Another quick method is using ORDER BY until the error appears, then you can infer the column count without relying only on NULLs

SQL injection! 💉 After finding the number of columns using the NULL trick, you can take it a step further and identify which column takes which data type. Swap 'abc' into one position at a time. The one that comes back without an error is your string column, and that's where your data goes. Want to practice this technique? Hack our FREE labs! 👇

You are out to eat with friends and get ready to pay your bill and you notice the tip percent options are not adding up, so you get out a calculator and check the numbers. The amount for 20% is actually adding up to 28%🤔 Do you go ahead and use the restaurants numbers or do a custom tip?

In Yoshi's Island, it is possible to obtain an extremely corrupt object called a Null Egg, which has a variety of glitch effects. One of them is that taking the Null Egg into the Naval Piranha battle will cause the boss to assume a psychedelic, color-changing rainbow appearance.

One of the coolest ideas in mathematics is the estimation of a shape's area by throwing random points at it. Don't believe this works? Check out the animation below, where I show the method on the unit circle. (Whose area equals to π.) Here is what's behind the magic:

Painting faces is one of the parts of the miniature I enjoy most because it is the soul of the mini. This is one method I use to paint faces from time to time, and it gives good results for the time spent. In the end, you have a comparison with a 1h to 1h30 face, worth the effort

PARTICIPATION - NOT DEMORALIZATION! The answer is not to "burn it all down", check out and give power to Democrats. The answer is to COMMIT to being a part of the long-term solution. Our country's problems cannot be fixed in one election cycle. Candidates aren't perfect, but that's what primaries are for. This is a long process that is winnable if we stay focused. It will take the better part of a decade plus of consistent participation and engagement to correct course. Resist the demoralization op, lock in, and let's get to work.
