Gruber on new AT&T data plan

http://daringfireball.net/2010/06/good_and_bad_regarding_att_data_plans

Apropos of the iPad vs. Mifi discussion I’m having with a lot of people. Tethering on the iPhone or iPad could solve a lot of headache, including one’s landline Internet being down. We’re gonna pay for it, but it should be worth it. I’m quite hoping tethering is not a contractual subscription. Month-to-month I can swallow.

Is 5GB of mobile broadband a month enough for most people?

First off:
1024 bytes = 1 KB (kilobyte)
1024 KB = 1 MB (megabyte)
1024 MB = 1 GB (gigabyte)
1024 GB = 1 TB (terabyte)

It’s hard to peg the average size of a web page (so, one person’s profile on Facebook, for example). Easy to say a range between 80 and 300 KB. (This is an interesting page: Average Web Page Size Triples Since 2003.)

Very broad and arbitrary size ranges for other kinds of files:

Photos found on the internet: 100 KB – 2 MB
Higher-resolution images: 2 – 15 MB.
Song files run between 2 – 15 MB.
A half-hour of video, maybe 150 – 175 MB.
A 90-minute movie, 500 MB – 1 GB

So, to the question:

5GB is fine for phones with internet (c.f. articles 1 & 2).

On a computer, however, 5GB may or may not be fine (c.f. article 3 is from a geekier perspective).

I go waaaaaaaaaaaaaaaaaaay past 5 GB a month. I ain’t even going to guess a number. If you only look at static web pages — ones with no videos — and nobody sends you emails with pictures or videos in them, and you don’t download any music or audio-visual material… you likely won’t hit 5GB.

Here’s the important question for your carrier: Is there a way to monitor how much you’ve used up to the current moment in the billing cycle?

1. Beta News: Sprint says 5 GB per month should be enough for most

2. Yahoo! Answers: Is 5GB enough for a normal use on a laptop for broadband access using a USB Card?

3. Buzz Out Loud Lounge: Would 5 GB be enough for you?

Create a wireless network without a wireless router

We have several Mac minis, all connected to our network with Ethernet. We just got a laptop, but we don’t have a wireless router. Can one of the minis create a wireless network?

Yes, that’s super-easy. In Tiger: On one of the minis, go to System Preferences > Sharing > Internet. In Leopard: System Preferences > Sharing, and turn on “Internet Sharing” in the list of services. In there you can share the Ethernet connection via Airport, which tells the mini to create what’s called an “ad-hoc” wireless network. You can name it what you want and password-protect it, too.

Scheduling happens!

Welcome 2009, and welcome to Phase 1 of J2v2!

I’m so very pleased to announce a new appointment-making system up here at J2 HQ. As ofthis Tuesday,Lynn Gosnell has assumed the post of scheduling coordinator. It’s pretty cool that, with some of the amazing web services that have come out in the last couple of years, Lynn — a die-hard Mac fan, as well as writer and editor — can do this from pretty much anywhere — or at least from any internet connection.

Lynn has already made it possible to respond to client inquiries much more quickly than I could by myself. And I have enjoyed putting the mechanisms together to make a complete system. They run something like this:

First of all, GrandCentral (note: see Update below) gives us a permanent phone number (210.787.2709 for your scheduling pleasure). When Lynn wants to take point, she just signs into GrandCentral and points the service at her phone number, and then all calls will go to her. You can even point it at multiple phones, and it will ring in both places simultaneously. We can do custom greetings, custom ringing, spam archiving and blocking… the features are phenomenal.

And guess what? GrandCentral is free! They started out a couple of years ago, got some good press from people like David Pogue, and then the dream of every modern web startup came true: Google bought ’em.

Yet, while phone is a crucial piece of this puzzle, I think we would all agree that voice calls can take time — valuable time — to accomplish decisions that can be made much more efficiently. To that end, email has become the de facto preference for many of us, and text messaging (SMS) works well for others.

What if we could combine email, a collaborative calendar, and shared documents? Enter Google Apps. With 7+ GB storage per user, built-in IMAP support (a requisite for email on the iPhone), and super-easy asset sharing within one’s domain (e.g. j2mac.com) — and, yes, it’s free — Google has built a digital oasis where once was a desert. I have been floored with how well Google Apps has integrated into my business and into the organizations of our many clients who now benefit from this service.

In Google Calendar, the three of us can add to our respective calendars with ease. Lynn can manage mine and Erick’s calendars. We can each keep personal calendars whose event details are hidden from the others, though the “free/busy” information is available. And I can embed our layered calendars onto this siteso clients can see our upcoming availability. I like that someone can send us an appointment request such as “Ted Stevens, retrieve deleted emails, Thursday, 1pm-4pm” and we can copy and paste that into Google Calendar’s Quick Add field. How sweet it is!

We’re starting to use Google Docs to keep a history of our work for each client. We can see these docs on our iPhones, and anyone is welcome to ask us for a link to their J2 document.

Finally, a more new-fangled service called Yammer has enabled the three of us to message the others in a running narrative. Yammer is based on the idea of Twitter; both are geared toward short messages, and rely heavily on text messaging for posting and receiving updates. This is, for me, an important substitute for email, which is too cumbersome for quick updates while on the go. Yammer’s cost? You know it: $0.

Again, this whole on-the-go, location-agnostic way of working was not possible two or three years ago, certainly not with the minimal effort and expenditure we have spent this last week.

Phase 2 is a new look, comin’ your way shortly.

Update: Lynn Gosnell has decided to pursue other projects, so we will have a new scheduling coordinator soon. Also, GrandCentral is no longer subscribing new members.


San Antonio realtors can switch to Mac

I meant to put this out sooner:
The San Antonio Board of Realtors contracted an MLS developer to allow agents and other members to use Firefox and mobile browsers, such as that of the iPhone, to browse real estate listings. This is a huge deal for this market, and potentially for our business.

Current speedtest.net results

Holy Mickey’s Wide Mouth, Batman! I’ve been paying Time-Warner for 12Mbps cable internet, but I just ran metrics a few times at speedtest.net, and here’s what I got:

28,788 kb/s down – 762 kb/s up
17,142 kb/s down – 668 kb/s up
27.723 kb/s down – 659 kb/s up

Those download speeds are ridiculous!

Keep your surfing secure

This is a tiny but important tip: When you go to Gmail or Yahoo! Mail or any other personal web-based service, you can make your connection less hackable by changing the “http://” to “https://“. The “s” stands for “secure,” and it means that traffic — the 0s and 1s — between your browser and the online service will be encrypted.

“Using an https: URL indicates that HTTP is to be used, but with a different default TCP port (443) and an additional encryption/authentication layer between the HTTP and TCP. This system was designed by Netscape Communications Corporation to provide authenticationand encrypted communication and is widely used on theWorld Wide Web for security-sensitive communication such as payment transactions and corporate logons.”
Getting in this habit is especially important for laptop and mobile users. It’s easy to store the https:// in your bookmark. When you use a secure link, you’ll see a little lock icon in one corner of your browser window.
