Links: file I/O into pipe I/O with /dev/fd, Hot Chips RISC-V tute video
by Rodney Brown 06 Jan '20

06 Jan '20

https://www.spinellis.gr/blog/20191214/ Convert file I/O into pipe I/O with /dev/fd Some Unix commands read data from files or write data to files, without offering an obvious way to use them as part of a pipeline. How can you write a program to interact with such a command in a streaming fashion? This would allow your program and the command run concurrently, without the storage and I/O overhead of a temporary file. You could create and use a named pipe, but this is a clunky solution, requiring you to create and destroy a unique underlying file name. Here's a better approach. Modern Unix systems offer a virtual device directory named /dev/fd/. The files in it correspond to the file descriptors of each process. ... https://www.youtube.com/watch?v=nPXdbm9lc3A Hot Chips Tutorial2: RISC-V 2019-08-18 This tutorial provides an introduction to the RISC-V open ISA, the software development ecosystem built around it, and two open-source cores that have been created to use it.

BlueHackers crowd-funding free psychology services at LCA and other conferences
by Arjen Lentz 01 Jan '20

01 Jan '20

Hi all, and a happy new year! BlueHackers has in the past arranged for a free counsellor/psychologist at several conferences (LCA, OSDC). Given the popularity and great reception of this service, we want to make this a regular thing and try to get this service available at every conference possible – well, at least Australian open source and related events. Right now we’re trying to arrange for the service to be available at LCA2020 at the Gold Coast, we have excellent local psychologists already, and the LCA organisers are working on some of the logistical aspects. Meanwhile, we need to get the funds organised. Fortunately this has never been a problem with BlueHackers, people know this is important stuff. We can make a real difference. (BlueHackers hasn’t yet completed its transition from OSDClub project to Linux Australia subcommittee, so this fundraiser is running in my personal name. Well, you know who I (Arjen) am, so I hope you’re ok all with that.) We have a little over a week until LCA2020 starts, let’s make this happen! Thanks. You can donate via MyCause: https://www.mycause.com.au/page/219883/bluehackers-funding-free-psychology-… please donate and help spread the word. https://bluehackers.org/2020/01/01/bluehackers-crowd-funding-free-psycholog… Twitter @BlueHackersOrg Regards, Arjen.

Anyone know Asterisk?
by Andrew Pam 30 Dec '19

30 Dec '19

I have a client running their business telephony using Asterisk on a Gentoo Linux server, and they need to change providers because their old provider is going out of business. I have tried to set up a new SIP trunk service on their server and also on a test Asterisk installation I set up on my own Debian system, but I can't get calls to work either inbound or outbound. Anyone out there know how to configure Asterisk? Thanks, Andrew

Bash Recursive File Rename
by Piers 17 Nov '19

17 Nov '19

Hi there, I have a bunch of files that I want to rename: 123.someword.doc > 123.doc 456.someword.pdf > 456.pdf The "someword" is consistent in all the files and they need to be renamed recursively. Something like this but with a different regex: # This is for a completely different file name structure find . -name '123*.txt' -type f -exec bash -c 'mv "$1" "${1/\/123_//}"' -- {} \; ...sorry regex is a shortfall of mine. Thanks in advance. Cheers Piers

I also purchased 2 boxes Verbatim M-disc Bdr 25gb 5pk to use for trials. Both mail-orders arrived recently. I tried the new burner with ordinary DVD using brasero SW. It created small data DVD without any issues. I created 21.2 GiB .iso with brasero also without any issues. When I asked brasero to burn it and presented one M-disc in the burner it responded with "Please replace the disc with a supported CD or DVD". Search results for “M-disc” in brasero help returned: 'No matching help pages found in “Brasero Help”. I also tried k3b with the same .iso. It asked for a disc, played a bit with inserted M-disc and then stopped, still asking for "an empty Blu-Ray medium" So far no success but also no coaster... Any advice what to try next would be appreciated.

Hardware library

I just gave one of each item that's duplicated in the hardware library to kick-start another hardware library (reproducing like amoeba). After doing that it looks a bit bare. Please consider if there's anything you can donate at the next meeting. -- Sent from my Huawei Mate 9 with K-9 Mail.

DRI
by Russell Coker 14 Nov '19

14 Nov '19

Is there any way to disable DRI for an application? Kmail is using DRI and SEGVing in the Nouveau libraries. Not sure how much of this is Kmail bugs and how much is Nouveau (valgrind reports heaps of issues in Kmail and Nouveau triggers kernel bugs). But while investigating this I'd like to have Kmail keep working while not removing DRI entirely from the system. Any suggestions? -- Sent from my Huawei Mate 9 with K-9 Mail.
