  • Wolfe, Gene. The Fifth Head of Cerberus. New York: Ace Books, June 1976. ISBN: 0312890206 (evanjones.ca)
    Bray this classic Sci Fi novel I found it somewhat confusing at first but still intriguing and obviously filled with things that I missed I flew through it in about a week so I guess that means I liked it

  • tranSticks: Media Virtually Connected beyond Space (evanjones.ca)
    using physical tokens to create a virtual connection between devices They can then be reconfigured in the same way wired devices would be I like this concept because it provides a simple way to associate physical things with virtual resources and it provides a very understandable security model It also means that there are physical things involved with all the disadvantages that has Another complaint is that for added security

    particular wall jack and to return the coordinates for that jack For wireless the base station could return its own coordinates and indicate that the information is only accurate to within 200m or whatever the range is If necissary the client could use wireless triangulation with multiple base stations to improve that accuracy The RFC notes that this is critical to enable emergency services such as 911 for VoIP but

  • Basic 802.11 Statistics (evanjones.ca)
    each of these data rates can actually deliver between two nodes when sending data at a constant rate This throughput is the network layer throughput meaning the throughput if you strip out the MAC header but include the IP headers As you can see each data rate tops out at a little bit below the actual data rate This difference becomes more pronounced as the data rate increases At 1 Mbps 802 11 delivers 91 7 of its data rate while at 11 Mbps it delivers only 55 4 However this test was performed with the standard long preamble Some modern cards can use a shorter preamble which is about half the length This makes for a slight improvement 483 kbps at 11 Mbps I repeated this experiment with TCP Sack The maximum data rates are listed in the table below The TCP throughput is for the delivered bytes at the network layer It includes the IP and TCP headers but excludes retransmissions As expected TCP achieves a reasonable data rate but still falls short of the optimal values 802 11b Maximum Throughput Versus Data Rate Data Rate CBR Throughput Mbps Data Rate TCP Throughput Mbps Data Rate 1 Mbps 0 917 91 7 0 790 79 0 2 Mbps 1 722 86 1 1 442 72 1 5 5 Mbps 3 897 70 9 3 014 54 8 11 Mbps 6 099 55 5 4 276 38 9 11 Mbps short preamble 6 582 59 8 4 903 44 6 Multihop Throughput Things start to get more interesting when you relay data over multiple hops When you go over two hops the ideal throughput is halved since the node in the middle must accept and retransmit the data While it is doing so the sender cannot transmit The next

  • Practical Versus Theoretical (evanjones.ca)
    never had a class on how to recognize buffer overruns in their code or how to write secure code Is this true Amazing given the focus in the industry lately Yes Robert it is true Even in security courses you will rarely find an in depth discussion of what a buffer overrun looks like Or an integer overflow Or other common vulnerabilities So are the universities failing to teach the correct material Maybe The issue is that the universities do not teach the practical aspects of writing software They teach the theoretical aspects of writing software That is the reason it is called computer science and not computer programming In some senses this is ridiculous It produces graduates who understand how systems work from a high level but may not have a good grasp of how it is actually built However it also produces graduates who can learn and adapt easily to changes in technology because they understand the fundamentals There is a need in this world for both types of people those who are good with the nuts and bolts and those who understand the systems as a whole That said I think there is a lot of room
