![]() With my brayer loaded with ink, I very lightly rolled it over my letterpress plate. I then rolled it out with my brayer until I had a very, very light coating of ink on the brayer. I took a small amount of ink from my can, mixed it until it was smooth on my first acrylic piece with my ink knife and then transferred a very small amount onto the second acrylic piece. I got a 6in soft rubber brayer and was very glad that I did. The brayer that comes with the kit is also so small that is it absurd. Honestly, the piece of acrylic that came with my kit was ridiculously small and I would have saved myself some headaches if I had used something larger since I barely had any room to hold it. I had the one that came with my kit and then I used the back of one of my quilting templates for the other one. When printing you need to use a very, very small amount of ink so you should have two acrylic pieces, one to work some ink until it is soft with an ink knife and the other to roll out with your brayer. ![]() I also liked the fact that rubber ink was slow drying to make clean up and printing easier. Honestly, it was expensive but now I have a lifetime of navy ink since it comes in a two pound can. I choose to order deep navy blue rubber ink from Boxcar Press. I aligned my plate on the top board using the grid lines. The letterpress kit is basically two hinged acrylic boards that you crank through a die cut machine. I saved the blue film to reapply after I was done. Next, I pulled the blue film off the plate to expose the sticky backing on my invitation plate. ![]() ![]() The reply card is on the left and my invite is on the right. I used a regular scissors to cut apart the elements from each other. Below is a portion of the plate that I received with my invitation on the top right and the reply card on the bottom right. They also take PDF and EPS files as well. ![]() I simply created a log-in and uploaded my Adobe Illustrator file. Honestly, I realized after getting my plate I could have packed things together a little more tightly than I did. Since you pay for the total area of the design and there is a minimum size I decided to fill up the blank spaces with other words like "Happy Birthday" and "Thank you" as well as some cute icons for later use in card making. For fonts I used Bickham Script Pro for our names, Times New Roman in italic for "and" and "reception to follow" and Copperplate for the rest of the wording. My first step was to create a design for my invitation and reply card on Adobe Illustrator. With renewed enthusiasm, I decided to go for it and ordered a custom letterpress plate from Boxcar Press. At first I was a little discouraged since the reviews weren't so great, but I found that some people had success using modifications with a tutorial from Boxcar Press. I did a little searching around on the internet and came across an at home option with the Lifestyle Crafts Letterpress Combo Kit. I looked at my local paper/bookbinding shop to try to do a traditional class where you set your own type, but nothing was available in the time frame I needed. I love how letterpress looks so I really wanted to try making my own letterpress wedding invitations. ![]()

![]() I suppose people who suggested Microsoft Word and Office 365 are right somehow, that is the most cross platform, or you may also try Simplenotes, which has no audio features.

What apps would everyone in this wonderful forum suggest? I realize I could probably use the Voice Memos app for audio notes, but I would prefer my notes to be in one place. That app is available on iOS, macOS, the Apple Watch, and as stated previously, windows.Īnother requirement each candidate app must have, is that it be able to open the Evernote export format, including Notebooks. However, you can write something down in notepad, save it to the notebooks folder in dropbox, then have it available on your other devices. I recently heard about an app called Notebooks, which I’ve actually used previously, but the windows version is not accessible at all. I am hoping that Apple adds the ability to make audio notes in iOS 16, but that may just be wishful thinking. I have a bunch of stuff in the notes app on my iPhone, but I don’t know if there’s a way to make that available on a Windows PC. I would like something that allows both audio and text notes, as well as images, and links with previews.

Aluminum Hot Surface Standard Test Method for Corrosion of Cast Aluminum Alloys in Engine Coolants Under Heat-Rejecting ConditionsĪSTM D-3306= Automotive service interval. What does that mean and is that all you need to know.ĪSTM D-4340 = Test for new coolant. When you see most coolants they will say that they pass the ASTM D-3306 and ASTM D-4340 standards. There is a difference between performance requirements and chemical requirements. Now that we know all that can’t we just poor any coolant into the car that says it meets all the requirements to be used in any car. OAT coolants reduce the effects of ECD because the OAT coolants conduct less ECD then the older coolants. ECD can be attributed as the cause of many premature coolant system failures. This electrical charge degrades both rubber and metal parts in the cooling system from the inside out. electrochemical degradation or ECD is where the motion of coolant and water through your engine creates an electrical charge similar to a galvanic battery. One of the things that older cars and coolant had issues with was the fact that older coolant wasn’t very helpful in preventing electrochemical degradation. So the new OAT is longer lasting safer and has some added protection that older coolants didn’t. The OAT coolant is much safer for children and pets. Now if you spill your G12 OAT coolant you don’t have to worry about killing your neighbor’s dog. It is made from a propylene glycol base which makes it less poisonous than the older coolant and being less toxic and poisonous it is much less harmful to the environment. This helps give it that extended life extended mile protection ability. Switching over to the new G12 or OAT style coolant has lots of advantages the OAT coolant has very similar corrosion protection as the older green coolant but its slower acting and is more stable resulting in it being slower acting and taking much longer to break down. G12= Organic Acid Technology or OAT for short. The OAT name is also seen when referred to as Dex-cool. Organic Acid Technology = propylene glycol. In comes Organic Acid Technology or OAT biased coolants for short. The big requirements of the coolant come down to the classification of them and how that changes things. The way Audi solved these issues for the bigger requirement was with a different blend of chemicals using a new classification. People wanted longer distances between needing to service oil and coolant. As the motors became more demanding the gaps between servicing the motor and the oil needed to change as well. This was not only bad for the motor it was bad for some of the motor components. Most of the time people would keep the coolant in way past its normal life. The older style of coolant (green stuff) had a shorter life then most people understood. As the years have moved on and the motors have become more and more complicated with higher requirements things needed to change. ![]() You can usually tell if the mix is too strong or too diluted by looking at the color consistency. There is also color added to help in recognition of leaks and to help in identification while helping give an idea on proper mixing. There are also other chemicals added to help in lubrication, corrosion inhibitors and others for buffers. To better understand why come coolants and mixes work and others don’t lets explain what coolant is and why getting the mix wrong can lead to damage.Īll coolants have chemicals added to help in pulling heat away from the motor to (cool ie coolant) cool the motor and there are chemicals added to assure the fluid won’t freeze (antifreeze)So this is why we call it coolant or antifreeze. But does that mean they will work and be ok in your car. What you will see often is them saying they meet or exceed the standards of the G12 coolant. You see lots of coolants saying that they are compatible but are they. Here are a couple suggestions that have been found to be in line with what G12 coolant seems to provide. They are recognized as a direct replacement for All Audis. If you can’t get to a dealer what choice you do you have? Look into Pentosin coolants.

These easy-to-make DIY firepit ideas are here to make your summer the best one ever: whether you want to cook your food over an open fire or just snuggle up while you drink some beers, these simple projects will make a great addition to your yard. The components, the burner, and the seating of this fire pit are all below-ground. Sunken Fire Pitsįire pits with sunken bases have a unique look. If you plan to use a linear fire pit as a fire table, make sure your flame size is appropriate if it is too big, guests won't be able to stay close. Having less width than round or square fire pits, they are more accommodating for sitting, and more conducive to socializing. In addition to its contemporary appearance, a linear fire pit offers versatility. It has the advantage of conserving more space, but it may be more difficult to fit as many people around the fire pit. Modern fire pits are square or rectangular in shape. Curves are also incorporated into their designs to complement landscapes. Traditional round fire pits look great in many spaces. We can make some recommendations if you do not have a specific shape in mind: Round Fire Pits Fire Pit ShapesĪny fire pit will look good if it is done correctly, regardless of the shape.

Still, you should be aware of a few things. Personal preference will play a greater role in these decisions. You will just need to determine your fire pit size and shape after examining your budget, fuel supply, and usability. The requirements of a homeowner who builds a fire pit in their backyard do not match those of a construction contractor designing fire pits for a business.īefore purchasing components for your fire pit, it is a good idea to determine if there will be any restrictions. Use CasesĬonstructing your fire pit should take into account how and who will use it. But the size and shape of your pit will be limited.

Consult experts before relocating a gas line because it may be the most expensive part of your fire pit. During this part of the process, it's a good idea to work with a professional.Ī gas line should always be installed correctly the first time there's nothing worse than laying a gas line before determining what type of gas supply you need. Fuel Typeįueling your fire pit with propane or natural gas can be tricky no matter the kind of gas you are using. Avoid this hassle all together by checking your local codes first. It is a costly mistake to purchase a fire pit, install components, and then have to alter the design afterwards because of local codes. Guidelines are generally simple to follow - if at all they are given - but we should always be on the lookout for any unknowns. You should review any local codes related to fire pit construction before starting your fire pit planning process. If you plan to do more than a small propane tank connection, you will need to hire a professional gas technician.

The upgrade process involves an environment downtime that can take up to 2 hours to complete depending on the environment size and can be performed on demand at a time that best suits you. By upgrading, you can take advantage of the latest capabilities of the Apache Airflow platform and maintain compatibility with new features and best practices like data-driven scheduling and new Amazon provider packages released in Apache Airflow 2.4.3. You should consider upgrading your Apache Airflow version on Amazon MWAA if your existing workflows can accommodate the change and a new version is available with features or improvements that align with your use case. Finally, the newly created metadata database is upgraded, effectively completing the transition to the new environment. Subsequently, all Apache Airflow components-web server, scheduler, and workers-are upgraded. To learn more about in-place version upgrades, refer to Upgrading the Apache Airflow version from Amazon MWAA documentation.ĭuring an upgrade, Amazon MWAA first creates a snapshot of the existing environment’s metadata database, which then serves as the basis for a new database. ![]() You can also use the UpdateEnvironment API and specify the new Apache Airflow version to trigger an upgrade process. ![]() On the Amazon MWAA console, simply edit the environment and select an available Apache Airflow version higher than the current version of your existing environment. This feature is available in all currently supported Amazon MWAA Regions. You can upgrade your existing Apache Airflow 2.0 and later environments on Amazon MWAA with just a few clicks on the Amazon MWAA console, by using the Amazon MWAA API, the AWS Command Line Interface (AWS CLI), or by using tools like AWS CloudFormation, the AWS Cloud Development Kit (AWS CDK), or Terraform. Upgrading your existing environments on Amazon MWAA is a straightforward process. In the event of an upgrade failure, Amazon MWAA is designed to roll back to the previous stable version using the associated metadata database snapshot. Amazon MWAA manages the entire upgrade process, from provisioning new Apache Airflow versions to upgrading the metadata database. The newly introduced in-place version upgrades by Amazon MWAA provide a streamlined transition from your existing Apache Airflow version 2.x-based environments to newer available Apache Airflow versions. In this post, we provide an overview of the in-place version upgrade feature, explore applicable use cases, detail the steps to use it, and provide additional guidance on its capabilities. This process was error prone, manual, and involved additional costs to maintain two separate Amazon MWAA environments until you could verify the new and decommission the old. ![]() If you also needed to preserve the history of DAG runs, you had to take a backup of your metadata database and then restore that backup on the newly created environment. This involved creating a new Amazon MWAA environment and then migrating all of your configurations and Directed Acyclic Graphs (DAGs) to it. Until now, if you wanted to upgrade your Amazon MWAA environment to a different Apache Airflow version, you had to follow the Amazon MWAA environment migration instructions. You can now take advantage of the latest capabilities of the Apache Airflow platform without having to create an entirely new Amazon MWAA environment. This enhancement allows you to seamlessly upgrade your existing Apache Airflow version 2.x environments to newer available versions while retaining the workflow run history and environment configurations.

On each roll, each of the numbers-1, 2, 3, 4, 5, 6-is equally likely to appear. For example, you may wish to think of rolling an ideal die. Simply said, we should not be able to use the numbers that we have seen to predict which number will come next or to restrict the possibilities. Most of us already have an intuitive notion of what random numbers are, but, as we'll see, this is a difficult question to answer precisely. The approximate area of the circle is then the area of the square, 4.84, times 1308/2000, which is 3.16536 (the exact area is, of course, ). The figure below shows 2000 points randomly placed inside a square whose sides have length 2.2, 1308 of which lie inside the circle. The percentage of points that lie inside the circle should approximate the ratio of the area of the circle to the area of the square. We could place the unit circle inside a square of known area and randomly add points to the square. For instance, imagine that we do not know the area of the unit circle. Random numbers are also used by so-called Monte Carlo methods to obtain numerical approximations to problems that may be too difficult to solve exactly. For instance, a bank that operates a network of ATM machines may wish to test its software by simulating the actions of customers accessing their accounts at random times through random machines. Random sequences of numbers are also important for simulating real-world phenomena. In other words, the days were not ordered randomly, and a more mathematical solution was proposed for subsequent years' lotteries.Ĭurrently, random numbers are used to form encryption keys when information needs to be passed securely, say, across the Internet. A statistical analysis later found that, because they were placed in the bin later, days toward the end of the year were more likely to be drawn. Young men born on those days drawn first were more likely to be drafted. In 1969, the days of the year were ordered by drawing pieces of paper, each with a day of the year written on it, from a bin. Some readers may remember the draft lottery used during the Vietnam war. Of course, many states run lotteries that use a sequence of random numbers to determine the recipients of huge amounts of money. For centuries, people have used randomness-a coin toss, for instance-to make important decisions. There are many reasons why we might want to do this. We will focus on constructing random sequences of numbers. Surprisingly, we will see that it is difficult to create random behavior (in fact, the words "create randomness" may sound a little jarring) and to determine when we have successfully done it. This article, however, is about how mathematics may be used to create, or at least simulate, randomness, the lack of patterns. It is often said that mathematics is about understanding patterns and that these patterns are what makes mathematics beautiful. The generation of random numbers is too important to be left to chance.
