HN discussionhere's how my quantizer does: full-color, undithered, floyed-dithered: http://imgur.com/a/lrLTd#0 repo: https://github.com/leeoniya/RgbQuant.js demos: http://o-0.me/RgbQuant/ this image is actually a pretty poor example of quantization, it's too easy. full color gradients give a much better indicator of behavior, quality and performance. if you really are interested in different algorithms, check this out: http://ww…

HN discussionI think of it slightly differently - "I really appreciate the direction that Microsoft developer tools division has been heading with their adoption of open source for a growing number of their products. They deserve big credit. But devs appreciate open source more than other consumers. it's hard to see how open source would work for, say, the parts of Microsoft that make Windows, Office or Xboxes. it's easy for dev…

HN discussion I think this pretty well reflects Microsoft's long-term consumer risk, too. More than half of MSFT's revenue ( http://www.tannerhelland.com/4273/microsoft-money-updated-20... ) comes from Windows and Office (and over half the profit, Windows http://news.yahoo.com/microsoft-defer-revenue-windows-upgrad... ). Back in the 90s and early 00s, the rate of change in the PC market was amazing. The hardware you could buy in…

HN discussionThere is no such thing as an OSX server. You mean a mac mini with OSX server edition on it? There's basically nothing that IBM does that will work on an iOS device, nevermind well. This deal is hot air, Cringely is right. Microsoft make their money on office and exchange, as much as it pains me to point the obvious.

HN discussion85% of the Microsoft Business division that is responsible for Microsoft Office comes, not unsurprisingly, from businesses: http://www.tannerhelland.com/4993/microsoft-money-updated-20... Edit: The point I was trying to make is that I wonder how important personal use of Office is to Microsoft. Arguably people either want to use what they use at work or they use something other product (in the past one of the compet…

on “HyperDither”Win 8 moves ~40,000,000 licenses in first month. Upgrades are $39.99. Win 7 moved ~30,000,000 in month one. Upgrades were $120 - 220/upgrade. Vista moved 20,000,000 first month. Upgrades were $129 - 299. MSFT is offering the DVD-version of Windows 8 for ~$30/more per copy so let's just pretend that the fair price for comparison of Windows 8 is $69.99 (since I assume far more physical media went out of Win 7 in 2009)…
