Amazing how few programmers use real maths.I bet many of you have never done any real floating point work. I cut my teeth learning how floating point was implemented from the ZX spectrum ROM disassembly, used so many numerical recipies code for my Physics PhD, entered the world of programming for a living, and sadly never had touch maths commercially again. Most computer job I see advertised, seem to think that A-level maths is as hard as it gets. Enough moaning.
As a programmer, the one most important thing you need to know about floating point is never test for equality (even with zero), almost define how near the answer need be, and test against that. double a,b; double epsilon = 1.0d-10;
if (a==b){
if ( abs(a-b)

Re:Hubble vs James WebbThe James Web telescope isn't competing with or replacing Hubble, the JWST is an infrared telescope, and will see completly different things to Hubble, including the very first stars and galaxies whos light was been red shifted down to infra-red.

Re:ahh yes, the "Devil Particle"Funny April fool, but done, over at that scienfic blogging they had the LHC discovering the graviton. Paleo particles, dinosaur hadrons, thats funny. Not LOL but funny. I have to be Pedantic though, Top quarks don't live long enough to be bound to anything else.

Would prefer JavaI'd prefer Java to be packaged with Chrome. In the late 1995s we assumed that Java applets would be the future of the web. Its still a good technology make fast by the evolution of computing. Its just getting java packaged with browsers, was the shortfall.

The article started Face, how hard are guestures?I would have thought gesture recognition would be relatively easy just moment the position of hands, which should be the nearest object. But its taking some time. Certainly having a computer recognise basic hand movements and running scripts accordingly would be get timesaver. On the subject, when will windows get a proper scripting language, like Rexx was on OS2 and amiga?

1 and half year late and half powerGood luck to the physicists at CERN, delays have certainly hurt them, but I hope these collisions make for a solid physics run.

Re:Can of Worms?Well now, there be an easy test, for the disease, but no cure. But in principle finding the gene, does lead to a cure relavitively easierly. If the broken gene, needs to de activated then the physicians can use RNA interference to de activate the gene. I the broken gene, is something important missing then in principle, gene therapy, insertation of an other copy of the gene, using a retrovirus should cure the disease. I say in principle, neither RNA interference nor Gene therapy a proven technologies yet.

Seems odd to be keeping PhPThe data of course is the taxed part of structure, depend as it does on how much previous activative there has been on the subject at Digg, but it seems strange to still be keep the other parts of LAMP, and not to moving to a structure its everything is clustered, the including the web server and the application code. Cassandra is based on Java, and storing map and objects, it would make sense to me if they over from apache and php, to apache tomcat, or maybe glass fish. I guess now we'll all have to have Cassandra on our CVs to look professional.

Re:Unintended consequencesThere was a thread just today on Augmented Reality, the same tech that allow a phone to add location data to what you see, is the same tech that allows other people to watch where you are, and what you doing. Or course its in the hands of the nice Apple guys, how would never stop a user controlling modification to his own phone, oh whoops.

Instant SuccessI wonder if, companies are paying to get listed google apps. Its almost like advertising, and likely instant success for companies that get listed. I think I'll think about moving my apps, to some google cloud, if it get freely listed for that. Some of the listing, like dimdim for example, have been appended with, whats the connection to google apps.

Re:cancer worriesPatients of the company probably know that they be guinea pig, which won't be much consolation if the come down if cancer. Stem Cell Medicine does need the safety testing, it won't be until thousands have had it and aged, till we know how safe it is. I hope safety fears don't put people off research stem cell, almost all of us, could potentially use it to slow the aging process. There must be ways to test for damaged cells, and perhaps even engineer for reduced rates of cancer in the cell lines to be transplanted.

Life Streams and Feeds17. There is no clear way to blend two standard websites together, but it's obvious how to blend two streams. You simply shuffle them together like two decks of cards, maintaining time-order — putting the earlier document first. Blending is important because we must be able to add and subtract in the Cybersphere. We add streams together by blending them.

This guy is half way to inventing my Feed Distiller, except he didn't see the usefulness of similarity filtering to some source, to keep the stream on topic.

Organic MoleculesIts not exactly new that organic molecules and precursors of life exist in the Orion Nebula. Radio telescopes have found them since the sixties, and the Orion Nebula is an especially easy place to detect such compounds. Still the Herschel satalite, can view Nebula in unpresidented detail.

Alice and ScienceThats interesting news to me, that Alice was a statire on maths, and i'm not sure i believe it. But at least one scientific hypothesis, that of the red queen, has been named after Alice in wonderland. The red queen hypothesis, is
"For an evolutionary system, continuing development is needed just in order to maintain its fitness relative to the systems it is co-evolving with."
Named of course after, alice's meets with the red queen, where she has to run as fast as she can, just to stand still

Re:Crappy frameworks, tools and web standardsNot surprising, the web is an evolved system, stuck with backwards compatibility to ancient browsers. The GUI layers is even worse than you stated, because these days its AJAX and javascript hand written on top of the CSS. JSP is actually nice compared to all the other scripting languages.

Re:Programming == Cut & PasteI have to agreed. The more libraries you know, the more powerful you are, and a better programmer you will be. A good library will let you program in ways you simply might not of thought of. A recent example i found blocking queues in a java.util.concurrent. I wouldn't have thought of building a library to do that, and previously I was just polling a list. With the queue system suddenly i've saved lots of CPU time and at the same time, built more robust code.

Wishing thinkingI'd love the Shuttle to continue, and some new launcher to take its place, but I can't realistically see it happening with so much US debt at the moment. Of the Ares launchers, presumablely the Ares I would be the one to stay, but its heavy lift launchers that the world is short of. Plus there is the spectre of another Shuttle disaster hanging over any plan to extent the shuttles life span.

Bad for photos, good for weatherA tumbleweed rover, would stand still, at some odd angle for weeks between storms, then get blown so fast, all the picture would have motion blur, (unless they put a very fast camera in it). But it would be great for weather sensing because it would detect every gust of wind.

Re:Sitemaps?Yes, a good site map, lists the last changed date for each page. Google reads the site map for each site first. So the above Author is right the PUSH system is already integrated into sitemaps in the last Modified and changed attributes, and no new protocols or hubs systems are needed.

Hard Disks are best densityHard Disks have risen in density so far, that tapes and optical drives just haven't kept up. I should use a RAID 6 array of the disks with the best bits per buck score, probably 500GB right now. If its very important consider have a copy server with the disk colocated at a rack space provider.
