I disagree that using shell CGI scripts should be considered security hole any more than using CGI scripts written in any other language, but if you want other examples of exploiting this bug you can do it via malicious DHCP responses processed by dhcpclient or by env. variables passed when loging in via SSH.

Your CGI script doesn't need to do anything at all. The rogue code injected into the env. variables is parsed and executed by bash when it sets-up the environment for your script.

It should be marked offtopic, same as my and your post (too bad i don't have any mod points)

This is not true. Any sane methodology used to compare wages excludes over time hours (which are paid separately, at least in EU). See for example the Methodology paragraph on this site, which describes how they do it in UK.

I think you missunderstand the meaning of the word 'accept'. From merriam-webster dictionary:

I think that it is clear that to 'accept' something as payment you don't need to hold it afterwars. You are free to convert it to something else or use it in any other way you see fit. To give you some example, few people would argue that steam, google play or blizzard online store is not accepting euros because they convert it to dollars after the purchase.

Yes, we do accept payments in foreign currency if we are running international bussiness.

Accepting bitcoins doesn't mean that you stop taking other forms of payments so this is no valid downside for merchant who start to accept bitcoins in addition to existing forms of payments.

For example to stream windows only games from my basement server to lightweight linux-based HTPC in my living room.

Cloud services which use client-side encryption can store your private data securely. Mega.co.nz for example offers 50GB of storage space for free and they have support for linux, windows, mac nad android.

Reasonable limit would be 10 years initialy + 10 year extension if the creator wishes so. The best solution would be to abolish copyright completely and provide money for creators in some other way without artificial limits on content distribution. Current copyright doesn't help creators, it is tailored for the needs of distributors because it is a mean to control distribution. Creators don't need distribution limits (it is actualy bad for them as it lowers their exposure to potential audience), they need money.

Patent law is more complex and i think that the current model is not so bad, the problem is the patent office which is not competent in patent aplication review and juridical system which makes invalidation of bogus patents expensive and lengthy and which enables patent trolls to thrive.

Einsteins theory doesn't use gravity at all. It works with mass and energy which cause curved spacetime which then causes gravitational lensing. The dark matter is predicted by this effect because we can't detect enough normal matter to justify the level of light-bending we can observe. Dark matter is also predicted by several other observable phenomena like the speed galaxies rotate around each other or cosmic microwave background.

Please try to send the message and let us know how it worked. I think that you'll discover that your "illusion of freedom" is very far from actual reality.

What is so great about it? Isn't it just another government-issued currency?

Jitsi looks realy nice. I want to try it myself when i need videoconferencing later this year. There is also Jitsi videobridge which you can deploy on your server and use Jitsi meet web client to connect to it. Or you can use 3rd party maintained instalation of videobridge available at https://meet.jit.si/

If you understand networks and are not afraid to setup your own router from scratch, i recommend mikrotik router boards. For home use, i'd use something like RB951G-2HnD
