With a few Torx screwdrivers and a Pentalobe screwdriver I bought from Ebay for $2 from Hong Kong.

Easiest laptop I ever took apart. Very intuitive. I could put the whole thing back together if I wanted to, which is nearly impossible with non-Macs once taken apart. It took 3 hours to take it apart and list everything, and I was doing other tasks at the time. Since all the parts are specially designed for Apple, they design for easy assembly, and therefore easy disassembly. They're not trying to hodge-podge a commodity SSD into their system by putting it in a housing held by 4 more screws. 1 screw for SSD. 10 for case. 1 for wifi. 6 for logic board. 6 for LCD. 3 for fan.

Since Macs are popular, there are lots of guides on ifixit, down to the "Take out this cable by lifting up this part, then pulling it out in this direction", along with high-res photos. A popular system also means a liquid market for spare parts. Apple has high standards and is notoriously incompatible with non-approved parts, so repairers prefer buying a used Apple component instead of 3rd-party parts when available.

Since Apple keeps a tight control on its suppliers, often the only spare parts are available from donors. For non-Apple systems, you can often find a manufacturer still selling new replacement parts, but not so for Macs. Lots of people out there will buy broken systems and then buy a replacement LCD or trackpad or logic board to bring it back to 100% and profitably re-sell it.

Rough Ebay value of each part:
Logic board - US$200
SSD - US$80
LCD assembly - US$300 (even with a few dents/scratches, people break these things and replace. Even if you can buy the LCD panel itself, buying the whole assembly makes repair so much easier)
Palmrest/KB/touchpad assembly - US$50 (same story: easier to buy the whole assembly rather than replace just the trackpad)
Bottom case - US$20
Wifi card - US$15
Set of screws - US$9
1 flex cable - US$7
Total: US$681

Actual selling prices may end up being 10-20% less, but I like to start my prices high, then lower it every few weeks until sold. As I said, price would be higher if battery wasn't dead, I didn't break a part off the power board and if the power adapter wasn't fraying).

Don't forget gas for heating in Europe. One cubic meter of low caloric gas approximates 10KWh. My household (Netherlands) uses 4k KWh but also 3k m3 north sea gas. So about 34 KWh equivalent total. Suddenly a not so different ballpark. (And I have an eye opening moment. Never knew gas was so full of energy.)
You only have to check 1 case in Go (`if err != nil { ... }`). What language lets you check half a case?
Actually humans can do that. We orient ourselves using landmarks. If you look at theme park maps, ski resort maps, maps of tourist areas downtown produced by local organizations, subway maps....

All of them are wildly inaccurate in terms of proportions and distances. But notice - almost all are oriented to people not very familiar with that area. Certain big monuments may be left out (the highway that runs by water park, the big electric station across the street etc.

>How is it less effective?

It's simply overkill and insecure to not use an established distros patch and package management.

The most effective thing is to create packages, or if you want some larger modifications a "spin" in fedora language.

I can't see any reason why you'd be restricted by packages. You can deploy your own compilers, your own shells, your own init system if you want. You can deploy patched kernels as long as you follow packaging guidelines.

It's smarter to spend time on packaging guidelines and internal yum repos than to build everything from scratch.
After seeing a lot of peers being mislead by big O I think most of big O articles on the web, for the sake of clarity or simplicity omits to express one thing

if we admits functions
* square_big_o O(n²)
* linear_big_o O(n)

then the statement

time(squarre_big_o(x)) > time(linear_big_0(x))

is not necessary true for every value of x

because the actual complexity could be

* 1000+1000*N
* 2+N²

in which case most of the time you will chose the square one, because practically it will be faster.

without this in mind, you got peer who tell you that this thing is faster because the algorithm is O(n) versus O(n²), though we're talking about a function that will always have n < 10, but yesterday night they read an article about big O and now they have to throw a "let's think about the big O" remarks for every single problem we meet

"issues with handling helium, rather than a design issue with the rocket itself"

I don't know if I would be so quick to declare "rather", but it would mean that they can baby the helium tanks to avoid any design issues for now.

No, part-out, just like most laptops, there is a liquid spare parts market for people that fix units with a broken this or that. People like to drop/spill on their laptops, and metal isn't very forgiving :)

FB claims that they don't leak information about the user, other than for advertising purposes, but is this really the case?

Here's how information leaks: if I want to know which people have an affinity with (e.g.) cats, I could target these users on facebook, and then use an advertisement where I sell (e.g.) coffee. Now, as a seller, I know if people click on the coffee link, these people are likely to be cat lovers.

So FB cannot claim that the information stays within their premises.

Of course the same holds for Google and others.

Hence all targeted advertisements should be made illegal until this problem is fixed. Good luck! :)

> LED lights consume not much power. How does that compare with the power used by a wifi + motion detector system running 24/7?

It's barely a rounding error. Sleeping the microcontroller, average current draw is a couple mA. LED lights draw around 500 mA.

Regarding the HVAC, what I made is more focused on keeping the temperature balanced by taking a weighted average of temperatures across the house, with the weights adapting to where people are, similar to the Ecobee thermostats but DIY. It also has a web interface where you can view temperatures and power usage, which is far more useful than I thought it would be.
It makes perfect sense that they'd be novelties. Play is creative. It's really harmful to science that it's become so institutional and bureaucratic.

Why can’t you plug the Lightning headphones that come in the iPhone box into the new Mac? Why doesn’t the iPhone come with the right cable for the new MacBook Pro? Why doesn’t Apple make a screen that properly works with its own devices? Why did Apple highlight how great the Touch Bar is for Messaging, but didn’t even port most of the new iMessage features to macOS properly? Do I have to carry two pairs of headphones now? How do I charge my Lightning cable mouse? Why remove the HDMI port, a standard that’s still incredibly popular for plugging into TVs? Why remove the SD card, a popular slot for… creatives using cameras?

Yikes. I mean... yikes. I hope Apple has some good answers to most of those questions.

A decorative toy map like this doesn't have to be accurate. Yes, you can ignore things for convenience. If I make a map that ignores the Pacific so I can focus on landmasses, it doesn't make the actual Pacific disappear. So yes, you can absolutely ignore things you don't want.

> absurdity

There's nothing absurd about it; interfaces are a reference type. If you have a reference to a reference, then checking the "outer" reference for nil doesn't tell you anything about the nullity of the "inner" reference. The advice is just a special case of "don't needlessly use pointers-to-pointers".
Yes that's probably why the industrial revolution didn't happen. There's a good comment below that explains other societal reasons why the industrial revolution didn't happen, like the lack of contract law and investors.

I also read a great theory once (but I can't find it again through google!) that the industrial revolution really required the invention of the cannon first. Building an efficient steam engine in roman times would have been incredibly expensive and dangerous, because of their primitive metal technology. The cannon created a tech race between nations to develop more/better/cheaper/lighter cannons. Which resulted in better metal working tech. Once you can make big pieces of metal that can withstand and direct the pressure created from explosions, steam engines aren't too far away.

But Heron's invention was still useful, and would have been the fastest moving thing ever built up to that time. Perhaps it could have been adapted to military applications, like flinging tons of rocks really fast at high speed?

It's bad. One one hand it gives something more or less true in a "casual" manner but on the other it's also intermixed with complete BS. E.g. wtf specular does not depend on view direction? It's called specular for a reason.

While I have no problem with people simplifying things for introduction to laymen, I think introducing falsehoods like this will do more harm than good.

Sun Surveyor[1] is another similar app for mobile that I have been using for years now and have found to be fantastic for planning photography trips. Knowing the exact times and angles of sunrise, sunset, blue and golden hours, moon cycles and the path of the Milky Way center really is a game-changer for landscape and night sky photography.

If you're heading into built up or mountainous areas, the desktop version of Google Earth[2] is fantastic for trip planning too. You can turn on sunlight mode then set the date and time appropriately and interactively figure out and bookmark the best locations to be in, taking into account shadows cast by mountains and sometimes even buildings.

It was a fundamental break-through. We were no longer at the center of the conceptual Universe. Whether that something is the Sun, the center of the Milky Way, or doesn't actually exist in space, doesn't matter as much as the initial realization.

I can't agree more, when interviewing I always ask this kind of questions of "theoretical knowledge" not to have the actual answer, but to see how candidates reacts when they don't know. Because if the guy not only admits he does not know directly and is eager to know what it is briefly, then you know that giving your team and environment is favorable to learning, the guy will soon be able to catch up, and it's certainly the same guy that one day will bring in the team's "tips and tricks" channel an article or an insight that will make the team's knowledge grow too.

After initially being skeptical and disliking him for libertarian leaning political reasons, I've come around to wondering if John Maynard Keynes might have been even more right than we have imagined.

Slave labor is kind of an extreme case of the paradox of thrift. Slaves have no disposable capital and they flood the labor market down to zero. Slavery is like a permanent deflationary spiral. There is just no reason to innovate or invest in anything except conquest and luxuries, which describes most ancient cultures well.

Had the Greeks or Romans abolished slavery and set a minimum wage we might be flying to Proxima Centauri in a fusion rocket starship by now.

Also, source of electricity may be non-trivial. Battery would need creating acids and non-metal container to store them. A simple DC generator would need a permanent magnet.
I've given some thought to #2, from the perspective of a mildly-transhuman child left by herself in a jungle (it's a novel..), and came to the unfortunate conclusion that...

Maintenance is a killer. There comes a point, fairly early in technological development, where it's simply impossible for any single person to keep everything working and still have time to improve on the situation.

That's true for even the most benign of environments. Hana, unfortunately, was stuck in a rather damp jungle.

Think that is really accurate.
This isn't going to answer your question but the reasons why we support this Fedora VM image is because our projects make use of it in CI environments and also because one of our team members worked on the GNOME screen magnifier. I saw your question regarding whether Eclipse paired with Orca is a viable, accessible option on Fedora for Java development -- I don't use Eclipse but I can ask around and get back to you. I would suggest that if possible you could try Eclipse in the Fedora environment I mentioned with a project you're familiar with; I can help with at least installing and configuring it but ultimately customizing something like Eclipse is a personal and soul searching experience :P

BTW, we provide a Windows 10 Vagrant box [1] as well. I just didn't mention it because it doesn't come with NVDA or the evaluation version of JAWS yet. That will happen soon though.

He got to where he is now because the visionary put him there.

Like all reductionism, Horowitz thesis looks good in a business book, it makes the world simple.

Reality is complex and that statement ("a company works only well with the visionary at the top") it's kind of a self fulfilling prophecy (the company is doing good. His CEO must be a visionary, then, since he anticipated the needs of the market).
Vagrant works pretty poorly with VMware, even with the paid plugin. So I use Virtualbox for Dev even though I have VMware installed too.
>One of the strengths and success criteria of the Mercator projection is that it allows us to largely ignore the vastness of the Pacific Ocean on our maps. Notice how much of this map is taken up by it. While interesting from a planetary perspective, it simply isn't that important to everyday life of most map users.

Totally agreed!!! To say nothing about totally irrelevant places like Africa.

I've written up some of the other advantages of the Mercator projection that you've missed, here:

In short, it's the best and most useful design and nobody other than maaaaaybe some planetary geologist should possibly concern themselves with something as irrelevant as objective reality.

Another factor is that high voltage DC step-down is significantly harder than AC step-down, especially once you get into the 100's of KV. With AC that's relatively easy, transformers are passive components, very well understood and can be made for extremely large power levels without getting into exotic engineering.
I don't really believe there are good answers to those.
Java, Go, and C# all do stack allocation either implicitly via escape analysis (Java), explicitly via value types (C#), or both (Go). I don't know that this is "most" (perhaps by marketshare), but these are certainly 3 of the most popular languages in this space.

Runners, horses, ships moved communications fast enough. Even if you knew ceaser was coming to Rome, transport speed meant you couldnt do much with that.

I was going to mention AFL as well, but for a different reason (unless I misunderstood your post).

Disclaimer: I've never used AFL myself but I've read articles about it with great interest (especially the crazyweird experiment when it created valid JPG images out of thin air, that was brilliant).

So during fuzzing, it finds lots "interesting" program-inputs (that cause crashes, bugs and weird behaviour). But it also has a different mode, where it tries to minimize these program-inputs to the essential parts that cause the behaviour. Since the bugs found are generated from (semi) randomly mutated inputs, the "interesting" inputs often also contain extraneous data that just happens to be there, but isn't relevant to the particular "interesting" behaviour found.

From what I understand, it uses this minimization mode after fuzzing, between sets of fuzzing runs (for good seed inputs to start with) and perhaps also during fuzzing (not sure). I read about it, but I forgot how it works exactly. It's probably explained on lcamtuf's site or AFL docs. I'm assuming it uses a similar method as proposed by dflock above, iterating deleting random stuff as long as the "interesting" behaviour remains.

I also wouldn't be surprised if non-AFL style fuzzer toolsets have similar test-input minimization tools. They also generate random inputs usually, just not AFL's clever pruning technique of keeping track of previously-seen program states to guide the random search to prefer novel states. Which I believe is the most revolutionary idea that makes AFL perform so uniquely well.
