Revealed: the amazing cover for Walkaway, my first adult novel since 2009

Posted By Cory Doctorow

Next April, Tor Books will publish Walkaway, the first novel I’ve written specifically for adults since 2009; it’s scheduled to be their lead title for the season and they’ve hired the brilliant designer Will Staehle (Yiddish Policeman’s Union, Darker Shade of Magic) for the cover, which Tor has just revealed. Staehle’s cover features a die-cut... more

The next mass murderer?

Posted By Greg Lehey

We're used to the occasional flame that still goes through the FreeBSD mailing lists, but today I saw one that really worried me. Here a couple of excerpts: You could pay for me to visit you. If you are right, then there is no reason for you to worry. If you are wrong, then you will have no idea what I may or may not do to you. You are not bullet proof nor are you stab proof. I am excellent with crossbows and bows and arrows.

NBN satellite: doesn't pass muster

Posted By Greg Lehey

Phone call from Barbara Hammond in Fairhaven today. She had read my Why you don't want NBN satellite page, which was really intended for people in Dereel. It seems that she is currently connected to the net via ADSL, and she has now been informed by the National Broadband Network that the Sky Muster" satellite is available. Most of Fairhaven is earmarked for FTTN, but it seems that her location is just outside the limits. And now she's concerned that she will lose her ADSL. Should she be concerned? Yes, most definitely. She uses a lot of data. She doesn't know exactly, but it looks as if she is paying TPG $80 a month, which would match the 300 GB Off-Net package.

DoS?

Posted By Greg Lehey

Seen on IRC this morning: <callum> Hmm, I'm getting no response from www.lemis.com <chuzz> Isn't it wwww.lemis.com? ;) <pez> www.lemis.com not working for me That can't be right. www is my external web server, and it's a model of stability. But it was. ping worked fine, but the ssh I had to the system didn't respond. Neither did a page load attempt. How do I access the console on the machine? I've almost never needed to, and it took me quite a while to find out how.

Revisiting OpenBSD and NetBSD

Posted By Greg Lehey

Glenn Mawby was asking some questions regarding proxies on IRC today. He's running OpenBSD, which could differ from FreeBSD in that respect. But I don't have an OpenBSD box any morein fact, it has been over 6 years. Now I have virtual machines, so it's trivial to create one and run OpenBSD on it. Downloaded the install CD and set it up. It asked all the right questions about the network, and then set up to partition the disk. 9 partitions! What a way to improve your chances of filling one up. Tried the (bare-bones) partition editor to create a single root file system, which appeared to work, but for some reason I ended up with an unbootable system.

More notwork pain

Posted By Greg Lehey

More hung network switches today, this time with the added fun of a hung NFS connection on cvr2, which meant that I couldn't access it from outside: the ssh hung, and in the end it seemed easier to reboot. So what's causing the problems? One thing I didn't consider yesterday was the switch in my office. Played around with that, mainly to verify the model, and sure enough, I lost some network connectivity. Loose connection? That might explain why the problems occurred when I was in the office, and why it affected multiple systems. It doesn't explain why the problem went away after power cycling the other switches.

Another JSON Schema Gripe

Posted By Tim Bray

Recently I wrote of my disgruntlement with JSON Schema. Since then Ive learned that its authors plan more work, and that there are several other efforts to build a schema facility for JSON. This note is just a complaint about a particular use-case, with the hope that it might inform these efforts. Heres the problem; the language Im building includes a big object whose fields are also objects, and each of these child objects has a Type field, whose value is, in effect, an enum; a constrained set of string values. The rest of the fields in each child object depend on the Type value.

... with worn-out tools

Posted By Greg Lehey

Rudyard Kipling's If is a poem that has always impressed me. Now that I'm getting older, one of the line pairs that particularly impress me is: Or watch the things you gave your life to, broken, And stoop and build em up with worn-out tools: Somehow I'm reminded of that while trying to debug MythTV. Decades ago I wrote documentation about how to use gdb to debug normal programs and kernel problems. They came across very well. But they have atrophied.

Remembering svn chcekout

Posted By Greg Lehey

There are a number of open PRs on calendar(1) in the FreeBSD bug database, and also in my inbox. Time to finally do something about them before the first one turns 5 years old. Checked the how to repeat for PR 168785. I couldn't repeat it. Fixed? Check the log for /usr/src/usr.bin/calendar/calendar.c. This file is not under version control. Huh? Further investigation showed that once again the svn metadata were corrupt. This is happening far too often, though this time it could be due to the crash I had yesterday. How do I check out a working copy? It's in the Committer's Guide, which for some reason is difficult to find on the FreeBSD web site.

Local Network Problems

Posted By Greg Lehey

I was hardly out of bed and into the office this morning when Yvonne came and asked me if we had network problems. No, I didn't, but it seemed that she did: no communication from lagoon to eureka, on the other side of the house. What's the cause? No obvious problems on either lagoon or eureka. Switch? For some reason, switches seem to hang relatively frequently. Power cycled it, and it worked again. While wondering whether it was worth replacing the switch, discovered I couldn't communicate with teevee. But that's on another switch. My house wiring has a total of four switches: Main switch, in the pantry: 8 port 1000 Mb/s HP ProCurve 1800-8G, connecting to each of the rooms in ...

More MythTV debugging

Posted By Greg Lehey

So what's the cause of the problems I've been seeing with MythTV? I had assumed that it was related to the spurious DiSEqCDevTree warning, but after Tuesday's debug session that seems to be a red herring. So what would be an appropriate way to catch it? There are long delays before it comes back pretending there hasn't been a failure. Doesn't ktrace have an option to look at the times? No. It's in kdump, and there are two of them: elapsed time (-E) and relative time (-R). Chose the latter. After running the card detect function, I had a dump file about 180 MB in size!

Power fail recovery

Posted By Greg Lehey

I'm still running UFS with conventional soft updates. That seems to be a good choice for a system with reliable power: the system itself almost never crashes, and recovery, though slow, is infrequent. But since my RCD problems started, I have had to run fsck far more often than expected. I've adapted: even if the power fails in the middle of the night, reboot immediately so that the system will be up and running by the time I wake up. And my photo file system, nearly 4 TB in size, doesn't get mounted automatically. Thus it was today, but things still didn't work out.

One of my morning activities is to check mail and spam. Gmail does quite a good job of detecting spambetter than I've been able to do myselfbut it's not perfect, and in particular messages to the FreeBSD mailing lists frequently get classified as spam. Today I had one, sent to the freebsd-current mailing list by Greg Quinlan. Why? Why is this message in Spam?

NBN installation, for real

Posted By Greg Lehey

Over to Chris Rogers today to see how the National Broadband Network installation went. In fact, I didn't need to: they quickly established that he had adequate signal (-91 dB, comfortably above the -97 dB cutoff limit). But I wanted to talk to the installers about other similar cases. That proved to be useful. The installers were Mike and Jordan, who had been here last December to replace the hardware. Got a few new pointers: The term for the link, or maybe the antenna on the tower, is PCIno idea what that stands for.

Firefox: can't display plain text

Posted By Greg Lehey

Playing around with some old web pages today, I discovered: What? Since when do you need a helper application for plain text? firefox is a behemoth process over 2 GB in size, and it wants help displaying text, and that from another program at least as big as itself? It didn't even give me the option to display it directly.   PID USERNAME      THR PRI NICE   SIZE    RES STATE   C   TIME    WCPU COMMAND 47180 grog           61  20    0  2111M  1564M uwait   3  86:18   4.79% firefox Further investigation, with the help of a number of people on IRC, showed a number of strangenesses.

Phone call from Chris Rogers, who had got my number from Carolyn Everett. He's planning to have National Broadband Network fixed wireless installed tomorrow, and he's on the edge of the coverage maps between Dereel and Corindhap. He was concerned that he might be told he had no coverage, and asked me to come along in case there were any issues. ACM only downloads articles once.

Finally! Debug MythTV

Posted By Greg Lehey

I've spent most of the week fighting the Ports Collection trying to build a debug version of MythTV. I had the idea of installing the dependencies by first the package and then removing it again, but it didn't work. There were still large ports missing (can you spell Qt?) , and I ended up having to install the packages individually. And at least one port wouldn't build. This is all too fragile. But finally I got it built, and was able to run mythtv-setup with a debugger. All I needed was time to go through the sources, and today wasn't the day for that.

More MythTV fun

Posted By Greg Lehey

On somewhat half-heartedly with my MythTV build today. There must be a way to install all the dependencies as packages, rather than building them. But I didn't find an easy way. One Perl module included no less than 96 other dependencies, and that was the easy part. In the end I simply installed the MythTV package and then removed it again. And forgot to continue. ACM only downloads articles once.

Augeas: Updating of config files without ruining comments and formatting.

Posted By Tom Limoncelli

Wouldn't it be nice if you could write a program that could reach into an Apache config file (or an AptConf file, or an /etc/aliases file, Postfix master.cf, sshd/ssh config, sudoers, Xen conf, yum or other) make a change, and not ruin the comments and other formatting that exists? That's what Augeas permits you to do. If a config file's format as been defined in the Augeas "lens" language, you can then use Augeas to parse the file, pull out the data you want, plus you can add, change or delete elements too. When Augeas saves the file it retains all comments and formatting.

On with my mythbuntu experiments today. Back to remembering how to install NFS and ssh on Linux. Surprise, surprise! They were already there. All I needed was to mount /eureka/home and copy my ssh stuff. Then I was able to move the machine to the lounge room, connect the tuner and run mythtv-setup. Somehow things didn't work right.

Google: don't be evil!

Posted By Greg Lehey

The mythbuntu documentation isn't their own; it's on docs.google.com. It's conveniently set up to break X conventions. I can't copy text! I can mark it, but it doesn't get copied. When I right-click on the selection, I get: What braindeath is that? Microsoft, of course. And it doesn't work! Presumably Google is relying on their assumptions about the underlying window manager functionality. And for some reason it captures Ctrl-W too, so I can't close the window with the mouse. One more annoyance with Google.

Mythbuntu revisited

Posted By Greg Lehey

Why is MythTV pretending that my DVB-T tuner is a satellite tuner? One way to find out is to risk all kinds of physical and mental pain. Another would be to try a standard, out-of-the-box installation such as Mythbuntu (now mythbuntu, it seems) or KnoppMyth. My previous experiences with them were painful, too, but who knows what they're like now? Oh. No KnoppMyth any more. Now it's LinHES, an abbreviation that is intuitively recognizable. Which do I try? Last time round I settled on Mythbuntu, so that's what I tried first. First impressions: it looks a lot smoother. And the installation instructions point to this page about installing from a USB stick.

More free bandwidth!

Posted By Greg Lehey

Mail from Aussie Broadband today. Because I'm a loyal customer (how do you define that?) , they're giving me more traffic for the same price, 500 GB instead of 300 GB. That won't cost them anything: I'm not using my current allowance. I'm paying $60 a month, so this represents a price of $0.12 per GB. How things have changed since I got my first Internet connection in March 1992! Then I was paying 0.45 DM ($0.356 at today's exchange rate) per kilobyte! That corresponds to $356,000 per GB. So since then the data cost has gone down by 99.99996623%. So: how much traffic do I get for the next step down?

ENIAC circuitry

Posted By Greg Lehey

Yesterday Diomidis Spinellis published a blog entry relating to a book he has been reading, ENIAC in Action. In particular, he had tracked down one of the valves used in the circuitry, a 7AK7 pentode. Somehow that designation looks Just Plain Wrong. One of the most common ways of naming valves of those days was, as here, a number, letters and number. The first number was the heater voltage, the letters were used for differentiation from other similar valves, and the second number was the number of external connections. So this valve should have a heater voltage of 7 V and also have 7 connections (heater, cathode, 3 grids and anode; the heater has two connections).

10 git aliases I can't believe you don't have already

It makes me sad to see people type more than they have to. With these aliases, you reduce the 4 most common commands to 2 letter abbreviations: git config --global alias.co checkout git config --global alias.br branch git config --global alias.ci commit git config --global alias.st status NOTE: This updates your ~/.gitconfig file and adds aliasses "co", "br", "ci", and "st". If you collaborate with others, git pull makes a messy log. Instead, always type git pull --rebase --ff-only. This will make the merge history a lot more linear when possible, otherwise it falls back to the normal pull behavior.

And then awaiting collection! How can that be? The wonders of reverse chronological listing! But where was my email?

I am Satoshi Nakamoto, inventor of Bitcoin

Posted By Tom Limoncelli

There is a long and fraught history in Bitcoin of claims and counterclaims about who Satoshi is. I might as well confess that he is me. I come forward at this time because Craig Wright claims to be Satoshi and I can't stand such intentional scammery. If you read any of my pre-Bitcoin books, you'll see there are many pages where the first letter of each line reads "I am Satoshi Nakamoto" and "Someday I will invent Bitcoin". If you can't find the page that contains this, buy more copies of the books. You just haven't found the right one. Please use this link, since it includes my Amazon Associates code.

NBN Satellite: Salvation!

Posted By Greg Lehey

Julie Donaghy posted a reference to this article on Facebook today: The National Broadband Networks new Sky Muster satellite is now operational. So? It seems that there are enough people waiting for it, not understanding the issues. The alternative would be to put a fixed wireless antenna on a tower. That would cost money, of course, but satellite connections are more expensive, so it could make itself paid. Time for an explanation page. ACM only downloads articles once.
