I just downloaded the Fedora 11 DVD installer using utorrent on Windows XP. After completing the download, I downloaded sha1sum.exe from the gnupg list and checked the DVD image’s SHA1SUM – it returned
which is nowhere near
which is the string listed with Fedora-11-i386-CHECKSUM (came with the torrent download).
It turned out that the second hash string is for SHA-256 and I only need md5deep to check that everything is indeed in order. *wipes forehead*
Just read something really cool from sysadminday.com:
A sysadmin unpacked the server for this website from its box, installed an operating system, patched it for security, made sure the power and air conditioning was working in the server room, monitored it for stability, set up the software, and kept backups in case anything went wrong. All to serve this webpage.
A sysadmin installed the routers, laid the cables, configured the networks, set up the firewalls, and watched and guided the traffic for each hop of the network that runs over copper, fiber optic glass, and even the air itself to bring the Internet to your computer. All to make sure the webpage found its way from the server to your computer.
A sysadmin makes sure your network connection is safe, secure, open, and working. A sysadmin makes sure your computer is working in a healthy way on a healthy network. A sysadmin takes backups to guard against disaster both human and otherwise, holds the gates against security threats and crackers, and keeps the printers going no matter how many copies of the tax code someone from Accounting prints out.
A sysadmin worries about spam, viruses, spyware, but also power outages, fires and floods.
When the email server goes down at 2 AM on a Sunday, your sysadmin is paged, wakes up, and goes to work.
A sysadmin is a professional, who plans, worries, hacks, fixes, pushes, advocates, protects and creates good computer networks, to get you your data, to help you do work — to bring the potential of computing ever closer to reality.
So if you can read this, thank your sysadmin — and know he or she is only one of dozens or possibly hundreds whose work brings you the email from your aunt on the West Coast, the instant message from your son at college, the free phone call from the friend in Australia, and this webpage.
My uncle was supposed to buy a relatively cheap but decent enough home computer system. Here’s what I should have given him.
Short explanation on my choices:
- Processor – good enough starting chip; not too expensive but good enough to handle usual load
- Motherboard – good board with plenty of upgrade opportunities; i’m thinking of upgrading to a quad-core if budget permits
- Memory – i sort of splurged on this one; haven’t really tried a corsair xms but i like the extra it placed aesthetics
- Video card – good enough budget VC;
- Optical drive – i just picked the one on the top of the pricelist; they’re pretty inexpensive nowadays
- Hard Drive – i have a lot of hard disks lying around (250GB, 320GB, 500GB,..) so I just picked a starter disk
- Power Supply – really needed to replace the stock power supply that usually comes with the casing
- Case/Keyboard/Mouse – cases are usually store options; Logitech Internet Pro for keyboard and mouse
- LCD Monitor – this was supposed to be samsung but i’m not really a fan of beveled LCDs
- UPS – there have been a lot of power interruptions lately so better be safe than sorry
