Dijkstra's algorithm is used in the OSPF routing protocol which used to route traffic around large networks (think ISP internal network, or a large Enterprise).

I wonder if that includes the SFTP server component of openssh? If so it would be very useful for use with rclone. I back up my phone by running an sshd in termux then using rclone with sftp remotely. This works very well (until the phone d

The book makes a lot of things clearer than the film. Interestingly the book and the film were developed together by Kubrick and Clarke as a collaborative process. Usually the book comes before the film, but occasionally it comes after. I c

Debugging with print has one feature that debuggers will never match. You can send the binary or code with print/log statements to someone else who is experiencing the problem and get them to run it. Often I have to debug bugs I can&#x

I used to play conkers at school in England, however my children didn't. The reason? Schools have banned the game of conkers due to health and safety reasons. I asked my 17 year old this morning and he had never even heard of the game

Writing an rclone backend for borg is something I have wanted to do for a long time. However I found that the backends weren't well abstracted enough in v1 to make that easy. However for v2 Thomas Waldmann has made a nice abstracted in

The unique package is my top feature for go1.23. I've been experimenting with it in rclone. People often want to have millions of S3 objects in memory and reducing the memory used would be very desirable. I interned all the strings use

Apart from backwards compatibility, 32 bit apps can use less memory with half size pointers and ints than 64 bit apps.

This is the DNS records expiring rather than the domain. On most providers DNS records are provided for free as part of having other services (eg a VM) so there is no incentive for the provider to nag you about your DNS records expiring. Th

I think the DNS provider is missing some due diligence. What happens is Alice creates some DNS records for example.com which is registered elsewhere. Everything is fine. At some point (maybe Alice forgets to pay the bill) the DNS records ex

That was a great read. All that linker wrangling is sure to break on the next version of go/rust/linker isn't it? I wonder if it would have been easier to disassemble the rust binary and turn it into Go assembly and use that.

Yes, I was thinking this would make a good basis for a Greg Egan story too.

In libgmp I think the numbers have to be around 100,000 bits or 30,000 digits for FFT to be faster. https://gmplib.org/manual/Multiplication-Algorithms GMP has lots of other methods in between schoolbook multiplication

You can use this method to multiply long numbers together. The key insight you need is that polynomial multiplication is the same as normal long number multiplication without doing carrying. So suppose you have a 1000 digit number. You then

I'm not a big fan of auto generated commit logs - they just have too much noise in. You might as well look at the git history. Changelogs should be for users to read. I have a program which generates the first draft of the rclone chang

The main problem the method pointers solves for me is answering the question "can this object do X". The mere existence of a method you can type assert isn't enough. Returning a NotImplemented error isn't a great solutio
