Voila!

Recently, I had installed the Deno v0.18.0 using brew on macOS . Then tried couple of samples given there. I was amazed to see, how closely it behaves like Golang . When we run the script for the first time, Deno downloads all the dependencies provided in the import statement that is required to run the script. When I ran the same script next time then it doesn't download any dependency. So that means it caches all those dependencies and uses the same next time. Now I was eager to see the cache , but can't find it at the usual locations but after some time with the help of Google , I was able to find the correct location. So I thought it would be pretty useful to put it in blog for ready reckoner. So here is the sample path on all major platforms Platform / Location Binary Cache Windows C:\Users\me\AppData\Roaming\deno\ C:\Users\me\AppData\Local\deno\ macOS /Users/me/.local/bin/ /Users/me/Library/Caches/deno/ Linux /home/me/.lo...

Few years back, we faced a hard technical problem while working in IoT project. We were having a mobile app to control smart electronic appliances that consumes our web-service. A third party somehow managed to use our mobile app with their service. We assume that they had reverse engineered to crack the services. So we had to protect our mobile app which was cordova based cross platform app I have been allocated to analyse this issue and propose a solution. So during my initial analysis I found that first we should secure the mobile application installer because Android's .apk installation file usually packaged together all the resource files used in the hybrid project. Crackers could reverse engineer it to get those files. I know that we can ensure protection only by increasing the level of security. So I minified all the files, bundled together and applied obfuscation over it; which made hybrid portion bit more secure. After this I used Arxan to protect the mobile app at b...
