> To your last point, what if T-Mobile showed that by following its preferred QoS scheme it actually transferred more information over its last mile link?

That is very obviously not even close to being the right metric. All you need to do is find the one customer with their laptop tethered and running Backblaze or bittorrent, and give him all the bandwidth. Don't bother slicing up the airtime to serve other customers, because that'll just reduce the total data rate.

> Should T-Mobile sacrifice $1M in profit each month simply so that any customers who happen to be using an obscure protocol can get slightly better service?

Yes, unless they're prepared to stop advertising it as an Internet connection. If they're all allowed to be an "Internet service provider" that is really just a HTTP(s) service provider, then we're shutting out any invention that isn't well-suited to what T-Mobile can double-charge for—any P2P application, incompatible but superior successors like QUIC, and more specialized protocols like SCTP. Technologies that are obscure today could be lucrative and more resource-efficient next year, if allowed to blossom.

that you can generate an object that looks halfway sane and still gets you the sha1 you want.

The key phrase being "looks halfway sane". Git doesn't just look at the hash. It looks at the object structure too (headers) and that makes it highly resistant to weaknesses in the crypto alone. His point essentially is you should design to expect crypto/hash vulnerabilities, and that's a smart stance, as they are discovered every few years.
Great idea, thanks! Probably it has a bug as it doesn't detect the cf-... headers for me yet.

Lovely bit of debugging in this article, I really enjoyed it! Somehow a task that would be grueling to do myself is so much more enjoyable when read about.
I can't wait for VR resolution to increase so things like this work really well.

From my experience using the Oculus dev kit 2 there was too much of a "screen door" effect and it was hard to read text on a virtual monitor vs reading text on a real life monitor. It wasn't practical to use a virtual monitor to say, write code or surf the web.

But resolution will only get better! At that point will things get fun and I can see people eschewing monitors for VR "monitors".
The focus on legality and absolute enforcement of the law I think is cover, dog-whistle language, for anti-immigrant discrimination. (I'm speaking generally; I don't pretend to read the mind of everyone who says it, including the parent - I expect many are repeating talking points they've heard.)

For example, most laws are enforced unevenly and incompletely. Insider trading, for example, is widely practiced and rarely punished (EDIT: AFAIK, but I've seen plenty of serious evidence of it). Speeding, labor laws (making people work off-the-books, ignoring overtime, etc.), sexual assault rarely results in conviction, burglary, illegal activities by government itself (politicians, law enforcement, etc.).

To be incensed that immigration laws are not enforced completely seems disingenuous. That doesn't mean there are no issues to address regarding immigration, but I don't believe the issue is the rule of law. (In fact, to be incensed about anything is a good sign that there's not a lot of reason behind it - anger is cover for lack of reason and is a propaganda tool.)

It's particularly sad that people want to enforce the law on the weak and poor, the 'war on drugs' is another example, and not the people who can defend themselves and who are doing far more damage.
If I was reading about rerouting/cloning installments and secret rooms in nodes and datacenters across the US on news sites and blogposts all the way back in 2007, then there is not a shred of doubt in my mind that dozens, potentially hundreds, of mid-level and top-level government employees were aware as well. Which means the top brass were completely informed.
Bounty researchers aren't the only quasi-rational economic actors in this sytem. Cloudflare, we might surmise, get enough benefit from their bounty program that they're willing to pay for its administration costs and the occasional T-shirt, but they don't see value in spending more than that.

More than that, access to the service is actually the limiting factor for good bug bounty results. Cloudflare's bug bounty, we might surmise, works as well as it does because anyone can sign up for a Cloudflare account for free. For an enterprise CDN, who won't talk to a potential customer without the prospect of an $x0,000+/year contract, everyone who has enough access to the service to, in the general course of business, find and submit meaningful reports is employed by a customer, and likely prohibited from accepting substantial rewards. Everyone else either doesn't have enough access to submit meaningful reports, or the bug is so bad (like this one) that they'll report it regardless.

Arguably this shows that Cloudflare and other CDNs are right in their calculations: Tavis disclosed this bug to Cloudflare without promise of a payout, or even a T-shirt. Might some good Samaritan on the Internet have noticed the bug and reported it earlier if the bounty was more substantial? Perhaps. But in responding to a vulnerability of this magnitude, you want to work with someone of Tavis's caliber, who has the good of all the stakeholders in mind, not a profit-motivated rando.

> So in short I see no problem here to solve and I do not think government should get involved.

That's patently absurd. You can't just add a natural monopoly to a public good and come up with a competitive market. The most basic of economic analysis -- really, first semester stuff -- would tell you that these are the precise situations where external regulation is needed to even approach something that looks like an efficient distribution of resources.

I would describe your economic philosophy as something closer to a religion, but even most religions aren't provably incorrect.

This description is very misleading.

120,000 writes per second is accurate, talking about actual durable storage (disk) writes. But it's only 3,330 transactions, which should be the number that a user cares about.

I don't have proper data and I'm a bit rusty, but I feel like Cassandra could blow that away if you set similar consistency requirements on the client side (QUORUM on read, same for write?). Am I understanding this correctly, or does Fauna/Calvin give you something functionally better than what C* can do?
Yes, this is the argument that VoltDB made as well:

https://www.voltdb.com/blog/foundationdbs-lesson-fast-key-va...

My feelings on this topic are mixed. On the one hand, I think many of the specific examples chosen in that post are false (and have told John as much in person). On the other hand, the general point that you can squeeze out constant factor performance improvements by violating abstraction boundaries is obviously usually true.

Nevertheless, I still think this is a bad argument. While it's true that abstractions are rarely costless, they can often be made so cheap that the low-hanging performance fruit is elsewhere. And in particular, cheap enough that they're worth it when you consider all the other benefits that they bring.

When I built a query language and optimizer on top of FoundationDB, my inability to push type information down into the storage engine was about the last thing on my mind. Perhaps someday when I'd made everything else perfect it would've become a big pain (and perhaps someday we would've provided more mechanisms for piercing the various abstractions and providing workload hints), but in the meantime partitioning off all state in the system into a dedicated component that handled it extremely well made the combined distributed systems problem massively more tractable. The increased developer velocity and reduced bugginess in turn meant that I (as a user of the key-value store) could spend scarce engineering resources on other sorts of performance improvements that more than compensated for the theoretical overhead imposed by the abstraction.

I won't claim that a transactional ordered key-value store is the perfect database abstraction for every situation, but it's one that I've found myself missing a great deal since leaving Apple.

But I'm glad to hear that things are going well for you guys. Best of luck, this is a brutal business!

> CDNs are not prioritized on any ISP network. CDNs work because they have a shorter route to the end user, not because they have a higher priority.

So, anyone who can successfully define what they're doing as "not prioritizing" can entirely sidestep any regulation you have in mind.

Putting a server in the ISP's datacenter is a common approach. Traffic to those servers doesn't have to go over any external peering links.

> ISPs should not and do not apply QoS in their core

Many do. As one simple example, look at the ISPs that accelerate the first N bytes of connections, to prioritize interactive requests over bulk transfers/downloads. Other ISPs apply more sophisticated approaches.

> It's pretty obvious how you draw that bright line. Don't prioritize and don't congest interfaces.

> forbid prioritizing and saturation of network interconnects

So, receive and deliver all traffic, regardless of available capacity or financial constraints? Provision every part of the network so it can handle all the traffic passing over any other part, because they're not allowed to limit bandwidth in any way at any point?

A saturated interconnect might mean "we're trying to screw Netflix", or it might mean "we can't afford it right now" (either because they're a small ISP and don't have the money, or because they're spending it on something their customers want more).

Nothing wrong about owning them and preserving them but I feel bad about destroying them, if not for scientific purposes.

There are many of them but they are non-renewable. There is a finite supply of them.

And if we create market demand for them they might go very quickly. This is how we pushed rhinos into extinction. Rhinos seemed at some point to be very abundant, now they're gone for good.
A strange thing I've noticed about telecoms in the US is that prices never fall - instead consumers just get more value and are constantly upsold higher-value offerings - this is not a bad thing in itself, but whereas in the UK and most of Europe I can get a a few gigs of 4G/LTE data for my phone for about €10 - something you'd have to pay $50+ for in the USA. The same goes for home internet - the cheapest non-promotional rate in my area is $45/mo for 10mbps, but pay $20/more and you get 100mbps. Why isn't there a sub-$30/mo offering? I believe these prices remain comparable to what they cost (sans-handset subsidy cost) over the past 20+ years.

I have never had a shipment from two different sellers combined. In fact, I've had a single order from one seller split in to multiple orders because e-packet is so much cheaper per ounce than larger packages of similar size.

Occasionally I'll place an order that has a guaranteed delivery date in a timeframe I'm okay with, and the seller will extend the purchase protection outside of that timeframe. The other issues I've faced are that sellers will either substitute items for dissimilar items or not ship items at all if they are out of stock. I've never had a seller contest a package not received or package not as described though. I think they just figure they'll make a few dollars here or there on people who have forgotten to contest the order.

Tax money flows from organisations to people. The crucial idea: People are behind organisations.

This way owners of companies getting rich have to pay taxes for their robots. If they try to evade, government just has to wait for them getting the proceeds sooner or later.

A loophole is money leaving the country. Tax it as if it has been paid to a person.

Not for nothing, but most people of that mindset don't believe that the government is inherently bad, but that government powers should be closely and judiciously kept to a minimum to prevent it being used for bad.

There's a difference there, but like most arguments on the internet, the nuance tends to get lost in the retelling.

Regarding net neutrality, if memory serves correctly, it was but a few short weeks after the passage of NN that somebody was wanting to leverage the FCC's new powers to censor ISIS off of the internet. Wheeler, being a good guy, connoted that they didn't have that authority, and that even if it could be construed that they did, he was disinclined to exert it and give credence to the argument that they did have that power.

All of that was done basically in "the right way", but given the wild swings in administration changes, who's to say that some other head of the FCC wouldn't have been inclined to leverage the power that they might now have for exactly that reason? Are we sure that the courts would agree that NN doesn't give the FCC the right to censor individual websites? Are we sure that the courts of tomorrow won't?

Yes, I know that this is a slippery slope argument, and I understand the inherent pitfalls therein, but that doesn't change the fact that power can be used maliciously, and for some of us, the question of whether or not the problem is worth potentially sacrificing much larger swaths of the first amendment falls differently than for others. I personally don't fault any individual for whichever way they've decided, as there are possible curtilages of free speech on either side of the coin, but I'd like us to agree that being suspicious of vesting power unto an agency otherwise wholly unaccountable to the public is perhaps not the dumbest thing that Americans do.
Nope. Bigger :).
Because many customers don't actually want a dumb pipe.

Dumb pipes don't come with email addresses.

Dumb pipes serve YouTube more slowly, and might not have the capacity for HD/4K video. (Look at what server the video comes from; if you're on a major ISP, the server name likely has your ISP's name in it.)

Dumb pipes serve Netflix more slowly.

Dumb pipes can't hold as many customers.

Dumb pipes might not get as many customers.

Dumb pipes cost more.

Personally, I'd like a dumb pipe only as far as the nearest major datacenter, and then quite a lot of smarts in that datacenter. I don't just want a raw connection to a major bandwidth provider, though.

See also the last paragraph of my previous reply: I'd be in favor of separating out the "dumb pipe" as a utility, and then having ISPs operate independently from that. I think that would solve the majority of the problems.

Middleman sellers might not technically be a scam, but it's not often beneficial to all parties. I've spent some time working for a bookstore that has decent quantity of sales on Amazon, so that's where my perspective comes from. Some issues with middlemen:

- First, a lot of middlemen ALWAYS email the seller after placing an order, expecting the seller to omit any mention of the seller and how much the product cost on Amazon. Further, they request that the seller send a separate email with the tracking info for their orders. While this is probably find for random small sellers on Amazon, for larger ones like the one I was at, honoring all the middlemen's requests would cause HUGE shipping delays for all products, middleman or regular, just to deal with all the emails and special requests.

- Often they'll email again ("angrily", though it's just a canned response) if an item hasn't arrived 3 or so days after they placed the order. Even if the order was on a Friday night. And even if it's going from one side of the country to the other via the cheapest/slowest shipping method offered. So that's more needless emails to waste the seller's time.

- If there's an issue with the order, the middlemen often do not pass on details of the issue to the seller. Instead they just say (effectively) "There was an issue. I demand a full refund." Often issues can be resolved with exchanges or returns, but so many middlemen just demand full refund with no returns.

- Due to poor listings wherever the middlemen are relisting the Amazon products, the middlemen's customers often aren't aware of all the details of what they order. We'd regularly get things sent back and the complaint was "it's a used book" when that's exactly what was listed on Amazon.

- Some middlemen sellers are A-z Claim happy... Threatening to file a claim in their very first email to the seller, when they ask for no invoice or reference to the seller. We dealt with a few who would ask that you'd print out their own packing slip to send with the order and that you'd write their name on the return address of the package instead of your own.

- Often, middlemen include "(NO INVOICE)" somewhere in the shipping address, as a further instruction to seller to omit pricing info. Removing that part from a more automated shipping process (like larger stores use) adds processing time and increases possibility of mistakes. Plus Amazon requires that orders be shipped to the address provided, so I'm still not even sure if it breaks Amazon's policies or not to remove that from the address.

- We would frequently get confused or angry emails or phone calls from customers who bought something from a middleman seller who in turn bought it from us, because they'd see that our return address wasn't the middleman's name, or we'd include a packing slip (middlemen don't always ask for it to be omitted, and we wouldn't always comply if they did anyway) with our info and they'd see the price it really cost. That means more customer service time spent on that, and an upset end customer.
Here's a question: what's the trade-off in terms of return on investment between hiring salaried security engineers to administer a bug bounty and hiring salaried security engineers to find bugs directly?

Parent's claim, as I read it, is that it's a better use of an enterprise CDN's money to hire security engineers to find bugs than to administer a bounty. Seems plausible to me. Where's that line?

Finish that thought. I'm not sure what experience you mean to relay with your sentence.
I use this strategy too. Writing helps to memorize better and restore the forgotten faster by reviewing bullet points. If I deal with concepts which are hard for me to memorize or understand, I do some strange random messing around that info: reading it loudly (even singing), drawing schemes or impressions from a concept, associate it with something like color, song, place, sound, smell, food, person, etc, or connect it in some other way to strong emotional experiences. It helps to remember both emotionally and intellectually. Impressions are way easier to recall.
I doubt it. My Lyft onboarding experience consisted of watching a couple of safety videos at an auto parts store instead of a 1:1 "mentor" session. Last I heard, mentors are gone in San Francisco.

Lyft requires newer cars, which could bar totally broke drivers.

I have perfect background check, of course.

Lyft is definitely hands-on when reacting to passenger complaints. They likely have sentiment analysis software for comments by passengers.

Lyft passengers are ruthless in ratings. It took me a while to recover from initial ratings while I was learning. At least your ratings are a rolling average of last 100 rides so you can fix the problem of bad ratings with new rides. Last week should help: got 17 5-Star ratings and no negatives.
And yet markdown has no standard way to add captions to images. The internal docutils DOM is almost trivially mappable to a large subset of Docbook which can be done with rst2xml and some XSLT.
