Amazon owned IMDB.com, a popular web database of movies and actors, is no longer accessible from China.

Why China Blocked IMDB

While there has been no official comment on why the IMDB site was blocked inside China, rumors on Twitter suggest that this documentary on the Dalai Lama and Tibet may have been the main reason for the block.

The film talks about Tibetans living in exile and their struggle to free Tibet. The film also contains scenes from Chinese occupied Lhasa (Tibet capital) and all this may have been enough for the censors in China to put IMDB behind the red firewall.

Other popular websites that are currently blocked in China include Facebook, YouTube, Flickr, Tumblr and Twitter. Wikipedia is only partially banned in China.

Wireless Networking (Wi-Fi) has made it so easy for you to use the computer, portable media player, mobile phones, video game consoles, and other wireless devices anywhere in the house without the clutter of cables.

With traditional wired networks, it is extremely difficult for someone to steal your bandwidth but the big problem with wireless signals is that others can access the Internet using your broadband connection even while they are in a neighboring building or sitting in a car that parked outside your apartment.

This practice, also known as piggybacking, is bad for three reasons:

* It will increase your monthly Internet bill especially when you have to pay per byte of data transfer.
* It will decrease your Internet access speed since you are now sharing the same internet connection with other users.
* It can create a security hazard* as others may hack your computers and access your personal files through your own wireless network.

*] What do the bad guys use – There have been quite a few instances where innocent Internet users have been arrested for sending hate emails when in reality, their email accounts where hacked though the unsecured Wi-Fi networks that they had at home. Wireshark is a free packet sniffing tool for Linux, Mac and Windows that can scan traffic flowing though a wireless network including cookies, forms and other HTTP requests.

How to Secure Your Wireless Network

The good news is that it is not very hard to make your wireless network secure, which will both prevent others from stealing your internet and will also prevent hackers from taking control of your computers through your own wireless network.

Here a few simple things that you should to secure your wireless network:
Step 1. Open your router settings page

First, you need to know how to access your wireless router settings. Usually you can do this by typing in 192.168.1.1 into your web browser, and then enter the correct user name and password for the router. This is different for each router, so first check your router user manual.

You can also use Google to find the manuals for most routers online in case you lost the printed manual that came with your router purchase. For your reference, here are direct links to the manufacturer site of some popular router brands – Linksys, Cisco, Netgear, Apple AirPort, SMC, D-Link, Buffalo, TP-LINK, 3Com, Belkin

Step 2. Create a unique password on your router

Once you have logged into your router, the first thing you should do to secure your network is to change the default password* of the router to something more secure.

This will prevent others from accessing the router and you can easily maintain the security settings that you want. You can change the password from the Administration settings on your router settings page. The default values are generally admin / password.

[*] What do the bad guys use – This is a public database of default usernames and passwords of wireless routers, modems, switches and other networking equipment. For instance, anyone can easily make out from the database that the factory-default settings for Linksys equipment can be accessed by using admin for both username and password fields.

Step 3. Change your Network SSID name

The SSID (or Wireless Network Name) of your Wireless Router is usually pre-defined as “default” or is set as the brand name of the router (e.g., linksys). Although this will not make your network inherently* more secure, changing the SSID name of your network is a good idea as it will make it more obvious for others to know which network they are connecting to.

This setting is usually under the basic wireless settings in your router settings page. Once this is set, you will always be sure that you are connecting to the correct Wireless network even if there are multiple wireless networks in your area. Dont use your name, home address or other personal information in the SSID name.

[*] What do the bad guys use – Wi-Fi scanning tools like inSSIDer (Windows) and Kismet (Mac, Linux) are free and they will allow anyone to find all the available Wireless Networks in an area even if the routers are not broadcasting their SSID name.

Step 4. Enable Network Encryption

In order to prevent other computers in the area from using your internet connection, you need to encrypt your wireless signals.

There are several encryption methods for wireless settings, including WEP, WPA (WPA-Personal), and WPA2 (Wi-Fi Protected Access version 2). WEP is basic encryption and therefore least secure (i.e., it can be easily cracked*, but is compatible with a wide range of devices including older hardware, whereas WPA2 is the most secure but is only compatible with hardware manufactured since 2006.

To enable encryption on your Wireless network, open the wireless security settings on your router configuration page. This will usually let you select which security method you wish to choose; if you have older devices, choose WEP, otherwise go with WPA2. Enter a passphrase to access the network; make sure to set this to something that would be difficult for others to guess, and consider using a combination of letters, numbers, and special characters in the passphrase.

[*] What do the bad guys use – AirCrack and coWPAtty are some free tools that allow even non-hackers to crack the WEP / WPA (PSK) keys using dictionary or brute force techniques. A video on YouTube suggests that AirCrack may be easily used to break WiFi encryption using a jail-broken iPhone or an iPod Touch.

Step 5. Filter MAC addresses

Whether you have a laptop or a Wi-Fi enabled mobile phone, all your wireless devices have a unique MAC address (this has nothing to do with an Apple Mac) just like every computer connected to the Internet has a unique IP address. For an added layer of protection, you can add the MAC addresses of all your devices to your wireless router settings so that only the specified devices can connect to your Wi-Fi network.

MAC addresses are hard-coded into your networking equipment, so one address will only let that one device on the network. It is, unfortunately, possible to spoof a MAC address*, but an attacker must first know one of the MAC addresses of the computers that are connected to your Wireless network before he can attempt spoofing.

To enable MAC address filtering, first make a list of all your hardware devices that you want to connect to your wireless network**. Find their MAC addresses, and then add them to the MAC address filtering in your router administrative settings. You can find the MAC address for your computers by opening Command Prompt and typing in ipconfig /all, which will show your MAC address beside the name Physical Address. You can find the MAC addresses of Wireless mobile phones and other portable devices under their network settings, though this will vary for each device.

[*] What do the bad guys use – Someone can change the MAC address of his or her own computer and can easily connect to your network since your network allows connection from devices that have that particular MAC address. Anyone can determine the MAC address of your device wireless using a sniffing tool like Nmap and he can then change the MAC address of his own computer using another free tool like MAC Shift.

Step 6. Reduce the Range of the Wireless Signal

If your wireless router has a high range but you are staying in a small studio apartment, you can consider decreasing the signal range by either changing the mode of your router to 802.11g (instead of 802.11n or 802.11b) or use a different wireless channel.

You can also try placing the router under the bed, inside a shoe box or wrap a foil around the router antennas so that you can somewhat restrict the direction of signals.

Apply the Anti-Wi-Fi Paint – Researchers have developed a special Wi-Fi blocking paint that can help you stop neighbors from accessing your home network without you having to set up encryption at the router level. The paint contains chemicals that blocks radio signals by absorbing them. “By coating an entire room, Wi-Fi signals cant get in and, crucially, cant get out.”

Step 7. Upgrade your Router firmware

You should check the manufacturer site occasionally to make sure that your router is running the latest firmware. You can find the existing firmware version of your router using from the router dashboard at 192.168.*.
Connect to your Secure Wireless Network

To conclude, MAC Address filtering with WPA2 (AES) encryption (and a really complex passphrase) is probably the best way to secure your wireless network.

Once you have enabled the various security settings in your wireless router, you need to add the new settings to your computers and other wireless devices so that they all can connect to the Wi-Fi network. You can select to have your computer automatically connect to this network, so you wont have to enter the SSID, passphrase and other information every time you connect to the Internet.

Your wireless network will now be a lot more secure and intruders may have a tough time intercepting your Wi-Fi signals.

Who is Connected to your Wireless Network

If you are worried that an outsider may be connecting to the Internet using your Wireless network, try AirSnare – it a free utility that will look for unexpected MAC addresses on your Wireless network as well as to DHCP requests. Another option is that you open your router administration page (using the 192.168.* address) and look for the DHCP Clients Table (it under Status > Local Network on Linksys routers). Here you will see a list of all computers and wireless devices that are connected to your home network.

*It is also a good idea to turn off the router completely when you are not planning to use the computer for a longer period (like when you are out shopping). You save on electricity and the door remains 100% shut for wireless piggybackers.

**If you ever want to let a new device connect to your network, you will have to find its MAC address and add it to your router. If you simple want to let a friend connect to your wireless network one time, you can remove his MAC address from the router settings when he or she leaves your place.

After nearly five years of loyal service, Mininova deleted over a million torrent files when it partly shut down its website a week ago. What remains are a few thousand torrents that were uploaded though its content distribution platform, which only lists uploads by approved users.

Mininova was forced to take such a drastic measure following a negative verdict in their court battle with the local anti-piracy outfit BREIN this summer. The torrent indexer was told by the court to remove all infringing torrent files from its index. This was technically unfeasible according to the Mininova team, who were left with no other choice than to remove all torrent files uploaded by regular users.

This move resulted in the deletion of more than a million torrents, many of which were not infringing any copyrights at all. As expected, the consequences of this decision for Mininova traffic, as well as the number of searches and downloads on the site, are disastrous.

In just a few days Mininova traffic plummeted by 66%, from well over 5 million visits the day before the torrents were removed, to just 1.8 million yesterday. If the downward trend continues at this rate, the site will have less than a million visits a day a week from now, throwing it out of the top 10 most visited torrent sites that it led for two years in a row.

Even more striking perhaps is the drop in downloads and searches. As can be seen from the graph below, the number of downloads dropped from over 10 million a day to just 371,424. The number of searches went down from 10 to 3 million, a less steep drop than the downloads, probably indicating that not everyone is aware of the reduced number of torrents on the site.

So what next?

There is no doubt that Dutch anti-piracy outfit BREIN will be proud of their accomplishment, but aside from ruining Mininova business it will not have a significant impact on the overall volume of BitTorrent traffic. As always, new sites emerge by the dozens as old ones are shut down and users quickly adapt to the new situation.

A network engineer at a major Aussie ISP has confirmed that Mininova partial shutdown has had no noticeable effect on traffic volumes. I didnt notice any reduction in [torrent] traffic when The Pirate Bay went down. It hard to see how thered be any significant change from Mininova withdrawal.

That said, the ‘end of Mininova does leave a scar behind. For years most torrent indexers heavily relied on torrents that were uploaded to Mininova. With over a million user-uploaded torrents, the site was without a doubt the main torrent provider on the Internet. Although most of the torrents are still mirrored on other sites, Mininova role as content provider has to be taken over by others.

(PhysOrg.com) — Google has introduced its new experimental programming language Go, which aims to combine speedy application development through simplified coding with high-speed program execution.

Go is designed to serve as a systems language, rather like C or C++, but is extremely fast for development like Python, while still providing the benefits and security of being a true compiled language. The programming software is being released in an open source version because it is now at the stage of being powerful and useful, and because the open-source community is a great resource for developing better tools and libraries.

A principal engineer at Google, Rob Pike, said the new language made him more productive than ever. Go code is compiled almost instantly, and when compiled the code runs at close to the same speed as C, Pike explained. Unlike existing languages, Go is designed as a language for the kind of programs Google programmers write, and is optimized for massive scaling and for multi-core processors that handle many tasks in parallel. So far it has not been used in any of Google’s publically available applications.

Google’s Go began as a group 20% project in 2007, and full-time work began on it last year. In group 20% projects Google employees can spend up to 20% of their time developing projects that lie outside their normal responsibilities. Pike and colleagues developed Go because they were frustrated with the modern complexity of software development. Go is not designed for beginners, but is probably around the same level as Java in terms of difficulty learning it, Pike said. It is an object-oriented language with features such as true closures and reflection.

Go works with Google’s open-source technology Native Client, designed for running native code in web-based applications, but it is not known yet whether Go will be used in the new Google operating system, Chrome.

Google released another programming language, Simple, in July this year. Simple was a BASIC dialect designed specifically for developing Android applications.

Is XHTML dead? In July, the XHTML2 working group announced it would be dropping the spec and closing the book on XHTML2. That’s XHTML with a 2. Not XHTML.

XHTML is alive and well – it’s just not getting the overhaul that was intended with XHTML2. If you’re a developer or designer who writes markup, then you’re possibly already using XHTML 1.0 or 1.1, strict, transitional or otherwise.

I’d also be willing to bet that if you’re using it, you’re using it to make use of stricter validation rules: lowercase tags, double quoted attributes, self-closing tags (like
) and so on – right?

Equally, if you’re that type of designer or developer, you’re probably also not serving it as true XHTML. Quite simply because Internet Explorer doesn’t accept the application/ xhtml+xml mime type at all, which is a requirement for XHTML. This is old news, though.

The new news is that XHTML2 is dead. The idealist recommendation for the web didn’t make it. Possibly because of the lack of backward compatibility, possibly for lots of reasons – the web was hot with discussion on the loss of the spec; the why, who and “whoh!”.

However, there is hope. If you’re the type of person who likes the strict rules of markup design that runs everything carefully through a validator then you’ll be over the moon to know two things:

Firstly, HTML5 supports all the lowercase, self-closing tags, double quoted attributes – the works. And if you don’t like these things, it supports that too!

Secondly, if you absolutely have to have XHTML in your bag of tricks, XHTML5 will satisfy your thirst. XHTML5 is quite simply HTML5 + XML, ie all the normal rules of XHTML, like no document. write allowed.

* Google plumps for HTML 5 over Gears successor

For it to be XHTML5, though, you must serve it as application/xml or application/ xhtml+xml (which isn’t currently supported in IE). So HTML5 with lovely XHTML-style markup is the way I’ll be going.

Before we dive into what’s in HTML5 and what we have to do to get it going, though, I want to address the future: 2022. Aside from it being the year Queen Elizabeth II will celebrate her Platinum Jubilee (assuming she’s still around), it’s the date that’s been inappropriately linked with HTML5 in the minds of many in our community. It’s wrong.

In fact, HTML5 is ready to use today. So why the confusion? In an interview by Tech Republic, Ian Hickson, the editor of the HTML5 working draft, was asked to give a timeline of the HTML5 recommendation.

One date should have come out of that interview, but another, much further away did instead: 2022 – the date of the final proposed recommendation, which actually translates to: require at least two browsers to completely pass HTML5 test suites.

Let’s put this in context of another spec that’s taken a very long time: CSS2.1. CSS2.1 is CSS that I’m certain you’re familiar with. I’m certain you use it day to day, without any thought as to whether it’s a completed spec. Well, it’s been in development for over 10 years, and it has only just become a candidate recommendation (23 April 2009).

Even then, it still doesn’t have two browsers completely supporting it. Only Internet Explorer 8 supports the full CSS2.1 spec. Did that stop you from using CSS2.1? I suspect not. Will that stop us from using HTML5? It certainly shouldn’t.

HTML5 is available and ready to use today. In fact, the really important HTML5 date is October 2009. This is the last call for the HTML5 working draft. That means that issues with the spec, enhancements, bugs, anything – it all needs to be in and submitted and written into the spec for October (although it can go through reiterations, this is the main deadline).

The Web Hypertext Application Technology Working Group (WHATWG) is completely open for anyone to contribute their ideas and suggestions.

At the site, you can sign up to the mailing lists. You can communicate directly using IRC. And there’s even a complete log of all the IRC history. It’s all available from whatwg.org.

HTML5 in five seconds

So how do you get your markup to validate as HTML5? It’s super easy: you change your DOCTYPE from whatever it is now to this:

That’s it. It doesn’t require anything more than that.

Google is doing it already. Check out its homepage, written all in one line:
