Checking task logs from Hadoop MapReduce web UI is a pain. This bookmarklet saves a lot of clicks!  Simply run this once from any page showing a table of tasks, and you'll see every task log on the same page. You can specify the amount of log to tail, and this will refresh every 30s. To circumvent web security, you need to run node-jsonp-proxy on your machine, available at: https://github.com/clintandrewhall/node-jsonp-proxy

Syntax

All target selectors start with @. The following character is the selector type. For example, @p means 'closest player'.

Target selectors may have additional, optional arguments. You can specify these in [ ], using the syntax a=0. For example, @p[a=0,b=5,c=-500].

There is a special short syntax for just specifying x, y, z and r arguments; simply list their values separated by a comma, without x=. For example: @p[100,64,-100,5] for 5 range, x=100, y=64 and z=-100. Each of these are optional and skippable by leaving them empty. For example, to just specify y coordinate: @p[,64].

Global Arguments:

• x - X coordinate for search center. Default is senders coordinate, or 0.
• y - Y coordinate for search center. Default is senders coordinate, or 0.

고수준에서 암호학 이해하기

이 글은 메아리 저널에 쓸 목적으로 한동안 작업하던 글입니다. 메아리 특유의 디자인(...)이 싫다면 여기로 링크하셔도 됩니다. 어느 쪽이든간에 의견은 이 아래의 코멘트 란 또는 메아리에 기재되어 있는 메일 주소를 써 주시면 감사하겠습니다. --lifthrasiir

암호학을 사용하는 많은 시스템은 세부적으로 무슨 알고리즘을 쓰는지보다는 그 알고리즘들이 어떻게 연결되어 있는지, 즉 구조가 실제 안전성에 더 큰 영향을 미친다. 따라서 구조와 그 구조를 이루는 빌딩 블럭을 아는 것이 중요한데, 여기에서는 이러한 암호학적 빌딩 블럭과 함께 블럭들이 어떻게 쓰여서 더 큰 구조를 만드는지를 알아 본다.

Key Exchange

키 교환. 두 사람만이 알 수 있는 새로운 키를 만든다. 이 과정이 끝나도 상대방이 내가 아는 사람인진 알 수 없지만 적어도 상대방과 내가 같은 키를 가지고 있다는 건 확신할 수 있다.

What the heck?

• Schemaless: The format does not have a knowledge about the underlying data at all.
• Byte-oriented: The format is built upon a byte stream, probably for the ease of implementation and performance.
• Binary: The format is not targeted for human consumption and specified in terms of "bytes" (which is 8 bits long for our purpose).
• Serialization: The format is primarily to be used for storage and transmission, not for the in-memory representation.

Contenders

• S-Expressions (1997), a "canonical" encoding (which is also used for transport)
