I guess the accidental theme this week is Unix.
- The truth about Unix: The user interface is horrid. From 1981, which says something. (via)
- Terminal: Beyond Ctrl + A and Ctrl + E. Linked because I needed to know what the nondestructive version of Ctrl-U was. (Ctrl-A)
- Tools don’t solve the web’s problems, they ARE the problem. I’ve been considering a static generator for this site, for similar reasons. (via)
- How to name things: the hardest problem in programming. A dry topic talked about in a very human way. (via)
- Floppy Drive Organ.
- Cold Weather, Gogol And The Rise Of The Russian Samovar. I don’t need one, but I’ve always thought samovars are interesting.
- Unix Shells: Bash, Fish, Ksh, Tcsh, Zsh. (via)
- When Poll is Better than Interrupt. (PDF, via EFNet #dragonflybsd)
- A Repository with 44 Years of Unix Evolution (via)

Your unrelated link of the week: svblm. Found via a link to Infinideer and Forest Ambassador.
A calmer week, probably because of the U.S. holiday.
A recent commit from Matthew Dillon means users of Intel Haswell or later CPUs will see reduced power usage, if I’m reading this commit correctly.
This week’s BSDNow episode talks with Jed Reynolds about ZFS on Linux and FreeBSD, and includes other news bits including about DragonFly’s swap encryption, OpenBSD defaulting to having openntpd on by default, and plenty more.
Hammer will perform daily housekeeping tasks each night. If you’re up late enough, it may kick off while you are working. If you want to stop the process after it’s already started (since it’s disk-intensive), John Marino has added the ‘abort-cleanup‘ command.
If you want to use a scanner on DragonFly, install SANE. That is apparently all you need to do.
Experimental automatic crypting of swap is now available in DragonFly-master. Recently added, though it may have been possible another way.
Your unrelated comic link of the week: Finished page at the Toronto Comic Jam. I missed TCAF this year, dangit. It is awesome. (via)
This includes all the BSD material I didn’t have time to get posted last week. I hope you have some time for reading today; there is a lot here.
- Royal activity affecting your open source files.
- Windows guest support (or at least the start of it) in bhyve.
- Bad memory blacklisting in FreeBSD. I’d be worried about keeping partially bad RAM in place, but this is probably being used on a larger scale.
- 25 year old col bug, fixed.
- The start of NUMA support in FreeBSD.
- Alpine POC and Routerboard support in FreeBSD.
- FreeBSD now supports more than 8 audio channels.
- NetBSD is starting to gain EdgeRouter support.
- NetBSD gains in-kernel splash screen support.
- Openresolv 3.7 is in both FreeBSD and NetBSD.
- EU study recommends OpenBSD. (Thanks, PCTF)
- Now, sshd in OpenBSD defaults to ‘PermitRootLogin=no‘ (like in DragonFly!)
- Device Developer’s Conference, happening in the UK over the next month or so. (via openbsd-misc)
- OpenBSD has released, shipped, and there’s some discs with errors being replaced, though there’s a workaround.
- From 0 to an OpenBSD install, with no hands and a custom disk layout. (via)
- Livingston County, Michigan has a BSD user group starting up.
- PC-BSD 10.2.1-RC1 comments.
- BSDCon Brazil 2015 has a call for papers out.
- New to BSD, Questions about Firewall configuration.
- DiscoverBSD for 2015/05/11.
- A week of pkgsrc #10.
- PC-BSD 11.0-CURRENTMAY2015 images now available
- Yes, You Can Virtualize FreeNAS
- pfSense is now available as a “VMware Ready Virtual Firewall Appliance“.
- Michael W. Lucas’s Tarsnap talk is online.
- As is the cover to his upcoming FreeBSD Mastery: ZFS book.
- BSDTalk 253 has 30 minutes of conversation with George Neville-Neil about “The Design and Implementation of the FreeBSD Operating System”, 2nd edition.
leaf.dragonflybsd.org, where the DragonFly website is hosted, is temporarily down while a disk is replaced. Images and binary packages are still available.
This week’s BSDNow episode talks with Mike Larkin about memory protection in OpenBSD, along with the normal news summary.
This may not be a huge surprise, but the Minnowboard MAX can run DragonFly just fine, modulo some dmesg complaints.
Sepherosa Ziehau has introduced a new sysctl:
Set this to zero and you won’t get endless ARP events from networks you aren’t on. For example, I’m hooked up to a cable modem. I only get a public routable IP address, but the network used for the cable modem network itself bleeds ARP packets out where my DragonFly machine can see it. Since it’s on a different network segment than the address I receive through DHCP, it always fails and the system logs it. For example:
May 11 05:20:52 www kernel: arplookup 100.68.112.145 failed: host is not on local network
I can’t do much about it since that layer 2 leakiness is going to happen, but I can shut it up with this sysctl – and thank goodness, cause I’ve been seeing these messages since first using a DOCSIS modem in… 2001 or so?
Accidentally very roguelike this week.
Francois Tigeot has committed his Broadwell work, which has a longer-than-I-realized list of benefits. Does anyone have a 4k screen to try?
BSDNow 088 has an interview of Ed Schouten about FreeBSD, and all the normal roundups. Also “DragonFlyBSD has officially won the race to get an Intel Broadwell graphics driver”.
Maybe I need to start doing In Other BSDs posts on Wednesdays, cause BSDNow often has the links I’m already saving for the weekend.
John Vernaleo is giving a talk for NYCBug about Bitrig, tonight at 6:45 in New York City. See the announcement for details on location and etc.
Jesse Wattenbarger wrote in with his success story of switching to DragonFly, both for server and desktop. Of note is his noticeable speedup with swapcache.
If you’re running DragonFly-master and you have an Intel video chipset, Francois Tigeot has an update for you. It brings accelerated Intel video up to match the Linux 3.14 version, adds Broadwell chipset support, and should generally improve performance. He lists how to test right in the message.
I started sparse because this was a busy week, but I’ve still got a pretty good amount of reading for you.
I’ve already mentioned the Hammer2/OpenBSD Summer of Code project (one of several), but here’s more:
(No mailing list links this week; I’m way behind in my reading because of work. Sorry!)
DragonFly committer Joris Giovannangeli has a Google Summer of Code project. He’s bringing Hammer2 to OpenBSD, in single-node form. It’s a very difficult project, but Joris is a very talented worker.
BSDNow 087 has an interview with Christos Zoulas, about NetBSD and blacklistd, along with the usual collection of news stories that I’m trying not to peek at because I’m behind on my usual reading and I want to get my own collection together for Saturday’s In Other BSDs.
Tomohiro Kusumi has been quietly making a lot of commits to Hammer. I haven’t been linking them because they don’t necessarily equate to new features, but here’s an recent exception: the -A argument will make your Hammer command run on every PFS. It only affects reblocking/rebalancing – for now.
We’re already 2/3 of the way to Christmas!
Your unrelated tea links of the week: Do you even steep? The actual title is different, but I like that part of the link more. (Thanks, Jeff Ramnani) Also: Tea With Strangers. It’s exactly what it sounds like. Unfortunately, it’s not in my city. (via)
It’s been a relatively calm week, for once.
You can now export Hammer slave volumes as NFS mounts – but since slave volumes are updated from master, you’re mounting a snapshot of that point in time. That may actually be an advantage.
DragonFly builds two compilers by default. If you weren’t interesting in building both, there were switches to build only the default, like NO_GCC47. This changed with every compiler update.
With the switch to GCC 5, the new switch is “NO_ALTCOMPILER”. That will last through compiler changes. I’m mentioning this now because sooner or later, you’ll want to gain back some time on a buildworld.
BSDNow 086, just out, has the usual roundup of news, plus an interview with Antoine Jacoutot about OpenBSD and BSD in business environments.
DragonFly now has GCC 5.1 release. If you are running DragonFly master (i.e. 4.1), you’ll probably want to both rebuild world and kernel, and update your packages so they all match. There’s already packages built with GCC 5.1, so binary package upgrades can happen quickly. There’s GCC 4.7 packages still available if you aren’t making the jump yet.
If you’re on DragonFly 4.0.x – nothing’s changed.
I’m late posting about these, but they go together: Sepherosa Ziehau has added the ability to read CPU temperature through various sysctls, and the same for DIMM temperature readings.
Spillover from last week, even.
Your unrelated video links of the week: 80s nostalgia is happening now that there’s a generation young enough to not have experienced it. You can have the 1980s as a parody, or as the real, unmitigated awfulness.
I couldn’t help the commentary on some of these links.
Matthew Dillon bought a system with a Broadwell series CPU, installed DragonFly, and wrote up his experience. Read it if you plan on purchasing this hardware any time soon.
Here’s some comments from Matthew Dillon on page coloring in DragonFly; a topic that comes up every year for some reason.
The release candidate for GCC5 (5.1.0) is out, and it’s in DragonFly too. It’s not yet switched over to run as the default – that’ll require the release.
Episode 085 of BSDNow has a conversation with Pascal Stumpf about PIE in OpenBSD, along with the usual mix of news. In the mix is a link to the 1.5.0 release notes for pkg, which affects a number of BSDs, DragonFly included.
The default compiler in DragonFly is going to change over from GCC 4.7 to GCC 5.x very soon, to match the GCC 5.1 release. This means that packages built for DragonFly-master won’t be compatible with the old ones. You will need to reinstall packages when you next ‘pkg install’. John Marino has an extensive writeup detailing what’s needed, and the actual change is some days off.
If you are using DragonFly 4.0.x (the release), this doesn’t affect you at all.
Francois Tigeot has a new update to the drm/i915 driver for testing. It matches, feature-wise, what’s in Linux 3.12. Try it if you’ve got the hardware. (and dragonfly-master)
The insulation on the external lines leading here are apparently delicious, if you’re a squirrel.
I have had trouble with my daily/weekly periodic reports never making it to my GMail account. Sascha Wildner pointed out to me that periodic.conf has its own answer already:
… and newsyslog is already set to take care of them. There’s more in the periodic.conf man page.
Without meaning to, I’ve broken into full-on computer nostalgia this week. Don’t know how it happened, but at least the links are interesting.
Your unrelated tea link of the week: The man who drank too much iced tea. He wasn’t drinking that much, which makes me a bit worried about my own hot tea consumption. (via)
Your unrelated psychedelic rock video of the week: Lightning Bolt’s The Metal East. If you find the art interesting, start looking for Fort Thunder comics. (via)
At the last minute, as usual.
Lastly: nvi2, a multibyte folk of nvi, seen in multiple places. This may be good for every BSD to adopt. (every other BSD, I mean.)
There’s been some linking to the updated HAMMER2 design document. The Reddit link doesn’t have anything specific, but the Hacker News one has some details (including a credit code!) for installing DragonFly on a Vultr VPS.
The most recent (well, this is the mostest recent) update of ACPICA for DragonFly, by Sascha Wildner, is different from the usual import: it happens to include actual upstream support for DragonFly
This week’s BSDNow talks with Baptiste Daroussin about developing and using pkg, for ports and for packaging the base FreeBSD system. (Baptiste has been seen on #dragonflybsd, since pkg is on DragonFly, so I’m sure there’s some relevant bits there, too.) There’s also the usual news summary.
I haven’t been drawing enough attention to it, but there’s been a bunch of HAMMER filesystem activity lately: First, Tomohiro Kusumi has been working on HAMMER – these posts are a small subset of his commits. Second, Matthew Dillon has been working full steam ahead on HAMMER2. The HAMMER2 design document has been updated (read this!), and he’s already accomplished master->slave disk syncing.
It’s not ready for production, of course, which you may already realize, so don’t install it unless you want to work on the code.
Happy Easter! It means chocolate for me.

Your unrelated comics link of the week: Jason Shiga’s comics. It’s an article about the comics, not the comics themselves, so go to his site next. (via)
Also unrelated: tea is one of the topics I link here, and alert reader Jeff Ramnani pointed out Strand Tea as a good source. I also saw Deep Mills referenced in the UK. Anyone else have a favorite online vendor?
If you’re part of a BSD user group, please let me know your schedule. I’m able to catch NYCBUG announcements cause I’m on their announce@ mailing list – but I could use more.
Do you use info pages? Yeah, me neither. John Marino’s removed or converted the various info pages already in DragonFly, and removed texinfo since it’s no longer required. (I’ve linked to a few examples, but there were a number more commits than this.)
This week’s BSDNow has the usual roundup of news, including some… suspicious items, plus an interview of Kamila Soucková about conferences and Google Summer of Code. They note this Hammer2 proposal.
Today’s the annual Bad Tech Joke, also known as April Fools Day. I don’t do those here, cause I think of them like this. This is your public service announcement to ignore most of what you read for the next 24 hours or so.
The default .cshrc in DragonFly has had some changes, which shouldn’t be anything but handy… assuming you are using tcsh. Also: the loader menu defaults to a blue Fred, now.
In the process of committing binutils 2.25 to DragonFly, John Marino also broke its build into parallel parts and removed the build of the gold linker. Buildworlds should be noticeably faster now, though I don’t have a before/after.
John Marino’s written an extensive page about wireless and DragonFly, on dragonflybsd.org.

Unrelated link of the week: Tea. Contains strong language.
It’s been a quiet week in BSD-land, at least in terms of me finding links.
If you’re looking to change your DragonFly system’s keymapping to support a non-US character set, use this users@ post from Adolf Augustin as a cheat sheet to make all the right changes.
Matthew Dillon answered some mailing list questions on how clustering and data copies will work in HAMMER2 – no due date, of course, because this is very complex. If you’re really into it, there’s always watching the recent commits.
BSDNow 082 is up, talking with Bernard Spil about LibreSSL adoption in FreeBSD ports. There’s lots of other material listed – see the BSDTalk page for a summary of all the topics covered.
Matthew Dillon has rewritten the Locking and Synchronization documentation for DragonFly. Keep this in mind the next time you say “Which lock should I use for this new software/ported software?” There’s also locking(9).
BSDTalk 252 has 18 minutes of conversation with Brian Callahan, who runs devio.us, an OpenBSD-based shell provider.
The other day, I updated some packages using pkg. The default version of PHP went from 5.4 to 5.6. I ended up doing what /usr/dports/UPGRADING says and making a list of all PHP packages on my system, before removing PHP and its dependencies. I then reinstalled the packages that used PHP, bringing the needed packages back in at the right version. pkg 1.4 didn’t handle the transition cleanly, unfortunately. I also had to specify mod_php56 because pkg was trying to get the 5.4 version despite it not being default.
None of these are insurmountable problems, but it never hurts to be forewarned. pkg 1.5 is on the horizon and may have an easier time with sorting these types of dependency/version changes. This may apply to FreeBSD in addition to DragonFly.
I’ve tagged version 4.0.5 of DragonFly, and it’s available at your nearest mirror. This revision is mostly to incorporate the newest OpenSSL security bump.
As you read this, I am probably watching a storage processor reboot.
I’d love to see fewer developers demanding superficial perks, and more of them asking to have more time to contribute to the open source products we use, mentor young developers, and learning more about the space they occupy. All of those result in us growing as developers in more than just our coding skills.
Your unrelated link of the week: National Corndog Day. Has audio. (via)
Not done in a last-minute rush before the weekend, yay! Done early cause I have to work over the weekend, boo!
OpenSSL has yet another security update, and Sascha Wildner has added it to DragonFly. It probably justifies a 4.0.5 release, so I’ll be working on that.
As a side effect of the new ipfw3 import, the sshlockout script included with DragonFly now has -pf and -ipfw options.
Some recent users threads pointed at SSD wear stats, along with what Matthew Dillon has seen on dragonflybsd.org machines, and good filesystem books.
Bill Yuan’s work on a new ipfw has been committed, and for clarity, called “ipfw3“.
Happy (almost) St. Patrick’s Day! An excuse in the U.S. to wear green things and drink beer.
I goofed up and didn’t complete last weeks’ In Other BSDs before it published, so you get some extra this week.
Next time you’re building or installing world on your DragonFly system (running master), your computer will do a better job letting you know the status.
Matthew Dillon pulled in a new USB update from FreeBSD to DragonFly. What does it change? I’m not completely sure, but he did it to get apcupsd working, so that may be a hint.
If you have a HDMI-connected monitor, but no sound, this trick about increasing available memory may help.
The newest BSDNow video goes into PC-BSD and booting, and interviews Justin Gibbs about the FreeBSD Foundation.
Hey, look what I have! There’s a pfSense pair of classes available to take. I went through them and found them worthwhile. pfSense is easy enough to use that a dedicated person can puzzle through most of the settings, eventually, but I don’t have “eventually”, and I want to encourage BSD products in my workplace… so here we are.
DragonFly 4.0 has had a minor point release, to 4.0.4. There was a bug in the initial install where the rescue image installed on disk would be incorrect. This was fixed after the first time a build/installworld was done, but might as well have it start out right. There’s some other small fixes, and the release commit will show you the summary. Download from your nearest mirror or update normally.
