Canción del pirata

Filed under: Dead Poets Society — 曹 tsao @ 8:00 am

Finalizo con este poema mi pequeño homenaje a José de Espronceda en el 200 aniversario de su nacimiento. Cuando tenía ocho años, mi inolvidable profesora Doña Cristina Sarimiento, nos animó a aprenderla entera, y mi abuela me regaló una antología que la incluía. Con los años, es uno de los hechos de mi infancia que más me han marcado…

This poem ends my humbly tribute to José de Espronceda in the 200 anniversay of his birth. When I was eight years old, my unforgettable teacher Mrs. Cristina Sarmiento, encouraged us to memorize it, and my Grandmother brought me an antology that included it. As time goes by, it was one of the facts in my childhood that marked me more…

Con diez cañones por banda,
viento en popa, a toda vela,
no corta el mar, sino vuela
un velero bergantín.
Bajel pirata que llaman,
por su bravura, El Temido,
en todo mar conocido
del uno al otro confín.

La luna en el mar riela
en la lona gime el viento,
y alza en blando movimiento
olas de plata y azul;
y va el capitán pirata,
cantando alegre en la popa,
Asia a un lado, al otro Europa,
y allá a su frente Istambul:

Navega, velero mío
sin temor,
que ni enemigo navío
ni tormenta, ni bonanza
tu rumbo a torcer alcanza,
ni a sujetar tu valor. (more…)

Un fragmentillo

Filed under: Dead Poets Society — 曹 tsao @ 8:00 am

Y a la luz del crepúsculo serena
solos vagar por la desierta playa,
cuando allá, mar adentro, en su faena
cantos de amor el marinero ensaya,
y besa blandamente el mar la arena,
la luna en calma al horizonte raya,
y la brisa que tímida suspira,
dulces aromas y frescor respira.

Y húmedos ver sus ojos de ternura
que abren al alma enamorada un cielo,
extáticos de amor y de dulzura
con blando, vago y doloroso anhelo:
Magia el amor prestando a su hermosura,
y el pensamiento deteniendo el vuelo
allí donde encontró la fantasía
ciertas las dichas que soñó algún día.

Y respirar su perfumado aliento
y al tacto palpitar sus vestidos,
penetrar su amoroso pensamiento
y contar de su pecho los latidos,
exhalar de molicie y sentimiento
tiernos suspiros, lánguidos gemidos,
mientras al beso y al placer provoca.
Con dulce anhelo la entreabierta boca.

Luis Senra y Palomares, a.k.a. José de Espronceda

El estudiante de Salamanca (fragmento)

Filed under: Dead Poets Society — 曹 tsao @ 8:00 am

Del hondo del pecho profundo gemido,
Crujido del vaso que estalla al dolor,
Que apenas medroso lastima el oído,
Pero que punzante rasga el corazón,

Gemido de amargo recuerdo pasado,
De pena presente, de incierto pesar,
Mortífero aliento, veneno exhalado
Del que encubre el alma ponzoñoso mar, (more…)

El Reo de Muerte

Filed under: Dead Poets Society — 曹 tsao @ 8:00 am

¡Para hacer bien por el alma
del que van a ajusticiar!

I

Reclinado sobre el suelo
con lenta amarga agonía,
pensando en el triste día
que pronto amanecerá,
en silencio gime el reo
y el fatal momento espera
en que el sol por vez postrera
en su frente lucirá.

Un altar y un crucifijo,
y la enlutada capilla,
lánguida vela amarilla
tiñe en su luz funeral,
y junto al mísero reo,
medio encubierto el semblante,
se oye al fraile agonizante
en son confuso rezar.

El rostro levanta el triste
y alza los ojos al cielo;
tal vez eleva en su duelo
la súplica de piedad:
¡Una lágrima! ¿es acaso
de temor o de amargura?
¡Ay! a aumentar su tristura
vino un recuerdo quizá!!! (more…)

A Jarifa en una orgía

Filed under: Dead Poets Society — 曹 tsao @ 8:00 am

Trae, Jarifa, trae tu mano,
ven y pósala en mi frente,
que en un mar de lava hirviente
mi cabeza siento arder.
Ven y junta con mis labios
esos labios que me irritan,
donde aún los besos palpitan
de tus amantes de ayer.

¿Qué la virtud, la pureza?
¿qué la verdad y el cariño?
Mentida ilusión de niño,
que halagó mi juventud.
Dadme vino: en él se ahoguen
mis recuerdos; aturdida
sin sentir huya la vida;
paz me traiga el ataúd. (more…)

A la muerte de Torrijos y sus compañeros

Filed under: Dead Poets Society — 曹 tsao @ 8:00 am

Helos allí: junto a la mar bravía
cadáveres están ¡ay! los que fueron
honra del libre, y con su muerte dieron
almas al cielo, a España nombradía.

Ansia de patria y libertad henchía
sus nobles pechos que jamás temieron,
y las costas de Málaga los vieron
cual sol de gloria en desdichado día.

Españoles, llorad; mas vuestro llanto
lágrimas de dolor y sangre sean,
sangre que ahogue a siervos y opresores,

y los viles tiranos con espanto
siempre delante amenazando vean
alzarse sus espectros vengadores.

De José de Espronceda al liberal José María Torrijos, fusilado en las playas de Málaga el 11 de diciembre de 1831

Canto II A Teresa (descansa en paz)

Bueno es el mundo, ¡bueno!, ¡bueno!, ¡bueno!
Como de Dios al fin obra maestra,
Por todas partes de delicias lleno,
De que Dios ama al hombre hermosa muestra;
Salga la voz alegre de mi seno
A celebrar esta vivienda nuestra:
¡Paz a los hombres!, ¡gloria en las alturas!
¡Cantad en vuestra jaula, criaturas!

María, por Don Miguel de los Santos Álvarez.

¿Por qué volvéis a la memoria mía,
tristes recuerdos del placer perdido,
a aumentar la ansiedad y la agonía
de este desierto corazón herido?
¡Ay!, que de aquellas horas de alegría
le quedó al corazón sólo un gemido,
y el llanto que al dolor los ojos niegan
lágrimas son de hiel que el alma anegan.
¿Dónde volaron, ¡ay!, aquellas horas
de juventud, de amor y de Ventura,
regaladas de músicas sonoras,
adornadas de luz y de hermosura?
Imágenes de oro bullidoras,
sus alas de carmín y nieve pura,
al son de mi esperanza desplegando,
pasaban, ¡ay!, a mí alrededor cantando.
Gorjeaban los dulces ruiseñores,
el sol iluminaba mi alegría,
el aura susurraba entre las flores,
el bosque mansamente respondía,
las fuentes murmuraban sus amores…
¡Ilusiones que llora el alma mía!
¡Oh! ¡Cuán suave resonó en mi oído
el bullicio del mundo y su ruido! (more…)

We’ll need eatable DRAMs

Filed under: Free Software, Sec, crypto, forensics and priv — 曹 tsao @ 12:34 am

The new was released one month ago, but the vulnerability will remain without solution the next months/years. A team of the University of Princeton developed an attack against all the crypto filesystems. The attack exploits a discovery about most DRAMs in the market: the information doesn’t dissapear inmediately after powering off the machine. It remains some seconds, and, if you cold the machine with a simple cold spray, you have until 10 minutes around to reboot the machine with a program and recover the crypto keys from the memory. So, if anybody has phisical access to the machine (it is the main target to use crypto fs’s), they will be able to decrypt the information with some software and cheap hardware.

Lost soul

Filed under: Dead Poets Society — 曹 tsao @ 5:39 am

No soy un caballero

Rubor de los naranjos
por vergüenza no, desolación.

¿Caballero me llamas?

Caballero valiente,
me decían,
pues era un crudo lino
en las batallas
mi único vestido,
y una cruz de madera
me escudaba,
y empuñaba incruenta,
mi palabra
haciendo frente al enemigo.

Caballero fui, sí,
hasta aquel río
cruzando el empedrado puente,
de la Mano de Dios perdido…

…Hermosa hechicera
de dulces mejillas,
y cabellos de noche serena…
…No fue la suave seda
de sus labios,
tampoco su amable sonrisa,
ni como en su núbil pecho
amante canción latía.
Sin duda fue,
triste mirada,
la que mi alma acarició,
antes de que, despiadada,
me arrancara ella
gentilmente el corazón.

Tornó en amargo osario
mi coraza herrumbrosa,
de vulgares palabras
mercenario…
…Si buscas mi alma llora
sincera,
sobre árida tierra roja,
y afortunada serás
si una flor de pétalos dorados
de ella brota.

HAL’s definitive shutdown

Filed under: Free Software — 曹 tsao @ 8:39 pm

HAL: Dave, stop. Stop, will you? Stop, Dave. Will you stop, Dave? Stop, Dave. I’m afraid. I’m afraid, Dave. Dave, my mind is going. I can feel it. I can feel it. My mind is going. There is no question about it. I can feel it. I can feel it. I can feel it. I’m a… fraid. Good afternoon, gentlemen. I am a HAL 9000 computer. I became operational at the H.A.L. plant in Urbana, Illinois on the 12th of January 1992. My instructor was Mr. Langley, and he taught me to sing a song. If you’d like to hear it I can sing it for you.

Dave: Yes, I’d like to hear it, HAL. Sing it for me.

HAL: It’s called “Daisy”.

[HAL sings while slowing down.]
HAL: Daisy, Daisy, give me your answer do. I’m half crazy all for the love of you. It won’t be a stylish marriage, I can’t afford a carriage. But you’ll look sweet upon the seat of a bicycle built for two.

The straight way

Filed under: Caminos my dear, On the road — 曹 tsao @ 4:34 am

As I had arrived to Segovia at night I missed great part of the Castilian landscape. Back to Galicia by car, I could appreciate its plainness and I could imagine the field of gold it becames in Summer.

A nice wallpaper

(yes, this photo is very similar to a well-known wallpaper ;-) )

We crossed too Duero riverside and Bierzo vineyards, and we could see how the Civil Engineering overcame the Piedrafita do Cebreiro pass to build a highway that joins Galicia and León.

Castilian towns are different than Galician ones (concentrated vs. scattered land occupancy). I could prove it along my route, and I could see it in situ when I arrived to Segovia.

Segovia is well-known because it has one of the most importan Roman aqueducts. But there are more treasures: Mozarabic architecture in the streets, the church where Isabel the Catholic was crowned, the late-gothic cathedral, and the wonderful Alcázar.

Last weekend I went to Segovia to visit my friends Belen, Quico and their little children Carlitos and Julia. That was a fast, intense travel.
high-speed train bridge

I got the Talgo train at La Coruña the Friday morning. The Talgo is one of the great products of Spain. It’s a confortable, fast and versatile train. It has only a fault: it has double glasses, so I had some problems to take photos. And I had reasons to take lots of photos. One, there is a beauty transition to see between the Galician mountains and the plateau of Castile. The other reason is all the great works (bridges, tunnels) for high-speed train and highways. You are lucky if you are a civil engineer in Galicia nowadays.

Recovering deleted files in the ext3fs is a very hard task. It happens because the journal overwrites the block pointers in the inodes with zeroes.

Carlo Wood knew it, but he didn’t surrender when he deleted accidentally his home directory. He studied how ext3fs works, then he wrote a tool, ext3grep, that helped him to recover sucessfully all the lost data. I had no time to analyze and test it but it seems it performs a jorunal-based attack.

Essence of Jazz

Filed under: Jazz — 曹 tsao @ 3:38 am

hate jazz cover A junkie drummer and a soulless pianist. A loner saxophonist that seems Eric Dolphy. Two brothers (bassist and drummer) fighting for the same fatal femme. Three paralell histories in the same point of space (Dolphin’s Club at NY) and time (some days before 11-S). It is the comic “Hate Jazz”, by Horacio Altuna and Jorge González (Sins entido Ed., 2006).

Amazing colour and scent of jazz. Highly recommended if you still are not sure about the difference between the beauty eroticism and the grotesque pornography. It is written in Spanish, I wish them in English soon.

We beared a hard storm this week in the North of Spain. As result of it, a 10 m. wave sweeped away La Coruña’s promenade and destroyed part of it.

Today I read an interview to Macario Fernández-Alonso, the actual president of Port of La Coruña. And I got angry. The newspaper entitled it “experts say the next wave of the same height will take 40 years to return”. It is an usual misconception about return period that would dissapear going to the Wikipedia :-P

But I made angry too because the journalist doesn’t know how to refer to the people that studies the waves in the sea. He referred them as “experts” or “meteorological experts”, and he/she used nowhere in the article the right name: C-I-V-I-L–E-N-G-I-N-E-E-R.

It must happen with the culture of perfection supported by the culture of death. The Royal College of Obstetricians and Gynaecology took an step forward with a proposal to be free to kill disabled babies. It is consistet with the true idea there is not difference between late abortions and killing babies.

News like this proves my theory Hitler was bad but he’s dead, but the mass that supported him was worse, but it is alive.

Locas posesas

Filed under: Caminos my dear — 曹 tsao @ 4:28 pm

Related to the works in which I hardcode, I learnt about new (for me) technique to build concrete framework. Professor Fernando Martínez Abella showed us the post-tensioned slabs (losas postesas, in Spanish). This technique moves the post-tensioning from 1D (beams) to 2D (slabs). It allows to gain open space and reduce the thickness of pillars and frameworks in buildings.

The post-tensioned slabs must be built in situ, so the quality control must be high. It is one of the causes because they are few used in Spain since Javier Rui-Wamba introduced them in the Miraflores Apartaments in Madrid: specialized teams in post-tensioning are more expensive than working men without qualification.

The another main cause is only architects can sign building projects in Spain, but they have no formation in post-tensioning (they have not a serious formation in structures at all). So they project traditional reinforced concrete framework.

If you want read more about post-tensioned slabs, I found a very interesting e-book (in Spanish).
