Open system, private data.
It's not that other energy monitors are bad, but they are different in that they are mostly closed systems that provide limited data and require that you use their cloud and phone app platforms.  IoTaWatt collects many more metrics and stores that usage history locally.  With it's integrated web-server you can manage setup, view real-time status or create detailed graphs using the browser on your computer, tablet or phone. It's your data, in your own home, and subject only to your own privacy and retention policy. You don't need the cloud to get a handle on your hot-tub, EV, solar or heat-pump.

IoTaWatt can, however, easily upload usage data to any of several third party databases with associated apps and analytic tools.  For instance PVoutput is a free service that connects easily with IoTaWatt and provides world-class solar energy analytics. There is full support for uploading to influxDB.  There is also an API interface for those who want to query data for their own applications or to use in spreadsheets, and there are integrations available for home automation software like Home Assistant.

A universal solution.
IoTaWatt is probably the only monitor in it's class that can literally be used to monitor any power system.  It is in use in over 60 countries worldwide.  USA split-phase 120V/240V is easy, but also 230V single-phase as in Europe, 230V three-phase as in homes in Australia, Germany and norway to name a few. Most folks only care if it will work in their situation.  The answer is an unqualified yes.

There are also many commercial/industrial users monitoring high voltage three-phase systems including 277V/480V industrial with 600Amp service using several megaWatt-hours per day - more than most households use in a year.

The CEWs report referred to a CBS News investigation that exposed the fact that the ASPCA “raised more than $2 billion for animal welfare” in 2008. However, it only spent about seven percent of the money that was donated to local animal welfare organizations. The organization shelled out $421 million on fundraising. //

“Ever since the ASPCA began to aggressively fund-raise several years ago, humane societies and SPCAs throughout the country have suffered,” said Erica Gaudet Hughes, executive director of the State Human Association of California. “Our member humane societies and SPCAs frequently report hearing from people who gave to the ASPCA believing they were giving to their local shelter. These shelters believe they are missing out on funds that were intended for them.”

Admiral Rickover's 1953 paper reactors memo:

http://www.ecolo.org/documents/documents_in_english/Rickover.pdf

Still a classic.

Excerpt:

An academic reactor or reactor plant almost always has the following basic characteristics:

It is simple.
It is small.
It is cheap.
It is light.
It can be built very quickly.
It is very flexible in purpose (“omnibus reactor”)
Very little development is required. It will use mostly “off-the-shelf” components.
The reactor is in the study phase. It is not being built now.
On the other hand, a practical reactor plant can be distinguished by the following characteristics:

It is being built now.
It is behind schedule.
It is requiring an immense amount of development an apparently trivial items. Corrosion, in particular, is a problem.
It is very expensive.
It takes a long time to build because of the engineering development problems.
It is large.
It is heavy.
It is complicated.

That said, some PWR and BWR modular designs are very far along and should be started soon. //

One thing I keep in mind is that there's a few companies in the United States that install 3-4 reactors a year and generally on-time and under budget - General Dynamics Electric Boat Company, Huntington Ingalls Industries and Newport News Shipbuilding.

I'm introducing a Constitutional Amendment providing that U.S. Senators, like Members of the House, must always be elected rather than appointed.
5:42 PM · Apr 17, 2023

“Section 1. No person shall be a Senator from a state unless such person has been elected by the people thereof. When vacancies happen in the representation of any state in the Senate, the executive authority of such State shall issue writs of election to fill such vacancies.

“Section 2. This amendment shall not be so construed as to affect the election or term of any Senator chosen before it becomes valid as a part of the Constitution.” //

The repealing of the the 17th would make a whole lot of things better. The great Neal Borts use to say who represents your state in congress -- the answer was No one. //

And the 16th, while we are at it, concomitant with the adoption of The Fair Tax to be administered by the states and leaving the Federal government to collect taxes from the States rather than from the Citizens, obviating any need, whatsoever, for the IRS and the tax code that IT enforces. //

NO! We need an amendment to repeal the 17th amendment and return state representation to DC, not one to push us further away from the founders intent. State legislators select them. //

Get rid of the 17th Amendment, but modify the selection process for Senators. The reason the 17th Amendment was passed was because state legislatures couldn't agree on a Senator if the upper chamber and lower chamber were held by different parties. So, stipulate that each chamber appoints one Senator. If a vacancy occurs, the chamber in question can assemble to appoint a replacement. One six-year term and out.

While I am at it...I'm not a Warren Buffett fanboy, but he did have an idea that I would like to modify as follows. Since the House is responsible for initiating revenue bills, require that the House produce a balanced biennial budget on time (such that no continuing resolutions are needed). Failure to do so means that all current members of the House are ineligible to stand for re-election (in my world, that ineligibility would be permanent).

One last thing. Get rid of income withholding. Make people pay in quarterly. You'll see the biggest contraction of government in world history (idea courtesy of Rush Limbaugh). //

I like everything except disqualifying House members. Budget bills should be passed for each cabinet department individually (no omnibus bills), before the first day of the fiscal year. If not, the budget for the new year is automatically frozen at last year's level.

Ive made the full adoption to windows 11 and figured out how to work around their simplification of the OS.

For all you techies who want original control panel options in windows 11

right click on the option like devices and printers, then click on open in new window. Now you have the old interface for that tool in windows 11 like it was in windows 10.

I agree with the suggestion to have all four physical servers use your internet sources directly, preferably with default minimum and maximum poll intervals so the software can tune the poll intervals to the conditions as they change.

I also agree with creating a single domain name which has A/AAAA records for all four servers (one or the other, either 4 As or 4 AAAAs, as the clients should not treat the same server via IPv4 and IPv6 as distinct servers unless the network paths are actually distinct, which I doubt they are).

Further, I would suggest the four use each other as additional sources, using the same pool directive as the clients, e.g.

pool ntp.example.com iburst

They will refuse to use their own IP as a source and add the remaining three. Once all servers are referencing each other, I would also suggest enabling orphan mode. Just use “tos orphan 10” in ntp.conf to set the orphan stratum (higher than any normal stratum they operate at, low enough to avoid any downstream clients reaching stratum 15). In case your internet connection is lost, the four servers should then agree on one functioning server the remaining will sync to, providing a single freewheeling clock your entire network will use, rather than 4 different freewheeling clocks which would slowly diverge.

Thin brush head design, deep into cracks is no longer difficult. Makes it easier to clean any gaps, corners, narrow space or cracks in the room.

Crevice design can easily reach into the gap and clean. Two pieces of fabric are clipped together, which is perfect for cleaning the sliding track.

Small enough to get into the gaps of many hard-to-reach corners. Perfect for removing grease & dirt from window grooves, blinds, air vents, sliding doors for shower, doors, etc.

It's a bad idea due to one and only one reason:
Solid/liquid radioactive waste pollution stream
We have no where to put that crap!

Do you think this is an issue which is merely not presently solved, or one which cannot be solved?
Do you reject all options that have wastes?
Do you oppose the development of kinds of nuclear which could consume the spent fuel we already have?
If waste is contained, is it really pollution?
If there are fission products we can find uses for, would those still count as waste?

We did launch nuclear power before we had a real plan for what to do with the spent fuel, but because we didn't wait we also got some benefits, like:
nearly 2 million people avoided choking deaths, millions more avoided serious illness, many hundreds of billions in health care costs were avoided; around 60 billion tons of CO2 were displaced, thousands of tons of mercury and other heavy metal poisons were not released; and our power plants gave us the means to destroy the fuel from 20,000 nuclear warheads. And in exchange for all those benefits, we now have some spent fuel which has never killed anyone. Do you feel that was a bad trade? //

Fusion plants may be practical for several reasons.

They can help displace coal and natural gas faster than just building wind and solar.

Let's check that, shall we?

Right now, the US has approximately 360 coal-fired plants with a total nominal capacity of 260 GW. And in this year alone, there will be about 27 GW of solar or wind power added to the US grid. So, even if the pace of solar and wind power plant building doesn't increase (and there is every reason to think that it will), renewables will be able to completely replace coal in under a decade.

Any bets on fusion being ready for commercial-style plants in a decade?

There is roughly three times as much power produced from natural gas-fired plants in the US, so it would take another three decades at the current rate of adoption for solar and wind to replace natural gas.

Will fusion be ready in four decades? Maybe?

Should we keep researching into fusion power? Heck, yeah. If nothing else, fusion is the best way to move around the solar system. But count on it as an alternative to solar and wind? Heck, no. Not unless there are a lot of advances in a very short time - but I wouldn't bet on that happening.

From that article:
Microsoft says that Insider Program PCs that didn't meet Windows 11's minimum requirements "had 52% more kernel mode crashes" than PCs that did and that "devices that do meet the system requirements had a 99.8% crash-free experience."

So... 0.2% experienced crashes. 52% more is 0.3%. So 99.7% had a crash-free experience without the new features. I suspect it's mostly about locking everything down. Heck, looking at StatCounter's Windows version stats the share of Win7 only fell below 10% in 2023 even though support ended in 2020. Use of Win11 is only 20% today. Clearly nobody's rushing to get a new OS.

The problem for Microsoft is that they have nowhere to grow. Apple's M-chip computers are selling well. For the younger generation smartphones/tablets are their default. They have the business and gaming markets, but those are already saturated. But if they think they can increase the revenue through OEM fees by forcing a premature upgrade of non-obsolete hardware, I think they're really miscalculating.

People will simply not upgrade. Best case nothing happens from running unsupported and they don't get any money, worst case some bad exploits and bad PR. Apple must be loving that, if they can avoid pricing their entry level products out of the market they'll grab another big chunk of ex-Windows customers. And Linux is an okay desktop these days too, if you don't want either of those.
