Introduction

Two HPR hosts based in Edinburgh got together over Mumble to have a chat during the COVID-19 lockdown.

• MrX
• Dave Morriss

Apology

Dave’s sound was a bit distorted in this recording. Having had recent problems using the Zoom recorder as a microphone, this time the in-built microphone was resorted to, with even worse results it turned out. See the Sound processing section below if you want to know more.

Notes

Some of the topics we discussed

• Locations for recording. Ambient noises.
• WiFi versus ethernet. Dave has a 5-port switch on his dining table (not 8-port).
• ADSL routers
• Linksys NSLU2 "SLUG"
• SheevaPlug
• CUPS - printing and scanning with old non-networked printers
• Legacy computing experiences:
  • Diablo exchangeable disks
  • Line printers. Fan-fold 132 column paper
  • Punched card experiences. Card sequence numbers. Card sorters.
  • Checking disks for warped platters
  • Magnetic tapes; recovering from damage.
• 8-track tapes
• Museum of Communication, Fife
  • Strowger switch electromechanical stepping switch telephone exchange system

• Museum of Communication, Burntisland, Fife

Sound processing

The recording was made in multichannel mode in anticipation of problems. The distorted channel was processed by using the Clip Fix effect in Audacity, which didn’t seem to change much except reduce the sound level. It was also necessary to find and remove sounds produced by the push to talk key presses. Removal meant replacing these sounds by silence so the two channels would not get out of step. After this the two channels were merged together and silences truncated.

Lessons learned: don’t use a built-in microphone if you can help it!

This conversation took almost an hour, so I split it into two shows:

• Part 1 talks mostly about the RFC itself, what it means and why.
• Part 2 goes into personal experiences with the RFC and with syndication in general, in particular in the context of web comics. This is part 1.

The why

When serving most RSS/Atom feed readers today, you have to choose: Do you make a complete feed with all the things you ever published, or do you make a shorter feed with just the latest entries?

This is a trade-off with pros and cons, and it seems like a trade-off you have to make, but a solution to let your Atom feed have the cake and eat it too existed already 13 years ago, if only any of our feed readers would adhere to it: RFC 5005, Feed Paging and Archiving

The what

https://tools.ietf.org/html/rfc5005 was published in September 2007

• The XML namespace for RFC 5005 elements is http://purl.org/syndication/history/1.0, aliased as fh below.
• Section 2 defines the complete feed: It is one document (Atom file) that contains the entire set the feed describes. The document is marked with an fh:complete element.
• Section 3 defines the paged feed: It is a series of documents connected with Atom link elements with rel set to the link relations first, last, previous or next.
• Section 4 defines the archived feed: It has a subscription document that may change at any time, and a series of archive documents that are expected to have stable contents and URIs. The link relations defined are current, prev-archive and next-archive. The semantics are clearer: prev-archive refers to previously published entries, and because the contents are stable you can stop when you see a URI to a document you already have. Archive documents are marked with the fh:archive element.

The who

In this show I’m talking to:

fluffy

• Federated social web:
  https://queer.party/@fluffy
• Writes and makes things in several creative fields:
  https://beesbuzz.biz/
• Publ is like a static site generator, but dynamic. It produces RFC 5005 archive feeds, of course:
  http://publ.beesbuzz.biz/
• Thoughts on ephemeral content vs content worth archiving and how they relate to protocols:
  https://beesbuzz.biz/blog/5709-Keeping-it-personal

Jamey

• Federated social web:
  https://toot.cat/@jamey
• Blog:
  http://minilop.net/
• Made a prototype full-history reader that follows RFC 5005 links:
  http://reader.minilop.net/
• Made a webcomic reader mostly mentioned in Part 2:
  https://www.comic-rocket.com/
• Made a WordPress plugin implementing RFC 5005:
  https://github.com/jameysharp/wp-fullhistory
• Made an RFC 5005 archive feed synthesizer for sites with a predictable post frequency and URL structure:
  https://github.com/jameysharp/predictable/
  Hosted at https://fh.minilop.net/
• Was on HPR 9 years ago, talking about Xorg!
  http://hackerpublicradio.org/eps.php?id=0825

Conversation notes

• Google Reader was terminated 2013-07-01, all subscription data permanently gone on 2013-07-15:
  https://www.google.com/reader/about/
• Mastodon had Atom feeds with paging, but the feeds went away when OStatus went away:
  https://github.com/tootsuite/mastodon/pull/11247
• HTML4 does indeed define the HTML link relations:
  https://www.w3.org/TR/html4/types.html#h-6.12
  It has prev rather than the previous of RFC 5005, but mentions that some browsers support previous as an alias.
• HTML5 also defines the HTML link relations:
  https://html.spec.whatwg.org/multipage/links.html
  Here previous is a lower-case must for historical reasons.
• IANA manages the Registry of Link Relations:
  https://www.iana.org/assignments/link-relations/link-relations.xhtml
  It references RFC 5005 for the Section 4 relations, but not the Section 3 ones.
• RFC 5005 singles out its own Section 3 (Paged Feeds) as the best-effort, loose, discouraged model.
  • Section 3:

    Therefore, clients SHOULD NOT present paged feeds as coherent or complete, or make assumptions to that effect.

  • Section 4:

    Unlike paged feeds, archived feeds enable clients to do this without losing entries.

• I’m confused about it in the show, but the RFC is clear that an archived feed has one dynamic subscription document, which points to a chain of immutable archive documents.
• Back in 2002, Aaron Swartz published his joke MIME-header-based RSS 3:
  http://www.aaronsw.com/weblog/000574
  The cultural context at the time and the rivalry between RSS 0.91+, RSS 1.0, RSS 2.0 and Atom deserves a show of its own.

In episode 3057 I talked about formal verification of software and forgot to mention why one would want to do it. This episode hopefully answers to that.

While formal verification is powerful tool, it’s also rather cumbersome and slow to use. In some cases you’re better off with traditional ways of testing.

This is an update to my earlier show to pull together what we know about the Coronavirus on this date, and what measures we can take. It focuses on the lack of solid information at this point and suggests a prudent course to stay safe. https://www.palain.com/health-topics/coronavirus-update-20200507/

Coronavirus Update 20200507

The coronavirus pandemic is continuing throughout most of the world, and I wanted to put down some observations on where we stand today. First, note that I put the date in the title. This is because the situation in some ways changes day-by-day, even though there are continuities. That makes it a dangerous place to be because it is human nature to look for the latest news and jump on it if it looks good. And that is a prime mistake because we do not in fact know enough at this point to be confident in these news reports. I would refer you to my earlier essay, Scientific and Medical Reports, which is highly relevant right now. While I could not have predicted this pandemic when I wrote it, it contains basic principles that are always relevant.

The nature of the press is that it is like the carnivorous plant in the movie Little Shop of Horrors, always crying "Feed Me!" And of course we are all interested if not to say anxious for any news on the course of this disease and where it is taking us. What this means is that you will see a unstoppable stream of news stories touting the latest study on one or another aspect of this. Add in the desire of politicians to spin things to their advantage, and you have a recipe for disaster. To keep sane, remember a few basic principles:

• One study proves nothing. There are lots of studies, and many of them are one-and-done without having any effect on medical practice. If there is an interesting result, it merely indicates an area for further study.
• Study results are only meaningful when they have withstood peer review and have been replicated by other scientists. This process does produce good results, but only with time. Only in movies do scientists go into the lab and come out 24 hours later with the answer.
• If you really want to know when all of this will end, there are only two answers. It can end very soon with an accompanying loss of life because the virus is still spreading. This is starting to show up in places that ignore the science. Going outside without a mask and carrying on as usual is not brave, it is stupid.
• The other answer is that a gradual relaxation of isolation can happen if it guided by sound science. Unfortunately, as just explained, that sound science is still being sought, and will take time.
• When you see the vast majority of doctors and scientists saying the same thing, that is your best assurance the information is accurate.
• Right now the number one priority is testing, testing, testing.

So, with that background, do we know anything at this point? Yes, we do. But we also have a lot of unanswered questions.

Second Wave?

The first big question is whether there will be a second wave, and this is something that every qualified epidemiologist I have heard from says is guaranteed. And the reason is that a certain "fatigue" sets in with staying in isolation, and at least some people will convince themselves they don’t need to do it. They are wrong, and they will guarantee that second wave. In the 1918 Flu Pandemic, the second wave was far worse than the first wave. And don’t forget there was a third wave in that pandemic until it petered out in 1920. The best thing you can do is keep isolated if at all possible, and follow all of the guidelines:

• Wear a mask if you must go out, such as for groceries.
• Many stores are offering special hours for seniors. If you are one, take advantage.
• After a shopping trip, wash or disinfect items carefully. Remember that soap is all you need to defeat the virus, but use disinfectant wipes when soap is not practical.
• After returning, strip and place all of your clothes in the washer. The detergent should kill any virus that is there.
• Wash your hands with soap frequently.
• Try not to touch your face.
• Maintain at least two meters distance from anyone not in your household when you do go out.
• Try to stay fit. I go for walks in my neighborhood if there aren’t too many others out, and when there is someone else out, I give them a wide separation. I also do gardening in my own yard, and exercise in my home. That won’t prevent you from getting the disease, but it may prevent you from dying of it.

Yeah, this is all of the stuff we have been hearing all along. But annoying as it is, it does work if you do it.

Is the virus mutating?

Yes. In other news, water is wet. Face it, mutation is what organisms do, and that has been true for billions of years. The question you really have is "Is it getting worse?" And right now the answer is "We don’t know." Sorry I can’t give you any more determinative answer, but we are only at the "one study" phase right now, and we are a ways off from the "peer-reviewed, replicated consensus" phase that will resolve this. There are indications that at least this virus does not mutate as much as influenza, but even that may require more study.

Am I Immune?

We would all love to know if we are immune. This requires two big things to give a good answer. First, does having the disease and then recovering give you immunity? And the sad truth is that we don’t know yet. The common cold is a coronavirus, and you never get immunity. Influenza is a virus, and getting it one year provides no immunity the next. And if getting it once does provide immunity, we still need testing to discover this. The number one priority right now in all locations should be testing, testing, testing. That is the prerequisite for doing any decent epidemiology. There was a report (note: one study) out of South Korea that indicated that some people could get the disease twice, but they re-analyzed the data and decided that it might have been false positives. That is the kind of thing that happens when scientists are trying to do a year’s worth of work in few weeks, which is what they are doing.

Is It More Infectious Than We Thought?

Again, very unclear. And even less clear is what this implies. An argument is being made that if the rate of infection is higher, given the number of deaths, that would imply it is less lethal. And that is being used to argue in favor of this not being a big deal, so reopen everything. But to put it in perspective, in the 2017-2018 flu season, which was on the high end of deaths, we had 61 thousand deaths in the U.S. Today, in just over 2 months, we have 75 thousand deaths in the US, and that is with all of the extraordinary measures we put in place to keep people safe. To make an argument that Covid-19 is no more dangerous than the flu is to be criminally stupid at best.

Didn’t They Predict More Deaths?

Why yes, they did. A widely used model in the US is from the Institute for Health Metrics and Evaluation (IHME), at the University of Washington. And they have issued forecasts that ranged from hundreds of thousands of deaths to around 60,000 deaths. Clearly they have no idea what they are doing, right? Not so fast. As the statistician George Box famously said, "All models are wrong but some are useful". In this case you have to factor in two things. One is uncertainty, of course. To forecast how many people will die, it helps to know how many people have died, and this has been subject to fierce debate.

And here it gets difficult, since one argument is over what counts as a Covid-19 death. And since every one of our 50 states has their own health reporting system, there is a wide disparity. One example of this is the idea of "excess deaths". If a given area has a pretty regular death rate for a number of years, and suddenly that death rate jumps 500% in the midst of a pandemic, it is reasonable to suspect those "excess deaths" are a result of the coronavirus. But if those deaths get counted, others will argue that it is inflating the numbers, and that only a positive coronavirus serum test should count. Since each state does this differently, this leads to the odd result that the disease appears more or less lethal depending on your state of residence. And that means politicians have incentive to get the numbers they want.

The other factor complicating things is the phenomenon known as the "self-preventing" prophecy. You see, the initial high estimates tended to be "This is what will happen if you don’t take strong measures", and of course they were very high. And we know that governments like the UK and the US looked at those predictions, and started to take some stronger measures. So after a little bit, new predictions came out that were lower as a result of those measures. And now we are seeing misguided efforts to get people to go out and resume normal life, and as a result the newest forecasts are going up again. This is a feedback loop, in other words.

For the sake of archival, "state of the world" refers to the COVID-19 pandemic.

Many social media apps seem determined to put bells and whistles in every possible place, which is not always in the interest of the user. This talk presents an alternative view which is called “minimally social” which only puts in the features needed by the user. In this case, the main focus is on a simple blogging app. There is also a brief mention of a very technical talk about coding. https://www.zwilnik.com/?page_id=1103

It's high time I submitted a sample episode from Escape Pod, one of the many excellent Podcasts from the Escape Artists. They are a serious platform for the best science fiction out there today.

With so much choice, I can pick a recommendation that I think will be right up HPR's alley, and that is Escape Pod 624: Fandom for Robots released on April 19, 2018 written by Vina Jie-Min Prasad and Narrated by Trendane Sparks.
