Keylogging & trojans - A keylogger can keep a log of your keystrokes, including usernames and passwords.This attack often succeeds against weak and predictable passwords. Dictionary attack - Programs run through a prearranged list of common passwords to find a hit for the targeted user.Brute force attack - Automated programs that can generate every possible password combination until a match is found, perfect for cracking passwords that are 8 characters or fewer.Data breach - Hackers break into a company’s servers and publish private information (including user login details) to the public.Phishing attacks - Scam websites, texts, or emails that imitate legitimate entities to steal login data and financial information.There are various password hacking techniques cyber criminals use, such as: Strong passwords can withstand most password crackers, and using a unique password for each account ensures that not all of your accounts will be compromised if one password gets stolen. Phishing attacks are also a major threat - millions of users give away their login information to scam websites every year, with phishing attacks growing hugely over text message and social media in the last few years. Hackers use these to try to access random accounts. Password cracking tools can hack basic passwords like “qwerty” and “12345” in a few minutes, and there are huge databases of passwords that have been leaked in data breaches. TRY THE BEST PASSWORD MANAGER IN 2023 (1PASSWORD) Why It’s Important to Create Strong and Unique Passwords I also recommend the best password managers of 2023 (hint: 1Password is #1). This article explains the basics of password security, how to create strong passwords, and how to discover if your passwords have been compromised. Password managers use security tools like random password generators and secure 2FA options to keep your logins secure, even in the face of a data breach. That’s why it’s important to use a password manager. For example, LinkedIn was breached in early 2021, giving hackers access to over 700 million users’ login information. It’s great to generate secure passwords for every site you use, but even if you do, you could still have your password leaked in a data breach. ![]() If you’re using the same password for all of your accounts, all it takes is one successful hack, and all of your accounts can be broken into simultaneously. A good password should have at least 16 random characters, or you can use a passphrase with at least 4 words and 15–20 characters - but the most important thing is that it should be unique. It’s easy to create a strong password in 2023, especially if you use a secure password manager. ![]() Generate a password with at least 16 characters and store it in your password manager’s secure vault. From your password manager’s main screen, navigate to the password generator tool. Install the password manager (this only takes a few minutes), and then proceed to step 2.

These measurements apply for use with a 370-grain Pro Light Carbon Arrow. TenPoint refers to its mechanism as the “ACUslide,” and it too allows for easy cocking & un-cocking.Īs for power, the Vapor RS470 is the most powerful crossbow in our guide, with a 470 fps max speed and 180 ft-lbs of kinetic energy. Next, the cocking system is similar to Ravin’s, as it’s both silent and built into the bow. During your hunts, you cut out all guesswork with the Xero, leading to dangerously accurate shots.Īdditionally, the Xero automatically adjusts to changing light conditions to ensure the illuminated aim points can always be seen clearly. If you’re unfamiliar with the Xero scope, it’s the finest digital rangefinding scope on the market. First off, this crossbow goes well beyond just sporting a built-in cocking device. If you weren’t satisfied with the scope on the Ravin R29X or just want a top-of-the-line crossbow, the RS470 is worth a long look. Plus, there’s never a question as to whether a Ravin crossbow will be accurate when it comes time to take your shot. All in all, hunting from a climbing treestand or blind is the ideal use for the R29X because of its mix of power and its compact size. When cocked, the R29X measures a compact 6″ axle-to-axle.Īdditional highlights of the HeliCoil system are frictionless floating arrows, perfectly level cams & string, and the included accessory package w/ scope. Regarding power, the R29X sports an impressive 450 fps max velocity & 180 ft-lbs of kinetic energy while managing to weigh just 6.75 lbs. Second, the R29 series is the first to feature Ravin’s Silent Cocking System for super stealth operation in the field. Plus, it allows you to quickly and safely cock/un-cock your bow. With this ambidextrous system, the bow requires just a 12lb minimum cocking weight. First, the main component that makes the R29X our top pick is the Versa-Draw Cocking System. This, my friend, is absolutely one of the best crossbows on the market with the premium advanced HeliCoil tech. #1) Ravin R29X w/ HeliCoil Technology & Silent Cocking System ![]() In each of our reviews, we deliver all the most important points to consider on your journey to choosing the perfect crossbow.

This project proposal, incorporating $6.8 million of Bipartisan Infrastructure Law funding received to date, is now available for public comment at the Tahoe National Forest website.WWF and partners are on the forefront of implementing and delivering forest landscape restoration (FLR) at the scale that is needed to deliver global commitments. The project is proposed to be completed in stages, providing the community opportunity to voice feedback as landscape conditions may evolve. Restoration efforts are expected to take many years, with the most critical project areas targeted first. Phase one of the project would treat 32,000 acres of forest surrounding Downieville, California to reduce the threat of catastrophic wildfire and to begin to restore the watershed to a healthier, more resilient state. ![]() The North Yuba Landscape Resilience Project proposes a treatment plan for the 275,000 acres of federal land within the watershed. North Yuba Landscape Resilience Project Proposal However, more work is needed to further protect communities from wildfire risk and improve forest health on a landscape scale. This work reduced hazardous fuels and protected watershed health within the North Yuba landscape, encouraging ecological resilience. Previously completed forest restoration on the North Yuba landscape includes over 1,000 acres of prescribed fire treatment, 3,000 acres of mechanical thinning, 400 acres of Aspen restoration, over 300 acres of meadow restoration, and 30 acres of hazard tree removal in recreational and camping areas. The member organizations of the North Yuba Forest Partnership include Sierra County, National Forest Foundation, The Nature Conservancy, Yuba Water Agency, Blue Forest Conservation, Camptonville Community Partnership, the Nevada City Rancheria of the Nisenan, South Yuba River Citizens League, and the Tahoe National Forest.Ĭompleted Work in the North Yuba Landscape The partnership aims to improve forest health on the Tahoe National Forest and reduce wildfire risk to adjacent communities nestled within the 275,000-acre footprint of the North Yuba landscape, which stretches from New Bullards Bar Reservoir east up to the Sierra Crest along Highway 49. “Everyone is contributing, including substantial funding from the Bipartisan Infrastructure Law, to accelerate work within the North Yuba landscape.” “The North Yuba Forest Partnership is an inspiring group of people working toward common goals of ecological restoration and protection of the surrounding communities from catastrophic wildfire,” said Tahoe National Forest Supervisor Eli Ilano. To address the challenge, the USDA Forest Service and a collaborative group of eight partners within the North Yuba River watershed have been working at an unprecedented scale to plan, analyze and implement what is now the largest “green forest” project in California. Photo courtesy of National Forest Foundation Some of the work already completed within the North Yuba Priority Landscape includes 3000 acres of mechanical thinning, which protects the forest ecosystem and surrounding communities from devastating wildfire in and around Tahoe National Forest. While scenic, these and neighboring Sierra gateway communities are surrounded by forest stands that have become overly dense and susceptible to catastrophic wildfire, insects, disease, and drought. The area includes thousands of acres of forest habitat and is an important source of water to downstream farmers and residents in Yuba County and the Sacramento Valley.

Notice that the family-wise error rate increases rapidly as the number of groups (and consequently the number of pairwise comparisons) increases. The following table illustrates how many pairwise comparisons are associated with each number of groups along with the family-wise error rate: If we have more than four groups, the number of pairwise comparisons we will want to look at will only increase even more. This means there are a total of six pairwise comparisons we want to look at with a post hoc test:Ī – B (the difference between the group A mean and the group B mean) Thus, when we conduct a post hoc test to explore the difference between the group means, there are several pairwise comparisons we want to explore.įor example, suppose we have four groups: A, B, C, and D. ![]() ![]() When we conduct an ANOVA, there are often three or more groups that we are comparing to one another. 05, the probability that we get a false positive increases to beyond just 0.05. The more dice we roll, the higher the probability that one of the dice will land on a “1.” Similarly, if we conduct several hypothesis tests at once using a significance level of. If we roll five dice at once, the probability increases to 22.6%. But if we roll two dice at once, the probability that one of the dice will land on a “1” increases to 9.75%. The probability that the dice lands on a “1” is just 5%. However, when we conduct multiple hypothesis tests at once, the probability of getting a false positive increases.įor example, imagine that we roll a 20-sided dice. When we perform one hypothesis test, the type I error rate is equal to the significance level, which is commonly chosen to be 0.01, 0.05, or 0.10. when we claim there is a statistically significant difference among groups, but there actually isn’t. In other words, it’s the probability of getting a “false positive”, i.e. ![]() In a hypothesis test, there is always a type I error rate, which is defined by our significance level (alpha) and tells us the probability of rejecting a null hypothesis that is actually true. The Family-Wise Error RateĪs mentioned before, post hoc tests allow us to test for difference between multiple group means while also controlling for the family-wise error rate. If the p-value is not statistically significant, this indicates that the means for all of the groups are not different from each other, so there is no need to conduct a post hoc test to find out which groups are different from each other. Technical Note: It’s important to note that we only need to conduct a post hoc test when the p-value for the ANOVA is statistically significant. In order to find out exactly which groups are different from each other, we must conduct a post hoc test (also known as a multiple comparison test), which will allow us to explore the difference between multiple group means while also controlling for the family-wise error rate. It simply tells us that not all of the group means are equal. However, this doesn’t tell us which groups are different from each other. If the p-value from the ANOVA is less than the significance level, we can reject the null hypothesis and conclude that we have sufficient evidence to say that at least one of the means of the groups is different from the others. The alternative hypothesis: (Ha): at least one of the means is different from the others The null hypothesis (H 0): µ 1 = µ 2 = µ 3 = … = µ k (the means are equal for each group) The hypotheses used in an ANOVA are as follows: An ANOVA is a statistical test that is used to determine whether or not there is a statistically significant difference between the means of three or more independent groups. ![]() |
