It’s been a while since I’ve gotten a few things off of my chest and since I’m always full of peeves and annoyances I thought it was time to unleash: Due to the immensely negative response to any tweet about crypto from my blog account, I created a second account just for crypto musings. I’ll be honest — it hurt that I needed to do that. I’ve always felt readers and followers were on a journey with me but maybe the truth is that the majority of my value is quick tips and code to get people past a single problem. Last week I contributed to Uniswap, the well known decentralized exchange with billions of dollars in locked value and used by millions of DeFi investors each day. It was a small change but putting my footprint in as many places as possible is important to me. Good for the ego but also helps to make me feel valuable and energized. I couldn’t be prouder to be working the amazing team at MetaMask to build the secure future of Web3 and change the landscape of trading, voting, and money. The potential of blockchain, Web3, and the entrepreneurial spirit that comes with it makes me incredibly excited to wake up each day. It’s taken a while to admit to myself but Mozilla’s layoffs were mostly an effort to bin experienced, highly paid senior employees and replace then with younger, cheaper employees. Not bitter, just honest, and it’s a good reminder that your employer is not your friend, not matter how much they speak in terms of family. I grew up...
AWS S3 provides a place for us to store files off of our servers. There are some big benefits to this: Using S3 now (even in single-server setups) can reduce headaches in the long run. Here’s what you should know! There’s two places to configure things for S3: If you check your config/filesystem.php file, you’ll see that s3 is an option already. It’s setup to use environment variables from your .env file! Unless you need to customize this, then you can likely leave it alone and just set values in the .env file: 1# Optionally Set the default filesystem driver to S3 4# Add items needed for S3-based filesystem to work 9AWS_USE_PATH_STYLE_ENDPOINT=false The config/filesystem.php file contains options like the following: 3 // ‘local’ and ‘public’ ommitted… 7 ‘key’ => env(‘AWS_ACCESS_KEY_ID’), 12 ‘endpoint’ => env(‘AWS_ENDPOINT’), 13 ‘use_path_style_endpoint’ => env(‘AWS_USE_PATH_STYLE_ENDPOINT’, false), There’s a few options there we didn’t use in the .env file. For example, the AWS_URL can be set, which is useful for using other file storage clouds that have an S3 compatible API such as CloudFlare’s R2 or Digital Ocean’s Spaces. AWS Configuration Within AWS, you need to do 2 things: Like anything in AWS, creating a bucket in S3 involves looking at a ton of configuration options and wondering if you need any of them. For most use cases, you don’t! Head to the S3 console, create a bucket name (it has to be globally unique, not just unique to your AWS account), choose the region you operate in, and leave all the defaults (including the ones that labeled “Block Public Access settings for this bucket”). Yes, some...
Enterprise mobile app is a sophisticated software system designed, deployed, and maintained to deal with routine business operations. The app is developed according to the company’s global strategy and makes certain app functions available on mobile devices to streamline business tasks and enterprise operations.

The Australian High Commissioner, Jon Philp, presented the certificates Australian government being the enabling partner of the program. This course was made possible by an MOU between Australia-PNG Government partnerships, which was executed in 2018. Department of Information and Communication Technology Secretary, Steven Matainaho said under the MoU for Cyber Security signed by the two governments almost five years ago, further assistance was given by the Australian government to operationalize the National Cyber Security Shelter project. That project offered awareness and training primarily to IT Managers and IT officers within the Public Sector. “Quite a lot of recipients passed through but today was just a day to acknowledge those that actually completed the programme. The programme consist of Tier 1 & Tier 2 in Cyber Security. That is analyst training and basics of not only IT only, but Cyber Security Functions and its role within the IT space,” Mr Matainaho said. Key stakeholders involved in the Cyber Security include the Office of Security and Coordination Assessment under the Department of PM, with support from National ICT Authority as the regulator and of course the ICT Department. It was an event also to recognize the partnership between Australia and PNG. Australian High Commissioner, Jon Philp emphasized on the relevance and importance of cyber security in the country and the world. “It’s a really important partnership for us in cyber security. It’s important to remember why it’s important, not just in your careers and your jobs but the lives of our country and in fact the lives of millions of people.” Philp said. High Commissioner Philp emphasized the practicality of Cyber...
The 7 R Packages You Should Be Using for Data Visualisation With example code and free datasets “It’s not what you do, it’s how you do it.” ― Cheri Huber, Suffering Is Optional: Three Keys to Freedom and Joy Having data but not knowing how to visualise it is what I call self-inflicted suffering. So, like Cheri said, there are 3 keys to freedom and joy — my take on it — Data + R + these 7 R packages. The Data The 7 (Nonfatal) R Packages Let’s start with the original library that makes R the best language for visualisation — ggplot2. I am making use of a dataset from Kaggle, which you can find here (Sustainable Development Solutions Network, 2019, License CC0: Public Domain). The data looks at the state of global happiness: Code An extension library to ggplot2 is called ggforce, which was developed by Thomas Pedersen. It has the added functionality of highlighting different groups and their specific features in your data, helping you to tell your story more effectively. You can see some ggforce examples here. 2. ColourPicker Don’t waste time googling the hex codes for the colours you want to use— Rather make use of ColourPicker! This is particularly useful if you are required to stick to a customized colour palette. See the demo below: Here is the code I used in the demo: If you would like to read more about creating custom palettes, see an article I wrote here. 3. Esquisse Have the data but not sure how to visualise it? Or, not sure how to write the code in R?...
