Crashing Javac

admin — Sun, 04 Jan 2009 15:13:04 +0000

It seems that lately I have been crashing javac… An exception has occurred in the compiler (1.6.0_10-rc). Please file a bug at the Java Developer Connection (http://java.sun.com/webapps/bugreport) after checking the Bug Parade for duplicates. Include your program and the following diagnostic in your report. Thank you. java.lang.NullPointerException at com.sun.tools.javac.comp.Check.checkCompatibleConcretes(Check.java:1215) at com.sun.tools.javac.comp.Check.checkCompatibleSupertypes(Check.java:1567) at com.sun.tools.javac.comp.Attr.attribClassBody(Attr.java:2674) at com.sun.tools.javac.comp.Attr.attribClass(Attr.java:2628) [...]

From MikTeX to TeXLive

admin — Wed, 10 Sep 2008 08:35:57 +0000

Since I am stuck with Windows, I guess the viable solution for LaTeX is MikTeX. It had served its purpose well, untill recently, when out of a sudden, a XeLaTeX-based project I am working on either could not compile or the resulting PDF was partly unreadable. I reinstalled the whole thing, tried a few quirks [...]

Stuck with Windows

admin — Wed, 10 Sep 2008 08:23:42 +0000

For several reasons, I have been stuck with a Windows environment for the past two years. I am trully missing Linux… I recently tried VirtualBox but it crashed a few times and after that suddenly my network settings in the Linux Guest went bad. Since I was out of touch, I tried to re-read some [...]

Rise of the Community – Phase Two

admin — Wed, 03 Sep 2008 09:42:51 +0000

It is a few days ago that I volunteered to maintain scalap. Writing with Scala has been more than fun and I decided it was time to write for Scala. My time is limited, but the barrier has been, at some percentage, a psychological one. Dealing with the very stuff itself, is something to be [...]

Object-Functional Programming is Here

admin — Mon, 18 Aug 2008 09:11:16 +0000

In Computer Science, we have all been educated to recognize the terms Object-Oriented, Functional-Programming, Logic-Programming, etc. It is time for a new term to enter our vocabulary: Object-Functional Programming. It represents the fusion of object-oriented and functional-programming cultures and it happening right now, with its finest representative, Scala. I have been playing around with the [...]

Enter reflection, meet type unsoundness

admin — Sun, 17 Aug 2008 17:00:07 +0000

The theoretically-inclined may judge if the subject correctly characterizes the situation I am about to describe. At some point while programming a library (in Scala, of course), I thought it would be a nice idea to abstract over some compiler-powered magic regarding the handling of for-comprehensions, and in particular those compiled to foreach() calls. So, [...]

Language-Level LazyVals in Scala

admin — Thu, 24 Jul 2008 15:11:02 +0000

[This is from http://www.nabble.com/Question-on-lazy-val-td17678892.html] For what it’s worth, I fast-coded a hack that implements lazy vals at the language level, mimicking the compiler’s implementation. It turns out 120% slower that built-in lazy vals, if using the client HotSpot (default) and 40% slower if using the server HotSpot (java -server). It does not leak (?) and [...]

On Bananas and the Effect of Shotokan Karate on the Human Character

admin — Thu, 29 May 2008 09:09:40 +0000

In Greece, there is a term for under-developed countries: “Banania”. It is funny we have devised a term, for which the very first representative – you could call it a “reference representative” as in “reference implementation” in computer science terms – is our own: Greece. The other day, a close friend of mine had an [...]

Re: The Mysterious TreeMap Type Signature

admin — Thu, 24 Jan 2008 09:31:12 +0000

[This is a comment on the recent post The Mysterious TreeMap Signature by D. Spinellis, also posted in his blog.] Recently I had to delve into Java Generics quite deep, since I (as my search concluded) needed to use public class Foo<t extends Foo<T>> recursive constructs for a personal project (which by the way are [...]

Beyond Homo Sapiens Sapiens

admin — Tue, 22 Jan 2008 09:53:22 +0000

I think I was in late high school when it occurred to me that the next step in human evolution is the ability to understand/comprehend an abstract idea directly. Homo Sapiens Abstractus?
