I m notr complaining about the hardware. Or about the browser as an 
operating system The language - or at least the web APIS written in it, 
are utter shite.

Grace Hopper developed COBOL to make computers accessible to people who 
were not natural hardware boys. They were business analysts. Not coders.
Ever since, 'computer scientists', who are only one step above 
ArtStudents™ when it comes to being wankers of the first order, have 
been making up new languages that are so arcane that they simply 
*prevent* ordinary people trying to use a computer from solving a problem.

How many stock control systems are written in Prolog or Lisp?

After about three weeks, one browser  - and one only -  now works for me 
to start developing the code I wanted to develop.

That three weeks has been spent struggling with lack of documentation, 
examples that simply did not work that were copied one from another 
presumably without checking and layers of obfuscation created by what is 
simply fashion - making everything an object or a method, - that is 
arguably inappropriate for the task in hand. In short I am fighting the 
language - its is not helping me program, it is hindering me from 
programming.
It is just that in the applications I am building its marginally less 
worse than fighting that utter cunt Poettering and PulseAudio™, the 
project he abandoned half finished to wreck everyone's linux by 
inventing something no one wanted or needed - systemd.

"servers will boot faster with systemd"

The last thing I give a flying fuck about in a server is how fast it 
boots,. The aim or a server is to stay up for ten years at a time, and 
if I want it to boot fastger I'll put the OS on an SSD.


I'm too old to spend thousands of pounds on a course that would 
familiarize me with the exact syntax of 'constructors' and 'processors' 
or why you need to create and link 5 'objects' just to intercept an 
audio path, or why this must needs be done in background by an 
asynchronous task...and each one is quirky and requires different syntax 
depending on which browser one is using


JavǎScript, to misquote Tom Lehrer, is like a sewer. What you get out of 
it depends on what you put into it. It bears the stamp of CompSci all 
over it,. Designed to create a privileged class of gurus who understand 
the language, not competent journeyman programmers who can use it  to 
actually get a real world job done.

Bjarn Stroustrup admitted that half the point of C++ was to create more 
jobs for programmers....

Browsers, the DOM and JavaScript have been thrown together in a rush, 
and its is the exact opposite of - say  - php, which one guy designed to 
do a specific job, which it does pretty well - or did till it went 
object oriented.

Programmers today who have been On Courses and Passed Exams in stuff 
never stop to ask the question that some of us who grew up before 
computers existed, cant help but ask 'Is this actually better?'

Never mind a database, how many computerised systems that cost a fortune 
and dont work are better than say the old stock control system, where 
each part had the stock level on a card in a card index, and when the 
stock level got low you made a note on another card  of the part reorder 
level and put it in the pile of 'order some more'

And how much easer that is than catch( 
company.location[A].stockRoom.part[partno]=partsIssued.update.is 
negative)=>company.location.purchasing.part[partno]+=company.location.purchasing.part[partno].reorderLevel.
??

And even that is too esy. Let's construct a 'part deficit object'  that 
'extends class "profit"' and put it in the middle., just to show how 
fucking clever we are...and ensure that no one else will ever be able to 
maintain the code we wrote

A lie can travel halfway around the world while the truth is putting on 
its shoes.
