Hvad i alverden sker der? Jeg hørte om den historie i Nyhederne på p3 i morges

Er folk simpelthen for fede og lade til at bo på 4. sal? Det er jo alt alt alt for langt ude!

*forarget*

Så er der godt nyt!

Ihvertfald folk folk som jeg der har fået en Outlook stukket i hånden på arbejde, men som også er glad for google calendar.

Jeg har installeret den, og det kører super. Det fede er imodsætning til de ical exports jeg har lavet, så er der styr på de danske bogstaver også!

So, progress is slow, and currently I’m looking into the base “architecture” of the show. I’ve been looking into different ESB’s as in:

• Mule
• OpenESB
• Apache ServiceMix

Im pretty hooked on using SQS for queues which Mule supports out-of-the-box. On the other hand is it tempting to code it my self. But then again. Ill take ages to make it robust enough.

So currently I’m trying to choose between Mule or code-it-myself.  Today I’m on the Mule side

As everybody knows, you need to take care of all technical desicions before designing or anything. So i’ve decided to use maven2 and eclipse for the project. (see my last post)

 Maven2:

I use maven at work, and I kinda got used to it. My expirence so far has been way more positive than my humble ant attemps during my bachlor thesis. Thats a good reason, right?

Eclipse:

I never used anything else than eclipse, so that was an easy choice. And I’m most certainly going to use Checkstyle and Findbugs and probably the eclipse-jutils project. I know that there exists “EE” plugins for eclipse too, so I might get som help there too.

Yay. More decicions done!

I got all these ideas in my head of things I would like to try. This is my wishlist/todo/nicetohave list:

• Try out the possibilites of Amazon Web Services, including EC2, S3, SQS and SimpleDB if possible
  • Whats the hype about?
  • What kind of effort does it take to make it scale
  • It should be as intelligent as possible. Ip’s, roles,dynamic scaling up/down, failover?
• Theres so many interesting software “things” that I would love to fiddle with
  • Scala on a appserver together with maybe groovy and java stuff
  • Glassfish
  • Websphere/DB2
  • Mule ESB or what about Open ESB
  • OSGi things

That should be able to keep me busy for a while

Jeg synes faktisk det var overraskende hurtigt de håndværkere gav op

Timitech

Beyond3D(Rys) wrote an article (almost a series!) about the history of the magic fast inverse square root found in for example the quake code. With the explantions it doesn’t seem quite that much as magic. As this pdf says, its not magic at all(page2)

The history article is all about paying homage to the author(s) and finding the origin. And it really is very very slick way of doing it. The article even uses this as an example of why it’s good that games and software gets release as open source in some form.

I’m just wondering: Why isn’t there any comments in this very sleek code?

If it was me using übercool constants for nice approximations in my code I sure would hope i would comment it!

Så har jeg også fået googledesktop.

Nu ejer google ca. alt hvad jeg har på diverse af mine maskiner. Det er noget af en fest!

Google desktop plugins er nu så meget sejere end yahoo-widgets. Jeg elsker de små korte beskeder man får hele tiden med updates på ens rss-feeds, emails og lign. Og TODO listen er god!

(jeg er så meget google-fanboy)

YetAnotherPostOnJavaClosures

So, I fell over some articles with both the words closure and java in them this week.

It was this article about JavaFX closures.

Since I’ve done some of my non-mandatory classes in my stud.scient. days (like the last 4years) it kinda woke my interest.

It seems like lots of things has happend in the Java world since I last had any real interest in it (somewhere around 1½ year ago).

• Java 6 and 7.
• Scripting languages on the JVM, like Scala and Groovy. Scala looks quite interesting in my opinion.
• And all the stuff that I’ve been ignoring when coding small things in Java 1.4 SE and having fun with generics in Java 5 SE.
  • Like for example J2EE, the bean concepts and Application servers and everything
  • Spring
  • Hibernate
  • JUnit
  • Test-driven-development

Maybe “fell over some articles” is a bit inaccurate. I’ve actually been trying to catch up. My main focus has been on the things I needed in my day-to-day work. That included JUnit and Unit-testing, Spring and the Application Server Enterprisy way of doing things.

Luckily I already spent some time reading up on the concept of SOA.

There is a ton of material online about all these things. Currently(as in the past year) there’s alot of talk about feature request for Java 7. Including closures. I tried to do a “quick” catchup on the subject and decided to share my findings with the world:

As far as I gather there currently exist two proposals:

• CICE – Concise Instance Creation Expressions by Josh Bloch, Doug Lea and Bob Lee
• BGGA – Gilad Bracha, Neal Gafter, James Gosling, Peter von der Ahé

and as in any other good war on the internet, it seems like we are at a point where religion is the turning point. The CICE people believes that the BGGA is “overly complex”, and will alienate users by “pushing the complexity of the language beyond the point where Joe Java can’t use the language anymore”
Another interesting twist is the fact the Neal Gafter – who I see as the current “main-man” behind BGGA, is working at Google as well as Josh Bloch and Josh Blach is the JCP representative for Google as pointed out by Ricky Clarkson (and down played by Neal Gafter).

So no real catfight there. But among the readers there’s a very Web2.0-ish involvement in the debate. Lots of evangelists on both sides. (I’m a BGGA’er myself! To me it seems like CICE is like sitting between two chairs). Among these debates and blogentries there’s lots of interesting reading (and hearing; podcasts).

Apart from the other links in this post I recommend:

• Gafter with closure examples
• Gafter with prototype for javac and a rewrite of fork/join code to use closures.
• (Actually all of Gafters blog is very interesting if you like programming language issues)
• JavaPosse podcast. (BGGA people as well)
• IBM on the debate: Java theory and practice: The closures debate

UPDATE: If you need the real thorough easy understandable walkthrough this is a very nice talk by Neal Gafter

If you need even more reading try some of these googlesearches:

• Comments to Gafter and closures
• Josh Bloch and Closures
• Gilad Bracha andClosure (Actually i really like his blog all in all. Just the name and Im sold “Computational Theology”. Too bad it’s discontinued, but hey, he still writes a bit on Blogspot)
  

ADVARSEL: Buzzwords og partisk indlæg!

Jeg har den store glæde at kunne præsentere mig selv som en af de få rå:

Ægte Eliteprofessionel!

ComputerWorld interview med vores administrerende direktør

At kommentarene til den tilhørende artikel ikke er helt så fine kan ikke ryste mig

Man kunne måske mene at eliteprofessionel måske er lidt meget buzzword, men det bakker faktisk meget godt op om hvordan det mærkes at arbejde hos Netcompany. Et konsulentfirma som ved at deres værdi ligger i den summerede værdi af medarbejdere.

Jeg kan kun sige at det er et dejligt sted at være, og har indtil nu været meget inspirende at være en del af “showet”.

Jeg sidder sammen med mange kolleger hos PFA og er javaudvikler i Produktions-Support. Dvs. vi holder infrastrukturproduktionen i luften. Før, under og efter nye releases med hotfixes, bugsøgning, nyudvikling og mange andre fine ord. Jeg har aldrig før prøvet at være med på så store projekter og slet ikke på så store udviklingsprojekter. Voldsomt spændende må jeg sige.

Derudover har vi brug for folk (lige som resten af IT-branchen) men jeg kan med mine 2½uge på bagen ihvertfald på det varmeste anbefale at arbejde for Netcompany

Jeg brugte selv lidt tid på research inden jeg var til samtale. At google dem og søge efter dem på diverse sites(CW, Børsen) er ok spændende:

• DIKU om administrerende direktør Carsten Gomard
• Ernst & Yong – Entrepreneur of the year
• Administrerende direktør Carsten Gomard i Søndagsavisen
• Version2′s top10 i forskellige kategorier. Ouch en lav plads i “God balance mellem arbejdsliv og privatliv”

Derudover er der jo altid netcompanys site som faktisk har meget spændende om karriere i Netcompany.
