Cloudflare Images' mixed billing model, combining prepaid storage and post-paid delivery, led to unexpectedly high and confusing invoices for EphemeraSearch, sometimes exceeding $400 instead of the expected $110.
Despite multiple contacts with Cloudflare support over eight months, no resolution was provided, prompting a switch to more cost-effective solutions like S3 or dedicated servers.
This experience underscores the importance of efficient spending for indie projects with low revenue, highlighting that while Cloudflare Images offers quality service, its billing model may not be suitable for all users.
Concerns have been raised about Cloudflare potentially overcharging for their Images service, with users reporting discrepancies in expected versus actual costs.
Comparisons are being made to other services like Amazon S3, Bunny CDN, and Cloudflare R2, which are perceived as more cost-effective alternatives.
Cloudflare's billing practices and customer support have come under scrutiny, with some users experiencing complicated billing cycles and unexpected charges.
Fabien Sanglard's exploration of the Super Nintendo (SNES) video system highlights the design decisions made by Nintendo engineers in 1989 to ensure compatibility with CRT TVs and NTSC standards.
The SNES used a master clock of 21.47727MHz, divided to achieve a dot clock of 5.3693175MHz, resulting in 341 dots per line and a 60.098Hz refresh rate, with horizontal and vertical blanking periods to avoid artifacts.
The SNES supported both NTSC and PAL standards, providing composite and S-Video outputs, and could double vertical and horizontal resolutions for specific applications, despite challenges like flickering.
The post discusses the design and architecture of the Super Nintendo Entertainment System (SNES), highlighting its technical specifications and historical context.
Key points include the SNES's resolution options, the impact of different TV standards (NTSC vs. PAL) on gameplay, and the use of CRTs (Cathode Ray Tubes) in arcade games and home consoles.
The discussion also touches on the use of SCART connectors in European TVs and the challenges of emulating the SNES's video output accurately.
Tools like clang-tidy and PVS-Studio may flag push_back as "bad style" and suggest emplace_back, but this change is not always beneficial.
emplace_back should be used to avoid creating temporary objects, but it is not related to move semantics and can still result in copies if not used correctly.
Prefer push_back for simplicity and faster compile times, using emplace_back only when necessary for non-movable types or to avoid temporary objects.
The discussion revolves around the use of emplace_back versus push_back in C++ for adding elements to containers like vectors.
emplace_back constructs an object in place, potentially avoiding unnecessary copies, while push_back adds an already constructed object to the container.
The conversation highlights that while emplace_back can be more efficient, it is also more complex, and push_back might be preferable for day-to-day use unless the specific benefits of emplace_back are needed.
Higher-kinded polymorphism, which abstracts over type constructors, is crucial for generic operations over collections and embedding typed Domain-Specific Languages (DSLs).
OCaml doesn't natively support higher-kinded polymorphism due to type aliasing issues, but it can be simulated using functors, defunctionalization, and initial algebras.
Various methods, including functor abstraction and reducing to ordinary polymorphism, allow achieving higher-kinded polymorphism in OCaml, though sometimes it may not be necessary.
Discussion on higher-kinded bounded polymorphism in OCaml, focusing on type aliases and type equality problems, which lead to higher-order unification issues.

SD Cards use NAND MLC (Multi-Level Cell) or SLC (Single-Level Cell) flash memory, abstracting complexities like block erases and wear leveling.
The card detects whether to use SPI (Serial Peripheral Interface) or SD bus upon voltage supply and initiates the appropriate software stack, completing the boot process when the software enters the transfer state.
A translation layer maps virtual to physical addresses, optimizing write performance with contiguous writes and managing overhead for random writes across Allocation Units (AUs), typically 4MB in size.
At a conference, an anecdote about dismantling broken SD cards highlighted a wear leveling bug that caused firmware to be partially overwritten, sparking discussions on SD card reliability.
Users shared experiences of SD card failures and data recovery, noting that denser memory cards are more prone to issues, while industrial-grade cards, though smaller, are more durable.
Suggestions for improving SD card reliability included better software for write aggregation and wear leveling, and self-partition-resizing SD cards to manage worn-out blocks.
