sc被穿後，換sp又被穿

 

上圖是從https://steadyoptions.com/articles/the-options-wheel-strategy-wheel-trade-explained-r632/ 抓來的。

這就是目前小台搭配選擇權的策略。

一開始先小台+sc，第一二周沒穿價，收sc權利金，第三周被穿進結算賣了小台，整體是獲利。

第四周就sp，結果兩天就被穿價，所以平倉sp，再次買進小台+sc，又回到covered call。

sp被穿價要平掉真的有點想凹，但還是有確實執行，一切就照著策略走。

期貨賠 選擇權賠 那就混在一起做小台covered call

 雖然期貨做了6~7年， 選擇權也做了2年，都找不到穩定獲利的策略，但還是想做呀。

後來看了輝哥的covered call策略，解釋的內容比其他的介紹好很多。

即然看好台股長期是向上，那持有台指期也是很合理的策略，只要保證金放的夠多，搭配賣call來收權利金，的確是個很好的搭配。

目前就是小台搭配週選賣call，雖然小台是跌的，但保證金放的夠，賣call又一直能補點血回來，心裡的負擔感覺好多了。

希望這招能穩穩的做下去。

i-ctrl AC 使用心得

 

一開始連線設定好難用，跟ipcam這種產品相比，設定的順暢度差很多。

一次只能對應到"一種搖控器"，所以如果你有多台相同型號的冷氣，買一顆就可以同時控制這些冷氣。但如果冷氣是用不同搖控器，那一顆i-ctrl ac一次就只能控制一台。

連上冷氣後，不代表什麼功能都可以設定，連上10幾年的老冷氣後，只有開跟關的功能，溫度，冷氣或送風那些通通都不能用，也看不出來當下的冷氣是開還關。

只能在相同的區網內才能控制，官網上顯示的你離開會幫你關，回家可以先開，是透過手機GPS定位來判斷你的位置，並不是真正的你在外面用手機網路時，可以連線回來控制你的冷氣。

心得就是跟當初想要的功能差很多。

win10安裝framework3.5

最近win10下載framework3.5安裝時，一直失敗，都是在下載必要原件的地方失敗，改機碼也沒用。

後來看到一招，就是找一個win server2012以上的安裝iso，把裡面的sxs資料夾複製到win10的c槽，然後用powershell執行下列指令，就成功了。

dism.exe /online /enable-feature /featurename:netfx3 /Source:c:\sxs

Recently, I kept failing to install Framework 3.5 on Windows 10. The failure always occurred at the stage of downloading the necessary components, and modifying the registry didn't help.

Later, I found a method that worked. You need to find an installation ISO for Windows Server 2012 or later, copy the "sxs" folder from the ISO to the C drive of your Windows 10 machine, and then execute the following powershell command. This solved the problem:

dism.exe /online /enable-feature /featurename:netfx3 /Source:c:\sxs

EPSON無線投影

 EPSON買一些投影機有內建無線投影功能，有分成兩種投影模式。

1- screen mirroring

這種方式投影很簡單，投影機本身不需做任何設定，client電腦，win10以上，按下win + p鍵，就可以找到"連接到無線顯示器"的選項，選下去後，就會搜尋到投影機，直接進行連接投影，非常方便。

2- iProjection

這個就要先在投影機上，設定連上內部的無線網路。

然後client電腦要裝Epson 的iProjection 無線投影軟體。

client電腦跟投影機都在同一個區網內，iProjection程式執行後，就會自動搜尋到投影機讓你連線投影。

新買的asus 筆電安裝win10找不到硬碟

 新買的asus 筆電是win11，要重灌在win10。

但在安裝的過程，卻找不到任何硬碟(裡面有1個m.2跟1個sata硬碟)。

這時就要進到bios裡，在"進階"設定中，找到"儲存介面"，裡通換sata操作設定值，把raid改成ahci，重新再試一次，就可以找到裡面所有的硬碟了。

The newly purchased ASUS laptop came with Windows 11, but I need to reinstall it with Windows 10.

However, during the installation process, I couldn't find any hard drives (there is one M.2 and one SATA hard drive inside).

To solve this, I had to enter the BIOS, navigate to the "Advanced" settings, find "Storage Interface," and change the SATA operation setting from RAID to AHCI. After doing this and trying again, all the hard drives were detected.

新買的asus 筆電找不到secure boot選項

 新買的asus win11筆電需要降級裝win10，插入安裝win10的usb，就會出現"secure boot violation invalid signature detected. check secure boot policy in setup"的錯誤。

看到這個就是去bios把secure boot的功能關掉就對了，但進到bios裡，卻一直找不到。

後來才查到，要先把fast boot的功能關閉，secure boot的選項才會出現。

The newly purchased ASUS Win11 laptop needs to be downgraded to install Win10. When inserting the Win10 installation USB, an error message "secure boot violation invalid signature detected. Check secure boot policy in setup" appears.

To resolve this, you need to disable the secure boot feature in the BIOS. However, upon entering the BIOS, the option was not found.

Later it was discovered that the fast boot feature needs to be disabled first for the secure boot option to appear.

win10電腦麥克風沒反應 收不到音

某台asus win10的筆電內建麥克風跟外接耳麥，都收不到音。

但在裝置管理員裡都有找到設備，所以就更新驅動，結果還是沒用。

後來拿閒置硬碟換上去裝了win11後，居然都沒問題，那表示硬體沒故障。

在換回win10 後，突然想到，去設定裡面看看，結果發現在"隱私權"裡面有一個"麥克風"的設定，有一個"存取此裝置的麥克風"居然是關閉的，改成開啟後，麥克風就正常了。

An ASUS laptop running Windows 10 had issues with both the built-in microphone and external headset not picking up any sound. Even though the devices were detected in the Device Manager, updating the drivers didn't solve the problem.

Later, when a spare hard drive was installed and Windows 11 was installed on it, surprisingly, there were no issues with the microphone. This suggested that there was no hardware fault.

Upon reverting back to Windows 10, checked the settings. It was discovered that under "Privacy," there was a setting for "Microphone," and the option to "Allow apps to access your microphone" was inexplicably turned off. After toggling it on, the microphone started working properly again.

所有網路共用資料夾都連不上 錯誤代碼:0x80004005

 有台win7電腦有時後會突然連不到所有的共用資料夾都連不上 ，錯誤代碼都是0x80004005。

但上網都正常，去ping那些共用資料夾的主機也正常。

經查才發現，那個win7電腦的網卡內容裡，少了很多項目，正常的應該要像下圖一樣，但那台電腦裡的網卡內容只剩ipv4的設定。

要把其他功能找回來，就只要按下左下方的"安裝"，裡面就有其他項目可以選，選好後馬上就會裝回來了，但是要重開機後，會生效。

Sometimes a Windows 7 computer suddenly cannot connect to any shared folders, and the error code is always 0x80004005.

However, internet browsing works fine, and pinging the hosts of those shared folders also works.

Upon investigation, it was found that many items were missing from the network card settings of that Windows 7 computer. Normally, it should look like the image below, but the network card settings on that computer only have IPv4 configuration.

To restore the missing functionality, simply click on "Install" at the bottom left, where there are other items to select. After selecting the desired items, they will be installed immediately, but a reboot is required for the changes to take effect.

outlook 自動儲存尚未傳送的郵件

有的使用者不知是不是信件開太多，pst又掛載一大堆，三不五時outlook就會突然都沒反應，雖然從工作管理員查看，cpu還是有在處理，但每封信或是outlook主視窗上面所有的鈕都無反應，只能強制關係。

這時後如果有些信寫到一半還沒寄出會存成草稿，就會怕資料不見。 

outlook裡面有一個自動存到草稿的功能，就在"選項"-->"郵件"裡面，可以設定幾分鐘內沒寄出的信自動儲存。

如果是正常方式關閉outlook，系統會問你，要不要存，你選擇不存，就算超過設定的時間，也不會存到草稿。

但若不小心outlook當掉，超過時間的那些信，其實就可直接在開啟outlook後在草稿匣內找到，這功能還蠻實用的。
