Unfortunately FMCW lidar is sweeping the lasers across the same band. You don’t need the exact frequency just a beat frequency that’s within your detection Bw. Also balanced detectors have something called common mode rejection. This is no

Unfortunately the gain falls as function of temperature so you also get a lot less light and you have to pump harder (more current). So while it’s possible to somewhat compensate somewhat with the mirrors the device still has this behavior

If the device is reliable then you should quote a FIT number. A very good VCSEL based transceiver in an indoor environment has a FIT of about 100 at Tj~65C and a CI of 60%. If we assume your FIT rate is similar (it won’t be because your o

The issue will not be at cold but at high temperature. VCSELs have very poor efficiency at high temperature and it’s possible to operate them where increasing current reduces light output. In a vehicle application the temperatures are ver

Imagine every car has a FMCW LIDAR. The chance of interference is very high. Additionally if those receivers are using SE PDs, then these sensors will also be “blinded” (TIAs and or PDs will saturate) when a nearby Lidar system shines i

Used to be a Microcenter in Santa Clara. It was a good store and huge. But it closed a few years back. At the time it seemed like it suffered from the same problem as Fry’s. Sounds like maybe they regrouped and are doing better now.

The future of these interconnects is to make them optical. Once the interconnects are optical lots of problems get solved. Chips don’t have to be in same enclosure, simplifying cooking etc.

Having worked in a large company that is famous for its feedback culture, I think the type of feedback culture you refer to is hard to scale. While I think it helps people improve, I’ve mostly seen how feedback is used to hurt people.

What’s great is that their actual landing page has a section that says inspired by inventors.

Imagine how different the world would be had he gone home instead. Kind of blows my mind to think about.

I’ve always associated all caps with shouting. Not sure how an all caps logo with a few softening tweaks sends a message of empathy.

I’m not Indian but I love “do the needful”. I’ve only ever encountered it when people used it for humorous affect. Something about it makes me smile.

It’s funny how these modern companies are rediscovering the old rules for behavior. When I was young it was a given that you didn’t discuss politics, religion, etc...

I’ve always read that binary systems seem to be the norm and stars like our Sun the exception. Is it possible stars like our Sun form from binary protostars that form too close together and collide to form a single star? Or do we have ple

The implicit assumption here is that you can always change jobs. That’s not true if the economy is bad. We now have a generation of people in the workforce that have not seen a downturn. Back in 2001-2003, I was locked into a startup t

Yet another reason not to have so much concentration in a single person. If we had smaller or more distributed social networks it would be impossible to control the spread of E2E encryption.

Sorry but I don’t agree this is a bug. You need to decode your bytes to properly write a string. Otherwise you get the unexpected result you are showing because it has no way of knowing how your bytes are encoded.

This is a cool article. It raises all kinds of interesting questions. I’ve often wondered if it’s possible to have consciousness as we experience it without language. When I think, I do so in words so I can’t imagine how I would do that

Most people get paid electronically. A lot of things people don’t realize is that at 330M+ people, the US has a lot of legacy systems due to the sheer size of the population.

Anyone know if this technology works? Sounds a bit too good to be true.

I am as American as they come but wealth as reported by this article is a false metric. The Swiss have an amazingly high quality of life and standard of living. For most Americans, I don’t think our quality of life is anywhere near what i

The cost of installation is why I don’t have solar. While I agree 25 year life is a limitation on adopting better panel technology, it’s hard to justify the installation costs at shorter intervals.

Maybe if you had the money to grow up with a computer and had people around to help you. I didn’t program until 1991 in Turbo Pascal. It was a terrible experience and somehow it was something you were supposed to already know. On the Va

I had my first major career failure this year and lost a very good job. I was able to land another good job quickly but I’ve been full of doubt and am seriously lacking in confidence ever since. I can’t sleep and have anxiety. The new jo

I think so. I grew up surrounded by WW2 vets that had seen lots of combat and lived through the Great Depression. They were good men but they were pretty hardened people.

I don’t think the GP was implying that everyone gets severance. Generally employers are often in legal grey areas when they are letting people go; particularly in cases where there is no legal or policy violation. In these cases they of

I am into motorcycles and so there are plenty of forums for that. In the Bay Area we have 2 active forums. A problem is that Facebook has eroded it a bit. I also mountain bike and there are also forums for that. One of my favorites is

This outage coincides with FBs PSC (performance summary cycle) time. I wonder if this is folks trying to push features so they get “impact” for PSC.
