 10:06 <@matches> Must find motivation to work on Lit Review at 10am...

+13:04 <@matches> I wanted to rasterise a vector image so I could compare them at the same scale ("These look the same!") and zoomed ("This one looks crappier!)
+13:04 <@matches> But because vector graphics editor/viewers don't use pixels as units but they do when they export to a bitmap, it's difficult to actually get them to look the same
+13:04 <@matches> Before scaling
+13:05 <@matches> I guess a screenshot tool might be the best way
+13:06 <@matches> I don't know if I need to do this really
+13:07 <@matches> I guess Mechanical and Chemical engineers marking this will probably benefit from having an example
+13:07 <@matches> Doesn't everyone know the difference between vector and raster graphics
+13:07 <@matches> Where was that paper that had tux vector and rasterised
+13:10 <@matches> Ah, worth2003xr.pdf
+13:11 <@matches> If it's in a paper I guess it can go in a Lit Review
+13:11 <@matches> At least until I have something better
+13:15 <@matches> Kind of ironic that the image I am using was actually scanned first as a bitmap and then converted to vector using Trace Bitmap
+13:57 <@matches> Ah, it's actually impossible to get it to be exactly the same, because even taking a screenshot on my own screen it will then be different depending on the display of whoever reads the digital pdf
+13:57 <@matches> Oh well
+13:58 <@matches> I suppose "It looks shittier" will have to suffice without trying to make them look exactly the same before scaling
+13:59 <@matches> I have spent WAY too long making this example
+13:59 <@matches> I could have just gone "See \cite{worth2003xr.pdf}"
+16:00 <@matches> So it might be worth talking about dpi in pdf viewers and how it SUCKS

+21:46 <@matches> I have perpetrated XML on the codebase
+21:47 <@matches> I have grand visions of our code supporting SVGs
+21:47 <@matches> I also have grand visions of actually doing a Literature Review
+21:50  * sulix git pull's with some trepidation.
+21:52 < sulix> Never heard of pugixml before but it looks okay.
+21:55 <@matches> The W3C XML specification is pretty terrifying
+21:56 <@matches> I will feel more like I've satisfied the "Document Formats" part of the Literature Review if I say some things about it
+21:57 <@matches> Well SVG in particular
+21:57 <@matches> SVG defines a "minimum" precision of IEEE binary32 
+21:58 <@matches> But there's a specification for "High Quality" viewers that have to use binary64
+21:58 <@matches> That's probably the only real thing relevant directly to our problem

+01:23 <@matches> It's May 1st
+01:23 <@matches> This means we can no longer say "The Literature Review is due Next Month"
+01:23 <@matches> IT'S DUE THIS MONTH
+01:23  * matches freaks out
+01:23 <@matches> ... but after sleep
+01:25 <@matches> Page 12 of my Literature Review by the way
+01:25 <@matches> Is the only page I like
+16:34 <@matches> The C version of paranoia compiled for me
+16:34 <@matches> Not terribly exciting (I have an IEEE 754 compatible processor! Amazing)
+22:17 <@matches> W Kahan's website is a very interesting if slightly difficult read
+22:24 <@matches> He appears to have written this 80 page pdf in a day
+22:27 <@matches> It kind of reads like one of those religious propaganda pamphlets
+22:27 <@matches> "Java is the Work of Satan"
+22:27 <@matches> "Kernighan-Ritcie C floating-point semantics are the light"
+22:28 <@matches> But every so often he has a graph or example that makes him seem less crazy
+22:34 <@matches> "And now Java forbits you to mention or use extra-precise long double arithmetic, though IEEE Standard 754 recommends its use and over 95% of computers on desktops have it built into their hardware. You paid for it, but Java denies you its benefits."
+22:34 <@matches> Java has long double now right?
+22:34 <@matches> Although that JOP I was looking at was just 32 bit
+22:36 <@matches> Ah, java.lang.math.BigDecimal
+22:37 <@matches> "But be careful with division, because it will throw exceptions if it's like 1/3, then it will be Non-terminating decimal expansion."
+22:37 <@matches> That sounds horrifying
