When everything around you is so screwed up and you pile your hopes on one thing, looking forward to it. It takes you by surprise just to know that it did not go the way it was supposed to...
As a matter of fact is the highest point of frustration....

"Words" - not commonly used that I came across while reading papers

The social importance of immunology cannot be gainsaid.

TTL field IPv4
The TTL (Time To Live) field in the IPv4 header is not exactly the Hop Counter.
It is actually the maximum lifetime of an internet packet in the internet."
Extract from RFC791 - Internet Protocol
It is actually the maximum lifetime of an internet packet in the internet."
Extract from RFC791 - Internet Protocol
Time to Live: 8 bits
This field indicates the maximum time the datagram is allowed to
remain in the internet system. If this field contains the value
zero, then the datagram must be destroyed. This field is modified
in internet header processing. The time is measured in units of
seconds, but since every module that processes a datagram must
decrease the TTL by at least one even if it process the datagram in
less than a second, the TTL must be thought of only as an upper
bound on the time a datagram may exist. The intention is to cause
undeliverable datagrams to be discarded, and to bound the maximum
datagram lifetime.

Non US citizens looking for positions in the defense sector
Based on my conversations with the recruiters from companies in the defense sector
Security clearance is necessary for many job positions available in this sector. To attain a minimal clearance a person has to be at least a permanent resident of the US. Moreover you should be sponsored to get your security clearance.
Though most positions require permanent residency or citizenship, there are positions that are open to other candidates. Many a time, such positions would be related to support, human resource and other verticals that do not deal with sensitive data.
From an CS engineer point of view or for any discipline for that matter, to know more and grow in an organization, you need the flexibility to explore various options available to you and grab opportunities that would add to your credibility. Such positions require responsibilities. Your lack of security clearance or residency status would stand in your way to get to responsible positions, and indirectly your growth.
The words from the recruiter " Though we have positions open for non - US citizens, they would would be mostly support oriented. Your options for moving around is very limited because of your clearance status. You need to be a permanent resident to procure a security clearance and we will not sponsor you for that.
This has been the case for long. But with the number of open positions and the talent pool available to us, there might me a relaxation in the selection procedure. May be 10 years from now or even more "
- Donot get your hopes high. Donot lose it too.
Anyway, do look through the available positions and if you think the position suits you well and you can stick to it for some time, you should give it a shot.
My opinion is that it is not one of the best possible places to grow or to start your career.
If you are wondering as to what companies I am talking about, they are companies like Northrop Grumman, Lockheed Martin.. They do awesome stuff :)
