[google-appengine] addFilter deprecated. How to replace it?
Hello, I just updated my SDK and found out that some methods I used before are deprecated now. How do I change something like ListWriteEntry entries = null; Query q2 = new Query(hiscoretable); q2.addFilter(theID, FilterOperator.EQUAL, id); q2.addFilter(ip, FilterOperator.EQUAL, myIP); q2.addFilter(timestampy,FilterOperator.GREATER_THAN_OR_EQUAL,timeDelay); so it is alright again?

RE: [appengine-java] Billed CPU time by far too high
Hi Ikai, it's also possible that you were being *underbilled* previously and that we've corrected billing information. that is quite interesting. Google just can decide that someone is underbilled so he/she has to pay an extra 700% on CPU time. So not everyone has to pay the same for the same good. I think that this is quite ridiculous. Probably it does not make sense to invest in this platform anymore but better develop my software on another cloud service like Amazon.

I'd advise running AppStats to profile where all the additional CPU usage is coming from. This information would be extremely helpful both to you as well as to other developers who may experience the same issues. Without knowing additional information, it's also possible that you were being *underbilled* previously and that we've corrected billing information.

[appengine-java] More errors every day
Hi, I had yesterday the following error more than 60 times: Request was aborted after waiting too long to attempt to service your request. This may happen sporadically when the App Engine serving cluster is under unexpectedly high or uneven load. If you see this message frequently, please contact the App Engine team. Does this consume so much CPU time? I can't tolerate it if my webapp does nothing all day long and I am billed 1 hour of CPU time.

[appengine-java] Hebrew Chat on App Engine
Hello my dears, I published today my first application run on Google App Engine. Backend is Java, de-/serialization GraniteDS, frontend Flex/Flash. It is totally free. To use it you just have to create a new account on- site. It is a state-of-the-art chat designed to be used by Hebrew students and study groups to communicate easily with each other live in English/ Hebrew. Writing in Hebrew is very easy thanks to the fully integrated virtual keyboard that can be customized in many ways. Full niqqud is supported. Everyone can create chat rooms. A room can optionally be password protected to restrict the access. It is a great tool for study groups to meet on a regular basis to practice Hebrew online together.

I have the same problem, but it is not about the favicon.
It is about getting app engine to send through smtp.googlemail.com an
email.
Is this possible ?
Are these props ever considered by Transport.send ??
props.put(mail.smtp.host,smtp.gmail.com);
props.put(mail.smtp.username,sowji.apr10);
props.put(mail.smtp.PASSWORD,smtp.gmail.com);
My app only sends emails if I use setFrom(*) inserting an app admin,
developer or a some...@myapp.appspot.com address.
Best regards,

[appengine-java] Re: Google App Engine : web-app being hibernated ?
Hi, do you know the exact time ? I noticed too that sometimes a request can take up to 20 seconds. I am using for the front-end flash/flex which allows me to request a status information every 15 seconds (at the moment). I already needed this status info for proprietary session handling and the so-called maintenance shut down. After the first request which can take a lot of time, everything goes smooth. I wonder at what time intervals I should set my alive handler. The first idea was about 3 minutes but that is maybe too slow.

In the doc there it is said that only addresses of admins or developers are valid. I tried to create a new developer m...@mydomain.com but that does not work (no invitation email ever arrives). If I send an email from hotmail to m...@mydomain.com it arrives. What can I do ? I have a registration form and the password should be sent to the user by email.

[google-appengine] Performance: Datastore writes vs. logging writes
We want to collect usage statistics with our app. Therefore, we want to track user actions somewhere on the server side. Which option is more suitable, performance-wise: 1. Track user actions in the App Engine Log, i.e. write a log entry each time. Evaluate the logs for usage statistics. 2. Track user actions in a table in the Datastore. Write an entry for each user action. Evaluate this table for usage statistics. I would guess, that log writes are much faster than Datastore writes. What are your experiences and suggestions?

Thanks, Datastore is safer and easier to handle for datamining that is for sure. But as this information is not critical, I worry more about performance. Memcache is probably fastest but also most complicated. So how do these three methods compare in terms of performance? Is it - Memcache: 1ms - Request Log: 10ms - Data Store: 50ms Or something else?

[google-appengine] Wishlist for App Engine
Hi, we are using the App Engine for our application for some time now. I would like to list our most pressing feature wishes for a future version of the App Engine here: 1. Data import / export tool - A simple CSV import/export tool would be sufficient for us, provided it can import and export data with references between tables. 2. HTTPS support - As our application transfers private data, HTTPS would really help us. Currently we have to implement data encryption on our own. 3. Java support - As our application grows, we feel Java would much better suit us. Especially we miss the great IDE support of Java which allows us to refactor much more efficient. Plus, the rest of our application is Java, so we won't have to write our code in two languages. 4. Unlimited Application quota with payment model - Currently we do not exceed the application quota, but this might happen very soon. So we are really longing for an unlimited application quota (where we pay if we exceed the free quota). Maybe other App Engine users would like to post their most pressing wishes here too.
