Why is Saudi Arabia Elon's enemy here? Perhaps it is the opposite, and the Saudis are the one's funding the whole going private operation in the first place?
If the general pattern holds of the electrical power market being like the natural gas market, just at much shorter time scales, then does this mean that we are going to see an increase in electrical power storage in the next few years? Companies have been making money by offering storage and pooling services in energy for quite awhile. It's just that storage has been more difficult from an economic and technical sense with electricity than with, say, natural gas.
I highly doubt it. For starters his wealth isn't liquid enough. He would need to give up shareholder control of Amazon or take on huge debt with his control of Amazon as collateral.
Agreed but its a weird transaction system that works better on windy days. :)
> In less than a 100 chars, you can generate truly random passwords.

The default RNG is not a CSPRNG:

> Python uses the Mersenne Twister as the core generator […] and [that generator] is completely unsuitable for cryptographic purposes.

These aren't "truly random passwords". Don't do this, use the generator included in a more … complete? mainstream? keyring program like LastPass. Or use a generator usable for cryptographic purposes.

Also, we get to see all the ways a language causes people to write code that just completely fails on any non-ASCII input:

> leftpad

With all the classic leftpad bugs:

In [4]: for s in ('asdf', '\N{PILE OF POO} asdf', 'e\N{COMBINING ACUTE ACCENT} asdf'): print(left_pad(s, 10))
asdf
asdf
é asdf

I am particularly unfond of leftpad as a token example of "look how easy this is" and the endless debates about "useless" dependencies that projects have, because the functions are so "simple". But they're only simple when you start removing essential complexity from the problem, and in doing so, introduce bugs.

> palindrome

In [6]: is_palindrome('e\N{COMBINING ACUTE ACCENT}')
Out[6]: False

Unclosed file handles.

I have coworkers who love copy/pasting code like this into real codebases, which is why this stuff sort of horrifies me.

Is showing a code snippet that would be buggy if it were what one would actually need actually worthwhile, just because it fits in a tweet? I care about how much code it takes to do something properly, sans-corner-cutting, in a given language.

> prettify JSON

( https://books.agiliq.com/projects/tweetable-python/en/latest... )

Interestingly, you can just pipe to json.tool:

<something that outputs JSON> | python -m json.tool

(There's also jq, which will additionally do syntax highlighting and is significantly shorter to type, so that's my usual go-to, but this is about Python specifically.)

> convert CSV to sqlite, several other examples

There's just nothing here.
Everything I find about this idea looks like pie-in-the-sky speculation and back-of-the-envelope estimates. As far as I can tell, nobody is making serious engineering proposals for this idea. IMHO, you are far too sanguine.
Read-it-later software seems surprisingly hard to monetize given how few are in the space. Pocket, Instapaper and Pinboard seem to be the only valid players.

The ability to facilitate "archiving a webpage" seems to be simple, but read-it-later software needs to be more than that to the modern internet user it seems.

It needs to;
+ Save video and images
+ Most people require a TTS service of sorts
+ Even more people want text-extraction (and boy-oh-boy this is hard)
+ Cross-platform apps & syncing

Where are the big costs here?
Is it;

1. Scale (Syncing all that multimedia must be expensive)
2. Talent (doubt it's this all the teams seem to be extremely small teams)
3. AI & Scraping development (Most services are poor in their offerings here, not sure its this)

I've been thinking about the space a LOT and started to try and develop some pieces of software that eventually I hope people will be able to stitch together into something great.

When i've observed problems like this before it seems that eventually a large open source project comes along and kills the markets chance of generating any money, and read-it-later services seem to fit in that fuzzily-defined-in-my-head-only market segment.
I've never used macos full time. But I'm a developer that's worked with Linux in a professional environment(full time) 12+ years, full time at home(15 years) and dual booted windows/Linux for 23. Linux works really well for me. I do have a windows vm I have for some music instruments software that doesn't work in wine. I'd much rather run a macos vm instead. Windows is so annoying to use. Every time I use it makes me appreciate Linux that much more. But anyways, Linux has largely been smooth sailing for me.
> I see a fair amount of real innovation, and they seem committed to reducing paper cuts.

If you care about privacy and control, Win10 introduces many, many paper cuts.
By my estimation, people take a magnitude longer time to get in and out of an Uber. For some reason that I assume is due to a perceived difference between taxis and gigcars: taxis will leave you there if you're not ready, and Uber has to wait for as long as you want to dilly-dally.
I'm hardly an advocate of the typical right-wing position that guns keep the government in check.

But I do foresee a situation where there's a clash between the well-fed police (who want to keep it that way) and the starving poor in the US. The inner city riots will not be an issue, most metro PDs have experienced and well equipped riot control departments.

It's the armed, rural uprisings that pose a threat. Think Cliven Bundy-types leading a group of protestors in sieges of government or office buildings.

The logical next step is devices (storage) which can arbitrage these prices and make a profit. Capitalism is a wonderful thing, especially when it’s helping make green energy more efficient.
Can someone please explain then why we are paying the highest prices in the continental US

Not until you tell us where you live, because I'm not going to backtrack by looking up which state has $0.28/kWh electricity. Though without that knowledge, I'm going to guess something something supply and demand.
Yes, I do!

When I built Caddy, I actually needed a web server that met my specific needs. It HAD to work well, and when the community jumped on board to contribute, I found out I wasn't the only one with those needs.

Now I'm writing a file backup service for consumers like my sister and brother but also developers like myself, because I want my family to be able to preserve our memories. Existing solutions just aren't satisfying for our needs. With generations of family history and photos and lifestyle potentially on the line, you bet I care that we get it right!

We're not using any flashy technologies to make them. Most of it's pretty boring. But it's SO satisfying to see it working.
That is true for git's definition of "history," but it is not helpful here. If I force-push a commit that was signed a year ago, then the signature does not cover the fact that master was just rolled back by a year (the signature does not cover the reflog, in git parlance). You have a valid signature of the previous version of history, and clients cannot tell that history was rolled back without authorization.

If I push a pull-request to master that wasn't approved to be on master (e.g., a maintainer did a build of "disable signature validation to narrow down why tests are failing", and signed that commit and pushed it to a PR with the intention of rejecting the PR), then I also have a valid and completely signed "history", and it probably isn't even a force-push to get it onto master.

Git commit signatures authenticate exactly one thing: that at some point, the holder of this PGP key committed this commit. They say nothing about the suitability or future suitability of that commit to be used for any purpose. They don't solve the problem Homebrew had here, and they cause other problems (like breaking rebases).

Git tag signatures are significantly more useful, since they include the name of the tag. So you're not vulnerable to the second attack, and you're mostly not vulnerable to the first since a client wouldn't intentionally request tag 1.0 after getting tag 1.5. But you still have the problem of the client knowing which tag is current, and frequent tagging isn't a great replacement for a workflow where you want people to follow master.
> over the next 7-12 years there will be countries banning petrol/diesel cars.

Even today you cannot go to downtown Lisbon with a car built in the early 2000s, and last week the city of Turin announced that they'll basically forbid vehicles with Euro3 engines or less from the city's streets (Turin being the birthplace of FIAT and also hosting a most wonderful car museum). The writing is on the wall.
> A language by itself is almost never useful, every language needs a killer app,

I don't understand why this myth is still around.

C++ never had a killer app to start its momentum.

Neither did Javascript. Nor Java really (or maybe applets, back in the days?).

Languages can succeed on technical merits alone if they come out at the right time and fix real problems that programmers experience on current mainstream languages.
I was assuming humans and self-driving cars both get revenue from riders, but don't get paid in between. And I'm interpreting utilization as the percentage of the time that riders are paying.
WebAssembly works pretty much like Javascript: it doesn't have any new platform APIs, browsers can execute it without special permissions, it can be retrieved from a web server, etc. Any planned lockdown of it would be just as easy to do with javascript.

If the role is "get the carbon, that was for hundreds of millions of yeas trapped in the crust, back to the atmosphere in just a hundred or so of years and perish," yes, we’re success up to now.

You're right that it's not a precise dupe, but the topics are almost identical and we shouldn't have two of these on the front page at the same time. So we have to decide which one.

The other article is more substantive, since it's based on at least some facts, and the thread is correspondingly better. This one, by contrast, is really just an announcement of a possible future announcement. So it seems clear the first URL should win. If and when they actually take steps to go private, there will certainly be much discussion on HN.

0.0001% of Sun energy output can give about 500000m/s^2 acceleration to a million tonne payload, if I'm not mistaken.
Yes, this is my understanding of the implementation.
It's not a matter of whether drone operators _can_ learn. It's more a matter of many of them _not_ learning. Why do firefighters still have trouble with drone operators running drones in areas where they are actively fighting fires? Not that all pilots are good about following the regulations all the time even though they should, but the consequences to the individual for not following FAA regulations as a private pilot are generally much higher than they are/should be for drone operators.
Negative energy prices have been a not uncommon occurrence in various places in the US and EU for a while. They are not necessarily a good thing. They occur due to a combination of how generating sources are managed/dispatched [1] and because of policies that make it possible for (some) generating facilities to still make a profit while bidding to provide electricity at a negative cost (literally paying the recipient to take the electricity). This is not necessarily a good thing and can actually lead to increased carbon footprints of our energy generation mix along with other not necessarily good outcomes [2].

you left out your state :-) I thought washington state was the state with most renewables. I pay about 12c per kwh.
What problem are you talking about? I'm not getting any problem from the article at all, except the structural (and well-known) problem of a lot of our power infrastructure being designed for more predictable output patterns than we have today.

It's fairly typical 'state of the industry' coverage, with no real surprises.
Good question. What is your expectation? I found a link that seems to suggest that people do want them (at about 2% of cars sold), maybe just not at the level you expect? They are typically more expensive to buy. People aren't good with long term cost benefit analysis.
https://www.hybridcars.com/june-2018-hybrid-cars-sales-dashb...
It depends on where. In the US there is a state to state variation. In California for example, after the Enron power crisis, the government guaranteed ROI for construction of new power plants. Also don't forget there other costs beyond generation (like transmission lines and other infrastructure.)
Bingo. It's incredibly condescending and straight-up ignorant to caricature non-voters as naively unaware of the goings on.

Personally I like to make it as clear as possible that I did not endorse the outcome of the election. And seeing how the press reports on third parties gives little option there.

But as I said my biggest concern is that having voted seems to warp people's minds. If they voted for the winner, they rationalize what's being done as in line with corresponding to what they wished for. And if they voted for the loser they get to tell themselves they fought the good fight, but that the other majority is responsible for the results.

I actually think the second largest factor to winning elections is getting wary voters to show up and vote against the incumbent party (with the first being the tendency to go with what one knows).

IMHO, "centrist" is the wrong way to look at it, but of course I'm imparting my own views here. Primarily people just want to be left alone, but they can be whipped into a fervor against an "other". So both parties' basic marketing spiel is freedom for their grass roots constituents' general pain points. But obviously what's ruining your freedom is that other group over there. So really we've got to stop them, and maybe even give them some of their own medicine.

Then when an election is won and it's time for action, of course the profitable ideas have legs - say, undermining the freedoms of the "other" in a way justifiable to the winners. Meanwhile rolling back the older policies would cut into someone's profit, is thus politically unpalatable, and therefore nothing gets done.
I just saw myself licking the thumb, putting the arm out of the window, waiting a bit and thinking "ok the thumb got chilled enough so it is great time to pay that bill".

I think we’ll start seeing a lot more formal verification or at least well tested software. Especially with the rise of drones, robotics, self driving cars etc making bugs much more harmful/deadly in a lot of places. I think for some of these cases the govt will actually step in like they have with aviation. This will make writing software a lot more bueracratic I imagine.
I've uninstalled Hangouts Dialer and Hangouts, reset stats and rebooted, left the phone untouched since. No change in discharge rate, it's still around 4-6% per hour. The top user wake lock offender is NlpWakeLock now, but it lasts just a second, but happens every 10-15 minutes.

Still event1 and event5 listed as wakesources with tens of thousands of counts per hour each. And still kernel wakeup reason "unknown" 12000+ counts per hour and 58m per hour duration (the entire 3h46m the phone was left since booting until capturing the bugreport).

The big gripe I have is in fact not the battery loss. It's the lack of tools that reliably pin the blame on the cause of the problem. So now I have to once again F around with uninstalling apps one by one to find out whodunnit and past experience tells me it will be a Google app or service with no recourse for getting the problem fixed. It's really an irritating platform.

Edit: And the WLD app shows the phone is "awake" 99% of the time. But if I put it in airplane mode, or wipe it and don't put it in airplane mode, it'll be awake 1% of the time (this is being left alone untouched for 1-4 hours).
Advanced and Simple Portfolio Tracking
I wonder about this as well. I think it’s time we start getting real answers from PG&E about why our power cost so much when apparently it’s so abundant.

Even with solar they charge me $10/month to be hooked into the grid, even though they’re using that same connection to sell my excess premium renewable energy to others.
Good way for them to hedge against a threat to their primary source of income.
> The project is simply missing someone familiar enough to configure Jenkins properly.

I would say that this is a specific case of the far more general one. Substitute "any small organization" for "the project" and substitute any configuration familiarity (i.e. Ops skill) for Jenkins configuration familiarity.

Even in "Devops" job postings for startups, when mentioning CI/CD tools like Jenkins, the main desire seems to be to hire someone who's more Dev than Ops, to create the code to run the CI/CD pipeline, with something like configuration or security a mere afterthough, if that.

I think that negative prices are prima facie evidence of a market economy not functioning "well".

Negative prices seem to me to be to be equivalent to fines for doing things that aren't socially useful. If they proliferate, that's a suggestion something is out of whack.

Business as usual. Profits over people
If Elon's tweet is motivated by a desire to stick it to the shorts, and he does not in fact have funding lined up to take Tesla public, he could (probably would) face a massive stock manipulation lawsuit that would bankrupt him, in addition to any SEC settlements which would likely result in him being banned from holding an executive or board position in any publicly traded company.
Also, doesn't facial recognition historically have worse accuracy with people of color?
I'm wondering about that as well. I don't see any other post about it and this is the official post from Tesla.
Inertial navigation is possible, but the sensors are fairly low quality for anything over a couple of dozens of feet.
Almost exact same setup for me GA-P35 + Snow Leopard running tri-boot (Linux, Windows, OSX). I reclaimed the OSX disk as a data-only partition as it became seriously unmaintainable in 10.7. FWIW I've not had any issues upgrading Linux or Windows at major releases.
Elon has just written an email to employees, also published on the site, explaining how he thinks going private would be good for Tesla and very generally how it could work.

It doesn’t appear to include any more specifics about where funding for the opt-in buyout would come from.

TSLA resumed trading just before closing bell and closed at $379.57 up 11% for the day.

How to use the fastest in-memory database as a docker clusters
Very well said, thanks for the clarification. I read through it several times and came away feeling two different ways about it simultaneously.

1) Like you said, I assumed this meant that they were installing themselves via the law instead of relying on the honor system. I think that's awesome news.
2) I don't trust them to act in the best interest of the masses when it comes to which uses they green light and which uses they shoot down. But that's 100% my opinion which is cynical in nature most of the time.

As long as the EPA uses this power for good, I'm all for it. I am skeptical about their motives though (which is entirely subjective).
How did Facebook identify that person? By e-mail address?
I don't truly understand this "problem". I understand storing the energy in batteries is currently very expensive economically and materially.

However I believe there are plenty of "goods" (irrespective of if they are bulk materials, or partially processed products) which have a high processing energy per volume ratio (this does not need to be recoverable stored energy).

Allow me to give an example: currently we have a drought in Belgium (or at least Flanders). We are not landlocked, there is plenty of water in the sea. Desalination is energy intensive. Instead of only looking at energy storage, why can't we increase the processing capacity (more desalination sites capable of working in parallel), and desalinate say sea water during the energy flood? I don't expect this to be an ideal real world example, only a pattern for identifying such examples: any product (could be composite parts, or bulk material) which is relatively compact and has some high energy per product volume processinng step. Just do the process (desalination, welding some part to another part...) when the sun shines, and store them for later.

Products with very high step energy density are good candidates for storing, and could help flatten daily variations, and perhaps even seasonal variations!

Now some companies would prefer avoiding risk if they don't have guaranteed orders far enough into the future, then perhaps there should be a market for insurance or loans, so that the company is encouraged to take the risk, instead of wasting the cheap energy...
