Does SPF Really Help Curtail Forged Email Headers? 90

Intelopment asks: "My Domain name has recently been used a lot in the 'Reply' field by some inconsiderate spammer, and my ISP has suggested that I consider using the Open SPF service as a way to stop spammers from using my domain name for in their mail headers field. From what I can tell, it requires the receiving mail server to actually participate in the SPF service, which is where I have my doubts. Does anyone have any experience with this service? Does it work? Are many ISPs using Open SFP?"

How Do You Keep Track of Your Web-Based Research? 150

time961 asks: "I use the Web extensively to research a wide variety of topics (weird, huh?). However, much of the time I end up printing out web pages and filing them on paper, because that's the easiest way I know to say 'OK, that was interesting, I'll hold on to it until I actually do something about this topic'. Often, I'll run across something that seems relevant to a long-term project or interest and just want to grab it without even reading the details. Paper is OK for reading, browsing, and scribbling, but it's hard to search, it's heavy, and it's wasteful (and I yearn for a day when browsers can reliably print what's on the screen, instead of cutting it off at the margin because some designer doesn't understand layout!). How do others deal with organizing the results of browsing?"

Is Dedicated Hosting for Critical DTDs Necessary? 140

pcause asks: "Recently there was a glitch, when someone at Netscape took down a page that had an important DTD (for RSS), used by many applications and services. This got me thinking that many or all of the important DTDs that software and commerce depend on are hosted at various commercial entities. Is this a sane way to build an XML based Internet infrastructure? Companies come and go all of the time; this means that the storage and availability of those DTDs is in constant jeopardy. It strikes me that we need an infrastructure akin to the root server structure to hold the key DTDs that are used throughout the industry. What organization would be the likely custodian of such data, and what would be the best way to insure such an infrastructure stays funded?"

Quickly Switching Your Servers to Backups? 73

moogoogaipan writes "After a few days thinking about the quickest way to bring my website back to the internet users, I am still stuck at DNS. From experience, even if I set the TTL for my DNS zone file as low as 5 minutes, there are still DNS servers out there won't update until a few days later (Yeah. I'm looking at you, AOL). Here is my situation. Say that I have my web servers and database servers at a remote backup location, ready to serve. If we get hit by an earthquake at our main location, what can I do in a few hours to get everyone to go to our backup location?"

A Succinct Definition of the Internet? 498

magnamous asks: "Ever since Senator Ted Stevens used the phrase 'series of tubes' to describe his understanding of the Internet, I've noticed several stories and comments referencing how silly that is. Although I agree that that description is rather silly, each time I've found myself trying to come up with a -succinct layman's definition- of what the Internet is, and I come up short. Wikipedia has a gargantuan page describing the Internet, and Google's definitions offer pretty good descriptions of what the Internet is in a functional sense (with some throwing in terms that the layman wouldn't understand, or take the time to understand), but not really a good description of what it -is- in the physical sense that I think Sen. Stevens was trying to get at. What are your suggestions for a succinct layman's definition of the Internet?"

Why Are T1 Lines Still Expensive? 556

badfrog asks: "Over the last 10 years, DSL and cable modem has upped its speed (although in some instances only slightly) and dropped its price. However, the price of a T1 has stayed almost exactly the same. If you had asked me 10 years ago, I would have predicted any geek that wanted to would have fiber or their own T1 line to the house by now. What is with this sad state of affairs that a 'business class' 1.544Mbit connection is hundreds of dollars more than a 6Mbit cable connection? Is it a legitimate case that a high upload rate should increase cost so significantly?"

Why are Websites Still Forcing People to Use IE? 899

DragonTHC asks: "I just visited Movielink's website for research. Their site has a nice message saying, 'Sorry, but in order to enjoy the Movielink service you must use Internet Explorer 5.0 (or higher) or Mozilla/Firefox with an IE Tab Extension (IE installation required).' While allowing the IETab Firefox extension is somewhat progressive, why do companies still force people to use Internet Explorer? Surely the site should work just fine in Firefox? With Firefox's steady gains in market share, you would think that webmasters would get the hint. If you are a webmaster, what are your reasons for forcing IE?"
Education

Should Schools Block Sites Like Wikipedia? 545

Londovir asks: "Recently, our school board made the decision to block Wikipedia from our school district's WAN system. This was a complete block — there aren't even provisions in place for teachers or administrators to input a password to bypass the restriction. The reason given was that Wikipedia (being user created and edited) did not represent a credible or reliable source of information for schools. Should we block sites such as Wikipedia because students may be exposed to misinformation, or should we encourage sites such as Wikipedia as an outlet for students to investigate and determine the validity of the information?"

What's Your Site Rotation? 109

joeljkp asks: "Nearly everyone has a news rotation — that list of sites you visit each day to catch up on the latest in whatever you're into, be it foreign affairs or knitting. I usually do the rounds at BBC News, The New York Times, and a couple local papers. What have you found that keeps you informed and entertained every day?"

Decent Co-Location or Virtual Server Hosting? 145

gclef writes "Speakeasy announced recently that they're being bought by Best Buy. Despite all the promises to the contrary, I suspect my ability to host servers in my home is going away soon. Does anyone have hints as to where I can get a reasonable co-lo space or virtual hosting? I don't want to outsource the management of my domains entirely, nor will 'webhosting' be good enough, since I like having control of my own stuff (and like running my own DNS, IMAPS, and other assorted network services). Is there some place that will give me a blank box with an unfiltered connection to the net?"

Online Higher Education in Second Life? 67

XxtraLarGe asks: "As both a technician for my college's Distance Learning program and as an avid gamer, I have been tasked with investigating Second Life as a possible way for us to extend and enhance our online classes. I've done a lot of research, reading about what other schools have done. While I personally think it is a really cool idea, I am somewhat skeptical of the actual practicality and value of what seems to be a glorified chat room. I'd like to hear from others about their education experience in Second Life, particularly if you've been involved in setting up any online classes or taken any online classes. What sort of training would be required for the faculty, and is it really worth it?"

How Do You Re-Sell a Domain Name? 64

dclayman wonders: " I've never sold a domain before. I just received a $400 offer for a domain I own (radicaltrust), but I don't know if I should sell it or auction it off. If I auction it, what site should I use? I could really use the extra cash, and I was hoping to get some ideas and advice from other readers. So, what's the best way to go about selling a domain?" Of course, selling your domain is only half of the issue. What's the best way to go about smoothly transferring the domain, once it is sold?

Accurate Browser Statistics? 137

zyl0x asks: "A co-worker of mine has been made responsible for a large web application for our software product, and he was having a hard time deciding what functionality to implement, and whether or not to sacrifice functionality for a larger user base. With Walmart's harsh stand on browser compatibility, we got to thinking, exactly how many users would we be alienating by using some IE-only functionality on our website? We tried crawling the internet to get some current, accurate browser usage statistics, but we could only find stats for specific websites. I thought I'd try sending Google a request, since we imagine they'd have the lowest-common-denominator in terms of types of users, but I received an email from their press department telling me that they 'don't make that kind of information available.' Where can one get a current, accurate, and un-biased measurement of browser usage? Is it even possible?"

Alternative Registrars to GoDaddy? 218

Futurepower(R) wrote in to ask for your suggestions about reliable domain name registrars. With GoDaddy, the one-time favorite registrar, suspending domains based on the wishes of the Irish High Court, and 'requests' from MySpace, is it any wonder that people are starting to lose faith in it? A word of warning from the last article linked in the last sentence: "(GoDaddy) reserves the right to terminate your access to the services at any time, without notice, for any reason whatsoever." Chilling words from a domain name registrar. So what registrars would you recommend for people looking to replace GoDaddy, and how would you suggest they go about transferring their domains in a hassle-free manner?
