Hoy en día, no puedes dejar a un lado los puntos de reunión para convivir con amigos o familiares y decir la siguiente frase “vamos a un cafesito”,donde aparte de tomar esta bebida calentita o fría y de sabores diferentes.Hay algunos que cuentan con variedad de repostería como galletas, pasteles,etc;También el tener acceso a libros , revistas o a algunos juegos de mesa y kareoke.

En la decoración cada uno tiene su estilo que los diferencia ,pero todos cuentan con sillones, mesas y sillas afuera.

En su mayoria estan localizados entre edificios o centros comerciales importantes,en realidad en lugares centricos y estratejicos de Tijuana.

Pero  el que te mencionaré es diferente, comenzando por el nombre Café Latitud 32°. Como todos sabemos, latitud es la medida geográfica que estima el ángulo entre cualquier punto y el Ecuador. En el caso de Tijuana, se ubica dentro de los paralelos 32° 31' 30" de latitud norte y a 117° de longitud; aquí, en este lado del Trópico de Cáncer,mientras te vas acercando al malecón de Playas de Tijuana.

Según el semanario Bitacora cultural, en una entrevista a el dueño Carlos Ceseña no sabía que se convertiría en “atrapador de recuerdos” cuando planeó abrir este café a la orilla de la playa en 2001

Como buen tijuanense eligió Playas de Tijuana como una opción muy agradable para montar su café. De hecho, comenta que fue una selección que se dio de manera natural, casi sin planearlo. Y poco a poco este espacio se tornó en un punto de referencia ideal para todo aquel que quisiera un buen café, chocolate, té, latte o comida fría. Al mismo tiempo que abría el parteaguas para pasar esos largos domingos tijuanenses en los que de pronto se limitaban las posibilidades de diversión; y apareció entonces como ante los náufragos, como un salvavidas sin precedentes para muchos artistas plásticos, músicos, cineastas, escritores y demás; que encontraron un hilo tendido al muelle de la difusión de su obra, a la posibilidad de expresarse abiertamente.

Este lugar es mágico, todos los domingos en la noche se convierte en uno de los mejores escenarios que pueden verse en nuestra ciudad.donde la noche toma el sonido al retumbar las olas de el mar y ritmo con el djambae.

La decoración esta basada en el tema, etnico,una forma natural ,ya que cuenta con figuras hechas de madera;la iluminación es a base de velas o bombillas de gas (como en la antiguedad).cuenta con un sillón y frente a el una chimenea, que adorna con un candelabro y ahí es el espacio para hacer sonar el conjunto de ritmos de las congas,djambae y percusiones.

Aquí no importa tu estatus social sino que te dejes llevar con el sonido y lo que te comunican al demostrarte el amor al arte.Nadie te hara mala cara, ahí puedes acercarte y tocar uno de estos instrumentos y ponerte a bailar y nadie te criticara .

Lo que resalta mucho aquí, es la convivencia que se puede lograr y lo impresionante es que no lo hacen por cobrar si no para compartir lo que saben y sienten.

Este es uno de los lados buenos que tiene Tijuana ,que aun existe el contacto con la naturaleza y donde la música es espontánea, resaltar que la vibra es diferente.porque aquí hay hernandad que es lo que nos falta recalcar y se cierra hasta el ultimo que se va.

"Wovon leben wir? -

Zwischen Flexibilität und Prekariat"

bei Freiem Eintritt im ORF RadioKulturhaus statt.

Flexibilisierung von Arbeitsverhältnissen, Vollzeitbeschäftigung als rares Gut, "Generation Praktikum" und "Working Poor":
Das nächste "ORF-DialogForum" widmet sich im Rahmen des "Ö1 Dossier: Arbeit" in Kooperation mit der Ö1-Wissenschaftsredaktion am Montag, dem 28. April 2008, unter dem Titel "Und wovon leben Sie?" dem für die Menschen und die moderne Gesellschaft immer wichtiger werdenden Thema Arbeit.

Viele suchen Sicherheit, propagiert aber wird Arbeit in Projekten. Gemeint ist damit oft sogenanntes prekäres Arbeiten. Selbstständigkeit eröffnet aber auch neue Freiheiten und Berufsfelder. Welches Mindestmaß an Sicherheit und Einkommen ist für produktive Arbeit nötig?

Unter der Leitung von Wolfgang Ritschl diskutieren im ORF KulturCafe die Wirtschaftsforscher und Arbeitsmarktexperten Jörg Flecker (Wissenschaftlicher Leiter von FORBA), Michael Meyer (Vorstand des Instituts für Organisation und Verhalten in Organisationen an der Wirtschaftsuniversität Wien), Andrea Schober (Interessengemeinschaft work@flex in der Gewerkschaft der Privatangestellten-DJP), Anna Schopf (Mitbegründerin der Internet-Plattform generation-praktikum) und Peter Zellmann (Leiter des Instituts für Freizeit- und Tourismusforschung).

Eine Zusammenfassung der Diskussion ist in den "Dimensionen" am 29. April 2008 ab 19.05 Uhr in Ö1 zu hören.

Among the dozens of bottle-conditioned brews on offer was Otley 01 from Pontypridd, south Wales, a town I lived in for a short while.

I remember the Otley Arms (who make the beer) in Trefforest fondly, especially the barman (who was as nice as pie as long as he didn't eat anything before he drank) and the landlord's daughter, who snagged the most attractive, interesting man in the village on the offer of free, good ale as much as her good heart.

Since 2002, long after I'd gone, they started producing their own beer and, on the strength of this sample, have a very bright future.

The beer is straw-coloured pale ale with good fruity nose.

It poured surprisingly flat, almost like a northern pint with no sparkler, but on first sip there was exciting peach flavours turning to quince or perhaps even tangerine, before a pleasant, almost palette-clearing watery sensation in the mouth, ending with a biscuit finish.

It's a first-class ale, highly recommended. And I'm not the only one who thinks so, the lovely, Amazonian woman from Lancashire Heroes told me it was flying off the shelf.

Update 10.3.2008: Inflationsopfer bei Google: 272 Treffer!

Total time taken to automatically assign seats in 128 sample table plans varying in size from 0 to 1500 guests

The chart shows that the new version automatically assigns seats more than 5 times faster over a wide range of table plans. The median improvement in speed is 66%, but the largest plans were solved over ten times faster. How did I do it? Mostly by straightening out a few kinks.

Some years ago I purchased my first dishwasher. I was really excited about being freed from the unspeakable tyranny of having to wash dishes by hand (bear with me). I installed it myself - how hard could it be? It took 10 hours to do a wash cycle. Convinced that the dishwasher was faulty I called the manufacturer. They sent out an engineer who quickly spotted that I had kinked the water inlet pipe as I had pushed the dishwasher into place. It was taking at least 9 hours to get enough water to start the cycle. Oops. As soon as the kink was straightened it worked perfectly, completing a cycle in less than an hour. Speeding up software is rather similar - you just need to straighten out the kinks. The trick is knowing where the kinks are. Experience has taught me that it is pretty much impossible to guess where the performance bottlenecks are in any non-trivial piece of software. You have to measure it using a profiler.

Unfortunately Visual Studio 2005 Standard doesn't seem to include profiling tools. You have to pay for one of the more expensive versions of Visual Studio to get a profiler. This seems rather mean. But then again I was given a copy of VS2005 Standard for free by some nice Microsofties - after I had spent 10 minutes berating them on the awfulness of their "works with vista" program (shudder). So I used an evaluation version of LTProf. LTProf samples your running application a number of times per second, works out which line and function is being executed and uses this to build up a picture of where the program is spending most time.

After a bit of digging through the results I was able to identify a few kinks. Embarrassingly one of them was that the automatic seat assignment was reading a value from the Windows registry in a tight inner loop. Reading from the registry is very slow compared to reading from memory. Because the registry access was buried a few levels deep in function calls it wasn't obvious that this was occurring. It was trivial to fix once identified. Another problem was that some intermediate values were being continually recalculated, even though none of the input values had changed. Again this was fairly trivial to fix. I also found that one part of the seat assignment genetic algorithm took time proportional to the square of the number of guests ( O(n^2) ). After quite a bit of work I was able to reduce this to a time linearly proportional to the number of guests (O(n) ). This led to big speed improvements for larger table plans. I didn't attempt any further optimisation as I felt was getting into diminishing returns. I also straightened out some kinks in reading and writing files, redrawing seating charts and exporting data. The end result is that the new version of PerfectTablePlan is now much more usable for plans with 1000+ guests.

I was favourably impressed with LTProf and will probably buy a copy next time I need to do some optimisation. At $49.95 it is very cheap compared to many other profilers (Intel VTune is $699). LTProf was relatively simple to use and interpret, but it did have quirks. In particular, it showed some impossible call trees (showing X called by Y, where this wasn't possible). This may have been an artefect of the sampling approach taken. I will probably also have a look at the free MacOSX Shark profiler at some point.

I also tried tweaking compiler settings to see how much difference this made. Results are shown below. You can see that there is a marked difference with and without compiler optimisation, and a noticeable difference between the -O1 and -O2 optimisations (the smaller the bar, the better, obviously):

Effect of VS2005 compiler optimisation on automatic seating assignment run time

Obviously the results might be quite different for your own application, depending on the types of calculations you are doing. My genetic algorithm is requires large amounts of integer arithmetic and list traversal and manipulation.

The difference in executable sizes due to optimisation is small:

I tried the two other optimisation flags in addition to -O2.

• /OPT:NOWIN98 - section alignment does not have to be optimal for Windows 98.
• /GL - turns on global optimisation (e.g. across source files, instead of just within source files).

Neither made much noticeable difference:

However it should be noted that most of the genetic algorithm is compiled in a single file already, so perhaps /GL couldn't be expected to add much. I compared VC++6 and VS2005 version of the same program and found that VS2005 was significantly faster[1]:

I also compared GCC compiler optimisation for the MacOSX version. Compared with VS2005 GCC has a more noticeable difference between optimised and unoptimised, but a smaller difference between the different optimisations:

Surprisingly -O3 was slower than -O2. Again the effect of optimisation on executable size is small.

I also tested the relative speeds of my 3 main development machines[2]:

It is interesting to note that the XP box runs the seat assignment at near 100% CPU utilisation, but the Vista box never goes above 50% CPU utilisation. This is because the Vista box is a dual core, but my the seat assignment is currently only single threaded. I will probably add multi-threading in a future version to improve the CPU utilisation on multi-core machines.

In conclusion:

• Don't assume, measure. Use a profiler to find out where your application is spending all its time. It almost certainly won't be where you expected.
• Get the algorithm right. This can make orders of magnitude difference to the runtime.
• Compiler optimisation is worth doing, perhaps giving a 2-4 times speed improvement over an application built without compiler optimisation. It probably isn't worth spending too much time tweaking compiler settings though.
• Don't let a software engineer fit your dishwasher.
