I updated and saw nothing of interest or worth commenting about. Supposed to be a small change in Nautilus with the side panel. I never noticed what was supposed to be different. Apparently one of the changes is enabled OpenSSL neon extensions that the ARM v7 (Pi2 and later) support. It might be a little quicker for secure web pages and other stuff that uses it.

Greetings, For those that ran SETI on Raspberry Pi(s), here's something you can assign one of them to do when no longer doing SETI: https://pimylifeup.com/raspberry-pi-pi-hole/ I have Pi-Hole installed and running on my Pi-3 and it is doing the DNS work and blocking shady places on the Internet. My router is set to look at the Pi for the DNS and all other devices go through the router going through the Pi DNS. I did not have to change the DNS lookup on each device, too much work. I updated/upgraded the OS on the Pi first. Installing the Pi-Hole software takes a bit of time and at one point it looks like it is doing nothing for several minutes, but it is. The link above has full instructions (except for the OS update/upgrade) on installing and configuring Pi-Hole. It works as "advertised"! :) Enjoy and have a great day! :) Siran CAPT Siran d'Vel'nahr - L L & P _\\// Winders 11 OS? "What a piece of junk!" - L.

Two fun latest snippets for the Raspberry Pi: Ubuntu 20.10 'Groovy Gorilla' Swings Onto Raspberry Pi That article nicely includes instructions for installing onto and running from an SSD. And for gamers and graphics fiends: The Raspberry Pi 4 Vulcan Driver Is Getting Closer wrote: ... According to the new announcement, the Raspberry Pi 4 Vulkan driver is officially part of the open-source collection of Mesa [graphics] drivers. Mesa [also] provides implementations of other APIs, like OpenGL, OpenGL ES and OpenCL. Happy crunchin'!

Looks like the "chip shortage" is even affecting most if not all Raspberry pi models for sale. https://www.theregister.com/2021/08/20/raspberry_pi_supply_eben_upton_interview/ |

It did not turn out too good... Man spends $5,000 on a 48TB Raspberry Pi storage server Best quote; "All RAID levels (including RAIDZ1) basically maxed out the Pi's bus on sequential reads," said Geerling, who added that the Sabrent NVMe drive was bottlenecked, only seeing "a few hundred megabytes per second of throughput in the best case." |

I'm playing with a new RPi4 4GB model and the latest Ubuntu 21.10 distro. Bought a kit with everything in it from Walmart, case, heat sinks, fan, cables, USB-C power supply with inline switch and preloaded memory card. Snapped together in 5 minutes and booted to Desktop. Pretty cool. Seti@Home classic workunits:20,676 CPU time:74,226 hours   A proud member of the OFA (Old Farts Association) |

I'm playing with a new RPi4 4GB model and the latest Ubuntu 21.10 distro. Bought a kit with everything in it from Walmart, case, heat sinks, fan, cables, USB-C power supply with inline switch and preloaded memory card. Snapped together in 5 minutes and booted to Desktop. Pretty cool. 1. How much did it cost? Here's a list of components for 4GB Pi 4 which totals to $112 plus tax and shipping. I would spend the extra $20 for the 8GB. There' s how tos for installing and running on the USB 3.1 SSD Raspberry Pi 4 4GB $55 https://www.canakit.com/raspberry-pi-4-4gb.html USB-C Power Supply $9.95 https://www.canakit.com/raspberry-pi-4-power-supply.html SanDisk 32 GB micro SD card $8.39 https://www.amazon.com/SanDisk-Ultra-UHS-I-Memory-Adapter/dp/B00M55C0NS Case with excellent cooling $14.49 https://www.amazon.com/Raspberry-Armor-Metal-Aluminium-Heatsink/dp/B07VWM4J4L 60 GB USB3.1 SSD $23.99 https://www.amazon.com/JOIOT-Portable-External-Windows-Mackbook/dp/B08ZHQKT7G Raspberry Pi 4 8GB $75 https://www.canakit.com/raspberry-pi-4-4gb.html 2. Could it easily be connected to BoincTasks, and also VNC, from Windows? Sure. Just add the allow_remote_rpc option to the cc_config.xml get password from gui_rpc_auth.cfg (or set to any password you like) to connect using BoincTasks. For remote desktop I installed xrdp and use Windows Remote Desktop client to remote into the Pi 4. https://raspberrypi.stackexchange.com/questions/118034/directly-install-raspberry-pi-os-64-bit-on-ssd-what-are-prerequisites https://tutorials-raspberrypi.com/raspberry-pi-set-up-usb-boot-using-a-stick-or-ssd-hard-drive/ https://raspberryexpert.com/raspberry-pi-remote-desktop/ |

Bought a kit with everything in it from Walmart, case, heat sinks, fan, cables, USB-C power supply with inline switch and preloaded memory card. Snapped together in 5 minutes and booted to Desktop. Pretty cool. 1) It was $90 +tax but under $100 overall. https://www.walmart.com/ip/LABISTS-Raspberry-Pi-4-4GB-Complete-Starter-PRO-Kit-for-Computer-Programming-Beginner-32GB-Card/910738787 2) I assume it would be just as easy to connect to BoincTasks in Windows. Find Computer on the network from BT menu and connect. 2a) Run raspi-config and turn on the VNC server. Connect to it with your favorite VNC client. 3) See the price has gone up though. About the same now for a complete kit from all the other normal Pi vendors and why I realized it was a steal at $89.99. The power supply alone normally runs $10 and a 32GB U1 micro SDCard even in bulk 10 pack costs $4-6. Cases normally run $20-30. The 4GB Pi4 normally sells for around $55.

Worth it for the ARM72 cores speedup over the ARM57 cores in my Nvidia Jetson Nano 4GB unit. Shaved 10K seconds off my TN-Grid times. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

Seaberry carrier board turns a Raspberry Pi into a desktop PC with 11 PCIe slots Don't get your hopes too high too soon, though. Although the Seaberry board lets you build a desktop PC using off-the-shelf components, as blogger Jeff Geerling describes, at $435 (about £325), it's nearly 10 times the price of a cheap x86 Mini-ITX motherboard. Yes, you'll still have to add an Intel or AMD chip – but then a top-end Compute Module 4 with Wi-Fi, 32GB of eMMC and 8GB of RAM will set you back £85 anyway. |
