This is pragmatic follow-up part a of episode 23 maximum arrays ability just wanted to touch base quickly on the whiteboard is our discussion that I had with us at Clifford and is passenger interesting feedback from Martin Nick Radcliffe and Nick brings up another rather interesting series of observations regarding the use of a whiteboard from a non-collaborative context is something that I saw touched on briefing episode that ROI didn't go into much depth something is definitely worth discreetly talking about one of problems with with whiteboard size so it's very easy to get a small whiteboard but the larger the whiteboard in size I find that that helps and as as Nick Nickerson's is our feedback is that the larger the whiteboard the greater the area that the thinking and sketching area and thus the sheer size of the whiteboard actually will help when you come into focus ideas because you're not is constrained by space having a large canvas can make a big difference because the more information you hold then the more interconnections between information are you can draw and some at all up in a single view solicitor I a I completely agree with that sentiment and I think it's a very interesting way of thinking about the other issue he raises is colours it may sound a bit strange but I I agree that colours the more colours that you have gathered better because you can to diversify your context I hated going into meeting rooms where there is just one colour is either blue or black usually are because it you normally when you buy the pens you get Ford different colour dry erase markers are usually got black red green and is Lulu yes so bottom line is that you expect those for the minimum but as always seems to be the case arm the lighter colours seem to get dark because of the answers at 9 PM so people drawing over the dark lines destroys the tip and for whatever reason you end up getting stuck with the arm with the dodgy blue of the dodgy black marker so well I think the colour schemes and as Nick points out and in his feedback colours sort of see more natural on a whiteboard and mania Michaela Burdett the honour he also mentions are one of his extra peeves was the main one that leaves around a notice discovering that there is a marker that doesn't actually work may put it straight back in the tray on the table instead of throwing away and getting another one because that leads to a situation where you go and find small treatises talk about the bottom line is yet I really do hate those leave you if the pen doesn't work chuck it out so yes some of that were Nick think you are and see also points out the trick that I did mention on the show I was aware of and it definitely bears mention if you do cylinder has used a permanent marker on a whiteboard which you can do as you can get a dry erase marker and you can essentially draw over the top of it so if you some squiggle over the top in a thicker line the chemical that they use the dry erase marker is a solvent that stops it from permanently staying on the board and by doing that you are essentially applying that same solvent to the permanent marker and that will tend to lift the permanent marker off the board may would have caution because I've done it many times but my money were cautioned doing that is that you you will it will contaminate the marker you're using so you really do need to match the colour at something that Nick points out as well as feedback so if you've got a black Panama could use a black dry erase marker to arrays so well as a thank you very much and Nick that feedback much appreciated´┐Ż
