I've been doing a little bit of dynamically typed programming in Haskell, to improve Propellor's Info type. The result is kind of interesting in a scary way. Info started out as a big record type, containing all the different sorts of metadata that Propellor needed to keep track of. Host IP addresses, DNS entries, ssh public keys, docker image configuration parameters... This got quite out of hand. Info needed to have its hands in everything, even types that should have been private to their module. To fix that, recent versions of Propellor let a single Info contain many different types of values. Look at it one way and it contains DNS entries; look at it another way and it contains ssh public keys, etc. As an migr from lands where you can never know what type of value is in a $foo until you look, this was a scary prospect at first, but I found it's possible to have the benefits of dynamic types and the safety of static types too. The key to doing it is Data.Dynamic. Thanks to Joachim Breitner for suggesting I could use it here. What I arrived at is this type (slightly simplified):

newtype Info = Info [Dynamic]
    deriving (Monoid)

So Info is a monoid, and it holds of a bunch of dynamic values, which could each be of any type at all. Eep! So far, this is utterly scary to me. To tame it, the Info constructor is not exported, and so the only way to create an Info is to start with mempty and use this function:

addInfo :: (IsInfo v, Monoid v) => Info -> v -> Info
addInfo (Info l) v = Info (toDyn v : l)

The important part of that is that only allows adding values that are in the IsInfo type class. That prevents the foot shooting associated with dynamic types, by only allowing use of types that make sense as Info. Otherwise arbitrary Strings etc could be passed to addInfo by accident, and all get concated together, and that would be a total dynamic programming mess. Anything you can add into an Info, you can get back out:

getInfo :: (IsInfo v, Monoid v) => Info -> v
getInfo (Info l) = mconcat (mapMaybe fromDynamic (reverse l))

Only monoids can be stored in Info, so if you ask for a type that an Info doesn't contain, you'll get back mempty. Crucially, IsInfo is an open type class. Any module in Propellor can make a new data type and make it an instance of IsInfo, and then that new data type can be stored in the Info of a Property, and any Host that uses the Property will have that added to its Info, available for later introspection.

For example, this weekend I'm extending Propellor to have controllers: Hosts that are responsible for running Propellor on some other hosts. Useful if you want to run propellor once and have it update the configuration of an entire network of hosts. There can be whole chains of controllers controlling other controllers etc. The problem is, what if host foo has the property controllerFor bar and host bar has the property controllerFor foo? I want to avoid a loop of foo running Propellor on bar, running Propellor on foo, ... To detect such loops, each Host's Info should contain a list of the Hosts it's controlling. Which is not hard to accomplish:

newtype Controlling = Controlled [Host]
    deriving (Typeable, Monoid)
isControlledBy :: Host -> Controlling -> Bool
h  isControlledBy  (Controlled hs) = any (== hostName h) (map hostName hs)
instance IsInfo Controlling where
    propigateInfo _ = True
mkControllingInfo :: Host -> Info
mkControllingInfo controlled = addInfo mempty (Controlled [controlled])
getControlledBy :: Host -> Controlling
getControlledBy = getInfo . hostInfo
isControllerLoop :: Host -> Host -> Bool
isControllerLoop controller controlled = go S.empty controlled
  where
    go checked h
          controller  isControlledBy  c = True
        -- avoid checking loops that have been checked before
          hostName h  S.member  checked = False
          otherwise = any (go (S.insert (hostName h) checked)) l
      where
        c@(Controlled l) = getControlledBy h

This is all internal to the module that needs it; the rest of propellor doesn't need to know that the Info is using used for this. And yet, the necessary information about Hosts is gathered as propellor runs.

So, that's a useful technique. I do wonder if I could somehow make addInfo combine together values in the list that have the same type; as it is the list can get long. And, to show Info, the best I could do was this:

 instance Show Info where
            show (Info l) = "Info " ++ show (map dynTypeRep l)

The resulting long list of the types of vales stored in a host's info is not a useful as it could be. Of course, getInfo can be used to get any particular type of value:

*Main> hostInfo kite
Info [InfoVal System,PrivInfo,PrivInfo,Controlling,DnsInfo,DnsInfo,DnsInfo,AliasesInfo, ...
*Main> getInfo (hostInfo kite) :: AliasesInfo
AliasesInfo (fromList ["downloads.kitenet.net","git.joeyh.name","imap.kitenet.net","nntp.olduse.net" ...

And finally, I keep trying to think of a better name than "Info".

I have worked with ARM based systems for longer than I care to admit to myself. From the Acorn Archimedes 305 in 1987 through to modern 64bit systems I have seen many many changes in the ARM community. One big change has been the rise of the inexpensive single board computer (SBC).

Arguably the Raspberry Pi (RPi) was responsible for starting this trend. Before RPi there were small development boards available, I was even involved in producing some of them, none of these really became a big thing and were principally vehicles for silicon vendors to showcase their SoC in an accessible way. When I say accessible I mean for silicon vendors who were previously used to charging many thousands of pounds for their development boards now only charging hundreds.

In my opinion the RPi was a complete disruption to the SBC market. In early 2012 a complete ARM computer system could now be purchased for $35 ( 25) which was substantially cheaper than the best contemporary competitor the Beaglebone $89 ( 60)

To be clear, the reason the RPi succeeded (millions sold, household name) was not on price alone but also the large amount of good supporting software and how easy it was made for teachers and makers to use.

There were several areas that the RPi managed to change perceived issues into opportunities for using what was already available or third parties to provide. There were also several issues raised about the original RPi:

no case
no integrated storage
not having an x86 processor
being a slow processor
limited peripheral support
no real time clock
not supplying keyboards, mice
not providing displays.

Some of these have been addressed since release as the foundation now sells cases, hardware revisions with much more powerful processors, pre-configured storage, cameras and displays. The important thing to note here though is the RPi has made the bare SBC a much more widely accepted product where all the non critical parts are considered "extras" and a lot is forgiven because of the price.

With that acceptance there have been many, many new SBC coming to market with better peripherals and increasingly competitive pricing. These are technically not clones as none of them use the Broadcom processor of the RPi but they often share many features and possibly even a compatible expansion header.

Banana pi in my case with a 2.5inch drive bay

The Banana Pi was one of these copycats which I acquired for a similar price as an RPi in 2014. The main processor of this system was a 1Ghz dual core Allwinner A20 processor (a considerable advance on the 700MHz single core of the original RPi) coupled to a gigabyte of memory. Additionally the board benefited from having SATA and gigabit Ethernet MAC which made for a much more versatile system. Various third parties filled in the missing peripherals including my own attempt at a case.

I acquired a cubietruck for the NetSurf project to use as a build node in their CI system this is again based on the A20 but with more memory and somewhat better peripheral support but at a substantial cost over the Banana Pi.

The most recent addition to this form factor is the introduction by Xunlong Software of the Orange Pi PC. This little board is the same footprint as the RPi2 B+ design but with differing connector placement. The processor is a quad core 1.6GHz Allwinner H3 with a gigabyte of memory and has has Ethernet and USB but no SATA.

The big news about this board though is the price, at $15 ( 10) it resets the price expectations just as the RPi did before it. I was initially sceptical of the quality of the product (or if it would arrive at all) but I have acquired five of these boards and every one of them came well packaged, boxed and in a static bag, just like the RPi does, and they all worked.

I created a case design based on my RPi slimline case so they would be protected when piled up with all the other boards. The use of a DC barrel jack instead of micro USB for power is better in that the connector is more robust and intended for higher current draws but does mean additional leads are needed. There are, however, two flies in the ointment, neither are showstoppers but make the board a little more difficult to use.

One is a simple necessity of a substantial heatsink on the H3 processor. Initially I used a small 20 x 20mm copper heatsink (around 800mm square surface area) but this was insufficient under full load. I did not want to have to use a fan so I milled some slots into copper round bar, then cut off sections and faced them on a lathe. The completed design had more than 2200 square mm surface area and cost around $2.5 ( 1.5) in material (and a couple of hours in the workshop but that was fun and I made something)

The second issue and arguably much more serious is that of software. Let me be honest, it is dreadful, I mean very bad indeed. The images provided from the Orange Pi website are some of the worst examples of "do something quick" I have experienced.

Fortunately a user on the forums named loboris decided to create scripts that generate a Debian (and Ubuntu and Fedora) distribution images that can be installed from SD card. He relies on a somewhat patched 3.4 kernel full of Allwinner vendor changes and the inevitable binary blobs for the Marli GPU but the result does work.

I have had a few units acting as distcc compiler slaves for two weeks now at 100% CPU loading and they are still running. The processor does not get overly warm with the heatsink installed and Debian behaves just fine. The main caveat being that it is definitely not going to work if you try and update the kernel through packaging.

The state of software support and Xunlong Software relying on a forum user to complete their product does tarnish an otherwise impressive and possibly market changing SBC.

Perhaps I expect too much for fifteen bucks? I guess when the cost of the case, heatsink, cables and memory storage card is similar to the rest of the computer there is simply no margin left for anything else.

In conclusion hopefully this brief overview has provided some insight into what is available in this market and that the Raspberry Pi is indeed not the only option.

I finish with an image is of my ARM build farm consisting of every SBC I mention here (including a couple of RPi)

A big update of all related packages (tex-common 6.04, texlive-bin 2015.20150524.37493-7, texlive-base/lang/extra package 2015.20151016-1) due to the move to support multi-arch. Of course, the regular updates of the TeX Live are included, too. With this change it should be possible to run a multi-arch system with only one TeX Live installed. Debian - TeX Live 2015

Thanks to the excellent support and testing of the Multi-arch guys, in particular Thorsten Glaser, Helmut Grohne, Johannes Schauer, and Wookey, I learned a lot about multi-arch, and I hope that the current setup is safe. All the packages but the various lib* packages are tagged as Multi-Arch: foreign, while the lib packages are tagged Multi-Arch: same. Anyway, if you find a bug concerning multi-arch, that is that some of the programs exhibit architecture information, please let us know via a bug report.

Usual regular update of the TeX Live packages. Now that Debian/unstable is back to full development speed thanks to the end of the bit gcc transition, probably this TeX Live update will be lost between the hundreds of others. Anyway a few interesting changes are still in there. Debian - TeX Live 2015

Most importantly the fix for unicode-math that was broken for a short time, and for the Japanese users it seems that the LaTeX3 packages have gained support for upTeX. Good to hear. Of course, these are not the only updates and newcomers, see the list below. Updated packages abc, acro, alegreya, animate, arabxetex, babel-bosnian, babel-french, babel-greek, babel-latin, babel-welsh, beamer-FUBerlin, bidi, bigfoot, blochsphere, bxjscls, chemformula, chemmacros, chet, classicthesis, crossrefware, csplain, ctable, ctanify, datetime2, datetime2-basque, detlev-cm, disser, doclicense, drm, dtxgen, dtxtut, dvips, ecclesiastic, eledmac, embrac, etex-pkg, etoc, factura, fbb, fithesis, font-change, fontname, glossaries, gothic, greek-fontenc, IEEEtran, l3build, l3experimental, l3kernel, l3packages, latexconfig, lettrine, luatexja, mathastext, mcf2graph, media9, metrix, mhequ, minted, moderntimeline, newtx, ocgx2, pagecolor, pdftex, pgf, pstricks, reledmac, resphilosophica, roboto, shdoc, siunitx, suftesi, tetex, tex4ht, texlive-scripts, tikz-bayesnet, translations, ucharcat, udesoftec, ulthese, unicode-math, ut-thesis, withargs, xint. New packages checklistings, cleanthesis, easyreview, fei, medstarbeamer, mfirstuc, nevelok, old-arrows, proofread, uassign, xebaposter. Enjoy.

For those who are starving for some updates while the big gcc5 transitions brings the rest of Debian/sid to a halt, here is some fresh meat, a new TeX Live checkout. Nothing spectacular new here, just the usual big bunch of updates of and several new packages. Maybe worthwhile mentioning is that luasseq has been reincorporated into the TeX Live packages. Thanks to the maintainer for his work till now! Debian - TeX Live 2015

From the long list of changes let me pick one update and one new package: pgf has been updated to 3.0.1, which is just a small change in number, but incorporates 1.5 years of fixes, and the list of fixes is long. And a very interesting newcomer is pdfpagediff by C. V. Rad hakr ish nan. It allows visual comparison of two pdf files by overlaying them in a transparent way, making even slight changes in the layout immediately visible. Of course, these are not the only updates and newcomers, see the list below. Updated packages academicons, addlines, algorithms, archaic, babel, babel-estonian, biber, biblatex-source-division, bidi, bxjscls, chronology, cjk-ko, conteq, csplain, csquotes, curve2e, datatool, doclicense, dvips, eledmac, enotez, esami, eso-pic, etex-pkg, etoolbox, exsheets, fandol, fithesis, fontawesome, fontspec, forest, glossaries, greek-inputenc, jslectureplanner, kotex-oblivoir, kotex-utf, l3build, l3experimental, l3kernel, l3packages, latex, leadsheets, ledmac, lshort-english, luamplib, luasseq, luatexko, maths-symbols, media9, memoir, metrix, mhchem, minitoc, moderncv, modiagram, morefloats, mptopdf, msu-thesis, nameauth, ndsu-thesis, newpx, newtx, newtxsf, newtxtt, notes, ocgx2, pageslts, pdfpages, pdftex, pgf, phonrule, plain, polyglossia, pstricks, ptex, pxchfon, reflectgraphics, rsfso, sectionbox, siunitx, skrapport, standalone, tcolorbox, tetex, tex4ht, texfot, texinfo, texlive-scripts, todonotes, translations, tudscr, ucbthesis, unicode-math, xcharter, xgreek.

TinyTiny-RSS has some nice failure modes. And upstream support forums aren't really helpfull so when you search for your current problem, chances are that there is one mention of it on the web, in the forum, and the only thing happening there is people making fun of the reporter. Anyway. This installation has seen lots of error messages from the updater in the last several months:

And, more recently, the android app stopped working with ERROR:JSON Parse failed.. Turns out both things are related. First thing I noticed was changing preferences in the web panel stopped working until you use the reset to Defaults option and then changed settings. Plugging wireshark in between showed what was going on (Note: API was displayed as enabled in Preferences/Preferences):

Solution for fixing the Android app (and the logspam on the way as well) seems to be to reset the preferences and then configure tt-rss again (In the webapp, not in the android thing!). Also silences tt-rss update_daemon as well, yay! One last thing: someone out there who wants to explain to me how to fix

After long time of waiting we finally released TeX Live 2015. Get some champagne, and ready to party!

Get it via downloading the net-installer, by obtaining a DVD, or downloading the iso. Besides the huge list up updates to packages and loads of bug fixes to all the programs, here are some notable news:

new LaTeX2e release which automatically includes fixltx2e
pdfTeX got improved jpeg support (exif and JFIF)
luaTeX got a new library newtokenlib
XeTeX got image handling fixes
MetaPost got a new numbersystem binary, and Japanese variants were added (upmpost and updvitomp)
MacTeX s Ghostscript packages got a facelift with better CJK support, other Unix-like distributions can do the same with my the newly included script cjk-gs-integrate (also one one my projects)
fmtutil got rewritten in perl, as reported here
architectures: *kfreebsd was removed,and some additional platforms available as custom binaries. The DVD does not contain all platforms (due to space reasons), but all of them can be installed via the net-installer.

Regular updates of the repository will start in due course. Thanks to all the contributors for the hard work. Let s have a party!

This weekend I had to downgrade my home desktop to stable thanks to a strange Xorg bug which I've been unable to identify among the current ones. Both testing and sid versions seem affected and all you can see after booting is this:

The system works fine otherwise and can be accessed via ssh, but restarting kdm doesn't help to fix it, it just changes the pattern. Anyway, as explaining a toddler he cannot watch his favourite youtube cartoons because suddenly the computer screen has become an abstract art work is not easy I quickly decided to downgrade.

Downgrading went fine, using APT pinning to fix stable and apt-get update/upgrade/dist-upgrade after that, but today I noticed libreoffice stopped working with this message:

Warning: failed to launch javaldx - java may not function correctly
/usr/lib/libreoffice/program/soffice.bin: error while loading shared libraries: libreglo.so: cannot open shared object file: No such file or directory

All I found related to that is a post on forums, which didn't help much (neither the original poster nor me). But just found the library was not missing, it was installed:

# locate libreglo.so
/usr/lib/ure/lib/libreglo.so

But that was not part of any ldconfig conf file, hence the fix was easy:

# echo '/usr/lib/ure/lib' > /etc/ld.so.conf.d/libreoffice-ure.conf
# ldconfig

And presto! libreoffice is working again :-)

I recently acquired a Lenovo Yoga 2 13. While, at the time, the Yoga 3 was available, I decided to go for Yoga 2 13. The Yoga 3 comes with the newer Core M Broadwell family, which, in my opinion, doesn't really bring any astounding benefits. The Yoga 2 13 comes in mulitple variants worldwide. Infact these hardware variations have different effets when run under Linux. My varaint of Yoga 2 13 is:

In the interim, to overcome this problem, we can force the device to run in degraded mode. I'm not sure if it is really the degraded mode, or the device was falsely advertised as a 6 GiB capable device. Time will tell, but for now, force it to run in 3 GiB mode, and so far, I haven't run into the above mentioned probems. To force 3 GiB speed, apply the following.

rrs@learner:~$ cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-4.0.4+ root=/dev/mapper/sdb_crypt ro cgroup_enable=memory swapaccount=1 rootflags=data=writeback libata.force=1:3 quiet
16:42

And then verify it... As you can see below, I've forced it for ata1 because I want my SSD drive to run at full-speed. I've done enough I/O, which earlier resulted in the kernel spitting the SATA errors. With this workaround, the kernel does not spit any error messages.

And the throughput you get out of your WD SATA SSHD drive, with capability set to 3.0 GiB is:

rrs@learner:/media/SSHD/tmp$ while true; do dd if=/dev/zero of=foo.img bs=1M count=20000; sync; rm -rf foo.img; sync; done

Hannes Reinecke has submitted patches for NCQ enhancements, for Linux 4.1, which I hope will resolve these problems. Another option is to disable NCQ for the drive, or else blacklist the make/model in driver/ata/libata-core.c

By the time I finished this blog entry draft, I had tests to conclude that this did not look like an NCQ problem. Because in degraded mode too, it runs with NCQ enabled (check above).

rrs@learner:~$ sudo fstrim -vv /media/SSHD
/media/SSHD: 268.2 GiB (287930949632 bytes) trimmed

rrs@learner:~$ sudo fstrim -vv /
[sudo] password for rrs:
/: 64 GiB (68650749952 bytes) trimmed
16:56

Another interesting feature of this drive is support for TRIM / DISCARD. This drive's FTL accepts the TRIM command. Ofcourse, you need to ensure that you have discard enabled in all the layers. In my case, SATA + Device Mapper (Crypt and LVM) + File System (ext4) Display

The overall display of this device is amazing. It is large enough to give you vibrant look. At 1920x1080 resolution, things look good. The display support was available out-of-the-box.

There were some suspend / resume hangs that occured with kernels < 4.x, during suspend / resume. The issue was root caused and fixed for Linux 4.0.

You may still notice the following kernel messages, though not problematic to me so far.

You may need to disable the Intel Management Engine Interface (mei.ko), incase you run into suspend/resume problems.

rrs@learner:/media/SSHD/tmp$ cat /etc/modprobe.d/intel-mei-blacklist.conf
blacklist mei
blacklist mei-me
17:01

You may also run into the following Kernel Oops during suspend/resume. Below, you see 2 interation of sleep because it first hibernates and then sleeps (s2both).

Network

In my case, the laptop came with the Realtek Wireless device (details above in lspci output). Note: The machine has no wired interface.

While the Intel Wifi devices shipped with this laptop have their own share of problems, this device (rtl8723be) works out of the box. But only for a while. There is no certain pattern on what triggers the bug, but once triggered, the network just freezes. Nothing is logged.

If your Yoga 2 13 came with the RTL chip, the following workaround may help avoid the network issues.

rrs@learner:/media/SSHD/tmp$ cat /etc/modprobe.d/rtl8723be.conf
options rtl8723be fwlps=0

MCE

Almost every boot, eventually, the kernel reports MCE errors. Not something I understand well, but so far, it hasn't caused any visible issues. And from what I have googled so far, nobody seems to have fixed it anywhere

So, with fingers crossed, lets just hope this never translates into a real problem.

What the kernel reports of the CPU's capabilities.

Review: Some Remarks, by Neal Stephenson

Publisher:	William Morrow
Copyright:	June 2013
ISBN:	0-06-202444-2
Format:	Trade paperback
Pages:	336

This is going to be another weird review, since I read this essay collection about three months ago, and I borrowed it from a friend. So this is both from fading memory and without a handy reference other than Internet searches. Apologies in advance for any important details that I miss. The advantage is that you'll see what parts of this collection stuck in my memory. Some Remarks is, as you might guess from the title, a rather random collection of material. There's one long essay that for me was the heart of the book (more on that in a moment), two other longer essays, two short stories, and thirteen other bits of miscellaneous writing of varying lengths. I found most of the short essays unremarkable. Stephenson uses a walking desk because sitting is bad for you that sentence contains basically all of the interesting content of one of the essays. I think it takes a large topic and some running room before Stephenson can get up to speed and produce something that's more satisfying than technological boosterism. That means the most interesting parts of this book are the three longer works. "In the Kingdom of Mao Bell" was previously published in Wired and is still available. Some Remarks contains only excerpts; Stephenson says that some of the original essay is no longer that interesting. I had mixed feelings about this one. Some of the sense of place he creates was fun to read, but Stephenson can't seem to quite believe that the Chinese don't care about "freedom" according to his definitions in the same way and therefore don't have the same political reaction to hacker culture that he does. This could have been an opportunity for him to question assumptions, but instead it's mostly an exercise in dubious, sweeping cultural evaluation, such as "the country has a long history of coming up with technologies before anyone else and then not doing a lot with them." A reminder that the detail with which Stephenson crams his writing is not always... true. Stronger is "Atoms of Cognition: Metaphysics in the Royal Society 1715 2010," which covers material familiar to readers of Stephenson's Baroque Cycle. The story of Newton, Leibniz, their rivalry, and the competing approaches to thinking about mathematics and science was my favorite part of that series, and in some ways the non-fiction treatment is better than the fictional one. If you liked the Baroque Cycle, this is worth reading. But the highlight of the book for me was "Mother Earth Mother Board." This is a long essay (50,000 words, practically a small book and the largest part of this collection) about the laying of undersea fiber-optic cables. Those who have read Cryptonomicon will recognize some of the themes here, but there's way more to this essay than there was to the bits about undersea cables in Cryptonomicon. It's mostly about technology, rather than people, which puts Stephenson on firmer ground. The bit about people reads more like a travelogue, full of Stephenson's whole-hearted admiration of people who build things and make things work. There's a bit of politics, a bit of history, a bit of tourism, and a lot of neat trivia about a part of the technological world that I'd not known much about before. I would say this is worth the price of the collection, but it too was previously published in Wired, so you can just read it online. Those reading this review on my web site will notice that I filed it in non-fiction. There are a couple of stories, but they're entirely forgettable (in fact, I had entirely forgotten them, and had to skim them again). But, for the record, here are short reviews of those: "Spew": This originally appeared in Wired and can still be read on-line. The protagonist takes a job as a sort of Internet marketing inspector who looks for deviations from expected profiles. While tracing down an anomaly, though, he finds another use of the Internet that's outside of the marketing framework he's using. It's unlikely that anyone who's been online for long will find much new in this story. Some of that is because it was originally published in 1994, but most of it is just that this isn't a very good story. Stephenson seems to have turned up his normal manic infodump to 11 to satisfy the early Wired aesthetic, and the result is a train wreck of jargon, bad slang, and superficial social observation. (3) "The Great Simoleon Caper": Originally published in TIME, this story too is still available online. It's primarily interesting because it's a story about Bitcoin (basically), written in 1995. And it's irritating for exactly the same reason that Bitcoin enthusiasm often tends to be irritating: the assumption that cryptocurrency is somehow a revolutionary attack on government-run currency systems. I'm not going to get into the ways in which this doesn't make sense given how money is used socially (David Graeber's Debt is the book to read if you want more information); just know that the story follows that path and doesn't engage with any of the social reasons why that outcome is highly unlikely. Indeed, the lengths to which the government tries to go to discredit cryptocurrency in this story are rather silly. Apart from that, this is typical early Stephenson writing. It's very in love with ideas, not as much with characterization, and consists mostly of people explaining things to each other. Sometimes this is fun, but when focused on topics about which considerably more information has become available, it doesn't age very well. (5) Overall, there was one great essay and a few interesting bits, but I wouldn't have felt I was missing much if I'd never read this collection. I borrowed Some Remarks from a friend, and I think that's about the right level of effort. If it falls into your hands, or you see it in a library, some of the essays, particularly "Mother Earth Mother Board," are worth reading, but given that the best parts are available on-line for free, I don't think it's worth a purchase. Rating: 6 out of 10

A few weeks ago I went to see Blade Runner: The Final Cut in a one-off showing at the Tyneside Cinema. I've only watched the Final Cut once and that viewing was a bit compromised, so it was nice to see it properly, and on a massive screen with decent surround sound too. Whilst watching it I saw something that I thought might potentially have been a visual reference to Scott's earlier movie, Alien. When Deckard is climbing onto the roof of the Bradbury building, there's a decorative motif that to me, looks very Giger-esque, biomechanical, a bit like a chest-burster.

I went back and took a screenshot from the Blu Ray at the same point. What do you think? As it happens, whilst the inner regions of the building in the movie are the Bradbury building (or at least the entrance hall), I don't think the upper exterior shots are.

Purge

There are a few other, well-known references to Alien in Blade Runner, although they are likely simply re-used effects rather than explicitly easter eggs. The display screen in Gaff's Spinner is re-used from the Narcissus (here's a comparison) and the ambience in Deckard's apartment also featured in the Nostromo's medical bay. Some enterprising person has put together a 12 hour session of that particular sound effect looping. There's a number of other comparisons and spots at this propsummit.com thread.

So, Sony caved in (according to Rob Lowe) and demonstrated that America lost its first cyberwar (according to Newt Gingrich). It should not surprise anyone, after the whistle blower Edward Snowden documented that the government of USA and their allies for many years have done their best to make sure the technology used by its citizens is filled with security holes allowing the secret services to spy on its own population. No one in their right minds could believe that the ability to snoop on the people all over the globe could only be used by the personnel authorized to do so by the president of the United States of America. If the capabilities are there, they will be used by friend and foe alike, and now they are being used to bring Sony on its knees. I doubt it will a lesson learned, and expect USA to lose its next cyber war too, given how eager the western intelligence communities (and probably the non-western too, but it is less in the news) seem to be to continue its current dragnet surveillance practice. There is a reason why China and others are trying to move away from Windows to Linux and other alternatives, and it is not to avoid sending its hard earned dollars to Cayman Islands (or whatever tax haven Microsoft is using these days to collect the majority of its income. :)

Inspired by "An ASM Monad", I've built a Haskell monad that produces brainfuck programs. The code for this monad is available on hackage, so cabal install brainfuck-monad. Here's a simple program written using this monad. See if you can guess what it might do:

import Control.Monad.BrainFuck
demo :: String
demo = brainfuckConstants $ \constants -> do
        add 31
        forever constants $ do
                add 1
                output

Here's the brainfuck code that demo generates: >+>++>+++>++++>+++++>++++++>+++++++>++++++++>++++++++++++++++++++++++++++++++<<<<<<<<[>>>>>>>>+.<<<<<<<<] If you feed that into a brainfuck interpreter (I'm using hsbrainfuck for my testing), you'll find that it loops forever and prints out each character, starting with space (32), in ASCIIbetical order. The implementation is quite similar to the ASM monad. The main differences are that it builds a String, and that the BrainFuck monad keeps track of the current position of the data pointer (as brainfuck lacks any sane way to manipulate its instruction pointer).

newtype BrainFuck a = BrainFuck (DataPointer -> ([Char], DataPointer, a))
type DataPointer = Integer
-- Gets the current address of the data pointer.
addr :: BrainFuck DataPointer
addr = BrainFuck $ \loc -> ([], loc, loc)

Having the data pointer address available allows writing some useful utility functions like this one, which uses the next (brainfuck opcode >) and prev (brainfuck opcode <) instructions.

-- Moves the data pointer to a specific address.
setAddr :: Integer -> BrainFuck ()
setAddr n = do
        a <- addr
        if a > n
                then prev >> setAddr n
                else if a < n
                        then next >> setAddr n
                        else return ()

Of course, brainfuck is a horrible language, designed to be nearly impossible to use. Here's the code to run a loop, but it's really hard to use this to build anything useful..

-- The loop is only entered if the byte at the data pointer is not zero.
-- On entry, the loop body is run, and then it loops when
-- the byte at the data pointer is not zero.
loopUnless0 :: BrainFuck () -> BrainFuck ()
loopUnless0 a = do
        open
        a
        close

To tame brainfuck a bit, I decided to treat data addresses 0-8 as constants, which will contain the numbers 0-8. Otherwise, it's very hard to ensure that the data pointer is pointing at a nonzero number when you want to start a loop. (After all, brainfuck doesn't let you set data to some fixed value like 0 or 1!) I wrote a little brainfuckConstants that runs a BrainFuck program with these constants set up at the beginning. It just generates the brainfuck code for a series of ASCII art fishes: >+>++>+++>++++>+++++>++++++>+++++++>++++++++> With the fishes^Wconstants in place, it's possible to write a more useful loop. Notice how the data pointer location is saved at the beginning, and restored inside the loop body. This ensures that the provided BrainFuck action doesn't stomp on our constants.

-- Run an action in a loop, until it sets its data pointer to 0.
loop :: BrainFuck () -> BrainFuck ()
loop a = do
    here <- addr
    setAddr 1
    loopUnless0 $ do
        setAddr here
        a

I haven't bothered to make sure that the constants are really constant, but that could be done. It would just need a Control.Monad.BrainFuck.Safe module, that uses a different monad, in which incr and decr and input don't do anything when the data pointer is pointing at a constant. Or, perhaps this could be statically checked at the type level, with type level naturals. It's Haskell, we can make it safer if we want to. ;) So, not only does this BrainFuck monad allow writing brainfuck code using crazy haskell syntax, instead of crazy brainfuck syntax, but it allows doing some higher-level programming, building up a useful(!?) library of BrainFuck combinators and using them to generate brainfuck code you'd not want to try to write by hand. Of course, the real point is that "monad" and "brainfuck" so obviously belonged together that it would have been a crime not to write this.

Last night I mostly patched my local copy of less to build and link against the PCRE regular expression library. I've wanted to do that for a while, and reading Raymond Chen's blog post last night made me try it out. The patch was small and pretty neat, and I'm familiar with GNU less having patched it in the past. But it doesn't contain tests. Test cases are hard. Many programs, such as less, are used interactively which makes writing a scaffold hard. Other programs suffer from a similar fate - I'm not sure how you'd even test a web browser such as Firefox these days - mangleme would catch some things, eventually, but the interactive stuff? No clue. In the past MySQL had a free set of test cases, but my memory is that Oracle locked them up. SQLite is famous for its decent test coverage. But off the top of my head I can't think of other things. As a topical example there don't seem to be decent test-cases for either bash or openssl. If it compiles it works, more or less. I did start writing some HTTP-server test cases a while back, but that was just to automate security attacks. e.g. Firing requests like:

GET /../../../etc/passwd HTTP/1.0
GET //....//....//....//etc/passwd HTTP/1.0
etc

(It's amazing how many toy HTTP server components included in projects and products don't have decent HTTP-servers.) I could imagine that being vaguely useful, especially because it is testing the protocol-handling rather than a project-specific codebase. Anyway, I'm thinking writing test cases for things is good, but struggling to think of a decent place to start. The project has to be:

Non-interactive.
Open source.
Widely used - to make it a useful contribution.
Not written in some fancy language.
Open to receiving submissions.

Comments welcome; but better yet why not think about the test-coverage of any of your own packages and projects...?

Monday morning, 1:45AM. Laura and I walk into the boys room. We turn on the light. Nothing happens. (They re sound sleepers.) Boys, it s time to get up to go get on the train! Four eyes pop open. Yay! Oh I m so excited! And then, Meow! (They enjoy playing with their stuffed cats that Laura got them for Christmas.) Before long, it was out the door to the train station. We even had time to stop at a donut shop along the way. We climbed into our family bedroom (a sleeping car room on Amtrak specifically designed for families of four), and as the train started to move, the excitement of what was going on crept in. Yes, it s 2:42AM, but these are two happy boys:

Jacob and Oliver love trains, and this was the beginning of a 3-day train trip from Newton to Seattle that would take us through Kansas, Colorado, the Rocky Mountains of New Mexico, Arizona, Los Angeles, up the California coast, through the Cascades, and on to Seattle. Whew! Here we are later that morning before breakfast:

Here s our train at a station stop in La Junta, CO:

And at the beautiful small mountain town of Raton, NM:

Some of the passing scenery in New Mexico:

Through it all, we found many things to pass the time. I don t think anybody was bored. I took the boys exploring the train several times we d walk from one end to the other and see what all was there. There was always the dining car for our meals, the lounge car for watching the passing scenery, and on the Coast Starlight, the Pacific Parlor Car. Here we are getting ready for breakfast one morning.

Getting to select meals and order in the train restaurant was a big deal for the boys.

Laura brought one of her origami books, which even managed to pull the boys away from the passing scenery in the lounge car for quite some time.

Origami is serious business:

They had some fun wrapping themselves around my feet and challenging me to move. And were delighted when I could move even though they were trying to weight me down!

Several games of Uno were played, but even those sometimes couldn t compete with the passing scenery:

The Coast Starlight features the Pacific Parlor Car, which was built over 50 years ago for the Santa Fe Hi-Level trains. They ve been updated; the upper level is a lounge and small restaurant, and the lower level has been turned into a small theater. They show movies in there twice a day, but most of the time, the place is empty. A great place to go with little boys to run around and play games.

The boys and I sort of invented a new game: roadrunner and coyote, loosely based on the old Looney Tunes cartoons. Jacob and Oliver would be roadrunners, running around and yelling MEEP MEEP! Meanwhile, I was the coyote, who would try to catch them even briefly succeeding sometimes but ultimately fail in some hilarious way. It burned a lot of energy. And, of course, the parlor car was good for scenery-watching too:

We were right along the Pacific Ocean for several hours sometimes there would be a highway or a town between us and the beach, but usually there was nothing at all between us and the coast. It was beautiful to watch the jagged coastline go by, to gaze out onto the ocean, watching the birds apparently so beautiful that I didn t even think to take some photos. Laura s parents live in California, and took a connecting train. I had arranged for them to have a sleeping car room near ours, so for the last day of the trip, we had a group of 6. Here are the boys with their grandparents at lunch Wednesday:

We stepped off the train in Seattle into beautiful King Street Station.

Our first day in Seattle was a quiet day of not too much. Laura s relatives live near Lake Washington, so we went out there to play. The boys enjoyed gathering black rocks along the shore.

We went blackberry picking after that filled up buckets for a cobbler. The next day, we rode the Seattle Monorail. The boys have been talking about this for months a kind of train they ve never been on. That was the biggest thing in their minds that they were waiting for. They got to ride in the very front, by the operator.

Nice view from up there.

We walked through the Pike Market I hadn t been in such a large and crowded place like that since I was in Guadalajara:

At the Seattle Aquarium, we all had a great time checking out all the exhibits. The please touch one was a particular hit.

Walking underneath the salmon tank was fun too. We spent a couple of days doing things closer to downtown. Laura s cousin works at MOHAI, the Museum of History and Industry, so we spent a morning there. The boys particularly enjoyed the old periscope mounted to the top of the building, and the exhibit on chocolate (of course!)

They love any kind of transportation, so of course we had to get a ride on the Seattle Streetcar that comes by MOHAI.

All weekend long, we had been noticing the seaplanes taking off from Lake Washington and Lake Union (near MOHAI). So finally I decided to investigate, and one morning while Laura was doing things with her cousin, the boys and I took a short seaplane ride from one lake to another, and then rode every method of transportation we could except for ferries (we did that the next day). Here is our Kenmore Air plane:

The view of Lake Washington from 1000 feet was beautiful:

I think we got a better view than the Space Needle, and it probably cost about the same anyhow.

After splashdown, we took the streetcar to a place where we could eat lunch right by the monorail tracks. Then we rode the monorail again. Then we caught a train (it went underground a bit so it was a subway to them!) and rode it a few blocks. There is even scenery underground, it seems.

We rode a bus back, and saved one last adventure for the next day: a ferry to Bainbridge Island.

Laura and I even got some time to ourselves to go have lunch at an amazing Greek restaurant to celebrate a year since we got engaged. It s amazing to think that, by now, it s only a few months until our wedding anniversary too! There are many special memories of the weekend I could mention visiting with Laura s family, watching the boys play with her uncle s pipe organ (it s in his house!), watching the boys play with their grandparents, having all six of us on the train for a day, flying paper airplanes off the balcony, enjoying the cool breeze on the ferry and the beautiful mountains behind the lake. One of my favorites is waking up to high-pitched Meow? Meow meow meow! Wake up, brother! sorts of sounds. There was so much cat-play on the trip, and it was cute to hear. I have the feeling we won t hear things like that much more. So many times on the trip I heard, Oh dad, I am so excited! I never get tired of hearing that. And, of course, I was excited, too.

Wow. 3G delta. I haven t booted this laptop for a while I think I m finally ready to make the move from gnome2 to gnome3. There are bits that still annoy me, but I think it s off to a good start. Upgrading perl from 5.10 to 5.14.

First of all, good news, MirBSD is not vulnerable to The Heartbleed Bug due to my deliberate choice to stick to an older OpenSSL version. My inquiry (in various places) as to what precisely could leak when a vulnerable client connected to a n n-vulnerable server has yet to be answered, though we can assume private key material is safe. Now the bad news: while the CA I use and a CA I don t use offer free rekeying (in general), a CA I also use occasionally refuses to do that. The ugly: they will not even revoke the certificates, so any attacker who gained your key, for example when you have been using a certificate of theirs on a Debian system, will be able to use it (e.g. to MITM your visitors traffic) unless you shell over lots of unreasonable money per certificate. (Someone wrote they got the fee waived, but others don t, nor do I. (There s also a great Twitter discussion-thingy about this involving Zugschlus, but I won t link Twitter because they are not accessible to Lynx users like me and other Planet Debian authors.)

I ve been using GoDaddy privately for a while, paid for a wildcard certificate for *.mirbsd.org, and later also at work. I ve stopped using it privately due to current lack of money. Occasionally, for n n-wildcard gratis SSL certificates for HTTP servers. Startcom s StartSSL certificates are unusable for real SSL as used in SMTP STARTTLS anyway, so usage isn t much.

Now I ve got a dilemma here. I ve created a CA myself, to use with MirBSD infrastructure and things like that X.509 certificates for my hosts (especially so I can use them for SMTP) and possibly personal friends (whose PGP key I ve signed with maximum trust after the usual verification) but am using a StartSSL certificate for www.mirbsd.org as my GoDaddy wildcard certificate expires in a week or so (due to the aforementioned monetary issues), and I d rather not pay for a limited certificate only supporting a single vhost. There is absolutely no issue with that certificate and key (only ever generated and used on MirBSD, only using it in Apache mod_ssl). Then, there s this soon-to-be tax-exempt non-profit society of public utility I m working with, whose server runs Debian, and which is affected, but has been using a StartSSL certificate for a while. Neither the society nor I can afford to pay for revocation, and we do not see any possible justification for this especially in the face of CVE-2014-0160. I expect a rekey keeping the current validity end date, and would accept a revocation even if I were unable to get a new certificate, since even were we to get a certificate for the society s domain from someplace else, an attacker could still MITM us with the previous one from Startcom. The problem here is: I d really love to see (all of!) Startcom dropped from the global list of trustworthy CAs, but then I d not know from where to get a cert for MirBSD; Globalsign is not an option because I will not limit SSL compatibility to a level needed to pass their quality test possibly GoDaddy, ISTR they offer a free year to Open Source projects no idea about one for the society but it would solve the problem of not getting the certificates revoked. For everyone. I am giving Startcom time until Friday after $dayjob (for me); after that, I ll be kicking them off MirBSD s CA bundle and will be lobbying for Debian and Mozilla to do the same. Any other ideas of how to deal with that? I d probably pay 5 for a usable certificate accepted by people (including old systems, such as MSIE 5.0 on Win2k and the likes) without questioning most of the time, I only serve public content anyway and just use SSL to make the NSA s job more difficult (and even when not I m not dealing with any payment information, just the occasional login protected area). By the way, is there any way to access the information that is behind a current-day link to groups.google.com with Lynx or Pine? I can t help but praise GMane for their NNTP interface. ObFunfact: just when I was finished writing this wlog entry, I got a new eMail Special offer just for you. from GoDaddy. Sadly, no offer for a 5 SSL certificate, just the usual 20-35% off coupon code.
