  1. Re:3.757 ms on Somebody Stole 7 Milliseconds From the Federal Reserve · · Score: 1

    Switches, routers, processing time by the trading software to come to a decision; all will add delay.

    It was not worth to invest a few milions in custom (quite unlike typical) hardware and software?

  2. radio transmission delay = 3.2 ms on Somebody Stole 7 Milliseconds From the Federal Reserve · · Score: 1

    Radio transmission delay is 3.2 ms. It required transmission of a few bytes (single data bit with "huge" security overhead).

    956 km / 300 km/ms = 3.2 ms

  3. Re:Wrong Question on Ask Slashdot: Recommendations For Non-US Based Email Providers? · · Score: 1

    User2user encryption is important but it is not all. Some people may dislike idea NSA.gov(.us) registering even "communication patterns" (when, to whom, size). User2user encryption does not cover it.

    "Communication patterns" with big supporting databases can "suggests" A LOT.

    P.S. There would be no american revolution with NSA.gov.uk watching carefully ;-)

  4. Down with "local email monopoly" on Uniwersities! on Choosing a Replacement Email System For a University? · · Score: 1

    By my standards you ask WRONG question. The way you "crafted" the question severely limits "solution space". Do you want simply choose new local email monopoly? Anything worth truly to be called a University should choose "main email system" in "heterogeneous mix for ever". It makes supports for public standards crucial. If you want to be "locked in" then you do deserve the consequences.

  5. Poxies? on Satellite Internet Providers · · Score: 1

    Do you use per key services proxies?

    High latency is "deadly" in combination with non negligible packet loss.

    P.S. had used ISP offering via two sat links connection to most of the Internet "a few+ years ago".

  6. What has been left to hide? on AT&T Says Spying Is Too Secret For Courts · · Score: 1

    The most obvious suspicions is that full extent of mass invasion on privacy has not been revealed so far. Irony: Trust your telco to protect you from info harmful to feds ;-)

  7. Military inteligence is a contradiction in terms on Google Earth and "Collateral Damage" · · Score: 1

    Google-maps satelite images are "second fresh". Any military force seriously complaing about damages caused by "second fresh" images risk being accused of being commanded by lazy irresponsible idiots or by "imagination less" commanders.

    BTW Any change of policy by google will not "take away" images already colleted by "the other side".

    Incopetence does kill.

    Military intelligence is a contradiction in terms.

  8. Way to 1984 surveillance (?) on Cameras Help Cops Catch a Killer · · Score: 1

    Could "the party" in 1984 book achieve full control without full surveillance?

    If you think that full surveillance will never be missused or that it will not create strong temptation to be abused then you are unfit to live in the world of "before voting day promices".

    Are you brave enough to state that only communism is capable to surveillance abuses?

  9. Re:I have a problem on Cameras Help Cops Catch a Killer · · Score: 1

    I have read the book. If you stubornly insist I can read it once more. Have YOU read it?

    You assumption is wrong even if my interpretation of the book is not the only sensible one.

    Good police does not too much wrong things. If you belive you it deserves unlimited trust then history have taught you nothing and you must be blind and deaf.

    You own goverment is always in the best position to take away your freedoms. Unlimited trust does not pay. For me mass deployment of CCTV crosses the reasonable trust line.

  10. Re:I have a problem on Cameras Help Cops Catch a Killer · · Score: 1

    Asking public leaves traces. With public cameras everywhere you can be 100% sure the footages has been also used in cases police would not like to reveal for bad reasons.

    Are you an idiot beliving that police can not nothing wrong?

    If you want to get support for mass deployment of CCTV cameras then talk about privacy safeguard before deployment.

  11. Create a well regulated militia *TODAY* :-) on Second Amendment Questioned · · Score: 1

    IMHO they promote and encourage *mass* creation ASAP of "well regulated militias" in USA.

    Are they *crazy*?!

  12. Bombe on Enigma-Cracking Bombe Recreated · · Score: 1
  13. Only some earthquakes produce tsunamis on P2P Hard Disk System Warns of Tsunamis · · Score: 1

    Tsunami detection systems have no problems whatsoever with detecting eartquakes/big eartquakes. The tricky part is determining which earthquakes produce dangerous tsunami wave.

    In some place sea bed/shore line may magnify tsunami coming from specific directions, it complicates things even more for predicting very local tsunamis.

    There have been false tsunami warnings on the record when big eartquakes have "failed" to produce predicted tsunamis.

  14. Cost of "one day breaker" system on RSA-640 Factored · · Score: 2, Interesting

    Has anyone publish (theoretical) costs of system capable to break given RSA lenght in one day based on the known systems?

  15. There are many ways to make spammers pay on In (Sort Of) Defense of Spammers · · Score: 1

    Another option is to make it simple for people who "manually" check if "tagged as spam" e-mail is real spam to report it to spamcop.net (or similar) service and make the service report the compalint to the relevant abuse address. It can be as simple as copying from one imap folder to another. Let's make ISP hosting spammers and spammers themselves face hundreds of complaints per day, let's blacklist ISP who reject valid spam complaints with no valid reason. Complaints processing costs money, ingoring complaints can costs being out of business :-) anfi
