The + means you can pay more depending on the support configuration.

It doesn't make a difference whether the burglar came into your house through an unlocked window or an unlocked door. If, assuming you are correct that Linux has a lot of vulnerabilities due to misconfiguration, then isn't it time to review the configuration process?
Actually, it is *past* time to review these sorts of things. While the Linux kernel and a few key apps -- Apache, for example -- get heavy review, there are tons of popular Perl and PHP that needs to be scrutinized. Also, default security checks for things like MySQL, Postfix, Sendmail and BIND need to be available and easy to use.
Because the majority of problems with Windows stemmed from system-level vulnerabilities and problems. Linux, however, seems to suffer more from application level vulns (SQL injection, misconfigured or sloppy PHP.
In short, with Linux, most vulns are due to misconfiguration of apps and NOT an inherent flaw in the system.
Windows has, so far, had a bad track record of SYSTEM LEVEL flaws and not necessarily inherent flaws.
You mean people aren't holding their breath waiting for DNF to get released? The YEARS of delays have damaged the possibility of sales? Gasp! Say it isn't so!
See, I know that to be true, but I can tell no perceptible difference in my wired T1 at the office, and a wireless 1.54/512 that I use also. What the eye doesn't see, I don't miss. Or whatever.;)
True. However, I just moved my home network OFF wireless to gigabit wired, simply because I move a lot of large files around locally and the wireless was killing me. I still have a WAP, mainly for the X-Box with the wireless adaptor and when friends come over with laptops.
My new job has a DS-3 (10 Mbit) at the office. I would notice the wireless degredation.:-)
(waits for the inevitable semi-technical disinformation er, um, example)
Okay, I hope you didn't have to wait too long...
1. The 2.4 GHz band is crowded and going to get more so. What happens when half your neighbors have cordless phones in the 2.4 GHz band? Or worse, half of them have their OWN 802.11 b/g home networks, all competing for frequency and bandwidth with both yours and the ISP?
Yeah, I know... 5 GHz, etc. Rinse, repeat.
Available bandwidth/bitrate on wired connections is many times that of wireless. The only thing wireless has going for it is convenience. Granted, that is a big plus.
As far as security goes...once you authenticate to the ISP's network, usually via SSL/TLS, everything else is then sent in the clear. Most people are still clueless and don't bother with SSL-encrypted mail.
In short, wired connections do provide a bit more security for the clueless masses whereas wireless takes that curtain away. That MIGHT be a good thing, making people PAY ATTENTION to security. However, I'm not going to hold my breath.
If it is to the Internet, then you're out of luck. 99% of anywhere you go couldn't come close to filling it.
Between remote offices? That is much better. It allows for things like multi-camera video conferencing or multiple simultaneous conferencing sessions.
It also lends itself to "location transparency" demos -- where it doesn't matter where in your system the resouce is, it acts like it is right at your fingertips.
For example, realtime video/audio editing of multiple tracks while the raw data is stored on a SAN in one building and the editing horsepower is in a different building -- and you're in a third just piping the interface.
Large scale CAD/Design reviews, with people being able to mark up and manipulate 3D imagery in real time, regardless of where on your net they're at.
Your big problem is going to be device latency. Spinning drives up, delays in software starting, etc. is going to be much more noticable. Bandwidth like that is great once the bits start flowing, but getting it started and keeping it filled will be taxing.
Unless you do testing that generates obscene amounts of data -- like collecting data from a supercollider, etc.
Doesnt' the 1750 use a PERC3 controller if you configure RAID-5?
What problems have you been having with the 2650? We've installed Debian Stable on more than a few 2650s, 1650s and now 1750s and haven't really had any issues.
Again, Jurassic Park effects were done with big iron... not with a consumer-level computer with a single 680x0 processor and an NTSC/PAL video board.
True, however the effects for Babylon 5, Sliders, SeaQuest DSV, Star Trek Voyager, etc. *were* created and rendered on consumer-level computers with a single 680x0 processor. No NTSC/PAL video board, though, other than for dailies. Lightwave rendered this stuff out using ScreamerNet, a cluster rendering tool over a "renderfarm" of Amiga computers. This was all before there was a PC version of Lightwave.
...they saw someone looking at porn, or one parent to see it for themselves.
How about positioning the monitors where people other than the user can't see them? I can't find the link, but remember reading about Cyber Cafes in China.
To be legal, the screens have to be turned in, where everyone can see what you're doing. The *popular* places take their chances and turn all the monitors towards the wall, with little cardboard slats on the side creating a private environment.
And, just for curiosity, how do you do the remote viewing? Software or hardware? (I.E. -- a KVM hooked to all monitors or something like VNC or NetMeeting?)
All the issues with the early 2.4 kernels were taken to heart and ended up spawing projects like the Linux Stability Project (http://www.osdl.org/projects/26lnxstblztn/results/).
Because of all this attention, 2.6-pre were quite a bit more stable than the 2.4-pre ever was.
The amount I study isn't directly related to UoP vs, say, Washington State Univ. I looked at the courses, and the subject material was very similar. I wouldn't have to study for 90% of the material at either place -- other than reading through it once.
I obtained an A.A. degree from a local community college many years ago. I am just finishing up my last two years of credits.
In both cases, UoP and WSU, I had many years experience in the core courses needed for my BSCS or BSIT. I've *taught* many of them to engineers at Fortune 500 companies. The only reason I didn't CLEP (test) out of most of them is because of school policy -- you can only CLEP so many credits. Junior and Senior level courses in programming, database administration and LAN/WAN management aren't going to do me a lot of good. Yes, I would learn some stuff, but not enough and probably nothing I'd remember after not using it once class is done.
The *main* reason I took UoP over a "traditional" school is time. UoP, I can do 90% of it online (and it takes about 2 hours a day, 5 days a week). With a family and full time job, there wasn't any other University that I looked at that I could have actually finished. They didn't offer the needed credits via night/weekend or telecommute classes.
I would like to continue with an advanced degree at a later date (when I have the time), and UoP *IS* accredited and acceptable at "traditional" schools.
As far as comparing notes and studying in as much depth as you. In my field (computer networking & network security) I've probably gone a hell of a lot more in depth than you have -- just not in a classroom. Have you ever had to analyze network management traffic on a global ATM/Frame Relay network? Ever had to take 10 Gb of raw DSL provisioning logs, spanning a full week of traffic, and reverse-engineer them to figure out why 10% of all provisions failed -- after the team that wrote it was laid off and replaced with a new team in India who wasn't yet up to speed on the code. How about then taking that data and creating a modeling and reporting tool for near realtime analysis of future DSL provisioning traffic? Analysis of multi-gigabyte database performance on an 8-way 64-bit system? Creating a model for properly scaling such a database to terabyte+ size on a 24-way 64-bit system?
I've never had a class at UoP that taught to the test. And I *don't* bitch about underqualified CS students out there. I know damn well how hard it is to get real-world experience. I bitch about people who think a degree is a REPLACEMENT for experience as opposed as a supplement to it.
Don't blindly knock UoP. Like any school, you get out what you put in.
After being unemployed for the last 6 months, I found my resume rejected by automated screening processes because I didn't have a B.S.
The bot didn't care that I had 10+ years of hands on experience in exactly what they were looking for.
Those few that DIDN'T auto-reject, I got in for interviews and have since gotten an excellent, good-paying job with one of them.
I've known too many people with traditional degrees from traditional universities who were worthless at their job to use a degree as a BS degree as a major benchmark for employment.
Graduate degrees are usually a different matter, though. (Except MBAs, for which there are more diploma mills than any other degree.)
The University of Phoenix's online classes only require 1 physical book for the entire duration of your study with them. The rest are made available online in PDF, txt or HTML format.
Tuition also includes access to a decent online library of periodicals, journals, newspapers, books and other research material.
It eliminates both the cost of books (tuition is no higher than traditional schools w/physical books) as well as the need to lug them around.
If this Chinese gov't attempts to block access to IP addresses that run web proxies outside their control. I can report my own servers to China, so their Big Red Firewall can block all the spam I get from inside China!
to me, it says that a lot of mid-sized sites got burned with red hat's recent killing of rh9. when the option is either a) pony up $400 or b) move to this untested hobby distro (fedora) that requires a complete re-install anyway, people start looking at other distros.
Upgrades are half price -- $174.50 for ES, which isn't that bad if you need the support and RHN.
Or go look at Progeny, who is not only providing "transition" support for RH 7, 8 & 9 users but was also just awarded LSB certification.
A friend of mine live just out of reach from cable-modem/DSL. He's five miles away from my house (cable modem).
In the last month, he's spent more time connecting to my wireless net or going to Starbucks for T-Mobile's wireless net, than at home.
The melting snow is a bitch on the connection (Spokane, WA).
SSH is painful for any interactive work. Latency is a pain and games are shot. Bandwidth caps mean you aren't going to be grabbing 3-disk.iso sets very often.
While it can take a bit to disrupt the DOWNWARD signal, it is much easier to screw your UPLINK signal to the point it doesn't work. Thus, TV is less affected than internet connections.
However, if you have no other option, it beats dialup. It depends, though. Are you far enough out that the phone lines are crap and you are getting 14.4-28.8 dial in? Or are you just in a good area but without DSL/cable?
If the latter, look for an ISP that will allow you to bond two dialup links. Get two phone lines and two modems and get them to bond into one link. Also check out ISDN, though it may be expensive.
