Tech Bytes: Twitter’s whistleblower, Roku is revamping, Samsung’s huge gaming monitor

Twitter’s whistleblower heads to Washington. The company’s former security chief goes before a senate panel today. In July, Peter Zatko claimed Twitter prioritized user growth over privacy and security. Twitter says the allegations lack context.

Roku is revamping its most affordable streaming device. The company is upgrading its “Roku Express” which comes with dual band WiFi for the same price of $29.99. The company also introduced a $130 subwoofer called the Roku Wireless Base, both items are available for preorder.

Finally, Samsung’s enormous new gaming monitor, the “Odyssey Ark” is now on sale.
The 55-inch curved, and rotating, ark debuted in January at the “consumer electronics show”.
The ark comes with a 35-hundred dollar price tag.
