It is the time of year when a lot of people in certain parts of the world carve pumpkins. [Gonkee] is carving a watermelon, which we assume is similar. He decided to make a CNC machine to do the carving for him. The unusual part is the use of two lazy Susans to make a rotary carving machine. You can see the result in the video below.

The hardware is clever and there is software that lets you do drawings, although we were hoping for something that would process gcode or slice STL. That would be a worthy add-on project. There were a few iterations required before the Melon Carver 3000 worked satisfactorily. Seeing a carving tool operating on two circles gives us a lot of ideas. We aren’t sure how sturdy the mounts are, so don’t plan on carving aluminum without some changes, but we suspect it is possible.

Then again, a laser head mounted on the frame would have probably made short work of the melon, and wouldn’t require much mechanical stiffness. It would, however, take a little effort to keep it in focus. So many ideas to try!

Watermelon is a popular hacking medium, apparently. There’s even one that holds a GameBoy.

Game company 2K has warned users to remain on the lookout for suspicious activity across their accounts following a breach last month that allowed a threat actor to obtain email addresses, names, and other sensitive information provided to 2K's support team. From a report: The breach occurred on September 19, when the threat actor illegally obtained system credentials belonging to a vendor 2K uses to run its help desk platform. 2K warned users a day later that the threat actor used unauthorized access to send some users emails that contained malicious links. The company warned users not to open any emails sent by its online support address or click on any links in them. If users already clicked on links, 2K urged them to change all passwords stored in their browsers. On Thursday, after an outside party completed a forensic investigation, 2K sent an unknown number of users an email warning them that the threat actor was able to obtain some of the personal information they supplied to help desk personnel.

President Biden on Thursday announced that he is pardoning all prior federal offenses of simple marijuana possession and encouraged state governors to do the same for state offenses. He also directed federal officials to review how marijuana is classified under the Controlled Substances Act.

"There are thousands of people who have prior federal convictions for marijuana possession, who may be denied employment, housing, or educational opportunities as a result," Biden said in a statement. "My action will help relieve the collateral consequences arising from these convictions."

The blazing announcement means that all prior charges, convictions, and not-yet-prosecuted offenses will be pardoned. The Justice Department will set up an administrative process for those affected to obtain a certificate of pardon.

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.

This is a very important first step into ‘normal’ computing for RISC-V, but availability and pricing are, for now, major barriers here. I’d love to get my hands on one of these, but at these prices, that’s a massive ask.

Shortages for lots of tech components, including things like DDR5 and GPUs, have eased quite a bit since the beginning of 2022, and prices have managed to go down as availability improves. But that reprieve hasn't come for hobbyists hoping to get a Raspberry Pi, which remains as hard to buy today as it was a year ago.

The most recent update on the situation comes from Raspberry Pi founder Eben Upton via YouTuber Jeff Geerling—Upton told Geerling that Pi boards are subject to the same supply constraints since the last time he wrote a post about the situation in April. Around 400,000 Pi boards are still produced per month, and some of these are being earmarked to be sent out to consumer retail sites. But Upton says that most of these are still being reserved for and sold to commercial customers who rely on Pi boards to run their businesses.

In short, the update is that there is no update. Upton said in April (and nearly a year ago, when the company raised the price for a Pi board for the first time) that the Broadcom processors at the heart of older Pi boards have been particularly difficult to source, but that high demand had been just as big an issue. Demand for Pi boards increased during the pandemic, and there was no more manufacturing capacity available to meet this demand. Upton said a year ago that there were "early signs that the supply chain situation is starting to ease," but backed-up demand could still explain the short supply even if the Pi's components have gotten easier to buy.
