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.
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.
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.)
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.
- Domain Name Scams Are Alive And Well, Thank You. I’ve been seeing that scam since… 2007? Less disruptive than wire transfer spearphishing, which appears more common, recently.

DiscoverBSD for 2016/03/14.
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)
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.
