Info to Know: Admission: Free - A donation box for parking is $2 a day or $20 a year Dogs: Allowed on a Leash Bathrooms: In the Horticulture/Visitor Center Address: 4603 Green Spring Rd, Alexandria, VA 22312 Location: Lat, Long: 38.824471, -77.159254 = Witch Hazel Rd to park on side of the road if the gate to the parking lot is closed Plus Code: RRFR+Q7 Lincolnia, Virginia Website: https://www.fairfaxcounty.gov/parks/green-spring Types of Photography: Landscape, Close Up, and Birds Green Spring Gardens, which sits on 9.5 acres of land, celebrated its 50th anniversary in 2020! Even though the address on the website is 4603 Green Spring Road, Alexandria, Virginia, it is actually on a side street that has no parking or any viable access to their parking lot. The best way to access the Gardens parking lot is from Little River Turnpike, head north on Braddock Road, and turn right onto Witch Hazel Road. Since the Group’s field trips begin at 7:00 AM, but the Green Spring Gardens gate is not lifted until later, photographers park on the side of Witch Hazel Road and take a short walk to the park. Or, in the alternative, if Witch Hazel is full on the weekends, parking is available in the business parking lot next door. There are two main buildings at the Gardens. One is the Green Spring's Historic House, and the other is the Visitor Center. There is also a greenhouse attached to the visitor center with flowers and plants. The field trip here begins at the parking lot, where flowers and birds can be photographed. Next, the Group takes one of the paths towards the Historic House, where there are many different types of flowers, including bleeding hearts, and also where several butterflies congregate. Waterproof shoes can help your feet from getting wet on the grass. Continuing on this path past the Horticulture/Visitor Center that leads to individual gardens. At this juncture, another trail appears that takes you down a meandering hill and across a stream. The trail leads to two small ponds, one has lotus flowers and the other a gazebo. Stay on this path and head toward Green Spring Road. Make a left turn, to head back to the parking lot and Witch Hazel Road. At the end of this field trip, the Group typically has breakfast at JukeBox Diner, 7039 Columbia Pike, Annandale, VA 22003 (jukeboxdiner.com) Bring: Water, fully charged batteries, empty cards, tripod, comfortable shoes Share only your very best, most interesting shots after the field trip, and keep it down to between 5 and 10 photos.

Central Bank Digital Currency (CBDC) With Digital Currency they can: Have a complete government dossier on every detail of your life. Use your purchase history to maintain a detailed social credit score for every person. Provide tax breaks to corporations who hire people with admirable social credit scores. Only grant government contracts to corporations with employees with admirable social credit scores. Adjust health insurance premiums to incentivize people to develop admirable social credit scores. Connect your social credit score with a digital ID to encourage you to look at only approved web sites when surfing the internet. Viewing conspiracy web sites could lower your Social Credit Score and make it difficult to get a job. With their electronic chain around your neck, they can control where, when, how you travel, what food you are allowed to buy etc. They will love the power to only allow you to use your digital money only where they want you to shop and allow you to buy only what they prefer you to buy. Require you to have to have a license to use your money. They will call it a Digital Currency License. Require you to take any vaccine they want you to take to maintain your digital currency license. Tax you in ways we have not even imagined. Adjust your income tax rate based on your social credit score. Use AI to increase your income tax rate if you eat too many hamburgers because they will tell you eating too many hamburgers will increase global warming. This is just one example of many behaviors they might not approve of. Adjust individual prices for different individuals. They will be able to make you pay more per pound for hamburger if you purchased too much red meat during the past 30 days. Require you to buy so many pounds of soy burger for every pound of hamburger to save the planet and increase the profits for the soy burger manufacturers. Turn off the digital money of people they consider to be spreading misinformation. Turn off the digital money of people they consider to be dangerous conspiracy theorists. Turn off your money at 8 PM if they want a curfew at 8 PM Turn off your money in another state if they do not want you to drive to another state without permission. Turn off your money when buying guns or ammo if they do not want you to buy guns or ammo. Turn off your digital money more than three miles away from your home if they want you to stay within three miles of your home during the next epidemic. Etc. etc. etc. From the standpoint of the government, one beauty of digital money is that your money is one “state emergency” away from being the government’s money. All they have to do is to take your digital money out of your Central Bank Digital Account for the “good of all”. It is not as easy for them to do this with physical cash, gold, stocks, or silver etc. Anything they **can** do, they will do. The essence of slavery is control. Digital Currency will enable them to make you, their slave. (in a global digital concentration camp). .

So this month's prompt is more general. I think we can all agree that we are living in "unique" times that require coping skills. I think that one role and/or purpose of philosophy is to help us deal with our daily lives and our "unique" times. So, let's share our feelings and thoughts about which philosopher/philosophy we turn to in order to deal with our crazy events. Who/what helps you stay focused in your daily life and helps you sleep at night. I find that Stoicism with a little philosophical pessimism mixed in goes a long way in helping me deal with what I see as very destructive, fearful and mean spirited public policies at both the state and federal levels. Hope to see you on March 28th!

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
