Speak for yourself, amigo :-)

While I may be an engineer, I've also been the CTO of a hundred-person
dotcom, and I'm now bootstrapping my own startup.  The dollars I have
spent on this project represent a vastly larger percentage of my net
worth than any VC has probably ever spent on a project.  And I don't
have a portfolio of projects; I can't afford to "lose a few".  I have
far more to lose on a bad technology choice than any VC does.

The "risk minimization" of eschewing appengine for a
build-it-yourself-platform is a false economy; it minimizes the tiny
risk that Google will torch appengine and *greatly* increasing the
risk that the product will never be viable in the first place.

Oh, and True story.  When Windows Server 2003 was in beta I took $150k in

Quicktime, MP4 , and h.264 trasport streams.  All the foundation you needed

[google-appengine] Redirecting to a web page from a servlet

[Tony O Dowd]

I"m calling a httpservlet from a GXT FormPanel using the usual
FormPanel.submit() method. This calls the doPost( request, response)
method of the httpservlet. I"m using Submit as I'm uploading data to
the sever from a client using a FileUploadField in the FormPanel.

My problem is that by using FormPanel.Submit(), the browser opens a
new tab and  jumps to the HTML page of the httpservlet, thus changing
the focus from my GXT main application running in the browser.

anyone know a neat solution to prevent this and maintain the focus in
the main GXT application tab?

Thanks in advance.

[google-appengine] Re: Just a little help

[Tony O Dowd]

Are you using Python or JAVA to build your servlets?

If You're using Java you need to define your servlet in your web.XML
file. You simply define the servlet name, the class it points to and
then the mapping of the servlet name to it's URL. If you checkout the
default web.XML file that is created when you build the default GWT
app in eclipse you'll see a good example of this.

I don't perceive Amazon as playing in the same space with Appengine,
at least not yet.  They're trying with Elastic Beanstalk, SimpleDB,
SQS, etc... but they have a *long* way to go.  I presume they're still
making too much money in the IaaS business to take PaaS seriously.

The way I see it, the future of computing is driven by tools and
environments that let you create a better product with less work.
When the storage, caching, queueing, channel, deployment, and scaling
facilities are all maintained by someone else, your team is massively
more productive.  It's like going from assembler to C.  There is not a
sliver of doubt in my mind that the future of web development looks
something like Google App Engine, and right now there's nobody else
competently playing in that space.  Maybe Azure comes closest if you
are in the .NET camp.

This is interesting, and reinforces my growing belief that VCs are
clueless and all the supposed experience they bring to the table is a
net liability rather than an asset.

There is a massive shift going on right now.  Five years ago it made
sense to try to build giant standalone products.  Today you'd be crazy
not to leverage the hell out of the myriad platform services available
- Facebook, Google, Apple, Netflix, Yelp, and millions of niche APIs.
Like it or not, you either get in bed with them or you produce less
interesting products.

Facebook is the canonical example.  Almost everything about developing
on the Facebook platform is a trainwreck - anemic documentation,
half-baked APIs, forums and bug database are black holes, and the bug
count goes up every week rather than down.  But for any consumer
product, you simply cannot choose not to play the game.

As a small player, I integrate with whatever platforms and services
deliver a better customer experience.  If that makes me a slave to
Google and Facebook, so be it.  Like Zynga, I will just have to learn
to negotiate with the king once I have a big enough mob of angry
pitchforks behind me.  Ask the founders of Wesabe about why they lost
to Mint.  Nevermind, here's their answer:
http://blog.precipice.org/why-wesabe-lost-to-mint  Reason #1 is they
wasted time building their own financial aggregation platform rather
then be beholden to Yodlee.  Mint used Yodlee and spent all those
extra resources on polishing the user experience.

If this is a general VC trend, I think this shows a terrific lack of
experience by VCs.  It dramatically underestimates the difficulty of
building operations infrastructure at "web scale", and how easy it is
to build on platforms like Google and Facebook in comparison.  Which
is not too surprising, because unless you've been hands-on developing

Re: [google-appengine] I need some tips

[Ronoaldo José de Lana Pereira]

Hi Julio,

I guess I know you from Brazil, but I'll write in English. Here is what we 
do for a production Java app:

1) Using flex Json, I added some data fixtures in Json to an app resource 
foder, and created a small servlet that I called SetupServlet. This servlet 
does your trick on checking resultset sizes and populates the database if 
required, and is only called by an app administrator. Very usefull! You can 
combine this with Robert suggestion for an upload-based setup servlet, that 
load the file from Blobstore, for example.

2) To import a really large dataset, like migrating it from one server to 
another, the python remote_api is a great (but slow) tool, because you can 
do some computation to translate a legacy app database to your new 
app-engine optimized version, all on the fly and without the requirement of 
a new build-deploy clicle. But make sure to call db.allocate_id_rage() or 
similar before putting the app alive. I forgot it, and this will cause a lot 
of problems ;). As Robert suggested, bulkloader does most of the job for 
you, and you just need to write some yaml files to map you models fields and 
you can import form a csv file. This is a nice aproach since you can change 
your data remotely, but it will consume your bandwidth quota too.

Regarding your concern about a DOS atack, all requests will be served and 
loged. I tryed on my live app (yes, I'm a bit crazy) and the ammount of 
instances growth from 10~14 to 72 in a few seconds to serve +1000 
simultaneous requests. I also found that my logic was not optimized and that 
helped me a bit! Anyway, that is just all what AppEngine is about: scale as 
you need to support a big access when your app is featured on Yahoo home 
page! What you can do to avoid abuse is monitor your top 10 access and 
optionally blacklist what you fell like a DOS. You can do an appcfg.sh 
upload_blacklist just to make your app blacklist an ip address imedieatly, 
but know what is a DOS, currently, is up to you. You may whant to avoid 
abuse with some tokens, anyway.

Hope it helps!

[google-appengine] Re: How many concurrent channels can GAE handle?

[Jamie]

Thanks for all the responses.

Right now, I'm not re-using channels between clients so I'm
effectively limited to 95K unique hits to my site (which is a lot but
still a limit that *could* be  hit easily if my site made TechCrunch,
Mashable, etc.).  I will look into channel re-use.

But my question was more about concurrent channels.  I'm unclear on
how GAE implements channels, but I assume having many concurrent
persistent connections open would cause performance issues on the
server, so my question was mainly around how many concurrent channels
could GAE handle?

[google-appengine] VCs And Betting The Farm On GAE/Google Technologies Was Startup Weekend and Google App Engine

[Brandon Wirtz]

Jeff, 

 

I may borrow this section for talks with VC's

 

" GAE apps are difficult (not impossible, but difficult) to port because GAE
provides services at a much higher level than IaaS companies.  If you write
to a lower-level platform, you need to invent all those services *yourself*.
This is not without CONSIDERABLE opportunity cost - it takes a lot of work
to run, maintain, and scale datastores, memcaching systems, appservers.  You
need DBAs, you need sysadmins, you need security engineers, you need build
engineers.  It all adds time and cost and risk."

 

Et All, 

 

VCs often talk about "a bet on a bet".  It is my belief that Google will be
a big player in the Cloud space and that part of that will be building out
GAE to compete with Amazon.   I picked GAE specifically because GAE
leverages Google's knowledge of the things they do best, but more
importantly it leverages what Google does better than anyone else.  Rather
than betting that I can hire a team of smart people to manage my
infrastructure, engineer my database, and give me world wide points of
presence I just pay an extra 2 pennies a Gig transferred, and they do it for
me.  That's an easy decision from a cash flow perspective.

 

VCs are Anti-Google right now, so to those saying "does a VC really decline
you funding because you aren't on EC2?" yes.  Google lost a whole lot of
friends with their recent changes to the Openness of Android, and the
conditions of it's use.  There is a fear, founded or not, in the VC
community at the moment that Google will "become Apple" and that they will
only let certain apps play on their network, in their search results, and on
their platforms.  

 

We see this reflected in the recent changes to the rules for Google Search,
Google Adwords, Adsense and Android.  For a VC this is scary.  You may be
right in thinking "there are a million other things scarier than Google
making changes" when calculating the risk to a start up, but for a VC you
look at how many risks there are to failure more than the risk of each of
those things happening, because you can only measure known risks, not
unknown risks.

 

Lastly, is perception.  How much of the chatter on this forum is about if we
should move to HR, or if MS can be made to work.  How much is about if there
is a way to know if some warning light went off at Google when there is down
time?  Do you remember the thread about me saying that if you are going to
switch from one app to another on a domain managed by Apps for Domains, that
you should have a paid account and a CSR on the line when you do it?  Try to
find how to get your Apps For Domains Pin, and how to get someone on the
phone at Google.  I failed to mention that the CSR I talked to doing that
moved didn't know what an "appengine" is and I had to have them find someone
who did.   If you have ever had a Google Docs outage, or if you were one of
the 150k people who had their email disappear 2 months ago in the Great
Gmail Failure of 2011, you can see how people would not trust Google with
their enterprise/mission critical applications.

 

Azure sucks in so many ways, it is more expensive, it has more downtime, and
it doesn't scale up and down as quickly as GAE.  But my projects on Azure
run just as well on a Windows Server farm, and when things go Boom I can get
a live human on the phone in 2 minutes.  If something needs a Kick I can get
it.  No digging through the forums to find out which URL I need to file a
ticket on, no wondering if someone dealt with my ticket, a real person on
the phone says, "I have taken care of that for you Brandon, is there
anything else I can do for you? No? Well we apologize that this happened and
I have issued you a credit for today's services. You have a great day and
thank you for using Microsoft Azure".

 

EC2 is cheaper, if you can get all the products you need set up, and talking
to each other it runs like a champ, and is very portable.  We moved from
Storm On Demand, off to RDS, and then we made a sand box on Storm On Demand
because it was cheaper and we didn't need the redundancy, and then I pushed
the button and moved that sand box to my laptop as a 2 virtual machines.
EC2 Support has a Thick Indian Accent, but they are smart and they do answer
the phone.

 

Ikai, Nick, Wesley, and the rest of the Googlers in this forum are great...
And I'm sure they'd be happy to give us all their personal cell phone
numbers so it would be easy to get problems resolved  But then they'd
get nothing done.  Google's always been in the business of avoiding
technical support by building tech that just works... and that is a Great
philosophy, but it makes people in the investment world crazy, because when
bad things happen they want to know who to blame and when they will be fixed
and how it will never happen again.

[google-appengine] urlfetch - deadline clarification + two issues

[Joshua Bronson]

Hey App Engine Developers,

Regarding the deadline parameter, urlfetch 
docs
 say:

The maximum amount of time to wait for a response from the remote host, as a 
number of seconds. If the remote host does not respond in this amount of 
time, a DownloadError is raised. 


Does this refer to the amount of time the remote host has to simply accept 
the connection, or to transfer the entire response?


I'd also like to call your attention to a couple new issues:

#4878 : if 
you pass allow_truncated=True and the response ends up being truncated, the 
Content-Length header of the returned response is inevitably overwritten 
with 33554432, which is unhelpful since content_was_truncated implies this. 
Would it be possible to stop overwriting this header to reduce information 
loss? My application depends on knowing the total content length of the 
resource in question, even if the urlfetch result is truncated.

#4879 : A 
bug in urlfetch is causing it to generate KeyErrors for some requests.

Thanks for reading!

Josh

Furthermore, if you're using Java and Objectify, you can switch your
data tier over to MongoDB with relatively minor pain.  Scott
Hernandez, who helped out with the original Objectify code, wrote
Mongo's Java ORM system (Morphia) and now works for 10gen.  Morphia is

The problem here is not risk inherent in the platform, but risk
inherent in a team working with an unfamiliar platform.  Your team
could run into similar problems with any platform they aren't familiar
with - especially with the proliferation of new NoSQL stores (remember
Digg?).

The answer to that is the same with any technology platform - the team
needs to be sufficiently familiar with the platform to be able to
competently build the product.  Your startup shouldn't be a spike
solution.  Appengine has been around for years now, there are plenty
of brilliant startup engineers available with deep knowledge of the
behavior and limitations of appengine.  No, not quite as many as
Spring/Hibernate/RDBMS engineers, but this is a startup - you only
need a handful.

Rephrasing this slightly, I can understand if a VC was skeptical about
a handful of traditional web stack engineers with no GAE experience
who want to use appengine.  They should be just as skeptical
(actually, much more so) of a team without RDBMS experience trying to
build a Hibernate app.

1) If you aren't sure your app is appropriate for appengine, you need
to invest in some research time (or hire someone who is familiar with
appengine).

2) Building to a portable API is Planning for Failure.

GAE apps are difficult (not impossible, but difficult) to port because
GAE provides services at a much higher level than IaaS companies.  If
you write to a lower-level platform, you need to invent all those
services *yourself*.  This is not without CONSIDERABLE opportunity
cost - it takes a lot of work to run, maintain, and scale datastores,
memcaching

[google-appengine] RequestError: Server responded with: 500, A temporary internal problem has occurred. Try again later.

[Gwyn Howell]

Am getting this error on a few of my App Engines:

RequestError: Server responded with: 500, A temporary internal problem has 
occurred. Try again later.


Any ideas what is causing this? I notice that there is some scheduled downtime, 
but don't think it is that.

Any help or info would be greatly appreciated.


Thanks

The issue is using a Google Apps account (rather than a Gmail account)
when you create your apps, not what domain they're running on.

Re: [google-appengine] I need some tips

[Júlio Cesar Bueno Cotta]

Hi Robert, I got put the service on with all my fortunes.
I just did that

String query = "select from " + FortunesDAO.class.getName();
fortunes = (List) pm.newQuery(query).execute();
if fortunes.size() == 0
add to DB
else
"Live is good!"
:-D

That is not the best pratice requesting all the fortunes each time the app
run, so with the DB OK, I just remove the verification. :D

I still dont made a client to access the service, but you can access here
http://fortunesweb.appspot.com/fortunesweb?id=1
:-D

Just one thing more..what will happen if someone give me a DOS atack? Google
just turn the service off when my quota become full?
Can someone give me a tip about a way to avoid a massive access to the
service? Add a key?
Thanks for the help!

Re: [google-appengine] Indexes stuck in "Building" state.

[Ikai Lan (Google)]

Moved them into error for you. Go ahead and run vacuum.

In the future, anyone who has stuck indexes should open an issue in the
public issues tracker via the production issues template:

http://code.google.com/p/googleappengine/issues/entry?template=Production%20issue

The
good news is that we're working on a long term fix for index building issues
so these issues should be a thing of a past.

As you can see the exception occurs when executing the next iteration
of the FOR loop (not in the body).  Also, this problem always occurs
after 100 iterations.  Has anyone come across this error?  There
doesn't seem to be much documentation online.

[google-appengine] Just a little help

[Divyahans]

Hi, I'm just starting off with App Engine and was looking for a little
help.

I've made Java Servlets on App Engine with the URLs like -
http://www.test.appspot.com/test

But, how would I make a Java Servlet with the URL - 
http://www.test.appspot.com/test/page2

Could someone give me some advice?

[google-appengine] Sending mail with attachment from GAE

[Nitin Tomer]

Hi,

I am trying to send an email from GAE. To send a text mail without
attachment, I used the following code and it worked like a charm -

String msgBody = "This is another dummy message.";

try
{
Message msg = new MimeMessage(session);
msg.setFrom(new
InternetAddress("ad...@dgobbledygook2.appspotmail.com", "FormHandler
Admin"));
msg.addRecipient(Message.RecipientType.TO,new
InternetAddress("n.to...@gmail.com", "Nitin Tomer"));
msg.setSubject("Test mail to n.to...@gmail.com");
msg.setText(strToPrint);
Transport.send(msg);
}
catch (AddressException e)
{
log.info(e.getMessage());
}
catch (MessagingException e) {
log.info(e.getMessage());
}

Now I want to send a mail with attachment. I copied a PDF file into
the WAR directory of my project and deployed the project. The PDF file
is there at the GAE now, I can access it using the URL. But when I use
the following code to send the mail with attachment, it's not working.
There is no exception/error, but nothing is happeining -

String msgBody = "This is just a dummy message.";

try
{
Message msg = new MimeMessage(session);
msg.setFrom(new
InternetAddress("ad...@dgobbledygook2.appspotmail.com", "FormHandler
Admin"));
msg.addRecipient(Message.RecipientType.TO,new
InternetAddress("n.to...@gmail.com", "Nitin Tomer"));
msg.setSubject("Test mail to n.to...@gmail.com");
//msg.setText(msgBody);

Multipart mp = new MimeMultipart();

MimeBodyPart htmlPart = new MimeBodyPart();
htmlPart.setContent(msgBody, "text/html");
mp.addBodyPart(htmlPart);

// Read file

File file = new File("TestForm.pdf");
byte fileContent[] = null;

try
{
FileInputStream fin = new FileInputStream(file);

/*
 * Create byte array large enough to hold the content of
the file.
 * Use File.length to determine size of the file in
bytes.
 */

fileContent = new byte[(int)file.length()];

/*
 * To read content of the file in byte array, use
 * int read(byte[] byteArray) method of java
FileInputStream class.
 *
 */

fin.read(fileContent);
}
catch(FileNotFoundException e)
{
e.printStackTrace();
}
catch(IOException ioe)
{
ioe.printStackTrace();
}

MimeBodyPart attachment = new MimeBodyPart();
attachment.setFileName("manual.pdf");
attachment.setContent(fileContent, "application/pdf");
mp.addBodyPart(attachment);

msg.setContent(mp);
Transport.send(msg);
}
catch (AddressException e)
{
log.info(e.getMessage());
}
catch (MessagingException e) {
log.info(e.getMessage());
}

Please tell me what I am doing wrong, and how can I make it work.

Thanks and Regards

Nitin

[google-appengine] SSL access on non-appspot.com domains

[Vikram]

Hi,

I was wondering if Google App Engine will shortly provide SSL access
on non-appspot.com domains for an account that is non-business (i.e.
free). I do see this as a high priority item on the GAE roadmap here -
http://code.google.com/appengine/docs/roadmap.html. I also did read a
recent announcement that this feature is already present in App Engine
for business. So, will this be introduced in the free version of GAE?

Regards,
Vikram

[google-appengine] Need design advice - Application Licensing Problem

[Wayne]

 

What is the best way to design a GAE application so that I can: 

   - Have the customer account setup between my customer and Google 
   - Protect my source code from customer access or viewing
   - Shut off access if the customer is behind in paying a license fee. 
   
I am developing an application that will let individual truck transportation 
brokers control the tracking and billing of their client’s shipments.   I 
would like to use Google App Engine for the front and back ends. 

For security reasons, I am assuming that each of my customers would need a 
separate Google App Engine account.

I would also like to have the customer’s account setup directly with Google 
to keep me out of any billing and payment issues.

I am planning to license, to my customers, my application that would run in 
their account.  I need some way to turn off the application if are not 
current with the license fee. 

Naturally, I need some way to protect my code running on the customer 
account from viewing or access. 

Can anyone tell me how to do this?  Or, can anyone recommend a better way to 
handle these issues? 

Thanks in advance for your help. 

Wayne

[google-appengine] Re: Can't list or remove applications

[Dale E]

I'm having a similar problem. From

https://www.google.com/accounts/b/0/ManageAccount

When I click on "My Applications" I'm taken to

https://appengine.google.com/start

Even though I've already used that form to create 2 apps. Clicking on
the dashboard on the Google App Engine Launcher yields the same
result.

[google-appengine] BadRequestError: query not found (occurring in the middle of a for loop)

[Raj Arasu]

Hello,

I am currently having issues with the error BadRequestError: query not
found.  I am using the django framework with norel.  Here is the
context in which the error occurs:
  1. query for all users -> People.objects.all()
  2. loop through all these users and perform some action on them

Everything performs as expected up until the loop reaches the 101th
person. At this point I receive the above mentioned error.  I tested
this through the remote shell and while it did work, I saw brief
moments of pause after each 100 people were looped through.  For
example, there were pauses at 100, 200, 300 and so on. Also, to be
clear there are only 450 people in this datastore kind.

I not sure if there is a timeout issue, if GAE is querying in 100
record blocks...

If anyone can offer any insight that would be great.

Thanks,

Raj

[google-appengine] i18N pyramid on Google App Engine

[Jamil Atta Junior]

Hi,

I new in GAE with Pyramid, I try to use the i18N on this, but have
some problem to set on GAE the initial data for my application on
Pyramid, on Pyramid we have the development.ini and production.ini
files, but GAE don't read this file and my application need some param
around i18N.

My question is: how to set the initial data on Pyramid using GAE?

thanks,

Jamil Atta Junior

It's certainly not impossible to port datastore code to some other NoSQL DB.
The most important GAE-specific feature that isn't easily transferable is
transaction support, but even that can be dealt with in various ways (in the
worst case you build a SQL-based sharded solution). You can also simplify
the porting process a lot by using Django-nonrel. You might think that this
is a risk in itself, but any team worth investing in should be capable of
maintaining their own Django-nonrel fork (yes, the code is very simple) in
the unlikely case of us abandoning Django-nonrel.

If a product relies heavily on datastore writes then App Engine might not be
the best choice to start with (writes are not only expensive, but also very
slow). In this case I can understand if VCs have doubts about the
technology. However, a lot of other web businesses fit App Engine's model
very well. Such businesses also don't react too sensitively to GAE's pricing
changes and even if GAE becomes a major cost factor you can still move away.

I'm not sure why you'd want to run a 50GB datastore on your laptop. :) If
you're forced to move away from GAE you can port your code to e.g. MongoDB
or Cassandra (again, Django-nonrel makes this relatively easy) and then you
can put those 50GB on your (e.g. EC2-based) MongoDB/Cassandra cluster.
Where's the problem, really?

I am a HUGE proponent of GAE, and I'm betting the farm on it, but as an

Since when do VCs (esp. "any VC") always make the right decisions? Most
importantly, since when do VCs make good technological decisions? FYI, I
don't have anything against VCs in general. I just think that a VC who
declines an investment solely because it's a GAE-powered startup probably
would've ended up being your worst nightmare, anyway. Actually, if I told
such a VC "now we'll build it on EC2, are you in?" I'd find it hard to
believe that he would say "yes, now everything is perfect!". That's
ridiculous. Probably this "no GAE" stuff is just an easy excuse, so they
don't have to tell you straight in your face: "we don't believe in your
product/market/team/whatever".
