My request for base DHCP Client options parsing was partially implemented.

If you happen to work on OSX with MacPorts and GPGTools using SmartCard for SSH then installing OpenSC (0.16.0 in my case) will break your smart card access for GPG/SSH. If you remove OpenSC with an uninstall utility things get back to normal.

It is my pleasure to be part of organizing committee and scientific board of this cyclic international conference on Telemedicine and eHealth arranged by Polish Telemedicine and eHealth Society. You can click image below to see the full conference program.





Today is my last day with HBO in Poland. I could not even imagine how bad can commercial mobile application be until I found HBO GO PL Android. This is such FAIL that I am not going to pay anymore for this crap. I have waited over a year for things to get better. I bet most of the 5 star ratings are fake. You don’t give a shit about user feedback, so users will to the same with you. Goodbye HBO..

On the other hand Netflix has just entered Polish VoD market with a far better application. They responded to my feedback in less than minute and implemented suggested (localization) changes in two days. Now that is good cooperation! Learn from that!

I have just found and reported bug in credit card related form/script in popular Polish trading platform Allegro. This was just a minor compatibility issue.. 😉

I have just reported several issues and ideas related with this nice Google Hangouts Android application:

  • The name Hangouts is not popular and hard to remember. Abandoning “Google Chat” or “Google Talk” was a bad idea. People tend to remember short names and popular words such as “Skype” or “Viber”. This may be funny but people really cannot remember “Hangouts” well.
  • Receiving calls is misleading. There are several different ways to answer an incoming call in Hangouts. Most common way is to press a button and then drag it onto an icon that is not visible until you press a button. Another way is top view pop-up which could have color buttons in addition to small icons. Older people have problem with this. Average non-geek user simply needs Green Answer and Red Reject button.
  • Hangouts would be simpler to use and more popular if it worked just as an ordinary Phone Call application. Non-geek users have this habit already on how to use Phone Call application, that Hangouts should leverage.
  • Hangouts voice/video call should be available directly from a Contact Book if gmail address is present. Just as phone call.
  • There are Android devices that offer hardware phone buttons (such as LG Wine Smart). Green Connect and Red Disconnect buttons should be also available to perform actions in Hangouts.

These simple ideas arised from observing older people trying to use Hangouts to videocall their family members..

It is possible to connect a game controller to Android based device and use it as input for your application [1].

Most modern Android based devices support USB OTG function [1]. USB is a Host centric bus that means there is only one Host device and many different Devices can be connected to it. Using inexpensive USB-OTG cable it is possible to swich smarphone USB port from Device to Host, and connect external devices, if chipset and OS build allows this. Google provides detailed information on how to code USB Host [2] in your application.

As an exercise, I have just designed (using FreeCAD) and 3D-Printed (using semi-translucent PLA material) a casing for M24LR-DISCOVERY (CR95HF NFC Reader). Let me know if you need one :-)
