Lazy Reading for 2012/04/22

Enjoy!

I like the sentiments here about Instagram. (via) I can see why it was popular, but not how it represented anything but a cosmetic tool, dependent on other services.
Waxy.org turns 10. I relink (reblog? I don’t know) material from the links page on waxy.org, because Andy Baio has a keen eye. That article has links to various high points over the last 10 years, so it’s worth setting aside some of your time and looking at previous features. Come to think of it, he started that only a year before I started this Digest.
Supercomputers installed at the Lawrence Livermore National Laboratory. All the way back to UNIVAC. (via swildner on EFNet #dragonflybsd) This picture is one of the more realistic I’ve ever seen about rack installation.
RFC6540: IPv6 Support Required for All IP-Capable Nodes. (via) YES.
The Story of BSD and Open-Source Linux, unfortunately incorrect, starting with the headline.
40 years on: Why Unix standards still matter. A brief note about the Single Unix Specification. There’s some implication that Unix was involved in the moon landings; was that the case? I didn’t think so, since at least a chunk of the moon landings predate Unix existing. (i.e. before the Epoch.)
A photo followup on the one PHP article from last week. (via aggelos on EFNet #dragonflybsd)
From the same site as the PHP article, tmux is sweet as heck. It’s nice to see the positive points of tmux defined outside of licensing. Also, it serves as a good tmux configuration checklist.

Your unrelated link of the week: One Thing Well. The BSD tag might be the most useful.

OpenJDK7 building

Based on a recent post from Chris Turner to the tech-pkg@netbsd.org mailing list, here’s a bug report that should get you to a working lang/OpenJDK7 pkgsrc package.

Lazy Reading for 2012/04/08

The links are all over the map this week, which is fine. Enjoy!

This makes me laugh every time. (via)
Etsy has an astonishingly good internal development practice. And open source code? (via)
For contrast, Facebook’s release engineering process. (via I lost it, sorry) Not as interesting but I can’t tell why.
Mosh, a program designed for the persistence of screen but differently. (via) Dunno if it builds on DragonFly, but it looks neat.
I’m getting more paranoid as I get older. Things like this Javascript ad injection on hotel wi-fi may be a reason. (via)
“I just ran emacs. LOL!“
0x10c, a sci-fi game set in the future with spaceships running a 16-bit CPU. That you can program.
I wish I could write here with the same mix of loathing and excitement found in this comics review. Warning: mildly… gonzo?
The journey from user to contributor, a NYCBUG talk in mp3 form. (via)
I’ve mentioned RetroBSD before, but here’s an example of it being installed on a Duinomite board. 2.11 BSD on a super-cheap, super-small Arduino-style board! (via) I don’t know what I’d do with it, but I want one. It even has keyboard and VGA ports.
At some point, this CPU database will be handy. (via)
A new, slow form of brute force ssh attack. (via) What I find interesting here is not so much the new attack itself, but Peter Hansteen’s careful gathering and analysis of data around it.

Your unrelated link of the week: memepool. It’s seen some activity lately. It was a blog before there were blogs, and I was part of it.

Fixing X video performance

I’ve seen a few people complain about poor video performance in DragonFly, in Xorg. If you see a bunch of “contigmalloc_map: failed …” errors in your dmesg, your video card needs more contiguous memory allocated. Set vm.dma_reserved to 32M in /boot/loader.conf and you should be set. If that doesn’t work, try 64M.

Apache in jail: a tip

Konrad Neuwirth is running Apache inside a jail, and getting some weird errors. Obviously I don’t know the fix, but Chris Turner knows what the settings need to be.

How to idle on #dragonfly

A tip for anyone who hasn’t tried this yet: run irssi in screen, and connect to #dragonflybsd on EFNet. You can then resume your screen session at any time after disconnecting and see the backlog, catch people addressing you directly, etc.

Before anyone says it: yes, I know, tmux works too.

Lazy Reading for 2012/03/18

I’m making sure I post this Lazy Reading on the right day. A nice full week’s worth of stuff.

Bandwidth used when loading different web pages. (via) The largest one is also the most surprising.
Do you have an IBM x3550? Turn ACPI off.
The recent TCL presentation at NYCBUG is available in audio form.
Did you want to know a lot of detail on how to do journaled soft updates in UFS? You want detail, you got it. (via, via) (Is that a repeat link? I don’t think so…)
This is totally useful if you’re using ssh from a Windows machine.
SSH is used as a noun and a verb, I just realized. No link, it’s just me noticing verbification.
BSDCan 2012 registration is open. (via Michael Lucas’s Twitter feed) Conventions are awesome. You should go.
Michael Lucas talks about book promotion with his recent book. There’s a graph, so it’s automatically great.
Speaking of books, Modern Perl: The Book is free to download in PDF form.
A story about _why. (via) I’m not so interested in his identity, but in what he did to get people to program.
My git habits. (Not mine; that’s just the title.) Speaking of learning, I’ve always thought the next steps past learning the basics of anything is to then see how experienced people approach it, idiomatically.
Why Juniper Gives Back to the FreeBSD Community. I link to this because I like what they are doing, and also because in a perfect world I would rather have a BSD-ish interface on my networking equipment than fiddle with IOS. Oh well.
Bunnie Huang always builds neat stuff. This time it’s a Geiger counter. (via)

Your unrelated link of the week: Neo Scavenger. (via) It’s a game, in Flash, and in beta. If you like postapocalyptic survival, it may be for you.

Running something once

Have you ever tried to run a service and realized you forgot to make an entry in rc.conf to enable it? It’s mildly annoying. There’s now a “one’ keyword (via NetBSD) that lets you enable a service, once. It still apparently performs sanity checks, unlike the otherwise-similar ‘force’ keyword.

Remote Web Browsing via OpenSSH and PuTTY

That’s exactly what Michael Lucas talks about in this recent post; using ssh to browse from a different machine, but using a local web browser. He uses it to get around a network problem, but I imagine there’s a number of other applications. This is one of the valuable tips from his recent book.

Hello new DragonFly 3.0 users! This is my not-about-DragonFly weekend link roundup. I’ll be back to regular DragonFly-ish stuff tomorrow.

Vim anti-patterns, Gnuplotting, and Computing History At Bell Labs. I’m combining what would normally be 3 separate points because I stole them all from Christian Neukirchen’s blog. I wish I had found them first.
I mentioned Dungeons & Dragons last week, which led Michael Lucas to point out Dungeon Crawl Classics in the comments. Along that same theme, here’s some 70’s role playing game illustrations. (via) There’s a parallel between computing in the late 1970s and fantasy; expert programmers were called wizards, understanding computers was an esoteric art… I could develop the heck out of that thesis, but let’s just look at the pictures and feel nostalgic instead.
And then everything got a lot more weird-looking, 20 years later! (via)
Hey, that time zone lawsuit mentioned here before was dismissed. That’s good news. (via lots of places)
Hyperpolyglot: Scripting. Look for your favorite scripting language and compare it side-by-side with others. (via ferz on EFNet #dragonflybsd)
The text of the DragonFly 3.0 announcement gets copied around to a lot of sites, far more than I’m linking here. However, I found this one entertaining because it kind of makes it sound like DragonFly is just what I happened to come with.
Custom 3D printing is becoming accessible enough that I’m trying to think of things I could get printed that way, even though I don’t need it. (via I lost it, sorry)

Your unrelated link of the week: Quigley’s Cabinet. Read her books if you have a fascination with old dead things.

WHMCS installation notes

Michael Lucas installed WHMCS, a commerical hosting management tool, on FreeBSD. He tells a story of doing so, and in the process happened to list all the PHP modules needed for it to run. I’m linking it because that list is going to come in useful for someone, someday.

BSD, BIND, and DNSSEC

If you were thinking about implementing DNSSEC, Michael Lucas did it himself and wrote down his notes. You can read them and either follow along to implement it yourself, or just spectate. The one disadvantage is that it uses BIND 9.9, and I only see 9.8 and 10 in pkgsrc.

Odd DVD drive issue

Edward Berger found that using a LG/Hitachi DVD drive kept him from successfully booting a DragonFly install CD. Using other manufacturers worked out fine. What causes the problem? I don’t know, but it’s worth mentioning it out loud in case someone else gets bit by it.

Updating Samba to 3.6

I’m posting this because it will save someone (possibly me) an hour of aggravation someday. If you are updating Samba from version 3.0 or 3.3 to a later version, it’ll take your existing config but possibly silently break on user authentication.

Getting rid of lpr

If you install CUPS, or know that you will never print using lpr(1), you can make sure thatyour DragonFly system never builds lpr again by putting NO_LPR=true in /etc/make.conf.

Setting up a DragonFly wireless access point

What if you have a DragonFly system that you want to use for an wireless access point? Andrey N. Oktyabrski did, and he helpfully listed his solution.

How to get DNSSEC going

I just mentioned DNSSEC in last week’s Lazy Reading, and here’s a “How to get DNSSEC with BIND 9.8.1 working” article from Michael Lucas. It’s pretty simple… Conveniently, BIND 9.8.1 is available in pkgsrc as net/bind98.

How much RAM is too little?

If you’re running DragonFly on a very low-end system, you may be wondering about memory requirements for Hammer. Hammer is much less RAM-hungry than ZFS, so it looks like you can get away with 128M, as long as you don’t mind the occasional error message. You can manually tweak settings for it if you like. 256M is plenty.

It still strikes me as odd to consider systems with less than 1G of RAM as “low-memory”. What rich times we live in!

Keeping binutils out of the build

There is now a NO_BINUTILS221 option, added by Sascha Wildner, that will keep your system from building binutils 2.21 during a buildworld. The system will still build binutils 2.22, so there will still be a functioning ld on the system. Use this along with NO_GCC41 (so only gcc 4.4 gets built) to speed up your buildworlds, if you like.

Loader changes for IPMI

If you’re looking to use IPMI and remotely watch the console of another system, Matthew Dillon has made some changes to help with that.
