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.

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.

I don’t know why (maybe because I’m looking for them) but I seem to find plenty of posts about optimizing your photography of food. Let’s share some of the best ones here:

• First, a real collection of them in one place: Big and Tasty Food Photography Tips Roundup.

This was a little event a few days ago: Adobe launched its first beta version of the online PhotoShop under the name of Photoshop Express. As it was easy to predict, it’s not as simple as marketing would like you to believe and you cannot replace one by the other as most of the reviews hereafter will show you:

• Les Numériques (en français): would better use Picasa to share the images prepared with Photoshop Express, and would want to see Raw files management, curves and histograms, and masks.
• Ars Technica (in English): it is rahter a cross between iPhoto and Adobe Bridge, but they love the basic features and (including color correction).
• Baekdal.com (in English) : disappointed; This is not an image editor, by far - just a fun way to apply a few corrections/effects. Woudl rather recommend Splashup, he feels is superior.
• Photojojo (in English): This is certainly not Photoshop but it does very well what it offers (basic image edition/correction).
• LifeHacker: Not the Full PS Package, but Good Web-Based Editing
• Pixinfo.com (in Hungarian): Honest! I didn’t understand what they think about it…

To notice: Photoshop Express is free, limited to 2GB of online storage (easy to reach) and in English only for now.

But is it real or fake?

Star Trek nearly defined what a SciFi TV series is or should be. Of course, there is something slightly ridiculous to the coloured pajamas used by the actors to convince the spectator that they are in the far future with advanced technology. But despite all its drawbacks, Star Trek is still a must-see for all lovers of Science Fiction.

Starship Enterprise

Most people lost count of the number seasons aired for Star Trek (after the initial series, there were long-living extensions like Voyager, Enterprise, The Next Generation or Deep Space Nine) but CBS decided to offer free access to the first season on its web site: Star Trek: The original season. It was aired from September 8, 1966.

Synopsis

The story is set in the 23rd century. We follow the adventures of the crew of starship Enterprise under the lead of Captain James T. Kirk (William Shatner), his First Officer Mr. Spock (Leonard Nimoy, his logic and his pointed ears), and his Chief Medical Officer Leonard McCoy (DeForest Kelley). Exploring deep space, they meet a number of aliens, exotic civilizations and various adventures.

Many will remember the memorable “Beam me up, Scotty!” used by Captain James T. Kirk to call a teleportation back to the spaceship.

OK! If it was not enough to expect a couple of major announcements from Canon and Sony for the tough market of high-end digital cameras, there is another competitor appearing in the image.

According to Amateur Photographer, Samsung is preparing a Full Frame D-SLR camera to compete with Canon EOS 5D (or future 5D Mk II), with Nikon D3, with future Sony Alpha 900. We know that Samsung has a very good technology (shared with Pentax) and that the high-end market is calling for Full Frame sensors.

Nothing is certain, and we will probably have to wait until 2009, but things are moving fast in Korea too.

Everybody keeps hearing that those buildings built in Abu Dhabi are the most extraordinary ones because the architects have huge amounts of money flowing to build them. But, actually, it’s a world wide competition to create the most astonishing sky-scrappers and buildings. Here are my best finds in this huge category:

Vertical urban farm

Cubes piled in Singapour

More than 1000 flats for Singapour. Office for Metropolitan Architecture.
(more…)

When you build millions of small metal cans, you need awesome technology.

As surprising as it may be, I needed to inform you about one little bit of rumour that is currently appearing on the Internet: The next ‘flagship‘ digital SLR camera (hig-end camera based on a Full Frame 15- or 20-MP sensor) from Sony could well not be called Alpha 900 as expected by nearly everybody but rather Alpha 500. I don’t really believe it, but you never know…

The other possibility is that the Sony Alpha 500 is another new mid-to-high end camera product that nobody’s seen yet (a successor to the Alpha 700, already?) but it would be the source of some confusing thoughts. To be checked in the future.
