> cobalt, a very toxic heavy metal Cobalt is neither particularly toxic nor a heavy metal. In fact, it's a part of vitamin B12. You might be thinking of Cadmium, which is indeed a very toxic and nasty metal. In LiPos the heaviest

Well let me ease some of your fears. Lithium batteries are less toxic than most other battery chemistries (including lead acid batteries). The major toxic portion of lithium batteries comes in the form of production, but not the actual mat

Ah shoot, you're right this wouldn't be what I'm thinking. I was thinking of "GC Nepotism" [1]. That's the case where an object in old gen pointing to an object in new gen will automatically promote that new g

Not really heap compression or special, it's just reusing a reference to an object already allocated on the heap. Right now, if I do this LocalDate a = LocalDate.of(2020, 1, 1); LocalDate b = LocalDate.of(2020, 1, 1); A an

Great, and through your effort you can raise a total of 100, maybe even 1000 dollars. Meanwhile while you are willing to give $15 for good data, Koch is willing to spend $15 million for a guy with a degree in fine arts to tell us he's

One of my least proud (most proud?) hacks when working with very large data sets is something like this Map<Integer, Integer> intCache = new HashMap<>(); while (loading) { Integer feild1 = intCache.computeIf

Cheap, not free, and even pretty simple to accidentally fool the GC on the lifetime of these objects. Consider, for example, if you have a log message like this logger.info("Hello {}", myOldObject); if "myOldObject&q

The most surprising allocation pressure I constantly run into is primitive boxing. The JVM does heroics to try and avoid it as much as possible, but when you end up with some primitive boxing in a hotspot the amount of GC pressure that crea

Yeah, I don't love this part of the work. Especially since it's completely exploded out the text of basically everything. I'm also suspicious that the person that generated that text didn't read any of it.

Valhalla can't come soon enough. I've definitely had to change things into SOA in order to eke out performance. My coworkers aren't thrilled seeing `double[] x; double[] y;` but that really is about the only way to get the

Totally agree, but I'm in Java land and cursed to have about the worst case scenario for those things :D

Because you might want to put a breakpoint on that line of code and debug the variables going in and coming out. But further, optimizing in the compiler can preclude future optimizations by the JIT. Giving the JIT more information can make

While the article is interesting, it's the case of a missed optimization by the compiler and (possibly) something that a future version of the compiler will catch. This sort of optimization is one that'd I'd not spend too muc

It's a good rule of thumb that can be quite useful without additional analysis. It's not always the right way to do performance tuning, but I can't count the number of times I've changed an O(n^3) to an O(n) and seen ma

Ktesias wrote of the battle using Persian sources. Though he's considered pretty unreliable. While the sources are all from greek authors, we have 6 different sources about the battle with Herodotos, Diodoros, and Ktesias all writing

It ultimately depends on if there is overriding state or federal law. But yeah, it's something a city can enforce. A small town in Wyoming could do the same and could sue (and probably win) against businesses that do business in that

Important to note, Canaanites have semitic names. So, someone with a semitic name isn't even an indicator that they were a Hebrew, only that they were possibly Hebrew. Which is unlikely. The evidence we have is that Hebrews were a spl

Likely? That's wild. What's the corroborating evidence from ~750BC documenting their existence? Heck, where's that evidence from 650BC?

People wandering in the desert for 40 years, or even 1 year, leave traces. Especially when it's thousands of people (at a minimum). The Hebrew language came long after the exodus. We have no earlier records of it that aren't wri
