Is it possible to share computer screen with someone else over internet ?
I have attended few sessions of IBM where the presenter has shared his computer screen with the participants !
How should i go about to include this feature in my project. Any open-source API available to do the same ?
There are a lot of options when it comes to screen sharing. Wikipedia has a nice table comparing lots of remote desktop software.
One that looks fairly promising is FreeRDP. The source is on github and it seems to be pretty active project.
If you want to learn more, you can search for info about the Remote Desktop Protocol (RDP) which is what is being implemented in many of these programs.
If you are looking for something more web-specific (like Chrome's remote desktop), check out WebRTC. It is what the Chrome team is using to accomplish their screen sharing.
If you don't mind being limited to Chrome:
Chromoting (Chrome Remote Desktop) - Chromoting API
Google Hangouts - Hangout API
Skype also has a fantastic function for sharing screens. It allows an entire screen during a phone call for free. Makes working with someone on a project incredibly easy.
Go with TeamViewer, you can share your Computer Screen.
Else Go with Skype, share screen, Video calls etc etc.
I Personally like http://join.me
Its fast, small and easy to use.
Will hardly take few seconds to set-up!

Can you give me some good learning sources for UWP App development?
Currently I use the "Windows 10 development for absolute beginners" series on channel9. But it's not going in the depth.
I'd like to learn more about the anatomy of UWP apps and also some more advanced topics.
I recommend looking at MVA courses on the topics and level you need.
This one is a very comprehensive course. You can pick the modules of your interest - just note that it was updated in Aug 2015 and some things might have changed in the meantime. There are plenty of other resources that you can look at after that.
Please check below sources:
First one is official UWP guideline how to create apps. You can find here many different descriptions how to implement design of your app. Below you can download it as a PDF file:
http://go.microsoft.com/fwlink/p/?LinkId=626098
Second source can be official MSDN website with samples and descriptions related to Universal Windows 10 Apps:
https://developer.microsoft.com/en-us/windows/design
If you would like to create first simple Universal Windows 10 App I also recommend my blog where you can find many different articles connected with UWP:
https://mobileprogrammerblog.wordpress.com/2015/08/23/first-windows-10-universal-application-jump-start/
Hope this will help you.
Also check Windows-universal-samples from github. You can find code samples for everything you want to do with the platform straight from Microsoft.

I'd like a system where I can manage my LAMP server. It is a real server, so it isnt a VPS. But apart from everyone else online, I dont want to sell space on it. I just want to manage it for my own purpose.
So I can change settings on the fly without accessing the Shell.
I would of course like it to be an active, either open source or free software.
Web UI is also a requirement.
As any configuration tool on various web hotels, with possibility to configure only for one mashine, and no virtual spaces or such.
Would be great, as after tons of googling I came to the conclusion that there are tons of systems and they all are too advanced or just look aweful and seem to complex.
My goals.
Manage domains,
Manage emails for domains,
Manage Apache (possibly vhosts and such)
Manage MySQL (could use phpmyadmin)
Manage logs and similar
Manage SVN (if possible)
Manage FTP
And such features, not too advanced stuff.
Much appriciated if you know any good systems of such caliber. Thanks.
webmin (http://www.webmin.com/) might be what you're looking for.
Another could be http://isp-control.net/
And: http://www.syscp.org/
And again: http://www.ispconfig.org/

I'm looking to set up a small site for a friend that has some widgets they want to sell online. I don't think I will have much time for maintenance once it goes live (for that matter, I don't expect I'll have much time for initial setup and configuration), and I am looking for something that is dead-simple for a non-technical user to maintain (financial/payment info, add/remove/change products).
The second most important part would be good integration with a payment provider. I'm not too fussy what language it's in if it meets my other criteria (if I don't know the language I will learn enough to get the site running).
Also important is that I'd prefer to stick to open-source products, mostly because I don't think this project will have much of a budget for high-end commercial products (at least not until it makes some sales).
The last time I did this sort of stuff we were building custom sites from scratch for clients with very specific needs. I do not have recent experience with the current generation of blogging tools (Wordpress, Joomla, etc...) and I don't really know which off-the-shelf combo of platforms and plugins are best to get something up and running in as little time as possible.
Hosting your own online store is a full-time occupation, no different from running your own brick-and-mortar store. Anything that accepts online payments will be targeted by criminals for online fraud.
If your business is selling widgets and not running online stores, I strongly, strongly suggest using a hosted service with its own web integration and payment handling. I know people who have used both Weebly and Etsy and who are happy with them.

Can anyone recommend a good (preferably free) application or service to monitor the uptime of a server? And possibly send out an alert by email or sms when it goes down? Statistics are not really needed, it's just about knowing when a server goes down.
It depends how "sophisticated" tool you'd like to have (and install of course). You can use simple cron script on another server, or software designed for server monitoring. I've got experience and I can recommend you Zabbix or Nagios, but you can choose another one.
Try this
GAEAPIMonitor
http://www.honcheng.com/2010/12/GAEAPIMonitor---Open-source-API-monitoring-tool-on-Google-AppEngine
It is open source, written in python for AppEngine, so you can just run it on your own AppEngine account. Alerts you with a Twitter DMs when server is down, content has changed or has not changed, if an API is returning an invalid JSON if it is supposed to return JSON.
These are a few monitoring tools that you can try out
Free solutions
System commands: Nothing beats default commands like top, vmstat, iostat, netstat etc when it comes to knowing the health of a system
SeaLion: It is a cloudbased monitoring solution. What it does is basically execute all default system profiling commands (like top, vmstat etc) and present it in a very intuitive timeline format. It installation procedure is one of the easiest I have come across
Nagios: Though very complicate to use and configure, it is very
robust and most deployed solution available
Cacti
Zabbix
Paid solutions
New Relic
Server density
Copper Egg

I wish to know from SO security experts and hackers what kind of tools would they use to find a security hole in Chrome's armor? And using what programming and testing techniques?
I'm particularly interested in Open Source tools running on Linux.
Google announced on the Chrome Web Browser blog that they will pay 500$US for each security bug found. They plan to offer 1337$ for major bugs.
Thanks and happy bounty hunting!
just my opinion,
If you are not experienced in software you have better to exploit your skills doing some normal application/web app development then trying to get money from Google. After all two days of a freelance developer is about 500$.
Finding exploit is a difficult task and require really an huge knowledge of how computers works. There is many tecnics to discover exploits but almost none of them are automatic. If it was just using a tool Google would have done it themselves.
after for some basic tool you can try fuzzing tool but not really sure how it would behave with a browser.
Couple of points
Read up about fuzzing
Read up about Assembly language
Obtain a fuzzer
Obtain a reverse engineering program / Debugger (OllyDB, IDA Pro)
Sorry I can't be more help, but I don't do a lot of fuzzing myself. But the points above should help you find overflows and whatnot in Chrome, if there are any.
Finding exploits like this can be very tricky. I can only imagine the testing Google would give their apps before releasing them, but good luck ;-D
