defense system

its a problem that's relatively easy to solve. Install some UAV denial systems around sensitive installations (airports, nuclear reactors etc)and be done with it. Sure the systems are expensive, but they'll be far cheaper than the consequences and costs of a crashed passenger jet..

Bloke called Rod struck by lightning for second time

Re: re how many are called Rod

isn't the odds of being struck twice just the odd of being struck once times itself, i.e. 1 in 3000 x 1 in 3000 = 1 in 9billion?

That said I haven't done probability maths in years and can't be arsed to google it (it's saturday after all)

European Parliament mulls law on use of blood metal in tech

Please don't do another REACH to us

I've been working in the Electronics industry designing circuits and systems since 2000.. so I've seen the introduction of RoHS, WEEE and worst of all REACH legislation.

I can see the point of the WEEE directive (recycling waste electronics), which negates the need for the some parts of RoHS, namely leaded solders, as its easy to recycle and therefore doesn't contaminate the environment.. and incidentally makes electronics easier (there simply isn't a non-leaded solder anywhere near as good as the traditional tin-lead mix)

However Reach is an utter nightmare for us, as its a vastly larger list of substances, which changes at short notice.. for the average engineer, its simply not practical to check every single component in every design.

But at least with RoHS and to a lesser degree REACH, there are tests you can perform to determine the content of PCBs. However a conflict mineral is identical to a non-conflict mineral.. so this becomes even harder, as even fairphone have found, there's simply no way to be 100% sure.

So then the question is what is the point of a new law that cannot be enforced? how do you prove a company is using conflict minerals in their supply chain for a prosecution? and if you can, how can you prove they did so willingly?

For heavens sake EU.. we don't need any more hurdles to getting products out the door! The problem needs tackling at source, not at the end of a supply chain

On the subject of cooked cheese, grilled or fried halloumi would also fit the post-pub nosh neckfiller category, seeing though its dead easy to make (slice it, bung it in a frying pan with a little olive oil and maybe garlic and herbs, fry on both sides 'till golden), its lovely cheesy and salty.. though the saltiness always makes me want another beer...

Re: An explanation

hmmm I'm thinking of smokey bacon.. will go well with the chili sauce methinks :-) and crispy bacon is best with eggs, gives a nice contrast in texture with the runny eggs.. although rind is optional, can be a bit of a pain in sandwich (you end up pulling half the bacon out with every bite), but you can't beat the taste of crispy rind.. dammit I'm hungry now! luckily there's a cafe 5 minutes walk from the office :-)

having over indulged in curry and beer last night, and still suffering a bit from the cold this seemed to be a stroke of genius.. so off to the kitchen I went in search of what is to all intents and purposes "food porn"

I was fairly faithful to the recipe.. though I agree with earlier posters comments about the insipid flavourless encona so called "chili sauce", so instead I used a good dollop of Mad dog 357 (about a teaspoon full) with a couple of teaspons of nandos garlic peri peri for some extra flavour..

What can I say? it was a warming satisfying gooey mess, necessitating in a hasty shower and change of t-shirt.. and I feel much better already :-) Will definitely make it again.. though I feel the recipe could be improved with the addition of some bacon (anything tastes better with bacon!)

Re: When I finished my STEM there were no jobs

As Ledswinger said, the quality of STEM education seems to have been declining in the UK. In Electronics Engineering, new graduates are often pretty useless when it comes to design work. But the degree at least gives them the basics, so after a couple of years of mentoring and practise they can become useful members of the team. I suspect that's part of the reason graduate wages aren't great.

The other part of it is that too many people can call themselves engineers these days, so yes the respect for engineers has declined. However its definitely possible to get decent wages, particularly in fields that are more difficult and in demand. RF Engineering and DSP are a couple of good examples.

I think the final part of the problem is Engineers themselves.. we're next to useless at negotiation compared to other parts of the company (e.g. sales, marketing etc), so on average our wages are lower, despite the fact engineers can make or break a company just as easily. If you believe the psychiatric studies its probably because most of us are Autistic to varying degrees! in fact if you believe an old 'el reg article, we're cold and dead inside, with no empathy for others.. sounds like most engineers that I know :-)

Too bloody right!!

Tuition fees should be based on their value to the economy and to society.. i.e. if Engineers are in high demand, engineering degrees should be lower cost and/or subsidised. Those that elect to study far less useful subjects like "David Beckham Studies" should be charged more to pay for those subsidies. Agreed this might not cover all the costs, but the gains in productivity and ultimately tax revenue for having more STEM workers available would easily outweigh the additional costs.

I keep seeing articles about Uni-grads working in jobs that have no relation to their degree.. what's the point of that? OK, i can understand that some industries can be difficult to get into, but if a significant proportion of students never get into their subjects then they have wasted their time and money as well as the taxpayers.

UK's CASH POINTS to MISS Windows XP withdrawal date

horsham_sparky
Holmes

That's what you get for going with Microsoft

Windows was never intended as an industrial OS (ATM's would probably qualify as industrial, harsh environment, long service life etc)

There are other OS's out there with better security, support and licensing options, and I don't just mean the various flavours of Linux.

But companies like NCR go for windows because there are lots of Dev's out there with windows experience, and the inbuilt UI cuts down on some of the development time. Plus they can now charge their customers for brand spanking new ATM's rather than just upgrading the old ones.

Its the banks own fault for not specifying a more suitable OS and feature roadmap for these devices.. no sympathy at all.. just annoyance that the cost will be passed on to joe bloggs public yet again.

Re: Perspective

My facts are straight. I don't pay myself a full salary, I take some of it in dividends (like most contractors). I still pay PAYE to keep up my NI contributions. I fully agree, corp tax is paid on profits after expenses (i didn't state that it wasn't)

my point was that the original post was misleading, which I still stand by

Re: Perspective

Touché :-)

Not living/working in London, the ones I know earn considerably less than £500 per day. The additional costs of living in or commuting to London and the more specialist area (banking) probably accounts for the difference.

However I still stand by the fact your post was misleading as you didn't account for most of the costs contractors face. I regularly get told by permies/managers that I'm a rich contractor (I wish), purely because of this kind of misconception, which tends to get annoying after a while

Re: idiot bosses @horsham

Yep, I've heard those justifications before. And then those large companies wonder why their IT/Engineering projects run over-budget, deliver late and don't meet the requirements.

When IT and Engineering resource decisions are made on purely financial reasons, that's when projects go wrong. The sad fact is that as a contractor its rare that I get contracts in well run engineering departments.. almost always they're getting me in at the end of projects, when deadlines are looming because they haven't properly resourced or specified the projects, and are they are into headless-chicken mode of project management.

using contractors in this fashion means that you lose all the learning and experience that they gained during the project.. that means future projects take longer and are a lot more wasteful. Its a false economy.

Unfortunately financial planners rarely understand this and think IT staff/Engineers can be brought in and moved on at a drop of a hat and still keep their effectiveness and productivity.

So your justification whilst being a valid one financially just doesn't work very well in the real world :-(

Re: idiot bosses

My experience is that most bosses in the IT/Engineering sector don't understand the skillset of the people they employ, and therefore are unable to place a value upon it. Those that do understand will rarely bother with contractors but will seek good pay/conditions/opportunities for their permanent staff. However this seems to be the exception rather than the rule these days :-(

Re: Perspective

Why don't you actually talk to some IT contractors and find out how much they're paid? 'cause frankly I seriously doubt there are many earning that level. Most will be between the £300-£400 mark per day, see

http://www.contractoruk.com/market_rates/

As a highly qualified, and in demand Electronics Engineer (there's a shortage of us in the UK), not even I earn as much as £500 a day, nevermind £700 a day!

You also didn't add in corporation tax (20%), PAYE (yes, most contractors DO pay this, myself included). Add in some travel and lodging expenses (a lot of contractors like myself go where the work is, and that means local accomodation during the week and long drives at the weekend). So if they're doing well, they might net between £50k and £70k per year, assuming they work all year around. Take away pension contributions, healthcare, professional indemnity insurance, end of year accounts and tax returns, etc etc etc, then I think you'll find contractors are not the extreme high earners that you make them out to be

Please get your facts straight before posting stuff like that, you only reinforce the misconception that we contractors are earling loads'a'lolly... though we would if we could!! :-)

sounds like Electronics contracting is different to IT contracting, I've never had to drop my rates.. Although I do move around every year or two to ensure I keep getting market rates (companies never voluntarily increase their rates unless they're desperate to keep me) and to make sure I fall foul of IR35

Re: pressure switch

the way you might do it would be using a watchdog on the electronics that powers a normally closed relay which is in series with the pressure switch. i.e. if the watchdog is cleared regularly it powers the relay and keeps it open, thus preventing the pressure switch from firing the rocket.

If the electronics fails to clear the watchdog, or loses power completely, the relay automatically closes (they're spring loaded and need power to hold 'em open), and allows the pressure switch to kick in at the correct altitude.

The caveat being the software needs to be well written to ensure it doesn't arbitrarily keep resetting the watchdog (a common mistake when implementing watchdog monitors)

you could also have a seperate radio system to close the relay to allow the pressure switch to fire the rocket.. all of it is extra complication of course, it just depends if you want to allow the balloon to burst without firing the rocket (for a re-try for example)

Re: "Failsafe" doesn't mean what you think it means.

The accelerator was meant as an example of a system that only "fails safe" if it stops performing a function (i.e. continuing to deliver radiation is an example of a system which does NOT fail safe), whereas the ventilator is the opposite.

You would hope the ventilator alarms and that someone reacts quickly enough to prevent serious harm to the patient, but that situation is definitely not fail safe! Having designed the electronics for a ventilator in a previous job, I can tell you that although the designs do include redundancy for critical systems, the pneumatics is arranged such that even under failure conditions it still provides positive air pressure to the patient. This is an example of a system that continues to provide a function under failure conditions

So perhaps I wasn't clear in last nights semi-drunken post (new batch of homebrew was ready last night mmmm), but in my own mind at least I wasn't confusing redundancy with fail-safe, but hopefully making it clear that fail-safe is a term that can have many meanings depending on what it is applied to :-)

Re: "Failsafe" doesn't mean what you think it means.

you're 100% right and at the same time 100% wrong.. yes that's contradictory, but please allow me to explain!

Firstly my background as self proclaimed expert (or nearest semi-expert in the vicinity), I work in medical electronics and have had formal training in safety engineering and much experience in designing stuff that is "failsafe"

you notice the exclamation marks (in real life I might have been making a funny gesture with two fingers)

you see, failsafe is all a matter of context. a rocket that fails to ignite.. has it failed safe? it depends if you're the bloke that has to approach it afterwards!

likewise, a linear accelerator that generates high energy x-rays.. it fails and continues to deliver radiation? definitely not safe! likewise a ventilator that helps a patient breath.. it fails and stops pumping gas into the patient.. is it safe? again definitely not!.

In this case, what the author means by "safe" is that the rocket is safely away from the balloon.. so if the main launch system fails, it has a failsafe backup that ensure the launch. Remember "safe" has many meanings depending on the context of the project

:-)

Re: dont know much about them but..

oh and p.s. its a mechanical switch.. i.e. its a mechanical mechanism that closes electrical contacts, much like what has already been discussed through various garden-shed arrangements of ice, bluetack, loo-rolls etc, however engineered by professionals (probably with lots of letters after their name, like Msc, Meng, Phd etc) to actually work :-)

Re: dont know much about them but..

I wasn't talking about a sensor (i.e. converts pressure to voltage), but a pressure switch (triggers the switch at a preset pressure level).. link again;

http://www.appeng.co.uk/product/psf101-ultra-sensitive-pressure-switches-with-fixed-set-points-spst-contacts

yes it has 20% tolerance, however on the 14.92mbar unit (approx 29500m), this equates to +/- 3mbar or around +/-1500m roughly. There are two ways around this if you need it better, firstly you set your primary electronic trigger to a level below this (say 27,500m), and make sure your burst altitude is higher than 31,000m

alternatively you can talk nicely to the manufacturer and get them to pre-select a unit with the right pressure trigger point for you :-)
