has anyone here used a whole house surge protector before? like this one: https://www.homedepot.com/p/Eaton-Whole-House-Surge-Protector-CHSPT2ULTRA-1/204761136 |

~ 1 hours 31 minutes ~ |

billymg: do nontrivial surges actually happen where you live? |
10:35 |
billymg |
asciilifeform: all my electronics are plugged into either UPS or surge protector strips, and a few fridges and washing machines each have their own one of these |
10:38 |
billymg |
before moving here never heard of surge protecting large appliances. learned about it when a new fridge i bought had its motherboard fried a month later. when the store sent a technician to replace it under warranty they recommended the appliance surge protectors |

asciilifeform: don't know for sure about surges but regularly notice e.g. lights dimming slightly, so the power definitely isn't clean and consistent |

~ 1 hours 8 minutes ~ |

asciilifeform simply has a rack-mounted 'double convert' ups + expanders, to which ~errything of any value is connected |
11:48 |
asciilifeform |
has built-in MOVs for surge (tho would have to desolder if they were to blow. to date never happened.) |
11:49 |
asciilifeform |
also reports min/max voltages etc. |
11:52 |
asciilifeform |
( subj fwiw. if you have moar than 1.8kW of load, would need fatter one.) |
11:54 |
asciilifeform |
with expander (and reasonably-fresh cells), ~40min of time at full load, moar than enuff time to change oil in generator. |
| |
~ 42 minutes ~ |
12:37 |
billymg |
asciilifeform: neat. for fridges i don't worry about 'uptime', just not frying them |
12:37 |
billymg |
since everything these days seems come with a motherboard |
| |
~ 17 minutes ~ |

asciilifeform still has 'analogue' fridge, lol |
| |
~ 38 minutes ~ |

phf: moar re new crapples : on 'm2' fanless lappy, built ffa, and this benchmark ran in 1min 41s. |

Logged on 2022-11-18 12:32:30 phf[awt]: meanwhile you have x86 market working with a very modular design, that necessarily creates overhead. so the whole "m1 totally slaughters legacy intel!!1" narrative is essentially a bunch of idiots going "bauaah duuuh standard bad, ipad render new york times fast good!!" |
13:38 |
asciilifeform |
phf: for comparison: 2m 49s on 'threadripper' 3960X. |

and, as given in orig. article, on 'opteron' 6328 : 7m 24.751s. |
13:41 |
asciilifeform |
phf: evidently the optimizations ~not~ 'crappleware-only'. ( and this was with unadorned gnat, w/out any crapple proprietary arm compilers. ) |
13:42 |
asciilifeform |
pity they dun sell 'm2' in a fat rackable box, where could scrape off the crappleware and use as generic comp. |
13:43 |
asciilifeform |
currently appears to be the fastest (single-core, at any rate) cpu in asciilifeform's torture chamber. |

asciilifeform was quite skeptical, and convinced 'benchmarks -- lies' etc. but troo phakt. |
13:44 |
asciilifeform |
notbad for a box that pulls ~20 watt (less when lcd off..) |
13:45 |
asciilifeform |
and, note, this was w/out asm inlines. |

(asciilifeform) 2022-06-24 asciilifeform: for 'magic instrs' yer stuck with 'intrinsics' (of which gnat gives next to nuffin) and then of course asmism |
13:47 |

asciilifeform expected the crapple to be warm enuff 'to fry egg' , at least, after this -- but nope. |
13:51 |
* |
asciilifeform ftr not found any anti-constanttime booby on 'm2'. |
13:52 |
asciilifeform |
the adhoc heathen gnat asciilifeform used on that box. (gnat in 'macports' appears to be 100% broken.) |
13:58 |
* |
asciilifeform to be fair not tried erry possible arm64; previously, only rk3328 (which goes at ~half the speed of opteron 6328, which still aintbad considering that it runs under <5W) |
13:58 |
asciilifeform |
x86 suxx, noose at 11. |

~ 16 minutes ~ |

asciilifeform |
ftr, how to run: 1) throw out the flags (e.g. '-static') that dunwork on crapple gnat; 2) in limits.ads, up the max tape from 1MB to 12MB 3) up the stack to max crapple permits: ulimit -s 65520 3) : |

( steps 2 and 3 needed on x86 also ) |

asciilifeform thinking about it, the above aint a 'universal' benchmark at all, as the calculation very much fits in cache (on all 3 boxes.) but still interesting. |

asciilifeform |
(i.e. fact that crapple's thing has ~1cm memory bus, not relevant here) |

asciilifeform not has the arm 'neon' phf mentioned ; may be interesting to try on it |
