Comment I find my CS staff never use math... (Score 1) 583

...however they use logic a great deal.

Keep in mind when old-timers like me were in college, CS was about determining how to best utilize the 640 KB of memory you had available. You needed to understand more math than now.

OTOH, I actually think that multiple languages are a must for programmers these days. I - for one - speak/write German and Spanish. I have seven programmers with CS degrees and an additional six analysts with CIS degrees working for me.

Exactly my point. I always chuckle when I read of some "environmentalist" claiming a superior-than-thou attitude when discussing driving their Prius. (Which - not only is made with ultra-toxic non-renewable chemicals but is produced using almost slave labor. (Here's one of many examples: http://piggington.com/ot_the_darker_side_of_toyota_human_trafficing)

And you can make diesel out of pretty much anything - used veggie oil, soybeans, dead dinosaurs, coal. All those things are FAR less polluting and dangerous than the chemicals used for batteries.

I have a solar system on my house: http://enlighten.enphaseenergy.com/public/systems/EJpk11639

That at least is a beneficial process unlike the supposedly "green" hybrid cars.

Exactly.

12 * 225w panels = ~ 2700 watts theoretical maximum per hour. You figure a 20-40% loss in converting from DC to AC and also because teh panels are not all titled the same way.

2700 watts * 6 hours of immolation = 16.2 kWh. (http://rredc.nrel.gov/solar/calculators/PVWATTS/version1/)

As of this moment - 1:00 PM - I'm generating 2160 watts.

Okay, so basically it sounds like the programmers did a poor job of implementing state.

Whenever I've done an application (which I don't anymore being a PHB) I always forced closed a session on either logout or browser disconnect. (You never know when that BSOD might hit for those using windows.)

Ah, well, I guess my 75-year-old father-in-law is right in that he refuses to do online banking and insists on going into the branch for every single transaction. :P

AFAIK, session hijacking has been an issue since - well - since Al Gore invented the intraweb.

No matter what browser you're using - unless it is Lynx - you probably can be involved in a session hijack issue. UNLESS you forcibly close that session by closing your browser.

I saw a post about using Wintendo. I don't think that Windows or Linux or OSX are any more or less vunerable. Just the fact that people don't forcibly close sessions.

Now, where did I put that copy of Firesheep?
