MSI interrupt mode explained: why it steadies GPU performance, not speed

MSI (Message Signaled Interrupts) lets a device like a GPU notify the CPU of an interrupt by writing to a memory address rather than fighting for space on a shared physical hardware line. Windows 10 and 11 default to MSI-X, an expanded version introduced with PCI 3.0 in 2010, whenever a device supports it. This approach labels each interrupt with its source, avoiding the collisions that can occur on crowded shared IRQ lines.

iPhone's Background App Refresh setting explained: what it controls and doesn't

Apple's Background App Refresh feature, found in Settings > General, lets iPhone users control which apps can update content while running in the background. Users can toggle it for Wi-Fi only, Wi-Fi and cellular, or turn it off entirely, and can also customize it on a per-app basis. Importantly, disabling this setting does not stop an app from sending notifications.

Apple rolls out iOS 27 with revamped AI-powered Siri

Apple is publicly releasing iOS 27, the newest iPhone operating system, after months of beta testing since June. The update's headline feature is an overhauled Siri chatbot built around new AI capabilities, and testers have reported gains in overall speed and stability.

APL AI-Eval Flags Two MMLU Scores as Incomparable Despite Matching Benchmark Name

An analysis by Dmitrii Zatona examines two MMLU evaluation records for the same model family—one build scoring 0.781, another 0.79—that share identical provider, metric and benchmark labels but differ in dataset split, prompt format, grader and runner network access. Under the APL AI-Eval profile, which treats each evaluation as a content-addressed frame with its own hash, a query comparing the two scores returns 'incomparable' rather than a simple +0.009 delta.

Entrepreneur Op-Ed Argues Service Firms Must Codify Founder Knowledge to Scale

A franchising expert writes that many service businesses stall once they outgrow the founder's personal oversight, because critical decisions and client know-how remain undocumented and dependent on the owner's presence. The piece argues that scaling requires converting that informal judgment into explicit decision rights and repeatable processes that employees can follow without the founder's direct involvement.

IO500 disqualifies Sugon's ParaStor F9000 storage results, Aurora reclaims top spot

The IO500 Committee removed SCNet's ISC26 submissions built on Sugon's ParaStor F9000 all-flash storage systems from its Production list after determining they failed reproducibility rules requiring public architecture details and general availability. Those entries, which had posted record-setting bandwidth and IOPS figures, were shifted to the Research list, and Argonne National Laboratory's Aurora system running DAOS storage was restored to the #1 Production and Production 10-Client rankings.

TIFF 2025 opens with Turturro's analog pickpocket comedy 'The Only Living Pickpocket in New York'

The Toronto International Film Festival kicked off its annual lineup, featuring new work from Takashi Miike, Ryûsuke Hamaguchi, Werner Herzog, and a four-hour Elon Musk documentary. Among the festival's early standouts is 'The Only Living Pickpocket in New York,' starring John Turturro as an aging, technophobic thief navigating a city that has moved on to smartphones. The film hits theaters October 30th.

Brazilian physicist validates the physics behind Star Trek's Picard Maneuver

Physicist Níckolas de Aguiar Alves of the Federal University of ABC revisited the 'Picard Maneuver' from Star Trek: The Next Generation's episode 'The Battle,' in which Captain Picard jumps to warp speed and stops abruptly to create a visual double image that confuses an enemy ship. Working through the relativistic math, he found the tactic holds up better than the show's writers likely realized, tying it to real physics involving objects moving faster than a medium's speed of light.
