Where in SF do we have shit tons of land? Building high volume transit would take a lot of land -- the entire BART system is constrained by how fast people can load/unload at Embarcadero station. The signaling system could push more trains through the tunnel, but the station can't handle more. The solution to that is to build more platforms. It'd be easy to do that with a ground level station or a shallow cut-and-cover station, but now it'd take digging out a huge cavern 50 feet underground while avoiding existing building basements and support pilings.

BART plans a billion dollar bandaid by digging out the other side of the station to allow boarding from both sides of the tunnel. But that billion dollars doesn't buy any additional tracks, just an extra exit from the sides of the trains.

Even the new 6+ billion dollar transit center is only going to have 3 platforms and 6 tracks for Caltrain and HSR. In comparison, Penn Station has 11 platforms & 21 tracks.
Isn't that just disguised NIMBYism though? Extreme permit costs, favors/bribes that make the threshold to action on building new housing higher?
First of all, most messaging platforms today are encrypted, so that rfc wouldn't really apply except to monitoring by the company providing the service, and that's the price you pay for "free stuff on the internet".

Second, almost all the "attackers" are nation-states and your ISP. If it's illegal to read your mail, it should be illegal to read your email (simple regulatory fix). That just leaves spy organizations, and nobody but computer geeks and privacy nutjobs cares about that.
Finishing costs are cheap. Builders do this to command a higher selling price.
"Seattle's 83 sq miles of land, at the midrise levels of central Paris, would accommodate 4.6M people, 25% more than the entire 8000 sq mile metro region currently houses."

Exactly, which is why there is zero mystery here. This is an entirely artificial, legal challenge. We already know what happens if we let cities develop organically, because we've already built places like Brooklyn and Queens.
It explains it, thanks. It’s a deal breaker for me so if I could I would go back to 8plus.
I don't think as many people would want to move to the Bay Area is they were forced to either buy a home or rent municipal owned housing.
Actually, it is “sound, complete, consistent, recursively axiomatizable: pick three”.
You hit the nail on the head.

Oren Etzioni has been shouting about the knowledge representation for years (full disclosure: this is something I'm focused on, too).
Yeah, these were some core, widely used packages that were deleted. If they were temporarily hijacked, lots of dev machines (including mine) may have been compromised. There’s a major security risk here, if there was any hijacking now is not the timing for information hiding and PR.
I should have added, "what cryptocurrencies are to fintech". Is it better :) ?
I was watching one of those engineering disaster shows and thought it would make a good name for a project. I didn't find any other software projects using the name, and it seemed like it would have decent googleability. The relationship to fire/explosions has given good themes for logos and sub-project names (like scorch).
Oh wow, nice.

There appear to be no decent photos of this thing on the internet, btw.
> because we've already built places like Brooklyn and Queens.

But then with NYC densities would NYC prices follow? Put it this way, do we have examples where higher densities didn't lead to unexpected higher prices due to critical population mass being achieved?
There are commercially-produced flashlights that use SMPS and continuous dimming. As they're all managed by microcontrollers, I'm sure it's actually hundreds or thousands of discrete steps.

> At some point I'll find out why LEDs need constant current.

There are flashlights that work by connecting a Li-ion battery to an LED through a FET that can use PWM to dim it. This will deliver all the power the battery is capable of providing at a given point on the LED's forward voltage curve. If that sounds like a good way to burn out components, it... can be. Everything needs to be fairly robust.

These flashlights do not have constant brightness. Even in lower modes, output tracks battery voltage. Strictly speaking, however, it demonstrates that it's possible to operate LEDs without constant current. Forward voltage drops a bit as temperature increases though, so LEDs are "greedy" and will essentially take all the current available as long as there's sufficient voltage. At some point, this will let the magic smoke out.

FET drivers in flashlights only work because the voltage range of the battery and LED overlap, battery voltage sags when it gets a heavy load on it, and some LEDs can handle a lot more current than the datasheet says for a few minutes at a time. None of these things are valid for mains-powered lighting, except that with sufficient heatsinking, many LEDs can be overdriven at a modest cost to longevity.
Actually I'm doing him a favor ... I completely understand that people talk like that within companies. When emotions are involved, that's what happens. When you're acting in any capacity as a spokesperson for a company (or I guess a government or non-profit too), a bit more decorum is called for. It's not just him - I've been feeling this for a long time. One thing I appreciated about Obama was that he was always dignified (not that I always agreed with what he was saying). Now that the POTUS posts uncouth tweets, maybe it's okay to put statements like that in your SEC filings too.

I got down-voted for calling out some of Kalanick's frat-boy behavior and speech. I'm sure it's not popular on a site predominated by twenty-somethings but since I'm old, I'd prefer to be called old-fashioned or out-of-touch rather than simply being dismissed. If it helps ... I'm sorry that I was so blunt - I should have typed these couple of paragraphs instead.
Does anybody know if there is an equivalent to Hidden Volumes for an OS? It would be pretty cool if you could give a password for your machine that loads up a default OS installation, or maybe some configurable fake user to make things look more 'legit'.
Neat! It would be cool to port this to one of the node option-parsing libraries, perhaps launching a small Electron-ish webapp for the "gooey."
For sure, but the disparity between median income and home price in SFBA is much greater.

Efficiency tends to decrease with current. It is rarely more efficient to run higher current and PWM than to simply run lower current.

It is, however often easier in terms of circuit design.
Ironically now that it is known that the major vulnerabilities found have to do with processor features that have probably been the most protected IP in the entire design.

I'd argue that for most applications fab isn't really all that relevant as a secret sauce. For any consumer device the benefit of an open core and a custom SoC that includes the CPU and other key parts will likely be acceptable even with 5 year old fab technology.
> Sorry cities, you can't have it both ways - can't demand more of developers and lower prices.

They (the people in charge of cities like Mountain View) mostly don't want it both ways, they'd rather have the status quo go on, which is why they throw up these requirements in the first place.
From what I've read in the past (and this is borne out by the article you've linked), you wouldn't necessarily use AKS if you need determinism, because there are other deterministic algorithms with worse asymptotics that perform better on smaller inputs. Has this changed in the last several years?

From Wikipedia

> While the algorithm is of immense theoretical importance, it is not used in practice. For 64-bit inputs, the Baillie–PSW primality test is deterministic and runs many orders of magnitude faster. For larger inputs, the performance of the (also unconditionally correct) ECPP and APR tests is far superior to AKS. Additionally, ECPP can output a primality certificate that allows independent and rapid verification of the results, which is not possible with the AKS algorithm.

The price per square foot with the exact same materials, finishes, construction quality, etc - not including cost of land - is 1/5 or less in a state like IN, MS, WI, MN, etc than CA, WA, OR, why is that?

I agree with you on everything here except for your "don't use email" point in the followups. For 99+% of people, being able to recover your archive when you forget your password or lose your device is more valuable than being secure against a state-level adversary.

I think the security debate around email suffers from an over-supply of confidentiality absolutists, in which both integrity and availability take the back seat to defense (or the theatre of defense) against a very narrow set of attacks.

Then you would also have to live in Mississippi, and getting a job isn't as easy either (even making median) because the place isn't exactly overflowing with non-minimum wage opportunity. If it wasn't for my dad's skills as a nuclear technician, we would have never lived there (BTW, if you want cheap housing and high salaries, go into nuclear power, they mostly built nuclear power plants where no one wants to live).
You know, back in the "old days", we used to host packages on these sites called "mirrors", so when one went down, we could get the package from another, and verify authenticity using multiple sources and signed files. There would be hundreds of mirrors for one set of files.

Kind of funny how shitty modern technology is. But I heard a quote recently that kind of explains it: "The more sophisticated something is, the easier it is to break it."
It's not a "middlebrow dismissal", it's a well reasoned argument about why this whole area of work is doomed to failure for structural reasons which can't be solved.

I don't see the business world adopting "serious" secure messengers anytime soon. People don't want to send business stuff over WhatsApp, so we'll have to "bother" with email a couple decades longer.

But I really hate that I can't encrypt business communication, like invoices or contracts, without resorting to encrypted.zip. What's wrong with fixing that situation?
After being installed on the new body, does the face look like the donor did or is it changed? I would imagine the new bone structure would change it at least a bit.

Would the recipient of the face be able to unlock the donor's iphone with it? So many questions.
I'd ask that in its reverse formulation too: if density is the answer, why is affordability in the US roughly inversely proportional to density?

Induced demand, or something with a similar effect, seems to apply to housing at least as much as it does to traffic.

And before we dismiss it entirely as "coasts are more desirable than landlocked middle America," let's take a look at both various coastal cities of varying density in California[0] and various less-desirable (Houston is technically coastal, I suppose, but not in the "good weather" or "pleasant" way) Texas[1]. San Diego is cheaper than SF or LA, but also much less dense. Fort Worth is cheaper than Dallas, but also much less dense, and pretty much right next door in the middle of a bunch of flat land.

Maybe we should start knocking down a bunch of non-affordable housing, run off the people with enough money to move away, and watch that affordability go up? ;)

That's also about what it costs to raise a house up. I guess with this you're losing a known (and importantly still insurable) quantity constructionwise + not having stuff fall off your shelves in a swell for being at street-ish level most of the time with this floating business. I guess if my house were prone to significant submersion I'd look into it vs always being 10 feet up, but I've also always wanted to live on a boat, so...
Not to mention much taxes, particularly the state income tax.
That exists and it’s called BART
> If someone cannot handle themselves, maybe they shouldn't be given a subsidized unit in a fancy expensive city

You need to solve the problem with your plan where the person who gets labelled "cannot handle themselves" is diverted into an isolated setting with much less stimulation/opportunity. You did say you weren't proposing to "ship" "addicts" to Alaska/Wyoming but there's a much higher level of responsibility than that -- you mustn't write them off / throw them on the scrap heap / set them up for an isolated dependent life by your own standards. It could be you one day.
That’s a good point. Call it 50 kHz to deal with people who have abnormal hearing response.
Video service is special because it is expensive on account of video files being large. You’re pulling a lot of bandwidth off Archive when you embed HTML5 onto your site. On its face, that’s a pretty shitty thing to leech from a charitable organization; YouTube pays for that with advertising. Archive takes donations. Are you donating?

I’m confused that you think this isn’t relevant. You’re directly advocating hotlinking against Archive and you don’t even mention supporting their operation in the slightest. I have no idea what you think I said, because your reply makes little sense.

> but email doesn't even have the basic mechanisms HTTP has to prevent secrets from accidentally being sent in the clear.

There is a draft standard [1] for strict transport security. I'm not sure of its current status though.

> Email leaks metadata. In fact, some of what we call email "metadata" isn't even metadata --- stuff like subject lines are simply content. They're sent in plaintext.

Nothing sent during the data phase of the SMTP transaction has to strictly be unencrypted. There's nothing preventing the client from encrypting both the headers and body of the message. But that doesn't prevent the MTA itself from adding uncrypted headers to the message after the client sends the CRLF.CRLF sequence to end the data phase.

> Most email users get their email from a website. Unless you make them install something on all their computers

I'm not sure how many users still use a dedicated email client, but I'm sure that there are many who use clients like Outlook, Apple Mail, Thunderbird, amongst others. Anyone who wants to encrypt their email needs to know they need to use a client on their machine that handles the encryption/decryption steps for them (or that they need to do it themselves.

MV real estate is so messed up that people from Google can barely afford it. Why the hell don't companies move to a more affordable place?
The best way to increase worker's income, reduce housing costs and eliminate all the ridiculous laws around housing regulation and property taxes is to replace sales tax and prop taxes for land value taxes.

As soon as the political gain to block construction dissapears, developing anything will be much cheaper and changes into policy will come with popular demand both by renters and landlords.
Technologists value "good", not "new." Sifting through all the "new" to find "better" is fun, so long as expectations are properly tempered.

Here’s how I’m harvesting credit card numbers and passwords from your site
> if density is the answer, why is affordability in the US roughly inversely proportional to density?

Because affordability is inversely proportional to demand, and higher-demand areas tend to have more dense housing.
Check out this video explaining why you can buy new detached homes in Tokyo for about 300k usd.

* Land owners have an absolute right to develop their own land - neighbors can't block you.
* You can build a 60 m^2 x 3 floor house on 100m^2 of land, or more.

So basically they build way denser, and reduce opportunities to block/rentseek.
I disagree, while also agreeing that IMAPS/SMTP-with-TLS is a huge improvement.

The big difference between HTTPS and SMTP is that there's an implicit extra hop. I go to send you an email. I connect to my outgoing mail server over SMTP-with-TLS, and anyone monitoring my connection cannot see the content of the message. Awesome! Likewise, you retrieve the message using IMAPS, and anyone monitoring your connect cannot see the content. Great!

But in between, there's absolutely no guarantee that my email provider sent it to your email provider over SMTP-with-TLS. It could very well have traveled completely cleartext, at which point it was harvested and archived by the NSA, with neither of our email providers having handed it over to them.
9) The remote bash startup order is further complicated by the existence of a compile time flag SSH_SOURCE_BASHRC. This flag determines if a remote non-interactive shell will load the ~/.bashrc file.

This flag is turned off by default and stays off in some distributions (like Archlinux), but is turned on in others (Debian, Fedora, ...) to replicate very old rsh behaviour.
Right. And more dense areas draw more business which draws more people which draws more business and also increases price more and more... so density isn't a cure by itself, it's part of the cycle that causes the problem we're trying to fix.

The same way "add another lane to the highway" doesn't fix traffic.

Life expectancy is a very blunt tool when measuring citizen's well being.

A few ways life expectancy can go down:

- babies that other would have died and not counted live long enough with modern medicine that they drag the average down

- refugees or immigrants in poor health increase, dragging the average down

- a change in methodology in how life expectancy is calculated
I can't speak for PyPI, but I know Ruby gems has had vulnerabilities in the past. A quick DuckDuckGo will probably suffice to demonstrate that. I'm not saying NPM is a great system, but it does seem to me that most systems have flaws, and any system that is as heavily used as NPM is likely to have them surface faster than other systems.
The reason is most likely because they saw this on the front-page: https://news.ycombinator.com/item?id=16085873. I've noticed that people like to submit items that are tangentially related to those that popup on the front page.
