John Marino has created something very useful: a graphical tool for Hammer file history. It’s called ‘Slider’, and it uses curses to work in a terminal. It shows historic versions of files and can restore those old versions as needed. This was already possible in Hammer, of course, but it required a sequence of commands t [...]
I’m going to dive right in with an anecdote: As is normal for anyone in systems administration, I’m busy at work. I’ve been short an employee for some time, and I brought in a managed service provider to do some work. This included a revamping of the network equipment and layout, as it has been growing organically rather t [...]
Last of the year! Glitches: A kind of history. (via) Speaking of glitches: Breaking Madden is still going. First Commits. (via) Your Friendly North Korean Network Observer. (via) The SoftSel Hot List for 1986. Steel Mill Hacked. How long until having operations disconnected from the Internet becomes a sign (Read more...)
The list is shorter this week; I blame the Christmas holiday. OpenBSD now has position-independent executables for some architectures. That may mean changing your upgrade strategy. (5.6 upgrade guide here) FreeBSD now has frequency/voltage control on the Raspberry Pi. There’s a lot of v7 ARM architectures. I can see why people are w [...]
BSDNow isn’t slowing down for Christmas, cause there’s a new episode up. There’s two interviews this time – Erwin Lansing, about BSD in Europe, and Cristina Vintila, about BSD conferences. The rest of the episode is a bunch of “How did you get into BSD?” stories from viewers, both in text (i.e. read out f [...]
One way to keep file history on an very active Hammer disk from eating up all the space: more snapshots. This may seem counterproductive, but disk pruning eliminates historical data between snapshots, so you can keep older data at the cost of some temporal accuracy.
As part of another thread, Steve Petrie posted an in-depth description of how and where and why he’s using DragonFly. Worth looking at either for workflow tips or for just seeing the use case.
BSDTalk 249 is an 11 minute interview with Scott Long, who is involved with Netflix’s FreeBSD-based local caching appliances. This conversation is from MeetBSD 2014, though I heard Scott talk about the same subject at the last NYCBSDCon – it’s an astounding amount of data flowing through those machines.
I am slightly confused about which day it is. Dinosaur’s Pen, excellent old technology pictures. (via) Ultima Ratio Regum, a roguelike walking simulator in development. Currently Windows-only. 2014 Cacowards winners. These will probably run on most any BSD with a Doom port. (via) Effectively Managing Memory at Gmail Scale. All the [...]
I sort of lost a day this week because of an accidental 20-hour workday, but I still have the links: I love cross-pollination. (plus) “Why I (mostly) hack on BSD licenced stuff: so I don’t have to deal with this.“ Tips on pkgsrc packaging. Kerberos IV is going away in pkgsrc. The pkgsrc-2014Q4 freeze (Read more...)
BSDNow 068 has a large number video links to various BSD conference videos, a bunch of other article links,, and an interview of Michael W. Lucas about his new FreeBSD Mastery: Storage Essentials book.
From a question about mixing in a SSD and a very slow disk: swapcache can make things better, though I suggest other crazy arrangements.
If you really, really want to make sure you aren’t pulling in any parts of X when installing dports, and you’re building from source, there’s a few options you can set to keep X11 off your system. You can even go farther.
I had to type it that way because it rhymes. Sascha Wildner has committed an IPMI driver port, tested/watchdogged by Markus Pfeiffer. What’s it do? It’s a machine management standard.
Minimal link text this week. It just happened that way. random in the wild Best Unix time-savers Where apps end and the system begins. The password? You changed it, right? Live network attack map.

Get ready for some reading. There’s some packages moving from pkgsrc-wip to pkgsrc proper. pkgsrc-2014Q4 branching is planned for Monday the 15th. PC-BSD now has an automatic package/security patch upgrade mechanism. Steam on PC-BSD. Holy grail, there. PC-BSD needs testers for the new Update Manager, for moving from 10 to 10.1 NetBSD [...]
It’s possible, if you are several releases (years) behind, to end up with a DragonFly system that can’t compile and install the current release, due to incremental changes over time. It’s rare, but it could happen now between, say, version 3.4 and 4.0. The usual solution would be to incrementally upgrade in order, which is [...]
If you want to help I/O performance when DragonFly is virtualized, here’s a short checklist of what to work on. I haven’t noticed any problems – but I’m not taxing any of my VMs that heavily.
BSDNow’s episode this week focuses on the just-released Bitrig 1.0, and has an interview with Patrick Wildt of that project. There’s also coverage of other topics, including the new poudriere release – that’s the tool that bulk builds packages for DragonFly and FreeBSD, though I don’t know if it’s unified [...]
bycn82’s rewrite of IPFW2 is available as a git branch to try out; he’s posted the link. Please try, especially if you are still working with the original ipfw.
