Why iPhones Photos Often Fail to Upload and How to Fix It

·31 views

iPhones have saved photos in HEIC format by default since iOS 11, offering better compression than JPEG but limited compatibility with many upload platforms. Most browsers, including Chromium and Firefox, cannot decode HEIC files, meaning upload forms that preview or validate images may reject them outright. On Windows, viewing or converting HEIC requires installing Microsoft Store extensions, one of which may be paid, while Mac users can convert files using the built-in Preview app or the command-line tool 'sips'. iPhone users can prevent the issue entirely by going to Settings → Camera → Formats and selecting 'Most Compatible', which saves new photos as JPEG instead. Those who already have HEIC files can use browser-based tools like imging.ai to convert them locally without uploading to a server, though they should select JPG output and adjust quality to stay within file size limits.

Actuator Requirements for Robot Hands: Torque Density, Precision, and Compliance

The article explains that robot hands are among the most demanding actuator applications, since they must simultaneously meet requirements for precision, dexterity, force generation, compactness, safety, efficiency, and reliability. Unlike large industrial robot joints, robot hands must deliver human-like functions within very limited space, making actuator selection a central design decision. Key requirements include high torque density and power density, appropriate speed trade-offs, and precise positioning with low backlash and high-resolution feedback. The text also highlights repeatability, compliance for handling fragile objects and interacting with humans, precise force control, and backdrivability as critical considerations.

Why an AML 'Low Risk' Score Doesn't Guarantee a Wallet Is Clean

A crypto wallet receiving a low-risk anti-money-laundering rating does not fully settle the question of its safety, the article argues. Such scores are built from varied inputs, including direct and indirect links to flagged addresses, sanctions attribution, and unusual transaction patterns, and different providers can reach different conclusions for the same wallet. Direct exposure to a suspicious address is generally treated differently from a distant, multi-hop connection, since the number of intermediaries, timing, and quality of attribution all shape what a warning means. Blockchain history can reveal useful patterns, but it does not identify an owner or prove criminal intent. Users are advised to check what triggered an assessment, the source and currency of the data, and what the screening tool actually covers.

Robot Finger Mechanism Design: Degrees of Freedom, Kinematics, and Compliance

The article explains that robot finger mechanism design is foundational to robot hand engineering, since finger structure governs grasp stability, dexterity, payload, durability, and overall system intelligence. It notes that finger design differs from industrial arm design because fingers operate in constrained, contact-rich environments where friction, compliance, and force distribution must be considered from the outset. Key decisions discussed include the number of degrees of freedom, which trades manipulation capability against complexity, cost, and control difficulty, and the kinematic layout of links and joints, often modeled loosely on the human hand. The text also contrasts fully actuated designs with underactuated ones that use springs, tendons, or differential mechanisms, and emphasizes compliance as a means to adapt to uncertain object shapes and reduce impact failures. It concludes by highlighting the balance engineers must strike between stiffness and compliance, typically supported by finite element analysis, and noting that transmission design also strongly affects performance.

Python asyncio: Running Waiting Tasks Concurrently Without Threads

A small shop checking stock with four suppliers illustrates the problem: doing each slow check in sequence wastes time while the program sits idle. The article explains that asyncio helps when work is dominated by waiting, such as network calls or database queries, but not when the work is CPU-bound. It also notes that asyncio requires async-compatible libraries, since a blocking call stalls the whole event loop. The author advises limiting concurrency for large numbers of tasks and using plain sequential code for simple one-off scripts. The example uses asyncio.gather with simulated delays to show that four waits finish in roughly the time of the longest one.
