Snowing again in Berlin. We should probably just rewrap our gifts and have Christmas again tonight ;)
It appears I might have been a bit too optimistic compiling ATLAS for Core2 in jblas. SSE3 code fails on older processors... :(

RT @headius: I want a javac with local type inference, closures, optional args, multiline strings, reflective invocation, and < 100k dist.
I was just convinced by @thinkberg to move to 1.0 for the planned 0.3.1 release (hopefully tomorrow), with 64bit win after the holidays... .
Replying to @CLINT
Reading ars for years now, this is maybe the 5th design change. Do you remember the black/white button? :)
Replying to @CLINT
Good question ;) Guess I'll miss the three featured stories at the top... Oh wait, I think you have them sliding now on the right...
Finally got ubuntu netbook remix running on my LG netbook with wlan and everything. Ridiculous how happy that makes me... :)
Replying to @nealrichter
Yes, that's right. Ken also says he tries out most things in C, not C++. I liked the book a lot!

Finally got the rt3090 wlan working with Linux 2.6.32 and ubuntu, but then grub "forgot" the Windows XP paritition #fail
Getting declines for JMLR review requests almost faster than I can send them... . Next try tomorrow... .
Thunderbird 3 puts all folders into offline mode by default, downloads everything. I guess mail servers will suffer around the globe...
@edoules I see... . I was just surprised, when it decided to install gcc from sources. Took about 3h, and gave me "gcc-mp-4.3" but no "gcc"
Just so that I get this correctly: Apple has the most controlled platform, but macports still compiles everything from scratch?
This week I spent like 2 1/2 days on grading student papers, and two full afternoons on reviewing... . Hopefully less load next week... .

Rewriting some of the @twimpact stuff in Java. After all the prototyping in Ruby, Java feels almost light, probably I know what I want.

Inlined media is quite nice... . Apart from that, my echofon Firefox plugin is just as useful... .

Replying to @alisohani
Ah, interesting. I didn't know that project. Thanks for the pointer.
Looking at java-gnome as a drawing replacement for Swing. Problem is, gnome's moving so fast, I can't even compile on debian stable... .:(
@edoules No, it's that I never find time to properly archive my emails. So now I have 8000+ emails dating back to 2007 in my inbox... .
8500+ mails in my inbox must be a technology problem... . Can someone please come up with a new UI paradigm for dealing emails?
Replying to @ChrisDiehl
Haven't had time to work on the configure script for jblas to compile under Mac OS, though.
RT @twimpact: New server's running nicely now, in particular after we've turned off the statistics "background" processes. ^MB
Does #nosql really boil down to patching something together from a key-value/graph/XML store and lucene indices???

On a more positive note, "Coders At Work" is really a lot of fun to read. I recommend it to anyone who's done any amount of coding!
Somebody stole the rain cover of our kid's bike seat. I guess that's the same kind of person who would steal a kid's sweets. >^(
Hm... If you think Andrew Gelman's blog is too high-volume for the #machinelearning feeds, let me know!
1
Just received my copy of "Coders At Work". Somehow I expected another book, but this still looks interesting ;)
Replying to @alisohani
Cool! Pass it on and let me know if you have any more suggestions/comments.
Fiddled all day long with Java serialization, Ruby marshalling and Sun's gridengine to get "parallel each's" but didn't quite get there...
I think I actually like @echofon's new feature to coalesce several updates into only one portrait being shown.
Replying to @ogrisel
Ok, no problem, I think if there is no new content, nobody will see. In case the RSS feed changes, you can let me know!
Thinking about splitting my Machine Learning Feed into Blogs and Journals/Preprints. The latter just swamp the blogs... .
Haben gerade versucht als TU Businesskunden ein Ersatz-iPhone zu kriegen. Ist nicht vorgesehen :(
RT @twimpact: As of now, twimpact has processed 50,251,728 retweeting message since the beginning of July.

I see... almost any google wave invite scam we've seen at @twimpact is already suspended. Seems twitter is doing its homework :)
1
Really amazing how twitter's trending topics don't reflect retweet trends (see @twimpact). Where are all the google wave invite scams?
1
Groovy makes me reconsider my conviction that prog langs should be implemented "in the void" to have a fresh start with the object model.
Sometimes I wonder whether programming in Java only feels like being productive because you're typing these huge amounts of code... . ;)
2
Marc Toussaint just gave a very interesting impromptu talk about a new idea he's working on. Almost forgot how interesting research can be;)
I definitely have to move away from blogger. Editing is a real pain, and you'll end up having <br/>s everywhere :(
1
Oh great, the @twimpact retweet processor puts such a high load on the database that the actual crawler is dramatically slowed down... .
@ryotat Sorry to hear that about your NIPS papers. In my case, papers claimed as being very similar were so only on a buzzword level :(
@mdreid Also no NIPS paper for me... . Though I could've been happier with the reviews... .
So is this finally going to be the day when I start reprocessing all the tweets in @twimpact? We'll see... .
1
Been debugging our cluster's file server config for the past 3 days. Hopefully, everything's stable now.
Today's task list: taking care of my daughter (slight cold), and submitting a project proposal. Ah, the joys of being a father/researcher ;)
Replying to @the_real_r2d2
we're currently working on an improved alg for matching the retweets. That should cut down on many retweet bots... .
RT @twimpact: Did you know that you can filter retweets by language or change the trending interval when you click on "top retweets"?
Replying to @ryotat
Good to see you've rediscovered your twitter account. Also let's me train my Japanese a bit again!
Hm... It's time I bring the improved @twimpact retweet crawler online. A bug leads to @nfl_games being parsed as "nfl" and "games" :(
Replying to @jimtill
Concerning the twimpact scores: Yes, we've been collecting data for only for about amonth now.
twitter's API definitely got more picky after the attacks from last week. Fixing minor glitches in the @twimpact crawler.
1
More specifically, the whole TU Berlin network is down :( RT @twimpact: The whole network access of our hoster is gone. #fail
Home from vacation. One day, we had an invasion of lady bugs on the beach. Didn't know those things could BITE!
Summer reading: "JPod" by Douglas Coupland and "From Molecule to Metaphor" by Jerome Feldman
Twitter Search API seems to be under stress again. Many servers are lagging seriously behind...
Replying to @jruby
topics: How about Java <-> Jruby integration, activerecord-jdbc & friends, rails deployment (glassfish, jetty, etc.), and ffi?
1
Timeout issues were more complex than I though at first. Checking whether it's fixed now, but will report in my blog about it!
Twitter search seems to be up again, but it seems tweets from during the downtime are missing... .
twitter's search API has neglected since_id for the last few days, now it refuses to return results when it thinks since_id is too recent
Seriously, sungrid docs read like legalese: "The share of the system to which any user or user-group, or project or project-group, is enti..
Reading through sungrid documents for improve job scheduling on our cluster. Would like it to be less abstract and enterprisey... .
Just submitted my NIPS paper. Roughly nine hours till the deadline and already a paper ID well over 500... .
1
Same thing happened to me... RT @martinfowler: Sign that I'm a Ruby nerd: use irb when I need a calculator
Replying to @mdreid
I had a few more ideas, but none of them matured to a point where submitting would make sense...
Number of active NIPS projects down to one. At least, that one should be a "sure submit" ;)
Replying to @ogrisel
No parallelization so far, only on the level of CV-resamples :( I'm using a patched version of the Java version of LIBSVM
Deutsche Bahn: Reservierung ungültig, Zug verspätet, Anschluß verpasst, späterer Zug verspätet und überfüllt. #fail
almost through with jblas 0.2. Can now build "fat-jars" and static libs. Will check on Win XP and home and then release soon.
Replying to @jakehofman
@ogrisel I guess interfacing Java to Fortran code becomes even more complex with sparse matrices...
Replying to @jakehofman
@ogrisel netlib lists some libs for sparse matrices. No idea which ones are active. MTJ also supports sparse matrices AFAIK
1
Workin on jblas, I'm learning more about linking with "ld" than I ever wanted to know... ;)
1
Replying to @jakehofman
jblas currently has no support for sparse matrices (haven't needed them so far), but it's definitely next on the list.
Replying to @ChrisDiehl
Yes, together with a Java matrix lib which is uses the native ATLAS libraries. Took a time to build up infrastructure, though...
1
Cooking up support of "fat-jars" for jblas. Does anyone know what os.name is on various platforms?
Had a great time at our two day group retreat. Got some good ideas for NIPS projects. (I guess it's this time of the year)
1
Hm... something is wrong with tweetdeck. Won't start up anymore after I updated to 0.25... .
Managed to move WinXP to larger disk using ubuntu + gparted + grub-install + gedit. Linux FTW!
Looked at various large scale learning methods all day long... . Makes more fun than you'd expect at first.
Still haven't fixed config on WinXP for jblas. Major upgrade of my home box got in the way... .
Remaining jblas task is to try compilation under Windows. Can only do that at home, unfortunately... .
Replying to @ogrisel
We're thinking about that right now. Probably BSD to keep things simple. Build process is currently ant & Makefiles... A bit messy
Impressive how a day of uninterrupted work can do for you. Made much progress towards jblas 0.1!
1
Installed Adobe AIR on Linux. More things magically work than I expected. But, no round windows... . :(
Benchmarking my new method against SVMs... . Quite suprised that SVMs become quite slow once you include model selection... .
1
Whoa, it's been a while... . Anyway, about a month before lectures for the summer term start. Trying to get a preprint out... .
Replying to @headius
I know that you have readline (via jline), but it lacks, e.g., backward search, which is very useful. Looking forward to 1.2!
For the last time this winter, it's Teaching Wednesday: Grading homework and preparing tomorrow's lecture.
Playing around with our new servers. Matrix-Matrix-Mult. went from 3500 MFLOPS peak on my laptop to 7500MFLOPS on the server. Crazy!
Replying to @mdreid
Your post brought 6 new subscriptions in the last 3 days. Interesting. Seems Alex Smola is experiencing similar things.
Now I realize just how dependent I became of the internet. But Paul remarked that 100 years ago, electricity might have been as unreliable.
Finally, the internet guy will drop by tomorrow to fix my internet at home. Only took 8 days to send somebody over.
This week has "teaching" and "project proposal" written all over it. Oh wait, that's what I actually get paid for ;)
No internet@home and my ISP is being unresponsive. What again was wrong with client-side software?
Seems the weather has followed me from Switzerland. Winter wonderland in Berlin. Very nice!
Back from our small winter vacation. Plane landed in heavy snow, that was a first for me. Back home, heating took hours to start up. Brrr.
