OpenSuSE fix “piix4_smbus 0000:00:07.3: SMBus Host Controller not enabled!”

Posted by jpluimers on 2016/11/01

If you see this in journalctl after boot in a VM, then you likely want to disable piix4 smbus device detection:

Jul 07 23:02:47 revue systemd-udevd[507]: maximum number (136) of children reached
...
Jul 07 23:02:47 revue systemd-udevd[507]: maximum number (136) of children reached
Jul 07 23:02:47 revue systemd-udevd[507]: maximum number (136) of children reached
...
Jul 07 23:02:47 revue kernel: piix4_smbus 0000:00:07.3: SMBus Host Controller not enabled!

The solution is to add one line to /etc/modprobe.d/50-blacklist.conf  (well: maybe [WayBack] add a comment line as well):

blacklist i2c_piix4

Comcast: a tool to similate network problems on BSD and Linux – tylertreat/comcast

Posted by jpluimers on 2016/11/01

At first I thought Comcast was a really good joke by Kristian Köhntopp, but it is actually a really cool open source tool with an appropriate name:

Comcast is a tool designed to simulate common network problems like latency, bandwidth restrictions, and dropped/reordered/corrupted packets.

It is written in go and works on BDS and derivatives (including Mac OS X). It could probably made to work on Windows too.

The source is on Github: tylertreat/comcast

Reminder to self: nosudoers changed in Raspbian…

Posted by jpluimers on 2016/10/31

So I won’t forget: trying to make sense of this incomprehensible message (and the update on a Raspberry Pi takes looooooooong and while updating, the file /etc/sudoers.d/010_pi-nopasswd does not exist yet)

20161018+1 reintroduces passwordless sudo for pi user even if previously removed · Issue #6 · RPi-Distro/raspberrypi-sys-mods [WayBack]

raspberrypi-sys-mods (20161018+3) jessie; urgency=medium

  * The 20161018 release has introduced a /etc/sudoers.d/010_pi-nopasswd file.
    - The file is installed even if the "pi ALL=(ALL) NOPASSWD: ALL" entry has been
      previously removed from /etc/sudoers by the user.
    - If you do not want the entry to exist, please comment out or remove 010_pi-nopasswd.
    - If upgrading to 20161018+3 from a version earlier than 20161018, the line in
      010_pi-nopasswd is automatically commented out if the entry doesn't exist in sudoers.
    - See https://github.com/RPi-Distro/raspberrypi-sys-mods/issues/6

Kristian Köhntopp: Let’s have a chat – a taxonomy and some context (history and future; 20160606)

Posted by jpluimers on 2016/10/31

A few months ago was my first ever presence on IRC wich started like this:

[13:45]  bear with me: after BITNET relay chat, I've totally skipped the IRC thing, so
[13:46] * jeroenp_ is IRC n00b and wonders if netiquette is roughly the same as in the mid 1990s (:
[13:46]  jeroenp_: I don't think it changed a lot...
[13:46]  Cool: /me works on IRC too (:
[13:47]  Anyone having time to help me with `zypper dup` on Tumbleweed indicating `python3-urllib3-1.16-1.1.noarch requires python(abi) = 3.5` ?

I will post later on my own chat history (including BITNET Relay conference system on BITNET/EARN).

This post is just to mention a few keywords of Let’s have a chat – a taxonomy and some context(This is a text I wrote for work, but it contains nothing work specific and I might as well drop it here.… – Kristian Köhntopp – Google+

Kristian Köhntopp now basically uses his G+ as a blog (blog.koehntopp.de is now defunct) with a great set of collections.

I’ve kept my blog as I find G+ very hard to search for content and a “bla bla site:wiert.me” for me often is the fastest way to find something back that interests me.

Hence the keywords below on his post Let’s have a chat – a taxonomy and some context.

  • Chat, IRC, ICQ, Jabber, Skype, Google Hangouts, Facebook Messenger, WhatsApp, Slack and RocketChat
  • Google Wave, Apache Wave, Google Documents  and Google Spaces.
  • Managing presence in adverse circumstances: status, /away, nickname renaming
  • Deliverables
  • One identity, many clients: a common history (federation, standards, XML, SIP, extensions, incompatibilities)
  • Many-to-Many conversations: Groups versus Places (rooms, channels, discoverability)
  • Media, bots (hello Eliza) and API
  • emoji, giphy and meme references

How to directly link or embed Dropbox images – via: Canton Becker

Posted by jpluimers on 2016/10/31

When you share a screenshot with Dropbox, then it will copy a URL to the clipboard like this: https://www.dropbox.com/s/mzm7uf775rnjvnv/Screenshot%202015-01-29%2022.25.15.png?dl=0

That is not the actual screenshot. It is a web page around the screenshot that contains a lot of hoopla so you cannot easily copy the download link of the image.

Getting that download link is easy: make the below replacement:

  • ?dl=0
  • ?raw=1

Example: https://www.dropbox.com/s/mzm7uf775rnjvnv/Screenshot%202015-01-29%2022.25.15.png?raw=01

Or embedded:

Letsencrypt and support for Google Chrome “Requiring Certificate Transparency in 2017”

Posted by jpluimers on 2016/10/29

This week there was the very important Google Chrome Announcement: Requiring Certificate Transparency in 2017 – Google Groups [Archive.is].

I’m glad that letsencrypt already submits all certificates to Certificate Transparency logs [WayBack] for X1 and X3 but there is more to it as you can read in How Certificate Transparency Works – Certificate Transparency [WayBack].

So there’s a [Google Chrome] Announcement: Requiring Certificate Transparency in 2017 – Feature Requests – Let’s Encrypt Community Support [WayBack and Archive.is].

Hopefully one or both of these issues see some progress soon:
