 HPR3634: Everything You Always Wanted to Know About PEX Part 05 - PEX and the Single Installer | File Type: audio/mpeg | Duration: Unknown

Everything You Always Wanted to Know About PEX Part 05– PEX and the Single Installer – My PEX installation experience part 2 Pulling PEX Much like pulling thick wire My method Used fish tape to pull mason's line Tied mason's line to PEX about 4 inches from end. Taped above & below with electrical tape Then tied line again closer to the end of PEX. Wrapped again with electrical tape Pull extra Unroll and let it lay straight for 24 hours if "curve memory" is a problem Can be challenging and require an individual installer to go back and forth between the feed point and the pull point. Supporting PEX 1" and smaller PEX must be supported horizontally every 32 inches Vertically, it must be supported at every floor and midway between floors (every 4-6 feet) https://www.pexuniverse.com/providing-proper-support-long-runs-pex-tubing Can be challenging to hold in place until secured Zip ties are your friend! Using a manifold Determine your needs Number of hot and cold outputs Valve type Handled Wrench/key Find a location with Easy access Fairly central to avoid long delays for hot water Limited light exposure Build or buy? Costs Appearance Materials Securing manifold in place Anchor securely Block wall with anchors To wood for spanning wall studs (I don't know why I kept saying "Joist" during the recording) Do not anchor to drywall Insulate from wall if needed Connecting to the main line What to replace and what to use Size matters Plan to include manifold if needed Connecting to water heater Where/how to connect Pipe Unions? Protect from heat Shut-off valve Expansion tank Silicon tape or pipe dope Connecting to endpoints What to keep and what to replace Transition connectors SharkBite Solder Thread Glue Exterior hose taps Reuse or replace? Frost free / anti-siphon Anchor securely Help is better! Turning it on! If using a manifold turn on one section at a time, from the bottom up Open sink valves Ease it on a little at a time Then increase flow Turn off sink tap (Slowly) to let pressure build Keep watching for leaks Coordinate with a partner and communicate (cell phone?) Afterwards Cover any PEX exposed to light Watch for leaks Repair holes Run water daily to flush out bad taste Inspection?

This begins our series about our RV trip by looking at the planning process. We give a suggestion for a nice online course that is not too expensive, and offer some tips on using Google Maps in planning your trip.

 HPR3629: Linux Inlaws S01E59: The Show with Red Pandas Mosaic Killers and Metal Corrosion | File Type: audio/mpeg | Duration: Unknown

In this episode, Martin and Chris interview Eric Rescorla, the CTO of Firefox at Mozilla. After discussing the weather situation in the Kingdom formerly known as the UK, our two aging heros go right into browsers, programming languages, the Mozilla ecosystem and internet history and future alike. This episode again is not for the faint-hearted as none of the gory details are spared: We learn about Chris' t-shirt situation (and how you can kidnap apparel), why Google is so sucessful, data privacy and Internet monetization. Never mind rendering engines. Plus: more Rust marketing (Rebecca Rumbul: Take note :-).

At the end, I am a little disappointed in the performance. One of the cell banks was discharging quicker than the others, but I replaced it and it is much more efficient now.

 HPR3626: The stuff Evil Steve doesn't want you to know S01E06: Use a Password Manager | File Type: audio/mpeg | Duration: Unknown

The stuff Evil Steve doesn't want you to know with Lurking Prion. This is Season 1, Episode 6. Picking up from the last episode, we are now delving in to the security measures we can implement to make ourselves a less attractive for Evil Steve. After implementing 2FA, we should now be setting up and using a password manager. Then we look for and changed passwords involved in known breaches (haveibeenpwned - link in show notes). The show is approximately 19 minutes long.

 HPR3610: DOS Wildcards; File Attributes | File Type: audio/mpeg | Duration: Unknown

For this lesson we are going to fill in a couple of concepts that we will need before we go further with directories. Wildcards can let you look for files and directories without specifying the complete name, and look for items with similar names or file extensions. And file attributes are an important part of file management. Links: https://www.ahuka.com/dos-lessons-for-self-study-purposes/dos-lesson-11-dos-wildcards-file-attributes/

 HPR3609: Linux Inlaws S01E57: Operating System Level Virtualisation and Martin's Faith | File Type: audio/mpeg | Duration: Unknown

In this episode our two ageing heroes take a closer at operating system (OS) level virtualisation. The main different legacy virtualisation technologies like virtual machines (VMs) and this new-fangled approach is that the OS kernel remains the same across virtualisation domains, thus giving the hippsters and other followers of fashion a cheaper and potentially much faster solution than virtualising the kernel and surrounding hawrdware and all the rest of it. Plus more details on Martin's real faith. Don't miss out on this episode if you're interested in any of these...

The astronomer looks out of the window, sees a black sheep standing in a field, and remarks, "How odd. All the sheep in Scotland are black!" "No, no, no!" says the physicist. "Only some Scottish sheep are black." The mathematician rolls his eyes at his companions' muddled thinking and says, "In Scotland, there is at least one sheep, at least one side of which appears to be black from here some of the time."[Stewart, Ian (1995). Concepts of Modern Mathematics.

Saying you don't need to know math to do programming is like saying you don't need to know how to read in order to write. Technically true, but it makes it way easier. Simplifying the statement Knowing math makes programming way easier. Rearrange and problem There are no humans that ever existed or will ever exist that will not find programming easier having a knowledge of maths. I exist. I do not find programming easier despite my knowledge of maths. Q.E.D. other points "Ability to think logically - which is what math is." This assumes that math is the only field where the ability to think logically exists. Math is a subset of logical thinking and not the other way around. I can think of hundreds of occupations that require logical thinking that do not require any maths. It would be difficult to argue this point as it could be argued, as most people are exposed to counting no matter what level of literacy they may have access to. So let us refer to studies with crows that shows that they do think logically - despite any math knowledge.
