Hollywood in the ’50s, ’60s and ’70s created a long string of cheap horror movies that never reached the top rating lists. However, some of them, despite being left mostly abandonned by their authors, are worthy of some renewed attention. In this context, it is interesting to notice that the Internet Archive has recently pointed to a nice list of these B horror movies. In there, you will find (available for free download):

• Attack of the Giant Leeches
• Attack of the Killer Mushrooms
• Horrors of Spider Island
• Killers from Space
• Bloody Pit of Horror
• The Satanic Rites of Dracula
• Werewolf of Washington
• Killer Shrews
• The Giant Gila Monster

In the year 1956, “the Dutch graphic artist M.C. Escher made an unusual lithograph with the title ‘Print Gallery’. It shows a young man viewing a print in an exhibition gallery. Amongst the buildings depicted on the print, he sees paradoxically the very same gallery that he is standing in.”

The term was coined by the poet and columnist Nico Scheepmaker at the end of the 1970s. It is named after Droste, a Dutch brand of cocoa, whose box has a picture of a nurse carrying a serving tray with a cup of hot chocolate and a box of the same brand of cocoa.

It is always a bit difficult to actually think about doing backups. Either you spend too much time thinking about it or you forget about it. For Windows, I found a nice free utility program: FileHamster from MOGware.

This small utility will allow you to automatically backup every single file you save or modify. FileHamster will create a full history track of your activity without even the need to think about it. It acts immediately (you don’t have to wait for a daily backup), and keeps everything. Of course, you need some free disk space, but it’s so much of a relief…

Pink flamingo (Phoenicopterus ruber, Flamant rose). Brazil, 2007.

While everybody is speaking about downloads under surveillance of law enforcement forces and **AA groups defending the copyrights of music and cinema, I wondered where the download addicts were going now to get their load of big files.

I looked into the P2P networks heavily protected by a strong encryption and supposed to guarantee the anonymity of their uses (often named darknets). this claim seems to be well defended, but the available contents are limited and strongly influenced by the fight for liberties (and sometimes against the most paranoid conspirations) and very marginal behaviours (pedophily is really more present there than in the more common Internet you and me use everyday).

But I was also directed toward the Usenet newsgroups. It is clear that a large number of users are living a free life far from the preening eyes of most external observers. As a matter of fact, if you download from your ISP’s news server, the data flow is only visible by yor ISP and yourself. Nothing goes into the open Internet. Of course, some ISP decided to limit access to some of the newsgroups, but choice is still quite large and your tranquility is much more preserved than on a P2P network (and less than on a fully anonymous darknet).

What tools do you need to browse the newsgroups? A little more technical attention than on the simplest P2P networks, for sure. But the tools are relatively easy to find:

• A Usenet reader able to correctly read the posts containing attached file. You have to remember that more of these files are actually cut in parts, attached one by one to different posts and encoded using standard but very specific protocols. The most convincing free tool -for me- was Grabit for Windows that seems able to decode nearly anything, grabbing parts from different messages and sticking them together in files or directories. Most important, it understands how to work with *.NZB files that describe all the parts, all their locations, etc. for one attached file set.
• A software tool able to work with *.PAR2 files that allow to run around the transmission errors (with the help of one sophisticated encoding, they can compensate for missing data or corrupted data, etc.) Here, I prefered QuickPar for Windows, one more free tool.

Note: Normally, Grabit doe sit all, but QuickPar for Windows still comes handy in case of failure.

The most impressive part of my tests has been download performance. 13 Mbit/s, I did not see this for a long time. The more because it was sustained for days (it goes down a little because of minor trafic jams at my ISP in the evening).

But you have to notice that if you look for a specific data content, newsgroups are not helping you. The way they are organized is favoring a lot the exploitation of very young content. If newsgroup search engines exist (Grabit has one that is partially submitted to subscriptions), the Usenet system will only host young data or data recently published.

Roseate Spoonbill (Platalea ajaja, Spatule rosée). Brazil, 2007.

It’s bit too slow to be a tough competitor, but it’s worth thinking about one more sport where the computer/robot is now actively playing against human beings.

Collared Plover (Charadrius collaris, Pluvier d’Azara). Brazil, 2007.

As I am writing this article, I am in Shanghai for a profesionnal trip (my company seems to believe that I can improve some things in our manufacturing plant of Pudong, in the suburbs of this big Chinese city). As an amateur photographer, I took some time for myself to look at some photo opportunities here. Two remarks may interest you too.

Shooting in Shanghai

The most obvious observation in this gigantic city of 17 million people is that the air is full of dust. And I mean it. Everybody notice it. The city is under permanent construction (or is it “re-construction”). Zillions of trucks are moving earth around to help build sky-scrappers all over the city. This and the overall industrial pollution makes it amazingly foggy.

I wanted to shoot a few photos; Don’t even think about deep landscapes (even from the highest buildings): On the clearest day, the sky is white and the visibility is limited to a distance surprising to even my pre-informed self.

However, Shanghai is one the modern world cities where night shots are a real pleasure. There is light and contrast everywhere: Buildings with lights from top to bottom, giant ads, displays of all kinds and all sizes, ligthed boats on the Huangpu river. So much light that you may even forget your tripod if your willing to shoot at high ISOs.

Buying photo equipment in Shanghai

OK! Shanghai is less attractive than Hong Kong, but China is usually a place where you can find photo bargains. In Shanghai, the place to go -apart from the usual electronics malls found all over the city, like in Pudong (South of Shiji Avenue)- is the big photo market at Luban Lu and Xietu Lu (in Chinese, “Lu” means “road”), that I found easly thanks to Internet (it is just North of Lupu bridge and Zhongshan N° 1 Rd, in Puxi).

You will find there anything for photo and photo activities. 6 floors of small shops. Of course, you will find camera sales on 1st floor (Canon, Sony, Nikon, Pentax, Sigma, etc.). But as in many Shanghai malls, the higher you climb, the better bagains you find (until you reach a level where most offers are presented in approximate stacks and packs).

Apparently, the risk of seeing fake products is limited, but it may be very difficult to find the difference between an original product and a fake one. However, I did not find any price obviously too-low-to-be-true (a sure mark of fake products), just a lot of good bargains and some less impressive prices. Apparently, prices are a little better than most Europeans prices (even taking into account an added VAT to be paid when returning home) with nothing Earth shattering. However, you must remember that haggling is standard practice here. Some advice:

1. Know the European price of the item you want to buy (not to be taken by a bad price in the heat of the moment),
2. Know the exact Euro-Yuan conversion rate (everything is paid cash in Yuans (or RMB) which is currently about 10 yuans for 1 euro),
3. Ask for the price in simple English (”for this, how much?”),
4. The sales people will show it on the screen of a desktop calculator. You can make a counter proposal just by typing a different value on the same desktop calculator (a 5% discount seems to be standard). If the sale is possible, a frank smile will be enough and an exchange of “OK” will be clear.
5. Always keep in hand the item you’re interested in. Don’t let the sales guy go to the back of the shop (to pack it, or something). There is always the risk seeing him/her returning with a different product than the one you paid for.

People are very welcoming and even customers proposed to assist me and shopkeepers not speaking English. Many people where genuinely interested in knowing where I came from, what I wanted to find, etc.

Speaking of bargains, I saw a few things that could interest Minolta and Sony DSLR lovers like me: The last 3 floors host a large number of second-hand shops of relatively good quality. Plenty of equipment from all the brands you could expect and a few more… Examples of Minolta second hand lenses:

• Minolta Apo G 300mm/2.8 for 17,500 RMB, including the original hard box and in good condition (a fair bargain if you don’t count VAT)
• Minolta Apo G 600mm/4 for 38,000 RMB, without the original hard box, but in perfect condition (60% of normal eBay price, plus VAT. A great bargain for a several kilos of glass and metal)
• Minolta 1.4x converter for 1,800 RMB, like new (a fair price)
• Sony 2x converter for 3,200 RMB (not so great, even for a near perfect piece)

So, you can dig and find a few good things. Or you can run for the shops specializing in lighting equipment (fourth floor). Or you can look for the designer’s Leica shop on the last floor. Or you can shop around for a half-priced tripod (all brands are available plus a few good local copies).

Conclusion, for now

Shanghai is a neat place to be if you love big cities and skyscrappers. Tourism is quite pleasant there and hundreds of thousands of expatriates (and more tourists from all over the world) have made the local people really welcoming.
