    Well, it seems like a lot of people would happily run financials via the web ... our company is moving to that from installed Windows apps, and it wasn't my doing, it was our CFO.

    I seem to remember a few years back being told by a Siebel sales guy that hosted software for sales CRM wasn't going to fly either, but I bought it anyway :-)

    You've worded it gently, but this sounds like your former boss was a little corrupt :-)

    When I worked for Mrs Queen, even with the most ehtical of intentions, we did have the issue that the open procurement system would result in unsuitable tenders (the process was run by procurement people who knew nothing about technology) and would cheerfully saddle you with nonsense to save a quid.

    So, we would tend to do an informal market survey first, talk to vendors, make a buying decision based on normal commercial business criteria (is this vendor competent? Is the product any good?) then load the RFP in favour of the best solution.

    The other issue that made things hard was that some procurements are inhrenetly single vendor - for example, what about renewing a maintenance contract for Sun servers? Sun's own Platinum maintenance is very well priced, so you'd be an idiot not to use them, but government procurement left unfettered will end up hiring Joe PC shop down the street.

  4. Solutions before ideology, even for non-profits on Selling Open Source Solutions to Upper Mgmt? · · Score: 1
    Fair disclosure:

    1. I'm the CTO at a leading vendor of high end online systems for non-profits. We have two CMS offerings. We may well be the "evil" vendor mentioned in this post :-)

    2. I am the worlds biggest fan of open source - I'm posting here, on my work laptop which, yes, I run Linux on, because I find it to be a better fit for my personal needs (mixture of hardcore techie and traditional business user) than Windows.

    We don't open source our software, we don't even ship it ... we deliver everything hosted "Software as a Service" ... why? Because 99% of non-profits don't have the IT resources to set up and run a complex, robust, clustered 24x7 web envrionment, and for the ones that do, we can do it better, faster, and cheaper, because we have economies of scale associated with doing it for over 1,000 clients instead of just one. The American Red Cross is like a Fortune 500, and has an IT department nearly twice the size of our company, but they use our solutions too.

    Customers don't need to develop stuff, or even set up servers, to get our product running. We can deploy a new site as fast as they can work with us on the content and business level concerns. On occasions, we've deployed new sites in under a week.

    We use almost all open source stuff in our production systems. The big exception is the database - we run Oracle, which costs a lot of $$$, because it *works*. We have the expertise to leverage this technology and make it work for our customers. Our customers can't afford to carry that skill set and staffing in house.

    Our business exists because there is a true need for a packaged
    • solution
    for non-profits. I'm sure the usual whiners on Slashdot will say that anyone who pays money for software is stupid or evil, but they're not - they just want to get stuff done.

    It does sound like the original poster is thinking first about personal ideology of promoting open-source, and not about the business needs of his/her employer.

    As many people have observed, this is nothing to do with OSS .... the real business decision here is "build vs buy", and it sounds as if the organization's ED and board have made a good call.
  5. Difference between servers and desktops on Why You Can't Buy a Naked PC · · Score: 1

    We too buy Dell servers bare or with a Linux preload (which we flash and reinstall anyway so we can load the RPMs we want).

    The cost of the Windows 2003 Server license is indeed about $800. However, the article is about desktop/laptop Windows licenses ... for a consumer machine, the only thing Microsoft provides is a licnese and a sticker, and Dell only pays $20 or so a machine.

    Servers are a whole other world...

    1. There is much more demand for Linux on servers
    2. Generally, people like us who buy them know what they are doing
    3. There isn't a need for drivers for a whole bunch of cheapo Tiwansese hardware like USB webcams and printers

    Dell has been offering Linux either bundled with, or pre-installed with, on **servers** for a long time - they even have a 3 way agreement with Red Hat and Oracle to certify particular configurations and support each others products without any finger pointing.

  8. A couple of non-obvious notes about radix sort ... on Sort Linked Lists 10X Faster Than MergeSort · · Score: 2, Insightful


    1. Although it's technically O(n) compared to QuickSort's O(n log n), consider the fact that

    a. the number of passes required by radix sort is proportional to the key size, and that
    b. if the keys are primarily unique, then the key length will be O(log n) .... thus radix sort is actually O(n log n) when applied to practical cases, hence why everyone uses quicksort or mergesort instead.

    2. One cute feature of radix sort for very large data sets is that you only need linear access to the data, so it can be done with non-random-access external storage. The one practical implementation I've ever heard of used four 9-track tape drives.

    However, considering use in main memory, both radix sort and quicksort make efficient use of a D-cache that is 2-way set-associative or better, and both hit the whole data set once per pass -> if it swaps, it'll swap a lot :-)

    There is something very wrong with your fuel consumption measurements ...

    Although there is a certain overhead due to the inefficiency of a petrol engine at low RPM, at those kinds of speeds, fuel consumption is about linear with power, and air resistance is the dominant use of power.

    The power required to keep a car moving at a given speed against air resistance goes up as the cube of the speed, while the ground covered increases only linearly with speed. Thus, distance covered per unit of fuel (mpg) is reduced quadratically with speed.

    At 90 mph you get a lot less mpg than at 60 mph.

    We do get some servers preloaded with RHAS but we tend to config our own installs of that too - Dell's config people don't always "get" non-desktop IT (example: order dual channel hardware RAID controller, and they'll create a RAID-1 LUN with both drives on the same SCSI bus), but to be 100% fair I prefer us to reinstall any server system just to (a) get it exactly the way I want it, and (b) to be sure we have the knowledge to do so.

    A very common form of DDoS attack is a SYN flood where the source IP in the packets is NOT the IP of the bot being used.

    Last time someone had a go at our servers, the forged IPs traced back to well known locations which obviously weren't the real source (mostly US government labs like LLNL and Sandia).

    I see a risk here where DDoS is used specifically to frame the real owner of an IP.

    The DC is 24V, which is not high voltage in anyone's world. The ring signal is a bit more, IIRC 120V AC which I have gotten zapped by once :-) There were older phone switches (1970's) which did NOT provide the 24V DC power, and where a customer premises power supply was needed for outgoing calls.

    An analogue phone line works entirely off the two wires, as many posters have noted the second pair is normally used for a second line, or is left open.

    The red / black / green / yellow colour scheme is only used for endpoint cables (those silver ones) and, unusually compared ot other wiring standards, they actually flip over and pins 2-3-4-5 connect to 5-4-3-2 respectively.

    Once you get into the real wiring, typically RJ-11 jacks in a building will be wired with the USOC code ... like most telco wiring codes, this is based on pairs; the insulation on each pair has a complementary colour scheme, where the first wire is mostly white and has a coloured dash, and its partner is mostly coloured and has a white dash.

    For an RJ-11 phone line under the USOC scheme, pins 4&3 get "Wb/Bw" (white-blue, blue-white) and pins 2&5 (note the order) get the line 2 orange pair "Ow/Wo". Pins 1&6 get the green (if the cable provides a 3rd pair) or re left unconnected.

    For ethernet (Cat 5, 5e, 6) schemes like 508-B they use four pairs, the 4th pair is brown. Only GigE and up uses more than 2 pairs.

    In a trunk cable, there will typically be 40 pairs, carrying 40 customer lines ... once they use up all the main colours with white, IIUC the next batch of pairs are based on either grey or red.

  20. Understanding the Economics of the "GooTube" deal on YouTube Removes Comedy Central Clips Due to DMCA · · Score: 1


    Google's stock went up by more than $1.65b in market cap the very day they bought YouTube, which was done as a pure stock deal. This means that while Youtuve's founders, investors and staff still made a pile of money, it was effectively free for Google. Since that time, their market cap has gone up another $15bn or so, and a good proportion of that is due to the buzz from the YouTube deal.

    Google didn't buy YouTube to kill it, they bought it because it was a bunch of free eyeballs. Yes, they will have to fund its operating costs (I'd guess at about $3m-$4m a month including that rather large internet bill) but that's pocket change. At minimum, it's a very reasonable experiment for Google to enter into, and it's a way to corner the audience for a whole new media phenomenon. It would have been stupid NOT to buy it.

    Copyrighted content is an issue, but a minor one - the nay-sayers like Mark Cuban are quite frankly jealous. As long as YouTube makes a reasonable effort to take that stuff down, they'll never get taken into court - the copright holders know it's helping their sales, not hurting, they are just making sure they are seen to be protecting their IP so that they can go after real pirates.

    As other posters have observed, piracy and porn isn't the main thrust of YouTube, it's about the network effect of being THE portal for all of those wannabe filmakers out there and then getting the benefit of all the advertising, marketing and distribution around it.

    .... with the real world and the needs of the open source community at large can be seen in the fact that the redline between the second and third drafts of GPLv3 is enormous; more than half the text had to be rewritten, and changes are not something that a purist like Stallman makes readily.

    Don't get me wrong, I'm an open source zealot myself, and I have huge respect for what RMS has done to put open software on the map, and having someone on the extreme acts as a foil for moderates, but the GPL is not a soapbox. Embrace pragmatism!

    Wearing my business hat as CTO of a USA-based internet startup, where naturally we use a ton of open source stuff, my concern is that RMS's extremism is handing a gift to the anti-open-source community, especially to Microsoft in their battle with Linux.

    I deal with venture capitalists and other financial types: their lawyers don't understand open source licensing, and lawyers always fear what they don't understand. Even now, their standard going in position in deal negotiations is "tell us about all the open source your company uses, what the licenses are, and what it would cost to replace it with closed source". The normal GPL gives a business less commercial protection than a proprietary license which, for example, typically inclues indemnification against patent lawsuits.

    We do use GPL'ed stuff, but as a business person I prefer almost any other major open source license (Apache, BSD, Artistic, etc.)

    If RMS has his way, there is going to be massive confusion between GPLv2 (just liveable with, if you're careful) and GPLv3 (totally unsuitable for business use) and the FUD is going to be used against every open source project out there. He's going to force me off of Linux and onto a closed OS. How does that help open source?

    RMS needs to step up to his natural leadership position as elder statesman of the open source movement: this is a political role, which means embracing compromise.

    He also needs to get over the Linux / HURD thing and move on ... 9 years later and half the front page at fsf.org is still an anti-Linux rant. Not helpful.
