Re: [google-appengine] Keep it short: Who is forced to leave GAE?

I've already left GAE a couple of months ago. I.e. immediately after Greg replied to me that new pricing will come into effect before Python 2.7 and multithreading. My app has short bursts of thousands QPS, and without multithreading it was clear to me that for an unknown period I'd have to pay a v

Personally, I'd be much happier to see Node.js supported on GAE, than PHP. Being 100% asynchronous (reactor-type), it would be a great fit for the new per-instance pricing (despite being single-threaded). On Sat, Jun 18, 2011 at 7:47 AM, Ikai Lan (Google) wrote: > Yikes. Those are great points, D

This has the drawback that the user must have a Google Account in order to connect to GTalk. Unfortunately GTalk does not support e.g. SASL ANONYMOUS logins. It would be perfect if the Channel API exposed directly its lower-level XMPP layer. Something like allowing the user to connect via XMPP as

[google-appengine] Channel API future improvements?

Re: [google-appengine] Re: Channel API CPU usage

Hi Nick, Moishe, Specifying the expected channel lifetime at setup time is not very useful - because we _do not_ know in advance how long the user will stay. Some users will stay on the page longer, others will look quickly and go somewhere else. Reusing the channel tokens is not an option for som

It's not necessary to have a build script which explicitly changes the version tag.

Since CURRENT_VERSION_ID is guaranteed to change on every deployment, the version ta

Deploy a third version called 'proxy', make it default, and use it to proxy/distribute the requests to the other two versions (via urlfetch). Two disadvantages: first, urlfetch has 10s time limit, so all your requests will have to complete in 10s; second, you'll consume more resources. On Fri, Nov

Forget about emulating it outside of a browser. Your best bet is using a separate mechanism for sending messages to non-browser clients - for example make a HTTP postback, or send a XMPP message. On Wed, Nov 3, 2010 at 6:20 AM, Robert Kluin wrote: > Have you look at the communications at all? I

[google-appengine] Re: Static resources not updated?

This generally happens when you set a custom expiration time for static files. This causes Google's frontend servers to cache the files for up to the specified time, and they don't update it even if you push a new version in the mean time. This is true both for *.appspot.com and for custom domains.
