does anyone here have pointers or access to courseware that could be used to teach centos (5.4, i believe)? publicly-available, free C/W would, of course, be ideal, but if you have some decent training manuals that you're willing to license on a per-manual basis, i'm still willing to chat. rday -- ===========================================...

as i'm reviewing the courseware for the rhel (centos) course i'm teaching next week, i'm going to ask the occasional question, possibly technical, possibly more policy. first one involves the choice for virtualization. the course has a short section involving virt using xen but everything i've read suggests that...

..., it always struck me that the training room is the *ideal* place for students to experiment with things they're too nervous or unsure of to try back at the office. this is typically why, when i'm teaching, i save friday afternoon for trying things that are typically not covered by standard courseware. so as long as one delivers the proper caution, i see no problem with something like, "ok, you might never have to do this at your site, but just in case you ever need to upgrade your kernel, let's try it and see what happens." so if the need ever arises, at least they can say the...

I am designing an application to run a fishing tournament I am hosting. Each fish entered will be given a point total based on the length of the fish and the species of fish. Each species has a point multiplier. For Example Trout have a multiplier of 10 so a 20 inch Trout would have a score of 200. My conundrum is in where and when do I calculate the points. The options I have come up

i'm prepping to teach a 5-day intro class in linux starting in about 3 hours, and the courseware is clearly designed around RHEL (apparently 5.1). but since i'm not being provided with RHEL DVDs, i'm just going to hand everyone a centos 5.4 DVD and take it from there. as part of the intro, i want to briefly discuss the varieties of linux related to RHEL, so obviously i want to men...

prepping to teach a 5-day CompTIA linux+ course next week with CompTIA-supplied courseware and, given that it was my choice, i chose to set up the classroom with centos 7.4 on all the student systems since i assume most students are there to learn sysadmin and that's the most likely platform they'll have when they get back to work. also, most students are taking this course to p...

Today we finally opened the doors to "Street Easy" (http:// www.streeteasy.com/), a Real Estate Research Site for New York City. It was built by two guys in three months. It doesn''t have tags, but it has google maps. It rides two bubbles at the same time. It''s like road kill: the price tags will shock you, but you won''t be able to stop browsing around.

I''m new to Ruby and RoR but excited to learn what I can do with RoR; I have Pickaxe second edition and want to get "Agile Web Development with Rails" but I''m aware that the book was published some while before RoR version 1.0 was released. Has a lot changed since then, and would I therefore be advised to wait for a second edition of AWDwR? Many thanks in advance
