Tedious Takeover, Regulatory Style

Filed under: Dark Modern Ages, Outreach — Diana Coman @ 11:23 a.m.

Motto: for your own safety and security

In 2017, the UK has enacted a shiny new Act1 that became effective this very year (2019), in April. The core of it is to make it abundantly clear that higher education in the UK has not much left in common with the ancient tradition of focusing on learning and advancing knowledge. Instead, the new Act states clearly that the very term "higher education"2 will by law apply only to those who submit humbly and fully to the newly created Office for Students (OfS) whose stated "four primary regulatory objectives" read:

All students, from all backgrounds, and with the ability and desire to undertake higher education:
1. Are supported to access, succeed in, and progress from, higher education.
2. Receive a high quality academic experience, and their interests are protected while they study or in the event of provider, campus or course closure.
3. Are able to progress into employment or further study, and their qualifications hold their value over time.
4. Receive value for money.

Do you see anywhere in there anything at all about knowledge? Anything at all about personal improvement even? Sure, if you *already* define your "learning" along the lines of "academic experience", your "knowledge" along the lines of "qualifications" and your personal improvement along the lines of "progress into employment or further study", I guess you are plenty served there, fully protected and well looked after. After all, the less "you" there is left, the less trouble you can ever get into. Just progress between these walls here and those walls there - we're building more walls too, don't worry, you'll never have to go outside of any walls really - just stay between the walls and enjoy the... experience, I guess? Oh, it's called academic experience, just so you know, it's all the rage to have one or two or even three of those now, so go for it! And never mind the money either, since you'll receive value for it, the OfS has it written right there, at point 4, ok? Not to mention that having a huge debt will be all the rage by the time you finish the ... experience.

To move further from the above - if you can, because honestly, by this point and under those definitions I already lost all interest in having anything to do with this particular brand of "higher education" - let's see exactly what does this OfS really do and when would you actually have to suffer them around. Perhaps it's just for those institutions that are indeed not independent anyway but fully public-funded and thus perhaps quite rightly saddled with all the attendant indignities? But of course not, no, why stop there! And how *can* there even be - says the bureaucrat arching his eyebrows in extreme surprise - recognised education outside of the state-mandated experience? No, such thing is not to be tollerated3 and therefore, any institution that wants to be able to award its own degrees has to register, bow and bend over for the OfS to consider it at will. Even for that procedure there is some prescribed progression, of course, and while the wad of paper doesn't go quite as far as saying that nothing else than *that* particular form of worship will do, it can't fully keep itself in check either and so makes a note that if the route taken is not the "typically" taken route, then you should talk to them first, before even applying (let's all chant now, the logical why: for your own safety and security!). Just in case you were curious, the "typical" route for an institution applying for its own degree awarding powers is to have been first for at least 4 consecutive years in a validating/franchising agreement with a degree awarding institution.

Trying still to look at more palatable options, I looked first at what exactly is included in "degree" and here it is: anything foundation and bachelor's (aka undergraduate) as well as master's and doctorate. So what's left? Well, you could in principle go for something like "further education" that is supposedly filling the gap between finishing school and going into either higher education or work. But of course, that doesn't have much to do with anything at the end of the day and moreover, if you actually do take in those under 18, you end up in the other (even wider, since more established already) wad of regulatory paper - experience-ensuring for children since they are not classed as adults.

While I read further and further through a lot of tediousness, I really can't summon any reason to further spend time on dissecting it here since there's no benefit I can see from it. Given the above, I'd rather make my own "institution" altogether since dissociating from those4 is a benefit all in itself but if you really see some path that might still be worth to follow in there, please leave a comment.

And if you are here in search of what once used to be called higher education (and is called so no more), have a look at younghands.club and The Pageboy's Pledge and come talk to me.

  1. It's called HERA to stand supposedly for Higher Education and Research Act 

  2. Also related, "reserved" words: university, university college, accredit and derived words, polytechnic, university centre. 

  3. and for very valid reasons, I suspect, since imagine the trouble then - you might get some pesky real thing that you can't control and then what are you going to do?? 

  4. Come to think of it, I'm not even sure that "university" is worth claiming back given its roots; if anything, I suppose I'd go for "academy" but even that is used around here, in the usual maddeningly confusing way, for some sort of school-trusts; overall my already-chosen younghands.club domain stands probably best as it is, after all

The Pageboy's Pledge

Filed under: Dark Modern Ages, Outreach — Diana Coman @ 7:11 a.m.

  1. I ask for help to expose and correct my mistakes so that I can learn from them and grow to be a better person.
  2. I commit to my own improvement through training as directed by my Master.
  3. I practice at all times unflinching honesty towards myself, my peers, my betters and my Master.
  4. I open myself up to take in fully and make the most of my Master's feedback whenever gifted and in any form given.
  5. I submit to my Master's judgement at all times.

So help me my own intelligence and cursed be my own stupidity that is holding me back!

Silently Unhappened on TheOdinProject.com

Filed under: Dark Modern Ages, Outreach — Diana Coman @ 2:49 p.m.

From the series of "I must be doing something right if *they* are so afraid of me", I had today the lulz surprise of finding out that a derpy forum1 "unhappened" silently my account2. As in literally, vanished entirely not only my "page" but also what comments I left for others leading to the great achievement that now there are replies to my non-existing comments3. Wouldn't you say that's great for learning? You get for once a user who can and is willing to actually help others around and then you ...unhappen this user without a word even because... what exactly? No idea but possibly they have a bucketfull of "oh noez" that I kicked over without even trying or something4.

Oh noez and all that but imagine it - after making an account and engaging with some newcomers there for their benefit5, the loss on my side is... what exactly? That I will now totally set the bozo bit on this particular derpy forum? That they give me now an excellent antecedent as to why exactly it's a mistake to even take any notice of their "forum" interface and accounts and all that pretense at all? And that clearly from now on I'll document upfront each and every descent I still deign to make into such sad holes? Or perhaps that they are slowly but surely adding concrete fuel to my otherwise sluggish motivation for pillage and burning, that must totally be their gain I'm sure.

  1. Since can't derp without pretense, it's called theodinproject and I'm not going to link it, no. It has a stylised hunting trophy icon and is otherwise a sad trap for web-developer wannabe misguided souls. It runs on "Discourse" too so that it's in *that* bucket rather than in a different bucket (e.g. flarum, *BB and so on.) for all the difference that makes to the caught crabs within. 

  2. Here's what it says today at the link for my account, preserved in amber for the future: archive.is/FcGC6 

  3. Here's an example of a reply to one of my comments and I'll let you judge how terrible my comment must have been given the reply: "That's an excellent point - I did take some statistics/logic and reasoning courses as well, though, so hopefully that'll help with the literal-ness!" 

  4. By now it's probably extremely easy too as I'm clearly alien to them. 

  5. In fairness it was all of 20 minutes first-pass sort of thing, to get the pulse of the place - apparently it didn't even survive the lightest touch, who knew there are such wallflowers on the internets.

The Young Hands Club

Filed under: Outreach — Diana Coman @ 9:08 p.m.

Since I already have a eager young hand and it turns out that even online young hands still need some space in which to mess around as much as their growth requires, I've went ahead and set up The Young Hands Club precisely for this purpose. A sort of very public learning club if you want - and even if you don't!

Now let's see what comes out of it in one year's time. The opportunity is there, the options are all yours supposedly so... what will you *do* about it?

My First Hours on Dev.to

Filed under: Dark Modern Ages, Outreach — Diana Coman @ 2:46 p.m.

As I really have too little time to waste any of it on fretting about how to start on things, I just picked Dev.to as the first online place to explore in search of young hands that grow from their right place and not from arse1. The choice was quite arbitrary really - it popped out on my unordered list as a relatively lively place and it uses GitHub old accounts so at least I did not have to make yet another "account". As a result, I now have in there too, that same old end-of-uni photo of mine that GitHub also has but so what. Anyway, to start it off, I gave them some content for free, sure, what's a few paragraphs to me now, here it is:

Come work on what matters, so you matter too.

I'm part of TMSR - the place where well-thought Bitcoin innovation happens steadily, publicly, unfashionably and with inescapable, far-reaching consequences. From a new model of software development to a MMORPG and building up a working market for computer artists plus everything software and hardware in between, the focus is at all points on owning what you do and growing your knowledge and ability at a sustainable pace.

The programming language of choice is Ada (with a fully-documented rationale as to why Ada) but work with legacy code includes C, C++, Python, Lisp and potentially anything else really.

Come work with me on things that matter, if you want to matter too. I write (and have been writing for a while) at http://ossasepia.com

The post above quickly got a few "hearts" and so far (1 day later) precisely no comments at all. Apparently love is easier to get than conversation, did you ever notice that? And what does it actually tell you, hmm?

The easy love aside, I didn't really wait (or expect) for any conversation to actually start from my first post, no matter what I'd have written there2 and so I just started looking around at the whole thing instead, trying to figure out its structure and therefore some way to *systematically* explore it. That quickly bumped into the obvious fact that the whole thing seems rather on purpose built *against* systematic anything. There are tags for instance to group supposedly by interests the content and you can "follow" tags even with "weights" attached but you can't see ALL tags (I know because I asked them, right there, in the "hello" thread, yes). You can see "the top 100" tags and supposedly that should be enough for everyone, screw the unpopulars, apparently I'm not supposed to be able to find them even if I am willing to go through as many tags as it takes to precisely reach them too! There are also profiles of course and you can "follow" those too but again, no way to actually see a list of them and be able to just go and talk to each one, no. Gotta try and map the space through the conversations that they feed you (literally, it's a "feed", right?) or otherwise go pretty much by chance, here and there, looking under each stone in search for people nowadays. Oh, and the platform is some Open Source pile of code, of course. Anyways, doesn't it strike anyone as really weird this thing where precisely online stuff that is by its nature exactly fit for systematic organisation and access is instead by design anti-systematic? Note that it's not just a matter of "offering also a fuzzy path to follow" but rather limiting the option to that and nothing else.

Anyways, 100 tags at least are better than none, so I started reading from there, for lack of any other better strategy really. Reading3 and commenting of course, since the whole point is to engage with people, what else. So after a few hours yesterday reading and commenting around there, here's how my dashboard on dev.to looked like:

Looking at the numbers this morning (after another 15 minutes spent on dev.to), I have: 1 post published (with "under 100 views"), 29 comments written, 10 "followers" and 4 "total post reactions." Hopefully I find a way to get faster at this as I do it more since I can't say I really have as much time as the current rate promises to eat up.

As for people actually following on what they said and making their way to irc and/or to this blog (or Stan's, since there was one DrBearhand whom I pointed towards FFA), I'll believe it when I see it happening and not earlier. But in any case if those I reached already fail to actually act on their own words now, it's their failure and nobody else's anymore, certainly not mine - from here on, it's on them entirely. What do you think the actual rate will end up like, 1 in 100? 1 in 1000? 1 in 1mn?

  1. It's Stan's term-of-art, see the logs

  2. I suspect I'm getting old really, there's no other explanation for this sort of lack of silly expectations here. 

  3. Really, having read lots and lots of legacy code prepared me for everything and anything, there is that.

Growing Young Hands

Filed under: Outreach — Diana Coman @ 5:11 p.m.

A recent conversation in the forum highlighted the need for me to re-adjust some of my priorities and push more to the forefront and into the light of purposeful activity the building of helpers too, not only of code. While this part is certainly not new to me nor otherwise entirely neglected up to now, it's clearly also not where I'd want it to be.

Over the past few years, in addition to the technical work that is indeed over-represented on my blog1, I have also spent some hours every week with young people (other and older than my son) mainly on Maths, occasionally on bits and pieces of programming. As such, I effectively planted some sanity seeds in fertile soil but this hasn't yet yielded any new direct contributors to Eulora or even to the wider TMSR. In part this is perhaps because they are yet too young2 but it might also be the natural outcome of my very leisurely (as opposed to tightly focused) approach to this side of things, doing it occasionally and selecting only out of the relatively small pool of those who are physically close enough to come to me with any regularity and have moreover searched enough to find me in the first place. While this has the significant advantage of a strong initial auto-filtering, it also has the crippling disadvantage that it's so slow as to be in the end not practical. I can improve on this a bit perhaps by selecting a few and simply immersing them more in Eulora/TMSR work directly, see where that leads. However, even at best, that'll be currently 1 or at most 2 people that I'd even consider at all so what's that going to do exactly anyway?

The low numbers above are not "too low" for what it is - if anything, they are actually quite good results I suppose. Given the natural scarcity of quality combined with modern artificial abundance of everything else, the above leisurely approach is really nothing more than playing the lottery and with very few tickets too. So no wonder as to results, but let's screw this semi-passive wait for repeated lottery wins and look instead for some more active and pointed ways to find the ones I care to find in the first place and to specifically aim the whole time at the most pressing need - help grow those who can actively take part in Eulora and TMSR.

The first obvious and most straightforward avenue is to go again to the local Uni but this time specifically aiming to choose some helpers, adjust, repeat and keep at it. I'm still mulling this part over mainly in terms of whether to spread the word and then simply set up some workshop right in their campus since a laptop and a few drinks is all it takes anyway. Alternatively or in addition I suppose I can even do the same at the local pub3 and it might even have better seats and better drinks than their caffeteria. The only hurdle here is really to reserve some time on a regular basis specifically for this (or similar public meetings basically). This would be prong 1: regular public workshops as selection grounds.

While the above should be anyway an improvement in terms of number of candidates seen at least, it still doesn't strike me as enough at all. And moreover, there are the hard limits of location and of how many can physically fit around me at any given time. Looking to the wide online space, there is of course plenty of room there and supposedly plenty of eager young hands looking for a place where they can matter too. A quick look around shows at least in theory more gaming/programming/learning forums than you can shake a stick at, so in parallel with the above, I'll have to set up additional time to trawl those systematically and see what really is there, if anything. I suppose a "come work with me on what really matters so that you matter too" is just as good a starting message as any and it's not written in stone anyway. This would be prong 2: systematic trawling of gaming/programming/learning forums and talking to all their members.

Speaking of the multitude of forums and learning platforms and courses and summer schools and hackathons and whatnots, it's worth perhaps mentioning that I'm not particularly worried about their huge number and supposed competition. They are many indeed but they are as far as I can see quite alike, a lot of the same thing under slightly different wrappers, pretty much like all the latest and bestest "innovations" - at this stage they really seem to me more of a way to drown the few young ones that look for meaning than to actually help them in any way. For all the hype that seems to be around pushing and shoving youngsters into computing, from where I sit it really looks increasingly more like pushing and shoving them towards becoming the slaves and guinea pigs of tools and not at all their masters. So those who want the first are plenty served while those who want the last (and might not even know yet how to say it) are more starved than ever. The same situation shows in schools too in fact and to the extent that those looking for meaning will do just about anything to stick with it once they finally find the slightest shred of it.

All the above mulling out of the way, the next main step is to move my schedule around again and as soon as possible to make space for all of the above even if it's only a couple of hours per week, as long as it's every week. The mountain of work seems to only grow so that's not easy and it'll take a while to readjust so that I don't otherwise drop any major ball. But while this readjustment is ongoing, I'll be able at least to mull it all a bit more in case I can add to the list above and even cut out more clearly some tasks that I can drop newcomers into since that's the fuzziest part for now - there's quite a steep climb at the moment to everything I'm in and that's not really ideal for someone new and green. Still, the ideal is never available, so whatever it is, they'll follow along as best they can and that's what it will always be.

  1. While I can always go "why didn't I write the rest too?" there is this fact that writing takes time too and at some point I can either spend my limited time on doing or on writing about doing/having done it. No matter how I go about it, there will always be some amount of selection as to what gets written and what doesn't. This being said, there is as always plenty of space for doing better at this, certainly, especially since I know very well how much worse it was before I specifically set about to make it better, step by step. 

  2. One just went off last year to study Medicine for instance, am I going to consider that as a waste now or what. 

  3. Cafes haven't yet sprouted right on my doorstep and I'm not going to go to the town centre for this sort of thing just to be somewhere more crowded and noisier.

My Talk of Bitcoin at Reading Uni

Filed under: Outreach — Diana Coman @ 11:01 p.m.

As mentioned already in the logs1, today I gave a talk for students at Reading University (UK) about Bitcoin. Following the very useful advice from the forum, I centred my talk on "What Is Bitcoin?" and then I built on that with a discussion of actual innovation in Bitcoin (WoT, V, Deedbot) as opposed to the attempts at subversion of Bitcoin ("blockchain technologiezzz") that are usually touted about as "innovative!!" by all those "involved" through mere talking and repeated mentioning of all the buzz words in whatever happens to be the current consensus-approved sequence. Since there is no recording of the talk2 I decided it's best to do this write-up now, while everything is still quite clear in my memory. Who knows - it might help someone else who is looking to actually understand this Bitcoin thing rather than just copy/paste the most commonly copy/pasted stuff.

Initially the University had this bright approach to schedulling of talks and rooms so that they could not even guarantee that I'd have some sort (any sort!) of board on which to write during the talk and so I decided to make the most of it and make some supporting slides, despite the fact that I rather hate doing those things. Nevertheless, I've made them now so you can download the slides for this talk - just be aware that they are meant precisely to support the talk not to replace it so they don't actually contain even 10% of the talk, they just help *illustrate* what I say. So no, here as everywhere else, you can't really replace the person doing the talk and not see any difference, such is life, totally unfair. I'll try though to summarize in here the main ideas I covered - keep in mind that the whole talk was 90 minutes, of which I'd say about 30 minutes were Q&A throughout (i.e. not all at the end, as I took questions as and when they were able to actually ask something).


After an initial brief presentation of myself and Minigame establishing some basis on which I am actually giving this talk, I collected the existing "definitions" that students had about Bitcoin. As expected, they were not much in terms of meaning but surprisingly enough they were also rather difficult to extract - perhaps shyness or in a more optimist interpretation some well-placed notion that no, they don't actually have any idea what the thing is. Anyway, for the record, I got only two definitions: "a very volatile currency" and "an immutable ledger of transactions." So I noted that those touch a teeny tiny bit on what Bitcoin has in common with "currency" and "ledger of transactions" respectively while missing at the same time the much wider part of what is actually new, different and essentially disruptive about it. And I noted that the only way to actually get an idea of a complex notion (such as Bitcoin) as a whole, is by starting from its basic principles and following their characteristics and implications. So without further digression, I moved on to enumerating the 4 basic principles of Bitcoin (asymmetric cryptography, databases, peer-to-peer (p2p) and anonymity/pseudonimity) and then presenting each of them in turn.

For explaining asymmetric cryptography, I used Mircea Popescu's excellent approach of starting with the simple example of obtaining the 2 prime factors of a given number vs obtaining the number itself from those 2 prime factors when they are known. I took though rather bigger numbers because my audience was - it is to be hoped at least - made of people able to use their computers for such a task at short notice (I hope!). Based on this, I introduced the notion of public and secret (private) key, using the slides to graphically build up the whole thing piece by piece, aka keys, arrows, locks and all that bling. Basically I showed them a mini animated cartoon, what! And I'd say it worked - I could clearly see some ears pricking up!

Following on from the above, I discussed how that makes it possible to send messages without divulging the content but also without divulging the intended target either! Cue more animated cartoons with people simply trying to decrypt messages from a pile until they find the one (or at least one) that they *can* decrypt with their private key - hence, if they can decrypt it, then (and only then), it is meant for them! At this point they actually started to sit straighter and even nod from time to time as it - apparently - made sense. I finished this first part with a summary of what I had said so far, essentially the slide behind me in that picture.

The database and p2p principles I covered much faster as it was really just the main ideas that were of most interest to me for the task at hand: a database is essentially structure applied to data and that means any structure; p2p allows participants to find and obtain all the different parts of information out of a given set, without having to rely on any central authority /middle man but simply by communicating and interacting with the other participants. Nevertheless, p2p was also good for another mini-cartoon to illustrate that one needs to be able to assess what part of the whole they might have at any given time, what parts they are missing and to what degree a proposed part is what they are looking for.

After this brief interlude of databases+p2p I got back to building on the asymmetric cryptography introduced earlier aka introducing anonymity and pseudonimity. As the students were by now rather intently listening, I asked them what they could tell about those 3 messages on slide 30: there are 3 signed messages (encrypted with secret keys) of which 2 verify (decrypt correctly) and one doesn't verify with one given public key. After a few hesitations and false starts, they actually got it - yes, one can say that both that decrypt correctly were actually encrypted with the *same* private key! So I took this further and pointed out that this implies authorship (the one controlling the pair of this public key is the author of the first 2 messages), continuity (whoever signed the first message, also signed the second) and repudiability - one can easily prove that they did NOT sign the 3rd message! All very useful things since together they allow one to obtain pseudonimity - in other words, to have a way of gaining authorship and continuity without having to give up privacy and mix up in there personal information such as date of birth or where they hang out with friends on a Saturday night. So no more of "verify your identity by giving us the keys to your house and generally whatever else we might think of asking". Instead, pseudonimity by means of public/private keypair - one neat and simple way of enjoying the results of your work (aka building your reputation) without having to give up more private information than you choose to. This was the first time I mentioned reputation and I took the time to give a few examples since I was preparing the ground for the WoT later on. Judging by the large amount of questions that the WoT sparked, I'd say it hit home.

Putting everything together, I showed this boring slide 36 with classic bullet points. To make up for it and to check to some extent how much of the head-nodding actually meant some sort of understanding, I asked the students to identify in that definition what exactly "caused" each of those main characteristics listed there. They were fine with p2p -> no middle/central authority and they worked their way on pseudonimity. I explained the other two (reputation vs blind trust; irreversibility) in more detail since there were some important aspects there that weren't apparently all that obvious - including the "trust" in banks and governments and parents and what-not. Basically when many still trust without even realising that they really just ..."believe" and nothing more.

For the next step, I pointed out that innovation with/in Bitcoin is simply something that *maintains* all those main characteristics of Bitcoin while attempting otherwise to adapt the world ("how things are done") to it and NOT the other way around. By contrast, anything that tries to chip away even in the slightest at *any* of those main characteristics is nothing more but an attempt at subversion. As soon as one tries to change Bitcoin to fit the world ("what people expect/need/want"), one is - whether they admit it or not, whether they know it or not - trying to subvert Bitcoin, not innovate with it. So the difference being clear and easy enough to make hopefully, one can tell for anything whether it's innovation or subversion and they can then *also* tell whether the author is at least honest about it! At which point of course, they can therefore update the reputation of this author... even quite publicly if they are using the WoT!

From this point on I went online to show the WoT and V directly, exploring it a bit and discussing the actual meaning and use of the WoT and then linking it to deedbot and the voice system + wallet in #trilema. By this point there were several hands raised at the same time so questions started to really pickup. Quite a good number of questions focused on the "but it's not fair" aspect of an existing WoT + a signed-patches-only V:

  • So a newcomer needs to trust implicitly the deedbot owner in order to get into the WoT?
    • No, a newcomer needs first to find at least one person in the WoT who is willing to give them a rating. Unless and before they do that, they are just not part of the WoT and therefore there isn't much that they can do really. This is NOT meant to be (and nothing can be) a replacement for talking to people or getting to know people!
  • But then it's not fair for those that are not in the WoT!
    • Sure, life is not fair, nor will it ever be fair. Yes, it can be hard to get in the WoT if nobody knows you. So make yourself a key and start building up your reputation so that people CAN get to know you!
  • How do I know you did not rate yourself?
    • You talk to those people who rated me. If you can't talk to them, their rating is meaningless for you anyway. And yes, one can make as many "identities" (aka private keys) as they want to but remember that building up each of them takes time and effort. So why exactly would I waste this time and effort in bogus identities instead of increasing my real reputation?
  • But what if everyone negrates me for a tiny mistake I make in a patch and I can't participate to the community anymore3?
    • What of it? You TALK to them and see what you need to do to get them to change their rating; and if they are indeed as unreasonable as you assume them to be then why would you actually want to work with them?
  • Why isn't the WoT stored in the blockchain so that there isn't a "single point of failure" in the person owning deedbot?
    • You are confusing there the WoT with its *representation*! Deedbot simply stores a representation of the WoT but it is NOT the WoT, nor does it own the WoT. It is participating people who actually make and own the WoT. So if deedbot goes away or its owner turns rogue -as it actually happened with assbot before4 - the WoT simply moves/splits/migrates following the people. The ratings I give are neither fixed in stone nor anyone else's property and it is always and everywhere the people that matter, not the bots. And for that matter there can be *any number of WoTs*, what.
  • But what if the owner of deedbot cheats with the ratings?
    • Well, how exactly? People who gave those ratings know what ratings they gave and they will shout/negrate as soon as they notice any foul play. As for "bots" - what of them, their ratings are worthless since nobody rates *them* (and pure circular ratings you to bot and bot to you won't get you anywhere really, at least not with any sort of thinking people, no).
  • Why is the WoT implemented through deedbot, with a central model? Wouldn't it be better5 to rely on the blockchain only for the WoT so you don't have to trust a single person?
    • Why would the WoT need the blockchain? Ratings are NOT immutable. And at any rate, I'd much rather trust a person (who I can negrate if things go wrong!) than a... network as a whole (which for that matter is not even all that trustful, read about mining cartels to start getting some idea on this matter). Once again: there is no substitute to talking to, interacting with and ultimately trusting (or NOT trusting) individual people!
  • But what stops deedbot's owner from running with all the money?
    • Nothing can ever stop anyone from doing what they want to do. But the incentives here are stacked *against* this: his considerable reputation is on the line; and he can much more easily earn money AND increase his reputation by simply charging a fee for services rather than running away with the piggy banks. It's the same with any sort of contracts too, really: what stops the other party from breaking their contract? "The law!" No, the law doesn't and can't *stop* anything. You may trust some particular state that it will enforce that law and therefore give you some compensation for the breach of contract but it is just that - trust, blind-faith.

There were in fact many other questions but those are the ones that I think are rather usual so the answers can help others perhaps as well as the students who asked them this time. Obviously, the answers given above are those given at a talk - without the time to go deeper into details and without the luxury of linking related logs/posts from the abundant existing materials. I still did point out to students that there is much more to read on the subject both in the logs (which I demonstrated a bit) and on the TMSR blogs but whether they will do any reading of this sort or not is entirely up to them - since the benefits to reap for doing so as well as the losses to enjoy for failing to do so will also be for each of them personally and only for them.

All I can say is that I'm genuinely rather curious whether any of them gets to actually register a key and do something with it, now that they nodded at the talk, they asked the questions, they came at the end to me to say that they liked the talk and now that they have in front of them this opening, this way to get into it all6 - for as long as they actually have it, of course, since nothing is for ever!

  1. Yes, that's where pretty much everything worth the mention is... mentioned. Where else? 

  2. And barely any photos as the prof I asked to take some photos followed the talk so intently that he...forgot to take any! So he had to take a couple at the very end, while students were still asking questions, what can I do. 

  3. I let pass the whole community participation as there were bigger fish to fry this time. 

  4. Yes, I did give them the summary of the #bitcoin-assets debacle. 

  5. I honestly think he just-about-said "fairer" 

  6. Yes, I did tell them about #eulora and #ossasepia and even that I will rate them if they show up and convince me that they were at the lecture. Not that it makes in itself a difference - those who would come would come and find their way anyway and those who won't still won't, I know that.
