Another approach is to use Git. No, seriously, I know it's like a programmer thing, but it works for all text files and can technically work for xml based files like Word also.
If you're not confident on using a command prompt, check out Github Desktop. Contrary to the name you don't have to put repositories it makes online (and if you do they don't have to be public).
Git is helpful because all those versions of files don't remain visible in one folder, you always just see the most recent version. Past versions exist in the commit history, and you can. Roll back to specific versions, branch off from them, all that good stuff.
REMEMBER: WHEN YOU'RE WORKING ON A PIECE OF WRITING, NEVER DELETE ANYTHING
Ok, so you have a big paper due in July. You make a folder for the project called "Big Paper." You get to work, and save a file titled "PaperTopic.doc" in that folder.
You go back to your draft the next day. DO NOT simply open "PaperTopic.doc" and start editing/adding/revising. You are going to make a folder titled "Paper Versions." You are going to make a copy of "PaperTopic.doc." You are going to move it into the "Paper Versions" Folder.
Then you are going to go back to the original "PaperTopic.doc," and rename it "PaperTopic 5.14.24.doc." And you're going to repeat this EVERY DAY that you work on this project. Soon the "Paper Versions" will look like this:
Tumblr media
I post about this every 6 months or so, and I will continue to do so; because one day, it WILL save your ass. You're welcome.
Also, back it up to an external hard drive at least once a week.

Building Nuclear Power Plants in Hurricane Alley: Think Again?
All text copyrighted ©️ 2025 by Lancer Gareth Bailey
Dow Industries recently unveiled plans to construct four nuclear power plants along the Texas Gulf Coast—an area famously nicknamed “Hurricane Alley.” While the company promises clean, reliable energy, the proposal raises critical safety concerns that can’t be ignored.
Texas’ coastline is no stranger to nature’s fury. This region faces a trifecta of extreme weather threats: hurricanes, flooding, and increasingly unpredictable power grid behavior. In recent years, we’ve seen firsthand how these forces can cripple infrastructure. Now, imagine those same forces converging on a nuclear facility.
When hurricanes make landfall, they bring not just high winds, but massive storm surges and torrential rains. These can knock out power, flood backup generators, destroy infrastructure, and limit access for emergency crews. Add to that the Texas heat, which can stress cooling systems, and winter storms like the 2021 blackout event that left much of the state in the dark for days. Every one of these hazards could pose serious challenges to a nuclear plant’s ability to maintain safe operations—not just during normal use, but especially during shutdown and emergency conditions.
The risks aren’t hypothetical.
During Hurricane Sandy in 2012, the Oyster Creek Nuclear Generating Station in New Jersey—though already offline—issued an emergency alert as floodwaters rose dangerously close to disabling its spent fuel pool cooling systems. Just a few more feet, and it might’ve mirrored the disaster that unfolded in Japan the year before.
Fukushima Daiichi, one of the most technologically advanced nuclear plants in the world, was also shut down ahead of the 2011 tsunami. That didn’t stop catastrophe. Flooding knocked out the backup generators that powered its cooling systems, leading to a partial meltdown, hydrogen explosions, and widespread radioactive contamination. The world learned that even a powered-down plant can become a disaster zone if cooling is lost.
Which brings us to a common misconception: Can’t we just shut down a plant before a storm hits? Yes—and operators often do. But turning off the reactor doesn’t mean the danger ends. Even in shutdown, nuclear fuel continues to generate heat for days or weeks. That heat must be actively managed and cooled—usually with pumps that require power. If floodwaters knock out the electrical systems or disable generators, it could lead to a cascade of failures. The same applies to spent fuel pools, which house older but still highly radioactive fuel rods. If those pools overheat, they can boil off coolant water, ignite fuel rods, and release radiation.
So while Dow Industries may tout their plan as safe and forward-thinking, the public deserves more than assurances. We need absolute clarity on how these facilities will be hardened against storm surges, flooding, wind damage, prolonged grid outages, and cooling system failures. We need to know whether emergency responders can access these sites during a hurricane. And we need to ask why—after all we’ve learned—any company would choose to build nuclear reactors in one of the most weather-vulnerable regions in the country.
Clean energy is critical. But it cannot come at the cost of basic common sense. If we ignore the lessons of the past, we may end up repeating them—with consequences too great to bear.
⸝
Counterarguments:
1. Proximity to Industrial Demand
The Texas Gulf Coast is home to some of the largest petrochemical and manufacturing complexes in the world, including Dow’s own operations in Freeport and along the coast. These facilities require massive, stable, around-the-clock electricity, far beyond what wind or solar can reliably deliver on their own.
• Nuclear energy offers baseload power—it runs continuously and isn’t subject to the intermittency of renewables.
• Locating nuclear plants close to demand centers reduces transmission losses and costs, and increases grid stability.
2. Nuclear is a Clean Energy Source
In an era of accelerating climate change, even traditionally carbon-heavy industries are under pressure to decarbonize.
• Nuclear power produces zero carbon emissions at the point of generation, making it a crucial tool in the fight against climate change.
• Texas already leads in wind and solar, but pairing those with reliable nuclear could help phase out coal and natural gas faster.
3. Advanced Reactor Designs Are Safer
Since the Fukushima disaster, U.S. plants have undergone significant upgrades, including the implementation of FLEX strategies, redundant safety systems, and passive self-shutdown capabilities that don’t rely on electric pumps or operator intervention to stay safe in emergencies. Newer reactors, especially the small modular reactors (SMRs) being proposed by Dow, are designed to be even more resilient.
• These designs can automatically cool themselves, even if power is lost.
• New containment structures are engineered to withstand flooding, high winds, and seismic events.
4. Economic Development
The project would likely bring thousands of high-paying construction and engineering jobs, as well as long-term skilled employment for plant operators, security, and maintenance crews.
• It could transform coastal communities economically, providing tax revenue and infrastructure investment.
• It may also attract other industries looking for stable, low-carbon energy sources.
5. Texas is No Stranger to Big Infrastructure
Supporters might argue that if any state has the resources, space, and technical capability to build resilient nuclear facilities in a challenging environment, it’s Texas. They may point to the state’s experience with large-scale oil & gas infrastructure and its growing leadership in energy innovation.
Additionally, there is already precedent for safe nuclear energy along the Texas coast.
The South Texas Project (STP), located near Bay City, has operated two nuclear reactors since the 1980s without a single severe accident, radiation leak, or environmental contamination. Even when tested by nearby Category 4 Hurricane Harvey in 2017, the plant remained stable and fully operational. While there have been a few minor incidents—like a transformer failure and a switchyard fire in 2024—none compromised safety systems or public health.
⸝
But… Asterisks Everywhere
Each of these arguments comes with caveats:
• Modern reactor designs are promising, but not yet widely deployed or tested under real-world hurricane stress. No current reactors have been tested against a direct hit by a category 4 or 5 hurricane. Hurricanes are getting stronger due to climate change. A direct hit from a Category 4 or 5 storm—even if not catastrophic—could still force expensive shutdowns, damage infrastructure, and disrupt energy delivery.
• Clean energy goals are crucial—but placing critical infrastructure in high-risk zones may undermine those goals in the long term.
• Economic development is good—but who bears the risk if something goes wrong? Likely the surrounding communities.
⸝
Side Note: Is Nuclear Power Truly “Clean” Energy?
While nuclear power generation itself emits no carbon dioxide, labeling it as “clean” overlooks the significant challenge of radioactive waste management. High-level radioactive waste, such as spent nuclear fuel, remains hazardous for thousands to hundreds of thousands of years, depending on its isotopic composition. For instance, plutonium-239 has a half-life of about 24,000 years, meaning it takes that long for half of its radioactivity to decay. Managing such long-lived waste necessitates secure containment strategies to prevent environmental contamination and protect human health over extensive periods.
Currently, most high-level waste is stored on-site at nuclear facilities, awaiting the development of permanent disposal solutions like deep geological repositories. The long-term stewardship required for this waste poses ethical and logistical challenges, as it demands reliable containment and monitoring systems that can function effectively for millennia.
Therefore, while nuclear energy contributes to reducing greenhouse gas emissions, its classification as “clean” must be weighed against the enduring responsibility of managing its radioactive byproducts.

A mountain in New Zealand considered an ancestor by Indigenous people was recognized as a legal person on Thursday [January 30, 2025] after a new law granted it all the rights and responsibilities of a human being.
Mount Taranaki — now known as Taranaki Maunga, its Māori name — is the latest natural feature to be granted personhood in New Zealand, which has ruled that a river and a stretch of sacred land are people before. The pristine, snow-capped dormant volcano is the second highest on New Zealand's North Island at 2,518 meters (8,261 feet) and a popular spot for tourism, hiking and snow sports.
The legal recognition acknowledges the mountain's theft from the Māori of the Taranaki region after New Zealand was colonized. It fulfills an agreement of redress from the country's government to Indigenous people for harms perpetrated against the land since.
How can a mountain be a person?
The law passed Thursday gives Taranaki Maunga all the rights, powers, duties, responsibilities and liabilities of a person. Its legal personality has a name: Te Kāhui Tupua, which the law views as "a living and indivisible whole." It includes Taranaki and its surrounding peaks and land, "incorporating all their physical and metaphysical elements."
A newly created entity will be "the face and voice" of the mountain, the law says, with four members from local Māori iwi, or tribes, and four members appointed by the country's Conservation Minister.
Tumblr media
Why is this mountain special?
"The mountain has long been an honored ancestor, a source of physical, cultural and spiritual sustenance and a final resting place," Paul Goldsmith, the lawmaker responsible for the settlements between the government and Māori tribes, told Parliament in a speech on Thursday.
But colonizers of New Zealand in the 18th and 19th centuries took first the name of Taranaki and then the mountain itself. In 1770, the British explorer Captain James Cook spotted the peak from his ship and named it Mount Egmont.
In 1840, Māori tribes and representatives of the British crown signed the Treaty of Waitangi — New Zealand's founding document — in which the Crown promised Māori would retain rights to their land and resources. But the Māori and English versions of the treaty differed — and Crown breaches of both began immediately.
In 1865, a vast swathe of Taranaki land, including the mountain, was confiscated to punish Māori for rebeling against the Crown. Over the next century hunting and sports groups had a say in the mountain's management — but Māori did not.
"Traditional Māori practices associated with the mountain were banned while tourism was promoted," Goldsmith said. But a Māori protest movement of the 1970s and '80s has led to a surge of recognition for the Māori language, culture and rights in New Zealand law.
Redress has included billions of dollars in Treaty of Waitangi settlements — such as the agreement with the eight tribes of Taranaki, signed in 2023.
How will the mountain use its rights?
"Today, Taranaki, our maunga, our maunga tupuna, is released from the shackles, the shackles of injustice, of ignorance, of hate," said Debbie Ngarewa-Packer, a co-leader of the political party Te Pāti Māori and a descendant of the Taranaki tribes, using a phrase that means ancestral mountain.
"We grew up knowing there was nothing anyone could do to make us any less connected," she added.
The mountain's legal rights are intended to uphold its health and wellbeing. They will be employed to stop forced sales, restore its traditional uses and allow conservation work to protect the native wildlife that flourishes there. Public access will remain.
Do other parts of New Zealand have personhood?
New Zealand was the first country in the world to recognize natural features as people when a law passed in 2014 granted personhood to Te Urewera, a vast native forest on the North Island. Government ownership ceased and the tribe TĹŤhoe became its guardian.
"Te Urewera is ancient and enduring, a fortress of nature, alive with history; its scenery is abundant with mystery, adventure, and remote beauty," the law begins, before describing its spiritual significance to Māori. In 2017, New Zealand recognized the Whanganui River as human, as part of a settlement with its local iwi.
How much support did the law receive?
The bill recognizing the mountain's personhood was affirmed unanimously by Parliament's 123 lawmakers. The vote was greeted by a ringing waiata — a Māori song — from the public gallery, packed with dozens who had traveled to the capital, Wellington, from Taranaki.
The unity provided brief respite in a tense period for race relations in New Zealand. In November, tens of thousands of people marched to Parliament to protest a law that would reshape the Treaty of Waitangi by setting rigid legal definitions for each clause. Detractors say the law — which is not expected to pass — would strip Māori of legal rights and dramatically reverse progress from the past five decades.
-via NPR, January 31, 2025
--
Note: The article doesn't get fully into the implications of the broader, global "rights of nature" movement (of which this is part), which is powerful tool for not only recognizing Indigenous ways of relating to the world, but also preventing ecological damage.
Examples of rights of nature include rivers having the right to not be polluted, etc. Powerful tool for leveraging the courts and legal frameworks against environmental destruction.

Does A Surge Protector or a UPS Protect Against Lightning?
When people mention surge protector, in most cases they think of a device that is plugged into the wall power socket and used to protect one or more sensitive devices from power surges.
Such point-of-use surge protectors feature an electronic sensor that detects the power surges and an additional component that redirects the excess electric energy to the ground wire - hence the energy (given in Joules (J)) that the surge protector can redirect successfully is often one of the more important features of any surge protector.
Since the damage from power surges accumulates over time, it is recommended to replace surge protectors every few years.
Uninterruptible Power Supply (UPS) is basically a point-of-use surge protector that also comes with a built-in battery which is used to power connected devices when there is no AC power present.
