MIcro SD Cards

Having bought a 128 GB micro SD card, I could not find an adaptor to insert it into, even though I knew I had some laying around somewhere. In the end, I ended five of them online (the smallest number that could be purchased). Unfortunately, the SD card reader on my laptop doesn't recognise the card and two old USB 2 card readers that I found where also of no use. I'll purchase a USB 3 card reader and hope that does the job.

The reason for my purchase is that I want to store my Calibre e-book library on a storage device other than my hard drive. When my laptop crashed after updating Linux Mint, I lost all the data on my hard drive and even though I had a backup on an external hard drive, it was sadly out of date. It was quite a tedious and slow job to back up the library which is why I procrastinated in doing it. 

The SD card, even with the adaptor, is more compact than a thumb drive and can sit less obtrusively in my USB hub that currently hosts a fan and a dongle for my mouse. There are two slots left. My laptop has two USB 3.0 ports, one hosts my TP-LINK WiFi dongle and the other hosts my USB hub. 

It would be nice to have everything working on my laptop but that it's nearly 11 years old now I can't complain. Currently my Elementary OS that I have installed doesn't recognise the internal WiFi card, the webcam or, seemingly, the SD card reader. Nonetheless, I'm happy with the current performance of the laptop.

WiFi and Elementary OS

Since installing Elementary OS on my 2013 MacBook Pro, I had been using a wired connection and only recently noticed that the operating system was not recognising the wireless card in my laptop. I tried a few suggested solutions online but nothing worked. However, I found an old USB WiFi dongle that simply worked.

I was curious to find out more about this venerable dongle so I asked Gemini:

What can you tell me about the year of manufacture and other details of the TP-LINK USB dongle with identification TL-WN322G+?

Identifying the exact year of manufacture for a specific TP-LINK TL-WN322G+ USB dongle might be challenging due to the lack of individual tracking on each unit. However, I can provide you with some general information about this model and suggest methods to determine its approximate age:

General Information:

  • The TP-LINK TL-WN322G+ is a wireless USB adapter that supports 802.11g Wi-Fi connectivity with speeds up to 54 Mbps. 

  • It was first introduced in 2008, making it a relatively older model compared to newer Wi-Fi standards like 802.11ac and 802.11ax. 

  • It's a budget-friendly option for basic internet connectivity needs and is not ideal for demanding tasks requiring high bandwidth.

Given that our Internet router is pretty ancient that's hardly a problem. I asked the following question:

What WiFi standard came before 802.11ac and 802.11ax?

The WiFi standard that came before 802.11ac is 802.11n, also known as Wi-Fi 4. It was introduced in 2009 and offered significant improvements over its predecessor, 802.11g, in terms of:
  • Speed: Increased maximum data transfer rates of up to 300 Mbps compared to 54 Mbps for 802.11g. 
  • Range: Improved signal range and stability. 
  • Multiple-Input, Multiple-Output (MIMO) technology: Introduced MIMO technology, which utilizes multiple antennas to transmit and receive data simultaneously, further enhancing speed and reliability. 
  • 802.11ac, also known as Wi-Fi 5, came after 802.11n in 2013 and offered even faster speeds (up to 1.3 Gbps), wider channels, and improved beamforming technology for more efficient data transmission. Finally, 802.11ax, or Wi-Fi 6, arrived in 2019, bringing further advancements in speed, efficiency, and capacity to handle the ever-growing demands of modern wireless networks. 

So here I am with my 2013 MacBook Pro and my 2008 WiFi dongle connected to rather dated wireless router. I thought I'd find out more about this router:

What can you tell me about the HUAWEI EchoLife HG8245A wireless router?

The Huawei EchoLife HG8245A is an optical network terminal (ONT), also known as a fiber optic modem router,  designed for home and small office/home office (SOHO) users. It utilizes GPON technology to provide high-speed internet access through fiber optic cables.

Here are some key features of the Huawei EchoLife HG8245A:

  • Supports GPON technology: Delivers fast and reliable internet connectivity through fiber optic cables. 

  • Wi-Fi connectivity: Provides wireless networking capabilities with support for 802.11b/g/n standards, offering speeds of up to 300 Mbps. 

  • Wired connectivity: Includes four Gigabit Ethernet LAN ports for connecting wired devices like computers, game consoles, and smart TVs. 

  • Additional features: It also has one Phone (POTS) port for connecting a landline phone, and one USB 2.0 port for potential future uses.

Here's a table summarizing the specifications of Huawei EchoLife HG8245A:

Feature Specification

  • Technology GPON 

  • Wi-Fi Standard 802.11b/g/n 

  • Wi-Fi Speed Up to 300 Mbps 

  • Ethernet Ports 4 x Gigabit LAN 

  • Phone (POTS) Ports 1 

  • USB Ports 1 x USB 2.0

Overall, the Huawei EchoLife HG8245A is a suitable option for users who require a reliable and basic fiber optic internet connection for home or small office use. However, it's important to note that the Wi-Fi standard it supports (802.11n) is an older standard with limited speeds compared to newer options like Wi-Fi 5 (802.11ac) and Wi-Fi 6 (802.11ax).

If you prioritize high-speed Wi-Fi for activities like online gaming, streaming high-definition videos, or transferring large files, you might want to consider a router that supports newer Wi-Fi standards.

I tried to find out the year of manufacture of this modem:

What year was this wireless router from HUAWEI released?

Unfortunately, I couldn't find a definitive answer about the exact year the Huawei EchoLife HG8245A was first released.

While I looked through various resources including product pages, press releases, and technology news archives, the specific launch date wasn't readily available.

However, based on the information gathered:

The router supports the 802.11n Wi-Fi standard, which was introduced in 2009. This suggests the HG8245A was likely released after 2009, but an exact year is difficult to pinpoint.

It's also helpful to consider the release dates of similar models from Huawei. For instance, the Huawei EchoLife HG8120, a predecessor model, was released in 2008. This might suggest the HG8245A came out sometime after 2008.

Therefore, while I cannot confirm the exact year, it's safe to assume the Huawei EchoLife HG8245A was released sometime after 2009, likely in the early 2010s.

My Maxim

 Once a day

But

Everyday

Ah, a fine maxim that I hope to apply to more of the activities that I tend to neglect. In my Mathematics post today I averred to subject the number associated with my diurnal age to the rules of Conway's Game of Life, once a day but everyday. I might usefully apply this maxim to the my dart throwing. I've already set up an Airtable database to keep track of my "efficiency" as I call it and which I explained in a blog post titled Measuring Dartsmanship. I should also apply it my chess puzzle solving that I wrote about in a blog titled Chess Puzzle in October of 2023. A puzzle solved each day is a sure way to improve my chess abilities or at least arrest their decline.

The maxim can also be applied to physical activities around the house. There are plenty of chores that need doing and it might be helpful to create a list of them so they could be attended to on a more regular basis. As it is, I tend to have bursts of sometimes intense activity followed by long periods of indolence. Getting back to intellectual matters, my failure to master the Indonesian language could be attributed in part to my failure to embrace this maxim. Again, I have bursts of activity followed by inactivity. I was thinking that watching at least one YouTube video each day about the language might be helpful.


Variations on a theme

The activity doesn't have to be the same each day. For example, if I didn't want to solve some chess puzzles then I could play a game of chess instead or study an opening. Similarly with the Indonesian language, there are many activities that could be tried other than watching videos. For instance, Desy was searching for the English word "fold" to describe the activity of folding clothes. I told her the correct word and didn't want to admit that I didn't know the equivalent Indonesian word. The word happens to be "lipat".

"tikar" means "mat"

For example, "Desy folded the clothes" would translate as "Desy melibat bajunya" and "followed clothes" would translate as "pakaian terlibat". There's a similar word "libat" that means "to wrap" and is used figuratively to mean to be involved with or wrapped up in something. For example, "She was involved with a married man "Dia terlibat dengan pria yang sudah menikah". There's even "lihat" that means "to see".

Elementary OS: Initial Impressions

Given that I've just recently install Elementary OS on my 2023 Macbook Pro (see previous post), it seems appropriate to make some initial observations about its functionality. The OS doesn't come with much software installed and my first order of business was to download the Chrome browser which is my browser of choice and upon which I am heavily reliant. That proved relatively painless thanks to Google's clear instructions. The OS has a so-called App Centre but Chrome was not listed there and so was of no help whatsoever.


The App Centre Software Categories

Next I installed my ExpressVPN and once again that was easy enough thanks to their very helpful website. No help of course from the App Centre but typing "torrents" into the search bar of the same brought up Gabut Download Manager that supposedly handles torrent files and I needed that. Happily, the app works fine when I downloaded a test ebook but that's when the awful realisation downed on me that I'd erased my Calibre library of ebooks. For some reason it didn't cross my mind and given that the laptop wouldn't reboot, the library was probably lost anyway. 


Opps! I forgot to keep my eLibrary backed up

I do have a backup of the library but my last back up was quite some time ago so many books have been lost. I got out of the habit of backing up regularly and have paid the price. The library is too large to back up online. Calibre is not listed at the App Centre but I happened to notice a small link that leads to Flathub and a message that apps can be side-loaded from that source. The download was successful. I also noticed that Chrome and a great many other apps are available on Flathub so that's probably the best place to retrieve apps from. 

The native video player opened an AVI file that I'd downloaded but played only audio with no video. However, VLC from Flathub came to the rescue and I had video as well as audio!

Linux Mint Update Catastrophe

When it ain't broke, there's no need to fix it and things were working just fine. I had a certain version of Linux Mint installed on my laptop, I don't even know what version, and I unwisely decided to update. I assumed it would be to the latest version (Virginia 21.3) but instead it was updated to Vanessa (21) and that's when that laptop was definitely broke. The entire hard drive became read only and I couldn't add or delete anything.

I commonly take screenshots and the app worked just fine but I couldn't save the screenshots to the hard drive. I couldn't even open this blog for editing because Blogger needed to save to the hard drive. Checking on the Internet, I found that the problem is well known but a solution is not so easy to find. This is the reason most people use Windows or Mac OS. They don't want to be bothered by annoyances of this sort.

I'm coming to the same point of view. To experience such a basic and catatrophic mishap after an upgrade is unforgiveable. I'll never use Linux Mint again and will now revert to Ubuntu that used to be my Linux distribution of choice. I thought it might be possible to upgrade from Vanessa to Virginia but that's not currently possible for some reason.  Fortunately my trusty Raspberry Pi 400 is working just fine and so I'm able to remain productive and even update this blog.

The wired connection to the Internet has ceased to work on the laptop and the battery is showing a 0% charge, even though it's fully charged. Whoever the brains were behind this upgrade, they need to be fired. While I'm sure I'll get the laptop operational again, I'm not going to make the same mistake again. Once a working OS is installed, that will be it, no more upgrades. As a matter of principle however, I'll never use Linux Mint again and never recommend that anyone else uses it.

Currently I'm downloading Ubuntu 22.04 to the SD card on the Raspberry Pi and my typing freezes intermittently as I'm typing this. So it goes. I guess what I'd like for my forthcoming birthday is an up-to-date mini PC or a more recent laptop, such as an M1 Macbook Air with 16GB of RAM. One can dream, can't one?

Well the Ubuntu download failed due to insufficient disk space so I've opted for the smaller Elementary OS which should fit on the SD card. It should be said that the card in question also holds the Raspberry Pi OS and the computer boots off that card. Google's Gemini recommended this operating system when I put the following question to it:

What is the best Linux-based operating system for a 2013 Macbook Pro with Retina Display? I had been using Linux Mint but when I upgraded the result was a disaster. So don't recommend that please. 

While there isn't a single "best" option, several Linux distributions can work well on your 2013 MacBook Pro with Retina display. The best choice for you will depend on your specific needs and preferences. Here are some options with some considerations:

Distributions with good Retina display support:
  • Elementary OS: Known for its user-friendly interface and polished visuals, which might offer an experience similar to your previous Linux Mint setup. However, keep in mind that it's based on Ubuntu so might have encountered similar upgrade issues.
  • Manjaro KDE: KDE Plasma offers excellent customization options and generally good high-DPI scaling support. However, some users report scaling issues specifically on 2013 MBPs, so checking compatibility beforehand is recommended.
  • Ubuntu: A popular choice with good hardware support and a large community. However, its default Gnome desktop environment may not have the best scaling experience for some users. Look into alternative desktops like KDE Plasma or XFCE on Ubuntu for potentially better results.
Other noteworthy options:
  • Fedora: This distro focuses on cutting-edge features and updates, potentially offering a more modern experience. However, it requires more technical knowledge than some other options.
  • Solus: Emphasizes ease of use and stability, with good high-DPI scaling support. However, it has a smaller community and may have fewer available software packages compared to larger distros.
Well, the bootable USB containing the Elementary OS has been created and it's time to check what files I need to save from the laptop. There won't be many. I keep most of my important files on Google Drive. I'll be surprised if the installation goes smoothly but I remain hopeful.

After shutting down my laptop, I found that it wouldn't reboot and so I had to abandon any attempt at retrieving files. No matter, I'm typing now on my laptop using the Elementary OS that seems to be functioning quite well. The webcam is not operational but that's been the case with all the Linux installations and it's no problem for me because I rarely have cause to use it. Apart from that all seems well. Fingers crossed. 

I'll close this post by reiterating what a complete disaster my attempt at a Linux Mint update was. For a major Linux distributor, this was unforgivable. The upside was that I got a new OS that seems to be functioning as OS's should.

Playing Possum


The Virginia Opossum

I'd heard the term "playing possum" before when I heard it mentioned in a video that I was watching. However, I wouldn't have been able to provide a clear definition of its meaning if somebody asked me so I consulted Bard.

What is meant by the phrase "playing possum" and how did the term arise?

The phrase "playing possum" means pretending to be dead or unconscious in order to deceive someone, typically a predator or opponent. It's often used metaphorically to describe any situation where someone pretends to be incapacitated or uninterested to gain an advantage.

Origin of the phrase:

The term most likely originated from the behavior of the Virginia opossum. When threatened, these marsupials enter a state of tonic immobility, appearing limp and lifeless, with drool dripping from their mouths and eyes closed. This state can last for several minutes, often fooling predators into thinking they've found a dead animal and abandoning their pursuit.

The first recorded use of the phrase "play possum" appears in an 1835 American newspaper article, referencing the opossum's behavior. Over time, the term gained wider usage and transcended its literal meaning to encompass any situation where someone feigns weakness or disinterest to deceive others.

Examples of using "playing possum":

  • The football player pretended to be injured to draw a penalty kick.
  • The company played possum during the negotiations, hoping to get a better deal later.
  • The cat rolled onto its back and played possum, hoping to lure the unsuspecting toy mouse closer.

In conclusion, "playing possum" is a colorful idiom rooted in the fascinating defensive strategy of the Virginia opossum. It serves as a reminder that sometimes, appearances can be deceiving, and pretending to be weak can actually give you the upper hand.

I then asked Bard the following:

Are there other phrases like "playing possum" that also involve the behaviour of a particular animal?

Absolutely! The animal kingdom offers a treasure trove of fascinating behaviors that have inspired colorful idioms and phrases. Here are some examples like "playing possum" that draw on the unique habits of various creatures:

Feigning Weakness:

  • Playing crocodile tears: Pretending to cry to evoke sympathy or manipulate someone, inspired by the crocodile's reputation for shedding fake tears while eating its prey.
  • Crawling into one's shell: Retreating from conflict or withdrawing emotionally, referencing the defensive behavior of turtles and snails.
  • Putting on a sheep's clothing: Appearing harmless or innocent while harboring hidden intentions, drawing on the contrast between the gentle nature of sheep and the predatory tendencies of wolves in disguise.

Strategic Actions:

  • Cunning as a fox: Using cleverness and deceit to achieve one's goals, referencing the fox's reputation for trickery and resourcefulness.
  • Busy as a bee: Working with tireless energy and efficiency, inspired by the constant activity of bees in their hives.
  • Following one's own scent: Being confident and independent, based on the ability of dogs to track scents and navigate without relying on others.

Unusual Traits:

  • Blind as a bat: Lacking awareness or understanding, referencing the nocturnal habits of bats and their reliance on echolocation.
  • Stubborn as a mule: Refusing to budge or change one's mind, based on the mule's reputation for being headstrong and independent.
  • Changeable as a chameleon: Adapting quickly to new situations or changing one's opinion frequently, inspired by the chameleon's ability to shift its skin color.

These are just a few examples, and the list goes on! From the slyness of a fox to the resilience of an ant, the animal kingdom provides a rich source of metaphors and inspiration for colorful language.

Main Focus

I was listening to song by Paul Kelly called "I'm on Your Side" recently when I came across these words in the lyrics:

The trees on the shoreline are all fresh from the rain

The ship on the water is heading for the main

I had to ask myself what was this "main" that the ship was heading towards? I'd heard of the Spanish Main but I realised that I didn't know what that was. So Bard to the rescue:

Main often refers to the open sea, as opposed to sheltered bays or harbors. So, when you say "The ship on the water is heading for the main," it means it's leaving the coast and sailing out into the open ocean.

"Spanish Main" refers to a specific historical region encompassing the Caribbean Sea and the coasts of Central and South America, particularly during the era of Spanish colonization and piracy. 

The word "main" has significance for me because my childhood home was located in a street in Milton, Brisbane, called Mayneview Street. The street often ended up being spelled as Mainview Street because it wasn't realised that the street was named after a person whose surname was Mayne. The error was encouraged because the street running parallel to Mayneview Street was Parkview Street. The former surmounted a hill and so did provide what could be considered the main view over the nearby Lang Park as it was then called and later to be renamed Suncorp Stadium.

I asked Bard for information about who this historical character called Mayne might be:

There is a street in Milton, Brisbane Australia, called "Mayneview Street". Do you have any information about the person called "Mayne" after which the street was named?

Unfortunately, pinpointing the exact "Mayne" who inspired Mayneview Street in Milton, Brisbane, proves a bit tricky. While historical records offer several possibilities, conclusive evidence linking a specific individual to the street name remains elusive. Here's what we can uncover:

Potential Candidates:

John Mayne (1800-1864): This John Mayne was a prominent early settler and businessman in Brisbane. He arrived in the colony in 1842 and quickly established himself as a successful merchant and landowner. Mayne owned considerable property in the Milton area, including land near the present-day Mayneview Street. He also served on the Brisbane Town Council and was a Justice of the Peace.

Charles Mayne (1832-1907): Charles Mayne was the son of John Mayne and followed in his father's footsteps as a successful businessman and politician. He served as a member of the Queensland Legislative Assembly for several terms and was also Mayor of Brisbane from 1885 to 1888. Charles Mayne also owned property in the Milton area, and some speculate the street might be named after him.

Other Maynes: Several other individuals with the surname Mayne appear in Brisbane's early history, including landholders, farmers, and community figures. While their contributions were significant, their direct connection to Mayneview Street is less documented.

Challenges in Identifying the Exact "Mayne":

Lack of official records: Unfortunately, there's no definitive official record stating the specific individual who inspired the street name. Historical documents often mention the street's existence but don't explicitly state its origin.

Multiple possibilities: With several prominent Maynes in Brisbane's early history, attributing the street name to a single individual becomes challenging. Without concrete evidence, it's difficult to definitively say who deserves the credit.

Despite the ambiguity, Mayneview Street undoubtedly holds a historical connection to the Mayne family's legacy in Brisbane. Their contributions to the city's development, particularly in the Milton area, likely played a role in the street's naming. While the exact "Mayne" may remain a mystery, the street serves as a tangible reminder of their influence on Brisbane's early history.

I asked Bard about the etymology of the word "main" and some examples of its use in compound words.

The word "main" has a rich and interesting etymology, boasting multiple origins depending on its meaning:

1. Direction/Open Sea:

This meaning of "main" traces back to Old English "mān," which simply meant "great" or "large." It likely referred to the vastness of the open sea compared to sheltered bays or harbors.

2. Emphasis/Most Important:

This sense of "main" originates from the Old French "maigne," meaning "strength" or "power." It later evolved into the Middle English "mayne," signifying "greatness" or "importance."

3. Sail/Mast:

This nautical meaning comes from the Middle English "mayne," referring specifically to the "mainsail" or "mainmast." It likely developed from the idea of the mainmast and mainsail being the largest and most important components of a sailing vessel.

Examples of "main" in compound words:

Direction/Open Sea: mainland, main channel, main course (nautical route)

Emphasis/Most Important: mainstay, mainframe, mainshaft, mainstream

Sail/Mast: mainsail, mainmast, mainboom, mainsheet

As you can see, the word "main" has versatile origins and applications, lending itself to various compound words across different domains. Its historical evolution and diverse meanings add a fascinating layer to its usage in contemporary language.

What's particularly interesting is that "main" derives from Middle English "mayne" signifying greatness or importance but originally from Old French "maigne," meaning "strength" or "power." One thinks of Charlemagne or Charles the Great as his name would be rendered in English. Speaking of Charlemagne and the Spanish Main, I happened to notice that there was a region between present day Spain and France that was called the "Spanish March":

The "Spanish March," also known as the Hispanic March, was a historical buffer zone established by Charlemagne, King of the Franks, in the late 8th century. It existed for several centuries and played a significant role in shaping the Iberian Peninsula's history.

Origins and Purpose:

In 778, Charlemagne conquered Septimania, a Visigothic region in southern France bordering the Muslim-ruled Umayyad Caliphate of al-Andalus (Iberian Peninsula).

To defend Frankish territory against Muslim incursions, Charlemagne established the Spanish March along the Pyrenees mountains.

This fortified frontier zone encompassed several counties ruled by Christian lords under Frankish authority.

Characteristics and Development:

The Spanish March consisted of various counties like Barcelona, Girona, Urgell, Pallars, and Ribagorza.

These counties served as military outposts and gradually expanded southward through conquests and assimilation of Muslim borderlands.

Over time, the counties gained increasing autonomy from Frankish rule, developing their own distinct cultures and identities.

Legacy and Impact:

The Spanish March played a crucial role in the Christian Reconquista, the centuries-long struggle to drive out Muslim power from the Iberian Peninsula.

The counties within the March became the nuclei of future Iberian kingdoms, including Catalonia, Aragon, and Navarre.

The cultural and linguistic influences of the Spanish March laid the foundation for the development of Catalan, Aragonese, and other Romance languages in the region.

Therefore, the Spanish March was more than just a border zone; it was a dynamic frontier that facilitated cultural exchange, political evolution, and ultimately, the Christian reconquest of Iberia.

History Channel article on the Reconquista: https://www.ncpedia.org/anchor/spain-and-america-reconquest

It's clear that Mayne would be the surname of choice for a family wishing to emphasise its status and importance in a region. In the United States, "Mayne" ranks around 16,000th based on census data and in the United Kingdom, it's estimated to be even more common, falling within the top 5,000 surnames.

While the prefix "re" is the only common one added to the root word "main" to give "remain" (continue as the main element), the following suffixes can be added:

  • -stay: Denotes a state of being the main element, e.g., mainstay (a pillar of support)
  • -line: Emphasizes centrality or direct relevance, e.* mainline* (the primary course or direction)
  • -stream: Refers to the dominant or popular trend, e.g., mainstream (the prevailing current of thought)
  • -force: Highlights power or influence, e.g., mainforce (the principal driving force)
  • -ship: Denotes a position or role related to the main element, e.g., mainship (the leading vessel in a fleet)
The name "Mayne" crops up is a wide variety of contexts, even on the labels of wine bottles.


One can't end this discussion without mention of the homonym "mane" which has the following etymology, to quote from Bard:

  • Origin: Proto-Germanic mano "neck hair of a horse"
  • Evolution: Old English manu, Middle English mane
  • Meaning: The long hair growing on the neck and head of some mammals, especially horses and lions.
Of course in Indonesian, "main" means "to play" and is pronounced like the English word "mine". Here is its etymology:

  • Origin: Austronesian language family.
  • Evolution: Proto-Austronesian ma-en "to do, make, act."
  • Development: Over time, the meaning in Malay and related languages like Indonesian specialized to focus on recreational activities, hence "to play."
The Indonesian translation of the word "main", in the sense of important, would be "utama".
