How to Cast Out Wi-Fi Intruders

Are you sure you�re the only one enjoying your home network? Here�s how to detect trespassers and block them from pilfering your bandwidth.

You love the convenience of your home Wi-Fi network, and guess what? You may not be the only one. If you haven�t adequately secured your network, it�s possible that others�your neighbors and various other passers-by, for example� are happily gobbling up the bandwidth you pay for.

Now, to be honest, you�re probably not using it all, and sharing is the neighborly thing to do. In fact, many routers will help you do just that (share, not be neighborly). Of course, it would be equally considerate if that guy down the hall offered you some cash to use your network.

That said, you may have some very good reasons for keeping your network locked. So, we�ve gathered some tips for finding out if people are using your 802.11-based signals as their own, and how you can block them out for good. (Note: Every model of wireless router has a different interface; even those from the same company are different. However, all have similar tools. )


Stop Broadcasting Your Name
Most Wi-Fi routers broadcast the SSID, or Service Set Identifier, by default. This is the name of your wireless network, and broadcasting it is how Wi-Fi-enabled devices, such as laptops and phones, find networks. You can, however, turn off broadcasting. It�s as simple as that. This is not foolproof (and it won�t prevent anyone who already knows
your network�s name from getting online), but it helps keep casual Wi-Fi stealers away. They�ll go for the lower-hanging fruit (e.g. another open network).

If users do have your current network name and you�d rather they didn�t, change the SSID. That will keep the crooks confused, at least for a while. Name it something like �LocalPrecinct212� and maybe they�ll be extra nervous about connecting. Change it frequently to keep them guessing. (This is usually a moot point if encryption is activated.) Keep in mind; if you do turn off broadcasting of your SSID, you make it a giant pain for yourself to add new devices to the network. It may not be worth the hassle.


Limit the IP Addresses
Networks use IP addresses to �talk.� A temporary IP address is assigned to each connected device by the router, using the Dynamic Host Control Protocol (DHCP). This can be a real time saver. However, if you want to take total control of your network, assign static IP addresses of your own to each network device�that means every laptop, phone, game system, and stray geegaw that uses Wi-Fi to get online. Unless you�re a total control freak, this can be more hassle than it�s worth.

The next option: Limit the number of IP addresses the DHCP will dole out. If you know you have six products connected to your network, then only let it assign six addresses. Remember that IP addresses cover wired and wireless products, so you have to include all of your Ethernet-based hardware in that list, which could include desktop PCs, TVs, game consoles, and more.

Finally, most new routers will do a DHCP reservation. This ensures that every time a device connects to the network, it gets the exact same IP address. Without reservations, the address could change. Keeping them the same makes it easier to communicate over the network, especially if you�re using a PC as a server for video to an Xbox or PS3, for example.


Block the MAC
You can check the MAC addresses listed for each device that is talking to your router against the MAC addresses physically stamped on the hardware you own. If you see a MAC listed that doesn�t match your equipment, then you may have a trespasser.

Next, find the MAC Address Filters in your router settings. Tell the router to allow only the MAC addresses you want. This requires entering a new MAC address every time you introduce a new Wi-Fi-based product to your network. Also, this isn�t foolproof, as MAC addresses can be spoofed with the right tools, but that�s usually something serious hackers, not casual wireless crooks, do.

Conversely, your filter may be set to deny access to the MAC addresses you list, like those you know are not your own but appear on your DHCP list.


Encrypt Those Airwaves
Naturally, the best method for preventing people from accessing your network while making it easily accessible to you and your friends is to encrypt it using the well-established Wi-Fi Protected Access (WPA), which comes in all modern network hardware.

However, you may have some old-school products lying around that only support the old and notoriously crackable WEP. You can use that, too, but it will leave your network a bit more vulnerable. It�s still better than nothing. Consider it a closed door with a broken lock; it�s better than no door at all.

You may also have products that use Wi-Fi Protected Setup (WPS). This works with WPA. Push a button on the router, then a corresponding button on a Wi-Fi product, and the two will auto-generate a nigh-invulnerable password that even you don�t know. You�ll just need a master password on the router. Not all Wi-Fi hardware supports this, so you may be better off picking your own super-strong password.


Perform Some Magic
Cisco Network Magic Pro 5.5 ($39.99 direct) remains our Editors� Choice for home-network activity tracking and more, including intrusion detection. It works with just about any home network (especially those with Cisco and Linksys routers) to help you get stronger and more secure connections. Plus, it gives you a glimpse of who shouldn�t be there in the on-screen network map.

In fact, the latest version uses a home network administration protocol (HNAP) to control security settings on most routers. When it works, it�s a quick way to fix security problems. Some other tools that could help you include Who�s On My WiFi and AirSnare.

Mobile Marketing: Location, Location, Location

A 2010 study by comScore suggests that almost 46 million mobile phone users have Smartphone� almost 20 percent of the market share of total mobile users.

Those numbers are enough for advertisers to start taking the mobile market very seriously. But what is the best way for advertisers and marketers to gain traction in this growing industry?

Increasingly, mobile content and applications are being targeted at a user�s location. A study from the Mobile Marketing Association (MMA) states that more than 25 percent of adults in the U.S. have used maps, navigation or other mobile phone services that automatically determine location. The same study indicates that nearly half of those using mobile phones have taken action on mobile ads.

Increasing the localization of customer targeting means more qualified traffic and better opportunities for conversion. Utilizing localized advertising in combination with interactive advertising offers users the very services they are seeking. That�s a winning formula.



Ready, Aim, Advertise
The great strength of the mobile ad is that it allows for very specific targeting of users. Advertisers who take the time to get to know their target audience will be able to reach out to a large group of consumers who are hungry for information about what is available in their immediate area.

At this point (and it should come as no surprise), the leader in location-based advertising is Google. Google has acquired a patent for using location for advertising, which sets it ahead of the competition. It allows users to bid on ad prices within a defined area and allows advertising from apps to directly correspond to a user�s location.



Hook
Anyone with experience managing PPC campaigns will find themselves in familiar territory when launching mobile ad campaigns. Just like PPC, mobile advertising allows you to set up a section for specific campaigns and, within those campaigns, create accounts for different brands, as well as their relative keywords.

In addition to choosing to advertise in search results or through the content network is the ability to select a specific area � obviously of importance to mobile ad campaigns. Mobile ad platforms will allow you to target geographical locations based on country, region and specific city.

For more highly targeted ads, advertisers can target specific mobile network carriers, devices and even markup languages. This allows users to control who they are advertising to, which, allows them to meet the needs of a destination URL, depending on the technological capabilities of the targeted device.



Line
Limited to very few characters, the mobile call-to action is a new art form. Mobile ad character limits on Google are 18 characters per line of text (two lines total), offering very few words to send your message. With so few characters available, highly targeted copy is very important. There are ways to increase your character count, however. For example, using AdMob, there is an option to select an ad targeted at �iPhones and other mobile devices with full Internet browsers.� This allows you to get a few more characters in both the title and body of your ad.



Sinker
You want your user to experience a feeling of success upon finding your landing page. Forget about the fact that users can zoom in on a mobile Web page. Create simple pages that display the information that benefits the user immediately upon landing.

Like any other form of Internet advertising, the mobile ad must reach multiple devices and screen sizes. With so many types of handsets, the ability to reach specific ones is absolutely imperative to a successful mobile marketing campaign. To market to more than just one of these groups, optimize multiple pages for each of the different styles.

A display on a Blackberry Curve is far different from that of an iPhone, for example. Phones have the ability to resize text but forcing users to take that extra step can be risky. Let your landing pages be as targeted to the users of specific devices as they are to the consumers you are trying to reach. A page that is not automatically readable or navigable with the information important to your consumers (delivering on the promise of the ad) could send users elsewhere.

Web developers can target specific phones to a certain degree by serving up different conditional CSS files. By checking the maximum width of the device�s screen, they can create usable layouts specific for the device.



Test for Success
Like other advertising campaigns, having several versions of an ad and a landing page is paramount to success. Continue to test different tactics and don�t be afraid to experiment.

Be aware that the ability to track mobile advertising campaigns is still somewhat limited. When checking an IP address for someone who visited your site with a Blackberry, for example, you will be seeing the Internet Gateway address, not the actual phone�s IP address. In addition, some phones don�t support cookies and others clear the cache on a regular basis. However, there are analytics solutions to help track ROI. Affiliates who find ways to measure the effectiveness of their campaigns will be miles ahead when the technology catches up to the needs of advertisers. And, by making use of the ability to target specific locations, you have already narrowed the criteria for analysis.

Mobile advertising, especially in terms of affiliate marketing, is in the early stages of its growth. There will be obstacles to overcome. But those who get in early and manage to grow with the developing technology will have a head start on their competition. The technology is already advancing in leaps and bounds. If you start now, you�ll be ready for the next development phases.

In addition to choosing to advertise in search results or through the content network is the ability to select a specific area � obviously of importance to mobile ad campaigns.

On the Nature of Software

Software is remarkable stuff. Sometimes, perhaps because we work with it all the time, we forget just how remarkable it is. Very little else in human experience is as malleable, allowing us free rein to exercise our ingenuity and inventiveness almost without limits. Also, with a very few exceptions, software is deterministic�the next state is completely determined by the current state, and (crucially) we have complete access to all of that state whenever we want it.

Compared to traditional engineering, we are spoiled. What do you think a Formula One engineer would give to be able to instantaneously stop an engine when it�s rotating at 19,000 revolutions per minute and examine every aspect of it in minute detail? To see the precise state of each component while under pressure and stress, for example, or to dynamically record the shape and position of the flame front within the combustion chambers during ignition?

It is exactly this kind of trick that we are able to perform with our software, which is why the empirical approach is particularly powerful when debugging.

Empirical Approach. Construct experiments, and observe the results. Empiricism relies upon observation or experience, rather than theory or pure logic. In the context of debugging, this means directly observing the behavior of the software. Yes, you could read the entire source code and use pure reason to work out what�s going on (and on occasion you may have no other choice), but doing so is usually inefficient and dangerous. You can track the problem down much more effectively by carefully constructing experiments and observing how the software behaves. Not only is this faster, but these observations force you to reexamine flawed assumptions in your mental model about how the software behaves. The software itself is the most powerful tool in your toolbox�allow it to show you what�s going on.

Debugging Is More Than �Making the Bug Go Away�

Ask an inexperienced programmer to define debugging, and they might answer that it is �finding a fix.� In fact, that is only one of several goals, and not even the most important of them.

Effective debugging requires that we take these steps:
1. Work out why the software is behaving unexpectedly.

2. Fix the problem.

3. Avoid breaking anything else.

4. Maintain or improve the overall quality (readability, architecture, test coverage, performance, and so on) of the code.

5. Ensure that the same problem does not occur elsewhere and cannot occur again.

Of these, by far the most important is the first�identifying the root cause of the problem is the cornerstone upon which everything else depends.

Understanding Is Everything
Inexperienced developers (and sometimes, unfortunately, those of us who should know better) often skip diagnosis altogether. Instead, they immediately implement what they think might be a fix. If they�re lucky, it won�t work, and all they will have done is waste their time. The real danger comes if it works, or seems to work, because now they�ve made a change to the source that they don�t really understand. It might fix the bug, but there is a real chance that in reality it is only masking the true underlying cause. Worse, there is a good chance that this kind of change will introduce regressions�breaking something that used to work correctly beforehand.

Wasted Time and Effort
Some years ago, I found myself working in a team containing a number of very experienced and talented developers. Most of their experience was with UNIX, but when I joined the team, they were in the late stages of porting the software to Windows. One of the bugs found during the port was a performance issue when running many threads simultaneously. Some threads were being starved, while others were running just fine.

Given that everything worked just fine under UNIX, the problem was clearly broken threading in Windows, so the decision was made to implement a custom thread scheduling system and avoid using that provided by the operating system. This would be a lot of work, obviously, but quite within the capabilities of a team of this caliber.

I joined the team when they were some way into the implementation, and sure enough, threads were no longer suffering from starvation. But thread scheduling is subtle, and they were still working through a number of issues that had been caused by the change (not least of which was that the changes had slowed the whole system down somewhat).

I was intrigued by this bug, because I�d previously experienced no problems with Windows� threading. A little investigation demonstrated that the performance issue was caused by the fact that Windows implements a dynamic thread priority boost. The bug could be fixed by disabling this with a single line of code (a call to SetThreadPriorityBoost( )).

The moral? The team had decided that Windows� threads were broken without really investigating the behavior they were seeing. In part, this might have been a cultural issue�Windows doesn�t have a good reputation among UNIX hackers. Nevertheless, if they had taken the time to identify the root cause, they would have saved themselves a great deal of work and avoided introducing complications that made the system both less efficient and more error-prone.

Without first understanding the true root cause of the bug, we are outside the realms of software engineering and delving instead into voodoo programming or programming by coincidence.

The Novatel MiFi 2200

The MiFi 2200 is a compact device, weighing 2 ounces and measuring 3.5 x 2.3 x 0.4 inches. It has a single power on/off button, and its faux metal front goes well with any mobile Apple product. It connects wirelessly with up to five Wi-Fi-enabled devices. You don�t need it with a 3G-enabled iPhone, but MiFi will bring broadband Internet connectivity to your iPod touch, a non-3G iPad, and other non-3G devices. You can even create a mini-LAN and piggyback off the MiFi�s 3G connection.

Setting up MiFi is straightforward: On your iPad or other WiFi device, go to your network/wireless settings and enter the SSID of the unit and the password. My unit had that information on a sticker on the bottom, but the SSID was wrong. Fortunately, my iPad found the correct SSID when it did a search, and within seconds, I was connected and back in business.

There are some downsides to the MiFi approach. Although it�s tiny, it�s still another device you have to carry around with you. It�s powered by a rechargeable battery that will give you about 4 hours of use and 40 hours of standby. If you plan on using it longer than 4 hours, you�ll have to carry its micro-USB charger with you. (You can use it indefinitely when connected to the charger.) You can also plug the MiFi into the USB port of a computer, but then only that computer can go online. Finally, although the device itself is inexpensive, the data connection is not.

Verizon (verizonwireless.com/b2c/mobilebroadband) offers the MiFi for as little as $50, but to get that price you have to sign up for a two-year contract ($60/month for the 5GB data plan or a $40/month for the 250MB data plan). Sprint (shop.sprint.com/en/shop, select the �Mobile Broadband Cards� link) offers the MiFi with �Instant Savings� and a mail-in rebate that make it free. You still have to sign up for a two-year contract, and the To summarize, the price of the MiFi 2200 really isn�t the issue�the cost of the data plans is! Over the life of a two-year contract you could end up spending $960-$1,440 for the 3G data service.

Ethics and App reviews

Editorial ethics have been around as long as the published word, but that might not be obvious if you read iPhone App review sites. Unfortunately, there are some Web publishers (and reviewers) that put quick cash in front of the best interests of their readers by taking money for reviews. Selling out is the critic�s cardinal sin, and the growing tendency to do so is why we established the Organization for App Testing Standards (a.k.a., O.A.T.S.).

O.A.T.S. is a group of iPhone App review publications that came together to raise the journalistic bar for the emerging world of iPhone application and game review sites. From our initial base of four sites, we have grown to 35 publications that have promised to serve their readers first, last, and always. Joining is simple, and every English-language site is welcome�providing they take the following Oath:

WE, THE CONSTITUENT SITES OF THE ORGANIZATION OF APP TESTING STANDARDS, have gathered under the auspices of O.A.T.S. with a common goal: to improve the quality of iPhone games and app criticism. While we applaud the great diversity of opinion now available to consumers looking for iPhone app reviews, it is clear to us that not all of these sources have put the best interests of the readership first. We hope to combat this by holding ourselves to a higher standard.


TO THAT END:
1.) WE PLEDGE to never mix business with editorial. We reject all forms of paid reviews, including �express reviewing� fees. Advertising on an O.A.T.S. site will have no bearing whatsoever on whether we decide to review an app, or on the nature of coverage we give it, when and if we do;

2.) WE PLEDGE to clearly mark all advertisements as such on our sites;

3.) WE PLEDGE to ensure that each of our reviews is as thorough, accurate, honest, and fully informed as possible;

4.) WE PLEDGE to promptly correct all factual mistakes in our reviews and to post an Editor�s Note when we do;

5.) WE PLEDGE that all editorial work appearing on our sites is our own;

6.) WE PLEDGE to allow disagreement, dissent, and complaint through reader commentary, and to never censor it;

7.) WE PLEDGE that all app reviews will follow the same process, whether a particular app is obtained via promo code, purchase, or ad-hoc distribution;

8.) WE PLEDGE that site promotions or contests involving promo code giveaways will not influence reviews in any way.

Top 10 Hidden Features in Windows 7

Everyone likes to find hidden stuff, whether it�s loose change in the couch cushions or an Easter egg in your favorite video game. Windows 7 has its own hidden treasures. Yes, there are features and goodies to be uncovered�some obvious, some not. And you can access all of those listed here without downloading anything extra (well, mostly). Read on for 10 handy and largely undocumented items in Windows 7 that you probably weren�t aware of...and soon won�t be able to live without.



1. God Mode
It may be hyperbolically named, but Windows 7�s God Mode is indeed omnipresent. It conveniently puts hundreds of settings from all around the operating system all in one place. To turn on God Mode, create a new folder on your desktop, or anywhere you�d like, and name it: GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}. Don�t include the final period. The resulting folder will contain 270 items, representing virtually every configurable option in Windows 7.



2. Enhanced Calculator
Windows� built-in calculator hasn�t really changed much over the years, but Windows 7�s calculator has a few extra tricks up its sleeve, which you�ll find under the View menu. It can do myriad unit conversions (temperature, weight, area), and even mortgage payment or car mileage calculations. It maintains a history of your previous calculations as long as the program is open.



3. WordPad�s File Support
The built-in WordPad word processor in Vista is of limited usefulness because it only supports RTF (Rich Text Format) and plain text (TXT) files. In Windows 7, on the other hand, WordPad isn�t quite as restricted. Although Windows 7�s WordPad still doesn�t work with .doc files from Microsoft Word 2003 and earlier versions, it can open and save ODT (OpenDocument Text) files used by the free OpenOffice.org word processor as well as .docx files created in Microsoft Word 2007 or 2010. Although WordPad can�t understand all the complex formatting (it will warn you of this upon opening or saving a file), it will still let you read the documents without having the native programs installed.



4. Reliability Monitor
When your system is acting flaky and you�re trying to figure out what�s going on, the
Reliability Monitor may help. Search for �reliability� from the Start menu, and run View Reliability History. You�ll get a graph of your system�s �stability index� over a period of days and weeks (rated on a scale of 1 to 10). It displays which programs, Windows components, or miscellaneous items crashed on a given day, helping you identify problem items.



5. Problem Steps Recorder
When you need outside PC help, it�s much better to let them see for themselves what�s happening on your system. But if remote access isn�t an option, the Problem Steps Recorder may be the next best thing. Search for and run psr from the Start menu. Click Start Record, and the utility will record your activities through a series of screen shots, automatically including captions that show exactly where you clicked. You can also use the Add Comment button to highlight specific areas of the screen and insert custom annotations. When you stop recording, everything will be stitched together and saved as a Web browser-compatible MHTML (MIME HTML) file, conveniently pre-ZIPped and ready for e-mailing to your geek of choice.



6. Power Efficiency Report
If your Windows 7 laptop isn�t getting the battery life you expect or it experiences power-related issues, such as the inability to go into standby or hibernate mode, the problem usually lies with incorrectly configured power-management settings. Windows 7�s Power Efficiency Report can help you sniff out potential problems. Type search for CMD from the Start menu, run it as an administrator (right-click cmd.exe on the menu and choose Run as administrator). From the command prompt, type powercfg �ENERGY (include the space) to scan your system, and after about a minute, you�ll find a file called energy-report.html in your \windows\system32 folder. Copy the report to another location and open it (you�ll get a file-not-found error if you try to open it from the system32 folder) for detailed information about what system devices or settings are throwing a monkey wrench into your power management.



7. Pin Folders to the Taskbar
You know you can right-click your favorite programs and pin them to the Windows 7 Taskbar for easy access. There�s no such option for folders, but you can still keep them close at hand on the Taskbar. Rightclick any folder, drag it to an empty space on the Taskbar (or to the Windows Explorer button), and let go when Pin to Windows
Explorer appears. Now when you right-click the Windows Explorer button, your folders will be accessible via the Jump List.



8. Wipe Free Disk Space
It�s no secret that when you delete files or folders in Windows, they�re not actually erased; the space they took up is simply marked as �available for use,� which allows the files to be recoverable until they�re overwritten with new data. There is a utility built into Windows (even XP Pro and vista) that will overwrite all the free space on a hard drive, insuring any files you�ve deleted stay dead. Launch a command prompt and type cipher /w:X (X is the letter of the drive or partition you want to wipe). Be patient; the process can take a long time if you have a lot of free space.



9. �VIRTUAL� WI-FI
If you check out the network connections of most Wi-Fi-equipped Windows 7 systems (except those with Starter edition), you�ll notice an adapter called Microsoft virtual WiFi miniport adapter. This adapter acts as a software-based access point, taking a wired or wireless network connection and making it available via a separate wireless network. This lets you create your own hotspot from whatever network you�re connected to�handy when, say, you want to connect multiple devices to a Wi-Fi network that charges for access. To do this, you�ll need a copy of the free Connectify software.)



10. HOTKEY A WINDOW BETWEEN MONITORS
Want an easy and mouse-free way to move windows around a display or, better yet, between multiple monitors? When you press the Windows key along with the left or right arrow key, the active window will move from its original position and anchor itself to the edge of the screen in the direction of the arrow, and it will do so across every monitor you have. Similarly, if you press the Windows, SHIFT, and the left or right arrow keys at the same time, the active window will jump over to the same position on the adjacent monitor.
