Matthew Dillon has written up another update on his progress with HAMMER2. (I need to be consistent in how I write that.) He has disks being exported and mounted on other systems, and adds an explanation of some of the issues around creating reliable multi-master setups. Before you get too excited, no, multi-master isn’t working yet, and this is not production ready.
There’s more benchmarks for DragonFly vs. other systems on Phoronix. It has the same problem as previous benchmarks; some of the benchmarks may have no connection to reality (what does the “Himeno Poisson Pressure Solver” actually test?), and almost every system has a different version of the gcc compiler. So it’s meaningless in terms of comparative or absolute performance. On the other hand, DragonFly doesn’t do badly.
You can also look at the comments to see someone absolutely freak out over the very existence of things that aren’t Linux. I’m not sure if it’s actually trolling, since the comments are so exactly wrong.
This is a mini-theme Lazy Reading, where I find small groups of related things.
- Exploratory data analysis with Unix tools. The command line is a far better place to mangle data than you’d expect. Well, maybe not your expectations, given that you’re reading this site.
- “The UNIX System: Making Computers More Productive” Brian Kernighan, Dennis Ritchie, and Ken Thompson in 1982. I found that after reading “Open Source Guilt & Passion“, which is a quite accurate description of working on open source, or perhaps any volunteer work. (via).
- While talking about people of that generation: Here’s Rob Pike’s Go slideshow (linked previously) in a single-page text format. (via)
- And we can get even older with this article about the Computer History Museum in California. There’s a lot of pictures of hardware ‘firsts’, like a light tracking, self driving robot from the 1940s, or the first mass-produced transistor radio. Look for the hardware that shows where ‘core dumps’ came from. (via)
- Found on the previous link: Rebuilding the IBM 1401. I like looking at the old “fill-up-a-room” computers, since they look like supercomputers. I wouldn’t want to actually possess a mainframe; they aren’t powerful, eat electricity, and so on. Well… I can think of one that would be OK.
- The Enduring Object. I find it oddly reassuring when hardware doesn’t change because it works so well. It’s sort of like an inherited tool from an older relative; something worn from use but distinctly better than buying new.
- The 2012 Good Gift Games Guide. There’s some really neat board games in there.
- Along the same lines, Designing Board Games with Perl.
- The First Few Milliseconds of an HTTPS Connection. An in-depth dive with Wireshark and an explanation of RSA. My cup of nerditry runneth over! (via)
- It wouldn’t be a Lazy Reading post without some Git thingie. This time, it’s “Git: Twelve Curated Tips And Workflows From The Trenches“. (via)
- The DuckDuckGo command line. (via)
- Exploring Emacs. Posted mostly in the interests of equal time to vi-ish stuff. (via)
- “What a Wonder is a Terrible Monitor“. A Jason Scott article about emulating old monitors in software, with videos showing the difference. I’ve seen the hardware difference he’s talking about. I’m distressed just knowing my children probably don’t recognize analog static. (via)
Your unrelated link of the week: The Museum of Ridiculously Interesting Things. Also known as ‘old weird crap’, but that’s OK – still interesting.
I knew about files like /etc/services, for common IP port usages, and /usr/share/zoneinfo, for time zones, but I didn’t know that DragonFly (along with other systems) keeps a list of agreed names for various human languages defined by ISO639 in /share/misc/iso639, and it’s maintained at least in part by the Library of Congress. At least I didn’t know until Sascha Wildner updated it.
Michael W. Lucas has a coupon code for his new edition of Absolute OpenBSD, so jump on it now. I haven’t read his first edition, but his other books are certainly good.
It’s the end of the year, so it’s time for the FreeBSD Foundation’s end of year campaign.
If you’ve ever wondered how building all of pkgsrc would go with GCC 4.7.2, which is in DragonFly but not the default compiler, John Marino can show you just that. He has a list of the results from a bulk build of all packages on DragonFly with GCC 4.7.2.
It’s been a quiet week, but that’s OK. I have sick kids, sick coworkers, and a certification test this Monday…
- Playing at the World is apparently a good book. The author has a blog where he dives into old RPG minutiae. You will either find that not very interesting or super interesting. No halfway point.
- Teleglitch, a roguelike top-down shooter with pixel graphics. I was happy at the word “roguelike”, of course. (via _hasso_ on EFNet #dragonflybsd)
- A review of Version Control with Git, 2nd Edition.
- “I’m writing my own OS“. I think Dominic Giampolo said once that everyone in computer science goes through a phase where making your own operating system can’t be too hard and why not try it etc etc. (via)
- This picture makes me happy.
- An entire book of studies based around a single line of C64 BASIC code. It’s available as a free download.
- Teach Your Children Groff. It’s sort of the opposite of the do-without-needing-to-understand practice that most people assume Steve Jobs wanted. (via)
- Your Objects, The Unix Way. (via)
- Getting your computer work done in 1973. Given the hardware, I don’t think this is Unix, but it’s still neat to see it work. Punch cards! (via)
- Here’s how arcade cabinets were first planned out. I like seeing the old-school marker rendering.
- This notebook seems like a bad idea. (via)
- This secure bootloader, on the other hand, could be useful. (via)
- A hypnotic data visualization. (via aggelos on EFNet #dragonflybsd)
- A Star Wars roguelike on GitHub. (via)
Your unrelated link of the week: GET LAMP. I thought I had linked to it before, but I’m probably thinking of It Is Pitch Dark. It’s a documentary by Jason Scott of textfiles fame about text adventures.
Michael W. Lucas announced his next book will be about DNSSec, which is good. It’s also self-published, which I like to see. I don’t know if it necessarily makes him more money, but I like to see more exploration of this new way of publishing.
If you look at his announcement, there’s a link to something else: vendor-free SSL certificates. These are possible? That’s one of those things I didn’t even realize I wanted; having to deal with a certification authority is annoying.
