Lazy Reading for 2013/03/31

I hope you like reading; there’s some very meaty links this week.  Go get a cup of tea and settle in.  You drink tea, don’t you?  You ought to.

  • Reading about KDE’s repository near-meltdown makes me think we need more checks for DragonFly.  We have the advantage of Hammer, of course, which would help in the same way that the linked article names ZFS as a ‘fix’.  (via multiple places)
  • We know that Apple will reject apps it disagrees with.  Google also will do so.  Has there ever been a program rejected from pkgsrc or (FreeBSD/OpenBSD) ports on content grounds?  Not that I know of – anyone remember differently?  I’d argue that’s a favorable point for the BSD packaging systems, though it may just be that no application has tested those boundaries yet.
  • Portscanning all IPv4 addresses on the planet.  Possibly the largest distributed effort ever?  The detail in the maps and returned services is especially interesting.  (via)
  • Scale Fail, a Youtube video of a 2011 talk about screwing up your services.  Mostly about the humor, but the underlying points are valid.   (via #dragonflybsd IRC)
  • There’s still improvement possible to fsck, apparently based on this.  That’s UFS2 fsck.
  • What is your most productive shortcut with Vim?  A very thorough explanation of verbs, marks, and registers.  Holy cow, I wish I had known about ‘: … v’ before.  It’s long, but worth it.  (via)
  • Matthew Garret’s description of Secure Boot vs. Restricted Boot with UEFI, (via a coworker who went to Libreplanet 2013).  I’m still not sure what DragonFly will need to do about this.
  • I missed mentioning this earlier: 20 years of NetBSD.  We’re coming up on 10 soon.
  • Dragonfly drones.  Unrelated except for name.
  • That guy who starts to froth madly every time BSD is mentioned on Phoronix is still there (see comments).
  • Mainframe computer supercut.  (via)

Your unrelated comics link of the week: Tom Spurgeon of the Comics Reporter asked people for their lists of webcomics that could go in a ‘Hall of Fame’.  The resulting list is a lot of really, really good material.  Go use up a few hours reading.

It’s still snowing in my area, which is unusual.  And great!

Your unrelated comics link of the week: French cartoonist Boulet knocks it out of the park again.

Lazy Reading for 2013/03/10

I managed to come up with a lot of links this week, somehow, despite the start of the class I’m teaching in addition to normal work.  And Summer of Code’s coming up!  And we’re due for a release relatively soon!  I may appear somewhat… stretched over the next few weeks.

Your unrelated link of the week: I’m the Computer Man.  I always thought the mid-1990s were sort of a Internet/computer teenager phase.  Everything had potential but everything was also awkward.  (via I forget, sorry!)

Lazy Reading for 2013/03/03

I am all over the place with links this week – some of them pretty far off the path.  There’s a lot, too, so enjoy!

Your unrelated link of the week: I’ve already been offbeat enough in this Lazy Reading; I don’t have anything else.

Lazy Reading for 2013/02/17

This week I will both post this on the correct day AND get the date in the title correct.

Your unrelated tea link of the week: Epic Tea House Server.  Interesting just because of what he does and because I’ve never encountered tea from a samovar, though I’ve read of it.  (via)

Wait, this is better!  That previous link led to this film from an English chemistry professor about tea chemistry.  At first I was just entertained by his hair and his accent, but when he put tea in a NMR spectrometer, I decided this was the best tea thing ever.  Even better than Elemental!

Pulling authorized_keys from LDAP

Michael W. Lucas has put together a script for pulling a user’s authorized_keys file for SSH out of LDAP.  It’s a very good idea, though he hints pretty clearly that he could use feedback/feedback – there’s already some in the comments.

Updates: from discussion in IRC about this sort of distributed authentication (maybe ‘authentication distribution’ is a better phrase): Tools like puppet or FreeIPA may also be useful.  From seeing other conversations about this, it looks like there’s a lot of solutions to pick from, of varying difficulty, and none canonical.  That’s both good and bad.

Dealing with problematic git upgrades

If you have git installed, and you are trying to upgrade it, you may have problems.  The scmgit-docs package dependency requires some DocBook files that aren’t always accessible.  If you do run into this problem, there’s 3 separate options:

 

New book forthcoming on DNSSec

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.

Holiday Buying Guide

Shopping!  This is the big holiday shopping weekend in the US, and I usually put together something here.

If you have suggestions, please comment!

SMBIOS access now possible

Sascha Wildner has added system management BIOS (SMBIOS) support, visible with kenv, from FreeBSD.  Use it for getting things like the BIOS revision, system manufacturer, and so on.  For example:

smbios.bios.reldate="12/04/2006"
smbios.bios.vendor="Dell Inc. "
smbios.bios.version="2.1.0 "

This may seem minor, but this can be very helpful when dealing with hardware you aren’t physically able to access.

The 3.2 release seems to have gone well.  Who has tried the new USB support?  I’m curious to see how it’s going.

Your unrelated link of the week: This roundup of ultrarealist human sculpture.  You’ve probably seen Ron Mueck‘s art before, at least.

Lazy Reading for 2012/09/09

Whee!

  • deadweight, “Find unused CSS selectors by scraping your HTML”.  I’ve needed something like this for years.  (via)
  • The same sort of thing for pkgsrc: pkg_leaves.  Worth running at least yearly, or at least before any significant pkgsrc upgrade.  There’s no point in updating a package you don’t use or need.
  • GNU Coreutils cheat sheet, plus the instructions to make it.  There’s other cheatsheets linked in the article that may be useful.
  • Compiler benchmarks, comparing gcc and clang versions.  For a complete benchmark, I’d want to compare what number of programs build with each, too.  (via ftigeot on #dragonflybsd)
  • When ‘your mom’ and Unix jokes collide.
  • Distraction-free writing with Vim.  (via)
  • Also, there’s a “Modern Vim” book on the way.  Will it be good?  I have no idea; I don’t know of any prior books by the author or who the publisher is.  Those facts might help.
  • For a known author and publisher, here’s a status report on Absolute OpenBSD, 2nd Edition.  If you don’t know what a BOFH is from his last sentence, read the original stories.
  • Quadrilateral Cowboy, a cyberpunk hacking game that actually involves non-boring programming and not just a pipe-matching game under the guise of hacking.
  • While I’m linking to games, GUTS, sorta like Diablo but more… roguey?  It’s turn-based.  Also, an excuse to use the roguelike tag.
  • 4 UNIX commands I abuse every day.  Having done a fair amount of Perl programming, I am entertained by having side effects being the intended goal.  Also, the author pays attention to what runs on BSD.  (via)
  • Disks lie. And the controllers that run them are partners in crime.”  Marshall Kirk McKusick describes just how hard it is to know when your data has really made it from memory to disk.  (via)

Your unrelated link of the week.  Dubgif.  Random animated gifs and dubstep clips.  Sometimes it doesn’t work, and sometimes it’s perfect.  (via)  If that’s too random, there’s also this .
