Train Derailment Dumps Two 737 Fuselages Into Clark Fork River

Jeff DeMaagd Re:It is safer to fly (187 comments)

Airbus has many plants around the world building parts for them. Sometimes air is the best way to go. If it had to go by boat, you have a lot of money invested in airframes stuck on a boat for a month or two. Assuming you didn't need custom cargo ships, I don't think those fuselages can fit in a container.

Comcast CEO Brian Roberts Opens Mouth, Inserts Foot

Indeed, Comcast is trying to throttle people that use more than a third of a terabyte a month.

Official MPG Figures Unrealistic, Says UK Auto Magazine

Jeff DeMaagd Re:Real-world conditions (238 comments)

There are a lot of factors that affect fuel mileage, but it's been suggested that the ECM can detect whether they're on a standardized emissions or efficiency test and change the settings accordingly. I wish I remembered where I had seen that article.

Parents' Privacy Concerns Kill 'Personalized Learning' Initiative

Jeff DeMaagd Re:Good to hear there are reasonable parents left. (93 comments)

Well, knowing that amount of information about the children extends well to the parents.

The organization response does appear to be tone-deaf. I wouldn't care if they had perfect security. I care about what they're going to do with the information.

SpaceX Successfully Delivers Supplies To ISS

Jeff DeMaagd Re:Big day in Space (87 comments)

Without the glamor of our own human transport though.

Yeah, there's been problems, and there is increasing budget pressure. It seems NASA is the only government organization that actually get consistently cut. I kind of agree with Ares I getting cut, it was a boondoggle and suffing some problems that weren't well-publicized.

UK Government Pays Microsoft £5.5M For Extended Support of Windows XP

Jeff DeMaagd Re: TCO (341 comments)

I wonder if you're citing end of sales with OS X "died" dates, not end of support. End of support (updates, etc.) is different from no longer offering for sale.
For example, OS X 10.7 still seems to get security updates. Going by end of sales, Windows XP "died" June 2008.

Ars Technica just did an article suggesting that 10.6 isn't getting security updates anymore. The same article says 10.7 just got an update too.

So your figures for OS X might be exaggerated. That said, you're correct that XP has gotten unusually long support.

Functional 3D-Printed Tape Measure

Jeff DeMaagd Re:meh (134 comments)

3D printing is a pretty poor name. It's all additive techniques, of which there are at least six major types, I think. And they go from inexpensive hobbyist machines to over a million dollars.

They're useful technologies, but I think people are getting ahead of themselves. The focus should be on doing things that couldn't be done as well before, not making existing things, but more poorly and more expensively and thinking that's going to change the world. There are some uses though, tor example, I think GE has an turbine engine injector design that's now one piece instead of 23 pieces when done with conventional machining. In the GE case, it's a benefit, less complexity, less weight. Making a plastic tape measure with plastic tape, that looks like a waste of material & time.

Functional 3D-Printed Tape Measure

Jeff DeMaagd Re:Typical US creation (134 comments)

Yeah, metric drill bits are harder to find. I generally use number & letter gauge drills and just use the closest one. For my needs, the tiny difference is negligible. But I don't make aerospace & government parts, if so, then I'd use the specified size. A lot of cities seem to have a nearby machine tool supplier (there's two in my nearby mid-sized city), and they'll sell you just about any variation of metric tooling you want.

Functional 3D-Printed Tape Measure

Jeff DeMaagd Re:How long (134 comments)

The Peachy won't make that, it is too small.

The consumer accessible UV printers don't do flexible items yet. I don't know what method the Connex uses, I guess it makes sense it's UV. So it may be a matter of waiting for the material technology to go down in price. The current cheapest I've seen is the material costs $50 a liter for a rigid material, and that material isn't very good that I've seen.

Functional 3D-Printed Tape Measure

Jeff DeMaagd Re:Let me know when... (134 comments)

The technology is overhyped, A 3D printer makes you a product designer any more than a laser printer didn't made you a newsletter editor in the 80's.

One other reason I say that is when I see how fashion designers design their ridiculous stuff and "3D print" it. To suggest that people want to wear a fused plastic dress and call it high fashion is some serious encroachment on the story of the emperor's new clothing. Some of the items are a giant shoulder thing that might as well be an oversize tiara. Some of the works make the British Royal family look sane.

Outside of some niches, it's still mostly a rapid prototyping technology. That's what I use it for.

The Era of Facebook Is an Anomaly

Jeff DeMaagd Re:There can be only one. (260 comments)

Yeah, after a certain point, the network effect takes over. That doesn't answer how Facebook got to be big enough for network effect to dominate. Or maybe network effect started at the beginning, because it was school-by-school.

In fact, MySpace is only about 6 months newer, and I think was dominant for a while. It seems like maybe Facebook grew from people becoming dissatisfied with MySpace. I don't think we have seen a similar service growing considerably from dissatisfied Facebook users.

We used to have social centralization, the difference now is that there are a lot more choices. Decades ago, it might have been "everyone watching the same channel", a bit before that, "listening to the same station".

Time Warner Deal Is How Comcast Will Fight Cord Cutters

Jeff DeMaagd Re:LTE and 5G (424 comments)

Still, I'm not convinced that wireless will necessarily be a competitive solution to getting internet to the home, except as a second tier option.

Even if wireless can eventually get you 100x more data than current wireless, future fiber & cable will probably also be 100x that of current fiber and cable. Expectations & demands will probably scale up such that wireless might still not be good enough for home internet access except for a small segment of the population, or those that just simply don't have any choice. Already, I'm seeing comments from people saying that 6/1 Mbps is holding them back.

Time Warner Deal Is How Comcast Will Fight Cord Cutters

Jeff DeMaagd Re:LTE and 5G (424 comments)

Do any LTE services have reasonable data rates? The 5GB package from Verizon isn't going to take a whole lot of video use.

FTTH might help, but it might just be another duopoly situation.

Time Warner Deal Is How Comcast Will Fight Cord Cutters

Jeff DeMaagd Re:it's to fight the content owners (424 comments)

I think Netflix doubling prices was really just setting up Instant as a separate service. It's unreasonable to expect that the free, then later, $4 instant add-on was going to continue for too long. I wasn't happy with it though, so I dumped the discs.

They do lose content, but they also constantly add new. I imagine they don't have much choice without paying a lot more.

It would be nice if channels were unbundled, but I think that's just rearranging deck chairs on the Titanic. The idea of linear channels just seems increasingly antiquated. Yeah, there's live events, but the reasons for dedicating a specific band for them are diminishing when events can be streamed live.

Ugly Trends Threaten Aviation Industry

Jeff DeMaagd Re:COST (473 comments)

Yes. A new Cessna 172 Skyhawk probably cost $310,000 or more.

Even renting an older (though nice and very well-maintained) airplane is $90/hr, which at least includes fuel.

Some people kit-build planes, but that's a lot of work and it all has to be done and maintained right.

Insurance is expensive. Renting a hangar stall is expensive. Continuing education is expensive.

Regulations don't help, though there are low-regulation categories. Those are a considerably higher risk category because some of the people that take advantage of the lower barrier to entry are a bit more lax in doing things properly.

Learning to fly often isn't a good career move because pilots are now generally paid poorly.

One really has to want to fly badly, especially to give up several other hobbies to afford flying.

Customer: Dell Denies Speaker Repair Under Warranty, Blames VLC

Jeff DeMaagd Re:bad engineering? (526 comments)

I think you may have a mistaken impression of corporate structures. I don't think many corporations would allow electrical engineers have that kind of control unless said electrical engineer started the company.

I also doubt Lenovo or HP engineers would be in a position to point fingers, their consumer PCs aren't very good either, criticizing competition's build quality won't do them any favors when it invites reciprocation.

Clipping waveforms is a problem that can also ruin expensive speakers too.

ASCAP Petitions FCC To Deny Pandora's Purchase of Radio Station

I have nothing against the creators, but when one broadcast format gets preferential treatment over another, I don't see how that serves anyone.

I guess Taco and gang have added some interesting features without my realisation.

This is mostly a test. I am presently either avoiding work or waiting for a compile.

I am writing code for PIC chips. I have a nice box design for a linear positioner. It's not that accessable or useful for the general public, or geek public for that matter, but more for manufacturers that need parts cut to reasonably accurate lengths.

I have other ideas too, but I need to flesh them out before discussing them.
