How to Verify SHA256 Checksum of File in Linux using sha256sum

The last week I intend to install Red Hat on my System. I was able to download and create a bootable device using the dd command without any hassle. If you know, Red Hat has options to Test media & Install Red Hat Enterprises, so I have selected those options; while it’s verifying media, it shows the error of The file header checksum does not match computed checksum.

• Arduino Blog » Monitor your hoverboard’s power draw with this Arduino-based meter/logger

  If you look at your car’s dashboard, there’s a good chance you’ll find an efficiency rating for how you’re driving. However, what if you instead ride a hoverboard? This functionality is certainly not stock equipment, yet Niklas Roy wanted to understand the power consumption of his transporter during different riding situations. For that reason, he decided to develop a power monitor that not only graphs his stats when scooting around, but records the data for later viewing and analysis. Roy’s handheld device is controlled by an Arduino Nano and utilizes a Hall effect ammeter for current sensing. The measurements are shown as numbers and as oscillograms on a 1.8” TFT screen, which can also be logged to the display’s built-in SD card. An RTC module provides timestamp information for these readings, which can be produced using Processing and overlaid on video.

• STM32U5 Cortex-M33 MCU gets more performance, 2D graphics accelerator, and advanced security

  The new family has a higher 160 MHz clock speed, up to 2048 KB flash, up to 786 KB RAM, a 2D graphics accelerator, several peripherals have been upgraded, and a new autonomous mode lets DMA and peripherals keep working while most of the device sleeps in order to save power. [...] The board also comes with 512-Mbit octal-SPI Flash memory, 64-Mbit octal-SPI PSRAM, 256-Kbit I2C EEPROM, as well as ARDUINO Uno V3, STMod+, and Pmod expansion connectors, plus an expansion connector for a camera module, and STLink-V3E embedded debugger.

Documentation Improvements in KDE

Doxyqml, our documentation bridge between QML and doxygen, got various improvements, thanks to Olaf Mandel and Lasse Lopperi. Now QML enums are supported and the lexer/parser got various bug fixes. Speaking of QML documentation, the Kirigami API documentation was improved and now uses more correctly @inherit tags and @property tags. There is still room for improvements, but the current state is already a lot better. Most Components are now showing all their properties correctly and the type of the property is correct. (kirigami!239) Another improvement is that the generated Kirigami documentation now shows more accurate names: e.g. Kirigami.Page instead of org::kde::kirigami::Page. This makes it easier to read and navigate the documentation. There was also a bit of background work inside KApiDox, Jannet added support for QDoc, allowing to use QDoc as an alternative to Doxygen. This might be a better solution for generating documentation for projects with a lot of QML. Also: MJ Inventory Released
