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:

More suppliers should include sha hashcodes for their downloads

Posted by jpluimers on 2016/10/28

I’m really glad that more and more suppliers are providing sha hashes for their downloads.

It allows you to verify an already downloaded binary is in fact

For instance, Cisco does this with their Jabber Messaging software. That way I could verify the (when I wrote this) most recent versions were indeed the ones I already had by just clicking on the filename (no need to click on the Download button).

  • Mac:
    • $ shasum -a 512 CiscoJabberMac-11.0.0.216341.zipbd03b0f8542e0244b30601647e991eec74c2e5b358bf68cdf1b4d6f4e62f96fed83f813d0033e696012dc320a80cc96b9c17d5f98250d44b5252c06732c16df5  CiscoJabberMac-11.0.0.216341.zip
  • Windows:
    • $ shasum -a 512 CiscoJabber-Install-ffr.11-0-1.zip
      7335b739498ca365952325931709bae1c0f5916302117b75fc06862d5623a017834ef3f6fafe76feb722dca5618c1e2d11be17e739a59e0b76a3c382f6d9c31b CiscoJabber-Install-ffr.11-0-1.zip

Wow – people still working on Delphi 6 and 7 based code! Got new votes for answer to get rid of empty DDP files

Posted by jpluimers on 2016/10/27

Only Delphi 6 and 7 used DDP files (still a nice concept: diagrams to help understanding your DFM files)

A long time ago, I wrote a stackoverflow answer and later a blog post on how to find and get rid of empty DDP files as both Delphi versions had the habit of creating them:

The blog post was when I helped moving an ancient Delphi project to a more modern Delphi version (due to some personal stuff going on I never finished it) and I never used such old Delphi stuff again.

This week that answer got quite a bunch of upvotes on the stakcoverflow answer which means people are still using Delphi 6 and 7 based code. Who’d ever thought that 15 year old versions would still be used today?
