Despite the fact that parenting is not on my radar yet, when I spotted Let's talk parenting taboos: Rufus Griscom + Alisa Volkman on the TED RSS feed I was curious what it was about. Various aspects made the talk well worth my time. Maybe it's worth yours, too.
Hello! I have written a small tool klogripper to continuously extract the log from the Kernel's ring buffer, something dmesg does not seem to be able to do. Building klogripper is trivial:
git clone https://github.com/hartwork/klogripper.git cd klogripper make
On the implementation: As calls to
always returned 0 here (-1 without root permissions), I use
SYSLOG_ACTION_READ_ALL, instead. On each call the resulting content is
compared to the previous run, and any possible overlap is cut off. The result
is a continuous stream, allowing to follow the log in real time. In case you
write patches for it, please feed them back to me. Thanks!
Hello! If you're wondering what rss2email is good for: one use case is combining it with IMAP so you can remember reading state across different machines. So... I have just bumped rss2email to version 2.69 in Gentoo. Before bumping, I have package-masked the upcoming version, because the packaging of 2.65 and 2.69 differ heavily. If you are using rss2email please give the new version a try in a non-production environment and open bugs as needed. Thank you!
When I finally accepted that you cannot do serious work on a single-core 1,3GHz notebook machine with 500MB RAM (running Xubuntu, to save compilation and manual disk encryption setups) I started looking for a notebook fast enough to really run Gentoo.
I was looking for ..
- a Lenovo machine
- Intel dual-core 2GHz or more
- 4GB RAM or more
- 14.1'' 16:10 display with more than 1024x768
- CD/DVD drive
- 200GB disk or more
- any non-NVIDIA graphics card
- 3x USB or more
Variations of T400, T410 and T400s seemed to be my options. I went to buy a T400 and started feeding Gentoo to it. These details may be interesting:
~amd64system, stable GCC, XFCE, and a bunch of KDE4 apps mixed in
- Full disk encryption (including swap)
/var/tmp/portageon 2GB tmpfs
- WLAN works, sound works, even camera works. (Card reader, FireWire, modem, GPU switching, and hibernation untested)
On the hardware
- Machine fast enough for Gentoo compilation fun (Core 2 Duo T9400 @ 2.53GHz, 4 GB RAM). See compile times below.
- Good keyboard (both typing and layout)
- Rather low noise so far
- Excellent Linux support so far
- Small keyboard (buffering?) issue still to be resolved. May be on software level though, no idea.
- No fingerprint reader
Things I learned
- Setting up disk encryption (LVM over dm-crypt) on the shell.
- Building an initramfs using genkernel. Awesome pointer by rbu, thanks!
- How li-io batteries like to be treated and what tp_smapi can do to help.
- Setting up NetworkManager.
- ThinkWiki and Gentoo Linux Wiki have useful bits of information, e.g. on WLAN.
- XFCE does not depend on HAL anymore?!
Traps I hit
- Forgot to install DHCP client first time.
- Entered non-ASCII passphrases with wrong keymap activated. No fun.
Odds I came across
"dokeymap keymap=de" boot options are not documented LUKS="yes" genkernel config is not documented
- Without "export TERM=linux" not even
htopworks on a Xubuntu 10.10 live. No, really.
gentoo-sourcesis licensed under the "freedist" license?
Kernel module auto-loading does not work here. Still need to figure out why.EDIT: The line
/etc/conf.d/modulesdid the trick. As the installation handbook only covers baselayout-1.x, that's sadly not documented.

Some packages in Gentoo support being installed for several Python versions at
the same time. One of these packages is
dev-python/pyinotify. If you look at
the ebuild (file
you stumble upon these lines:
PYTHON_DEPEND="*:2.5" SUPPORT_PYTHON_ABIS="1" RESTRICT_PYTHON_ABIS="2.4"
These lines tell that pyinotify 0.9.1 is expected to handle Python 2.5, 2.6,
2.7 and 3.0, 3.1, and 3.2. They are discussed in detail in the
Gentoo Python Developers Guide.
When installing pyinotify 0.9.1 with no
USE_PYTHON line in
by default you will get files for the active version of Python 2.x and Python
3.x. This line of the python eclass (file
There is three different active versions of python in Gentoo: one active version for 2.x and 3.x and third, a main active version from either pool, 2.6 in my case. These commands are meant to illustrate this:
# eselect python list --python2 Available Python 2 interpreters:  python2.6 *  python2.7 # eselect python list --python3 Available Python 3 interpreters:  python3.1 * # eselect python list Available Python interpreters:  python2.6 *  python2.7  python3.1
So with no specification of
/etc/make.conf I would get
pyinotify installed for Python 2.6 and python 3.1. As I want to have support
for Python 2.7 too, I have this line in my
USE_PYTHON="2.6 2.7 3.1"
This is what it gets me:
# equery f dev-python/pyinotify | grep site-packages /usr/lib64/python2.6/site-packages /usr/lib64/python2.6/site-packages/pyinotify-0.9.1-py2.6.egg-info /usr/lib64/python2.6/site-packages/pyinotify.py /usr/lib64/python2.7/site-packages /usr/lib64/python2.7/site-packages/pyinotify-0.9.1-py2.7.egg-info /usr/lib64/python2.7/site-packages/pyinotify.py /usr/lib64/python3.1/site-packages /usr/lib64/python3.1/site-packages/pyinotify-0.9.1-py3.1.egg-info /usr/lib64/python3.1/site-packages/pyinotify.py
NOTE : After changing
USE_PYTHON, don't forget to run
It will rebuild packages that have too little (or too much) support for Python
in its current form of installation. Besides, did I mention the Python team is
lacking man and woman power?
Inserting an SVG image into an OpenOffice document (.odt) took me more time than I expected. Looking back, this is what worked for me:
- Download SVG import extension (License: LGPL)
- Install the extension (Menu > Tools > Extension Manager)
- Convert to .odg (OpenDocument Drawing) using OpenOffice Draw:
- Open the SVG file
- Save as ODG
- Insert ODG picture into text document (Menu > Insert > Object > OLE Object... > Create from file)
