At least it is another tool to consider. Almost always I do not slurp in the file but rather read it a line at a time to determine what to do with that line (e.g., transform it; extract information from it; ignore it). mmap would be a good replacement for slurp if such a need arises. Although I suppose I should try it as a replacement for the normal open. Doesn't seem like it would make any difference though. -- Rick From westerman at purdue.edu Mon Feb 15 17:30:38 2010 From: westerman at purdue.edu (Rick Westerman) Date: Mon, 15 Feb 2010 20:30:38 -0500 Subject: [Purdue-pm] Conflict with WIFi security Message-ID: <69F91249-D2BE-4E62-B929-52E5D0C5618B@purdue.edu> Of course Perl doesn't have much to do with WiFi security ... but our meeting Tomorrow (Feb. 16th) has a conflict with the following. So we might expect a few less people. Or maybe since the WIFi talk continues after 1:00 post-lunch (and probably really does not start until then) people who are interested in it can come to PM and then leave for WiFi. ------------- Just a reminder that we have Bob Morrow coming tomorrow to talk about Wi-Fi Security from noon to 2:30. Wi-Fi (IEEE 802.11) is by far the most common wireless computer network, and the relentless tide of sophisticated attacks make security of this system critically important. Dr Bob Morrow will address several Wi-Fi security threats, including disclosure, data integrity, and denial-of-service attacks that can bring a network to its knees. Simple propagation analysis can determine a target network's vulnerability to eavesdropping and jamming. The weaknesses of wired equivalent privacy (WEP) are legendary, and Bob will discuss how these are addressed through the IEEE 802.11i standard with improved authentication, key distribution, and encryption. methods. Finally, he will provide a summary of simple ways that wireless security can be improved beyond simply implementing 802.11i. Come bring a lunch, here what this expert in security has to share. It will be held in STEWART 310. ---------- -- Rick -------------- next part -------------- An HTML attachment was scrubbed...
