Interesting Railways Documents


Putting this information up here for future keeping. I seem to need to keep referring to these from time to time and it will be handy to have them saved somewhere.

Missing Instant Hotspot on MacOS


One problem that keeps coming back on my MacBook Pro is that the Instant Hotspot option in the WiFi menu (in the menu bar) disappears.

Don’t confuse this with the Personal Hotspot feature of your phone. Instant Hotspot is part of the Continuity suite that uses your AppleID to make your iPhone’s hotspot feature available to your Mac even if the iPhone has the Personal Hotspot turned off.

After spending some time googling around for solutions to the missing option I worked out that I had to be searching for “Instant Hotspot” instead. I then started to get somewhere.

The fix that worked for me was step three from here.

I had to sign out of iCloud on my Mac and then sign back in. I didn’t have to do it on the iPhone.

Ive hit this issue three times now. No idea what the cause was tbh.

Useful man pages in your browser


A new useful *nix tool popped up in my Twitter timeline a while back.


Lede says Simplified and community-driven man pages and it does what it says on the tin.

If you’re a *nix admin you know the drill of looking up man pages for *nix tools. You’re solving some problem and need to grok an *nix command options and/or refer to a sample of how the tool is used. man {toolname} is the way to do it.

Frequently though the result is usually page and pages of esoteric information about the tool most of which you will never learn and will take you a lot of time to wrap your brain around. Sometimes there will be examples, waaay at the bottom of the page and often those usage examples are pretty light on information.

This is where http://tldr.sh/ comes in. Put your *nix tool name into the sample at https://tldr.ostera.io/ and it will display useful help. Example: https://tldr.ostera.io/tar

But it doesn’t end there. The page also has many community contributed clients. Scroll down the page at http://tldr.sh/ for the full list.

My favourite use of it is to add the https://tldr.ostera.io/ as a search provider in your browser. Chrome in my case. Open your Chrome settings and add a search engine with the config as below.

Now, in any search bar in Chrome you can type tldr {toolname} eg tldr tar and it will display the results right there for you. A convenient way to get useful information about *nix tools.

EtreCheck – A simple Mac OS health check tool


I had to help a friend the other week to resolve some page hijacking that was occurring on their Mac. See https://discussions.apple.com/docs/DOC-8071. I was surprised to learn that such a thing actually happens with Macs and Safari.

I needed a quick way to run a health check of the Mac OS and found EtreCheck. Recommended.

Evernote account deletion?


I severed the tether to Evernote a long time ago for a few different reasons including security, privacy and the plain fact that the client was just getting too monolithic and slow.

I finally got around to contacting them last week to delete my account. Their support team sent me to https://help.evernote.com/hc/en-us/articles/208314088 which has everything you need to do.

The last two steps are a problem though. The second last step is to deactivate your account. The last step is to contact them and ask them to delete the account.

The problem is, is that the last step requires you to login with your account credentials you deactivated in the previous step.


Reporting Damage to Australian Telco Infrastructure


I recently overheard a conversation that Dave Hall (@skwashd) was having with Telstra regarding a busted pit cover near a bus stop in his neighbourhood on Twitter.

Telstra was kind enough to reply with some useful links on how best to report this. Kudos to the Telstra SM team, they receive a lot of grief from customers all day and still come through. It takes a special type of person to stick at that job.

For normal every day reports head over to https://say.telstra.com.au/customer/general/forms/report-damage-to-telstra-equipment?red=social-care-LSW:rwwr

For equipment that may contain asbestos report the problem to 1800 067 225. More information available from https://www.telstra.com.au/aboutus/media/emergencies-incidents/asbestos.

Optus have a page at https://www.optus.com.au/shop/support/report-damage/ which can be used to report problems with their equipment.

I wasnt able to locate any information on the Vodafone or NBN pages. Suggest you try contacting them through their regular contact pages on their websites.

I’m sure there are other telcos ive missed. Happy to update this list if you have information to share.
