    Or get a bit fancier (which I suspect you'll have to) and list any email addys you challenge on a provisional whitelist and only move them over to the real whitelist once they've correctly responded.

    This allows you to get funky with the provisional list - add time expiry rules, move addys to a blacklist if they screw up the challenge more than a few times, scan the provisional list for 'spammy' IP ranges etc etc

    As with any arms race the ideal is to use layered defences and a mix of techniques, so whitelists have a part to play, but so do blacklists, reputational systems, cryptographic signatures and so on.

    [My three grandparent points snipped]

    I already addressed all those issues in earlier posts, and feel no need to repeat myself ad nauseum. Just because you learned something last week doesnt make it new, or news.

    Really? Where? All I see is a bunch of borderline flammage about a problematic Exchange upgrade and some dodgy COM implementations and then one post made after your reply to mine which missed (or ignored) the point of the original argument.

    Here's my third point restated more clearly:

    MSoft has acquired a defacto monopoly of the desktop OS.

    The monopoly on the desktop is a bad thing because it allows them to raise the barriers to entry for competitors and permits them extract an ongoing monopoly rent from their locked in customers. This is a market failure that leads to the less than efficient distribution of resources across the wider economy and, absent external intervention, it is unlikely to be self-correcting.

    Indeed the secure bastion of MSoft's desktop OS monopoly has permitted MSoft to extend its monopoly into the desktop application space and seek to expand into other nearby competitive areas (eg. servers, game consoles, peripherals etc). So not only is the monopoly not self-correcting it is actively seeking to grow more powerful and more dominant.

    Basically my contention is that Monopolies Are Bad, which has been a staple of economic theory since Adam Smith. Are you arguing contra?

    MS "tax"

    This term you guys cooked up is the dumbest fucking arguement Ive ever heard.

    That's probably because it is a term, not an argument. Its also not mine, which is why the thing has quotation marks around it. I prefer 'rent' as being a more accurate description of the situation (in a technical economic sense) - but you know that already 'cuz you snipped that bit out when you responded to my post.

    You are using something which fulfills a need.

    [everyday examples snipped]

    Likewise, paying for an operating system isnt some "Microsoft tax".

    No it's a "Microsoft Rent" (the excessive profit part of it anyway). MSoft are able to impose higher than market-rate prices by virtue of their monopoly lock in. Their customers (OEMs chiefly) have little choice but to accede to these prices (and other onerous MSoft contractual terms) if they want to stay in the computer business. Contrariwise, I have a great deal of choice when it comes to getting a haircut, eating out or having my car serviced, which is why the money paid for these products and services cannot accurately be described as a "hairdressing rent", or even a "hairdressing tax".

    MSoft's excessive profit is economically suboptimal and, left undisturbed, leads to a self-reinforcing concentration of power and wealth which is Bad-with-a-capital-B both for the economy and for wider society. I don't know how I can say this any clearer or simpler.

    You might argue about how much of MSoft's profits are a monopoly rent, but given their ability to steeply discount their products and services as soon as a significant customer seriously starts looking at alternatives makes it very difficult (IMO impossible) to argue that there hasn't been any monopoly gouging going on since the mid-90s at least (I would contend earlier but its a moot point).

    If you dont like it, go fucking use something else! MS isnt forcing people to use their OS. Just because third parties only program for MS proves the superiority of their platform; nobody wants to support multiple OS versions of the same product if they dont have to.

    Underneath the invective there are some serious points being made here. There are significant network benefits and efficiencies derived from having one (or a few) consistent technical architecture. The question is whether those advantages outweigh the consequential costs.

    it's fundamentally bad for the economy (it's limiting competition, and an artificial constraint on increasing effeciency, all of which are bad for the economy).

    I dont see how having people buy from a US company or get something free can be seen as bad in terms of economic competition. In that respect, people should be all for MS, because Munich using SUSE isnt bringing a single deuchmark into the US.

    Firstly it isn't deuchmark (or even deutschmark) - Munich is in the Eurozone these days.

    Secondly, IBM are acting as lead contractors on this migration so a certain percentage of those 35 MegaEuros will be ending up in Armonk, NY at some point along the line.

    Thirdly the grandparent was criticising MSoft's monopoly lock-in as bad for the small-e economy (ie on general economic grounds in that it is effectively a rent upon all economic activity) rather than the big-E economy (ie the US balance of payments). In any case why should a bunch of regional civil servants in Germany be bothered about the US economy when it comes to deciding their IT strategy?

    Second, I dont see that its artificially contraining effeciency, especially since the alternative isnt really going to make people work any faster.

    Efficiency is going to be lower if MSoft is able to command an ongoing monopoly premium on its software prices. The MSoft 'tax' (actually a rent) represented by their monopoly premium, acts as a general drag anchor upon the economy. The excess profits derived from this monopoly would be more efficiently utilised within the economy as reduced unit costs or increased profits for MSoft's customers and/or competitors.

    Of course distinguishing between MSoft's 'honest' profit and its 'excess' is a tricky proposition at the best of times - made harder by the natural human inclination towards rent-seeking (and the fact that this natural inclination is, in MSoft's case, bankrolled by an enormous warchest built up from earlier excess profits).

    If people exchanged documents in a more open format, it'd be a heck of a lot easier to migrate to a non-windows environment.

    And your point is? I dont see why people complain about MS using non-open formats. Why should they?

    Because they think that the MSoft monopoly is a Bad Thing economically (see above) and view their proprietary formats as a bulwark of that monopoly?

    Because they don't like the way that MSoft breaks their formats every few years in order to encourage people to upgrade their software?

    Because they don't want essential interactions with legal and governmental agencies to require the software products of a single company?

    Because they are archivists who want a document format that will be readable in 50 years time?

    ... using Mandrake 9.2 and there are some minor personal nitpicks for her:

    1 - initial impression of Gnome was good, but she immediately picked up on a tendency to laggy-ness. If it continues to grate I'll have to look at alternative graphical managers (I can sell the availability of alternatives as a plus of course).

    2 - her HP Jornada won't play with Linux so it looks like we'll have to keep the XP partition for the timebeing (suits me - I can use it for games that don't run under Wine...).

    3 - the scanner is playing up so that's something I need to troubleshoot over the weekend. Doing this sort of project while working away during the week is a major pain BTW - telephone calls from frustrated g/f and nothing to be done for 3-4 days *isn't* a good selling point.

    4 - she thinks the time it takes to boot into Linux is excessive.

    However the major roadblock (possibly a deal-breaker) is the f*cked up OEM version of WinXP that gets shipped with Compaq boxen these days. What it means is that after installing Linux, any time you opt to boot into Windows (to export contacts from Exchange ready for Evolution fer instance) it spots that the MBR has been altered by the bootloader and initiates the 'Recovery for Morons' mode (meaningful explanation of what is going on? nada; option to flip into an 'I Know What I'm Doing' mode and tell it to STFU? nope). The only options, apart from aborting and going back to Linux, are where to Recover from (partition or DVD) and of course either process takes 10-15 minutes, zeroes your box back to factory settings (bang go any security patches, config changes, user settings and the like) and blows out the bootloader (so you have to go through the Mandrake installation routine to reinstate Linux again).

    I gather that Compaq, or rather HP, are obliged to provide full installation media upon request; so that's the *other* thing I'm doing this weekend (beyond the valentines thang that is) and as soon as they arrive I'm doing a proper install and blitzing the recovery partition - I could care less about Compaq's warranty support...

    I'm an obstinate SOB however and do this sort of thing for a living; if Linux-on-the-Desktop really gets some mass-market traction in the next year or two I can forsee whole swathes of the general public hitting this Windows Recovery Tango on recent vintage OEM machines and running screaming from the Penguin unless some primers that cover this issue are made a prominent part of the online resources.

    PS
    Another gripe I have with XP (only 1?) is the Simple Security Model forced upon you by the Home Edition.

Anyone know how to get to it? Its not offered as an option during startup or shutdown at present.
