  • Except maybe some devices (like IoT) that are powered up by an always plugged micro-usb, my cellphone is USB-C for a long time now, and my laptop has 3 USB-C/TB (no A), so it’s easier for a couple of stuff. But I have a usb-c hub with multiple USB-A outlet because I still have a couple of devices to plug like keyboard, trackball, webcam, headset, UPS, FTDI stuff, etc.

    No more micro-USB plugging/unplugging for phones.

    The prob with usb-c is mainly for powering hungry devices, you need 60W cable, 100W cable, 240W cable, etc.


  • REGULATIONS

    Returning to the U.S.

    Less than 48 hours in Canada:

    $200 USD worth of goods per person, tax and duty freeAny purchase of alcohol or tobacco products may be subject to duties and taxes

    48+ hours in Canada:

    $800 USD worth of goods per person, tax and duty freePurchases may include 1 litre of alcohol, 200 cigarettes (1 carton), and 100 cigarsFamily members can combine their tax and duty allowances



  • It looks like Trump still got ~70 millions vote, like before, but Harris got 66M while Biden got 81M, so the problem looks like Democrats failed to get people to vote.

    Maybe because Democrats were often lefties, workers, unionized, lower salary, lower education, etc, and they do not recognize themselves anymore in the Democratic party.

    We had the same things in France with the “gauche caviar”, basically the “caviar left”, all traditional factories workers who voted Socialist for decades, didn’t recognized themselves in this caviar left so voted elsewhere like right-wing, go figure…



  • Yes, I used a hardware KVM with a laptop (Dell with a dock) and a desktop, it makes a lot of wires, but it works. You may need a high end KVM if you want to switch dual-monitor, 4K+ monitor, etc

    But having both system at the same time is a must, so at one point I used RDP (windows->linux or linux->windows) from a screen.

    But for ~3 years now I’m using a software “KM”, meaning my desktop is connected to a monitor, my laptop is connected to the second monitor, and I share the keyboard/mouse (hence KM) in software using InputLeap (formerly Barrier). It is seriously pretty good, when my mouse exit monitor #1, it enters monitor #2, and whatever you type is entered in the system where your mouse cursor is. It is fantastic, I cannot live without this now.



  • Now that we have BLE (Bluetooth Low Energy) I’m pretty sure it is better than USB dongle. I have a BLE keyboard and a BLE trackball and never used the dongle so not sure how to compare.

    Plus it saves 2 USB outlets on my PC :)

    chatGPT says:

    Bluetooth Low Energy (BLE) typically offers better power efficiency than USB dongles for keyboards and mice, especially when both are battery-powered.
    
    Here’s how BLE compares to USB dongles in terms of power consumption for these devices:
    
    Power Efficiency:
        BLE is designed specifically to use minimal power, especially in low-data-transfer devices like keyboards and mice. It uses an efficient sleep-wake cycle and keeps the radio off most of the time, which conserves energy.
        USB wireless dongles, while not as power-hungry as other wireless technologies, are usually less efficient than BLE because they often keep a more consistent connection with the device.
    
    Battery Life:
        BLE devices typically offer longer battery life. A BLE-enabled keyboard or mouse can last from months to even a year or more on a single charge or set of batteries, depending on usage and the device’s power management.
        USB wireless peripherals, in contrast, may require more frequent charging or battery changes, although they are still relatively efficient.
    
    Sleep and Wake Latency:
        BLE is optimized to quickly reconnect after sleep, so devices wake up quickly with minimal delay. Some USB wireless devices can also wake fast, but the energy consumption during idle periods is generally higher.
    
    Compatibility and Usage:
        BLE is widely supported on modern devices (laptops, tablets, smartphones) without needing a USB port. USB dongles, however, need a USB-A or USB-C port (with an adapter) and are mostly used with PCs.
    
    In general, BLE is better for devices where power consumption is critical, like battery-operated keyboards and mice. However, for some gaming or high-precision tasks, USB dongles may offer lower latency, which some users prioritize over battery life.
