When wasn't it faster than Flash? Last time I used Away3D, I had trouble getting more than 5k triangles with a reasonable framerate, which is a bit ridiculous. Admittedly, this was a couple years ago. Has something changed?

I cannot comment for deelowe, but every time in the past I've seen such a wide difference for such a simple benchmark, there was some methodology problem. After all, for such a simple benchmark, most of your time is spent in the OS. It's po

That's why I mentioned "default". If you have more specialized requirements, you can write your own version. :)

How about a few more default data structures, like resizable arrays or hashes? I find the biggest bump in my productivity in most other languages is that those two things are there already.

Upgrading users is one of those "damned if you do, damned if you don't" scenarios. If you do: some users are unhappy about old hardware. If you don't: some users are unhappy about uptime and changing software. Joyent's CEO was on HN a while

I hope Furber updates his ARM book again some day.

Interesting. Thanks. :)

This is specific to the type of filesystem in use. Something like ZFS does not exhibit these artifacts.

Harebrained Schemes (the Shadowrun Returns team on Kickstarter) also uses Moai. Perhaps it's worth a look. Other than the cloud parts, can anyone compare it with Love2D?

You'd likely be better off with multiple processes then. There's no reason to suffer 16 cores performing like three (assuming no contention), when you can get much closer to linear with existing, mature, and well-understood technologies.

This betrays a stark lack of perspective. What's old is often new again, in different guises.

by dmpk2k 15y ago
In theory that sounds great. What I've seen and heard from practice (surprisingly) isn't. I think a better idea is to have excellent communication between the two groups, whether on channels or in the same room. Both specialize, but both ha

Just to be clear to any readers: SmartOS is not meant to be installed on disk, ergo no installer.

illumos is free and (most importantly) open source. Running a closed OS and binaries on a production server isn't the most foolish idea I've heard, but it's in the running.

> less predictable Alas, it is, because there's no communication between the kernel scheduler and the user-space scheduler. The resulting interaction has non-intuitive results. Here's an old paper about some of the measured consequences

In the same vein, LuaJIT2 beta 9 was released a couple days ago.

by dmpk2k 15y ago
I'm not sure it's intrinsic to JIT. LuaJIT's footprint is no larger than the normal Lua VM last I looked. It has more to do with how you pack your data and how much pressure you put on the GC (thus requiring more memory).

I think likewise. It should probably be number of requests per MB of RAM for I/O-bound servers where latency isn't critical.

Having skimmed the article I found it relatively unenlightened. What do you agree with?

With that attitude we should have stopped at FORTRAN. What next, drive a Model T instead of a Civic? Nobody knowledgeable has said that async coding is novel. What matters is that node.js is a simple(r) and effective means of writing asynch

I'm a backend engineer. Have been for years. Node.js works for me. I don't think much else needs to be said.

Sadly, it took me five years of lost time mucking around with every language under the sun to figure this out. Spend a few months to find a reasonable ecosystem (NB: the libraries, tools and community, not just the language), then move on.

The disk problem is maddening, and I used to be a strong proponent of dedicated hardware for this reason. However, the provider I use (Joyent) recently added some kind of disk scheduling that prevents these problems. I don't know how they d

Faster and more efficient than what? They've been saying this every single release since at least as far back as Windows 95. Strangely enough, Windows 3.1 sure seems a lot smaller and snappier than Windows 7...

Some Schemes have this too. I'd be surprised if an industrial VM, like the CLR, didn't support this.

They're not mainstream (that I'm aware of), but there are realtime GCs that can guarantee a pause of less that 1ms. Metronome is the one I'm familiar with.
