> So is it possible that in the distant past, a civilization would consider dark red and dark blue the same color? That instead of one "blue" category they would mix several other unnamed colors?

> I can believe it.

Different cultures divide the color space differently, but they don't lay it out differently. For a civilization to consider dark red and dark blue to be the same color, those colors would need to show similar activation profiles, both for blue-yellow cones and for red-green cones.

Zen was originally led by the same person as Opteron/K8/Hammer, Jim Keller... who now works for Intel.

I think the situation is a bit different this time around though as AMD’s bet on TSMC is paying off in a major way while Intel continue to flounder in the fab space.

> What use is "full use" if your system live locks!?

By "full use" it doesn't mean "get to the point of live-locking". It means if the heuristic is sufficiently conservative so as to prevent live-locking, it will also necessarily prevent usage patterns that wouldn't live-lock.
I actually rode on a boat with one of their motors, and it was a very positive experience, having grown up with gas-powered boats. It felt much less invasive and more like I was enjoying nature and the water, rather than just enjoying the boat. Like being on a sailboat. And you look down and don’t see the rainbow swirls of gas/oil in the water. I don’t know how much oil they actually leak, probably very low/none.

If nothing else, the noise is a nuisance on small lakes. I grew up next to a small community-governed lake on which all gas was banned. People have been using electric on that lake for ages, which is particularly feasible since it's a small lake (300 acres or so iirc). Electric for small stuff makes a ton of sense and has for a long time.

In the case of oil reserves, they are defined as the amount of oil which would be profitable to extract at current market prices. So it's not actually necessary to look in a new place; when the reserves start getting low, the oil price increases, and ipso facto the reserves are now bigger.

This is not true. AMC decided on its own to base reimbursements to studios on an average ticket price of 8.99. There was no negotiation, and no guarantee studios will continue to accept this rate. So far, studios are taking a watch-and-see attitude, hoping the overall quantity increases but currently, a studio exec sums it up by saying "I'm taking a haircut".

For this task I absolutely love my Xiaomi Mijia indoor air quality sensor[1].

Under $50, nice touch screen, WiFi, TVOC, PM2.5, CO2, temp, humidity. Have one by a laser cutter (particulate), one in a paint booth(TVOC), and one in the office conference room (when the CO2 is higher than 1200 its time for a fresh air). A+ product and so much better than what I could build myself at that price point. If you find yourself in mainland China do yourself a favor and drop into a Xiaomi store.

Yes, bond ratings were a big cause of 2008. Adverse selection/the market for lemons was a big part of that. Suppose the bond rating agency has a set of criteria to rate a bond AAA. You figure out how to structure your product to meet the letter of those criteria in one tranche, but the characteristics of the product's statistical distribution is very different than what the person who made the criteria was expecting. Or, you convince the bond rater into making some more statistical assumptions about the product that the product doesn't actually meet, and then you pass the AAA test with those assumptions in place. There is a blurry line between #2 and #3 which is basically just paying off the bond rater.

Ultimately modern structured products creation and sales is basically just like old-school used car sales. Put sawdust in the motor, roll back the odometer, and tell the customer that it was driven by a little old lady that only took it to church and to the supermarket. Caveat emptor.

I spent a lot of years keeping my money in the bank as I was always hearing news about "the next big crash is coming".

I agree, not necessarily with c++ but it's much better to build UI's with code than declarative xml crap.

I've been working in Security Per Se for more than 10 years and I would also be reluctant to call myself a "security expert" -- as would most of the people I respect in the business. (Free pass for CVs in motion of course.)

This is because many of us have very specific domain knowledge which probably doesn't map to a layperson's expectation of "security expert" -- and while I don't see much "Impostor Syndrome" I would assert that most branches of Security will humble you if you really know your shit, so a great indicator of someone who doesn't is their readiness to claim broad expertise.

Yes, most of the work in "security" is just "software engineering" -- but my own experience has been that for people who care about the security angle, plenty of domain knowledge accrues over time. You might not even realize how much you have, but others do: for me there is a huge difference between working with an ops person who has internalized the adversarial worldview of Security and one who is "just a sysadmin."

To be fair, throughout most of history, as long as China was under unified rule, it was almost consistently had the largest GDP in the world for any political entity, usually amounting to 25% share of the global GDP.

Compared to their historical performance, China hasn't even reached its peak.

I'd say political turmoil and conquests didn't harm the Chinese economy that much, but political stagnation during the crucial 19th century did. It was first disinterest of the ruling class in international trade (admittedly this started much earlier), which effectively handed over a lucrative business to European powers, who could in turn outgrow China.

The same political stagnation, as long as losing their position of advantage, has made China completely miss out on industrialization which was a great multiplier for GDP growth. This explains how a smaller neighbor like Japan (which embraced industrialization and Western-style colonization) could quickly surpass China and threaten it.

Not sure about the details of this picture, but hypersonic wind tunnels look very different than subsonic wind tunnels. The cross section of a hypersonic tunnel is usually small and there are not many moving parts. The high Mach number is achieved by discharging compressed air into the tunnel.

Before we did this outboard, I watched the Jamie Hyneman video you referenced. Because he doesn't use active thermal management of the cells, I would expect the cycle life to be ~ 300 rather than the 1500 we expect with this one. Since battery depreciation totals about 4-5X as much as electricity usage over the life of the system, not doing thermal management multiplies the cost of an outing by about 5X. The Hyneman system would effectively pollute more than gas outboards, because of how quickly the batteries would be consumed.
I wish NVidia would focus on integrating their software (like this DMA support) into more widely adopted frameworks like Tensorflow, Pandas, or Pytorch. Like TensorRT or nvidia-docker, they always have to release their own library that either breaks in weird ways or has utterly awful support (TensorRT).

Note that the 16-Volta contraption is basically only for use with NVidia’s own software. The two Xeons it has only have 80 PCI-e lanes, and 16 Voltas will consume 256 lanes, which is why each Volta gets its own flash. (Careful to shuffle your data before putting it on disk!). For that money, you’re better off building your own rack with a balance for your real application.

One way to avoid the PCI-e bottleneck for vision is to use NVidia’s own JPEG decompressor. Then only the file bytes have to cross the link, and the image tensor (which is probably 10x the memory) never leaves GPU RAM.
Communism was a roadblock, but China's relative decline (which really just means stagnation) started back during the Qing dynasty in the 19th century.

> You can disable the oom killer if you think its heuristics are misfiring.

You can't completely disable the OOM killer. Some in-kernel allocations will trigger an OOM reap and kill regardless. Too many parts of Linux were written with the assumption of overcommit.

Heck, as this issue shows even when there's technically free memory the OOM killer can still kick in.

I had heard about these issues before but never saw that in practice--at least not often enough that I looked closely enough. I knew Google and Facebook and others have been relying on userspace OOM killers for years to improve reliability and consistency. But only after having recently joined a DevOps team at a large enterprise with large enterprise, big data customers did I begin to see the depth and breadth of the problem.

Before getting into the hell-hole of helpless despair that is DevOps I primarily did systems programming. And, for the record, I always made sure to handle allocation failure in those languages where I could (C, Lua, etc) because as a software engineer it was always clear to me that, much as with security, an over reliance on policy-based mechanisms invariably resulted in the worst possible QoS. (Of course, in Linux even disabling overcommit is no guarantee that page fault won't trigger an OOM kill, but there are other techniques to improve reliability under load.)

> Is that due to dirty pages?

Yes, people have tweaked and turned those knobs and reduced incidence rate by maybe 20-30%. Yet nobody is sleeping better at night.

Computing shouldn't be a black art. The irony is that overcommit and loose memory accounting more generally was originally intended to remove the necessity for professional system administrators to babysit a system to keep it humming along. But now we've come completely full circle. And it was entirely predictable.

And before anyone says that cloud computing means you increase reliability by scaling horizontally, well "cloud scale" systems is exactly what are being run. But unless you massively over provision, and especially when certain tasks, even when split up across multiple nodes, can take minutes or even hours, an OOM kill incident can reverberate and cascade. Again, ironic because the whole idea of loose memory accounting is supposedly to obviate the need to over provision.
The illuminated globe example is much better than the one in the OP imo. The one in the OP isn't much different from parking a van outside the target office.
What this tells me is that when you build a site that has images uploaded by a user, you do nothing to those images. You just take the upload and stick it in an img tag to display it.

This is the exact problem with developers building for the Web. You'd rather avoid a relatively small amount of additional complexity than build something that's better for users (loads faster, reduces bandwidth, renders quicker).

Even ignoring WebP, you really should be resampling the upload to the right size and running it through something like imagemin to optimize the file size. And there are APIs out there that will do it all for you - it's a post request at most if you don't want to set it up on a server.

The Bonini’s paradox makes perfect sense, but I don’t think it applies to this case because the law is not trying to model anything, it stands on its own. It’s the same difference as trying to model the law and predict what is and what isn’t lawful based on some circumstances vs declaring that the model IS the law and it determines what’s legal or not.

Let’s take the tax code as an example. I’d argue that it already is a form of a program (maybe that’s why they call it code), but instead of something that I can run on my computer and explore and play with inputs to achieve a more beneficial result for myself, I have to instead pay a tax professional to do it. I think having the tax code executable would actually make it more accessible to people that are governed by it, not the other way around.

Most of the electric outboards have bad reputations for reliability, as you said. And the warranties are even shorter than those of gas outboards. But this one is the first to be designed from the ground up for electric, and while the warranty hasn't been announced, it will be far longer than those of gas outboards. The reason the other electric outboards break down so much is that there are weak links, borrowed from other products (like gas outboards).
