  1. Re:Here we go again on Planetary Society Wants To Launch a Crowd-Funded Solar Sail · · Score: 1

    Failure is generally a necessary part of the process of innovation. As long as we take valuable lessons away, we should not be afraid of or ashamed of failure. If we simply gave up every time we failed at something or didn't try unless we were 100% sure we wouldn't fail, we'd never get anywhere in science and technology.

  2. First Launch on Planetary Society Wants To Launch a Crowd-Funded Solar Sail · · Score: 1

    The first test launch is actually just a few days away on May 20. You can watch it live at http://sail.planetary.org/miss....

  3. The Makings of a Speech? on Hackers In Space: Designing A Ground Station · · Score: 1

    I believe that hackerdom should commit itself to achieving the goal, before the next three decades are out, of landing a hacker on the moon and returning him safely to the Earth. We choose to go to the moon. We choose to go to the moon in 2034 and do the other things, not because they are easy, but because we p0wn...

  4. Re:strictfp on What Every Programmer Should Know About Floating-Point Arithmetic · · Score: 1

    Strictfp gives you more repeatability but less performance and generally less accuracy.

    strictfp can actually improve performance, depending on the CPU architecture and Java implementation. Think about it. If variables are stored in IEEE format and a different format is used for intermediate calculations, then there is converting going on and that takes time.

    The difference in accuracy is not significant in any practical sense. The IEEE formats were designed so as to divy the bits up between the exponent and the significand in a way that works for nearly every application.

    Its worth it for a Java developer to be aware of strictfp. We have all been sold on the slogan, "Write Once, Run Anywhere", but it really should be "Write Once, Run Anywhere...But Get Slightly Different Floating Point Results Unless You Use strictfp".

  5. Re:#1 Floating Point Rule on What Every Programmer Should Know About Floating-Point Arithmetic · · Score: 3, Informative

    If you think that every language except Java implements IEEE-754 to the letter, you are sadly mistakenly. That fact is Java can be used just fine for floating point work in most applications.

  6. strictfp on What Every Programmer Should Know About Floating-Point Arithmetic · · Score: 4, Informative

    This article should mention strictfp in the section on Java.

  7. Unanswered Question? on Google Launches Dictionary, Drops Answers.com · · Score: 1

    Do this mean I'm not going to get answer to this question on answers.com: http://wiki.answers.com/Q/How_do_you_know_when_its_time_to_poop

    Go have a look at mono (http://mono-project.org).

  9. Pi Joke on Happy Pi Day · · Score: 5, Funny

    What is the volume of a pizza of radius z and thickness a?

    Answer: pi*z*z*a

  10. Sure on Should Wikipedia Allow Mathematical Proofs? · · Score: 5, Insightful

    Of course they should allow proofs. Proofs are useful and factual information and proofs alone don't really "teach" mathematics are far as I'm concerned. They should take care to properly separate proofs from higher level information, as not everyone is interested in them.

  11. Hi on Ask Apache Software Chairman Greg Stein · · Score: 1

    Greg, How's your brother, Ben, doing and whatever happened to his game show?

  12. Nothing New on Remote Control for Humans? · · Score: 5, Funny

    Wives had had this for their husbands for years now.

  13. So... on Federal Court Shuts Down Pay As You Go Wireless · · Score: 5, Funny

    I guess the name "Freedom Wireless" is an ironic choice.

    ...we all start using IRC again.

  15. Pardon me for asking a stupid question, but... on IBM Donates Parts of Rational to Open Source · · Score: 3, Insightful

    What exactly does it mean to donate a software development process? Wasn't the Eclipse Foundation already free to use RUP for the development of the Eclipse environment? And couldn't companies using RUP already use the Eclipse environment for their projects?

  16. Well Since Its British... on Design Wanted For Antarctic Base · · Score: 1

    It should kick arse! If its going to be multiple stories it should have a lift. And they should give the construction workers some warm kecks but with a flap so they can baba. And there should be a lounge so the scientists can gas and have a fag. This base could be one heck of a gaff for those scientists! They should go the full monty and spend a few million quid.

    ...how long it will be before you'll be able to buy one of those compressed air launchers at rest stops in South Carolina along route 95.

  18. SQL Has Served Us Well on SQL, XML, and the Relational Database Model · · Score: 1

    My first professional coding job was to write financial reports in a mix of C and SQL. When I started learning SQL I was amazed how 10 lines of SQL could do what would take dozens of C code easily. I have since seen a number of highly successful projects use SQL-based databases. This article calls SQL a failure -- BS.

  19. Re:Von Neumann machines? on End of The Von Neumann Computing Age? · · Score: 1

    I think one of Von Neumann's most clever ideas (and most taken for granted today) is the idea of storing programs as numbers in memory. This was the EDVAC (Electronic Discrete Variable Automatic Computer) design. As an aside, some people think that the Von Neuman model was really the idea of Von Neuman Eckert, and Mauchly together and that Von Neuman wrongfully gets all the credit.

  20. Native Code vs. HotSpot on Java Performance Tuning, 2nd Ed. · · Score: 1

    I seem to remember seeing some benchmark that said that native compiled code was actually slower than the Hotspot JRE.

    Can any confirm this and/or explain how this is possible?

    I've been running Shrike for almost a week now, and, maybe its just me, but it seems like startup goes _so_ much faster than 8.0. Anyone else notice this?
