When I read about hardware modifications of unextendable home-targetted routers, I thought, nerds! On the other hand, doubling RAM memory size for pennies, is attractive perspective for anyone, who plans switch firmware to embedded linux and host services far beyond than typical network functionality. At that time I already had cheap amateur PT-936 soldering station, just for simple repairs. To replace memory chip however, SMT element must be… Continue reading
While reviewing ownCloud features, to get better view on its pros and cons, I realized that sharing feature has one serious drawback. To share a file or a folder you hover over it, click “share” and configure all details. The issue is that there is no single view of all shares, if you forget what actually you are sharing you need to browse through hierarchy of folders and check their status one by one. To solve this problem I made… Continue reading
Days of my old HTC Desire are counted. Despite optimized custom firmware it runs too slow in critical situations leading to missed shots due to laggy camera, waiting long seconds to open apps, constant jitter when company bloatware (read: lotus mobile) is synchronizing, just a few to mention. Swapping HTC Desire for Samsung Galaxy S2 would be optimal choice, the latter still has best hardware-to-price ratio. Is it a good choice for Sense lover,… Continue reading
After disappointing first day, remaining part of my staying was more graceful, once or two times a day showers, humid and hot hazy weather for most of the time. Few evenings free of work and half of next weekend I could dedicate to see what is going on in this state-city. Eating and shopping, this is what Singapore is famous of. These days shopping is no more attractive as it was 10-15 years ago when European prices for electronics were way too… Continue reading
Skating gives a lot of fun. When mastered enough, it is like flying few centimeters over the pavements. To make this feeling persistent, I am going to tell you my secrets of perfect wheels’ rolling. I was inspired by the rain that catched me recently while I was riding through the city, covering my boots with wet sand and mud. I am also inspired by situations I recall, when you could hear a skater, who was making whooshing and squealing… Continue reading
Boundary Event is core concept of UI technology in IBM BPM: any visual element (coach view) of screen (coach) can fire such event moving control from current screen to some other place, crossing “screen boundary“. In fact Boundary Event is the only way to make such transition on diagram of coaches. Problem is that IBM BPM event model is trivial and does not allow virtually any interference with event in progress, one… Continue reading
For prototype I estimated that 128kB or flash would suffice and I was right; firmware took 75kB even though fatten up by embedded strings used across the code for tracing. On the other hand 4kB RAM of Atmega128 turned to be almost insufficient: I had to tune stack sizes of tasks with ten-bytes precision. Tests were running for weaks without problem, yet extra function added in chain of calls could potentially corrupt memory. I had to make more… Continue reading
