Softpanorama Switchboard

He who will not reason is a bigot;
he who cannot is a fool;
and he who dares not is a slave.
- Sir William Drummond

The main purpose of the site is to promote "slightly skeptical" approach to IT, to stimulate critical thinking about system administration and software development as professions. To increase resistance to media brainwashing. Skepticism is generally any questioning attitude towards knowledge, facts, or opinions/beliefs stated as facts, or doubt regarding claims that are taken for granted elsewhere.

We try to eschew the conventionally favored obfuscations about IT workplace and related propaganda (for example about "cloud computing" or IT outsourcing) and expose the theater of absurd which often both academic and, especially, corporate IT represents (sometimes in the form of humor; it's often the best medicine against conformism, stress, and overload.). It is important to be aware about dangers of the IT workplace such as psychopathic bosses (aka toxic managers). The latter have several varieties with micromanagers, bullies, narcissists and authoritarians as the most common. You also need be aware of a standard under neoliberalism corporate waterboarding procedure called performance reviews ;-). After all you are just a consumable resource.

Due to resources limitation this is a very limited and incomplete effort. Layout of the site Spartan with mostly plain vanilla HTML and design tries to avoid overcomplexity trap even if at some expense of readability. Some pages are long, some very long.

Not all pages are current: the site develops as a living tree and active area migrate with time depending on the current interest of the author. Many links are broken, but using Google one can find new location for probably 80% of them. The rest is gone: electrons have some weaknesses in comparison with paper as for long term storage of information :-).

Softpanorama is a very simple in layout, Spartan site. It does not use any Web 2.0 technologies. It's primary focus is self education and in this area content is the king. So based on limited resources we have, sophisticated layout was sacrificed. The site is one of the few "compiled' web sites where target pages are not generated on request, but are precompiled when a change in content arrives.

In 2012 "open source" is really old overused and abused concept and computer science education that once was flourishing, now is a neglected area in deep crisis. Very few people understand that computer science (CS) education is one important area were open source really shines: the academic value of open source software (OSS) cannot be overestimated ( "free/open for education" is one of the most important meanings of "free software".)

This site promotes exactly this usage of open source and view open source development as a special type of academic research (with the same pitfalls and limitations involved). Open source like love is a very complex subject and we reject romantic ideas inherent in both Stallmanism and Raymondism. For example, I see nothing wrong with using open source development as a career jumpstart, the stage on which talented programmers can demonstrate to themselves and the world the level of their talent before moving on to other, possibly closed source, projects. And vice versa, after such person works in corporate environment for several years, the frustration can reach level when some level of participation in related to work experience open source project might be a good safety valve, the best way to preserve sanity :-).
