| daftykins | hoo-hoo i'm a kid at Christmas, arrived in Exeter - at my pal's house on fancy fibre, and many toys to unpack and dabble with | 10:45 |
|---|---|---|
| penguin42 | ah, Essex has dried out then? | 10:57 |
| daftykins | the other E - Exeter - but nope soaking right now! | 10:57 |
| penguin42 | ah | 11:00 |
| daftykins | glad i made it in when i did | 11:01 |
| zxmpi | fibre will do that to you :-P | 12:06 |
| daftykins | wow ETB Tech include a tube of cookies, very nice touch! | 12:10 |
| daftykins | munch + config could be a good combo | 12:10 |
| zxmpi | what type of cookies? | 12:32 |
| daftykins | can't look right now, enjoying the kit! | 12:33 |
| penguin42 | daftykins: what toys have you got then? | 13:05 |
| daftykins | a Dell R6515, with an AMD EPYC gen3 7313 3GHz 16 core CPU, 512 GB RAM, a pair of 1.2 TB SAS 12Gb HDDs and 4 x 960 GB SAS SSDs | 13:12 |
| daftykins | new 24 port switch | 13:12 |
| daftykins | and for the old sandybridge era Dell R820 server that's our current workhorse, 256 GB RAM... 2 ivybridge CPUs that bump the clock speeds a bit and an air baffle so i can remove the daughterboard which houses CPUs 3 and 4 | 13:13 |
| daftykins | 4 socket machine which i'm reducing to a 2 socket since we need single-thread performance not multi | 13:13 |
| daftykins | lots to do! | 13:13 |
| penguin42 | I suspect you'll find that EPYC will kick your ivybridges into this century! | 13:24 |
| daftykins | ooh yes | 13:25 |
| daftykins | the staff's compute will gain a VM atop this hardware but also have a fallback on the old, so i chose to maximise efficiency | 13:25 |
| zxmpi | 512gb of ram... and me here looking at a z80 system with maybe 128-256k :-) | 14:16 |
| daftykins | :) | 14:16 |
| zxmpi | when did it all go wrong :-) | 14:20 |
| daftykins | i know, it's those pesky devs! | 14:21 |
| daftykins | heh, but nah with this one it's that data analysis biz of my pal's where the staff's single scripts can hit 50 GB mem usage mid-run | 14:21 |
| daftykins | i only specified half the DIMM slot count as well, so we could upgrade to 1TB RAM if the need ever arose | 14:22 |
| zxmpi | was listening to floppy days podcast yesterday with interview with guy who wrote sinclair basic. at uni when he started the old mainframe took 20 mins to run a program. they replaced it with better system. | 14:22 |
| zxmpi | within 3 months the twice as fast system was taking 20 minutes to run programs as devs got lazy | 14:22 |
| daftykins | haha | 14:23 |
| zxmpi | he said things have not gotten better since. | 14:23 |
| zxmpi | this is the guy who crammed basic into 4k rom :-) | 14:23 |
| daftykins | amazing | 14:23 |
| zxmpi | orignal version was 5k but had to be cut to fit 4k | 14:24 |
| zxmpi | didn't even have the hardware to test it on | 14:24 |
| daftykins | my pal and his colleague who have experience with RStudio had to have chats with their employees to educate them on the need for efficient script writing | 14:24 |
| daftykins | any ideas what format they were developing on? paper, older system, etc? | 14:24 |
| zxmpi | oooooh, he mentioned so many different systems he was developing on i can't remember. | 14:25 |
| zxmpi | not paper | 14:25 |
| zxmpi | but as someone mentioned later, you could write it down on 1 sheet of paper and debug it there at 4k :-) | 14:26 |
| daftykins | heh | 14:31 |
| zxmpi | https://floppydays.libsyn.com/floppy-days-85-interview-with-john-grant-developer-of-zx80-os-basic | 14:32 |
| zxmpi | at 18m. 8" floppy based zilog test box. | 14:35 |
