On the flight to San Diego I did some Unity refresher reading and some thinking about game ideas that might be worth playing with.
I was looking for references to ScriptableObjects in the books I’ve got and didn’t find them. Guessing the focus there is too new to show up. I’ll post a bit on the ideas front over on PandaMallet in a bit.
It has been a slow summer on the home technical front and I really want to get that stuff rolling again as we move into fall. Plenty of interesting stuff to do, just need to find the time and decide to focus.
…and so far, with the fan blowing on it and keeping the temperature down it seems to be doing better than it was yesterday.
It will be good to have a fallback machine available but I’m really hoping that this resolves the issue.
I do intend to keep a fan blowing across this ‘fanless’ machine as well once I get things back together. Crossing my fingers that this stays up now…
I had a short conversation yesterday about securing UDP data. When I dug around little it became clear that there is an existing, RFC documented protocol for handling that. I haven’t yet read the specification (though I likely will as it is an interesting technology).
There is a wikipedia description here and the primary RFC is here.
Being able to secure unsequenced and unreliable datagram traffic using a design that is reasonably well vetted seems extremely useful. There are places where UDP is uniquely useful and security is becoming a much larger issue in the market today.
Interesting looking sample code here.
Today has wrapped up with repeated DNS failures from my PFSense boundary router. I’ve been trying to diagnose things for a good chunk of the evening and so far have little to show for it.
I’ve played with the DNS configuration and things don’t seem to have gotten better. I’ve got a fan blowing on it…temperature is down but it is still flaking. I’ve reseated the memory and SSD and so far it hasn’t failed again, but I’m still concerned.
I did finally order another similar small machine to act as either a replacement or a spare. The household firewall is one of those things that will really impact everyone here should it go down for a period of days (hours is bad enough) so the spare will be welcome.
Hoping to figure this out in more detail sometime soon. I am expecting to have an external fan blowing across the ‘fanless’ computer from now on to keep the temperature down and hopefully forestall any future problems. It had been getting warmer than I liked, but not so warm that I felt there was likely to be an issue…more to come as I work through this over the coming weekend…
I’ve done some development in an agile/scrum environment. There are a number of things it brings to the table that I see improving code quality in some ways and providing a more stable delivery schedule.
With all that being said, I don’t believe it is a silver bullet and I become a bit annoyed when I read books and articles that present it that way. I’ve been doing some refresher reading lately as we’re working with customers who run agile teams here and I’d like to help our team adopt useful bits of agile without harming our overall effectiveness. This is particularly challenging in a regulated environment like the medical device development we do here. It is also challenging when we’re doing contract development engineering and customers expect to have a contract that covers the work we’ll do before they start paying.
I’ve been running some sort of daily stand-up long before I heard of agile or scrum. If anything, scrum environments seem to make stand-up longer and more formal. In lead roles before I hit scrum environments, my stand-up usually involved going to wherever the bulk of the team was located (if I wasn’t already there…jobs varied) and having a short discussion with members of the team about how things were going.
One aspect of stand-up that I don’t endorse is the ‘blockers’ question that usually seems to be a rote part of the process. In a team of under ten people, there should never be blocking issues that last for more than a very short time. If you know who can help you then just ask (by email if they’re not immediately present). If you don’t know who to ask then either ask your lead or ask someone else and follow it up from there. If someone consistently fails to help those who need assistance then the team needs to stage an intervention and make it clear that we work as a team.
Blocking issues should never persist for long enough to make it to stand-up.
I also tend to use stand-up as a platform to address team wide issues and support issues that people encounter. Another side-effect of the ‘keep it short’ philosophy of scrum stand-ups are ‘information free’ comments. Telling the team that you’ve closed issues/stories ‘1123 and 1127’ and are starting work on ‘1134’ doesn’t really help to share information with the team. It may help the leadership track progress, but they have plenty of tools to do that already if you’re using any sort of software to manage work-flow.
I think this is enough for one day…I’ll add comments in another page in the near future…

I have now received my pi4 board (4 GB model to act as a developer machine for my older pi boards). So far so good…I’ve loaded up the latest raspian (buster) on the a 64 GB micro SD card and things came up just fine.
I’ve got it in a simple case with laser cut sides and a small fan to keep the chip cool…sinks installed on the CPU, memory and one other part. A friend got his board in a bit earlier and loaded it up without a fan on things and noted that the CPU became VERY warm. Looks to me as if this board is going to need active cooling in many cases…I expect this may keep the pi3 in service for some time as a low-power option for many builds.
I’ve only started loading up development related items…went to bed a bit early last night with apt installing emacs when I went to bed. I’ll likely get this much further along over the weekend and post a bit more detailing my experience with the board.
I am hoping to get an OS loaded on one of my USB3 SSD drives as well. This should be faster, bigger and more robust than the micro-SD for the sort of things I’ll likely be doing with this board. I’ll detail my experiences as I get there.
