I remember the hoopla when Apple achieved a 1 GFLOP desktop with the G4 chip, the threshold for calling something a supercomputer. Times have changed.

Rubber Soul was always my favorite album, an impossible choice to make. They finished the transition from pop to rock icons that started in Help!. Fantastic song structure, chord voicings, melody, harmony, lyrics, the whole package. Rick Beato has a good ear for those arpeggios.
Rubber Soul is definitely on my desert island album list.

Will she still believe it when he's dead?"

Yeah I play guitar. I had a sweet Fostex 4-track recorder in high school, only got rid of it a couple years ago. I learned to play through church songs, simple 1, 4, 5, minor 3rd. So much popular music is that. I still call them church songs.
Small world. Fostex X-15 I think, still have mine in a box in the basement. IIRC Boston does a nice job of staying in the relative keys, I think G Em in More than a feeling. Except I think one orphaned Eflat chord. The Beatles occasionally threw in IImaj like in Hold me Tight E A F#maj B,A, repeat and also E E A Am E. Just about wore out that 8 track tape. I'm a Strat guy with a hot lead pickup. Same guitar for 45 years now. Gonna pass it on to my son. Late 70's Deluxe Reverb - because I saw Max Webster (Kim Mitchell) absolutely kick ass using one. Just before they broke up. Got tired of 4 6L6 4x12 hp. and weight!

Think I had the Fostex XR5, got it in '96. Cool tech at the time. I'm on an old Yamaha acoustic, strung with nylon. I was a Strat guy when I was younger, but now the Tele seems cooler for some reason. Maybe someday...
Heard this on the radio today. Trying to mentally figure the I IV V VIm IIm III7 fit is a tough one. Wash your brain plum clean. Too much for me. I found some instructional videos and spotted that the song is basicly in E but changes to Em/Gmaj to mess with your head and for one final twist throws in a VImaj against the E base. I think the keyboard add ons decorate and obfuscate the chords quite well. Enjoy.

good gawd! this guitar player is reading sheet music to play that! you can see someone turn the page

Plagiarizing a post by user byQ 2014 hearth.com. I knew there were different firebricks but this is more in depth.
quote:
I'm building a masonry heater and I've did some research on firebrick. What I learned is firebrick generally comes in 3 or 4 duty statuses. The higher the duty status the more metal (alumina, up to 99%) and less sand (silica). The lower status firebricks will have like 20% metal in them and 80% sand. The more metal in the brick the better, right?
Not necessarily. The super duty/high metal bricks don't expand and contract very well - they form little fractures within the bricks. Wood stoves heat up and cool down so these bricks may not like this. They do better if they get very hot and stay hot (like in an incinerator). However these super duty bricks won't pit out like some of your bricks are doing. Your bricks are low duty firebricks and probably contain about 20 to 25% metal in them. They aren't very tough but with the higher sand content they expand and contract well so they won't form little fractures within them.
The best firebrick? Probably a medium/high duty firebrick - which contains about 35-55% alumina (metal). This brick will not get the little internal fractures and it won't pit out as fast from friction. Generally, the higher the duty status of the brick the higher the cost. If you are in the midwest Whitacre Greer (20% metal brick) and Alsey refractories (the smithfield a medium/high duty firebrick) are the go to firebricks for many masons.

That is interesting to learn. And very timely, because I have to replace the fire bricks in my woodstove.
My Napoleon bricks are very heavy and dense except for the stove's front corners where light insulative bricks are used. I believe the thermal mass helps fire off reloads. On a clean-out reload the grey ashes come out blistering hot and I'm sure the floor bricks are the same. I only take out 1/2 to 2/3 of the ashes and coals obviously stay in. Re expansion my bricks all fit loose. I'd keep that in mind if you go aftermarket.
Here's a wash your brain nugget. Buddy's new stove EPA test info on Low burn 14.500 BTU/hr draft 0.05" H2O while on High burn 40,000 BTU/hr but sefl established draft at 0.08" H2O. So your draft does change with fire states, both considered normally operating. I intuitively figured that but had never seen a hard measurement till now.
Somewhat of a cross/repost from Monitoring Woodstove Burn or at least I hope that title is close, in the spirit of Nerd and washing your brain cleaner than a dog's w__ner - some reel lurnin' - I repost the hearth.com post that takes you to trainman on github. Left my Arduino cpu running since last season, just unpowered the air servo during the summer - and it picked up and went right back into service. Sweet. A reboot triggers an optional fresh data logging file. Pretty well understood by now don't need more data.

Wood stove automation using the Raspberry Pi
Happy New Year! It has been a couple of years since I started working on my wood stove automation project. Its based on Python and currently runs on a Raspberry Pi3 Model B. I got quite far but until now I never documented any part of what I did. Took me about a week to take pictures and...
