Linus Torvalds — The Facts You Didn’t Know

Welcome to Linux Screw! If you're new here, you may want to subscribe our RSS feed.

Linus TorvaldsSome of you may well be younger than Linux, some of you may have grown up with the OS, and some of you, more ancient ones, may well remember thinking that this stuff is going to ‘blow the bloody doors off’ as Michael Caine put it when you first encountered it. But how about Linus Torvald, the man who wrote the first kernel? Here we’re going to give you an insight into his life and personality.

He is Finnish but actually grew up speaking Swedish. This is because Linus is one of the “finlandssvensk” or “finlandssvenskar” community in Finland. These were Swedes who moved to Finland many hundreds of years ago when the country was part of the Swedish Empire and continue to speak Swedish.

It was on August 25th 1991 that Linus announced to the Usenet newsgroup “comp.os.minix.” that he was making a free OS, although he thought it wouldn’t be big or professional like Gnu. Well, who would have thought that Linux would turn the computing world on its head?

He hates phones, which he believes distracts him from more important things in life. This doesn’t mean he doesn’t own a phone, he just uses it for the GPS function when he’s driving.

Linus Torvald rarely gets to code any more. This is not because he’s spending all his time looking at his bill on www.o2.co.uk or crafting amazing images on photoshop, no, he’s replying to a huge email in-box and the few bits of code he does write are usually pasted in emails to questions explaining what to avoid.

I don’t know how much tea or coffee you drink, but Linus reckons he is a coffee addict and calculates that he and his wife have drunk an average of 4.7 double shots per day between 2002 and 2010 and that’s not including take-out coffees.

Despite this caffeine intake, he still manages to get a fairly serious nine hours sleep a night (he goes to bed at 10 and gets up at 7).

Perhaps this is because he likes drinking Guinness, that Irish stout from Dublin that contains a serious amount of iron and used to be taken as a health tonic in the British Isles before modern fads changed peoples’ opinions.

Prior to having laser surgery, Linus used to wear spectacles.

He is married and lives in Portland, Oregon with his wife Tove and their three daughters.

The Implementing Cisco IP Routing (CCNP Route 642-902). Materials for efficient preparation to the exam.

cisco logoA few days ago I have successfully passed 642-902 exam (CCNP ROUTE v6) and would like to share the list of materials I have been using to prepare to that exam. To get prepared I was using official Cisco Press training resourses, lab simulations and cheat sheets (before actually to go an take the exam). In this post I’d like to share this staff with you.

A few words about CCNP ROUTE 642-902 exam. This is the first one of three qualifying exams for CCNP, CCIP and CCDP. If you plan to become one of those certifications you must take 642-902 (the possibility to take the composite CCNP exam is also opened). Cisco ROUTE exam contains detailed information regarding implementing of EIGRP, BGP, OSPF dynamic routing protocols, redistribution between different protocols, filtering, summarization/aggregation and a lot of related stuff. You can read more at Cisco Learning Center.

Main Preparation Materials

Lab Simulations

I’ve been using the only available emulation software of this kind: dynamips. There are a lot of information available about it around the web. Meantime it is worth to say that Packet Tracer’s functionality is far not enough to complete labs coming with CCNP ROUTE so using of dynamips is mandatory. It is clear that every lab include more than three routers in it so you should be able to interconnect devices between each other using different kinds of connection e.g. Serial or FastEthernet. I used GNS3 for this purpose and it did its job perfectly.

Cisco CCNP ROUTE Cheet Sheets

Before actually to take an exam it makes sense to sum everything up in your mind so you should us cheat sheets for this purpose. I’ve been using Cisco cheat sheets which were prepared by Jeremy from www.packetlife.com, here are the direct links to them:

Good luck!
