[Disclaimer: I don't know anything about TiVo Series 2, what I sawy may be obsolete]
When I first got a TiVo, I hung around on some TiVo community messageboards. One of the boards solicited suggestions for new features, and "profiles for multiple users" was on the list of suggestions they'd seen plenty of times before, and didn't want to get again thanks.
It makes absolute sense to me for TiVo to support multiple profiles: if one person in the house loves soaps, and the other hates them, surely TiVo should be able to handle that duality of tastes? My guess is that TiVo never implemented the idea because they knew that MOST people would ignore the profile element. After all, the idea with TiVo is that if you like something, you hit "thumbs up", not check you're switched to the right profile, correct if required, then hit thumbs up. TiVo assumes you'll only use its features if the effort is minimal.
So I think they might be on the lookout for ways to implement profiles while adding as little effort overhead to the user as possible. By patenting this (unworkable IMHO) technology, they cement prior art for a variation on it using whatever more affordable, practical derivative of RFID comes along next.
Companies use automated systems because it's cheaper than having enough real people to handle it.
So, you'd rather get straight to a real person. Who do you think's going to pay for that? Will they absorb it out of their profits, or pass the cost onto customers? I think I can guess.
Yes it's a PITA, but it's the price you pay for cheap goods.
(This doesn't explain why Apple does it of course;P)
If you want to use Apple's music store or store music on the ipod, then you have the responsibility of making sure what you purchase or use works.
I think this is backwards.
"I want to use iTMS, therefore I must use compatible devices" is an odd direction to go.
"I want to be able to play my media on devices x,y,z, therefore I need a source of media which plays on them all." seems more logical to me. For many people, iTMS is unlikely to be that source.
Marketing is encouraging people not to think too hard about this. If Joe Nontechnical buys an iPod, he'll install iTunes, and may well end up buying some songs from iTMS. If he later buys an Xbox 360, he may reasonably expect to be able to play his songs on there: but he can't.
As for UMD, well I have no idea why anyone would buy a UMD movie. If you must watch movies on a teensy screen, rip a cheaper DVD to memory stick.
The problem with this, and similar DRM workarounds, is that since the vendor doesn't have visibility of your cracking, the message they get is that consumers are happy with DRM.
I vote with my wallet. When someone lets me buy the music I want, in a sufficiently open, conveniently transcodable format, for an acceptable price, I'll give them my custom. Until then, I'll keep buying CDs.
To summarise: Wind power does require more backup building, unless it only makes a trivial contribution. The article you quote tries to dodge issues more than address them.
It depends what you consider trivial. The article I quoted is talking about wind as a source of 20% of our needs. I think most of the arguments against probably break down when you're only talking about 1/5 of the total supply, but organisations such as Porritt's renewables commission find themselves having to argue hard even for that.
So then I'm thinking "if we have a giant powerplant tethered securely to teh seafloor, why not put the turbines UNDER the water and harvest energy from tidal movements rather than wind? Surely there's more to be had there.
Congratulations on inventing offshore tidal turbines. Although I do wonder, if you're building something out at sea anyway, and running a power cable to it, why not pop a windmill on top for good measure?
Much is made of its intermittent nature, but wind is more predictable than people assume. Advanced forecasting makes wind output from across the country much easier to anticipate. Bearing in mind the huge minute-by-minute shifts in power supply and demand, wind is just another cog in the system.
Jenkins claims that wind will require "dedicated backup", but this is not the case - and our view is supported by the National Grid, which runs the electricity system. Dedicated backup is not required for wind because backup supplies are provided for the whole electricity system, not for each individual plant. If this weren't the case, we'd need backup for every plant in the UK: nuclear and coal also have unplanned shutdowns, and when they do the effect is more dramatic than for wind.
So to summarise (or paraphrase, if I get too verbose):
Wind is indeed intermittent, but (demonstrably in the UK, Porritt's commission published a study; and surely in somewhere as large as the USA) it's windy somewhere almost all the time. The purpose of the grid is to flatten out regional variance in supply and demand.
Yes, backup is required, but this applies equally to other sources.
One server running 10,000 virtual hosts is 10,000 "sites".
This is why historically thttpd did very well in Netcraft surveys -- it was good at hosting thousands of sites from one server (and allowed throttling of over-used sites).
Personally, I'm more of an iPhoto kinda of guy, since my personal foto lib is about 3K (I like to take pictures), it does a good enough job.
I found that iPhoto lacks "teh snappy" (as I gather Mac people like to call it) with my ~5,000 photo collection, whereas Picasa on lower spec hardware manages with ease.
As for Dvorak's whining, I use Picasa to tune my photos -- that gives me approximately 20 things I can do to an image (depending on which ones you consider to be part of the same "thing"). If Picasa won't do it, I break out The Gimp, but that's hardly ever necessary.
The feature that looks most interesting to me is auto-indexing of every page visited, and the Beagle/Spotlight-style history searching that makes possible.
There's no way you could evaluate that in 10 minutes.
And you/did/ see all those reminders that this is a developer release, right?
That's interesting, and I consider myself newly educated, so thanks!
But based on your description, the Torah clock overflows to zero once a year, so it does not embody the Long Now as the 10,000 year clock intends to. In order to do so, ever Simchas Torah a counter would somehow need to incremented.
A sundial, like a conventional clock, overflows to zero every day. Hillis wants us to think of tomorrow, not just today.
32 bit UNIX time overflows every 136 years. Hillis wants us to think beyond 2038.
64 bit UNIX time won't overflow for 290 billion years, but any computer currently in operation will stop working, or at least lose power eventually, and Hillis wants us to think beyond the lifetime of a conventional UNIX box.
Plus, of course, a little computer with a screen hasn't the majesty Hillis envisages. RTFA:
Hillis's plan for the final clock, which he reserves the right to change, has it built inside a series of rooms carved into white limestone cliffs, 10,000 feet up the Snake Range's west side. A full day's walk from anything resembling a road will be required to reach what looks like a natural opening in the rock. Continuing inside, the cavern will become more and more obviously human made. Closest to vast natural time cycles, the clock's slowest parts, such as the zodiacal precession wheel that turns once every 260 centuries, will come into view first. Such parts will appear stock-still, and it will require a heroic mental exertion to imagine their movement. Each succeeding room will reveal a faster moving and more intricate part of the mechanism and/or display, until, at the end, the visitor comprehends, or is nudged a bit closer to comprehending, the whole vast, complex, slow/fast, cosmic/human, inexorable, mysterious, terrible, joyous sweep of time and feels kinship with all who live, or will live, in its embrace.
And as for practicalities -- like much conceptual art, the idea is more important than the implementation, yet the implementation has to exist in order for the idea to carry any weight. There's no point spending time in a gallery perusing Duchamp's urinal; it's just a urinal. But had he not put that urinal in a gallery, had he instead just said "Hey, if I just put a urinal in a gallery, would it be art or not? Clever huh?" and not followed through, I wouldn't be talking about it now.
I know a clock that's been running for 3500 years. In fact, in a week or so, we wind it with a beautiful ceremony. Millions of people around the world will participate in the winding of this clock, and similar numbers meet several times a week to read its instructions, and wind it throughout the year.
It is, of course, the Torah! ...
Hillis just stared at me like I wasn't making sense.
I'd have done the same. Maybe, like me, his religious education never covered the Jewish religion. That Wikipedia article doesn't tell me why the Torah is like a clock, nor do I know what winding ceremony you are referring to (my desk calendar lists many religious days, such as Yom Kippur and Ramadan, but there's nothing there until Halloween).
So your "of course" isn't so obvious to me, Hillis (apparently) and millions of others unschooled in your particular religion.
You've piqued my interest though, so I'd be keen to read your explanation. If it's a conventional interpretation of the Torah, perhaps you should update the Wikipedia article...
The new series was good, but plagued with ambivalence. On the one hand, the Doctor makes jokes and the soundtrack plays the occasional circus melodies. On the other, he's a dark, damaged bugger of a Timelord (who may or may not have designs on his impressionable young companion), there are scenes of torure, talk of prostitutes...
I agree with your assessment, but I see it as a blessing not a curse.
Ambivalence and ambiguity were the show's great strengths -- art, like life, needn't be black and white.
That heady mixture of the light and dark is also what made the last series of Doctor Who such a great return to real Saturday afternoon family viewing. There were laughs and scares for the kids and idiots, and usually something subtler for intelligent adults. Brilliant.
In the UK, "Continuing Education" refers to part time education taken once your full-time education (school, university etc.) is "complete" (not that you can't return to full-time education).
i.e. evening classes, etc.
However there is usually some element of credit, however mickey-mouse, because the government will subsidise courses if you get some sort of accredited certificate at the end.
This is why I have three pieces of paper indicating that I learned a very small amount of Japanese over the course of 30 1 hour evening classes...
Yes, Acronym Finder lists a number of meanings, none of which is "Canada". The first meaning that leapt to my mind was "Campaign for Nuclear Disarmament".
Canada's not such a long name to type anyway, now, is it?
If you want to use cutesy abbreviations, how about the ISO country code (CAN).
Usually a good idea, although be careful with the UK -- the ISO code is GB, but you might upset unionist Northern Irish if you use it.
The use of "GB" for "The United Kingdom of Great Britain and Northern Ireland" surprises some people. However, the United Kingdom and the Ukraine both wanted "UK" so rather than start World War III over the matter, the United Kingdom was assigned "GB" and the Ukraine was assigned "UA.
Personaly Im realy impressed by Ikea and their instructions.
Me too. I've put together quite a lot of flatpack stuff in my time, and in general Ikea's is by far the best designed and has the clearest instructions. Parts are often designed so you cannot put them in the wrong place (cf. all the differently shaped connectors on the back of a PC).
I always use a hex bit in a socket screwdriver to assemble flatpack furniture. Recently, fixing metal leg attachments to a TV bench, I was perplexed to see that the instructions wanted me to tighten two screws in most of the way, then position keyhole-shaped holes in the leg attachment over the screws, then tighten the screws the rest of the way. Why not just push the screws through normal holes into the screw-hole in the conventional manner?
Then I realised - if I'd been using the allen key provided, the legs would have prevented me from doing a full turn of the key. Ikea's designers had specified keyhole shaped holes in the leg attachments so that allen key users wouldn't get frustrated. THAT is attention to detail.
I'm also always impressed at the way they constantly refine their designs to shave off every last wasted penny. By moving house a lot, I've bought various configurations of Billy shelving, and I've noticed that as time goes on, fewer and fewer of the chipboard surfaces are laminated. By the time the unit is built, of course, the unfinished parts are always out of view. It's efficient and (in an engineering sense) elegant.
Ikea's cheapest products can be a bit shakey -- that's why they're so cheap. Spend a little more and you get terrific quality for the money.
(I speak of Ikea in the UK -- I don't know how prices or product lines are in the States).
I've played wiht Linux on 500MHZ cpus, Linux crawls on this
Good lord.
My first Linux machine was a 486 SX25. I developed and wrote up my final year BSc project using it. It was fine.
Even now, the Linux machine on my desk is a 233MHz Pentium (my employer tries to keep our "primary workstation", which needs to run Windows, up to date. Anything else we have to scrape together wherever we can find it). Firefox is sluggish -- I admit I use Dillo if I need to use this box for Web stuff -- but it's more than adequate for lightweight apps and as many xterms as anyone could want.
Customising a distribution for a 500MHz machine would not be all that challenging.
Guaranteed way to make Linux Panic every single time: Put/lib on a separate partition during the install.:)
It's not very interesting to make Linux panic every single time though -- especially if it will reliably panic during boot.
To be a real headache in production, it needs to panic intermittently and unpredictably. In my experience, that only happens if you're running a kernel from the unstable tree, or you've got hardware problems.
My local non-league football team (association football, that is... OK, soccer if you like) has a bloke who films every match using a camcorder, and produces DVDs for harcore fans (of which there can't be that many: 800 is a good home crowd).
I've not seen the DVDs in question, but it seems to me that producing adequate footage of a football game from a single vantage point, zooming and panning on the live action, must be quite a challenge.
It occurred to me that with a very high enough resolution CCD, and a very wide angle lens, one could capture the whole game using static cameras, and pan and zoom in post-production. With a few of these (which could run unattended) you could get very good coverage of a live event, deferring all decisions about zoom levels, pans etc. until afterwards.
What's that you say? Off topic? Er, OK. While a 360 degree capture might not be appropriate for a sporting event (unless you were also interested in capturing the crowd -- since the camera couldn't be in the middle of the pitch), you could use the same technique in other circumstances to capture an event then edit it down afterwards.
As an Emacs user, I agree. Emacs has brain-dead defaults. To get usable keybindings, you have to do it yourself. OTOH, when you do it yourself you get keybindings customized to what YOU do, not some one-size-fits-all-but-not-that-well least common denominator keymap.
This is intriguing, because it might give me an excuse for failing so badly when I tried to learn Emacs:)
But: (1) Designing a set of keybindings is quite a challenging task in itself (2) Doesn't this mean that if you try and use Emacs on a system other than your own, you're stuck?
Yes, because typing L to go right, K to go up, J for down and H for left is so much more logical than ^F for forward, ^B for backward, ^N for the next line and ^P for the previous line! (I realize non-English speakers will be hosed either way.)
They're nicely lined up around the right-hand home key, whereas the Emacs movement keys are all over the place and require you to hold down ctrl.
Maybe this is why RMS got crippled by RSI?
Admittedly the normal cursor keys work in every version of Emacs I've tried. I tried to learn using CTRL-L/R/N/P because I assumed they'd been chosen for a reason, and maybe that was my mistake.
