LinSys Software was a software services company specializing in embedded systems, mobile applications, storage/networking, and Linux kernel development. This archive preserves the company’s technical documentation — most notably KGDB, the open-source Linux Kernel Source Level Debugger maintained by LinSys engineers from 2004 to 2011. KGDB was widely cited by Kernel.org, RedHat, Debian, Fedora, IBM developerWorks, O’Reilly, and major academic institutions.

Modern context

The Linux kernel debugger landscape has evolved significantly since the original KGDB era. Modern alternatives include eBPF/bpftrace for live tracing, ftrace for function-level tracing, kprobes for dynamic instrumentation, and GDB on QEMU for virtual machine kernel debugging. The conceptual framework KGDB pioneered — kernel-level source-level debugging via remote GDB stubs — remains central to all of these approaches.

Starting Meego …. 

Nokia and Intel have joined hands to create Meego – and this is their answer to Apple and Google (Android). So, the race for the best OS, that caters not just to smart phones, but also to netbook/netpad type of gadgets has begun. Different people are placing their bet on different technologies.
Being a Services company in System Technologies – we are really technology agnostic and like to take it “as it is”. To the intrusive, inquisitive team, Meego was (rather is) a new tool (toy) and we started exploring.

Our tryst with netpad was few months ago – when iPad and the Joojoo were creating waves, and possibly created space for netpad (or crunchpad or ideapad or ..), which never existed. We worked on one of the netpads to fix some of problems and enhance performance. No novice to System software we took deep dive into what OS should have to be ideal to netpad.

This is how our interest began … and we dived (prematurely) into the Meego World (One of the questions we still have is how did Meego get its name? Different combinations of parents – Moblin and Maemo sound funny).

Summarizing the first “mee on the go” of download and installation here.

MeeGo had only the developer preview on March 31 and we downloaded the “preview” image from the official website (www.meego.com). We were given two options – either to do chroot into the image file or transfer the image onto the hard-disk using dd command in Linux. We chose second option (We thought it would be easier and quicker and we were anxious to get started). We used a regular PC (Intel, dual core with 2GB RAM).

Soon – we realized that there was no graphical user interface. This, in our opinion – was the first hurdle to netpads. So we decided to get something up and running. Meego is still under development and not friendly to install packages. But we got Yum and installed all the X-server and xfce related packages. Firing the startx command we got the GUI up. It was obviously something very basic. The task to build complete UI for a netpad looks daunting at this stage, from this present basic stage.

Yes – Intel and Nokia is working to get up more and more. Do we wait for the official developers to build something and give. Or do we take up the task to ourselves. To the technologist – the challenge has only one way. Attack.

So here we started to get a UI for netpad – working in parallel the progressing Meego releases. 🙂
