Microsoft has implemented linking tools in its NTFS operating file systems since Windows NT 4.0 and Windows 2000. These links provide a convenient method for users to access their data.
Over the years Microsoft continued to improve these tools which can now be used to link files and/or directories together. The latest form of file link was introduced in Windows Vista and continues to form part of their latest operating system. In this article we will look at what these file links are and how they differ from one another.
What are NTFS Hard Links, Junctions and Symbolic Links?
Hard links, junction points and symbolic links are linking processes used by Windows to associate other files, directories or volumes. One of the methods to create file links is to use the command line program mklink:
- To create a file hard link: mklink /H linkName target
- To create a directory junction: mklink /J linkName target
- To create a directory symbolic link: mklink /D linkName target
- To create a file symbolic link: mklink linkName target
The following sections describe each type of file link in detail.

One of the best solutions so far is to force everyone on the network to use a dns resolver you control and block the dns request for this domain.
/ip firewall natadd action=dst-nat chain=dstnat dst-address=!<dns-server> dst-port=53 \
protocol=udp to-addresses=<dns-server> to-ports=53
add action=dst-nat chain=dstnat dst-address=!<dns-server> dst-port=53 \
protocol=tcp to-addresses=<dns-server> to-ports=53
Then either create a static dns entry for download.windowsupdate.com pointing to 127.0.0.1 or use the layer7 filter to identify and drop the request.
While I’m always a skeptic when it comes to the government actually doing the right thing, which in this case would be not spending $3.5 trillion on broad entitlements that aren’t needed, I’m not seeing how the two sides get together here. Pelosi is already having a hard enough time rallying the moderates by herself. Now, she has Biden and his White House actively rallying progressives to keep obstructing when they themselves have no leverage to speak of. It’s a recipe for nothing passing at all.
And that’s great if you are a Republican, but it’s still worth noting just how ineffective and impotent Joe Biden is. This is a man who has no sense of his own ability or lack thereof. He truly believes he’s above it all, able to show up at Congress, say “c’mon man” a few times, and have his agenda rubber-stamped. But he’s learning quickly, to the extent he can process what’s even happening, that he has no mandate. I couldn’t think of a better way to start the fall season.
Terry McAuliffe, running for a second, non-consecutive term for the governor of Virginia, let it be known that he thinks parents should have no say in their children’s education, during a recent gubernatorial debate.
According to McAuliffe, “I’m not going to let parents come into schools and actually take books out and make their own decision. … I don’t think parents should be telling schools what they should teach.”
Without missing a beat, McAuliffe’s opponent, Glenn Youngkin, countered with, “You believe school systems should tell children what to do. I believe parents should be in charge of their kids’ education.”
Apparently, McAuliffe, who served as governor of the Commonwealth from 2014 to 2018, is unfamiliar with the law in his own state.
Per the Code of Virginia § 1-240.1. Rights of parents, “A parent has a fundamental right to make decisions concerning the upbringing, education, and care of the parent’s child.”
McAuliffe’s comment, however, is symbolic of the tense divide that is occurring in school districts throughout the nation.
The crux of the matter is simple: Should parents or government bureaucrats determine (for the most part) how and more importantly, what, America’s children learn in public schools.
While it’s not uncommon for Bell Textron to deliver its helicopters to customers around the world, it is unusual for a buyer from Ukraine to pick one up at the factory in Mirabel, Canada, and fly it home. But that’s exactly what an unnamed customer did last week.
After taking delivery of a Bell 407GXi, equipped for IFR flight, the customer rode along with pilot Maksym Lunov, the owner of Ukraine-based Heliclub, one of Bell’s independent representatives in the country. The light single will be used for corporate transportation.
The flight included stops in 13 different countries. “I’ve been a pilot for 13 years,” said Lunov, “and a transatlantic flight is something I’ve always wanted to do. It would not have been easily done without the IFR kit. We had no weather limitations and it allowed us to proceed with the planned route without any delays.” /)

“Battery technology hasn’t changed in over 30 years,” Moshiel Biton, CEO of electric car battery startup Addionics, tells ISRAEL21c.
And here is where Biton saw a huge opportunity “as trillions of dollars will continue to be invested in creating better batteries.” //
Addionics aims to capitalize on this opportunity by introducing a relatively small change into how batteries are designed.
Unlike other companies that focus on improving battery chemistry, Addionics is focused on the physics of a specific part of the battery, the electric current collector.
The current collector serves as the substrate of a battery’s electrodes. These small metal sheets, not dissimilar to aluminum foil, are layered around the “active material” – lithium ion, for example. //
“Using nanotechnology, we can find space that’s not well utilized and make it more efficient,” Biton says.
“That way we get more active material in the same space, which increases the range by keeping the contact between the metal and the active material very high while minimizing internal resistance, enabling higher currents.”
Airlines in most nations are now required to carry out at least a modicum of upset recovery training (UPRT) in flight simulators. Unfortunately simulators are not good at reproducing sustained acceleration forces, so realism is lacking. The European Union Aviation Safety Agency (EASA), aware of both the essential part simulators play in pilot training and of their limitations, is working with simulator manufacturers to upgrade their performance fidelity at the edges of the flight envelope to improve UPRT. The manufacturers have been struggling with EASA deadlines for meeting the performance targets and the effort is ongoing.
What seems to be needed is a way of inculcating in pilots, despite the limitations of UPRT in simulators, an acute awareness that acceleration in flight brings with it the risk of disorientation, and therefore of emphasising the need to ignore all other sensory inputs except the visual picture provided by the flight instruments. This “effective instrument scan” would enable the pilot to control the aircraft attitude and power accordingly. //
Loss of control in flight (LOC-I) has, since the late 1990s, been the biggest killer accident category for airlines. LOC-I linked to somatogravic illusion has frequently occurred, two of the most dramatic recent examples being the March 2016 FlyDubai Boeing 737-800 crash at Rostov-on-Don, Russia, and the August 2000 Gulf Air Airbus A320 crash at Bahrain International airport. Both occurred at night; both involved a go-around. //
there is a general uneasiness with the perception that recurrent training does not attempt to compensate for the insidious effect on pilot cognitive and manual skills of operating with high levels of automation almost all the time.
In the USA the Air Carrier Safety and Pilot Training Aviation Rulemaking Committee recommends that airlines, in their flight manuals, indicate when and where, on revenue flights, manual flying may be carried out by pilots to help maintain their handling skills. In Europe, however, with its denser airspace and stricter rules on where visual flight rules flying may be carried out, manual “flying” practice is basically only available in simulators or base training. //
Until about 20 years ago, the commercially trained and military trained groups had some basic training experiences in common; they both did their early flying in simple aircraft with primitive flight and navigation instruments. Since then, however, the airline sector has grown massively and the military has shrunk, both in relative and in absolute terms. Although there are still military trained pilots in the airlines, their numbers and influence are reducing rapidly.
This change matters, because civil airliners have been designed by their manufacturers according to assumptions about pilot performance that were set in the 1950s and 1960s. In fact, an industry-wide debate about the issue of pilot performance expectations has been reignited recently by the final report on the Lion Air Boeing 737 Max crash near Jakarta, Indonesia.
New NEC requirement and stirring of state/local initiatives seek to address dangers DC power in rooftop PV systems pose to firefighters.
210.8 Ground-Fault Circuit-Interrupter Protection for Personnel. ...(F) Outdoor Outlets. All outdoor outlets for dwellings, other than those covered in 210.8(A)(3), Exception to (3), that are supplied by single-phase branch circuits rated 150V to ground or less, 50A or less, shall have ground-fault circuit-interrupter protection for personnel. This requirement shall become effective January 1, 2023, for heating/ventilating/air-conditioning (HVAC) equipment.
Substantiation: GFCI protection was expanded in the 2020 NEC without HVAC component and equipment safety standards being harmonized with GFCI amperage limits. Currently, the UL standard that HVAC equipment is listed to (UL 1995) has no requirements for leakage current if the unit is hard wired, as most residential air conditioners/heat pumps are. In the future, HVAC equipment will be listed to UL 60335-2-40, which sets a limit of 10 milliamps of leakage current. However, this new standard is not mandatory until 1/1/2024. UL 943 is the standard to which GFCI breakers are listed and are required to trip at 5 milliamps of current. Even if HVAC equipment is listed to the UL 60335-2-40 standard, there is no guarantee it will be compatible with UL listed GFCI breakers This lack of coordination is what is leading to the nuisance tripping that customers are dealing with.
Until both equipment and component standards are updated, designers, installers, AHJs, and consumers are forced to choose between an NEC 2020 compliant installation or an operational installation. In jurisdictions that have adopted 2020 NEC with 210.8(F) intact, there have been numerous instances of field tripping of the GFCI breaker on ductless mini splits, units containing power conversion equipment, and on many single-stage units.

Compare the size of countries, regions and cities
Country size comparison
Using this tool, you can see the relative size of one country compared to another. We'll show you the perimeters of two different countries on the same map. To get started, select two countries below, and hit "Go!".
During his testimony before the House today, CENTCOM head Gen. Frank McKenzie confirmed something that we reported last month – that during a meeting that McKenzie had with the Taliban leader Abdul Ghani Baradar, he was offered the full control of Kabul while evacuation operations were completed.
It was an astonishing report revealed last month – that they had the opportunity to provide a safe withdrawal with the whole city being a buffer around the airport, offered by the Taliban – but turned it down instead opting for the unsafe, completely endangered and at-risk situation they ended up with, at the mercy of the Taliban. It’s likely why U.S. service members and Afghans were killed in the suicide attack. //
Another thing to note was that McKenzie’s meeting with the Taliban came on August 15, the same day the city of Kabul fell. NBC has reported that the day before, McKenzie had warned Baradar that the Taliban shouldn’t come within 20 to 30 kilometers of the city or they would be hit by airstrikes. But then the Taliban took over the city and there were no airstrikes. “The next day, Taliban fighters rolled into Kabul, and no U.S. warplanes bombed the insurgents, the three senior defense officials said,” NBC News said.
Great job there, Biden Administration. They’ll surely take you seriously when you don’t even follow through on a threat like that. But that was essentially the problem with the whole withdrawal – the Biden Administration let the Taliban dictate to them throughout and it cost Americans and Afghan allies their lives.
But the imperatives of climate change and development will inevitably require greater supplies of electricity. It is increasingly clear that nuclear power plants must play a consequential role.
Nuclear power is, in many ways, the most promising source of zero-carbon electricity. Unlike solar, wind and water power, electricity from nuclear plants is predictable; generators run when the sun is not shining, the wind is not blowing and water levels are low. Nevertheless, the industry has a dicey reputation, and there are fewer commercial reactors in operation today in the United States than a generation ago. This year could see three commercial reactors decommissioned in the United States — with plans to shut down about 20 more in coming years.
The problem is a misunderstanding of risks. Humans are constantly exposed to radiation — from the sun, from the cosmos, from the very ground we walk on. Even the most fearsome and publicized nuclear reactor accidents have added relatively little to background levels.
After an earthquake and tsunami wiped out the nuclear plant at Fukushima, Japan, in 2011, scientists concluded that the trauma of a mass evacuation had caused greater health effects than the radiation release. Within months of the 1986 Chernobyl meltdown, in the former Soviet Union, approximately 30 operators and firefighters on-site died of acute radiation syndrome, but investigators nearly two decades later found “no scientific evidence of increases in overall cancer incidence or mortality or in non-malignant disorders that could be related to radiation exposure.” The alarming near-meltdown at Pennsylvania’s Three Mile Island plant in 1979 ultimately exposed neighbors to approximately one-sixth the radiation dose they would receive from having a single X-ray.
Of greater concern are the health risks to uranium miners of extended exposure to natural radiation. Their safety should be protected as the industry advances. But the general fear that has stymied nuclear power over the past generation is unreasonable. //
The model to have in mind is not the hulking plants at Chernobyl or Three Mile Island but the small, imminently reliable reactors that have powered the United States’ submarines and aircraft carriers across more than 134 million miles in 50-plus accident-free years of cruising. Nothing more clearly showcases the potential for safe, reliable nuclear power than these 83 floating demonstration projects, in which healthy sailors live in proximity to tireless fission power plants.
Carbon emissions and other greenhouse gases are the environmental challenge of our age. Nuclear power is one tool for ridding ourselves of them — while keeping the lights on.
