https://docs.mailman3.org/en/latest/migration.html We currently run Mailman 2 which is not supported in Debian/Bullseye which will freeze soon. So upgrading will force an upgrade to Mailman 3 (which is a good thing anyway), above are the upgrade docs. One thing to note is that URLs for archives will change, is this a problem? https://etbe.coker.com.au/2021/01/12/psi-cgroup2/ I've already started upgrading the LUV server to Debian/Bullseye, the above blog post shows one of the things I'm doing to take advantage of new Linux and systemd features. To get some of these things working well before the freeze of Bullseye I need to have some real servers running the latest code. I would like to get the upgrade done in the next few days. I don't anticipate this causing any inconvenience as the lists have been very quiet recently. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

RISCV: RV64 K210 & up, RV32 at espressif

by Rodney Brown

https://riscv.org/exchange/ Board list - has the BeagleV specs, lists a number of K210 boards The Canaan Kendryte K210 dual-core RV64 SOC lacks a Linux compatable MMU, so requires FDPIC to use shared libraries. https://lca2020.linux.org.au/schedule/presentation/203/ RISC-V FDPIC/NOMMU toolchain/runtime support Linux has been ported to the K210 and it is actively developed if you want a comparatively cheap RV64 linux device. 400MHz dual-core 64-bit is more than my first 486-DX2 66MHz box - might have been 8MB of memory like the K210. It may have predated ELF binaries on linux. So I should build Linux for mine. http://lists.infradead.org/pipermail/linux-riscv/2021-January/004161.html RISC-V Kendryte K210 support improvements Announcement of a single core Linux capable RV64 chip https://www.cnx-software.com/2020/11/09/xuantie-c906-based-allwinner-risc-v… https://occ.t-head.cn/vendor/cpu/index?id=3817197695983423488 USD150 8Gb Dual Core RV64 - HiFive https://arstechnica.com/gadgets/2021/01/seeed-and-beagleboard-team-up-to-pr… https://beaglev.seeed.cc/ Scroll down for specs RV32 - I haven't seen mention of Linux capable RV32 boards and am not sure if the port is complete. https://www.espressif.com/en/support/documents/technical-documents Espessif in it's ESP32-S2 includes an RV32IMC 8Mhz 8kB processor that can be used in deep sleep mode and has announced (leaked?) the ESP32-C3 series as an ESP8266 upgrade path. RV32IMC ISA, up to 160MHz. 384KB ROM, 400KB SRAM, 8KB RTC Memory (works in Deep-Sleep mode) 4 Kbit of efuse I'd guess the ESP32-C3 micropython version would have a lot more headroom. It would be interesting to see what the ROM will have.

Ramme install - Instagram Client - issue Segmentation Fault

by Andrew Greig

Hi All, I had Ramme installed by Deb on Ubuntu 18.04LTS and it worked quite well with occasional flakiness, but no hanging the computer. I have upgraded to Ubuntu 20.4 LTS and now Ramme does not fire up. Starting it from the terminal I get only "Segmentation Fault". At least with Ramme, I was able to upload one image at a time to Instagram without having to bare my ass in Bourke St, I did not need to give IG access to my image folders. My trust of FB does not extend very far. Does anyone else use Ramme? What can I do now, I suspect that Ramme is unsupported, despite it being the best IG client in the Linux galaxy.

LUV Wiki vandalism

by Russell Coker

I have restored the LUV Wiki to the backup from 2nd September 2020 because some time after that spammers discovered that due to a configuration error they could create accounts with edit access with no restrictions. I've fixed that configuration error. I noticed the issue when disk space started running low due to the MariaDB database for the Wiki getting increasingly large due to spam. /var/lib/mysql/luv_wiki was 908M before the restore from backup, now it is 50M. Let me know if you made Wiki changes during that time period, I can extract stuff from the backups if needed. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
