Following a Parisian trail

Yesterday my parents gave me something they had found in a local shop: a copy of Fodor’s guide to France, dating from 1958. It has some nice turns of phrase, ranging from this comment in the section on dining out:

Wine-labeling was established by law at the end of the 19th century and is one of the few laws that Frenchmen take very much to heart.

to this piece from the chapter on shopping:

haute-couture

Then I came across a throwaway line in a paragraph about post offices:

There is a special fast letter service within Paris by pneumatic tube, delivery guaranteed within three hours of mailing. Ask for a ‘pneu’ form, costing 100 francs, or use one sheet of ordinary airmail stationery and an airmail envelope.

This intrigued me. As a child I had seen pneumatic tube systems in banks and building societies, and even in the occasional large shop; they allowed excess cash to be moved safely from the tills to the back office, in the days before credit cards and the invention of the ‘cashback’ concept enabled your customers to take the excess cash away for you.

But I hadn’t realised that pneumatic systems operated on such a scale in quite a few cities. The Paris network was the largest, incorporating, at its peak, over 400km of tubes. It featured in Truffaut’s 1969 film Baisers Volés (Stolen Kisses):

It operated for more than a century until it finally closed down in 1984, as reported here by the New York Times. To give some historical context, that was also the year in which Apple introduced the Macintosh.

Prague’s pneumatic post system wasn’t as large as the one in Paris, but continued operating (just) into the 21st century. And didn’t it have some beautiful control panels?

Molly Wright Steenson’s 5-minute Ignite talk is a good way to find out more.

Even though pneumatic tubes are now little used for the delivery of messages, they still exist in many locations for garbage collection – most famously on Roosevelt Island – and some companies, like Envac in Sweden are promoting them as the rubbish-collection model of the future. Our system in the UK does seem a bit primitive in comparison…

But, gosh! How did I arrive here from the haute-couture catwalks of Paris in the 50s?

I guess I just got sucked into it.

How to add a marker to a Google Map so that you can tell people, “It’s here!”

My friend Jo, who hails from those parts, sent me a link to this wonderful collection of Welsh cards.

Wrist recursion

My new watch can be used as the viewfinder for my iPhone camera. So, of course, the first thing it wanted to do was take a selfie.

IMG_1981

There’s a slight delay in the image, and in the shutter release, which means that the shot the camera actually took was after my finger had moved off the screen, but the image on the watch, from a second before, still shows it in place. If you click to see the full-size image, you can see a few levels of recursion (which says something about the resolution of this 1.5″ display!).

Beware of archiving on SSDs

Solid-state disks are wonderful things: quick, power-efficient, and mechanically robust.

But it’s worth noting that you shouldn’t use them for archiving data on a shelf, unless you keep them provided with power.

This KoreLogic blog post discusses the problem in terms of preserving legal evidence, and notes:

For client application SSDs, the powered-off retention period standard is one year while enterprise application SSDs have a powered-off retention period of three months. These retention periods can vary greatly depending on the temperature of the storage area that houses SSDs.

Now, I haven’t had a very good track record from my spinning drives in general, and I assume that any data on them is probably ephemeral unless they are in a RAID array. All of my computers use SSDs internally now.

But for offline archiving purposes, old-fashioned hard drives are definitely better.

The interesting result of the election

Figures are not finalised yet, of course, but these numbers strike me as revealing:

UKIP – 3.5M votes : 1 seat
Lib Dems – 1.5M votes : 10 seats
SNP – 1.2M votes : 57 seats

I’m not a political animal and have little interest in the overall results. And I’m no fan of UKIP.

But I am interested in algorithms, and it does seem clear that ours is rather broken.

Titanium nostalgia

Just over 14 years ago, in one of my first blog posts on Status-Q, I referred to the amazing fact that Apple, with the impending launch of OS X, was about to become, overnight, the largest vendor of Unix operating systems.

Unix was, up to that point, beloved of those of us working in universities and other scientific institutions, but was notoriously unfriendly to anyone not familiar with its highly-abbreviated command language. It sold in small quantities on expensive workstations, and the idea that the creator of the cuddly Macintosh was about to start deploying it on ordinary desktops seemed astonishing. In a little over a decade it would have evolved to be not only at the core of their mobile phones, but even on their watches!

Today, I fired up the Titanium Powerbook G4, the machine I was just starting to use at about that time.

For nostalgia reasons, I was revisiting the classic Mac OS, but back then I had been playing with the developer preview of OS X for a while, and when it was officially released I switched to the Mac and never looked back. I didn’t realise that I had made quite such a transition at the time, but a few months later I wrote:

At CNET there’s a comparison of Windows 2000 vs Mac OS X which comes out in favour of OS X. I’m a bit dubious about the higher OS X score for hardware compatibility, but it’s pleasing none the less. I currently use 3 machines on a regular basis. One runs Win2K, one runs Linux, and one runs Mac OS X. They all have their pros and cons, but if I could keep just one, I think it would be the Mac. I find myself pining for it when I’m using the others and, for all its current limitations, the reverse is seldom true.

P.S. I noticed a couple of other things from those early posts. The first is that they are both called ‘[untitled]’, because the convention of putting a title on blog posts hadn’t been established back then. The second is that neither of the URLs I linked to still work now. Never assume the web is going to be a long-term reference archive unless you control the site yourself!

The new Duracell

I had the honour of meeting Elon Musk briefly some years ago. Back then, he was just doing space exploration. There aren’t very many people for whom you could write that sentence – even without the word ‘just’ – but for him, its inclusion is entirely appropriate.

Now, he seems to be doing… well… everything that’s cool. I have since admired his orbital exploits, ridden in his cars, and, of course, bought a significant proportion of my purchases using Paypal – which helps pay for all the rest.

The latest product is apparently to be batteries – here’s the new press announcement – but these are not your average AAs. They’re wall-mounting.

models-powerwall

At 10kWh, these could run a lot of LED lightbulbs for a long time. Especially if you’re not also using them to recharge your model S.

They’re designed to make it easier for solar-equipped households to depend less on the grid, especially by time-shifting the peak sunshine energy at noon to the morning and evening, when there’s peak demand. That’s not simply about being green: just a few weeks ago, visiting friends were telling us about the ‘loadshedding‘ powercuts in Cape Town recently, where everybody got a scheduled two-hour outage each day to help cope with the insufficient power-generation capabilities in the country. This seems perfect for that, too.

Still, the next challenge Musk has to address is the really tricky one: the manufacture of solar panels which don’t ruin the appearance of the building to which they’re attached.

How to turn Apple Photos into a more powerful editor

Apple recently released OS X Yosemite 10.10.3, which includes their Photos app – the replacement for iPhoto.

This is unlikely ever to become my normal photo-management and editing tool, but it does have some nice features, and it has more editing controls than you might at first realise:

The previous holocaust

Tomorrow is the centenary of the start of the second biggest genocide in history.

Here’s what I wrote about it ten years ago:

Who remembers the Armenians?

My wife’s family, on one side, are Armenian. Her grandparents managed to escape the ruthless Turkish ethnic cleansing of 1915 by getting a boat to America, but most of the rest of their families were wiped out.

This is one of history’s biggest and yet least-known atrocities, so it’s refereshing to read Ben Macintyre’s article What’s the Turkish for Genocide?, which suggests that Turkey really ought at least to acknowledge its past before being allowed into the EU.

The question “Who remembers … the Armenians?”, by the way, was used by Hitler to reassure his generals that another holocaust they were embarking on would not be a long-term problem. It would be sad if any future dictators were still able to use the same reasoning.

Send some warmth to Norway!

The Norwegian Students’ and Academics’ International Assistance Fund have been making some brilliant videos to challenge the stereotypes that can creep into otherwise well-intentioned aid programmes.

Excellent stuff. The ‘Who Wants To Be A Volunteer’ one on their website is really nicely done, too!

Raises all sorts of interesting questions.

Many thanks to Simon for the link.
