It had nothing to do with linux mint. That is what you wrote then. However it is not really based on any data. At the time IBM really wanted to continue developing its own fork of OpenOffice and for that they did not want OpenOffice to continue with the LibreOffice fork, that already existed (and had a license that would prevent them from making a priprietary fork). That is the most probably cause for Oracle to move OpenOffice to Apache. Stallman wasn't really involved with LibreOffice at the time.

When I installed it, it defaulted to a regular ext(something) boot partition, and an lvm partition with everything else on it. There now is a bad spot in the lvm partition. fsck with a read check does not find it. I have moved enough data off of it, so it wont show up in a file copy. I will have a new drive tomorrow, intended to replace the old one. The old one is 300 gig, the new one is 1tb. Normally, I would just partition it, make both file systems ext4, copy the files and run grub. The lvm volume is something I dont understand. If there a diskcopy type utility that would do all the work for me? Is there a howto? Can I just make the root an ext4 partition on the new disk and skip the lvm? What would I have to change? I assume grub.conf and /etc/fstab. Anything else? I'm not exactly sure what it is that you want to do. One thing you can do is (for the time of the transition), connect the new, and then ask LVM to move the data to it. No need to mess with fstab. Disclaimer: I didn't test the commands here, I don't play with LVM that much. I assume you have a logical volume called LV, that the old physical partition is /dev/sda2 and that the physical partition is /dev/sdb2[1] . 1. Partition the new disk. Create (among others) the partition of type LVM /dev/sdb2 2. Make that partition a physical volume: pvcreate /dev/sdb2 3. Add the new partition (physical volume) to the logical volume: vgextend LV /dev/sdb2 4. Move information from this physical volume (this should take a while): pvmove /dev/sda2 5. Now you can ask LVM to remove the old physical volume (partition) from the logical volume: vgreduce LV /dev/sda2 [1] This is the name it happens to have right now. It's not the name LVM identifies the partition anyway: it identifies it by an ID written inside the physical volume. -- Tzafrir ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

Standard udev rules create on my system the following 4 subdirectories
under /dev/disk:
by-id by-label by-partuuid by-path by-uuid
Each directory has symlinks to either a disk or a partition. One of
those should describe your external disk properly.
If this is not good enough, you can make your own.
$ cat /etc/udev/rules.d/90-backup-usb.rules
ACTION=="add", ENV{ID_FS_LABEL}=="backup-boole-*", \
SYMLINK+="backup"
And in fstab:
/dev/backup /mnt/backup ext4rw,noauto 0 0
There are several backup disks with different labels. The backup disk
that is connected is mounted by the backup script, but /dev/backup is
created by the udev rule.

However, from what I know of Thunderbird, it is basically written on top of Gecko, and thus works with HTML, CSS and such.

How do I translate a document to HTML from the command line? BTW: something I read a while ago on Planet GNOME: http://thedocsbook.org/blog/2015-02-23-reflecting-on-feedback/ "In terms of modifying the appearance of our help, their technical writers found it difficult to modify the CSS that we use. Cosimo noted that the CSS for our help is not stored in a single file, nor even a single directory - it's partly embedded in Yelp's XSLT. While not always ideal, there are reasons for this. For example, if a person's visual impairment requires that they use GNOME's High Contrast GTK theme, Yelp will pick up the theme change and will use a corresponding color scheme when it renders the help for that user. Similarly, if a user sets their default system language to a Right-to-Left-based language (such as Arabic), Yelp will also pick up that change, and will display the help in the appropriate Right-to-Left manner automatically." -- Tzafrir Cohen | tzaf...@jabber.org | VIM is http://tzafrir.org.il || a Mutt's tzaf...@cohens.org.il || best tzaf...@debian.org|| friend ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

setxkbmap's -option needs resetting. If you follow this, try:
setxkbmap -option '' -option grp:switch,grp:shift_toggle,grp_led:scroll us,il
,lyx
Note that in the latest versions, the keyboard mapping includes the
latest version of SI1452:
https://www.mediawiki.org/wiki/Help:Extension:UniversalLanguageSelector/Input_methods/he-standard-2012-extonly/he
For this you should use something along the lines of:
setxkbmap -option '' -option \
"grp:shift_toggle,grp:switch,lv3:ralt_switch"
\
us,il
Like the above, but the right alt is used to switch (temporarily) to
third shift level, where most Nikkud signs are.

There wasn't that much good BSD code out there when the GNU project started. BSD started provided a complete system at the beginning of the 1990-s. And shortly thereafter it got into a trial with AT&T. Also shortly after development was halted and much of it moved to proprietary forks.

As it happens I believe that this happens to be a good sign: IIRC of the cheapo chipsets, only 2 have them, and both have a pretty good community support. This specific device is based on Allwinner A31. Unlike previous Allwinner chips which use the Mali GPU, this one uses PowerVR. If you hope to have free drivers for the GPU, this may not be the best for you. See also below regarding community support. The more proprietary drivers, the more difficult it is to have community support. Here is a similar item from the store of someone who is one of the developers involved: http://store.r0ck.me/products/mele-m5-tv-box (sold out, right now) That model comes with a dual Cortex A7, that is: a less powerful CPU (but it also means: requires much less power) > > The main reasons is that it cost $100 (US) for the unit, and it > includes a quad core ARM chip.

Older versions than 4 won't run modern Apps. I have no idea about newer versions, but from an initial glance over the wiki, there's at least some work done to get newer versions working.

Can you afford a periodic scan by some service? I figure you could always trigger it with inotify otherwise, but there is an overhead. http://dedup.debian.net gives the following advice, that I have not yet tested: # Replace duplicate files with symlinks rdfind -outputname /dev/null -makesymlinks true debian/mypackage/ # Fix those symlinks to make them relative symlinks -r -s -c debian/mypackage/ > 1.

Is there any benefits that I didn't notice? The benefits are keeping your changes separate from the system. The maintinance is much simpler (it is feasible to maintain them under version control). I'm not exactly sure if Ubuntu uses Debian Live or something different (ask its developers).

What's the problem with building it from scratch? That's the same procedure used by the builders of the image you use.

A Raspberry Pi is relatively cheap, but is certainly not the only small device around. http://linux-sunxi.org/Mele_A1000 Includes a SATA adapter and a disk enclosure (you'll have to provide your own disk). It does cost a bit more than a Pi, and the code is not in mainline yet, but it's easier to work with than a Pi.

A version or two of Ubuntu had such a setup as th default, IIRC. They made the extra stuff added on top of screen in a separate package called byobu. It still seems to be under active maintinance.

SSH can be used for various things (ssh, scp, whatever). I normally keep at least one active shell session and occasionally use minor ones for tab completion (of scp and such. Check out /etc/bash_completion/ssh ). In order to avoid the overhead of several SSH connections, I use a socket so that the various commands will use a single TCP connection and SSH session (the one of my main shell session).

Patent Trolls are a indeed managable parasites. But, as the article states, the damage is a tax. And those who can least aford to pay it are small companies.

Notes are not a precise enough description of the music. There certainly are some synthesizers around. Getting them to produce an exact copy of some specific instrument may be tricky. Something which is potentially less tricky is getting them to produce a reproducable sound: Being able to produce exactly the same sound from your sound system.

Well, past episodes have been interesting. The RedHat Marketing
("Community", technically) guy was very pushy and avoided questions he
did not want.
In the recent weeks they had e.g. Remind, Autotest and Stutnt Rally,
which were completely "non commercial". They also had FreeNAS, which
hadtwo people from the company that maintains FreeNAS (and also a
"value-added" version of it. They have not avoided technical aspects,
and actually did get a bit into the business side of it and how it works
with Free Software.

Nope. AbiSuite never made anything more that Abiword.

At the same time, I'll have a more easier "marketing job" to do. Are you interested in a read-only or read-write format? While it's your fight to pick and not mine, I'm not sure I'd be happy if a result would be the replacement of one proprietary format with another. -- Tzafrir Cohen | tzaf...@jabber.org | VIM is http://tzafrir.org.il || a Mutt's tzaf...@cohens.org.il || best tzaf...@debian.org|| friend ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

In other words: while an account at Google does not cost money,Google Docs is just as proprietary as MS-Office and Acrobat Reader[1]. I would not have wanted to be forced to have an account there in order to interact with school. [1] PDF itself is not bad as it has some other good alternatives implementations.

Talking's easy. If you care so badly about that, install e.g.
CyanogenMod on your phone, and don't install any of the properitary apps
(they are not included in the main CyanogenMod distribution).
Free Software is not very useful when it is a single program. It becomes
an obvious atvantage when it is a complete stack. Free Software has its
hands tied behind its back in a proprietary application market where
dependencies are frowned upon.
Next set up a build environment on the phone.
Also note that with the help of qemu and schroot you can get a
natively-looking arm chroot on your own Linux PC, assuming that Android
processes will run on a standard Linux kernel.
That said, another issue is the non-free software you use indirectly
through cloud service providers. But that is a different issue.

/bin/sh ? There are plenty of others, actually.
