Asked 144 people a question ‘What is the most exciting trend in technology for you in next 15 years?’. Got amazing answers. There were many standard ones like ‘AI and Cryptocurrencies’. Most interesting responses started with ‘I am not real

Those two are not mutually exclusive.

One thing to note. While biogenic and thus "green", the methane is about 30 times as potent greenhouse gas (over 100 years), so we can not consider pure "carbon footprint" here. There are similar problems with restoring

This is true. High efficiency and low carbon emission are not always in the same boat.

It is possible to do it "the hard way". In 2012/2013 I consulted on power consumption measurement of one communications app where separate measuring jigs were built for iPhone 5. Little bit of custom electronics and automatio

Even more efficient is to control the flow in a hydroelectric plant by stopping the generation when the demand is low. This removes the cost of pumping. If there is sufficient reserve water capacity it is done in places where the energy pri

The pressure was probably from the ISP side. This is easy to make for the ISP, just one extra line in the request for tender. For IoT devices it is harder to push through, there are no real incentives to spend on security except the potenti

My sources say that his Roadster is already orbiting the sun. Mars would be a new thing. If this fails it will still be orbiting the sun, but as a distributed cluster this time.

Here (in Estonia) the pricing changes every full hour. We get pricing for the next day (24h) a day before by 14 (2 pm). This is calculated from weather forecast, expected consumption and available generation resources. This is for residenti

Honda hybrids have mechanical CVT. Except the new Accord, which has no gearbox and uses electric drivetrain for slow speeds and direct engine coupling for highway.

Faster response time in motor control, high torque in low revs. Makes math simpler.

Not confusing. It is so much easier to make electric vehicles self-driving compared to the ICE vehicles. It may be economically feasible to do so in not so distant future. Real estate, including parking spaces is expensive. There was a good

I drive a hybrid with CVT. After getting used to its smoothness driving with a "normal gearbox" feels really awkward.

Why can't your (or shared) car go and charge itself while you are not using it?

I think it is worth to mention that their team at UNSW is hiring and has PhD scholarships available. About 30 positions are open. I am not affiliated them, but noticed the listings at http://www.cqc2t.org/employment

If it runs on a standard 9V battery, then a very good option! Newer and smarter smoke detector chips are designed for 3V lithium-manganese dioxide batteries.

In theory, you can. However, the standards also mandate that the "annoying" function has to work at least few months after the battery is low. Adding an extra LED there will consume too much power.
409.
by IndrekR 9y ago
(Un)fortunately there are things that are written down in standards, like the LED blinking behavior, that the manufacturers can not change if they want to legally sell the devices. You can get a smoke alarm with 10 year battery life to redu

To me (an electronics engineer) it sounds like your neighbor's alarm did not pass EMC immunity tests quite ok... and at the same time the car's tests were passed with way too thin margin. Or it could be that one of the alarm input

The contrary is also true. We can think about lot more than we just sense.

I have discovered two compiler bugs that got fixed after reporting them. In both cases it was relatively new implementation at the time (TI C55x in CCS and TI MSP430 in IAR). In both cases the compiler generated wrong assembly code. This al

Yes, the Infineon case. Gemalto uses their chips. One interesting thing. As Gemalto was the first frontier, the stock market reacted quickly to them (-25%). However, the Infineon stock went to the other direction (+27%) since the vulnerabil

If you go fishing, you should cut the hook off the line before you cast. Otherwise getting the fish may ruin the fishing. Unfortunately some people think along the same line about running a company, not necessarily a startup one. Oh, and if

What about the right to repair our software? Running a electronics engineering house here and we can easily see 9:1 ratio of software:hardware people-time ratio in bringing a device to the market. Varies heavily from project to project, but

Yes there is a reason. It is called safety. There is a big difference in making a battery in phone safe to handle and separate stand-alone battery safe to handle. This includes things like puncture resistance, heat dissipation, vibration an

Is it removed or moved? Social networks so far are between humans. Removal is bad, categorization to 2..3 subgroups may be good. I guess this is what they are testing.

To an outside observer (I do not have a FB account), this looks like a good plan from the FB side. Kind of like GMail inbox categories/tabs. All about reducing the signal (friends) to noise (something you may have liked 3 years ago) ra

Reminds me the story of reintroducing wolves to Yellowstone [1]. Imapact was relatively large to the whole ecosystem with many unexpected surprises, mostly positive. [1] https://www.yellowstonepark.com/things-to-do/wolf
