Mozilla’s recent blog posts explicitly highlight that they are investing in ads for short-term revenue growth. So when they go on to remove the ToS statement about not selling user data, that suggests to me that their strategy is in fact to collect and sell user data.

Perhaps they aren’t doing that yet, but signs are pointing in that direction. So that does make me reluctant to share any data with them.

It’s like Moore’s law. The number of bytes for a basic app doubles every 2.5 years.

When I was young, we’d get a few different games games on a single 1.4 Mb floppy disk. The games were simpler, sure, but exactly the same games now would be far bigger in bytes.

The Orange Box 2; featuring Half Life 3, Team Fortress 3, and Portal 3.

OpenTTD is a good game.

My computer has a problem where occasionally it will become completely unresponsive. (Mouse cursor doesn’t move. Keys have no apparently effect. Whatever app is running freezes. I think its a hardware problem with the graphics card, but I don’t know what. Logs at the time it freezes say “the GPU has fallen off the bus”.)

Anyway… I recently learnt about Magic SysRq. And I’ve been able to shutdown the computer from this unresponsive state with SysRq, R E I S U O. Where as I understand it, the “E” tells processes the end nicely if they can; and then the “I” just ends them by force.

(At this point, I’m realising that the E is SIGTERM, not SIGINT - so that screws up the relevance of my story; but I figure I’ll keep going anyway.)

The point is, I’ve been using key combo with a nice pause between each key, thinking there was some chance that processes might be ending gracefully. But when I tried it while the computer wasn’t frozen, the computer was able to inform me that the E and I commands were disabled. (I don’t know why.) So even though I wanted to give a nice “please end” signal, in the end that just wasn’t happening.

I’ve been happily using RSS feeds for many years. I mostly use them for webcomics. I’ve got a bunch of different webcomic feeds. But I also use RSS to follow a bunch of low-traffic sites that I care about the content of but don’t want to have to manually visit just to see if there’s an update.

Also, I don’t have a google account, but I use RSS to follow a couple of youTube channels that I find interesting. (Again, stuff that rarely updates. eg. hbomberguy.)

I’ve found that a lot of blogs do have RSS feeds even if there is no visible link or mention of RSS anywhere on the website. I often just throw the blog URL into the ‘add feed’ box on The Old Reader, and it turns out there is feed info hidden in there somewhere.

Using full names like that might be fine for explaining a physical rule, or stating the final result of some calculation - but it certainly would be cumbersome and difficult for actually carrying out the calculations. In many cases we already fill pages with algebra showing how things can be related and rearranged to arrive at new results. That kind of work would be intractable with full word names for the variables, partially because you’d be constantly spilling off the end of the page trying to write the steps; but also because having all that stuff would actually obfuscate what you are trying to do - which is algebra. And during that process, the meanings and values of the pronumerals is not as important has how they interact with each other. So the names are just a distraction.

For setting up an equation, and for stating the final result, the meanings of the variables are very important; but during the process of manipulating the equations to get the result you want the meanings of the letters are often ignored. You only need to know that it is something that can be multiplied, or inverted, or subtracted, or whatever. Eg. suppose I want to rearrange to get the velocity. I don’t care that I’m dividing both sides by the air density times the drag coefficient and the area… I’m just dividing ρCA, which is an algebraic blob whose interpretation can be saved for some other time.

In many ways, the silky-smooth convenience offered by modern computer software makes everything much harder to learn about and understand. For anyone that used zip files before this Windows feature, the problem is obvious - but for younger people it’s not obvious at all. Heck, a lot of people can’t even tell whether or not a file is locally on their computer - let alone whether it is compressed in some other file.

I guess its just a reminder that getting a PhD is often more about dedication than it is about practical knowledge.

I saw someone post this a few days ago, and someone else quickly pointed out that it is incorrect. This time I’ll point out it is incorrect.

In base-pi, pi would be represented as 10. The place value of the right-most digit would be pi^0, and the next digit is pi^1.

Hey, no one is trying to stop you from doing that. I’m sure it is very convenient for you.

My point of view though is that automatically uploading my personal files to some corporation computer on the other side of the world should not be the default when I try to save something. Maybe sometimes I’ll want to use that feature, but there are a variety of reasons why I don’t want it most of the time. And I definitely don’t like having to jump through hoops just to avoid it.

There’s a cool computer game that makes this point as part of the story line… I’d recommend it, but I can’t recommend it in this context without it being a spoiler!

I do.

I’ve got a piece of black tape over the power line on my computer, because it is too bright. And I have masking tape over the caps/num/scroll-lock lights on my keyboard; because they are also too bright. (The light is much gentler through the masking tape.)

I like the meme - but the identity of the villain hasn’t yet been revealed. I’m sure lots of people are keen to see who’s behind the “Jia Tan” mask.

And so the microkernal vs monolithic kernal debate continues…

Over the years, Microsoft has been quietly taking away control from the users.

There’s been a transition from normal settings that you can do whatever you want with, to “yes / remind me later” settings that Microsoft uses to badger you until you submit, to finally just no setting at all - just quiet compulsory data collection and surveillance; with various bits of mysterious software that you can’t uninstall or disable or halt - because you’re not the admin - Microsoft is.

It wasn’t always this way.

Yeah, it’s a minor annoyance… another minor annoyance on top of all the others. And another personal data leak (or siphon) to go with all the others.

This on its own is not worth switching OSs for - but as a piece of a larger picture it’s yet another reason to consider it. And for some people this may be what tips the scales in their evaluation.

I’m sure its different now from when I started - because coding is very popular, and the internet is a thing… But I can tell you, that it took a long time before I knew what a programming language was, or ‘coding’… these words were just not familiar to me.

I learnt stuff by just opening random executable files in notepad to see what they look like… mostly it was just garbage that no one can understand - but some of them were readable, and I replicated and learnt from them. (they were .bat files.) I became a bit of an expert in making very fancy batch files. I made customisable menus, and a little adventure game. Then my parents helped me out by buying me a programming book. It was about programming in Visual C++. I was pretty excited - until I quickly worked out that Visual C++ was something you had to buy before you could use it.

Anyway, my point is that it is easy to see what you need from the point of view of an expert; but from the point of view of a novice, you don’t know what you don’t know. You don’t know which words are important, or what anything is called. The first steps are not hard except that you don’t know which direction you are meant to be stepping in, or where the starting point should be.
