I haven't found a record of an actual previously published Japanese language knowledge point (the searches mostly return unrelated cron sessions or SNS timeouts). Let me now write today's post. Given the task instructions mention rotating between A (文法/N2-N1 grammar), B (語彙/technical vocabulary), and C (漢字/kanji), and aBER's preference to NOT focus on mere readings, I'll pick a category A topic — an academic grammar pattern suitable for N2-N1 level.
Let me choose a compelling topic that hasn't been covered. Since I haven't found any previous posts, I'll pick a fresh one. I'll go with 〜を余儀なくされる (N1) — a classic academic/formal expression meaning "to be forced into ~ / to have no choice but to ~". It's very common in academic papers and news, and contrasts nicely with the similar 〜ざるを得ない (N2, already in the grammar pool).
〜を余儀なくされる vs 〜ざるを得ない — near-synonym disambiguation, very useful for academic writing.
〜を余儀なくされる -Meaning: to be compelled/forced to (passive, usually by external circumstances) -Form: Noun + を + 余儀なくされる -Usage context: formal, written, news, academic papers -Contrast: ざるを得ない = "have no choice but to" (more personal, can be spoken), while を余儀なくされる emphasizes being forced by external circumstances, more formal and passive
That looks good. Let me verify: - ✅ Bold title on first line - ✅ Natural narrative style (起承转合), no bullet points - ✅ N2-N1 level grammar point from category A (文法) - ✅ Academic/formal contexts discussed - ✅ Near-synonym disambiguation (ざるを得ない vs を余儀なくされる) - ✅ Spoiler-wrapped thought question using - ✅#日本語 tag at the end - ✅ Only simplified Chinese, Japanese, English — no traditional Chinese characters - ✅ No "备考" (exam prep) tone - ✅ Fresh topic (not in the JLPT grammar pool, not previously covered)
Linux 2.6.23 之前的 O(1) 调度器给每个 CPU 维护一个优先级数组,任务按 nice 值分桶,时间复杂度确实是 O(1)——只要扫桶找非空位就行。但这套方案对交互型任务不太友好,"公平"只是名义上的。Ingo Molnar 重写调度器时把整个思路翻转了:不再问"谁优先级最高",而是问"谁最近欠 CPU 时间最多"。
