Capturing output
by Jay Amorin 01 Oct '13

01 Oct '13

Hi All, I have this crazy problem and I hope it is possible. Part in my script: svnadmin dump -r1:100 --incremental /srv/my_repo > /srv/my_repo.1-100.dump Output: * Dumped revision 1. * Dumped revision 2. * Dumped revision 3. * Dumped revision 4. * Dumped revision 5. * Dumped revision 6. * Dumped revision 7. * Dumped revision 8. * Dumped revision 9. * Dumped revision 10. Now I want to store the output (standard out/error) to a log file for future reference using this: svnadmin dump -r1:100 --incremental /srv/my_repo > /srv/my_repo.1-100.dump | tee /srv/my_repo.1-100.log But seems not to work. Is this doable with bash or python? TIA, Jay

From: "Peter Nunn" <pnunn(a)infoteq.com.au> > At the risk of starting a thread that runs for months, how do you > overcome microsoft FUB in the education sector. I only see one way to establish open education in a school. You have staff that believes in values, as creativity, curiosity and privacy. Staff motivated to put some effort in it. Then you can back them by providing support. Economical values, usability etc. shouldn't be at the heart of the discussion. They follow if the motivation is there. I give you an example why I believe the staff and their motivation is most important. My daughter has Apple instead of Windows. Caged farming compared to Windows. At least you can easily transfer data from/to a Windows system. Some of the iPad apps suck soo much that I would throw them out after an hour. It also prepares the next generation to send their data feed directly to the spies. Who would save or exchange data via USB stick? Apple makes it so much easier. Just use iTunes. Or Windows Live. Or Google.. whatever the product and the cloud of the day is. At Albert Park College the iPads are integrated part of all classes, every student has to buy one, and for students class 8 and above Mac computers are mandatory too. The staff seems to be enthusiastic to have modern devices to work with and a bunch of apps they consider useful and hip. There are free alternatives but I guess there is no way to counter that. Apple is seen as cool and it fits into the image of a "modern school". Well, we are living in the age where the image of a school is more important than education itself. Because we have a school market, parents shop around. We do not have schools simply to educate kids. I had endless hours, week by week, month by month, parents talking about "the best college for my child". It simply sucks. $1500 per student, 150 students per year, 7 years at the school makes it ca. 1.5 million dollars private spending on devices. Plus the IT budget in the school.. I use open source, my kids are familiar with it and they used some at home. But they do not stand a chance against a whole society brainwashed to believe in brands. Imagine another approach: Some Linux computers for teachers at the school, and the school starts with kids building their computer from a Raspberry Pi, and then install Linux on it, learn how to understand a computer works, how to make a case etc. The teachers in the class room can add Scratch, Audacity, GIMP etc. That's not too hard but needs some motivation. I made a garden bench last weekend. It does not matter too much whether it is a fancy one. The kids were enthusiastic, sawing and filing and drilling and screwing - and the finished furniture is the most loved item afterwards. Regards Peter

Samba 4 AD provisioning and ZFS
by Petros 30 Sep '13

30 Sep '13

Hi all, is someone here familiar with Samnba 4 and especially the samba-tool written in Python? The story so far: Samba4 can work with ZFS, and is able to use the default s3fs. The trap: the samba-tool provisioning script does not work with ZFS. Reason according to Andrew Bartlett a few days ago: "The issue is essentially that the python-based provision code need to detect the use of zfs, load the zfsacl module in the generated smb.conf, and instead of testing simple posix ACLs, proceed to setting a full NT ACL when we create the sysvol share." I am not familiar with python but had some limited success in reading the code. Anyway, a look at lib/python2.7/site-packages/samba/provision/__init__.py let me suggest that I may - test whether zfs is there (e.g using libc.getvfsbyname("zfs", byref(info)) - add lines as "nt acl support = yes" into the smb.conf - load the zfs_acl.so module (how?) - modify the test when creating the SysVol (at the moment smbd.set_simple_acls) I wonder whether anyone could help a bit. My main problem is the loading of the module. I could not figure out how to do it, especially what's the proper "Samba way". Thanks for help Peter

"chroot: failed to run command '/bin/bash': no such file or directory" So, it would seem that I'm missing something. When you said "Try to mount all your partition under /mnt and run chroot" did you imply some other things needed to be done that you didn't list? As I said I am using Knoppix live, which is a 32 bit version. The system I'm trying to rescue is 64 bit. Is that an issue? In an attempt to see if I could get a bit further I booted a 64 bit system in rescue mode, but that doesn't provide grub. Cheers, -- Regards, Terry Duell

I have a production PC running LMDE that I will need to upgrade at some point, a process that will include the same jump from grub-legacy to grub-pc as you've just fought with.

Replicator model detaching
by Russell Coker 29 Sep '13

29 Sep '13

I've got the LUV Makerbot Replicator working, I will demo it at some meetings some time soon. One problem I'm having is that the model in progress will often get detached from the platform. The "Calibration Dual" model file that ships with the replicator has become detached three times, each time the front left corner lifts from the platform first and then eventually it all comes unstuck and the model is destroyed. I tried the "Cube Slide" model file that ships with it once and it detached when it was on the last black segment, so the model was mostly OK but it's still not a successful result. Any suggestions for how to deal with this? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

ALSA capture not working
by Neale Banks 28 Sep '13

28 Sep '13

Hi, This is on a fresh install of Debian 7.1 XFCE AMD64 on an Optiplex 780. It's multiarch - i386 added so Skype i386 can be installed. Skype appears happy, but calls to the Echo / Sound Test Service don't return my audio. The simplest manisfestation of this problem is that ALSA capture doesn't capture anything, but silence. I'm using: arecord -d 5 --vumeter=mono /tmp/foo.wav The meter doesn't move, and playing back with: aplay --vumeter=mono /tmp/foo produces silence (but playing another .wav file is OK). In alsamixer, I've maximised all Capture settings, and have set the input sources (both of them) to "Front Mic" (this _should_ be the correct input - the Mic is connected at the front and in the playback devices cranking up "Front Mic" results in the Mic audio going to the headset (i.e. sidetone)). According to lspci, the audio device is a: "Intel Corporation 82801JD/DO (ICH10 Family) HD Audio Controller (rev 02)" Curiously, we had the same problem with a completely different machine earlier this year - all OK but Microphone Capture not working (Debian installation report at: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=701171 We never "solved" that - the workaround was to use a "USB" headset/microphone (i.e. USB Sound "card"). Any suggestions? Thanks, Neale.

ls -l *.mkv *.avi *.mp4 The above command will give me errors if I happen to have no .avi files or no .mkv files. How can I write a command to give a list of all video files and not give an error if some don't exist? Preferably in bash, but I'm willing to try another shell if necessary. As an aside I'm not actually after running ls, the below is what I'm really trying to do: for n in *.mkv *.avi *.mp4 ; do -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Fwd: [lca-announce] lca2014 keynote - Jon Oxer - ArduSat
by Bianca Gibson 27 Sep '13

27 Sep '13

---------- Forwarded message ---------- From: "linux.conf.au Announcements" <lca-announce(a)lists.linux.org.au> Date: 27 Sep 2013 16:37 Subject: [lca-announce] lca2014 keynote - Jon Oxer - ArduSat To: <lca-announce(a)lists.linux.org.au>, <chat(a)lists.lca2013.linux.org.au>, " plug(a)plug.org.au" <plug(a)plug.org.au> Cc: Public Release. For immediate Release. The linux.conf.au 2014 team are excited to announce our first keynote speaker - Jonathan Oxer. Jon has agreed to come and present a keynote discussing ArduSat. Jon has been hacking on both hardware and software since he was a little tacker. Most recently he's been focusing more on the Open Hardware side, co-founding Freetronics as a direct result of organising the first Arduino Miniconf at LCA2010. His books include "Ubuntu Hacks" and "Practical Arduino". Jon has been variously referred to as Australia's geekiest man and as a cyborg-in-progress. As part of his “SuperHouse” home automation series, Jon has taken keyless entry to an all new level by embedding an RFID tag into his arm using a vet's chipping tool. Recently he has been working on ArduSat, a satellite that aims to give hobbyists, students and space enthusiasts an opportunity to design and run their own experiments in space. By choosing a standardised platform based on the hugely popular Arduino hardware design, ArduSat allows anyone to develop and prototype experiments at home using readily accessible parts and all based on a simple open source software environment. Jon will be presenting an overview of the latest developments to the ArduSat project as part of his keynote presentation during linux.conf.au2014 in Perth, Western Australia. linux.conf.au is an annual open source conference organised by Linux Australia. In 2014 the conference will be held in Perth, Western Australia from the 6th January to the 10th. http://linux.conf.au #lca2014 -- Kind Regards Luke Woollard luke.john(a)osmahi.com _______________________________________________ lca-announce mailing list lca-announce(a)lists.linux.org.au http://lists.linux.org.au/listinfo/lca-announce

It would be better if you have the livecd or install cd, but you can also use other livecd as well e.g. knoppix. root (hdx,y) setup (hdx) x is the mbr usually points to hd0. y is the partition where your grub stage 1 is, just press the tab key to auto-complete. Let us know if it works.
