A squareish hand-painted metal sign with the words 'Coffee,' 'Espresso' and 'Wifi' stacked vertically. The letters and border are black on a bright yellow background. The sign hangs from an ornamented wrought-iron-style stand above a planter and is viewed diagonally from above. Between 'Coffee' and 'Espresso' there's a drawing of a cup and saucer with steam rising from it.

When I took this photo back in 2016, it was a combination coffee/Chinese food restaurant: they sold coffee in the mornings and Chinese food for lunch and dinner. The owner had previously run a separate coffee shop (The Bean Counter, IIRC) in the same shopping center, then combined the two businesses to save on rent. It was one of our go-to Chinese takeout sources, and I’d sometimes grab coffee in the mornings if I was in the area or on my way somewhere in that direction.

The old coffee location sat vacant for a few years until a bakery (with coffee on the side) moved in. Amusingly, the bakery — with is still there today — also chose a pun-based name: Redondough (as in Redondo Beach).

In early 2020 — and I mean early, either January or February — they were offered a really nice buyout price by someone who wanted to turn-key convert it overnight to a Hawaiian restaurant. I imagine when mid-March rolled around and the initial Covid lockdown started, they were extremely relieved to have accepted it!

I never did get around to trying the Hawaiian place, even for takeout. Eventually it was taken over by a Hawaiian-style fast food chain.

At a tech training session, I wanted to get access to some of my class-related email on the training computer. But I didn’t want to log into my primary email on an open network, or on someone else’s computer at all. I have no idea what they’re logging, whether they’re doing SSL inspection, whether there’s a keylogger on it — probably not, but who knows?

Heck, I didn’t even want to use my own device on the hotel Wi-Fi without a VPN, and that was at least secured by WPA2! (then again…)

I ended up forwarding the extra class materials to a disposable email account and logging into that one. No risk to other accounts if it got sniffed, at any level.

But I remembered how we all used to get at email when traveling back in the early 2000s, before smartphones, and before every laptop and every Starbucks had Wi-Fi:

Internet Cafes.

We’d walk into a storefront and rent time on one of their computers. Then we’d go to our webmail site and type in our primary email login and password over plain, unsecured HTTP without TLS.

I’d never do that today. Admittedly, I wouldn’t need to in most cases — I can access my email wirelessly from a device I own that I carry in my pocket. (Whether that’s a good thing remains up for debate.)

But more importantly, we know how easy it is for someone to break into that sort of setup. Even if your own devices are clean, someone else’s computer might have malware or keyloggers or a bogus SSL cert authority on their browser to let them intercept HTTPS traffic. An HTTP website is wide open, no matter whose device you use. And an open network is easy to spoof.

So these days it’s defense in depth: If it needs a password, it had better be running on HTTPS. If I don’t trust the network, I use a VPN. And I really don’t want to enter my login info on somebody else’s device.

When I was a kid, motels still advertised “COLOR TV!” on their signs to entice weary drivers to choose their facilities over the next one down the road. I’m pretty sure color TV was standard by then, but the signs remained.

These says, every motel I drive past has “Wi-Fi” on the sign, for the same reason.

Except it’s not quite the same. I mean…can you imagine if color TV was included with every room at the Motel 6, but you had to pay extra for it at a business class or nicer hotel?

That would be kind of silly, wouldn’t it?

You’ve probably seen the story about how a group of teenagers showed that plants won’t grow next to a WiFi router. We did our own experiment, but first some things to consider about the story making the rounds:

  • They tested whether cress seeds would germinate near a wi-fi router.
  • The seeds by the router DID grow, just not as well as the control group.
  • The photos accompanying the news articles I saw don’t match the photos that appear in the report. They actually look like a before and after set.
  • It was done a year ago, in spring 2013.
  • It was a school science project. That’s not a knock, they did some good things like sending traffic through the router to make sure it was actually transmitting, and mixing seeds from multiple packets together to eliminate differences between batches.
  • As with all science, the results need to be repeated in more experiments with rigorous controls to be sure they accounted for all variables.
  • I couldn’t find a followup study in all the blind repostings of the original OMGWIFI claims, though I did find a discussion at JREF. If you can read past the annoyingly dismissive comments, you’ll also find some insightful remarks and links to the actual presentation (in Danish, so it’s tricky to read, but they have charts and photos)…and a few anecdotal stories by people who use the heat from their wireless routers to HELP germinate seeds!

After we read up on this, Katie decided to do a simple experiment herself. She put seeds next to our router, on top of our refrigerator, next to the TV, and for a control, outside. She found that the seeds placed next to our router did just fine — considerably better than those left outside, and slightly better than those placed elsewhere around the house.

Each bag contained one kidney bean, one black-eyed pea, and one seed from the red bell pepper I cut up for dinner. I put a section of select-a-size paper towel, folded twice, in each and set the seeds inside the second fold. Each bag got 15 mL of Brita filtered water and the air was squeezed out before sealing. Then I left them around the apartment for several days to see if they’d sprout. This is a picture of what resulted.

I wonder if the seeds in the school experiment just dried out. Katie sealed her seeds in plastic bags, which allowed radiation to pass through, but trapped moisture. As I understand it, the students watered their seeds throughout the experiment, but it’s possible the trays dried out overnight. Comparing moisture content/retention would be an interesting follow-up.

Obviously, this isn’t any more rigorous than the original experiment. But it shows that the results they found are the beginning of the process, not the last word. More importantly, it’s something you can easily test yourself if you’re so inclined. Next time you see a startling claim that’s something you can test without too much trouble, try checking it out for yourself.

Incidentally: We planted the seeds in our patio yesterday. With any luck, they’ll do as well as our tomatoes (and better than our poor carrots) this year!

Portable cellular phone tower on wheels.As near as I can tell, there were two main wifi networks at the San Diego convention center this year: “Comic-Con 2010” was open and free…and bogged down. It was enough to post snippets of text one line at a time, but it took forever to start the console for Cover it Live, though, and it wasn’t worth it for uploading photos.

AT&T also had a wireless network, but it required you to either be a customer already or buy access. One of the perks of U-Verse service: free access to AT&T wifi hotspots! Since only paid customers were using it, it was a lot faster. Faster even than our home internet access, in fact.

This was in the lobby, hallways and meeting rooms at the convention center itself. I never really tried to access wifi on the exhibit floor (who has room to sit down, other than people staffing a booth?), and didn’t spend much time on my phone either, except for sending and receiving text messages.

Over at the Hilton, however, access was virtually nonexistent: No wifi as near as I could tell, and even phone access was spotty. I saw people texting in the Indigo Ballroom, but the ones nearby were all on iPhones (AT&T) or Verizon. I had absolutely no T-Mobile signal in that hotel, even though it was perfectly fine everywhere else. Katie had the same problem at Indigo last year, and we were hoping it might have improved. No dice.**

One reason I didn’t worry too much about having constant net access: I spent way too much time last year online. Liveblogging aside, this year I wanted to focus more on actually being there. Last year I posted about 30 messages a day to Twitter. This year it was closer to 10 posts total.

So of course, now I’m spending lots of time after we get back writing things up…online.

*Yes, I know the photo is of a cell phone tower, not a wifi hotspot, but I didn’t take any pictures of wifi routers and this is the next best thing.

**Actually, there was a whole booth full of dice, but it was over on the main floor.

I have to confess: I’ve started seriously thinking about a netbook.

Not that I actually need a netbook. I’d only really end up using it for conventions that I’d want to post live (which would probably boil down to Comic-Con International), and I have the ability to do that using either my G1 or the laptop.

Long-time readers (all five of you 🙂 ) may remember that last year I agonized over upgrading my phone to something with real web capability until they announced wifi, and I just lugged the laptop around. Which worked fine, but it was heavy, especially the day I was also carrying around Comic Book Tattoo.

Of course, now I can use the G1 to post to my blog, or Twitter, or Facebook, or (almost) anywhere else even without wifi.

Except…

  • Typing on that tiny keyboard is slow. Not as slow as the onscreen keyboard, but still a lot slower than typing on a full-sized keyboard. Then again, netbook keyboards are also smaller than standard, so it might not be much of an improvement.
  • There’s no easy way to transfer photos from another camera. I can only think of two ways other than using a computer as an intermediary: use a Micro-SD card with adapter in the camera, or get a card reader that will clone data from an SD to a Micro-SD.

The camera issue shouldn’t bother me. Chances are I’d just end up doing what I did for WonderCon this year: post the occasional phone pic to Twitter and then upload the good photos to Flickr each evening. Just like I’d mostly be writing brief posts from the convention and detailed posts at the hotel.

Not my book, but the same page that she signed in mine.But then I remember the post I made on the Tori Amos signing last year. After the signing I was so hyped that I found a table, set up the laptop, banged out a blog post, hooked up the camera and added a couple of photos…and the post ended up getting linked on a major Tori fansite, producing a traffic spike so big that not only is the following day still this blog’s busiest day ever, but that post, even though traffic fell off over time, is the 8th most-viewed post on the site over the past year.

Still, the promise of another 15 minutes of blogfame isn’t enough to justify several hundred bucks. (Though the < $200 models that pop up on Woot from time to time have been tempting.) So I’m making an effort to practice typing with the G1, both the physical and on-screen keyboards. I’ve got Twidroid and I Tweet for posting to two Twitter accounts. I’ve got wpToGo to simplify blogging. I’ve got a plugin that will automatically liveblog using Twitter, which I still need to test.

It’s just a matter of making full use of the tools I have, rather than running after the latest cool toy.

Update: I posted this last night, but somehow it ended up backdated to the day I started it on May 20. I think wpToGo must have set a publishing date when I posted the draft. Yes, I started this post on my phone.
