Re: @DryBones yes, yes, that's all very well
Huh. DryBones deleted their post! Oh well, just as relevant to the OP of the "yes, yes, that's all very well" thread.
@DryBones Re: yes, yes, that's all very well
The problem with mp3, the DVD formats and many, many other restricted formats is that they are, well, restricted.
The very nature of Free Software, whether you are talking about free-as-the-air or free beer, is that it is either free of restrictions or free of charge. This means that the distro suppliers won't (in the case of as-the-air) or can't (as in beer because they can't afford it) put the support for restricted formats by default.
Blame the people who foist the restricted formats onto us all for this problem, not the distro suppliers.
Of course, earlier releases of Ubuntu often would tell you exactly what you had to do so that you could make the personal decision to break the licensing conditions or patents on the codecs that the distro supplier cannot make without opening themselves up to being dragged through the courts.
It was not that long ago that Canonical were being slated by the '-as-the-air' community for paying for licences for H.264 just so they could include it for people like you.
I know that this does not help you, but that is the nature of the world we live in. Would you pay for a version of Ubuntu or any other distro (so that the supplier could pay the license fees) that included all the codecs you need?
I'll give it a go
I will put this on a partition of my laptop, and boot into it occasionally to see how it is doing. If I can cope with Unity (although from current experience, I won't), I will switch over.
But the problems I had with Lucid stopped me from switching permanently from Hardy until they pulled support from the desktop release of Hardy. Even now, there are significant things that don't work on Lucid, despite defects being open in the Ubuntu fault tracking system.
I have Unity as the presentation layer on a netbook running 10.10, and also on a desktop running 11.10. Later releases may work better than earlier ones, but that does not alter the fact that I believe that it is less suited than Gnome 2 for people who work with multiple overlapping windows on several desktops. I can see it working well for the Mac OSX generation (single application occupying the whole screen most of the time), but that's not me. That way of working is just alien to the way I have worked since twm on X.10 or SunView. I want drop down menus attached to the window I am working on, not up at the top of the screen.
As for HUD, I've not played with it. It may be helpful, but it sounds to me like it will tie applications into the Window Manager in ways that will be detrimental to application portability, which can never be a good thing.
Re: I got one for automation
And the sad fact is that the people who are made to leave are often those that understood the automation, so as soon as something changes, the automation breaks and nobody knows how to fix it, so it becomes a manual process again.
About 7 years ago, I was part of a project automating the build of servers (IBM Power 5 servers running AIX) in a server farm. Could deploy an OS image on a virtualised machine with all patches, management and security software (and some frequently used application as well if required) installed and registered in about 40 minutes from bare metal to hand it over to the application installation team. Did all the work from base packages, no Golden Image in sight. Brilliant (and also stunned IBM when they came to see what we were doing!)
Came back to the company a year and a bit later, to find that the people running the process were all low skill process monkeys who had reverted to manual processes when new machine types came along, and they did not know how to tweak the process (even though it was fully documented!).
Broke my heart!
You needed a BitStik!
Put thrust on the twist of the joystick and had three buttons. Made complex manoeuvres less like shaking hands with an octopus!
And when you ran Elite on a 6502 second processor (if you bought a BitStik, then you probably had one of these as well to run the CAD software), you got Mode 1 graphics and none of the 'mode change' interrupt tear when it switched from Mode 4 and Mode 5 3/4 of the way down the screen.
Did you have a GT40 and Lunar Lander as well? First McDonalds on the Moon!
If it really does not have an analogue tuner....
Or, find an old video recorder (with an analogue tuner), and use that to map tuner to a SCART connector on the TV.
What! No mention of the Plus One
This plugged into the expansion slot, and provided the Microdrive interfaces, along with a joystick port, a serial port and some strange network which allowed you to link several similar systems together in a peer network, sharing the microdrives.
My father bought an early 48K system (I had a bought my own BBC model B), and it did indeed have light grey keys like the picture. In addition, it had the 32K add-on board, and also had a heat sink that ran the entire width of the system under the keyboard, leading to a warm programming experience.
I never really liked the Spectrum, it was too slow, had poor sound, the screen attributes just felt clunky, and that keyboard!
My Beeb, although supposedly lacking in memory, was just a class machine, and ended up being used for things you just could not consider using a spectrum for. OK, it was not suited to large dungeon type games, but I would contend that Snapper, Planetoid, Meteors and Arcadians were great copies of arcade games that the Speccy could not hope to match, and Freefall, Starship Command and especially Elite showed what you could actually do even with a supposed lack of memory.
But the Spectrum was an influential machine, no doubt.
A PDP 11/84 was a single-chip PDP 11 processor (J11?) in a minicomputer rack (it had a UNIBUS rather than a QBUS which made it a proper PDP 11 rather than a micro PDP 11 like the 11/83).
It was definitely *NOT* a mainframe, but a 16 bit minicomputer with address extension. IIRC, it probably was the most powerful of the whole PDP/11 family (I mean real PDP 11 rather than a VAX 11).
This 'new' ability to only run Linux is not new. If you have access to a Power 6 or Power 7 system, and look in ASMI or on the HMC (and I presume SDMC and IVM) at the entitlements section, there has been an entitlement for both AIX and IBM I for several years. Linux has been an officially endorsed OS by IBM on PowerPC for at least 7 years (they have had agreements with Slackware and SuSE), and there are official distributions of RedHat and Ubuntu from those companies.
This makes this a re-announcement of an existing policy, probably to remind some existing PowerPC shops that they can stick with Power rather than moving to another processor, even if they are switching OS. I very much doubt that the product announced will significantly differ from other systems that will still run AIX and IBM I.
This does not give any new reinforcement that policy that you bring up in every discussion about PowerPC or AIX. Both AIX and PowerPC will be here for some time still. That link lookes older each time I look at it.
Now. I'm not going to argue with the fact that AIX (along with all proprietary UNIX systems) is on the downward side of the popularity curve, and I do not think that PowerPC development is in a good place at the moment. It's expensive to build new generations of any processor, and I think that IBM is really thinking hard about what to do with the PowerPC line, at least in high end servers. Sometimes I wonder whether IBM really wants to remain in the hardware business at all (products that have been sold include their printer division, their storage division, the desktop and laptop PC business, and most recently their ATM and PoS business).
This policy may extend to their server systems as well. Power7+ is late according to previous product roadmaps, and there is strangely very little pre-announcement information about Power8. IBM has also made statements that their previously loss-leading HPC work has to become more commercial (probably one of the reasons why IBM pulled out of Blue Waters), which means that future generations of IH HPC systems are at risk.
But one of the effects of there being a creditably competitor to Intel processors is that makes Intel aggressively pursue new processors. Once they are only competing with themselves (remember, AMD need chipfabs like IBM to create their products, because they cannot fabricate processors themselves), then the rate of product development will slow significantly, as Intel would want to get more return on their investment.
I am really not looking forward to a point where the only processor game in town is X86 derived, and that is looking like a possibility within a decade unless ARM moves upward.
Re: where the buck stops - AC
it depends. If you have decided to include a software product that needs escalated privilege (root or admin), then that is not Microsoft, and you must take some responsibility yourself, and should also blame the vendor of that package.
If it is software that does not require escalated privilege, and can get it using the package, then that would of course implicate Microsoft as well.
But in your example, it would be better to ask if Microsoft should take any responsibility for something they include from a third party as part of a windows installation (such as the CD and DVD burning code licensed from Roxio), as this is more like what Linux Distributions do.
Am I alone in remembering Red Box...
a company formed by Hermann Hauser in 1985. I know it's since disappeared, but it marketed a through-the-mains control module solution.
I can find almost no references to this in Google, Wikipedia etc. It's amazing how something used to be able to disappear almost without trace before the Internet.
Dell and terminals
"never made a machine that needed a dumb terminal" - this is untrue.
Dell had a brief foray into the UNIX on Intel world in the late '80s and early '90s with systems running SVR3 and SVR4. These systems were shipped with multi-port serial cards, so would have used terminals of the type produced by Wyse.
I can't remember what they used to call them, but I attended an interview for their UK support team. I also can't remember what the outcome of the interview was, but bearing in mind that the team was wrapped up not that long afterwards, it was probably better that I did not work for them.
Re: Surely this is illegal
Illegal? No, certainly not under the Data Protection Act. The employers are asking their prospective employees to volunteer their facebook account details. If they agree, then it is a private agreement between the individual and a company. This is exactly the same as a loan company asking for copies of your bank statement before offering a loan.
It may be counted as discrimination if it can be proved that the individual did not get the job because they refused to hand over details, but that would be a completely different issue.
I immediately thought that the employers were going to turn an applicant down if they actually DID give their login details over, because that would indicate a lack of understanding about on-line security! Ho hum.
@Chemist Re: So what /should/ have been done?
Reminds me of the old IBM PC error "Keyboard error - Press F1 to continue"
The old ones are the best!
11/780 was the base.
When the IBM PC was launched, remember it was a 16 bit processor in an 8 bit system (8088 had an 8 bit multiplexed data bus needing two cycles to store a 16 bit word), and was only clocked at 4.77 MHz. In the Personal Computer World BASIC benchmarks, the BBC micro could whip the ass off the IBM PC in performance terms, although this should not be a suggestion that Linpack results would be the same.
I always regarded an original 6MHz PC/AT as about the same processing power as a PDP 11/34, although that was only on a subjective feeling, and a VAX 11/780 was much more powerful than my 11/34.
A real supercomputer is a lot more than just processing power.
The current systems I am working with (still on the top 500 - just) are split (very approximately) equally cost-wise between processing, networking and storage.
The interlink is important for massively parallel jobs, and there is no point in crunching numbers if you can't store the results. Linpack can be a very misleading benchmark.
Re: Re: Server-Side Copy
Yes, if you are able to make one NFS server talk directly do another, without using a client computer. But I think that if you use SCP with two remote locations, the data still travels through your local machine, in-and-out.
I miss being able to go into an arcade and spend an hour or so bashing steel balls around a table. It's a great way of letting off steam. I used to be able to get a replay on my regular tables almost every game, which made it quite cheap! Oh, the feel of the flippers and the buffers and kickers...
Every now and then I will find a table in good enough nick to be worth playing, and I still have some of my skill. I went into a pub a few years ago with some friends, saw a table that I had never played before, and still managed to get two replays from the 50p I put in. Pissed off my mates who thought I must have been in before.
I live in a tourist oriented seaside town and I cannot find a single table worth playing here. It's sad really.
200 miles per day
I used to commute 96 miles each way daily for over three years. It's not that unusual. I currently have a 'short' commute of about 45 miles each way. And when was the last time that you left on a journey without any means of refuelling with less that a 25% margin or error? Who knows when you will get stuck in traffic/diverted? I certainly would not want to do more than a 150 mile journey in a car with a maximum range of 200.
Also, 200 is when it is new. How will it work after a years worth of daily recharging?
Re: make greater use of probabilistic information in their weather forecasts
The way the weather is presented in the media is controlled by the media, not the Met Office.
It's true that some, like the BBC, actually use Met Office forecasters, but the presentation style is normally controlled by the broadcaster, not the forecasters.
If you want to see isobars, look at the Met Office web site (try the link http://www.metoffice.gov.uk/weather/uk/surface_pressure.html directly), not the forecast on the telly.
Re: Helps if you actually forecast
Try the localised detailed forecast from the Met Office's web site, rather than relying on some summary forecast where the poor forecaster has to cram some approximation of the weather for a region the size of several counties into a few 10's of seconds.
You might as well try to describe the colour of London as seen from Google Earth in 10 words or less.
Version numbering and catchup
I agree with your comments on version numbering. There is not that difference in the outward appearance of AIX 5.3 and AIX 7.1. Under the covers, there have been quite a lot of changes, including dynamic partition migration, more control of WPAR isolation, support of more logical CPUs, USB storage support and up to 4 threads per core.
A lot of the changes are targeted to the very largest systems, but this is not really a problem because what features that you need are not in AIX already? I'm not including things like Gnome and KDE, because they are not really part of the OS. DBUS maybe? Remember that AIX has never really been a desktop OS, and much of that Linux innovation has been in things that are really applicable to personal systems rather than servers.
I don't rate your comparison of AIX and Ubuntu LTS. In the same time I have been working with AIX 5.3, I've gone from Ubuntu Dapper Drake (6.06), Hardy Hedgehog (8.04), and Lucid Lynx (10.04).
IBM have always clear about the lifetime of it's OS products. End of marketing is always announced at least a year before it is actually withdrawn (and normally soon after the +2 version is announced), and there is normally at least a year of support from End-of-Marketing to End-of-Support, and then there is always extended support for customers prepared to pay. And after that, the mature AIX product (which after so long in support is likely to have had all of the serious problems fixed) will have the fixes available on fixcentral for a couple of years more.
Re: Related to ongoing contracts that are late and run on AIX 5.3 perhaps
PTF stands for Program Temporary Fix.
AIX 5.3 was actually released in 2004, and the product lifetime cycle published on Fix Central has indicated that TL12 would go out-of-general support later this year as early as this time last year.
This means that AIX 5.3 will have had a lifetime of over seven years, and if you take into account extended support, will be more like 9 years.
TPM's article has several errors in it to do with dates and functionality of earlier versions of AIX (like LPARs being introduced in AIX 5.1). I've sent a correction, so we will have to see whether the article is fixed.
SciFi got there first
Larry Niven based the whole of one of his literary universes around a society who 'harvest' body parts from convicted felons. His conclusion was that eventually people would end up being broken up for offences as serious as jay-walking and tax evasion.
Look up "Flatlander" or "Gil the Arm" if you are interested in reading the stories.
Only those destined for the Chinese internal market. Anything sold in other countries would be subject to cases in each country in question.
Of course, in China anything could happen, given that their legal system is very different. But I think that many companies would re-consider using China as a manufacturing base if the Chinese authorities were to start confiscating goods destined for sale outside of China.
Money going back?
Who said anything about money going back?
This is all about money they have spent that has not resulted in payments coming from the customer. Still a quite good thing from the NHS's point of view, but I'm sure everyone really wanted a working, applicable system developed within the budget.
Still, not sure whether that was ever possible.
Not sure if you are still reading, but I am a sysadmin using LTO tapes in my daily life.
Even if the tapes are still readable in 30 years time (debatable), are you still going to have a device that will read them reliably in 10 years? In my time as an admin (~30 years), I've used 1/2" mag tapes, DecTapeII, QIC cartridges, 1, 2, 5 and 20GB 8mm Exebyte, 4mm DAT, DLT, IBM 3840 and 3570 cartridges, and even Sinclair Microdrives. All of them are now obsolete, and I would expect that of all of them, you would probably have better success finding someone who could read 1/2" tapes than any of the other formats. LTO says that it will read and write current generation and last generation tapes, and read one previous generation, but that is all that is guaranteed.
Also think of floppies. Remember 8" floppies? I still have some (out of nostalgia because I can't read them). 5.25", 3", 3.5". All dead. Jazz drives and the others. Gone and mostly forgotten.
Disks are no good either. ST506 Shugart is dead. ESDI is dead. Older SCSI is dead, IDE and EIDE are dying, even the older SATA disks will not be able to be connected at some time in the near future.
My view is that CD and DVD still have some life left in them as backup. I just wish I could trust them more.
My rule is...
...put it on a hosting site for others to see and for my convenience when I am away from home, but keep my own copies it on the most persistent media I can find. For extremely valuable information, keep copies outside of the home as well! Unfortunately, what counts as a persistent media at the moment. I'm finding writeable CDs from the late 90's are already becoming a bit dodgy.
Having said that, I must backup my laptop. Ho hum, I'm busy, so that will have to will wait for another day(!)
@AC re: "Perfectly useable"
I still power my Palm Treo 650 up and marvel at how much easier it is to do so many of the day-to-day things than any of the smartphones I have had since. Granted it is not as powerful, and is not a 3G device, but it does (with some added apps I admit) 80% of what I do on my current Android. And the battery lasts close on a working week with light use, even after 7 years.
So much so that it is still in my bag, charged, with a PAYG sim in it as my backup phone.
Shame it does not run Angry Birds, though!
@Marvin re:R is an emulation of S
If there are any R proponents here, I'm sure they will dispute this. R is indeed a re-implementation of S, but it has evolved hugely. AFAIK, development in S stopped sometime in the mid 1990's (I was using it in about 1987). I don't even know if S is in the AT&T Toolchest any more.
Of all of the tools listed in the OP, R/S is about the only tool that covers a significant proportion of what Mathematica can, and is the only one that can (creditably) claim to have pre-dated it. All of the others have been produced for part of what Mathematica can by those who could not afford it.
The only other thing that I came across that was used to do similar things was SPSS, but that was originally not a package in itself, but allowed you to do data manipulation more easily from inside other programs. I think that it has changed since I used it in 1980!
There's other problems here
Many users will transition from XP directly to Windows 8 when MS finally convince people that older versions of IE are insecure, and they nagware that is Automatic Update starts shouting that there are no more fixes even to SP3.
So what some commenters here are seeing as incremental change XP->Vista->7->8 will appear like a big-bang.
I personally cannot abide any interface where I have to drill down to what I regard as the root window in order to open something new. I want and need something that gets out of my way when I am not using it, but can be called up when I do. I tend to set autohide on any/all UIs that I use, and run with several overlapping windows on multiple virtual desktops obscuring any 'tiles' or desktop icons. This is one of the main reasons I don't like Unity and probably won't like Windows 8 if this article is correct.
Looks like I am condemned to be a technical dinosaur, at least as far as mainstream UIs.
@AC re: House of Lards - A heriditary house?
Probably not, but a second chamber, quite definitely.
But most of the hereditary peers were removed from the house by the last administration. Those peers that remain are selected life peers who have been elevated for their contribution to the country, and society as a whole (or at least that is the aim). As a result, they are supposed to be respected, and as such are given some power to ask the government to reconsider prospective legislation, which is a good idea.
The real problem is that although a second house is a thoroughly good idea, it must be disconnected from the House of Commons by having a completely different selection mechanism. There is no point in making it elected in the same time-scales as the lower house, because it then becomes just a rubber stamp body, reflecting the same issues that were in vogue when the election was held.
I for one feel that a house selected by merit is a suitable system. Maybe there should be a time limit on how long members of the Lords should be allowed to remain, but if the AC actually bothered to watch Lords debates on the BBC Parliament channel, then I think that they would be surprised about how interesting and well informed some of the speeches are. I was particularly impressed by a seemingly old foagy (can't remember who it was, I really should find out) standing up in the Lords during the ID card debates and making one of the most reasoned and interesting 20 minute contributions to the debate that I have ever heard. Changed my perspective completely.
I read the sentence about Beats and Bose, and just had to hit the upvote!
In addition to all of your thoughts, I'm pretty worried about what pocket lint will do to the volume slider after a few weeks.
The upgrade stats will be skewed
because there are more users of older iPhones who will probably want another iPhone, and rather fewer Android users from the same generation who are actually be in the position to upgrade.
It may also be that the users of Desires et. al. are still happy with their phones, and see no reason to upgrade.
Run the survey again in a year to 18 months when more of the older Android phones become obsolete (not able to run beyond FroYo), and see what it says.
Interesting thoughts about PCIe, but by exposing the GX+ bus on almost all of it's models, IBM has had the ability to side-step some of the bottlenecks associated with slower I/O buses.
Of course, this does require having suitable adaptor cards, but if you look at the P6 IH (P6 575) supercomputer nodes that IBM sold three years ago, the main interconnect was provided by 2 quad Infiniband cards plugged directly into the GX+ bus to give these systems the required grunt without having to use PCI or PCIe cards.
The downside of this is that you are forced to buy whatever offering IBM has, because very few third party hardware vendors will actually be interested in the investment required to produce such cards.
changing your handle will make a difference for moderation. The mods will identify the account by the login name, not the handle.
I don't know what their policy is on registering two accounts against different email addresses. I thought I read somewhere that it was either discouraged, or maybe that it was enough to get the accounts suspended.
@madra - Hope this was meant in a light-hearted manner!
So you're wanting to ban some of the non-English first language commentards, as well as those not as educated as yourself?
Whilst I find it difficult to read some of the comments written in poor English, I have known many people with very valid technical information and comments who do not have English as their first language. I think I can put up with poor grammar so long as the comment has substance.
I think that those who use bad grammar as a reason to shout down a comment they don't like is just as bad as gratuitous use of poor English.
If your comment was tongue-in-cheek , then might I suggest that you use the Joke Alert! icon, rather than the Troll icon.
I feel the registers forums have lost something
I just wanted to point out that I had a visible (on the forums) conversation with the The Register's then most celebrated moderator about having the reason for comments being rejected made known. What has been detailed in the new rules may go some way to getting what I asked for. IIRC, Drew was also in on the exchange, which should still be visible.
I didn't have to mention The Moderatrix's name, but I wanted to express my continued feeling of loss of the witty banter that typified us the commentard's collective exchanges with her.
Does this mean that we may get some feedback about why some comments are deemed unpublishable.
I had a long exchange with Sarah on the last comments rule article about wanting to be told why some comments were rejected. I try to self moderate, but I do have comments rejected on an infrequent basis.
I know that what you have said here is not quite that, but it's a step in the right direction IMHO.
I miss Sarah. It's just not the same trying to bait the rest of you to jump into a comment trail!
I have temporary custodianship of one of these while I try to get the calibration of the screen correct for Ubuntu.
It uses the FinePoint driver (which has, unfortunately, been pulled from Xorg's source tree now), and I cannot get the scaling and offsets to make the pointer accurately follow the touchscreen. And no, the documentation about the values to put in the xorg.conf and the sample calibration utility do not work as the documentation says (at least for this system). I can get the offsets set correctly for the top left of the screen, but the scaling makes the pointer fly off the right and bottom sides with minor movements regardless of the numbers in the configuration file. It looks like there may be an overflow or a divide by zero in the offset calculations in the driver going by the errors in the xorg.log file. I've not had the chance to look through the source yet. If anybody has any ideas, I would be interested. Ubuntu 10.4 (the last release with the touch screen driver in Xorg) also cannot drive the nvidia display correctly with hardware acceleration turned on.
Unfortunately, even if I get it working, it's still unreasonably slow, with the example I have it's got a 1GHz Transmeta Crusoe processor (which is another interesting point about this machine), so even when loaded with the maximum supported memory, it's still not going to be very usable.
I understood that
Sky's HD service was 1080i.
Of course, what you see is dependent on the original quality of the material (up-scaled SD Simpsons will never look good). If you have Sky HD and at least a 1080i TV connected through HDMI, look at some of the HD documentary channels. Unfortunately, too many of these carry up-scaled material much of the time, but you will see some real HD. Some of the BBC sport coverage is also very good (I remember my first Wimbledon in HD, which really showed the difference).
As somebody else pointed out, BlueRay can be full 1080p, as can some of the games consoles.
What we have is a Representative Democracy
You are represented by the person who obtained the majority vote in their (your) constituency.
Not only can you not vote for your MP or MEP at the next election, you also have the ABSOLUTE RIGHT to lobby them to hear and your concerns, and if sufficient interest is expressed to convince them, act on the concerns. Obviously there are limits (don't go stalking your MP, use the surgery process and letters and email), but you should give it a go sometime. You also have the same right to lobby members of the upper house when legislation passes to the House of Lords.
What breaks this is the Party system, that imposes a whip on the way that they vote. In my view, there should be no such thing as the party whip in Parliamentary votes, and MPs should be free to vote in line with what a majority of their constituents want. This would, however, make passing legislation and running a government much more difficult.
Unfortunately, it is necessary to have a representative system for all but the most important issues (where you have a referendum), because the great unwashed masses (and in fact, many of your MPs) are really not interested in the minutia of day-to-day government. When was the last time any of my fellow UK citizens even bothered to watch the BBC Parliament channel, let alone read Hansard or attend parliamentary sessions, and this is often the most interesting bits!
I though nucleosynthesys during the Big-Bang went further. Wikipedia suggests that it went no further than beryllium. I was obviously wrong. OK, just supernovae.
I Am (obviously) Not An Astrophysicist either!
@Runcible - OK, obvious contradiction.
Comes of going back after writing a post and adding to it and clicking submit without re-reading it properly. Yes, heavy elements were pre-solar, but pretty much everything else is some form of solar energy. Still not helpful for the discussion, though.
I like the idea of floating farms, although the energy that falls on the surface of the deep oceans is used by free-floating plankton at the base of the food hierarchy, and also produces the warm water and water vapour that conditions the weather systems. Capture the energy, cool the oceans, and starve the animals in the deep.
As people like Robert Heinlein and others before him said, There Ain't No Such Thing As A Free Lunch!
All energy on Earth is in some way directly or indirectly solar powered. All wind, wave, bio, hydro, ground heat, and fossil fuel comes from the Sun (some may argue that wave power may be driven by tidal forces, but the energy derived is effectively potential energy left over from when the moon was captured, as a result of gravity maintained by the gravity wells in the solar system, the largest of which is the Sun's)
Even nuclear and geothermal power relies on processes long ago that were caused by the Sun (accretion during the formation of the solar system).
You may possibly claim that the heavy fissionable elements are actually left over from the Big-Bang or supernovae, I suppose. If we ever get hydrogen fusion reactors, that would be the first energy source that has nothing to do with the Sun.
Anyway, it's all Entropy.
If you take energy out of a system (or even an eco-system), it is no longer there for what it is currently used for.
The seaweed will currently be passing the energy it gathers up the food hierarchy in one way or another (what eats it either when it is alive or even when it is dead). Removing a large amount of energy by harvesting it is likely to affect filter feeders and sea-born bacteria and krill. Remove these, and you eventually take out things like crabs, prawns and other invertebrates, and then all of the things that prey on those, for example cod and the other large fish (remember, even large fish are very small when they first hatch, and will live on the even smaller things). Also, the seaweed will provide a habitat for animals that may not actually eat the seaweed, and harvesting will damage or destroy this.
Of course, this is no different from any other intensive agriculture (aquaculture?), but when we started cutting down the forests, planting crops and breeding sheep and cows on the land, we did not have environmentalists telling us how much the land would change!
We've still not seen Power7+ announced
so it may be that this is making space for upcoming higher-performance systems within existing products, and doing it early to try to maximise the amount of the existing systems sold before any announcement.
