What Is Portablism? 2016 Is The Year Of The Portable Turntable DJ

If there’s one big new trend in the DJ world in 2016, it has been the rise of portablism. This is the art of cutting and scratching with portable turntables. The use of easily transportable gear means that portablists can perform almost anywhere they want, often leaving DJ booths and nightclubs for more exciting locations. See portablism in action and learn the tools of the trade in today’s article.

The header image is a screenshot from this YouTube video, “Skratcher TV”, featuring in-car scratching from Wundrkut, Mike MSA & Paul Skratch. 

Portabalism In Action

There’s a movement that’s bringing turntablism out of the darkness – literally – and into daylight settings. Busking with 45s or cutting it up in a car with your friends are great ways to practice fader skills in a lower pressure environment than when playing a gig.

Portablism is the practice of DJing (most commonly in a turntablism-style fashion) with easily transportable gear.

Portablism has become possible because of a unique type of product that has appeared in the last two years: pocket / portable faders (more on these below). They allow DJs to have crossfader control over audio without any other controls. No mixer needed.

It’s the natural follow-up to turntablism and controllerism, but with a specific focus on enjoying the creative adventure of practicing a craft in a new and unique places. A great example is in the above new video via DJ City (part of the cleverly-named “Off The Beat and Path” series).

But not every portablist set is a huge production with drones and gasoline generators. Sessions are more often shared on Instagram, which lends itself to more on-the-fly videos of performers:

Portablist Tools Of The Trade

What makes portablism different from turntablism is the type of gear used. You can’t lug a heavy Technics SL-1200 in your backpack, and a full-sized mixer is unnecessary for most.

Here’s the gear that we’ve seen used (this list might not be complete, so feel free to share your additions in the article comments):

  • Portable Turntables: They weigh much less than any typical DJ turntable, are battery-powered, and usually belt-driven. The most common ones used by portablists are the Vestax Handy Trax (~$ 350, discontinued but are still sold online) and the Numark PT01USB ($ 99). Older retro gear also can work well – like the below Columbia GP-3:
  • Pocket Faders: These are the devices that have made portablism possible. Before pocket faders, there wasn’t a truly portable solution for cutting audio in and out on the fly. The first one we saw on the market was the Frisk Fader, which simply cut audio in and out from a single source with two 1/8″ jacks – one for the input and one for the output.There are a few other competitors out now, including the Raiden Fader, Jesse Dean’s JDDX2R, and even the wireless Mixfader (a Bluetooth option for use with an iPhone app). Watch the Raiden Fader VVT-MK1 in the video below:

Many portablists will mount their crossfader directly on their turntable with heavy-duty adhesive. DJ Woody came up with an even crazier idea – a mount for the pitch fader:

  • Scratch Records: These are already a tool of the trade in the turntablism world, but often portablists will want 7″ records to cut with instead of full-sized 12″ records. In recent years, a lot more of these have popped up. Check out some from Texas Scratch League, Richie Ruftone, and of course Qbert’s Thud Rumble.Watch Richie cut it up on his own 7″ release below:

What do you think the future of portablism could look like?

Hidden Secrets: Investigation Shows That NVIDIA GPUs Implement Tile Based Rasterization for Greater Efficiency

As someone who analyzes GPUs for a living, one of the more vexing things in my life has been NVIDIA’s Maxwell architecture. The company’s 28nm refresh offered a huge performance-per-watt increase for only a modest die size increase, essentially allowing NVIDIA to offer a full generation’s performance improvement without a corresponding manufacturing improvement. We’ve had architectural updates on the same node before, but never anything quite like Maxwell.

The vexing aspect to me has been that while NVIDIA shared some details about how they improved Maxwell’s efficiency over Kepler, they have never disclosed all of the major improvements under the hood. We know, for example, that Maxwell implemented a significantly altered SM structure that was easier to reach peak utilization on, and thanks to its partitioning wasted much less power on interconnects. We also know that NVIDIA significantly increased the L2 cache size and did a number of low-level (transistor level) optimizations to the design. But NVIDIA has also held back information – the technical advantages that are their secret sauce – so I’ve never had a complete picture of how Maxwell compares to Kepler.

For a while now, a number of people have suspected that one of the ingredients of that secret sauce was that NVIDIA had applied some mobile power efficiency technologies to Maxwell. It was, after all, their original mobile-first GPU architecture, and now we have some data to back that up. Friend of AnandTech and all around tech guru David Kanter of Real World Tech has gone digging through Maxwell/Pascal, and in an article & video published this morning, he outlines how he has uncovered very convincing evidence that NVIDIA implemented a tile based rendering system with Maxwell.

In short, by playing around with some DirectX code specifically designed to look at triangle rasterization, he has come up with some solid evidence that NVIDIA’s handling of tringles has significantly changed since Kepler, and that their current method of triangle handling is consistent with a tile based renderer.


NVIDIA Maxwell Architecture Rasterization Tiling Pattern (Image Courtesy: Real World Tech)

Tile based rendering is something we’ve seen for some time in the mobile space, with both Imagination PowerVR and ARM Mali implementing it. The significance of tiling is that by splitting a scene up into tiles, tiles can be rasterized piece by piece by the GPU almost entirely on die, as opposed to the more memory (and power) intensive process of rasterizing the entire frame at once via immediate mode rendering. The trade-off with tiling, and why it’s a bit surprising to see it here, is that the PC legacy is immediate mode rendering, and this is still how most applications expect PC GPUs to work. So to implement tile based rasterization on Maxwell means that NVIDIA has found a practical means to overcome the drawbacks of the method and the potential compatibility issues.

In any case, Real Word Tech’s article goes into greater detail about what’s going on, so I won’t spoil it further. But with this information in hand, we now have a more complete picture of how Maxwell (and Pascal) work, and consequently how NVIDIA was able to improve over Kepler by so much. Finally, at this point in time Real World Tech believes that NVIDIA is the only PC GPU manufacturer to use tile based rasterization, which also helps to explain some of NVIDIA’s current advantages over Intel’s and AMD’s GPU architectures, and gives us an idea of what we may see them do in the future.

Le rinnovabili, seconda fonte di elettricità nel mondo

Prosegue la crescita dell’energia verde secondo le ultime statistiche diffuse dall’International Energy Agency. Boom di eolico e fotovoltaico, anche se le biomasse solide e l’idroelettrico restano le risorse rinnovabili più utilizzate a livello internazionale, soprattutto in Africa e Asia. I dati sui paesi OCSE.

Continua a crescere la percentuale di energia generata con fonti rinnovabili a livello mondiale, soprattutto nel settore elettrico, mentre in altri comparti – ad esempio i trasporti – le fonti fossili sono più difficili da scalfire.

Secondo gli ultimi dati pubblicati dall’Agenzia Internazionale dell’Energia (IEA), infatti, si vede che le rinnovabili, nel 2014, coprivano il 13,8% delle forniture globali di energia primaria, grazie soprattutto all’apporto di biofuel e biomasse solide, come la legna da ardere ampiamente sfruttata in vaste zone rurali dell’Africa e dell’Asia (grafico sotto).

Dal 1990 in poi, prosegue l’analisi della IEA, la produzione energetica delle rinnovabili è aumentata in media del 2,2% l’anno con due impennate: fotovoltaico +46% ed eolico +24%, mentre tutte le altre tecnologie non sono andate oltre il +13% registrato dal biogas. Il boom degli impianti eolici e solari si è verificato in particolare nei Paesi OECD e in Cina.

Tuttavia, l’idroelettrico e le biomasse solide, nel 2014, erano ancora le risorse rinnovabili più utilizzate nel mondo. Tanto che quasi metà dell’energia consumata in Africa, e circa un quarto di quella consumata in Asia (Cina esclusa) è classificata come rinnovabile, anche se a ben vedere si tratta di biomasse legnose bruciate nelle abitazioni per cucinare o riscaldare gli ambienti.

Nelle economie più industrializzate, al contrario, la quota delle rinnovabili scende al 10% circa, proprio perché nei Paesi OCSE queste forme arcaiche e poco efficienti di riscaldamento domestico/cottura dei cibi sono assai poco diffuse.

Le rinnovabili in campo elettrico

Guardando ora al solo settore elettrico (grafico sotto) si nota immediatamente che le rinnovabili sono diventate la seconda fonte di generazione, battute soltanto dal carbone, che due anni fa produceva il 40% dell’intera elettricità mondiale.

L’output delle tecnologie pulite si attestava intorno al 22% del totale, davanti al gas (21,6%) e al nucleare (10,6%).

In questa torta del mix di produzione, la fetta delle rinnovabili è dominata dall’idroelettrico, che da solo ha fornito il 73% abbondante di tutta l’elettricità verde; le altre risorse, quindi eolico, solare, geotermia, eccetera, si sono fermate al 18% del green mix, con la parte rimanente (1,8%) coperta da biomasse e recupero energetico dai rifiuti.

Infine, concentrando l’attenzione sull’area OCSE, si osserva che la produzione elettrica delle rinnovabili è aumentata del 3,8% dal 2014 al 2015, raggiungendo 2.471 TWh, pari al 23% dell’output complessivo, che è il livello più alto mai registrato fino a quel momento.

Nel periodo 1990-2015, sempre nei Paesi OCSE, la singola fonte rinnovabile a essere cresciuta maggiormente in termini percentuali è stata il fotovoltaico, +44% in media ogni anno, anche se nel 2015 produceva ancora circa 7% dell’energia elettrica verde complessiva. L’eolico, di contro, generava quasi il 23% dell’elettricità da fonti rinnovabili.
