Linkedin history 2006 - 2008
For a year, number of Linkedin users is going exponential vs time. When I look at number of connections vs network ratio (for myself), it can be seen that people are more and more connected with each other.I am not inviting any more people as I reached the number of people I am allowed to invite. The growth seen in the green curve (numbers of 1st level connections) is purely passive.
I have received 12 invitations per day for the last year. I am not advertizing my email anymore in my profile as it is now "strictly" forbidden, I mainly receive invitaions from LIONS and toplinked users. By the way, I did not see any diminution in the number of received invitations when removing my email from my profile.

Logitech Illuminated Keyboard
I am proud that my team delivered firmware for the new Logitech illuminated keyboard.
I especially appreciate working with this keyboard because it is illuminated. This is useful when you surf on the web or watch a video in the evening and you do not want to be disturbed by anything else than the computer screen.Something positive is also the fact that you choose the illumination level, as opposed to some automatic ambiant light system which choose the level for you.
This development was a challenge for our swiss team, as we are more specialized in developing wireless keyboards. We had to use a new chip that we had little experience with. The biggest obstacles we encountered was not because of the chip itself, but because of the compiler badly translating the C language to assembly code: "what you write, is not what you get". And this triggered some bugs that we had great difficulties to track and correct.

LotusNotes vs Sharepoint
One of my job related questions is: "How long am I going to (suffer from?) using LotusNotes everyday?". Here are some various feedbacks that I got when asking:
"SharePoint is fast becoming the next IBM Lotus Notes — and not in a good way. For years people implemented Lotus Notes databases like crazy, seeing them as the best way to store and share information. Now you hear more about moving all the content and data into SharePoint. But what’s the point if you are just going from one messy datastore into another?"
Move Over Lotus Notes, SharePoint is Filling Yer ShoesHas anyone migrated from Sharepoint to LotusNotes?
What is the future of Lotus Notes?
My (temporary) conclusion is if you're using LotusNotes and a reasonable part of your co-worker is not overly dissatisfied working with it: keep using it.

Have you ever had key repeats when using a keyboard?
Actually each PC devices has it's own very specific constraints.
For instance a mouse has to be very reactive and its USB interface has to sustain several hundreds of reports per seconds. But if one is missed, it is often not noticed otherwise (except when it is a mouse click missed).
A keyboard has "opposite" USB constraints. A fast typist usually does not type faster than 20 characters per seconds which translates to 40 reports per second (each key means a report that says key is pressed and another one saying key is released). But we don't want to lose any key.
Some USB hubs sustain some constraints better than others. some USB software drivers for other devices (video cards, etc...) sometimes put huge constraints on USB hubs and have side effects on other devices.
Usually, the best thing to do is to swap the USB port on which the keyboard is plugged, or if the keyboard is plugged on a USB hub, plug directly the keyboard on the root hub of the PC.

An enhanced TreeMap Applet
TreeMap is a way to present information that is very efficient sometimes...
This TreeMap Applet has been enhanced with custom colors and comments using 2 additional xml fields to the standard xml description:
- details for comments when clicking on squares.
- hue / color for discriminating between main groups of squares.

Logitech Cordless Desktop® EX 100: a product I am proud of

I am proud of this keyboard because first of all I like to use it for my daily work. Though I have the opportunity to use all keyboards we are developing at Logitech Switzerland, I like the simplicity, comfort and ease of use of it, especially for it's low-cost price point. I can only recommend it to you.
I am also proud of this keyboard because it has been developed by a junior engineer coming out of school. The embedded software developed for this keyboard is 90% legacy code, and seasoned engineers do not enjoy working on legacy code as much as when they are doing completely new development. This is why I assigned this job to a beginner. She successfully stayed focused on the development of this keyboard and all issues occuring, especially when communicating with development teams in China.

Aube
J'ai écouté pour une dernière fois la respiration profonde des pistons
Appuyé à la fragile main-courante de nickel j'ai senti pour la dernière fois cette sourde vibration des arbres de couche pénétrer en moi avec le relent des huiles surchauffées et la tiédeur de la vapeur
Nous avons encore bu un verre le chef mécanicien cet homme tranquille et triste qui a un si beau sourire d'enfant et qui ne cause jamais et moi
Comme je sortais de chez lui le soleil sortait tout naturellement de la mer et chauffait déjà dur
Le ciel mauve n'avait pas un nuage
Et comme nous pointions sur Santos notre sillage décrivait un grand arc-de-cercle miroitant sur la mer immobile

Universal lua tostring
function table_print (tt, indent, done)
done = done or {}
indent = indent or 0
if type(tt) == "table" then
local sb = {}
for key, value in pairs (tt) do
table.insert(sb, string.rep (" ", indent)) -- indent it
if type (value) == "table" and not done [value] then
done [value] = true
table.insert(sb, "{\n");
table.insert(sb, table_print (value, indent + 2, done))

table.insert(sb, "}\n");
elseif "number" == type(key) then
table.insert(sb, string.format("\"%s\"\n", tostring(value)))

end

end
function to_string( tbl )

return tostring(nil)
elseif "string" == type( tbl ) then
return tbl
elseif "table" == type( tbl ) then
return table_print(tbl)

end
end
Example
print(to_string({"Lua",user="Mariacher",{{co=coroutine.create(function() end),{number=12345.6789}},
func=function() end}, boolt=true}))
This prints
"Lua"
{

{
number = "12345.6789"
}
co = "thread: 0212B848"
}
func = "function: 01FC7C70"
}
boolt = "true"
user = "Mariacher"

"Automatically" test your resume
Here is the opportunity to test your resume: http://jobetic.lingway.info/
The result is in french but it did a pretty good job analyzing mine which is 100% english written.
It understood RTF format much better than pure word/doc format.
