Raspberry Pi: Time sync

When I tried to do a regular update on a Raspberry Pi 1 with sudo apt-get update, I got this error message:

E: Release file for http://raspbian.raspberrypi.org/raspbian/dists/buster/InRelease is not valid yet (invalid for another 1d 14h 44min 54s). Updates for this repository will not be applied.

Checking the date I saw that the Pi was not in sync with time. Adjusting the date is easy:

$ sudo timedatectl set-time "2019-11-09 21:25:00"

and now it worked again. Thanks Patric Fromaget / raspberrytips.com for the solution I found with a quick web search.

MacBook Pro: full resolution

A fresh MacBook Pro 15″ 2017 with MacOS High Sierra. However, the cool resolution of 2880*1800 is not available to the mere user, even with usage of holding the option key.

Found the tool RDM which enables all those resolutions for me to choose.

Now on to testing responsive design with 5k resolution.

Needs update: gfxCardStatus

gfxCardStatus is used to manually switch between integrated and discrete graphic cards on the MacBook Pro. My 2011 model had some issues in the past (before fixed by Apple) and I prefer turning off the discrete graphics card if not required. The app does this automatically (f.ex. no external monitor at work).

After using gfxCardStatus for quite some years, the app seemed to stop working after my latest OSX update run. As the latest version 2.3 by CodyKrieger has not been updated for years. However, steveschow updated and optimised it and that version works with OSX High Sierra.

Reactivate old RasPi

As my first Raspberry Pi catched some dust I found a new project involving it.
Researching current procedures regarding backup old image and add new image to the SD Card, here it is:

Backup

  • Putting the SD Card in my reader in my Mac
  • Utilities > Disk Utility
  • File > New Image from boot
  • Choose as type CD/DVD image and save it

New Image

The really cool and minimalistic tool Etcher is suggested by the RasPi homepage.
I chose the current Raspbian 9 to be put on the SD Card by Etcher.

Etcher in use

Once the copy/install process was finished I opened a terminal session, navigated to /Volumes/boot and used touch ssh.

This will enable ssh on the RasPi, directly enabling it to be contacted by a terminal session instead of putting a usb keyboard on it.

  • User: pi
  • Password: raspberry

Any changes can be done with sudo rasps-config – especially password and network name of system

Now the old RasPi can be used again, this time without extra ac plug but on the new Bestek Steckdosenturm.

Netgear GS716T v3: Firmware update to V6.3.1.19

After one and a half year with the Netgear GS716T v3 I’m still pleased. A bit late as the update is around for a while I updated the switch as some bugs were fixed.
Over here you find the download.

You find in this previous article how I did it: Netgear GS716T v3: update Firmware

2018-06-19 Update: for our convenience the general download link to GS716T v3.

Cube update: Crucial MX300

Trotz des Vorsatzes, zu Black Friday nichts zu bestellen, habe ich ein um 60€ günstigeres Angebot genutzt, um den Cube Server mit Crucial MX300 SSDs je 750GB aufzurüsten.

Im bereits vorher gekauften Gehäuse ICY Dock MB996SP-6SB wird der Platz jetzt eng. Insgesamt passen 6x 2,5″ Platten in das 5 1/4″-Gehäuse. Wie schon die Samsung 850 EVO lassen sich die noch flacheren Crucials gut auf die Metallschinen schrauben und sitzen fest.

RAIDZ aus SSDs

Mit den neuen Crucials richte ich mir endlich ein RAIDZ aus SSDs ein und verschiebe die bestehenden VM Images direkt auf den schnellen Storage.

Lightroom editing with Midi: Behringer X-Touch Mini

To improve my Adobe Lightroom workflow I plan to use the Behringer X-Touch Mini to edit pictures faster and focusing on the tools in photo edit view.

Some reviewers suggest to use MIDI2LR, however I’m still with Lightroom 4. Let’s see if it works, otherwise the first good reason to go after current version 6.

This post will be updated once I got the X-Touch Mini.
