LOOKING AT THE MASTODON SERVER CODE
I’ve spent a few hours over the last couple of nights looking at installing a Mastodon server, and unfortunately it doesn’t seem to be designed to scale, so I can understand why folk are having a rough ride atm. Here are some things I found… Firstly it doesn’t appear to allow for read-replicas databases to be configured during the setup process. Read replicas can take a lot of the load off the more critical (and lock prone) writeable servers, so not having RRs can cause pain as things scale.
TWITTERS LAX SECURITY
If you are wondering if the claims about Twitter security being lax is just one person complaining, you might be interested to know that, 18 months after being let go from the company, I had still not been removed from their employees GitHub committers group. My access was confirmed by a third party, and, during that 18 month period I had access to private repositories as well as the list of Twitter employees who were also part of that group, but had chosen not to make their membership public.
GUESSING THE ANSWER AT WORK AND SCHOOL
I had an interesting, and long, chat with someone who has as much experience with teaching as I have with computers. It focused what seems to be the toughest challenge I find with new grads; Getting them to realise they shouldn’t guess answers and say “I don’t know” instead. We agreed that the many countries schooling systems penalise students for not guessing. If a student says “I don’t know” they will never get a mark for the question.
THE UK "APPLE TAX"
I was tempted by an m2 Mac Air to test the arm64 Apple Silicon emulators we’ve been building at Snapp Automotive. To make sure I was being charged a reasonable price I decided to do a little maths and found out the m2 MBA is 8% more expensive, after taxes and foreign exchange rates, in the UK than in the US. Here’s my calculation; USD MBA Starting Price: US$1199 USD/GBP Converstion Rate: 1.
This Android OS code looks, to me, like it’s been written by folk who absolutely believe Enums don’t have a place in code, but a 300+ line switch/case statement is just fine. Using Enums and .name() would remove the need for that horror. Even using reflection would have been nicer. Scanning the class’s static members and printing the name if there was a match in values would be less cognative load that this beast in my view.
700 MILES IN AN EV
So having spent last week doing a 700+ mile trip across the UK (east to west) with some stop offs, I can now understand why using a Tesla gives folk confidence in an EV-only future. Compared to my Leaf, the Tesla experience is like living in the future. Teslas charging infrastructure is miles ahead of the UK public infrastructure in terms of chargers per site, cars on the road per charge point, and distance between sites given the average range.
WHAT IS "EQUAL PAY" FOR DEVELOPERS
I’ve seen another loop of the “all coders should be paid the same!” discussion. This viewpoint ignores a fundamental factor in deciding pay; The amount of money someone needs to feel it’s worth working for a company, which varies massively depending where the work is performed. Basically all business operate to achieve a task in the most cost effective way. This allows the company to build up cash reserves for unexpected issues or expansion.
WHY STOCK/SHARES ISN'T A SUBSTITUE FOR SALARY
There’s been an increasing trend in Stock/Share Options, RSUs, and employee share purchase schemes, some of which are hyped up to give the impression that they’re worth more than your base salary. While, in some cases, this is true, there are as many examples of where it definitely is not. When you join the companies who use these schemes as part of your compensation package you are usually given a monetary value of shares which gets converted into an actual number of shares around when you get your first pay packet.
ANDROID T DEVELOPER PREVIEW 1 AND THE AOSP
Google recently release Android 13 (T) Developer Preview 1, and, while there are times when a lot of noise is made about Android being “Open Source”, what gets pushed to the Android Open Source Project for developer previews gives us some signals on how this is mostly an afterthought rather than a core part of Androids development. I’ve tried building the Developer Previews of 12 (S) and 13 (T) and both were pretty much unusable.
THE UK EV INFRASTRUCTURE NEEDS A LOT OF WORK
After an attempt to do a 170 mile round trip in my Nissan Leaf, it has now been consigned to a life of “less than 100-mile total distance” trips only. The first leg was fine up until the charge point. The initially selected InstaVolt charger was “temporarily out of service”, and a nearby ChargeYourCar charger was unfathomable to get working as the “Pay by Phone” phone number on the unit wasn’t working.
