Low Traffic Neighbourhoods in UK: Intent and Impact – Colossal Controversy

In 2016, Public Health England released a guide for local authorities to promote active travel as a solution to physical inactivity. Physical inactivity costs the UK billions of pounds a year when its impact on NHS, social care, absence from work caused by illness and other factors are considered. On 23rd May 2020, the UK government announced funding to local authorities in England for active travel schemes and encouraged them to make the changes as soon as possible. As a result, most London councils (by following the guidance by Transport for London) and some other cities in England started introducing modal filters to create Low Traffic Neighbourhoods (LTNs) to access the government funding.

6 Toothpaste Tablet Brands for Complete Zero-waste Living in UK

The hardcore recyclers among us know that the toothpaste tubes are very difficult to recycle. They contain a thin layer of aluminium and multiple types of plastic. The majority of the UK councils don’t accept toothpaste tubes. In the UK, Colgate partnered with TerraCycle so you can drop off Colgate products at a local TerraCycle drop-off location. Unfortunately, TerraCycle isn’t very easy to use as their drop-off points aren’t too close and are usually private homes.

It is best to avoid toothpaste tubes altogether and switch to sustainable toothpaste tablets. Thankfully here in the UK we have quite a few toothpaste tablet brands to choose from. Below are 6 UK based toothpaste tablet brands that offer quick national delivery.

5 Foolproof Pointers to Achieve Perfect Sourdough Bread

Would you like to bake the perfect sourdough bread? Is your bread not getting enough rise? Are you not seeing the ‘ear’ on your bread? This post will get you there!

Pointers

1. Use water to achieve steam

If you’re a home baker you’re unlikely to own an oven with steam functionality. In that case you should put a tray of water in the oven to achieve steam. Steam slows crust from forming and helps bread to rise. You’ll need to take the water tray out mid-way to let the crust go golden brown.

How I passed Certified Kubernetes Administrator exam

I started working with Kubernetes in 2018 (about 3 years ago). In 2019, I successfully migrated a production application into an AWS Elastic Kubernetes Service (EKS) cluster. I’ve been managing that cluster for more than 2 years. All this made me confident that it would be easy for me to pass Certified Kubernetes Administrator (CKA) exam.

Easy Backups to Google Drive on Linux

I’ve recently set up automated backups to Google Drive on my CentOS 7 Linux VPS to protect my blog posts from data loss. I don’t know why it took so long for me to care about backups of my own data. I chose to back up to Google Drive since I already have a Google One plan that has plenty of available storage space.
