How CDNs and Alternative DNS Services Combine For Higher Latency 187

Posted by Soulskill on Saturday May 29, 2010 @10:41AM from the taking-the-bad-with-the-good dept.

The_PHP_Jedi writes "Alternative DNS services, such as OpenDNS and Google Public DNS, are used to bypass the sluggishness often associated with local ISP DNS servers. However, as more websites, particularly smaller ones, use content distribution networks via embedded ads, widgets, and other assets, the effectiveness of non-ISP DNS servers may be undermined. Why? Because CDNs rely on the location of a user's DNS server to determine the closest server with the hosted content. Sajal Kayan published a series of test results which demonstrates the difference, and also provided the Python script used so you can test which is the most effective DNS service for your own Internet connection."

The RIAA's Rocky Road Ahead 542

Posted by kdawson on Tuesday December 23, 2008 @05:47AM from the bring-checkbook dept.

The RIAA's new plan to enlist ISPs in its war on file sharing, once it announced it was calling a halt to new consumer lawsuits, is running into rough sledding. Wired reports on the continuing legal murkiness of the RIAA's interpretation of copyright law. And one small ISP in Louisiana asks the recording organization, "You want me to police your intellectual property? What's your billing address?"

Your children are at risk! While browsing online, they may be exposed to many forms of humor, including parody, sarcasm, and even irony. Most parents are unaware of the dangers these pose. Symptoms of exposure include:

Sassing and Talkback
Uncontroled Laughing
Creative Impulses
Original Thoughts

Your child could be reading The Onion at this very moment...exposing thier tiny, unformed brain to a world of raw, hardcore comedy. Take action now! Before it's too late!

I've been using Skype for about a year now and have been waiting for this feature just as long.

I just downloaded 1.0, bought 10 EUR of credits costing 11.5 EUR including Swedish VAT.

Being midnight in Sweden, I had no one to call so I asked my girlfriend to go into another room to test it with my own phone. The sound quality was very good.

Actually, the first call I made was to my girlfriend (in the same room as the computer) 5 minutes earlier before I told her about it. I turned down the computer sound so she couldn't hear that I was calling. When she answered I turned up the sound so she could hear her own voice echoing from the computer speakers. She got really scared and hung up before realizing what actually happened.

Journal Journal: Oregon Coast and OryCon

Journal by Jack William Bell on Wednesday November 12, 2003 @01:20PM

Anita and I will be travelling for the next few days. First down to visit my parents on the Oregon coast, then back up to Portland for OryCon over the weekend. I will try to get the rest of the 'best of' posts up when I can. (I have posted tons more verbage than seems reasonable in the last year, so there is lots to go through.)

Eric Raymond's blog 'Armed and Dangerous' has moved here. Which may be a good thing, he is certainly posting more. His latest rant tears a new asshole out of the ". . . dope-smoking ponytailed dimwits . . ." who create stylesheets with absolute font and box sizes. (AKA graphic designers...)

Well I know what RSS is of course, but you might not. And I could tell you, except Mark Pilgrim does a better job of answering the question 'What is RSS?' than I could. So you should read that.

(It seems odd to call this post 'Best of: The Columbia Disaster' when there was nothing 'best' about the Columbia disaster. However this is the first part of a series of entries linking to my best posts in the past year, and these posts certainly qualify.)

Journal Journal: Did NASA Nuke Jupiter? 6

Journal by Jack William Bell on Monday November 10, 2003 @11:53PM

According to Richard C. Hoagland NASA may have accidently set off a nuclear explosion on Jupiter when they sent the Galileo probe plummeting into its depths.

A fascinating idea, and the background information is very interesting on its own. However Hoagland's tendancy towards conspiracy theories makes him an unreliable source. In so many ways...

Journal by Jack William Bell on Monday November 10, 2003 @06:01PM

One year ago today I posted my first /. journal entry. From the beginning I have used this /. journal as more of a weblog than a personal diary. Although I have sometimes talked about my personal life, and occasionally posted a rant or an essay or a review, most often I just posted links to something I found interesting at the moment and wanted to be able to find again in the future. So,

I am driving one handed while I fumble for my cell phone. Quick glance, select the number, press 'Call'. Put phone to my ear. It rings.

"Hello?"

"Anita, it's me. I am driving down Pine and guess what I just saw in the sky?"

"What? Oh, the Concorde. Very cool! It was supposed to come in at 3:00."

"Ya, I think it was on final approach to Boeing Field."

"Well, now you have something to blog."

Journal by Jack William Bell on Wednesday November 05, 2003 @05:51PM

Nelson Minar thinks so. According to him Python has reached the point that you can create the same kind of quick and dirty Windows applications VB is best suited for. He has pointers to lots of good Windows Python tools.

Journal Journal: Not all that is Sterling is precious 2

Journal by Jack William Bell on Wednesday November 05, 2003 @01:11PM

Some time ago SF writer Bruce Sterling gave up his blog on my friend Eileen Gunn's webzine Infinite Matrix in order to start a new blog for Wired magazine. This trend towards subsidized blogs is an interesting one and I hope it brings enough value to continue (and perhaps be extended to 'regular' bloggers like myself).
