When it's time for me to get ready for bed, I find a quiet place for a quick "oil check," as I like to call it. I do some deep breathing to start, just to calm my heartbeat (inhale four seconds, exhale four seconds). Then, I note three things I accomplished that day and how they positively impacted others. Close with more breathing, then I get ready for bed.

You've probably heard this before, but it's true -- cut the screen time if you want to clear your head and have a good night's rest. So, I put my phone on its charger, climb into bed, and lie on my back. Before tucking in, I note three things I'd like to accomplish the next day -- not pie-in-the-sky ambitions, but things I can reasonably do in the next 24 hours.

Lastly, I call on a happy memory, typically of something I did I was very proud of. It's not always recent, either -- I remember smiling to myself over a standing ovation at a high school play. With this image in my head, I close my eyes and gradually fall asleep.

You can compact using GUI tools, but PowerShell provides the complete method. Remember two things:

• You cannot compact a VHDX connected to a running virtual machine.
• The computer system that runs the Optimize-VHD cmdlet must have the complete Hyper-V role installed. The PowerShell module alone does not contain the necessary system services. If you must run the compact operation on a system that does not have Hyper-V, you can use diskpart instead.

The process centers around the Optimize-VHD cmdlet. In general, you’ll want to mount the VHDX into the management operating system to get the best results. For example:

Mount-VHD .dyndisk.vhdx -ReadOnly
Optimize-VHD .dyndisk.vhdx -Mode Full
Dismount-VHD .dyndisk.vhdx

Be aware that even for very small files, that can take some time to complete. The amount of time depends mostly on your available CPU cycle and the speed of your disk subsystem.

VAN HORN, Texas, Oct 13 (Reuters) - Having made a career out of playing an explorer of the cosmos, William Shatner - Captain James Kirk of "Star Trek" fame - did it for real on Wednesday, becoming at age 90 the oldest person in space aboard a rocketship flown by billionaire Jeff Bezos's company Blue Origin, an experience the actor called profound.

Lots of people confuse “shrink” with “compact” for virtual hard disks. The “compact” operation squeezes the empty bits out of a dynamically expanding hard disk to reduce the amount of space that it consumes on physical disk. Compacting does not alter the maximum size of the disk, nor does it report anything different to the guest operating system. Furthermore, “compact” does not work on fixed VHDX at all. The “shrink” operation, the topic of this article, reduces the physical consumption of a VHDX and reduces the disk size reported to the guest OS. //

What to remember: A compact operation reclaims the space from empty blocks. A shrink operation reclaims the space from unallocated blocks. We will make the distinction more obvious when we look at the shrink operation. //

You Cannot Shrink a VHDX that Contains a Dynamic Logical Disk

If the logical disk inside the VHDX that you’re working with is Dynamic, then you can’t shrink it. Do not confuse the Dynamic logical disk with dynamically expanding VHDX, as they are dramatically different things. //

The moral of the story: don’t use Dynamic logical disks. Hyper-V isn’t the only thing that doesn’t know what to do with them. Unfortunately, some products out there require Dynamic disks. Even at Microsoft, at least one team hasn’t yet gotten the memo to stop using Dynamic disks. So, the secondary moral: if you must use Dynamic logical disks, provision small because you can always grow them.

This article is presented to you as a tool for performing virtual-to-physical conversions because it is universally applicable to any target hardware environment. However, because it is target-neutral, the steps presented here could very easily be adapted to other situations. For instance:

• Virtual-to-virtual conversions for which there is no applicable tool
• Physical-to-virtual conversions
• VHDX-to-physical conversions //

Virtual-to-Physical Conversions are Not Ideal

My first recommendation is: find another way. Even though V2P is possible, it has a fairly high chance of being unsuccessful even with your best effort. A preferred approach would be migration. Install the desired operating system on the new hardware and migrate settings and applications. Most software vendors have a documented method for performing this. You are almost guaranteed to prefer the process and results over a V2P.

If you’re using Hyper-V Server and you’re converting a VM running a recent version of Windows, you could install the OS on the physical hardware and then mount the VHDXs directly inside the new operating system and transfer files via copy, xcopy, robocopy, Windows Explorer, etc.. //

The very first thing you must do is take a complete backup of the machine to be converted. You are going to absolutely rework this machine from bottom to top, things are almost definitely going to go wrong, and your sole saving grace will be a good backup. //

Your virtual machine should be off before proceeding. You’ve got a clean virtual machine, but what you need is a clean image. The easiest way to proceed from here will be to use some form of imaging software. There is any number of solutions available, but these directions will use Clonezilla Live. If you have some other product, the process should be similar.

There are two basic methods to perform a clone. One is over the network, the other is is by hard drive transfer. I’ll show you the basic setup operations for each method, and then in the next section, I’ll go through running Clonezilla with appropriate branches to fit your method.

Meet Nate Laps, a former gas industry land agent who switched sides and now fights for landowners. He may well change how FERC and pipeline builders treat the people who live in the path of major energy projects.

Laps, 38, is brawling with two multibillion-dollar natural gas companies — Cheniere Energy Inc. and Spire Inc. — along with FERC itself.

Laps has bird-dogged Cheniere’s Midship pipeline through Oklahoma and Spire’s STL pipeline near St. Louis for years on behalf of his landowner clients. It’s no coincidence that both projects are in trouble with FERC for their treatment of landowners.

To properly sizing the amount of capacitor (kVAR) required to correct the lagging power factor,we must have three (3) important of information below:

• kW (kilowatts)

• Existing Power Factor ( % )

• Desired Power Factor ( % )

From this information,now we can calculate the capacitor size for power factor correction.The formula to calculate the required kVAR is:

Calculation Example :

1 unit air-compressor ( 3 phase 415 VAC ) used an average of 90 kW with an existing power factor of 80%.The desired power factor is 95%. The factor value for this case is 0.421 to raise the power factor from 80% to 95% using table 1.

0.421 x 90 kW = 38 kVAR

In order to calculate power factor correction for your installation, your should follow the steps below: //

At the end of the spreadsheet you will get the calculation of the energy savings for above power factor correction.

Why in the world was the passenger in custody for “several hours”? They didn’t do anything wrong.

In short the reason is due to,

1, Uncertainty.
2, Political wallpapering. //

So “uncertainty” will always be there even if the probavility is very small.

Which is where we move from demonstrating “uncertainty” to demonstrating “political wallpapering”.

From a political perspective if it became known after a bomb went off that some one had alerted the authorities and the authorities failed to investigate then it would at the very least be a total PR disaster[2] for the politicians.

So to avoid such “PR disasters” happening for “Politicians” they have authorities under their nominal control issue avoidence rules that effectively say,

“Until proven otherwise all notified threats are to be treated as credible and must be acted upon.”

So if person B says the object person A has in their possession is a security threat the “Untill proven otherwise…” rule kicks in untill the uncertainty is resolved.

However this rule is not just in relation to aircraft security… //

Thus a “Political Rule” has become a weapon in it’s own right. That can be used against individuals and organisations via “denial of XXX” be it “Service”, “Rights”, “Liberty”, “Reputation”, etc, etc.

As we saw with the “bomb in a printer” scare, some years back, the bomb does not have to be viable in any way what so ever to cause very substantial damage.

The thing is it is a “no win” issue no matter what you do. 9/11 two decades back happened because those who committed the acts, had previously tested and found they could get box-cutters onto aircraft in their pockets or “carry on”.

Any expert will tell you “any object can be seen as a weapon” all that has to be done is “Work out how to realise the transformation”.

To recursively set prop for pool/fs/root and descendants with the exception of a few (eg mountpoint) non-inherited props:
zfs set prop=val pool/fs/root

Recursively reset (restore prop to inherited (if set "higher" in the tree) or default otherwise, or remove (if a user prop)):
zfs inherit -r prop pool/fs/root
//

You can delete a user property (those with a colon, e.g. com.sun:auto-snapshot:yearly) with the zfs inherit command, e.g
zfs inherit com.sun:auto-snapshot:yearly <dataset>

From RTFM zfs(8): Use the "zfs inherit" command to clear a user property. If the property is not defined in any parent dataset, it is removed entirely. Property values are limited to 1024 characters. //

Inheriting nonexistance, thats fun. I think a parent should be able to force behavior on its lineage, as well as trusting the child to imitate its behavior. Maybe the developers are training us to be better parents.

A simple cooling system driven by the capture of passive solar energy could provide low-cost food refrigeration and living space cooling for impoverished communities with no access to the electricity grid. The system, which has no electrical components, exploits the powerful cooling effect that occurs when certain salts are dissolved in water. After each cooling cycle, the system uses solar energy to evaporate the water and regenerate the salt, ready for reuse. //

After comparing a range of salts, ammonium nitrate (NH4NO3) proved to be the standout performer, with a cooling power more than four times greater than its closest competitor, ammonium chloride (NH4Cl). The ammonium nitrate salt’s exceptional cooling power can be attributed to its high solubility. “NH4NO3’s solubility reached 208 grams per 100 grams of water, whereas the other salts were generally below 100 grams,” Wenbin says. “This salt’s other advantage is that it is very cheap and already widely used as fertilizer,” he adds.

The system has good potential for food storage applications, the team showed. When the salt was gradually dissolved in water in a metal cup placed inside a polystyrene foam box, the temperature of the cup fell from room temperature to around 3.6 degrees Celsius and remained below 15 degrees Celsius for over 15 hours. //

With the ongoing retirement of the Boeing 747-400 and the end of production of the Airbus A380, there is no doubt four-engine aircraft are falling out of favor. Twin-engine aircraft have improved significantly, and many airlines are moving away from the high-capacity ‘hub and spoke’ model. It seems unlikely there will be a need anytime soon for a four-engine passenger aircraft, but perhaps it could re-appear for freight. //

Four engine production has declined as twin-engine operations have improved. In the early days of jet aircraft, a twin-engine aircraft (under FAA rules) could not fly more than 60 minutes away from a diversion airport. This hugely limited the possibilities for trans-oceanic flights. //

Along with this improvement in ETOPS, engine power has also increased. A 1958 Pratt & Whitney JT3D engine on the 707, for example, had a thrust of 17,000 pounds, versus the GE9X engine on the 777X with around 105,000 pounds of thrust. Manufacturers can now power large single-deck widebodies with two engines.

SB Energy Corp., a U.S. renewable-energy firm that’s an arm of Japan’s SoftBank Group, is making a record purchase of the batteries manufactured by Energy Storage Systems. The Oregon company says it has new technology that can store renewable energy for longer and help overcome some of the reliability problems that have caused blackouts in California and record-high energy prices in Europe.

The units, which rely on something called “iron-flow chemistry,” will be used in utility-scale solar projects dotted across the U.S., allowing those power plants to provide electricity for hours after the sun sets. //

The battery is made of iron salt and water,” said Hossfeld. “Unlike lithium-ion batteries, iron flow batteries are really cheap to manufacture.”

Every battery has four components: two electrodes between which charged particles shuffle as the battery is charged and discharged, electrolyte that allows the particles to flow smoothly and a separator that prevents the two electrodes from forming a short circuit.

Flow batteries, however, look nothing like the battery inside smartphones or electric cars. That’s because the electrolyte needs to be physically moved using pumps as the battery charges or discharges. That makes these batteries large, with ESS’s main product sold inside a shipping container.

What they take up in space, they can make up in cost. Lithium-ion batteries for grid-scale storage can cost as much as $350 per kilowatt-hour. But ESS says its battery could cost $200 per kWh or less by 2025.

An Austrian-based company is working on a patented propulsion technology for VTOLs (vertical take-off and landing) and has recently shared the first test flight of a prototype aircraft using the unique approach. //

In the footage released by CycloTech, the prototype is tethered and tested indoors. Finally, the aircraft is able to successfully take off, hover in the air, and land. While it is not the same as actually testing the technology outside, it is nevertheless a good start in wind conditions.

CycloTech claims its rotor technology brings several advantages. Precision is one notable benefit of the CycloRotor. Being able to steer the magnitude and direction of thrust 360 degrees around the rotation axis of every single rotor offers better maneuverability of the aircraft.

National leaders around the world are announcing big plans to return to nuclear energy now that the cost of natural gas, coal, and petroleum are spiking, and weather-dependent renewables are failing to deliver.

“The number one objective is to have innovative small-scale nuclear reactors in France by 2030 along with better waste management,” said French President Emmanuel Macron.

Macron had previously promised to reduce nuclear from 75 to 50 percent of its power, noted Financial Times. “But the mood has now changed,” the paper writes today. “Macron said on Tuesday he would begin investing in new nuclear projects ‘very quickly.’”

the Congressional Budget Office (CBO) published a paper demonstrating what would happen if a sustained increase in federal spending were coupled with big tax increases to pay for the spending.

While the analysis points to different long-term effects from different types of taxes, any tax-and-spend approach would lead to reductions in economic growth and personal income that are larger than the size of the tax hikes.

For example, the analysis found that having 10% more federal government would mean a 12% to 19% reduction in personal consumption.

And that’s a conservative estimate. Most estimates show tax hikes shrink the economy by two to three times more than the revenues they raise. //

While the Biden administration has repeatedly claimed that it will only seek to raise taxes on the wealthy, a government of the size that they’re seeking would require amounts of money that can only be generated through steep across-the-board tax increases on middle-class Americans.

Regardless of whether those taxes are levied tomorrow or in a few years, they would be an inevitable part of expanding the size and scope of the federal government.

Rather than continuing down the path of centralized power and socialism, lawmakers should recognize the costs associated with endless federal spending and chart a course towards financial responsibility and prosperity.

I once watched two engineers/technicians argue for two hours about what power definitions should be displayed on a HMI interface. One of them argued that VARs were being EXPORTED during lagging conditions, so a lagging current should be shown as POSITIVE VARS and Power Factor! The other argued that VARs were IMPORTED during lagging conditions, so a lagging current should be shown as NEGATIVE VARs and Power Factor!

I was fairly new to the business and had no skin in the game, so I couldn’t contribute at the time, but I did find both arguments compelling and the whole scene was hilarious. Now that I’ve had some experience, I realize that they were both correct… from their perspectives.

Here’s an excerpt from The Relay Testing Handbook: Generator Relay Protection Testing that should help clarify how Phasor Diagrams can be interpreted differently by electrical workers with different backgrounds, and why you should NEVER plot a phasor on a Power (P-Q) Diagram:
