VMware Virtual Appliance Challenge   by Anthony Lawrence
- VMPlayer challenge - win money for creative ideas for virtual appliances. VMware is out for blood!
Charging for email   by Anthony Lawrence
- Yahoo and AOL have the courage to start charging for mail: Yahoo and AOL plan to introduce a paid service that lets mass mailers skip their spam filters and go right to the users mailbox. While a lot of people are up in arms about this, I think we all know that something has to be done about junk mail. I think there are adjustments that will need to be made (AOL has already said that they'll waive the fee for non-profits, for example) and the pricing might need some creativity (a flat rate option could be helpful), but I think the basic concept is good.
Reuse or write new?   by Anthony Lawrence
- Sometimes it's better just to start fresh rather than reuse older code - too much time spent understanding!
The World Is Flat   by Anthony Lawrence
- This is a book about computers. The author thinks it's about outsourcing, globalization and all that and of course it is, but the underlying force that drives all of this is computers and the Internet. You know that: maybe you are a "victim" of outsourcing and globalization yourself, or you know someone who is. You aren't going to find much commiseration here: reality bites, and the reality is that the world is changing.
Right back at you   by Anthony Lawrence
- I'm not willing to add links to some random pile of spammish junk that has nothing to do with anything we ever talk about here.
SCO OpenServer 5.0 root can print to local prtr users can't  by anonymous
- Only root can print: I have a Lexmark printer on /dev/lp0, entry in printcap seems fine. root is the only account that can successfully perform an lp to this printer and have it print. Other users can cat > /dev/lp0 and have it print to that printer, just can't get jobs to it through lp.
Broadcom 5700 Gigabit Ethernet on RedHat EL4   by Anthony Lawrence
- I found the network configuration tool was up and running showing an un-activated 3COM 3c59x card. That didn't make sense: I wasn't sure what was in here yet, but I was quite sure it was a Gigabit card. But that's what you'll get if RedHat doesn't find any card: the network setup just shows the first network module it finds. Silly, really: they should probably put a dummy "0.o" module that would show up as "We can't find a card" if it's so much trouble to fix that setup tool.
Apache Spammers   by Sojish Krishnan
- You are being contacted because NOC has received complaints concerning unsolicited emails originating from an IP address assigned to you.
Lady and the Scamp (SCO does the Web)   by Anthony Lawrence
- If you visit SCO's website (yeah, I know, why would you?) soon enough, you may see SCO's new Scamp logo: an evil looking bulldog grinning at you across folded arms. I say "may see" because I really expect that some marketing person is going to get fired over that one and that it will soon be gone, so enjoy it while you can. The "Scamp" name was probably inevitable (Sco, Apache, MySQL and PHP/Perl). SCAMP against LAMP! Those rascals! Don't you just want to hug 'em?
Cheaters   by Anthony Lawrence
- On line cheating: It is an unfortunate fact of life that people will cheat at games and contests.
loss of data while ftp using NET::FTP in perl.  by prapanna
- I have a simple script which does login, cwd and get - for a tar.gz file. But if file size goes beyond some limit, the resulting file seems to loose a few 100 bytes.
How do you remember this stuff?   by Anthony Lawrence
- Unix commands: The person asking the question usually has many other things to do other than taking care of a Unix/Linux server. But even if they don't, even if their entire job revolves around their company's computer system, that's still only one system: their experience is limited.
I AM COMPUTER LITERATE   by Anthony Lawrence
- Computer literacy varies widely. Sadly, so does intelligence and belligerence. A lack of one and and excess of the other can lead to amsusing results.
SCO upgrade and CUPS   by Bill Mohrhardt
- When I was doing the Print Queues in scoadmin, I noticed that the menu would not let me 'Allow Remote Printing', as the option was in parentheses, and was not selectable. The mkdev command did not even show 'rlp' as a valid option. Being adventurous, I fould the command and executed it from its location, and it went through the motions as if it had indeed worked, and Remote Printing was set-up.
We have the brains   by Anthony Lawrence
- Former Massachusetts chief information officer Peter Quinn complains that the Linux community is unprofessional and that this is holding back more widespread adoption of Linux. I'm sure he really believes that.
Preventing DDOS attacks   by Blessen Cherian
- DDOS tries to deny important services running on a server by broadcasting packets to the destination server in a way that the Destination server cannot handle.
Caller ID Manipulation   by Michael Desrosiers
- Recently, Caller ID spoofing has become much easier and more prevalent. Millions of people have Internet based telephone equipment that can be set to make any number appear on a Caller ID system. And to make this process even easier, several web sites have popped up to provide Caller ID spoofing services. These sites eliminate the need for any special hardware or software.
Tomorrows's date   by Anthony Lawrence
- Tomorrow's date is what?: With a very little effort, almost anyone should be able to figure that out themselves: "man date" is a good start. It might take a little more effort to get to the "date +%s" solution": you might need "man strftime" also. But it is all there.
Enabling Linux telnet   by Anthony Lawrence
- This has to be one of the more common support calls that I get. The telnet daemon is no longer usually installed by default, so people are surprised when their newly installed Linux system won't answer telnets.
Recursive chown   by Anthony Lawrence
- That succesfully changed the ownership of the "dot" files, but had an unexpected (to him) side effect: /usr was also changed. Of course that would be true, because ".*" includes ".." and the ".." of /usr/fred is /usr. A useful command flag seemed to be difficult or impossible to use as desired.
