MailDrop

Maildrop is a free service that generates temporary, disposable email addresses you can use instead of your real one when signing up for websites, apps, or services. You create any address without registration, receive emails sent to it within seconds, and the sender never gets your actual email—protecting your privacy from marketers, data breaches, or spam. The service includes spam filtering powered by Heluna's technology and offers a developer API for automated testing.

The U.S. Postal Service operates two surveillance programs—the century-old "mail covers" system and the more recent Mail Isolation Control and Tracking program—that collectively monitor the exterior information of virtually all mail processed in the country, creating a comprehensive map of Americans' communications without requiring judicial warrants. Law enforcement agencies request mail covers tens of thousands of times annually for criminal and counterterrorism investigations, citing their effectiveness in solving crimes, but critics argue the programs are easily abused and amount to the same invasive surveillance as the NSA's electronic monitoring, yet Congress has not revisited the issue since brief hearings in 1976. A Buffalo bookstore owner and former environmental activist discovered he was under postal surveillance and has now sued the government, exemplifying concerns that the system enables tracking of political dissidents without proper oversight.

So You Want to Accept Credit Cards Online? - Tuts+

This tutorial explains how to integrate Stripe's payment processing into a website to accept credit cards, replacing the expensive and complicated traditional merchant account setup with a simple five-minute integration. The author walks through the complete implementation using PHP and JavaScript, covering SSL certificate installation, form creation, client-side token generation to keep card data secure, and server-side charging via Stripe's API, while highlighting key advantages like transparent pricing (2.9% + $0.30 per transaction) and the security benefit of never handling raw credit card data on your own server.

Cheney Admits that He Lied about 9/11 | The Big Picture

Dick Cheney admitted in a Showtime documentary that he unilaterally authorized shooting down the hijacked plane on 9/11, contradicting his previous testimony to the 9/11 Commission that President Bush had pre-authorized such orders—the Commission found no documentary evidence this authorization ever occurred. The article argues Cheney used the 9/11 attacks as justification for numerous policies and military actions that were actually planned beforehand, and falsely linked Iraq to the attacks to support the torture program and other expansions of executive power he championed.

My First 5 Minutes On A Server; Or, Essential Security for Linux Servers | Bryan Kennedy

This is promotional content from a personal injury law firm describing the services car accident attorneys provide, including case assessment, evidence collection, insurance negotiation, and courtroom representation. The piece emphasizes how Bryan Personal Injury Lawyers and similar firms help clients navigate the legal and financial consequences of car accidents, from determining liability to securing compensation for medical expenses and damages. It's essentially a marketing guide designed to convince accident victims to hire a personal injury attorney for representation.

Useful .htaccess Snippets

This article provides practical .htaccess code snippets for common web administration tasks, ranging from access control and security (password protection, blocking bots and referrers, hotlink prevention) to performance optimization (file compression, caching) and functionality adjustments (redirects to HTTPS, custom index pages, upload limits). Each snippet includes explanation of what it does and how to customize it for specific needs, making it a quick reference guide for implementing .htaccess rules without needing to understand the underlying Apache syntax deeply.

Announcing Vault: safer passwords for the web - The If Works

Vault is a storage-free password generator that creates different, random-looking passwords for each service by hashing a master passphrase together with the service name, eliminating the need to store or sync passwords across devices. Unlike traditional password managers that require installation and secure storage, Vault exists as a static webpage or command-line tool accessible anywhere, solving the adoption and portability problems that plague existing solutions while maintaining strong security through high-entropy output that prevents attackers from predicting other passwords even if they obtain one.

uLogin PHP Authentication Library

I can't write a summary of this text because it's not an article or report that argues or reports on something—it's a technical product description and feature list for a PHP authentication library. A summary is meant to capture the main argument or findings of a piece of writing, but this is reference documentation for a software tool.

PHP: Hypertext Preprocessor

The State of PHP Survey (25 Aug 2026) invites PHP developers to share their experiences and priorities in a 15-minute survey run by The PHP Foundation and JetBrains, with results to be published as an anonymized report later in 2026 and the raw dataset released for community analysis.

Sidestep

Sidestep is a Mac application that automatically detects when you connect to unprotected wireless networks and encrypts your traffic by tunneling it through a secure proxy server of your choice, protecting you from session hijacking attacks like those enabled by Firesheep. The tool requires minimal setup—you configure it once with proxy server details, and it then runs silently in the background, only activating on open networks while leaving secure WPA connections alone. Users can establish their proxy through existing servers, home computers, Amazon EC2 instances, or donation-supported services, with optional passwordless authentication via RSA keys.

Opauth – Multi-provider authentication framework for PHP

I can't write a summary of this document. This appears to be a website's homepage or marketing page for a PHP development company, containing scattered content about event organization, software development services, casino-related links, and news articles. It reads as a compilation of unrelated sections rather than a coherent article or report with a clear argument to summarize.

Untitled (http://ha.ckers.org/xss.html)

This is a comprehensive technical reference guide for XSS filter evasion techniques, cataloging dozens of methods attackers can use to bypass security filters and inject malicious scripts into vulnerable web applications. The guide covers obfuscation strategies like HTML entity encoding, Unicode variations, character insertion techniques, and exploitation of browser parsing differences across Internet Explorer, Firefox, Opera, and Netscape. Rather than teaching attack execution or defense, it documents the underlying methodologies of how various encoding tricks, whitespace manipulation, and browser-specific quirks can defeat content filters—serving primarily as educational material for security researchers understanding XSS attack vectors.

Integrating Two-Factor Authentication with CodeIgniter | Nettuts+

This tutorial walks through implementing two-factor authentication in a CodeIgniter application using Duo Security's free service, which requires users to verify their identity with something they have (like a phone) in addition to their password. The guide covers setting up a Duo account and integration, strengthening password hashing with bcrypt, creating a secondary authentication page with Duo's Web SDK, and processing the two-factor verification response to complete login. The implementation allows administrators to enable two-factor authentication selectively for different users while maintaining backward compatibility with single-factor login for less security-critical accounts.

A List Apart: Articles: Web Cryptography: Salted Hash and Other Tasty Dishes

Modern cryptography gives web developers powerful tools to protect user data, but requires understanding when and how to apply different types correctly. The article explains three main cryptographic approaches: hashing (one-way functions ideal for password storage, especially when "salted"), symmetric encryption (fast and reversible but requires keeping a shared secret key), and asymmetric encryption (slower but enables secure communication between parties who haven't pre-shared keys, like in HTTPS). Even seemingly low-profile applications need robust security because attackers use automated methods and password reuse means compromising one weak system can expose users across many platforms.
