With the price of RAM getting out of control, it might be a good idea to remind Linux users to enable ZRAM so they can get better performance without upgrading memory, or save money on their next single board computer by selecting a board with the right amount of memory.

I had already written about the subject when I enabled ZRAM on a ODROID-XU4Q in 2018 using zram-config, and did the same on my Ubuntu laptop at the time. In recent days, I found Firefox crashing often due to running out of memory on my system with 16GB of RAM, and the Linux 7.0 release reminded me about ZRAM, since there were some related changes. So I decided to check the current swap configuration on my Ubuntu 24.04 laptop:

Amazon has taken the wraps off a new Fire TV Stick HD that it says is its slimmest yet. At $34.99, the device offers a design that Amazon says is 30 percent thinner than the previous generation, along with the ability to power it directly through your TV’s USB port. The new design eliminates the […]

Adobe is fully embracing AI tools that enable creators to edit their work using descriptive prompts, instead of manually using specific Creative Cloud apps.

Upgrading your phone with a camera grip attachment is one thing. But doll-sized telephoto lenses that you mount on top of the rear camera C’mon. I wrote the Vivo X300 off as a gimmick, a funny concept designed to generate attention rather than actual sales. But then I spent a weekend carrying the phone and […]

It hasn’t been officially announced, but Walmart’s website now has a listing (you may need to set your location to Ventura, California) for an updated version of its budget-friendly Onn 4K Pro streaming box that originally debuted in May 2024.
