Results of the blog survey
One month ago I proposed a survey (Survey about my blog: https://blog.apdu.fr/) to know more about you, the readers of my blog https://blog.apdu.fr/.
I now have 42 answers. I think 42 is a good number.
My survey had 4 open questions. Some of you entered very specific and personal information. I will try to not include personal information in the results. But I am very thankful for your confidence and the details you shared with me.

I am surprised to have so many users of smart cards for such a long time.
Maybe I should have been more explicit in my question. I have been using smart cards myself since around 1990 with French public phone cards and bank cards as a normal user. My question was more, since when do you use smart cards as a professional?.
It is interesting to see very experienced smart card users and also all the possible groups of experiences.

This question has a trap. My blog started in 2000, so the oldest article is 15 years old. It is not possible to read it since more than 16 years.
The distribution of results is fairly even.

With no real surprise, the vast majority of my readers are developers. This is not surprising since the majority of the blog content is about programs and programming interfaces.
In the "other" category, we have:
sysadmin
manufacturer
functional and technical expert
driver packager

Many readers find the articles using a search engine. I guess it's the normal way to find a solution to a problem or some documentation.
I will continue to include references to my blog articles in the emails I send. I find that writing a blog article is a good way to not write again and again the same thing.
Few readers are using the RSS feed (but see RSS feed for my blog).
In the "other" category, we have:
bookmark
redirected by a colleague
Firefox Update Scanner (maybe the RSS feed could be used instead?)

No surprise, with a large part of developers, the main interest is in technical explanations and new software announcements.
I am happy to see that few people are looking for content about Windows issues.
Some people are looking for news about my holidays. That is nice, but I do not plan to share many photos here. Great game contest: Where was the picture below taken?
Free form
Thanks for your answers in the free forms.
What content would you like to find on my blog?
In no specific order:
news about pcsc-lite
more details about PC/SC and Smartcard
-
sample code and technical explanations
Yes, of course.
-
more card specific stuff like reading passport information or discussing a bit about EMV processing
My expertise lies more in PKI cards. I agree that it's interesting to have more details on common cards like EMV, passport or ID cards.
-
chart of specifics/features/bugs between smartcard readers, cards and OS/driver versions
You can find a list of readers you can't use at Disabled CCID readers and readers you should not use at Unsupported or partly supported CCID readers.
I have never seen a really bogus smart card.
-
your history with smart cards
I started in the smart card industry in 1997. At first, it was difficult to use a smart card on a GNU/Linux system. I started by writing a driver for a serial smart card reader, then submitted patches to pcsc-lite and continued developing different smart card related software.
Conclusion
Do not expect posts about my holidays or my life.
I will continue to publish technical articles. If you know about a subject and want to share your knowledge, I am open to co-author articles. If you wrote a Free Software program or library that uses a smart card, I can take a look and write about it.
In any case you can contact me. My e-mail address is available from About me.
