>Are there things that we can't test that do exist?

There's many reasons to believe that objects that exit our light cone continue to exist after they do, even though they could never have any future interaction with us to confirm that. (Say a spaceship leaves Earth at near the speed of light in a straight line, and then enough time passes that the space between the ship and Earth is expanding so fast that the spaceship or any kind of signal from the spaceship would have to travel faster than light to return to Earth, which is impossible. Believing that the spaceship disappears when it exits our light cone requires believing in unnecessarily more complicated physics.)
It’s about staff and focus.

Right now we have 3 sysadmins for our own DC, and they can’t keep up with all the maintenance (upgrades on infra are the worst. Software quality on switches/SANs/appliances is terrifying. And those are better than quality of Server management, BIOS, etc. Even VMware has caused lots of pain with patches and upgrades in recent years.

If you don’t ever patch/upgrade to fix all the security vulnerabilities that exist at the infrastructure layer maybe “do it yourself” is cheaper. But that doesn’t fly in the banking industry.

We’re half-in the cloud and moving more there just to keep our head above water. We’re spending way less on cloud services than the $500K/year it would cost to double our infrastructure staff and keep it all in house.

The thing is, though, small differences in daily spending do matter, when summed over your adult life, and can make a meaningful difference in when (or whether) you can retire, especially if your savings rate is near zero. But sure, if you're tossing away thousands at a time for fun, then you've probably got some lower hanging fruit you can cut than saving a bit at Costco.
Goodbye nickels and dimes too I'd say. Might as well just do it all at once and simplify things for a good long time.
> It makes things easier to reason about for most day to day problems.

Careful! Tools that are easy for a trained expert to use and tools that are easy for a newbie to grasp are not only different sets of things — I'd go as far as to say that overlap between the two is very rare indeed.
I'm trying to not phrase this in a dick way, but what did you think I meant by "Not invalidating the rest of what you said"?
Indeed, and while I don't think anyone died as a result of this flaw, it was only a matter of time if not repaired and recalled.

The complaints/incidents are pretty terrifying: freeway speeds, stall, and complete power loss (e.g. power steering, hazard warning lights, brake assist, etc all gone) and you couldn't even restart until you put the vehicle into park/0 MpH.

The "lucky" people only had it stall out at traffic lights, the unlikely people had to go in the fast lane on the freeway.
No, you did not fall out of your chair. This site isn’t a platform to practice getting away with lying. Never post anything like this again.
A potent argument for legalization of opiates, IMO.

Something as simple as concentration percentages on packaging, as we have with booze, and smart usage pamphlets could save a lot of lives.
Nice I'd really like to have something equivalent in gdb, I'm really bored of stepping in shared pointer's code
The afflicted devices definitely make much worse usage of their airtime, but do they actually end up getting much more total airtime/TXOPs? The stations in question are definitely their own worst victim, and the impact they have on competing stations could be far smaller.
Sounds like good money after bad to me. But then again, they've got more than enough good money to spare.

Very dubious about the long term health effects of e-cigarettes. Unfortunately, a startup can move much faster than proper regulation.

S-town is hands down the best podcast I've ever listened to, it's incredible and I can't recommend it enough.
More interesting is why the purchase orders at usually at >=$1.0, and then there are sale orders at =<$0.999. Why someone would automate something to lose money so consistently? I guess this is what the author was calling out, not the numbers per-se. The numbers just point that the buy/sell are the same entity, human or not is irrelevant for the number. But the behaviour is the odd part.
Yeah seems crazy but not crazy since traffic can always be rerouted and once the line is cut you immediately know its out. I think the bigger issue is that people actually experienced an interruption of service.
Yes. Had this on several iPhones I used (SE, 6S, X), on iOS 10 and iOS 11, probably earlier versions, too.

I absolutely cannot understand why this isn't fixed. This happens so often.
Definitely for high entropy APIs at least. Checking if audio or canvas exists is just two bits.

But e.g. being able to read canvas pixels is absolutely insane that it’s allowed.

So if just these sources of huge entropy were default swithed off, as the article says, fingerprinting would be a lot harder.
Hi @md_
Remeber 3 weeks ago I replied to you that you are a tech guru and I had like to be friends with you.

Most of the rules of chess are trivial and thus should be deducible from observing less than one complete game. Rare things like castling might take a couple of games.

Love and politics have rulesets that are many orders of magnitude more complex; so complex that we don't even know how to write them all down.
>One strategy is to instruct late buses to skip stops where passengers don’t need to get off

My bus route does this...they skip entire loops of the route when running late.mainly the one with the stop I need to use to get home with the next closest stop being on a main highway about 2 or 3 km away. The best part is watching it drive right past where it's supposed to go with a mostly empty bus while me and 10 other people who have already been waiting a half hour now have to wait at least another half hour.

I have questions, if anyone knows something about hardware. What would a "silicon compiler" let one do? What exactly gets easier/cheaper and what exactly could new chip designs yield?
I'm not the person you're replying to, but I too would happily "die in my 40-es if I would get 25-yr-old body until the end of the life in exchange." I'm 36.

Oh boy, I will not lie, I have not yet read the article, but the headline is just asking for controversy.
what am I misunderstanding from this?

"Still, this should be mundane. People say a wrong thing on the Internet. It happens.

The trouble is, young "progressives" at the moment are falling all over themselves to be part of an expulsion — to root out and help exile some secret predator hiding in plain sight.

So if you have a target whose life you want to ruin for funsies, all you need to do is dig through their history for some circumstantial evidence, concoct a vaguely related story that makes them sound horrible, and circulate it in a callout post.

The problem, then, is not that someone pulled a story about Styx out of their ass. The problem is that Kiwi Farms is a well-oiled machine for producing hundreds of such stories, and the one about Styx is now listed on a Tumblr somewhere under a heading like "animal abuse", calling me a "known literal animal abuser". Because someone can't read Wikipedia."

Sounds like someone found these stories, misinterpreted them (wilfully or not) to sound like abuse, then got tumblr all riled up to harass them. I suppose the initiator wasn't necessarily from that space, but it certainly seems like tumblr/progressives are taking part in the harassment.
So on the contrary, I am a generalist and love poking around all over the stack. But that's it. I am a crazy breadth person but dont like to go into the depth at each level as that has way too much overhead for me. So that limits my expertise (but not love to tinker) in any one area. In companies/places where we need to go beyond POC apps, standardization (within stack and tech) kicks in, and you are not going to be productive if you are not doubling down on one or two areas. Worse are political problems where as an "apps engineer" where you are implementing a bunch of interfaces but diving deeply requires you to transcend org boundaries (again I am not a fan of that, just reporting as I see it), limiting your productivity.

> Oh, sure, people are very willing to report their suspicion of a crime happening to someone else.

I can say the same thing when you see a stranger entering your property that such case alone can be a crime in the Japanese law. I have seen Japanese people reporting such crimes.

> But what do you think is, say, the date-rape report rate for Japan vs. any other country? Something that's already a source of personal shame is hard enough to report; knowing that no investigation will even be attempted in response means there's no reason to try to overcome that shame.

Even in such specific type of crimes that is very difficult to investigate, some people report to the police. It is up to the police department to accept the reports and further investigate.

> Look at what reports ever get any detectives assigned to them, and the statistics will tell a far different story.

Your claim was that nobody bothers to report, but I oppose to the claim because I have seen people reporting, and thus I still conclude your claim is false.
Absolutely not good for public health long-term. Their recruiter reached out to me last December and it was a hard no for me based on what I understood about the industry.

People use them for starting to smoke just as much as stopping and they are also heavily used for non-nicotine products as well. I don't hold any moral judgements on the brand, or customers, but I was not going to spend my effort helping that become a bigger company.
As carriers change to fiber for all or part of their network, this is increasingly not true.

It does bring back fond memories of trying to explain to WoW guildmates that we needed to hurry up and finish the fight, because my power just went out. (Still online thanks to telco central-office based DSL and a good UPS.)

Echo <-> Lambda <-> ?? <-> Home Network

For ?? I've tried just making the lambda directly connect to an open port, but this requires me to open the router to quite a large range since lambdas don't have static IPs.

I'd like a VPN in ?? I have that for my phone.

As I dig into VPC and such it seems like it almost requires an EC2 endpoint for me to VPN into from my network which will NAT the request?

I'd like to not have to pay for an EC2 instance.
A great blog post here (https://wp.josh.com/2017/10/23/adventures-in-autorouting/) about some different auto-routing software.
I've fixed a few things in Open Street Map. But, for example, the city line for Redwood City CA at its western edge is totally bogus. That needs to be fixed by automatic reference to some authoritative source, like the USGS database.
Apple realizing this was important makes me think it is even more important for all of us to have the same kind of data in the public domain.

If someone can pony up 100K (what it costs to retrofit a car like the one pictured in the article) I could fund someone to drive it for 6 months around Barranquilla, Santa Marta and Cartagena in Colombia and put out an open dataset. I promise return the heavily used hardware after the 6 months and work with archive.org to publish it for posterity, then someone else can do the same in another country. Even if it takes us 30 years, it's worth doing.
The thing that should be a huge red flag about tether is that there is ~$2.5 billion in notional value of tethers floating around. (I think the bulk these are held by exchanges, on behalf of their customers or themselves.)

There is no possible mechanism by which these tethers can actually be redeemed for US $. The Tether company does not offer this service, which is incredible.

For someone to exchange their tethers for dollars requires them to have an account at an exchange that uses tether, with US dollar services, who reliably will let customers withdraw said dollars.

As far as I know, there are no such entities who are willing or able to provide such a service.

This alone should cause the tether peg to break.

It seems like this lack of liquidity (is that the right term?) would enable a dollar peg to be maintained at a much lower cost, through wash trading or other trading on an exchange like Kraken.

It's incredible to me that people are willing to entrust significant amounts of hard cash to this house of cards.

I guess some people have money to burn.

e-cigs have been proclaimed as between 95 and 99% less harmful than smoking, by some health charities.

If these figures are well grounded in evidence then... probably yes.
Also check out Mapy.cz (for iOS, Android, web). I find it much better than Google Maps for the hiking / walking use cases. It sucks for the "looking for a nearby restaurant" use case though.

I honestly think this is a hidden gem that more people should know about.
No, drug use isn’t consistently picked up in the aftermath of disaster. It’s often near the beginning, and lubricates destructive behavior, even pot.

Pot absolutely catalyzes issues in people’s lives. Many would be far better off not using it at all.
> "There's no point in securing DNS because your ISP can see what IP addresses you connect to."

I don't see the flaw in that one. It does seem kind of extra to secure DNS. What's the argument in favor?

> "State actors like China can circumvent HTTPS, since they control trusted CAs! So why use HTTPS at all?"

This one I agree is wrong, but not for something-is-better-than-nothing reasons. I think it's wrong because when Chinese CA's abuse their position they get blacklisted: https://arstechnica.com/information-technology/2015/04/googl...
They have. The problem is that efficient silicon layout is NP-complete and automated tools can't do better than humans today. At best they can assist and detect certain classes of errors. I'm sure Intel has invested more than $100 million on tooling by now.
number 9: eat less and dont be fat. your internal heater is your worst enemy. if you eat little, your body starts to lower its internal temperature and this will help you cool down. fat acts as an insulator so it is helpful to not be fat. i've been on a diet since christmas and my only problem is staying warm right now. i want it to be over 30 otherwise i have to layer up.
As someone who quit a 17-year cigarette habit for vaping starting in the early-ish days (2011, and it's come so far since then), nicotine salts might be the answer to those who relapse from trying to quit via vaping because it "didn't feel right."

Quite frankly, the narrative to smokers who want to quit from vapers who have has been "it's different, but be patient"; if a closer analogue gets out there that closes the gap on attempts versus quits, I really think there's a no-lose situation.
I'd assume it depends a lot on what you're searching for, and also what mode of transportation you're using.

If you search for something like "McDonalds", you care about which McDonalds is easiest to get to, and you don't really care about anything else.

Even if I'm looking for something more vague like "restaurants", I still usually prefer to see everything laid out on the map, but that's because I usually walk places, so location matters a lot to me.
A question that is somewhat on topic: does anyone have any articles or books on the vertical integration of some car manufacturers in the past where they had raw iron ore come in one side and cars roll out the other? I would be interested in other industries as well.

The energy to get a human off the planet is relatively small. Let's call it an MWh. (It's 9.1 KWh/kg)

A billion people is a PWh. That's 0.5% of the earth's annual energy use. It's a blip on the radar, especially since it will subsequently reduce annual consumption in the 10% range.
>The Zumwalt, F-35, B-2, and more are not cheap.

You're right, they sure aren't. But as a result no other military force on earth besides NATO has the capability to launch air superiority fighters from amphibious assault ships,
and perform multi-ton circumglobal bombing sorties. That kind of capability doesn't come cheap, and shouldn't be dismissed.

Take away the B2 and we are fighting to-to-toe with Russian/Chinese long range bombers

Without the F-35 we are on equal footing with Chinese/Russian carrier based aircraft

Without Zumwalt class ships, we are going head on against Chinese missile destroyers and subs of equal capability.

The whole point is that you don't want an even remotely fair fight. "Keeping up" with others's spending, even within an order of magnitude, is a really bad idea if you can help it.
I see many chip vendors on the list of participating companies.

Won't this project reduce barriers to entry for their industry ? and if so, isn't it against their interests to participate?
I don't think you can't, but you have to be aware of the demands graduate school makes on students, including working long hours on course work first and then actual research. If you are older with more commitments, it's just harder to commit to. It can also be pretty isolating, especially given that most of your fellow graduate students will be a bit younger than you (as well as being quite immature, as many have never had an actual career and come straight from college). By the way, what I've explained isn't great, it's terrible, but it's the system that exists now.

Of course, this is just a warning, just be aware of what you're getting into.
The scientist who coined “stress” wished he had chosen a different word for it
Agreed, but... they've already "won". Winning doesn't mean driving Google Maps out of existence, it just means being good enough that Google can't squeeze concessions out of Apple by threatening to yank GMaps.

A few years ago Apple disclosed that Apple Maps has 75% marketshare on iOS. [1] Mission accomplished.

That’s nuts, they could buy one Google per year. In five years they could own all the big tech companies.
But giving away most of these features would mean Apple has to host Google's data, something Google wouldn't compromise either.

Sure Google could've promised that they wouldn't collect which tile a phone requested by specific user agent, but that would be silly.
I think you have a point about the Nuclear weapons research, production, and maintenance, however the parent post was saying that the "bomb" was cheap, its getting it to the location its needed was expensive. Airplane and smart bombs are logistics.
>Even if it were the case that each replication made the chromosomes smaller (personally I would guess that there is a non-zero probability of them not getting smaller and even a non-zero probability of them getting larger thanks to a mutation) that would still only imply a hard limit on the number of replications.

The fact that chromosomes get shorter during DNA replication is a scientific fact. Chromosomes have padding at the end called telomeres that provide a buffer from the 'useful' DNA. There is an enzyme that can lengthen telomeres, and its of great interest to scientists interested in extending human life.

There is almost no chance that mutations:

a) regularly occur in such a way that makes the chromosomal DNA longer, especially in a way that offsets the base pairs lost during every transcription.

and b) occur in the telomere area of the genetic code, after all the useful bits of DNA.

If mutations did occur at a rate that would counteract the shortening of the telomeres, the rest of your genome would be mutating so quickly you would almost certainly die rather quickly.

There are a whole host of other reasons why what you wrote is nonsense, and I don't have the time or the space to address them all. There is literally no fact to what you have written. It is clear you don't have even a rudimentary understand the biology of genetics. An understanding of math doesn't preclude the need for understanding the actual mechanism of how things work.

The DoD budget, as usually reported, generally doesn't include funding allocated for specific operations (e.g. the Afghan or Iraq conflicts).

> focus on proven tech

The average soldier has always wanted proven tech. But what they really need (and what the officers ask for) is training. More HUMVEEs and Arleigh Burke destroyers, fewer wheel 4.0s and Zumwalts.

We are at the top of a power curve with regard to total dollars spent, but we actually about 4th in terms of defense spending as a percent GDP, (I think we're around 5th). Soft power remains our major advantage. Not that bad when you consider our outsize role in world military affairs.

It would be simple enough to rely on resource hashes to not actually contact the sources of files and then to skip or approve seeking hashes you can't get from your preferred shared caches. Thus a unique file gets ignored by the most anonymity concious.

I think there is a chicken and egg here combined with IP incentives to not fix how web browsers work.

I hoped the great firewall would have accidentally fixed this by making it preferable to refer to hashes that can be found in peer caches irregardless of CDN status.
