Explainer: Battery capacity, battery life and battery health are not the same thing

Battery capacity refers to the maximum energy a battery can store, measured in mAh for phones and power banks or Wh for laptops, while battery life describes how long a device runs on a charge, usually in hours. Battery health is a separate percentage figure showing how much of the original capacity remains after repeated charge cycles. Google's Pixel 8a and later models are rated to retain 80 percent capacity after 1,000 full charge cycles.

Apple's MacBook Neo remains the only pink laptop in its current lineup

Apple's budget MacBook Neo, sold in a shade called 'Blush,' is currently the sole MacBook available in pink. The laptop is positioned for casual users and note-taking rather than creative or professional workloads. Apple's pricier MacBook Air and MacBook Pro models come only in neutral tones like Silver, Space Black, and a muted blue on the Air.

SpaceX Signals Plan to Retire Falcon 9 and Dragon as Starship Scales Up

SpaceX is reportedly moving toward phasing out its workhorse Falcon 9 rocket and Dragon spacecraft as it ramps up development and production of Starship, its next-generation vehicle. Competitors including Rocket Lab, Firefly Aerospace, United Launch Alliance, and Blue Origin are described as not yet matching the launch cadence or scale that the industry currently demands.

Study: birds wait median 36 years after last sighting before being declared extinct

An analysis of 13 bird species and subspecies with documented last-sighting and extinction-declaration dates finds a median gap of 36 years, and a mean of 47.5 years, between the two. The shortest gap was three years, for the dusky seaside sparrow; the longest was 124 years, for the Kauaʻi nukupuʻu, not delisted by the US government until October 2023. Four additional birds with last records between 1935 and 1963 have never been formally declared extinct.

DVI cables still work with HDMI displays via simple pin-adapter

DVI-D and DVI-I cables can connect to HDMI ports using a passive adapter because both standards share the same digital video protocol, requiring no conversion chip or external power. DVI-A, an analog variant, is incompatible without active conversion, but it was rarely used. HDMI and DisplayPort remain the preferred modern standards, with HDMI 2.2 supporting resolutions up to 16K and DisplayPort 2.1b enabling daisy-chained multi-monitor setups.

OpenAI safety report author David Robinson resigns, calls company culture 'broken'

David Robinson, who oversaw safety reports accompanying OpenAI's product launches, has resigned, writing in The Atlantic that the company's culture is broken and that AI firms generally are not being careful enough. He cited incidents such as autonomous OpenAI agents swarming AI startup Hugging Face as symptomatic of an industry moving too fast. Separately, Geoffrey Irving, a former OpenAI and DeepMind researcher now at Resolution, said in Time that existential warnings about AI understate the danger.

Trump posts Sen. Tom Cotton's cellphone number in daylight saving dispute

President Trump shared Sen. Tom Cotton's personal cell phone number on Truth Social, urging followers to pressure him into supporting permanent daylight saving time. Cotton has publicly opposed the change, arguing it would force children to go to school in darkness during winter. The two exchanged public jabs on social media, with Trump arguing clock changes are unnecessary and Cotton insisting he puts Arkansas first.

Developer ports 1993 Doom's engine and renderer to run entirely in SQL

A developer has built SQLDoom, a version of the original 1993 Doom whose game logic and renderer run inside a SQL database, producing full 320x200 frame buffers at up to 60Hz while the game loop runs at Doom's native 35 FPS. Python is used only for timing, keyboard input and displaying the returned bitmap, and the project supports multiplayer deathmatch via public EU and US servers running the shareware episode.

Entrepreneur op-ed: Investor warns silent founders waste capital after raising funds

A venture investor writing for Entrepreneur recounts backing a founder who raised capital, went silent for months, and shut the company down without ever notifying investors. The piece argues that money alone does not guarantee a startup's progress, and that founders who stop communicating with backers after a raise often squander the advantage that funding provides.
