Students are being prepared for jobs that no longer exist. Here’s how that could change.
NBC關於美國高中教育的深入報導, 提到現在的教育方式已經無法保證讓學生找到理想的工作,尤其是技職生. 文中提到几個點:

  1. 高中準時畢業的人有84%, 後來70%直升大學.
  2. 雖然學校盡力教導讓學生面對未來, 但學校也不知將來會是如何, 因為計劃跟不上變化. “We’re preparing kids for these jobs of tomorrow, but we really don’t even know what they are,”
  3. 2016年的調查, 只有34%的高中生(12th-graders) 對學習感到興趣.
  4. 公立大學(University of Massachusetts Lowell)1年的學費大約37萬台幣($12,496USD), 私立大學(Elmhurst College)學費約140萬台幣($47,121USD), 另一所公立大學(University of Minnesota)學費約91萬台幣($30,514USD). 另外自己查了一下哈佛大學每年學費138萬台幣(46,340USD), 以上都是只有學費, 如果加上宿舍及雜費大約是202萬台幣($67,580USD).
  5. 至2017年底美國的學貸已高達1.38兆美元, 房貸8.88兆美元, 信用卡債8340億美元. 53%大學生有學貸. Ref: https://www.newyorkfed.org/newsevents/news/research/2018/rp180213
  6. 醫護助理平均年薪67萬台幣($22,600USD), 2017年金融保險業年薪中位數約306萬台幣($102,510), 科技業約303萬台幣($101,430), 政府單位約295萬台幣($98,830), 所有職業中位數約113萬台幣($37,690). Ref: https://www.bls.gov/ooh/math/actuaries.htm#tab-5

讀書心得#

  • 如將mali gup dirver編成kernel module, gator無法支援gpu profiling, 是因為kernel 3.15-rc1for_each_kernel_tracepoint 只能找到built-in tracepoints. 如要找module裡的tracepoints 需要使用register_tracepoint_module_notifierunregister_tracepoint_module_notifier, 這樣的好處是縮小kernel image size, 及module loaded後才會做profile. 這個問題存在gator 5.x版, 後來在v6.1(Dec. 2016)已修正問題
    kernel-4.1, gatorv5.22 (2016/1/19)
#if LINUX_VERSION_CODE >= KERNEL_VERSION(3, 15, 0)
    /* scan kernel built in tracepoints */
    for_each_kernel_tracepoint(gator_save_tracepoint, NULL);
    /* register for notification of new tracepoint modules */
    register_tracepoint_module_notifier(&tracepoint_notifier_block);
#endif

kernel tracepoints have become unregisterable from modules as of 3.15-rc1
