The DragonFly 4.4.3 point release is out. There’s a commit page listing the changes between 4.4.2 and 4.4.3. Nobody will be surprised that there’s an OpenSSL update in there.
If you want a complete image, it’s available for download at your nearest mirror. If you want to upgrade an existing install:
cd /usr; make src-update
(or src-create-shallow if you don't already have source)
make buildworld && make buildkernel
make installkernel && make installworld
I’d save this for an In Other BSDs note, but that’s a whole week away: FreeBSD Mastery: Advanced ZFS is published, available in electronic and printed editions. I suspect this would be interesting to non-BSD users, too.
I’m studying for a test next week, so the amount of random clicking-around that I’ve been able to do has been limited.
Your off-topic pen link of the week: Remember I asked once about decent fountain pens that were not expensive? I found one, and it’s great.
This is one of those weeks where a bunch of release all tumble together by chance.
Garbage number 22 is out, and talks about a number of things, including NVMe support in OpenBSD, programming in Go, and ‘reader-submitted issues’.
No interview this week on BSDNow because of travel, but there’s still an episode, complete with news and an unboxing video of a new BSD product. I’m linking to a slightly different location because it’s not up on the normal site as of this writing.
Tomohiro Kusumi would like to port Hammer (1) to FreeBSD, as noted in this bug discussion. It’s not even begun to happen, but if you can contribute, please do.
I’ve finally used up my Lazy Reading links backlog!
Your sort-of off-topic link of the week: Michael W. Lucas’s fiction is, for a short time, part of a larger book bundle which is available for less than the price of buying it all individually. Buy now if you want a deal/lots of fiction to read.
This week’s garbage podcast is out, with some OpenBSD topics and also some interesting direct experience of licensing violations.
The GNN in the title is George Neville-Neil, interviewed on BSDNow 136 about the TeachBSD project, plus the usual collection of recent BSD news. The show title comes from this station advert.
Posting now so people have warning: NYCBUG’s monthly meeting is tomorrow, April 6th, and has John Wolfe presenting “Debugging with LLVM”. Note that the meeting announcement I just linked has the NYCBUG schedule and speakers for the rest of the calendar year. Surely you can make one of them?
Tomohiro Kusumi has been creating a near-constant stream of bugfixes and cleanups to Hammer for quite some time. I don’t often link to it, because they are incremental improvements and hard to linkblog, so to speak. In an effort to make up for this deficit, I do want to draw attention to his two recent commits: “Make hammer commands print root volume path“, and “Print volume list after volume-add|del“. Small changes, but this is what makes complex systems usable.
If you remember this Baytrail problem, Daniel Bilik has gone and found a fix, as this appears to be a cross-platform bug, and he has patches for DragonFly. If it’s affecting you, you don’t have to wait for the patches to be added in; he’s made them available directly.
Update: it’s committed to DragonFly now.
This I all built up over the past two weeks, so plenty to read here.
I’m a bit short this week, but I’ve been on the road and unable to click around as much as I’d like.
The 20th garbage episode, justing by the summary, talks a lot about the new OpenBSD 5.9 release and other BSD-related matters.
I keep posting about Sepherosa Ziehau’s work on sustaining extremely high traffic loads in DragonFly. Now I’m posting about a tool to create that load: kq_sendrecv. It creates tens of thousands of TCP connections, without creating a process for each, and uses kqueue, as you might guess from the name. This may be useful if you really want to tax another system.
This week’s BSDNow has an interview with Michael W. Lucas, BSD author. He often speaks at events, so it should be an enjoyable talk.
Do you have a Cherry Trail SoC? For example, a HP x2 210? Imre Vadasz’s recent commit may be useful for you, if you are running DragonFly on this detachable … thing?
Tim Darby is looking for motherboard recommendations. Specifically, mini-ITX with 4 SATA ports and at least one decent network link. Who’s got hardware to recommend? There’s already one set of suggestions.
Normally I would save this for a “In Other BSDs” weekend edition, but it would be too late: if you want to get in on a book sponsorship for Michael W. Lucas’s next FreeBSD Mastery book, you have only a few days left to join in. His last book sponsorship worked out perfectly, timing-wise.
This is actually overflow completely from previous weeks. I am not sure how I am ending up so far ahead on these but not the Saturday BSD items. As long as it shows up on the expected day, I suppose it works out.
Your kinda-unrelated item for the week: Butterfly Stomp, Michael W. Lucas’s free short story. He writes fiction when he’s not writing BSD books.
By the time you read this, I will have already been at my second job for 5 hours.
This week’s garbage podcast is up, to go with the BSDTalk interview, and they’ve made it to 20 episodes. There’s a section at the end about cross-pollination (my favorite BSD term) which I have not been able to listen to yet, but I’m curious.
It’s zero-indexed, if that made you confused for a second.
Update: I listened, and the cross-pollination conversation matches my impressions too. Decentralized leadership is a cause, I think.
BSDTalk 263 has a 17 minute interview with joshua stein and Brandon Mercer, who create the at-least-partially-BSD-themed garbage.fm podcast. It’s a podcast about podcasters!
BSDNow 134 is out, with a news roundup and an interview of Mark Felder, talking about FreeBSD ports.
(Which may extend to DragonFly, indirectly, through dports; I haven’t listened yet.)
If you have a Radeon video card in your DragonFly system, and are running bleeding-edge, there’s an update for you. This is a partial sync with Radeon code for Linux 3.18, with no additional notes in the commit but you can always check elsewhere.
unzip has been added to DragonFly, making it present in every BSD but I think OpenBSD.
Imre Vadasz has added the ability to create a UEFI bootloader in DragonFly. Can you use it? I don’t know; I haven’t tried it yet and I can’t tell from the commit.
John Marino has added the starting framework to use clang as the alternate base compiler in DragonFly. Note that it’s not hooked into the build yet. This is the first non-GCC compiler added into DragonFly, so there’s some work yet before you can have an all-clang system. This should replace GCC 4.7, which is the current alternate compiler. GCC 5.0 is the default, if you didn’t know.
Note that clang is present in dports, so it’s already been available for general use, for some time. This framework is for building DragonFly itself.
I’m sort of proud of how wide a range of topics are covered this week.
Garbage 18 is out, and talks about the hardware in the title – and also goes into tethering between Android and OpenBSD, which I am sure someone will find immediately useful.
If you somehow have a device with multiple SD/MMC card slots, you can now access all of them under DragonFly. (Apparently done to make a tablet run DragonFly better, going by IRC conversation)
BSDNow 133 is a recap of everything seen and done at the just-concluded AsiaBSDCon 2016. In addition, there’s a conversation with Brad Davis about packaging FreeBSD’s base system. (there’s been talks about this before.)
(I know AsiaBSDCon 2016 was streamed; was the video made available?)
If you are running bleeding-edge DragonFly, Sepherosa Ziehau has made some networking changes that both reduce CPU usage in high-traffic situations and change some underlying network structures. This means a full buildworld is needed on your next update.
If you’re using DragonFly 4.4.x or older, you are unaffected.
I’m actually a few days late pointing at this, as it came out a few days ago. Anyway, the most-recent-at-this-point Garbage podcast is out, talking about VAX going away, and ends with a good note about donations, and how just giving your pocket change helps.
If you’re somewhere around Michigan tomorrow around 7 PM, Michael W. Lucas is presenting at the SEMIBUG meeting, on FreeBSD filesystems. See the group site for location.
I had too many links for this as early as Tuesday.
Your unrelated video link of the week: Rotoscoped Horse. Taken from the old Muybridge photos. (via)
Has anyone been watching the AsiaBSDCon video? I have not been awake/unbusy at the right times.
If you find yourself using gpt and disklabel64 for a new disk, and aren’t quite sure what order to type everything in to create a disk slice, why not crib from Tim Darby’s notes? (note that the archive has added some line breaks to it.)
BSDNow 132 is up, titled “Scaling up with BSD“, with an interview of host Allan Jude about ScaleEngine, plus a bunch of news links. There isn’t the usual longer writing because they are currently at AsiaBSDCon, and I saw that there are streaming links for the events there. Look at the schedule, watch, and I hope there’s saved video too.
The ‘hammer show’ command can be used to dump the B-Tree structure of a Hammer volume, and CRC errors can be spotted. It’s rare that anyone would need it, but if you do, this dumped information will include file hierarchy information.
If that makes you a bit nervous to repost any of that information when talking about it in public, Tomohiro Kusumi has added an ‘obfuscate’ option to ‘hammer show’ that does just that – it hides path information from the debug output.
Sepherosa Ziehau has continued his quest of making large-scale data transmission on DragonFly effortless; his latest change has cut the kqueue contention rate by two-thirds when dealing with a connection rate of nearly 400,000 connections per second. Note that’s number of connections, without even tracking the bandwidth used by each.
John Marino rearranged how GCC5 handles CPUTYPE settings. If you are specifically setting the target CPU when compiling, his commit will give you an exact list of what to target.
Note that I am not saying another architecture – this is all x86_64. I also don’t recommend doing this unless you have a specific use for it – compiler overoptimizations often create more problems than they fix.
All over the map this week.
Your unrelated link of the week: teasmades, 50% off with the code ‘MOTHERSDAY2016’ until March 9th. Given the difference in US – UK voltage, I don’t know if this would be a good investment for me, but I’d sure like to have one.
I hope you have some time for reading this week.
Garbage 16 is out, with OpenBSD news and general tech talk. There’s apparently progress on Raspberry Pi 3 support.
(Podcasts tend to be timely, and time-dependent, so I’m not saving this for the weekend In Other BSDs)
Daniel Bilik has found there’s an issue with i915 acceleration, Baytrail CPUs, and some AUTODEEP low-power states. This will only affect you if you are using that specific hardware combo and setting certain low power modes. Interestingly, it affects other platforms, too, as it appears to be a symptom of how the video is addressed, not a DragonFly-specific bug.
BSDNow 131 is out, and has an interview of Jamie McParland, on I assume the topic of BSD in school environments, guessing by the title and guest’s email address. It has the normal summary of news items, including explanations of load average I think many people would find useful.
I almost missed this: There’s a NYCBUG meeting tonight, at 6:45 PM, at the Stone Creek Bar and Lounge in New York City. The presentation will be from Raul Cuza, titled “BSD init(8) and rc(8): Room for Improvement?“. I imagine there will be an opportunity to complain about systemd’s very existence, at this meeting.
UNIX tools are this week’s unintentional theme.
Your unrelated robot link of the week: Every new Boston Dynamics robot is creepier than the last.
Look at the ZFS discussions if you want to feel smug as a BSD user.
Normally I’m just linking to BSDNow, but there’s even more BSD-themed media coming up today: BSDNow 130 is out, titled “Store all the Things“, with an extended summary of the recent Storage Summit.
Garbage episode 15 is out, titled “Compressing with Broccoli“. It notes a lack of activity for Bitrig – I still see commits happening, though.
Bill Yuan has added ‘ipfwsync’ to ipfw3 in DragonFly. As you may expect from the name, it’s a way to sync ipfw3 configurations across multiple devices.
I see this bite people irregularly over the years: if your default shell on login can’t run, what do you do? I’ve seen it happen because of a missing /usr/lib, and it can happen with out-of-date library references, too. There’s several different ways to deal with it:
That last one may be useful if your dports setup gets mangled, somehow – though ‘pkg upgrade’ has always worked for me.
Francois Tigeot has again updated Intel i915 video support in DragonFly, bringing it even with what’s in Linux 4.2. This will be very useful for Broadwell and Skylake users, and even Broxton, apparently the newest Atom platform.
Welcome the newest DragonFly committer: Bill Yuan. His ipfw3 work has been going on for a while.

Your unrelated link of the week: The Voynich Manuscript and Codex Serahinianus, in PDF form. Ignore the “never-cracked ancient mystery” bit about the Voynich Manuscript, but it’s still interesting to look at.
Keep an eye out for BSD user group meetings in your area – just because I didn’t note it doesn’t mean it isn’t happening.
BSDTalk 262 is available, talking with Tex Andrews for 23 minutes about LightZone, “open source digital darkroom software”.
BSDNow 129 is available. Along with the normal news summary, it has an interview with John Marino, the fellow behind DragonFly’s dports system, and author of recently-noted-here synth, which has reached version 1.0.
DragonFly 4.4.2, a bugfix release to 4.4.1, is out. This was mostly prompted by the recent OpenSSL update, but other little fixes have made it in, too. It’s available for download and is probably available at your nearest mirror by now, if you want an image. The release page is updated, and there’s always the Git tag summary for 4.4.2 for the most exact details.
I have DragonFly shirts, helpfully printed up by Sepherosa Ziehau in China. I have a list of people that are interested in shirts, most of whom remembered to give a shirt size. I don’t have anyone’s email address or mailing address on that list.
If you are on that list, send me your mailing address.
The shirts are marked L/XL/XXL/XXXL, but they run smaller than U.S. versions of those sizes. I usually find a U.S. XL shirt baggy, but “XXXL” is the one that fit me, for instance. I’ll do my best to place the appropriate one. This is just an advance apology, since it’s too late to change anything if it turns out tight.
I’ll mail these out as I have the spare cash and time on hand. (I hope most of you live in the continental U.S.)
Rapid topic shifts this week.
Your unrelated tea link of the week: Cuppa Thugs.
Several book links this week.
Thing I should link more regularly: Garbage, a podcast that isn’t specifically about BSD but happens to cover it a lot. I linked to it when it was starting, but didn’t catch new episodes (fixed by finding the RSS feed). There’s been a bunch since then, so you have plenty of listening material now.
If you have a Broadwell system, the drm.i915.enable_execlists tunable added by Imre Vadász may keep your system stable. (thanks, zach on EFNet #dragonflybsd)
It would help with Burp, which is being ported to a number of BSDs.
BSDNow 128 has an interview of Nick Wolff, the usual roundup of news items, and I’m sure something that matches the title of the episode, but I haven’t listened to it yet.
Rimvydas Jasinskas has consolidated/restored/updated a large number of papers into share/doc on DragonFly. I’m not going to link to his large number of commits, but instead point you at the directory where they all went. There’s a number of design documents in there that date back to 4.4BSD and beyond (and some much newer), which may interest or educate you. Of special note: The Guide to the Dungeons of Doom, for rogue, or the KAME IPv6 implementation notes.
If you’re building from dports, and you want to include debugging information, you’ll want to put ‘WITH_DEBUG=yes’ in /etc/make.conf. Note that this affects anything you build at that point, including world, which you’d want to rebuild anyway.
These probably apply cross-BSD, but in this case, it’s DragonFly tips for printing with CUPS.
A bit nostalgic this week.
Your unrelated video link of the week: Aircraft Crash Tests Composite Data Film. (via)
If you have a Core2 processor in a DragonFly system, it may not work with accelerated video. If that happens to you with this (admittedly old) processor, switch to VESA for now.
Once again, I’m a bit late posting about BSDNow; blame my classes. BSDNow episode 127 is up, with Willem Toorop as the interview subject, talking about getdns, with a link to his vBSDCon presentation.
The slides from yesterday’s shell-fu presentation at NYCBUG have been posted.
NYCBUG is having a presentation tomorrow, February 3rd, 18:45, Stone Creek Bar & Lounge at 140 E 27th St. in New York City. The presenter will be Isaac Levy and the title is “shell-fu”. .ike is an energetic speaker and it’s worth your time if you are near enough.
BSDTalk 261 is up, and it’s a half-hour conversation with Kris Moore about jails, system management, and other I assume PC-BSD features.
