Now please if everyone retweets this it would be very childish, I like childish !

oh my god we're living out the 80s kids movie trope of "an evil rich guy bought the community center where we hang out and is gonna destroy it"

FUCK we'd all better learn to break dance really fast

@tomchadwin Glad it made some sort of sense! LibreOffice has a MMULT function. You need to make the arrays square, so in this case you need to add a column to the right of (0,0,1) to square up both matrices before multiplying. Then you need to add a 1 to each coordinate, and it should work.

@tomchadwin Twitter isn't the best place to teach the fundamentals of vector maths 😂 /3

[GeoSpark @GeoSparkJohn]

@tomchadwin The translation op is the same as matrix(1,0,0,1,x,y) where x, y are the translation values. So you need to matrix multiply the first by the second (it's not commutative) then multiply each vertex by this new matrix. For a one-off, I'd use a spreadsheet. /2

[GeoSpark @GeoSparkJohn]

@tomchadwin The 1st 4 numbers in the matrix represent a scaling factor, with the -ve value being a flip along the y axis. The last 2 numbers are a translation. The translation operator then moves the points in the now-scaled coordinate system. /1

Just on a call to @EE tech support, when I got cut off. Apparently when they say their support is open until 8pm, they literally shut down the system 8pm 😠

@howardbutler @hobuinc Cool. Thanks!

[GeoSpark @GeoSparkJohn]

@howardbutler Is the source for the COPC viewer FOSS? We're looking to develop something similar, but don't want to reinvent stuff.

MISSING PERSON. My son Daniel Carberry has been missing since 1pm yesterday. He was last seen in the University area of Liverpool city centre and may be in a vulnerable condition. Could you please share this post and either DM me or ring 101 (Ref. 828) if he’s been seen ❤️

GREAT NEWS
My ongoing campaign to limit the number of people retweeting this image and causing any upset to Jacob Rees-Mogg has made great progress I am now so confident that nobody will RT it that I am going to tag in @Jacob_Rees_Mogg so he can see how well we're doing.
Thanks

*MISSING PERSON APPEAL*
It only takes 3.2 seconds to RT this, and help locate Sue Gray, 63, of London, last seen on the 18th February 2022.

@howardbutler @STACspec @cogeotiff @entwineio Indeed, I was being a bit flippant. I have pondered something similar in the past, and your idea sounds good. An advantage of EPT and Cesium tho is one just serves files, rather than having to seek and serve chunks. Not necessarily a big issue, and both have advantages.

Always limit your global variable changes.

You say that it’s fucked that gingerbread men live in gingerbread houses, but to a gingerbread person, gingerbread is as inscrutable and fundamental as carbon. The people and homes are no more alike than humans are to diamonds. Only we, their gods and creators, can see the horror

[GeoSpark @GeoSparkJohn]

@Raspberry_Pi Seems legit to me. Off to the supermarket to get the ingredients!
