I'll defer to your experience on the first portion. I only did a bit of CS tutoring while in college, and sequential logic was one of the big issues I saw in the intro classes. Recursion was, of course, usually the next big hump after that. I definitely understand the point about opaque syntax, and do agree that, in both math and CS, the tendency is to simply throw these things at students. Compare to the approach taken by R6RS [0]; it's very explicit about symbols and locations and values and what operations like assignment mean.

On the second point, however, I still have some dispute. In maths or natural sciences, are you really expecting prior exposure to the subject matter? Or are you expecting a foundation upon which to build further? [1] I think the latter is a more appropriate statement. However, in CS, I feel it's more the former. "You must have experience programming, so that we can teach you how to properly program." If someone already knows how to program, what are they doing in a CS program other than getting a piece of paper that certifies their knowledge? Indeed, this is the argument you see regarding drop-outs or "equivalent experience" in lieu of degrees.

This is why I argue that we should instead find those fundamental building blocks and teach those instead. Basically, extract programming from the domain of computers, and figure out how to teach that. Then learning programming is about how those concepts apply to the domain of computers, much like how aerospace engineering is about learning how physics applies to airframes. [2]

[1] It doesn't help that something like "math" is really more of an umbrella term for a large number of fields across different domains.

[2] This is, I'm sure, a huge simplification. Hopefully you can see the intent of my point and overlook the crude analogy.
Honest question: if I can't see the artifacts without zooming in, is there any reason why I should care? Of all the conversion results offered, the Photoshop export actually looks the best to my eyes, so I'm genuinely trying to understand why the jpeg.io result would be considered better quality in this particular case.
Amazon will go from using many competing companies to using their own shipping service… maybe you have a different way of looking at it, but that's less competition in my book.
Keto is not a body hack that bypasses evolution. Almost all humans are descended from populations with seasonal eating patterns. Carb rich diet in spring/summer/fall, keto diet in winter.

The paradox is that keto diets, in the short term, seem to have a lot of great health benefits, yet all the blue zone diets are carb rich. My gut feeling is that for most people, the optimal diet in terms of health would be primarily high carb diet (with an emphasis on fermented foods and legumes), with occasional periods of keto dieting.
> It's not just homes or furniture: consider PC cases before about 1998 when the iMac came out.

Beige PCs were more of an '80s thing. In the early '90s, most manufacturers shifted to gray.

Honestly, though, I miss the colorful iMacs of the late '90s. Now they're all this boring white. I like seeing computers that come in a variety of color options. It's actually influenced my purchasing decisions for phones: my current phone is an ice blue Nexus 5X, and my last one was a bright red Nexus 5.

Your statement is true in San Francisco, but Pacific time zone also encompasses Oakland, south bay, los Angeles, and san Diego, where relatively few people commute using Uber compared to going out using Uber.

From personal experience, having driven for Lyft and Uber I'm two cities (Sf, sd) surge in SF does get acutely high in the morning, more broadly in the evening (work departure times are spread out over a wide range of hours), and acute around 2am. In California, bar closures statewide are 2am at the latest, so that accounts for unified departure times in multiple markets.
Then we should probably prefer levels of organization that have a track record of pulling off these types of feats, instead of private sector wanking.
"Multiple pepper's ghost displays stacked up" doesn't really make sense. Pepper's ghost requires a lot of space, and it isn't really stackable.
Logical move, in my opinion: it is easier to scale delivery at Amazon scale by doing it by themselves in cities/areas with enough critical mass.

> What if I drive 5x better and safer than the "average driver"? Doesn't that mean that these cars would now put me in more danger than I would normally be in with my own manual car?

Because you are unlikely always that.

Are you tired? Do you have a cold? Are you hungry? Are you playing with the radio? Are you having a conversation with a passenger?

The huge advantage that self-driving cars will have is integrated systemic control from multiple sensor sources and multiple transducer outputs--and they will never get distracted.

Human drivers have mostly 1 input: vision.
Human drivers have mostly two outputs: hand and foot.

The lag in that system from input to output is >100ms even if you are perfect (I will grant you an exception if your name is Michael Schumacher).

Automated systems will have far more inputs. Multiple vision sources. Multiple radars. Temperature readings. RPM readings. etc.

Automated systems have far more outputs. Steering is the same. Brakes on individual tires is the big starter. With electric, individual suspension becomes feasible. Transmissions change form and become electrically controlled.

And the lag in the system is probably <10ms. That's huge. That's the difference in reacting in roughly 3 meters (2.7 meters) vs 1/3 of a meter at 100kph (9 feet vs 1 foot roughly for 60mph).

Finally, automated systems will take subtle preventative actions all the time. They will "see" the child on bicycle on the sidewalk (the idiot detector as Google called it) and "know" that they need to find him again when they attempt to turn right or slow down significantly. They will see the dude on a skateboard and know that they need to give him an extra couple feet if they can in order to deal with him falling. I know very few drivers that are that diligent.
I believe you can, though I haven't tried it. Typescript will actually give you completion support for plain strings inside that switch statement, which is normally what I go with.
Great question. To the top!
The comment didn't state that beige in of itself is a bad colour, but when it comes to selling the house, a neutral colours works best because presumably it gives prospective buyers the idea of starting with a blank slate and not inheriting someone else's design decisions.
Right, but it's the same reason I got a RealD television instead of a shutter frame one. You're not gonna give a roomful of people (especially if they're children) shutter glasses. Too expensive by half. RealD glasses are easy to come by and when the dog eats a pair (or a couple, in my case) it's an inconvenience.

Headsets are great when you're only entertaining yourself. Terrible when you have friends you're entertaining.
I don't think a roadway can become a Place in this sense, except by being a really narrow street -- although a train, especially the sort you describe, is certainly better than a highway. Foot traffic makes interpersonal interactions easier, but also makes it easier to reach and notice storefronts, and is easier on resource consumption than anything else, even commuter trains.

I had this problem as well. I used to live in an apartment complex with a key entry that UPS, USPS, and FedEx had access to, but not Amazon. I never knew when they were going to arrive and they kept saying that they tried but couldn't deliver the package (we didn't have a code, only key entry).

Since I couldn't guarantee what carrier would be used, I eventually had to use Amazon Locker only. I live in a house now and no longer have this problem.

You wrote about H.264 compression, but not on how you transport the compressed stream over the network. Can you elaborate a little bit about that?

E.g. do you multiplex into a mpeg transport stream? RTP? UDP?

You know... I keep thinking that with source control systems like Bitbucket enterprise, etc... why aren't more mid-large sized orgs requiring a security signoff for every pull-request with a pull request to master/release branches being the trigger point.

I do a lot of PR reviews, and while I may not catch everything, I will catch a few things here and there... someone with that mindset would be in a better position to handle that from the start...

Having a few security guys that do PR reviews for about half their workload would go a long way to improving things.

We're going through an audit for an internal application now... there's 1 major flaw (SSL2/3 is enabled), a minor (session cookie isn't https only) and a couple trivial (really non-issue) concerning output caching on api resources and allowing requests with changed referrers (this can be spoofed).

In any case, having auditing earlier on and as a potential blocker would make each minor change easier to deal with than potentially much larger changes... the app in question was developed for the first 8 months without even a Pull Request check in place... by then many issues regarding code quality are already too late to fix completely. :-(

Can anyone tell me where the American trend of decorative non-functional shutters came from? It annoys me to put fake shutters on windows because they look fake, which makes them look odd. Especially ones that are too small to actually cover the window. That is soon weird and I can't imagine how you can make that mistake! Why not just real shutters?

Now on topic, I bought a beige couch because it was cheap, wasn't thinking about design. I have now learned beige is the worst color for a couch because it shows the stains from when I inevitable spill something on it.

"Amazon’s goal, these people say, is to one day haul and deliver packages for itself as well as other retailers and consumers"

They could choose to offer parcel shipping services to any retailer as part of the Amazon Marketplace Web Services API, just as they currently offer the Multi-Channel Fulfillment API[1], which allows a retailer to fulfill orders from any sales channel using the Fulfillment by Amazon network.

Amazon is growing quickly, and entering more markets..

but there's no reason to be alarmed. Amazon really isn't as big as they look. Revenue last year: $107B

Compare that to other things: About 1/5th of Walmart. 2/3rds of CVS. 10% less than Costco. 1/3rd more than Target. 15% more than Home Depot. Sure they're #1 in ecommerce, but ecommerce is only 16% of retail sales in the US.

There are actually quite a few companies the size of Amazon. And many of those companies are actually more profitable than Amazon too.
I'm bad at optimism, but maybe the takeaway here is that we're finally at the point where it's not the hardware or systems that are the biggest problem. The automation is actually working well enough that it's not the tall tent pole.
Most QA guys only check that something meets the spec/story requirements, not that the code is sane or testable... many don't even go beyond UI testing. That said, I think GP was referring to having a QA embedded as part of a team.

If you are going to have a gigantic ship able to carry a hundred people there will be exponential costs. And 90% of the cost would be getting it into orbit. And then there will be maintenance costs.

I think it would be better to just launch many small and cheap ships, then just leave them in space or let them crash into mars after dropping cargo by parachute with some air cushions. They could be carried into low orbit by a jet airplane, then use "dumb" rockets like water under high pressure in cheap lightweight tanks. And heat it up to vapor temperature using then sun.
How Uber Manages 1M Writes/s Using Mesos and Cassandra Across Multiple Datacenters
This (and painting everything beige) has been the advice of real estate agents for many decades, so I'm not sure I buy into the author's assertion that the rise of cable TV created it.

When I was a carpenter's helper in high school (early 90's), every house that was being flipped had to have beige walls, tile and accessories, though the appliances were stainless, so not much has changed.

I don't see how Amazon can do it cheaper (cost-wise)/better than UPS or Fedex, who have been optimizing for 50 years.

If they can't do it better/cheaper then the reason to do it is because UPS or Fedex are rent-seeking, and doing it themselves would bring Amazon's cost close to the actual cost of delivering

Is this any different from the '80s and '90s? I'm no fan of beige-everything in houses but it sure doesn't seem like a phenomenon of the 2000s to me (which the article claims it is). US apartments and homes have defaulted to being oppressively beige for pretty much my entire life.
Heh, everyone's experience is different. Until recently Amazon used UPS for everything and I never had a problem. They deliver the packages to the business next door. Just like it says on the sign by the front door.
"Emerging evidence from animal models and clinical trials suggest keto may be therapeutically used in many other neurological disorders, including head ache, neurodegenerative diseases, sleep disorders, bipolar disorder, autism and brain cancer. With no apparent side effects.
"

I suffer from bi-polar disorder and have been swinging back and forth between a "traditional" (IE eat too much of everything) and a keto diet. My wife has made comments that she can tell when I am on keto by my mental stability but I've never read anything to back that up until now.

My only problem with keto is cheating. If I cheat once then I crave anything with carbs in it. I don't usually have those cravings after about the first week of ketosis.

Man, I'm gonna save so much money.
My experience with Yahoo (admittedly ending more than a decade ago, so I'm sure much has changed) was that cost probably was a huge deal. I ran engineering for the European billing platform. We processed many millions of dollars worth of transactions a year.

Yet when I had to ask for a new database server, I had to submit a written request to a committee in Sunnyvale, with graphs and other supporting documentation to demonstrate that the load of the server we already had was high enough to justify it. Then I had to join a hardware review meeting, that included maybe a dozen people. One of them being either Jerry Yang or David Filo (Yahoo founders; I've forgotten which one of them it was that did these).

The people in the meeting, even excluding whichever one of the founders, easily cost Yahoo more in salaries for the time they spent discussing my request for one lonely server than the fully loaded amortised cost of operating it for a couple of years.

It's not that I have an issue with reviews, and cost controls - on the contrary, but some degree of delegation and trusting staff with budgets would have been nice. I mean, I could have trivially cost Yahoo millions of dollars with a few keypresses if I wanted to or didn't pay attention - they trusted me with the ability to mess up their entire European payments platform with basically no oversight, yet I couldn't approve a single cent of hardware expenditure for the production platform, and neither could my manager, nor, I believe, could my managers manager, who was responsible for all of engineering across Europe.

I suspect a structure like that may have created a lot of resistance to recommendations from the Paranoids even when engineering (they seemed generally very well respected; one of my old developers is part of the Paranoids now - he'd wanted to for years) would like to accommodate them for the simple reason that getting approvals would be a massive hassle and slow things down.

It's costing you future money when you paint it a 'non-natural' color in the lost prospective buyers. This is fine if you're loaded with disposable income, but for the vast majority of the US it's not worth it.
I wonder if UPS and FedEx will ever want to run their business on top of Amazon's platform even though it's a direct competitor now, like Netflix does.
The description is rather vague. It claims 2 million voxels and no moving parts. That's resolution of maybe 200 x 200 x 50; the depth dimension seems smaller than the others. Is is some optical system which projects on 50 plates (maybe less), or something like that? It looks like they're somehow optically remapping a projector to multiple planes at lower resolution.

There have been depth displays before - vibrating mirror devices (a mirror mounted on a subwoofer driver) and such. Today we have enough GPU power to drive a volumetric display, at least at the modest resolution of this device.

But it's awfully low-res. Once you get tired of the 3D effect, it's going to be painful.

Potassium is easy to get [1]. If you don't want to supplement with a vitamin/power, you can just eat a potato. Although that would go against 'keto diet'. I'm doing a IF (intermittent fasting) diet and I'm not restricted, so I could eat them if I wanted. IF is similar to keto, both put the body into a ketosis state.

There is a paint recycling service around my town (Portland) that filters and mixes old paints of different colors. It is very affordable, less than 1/2 the price, but as you would guess most of the batches turned out to be a bland beige-like color. Its performs as well as new paint and many people I knew who flipped houses would use it. These houses ended up mostly beige, such as in this article. It was a practical decision for them, not based on trends on TV or anything just trying to save cost and make more profit!
> The consequences should be that the company loses its ability to run a business.

Or gains ability to run it properly.

I didn't state it should be the only mechanism. There could be others. Those class action lawsuits mentioned in the article prove there are some. But the primary mechanism is users' responsible choice.

> shifting the blame onto users for not making it work

Actually I think the blame is on us, techies. We should create a culture where security matters as much as performance, pleasant design or simple UI. Both among users we live with and companies we work in.

And one fundamental problem of security for the masses is not solved yet: how a user can see if a product they use is secure without being a security expert.
That's fair, but just because version 1 sucks doesn't mean you won't still end up teasing your friends who don't own version 3.

It could work, even if this prototype doesn't.
The locals will still exist (but many of them aren't good, as parent said. As both a shipper and a recipient, I've had bad experiences with OnTrac for example), but this will create another national/international carrier, which I think is a plus for competition.

I would shop from Amazon again if I could choose to have something delivered by Royal Mail as then I know it would get to my door.

Amazon did the whole "left with neighbour" thing... but my neighbours are drug dealers and their clients come and go all the time... the packages never turned up and I'm hardly going to go confront the neighbours about it.

I shopped there for convenience, to reduce hassle, and their delivery service increased hassle.
