Sounds pretty good. Does it say anywhere when it will be available? I didn’t see a release date in the article.
I know that header files have some pretty horrible issues with templates and cyclic dependencies and so on, but from an organisational perspective I really like them. If I have to implement some complicated algorithm I could easily have a thousand likes + of Code, but the header still quite nicely shows the general structure in one or two screens. Whenever I do classes in python I start wishing for headers at like 300 lines, simply because I loose track of all the functions I already made.
Maybe I’m just not a good python programmer tho.
I use tiddlywiki for my single-user wiki. The setup is dead simple, one html file on your computer you open directly. There is also a nodejs server implementation, which I use.
Maybe we should talk about what “infinite” means. I’d like to propose the following idea: a sequence of things is infinite, if there is always “one more” object to consider. We could also say that for any number of finite steps, there is always another object of the series we haven’t looked at yet.
As an example, the sequence of natural numbers would satisfy this: if I start considering the sequence 1, 2, 3 and so on, if I ever stop after finite time (say 1729 steps), I can always compute +1 to find another element of the sequence I haven’t seen yet.
Also consider the following: the set of all numbers between 0 and 1 is in some sense bounded. However, I can find an infinite sequence of numbers in this set: consider 1/1, 1/2, 1/3, 1/4, …
These numbers are always between 0 and 1, and are infinitely decreasing.
Perhaps the confusion comes from you talking about infinity as in a number which is larger than any real or natural number, while I’m talking about sizes of sets of infinite size. As I had demonstrated earlier, we can show the existence of uncountable infinite vs countably infinite sets, while such distinctions don’t really come up in limit theory and calculus.
I’m not entirely sure I understand your comment, but the fact that there are more real numbers than natural numbers can be readily shown using something called cantor’s diagonal argument. It goes something like this:
Suppose the set of real numbers and natural numbers had the same size. Then we could write down an infinite list, where each line represents some real number written in it’s decimal representation. So something like
1: 3.14159265
2: 1.41421356
3: 0.24242424
...
This list goes on forever. We will now construct a new real number r as follows: The first number after the decimal point of r shall be different from the first number after the decimal point of the first number in our list, the second shall be different from the second decimal of the second number on the list, and so on (the name diagonal argument comes from this, we consider the entries on the diagonal from top left towards the bottom right).
The key point now is that this constructed real number is different from every single number on the list: After all, we have made sure it differs from each number on the list in at least one place. Therefore, it is impossible to write down the real numbers in such a way that each real number gets its own natural number: There are simply too few natural numbers for this. In particular, there are at least two different “sizes” of infinities.
Pihole reloading in my case is probably mostly slow because of the hardware. That signal functionality to reload is pretty neat, though I think I disagree with the config files being the only thing specifying the servers behaviour exactly being a big advantage. In an environment using infrastructure as code it would probably be better to define DNS over the generic nsupdate API (e.g. with ansible or other equivalent tools) than having to write custom code to reload some config files that have to be regenerated every time. But for smaller home setups both options are probably fine anyhow.
Not that I disagree that NASA isn’t safety conscious, but I’ve recently watched a video about the challenge disaster which seemingly could easily have been avoided if they had listened to the weather concerns or redesigned their solid boosters after issues were observed in the first place. I guess in that case they just got too complacent.
Does this support DNS management with nsupdate? I’m currently automating DNS on pihole by changing a text file and reloading the service, which is just not very convenient not to mention slow.
kobo.com sells books without DRM (under eBook details they tell you the exact format). For example, the murderbot chronicles are sold without. Sadly they don’t have everything like amazon does, especially for niche authors that only publish digitally.
