This might be due to AppArmor denying the MySQL server access to most of the filesystem. You can instead use
LOAD DATA LOCAL INFILE ...
to pipe data through the MySQL client, which can read everything the executing user can.

geordi bundles handy makandra note scripts into one gem for production database dumps, remote gem installs, and running rake tasks across environments.

MMM (MySQL Master-Master Replication Manager) is a set of flexible scripts to perform monitoring/failover and management of MySQL Master-Master replication configurations (with only one node writable at any time). The toolset also has the ability to read balance standard master/slave configurations with any number of slaves, so you can use it to move virtual IP addresses around a group of servers depending on whether they are behind in replication.

Troubleshooting broken RewriteRule and .htaccess behavior in Apache is easier with RewriteLog and high rewrite logging.

Capistrano can fail with net/ssh load errors or an Net::SSH::KnownHosts::SUPPORTED_TYPE constant error when paired with net-ssh 2.5.1. Upgrading to 2.5.2 restores compatibility.

Zero-byte downloads in Rails 3 behind Apache/Passenger often come from missing X-Sendfile support, leaving file responses empty.

Mac OS X Lion 10.7.2 can ignore /etc/hosts and break local name resolution, so Apache virtual hosts and Passenger settings stop working as expected.

Old binary log files consume disk space and can be removed safely after retention needs are met. PURGE BINARY LOGS deletes archived logs older than a chosen cutoff.

Rails render accepts HTTP status symbols such as :bad_request, making responses more readable than numeric codes.

If your pidgin IM fails to connect to ICQ, you may need to update it. The ubuntu default sources are usually outdated.

Just follow the instructions 1-4 and 1-3 on the page linked below.

Making SSL connection work

If you can not connect using SSL, open up the account settings and enable "clientLogin". Also, your Server should be set to slogin.icq.com.

Web application developers increasingly need operational knowledge beyond coding, testing, and deploying. Traditional development workflows now overlap with running and maintaining production systems.

HTTP/2 reduces HTTP/1.1 workarounds and shifts optimization into the transport layer, improving application speed, simplicity, and robustness while enabling new performance gains.

Ruby's net/http is setup to never verify SSL certificates by default. Most ruby libraries do the same. That means that you're not verifying the identity of the server you're communicating with and are therefore exposed to man in the middle attacks. This gem monkey-patches net/http to force certificate verification and make turning it off impossible.

Browser HTTP/2 push support is inconsistent and can hurt performance instead of improving it, despite a useful model for integrating push with browser APIs.

Common I/O operations differ by orders of magnitude, making hardware latency easy to underestimate and performance bottlenecks hard to diagnose.

Generic endpoints for testing HTTP clients with slow connections, redirects, and compressed responses, useful when debugging timeout issues.

HTTP/2 changes long-held optimization rules, making some common performance tricks counterproductive for modern web delivery.

A flaw in OpenSSL and SSL/TLS can expose protected data to attackers and leak secrets from encrypted internet traffic.

Generating PDFs in Rails often means choosing between text-based reports, HTML-to-PDF rendering, and different trade-offs in layout control and browser fidelity.

Cross-platform open source Redis administration GUI for managing databases, replacing slow, clunky tools with a desktop client.

Chrome panel for inspecting Rails log data, including parameters, response times, view rendering, and database requests.

A friendly introduction to the web and HTTP’s purpose, using REST as a simple mental model for understanding request and response behavior.

Out-of-band work lets long-running tasks run outside the request/response cycle without blocking clients, reducing request latency and avoiding garbage-collection pauses.

Installing a specific Puppet release on Ubuntu Lucid avoids distro package drift and keeps configuration management behavior predictable.
