Easy handle interface

Options

CURLOPT_DNS_CACHE_TIMEOUT: controls the TTL of a DNS cache entry. The default is 60s. Use -1 to keep the entry forever.
CURLOPT_RESOLVE: pre-populate the DNS cache manually.
CURLOPT_DNS_SERVERS: use alternate DNS servers (instead of system default ones). Warning: works only with c-ares (and it requires c-ares version >= 1.7.4),
CURLOPT_DNS_USE_GLOBAL_CACHE: cache DNS queries between easy handles. Warning: this is not thread-safe and documented as deprecated. Use the share interface instead (see below).

I suffer from a nagging, constant twitch to check the latest tech headlines.

On good mornings, I have time to read my RSS feeds. Most mornings, however,

Tokyo Cabinet B+ tree database

Overview

The Tokyo Cabinet B+tree database (a.k.a TCBDB) is implemented on-top of the hash database (TCHDB) that acts as the persistence layer.

Note: the same occurs with Tokyo table database (TCTDB) which is also a wrapper around the TCHDB (the table database can be thought as a document oriented database with querying capabilities).

use Valgrind 3.8.1 since 3.9.0 broke LuaJIT
build LuaJIT with the following options:

Here's a quick'n'dirty work around to install torch-svm:

Clone the repo

	# -b = bare mode (strips any leading directory
	# information from displayed filenames)

	# Get QuickBlob here: https://github.com/keenerd/quickblob
	#
	# QuickBlob comes as a C library. To use it within your own
	# program you need to implement a few functions:
	# https://github.com/keenerd/quickblob/blob/a2502b0/quickblob.h#L52-L72
	#
	# QuickBlob comes with a command-line tool that depends on DevIL library
	# but you are free to use your own image processor while integrating the
	# library into your program.
