Well, since I am sitting at home maintaining a “social distance” I thought I would put down some thoughts about this pandemic and how we will be affected. But a disclaimer to be completely clear: I am not a doctor or a research scientist. I am retired, but I was once a college professor teaching

Statistics

and

Research Methods

. I think this helps me in some way to interpret the information I receive, but when I want authoritative information I look to real doctors, the CDC, and qualified researchers. If you want to know more about what I mean by qualified researchers, you might want to check out my series on interpreting studies:

Scientific and Medical Reports

Problems With Studies

In this episode the HPR Audiobook Club discusses the audiobook Blood Witness by David Hitt

Non-Spoiler Thoughts

This book may or may not be offensive to some. We discuss.

Audio quality was generally good, very few double reads.

Thaj is annoyed by the transition sound.

We generally enjoyed the theme music.

We discuss the characters that we found the most interesting.

Lyle apologizes for being unintentionally offensive.

How do vampires work in this book anyways ?

Beverage Reviews

As usual, the HPR AudioBook Club took some time to review the beverages that each of us were drinking during the episode

Thaj: Water, and a bit of something different. Thaj has had a rough week so he treated himself to Daelmans Wafers

x1101: Redhook Longhammer IPA

pokey: Pokey’s beverage in this episode is Twisted Cabernet Savaugnon.

FiftyOneFifty: Mike’s Hard Smashed Apple Ale

Things We talked about

Pokey thinks the ending is not strong.

He also finds some plot holes.

There is a big door for a sequel.

The logistics of becoming a vampire.

Why "Twilight" sucks.

How the characters react to becoming a vampire.

The book wasn’t as graphic as we anticipated.

We introduce… OneFiftyOneFifty!

Fire!!!

Sparks vs. allsparks

Link in the shownotes…or not.

Do you need a "good person" to cheer on in a story to enjoy it?

Edict Zero:FIS

The Lab Rats - Devil’s Train

OK, so we gave up on the book and just talked about games.

Feedback

Thank you very much for listening to this episode of the HPR AudioBookClub. We had a great time recording this show, and we hope you enjoyed it as well. We also hope you’ll consider joining us next time we record a new episode. Please leave a few words in the episode’s comment section.

As always; remember to visit the HPR contribution page HPR could really use your help right now.

Sincerely, The HPR Audiobook Club

P.S. Some people really like finding mistakes. For their enjoyment, we always include a few.

Locating computers on a network

Sometimes you may wish to locate a device on your network. It might be to find rogue devices, or to locate a new device be that a printer, an Internet of Things light bulb, or whatever. In my case I was trying to track down a RaspberryPi. Raspbian now lists the IP Addresses assigned to it when it first starts, but that requires a monitor to be connected.

Locating using your router.

This is by far the easiest way to find a new device but it is also the most manual. If you have access to the (WiFi) Router/DHCP server on your network then this should be a matter of logging in and getting the address from the menu area probably called Network or LAN or something like that. So first list all the computers that are on the network. Then turn on your pi, and see if a new one has joined. If you're lucky it may even be labeled Raspberry Pi Foundation.

In my case I want to locate these devices automatically using a script. So below we will explore some ways that you can approach the problem of locating devices on your network. All of them rely on trying to find the mapping between an Ethernet MAC Address, and a IP Address. It will help to understand a little about how Ethernet works. This is a nice short overview, How does Ethernet work? (animated) by Janos Pasztor

ARP

I don't know the network device you will be using so I'd like to share a few ways of doing this using the ARP protocol. This provides a mapping between a device's permanent MAC address and their, often temporarily, assigned IP address.

When your computer 192.168.1.1 wants to talk to another device it will need to know the Ethernet MAC address of the other device. Let's assume it wants to connect to the local printer 192.168.1.2 that is on the same network, and it knows its IP Address. If your computer has already heard the printer communicate on the network, it will have already added the printer's IP address and MAC Address to its so called ARP table. Over time older entries will be removed from this table either because they are too old, or there were too many entries.

Linux has a command called arp which will show you a list of the IP addresses mapped to the MAC/HWaddress address.

# arp -n

Address HWtype HWaddress Flags Mask Iface

192.168.1.254 ether ff:ee:dd:cc:bb:aa C eno1

192.168.1.2 ether 00:11:22:33:44:55 C eno1

192.168.1.1 ether 00:aa:bb:cc:dd:ee C eno1

From a Internet Protocol (IP) point of view all your devices in your house are probably in the same Subnet(work). But what if you need to communicate outside your network? For example to ping a well known server 8.8.8.8 to check if you have an Internet Connection. The IP settings also include a Default gateway to send all traffic not intended for the local network.

Finding the Default gateway

Your computer will have many IP Addresses configured but it's a good bet that the network you and your new pi are on is the same

This is Linux Inlaws, a series on free and open source software, black humour, the revolution and freedom in general (this includes ideas and software) and generally having fun.

Linux Inlaws - a podcast about on topics around free and open source software, any associated contraband, communism / the revolution in general and whatever else fancies your tickle.

Please note that this and other episodes may contain strong language, offensive humor and other certainly not politically correct language - you have been warned (our parents insisted on this disclaimer - happy mum?). Thus the content is not suitable for consumption in the workplace (especially when played back on a speaker in an open plan office or similar environments), any minors under the age of 35 or any pets including fluffy little killer bunnies, your trusty guide dog (unless on speed) and cute t-rexes or other associated dinosaurs.

In this show the lads Martin and Chris speak about the legacy, its name and also introduce Tech Support from the Dark Side, a new hotline helping politicians and other users in need of computer support to cope with reality.

Some musings about what computers taught me about reality and perception.

In some countries, people seem to be legitimately concerned about the availability of toilet paper. This episode offers alternatives to toilet paper in the hope of relieving people of additional stress around hygiene.

This is not a joke episode and contains no offensive language, but it is about a potentially sensitive subject, so it has been marked explicit as a precaution.

The GDPR (General Data Protection Regulation) was enacted by the European Community in 2016, and began to be enforced in 2018. Since this covers a large segment of the Internet users, and other jurisdictions are looking at similar legislation this talk is a timely look at what is required and how Open Source Software can meet the legal requirements. https://www.zwilnik.com/?page_id=1096
