We had a problem that the year “2001” was automatically converted to “⑳01” when we input the year “2001” in the date of birth input form, and the form could not be inputted. We have solved the problem.

cause

Because a dictionary that converts “1” to “①” was registered in the user dictionary of the iPhone.

This will prevent the word from being converted without your permission.

Microsoft Visual Studio 2019 and Microsoft Visual Studio 202 appear to have an issue where Visual Studio cannot be installed in an offline environment.

To determine the cause of the error, you need to refer to the logs output in the TEMP folder.

Checking the error log, the Visual Studo installer is terminating due to “0x138b”.

According to the Developer Community, with the new certificate revocation checks added after late June 2025, the following installers cannot access the revocation server in an offline environment and the installer is aborted.

Countermeasures

To install on an offline computer, the following intermediate certificate must be installed

Microsoft Windows Code Signing PCA 2024.crt (Microsoft official)

Microsoft Windows Code Signing PCA 2024.crt (Techlog Mirror)

After installing the certificate, the installer will start as usual.

A problem with BUFFALO Wi-Fi access points not outputting wireless (Wi-Fi) when connected to a hub with Cisco PoE functionality.

When checked on BUFFALO’s web management screen, the message “Invalid because PoE is 802.3af” is displayed.

Or, the DIAG light blinks red four times each and wireless (Wi-Fi) is not output.

Cause

In order for BUFFALO Wi-Fi access points to operate via PoE, they must be powered by the IEEE802.1at standard from the hub, but by default, they are only powered by the IEEE802.1af standard from the Cisco hub.

When Wi-Fi access points and hubs negotiate standards for power supply on both sides, Cisco products use a proprietary standard called CDP (Cisco Discovery Protocol).

BUFFALO products do not support CDP (Cisco Discovery Protocol), but only the standard protocol LLDP (Link Layer Discovery Protocol), which prevents communication using the appropriate standard.

Countermeasures

If you want to continue to use the Cisco hub, you need to enable LLDP on the hub’s console.

enable
Switch# configure terminal
Switch(config)# lldp run
Switch(config)# end
Switch# write memory

This completes the process.

The status of the PoE power supply can be checked with the following command.

I was using Tailscale’s Exit node on a Linode (Akamai Cloud) VPS for fixed IP purposes,

The new node that we started to build around mid-2024 was not able to connect to the Internet.

Coping Methods

Select “Ubuntu 20.04 LTS” as the OS when creating the VPS.

In checking Tailscale defects (Issues), it has been reported that it worked correctly at least on Ubuntu 21.04 and earlier.

Selecting “Ubuntu 20.04 LTS” as the closest version on Linode will solve the problem for now.

I had forgotten to configure the Firewall settings, which resulted in a large number of unauthorized access attempts.

Since I was so busy, I decided to compile a list of which user names and from which countries there were a large number of attempts.

Is there something wrong with the audio from the speakers at karaoke, or might they not be outputting from either side? When you feel that the sound is not being output from either of the speakers, you can check the speakers by making the following reservations using the remote control function.

By selecting the song above, you can check the speaker output.

If sound is not being output from either speaker, or if the phase setting is incorrect, ask the front desk staff to check.

Karaoke allows you to set the background music volume, microphone volume, echo level, etc. There is a way to return all these settings to their default values.

By performing the above operation, all changed settings can be returned to the default values.

If you wish to return to the default settings when you leave the store, you can do so by performing the above operation.

In Windows 11, by default, the setup cannot be completed in an offline environment because the specification now requires a Microsoft account.

By executing the following command during setup, the installation can be done offline.

cd oobe
> BypassNRO.cmd

After rebooting, proceed to the “Let’s connect to the network” screen, where you will see the text “You are not connected to the Internet” and can configure offline.
