- That's not a VR glass. It's AR. They are completely different. For full VR, the display must be completely opaque. The side must be sealed to block environment. It's impossible to make it with a normal glasses shape with current tech and I don't think we can make it in a near future.
- But we still don't have such a display tech or do we? I've never heard something like that. Probably someone can invent such tech within a decade. But seeing it in a consumer product takes time. So it's safe to assume that it won't happened within a decade if we don't even have such tech today. Especially in this context of investment.
- I'm very skeptical about that. We don't even have the technology for such display can be implemented on transparent glass. Also we don't have that good battery tech which can drive such gear and smaller enough to be hidden in a glasses.
Even if we have all of those tech today, it will take long time to make it a mass production. IMH it will take at least decades to get that level.
- Even the performance benefits are not big enough compare to the GIL.
Biggest problem of the process model might be the cost of having too many DB connections. Each client need a dedicated server process. Memory usage and the context switching overhead. Or if there is no connection pool, connection time overhead is very high.
This problem has been well addressed with a connection pool. Or having a middle ware instead of exposing the DB directly. That works very well so far.
Oracle has been supporting the thread based model and it's been usable for decades. I remember I tried the thread based configuration option (MTS or shared server) in 1990s. But no one likes that at least within my Oracle DBA network.
It would be a great research project but it would be a big problem if the community pushs this too early.
- It's all about trade off.
Building a database which is never gonna crash might be possible but at what cost? Can you name any single real world system archived that? Also, there can be a regression. More tests? Sure but again, at what cost?
While we are trying to get there, having a crash proof architecture is also a very practical approach.
- I'm not sure what you mean by OS. If you mean a whole new kernel, it will take decades. They can support only small number of HW. If you mean a specialized linux distro, many companies does that already.
I don't know how that can make it easier the process based / thread based problem.
- That will make my eye super tired. Just looking at a word doesn't need much effort but focus on very precise location in between two character is very different. Try it with for example iiiiiiiiiiiiiiiiiiii or |||||||||||.
Actually, the presence of a cursor makes it much easier. Place a cursor and looking at it vs Place the cursor by looking at a place are very different.
- It does look like a Ponzi. Aren't there any regulations to prevent that?
It's pretty similar to Korea until the step 3 but we have some safeguards after that.
Instead of giving money directly to the development corp, we give it to a trust corp. And the dev corps can only use the money to build the building.
And if the dev can not meet the due date and if it is delayed more than 3 months, the contract can be cancelled and the owners can get the money back.
That very rarely happens because dev corps desperately meet the deadline regardless of the quality. That causes hell lot of another issues but that's totally different story.
It seems to me like there are many things missing in the Chinese real estate system. Or is it just because no one cares the regulations?
