Announce: WLUG Meeting Thursday July 8 7PM
by Chuck Anderson July 6, 2010

July 6, 2010

Hi folks, Our next WLUG meeting is scheduled to be held on Thursday, July 8 at 7:00 PM in Morgan Hall at the WPI campus in Worcester, MA USA. This is an informal open meeting. Anyone who is interested in a certain topic, feel free to come to the meeting and discuss it. There has been a lot of talk about streaming music to stereo systems, so I suggest we talk about that. We'll also discuss the WLUG BBQ which is on for August! We'll go out for pizza afterwards. The meeting room is in WPI's Morgan Hall (building 'H' on the campus map [1]), down the hallway to the right of the dining hall entrance.

Grub and E-Waste
by ted June 26, 2010

June 26, 2010

Two somewhat related questions. I went to a USB keyboard after my PS keyboard broke. I am running Ubuntu 10.04. How do I get GRUB to recognize the keyboard? Second, where do I get rid of the broken keyboard? Does Worcester have an E-Waste recycling center? Thanks. Ted

I don't have a good space for hosting, but can we use one of the many fine parks in Worcester? Thats the way we rolled in Joisey. As for my USB Keyboard, the BIOS had a switch to turn on USB Keyboards and the Mouse (though I never needed the mouse for grub). Thanks for the help! Ted

RFC: WLUG BBQ July/August timeframe
by Chuck Anderson June 25, 2010

June 25, 2010

I neglected to bring up this topic at our last meeting. We usually have a WLUG summer BBQ around July or August, so I'd like to get the planning discussion going now. Are people interested in having a BBQ this year, and if so, would someone be willing to host it? WLUG should enough in the bank to fund the food (Andy can you confirm?), so all we need is a place with a BBQ grill and a time. Comments? Ideas? -Chuck

Converting VSAM files
by Michael Long June 24, 2010

June 24, 2010

Hi: I have a project in which I need to migrate some data stored in VSAM files to a relational database (mssql). I am wondering if anyone has had experience with extracting data from a VSAM file to a flat file. If so what tools would you recommend to make this happen. tia, Mike

232-TTL, locally?
by soup June 8, 2010

June 8, 2010

Anyone know of a hobby/electronics shop where I could get a 232-TTL dongle, board or kit? Even just a bare MAX232 IC would be cool. I don't want to have to drive up to you-do-it, that's the only place I can think of that's left... Take care, soup

Awk Null Field
by Gary Hanley June 1, 2010

June 1, 2010

Wow, what's wrong with me? I'm trying to parse a file to eliminate any line from the file to the output where a particular field is is null. The 8th field in this case. I can't get it right! I haven't done an awk script in a long time but this should be simple stuff. Basically I'm trying to do: cat file | awk -F\| '$8 !~ <NULL expression> {print}' Any help would be appreciated. Thanks. -- Gary
