Backend of Meta Threads is built with Python 3.10

flashang — Wed, 12 Jul 2023 17:13:13 +0800

Well, company wants the new / update system to be up 'yesterday'.
they tell you today, this is very urgent.

So, faster deployment is more important,
performance can be improved by more powerful servers,
software performance tuning may be only when the team have nothing to do (which could bring to axe...).

Intel proposes dropping 16 and 32-bit support

flashang — Sat, 03 Jun 2023 10:41:33 +0800

Time to drop the old tech and move on ?

Let the old devices "as-it" (no more develop and update)
And only new devices will have new update ?
* You may have issue to buy / repair old devices.

Old tech may become legend skills but have no place to use.

The lyrics just came out :
They stab it with their steely knives
But they just can't kill the beast ...

My 20 Year Career is Technical Debt or Deprecated

flashang — Fri, 19 May 2023 10:48:13 +0800

how many of 'new technology' we learnt before,

- now throw it away ?
- avoid to use it with new projects ?
- try to find a replacement ?
- doing migration to another 'new technology' ?

IMHO, we should solid our basic skills and knowledge,
and always available to change or choose some proper tools.

The Great Gaslighting of the JavaScript Era

flashang — Wed, 22 Mar 2023 12:25:54 +0800

There are a lot of article explain why we should use framework, we don't repeat here.

How many people are still available to make a professional level website without framework,
after they used to work with framework for years ?

By the way, do we really need to build everything with js (frontend + backend) ?

Using library is "easy", but how many people choose the right library wisely ?
Sometime, we may just want to have a vehicle which could run on the road, floating on the water, and fly across the river...
But we might just "want" the features, not use it.

How many % does people understand about their own code ?

using calculator :
3 * 3 = 9
9 * 9 = 81
81 * 81 = 6561

P/S: if remove printf( "%d", c );
compiler will shorten to
movs r0, #0

because the variable c was not been used...

IMHO, programming is learn logical thinking, calculation and flow control.

For other features, beginner may call the API (black box),
unless they want to understand how it work, or create themselves.

Tools are keeping improve, learn programming become easier.

Do you agree developer corrupts their open source project ?
Or, if you have some open source project, will you delete it and switch to commercial product ?

Sometime we might feel "unfair" as people using our hard work to earn money without any compensate or encouragement with a single cents.

Use of low-code & no-code technologies to triple by 2025: Report

QUOTE

Low-code and no-code have already been hailed as the second digital transformation.
No-code tools offer companies the fastest and cheapest way to scale their digital transformation across their entire business.
The low-code/no-code space also see their platforms as paving the way to a future where there simply aren't enough professional developers to handle the coming workloads.

Here's what the recent Gartner report says about the rise of low-code & no-code:
1. The use of low-code and no-code technologies will nearly triple by 2025.

2. By 2025, 70% of new applications developed by organizations will use low-code or no-code technologies, up from less than 25% in 2020.

3. Application development will shift to application assembly and integration. The applications will be assembled and composed by the teams that use them.

4. The technological and organizational silos of application development, automation, integration and governance will become obsolete

The rise and rise of low-code and no-code
The rise of low-code and no-code means also means extending the lives for existing applications. Experts say providing more efficient access to existing back-end applications will effectively extend the useful life of existing applications. Industries that aren't tech-heavy that will benefit the most from low-code/no-code.

Will you / your company use low-code / no-code to develop application ?
