“como um organismo vivo” é o titulo do artigo do expresso sobre o novo livro de António Lobo Antunes Ontem não te vi em Babilónia .
Frase a frase, paragrafo a paragrafo lá vai confirmando que afinal não é assim tão estranho ter largado o que farei quando tudo arde? na página 42, Talvez porque ler Lobo Antunes, é um pouco como lançar-se numa viagem dentro de um barco numa tal noite tempestuosa podendo ver-se apenas por um buraco de fechadura lá para fora. Vai-se olhando para a costa, mas nunca se percebe realmente o que se passou. Apanham-se as imagens ás postas. Ora se estava á direita, ora se está à esquerda, ora se apanham uns segundos de lucidez, de continuidade... sempre “sol de pouca dura”.
Lembro-me de estar a ler e a pensar se o senhor teria comido uma daquelas pastilhinhas brancas que circulam por ai, ou se leu o “como tornar-se doente mental” e nisto optou por um personagem esquizofrénico que publica livros.
Ninguém pode dizer que o senhor “escreve mal” se a escrita se avaliar pela forma como soa. Aquela enxurrada de palavras mal amanhadas acaba por ter o seu quê de melodia. Se olhar para a escrita do lobo Antunes como musica consigo ler e gostar de ler Lobo Antunes. Mas a palavra escrita, narrada, distingue-se da musica porque tem um propósito (por mais ténue que seja), bom.. talvez até a musica instrumental tenha mais propósito que Lobo Antunes...
Tenho a minha fé posta em que com o tempo... Lobo Antunes será uma espécie de cadeira do século XVIII [uma coisa barroca, cheia de floreados] será um artefacto para fazer as delicias de uma elite à procura de “esquisitices”.
É pena já não haver Almada Negreiros para escrever outro Dantas sobre Lobo Antunes...
Escapa à minha capacidade para a razão um motivo de glória para Lobo Antunes.
Lobo Antunes... Pavão Antunes...

Simulaçao de circuitos em linux
Podem esperar gráficos pavorosos e ter de aprender um bocadinho pequenino de spice... mas.. o software é livre, está disponivel para linux e o controlo... sempre é maior que no Orcad...
Depois e sobretudo no que me respeita... em casa não há problemas de privilegios de acesso aos ficheiros.... E se me apetecer mudar o PATH das bibliotecas? se tiver uma minha? Nao posso? tenho de levar o portatil? eek...
hail free software!!
What is gEDA?
The gEDA project is working on producing a full GPL'd suite of Electronic Design Automation tools. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production. Currently, the gEDA project offers a mature suite of free software applications for electronics design, including schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 20 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout.

Watchtower
Dave Mathews band
There must be some way out of here,
Said the joker to the theif.
Theres too much confusion
I cant get nooooooo relief
Business men they,
Drink my wine.
There plowmen dig my earth.
None of them along the line
Know what any of its worth.
No reason to get excited,
The theif he kindly spoke.
There are many among us,
Who feel that life is but a joke (ha ha- ha ha)
But you and I weve been through all that,(yes we have)
And this is not our fate.
So let us not talk falsly *now*,
The hour is getting neaaarrr
And all along the watchtower,
Princes kept the view.
While all the women all the women all the women came and went
Barefoot servatnts too.
Out side in the cold distance,
A wild cat did growl la la la la la
Two riders two riders approaching,
The wind began to howwwwwllll
The theif he take
My money take
The theif he take
My money take
Am I insane
Auf wiedersehen
Am I insane
The theif is safe
No reason to get excited! (yeah!....)

The difference between an introvert and extrovert mathematicians is: An introvert mathematician looks at his shoes while talking to you. An extrovert mathematician looks at your shoes.

Deep pression
ohh well.. Shit does happen in this life... But then again, you can't surrender to these situations every time and ultimately if you try hard enough a day after the other... Somehow, they become obsolete.
Best way for this H. person to get her mind out of it:
run a google search on "mathematical" + "humor"!
I'll post some more, (some other day ), so that this post does not loose it's purpose of small reference, and becomes to long for the rushing reader to follow.
Plus these... Some Mathematical Proofs
The following is a list of some common proof techniques that are often extremely useful.
1. Proof by example:
The author gives only the case n = 2 and suggests that it contains most of the ideas of the general proof.
2. Proof by intimidation:
'Trivial.'
3. Proof by vigorous handwaving:
Works well in a classroom or seminar setting.
4. Proof by cumbersome notation:
Best done with access to at least four alphabets and special symbols.
5. Proof by exhaustion:
An issue or two of a journal devoted to your proof is useful.
6. Proof by omission:
'The reader may easily supply the details.'
'The other 253 cases are analogous.'
'...'
7. Proof by obfuscation:
A long plotless sequence of true and/or meaningless syntactically related statements.
8. Proof by wishful citation:
The author cites the negation, converse, or generalization of a theorem from literature to support his claims.
9. Proof by funding:
How could three different government agencies be wrong?
10. Proof by eminent authority:
'I saw Karp in the elevator and he said it was probably NP-complete.'
11. Proof by personal communication:
'Eight-dimensional colored cycle stripping is NP-complete [Karp, personal communication].'
12. Proof by reduction to the wrong problem:
' To see that infinite-dimensional colored cycle stripping is decidable, we reduce it to the halting problem.'
13. Proof by reference to inaccessible literature:
The author cites a simple corollary of a theorem to be found in a privately circulated memoir of the Slovenian Philological Society, 1883.
14. Proof by importance:
A large body of useful consequences all follow from the proposition in question.
15. Proof by accumulated evidence:
Long and diligent search has not revealed a counterexample.
16. Proof by cosmology:
The negation of the proposition is unimaginable or meaningless.
Popular for proofs of the existence of God.
17. Proof by mutual reference:
In reference A, Theorem 5 is said to follow from Theorem 3 in reference B, which is shown from Corollary 6.2 in reference C, which is an easy consequence of Theorem 5 in reference A.
18. Proof by metaproof:
A method is given to construct the desired proof. The correctness of the method is proved by any of these techniques.
19. Proof by picture:
A more convincing form of proof by example. Combines well with proof by omission.
20. Proof by vehement assertion:
It is useful to have some kind of authority in relation to the audience.
21. Proof by ghost reference:
Nothing even remotely resembling the cited theorem appears in the reference given.
22. Proof by forward reference:
Reference is usually to a forthcoming paper of the author, which is often not as forthcoming as at first.
23. Proof by semantic shift:
Some standard but inconvenient definitions are changed for the statement of the result.
24. Proof by appeal to intuition:
Cloud-shaped drawings frequently help here.

Barcelona
Pois é estive em barcelona de quinta a segunda. Andei de avião pela primeira vez...
A viagem para lá foi pior, uma dor de ouvidos capaz de me levar á loucura. Depois de sobreviver a dois jantares de guardanapo de pano [Tenho uma aversão visceral a estas coisas, sobretudo porque nao sei muito bem como me comportar nessas situações.... Tentei estar o mais calada e o mais atenta possível!], fizemos as malas e zarpamos para a liberdade.
Nos primeiros dias a acrescer ao cansaso psiquico, houve também o fisico. De quinta a sabado vimos Barcelona naquela perspectiva tipica do turista. Arriscaria a dizer que conheço neste momento melhor as Ramblas que a baixa de lisboa de tanto andar ás voltas para cima e para baixo, de olhos esbugalhados e espirito estarrecido.
No sabado fiquei sozinha com a minha irmã. Ela tem um despreendimento em relação a sitios desconhecidos que nao consigo partilhar e portanto segui-a semi relutante, mas fui. Tive a sensação de viverem ali mundos paralelos adjacentes. Há uma fachada turistica e mesmo ao lado, naquelas ruas mais estreitas de perdios escuros e menos cuidados, um outro universo mais comum. Digo, humano! [com o que isso tem de bom e de mau]. Sem mencionar a quantidade de muçulmanos e indianos, que quase excede os espanhois nas ruas. Há também as coisas caracteristicas destes: deparamos com quase tudo, sex-shops aos montes, "lojas dos 300", artigos de artesanato [brazileiro, inca...]. Um tipo de variedade [com qualidade] impossivel de encontrar em lisboa.
Paramos quase em todas as esquinas para ouvir pelo menos um pouco de musica gratuita. Há tipos a tocar viola e violino em todo o lado. E nada de "ai se elas querem um abraço ou um beijinho..", ouvimos bach e vivaldi... Se os espanhois tem pimba escondem-na bem. Ainda vimos também um concerto [pago... bom. valeu o dinheiro] de guitarra espanhola na "Basilica del PI".
De resto.. nunca tinha sido tao assediada. Quase fiquei paranoica com tanto avontade para aquele tipo de comentarios descarados e olhos nos olhos.
Gostei tanto da cidade que fiquei com vontade de me mudar para lá. Há outra vida! Digo no sentido da iniciativa, que nós não temos. Nos 4 dias deparamos com 3 manifestações. Duas de trabalhadores e uma de anarcas. As tres comportavam uma multidão capaz de encher a avenida da liberdade. Duas delas traziam também tambores e toda a gente seguia em rubro, cantando e gritando... Há amor próprio em Espanha.
