use sharepoint as B2B extranet

 pros: if you are already a Microsoft365 user, just as easy as "one more click" less maintenance than "do it yourself" in house ( on premises ) build 3 minute read   collaborate with guests in a site  

sharepoint: hub site concept

your organisation is  3 dimensional ( or more ), hub sites turn it into a flat hierarchy connective tissue ( aka departments or divisions in a organisation) is: hub sites used to connect communications( or what you want to achieve, or function) and teams   Important: planning your hub site how to create hub sites

sharepoint: how to delete member

for example, to remove a member from children_team  

sharepoint: how to add members

 first of all, the user needs to be already a microsoft365 user, eg, already have microsoft email, or onmicrosoft email example: add member to children team

sharepoint: how to delete subsites

 eg , to delete documents folder

sharepoint: how to create subsites

泰摩栗子x手磨 Timemore chestnut X

 24 steps per revolution x 5 microsteps = 120 microsteps steps per revolution chestnut said in kickstarter, one step is 80 um??, and one microstep is 15 um?? In the chestnut x manual: Espresso 5-7 clicks (6 -12 clicks in G1) Pour over 15-18 clicks (15 -24 clicks in G1) French Press 18-22 click (24 clicks in G1) so for X, the coarser steps are similar to G1 the microsteps mechanism seems to be based on ball bearing and different pit depths of 5 settings. as it is using aluminum as material, i am not sure how durable or rigid it can be. how to make sure it is 15 microns per microsteps. It is well below normal specified tolerances ( +/- 50 microns) and the locking by spring force? spring force is definitely not strong enough to hold the microns changes. Seems to me such microsteps is just marketing gimmick. cross-cut + conical burr : faster cutting in coarse cutting phase. Some says the grinding speed is now as fast as C40 CNC milled aluminium body well, normal CNC milling is +/-0.05...

Scott Tilley

Scott Tilley (VE7TIL): The Amateur Astronomer Who Found a Lost NASA Satellite Amateur astronomer Scott Tilley was in his home office on a recent evening, using his radio equipment to scan space in a needle-in-a-haystack search for a spy satellite operated by the U.S. Air Force. Tilley, 47, launches himself on missions like this nightly. Since he was about 8, he has been a devoted but earthbound space explorer, looking for hidden satellites in the sky for hours on end. As he scanned the skies that night a few weeks ago, he did not find what he was looking for, but he came across something possibly even better: a different satellite, a weather craft NASA lost more than a decade ago. NASA had searched for the spacecraft, worth about $150 million, for two years before giving up. For an amateur astronomer, it was the stuff of dreams. “By far, it’s the most important thing I’ve discovered,” said Tilley, an electrical engineer. “It’s a pretty cool thing in my world.” Tilley, who lives in Brit...

osiris-rex TAG

 on 21 Oct, 2020 natural feature tracking ( NFT) guardian 23 Oct:   stuffed with so much asteroid rubble from this week’s grab that the flap is jammed open and precious particles are drifting away in space, scientists said on Friday. Scientists announced the news three days after the spacecraft named Osiris-Rex briefly touched asteroid Bennu 200m miles away. The mission’s lead scientist, Dante Lauretta, said Tuesday’s operation collected far more material than expected for return to Earth – in the hundreds of grams. The sample container on the end of the robot arm penetrated so deeply into the asteroid and with such force, however, that rocks got sucked in and became wedged around the rim of the lid. The team was scrambling to put the sample container into the return capsule as early as Tuesday – much sooner than originally planned – for the long trip home. Particles are continuing to escape, and scientists want to minimize the loss. “Time is of the essence,” said Thomas Zurbu...

requirements of an espresso grinder

    From David Schomer : A condensed list of additional features and capabilities critical to an espresso grinder includes:     a) Retention of less than 1 gram (g) of chambered ground coffee     b) Grinding output speed of no more than 2g per second.     c) Propulsion of powder into the portafilter with no clumping or micro-particle drift     d) Cessation of grinding upon achieving an exact dose by gram weight (+/- 0.1g)     e) Temperature Control: The powder must remain between 32°C to 35°C.   outcome: controlled Flow Rate. for espresso, too-fast shot that reaches full volume in less than 25 seconds will have a flavor profile dominated by sour/astringent notes. Too slow, extracting 25ml in 33 sec, and the flavor might be hollow, sour, or bitter. ( yield extraction) What features are key in maintaining an ideal flow rate of the shot? Stepless grind setting adjustments Dosing by weight Low retentio...

wilfa uniform grinder

 wilfa it is actually from Palico coffee, named as palico pro burr : 58 mm flat burr  40 steps with digital scale ( bluetooth and app ) measured from picture, the threads is ~1.08mm,  58 steps per rotation each step size is 18~20 um so far, the reviews online said it is very good for hand pour or aeropress, and is fine enough for espresso, albeit it is not a stepless grinder

juice extractor

 most expensive or hi tech part of whole machine The fruit is cut by bottom rotating cutting disc. By centrifugal force, the juice is forced out of the tiny slits on the sides. the slits are 2 mm * 0.05 mm . to balance for high speed rotation, several holes  of metal is drilled away:   the bottom cutting plate is made of titanium reinforced  stainless steel
