Raspberry Pi WiFi Problems

Knowing that I’d be travelling to Bali, I naturally brought my laptop with me but decided to also include my Raspberry Pi 400 so that I could test it out using the villa’s television set as a monitor. The set up for WiFi is that you first connect to a local IP address and, once connected, you then log in using the supplied user name and password. This is the same as what happens at Starbucks and McDonalds back in Jakarta.

There was no problem connecting with the laptop via the full fledged Chrome browser that is running under Mint Linux but the Raspberry Pi, running the default operating system, struggled mightily. The problem seems to be with the browsers. I tried both Chromium and Firefox ESR (which is not the full-fledged version of the browser) and each had problems with security. What should happen is that a login screen pops up and you can enter the user name and password. This did happen initially but then the connection dropped and I wasn’t able to get that login screen to come up again.

Setting up my iPhone as a hotspot, I was able to connect the Internet without any problems because all that’s required is the password, there is no intermediate step as with the villa’s WiFi. I’ve tinkered around and there’s no obvious solution: Firefox ESR and Chromium just aren’t keen on connecting to what they see as an insecure Internet connection. I don’t travel much these days and so this is not a deal breaker for me. When I return home to Jakarta, my Raspberry Pi will be working fine again but, for someone who spends a good deal of time on the road and wants to make use of hotel WiFi, this would be a major problem.

From Logging to Blogging

A blog is of course a contraction of web and blog and my history of blogging dates back to 2006 when I started my first blog on the then very new blogging platform called Blogger, courtesy of Google. I posted intermittently over the years but only took up serious blogging after I retired in the middle of 2015. However, my history of “logging” or writing on paper rather than electronic media goes back to when I was about ten years old.

At that time I acquired a small five year diary with a very small amount of space for each day, allowing for the entry of about the same number of words as Twitter allows today. I certainly didn’t “tweet” every day but I did make sporadic entries for a couple of years. I remember getting quite upset when I discovered that my mother had been reading it! That diary is long gone now, although I did still have it in my possession for over thirty years. However, I do still have in my possession a journal that I began in mid-1972 at the age of 23 and that is now fifty years old.

Here is the front cover:

It was the dust cover of my copy of Herman Hesse’s “The Glass Bead Game” (Das Glasperlenspiel) or Magister Ludi (Master of the Game) as it is also referred to. The physical book is long gone but I have an electronic version in my Calibre library. It’s interesting that there appears to be a computer of sorts, although it could be just a depiction of television that was actually around when Hesse wrote the book. To quote from Wikipedia, the fount of all knowledge:

The Glass Bead Game (German: Das Glasperlenspielpronounced [das ˈɡlaːspɛʁlənˌʃpiːl] (listen)) is the last full-length novel by the German author Hermann Hesse. It was begun in 1931 in Switzerland, where it was published in 1943 after being rejected for publication in Germany due to Hesse’s anti-Fascist views.[1] In 1946, Hesse won the Nobel Prize in Literature. In honoring him in its Award Ceremony Speech, the Swedish Academy said that the novel “occupies a special position” in Hesse’s work.

I was quite fond of Hesse’s novels at the time and read quite a few of them. The inside cover of my journal features a photograph of my beloved William Blake’s “Death on a Pale Horse”.

I took a photograph of the first page of this journal, not because the profundity of its content, but just to be reminded of my style of writing at the time.

I actually experimented with my iPhone’s speech to text capabilities and this is how it rendered the page following my slow and deliberate recitation ( I read a little beyond the first page):

It was thought-provoking to say the least, tilting one out of the role to frequent complacency and threatening to topple the whole edifice of half by scientific theories and straight out prejudices that one inevitably accumulates in 23 years of life. The immediate reaction, the scientific reflection might call it, with skepticism, a healthy attitude of mind admittedly, but one which must be tempered with a readiness to look critically at what has been presented without projecting it out of hand. Was not too many years ago that it was scientific fact that man who developed from a boreal apes he descended from the trees to the planes and, in the struggle for survival, a species emerged which evolved, and the course of time, to present demand. Yet in the descent of woman, a woman challenges this idea by claiming our anthropoid cousins evolve not on the planes but by the seashore. How easily to archaeologists past of many of the wonders of the New World as well as the Sphinx in the pyramids, that really does fly explanation in terms of the view we have today of man’s evolution from primitive savagery. And a long-term Zürich for Deneken to propose a radical new interpretation of the past, visitors from another world. Perhaps. The point is the traditional scientific theories, which I’ve gained nearly the status of facts, are being challenged. It is so easy to have a preconceived view of things and make the facts fit into that view. Even if the fax or scan, in the case of the fossil evidence to suggest man involved on the plains, the assumption is there that the theory is incontrovertibly correct, only the facts, which will verify the theory, are awaiting discovery.

Here is the corrected text. The speech to text converter hasn’t done too bad a job at all.

It was thought-provoking to say the least, jolting me out of that all too frequent complacency and threatening to topple the whole edifice of half-baked scientific theories and straight-out prejudices that one inevitably accumulates in 23 years of life. The immediate reaction, the scientific reflex you might call it, was skepticism – a healthy attitude of mind admittedly – but one which must be tempered with a readiness to look critically at what has been presented without rejecting it out of hand. It was not too many years ago that it was scientific fact that man had developed from arboreal apes who descended from the trees to the plains and, in the struggle for survival, a species emerged which evolved, and the course of time, to present-day man. Yet in “The Descent of Woman”, a woman challenges this idea by claiming our anthropoid cousins evolve not on the plains but by the seashore. How easily too archaeologists passed off many of the wonders of the New World as well as the Sphinx in the Pyramids, that really do defy explanation in terms of the view we have today of man’s evolution from primitive savagery. And along comes Erich Von Daniken to propose a radical new interpretation of the past, visitors from another world. Perhaps. The point is the traditional scientific theories, which have gained nearly the status of facts, are being challenged. It is so easy to have a preconceived view of things and make the facts fit into that view. Even if the facts are scant, in the case of the fossil evidence to suggest man involved on the plains, the assumption is there that the theory is incontrovertibly correct, only the facts, which will verify the theory, are awaiting discovery.

It’s amusing to read back now over what I was reading then. Here is a summary of what the “The Descent of Woman” is about:

A pioneering work, the first to argue for the equal role of women in human evolution. On its first publication in 1972 it became a rallying-point for feminism and changed the terminology of anthropologists forever. It remains a key text in feminist history, as well as an extension to the author’s Aquatic Ape Hypothesis, which is gaining more academic support each year. Starting with her demolition of the Biblical myth that woman was an afterthought to the creation of man, Elaine Morgan rewrites human history and evolution.

Her theory never gained any traction among anthropologists. She died in 2013, having been born in 1920. Here is an interesting extract from Wikipedia:

Morgan read science books, which were from a library in the Welsh town Mountain Ash, but she did not agree with how those books presented human evolution due to the implication that things happened for the benefit of male hunters and that they stated nothing about protecting children. In 1972, Morgan began writing The Descent of Woman by focusing on the aquatic ape hypothesis which was coined in 1960 by marine biologist Alister Hardy. Hardy’s theory was that ancestors of humans existed during the Pliocene epoch within a forming Africa that was experiencing drought, as hairy four-legged organisms that could not communicate, but left the time period as hairless bipedal organisms. Hardy’s theory also stated that apes gained aquatic adaptations when they were stuck on an island that now circles Ethiopia, which would account for how humans are different from other primates such as how they can wade in water and become buoyant in water. It is her first book. Morgan stated, “I wanted it to be popular with ordinary people, that’s why I tried to make it light. People are funny, sex is funny”. Morgan became aware of the aquatic ape theory by reading The Naked Ape by Desmond Morris. Despite Hardy’s theory not being taken seriously within the scientific community, Morgan believed that the aquatic ape theory was the needed answer to human evolution and wondered why no one had told her about it. She asked Hardy if she could use his theory and after she received an approval from him, Morgan gave the manuscript to her agent. Morgan admitted in 2003 that the book “was a thoroughly unscientific romp riddled with errors and convenient conclusions”.

As for Von Daniken, he was a colourful character back then and his books were very popular. I even remember attending a talk he gave in Brisbane, although I can’t recall what year it was. It may have been the late 60s. Believe it or not, he’s still alive at the time of this post and is aged 87. Again Wikipedia has this to say about him:

Erich Anton Paul von Däniken (/ˈɛrɪk fɒn ˈdɛnɪkɪn/German: [ˈeːrɪç fɔn ˈdɛːnɪkən]; born 14 April 1935) is a Swiss author of several books which make claims about extraterrestrial influences on early human culture, including the best-selling Chariots of the Gods?, published in 1968. Von Däniken is one of the main figures responsible for popularizing the “paleo-contact” and ancient astronauts hypotheses. The ideas put forth in his books are rejected by virtually all scientists and academics, who categorize his work as pseudohistorypseudoarchaeology, and pseudoscience. Early in his career, he was convicted and served time for several counts of fraud or embezzlement, and wrote one of his books in prison. Von Däniken later became a co-founder of the Archaeology, Astronautics and SETI Research Association (AAS RA). He designed Mystery Park (now known as Jungfrau Park), a theme park located in Interlaken, Switzerland, that opened in May 2003.

Here is a photo of him from 2017:

I may transcribe more from journal later on. It’s only about 36 pages, mostly text but with a few diagrams. During the early 80’s and right through to 1993, I filled two thick quarto-sized journals with my scribbling. Unfortunately, before I went overseas, I decided to burn them because they were very personal and I didn’t want anybody reading them. It’s very sad to think about their destruction now. I should have thought of some way of preserving them, even burying them perhaps. Anyway, they’re gone now and there’s nothing to be done about it. Those logging days are long gone and there are certainly more blogging days yet to come.

Blogger to WordPress

Copied from my blog on voodooguru.net using the same title.

I’ve really only used Blogger as my blogging platform since I began blogging in 2006. I did have a brief flirtation with WordPress when creating a Staying Healthy on wordpress.com but I was never comfortable with it and ended up continuing it on Blogger. As I wrote at the time:

I’ve had enough of this platform and its frustrations. I’m moving to Blogger where all my other blogs are anyway. The new address is https://voodooguru1949.blogspot.com/ with the same title for the blog, namely Staying Healthy. I’ll eventually link back to the previous posts on wordpress from my new blog or maybe I can export them. We’ll see.

WordPress was unfamiliar to me at the time and I had gotten so used to Blogger that I couldn’t be bothered coming to terms with the new interface. At that time (August 28th 2020), it hadn’t occurred to me that I could have exported the WordPress blog to Blogger. I’m now realising how relatively easy it is to export and import entire blogs from one platform to another, and to back up entire blogs, using the xml file format.

On this site, there is a simple and straightforward guide on how to move an entire blog from Blogger to WordPress. I’m not sure that I really want to do that but it’s good to know that it’s possible. I’m really still coming to terms with this new WordPress blog and what I want to do with it. I’m happy that I’ve created categories in this blog that correspond to my blogs on Blogger. These categories are:

  • Mathematical Meanderings
  • Mystical Meanderings
  • Astrological Meanderings
  • Pedagogical Posturing
  • Alternative Media
  • Staying Healthy

At this point, I’m inclining to simply continuing my former blogs on the single WordPress blog, differentiating them by the use of the above categories. As I described in my previous blog post, I can export individual WordPress posts to my various blogs on Blogger (should I choose to do so). It’s good to know that I can mothball all these blogs by backing them up in xml file format and saving them on Google Drive and a local computer.

The quality of my posts on Blogger have been variable over the years. Most have been mediocre, a few downright dumb and few of high quality (in my opinion). It would be interesting to revisit my earlier blogs and evaluate them in terms of the current world situation. My blogs have never been about garnering readership. I enjoy writing and expressing my thoughts “on paper”. My electronic blogging may have started in 2006 but I was committing my thoughts to paper long before this. Perhaps this history could be the material for a future post.

WordPress to Blogger

Copied from my WordPress blog on voodooguru.net under the same title.

I have my various blogs on Blogger, some of which date back to 2006, but I only seriously started blogging when I retired in the middle of 2015. I am in a dilemma whether to keep blogging on that platform or shift to WordPress. Anything I post my voodooguru.net website will only survive as long as I keep paying the annual fee for domain name and web hosting.

There is perhaps a solution in the form of a WordPress plugin called “Export to Blogger” that boasts:

With this WordPress plugin, you can easily export WordPress data to Blogger(Blogspot).No need to use software and convert by yourself anymore! This plugin exports dedicated xml files directly, so what you need is just import it to Blogger. Source.

The instructions are straightforward enough:

  1. Upload directory export-to-blogger to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.
  3. Go to Settings -> Export to Blogger to export xml.

There is a website that can be referred to if I have any problems. I plan to do this and then test it out. If it works, then what I may do is to post to this blog but then export to the relevant blog on Blogger. That way I still have the posts on Blogger should I decide to stop using bluehost in the future.

Second Attempt

Copied from my WordPress blog on voodooguru.net under the same title.

I’m going to try to create some mathematical equations using the various LaTeX plugins that are available. This is my second attempt. Here goes:$$ \zeta(2)= \sum_{k=1}^{\infty} \frac{1}{k^2}=\frac{\pi^2}{6} $$As can be seen, I was successful this time after overcoming two problems. The first involved the use of a backward slash \ when a forward slash / was required in the LaTeX delimiters for WP-KaTeX. LaTeX always uses the backward slash and I had gotten very used to it, hence I was led into error. The other problem is that the equation is displayed in black and I have a black background as my theme. The result was that the equation was invisible! Changing the text to white and the background to black fixed the problem. I’m happy to have solved this problem. There is a little too much space above and below the text for my liking but the overall look is quite good, especially in the mobile display.

First Impressions

Copied from my blog on voodooguru.net under the same title.

I’ve only just begun to create the site on which this blog is appearing so there’s more to come as I familiarise myself with its inner workings. I made an attempt to insert some mathematical equations. using a KaTeX plugin, documentation for which can be found here. I did get single line equations working for a while but now nothing works.

I’m gradually getting my head around things. I was hoping to set up a number of blogs on this site and that is possible, although not at all straightforward. The site builder default is one blog only. For the time being I think it’s best to simply link to my Blogger blogs and continue creating blog posts on that platform. I can also link to other sites so that this site acts as a coordinating centre for my various Internet activities.

The photo shows a Raspberry Pi 400 with two monitors connected. It’s not my Pi (I only have one monitor connected) but it demonstrates the impressive capabilities of this little keyboard computer which I purchased about a week ago now.

Returning to my LaTeX problems, I’ve tried three different plugins: WP-KaTeX, KaTeX and QuickLaTeX and none of them work. It amazes me that there is such lack of support for LaTeX from the most popular blogging platform on the planet. Blogger may be out of fashion nowadays as a blogging platform but I’ve never had any problem inserting LaTeX into the posts on my mathematical blog.
