Learning DxO PhotoLab
Spent a bit more time today trying to understand DxO PhotoLab. The first thing of interest is that each version of DxO wants its own Modules directory. What about a symlink? Played around with that on euroa. I didn't get it to work. The first time round, after replacing the directory with a pointer, it just hung when I started it. Maybe building a database? There's a file CAFList1010.db in the main directory, and from previous pain I know that it relates to the correction modules. But after an hour, it still hadn't done anything. OK, stop DxO PhotoLab, replace the local directories, and try again.
Learning about DxO PhotoLab
Yesterday I took a first look at DxO PhotoLab, but didn't find the tutorial videos. Off to look for them today. The web page doesn't inspire confidence: currently the menu at the top is non-functional, and when I finally found, at the bottom, a tab Learn: How to get started with DxO PhotoLab , which led me to a page with lots of tutorials about DxO Optics Pro , including old versions, and also completely irrelevant tutorials about their DxO ONE toy camera, but not a single tutorial about DxO PhotoLab. Maybe they'll come, but I'm left wondering whether DxO realize how bad an impression this makes.
DxO: Changing of the guard
DxO Optics Pro is dead, long live DxO PhotoLab. What's the difference? It's no longer Pro (a word that has long been meaningless), and it probably describes the current functionality better. Once it was just there for optical corrections, but in the 6½ years since I started using it, it has continually gained in functionality, much of which is not optical in nature. And from the somewhat garbled information I have on it, that trend seems to be continuing. So maybe the name makes sense. Downloaded the software and tried it out. Yes, a very familiar looking interface. But what's that green hook over each photo preview?

Induction cooking caveats
Changing the fat in the friteuse is always an issue. The fat is solid, but you can't heat it with the element because it needs to be immersed in fat. So in the past I've melted the fat separately in another pot and then put it into the friteuse. But now I have an induction cooker, and the pan of the friteuse is ferromagnetic, so I can do it directly. And it works. But it's still not without its problems. While heating it, I saw a spot in the pan glow red hot. No chance for a photo, of course, but it left its mark: Yet another reason to use thicker metal for cooking.
Working at Amazon
Sometimes when were trying to hire a senior employee, I get asked to do a sell call , tell them what its like to work here. Since Im coming up on three years and havent quit, I guess the supposition is that Ill be positive. Since these candidates are outsiders and some of them dont come to work for us, nothing I can say can be a secret. So why dont I tell everyone? Before I dive in any further, everything here relates to AWS, not Amazon as a whole. It might be true of the retail side too, but I dont know because I dont work there.
Stacking photos again
Finally I have yesterday's stacked photos converted to JPEG. Time to stack them. Once again DxO Optics Pro had produced output images of marginally different sizes, so align_image_stack refused to touch them. I've run into this problem in the past, and I should be able to find a way round it, either with different settings for DxO, or by manually trimming the images. On the other hand, align_image_stack has absolutely no support for deghosting, so presumably it would make a real mess of the moving flowers. So instead I used FOCUS Projects Professional, a program that I haven't used much. The results are really quite stunning.
My Qt World Summit keynote video is now online
The Qt World Summit videos were just posted, including my talk which was a condensed (40-minute) version of my CppCon 2017 metaclasses talk with some small tweaks for a Qt-specific audience. Here it is below:

Police reports in time of Internet
OK, still no refund from Craig Weber, about whom I only know phone numbers ((02) 9638 5221 and 0412 25 00 00), eBay user ID (klearview_au) and email address ([email protected]). Time for the police. Or is it? Checked the web site and discovered that it's not possible to report crimes online. Call the police station. So at 13:10 I called up the police in Ballarat on (03) 53366000, was presented with a long list of topics organized from their point of view, so finally chose uniform , something that is completely irrelevant to me. They weren't very helpful. After a while, they suggested an acorn.
Interview with InfoQ: C++17, and beyond?

Mobile phone GPS: inadequate
Somehow the accuracy of the GPS receiver in my Samsung GT-I9100T mobile phone leaves a lot to be desired. Lately I've been taking it while walking the dogs, but the logs suggest that I haven't left the property. Today I took it with me while taking photos of the mobile phone tower, with the car GPS navigator as a backup. It's easier to get the logs off the phone, so I did that. But the location I got was over 500 m away! That's clearly a different problem: It was further south, where I didn't go at all. The car GPS navigator worked fine, but of course showed the location of the car, not the location of the camera.
Another radiation tower!
The Dereel Facebook group is active again. There's more construction work going on round the National Broadband Network radiation tower on the corner of Rokewood Junction Road and Ballarat-Colac Road: Had a talk with the people erecting it. As expected, it's for Telstra mobile phones. Finally! It should be finished less than 5 years after Denis Napthine promised. They should have the tower up by the end of next week or so. It's not clear how long Telstra will take to activate it, but the foreman tells me that they installed the other end of the microwave link (on the Buninyong tower) at the beginning of the year.
Londoners! Ill be speaking at Waterstones Gower Street with Ada Palmer on Nov 8
By a very happy coincidence, Ada Palmer and I are both passing through London on November 8 and we’re doing a joint event at the Waterstones in Gower Street, starting at 6:30! The tickets (which include wine) are £6/£4 for students; you can book them here.

The future of cars
Margaret Swan has a new carwell, a different, newer one, a Subaru Forester with all bells and whistles. She's having difficulty with some of the bells (or was that whistles?) , so I came over today and took a look. There are two main issues of confusion: first, how do you start the car? For every car I have ever driven, there's an ignition key, usually coupled with a starter. Not on this car. Yes, there's a key, if you can reinterpret the information in the 300 page manual, which tells you to press in the wrong place, but you don't need it, and it doesn't help start the car.
Network foot-shooting
Part of repartitioning my (IPv4) network is to reset the net masks. Previously they were full /24 spaces (netmask 0xffffff00), and now they need to be set to /25 (netmask 0xffffff80). On my external machine the interface configuration looked like this: xn0: flags=8843 metric 0 mtu 1500 options=503 ether 00:16:3e:06:34:53 inet6 fe80::216:3eff:fe06:3453%xn0 prefixlen 64 scopeid 0x2 inet 208.86.226.86 netmask 0xfffffffc broadcast 208.86.226.87 inet 192.109.197.81 netmask 0xffffff00 broadcast 192.109.197.127 nd6 options=29 media: Ethernet manual status: active OK, that's simple enough: === root@www (/dev/pts/0) ~ 6 -> ifconfig xn0 inet 192.109.197.81 netmask 0xffffff80 No response.
Talking Walkaway on the CNet book-club podcast
CNet has started a new book-club podcast, and they honored me by picking my novel Walkaway as their second-ever title. We had a long and far-ranging discussion last week about the book and the themes it raises: disasters, economics, technological immortality, community, trolling, bohemianism, and much more (MP3). Since a big part of “Walkaway” concerns... more
Garden sprinkler failure
It's getting warmer, and I've been keeping an eye on the soil moisture. Today I discovered that the sprinkler system wasn't working At All. Further investigation revealed an interesting reason: the sprinkler controller was off the net. For quite some time I haven't really been doing much with my Class C network block, but it's probably about time. All my systems at home are in the top half, so I can do things with the other half, including migrating the web site to that area. That seemed straightforward enough until I discovered that our sprinkler system wasn't working any more: a network configuration error.
Lens image stabilization?
When I bought my Leica DG Vario-Elmarit 12-60 mm f/2.8-4, one of the first things I did was to test the image stabilization. One of the drawbacks of using a non-Olympus lens was that I could have lens stabilization or body stabilization, but not both. And it turned out that the body stabilization was much better than the lens stabilization, so that feature wasn't worth much. Now I have the M.Zuiko Digital ED 12-100 mm f/4.0 IS PRO, my first stabilized Olympus lens, so of course I wanted to see how much difference that makes.
My adult novels are being reissued with covers to match Walkaway!
When I first saw Will Stahle‘s cover art for my novel Walkaway, I was pleased beyond all reason (and not least because I am an unabashed Stahle fanboy, as he is behind some of the greatest covers of our era, from Yiddish Policeman’s Union to Autonomous to A Darker Shade of Magic to All the... more
11 is the new 7: iOS designers, what is it with the motion fetish? Please stop making us motion sick

Dealing with technology
My trip to Misery Creek Road involved a fair amount of technology: camera, mount and GPS recorders. The mount worked well: I think that tripod is one of the best purchases I have made recently. But other things didn't work as well. The photos of the Chamaescilla came out so dark that I thought there was no recovery possible. DxO Optics Pro proved equal to the task, but why the bad exposure in the first place?
Orchid hunt
On Tuesday I found a new orchid in Misery Creek Road: It's a Caladenia major, and it's out of focus (only visible on enlarging the image). Today the weather was calm, just the conditions for focus stacking, so off to Misery Creek Road again to look for one.
IP-IP tunnel experiments
Somehow I still can't get my head around IP-IP tunnels. Last time I set one up, I only had one end to contend with. Now I have two, and NAT in between to boot. Made a clone of a virtual machine to play with, and followed these instructions. They didn't quite work for me, but I'm wondering if my translation of the IP addresses wasn't to blame. One of the more bizarre messages was: Oct 13 17:41:37 stable-11 kernel: gre0: loop detected I suspect that has to do with use of the same IP range on different interfaces.
Still more lagoon mail problems
Yvonne came to me today with a bounce message I had never seen before: I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. The mail system <[email protected]>: cannot update mailbox /var/mail/yvonne for user yvonne. file is a symbolic link Well, yes, it's right. /var/mail/yvonne is a symlink. And so it has been for longer than I can remember, maybe 15 years. Is this some new thing in postfix?
Live Metal is Better
Recently I went out for a live metal triple-bill, with Endon and SUMAC opening for Boris, whom Ive covered here before (with groovy pix). More pix today, with words on the history and meaning of metal, and how to photograph it. Endon, the openers, are described as catastrophic noise metal and yeah, they were pretty catastrophic. A little too abstract for me, but sincere and really trying to bring it. Didnt get any pix. Heres my problem: I wholeheartedly love this music, in particular live, and yet I have to acknowledge that its sort of, well, ridiculous. The volume is much louder than can be sanely necessary.
Compressing web pages?
Discussing what a reasonable web page size is today on IRC. Jamie Fraser thought that 2 MB is too much. I wondered how big my diary pages are. Checked with last month's diary: === grog@eureka (/dev/pts/27) /var/tmp 78 -> fetch http://www.lemis.com/grog/diary-sep2017.php diary-sep2017.php 738 kB 275 kBps 00m02s Is that too big? That's even without the images. People suggested compression. Here a part of the discussion for my future reference: <fwaggle> gr00gle: doesn't look like your webserver is gzipping your html would would probably slash that <gr00gle> Do all web clients understand that?
Fixing lagoon mail
Got round to looking at the mail system on lagoon today. Put in the configuration files from the old system, restarted postfix, and found: postfix: Postfix is running with backwards-compatible default settings postfix: See http://www.postfix.org/COMPATIBILITY_README.html for details postfix: To disable backwards compatibility use "postconf compatibility_level=2" and "postfix reload" postfix/postfix-script: refreshing the Postfix mail system Oct 12 09:36:29 lagoon postfix/qmgr[55707]: 3838B2730FD: from=<>, size=2687, nrcpt=1 (queue active) Oct 12 09:36:59 lagoon postfix/smtp[55776]: connect to dereel.lemis.com[192.109.197.135]:25: Operation timed out dereel.lemis.com? That's been out of commission for years, since I put everything into eureka.
lagoon: problems gradually arrive
Last week's upgrade to lagoon went remarkably smoothly. The only issue was with mutt, which really had nothing to do with the upgrade. But today Yvonne wanted to send an important mail message, They wanted her to print out a file, fill it out by hand, scan it in, and send it by email. She came to me and said don't bother about the email I sent you. Chris will print it for me . Huh? Why do we need Chris to print files for us? Went to show her how to download a PDF file and print it out. === yvonne@lagoon (/dev/pts/2) ~/Downloads 51 -> lpr MEA-Application-Form.pdf lpr: Error - scheduler not responding.
Debugging mutt
Why did Yvonne's mutt stop working after I upgraded her system? I discovered that it was due to mutt_dotlock failing, and that unlike on previous occasions, it was not due to NFS. But it worked for me, and it didn't work for Yvonne. Why not? Finally found time to have another look. Things weren't made any easier by the fact that mutt_dotlock runs setgid, so ktrace doesn't trace it. How about the good old debugger? How do you create a version of the program with symbols? A couple of months ago I found how to do it for FreeBSD software, but mutt is a port.
Playing with Marble
One of the GPS-related software components that I wanted to look at was marble, and did so today. It's a KDE application, which means that if I don't have a KDE environment, I don't get any help. Still, this stuff is straightforward, right? No, it's KDE. Climbing directory trees is bad enough with firefox, but KDE goes one step further by renaming the directories: Home isn't /home, it's (in my case) /home/grog/. How I hate software that tries to hide the system from you! Tried it out anyway. There's an Open tab, which I used to painstakingly walk my way to my GPS logs.
Bloody eBay, day 3
OK, it's been nearly a month since I ordered a disk on eBay, and I still have neither item nor refund. And eBay, in its infinite wisdom, has decided that A refund won't be issued for this case . I've already complained vociferously about this decision. But that's just eBay. I still have a case against Craig Weber (eBay seller klearview_au). Call up Consumer Affairs Victoria, and while waiting in the inevitable hold pattern, was referred to the web site. For once, that might make sense, and so I took a look. Buying from a private seller online fits the bill. And in my case, they recommended that I contact the police: If consumers used an instant cash transfer system (such as Western Union or MoneyGram) or deposited money ...
Processing GPS information
Yesterday's journey left me with no fewer than 8 GPS logs, none of them covering the entire journey. I left the phone (talipon) charging until we got to Halls Gap, and the car navigator (the other seven) stopped logging every time I stopped the car, so I had some gaps. In any case, I didn't know how to process the logs. There must be a converter... After a bit of searching, found GPSBabel ( convert, upload, download data from GPS and Map programs ). Just what I need, and there's a FreeBSD port for it, so I installed it. === grog@teevee (/dev/pts/4) ~ 24 -> man gpsbabel No manual entry for gpsbabel Clearly a modern program.
eBay does it again!
Clearly it was a mistake on eBay's part to close my case yesterday without a refund. Maybe the first one was done by computer, but clearly an appeal should get the attention of a human. Maybe it did, but I was still astounded by their final (final) decision: Again no reason. How can they get away with this? Time to make some noise. Every time (far too many of them) that I have trouble with eBay, I try to find some valid, honest reason.
Vendor jerks at tech conferences
(I've intentionally delayed posting this so that it wasn't clear which conference I'm talking about.) So... I'm at a conference. I take a break from the talks to walk around the vendor show. While most of the booths are selling products I'm not interested in, I suddenly find myself in front of VENDOR-A (name changed to protect them). VENDOR-A makes a product that has both open source and commercial editions, a common business model. Since the company I work for is a happy user of their open source version, I decide to ask about the commercial version. Maybe there's some benefit to be had.
GPS: How to ruin an outing
Off to Halls Gap today for the annual Grampians Wildflower Show, as mentioned yesterday. I had spent some time planning the route: unlike in other countries, small back roads are usually faster than the main highways. They're more direct, usually in acceptable condition, and the main Western Highway is usually congested. In the days before GPS I worked out a number of ways from Skipton to Ararat, and the navigator took me somewhere round there. So yesterday I stored the route in my GPS navigatornot an easy business, since navigators go by addresses, not generally landmarks. So I had had to manually type in the coordinates, which it didn't like much either: not reachable by road.
eBay: No item, no refund, no explanation
As if I didn't have enough to do over the weekend, eBay decided about the seller who took my money and didn't deliver. They decided that that was correct, and that I should not get a refund: A final decision! With the option to appeal. That sounds right for eBay. But what nonsense! How can they refuse to admit a refund? And why don't they attempt to justify their decision? Of course I appealed.
Macro Trends
In The bubble without any fizz, The Economist addresses the fact that financial-asset prices (stocks, bonds, and the like) keep drifting up and up in a world where inflation doesnt; are we in a mega-bubble? Whats really going on? Looks obvious to me, but then Im a left-winger. I think its all a straightforward consequence of economic efficiency and class warfare. Inflation? It stays low because our globalized economy is hyperefficient at making the things we want, extracting the fuels we burn, and growing the food we eat. And also flexible enough that it can scale up and down to meet demand without apparently kicking off waves of inflation or bankruptcy.
Grampians wildflower show?
This weekend is the Grampians Wildflower Show, whose web site includes a prominent 404 ( Spring into the Grampians ) and few details. The heading EVENT DETAILS promises more information closer to the date, and there's no address for the main venue; you have to find that elsewhere (it's 117 Grampians Road, Halls Gap). While I was there, I looked for a few other locations of interest in another link that I found, with nice pictures but again hazy on location. Boroka Lookout looks stunning, but a 90m walk each way? That's too long for us, and it wouldn't fit in the time plan.
IP tunneling
ZDF seems to have a different algorithm from other German broadcasters for determining whether I'm in Germany or not, and for some reason they have decided that I am not. Presumably this is based on analysing different IP addresses. OK, my Class C is routed internationally, though it stops somewhere in North Carolina. I can easily route it on to here, but various considerations make it a bad idea in general. What I really need is the way to tunnel a specific IP address from there to here. OK, that's what an IP-IP tunnel is, right? I've used one of them before, and have exact instructions.
How do you like AusPost service?
Automatic phone call from Australia Post today to ask me how I liked yesterday's interaction with their customer service team. Answered appropriately, and was offered the option to be connected with customer service for a follow-up. OK, since they asked, selected the option and was connected to Orrin. Asked him to forward a problem report to the IT people that their server 116.240.201.166 didn't have reverse lookup. OK, noted, will inform people. A little too fast ( let's get rid of this crank ). Asked him to repeat the number, and of course he couldn't. Asked to be connected to a supervisor, and he went through the motions, came back and started asking questions about my item.
More lagoon problems
It turned out that yesterday's fix to Yvonne's read-only mailbox issue didn't work. Her index page looks different, and the % sign indicating read-only status was in a different position. Back to my diary to find out what I did last time. On 13 June 2010 the issue was a missing rpc.lockd process. But that wasn't the case today. On another occasion I rebooted, and that worked round the problem. That sounds so Microsoft. So I went looking. Permissions? Yes, that seems reasonable, but they were all correct. Make a local copy? Worked. So an NFS problem. ktrace showed the mailbox being opened twice, each time O_RDONLY.
Latest compromise attempt

Upgrading lagoon
Yvonne was shipping in town today, a good time to upgrade lagoon, her computer. It went surprisingly well: On eureso, the development VM, which has eureka's file systems mounted, tar --one-file-system -cf /src/r / The name is deliberately short to make it easier to enter on the console. /src is a symlink from /home/src. Boot the new machine from DVD.
Upgrading lagoon
I now have a new system disk for lagoon, Yvonne's computer. Time to upgrade the system, which also involves moving it to a smaller, quieter box, my old ThinkCentre that was once called despair. First problem: despair does not have a DVI output. Will I even be able to start X on it in native resolution? But that's in the future. For the time being, how do I migrate? Downloaded the latest FreeBSD installation disk and started it. Things have changed at some point, and I was rather surprised to see the install DVD want to fsck itself. Chose my standard disk layout: two alternative root file systems, 40 GB each, 20 GB of swap, and the rest of the 2 TB 1.8 TB as /home.
An Embarrassing Failure
My colleague Georgios Gousios and I are studying the impact of software engineering research in practice. As part of our research, we identified award-winning and highly-cited papers, and asked their authors to complete an online survey. Each survey was personalized with the author's name and the paper's title and publication venue. After completing a trial and a pilot run, I decided to contact the large number of remaining authors. This is when things started going horribly wrong.
More multimedia download stuff
Continued investigating how to get programmes from SRF today. There's this script, which complained about non-implemented functionality. It starts: #!/bin/sh Who uses /bin/sh any more? Linux people just link it to /bin/bash, so I guessed that it required bash functionality. Changing the first line to point to bash fixed it. Then I ran it, and got no output, neither on the screen nor on the disk. Time for some script reading. It seems that it's really just a wrapper for rtmpdump, which proves to be related to mplayer.
A Decade of Dynamo: Powering the next wave of high-performance, internet-scale applications
Today marks the 10 year anniversary of Amazon's Dynamo whitepaper, a milestone that made me reflect on how much innovation has occurred in the area of databases over the last decade and a good reminder on why taking a customer obsessed approach to solving hard problems can have lasting impact beyond your original expectations. It all started in 2004 when Amazon was running Oracle's enterprise edition with clustering and replication. We had an advanced team of database administrators and access to top experts within Oracle. We were pushing the limits of what was a leading commercial database at the time and were unable to sustain the availability, scalability and performance needs that our growing Amazon business demanded.

More multimedia download insights
I'm still trying to find out how to download videos from SRF. MediathekView can download some of them, but only some of them. Yesterday I had tried to view one that doesn't show up in the MediathekView list, but had been told that, due to content restrictions, it was only accessible between 22:00 and 6:00, implicitly CET. That's OK here, especially since we moved to DST: it corresponds to 7:00 to 15:00 here. And then I was told it was only accessible in Switzerland. It did that with some other programmes too, including stuff that was included as free in MediathekView.
