It runs on some Broadwell and Skylake hardware. Docs are coming for http://www.acer.com/ac/en/US/content/series/switchalpha12 .

actually I don't have had a Broadwell / Skylake which I can play with. I have a MacBook Pro 2013 Late (Haswell). But I wouldn't try out something on my production laptop anyway ;) I also have a two Xeon Sandy Bridges lying around, but I didn't tried em, but I guess even with some changes it would run on it. I just didn't had time, after it compiled it already was 2 o Clock at night.

It will likely boot on earlier Intel platforms, though some tinkering may be necessary. The focus has been on Qemu and on some modern UEFI based systems (and the latter booting with gigaboot20x6, also part of the Fuchsia repos). Debugging early boot / bringup issues is massively easier if the machine has a standard serial port.

The problem isn't marketing. It's culture. While there are many benefits to free and open source software it encourages a take-it-or-leave-it attitude where software is released that's user unfriendly, full of bugs, and has little to no documentation. If someone dare ask about a problem they are having, often the closest thing to help they receive is "Why didn't you just use [esoteric Linux command]? Are you an idiot…

Maybe the cultural problem is actually that people like you expect open source projects to be like companies except that you don't have to give them money? Most open source code is written by someone because they want it and then they release it so others can see the code. Of course there's a take-it-or-leave-it attitude... why would they care if you take it? They don't get anything if you take it, you taking it was…

"you taking it was never their goal"

I'd disagree. That's pretty much the point of making the software open source: so that others can take and use it within the confines of whatever licence the dev decides. The point is to get it out there and into the hands of other devs, not for them to simply look at or dive through but very often to manipulate, improve and use.

In that sense these projects do actually operate the way companies do, but without the depth of support and speed that we would expect if we were actually laying down our cold, hard cash to get the goods.

Fuchsia is not a combination of pink and purple. It is the color your brain comes up with when it sees contradictory color signals (such as very high and very low wavelengths without the appropriate middle stimulation). It's the only color not in the rainbow. As you can see from this additive color program ( http://trycolors.com/?try=1&ffb5d9=0&c31cff=0 ), pink and purple create a lavender color. Whereas fuscia is wh…

To be clear on its origin its from the fuchsia flower which was made into the fuchsine dye which has these properties. See for its relationship to the visual spectrum [1] noting that the visual spectrum is ~400-700nm. The plant absorbs only the middle of the visual spectrum not the ends. This is the kind of stuff neither RGB monitors nor CMYK prints can capture well.

Note this isnt the complete story either as your eye may percieve it very similarly to purple anyway due to the way we see light (through our rods and cones which clump the spectra again anyway and are subtlety different for everyone).

Some more background on the 'line of purples', of which fuchsia is a part: http://hyperphysics.phy-astr.gsu.edu/HBASE/vision/colper.htm...

From your reference: "The 'line of purples' across the bottom represents colors that cannot be produced by any single wavelength of light." The GP is suggesting that fuchsia is special, but surely what he/she said applies to all the purples?

If you're really into colors, I suggest to read the xkcd: https://blog.xkcd.com/2010/05/03/color-survey-results/

Have fun!

Maybe it's useful to point out here that: - Chrome is built on Chromium, which is open source, but Chrome itself is not. - Android is based on open source technologies, but is, again, not itself open source in many cases. - Many, if not most, programming language implementations are not open source. In fact, you're dating yourself with this claim, as those with more experience remember the dark days of paying for com…

> - Chrome is built on Chromium, which is open source, but Chrome itself is not. If you've actually tried using Chromium then you realize that this distinction doesn't make much sense. Chrome IS Chromium + Netflix + Flash + updater/Omaha + flashier logo. > - Android is based on open source technologies, but is, again, not itself open source in many cases. Android itself is open source (AOSP) and is very much a usable…

> As you said yourself, your claims are out-of-date. AFAIK, the only three remaining language implementations that matter today that are not open source would be Oracle Java (very close to OpenJDK), Apple's LLVM form (naturally very close to real LLVM), and Microsoft's C++ compiler (AFAIK generally considered to be crap).

Not a much of experience in the embedded market, high integrity market, medical devices, hardware design, Fintech, HPC or deployments that require certified compilers, right?

I think you are conflating purple with (spectral) violet here. All purples are created from the mixing of high and low wavelength and are not present in the rainbow.

Violet, which is present in the rainbow, is not available for addition in the links provided since it can't be represented on computers using blue as their lowest wavelength primary.

There's a problem somewhere in the system of open source and the people who use it, and everyone above me provided many examples of dysfunction. It's dysfunction of a system with a very unclear reward framework, primarily centered around curiosity, pride, and drive. Developers want to build something they consider good; often they want to build something that others will find good and use, and there's intrinsic value…

Admittedly my response is another extreme from the parent comment. I run an open-source project and certainly don't have a take-it-or-leave-it attitude toward it. Although I also run a company behind that project and do get paid for some small subset of the work I do on the project; it'd be a lot harder to maintain that attitude if I didn't. I don't think open-source is perfect, it could be better and in my opinion i…

Yeah, it works for what it is—it's not wholly dysfunctional, obviously, but I was responding to a discussion bringing up several imperfect parts from both a creator and user perspective. I think they're common challenges in open source, and the problems are real, and shouldn't be ignored but rather improved.

Every system has flaws. Some systems are better than others despite their flaws. Yet, I have never met a system that couldn't be improved in some way with careful understanding of its structure, states and flows, and leverage points.
