My thoughts on MessagePack

Hi. My name is Sadayuki "Sada" Furuhashi. I am the author of the MessagePack serialization format as well as its implementation in C/C++/Ruby.

Recently, MessagePack made it to the front page of Hacker News with this blog entry by Olaf, the creator of the Facebook game ZeroPilot. In the comment thread, there were several criticisms for the blog post as well as MessagePack itself, and I thought this was a good opportunity for me to address the questions and share my thoughts.

My high-level response to the comments

To the best of my understanding, roughly speaking, the criticisms fell into the following two categories.

What the Hell? -- A Journey Through the Nine Circles of Python Packing

Writing a setup.py

I am no Virgil, but having stumbled my way through Python packaging a few times already, I'm documenting the things I learn as I go here.

To help me learn, I took a survey of the top 15 Python packages on Github along with 12 other commonly referenced packages. I thought... if there are any best

The difference between XYZ and TMS tiles and how to convert between them

Lots of tile-based maps use either the XYZ or TMS scheme. These are the maps that have tiles ending in /0/0/0.png or something. Sometimes if it's a script, it'll look like &z=0&y=0&x=0 instead. Anyway, these are usually maps in Spherical Mercator.

Good examples are OpenStreetMap, Google Maps, MapBox, MapQuest, etc. Lots of maps.

Most of those are in XYZ. The best documentation for that is slippy map tilenames on the OSM Wiki, and Klokan's Tiles a la Google.

Anonymising PDFs

PDF metadata

Metadata in PDF files can be stored in at least two places:

• the Info Dictionary, a limited set of key/value pairs
• XMP packets, which contain RDF statements expressed as XML

Fix SVG in <img> tags not scaling in IE9, IE10, IE11

IE9, IE10, and IE11 don't properly scale SVG files added with img tags when viewBox, width and height attributes are specified. View this codepen on the different browsers.

Image heights will not scale when the images are inside containers narrower than image widths. This can be resolved in 2 ways.

Use sed in bash to remove width and height attributes in SVG files

As per this answer on Stackoverflow, the issue can be resolved by removing just the width and height attributes.

git tag -d 12345

git push origin :refs/tags/12345
# alternative approach
git push --delete origin tagName
git tag -d tagName
