The new standard, MU-MIMO (Multiple User — Multiple Input and Multiple Output) has a clunky name — but could make a significant difference...

I thought clunky names were an engineering tradition, like CSMA/CD (Carrier Sense Multiple Access with Collision Detection), which means, Listening Among Others for a Chance to Speak.

I'm curious, or maybe just ignorant, why the open source community does not already have a mature, widespread file storage application that is peer to peer, like BitTorrent Sync. Maybe because peer to peer is so much harder than client-server. But I would have thought it would be further along by now, given our:

- technical savvy
- awareness of the importance of good back-ups
- distrust of corporations and governments

If we had a free file back-up service that was standard for Linux (or if there were two or three, for the sake of competition, but that at least each distro had one that it picked as its standard), then I think it would help Linux catch on as well as improve the sense of community: I'm helping host some of your data, you're hosting some of mine --- even though I have no idea what or whose it is because I have just a bunch of encrypted shards.

I hate to say this, as much as I sympathize more with Netflix than a major studio, but shouldn't the studios eventually stream their movies themselves? Is the tech really that hard, why are they outsourcing it to Amazon and Netflix?

Like TV channels, we should just surf the studio websites until we find what we want (using Google, perhaps). That seems the inevitable future rather than one or two clearinghouses. That's what tech does: removes the middleman (except when there's a man in the middle ;).

For an adult human, 400-600 is about the limit of what we can detect.

No.

For most average human adults, the limit is about 300 dpi.

Speaking as a graphic designer with over two decades of experience, there is a reason that graphic designers have always targeted a print resolution of 300 dpi for colour images.

How 400-600 entered the conversation is beyond me. The percentage of people who can visually tell the difference between a 300 dpi output and anything higher than that is very, very small. The number of people who can spot the difference at 400+ is not even a consideration for discussion.

When I was a graphic designer, I was told 300 dpi --- unless the image had type, in which case, 600. I've found some corroboration:

1. Experiments with Pixels Per Inch (PPI) on Printed Image Sharpness by Roger N. Clark
2. Guidelines for Author Supplied Electronic Text and Graphics
3. Digital Art Guidelines

Apparently the eye is more forgiving when looking at photographs than at text.

"Legacy" is a buzzword for "old."

Multisyllabic and euphemistic, I'm sure it first came into being from the lips of an advertiser.

But if you want to think, write, and reason clearly about a subject, stick to the old, short words, the ones that your mind retranslates the words to anyway after hearing them.

There's also DaVinci Resolve and and LightWorks. Both with free Linux versions.

DaVinci Resolve is mainly for color tweaking but since version 10 also can cut. LightWorks has been used in Hollywood a lot.

In light of these two offerings, I'm surprised that PiTiVi is called the most mature. I haven't used any of them, though.

From the article:

It's a shame, because even though LCD tech has shown a lot of improvement, plasma displays have inherent advantages, primarily because the tech doesn't require a backlight -- unlike LCDs, which twist crystals in individual pixels to affect the light passing through, plasma pixels illuminate themselves.

And once big-screen OLED becomes cheap enough (OLED pixels, not just OLED backlit) then that advantage will dwindle away too.

Money is the root of all evil, and man needs roots.

Working...
