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 wrangling. I use quarto documents. Before positron

It is sort of tautological: # variable A has three causes: C1,C2,C3 C1 <- rnorm(100) C2 <- rnorm(100) C3 <- rnorm(100) A <- ifelse(C1 + C2 + C3 > 1, 1, 0) cor(A, C1) cor(A, C2) cor(A, C3)

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 would occur it had recorded the last several instructio

I never considered leaving my IBM Field Engineering job. The job was rewarding and gave me a great sense of purpose; however it was very stressful and had a lot of high expectations. With the 360 line of computers the field was flooded wit

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 lot of maintenance. THANKFULLY it was not around very long.

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 of parts and would send them to me via taxi if needed. The

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 number one priority was the bottom line.

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 the display of the electronic signals while you looked for a

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 had not taken over at that time. IBM had a very good support

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 understood the microcode much better. grandfather

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 problems rather than start over. grandfather

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. IBM core units did not have spare positions. Sometime the

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

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. Spoiler is that development is paused, not sure if anyone has cont

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 the website might look pretty terrible without it): https:&

I believe it is rs201731543 Found it by going to the list of all alleles of that gene ( https://ensembl.org/Homo_sapiens/Transcript/Variation_Transc... ) and looking for one that changes the 3444th amino acid from a

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 dependency / minor refactoring https://git

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 different response rates or could even have different reasons for n

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 28." The untestable assumption

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 admittedly I don't look at stock prices very ofte

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 melodic lines with wide intervalic leaps, it's a good option

Lots of people have their favorite cheap electric guitar, but mine is definitely the Tagima TW-55 (not the woodstock series, has to be TW). Can often find it used for ~$180

Totally agree, I think regular tunings are cool and easier for learning in a lot of ways, but the ergonomics of standard tuning or other non-regular tunings make somethings easy that are really beautiful. I think making whatever you conside

Totally, my mistake. The correct term is regular tunings, which yield an isomorphic layout on the guitar (well, it would if you had infinite strings). In plain english, the same shape always corresponds to the same intervals no matter what

by elsherbini 4y ago
I've experimented a lot with different isomorphic tunings on the guitar - that is where each string is in the same interval. The obvious one to try is perfect 4ths, E A D G C F. This one is great because the same shape works everywhere
