Lol. A list of programing cults. But one of them, is truly the best. Cowboy coding. A proper name for that is craftsmanship. And there's one truth among the list, but isn't listed. That is: mathematics, knowledge and discipline

This is when sigil comes in. And when, literate programing vs symbolic logic. Or, literate programing vs formal logic.

As for camelCase vs snake_case, snake is technically better. It has isomorphism with words, where space=lowline. But camelCase is more natural. Lowline char is just specifically invented for computer, but camelCase is used outside computing, hundreds years earlier.

Will PureScript be Popular?

Seems a great lang but prob little future. PureScript probably will have fewer users than the already niche haskell, clojure, clojurescript. Also, too many langs today: Elm, haxe, dart, typescript, reason ml, buckscript, julia, nim, crystal, “all” compile to js. Growing.

MacOS 10.14 Catalina Upgrade Notes

just upgraded my MacMini (late 2014) from high sierra to Catalina. (skipping majove) the upgrade is smooth. Takes about 50 min. so far, no problem, except Brave browser crashing.

see my Mac Mini Late 2014 Spec

MacOS now changes your disk format from HFS Plus to the new APFS Apple File System . APFS is new in 2017. This happened since macOS version version 10.14 (aka macOS Mojave) released in 2018, or MacOS 10.13 (High Sierra) released in 2017-09.

macOS APFS 2020-02-17 8m25k
macOS APFS 2020-02-17

Also, the macOS has its own partition, read only.

uBlockOrigin is lost on the Mac. https://github.com/el1t/uBlock-Safari/issues/158 . It'll soon be gone on Google Chrome too. while Firefox is donating to antifa, n sell your data. uBlock adBlock etc were open source now malware. (the story of open source) Faak the open source fsf skums that got us this situation.

Default shell is now zsh. Apple stopped using bash because its license is GPLv3, which is control freak license from FSF. (for the same reason, the emacs bundled with Mac is 10 years old version) So, Apple simply switched to zsh. Which is actually a better shell.

Apple (and Microsoft too) is increasingly doing software by ID only. On one hand, it creates security, less malware, prevent theft. But, it also means, massive central control.

Comes a day, no software can run on a machine unless Apple or Microsoft approved it. This may or may not happen, in the future.

Apple removed commands ftp and telnet in macOS 10.13, year 2017

so Apple now has MacOS, iOS and iPadOS

so Apple now has MacOS, iOS, and iPadOS. i think Microsoft's better, just 1 Microsoft Windows OS. The great thing is that, on Windows, you have touch screen support, on any device. Also, you need to understand just 1 OS. For example, macOS and iOS is rather very different. All the dir structures are diff.

minor corrections. thanks to “and hi”

old linux rant, on monitor color calibration. written in 2013-02-12

linux, desktop. So, this poor sob got a new monitor. The monitor shines in vivid colors, like, red is more red, and skins is a glowing pink. So, this poor sob wanna calibrate his monitor. O, i'm on the great linux desktop. After some web search, i forgot such tools are buildin in Mac and Windows, as the search results kept reminding me.

After a while, stack-overflow-ubuntu 'n' all, i found this thing called gnome-color-manager. Great, since i'm expert unix master so i went apt-get and quickly installed it. (searching for the right package name and all i won't bog you down with). But how do i run the thing? xfce control panel's doing a no show. My nice bash name-completion system showed gcm-view, gcm-calibrate, etc, but they don't work. Man pages are on the quite side when you need them to talk. More Gooogle skynet, i'm glad the right answer is gcm-prefs --verbose to launch the nice GUI we are un-dying for. But gcm-prefs don't exist here.

Thank you linux, for, i've decided not to do anything about this. You are my time saver today! If i were on a Mac or Windows, i'd doubtless wasted hours for useless appearance things.

tip of the day

ad blocker collateral damage euphemism

apparently, adblock or ublockorigin will block a image talking about google ad ban.

goto

Google AdSense Ban on Ancient Asian Goddess Sculpture Page

and the screenshots are not shown. Turn off ad blocker, it shows.

The cause is the image file name. If rename so it doesn't contain “google adsense”, then it works.

faak google and open source, fsf, fanatics.

well, typically, the open source fsf fanatics, they think ad blocking is way to go. and that is the problem i have here. military euphemism: collateral damage. talking about google ban gets filtered out.

my claim: it is the open source, fsf, fanatics, these idiots, that got us into this condition. Far worse than 20 years ago. not to mention cloud.

The piping syntax problem is solved by Mathematica 30 years ago

The piping syntax problem is solved by Mathematica 30 years ago 😤 The thing about piping to 2nd 3rd etc args is no good. When pipe, best to let it juts have 1 arg. but, for the need to pipe to 2nd arg, you solve it by a generic function notation that has slots for 2nd etc args. for example, here's a function of x+y, like this (#1+#2 &) , parenthesis optional.

screenshot 2020-01-03 sfvpd
Math: Density Plots of Trig Expressions

for example, to pipe to 2nd arg, we have have this x | f(3,#)

to pipe to 3rd arg, this x | f(a,b,#)
