Apple has told developers that it plans to delay enforcement of a controversial change in iOS 14 that would upend how ads are targeted on its devices, sources tell me. This is the same change that Facebook warned would impact its ad targeting last week.
Ist Apple nun endgültig zur dunklen Seite der Macht übergelaufen?
There are many theories about this logo and many of them are just that. Find out the truth, read the interview with Rob Janoff, the designer of the original Apple logo, who will tell you all about his design.
Sehr genial ist auch die Vorgabe von Steve Jobs: “Don’t make it cute.”
Hier ein paar Hintergründe von Arun Venkatesan zu seinem „Wochenendprojekt“ – ich wünschte ich würde so was tolles an einem Wochenende hinbekommen.
Sorry for the clickbaity title. But after many failed attempts and many non-functioning tutorials I thought I may be eligible for some exaggeration.
Without further ado – let’s jump directly into the ingredients it needed for me, to make my Raspi 4 boot from SSD. Oh btw, all links are NO affiliate links so please buy the stuff where ever you want.
(You may ask why do you may need this list – well I bought some SSDs and enclosures that unfortunately didn’t work. James A. Chamber has a list of known working adapters and chipsets. So to prevent you from doing the same mistakes, here are my parts that worked for me. You milage may vary and don’t at me, if things don’t work for you.)
Some final remarks: Everything computery was done on a Mac and if you wonder: I am by no means a Linux or Raspbian pro. So if some parts are old cheese for you just jump over them but don’t blame me if things don’t work for you. Also: this guide was inspired by this German article (which is unfortunately behind a pay-wall), which took me 80% of the way, but since some parts were missing, I added them to my guide. Let’s go.
sudo touch /Volumes/boot/ssh – this produces an empty file on the microSDXC card with the file name “ssh” which enables SSH once the Pi has booted.sudo vi /Volumes/boot/cmdline.txt in the Terminal. This opens the file “cmdline.txt” in the editor vi (if you prefer nano, be my guest). On the first line jumpt to the end by pressing “$” followed by the letter “i” which enterst the “insert” mode. Add at the very end of the first line ip=192.168.83.216 – don’t forget the space and of course pls. take your personal fixed IP number. Now press “Esc” to leave the “insert” mode and enter :wq followed by a press of the return key. This writes the file to the microSDXC card and quits the editor vi.Time for some relaxation: now we do some hardware tinkering.
Ideally your whole setup should start-up as indicated by a lot of flickering of the LEDs on the Raspberry Pi and on the UGREEN SSD M.2 NVMe enclosure. If the LED flickering becomes less hectic you may try to ping your Raspberry Pi from your Mac by entering this command in the Terminal app: ping 192.168.83.216 – of course you should use your personal private IP number. If the ping command answers with something like 64 bytes from 192.168.83.216: icmp_seq=1 ttl=64 time=0.278 ms everything is fine. Something like Request timeout for icmp_seq 0 or No route to host is not. If you can’t ping your Raspberry Pi it is hard to diagnose since it could be hardware or software related. Try to ping your router address for example or attach your Pi to a monitor to look for some obscure error messages. If you are pinging successfully to your Pi stop it by pressing control+c simultaneously and proceed to the next step.
ssh pi@192.168.83.216 – again, pls. use your personal private IP number.raspberrysudo apt update and sudo apt install rpi-eeprom-images – the latter one will ask you if you are sure and how much disk space it will cost you. Simply type the letter “Y”.sudo sed -ie s/critical/stable/ /etc/default/rpi-eeprom-update and sudo rpi-eeprom-update -d -f /lib/firmware/raspberrypi/bootloader/stable/pieeprom-2020-06-15.binsudo reboot.sda – this could be done with the command lsblk. The second line of the output should be “sda”.wget https://downloads.raspberrypi.org/raspios_full_armhf_latestmv raspios_full_armhf_latest raspios_full_armhf_latest.zipunzip raspios_full_armhf_latest.zip and throw it away rm -f raspios_full_armhf_latest.zipsudo dd of=/dev/sda < 2020-05-27-raspios-buster-full-armhf.img and also throw the image away rm -f 2020-05-27-raspios-buster-full-armhf.imgIf you are cautious then keep the image around. Maybe later in the process everything goes south and you will be happy to still have the image around.
The next hurdle is that the freshly installed boot loader is not capable of booting from an external SSD – hurray. Therefore we need to swap the boot files with an actual version from the Github repo. Let’s move on:
wget https://github.com/raspberrypi/firmware/archive/master.zipunzip master.zipsudo mkdir /media/pi and sudo mount /dev/sda1 /media/pi/sudo cp firmware-master/boot/*.elf firmware-master/boot/*.dat /media/pisudo shutdown -h nowNo we may remove the microSDXC card from the Raspberry Pi and add two missing pieces on the SSD. Therefor you need to connect the SSD to you Mac and redo the following two commands in the Terminal app:
sudo touch /Volumes/boot/ssh – this produces an empty file on the SSD with the file name “ssh” which enables SSH once the Pi has booted.sudo vi /Volumes/boot/cmdline.txt in the Terminal. This opens the file “cmdline.txt” in the editor vi (if you prefer nano, be my guest). On the first line jumpt to the end by pressing “$” followed by the letter “i” which enterst the “insert” mode. Add at the very end of the first line ip=192.168.83.216 – don’t forget the space and of course pls. take your personal fixed IP number. Now press “Esc” to leave the “insert” mode and enter :wq followed by a press of the return key. This writes the file to the SSD and quits the editor vi.If you would like to benchmark your new setup James A. Chambers has you covered. Scroll down on his article and see the necessary commands after the headline “Benchmarking Your Own Device”.
In general I don’t like to infuse a bunch of software on my installation like with the benchmark scripts above but from an educational standpoint it might be interesting to see how your Pi’s SSD performs.
Aerial is a Mac screensaver based on the new Apple TV screensaver that displays the Aerial movies Apple shot over New York, San Francisco, Hawaii, China, etc. Starting with version 2.0.0, it also includes 3rd party videos that were donated to the project!
Und das sind die Neuerungen:
Without spending $100s of dollars on vintage networking cards I did happen to have a Raspberry Pi kicking around. The other nice thing about using the Pi was it essentially gives me wireless internet on the old Mac, so I don’t have to be tethered to an Ethernet jack.
At risk of over-simplifying things, the Raspberry Pi shares it’s internet connection over a serial cable. The Mac connects with PPP over the serial cable and the Pi has a PPP sever running called SLiRP.
Wenn ich mal wieder Zeit haben, werde ich das definitiv ausprobieren. Jetzt freue ich mich aber erst einmal, dass mein Raspberry Pi 4 von SSD bootet. Dazu gibt es demnächst ein Tutorial auf diesem Kanal – versprochen.
Hat seinen Raspi 4 zum ersten Mal erfolgreich von SSD gebootet – nach gefühlten zwei Dutzend Versuchen und nach zig nicht funktionierenden Anleitungen #puh
Gedankenspiel: Wenn macOS Big Sur so buggy wie Catalina wird, sollte man sich dann Apple Silicon erst mal schenken und einen iMac Pro holen, der noch Mojave kann? Frage für einen Freund, der auch kein Geld hat.
As they learned their way around the system, they explained what they wanted to do, at least in broad strokes. They had added special hardware to the iPod, which generated data they wanted to record secretly. They were careful to make sure I never saw the hardware, and I never did.
Was für eine geniale Story – fast schon krimireif. Kommt demnächst bestimmt auf Apple TV+.
The last batch of photos from a hike with reduced participants – Audrey got a cold and returned early with my wife Sabine. So I proceeded with my younger daughter Donna to the Alp Garfiun from Klosters and back. At the Alp (after some delicious Älplermagronen and salad) a huge storm was approaching and escorted us the whole way back. Later tons of rain and thunderstorms joined but luckily we were already at home. On Tuesday Donna went home to Munich by train and we drove by the power of the sun on Wednesday back to Düsseldorf.
