Teardown of a 10G SFP+ Module Reveals Heat, Chips, and a Hidden Compatibility MCU

Teardown of a 10G SFP+ Module Reveals Heat, Chips, and a Hidden Compatibility MCU

A teardown of 10Gbit SFP+ adapters shows they run hot (idle around 40°C) and can dissipate up to about 2.5W. The module houses a Marvell Alaska X 88X3310/40P PHY with a metal heatsink attached to the enclosure and an 8051-based MCU that flags the module as a 30 m multimode fiber type for compatibility. Newer Wiitek-branded modules use a newer chipset and run cooler. The takeaway is to ensure adequate airflow or use the appropriate fiber type to avoid heat-induced frame drops; older modules may discolor and stress thermally, suggesting single-mode fiber as a cooler, practical alternative.

Trump claims a more powerful second term and lays out bold foreign policy in Axios interview

Trump claims a more powerful second term and lays out bold foreign policy in Axios interview

In a sprawling Axios Show transcript, Trump argues his second term is more powerful than his first, citing a stronger economy and rebuilt military, while praising Xi and Modi as capable leaders. He paints a confrontational view of Iran—bragging about killing Soleimani and targeting Iran’s leadership—calling the JCPOA a disaster and saying Iran won’t obtain a nuclear weapon thanks to his actions. He also discusses Ukraine aid (citing Javelins), Cuba and Venezuela as future targets, and weighs AI policy, warning of misuse but asserting U.S. leadership and potential use of the Defense Production Act. Throughout, he casts himself as the indispensable, decisive leader and hints at ongoing, high-stakes geopolitical brinkmanship ahead of his presidency, including upgrades to the White House and electoral prospects.

Trump touts 'no limits' to power, courting a history-making self-image

Trump tells Axios he sees no limits to his power and embraces a 'great-man' view of leadership, praising Xi and Modi while arguing for hardline Iran policy; a forthcoming book and a NYT/SwanHaberman excerpt describe a document he showed claiming he's more powerful than Attila the Hun and Napoleon, which he posted on Truth Social (authorship disputed). He says allies matter only if they acknowledge his power, notes the economy as a constraint on widening conflict, and hints at regime change in Iran.

Chicago Readies for New Round of Severe Storms After Damaging Week

Chicago Readies for New Round of Severe Storms After Damaging Week

After a week of damaging storms that toppled trees and knocked out power to thousands, the National Weather Service warns of another round of strong to severe storms moving through Chicago on Tuesday and Wednesday, with Wednesday carrying the higher threat of damaging winds and heavy rainfall. Last week’s storms left tens of thousands without power; by Friday more than 45,000 were affected, though Sunday figures show just under 11,000 remained without power. City crews also reported around 10,000 downed trees and nearly 700 damaged traffic signals. Expect mild, dry conditions Monday, with rain tapering by Thursday.

JWST Survives a 344-Point Deployment Challenge on 1 Kilowatt of Power

JWST Survives a 344-Point Deployment Challenge on 1 Kilowatt of Power

NASA’s James Webb Space Telescope, parked at the Sun-Earth L2 point about 1.5 million kilometers from Earth, runs on roughly 1 kilowatt of power (with a solar array near 2 kW) and weathered a critical deployment sequence with 344 single-point failures—mostly tied to sunshield and mirror deployment. By January 2022, 295 of these were retired, leaving 49 primarily propulsion-related items. All 107 sunshield release devices fired and the 155 motors for aligning 18 hexagonal mirror segments operated, enabling Webb to begin its infrared observations with a remarkably power-efficient design.

NASA bets on a 'Big Bang' to stretch aging Voyager probes’ interstellar mission

NASA bets on a 'Big Bang' to stretch aging Voyager probes’ interstellar mission

NASA plans a risky “Big Bang” engineering move on Voyager 2 in May–June 2026 to swap which devices stay powered (turning off heater-related lines, turning on others) to save about 10 watts and extend the probes’ operations. If successful, Voyager 1 would undergo the same adjustment later that summer. With roughly 230 watts left for systems and a transmitter around 200 watts, the twin spacecraft—launched in 1977 and now in interstellar space (V1 since 2012, V2 since 2018)—could keep returning science into the 2030s, potentially reaching around 200 astronomical units, though power will keep dwindling and some instruments may be shut down.

Brand says he had a 16-year-old encounter that was consensual but exploitative

Russell Brand told Megyn Kelly that he slept with a 16-year-old when he was 30, calling the encounter consensual but exploitative due to a power imbalance; he notes the age of consent in the UK/Europe is 16 and says he was an immature, younger man at the time. This comes amid 2023 rape allegations against Brand which he denies, with a UK rape trial anticipated later this year.

IRGC Seizes Key Levers of Iran’s Power, Sidestepping Civilian Authority

IRGC Seizes Key Levers of Iran’s Power, Sidestepping Civilian Authority

Iran’s Islamic Revolutionary Guard Corps appears to have captured key decision-making, answering only to Supreme Leader Mojtaba Khamenei and sidelining civilian leadership. ISW and US intelligence say IRGC chief Ahmad Vahidi now makes major military and political decisions with wartime authority, and civilian officials such as the speaker of parliament and foreign minister reportedly cannot act without IRGC approval. The IRGC’s influence extends to critical moves like the Strait of Hormuz, which was alternately opened and then closed under IRGC direction, signaling a shift from clerical rule to a more IRGC-centric power structure that also reaches into the economy and regional policy.

Investigation Opened into Influencer Ashlee Jenae’s Tanzanian Death

Influencer Ashlee Jenae (Ashly Robinson) died on a celebration trip in Tanzania, found unconscious at a Zanzibar villa and pronounced dead after transport to a hospital. Tanzanian police say it is believed to be suicide, following a dispute with fiancé Joe McCann; he is cooperating and has had his passport withheld. The family has called the death suspicious and says the case is under active investigation, with authorities not accusing McCann of wrongdoing at this time.

Cuba hit by second nationwide blackout in under a week

Cuba says the entire island has suffered a second nationwide blackout, leaving more than 10 million people without power as restoration protocols begin, following an earlier grid collapse tied to fuel shortages amid sanctions that have disrupted imports from Venezuela and elsewhere and hurt tourism, hospitals, and agriculture.
