Canadian here, that’s just not true, you only have to wait if you want to see a specific specialist and they are fully booked, then you have to decide if you would rather wait or see someone else.

Something most people don't know about HoloLens: the holograms stay where you put them indefinitely. So if you put a browser window on a wall in your bedroom and come back after a week, it will be exactly where you left it.

Yes, the holograms are literally objects made of light so at low brightness they are transparent, but if you crank up they will appear solid but you still won't confuse it for a real object because they are so bright. I haven't wa

lol that was the idea, glad you enjoyed it!

Yes it does work outside if the space has enough objects around so it can generate a model of the location. When model generation fails, it falls back to a "limited mode" where holograms follow you around instead of staying where

Here is a video I recorded with HoloLens, but not through it, the actual holograms are transparent on the headset: https://goo.gl/photos/S2B9A8xkvyLkPK7U8

HoloLens user here, based on this video alone, the experience appears to be equivalent, although holograms appear to be a bit more stable on HoloLens, which also has no trouble tracking fast head movements

The problem isn't when you get banned, it is the fact that Google refuses to clearly communicate the reasons when there is real money at stake. Google: "you delivered 30k worth of ads but I don't owe you anything because you

C# is so powerful, expressive and I am glad to see that Mono is becoming more popular and helping to separate C# from the Microsoft stack.

Apple page on ergonomics? How ironic considering that most of their input devices are more like torture devices. Beautiful for sure but suitable for human use.

You are correct, their QC is more of a hardware solver for a very specific problem than a general purpose computer. On scaling, I was a D-Wave a few weeks ago, they seem to be prepared to scale-up the chip aggressively in 2012.
23.
by rfurlan 15y ago
That is not how it works Viscanti, gate-based QCs are still toys and it remains to be proved if they will become useful anytime soon. On the other hand D-Wave's adiabatic chip is very promising but it requires you to fit a "square peg in a

To clarify: you express your problem as an Ising model, load the model into the D-Wave One QC and it will solve it for you. The interesting thing is that solving Ising models is a NP-hard problem. D-Wave's current chip has only 128 qubits a

by rfurlan 15y ago
D-Wave's computer is basically a hardware solver for Ising/QUBO models. It is not programable in the traditional sense and you need to find a way to express the problem you want to solve in a way that maps well over the hardware.

Fsync means "wait for acknowledgement after each request", if Fsync is off, all calls are fire-and-forget, no errors are reported. There are a few Fsync levels though, you can use it to make the call block until the data has been relayed to

Also, I never said SQL Server is slow - it isn't, anyone that would say otherwise must have an agenda, which is not my case. SQL Server is an incredible database and it has served us well.

MongoDB has the potential to be faster than traditional relational databases simply because it does less, way less. The trade off makes sense for some applications, but not for all, it really depends on your requirements.

fsync is enabled for the vast majority of calls and it is our default setting. Disabling fsync should be treated as case-by-case optimization IMO
