Something sounds odd. There are plenty of people with months and months of uptime without any sort of corruption. Me included - I got a old B256 with OpenElec that has been running with occasional reboots for a year and it's still fine.
SD card corruption.
The corruption caused (actually increased the frequency) by overclocking was fixed some months ago.
Corruption caused by wearing out the cards might be an issue, SD cards do have limited write cycles, so avoiding excessive writing can increase life considerably. Turn off logging to card. Leaving them for a year might be hitting that sort of issue, in fact I would think it quite likely if you haven't taken precautions to reduce write cycles.
Your particular job would be better served by the compute module by the sound of it.
Nope, max 1GB, and only if a manufacturer decides to make a POP chip that fits, Which won't happen. So 512MB until the next version comes out. I believe Eben Upton has said this will be the final revision with the 2835.
Re: The B got a memory memory in a previous rev @MAge
Actually, the SoC in the Raspi was designed to go in to mobile phones as a media processor (and other stuff). The GPU was specifically designed for H264 decode at 1080p30, encode for camera at the same speed. It has fast 3D and 2D graphics for running games. The ARM itself was added as an bolt on goody.
And the EXACT SAME SOC was used in the Roku2 - which as I am sure you are aware is a media box.
So it's media credentials are actually really quite good. The ARM is a bit weak for real speedy UI stuff, but we use it at home to stream stuff wirelessly from the PVR and NAS, and also use one in a motorhome as a wireless AP so the sprogs can stream stuff to their tablets on the move. Works fine with XBMC.
I do tend to overclock to 900Mhz (simple config change)which does make an appreciable difference.
Re: Birthday present sorted :-)
The PiBow coupe case is pretty damn good. Easy access to the GPIO so add on boards are outside the case...

On the whole
Since the majority of the panel seem to be fairly well educated, even if not in a scientific subject, I would suggest they are all bright enough to make a fairly sane assessment of the situation.
After all, their degrees were a long time in the past, and we all learn a lot in the intervening years. I have a degree in computer science, yet know a fair amount of physics etc. I can also strip an engine and reassemble it WITHOUT ANY BITS LEFT OVER. I certainly wasn't able to do that when I left university.
In short, people can be smart in more than their degree subject as long as they start off smart.

What you have to consider is that when you got on a plane and went to Shanghai, what happened was that you left the UK (I presume), and flew quite a long way to A DIFFERENT COUNTRY.
These 'DIFFERENT COUNTRIES' may have completely different road rules.
Note: Some plane journeys do NOT result in leaving your country. Please refer to the ticket for more information, but a good rule of thumb is that if you need a passport, you have probably changed countries and should therefore not necessary apply the same rules of the road.

Re: Say, Lewis
The F35 would clearly well well ahead, right up to the point it caught fire, crashed and burned.
Microrapter 1 : F35 0.
Launch was 100% succesfull...
All 6 satellites were release to the correct orbit.
The bonus feature, booster return, well, the jury is still out on how well that went. Not yet enough information to know what happened.
Re: It's not a boat.
I agree on the back to the drawing board comment - it's complete bollocks. The author should be completely ashamed of that since its so far from what will happen, especially since the amount of data from SpaceX is simply 'Kaboom;' and 'we need to look at telemetry to see what happened'. How any professional journo who doesn't work the the Fail can equate that to back to the drawing board is beyond me.
Re: Detail for four USB ports controller?
It's pretty much the same chip, but with a 4 port hub. Cannot remember the part number but it's almost the same! The chips are actually pin compatible which is unusual.
Re: Ungrateful trolls
Mr Palmer (shades of NCIS?)
Your continual anti-Pi stance is tedious in the extreme. If you don't like them, don't buy them, but this incessant campaign against what is an educational charity is getting rather loathsome. I really don't know what they have done to you to cause this level of unpleasantness - did one of the Upton's tread on you in a previous incarnation? So as you have stated so many times, there are alternatives if you are willing to pay more and accept lower levels of support. So I suggest you do exactly that, and let the Raspberry Pi foundation do what they can to help with education and continue to sell millions of devices to an generally more than happy populace. The Raspberry is still the cheapest and best supported device out there, not the most powerful as you might expect given the low price, but certainly adequate for its many millions of users. Just accept it for what it is. You'll find the world a much more pleasant place.
Whilst there is nothing at all wrong with the Odroid, on which planet is $65 only a bit more than $35? That's nearly a 100% price hike! Ok for people with spare cash, not so good for people without.
People do need to remember that there is a huge range of SBC's out there, from low to high performance, with equivalent low to high prices. If you want cheap and cheerful, the Pi is great, if you want fast and expensive, there are boards out there for you (Odroid). There really is a spectrum, and you can buy what you need.
Aside from that spectrum of price and performance, look at support, both from the supplier and the community. In my opinion, the Raspberry beats a lot of the more expensive devices hands down. Also, third part add-ons are plentiful for the Raspi (and some other devices).
So, don't just look at the price per MFLOP.
Re: @Daniel Palmer
I'm under no assumptions about you at all.
This new version of the Raspi fixes the problem with hot plugging of USB.
FTDI chips should now work fine. That's the software fix I was talking about. If you are still seeing any problems and are using the very latest firmware and kernel (it appears your version is woefully out of date), please let the engineers know via the forum or via the firmware/kernel github reporting system.
SD cards wear out. Nothing the Foundation can do about that. There are techniques you can use to reduce the amount of accesses to the SD card which helps a lot.
Boo Hoo yourself.
Re: Ungrateful trolls
Expect they were. They were the interface from the ARM to the GPU hardware. Just not the sort of drivers people are used to.
Since you seem so well versed in SoC availability and what the market wants, why not design and build your own competitor?
Or are you one of those people happy to complain because product A doesn't do exactly what you want but not so happy to actually get off their arse and do something about it?
There are already competitors out there trying to compete on price with the Raspi. None of them are doing very well. The BBB sales are terrible, the Banana Pi infringes more trademarks that you can shake a stick at, the Cubie is great but expensive. The rest come under similar categories.
Consider - if there are all these great chips and devices out there, why isn't there a faster better Raspberry Pi competitor out there? It's been TWO YEARS. You would have thought there would be one by now. And yet there isn't one at the same price point, with anywhere near the same level of sales or support.
Maybe, just maybe, it's a little more difficult than you seem to think? Maybe, just maybe, the Raspberry Pi has hit the sweet spot of price vs performance and no-one else can reach it? Even with all those cheap as chips high performance ARM chips out there.
Re: Ungrateful trolls
I get nothing back for my shilling, at all (and I can prove it). And warning you that you are straying on to libellous grounds is not shilling, but simply a warning. You are implying the Foundation are lying about something. That can get YOU in to trouble. Not me.
There will be no fee for that legal advice. I work as a volunteer at this stuff.
As for numerous people calling them out, I think you will find that NOTHING the Foundation has said with regard to those drivers is untruthful. Nothing at all.
So, please STFU with your FUD, and that will mean us shills don't have to keep putting right all your incorrect statements and out of date information.
Your information on the USB is out of date. The huge majority of issues with it have been fixed. There are some corner cases where you might still have problems, but they are rare.
If you are going to continue to slag off the Raspberry Pi, please make sure your facts are correct first.
Re: Physical Size Change
There are already cases available for the new device, costing from bugger all to all of £10.
Not sure that maintaining backwards case compatibility is a good enough reason to cripple the new design.
More RAM and/more speed would have required a new SoC. And that would break a lot of backward compatibility (and wouldn't be a B+ but a C model).
This is an evolution so as not to require too much in the way of change. It basically fixes up most of the problems people had with the original device - lack of USB, connector placement and power supply.
@ JOhn Bailey
Well said sir!
Indeed - the prices are exactly the same, so you are actually getting more for your money. No need for a hub for example, so overall cost is actually lower.
Re: Extra usb ports?
Most of the USB issues are fixed with some rather splendid software effort from a couple of guys at the Foundation - it's rather good work.
However, you are still limited to a total bandwidth as previously. But the extra ports mean you can add keyboard, mouse, USB HW, wireless adapter without a hub, so that's the real benefit.
Oh No! Looks like the cat lovers have got the op deleted. (My first ever deletion - and it's on a cat subject. How odd....good job I never posted that Kickstarter campaign for a statue of Jimmy Saville)
Shame on you all. Please acquire a sense of humour. You'll find the internet a much better place with one.
Er, no point in down voting the comment on the thumb up/down state. You need to downvote the original post for it to be statistically pertinent.

Re: I expect you pay for garden fertiliser.
Nope, have a compost heap. A compost heap that cannot give you Toxoplasmosis.
In other news, is there any way of harvesting energy from all those glass panels? Can you make them with tubes inside so you can run fluid through, then through a heat exchanger? Would take a lot of energy out of the rays before they get inside.
Hmm, going to have to look that up now.

So 0 from 2. Well done.
Motor racing is a NON CONTACT SPORT.
It much too fecking dangerous for it to be anything else. Already we have drivers who grew up with that heap of crap that is BTCC crashing in to each other because they think its OK. It really isn't. The bad example set by BTCC will eventually result in someone getting killed, because of "it was OK in BTCC so I thought it was OK in FFord" syndrome.
This was a Jake comment - it's clearly complete shite, and should be simply ignored.
Have you people learnt NOTHING.
Re: the noise @ledswinger
What a crock of shite Mr Ledswinger.
Please don't bother commenting on something you don't know or care about..
Hold on, this is the Reg isn't it? Not HYS or the Daily Fail? Or, worst of all, YT comments
In order to do a 20 minute race in my race car, I had to install a larger fuel tank. (at about 10mpg)
So 25 minutes in one of these is plenty. The vast majority of races are less than that.

Re: instead of licensing indigineous USA tech from Elon Musk, @tom13
I don't think simultaneous ignition of a lot of engines is a problem. The Russians have been doing it for years, and the Falcon's hold down means they do not launch unless all the engines are up and running.
Multiple engines means you can have failures in flight and still complete missions.
And of course, there are massive economies of scale in making lots of small vs one big engine.
Finally, the Falcon stages need smaller engines for recovery - the sort of big engines talked about here cannot be throttled low enough to be the primary engine on return. Even a single F9 engine need to be deep throttled for the stage recovery, as they are so light by that stage of the flight.
Re: instead of licensing indigineous USA tech from Elon Musk,
Whilst there is some waiting to do before Musk proves his rockets are as capable as this one, I really do think his rate of progress is so fast, that even if this is the right decision now (is it? Lockheed and Boeing do have a very good track record with Delta etc), it won't be right decision in 5 years time.
When they do indeed end up following Musk to Mars.
And yet, when that does happen, no-one will be embarrassed they just spend $20B of taxpayers money on something someone else could have done for $5B. I've never understood that.
Re: Sadly people are idiots
I used to think that, then spoke to a chip designer who put me right. There are definite benefits of 64 bit CPU's over 32 even in today's devices. Although code might get a bit bigger, memory foot print also, (but not by huge amounts), there are clear performance benefits of going to 64 bits.
Although marketing does play a part, it's not all snake oil.
