I've actually done the opposite in a way - trying to ween myself from most social media in favor of more relaxing forms of entertainment. More in the direction of video games or YouTube science/engineering videos than traditional TV, but I still feel it's a better use of time and helps me to relax better for the next day at work than say, getting in a big argument or reading some extremist political thread on reddit or twitter does. That stuff was eating my time in ways that just left me angrier and deriving less enjoyment out of my life, firing up Red Dead or watching Technology Connections or Tom Scott - decent improvements in my book, if still a "waste" of time.

Buy This Homemade Nuclear Reactor for Only $3,000 in New Zealand
I keep Cable TV for the WWE shows. The DVR records them so I don't miss them. WWE has a ton of lawyers looking for people who pirate their shows, much more than Disney or others. So it would have to be streaming services like WWE Network to watch them if Cable TV is gone for me. I got Amazon Prime Video, Disney Plus, Hulu, etc.
This cult-like attitude about geometric algebra is something I have never seen in any other (legitimate) field of math. Not sure what to attribute it to, maybe Hestenes being a bit of a crackpot?
> Just like Alex Trebek is probably a big part of the reason for Jeopardy's longevity, I think Scott was a big part of the reason for HQ Trivia's popularity.

Scott was a great host, but Matt and Anna are both great hosts as well. I don’t think anything will happen to Jeopardy, since it’s not a host-centered game in the first place. There are examples of shows pulling off a host switch successfully: new hosts of The Great British Bake-off aka The Great British Baking Show are actually quite better than the original team.

If the car avoids 99% of crashes, but crashes happen 1% of the time, and it causes crashes 1% of the time, then it's making you less safe.

Those are just arbitrary numbers and a simplistic framework, but the point is, you can have a huge increase in safety by the numbers, and a very small increase in problems due to the safety system that cancel it out, because the prior underlying rate of crashes was pretty small.

I think this is an abstract pattern that comes up in other contexts and it doesn't seem to be intuitive.

You do sometimes get weird effects from top heavy structures like that though. The classic example is Google hiring “super good people” for them to end up doing pretty low level (but important!) ops work

To take Amazon as an example, you can hire a bunch of high performing engineers but you still need people actually putting stuff into boxes so they get shipped (robots nonwithstanding)

Note that the a Secret Service, ATF and ICE are all sub-departments within DHS, although there was talk as recently as this month to move Secret Service back to Treasury Dept. It does seem clear that some of these departments have lesser tarnished reputations than, say, CBP (which generally struggles to recruit anyone literate, let alone the standards of the FBI or Secret Service).

Built-in 2018 and forged from the depths of physics. A mighty machine arose from a seemingly normal garage in suburban Blenheim. After a year of working two part-time jobs, researching, and building, the science fair project was complete! In its current state, a beautiful plasma generator stands. However, by adding the second isotope of hydrogen into the plasma void. A tasty nuclear reaction will ensue!

Refer to comment surrounding Ministry of Health

Selling to afford university!

Note: All the electrical work has been completed by a qualified electrical engineer. The transformer should not be left on at max for longer than 20 minutes.

Below is a list of parts:

- 10mA, 2kV - 15kV, High Voltage Power Supply (with spare electrical components).
- A-i220, 7.5 microns, 2 Stage Vacuum Pump
- 0-260VAC Variable Laboratory Autotransformer (Variac) - 500VA.
- Extra 2.4m of High Voltage Silicone Rubber 40kv Wiring.
- Lead shielding cover - 4ish mm thick
- 20 grams of liquid Deuterium.
- Body constructed with stainless steel 1.5inch Tri-Clamp flange fittings, including, T sections, sight glass, end caps, ball valve, and rubber seals.
- Custom nickel electrical feedthrough rated to 20kV 15A. Originally mounted to a QF16 flange but now welded onto a 1.5inch Tri-Clamp blank.
- The frame can be added for free! (It's a bit gash)
- Hose clips are not in the photo but do come with the purchase along with a few spare SS fittings.
- Grounding alligator clip and wire.

Disclaimer

This device currently stands as a working plasma generator (effectively a display piece).The next step is for a very brave person to start a nuclear reaction with the deuterium and some silver. 15KV is at the low end to initiate neutron production but I have talked to a few people that have achieved it with similar conditions. The purpose of the reactor currently is just to make nice purple light, the potential for the reactor is to produce neutrons for other projects.
The article shows us transistor level logic circuits to
study, but I think the quick answer is as the architect Seymour Cray gets the credit.
It depends on your definition of vehicle.

I bet we see a few Level 5 flying cars before we see Level 5 ground vehicles. Roads are more complicated than the airspace.

Flying cars are unlikely to be as mainstream as cars due to energy requirements though.
Jeapardy has always done shows like that over its many decades on the air.
Based simply on the current “dig up everything we can while it’s still worth something” push from the industry, it’s clear they’re dead in the water with a lot of soon to be stranded assets.

Much like the tobacco industry, they have sway.. right up until they don’t.
There's something about many non-TV watchers that compels them to announce that they don't watch TV, with a crazed look in their eyes and desperation in their voice, pleading with the world to validate their religious beliefs. I picture them occasionally cracking, hunched over in the closet with a blanket over their head, watching Adam Sandler movies and crying in shame.
I’ve done some cloze deletions for math and related things, but I generally feel like having almost the whole proof in the prompt gives me too many cues. It often leaves me thinking that I indeed wouldn’t be able to come with the answer with fewer hints.

What I’ve tried the last couple of attempts is to “chunk” the proof (also terminology touched on in Barbara Oakley’s course) so that I end up with a question that’s something like “what’s the high-level idea / approach in the proof for X?”. That card would likely require an understanding of some underlying concepts or “chunks”, so I add questions for these too until I get to something that’s less abstract and easier to rederive.

I’m still not 100% confident if this will work well when these particular cards get into the 6-month range or so, and they start showing up at completely unrelated times. My main concern is that if I’ve forgotten some idea from “the middle”, it would be hard to reason about cards that build up on top of that.
The secret is to skip FAANG and alikes. You will be surprised how many highly paid and quite interesting jobs outside of that overhyped circle.

It's incredibly hard, and would take years for anyone to come up with any algorithm from first principle. Which means that any test of algorithm is a test of knowledge, rather than "how you think" or "being able to reason about subtle behavior in system" etc. You looks good if you already have the knowledge, and you will look like a clown otherwise. That is okay if you also realize that the breadth of CS fundamentals are incredibly broad and everyone only knows a subset of it (ask as many simple things as you can).

My deadlines are measured in months, weeks and in the minimum, days. There is practically no cases where it is in hours, and absolutely no case where it would be 30 minutes. I (We?) have trained myself to work and deal with deadlines/pressures of those standard time frame, which means that if I have only a day to deadline left, my technical mind shut down and it is now thinking about the business to see what should be best done next.

I believe people would feel more pressure at the risk of failing an interview than the risk of their company's product having a downtime

I meant to ask about the transaction period of the first row (my bad, "superseded" is ambiguous), but I think I get that one now: the transaction period is still open because we still believe (and probably will forever) that that's the correct validity period for that address. Is that right? And the validity period for the middle one never closes because there's never a time in that row's transaction period where we know the end of the validity period.

The intuition I'm building is that the validity period is metadata and the transaction period is metametadata. I think the similarity between them is a little deceptive, since the validity period is in some sense just another piece of data sort of controlled by (or interpreted in light of) the transaction period, which is itself a way to simulate versioning the whole database; I think of it like the internal representation for a database wrapper that lets you time travel in a database with a history-oblivious schema. In that vision, validity periods are actually part of the history-oblivious schema. You could totally have "transaction periods" for stuff with no concept of validity period, e.g. something timeless where our understanding evolves over time. If you're trying to teach people, I'd suggest introducing the two concepts independently, then showing the interplay with an example like the one you gave here.

I don't know if weird nested contexts can ever be really "intuitive". :D

What I've noticed about interviews is that there are a lot of generally unhappy and insecure people out there. People, especially in the Bay Area, are under the thumb at home and work and have a lot of debt and stressful family lives. Social comparison is an instinctual response in such instances and extreme bias is commonplace.

For the last 10+ years, I had TV service from my Internet access provider and three nice TV sets but NEVER watched TV, never turned on two of the TV sets, and used the third set only to watch VCR tapes of good movies. I had TV service from my ISP ONLY because getting all three of TV, Internet, and land line phone was cheaper than the other two and no TV.

I finally gave up on TV after looking, clicking and clicking on the remote control, for something worth watching and could never find it.

For NBA? Then the resolution was so low that the game just looked like a blur, and I could never learn anything about what plays, tactics, etc. the teams were using. Same for NFL -- just a blur with no insight into the pass patterns or pass defense. For the rest, just noise. So, I gave up.

Now my ISP gives me some TV over the Internet and for the first time in 10+ years I watched some, the most recent superbowl. Now the video technology, apparently some use of video cameras on drones, lots of replay, etc. made what was going on in the game at least a LITTLE meaningful. What I'd really like, from both the NFL and NBA would be game films with lots of slow motion, high resolution, and expert explanation -- as close to the most analytical information I could get. For the drama and which team to root for, I flatly, absolutely, positively do not care -- I care only about learning about strategy and tactics, say, as a coach, scout, general manager, etc. would. E.g., for the superbowl I watched, I came away with some understanding of the quarterbacks and pass receivers but NOTHING on the four lines, offensive, defensive, for the two teams. Soooo, for any good view, at LEAST also permit understanding the four lines. Etc.

But likely no more TV until, say, the next superbowl!
Definitely. The air is a universal medium... the ground is a mess.
I believe it is still used in the elementary school (ages 8 -12), there are even competitions in it in Croatia.

After Logo usually comes a language such as Pascal or Python - in my time, 15 years ago, it was Pascal but pretty soon my high school switched to Python.
Exactly.

It's my vague impression that you get species that can't interbreed after extended geographic/habitat isolation. But short of that, it's a tangled mess, with complex fertility patterns.
Haha, this mirrors my experience - once I was asked to write some embedded hardware driver, which required to run it under the RTOS in emulator, which they failed to run. They failed to run a simple qemu! I even provided them a shellscript to copy and run the required stuff. Surprisingly, I was hired nevertheless, because code "made sense", but still. I can imagine it's ubiquitous nowadays. Too many incompetent people decide on how to choose among competent people.

A computer. The PDP-11.

You have local information that cars don't yet know (but they probably will someday -- cars can send detailed road conditions to a central database, or they can communicate with other cars, so the car in front of you can say "watch out, there's a big pothole 8 inches from the left lane line" and your car will try to avoid it.

What do human drivers do there when they are unfamiliar with the road? Seems like the auto pilot should be able to do at least no worse than human drivers.
The chart corresponds pretty well with all the high profile exits over the last year (most of them now trading lower than what the last few rounds valued them at).
Honestly, I used to see a lot more abrasive jerks on the IRC of old.

Lots of RTFM and refusing to answer direct technical questions because "why would you want to do that?"

Some channels, like #politics on efnet were true cesspools.

In contrast, my later experience with FreeNode has been consistently helpful on virtually every channel I've been to, except for #paludis, which really was full of jerks. I've seen trolls maybe once every year or two on FreeNode and they've been swiftly dealt with, rarely to be seen again.

I guess your mileage will vary depending on which channels and networks you visit, though.
Interesting idea! Of course there are initiatives such as Google Summer of Code, but I haven't heard yet of a startup that has remote internships.
Although it would make sense if the whole company is remote.
The problem is that the way the phone system is currently set up, it is not possible to do this due diligence. That is what's being worked on.

Google would like their engineers to believe that, I'm sure, but I doubt it. A large company is just incompatible with the idea of being elite. "Regression to the mean" says that as Google adds engineers they will more closely resemble the general population of engineers.
The underlying point is true: Dems are not ready. The other point, that the author felt "the left" had failed them by hate and vituperation might or might not be true: I don't know, I don't follow the US politics well enough to be sure.

I do believe (and said so on the medium feedback) that the critical question is: do the Trump voters actually expect him to deliver? If not, its ideology, and so his failures don't matter. If they do expect him to "heal amerika" then they are in for a huge disappointment.
I think you mean you can't have same element redeclared? Then yes this is still the case, and at least for now it will be - for any library that can output custom elements. Every component is a real interactable HTML element, imagine <div> or <p> would work differently. I believe there is some work for multiple component registries but I'm not tracking the progress on that. This is HTML thing - it is not a library specific problem. It might get solved eventually https://github.com/w3c/webcomponents/issues/716.

I come from python world where you have same restriction for all packages so it never occured to me as a serious problem :) We just pin ranges in libraries. And application itself pins specific versions in place.
No. The emulated phone in this proposal is a way to run the Signal Android app.

During enrollment Signal uses SMS to close the loop on a claimed phone number. The OPs real phone doesn't run Android but it can receive SMS messages so it gets that SMS. The next screen in the emulated app says if the SMS code wasn't filled out automatically then please type it in, and that's what you do.

Tada, now your Signal account is linked to your quite real phone number for a dumb phone.
SS has long been used to mean "Super Sport" by GM.

I feel like it didn't used to have bad associations for virtually anybody, but like an unwanted immune reaction, first someone says it makes them uncomfortable, and then another person who is antagonized by everything being attacked as racist or fascist declares that they think it's fine, and then a third, possibly just a troublemaker, defends the person who thinks it's ok and associates it with fascism as if that should be positive.

1. Anything less than 100% FULL automation is MORE dangerous than manual driving, because the "driver" will almost certainly lack any situational awareness. When the need for manual intervention happen, it will be at the moments where you need maximum awareness and split second reflexes.

Airline pilots already face this -- it's hard to stay engaged in flying when the plane can fly itself. By the time something bad happens and the plane gives up and hands control back to the pilot, the pilot lacks the full situational awareness he would have had if he was flying the whole time.
There's a lot of junk. I imagine if you could name books or storyline games, etc...someone could recommend a few films with similar appeal.

Of the movies I like, "Shawshank Redemption" is often cited by others.

For an insight into that great man’s life, I highly recommend reading The Supermen: The Story of Seymour Cray and the Technical Wizards Behind the Supercomputer by Charles J. Murray. I remember reading it back when I was in high-school so it’s more than twenty years old by now, but it’s still an amazing account of how those amazing people built those stunning machines.

> There's absolutely zero evidence of "induced demand" for housing.

There absolutely is. Here's a great paper studying the effect of removing rent control in Cambridge, MA (https://economics.mit.edu/files/9760) which found that rent in non-rent controlled units went up as a result of the removal. The effect is similar to what GP stated -- gentrification causes a feedback loop that can affect all housing.

All said, it is very possible (and I subscribe to the idea) that the Bay Area would not suffer from much induced demand because people are in the area for the economic opportunity, not for local amenities.
