Thonny is an IDE... (B.Good was addressing an earlier edition of my first post, which was unclear. before I fixed it, his comment made sense, and I answered it with "Understood. Is the interpreter/ compiler invoked when Thonny used in the most novice-likey way unsuitable for the task?") In other ne...

I'm very new to Pi... but old to computers. Once you have things set up right... I can do this bit!... an IpCam can serve an IMAGE to a web browser in response to a command. I use this across my lan to look at what different cameras are seeing at the moment. When you fetch a page this way, you don't...

Wow! THAT brought back memories!! I am a long-time fan of Pascal... going back to the days of Turbo Pascal in the early 1990s... late 1980s? Anyway.... I hope the following will shed light on the discussion above. Most of what I'm going to say was mentioned at some point, but I hope the following wi...

9 Aug 2018... a simple... sudo apt-get update sudo apt-get upgrade sudo apt-get install fpc sudo apt-get install lazarus ... was all I needed to get a usable Lazarus 1.6.2 up and running on my RPi 3 b, with 16G SD card, Raspbian 9. An entry to launch Lazarus just appeared in the Programming category...

k-pi... very helpful...thank you. I hadn't known how to find out what groups pi was part of. And the article very clear, very helpful. Your encouragement gave me the energy to struggle on. First I found http://www.auctoris.co.uk/2012/07/19/gpio-with-sysfs-on-a-raspberry-pi/ ... a good discussion of ...

I think I have a "permissions" issue. I created a new user... I didn't want to do everything in user pi, that being an intruder's first port of call. My "alternate user" will be, I hope, as powerful, mostly, so LIMITED protection, I know. But maybe "a hassle too far" for the intruder. I then install...

(new material added to this post, 7 Aug 2018, 3pm New York time) One way to get a "static" IP is to configure it in your router/DHCP server. You can usually associate the interface's MAC address with a particular IP address and then you don't have to change anything on the Pi. I think my router prov...

Sheepdog

Thank you, bgrundy and others. The router is marked "Motorola Surfboard SBG6580. The interface, via 192.168.0.1 says "Arris SBG6580" The wonderful Google managed to find the right document even though I missed out the S. Search string BG6580 forward by MAC address https://arris.secure.force.com/cons...

Thank you... and all you say makes sense. (Apart from one nit I will pick.) However, I DO want to run a server that will be visible across the interent... hence my caution. (And I still find the fact that one can change the user pi password with the GUI without knowing the old password poor design.)...

Sheepdog

Thank you, rpdom... and thank you Arris/Motorola for a good router, with good documentation both in item and online. It seemed like such a good answer!!! (Never solve something, when you can go around it!) But. MY router's "pass through by MAC address" feature doesn't allow binding to a LAN IP addr....

Thank you, grk... For others reading this, I think the guide he meant is... https://www.raspberrypi.org/documentation/configuration/security.md ... which is good. Nice to have support for my uncomfortable feeling that using sudo is too easy... thank you. The article shows how the operation of sudo c...

Newbie here. Environment stated in signature... I THINK I "need" my Pi to use a static IP. I am building a web-server in a home environment. It will be on my LAN, accessible to WAN via the magics of NAT and DYNDNS. Without a static IP, how does NAT know where to redirect incoming packets for the por...

Sheepdog

Yes, I'm an idiot. No, I am not a completely inexperienced idiot. I'm new to Pi, but want to set one up as a webserver, open to "the world". It won't be my first Apache server, but a long shot. But will be my first Linux Apache server. I want to be "secure". I was wondering if it would be a good ide...

New to Pi and Linux generally... old to computers. 4 Aug 2018 I put Raspbian 9 (Stretch) on a Pi 3 B (ver 1.2), and did apt update, apt upgrade. In the GUI, I can change "the" password... without having to authenticate myself with the OLD password. Seems a bit of "back-door" for bad guys! (At no sta...

Not a question... a report of "how to", I hope. Maybe spare the next person. Inspire the programmers. HOURS spent by me, new to Pi, old to computers today. Wonderful experiences initially... then tried to connect my Pi 3 B, ver 1.2 to my Wi-Fi. (Yes, did sudo apt update, upgrade... about 1pm New Yor...

I've done 1-Wire on a Windows machine, using Lazarus and the Dallas TMEX SDK... http://sheepdogguides.com/lut/dstl2hello_ds18b20.htm I know others did work for many years on Linux + Delphi, and Lazarus is "just" a "free Delphi". With PCs, instead of using a bit on a bank of GPIO pins, a lot of the "...
