1. Marker: Convert PDF to Markdown quickly with high accuracy
Total comment counts : 29
Summary
The article discusses a tool called Marker that can convert PDF, EPUB, and MOBI files into markdown format. Marker is faster and more accurate compared to previous models and has a lower risk of generating repetitive or hallucinated text. It utilizes deep learning models and passes equation blocks through an LLM forward pass. The article provides instructions on how to use Marker and mentions some known limitations. Benchmark tests show that Marker is 10 times faster than previous models and more accurate outside of the arXiv domain. The article also mentions that Marker is suitable for noncommercial usage due to licensing restrictions but a version for commercial use is being developed. The author expresses gratitude to the creators of open source models and datasets that made Marker possible.

The article discusses the confusion surrounding the comparison between two OCR models, Nougat and Marker. Nougat was developed specifically for academic documents and has higher accuracy for arxiv documents. The author questions the comparison between Marker and Nougat in terms of speed, as Nougat was designed for academic documents and Marker converts fewer equations. However, the author recommends trying Nougat for OCR on any PDF with math, as it is easy to install and runs reasonably fast.
2. Code is run more than read

Summary
The article discusses the importance of considering the needs and experiences of users in software development. It emphasizes that code should be written and maintained with the user in mind, rather than solely focusing on the convenience of the programmer. The author argues that user satisfaction should take priority over the preferences of the development team or individual developer. Additionally, the article suggests that incorporating business perspectives, such as budget constraints and revenue generation, into the development process is important for overall success. The article also identifies common dysfunctions in software development and how they relate to the model proposed.
Top 1 Comment Summary
The article discusses how some users are compelled to use certain systems or software not because they like it, but because their company purchased it. This often puts the needs of the company above those of the actual users, leading developers to prioritize catering to the middle management rather than the users themselves. The author suggests that in such cases, developers may focus on superficial aspects like a nice login screen and reporting, while neglecting the overall user experience. They emphasize the importance of understanding the nature of the company one works for as an engineer. The article also highlights a contrast in approach, citing an online retailer that tailors its website to different countries based on user preferences, as opposed to companies that have little concern for usability since the buyers are not the users.

The article talks about the symbol “≹” which represents a relationship where two entities are not greater or lesser than each other, but not necessarily equal either. This distinction is important in situations where entities are compared in ways other than strict numerical values.
3. A reality bending mistake in Apple’s computational photography
Total comment counts : 41
Summary
A U.K. woman named Tessa Coates was photographed in a mirror with reflections that didn’t match. However, this was not a glitch in the Matrix but rather a mistake in Apple’s computational photography pipeline. When the photo was taken, Coates was moving, resulting in different images being captured. Apple’s algorithm stitched these photos together, resulting in three different versions of Coates in the image. This phenomenon can be recreated on recent iPhones and smartphones when taking photos near mirrors. Younger generations have discovered this and used it to create silly images for social media.

Top 2 Comment Summary
The author expresses their appreciation for computational photography on iPhones, particularly for capturing nighttime, low-light, and motion images. They acknowledge that these images may not be a 100% accurate representation of the original scene, but they are satisfied with the results. The author has also used techniques like HDR exposure stacking, focus stacking, and image stitching to achieve their desired images. Overall, the author values the ability to capture the subject effectively rather than aiming for pixel-perfect representations.

5. Animate Anyone: Image-to-video synthesis for character animation
Total comment counts : 26
Summary
This article discusses the challenges of generating character videos from still images and proposes a novel framework for character animation using diffusion models. The authors introduce ReferenceNet, a mechanism that merges detail features from a reference image while maintaining consistency. They also incorporate an efficient pose guider to control the character’s movements and employ a temporal modeling approach for smooth transitions between video frames. Their method can animate arbitrary characters and outperforms other image-to-video methods in character animation. The authors evaluate their approach on fashion video and human dance synthesis benchmarks and achieve state-of-the-art results.

This article discusses the development of AI that can generate realistic human movement. The author is impressed by the AI’s ability to generate natural movements, including the way fabric folds in dresses. Although the AI relies on real motion-capture data for its movement skeleton, the author is interested in the advancement of generating movement skeletons themselves. They question the progress and feasibility of models that can generate appropriate movement skeletons based on text descriptions, which could be applicable in video games.

9. Hyundai Uni Wheel electric drive system could revolutionize EV design
Total comment counts : 35
Summary
Hyundai and Kia have unveiled their Universal Wheel Drive System, known as Uni Wheel, which replaces the standard constant velocity (CV) joint in electric vehicle architecture. The system uses an arrangement of gears inside the wheel hub, offering benefits such as reduced packaging size, improved ride quality, increased durability, and higher efficiency. This could result in smaller batteries with similar or even greater range, or alternatively, larger batteries without the need for larger vehicle platforms. The Uni Wheel system has applications beyond cars and trucks and could potentially be used in scooters, motorcycles, wheelchairs, and delivery robots. The automakers have filed for and registered eight patents related to Uni Wheel in multiple countries.

This article discusses the idea of using a contraption to mount a drivetrain at the wheel or chassis of a vehicle. The placement of the contraption is arbitrary, but there are concerns about axle support and deflection control. The gears would need roller bearings and thrust support to withstand the high speeds and torque. The concept is suitable for space-constrained applications like Mars rovers, but would be challenging to compete with CV joints in regular passenger vehicles.
Top 2 Comment Summary
The article/video does not mention how the wheels can tilt/turn/angle without needing a CV joint. It is unclear how this design can accommodate steering. It is unknown if this is only for back wheel drive. The video shows the uni wheel being used in the front of a front wheel drive car, but it does not explain how the wheels steer. The functionality of steering is not explained.
10. Skyfield: Elegant Astronomy for Python
Total comment counts : 17
Summary
The article is about Skyfield, a Python package that calculates the positions of stars, planets, and satellites in orbit around the Earth. The package aims to provide results that are in agreement with the United States Naval Observatory and their Astronomical Almanac. It can compute positions for objects in either geocentric or topocentric coordinates. While it does not depend on the AstroPy library, it can accept AstroPy time objects as input and return results in AstroPy units. Skyfield can be cited by academics using the references ascl:1907.024 or 2019ascl.soft07024R. The documentation for Skyfield can be found on the main Skyfield website, while the source code and issue tracker are on different websites. The Changelog provides information on the current version’s release notes and previous updates.
