Lazy Reading for 2016/03/27


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.

 

 

In Other BSDs for 2016/03/26


By the time you read this, I will have already been at my second job for 5 hours.

garbage[19]: sched_yield


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: Stein, Mercer, garbage


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: Marking up the Ports tree


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.)

Another update for Radeon users


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 here, too


unzip has been added to DragonFly, making it present in every BSD but I think OpenBSD.

UEFI for you and I


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.

clang in DragonFly, soon


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.

In Other BSDs for 2016/03/19


This time, this was all last-minute.

 

garbage[18]: Pixel C, Raspberry Pi 3


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.

Multiple card slots accessible in DragonFly


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: The Tokyo Debrief


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?)

World rebuild needed for DragonFly 4.5


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.

garbage[17]: A moment of silence for VAX


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.

disklabel64 tips


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 and also AsiaBSDCon


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.

Hammer not show


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.

Improvements for kqueue and per-CPU caching


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.

New CPUTYPE variables


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]: You guys got it wrong, your algorithms suck


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)

i915, Baytrail, and C-states


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: BSD Behind the Chalkboard


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.

NYCBUG tonight: BSD init(8) and rc(8)


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.

BSDNow 130 and Garbage 15 podcasts


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.

High-availability sync for ipfw3


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.

Default shells and library changes


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.

DragonFly i915 support: another upgrade


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.

DragonFly 4.4.2 released


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.

Who still wants a shirt?


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.)

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.

Whole lotta reading


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.

Debugging tips


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.

Printing tips


These probably apply cross-BSD, but in this case, it’s DragonFly tips for printing with CUPS.

More on privatization


For those of you running DragonFly-current, the already-mentioned library privatization going on means that ports have to be rebuilt.  You will want to do it yourself, or wait a little bit before upgrading if you want to install binaries.

BSDNow 126: Illuminating the future on PC-BSD

Privatization means rebuilds


That’s a pretty cryptic headline, isn’t it?  John Marino has ‘privatized’ several libraries in DragonFly, so that they can’t get included involuntarily as part of a port build.  That may mean you will need to perform a full rebuild of your system if you are tracking DragonFly-current.

(This is the way to fix ‘system’ languages like Perl was in FreeBSD 4.x – keep them clearly separate from the port version.  It’s about a decade too late for that idea to work out, though.)

License corrections for DragonFly


This has no effect on the actual operation of DragonFly, but it makes me feel better that it’s done: Rimvydas Jasinskas has gone through DragonFly source and removed the unnecessary 3rd BSD license clause, which is no longer needed.

There’s two important security updates for SSH.  DragonFly release and development have been updated for it, and you can correct for it on your running system using the one-liner at Undeadly.
