  • The smartphone with convenience and control

    I often hear people saying that they have nothing to hide, and I usually reply that it is not about what you want to hide, it is about what you want to protect – your family’s privacy. Modern smartphones are convenience, always on and connected, but they come with a large attack surface to be exploited by hackers or even spying companies.

    [...]

    Purism believes building the Librem 5 is just one step on the road to launching a digital rights movement, where we—the-people stand up for our digital rights, where we place the control of your data and your family’s data back where it belongs: in your own hands.

  • Allwinner V831 AI Full HD Camera SoC Powers Sochip V831 Development Board

    In the last year or so, we’ve started to see several camera SoCs with a built-in NPU or SIMD instructions to accelerate face detection, objects detection and so on, starting with the low-resolution Kendryte K210 processor to the 2.5K Ingenic T31 MIPS video processor, or even the 4K capable iCatch V37 camera SoC.

  • Rockchip RK3588 8K TV Box Triples as 5G & WiFi 6 Router, Home Automation Gateway

    Rockchip RK3588 octa-core Cortex-A76/A55 processor was only expected in the second half of 2020 for IoT and vision/AI applications, but at least one company is working on a 3-in-1 product based on Rockchip high-end processor with a “5G AIoT 8K TV box” that also works as a 5G and WiFi 6, and with features such as Zigbee can also act as a home automation gateway.

    [...]

    The thing is supposed to run Android 9.0 operating system, but it’s a little odd that Rockchip does not work on an Android 10 for an upcoming processor.

  • Simplify data visualization in Python with Plotly

    Plotly is a plotting ecosystem that allows you to make plots in Python, as well as JavaScript and R. In this series of articles, I'm focusing on plotting with Python libraries.

  • Perl Hacks, Perl School, and the future of Perl publishing

    Dave Cross, long-time Perl user, trainer, and author, recently released The Best of Perl Hacks, a curated collection of his best posts from his Perl Hacks blog. His imprint, Perl School, has published six e-books, including two that I wrote. There’s an unrelated book, Perl Hacks: Tips & Tools For Programming, Debugging, And Surviving, by chromatic, Damian Conway, and Curtis “Ovid” Poe. It’s also very good, but completely separate from Dave’s.

  • Qt for Automation changed to Qt M2M Protocols

    Qt M2M Protocols is now automatically included for free to every new Qt Device Creation subscription. The additional distribution license price has been removed as well. Qt Application Development license holders can buy Qt M2M Protocols separately.

  • Using Visual Studio Code for Qt Applications – Part Two

    In the last blog post we saw an essential, C++ oriented, Visual Studio Code setup. That was enough to get going right away, but we can still definitely do more and better. Here I’ll show you how to get a complete setup for your qmake and CMake projects, all this while also wearing a Qt hat (on top of my C++ hat) and having a deeper look at the Qt side. Build qmake Qt projects Qmake is not integrated with Visual Studio Code the way CMake is, so setting up a qmake project for build is slightly more convoluted than doing the same with CMake. This means we’ll have to define our own build tasks. We’re going to do this in two stages: build steps definition and build steps combination, leveraging the fact that Visual Studio Code implements task dependencies and ordered sequential execution of dependencies.

  • Where Did Software Go Wrong?

    Computers were supposed to be “a bicycle for our minds”, machines that operated faster than the speed of thought. And if the computer was a bicycle for the mind, then the plural form of computer, Internet, was a “new home of Mind.” The Internet was a fantastic assemblage of all the world’s knowledge, and it was a bastion of freedom that would make time, space, and geopolitics irrelevant. Ignorance, authoritarianism, and scarcity would be relics of the meatspace past.

    Things didn’t quite turn out that way. The magic disappeared and our optimism has since faded. Our websites are slow and insecure; our startups are creepy and unprofitable; our president Tweets hate speech; we don’t trust our social media apps, webcams, or voting machines. And in the era of coronavirus quarantining, we’re realizing just how inadequate the Internet turned out to be as a home of Mind. Where did it all go wrong?

  • good idea bad implementation crosstalk

    Unfortunately products like the latter seem quite common. Most things in my house are still rather dumb because regrettably few products are actually the same thing, but smarter. Instead smart devices are inevitably some inscrutable machine intelligence physically manifested in my house. So no thanks. Battle lines drawn, everybody pick a side, good idea or bad implementation, and fight!

Ryzen 9 3900X/3950X vs. Core i9 10900K In 380+ Benchmarks

Following our initial Core i5 10600K and Core i9 10900K Linux benchmarks last week, here is a much larger comparison I have been working on since then in looking specifically at the Ryzen 9 3900X and 3950X against the Core i9 10900K. It's the largest to date with nearly 400 benchmarks being tested, most of them real-world test cases. The past number of days I have been running this Core i9 10900K vs. Ryzen 9 3900X vs. Ryzen 9 3950X comparison with 381 benchmarks out of 138 distinct applications/workloads on both systems. With this round of benchmarking the Gigabyte Z490 AORUS MASTER and ASUS ROG CROSSHAIR VIII HERO were at play with 2 x 8GB DDR4-3600 Corsair memory, Samsung 970 EVO NVMe SSD, and Radeon RX 5700 XT graphics. Benchmarking was run off Ubuntu 20.04 LTS while upgrading to the Linux 5.7 Git kernel for the very latest kernel bits. All other Ubuntu 20.04 packages were at their respective defaults. Read more

Compact 8K video encoder runs Linux on Kaby Lake

Advantech has launched a “VEGA-8300E 8K Broadcast Video Encoder” and streaming appliance for 8Kp60, 10-bit 4:2:2 HEVC real-time encoding. The system runs Ubuntu on a 7th Gen Kaby Lake CPU and offers 2x hot-swappable SATA bays. We realize that most of you are not in the market for an 8K video encoder, but we occasionally like to check in on the high-end video world where Linux is steadily making inroads. Normally Advantech’s VEGA-8300E 8K Broadcast Video Encoder would have been showcased at the NAB Show, which has been cancelled due to the pandemic. (Some NAB content is available on the online NAB Show Express.) We heard about the VEGA-8300E from an Advantech announcement on Businesswire that revealed the product has won a 2020 Best of Show Special Edition Award presented by TV Technology. Read more
