VDSL Modem in Bridge Mode: How does it work?

In networking terms, a Bridge is a way in which multiple networking interfaces (physical or virtual) can be made to function as as if they were a single network interface. In general terms, this is how clients associated with a router on both wired Ethernet and wireless can communicate together. In my specific case, I have a VDSL modem which is configured in bridged mode and plugging into my Turris Omnia router to enable the Turris to connect to the Internet.

With details scarce online about exactly how this black magic works to allow my Ethernet-only router to connect to …

How to buy alcohol at Costco without a membership (in Hawaii)

There’s a variety of anecdotal information online about whether it’s possible to purchase alcohol or liquor from membership-based stores (such as Costco) in the United States if you don’t have a paid membership. Some sites quote federal, state or local liquor licensing laws as to why it isn’t possible for “alcohol clubs” to exist or similarly vague or unreferenced sources.

Having recently travelled to Hawaii, I wanted to test these ‘theories’ out for myself and see whether I could get a good deal for something to take back home as my duty-free allowance.

My research took …

Ordering a Turris Omnia in Australia (2018 pricing)

The Turris Omnia is an amazing home router. Not only did it start from humble beginnings from a crowd-funding campaign but it’s open source, has a huge community and supported by CZ.nic, the association responsible for domain names the Czech Republic.

I won’t wax lyrical about the benefits of the device as you can discover that for yourself, but rather I’ll tell you how you can order one of these if you happen to live in a country where the the resellers don’t ship to. The devices are sold through Amazon.de and various other …

Can’t change Apple ID email address? Try waiting 30 days

Like it or not, Apple plays a critical part in the app-based economy these days. Part of this is having an Apple Developer account in order to release apps to the App Store™️, and in order to get an Apple Developer account you need an Apple ID. In order for the Apple ID to be able to become an Apple Developer account, it needs to be considered to be “over 18”, even if it’s a company account and a Date of Birth makes no sense whatsoever. This is where I got stuck.

Let’s say you don’t realise …

Resolving an NS_ERROR_FILE_CORRUPTED error in Mozilla Firefox

I use Mozilla Firefox as my browser and occasionally I’ve found that certain resources (typically JavaScript or CSS files) may fail to load because of an error NS_ERROR_FILE_CORRUPTED, which is displayed in the console. For me, this is rarely seen, though I’ve experienced the issue a few times on Trello.com and another on our corporate website CMS. This has the effect of preventing whatever that resource was from loading, so in the case of CSS it won’t display and in the case of JS it won’t run. On Trello, this resulted in a fully broken …

iMessage and Google Talk not working on macOS High Sierra (10.13)

I recently upgraded my computer to macOS 10.13 and found that my iMessage (in Messages.app) wasn’t working entirely and that Google Talk in the same app would only receive messages and not send.

Starting with the Google Talk issue, that’s an easy one. Apple has removed “official” support for Google Talk from Messages.app but they’ve clearly left the code in place that allows your old account to login, connect and actually receive messages, but helpfully added a dialog that says “Your message could not be sent. Support for the targeted service Google Talk has …

Static sites, continuous deployment and HTTPS with Netlify

I’ve been doing a variety of things pertaining to web security in recent weeks and one thing that’s been gnawing at my brain is the fact that my blog could still only use insecure http:// because of GitHub Pages. My blog’s content was using GitHub Pages for its serving and gh-pages really hasn’t been seeing a lot of love - that I know of - since its inception a few years back, especially since the development of concepts like Let’s Encrypt with free SSL certs for the web.

I felt I probably should have taken a more …

Creating a macOS Recovery Partition without reinstalling OSX or re-running your installer

Restoring from a Time Machine backup - at least for me - won’t furnish you with a Recovery partition. This is bad news because the only official way of getting a recovery partition is to reinstall macOS. This seems a little counter-intuitive because isn’t the point of backing up your computer so you don’t have to reinstall your OS? Anyway, let’s get to creating your recovery partition without a reinstall or without 3rd party tools. It’s easier than you think!

Note that this process worked for me on macOS Sierra (10.12). I give no warranties that …

Tips for the USA: Car Rental, Travel, Navigation and SIM Cards

I’ve travelled to the USA a few times over the past years and typically start the trip from California. The United States is a big country with that comes complexity and a lot to learn as a visitor. This short guide covers a few key things that an Australian in the States needs to know. If you’re from another country, it’ll probably help you too but just keep in mind that things are geared to Australians.

All info is correct at the time of writing. Also, it goes without saying that all information is offered without any …

Adding a Vim modeline in a Markdown document

A short tip: Markdown doesn’t have any form of official or non-printable markup in its language definition (that I could ascertain) so adding a Vim modeline into a document needs a little bit of massaging. You could include the modeline inside a HTML comment, but the better option that I found was to do this at the end of the document:

[modeline]: # ( vim: set fenc=utf-8 spell spl=en: )

This uses the link label syntax to establish a link called modeline, point that at the URL of #, and then use the title of that fake link to set our …
