Sudo (superuser do) is a program in Unix, Linux, and similar operating systems such as Mac OS X that allows users to run programs in the guise of another user (normally in the guise of the system’s superuser). With this definition in mind, the above cartoon should now be so funny that you will find yourself rolling out of the office laughing.
This also just in from the Phony News Network:
Water managers investigating the apparent demise of Lake Okeechobee were stunned to find the lake intact despite reports that the lake had evaporated. They also found a prankster in the water near the monitoring station and and pushing an electronic water level sensor to the bottom of the lake. The enraged water managers then plugged in a toaster and threw it into the lake, killing the prankster. His last words were, “No sense of humor, no sense of humor at all.”
This just in from the Phony News Network:
Lake Okeechobee, once Florida’s largest lake, has completely evaporated due to a deadly combination of the ongoing drought in Florida and the summer heat. Last week its water level had reached just one half of an inch before it evaporated, leaving behind miles of evil-smelling mud with an odor that resonated all over Florida. Water managers are investigating the lake’s demise and are scrambling to come up with ways to replenish Florida’s rapidly depleting water supply. This blog will be updated as this story develops.
I was tuning around my scanner the other night when I picked up an amateur radio broadcast with two ham operators engaged in a friendly chat. One operator had just updated her web site with a section devoted to ham radio and decided to do a plug for it on the air. The web site is called Everything You Can Get, and it has some useful stuff such as sports news, advice from the site’s author and a countdown timer that actively counts down the days until the start of the new school year.
Just down the street from where I work is the Busch Wildlife Sanctuary, where injured and orphaned wildlife are brought in for some tender loving care from the staff there. It’s almost like a zoo with various specimens of wildlife living in luxury in their large, well-furnished cages with plenty of room to roam. It’s the perfect place to take the kids to have a little fun learning about nature and our place in it.
One of my first tasks at work was to create home folders on the server for the users to store their data. This data would then be backed up every night to the server’s tape drive.
My boss had tons of data to move to his new home folder but ran into a problem. His computer was set to use offline synchronization to allow access to his data should the network be down. The files were stored in a cache that was eating up his hard disk space and left him with only 24MB of free space. His computer has a second hard drive that has way more free space available for storing the cache. He wanted me to move the offline file cache to the second drive but Windows has no options for moving the cache there.
I did a quick search online and found a program called Cachemov, which is part of Microsoft’s resource kit, but can be downloaded from all over the web. It’s a very small program but it handled the task of moving the cache very nicely. As a result, my boss now has 37 gigabytes free on his hard disk, which pleased him greatly. That alone made for some serious job security.
I work at a sewer treatment plant where I work in the operations department as a computer coordinator. I will be in charge of maintaining the computer systems there as well as fixing any problems that arise. This promises to be some seriously cool work ahead.
I spent the first few weeks hanging out with the staff and got to see what they do. I even got a grand tour of the plant, which utilizes state-of-the-art equipment to treat the sewage. This equipment is monitored by a computer in the operations building, where operators can monitor everything that goes in in the plant and remotely make adjustments to the machinery to improve their efficiency.
Needless to say, I got to visit the building where the raw sewage enters the plant and it smells absolutely sickening in there. But it’s the start of a fascinating process that eventually strips the water clean and ready for re-use. At the back of the plant are some huge ponds where the recycled water ends up, ready for irrigation into some of the nearby golf courses. It’s so rewarding to work for an establishment that’s helping the environment.
I will post solutions to whatever computer problems I will encounter at work. Hopefully they will help you too, provided that no raw sewage comes pouring out of your computer.
During my scuba trip to the Turks and Caicos Islands some 10 years ago, I got a taste of night diving. It is totally different from day diving. When you dive during the day, you take the sun for granted as it illuminates the reef, preventing you from becoming disoriented. However, at night, it feels like entering a dark void with no respect for your senses. If it weren’t for your trusty compass and your flashlight, you can easily get confused and get separated from your dive group.
The sun was still setting when my dive group boarded the boat, but when it reached the dive site, it was dark. That did enough to set the mood. Just what would be lurking down there?
We all turned on our flashlights and dove in. Once we reached the bottom, the sight of some 12 beams of light moving in random directions was a sight in itself. We all stayed together and explored the nearby reef.
The dive was eerie but fascinating. As I swam close to the reef, I saw some tiny fish lurking near the coral that were attracted to the light. These fish were everywhere, staying close to the coral. I also saw a large grouper, a fish with a reputation for being extremely friendly. However, this particular grouper was anything but friendly. It darted away from me when I touched it.
We continued diving along the darkness, exploring the wall of coral. The only light we had was where the flashlight beams were concentrated, and since there were about 12 of us on this dive, we had adequate lighting to get a sense of the area. I cannot imagine how it would be if there were two people on a night dive, let alone one. I’m glad I didn’t go alone. Going alone is never a good idea anyway.
As the dive progressed on, I got the sensation of being on a hill on a foggy night watching a group of villagers with flashlights pass by. No wonder it is easy to get disoriented during a night dive. Still, I stuck with the dive group as we slowly made our way back to the dive boat.
That was the one and only time so far I’ve tried night diving. It was eerie but a very rewarding experience. I would definitely go again.
Speaking of small programs, you ought to check out the Off By One web browser, quite possibly the smallest web browser ever. It’s only 1MB zipped. It uses your computer’s memory for caching, so it’s also very fast. When you’re done surfing, exit the program and your surfing tracks disappear without a trace.
