It takes me back! I wrote my first one in Z80 assembler a looong time ago as part of my first real job (~1990) which was used to error correct a satellite channel (bandwidth about 19.2 Kbit/s IIRC)! It used lots of table lookups to ma

Go may not be the language with the most features or have the longest academic pedigree but it is really good for getting stuff done. I think that the problems that Google were trying to solve with go are particularly relevant to the open

I think you are talking about bare returns, which are somewhat orthogonal to named return values. You can use non-bare returns with named return values, just mention the names in the return statement. This compiles to the same code as the

This is probably not surprising; given the way they've been treating rclone and its users it is clear that they don't like heavy users. On the plus side (now that they are charging a sustainable amount for it) perhaps they will r

I found a bug in Go which turned into this CVE https://www.cvedetails.com/cve/CVE-2015-8618/ I applied for a bug bounty, but alas was turned down as Go isn't a Google service and it wasn't in scope for t

I had fun playing this game for a while. Eventually I discovered some fairly reliable algorithms which enabled me to collect all the achievements. I'd like some bigger boards to have a go with now!

What fun! I did a similar project in minecraft with my teenaged son a few years ago. We started by designing gates (made of torches and redstone), then a clock, then a divider chain, then a demulitiplexer which drove the 7 digit segments. W

MD5 doesn't seem to be in the table... That is going to make it harder to change code to use multihash then migrate away from MD5 gradually. MD5 may be broken as a crypto hash, but there are probably more MD5 hashes than any of the oth

I believe that fragmentation isn't such a problem in Go programs because they make less use of the heap than Java programs. I can't remember where I read this though. I don't know much about the internals of Java, but I know

That was my thought too - I was taught to do one row of the first matrix with one column of the second matrix at a time. I found the whole staircase thing quite confusing.

The one you linked to is excellent. It has hand crafted SSE3 assembler for enormous speed. It is a bit difficult to compare the benchmarks from the one in the original posting to Klaus's as they aren't done at the same (N,K) par
