![]() ![]() Similarly, since the start_date argument for the DAG and its tasks points to the same logical date, it marks the start of the DAG’s rst data interval, not when tasks in the DAG will start running. What about start_date ? According to documentation: And according to Airflow’s official document:Ī DAG run is usually scheduled after its associated data interval has ended, to ensure the run is able to collect all the data within the time period.įor example, a DAG with schedule 30 22 * * *, you can clearly see in the screenshot: – data_interval_end: the end of the data intervalĭAG run time: this is the actual DAG execution time. – logical_date / data_interval_start: this was used to be called execution date until Airflow 2.2, but as the value indicates thestart of the data interval, not the actual execution time, the variable name is updated. There are two values associates to the concept: For example, if you define the schedule with 30 22***(22:30daily),thenyourdataintervalwillbefrom22:30 to the same time next date. data interval: Data interval describes the time range between two DAG runs.a DAG run will only be scheduled one interval after start_date: start date defines when your DAG will run for the rst time.There are several concepts are important if you wish to understand when your DAG will be scheduled. Why? In this article, we will mainly discuss the case when you set your schedule with a CRON job (and some cases also applies to a preset) Data interval, logical date, run time But sometimes we found it not align with our expectation. Once we have our schedule ready, we have an expectation on when our Airflow DAG will run. This is also a new feature introduced since Airflow However, this is not going to be part of this article □ģ. This provides more advanced scheduling possibilities, for example, if you want to “skip” some certain runs. ![]() “Timetables” is a new concept introduced in Airflow 2.2. But what most commonly for more customized schedule is CRON job. A preset provides easier, human readable schedule like. Schedule interval by default is set to None and this is also the case when you use manual or external trigger to the DAG. Schedule interval: to set your DAG to run on a simple schedule, you can use: a preset, a cron expression or a datetime.timedelta.The key component here is Airow scheduler: Airflow scheduler monitors all tasks and DAGs, then triggers the task instances once their dependencies are complete.Īirflow scheduler monitors all tasks and DAGs, then triggers the task instances once their dependencies are complete.įor a scheduled DAG to be triggered, one of the following needs to be provided: Airflow schedulerĪpache Airflow is a powerful tool helping you to orchestrate and schedule your data pipelines. The code snippets included in the article are tested on Airflow 2.2.5 + Composer. Why is a DAG not triggered when my scheduled time arrives? Why a DAG is not triggered at all saying “the task start time is later than execution time”? My CRON job ranges from hours to months, how I should dynamically set up the start time? I asked myself all these questions when I was working with Airflow, and here I just want to make it a record of my understanding. It’s still always confusing the first time you start with Airflow. ![]()

![]() Unfortunately, the mouse wheel scroll does not seem to work, for some reason, which means that you’ll have to do it the old-school way. In order to surf through the titles, all you have to do is scroll up and down. To begin with, you are greeted by a small panel featuring every Solitaire game available in the collection. In fact, you have hundreds of options at your disposal, which practically translates into endless possibilities and many lost hours. Regardless of your favorite version of Solitaire, the application at hand should contain it, maybe even together with three other similar variants. Pretty Good Solitaire is a collection of Solitaire games, ranging from the classic FreeCell, all the way to obscure variations played in remote parts of the world. However, it’s the kind of game that lets you think about other things while playing it, so you can relax and score a couple of points at the same time. The game itself is not that complicated, which means that it probably shouldn’t captivate anyone’s attention for more than a couple of hours. Also works when you don’t have a data signal so you can play it all the time.We all know how addictive Solitaire can be, especially when there’s work to be done. Love this game! I have put it on multiple devices and love how many different games there are to play. I do this with any game that has a distracting banner ad. To everyone freaking out over the ads: I avoid them by turning my data off before I even open the ap. I play it at night to wind down before bed. This game is a staple on every phone I ever buy. How can I get the older version back? I don’t think I’ll be playing this one much. I feel like I have to hold the phone backwards to play. The game score is positioned wrong, the entire layout is wrong. Ads are muted but still play loud, not to mention the old version was ad free. Had my phone reset due to issues and got the updated version. I hadn’t updated this app in 2 or 3 years. Was fun until they put in more ads, now they have one before every single game. Worked well for many months, one update and it’s completely unstable. Games are great the ads are really really annoying turn the sound off in the game and you still get lots of loud obnoxious ads that the sound still pops through unfortunately makes it my last resort Please keep the toolbar option up at all times, and I will give you 5 stars. Love the variety of games and customization. The only thing I don’t like since the recent update is the tool bar doesn’t come up all the time, and I have to keep reopening the entire app and go through two ads just to backspace. I love this app! There are so many different games. Klondike 1 Unlimited (Draw-1, unlimited passes)Ĭheck out our website at for a complete list of our solitaire games with rules and screenshots.

Real data is varied and will contain characters that may not play nice with your code, such as apostrophes, or unicode characters from other languages. When you demonstrate new features to others, they'll understand them faster. When your test database is filled with realistic looking data, you'll be more engaged as a tester. Worse, the data you enter will be biased towards your own usage patterns and won't match real-world usage, leaving important bugs undiscovered. ![]() If you're hand-entering data into a test environment one record at a time using the UI, you're never going to build up the volume and variety of data that your app will accumulate in a few days in production. In production, you'll have an army of users banging away at your app and filling your database with data, which puts stress on your code. If you're developing an application, you'll want to make sure you're testing it under conditions that closely simulate a production environment. Paralellize UI and API development and start delivering better applications faster today! Why is test data important? With Mockaroo, you can design your own mock APIs, You control the URLs, responses, and error conditions. By making real requests, you'll uncover problems with application flow, timing, and API design early, improving the quality of both the user experience and API.

Finally, here is a short YouTube clip of the Whirling Hose Pump.If you and your friends have two hosepipes and buckets, you can have a Whirling Dervish Hosepipe Race: who can drain their bucket first?.Can you pass the hose to a friend while still whirling and jetting water out?.How long can you keep that hosepipe whirling? Can your friends get a ‘bucket relay’ going, continuously refilling the bucket as you whirl?.What about using a rigid tube going up from the bucket, with hosepipe at the top? That way you can stand up and get a good whirling action going without an assistant.What about trying with a rotating joint on the hose? Some hose reels have them.Put a nozzle on the whirling end and then try different settings on the nozzle: can you get a spray or jet?.Image credit: Neil Downie Some Lockdown Challenges A hundred kiloPascals, 15psi in old money, is possible in theory. The water pressure you get goes up as the square of the speed of the end of the hose, so using a longer hose and whirling faster should get a good pressure going. With a longer hose - standing up to get a good whirling action - and no valve, the water will go slooshing out! Your friend keeps their end of the hose in the bucket and then takes their thumb off underwater once you have got going. Your friend must hold their thumb over the end in the bucket to keep the water in once you have filled the hose. What about a human thumb valve? Persuade one of your compadrés to join you. Can you do it without the valve? The valve is helpful, because it keeps the hose full while you get going, stopping the water going back into the bucket, but it does slow the flow. Once you have mastered getting the Whirling Dervish flowing, try out other things with it. You’ll be surprised how quickly the water gurgles out of the bucket. With a bit of luck, your audience will get a nice cooling spray as the whirling hosepipe end passes them. Maybe a little Vaseline or hand-cream will help the hose squirm around in your hands nicely. Let the hose rotate in your hands so that it doesn’t end up twisted. Now let your thumb off and swing the hose around, keeping the valve end in the bucket and swinging the hose as fast as you can. Put your thumb over the end to keep the water in. Or if the hose and water are clean, suck on the end and then hold it low to siphon water in, trying not to swallow any spiders than come out with the water. You can hold up the end of the hose and use a funnel and jug to fill it. Now put a large bucket of water in the middle of the garden, put the valve end in the water and get that hose filled up. These usually go on the tap, to stop water from the hose going back up into the house water. Put a one-way ‘check valve’ on one end – not essential, but it does help quite a bit. Take a piece of garden hose - a heavy grade is best - 2.5m to 4m long. ![]() ![]() Can you make it to the island before the boat fills up and you sink beneath the waves?

You can send a reminder to customers when their payment is past due, or just email the invoice with a link to various online payment options. Like GnuCash, QuickBooks Online offers excellent invoicing capability, so you can customize an invoice, attach bank account or credit card numbers to an invoice for immediate payment, and make an invoice recurring. QuickBooks Online's dashboard offers an overview of your business. QuickBooks Online offers many of the same features as GnuCash, and it also includes a summary dashboard that gives you a nice snapshot of your business. The product also offers limited payroll ability, though you would likely be better served by using a third-party payroll application. One of GnuCash’s best features is its comprehensive budgeting capability. Both customer and vendor details can be managed in GnuCash, giving you the option to assign a currency type for each customer, assign billing terms or a discount, and assign a credit limit as well. When payment is received, you can post it from the open customer account. ![]() The A/R feature in GnuCash is just as impressive, with the ability to create a customer invoice, adjust pricing levels, offer a discount to customers, and calculate sales tax. GnuCash’s main screen offers a list of accounts and current balances. GnuCash uses traditional accounting terms such as Accounts Payable (A/P) and Accounts Receivable (A/R) instead of the current terminology such as bills, sales, and invoicing. It may also be useful if you’re a little familiar with accounting terminology prior to using GnuCash, though there are resources available to help you. GnuCash is the perfect fit for sole proprietors who are more comfortable with an on-premise application. QuickBooks Online is a nod to the business owner who wants to access his or her business data at any time, from any place, and also wants access to the hundreds of apps available. GnuCash is very reminiscent of more traditional accounting software applications and offers solid functionality behind a nondescript home page. GnuCash and QuickBooks Online are both designed for small businesses, but that’s where the similarities end. Not only suitable for growing businesses, QuickBooks Online is also a good fit for sole proprietors and micro-businesses that need a scaled-down version of a solid accounting application. ![]() ![]() ![]() You will find a variety of people ranging from drummers to industry specialists to drum manufacturers.

It looks especially striking next to shrubs with red to purple foliage, such as the many ninebarks on the market. Pair it in the foundation planting with Hydrangea paniculate, which blooms in mid- to late summer, or with other shrubs with foliage colors that will contrast with the silver. It is propagated via softwood cuttings and is protected by a plant trademark. It is best grown in a site that gets about six hours of direct sunlight daily. Researchers in Canada observed it to be a favorite of honeybees, bumblebees, syrphid flies and some butterflies.Īs with most Salix, it tolerates moist soils but does not require them. Iceberg Alley is a male plant, which produces pollen and nectar. In spring, it produces a pretty silver catkin with red stamens that can be cut for early spring decoration. If that’s the case, prune away, as it tolerates pruning well. It requires little pruning, unless you want to control the height or spread. At maturity, it’s 3 to 5 feet tall, with a spread that is slightly larger than the height. You could even use it as a dramatic backdrop to your perennial garden. Iceberg Ally sageleaf willow is relatively small, so it will fit in urban yards and foundation plantings. The silver is apparent from the moment leaves emerge in spring through autumn, when they turn yellow (unfortunately not a spectacular yellow) and then eventually fall off. As you can see in the photo, the leaf is longer than it is wide. The very textural foliage feels hairy and soft, and has a lovely silvery hue. Hardy to USDA Zone 2, this shrub will work for all northern gardeners. This little gem of a shrub was discovered at the Memorial University of Newfoundland and Labrador Botanical Garden in Canada. That has all changed with the recent introduction of a native sageleaf willow cultivar called Iceberg Alley ™. We have some great silver-leaved perennials, such as Artemisia ( ‘Silver Mound’ and ‘Valerie Finnis’) and Stachys (lambs ears), but not a woody shrub. Until recently, we’ve not had shrubs with silver foliage. Whether it is the reds or purples of ninebark, the chartreuse of spirea or sumac, or a great variegated dogwood, foliage can brighten up our gardens all season long. Discover More Information On Iceberg Alley® Sageleaf Willow. Many recent shrub introductions have offered northern gardeners colorful foliage to accent their gardens. ![]() |
