Building a high-performance mail delivery system is one thing; building one that does not knock over other systems is a different story. Some mailers suffer from the thundering herd syndrome: they literally flood other systems with mail. Postfix tries to be a fast mailer and a good neighbor at the same time.

When writing more than a trivial script in bash, I often wonder how to make the code testable.

It is typically hard to write tests for bash code, due to the fact that it is low on functions that take a value and return a value, and high on functions that check and set some aspect in the environment, modify the file-system, invoke a program, etc. - functions that depend on the environment or have side effects. Thus the setup and test code become much more complicated than the code they test.

Rather inobstrusive carousels if you're required to use one

Almost all of the testing I've managed has proven that content delivered via carousels are missed by most users. Few interact with them and many comment that they look like adverts — we've witnessed the banner blindness concept in full effect.

In terms of space saving and content promotion, a lot of competing messages get delivered in a single position that can lead to focus being lost.

I'm quite certain that they are indeed a user-interface cliché borne out of their inclusion in wire-framing apps and being part of JavaScript frameworks.

So if they’re not effective, why do people use them? 2 reasons:

- Some people think they’re cool. But cool does not make you money – at least not this way.
- Different departments and managers want to get their message on the home page. Design by committee never fails to fail.

Frameworks are one of the hugest anti-patterns in software development. They're hard to learn. They limit your creativity. They increase your project's complexity and dependencies. They go out of business and get abandoned. You have to maintain and upgrade your code to match the latest framework versions for no good reason. You have to search for help and ask others for advice when you're stuck. And you probably only need a small percentage of features that the framework offers anyway. They just don't make much sense.

The Pandanet Internet Go Server is a great place for playing, watching, studying, and enjoying the game of Go on the internet. At any time, day or night, you can find hundreds of other players from all over the world and of all playing levels, from beginners to professionals. Whatever your ability, you can find opponents of similar skill to play with.

When the code has stopped at a breakpoint, you can examine its state in the variables pane of the debugger:

Bacula is a set of computer programs that permits the system administrator to manage backup, recovery, and verification of computer data across a network of computers of different kinds. Bacula can also run entirely upon a single computer and can backup to various types of media, including tape and disk.

In technical terms, it is a network Client/Server based backup program. Bacula is relatively easy to use and efficient, while offering many advanced storage management features that make it easy to find and recover lost or damaged files. Due to its modular design, Bacula is scalable from small single computer systems to systems consisting of hundreds of computers located over a large network.

Redically simple, intelligent and robust backup & recovery for MySQL

Percona XtraBackup is the world’s only open-source, free MySQL hot backup software that performs non-blocking backups for InnoDB and XtraDB databases. With Percona XtraBackup, you can achieve the following benefits:

Backups that complete quickly and reliably
Uninterrupted transaction processing during backups
Savings on disk space and network bandwidth
Automatic backup verification
Higher uptime due to faster restore time

Percona XtraBackup makes MySQL hot backups for all versions of Percona Server, MySQL, and MariaDB. It performs streaming, compressed, and incremental MySQL backups.

Percona XtraBackup works with MySQL, MariaDB, and Percona Server. It supports completely non-blocking backups of InnoDB, XtraDB, and HailDB storage engines. In addition, it can back up the following storage engines by briefly pausing writes at the end of the backup: MyISAM, Merge, and Archive, including partitioned tables, triggers, and database options.

Percona’s enterprise-grade commercial MySQL Support contracts include support for Percona XtraBackup. We recommend support for critical production deployments.

Percona XtraBackup is an high performance, low-profile and non-blocking open-source backup utility for InnoDB and XtraDB databases.

Currently is the only open-source tool that performs backups on 'MySQL-based' servers (MySQL, MariaDB, Percona Server) that doesn't lock your database during it. Backups are online, and queries and transactions continue to run without interruption ('hot backups').

It can back up data from InnoDB, XtraDB, and MyISAM tables on MySQL 5.0 and 5.1 servers, and it has many advanced features like partial, remote, compressed and incremental backups, multi-threaded file copying for performance and Point-in-time recovery.

WebRTC (where RTC stands for Real-Time Communications) is a technology that enables audio/video streaming and data sharing between browser clients (peers). As a set of standards, WebRTC provides any browser with the ability to share application data and perform teleconferencing peer to peer, without the need to install plug-ins or third-party software.

WebRTC components are accessed with JavaScript APIs: the Network Stream API, which represents an audio or video data stream, the PeerConnection API, which allows two or more users to communicate browser-to-browser, and the DataChannel API that enables communication of other types of data for real-time gaming, text chat, file transfer, and so forth.

PeerJS simplifies WebRTC peer-to-peer data, video, and audio calls.

PeerJS wraps the browser's WebRTC implementation to provide a complete, configurable, and easy-to-use peer-to-peer connection API. Equipped with nothing but an ID, a peer can create a P2P data or media stream connection to a remote peer.
