Ruckus ICX 7150-C12P Switch (Brocade)

After the recent death of one of my long-running Juniper EX-2200Cs, I needed to find a replacement. I decided to go with a Ruckus ICX 7150-C12P-2X10GR, which is a 12-port PoE switch with 2 10G SPF+ uplinks. It's basically a rebranded Brocade switch. I'd been happy with the Juniper, right …

SmartUPS not equal BackUPS

This is one of those "should have figured that out myself" problems, but I figure I will warn anyone who might be in my shoes.... Check the specifications carefully before investing in an APC UPS. Not that I'm going to suggest going with another manufacturer, just that I'm going to …


VPN from MacBook Pro

I've been using a MacMini running OSX Server to do VPN at my house for about a year now. It worked very well until I got my new MacBook Pro. Unfortunately, there have been problems since then. I now have a call into Apple and a nice work-around. I'm not …

Ars' take on the Apple Intel switch

An article from Ars Technica attempts to put a different view on why Apple announced their switch from IBM's PowerPC chip to the Intel brand processors. Whereas the article had some interesting, and probably correct assertions and ideas, I do think that there are some points that are either glossed …

Rampant speculation over PPC->Intel switch at Apple

CNet is again reporting that they have heard strong rumblings that Apple will announce on Monday a switch to Intel-based CPUs in the Macintosh line. I'm skeptical, but we were all skeptical when people discussed the switch to the PowerPC from the 68xxx architecture in the early 1990's, so we'll …

DSL vs. Cable war heats up over limits

The big claim of cable internet access over services such as DSL is the faster download speed (DSL is often limited to between 512kbps and 1mbps, whereas many cable providers have 1.5-3.0mbps maximums). Security Focus is carrying an Associated Press article that discusses recent moves by Comcast to …

Will cable be forced to compete?

An article from the Washington Post discusses some of the possible implications of a opinion by the US Court of Appeals for the Ninth Circuit which vacates an FCC ruling that cable modem internet services are an "information service" as opposed to a "telecommunications service" and thus are not subject …

Network Solutions and Internet Privacy?

Karl Auerbach (all-around good guy, former ICANN at-large member, California lawyer) points out in his latest weblog entry that Network Solutions (purveyors of SiteFinder, that place everyone now goes when they type in the wrong domain name) has started a new web site aimed at domain information privacy called InternetPrivacyAdvocate …

RIAA sues wrong person

In what appears not to be the only case of its kind, the RIAA has withdrawn a suit against a Macintosh user who they claimed was using the Kazaa file sharing service to share 2,000 songs. The problem? Kazaa doesn't run on the Mac. According to an article in …

Capacity caps on high-speed internet use expand

An article from CNet this morning describes the experience of one Comcast cable internet user who recently received notification from his service provider that he was causing an "unreasonable burden" on the service and that if he did not cut his usage in half, his service would be suspended. This …

OSX no longer immune to net attack

Although we have yet to see an OS X worm appear in the wild, and the operating system itself is pretty well guarded by virtue of it not having many network services turned on by default, the risk to Macintosh users has just gone up. Making the rounds recently is …


FBI internet wiretap proposal doesn't make sense

I read with growing concern an article from CNet about a proposal by the FBI to create a system that would facilitate eavesdropping on telephone conversations made over VoIP networks. The request seems innocuous enough, they already have the right to tap your phone, the internet is being used to …

Iraqi's taste internet freedom with a little indigestion

An article from Wired this week describes the recent adoption of instant messaging by people in areas of Iraq fortunate enough to have power and Internet service. However, the addition of broadband features such as voice chat are bringing cheap communications, and bandwidth problems, to the country. The basis of …

RIAA's reign of terror spreads

It's not aimed at stopping you from traveling, or keeping you from getting an abortion, but the legal tactics being employed by the RIAA (as described in an article from the Associated Press) certainly seem to qualify as using fear to coerce behavioral change, thanks to our duly elected representatives …

PCWorld looks at cheap ISPs

Are you paying too much for your dial-up ISP service? Once you read this article from PCWorld, you may think so. The article surveys some very basic ISPs that run in price from $4.50 per month (that's right, dial-up internet access for ~$50/year) to $22 per month (EarthLink …

More Opteron bus information

Following up on a discussion earlier this week, I wanted to lay out some additional performance comparisons between the IBM PowerPC 970 and the AMD Opteron. Thanks to Dmitry for the pointer to this AnandTech article about the Opteron architecture. Opteron memory philosophyThe design of the Opteron memory and …

How did Apple get coverage with just a few antennas?

Those at the Apple World Wide Developer's Conference last week had mixed reviews for the wireless access. Although coverage in the facility was excellent as far as signal goes, there were troubles with the volume of users on the system. Most of the problems were because of the sheer numbers …

Speakeasy encourages WiFi sharing of DSL connections

In a new twist, speakeasy, a high-speed internet provider has branched out into helping its customers provide WiFi-shared internet connections. As far as I know, this is the first company to offer a service to provide the billing and back-end support (email, etc) for customers who are sharing internet via …
