This will probably be one I'll get a lot of comments on, but I've looked at the marketing proposition of HPR in light of some of the challenges we face. To prevent us dipping into the reserve queue and seeing a slow but steady decline in both audience and hosts.. Maybe its time to give HPR a bit of a makeover.

I will talk about information feeds from web sites delivered to my computer device. I use the term feeds and by that I mean both RSS feeds and Atom feeds, the two feed protocols which are very similar.
I believe it is very likely you as listener to Hacker Public Radio know about feeds. Not unlikely you even know the technical details far better than I do.
Nowadays many of us use feeds very often without thinking of them as feeds, when we subscribe to podcasts.
But feeds have been around for many years. Back in the days, I used feeds for websites I was interested in. But somehow I forgot about it and web browsers stopped to support feed subscriptions.
A year or two ago I started my new journey into feeds. Although it is not so much talk about feeds nowadays, very many web sites have support for feed subscriptions.
To start, at my own personal web site (https://www.hemrin.com/) many of the pages have feeds, typically those that are blog-like pages, and you can subscribe to several feeds on my site.
From Hacker Public Radio I subscribe to a feed for all show comments. So when you write a comment regarding my show today, I will get notified in my feed manager.
I primarily use Thunderbird to manage my feeds. I do not need my feeds to be synced to other devices. I use Thunderbird daily for e-mails and it is therefore very practical and natural for me to use it also for feeds. In addition I use the Feeder app on my Android-based phone for some feeds.
I do not use feeds for web sites I anyway will visit often or that have a lot of news. I would be overwhelmed of feeds. Instead I use feeds for web sites which are not updated so frequently but are sites I want to keep an eye on. But some are updated daily, like from the parliament.
In some cases, feeds are an alternative to subscribe to e-mail notifications and e-mail newsletters.
The beauty with feeds is that I am in charge and without giving out e-mail or anything - the site owner do not know I subscribe. Subscription starts so simple as I type the feed-url into my Thunderbird feed manager. And when I want to end a subscription, I simply delete it.
Furthermore I subscribe to Status pages. I get notifications for example from my internet service provider for their planned and unplanned maintenance.
Several authorities have interesting feeds.
I have feeds from some companies and organizations.
I have feeds from many software developers, for example Thunderbird and Linux Mint.
I have feeds from some journalists and politicians and alike.
I have feeds from persons with competence in various areas I am interested in. And other persons who are interesting for the persons they are and their thoughts.
So, this show is to tell you that I have rediscovered feeds and found them useful for me. Maybe you already use feeds. Maybe this show will inspire you to have a look into feeds as a useful tool for your personal or professional life.

I have been struggling with my body weight since I was 35, and I’m
now 60.
I know that not all listeners are familiar with the kilogram as unit of
measurement, but we can use the BMI (Body Mass Index) formula to discuss
this. It should be somewhere between 22 and 25 and mine has been 33 for
a long time. A very long time. No matter what I tried.
Yes, I tried some diets but they only work if you keep doing them. So
if something does not become normal or easy than at some inevitable
point you will stop and gain weight again.
Yes, they talk about changing your life style but any change that is too
drastic is bound to fail in the end.
And then recently I read this book. This absolutely changed my life and that is why I am so motivated to tell you all about it.
Book obesity code, Jason Fung, a Canadian nephrologist (kidney
specialist).
He is also a functional medicine advocate who promotes a
low-carbohydrate high-fat diet and intermittent fasting. But we come
back to that later.
Not another diet hype. That is an industry on its own.
This is scientific stuff. With lots of links to research papers.
With large groups and thoroughly peer reviewed.
And this does not mean that this story is for everyone.
There exist other medical reasons why people gain weight.
But, assuming most people start out in life being healthy, then most
people gaining weight are not ill.
So, if you gain weight, consult your doctor first to rule out any
medical reasons.
Jason Fung noticed that practice didn't match with theory.
Everybody who is given insulin gains weight.
Even diabetes type 2 people.
There are even several scientific studies that proves this. Give people
insulin and they will gain weight.
So what if insulin is the culprit for gaining weight?
Insulin is a hormone. Its job is to send signals through the body.
Its use is to allow body cells to absorb nutrients in the blood
stream.
Every time you eat the insulin peaks and subsides normally three times a day.
Body process called gluconeogenesis. Making fat in the liver for one day storage.
If you eat the body makes insulin. That is normal.
If you eat more, the body makes more insulin.
Body cells adjust to the higher level and become tone deaf to insulin:
Insulin resistant.
This means next time the insulin level needs to be higher.
And higher levels of insulin mean you will gain weight.
If you eat sugar, it is so easy to break down that it goes immediately into storage, e.g. body fat.
The thing is, wheat is chemically a long string of sugars. So the body will break it down into sugar and send that too to storage.
And almost any food we buy these days contains sugar.
Except unprocessed foods like vegetables.
How to lose weight? Well, the body needs to access the fat in storage. So we need to extend not eating until the liver has run dry of the daily dose of liver fat.
This is very easy. Just extend the daily period that you do not
eat.
When do you not eat? When you sleep. So, skip breakfast. The name says
it all, you are breaking your fast.
Drink some coffee (no sugar of course), or tea, or water and try to start eating later in the day.
And another word for not eating is fasting. But it is a voluntary fast!
So I tried this for one day. Skip breakfast and try to eat it at noon. I mean, what could possibly go wrong, right? The next day I had lost some weight. And it was sooo easy! I could say 300 grams but again, your mileage may vary or you have no clue what one gram is, let alone 300. But that is not the point. The point is that I lost weight! And to me this has been super easy.
So the solution turns out to be:
Which brings me to food categories.
Average digestion times of
How has all this theory changed my life and diet?
Since I started 2 month ago I have on average lost 4 kilograms. It could have been more but then there’s the occasional dinner with friends and what is bad, but soo good, is unavoidable.
So, some other stuff that is good to know:
What’s that about exercising?
What’s with the calories in are calories out? Studies have proven that this is a false claim. It just doesn't work that way.
What about stress. Well, it turns out that stress leads to heightened levels of the hormones adrenaline and cortisol. And when cortisol rises, so too does the insulin levels in your body. So, this simply means that stress will lead to weight gain.
Can I simply drink diet sodas. Well, bummer there, because although it diet sodas do not contain calories nor sugars, they will result in a rise in your insulin level, so they are not good for loosing weight.

This is the start of a short series about the JSON data format, and how
the command-line tool jq
can be used to process such data. The plan is to make an open series to
which others may contribute their own experiences using this tool.
The jq command is described on the GitHub page as follows:
jq is a lightweight and flexible command-line JSON processor
…and as:
jqis like sed forJSONdata - you can use it to slice and filter and map and transform structured data with the same ease thatsed,awk,grepand friends let you play with text.
The jq tool is controlled by a programming language
(also referred to as jq), which is very powerful. This
series will mainly deal with this.
To begin we will look at JSON itself. It is defined on
the Wikipedia page
thus:
JSONis an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays (or other serializable values). It is a common data format with diverse uses in electronic data interchange, including that of web applications with servers.
The syntax of JSON is defined by RFC 8259 and by ECMA-404. It is fairly simple in principle but has some complexity.
JSON’s basic data types are (edited from the Wikipedia page):
Number: a signed decimal number that may contain a
fractional part and may use exponential E notation, but cannot include
non-numbers. (NOTE: Unlike what I said in the audio,
there are two values representing non-numbers: 'nan' and
infinity: 'infinity'.
String: a sequence of zero or more Unicode characters. Strings are delimited with double quotation marks and support a backslash escaping syntax.
Boolean: either of the values true or
false
Array: an ordered list of zero or more elements, each of which may be of any type. Arrays use square bracket notation with comma-separated elements.
Object: a collection of name–value pairs where the names
(also called keys) are strings. Objects are delimited with curly
brackets and use commas to separate each pair, while within each pair
the colon ':' character separates the key or name from its
value.
null: an empty value, using the word
null
These are the basic data types listed above (same order):
42
"HPR"
true
["Hacker","Public","Radio"]
{ "firstname": "John", "lastname": "Doe" }
nulljqFrom the Wikipedia page:
jqwas created by Stephen Dolan, and released in October 2012. It was described as being “like sed for JSON data”. Support for regular expressions was added in jq version 1.5.
jqThis tool is available in most of the Linux repositories. For example, on Debian and Debian-based releases you can install it with:
sudo apt install jqSee the download page for the definitive information about available versions.
jqThere is a detailed manual describing the use of the jq
programming language that is used to filter JSON data. It can be found
at https://jqlang.github.io/jq/manual/.
This is a collection of statistics about HPR, in the form of JSON data. We will use this as a moderately detailed example in this episode.
A link to this page may be found on the HPR Calendar page
close to the foot of the page under the heading Workflow.
The link to the JSON statistics is https://hub.hackerpublicradio.org/stats.json.
If you click on this you should see the JSON data formatted for you by your browser. Different browsers represent this in different ways.
You can also collect and display this data from the command line,
using jq of course:
$ curl -s https://hub.hackerpublicradio.org/stats.json | jq '.' | nl -w3 -s' '

38 "unprocessed_comments": 0,
39 "submitted_shows": 0,
40 "shows_in_workflow": 15,
41 "reserve": 27
42 }
43 }The curl utility is useful for collecting information
from links like this. I have used the -s option to ensure
it does not show information about the download process, since it does
this by default. The output is piped to jq which displays
the data in a “pretty printed” form by default, as you see. In this case
I have given jq a minimal filter which causes what it
receives to be printed. The filter is simply '.'. I have
piped the formatted JSON through the nl command to get line
numbers for reference.
The JSON shown here consists of nested JSON objects. The first opening brace and the last at line 43 define the whole thing as a single object.
Briefly, the object contains the following:
stats_generated (line 2)age on lines 3-18; this object
contains two strings and two objectsshows on lines 19-25hosts on line 26slot on lines 27-30workflow on lines 31-34queue on lines 35-42We will look at ways to summarise and reformat such output in a later episode.
I will look at some of the options to jq next time,
though most of them will be revealed as they become relevant.
I will also start looking at jq filters in that
episode.
