I’ve fixed matching of IPv6 addresses in sysutils/pflogsumm and also updated it to version 1.1.5 in pkgsrc. Note that the naming of options has changed from using underscores to using hyphens.
I fished out a couple of upstream commits (patch #1 and patch #2) for net/mtr to silence the Error decoding localhost address messages.
I applied a small patch to mail/postgrey to silence an error about the PID file when stopping the service.
I fished out an upstream commit to graphics/gd to address CVE-2018-1000222. While there, I also restored the option to make linking with libtiff optional.

Network speed and IRQ affinity

Written at evening time in English • Tags: , ,

By default many Linux network interface card drivers set their SMP affinity mask to either all zeroes or all ones (“ff” — the length of the mask depends on the number of CPUs on the system). The former results in all queues and interfaces running on CPU ID 0, which can become a performance bottleneck due to insufficient computing power. The latter results in all queues and interfaces being scheduled on multiple CPUs, which can become a performance bottleneck due to increased CPU memory cache misses. (more…)

Skype settings

Written in the mid-afternoon in English • Tags: ,

For whatever reason my Windows desktop profile is not reflected to my Citrix apps. So I get to figure out the settings that I’ve changed over the years all over again.

In Skype for Business I want a fixed width font and no emoji.

  • Click the Settings menu in the main Skype window (the cog icon).
  • Select IM on the left.
  • Uncheck the box for Show emoticons in messages.
  • Click the Change Font button and choose Consolas.

Alexa, what time is it?

Written early in the morning in English • Tags: ,

This morning Alexa was an hour behind — she hadn’t moved to DST. A quick search on Google showed that last year DST switching had worked.

The top hit, however, was a fresh Reddit thread with Alexa users reporting the same issue. After keeping an eye on it, I saw a user come up with the solution that worked for me (and it is the only solution on the thread so far).

Launch the Alex app and go to Settings, select a device, and change the timezone

  • from America/Eastern Standard Time
  • to US/Eastern Standard Time

The fix takes immediately: just ask “Alexa, what time is it?” — no power cycling needed.

Uncloudable photos

Written early in the evening in English • Tags: , ,

Since switching to the iCloud Photo Library, the Photos app on my laptop has kept telling me that

  • 1 Item on This Mac Only
  • Unable to Upload 9 Items

To identify the oddball photos, I created the following smart folders respectively:

  • [Photo] [is] [referenced]
  • [Photo] [is] [unable to upload to iCloud Photo Library]

Referenced photos can be consolidated into the library and would then be uploaded to iCloud — mine was a duplicate, so I just deleted it. The photos that could not be uploaded were photos that had been deleted, but somehow a reference had been kept or imported.


Switch back to sysvinit

Written at lunch time in English • Tags: , , ,

If you have already upgraded to jessie and have systemd as init, you can switch back with these commands:

apt-get install -y sysvinit-core
apt-get purge -y systemd

Running with sysvinit works better on my servers, as daemons have a chance of doing their own graceful shutdown before the network is brought down.
