patejam··on Massive Comcast Outage Hits the US
Yeah I understand aerial lines carried by those large towers shown in that image, but utility poles that can get hit by trucks seems problematic. Partly for accidental incidents like a truck crash, but also partly because of how easily it can become an attack vector.

I guess the plus side is that utility pole lines are probably the easiest to fix when cut.

There are massively important fiber lines being hung from a utility pole?

patejam··on Cape Town could be the first city to run out of water
That's assuming pricing scales linearly.

More likely, it takes a flat-ish $x to maintain the infrastructure, and the reduced usage means they can't reach that minimum $x threshold.

patejam··on Parents now spend twice as much time with their children as 50 years ago
I don't have kids, and I'm still pretty young (23), but one of my favorite things to do as a kid was go camping with my family.

Have you thought about a "spontaneous" roadtrip and weekend camping trip somewhere with no reception?

patejam··on Apple scientists disclose self-driving car research
Is it fair to compare the US to Europe?

US has an extremely different driving culture than Europe. ~13500miles/year for the US; ~8000miles/year for Europe. ~800 cars per 1000 people in the US; ~550-600 per 1000 in Europe.

Also, a larger number of people in the US simply couldn't live life without a car. I'm sitting in my hometown, a mere hour drive away from the largest city in the US, and I'd have to walk 45min to the nearest food. Work would be a 10 mile bike ride each way. This is New Jersey, the most densely populated state in the US.

The seatbelt thing is just us being dumb though.

patejam··on Closest Temperate World Orbiting Quiet Star Discovered
For me, two reasons:

1. If we're already going to do the journey to a far off planet, it'd be nice if we didn't have to have a huge amount of infrastructure to stay alive on the planet.

2. I feel like one of the ultimate goals of space travel is to find other life. The only life we know is on Earth. Earth-like planets are a good place to start.

You just have to do a bit of work to filter out the crap from your timeline (unfollow/unfriending)

patejam··on Cruise's 3rd generation self-driving car
Your comments sound like a PR statement, what goods? How do you know how close they are?

Looks to me that they designed a mass-producible car outfitted with self-driving systems (which is very cool!). But they are only just starting to do employee testing. Waymo has been doing that for years.

I'm not sure why you think they're dead ends. Religion is often a lifelong thing and can be very beneficial for you and your community. Politics and history are important throughout your life. I hope I don't have to explain that one.

Revolving a good amount of your life around popular culture absolutely does not mean you don't have your own opinions. If everyone had the same opinion about characters on a show, then there wouldn't be much to talk about. Sure, not everyone is going to have their own opinion on if the latest P=NP paper has any legs to stand on, but who cares?

In addition, what's the difference between watching a high quality TV show or movie and reading a fiction book? Sure, the book may be longer and more detailed, but there are plenty of extremely high quality TV shows being produced now.

patejam··on I spent my career in tech, but wasn’t prepared for its effect on my kids
Do you see no benefit in knowing pop culture? It's hugely important for socializing in the real world, and socializing is one of the main points of life.

I'd even say I was stunted socially early on for not participating in much pop culture. Sports and music were important even all the way back in elementary school.

patejam··on Explaining Programming to Six-Year-Olds
But his approach is boorrinnggg. It's just like any other school lesson.

Throw some wheels and a motor on a board and create a simple abstract language:

drive()

stop()

turn()

wait()

Boom, now you have them programming and have a freaking robot moving around!

I don't think we should be starting out with even mentioning binary to college students in the intro class, let alone 6 year olds. How are either of them going to use that knowledge? The college kids will use it when they get to their assembler class...otherwise that's about it.

Messing around with a super abstracted language will give them the only thing they should get out of the lesson: you tell a computer what to do and it does it.

patejam··on Show HN: Anonymous interview evals of strong software/ML engineering candidates
Are you serious with your ideas for an interview? You have:

1. Someone running linux? What about gamers who dual boot or VM into linux? What about people using the new windows+ubuntu thing? What about people who do windows/android/whatever dev that can be done completely fine in windows?

2. Fine, but extremely easy. Not much more than a small filter

3. You don't expect an answer? What are you getting out of this?

4. What?

5. What? Why?

patejam··on 153k Ether Stolen in Parity Multi-Sig Attack
I feel like we shouldn't be expressed in dollars, but in percentage of total funds. In this case 16 million is about 1% of the total. This would be a $16 billion case if the US banking system was the target and used this technology.
patejam··on Thursday night Mountain View power outage the result of a drone crash
You can fly a plane into a restricted airspace and get off without criminal charges. It's completely unreasonable to expect a multi-decade sentence for something like this.

I also dislike drones around people (I'm a climber, and have had a drone fly by me while navigating rock 300' off the ground), but come on.

patejam··on Alex Honnold Scales El Capitan Without Ropes, and the Climbing World Reels
I think there's such a pushback on the term "cheating death" because it sounds like "I should have died, but I didn't", when in reality that's not what the thought process is. The thought process is "of course I'm not going to die because of x y and z".

For me, the best way to describe it is that I strive to feel in control in progressively more difficult environments. That's the mental state I'm looking for. The progression of the mental state goals are easy to follow:

Top Rope (rope already set up above you): "I feel in control despite me being 40' off the ground"

Lead climbing (bring the rope up and clip into the wall as you go): "I feel in control despite me having to take a big fall if I fail"

Outdoor climbing: "I feel control despite me climbing real cliffs outside"

And you can follow this all the way to free soloing, where you can feel in control despite having no safety net at all. I'm not going to pretend that I understand Honnold, and I don't free solo, but this line of thinking makes sense to me.

The other off topic reasons I climb are:

1. Getting better at a sport, just like any other sport/hobby.

2. I like the outdoors and adventure, climbing is a great way to see things from a perspective most can't.

3. Fitness

patejam··on Alex Honnold Scales El Capitan Without Ropes, and the Climbing World Reels
By far the best article I've seen to supplement this: https://www.outsideonline.com/2190306/why-alex-honnolds-free...

As a climber, there are very few people that I trust to have a more useful opinion on all this than Tommy Caldwell, a close friend and long time climbing partner of Honnold. It's so out there for most people that most jump to conclusions without proper knowledge of the subject.

Caldwell is in an interesting position of having to balance supporting his friend, and trying to get over the fact that he very well could die doing these attempts. His article does a great job expressing this.

patejam··on Moneyball teams
They're out on the ice the entire game, and usually the only person on the team that can play that position at any acceptable level. That on top of goalies being your last line of defense, having to take 25-35 shots per game.

The same reason your team fights a lot when the other team messes with your goalie; can't afford an injured goalie.

Even if they're taking huge risks going through a debris field, they're destroying the craft soon after anyway. If it actually is risky, it's probably worth the risk.

To be fair, which side companies take on international disputes (in this case a border) sometimes matters. e.g. all the craziness over Taiwan being part of China or not.
patejam··on Amex, Challenged by Chase, Is Losing the Snob War
>“I don’t think it would be American Express,” one diner said. “I feel like that would be braggy, like I’m trying to prove I’m a big shot.”

>Others nodded in agreement. “I’d probably use this,” said another, pulling out a blue-tinged credit card. “An Amex says you’re rich, but this says you’re interesting.”

Where did they find these people? When did using the CSR become a statement? Everyone I know got it for the free money, and uses whatever card gets the most points for whatever purchase.

patejam··on Two-part Rubik's algorithms
Under a minute when I was practicing. I'm sure it'd take me 2-3 minutes now.

My last algorithm switched the top right and top left edge pieces (as well as two corners which I'll ignore for this explanation). So I look as the top right edge and figure out where it needed to go to be solved, let's say the front left edge. Now if I move the front left edge to the top left, do my algorithm, and move it back, those pieces will be swapped.

Here's where it gets fun: since I know what was originally the front left edge is now going to be in the top right position, I can chain this together when memorizing. So memorizing would sound like "top right goes to front left which goes to back right which goes to..."

In practice this was just me pointing to pieces and visualizing everything. Another strategy is to assign a letter to each piece and remember a string of letters. At most the length of the string will be numEdges -1 + numCorners - 1 = 18.

And then once it's translated to letters you can use more traditional memorization techniques like Roman Rooms. This is how people can solve dozens of cubes at once blindfolded (I've only done three at a time).

patejam··on Two-part Rubik's algorithms
This is also how people can solve Rubik's Cubes blindfolded: use algorithms that only move a couple pieces without changing the rest of the state. It's suddenly way easier to keep track the state when only a few pieces are moving at a time.

When I was a speedcuber I could use three algorithms to solve a cube blindfolded after memorizing where each piece needed to go: one to flip two edges, one to rotate two corners, and one that switched two corners and two edges at the same time (T-perm for you cubers).

Then it was just 1. orient the edges and corners in a way that makes them easy to move around the cube and 2. move the pieces where they need to go.

This is a very rudimentary strategy, and there are MUCH faster ways to solve the cube, but this is all you need.

patejam··on Amazon imposes limit on reviews
I haven't had this experience at all. Prime ships in two days almost always. Same day prime does was it says. I've had refunds without having to ship back products, and when I did have to ship back a product (shoes) I got the refund right away and free return shipping like they advertised. I'm also in a major US metro area.

Prices don't seem too bad. My latest purchase was head and shoulders. Looked up the price at Walmart and it was 10 cents more expensive than Amazon. This is my experience for most home goods. For anything not home goods, they're certainly cheaper than any in-person store that I can think of.

I'm not sure which of our experiences is the outlier. One thing that might be different is that almost all my purchases are Prime shipping items.

patejam··on Infineon chip solves Rubik’s Cube in 637 milliseconds
You don't need "vision algorithms". Just average the color of a couple of pixels per square. The cube is always in the same place, no need to do anything fancy.
