London Stock Exchange Price Errors 'Emerged At Linux Launch' 168
DMandPenfold writes "Within the first 20 seconds of the London Stock Exchange's new matching engine going live on Monday, price data vendors began displaying incorrect prices, blank prices and wrong trading volumes, according to Computerworld UK sources. Thomson Reuters, Interactive Data and Netbuilder are among the largest data vendors, providing share prices to traders, that have been displaying pricing problems on some stocks throughout the week. Even the LSE's own data vendor, ProQuote, experienced problems. Concerns are being raised that there could be mistakenly setup connections or incorrect software interfaces at some of the large data vendors. Alternatively, there may be a data caching issue at the LSE that means data going out is not properly synchronised between different systems."

The amusing part of this troll is that it would be modded up to 5, instantly, if it were attacking Windows. The day when I see a pro-linux comment modded "troll" is the day that I take anything posted on Slashdot seriously. Until then, it's just self-important, self-congratulatory, mindless groupthink.

Surely they would have run test data before letting it go live. Maybe even feed it the actual data and simply not publish its results.

"Dang. If only we had read Tubal-Cain's post before going live. Who would have thought to run test data through this darn thing?"

When Apple released a phone they hadn't tested and it turned out "holding it a certain way" prevented calls, it suddenly changed to "holding it wrong", thus blaming the user. No scope for that here?
The offending code (Score:2, Funny)
The offending code was traced back to :
$stockprice = power( 2, rand()*10 + 0.0001 );
Data vendors quickly addressed the issue by cutting the LSE out entirely, and rolling their own rand() function.
Fucking stock markets... .what a joke!
