I am increasingly concerned about the fragility of the Internet. With our data living more and more in the cloud, we are vulnerable when networks fail. Without email, without the documents I’m writing or editing, I have to sit out any network blackout that takes place. This happens to me more often than I’d like – probably a couple of times a month in my home office. I’m on Comcast cable for my connectivity, and though I frequently get 10 megabits/second of bandwidth, and almost always have at least 1.5 mbs, there are times when it gets so unreliable it might as well not be there, and then there are times when it just stops working for a couple of hours.

I’m Getting Ahead of Spam. Never thought it possible!
I’m actually finding that I’m getting ahead of my incoming spam load. I get easily 800+ a day at intake end of my inbox. That is reduced by at least 50% by custom rules that I’ve added to my Kerio mailserver. (These rules have to be updated daily with new phrases, but they are quite effective.) And Kerio mailserver has additional behaviors that it uses to reduce spam – together they either bounce or tag most of the incoming spam.
Then another 50% of those that remain are tagged as spam by SpamAssassin (a server-based solution). And finally, each morning I go to webmail and look at incoming messages there, tagging the obvious spam and deleting it, before I have Entourage [Microsoft Office] pull my mail down to the computer. The personal webmail examination step requires 30 minutes of my time every morning, because I’ve gotta look at every title, but while I’m doing it, SpamAssassin is learning how to recognize today’s spammer tricks.
When Entourage picks it up, it uses SpamSieve (a Mac program that uses Bayesian filtering) to additionally filter the mail, and that catches almost everything else. I probably have to delete another 25 by hand from my inbox during the course of the day, and SpamSieve “learns” how to filter those out for tomorrow.
Interestingly, I miss the spam. The number of actual messages that I’m left with in my inbox to really read is maybe 50 a day. I still triage and only answer those that are ultra important right away, and my average turnaround time to respond is probably 24 to 48 hours for everything else. But I’m feeling like this filtering is finally effective for me.
Wireless data in London #TG2009
I’ve been informed that the Traveling Geeks will be provided with British Telecommunications [BT] OpenZone wireless connections while we’re in London in July. From what I read, BT has been building out these services for a couple of years now, and they prominently feature “outdoor” public access to wi-fi. Central London has some number of indoor hotspots and outdoor coverage areas. When I get there I’ll know better how this works in practice.
In the US, several cities have experimented with open or public wi-fi access. [Read more…]
MySQL and Java – two birds with one stone
The old phrase “killing two birds with one stone” – yeah it sounds impossible when you think about it realistically – ka-bing, ka-bing, there they go. But Oracle may succeed in killing off both Java and MySQL after its acquisition of Sun Microsystems. Or at least sidelining both into stagnation in favor of big-ticket licensed Oracle products.
In 1999 to 2001 I was responsible for purchasing Oracle licenses for a large organization with large plans. We paid hundreds of thousands of dollars (US) for initial and continuing licenses on Oracle database software. The stuff was industrial-strength. But since then I’ve used (the free) MySQL dozens of times for small-to-medium size sites. And several systems I’ve used or designed have been Java-based as well. The availability of these free tools is critical to the existence of millions of web sites around the world. [Read more…]
Can short URL sites and Twitter together be attack vectors?
On my site The Social Graph of Malware, I try to present current information (with appropriate background) on malware and attack vectors that use social engineering as a part of their methodology.
Last week I read somewhere (I know not where) about the potential for URL-shortening sites pointing you at sites containing malware. It’s pretty simple – imagine that someone posing as your friend twitters you and there’s one of these shortened URLs inside the message … but that this shortened URL points you at a site containing an embedded virus rather than at a site that you would want to actually visit. Your actual or supposed friend might not even know the site is poisoned. How can you protect yourself against this? Read this page at The Social Graph of Malware for more details. (I promise you there are no shortened URLs in the article.)
