I switched to Positron a few months ago and have mostly found it seamless. I'm an academic bioinformatician/data scientist and I mostly use R to do my data visualization and table …

It is sort of tautological: # variable A has three causes: C1,C2,C3 C1 1, 1, 0) cor(A, C1) cor(A, C2) cor(A, C3) # If we set the values of A ourselves... A

I think my most challenging diagnostic problem was a channel hanging the system. I used a 360 I/O channel test box that connected to the channel and when a error or hang condition …

Every form of memory storage I was exposed to worked well except for the delay line storage unit in the controller for 2260 CRTs. IT WAS VERY TEMPERATURE SENSITIVE and required a l…

I was in a resident territory 60 miles from the home office and we stocked a good supply of parts but far from any part you would ever need. My branch office stocked a higher level…

I do not know about IBM today but during my time working for the company they were the greatest company to work for if business was good but in bad times for the company their numb…

I have no idea where computing will be in 60 years. The tool I miss most is the oscilloscope. It was great fun and satisfaction to set up the scope and computer and be able to see …

I do not remember people being concerned about computers replacing them because in the 60s and 70s computers were creating a lot more jobs than they were replacing and automation h…

I did not work on the computers you referred to and my favorite computer was the 360 model 40 (2040) because it was very reliable and relatively easy to work on because by then I u…

I was a hardware tech and we installed updates or patches to the computer micro code many times without replacing the entire code. I think most programmers preferred to fix the pro…

I do not remember any transistors being inside the core house but sometimes the welds inside the house would break loose and if you could find the broken weld you could resolder it…

Hacking was not a problem in the early days of computing as there was no internet and computers talked to each other over dedicated telephone lines. - Grandfather

Hi HN, I’m visiting my grandfather for the holidays. He worked for IBM starting in 1966 as a repairman in Alabama servicing everything from IBM 407/403 “grey iron” to 1401s, 360s, …

This playlist[0] from TangoTek shows him developing a mod to improve villagers in minecraft. Definitely nothing compared to DF, but still much more interesting than vanilla. Spoile…

I noticed one of the captions mentioned it was a Kodachrome slide, and I found this website which has old photos and searched for Kodachrome slides (note I have ublock on, I think …

A year or so ago I found an incredibly well made website that showed isochronic areas from a given address. Now - there are several of these types of websites, most are terrible, b…

I learned about your library because the harmopark.app site uses and credits it. I plan to use it in a music app I'm developing. I saw someone forked it and removed the lodash depe…

As an example, maybe you want to know if freshmen from different dorms had more or less satisfaction that average, but wanted to deal with the fact that different dorms had differe…

That was a good read for me - someone who has heard of Mastondon and ActivityPub but hasn't really grokked the tech and definitely didn't know other alternatives.

(I'm not GP) My answer would be that it's the difference between "Why do mosquitos have differential attractions to humans" vs "Why do mosquitos like Subject 33 more than Subject 2…

Both are down ~10% in the last 5 days, but Uber is down almost 50% YTD and DoorDash is down more than 60% YTD. Looking at the longer trend, it doesn't look like a plunge to me, but…

Yeah, perfect 5ths, or the weird in-between which would be tritone tuning allow for really wide intervalic leaps really ergonomically. Since a lot of progressive music favors melod…
