In addition to the demand from AI data centres, I believe this also contributes to the high price. https://www.tomshardware.com/pc-components/ssds/intel-samsun...
iceboundrock··on Rating 26 years of Java changes
Primitive variables in Java, such as `int`, `boolean`, and `double`, store their actual values directly in memory. When they are local variables inside a method, this memory is typically allocated on the thread's stack. These primitives do not have the structure or overhead of an object, including the object header used by the Garbage Collector (GC) to manage heap-allocated objects.

If a primitive value must be treated as an object (e.g., when stored in a Java Collection like ArrayList or when passed to a method that requires an object), Java uses a process called `boxing` to wrap the primitive value into an instance of its corresponding Wrapper class (e.g., Integer, Boolean, Double). These Wrapper objects are allocated on the heap and do possess the necessary object header, making them subject to the GC's management.

It appears that most of the good changes are imported from C#.

iceboundrock··on So you wanna build an aging company
As a co-founder of Ginkgo Health[1], this is a refreshing discussion to see.

The "Is this aging?" article perfectly articulates the philosophy that drove us to start the company. We saw a huge disconnect between the longevity industry's focus on hype and moonshots, and what the science actually shows is effective for improving healthspan. The article's point about focusing on frailty and sarcopenia is spot-on ; functional health is one of the most powerful and evidence-based levers we have to improve quality of life as we age.

That's precisely why we built Ginkgo Active. We wanted to create a genuine "geroprotector" that was accessible to everyone, not just a theoretical treatment for the wealthy.

When we responded[2] to the recent CMS RFI[3] on the Health Technology Ecosystem, we outlined this exact approach. Our goal is to provide a practical solution to functional decline and chronic disease, which are massive burdens on the healthcare system.

Here’s how our thinking aligns with the article's main points:

Focus on Function, Not Just Biomarkers: Instead of chasing clocks, we focus on delivering personalized exercise prescriptions designed to improve strength, balance, and cardiovascular health. Our AI platform uses over 170,000 rules from authoritative sources like the American College of Sports Medicine to create these plans. Prevention and Healthspan: Our platform is built to help people before they get sick, preventing or delaying the onset of 18 different chronic condition risk factors. This is about adding healthy years to life, which is the core of a real aging intervention. Accessibility and Equity: We believe this kind of preventative care should be a right, not a privilege. We intentionally designed our platform so that it doesn't require expensive wearables or equipment. Our goal is to provide the same expert-level care to everyone, regardless of their income or where they live.

We believe the first real, scalable product of the longevity industry will be one that improves healthspan for the many. That's the problem we're dedicated to solving.
