Lazy Reading for 2012/02/05


It’s like early spring here in the northeast US.  Which would be fine if it was actually spring.  I miss snow.

  • An explanation of the classic UNIX hierarchy.  (via thesjg on EFNet #dragonflybsd)  I’m behind any explanation that uses the phrase “accretion disk” to describe an organization.
  • Hipster BSD.  If this doesn’t make sense to you, it’s based on this.
  • Would you like to have DNSSEC upgrading explained to you?
  • Hooray for Unicode!  (via)
  • What Commons Do We Wish For?  I was, briefly, technically, an AOL employee after the Time Warner merger in 2000.  I didn’t like the notion of working for a walled garden then, and I think that’s why Facebook and other companies irk me now.  Anyway, read that article for a good explanation of why that feeling is important.

Your unrelated link of the week: Top Shelf 2.0.  A small comics publisher that has put much of their comics online to read.  Their stuff on paper is worth buying too, as I have been doing for a while now.

Book review: The Linux Command Line


I received an email from No Starch Press about reviewing this book, and my first reaction was to say no.  I assumed this was essentially a book about using Bash, and therefore probably not useful to people reading the Digest.

I read it despite my knee-jerk reaction, and I didn’t need to reject it so suddenly.  Almost all of the book will apply to any Unix-like system.

My first real experience with something that wasn’t Windows or a Mac was at a summer job during college, sitting in front of a SparcStation 5 editing files and processing data for real estate.  Much of my muscle memory about vi and file manipulation dates from then.  This book, even though it’s technically for a different operating system, would have been just what I needed.  There’s no system administration in the book, just making your way around a filesystem and the tools you need to get results.  It’s the kind of skills I think people lose out on when they boot to a graphical interface in Ubuntu, for example, and then never experience these tools.

Negatives: a few areas won’t be of use to most BSD users, like the section on packaging, or the bash-centric instructions in the shell programming area.  There’s the occasional off comment, like that OpenSSH originates from “the BSD project”.  There’s surprisingly little of this however, and I had to think a bit to write this negative paragraph.

Positives:  The book puts the proper focus on some complex but rewarding aspects of command line use, like using vi (alright, vim) and understanding regular expressions.  Much of what it covers is the same material I’ve learned to use over time, and explained to others.

There’s clearly two areas to the book; the first half is about using the command line to accomplish work, and the second is about shell programming.  Making it at least through the first half will result in being able to work at a prompt with little issue, with the shell programming a nice bonus.  It’s not the normal mix of admin tasks and introductory text; it’s about working at the command line.  I imagine giving it to new software testers in a lab, or to a Windows user that has to deal with the occasional unfamiliar environment.  There isn’t an equivalent BSD-centric book like this, so it wouldn’t hurt a BSD user, either.

It’s available now at the No Starch website.

Lazy Reading for 12/11/11


Last week was low on links, but this week is great!  I hope you have some time set aside.

  • This article “The Strange Birth and Long Life of UNIX” has a picture of a PDP-11.  I don’t know if I ever actually saw one and knew it before.  (via)
  • Also from the same place: Window Managers Bloodlines.
  • Anecdotal, but probably true. (via luxh on EFNet #dragonfly)
  • nginx is the new cool and unpronounceable web server these days, apparently.  Michael Lucas covers how to transition static Apache sites over to it.
  • This PDF showing slides from the recent NYCBUG presentation by Ike Levy, titled “Inappropriate Cloud Use”, is entertaining, and makes a good point.  Cloud computing is cheap on a per month basis, but since it’s a reoccurring cost, it can cost a surprisingly large amount in the long run.  (via)
  • Hey, a patch for DragonFly (and other BSD) support in Google’s leveldb.
  • Don’t Be a Free User” (via)  The last paragraph is the best.
  • An expanded grep and diff.  ‘grep’ and ‘diff’ have been present for so long, and people understand what they do, generally, that new tools get named after them just because the concept is ingrained in people’s minds.  Note that I said “generally”, as regular expressions can be difficult.  (via)
  • A lot of people don’t realize how they infringe on copyright.  This writeup describes something I’ve seen for years: people think a disclaimer that effectively says “I’m infringing but I’m doing it with the best of intentions” makes a difference.  It doesn’t.
  • So this is what that Xerox Star GUI interface looked like.  You know, the ‘first’ desktop GUI.   (via) Also, there was some advanced stuff in 1968.
  • I like this indicator light setup.  (also via luxh on EFNet #dragonflybsd)  There’s some other interesting old computer stuff at that site too.  I wish there still were computers like these.
  • While we’re talking about old things with a certain feel to them, why not Battersea Power Station?  Here’s some pictures.  (via)

Your unrelated link of the day: Since we’re talking about old things and environments, why not look at some pictures of my workplace?

Lazy Reading for 2011/11/20


Hey, the date’s sorta palindromic!  Sorta.

  • “Bundled, Buried and Behind Closed Doors” – a video description of the physical parts of the Internet.  Remember when MAE-East or MAE-West would have a bad day and half the Internet felt it?  Really, half.  I don’t think I’m exaggerating. (via)
  • Google has a verbatim search mode now, for those of you who regret the loss of ‘+’ as a required search term designator.  (via and also sort of via)  There’s always alternatives.
  • The expr program is a real piece of crap.“  Laser-focused complaining about a small program that’s had 4 decades to improve, and hasn’t.
  • Mechanics for Pure Aesthetics”  The videos are interesting, and I’m linking to this because so much of what I post here and deal with is focused computer work.  Everything is a tool, with a purpose, and a result that you expect.  This idea of machinery or even software having a purpose other than result generation is underexplored.  There’s lots of tools to create art, but there’s little that is art itself.  Even with that general lack, we still get excited when the edge of some sort of aesthetic appeal nudges its way into the materials we use.  You could argue that Apple’s success (for instance) comes from being the one company that consistently thinks about what a product is, instead of what it does.
  • If you use fastcgi, you may need the patch that this blog post talks about.  Also, apache-mpm-prefork is the better choice for Apache on DragonFly.
  • DragonFly mug shot

Your random comic link of the day: Calamity of Challenge.  Also here.  And here.  If this artist’s way of drawing grabs you like it grabs me, he has pages and commissions for sale.

Lazy Reading for 2011/11/13


I’m going for more verbose linking.  Because my opinion layered over a bunch of linkblogging is just what you wanted on a weekend, isn’t it?  If not – too late!

  • NYCBUG posts audio of their regular presentations, and I’m linking to this one by James K. Lowden, titled “Free Database Systems: What They Should Be, And Why You Should Care“.  He was one of the more colorful speakers at NYCBSDCon 2010, so this should be good.
  • It’s Slashdot, so whatever, but this “In Favor of FreeBSD On the Desktop” linked story had a few good comments – BSD hasn’t done enough to differentiate itself from Linux.  “BSD: In Need of a Narrative“.  Or perhaps, “Who cares if it’s clang or it’s gcc – what do you build with it?
  • I read this essay about social networks (via), and the last paragraph is an excellent summation.  Read it, then cancel your Facebook/Google Plus/whatever accounts.
  • Xv6 is a modern version of Sixth Edition UNIX, used at MIT for teaching operating system design.  (via)   The source is available via git, and as a numbered PDF.   The book for the class should make interesting reading.  Oh, you can see the class details, too.
  • FOSDEM 2012 in Brussels, February 5th, 09:00 – 17:00: “Open Source Game Dev”.   Get on the mailing list if this interests you.  Microsoft operating systems still rule the market for games, really, even indie work, so it’s neat to see something that is both open source and game oriented.  There will be BSD “devrooms” there, too.
  • If you are looking for a particular Unicode character (and there’s lots to choose from), Shapecatcher lets you draw what you are looking for and looks for matches.  (via)  I’ve needed that here a few times for people’s names, and it’s fun just to see what comes up from a random scribble.

Your unrelated link of the week: The New Shelton Wet/Dry.  Titles, content, and images are all picked from unrelated sources, but it forms an oddly compelling digest of multiple topics.  Slightly NSFW, sometimes.

Potential job available


A position opened up for a junior systems administrator at my workplace.  You have to be willing to live near Rochester, NY, administrate a mix of Windows and unixy machines, do desktop support, and network management.  (e.g. everything possible)  The work environment is neat, informal, and somewhat adverse.  I’ll have a job description soon, I hope.

This is a shorter version of a Lazy Reading post, but it’s linking to some extensive writing.  Yay for having other people make up for my brevity!

Lazy Reading for 2011/07/31


Posted in the past, for the future.  I always build these up over the week, so if the links seem dated (as in more than 24 hours old), that’s why.  My commentary will add the flavor.

  • This NYT story about Dwarf Fortress has been linked lots of places, but I want to point out the one paragraph:

    Growing up, Tarn was enamored of Dungeons & Dragons and J.R.R. Tolkien, but he has never been a lockstep member of the geek culture so much as a wanderer on the fringes. He didn’t read superhero comics as a kid, and later, he never became obsessed with the “Game of Thrones” books, say, or with “Lost.”

    Are you over 35 or so?  Then maybe you remember a time when there wasn’t a designated ‘Geek Culture’.  It’s something specific to a period in time, like when pay phones were still common, or when people were on average still thin.  It strikes me that the interviewer assumes that a computer programmer should become consumed with a TV media event; that it’s part of what makes them what they are.   It’s as if all accountants need to have brown shoes, and all artists have to wear berets and ‘get’ abstract art.  Maybe I’m just hipster complaining.

  • “...while Bell Labs’ parent company AT&T flatly refused to believe that packet switching would ever work” – Have I linked to Shady Characters before?  I think so.  Anyway, this is part 1 about the @ sign, and it’s of course talking about email and the early days of the Internet, back when it was the ARPANet.  Be sure to check the references at the end of the article; it contains gems like this ad for a 65-pound portable TTY.
  • Tim Paterson has a blog.  DOS is his fault.  Worth reading, for the early hardware details.  (via ftigeot on #dragonflybsd)
  • Removing the Internet’s relics. An article about how FTP should die.  It will…  once there’s no place where it’s needed.  Like gopher!
  • Comparisons like this are usually cheesy, but this one made me laugh: Text editors as Lord of the Rings locations.

Lazy Reading for 2011/05/15


This week: lots more reading!

  • Michael Lucas describes an extra layer of protection for when you can’t force public key usage on every SSH user.
  • Cool, but obscure Unix tools (via)  The screenshots are all from a Mac… How many of the 24 tools listed are in pkgsrc/pkgsrc-wip?   Almost all of them.  (tpp sounds entertaining.)
  • NYCBUG, in addition to having a really fun convention, has been regularly posting audio of the presentations they host.  The most recent is “William Baxter’s NYCBUG presentation on The Unix Method of Development Management”.   See the BSD Events tweet for the download.
  • What Ubuntu means.  (via)
  • Here’s a nice explanation of Intel’s new Tri-Gate design and with it, an incidental explanation of the processor market.
  • This ycombinator post about Hammer2 work has an in-depth comment from Venkatesh Srinivas about DragonFly’s network setup, memory allocator, and token use.  (Ignore the trolling in other comments.)
  • Michael Lucas’s next No Starch Press book is Absolute OpenBSD, second edition.
  • Pictures and video are starting to show up from the just-passed BSDCan 2011. (via this and also thesjg on EFNet #dragonflybsd)
  • My first experience of The Internet was very similar to this.  It should be bizarrely unfamiliar to anyone under 20 or so.  (via)  Get this: I typed ‘exit’ instead of just closing the browser window when I was done messing with it, because some habits cannot be broken.

OSBR: Technology Entrepreneurship


The May 2011 issue of the Open Source Business Resource is “Technology Entrepreneurship“.  You’ll want to read this because it’s all people who are their own boss, using software they can modify themselves.  Seductively nerdy/utopian!  They’re continuing the topic for next month’s issue, so if that describes you and you like writing, here’s your chance.

Daemon and Penguin podcast


Google Search turned up something new: Daemon & Penguin oggcast.  It’s a podcast, with every episode covering something Unix-ish – usually BSD.  Each episode also reviews a horror movie.  It’s not a mix I would have predicted, but I can see how it would work.  The first oggcast has him installing DragonFly.

Update for file(1)


‘file’ has been updated to version 5.05 by Peter Avalos.  file(1) is one of those utilities that I forget is a contributed, external piece of software, even though it’s been in Unix since 1973.

(file is one year older than me!)

Lazy Reading: cheatsheet, disks, pkgsrc, more


Normally I hold this for Sunday, but I’ve got a good batch of links already.  Something here for everyone, this week.

  • A git cheatsheet, and another git cheatsheet.  I may have linked to the latter one before, as it looks vaguely familiar.  Anyway, bookmark.  (Thanks, luxh on EFNet #dragonflybsd)
  • What should you do about bad blocks on a disk?  Get a new disk.
  • If you ever wanted to port software, there’s a pkgsrc developer’s guide (thanks Francois Tigeot) that shows you how.
  • It’s NOT LINUX, for the billionth time.  It’s BSD UNIX (certified, even) under there!
  • Children of the Cron“.  An entertaining pun.  (via)
  • Nothing to do with BSD, or even computers, really: Gary Gorton, interviewed about the recent financial crisis, at a Fed bank website (!?).  Interesting because I like economic matters, and because it’s the first web page where I’ve ever seen pop-up links added usefully, as a sort of footnote that you don’t have to scroll.  (via)
  • Michael Lucas recently had a machine broken into.  Since everything on the machine is suspect, he’s using Netflow data to figure out when it happened, and how, which is not surprising given his most recent book.  He has two posts describing how he backtracks his way to the probable source.

January OSBR: Business of Open Source


The January issue of the Open Source Business Resource is titled “The Business of Open Source”.  The first article, titled “Cost Optimization Through Open Source Software“, explains why iXSystems is all BSD, all the time.  There’s also an eye-opening breakdown of the dramatic cost savings from going with open-source rather than Windows.

Post-install notes


Here’s a nice collection of post-installation notes on DragonFly.  They’re part of a larger UNIX note collection.  I may have linked to it before; I don’t remember.  This note’s new, though.

Less is more, really


If you were dying to have less behave like more, it’s possible to do so with these tips from Oliver Fromme.  I don’t know if it’s that desirable, but it’s an interesting thing.

Horrible accident and other errors


Tim Darby had an error with a particular AMD AHCI chipset, and the entertaining error was:

Attempting to reinitialize the port after it had a horrible accident

This gives me a chance to link to one of my favorite error messages ever.

(The chipset works in current DragonFly, by the way.)

A super-simple install


I was reading this Perl Advent Calendar (that would be good for DragonFly, come to think of it) post about ack, and came across a interesting line:

curl http://betterthangrep.com/ack-standalone > ~/bin/ack && chmod 0755 !#:3'

fetch’ would work just as well on a BSD system. The interesting thing is that it’s a one-liner for installing software that doesn’t make any assumptions about having an existing framework like pkgsrc or aptitude or anything like that – it just grabs the code and plops it in place.  It wouldn’t work for more complex software, but the simplicity is intriguing, to match the Unix-like single, chainable program idea.

For those who haven’t seen it, ‘ack‘ is a grep replacement that automatically takes care of common activities around searching – skipping files that would cause duplicate matches, binary files, etc., handles a larger range of regular expressions, and runs startlingly fast.

Lazy Reading: old UNIX, new book, more NYCBSDCon


A general roundup of things, this week.

  • The 1978 Bell System Technical Journal, describing this new Unix thing.  (via)
  • The book Modern Perl is out, written by chromatic.  I link to it for two reasons: the first is that while the book is available for purchase, it’s also available as a free download, with the only condition that you must tell others about it.  The second reason – and the reason I’d mention this book anyway – is that chromatic writes on his site and for O’Reilly, and his articles are succinct and enjoyable.  The Web is a deluge of text, so any author that can hold your attention, with all the other sources to read, is worth following.
  • More NYCBSDCon 2010 stuff, from the comments on my previous post: Will Backman has partial audio recordings, and Jason Dixon’s adventure is online.  (thanks, Will and Lawrence)
  • This summary of the (BSD-ish) Tarsnap service made me smile.
  • Top 5 Best Practices for an Open Source Development Community.  (via)  I especially agree with items 2 and 3.
  • Oddly compelling.  (via everywhere)

Thanks, chneukirchen.org, for leading me to this.

What of OpenSolaris?


You have probably seen reports declaring the demise of OpenSolaris by now, many taking a less than conservative approach in reporting the news one way or the other. So what do you make of the news? By all accounts, the source code (including future changes) for things such as ZFS will continue to be published under the CDDL. Will Oracle closing up development make it impossible for operating systems like FreeBSD to maintain ZFS without forking it? What do you think the ramifications will be for DragonFly’s HAMMER and DragonFly in general?

I apologize; I’ve been missing.  Here’s some misc links while I get back in gear:

  • A very good reason to be interested in Hammer over ZFS: nobody will threaten lawsuits over Hammer.
  • 10 tricks for admins.  I’m posting it cause I can never remember that thing with tunneling ssh out.  (via)
  • This Gaming Life, as a free download.  An excellent book that is in physical form on my shelf right now.  Yes, unrelated.

Things that are done


There’s a number of things that all came together in the last 24 hours or so, which means: bullet points!

  • Jen Lentfer took my suggestion and ran with it.  He’s got an update to Sendmail 8.14.4 on the way too.
  • Binary pkgsrc-2009Q4 packages for DragonFly 2.4.x/i386 are all uploaded.
  • I finished a build of pkgsrc-2009Q4 for DragonFly 2.5.x/x86_64 – take a look and fix some of the broken items, if that interests you.
  • Weekend reading: check out this Trivium post as there’s some interesting historical items.  I may try that LackRack idea in a environment that doesn’t fit a normal rack well…

The National Center for the History of Electronic Games is looking for tangible artifacts having to do with old text-based games, like Adventure or Zork.  The article includes some history, too.

(This place is in my town, and it’s eye-bleedingly awesome.  I predict that a few years from now, when people realize what this is, it will become a game history Mecca along the lines of PAX.)

More roguelikes: @Play and a new game


Not one, but two roguelike items!  Close your eyes and click randomly if you have no interest in my little obsession.

  • The newest @Play column has more 7DRL coverage, with screenshots and nice little summaries that mention whether a game is fair or not.
  • Also at GameSetWatch, mention of a new roguelike called MnemonicRL, with a video preview.  It’s planned to be a MMORPG, of all things.
Posted by     Categories: Goings-on, UNIXish     0 Comments

@Play: more 7DRL


There’s a new @Play column focusing on more of the entries at the Seven Day RogueLike competition.  I mention this because roguelikes have been around on Unix-ish systems forever, some of these may work on DragonFly, and because they are much more complex and interesting than I would have thought possible.
