Recently I was debugging the issue with DotNetBrowser and external call from JavaScript. I had the following:
|
1 2 3 4 5 6 7 8 9 10 |
FleepBrowser.Browser.DocumentLoadedInMainFrameEvent += delegate(object sender, DotNetBrowser.Events.LoadEventArgs e) { FleepBrowser.Browser.ExecuteJavaScriptAndReturnValue("window").AsObject().SetProperty("external", new ExternalCodeHandler { NewMessagesCountCallback = delegate(int count, int allCount) { // ... } }); } |
So I configure the browser and then set external object to handle callback. The callback is a method accepting two integers. It was called using…

Spark supports multiple encryption schemes. You can use client side encryption, server side encryption, etc. What wasn’t working for me for a long time is reading encrypted data and writing as a plain text. Before reading I was configuring encryption and this was…
Today I’m going to share my configuration for running custom Anaconda Python with DGL (Deep Graph Library) and mxnet library, with GPU support via CUDA, running in Spark hosted in EMR. Actually, I have Redshift configuration as well, with support for gensim, tensorflow,…
Last time we saw how to connect to Redshift from Spark running in EMR. Provided solution was nice but allowed for reading data only. Sometimes we might want to run any DDL or DML query, not only simple read statements. To do that,…
Today I’ll share my configuration for Spark running in EMR to connect to Redshift cluster. First, I assume the cluster is accessible (so configure virtual subnet, allowed IPs and all network stuff before running this). I’m using Zeppelin so I’ll show two interpreters…
