The feeling when you find the root cause for a problem that has been bothering you for months. And it turns out to be fixable by adding a single letter. (To turn an "unsigned long" literal into an "unsigned long long" one.) (Actually I made it use the UINT64_C() macro from <cstdint>.)
Writing portable code is hard. And thanks, Windows, for keeping "long" as 32 bits even in 64-bit code.
Now, if only Clang or gcc on Linux would warn about such po…

R-Horizon: How Far Can Your Large Reasoning Model Really Go in Breadth and Depth?
Recent trends in test-time scaling for reasoning models (e.g., OpenAI o1, DeepSeek-R1) have led to remarkable improvements through long Chain-of-Thought (CoT). However, existing benchmarks mainly focus on immediate, single-horizon tasks, failing to adequately evaluate models' ability to understand and respond to complex, long-horizon scenarios. To address this incomplete evaluation of Large Reasoning Models (LRMs), we propose R-HORIZON, a method designed to stimulate long-horizon reasoning beha…

IFDECORATOR: Wrapping Instruction Following Reinforcement Learning with Verifiable Rewards
Reinforcement Learning with Verifiable Rewards (RLVR) improves instruction following capabilities of large language models (LLMs), but suffers from training inefficiency due to inadequate difficulty assessment. Moreover, RLVR is prone to over-optimization, where LLMs exploit verification shortcuts without aligning to the actual intent of user instructions. We introduce Instruction Following Decorator (IFDecorator}, a framework that wraps RLVR training into a robust and sample-efficient pipeline…

A Screen-printed, Silver-nanowire-based Optically Transparent Wideband Reconfigurable Intelligent Surface for 5G mmWave Applications
The reconfigurable intelligent surface (RIS) can help establish secondary line-of-sight links for 5G mmWave and beyond applications to cater for the large path loss and blockage in millimeter-wave direct links. It is desirable that the RISs are optically transparent so that they can be placed on building windows, etc. However, traditional transparent designs with indium tin oxide films have challenges of high loss and low transparency, while metallic meshes suffer from a large feature size for …

If you are a guy who doesn't understand* women you could try to read books by women, listen to songs by women, watch films by women etc. Maybe that is likelier to enlighten you than getting your information from obnoxious men.
* If you think I am claiming to understand women I should clarify that I don't even understand people in general.

Ionic glass formers show an inverted relation between fragility and relaxation broadness
Supercooled liquids undergo a rapid change in dynamics as they are cooled to their glass transition temperature and turn from a flowing liquid into an amorphous solid. Depending on how steeply the viscosity changes with temperature around the glass transition, glass formers are classified as strong or fragile. An empirical relation exists between the fragility of the liquid and the broadness of its relaxation spectrum. However, the microscopic origins of this correlation remain unclear and its …

I've noticed that @… has a carbon emission number for his blog at the bottom of the pages. So I've decided to try it. With 0.01g (i.e. better than 98% tested pages), it pleased my environmental conscience. I’m not sure how relevant this number is, but it did alleviate some feelings of guilt :)

Spin-wave propagation at low temperatures in YIG thin films on YSGG substrates
The use of spin waves in magnetic thin films at cryogenic temperatures has long been hindered by the lack of a suitable material platform. Yttrium iron garnet (YIG) is the leading candidate, yet it is typically grown on gadolinium gallium garnet (GGG) substrates, which develop a large paramagnetic moment at low temperatures. This substrate effect limits spin-wave propagation. In this work, we demonstrate that thin YIG films grown on yttrium scandium gallium garnet (YSGG) substrates support robu…

i recently left fedi for a bit cause i was feeling like shit and unable to do anything but spread that energy, and during that time i cobbled this together off a few loosely connected notes and thoughts for an unreleased project of mine. i dislike it but dont really know what to do about that anymore, so here u go. all words treasured.

Experimental demonstration of corrugated nanolaminate films as reflective light sails
Achieving laser-driven, reflective, relativistic light sails would represent a tremendous breakthrough for humankind, allowing us to advance our understanding of the solar system and deep space far beyond what we know from space probes, telescopes, and objects passing near Earth. Numerous sail film designs have been proposed, but none have been demonstrated that satisfy all of the stringent optical, mechanical, and mass budget constraints. Here we overcome this challenge by experimentally demon…
