DDoS Attacks: Size doesn’t matter

People often think that Distributed Denial of Service (DDoS) attacks-you know like the ones that knocked the Department of Justice, the Recording Industry Association of America (RIAA), Motion Picture Association of America (MPAA), and Universal Music recently–require hundreds of attackers generating gigabytes of traffic per second to pound a Website down into the ground. Ah, no they don’t.

A DDoS attack can blast a site off the Web with a mere trickle of traffic. As Radware, a global application delivery and application security company for virtual and cloud data centers, just pointed out in its “2011 Radware Global Application & Network Security Report,” smaller, less intensive attack can cause more damage than DDoS attack tools that gobble ten times the amount of bandwidth.

How small? Radware’s Emergency Response Team (ERT) found that the majority of successful DDoS attacks were made with less than 1 Gigabit per second (Gbps).

Five Reasons why Windows 8 will be dead on arrival

Some of my die-hard Windows friends are very excited by Windows 8 arrival later this year. Others fear that Windows 8 will be a repeat of Microsoft’s Vista disaster. Me? I know Windows 8 will be a Vista-sized fiasco.

Before jumping into why I think far more PC users will still be running Windows 7 in 2016 than Windows 8, let me explain that while I prefer Linux as my desktop operating system, I don’t see Windows 8 charge into a brick wall as being a pro-Linux or anti-Microsoft issue.

In fact, as desktop operating systems go, I rather like Windows 7. Yes, really. Besides, it’s not like Windows 8’s forthcoming failure will help desktop Linux. Looking back, when Vista flopped, in the long run it actually hurt desktop Linux. That’s because Vista’s failure, combined with the threat of netbooks, caused Microsoft to revive Windows XP. If Windows 8 goes down the same path, I’m sure Microsoft will extend Windows 7’s lifespan.

So, why is Windows 8 destined to be a non-starter? Simple:

Apple gets kicked in the teeth by German patent lawsuit decisions

I like Apple products. God knows I own and use enough of them. But, I hate their out-sourcing business practices and their world-wide anti-Android lawsuits. So, when I learned this morning that Motorola Mobility had won a permanent injunction against Apple’s iCloud service in Germany because of a patent violation and Motorola had followed that up with another patent victory, which has forced Apple to take all its older phones, 3G and 4 and all iPads off its German online store (German language link), I was pleased.

True, Apple can still sell its current iPhone 4S in Germany, but this is a real kick in the teeth for Apple and its patent attack ways. Apple is putting the best face it can on its defeat. An Apple spokesperson said, “Even if some iPad and iPhone models are currently not available in our online store in Germany, customers should have no problem finding these devices in our stores or from authorized dealers.” Sure. Right. The bottom line is that iCloud’s functionality has been crippled and German Apple customers will have trouble getting their favorite mobile products.

Spark, free-software Linux tablet, to ship in May

Aaron Seigo, one of the KDE’s lead developers, and a leader of the Spark free-software Linux tablet development effort, has reveled more about the Spark, including, alas, that the Spark won’t be available until May 2012.

Seigo explains, “We have a lot of pieces to coordinate, and not just technical issues like the OS image and the content add-on store, but things like packaging design, manufacturing, shipping, import, retail channel coordination. So far we’re on track, but I don’t want to offer a more precise date than ‘May’ until we pull the trigger on production.”

When it does roll down the production line, Seigo says, “the Spark will be available for order online worldwide. We will be focusing primarily on Europe first, but we will be able ship worldwide from day one. We are looking for retail partners elsewhere in the world: USA and Canada, South America, Australia, etc. to make it easier to procure.” Pricing will be around $260 or 200 Euros.

How Web savvy are Romney, Gingrich and Obama?

President Barack Obama recently held a Google+ video Hangout; Republican presidential candidate Newt Gingrich promised to have a permanent U.S. moon-base by 2020; and fellow Republican Mitt Romney, along with Gingrich and Obama, are against the Stop Online Piracy Act (SOPA) and PROTECT-IP Act (PIPA). So, as politicians go, these guys are all pretty tech-savvy right? Well, yes and no. If you look at their Web sites, which is what Strangeloop, a Web site optimization company, did, you’ll find that neither Republicans nor Democrats are as up to speed as you might like.

According to Strangeloop president, Joshua Bixby, “I wanted to see if [their] pro-tech stance extends to Web performance, so I decided to take a shallow dive into their websites and mobile strategies. I was actually kind of surprised to see some interesting patterns emerge.”

First, “Web site speed correlates (mostly) to position in the primaries. At 46.4% and 31.9%, respectively, Mitt Romney and Newt Gingrich led the Florida primary. Interestingly, both also lead when it came to site speed. Gingrich’s site is fastest, with a load time of 7.7 seconds (maybe we shouldn’t be so quick to laugh at his plans to colonize the moon), while Romney’s loaded in 9.3 seconds. Rick Santorum and Ron Paul lagged in both areas, trailing far behind in votes and suffering load times of 10.7 and 13.5 seconds, respectively. (Interesting to note: President Obama’s site fared worst of all, with a load time of 13.6 seconds.)” But, then Obama’s not really running yet either.

Spark: The first free-software, Linux tablet is on its way

Open-source software and Linux, thanks to Android, is well represented on tablets. But, if you didn’t want to deal with proprietary firmware and software, you were out of luck… until now. Aaron Seigo, one of the KDE’s lead developers, and his team are just about ready to roll-out the first tablet based entirely on Linux and free software: The Spark.

For those of you who are a little puzzled right now–”But, isn’t Android based on Linux??” let me start by explaining that yes, Android is Linux and open-source software. But, its implementations on various smartphones and tablets always uses some proprietary software, firmware, and/or shims to combine the code into a working device. Spark is different.

As Seigo explains, “We decided to go with Mer, the community continuation of MeeGo, as our base OSS [open-source software]. With the amazing help of the Mer community, we have been able to bring up a non-Android, built-from-source kernel on the device and even boot into Plasma Active. There is still work left, and we still do have some binary drivers, but this progress is already one massive crowbar that’s prying open the doors that have been shut on the world of ARM based devices.”
