Hi folks! I will be introducing OpenSCAD, a DSL for CAD modeling. It is a finite, functional scripting language that outputs shapes ready for 3d printing. It has a C like syntax that is parsed into an OpenCSG tree, that is then compiled down to a .stl triangular mesh. It supports all source code version control unlike most 3d design software, and also has a powerful library system for modular designing. If you install it ahead of time (or when you get here) i can do a live coding walk through. http://www.openscad.org/ http://www.openscad.org/cheatsheet/ On May 3, 2014 12:00 PM, <wlug-request(a)mail.wlug.org> wrote: > Send Wlug mailing list submissions to > wlug(a)mail.wlug.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://mail.wlug.org/mailman/listinfo/wlug > or, via email, send a message with subject or body 'help' to > wlug-request(a)mail.wlug.org > > You can reach the person managing the list at > wlug-owner(a)mail.wlug.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Wlug digest..." > > > Today's Topics: > > 1.

OT: Looking for ISP
by Richard Klein May 7, 2014

May 7, 2014

I'm moving back to Worcester after 5-ish years. I used speakeasy for DSL when I lived near Indian Lake, but they aren't the same company anymore, and the new place is just off Hope Ave, by the cemeteries, Hadwen Park, and the Auburn line. Can anyone recommend a good ISP out that way, or a good website to find an ISP? -- Thanks! Rich

Agreed on Charter being the only choice for Woostuh, where I lived and worked through the glorious 1980s and again briefly 2006-06 and 2010. That wottuh problem under Southbridge Street is due primarily to runoff from the hills above it PLUS the Blackstone River tributary which they built the street and 290 over back when.

Announce: May meeting? Yes! See the Technocopia hackerspace.
by Chuck Anderson May 2, 2014

May 2, 2014

Kevin Harrington has volunteered to give WLUG a tour of Technocopia, a new maker/hacker space just a few blocks from campus. He's also volunteered to talk about a programming language I forget the name of. I figure we could meet in the Campus Center, and then walk down to Technocopia. So here's the plan: WLUG Meeting Thursday, May 8 2014. 7:00 PM meet at WPI Campus Center, Chairman's Room. 7:15 PM or so, head down to Technocopia, 95 Prescott Street, Worcester, MA 01605 More information about the hackerspace is available here: http://technocopia.org/ We'll go out for pizza afterwards.

So is the may meeting going to be on the 8th? If so.. does anybody have a burning desire to talk about something? Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Fedora Next
by dulsi＠identicalsoftware.com April 29, 2014

April 29, 2014

Recently I decided to try to get my program Bt Builder into Fedora (https://bugzilla.redhat.com/show_bug.cgi?id=1079064) They identified some issues during review which I've fixed. Initially I didn't do the "introdution" email to the devel because I was joining to package my project and eventually maybe some others. I did eventually join the list and send the email. However I've also been reading the Fedora Present and Future articles on the Fedora Magazine site http://fedoramagazine.org/fedora-present-and-future-a-fedora-next-2014-upda… It's left me wondering if I should bother going with sponsorship into Fedora. I can setup a COPR and perhaps move into the distribution via the Playground. Do you Fedora will continue with the current sponsorship model? Will new projects instead come in through the personal repositories of COPR?

Lightning Talks @ LOPSA-East 2014!
by Evan Pettrey April 25, 2014

April 25, 2014

LOPSA East 2014 starts in one week! All the talks have been scheduled, all the tutorials and instructors have been book, now all you need to do is show up, right? In http://scottberkun.com/essays/24-how-to-get-the-most-out-of-conferences/ Scott Berkun (author of five books, including _The Year Without Pants_) states: "There is no better way to meet others and access the most interesting and friendly people than participating." The good news is that even this late in the game, there's still a way you you to participate: Lightning Talks! Lightning Talks are a series of five-minute talks (no slides!) where enthusiasm is paramount and almost anything that might be of interest to sysadmins is on-topic. Have an idea for a talk or tutorial for a future conference you want to try out? Give a Lightning Talk. Want to share a cool new trick with your peers? Give a Lightning Talk. Have an idea for a tool and want feedback? Give a Lightning Talk. Want to convince your peers to change how they do their jobs, or quit their jobs, or not to make the same mistake you did, or step away from the keyboard and learn to cook? Give a Lightning Talk. The Lightning Talks session is Saturday, May 3rd, at 3:30 p.m. There's room for at least nine talks, more if people use fewer than their allotted time (five minutes). To sign up for a Lightning Talk, send email to <lightningtalks(a)lopsaeast.org> or contact the Lightning Talks coordinator (Adam Moskowitz) at the conference and sign up in person. Talk slots are on a first-come, first-served basis; there will be a waiting list, and if there's time at the end of the session you can just step up to the microphone without signing up in advance (but don't count on this as all the slots are usually taken). Remember: Five minutes (hard limit), no slides, pretty much any topic. Yes, even cooking -- if you can find a way to tie it to system administration. There's no easier way to actively participate in the conference than to give a Lightning Talk! Best regards, Evan & the rest of the LOPSA-East Committee

Tripwire vs rpm -V
by Eric Martin April 18, 2014

April 18, 2014

I have a weird problem with tripwire on at least two of my servers. A run of tripwire --check shows a few tripwire binaries have changed, which since I didn't do it is very suspicious: ------------------------------------------------------------------------------- Rule Name: Tripwire Binaries (/usr/sbin/tripwire) Severity Level: 100 ------------------------------------------------------------------------------- ---------------------------------------- Modified Objects: 1 ---------------------------------------- Modified object name: /usr/sbin/tripwire Property: Expected Observed ------------- ----------- ----------- Object Type Regular File Regular File Device Number 64768 64768 * Inode Number 9698 10390 Mode -rwxr-xr-x -rwxr-xr-x Num Links 1 1 UID root (0) root (0) GID root (0) root (0) Size 1145520 1145520 Modify Time Mon 05 Jul 2010 08:55:49 PM EDT Mon 05 Jul 2010 08:55:49 PM EDT Blocks 2240 2240 * CRC32 XXXXX YYYYY * MD5 XXXXXXXXXXMJedgAef0 XXXXXXXXXXPFRiVSdGoG/q The inode number is fine, it's the CRC32 and MD5 sums that worry me. As per my usual procedure, I then issue rpm -V ${PACKAGE_NAME} to verify the package: [emartin@mx1 ~]$ sudo rpm -V tripwire S.5....T. c /etc/tripwire/twpol.txt I expect twpol.txt to be changed since you update the policy. What is / isn't missing is the glaring alert that tripwire doesn't match the RPM. Also, the MD5 sum in tripwire on one machine doesn't match it on another, and neither do the SHA1 sums as computed from the command line. While I'm pretty good with CentOS, there are a few things that I'm still learning so I'm thinking that I'm missing something here. Can anybody please shed some light on this, especially the differing sha1sums? If these are binaries, shouldn't they have the same sha1um? Also, do I need to blow away this machine and rebuild? TIA, -- Eric Martin

Mail User Agent: mail (/bin/mail)
by Larry Camilli April 11, 2014

April 11, 2014

This message has two parts. The first is about the basic mail program. The second (which is more important to me) is about how to avoid having to use the mail program. Part I: The Basic mail program (I'm running CentOS.) I asked last night about the basic mail program - specifically about navigating through the headers. Chuck looked up some documentation and said that the "h+" and "h-" commands should do it. And, somebody came up to me with his laptop and showed the "z" command.) Here's what the help file within mail shows about the "z" command: (Yes. -It says nothing about the z command.) Here's what I found with the h+ and h- commands: When I invoke mail, it displays the headers of 38 unread messages (numbers 1 - 38) and a prompt ("&"). (The terminal window is 132 characters wide by 42 lines long.) If I type h+, it displays the same 38 headers again. (h- gets "Referencing before 1") If I type h7865782365, I get "Invalid message number". If I type h 1-a, I get "Non-numeric second argument". If I type h 1-4, I get the first 38 headers. The program seems to be parsing what follows an "h", but royally screws up acting on what it finds. If I type "39", I get message 39. (There doesn't seem to be a "LAST" command to see the last message - and find out its number. So, typing, say, 100, gets an error because there's no such message.) Anyway, after viewing message 39, if I THEN type h, it shows headers for messages 39 - 51. (h+ shows the same headers, 39 - 51.) But, h- now shows the first 38. (That makes sense.) But, after using h- to get back to the 1 - 38 list, h+ shows the first 38 messages again. After displaying the first 38 headers, the "z" command DOES cause the next set of headers to be displayed (39 - 51). I figured that, until I figure out how to set things up to forward the logwatch mail to a gmail account, I could tolerate using a separate, basic mail program to check the logs. But, this is crap. People were asking about the guy who screwed up the OpenSSL heartbeat code. What about the guy who wrote this piece of crap? It's very basic stuff that doesn't work. Not too difficult to test... Part II: Getting EMail Forwarded from the Linux System as a Client I have two interests here. One is just academic. -Understanding how to use the mail program, despite (or because of) its suckiness. The other is so I can see the messages that the log scrapers send via /bin/mail to the root account's email. Ideally, I would set things up to have all of root's email get forwarded to, say, a gmail account. But, my setup seems to place some limits on what I can do. I set up an MTA on my VMS box long ago. I used to be able to send email directly from that system. But, it stopped working at some point, and I found that Verizon reports all of the DHCP addresses that they allocate to residential DSL customers as spam sources, so everything was getting blocked. I have written programs (in PHP) that use a PEAR class/API to send email from the Linux box, via a gmail account, to arbitrary addressees. [It requires such information as host (smtp.gmail.com) port (587), username & password for the gmail account...] So, I'm not sure if an MTA is what I really need. Can at MTA be set up to send email as a client of sorts to a real MTA (e.g., google mail)? Or do I need some other type of utility? Sure, I can write my own, but I would hope that somebody else has already done it. (Well, as long as it's not the person who wrote "mail".)
