"Sure it's security through obscurity, but obscurity worked for Linux for years."

Level 5 driverless cars by 2021 can be done, say Brit industry folk

"The sooner we get rid of the knobheads the better."

Whilst we can probably agree on that it's clear that with the statistic quoted about 1 fatality in 1e8 miles it's going to take (as mentioned) a lot of testing before a) people, b) insurance companies are persuaded and then people will be put-off by the likely extra cost and (presumably) the maintenance ( sensors/computers etc. will need checking, upgrading and certifying ) regularly.

Re: Forth

"That would make it a fine language to compile into".

Indeed it would but the benefit to me was I needed no other support other than an ability to lay-out & etch PCBs and a self-written serial terminal program. This was a long time ago (certainly pre-1985) when hardware was expensive and I was a relatively poor chemist. Still have the hardware somewhere ( in an enormous case).

My reason was that you could fit the whole system into ~6KBytes (6809) including (simple) disk i/o. With that you could control a whole heap of hardware without needing assembly all the time (and an in-line assembler if you did need it)

Re: Too Late....

"can access your PC remotely without your knowledge."

Someone called yesterday from "MS security" and tried to access my computer ( with my knowledge but not my cooperation I might add)

So I did the usual :

"Oh, it's switched off"

"It takes a long time to boot" {fill & switch on kettle}

"Are you still there ?"

"Yes it does take a time", {make drink}

"Silly me it's off at the switch"

"No, nearly there now"

"OK which key do you want me to press?"

""The Windows key - which one is that ?"

" No, can't see that - where is it on the keyboard ?"

"Wait a minute I can't find my glasses "

"3rd in from bottom left ?"

"No still can't see it - the only key there has a penguin on it "{ which it does- came already installed as well}

"No, it's not a real penguin - what would I be doing with a live, or indeed stuffed penguin on my keyboard - the cat's bad enough" { quite a lot of swearing, and suggestions what I could do with it}..............

If I've got time I'll go off to answer the door for a while as well...

Linux 4.14 'getting very core new functionality' says Linus Torvalds

Re: @Geoffrey W

" I started writing programs back in the 8-bit days"

Me too. ( SC/MP, 6502, 6809, 68000) . Tried Linux back in ~~1995 and have been using it ever since.

Try a USB/DVD as suggested or install into Virtualbox if you have a capable enough machine. Another cheap route is to buy a Rasp. Pi - once configured (using a monitor/TV, keyboard and mouse for convenience ) you can run it just from a laptop/desktop with a USB cable to provide power and an ethernet cable to provide connectivity to run a shell, virtual desktop or whatever.

Re: Windows vs Linux ... really?

"And where do we get from this announcement? Lame complaints that Mint GUIs do not appear to provide equivalent functionality to Windows firewall management. Really?"

It's noteworthy that many Linux articles have ACs ( or people joining the Register the same day) asking somewhat naive questions designed, it seems, to highlight the (apparent) deficiencies of Linux v. Windows. Usually they slink away when challenged !

Too many ACs by far BTW. I can understand it when they might be compromised by their answer/knowledge etc. but mostly just hiding to make untrue or snarky remarks.

Indian call centre scammers are targeting BT customers

"I got a call from my ISP (Plusnet - BT owned) the other day,"

Well I know what you mean, but I was called by them a year or so ago and offered a much reduced charge for what I was getting (unlimited download, fixed IP, domain name and web-space) . I'm very cautious about this kind of call but as they didn't want any details I went ahead and it was all genuine. Just wish genuine companies would think about how they appear to people they are (cold) calling.

Dangle a DVR online and it'll be cracked in two minutes

Re: DVR?

@Cynic

Thanks but I wasn't looking for advice for my experiments - I'm happy that I can do it . I may have expressed myself badly.

To put some code to it :

Remote pi : ssh -fN -R 7000:localhost:22 -p xxxxx user@home_ip_add

(where xxxxx is the port forward by the local router)

Local : ssh user@localhost -p 7000

will give a login prompt on Remote pi

Re: DVR?

"which record locally but as far as I can tell are not visible (at least to Shields Up) to the Internet. They have LAN connections "

I'm a little concerned that a untrusted device with internet access could set-up a reverse tunnel from a remote machine.

I've been playing around with this as I'd like to routinely access a remote Pi of mine in Switzerland from home but have no control of the (remote) network it's attached to to allow crossing the firewall.

It all seems perfectly feasible and I can easily access my home network using ssh from Switzerland and then (remotely) connect back from home to login to the Swiss remote.

Can anyone comment on this type of mechanism in relation to giving internet access to untrusted devices?

Yes ( for years ) and I NEVER use it - what's the point ? If I drive another car I still have to know how to park it. Where I normally park on our drive it can't cope anyway.

I point out that plants need many things, oxygen being one. Although they generate oxygen in sunlight during the dark they actively require oxygen. All plant culture will have to be indoors for many reasons.

Re: What about Oxygen?

I'm not saying the chemistry is wrong it's not. I'm questioning the overall efficiency when the supply of energy is going to be limited. Given it will have to be solar or nuclear to run this lot I question how much kit they'll need. The Sabatier reaction, to produce the methane itself is exothermic once initiated but extracting or concentrating the necessary oxygen and then liquifying it will require a lot of energy.

For example to produce 1kg of hydrogen gas by electrolysis will require ~~ 60kW.hrs in the process producing 8kg of oxygen. To liquify the oxygen (for storage and engine use) needs ~~ 5kW.hrs for the 8kg.

I note some of the NASA papers don't actually mention the energy requirements

Re: What about Oxygen?

"the production of fuel from simulant Martian atmosphere has already been tested"

I've no problem with the possibility of obtaining fuel ( from CO2) from the atmosphere it's the extraction of oxygen from a very dilute mix of other gases that I suggest will be a very energy intensive process. Probably better to produce hydrogen & oxygen from any available water even though that will also be very energy consuming esp. to produce/store liquid oxygen

"- Sufficient, even in the atmosphere, to get things going on Mars,"

There are only trace amounts in the atmosphere. ( it's about 0.1% of an atmosphere that is already very low pressure (~0.6% cf. earth )) It would need to be generated from water or some other source.

"Passengers on the train don't need to train as a train driver in order to catch the train."

You miss the point. Any group of people using a particular technology need some in-depth knowledge to use it safely. I did, by the way, include driving a car which is a near ubiquitous 'skill' which in most places requires examination.

I don't expect the average user to be a security expert just to have an awareness of the basics od on-line safety. You certainly can't expect the technology to cope with all the diversity of attacks from the sophisticated to the banal.

On the other hand if you want to do something more unusual, but still reasonable, like give yourself access to your home network from outside then you do need to understand what you're doing or take advice.

The point is that it is necessary however much you'd like it not to be. I don't think I'd be too happy with an unskilled bus/car/train driver.

And that's before we take into account simple scamming/phishing by computer/phone or mail. We can't design/legislate for a risk-free world - people have to have an awareness of risk whatever activity is undertaken.
