The context was a person who insisted the number of people alive today was more than all who had ever lived. The statement felt wrong but I also initially didn’t believe 100B. After some research, I now believe the 100B number is about

Even more sobering is to consider how many people who have ever lived. The number is estimated to be ~100B people. I was so blown away by this number when I learned it that it affected me for several days after. I often consider it when

As much as we all love to blame HR it is unfair to put this on HR. The hiring manager writes the job description and comes up with the requirements. In many cases these job descriptions are written by a senior IC and the hiring manager ju

Here’s a good explanation on the differences modern concrete and Roman concrete. It turns out they are pretty different materials. https://www.sciencealert.com/why-2-000-year-old-roman-concre...

Are you familiar with the concept of hyperbole? A hyperbole is an exaggerated statement or claim not meant to be taken literally.

It seems like most social media platforms are hazardous to your health and livelihood and there’s very little upside to voicing your opinions.

Shouldn’t the benefit of all our technology be the gaining of time for leisure and non-work pursuits?

Sorry HW engineer here and I strongly disagree. You don’t ship hardware like this. 122F is only 50C. Most components can handle 85C so shutting down at 50C means the thermal rise is >35C. This is simply poor design.

In Kip Thorne’s book about Interstellar he talks about what they had to do to make something that would work for a movie. They had to choose a specific mass and rotation speed that doesn’t really exist in nature or the image would not be s

Not sure where everyone is getting their numbers but the failure rate for manned launches over the last 20 years is 0.8%. The percentage chance of death while climbing Everest is around 1%. SpaceX’s Falcon has ~2% failure rate. Unmanned

This phrase seems like a WW2 reference as Voronezh was the site of a great battle. Care to elaborate on the context/origin?

In the US, it can take either meaning depending on context/inflection/delivery.

Real Genius was great. Are there any other movies about graduate school? I can’t think of any.

I would add The Right Stuff to this list; it inspired me to study physics. Edit: Others have mentioned Real Genius which I thought was also cool as a kid.

As a resident of California, I would greatly prefer fewer people. Losing population isn’t necessarily something negative in my opinion.

I don’t know any chip manufacturers that shutdown due to COVID. Everyone has been shipping the entire time and fabs are at capacity. The way chip manufacturing works is that you get a slot and if you cancel they fill your slot with somet

This is not really true. Firstly, the volume for automotive is much higher. 2nd the cost structure is entirely different and a business set up for high cost low volume military parts may not be competitive in automotive with low cost.

Automotive is actually quite reliable and military spec parts are often automotive rated parts that have additional testing and/or slightly different packaging. The military has been using automotive grade parts to reduce costs where p

The challenge with automotive parts is reliability and performance over extended temperature and humidity range. This is not necessarily something you are just good at because you already produce semis.

In theory yes. For example, certain optical elements perform Fourier transforms. However optical computing as we know it today is really a type of analog computer. Today’s optical devices are relatively large compared to transistors so

Matrix multiplication. They use a cascaded Mach-Zhender MEMs array as their systolic matrix multiplier. These types of schemes are limited to the amount of loss that they have. Additionally since these are analog components they have a c

The latency at this scale of the device is largely irrelevant as it would be dominated by FEC. The PN junctions themselves have BW of about 25GHz, well above anything compute is doing.

Many others have been shipping SiP in higher density for much longer. Acacia and Luxtera (both acquired by Cisco) for example.

We have enough consolidation. I’d like to see more diversity than 4 tech companies owning absolutely everything.

I am not sure the lead-acid battery is a good analog. Lead acid batteries are very simple constructions and therefore easy to recycle. There is also economic incentive to recycle an old battery core as you get a lower price on a new batt

I think you bring up a good point about auto recycling generally. There is a large industry in the US that recycles cars and car parts. About 80% of a car can be recycled. I wonder how the move to electric vehicles will impact a car’s o

Apple and Huawei were typically TSMC’s biggest customers and both those companies have been on the bleeding edge driving process technology (typically adopting the new node 1 year before everyone else). With the Huawei ban, it’s unclear if
