  1. Over-The-Counter Derivatives Trades on Schneier Asks Why We Accept Fax Signatures · · Score: 1

    An OTC derivatives trade is usually for some horrendously complicated thing that is so customised, it hasn't a chance of going the listed route. OTC trades are made by phone and they can be made for tens of millions of dollars. The signed trade confirmations go more often than not by fax.

    The check is that I have a timed telephone call and a fax to confirm the transaction and so does my counterparty. Of course that's where the real fun begins as the deal needs rekeying.

    In modern times there is something called FpML and then there are matching/confirmation systems such as SWIFTnet FPML, SwapsWire or DTCC Deriv/SERV which provide electronic signatures and non-repudiation, but they are still not used widely which means ultimately back to the good old fax.

  2. Real-Time is an illusion on Google to Offer Real-Time Stock Quotes · · Score: 1

    I have worked at several exchanges. Prices go out in what is usually known as the broadcast feed.

    The normal method is that when bid and offers come in, they are added to the order book. If this changes the best bid or offer on a product then this is added to the feed. When a deal matches, you get an execution price and that is also added to a feed. In addition, depending on the product and the time interval, you will get something called market depth, i.e., best 5 (or whatever) bid and asks.

    This is a lot of data but it is buffered. Usually the system will wait until the buffer is full before dispatching the data, or until the holdback timer expires (usually around a second or so). If you look at something qith high liquidity, you can be more or less guaranteed that the best bid or offer (top of the book) has already gone and you must look deeper.

    The thing is that often the price you see is not the most recent price. Even if you are paying $$$$$ for proximity services (you pay to be on the same LAN as the exchange, which is what the Algorithmic traders do).

    When you are outside you need to use depth information as well as current best bid and offer and price history to predict where the price is going to be by the time that your order reaches the market.

    Not really. There are other document management systems around - even free ones.

    Its ok, just be a cleaner instead.

    It appears that the checks on cleaning staff are minimal (spot checks) with access both airside and sometime to the aircraft. The pay is crap and there is a huge turnover so nobody is willing to check the staff properly. They end up often with guest passes or 'john-doe' passes (reused passes of colleagues who have quit).

    Unfortunately, it is extremely difficult to challenge these people. They have been given so many powers from the 'War on drugs', the 'War on terror' and now the 'War on piracy' which seems to have been linked by the **AA with drugs and terrorism. Can you suggest anyway around this?

    It is a real problem and is costing the US real money. Put it this way, the Visa system to enter the US is now positively visitor hostile compared with most other countries. You now face unreasonable search by customs so needing to clean a laptop before entering. Even then you face extra time while your HD is scanned. Let alone, your MP3 player or whatever.

    So, if you are, say a Malaysian businessman wanting to find a new business partner, due you choose the US or do you go somewhere else?

    United had some of their economy seats spaced out more for better leg room for a while, but I never saw anything about which flights had that and which didn't.
    This is usually called premium economy and many airlines have it for long-haul. The seats are as you say better and a bit more legroom.

    Yep, the field drops off but it is much larger than anything you normally experience from the earth and the thing works at R/F so it will induce small eddy currents. Maybe none of this is very much (if it did, then nearby medical equipment may have problems) but it may provide sufficient cues.

  15. Re:How does this make sense? on French Judge Orders Refund For Pre-Installed XP · · Score: 1

    I believe the OEM agreement was to prevent people from taking a licensed OS from one system to another. Actually if you buy a non-OEM edition of the OS, it is very difficult for a vendor to stop you moving it to a new system and wiping the copy on the old system before sale. Many people used to forget that last part!

    After a lot of going back and forth the wording on the OEM agreement had to be adjusted to "not ship without OS". Some vendors ship with FreeDOS to get around that (and also diagnostics to be run).

    Teaching English as a foreign language in some far of part of the world doesn't pay that well but it is open to almost any graduate (a TOEFL type qualification is seen as a luxury rather than a requirement in many countries) and although many do it, the life is best suited to the younger person with no ties. Essentially you get board plus some minimal salary.

    Good point. I have seen the computing exhibition at the Science Museum and it is rubbish (apart from the difference engine). Apart from the crypto stuff, a large part of the history of British computing is represented there.

    Yes, and the guy in the last picture is Tony Sale a former technical officer at MI5 who was given access to former BP Staff for the reconstruction. Essentially as the machines were broken up at the end of the war, he had to work from scraps of notes and very distant memories. He is fascinating to hear.

    The only issue is the place is not so easy to get to, either a journey up the M1 or fun with the wonderful British public transport system.

    Yes, in theory the Imperial War Museum could take on the crypto and the Science Museum could take on the computing. Unfortunately, neither have space, and frankly I was quite disappointed by the Science Museum where there are few good new exhibits.

    The story came out in the mid seventies. There is a reason for it which you see at the exhibition. Some Soviet devices were based loosely on technology from the Lorenz devices and they were being used through to 79 in Warsaw Pact countries.

    Bletchley was picked because the Brits thought it more likely that code breaking would stay secret longer if done in some old civilian houses instead of military facilities.
    Yes, they wanted out of town but many former manor houses were acquired by the government over the years and turned into research laboratories. Many of these laboratories have been privatised now, but although pay for British scientists working in pure research is crap, they sometimes have some beautiful locations to work in.

    I'm not entirely sure about that - the GEC System 4 was originally a telco switch control computer. The ICL 19xx series were commercial/scientific data processing systems. The 19xx series were apparently a development inherited from Ferranti in Canada. There was a paged operating system available (George-4) but it wasn't a real virtual machine system whereas the 29xx series ran VME/B and VME/K and was properly implementing Virtual Memory. The 29xx had almost nothing in common with the LEOs, so I think the nickname was more an alusion to history.

    Zeppelin NTs have been flying for ages now over various bits of Europe. Saw one over Frankfurt about eight years ago, they were running short sightseeing flights (sorry linked article is in German) from a field just outside a nearby town (which had historically been used as a Zeppelin airfield). There are some videos if you are interested in seeing more. One should be flying in the Munich area in 2009 (there was some hope to get it for Oktoberfest this year, but it didn't work out).

    The article isn't quite accurate, Airship Ventures is only ordering. Construction is taking place down at Friedrichshafen where the original Zeppelins were built.
