Kind of - the point remains. Lombok requires to alter the compiler (hook into), not (just) the annotation processing, itself. I'd be okayish if Lombok was a mere post compilation/enhancement too, but it isn't. It's a pe

A whole hour of runtime would be mean 1C discharge. 80V (which is likely 72V, but in the US it's ok to label the max voltage rather than the actual one) is made of 20 Li-Ion batteries in series. Lets say 2 in parallel, so total 40 batt

I don't believe that part - the ones shown in the picture/videos are brushless motors, quite efficient (90%) and really silent on their right own. The noise comes from the need to move air (and the noise is just air waves), along

There are different types of mowers - push (usually 4cycle), push+self propelled, riding one(s), then 2cycle scythe types, and then trimmers and brushcutters (spinning blades). Those options (more or less) are available battery powered, too

I reread it - it says 40% reduction, that's -7dB... I can believe that part. Edit: checked DCBL772X1 - it's listed 68 dBA - that's not necessarily loud, so if they managed -7dB, massive props to them.

Lawn mower robots do the trick quite nicely actually.

That is battery (li-ion) powered, so it's already quieter to begin with.

Unfortunately the article is very poor on details. The sound from the video is insufficient to tell. Personally, I'd be quite excited to see what are the changes engineering wise. I bet it'd make a proper addition to BOLTR. I stil

Unless you stumble on it. Other than that - leaf blowers are not used only in gardening work.

That looks like a trivial optimizaiton / transformation. I am still quite puzzled how much work has gone into compilers, static code analysis, guided compilation (naturally comes w/ JITs, too). Yet, database optimizers of pretty m

not with java - it needs a path. Of course if you have a ram disk (e.g. /tmp) it'd do the job.

I'd take mutability for an array as given. If I wanted functional style data structures I'd use them. Personally I see zero reason for immutability of an array, imagine every add/push had to create a new instance of the said

I disagree entirely on the 'reasonable' implementation part. If something was that big the memory was already allocated, and it's not unlikely to grow again. Shifting memory/resources within a lifespan of a particular in

It lacks any concurrency handling, even though there is a section about it. The attempt to use some, e.g. RefCountedObject, performs a proper transgression - 'data' field being non-volatile and modified within a synchronized block

One note - if you ever have to write middle ware (or a garbage collector), avoid any code calling custom implementations like hashCode/equals. A variant of Collections.newSetFromMap(IdentityHashMap...) should replaces all Sets in the e

bit late on "by design" party - java 'binary' (not source, which is easier) compatibility is an exceptionally important feature. E.g. changing method signature like void x(int val) to void x(long val) does break the

That much it was all about JSP/XML and stuff; J2EE too. JDO came soon after too. The applets did exist and (javax.)swing was a thing - but it was far from the focus... and of course Java was still considered slow.

You're a terrible developer if some project manager tells you to disable paste... and you listen to. I know it's easier to pick jira task, implement them feeling you're making the world a better place.

That's really pretty much everything, google knows you may think you have breast cancer -- email, gender, age, visit pages, etc. Certain sites and information classes/types are not just like the rest of 98%.
