A tiny side-project that I can hopefully pull through: reverse engineering an audio box for kids that works with proprietary “tokens.” Like a cassette player but rigid af. Use and dispose. #hackerspace #netz39
First stop, getting info about chips and pins. A cheap USB microcontroller it i…

Electric Vehicle Identification from Behind Smart Meter Data
Electric vehicle (EV) charging loads identification from behind smart meter recordings is an indispensable aspect that enables effective decision-making for energy distributors to reach an informed and intelligent decision about the power grid's reliability. When EV charging happens behind the meter (BTM), the charging occurs on the customer side of the meter, which measures the overall electricity consumption. In other words, the charging of the EV is considered part of the customer's load and…

Rethinking HTTP API Rate Limiting: A Client-Side Approach
HTTP underpins modern Internet services, and providers enforce quotas to regulate HTTP API traffic for scalability and reliability. When requests exceed quotas, clients are throttled and must retry. Server-side enforcement protects the service. However, when independent clients' usage counts toward a shared quota, server-only controls are inefficient; clients lack visibility into others' load, causing their retry attempts to potentially fail. Indeed, retry timing is important since each attempt…

Aligning load flexibility with emissions reduction: empirical insights from a multi-site study of cryptocurrency data centers
The power sector is responsible for 32 percent of global greenhouse gas emissions. Data centers and cryptocurrencies use significant amounts of electricity and contribute to these emissions. Demand-side flexibility of data centers is one possible approach for reducing greenhouse gas emissions from these industries. To explore this, we use novel data collected from the Bitcoin mining industry to investigate the impact of load flexibility on power system decarbonization. Employing engineered metr…
