Pablo Neruda – I Like For You To Be Still

I like for you to be still
It is as though you are absent
And you hear me from far away
And my voice does not touch you
It seems as though your eyes had flown away
And it seems that a kiss had sealed your mouth
As all things are filled with my soul
You emerge from the things
Filled with my soul
You are like my soul
A butterfly of dream
And you are like the word: Melancholy

I like for you to be still
And you seem far away
It sounds as though you are lamenting
A butterfly cooing like a dove
And you hear me from far away
And my voice does not reach you
Let me come to be still in your silence
And let me talk to you with your silence
That is bright as a lamp
Simple, as a ring
You are like the night
With its stillness and constellations
Your silence is that of a star
As remote and candid

I like for you to be still
It is as though you are absent
Distant and full of sorrow
So you would’ve died
One word then,
One smile is enough
And I’m happy;
Happy that it’s not true.

It’s been 18 years since I joined Volvo, a Swedish company. Working for them has proven to be an interesting experience. Any project here takes 2 years to be finalized, even if the idea is simple and brilliant. It’s a rule.

Said in another words:1. Sweden is about the size of San Pablo, a state in Brazil.2. Sweden has 2 million inhabitants.3. Stockholm, has 500,000 people.4. Volvo, Escania, Ericsson, Electrolux, Nokia are some of its renowned companies. Volvo supplies the NASA.

Nowadays, there’s a movement in Europe name Slow Food. This movement establishes that people should eat and drink slowly, with enough time to taste their food, spend time with the family, friends, without rushing. Slow Food is against its counterpart: the spirit of Fast Food and what it stands for as a lifestyle. Slow Food is the basis for a bigger movement called Slow Europe, as mentioned by Business Week.

This no-rush attitude doesn’t represent doing less or having a lower productivity. It means working and doing things with greater quality, productivity, perfection, with attention to detail and less stress. It means reestablishing family values, friends, free and leisure time. Taking the “now”, present and concrete, versus the “global”, undefined and anonymous. It means taking humans’ essential values, the simplicity of living.

In the movie, Scent of a Woman, there’s a scene where Al Pacino asks a girl to dance and she replies, “I can’t, my boyfriend will be here any minute now”. To which Al responds, “A life is lived in an instant”. Then they dance to a tango.

Congratulations for reading till the end of this message. There are many who will have stopped in the middle so as not to waste time in this globalized world.

"I’m a novelist. My work is human nature. Real life is all I know. Don’t ever  confuse the two, your life and your work. You will walk out of here this afternoon with only one thing that no one else has. There will be hundreds of people out there with your same degree: there will be thousands of people doing what you want to do for a living. But you will be the only person alive who has sole custody of your life. Your particular life. Your entire life. Not just your life at a desk, or your life on a bus, or in a car, or at the computer. Not just the life of your mind, but the life of your heart. Not just your bank accounts but also your soul. 

People don’t talk about the soul very much anymore. It’s so much easier to write a resume than to craft a spirit. But a resume is cold comfort on a winter’s night, or when you’re sad, or broke, or lonely, or when you’ve received your test results and they’re not so good.

Here is my resume: I am a good mother to three children. I have tried never to let my work stand in the way of being a good parent. I no longer consider myself the centre of the universe. I show up. I listen. I try to laugh. I am a good friend to my husband. I have tried to make marriage vows mean what they say. I am a good friend to my friends and they to me. Without them, there would be nothing to say to you today, because I would be a cardboard cut out. But I call them on the phone, and I meet them for lunch. I would be rotten, at best mediocre at my job if those other things were not true.

You cannot be really first rate at your work if your work is all you are. So here’s what I wanted to tell you today: Get a life. A real life, not a manic pursuit of the next promotion, the bigger pay cheque, the larger house. Do you think you’d care so very much about those things if you blew an aneurysm
one afternoon, or found a lump in your breast?

Get a life in which you notice the smell of salt water pushing itself on a breeze at the seaside, a life in which you stop and watch how a red-tailed hawk circles over the water, or the way a baby scowls with concentration when she tries to pick up a sweet with her thumb and first finger.

Get a life in which you are not alone. Find people you love, and who love you. And remember that love is not leisure, it is work. Pick up the phone. Send an email. Write a letter. Get a life in which you are generous. And realize that life is the best thing ever, and that you have no business taking it for granted. Care so deeply about its goodness that you want to spread it around. Take money you would have spent on beer and give it to charity. Work in a soup kitchen. Be a big brother or sister. All of you want to do well. But if you do not do good too, then doing well will never be enough.

It is so easy to waste our lives, our days, our hours, and our minutes. It is so easy to take for granted the colour of our kids’ eyes, the way the melody in a symphony rises and falls and disappears and rises again. It is so easy to exist instead of to live. I learned to live many years ago. I learned to love the journey, not the destination. I learned that it is not a dress rehearsal, and that today is the only guarantee you get. I learned to look at all the good in the world and try to give some of it back because I believed in it, completely and utterly. And I tried to do that, in part, by telling others what I had learned. By telling them this: Consider the lilies of the field. Look at the fuzz on a baby’s ear. Read in the back yard with the sun on your face. Learn to be happy. And think of life as a terminal illness, because if you do, you will live it with joy and passion as it ought to be lived".

I dont know whats the current situation in India, but I think the "geek-has-brilliant-idea-gets-funded-and-becomes-millionaire" story is not at all common here. But its pretty common in US and its really useful (and more importantly fun ) to learn from their experiences if you are looking at start-up’s. Anyway….A new term for me in that respect was the term Angel Investor.

Angel Investors (or simply Angels) are affluent individuals who provide capital for business start-ups, usually in exchange for an equity stake. Unlike venture capitalists, angels typically do not pool money in a professionally-managed fund. However, angel investors often organize themselves in angel networks or angel groups to share research and pool investment capital.

Intresting Idea and I also think it make a lot of sense for the startup since they can get support by puttling less at stake and while they are mature enough to more into talk to VC’s they would be in a much stronger position and also better educated in the tricks and trade from the master himself

A very interesting write up on one of them is available at the msnbc site.It seems to pretty similar to the dragon’s den show that I loved to watch while in UK, except that here the money involved is much less and also the stake they ask for in the company is also very low.

 In this respect,when can we see a Ycombinator in India, or does it exist already?

The big 4 in EDA are trying to be the first to the DFM market by buying out the smaller specialist companies in the DFM field.

Now it is Mentors Graphics turn

Mentor buys 45nm chip design tool firm

Mentor Graphics has acquired Sierra Design Automation a supplier of place and route semiconductor fabrication tools for 65nm and 45nm process nodes.

The reason behind the acquisition is the need to address the range of process technologies and new design for manufacture (DFM) methodologies which are expected to influence next generation chip designs.

Earlier it was Cadence

 Its fun watching a industry evolve  and be in it rather than read about something that happened before you were born

Really good statement from a person I am starting to admire, Rajeev Madhavan, CEO of magma….
What he says about the IP’s getting integrated with the EDA tools seems to be correct; I mean the way I see its virtually important for single-IP based startup’s to come up. To compete with the abundance of so called "infrastructure" IP pool that the big player’s have. See, what’s the point of a single IP company with expertise in DSP spending time/money developing buying infrastructure IP like IIC and SPI and trying to integrate it into their environment? I would always buy it from the tool vendor provided he gives me a plug-in solution to my environment and also to me at a competitive rate. I know with the technology purists there is some resentment to club IP vendors with EDA industry,but from what I have gathered, we are moving into a area where IP would make a substantial section of the EDA tool’s profit and it doesnt ake sense for me not to leverage on a earning oppertunity as long as it does not affect your work in your core competencies and may even fund more research in the Core business of EDA and talking of the crowd, wouldnt at least some of the people who buy the tools be also in a position to dictate the IP buying for their respective companies? Since I have not attended DAC I cant comment, but I feel probably yes….

Coming back to the heading of the post, in the shark eat fish world of EDA industry….this statement….so well sums it up

Me and my best buddy Zubin, who’s a fanatic RedShite supporter, have this habit of trying to find analogies with the football world ,actually the English premiership, and the everything else in life, and while trying to explain the EDA industry to him ( him being totally clueless as he’s from the ERP field), he came up with a interesting analogy
 The EDA companies investing in their own R&D is like the clubs investing in their academy, there is a remote chance of getting a Rooney or a Gerrad ( which would be a break through idea like Custom wire load models  ? ) but chances are less….mostly you end with a squad player like Tony Hibbert ( which in EDA terms would be some flow development/refinement, which would seamlessly integrate the different tools or flow reference model etc)  who is none the less very important for the success of the team (the tool) . And  some club like Wolves would come up with Joelen Lescott (in EDA terms some geek graduate from college would come with the next big Idea of, say,  DFM (design for manufacturability)), but the club wont achieve anything because he alone cant will them matches ( the DFM idea wont survive on its own) and would be brought by the big club ( would be brought by Cadance for example…integrated to their flow to make a world class product) and the club would win the Champions league ( successful chip tapeout perhaps ) ….
 To add my own parts to it
 Categories create companies (different clubs have different type of playing like arsenal and Manu for one touch football and Chelsea playing the direct approach and Everton with the work-rate based play) Features get acquired ( features are key players with key skills that are either acquired or developed in-house) but the company has to think properly to look at what to acquire, not only just how good the idea is but also how well it suits their category ( not look at just how good the player is but also that his skills are what the team needs or u will end up being Arjen Robben at Chelsea, a brilliant player WASTED)
 
anyway I have kept all the beautiful people in my dreams waiting today for too long……

Good night and Au revor Kochi

 http://www.electronicsweekly.com/blogs/intellectual-property/2007/05/new-business-models-for-ip.html

There are 3 fundamental business models that are in play today:
• License fee + Royalty. In this classic model practiced by leaders such as ARM, the customer pays an upfront fee for the rights to use the IP and then pays the IP owner a royalty based on the percentage of the value of the chip it’s used in.
• Subscription model. This is typically a royalty-free model practiced by leaders such as Synopsys that treats IP like an EDA tool. The customer can use the IP freely as long as they have the license needed to implement or simulate the IP. No more license, no more IP.
• Foundry subsidized model. This is typically practiced by the foundries who will provide certain IP to their customers as long as they use their fab. This effectively is a royalty-only model.

I think MindTree’s Bluetooth and UWB come under the first model and that seems the most profitable/logical to me. But  then again the other models would work well in their situations as well I guess. The article does talk about more evolved models that provide solutions, but I guess only time will tell about them

This following text is very useful for writing quick sed tasks….which can be then stacked on top of each other to implement complex functions.

FILE SPACING:

 # double space a file
 sed G

 # double space a file which already has blank lines in it. Output file
 # should contain no more than one blank line between lines of text.
 sed ‘/^$/d;G’

 # triple space a file
 sed ‘G;G’

 # undo double-spacing (assumes even-numbered lines are always blank)
 sed ‘n;d’

 # insert a blank line above every line which matches "regex"
 sed ‘/regex/{x;p;x;}’

 # insert a blank line below every line which matches "regex"
 sed ‘/regex/G’

 # insert a blank line above and below every line which matches "regex"
 sed ‘/regex/{x;p;x;G;}’

NUMBERING:

 # number each line of a file (simple left alignment). Using a tab (see
 # note on ‘\t’ at end of file) instead of space will preserve margins.
 sed = filename | sed ‘N;s/\n/\t/’

 # number each line of a file (number on left, right-aligned)
 sed = filename | sed ‘N; s/^/     /; s/ *\(.\{6,\}\)\n/\1  /’

 # number each line of file, but only print numbers if line is not blank
 sed ‘/./=’ filename | sed ‘/./N; s/\n/ /’

 # count lines (emulates "wc -l")
 sed -n ‘$=’

TEXT CONVERSION AND SUBSTITUTION:

 gsed ‘/./{H;d};x;y/\n/\v/’ file | sort | sed ‘1s/\v//;y/\v/\n/’

 # zip up each .TXT file individually, deleting the source file and
 # setting the name of each .ZIP file to the basename of the .TXT file
 # (under DOS: the "dir /b" switch returns bare filenames in all caps).
 echo @echo off >zipup.bat
 dir /b *.txt | sed "s/^\(.*\)\.TXT/pkzip -mo \1 \1.TXT/" >>zipup.bat

TYPICAL USE:

Sed takes one or more editing commands and applies all of
them, in sequence, to each line of input. After all the commands have
been applied to the first input line, that line is output and a second
input line is taken for processing, and the cycle repeats. The
preceding examples assume that input comes from the standard input
device (i.e, the console, normally this will be piped input). One or
more filenames can be appended to the command line if the input does
not come from stdin. Output is sent to stdout (the screen). Thus:

 cat filename | sed ‘10q’        # uses piped input
 sed ‘10q’ filename              # same effect, avoids a useless "cat"
 sed ‘10q’ filename > newfile    # redirects output to disk

For additional syntax instructions, including the way to apply editing
commands from a disk file instead of the command line, consult "sed &
awk, 2nd Edition," by Dale Dougherty and Arnold Robbins (O’Reilly,
1997; http://www.ora.com), "UNIX Text Processing," by Dale Dougherty
and Tim O’Reilly (Hayden Books, 1987) or the tutorials by Mike Arst
distributed in U-SEDIT2.ZIP (many sites). To fully exploit the power
of sed, one must understand "regular expressions." For this, see
"Mastering Regular Expressions" by Jeffrey Friedl (O’Reilly, 1997).
The manual ("man") pages on Unix systems may be helpful (try "man
sed", "man regexp", or the subsection on regular expressions in "man
ed"), but man pages are notoriously difficult. They are not written to
teach sed use or regexps to first-time users, but as a reference text
for those already acquainted with these tools.

QUOTING SYNTAX:

The preceding examples use single quotes (’…’)
instead of double quotes ("…") to enclose editing commands, since
sed is typically used on a Unix platform. Single quotes prevent the
Unix shell from intrepreting the dollar sign ($) and backquotes
(`…`), which are expanded by the shell if they are enclosed in
double quotes. Users of the "csh" shell and derivatives will also need
to quote the exclamation mark (!) with the backslash (i.e., \!) to
properly run the examples listed above, even within single quotes.
Versions of sed written for DOS invariably require double quotes
("…") instead of single quotes to enclose editing commands.

USE OF ‘\t’ IN SED SCRIPTS:

For clarity in documentation, we have used
the expression ‘\t’ to indicate a tab character (0×09) in the scripts.
However, most versions of sed do not recognize the ‘\t’ abbreviation,
so when typing these scripts from the command line, you should press
the TAB key instead. ‘\t’ is supported as a regular expression
metacharacter in awk, perl, and HHsed, sedmod, and GNU sed v3.02.80.

VERSIONS OF SED:

Versions of sed do differ, and some slight syntax
variation is to be expected. In particular, most do not support the
use of labels (:name) or branch instructions (b,t) within editing
commands, except at the end of those commands. We have used the syntax
which will be portable to most users of sed, even though the popular
GNU versions of sed allow a more succinct syntax. When the reader sees
a fairly long command such as this:

   sed -e ‘/AAA/b’ -e ‘/BBB/b’ -e ‘/CCC/b’ -e d

it is heartening to know that GNU sed will let you reduce it to:

   sed ‘/AAA/b;/BBB/b;/CCC/b;d’      # or even
   sed ‘/AAA\|BBB\|CCC/b;d’

In addition, remember that while many versions of sed accept a command
like "/one/ s/RE1/RE2/", some do NOT allow "/one/! s/RE1/RE2/", which
contains space before the ’s’. Omit the space when typing the command.

OPTIMIZING FOR SPEED:

If execution speed needs to be increased (due to
large input files or slow processors or hard disks), substitution will
be executed more quickly if the "find" expression is specified before
giving the "s/…/…/" instruction. Thus:

   sed ’s/foo/bar/g’ filename         # standard replace command
   sed ‘/foo/ s/foo/bar/g’ filename   # executes more quickly
   sed ‘/foo/ s//bar/g’ filename      # shorthand sed syntax

On line selection or deletion in which you only need to output lines
from the first part of the file, a "quit" command (q) in the script
will drastically reduce processing time for large files. Thus:

   sed -n ‘45,50p’ filename           # print line nos. 45-50 of a file
   sed -n ‘51q;45,50p’ filename       # same, but executes much faster

Along with the Cool name the site proved a great free service thats not great just cuz its free ….

Will write about how it goes it time I guess….
