  1. Delphi Components on Outstanding Objects (Developed Dirt Cheap) · · Score: 1

    Commonly overlooked in this kind of c/c++/perl focused discussion, but delphi's component model has been in operation ever since Delphi 1 back in the 90's, and has produced a most successful mix of freeware, shareware and commercial components easily and simply plugged into the development environment. Torry.net gives a good flavour (http://www.torry.net/). Also the Project Jedi code (http://www.delphi-jedi.org/) is now an effective extension to Delphi itself.

    "and can talk to all those other databases via ODBC."

    My one experience of this was quite nasty in that we had a legasy app using foxpro back and front ends that we needed to convert so the data would run inside sqlserver (to integrate it with the rest of the business) and leave the front end in vfp. In theory just a case or ripping out the direct data accesses and replace it by odbc calls.

    Now I'm not a vfp expert and wouldn't pretend tpo be, but I found this a nightmare, predomonantly because a modern rdbms like sqlserver is not compatible with the old vfp data/index file way of doing things. Much of the code inside the app used indexes to sort data views, process through datasets etc, all of which needed to be rewritten for an environment where indexes are not directly accessible.

    Well taking the US figures are a bit misleading as so far the US is reporting no local transmission of SARS. Indeed the WHO is to date reporting no local transmission anywhere outside those countries where the disease was endemic before it was recognised as such. That's not to say it won't occur, but the fact that it's not been reported so far a month on from the WHO declaring the disease a global threat to health should tell you something. Excellent review article on the WHO site at http://www.who.int/csr/sarsarchive/2003_04_11/en/

    The infection rate for any disease is a combination of how infectious it actually is and how effective isolation measures are. Of course SARS has a 'natural' infection rate of much greater than 1.0, but so far it seems to be being kept at a level around 1.0 by containment measures. Of course that's an average - that WHO report goes into considerable detail.

    Obviously SARS is a major and serious problem with the potential to kill millions, but it's too early to call yet as to what the eventual situation will be and a global pandemic is by no means inevitable - or indeed I would suggest the most likely outcome at this stage.

    There is a good side to this.

    SARS is has a mortality high enough that it's serious, and is infectious enough that while it can be controlled, it's a challenge to do so.

    It therefore gives WHO, CDC etc. a dry run. Better to find out what's wrong with their epedemic control procedures now rather than if something really nasty pops up later.

  9. Re:Why this matters on Webcams to Enforce Singapore Quarantine · · Score: 1

    Most of your comments are excellent, EXCEPT that SARS is nowhere near as virulent as flu.

    If it was there would be several million cases by now. SARS is actually down the lower end of the spectrum for infectious diseases, which gives hope that it can be controlled.

    By way of example take measles and smallpox. If a lecturer with measles walks into a lecture theatre with 100 students at then end of the lecture all 100 students will have measles. The virus is airborne and shed from the skin and is *that* infectious.

    By contrast to pass on smallpox he'd need direct skin contact. SARS is down the lower end of this spectrum too - less infectious than smallpox by the look of it and certainly much less infectious than flu (which is nearer the measles level).

    Another helpful factor is that indications are that SARS is only infectious when symptoms are being displayed.

    As WHO point out, since the infection was recognised there has been no cases of uncontrolled outbreaks in any country where it wasn't present beforehand. Vietnam has also effectively controlled it's outbreak and almost ended it (they though they had but one vector got through).

    In all probability the HK and China outbreaks will be controlled and it's unlikely to cause an uncontrollable problem in the first world thereafter. The danger lies if it gets into a third world population and becomes endemic, which will result in permanant draconian measures in the first world to catch infections until a vaccine is developed,

    I've posted a detailed comment under another thread about reinfection rates, but I don't think I'm disagreeing with you. SARS is not particularly infectious, and with a reasonably ordered society and health system then measures can be taken to reduce the infection rate to below 1.0 and the disease can be controlled.

    My point is that it is sufficiently infectious that if it gets into a population where these are not available then infection rates will soar and we will have serious problems. For example imagine a superinfector walking around Baghdad at the moment.

    What's remarkable about these is that the rate of increase is pretty constant. This implies that the disease is generally not that infectious and the average rate of infection (the number of people that an infected person infects) is currently hovering around 1.0

    Obviously this is complicated by the discovery that there seems to be superinfectors (some people have been traced as infecting a dozen or more new people) whilst others don't seem to pass on the infection at all. However the critical number is the overall rate of infection. Obviously if this is greater than 1.0 the infection increases exponentially, at 1.0 it's linear and at less than 1.0 it just dies out.

    The aim of any epidemic control task is to reduce the infection rate below 1.0. Humans are not fields of wheat and can modify their behaviour to do this. For example take the other scary outbreak disease Ebola. Experience shows that when an outbreak of this occurs initially infection rates are high - 5 or 6 or more - as tribal practises for cleaning dead bodies result in numerous infections. However once the outbreak is identified and people given correct instructions infection rates fall dramatically to well below 1.0 and the disease burns out.

    Obviously the nature of how the disease is spread influences how effective behaviour modification can be. For Ebola it's stunningly effective as the disease only passes by direct blood contact. With SARS it's more difficult, but it's not going to be impossible. Diseases like flu and measles are so infectious that they cannot be effectively controlled.

    "double every 7-8 days"

    eejit. If you look at the figures the rate of increase is pretty constant, and in fact has been dropping over the last few days. Also don't forget that the WHO's figures are culmulative. At the moment there's only about half the total actually sick (1333 as of today), the rest have recovered or are dead.

    Actually the constant rate of increase is the *hopeful* sign in the stats. If it was flu or something similar then the increase would be exponential. As it is it continues to be health staff predominantly infected, which imples a slow rate of transmission

    Jeez. It's not highly contagious in the same way flu or measles is, but it's pretty contagious and the only way to handle it is by an intensive response NOW.

    Fortunatly at the moment it's *just* being contained. Indications are that carriers are only contagious when they visibly have the disease, so by intervention it can be controlled. But if it gets out into the teeming masses of India, Nigeria or the like within the next 6 months then expect to see hundreds of thousands infected, several tens of thousands of deaths and travel restrictions in the first world like you would not believe.

    Also viruses like this that has just jumped the species barrier tend to be unstable. Fortunatly experience shows that the tendency is towards mutation to less lethal strains, but it ain't necessarily so and it's prudent no to give it hundreds of thousands of hosts in which to experiment with potential mutations.

    Bottom line is that this is not the next Spanish Flu yet, but it has to be treated very seriously indeed. As WHO say it's unlikely now to go away completely and until there's a vaccine (read 3 to 5 years) the world will need to keep on top of it wherever it strikes or else there will be a lot of dead people and striken economies around the planet.

    *British Telecom regularly seem to leave something to be desired when it comes to 'public service'. A friend of mine has this story about how he recently installed an ADSL modem for a business in the centre of Glasgow - a city of nearly two million people. Naturally he assumed that ADSL would be available so neglected to explicitly check, and he was consequently scunnered when BT told him that it wasn't available due to 'insufficient demand'. Apparently the local exchange serviced quite a small area, and one where there was a disproportionate number of warehouses and areas under redevelopment, so despite being right in the middle of the city it had not met BT's criteria. Fortunatly given where they were the embaressment factor was sufficiently high that BT upgraded the exchange anyway, but it just demonstrates what we're up against.

    I don't disagree with this completely, but, to be honest, sometimes war isn't political, at least for one side anyway. I think there's definatly a situation where it could be self defence and survival, not political.

    I think Clausewitz would say that self defense and survival *is* politics. However the pertinant point in this war is that the Baathists are fighting for survival, America is not, so in the final analysis America's will can be broken before the Baathists if the war can be extended sufficiently long.

    I see your point, but I still disagree. I don't belive the Vietcong "forced" anything like it. I think our leaders were simply morons who didn't really care and didn't listen to the military as to how to go about it.

    You make the error of seeing the war in purerly military terms. Clausewitz's assertion highlights that war must be seen as part of a wider political process. It really doesn't matter if the Vietcong won because they defeated America militarily, or because they made the cost of America winning politically unacceptable. The result is the same

    Militarily? Not really. His troops are really no match for the US/British toops. Yeah, the troops will take casulties, maybe more maybe less, but they'll still win....
    ...US troops look bad for shooting civilians that are being forced to shoot at them, and thereby try and sway public opinion against this conflict. But, that's not a military strategy, it's a political one.

    There is no difference. The political is military and vica versa. Not that this simple truth seems to have been grasped by the truly dreadful Donald Rumsfeld - a man who seems to posses the dialectic sophistication of Lenny Osborne.

    Following the bomb in the Baghdad Market this evening, and the consequent achievement by America in uniting all Arab opinion against it, I am now firmly of the conclusion that the Baathists will most probably win. Of sure, they'll be a battle and the republican guard will be defeated, but America will not be able to take and hold Baghdad in the long term without unacceptable political consequences.

    I'm not at all sure however this will apply to the whole country. The British experience in Northern Ireland may well stand them in sufficiently good stead that in Basra and the Shi'ite south a viable peace could be achieved. Similarly in the Kurdish north.

    To paraphraise Mr Banks...

    All the usual rules of uprising realpolitik will still apply, especially that concerning the peculiar dialectic of dissent which - simply stated - dictates that in all but the most dedicatedly repressive hegemonies, if in a sizable population there are one hundred rebels, all of whom are then rounded up and killed, the number of rebels present at the end of the day is not zero, and not even one hundred, but two hundred or three hundred or more; an equation based on human nature which seems often to baffle the military and political mind.

    We've been developing a couple of similar products for several years now. GenesisII attempts to create photorealistic images based on GIS data, and Landscape Explorer is a more traditional 'Image Overlay' product (there's also an online embedded ActiveX version). Site is at www.geomantics.com

    Both these programs are intended to take a 'feed the data in and get the image' type of approach rather than the 'build your world from blocks' approach you'd get with a 3D modeller application.

    With the 'Image Overlay' program this is relatively straightforward because the data is not that complex, but when you go for something more detailed and 'photorealistic' like GenesisII then complexity of the solution seems to increase exponentially with the degree of detail needed. For example modelling a mid to far distance mid-western US landscape is actually quite easy, doing it in Europe is vastly more complex because of something as apparently simple as the hedgerow and field pattern. Similarly really high mountains (Rockies, Himalaya) are easy, Mid range stuff with confirers is not too bad, but the real challenge is the English Cotswalds because of the shear complexity of a 3,000 year old mixed deciduous forest/farmed/grazed landscape.

    Even with Satellite data the problems on landscape are complex. Sure I can tell it's a forest, but is it Oak or Birch? It may not matter if I'm viewing from a long shot, but closer up it does. How do I tell? get better data? (available, expense), guess (ok for games maybe, but it's not reality), or use an algorithm (you have an tree/soil/landscape distribution algorithm to hand?)
