Bugs In SCADA Software Leave 7,600 Factories Vulnerable

DamonHD Re:Some can some shouldn't (70 comments)

Hmm, I prefer Java over C and assembler because although I can write highly stable and secure code in C/asm, the effort to sustain the required level of paranoia and navel-gazing is for most code better directed elsewhere to visible benefits. I write code that actually has respected security crazies and bank auditors telling me to lighten up a bit, yes really!, but I'm still perfectly capable of making a mistake.

However, I'm inclined to think that whoever wilfully lets code out the door without appropriate bounds checking and incredible scrutiny of all input should face some kind of punishment.

(I dislike C++ because it combines the traps of C/asm with some novel ones of its own, but fools programmers into thinking that they are in a safe programming environment... Yes, I did a lot of C++ design and coding in mission-critical applications too!)

There's a Downing Street in NYC, last time I looked, but it was a sewing materials and/or repair shop IIRC.

3D Printing: Have You Taken the Plunge Yet? Planning To?

DamonHD Re:Yes (251 comments)

Compared to identical prints on other printers that I've seen I'd rate it "medium".

After some delay getting it (I think Maplin was overwhelmed by interest) and some teething issues (Maplin just shoved the assembled unit into a cardboard box without proper packing so it arrived quite bent out of shape in places) and allowing for one continuing defect that I've worked around, I'd say it's a good little workhorse for the money especially considering that it's still pretty bleeding edge tech.

3D Printing: Have You Taken the Plunge Yet? Planning To?

DamonHD Re:3D printing (251 comments)

You can't throw nice 2D printers around either and expect them not to suffer.

The process is not as painful as you think.

Myself and one other on the OpenTRV (opentrv.org.uk) project work to get OpenSCAD files and fromt hat we produce STL and many of us (maybe just short of 10) print from that same STL on lots of different printers with different setups without significant difficulty.

Yes, my 3D printer is a bit 'beta'y and slow, but it does work, and is now reliable and easy to use.

3D Printing: Have You Taken the Plunge Yet? Planning To?

DamonHD Yes (251 comments)

I have the Velleman K8200 and for the OpenTRV project (opentrv.org.uk) that I'm working on we've been able to print the enclosures and well as designing the hardware (and making and stuffing PCBs) and the software in the same distributed fashion, and easily outsource to third parties for larger runs (hello Thames Valley Rep Rap User Group TVRRUG; thank you again).

It's been fun and helped us to control more aspects of the product while still in prototype phase.

U.S. Teenagers Are Driving Much Less: 4 Theories About Why

DamonHD Re:It's not a bad thing. (635 comments)

To be clear; I'm entirely prepared to believe that the first 1000 hours of anyone's driving are their worst.

But I suggest that the first 1000 hours of an 18 year old's driving are likely much worse (from a safety/accident point of view) than the the first 1000 hours of a 40 year old's driving, on average.

For example, I know which I'd be more likely to trust with other complex and risky activities that don't require particular muscle strength or speed, but where responsibility and general life experience help, eg including running a business or a government office!

U.S. Teenagers Are Driving Much Less: 4 Theories About Why

DamonHD Re:Well Duh. (635 comments)

Hi

I think that's complete nonsense (straw man arguments) and a counsel of despair, and/or maybe an excuse never to do bother anything right yourself until everyone around you is perfect. And I don't imagine that you are completely selfish like that in all your other actions.

And, guess what, altruism and good behaviour in general doesn't have to be absolutely simultaneous to work.

U.S. Teenagers Are Driving Much Less: 4 Theories About Why

DamonHD Re:It's not a bad thing. (635 comments)

[citation required]

Well, except that I expect most 40 year olds to be a little better at judging/taking risks, and somewhat less driven by roller-coaster hormones and emotions.

Thus those 1000 hours should be safer for all concerned.

However, I'm quite happy to be shown to be wrong if you've got the numbers to prove it.

(I also am driving less in part by making sure that I'm in a position to use public transport and control my hours, but I'm in the UK and have never owner a car, though I've driven here and in the US and elsewhere in the EU.)

U.S. Teenagers Are Driving Much Less: 4 Theories About Why

DamonHD Re:Well Duh. (635 comments)

Quite the reverse: shows just how much individuals can make a difference by, for example, avoiding flying (or at least travelling long distances) for no sufficiently good reason.

I haven't flown in years and and don't feel I'm missing much. We take family holidays fairly close to home by train though be may now ... ahem ... push the boat out and take a decent ferry ride this year to give the kids a taste of another country. We're still managing to be close to carbon-negative at home for primary (6t less CO2 per year than a few years ago) and I'm not going to waste those savings on a mindless travel binge.

I can only tell you that some pretty smart people are running that show and I did my computing MSc with the CEO, and he certainly knows his stuff.

It's not a guarantee of course, IMHO it improves the odds.

There are various virtual cards available on-line (I was CTO of one issuer) where you can create a new card with a new number with exactly the limit required for each transaction, eg if you don't trust the retailer fully.

How One Man Fought His ISP's Bad Behavior and Won

DamonHD Re: Use public DNS (181 comments)

It must be lovely to be without error like you, other than hiding behind AC to cast insults of course.

I *do* know what I'm doing, generally, and have the track record to show it, but the threat landscape has changed quite a lot recently. And because I don't assume myself to be perfect I was alive to the issue when it showed up, and responded quickly, which seems like the rational and responsible thing to do for us normal non-perfect people.

How One Man Fought His ISP's Bad Behavior and Won

DamonHD Re: Use public DNS (181 comments)

Really depends what you mean by 'private'.

I've been running my own (mine/company) Internet-facing DNS almost since there was live IP in the UK and I got caught out by this.

And I still see people regularly *trying* to use my DNS for amplification, ie probing, or at least laundering their attacks, but give up, after I made the appropriate fixes.

And I'm not alone. (See recent item on The Register for example.)

Reducing UK housing CO2 emissions by 80% by 2050

DamonHD DamonHD writes  |  more than 6 years ago

DamonHD writes "The Low-carbon Strategy from the Environmental Change Institute http://www.eci.ox.ac.uk/ at Oxford University identifies the policies needed to deliver an 80% cut in carbon emissions from UK homes by 2050. These cuts are achievable but will require a quantum leap in commitment from Government and a radical new approach.

The policies have been designed not only to dramatically reduce carbon emissions, but also to be delivered equitably. The poorest households will be prioritised for assistance and fuel poverty will be wiped out. The scientific consensus is that for the UK to play its part in helping the world avoid a rise of more than 2C, we must reduce our carbon emissions by 80 per cent by 2050. The household sector represents 27% of our total emissions and achieving deep cuts here is an imperative.

The low-carbon revolution starts at home.



Their previous work at http://www.40percent.org.uk/ from two years ago is also very interesting and thorough.

I'm amazed to find that with some simple measures at my home/office my family seems to have hit something like the 2014 targets already..."

Dead Milk Tanker for Zero-Carbon London Home

DamonHD DamonHD writes  |  more than 6 years ago

DamonHD writes "Is it possible for a small urban (London, UK) home to be powered entirely by locally-collected Renewable Energy, both for electricity and for heating?

An important issue is that there is only ~20% of the solar energy per day in winter compared to summer, so one way to make the whole project more likely to work is to store energy from the summertime to the winter.

This article looks at storing enough heat energy out of the ~26GJ used by one house per year for water and space heating to last the winter, 'charged' by solar thermal panels year-round.

And yes somewhere between 1 and 3 dead water-filled milk tankers buried in the the ground could hold the required energy!"
