(lithium-ion-phosphate may NEVER be flattened, so even more complex) The only severe rule for mortals is to never charge A sort batteries with a B sort charger the consequences are fire and explosion. I opine that you may use the laptop permenantly 'on charge’ yet I have seen a disportionate number of dead laptop batteries contradicting what I say above. General Rule #1: Every time you flattern a battery you use up a percentage of it’s life. The ideal charger would keep the batteries at 99% charged allowing you to always charge (not 100% because the 100% level is temperature dependant and you don’t want to go to 101% because the day warmed or cooled) So if you have bought a system with a lessor charger you will buy batteries, the more you play the better the battery life, but like death and taxes dead battries.

Re: [SLUG] Weird behaviour of Intel Nuc's
On 13 Nov 2014, at 9:00 am, slug-requ...@slug.org.au wrote: So I got my hands on two Intel Nuc's for work (nice toys - small and quiet), and that other OS everyone seems to love didn't want to install on the USB disk which was stuck in them, the decision was made to go to Linux. A bit of research showed me that Ubuntu was about the only install which would painlessly go onto these things (after a BIOS upgrade), so despite my habitual distaste for Ubuntu, I downloaded a copy and installed it on the first one - all cool, boots up, able to customise it to do what I want, cool bananas. This is where is gets weird. I then proceeded to copy the USB key being used a disk using DD (to save having to customise the second one all over again). All apparently worked, both keys booted the box no worries - so I took one of them and stuck it into the second Nuc. And it flat out refused to boot. Nada. Get nicked. I thought I must have stuffed up the image - but both disks booted the first device fine. After scratching my head for a few hours and trying every BIOS option I could find, I decided to try a fresh install from the CD onto the new device - and stuff me if it didn't work. Now I'm at the point where one disk will boot on one device but not on the other. Has anyone come across this before? Is it something specific to Ubuntu, or is it the stupid SecureBoot crap (which was turned off, by the way) they put into the BIOS for these things doing *something* to the disk to make the second device not recognise it? Not really an issue, because I've fixed them so they both boot now - but I'm intensely curious as to *why* this happened. I’ve booted ubuntu, suse and arch on the atom, i3 and i5 versions.

If you want to install ThatOS then they have a tool to make a USB stick installer. On the i3 and i5 it would not boot without a bios upgrade which I did by download from intel, to a USB stick then upgrade at boot time from USB stick (yes it does offer internet update, no that did not work for me).

Ive just started getting into writing programs and I'm fooling around with
forks and daemonising processes using fork() in C.
I think the answers given so far do not address the issues:
It is twice as hard to debug a program as it is to write it. If you are as
clever as you can be when you write it how will you ever debug it?
Write it simply and clearly
eg
switch (fork ()) {
case -1:
// oops something went wrong
case 0:
// this is the parent; do anything
default:
// this is the child; do anything
}
At the do anything point there are two programs running. One is at the parent
point, one is at the child point
Since this is really quite involved in practise use the daemon system call to
handle the messyness (man daemon)
usually one does:
forks twice to break the controlling terminal links
waits for the child to terminate (see man signal) else a zombie process
happens when a child dies and noone is waiting (man wait)

The Japanese don't mind having 10x Linux Engineers in preference to 10x Train Drivers. In Sydney, sadly, they seemingly would prefer to have 10x train drivers and less Linux Engineers than have the balance the other way around.

Rather than actually address the questions posters responded with clumsy sarcasm, recast the questions in terms of their pet hobbyhorses and wandered off into moral philosophy. Closest we got was some facts about techniques for extending battery life, which is important and relevant, but I still don't know how Android compares in this area to the competition.

Usually this is more a result of their personal presentation and inability to calmly or clearly discuss their position.

Can anyone provide a simple solution or point me to a straightforward set of instructions? Jon, for simple sharing you could try using ssh sharing instead of smb. 1. check you can ssh between the machines. If not, do this on both machines: sudo apt-get install openssh-server sudo service ssh restart (you may want to later setup ssh keys and tighten security by only allowing key-based authentication if the boxes are exposed to the internet, but that's another email) 2. install sshfs and mount the remote home directory: sudo apt-get install sshfs cd ~ mkdir mnt sshfs target_servers_ip_or_hostname mnt cd mnt ls I tend to use sshf for quick and dirty sharing, and nfs/smb (samba) for longer term or higher bandwidth sharing.

Re: [SLUG] ssh key-based auth not working Ubuntu without GUI (X) login??
On 23/08/2011, at 10:00 AM, slug-requ...@slug.org.au wrote: I've come across an interesting feature on the later Ubuntu's - ssh key-based authentication to a target box doesn't appear to work, unless I've logged onto the target box through the GUI (X). Guessing here, hopefully a guess which starts you on the path to an answer. 1) I'd use ls -l to check the contents and permissions of /home/sonia/.ssh/authorized_keys you want sonia:sonia -rw--- You might want to look in /var/log/daemon.log on the target for the messages from the ssh server. 2) When you log into GNOME that starts gnome-keyring-daemon. This implements ssh-agent but looks into the GNOME keystores (which includes, but is not limited to, ~/.ssh). I do wonder if the ssh keys being used by gnome-keyring-daemon and the ssh keys in ~/.ssh/id_* might be different??? You might want to compare the fingerprints which are output in ssh -v and in the system log. Maybe command line ssh and gnome-keyring-agent are simply offering differing keys, only one of which works. I'm certain this is 'other thingz' not ssh. I use it many times every day without any issue, to 10.04, 10.10 and 11.04 as well as centos and suse, from all the above. But I go to great length to get rid of asinine stuff like the keyring where I'm led to the one-true-way.

On 24/06/2011, at 8:58 AM, slug-requ...@slug.org.au wrote: Where to start?? I have to agree with Erik De here (thanks for clarifying the real ground on which the argument stands, Erik.) and will extend the argument too. This article reminds me that there are 'Alan Jones' types all around the world and in all kinds of media and it generally cheapens the field. They take something, extract a small part and then blow it out of proportion, decontexualise it, hide the history and political elements to their claims and all along position themselves as the voice of reason and balance. Jones is a classic example of this type of journalism and this article appears to be a classic example of that type of journalism as well. For a great many people, GNU/Linux is an expression of a particular form of ethics. If you fail to generally accept those ethics then it's no surprise that swapping backwards and forwards between OSs would be seen as a reasonable thing to do. I can't say that I adhere to the same level of commitment that RMS has, but I at least aim in the same direction. To summarise my machine - it all works brilliantly well for multi-media editing (of a not particularly simple level) and I can hunt around for the best hardware at the best prices. It would appear to me that if you GNU/Linux fits your ethical position on the world then OSs which do not meet the same ethical standards would not be something you would consider for the great majority (if any) of your needs. As someone who considers the general GNU/Linux ethical argument (as espoused by RMS) I'm not in a position to merely swap when the whim takes me as it would mean going counter to an ethical position I accept as being a part of my own. Speaking personally, I'd rather contribute to an OS which has a community-orientation (not which has a *community* which is kept like serfs), which is made available to the world as freely as possible and which attempts to maintain my freedom of choice, access, use and ownership. Patrick I agree but I wonder if the ethical argument does not transend reality ... To what extent do most users *know* that they are using linux? /proc /sys /dev/shm lmsensors come to mind, the rest is GNU or GPL. I've had people - say my mother in law - using a desktop machine, here, completely oblivious to linux powering their way. I bought an iMac to run linux, linux ran terribly on it! I am now running OSX with my normal compliment of GNU/GPL apps and my desktop looks very similar to the dozen linux-only machines. EG years of frustration with evolution and kmail are quelled by this mailer, whose single vice is the bluddy-picture (I think it is gone now). I'm too old to stand in the rain with a placard, I just want it to work (tm), Not that I can't or don't admire those who do stand in the rain James-- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
