similar youngsters anti sj stars includes @gogreen18 n @shoe0nhead . They typically don't have much knowledge (e.g. professors of subjects). but lacy green is at least “sex expert” in the mass edu sense, and shoe0nhead is actually quite funny, as comedian.

Roaming Millennial is a pretty chick. she rose slowly of as one of those anti sjw. They, typically have 0 content. They get followers due to incessant anti sj posts. Also, since RM is a pretty girl, she gets followers for free.

fking roaming millennial liking random shit on twitter. just unfollowed. xah tip: if you want to be popular or run business on twitter, don't like things not very on topic for your readers.

twitter has this nasty thing, of showing tweets someone liked. you can't turn off, other than on each post click “i don't like this tweet” on each. twitter does that to gather personal data about you, so twitter can sell it.

most hip love of lisp features r wrong.
• macros complicates code logic, harder read/write.
• symbols vs string. symbols pollutes obarray.
• advice complicates code logic, thwart expectation, harder debug.
• lisp read syntax ≈ useless. hobs progress in builtin parser.

in programing languages, uncommon features are traps for hacker types. Hip coders form undue obsession about 'em. e.g. symbols, macros, read syntax, advice. of such is monad, currying. Unusual features is also cult brewing.

i will not be setting google as default. i rather be inconvenient than get politically biased result from google. i'll just goto google manually when needed.

after using for half a year now, it is decidedly inferior to google search.
for popular simple search queries, it works fine. But if you are looking for anything weird or uncommon, google is better. i wonder how bing's doing

Xah Math Input Mode. New version. updated for emacs 26's ucs-names change. Now selection on unicode name works again.

@xahlee tried now in Python 3: concat vs. join is about 60 ms vs. 45 ms on my example. So yes, it's not "as fast" but not a magnitude slower as it's claimed. I'd say, fast enough to never actually care unless proven to be a bottleneck in a particular piece of code.

26 change. 「ucs-names」 was alist, now it's hash table. update all your code for a wrapper code, see Xah Emacs Blog

trick to Append String in Loop efficiently and observe a design problem programing languages, how a programing language requires hack. from my understanding, it seems impossible for a programing language to avoid such problem.

for flight, some of the top interesting properties is can it: hover, glide, fly backward, agility, speed, lift power, enegy efficiency. For ground based locomotion, some are: stability, speed, agility, power, carrying capacity, efficiency, terrain, control complexity.

why are we interested in flight here? because, the various mechanisms of birds/insects, are interesting with respect to engineering. but note, walk/run is also quite interesting mathematically, in that the number of legs, and “gaits”, have diff properties and limits.

more generally, there are all considered locomotion. that is, how a animal propels. so what's the diff between “flight” and “walk/run”. The essence, is one is based on fluid dynamics, vs friction.

should we include sting-ray as flying? depends. one is air, one is water. In physics, they are both fluid dynamics. But due to density, the mechanism and flight property, is significantly different. If we include, then we have types such as: dolphin, shark, ray, even octopus et al.
