Ole Albers: Just wanted to tell that the Google+ Optimizer now has a cross post to Diaspora…
Posted by jpluimers on 2018/10/23
Cool: [WayBack] Just wanted to tell that the Google+ Optimizer now has a cross post to Diaspora – Feature…. – Ole Albers – Google+.
Get it from [WayBack] Ghosttown – Optimizer – Chrome Web Store
The Google+ – Optimizer increases the user experience with Google+ until the bitter end…With this extension you can modify and arrange your google+ stream just like you want. Some of the Features: * Remove unwanted content ("suggested contacts, youtube-comments,animated gifs...) * Display additional content (stopwatch) * Filter by Hashtag * Autosave-Feature * Bookmark-Feature ... and more
The first time you open a page on plus.google.com, you see this:
Then when you post a removable information bar:
That directs you to the configuration (either right click the icon, or follow http://hurz.me/gplusoptimizer), where in the main item, you can enter your diaspora host (in my case pluspora) information:

Nieuwere @Samsung_NL TVs gebruiken de OneRemote (soms ook Smart Remote genoemd) model BN59-01241A. Werken op die TVs ook de klassieke remotes zoals BN59-01223A die met oudere TVs werden meegeleverd?

Geen antwoord van Samsung op [WayBack] “Nieuwere @Samsung_NL TVs gebruiken de OneRemote (soms ook Smart Remote genoemd) model BN59-01241A. Werken op die TVs ook de klassieke remotes zoals N59-01223A die met oudere TVs werden meegeleverd?”
Gelukkig kwam ik dit tegen:
[WayBack] Reviews over Samsung UE50MU6100 – Coolblue – alles voor een glimlach
De afstandbediening is wel even wennen in gebruik, maar als je een oude Samsung afstandbediening hebt liggen werkt dit op deze tv en kun je dus de nummertoetsen gebruiken bij het zappen ;)
Later kwam Samsung alsnog met een antwoord:
[WayBack] Samsung Nederland on Twitter: “Hey Jeroen! De ‘normale’ afstandsbediening werkt ook gewoon op de nieuwere modellen! ^Nadia… “
Oh ja: Samsung maakt zowel 49, 50 als 55 inch versies: [WayBack] Comparison between: 49.5″ Samsung UE50MU6100, 48.5″ Samsung UE49MU6100, 54.6″ Samsung UE55MU6100.
Vergelijken in die MU61xxx serie blijft lastig. De 6100 kan meer dan de 6120 (bluetooth en voicecommand). De 6199 kan meer dan de 6179:

Hopefully this is now available: in March you could pre-order the PoE hat for the Raspberry Pi 3 B+ at ~ EUR 15.
Posted by jpluimers on 2018/10/22
Wow, EUR 15 is almost half the price of an Raspberry Pi 3 B+:

Doctors disabled wireless in Dick Cheney’s pacemaker to thwart hacking – Naked Security

Medical devices are still vulnerable, five years after this became public:

wget and curl: downloads that sometimes fail

For my archive somewhere between cURL 7.21.0 and 7.34.0 it does not like to be started from an RDP based tsclient share:

It fails the same way after net use B: \\tsclient\bin, so that does not matter.
The best link I could find until I got to the real problem was [WayBack] curl: (6) Could not resolve host: application – Stack Overflow which shows a different problem: properly quoting.
In addition to remote-name, you can also grab the file name from the headers using --remote-header-name, and --remote-time use the remote file time. The --location follows 302-redirects. You can see that in the example below which I build based on
[WayBack] unix – Curl to grab remote filename after following location – Stack Overflow: The remote side sends the filename using the Content-Disposition header.curl 7.21.2 or newer does this automatically if you specify –remote-header-name / -J.curl -O -J -L $url

Giving up.
This is not caused by the filename (Windows does not like the ? question mark in output file names, so – like & ampersand in file URLs – you have to quote the full URL, but also provide the --restrict-file-names=windows parameter; see [WayBack] wget – I can’t download files with “?” – Super User).

Euler’s identity – cool explanatory videos by Burkard Polster
Posted by jpluimers on 2018/10/19
[WayBack] e^iπ = -1 – Daniela Osterhagen – Google+ reminded me of [WayBack] Euler’s identity (often called the most beautiful formula in the world) and these two great videos by Burkard Polster I bumped into a few years back below.
She points to a German link about “the most beautiful formula in the world”, to which I fully agree:

when btrfs-size shows a snapshot as 16777216.00TB or btrfs qgroup as 16.00EiB
Posted by jpluimers on 2018/10/19
A long time ago I wrote about the btrfs-size tool: [WayBack] A bash script to btrfs snapshot details like disk sizes (requires btrfs quota to be enabled).
One day, it showed a ridiculously large size for /tmp:
# ./btrfs-size.sh
=============================================================================================================================================================================================================================================================
Snapshot / Subvolume ID Total Exclusive Data
=============================================================================================================================================================================================================================================================
257 gen 855182 top level 5 path .snapshots 257 4.30MB 4.30MB
258 gen 856438 top level 257 path .snapshots/1/snapshot 258 1.84GB 193.01MB
...
262 gen 856438 top level 5 path srv 262 1.83GB 1.83GB
263 gen 856438 top level 5 path tmp 263 16777216.00TB16777216.00TB
264 gen 856438 top level 5 path usr/local 264 260.00KB 260.00KB
...
990 gen 849192 top level 257 path .snapshots/583/snapshot 990 1.83GB 8.23MB
991 gen 849224 top level 257 path .snapshots/584/snapshot 991 2.09GB 62.66MB
=============================================================================================================================================================================================================================================================
Exclusive Total: 3.26GB
This tracks back to the output of this command, which I’ve shortened a bit:
# btrfs qgroup show / qgroupid rfer excl -------- ---- ---- 0/5 16.00KiB 16.00KiB 0/257 4.30MiB 4.30MiB ... 0/262 1.83GiB 1.83GiB 0/263 16.00EiB 16.00EiB 0/264 260.00KiB 260.00KiB ... 255/274 0.00B 0.00B 255/797 16.00KiB 16.00KiB
This is a known issue as quotas in btrfs – though workable – aren’t fully stable yet: [WayBack] Linux BTRFS Storage: Re: During a btrfs balance nearly all quotas of the subvolumes became exceeded
It also provides this simple solution:

Some links on encrypting configuration files or sections
Posted by jpluimers on 2018/10/18
All encryption comes down to a combination of key management and tooling.
With more and more communication projects going on, encryption of the secrets (passwords, API keys, etc) in configuration files, especially the ones that might end up in (sometimes public) repositories will need my attention some day.
My gut feeling is that an asymmetric solution might work best for these kinds of problems.
