The test_coverage package has not been updated for quite some time and is not playing well with some of the fewer packages. It also doesn’t support null safety. The replacement is the new ‘coverage’ package from the Dart tools team. The ‘coverage’ package should be used for new projects. See the post here to set…
IBM organized a Hackathon in Ballarat, Australia running for 48 hours from 19th to 21st July 2019. Hosted in collaboration with Grampians Integrated Cancer Service, the aim was to come up with solutions for improving the experience of cancer patients as they go through treatment. We developed an Android app for patients to keep track…
We are going to setup Android development environment with an Android Emulator. If we install Android Studio (IDE) inside a Virtual Machine, the Android Emulator setup will fail. This is because Android Emulator is itself a Linux OS and cannot run inside another Virtual Machine. The way around this is to create two VMs in…
The sixth release of Mind Mate has a new sidebar for searching. It supports: Search for text (results are displayed as you type in search field) Search for Icons Limit the search to a selected node and its descendants Make the search case sensitive Along with other minor changes, the accuracy of task notifications is…
Just released Mind Mate version 0.5 on Github. This update significantly enhances the image handling capabilities of Mind Mate. Now, you can copy/paste images from the Web Browser, Clipboard or File System directly into Mind Mate. These pasted images are saved inside Mind Mate file, rather than links. This functionality is supported in both Mind…
Cypress.io is a newish front-end test automation tool. In my brief encounter with Cypress, I found it relatively easy to set up and get started. The development workflow from coding to writing tests and running them is refreshingly smooth as compared to other Selenium based tools. Cypress does have its own limitations though as explained…
I am starting with an objective to create a relatively faster and lightweight development VM for Maximo 7.6.1. To cut down on the size and hopefully gain bit more speed, I am going to use the following components: Operating System Ubuntu 16.04.5 LTS (64-bit) Database Oracle 11g Express Edition Application Server Websphere Liberty 18.0.0.2 Virtual…
I have been optimizing the performance of a WordPress site for a couple of days and managed to shave off about half a second from page load times and significantly improve the performance scores. Evaluating Performance The first step towards optimization is to measure the performance of your site and identify the issues and bottlenecks.…
Public-key Cryptography is asymmetric meaning the key used for encryption cannot be used for decryption. There is a pair of keys, if the message is encrypted with one key, then the other is required for decryption. How Public-key Cryptography works conceptually? Let’s say Alice and Bob want to exchange messages in a secure way. To do it using…
Computing PowerMod is required for implementing public-key cryptography as it is used to encrypt and decrypt data. Calculating it by regular arithmetic (i.e. calculating pth power of a) doesn’t work with large numbers used for encryption. That’s where PowerMod helps, it calculates the result by keeping the numbers significantly small and within range of the integer data type.…
