>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 :-)

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

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?

>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!

>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.

Look what I found this week-end. Only 150SEK – great stuff!

>This is kind of cool: http://flickrvision.com/.

>Today is the last day we’re accepting project registration submissions to the Qt Centre Programming Contest. If you want to participate and still haven’t submitted your entry, hurry up to make it before midnight (CET) tonight!

>It has been a week since I last blogged – and there are lots of things going on. Here is a quick summary:

– Book-wise, we’re currently in both tech review and copy editing – meaning that I get documents to look at from all directions. I’m trying to be structured, but sometimes it feels like there is too much coming in and too little getting done. Also, I seriously need to get the appendixes done. If you have a project that you feel would fit (either a class library or a development tool), comment or mail me (e8johan, using gmail).
– Work-wise, I’ve finally started to prepare for my first training sessions. I’m going to Denmark and Stockholm to teach Linux on Xilinx platforms. Will be fun.
– Work-wise II, I attended a great course called “efficient consultants” in Ängelholm last week. A good, balanced, material for the course, superb trainer (Lucas from Retorium) and a very nice evening getting to meet some of the guys from our Lund and Stockholm offices.
– Life-wise, Åsa and I are celebrating our second anniversary today. Hooray!
– Life-wise II, I will be celebrating my 28th birthday on Wednesday.
– F1-wise, great work of Kubica to finally out-qualify Heidfelt. A sad day for Heidfelt but a great fourth for Kubica. Also, congratulations to Hamilton for the championship lead. I’m just wondering if he can handle a change of luck – he can’t stay on top through an entire season…
