Not sure that this is a real problem, I read it as a statement that currently these devices are not permitted by the US FAA. In other words, new regulations and controls would have to be put in place to regulate and control what is in reality a new flying protocol - autonomous, out of line of site of operator, satellite (or otherwise) navigated devices.

ARRRRR. Half world's techies are software PIRATES – survey

A lot of licensing is still done on trust, particularly in the the larger corporate environments (or where I currently work at a top University). Server licences particularly so, as the user / access licences are worded so vaguely or inclusively that for example a data access middle tier would only require a single licence to connect to the database tier however could be serving hundreds of distinct users connecting to it. It can be argued that requiring the number of user licences for the number of end users is fair, but where does stop? Are viewers of reports included? How about live (cached) reports hosted on an intranet? To add to it, you then need a few maintenance, service or operational accounts as well.

Re: > there are useful things to be had from it all.

With the fridge I was trying to demonstrate that while it may currently be a relatively basic example, there are potentially useful things that can be done. Even for these examples I would agree that it's a toss up whether or not it's worth the effort, but that's something else and once these things become more commodity then the effort is diluted sufficiently and what was previously a gimmick or "nice to have" feature, becomes standard. The same arguments about "it's not worth the effort" were probably thrown at a lot of the technology that we currently use, take for granted, and would be inconvenienced without. And we'll have forgotten the stuff that really wasn't worth the effort at the time.

An IP stack may be rather complicated but like most technology these things are built on a stack of previous modules incorporating standards, knowledge and experience. Even a serial interface isn't particularly simple if you have to build one from scratch from the physical layer up (and you wouldn't believe the mistakes that I've come across when people have tried), however modern IC systems can handle most of the annoyances and details for you. So while an IP stack is rather complicated it's becoming an established module that is just another tool that a higher level layer can use.

The only question is how your suggested enhancements will benefit from Internet connectivity.

I don't consider that the "Internet of Things" is specifically about giving everything possible an Internet connection - it's about connecting devices that were previously or are currently not connected to anything else, more local or personal area networks. Typically IoT has evolved as a marketing term / buzzword from Machine to Machine (M2M) communications, which doesn't sound particularly inviting but we've been doing this at various levels for years. What it boils down to is that IoT is little more than the miniaturisation (and feature stripping and simplification) of much larger and more unwieldy systems down to the level where they can become commodity / consumer items. There will be a lot of pointless ideas that fail, it won't be anywhere near as big and pervasive as the habitual "industry" tech-predictors predict, but it will become more and more pervasive once people find useful things to do with it and devices like Arduino, Raspberry Pi and similar are the start and allow a lot of interesting, sometimes useful, experimentation.

On the fridge example above, while I agree that in general the simpler something is the better, it doesn't mean that things can't be enhanced. For example, the temperature of the fridge could be monitored allowing an alert to be generated if the temperature goes outside defined limits for a period of time, for example when a toddler (or drunken / sleepy adult) merrily raids the fridge and leaves the door open, the cooling unit fails or some other miscellaneous and annoying problem that'll ruin your morning when you find the milk is off. Hell, just the opening of the fridge between certain hours could raise an alarm if you really want to stop midnight fridge raids. A little more sophisticated could be humidity sensors, where if something leaks a similar alarm could be raised. These are just a couple of simple enhancements to a basic fridge, nothing complicated, nothing that can't be easily implemented right now.

Much of the IoT press is just marketing fluff and noise, but there are useful things to be had from it all.

Hackers steal trade secrets from major US hedge firm

Right. So a "trader" in a virtual market that performs promisory non-transactional trades in this trust-based virtual market as quickly possible while making money from others that do the same claims to have lost some unverifiable virtual money because they weren't making these phantom transactions as quickly as they expected.

Maybe I'm just too cynical but I've yet to find somebody who can genuinely explain just where the money (and value) is generated from these high speed non-transactional, trust based, non-interactive transactions on finite resources comes from.

Russian gov to dump x86, bake own 64-bit ARM chips - reports

Nick Ryan

Re: CPU the only risk?

Exactly, the CPU itself is very unlikely to have backdoors or anything specific in it. Exploits or backdoors are going to be be in the supporting services that surround the CPU, the support chipset: the OS and the OS's device drivers.

By its basic nature, the OS that runs a system requires full access to the CPU, including all operation levels and all metrics and support. There is no point in a "super-duper-secret-access-mode" function in a CPU, this level of access can be performed using normal operations. Access to more privileged operation levels in a CPU is managed by the OS.

The support chipset, on the other hand, will have direct memory access to the entire system outside of the scope of the OS, will be able to send and receive network packets without the OS ever knowing that anything is amiss - this kind of communication will be undetectable inside the system itself, however observable outside through packet monitoring.

Device drivers also tend to have enhanced access to the system, including DMA access and direct access to hardware. At this level they are more readily monitored and the source code can be decompiled and assessed for potentially unwanted behaviour. Depending on how well written the driver code is, the OS is likely to be unaware of unwanted behaviour in the driver, these are trusted components.

The OS itself can easily have backdoors and access code in it. This is more readily detectable as the executable code can be decompiled and assessed for potentially unwanted behaviour, however if written well it should be relatively easy to mask as the OS provides this functionality.

The applications on top of the OS are even more likely to have back doors, access code or just exploitable through programming defects.

In the end the most likely source of leaks is the bag'o'flesh in front of the device. Many will happily sell their passwords for chocolates, use easily guessable passwords or just email or print and lose important information.

British boffin tells Obama's science advisor: You're wrong on climate change

Nick Ryan

Global Warming?

[Sigh] Whoever initially used the phrase Global Warming and prominent public figures who repeat this do a lot of damage to the environmental cause.

The considered term is Climate Change. This is where humans are proven to be polluting the environment and through this there is proven disruption to environmental processes, both local and wider. The exact impact of the disruption to these environmental processes is the main contentious issue: some of these are relatively trivial or have a narrow impact, some while having been disrupted are replaced by other process and some of them are more immediately obvious when disrupted such as the hole in the ozone layer. The difficulty is that there are a huge number of of environmental processes, many of which are interlinked somehow, many are hidden or obscured by others and this makes it incredibly difficult to make predictions of what may happen when one or more fails or is disrupted. Therefore the considered acknowledgement is that while we are proven to be damaging the environment, we don't know exactly what will happen but there will be changes and if we don't stop damaging the environment then the predictability and potential severity of these is statistically likely to be more serious.

It is not impossible that the processes could be disrupted in a manner that could lead to Global Cooling, not Hollywood action-movie style, but it could be as disruptive as Global Warming because it would affect precipitation which would have a catastrophic effect on food crops and the distribution of fresh water.

Re: IT and conferencing

My solution to the presentation problem was to fit a dedicated PC, configured and locked down to the resolution of the projector. Audio went through dedicated speakers, all connectors were screwed in place.

Users could either access their presentation across the network or plug in a USB stick, which is usually daft when they've saved the presentation to a network location, and with non-embedded embedded content always causes fun and games.

I still had some users busily unscrewing everything in order to present a high resolution (aka stupidly large amounts of small text) presentation using a low resolution laptop. They could have configured a secondary display with the correct resolution, or even aspect ratio, but then they wouldn't have been able to see the presentation on the small screen at the same time. Staring at which defeated the entire concept behind delivering a presentation in the first place, which is to present, not to sit there mumbling at a laptop keyboard. To make it worse, I even had a dedicated external connector which users who couldn't understand that they could use a dedicated PC for the task, or were external visitors, could use... but this didn't stop the attempted disassembly of the main system at times.

All this and there's still the point that's most often forgotten: PowerPoint is not a presentation; PowerPoint is merely a tool that allows you to enhance a presentation. [but frequently used to kill one]

I "dodged" that one as well... specifically the cybernetics course at Reading. In the end I avoided AI as much as I could because I quickly considered that none of what was being taught as AI was in fact AI: at best it was Logical Reasoning.

As for Professor Warwick, I consider that he's a very good promoter of the subject, rather over-enthusiastic at times, and he does, in his own way, raise the profile of a lot of interesting problems that could do with being raised - for example the boundaries between human and machine. Eccentric, out-spoken, often technically wrong but largely harmless.

It would be interesting if after all this time he could be persuaded to directly speak with El Reg...

Re: AI is harder than Turing expected

Intriguing read about the "Halting Problem". But it goes to justify why my loosely held general belief that mathematicians should stay clear of programming still runs true.

I've had countless arguments with mathematicians pretending to be programmers... from those that claimed that "5g" languages would make programmers obsolete to those that can't grasp that while small parts of a typical application can be represented in a mathematical manner, it quickly becomes pointless trying to apply such an unsuitable technique to wider applications or algorithms. While it is of course possible, the dataset rapidly becomes a ludicrous set of multi-dimensional possibilities and while the analysis can be streamlined the sheer processing power requirements to model and validate the entire thing renders any attempt pointless. In the end the algorithm effectively degenerates into a simulation. In many ways this is similar to computer chess.

Re: AI is harder than Turing expected

That's the problem with, in this case, a historical lack of understanding. The brain isn't a binary device and while any individual component doesn't run especially fast, they do run in parallel. The concept of a machine fooling a human in a blind test is still a clever device, even if the understanding and predictions were out.

This kind of historical take on something is often quite interesting, for example Asimov's robots could not speak but could understand. It was later advances in technology that lead to the "artificial voicebox" in his books. From a biological point of view it was correct - babies and toddlers can understand much more than they can speak, however from a technology point of view it's reversed as speech synthesis is simple compared to contextual comprehension.

Yes and no. Hence messy. For example, online file streams do not contain metadata.

We present to you: 840 fine, upstanding young disks stuffed into a rack cabinet – DDN

Nick Ryan
Silver badge

The vertical deployment of the drives looks sensible from the purely spatial point of view as it means all the non-drive space (power, data, cables and support) is put into one plane which should optimise the use of space. Vertical stacking would remove the need for cables in the same way that commercial removable external HDD units work (if you're in the business of swapping out HDDs, these kind of exposed external HDD "caddies" are invaluable).

I can't see any details from the picture, but if I were designing this I would combine the cooling and support elements into one form, a thin metal (e.g. thermally conductive) caddy that ensures that the drive sits true on the connectors and doesn't topple or otherwise shear or twist the connectors. It would effectively make the caddy a part of a monster heat pipe.

They will be a bugger to deal with though, particularly when you need to swap a drive in the top unit at the top of a 42U rack. Servers are annoying enough, any although these probably don't have a lid case on top to content with, the drives would have to be carefully removed to not interfere with the operation of adjacent drives.

EDIT: Just googled the SS88460 user guide and aside from the unit looking different to the datasheet model and the image here on El Reg, it has slots for pairs of drives and enclosed caddies for each HDD.
