RQuantLib updated

A new RQuantLib package just went out to the incoming directories of CRAN and Debian. It contains minor updates reflecting the new QuantLib release 0.3.8 from last week. In particular, we now have a proper configure.in check for Boost which I lifted pretty directly from the one in QuantLib's configure.in. Still no new code in RQuantLib, unfortunately.

Minor Slashdot effect

Quantian made it into the tail end of a Slashdot cover story that was posted yesterday late afternoon. The following chart from my MRTG logs pretty clearly show when the story appeared, and when it fell off the front page.

Website hits while Quantian appeared on the Slashdot title page

Nice to know that the long-meant-to-be-retired box acting as the static webserver took it all in a breeze,

Quantian 0.6.9.2 dvds available at cheapbytes.com

Cheapbytes just replied back to the quantian-general list announcing the availability of Quantian version 0.6.9.2 dvd available pre-made for $11.99 plus shipping. A good alternative for those without broadband, patience or access to a dvd burner.

Otherwise, the bittorrent tracker page at U of Washington rocks: 40 completed transfer in the few days since the announcements, compared to 89 for last month's 0.6.9.1, or the whopping 288 downloads of 0.5.9.4 which sum up to almost half a terabyte. Gotta fill the fiber ...

Quantian 0.6.9.2 released

A new release 0.6.9.2 finished uploading earlier today. It is available from the usual sites at the University of Washington, at Debian's Alioth site. It should be available at Greg Warnes' machine at Yale once that machines becomes visible again.

This release is the second one based on Knoppix 3.6 and brings numerous updates:

  • added over 1.2gb (compressed) by adding virtually all packages from the CRAN and BioConductor archives for the R statistical computing environment -- giving Quantian unparalleld support for statistical computing, data analysis and graphical methods via the R environment and language;
  • several new packages labplot, dia, subversion, tla, python-matplotlib, python-gdal, and more;
  • new upstream versions R 2.0.1, and of many other applications;
  • and numerous other package updates.

More information in the Quantian changelog once I get a chance to update it, and general info is as always at the Quantian pages.

Hmmmm

Service really has been dropping, as noted most recently in this entry from October. Today it dropped around 10:00am, and didn't come back until I got home. Power-cycling the modem didn't help, so I called Comcast and obtained a reasonably clueful and patient service rep. I dodged the question whether I have a router, manically flipped cables and stuck the windows laptop from work back in. The service did in fact come back once that machine started making request. I have to try explict dhcp re-lease request from the Linux gateway next time.

The rep recommended getting another broadband router -- replacing this cheap 3com CM29220 I aquired via Techbargains.com with a Motorola 5100 or 5120. Any opinions on that?

Anyway, sincere apologies to anybody who may have tried to look for Quantian or this blog.

Pre-made dvds of Quantian 0.6.9.1

Right after the Quantian 0.6.9.1 release was announced, Mark Walker wrote in to say that BudgetLinuxCDs.com now has both dvds of Quantian 0.6.9.1, 0.6 (aka the 0.5.9.4 release that finalised the 0.5.9.* test releases) as well as the previous cdrom-size release 0.5.9.2.cd. All three are accessible via this page, but make sure you pick the right version and size.

Two days ago, Cheapbytes sales informed me that they have 0.6.9.1 available as well.

Two new HOWTOs for Quantian

HP48/49 Emulation on the Tungsten

Ever since I got my Tungsten C, I had been intrigued by one particular application for Palm OS 5 that was listed on PalmOpenSource.Com: the Power48 emulator for HP calculators. The problem was that the emulator required actual roms from HP. While these are available at HPCalc.Org, they needed to be installed in a particular way on the SD card. Which posed two problems: I didn't have an SD card, and when I tried to copy the rom files onto somebody else's SD card as a test, it seemed like the digital rights management software embedded in the SD card, in conjunction with the Windoze box on which we tried that, kindly prevented me from doing that, or at least in the way needed for Power48. So we called that a draw.

More recently, I noticed a 16 mb SD card for a whopping $2.99, shipping included, on the always help TechBargains site. So I ordered one, and got it today.

And lo and behold, it now works. I first tried to transfer the files via Card Directories, a little Palm app to place files anywhere on MMC or SD cards. Didn't seem to work, though.

After upgrading to the newest version of Power48, I sort-of learned from the README that a) the HP roms needed to be converted -- for which one needs to employ a Windows binary, and having the work laptop home proved useful for that, and b) that these thusly generated files needed to be installed under Windows too -- pilot-xfer did indeed fail.

And lo and behold, having done that, Power48 now works and I have three new (emulated) calculators.

Tradesports down ... and up

Following the election polls and bets had become a recurrent habit over the last few weeks. Below is the current intraday chart from Tradesports / InTrade taken a few minutes ago during this election night, courtesy of the Bloomberg terminal and using symbol 'IPREBUSH INDEX'.

Bloomberg chart of Bush contract, with service breakdown

It shows the wild swing in the traded price of the 'Bush elected' contract over this afternoon and evening ... up to the point when all prices went to 1.0, and back up just moments ago. Was that a denial of service attack? Server overload? Operator error?

Quality of service. Sort of. Maybe.

A few days ago, I had been pondering how the Comcast service had been remarkedly trouble-free over the preceding weeks. Well, and sure enough, that thought alone must have brought on the evil gremlins as we appear to have been off the web for several hour last night, as well as for most of the morning until around 2pm local time -- as is pretty easy to check from the various server logs, in particular smtm and http.

To those have tried to access these pages, or the Quantian ones, my heartfelt apologies. The best I can offer for such time would be ... the Google cache. Sorry for any inconcenience. One day I may look into real hosting, in the meantime this will have to do, in particular as the last few gripes are all from over a year ago.

Frank Lloyd Wright Race 2004

Gorgeous morning here in Chicagoland, and a perfect setting for the 2004 Frank Lloyd Wright Race in Oak Park.

The race switched back to a 5k and 10k. Lisa did the 5k, and was quite happy with herself. I tried to run the 10k rather aggressively which didn't go to well overall. My mile splits increased quite a bit after mile 2, but the total of 44:35 is still not too shabby with a 7:11 min/mile pace.

Chicago Marathon 2004

So today was the day -- after some four month of an ever-increasing training program, I attempted my very first marathon. Fantastic day: sunny, warm, no clouds. And a *lot* of spectators which makes it a lot of fun. I fell into an all too common trap and started faster than I should have. I'll blame my three buddies from the running group who were shooting for 3:20. I "paid" for this just as you're supposed too on the last six or seven miles: heavy legs, and more and more walking at the water stops. But I got where wanted to get to and crossed the finish line below my target of 3:30h and a hand-stopped 3:28:58.

This picture is from mile 11 and marked the first meeting with Lisa and our girls. I was obviously still in pretty good spirits

At mile 11 of the 2004 Chicago Marathon

We have two more, including one at the very, very last turn on top of the Roosevelt Road bridge, but it's not as up close and fun.

R 2.0.0 now in Debian

It's this time of year again, and the bi-annual GNU R release brings in a wider than usual list of changes as indicated by the new major release version 2.0.0. One change in particular, lazy loading, promises to be most useful, if only for faster startup times.. Unfortunately, the internal code changes also triggered two ugly bugs that seemed to appear only in the pbuilder chroot builds I made. After a couple of frustrating days spent trying different things, Brian Ripley kindly supplied a patch earlier today. This allows us build R, and the core 'recommended' packages, in the chroot environment used by the Debian autobuilders.

So after some further testing, packages of R 2.0.0 are now on the Debian servers and should be in unstable tomorrow. Because of the new internal interface to R packages, older packages will not load. Users can either call update.packages() directly, or wait a few days until we (as in Chris, Doug, Rafael, Steffen and myself) get the various r-(cran|bioc|omegahat|other|noncran)-* packages rebuilt under 2.0.0. We will try our best to have them all updated by Sunday.

Chicago Half Marathon 2004

Another gorgeous day here in Chicago, especially at the Lakefront, and around U of C where the Chicago Half Marathon takes place. This may be my favourite race as the course is set on such a nice combination of running along the parks near campus, and the (beautiful especially when car-free as for the race) Lakeshore Drive along the water.

The race went well, and I ended up running considerably faster than during the previous half-marathons with a pace just under 7:20 min/miles for a total of 1:36:01.

Quite right

The widely-read and rather influential Walt Mossberg was reviewing Windows security in today's column and concluded
Bottom line: If you use Windows, you're asking for trouble.

As they say, truer words have never been spoken... Other than recommending OS X in no uncertain terms, he listed a host of required add-ons to make that one dominant OS cope with its own lack of security.

Email woes

Looks like email to me is travelling rather erratically through the debian.org domain. Given that some of the (supposedly) incoming mail is entirely predictable from web archives of the respective lists I am subscribed too, it would appear that I have not gotten everything that went out in the last few days. Worse, a few fresh Debian bug reports haven't made it to me either. I hope the Debian listmasters and admins can do their magic and improve the flow soon, their work is surely appreciated.

Compiling afio under Cywgin

Here is a simple patch against the current afio-2.5 sources, derived mostly from an older patch from Japan against 2.4.7. This allows compilation of afio under Cygwin by simply calling make, no further config needed.

I sent it upstream to Koen, maybe it'll show up in a future versiom.

Quantian 0.5.9.4 released

A new release 0.5.9.4 was uploaded to the servers at the University of Washington, at Debian's Alioth site and at Greg Warnes' machine at Yale. This release may become the final 0.5.9.* release and get relabelled 0.6; work should soon commence on a Quantian based on the new Knoppix 3.6.

This is a maintenance and bug-fix release over 0.5.9.3, yet still contains a rather large number of changes:

  • another 50 more GNU R packages from CRAN and BioConductor providing unparalled depth for statistical computing with now about 440 R packages;
  • added Gnumeric and LyX back in;
  • added pcb to complement GNU geda;
  • added the Alliance VHDL, a complete set of free CAD tools and portable libraries for VLSI design which includes a VHDL compiler and simulator, logic synthesis tools, and automatic place and route tools, see the Alliance website (suggested by 'Joe'; Debian package generated from rpm by alien(1))
  • added a slew of astronomy-related packages suggested by Gopal Narayanan: setiathome, tkseti, xplanet, xplanet-images, saoimage, gpsim, gnucap, oregano, icom, xcircuit, vipec, xsmc-calc, transcalc
  • added two more data visualization packages: xd3d suggested and packaged by Marco, and QtiPlot also suggested by Marco;
  • and made a few production fixes suggested by Marco: prepare md5sums to enable 'checkcd' option; suppress 'modules.conf newer' message by touch(1)'ing it; add new bootsplash screen; use Marco's corrected minirt24.gz and minirt36.gz boot images with ext3 patch and scsi module aic79xx.

udunits

udunits is a tool and library for physical unit conversion, written by the folks at UCAR, the University Consortium for Atmospheric Research. Udunits is used by an eponymous CRAN package for R, as well as by other tools such as NetCDF, also with its own CRAN package.

To cut a long story short, udunits code is a little old-ish and its Makefiles would need an overhaul. I have made a local package you can find here for now, and would like for someone to adopt this and make it a proper Debian package. The Makefiles needs a rewrite: only a static library is built, prefix indirection doesn't work completely, the manual pages go into the old locations of /usr/man and possibly more little things.

So the package is there, I'll put it into the next Quantian release, but I can't maintain it beyond that. This would make a nice project for a sciences grad student who actually uses NetCDF, and hence udunits.

Updated Ggobi and Rggobi packages

Ggobi, a neat data visualization tool, is a bit of a Debian step child due to its almost-but-not-quite-FLOSS AT&T license. Our autobuilders don't touch it as it is flagged non-free, even though AT&T did try to to make it as free as they thought they could. Interestingly, Graphviz has the same problem yet many more packages, including some core ones like apt don't mind interfacing that non-free API.

Anyway, the Rggobi interface package for calling Ggobi from GNU R had a fails to build from source bug which only came up now when the amd64 crowd tried to build it (as this dependent package is a semi-step child in contrib). Since the last package release, I had tried to upgrade to the newer Ggobi 1.0.0-beta, but failed to build either the currently package Rggobi or the newer 1.0.0 of Rggobi against it -- so the old version will have to be it for a while. A friend has a saying for the peticular nature of these build problems: BOINJ, and I guess we need to make that BOICA now. And now, I won't reveal the joke via the blog.

Back from vacation

We were gone to a small town on Lake Huron for a week and two weekends, and returned last Sunday. Vacation was great: finally finished a novel I had been stuck in for way too long, read another, ate a lot, drank like a fish, run some 60 miles in seven days, hang out on the beach with the kids, and stayed clear of computers and all things online for a week. Felt good, actually.

Since then I spent last week catching up on a mountain of email, fixing a few bugs and upgrading a few packages, and doing a few little things like getting the bike back from its annual inspection. No real programming work yet other than adding a few items to the Quantian TODO list; not sure when the next release will be. Beancounter needs an update too, hopefully soon.

And another new IP :-/

Now for the first time since December 2003, and following the March 2003 change, which itself suggests a nine-month pattern, Comcast assigned us a new IP address.

So I just edited the web form at gandi for the DNS of the .com address, sent a signed email to the 'change' bot at db.debian.org for the .net address, edited the configuration for bind, edited /etc/hosts, edited apache's httpd.config, and updated the IP address itself for the mail forwarder. Now all I need to do is wait for DNS to catch up :-/

Somewhat of a silly game, really. Maybe I should splurge for a real provider like Speakeasy?

Quantian 0.5.9.3 released

A new release 0.5.9.3 was uploaded earlier to the server at the University of Washington.

While nominally only a maintenance upgrade over 0.5.9.2, it still contains a rather large number of changes:

  • way more GNU R packages generated with a modified version of a script by Albrecht Gebhardt -- about 360 packaged are added from CRAN and BioConductor providing unparalled depth for statistical computing
  • an almost complete suite from the Debian-Med project for medical informatics (only CMS was left out, would Zope make sense for Quantian?)
  • the GNU geda electronics design software suite
  • the scalapack libraries and headers for parallel linear algebra in mpich, lam and pvm 'flavours'
  • loads of 'recommended' documentation packages
  • header packages for atlas3 and lam
  • upgraded throughout against Debian testing, with over 300 updated packages
  • Total size is now 1.5gb for the compressed iso image, corresponding to more than 4.4gb of uncompressed software.
  • also available are a new cdrom-sized version of 0.5.9.2 and a bootable iso of only 7mb, both contributed by Marco Caliari

Chicago Distance Classic Half Marathon

Ran this years's Chicago Distance Classic this morning. The format switched from a 20 km race to a slightly longer half marathon, with a new and improved route with lots of lake front running to boot.

The run was interesting: I was going pretty steadily at 7:20 min/mile until about mile 10 when I really needed to, um, go to the bathroom. I didn't quite get back to the same regular pace, unfortunately. Finish time was 1:38:43, for a pace of about 7:32, which is once again a little bit faster than the previous two half marathons this year.

Bug fix release beancounter_0.7.6

Moments ago, a new beancounter version has been uploaded to Debian, CPAN and my beancounter pages; the the Freshmeat beancounter record was also updated.

This release contains a small but annoying fix to setup_beancounter which was mistakenly pointing to a version of beancounter in /tmp. Following a hint from CPAN Testers, a dependency on Fiance::YahooQuote was added to Makefile.PL. Lastly, a contributed script by Joao Antunes Costa is now included in the source distribution.

YANCC (Yet another nice Cringely column)

Robert Cringely has another neat column on broadband exploits. He's singing the praises of a $99 router device to get redundant dsl and cable modem service. I had wondered about that too, doing it directly in a linux router/gateway box, but then I don't run a biz from home, but only a bandwidth consuming hobby or two.

The whole column is very refreshing for the dismissive tone of his SBC comments. Cringely is a much smarter geek that I'll ever be, and he overcame SBC in neat ways. I'll probably remain scarred from the long troubles we had getting service after we came to Illinois ...

Rmetrics uploaded

Following Diethelm's announce on the r-help and r-sig-finance lists of Rmetrics release 191.10057 and its initial upload to the CRAN archive for GNU R, I just sent this as a follow-up:
Many thanks to Diethelm for the new Rmetrics release 191.10057, and to the CRAN masters for including it in the archive.

I have updated the initial packages that had been prepared for and included in Quantian 0.5.9.2, and just completed uploading them to Debian's incoming/ directory. As brand-new packages, they will have to wait the customary ten or more days until the ftpmasters insert them into the archive. Once that has happened, they will be apt-get'able from you favourite mirror.

In the meantime, you can fetch sources and i386 Debian packages manually (sorry, no apt-get support here) from

http://dirk.eddelbuettel.com/code/rmetrics/

Happy 4th of July, Dirk

Very, very nice to have this exciting set of packages in Debian, and to be helping along in its transfer from the land of Windoze-only.

Back from Boston

The slides from my Usenix talk on Quantian as a distributed computing environment, given earlier this afternoon, are now up.

It was a hectic trip: arrived late yesterday and caught a little bit of a BoF session before working some more on the slides til the early morning (ahem). Got up, registered, listened to Eric Allman of Sendmail fame on Spam, then to Martin on Debian and MIA -- while I worked on the slides (ahem). Then left the conference and met some Bostonian friends for lunch, back to the conference, listened to some other 'Extreme Linux' presentations, gave my talk and rushed back to Chicago. I should have allowed for more time because what I managed to see was all good. Also odd to know that there were other Debianers and not having met any...

Quantian 0.5.9.2 released

A new release 0.5.9.2 has just completed uploading to the server at the University of Washington.

This is a maintenance upgrade over 0.5.9.1, but still contains a rather large number of changes:

  • Expanded bioinformatics support with (most of) BioConductor release 1.4 as well as Debian packages for bioperl, biopython, hmmer and emboss from Matt Hope's Debian repository at UNSW
  • Yet more CRAN packages for R: lme4, matrix, psy.
  • Included for the first time are four pre-release Debian packages from Diethelm Wuertz' Rmetrics project for financial engineering and computational finance: fBasics, fSeries, fOptions, fExtremes.
  • Other new packages include the qemu emulator as well as a variety of science packages such as kalzium, celestia, starplot, openbabel, chemtool, xtide, viewmol, achilles and blast2.
  • Upgraded throughout -- 430 updated packages mostly from Debian testing (with a few from unstable), including x11, gcc et al, perl, apt/dpkg/dselect, R, lam, cernlib, geant, gretl
  • An error was fixed in r-cran-rsprng which had not been compiled built correctly.

Bug fix release beancounter_0.7.5

A few minutes ago, a new beancounter version has been uploaded to Debian, CPAN, my beancounter pages and the Freshmeat beancounter record was updated too.

This release contains a small correction to the documentation for the database connection password, a new test routine to check whether database connections can in fact be made, and a hook from setup_beancounter to actually use that test.

Quantian 0.5.9.1 DVDs available at cheapbytes.com

Cheapbytes just emailed me saying that they have the most recent Quantian version 0.5.9.1 dvd available pre-made for $11.99, following last week's early listing of budgetlinuxcds.com who came in at $7.50.

The Cheapbytes.com page also lists Mfg. Price $19.99. Being the 'manufacturer' here, I don't think I ever said anything about prices. Let alone offered to sell any. Oh well.

Downers Grove 5 miles

Had learned late last night from my running group buddies that there was a 5 miles race to be had to start Father's Day in style, so off we went on a sunny and surprisingly cool morning. The course is somewhat tricky with a few hills thrown in for good measure. Finished at 32:21, or about 6.52 min/mile which is fine given the nice barbecue dinner we had been treated to at friends the night before.

Boot a 1gb iso image directly from a windoze partition

A few people were surprised to see the most recent Quantian come in at 1.1gb, which does of course exceed the size of a cdrom. There are few good reason for this (such as the large and growing number of good packages to include, the fact that software tends to grow rather than shrink, and that we like documnentation too), and it is unlikely to change.

So burning dvds is a good idea, as is running directly from a linux partition as outlined in the lilo booting HOWTO. That said, there are of course always a few machines which simply cannot be turned into dual-boot or linux-only. For these, we have a very nice new solution: just drop the iso image onto c:/ as, say, quantian.iso, and then all one needs is a boot cdrom (such as the current clusterKnoppix cdrom from which Quantian is derived), and then use

   knoppix bootfrom=/dev/hda1/quantian.iso
at the prompt.

Clean, simple, easy. Doesn't cause heatburn or pimples, and worked on my trusted Thinkpad T23, a machine from work which knows only win2k. The full writeup is now up in the new windows booting HOWTO.

Quantian 0.5.9.1 released

A new release 0.5.9.1 was transferred to the server at the University of Washington. This is a new release, with many exciting changes such as
  • from Knoppix release 3.4: new hardware detection, captive-ntfs to write to partitions from those other systems, KDE 3.2.2, and a switch to isolinux for the boot process
  • from clusterKnoppix: updated 2.4.26 kernel with 'testing release' openMosix patch (and kernel 2.6.6 without openMosix), a variety of openMosix-related software updates such as gomd, chpox, tyd and update-cluster
  • from Quantian itself: updated software throughout, a number of new CRAN packages for R (including snow aka the 'simple network of workstations', a simple layer to make pvm and mpi easily accessible for distributed statistical computing), axiom (another computer-algebra package), cernlib (a large suite of programs from the CERN particle physics lab) and more.
  • custom artwork as Ed Pegg Jr kindly created a background image for us!

Fifth Third Half Marathon 2004

Got up real early and drove out west to St Charles (for about 45 minutes) for the 2004 Fifth Third Bank Half Marathon.

The race was, um, shall we say, different? I guess after living for more than a decade somewhere along the great lakes, I don't get much exposure to elevation. Real moutaineers will laugh themselves silly about this chart

(elevation chart)

but us flatlanders are struggling. At least I was. The other, um, interesting part was that they had a couple of rather randomly placed mile markers which made sticking to a pace--already challenging with the hills--even harder.

Anyway, I was hoping to finally break 1h 40min, and trying to stick to 7:30 min/miles which worked so-so until I got really tired after mile 10 and more or less gave up on the idea. Only to then find that the last turn gave rise to short stretch straight downhill, and with the clock in sight, and the chance to make it, I finished as if I was chased by the devil himself. The announcer saw me coming, looked up the bib number and tried to announce 'Dirk Eddelbrrrrrgggh'. Not sure if then swallowed his tongue . Anyway, I made it by about six second to finish at a hand-stopped 99 min 54 secs. We'll see what the chiptime says. I'm pumped, though.

And I didn't mean to gripe (other than about the useless mile markers). It is a beautiful course all through the subdivision, starting with the starter castles, and eventually settling down along the Fox river to finish in 'downtown' St. Charles. I think I'll be back next year.

New 'R in Finance' list up and running

Yesterday, I sent this note to the r-help list:

Thanks again to everybody who participated in the finance sessions at the recent useR! 2004 conference. During the discussions, the idea of a mailing list for R and Finance came up. Thanks to Martin, such a list has now been created and can be accessed via the page

https://www.stat.math.ethz.ch/mailman/listinfo/r-sig-finance

from which subscription requests can be made using the usual confirmation system employed by the mailman software. Everybody interested in 'Finance' (we will try not to be too picky regarding definitions) and R us cordially invited to subscribe. Also feel free to forward this message to interested colleagues.

Subscriptions are trickling in at a steady rate, let's hope we get this list to be a helpful and lively forum.

Bike The Drive

Today was the annual Bike The Drive on Chicago's scenic Lakeshore Drive. And what a blast--six to eight lanes of traffic totally free of cars, and filled with thousands of cyclist doing 15 or 30 miles along the lakefront.

I even cycled in from home, which added another 2 x 12 miles or so for a total of around 54 miles. Got lucky and arrived home just before a massive thunderstorm hit

Soldier Field 10 Miles

Ran the inaugural Soldier Field 10 Miles race this morning. Soldier Field is the newly renovated (and somewhat controversial looking) home of the Chicago Bears of the National Football League, and the Chicago Fire of Major League Soccer.

The race started outside Soldier Field, went down the Lakefront towards Hyde Park, and back to finish inside the stadium -- which was neat. Running conditions were pretty ideal---coldish and cloudy---which helped with yet another personal best of 71:59 or more than four minutes faster than the Lakefront 10 Miles race last month.

Indianapolis Mini Marathon 2004

Ran the Indy Mini Marathon this morning on a gorgeous sunny May day. Eighty plus degrees, and not a cloud in the sky. For once I managed to pace myself well, and I ran a pretty steady race averaging 7:38 min/mile with a decent kick at the end of a fast last mile. My hand-stopped time was 1:40:11, and the results page, which surprisingly is up a few hours after the race is over, has me at 1:40:12. Quite happy with that.

I should stress that this race is really well organised. Tons of bands along the route, lots of spectators, lots of water stations, and supposedly 30,000 runners registered. The lap on the Indy 500 tracks was somewhat silly -- no wind at all, and hot. Incidentally, that was my slowest mile split. Overall, it was bit excessive to drive 190 miles each way just to run 13.1 miles, but heck, with the weather that nice, it was a fine day off.

Lakefront 10 Miles

Just back in from the Universal Sole 10 miles race at the lakefront. It had rained all night, and the weather forecast had predicted a not so pleasant morning -- but it turned out to be closed to perfect. Mostly sunny, almost no wind, temps in the high 50s. With a time of 76:18, I shaved more than five minutes off last year's time which I'm rather happy with given that I had a latent cold all week, and spent most of last night coughing. I guess I'm ready for the Indy Mini in two weeks.

Sweet

Just got the $100 refund check for my Tungsten. Given that Newegg wasn't listed as an official seller in the refund program by palmOne, I gave this submission an expected value of maybe $20. Now the total cost of the Tungsten C is less than what I paid a few years ago for the Handspring Visor it replaces. So shall I go and spend the monies on the GPS receiver currently on sale ?

By the way, I'm really quite pleased with the Tungsten C. It feels less sluggish (400 MHz Strongarm cpu), it has ample memory (64mb), the screen is terrific (but harder to read outside) and the 802.11b wifi is neat. Drawbacks are the above-average weight, the fact that there are way too few open hotspots (but it's nice enough not have to go upstairs to check email) and that documents to go and the adobe pdf converter require windoze. So I only get to use that at work ...

Herbie Hancock

Just back from seeing Chicago's own Herbie Hancock at the CSO. Very, very nice -- playing with his quartet (Gary Thomas: fl, ts; Scott Colley: b; Terri Lyne Carrington: dr) with special guest Wayne Shorter on tenor and soprano.

I guess it has been almost a decade since I saw him last back in France, but he clearly is one of my all-time favourite musicians. The repertoire tonight spanned material from his awesome 60s recordings on Blue Note to the newer material from the 90s, and it was all delivered in such a lyrical way that is really unique to him. Seeing Wayne Shorter live was also neat; I don't think I've seen him since maybe 1987 or so in London. Gee, I'm starting to sound really old. Anyway, Hancock will play one more next week with Dave Holland and Jack DeJohnette. I should see if I can still get tickets...

Jane Monheit

Last night, we went to the pretty North Shore Center for the Performing Arts in Skokie, a 'burb north of downtown Chicago, to see Jane Monheit. She played a really nice, but rather short, set of just over an hour, and one encore. The auditorium appeared to be of an average age of least twice hers, if not twice mine (well, maybe not that old) and didn't quite get into it, despite the material being rather heavy on standards.

Which is too bad, because she is really good, with a very wide vocal range and unbelievable control. She did a few pieces from her previous albums as well as some that should come in the fall -- she recently signed with Sony and just finished recording a first album for them. Lisa got us awesome seats in orchestra pit -- second row, to the side. Close up and personal. Real nice, all told, and just too bad the audience didn't get more into it.

Nice concert

Cassandra Wilson was back in town at the CSO on Friday. Decent concert with a lot of 'rhythm' -- driven by Teri Lynne Carrington on drums and the very impressive Jeff Haynes on percussion. A mostly acoustic night with Reggie Veal on bass with Brandon Ross on guitar and banjo, the real surrise was Gregoire Maret on harmonica playing as if he was the lead trumpet or sax player in a classical quartet and quintet. The material was in large part from the latest (and most excellent !!) album, Glamoured, and well arranged. All the faster, funker pieces had a lot of drive to them. Unfortunately, where we sat towards the back of the main floor and under the balconeys, the sound was somewhat muffled. All in all a fine evening out.

A new release 0.4.9.5 has just appeared now on the servers at the University of Washington and the server at the University of Wisconsin / Madison. It is a bug fix release with relatively few changes compared to 0.4.9.4, but has
  • updated R packages based on the first pre-release of the upcoming 1.9.0 version, updated CRAN packages and a few new CRAN packages: multcomp, mvtnorn, relimp, and the uebercool rgl
  • updated Octave packages based on the just released 2.1.56, and a matching octave-forge release
  • improved support for Scientific Python, though scipy.test() still moans, we hope to sort that out shortly
  • the ftnchek package for Fortran'ers
  • but most importantly, we now have a custom logo for openmosixview in the KDE menubar -- thanks to Mathias Rechenburg for contributing this!

With Cebit coming next week, I'd suspect that the next Quantian release will be based on the Knoppix 3.4 that is to be released there -- but it may take a while until all clusterKnoppix and Quantian flow through.

Phil Homewood sent in a patch (that we extended minimally) which addresses this at least in the short term by adding a fix the ScrubData() routine. We divide new data by 100, and I'll need to add a fix for backpopulation.

Grrrr

I wasted most of yesterday chasing my own tail: After my new Tungsten palm arrived, I had set it up 'in bulk' by restoring what the so very useful jpilot had stored as a backup.

It turns out that this mightily confuses the AvantGo reader I am so used to. Despite several upgrade attempts from (gasp!) windoze and directly (nice hints are here and here (though you may need to be logged in) via pilot-xfer, it would sync nicely but never get the reader software going. At first I was confronted with 'AvGoPimPod1 not a shared library'. Deleting libmal and installing libsmal from the 'palm executables' bundle fixed that. But still no reader. It continued to babble about channels -- I guess that's their commercial product for intra-company news transmission.

Well, another attempt his morning fixed that. Deleting AGConnect, AvantGo and libmal before reinstalling them along with a new definition of the server in AGConnect did the trick. While the info is exactly the same as before, this seems to sail around whatever bug was blocking me before. I'm happy.

Now if only the other channels would use a smaller font just like the venerable Globe & Mail does so that one gets more mileage out of the neato 320x320 display...

While I was at work, FedEx did me the favour of delivering the replacenent for my aging Handspring Visor that was supposed to be here only by Monday -- a new and shiny Palm Tungsten C with wifi, loads of memory, and a (as far as PDAs go) blazingly fast cpu. We actually had a dinner party earlier, so I couldn't tend to it rightaway, but now, and thanks to jpilot, my backups are restored (though AvantGo seems to require a partially new installation driven from Windoze), the amazing pssh is installed and I'm blogging on a minuscule Palm keyboard sitting in front of the computer that I am connected to via ssh over wireless ip... I guess it passes the first test of usefulness.

Score tied at one all

Earlier today, and after reading Joerg Jaspert's rant on Debian Planet being at times too off-topic for him, I felt compelled to send him private mail as I happen to disagree with that point. Unfortunately, he and I didn't get much further than repeating our positions once over.

Back now at the computer, I just saw MJ Ray's riposte which I happen to, no surprise here, agree fully with. To me, one of the nicer aspects of Debian Planet is how it, at least occassionally, brings out the other, non-computing side of fellow Debianers. That is clearly not a bug but a feature.

Coincidentally, while running errands this afternoon, I listened to Chicago Public Radio (one of the very few remaining stations worth turning on) which carried an interview with a U of Chicago law prof on the origin of the word 'echo room'. His thesis is that people self-select themselves more and more into virtual communities. The main point here that these communities are all non-overlapping, so people simply reinforce prior beliefs and opinions as the only feedback they get is from people who, by virtue of the pre-selected, are likely to hold views very similar to their own.

Getting back to the prior topic, having non-Debian posts on planet.debian.net allows us to break the 'echo' pattern at least a little bit.

Simple html mode for .txt file in blosxom tree?

So I made a blunder omitting a closing " earlier, and the post got an foobar'ed. Working in the one and only editor, I am wondering if someone had some elisp magic to turn html mode on for a file ending in .txt provided it sits below a configurable top-level directory, i.e. my blosxom directory?

Right now, and for kicks, I manually turned html mode on and off again as we don't formal document header for a blosxom input file. Better than nothing, but far from ideal.

About PolicitalCompass.org

Jordi's post on planet debian lead me to politicalcompass.org, which is good fun for a few minutes.

And silly at the same time -- as it is about quantifying the arguably rather multidimensional aspects of, gasp, several social sciences discplines onto a two-dimensional plane (spanned by the, as far as the site goes, outdated 'left / right' metric, applied to an Economics axis, as well as polital liberalism vs authoritarian axis). Given that I was nerdy enough to endure schooling all the way to a doctoral degree in quantitative methods in social sciences (Econometrics, if you cared to ask), I have quite some empathy for the undertaking (as I also care a lot about empirical work if and when it is done well), as well as countless objections. But then again, we just did that mostly for the fun of it, didn't we?

And no, I'm not going to say how I scored on these two dimensions of 'economic left/right' and 'authoritarian / libertarian'. But if I told you that I've read the Economist for close to two decades, you'd get an idea.

The main new feature is support for the lightweight and fast SQLite database backend (while PostgreSQL, MySQL and ODBC are of course still supported as always). A few minor bugs were fixed, and several additional documentation files were included for good measure.

Another new beancounter release

Robert Schmied sent me a nice set of small patches which correct a few minor issues. The most important one is probably that getting volume information is now stored as well during backpopulation.

Now available on the beancounter pages, and should soon be on the Debian and CPAN mirrors.

Oops: beancounter_0.6.4 release half-missed

Robert Schmied just pointet out to me that the 0.6.4 release of beancounter was half-messed up. While I uploaded the Debian package and sources, my website still pointed at 0.6.3. Likewise, I seem to have forgotten to upload it via PAUSE to my CPAN directory.

Both these oversights have now been corrected.

Speaking of brown paper bags

How self-referential. While blogging about the little blunder I had made forgetting to upload Steffen's packages, I noticed another one: the blosxom upload was botched. A fix was just upload. My apologies.

How embarassing!

Steffen Moeller had asked to sponsor two or three of his R packages. Fair enough, given that I maintain R itself as well as an increasing number of packages from CRAN, I can't really say no -- especially as his packaging was done well and straight along the recently posted Debian R Policy draft.

So I built those for him in December, even stuck them into the 0.4.9.2 release of Quantian I had prepared about the same time ... and then never uploaded them. Ouch. Shame on me, I suppose.

Steffen, being a nice guy, sent me a kind note today that he had prepared a new package based on a new upstream release of qtl, and gently reminded me of the RMySQL and DBI packages. Blush. Well, they are now on master, and even rolled RMySQL forward by a minor release. Or is that considered uncool? Another brown paper bag?

Quick blosxom patch upload, dpatch woes, and new maintainer looming

Forgot to mention that blosxom 2.0-5 was uploaded yesterday eve after Alexander Zangerl had sent me a nice one line, or rather, 10-some byte :), patch to to support an new command-line option '-f conffile' building on one of my initial patches.

As a new maintainer for blosxom is looming (Salut, Pascal :), I tried to clean the package up and switch to dpatch ... only to fail miserably. I had converted another package of mine to the 'simple patch system' of cdbs, and that is soooo much easier to use. Oh well.

That was fast

Ordered a new box to replace our dual-amd, with which we continue to have random locks every couple of days, on Wednesday evening just before one of these Dell special deals expired -- it's their entry level server which has a nice Unofficial Dell PowerEdge 400SC FAQ.

Shipment was supposedly to be in three days from now ... yet the box arrived today! It boots Knoppix as well as my Quantian just fine. A pIV 2.8 GHz and a mobo with sata support, gigabit lan, graphics, sounds, whathaveyou all integrated along with a puny little disk and a laughable amount of Ram (order for a gb from crucial is on its way), it all came to just over $500 of which $100 should come back via a mail-in rebate.

Another Blosxom patch in a revised Debian package

Turns out that the previous patch didn't cut it quite yet -- GMT was hardcoded as a timezone. Debian merrily refuses to give in to ugly environment variables like TZ -- so the timezone is harder to get. Ivo Timmerman pointed out that there is a timezone plugin at the blosxom website. It only sets TZ to a pre-configurable variable though.

So I quickly added three more lines to call tzset and tzname, and now assign a tz variable which can be used in the rss format. One minor annoyance is that the setting itself is still in the flavour file /usr/share/blosxom/timezone -- so I dpkg-divert'ed mine.

If you see this via rss aggregation at planetdebian, it should show with a time of very early in the (UTC) morning whereas I type this at 21:00h Chicago time.

Blosxom rss patch in new Debian package

The patch by Matt Howard that was reposted by Ivo Timmerman just went into the 2.0-3 revision of the blosxom package. A minor man page fix is also included.

By the way, if someone wants to take over maintaining blosxom for Debian, drop me line.

New smtm version with automatic chart updates

A feature I had meant to add for a longish time finally made it into my smtm program: Charts now update automatically if you're in gallery mode (which can be enabled as a command-line switch, or via the Charts menu). Very nice for the intra-daily and intra-weekly charts, in particular for the index symbols like '^GSPC' for the SP500 which Yahoo! provides in real-time.

Enjoy -- Once the mirrors are updated, you can get it from both Debian as a package or source tarball, the CPAN Perl archive or via its Freshmeat page. Feedback welcome, as always.
