That was my reaction too.

I don't think there's enough of an improvement over the status quo experience of crossing a border into a new country and getting to your hotel. In "very foreign" places the value might sometimes be much greater. But, in those situations if you could afford to spend $300 on a service like Solve there's a good chance you're staying at a place that will offer similar functionality or you're meeting up with people who will send someone to help you.

That said, if I could book Solve pretty last minute then the prices might be more reasonable, or even be too low. If a flight is delayed and I'm going to be cutting it close for a meeting then $300, or even $600, to remove all uncertainty about the border crossing could easily be worth it. Or if I get to border control and see there's a huge line, I might be more likely to give in to the temptation and spend money to get out of waiting for an hour.

I'm also super curious about the vision for scaling this. Even if the prices came down it seems like it's targeting a relatively small market. Plus, it seems like there are inherent limits on the product's scalability - you could only have a relatively small percent of all fliers using Solve before it would get congested and offer a worse experience than not using it! So, you guys must have something bigger up your sleeves! I'm curious where you see it going. Maybe a wider range of personalized travel services (so, still a small number of users, but more dollars per transaction)?

I dunno, maybe you just need to convince a handful of big companies to offer this as a perk and you'll be all set. Maybe that market is actually a lot bigger than I'm imagining off the top of my head.

All of that said, I do really like the idea of magically making the process of getting from my airplane seat to my destination faster, more comfortable, and less uncertain. I would definitely be a customer at the right price point and/or value prop.

What is fascinating is to see FB successfully employ the same general strategy to publishers as they did advertisers.

With advertisers, they got everyone excited about the ability to reach their audience through a new channel. It had some similarities to email in that FB encouraged you to get Likes on your page, and then everything you posted would in theory reach your audience. Then they gradually tightened the screws in the name of declining user experience with too much garbage in the feed, which became algorithmic instead of sorted by recency.

This in turn let them flip the switch and move to basically zero reach unless you pay. And not just pay a flat rate based on however thousands of users you have (like email providers), but a dynamic pricing auction that maximizes revenue for FB. So advertisers invested all this time and major dollars on building their FB base, without actually owning the contact info or the ability to reach those people without paying FB. Frog successfully boiled.

Now with publishers they got them all excited about the reach they get for their content, and then slowly choke them via Instant Articles. Since publishers are so reliant on the revenue from FB, they have ZERO leverage in these negotiations, much like when Google says "sure, you don't have to have your content indexed." FB can now decide how benevolent it is feeling towards publishers, and there's nothing they can do about it.

HK was an important opening to the rest of the world when China was closed. China was able to source limited imports and do some exports through HK. So HK was just for ideological convenience (we shun westerners! But we still need some of their money and exports, so let's do biz through HK). Obviously, HK isn't required for that anymore. Likewise, HK used to be the place to get actual Chinese entertainment that the mainland wasn't capable of producing due to ideological constraints...that barrier has almost went away as well.

These day, HK's only remaining use has been as a proxy for the conflicts between different factions of the CCP. But even this is tenuous, as evidenced by the book store employees being disappeared a couple years ago (books being an important tool for pointing out or making up the crimes of the other faction).

33% faster encoding x264, at what price? Ryzen 7 1800X: $499, Core i7-7820X: $599 (+20% over Ryzen). You can also cherry-pick tests where the Ryzen gets better performance or better performance/price, and not just tests involving AVX usage. Also, in cheaper Ryzen's the performance/price gets abysmal in favor of AMD. BTW, you can compare also a $599 GPU performance encoding x264 versus that Intel CPU and see how "fast" are Intel CPUs in comparison.

I think your missing the time scale to which this is happening. what I understand is that it's an article that tries to have a good UX when the article has minimal traction let's say 15 visits per hour, but high share-ability and once the network effects takes over and you have 1500 visits per hour, you pump in the ads.

this is fundamentally different from the usual ad-supported website because the quantity of ads is consistent across all users.

it's a clever dark pattern IMO.

I've long suspected that Web 3.0 will mark a return to valuing more curated content, genuine expertise, and slower-paced and probably more fully moderated discussion.

The community-driven content of Web 2.0 has had a long run, and it surely isn't going anywhere. It's achieved some truly amazing things: who would have thought, even one generation ago, that today we'd have information sources like Wikipedia, or that they'd be as good as the best of them really are?

However, Web 2.0 has also shown us the weaknesses of a system where all voices are equal regardless of knowledge or experience. It has proved surprisingly difficult to create and sustain self-moderating communities that function as meritocracies, both in terms of the accuracy of information or validity of advice, and in terms of the challenging legal and ethical questions when one possibly anonymous person's free speech butts up against the real and possibly serious consequences of what is said for someone else. That same Wikipedia has had entire long and well-established pages on subjects where the content was utter drivel for months or years at a time, because it was utter drivel that enough inexperienced people believed, and there was no effective mechanism or incentive for a real expert to set the record straight.

It seems likely that many of these issues could be overcome if we combined the undoubted enthusiasm of the masses for having their say with a greater amount of input and influence for real experts and diligent moderators. However, that probably requires giving up a degree of the anonymity/pseudonymity we enjoy today, which does usefully allow for more honest and open discussions at times, so that credibility can be established with sufficient transparency to generate trust. It probably also requires people to actually pay real money to support the content or offset the running costs of discussion forums, so that a greater degree of expert contribution and/or moderation is actually viable without relying on ads, affiliate marketing schemes, or other secondary revenue sources that cloud the issue. That in turn may well require some form of either micropayments or syndication, and whoever cracks that one is probably the next Stripe.

There are a few good pages/books on this ("Bit Twiddling Hacks", and Henry Warren's Hacker's Delight).

On my wishlist: updated versions of these for modern architectures and SIMD. Full disclosure: am Intel employee. That said, modern chips of all strips (x86, ARM64) all can do some amazing things with low-cost SIMD and bit-manipulation instructions. It would be interesting to see what smart folks come up with using these. Obviously you can make the 'bit extract' function really boring with PEXT, but what cool tricks can you do when you start with AVX2 and BMI1/2 as a baseline?

Taiwan was universally opposed to "one country, two systems" even before China starting cracking down on Hong Kong though: hating it has always been the one thing the Blue and Green coalitions can seem to agree on. So in that sense China's position hasn't actually been made any worse.

> Slightly more specifically, if the stack is growing into space that the heap already owns, you don't get a page fault.

Exactly. But the stack is only growing in the program's view of the world.

> So the OS assumes that the stack already owns that memory

Nah, the OS is blissfully unaware that the program has moved its stack pointer to point off the stack. If anything, the OS wrongly assumes the program is still operating within the stack space explicitly and rightly reserved for it.

And the program in turn wrongly assumes this memory newly referenced via the stack pointer has been reserved for its stack, because it wasn't killed for accessing it.

> Now if you write to the heap, you can corrupt the stack.

That is right. You will corrupt what the program believes to be stack.

At the same time as China has been increasing it's grip on Hong Kong, it has also been liberalizing China (especially economic rights).

What are the chances that in 30 years (2047, the 50 year mark), China will have significant civil liberties and democracy? I have no idea, but I'd like to think it's at least kind of likely.
For those interested in related work, Mark Currie designed and patented one around 2008 that intercepts logins, injects correct credentials, and handles the TLS on a USB device. He described it to us on Schneier's blog as follows:

"The device is a small USB gadget that effectively acts as a SSL proxy, allowing it to have direct and first access to the clear text data to and from the host. It has a small user interface so it can accept (and optionally store) specific user input (PINs, passwords, credit card no, etc) and display specific user/server output data fields. This allows it to insert either pre-stored or on-demand passwords etc. into the outgoing stream. It also allows specific confirmation data fields from the server to be displayed e.g. a beneficiary account no., balance amount, etc.

So the actual passwords are only available in the comms path and PC-side in SSL-encrypted form and any confirmation fields (beneficiary account no., balance amount) are confirmed to the user via the integrated display just before being SSL-encrypted, so they cannot be manipulated before going to the server.

In terms of inserting a password, it automatically detects the standard HTML password form field and the corresponding response message (used by all secure web servers), and substitutes a dummy password for a real one. I have confirmed that this function works on all the major web sites e.g. PayPal, Amazon, E-Bay, Google, LinkedIn, etc. and at least four banks that I have checked (probably most).

For displaying server confirmations, it might require a little help from the host server in terms of detecting the HTML display field, or else it would need to store a profile for each website (not ideal). However, it costs the host service very little to tweak a bit of HTML.

I agree with you whole-heartedly about the user being in the loop. That is what my aim was with this device – The gadget directly authenticates the server through normal SSL and displays the server validity directly to the user via the integrated display. In Internet banking the main threat is the beneficiary account number. As long as the user is satisfied that the account number displayed on the device is correct then it cannot be manipulated other than by breaking the SSL crypto. In this it is almost identical to the IBM ZTIC. The difference is that it also allows the user’s password to be sent securely to the bank and therefore does not require the use of a client cert (so no private key needed)."

Exactly this, although it's more a useful mental model / philosophy than a concrete nullifiable bit of science IMO.

In the meditation style I prefer, it's useful to think of the subconscious/primitive brain as an elephant that is somewhat under control of the driver (the modern brain).
I worked on a handful of products using Edison, and was speaking to Intel less than a month ago about their Joule line at a conference, where they assured me Joule was the future.

All of these chipsets had (and still have) huge promise, but have been mired in really puzzling and terrible board design issues.

You can tell that there are two different groups at Intel, the "Core" and the "Iot".

The Edison was super powerful, price competitive, and an honestly wonderful platform to dev on. YOCTO, while a weird decision, was a pretty vanilla Linux flavor and easy to pick up.

With all that promise though, the botched the silicon. The 2nd cpu on Edison, the Quark 100mhz one, never actually worked. They were shutoff in firmware from day 1 because of presumed hardware issues.

Even worse (and the reason we stopped using Edison), the SPI bus had so much electrical crosstalk on it from not being properly routed or shielded, you couldn't use it at anything over 25hz with a SINGLE bus endpoint. This removed 90% of the real-world uses for the Edison to drive displays, sensor and motor arrayset al. Intel knew it was a problem and consciously decided not to Rev the board to fix it.

Gallileo and Joule are both underpowered and incredibly overpriced devices. Today, the raspberry pi 3 is the hobby standard, and in nearly every real world use case, it is orders of magnitude more performant at 10% or less of the cost.

Intel IS is trouble, because this is their third botched attempt to enter the world of embedded computing and mobile computing.

First was the Atom, which isn't bad, but is too power constrained to compete with ARM. They made some good efforts here, but the cost is higher and perf/watt significantly lower than ARM.

Second was their foray into mobile, trying to branch from Atom. Anyone here ever use an Intel powered phone? Well they spent billions on it, never to have a mass market device actually appear. Same problems - while have equivalent performance to ARM, prices were 30-50% higher and performance per watt was significantly worse.

Now here we are with attempt 3. With the same issues. Intel fundamentally doesnt know how to design, manufacture or sell embedded chips.

It's a completely different market motion, different customers, different constraints, shorter cycles and much much different competitive landscape.

AMD isn't going to "beat" Intel. They have fundamentally the same problems. Both AMD and Intel aren't going to go bankrupt, but they are going to continue the slide into much smaller scale manufacture.

They are both being eaten by the dozens of ARM vendors, by the FPGA movement, and by public cloud data centers. It's a reduction by a thousand cuts, making it that much more difficult to do anything about it.

I worked in a books warehouse before college and two of their books had a little accident and ended up in the rejects bin along with some of my course texts. I lent the P and R books to someone and forgot who so actually bought them later on. They are amazing.

I also remember how short things like Iterated Function System plotters could be - eg a few dozen lines of BASIC could get you a complicated fern piccy in a few seconds on a 80286.

I suspect they had access to some decent Unix workstations with expensive displays. The quality of the plates was breathtaking - you can barely see the graduations in many of the images and they are totally smooth in most of them.

That's like saying that electrical circuits are the reason that a web browser shows a web page when click on a link.

There's no "home button transistor", but there may be transistors that, by their switching, control the appearance and action of the home button.

Mechanism isn't rationale.

Web browsers work because they were designed at a high level to accomplish a task, and a lower level of primitives was assembled (literally and figuratively) to implement the task.

When we talk about reasons for something, we normally have intention in mind, and we're talking in a high level abstraction mode. Mechanism is just an implementation detail. In the absence of a designer, mechanism doesn't cease to be an implementation detail; we don't have legs because of the signalling actions of cells in the embryo, triggered by DNA and proteins, cause fleshy buds to grow into bony appendages. We have legs so we can move around, and we can move around because in our ecological niche we're more successful moving around. The reason for legs doesn't lie in biology at the organ or chemical or physical level, because those are implementation details to the reason mode of thought.
I've visited Amsterdam on several occasions, and I am always amazed at the low prices you guys pay for bike stuff, especially compared to the US/UK prices I am most familiar with. I found it similarly cheap in Copenhagen as well - I guess greater demand helps drive prices down.

The style of bikes that are popular in Amsterdam and other relatively flat European cities often aren't that commonly found in many other countries in my experience - the incredibly popular in Holland 'coaster' brake design (where you stop pedaling/pedal backwards to brake) is borderline dangerous on very steep hills, but works great in flat areas, making it pretty uniquely suited to cities like Amsterdam. Similarly, you guys rarely need to bother with gears, or need so few you can use much simpler to maintain hub gear systems rather than finicky external derailleurs. I've almost never seen a new bike sold in the UK with coaster brakes, largely due to safety on hills. Similarly, it's pretty rare to see a coaster brake equipped bike in the US. I sure wouldn't want to try stopping at the bottom of a long 30% grade in San Francisco on coasters...

Do they? It's my impression that Intel's integrated GPU cores are currently best-in-class in performance-per-watt, even compared to the PowerVR cores in Apple's mobile products.
I interpret it to be that the answer is whatever we make of it. Your interpretation tells me more about your mindset than about any actual truth. Taken that way, meaning is what we project on it. You project a number as futility; a numerology-leaning individual could project a different meaning.
