So, I don't have a source to back this up, and without a source this will be worst of the rumour mill, but I'll say it anyways in case someone has a source to back it up or refute it.
A few weeks ago it was explained that Facebook is telling affected people they are no longer on the team they were on before, and they have X weeks (4?) to apply internally and find a role on a new team. So you're not fired, you just don't have a team and failed to find a new one, so.. see ya?
This is extremely privileged advice, but the only thing I managed to do to help was to have a second place to go to where I didn't work - in my case a little cabin in the woods. Going there on the weekend forces me to take breaks. If I'm at home I'm working. It doesn't help that I'm a solo founder. Work is very rewarding but it can also be all consuming. And there my piano sits untouched.
I rewrote the main loop of this a few years ago to be re-entrant, so you can render N samples at a time. Synth projects wanting to use SAM should start somewhere like that probably.
Can you explain this more? I've been getting into home automation and my wife would like programmable irrigation for when we're not at home. Did you interface with existing wifi valves or are you doing the circuit yourself?
I recently got rtlsdr to read my water meter so I can detect leaks, which is pretty cool
What the OP did was build a simple irrigation controller for an existing irrigation system. Most irrigation systems use electronic solenoid valves that open when very low current 24 VAC power is applied to the two terminals.
Take a look at the Spec for a valve from Rainbird:
• Holding Current: 0.20 A (4.80 VA) at 60 Hz, 0.23 A (5.40 VA) at 50 Hz
If you have a sprinkler system, you can replace the on/off valve with a solenoid valve and then you're able to control the system electronically using a 24 VAC power supply and a switch. The OP replaced the switch with a relay, which is a switch that can be actuated by the lower voltage from something like a microcontroller.
12v valves off Amazon. Don't get the cheap plastic ones. Get the brass versions
as long as you don't run several at once, can power from old wall wart with a few amps rating. I'm using a meanwell PSU so I can power a few other things - IR lights mostly
When I learnt about how the Texas grid was a disconnected electrical island I thought maybe there is now a market to charge transport-trailer sized batteries out of state, drive them into Texas and drain them into the grid.
Texas grid is big enough to do fine on it's own. The problem is that power providers (and gas companies) are given the upper hand and never had to winterize more than a token amount, hence the house of cards came down last February and around 500 people died as a result. The Texas lege passed an "oops" bill that put on a couple bandaids, but the same thing is bound to happen again with the next big Freeze comes along.
All of crypto barely uses more power (120 TWh) than a single hydroelectric dam produces (111 TWh.) The "bad for the environment" is a meaningless talking point used by people that are jealous they didn't "get in on it" early enough.
Oh, it only requires ALL the energy from by far the largest and most environmentally destructive hydroelectric dam on the planet? One that accounts for 10% of China's energy use? Oh, that's nothing at all then! /s
How do guys like you keep a straight face saying things like this? This is an utterly insane amount of power. And putting into context the utility these crypto services are providing to most people (very little), it's even more insane. How much power would we be using if everyone actually started using PoW crypto for useful transactions regularly?
And it's not just electricity, it's high-end silicon too.
Cryptocurrencies is the first example of an algorithmic cancer IMO. (I cell that's tricking its host into thinking it's useful, but which mainly replicates and takes over resources as much as it can regardless of the utility the cells have to the host.)
Those numbers --- lower than numbers you can get from Google, but sure --- appear to say the same thing as "all of crypto uses barely more power than any but the top 28 energy-consuming countries in the world". Do let me know if I got the math wrong there!
Now you know that most most countries barely use any power! A single dam could power them! This is why the "crypto uses more power than X country" is a meaningless talking point.
The list includes Sweden, Norway, Argentina, the Netherlands, the UAE, the Philippines, Finland, Belgium, Pakistan, Austria, the Czech Republic, Israel, Switzerland, and Singapore, among (obviously) many others. I don't think that statistic was the mic drop you thought it was.
But sure, let's give them all 111TWh hydroelectric dams.
The Site C damn in British Columbia (5.1TWh) has been under construction since 2015 with a 2025 completion forecast. Estimated cost: $12.3 billion (USD).
>>> So let's use the article's figure of 140 TWh of power used per year. Let's compare that to domestic energy usage by country https://yearbook.enerdata.net/electricity/electricity-domest.... That's more than Argentina and about half of what the UK uses.
>> Bitcoin would be the 27th most energy using country: ahead of Argentina (30), Sweden (29), and Ukraine (28); just below and about to overtake Malaysia (26), and below Egypt (25) and Poland (24).
> A big chunk of our economy in Argentina is transforming sunlight into soybeans. So we should add it. Just imagine that we covered all the Pampa with solar panels and then use that energy to ... illuminate hydroponic soy.
> So with an additional energy of 36.5TWh, we jump from 132.7TWh to 169.2TWh that is more than the value of Poland 168.8TWh. (But other countries may want to add their solar->plants power too.)
The single largest hydropower dam in the fucking world could power them... I really don't think you know the scale of the power generation you are eluding to here, energy is a currency for development, there is nothing being developed in the real world with the amount of power that crypto uses. Absolutely nothing.
Compare the real-world value of economies powered by the energy consumption of crypto and let me know if you think that crypto is creating more value for humanity than these countries, I'd love to hear your arguments on that.
> The Hoover Dam generates, on average, about 4 billion kilowatt-hours (4 TWh) of hydroelectric power each year for use in Nevada, Arizona, and California - enough to serve 1.3 million people.
Edit: Looks like the "single hydroelectric plant" is the Three Gorges. Hot dam, that really puts Hoover to shame.
> The Three Gorges Dam has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012 (10% of China's electricity).
111TWh is well beyond a typical hydroelectric dam output (most are an order of magnitude lower storage and generation). As an example, the very sizable Australian Snowy Hydro 2.0 upon completion is estimated to have storage for 350GWh (the Australian national energy market is ~190TWh). The original Snowy Hydro (9 stations) has annual energy production of ~5GWh.
