Travel day


Yesterday was again a travel day, after only 2 weeks that I returned from San Francisco. This trip is not business though, I am visiting my family over the Easter weekend.

I woke up early at 7 am yesterday and after finishing packing (checked in for the flight and packed the night before) we headed to the airport.

I think the most difficult decision was which gadgets to take with me but eventually I just packed all in: Surface, iPad, Kindle and my Nokia Icon smartphone; except for my iPhone of course which is packed away in its box waiting to be wiped ever since I got my Windows Phone and my brother is really looking forward to getting it. :)

The first flight was short, only 30 minutes, we barely took off and then we were already landing.

We had to wait for 4 hours for the connecting flight and the weather was so nice outside but it was not enough time to take the train to the city so we had to stay at the airport and look how gorgeous it is outside from inside. *sniff*


My first stop was the duty free shop and I spent at least 1 hour there buying some souvenirs, sweets and I finally found fragrance-free face and eye creams that I am hopefully not allergic to.

There was a special exhibition at the airport displaying different clocks. We had some fun there!


There was plenty of time to have lunch at the airport too and I picked a small chicken soup only and we shared a dessert too.



The second flight went well and I finally had time to read my WCF book.


Although I love my Kindle, I have a lot of books on it and use it often, it annoys me that electronics are forbidden during take off and landing so I am allowed to use it only when we reach a certain altitude. I would practically lose at least 30 minutes during this 1.5 hours flight.

So I decided instead that I take this book with me and read it on the plane. I have to prepare for the MCPD exam anyhow and this was a perfect opportunity. I still have a long way to go till I am completely ready to take the exam and only 3.5 months time to prepare for it but I will slowly get there.

Our plane landed at 19 o’clock and we were finally in my home town after almost 3 hours drive with the car so that makes a total of 15 hours of travel with 2 planes and a car for a distance of 1500 km.

After a delicious dinner (lamb soup and deviled eggs) we had a great time catching up and telling stories till midnight.

I woke up at 6 am this morning because my puppy was looking for me and she was walking back and forth in front of the bedroom door. I couldn’t fall back to sleep but my puppy is now of course sleeping nicely. How evil is that? ;)

I think I convinced my mom to switch to Windows Phone 8 too. She has an Android and I showed her my new Nokia Icon briefly and she wants one now too! :)

We’re planning to have a late lunch today in the city in the afternoon and then go to the cinema to watch Grand Budapest Hotel. Tomorrow we’re going on a road trip to visit some nice places and I really hope that the weather will be nice because for now it is cold, cloudy and rainy. :(

//build/ 2014 Day 3 session recap

I have attended live the sessions described below on day 3 at the Build conference and these are my notes from these sessions. Some parts might not be easily readable or understandable (even for me Smile )  because the sessions were fast-paced and I tried to write down everything which seemed important to me. Nevertheless I hope that this brief summary is helpful to some of you.

  • D2d and Image Effects, DirectWrite on Windows Phone 8.1
  • Universal Visual Studio solutions
    • Samples on MSDN
    • Same code running on Windows and Windows Phone
    • Shared and specific project are pushed together and compiled
    • Sample: 99% shared code, specific include constants
  • Text in 8.1: color fonts for Emoji instead of bmp because bitmaps don’t scale well
    • These are just texts with color
    • No need for different bitmaps with different DPIs
    • Gradient not supported
    • Segoe UI/Windows Phone Emoji
  • 2D geometry
    • Complex rendering is CPU bound
    • Bitmaps need to be regenerated, don’t scale/rotate well
    • Optimization goal is to work on the GPU and to eliminate CPU, to find a balance between CPU and GPU
      • CPU for curve evaluation and tessellation => caching in Geometry Realization, reuse on GPU
      • GPU for antialiasing and brushing
    • Geometry realization is available also on Windows Phone
    • Use Geometry Realization with static geometry, depends on scale factors, only for transformations like translation, rotation, uniform scale.
  • Image effects
    • Memory utilization and startup time taken up by images
    • Quality vs. space trade-offs
    • Block compression by 4 bits
      • BC 1-3: DX 9+
        • BC 1: 4 bits/pixel
        • BC 2-3: 8 bits/pixel
      • BC 4-5: DX 10+
      • BC 6-7: DX 11+
      • Best is BC3 or BC1, depending if with alpha or not
    • JPEG YCBCR compression

Weekly Recap

Fitness & Nutrition

I think I can keep this part short since I didn’t go to the gym this week and did no sports whatsoever, except for walking home from the train station one evening because I missed the bus by one second. But the walk took only about 15 minutes so I don’t count it as a big workout, although it did help me relax and disconnect a bit from everything.

Nutrition-wise I haven’t been logging in MyFitnessPal, I started on Monday but then stopped and haven’t continued ever since. I just couldn’t find the time and energy to do it. I am swamped at work and I was fighting jetlag in the evenings. Nevertheless I tried to keep it healthy and do some serious portion control and just stop eating when I felt full. I hate to waste food but I am also proud of myself for saying no when I had enough.

This week has been obviously not ideal but I don’t think I can do a lot of damage just within one week, plus sometimes we just need a break.

I guess we all have periods where things just don’t go the way they should and I definitely miss exercising and seeing that I have met my calorie and macro goals perfectly after a day. All I can do is to try to do better in the near future.


I continued with my demo Windows 8 game app and I have some animations built in now too, I used Storyboard which is perhaps not the best way but I think it is good enough for the beginning.

I am still preparing for the MCPD upgrade exam and I am still at the part with WCF services. I watched lots of videos and I am now reading a book. I made a learning plan for the next few months and if all goes well I will be finishing with it till end of June. Last deadline for the exam is end of July so I hope everything will go well because I will come pretty close.

I started mentoring a colleague this week (first time mentoring so suggestions are welcome), she is doing her research paper in our department. We suggested multiple topics and she picked test automation. We are building the base now with OOP and C#, theory first and a nice small application afterwards to put the programming theory to practice. This application will be then used for her research in the area of test automation and then as a base for writing the research paper.

I am glad that I accepted to do this because by doing the mentoring I get to teach computer science to a hopefully future fellow female developer but I have also the opportunity to refresh my knowledge and I hope that I will learn some new things as well.


I am currently watching 30 Rock, just finished season 4, and Damages, started season 2 last night.

I started reading The Count Of Monte Cristo two weeks ago but I had no time in the last few weeks. I would like to continue reading it but I also bought the Divergent Trilogy too after watching the movie (yes, three books!) and I have some more books lined up since months so I better get to it!

For now I will enjoy the Friday evening and just relax, hopefully have a good night sleep and recover from the jetlag. I made no plans for thecweekend yet although I would like to get some things done but I will just take each day as it comes.

I wish you a nice weekend and lots of sunshine!


I arrived on Sunday evening from San Francisco and after 15 hours of flying and around 26 hours of staying awake I finally slept for 12 hours straight from Sunday midnight til Monday noon. I had to literally force myself to get out from bed otherwise I would’ve slept whole day too.

I took vacation for Monday because I expected that I not be able to function at all but as strange as it may seem I was fully active whole day, I even went to the city center to do some errands. Monday night was unfortunately terrible, I couldn’t fall asleep till 3 am, the alarm woke me up at 8 am because I had to go to work on Tuesday.

I pretty much felt like a zombie whole day on Tuesday although I managed to get a lot of things done at the office, except for the part where I messed up some meeting schedules and got to the meeting room 30 minutes early fully convinced that I am on time so that I confused my colleagues completely but they were luckily very understanding about the situation and we did the meeting earlier than planned.

Around 18 o’clock I started to feel more energetic since that was morning time in San Francisco so I used this time for more productive things but then eventually went home and instantly fell asleep at 8 pm and woke up only next day at 8 am.

Wednesday was great, I felt so fresh whole day and was very productive but then I couldn’t fall asleep again till late in the night so today I am having again another difficult day. I even managed to miss my train stop on the way to work today so I had to get out at the next stop and wait for 20 minutes for the next train so that I can go back one station.

It’s interesting that my nights are alternating between deep sleep for 12 hours or sleepless nights tossing and turning in bed. I manage my work and social life quite well even during this period (if I don’t count that I haven’t been to the gym since almost 2 weeks, I plan to go in the weekend! Scout’s honor!) but I really hope that this will normalize soon. Until then I have my currently favorite TV series 30 Rock and Damages to keep me entertained.
