Synology手動更新韌體失敗 更新檔毀損

 下載了synology的韌體更新檔後,要手動更新,結果都會跳出更新擋毀損的錯誤。

其原因是NAS主機上的韌體版本跟要更新的版本差太多,(要從6.3升到7.2)。

解決方法就是先去下載7.0.1版來手動升級,升級成功後,再手動升級最新版,就可以了。



After downloading the Synology firmware update file and attempting a manual update, an error message stating that the update file is corrupted always appears.


The reason for this is that the firmware version on the NAS is too far behind the version you're trying to update to (upgrading from 6.3 to 7.2).


The solution is to first download version 7.0.1 and manually upgrade to it. Once the upgrade is successful, you can then manually update to the latest version without issues.

主機板上的內建顯卡 抓不到螢幕

 有幾台同型號的桌機,主機板上有內hdmi/dvi 接孔,也都有加裝外接顯卡,螢幕接上外接顯卡都正常運作。

但把外接顯卡拔掉,螢幕接上內建的hdmi/dvi ,就都抓不到螢幕,到bios裡也找不到可以調整了。

去查了一下該主機的手冊才發現,原因主機板上有內建的顯示接孔,不一定有用,還要看cpu有沒有支援。

怎麼查cpu有沒有支援,可以查看這篇說明

https://www.asus.com/tw/support/faq/1045576/




There are several desktop computers of the same model. The motherboards have built-in HDMI/DVI ports, and they all have external graphics cards installed. When the monitor is connected to the external graphics card, everything works fine.

However, when the external graphics card is removed and the monitor is connected to the built-in HDMI/DVI ports, the screen is not detected, and there's no option in the BIOS to adjust it.

After checking the manual for the motherboard, I found out that even though the motherboard has built-in display ports, they may not be functional depending on whether the CPU supports it.

To find out if the CPU supports it, you can refer to this guide:

covered call 期貨一直跌 很煎熬

 最近一直跌,Sell call雖然都有賺到,但賺的部分實在很難補小台跌的部分。

真的是很煎熬,要一直補保證金,不然怕等等不小心被斷頭。

一直在想是不是應該買個PUT才對。

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.
