TV and set top box testing is shared between our partners (manufacturers and operators) and Netflix. Our partners must run our test suite before submitting for certification. We don't have all the devices under active testing all the t

Yes. This was the only TV device on L. It was already 2 years old at this point, which for pure Android TV would not be allowed by Google. Since this was an AOSP device, the operator could stay on an older version.

The handler always copies the same amount of data. It has to be called more often to copy a lot of data, which is what usually happens when Android buffer isn't full. I agree with you that this isn't usually how this is done. Doin

The "buffering" parts of the graph show the "fill the buffer" behavior described in (3). The time between calls is very short and large amounts of data are moved.

Are you talking about Atom or XScale? XScale seems the biggest missed opportunity. I can understand the thinking that being just another ARM vendor was a step down from being the owner of an architecture (AMD, and Via, notwithstanding). But

This isn't explicitly related, but interesting, so I offer it up here. When I read 40ms, it triggered a memory from tracking down a different 40ms latency bug a few years ago. I work on the Netflix app for set top boxes, and a particul

You make a good point, but in a monolithic kernel the kernel is the “safe place.” Most likely the effect of this would be subtle and not necessarily long lived.

This sounds familiar. Around 2002 I bricked a Pentium motherboard while probing the SPI address space looking for the fan and temperature sensors.

Invisibilia just released a great podcast about trust, based on the experience of a trader who was harassed by Wirecard. The trader, who was shorting Wirecard, was subject to surveillance, and a constant stream of phishing attacks. https:&

I admire Armstrong for taking the time to write such a thoughtful letter. With the exception of people who are close to me, I usually calculate that it's not worth my time to engage and try to refute a conspiracy theory.

Yes, that's correct. There is no mechanism to restrict all internal travel, no federal power to stop people from traveling between states. The FAA can ground flights and stop trains. The various state police forces can set up road bloc

Back in 2002 I wrote a documentation templating system in m4. It provided a lot of the same tags as markdown, and generated HTML. In retrospect I have no idea why I wrote it in m4 - I think it was a "because I can" kind of thing.

This happens on set top boxes, especially when the graphics memory heap is allocated separately from the system memory heap. The graphics memory heap can be fragmented and surfaces stop being rendered because there are no contiguous memory
