Summary
Purism is offering a 5% bonus on investments for the next two months to advance their social purpose mission. However, the company’s claim to have the Librem 5 phone in stock by July seems unlikely, given the 52-week lead time disclosed on the company’s website. Additionally, the FAQ on the investment page is incomplete, omitting the fact that Purism had also conducted a similar convertible note offering in 2021, leading some to question the legitimacy of the investment opportunity.

Summary
The Xerox Palo Alto Research Center (PARC) was established to develop the “office of the future,” and computing professionals at PARC began to make purposeful copies to back up their work. They built a clone of a PDP-10 mainframe from Digital Equipment Corporation, called MAXC, and installed the TENEX operating system to back up their work.

Source: Pure: No more hard drives will be sold after 2028 – Blocks and Files
Summary
Pure Storage executive, Shawn Rosemarin, has predicted that hard disk drives (HDD) will not be sold after 2028 due to rising electricity costs and availability, as well as cost declines for NAND per terabyte. He argues that moving from spinning disk drives to flash memory could reduce power consumption by 80-90% while increasing density.

Source: Anatomy of a Drum Machine
Summary
The Delptronics LDB-1 Analog Drum Machine was designed to be small and inexpensive by paring down each instrument’s circuitry to its core and tuning the component values until it sounds perfect. The drum circuits in the LDB-1 are very similar to those used in classic analog drum machines.
Fact
🥁 The LDB-1 uses bridged t-networks to produce decaying sine waves, just like the TR-808 and many other classic drum machines, with the pulse provided by the microcontroller. The circuits for the bass, toms, and woodblock are identical except for the resistor and capacitor values.

Fact
Source: Qubits 30 meters apart used to confirm Einstein was wrong about quantum
Summary
Scientists have demonstrated that quantum mechanics breaks local realism, which is when two objects behave as one quantum system regardless of the distance between them. An experiment utilized superconducting qubits that were separated by enough distance so light could not travel during measurements. The qubits are also easy to control, providing new precision to measurements that could be crucial for future quantum computing efforts.
