I think the idea is that you use registers and apply the NOR gate multiple times. In this sense the NOR gate is universal, while an OR gate nor a XOR gate are neither universal. I.e. XOR(x,y) = NOR(0, NOR(NOR(x,y), NOR(NOR(x,0),NOR(y,0

Yes, I had the same confusion. There seems to be a standard for TCP over UDP [1]. But in general, I would assume that it does not help at all WRT any of the packet loss/latency problems posed by satellite links. TCP is designed for

I'm running Firefox, installed from upstream, running on Devuan Beowulf. With the default "Courier New,Fixed" font family set it's just not working.

In Firefox (v82) the text-field does not seem to render in a strictly non-proportional font. Thus everything is garbled. Unfortunately w3m text-mode browser isn't capable to display the page... [EDIT] The following steps fix playback

You can very likely compress the table and/or interpolate between entries. It's not like that those entries are totally random.

Using Tcl exceptions, I guess it would be pretty trivial to do that. Here [1] is an alternative do..while loop implementation provided by Tcllib, written in pure Tcl. [1] https://core.tcl-lang.org/tcllib/artifact/4

Well, you don't need 'expr' in contexts were an expression is expected, e.g. 'if' 'while', 'for' (2nd arg).

I have the exact opposite experience WRT Tcl channels when compared to other languages. Handling binary data is pretty trivial, e.g. to read a full binary file into a binary string, you do: set h [open "filename.bin" r] fcon

Good question. I'd pick one of: (a) Smart pointers + static analysis + sanitizers make C++ pretty usable (b) C++ usability requires brittle, half-baked add-ons such as smart pointers and non-deterministic/heuristic/unreliabl

Uh, you're too optimistic: Everybody and their uncle had a lot of ideas about how they would fix "C++". Eventually all those contradicting ideas got merged into the C++ standard. :)

I think for shared_from_this() I have a different use-case in mind: an object of some class wants to register with some other class. I.e. think about something like auto self = shared_from_this(); document.onclick([self](){self-&gt

by dvdkhlng 6y ago
When I think about C++ "smart" pointers, I often think about easy to provoke / difficult to spot fatal edge cases. E.g. - C++ code where some method calls std::shared_from_this(), and that method ends up being called indirec

I can second that, I have seen people frustrated after loosing work in Snap! by missing to save. But then that's maybe also a lesson people ought to learn early-on when creating stuff on the computer: safe early and create backups :)

I'd suggest TIC-80 [1] as an intermediate step from Snap! to larger IDEs. TIC-80 documentation [2] is a little thin, but overall it's a very pragmatic integrated development environment that combines sound, sprite, map and code-e

From my experience, as a cyclist speed and acceleration helps with avoiding car-related danger. If you're fast enough, cars won't needlessly overtake you (in rush hour, most car traffic may not exeed 30 km/h for example due

In case people don't get the "white spray painted biycles" reference, see [1]. Berlin just got 15 more of those bikes this year already (which is more than usual, maybe due to corona). [1] https://en.wikipedia.org&

by dvdkhlng 6y ago
The problem with this is that car drivers usually just assume that the cyclists could just safely use the bike lane, while in reality many bike-lanes are statistically more dangerous than just driving on the road. In Germany there used to b

You mean that IPCC predictions based on climate models have been replaced by different predictions based on newer models as more data became available over time? Unfortunately (for us) it does look like newer predictions predict worse outco
