Re: Can't Win!
"If they don't fix it people complain and when they do it's still Windows."
Here's an idea...
Why don't they record what caused these holes, then train their developers to not make the holes in the first place by a)Fixing the libraries they use (if that's the problem) or b)Fixing the developers.
Because then they'd only pay them once to write the code and could work on the next version in peace.
So heavy to carry and not very good if you're a touch typist
Much like every other laptop then.
Has to be said.
WTF is "Alice Corp"?
Anyone heard of them actually doing stuff?
Note if you wanted to deployed an aircraft in the atmosphere of Mars this is the tech you need
And AFAIK this is the first time that's been done.
Sea water x submerged (IE big pressure difference) x complex mechanical unfolding --> Big f**king problem.
Thumbs up for solving it.
BTW This being a US design the drone will probably have sat commes back to the US or to an orbiting aircraft over the border from the target.
Talking to a submerged submarine is difficult.
IIRC this is an old episode of "Dragnet"
Sadly that did not end well for the thieves either.
The Programmers Apprentice reborn....
So this automated thingy found 1/3 of the bugs in Windows 7 eh?
Now does that mean a)Humans found the other 2/3 or b) it is project that 2/3 of all bugs are not yet found?
I think it's a, but I cannot actually prove it's a).
What people will do to save investing in proper programmer training.
And for those who remember "Get Smart".....
It's also (sort of) the emblem of C.H.A.O.S.
Current speculation is that this flight is in fact a radar reconnaissance satellite (eco friendly version. No on board nuclear reactor as the Soviets like to use).
As it's an active sat it can look through smoke, cloud etc and does not need sunlight, hence the "nothing is beyond our reach." It may have passive modes as well, picking up mm microwave emissions (this on the borderline with very long wavelength IR).
And this is the logo
Actually it looks like an octopus with a bit of attitude as well.
If it could speak you can picture it saying "What?"
To put that in perspective.
The Earth to Sun distance is commonly called 1 Astronomical Unit.
Mars is 1.52AU (roughly)., Neptune (last giant outer planet) 30.1AU. Pluto (OK no longer officially a planet) 39.3AU. And the transit time to Pluto is measured in decades.. And so far no human has traveled more than 1/372 of an AU.
So 650AU is big
Re: @@Phil Dude
"The eye is part of the brain, hence , growing one is quite a challenge..!! In mice where genomic plasticity has been engineered it is possible to mutate all sorts of cells, but with eyes we can knock them out (induce blindness ) , change their proteins (for sight problems), but the actually structure is quite subtle and dynamic."
True. However I think the picture is changing.
Historically DNA has been viewed (quite literally) like a paper tape.
But with the discovery that some of those codes control what's being read rather than are being read directly you're now looking at a Turing machine.
That changes everything.

Re: I'm reminded of a story about the tunnels of Viet Nam...
"That third group then must've been fortunate to not have their perimeter undermined because ONE tunnel snaking PAST their perimeter would've ruined their effort: not only providing an escape path for those underground but also creating a potential ambush point for anyone who dared to go down: possibly creating a line breach for a combined over/underground assault."
That's why you have to establish a tight perimeter first, otherwise it does not work.
In the same you have to make sure you've got all the C&C servers when you hit them.
"There's absolutely no reason for this company to be funded by the taxpayer. This sort of thing should be a core competency and if you aren't doing it in house then you've got no business doing it."
Not at all.
Bankrolling the startup of private businesses set up by former govt insiders with on-the-nod contract procurement is the American way.
I'd cite Ramo Woolwrich Corp, (who became TRW), and various Silicon valley companies who got signals intelligence contracts.
Re: I sense a J2-x fanbois in the audience.
"As much of a sci-tech space nerd as I think I am sometimes, I snese you're vastly over-estimating the audience's tribalism where competing rocket engines are concerned..."
I don't think so.
You have no idea how these NASA fanbois can get.
I snese a J2-x fanbois in the audience.
BE3. Completely new LO2/LH2 gas generator engine built from scratch by newly assembled team.
The current NASA J-2X project is
Combustion chamber. Scaled down from RS68
Gas generator. Scaled down from RS68
Injectors. From original J2 design.
Nozzle extension. From RL10.
Why do it this way you ask? Simple the RS68 cannot be "man rated" according to NASA so new super duper man rated engine needed for SLS upper stage.
Apparently using the J2 injectors makes the new J-2 "man rated."
Hint. If the RS68 were man rated one of the reasons for needing SLS goes away as you you can launch the crew and MPCV on a Delta IV.
"I wonder if RBS's issues with IT are down to the multitude of other banks it gobbled up, presumably each with their own special flavour of software?"
Given bank mergers have been (partly) cancelled because they couldn't get the IT systems to mesh (and give that "synergy" management con-sultants like to talk about) I'd say that could be a factor.
And those integration issues can take years to resolve....
Re: @Don Jefe @John Smith 19
Sadly, not one of your better efforts.
I'm not sure why I got a downvote though.
I'm reminded of a story about the tunnels of Viet Nam...
The VC and NVA were prodigious tunnelers. IIRC in 2 regions the US formed "Tunnel rat" units to chase them down the (small) holes and help destroy them.
They never eradicated the threat.
In the 3rd area they used all the troops to form a perimeter then set up a skirmish line doing a fingertip search of the ground not only for trap doors but also breathing hole. The marked every point.
Then they blew the whole lot up in one go.
AFAIK they did not have any further problems.
IOW you have to be very coordinated to eliminate a bot net completely.
But the infosec people can work together as a team in ways the (illegal) malware writers cannot.

"See also "The Moon is a Harsh Mistress" which detailed throwing rocks from top of gravity well way before your reference."
You might include CJ Cyrn's "Downbelow Station" novels and the company that controls what the miners get, and what they pay for it.

"SpaceX is launching another comsat later this month and expects to be launching one Falcon 9 a month by the end of 2014. "
Well certainly hope to be launching that many.(and I wish them well).
But IIRC they were looking at about six non NASA F9 launches this year.
I don't think they are going to fit the remaining 5 in by Dec 31, do you?
Yes I do expect them to close that launch reliability record quite fast. How fast is another matter.
"I'm not sure that he could. Apart from the fact that India and China want to build their domestic capabilities, there are problems with trying to sell services to China (India I'm not sure). A certain senator would have a fit if he even read your comment."
I think you have it backward.
The trouble is launching US satellites on chinese LV's.
The OP is talking about launching Chinese and Indian satellites on F9.
They ship it to the US. Spacex launch and F9 is only "exported" to orbit.
That is a very different prospect.
" and crashed cics."
CICS is core IBM system software. It sounds very hard to believe a single rogue app can take down the whole subsystem.
The application definitely. An instance on a processor, maybe. But everything?
LO2/LH2 is *very* challenging.
This is an impressive feat by BO. Thumbs up.
However if they are planning to do SSTO on 1 engine it will have to throttle down much farther as the structure will have to be much lighter to make orbit, say around 5%.
People might like to note this is (AFAIK) a completely new engine, in comparison with NASA's J-2X. They might also like to note the schedule it's taken to get to here.
A potentially very interesting...
multi mode trigger for any kind of booby trap.
The configuration protocol sounds like one that any mobile could generate, which is reasonable.
But that business with a server. WTF?
"That's not just a modern thing... apparently the Victorian art critic John Ruskin fled from the bedroom on his wedding night, because the study of ancient Greek statues had not prepared him for female pubic hair. It is arguable that maybe a little bit of porn (with real women and pubic hair depicted) might have been a good thing for his matrimonial relations, in the spirit of 'all things in moderation'."
You mean she "Un bushed" him?
I'm already walking.
Was it Dominic Oconnor who said "Banks are IT companies with banking license" ?
Yes I think it was.
UK clearing bank software is big.
Historically the previous job of the IBM team that built the real time version of OS/360 for the Apollo programme (and its apps software) was writing software for UK high street banks. IIRC that's where they got their change management lessons from as well.
Banks (much like the civil service) don't want to re-write software because it a)May introduce new bugs in perfectly working software (or break workarounds to the existing bugs) and b)Gives them no benefits.
They "acrete" new systems around it to deliver new funtionality. Historically Unix (lot of RS6000 and Sun), then Windows server, now probably Linux.
Multiple hardware platforms x Multiple applications x Multiple languages --> Opportunity for massive clusterf**k.
BTW there used to be a bank-in-a-box packaged for the AS400/iSeries than could pretty much handle all banking needs for foreign banks in the UK, but I'm not sure what it's counter support was like. If it was OK then a new UK bank could be money + iSeries + banking license + office + staff.
"RBS ... Is that not the bank that is deliberately bankrupting its own customers and buying their assets on the cheap from the receivers?
Oh Yes, it is:"
This is more ironic than you probably realize.
Someone did a study on bank ordered bankruptcy in the UK and found a)Banks ordered solvency reports from accountants b)Most reports called for receivership. c)Most receiverships were handled by the accountants who wrote the original report. d) However one bank tendered the receivership work if the accountant said the company was insolvent. That bank had a much lower level of companies in receivership.
That bank was the RBS, pre Fred the shred.
"The Co-Op bank was formed in 1872, and became a 'proper' clearing bank in 1975 - so it's not a new entity."
Except as fo 2013 it's now 70% owned by a bunch of US Hedge Funds and assorted "High net work" individuals.
Not really a "co-operative" any more, is it?
"I don't know if there ever was a time when customer choice actually did have any sway over business practices, but in today's global economy and uniformly lowest-possible-cost maximum-screw-factor service there's exactly f***all anyone and everyone gets to punish / reward / change. There's nowhere to go but from the frying pan into the fire, and the players, safe and secure in that knowledge, ROFL at any customer indignation.."
And as long as people believe they can make no difference they never will The 35% of utility customers who do switch have made a difference. Look at UK gas & electricity suppliers versus water companies who litteraly don't give a s**t.
In the UK there is a magazine called "Money Facts." It lists all bank accounts, credit card, mortgage, loan and other financial providers in the UK, and their interest rates and qualifying requirements.
Yes a lot of them are very similar, but some are not, and the differences can be staggering.
The system only has a chance of working if customers reward the good and punish the bad.
If you live in the UK that means you.

Not in a good way.
Re: How about a little perspective here?
"You got your bird away after a few delays - better safe than sorry - and Falcon 9 has added another string to its bow by putting up a bird destined for GEO. SpaceX continues to undercut the market - who else does launches for less than 60 million? - and, if they can ramp up production then they can really dominate the market in the future - sell those ULA shares now, folks, while they're still worth something."
Err. ULA are too expensive for anyone who is not the US govt to afford them.
Their big selling point is the long list of successful launches. IIRC their most successful size has 40+ perfect launches, the total for either Delta IV or Atlas V is 60+ each.
"Next Generation? SLS is a very, very, very expensive rocket "
"that has a high risk of being cancelled before its first flight and,"
You wish. Actually I wish too :( but that boat has sailed. The epic loads of pork being cooked up demand a launch, never mind that report after report states the Legislature have not given out adequate fund to do the job quickly and safely.
" after SpaceX gets their (first stage only) reusable F9 flying & of course their Falcon Heavy going uphill too, is bound to be cancelled after the the first or second flight."
I think Spacex will get FR and FH flying but that does not lead to SLS cancellation. Not going to happen in this universe. There is logic and there is politics. SLS is not driven by logic.
20 000 Kg is 28% of the baseline SLS and NASA are saying that version will likely run 105 tonnes.
Likewise FH is a tad over 50% of the 105mt base line and a tad over 40% of the full 130mt SLS.
However a) Even 5 F9 launches should be much cheaper than a single SLS and a viable option provided the biggest single load is propellant and transfer systems exist, either pumping fluids (sensible) or just attaching the tanks themselves (because despite talking about it for 40 years NASA still has not done any major LH2 transfer tests in orbit).
Spacex can beat SLS in the same way ULA beat Spacex. Reliability. IRL the only way to get good safety records is to launch lots of rockets (of the same basic design) that don't blow up.
Spacex has a manifest that will rack up those launches, in the same way that's it's racking up Dragon test experience with every cargo launch. At 1 launch every 2 years SLS will need to operate for a century to achieve the flight history of Atlas or Delta (IIRC DoD is looking for a minimum of 5 F9 successful launches to look at it for use on the EELV programme). . Just the 13 Saturn V launches would take 26 years.
But right now both FH and SLS are paper rockets. No I do not expect them to remain that way.
But logic does not drive the SLS programme.
Note 2 things. a) It's a *theoretical* material. b) It's only perfect till it gets to a *connector*
No one has made 2D Sn, much less 2D Sn funtionalised with Florine.
However Mercury Telluride has been made (I think it was used in IR detectors but better materials exist) and seems to verify the theory, or at least part of it. I'm not sure if that included the 1 atom thick layer thing.
The trouble with these calculated materials is the calcs are complex and approximations used. So the effect works great in a perfect lattice but IRL....
But what happens when you want to tap the flow and direct an electron flow (I know, lets call it a "current") into something more useful?
No mention of what happens at that point.
Thing is if this is a perfect conductor then (by definition) all else is imperfect, so there's a discontinuity interface. "Stuff" happens at such interfaces (typically rectification in semiconductors). Rapid heating as electrons "bunch up"? Infinite impedance IE no electrons exit the material?
B**gered if I know.
And note also 100% efficiency <> infinite capacity. At some point the # of electrons you're injecting into the layer exceeds a threshold and "stuff" happens (again). What's the threshold, what's the effect? See previous comment.
IRL on chip conductor layers have holes punched in them to allow signals (including power) to contact the processing layer from above. IIRC (I'm not current) this is at least 8 layers.
So I'd call it V 0.05 tech at best. Lots of potential but that's about it at present.
"Stanene? Really, stanene? I don't care if it converts oxygen into platinum, I don't want to design anything with stanene in it. Scientists the world over are terrible at marketing, how are they going to license something with a name like that?"

You can bet *that* was an MBA a**ehole made that decision
Sysadmin: He found a flaw in our security and accessed the crown jewels of the company
MBAA:So what, it wasn't in listed in the rules and we don't have to pay him.
Sysadmin: He could have sold the code to a competitor, inserted trapdoors or actual malware in it.
MBAA: But he didn't (thinks:Because he's weak and trusting. I would have shown no such "mercy.")
Sysadmin: You are kind of an a**ehole aren't you.
Remember Vaizey counts all those internet radio users as "digital" so 50% not so tough
Which is of course complete rubbish relative to actual broadcast digital radio.
"Although organ donation availability is by far the top driver for synthetic organs, there is also a strong argument for autoimmune compatibility and the ability to match the organ sizes. "
The technique of taking an existing organ, washing out the cells and using it as a template for precursor cell growth (from the patient) avoids the autoimmune problem.
Once you don't need a cell match for the organ itself you can concentrate on getting one the right size and shape. I was amazed at how much of the organ is not actually made of living cells, and could survive them being washed away.
Of course once you can have "custom" organs built for you with no rejection the possibilities are limitless....
Personally I've always wondered why people don't make more of an effort with eyes. Complex, lots of faults, and plumbed straight into the brain, yet the best that can be done is corneal transplant, which TBH, is a bit lame.
I think it's obvious that "Stuxnet n" (whatever version they are really up to) is inevitable.
Demonstrated capability X underemployed development team X list of assorted "bad guys" --> massive opportunity for kudos
Albeit secret kudos, but hey, those who matter know, and that's all that counts, right?.
Like the NSA's and GCHQ's desire to read and record everything this has nothing to do with reality but the perception of threat and the availability of the technology.
They will do it because they can do it.
The question of course is who *wrote* those laws.
Quite often it was accountants.
Seconded from one of the "Big 5" accounting firms
Who then go back to lecturing "Continuing Professional Development" courses for other accountants.
On tax avoidance. Or would you prefer "income protection"?
Remember it's all legal.
If you don't switch then the incompetent or dishonest not only continue with their existing behaviours, but you continue to reward them for it. Better to take a chance, in my view."
Damm right. thumbs up for saying it.
I saw a statistic that only 35% of all utility company users switch.
And I think the proportion of people switching bank accounts is much lower.
AIUI that's a churn rate mobile phone companies dream of having.
Any talk about "customer satisfaction" or "Customer service" is basically b**lcks.
That will only change when customer realize that customer "loyalty" basically means the right of the bank to screw you sideways
"What's the book?"
Don't remember, I was put onto it by a Usenet post but since Google's usenet search is FUBAR'd I can't find it.
IIRC it was written by a senior engineer with an instrument maker in the US. It started with how do make an acurate surface reference to begin with (you need 3 surface plates, some fine powder, a scraper and lots of patience) and went on from there. I think part of it was a case study about designing a Coordinate Measuring Machine, but I may be conflating 2 different books.
It dates from the late 80s or 90s as I referred someone else to it about 10 years ago.
Sorry I can't be more helpful.
The classic method for reducing disturbances is (essentially) to put a box in a box. Maintaining a temperature of 1 Deg C over the range of say 0-50C is tough, but doable. A box inside that could then maintain a temperature of say 1/50th of 1Deg. The principle applies to any disturbance.
I found RV Jones "Instruments & Experience" a fascinating read on instrument design.

Re: not rocket science
"That's what the Desertec consortium reasoned, "
I think you'll find that Desertec's plan used solar thermal, which is an efficient way to harvest all of the solar spectrum by heating a working fluid to high temperature and hence drive a pretty conventional steam turbine.

Re: I Googled German Goo Girls
Well, if you go looking for trouble.....
There's a book on instrument design that makes intresting reading.
One of the key items was maintaining a uniform temperature.
In this context that means uniform ant quiet, which is even trickier. The aircon is pretty special.
But note that surprising levels of vibration abatement can be achieved quite easily..
People were astonished when a few years after IBM developed the AFM someone built one in their garage.
They built it on a table loaded with sand sitting on 3 piles of old car tires laid out in a triangle (helps with the kinematics).
However running observations taking days calls for something much more serious, hence this puppy.
Thumbs up for an interesting article, but could have been a bit more informative.
