This is my first creation using Inkscape and the first SVG I’ve created, period. I’m quite pleased with it, but also sure it can be better. Feel free to suggest improvements or improve it yourself!

unity-2d-shell crashed with SIGSEGV

20. helmikuuta 2012 klo 6.36
Sijainti: Vianhallintajärjestelmät: Launchpad
Avainsanat: Unity

After upgrading Unity to 5.4, the launcher regularly gets stuck on the side despite being set to hide automatically both in Appearance settings and dconf. It does hide initially as it should, but then eventually no longer does and just stays there on top, blocking that part of the app underneath it. It usually then freezes after some time, then crashes and restarts, after which the autohide again works for a while. Before the freeze it does otherwise work save for the autohiding.

This is the report generated from such a crash. I have a feeling the freezing/crashing can be triggered by scrolling the launcher contents (when it’s in the ”stuck” mode).

It should save the shots into your ’Pictures’ directory without launching the GUI now

It should save the shots into your ’Pictures’ directory without launching the GUI now (see Bug #928364). Is that what’s not happening?

Wireless network interfaces’ names: eth1 vs. wlan0

19. helmikuuta 2012 klo 20.42
Sijainti: Vianhallintajärjestelmät: Launchpad

I noticed my laptop’s wireless interface is named eth1, whereas the wireless on a netbook is named wlan0 (both have a wired eth0 in addition to wireless).

I suppose both are set by /etc/udev/rules.d/70-persistent-net.rules:

# PCI device 0x8086:0x1043 (ipw2100)
SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”, ATTR{address}==” (the MAC address) ”, ATTR{dev_id}==”0x0″, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth1″

vs.

# PCI device 0x168c:0x001c (ath5k)
SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”, ATTR{address}==” (the MAC address) ”, ATTR{dev_id}==”0x0″, ATTR{type}==”1″, KERNEL==”wlan*”, NAME=”wlan0″

Is there a reasoning behind calling ipw2100’s interface eth1 and not wlan0? Is there any reason I shouldn’t change the name (by editing 70-persistent-net.rules to name the ipw2100 interface ”wlan0”, to make the two systems more alike)? I’m not sure I’ll actually do that, but was interested in what the difference means from both theoretical and practical points of view.

This is apparently caused by something not in Chromium itself

Avainsanat: Chrome, Chromium, Epiphany, Firefox

This is apparently caused by something not in Chromium itself: it’s not reproducible in a VM running Oneiric, with 17.0.963.26 from ppa:chromium-daily/dev nor with Chrome 17.0.96356. It *is* reproducible in Precise with the latter too, but not reproducible with Firefox nor Epiphany. In Precise with Chromium 17, it’s reproducible with a temporary profile and a guest login also.

Can no longer drop tabs onto tabs area

18. helmikuuta 2012 klo 22.03
Sijainti: Vianhallintajärjestelmät: Launchpad
Avainsanat: Chromium

With Chromium 17, I can no longer drag ’n’ drop tabs to reorganize them in an existing window: the tabs area no longer lets me drop tabs onto it, so each tab I pick up gets a new window when dropped. Dragging the tab from the new window into the old won’t work either (cannot drop the tab into where the tabs area should be).

”Restart services during package upgrades without asking?” fails to honor –yes for apt-get

I left an old netbook to do an ”apt-get -y dist-upgrade” overnight, and when I returned to it the next morning, the upgrades were unfinished because libc upgrade was waiting for me to respond to ”Restart services during package upgrades without asking?”

It looks like the question is prioritized depending on whether the upgrade is done on desktop or not, and if it’s not, the priority is set critical. According to documentation [1], critical is for ”Items that will probably break the system without user intervention.” I don’t think restart-without-asking satisfies that condition.

With both 3.2.0-16 and 3.2.0-17, what I said in #8 still holds

18. helmikuuta 2012 klo 20.04
Sijainti: Vianhallintajärjestelmät: Launchpad
Avainsanat: Linux

With both 3.2.0-16 and 3.2.0-17, what I said in #8 still holds, with -16 and -17 behaving just as -15 did. 3.2.0-17 added something interesting though: booting 3.2.0-17-pae in recovery mode ”breaks” the -pae’s like (non-recovery booting) 3.2.0-14-pae does. To be sure, I tried recovery booting other kernels going back to 3.2.0-14, and couldn’t reproduce this with them (not even with 3.2.0-14-pae!) . Recovery booting 3.2.0-17 non-pae also doesn’t bring it on, it’s just recovery booting 3.2.0-17-pae.

The steps to reproducing this freeze with 3.2.0-17 are:
1. Boot 3.2.0-17-pae in recovery mode.
2. In the recovery menu, select ”root”.
3. From the root prompt, just reboot.
4. Boot 3.2.0-17-pae (normally).

The ”fix” also still holds: just boot a non-pae kernel once, and the pae’s again work.

WordPress != WordPress.com

Köhöm, WordPress != WordPress.com (mikäli ulkopuolisella alustalla jälkimmäiseen viitattiin).

Mutta asiaan: onko tuo looginen captcha yleisessä jakelussa oleva Drupal-lisäosa vai talon sisällä kehitelty? Onko se tehokas? Kiinnostaa, koska se on täysin suomenkielisenä poikkeuksellisen käyttäjäystävällinen.
