I receive emails from Google about, among other things, 3D printing. These 3D printing emails link to pieces that mostly confirm my current prejudice about 3D printing, which is that it is an addition to the technological armoury of current manufacturers rather than any sort of domesticated challenge to the conventional idea of manufacturing being done by manufacturers. Far from making manufacturing less skilled, 3D printing is, as of now, making manufacturing more skilled. Which is good news for all rich countries whose economic edge is provided by being able to deploy an educated rather than merely industrious workforce.
Here is the kind of story that these emails link to:
… my colleagues and I have found a way to print composite material by making a relatively simple addition to a cheap, off-the-shelf 3D printer. The breakthrough was based on the simple idea of printing using a liquid polymer mixed with millions of tiny fibres. This makes a readily printable material that can, for example, be pushed through a tiny nozzle into the desired location. The final object can then be printed layer by layer, as with many other 3D printing processes.
The big challenge was working out how to reassemble the tiny fibres into the carefully arranged patterns needed to generate the superior strength we expect from composites. The innovation we developed was to use ultrasonic waves to form the fibres into patterns within the polymer while it’s still in its liquid state.
The ultrasound effectively creates a patterned force field in the liquid plastic and the fibres move to and align with low pressure regions in the field called nodes. The fibres are then fixed in place using a tightly focused laser beam that cures (sets) the polymer. …
The patterned fibres can be thought of as a reinforcement network, just like the steel reinforcing bars that are routinely placed in concrete structures …
In earlier pieces I have done here about 3D printing, commenters have compared the current state of domestic 3D printing with the state that domestic 2D printing had reached in the days of the dot matrix printer. Remember those? Maybe not. They disappeared from common view quite a while ago now.
The above description of miniature reinforcing rods makes me think that something like a 3D printing analogue to the 2D domestic laser printer may be about to emerge. Laser printers supplied, once their price had fallen to something domestically tolerable, unprecedented clarity and flexibility to domestic computer users. The process described above, and all the other 3D printing advances that those google emails tell me about, will, if all develops well, supply unprecedented internal strength, and hence just all-round quality, to cheaply printed 3D objects.
None of which means that specialised 3D printing by specialisers in all the various different sorts of 3D printing that are now coming on stream will cease to be a way to make a living, any more than specialised 2D printing experts have all now been run out of business by amateurs in their homes. (Quite the opposite – that link being just one for-instance of a hundred that I might have picked – I just happen to have particularly noticed taxis covered in adverts.) It is merely that, in the not too distant future, domesticated 3D printing may actually become seriously useful to people other than hobbyists and 3D printing self-educators.
However, even as supply gets ever cleverer, when it comes to domestic 3D printing there remains the problem of demand. As I asked in this earlier posting here (commenter Shirley Knott agreed): What 3D printed objects will be demanded domestically in sufficient quantities, again and again with only superficial variations (in the way that black-on-white messages on paper are now demanded) to make domestic 3D printing make any sense? No answer was supplied in those comments three years ago, and I have heard no answer since. So the above ultrasound-arranged reinforcing rods trick will almost certainly turn into just another manufacturing technique for old-school manufacturers to apply to their old-school specialist manufacturing businesses. Which means that this posting becomes just another Samizdata Ain’t Capitalism Great? postings. Which is fine. On the other hand, few can see killer apps coming, until suddenly they come. So maybe a future beckons, which sees us all eating out, but making other, inedible stuff in our kitchens.
The reinforced concrete reference also makes me even more eager than I long have been to see how 3D printing impacts on the world of architecture, architecture being another enthusiasm of mine. Postings like this one at Dezeen make it clear that this is a question that lots of others are wondering about also.
The Cold War ended a quarter of a century ago. Some are forgetting about it, others are never even learning about it. Many others are deliberately forgetting about the Cold War, because it, and how it ended, made them look bad. But the Cold War needs to be remembered. What it was. What it meant. And why it was such a good thing that the good side won and that the bad side lost.
Sights like this poster, I suggest, which I managed to photograph at Pimlico tube station yesterday before the train I was awaiting blocked it from my view, might help. It is advertising a German series now running on British TV, set during the final years of the Cold War:
I have not been watching Deutschland 83. Comments from any who have would be most welcome. If such comments materialise, I would not be surprised to learn that it contains many little touches of moral equivalence, inaccuracy, and deft little claims to the effect that the winners of the Cold War won it by mistake and that the losers of the Cold War lost it on purpose. I don’t know, but fear the worst on that front. (A little googling led me to this piece, which, with its typically snearing Reagan reference, does not reassure me.)
But meanwhile, the above poster struck me yesterday and strikes me still as a breath of fresh, clean, truthful air.
I particularly like the colour contrast. I further like that Marx and Lenin get blamed for this colour contrast. I like that there is barbed wire on the bad side but none on the good side, grim and grey sky on the bad side and blue sky on the good side, privation and militarism on the bad side and an abundance of tasty food, romantic pleasure and technological inventiveness on the good side.
Perhaps the makers of this poster – and if not them than at least some of those distributing it and displaying it in this country – thought that they were being ironic rather than truthful. Perhaps some of these people think that this poster does not so much present truth as mock the truthful opinions of people like me and my fellow Samizdatistas, for being “simplistic”. If so, to hell with such anti-anti-communist imbeciles. I prefer the truth about the Cold War and I rejoice that this poster proclaims that truth, especially to people who may not now be aware of it.

Like Michael Jennings, I end my 2015 blogging efforts here at Samizdata with a clutch of pictures. Unlike Michael, I haven’t managed to do anything like this for every one of the last ten years. I did do something similar two years ago, but this time last year my retrospective attention was concentrated on the speakers at my monthly meetings, without any pictures of them.
I began my 2015 in France.

“Fear not,” said the angel at Christmas, “for, behold, I bring you good tidings of great joy, which shall be to all people.” Indeed. There has never been a better time to be a human being.
– Dan Hannan writes in Conservative Home that 2015 was the best year in human history, and 2016 will be better yet.
Libertarians are now the optimists about the human future, and collectivists are the pessimists. Libertarians know how to make the world better for humans and are doing this, by resisting and (wherever possible) rolling back collectivism. Collectivists never did know how to make the world better for humans, but now not even they believe that they know how to do this. All they can now do is fabricate catastrophe and demand that keeping human progress going be made into a crime.
So, as I regularly do, I read a recent posting at Mick Hartley, which is about what nutters the rulers of Saudi Arabians are, spreading the theology of bedlam and then griping when people do what the theology says, and all the while blaming the Jews for their own ridiculousness.
And then I read this comment underneath that posting, from someone called “Graham”:
Ironically, it’s the Israeli-Saudi alliance behind the QSD that’s defeating ISIS.
QSD? Quesque c’est?
I found my way to this piece (I love the internet):
These are Kurds, Muslim Arabs, Turkmens, and Syriac Christians. …
… which, to me: sounds good, sounds bad, sounds don’t-know, and sounds good …
… About two weeks after this EXTREMELY disparate group was created, it launched the most successful series of offensives in the entire five-year Syrian civil war. The US immediately began arming the QSD, and the Turks suddenly stopped complaining that the Kurds in this new army were up to no good.
This guy goes on to say (I think) that the “Muslim Arabs” are Tunisian special forces, the Tunisians having become very pissed off with ISIS for having recently destroyed their tourist industry. So those Muslim Arabs sound semi-sane, or as semi-sane as Arabs ever are.
And I also found my way to this piece of Kurdish Daily News (Kurdish Daily News, to me, sounds good) which says:
Syrian Democratic Forces (QSD) has released a six-day balance sheet of the operation they launched against ISIS gangs in the rural areas of south Hesekê on October 31.
During the first six days of the operation, an area of 350 square kilometers has been cleared of ISIS gangs; which involves 36 villages, 10 hamlets, 2 gas factories, 3 quarry areas and some guard posts near the borderline.
The operation has thus far left 196 members of the gangs dead, 99 of whom were killed by QSD forces and 79 as a result of airstrikes by jets of the international coalition.
Part of my daily reading these days consists of Instapundit, and people linked to by Instapundit, telling me that the Middle East is going totally to hell, and that US Middle East policy now has no redeeming features at all. But I am unpersuaded that the answer to the Middle East’s many problems is for the Middle East to be totally conquered and then micro-managed by the USA, with everyone else just standing around and either waiting for their chance and getting it, or else hoping for the best and not getting it. US policy now seems to have been to back off, wait for some Good Guys to emerge out of the mess, and then when they eventually did, to back them with a few guns and a few missiles and a few airstrikes, but not with a huge US army stomping about making friends-that-are (and then abandoning them following an election) or friends-that-aren’t and enemies-that-are, and generally crowding out the best local answers. Is that – “leading from behind” (i.e. not actually leading at all) – such a very terrible idea? It sounds like a rather better idea than earlier ideas have been. Whether President Obama started out wanted that policy, I really do not know, but that now seems to be what is happening.
This more recent posting at Mick Hartley says that if QSD beats ISIL, the big winner could end up being al-Qaida. But might not QSD first defeat ISIL, and then might not QSD, or something closely related to or descended from QSD, then turn on al-Qaida and defeat al-Qaida also?
But what the hell do I know? Comments anyone?
Ever since the universe obliged me by inventing digital photography, I have been taking a lot of photos (only click on that if you really want to see some of my photos and are willing to wait). One of the sorts of photos that I like to take a lot of is photos of other people taking photos. I particularly like it when they are holding something in front of their face, like a camera or a coat or a bag, so that I can then stick my photo of them photoing up on the internet without them being very recognisable, by which I mean face-recognition-software-recognisable.
And earlier this month, I took this photo, of a lady on Westminster Bridge, taking a photo of another lady. Well, that’s what I at first thought, but later I realised that she was almost certainly videoing the other lady. That’s because in addition to holding up her iPhone (over most of her face) she was also holding up a hand-made teleprompter, covered in text:
I did a few months of schoolboy Russian about half a century ago, so I am pretty sure that this is Russian. But what does it say?
Here it is closer-up and more easily readable, with the blueness removed:
So, is this harmless tourist guidance? Viciously mendacious Putinite propaganda, full of nonsensical lies about the Ukraine? Some kind of personal message? I have enjoyed wondering, but now I would really like to know.
I am sure that at least one of our most knowledgeable and obliging commentariat can knowledgeably oblige with the answer.
I am reading the latest piece at Libertarian Home by Nico Metten, a man whose thoughts and thought processes I am coming greatly to admire. I am only a tiny bit into this piece so far, but already I have read this very lucid observation, which I think is worth passing on:
A prominent libertarian advocate of consequentialism is David Friedman. Consequentialists argue that it is useless to deal with philosophy or morals, as these are very unclear and subjective. What matters are the outcomes of certain policies. As long as the outcomes are ok, the rest does not matter so much. People like David Friedman simply don’t seem to want to deal with philosophy and morals. They are uncomfortable with it. Because of that, they only deal with what they consider more objective, which in this case is economics.
Personally, I don’t have a problem with people getting into libertarianism through economics. Economics seems to play a major role in exposing the state and it can make a lot of converts. I myself have learned a lot from economists when it comes to questioning the state. Labelling this approach as consequentialist however suggests that this follows a distinct philosophy. And here I am not so sure.
To me it seems impossible to be a pure consequentialist. I would agree that results matter. However, how do we know which results are good results? It seems in order to evaluate results, one first will need an evaluation tool. This evaluation tool logically needs to come before the actual consequences and is therefore not consequentialist itself. If this is true, then consequentialism as a stand alone philosophy seems logically impossible. But how come intelligent people like David Friedman can think that they are consequentialists? Friedman clearly must have an evaluation tool. I think the reason for this is that his evaluation tool is completely tacit. It is there, but Friedman is not consciously aware of it.
Good point. I have certainly been vaguely aware of this point, rather as Metten says that Friedman must have been. But I have never read it spelt out quite so clearly and so explicitly. Or, if I have, I wasn’t paying attention.
I am now reading the whole thing.
Claire Lehmann describes some of the work of contrarian social psychologist Lee Jussim:
It appears that descriptive stereotypes are a crutch to lean on when we have no other information about a person. When we gain additional insights into people, these stereotypes are no longer useful. And there is now a body of evidence to suggest that stereotypes are not as fixed, unchangeable and inflexible as they’ve historically been portrayed to be.
So, it would appear that “we” make use of stereotypes exactly as I make use of stereotypes (or as I try to), as crude first approximations, rather than as the last word. Bigotry, it has always seemed to me, means not having no prejudices, but rather having prejudices which you are unwilling to alter, when faced with circumstances which do not fit your prejudices. And it seems that “we” think like that also.
Good to know. My thanks to Bishop Hill for telling me about this piece.
Having written all of the above (apart from the thanks to Bishop Hill), I see that the previous posting here is also about stereotyping.
If you are an anti-Corbynite Labourite, things are looking pretty grim just now:
By his disastrous widening of the franchise for electing the party leader, Ed Miliband has handed control of it to what a previous leader, Hugh Gaitskell, memorably denounced as “pacifists, unilateralists and fellow travellers” – people not only antipathetic to ordinary voters but anathema even to most ordinary Labour MPs. It will be hard, it may even be impossible, to get the institution back. …
Quite so, except that the people to whom the Labour Party has just been handed are not pacifists. They favour violence provided that it is inflicted upon Britain and upon civilisation by Britain’s and by civilisation’s enemies.
This is Robert Harris, in today’s Sunday Times, and dragged out from behind its paywall here.
Such chaos cannot go on much longer.. Those MPs who either defy a three-line whip to vote for military action against Isis, or who are permitted to follow their consciences in a free vote, may well prove to be the nucleus of a new party.
If that sounds apocalyptic then so is the mood of many Labour MPs: obliged to watch at close quarters day in, day out, the incompetent antics of a leadership that has no hope of ever winning a general election but which is nonetheless impossible to dislodge.
But if you are a Corbynite Labourite, things are looking pretty good:
Formed as a successor to the Corbyn campaign, Momentum is in the process of setting up governance arrangements to represent its supporters amongst the Labour Party membership as well as the wider social movement which is springing up. As it grows, Momentum will develop democratic governance structures at every level of the network.
That being from the Momentum website. However, I prefer this piece of Momentum propaganda, which I spotted recently in the tube:
Who knew that political feuding could be so glamorous?
Here is another Labour Party related picture which I took, when walking beside a disconnected and unnavigable canal (a certain creek springs to mind) in north London earlier this year. Did the person who threw this sign into the water know something that the rest of us did not, about the future of the Labour Party?
To be more serious, I am content to see the Labour Party reduced to a state of ruin.

Far leftists do not laugh to mock communism. They laugh to forget communism. They dismiss the mass murders, and the suppression of every right that makes life worth living with a giggle and a snort, and imply that you are a bit of a prude if you cannot do the same.
Then they throw a copy of Mao’s Little Red Book across the chamber of the House of Commons and look round with utter bemusement when no one gets the gag.

With thanks to Mick Hartley.
I hugely enjoyed this bravura exercise in self-promotion by Milo Yiannopoulos.
Sure, I work harder than everyone else, sleep less than everyone else (four hours, on average), I’m funnier, more charming, smarter, better looking and more modest than everyone else. But that’s not the whole story.
My technique isn’t some great contact book, or a crack team of cyber commandos, or some big secret social engineering secret. Nor is it even the fact that I’ve made myself social justice-proof by letting my flamboyant personality loose in public and never shutting up about black boyfriends. (They can’t get me on racism, homophobia or misogyny, so half the time they don’t even bother showing up to debate me.)
My secret is just this: I don’t exclude people. …
And much else in a similar vein. Or maybe that should be vain.
As I say, I greatly enjoyed this fireword display. More than any other recent piece of writing, this one reminded me of the most persuasively entertaining stuff that the hippy-lefties were saying and doing in the 1960s, in an earlier age of alternative media. Like Yiannopoulos, they only grew stronger with all the outraged attacks on them by third-rate establishmentarian bores. The hippy-lefties won. Yiannopoulos, as he says, is also now winning. Given that he calls himself a cultural libertarian, that’s all part of what I like about him.
But what do others think? I doubt everyone here likes this man’s way with words as much as I do. Maybe I like him because I have only recently started noticing him, and maybe after a while I’ll get bored of him. Perhaps so, but as of now, I want to know more. And you learn a lot about something, or someone, by watching people argue about it, or him. All comments – pro-, anti- or anything else- – will be gratefully read, by me at least.
