237 Mile WiFi Range (802.11) with Linksys WRT54G Routers

Did you know there’s a 237 mile point-to-point WiFi link in Venezuela that achieves 3 Mbps throughput? They used Linksys WRT54G wireless routers, one on each end. Both are running Linux-based firmware.

Can you detect an ATM skimmer?

If you’re thinking of ATM skimming as clunky hardware that’s easy to detect, think again. Taped on hardware and bulky card swipe gadgets are a thing of the past. Good thieves use expensive equipment that works and they don’t get caught. They’re like ninja’s in that no one really knows if they exist.

Toshiba ultraslim Android laptop using ARM

ARM is greater than Intel for power consumption vs performance. ARM processors will win the tablet/laptop war in the long run. There, I said it. Unless they make some serious pitfalls, ARM should have a serious stranglehold on the future of tablet PC’s and other mobile devices.

Ethernet cables to replace HDMI for audio/video

The price finally comes down to a somewhat reasonable level for HDMI cables and now they don’t want to sell them anymore. What about small devices that incorporate hdmi such as phones?

Custom udev rules and external program debugging

In udev rules, the %k, %b, %n variables are nice and all, but you can also use the variables you’re comparing and setting such as ID_FS_TYPE, KERNEL, SUBSYSTEM, PHYSDEVPATH, etc. When you run a command in a udev rule, there’s nothing stopping you from calling a shell and executing a few commands without actually calling a standalone script to do the dirty work. If you write out the array of environment variables from inside an external program, you can get a better understanding of just which part of the device discovery is matching your rule and getting processed.

Configuring Linux services on embedded devices is always a pain

I hate configuring things like GPS devices that run super restricted verisons of linux or some other OS. They never seem to deal with error handling very well. For example, here’s the oddball command for fetching ntp.conf and ntp.keys from a ntp server onto a Symmetricom GPS receiver. This is what you want to see, it just works. But in the many failures leading up to this configuration, it was finding problems fetching the files or having the correct access but it was happily coasting right along, overwriting its own configuration with jibberish and rebooting it self only to find the configuration was bollocks.

ATI eyefinity is limited but I still want

ATI eyefinity video cards support up to six displays and multiple cards can be used together in a single machine for a single virtual display. AMD says they’ll be able to chain together enough of their eyefinity cards to create a resolution that approaches eye-definition optical clarity at 12x 1080p.

Self-track Your Life: Change Your Future

Self tracking, or “personal informatics”, is a growing trend of keeping a log of data surrounding the events in your life, and the avenues are expansive. From monitoring weight, heart rate, and blood pressure, to geo-tracking using GPS receivers, to genome profiling and Internet meetup groups, there are a wide variety of people and interests involved in this new fad. I have a hard enough time tracking my fitness routine at the gym, so anything that takes the manual labor out of tracking my statistics is a plus to me.

Emotiv Headgear and the Future of Avatars

Maybe i’m one of those minorities, but just last year’s Surrogates movie showed the darker side of avatars. Think of the expectations you face when avatars integrate into your working life. Avatars interacting between two coworkers is one thing, but between the HR department or other organizations is another. Now I’ll have to worry about being mistreated or discriminated against if I don’t choose the proper look.

Google Nexus One Smartphone has arrived

The Nexus One was released today! Built by HTC, the unlocked version is $530 (the phone works with “nearly all” GSM SIM cards, according to Google) or you can pay $180 for the typical two-year contract with T-Mobile. if you already have tmob service, but don’t have a data plan, it will cost $280 for the phone. Google says there will be other carriers and plans coming sometime in the future. I think the arrival of the Google phone pretty much spells the end for the Droid.
