Tesla sales in Europe dropped 28% in May, marking the fifth consecutive monthly decline.

Overall European electric vehicle sales rose 25% year-on-year, highlighting Tesla’s underperformance.

China’s SAIC Motor saw a 38% jump in European sales, overtaking Tesla in the region.

Provides a simple in-process event dispatcher for Go applications.

Offers high performance, handling millions of events per second.

Supports both synchronous and asynchronous event handling.

Most ransomware checks the system language and will not install if a CIS language keyboard is detected.

Installing a Russian or Ukrainian keyboard on a Windows PC can serve as a simple defense against many Eastern European malware strains.

Ransomware groups like DarkSide exclude CIS countries to minimize local law enforcement scrutiny.

NOAA will discontinue ingesting, processing, and distributing all Defense Meteorological Satellite Program (DMSP) data by June 30, 2025.

DMSP satellites provide unique, twice-daily, high-resolution global coverage essential for monitoring hurricane development and Arctic and Antarctic sea ice.

No other US satellite program can adequately replace DMSP data, risking a regression of hurricane forecasting capabilities by decades.

The gist lists 17 security vulnerability reports submitted to curl’s bug bounty program on HackerOne.

Reported issues include buffer overflows, format string vulnerabilities, and memory leaks in various curl components.

Other vulnerabilities involve risky cryptographic algorithms, path traversal through environment variables, and protocol enforcement bypasses.

Mise provides an easy way to install, use, and manage development tools through a simple mise.toml configuration file.

It supports per-directory configurations by merging multiple mise.toml files so different folders can have distinct tool versions.

When entering a directory, mise auto-installs and activates configured tools, ensuring consistent environments across developers.

Applying body lotion dilutes skin lipids and emits phenoxyethanol, which increases OH reactivity and reduces hydroxyl radical levels by 30–140%.

Fragrances contain high ethanol content that consumes hydroxyl radicals, causing an 86% drop in the personal oxidation field despite terpenes’ potential to generate OH.

Fragrance-induced OH suppression is rapid but transient, whereas lotion effects on OH reactivity and loss persist for hours, as confirmed by multiphase kinetic and CFD models.

A Bloom filter is a probabilistic data structure that indicates if an element is definitely not in a set or may be in it.

It uses a bit vector and multiple hash functions to set bits when adding elements and to test membership.

The false positive rate depends on the number of bits (m), number of elements (n), and number of hash functions (k), and is roughly (1–e^(–kn/m))^k.

Moore’s Law of doubling transistor density every two years is hitting both physical and economic limits.

The cost to build leading-edge chip factories has risen from a few billion dollars to over $100 billion, reducing the number of viable manufacturers.

‘Nanometer’ labels on chip nodes are now marketing terms and no longer reflect actual transistor dimensions.

Malware checks Win32_Fan WMI class to detect CPU fan presence and avoid running in virtual machines.

Windows WMI reads SMBIOS type 27 (Cooling Device) for fan info and also requires SMBIOS type 28 (Temperature Probe) defined.

Xen needs a patch to override types 27 and 28 and requires prepending 32-bit size headers in smbios_firmware files.
