The qualities of a formula 1 pilot

Recently, i saw a startup entrepreneur praised as possessing the “qualities of a formula 1 pilot” …

… so,

the man can’t move on his own? no muscles?

needs support of a 1000 kg, multi-million dollar lump of metal around him,

and the support of dozens of people?

burns resources he’s incapable of producing himself?

loves the spotlight? the champagne?

 

hhmm. do i wanna work with him?

 

 

 

 

When mosquitoes time flies and other pests close to the grid, the resulting electrical short circuit current forthwith death …

Sometimes, something as pragmatic as the user guide of a high voltage converter unfolds sheer poetic beauty …

 

DC 3V To 7KV 7000V High Voltage Generator Boost Step-up Power Module

Features:

This is electronic mosquito swatter accessories, internal epoxy resin encapsulated integrated high voltage generator.
It’ll release a certain amount of negative oxygen ions, can produce a high voltage when sterilization, but also purify the air.
Generated by high voltage boost circuit about 7kV (current is less than 10 microamps, harmless to humans and animals), arc distance of about 4mm, electrostatic field with a strong adhesive force between the two grids between the double grid, when mosquitoes time flies and other pests close to the grid, the resulting electrical short circuit current forthwith death.

Specification:

Two 1.5V batteries
Input: DC 3V
Output: 7kV
Outside dimension: 41 x 24 x 17mm (L x W x H)

Wiring:

Short-term connect input voltage, the positive connect to the red line, white line connect to the negative terminal of the battery; long-line output high voltage

Note:

The high-voltage module should avoid the use of electricity in high voltage no-load . Power must be adjusted to a suitable distance to the high-voltage output line , battery capacity is proportional to the distance and the use of the high-pressure arc
Not a voltage as high as possible , you must provide enough current.
Experimental test of the arc distance from short to long , do not exceed the maximum arc distance electricity, energy can not be released due to high pressure , can easily damage the module. )

Package included:

1 x Power module

Shaping our own evolution

Humans Might Already be Evolving into a New Species,

writes Juan Enriquez,

and “According to Enriquez, we take in as much data in a day as we used to see in a lifetime. That type of pressure forces a species to evolve, which likely means our brains are evolving right now to adapt to the new input environment.  … What makes these changes particularly amazing is that our understanding how evolution works means that we can potentially manipulate our own evolution. “It’s a degree of power and responsibility that really forces humanity to think hard about what its doing.”

Having worked with increasing our data flows for about 25 years now,
the substance for me is in the last sentence:

We can in fact shape how we wish to evolve.

Handling data, changing our brains – technicalities.

Intentions and evolutionary goals – the essence.

And it certainly seems while (part of) humanity seems to be on the brink of evolution full of promise,
we seem to fall back into the darkest ages of humanity, at the same time –
clinging to violence, growth, ego –

time to make up our minds.

 

This Time for (or from, rather) Africa

I know it s old, but – does this song ring any bell?

[tube]http://www.youtube.com/watch?v=ibqtKBpSQ3s[/tube]

Right.

“Waka Waka” – theme song of the 2010 football world championships, written by Shakira, Wikipedia says.

The FIFA website states that “the song was written by Shakira, the world-famous singer from Latin America”.

http://en.wikipedia.org/wiki/Waka_Waka_(This_Time_for_Africa)
This topic might seem unrelated to what i normally write about –

but, there are some connections anyway:

1. Sony Music is one of those corps that defend so-called intellectual property against “pirates”, with claws and teeth. Right.

2. It might also be a side somment to the (grossly oversimplified) question sometimes asked: why is Africa poor? Maybe, because we have yet to see african comapnies make millions with stolen european songs?

 

Anyway, there was a song that s always been one of my guilty pleasures – the kind of song you wouldnt admit to liking,
but yes, i have always liked it a lot.

No wonder i thought it sounded really african …
Well hey, if we steal the continents minerals and energy, why not take its music too.

I read that many Cameroonians are really proud this song was chosen as the 2010 anthem – and i ll respect that feeling, of course … but it s almost ironic.

I also read that the original songwriters have been paid some amount of money – i cant help but wonder what share of the total revenue.

 

Others have researched this in more depth than i have – here s some starting points for reading:

the higgs boson

today is a big day for science.
we found a new particle.
just dont get confused – it has nothing to do with god.

also, the fact that we found it doesnt mean it is any more real
than the dreams or thoughts in your head right now.

as the bbc article so aptly said, it might be “something else entirely”.
but it proves our technological ability to design experiments according to our theories,
which then find the objects we designed them to find.

 

if we drill down deeper, we will find more of these.

 

hundreds of years ago there was a man in india, and many after him, who knew all these particles.
they just didnt feel they had to build big big accelerators to prove their existence.

Diaspora* structure – simplified

Diaspora, websockets and nginx




I am installing a #diaspora #pod in Ubuntu 10.04 LTS,
and configuring it to run behind an #nginx (reverse) proxy,
as suggested in

https://github.com/diaspora/diaspora/wiki/Installing-and-Running-Diaspora

Everything works fine, except for some problems with websockets.
While not really essential for diaspora functionality,
#websockets are doing nice things for the web interface,
like updating pages without reload –
e.g. websockets are placing the little “checked” mark when you are adding a person to one of your aspects.

websockets in action on diaspora

As long as i connect direct to the app server,

by going to http://my.server.name:3000

everything is fine –

but through the proxy, the websockets would “hang” –
the little rotating circle would circle for minutes before bringing up the check mark.

The reason for this:

A default install of nginx from Ubuntu repository comes with the following settings in /etc/nginx/nginx.conf:

#keepalive_timeout 0;
keepalive_timeout 65;
tcp_nodelay on;

It is the keepalive_timeout that makes the socket wait –

Slicehost support explains this setting like this

*”The default is very high and can easily be reduced to a few seconds (an initial setting of 2 or 3 is a good place to start and you will rarely need more than that). If no new requests are received during this time the connection is killed.
OK, but what does it mean? Well, once a connection has been established and the client has requested a file, this says “sit there and ignore everyone else until the time limit is reached or you get a new request from the client.
Why would you want a higher time? In cases where there will be a lot of interactivity on the site. However, in most cases, people will go to a page, read it for a while and then click for the next page. You don’t want the connection sat there doing nothing and ignoring other users.”*

source: http://articles.slicehost.com/2008/5/15/ubuntu-hardy-nginx-configuration

So, changing this value to something low or disabling altogether, by doing

keepalive_timeout 0;

will solve this little problem.

G-




Google+ and the nymwars – or why ad agencies do not build good social networks

Note before i start:

Much of this little post i wrote yesterday might be made a little obsolete by today’s interview with Google Executive Chairman Eric Schmidt,

in which he basically explains exactly what i am saying – just in Google speak.

 

http://botgirl.blogspot.com/2011/08/executive-chairman-eric-schidt-admits.html

 

A while ago, while everybody was getting worked up about facebooks privacy crimes, i wrote down a note:

“Any attempt at social networking by organizations whose fundamental interest is not social but profit oriented

will always be flawed. Some will work for us, others we will dump. That is how simple that is.”

 

source: http://botgirl.blogspot.com/

 

 

 

 

 

 

 

 

Some months on, facebook isn’t so much the issue anymore, and we are testing G+.

And getting really annoyed with it.

 

 

One interpretation might be that Google once more is about to demonstrate its incredible ability to get social networks completely wrong,

and sink their next promising attempt in this field, after Wave and Buzz.

 

Sometimes i think they must be running an internal competition in which various subteams come up with great new things

and other departments are asked to wreck it by means of marketing, policy, or timing.

Like some “kill a good idea” shootout.

Anyway, i m sidetracking.

 

 

My old note from above may be formulated even more generic:

 

Problems arise when intention and action are not aligned,

when the reason for a certain activity is not aligned with the motivation behind.

 

These problems typically take the form of increased levels of bullshit, insincerity, misunderstandings, open conflicts.

Many in my field of work (technology, science, networks) see Google as a technology company,

a network company, and – maybe even – a social network company.

It is not.

 

We classify companies according to their core business, their major source of income.

We dont say a pizza shop is in the car business, or in road infrastructure business,

just because they drive out pizzas in a car, via streets and roads.

 

Google is an ad agency with an amazingly strong tech department.

 

Many of Google’s tech products benefit my work incredibly, from search to calendar to G+.

 

I am often enthusiastic about what they come up with in the field of technology, and what other fields they move into –

for example, when they invest in wind and solar farms or networks for the less privileged.

There s a lot to be grateful for.

 

However, that should not obstruct the view on what Google is,

and why they fail at stuff that doesnt align with their core business.

 

Google has a pizza to deliver.

Google has ads to sell.

 

So Google has to be interested in products, profiles, real consumers, real wallets.

 

 

 

 

 

They d like to rank – up with Lady Gaga (despite the name), down with a woman who educates about abuse problems (because of her name).

 

They are not interested in social qualities.

 

(Here, we obviously ignore the naive viewpoint of some mystic upcoming merger between business and social interest – much as we d like to see that coming.)

 

For online security, often abused as a motivator, the “real name” of a person is without any meaning.

Nobody with an understanding of network security will claim that G+’s crusade for true identity adds any protection against cyber evil.

 

For an online community interested in meaningful communications, it s no problem not knowing the “real name” of who you are talking to.

 

For an ad agency, it is.

 

They way they are trying to enforce their interest will mean

 

they ll lose some 10% of their customers (not the world, but significant)

and fail miserably for the other 90%.
