#0036: Introduction of a website changelog

Preamble

I initially launched this website in 2020-02, with nothing but the default wordpress “coming soon” page to show for itself. Then after some months (2020-06) I finally managed to get round to actually publishing content onto it. And ever since then, I have been in a continual (albeit sporadic and intermittent) process of revision and iterative improvement.

So after about a year and a half of having this website online and functioning as intended: I now see the potential need for a master changelog here. A public facing log that will record all notable changes made to the website.

Utility of a public facing website changelog

Although this changelog will record all noteworthy changes made to the website as a whole. I specifically see the utility of this website changelog, with regards to noting changes made to the content of this blog’s articles themselves; rather than the website at large.

What I mean by this, is that it is more important to note post publication changes made to the content of articles. Than it is noting change in the wider website as a whole. This is because most changes made to the wider website outside of the articles hosted here will likely be concerned with aesthetics. Such as an addition/subtraction of a decorative graphic.

Simply put: they are less substantially important changes in terms of affecting the value proposition of the website itself. Although I do intend to note these types of things as well. At least for the most part. Although very minor website changes of this kind are unlikely to be noted.

That being said: I should restate the main function of this changelog. It is to note changes made to article content. This is because this blog’s articles (or blog posts) is where it’s primary (or most substantive) value is as a website. I.e. the primary reason a person may visit this site is to read the articles. This logging will allow readers to avoid confusion when/if they visit an article that they have already read, only to find that the content has to some degree changed within the interim.

My M.O. regarding editing published articles

Once an article has completed the development process and is finally published, I tend to have a habit of coming back to tweak and change things after the fact. This tends to happen some time time after the article is published when I have had sufficient time to rest and cool off on the topic. At this point I am usually more fresh minded, and hence I am more apt to find better methods to get my point across, as well as to spot any residual errors previously missed.

I am of the mind that I should also chronicle these changes as I make them. This is in order to avoid a sense of revisionist history. One caused by the absolute erasure of any mistakes such as: erroneous calculations, half-witted conclusions, or simple misinformation. I admit I am prone to getting it wrong a lot of the time. Especially when it comes to speculations made with limited observations, or ones unfortunately coloured with personal biases.

With that in mind, I should take a moment to state clearly the nature of this website in order to eliminate any misunderstandings or confusion as to the nature of this publication. As the name should suggest; this website is literally “a tinkerer’s blog”. The articles held therein are presented not as an authoritative source of information, but rather my (and only my) best understanding of any particular subject at the time. Complete with grammatical mistakes, spelling arrows, personal experience, and biases; as well as good ol’fashioned human ignorance and incompetence.

Although I (think I) do my due diligence in researching for articles; as well as re-reading my work several times over before publishing. This is in order to (give myself the opportunity to) catch any and all errors that I can. Unfortunately, often at that time: my mind can become exhausted with the subject matter, and would rather move onto to something else. Anything else! (Maybe even a refreshing punch to the testicles.) Add to that time pressures such as work and scheduled commitments. Well. They all add up; pushing me to hit the publish button perhaps earlier than I otherwise should.

Hence in an article’s final proofreading and finishing edits stage – I tend to find myself skimming sentences; or simply unconsciously mentally correcting the text grammatically and/or semantically. I.e. I knew what I meant by what I wrote, although I left the text in a state where it’s messaging is either ambiguous, nonsensical, and/or open to multiple unintended interpretations. Often I miss mistakes because of this and only really find them after I had some time to ‘cool off’ on the subject, as it were.

So that’s what normally happens with any given article. Post publish edits and refinements seem like a standard protocol for me. I even have a small to-do list regarding edits I need to make to past articles.

For example: my review of the video game “Princess Remedy: In a world of hurt”, has no critic of the game’s soundtrack. I somehow just completely forgot to mention it at all. I just blotted the concept of it out of my mind at the time of writing. So at this point: I intend to go back and insert this into it at a later date.

The thing is: I don’t like the idea of this additional content to suddenly one day appear within that article apropos of nothing, and masquerade like it has always been there from the beginning. I’ll leave that revisionist M.O. to the articles on political/activists news websites.

Hence, I need some way to communicate across to the audience that it is an add-on edit. In the past I solely used what I call an “update tag”. I’d insert a set of square brackets featuring the date before the add-on segment. Basically this: “[UPDATE: 2022-0X-XX] The music is …”. In the future I think I will use either the changelog alone to note smaller changes, and both the changelog as well as an in-article update tag for larger updates. Such as an entire additional segment to an article.

RSS

Just as an aside: if for whatever reason you want the raw undoctored initial publications. Free of my post publish meddling that is. Then please subscribe to my RSS feed. As it sends you the articles as they are published, and doesn’t update the content after that initial data transfer.

To do this, copy the below link into your RSS aggregator of choice:
https://www.tinkerersblog.net/rss

Closing thoughts

Although as stated the main reason for a changelog is for logging post publication article edits, it will also be good for keeping track of more general activity around the website. Things such as when new manual scans are added, or which pages have been recently edited. It’ll give the readership insight into where my attention regarding the website has been recently. Allowing them a sense of the frequency and general trajectory of my activities here. Which would be useful / hold value to anyone interested. (If there really is anyone interested … that is.)

I think it’ll add real utilitarian value to the website. But we’ll see exactly how much once it is actually implemented, and had some time to operate. Theoretically there is no reason as to why a website shouldn’t have a changelog. I mean it is a software product with ongoing development just like any other. However, I do wonder why so few other websites actually do have a public facing changelog.

It could be something as simple as a public changelog not truly being a necessity. Or it could be the fact that it would bring a level of perhaps unwanted transparency to their website. I mean it’s hard to simply vanish things, if you have a policy of documenting changes. I guess you could just not document the vanishing of the undesirable content, but still document the more mundane changes made. Although that does undermine the utility of the tool.

If I were pushed to give an answer: I’d say that most people just don’t want the work of it. For example: with for-profit websites tending to streamline their overheads (i.e. cut costs wherever they can), coupled with the continual communication and co-ordination between multiple levels of staff required for implementing and routinely updating a changelog: they most likely wouldn’t want to bother with one. Especially since there is little in the way of returns in terms of profit for the work necessary.

Even single owner general hobbyist websites probably wouldn’t bother with one either. As the single operator likely focuses their efforts on documenting their actual hobby activities. Rather than developing the website itself. I’d imagine that this is especially true in cases where the subject of their hobby or activity is unrelated to technology.

So unlike with this website, there’d be no on-topic value to discussing website development as a subject. Such as a website documenting: a homestead, hobby farm, painting miniatures, religious education, or bodybuilding to name a few. Basically any website where discussing the website itself is unrelated to the core subjects of the website… Website.

That’s all really. Changelog incoming. (Actually its already here, this article is a month late. :D)
Thank you for reading.

#0035: repair and analysis of a talon style folding lock knife

Preamble

I was recently given this folding lock knife to fix for someone. The internal mechanisms of which I found mildly interesting, so I figured it would be worth the time to document it. It may also prove useful for future reference incase I come across something similar.

Initial observations

The first thing that I noticed whilst examining this unit is the unusual blade shape. This is a talon type blade. It is a single edged, crescent shaped blade that curves forwards and terminates in a single point. It’s crescent shape, coupled with the blade edge being on the inner concave curve: give it both a visual as well as function resemblance to the talons of birds of prey. The blade is designed to roughly function in the same way: to pierce and then to hook. This shape of blade can easily convert slashing motions into pierces, due to the blade tip being the leading contact point.

The blade description above may lead you to think that the pictured example knife is a deadly weapon. And that would be the case, at least if not for my second immediate observation. Which is that this knife is a mass produced (I assume) chinese special tacticool toy knife.

It is rather cheaply made, and only really aesthetically resembles the weapon that it is aping. This pictured knife is just a box cutter. That is also it’s literal function currently. Its what the knife’s owner, who is a warehouse operative uses it for. It is also the only thing that it can be used for in my opinion.

Faults

The main thing that was wrong with this unit is that it was not maintained properly. The owner did not tighten the various torx screws on this thing as they worked themselves loose. This led to various joints and mechanisms developing too much play in them. This then resulted in the blade being seated at a crooked angle. Which in turn allowed the blade tip to scratch the handle as it was retracted into it.

Additionally due to the owner’s negligence: some of the various screws that loosened over time, fell out entirely and were consequently lost. This is rather unfortunate, because these fittings consisted of a paired torx screw and socket nut; that where sized to fit flush into the recesses of the handle plates. The socket nut especially is rather annoying to replace. Requiring a specific purchase as it is rather uncommon, and wouldn’t likely be present in any of my bins of miscellaneous salvaged hardware.

The blade itself also has an issue. The main one being that it is made from a miscellaneous soft junk metal; and the second one is that it was currently dull. So it required a basic sharpening, in order to make this knife operable. At least for the relatively short time period that the blade’s soft metal can maintain a serviceable edge.

Parts list

A complete version of this locking knife consists of several discrete components:

  • 1 x camouflage painted outer metal knife handle plate (left)
  • 1 x camouflage painted outer metal knife handle plate (right)
  • 1 x black painted metal inner frame with spring compartment insert gap
  • 1 x black painted metal inner frame with blade locking wedge
  • 1 x black painted metal finger guard with box cutter point
  • 1 x grey painted talon style blade
  • 1 x metal spring
  • 1 x metal spring compartment
  • 2 x plastic washers
  • 4 x smaller black painted metal hex screw and blind nut set
  • 1 x larger black painted metal hex screw and blind nut set
  • 1 x black painted metal trouser clip
  • 3 x black painted hex screws for the trouser clip

Tools and materials

Tools:

  • Round edge metal file
  • Knife sharpener rod
  • Torx screwdrivers (T7, T9)
  • Tweezers

Materials:

  • plumber’s grease (or equivalent)

Repair

There really isn’t much to say on the repair itself, as its pretty straight forward. I disassembled then reassembled the knife; fixing everything dodgy about it as I went.

Actions:

  • Completed knife disassembly.
  • Bent the blade locking wedge on the inner frame so that it stops the blade from folding closed more reliably.
  • Greased the blade’s damaged plastic washers to help prevent future wear.
  • Bent the blade spring’s hook into a right angle in order to get a better hold on the blade.
  • Re-greased the blade spring within the spring compartment due to presence of dry grease here.
  • Re-tightened all the screws and socket nuts that keep the housing together.
  • Added a stand-in replacement for a missing screw and socket nut pair that consists of two screws and a salvaged threaded brass insert nut.
  • Added a plastic screw and nut to help hold frame. I chose plastic so that I could cut down the screw and round off the nut easily so that it doesn’t snag the user’s hand.
  • Performed a basic sharpening on the blade using a metal file, then honed the edge using a knife sharpening rod.

The actual repair itself is hardly anything to be proud of. It wasn’t a hard repair and didn’t even take long. However this knife has been saved from going into the rubbish bin, for at least another couple of months, and that should be the main take home. This thing is ready for work again; and should stay that way for quite a while.

Recommended modifications

1) Grinding the blade edge and sharpening.

The knife blade could use a proper grinding and sharpening: if it to be used for anything more involved than opening boxes. I recommend grinding the blade down so that the angle of the blade edge slopes smoothly up to the mid-ridge. That way the blade can have more acutely angled edge.

This will consequently make the blade sharper than it currently is. A smaller angle will also remain sharper for longer whilst in use, due to the relative thinness of the new blade edge. Even as it dulls. Although the blade will also likely become more brittle and likely to snap as a consequence of the severe loss of material this newly angled edge will require.

2) Installing a blade backstop.

A blade backstop will stop the blade from over-rotating when it is extended. It will also prevent the blade from wobbling when extended by sandwiching it between the backstop and the blade locking wedge.

This knife likely already had a blade backstop of sorts, as it already has the screw holes where on could be mounted. However it was probably lost during use. As it is the blade overextends backwards when it comes in contact with any material that resists it.

3) Thread locker on the screws.

Thread locker such as “Locktite 243” when applied to screws prevents them from slowly working themselves loose during operation, due to factors such as vibration. This will extend the lifespan of this knife when applied to the screws that hold the frames together, as it will mean that they will (largely) no longer need to be checked and re-tightened at intervals.

And since we have already established that this knife’s owner is averse to maintaining his equipment: the lower the level of maintenance this knife needs, will be proportional to the extension of it’s operational lifespan. I.e. it will last as long as it lasts, if the thread locker can keep it together for longer, than it will last a little longer as a consequence.

4) Installation of additional retaining bolts.

I think that installing a few additional bolts and nuts to keep the frame together would greatly increase the overall structural strength of this folding knife. As it would share the strain of keeping the unit together amongst more points. This would allow this knife to be used in applications that require more force.

Although one has to be careful not to drill and install any bolts within the blades seating area within the knife handle housing, or within it’s pathway. Common sense right?

Post mod roles

As it is this knife tool is weak and too dull for any real work beyond cutting the tape off of cardboard boxes. however I theorise that if the above mods are made, then one would end up with a stronger, sharper, and more stable tool.

This would then allow the tool to used in a broader array of applications. For example light wood working, or bush craft applications. A talon style blade is good in both of those applications. The sharp hooked point is good for carving detail into wood. The concave blade is good for gripping and working with rounded objects like natural woods (sticks and branches). For example: for sharpening sticks, or for feathering wood to create tinder. It is also good for harvesting (in this case smaller) plants; as the concave blade helps bundle the stems together when cutting. Like a miniature sickle.

I could go on but I hope you get the point. The issue here is not with the knife’s design, it is with it’s flawed construction. If that could be remedied (or at least alleviated), then this knife could actually become a useful tool. It just requires work to get there.

Closing thoughts

Honestly, I actually rather dislike these types of low-cost low-quality mass produced items. This knife for example: it’s low-cost promotes replacement rather than repair: as it can very quickly make many repairs in it’s owner’s eye deemed as uneconomical. And that is assuming that the owner has a mend-and-make-do mentality to begin with. Most contemporary consumers do not. They have a use and replace mentality.

The main reason why a person may want to repair these things in my mind: is either philosophical (i.e. environmental conscientiousness, fiscal responsibility, anti-consumerist sentiments, etcetera); emotional sentimentality (e.g. hand-me-down from a relative); or if they are in severe financial strife and literally can’t afford to replace a £3.99 work knife.

Now look at it’s cheap build and materials. This factor exacerbates the issue above. Chiefly because it lowers the tools operational lifespan. This is the time it is in use, before it somehow breaks on it’s owner. Hence sooner putting them in a position to make the call on whether or not to either repair or replace the tool.

I do consider a knife like this to have been built with planned obsolescence in mind. Even though the term is hardly used for mechanical hand tools like knives; as it is usually reserved for electronic or computer products.

However, consider this: if the user does no maintenance on this knife. Then there are only so many operational hours that it is capable of before completely falling apart, or at the very least becoming inoperable. It’s shoddy build quality purposefully limits this simple hand tools lifespan. And when it is over, the user is expected to then purchase another one. That is a form of planned obsolescence.

I hate preaching, but please consider not buying this kind of shite. There are better alternatives available. Such as buying second hand quality tools. I always advise that people do the requisite research first. Then spend what they can afford in order to get the best value tools that they can, for their specific use case.

I said “Best value”, not most expensive. A chrome-vanadium spanner is a chrome-vanadium spanner at any price. Just because a person pays more for a brand name, doesn’t necessarily mean that their chrome-vanadium spanner is better than the off brand one.

Nowadays, it’s rather likely that they were both made in the same factory from the same material stock. An idea that would be laughable, if it wasn’t also true. Many brands on the market don’t manufacture anything. They purchase orders from the same OEMs then label the products as their own.

*proceeds to mount high horse.

If you absolutely have to purchase at the bottom of the market because you absolutely have no more money to spend. Then spend time instead. Time upgrading, fortifying, and maintaining your tool. This is so that it can last as long as you need it to. Or at the very least extend the time intervals between new purchases.

That being said, it is an unfortunate reality that most people who do mindlessly purchase bottom of the market products like this knife: are either unable; or more commonly, unwilling to invest time in their tools. They are in many cases content to use the shoddy tool in the short time until it breaks. Then purchase another bottom of the market shoddy tool to replace it with. Repeating this loop of short-sighted wasteful false-economy ad infinitum.

*proceeds to dismount high horse.

I feel that I should somewhat qualify my rather negative sentiments against these types of bottom market products. In the past I have worked within a small recycling facility, one that primarily serviced my local community on behalf of the local council, as well as the surrounding areas. (The point is that we weren’t shipping it’s garbage in.) I worked there as a materials sorter.

It gave me a certain perspective on the sheer volume of material wastage people engaged in. For a supposedly poor community, the amount of waste of useful materials was astounding. Every night I came across hundreds (not hyperbole) of very useable tools of all kinds. Everything from: screwdrivers, knives, drill bits, and spanners, to pots, pans, skillets, as well as whole bicycles some nights. All of that thrown away for recycling.

Many of these things were in decent conditions. Conditions that required either basic maintenance such as: sharpening, some hammering, replacing a handle, or realigning, or even a simple old fashioned cleaning. Gasp! Working there made me dislike a lot of these products; as when I now see them new: I think of where they’ll likely end up in less than a years time … In the fucking trash.

I just don’t like companies purposefully making tools/products that have such a short lifespan designed into them. I doubly don’t like it when these same products are purchased, used, and then wastefully discarded, by people whom I have heard a thousand times: claim poverty. But that’s another rant entirely.

Thank you for listening. It really helps.

#0025: Modifying a pair of Game Boy Advance SP earphones into an auxiliary audio dongle

#0025: Modifying a pair of Game Boy Advance SP earphones into an auxiliary audio dongle

Preamble

This article will consist of a basic tutorial on how to create a Nintendo Game Boy Advance SP (GBA-SP) audio dongle using a broken third party pair of GBA-SP earphones. Additionally I will also provide some related commentary (ramblings) on the similarities between Apple and Nintendo; particularly the way they design their products, and the way that their fanbases receive them. So if you have any old earphones you got as a child and broke yet kept, or maybe even recently purchased as spares and repair? Or if you are inclined to hear me bemoan tribal consumers and corporate avarice. Well here you are.

Creating an audio dongle

The actual conversion is rather simple. You just need to first cut the earphones off; then connect the wires as shown in the pinout and wiring diagram below.

Pinout

Audio jack
1: left speaker positive
2: right speaker positive
3: common ground

GBA-SP port
1: right speaker positive (red wire)
2: closed loop switch
3: (pin absent)
4: left speaker positive (blue wire)
5: common ground
6: closed loop switch

Now that we have the broad methodology of what to do to create an audio dongle, I’d like to talk about a few specifics.

Closed loop switch

In the pinout diagram I labelled pins 2 and 6 as “closed loop switch”. What I mean by this is that there is continuity between these two pins. This means that they are electrically connected to each other. I believe they are configured in this way in order to act as a switch when the plug is inserted into the device.

The electrical connection between the two pins effectively closes an open loop within the device. One that terminates with these pins’ respective sockets. This loop is probably used so that the device can know when an audio peripheral has been connected. This is so that it can act accordingly, by for example switching off it’s built in speaker.

Where to cut the donor earphones cord?

This might seem like a rather simple question at first. However in order to answer it, I needed to answer a few other questions before knowing where exactly I wanted to make the cut. The most important question that needed answering is does the pair of earphones actually work properly, or are they broken somewhere.

Assuming that they have at least one fault somewhere within them, where is the fault? If you can not easily identify it, yet the earphones are still not outputting sound. Then perhaps the fault is hidden. In this case, it will mostly likely be either at the earphones themselves due to snag damage; or if you are unfortunate, it’ll be located near the plug due to something akin to repeated flex damage. Please note that I am just speculating from my experience with repairing headphones.

Once the fault is found, then you must make a decision. Repair the fault, or cut if off (if applicable). In my case the fault was at the left earphone itself. I didn’t probe further than identifying roughly where it was, since I had no intention of repairing something that far down stream. I did however consider whether or not I wanted to retain the inline volume dial. After some consideration I decided to remove it. The reason for this is that I feared that the relatively low quality of the componentry involved; such as the potentiometer, or the PCB and it’s solder joints may actually negatively affect sound quality. So I just snipped it off. Didn’t like it much anyway. It didn’t feel nice to use.

What type of plug or socket to terminate the cord with?

This question was primarily answered by the materials I had available at the time. I did not have an appropriate female 3.5mm audio socket available. However I did have plenty of male 3.5mm jacks on hand; including ones that were corded. In the end I went with a jack that was colour matched (black) and that had the smallest profile.

This male jack enabled me to plug the GBA-SP into an auxiliary port on a sound system should I wish to do so. Additionally when coupled with a female-to-female 3.5mm audio adapter, it enabled me to use headphones or speakers with the dongle. This setup basically gave me the same functionality as having an adapter that terminated in a female 3.5mm socket, paired with a typical male-to-male auxiliary cord.

Soldering the jack

When it comes to soldering audio jacks like these: the first actual thing I did was prepare the heat-shrink tubing for it. Selecting the right sizes and cutting them to length. I prepared two pieces, which I thought was sufficient at the time; however in hindsight I should have prepared three distinct pieces. One to isolate each line.

As it is, it has one to insulate the central shaft from the surrounding ground pad, and one to act as an outer cover; protecting all three wires and acting as a general guard against flex damage for the entire cord. It’s good enough, but it would be better in my opinion if the inner two wires were separated by more than just the enamel coating of the wire strands themselves, as I have left them. A smaller gauge piece of heat-shrink tubing on the inner terminal to cover it’s solder joint would’ve been better.

As for the soldering itself: audio jack terminals like the one pictured can be rather tricky to wire up and solder properly. The reason for this is due to a range of factors. Factors such as: the general fiddliness and fragility of the enamel wires themselves. Although more-so the close proximity of the jack’s terminals to each other, coupled with the convex curve and orientation of their soldering pads, is what adds difficulty; as the awkward angles involved can diminish dexterity.

Additionally, the presence of structural plastic insulation between the terminals, meant that a lower heat and a shorter soldering dwell time was needed. This in order not to damage the jack’s plastics with radiant heat from the work area. Otherwise the plastic will melt and warp the plug’s general shape and structure. All these various factors can make it difficult to solder in a reliable and repeatable manner. However practice and work flow optimisations will mitigate these type of annoyances as one gains experience in this task.

An example in which I optimised the process: was by preparing the wires for soldering by removing their enamel insulation. This is because prior to this: during soldering, the enamel coating on the wires sometimes wouldn’t burn off within the liquid solder blob itself; especially with the necessary (relatively) low heat and short dwell time. When this happened, it resulted in the wire not forming a good electrical connection and/or not bonding physically with it’s solder pad.

I chose to prep the wires by burning off a segment of their enamel coating using a lighter. This had to be done in very quick manner in order to not oxidise the underlying copper strands too much. Burning off the insulation in this manner allows me to quickly solder the wires into place without worrying about any complications from the insulation.

After removing a segment of insulation in this manner, I chose to attach the wires in a way that limited any exposed segments of wire present outside of the solder joint. This is to limit any exposed conductors. Consequently, the solder joints were close to their respective wires’ insulated ends, and only used the exposed segments to get a good electrical connection within the solder joint itself. After-which I’d snip off any excess exposed wire that preceded the joint.

Testing the cable

The attentive readers amongst you probably have noticed that my repair notes contain several resistance tests of the various lines. Most I ran while working on the device, those are the numbers closer to the hand-drawn diagram. Some of which have been struck out. Discount those. The ones of interest are at the bottom of the notes. Those are the results from the post repair test.

The reason for the final test was because I was dubious of the quality of the cables that I was working with. As well as generally dubious of audio cables of this calibre. Specifically, cables that consist of a small collection of loose strands dipped in (I believe) enamel for insulation; then interwoven with additional plastic or nylon strands for strength. They all look and feel fragile and cheap. Having said that however, I should say that a post repair test is a good general practice. Even when confidence in the repair is high.

As you can see the left speaker line has a end-to-end resistance of 10 ohms. Five times that of the right speaker line, and ten times that of the common return (or ground) line. The right and return lines have acceptable resistances in general, and accurate relative resistances to each other. I expected the return common line to have half the resistance due to the doubling of the lines. However, what was unexpected was that the left line was clearly an outlier in line resistance. This in my opinion is due to either the low quality of the cable in general, or a hidden defect I did not find.

It’s not ideal, but upon testing with actual sound, the loss of volume on the left line speaker due to it’s higher line resistance was not noticeable at all. So I just left it be. The effort necessary to track the fault that is adding the 8 ohms to the line, is not worth the reward of having perfectly balanced lines for a GBA-SP’s audio. I used to call it laziness not ploughing down these types of rabbit holes. However as I have aged, I have come to understand the diminishing returns on investments that this type of perfectionism offers.

Related thoughts on Nintendo and their Game Boy Advance SP console

Now that we have created our own DIY audio dongle, let’s talk about why we needed to do this in the first place. In other words, why the Game Boy Advance SP doesn’t have a built-in 3.5mm audio port to begin with. In order to get at this answer, let’s first discuss a completely different technology company and it’s products. As to why, I’ll let you join the dots.

Many people today (2021) credit Apple as one of the most anti-consumer consumer technology companies, specifically with regards to their product design. Although there are numerous examples I could pick out, the one relevant instance here: is the removal of the generic 3.5mm audio jack from their 2016 iPhone 7 models. Anyone who pays any critical attention to this company probably came to a similar conclusion to my own. (Proceeds to pat self on back.) This naturally being that they did so in a bid to to sell first party audio peripherals at a premium. This being to their captive audience of fruity cultists. Cultists that would happily eat that up.

Why am I mentioning this in a Nintendo article? Well it’s because peoples’ memory is generally fickle and often mired with nostalgia; and the residual emotional attachments that it incurs. This leads them to holding double-standards when it comes specifically to childhood brands like Nintendo, often holding them to a lower standard of conduct than brands like Apple. These same people forget that their friend Nintendo did the same thing 13 years prior in 2003 with the incremental release of the Nintendo Game Boy Advance Special (GBA-SP) portable games console.

A games console that had no tangible advantages over it’s Game Boy Advance (GBA) predecessor other than a few quality of life (QoL) improvements. Both consoles played exactly the same games, however the SP boasted: an internal rechargeable lithium-ion battery, and an LCD backlight. For consumers tired of repeatedly buying new AA batteries for their GBA, or always awkwardly angling the unlit LCD towards a light-source whilst avoiding glare; these were improvements worth investment. Those of you who can read between the lines, might’ve guessed that this internal battery naturally required a specific Nintendo battery charger. A theme that they continued in later products such as with the Nintendo Dual Screen portable console (NDS).

However, a more apt feature of criticism in the iteration from the GBA to the GBA-SP, is the removal of the 3.5mm audio jack. Why did they do this you may ask? Well, now I could be wrong, but the cynic in me says that it was to facilitate Nintendo selling official audio peripherals at a premium, to their captive audience of pedantic neck-beards in waiting. That’s us mate.

Laughably, Nintendo’s official response against their audience’s pushback in 2003 was basically the same as Apple’s in 2016. They both said something to the tune of: that the new device simply didn’t have the space for a 3.5mm audio jack. Apple added some device waterproofing claims to this as well. But the core reason was the same: that there’s simply no space for it. Now shut up and buy our official peripherals. Peripherals that use the same port for both audio output and power delivery. So good luck using wired headphones and charging the device at the same time. Enjoy.

To cut it short. My point is that Nintendo has proven themselves to be as anti-consumer as Apple when the mood takes them. However it saddens me that their customers are prone to look at this company through rose tinted spectacles. Often even shouting down valid criticism, yet many within the community still consider themselves distinctly different from the stock of Apple enthusiasts.

That’s what happens when one thinks with their feelings. It’s tribal fanboy-ism at it’s finest. People for whatever reason forget that an individual’s relationship with a company or business like Apple or Nintendo, is strictly transactional. Nothing more. They are not your friends. A corporation does not have the capacity for camaraderie, or loyalty. Only the capacity to take advantage of such feelings in order to sell more to the same people.

Obviously, I am not talking about the entire consumer base here, just the vocal fanatics that seem to dominate public discourse. If anything a logical or reasonable person who likes the products of a particular brand to the point of becoming brand loyal; should ideally, be even more critical (than the average Joe) of their chosen company when it strays into anti-consumer practices. Due to their investment within the brand and it’s products. They likely would wish for them to stay good, more than a person who isn’t all that invested. But that’s not the world we live in. Instead the more invested a person is in a brand, it seems the more likely they are to tribally defend them regardless of circumstance. It’s sad really.

Closing thoughts

I know what you might be thinking, this article is nice and all, but it’s also almost twenty years too late. I mean in previous years getting a hold of an audio dongle for the GBA-SP might have been troublesome or expensive. Back when (the famously litigious) Nintendo were still protective of the console. However in 2021, one could easily purchase a NEW Game Boy Advance SP audio dongle from Ebay for less than a fiver. Since Nintendo doesn’t care much about protecting the rights to peripherals for a console that old (read unprofitable). Sure, the item that you buy won’t be an official Nintendo product, or even a notable third party contemporary brand peripheral, like Competition Pro. But it’ll work. Probably.

example of an unbranded Ebay adapter

To answer that question: Yes, yes you could. You could purchase an unbranded china special peripheral for your almost twenty year old console. Alternatively you could also make use of any old and/or broken first and third party peripherals that you may already have lying around, or even purchased in a mixed joblot or bundle. Essentially converting (basically) e-waste like that into a useful cable. One made to your exact use case and specification no less. Chances are your convert will also be better quality than a bought cable depending on what materials you use to make it.

Mine isn’t, I made mine from a pair of Competition Pro earphones. But still you get my point; I bet if you made yours from a pair of official Nintendo earphones (should you happen to have them), they might be better quality. As for making something for a specific use case: I totally use mine to blast Castlevania: Aria of Sorrow’s soundtrack, via my home sound system. I do it for maximum “immersion” during my midnight gaming sessions. I also want my neighbours to know that I am cool. The banging on the wall seems to indicate that they do.

Thank you for reading.

#0016: Software recommendation: Firefox Monitor and haveibeenpwned?

https://monitor.firefox.com/

https://haveibeenpwned.com/

Preamble

In a bid to make more immediately useful content, I’d like to start recommending some of the various tools that I use. In this case it is an online service. Namely Mozilla’s Firefox Monitor; or more to the point, it is actually the website: haveibeenpwned.com (HIBP), which Firefox Monitor uses to enable it’s service.

What do they do?

In essence Firefox Monitor and HIBP are used to check whether or not an email address is associated with a recorded data-breach. Keyword: “recorded”. It does this by using a database of known breaches provided by haveibeenpwned.com.

The purpose of this service is to allow people to ascertain whether or not, an online account (and the user information there in) associated with the email address: has been compromised in a known data breach; and thus in need of immediate remedy. Things like: changing passwords, recovery phrases, and generally being aware that any potentially sensitive information associated with that account, such as: full name, mother’s maiden name, GPS location, education, birth date, telephone, city, school, or business information has now circulated within the hacker community.

Additionally, it helps to know which company is to blame for the spike in volume of spam and phishing emails, that will most certainly accompany said breach. I don’t know about yourself, but that’s something I’d certainly like to know.

Why is this service important?

It is my belief that every solution begins with awareness, the awareness of the problem. Only then can we move to better the situation. This tool gives you exactly that.

In my opinion, the main reason why I think this tool is important is because the companies involved in the data breaches themselves are loath to make their customers aware of them. Even though it is in their user’s best interests; it is not in the businesses best interests to advertise any breaches beyond the legally mandated/enforced minimum. Furthermore, who knows what that actually even is when dealing with global or multinational companies that operate over many legal jurisdictions. This is especially true when dealing with larger companies with entire legal teams at their disposal.

This service is important because (still just my opinion): companies in general tend to quietly patch any security vulnerabilities as they find them, and move on hoping no-one has noticed. This is especially true when there is no internally confirmed security breach.

Whenever a confirmed breach does happen, the first thing that the company responsible does is downplay the scope and severity of it. This may (and probably does) include: not even publicly reporting the breach until it is already made public elsewhere, often at a much later time. In many cases there is even resistance to acknowledge fault after the breach is made public. This is most likely a bid to exonerate themselves of any potential legal liabilities involved.

At the very least acknowledgement of fault could be seen as weakness. Weakness that will shake public confidence in the company and/or service. Therefore it is in their best interest to maintain the general illusion of control and/or competence. It’s corporate PR 101. It’s just a shame that the company and it’s users’ interests don’t align within this circumstance.

Why should people use these tools?

Both Mozilla Firefox Monitor and HIBP are free to use publicly available tools. Both tools come from reasonably trusted sources. Firefox Monitor is the product of an open-source community driven effort, giving it a certain level of transparency. And HIBP was developed by Troy Hunt, an authority on the topic of digital security. Even if you don’t know who Mr Hunt is (and I didn’t prior to this post), the fact that the Mozilla team decided to use his HIBP database for Firefox Monitor means that they are vouching for it.

More importantly, the tools themselves can assist an individual with regards to protecting their personal information online. They do this by allowing the individual that exact thing that I mentioned earlier: awareness. Awareness of whether or not that person’s email associated account information has been circulated, and which company is at fault for it.

For example: if you used the tool and because of it now know that, an account associated with your email with company X has been breached; and along with that breach your “security questions” were revealed. Then now you know to both remove, and not to use those particular security questions, with any future account … ever. As they are basically permanently compromised. Forewarned is forearmed.

Difference between Firefox Monitor and haveibeenpwned?

Firefox monitor is a very slimlined version of the HIBP tool that gives the lay user just what they need, without overwhelming or putting off said lay user. It is rather idiot proof; merely requiring user’s to input their emails and press enter. That’s it. Firefox monitor also has been bundled in with a few basic articles on good security protocol, that may be helpful to the average user. Common sense stuff a lot of it, but you know what they say about common sense.

Although Firefox is the simpler tool to use, it must be said that HIBP is a far more robust tool. And the one that I recommend. This is because in addition to searching email addresses, it allows searching via: passwords, and domain names. The website also allows users to browse a catalogue of breached websites without running a search. Extracts below.

Ever wondered how many accounts have been breached because they used the password “love”? Wonder no more. According to HIBP, its 356006 times.

I have also perused a nice little selection of companies from HIBP’s catalogue of known breaches that you may find interesting.

Personal experience with a data breach.

Just an aside if anyone is interested. From reading the above “Why is this service important?” section, you might have gotten the idea that I may be ever so slightly cynical about the companies involved in security breaches like these.

Frankly speaking, whenever data breaches do happen, I do not consider the corporations involved to be “victims” of cybercrime, as many others seem to do. It is a nauseating sentiment. One that condones bad behaviour. This is because it is my personal belief that the vase majority of the cases are due to one core thing: a dereliction of duty. Them failing in their duty to protect the data that they collected. Little more.

In addition to consuming the various news articles about data breaches over the years. Ones that had the general themes of corporate incompetence. Like for example: employees carrying around sensitive data on unencrypted thumb-drives, only to lose them on the train. I also have a few examples of companies that leaked my very own personal information. All of this has coloured my opinions thus.

The most memorable is the online virtual tabletop gaming website roll20.net. The thing that rubbed me the wrong way about them is that at no point during the process did they ever take any accountability for allowing it to happen. They did eventually outline what information was taken, but they never offered an apology for their lax in security. Instead they covered it up with boiler plate (legal friendly) corporate speak.

Example: “The investigation identified several possible vectors of attack that have since been remedied. Best practices at Roll20 for communications and credential cycling have been updated, with several code library updates completed and more in development.” Assuming that is indeed true, the same could literally be said by any company involved in a similar data breach – just change the names.

Although from what I understand by reading the article that they linked in their post, technically (purely technically) this appears as though it’s not their fault. But rather it was due to the underlying technology that they used. At least that is the implication presented. I’d argue that they still made the decision to use said tech, and thus vouched for it by doing so. Making them responsible, at least tangentially. At least enough for a simple sorry. The closest their customers got to an apology was a “Frankly, this sucks.” Writing it in an official company blog post that they passed for a conclusive public report; authored by Jeffrey Lamb, the Data Protection Officer.

I remember thinking at the time that whoever was writing this was good at the bland formalities of corporate speak, but otherwise is (and excuse my French): a fucking dickhead. You have to keep in mind reader, that they only knew of their own data breach because of a third party report. One that was published months after the fact. The report was published in February of 2019, and the breach happened (according to Mr Lamb) sometime late 2018. No apology warranted, not even for missing the hack, until a third party told you about it months after the fact. They then go on write their conclusive report in august of 2019. So nearly a year, between data breach and the final public debrief, where they outline exactly what data was exposed. I call that incompetence. “Data Protection Officer” more like resident salary sucker.

The ultimate lack of accountability is what really rubbed me up the wrong way here. And why would they be accountable, there is little in the way of consequence it seems for these messes. There are even examples of customers defending roll20 in the comments, referring to them as “victims” of cybercrime. They aren’t the victims here idiot, you are! I’ll include some choice examples of this for your entertainment. Its customers like that, that make businesses feels like they don’t have to be accountable either for their actions, or in this case general inaction with regards to proactively protecting customer data. Please read through the example comment thread.

You really can’t reason with people like that. They have too much emotional stock in a corporation to admit to themselves that they got screwed by it. There were even people actually praising roll20 for it’s meagre efforts. A sum total of 2 blog posts, some notice tweets/emails, and for patching a hole in their own boat. Thanks roll20, stellar job. Shame about all my cargo sinking to the seafloor for the bottom feeders to enjoy. I mean you only lost my full name, my IP address (so my physical location), my password, oh and some of my credit card data. Don’t worry about that roll20 (not like you would), that’s my problem. Fuck those types of customers. Wankers.

Moving on. Another example of a gormless entity losing my data is ffshrine.org. A final fantasy fan site that I registered with in 2010 I believe; and haven’t used that account since 2010. Ideally, they would have flagged the account as non-active and deleted it after a couple of years. But alas, instead they just kept whatever details I gave them for the five years until their 2015 data breach. Where they lost subscriber passwords and email addresses. No warning email post event, nothing. Radio silent. I had a similar experience with tumblr back in the day. Radio silent. No accountability. Are you sensing a theme here, dear reader?

Closing thoughts.

I have written far more here then I initially wanted to, so I will keep this summary short. Tools like haveibeenpwned and Firefox Monitor are things that you as an individual can use to help protect yourself in cyberspace. They can help you take proactive measures to safeguard your own data. They can also show you evidence that the large corporations really aren’t as professional or as infallible as they like to appear.

And that when, they make mistakes; mistakes such as losing your data. It is often you that has to bare the brunt of the repercussions, with little if any repercussions to them. Maybe they incur a temporary stock dip. But the fact of the matter is, they’ll recover from it. However whatever data you provided them for safe keeping, well that’s now permanently out there. Enjoy.

For example. To this day I still get phishing emails that say something like: “hey MY_FULL_NAME, YOUR_BANK has detected multiple login attempts using PASSWORD_FROM_FFSHRINE.ORG to login. We have frozen your account because we suspect fraudulent activity. Follow the obviously dodgy link provided and give us your security questions to fix this.” Although I can recognise a phishing scam when I see one, many technology illiterate users can not.

And make no mistake, the companies that were lax in their security. The one’s that have the attitude that breaches happen; are the exact ones to blame for the perpetuation of the black market information economy. An economy that preys on people; the real victims. The people who trusted these corporations with their data, thinking it in safe hands. Not the corporations themselves whose lack of diligence and general incompetence allowed for the data that they were trusted with to be exposed.

Jeez… that got a bit preachy towards the end. Didn’t it? Sorry about that. It’s just seeing companies fobbing off their responsibilities, and then seeing customers with Stockholm syndrome defending these same companies against criticism – really ruffles my feathers.

Anyway, thanks for reading.
