Here’s my take on how "Mesh: Compacting Memory Management for C/C Applications" relates to GSlice:

GSlice considerations and possible improvements

Beast version 0.13.0 is released.

Beast is an LGPLv2+ music synthesizer, composer and #DAW (Digital Audio Workstation).

It provides a #MIDI #sequencer, unlimited undo, real-time #synthesis, support for Linux #Audio Plugins (#LADSPA v1), Soundfont 2, WAV, AIFF, Vorbis, Gus Patch, FLAC and MP3 files, 32bit audio rendering, full duplex support, multi-core audio rendering and precise timing.

This release features a prebuilt binary (AppImage) for the first time.

Just fixed a potential memory corruption bug detected by #scan-build (delete/free mismatch).

If your project compiles with #clang/clang++, invocation can be as easy as:

$ scan-build make

There may be lots of output generated, but catching bugs like the above *before* it's actually triggered make it really worthwhile to plow through the warnings.

#bugfix

I'd love to learn what others are using instead of #libtool.

TL;DR
Replacing libtool has been the major hurdle for me for replacing #autotools, and long term I want to get rid of both.

Finally someone to talk to when you're bored ;-)

Just chairs, #35c3

Easy to make giant friends at #35c3

After a lengthy Autobahn trip, I have arrived at Leipzig for #35c3.

Toot me if you're interested in a meetup at #ccc, or ask for timj at the #cbase assembly.

It turns out that https://rawgit.com/ is about to shutdown (being just a hobby project after all), but jsDelivr stepped up to provide the same functionality now.

So the previously posted #CSS snippet for using the CharisSIL5 webfont now becomes:

@import url('https://cdn.jsdelivr.net/gh/tim-janik/assets@a8a12dd652e48532faa39657bc5cc268525a89ca/CharisSIL5/CharisSIL-webfont.css');

html { font-family: "CharisSILW", serif; }

The #cdn behind jsDelivr is cloudflare and the content is served with a Cache-Control max-age of 365 days.

I just ran across the blog of André Staltz, Scuttlebutt author and creator of manyver.se/. He's got lots of thoughtful and interesting articles, excerpt:

> And [...] an internet experience that violates my privacy, profits behind my back, silences my voice, steals my attention for ads, and forces me to read and accept regulation banners, [is not] a good enough sales pitch.

Wow, a declarative cross-browser crash, purely in #CSS.

Have been chasing a #Beast build bug on #Fedora 28 for several days now.

Turns out it's actually a #gcc 8 regression, the one thing I usually expect to be least likely:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87748

So with #Google closing down G+ and the new Birdsite terms (that I've never accepted so I can't login to my account anymore), I've started asking my remaining contacts to consider moving to #Mastodon.

Interestingly enough, the non-conglomerate, non-monopoly, but community powered and decentralized technologies have started to look a lot more robust, attractive and reliable than the rest in recent years.

It must be 2 or 3 weeks now that I've been working on
a) static code checks for Beast;
b) making libbse fully relocatable to build an AppImage.

Travis-ci has finally completed the newest builds which produces a single .x64 executable for Beast, reports from cppcheck, scan-build and clang-tidy.

It all gets built from a single Dockerfile and is automatically uploaded to a bintray file area:

https://bintray.com/beast-team/nightly/beast

Today's lessons learned from debugging an evasive CI segfault:

- Docker run needs --cap-add=SYS_PTRACE to support gdb.
- Docker stack size is limited to 8MB by default.
- A clang++ compiled program may need vastly more stack space than a g++ compiled one.
- A clang++ -O1 compiled program using 6MB stack size may need around 12MB if compiled with -O2.

When I got up this morning, I would have expected none of these points to be true.

Just figured it is really easy to setup and test a #Nextcloud instance with #docker:

docker pull nextcloud
docker run -p 8080:80 nextcloud
firefox http://localhost:8080/

Also the Android "nextcloud" app is easily installed and can be pointed to the dockerized nextcloud instance if you know what the hostname or IP of "localhost" is in the local WLAN.
