BrianH 11-Feb-2011 [5722] | I've already started the research, bought the phone and such. My limiting factors aren't Carl. And I don't do the incremental development with frequent compiling style, I do the write it ahead of time style, so am not limited yet by not having a lib in hand. |
Reichart 11-Feb-2011 [5723] | ...Moving this conversation to....................hmm.............. we don't have a Group that nails this one....but I'm moving this to Android.... |
Henrik 21-Feb-2011 [5724] | Interesting comment on SSL libraries: http://www.varnish-cache.org/docs/trunk/phk/ssl.html |
GrahamC 22-Feb-2011 [5725x2] | http://edition.cnn.com/2010/WORLD/europe/11/18/switzerland.cern.antimatter/index.html 38 anti-matter atoms trapped ... I wonder if they'll let them go free? |
They've capatured anti-hydrogen .. next is anti-CO2 and then we can get rid of the excess CO2! | |
Ladislav 22-Feb-2011 [5727] | The above is in wrong group - should be in humour. |
GrahamC 22-Feb-2011 [5728] | Ladislav, you have no sense of humour! |
Henrik 22-Feb-2011 [5729] | getting rid of the CO2, one molecule at a time. |
GrahamC 22-Feb-2011 [5730] | But imagine the energy released when matter meets anti-matter ... has no one seen Star Trek?? |
Kaj 22-Feb-2011 [5731] | There is no sound in space, and there is no excess CO2 |
GrahamC 22-Feb-2011 [5732] | Ah .. the old Zen thing |

They're taking the timeframe of R3 development to implement a... test suite | |
Reichart 16-Mar-2011 [5735] | Perhaps we can use this THREE YEARS, to simply revert to somethign like xwindows, or even EPS, which simply works, and make a new web that vector and scales, and is small and fast. |
Kaj 16-Mar-2011 [5736] | That's called the Next, and the web was invented on it, so we're supposed to already have it |
Henrik 16-Mar-2011 [5737] | Reichart, that might have bigger ramifications than what we would immediately see, since many systems are (needlessly) rendered using heavy HTML engines, like the OSX dashboard. There are some big savings to make here by changing the Volkswagen of programming languages to something simpler to render. |
Reichart 19-Mar-2011 [5738] | That is what I had in mind when I wrote that. I still own both a BW and Colour Next. |
GrahamC 19-Mar-2011 [5739] | uh oh ... consuming the food/water near tokyo for a year is eqivalent to one CT scan ... not good |

Not trying to over load anyone, just showing that the Tech of this topic is "tricky". | |
Kaj 19-Mar-2011 [5746] | Seems simple enough to me. Wanna cool a nuclear plant? Throw water on it :-) |
GrahamC 20-Mar-2011 [5747] | And the heavier it is the better? |
Henrik 20-Mar-2011 [5748] | It's interesting to me that we don't have anything better or more efficient to actually throw the water with. |
GrahamC 20-Mar-2011 [5749] | Perhaps liquid helium is not available in large enough amounts? |
Janko 20-Mar-2011 [5750x6] | The height of our hi-tech is low. |
Can't they bring in like 10 in remote controlled firetrucks that would spray water and go out for refiling while next one comes? (they made ad-hoc remote controlled cars in myth busters so it can't be that hard) | |
and don't japanese have all kinds of robots? (I know ratiation can screw electronics, but it seems it's not that hard, those chopters and firetrucks that they use now surely rely on electronics too) | |
or just construct the pipes and pumps that would use seawater near to constantly water it? They transport oil across continets in pipes no matter how far the water is, they sould be able to make a constant suply in there. | |
or probably 100 other things that seem better than driving in with human controlled firetrucks and flying over with a helicopter pouring water on it. | |
at slight risk of looking like idiot: http://jankom-code.posterous.com/idiots-3-minute-solutions-on-cooling-down-the Idiot's 3 minute solutions for cooling down the reactors in Japan | |
Henrik 20-Mar-2011 [5756] | There is probably no money in developing equipment for handling nuclear accidents, if one only happens every 25 years, as it just adds to the cost of building reactors, reducing the financial incentive to build them in the first place. Also even though many reactor designs that are supposedly better than the current ones exist on paper or are in research, there is apparently not enough people working in the field of research and licensing to move such reactors into production. There are reactor types that work entirely with passive cooling and can be evacuated for 72 hours before anything happens, but they are still at the research stage. Putting the reactor in a big hole might be a good idea, but it depends on the location and how an earth quake would affect the hole. It seems that many of these accidents are due to very clear design flaws or overriding specific safety procedures. That's a positive thing, because it means, it's not impossible to build very safe reactors. |
Kaj 20-Mar-2011 [5757x2] | The only thing they seem to robotisize is a Dutch company they asked to make aerial photos with those remote controlled geek helicopters |
I thought those were always Made In China, but apparently the Dutch are good at making them seem high tech :-) | |
AdrianS 20-Mar-2011 [5759] | just so that we don't start feeling too smug about how things are done here in North America wrt nuclear plants: http://www.counterpunch.org/stclair03162011.html |

Kaj 20-Mar-2011 [5761] | That's good info |

GrahamC 29-Mar-2011 [5763x2] | Why not just teach Javascript? |
At least they can use it | |
Kaj 29-Mar-2011 [5765] | There are these rare messages where I sometimes think there is some sanity left in the world after all |
Maxim 29-Mar-2011 [5766] | unfortunately, what I call flat OOP (limited inheritance & polymorphism) is very effective and functional programming isn't a substitute for OOP. The fact that the page talks about OOP being anti-modular, IMHO, clearly shows a fundamental lack of understanding for that paradigm. the problem here is not OOP, its how people have granted it the "golden hammer" status that it never should have gotten in the first place. The problem is that people have diluted the core ideas behind OOP by bloating it out of its purity. When you look at the huge mess that are the current commercial frameworks like java or .net, then it does seems like OOP has somehow failed, but in reality, going back to basics and teaching how to leverage OOP properly would have been a better decision IMHO. |
Gregg 29-Mar-2011 [5767] | Hmm, a subset of C and ML. Maybe the anti-modular comment refers to modularity in the large, e.g. system modularity, which I agree with. I'm not sure about bloating out purity though Max. Yes, the three legs it stands on are easy enough to list as bullet points, but even early works (not going back to Simula's era) like Booch's OOAD talk about notations and other heavy additions, along with the view that we needed OOP to help manage complexity, because software is inherently complex. |
Maxim 29-Mar-2011 [5768] | when I mentionned purity I guess I should have used a more descriptive sentence. I really meant to say, objects, being used as objects. nowadays, OOP (the paradigm) is used for every part of software, even parts for which its ill-suited. OOP is not about the language, its about the logical step after structured programming. grouping things together. why stop at OOP, they might as well re-introduce the GOTO as a viable pattern. :-) OOP when its used without all the "advanced" object patterns, is incredibly effective... just look at the Amiga OS which was almost totally OO in its layout and use while still being coded in C. |
BrianH 29-Mar-2011 [5769] | I like the Go model to OOP: No inheritance, polymorphism based on interfaces, object-based concurrency. |
Gregg 29-Mar-2011 [5770] | I don't know that I would say *after* structured programming. Grouping by binding code and data together is not the only way, though it can work well. I think we're on the same page. And I agree with Brian. |
GrahamC 29-Mar-2011 [5771] | http://www.stuff.co.nz/science/4825382/Meteor-explodes-over-North-Island Missed it! |
