There is much progress being made in decreasing the cost of EVs and cleaning up our grid by installing more solar and wind. There has been not nearly as much progress in the production of cheap cellulosic ethanol or fuel based on algae.

There are a lot of Exxon commercials talking about algae-based fuels, but in reality we are still just making our ethanol from corn (which most agree is not a good idea). Given the momentum behind EVs and their other benefits (lower maintenance costs, less noise, no emissions, etc.), I would rather my tax dollars go towards accelerating the push for electrification than push for a transition to biofuels.
It is quite clear from recent press reports that the vast majority of Waymo's 10M miles were logged with a safety driver, and some with an additional safety engineer, but the title talks about "Waymo's driverless cars".

So obviously, the adjective driverless no longer means without a driver.

The part about an additional remote operator is tongue in cheek.

What United is threatening to do is forward a clearly uncollectable debt to a collection agency. This is pretty much fraud at its finest - they know it's not supposed to be collectable. It doesn't matter if the collection agency comes after you - United is on the hook for having forwarded that debt in the first place.

Yes, in an ideal world, collection agencies would properly verify the debts they collect on, but they definitely can't be arsed to do that voluntarily without gov't regulation saying so (and this administration is unlikely to provide said regulation).
They never tried to stop it but they never fostered it either. It was just coincidentally easy to reverse engineer the code and install mods. But the interfaces were VERY brittle, and mods had very specific version requirements.

Official mod support (with an installer and an API) was on the dev roadmap but never materialized.
Attorney here! (Not providing legal advice, though.)

I agree that the Contract of Carriage is probably not the strongest basis by which United can demand recompense for abandoning a segment. Instead, I think they have a better chance of prevailing on a common-law fraud theory; see my explanation above.
I'd say it is normal. Generally you wouldn't find equations describing some proposed model, instead you would find "equations" describing the statistical observations. This paper, however, isn't empirical. It instead proposes a theoretical framework, based on the earlier studies. It argues (hopefully soundly) from the premises of the quoted studies to the conclusions it reaches. The point of the research isn't to present this is exactly how this behaves in mathematical terms, or even suggest a mathematical model for how it could work. Instead it presents a semi-formal description of how it could work, so someone can come up with an experiment trying to establish if it really does work that way. Once some evidence is obtained, you go from there to the more mathematical models.

Its hard to formalise things especially in fields were you're far removed from the maths. So rather than spending a ton of time making a model that is probably fundamentally wrong, you make an approximation in informal language. Scientific discovery is in my mind is always a balancing act between verifying propositions (which don't really _mean_ anything) and sharing thoughts (which don't really _prove_ anything).

In cognitive neuroscience semi-formal descriptions are great. In comp-sci, give me the equation already!

Not necessarily. Airlines have sophisticated yield management programs that should give them a good estimate on how many passengers are likely to skip the final leg of any particular route -- the airline can oversell the final leg by exactly the number of passengers who aren't likely to show up.
Credit isn't a measure of financial savvy. It's a measure of likelihood to repay debts. It may be financially savvy to strategically default, putting the two in conflict.
They will be creating stock to fund the purchase, so in essence, yes. The number of shares outstanding will rise by $2B (price) / $76 (Twilio price as of transaction agreement) = ~26M new shares of Twilio to Sendgrid owners.
Although if this becomes popular enough I can see the parsec team investing resources into their own browser.
They do however, have a pretty sturdy belief, that despite being paid for it, you won't be showing up for the return leg (in fact, they tell you that you will be forfeiting that return leg), so they can resell it.

In fact, they also threaten the right to cancel your entire return trip, not just the segment in question.
"I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the Earth", said Kennedy, and all the senators rushed the podium, slapped him on the back, and popped champagne, as they realized the hardest part was done.
Right from the end of that forum post:

>Inception V1 is a four year old architecture that Tesla is scaling to a degree that I imagine inceptions’s creators could not have expected. Indeed, I would guess that four years ago most people in the field would not have expected that scaling would work this well. Scaling computational power, training data, and industrial resources plays to Tesla’s strengths and involves less uncertainty than potentially more powerful but less mature techniques.
Girls raped at charity that protects girls from rape
It makes me wonder how the men who have the focus and discipline to get in to those positions of power have not learned the discipline of controlling their sexual urges.

I will suggest that a lot of powerful men are only just now in recent years beginning to see women "in their league." It's highly problematic for them to respond to that with propositioning these women, but it's possibly not entirely fair to say they simply haven't learned to control themselves.

In some cases, they may control themselves just fine most of the time. Then they meet some very happening lady who blows them away under circumstances where they aren't used to seeing women at all and they find themselves in new territory they aren't entirely prepared for.

FWIW, I happen to be a woman. No, this is not an "apologist" position. This is my framing for how to navigate the social/business landscape without stuff blowing up in my face.
I mean, learning X is an opportunity cost. Not dismissing your answer, but I guess we could rephrase the question: "Is Rails worth learning instead of X", where X can be some other popular frameworks. Or said differently, both for newcomers or more experienced devs, why do you think Rails is worth learning instead of some other web framework?
I see the free charging spaces at my local Target packed full of cars. I was wondering who would have time to spend there all the time until I realized some of them are Uber drivers. They get electric cars so they can charge for free waiting for their next customers. I'm guessing Target was hoping they would be actual customers who you drop by to shop while charging. I'm sure some time in the future they will be changed to have a fee once EVs become more common place.
> groovy, scala, clojure, and kotlin injected some cool ideas, but might have done more harm by cannibalizing the community and proving that just because it runs on the JVM doesn't make it great

1. Apache Groovy gave people closures and builders on the JVM but at the cost of static type checking, and developers happily embraced it.

2. Then Scala came along and showed you could have closures without losing the static type checking, so many developers moved there instead.

3. Then Clojure came and brought closures to the JVM and lost the syntax, but no-one embraced it.

4. Then Kotlin came and showed you could have both closures and builders on the JVM without losing the static typing, and it's now everyone's favorite.

5. Finally, Java bolted on closures and Groovy and Clojure bolted on static typing annotations, but who's using them?

The issue is it's also more expensive than using electric cars.
Wow. Really going for a trigger with the title.(you should get a lot of activity)

The answer that you will unconditionally see to this question will be "it depends"... I would get more specific with your question so that you can extract a bit of wisdom from the answers.

Rails is and has been a dominant web framework for the last ~10 years, dhh and the people working on it have crafted a wonderfully useful tool, with all sorts of lessons hidden inside the code. Ruby is a great language... and all of these things provide wonderful reasons to learn it.

With that being said, I don't use it anymore. and I'm not going to ever go back to it unless there something out of my control. ¯\_(ツ)_/¯

Do I recommend it? ... It depends
Exactly. I've owned a Tesla for 3 years. Never once have I used those retail parking lot chargers. They seem silly to me.

I charge in my garage, which doesn't need to be very fast at all, about 10Kw. And use the Supercharger network only on road trips.
OK, it's a dtrace thing that got ported to FreeBSD with dtrace. That still doesn't make it "Unix" any more than Linux's proc access.

Embddeding debugging information in a way that allows to you to use it (ie. in a way that you'd care about the format as an end user) implies giving you kernel addresses, which implies an ASLR bypass. If it's an implementation detail, then DWARF works great.

That's a little simplistic. The state of the carbon is incredibly important - keeping it locked in a tree, ice or the ground instead of floating around in the atmosphere is kind of the entire goal.

Heating with wood unlocks all that essentially inert carbon into wide spread particulate, so it's no more carbon neutral than burning coal you collect by hand. You're also depleting the carbon absorption side by harvesting the tree
That wasn't a question nor does anyone think you shouldn't try to prevent security flaws. The fact is it wont happen because of the way these systems are built within the car.

Ask HN: End-to-end encrypted online spreadsheet tool
I'm trying to identify end-to-end encrypted alternatives to the tools used by an NGO I work with that deals with sensitive data.

Tools for cloud storage ([Tresorit](https://tresorit.com/)), email ([Protonmail](https://protonmail.com/)), instant-messaging ([Signal](https://signal.org/)), collaborative text documents ([CryptPad](https://cryptpad.fr/)), collaboration between teams ([Keybase](https://keybase.io/)), hard drive encryption ([VeraCrypt](https://veracrypt.fr/)) abound, they're free, easy to use, secure, and overall amazing.

The one obstacle I haven't been able to tackle in several days of searching is an alternative to Google Sheets, a secure online spreadsheet with end-to-end encryption and collaborative editing, like what CryptPad (https://cryptpad.fr/) does for Google Docs.

Is there a ready-made alternative, or do I need to build a custom solution?
Numenta also put out a video recently explaining this new theory https://www.youtube.com/watch?v=LNRZD9YJCdI

I haven't read the details but not entirely. They will likely dilute their own outstanding shares by adding the required shares needed to acquire the company at that value. This will lower the total ownership as a percentage that each share represents but now every share owns more stuff.

So yes they are creating new shares making every other share worth less but it isn't a direct transfer of existing shares. You'll notice companies get board approval for setting aside a number of theoretical shares they could create if they wanted to for things like this or secondary offerings, etc.
One of the examples that coldnose offers has a suffix appended to it, so I think you're incorrect, too.

Maybe affixes?

By the way, yours is an example of Muphry's law. See https://en.wikipedia.org/wiki/Muphry%27s_law

And because I'm correcting your incorrect correction, I have a feeling that I've gotten something wrong, too.
Most likely this will be done by issuing new equity. The press release states that they will exchange Twilio Class A common stock per share of SendGrid common stock. They defined the exchange ratio (that's why the price is ~$2B and not a specific number) and will issue as many shares as they need to based on that ratio:

> 0.485 shares of Twilio Class A common stock per share of SendGrid common stock

Technically, issuing new shares dilutes every existing shareholders' ownership. But, if the market deems this to be an intelligent combination that was valued correctly, the market cap of the combined company should be ~$9.4B or (ideally) more. So the goal is for existing shareholders to hold, at worst, the same amount of value in dollar terms as before or, at best, hold more value as a result of the acquisition.
It’s just terminology from acting. Wouldn’t read too much into it. Getting annoyed by that is like being upset you have a team in your org called HR. “Human Resources? Am I just a unit of raw material to be put through the factory?!”
> Given that there are responses which declined to report anyone, the actual number is obviously higher.

I don't think you can assume that. I think it's very likely that the number is higher, but it's also possible that it's lower - that women who have experienced harassment are more likely to complete a survey on the topic than women who have not.
Because the marketing platform is terrible. Frequent need for a full page reload to fix a caching issue. Test emails don't support email template tags without a default value. Searching for an email address is terrible slow, the upload is glitchy. Email activity is also slow and limited, sometimes I don't even know if I hit enter because I have to wait so long with no UI indicators. The pricing is also horrible with no way to purge bounce or unsubscribed emails, so they just collect and drive up your "Contact Storage" fees. The recent Sender Authentication change created unreadable sub-domains until they started to offer an advanced option again.

Yes, I emailed support about a few issues but received the blanket "What browser are you using?" when I provided full details. So I built a marketing system on top of their API and fixed those issues for our users.
Precisely. "Potential revenue" is not a dishonored debt.

The article is informative. It seems the requirements are only for banks that have a presence in the US. I'm not sure if the bank I went to has a presence in the US. But I can see the Pakistani government simply giving a blanket "No".
If it's one woman who stands out in complaining about harassment, then maybe you have an argument. But you have to believe that a giant chunk of the female population are oversensitive and have siege mentalities in order to actually make a counterpoint to the study.

Do you actually believe that many women are oversensitive to harassment?
They've raised the relinquishment fee - i.e. the fee to get the State department to evaluate the relinquishment and issue a Certificate of Loss of Nationality - to match the renunciation fee.

For this conversation the difference is therefore mostly moot, even if a few minor differences still remain in the consequences.
> Facebook should have also designed their auth system more carefully, but that's a separate issue.

It's not a separate issue, though. One of the main ways they could have been more careful in designing their auth system was by choosing mechanisms that didn't create "legitimate purposes" for additional data collection in the first place.

This is a recurring theme in every data breach story that comes up. Every thread has someone correctly making the point that the company's business model requires them to store the leaked data, but this is not an excuse. Pick a more ethical business model.
Yes, there's definitely more to be done. Electric cars go hand in hand with moving to renewable electricity sources as well. It's easier to change what's on the other end of the grid than it is to stick solar panels, wind turbines, and nuclear reactors on cars.

I see the "well your electric car is just burning coal/oil/gas anyway" argument repeated pretty often despite being an oversimplification and usually wrong.
peak oil is not worth worrying about. I've studied this for investment projects and the whole idea is just a perpetual, simplistic, political meme that has existed since the oil industry started a century and a half ago. Oil might get more expensive than it is now, but that will lead rapidly to renewed investment in exploration and extraction. There are centuries-worth of reasonably-extractable oil - supply will literally never be a problem because we will have to leave that oil, and the coal, unburned for atmospheric chemistry reasons. peak oil consumption is a policy choice, peak oil supply is a myth.
But it was the hardest part wasn’t it? Nobody since then managed to get that commitment for a space program.

All the D-PRIVE options fix this.

A Firefox Nightly can be configured to do D-PRIVE (specifically DNS-over-HTTPS to Cloudflare) and do eSNI, and thus connect to a default configured Cloudflare site without any indication to other parties about which one...

Some other cloud providers or CDNs have made interested noises, if those noises weren't just for the public record they might begin doing the exact same thing in short order, especially if the Firefox tests go well.
Large agriculture has been an ecological disaster for decades. Pesticides, fertilizer runoff, heavy usage of herbicides, water mismanagement and foolish introductions of non-native species to counteract invasive pests making situations worse.

Can't happen in a tesla, “so even if somebody would gain access to the car, they cannot gain access to the powertrain or to the braking system.”

And how is this any different than we'll kill you in 24h if you dont pay?
Hi Clinton,

Author of edX here. At the time I left edX, the vast majority of courses used long videos and multiple choice questions.
Now that is an interesting idea for sure. So the more anonymity the more costly?
Precisely. In many ways it is better to steadily use a card (while being mindful of utilization ratios) and pay it than it is to carry a zero balance.

The credit system might have been initially about debt repayment, but there are several measures in store regarding "how valuable / revenue-generating is a customer".

And at times, these two principles may be in harmony, and at others, not so much.
Curious as to whether you have found a better Rails-type framework or have moved on to a different type of dev work that you prefer. Any recommendations?

If United Airlines decided to assess what they later define as the fair market price of the tickets thrown away, none of these bullet points would apply.

If you rent a car or motel room and you smoke in it, for example, they can charge you a fee. Keep your rental truck an extra day, they can charge you a fee. If you rent a Uber or Lyft and puke in it, for example, they can charge you a fee.

The FCRA is completely irrelevant to the topic here, because it's inapplicable to the above examples and United would argue they are similarly not violating it.

I wish this forum would allow people the option to disagree with an argument without censoring it. I respect (and even eagerly await) that others might disagree with my opinions, but that deserves a downvote less than an off-topic or rude post.
