How to Log exceptions caught in WCF service deployed on Azure

怎甘沉沦 提交于 2019-12-03 13:01:01
What is the best way to log the exceptions caught in WCF service hosted on cloud? 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 Manager to upload your trace data to table storage. In this example, it's uploading every minute, to the

Running ssh on Amazon EC2 instance on port other than 22

问题 I am not able to access Amazon EC2 instance via ssh as i am behind a firewall. So, i thought of running ssh on port other than 22, like 80 or 443. I tried starting Amazon EC2 instance via Web Management Console with following 'user data': #!/bin/bash -ex perl -pi -e 's/^#?Port 22$/Port 80/' /etc/ssh/sshd_config service sshd restart || service ssh restart The idea being that the above script would execute on instance startup and switch ssh from port 22 to port 80.

What is the difference between private cloud and public cloud?

What are the differences between private cloud and public cloud ? Please define both and giving examples with usage. 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. A hybrid cloud environment consisting of multiple internal and/or external providers will be typical for most enterprises. You will get more understanding here . The same as the difference between an intranet and the

Area covered by a point cloud with R

限于喜欢 提交于 2019-12-03 12:28:36
I have a cloud of points scattered in a 2D Euclidean space. I would like to calculate the area inside the polygon linking the most extreme (=peripheral) points of the cloud. In other words, I would like to estimate the area covered by the cloud in this space. Is there a formula in R? Thanks a lot for any response Julien This is called the convex-hull problem; R built-in chull function should do the work. To count area, you may use a formula from here . EDIT: Even better; splancs package has areapl function. So the function solving your problem should look like this: cha<-function(x,y){ chull(x

Back up AppEngine database (Google cloud storage?)

China☆狼群 提交于 2019-12-03 12:04:29
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 anyone has experience using the Google Cloud Storage as a backup for their AppEngine data, and what

Can Git and iCloud Drive be effectively used together?

主宰稳场 提交于 2019-12-03 11:06:21
In the same flavor as this question , are there any possible complications that can arise when using the two services together? I'd be concerned about the upcoming macOS Sierra's new Optimised storage feature, where not all files in iCloud Drive are stored locally and may instead be requested on-demand. From my tests, it appears git doesn't trigger the OS to request the file, and instead picks up the placeholder file, named something like .original_filename.icloud . No, they shouldn’t be used together. Apple says “You shouldn’t store app folders, libraries, or .tmp files in iCloud Drive.” .git

What's the difference between zookeeper vs spring cloud config server?

What's the difference between zookeeper vs spring cloud config server? They both store configurations in server and make them available to clients. When should one be used over the other? What's the difference between zookeeper vs spring cloud config server? With the Spring Cloud Config Server you have a central place to manage external properties for applications across all environments. The concepts on config server map identically to the Spring Environment and PropertySource abstractions, so they fit very well with Spring applications , but can be used with any application running in any

Google BigQuery Underlying Architecture

独自空忆成欢 提交于 2019-12-03 10:41:08
问题 So I just started messing around with Google BigQuery about 10 minutes ago, and I was wondering if anyone is aware of the underlying architecture that they're using to store the data? For example, is this just the next generation of their own BigTable infrastructure? Also, is it clear what sorts of strategies they're using for indexes, index rebuilds, etc? I'm just trying to analyze whether this is mature enough at this point where you can be 100% sure of what's going on with your data end-to

OpenCV in the cloud

放肆的年华 提交于 2019-12-03 10:08:43
问题 The question may seem dumb to those experienced with cloud development, but coming from the desktop world I can´t exactly figure out the solution by myself. I have a loads of code using opencv, some of it with an api. Question is, would it be possible to get opencv running on a remote server (let s say heroku or S3)? I think the only way would be to send any dependency (and there is a lot) within the code? I m developing in Python. Thanks ! EDIT : My very first idea is this one : https:/
