Android Cloud Printing with No Dialogs

由 只谈情不闲聊 提交于 2019-12-04 23:46:09
I'm developing a kiosk type Android app and would like to add printing capability. Since it's a kiosk app, the less prompts/pop-ups the users have to do, the better. I was able to get the new Google Cloud Printing successfully going in my Android app but there are a few screens the users need to go through before printing can happen. I was wondering if anyone has any ideas on how to have things print automatically with no dialogs, the idea would be to pass whatever user selections are needed (paper size, orientation, etc) from preferences. Exact same problem we have! Silently printing without

由 心已入冬 提交于 2019-12-04 20:24:02
问题 What are the differences between private cloud and public cloud ? Please define both and giving examples with usage. 回答1: A public cloud is offered as a service via web applications/web services( usually over an Internet connection). Private cloud and internal cloud are deployed inside the firewall and managed by the user organization. There is another type of cloud, hybrid cloud.

What are the typical uses cases for LXC versus VM?

由 故事扮演 提交于 2019-12-04 20:22:02
问题 I am trying to make up my mind on when an LXC container can be a better choice than using a full VM. Do you have any precise uses cases in mind that can bring some arguments in one way or another? Are LXC more "PaaS" oriented, to run applications without hardware control? Do we always need to use VM on an "IaaS" perspective where we want infrastructure control? Regards, 回答1: I don't think IaaS needs VMs. With LXC you can define # of cpushare and Memory user limit. The thing is VMs are pretty

What do 'instances' mean in terms of cloud computing?

由 蹲街弑〆低调 提交于 2019-12-04 20:05:20
问题 While looking through the pricing of some cloud computing hosting services like Google App engine, Amazon, etc, I see terms like $0.0x per instance per hour, etc. What exactly does that mean? Is an instance = X page views, or is there any other way to estimate how many instances I would need? 回答1: Generally 1 instance == 1 machine/server (often a virtual machine). See e.g. http://aws.amazon.com/ec2/instance-types/ and https://developers.google.com/appengine/docs/adminconsole/instances 回答2:

How to Log exceptions caught in WCF service deployed on Azure

由 最后都变了- 提交于 2019-12-04 19:52:33
问题 What is the best way to log the exceptions caught in WCF service hosted on cloud? 回答1: You can take advantage of System.Diagnostics and logging your exceptions with Trace.traceError() . You can then schedule these trace statements to be periodically uploaded to table storage (maybe once a minute?), where you can then retrieve and analyze the trace statements either with an on-premise app or one running in a worker role. For example: in your worker role's OnStart(), customize the Diagnostic

Developing a Multitenant SaaS

由 Deadly 提交于 2019-12-04 18:26:08
I am developing a web application for data analysis on agricultural datasets. Actually I want to make the application to be multi tenant and I wish to deploy that SaaS application in a private cloud (in our school). I got a few basic doubt in the programming part. Do I need to develop the application in the Hadoop's map/reduce functionality? Secondly,the selection of database. Since the data are highly structural in nature (like sql) can I use a sql server to manage data in cloud? In such do I need any middleware in addition to the IaaS setup and the SaaS application? I am using J2EE

Back up AppEngine database (Google cloud storage?)

由 核能气质少年 提交于 2019-12-04 18:14:24
问题 I have an AppEngine application that currently has about 15GB of data, and it seems to me that it is impractical to use the current AppEngine bulk loader tools to back up datasets of this size. Therefore, I am starting to investigate other ways of backing up, and would be interested in hearing about practical solutions that people may have used for backing up their AppEngine Data. As an aside, I am starting to think that the Google Cloud Storage might be a good choice. I am curious to know if
