Channel width plays a big role in Wi-Fi performance. Every wireless environment is different and you need to tailor your equipment to your needs.With 2.4 GHz, increasing your channel width often isn't worth it, and you should stick with 20 MHz.With 5 GHz, increasing channel width can improve performance, but there are tradeoffs. With 5 GHz, if you don't have to worry about interference and all your client devices support it, go with the highest width available.Of course, the rules of thumb above won't always be best for you.

Long Story Short

Getting bandwidth right isn’t always straightforward. With multiple standards and a variety of tradeoffs, it can be hard to keep up with best practices.

The night guard needs to be cleaned daily, with weekly deep cleaning.The same bacteria in your mouth will be transferred onto your night guard after wearing it all night.If your guard is not cleaned daily, the following can occur:<ul><li class="ql-align-justify">Bacteria buildup</li><li class="ql-align-justify">Bad taste and/or odors</li><li class="ql-align-justify">Mold and mildew</li><li class="ql-align-justify">Plaque buildup</li><li class="ql-align-justify">The guard becomes discolored or stained</li><li class="ql-align-justify">Reduced lifespan for your guard</li></ul>

The Why?

The best time to clean is first thing in the morning . If you wait until later, you place it at higher risk for bacterial growth. As it dries, the residue hardens and becomes hard to clean.Simply brush the guard thoroughly with a toothbrush and toothpaste. Brush gently all sides and angles, not just the portion that comes in contact with the teeth. Afterrwards, let it dry completely before storing the clean night guard in its case in a cool, dry place.If in a rush, quickly rinsing the guard with water, but do your best to brush it when you have time.

The Dailey Routine

Clean the night guard with denture cleaner or mouthguard cleaners. Avoid mouthwash that contains alcohol as this may damage the guard.Also, regularly clean the guard's case by washing it with dish soap then thoroughly rinse it off.To deep clean organically:<ol><li>soak in white vinegar for 30 min</li><li>Rinse and soak in hydrogen peroxide for 30 min</li><li>If the guard is starting to smell or turn colors, soak in water and baking soda solution for 30 min</li></ol>Set a timer and do not over-soak in any cleaning liquid as it will damage the guard.

The Weekly Routine

<ol><li>Do not throw the night guard in a dishwasher or boiling water. High heat can warp and ruin the night guard.</li><li>Avoid bleach, since bleach can actually damage the night guard. It can also be dangerous if you don’t rinse all of the bleach off.</li><li>Keep an eye out for any cracks, damage, or uneven wear. Replace the night guard at any first sign of damage to avoid damage to your teeth or jaw. </li></ol>

The Least Square Moving Average indicator allows you to assess the direction of the market movement and its possible reversals.The least squares moving average algorithm plots a regression line on the graph at the current point.(The indicator is based on the least squares method to find the straight line that best matches the data for the selected period.)The LSMA tries to predict the price behavior, what it would be if the regression line continued.

Definition & Fundmenta

<ol><li>Since LSMA is a mathematical line, it can show values that prices have never shown (values higher than ATH).</li><li>LSME is much more responsive than any other moving average. Given that its calculation accuracy will be higher.</li></ol>

Leather is an extremely durable material that is naturally resistant to dirt; however, over time it will get dirty.If leather loses its natural oils and moisture it loses its flexibility and starts to crack.Leather conditioner can help keep leather soft and protected by lubricating the fibres and reducing friction. The conditioner will also help to protect the surface from stains and over time will deepen the colour and enhance the patina.

The Why

Normal leather conditioning needs to be done twice a year but leather that is often in the sun should be conditioned at least three or four times a year.Always test the product on an unobtrusive area of the leather first. Apply the product to a microfibre cloth, never directly onto the leather. Wipe in the product in the direction of the grain and remove any surplus with a clean cloth. Allow the leather to dry naturally, away from sunlight.Any conditioner applied following the cleaning should be done so in very small quantities: too much conditioner can be more detrimental than none at all.

There are three principal forms of conditioner: <ol><li>Conditioning Creams: These products nourish and moisturise and cause minimal colour change. A good conditioning cream will keep the fibre supple and provide some protection to the surface of the leather.</li><li>Conditioning Oils: Neatsfoot oil and lanolin have been used to soften leather for centuries. An inappropriate oil will make the leather sticky and may even cause it to become rancid.</li><li>Wax Conditioners: Wax will not penetrate deeply and nourish the fibres but it does provide an excellent surface protection from water and other liquids. </li></ol>

Different Kinds Of Conditioners

Wet leather needs to be treated while it is still damp, it should not be allowed to dry out. Applying leather conditioner to the damp leather enables the product to seep through the pores and into the spaces left by the evaporating water. If not treated, it could result in leather cracking.Leather will be stained by water, especially rain. Stains can be removed by rubbing the spot with a clean, damp sponge. Allow to dry naturally, never use heat to speed up the process.Wet leather could shrink because the water displaces the natural oils and leaves the leather fibres exposed to the air.

Leather Care When Wet

The following products all achieve four and a half stars out of five on Amazon customer reviews:<ol><li>Leather Nova Conditioner and Cleaner</li><li>Leather Honey Leather Cleaner</li><li>Lexol Leather Care Kit</li><li>Chemical Guys Leather Conditioner and Cleaner</li><li>Meguiar’s Gold Class Rich Leather Conditioner and Cleaner</li></ol>

Which Leather Conditioner Is Best?

<ul><li>Leather peels because it has become dry as a consequence of the absence of its natural oils.</li><li>Leather smelling bad: Leather is a porous, natural material and consequently it can absorb smells such as perfume or smoke. 1) pack in a newspaper 2) Clean with equal parts distilled white vinegar and water 3) Sprinkle baking soda then place in a sealed container for 24h then clean with a dry cloth.</li><li>White marks occur on leather because of water damage, damp or because of salt staining. They can be removed by applying polish, in the case of shoes, or leather conditioner for other items.</li></ul>

WHY SHOULD YOU CLEAN LEATHER? Leather is an extremely durable material that is naturally resistant to dirt; however, over time it will get dirty. How dirty depends on what the leather item is and how it has been used. Leather shoes are likely to get dirtier than a leather bag or leather furniture. Leather exposed to ve

Benford’s law is an observation about the distribution of first digits in unmanipulated numerical data sets. Benford’s law states that the first digit in naturally occurring collections of numbers is more likely to be small than large.

What Is Benford's Law?

In a number set 0 to 9911% of the numbers start with 1. Likewise, with every other digit from 2 to 9.In a number set 0 to 199more than 50% of the numbers start with 1 and less than 6% start with 2 to 9.In a number set 0 to 29937% start with 1, 37% start with 2, and 3.7% each start with 3 through 9.When number sets obey Benford’s law30% start with 1, while less than 5% start with 9.Benford observed that the first digits of naturally occurring multidigit numbers follow a different pattern.

Getting Technical 

Benford’s law can uncover fictitious numbers in random data sets because data manipulated for tax evasion purposes will likely deviate from Benford’s law, and in that case it is supposed that there had been a tax fraud act.The difference between the expected and observed frequencies is determined through use of a chi-square test. A chi-square statistic measures how a model of expectations compares with actual observed data.

Benford's Law and Tax Fraud

The chi-square test has the following steps:<ul><li>determine the expected frequency of the first digit;</li><li>determine the observed frequency of the first digit;</li><li>calculate the difference between the observed and expected frequencies;</li><li>square the difference (to eliminate distortion from negative numbers);</li><li>divide the result by the number of expected frequencies.</li></ul>When the value computed by the chi-square test exceeds a predetermined critical value, it is appropriate to accept the hypothesis of tax fraud.

Using The Chi-Square Method

Carrie Elliot examines Benford's law and considers how it can be used to detect tax fraud.

A human can usually keep focused and actively studying for about 20-30 minutes in one sitting. Interestingly though, it just take a 5 minute break to regain the focus necessary.In a break, it's better to do something enjoyable, take to a friend, listen to music, etc.

Study intervals

Having a reward (even just a small one like having a bear) in mind to look forward to, for each study session, will help.

Reward Systems

Using a library, studying room, office,... will help the brain to focus. One of the most difficult things to do is to just start. Getting in a place that is meant only for studying will help a lot. Also avoid studying in the bedroom, being in the bed makes it harder to resist sleeping.Assign a lamp to be switched on whenever you want to study, this will help teach your brain to focus whenever the lamp is on (remember the lamp must be switched off at breaks, and never be used for something other than studying)

Dedicated study area (Behavior Reinforcement)

The more active you are in your learning, the more effective. The way to learn effectively is first you have to decide what you are learning: facts or concepts? Understanding the name of a bone is a fact, but understanding what it does in the body is a concept.Can you put the concept in your own words? If you can't; you don't really understand it. Either take the time to discover the meaning of it, or don't wast your time studying.

Memorization vs. Active learning

<ul><li>Study groups are powerful.</li><li>Read the whole thing & then reread and understand each paragraph, one by one.</li><li>Sleep well, have a good rest for your memory.</li><li>Write notes during the class, then relook at them right after the class to give it depth. It will not work if you do it 2 hours later.</li><li>Active Recitation: The best way to learn is to teach somebody else. If there's no one, teach an empty chair, or write it out.</li></ul>

Tips to help You Learn Actively

The SQ3Rs MethodSQ3R = Survey, Question, Read, Recite, Review<ol><li class="ql-align-justify">Survey: a textbook is not a novel, so you can go through the entire chapter and survey it. Skim titles, look at pictures.</li><li class="ql-align-justify">Question: you raise questions as you go through the survey, ex: what is X here? what is Y? Doing this will keep you looking for information in the text book while reading.</li><li class="ql-align-justify">Read & Recite: mentioned before.</li><li class="ql-align-justify">Review: give yourself enough time to review what you've studied. We usually make a mistake when we start studying shortly before the exams which leaves us with no time to review what we've studied.</li></ol>

How to Read Text Books

There is always the repeating method (e.g. flash cards), but a better way is to use Mnemonics which consists of:<ol><li>Acronyms: Acronyms help you remember and memorize facts, terms, and idioms.</li><li>Coin Sayings</li><li>Interactive Images: Interacting images help you understand and also connect things together and memorize facts.</li></ol>

Vanity is excessive pride in or admiration of one’s own abilities, appearance, or achievements. There is a fine line between vanity and ego. Ego is a person’s sense of self-esteem or self-importance.Vanity may be the devil’s favorite sin, but ego can be a trader's (or investor’s) worst nightmare.Ego gets in the way of rational, logical, and reasonable conclusions because fear and greed can tug on our egos and cause us to make mistakes.

Vanity & Ego

Human nature is a powerful force, but it deludes us to believe our gut instincts. When the price of an asset falls to a level where an investor or trader believes is a logical, reasonable, and rational low, they perceive the price as a bargain.After an initial purchase, if the price continues to fall, our emotions cause a dangerous impulse. The little voice in our heads (ego) declares that the market is wrong. But it's never wrong.The quest to buy the low in any market has everything to do with ego and little to do with making a profit.

Buying The Low

On April 20, 2020, in the crude oil futures, came to 0$. Who wouldn’t want to buy crude oil at zero? After all, what is the risk?As the history shows, a purchase of the expiring futures contract at zero looked more than ugly at negative $40 per barrel, the April 20, 2020 low.

Example Of Buying The Low

Shorting an asset has the same ego dynamics. The market can take prices to levels on the up and downside that defy logic, reason, and rational analysis. There are many instances where prices rise to levels that make no sense.Selling short and ignoring the power of the trend is dangerous and could be disastrous. Just because a market price rises to a high, does not mean it cannot go higher, a lot higher.

Selling At All Time High

The annual chart of wood price has never traded over $493.50 per 1,000 board (1993 ATH) before 2017.After falling to a low of $251.50 in early 2020 as the global pandemic gripped markets across all asset classes, the price took off on the upside.At $660 in August 2020, it reached a new record high.At $1,000 in September 2020, the price was irrational, and it more than halved in value, reaching a low of just over $490 in October 2020.In May 2021, the price exploded to $1711.20 per 1,000 board before collapsing.

Example Of Selling At ATH

Following trends requires a special skill, which is no skill at all. Ignore expert advice, the news, and any other exogenous forces. The only tool necessary is a simple chart that displays the path of least resistance of the price.The process is entirely objective, while fundamental analysis is completely subjective.James Surowiecki argues that the many are smarter than the few and collective wisdom shapes business, economies, societies, and nations. A price chart is the roadmap of the crowd’s wisdom.

Follow The Trend

Eliminating ego from all investment and trading decisions starts with ignoring the news, experts, and any inputs other than the herd behavior in markets.Prices rise & fall to levels that many believe are not sustainable, following trends allows you to take advantage of their mistakes. Make a conscious decision that you will end the quest to pick a high or low in any market.Ignore those voices in your head that appeal to your ego. Never forget that your view has no relevance whatsoever. Approach markets with a clear risk-reward plan.

Suppressing Emotions are Harder Than You Think

Vanity may be the devil’s favorite sin, but ego can be a trader or investor’s worst nightmare. 

Understand yourself and those around you.

Leave Your Ego At The Door

Because the IRS classifies digital currencies like bitcoin<a href="https://www.cnbc.com/quotes/BTC.BS=-USS"> </a>as property, losses on crypto holdings are treated much differently than losses on stocks and mutual funds, according to Onramp Invest CEO Tyrone Ross. With crypto tokens, <a href="https://www.investor.gov/introduction-investing/investing-basics/glossary/wash-sales">wash sale rules </a>don’t apply, meaning that you can sell your bitcoin and buy it right back, whereas with a stock, you would have to wait 30 days to buy it back.

BTC as a Property

The more losses you can rack up, the better it is for the investor in the long run.“You can harvest an unlimited amount of losses and <a href="https://taxbit.com/blog/cryptocurrency-trading-tax-loss-harvesting-guide/#:~:text=You%20can%20carry%20forward%20capital,each%20asset's%20cost%20basis%20manually.">carry them forward </a>into an unlimited number of tax years”.Because the wash sale rule doesn’t apply, investors can harvest their crypto losses more aggressively than with stocks, because there’s no baked-in waiting period.

Accumulate Losses

Quickly buying back the crypto is a key part of the equation. If timed correctly, buying the dip enables investors to catch the ride back up, if the price of the digital coin rebounds.But be caution that thorough bookkeeping is essential.Be warned, “Without detailed records of your transaction and cost basis, you cannot substantiate your calculations to the IRS”.

Thorough Bookkeeping Is Very Essential

With crypto tokens, wash sale rules don't apply, meaning that you can sell your bitcoin and buy it right back, whereas with a stock, you would have to wait 30 days.
