Ubuntu Pro becomes free for individuals and small companies

Ubuntu Pro Free

Canonical has launched free Ubuntu Pro subscriptions for individuals and small companies for up to five machines, enabling anybody to get longer-term support and features that were only reserved to paying enterprise customers so far. Canonical provides Ubuntu for free with LTS versions released every two years and supported for 5 years. The latest Ubuntu 22.04 LTS was released in April 2022, meaning it will be supported until April 2027. But if you’d like to get 10-year support and extra security features you can now do it for free through an Ubuntu Pro subscription for up to 5 machines. Let’s compare the key differences between Ubuntu LTS and Ubuntu Pro first. You’ll get 10 years of support instead of 5 with Ubuntu Pro and as well as improved security. If you are upgrading to the latest LTS soon after it is out, the 10-year support may not be worth much […]

Allwinner V851S/V851SE low-cost camera SoC embeds 64MB DDR2, a 0.5 TOPS NPU

Allwinner V851S/V851SE is a single-core Arm Cortex-A7 SoC with a RISC-V core, an H.265/H.264 video encoder, and a 0.5 TOPS NPU designed for Smart IP cameras with support for features such as human detection and crossing alarms. Both processors ship with 64MB DDR2 memory, and feature USB, Ethernet, and SDIO interfaces, but the V851S is designed for systems with a display, while the V851SE targets traditional headless IP cameras. Both processors are pretty similar, but here are the key differences between Allwinner V851S: Networking – 10/100 Mbps Ethernet port with RMII interface GPIO – 6x ports (PA, PC, PD, PE, PF, PH) Display LCD Parallel RGB, Serial RGB, i8080, BT656 2-lane MIPI DSI SPI – 4x SPI and Allwinner V851SE: Networking – SIP 100 Mbps EPHY GPIO – 5x ports (PA, PC, PE, PF, PH) Display – Not supported SPI – 3x SPI That means the Allwinner V851S requires an […]


Unexpected Maker TinyS3, FeatherS3 and ProS3 boards feature ESP32-S3 dual-core wireless MCU

The BBC has released a new web-based Python editor for the micro:bit board

There are already Python editors such as Thonny, but the BBC thought those were not good enough and released a new web-based Python editor specifically designed for the micro:bit education board targeting 11 to 14 years old pupils. The micro:bit Python editor includes drag and drop code examples, code structure & error highlighting, auto-complete feature, a simulator to test the code before uploading it to the micro:bit board, and a Quick ideas section to help pupils get started with projects. The BBC’s micro:bit Python editor works with both the micro:bit V1 and V2, but note the simulator shows a micro:bit V2, so if you are using the previous generation micro:bit, some code may work on the simulator but not on your micro:bit V2 board. For that reason, the BBC marked the code that only works on a micro:bit V2 with ‘V2’ in the Reference section.  While the BCC is a […]


Alibaba T-Head TH1520 RISC-V processor to power the ROMA laptop

The ROMA RISC-V laptop was announced this summer with an unnamed RISC-V processor with GPU and NPU. We now know it will be the Alibaba T-Head TH1520 quad-core Xuantie C910 processor clocked at up to 2.5GHz with a 4 TOPS NPU, and support for 64-bit DDR at up 4266 MT. The TH1520 is born out of the Wujian 600 platform unveiled by Alibaba in August 2022, and is capable of running desktop-level applications such as Firefox browser and LibreOffice office suite on OpenAnolis open-source Linux-based operating system launched by Alibaba in 2020. So that means we now have a better idea of the specifications of the ROMA RISC-V developer laptop: SoC – Alibaba T-Head quad-core RISC-V Xuantie C910  processor @ 2.5 GHz, unnamed Imagination GPU for graphics, 4 TOPS NPU for AI System Memory – Up to 16GB LPDDR4/LPDDR4X RAM Storage – Up to 256GB eMMC flash Display – 14.1-inch […]
