8-way benchmarks for DragonFly and Linux

Phoronix has another set of benchmarks that include DragonFly and PC-BSD, along with several Linux distributions.  It’s interesting to see, though don’t take them as performance measurements.  7-Zip as a benchmark doesn’t describe much other than the program itself, and the Himeno benchmark results are because of the compiler in use rather than any underlying performance aspect of the operating system – for instance.  The DragonFly benchmarks disappear after page 3.

Book review: Absolute OpenBSD, 2nd Edition

Michael W. Lucas wrote a new edition to his Absolute OpenBSD book, and that second edition was published relatively recently.  It’s a hefty book, nearly 500 pages in length, and I’ve needed to write a review for some time now.  Not-necessarily-relevant-disclaimer: I contributed the IPv6 haiku/joke at the start of Chapter 12.  

If you’re interested in OpenBSD, it’s an obvious purchase.  It goes into detail for all aspects of OpenBSD, starting with a very detailed conversation about installation, then disk setup, and so on. This is not going to surprise anyone, of course.  Past the initial overview, the book starts with a chapter that talks about nothing else but locating other resources to help learn OpenBSD. It seems a little counter-intuitive to start a book with advice on how to look somewhere else, but it makes sense in light of the topic.

What if you aren’t using OpenBSD, at least not right now?  Something I didn’t realize until I had chewed my way through most of the book was that there’s several smaller books hidden inside.  The book goes very far into individual utilities.  So far, in fact, that it ends up creating mini-guides about the topics within the chapters.  (or entire chapters, in the case of pf.)

There’s in fact 2 chapters for pf, initial and advanced.  TCP/IP gets close to 30 pages just to itself, and topics like snmpd or chroot get an introductory section that assumes nothing about your prior knowledge.  These are technologies you’re using already, no matter which BSD flavor you’re dealing with.

It works as a reference.  I’m going to show the aforementioned chapter 11, on TCP/IP, to my coworker who makes a confused face every time I say “link-layer protocol.”  I don’t know if he’ll make it from one end to the other, but it’s a lot better than waving a hand in the air and mumbling “You should look that up on the Internet sometime.”  There’s enough detail that some of the smaller sections could probably be broken out into individual books, and I daresay that’s what is happening with Lucas’s Mastery series.

It’s comprehensive, it’s readable, and you’ll find something useful in it no matter your experience level.  The book is available in printed and eBook form, from the usual online stores linked at Michael W. Lucas’s site, or directly from the publisher.  It’s also available through the OpenBSD Project, which then gets a cut towards development.

 

Lazy Reading for 2013/04/21

I think spring has arrived; everything’s turning green, and a young man’s thoughts turn to computer hardware upgrades.  Time to move to 64-bit!  Anyway, lots of links this week.  These are getting more and more content-filled over time, but I don’t think anyone minds…

  • For the Bitcoin enthusasts: ‘…when my wife refuses to bring him cake on our sofa, he calls it a “denial-of-service attack”’ (via)
  • Make It So, coverage of computer interfaces from movies.  I always thought that was what Enlightenment was trying to achieve: the Interface From The Future.  (via several places)
  • Same computer interface topic, but from anime movies.  It would be nice if this became something people actively worked on, instead of Bitcoin selling and Facebook monetizing.  (via)
  • Flat icons/monochromatic icons seem to be another microtrend.  This is probably because few people do small dimensional icons well.  My favorite was always the BeOS set.
  • On benchmarks.  It says what you should already know, but I like the Phoronix/MD5 benchmarking joke.  (via EFNet #dragonflybsd)
  • This article titled “The Meme Hustler” draws a finer line than I’ve seen before between “open source” and “free software”.    The author, Evgeny Morozov, seems to also have a hate-on for Tim O’Reilly.  See some reviews of a recent Morozov book for a counterpoint, of sorts.
  • Spacewar championship, 1972, in Rolling Stone.  Exactly two years before I was born!   At this point, finding things older than me makes me a bit happy.  There’s a picture of a Dynabook in there, photographed by Annie Liebowitz.  It’s entertaining to read this 40-year-old story and see how well it predicts the future.  I’m also sort of amazed it exists, in Rolling Stone.  More Spacewar links here.
  • Meet the Web’s Operating System: HTTP.  “Because HTTP is ultimately the one social contract on the web that, amidst a million other debates over standards, rules, policies, and behavior, we have collectively agreed to trust.”  (via)
  • Ancient computers in use today.  I’ve linked to a story about that IBM 402 before,  but the following pages about VAX and Apple ][e systems are new.  Well, new to read, certainly not new hardware.  (via)
  • Yahoo Chat!  A Eulogy.  The spray of forbidden words is an entertaining acknowledgement message.  (via)
  • The $12 Gongkai Phone.  Bunnie Huang breakdowns are always fun, and he’s describing a strange sort of open source that isn’t through license.  (via)
  • The FreeBSD Foundation is looking to hit a million dollars donated this year, which seems quite possible given last year’s performance.  Donate if you can; their activities help the whole BSD community.
  • A Complete History of Breakout.  It’s not actually complete, but that’s OK.  It includes Steve Jobs being a jerk and Steve Wozniak being very clever, which is their traditional roles.  (via)
  • Ack 2.0 is out.  It’s a very useful utility; I’d like to see more standalone utilities created this way.
  • Space Claw, Flickr via BBS.  You’ll need telnet.   (via)

Your unrelated link of the week: Shady Characters, a typography/history blog I’ve linked to before, has a book out.  If you liked those links, you know what to do next.

entr(1); Run arbitrary commands when files change.

Eric Radman sent along a plug for a utility he is working on called entr(1).  The desciption is “Run arbitrary commands when files change.”  The site for it has several nifty examples – run make when *.c files change, or convert Markdown files to HTML as soon as they are modified.  The really nice thing about it is that it’s perfectly BSD-friendly, and uses kqueue, but will also work on Linux.  This beats the “This runs on the one flavor of Linux I use, in one particular shell!” approach I’ve seen from some other developers.  See the reddit discussion of it for comparisons to inotify.  No, it’s not in pkgsrc/ports yet.

Update: And thanks to Thomas Klausner, it’s in pkgsrc as sysutils/entr, and in ports as sysutils/entr thanks to Eitan Adler.  You have no reason not to try it now.

Lazy Reading for 2013/04/14

We are very close to the next release.  As always, it comes down to building third-party software.  Lots of material here to read, until then.

Your unrelated link of the week: A bunch of monster models, all taken at a convention called Monsterpalooza.  A bit grody, but still some very good construction work.  (via)
