In BSDTalk 213, Will Backman talks to a number of people about the FreeBSD Documentation Project. It’s about 14 minutes and it comes from the recent BSDCan 2013 event.
Another week of links completed early. And there’s a lot, so get clicking!
- 1BSD, the installation. Interesting to see the procedure and the tools used.
- Over the Rainbow, polychromatic type from Microsoft. I don’t know if this is as exciting as they seem to think it is.
- Do your own backups. Yeesh, what an unfortunate event. I’m fixing up my backups now, after my own troubles.
- Operating System Development series. Dry but interesting. (via)
- Windowing operating systems are too messy, too restrictive. From 1984. (via)
- Home Automation via the Internet. For those who don’t want to deal with x10.
- Chess implemented in Sed. No en passant? Sheesh, I was on board until that point. (I’m making a joke) (via)
- Managing sshd in Ansible. Ansible’s getting more popular, it seems.
- Remember that PDF compression/scanning error I mentioned a few weeks ago? Xerox has fixed it for their devices, and the patch is available. One of the ways to apply the patch is to print the file to a copier, via LPR/raw. Firmware updates via printing – that seems like a good and bad idea all at the same time.
- An XKCD cartoon slightly related to the previous link.
- Learn to code. (via)
I need to update this post during the week as I see stuff, or else I spend an hour rushing to get it all together before Satuday. I need to start watching PC-BSD src changes, too.
- DiscoverBSD has a recent BSD roundup, too.
- EuroBSDCon registration is 20% off but just today.
- Using 6rd in OpenBSD.
- FreeBSD has imported the Radeon KMS driver.
- FreeBSD’s mfiutil has JOBD support.
- FreeBSD has ARMv6/7 superpages support.
- FreeBSD supports the PCI-E SSD in the Macbook Air. (It needs separate support?)
- FreeBSD has updated support for Centrino 2200-N wireless.
- FreeBSD has a speedup in madvise calls.
- FreeBSD is using PCIDs on Intel chips to reduce process switch latency.
- NetBSD has the start of a potential lint replacement, called ‘mint‘.
- NetBSD supports the BCM57762 and BCM57765 chips, for Thunderbolt <-> Ethernet.
- OpenBSD has support for more ciss(4) devices, via FreeBSD.
- OpenBSD has updated to pixman 0.30.2, DejaVu Fonts 2.34, libX11 1.6.1, and xterm 296, and added ipv6-toolkit 1.4.
- pkgsrc nearly has a signed packages mechanism.
avalon.dragonflybsd.org, also known as mirror-master, is the final dragonflybsd.org system to be moved into the new colocated blade server. Your downloads of binary packages or DragonFly images should be speedier.
Remember my recent disk issues? As a side effect of protecting myself, I have a good example of deduplication results.
I have a second disk in my server, with slave Hammer PFSs to match what’s on my main disk. I hadn’t put them in fstab, so they weren’t getting mounted and updated. I got them re-created, but they were nearly full. Here’s an abbreviated df, from which you should be able to tell which drives I have :
Size Used Avail Capacity 929G 729G 200G 78% /slave/slavehome 929G 729G 200G 78% /slave/slavevar 929G 729G 200G 78% /slave/slaveusr 929G 729G 200G 78% /slave/slaveslash
That 78% is how full the Hammer volume was. I turned on Hammer deduplication, since it’s off by default. The very next day:
Size Used Avail Capacity 929G 612G 318G 66% /slave/slavehome 929G 612G 318G 66% /slave/slavevar 929G 612G 318G 66% /slave/slaveusr 929G 612G 318G 66% /slave/slaveslash
It’s a 1 terabyte disk, and I gained more than 10% back – That’s 100g of disk space that I gained overnight. There might be more tomorrow, given that it was all of 5 minutes of dedup work.
This won’t surprise you if you’ve seen previous deduplication links here, like my previous results or some real-world tests. It’s still great. I’d suggest turning it on if you haven’t – hammer viconfig the appropriate PFS and uncomment the dedup line.
Only 3 more Mondays left in the student work part of Summer of Code! Unsurprisingly, it seems the students are mostly in the cleanup phase – as it should be.
I’ll be working on the 3.4.3 release of DragonFly within the next 24 hours, and it should be available this week. I’ll have a list of the bugfixes it contains…
This week, I’m opinionated on every link.
- An 80s computer ad that got almost everything correct. It used to be sci-fi environments were super-clean – now they’re dirty, with ubiquitous electronics. That’s something that could be picture-blogged to prove, but I ain’t doing it.
- Bunnie Huang does “exit interviews” when he stops using equipment. Given his electronics knowledge, he goes into a lot of detail, including pictures through a microscope. Speaking of this, how has my ancient HTC Incredible survived 3 years of trips into a salt mine? I don’t know.
- InterTwinkles, open source group decision making software. Don’t know how well it works, but it certainly seems like the right idea. (via)
- Turning the Apple //e into a Lisp machine, part 1. They don’t actually get to the Lisp machine part, but it talks about how Apple computers could load data through the audio jack. I remember doing that with a tape player, too. It sucked. (via)
- kOS. It’s so minimal that I am not sure what it can do or how to use it, but it’s also so minimal that I’m sure there must be something to it. (via)
- Building a Chording Keyboard. I’ve mentioned the Microwriter and Twiddler before, but this article goes into a lot of detail about the actual construction of a home-made unit. (also via)
- Book review: The Healthy Programmer. It may or may not make you exercise, but it will make you feel a little guilty about sitting and reading the web like you are doing right now.
- Hyphen, en dash, em dash, minus. So few people know there’s a difference. (via)
- ASCII Art. History of, examples, and so on. (via, with video)
- Five Useful Git Tips. Git tips come up all the time, but this one is interesting because it’s using “showterm“, which lets you make text-based animations? movies? to show a work process in a terminal. I think I may have linked to something similar before, but this is good.
- How to Avoid the Emacs Pinky Problem. A neat idea, but some of the suggestions are actually going to make it worse. (via)
- Vim: revisited. Decent ideas, and the links at the end are good further reading. There, I’ve posted on both sides of the editor issue. (via)
- The problem with Vim. (via)
Your unrelated link of the week: the Scary Godmother Doll. One of my favorite illustrators, building a doll. I met the creator years ago in Pittsburgh; she is an astonishingly energetic person.
I hope I’m catching the interesting stuff; I’m only reading the src changes.
- A talk about pkgsrc at a YAPC conference.
- FreeBSD has improved parallel read performance by changing how locks work.
- FreeBSD has enabled VFP in QEMU. No, I don’t know what that means.
- FreeBSD has upgraded to BIND 9.9.3-P2.
- FreeBSD has imported NetBSD’s libexecinfo-20130822.
- FreeBSD has imported OpenBSD’s vmx(4) VMWare network driver.
- FreeBSD has upgraded to ACPICA 20130823.
- NetBSD has added ‘multigest’, for calculating multiple digests in parallel.
- NetBSD has updated to Postfix 2.9.7.
- NetBSD now supports the Intel Centrino Advanced-N 6235 Wi-Fi controller.
- OpenBSD has updated a number of x* utilities in xenocara, including xserver.
If you’re curious about the hardware being used for the colocated dragonflybsd.org servers (this includes the website, the repository, the mailing lists, dports build machines, etc.), here’s the ‘MicroCloud’ product page. DragonFly’s model was purchased from iXsystems. Apparently those Haswell processors have a fantastic power consumption to performance ratio. (via)
Had this one done before the last Lazy Reading. There are so many things to see and think and do in a day, and they’re not even all on the Internet. You get only the Internet ones here, though.
- Slashdot founder Rob Malda on why there won’t be another Hacker News. Found on Hacker News, of course, and I suspect the title was designed to get clicks from there. Some interesting thoughts on how people read.
- Facebook is like a television that monitors to see how much you are laughing and changes the channel if it decides you aren’t laughing hard enough.
- Unix routing. It’s actually Linux routing, but if you avoid the Linux-specific parts, it’s a useful introduction.
- ASCII cheat sheet.
- How to build a user-level CPU profiler. Followed by Hacking the OS X Kernel for Fun and Profiles.
- Mediagoblin. I haven’t tried it, but the idea is a good one. As long as we don’t have to call it GNU/Mediagoblin.
- I was going to make a joke about not using software I can’t name out loud without sounding incomprehensible, but then again, I’m using BSD. Too late for that joke.
- The Future of Programming. Take the time to watch this. The list of resource links is enough to fill several afternoons with reading. Also, it’s not yet another TED talk where someone is trying to communicate excitement rather then information. (via)
- If I’m going to link to Reggie Watts, why not look at one of his music videos? Normally that would be an Unrelated Link, but I just made it related from the previous item, yay! (link contains naughty language.)
- Go for system administrators. (via)
- Git + webcam = lulz. This could be fun or scary or both. (via)
- Retro video games, delivered. (via) I still hope to build a MAME box someday.
- 0.9999999999 repeating = 1.
Your unrelated comics link of the week: Boulet’s Long Journey. Get ready for a lot of scrolling. I know there’s a lot of really good French comics that I don’t see just because I don’t speak the language. (This one’s in English, but the cartoonist is French.)
Not just source links, this week:
- OpenBSD no longer has the Y2038 problem.
- A head-mounted augmented reality display using FreeBSD?
- The 2013 EuroBSDCon is going to have a vendor summit (primarily FreeBSD, from the sounds of it).
- There’s a new BSD Certification Group training CD.
- NetBSD now supports the Sitecom N300 wifi adapter.
- Do you have an Amiga that runs NetBSD, and an X-Surf 100 network card? It’s supported.
- nvi now has multi-byte character support, at least on FreeBSD.
- The July FreeBSD Foundation newsletter has a “Strategic Planning” section that I can’t imagine anyone would disagree with. The goals expressed – experience, design, and documentation – are all things that each BSD project can do better than Linux or most any other open source system.
One of the most-requested items for the DragonFly mailing list archives is reverse sorting by date. Mailman, which is what’s being used now for archiving, doesn’t have a ‘native’ way to do that. Has anyone seen a trick/patch to get that to happen? I already patch Mailman to get the message date to show in listings.
Michael W. Lucas has a review up of Richard Bejtlich’s “The Practice of Network Security Monitoring“. Both of them are long-term BSD users, and Bejtlich, if I remember correctly, was part of the design of Capsicum, the security framework that is serving as a Summer of Code project for DragonFly right now. So it’s worth looking at his book. And/or looking at his blog, for those who want more.
I’d be really surprised to find this affects anyone, but it’s possible: some kernel options specific to Cyrix processors have been removed, by Sascha Wildner.
I think that is the same location where I went to a rather spectacular pre-dotcom-crash presentation from Time Warner/Road Runner back in 1999. The hotel was great; the presenters were befuddled. An internal account manager ran up a $3,000 bar tab in one night on a company credit card… I still have the fancy Guinness glass he bought me. I don’t think this convention will work exactly the same way, but unlike my 1999 trip, the speakers at this one will actually know what they are talking about.
If you look at the reports from students this week, they are mostly “I had bugs and I fixed them and there’s not much to do other than test”, which is the sign of well-planned projects. Here’s the status reports:
shiningsilence.com suffered a disk failure early this morning. I’ll take the opportunity to set up a new machine, given that my local backup drive hasn’t been mounted and my remote backup went offline, in a horrible coincidence.
The disk is up and limping, which is why you can read this, but I’m still rebuilding. What motherboard/CPU/RAID/etc. parts do people recommend?
Again, lots of links. Some of these are overflow from previous weeks where I just said “That’s enough; let’s work on the next Lazy Reading.”
- Perl, the Detroit of scripting languages. The slides are entertaining, but it’s also interesting for the discussion of how to handle a very old code base and a community. (which are BSD issues too) (via)
- Ruins of Forgotten Empires: APL languages. ”APL uses one thread per CPU, which is how sane people do things.” (via)
- Remember when we used mega- prefixes to measure disk and memory, and not bandwidth?
- Ian Lance Taylor’s 20-part series on ELF linkers and linking. (via EFNet #dragonflybsd)
- PDF compression formats. Incidentally, here’s an answer on the Xerox number alternation issue, where compression means one number gets misidentified and substituted for another. The Economist has a not-crazy take on it. It’s not a Xerox problem but rather a JBIG2 compression issue. I have a number of Xerox models at work and have not seen this issue, but also haven’t checked for it.
- OSI, the Internet That Wasn’t. People only ever care about levels 1, 2, 3, and 7 in the OSI model. And this joke. (via)
- The Toshiba Libretto. You can get more powerful, smaller computers now, but they’re cheap netbooks and totally uncool.
- A crash course in tmux. (via)
- Whatever room you keep your primary computer in – clean it, please.
- Robots for destroying buildings. This is not some speculative article; these are robots you can buy right now. Screw the flying cars joke everyone makes; the future is now. (via)
- How to shutdown computer under Linux? A rough summary of how Linux can be a moving target for actual usage.
- Vim 7.4 out, mostly so there isn’t so many patches to apply.
- Goto is making a comeback. (via Eric Radman)
Your unrelated link of the week: Mighty Taco radio ads. Mighty Taco is a Mexican fast food place from Buffalo, New York, USA. It’s about as authentically Mexican as fast food from a city on the edge of Canada can be, which is ‘not much’. I’ve always loved the food, though, and the commercials are just the right mix of amateur joke and commercial advertising.
Or at least scheduled to happen now, since I’m posting this and postdating it for everyone as a reminder. I hope I have the time right.
The mailing list archives for DragonFly (lists.dragonflybsd.org) have been moved to new hardware. (Yay!) The patch that actually shows date in the listings needs to reapplied, cause Mailman is somewhat stale. (Boo!) I applied the patch and I’m regenerating all the archives now. (Yay!) There’s some garbled messages in the archives that cause a bunch of “no subject” partial messages to be dumped at the end. (Boo!) I’ll manually fix them if I can, someday. (Yay?)
Definitely Saturdays for this summary. In other BSDs this week:
- It’s FreeBSD, but it can apply to any BSD where a personal attribution license is used: Julian Elischer’s name comes with every iPhone.
- cxgbe(4) cards can now display their temperature under FreeBSD.
- ciss(4) supports additional HP RAID controllers under FreeBSD.
- Bind has been updated to 9.8.5-P2 in FreeBSD.
- FreeBSD has initial support for the Cubieboard 2.
- FreeBSD now has a USB test program.
- NetBSD supports some additional ZTE modem devices.
- NetBSD has cgram, a substitution-cipher solver. For amusement purposes?
- NetBSD supports the Nuvoton W83795G monitoring device.
- OpenBSD now supports wireless devices using the Ralink RT3060.
Wired has an article up about Jordan Hubbard and his move from Apple to iXsystems. It’s not a bad article, though it doesn’t delve into the why of BSD very much. In any case, iXsystems has been really bulking up lately to be more than a generic hardware provider.
Speaking of which, that blade system going in now for dragonflybsd.org was sold by iXsystems.
Michael W. Lucas’s next topic in his Mastery series is ‘Sudo‘.
Everyone passed their Summer of Code midterms! Not that this was a surprise; all the students have been consistently working and overcoming problems, but a 100% pass rate makes me happy.
Here’s the status reports:
On August 10th, Michael W. Lucas will be giving a talk on DNSSEC to the Metro Detroit Linux Users Group, and it’ll be livestreamed for everyone to see. His talks are energetic and entertaining, and it’s worth making time to see.
Joris Giovannangeli, one of the Summer of Code students for DragonFly, posted his thoughts on credential descriptors – have a read. He is working on capsicum and DragonFly, so this is a natural thought process.
These have been very easy to create over the last few weeks; there’s been a torrent of reading. Can I say torrent without making it sound like this is all downloaded large files? The word is overloaded. Anyway:
- How emacs changed my life, from I think the creator of Ruby. (via)
- Autodesk uses Creative Commons right.
- British kids in the early 80′s, using computers. Might induce nostalgia for some.
- Forth – The Early Years. (via)
- The Collapse of the Animal Crossing Economy. I am entertained by the intersection of games and economics. (via)
- Tagsistant, a tag-based filesystem. Works via command line, which is unexpected. (via Tim Darby on users@)
- Git and GitHub Secrets. (via)
- IE vs. murder rate. Correlation, rather than causation, but still funny. (via)
- toybox, a BSD-licensed command line environment for Android. I mentally said “so what?” until I saw the “Why is Toybox?” presentation. It’s an excellent talk that makes a sequence of good points about many topics on licensing and utility, and I recommend making time for watching it. (first link via)
- The Confused Deputy, an explanation of capabilities. (via #dragonflybsd on EFNet)
Your unrelated link of the week: What goes on when you are not there!
How many tags can I fit on this post? I think I’ll aim for Saturday for these BSD catchup posts. In theory, I can prep this and the Sunday Lazy Reading posts ahead of time, since they tend to be all-week items, and have the whole weekend covered.
- BeagleBone systems are getting popular.
- Distributed chrooted pkgsrc bulk builds. Very necessary documentation.
- …And a script to do all the setup for those builds.
- The VBSDCon site has more details on the upcoming convention. (via)
- The cxgbe(4) device has hardware dedicated to sniffing packets?
- FreeBSD has switched to the BSD-licensed version of patch.
- FreeBSD has an updated ACPI implementation.
- FreeBSD is importing OpenBSD’s rsu(4) wireless Realtek driver. Needs firmware.
- What’s new in pkgsrc-2013Q2. With screenshots!
- NetBSD now supports 2 new Centrino Wireless-N devices.
- NetBSD now has BIND 9.9.3-p2
- PHP 5.5 has hit pkgsrc.
If you have a computer with one of the very-very-new Haswell processors from Intel, Matthew Dillon has made some changes that will interest you. They shave off (in the example given) about 20% of CPU power usage without much effect on performance.
killall -T will now kill all processes associated with the current tty, except parents of the killall process itself. It’s a shortcut to “kill all these runaway items I started by accident”.
Thanks to the effort of a number of people, DragonFly (-current) now supports KMS and accelerated video on Intel 915 chipsets. It’s 2D and x86_64 only for now, but it’s much, much better than just using the vesa driver.
Every year, people ask “Why can’t writing documentation be part of Summer of Code?” (Not necessarily for DragonFly, but in general) Google has a “Doc Camp”, where a whole lot of documentation gets produced in sprints, and anyone can participate – not just Summer of Code students.
If this sounds interesting to you, your application has to be in by August
7th 9th. (URL and date updated)
Please welcome our newest DragonFly committer: Johannes Hofmann. He earned this by coming up with a significant chunk of DragonFly’s upcoming KMS/915 support, and it’s now easier to just have him work directly than to be constantly committing for him.
It’s week 6, I think, and the midterms are coming up. Here’s the status reports:
Since there’s a newer set of dports binary packages uploaded, I thought I’d spend my weekend upgrading, to catch up.
And that was it. Well, not really. I had to dump and restore my Postgres databases, cause of the switch from 9.0 to 9.2 as default. I had to build php5 from source to get the Apache module. Those two things together took longer than the entire download and upgrade of the rest of my system – some ~200 packages?
Michael W. Lucas wrote a blog post about pkgng and Ansible on FreeBSD. Will it work on DragonFly? We already have pkgng on DragonFly in the form of dports, and Ansible… might work? Please, someone try.
So many links came up recently that I had already finished this week’s entry when last week’s Lazy Reading was posted.
- The FatMac cooler. Cooler as in place to keep drinks cool.
- I always like seeing what people use for home BSD hardware.
- Note the embroidered dragonflies.
- Early mobile and video phones. Decades early. Look at the slideshow.
- Looking for evil in your firewall logs.
- Best Open Source games. Dunno how many work on any BSD. (via)
- The 2-clause BSD license and the ISC license are considered functionally equivalent?
- The GREP test, an excellent standard for code. (via)
- What if your klacky keyboard is too klacky? (also via)
- Soldering is Easy, the comic book.
- People are really starting to pile on Microsoft. (I already started) Unix-like systems are resuming their dominance of the market. Maybe ubiquity is a better word?
Your unrelated link of the week: Release the Kraken!
In part of a long thread about dports packages on the users@ list, Matthew Dillon notes that a new set of packages for i386 and x86_64, for 3.4 and for “3.6″ (meaning bleeding-edge DragonFly, even though that’s numbered 3.5) is mostly uploaded. He also notes that a Haswell-processor-based blade server for DragonFly is in the works, so much of the dragonflybsd.org infrastructure is going to move from his house to a datacenter, with the benefits that provides. It’ll also help automate binary package building.
Sepherosa Ziehau added SO_REUSEPORT to DragonFly. I don’t know how the mechanism works, because he didn’t include a description, but he did include a explanation of just how much it reduces CPU usage during as-high-as-physically-possible network load. He even wrote tools to test it more heavily.
Here’s what jumped out at me from reading source change mailing lists:
- pkgsrc now has Ruby 2.0.
- NetBSD now has wpa_supplicant and hostapd, and dhcpcd 6.0.3.
- NetBSD supports Nanjing QinHeng Electronics devices via puc(4). No idea what that is.
- NetBSD also supports Intel 8 Series SMBus devices, which I mention just because finding the right drivers for SMBus devices always frustrated me on Windows.
- NetBSD’s hostname has some new options.
- FreeBSD supports Coleto Creek devices: SATA, SMBus, and Watchdog. Not sure if that’s a brand name or a special type of construction. Also, AR934x and the Qualcomm Atheros DB120 development board, and the Broadcom BCM5725 network controller.
- OpenBSD now has sshd supporting encrypted host keys. I can’t find an open mail archive with OpenBSD source-changes as an archived list, so I don’t seem to be able to link to it directly.
I’m going to have to set a specific day of the week aside for these.
The Observe, Hack, Make 2013 festival is coming up at the end of the month in the Netherlands. Unfortunately, it’s already sold out, but there’s going to be at least one DragonFly developer there. (credit to Matthias Schmidt for letting me know about the festival)
The July issue of BSD Magazine is out, and the listed theme is “Security and Cryptography”, but there’s plenty else.
I’m late for this, even though the students weren’t. Mea culpa! There’s been a lot of discussion on IRC, in EFNet #dragonflybsd, between the students and various DragonFly developers.
Last week was relatively light, but somehow this week I read a zillion interesting things. It’s been too dang hot to do much else, other than flop in a chair and point a fan at my head.
- Chopping up CSV files. Tabular format will never die, and for good reason.
- Reanimated: The story of Vampire: The Masquerade Bloodlines. I like this idea that someone can just keep working on a project long after the originating company disappeared, just to improve it for their own benefit – no mention of open source or even a plan for it. See also Oblivion Lost or Complete for some of my personal game fix/improvement modification favorites. (via)
- I don’t think this systemd/Debian news is accurate in its reasoning, and they don’t say what’s going to happen with non-Linux Debian. However, it’s still crappy, any way you slice it. (via)
- The paranoid #! Security Guide. Lots of details that won’t necessarily apply to your BSD system, but the descriptions of various attacks are neat. (via)
- Another reminder of how easy it is to deal with a lot of text data at a Unix-ish command line. (via)
- Those ssh password attempts are still going, and have been for a decade. (via)
- Don’t care about the story, but I like the dragonfly illustration.
- Linus Torvalds swears a lot. The problem is not ‘office politics’ as he sees it, but that if you swear all the time as the leader of a project, it becomes commonplace. Linus really has to really freak out for people to notice something new. There’s other issues, like how other people emulate the behavior, but I’m pointing out the ‘verbal base sweariness’ of a project affects the entire tone.
- Quine Relay, where programming languages write each other. The Ouroboros illustration is appropriate. (via many places)
- History of emacs and vi keys. I like how this shows that the command styles in both editors was shaped by the available hardware. (via)
- Fear and Loathing in Debian^H^H^H^H^H^H/Ubuntu (or: who needs /etc/motd). A wonderful rant about the creeping complication of operating systems. Let’s place bets on when people start complaining about Linux bloat. (via luxh on EFNet #dragonflybsd)
Your unrelated link of the week: Bones Don’t Lie. An anthropologist who blogs about various discoveries of human remains. I really enjoy blogs where someone is talking about a subject they care about – not to sell a product, not to be paid (directly), but just because they like the topic and they want to share it with others. Of course I would think that, wouldn’t I?
Thanks to the efforts of a large number of people, KMS support is showing up in DragonFly. This supports accelerated video on the new Intel graphics chipsets that seem to show up on many recent laptops.
I made a hesitant attempt to keep an eye on other BSD source changes over the last week. I complain about needing coverage for the other BSDs, so I’ll see what I can do:
- (Parts of?) full-disk encryption support in NetBSD.
- esp (the SCSI board) support for NetBSD/acorn.
- SipHash support in FreeBSD
- SYN Cookie support in FreeBSD.
Busy, busy week.
- An in-depth programming language comparison. These can be fun for reinforcing your language choices, but also interesting just for the depth of comparison. Spoiler: Java can be crazy slow; Perl can be crazy fast. The page has lots of charts which always make me happy. The quotes at the end per-language are enjoyable. (via ferz on EFNet #dragonflybsd)
- PC-BSD is using a content delivery network for their image delivery – that’s a good idea. It’s very hard to get people to consistently use mirrors, even if they are consistent and local.
- A Statistical Analysis of Nerf Blasters and Darts. Nerf guns are fun, charts are great, so that whole article is the bestest. (I think via)
- 1,200 computer interfaces from the movies. See this link for the story, and this link for more details and some new interfaces to that huge quantity of visual information, about visual information.
- 80′s childhood. It’s linkbait, but I like the sort of burst of how personal electronics looked at that point in time.
Something new and odd: A port of the Hammer (1) filesystem into Go, for go-fuse. As the author has said, it’s more for the practice of learning Go and Hammer than for producing anything useful. Still, an interesting way to learn.
Encryption seems to be the accidental theme tonight. A question about Hammer 2 and encryption prompted this list of possible solutions from Matthew Dillon. Hammer 2 is still months out, so these features both require time and someone interesting in doing them – though they sound quite possible.
Still not sure if I should be writing Hammer or HAMMER.
If you were wanting to encrypt your /home directory, Pierre Abbat has written up the explicit steps he took to do that very thing.
Week 3 is underway, and the students are starting to get into the meat of their projects:
The pkgsrc-2013Q2 branch has been out for some days, but the official release announcement has now been published, with details on the number of ports. You should be able to pull it down from dragonflybsd.org via git, by the way.
A U.S. holiday and very warm weather has made this a less intense week. At least for links.
- Someone help. A problem I never anticipated. (via)
- Git Cheat Sheet. This one’s for printing. (via)
- Real Life Tron on an Apple ][gs. (via)
- Neocities, an excellent idea. Follow the suggested links. (via)
- Mandelbulber, a cross between Electric Sheep and Xaos. (via I forget)
- A drawing of the Internet (ARPANet) in 1977. The whole thing. (via)
- Bunnie Huang’s making an open laptop. Won’t be cheap or easy, but it’s still neat.
- Vim 7.4a hits beta.
Your unrelated link of the week: A new Cyriak-animated video, this time for the band Bloc Party.
The official announcement has gone out. You should be able to pull pkgsrc-2013Q2 via git from dragonflybsd.org within the next 24 hours.
While these aren’t his BSD books, Michael W. Lucas has an interesting post up about the sales on his two recent books, SSH Mastery and DNSSEC Mastery. I’m always interested in seeing how self-publishing models work, whether it’s software or books or music. He points out that the point of his DNSSEC book is to see if a very difficult subject can be covered in a book like that – which it is. There’s very few published books that go that in-depth.
(I’m hoping for a whole “Mastery” series covering topics other writers don’t, especially in a BSD-friendly way.)
All the Summer of Code students for DragonFly have posted their second week reports:
- Daniel Flores: HAMMER2 compression feature
- Larisa Grigore: System V IPC in userspace
- Pawel Dziepak: Make vkernels checkpointable
- Joris GIOVANNANGELI: Capsicum
- Mihai Carabas: hardware nested page table support for vkernels
There’s a lot of progress for the second week, which is wonderful!
Some of the links this week go pretty in-depth. Enjoy!
- This short story from 1954 might serve as a reason to avoid single system image computing… (via Sascha Wildner)
- Vim and Ctags tips and tricks. (via)
- Psygnosis game box designs. Nostalgia for some, neat art for anyone else. (via)
- 50 years of ASCII, and here’s the table it comes from. Some other neat links there, too. (via)
- Richard Feynman and The Connection Machine. If you like stories about Feynman, who was a very interesting person, you may want to read Feynman, the comic book. I met the writer, Jim Ottaviani, years ago, and he was very energetic about both science and comics. Look up his other work if that sounds interesting – which it should. Here’s a sample from the Feynman book. (via)
Back to the Future: Preserving the History of Video Games. This is right around the corner from me. The game museum is as neat as it sounds (yes, they have games out to play), but the article doesn’t mention that it’s attached to a fantastic and huge kid’s museum.
- Building a Cray at home. Similar to this previously-linked idea. (via)
Your unrelated link(s) of the week: Candy Box and A Dark Room. Both are text-only games, but they use HTML5 for animation. They start minimal, and build up – be patient; there’s a lot of gameplay in there. These minimal games fascinate me. It’s like reading a book, where it goes from just static text to an entire world being built. (somewhat via)
Your bonus unrelated comics link of the week: Jack Kirby double-page spreads. It’s not an exaggeration to say this artwork crackles. (via I forget)
Earlier this week, Daniel Flores posted the first-week report on his Google Summer of Code project, file compression in Hammer. He mentioned that the LZ4 algorithm he is using seems to have the best performance with repeating text data, as in logfiles. I asked for numbers, and he provided them. The important data in the results is the total compression column. It shows how many 64k blocks were able to be compressed, with that type of data.
