False Dawn, John Gray 1998.
As a subscriber to The Economist magazine, John Gray's 1998 book is an uncomfortable read: the main targets of his skewering are such Economist icons as free markets, liberal democracy and much of the Enlightenment project itself. Gray predicts the implosion of the financial system and describes the future as being one of many competing, and very different, capitalisms than the one the "West" has tried to spread around the world since the Second World War.
The book is challenging to many preconceived notions of the way the world works and what the future holds, and that makes it very thought provoking. Now that we've had a major financial inflection point (I could say crash), the book was worth another read.
For an even more thought-provoking and challenging book by John Gray, I've also read Straw Dogs. This book needs a re-read and then a post itself.
From the Postscript synopsis :
False Dawn argues that a global free market is not an iron law of historical development but a political project. The deep flaws of this project have already caused much unnecessary suffering. Yet a global economy modelled on Anglo-American free markets is the avowed goal of the International Monetary Fund and similar transnational organisations. Global markets are engines of creative destruction. Like the markets of the past, they do not advance in smooth, steady waves. They make progress through cycles of boom and bust, speculative manias and financial crises. Like capitalism in the past, global capitalism achieves its prodigious productivity today by destroying old industries, occupations and ways of life - but on a scale that is worldwide.
If you want to learn something and actually retain the knowledge, there's no point cramming - extensive and lengthy periods of solid study. You might manage to pass an exam, but after a few weeks or months (let alone years) you forget most of it. I speak from personal experience!
A post by Peter Evgan on using flashcards for learning reminded me that I really should do a post about this as well. I've been using the same application Anki as an aid to learning - and more importantly, remembering what I've learned.
Anki is a program which makes remembering things easy. Because it's a lot more efficient than traditional study methods, you can either greatly decrease your time spent studying, or greatly increase the amount you learn.
The secret to something like Anki is being asked a question (e.g. on the front of a "card") and trying to recall the answer (written on the back of the "card"). This act of recall (active recall testing) strengthens your memory. Another important element is something called spaced repetition: spreading the questions over time with a schedule to repeat based on how well you do in recall. This schedule, and the feedback you give on your recall, reinforces the memory and stops the knowledge fading away.
There's a real science and lots of research behind the spaced repetition study method, enough to really hammer home its utility. Some reading :
- Memorizing a programming language using spaced repetition software
Ignore the "programming language" title as this is generally applicable.
- The 20 rules of formulating knowledge in learning
As Derek Sivers says in the first link above :
.. memory research shows that the most effective and efficient time for a new fact to be remembered is right before you were about to forget it.
A tool like Anki tracks your learning and calculates the best schedule to reinforce the memory. I've been using it to teach myself the Vim text editor and it's helping enormously,
However, the key to this technique is creating the cards. You have to be a little careful here and make sure you understand the fact (or knowledge) you're setting down on the card.
Anki makes this all much easier. Not only is it free, it works on Windows, Mac, Linux, Android and iPhone. And another key feature is that you can synchronise the Anki state across all your devices.
The Anki manual introduction explains the system and describes why it works so well. I recommend you have a read and try it out. There's always something worth learning.
The last book I read was on paper, as is the current one. It's not a large paperback, so I'm not finding it too unwieldy to carry around compared to my Kindle, but I do miss one thing. On the Kindle you can select a word, press with your finger and pull up the dictionary definition. For those words you come across that you don't know, this is a great feature. Can't do that with a real book!
This is a big turnaround for me however because it is not that long ago that I would have sworn never to use KDE. I last tried it over 10 years ago and thought it had a lot of very rough edges, plus felt and looked "cheap". Alongside too many half-baked "K" applications and a ridiculous number of configuration parameters and settings, a significant part of it didn't work very well.
It's completely different now and the Debian Wheezy version I'm using (KDE 4.8.4, a few versions out of date now) not only looks fantastic but almost all of it works as expected.
I've had it crash once whilst messing with a particular desktop setting, but it restarted itself automatically and carried on from where it left off. In comparison, I booted Gnome 3 a few weeks ago, just to have another look, played with the ALT+TAB/ALT+` switching for a few seconds and it crashed the desktop. Unlike KDE, it didn't recover but logged you out, losing everything.
The desktop still has a lot of settings to browse but the control panel makes sense and it all seems properly integrated. There are still a few areas I don't properly understand, KDE activities being the main one, but you can ignore them until you feel like having a better look. Virtual desktops work as usual.
All in all, I'm really liking KDE. The developers are doing a wonderful job and the QT toolkit gets better and better. Definitely worth a look.
For people that want to have a play themselves, you can download a KDE live DVD (e.g. Suse do KDE well), boot from it and play without affecting or changing anything on your PC.
I finished Tess of the d'Urbervilles last Saturday afternoon, lazing about on Clapham Common on a lovely sunny afternoon in SW4. The Common's the nearest to a rural idyll we have in these parts.
Hardy's classic is a beautifully written book with much lyrical description of the English countryside and the people working in it. It's not the usual book I would read but perhaps a vague memory of Nastassja Kinski in Roman Polanski's 1979 film Tess (above) spurred an interest. Now I'll need to see the film.
Things begin with the traditional May day dance that the women and girls do every year and the book has a lot of this sort of disappearing country tradition :
And as each and all of them were warmed without by the sun, so each had a private little sun for her soul to bask in; some dream, some affection, some hobby, at least some remote and distant hope which, though perhaps starving to nothing, still lived on, as hopes will. They they were all cheerful, and many of them merry.
This sort of poetry infuses the book, with rich evocations of a non-existent world now. The machine (engine) might be rare but it has started to make its rumbling noisy presence felt. The rustic charm and Hardy's occasional written dorset dialect reminded me of the book Precious Bane by Mary Webb, something I haven't actually read but heard, as a superb BBC Radio adaptation a few years ago. Yet another book I need to add to the reading list.
A lot of the real power comes from Hardy's unflinching (for the time) look at the realities of working lives in the countryside. These are hard lives for men, women, girls and boys, with a lot of back-breaking work and hardship. No unemployment, health or housing benefit here. Tess is very strong willed and she's proud, and she also has a great joy in life that shines even at low points. It is this that makes you love her company so much.
In 1981, the BBC released a personal computer, the BBC Micro.
Although fairly expensive, they were quite popular - even more popular in schools and colleges (which got subsidies for them). This machine might have been responsible for the start of many (perhaps most) computer departments in schools!
There's a great YouTube video online from "Computerphile" called Original Elite on the BBC B that really takes you back to the "golden" age of the hobbyist computer in the UK. Lots of odd machines coming out like the Sinclair ZX80 (later ZX81 and Spectrum) and Acorn Atom. For the Atom, from Wikipedia :
At the time 256×192 was considered to be high resolution.
Richard Hill, now a physicist, talks in a very engaging way about the computer game Elite, a game that a lot of people fondly recall and one that introduced many to realtime 3D computer graphics. This was all done in 32Kb of RAM only and very little processing power compared to today. Not only does he demo the game (loading off cassette tape!), he also shows off a game he wrote himself inspired by it (coding in assembler, later C). Programming was much harder work in those days.
One thing he mentions near the end is that if he was starting out now, he might never have got into programming his game because of the huge number of distractions that make up the modern computer experience. Yes, we have much more power and they are much easier to use, but we also have a massively expanded number of distractions: emails, notifications, tweets, alerts, posts, streams, chats, messages, funny videos. The list goes on. The internet, for all its amazing usefulness, can also be a real time-waster.
It's hard to imagine the enthusiasm and joy this early tinkering can bring to a youngster. This early spirit is something that both the Maker Movement and the Raspberry Pi Foundation are trying to encourage again.
The Raspberry Pi (right) is a real computer and much more powerful than the BBC Micro. Complete with built in distraction though!
A provocatively titled post at Priceonomics called Is Wine Bullshit?.
That's a pretty good hook to draw you in, one reason being that there's already a little niggling feeling at the back of your head liking where this might be going.
A bit embarrassing.
There's much more like this, and it's hard not to feel a little schadenfreude as the author details them. But the article also touches upon how easily our taste senses can be fooled and how frail they can be. Easily fooled by simple expedients like a bit of colour added, rather like the red food colouring in the white wine.
I like a glass of wine but can't tell the various grapes apart, or know what region they're from. A lot of wine tastes fine to me but I can easily tell a bad one and I remember not to buy it again.
I've bought (so called) good wine, spending more than I normally would, and not been greatly impressed: I'm often more impressed with cheaper stuff. I've sometimes thought that this was due to my untrained palate and the need to cultivate it more. This is not something completely unheard of as I didn't use to like whisky until I "trained" myself a little. Maybe time for a bit more training!
