Manages persistent connections using Net::HTTP plus a speed fix for Ruby 1.8. It's thread-safe too! Using persistent HTTP connections can dramatically increase the speed of HTTP. Creating a new HTTP connection for every request involves an extra TCP round-trip and causes TCP congestion avoidance negotiation to start over. Net::HTTP supports persistent connections with some API methods but does not handle reconnection gracefully. Net::HTTP::Persistent supports reconnection and retry according to RFC 2616.

# Excel to Code [](https://travis-ci.org/tamc/excel_to_code) excel_to_c - roughly translate some Excel files into C. excel_to_ruby - roughly translate some Excel files into Ruby. This allows spreadsheets to be: 1. Embedded in other programs, such as web servers, or optimisers 2. Without depending on any Microsoft code For example, running [these commands](examples/simple/compile.sh) turns [this spreadsheet](examples/simple/simple.xlsx) into [this Ruby code](examples/simple/ruby/simple.rb) or [this C code](examples/simple/c/simple.c). # Install Requires Ruby. Install by: gem install excel_to_code # Run To just have a go: excel_to_c <excel_file_name> This will produce a file called excelspreadsheet.c For a more complex spreadsheet: excel_to_c --compile --run-tests --settable <name of input worksheet> --prune-except <name of output worksheet> <excel file name> See the full list of options: excel_to_c --help # Gotchas, limitations and bugs 0. No custom functions, no macros for generating results 1. Results are cached. So you must call reset(), then set values, then read values. 2. It must be possible to replace INDIRECT and OFFSET formula with standard references at compile time (e.g., INDIRECT("A"&"1") is fine, INDIRECT(userInput&"3") is not. 3. Doesn't implement all functions. [See which functions are implemented](docs/Which_functions_are_implemented.md). 4. Doesn't implement references that involve range unions and lists (but does implement standard ranges) 5. Sometimes gives cells as being empty, when excel would give the cell as having a numeric value of zero 6. The generated C version does not multithread and will give bad results if you try. 7. The generated code uses floating point, rather than fully precise arithmetic, so results can differ slightly. 8. The generated code uses the sprintf approach to rounding (even-odd) rather than excel's 0.5 rounds away from zero. 9. Ranges like this: Sheet1!A10:Sheet1!B20 and 3D ranges don't work.

Enigma is a lightweight Ruby gem designed to verify passwords hashed using Firebase's custom scrypt-based algorithm, making it ideal for seamless integrations and migrations involving Firebase authentication systems. It provides a secure, efficient way to compare a user-provided password against a stored hash without exposing sensitive details, ensuring constant-time comparisons to mitigate timing attacks. Key features include: - Full compatibility with Firebase Authentication's password hashing logic, combining scrypt with AES-256-CTR encryption for signing. - Configurable parameters for scrypt (rounds, memory cost), signer keys, and salt separators. - Secure practices using OpenSSL's fixed-length comparisons. - Support for custom logging, with easy integration into Rails or other frameworks. - Minimal dependencies, relying on the 'scrypt' gem alongside Ruby's standard library. A common use case is migrating users from Firebase to systems like Devise in Ruby on Rails. During migration, extract the user's base64-encoded salt and stored hash from Firebase, then use Enigma to verify the input password. If it matches, set the raw password in Devise to generate a new hash, avoiding forced resets and ensuring a smooth transition. Whether for custom auth systems, password audits, or hybrid setups, Enigma simplifies secure verification while prioritizing ease of use.
