  1. Re:They're adding IDN support NOW??? on 'Lower Rights' IE 7.0 Coming · · Score: 1

    That's good to know. Although I still don't see how Opera's method is considered a solution. Correct me if I'm wrong, but from what I heard Opera still turns it off for .net, .com and .org top level domains. Those still need to show the properly rendered code because of the high spoofing risk that punycode represents.

    What is needed is a way to easily show both versions (for instance in a bubble on mouseover, with a very distinctive addressbar colour change, to let encourage people to mouseover, or some other better idea, cause I'm not the most imaginative person around) of the address. Turning it off for some of the domains (particularly the most common domains) is not going to work any more that the current temporary solution.

  2. Re:They're adding IDN support NOW??? on 'Lower Rights' IE 7.0 Coming · · Score: 2, Insightful

    Anyone heard if Firefox is going to implement a true solution? Turning it off is just not acceptable.

    The only thing that turning it off does, is remove chances of spoofing a URL that has not international characters at the cost of increasing the spoofing risk of those that genuinely use international characters in their domain name (and YES those are needed. Not everybody speaks, nor wishes to speak, English).

    The result of the current solution is that pages with genuine foreign characters show up as punycode, that is to say: "gibberish". Gibberish is very easy to spoof. If I have to distinguish between http://www.xn--espaa-rta.com/ or http://www.xn--espa-rta.com/ or http://www.xn--espaa--rta.com/ or http://www.xn--espaaa-rta.com/ I could easily be fooled. There are URL that are much much more cryptic than this simple one, but it makes a good point. All a phisher has to do is use a URL that looks like one of those, with . Turning it off is NOT the solution. Maybe showing the proper URL (i.e. http : // www. españa.com) but with a different color ( for instance red) as a warning. Or make it pulsating or something to warn us that it contains IDN characters, and on a mouseover have a little popup showing that punycode text that corresponds to it. This should make it easy to spot the spoofed address that should not contain IDN characters (or not the ones expected), without making it so much easier to spoof the ones that do use them legitimately.

    Because, once again, punycode is EXTREMELY easy to spoof. Longs strings of apparently meaningless gibberish are hard for the brain to assimilate. A simple name when properly rendered now instead looks as difficult to remember, and distinguish from a spoofed address, as a purely numerical URL. It is NOT as solution, only a temporary patch.

    I will therefore suggest that the IDN spoofing vulnerability is STILL present in Firefox. The type of URLs likely to be spoofed are the only difference.

  4. Re:I'll believe it... on Cold Fusion in a Breadbox Instead of a Bottle · · Score: 1, Informative

    Peer review is not the only measure of a thing's veracity. Unfortunately, there is a great pressure to conform to what is accepted by the peers (or be discredited). It does not always happen that scientists will only base their opinions on recorded data. Preconceptions, credibility and politics come into play.

    Cold fusion is an excellent example of it. Fleishman and Pons were not physicists but electrochemists. Controlled, fusion (by conventional high energy means) producing more energy than it consumed is still elusive (although correct me if I'm wrong, I think they managed to get slightly passed breakeven). Imagine the politics of having "newbies" in the field (as any physiscist would put it), manage with much less material investment what the best minds in the field haven't managed for decades and enormous investments. Before "peers" (or in this case, physicists, not their electrochemist peers) would accept it officially, they needed to have a theory... the numbers could not be accepted without a theory (which goes against the tenets of science, where if your observations do not match what the theory says, you have to start thinking if your theory is OK).

    It wasn't trivial to reproduce the results. The proportion of electrode atoms and deuterons in contact had to be exact or from a 100% reproducibility you quickly fall to 10% reproducibility if you only have 90% saturation. But in the early days, much was still to verify... and because the peers couldn't accept the numbers you couldn't get favourably peer reviewed, although enough others got similar results to suggest that something was indeed happening, although it might not be trivial to reproduce. If it hadn't been for the media coverage, the whole thing would be dead now. Nobody would have heard of it, since it would have been killed before being published in a peer reviewed journal.

    It does have striking similarities to the problems with fission. At first, uranium nuclei were bombarded with accelerated protons, but the energy threshold required to cause fission was too high. It was because of Leo Szilard's idea to use the neutrons to cause a chain reaction that fission was eventually made useful. Because Szilard was a physisist, and he had come up with the mechanism first his ideas were more readily accepted. The relative investment of time and money into fission was not comparable to the amounts invested in fusion. Other than that, the problem is similar. Breaking even is difficult when you ar trying to push protons together. finding a way to lower the threshold is the key.

  5. Other (more detailed) article and summary on Fighting Cancer with Math · · Score: 1
    I have found a more detailed article about the same research, where they explain the details of the study and the mechanism through which therapy was devised to fight tumors. There is only one human study, which wouldn't amount to much. It is however indicative that the conclusions obtained from extensive studies on rats, where 80% to 90% of the animals were treated with success, is not specific to that species.

    The link to the page is, for those who speak spanish:
    http://www.dsalud.com/numero65_1.htm

    For those who don't I will try to summarize what I consider the outstanding points presented:

    What they found in vitro is that the dynamic of grow in all tumors is the same. There is a dominan mechanisms for all types of cell lineages. The main mathematical characteristics of the dynamic are:

    1) Most of the cell activity of the tumors is concentrated in the external layer.
    2) There is a superficial diffusion on the edge of the tumor. The new tumor cell genrated from cellular division migrate on the surface of the tumor until they find a concave location where they are surrounded by a greater number of canncer cells than in their original position.
    3) The growth of the cancerous colony is constant in time, except in the inital phase (when there are few cells) when the growth is logically exponential.

    That the proliferation is restricted to the edge of the colony means also that the inner cells do not proliferate at the same rate as the external ones. There is therefore an cellular inhibition mechanism of the cancer cell similar (and later we discovered that is was practically the same mechanism) to the inhibition through contact that is seen in normal cell (non cancerous).

    The next step was to confirm that the same type of mechanism also governed the growth of the tumor "in vivo". We did several studies on fifteen different types of tumors from which we took several histological sections, and saw that most of the growth was always limited to the edge of the tumor. Also "in vivo" the fundamental characteristics of the growth dynamics observed "in vitro" have been confirmed. The fenomenon was therefore the same as in the "in vitro" case. The morphological parameters measured in the colonies were also present in the "ín vivo" growth.

    Most of the duplications of tumors occur on the periphery, and the peripherical cell have therefore much higher mutations rates. Where traditional models expected 32 cell divisions to result from the division of the cells from the tumor for a given growth, 800 divisions were actually occuring at the periphery. This also explains why metastasis cell are so much more aggressive since they consist entirely of peripherical cells.

    One of the main questions they had was why the new cell would migrate to the hollow areas where competition for nutrients is fiercest among tumor cells, and where the PH is highest as a byproduct of cancer cells' metabolic activity. They would have expected them to migrate towards the high peaks. The results of the study suggests that pressure from the surrounding normal tissue inhibits the growth of the cancerous cells. They therefore migrate to these zones of less pressure. Also, contrary to traditional views, the tumor destroys the surrounding tissue before invading it (through the high acidity resulting from the metabolic activity of the cancerous cells and the secretion of other compounds), instead of invading it before killing it as was commonly believed.

    As for treatment, they discovered that the body's natural defences agains this growth mechanism are the neutrophiles, one of the 5 types of white blood cells. These neutrophiles can withstand the high acidity surrounding the tumors and they can be in intimate contact with the cancerous cells. In test on lab rats, they created a neutrophilia (high concentration of netrophiles) in the tumor area by stimulating their prod

    "common sense" can be used to explain all sorts of conflicting ideas.

    I couldn't agree more. A prof of mine told us a story about the dangers of "common sense" once. As a structural engineer, he had been contracted to design a cover for a terrasse for a cafe somewhere. The owner wanted open space, and so he designed it as a cantilever, only supported on the building side, with no column at the other end. In such a configuration the beams of the cantilever will be in tension on the top part, and compression in the bottom part. Concrete doesn't do very well in tension so you put more reinforcement in the top part. Case closed.

    The contractor who was doing the job, had no experience with cantilevers. He managed to convince the owner that it would be safer with columns at the other end. And the owner agreed. Who could argue that a roof would be stronger with columns at both ends of the span? It's common sense, right?

    What they failed to take into account, is that now the stress patterns were the opposite of the design stresses, with tension on the bottom of the beam, and compression at the top since the beam was now supported at both ends. They never consulted with the engineer who had made the original design, so of course after construction the beams shortly started cracking in the underside and the roof slowly sagged. It was forturnate that some steel reinforcement had been included for the compression part, or it might have failed without warning and there might have been victims.

    The point of the story was that "common sense" was very often based on our limited experience. Unless you know what mechanisms make "common sense" true, you might be dead wrong. It never hurts to be sure; to have proof.

    And of course, as ou pointed out, the details of the study, the mechanism of what is happening is often what the research is all about, but also what the journalists like to skip.

  9. Re:This one is priceless... on 2-Year OpenOffice High School Case Study · · Score: 1

    The one issue you will find is that OpenOffice.org has crappy charting capabilities and they are not compatible with excel's chart. OpenOffice must have all the X in the same column, which must be to the left of all others, and the order of the subsequent data series is set from the leftmost to the right most. Even if you would like to show them differently in the legend, you can't. As far as I know you cannot set the labels of the legend manually. And when in Line mode for X-Y scatter, you cannot change the area and border of the symbols individually.

    Since Excel allows you to choose arbitrary columns for your X and Ys, many charts will not translate properly. In my particular case, since even in my Excel days I had stopped using its limited charting abilities for more flexible tools like gnuplot (I run many tests, and if I need to change the format of 100 or 200 graphs so they match, I like changing a couple of lines in a single gnuplot file and let the batch files update my whole report or thesis, and having better scientific (and 3D) plotting to boot) it hasn't made much difference, but if you have lots of charts you will have a harder time to switch. I still haven't been able to access Chart properties through OpenOffice macros, so overall its chart handling is it weakest feature.

    That being said, the fact that it handles previous versions of MS Office documents (particularly Word) much better than different versions of MS Office programs do, is the main reason why I have managed to convert several of my fellow grad students to OpenOffice. After one of them spent most of the day trying to make a Word file compatible with our supervisor's, I asked him to send it to me, and I basically opened it (did very little to fix it) and sent it to our supervisor who had no trouble with it. That was it. 5 minutes tops. He went to his office, cursing Microsoft, downloaded OpenOffice and I never caught him using Word again. He still often uses Powerpoint and Excel (force of habit mostly), but he is slowly drifting to use OpenOffice Impress and Draw. Since I converted him to the use of gnuplot I have good hope that he will not feel the need to use Excel one day soon, but to each his own rithm.

    So basically, if you are big on spreadsheet graphs, you may have some big issues (I'm trying to work on a macro on my spare time to easily create charts in OpenOffice using gnuplot as a back end and storing all property information in the graphic object's name, for later easy editing). If not, welcome to OpenOffice. It does a very good job importing and exporting equations too.
