ncm throws about Accusations...
Is ncm talking about what I think he's talking about, namely LtU node #531? Subnode numbers, please!

While I'm on Nathan's post, I don't think think the Common LISP community has been ideological for a good 10 years or so. Sentimental, maybe, or perhaps Nathan's mixed up CL with scheme?

Avriettea's Meta &c
avriettea oberved:

I can't help but think that when people read these diaries between all the military stuff and my ranting about the wikipedia and the gun pictures and stuff that I am freaking a few people out. When you say in your previous entry, you'd love to own the Barrett M99 rifle, and then you have a friend in OSD, and you hate a bunch of people, I guess somebody could get the wrong idea. I hope that's not the case. I'm a pretty boring guy, I promise.
And I couldn't help noticing that avriettea's diary appeared on my edition of recentlog at rating 2.2... Well, that's now fixed. I don't like guns, but I can appreciate gun nuttery when it's done right.

2nd CfP: Structures and Deductions
It's four weeks away from our ICALP satellite workshop's submission deadline (ie. 15th April). Attempts to make waves:

  1. LtU node #582: The domain is proof theory, the theme is "Eliminate Bureaucracy", the LtU angle is that if we can eliminate bureaucracy from proof theory, then we open the floodgates to applications of proof theory to computer science. That's the theory anyway..;
  2. The SD05 wiki page at the consequently.org wiki; and
  3. an entry at my Slashdot journal.
I wonder if any of this will reach interested ears...

Two Fine Polemics

  1. The Poor Man on Christopher Hitchens (via Ted Barlow);
  2. Scott McLemee on James Atlas.

    What was it that happened Christopher Hitchens? BTW, he's touring with David Horowitz in June, London dinner tickets a snip at $???? (deposit $500), strictly first-come first-serve basis...

Recentlog
avriettea (shit fixing) and avriettea (discouraged): I'm really very impressed at the way you are going about changing things you don't like with Wikipedia. I think I'm going to have to apply your example with some of the lameness that irritates me. I half wished I cared enough about modern military technology to appreciate the work you've done with your edits. Good luck with "system shit" (=DB server?). Oh, and congrats with how the M$ interview went (news?).

While I'm thinking about Wikipedia, I worked on the Trust metric and Advogato articles and created the Raph Levien page. I'm guessing some recentlog readers might like to contribute...

Signs of a Sick Civilisation
lemonodor has got evidence that's hard to argue with.

It's been months since I've enjoyed reading an advogato diary entry so much...
Oops spelling correction...
Curry-Howard wiki
Greg Restall has started a Curry-Howard wiki called "Proof and Counterexample"; it seems to be some kind of consultation exercuse for his planned book. I am enormously happy to hear this, which I heard of via, where else?, Lambda the Ultimate.

An Answer, sort of
Thomas Ptacek pointed me in the direction of ent, which isn't quite the low resource estimator for gzip performanceI was after, but it's in the right sort of direction.

Fallibility
I've been making lots of assertions that turned out to be false in my last few diary entries. I'm feeling particularly raw about misidentifying the SYNTAX-CASE records implementation...

A Question
Is there a fast way of getting a reliable estimate as to how much compression to expect from gzip? By fast, certainly I mean much faster than gzip in terms of cpu cycles/swap space needed.

A portable-looking SYNTAX-CASE implementation...
...has been posted to a SRFI mailing list by Andre van Tonder. I think I will port this to librep.

Nonsense, as Neil Van Dyke pointed out to me. I linked to an implementation of records in SYNTAX-CASE, which I mistook for what I was after.... So, for the record, I don't know of a fairly portable SYNTAX-CASE implementation, by which I mean one based on a reasonably easy to integrate low-level macro facility.

Spread the word
Peter Seibel's Practical Common Lisp is-out will come out very soon, and can be preordered. Via xach, ... and correction via xach's other, me-correcting, diary.

Wonderful!
Scott McLemee, who is essayist at large for Inside Higher Education, writes very, very well. There's a faint echo of Christopher Hitchens' in his writing, and the same non-conformist involvement with Marxist doctrine, but from across a cultural gulf (the nature of their respective educations could not be more different; [Bio #1] [Bio #2]), and without the unnaturalness of Hitchens' recent politics. Some samples:

NotSoRecentlog
zhaoway seems to be surprised I read his diary entry: actually zhaoway's diary entires is one of the half-dozen names who get me to (semi- )regularly read recentlog.

Postscript: While I'm on the subject of Hitchens (again): When the glitter fades... is worth reading.

To joke or not to joke?
fxn links to Nathan Torkington's How to Title Your Talk. I hadn't heard of Nathan, but he's the author of the Perl Cookbook, which even a Perl outsider like myself is aware of, so obviously he knows something about marketing contributions.

Even so, I don't think his advice is sound. He claims that cleverness in making titles is often unwise, because cleverness falls flat in all kinds of other contexts. He's right to point this out, but he's wrong to say the risks in these other contexts always trump the potential benefits of being clever. Here's an enumeration of pros and cons:

  1. Pro: being clever can make your paper memorable. Philip Wadler would have been ill-advised by the conference organiser to change his title "Linear types can change the world" to something pedestrian like: "An application of linear logic to the problem of expressing stateful side effects in type systems";
  2. Pro mentioned by Nathan: being memorable can enourage some people who might otherwise not be bothered to read your abstract, download your PDF and/or attend your talk (rather than a parallel talk, a cool MPEG and/or chatting with someone in the coffee area);
  3. Con: People who don't share your sense of humour might be put off. I suspect Nathan, long-suffering conference organiser, had this in mind, but he didn't say this;
  4. Con mentioned by Nathan: one might run into the title in all kinds of context where one does not have access to the abstract and/or PDF, in which case one's reaction to the joke will simply be "Eh?".
  5. Pro or con? An apparent case of the above is search engine visibility: if your talk comes up in a list of search results, the roving eye may well pass your eye-catchingly clever title without realising it is relevant. On the other hand, I think cleverly titled papers get linked to rather more often than the pedestrian.

RecentLog
zhaoway: Funny, automake-like functionality was one of the original, long abandoned goals for my scol language. I might take a closer look at scons, hope the python advocacy isn't too intolerable...

Slow Motion Railway Disaster
Michael "Diary of a Nobody" Totten gets drunk with Christopher Hitchens. A truly excruciating story. Via Kieran Healy. Some highlights:
  • Sir Michael rides forth: But Hitchens had a defender, too. He had me;
  • He shares some down-to-earth wisdom: Believe me, you don't know what a tense political fight feels like until the person yelling at you is from a country you recently bombed and currently occupy;
  • You really had to be there: I put my face in my hands. None of this was what I wanted to hear, and it dragged on longer than I'm making it seem in the re-telling;
  • Eureka! Maybe they really didn't (and don't) completely understand how we differ from the colonialists and imperialists of the past;
  • So 'ere's to you, Fuzzy-Wuzzy: I respected them more, too, because they stood up to me and Christopher Hitchens. They are not servile people. They will never, ever, be anyone's puppets;
  • Grooovy! We're instantly on the same page on multiple levels all at once;
  • He's, like, totally tuned into where it's at: You can't afford not to read blogs,'' I said. ``Because of who you are and what you do for a living, you'll be hopelessly behind if you don't.
    ...
    ``Like I said, Christopher,'' I told him. ``You can't afford to be unplugged from the blogosphere."
  • A moment of intimacy... ``Angel,'' he said. ``Can I call you angel?''
American slang doesn't really have the right word for our brave correspondent, but British slang has the word pillock.

Odifreddi's book
Cameron Laird, who I have the idea has an advogato account though I can't find it, writes a nice plug for Piergiorgio Odifreddi's The Mathematical Century. Buy it, read it. (via lispmeister/Planet LISP). Odifreddi is also the author of Classical Recusion Theory, a masterful introduction to the area, with a very enlightening overview of the significance of Church's thesis.

Diary redux
Lot's of things I've been meaning to commit to my diary, little said:

  • I want to respond to Bill Clementson's very information packed post, that on the way put his case for not wanting to follow the definitions of concurrency at al I proposed. I also have had a nice email discussion with Dirk Gerrits on this topic;
  • Lots of things came up on LtU that I'd like to link/comment on;
  • Warning: political content will be appearing in this diary in the next few days: left-wing vs. right-wing political cultures, the political centre, and what I regard as the failure of the anti-war left to respond in a decent manner to the Lancet study.

He's Back!
ncm, compassionate sociopath and resenter of garbage collection, is an advogatan again! I've recertified him as master: sorry Nathan, I know it annoys you, but you do deserve the rating according to the criteria I've been trying to consistently apply.

Oop: better in theory than in practice?
This Lambda the Ultimate story seems to have provoked a not-too-unpredictable storm...
