Next Level Conspiracy Insanity: Direct Energy Weapons Allegedly Used To Start Australian Bushfires

I love a good conspiracy theory. Some of my favourite conspiracy theories include the Royal Family being shape-shifting lizards, part of some global reptilian elite controlling the world or Alex Jones’ famous rant where he claims the government is putting chemicals into the water turning frogs gay.

The late-2019 Australian bushfires which have burned into 2020 have attracted some crazy individuals claiming all kinds of crazy things. People have lost their lives, thousands of homes destroyed, towns completely wiped, millions of hectares burned, over 1 billion animals estimated to have been killed.

It all started when Barnaby Joyce helped start the rumour that the Greens were responsible for the bushfires by proclaiming they have stopped needed fire-reduction efforts and locked up national parks. In amongst all of this, another conspiracy has been spreading amongst the inner crazy circles of the internet.

Allegedly, some elite secretive entities with an agenda for a high-speed rail line started the fires in the needed areas where the line would go and furthermore, an agenda to force people in regional areas into cities so they can be “more easily controlled”.

I would say you can’t make this stuff up, but here we are talking about it.

One of Australia’s most well-known weather centric Facebook groups Higgins Storm Chasers has also helped spread the rumour to their 10k followers.

This post, in particular, loses credibility almost instantly by claiming that dry lightning is a new and made-up term. Ignoring the fact that dry thunderstorms are well-documented and occurring phenomena that happen in dry areas.

As can be expected, crazy attracts crazy. The comments section, things start to spiral out of control quite quickly. People start sharing images of what they believe to be chemtrails and planes spray chemicals in the sky, presumably to cover bushland in some kind of combustible material.

The thing is, the unprecedented fires we are seeing don’t need anything sprayed in the areas to make the fires spread. The fuel is the incredibly dry bushland catching alight.

Furthermore, there are much better ways to make money than a train line. Look to other established rail lines and services, Amtrak doesn’t turn a profit and it turns out in the UK private railway operators have realised that they’re not profitable either.

Whoever these elite corporate shadow entities are, they have a terrible business sense if they think a high-speed rail line is going to be their ticket to riches. Given the exorbitant cost of constructing such a line, it would take decades for it to earn the money back (if it ever manages to achieve profitability).

These bushfires are being spread by insanely dry conditions, caused by climate change. We need to be smart and plan accordingly for the future because this is just going to keep happening. We can let the crazies play in their little crazy corner on the internet while the sane ones try and come up with solutions to stop these fires from spreading as badly as they have.

What Comes Next After USB-C?

I have the weirdest and sometimes most profound thoughts about the most useless stuff. I actually asked myself this question whilst in the shower this morning: is there going to be a USB-D? Do we need a successor to USB-C or is it good enough for the time being?

When these types of questions pop into my head, I have to Google them. I actually stepped out of the shower and before reaching for a towel, I grabbed my phone and had to find out. With the water dripping onto my phone screen and floor, I set out to find the answer.

Given the iPhone doesn’t even support the USB-C standard yet (opting for its own Lightning Connectorâ„¢) I wonder if it’s due to limitations in the standard or fact Apple doesn’t want to have to change their cables again, after the controversy they generated a few years ago when they did it.

Anyway, back on the topic at hand. In terms of the USB-C specification, it is relatively quite new. It wasn’t published and finalised until August 2014, which isn’t that long ago.

It turns out the answer is not exciting at all, there is no publicly announced successor to the USB-C cable standard. In terms of capabilities, it seems USB-C is capable of supporting quite a high throughput with the recently announced USB 4 standard supporting speeds up to 40gbps (which is super fast) and will require compatible USB-C cables to take advantage of it.

It is naive to assume that USB-C will be as good as it gets. Once upon a time, USB-A and USB-B were probably considered enough and then technology evolved and times changes.

I wonder though, will they call it USB-D or something a little less silly-sounding opting for something like USB-Next or USB-Z?

Preferring If Statements over Ternary Operators In Javascript

Every so often thought-pieces will go around proclaiming that you are writing code the wrong way and that you should be writing your code this way instead.

One such opinion I have seen (and will not link because this isn’t a takedown) is recommending the use of Ternary Operators in Javascript over if statements.

While ternaries can make your code look cleaner in some cases by replacing multi-line if statements with one-liners, there are instances where they fall apart quite quickly. Ternary operators exist in all programming languages and the problems they can introduce into a codebase are universal.

Ternaries are hard to read

Sure, they might look cleaner, but ternaries can needlessly make code hard to read. This is the problem I have with “clever coding” and some developers pursuit to write the most convoluted code in an attempt to condense things.

const canAccess = user.isAdmin || user.isEditor || user.level > 6 ? true : false;

It’s a simple one-liner, but there is a lot going on here. Replaced with an if statement, things get a little easier to read.

let canAccess = false;

if (user.isAdmin || user.isEditor || user.level > 6) {
    canAccess = true;

Understandably, this is an exaggerated example and even so, there is room for improvement here. But, my eyes are instantly drawn to the if statement, it is easier to read and if I need to change it, it will be easier to change as well.

Ternaries fail at dealing with complex conditions

The above example is quite a simple set of conditional checks, but what happens in a situation where things are more complex? A good example is detecting keycodes on the keydown event in Javascript and reacting accordingly.

While in simple use-cases it is more than fine to use a ternary, complex scenarios with multiple conditions should be avoided like the plague. If you need to check multiple values or check multiple expressions, a ternary condition will be a nightmare.

const prevNext = (e.keyCode == 38) ? 'prev' : (e.keyCode == 40) : 'next' : null;

This is a relatively tame example of multiple expressions, can you imagine throwing more into the mix?

Ternaries are hard to debug

If you have a one-line ternary expression in your application, good luck setting a precise breakpoint. This is where the differences between a ternary statement and if statement is truly highlighted. Sure, you could use a console.log if you wanted to debug, but setting a breakpoint is not going to be possible.

Code that is broken up into multiple lines might not look as appealing as a condensed ternary condition, but at least you can set a breakpoint and go through it line-by-line to debug the flow.

I am not saying that you shouldn’t use ternaries, because they have a purpose. But to go as far as recommending their use over if statements in general defies all common sense.

The Real Reason Virtual Reality (VR) Has Never Taken Off

Recently, the BBC published an article titled Why we’ve never fallen in love with virtual reality in which they discuss virtual realities lack of mainstream consumer adoption.

The article then goes on to talk about one VR segment that is thriving: group entertainment. Specifically, virtual reality arcades, theme parks leveraging virtual reality in rides and offering an affordable means of immersing yourself without getting into debt.

Truly immersive virtual reality experiences in 2020 are amazing. In countries like Tokyo, they have numerous public places where VR is employed for fun experiences. Disneyland has been showcasing the power of virtual reality for some time now.

One of VR’s biggest problems in the consumer home entertainment space is the cost. The technology is on the high-end of the spectrum, often requiring the headset, sensors and a computer to power it.

While the cost of the headsets themselves have gone down over the last few years, building a PC powerful enough to provide a low-latency, immersive and smooth experience requires top-shelf components (the most expensive being one or two graphics cards).

The Oculus Quest which is an attempt to not rely on external hardware and provide an all-in-one virtual reality solution is a step in the right direction towards mainstream adoption. Still, the cost puts in way above a gaming console and the Quest is considered low-end VR.

It goes a step above those horrendous standalone headsets like the failed Google Daydream which has been shut down by Google and requires you to put your phone inside of it.

Virtual reality isn’t dying, it’s just considerably behind optimistic estimates of where it was heading. 2016 was allegedly meant to be the year of virtual reality, really, we are still 3 to 5 years away from mainstream VR adoption. The latest, we won’t see VR truly take off until 2025.

Estimates of mainstream VR adoption were about ten years behind if you ask me. However, we cannot discount companies like Oculus and Sony who took the plunge and invested in early generation headsets.

I believe headsets like the Quest which do not require expensive water-cooled gaming PC’s with $1500 graphics cards in them are the beginning of a new era of VR. Screen technology is getting quite good, refresh rates are increasing and experiences are also getting better.

The one thing VR is also missing is a killer app. Something synonymous with VR like Facebook, Google and Twitter are with the internet, there is no one killer app that springs to mind for people when they think of VR. However, I think that will eventually change.

We also cannot discount the fact that VR will never appeal to some people. For some, VR is an uncomfortable nauseous and disorienting experience. I think the future of VR is a hybrid of both virtual reality and augmented reality, not one over the other.

Once the cost of VR comes down to a level that is comparable with a gaming console like the Playstation or Xbox, we are going to see considerable adoption and a new industry that will start a gold rush. It hasn’t started yet, but it is coming.

The real problem to VR adoption right now is the cost. It’s a problem other industries like the electric vehicle industry are experiencing, but once the economy of scale kicks in, that’s when the adoption truly begins.

Should I Choose Firebase Cloud Firestore or Realtime Database?

When it comes to Firebase for newcomers, the first point of confusion in what is quite a simple platform is what should you choose for your database: Firestore or Realtime Database?

As someone who has been using Firebase for quite a few years, there was a time when Firestore never even existed. Initially, it used to just be Realtime Database and that was that. A couple of years ago, Firebase introduced the Firestore database which is the next evolution of databases on Firebase.

While Firestore has been in beta for some time, I can tell you based on experienced that it is anything but a beta product. The difference between Firestore and Realtime Database used to be the reliability. For a while after introduction, Firestore’s reliability was terrible, regularly going down.

In 2020, Firestore seems to be quite stable. I use it for several applications, including a highly trafficked cryptocurrency exchange and I have not witnessed a period of downtime with Firestore.

The ability to query data in more flexible ways is more appealing than Real-Time. Previously, you would have to pull down entire trees of data (which could be massive) and then sort through them in either Node.js or on the client because of the lack of querying, this is why Firestore was created.

Even so, Firestore still has its limitations when it comes to complex querying and you should absolutely read up on what those are. You can’t do everything that a normal RDBMS allows you to do or even completely what NoSQL solutions like MongoDB offer, but all limitations have workarounds.

Rather than reiterate the technical differences between the two, there is already a great official post on the Firestore site that details the differences between the two.

Without delving too deeply into the specifics, you should choose Firestore and I would not recommend anything else. It offers way more powerful querying (which is important in a database), more flexible ways of storing data (Real Time can get messy) and it is still quite cheap.

Are We Finally Getting A New System of A Down Album In 2020?

All signs are pointing to yes. System of A Down frontman Serj posted an image of himself in the studio working on what appears to be music for a System of A Down.

Many might be quick to say this could just be Serj working on more solo material, the hashtags tell a different story at the end, using the band’s name as a hashtag.

For years there has been rumour and speculation a new album is happening. Then various members speaking out about the band’s inability to get on the same page musically, could they have found a way to work past the problems they were happening?

We have all been let down by the possibility of a new SOAD album, only for Serj or someone else in the band to come out and say it is not happening. Time will tell.

Thoughts On Ember Octane

When it comes to JavaScript frameworks, few can lay claim to the longevity of Ember which just turned eight years old. To give readers some perspective, Ember is about as old as AngularJS (the first version of Angular), older than React, older than Vue and many other options out there. It harks back to the days when IE6 was still a browser many of us had to support.

To the surprise of some who abandoned Ember (and JavaScript frameworks in general) years ago, Ember just released a large update which changes and improves Ember in many facets. For years, Ember has been trailing behind other frameworks and libraries. Even though updates were still being made, Ember has always felt like a relic of Web yesteryear.

Despite trailing behind newer, faster and smaller options, Ember has enjoyed success at numerous companies including LinkedIn and Intercom. Nobody can argue that Ember isn’t used or that it is even dying, it’s just not that popular any more. It’s hard to deny that React has eaten front-end development.

With Ember Octane, many facets of Ember have been improved, Ember applications are still overly verbose and the templating syntax which uses Handlebars feels outdated.

In Octane, some of the changes actually resemble that of Aurelia dating back to 2015. Previously, view-models and templates were located in separate directories. The old approach looked like this:


In Ember Octane, this now resembles that of frameworks like Angular or in my opinion as mentioned, more closely to Aurelia:


As you can see, the view-model and template are in the same directory now. Likewise, Ember Octane introduces a new decorator for computed properties called @tracked which is reminiscent of Aurelia’s @computedFrom decorator. A similar concept further cemented by the introduction of a decorator called @computed in Ember Octane.

I think Ember Octane is a step in the right direction. Some parts feel inspired by React and other parts feel inspired by Aurelia. Still, looking at Ember, it feels overly complicated and like it is still playing catchup with Aurelia from 2016 or really, every other established framework using modern Javascript syntax.

For me personally, there is nothing in Ember Octane that is exciting or innovative enough that it would suddenly win back developers who left Ember or have eschewed it for other options such as React and Vue. Still, it is great to see the project is maintained and this is all a positive step in the right direction.

I don’t want people to misconstrue this post as a beat-up of Ember with a hidden agenda to promote another framework. I think the more frameworks and libraries there are, the better. But when you’re competing with the big daddy React or up and coming superstar Svelte, you have to bring something substantial to the table and really, Ember doesn’t feel that different when you dig beneath the surface.

Is Ethereum Dying?

Or is it already dead?

The once-promising blockchain and beloved smart contract project seemed to be at the top of the world. From a high of $1431 in January 2018 to its current low of $126, it seems whatever hopes people have for Ethereum have faded quite a bit.

Despite the fact that Ethereum still holds the number two spot on Coin Market Cap Ethereum has fallen out of the limelight somewhat with developers. On State of The DApps, Ethereum accounts for only three of the top ten applications. Klaytn accounts for four of them, Steem accounts for two and NEO just one. In the top five, Ethereum only has one DApp.

Vanity metrics aside, given Ethereum was one of the first smart contract platforms and holds the coveted #2 spot, you would expect more popular applications to be using it. However, over the last two or so years, many projects and exchanges have moved away from Ethereum to their own solutions.

Ethereum used to be ICO blockchain. Almost every ICO in 2017 was an ERC20 token. Fast forward to 2019 and the projects that are still alive, quite a few of them have moved away from Ethereum. (formerly known as Monaco Card) previously used Ethereum, until they created their own blockchain called Chain (CRO). In early 2019, Binance famously ditched Ethereum for their own solution as well Binance Chain.

Tron and EOS are also two other blockchains which received their funding through Ethereum and then subsequently created their own competing blockchain. It seems Ethereum has become the gateway to other blockchains.

One of Ethereum’s biggest problems is that it has serious scaling issues. I am sure you all remember CryptoKitties which famously crippled Ethereum a couple of years ago. It also turns out that Tether may also be to blame for Ethereum’s high network usage and problems.

Having said that, many blockchains have the same scaling problems. Bitcoin is also quite full, EOS recently experienced some serious problems with their network as well.

While the anticipated Ethereum 2.0 release will alleviate some of the problems by moving away from proof-of-work to proof-of-stake, nobody can agree on anything. There has been a tonne of infighting within the Ethereum team and associated entities contributing to the blockchain.

Allegedly the first upgrade will be happening in January 2020, but given the turbulence, Ethereum has experienced with nobody seemingly able to agree on anything, I would actually be surprised if that happens. People are afraid of Ethereum 2.0 and the changes being proposed.

Even one of the co-founders of Ethereum recently sold off 90,000 ETH worth $11 million US dollars. Another nail in the coffin of an already fractured and turbulent cryptocurrency project.

Given Ethereum was one of the first general-purpose smart contract blockchains, perhaps it was inevitable that it would eventually lose some of its popularity in favour of other more modern solutions who have the luxury of beginning from scratch without having to worry about an entire legacy ecosystem built around them.

I don’t think Ethereum will truly die, but there are so many better options out there now ranging from Steem to EOS, to Stellar, Tron and Klaytn that make Ethereum look antiquated and clunky. Ethereum is no longer the first choice that comes to mind for many DApp developers.

Select Change Event Not Firing When Using Characters On Keyboard

Here is a nice bug-not-bug to close out in 2019. One of my Trello cards detailed what sounded like an error:

When toggling between two options (yes and no) in a dropdown, entering “y” changes to yes and quickly entering “n” does not switch to no. However, waiting a second you can change between them.

Some initial debugging suggested this was not actually a bug in our application. But, I knew if I was going to get the ticket closed off as not a bug, I had to have an explanation.

It turns out that browsers (well at least in Chrome and Firefox) select dropdowns are searchable by offering a delay allowing you to type in long values. The way I highlighted this was creating a dropdown with four options:

  • Yes
  • No
  • YNo
  • NYes

To highlight the error I created a JSFiddle demo here. The first dropdown contains the above options. Try pressing “Y” and then “N” quickly after, the selected value will then be “YNo” highlighting the searchability. Similarly, entering “N” followed by “Y” will yield “NYes” selected.

There is also a second dropdown with some years from 1988 to 1993 in the above linked JSFiddle demo. Try selecting the dropdown and then entering 1993 (which is the last option) you will see the searching feature in the browser selects 1993.

So, not a bug, just a browser feature. Admittedly, I didn’t actually know you could search values in a dropdown this way. I usually use my mouse to select values in a dropdown. We have some people on our team who shun the mouse and navigate through our main app using their keyboard.

Quick & Easy Way To Reset Mocks & Spies In Jest

When working with mocks and spies in Jest, it is quite easy to fall into a trap where they become stale (especially in cases where pure functions are not being used). Heading to the documentation for Jest yields a lot of similar-looking methods for restoring mocks, clearing mocks and resetting mocks.

This is where confusion sets in. What is the best practice? Which ones should I call to ensure my tests don’t have stale mocks or spies? Even I struggled with this aspect.

In my Aurelia applications, Jest is my prefered means of test tool. In my trial and error, I have settled on the following in my tests which ensures all mocks and spies are reset between tests being run.

  afterEach(() => {

The jest.resetAllMocks method resets the state of all mocks in use in your tests. It is the equivalent of manually calling mockReset on every mock you have (which can be tedious if you have a lot of them).

The jest.restoreAllMocks method restores all mocks back to their original value, ONLY if you used jest.spyOn to spy on methods and values in your application. It is important that you use spyOn where you possibly can.
