Comment Re:ZFS, Apple! (Score 1) 396

ZFS was a Sun project, and they've effectively killed it. Apple might have been looking at ZFS, but they never made it a part of their OS.

Shame, as it's a really nice filesystem. My previous file server was ZFS, and it was a delight. But it's kinda picky about what hardware it'll run on, and the old file server (dual Xeon) was just too power hungry to keep running at home...

To correct slightly - ECC isn't really about disk capacity. It's there because magnetic media isn't perfect, so even on a well written block there's a percentage chance of a read having a bit mis-read, and even on a failed read there's some percentage of good data read. The ECC lets the drive controller correct for those errors, so the vast majority of errors are corrected by the controller. A really smart controller or driver (GCC Technologies had this 20 years ago, perhaps they all do now) pays attention to ECC errors and re-writes blocks that have errors so that any marginal writes are rewritten with the user's data is protected before the block degrades to an unrecoverable failure, automatically. And if a read is so bad that ECC fails, you can re-try the read until you get a good enough read for ECC to recover the data, which almost always works, then rewrite it. If you do that, it's very, very hard to lose data on magnetic media, because it's nearly impossible for a block to go completely bad with no warning.

That being said, with the huge volumes of data that people use now, even a very rare percentage multiplied by that huge pile of data means they'll lose data. If you really care about that, you need to store your data on two physically separate devices, so a physical failure of one can't affect the other. This is expensive-ish, but that's the cost of protecting data. So an offsite backup is really the only solid option. Anything in your house can be affected by a fire, power spike, etc., so if you really care about the data, get CrashPlan or something like that.

No, in reality the IRS investigated all groups with political parties and movements in their names, since they're required by law (i.e. Congress) to only allow non-political groups to be granted tax exempt status. And the IRS investigated (and rejected) far more liberal groups than conservative groups. So (1) they were required to investigate political groups, so the investigation was not only proper, it was required by law passed by Congress, and (2) they didn't target Tea Party groups exclusively or even disproportionately.

So what were you complaining about?

I think you've hit on exactly the different between the two. Android feels like a computer in your pocket, where you deal with complexity (filesystem, memory management, APKs, etc.), and Apple's goal is to make it feel like a "smart phone", so they hide as much of the complexity as they can. Yes, the internals are similar (Mac OS X is pretty similar to Linux), but the difference is in how it all feels to users. And that's not just "prettier", but deeper - "does what I expect" and "it just works" and "easy to use" are important to most people, than the tech stuff that you think is "fundamental". To normal people, the tech stuff doesn't matter, except indirectly in that it enables the great user experience. So if you want a computer in your pocket, I'd agree, Android is a better fit. If you want a phone that is smart, that's Apple's goal.

As evidence that MBI might be right, there are several Chinese companies that took their open Replicator designs and crank out cheap copies, basically relying on MBI's design and software investments and selling at pure hardware cost. They're limited (legally) to using MBI's older designs, while MBI is attempting to innovate, and patent the innovations, to stay ahead of the cheap clones. And (amusingly) at least one of those cloner companies has now made enhancements to MBI's designs, and kept those enhancements proprietary, probably because they want a competitive advantage against smaller cloner^2 companies.

So the argument is that they patented it to protect them selves from the manufacturers who don't care about patents and will just make them and ship them anyway?

A cloner might not care about violating patents, but that's not the only factor, because the patents are enforced on import and within the markets. That is, if a cloner violates US patents, they can't sell product in the US, and the same in the EU, Japan, etc. So MBI, like the vast majority of companies doing engineering, files patents in the major markets (US, EU) so that if someone else blatantly copies their products they have legal leverage to stop them from selling into those markets.

This defense works in the real world. A few months ago, one of the cloners copied Makerbot's newer designs (the case design and control layout), and because MBI kept those proprietary, violating MBI's designs locked the cloner out of the US and EU. As a result, the cloner was forced to make their printer look different, and not identical to MBI's products.

The result is that, as I said before, companies that are cloning Makerbot's printers are using the open designs, or doing original work, because they don't want to get shut out of the US and EU. Copying open designs and making them cheaply is easy, they're good at it, and it's entirely legal so it's low risk. Copying proprietary designs is more work, and has more risk. Occasionally they try, but enforcement in the US and EU is effective in preventing cloners from blatantly copying proprietary designs.

Read the patent. It's not a patent on auto-leveling, it's a patent on using nozzle deflection to detect when the nozzle collides with something such as hitting a part of the print or for bed leveling. Bed leveling is properly disclosed as prior art. MBI's novel invention is using nozzle deflection (which their new extruder does) to detect collisions.

Really, you have to read patents more carefully. When a patent documents something as prior art, that's the opposite of claiming that it's your invention. Unfortunately the way patents are written is pretty confusing, but MBI's not claiming to have invented bed leveling, they claim to be first to use detecting nozzle deflection in 3D printing.

Yes, MBI started on an open platform (RepRap), then created proprietary aspects that they think give them a competitive advantage.

Most of them are minor, such as adding a bi-stable lever to the spring-tensioned extruder. But they didn't attempt to patent the community designs.

Most of the people freaking out are badly misreading the patents. That's not too surprising, since patents are pretty hard to read. But the parts where people are claiming MBI is patenting community designs are actually where MBI is documenting the prior art, which is exactly the opposite - they're documenting other people's designs because that's precisely what they're supposed to do, and they're not claiming those designs for MBI.

Don't propagate a misreading of the patents.

And MBI didn't "take" community ideas - everything that was open is still open, and MBI has contributed to open projects, and even started some open projects (e.g. Conveyor, Miracle Grue). And they strongly support open, shared designs, where they host hundreds of thousands of designs on Thingiverse for free.

MBI has been saying for years that they're making tools that are used by Makers, much like (for example) Epilog laser cutters. They don't feel that you can grow a large hardware company on purely open designs, because a competitor can come in that does no R&D and charge only for raw hardware costs and undercut on price, making the industry a "race to the bottom". So they keep open what they feel they can, and they keep closed the parts that they think protect them from "clones". You may disagree with their assessment, but they're being consistent.

As evidence that MBI might be right, there are several Chinese companies that took their open Replicator designs and crank out cheap copies, basically relying on MBI's design and software investments and selling at pure hardware cost. They're limited (legally) to using MBI's older designs, while MBI is attempting to innovate, and patent the innovations, to stay ahead of the cheap clones. And (amusingly) at least one of those cloner companies has now made enhancements to MBI's designs, and kept those enhancements proprietary, probably because they want a competitive advantage against smaller cloner^2 companies.

So you might prefer that MBI had stayed 100% open, and that's a reasonable discussion. There are certainly (smaller) companies that are purely open, and you'd perhaps be happier being their customer because you support that decision.

But when you make false accusations against MBI, instead of sticking to the facts, then it undermines your whole case.

There's not too much mechanical advantage in combining scanning and printing into once device, and they're too complex/expensive to combine because the combination would be too expensive and force users into bad compromises. This is different from 2D scanners and printers, because they're commoditized, so (1) the combination is cheap, and (2) you don't really care about the differences between specific scanners (or printers) because they pretty much do the same thing. In the 3D world, the different scanners (and printers) are very different, and they're expensive, so you're likely to research and select them independently based on your specific needs. Some day, when they're much more mature/commoditized, bundling them might make sense. But for now, it's too soon.

Laws apply even if you do things in your own home. And there are restructions on guns, as there have been for pretty much the entire history of the US. For example, it's illegal to make guns that are illegal for the general population to have (e.g. it's typically illegal to make a home machine gun). And it's illegal for you to make a firearm in your home (or sell one, or possess one) that can't be detected by a metal detector. Plastic or ceramic guns are illegal, and it doesn't matter how you make them.

"Comcast outright refused to accept more Netflix traffic from a 3rd party..."

As I explained, like many ISPs, Comcast caps or cuts off Cogent, because Cogent was violating their peering agreement. Search a bit, and you'll that pretty much every consumer ISP has cut off Cogent at one time or another. That's because Cognent hates paying for transit, and instead tries to use free peering transit..Peering only applies if there is balanced traffic in both directions, such as between two ISPs, whose customers send each other email, etc. If traffic is unbalanced, such as Netflix delivering tons of video to consumers and contributing no delivery capacity in return, then the transit has to be paid for. That's why all web sites pay for traffic, and don't get it for free.

So, as I wrote, either to fix the problem caused by Cogent, either Congent can either start paying for transit, or Netflix can use a more professional bandwidth provider. Instead, Netflix is trying to get the bandwidth for free from Comcast, with Comcast providing dedicated direct ports to Netflix, and Comcast is insisting that, like every other content provider, Netflix come in via standard bandwidth provider ports.

Exactly - home automation is in the complex/expensive/professional specialty market. Apple has the potential to take it to the easy/cheap/consumer market. Kinda like what they have done dozens of times over the decades - with laser printers, image editing, fonts, iMovie, iDVD and SuperDrives (a Mac with a SuperDrive cost 1/5th the cost of an industrial DVD burner at the time), iPOD, multitouch, mobile apps, etc., where they get it right as a complete end-to-end system that's consumer friendly and get traction where earlier players didn't. So it may not do everything the Crestron stuff does (their stuff is awesomely powerful) but it would presumably be nice and easy, not require a professional to do the install/configuration, etc., thus creating a consumer level home automation market that's (in unit volume) orders of magnitude larger than the current market.

But who knows, perhaps people will enter the home automation market, outgrow Apple's version, and become new high-end customers for you?
