How To Read The Signal Queue Of A Process??

Hi,

I am not completely new to linux.

My problem is the following:

The signal queue of my process gets filled with time.

With /proc/PID/status --> SigQ 6032/6032 i can see that the queue is full!

And my software is waiting on signals to process data. So I want to know wich signal filled my queue and I am interested to see the attached data of the signal --> sival_int or sival_ptr, I use sigwaitinfo() to read the data.

Getting Variable Integer Values From Grep

I want to write a Python script. In order to write it I need to figure out how to access the values associated with my signal level and bit rate.

If I use the following command

Code:
iwconfig | grep 'Signal level'

I get:

eth0 no wireless extensions.

lo no wireless extensions.

Link Quality=70/70 Signal level= -38 dBm


Obviously, I don't want Signal level. I want whatever it happens to be. In this case, it happens to be -38. Ditto Bit Rate...How do I grab -38 from the command line?

Netbook Linux Distro For Software Development

Hey guys, I am trying to find the best lightweight OS for my asus eee pc seashell series which I mainly use for programming; nothing heavy of any sort, just simple programs written in c++ and java for projects and stuff, I have my main pc for android studio and whatnot.

I'm currently using windows 7 ultimate 32-bit and it gets quite slow when I'm running netbeans + oracle sql and a couple of documents and web browsers etc.

Specs:
•Intel Atom N570 Dual core
•Intel GMA 3150
•2GB RAM

I have used Ubuntu 2 years ago for about a year, other than that I don't know anything about Linux distros. I have researched a few distros yet still skeptical about satisfying my needs especially the programming part.
Thanks in advance.

Navigation On KDE

I feel very stupid, 20 years ago I was a Unix 5 system admin at a Xerox plant using Sun systems and then Database admin at American Airline for Dec and HP versions of Unix. I have just brought up PCLinuxOS running from the DVD on a laptop and I could not even figure out how to shut down the system without tuning off the power. Any ideas of a good guide?

Modem

Can you tell me the name and model number of a modem that is suitable for Unix? Input ADSL2+ or ADSL2+ AND wINDOWS etc. Output Ethernet/Usb etc.The service provider is "BELONG" who will not support Linux software but says that he provides it and will test the modem for Unix. Iam at Miller Liverpool Sydney.

I Want To Dual Boot OSX And Linux & Make Better Use Of My 4g LTE V Data Plan.

Hello all, I currently have a very unreliable connection to the internet. I have a IPhone six that I was grandfather in on that has unlimited data and the personal hotspot feature on. I have bought many different modems, adapters..that is why I kept seeing this link pop up, (I was going to try and and even clone a ahhh "sheep" later). That is how desperate I am. I have rooms full of old hotspot devices. hardware, cords, routers, old phones, antennas, etc). I am currently just using wifi-over-wan on a CP-MBR95. As I am sure you all know this gives me barely enough bandwidth to download a Game of Thrones episode, and the signal fluctuates continually. In fact this is the second attempt at posting here because I lost the signal, and had to start over just as I had almost finished the last one, so I shall wrap it up. I would like any suggestions on what Linux version I should put on the awesome new hardware I received yesterday, and any suggestions on a bootloader would be great too. I am currently using Yosimite, but occasionally I need to play Skyrim or something so my head doesn't explode, or I wear out the reset button.

[B]Primarily[B], I need to first make sure I am at least getting enough bandwidth to justify my $180 a month Verizon bill (plus all the hardware I buy that never fits or works as expected, and ideally want be able to set up a VPN and share my data with friends. family, and community. I usually am quite impulsive, obsessive, and I do not often ask for help from others. That is most likely what has impeded my progress thus far. That and the fact the web can be loaded with poor information. I do not have any programming skills, but I have a strong imagination, and a willingness to learn. I also am devoted to aid the next curious soul who has the same fascination with getting in way over his head, and keeping at it until he at least knows more about something than he did if we spent his days with his head in the sand as sadly many of us do here in the US, especially the parts I'm from.

Thank you for suffering through that novice novella,
I look forward to learning what I can from you all.

Respectfully,
RaVen162

P.S. - I'm not sure how things work around here but if anyone has any suggestions at all, or have someway I can contribute, please don't hesitate to contact me. I got very close to losing my unlimited plan yesterday for upgrading to a 4g LTE phone on another line and putting the sim in the only plan with unlimited data. (if you ask questions like, "isn't that a violation of our contract by denying me the services I have paid for at an inflated cost for 8 years now." They usally say something like I'm not sure Sir. I'm not a lawyer..."OK can you put me in touch with him when he gets back from his deposition over at Tracfone"?.. got a call back 5 min later and he had no problems with what I did. By the way, just a heads up. I may me a smartass from time to time, but I am rarely one without the other. I apologize in advance for breaking any rules. Hopefully you guys will let me hang around for a bit. I really want to learn any OS I can, especially opensource ones. Thanks Again!
