With access to supercomputers, researchers at work on models to predict global climate change are able to account for the big effects of fluid flows occurring on a small scale. In this image, researchers see how small scales, in fact, develop an interesting layered structure, indicated by fluid sloshing back and forth (red moving to the right and blue moving to the left).

Retrocomputing (a portmanteau of retro and computing) is the use of early computer hardware and software today. Retrocomputing is usually classed as a hobby and recreation rather than a practical application of technology; enthusiasts often collect rare and valuable hardware and software for sentimental reasons. However some do make use of it.[1] Retrocomputing often gets its start when a computer user realizes that expensive fantasy systems like IBM Mainframes, DEC Superminis, SGI workstations and Cray Supercomputers have become affordable on the used computer market, usually in a relatively short time after the computers' era of use.

Arsenal (Vienna)
The Vienna Arsenal, object 1
(Pictures you can see by clicking on the link at the end of page!)
The Arsenal in Vienna is a former military complex in the southeast of the city, located in the 3rd district of Vienna. The mighty, consisting of several brick buildings facility is located on a rectangular plan on a hill south of the Country Road Belt (Landstraßer Gürtel).
Meaning
The Arsenal is the most important secular assembly of Romantic Historicism in Vienna and was conducted in Italian-Medieval and Byzantine-Moorish forms. Essentially the complex is preserved in its original forms; only the former workshop buildings within the bounding, from the the outside visible wings were replaced by new constructions.
History to 1945

The complex, with a total of 31 "objects" (buildings) was built from 1849 to 1856 on the occasion of the March Revolution of 1848 and was the first building of the fortress triangle, replacing the old Vienna's city walls, with the Rossauer Barracks and the now-defunct Franz Joseph barracks at Stubenring. These buildings should not serve to deter foreign enemies from the city, but to secure state power in the event of revolutionary upheavals in Vienna. The decision to build the Arsenal, it came from the 19-year-old Emperor Franz Joseph I who on 2 December 1848 had come to the throne.
The design for the Imperial Artillery Arsenal came from General Artillery Director Vincenz Freiherr von Augustin, to which, subsequently, the site management had been transferred. Under his leadership, the buildings under assignment of sectors have been planned of the architects Carl Roesner, Antonius Pius de Riegel, August Sicard von Sicardsburg, Eduard van der Nüll, Theophil von Hansen and Ludwig Förster and built by the company of the architect Leopold Mayr.
From 1853 to 1856, Arsenal church was built by the architect Carl Roesner. The K.K. Court Weapon Museum, later K.K. Army Museum, now Museum of Military History, housed in a separate representative free-standing wing, was completed structurally in 1856, but was only in 1869 for the first time accessible.
For the construction of the Arsenal 177 million bricks were used. Construction costs totaled $ 8.5 million guilders. In the following years, there have been extensions. During the two world wars, the complex served as a weapons factory and arsenal, especially as barracks.
The record number of employees in Arsenal was reached in the First World War, with around 20,000 staffers. After 1918, the military-industrial operation with own steel mill was transformed into a public service institution with the name "Austrian Factories Arsenal". However, there were almost insoluble conversion problems in the transition to peacetime production, the product range was too great and the mismanagement considerable. The number of employees declined steadily, and the company became one of the great economic scandals of the First Republic.
By the fall of 1938, the area belonged to the 10th District Favoriten. However, as was established during the "Third Reich" the Reich District of Greater Vienna, became the arsenal complex and the south-east of it lying areas in the wake of district boundary changes parts of the 3rd District.
During the Second World War, in the Arsenal tank repair workshops of the Waffen-SS were set up. In the last two years of the war several buildings were severely damaged by bombing. During the Battle of Vienna, in the days of 7 to 9 April 1945, was the arsenal, defended by the 3rd SS Panzer Division "Totenkopf", focus of the fighting, the Red Army before its victory facing heavy losses.
History since 1945
Ruins of the object 15 after the air raids 1944
Deposits at the Arsenal Street
After heavy bomb damages during the Second World War, the buildings of the Arsenal were largely restored to their original forms.
In the southern part and in the former courtyard of the arsenal several new buildings were added, among them 1959-1963 the decoration workshops of the Federal Theatre designed by the architects Erich Boltenstern and Robert Weinlich. From 1961 to 1963, the telecommunications central office was built by the architect Fritz Pfeffer. From 1973 to 1975 were built operation and office building of the Post and Telephone Head Office for Vienna, Lower Austria and Burgenland (now Technology Centre Arsenal of Telekom Austria) with the 150-meter high radio tower in Vienna Arsenal according to the plans of architect Kurt Eckel. In the 1990s, a rehearsal stage of the Castle Theater (Burgtheater) was built according to plans by Gustav Peichl.
Also the Austrian Research and Testing Centre Arsenal, now Arsenal Research, which has made itself wordwide a celebrity by one of the largest air chambers (now moved to Floridsdorf - 21st District), was housed in the complex. A smaller part of the complex is still used by the Austrian army as a barracks. Furthermore, the Central Institute for Disinfection of the City of Vienna and the Central Chemical Laboratory of the Federal Monuments Office are housed in the arsenal. The Military History Museum uses multiple objects as depots.
In one part of the area residential buildings were erected. The Arsenal is forming an own, two census tracts encompassing census district, which according to the census in 2001 had 2.058 inhabitants.
End of 2003, the arsenal in connection with other properties of the Federal Property Society (BIG - Bundesimmobiliengesellschaft) was sold to a private investor group. Since early 2006, the lawyer of Baden (Lower Austria, not far away from Vienna) Rudolf Fries and industrialist Walter Scherb are majority owners of the 72,000 m2 historic site that they want to refurbish and according to possibility rent new. Fries also plans to enlarge the existing living space by more than a half (about 40,000 m2).
An architectural design competition, whose jury on 28 and 29 in June 2007 met, provided proposals amounting to substantial structural changes in the complex. Such designed competition winner Hohensinn a futuristic clouds clip modeled after El Lissitzky's cloud bracket, a multi-level horizontal structure on slender stilts over the old stock on the outskirts of the Swiss Garden. The realization of these plans is considered unlikely.
Some objects are since 2013 adapted for use by the Technical University of Vienna: Object 227, the so-called "Panzerhalle" will house laboratories of the Institute for Powertrains and Automotive Technology. In object 221, the "Siemens hall", laboratories of the Institute for Energy Technology and Thermodynamics as well as of the Institute for Manufacturing Technology and High Power Laser Technology are built. In object 214 is besides the Technical Testing and Research Institute (TVFA) also the second expansion stage of the "Vienna Scientific Cluster" housed, of a supercomputer, which was built jointly by the Vienna University of Technology, the University of Vienna and the University of Agricultural Sciences.
Accessibility
The arsenal was historically especially over the Landstraßer Gürtel developed. Today passes southeast in the immediate proximity the Südosttangente called motorway A23 with it connection Gürtel/Landstraßer Hauptstrasse. Southwest of the site runs the Eastern Railway, the new Vienna Central Station closes to the west of the arsenal. Two new bridges over the Eastern Railway, the Arsenal Stay Bridge and the Southern Railway bridge and an underpass as part of Ghegastraße and Alfred- Adler-Straße establish a connection to the on the other side of the railway facilities located Sonnwendviertel in the 10th District, which is being built on the former site of the freight train station Vienna South Station.
On the center side is between Arsenal and Landstraßer Gürtel the former Maria Josefa Park located, now known as Swiss Garden. Here stands at the Arsenal street the 21er Haus, a branch of the Austrian Gallery Belvedere, on the center-side edge of the Swiss Garden has the busy suburban main railway route the stop Vienna Quartier Belvedere, next to it the Wiener Linien D (tram) and 69A (bus) run.

Okay it might not look as turbulent as the plasma but the system IS turbulent. BTW it's not a photograph. It's a plot from the simulations I do. It looked pretty so I thought I'll share it.
I work in computational plasma physics. I work with so called hybrid plasma codes which we generally run on huge supercomputers with thousands of processors. The main purpose of doing this is to understand the basic nature of turbulent plasmas and in turn apply our understanding to Solar Wind which affects our space weather which is important to predict if we want to make sure that our satellites and astronauts are safe up there. A strong solar storm can also have unpleasant effects on earth.
I know I know too much of geeky stuff here but I hope that you'll agree with me that the picture is pretty anyway :)

Powerful supercomputers are the latest tools in the box for engineers designing the next generation of nuclear reactors. This simulation modeled the flow of coolant in part of a reactor that would "recycle" used nuclear fuel. Red is high velocity and blue is low velocity. Performed on Argonne's Blue Gene/P supercomputer at the Argonne Leadership Computing Facility.
--more details--
This image simulates flow into the upper plenum of an advanced recycling nuclear reactor. Red represents high velocity; blue, low. Coolant enters from hexagonal channels at the plenum as two jets and exits from a single rectangular channel at the top. Simulations provide insight into the flow’s thermal-hydraulic properties. This simulation was performed using the Nek5000 code with 68,826 spectral elements of order 7 and run on 8192 cores of the Blue Gene/P at the Argonne Leadership Computing Facility.
This is a little different view of "Talon".
It is an IBM iDataPlex with 3072 cores of Intel Westmere X5660 processor cores, 6TB of memory and a peak performance of 34.4 trillion calculations per second.

The installation of a new supercomputer demands the expertise of individuals with diverse knowledge sets. As projects evolve, diverge, and grow, they require a special kind of talent to fit certain pieces together. When it comes to scientific codes and software, they require someone who knows computers and science—someone like Mark Berrill, a computational scientist in the Scientific Computing Group (SciComp) at the Oak Ridge Leadership Computing Facility (OLCF).

"Guarda che ce l'ha quello con la giacca blu, l'ha appena messo nel taschino."
"Ma sei sicura? Hanno detto che era solo a livello sperimentale, che non si poteva ancora avere in commercio."
"Ce l'ha lui, l'ho visto, l'ho riconosciuto, l'ho visto in tv; quella forma oblunga, sembra una specie di biro, con alla fine due puntine di ferro."
"Giada, sei la mia cameriera da anni. E' vero che ti ho sempre trattata bene?"
Giada guardò il suo capo, un omone grande e grosso, che a volte le aveva fatto paura, specie all'inizio.
"Beppone, a volte mi hai un po' spaventata, agli inizi."
"Ma poi ti è passato vero? Ora non più?"
"Vero, ora non più, ho imparato a conoscerti, so che sei irascibile ma con me sempre buono."
Beppone tirò un sospiro di sollievo.
Era una comitiva di trentacinque persone e uno di loro poteva avere l'arnese.
Anche lui ne aveva sentito parlare, dell'arnese; sembrava impossibile che lo realizzassero, sembrava irraggiungibile; evidentemente con qualche diavoleria elettronica erano riusciti a costruirlo.
Ne aveva parlato con i suoi colleghi ristoratori; "Se lo producono è la fine", diceva qualcuno, altri invece dicevano "No, questo è l'inizio, ci voleva, ora vediamo chi sa lavorare."
Tutto era cominciato pochi mesi prima, molto lontano, negli eleganti tavoli dirigenziale di una mega-company statunitense, si parlava di una fusione importante.
Sul tavolo due soluzioni, una antitetica all'altra.
Una proposta da una donna, l'altra dall'uomo.
Aveva vinto la donna.
La fusione del secolo, l'avevano chiamata.
L'uomo non era abituato a perdere; la sua proposta era chiaramente economicamente migliore, come poteva aver vinto la donna? Quali armi aveva utilizzato?
Così, a decisioni prese, appena fuori dalla riunione, chiese ad uno degli azionisti cosa l'aveva fatto votare per lei.
"Vedi, è semplice. Guardala. Ha ragione, è chiara, spiega le cose bene, è luminosa; si vede che conosce la materia. Io non posso conoscere tutti i numeri; ma la direzione che ci ha indicato mi sembra buona. La tua era sicuramente corretta, tecnicamente, magari anche vantaggiosa; ma non 'sapeva di futuro'; le sue parole, invece, odoravano di sano, di possibilità ".
Chiese ancora ad altri: stesse risposte, più o meno, una fiducia incondizonata in quella persona.
Decise di parlare alla donna; la trovò straordinariamente radiosa ed elegante, motivo in più per rimanerci male al rifiuto ad un invito a cena.
L'uomo aveva ormai una certa età ed aveva finito si essere caparbio; sapeva che prima o poi i nodi vengono al pettine e se ne andò a testa bassa.
Lo incrociò un collega dello staff avversario, con cui aveva lavorato anni addietro.
"Hey, che viso triste... non te la prendere, lo sai che capita."
"Si, vero, capita. Devo ritirarmi per meditarci un po' sopra."
"Meditarci? Andiamo a berci una birra, piuttosto."
"No... un'altra volta."
"Ok va bene, ma via quel muso... questa volta non potevi vincere."
L'uomo alzò il livello di attenzione.
"Come non potevo? Non sembrava buona la mia soluzione?"
"Si, certo, ma lei aveva un'arma che, evidentemente, tu non conosci."
"Cioè?"
Il collega rispose con un sorriso.
"Cioè? Non ho capito, spiega!"
Il collega capì di essere andato un po' oltre; ma l'uomo era un amico, ed il 'segreto' non era poi così tanto un segreto, la voce si stava diffondendo.
Così lo prese in disparte e i due si appartarono sul divanetto di un bar.
"Adesso mi spieghi cos'aveva."
"Beh... ti sembrerà una cosa stupida, per cui non te la prendere con me. E poi fai finta che non te l'abbia detto, siamo concorrenti."
"Va bene, parla."
"Lei è arrivata stamane dall'Europa."
Il collega aspettò per vedere segni di comprensione sul viso dell'amico.
"E allora?"
Proseguì, sperando che qualche voce gli fosse arrivata.
"Dalla Provenza; ieri era là ."
"Mi stai prendendo in giro? Cosa c'entra?"
"Come, non sai proprio nulla?"
"Nulla di cosa?!?"
"Ha cenato alla Tavola di Viviana."
"La smetti di prendermi in giro? Cosa vuol dire? Cos'è questa tavola? Cosa c'entra con la fusione?"
"Vedo che proprio non t'è arrivata alcuna notizia in merito. La Tavola di Viviana è un ristorante, in Provenza, nella Francia del Sud. Sembra che le persone che pranzano lì per qualche tempo stiano molto bene, diventino quasi luminose, e nel parlare, nel consigliare del comunicare in genere diventano dolci, credibili, convincenti."
"Ma che stupidata!"
"Sì, una stupidata che ha fatto perdere al tuo cliente qualche milione di dollari."
La Tavola di Viviana era un ristorantino sulle colline della Provenza; la proprietaria, Viviana appunto, gestiva il locale aiutata da due ragazzotti, un maschio ed una femmina, ed un cuoco.
In una vita precedente Viviana aveva accumulato denaro; nessuno sapeva bene come.
Arrivata ai cinquanta decise di averne abbastanza e aprì questa locanda curandone l'arredamento, le forniture e, soprattutto, il personale.
Viviana aveva un modo di fare avvolgente; con chiunque parlasse sembrava prendersene cura, ben al di là delle circostanze.
Soprattutto i due ragazzi ed il cuoco ne erano coinvolti; si sentivano totalmente amati e rispettati da questa donna più anziana che procurava loro il lavoro e spesso si preoccupava anche delle loro esigenze extralavorative.
Non solo ne erano coinvolti; anche quando parlava con un fornitore, Viviana si preoccupava prima della persona, poi dei prodotti; tanto che molti uomini pensavano che li stesse filando, ma presto si accorgevano che le attenzioni non erano in quella direzione.
Così dopo qualche anno anche i fornitori diventarono amici, e passavano da Viviana anche oltre gli orari delle consegne.
I prodotti che portavano erano sempre i migliori a disposizione ed i più freschi.
Gli occhi calmi di Viviana, la bontà del cibo, l'allegria dei due ragazzi, il pacioso lavoro del cuoco fischiettante nella cucina a vista e la calma delle colline costituivano un ambiente tranquillo in cui molti volentieri si fermavano per un pranzo o una cena.
Certo in molti notarono l'effetto che quei pasti avevano sulle persone, ma solo dopo qualche tempo nacque la leggenda della locanda 'magica', cioè il posto dove nutrirsi per sentirsi meglio.
Nei periodi successivi ai pasti le persone stavano meglio, splendevano; tutti lo notavano, e questo splendore si rifletteva sulle rispettive famiglie e sugli ambienti di lavoro; non ci volle molto perchè tutti capissero come un pasto da Viviana fosse il toccasana nel caso si dovessero risolvere problemi o affrontare situazioni difficili; una specie di cura.
Lo stesso capitò alla donna della riunione di cui vi ho raccontato; cenò qui la sera ed il giorno dopo vinse la sua battaglia per la fusione.
Ora devo dirvi che sono Gerbero Vallanzani e faccio il ricercatore; sono quello con la giacca blu di cui avete letto all'inizio.
Non mi prendete in giro per il nome, a me piace.
Ma per spiegarvi cos'ho nel taschino, e perchè terrorizza l'oste che ho davanti, devo ancora dirvi un paio di cose.
Anch'io avevo sentito parlare di questa leggenda della Tavola di Viviana; vivevo da quelle parti e così, in una bella giornata d'agosto, mi sono seduto sotto le piante della locanda per pranzare.
Cibo senza grandi pretese, ma indubbiamente buono, ambiente cordiale, giornata tranquilla; a dire il vero, nulla di eccezionale oltre ad un diffuso senso di benessere.
Dopo il pranzo, quel giorno avevo lezione, spiegavo fisica atomica in istituto e... finita l'ora tutti i ragazzi sorridevano, addirittura qualcuno mi ha ringraziato per la chiarezza della spiegazione. Normalmente sono abbastanza noioso, lo so, nelle spiegazioni; quella volta invece mi sentii come il mago dei docenti.
Qualche parola con i colleghi.. l'effetto funzionava ancora! La sera a casa con la famiglia... magia! Riuscivo a parlare bene, chiaro, ad essere allegro e fiducioso, a parlare anche di sventure in modo risolutivo e conciliante.
Visto che sono ricercatore, ricerco.
Così sono tornato più volte alla Tavola di Viviana; e ho sperimentato che l'effetto 'magico' in effetti funzionava; a volte in modo più, marcato, a volte meno: ma funzionava.
Un giorno non ha funzionato.
Sono andato, ho pranzato, sono stato servito dalla ragazza un po' più corrucciata del solito e, al pomeriggio, nessun effetto.
Sono tornato il giorno dopo e c'era un cartello, 'siamo chiusi'.
Ho incrociato Viviana che stava uscendo, le ho chiesto il motivo.
Alla risposta che mi ha dato ho dapprima riso un po', poi, di fronte al suo viso serio, ho smesso.
"E morto il gatto della cameriera."
"Si.. certo.. ma se muore il gatto voi chiudete?"
"Si, volevo già chiudere ieri che stava male."
"Come? Chiudete il ristorante per un gatto malato?"
"Certo. Può un fiume 'restare aperto' se non ha acqua? Può un prato 'restare aperto' se non ha erba?"
"EH?"
L'ho guardata bene; aveva un po' gli occhi di una pazza.
Conosco bene quello sguardo.
Ho conosciuto centinaia di ricercatori di tutto il mondo, e conosco bene lo sguardo di chi ha visto oltre; lei aveva quegli occhi.
Ho abbassato i miei, come chi si arrende di fronte ad una potenza superiore.
E ho chiesto: mi dica, mi spieghi, sono un ricercatore.
"Ho aperto un distributore di felicità attraverso questo ristorante; i cibi sono estremamente ricettivi, se le persone che li preparano e li servono sono felici, questa felicità si moltiplica e passa nei cibi che a loro volta la portano ai miei clienti. Semplice. Gatto morto, ragazza infelice, gioco finito. Scusi devo andare."
"Ma aspetti!! Come! Come l'ha scoperto? Dove va? un attimo!"
"Ho passato una vita a dare felicità alle persone, e questo mi ha riempito la vita di gioia. Ho voluto inventare un metodo per darne di più di quella che posso regalare singolarmente. Col ristorante sono riuscita. Torni dopodomani, dopo i funerali riapriremo e le dirò di più."
Che donna! Incredibile! Che forza!
Che... roba impossibile, ma che dice, che vaneggia? Erogare felicità ! Come fosse un distributore! Col cibo! Che baggianate!
Ma... e se fosse vero? La maggior parte delle scoperte scientifiche sono state fatte da chi ha smesso di credere alle certezze.
Così nei giorni successivi ho fatto il ricercatore della felicità ; ho utilizzato metodi scientifici per cercare di trovare se la felicità fosse presente nei cibi.
Naturalmente non ne ho parlato con il mio capo, nè ho pensato di pubblicare i miei studi.. mi avrebbero tutti presi in giro.
Dal punto di vista scientifico qualcosa esiste se ha un effetto misurabile; sono partito da questo punto e ogni tanto prendevo qualche cibo dalla locanda e lo portavo in laboratorio, procurandomene un altro identico da confrontare. Sono riuscito anche ad averne qualcuno dallo stesso fornitore della locanda, proveniente dalle stesse origini.
Ho piantato un paio di elettrodi nei due cibi e ho provato a registrare le microcorrenti che potevano formarsi, oppure ad iniettare segnali a diversa frequenza e ampiezza d'onda, ma non ho avuto risultati.
Da qualche giorno abbiamo a disposizione in laboratorio potenze computazionali enormi, messe a disposizione da un progetto europeo; tramite rete, possiamo accedervi.
Le ho usate in questo modo: ho inviato nei cibi segnali di diversa fequenza e modulazione varianti per valori discreti ed incrociati in modo semicasuale e ho registrato eventuali microcorrenti che potessero generarsi in risposta.
Ho registrato dati per due giorni per mille variazioni al secondo, con tutte le possibili combinazioni che sono riuscito a generare.
Quindi ho impacchettatto il tutto in un set di dati elaborabile dai supercomputer.
Ho aspettato la tarda sera quindi ho messo insieme tutta la potenza che avevo a disposizione: 15000 CPU per 12 TeraFlops, gli ho dato in pasto il set di dati, l'ha elaborato per 25 secondi e mi ha dato la risposta.
La risposta era positiva: effettivamente poteva esistere una combinazione di segnali che iniettata stimolava nel cibo 'felice' una reazione diversa dal cibo 'campione'.
Quella notte l'ho passata in laboratorio.
Ho lavorato sui dati e scomposto la sequenza di frequenze 'discriminanti', quelle che davano risposte diverse nei due cibi.
Il segnale disriminante era composto da una dozzina di frequenze diverse nello spettro udibile.
Me lo appuntai su un foglio: sono 'una dozzina di frequenze diverse nello spettro udibile'.
Osservai il foglio e poi mi guardai allo specchio e mi misi a ridere; i ricercatori si perdono sempre in un bicchier d'acqua!
'Frequenze dello spettro udibile'!! Note, sono note!!! Note musicali, che scemo!!
Ne feci un file WAV musicale, indossai le cuffie e ancora un po' cadevo a terra dallo stupore a sentire quelle dodici frequenze
Mi sarei aspettato di tutto ma... "fra Martino campanaro!!!" com'era possibile?
Eppure... la prova sperimentale funzionava: iniettando nel cibo quella serie di frequenze quello 'felice' rispondeva, l'altro taceva.
Indagando, scoprri che in genere qualsiasi buona musica iniettata nelcibo 'felice' dava reazioni che non erano presenti nel cibo campione.
Avevo inventato il... misuratore di felicità nei cibi!
Da allora ho provato e riprovato: funziona.
Non c'è ancora uno sviluppo industriale, ma qualche testata giornalistica se n'è interessata; prima come scoop, ora più seriamente.
Ciò che è successo dopo, è stato incredibile.
Il misuratore è stato dapprima messo a disposizione per i laboratori di misura; il sistema di rilevamento delle microcorrenti è molto complesso e costoso e quindi solo i grandi laboratori potevano averlo.
Qualche albergatore, fiutato l'affare, ha voluto fare misurare i propri cibi; cibi che, in qualche caso, effettivamente rispondevano positivamente come 'contenenti felicità '.
A questo punto risultò facile a qualcuno pubblicizzare il proprio 'ristorante felice' ed avere molti clienti.
La situazione per questi ristoratori è oggi però totalmente precaria; è difficile avere del cibo felice perchè ci vogliono fornitori felici e personale felice, e basta un nonnulla per rovinare la catena della felicità ; se, per esempio, una cassa di limoni pur biologici e naturali viene presa a calci dall'addetto di un magazzino, sarà quasi impossibile trasformarla in cibo felice, ed il succo contaminerà gli altri cibi.
Se un cameriere è sottopagato o trattato male, sarà impossibile che possa servire cibo felice; anzi, rischia di rovinare il cibo felice esistente.
In un primo tempo i 'ristoranti felici' erano carissimi; ma non sono sopravvissuti, non è solo un detto che 'il denaro non dà la felicità '; se n'è avuta dimostrazione.
Tutto il settore è in subbuglio; tutti i clienti vogliono cibo felice, e se i misuratori portatili diventeranno una realtà , ci si aspetta una rivoluzione nella modalità di somministrare alimenti.
Allo stesso tempo gestire un ristorante diventa una professione di una raffinatezza indicibile; non solo la capacità culinaria, ma psicologia e saggezza diventano doti necessarie.
Qualche ristoratore se la ride, e continua a fare affari perchè da sempre offre cibo felice; altri.. non ridono.
Ora sto testando il primo dispositivo portatile prodotto... e quindi capite perchè l'oste è così preoccupato... e perchè lo sguardo di Viviana mi è ancora così impresso nei ricordi.

Retrocomputing (a portmanteau of retro and computing) is the use of early computer hardware and software today. Retrocomputing is usually classed as a hobby and recreation rather than a practical application of technology; enthusiasts often collect rare and valuable hardware and software for sentimental reasons. However some do make use of it.[1] Retrocomputing often gets its start when a computer user realizes that expensive fantasy systems like IBM Mainframes, DEC Superminis, SGI workstations and Cray Supercomputers have become affordable on the used computer market, usually in a relatively short time after the computers' era of use.
en.wikipedia.org/wiki/Retrocomputing
Con il termine retrocomputing si indica una attività di "archeologia informatica" che consiste nel reperire, specialmente a costi minimi, computer di vecchie generazioni, che hanno rappresentato fasi importanti dell'evoluzione tecnologica, ripararli se sono danneggiati, metterli nuovamente in funzione e preservarli.
The OLCF’s newest supercomputer, Summit, is starting to take shape. The first cabinets have arrived and are being installed.

Arsenal (Vienna)
The Vienna Arsenal, object 1
(Pictures you can see by clicking on the link at the end of page!)
The Arsenal in Vienna is a former military complex in the southeast of the city, in the 3rd District of Vienna located. The mighty, consisting of several brick buildings facility is located on a rectangular plan on a hill south of the country Strasser belt (Landstraßer Gürtel).
Meaning
The Arsenal is the most important secular assembly of Romantic Historicism in Vienna and was conducted in Italian-Medieval and Byzantine-Moorish forms. Essentially the system is preserved in its original forms; only the former workshop buildings within the bounding, from the the outside visible wings were replaced by new constructions.
History to 1945

Vienna Arsenal (Museum of Military History)
Arsenal, with HGM (Heeresgeschichtliches Museum) from the East
The plant, with a total of 31 "objects" (buildings) was built from 1849 to 1856 on the occasion of the March Revolution of 1848 and was the first building of the fortress triangle, the old Vienna's city walls replacing, with the Rossauerstrasse Barracks and the now-defunct Franz Joseph barracks at Stubenring. These buildings should not serve to deter foreign enemies from the city, but to secure state power in the event of revolutionary upheavals in Vienna. The decision to build the Arsenal, it came from the 19-year-old Emperor Franz Joseph I who on 2 December 1848 had come to the throne.
The design for the Imperial Artillery Arsenal came from General Artillery Director Vincenz Freiherr von Augustin, which, subsequently, the site management had been transferred. Under his leadership, the buildings under allocation of sectors have been planned of the architects Carl Roesner, Antonius Pius de Riegel, August Sicard von Sicardsburg, Eduard van der Nüll, Theophil von Hansen and Ludwig Förster and built by the company of the architect Leopold Mayr.
From 1853 to 1856, Arsenal church was built by the architect Carl Roesner. The K.K. Court Weapon Museum, later K.K. Army Museum, now Museum of Military History, housed in a separate representative free-standing wing, was completed structurally in 1856, but was only in 1869 for the first time accessible.
For the construction of the Arsenal 177 million bricks were used. Construction costs totaled $ 8.5 million guilders. In the following years, there have been extensions. During the two world wars, the complex served as a weapons factory and arsenal, especially as barracks.
The record number of employees in Arsenal was reached in the First World War, with around 20,000 staffers. After 1918, the military-industrial operation with own steel mill was transformed into a public service institution with the name "Austrian art arsenal". However, there were almost insoluble conversion problems in the transition to peacetime production, the product range was too great and the mismanagement considerable. The number of employees declined steadily, and the company became one of the great economic scandals of the First Republic.
By the fall of 1938, the area belonged to the 10th District Favoriten. However, as was established during the "Third Reich" the Reich District of Greater Vienna the arsenal complex and the south-east of it lying areas in the wake of district boundary changes became parts of the 3rd District.
During the Second World War, in the Arsenal tank repair workshops of the Waffen-SS were set up. In the last two years of the war several buildings were severely damaged by bombing. During the Battle of Vienna, in the days of 7 to 9 April 1945, was the arsenal, defended by the 3rd SS Panzer Division "Totenkopf", focus of the fighting, the Red Army before their victory recording heavy losses.
History since 1945
Ruins of the object 15 after the air raids 1944
Deposits at the Arsenal Street
After heavy bomb damages during the Second World War, the buildings of the Arsenal were largely restored to their original forms.
In the southern part and in the former courtyard of the arsenal several new buildings were added, among them 1959-1963 the decoration workshops of the Federal Theatre designed by the architects Erich Boltenstern and Robert Weinlich. From 1961 to 1963, the telecommunications central office was built by the architect Fritz Pfeffer. From 1973 to 1975 were built plant and office building of the Post and Telephone Head Office for Vienna, Lower Austria and Burgenland (now Technology Centre Arsenal of Telekom Austria) with the 150-foot radio tower in Vienna Arsenal according to the plans of architect Kurt Eckel. In the 1990s, a rehearsal stage of the castle theater (Burgtheater) was built according to plans by Gustav Peichl.
Also the Austrian Research and Testing Centre Arsenal, now Arsenal Research, which has made itself wordwide a celebrity by one of the largest air chambers (now moved to Floridsdorf - 21st District ), was housed in the complex. A smaller part of the system is still used by the Austrian army as a barracks. Furthermore, the Central Institute for Disinfection of the City of Vienna and the Central Chemical Laboratory of the Federal Monuments Office are housed in the arsenal. The Military History Museum uses multiple objects as depots.
In one part of the area residential buildings were erected. The Arsenal is forming an own, two census tracts encompassing census district, which according to the census in 2001 2.058 inhabitants had.
End of 2003, the arsenal in connection with other properties of the Federal Property Society (BIG - Bundesimmobiliengesellschaft) was sold to a private investor group. Since early 2006, the lawyer of Baden (Lower Austria, not far away from Vienna) Rudolf Fries and industrialist Walter Scherb are majority owners of the 72,000 m2 historic site that they want to refurbish and according to possibility rent new. Fries also plans to enlarge the existing living space by more than half (about 40,000 m2).
An architectural design competition, whose jury on 28 and 29 in June 2007 met, provided proposals amounting to substantial structural changes in the system. Such designed competition winner Hohensinn a futuristic clouds clip modeled after El Lissitzky's cloud bracket, a multi-level horizontal structure on slender stilts over the old stock on the outskirts of the Swiss Garden. The realization of these plans is considered unlikely.
Some objects are since 2013 adapted for use by the Technical University of Vienna: Object 227, the so-called "Panzerhalle" will house laboratories of the Institute for Powertrains and Automotive Technology. In object 221, the "Siemens hall", laboratories of the Institute for Energy Technology and Thermodynamics as well as of the Institute for Manufacturing Technology and High Power Laser Technology are built. In object 214 is besides the Technical Testing and Research Institute (TVFA) also the second expansion stage of the "Vienna Scientific Cluster" housed, of a supercomputer, which was built jointly by the Vienna University of Technology, the University of Vienna and the University of Agricultural Sciences.
Accessibility
The arsenal was historically especially over the Landstraßer Gürtel developed. Today passes southeast in the immediate proximity the Südosttangente called motorway A23 with it connection Gürtel/Landstraßer Hauptstrasse. Southwest of the site runs the Eastern Railway, the new Vienna Central Station closes to the west of the arsenal. Two new bridges over the Eastern Railway, the Arsenal Stay Bridge and the Southern Railway bridge and an underpass as part of Ghegastraße and Alfred- Adler-Straße establish a connection to the on the other side of the railway facilities located Sonnwendviertel in the 10th District, which is being built on the former site of the freight train station Vienna South Station.
On the center side is between Arsenal and Landstraßer Gürtel the former Maria Josefa Park located, now known as Swiss Garden. Here stands at the Arsenalstraße the 21er Haus, a branch of the Austrian Gallery Belvedere, on the center-side edge of the Swiss Garden has the busy suburban main railway route the stop Vienna Quartier Belvedere, next to it the Wiener Linien D (tram) and 69A (bus) run.

Lance Weems and Keith Fitzgerald tend to Dusk, the global parallel file system for Dawn, a 500-teraflop (trillion floating operations per second) supercomputer at Lawrence Livermore National Laboratory. Many of the Lab's supercomputers are used to simulate the conditions inside a nuclear weapon. The computers also are used for earthquake simulations and climate change models.
This is the casino in Valkenburg, The Netherlands. But to me it looks more like an ominous building harbouring a giant supercomputer designed to do something evil. I don't know why, but the place gave me the creeps.

Image: An elevation plot of the highest energy neutron flux distributions from an axial slice of a nuclear reactor core is shown superimposed over the same slice of the underlying geometry. This figure shows the rapid spatial variation in the high energy neutron distribution between within each plate along with the more slowly varying, global distribution. The figure is significant since UNIC allows researchers to capture both of these effects simultaneously.
