I tried using SC2 (aka Amber), while it has a lot of potential and I love the powerful binding mechanism it has, it simply lacked documentation and support. I hope Amber has tackled this issue.

I feel the word rubs you the wrong way and you are trying to come up with arguments to support your emotions.

I would put some effort and change the default bootstrap css theme because it looks like many other websites.

I don't know you and what you say won't give you more credibility. Your points are subjective because they fall under theories. Don't point them out like facts.

All your points are subjective.

I don't like fixed position UI and scrolling within a small section. I prefer the whole page to scroll. I am staying on the old version.

I totally agree that SYSCALL/SYSENTER/SYSRET are very cheap to execute. But these instructions only takes care of the ring switch and are not executed alone. When you make a system call, a trap is issued that causes the hardware switch to k

I didn't say there is no distinction. I said system calls that require disk io, or network io, or triggers locking/sleeping requires a context switch. Calls like read/write/accept triggers context switches (which starts with a mode switch).

by kqueue 15y ago
Network IO, Disk IO, scheduling, locks etc.. all trigger context switches and not only mode switch because only the kernel is allowed to manipulate data structures related to mbufs, vfs, and whatnot. When I said epoll/kqueue doesn't affect

request rate is not influenced much by the polling mechanism (epoll/kqueue/poll/select) when all you're doing is listening to one fd and processing new ones then closing then immediately. These multiplexers matter when you are working on lo

Measuring requests per second is close to measuring the number of accept system calls you can do. Since it's a system call you have a context switch.
15.
by kqueue 15y ago
I believe you are testing the requests / sec and not replies / sec. While requests / sec matters a bit, you'll most probably be bottle-necking in your context switches. What matters is replies / sec. This is a more accurate measurement of y

I see. I haven't tried them personally, my friend has been using them for a year now and so far so good. He did complain about their support though.

This service provider has great pricing compared to softlayer http://www.hetzner.de/en/hosting/produktmatrix/rootserver-pr... Intel Corei7-2600 Quad core + 16GB DDR3 + 2 x 3TB 7200 for 49 euro.

That's why you should start from the finish line and move backwards.

From the polls that happened in the past, I saw more votes in favor of showing scores.

Not to mention that kevent contain the number of bytes to be read, or the number of connections to accept, which can avoid you a system call that returns EAGAIN in a non-blocking socket.

1. Process creation and termination are heavy operations considering that it's being done in a tight loop. 2. You don't want to fork on every request, this is very vulnerable to fork bombs. 3. In worker threads model, you already have the w
23.
by kqueue 15y ago
No that's not the proper way of doing it. You create worker threads in separate process that receive data from node.js, encodes them and send them back. you don't fork on every request.

Ah I missed this. I once tried to implement coroutines in v8 but v8 makes use of getspecific and setspecific pthread methods which makes it more complicated.

by kqueue 15y ago
The proper fix is to introduce coroutines.

You cannot render a pattern useless because you had a bad experience with certain implementations. The pattern represent a very good abstraction concept that is irrelevant to the library implemtation.

Honesty, most are stopping at the fundamentals and not proceeding further. I have yet to see a good JS templating engine that is rich.

by kqueue 15y ago
It's missing namespaces, inheritance, escaping, include tags, or at least that's what I expect from a templating engine
