caa records

If you bother to read this, CAA Mandated by CA/Browser Forum you’ll learn that CAA (Certificate Authority Authorization) standard designed to prevent bad actors from creating unauthorized SSL/TLS certificates has been implemented as of September 2017. CAA records allow domain owners to specify which Certificate Authorities (CAs) are permitted to issue certificates. This is acheived by adding CAA information to your domain’s records at the host level.

Good news. My host added this functionality, and it’s a simple process to now identity who can issue an SSL certificate to your domain. In my case, it’s Now my SSL rating has gone up. Legit.



sopa pipa and megadownload

Does anyone noticed the unbelievable coincidence of the Megadownload take down, just one day after the incredibly successful "internet blackout" protest of Wed Jan 18th?

Update: Glad to see that Kim Dotcom got out on bail, and was able to get his assets unfrozen so he can mount a proper defense. My take is simple. We're talking copyright infringement, not international terrorism, rape or murder. Or bank fraud that brought down the US economy.

If it were not for the unduly powerful influence of the entertainment industry, penalties for copyright infringement would be compensatory to the crime; if you stole a candy bar, who would fine you $100,000 or send you to prison? A movie costs a few dollars to rent. Just ridiculous.


This thing's getting RMA'd:

And Chumby must have had their Xmas party…

chumby one

What's a chumby? A funny-named device that's a cross between a clock radio and data-enabled cellphone? Chumby Industries says, "Just plug in your chumby, connect to your network, and use your computer to create a lineup of favorites from over 1,500 apps in more than 30 categories. Then let your chumby do its thing — streaming everything you like, from sports scores to stock quotes, from video clips to interactive games, from photos to trivia." So yeah, it's a computer-ish device that's connected to the internet. I want one!

A coupon code (HOLIDAY10) from their Facebook page and $90 later, the chumby one (actually their second model) arrived at my door. Very much the size of a small clock-radio, it sports a 3.5" color touch-screen interface, a large volume knob on its side, 5V AC adpater (it does run on battery, not included), and an amazing 2W mono speaker. After flashing it with the latest firmware (1-0-7) via USB, I was able to connect to my home wifi network. From there, I used my computer to create an account at and activate my chumby (now called "chumbly"). Next, again through their website, I set off to configure a "channel" with various "apps" by deleting most everything from the default channel, and adding a flip-style clock, the Weather Channel, Spongebob, XKCD, you get the drift…

When on, the chumby continuously cycles through the various apps on a channel; each time the app refreshes itself with new information from the net. Whether rss feeds, stock quotes, word of the day, Facebook news feed, Flickr albums, Gmail, Twitter, you name it, there's probably an app available. And if you can't find what you want, write your own; each app is basically an Adobe Flash animation. The chumby also plays music very well, from terrestrial FM radio (well, not so well in my case), to Pandora, Shoutcast – why it even connects to my Squeezbox server as player "Neptune"; the only rub is I need to compile its playlist from a computer. And because the chumby is basically a linux computer running an ARM processor, you can do all sorts of geeky things with it too! BTW, it has a fantastic "night" mode that dims the screen perfectly.

Okay, it's a gizmo, it's slightly gratuitous, and really should be offered in other colors. The app selection is superfluous, but it's rather strange that there isn't a "children's" category, because my kids love this thing! The chumby is certainly extensible, but a lot of its value depends on intended use. In the bedroom, it's little more than a clock radio – do I really need to wakeup to Facebook or Engadget news feeds? No, though that might be useful in a kitchen setting, somewhere a computer isn't. It is however the best clock radio I ever bought, one that even connects to my Squeezebox server. What fun the chumby is!

first impressions of the nokia 770

Not sure how I missed the introduction of this product, but upon learning of its debian-based os I couldn't resist. It's more than a pda and less than a laptop. It's beautiful display supports WVGA (800×480), while its linux core allows all sorts of things an itjerk would love. Couple that with a price of $350, I was off to buy the Nokia 770 "Internet Tablet". As I live in Chicago, I was also fortunate to purchase it from America's first Nokia store, where I could give it a test drive, just to lay aside any lingering doubts. The Associates most certainly weren't geeks; no one even knew what "terminal" or "ssh" meant, but they did offer to flash the OS to IT2006 (Maemo 2.0). Of course, I wanted to do that! But it passed all tests (including WAF), and I was one satisfied customer.

To call the device bleeding edge would be an understatement. Physically, the internet tablet is an odd size, and after holding it for about a half hour my hands were tingling. The hard case is awkward to handle, and when you slide it under the bottom of the unit, it's hard to get the stylus out or plug headphones in. I still have no idea what the buttons on the left side of the unit are for, and have no clue whatsoever on how to cut and paste text. The single worst aspect of the 770 is the handwriting recognition. Why couldn't it be the same as Palm OS? That works like a charm. But if all I wanted to do was complain about the 770s shortcomings, whats the point of buying it in the first place? It's the ulitmate 2006 geek toy!

The unit shipped with Internet Tablet 2005 Edition. From all accounts, the upgrade to 2006, released just this month, was a must. On my Windows PC, I had to download an update to MS .Net framework first before I could flash the device. It's a simple process, even for the most technically incompetent. Later I read that there are Mac and Linux based flashers available from The appeal here is that the device can be r&d mode enabled (which gives your root access), and you don't have to have Windows.

I got the mac address for the unit from a sticker on the soft case, configured my wireless firewall, and in no time was using it as Nokia intended – surfing the web with the Opera Browser. But that didn't last for long…
