>10 PRINT "Hello World!"

>I’m just in a great mood today as my book, Foundations of Qt Development, is going to get printed today. Almost a year of hard work is coming to an end and I’ve just started my summer vacation. Nice to have some time of, and even nicer to be a proper book author and not just some article writer for Datormagazin :-)

>A call for help

On a side not, SpeedCrunch development has really been revitalized when the new maintainer, Helder Correia, took over.

>KDE 4 Alpha 2

>Ok, it has been days since the second alpha of KDE 4 was released so I’m late. Still, I’ve put together a small collection of screens where I’ve tried some of the new stuff in KDE 4. The alpha is really limited still, so hopefully the review of the next edition will be more interesting. In the mean time – check out the current state here: KDE 4 Alpha 2 test run.

>A long time ago…

I found some old code today.

!       Boundaries

       CHARACTER*60    BNDFN(1:15)
       INTEGER*2       CHKBOUNDS
       INTEGER*2       LOADBOUNDS

       INTEGER*2       BNDS
       INTEGER*2       CHKBNDS

       COMMON  /CBOUND/ BNDFN,CHKBOUNDS,LOADBOUNDS,BNDS,CHKBNDS

I just have to say that I love the code, in a painful kind of way.

        ELSE IF (STRINGCOMPARE(VARIABLE,'BOUNDFILE'//CHAR(0)) .EQ. 0) THEN
               IF (CHKBNDS .EQ. 1) THEN
                       IF (CHKBOUNDS .EQ. 0) THEN
                               LOADBOUNDS = LOADBOUNDS + 1
                       READ (VALUE, '(A60)') BNDFN(LOADBOUNDS)

                               IF (LOADBOUNDS .EQ. BNDS) THEN
                                       CHKBOUNDS = 1
                               ENDIF
                       ENDIF
               ENDIF

This was actually my first paid software job. I wonder what kept me going.

        IF(FILTER .EQ. 60) THEN
               /KILL("T3")
               /BUTTER("NOFILT","T3",2,0.0,100.0,1,1)
               /KILL("T2")
               /CONV("T3","T2",0,,,,,1)
               /KILL("T3")
               /BUTTER("T2","T3",2,0.0,100.0,1,1)
               /KILL("T2")
               /CONV("T3","T2",0,,,,,1)

So, any Trolls out there that know anything about any Fortran bindings for Qt?

>Finally F/OSS

>I’ve finally had time to do some minimal F/OSS work again – it has been months. I’d like to start by thanking Helder, Ariya and everyone else who have been working on SpeedCrunch 0.8. Yesterday evening I put together a Windows Installer for the 0.8 alpha release. Try it! Show it to your friends! Make your mum use it!

>Shopping for Books

>I just ordered a bunch of books – I hope that they are good. I feel that I need to get some good reference books instead of just Googling as soon as I need to know something. Perhaps I can find the time to do some reading during the summer…

Embedded Linux Primer: A Practical Real-World Approach by Hallinan. This one includes kernel debugging techniques as well as a good focus on memory technology devices and flash file systems.
Understanding the Linux Kernel (2nd Edition) by Bovet and Cesati. A good coverage of the different parts of the Kernel.
Linux Device Drivers (3rd Edition) by Corbet, Rubini and Kroah-Hartman. This is probably where I’ll spend 95% of my time when working with embedded Linux. The book only covers kernel 2.4, but it is still a printed reference and a good starting point.

All that is left now is to wait 5-7 days for delivery.
