In a lab setting, animals need multiple trials to learn new tasks through positive and negative reinforcement since they lack verbal instructions. Humans, on the other hand, can quickly learn new tasks with verbal or written instructions and describe them using natural language. The brain’s ability to integrate linguistic information to reorganize sensorimotor mappings for […]

The web content discusses the concept of growing virtual creatures in Minecraft Desktop using sea lanterns to search for glowstone. The process involves optimizing creatures in a physics engine, which can be time-consuming but fun. The package includes a pseudo-realistic Minecraft environment to allow individuals to grow creatures and test hypotheses. The content emphasizes the […]
Digital circuitry in FPGAs exhibits analog behaviors when pushed to extremes, offering unique opportunities beyond standard operation. Overclocking can boost performance, but requires caution due to potential chip damage. Process, voltage, and temperature variations affect chip behavior, influencing power consumption and temperature. Propagation delay limits clock speed, while glitches and metastability can be exploited for […]
The author created a 8080 processor emulator in 2000 characters of C code after winning the IOCCC. They added CP/M support for extra functionality and were surprised to win Best of Show. The program emulates the complete Intel 8080 processor, bringing back the feel of the personal computer revolution in 1975. The author provides the […]
Brain fog is a major issue for those with long COVID, and now researchers have found a link to leaky boundaries in the brain. MRI scans showed damaged blood vessels in the brains of patients with brain fog, leading to issues with memory and concentration. This is the first time leaky blood brain barriers have […]
jnv is a tool designed for navigating JSON with an interactive JSON viewer and jq filter editor. It features syntax highlighting, auto-completion for filters, and supports Identity Object, Identifier-Index, and Array Index. Notably, jnv does not require the installation of jq as it uses Rust bindings. Users can customize the interface with options like edit […]
Soul is a command line tool for setting up a SQLite REST and Realtime server. By running ‘soul -d sqlite.db -p 8000’, a REST API and a Websocket server are launched on localhost. The tool offers various options such as enabling rate limiting, configuring CORS, and starting Soul Studio. Testing can be done with a […]
The author was questioned about the validity of comparing Price Per Part (PPP) between LEGO sets, particularly regarding the inclusion of Duplo sets in the average PPP figure for a given year. This raised an interesting point about potentially skewed data and prompted a reevaluation of the PPP calculations. The author had initially added PPP […]
