Last year I bought I used TI for my daughter who needed it for school. I got her the oldest version, the one which takes AAA batteries and communicates with the outside world through a serial link. A project like this brings to mind the possibility of stuffing a Raspberry Pi Zero in the battery compartment, hooking it up to the school WiFi, using a terminal app on the calculator to communicate with the Pi and in that way voiding the whole reason of using these ancient beasts in the first place. I won't do this of course - she's there to learn other things besides refining the art of cheating [1] - but it would be a tempting hack. An even more elaborate hack would be to replace the guts of the thing with a Zero running a TI emulator as well as some more useful stuff like ssh. The possibilities are endless... so endless in fact that I'm fairly certain this has been done already, somewhere.
[1] which in my days at school consisted of writing the translated works of Homer on a 10x10cm piece of paper, a good way to a) learn to write incredibly small and b) get those words to stick inside your head long enough so you don't actually need to consult the cheat "sheet" during the test.
One of my proudest cheats was cramming the keywords of an entire presentation in French on a tiny round piece of paper, stuck to the glass of my wrist watch, so I could literally cheat while the whole class and teacher were watching me. Somehow I actually got away with multiple glances, only receiving a single remark about "being a bit too focused on the duration of my presentation".
My cousin, who has always did have good entrepreneurial instincts, actually managed to turn a decent profit selling highly detailed printouts of micro cheatsheets at school.
It's because school is preparing students for life, where it would be outrageous to have written notes while presenting or speaking. What's next, someone else writing the words for you?
How exactly is it outrageous? You are there to deliver the message in a meaningful way, not to recite such message from memory. This is no theater or the cinema where you are playing a role and must be entirely authentic as a result.
Sure, literally reading entire thing from your notes in front of your audience is bad form as it fails to build the captivating presentation. It is just distracting for those listening.
But damn if this cannot ever work for the online presentation where the speaker isn't visible.
It's because school is preparing students for life, where they would never have any chance to look anything up, and could thus only use their own memory.
And that "you won't always have a calculator with you" thing math teachers loved so much? Yeah that didn't age well.
Yeeeah that's already being done for a a bunch of IT courses. Check out some of those "freelance work" sites, it's fairly obvious a bunch of those are someone's homework...
In the same way that my ability to use WolframAlpha to answer physics questions in no way qualifies me to say “black holes don’t sound like they could work, surely the way the in-falling particles get an increasingly well defined velocity as they reach the event horizon causes their position to become increasingly undefined until they are almost certainly nowhere near the black hole?”, which is the kind of thing I tend to say because I don’t have a physics degree, and given how physicists generally respond when I say stuff like this there’s a 5% chance I’ve said something interesting and a 95% chance I’m as wrong as 90s Hollywood script writers were about computers.
With sufficient preparation I could pass any physics test without actually understanding physics. A Chinese room within the mind, if you prefer a philosophy reference.
Thinking about it, I really should’ve gone with that analogy first — it keeps this in the category of languages.
I know you pulled it out of your ass, but your thought on the uncertainty principle and black holes is actually intriguing. A wave function that is fully localized in momentum space (as in has one definite momentum) has to be maximally spread in position space (as in its possible positions are diluted to the point of being everywhere so the odds of observing it anywhere are effectively zero).
IIRC some quantum properties like uncertainty have funny ways of being preserved in relativity. They pop out of the equations as unexpectedly nice coincidences, but they feel to good to be true. Like they clearly hint at some profound truth, but its on the tip of everyone's tongue yet no one can grab it.
I vaguely recall certain types of entanglement change in an interesting way under the Lorentz transform (don't hold me to that).
I searched WolframAalpha and I can tell you you are partially right. The universe macroscopically is flat so they remain in proximity to the black hole on the x,y dimensions but move arbitrarily far on the z dimension, which is how they bend spacetime and why they attract everything around them like if they have gravity. :-)
One of my university teachers allowed us a double sided letter sized piece of paper during the exam and we could put whatever we felt like on it.
This was brilliant because 1. In real life, you don’t memorize random facts. That’s what reference books and the internet is for. 2. Making the cheat sheet actually forced us to understand the material so they we could sum it up and for it on the page. By the time we were done writing the sheet, we had memorized most of it anyway.
Yet another demonstration how school is completely out of touch with the jobs they’re claiming to be preparing you for.
I had a couple teachers that allowed the cheat sheet, and it worked so well that I made them for every test, whether I could actually use them on the test or not. As you noted, it's such a great forcing function to identify and understand the most important bits.
I had an Econ teacher that did something similar but it was a note card. Thing was she reused the same bank of questions every semester and provided a study packet of sample questions that was a super set of the questions on the final. Some kids got wind of this and encoded the answers to the study packet on the index card. They were bizarrely accused of cheating.
I know someone who did something similar in analog electronics. The teacher asked them to come to their office, and asked them a few questions. As the student couldn't answer them, the perfect score was commuted into a failing grade.
Regardless of how you approach this, an exam is here to evaluate your level of proficiency on the topic at hand. If you sidestep this, that would be called cheating.
A university teacher allowed us to use everything during the exam, including a laptop with an internet connection. The only rule was that you weren't allowed to use any communication with other people, like messaging someone or asking questions on forums. Needless to say, everyone passed that exam.
For myself, the most-hated part of every exam session was having to memorize everything. That's what made me fail every single exam I've ever failed. I just can't bring myself to stuff information into my head and then give it back later. It's not a storage device. Yet most other teachers insisted that I need to do everything from memory. 95% of my school and university "education" was to memorize something, then recite it, and then forget it forever.
I've done open-everything exams (just no collaboration) and my experience was that it didn't change the mean grade, but it did increase the standard deviation. Students who were already mostly on top of the material could look things up and double-check their work, so their scores improved. Meanwhile, students who didn't really know what they needed to spent the whole time trying to find "the answer" in the book or online (and that's not the way programming tests work!), so in the end they either left the answer blank or put something totally nonsensical, copy-pasted off the internet. In a closed-book test, they would have at least tried to figure it out on their own, and maybe gotten a few partial-credit points.
Reminds me of when I was in high school. I found a terminal emulator for my HP48G, built a serial cable to connect it to my 2400 baud modem. I was able to use it to check my email in physics class. Of course I was only able to do that once; the modem was three or four times the size of the calculator with lots of blinkenlights on it, and trailing a phone cable half way across the classroom isn’t very subtle.
The ESP-01 is smaller, cheaper, less battery heavy, and already speaks serial so it wouldn't be hard to integrate it, just for the WiFi... And at a quick look there's a bunch of TI<->Arduino stuff out there in the wild it should be easy.
There are many ways to flay this hog, this is more of a thought experiment than a recipe for a TI-CH337. The ultimate hack would be to use a more modern version (with "high-res" screen) and replace/amend the guts with something which emulates the calculator - wabbitemu seems to work just fine [1] - but can also function in other ways. Add some key combination to switch functions and you have a mean lean cheatin' machine.
I cheatet so much with my TI. In every class we were allowed to use a calculator I would literally code everything relevant for the test into this small thingy. I still think I better memorized some of the things as my class mates.
Also I loved how it doesn't really communicate except with a cable no one had. So nobody expected me to share my 'cheats'
This gives me food for thought. I have young children, all under 10. The challenge is learning how to inspire them; you found a crutch that made learning less of a chore: converting the syllabus into chunks of code.
I can already see that the my two eldest will both need very different answers, but if I can figure out what theirs is, I can hopefully help them focus where my childhood mind would wander during study sessions.
I found it a lot of fun to interface with the TI calculators directly using the wonderful ArTICL Arduino library[0]. You can cobble together a link cable to imitate another calculator and hook it up to your microcontroller of choice.
I enjoyed making a QWERTY keyboard and news app over WiFi using the tiny ESP-01 (as, coincidentally, @shakna suggested in this thread).
There's enough hacks you can do on the 83/84 without hardware gutting tricks. Even in plain old TI Basic. You can easily automate most of a HS curriculum and make an unbeatable tic tac toe program, no internet needed. Its honestly the first coding experience I ever had.
And if IT use the Cisco management console, they get the location down to 3-7m diameter of every WiFi, Bluetooth, Microwave ++ that is using the same band as WiFi.
I was earlier in a startup that made an indoor navigation map, where you could get the blue dot without installing anything, by using this Cisco feature:
https://use.mazemap.com
Feels incredibly strange that anyone can publicly view all these office layouts, down to very specific room/corridor/stair layouts, occupancy status, of random private office and university buildings...
My school let you have two calculators so you could have notes on one of them and use the other. I don't really understand why, I'd rather just have paper notes. Fun things to play with though, the HP38G's we had had a nifty infrared communication thing so you could trade stuff with other people.
It can be relatively inexpensive, depending on which RIR you’re using. There are providers like [Neptune Networks](https://neptunenetworks.org/) or [Vultr](https://www.vultr.com/) that you can peer with from a VPS so you don’t need to get “proper” IP transit in a datacenter.
Oh, interesting -- I assumed you had to have a membership to the RIR directly (APNIC in my case, which would have been upwards of 1000AUD/month). Hmm... Thanks!
Oh, you're right. 1180AUD / year + 500AUD sign-up fee.. Still a bit expensive. If I had a business use case for it I'd be able to justify it, but it's too much for a hobby, unfortunately.
You "just" need to be in their reigon, and have justification. Usual justification is that you have two upstream networks and they'll announce your prefixes (generally with BGP). That's going to cost some more money, but there's specialist VPSes for this these days.
There’s no hobbyist program but neither is it corporate/for-profit only, from what I see.
There are few people(mostly network engineers or researchers by trade and/or business owners themselves) who are assigned ASN to their homelab gears from JPNIC. Knowing the right doors to knock etc.
i got my V6 and V4 space, along with my ASN though Hostus.us (https://my.hostus.us/cart.php?gid=55). I use Vultr and a few other providers. For V6 only, you can get the ASN and V6 space for around $50 per year, and the vultr server is around $5 per month... my own ASN is under https://as204994.net with links to some providers and details...
Check out the dn42 community if you simply want to play with the tech stack for free. The network uses the private AS range, allocates addresses from the private address ranges and peering happens over point-to-point VPN links.
I walked through doing this with my AS (AS398328) in the US (ARIN), both for fun and for security research. Happy to chat with anyone who wants to go through the process, it was probably $1-2k in total for ARIN fees to get the AS and v4/v6 space. Real transit is a lot worse though.
going direct to ARIN/RIPE/APNIC etc have some stricter rules (IIRC, in RIPE you need a company or possibly business, plus a bank account in that name). by going for somone like HostUs, they are sponsoring the account, so they need to verify you and ask questions, then setup the ASN, etc. Also, going direct will provide you with V4/V6 space allocations. They might charge a yearly fee (IIRC, its like 50 per allocation) but v6 is "practally" free but V4 will be a in a wait list... Finally, going direct, there is some sort of "kick back"... if the RIR makes more money than it cost to run the place, they reallocate fees back to the LIRs... so, you some times get money back... I have been tempted, but for RIPE, its 1400 per year, plus 2k setup... ouch...
I have my personal LIR with RIPE and they do allow signing up as an LIR without being a company. As an individual you need to provide proof of identity via government issued ID and pay 17% Dutch VAT.
When I signed up I got a /22 of V4 space and /29 of v6 space, although for new signups I believe there's now a wait list to get a /24 and that's it for V4.
Yeah, AFAIK the LIR model is specific to RIPE. The ARIN team does seem to put a decent amount of work into vetting and support/etc with pleasant interactions, so I don't think the fees are too unreasonable (but maybe not the best idea as an individual).
My experience in 8-bit is you can write 80% in C and then just focus and optimise the bits that need it in assembly. The rule is the same as ever, don't prematurely optimise (i.e. by writing everything in assembly), but the amount that needs optimisation is a bit bigger.
> Goes to show how much you can get out of hardware just by writing code sensibly in a native language (and native libs/tools, of course).
Personally, I find this a far less impressive demo of the SuperH SH-4 CPU than, say, Doom running on a graphical calculator. A http server (not https) simply opens sockets, writes a string, and closes the socket, a task which is usually purely I/O bound. Implement something basic like HTTPS (introduced in 1994) and watch this CPU grind to a halt.
I agree with the feeling, it's not really that impressive, but the HTTPS mention isn't accurate. Performance would be certainly lower, but remember the SH-4 was in the Dreamcast.
You can buy some niche boards[0] with SH-4, and I assure you, they can run Debian and they do SSL just fine.
C isn't in my mind close to the metal but potentially lets you be more sympathetic to the metal. Thanks for your drawing attention to this, I'm looking forward to reading.
TI is pretty clearly just coasting on being the one mandated by a lot of schools; there's no way you can justify them still costing like $100 and having the same capabilities as when I was in high school.
I'm a few years out of high school, but during my time anything other than physical calculators were explicitly banned due to the potential for kids to be accessing the internet during exams. I even had a friend who won one of TI's higher end calculators at a math competition, only for him to be banned to use it during exams because of its higher capabilities. Perhaps things have changed in the post-Covid world.
Yeah about the same here. I wrote some programs to handle quadratic formulas. Impressed the Algebra teacher who then let me take AP Computer Science so I can learn to program in Java...which I promptly forgot after graduating HS.
When I was in HS, at the exams we were expected to use our TI-84+ calculators, but we were not allowed to have any programs of our own, so they made us clear the programs before they handed out the problems.
Which you could work around by archiving and then unarchiving the programs. I remember having to do a soft factory reset for one class before exams, rather than just clearing programs. At least they took the policy to its logical extension
Just graduated secondary school in April. Just as a someone said in a reply below, anything other than a physical calculator is still banned during assessments. There are tools like Desmos, GeoGebra, etc... that may be used by the instructor and students during lessons though. Although it's strange, there is no explicit rule provided by our Mathematics faculty that bans higher functioning calculators I've only seen one person carrying one.
That's what I did 10 years ago when my TI-89 broke right before my Linear Algebra final. I somehow convinced my instructor that when I had my phone out, I was actually using the calculator on my phone.
TI still use really outdated hardware (some ARM9 thing) on their high-end nSpire models.
With the same price even HP Prime G2 has way better hardware (NXP iMX6ULL, Cortex-A7, 256MB DDR3, USB EHCI OTG) and wide software spectrum (no Secure Boot enforced.) I've put full scale Linux and Windows ARM (arm32 IoT) on that platform.
Not sure about Japan but in Poland the variables in problems are either symbolic and you solve it symbolically, or if they are given as values then they are usually chosen just right to not make arithmetic much of a bother (that actually results in a fun 'sanity check' that if you start getting something waaay crazier than 'normal' you double check if you didn't screw something up somewhere along the way or if there is a better way to solve it).
But everyone is taught to only substitute variables for values at the very, very end so calculators are not needed at all. At some point in education there is no point in testing arithmetic skills over and over again, the problems and the methods of finding out solutions to them are what matters
Exactly, same in the UK. So a typical first question in the maths exam we take at age 14/15 might be ‘Factorise the quadratic x²+5x+6’. No calculator needed.
We were allowed to use calculators when I took my school exams in the uk. But our exam questions often asked us to give the answers in surds i.e 3/4*√2 not as a decimal which our calculators couldn’t do then. Our teachers told us there would never be a question where the answer couldn’t be expressed cleanly using either fractions or surds, that we should practice doing the maths and show our workings on the exam paper and that if we were using a calculator we were wasting time doing data entry as the actual addition / division / subtraction would never be hard enough to justify it. We memorised a table of surds for 30º 45º and 60º angles but I’ve forgotten why now. Also they hard reset our calculators as we went into the exam.
Thank you so much for pointing out fx-115ES PLUS2! I looked for a good hour yesterday trying to find an alternative to the fx-115ES PLUS (first edition) with the same features, after Casio discontinued the original. I'm honestly embarrassed that I had overlooked this...
I do absolutely agree that Casio calculators are just wholly better than TI in general. Their menu driven interface is a game changer for me back in middle school. TI-36X Pro felt cumbersome and confusing, while fx-115ES was much more intuitive.
They're amazing little machines. I have a predecessor to that model, whose battery still works since purchased new for my school year starting in 2000. It's not solar-charged, either.
I’m not sure I understand. The calculator linked is the second version of that model, which to my understanding is identical software wise but looks completely different.
Sure there is. Go to Settings and move down to Entry. Hit Enter and you get your choice of Textbook, Algebraic, or RPN. Go down to RPN, press Enter and then Esc.
Thank you - I used the calculator more in the last hour after making this change than I had in the past month. I'm ashamed I didn't figure this out - I should have done a better job of RTM.
Checking in with a TI-30X Pro and get the equivalent (sqrt(6)-sqrt(2))/4 also in mathematical notation. All of my work is saved when I turn the calculator back on. Plus I can just set a flag for imaginary mode without a separate complex app so everything works the same in both modes. The screen is higher resolution and the multi-tap entry is pretty darn sweet.
Annoyingly TI-30X Pro is Europe only (also costs more, but looks better quality and design)... but you are right, it looks pretty good, as does the US-available TI-36X Pro. I will give one a try. My main gripe with TI is the school requirement for the TI-84 series.
For scientific calculators, I would agree. For graphing calculators they might be better on technical merit or cost, but everyone is going to write programs for the TI so you might as well get that one.
Agreed. For basic maths, the best scientific calculator is the fx83. The ES 115 is based on it. The graphics and controls and navigation is really good. Nothing comes close.
Must be a market specific model, because that one shows up for me in the .com tld but not in the regional one :-(
But from there I've started digging and they have so many different models with similar appearances... Anyone knows the difference between fx-82ES and fx-82SPXII?
They're exploiting an effective monopoly position (through schools mandating their usage). I can see that being enough of a reason to push back against that.
"Running MPI programs on a cluster of commodity hardware" was perhaps a sufficiently novel idea to warrant a unique name back in the 90s, but these days it's more or less the standard for all but the most exotic and expensive of scientific computing... and even those expensive custom supercomputers tend to still be x86 processors running MPI code.
Basically you don't hear about them any more because it's all Beowulf clusters now.
I think the "Beowulf" name (the name of the first well known computer cluster) was mostly a Slashdot meme. As Slashdot faded, so did the name "Beowulf".
Inferno is available for Nintendo DS, more info at https://gamebrew.org/wiki/Inferno_DS
I can verify that it runs, at least, on a Nintendo DSi, though I never actually did anything with it and didn't have another DSi (or enough knowledge) to find out if it could actually network.
Fair. But if a user has accessibility enabled, that should override the css itself no?
Also even with the focus outline disabled on other sites, I am able to navigate with the keyboard to text input fields. OP's site doesn't have any input fields so not sure why they have that CSS in place as I don't think it's doing anything.
of course just like with most places using content providers :) . It would take forever (relatively)to pull those off the casio vs the html text for the page.
Sure, but with fixed hardware resources you risk the site going down with traffic spikes like this, with AWS you have access to calculatorless options that can easily scale to handle increased request volume.
If you use an an alt-CaaS you'll won't benefit from Infinidash integration, but then again you won't have the Infinidash configuration learning curve to deal with so it could still end up a net positive.
I would argue it's not really hosted on the Casio then, since it's only static content the reverse proxy cache would hit 100% every time, except on TTL.
Now I want to see a website hosted by my favorite graphing calculator, the one that comes with the best UX for operating on numbers - RPN (Reverse Polish Notation). HP-48G
Why did I click on this expecting a calculator out of all the possible servers would withstand HN's hug of death? Smart of the commenters here archiving it before it inevitably went down
Because static pages on a calculator likely to be more reliable and faster than whatever hipster stack is popular running on some VC funded pile of compute power across all of Amazon's datacenters.
FWIW I still saw the link at #1, clicked it almost in exasperation after seeing it at the top of HN all day, and was pleasantly surprised to see it load. Bravo, little calculator.
The calculator's dimensions are: 21.3 x 87.5 x 180.5mm
A 1U rack comes in various depths, let's assume 1m (1000mm), and the width between rails is about 450mm. 1U is around 44mm in height.
So in 1U, you could stack them 2 high, 5 wide, and 5 deep (this leaves a little wiggle room for cables and such), or 50 per 1U, or 2100 in a 42U full rack.
I strongly suspect the webpage is entirely static and trying to run any sort of modern serverside framework would make it wail in protest - some simple dynamic elements using the native script might be doable though. It'd be neat to see if they could get a page counter up - just a dumb one that blindly increments the counter whenever any visit occurs.
we should all upgrade to gemini on casios, not sure if the processor is powerful enough to run the opentls encryption. perhaps a beowulf cluster can be made
Same as in the Dreamcast yes, albeit the Casio seems to be clocked far lower (29mhz in Casio vs 200mhz for DC). Also the memory seems a bit anemic at 60ish-kb vs 16mb main for the DC (+8mb videomem and 2mb audiomem).
It was a fine CPU for the era with parallel instructions but also a fairly deep pipe compared to other contemporaries so it did best with a bit of hand tuning. (We worked on a DC game and Transform&Lighting loops needed hand optimizations iirc)
Not quite the same CPU but they're all based on the SuperH ISA. The 32X and Saturn both had dual SH-2s, Dreamcast had an SH-4, and Casio uses SH-3 and SH-4. The Dreamcast SH-4 has an FPU but the Casio one doesn't.
That makes me think that a solar interntet is possible, perhaps routers and less intensive webpages may start moving if there was a value proposition for their owners. Sure it's not a whole solution just yet, but it's a start.
I'm not really proud of this but my 1st step into programming was writing programs to calculate things for me on the TI in high school.
At some point teachers made us delete programs in front of them before major tests.....someone else wrote a program that would simulate deleting programs and showed an empty screen which meant all programs were deleted.
I wasn't a dumb kid but I always felt like why just not program those things and have more free time? I guess I was always a dev.
This is really cool, but these days I prefer to host on virtualized Casios so I can scale up if I need Casio FX perf or down if I need Casio Databank perf.
Assuming Casios can run links or some custom browser - does anyone want to grab a snapshot of this page being rendered on their calculator to complete the circle?
Its a great mystery to me why American students have to buy expensive programmable calculators for course work. I vaguely remember reading that it is the result of lobbying by calculator manufacturers.
In my country even undergraduate science/engineering students dont need a programmable calculator. Some undergraduate programs like CS don't need any type of calculator.
You don’t, unless the teaching staff decide to include a lot of numerical work in exams. Which I don’t know why they would do. I would presume that a calculus course would teach you algebraic methods that you work out on paper.
In Swedish engineering schools, graphing calculators are banned from exams in almost all subject.
Why? I've done calculus and analysis in college and no one has ever used a calculator, I'm not even sure what you would need one for, can you give me an example (seriously curious)
The only time I remember needing a calculator in my entire education was some circuit theory because those Thevenins and Nortons get real ugly real fast (but even then you only need +,-,*,/)
The same way as pi, e and other constants, log(17) is just that. I never had to convert them to some decimal approximation in calculus classes
Edit: Ok, I remember now there was a statistics exam when we had something like Student's t-distribution tabulated on the exam sheet but I had to scrape my brain to find an example, it does happen though
Of course I had to at some point but in those instances I was at a computer anyway so I just used excel/python/matlab what have you, not a calculator like a Neanderthal
Interesting. I still have a Jornada 680, which uses the Hitachi SH3 CPU (compared to this Casio's SH4). It came with Windows CE, but there was a Linux distro for it called Jlime. https://en.wikipedia.org/wiki/Jlime
I think Casio calculators are quite popular in the UK - I used an fx570 through secondary school and university. It was the one recommended by my school, and then it was one of the three models (all Casio) allowed by my university[1]. I briefly had a TI83 for A-Level Further Maths, but I didn't use it much.
The fx-9750 would have been usable at secondary school (though it's more powerful than what you really need), but it wasn't on my university's allowed list.
Shame, because I only have an fx-970G Plus which can't run custom code besides BASIC. Otherwise I'd join you in this calculator-net! Awesome project, though
When I got my TI-89 long time ago, I remember that the TI programming scene was very vibrant back then. Many game ports and all of sorts of interesting software.
I can imagine if the site own who is stuck in Mars with a Casio fx-9750GII will attempt to use it to host a web page to communicate back to earth or something.
I have a soft spot in my heart for underpowered computers, but practically, I know this is kind of an unnatural fetish, and not really a healthy love. The little computer costs way more and consumes way more per watt than modern systems, and any minimal use case is better done via virtualization in a container on a more capable computer. Yet, the fetishism of all manner of obsolete, underpowered and wildly obsolete chip process technology remains!
By then, the screen will have almost 20% more pixels, the number of variables will be upgraded from 28 to 32, memory will be upgraded from 62kilobytes to 94kilobytes, and adjusted for inflation, it will still be the same price!
based on the hostname, although the httpd isn't answering, it makes me wonder if they also made the calculator speak BGP and take a full ipv4/ipv6 BGP table. Somehow with the RAM requirements I doubt it.
8 years ago I worked for an LED lights company which had a bright idea to put whole ucLinux + webserver to be ran on a microcontroller on an LED light to put a claim on just how smart they are, and that now they are "an Internet company" like as if the dotcom bubble hasn't happened.
So it was a $1 LED light board + $32 some old, and exotic MCU setup with own external memory, power supply, etc (even by 2013, ucLinux was already "very dead" without any new MCU support for 8-7 years.)
Aside from most extreme size limitations for the HTML UI, I was genuinely surprised just how snappy it was.
