How to implement Dynamic SQL in PostgreSQL 10

Dynamic SQL in PostgreSQL allows developers to streamline querying processes and reduce repetitive tasks. It is implemented using the EXECUTE statement, which evaluates a string input. Dynamic SQL can be used for executing DDL statements, such as analyzing tables within a schema, and for DML statements, enabling interactive data manipulation, like filtering results in a billing application. PL/pgSQL caching can lead to inefficiencies in dynamic SQL scenarios where execution plans vary. Security risks, particularly SQL injection vulnerabilities, are associated with dynamic SQL. Recommended practices to mitigate these risks include using the USING clause for parameterized statements, employing the format function for query construction, and utilizing functions like quote_ident() and quote_literal() for proper formatting.

Google’s analytical October Workspace Drop simplifies data in Sheets, bolsters AI security

Google has released updates for its Workspace suite in October, enhancing data comprehension, structure, and formatting in Sheets through Gemini AI. Key features include improved understanding of complex instructions for data manipulation. Google Drive has introduced a ransomware detection feature for desktop users, which alerts them to suspicious activity and pauses data synchronization. Gmail now includes end-to-end encryption for emails to enhance privacy and security. These updates build on August's enhancements, which featured file summaries for Chat, Video Overviews for NotebookLM, and the Veo 3 model in the Vids app, with the recent transition to Veo 3.1 providing greater creative control, improved sound capabilities, and more realistic textures.

5 PowerShell tricks that beat Bash on Windows

Bash is the preferred shell for many developers in Linux environments due to its robust capabilities and flexibility. PowerShell is gaining popularity on Windows for its modern functionalities, user-friendly interface, and integration with the operating system. PowerShell handles output as objects, allowing for easier data manipulation compared to Bash, which outputs plain text. PowerShell can interact with system-level components like the registry and services, enabling tasks such as querying startup applications or managing services directly. It features cmdlets that follow a Verb-Noun syntax, making commands intuitive and reusable, and supports modules for enhanced functionality. PowerShell also excels in file management and offers remoting capabilities, allowing command execution on remote machines without third-party tools. Overall, PowerShell provides better scripting and ease of use for Windows users compared to Bash.

I stored a file inside Pokémon Emerald’s in-game PC so you don’t have to

Pokémon Emerald allows for data storage through a tool called mon-fs, which encodes files as Pokémon. Each Pokémon carries 68 bits of data, including attributes like species and gender. The mon-fs tool has two modes: Lite, which stores files up to 3.2 KB, and Full, which supports files up to 10.8 KB but requires a save editor. Players can effectively use four Pokémon—Poochyena, Whismur, Taillow, and Nincada—for data storage, each having a 20% or higher appearance rate on Route 116. A web utility assists users in capturing and naming Pokémon to represent their data, but the process is time-consuming and not efficient for file transfer.

PostgreSQL 18: Part 4, or CommitFest 2025-01

PostgreSQL 18 includes significant enhancements in monitoring capabilities and new features. Key updates include: - Buffer information in EXPLAIN ANALYZE is now enabled by default, providing detailed buffer statistics for better query performance insights. - The pg_stat_io view tracks I/O statistics in bytes (read_bytes, write_bytes, extend_bytes), simplifying monitoring of I/O operations. - Enhanced monitoring of Write-Ahead Logging (WAL) statistics is introduced, allowing tracking of WAL operations and new WAL segment initialization. - The pg_stat_get_backend_io function provides I/O statistics for specific client processes, aiding in performance tuning. - The VACUUM (verbose) command now includes visibility map information, detailing all-visible pages after a vacuum operation. - The pg_stat_all_table view tracks total vacuum and analysis times per table, and users can adjust autovacuum workers without server restarts. - A new uuidv7 function generates UUIDs with a Unix-epoch timestamp for ordered identifiers. - The passwordcheck extension enforces a minimum password length for better security practices. - Improvements to the jsonb type ensure correct handling of null conversions. - The casefold function facilitates case-insensitive searches. - The RETURNING clause in DML commands now supports returning both old and new values. - The to_number function can convert Roman numerals to numeric values.

Why You Should Use a PostgreSQL GUI Instead of the Command Line

PostgreSQL is a robust and reliable open-source database system. A graphical user interface (GUI) offers several benefits over the command line, including: - Easier navigation through databases without memorizing commands. - Better organization of data in structured views like tables or charts. - Simplified query creation with user-friendly editors that include syntax highlighting and suggestions. - Time-saving tools that streamline tasks with built-in shortcuts. - Visual feedback displaying query results in sortable and filterable tables. - Learning support for newcomers with tooltips and example queries. - Fewer errors by monitoring user input and flagging issues before execution. - Enhanced collaboration features for teams, including shared connections and real-time updates. - Customization options allowing users to modify layouts and save queries to fit their workflows.

CISA tags Windows, Cisco vulnerabilities as actively exploited

The Cybersecurity and Infrastructure Security Agency (CISA) has issued an advisory for U.S. federal agencies to enhance their defenses against cyberattacks targeting vulnerabilities in Cisco and Windows systems. Two specific vulnerabilities have been identified: 1. CVE-2023-20118, which allows attackers to execute arbitrary commands on certain VPN routers, requiring valid administrative credentials for exploitation. This vulnerability can be combined with CVE-2023-20025, an authentication bypass that grants root privileges to attackers. Cisco acknowledged this issue in an advisory in January 2023, with proof-of-concept exploit code publicly available. 2. CVE-2018-8639, a Win32k elevation of privilege flaw that allows local attackers to execute arbitrary code in kernel mode, enabling data manipulation and unauthorized account creation. Microsoft issued a security advisory regarding this vulnerability in December 2018, affecting both client and server platforms. CISA has added both vulnerabilities to its Known Exploited Vulnerabilities catalog, requiring Federal Civilian Executive Branch agencies to secure their networks against these vulnerabilities by March 23, as per the Binding Operational Directive 22-01. Additionally, CISA has alerted federal agencies to another critical vulnerability, CVE-2024-21413, in Microsoft Outlook, requiring patches by February 27.
