My car Toyota Prius accident happened 2 weeks from now

To raise awareness about the seriousness of car accidents, I'm currently considering writing a blog about this incident!

I still don't dare to drive up to Kiely Blvd. Some car accident syndromes!

On Tuesday, June 16, 2026, at around 6:25 PM, 2 cars collision occurred near Kiely Blvd. and El Sobrante St.

My car Toyota Prius was traveling south on Kiely Boulevard when a Toyota Camry with license plate number 5VMCO41, driven by Mr. L???? R???? Lopez, one of (qualitasins.com) insured individuals, struck my car's driver-side front wheel and door. His vehicle may have been traveling north on the left turn or from El Sobrante St. crossing Kiely Boulevard.

My automobile was driven by the incident to crash into a corner lot's front yard bush. Fortunately, the bush and the wood street sign stopped my car before it could crash into the house's wall.


Note:
   It is not sufficient to attach the insurance approval certificate to your car. Additionally, you require the paid renewal online packing slip, which is the car license plate approval paperwork.

Unable to run DSM7.3 bootloader after upgraded from 7.2 to 7.3

手賤升級到DSM7.3,啟動不了了(更新後無法執行 DSM7.3)

重新編譯引導(loader)啟動後無法開啟 DSM7.2 IP:5000(IP 無法訪問,或者 https://finds.synology.com 也無法查找到設備)

Panic!!!

Solution:
Downgrade(降級) from DSM7.3 to DSM7.1(42962)
=====================================
The trade off is loosing the system setup, but data file are still kept.
Why?
Because that if you choose to keep system and file both option, it will prompt "Failed to install DSM, Available system space is insufficient". So, the only option is to select "to keep file only" option.

Q: Why DSM7.1 and not the DSM7.2?
A: 需要半白才能安裝?

On Proxmox IP:8006 portal:
====================
To VM Shell: >> hp103 >> >_Shell
qm importdisk 100 /var/lib/vz/template/iso/rr.img local-lvm
#Assume that the VM for the NAS/DSM is on ID:100
Run the VM ID#100
Open the VM console >> menu.sh

>> Advanced option >> a: Allow downgrade installation
>> Select model >> ...
>> Select version >> DSM7.1
>> Select recompile the loader
>> reboot

Source:
======
Download the latest loader image: https://github.com/RROrg/rr
Upload the rr.img to local-lvm >> run qm command to make it as SATA0 as 1st bootable drive.

How to solve the 3x3 Rubik's Cube?

The accompanying screenshot, which shows the layer 2 and layer 3 solutions, does not include the first layer completion since it is assumed that you are aware of how to do it.

Notice:
The Chinese character "前" is equivalent to "Front" in English. It indicates that the cube on the "Front" side is facing you.

How to Create a MacOS Bootable USB

 Q: How to create a MacOS bootable USB in order to boot it up while press "Option" key on booting MacBook?

A:  Please use an MacOS MacBook to create it.
FYI. The TransMac software created on Windows OS won't work since it created as no bootable USB drive!!!

Here is the creation information:
=======================

Please download  MacOS_version.DMG file to a MacBook >> double click on the .DMG >> double click the Install MacOS.pkg >> It will install into Application folder >> using Terminal command with sudo to write the installer into USB drive.

(Some cases that there is no Install MacOS.pkg after double click on the MacOS_version.DMG, it will open with Installer MacOS.app, in such case, just drag & drop it into Application folder)

Here is the list of sudo command URL: https://support.apple.com/en-gb/101578

There is no list of command for Yosemite, here is the command:

sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ Yosemite.app
