When I look back on the really helpful blog posts I have read, they have all been really basic. Whether they described a programming technique or a recipe for a new meal, it was a clear description that was important - not how esoteric the knowledge was.
There is a place for complex blog posts on arcane subjects but posts on "common knowledge" are even more important. There is a 15 year old out there somewhere that needs to know how to use the different smart pointers in C++ or how to properly care for a cast iron pan.
I think what you are looking for is something like Mastodon or related activity-pub service. You can run your own instance and nobody can take that away from you. No need to drag a blockchain into it - just host whatever services you need.
What is the incentive for an individual to participate in a non-financial blockchain?
Bitcoin-style blockchains “work” because everyone gets the possibility of a little reward for all the hassle and non-negligible CPU time of being a node.
This is pretty neat if all you need is to ping a local server but please use curl (or something equivalent) for contacting remote services. HTTP1.1 seems like such a simple protocol but in the real world you need to deal with proxies, different encodings, and redirects. Curl takes care of that (and a host of other annoying stuff) for you.
Exif is great but here is your obligatory reminder that if you are publishing images you should strip out some of the identifying information that cameras and image editing software likes to embed.
In particular, you probably don’t want the GPS coordinates of your house publicly available on your blog for everyone to see.
My static site generator strips out exif data from images and I would expect all sensible sites would do the same. There is a lot of personal information jammed in there - if you post a picture of your dog making a funny face to social media you don’t want the exact GPS coordinates of your house plastered over the internet.
You have to be selective though, some of the EXIF data specifies things like color spaces and orientation that is used by browsers for displaying the image properly.
These were some of the most influential books of my youth, teaching a generation of young kids quite advanced topics. I still picture cartoon robots putting numbers in boxes whenever I write code involving pointers.
But my favourite[0] was Write Your Own Adventure Programs, which taught data driven programming and text parsing.
IBM was legendarily over-managed. This is second-hand but a guy I used to work with told a story of when he interned for a summer at IBM in London during the mid-90s doing what would now be called a QA engineering. At that time everyone wore suits to work but the culture was changing so the interns put in a request to be allowed casual Fridays. Bear in mind that they were locked in a back room somewhere without any customer interaction so they didn't think it was a big deal.
Months later, just before the end of the internship, they received a reply. Their manager had forwarded their request up the chain of command and the email had the full quoted history. Their request had been bumped up 4 successive layers in the London office, then across to the US headquarters where it continued its upwards trajectory, finally alighting on the desk of a VP who, after thanking them for bring the issue to his attention, rendered an carefully considered opinion.
The whole process had taken weeks, presumably as each person in the hierarchy debated whether they had the authority to tackle such a weighty issue.
The email had then been inexplicably bounced back DOWN the chain one link at a time, back across the Atlantic Ocean, and through the local office, down to the suit-bound interns, again weeks later, who by this stage only had days left at the internship.
Aaronson know his stuff but I am not sure he hasn’t considered the fact that, in this current hype cycle, the quantum researchers breathlessly reporting to him on a breakthrough just around the corner are just lying to him and themselves.
I have been hearing about one more technical hurdle to solve before quantum algorithms become feasible since before I graduated. That was in 1996.
I have been trying for years to get good at 3D modeling with Blender and have also failed. But I didn’t let that stop me using Blender to produce illustrations for my sci-if epic interactive fiction game that ended up being nominated for a minor award for graphics (it didn’t win).
Let me introduce you to the last resort of the struggling artist - extreme stylization. Really good pixel art is a very difficult discipline but terrible pixel art can be just as appealing if you push a style you can call your own.
I haven’t had comments on my blog for over a decade now and I don’t miss them. For every useful and informative comment I got several spammy or rude reply. Anyone who wants to let me know something about my blog can message me on social media.
I’ve seen blogs that do not host comments themselves but instead automatically surface social media (usually mastodon) comments which I think is a useful technique.
