Well...it gets the point across lol

Use the Apollo computer to mine bitcoin? Technically yes but at 1 hash every 10 seconds, no. Fascinating coverage of how to develop for it though! #retrocomputing #space

The conclusion nicely puts the power of the AGC into its period context. Not a bad machine for its day given that they required it to be small light and rad-hardened.

@Stephen Gunnell Yeah as they said it was relatively underpowered at 40K add operations per second compared to other computers of the day but other computers of the day were also far more massive. It's pretty amazing how well it performed against microcomputers 10-15 years later. I found this article on benchmarks from 1977. Looking at the integer add test Microsoft's BASIC took 10 seconds to do 1000 additions. At 40 KIPS the AGC would have done it in 0.0125 seconds. If we say that the comparison took up as much time as the addition and the BASIC interpreter is 10x slower than the same routine written in assembly language then we'd still be looking at the AGC being 10x faster. This makes me want to rerun these benchmarks and write them in 6502 Assembly as a comparison lol.



 



 
Another interesting article on replacing modern IEEE floating point with newer approaches that get rid of some of the nasty artifacts we constantly deal with while simultaneously reducing memory/storage requirements #programming #hpc

Brad Koehn ☑️ reshared this.

It is interesting that he is still touting as a positive benefit what I have seen other people pointing out as a distinct failing, the merging of +/-0 and +/- infinity.



 
I have seen reports on the nature of the errors (basically computer was asked to compute more than it had capacity for) but not the why or the fail-over modes if the condition persisted. Great article #space #retrocomputing

But is he winning?

Hope he's got a poker face

Programming langues I've developed in the last 7 days: C#, Java, FORTRAN, C, Forth, Kotlin, Ruby, Objective-C. All but Forth for actual projects. #polyglot #programming
#polyglot #programming programming

That's an incredible achievement. It's more than one different language each day! 😉 😆

Yeah it comes from needing a combo for some projects. Like the Java, FORTRAN, and C were two parts of code bases for the same project. The Kotlin and Ruby were from polishing up the Diaspora API Client I wrote (Kotlin) waiting for the hopfully imminent release of 0.8.0.0 (Ruby) but had to fumble around in there to see where and why something changed so I could update my client.

I've got a long list over lifetime, but in last week or so at work? Go, VB.Net, DOS Batch, Bash, T-SQL, and Java - and the barest touch of Kotlin.





 
Got my Diaspora API #kotlin client libs working against the latest API branch code. Ready to run against server with API code #diaspora #diaspora-dev #fediverse https://www.nequalsonelifestyle.com/2019/07/04/getting-ready-for-disapora-api/



 
In an exchange with a friend about my FORTRAN post a joke was made about exploring Forth for the Fourth. Actually that sounds like a neat little #programming experiment so here we are...lol... https://repl.it/languages/Forth

We have #fediverse platforms already in production and still under active development to replace traditional social media. Who do Sanger and TBL think we need something brand new? What's this boycott PR thing to boot? Help make the fediverse viable guys!

I have signed it.
