Equipping your network with a web server can provide some useful extra ways to share files and information. Of course if you’ve tried to set one up before then you’ll know the process isn’t always straightforward, but Serva aims to change all that.

The program offers straightforward support for several protocols (http, ftp, tftp, dhcp, dns, sntp, syslog), yet somehow remains ultra-lightweight (under 2MB). And better still, it’s portable, which means you can run servers just when you need them, without affecting the host system for the rest of the time.

About a week ago I finally moved the cringely.com domain to EasyDNS from Network Solutions, my registrar since 1992. I have written in the past about how much I hate Network Solutions, but this was our final connection and I am now free. But not without them kicking me on my way out the door, crashing this blog for four hours over the weekend.

I began the domain transfer last Monday but Network Solutions, in its infinite wisdom, decided to complete the transfer on June 24, Sunday, at 2:04 pm Pacific time. That’s when they simply shut down my DNS despite the fact that I’m still paying for their service (I’m paid up until November). According to EasyDNS, of all the domain registrars only Network Solutions and GoDaddy drop customers cold like that.

When carrying out research online you may often find important pages that you’d like to save, and of course you might do this by simply clicking File > Save from your browser. The results can be a little messy, though, with files and folders scattered everywhere, and reviewing the pages later might be difficult.

Local Website Archive tries to help by storing the pages for you. There’s no need to worry about file names or folders -- the program can handle all of that -- and when you’re done you’ll have a neatly presented archive of pages, which is far easier to browse and search.

Our brains are incapable of multitasking.

That's the claim of the folks at OnlineUniversities.com, which sent me nifty infographic "Digital Stress and Your Brain". There is a lot of interesting data, but two sentences caught my attention: "Our brains' attention levels are finite. When our brain is overloaded with information, it can trigger a 'fight or flight' reaction. The overload makes the brain feel threatened, so it shuts down higher brain functions that deal with empathy".

Two days ago, 3,000 important websites, including Google, Facebook, YouTube, and Yahoo as well as many top Internet Service Providers, turned on their IPv6 support and this time they left it turned on. Nothing happened. Or maybe I should say nothing bad happened, which is good, very good.

The world is quickly running out of new IPv4 addresses, with almost 3.7 billion issued. There are two workarounds: 1) complicate the Net further with cascading arrays of Network Address Translation (NAT) servers that slow things down, inhibit native inbound connections like VoIP, and defeat location services both good and bad, or; 2) move to IPv6 with 128-bit addresses (IPv4 is 32-bit) that would allow giving an IPv6 address not only to every person and device but to every sock in everyone’s sock drawer as well, allowing bidirectional communication with hundreds of billions of devices from pacemakers to doorbells. Editor: Yes, but what about the socks that disappear in clothes dryers?

Comcast said Thursday it plans to make changes to its pricing structure to start billing for the amount of data customers use, versus the capped method in place today. The cable company will test two different pricing structures in some markets, while hard enforcement of the 250GB cap put into place in 2008 would end.

Both piloted pricing structures give users 300GB of data at a flat rate. Where they differ is in how this allotment is treated: one solution places this cap across all of Comcast's tiers, while the other carries the 300GB allotment for the Internet Essentials, Economy, and Performance tier and higher allotments for faster tiers above that.

When browsing the Internet you may well have noticed that some of sites you visit are secure, while others are not. While HTTPS is most often used for secure shopping and banking web sites, there is no reason that connections to other pages should not be encrypted to help improve privacy and security. If this is something that has concerned you, HTTPS Everywhere could be just what you have been looking for.

This free browser extension can be used to ensure that a secure connection is used whenever available. There are a huge number of websites that offer support for encrypted HTTPS connections, and yet will default to sending visitors to the regular, unencrypted HTTP version of the sites. HTTPS Everywhere uses a series of specially written rules to redirect your browser, provided you are using Chrome or Firefox, to the secure version.

When you need to know more about a web domain, then your first instinct will probably be to visit your favorite WHOIS site. But while that’s quick and easy, there could be an even more convenient solution in NirSoft’s DomainHostingView.

As ever with NirSoft tools, the program is portable and extremely small (just 219KB including documentation), and it’s very straightforward to use: just type the name in question in the Domain box, click Go, then wait as DomainHostingView uses a variety of DNS and WHOIS queries to assemble the data you need.

What timing. I posted my iPad for sale on Craigslist over the weekend -- and two people are jockeying to get ahead of the other to buy it today. But I'm suddenly unsure about selling, after seeing a Macquarie Capital report claiming that Chrome will come to iOS as early as this quarter. Hot damn!

I rarely make decisions based on rumors, nor should you. Besides, the "timing is unclear, but it could be as soon as Q2 and is very likely to be a 2012 event", according to Macquarie Capital. "Could" be this quarter and "likely" this year stink of pure speculation -- or big back door should there be no Chrome for iOS this year. In the end, I'll likely sell the iPad, but must convey this: Chrome would be a very good reason to buy an iOS device but be akin to Google cutting off one limb to save another.

Cash as a form of payment is rare these days as plastic takes over, and online it is all but nonexistent. Not anymore, though -- Walmart now allows online customers to pay for their orders with the good ol' Greenback.

Here's how it works: customers place their orders on the website, and select "Cash" as the payment option. They then have 48 hours to take a printed-out copy of the order form and pay at any local Walmart store. Walmart's demographics seem to support such an offering, so it is obvious why the retailer would offer cash as a form of payment.

Indeed, these are the kinds of problems we would love to have, but when they actually occur we need solutions nonetheless. So, how do you handle the issues that occur when audience demand overwhelms the infrastructure you have provisioned to serve your content?

A few years ago, my company was approached by Latin Interactive Network (LIN), a publisher of online games across Latin America, including countries like Peru, Argentina, Chile, Colombia, and Mexico. LIN handles several successful MMOs in these territories, including the Spanish-language version of Audition Online, a unique free-to-play dance battle game. Audition is a big favorite, and in Latin America alone, the game is now played by half a million players per month. This is welcome news for LIN, of course, but not always so welcome for Audition gamers who may be stuck using outdated and underpowered infrastructure...

Do you find that you never have time to read the articles you discover online? In the past you may have turned to Read It Later to bookmark a site so that you can refer back to it later, but now there is a new analogy to work with. Read It Later has been re-launched as Pocket, so you can now ‘pocket’ those stories you don’t have time to read right now and save them to your online account ready for when you have more spare time.

The rebranding is more than just a change of name; there are also new features that you can take advantage of as well as a redesigned interface. Whether you are surfing the web in your preferred browser, or you discover an interesting link on Twitter or Facebook, Pocket enables you to quickly and effectively bookmark pages, images and videos so you can easily access them later. Content can be saved using a browser extension or using the dedicated iOS or Android apps.

Surely it's no surprise that nearly nine out of 10 American adults owns a cell phone. But would you believe that 19 percent own an ebook reader or tablet? Or that one in five dosen't use the Internet? These are among the fascinating findings from a fresh Pew Internet report "Digital Differences".

The findings are a blueprint for understanding Americans' digital lifestyles and what gadgets -- and supporting products and services -- fit in where. Major tech companies create distinct digital lifestyles people buy into, which is particularly true for Apple, Dell, Google, Microsoft, Samsung and Sony among others. Apple, Google and Microsoft are in pitched lifestyle product competition, and should look to studies like this one to understand the stunning nuances connected, so-called post-PC devices bring to consumer behavior.

There are no snow days on the Internet. If you work from home and write online like I do, drudgery never ends. Or does it? This Saturday, Anonymous may change that.

"To protest SOPA, Wallstreet, our irresponsible leaders and the beloved bankers who are starving the world for their own selfish needs out of sheer sadistic fun, on March 31, Anonymous will shut the Internet down", so claims a February 19 Pastebin post.

When NetZero burst onto the scene with the promise of free Internet for all in 1998, it was a transformative moment. No longer was the Internet a playground for the privileged: all you needed was a computer and a phone line, and you were online. The company is about to do the same for mobile data.

Starting today, NetZero is offering 200 megabytes of data free to anyone who purchases a dongle or hotspot from them. The dongle retails for $49.95, while the hotspot sells for $99.95. The service is provided through a partnership with Clear. With the purchase, NetZero's free plan will remain in effect for a period of one year.
