They just keep coming. Check out my blog at www.sysmod.com/best-practice for stories like:
a) NYSE fines a Grand Rapids stock trader almost a half a million dollars for not documenting share trades. His documentation was a spreadsheet which was "thrown away after the transactions and other documentation were completed".
b) Fannie Mae made a $1.2 billion mistake.
According to their press release, "There were honest mistakes made in a spreadsheet used in the implementation of a new accounting standard". Shortly after Fannie Mae released its third-quarter earnings statement Wednesday 29 Oct, shares started trading down. But Fannie Mae stock regained some of the losses after the company announced the correction would only impact its balance sheet and have no affect on its income statement, news sources said.
c) Spreadsheet variance and Ethical problem at MCI
Watchdog Calls for Further Investigation of MCI
Oct. 10, 2003 Telecommunications News PRNEWSWIRE
The August 2003 Department of Defense IG has identified MCI over-billing in "Financial Management - Certification of a DOD Payment for Telecommunications Services." This report states, "... many of the invoice amounts listed on the MCIWorldCom spreadsheet were inaccurate. Specifically, 467 invoices on the MCIWorldCom spreadsheet differed from the hard copy invoices by $2.1 million.
Last month, The New York Post reported a former MCI employee's claim about over-billing at the State Department: "It was wrong and I regret it. We were over-billing the government $20,000 a month on one circuit. We had thousands of government circuits -- many of them through the State Department. We were stealing from the government. [The order to overcharge] came down from a vice president and through three layers of management. It would come up in staff meetings all the time and everyone complained about it, but no one in management listened."
The story above leads neatly into this:
This conference organised by The Institute of Chartered Accountants in Ireland will discuss the U.S. business scandals and the lessons that they may hold for corporate governance in general, including Europe, and how the integration of business ethics into the organization itself can help mitigate such problems. Venue: The Guinness Storehouse, St. James’s Gate, Dublin Time: Friday 7th November 2003, 2.00pm to 5.30pm. Information: Tel: (01) 637 7200 email ca at icai dot ie
The ACM, Association for Computing Machinery, has had a Computer
Security Day on 30 November since 1988. More information can be obtained at www.computersecurityday.org . (update 11-11-03)
On 3 November, the Labour Party in Ireland issued a press release urging suspension of the proposed e-voting system "until flaws are addressed".
“The reforms proposed by the Labour Party are as follows:-
1. The introduction of a Voter Verifiable Audit Trail (VVAT) which would create a parallel paper record of votes cast which could be stored and checked in the event of a dispute over an election outcome.
2. The use of Formal Methods to ensure that the software used in both the election machines and in the vote counting is totally reliable.
3. The adoption of formal procedures to prevent interference either with the machines software or counting process.
4. The carrying out of an integrated end-to-end test of the entire system.
5. The establishment of an independent audit and supervisory role over electronic voting for the Standards In Public Office Commission."
The issues were discussed in June 2003 on the Open mail list and the IRISHLAW mail list in Ireland.
The software was audited by PMI software
Their code review is available at
The hardware was audited by KEMA http://www.kema.nl and TNO Building and Construction Research http://www.bouw.tno.nl
Electronic Voting: What You Need To Know by William Rivers Pitt - Oct 21, 2003
"The ideal voting technology would have five attributes: anonymity, scalability, speed, audit and accuracy.
You want anonymity, but you also want audit ability. The problem you have is that those two things cannot really coexist to the fullest extent. The way that we do audit ability is that we track all transactions that happen. "
Dublin 10th –12th December 2003.
I attended James' workshop in Edinburgh. My report is in the June 2003 issue of PraxIS.
James has solid material and a full-flow, no-slack presentation. Be prepared for a lot of work!
His claim to fame is on context-driven testing and heuristics for deriving test strategies and test plans. That works very well in rapidly changing environments, particularly in exploratory testing where testers are given a product they have not seen before. Those in a more corporate environment where the same product is being tested all the time, with small improvements, can use the ideas to brainstorm things to test that they may not have considered before.
I also give a tip in the report on how to star in the course. I don't want to give people an unfair advantage, of course, but it's good!
As a software application developer, I found the course exercised my critical thinking faculties, which is always a good idea for developers, who tend to be write-only people ;-) The course materials have all the usual checklists and idea generation material, some of which I put to use right away, and found them helpful.
More information from Newell and Budge : http://www.newellandbudge.com
I got some feedback from last month's mention of anti-virus software. Daniel Clark of Ryba Macaulay Limited wrote to say that they much prefer NOD32 to Grisoft.
Daniel says "A quicker scanner and has not failed to catch an 'in the wild' virus in 5 years of VB testing... " and supported it with a PDF report from Virus Bulletin.
On the Enterprise Ireland ecommerce mail list, I got an answer to my enquiry last month about internet voice conferencing. Fiach pointed me to www.Skype.com . An article by Robin Good at www.masternewmedia.org Master New Media "Please Skype Me" calls it a disruptive P2P VoIP Technology that allows you to call and talk Free to any Windows PC.
"Skype is based on the same FastTrack P2P network that Kazaa and other file sharing tool utilize. Unlike Yahoo Messenger, Vonage and Free World Dialup, Skype relies on a P2P (peer-to-peer) network, meaning that the voice packets being sent do not go over a centralized server that redistributes them, but are sent directly between users. "
Reports so far indicate it is free of spyware. There will be added chargeable services, but the basic product is free. Updated 11-Nov: I tried it but it is internet telephony, not teleconferencing; in other words, it provides one-to-one voice calls, not multi-way calls. I suspect audioconferencing will be a chargeable feature soon.

While rehearsing recently a conductor remarked..........
"Basses, please sing a B flat, don't just click on a link that might take you to the web site of B flat"
I've never heard quite such an eloquent but futile plea to get basses to sing the right notes!!
P.S. I'm a tenor ;-)
