7Americans no longer see four-year college degrees as worth the cost
- A new NBC News poll shows nearly two-thirds of Americans now believe a four-year college degree isn't worth the cost, a dramatic shift from 2013 when 53% said it was worthwhile. Rising tuition costs, student debt burdens, and graduates struggling to find jobs that justify their educational expenses are driving this sentiment change across all demographics, with Republicans showing the steepest decline in support for higher education value.
Higher education as historical accident
Higher education evolved from aristocrat finishing schools into job training centers, similar to employer-based healthcare. This mismatch between liberal arts origins and vocational demands has created a bloated, expensive system that poorly serves both educational and career preparation goals.College cost vs. value proposition
Rising costs ($100k/year at some schools) combined with uncertain job prospects make college's ROI questionable. While statistics show college graduates earn more long-term, immediate financial burden and risk of failure concern many families considering the investment.Educational credentialism vs. actual learning
Students increasingly view college as credential acquisition rather than education, leading to grade inflation and minimal effort. This "sheepskin effect" reduces actual learning while employers still rely on degrees as hiring filters.
8Iceland declares ocean-current instability a national security risk
- Iceland has designated the potential collapse of the Atlantic Meridional Overturning Circulation (AMOC) as a national security threat, marking the first time a climate impact has received this designation. The AMOC is a crucial ocean current system that keeps Iceland's climate relatively mild, but scientists warn it could collapse this century due to global warming, potentially surrounding Iceland with sea ice and causing catastrophic global weather changes.
Potential impacts of AMOC collapse
Discussion of how Atlantic current shutdown would dramatically cool Northern Europe (UK becoming like Labrador, glaciers in France/Germany) while making Caribbean/Florida much hotter with stronger hurricanes. Iceland might fare better due to volcanic heat.Timeline and probability of collapse
Debate over IPCC's "unlikely but not impossible" assessment versus newer research suggesting higher probability and potential collapse between 2025-2095. Comments note IPCC has historically underestimated climate impacts.Government response and political challenges
Discussion of Iceland taking it seriously as national security issue while other countries remain oblivious. Comments express pessimism about global action given political resistance and economic priorities over climate concerns.
9Windows drive letters are not limited to A-Z
- This article explores how Windows drive letters work under the hood, revealing that any single character can function as a drive letter, not just A-Z. The author demonstrates creating drives like +:\ and €:\ using the subst command, explaining that drive letters are essentially symbolic links in the Windows Object Manager that get converted from Win32 paths to NT namespace paths. While cmd.exe handles these non-traditional drive letters normally, applications like File Explorer and PowerShell specifically restrict themselves to A-Z drives, and the system can even handle non-ASCII Unicode characters as drive letters with some limitations.
Non-standard drive letters in Windows
Windows can use non-ASCII characters like € or λ as drive letters through NT kernel features, though they don't appear in File Explorer. This works because drive letters are just DOS compatibility conventions mapped to NT paths like \??\C:\foo.Windows backward compatibility vs Unix filesystem heritage
Discussion of Windows maintaining 1980s DOS drive letter conventions for compatibility versus Unix systems keeping 1970s filesystem hierarchy. Both systems retain legacy structures, with Windows prioritizing running old software.Windows mount points and NTFS features
Windows supports mounting partitions to folders like Unix using PowerShell Add-PartitionAccessPath or Disk Management GUI. Also covers NTFS alternate data streams, symbolic links, and other advanced filesystem features for malware evasion or system administration.
10Be Like Clippy
- The "Be Like Clippy" movement calls for companies to adopt more user-friendly data practices like Microsoft's old assistant Clippy, who helped users without exploiting their data. It encourages people to protest big tech's data exploitation by setting Clippy profile pictures and demanding transparency.
Clippy as an inappropriate mascot
Users strongly criticize using Clippy to represent anti-data harvesting values, arguing it was universally hated, intrusive, and monitored user actions. Many see it as fundamentally incompatible with privacy advocacy since Clippy embodied hostile, interruptive software design.Clippy's historical context vs modern comparison
Debate centers on whether Clippy's lack of data collection was due to technological limitations or genuine user focus. Supporters argue the comparison highlights how modern software prioritizes corporate interests over user experience, while critics call this revisionist.Hacker News community identity
Discussion about whether HN represents true hacker culture or has become dominated by "product-oriented engineers" and startup interests. Users debate the forum's relationship to anti-establishment movements versus Silicon Valley establishment values.
