Well, a class 8 trucks has a gross weight of over 33,000 pounds. Let's pretend that Musk gets that 1MWh by slapping some Powerwall 2 units on a truck frame.

The Powerwall 2 has a capacity of 200 kWh, costs $5,500 and weighs ~3,500 pounds. So we're looking at 17,500 pounds and $27,500 for that 1 MWh of batteries.

That's about half the minimum gross weight of the truck at a fairly reasonable price compared to the vehicle cost as a whole.

I'm sure there would some significant weight savings using a electric drive versus the large diesel engine + drivetrain. How much savings? I have no idea, but it should significantly cut into the battery weight penalty.

Edit: Looks like a typical heavy duty engine (Cummings ISX15) is only about 3,000 pounds, dry weight. The Model S electric motors are only 70 pounds, so let's say at least one Powerwall is "free" weight-wise.

Also, the ISX15 looks to be >$20,000 for rebuilt engine, so the battery costs look approximately comparable to a traditional engine price.
I've started having a coffee first and then working at my local public library - more outlets, more seating, more quiet, and faster wifi.
Sure, if you literally NEVER fill up. But that's a pretty iffy metric, because people will not cram themselves into every available seat; a party of 4 can come on, see no totally open tables, and bail, even if you have a few seats here and there.

Most of the country is not as expensive as San Francisco, and expenses are driven by labor and electricity. You can afford a few extra square feet to have enough seating when at peak capacity.
The problem with smoking sections was the smoke would waft over to the non-smoking area. You'll have the same problem with wifi.

Picasa was a pretty great app... as was desktop search widget thingy... I wish that Picasa/Photos were better integrated, and the interface were cleaned up like other MD apps from google... that said, Picasa was a great app for managing photos.
As someone who has always seen ancap stuff as a mix of bullshit and good intentions (and it's easy to correctly identify a flaw in the status quo while having only non- or counter-productive ideas about what to do instead), I'd like to know more from a former ancap…

Do you have any ELI5 about stuff like (A) whether there's anything interesting in ancap stuff or if it's just repeating the same simplistic dogma all the way down and (B) how to get ancap folks to recognize the validity of agnosticism (i.e. somehow get them to take the first step from blindly dogmatic to being able to express their ideology as interesting ideas they like but acknowledge that they can't actually know omnisciently that it aligns with reality…)
Perhaps you're not familiar with Intel's management engine?
It's Uncle Bob who says objects are bags of functions. And this is not specific to Smalltalk nor dynamic languages. In Java, C#, and C++, objects are still just bags of functions.

Bad trend for international travellers subject to data roaming fees that still cost dollars per megabyte (megabyte not gigabyte because it's 1995 once you cross a border).
No, I don't see it.

Disclaimer: I know a bunch of people -- friends, colleagues, neighbours etc that are Chinese/or of Chinese descent.

1. - they got here somehow -- was it hard?. No. They did not have to escape on a raft like Cuban exiles. They just left and noone bothered them.

2. - They seem to be communicating with their families in China with no issues. You know, SMS, email etc

3. - They also travel back and forth, this includes kids, parents, grandmas and grandpas.

Overall, the funny thing is that I never heard any of my friends/colleagues complain about China.

Meantime, CNN and Fox etc keep saying that China is like devil, except worse.

Guess who I trust.
$2/day ($0 if I don't use it on a particular day) for me in Australia (unlimited data but limited to 3g). Unfortunately, I don't think this plan is available anymore.

About to head to NZ and not looking forward to giving up this ideal (for me) prepaid plan.
I love stopping by there when I'm in SF.

Wonderful vibes - busy and friendly.
I think the wireless carriers may have just won, with 4G unlimited plans, who needs in-secure wide open wifi. Over the years in tech, I look for certain inflection points, and I think this could be one. Only time will tell, but it has that look to it for me.
I despise Safari.
If they just used Chromium, instead waiting years to merge in the improvements, my job would be so much less frustrating.

I have OSX in a VM just for Safari issues.
I'm sorry. If a Stanford grad gets the same job as a bootcamper, I fail to see the value of college.

It's not so much about marginalizing a job as much as an examination of the value of education from a good school.

Either education isn't valuable anymore or companies suck at allocating bright minds. You choose!
If you read the article this has nothing to do with their reasons for not offering wifi.
Perhaps because I'm new to this stuff, I enjoyed the writeup. I wonder if I'm out of place expecting a single run through of a-z 0-9 to determine the range of chars present in the password?

It turns out (due to repeated chars) to only have 14 unique chars. This single run through would have reduced the alphabet size (A, in the article) from 36 to 14. The 432 iterations becomes 168.

I'm sure there are other optimisations I'm missing!
I've always daydreamed about a cafe big enough to have two viable areas: one quiet and businesslike, where working on laptops is OK, and one buzzy and social, where working on laptops is forbidden. The idea that somehow it's completely wrong to do business in a cafe would come as a surprise to the coffeehouses that ultimately turned into Lloyd's of London and the London Stock Exchange, to name a couple.

In my daydream, there is somehow a way to make people pay for the space they are taking up, too. Perhaps what I'm thinking of is a co-working space with a cafe next door?
I don't know why this never occurred to me before now. I drive by a public library every time I go to a coffee shop or coworking space to work.

My first thought is, what's the ratio of those shows live vs. on-demand viewers? If you're looking at mostly live viewers, the time-slot the show is given could be the driver of the volume of eyeballs as much as the content.

In otherwords, perhaps their best watched shows are the ones in the worst decline / their best watched (i.e. tent pole shows) are bleeding the most viewers. I can't speak to the cause.
Right, but then the cap is generally a few GB per month anyhow
It's that way in Australia - and worse. You've got our pay TV provider doing silly things like [1] and something strange with the broadcast rights meaning I can't really stream all the games until 2020.

Cable/satellite isn't really as big in Australia as it is in the States and Canada, but the last time I looked it was still $30+ a month if you wanted sport in HD (you know, so you can actually see where the ball is)

Fair enough. I didn't mean to come across as arrogant; I just wasn't thinking about the audience. I'm happy you got value from it.

I disagree.

True, the average sportsfan only watches whole games of their favorite teams.

However, people love highlight reels. That's why Sportscenter is so huge.

Unfortunately, ESPN is moving more and more towards "personalities" and gossip and whatever. Just give me the highlights on loop. That way, bars, restaurants, people in their own homes will have it on in the background constantly.

EDIT: Sure, they need to do more content on the web and on-demand or whatever. But their core TV programming should be less TMZ-y. I don't care what athletes did on vacation.

This is a great question and should be an "Ask HN" feature.
The solution you've outlined here is Bleacher Report's _Team Stream_.

Show HN: Aggregator and chrome extension to resist Trump's agenda
And it's only going to get worse. The article notes that most of the 100 laid off were reporters and that ESPN was moving towards opinion. This is the beginning of the end for most sports fans, I'd imagine. I remember the days of being home in the morning from classes in the early 90s and seeing Australian Rules Football or a quality discussion of some sport on ESPN. Now it's Mike and Mike or some other inane uselessness.
It works to reduce the number of people who stay too long without directly attacking them. WiFi access might be a motivator for using the cafe this way even if it isn't the main reason people do it.
What was your degree in?
ESPN would be in trouble without pushing progressive politics. The business model simply isn't holding up. But alienating half of your consumers probably isn't the best way to deal with a failing business model.
Maybe they mean that the area would be designated for people who intend to sit and use the wifi for a long period, whereas the other area would be for shorter sits.
I don't know of any 'solution' to this (if one agrees it is something to be solved), though to deal with your inner voice, it's best to listen to it, and I think that meditation can be a good way to do that.

Sometimes I'm arguing on HN or imageboards etc. and I think that to wind down from it all, to realise the impermanence of it, it's good to meditate, noticing the thoughts that appear in your mind. No distractions, music etc.
So what is the crime of KIM of NK? Well NK has oil reserves exceeding saudi ( you can google this ), also NK has rare earth mineral reserves 2/3 of all known on earth REM is the vitamin of the high-tech world. China makes the IC's and NK has the vitamins that make them possible.

Kim wants to go slow, and he knows with the REM & OIL, NK can & will become the Singapore/Switzerland of Asia.

Trouble is the USA doesn't like SLOW, they want it all now, just like Libya and its low-sulfur oil back in the 1980's, when Raygun first targeted the destruction of Libya.

Lastly WRT to this OP, we know in the USA that mostly all that comes out of modernization is a police state. An agrarian NK means that most people don't even bother with their GOV, with technology comes Orwellian monitoring as can be seen now in USA all tech devices in the bathroom and bedroom always monitoring people.

If KIM has his way and NK is like Singapore, nobody is going to revolt, just like Brunei, everybody will be rich, fat, and happy.
Call it "laptop-section" and "no-laptop-section" and enforce that? (since it seems to be the goal in the end anyways) I've been to places like that and it works.
>This sends the alt-right sewers of the Internet and their minions at publications like the National Review into fits of hysterics.

Calling the National Review alt-right is an affront to the English language.
Yeah, "this one shop somewhere is doing <insert contrarian alarmism" doesn't cut it.
Interesting stuff.

Doesn't even the relatively small amount of latency introduced over RDP make things like video/audio editing difficult and dealing with things like audio sync impossible?

Or were/are they doing something where the actual video/files/apps are on the local machine, but any outside access is via RDP only?

With those kind of stringent controls, how do you think they could have gotten in?

I think directing funding away from things can be political. It is like saying, "we don't want this question answered." Directing funding towards answering certain questions isn't political in my mind, though.
I failed every coding interview as well. I'm not a great programmer - no industry experience, only academic, (but I passed all of the "coding riddle" problems my friend who is a senior programmer kept failing), and I made it through triplebyte's interview (I can write a bloom filter from scratch in under an hour). When whiteboarding though I have problems like, "doesn't default to hash", "has trouble remembering how to BFS", etc.

Eventually I got a programming job doing data science at a startup in "emergency hire mode". Didn't have to whiteboard, was hired on reputation and friend network alone. They even forgot to ask me to send a link to my GitHub. Most of my day to day in the first few weeks has been literally "debugging shellscript".
Yep, this has been a thing since the early 2000s, if not 90s.

Not sure about computer, but I'm installed this on every single phone I've had since my HTC Dream (very first android phone).

It honestly is the perfect "portable" game to kill 15m here or there. I've been playing it for over 8 years now and I still keep cycling through. And the controls on phones are pretty well made too.

I love almost all the games in the pack. That feeling you get when you solve your very first Sudoku, and then the next 10 when you slowly discovery new "strategies"? Well you can have that feeling many many times over with this! That's how I introduce this to people.
> building affordable apartments often requires finding "loopholes" and squeezing something through the regulatory process before it gets shut down.

No one is against affordable housing. But people are often so desperate for housing that they'll 'choose' to take unsafe / unsanitary / unlivable conditions, such as the tenements some people are pushing as a "solution" to housing. People having to resort to these conditions makes everyone's lives worse (both the residents, and the city with which these residents interact in).

This looks exactly like the "tragedy of the commons" the parent poster warned about, and a good use of regulation to prevent that abuse. For the same reason you can't sell a car without seatbelts and airbags, Seattle has prevented the new construction of tenements. That's a win for everyone. Real apartments will get built instead, ones that are still super small, but are actually safe and livable.
Would you consider Linda Cohn, who has anchored more SportsCenter editions than anybody in ESPN history [1], an "unserious" person?

You can concatenate dictionaries in Python:

Unless this is doing something unintended?

I applaud the bill for the security requirements but it seems to be lacking in privacy protections. Assuming this summary is accurate they've left out the provision that would give the bill real teeth. As it stands all this will do is add a screen that says, "accept the privacy policy to start using your device."

* The user must be given the option to refuse or withdraw consent at any time without penalty or loss of device functionality.

The burden must be place on the manufacturer to argue that data collection is necessary for the function of the device.

I really wanted to read that article, but it kept jumping back to the top of the page every 30 or so seconds. Plus, the bar at the top would randomly pop back down a couple seconds after I would scroll.
The C302 definitely looks interesting... have any experience with "corporate" vpn connections? When my last mbp was stolen, I used an earlier atom chromebook for nearly a year, but without VPN access (at the time) that worked, it wasn't great.

When I needed more, I could RDP, or SSH to something bigger... was nice light/small machine to have with me to stay connected. As it is, my current (2014 rmbp) sits mostly in the bag and rarely goes with me. My work issued one is tethered to the desk. Wouldn't mind a machine I care a little less about losing to have with me, or keep in the car even.

Also, how is the feel of the touchpad? I'm guessing newer builds/kernels should support docker now.
I used LaTeX for problem sets throughout grad school, although when I was done with coursework I switched over to Markdown for the dissertation. As long as you only plan to convert your Markdown to LaTeX, you can drop into LaTeX whenever you need more control. This requires knowing LaTeX really well however, which is why it was handy that I'd used it for my problem sets. The end product is really much better, and you do get much better at it with practice, particularly if you also learn a real text editor.
Maybe doing something that's actively harmful could be considered wasting time?
The taxes the King wanted to levy were relatively minor. The ruling class hypothesis doesn't explain why they would launch an expensive and dangerous revolution over a few minor taxes, nor does it explain the revolution's support from the people and intelligentsia. In fact, the rich and powerful tended Loyalist, and many of the top Revolutionaries weren't exactly landed gentry.

There's great danger in the Marxoid tendency to see everything in terms of economics and social class. Leaving aside its obvious failures in practical matters, this tendency discounts many real human emotions and often leads one to topsy-turvy assumptions compared to what actually happened.

Audits are hardly perfect, nor are they intended to be.

One could argue that the fact that a leak of this scope and scale hasn't happened before (OITNB is just one of possibly dozens of shows leaked) is evidence supporting that the policies and audits are working.

Maybe you aren't near water or writing performance-sensitive code 95% of the time, but the 5% of the time you're in over your head, being able to implement (or identify when to use) basic algorithms will save you a whole lot of time, money, and headache.
NASA 4D-print ‘space chain mail’ to protect astronauts from flying meteorites
I think that's a fair choice for a number of reasons. The problem is, the need for an external workspace still isn't going away. This is a /huge/ market opportunity, and anybody who has gone to Workshop Cafe in San Francisco knows it. (Just try to find a seat there during business hours; it's impossible.)

The problem with the coffee shop is that the value they provide and their financial model are not aligned. Coffee shops make money by selling coffee. Workers go to coffee shops for the workspace, location, and ambiance of not working from home. Yes, people also go to coffee shops to buy coffee, but I'm not talking about those people. There is a class of person (freelancers, artists, even people just taking the day off from their normal office) who want a non-lonely place to work around people.

The only business I've seen who "gets it" is Workshop Cafe -- a coffee shop that makes its money by selling the workspace, not the coffee (but yes they do also serve coffee). They have power outlets at every seat, incredible Wi-Fi, and charge $2 / hour (at least last time I was there) for a seat, and even have phone booths for calls.

There should be a Workshop Cafe in every major city on Earth. There's already a WeWork for the more permanent class of co-working; why is there not a "coffee shop" that focuses its business catering toward laptop hobos, and actually provides amenities for that use -- no more scrounging for power outlets, crappy Wi-Fi, nowhere to take a call, et cetera. Workshop Cafe in SF will even deliver food from local restaurants to your table!

Then, finally, we will have two types of businesses for these two completely separate use cases: coffee shop-style drop-in co-working spaces, for people who want to get work done in a productive environment, and coffee shops. For you know, people who just want to drink a cup of coffee.
Good and Bad Procrastination
Java and C# allow you to expose mutable fields, so objects are not strictly (or even ordinarily) just bags of functions.
Although the Intel CPUs have a CISC instruction set, internally they are converted to RISC like uOPS in the early instruction decode stage. So an CISC instruction that increments a memory location is converted into uOPs to load from memory into an internal register, increment of that register followed by a store to memory. These days, the uOPS are so powerful that they do the opposite at times like merge adjacent compare and branch instruction into one uOP.
Write it and they will come!

How did your daughter get interested in (the concept of) juice? Our two-year-old has never really expressed an interest, but then we don't keep juice at home and he doesn't get it elsewhere either. He's curious about things we drink that he doesn't get (I drank a bottle of root beer in front of him the other day, he was very confused and curious), but if we put milk in front of him he's got the thing he wants most of all and ignores our drinks entirely.
