After 25 Years, 'Lost' OS/2 2.0 Build 6.605 Finally Re-Discovered (os2museum.com) 93

"In a fascinating example of poor timing, disk images of OS/2 2.0 pre-release level 6.605 from July/September 1991 were missing for over 25 years, only to show up literally one day after after the 25th anniversary of the OS/2 2.0 release," writes the site OS/2 Museum. An anonymous reader writes: It's the last OS/2 2.0 pre-release which didn't use the Workplace Shell (WPS), but "instead utilized the same old Desktop Manager as OS/2 1.2/1.3, which makes it the closest surviving relative of the Microsoft OS/2 2.0 SDK." Featuring a 16-bit/32-bit hybrid kernel and a "DOS Window" icon (as well as a few games like Reversi and Klondike Solitaire), "the look and feel was not quite the same as OS/2 1.3 and in fact was a cross between OS/2 1.3 and Windows 3.1."
The elusive 6.605 pre-release fell between 6.149 and 6.167 -- and "It is not known what possessed IBM to assign it a completely out-of-sequence number."

Salary-Comparing Survey Identifies Top-Paid Developers, Discovers North America Pays Better (linux.com) 267

21,000 developers were surveyed for this year's annual survey by VisionMobile -- and for the first time, they were asked about their salaries. An anonymous reader quotes Linux.com: [S]killed cloud and backend developers, as well as those who work in emerging technologies including Internet of Things, machine learning and augmented/virtual reality can make more money than frontend web and mobile developers whose skills have become more commoditized... The top 10 percent of salary earners in AR who live in North America earn a median salary of $219,000, compared with $169,000 for the top earning 10 percent of backend developers, according to the report... New, unskilled developers interested in emerging tech will have a harder time finding work, and earn less than their counterparts in more commoditized areas, due both to their lack of experience and fewer companies hiring in the early market.

Along with skill level and software sector, developer salaries also vary widely by where they live in the world. A web developer in North America earns a median income of $73,600 USD per year, compared with the same developer in Western Europe whose median income is $35,400 USD. Web developers in South Asia earn $11,700 in South Asia while those in Eastern Europe earn $20,800 per year.

For developers who want to move up in the world, VisionMobile suggests "Invest in your skills. Do difficult work. Improve your English. Look for opportunities internationally. Go for it. You deserve it!"

Amazon's Drone-Delivery Dreams Are No Joke (backchannel.com) 147

Backchannel's Steven Levy reports that Amazon "has a site at an undisclosed semi-rural location where it attempts to simulate the possible obstacles that drones will face in real-world deliveries." Amazon's drones reach speeds of 60 miles per hour, and can perform a 20-mile round trip, which makes Amazon believe they could especially useful deliveries to the suburbs, some rural areas. "The facility features a faux backyard and other simulated locations where drones might have to drop off their cargo." An anonymous reader quotes their report: "For a while, we were missing clotheslines," says Paul Viola, an AI expert who is charge of Prime Air's autonomy efforts. Now, Amazon's vehicles have a "Don't Hit Clotheslines!" rule in their code. There's even a simulated dog (though not a robot) that Amazon uses to see how the vehicles will respond to canine threats... Amazon is also planning for urban deliveries, with the idea of landing drones on rooftops [and] eventually it might expand to multiple deliveries per expedition, or even take returns back to the warehouse...

All of this is done without human intervention. Drones know where to go and how to get there without a human sitting at a ground station actually flying the plane... [A]n Air Prime technician can order a drone to land, but ultimately the drones are autonomous. Amazon envisions that eventually it will have sort of an air traffic controller monitoring the flight patterns of multiple drones.

If something goes wrong, "the first rule of Amazon drones is to abort the flight, returning to base or even carefully finding a landing spot from which to send a rescue signal. 'If it doesn't seem safe, it will land as soon as safely possible,' says Gur Kimchi, who has headed the Prime Air team for four years. (He previously worked at Microsoft.)"

Comment Re:$100+ for a family (Score 1) 360

A $0.15 bag of popcorn isn't costing me $5, nor is a $0.08 cup of Coke running me another $4, because I'd never pay that. It always amazes me that everyone except the movie theater industry seems to understand supply and demand. You're never going to make more money by charging insane prices for popcorn and drinks because those insane prices will stop the majority of people from buying those things at all. If they charged reasonable prices for those items they'd move more volume on those items. You're not making more money by selling those items for that much if you're selling way less volume. Let's look at two cases, one with those prices you mentioned, and one where they sell the stuff for a buck. Say they only sell 100 pairs at the high price.

100*0.15=$15 popcorn cost
100*0.08=$8 Coke cost
$23 cost, $900 gross, so $877 profit.

It is pretty reasonable that if those items sold for a buck a piece instead that you would have many more people buying them. How many would need to buy at that price to equal the same amount of profit? (Yeah, we're ignoring the overhead of labour and all that stuff.)

1-0.15=0.85 profit per popcorn
1-0.08=0.92 profit per popcorn
0.85+0.92=$1.77 profit per item pair
877/1.77=495.5

So they'd have to sell 496 pairs of those items to make the same money. So roughly 5 times more people would have to buy a popcorn and Coke. But at $2 versus $9 for that combo how many more people are going to buy? I'd never buy at $9, personally. I wouldn't even think about it. It is too much money. But at $2 I'd buy every single time without a second thought. How much cheaper would it have to be than $9 to get me to bite? Well, I don't know, exactly. Would $4.50 be enough? Meh. $4? Or $3? Perhaps. But $9 is nuts. And that's why nobody is buying it. The fact that you've got a monopoly in your venue isn't enough to make those prices acceptable. It still has to be good value, or overall you won't have people biting.

As far as I'm concerned, movie theaters should be practically giving away popcorn and soft drinks. A buck a piece and they'd have practically everyone buying, I would wager. Obviously with other items, candy, and who knows what else (I've seen burgers and nachos, among other things now! wtf?) there are going to be differing costs and profit margins. You could probably get away with better margins on items other than popcorn and soft drinks. But if you charged a buck a piece on a reasonable amount of popcorn and drink (i.e. not a freakin' garbage pail) I'm sure you'd be making a lot more money than you are with the gouger prices. Those two items are cheap as hell, and everybody knows it, so when you charge out the ass for them you usually just get a thumbed nose instead. Why theaters aren't actually playing with those prices to find the supply/demand teetering point is beyond me. Seems like business 101, no? The whole "We aren't making enough money, jack up the prices!" idea makes absolutely no business sense. You'd have to be a fool to think it did make sense.

And it isn't our fault that they don't know how to deal with movie studios concerning the pricing they get for screening their movies. Studios should want to have their movies shown. But it seems whoever has been running them ever since they started whining about nobody going to movies anymore has no clue how to do their job. Making it harder and harder for theaters is just another bonehead example of what not to do in business. But obviously it will be harder for theater owners to organize and finally start getting better business deals with the studios.

I seriously believe theaters would make way more money if they started charging reasonable prices, based on reasonable profit margins, for popcorn and soft drinks alone. Don't change your prices for candy and all the other crap you guys are selling now. But make the popcorn and soft drinks super cheap, because your cost is super cheap, and make a big stink about dropping those prices with really obvious signage in the place. Guarantee you'll start moving crazy volume compared to what you're doing now. That stuff is cheap. Sell it cheap.

If it actually worked very well you wouldn't have noticed it pausing while it waited after a cache miss. Any cache can only help by so much. In the case of hybrid drives, I never understood why drive manufacturers used such a small amount of NAND, besides cost. Sure, it is expensive to use. But if you put more on there I'll pay more, because it will perform better more often.

Comment We don't need to know. (Score 1) 418

We don't need to know how stuff works in order for it to be simulated in a simulator not written by us. She seems to be saying that it can't be a simulation because we don't know how it works. Saying that makes no sense. It's like saying I can't possibly play a video game because I don't know how to program a video game. Or I can't have eaten lasagna because I don't know how to make lasagna. For crying out loud, she says you can't simulate quantum mechanics because our computers use 1s and 0s. Does she even understand computers or computer programming in the least? She's a physicist. Some of that should be elementary to her. But is it? She seems pretty clueless in that arena.

"If you try to build the universe from classical bits, you won’t get quantum effects, so forget about this – it doesn’t work." Yeah, because it would be impossible to write an algorithm that simulates quantum effects. *eyeroll* Never mind that this statement of hers also assumes any potential simulation would have to be running on computers like we're using right now. Because other kinds of computers couldn't possibly exist. Because otherwise we'd have them, too. Heh. How this is over her head is beyond me, and yet, somehow, it is.

Comment never understood removing features (Score 5, Insightful) 266

Removing features simply because they're not used by everyone every single day never made sense to me. Even if it is something only a very small percentage of users use, so what? It's not like you have to write that code again every time you compile. It just sits there minding its own business. Leave it alone and mind your own business. It doesn't affect any other work, so why remove it? To save a few bytes of memory? We all have nine zillion memories now. Who cares? Some people use it. And if more people knew about it they'd probably use it, too.

Most people power on their machine, use the web browser, and office apps. That doesn't mean it would be beneficial to stop making all other programs just because most people don't use them. Same thing.

Why American Farmers Are Hacking Their Tractors With Ukrainian Firmware (vice.com) 500

Tractor owners across the country are reportedly hacking their John Deere tractors using firmware that's cracked in Easter Europe and traded on invite-only, paid online forums. The reason is because John Deere and other manufacturers have "made it impossible to perform 'unauthorized' repair on farm equipment," which has obviously upset many farmers who see it "as an attack on their sovereignty and quite possibly an existential threat to their livelihood if their tractor breaks at an inopportune time," reports Jason Koebler via Motherboard. As is the case with most modern-day engineering vehicles, the mechanical problems experienced with the newer farming tractors are often remedied via software. From the report: The nightmare scenario, and a fear I heard expressed over and over again in talking with farmers, is that John Deere could remotely shut down a tractor and there wouldn't be anything a farmer could do about it. A license agreement John Deere required farmers to sign in October forbids nearly all repair and modification to farming equipment, and prevents farmers from suing for "crop loss, lost profits, loss of goodwill, loss of use of equipment [...] arising from the performance or non-performance of any aspect of the software." The agreement applies to anyone who turns the key or otherwise uses a John Deere tractor with embedded software. It means that only John Deere dealerships and "authorized" repair shops can work on newer tractors. "If a farmer bought the tractor, he should be able to do whatever he wants with it," Kevin Kenney, a farmer and right-to-repair advocate in Nebraska, told me. "You want to replace a transmission and you take it to an independent mechanic -- he can put in the new transmission but the tractor can't drive out of the shop. Deere charges $230, plus $130 an hour for a technician to drive out and plug a connector into their USB port to authorize the part." "What you've got is technicians running around here with cracked Ukrainian John Deere software that they bought off the black market," he added.
