A CNC router machine is probably the most useful tool a hobbyist can own, but the price for a CNC machine on the market is way more than the average hobbyist is willing to spend. You can build your own CNC with very basic tools, little knowledge of machinery, mechanics, or electronics, but be warned, these machines are inherently dangerous, so wear the proper protection and use common sense. At the very least, read the instructions and precautions on every tool you use.
Hand planes are the epitome of fine woodworking. Extreme woodworkers use them, and serious collectors collect them.

Planes can range in price from about $25 for new, economical models to planes that cost several hundred dollar...

This is a Google Tech Talk from March, 26 2008. Timothee Cour - Research Scientist lectures. Movies and TV are a rich source of highly diverse and complex video of people, objects, actions and locales "in the wild". Harvesting automatically labeled sequences of actions from video would enable creation of large-scale and highly-varied datasets. To enable such collection, we focus on the task of recovering scene structure in movies and TV series for object/person tracking and action retrieval. ...

Post-exploitation is often not quite as exciting as popping the initial shell, but it's a crucial phase for gathering data and further privilege escalation. Once a target is compromised, there's a lot of information to find and sift through. Luckily, there are tools available that can make the process easy. One such tool is Postenum.
Password cracking is a specialty of some hackers, and it's often thought that raw computing power trumps everything else. That is true in some cases, but sometimes it's more about the wordlist. Making a custom, targeted wordlist can cut down cracking time considerably, and Wordlister can help with that.
It is often said that the best hackers remain unknown, and the greatest attacks are left undiscovered, but it's hard for an up-and-coming penetration tester or white hat to learn anything unless one of those factors is actually known or discovered. But the end goal here in our SQL injection lessons is to make that statement as true as possible for us when performing our hacks.
On June 11, 2016, an Arizona woman died from what appeared to be several infections, including pneumonia. She likely caught at least one of these from her dog.
Add breathing in your house as another possible danger to your health. If your home is sick, it's possible you could get sick too.
Most of us have already had an encounter with the Epstein-Barr virus, or EBV, for short. As part of the herpes family, it's one of the most common disease-causing viruses in humans. We get the disease with (or without) some nasty symptoms, then we recover. However, EBV stays in our body after the illness has ended, and it's one of the few viruses known to cause cancer.
Dengue fever is a danger to anyone living or visiting tropical or subtropical regions. It can be hard to detect the infection in its earliest and most treatable phase, especially in children. Luckily, new research highlights better techniques for triaging the disease in infected children with more severe symptoms, potentially saving lives.
The problem with HIV is that it attacks and kills the very cells of the immune system that are supposed to protect us from infections — white blood cells. But a new technique, developed by scientists at The Scripps Research Institute (TSRI) in La Jolla, California, offers a distinct HIV-killing advantage.
As summer mosquito season approaches, researchers are warning people with previous exposure to West Nile virus to take extra precautions against Zika. A new study found that animals with antibodies to West Nile in their blood have more dangerous infections with Zika than they would normally.
In the ongoing search to find better ways to use antibiotics, an extract made from maple syrup has some surprisingly important medical benefits.
Viral infections have been the focus of attention in the development of autoimmune diseases—diseases where the body's immune system reacts to the body's own cells—because they trigger the immune system into action.
The culprit probably wasn't what doctors were expecting when a 57-year-old man in Hong Kong came to the hospital. The patient was admitted to the intensive care unit in critical condition. A clue to the cause of the infection would lie in the man's profession—he was a butcher.
Even as health authorities describe the symptoms of Zika infection in the general population as mild, a new surveillance study finds serious side effects are more common, and serious, than previously thought.
Despite the availability of a vaccine against it, almost 50% of men aged 18-59 in the US are infected with the human papillomavirus (HPV). Why?
To much of the United States, Zika seems like a tropical disease that causes horrible problems in other countries but is nothing to be worried about stateside. It may make you rethink your beach vacation abroad, but not much more than that. However, if you live in Florida or Texas, the possibility of getting a Zika infection where you live is real — and local outbreaks are more and more a possibility.
Creamer, milk (whole or skim), sugar, or even butter—you've probably added at least one of these to your coffee to improve its taste at some point.

Common knowledge is a funny thing: it represents a majority's opinion on a particular subject and somehow makes that opinion fact. If that 'fact' goes unopposed and unchallenged, then it is passed on and preserved from one generation to the next—regardless of whether it is true or not.

Similar to pop-up books, these instructional tools mimic the act of human dissection, allowing doctors and students to study the intricacies of the body normally concealed by flesh.
