disk usage

Here's another attempt to send this out: I copied a bunch of stuff with rsync from a Linux system to a BSD system. I'm fairly sure it worked fine, but as a check, I'd like to compare the total number of bytes in files on both systems. du -sk <dir> produces slightly different results on both systems (smaller on dest) I also tried out find <dir> -type f -print0 | xargs -0 stat --format=%s | awk '{s+=$1} END {print s}' on Linux and find rsync -type f -print0 | xargs -0 stat -f %Dz | awk '{s+=$1} END {print s}' on BSD. I think they're equivalent, but maybe not. At any rate, this also produced differing results for each system, with the destination having the smaller numbers. Not a huge difference, but it leaves me wondering what might be missing. Any ideas?

by Adam Thompson 10 Jul '17

10 Jul '17

For all those who might be interested… From: Mak Kolybabi [mailto:mak@kolybabi.com] Sent: July 10, 2017 08:35 To: athompso(a)athompso.net Cc: cfp(a)bsideswpg.ca Subject: BSides Winnipeg 2017 CFP The BSides Winnipeg 2017 CFP is open from now until August 16th. Please find the text of the CFP below, as well as the PDF version attached. -Mak Call For Papers BSides Winnipeg 2017 occurs on November 4th & 5th, and will consist of a single speaking track. Presentations are expected to be 20 to 25 minutes, followed by a few minutes for Q&A. Like all BSides, we especially encourage people that have never presented before to submit to this CFP! We are looking for presentations that talk about infosec tools, specific exploits, legal issues, privacy, defensive and offensive measures, cryptography, password cracking, reverse engineering, lockpicking, and software-defined radio. If your presentation doesn't fit into any of those categories, pitch it anyway! Submissions should be in plain text and answer the following questions: * May we refer to you by your name? If so, what is your name? If not, by what pseudonym should we refer to you? * What email address should we use to contact you? * What is the title of your presentation? * In one paragraph, provide a description of your presentation (i.e. an abstract) * Who are you, what are you known for? * Has this material been presented elsewhere? If so, where and when? * Are you presenting as a representative of: * Yourself? * A company? If so, what is its name? * A group? If so, what is its name? * Will you be traveling to the event? If so, from where? Failure to answer any of the above questions will likely result in your submission being summarily rejected. Any talks we feel are marketing or sales pitches will definitely be rejected. We will live stream, and record for online distribution, all presentations made at the event. Your name (or pseudonym), the title of your presentation, and your presentation’s abstract will appear in several places and be posted indefinitely along with the recording of your presentation; take some time to consider what to write for them. Submissions must be emailed to <mailto:cfp@bsideswpg.ca> cfp(a)bsideswpg.ca. The CFP opens on Saturday, July 1st and the deadline for submissions is Wednesday, August 16th. Each submission that we receive will have its receipt confirmed within 24 hours, for your peace of mind. You will be informed if any information that we require is missing. Every submission will be responded to by Friday, September 1st with our decision as to whether it has been accepted. Speakers will receive a complimentary ticket to the event, and a token of our appreciation. All submissions are greatly appreciated, but we're running a single track for two days, so there are limited slots available, constraining the number of presentations that we can accept. If you have any questions about the CFP or the conference, please email the organizers at <mailto:organizers@bsideswpg.ca> organizers(a)bsideswpg.ca.

No cottage for me. I'm still here and enjoying this whole thread, which strikes a real chord with me. I've made many similar observations in my IT life. Even as far back as circa 1988-1990, I remember an IT journal article entitled "The End of Programmers (Again)". Non-programmers generally don't even understand or appreciate the concepts of algorithms and processes, and seem to think that a simple script without conditional logic/branching can do everything.

Linux "write"
by Trevor Cordes 07 Jul '17

07 Jul '17

Can someone else confirm this bug on another Linux system, preferably a modern one that uses systemd? In X, as non-root: open a term (call it term1) open another term (term2) type "tty" in term2, not your tty number/string in term1: type "write <your-login> <tty-string-from-above>" replace your-login with the output of "who" if you don't know who you are logged in as please try both /dev/pts/42 and pts/42 format for the tty part of write example: write trevor pts/42 When I run this I get: write: trevor is not logged in on pts/42 Even though I clearly am. This used to work perfectly up until last year (I think), and I think systemd changed something (big surprise). No chatter about this anywhere that I can see. Probably the last person on earth to use write (at least on F24). I found some other things to test that indicate that something is really amiss: >write trevor write: trevor has messages disabled >mesg is y >mesg y mesg is y >write trevor write: trevor has messages disabled >ll /dev/pts/42 crw--w---- 1 trevor tty 136, 42 Jun 28 02:48 /dev/pts/42 If someone else can confirm this bug on a non-Fedora (or a newer one) that would be great. If someone can also confirm that the above behaviour is insane, that too would be great. If anyone has some ideas on what to try next, shoot away! Then I'll file a bz. Thanks!

laptop HD's
by Dan Keizer 10 Jun '17

10 Jun '17

OK, so first off, thanks for all your guys feedback on my prior posting about a young guy's interest in a computer gaming system. I passed along the info - not sure where/how far it went ... good info anyways. on another front, the laptops i've purchased for myself/house I've replaced the spinning metal with SSD's. I've then given some of these spinning metals away. Now, there's an interest to get a couple/few spinning metal drives to put into laptops for casual use for some other peoples ... Does anyone have any source for older laptop hd's ... even as small as 20gb or so would be fine (they are probably hard to find too) ... there's a couple i'm looking for in the next while ... Thanks. Dan.

MUUG Meeting, June 13, 7:30pm -- BSDCan 2017 Report
by Gilbert E. Detillieux 06 Jun '17

06 Jun '17

*** Please note the updated meeting location below *** The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, June 13. The meeting topic for this month is as follows: BSDCan 2017 Report Adam Thompson will be reporting on his recent visit to the 14th annual BSDCan. BSDCan, a BSD conference held in Ottawa, Canada, quickly established itself as the technical conference for people working on and with 4.4BSD based operating systems and related projects. The organizers have found a fantastic formula that appeals to a wide range of people from extreme novices to advanced developers. Daemon-Dash: rsync In the Daemon-Dash segment, Wyatt Zacharias will demo the rsync daemon. When run as a daemon, rsync allows clients to directly connect and retrieve files, without the need for SSH encapsulation or shell access. The group usually holds its meetings at 7:30pm on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend. ****************************************************************** Please note our *NEW* meeting location for this month: *Room 2L17* Lockhart Hall, University of Winnipeg, entrance on Ellice Ave. between Spence St. and Balmoral St. Parking is available on the surrounding streets and in the lots on nearby streets. Look for signage once you're at the building, or ask a security guard. ****************************************************************** For more information about MUUG, and its monthly meetings, check out their web server: https://muug.ca/ Help us promote this month's meeting, by putting this poster up on your workplace bulletin board or other suitable public message board: https://muug.ca/meetings/MUUGmeeting.pdf -- Manitoba UNIX User Group E-mail: <gedetil(a)muug.ca> c/o Gilbert E.
