Day 2 of the Embedded World – MES053

Day 2 at the Embedded World 2017This is the 2nd episode of my 2017 visit to the Embedded World exhibition in Nuremberg. For the 1st part please refer to this episode.

I have captured these details on my 2nd day at the Embedded World 2017 in Nuremberg. I once again want to present smaller companies. Of course always with interesting, sometimes even exciting offers. I do not want to ignore the bigger ones, however it’s like looking for nuggets. You have to dig deeper and scrutinize into the inner details. I would be very happy if you find something in for you which is worthwhile to share again. Please do not hesitate and forward this episode to your friends and colleagues.

You are a more visual person? You’d like to see some details? Then look at my day#2 video and  day #1 video at YouTube.

    Dear Georg.

    Thank you for your podcasts. Sounds nice, quite professional and ordered. This one is particularly interesting. I work within Automotive Embedded Systems and Control Engineering domain and will be glad to study new technologies, collaborate/cooperate efficiently towards concrete goals and accomplishments, enhance my current knowledge and skills as well as to acquire new skills.
    The domain is very large and continuous study is essential to be efficient within the field.

    Would you be so kind as to write / explain me if I have a web site which supports only HTTP connections, how can I make it working on HTTPS? How the migration to HTTPS is done usually today?

    Kind Regards,
    Dipl.-Ing. Pavel Mazniker

      Hi Pavel,

      thank you for your comment.

      As you know changing from http to https usually means to introduce an additional encryption layer (TLS/SSL) into the communication between host (http://embeddedsuccess.com) and client. For TLS-connection setup you need to have a certificate. It’s quite easy to create your own host-certificate, but if you do not spend some money (regularly every year) your certificate will not be signed by a Certificate Authority (CA). Every web-browser has public keys of lots of official CA’s built in. If the browser requests a https-connection and gets a host-certificate signed by an official CA, the browser will continue with complaints. If you, due to cost reasons or similar, try to use your own self-signed host-certificate the browsers will yell like hell. And many visitors will avoid visiting the website for that reason.
      Here https://letsencrypt.org/ enters the game. Aka roughly 2 years ago Let’s Encrypt came up to provide host-certificates for no money. These certs are only valid for establishing a TLS/SSL-connection, no signing, no encryption, nothing else. But they are free.
      And many web-service providers (like mine, I do not take the effort to run my own root-server) provide nice interfaces to introduce Let’s Encrypt certificates. Now it should be possible for everybody to use https instead of http.

      That’s fine if you start from scratch. If you already have a WordPress (or other) installation running you need to migrate from http to https. In WordPress there are tons of references to http://embeddedsuccess.com which have to be adapted. All manual work – no automation!

      I followed https://www.webongo.de/wordpress-https-umstellen/ and https://dhue.de/wordpress-blog-von-http-auf-https-umstellen/. Sorry, all of them in German, but in the first you find all of the mandatory SQL-statements to also modify the underlying MySQL-database.

      Migration lasted roughly 1 hour. Hereby taking the full-backup used up half of the time. Preparation time was a bit longer. Needed several hours to find appropriate details, give it a try on a test-domain and make some errors 🙂

      For me the backup was important. I do use Updraft Plus for making my backups. It’s up-to-date, reliable and can also migrate WP-installation from one domain to another.

      How migration from http to https is done nowadays in general I cannot reply. There are too many approaches, installations, web-servers and other impacts. But having a certificate available you should be able to find sufficient resources in the net.
      BTW, have a look at the https-session opening using wireshark. It explains a lot what actually happens between both parties.

      Cheers, Georg

        Thank you Georg for your awesome reply and your valuable explanations.
        1)I think I need step by step guidance how to achieve a particular goal.
        2) Currently I have a project and a great idea, that I plan to continue to work on: Autonomous driving (ABS, ESC, Cruise Control, Advanced Lane Departure Warning, Automated Guidance Vehicle Systems) with high levels (up to 4) of SAE Automation. I will try to make as much by myself. Together with this I think I need help from Automotive / Embedded Systems Engineer/Specialist impassioned within the field. This is to work on regular bases with steadfast commitments. This is to build part by part, module by module a few such systems from concept to implementation, installment and testing. Please if you or somebody around you are interested to join to work with me on this domain, then please connect with me at gmail hangouts: pmazniker@gmail.com or / also via e-mail swdevMPaul@outlook.com. For this project you can work from your place, results submission, integration of modules via internet. When you or somebody, which are interested to work/contribute on this domain contact – you are welcome to contact please put in your letter detailed information, about what are you strong in to do/make/prepare, how do you think to start (from which module), what have you completed before within Automotive Engineering, Electric Vehicles, Vehicle Control Units (Autonomous driving (ABS, ESC, Cruise Control, Advanced Lane Departure Warning, Automated Guidance Vehicle Systems) ). This work is quite serious, I am serious about this work and will respond if concrete examples provided.
        Kind Regards.
