened that I was an excellent candidate for the role, but perhaps they might have hired a bullshit artist instead.

But I don't think so. I think I can often smell bullshit just by its sound, and I think a good manager could do even better.

Beyond that, you can be great at the whiteboard and still full of shit.

Re:Why I Quit Being So Accommodating (1922) on Thursday May 25, 2017 @05:16PM (#14420201)
It's like the good side of Zeno's Paradox. If you're alive at age X, your expected number of days to live is still significant. For US males, your life expectancy doesn't fall below one year until you're 113.
Apparently humor is dead.
