![]() ![]() Kotlin supports nullability as part of its type System. Well, Enter Kotlin! Nullability and Nullable Types in Kotlin Wouldn’t it be nice if we could detect possible NullPointerException exception errors at compile time itself and guard against them? NullPointerExceptions are Runtime Exceptions which are thrown by the program at runtime causing application failure and system crashes. If you have been programming in Java or any other language that has the concept of null reference then you must have heard about or experienced NullPointerException in your programs. ![]() Sir Tony Hoare, The inventor of null reference This has led to innumerable errors, vulnerabilities, and system crashes, which have probably caused a billion dollars of pain and damage in the last forty years. But I couldn’t resist the temptation to put in a null reference, simply because it was so easy to implement. My goal was to ensure that all use of references should be absolutely safe, with checking performed automatically by the compiler. At that time, I was designing the first comprehensive type system for references in an object oriented language (ALGOL W). It was the invention of the null reference in 1965.

Part of Young People's Concert: Inspiration! In a concerto, composers write the soloist’s part to be especially flashy and technically difficult to perform so that the soloist can really show-off his or her skills. The soloist at this concert is a member of the NSO. Such a composition is called a concerto, a work that features the talent and skill of a solo performer. Sometimes composers choose to write music that features one instrument over all others. In the “Presto” (meaning super-fast) section of “Summer,” Vivaldi uses music to tell the story of a shepherd and his flock caught in a sudden The summer rainstorm. The air is almost at a standstill, the birds chirping away lazily until a breeze gathers up, whipping the warning of an imminent storm. ![]() Italian composer Antonio Vivaldi was inspired by nature and his own poetry to write a series of violin concertos to express the four seasons.

With the Background layer selected in the Layers palette, lasso his head, then hit delete. We’re doing this so when he nods downward, another head won’t appear behind it. Turn that new layer off, and on the base/background layer, remove the background wall behind his head. This copies the selection to a new layer above. In other words, don’t waste time trying to select his white hair out from the cream-colored background. This is going to be a 120-pixel image when we’re done, so accuracy is not that critical.

Repeat this with “DESI”, “DES” and so on until the text is tightened up evenly. Since we want the “N” of “DESIGN” and the “T” of “TEXT” to stay lined up, move the slected letters in towards the right by a space or two. To fix the kerning of “DESIGN”, we want to drag a box around “DESIG” - excluding “N”, the last letter - with the Selection Tool (V). This will make it so we can click on each letter on its own.Ĭlick and drag a box around “TEXT” with the Selection Tool (V) to select just that word, and then move it up closer to “DESIGN”. First, we need to ungroup the text, so go to Object > Ungroup (Shift + Ctrl/Cmd + G). The kerning (space in between the letters) and leading (space in between the top word and bottom word) of the text should be adjusted to make everything fit tighter. Step 3: Adjusting the Kerning and Leading Using your Selection Tool (V), click on the text and then go to Type > Create Outlines (Shift + Ctrl/Cmd + O). Now we are going to covert the text to shapes so it will be easier to work with. The font I am using is Adelle Basic Bold, but you can use another similar font if you prefer. You can adjust the size of the text by opening up the Character Panel (Window > Type > Character or press Ctrl/Cmd + T). This will give us the shape we are looking for. We are going to start off by typing out some text.Ĭlick on your Type Tool (T), click and drag a box on the artboard for your text, then type out “DESIGN TEXT” in two lines.
