nginx upload client_max_body_size issue
...HTTP client supports it, the best way to handle this is to send an Expect: 100-Continue header. Nginx supports this correctly as of 1.2.7, and will reply with a 413 Request Entity Too Large response rather than 100 Continue if Content-Length exceeds the maximum body size.

Drawing an SVG file on a HTML5 canvas
...VG (string) paths. In other words, you can write:
var path = new Path2D('M 100,100 h 50 v 50 h 50');
ctx.stroke(path);
Live example of that here.
Old posterity answer:
There's nothing native that allows you to natively use SVG paths in canvas. You must convert yourself or use a library to do it fo...
Append an object to a list in R in amortized constant time, O(1)?
...a <- list(a, list(i)) method is fastest, at least for a problem size of 10000, but the results for a single problem size do not address the growth of the solution. For that, we need to run a minimum of two profiling tests, with differing problem sizes:

HTML5 Canvas vs. SVG vs. div
...ed and kept track of in Javascript. HTML nodes were movable Divs.
I added 100,000 nodes to each of my two tests. They performed quite differently:
The HTML test tab took forever to load (timed at slightly under 5 minutes, chrome asked to kill the page the first time). Chrome's task manager says th...
Simple insecure two-way data “obfuscation”?

Storing Data in MySQL as JSON
... who spends way too much time on stack exchange? When I have a record with 100 fields that I want to store and I only need to search on 3 or 4 of the fields, creating a table with 100 fields is nonsensical. You can store a customer record with his entire address book stored in 1 field in JSON, and j...
List comprehension rebinds names even after scope of comprehension. Is this right?
...expression. The less insane way found was single-value for clauses eg. sum100 = [s for s in [0] for i in range(1, 101) for s in [s + i]][-1], but just needs a comprehension-local var and works just as well in Python 3. I think "leaking" was the only way to set variable visible outside an expressio...
How to sort an array in Bash

Why do we use Base64?
... (or UTF-8) it will look like this:
72 101 108 108 111 10 119 111 114 108 100 33
The byte 10 is corrupted in some systems so we can base 64 encode these bytes as a Base64 string:
SGVsbG8sCndvcmxkIQ==
Which when encoded using ASCII looks like this:
83 71 86 115 98 71 56 115 67 110 100 118 99 10...
