Perhaps because Intel realized their new products weren’t selling, the Core Ultra 200S series CPUs have seen significant price cuts. I took the opportunity to build a new PC with an Intel Core Ultra 7 265K, temporarily using the integrated graphics. While the Core Ultra 200S isn’t great for gaming performance (especially online games), forContinue reading “Fixing Ultra 7 265K’s Frequent Stuttering”

I recently got a new phone and installed Smart AutoClicker to automatically click the skip button while idling in single-player games. However, on the accessibility settings page, I couldn’t grant the clicker permission. I tried using an adb command (adb shell settings put secure enabled_accessibility_services …), but it still didn’t work. After checking logcat, IContinue reading “Enables Accessibility Features for Sideloaded Apps on Android 15”

BBR is a TCP congestion control algorithm developed by Google. It improves upon the shortcomings of traditional congestion control algorithms (like CUBIC), which reduce speed upon packet loss, significantly enhancing bandwidth utilization in high packet loss environments. It’s important to note that congestion control algorithms manage the packet sending rate. For example, if a GoogleContinue reading “Enable TCP BBR v2 on Linux & Windows 11”

Installing ESXi on an unsupported device is a matter of luck. Unfortunately, I found that my computer’s built-in NIC is a Realtek R8168 — a network card no longer supported by ESXi. In the ESXi 6.x era, we could add the net55-r8168 driver to make ESXi support this NIC, but after ESXi 7.x disabled allContinue reading “ESXi 7.0 + R8168 / R8169 Installation Notes”

Telegram claims to have 5 data centers (DCs), referred to as DC1~5 in Telegram’s code and documentation. Among them, DC1 and DC3 are located in Miami, USA; DC2 and DC4 are in Amsterdam, Netherlands; and DC5 is in Singapore. Each account is associated with a DC upon registration and does not change with the user’sContinue reading “Mysteries of Telegram DC”

Windows 11 has significantly improved the touchscreen experience and added support for native Android emulation, making me want to try a touch-enabled Windows 2-in-1 device again. Coinciding with the release of the Surface Pro 8, this model ditches the 6-year-old thick-bezel design, featuring a 13” 120Hz high-refresh-rate screen and Intel’s most powerful integrated graphics, IrisContinue reading “Optimizing my Surface Pro 8”

I encountered a strange issue recently—after upgrading to Windows 11, the option to change the default opening method for formats like .jpg, .png, etc., in the settings became grayed out and unusable. It was impossible to change the default image viewer, forcing the use of Windows’ default Photos app. However, on another Windows 11 computer,Continue reading “Fix for Windows 11 Unable to Change Default File Opening Method”

After the dream of “building a high-performance PC” gradually faded, I used my original budget to purchase a PS5 and an Xbox Series X. In media reviews, they are considered the most powerful consoles of this generation, both supporting HDMI 2.1 4K 120Hz and being quieter than their predecessors. However, after hands-on experience for aContinue reading “PS5 Vs. Xbox Series X”
