Friday tickets and 6 TB of WAL: a day in the life of a Postgres Professional support engineer

Technical support at Postgres Professional involves both troubleshooting and engineering tasks, requiring deep product knowledge and the ability to replicate issues in test environments. A notable incident involved a client whose pg_wal directory grew to 6 TB due to a checkpoint process failure, which was resolved by disabling the archive_timeout parameter. Clients typically have a strong technical background, but support engineers must also communicate effectively, especially with stressed clients. Essential skills for support engineers include a thorough understanding of Postgres Pro, operating systems, networking, and programming. Opportunities for growth within technical support are abundant, and the future may see AI taking on simpler tasks while complex cases remain for human engineers.

Windows 3.1 going full ketchup & mustard wasn’t inspired by any actual ‘Hotdog Stands’ — Veteran Microsoft designer calls it a garish choice with a catchy name

Windows 3.1 featured a color scheme known as the 'Hotdog Stand,' characterized by a garish combination of red and yellow, which was not intended as a joke but rather as a bold design choice. Virginia Howlett, a designer at Microsoft since 1985, noted that the color themes in Windows 3.1 were a radically new feature, as prior versions had minimal customization options. The Hotdog Stand scheme gained notoriety partly due to its catchy name, although it was simply a choice made during development. Additionally, Microsoft used a miniature version of Windows 3.1 for the setup installation of Windows 95, as it was fully debugged and facilitated a smoother installation process.

WhatsApp Launches EU Interoperability for Encrypted Cross-App Messaging

Meta Platforms Inc.’s WhatsApp is rolling out interoperability features across Europe, allowing users to send messages to individuals on third-party applications starting in November 2024. This initiative is in response to the European Union’s Digital Markets Act (DMA), which requires dominant tech companies to enhance competition by opening their platforms. Users will be able to communicate while maintaining end-to-end encryption, a process that has taken over three years to develop. Users must opt-in to receive messages from third-party applications, and the initial rollout is limited to specific partners. The interoperability allows for sharing text, images, voice messages, videos, and files. Meta's engineering team adapted WhatsApp's infrastructure to accommodate external services while upholding encryption standards. Concerns have been raised about potential security vulnerabilities and the implications of proposed regulations like "Chat Control" that could conflict with encryption efforts. This development could influence competitive dynamics in the messaging sector, providing smaller applications like BirdyChat and Haiket visibility by integrating with WhatsApp’s large user base. Compliance with the DMA helps Meta avoid fines while risking dilution of WhatsApp's market dominance. Privacy implications are a significant concern, with discussions around how interoperability could facilitate surveillance or compromise user security. Meta's journey involved regulatory oversight to ensure compliance with DMA objectives, and the success of this initiative could set a precedent for global standards in digital communication.

Seriously people, it’s fine the Steam Machine has just 8 GB of VRAM, but Valve ought to chill out on the ‘play every game at 4K60’ chat

Valve's Steam Machine has received a generally positive reception, but concerns have arisen regarding its allocation of 8 GB of VRAM. This issue has been a topic of contention, especially following the launch of Nvidia's RTX 4060 Ti, which also featured only 8 GB of VRAM, leading to consumer dissatisfaction. The RX 7600M, used in the Steam Machine, has 28 compute units and operates on a 128-bit bus width, making it challenging to accommodate 16 GB of VRAM without increasing costs and power consumption. Running memory modules in clamshell mode could be a solution, but it presents engineering challenges in a compact design. Increasing VRAM would raise the price, and with rising memory costs, manufacturers may prioritize regular DRAM production. Valve's decision to equip the Steam Machine with 8 GB of VRAM seems aimed at maintaining affordability, especially following the success of the Steam Deck. If the Steam Machine's price exceeds 0, the justification for its specifications may face scrutiny. There are also concerns about Valve's marketing claims regarding 4K capabilities, as the machine is likely to perform better at 1080p or 1440p rather than 4K.

Apple Built a ChatGPT-Like App You’ll—Likely—Never Get to Use

Apple has introduced an internal tool called Veritas, a chatbot application used by employees to aid in the development of Siri's upcoming AI enhancements. Veritas serves as a testing ground for generative AI technology and is not intended for public release. It allows Apple staff to manage conversations, store chats, and engage in dialogues on various topics. The tool supports the internal testing of new technologies for Siri, which is undergoing a significant overhaul codenamed Linwood, aimed at making Siri a more powerful personal assistant. This project has faced delays due to engineering challenges and has resulted in changes to Apple’s AI leadership. The upgraded Siri is expected to debut as early as March, with ongoing negotiations with external partners, including Google. Apple is also planning a redesigned voice assistant and AI-driven web search functionalities for future releases.

Garmin Fenix 8 Pro: LTE, MicroLED & Satellite Messaging Hands-On: Everything You Need to Know!

Garmin has launched the Fenix 8 Pro and Fenix 8 Pro MicroLED models, featuring LTE and two-way satellite messaging capabilities, increased display brightness (around 2,000 nits for the Pro model and 4,500 nits for the MicroLED), enhanced speaker loudness, and live two-way voice calls. The Fenix 8 Pro comes in 47mm and 51mm sizes, with the entry-level model priced at 9, while the MicroLED variant is priced at ,999 and only available in the 51mm size. The 43mm model has been removed due to engineering challenges with LTE integration. The new models offer various safety and communication features, including weather updates, incident detection, and emergency SOS. The LTE setup requires a subscription to Garmin’s inReach platform. The MicroLED version has a battery life of up to 10 days in smartwatch mode and 44 hours in GPS-only mode.

Looking back at Windows Longhorn

Retired Microsoft engineer Dave Plummer discussed the Windows Longhorn project, which aimed to succeed Windows XP but faced significant challenges. Longhorn was envisioned to overhaul the user experience and introduce features like WinFS for content-based file searching. However, the simultaneous development of many new features led to a fragile and bloated codebase, making it difficult to use in daily operations. A 2002 memo from Bill Gates prioritizing security diverted resources from Longhorn, further complicating development. Ultimately, in August 2004, Microsoft scrapped the existing Longhorn codebase in favor of the Windows Server 2003 SP1 codebase, integrating select Longhorn features. The project resulted in Windows Vista, which retained some Longhorn features while discarding others. Plummer reflected on the mixed legacy of Longhorn, acknowledging its failures and the lessons learned that shaped Microsoft's future practices.
