Home flippers see smallest profits since the Great Recession, real estate data firm says The typical home flip netted investors just $65,981 in gross profit last year, or a 25.5% return on investment, according to real estate data provider ATTOM.

Douglas Todd: Everybody loves their entitlements, especially B.C. housing developers Councils have approved 132,000 housing units that developers haven't started to build. Money can be made by monetizing such 'entitlements'.

瀏覽器崩潰不見得是軟體的錯！Mozilla 發現高達 15% 的 Firefox 當機源自記憶體「位元翻轉」 * * Mozilla 資深工程師 Gabriele Svelto 近日分析約 47 萬筆自動提交的當機報告，得出令人驚訝的結論：10%~15% Firefox 當機並非軟體程式碼錯誤，而是硬體層面的「位元翻轉」（Bit flipping）導致。 所謂位元翻轉，是指記憶體單元數值無任何軟體操作，卻自己從0變成1或從1變成0。這發現遠超過之前所有相關估計，Svelto也坦承這數值之高「令人瞠目結舌」。造成位元翻轉的主要因素有： * 宇宙輻射：高能粒子穿透設備，撞擊RAM的奈米電容導致電荷洩漏。 * 熱效應：高溫環境記憶體穩定性下降。 * 電壓不穩：電源供應不穩定影響記憶體運作。 * 製造缺陷：記憶體晶片本身品質問題。 * 元件老化：長期使用後硬體退化。 且位元翻轉的發生率也會跟著環境劇烈變化，這也解釋了為何太空設備必須使用經過抗輻射強化的特殊元件： * 地面環境：每年約一次因位元翻轉導致當機。 * 飛機高度：宇宙射線暴露量增加300倍。 * 太空環境：暴露量增加1,000倍。 Mozilla團隊開發了當機後自動執行的記憶體測試工具，能在瀏覽器崩潰後掃描記憶體傾印檔，尋找單位元損壞的特徵模式：單位元指標錯誤、損壞的哨兵值（Sentinel Values）、堆疊損壞；而關鍵數據統計顯示： * 確認的位元翻轉當機率：約5% * 估計的位元翻轉當機率：約10% * 排除記憶體不足後比例：高達15% * 源自真正硬體問題比例：約50% 然而，由於測試工具僅檢測最多1GB記憶體且運行時間不超過3秒，實際數字可能更高。 ### ECC記憶體：解決方案為何難普及？ ECC（Error-Correcting Code）記憶體能有效解決位元翻轉問題。原理是以另外晶片儲存校驗位元，每次讀取時完整檢查，單位元錯誤時可自動修正，多位元錯誤時偵測並回報，防止無聲損壞。且ECC記憶體價格並不高昂，成本只增加10%~15%，影響效能低於2%，故伺服器採用率100%，消費級採用率卻不到5% 為何消費市場採用率如此低？Linux之父Linus Torvalds曾公開批評英特爾刻意將ECC支援限制在Xeon伺服器處理器，Core/i系列桌面處理器完全無法使用。這並非技術限制，而是為保護伺服器CPU利潤的市場區隔策略。AMD部分Ryzen處理器於特定主機板支援ECC記憶體，消費者可當成替代選擇。 ### 安全隱憂：從當機到攻擊手段 位元翻轉不僅是穩定性問題，更是安全漏洞。2015年Google Project Zero展示名為RowHammer的攻擊技術，反覆存取相鄰記憶體序列，利用DRAM物理特性誘發位元翻轉，成功提高x86-64 Linux系統核心權限。2022年的後續研究更令人擔憂：研究員使用「RowHammer Blacksmith」變種技術測試40款DDR4記憶體模組，結果全數均有漏洞，即便具備TRR（Target Row Refresh）防護機制也無法倖免。 使用者該如何防範？面對無法100%重現的隨機當機，Mozilla工程師建議深入除錯程式碼前，先排除硬體問題，先測試記憶體： 1. 下載MemTest86+（免費開源工具）。 2. 製作可開機USB隨身碟。 3. 用USB開機執行測試。 4. 建議至少執行8小時（可利用夜間進行）。 5. 發現錯誤→更換故障的記憶體模組。 零錯誤→可確認為軟體問題，繼續除錯。 工程師並建議以下幾項是降低風險的實用方法：**避免超頻** 。遊戲開發商ArenaNet研究發現，超頻的CPU和RAM與當機率呈正相關。**確保散熱良好** 。高溫會增加位元翻轉機率。**使用品質可靠的電源供應器** 。穩定供電有助減少記憶體錯誤。**考慮ECC記憶體** 。若使用AMD平台，可評估採用支援ECC的組合。 此研究在技術社群引起討論，部分開發者質疑：如果位元翻轉能損壞記憶體，是否也可能損壞當機遙測程式，導致誤判？也有人指出Chrome的當機頻率低於Firefox，究竟是Chrome錯誤處理機制更優秀，還是程式碼品質有差？ Svelto承認，10%~15%估算是基於損壞模式的「保守推斷」，而非絕對數值，確切數字仍有待更多研究。無論確定比例是5%、10%還是15%，核心訊息都很明確：並非所有當機都是軟體的錯。宇宙輻射、溫度、電壓波動和故障RAM都可能導致開發者無法用程式碼修復的當機。 Svelto也特別強調，這個問題不限PC。無論Mac、智慧手機、印表機還是路由器，任何內建記憶體的設備都可能受位元翻轉影響。從這個角度來看，能自行更換元件的PC組裝玩家反而處於較有利位置──至少不必因一條故障的記憶體而丟掉整台設備。 * Memory bit flips cause up to 15% of Firefox crashes, asserts Mozilla engineer — figure inferred from 470,000 auto-submitted crash reports * Firefox Crashes: 10% Are Bitflips, Not Software Bugs * 10% of Firefox crashes are caused by bitflips （首圖來源：Pixabay） 文章看完覺得有幫助，何不給我們一個鼓勵 請我們喝杯咖啡 ## 想請我們喝幾杯咖啡？ ### 每杯咖啡 65 元 x 1 x 3 x 5 x 您的咖啡贊助將是讓我們持續走下去的動力 **總金額共新臺幣 0 元** 《關於請喝咖啡的 Q & A》 ### 留給我們的話 取消 確認 從這裡可透過《Google 新聞》追蹤 TechNews * * * 科技新知，時時更新 科技新報粉絲團 加入好友 訂閱免費電子報 * * * 關鍵字: Bit flipping , bitflips , chrome , ECC , Firefox , 位元翻轉 , 瀏覽器 , 當機

"Whenever you have to make up your mind
But troubled you don’t have any
The simplest solution that I find
Is simply by #flipping a penny
No not that the fates decide your affair
While yer helplessly sitting there moping
But the moment the penny is up in the air
You’ll suddenly know what yer hoping."

Fucking people with moronic questions. The condition of the items I flip is always noted CLEARLY in the listing. People that ask too many fucking questions aren't worth the time. This item is less than half of retail- obviously they can inspect it at the exchange. I just block and move on. #Flipping
