Random Questions and Thoughts. Password Protected Garage Door Remotes, Twitter Security, MUNI Drivers, Burgers, etc

Artem Russakovskii — Wed, 04 Mar 2009 13:00:00 +0000

From time to time my, still curious, mind accumulates a variety of questions and concerns which it has to spill onto the pages of this blog. How random are these? Pretty damn random, and I need to see some answers, quick. Oh, and I’m deliberately not searching Google, as I want to facilitate discussion. What fun would it be if I just looked up all these?

Password Protected Garage Door Remotes

As a paranoid person and a recent homeowner, I started to wonder how safe I actually am in my house. Consider this likely scenario that nobody seems to be concerned with:

I park my car outside for one night and don’t take out my portable garage door remote, the one with a single open/close button. Or, even worse, the remote code is programmed into one of those garage opener buttons built into the car. A car burglar comes along, breaks the window, and trashes my car. Wow, an added bonus – a free entrance into the house!

Needless to say, this is bad already. How many of you lock the door between the house and the garage? What if you forget to do that as well? Is there a spare house key laying around in the garage? You may say “but I’ll hear the garage door open” but does it actually make you feel better? You will be present with an intruder in your house, which will scare the living shit out of you non-governator types.

So here’s my question to you, Internet, is there a garage door remote I can buy that has a programmable keypad, so that a password is needed for the button to work? In fact, it would be almost the same as the one that mounts next to the garage door. And can it not cost $100?

Twitter Security

This part is not about computer security, as you may have thought at first, although I did recently discuss it in the Clickjacking article. I also know that I’m not the first one to bring this issue up but I think it’s worth discussing some more. Consider this scenario:

You’re a cheerful, outgoing snowboarding enthusiast with 3000 twitter (plurk, facebook, or another social network but twitter is the most relevant example) followers. Or maybe you have 3 followers. There’s a 99.9% chance that your profile and updates are public (if you have 3000 followers with a private profile, you must be some sort of a chump. And yes, I did just make the stats up, want fight about it?).
So, on Friday night, you send the following tweet: “Gone snowboarding for the whole weekend. But not before getting piss trashed Friday night at the casino. Wooooo”.

Since anybody can watch your tweets absolutely anonymously and it’s extremely easy to dig up an address knowing very little about a person, what you just said was “If you are a burglar looking for the next opportunity, just drop everything and come on by Friday night. I will be far-far away but my house (located at 123 Main St) will be available for your robbing pleasures. You only have 2 days before anyone is home, so feel free to crash on the couch and eat my food. Don’t forget to feed the cat. Kthx.”

Is this a likely scenario? Not really, unless twitter raises the tweet length to more than 140 characters, but otherwise you see where I’m going with this. Don’t be stupid – avoid advertising exact details of your whereabouts, vacation plans, etc. There are plenty of uses for Twitter without giving up most of your privacy. Ask yourself: would you post a note with your whereabouts on your door every time you leave the house for a while?

How Do Trains And Buses Know Where They Are?

If you live in a relatively large city, you have seen relatively accurate bus and train arrival predictions and, in some cases, almost exact locations of each vehicle. For example, here in San Francisco we have MUNI stations with live maps of trains’ whereabouts and bus stops with bus predictions on small electronic displays.

What is the technology behind it? It cannot be just GPS, because trains go underground where there is no reception. If it’s a combination of externally mounted sensors, are they also placed outside, once the train gets out into the street? Or is it some sort of a 2-way GPS (a conventional GPS device is just a receiver) underground that switches to sensors above ground? I don’t know but I want to.

Train/Bus Drivers And Bathrooms

While I’m on the public transportation subject, here’s what I want to know: if you are a train/bus/trolleybus driver, what do you do if you NEED to go somewhere when you are half way down your route? All of us had such moments at least once, and sometimes you just HAVE TO drop the bomb, sink some submarines, drop the kids off at the pool, release the chocolate hostage, plant some potatoes, give birth to a VB programmer, down the proctoscope, bake some brownies, you know what I mean (if you don’t, you’re a senile muppet, what are you doing on the Internet?).

They can’t just leave the train in the middle of the street, can they? Have you ever seen one run out in the middle of the street? I’m really curious here.

All Of Dilbert

~~Is there a Dilbert collection somewhere that has every Dilbert comic in an easily browseable manner, ideally with ratings I can sort by? 100 Dilberts per page would be ideal.~~ Ah, looks like the new Dilbert.com finally made it a reality: all Dilbert comics sorted by votes, 49 per page.

Where Can I Buy A Circus Tent?

Who sells them? The ones where elephants and clowns could fit. It could also double as a portable office.

Who Gets To Eat The Most Delicious Burger In Burger Commercials?

And where do I sign up? I’m serious.

Yeah, so that’s pretty much what’s on my mind right now. What’s on yours?

Thoughts on Google Chrome

Artem Russakovskii — Wed, 03 Sep 2008 18:40:54 +0000

So Google Chrome – Google's attempt at an open source browser, came out yesterday and I took it out for a spin. At its heart is the Webkit engine (also open source) and Google Gears, powered by SQLite (can MySQL rival SQLite in applications like this?). Here are my thoughts.

Fast – Chrome loads extremely fast, blazing even. Granted, my Firefox would probably load fast if I didn't have any addons as well. Sites like Amazon or Digg load very fast. New tabs open instantly.
Slow – http://www.blinkx.com/videos/channel:itn, seems like the combination of flash and html (or JS) on one page makes scrolling and redrawing quite slow.
Very fluid design – I love how the tabs flow around when you drag them or make them pop in or out, I love how fluid animation and resizing is.
Internal task manager – an absolutely brilliant idea. Since each tab and plugin get their own process, they don't affect each other. Any freezes are isolated to the process itself, so the days of hung browsers because of some buggy javascript should be gone gone (I'll actually have to see how well it works first).

Great Google search integration and overall Firefox3-like url bar behavior.
The word search functionality is amazing – best out of all browsers. It's incredibly fast, even on large pages, highlights all the matches, with the current one in orange, and more importantly, gives count (finally!). The search popup complements the fluidity perfectly.

History – looks great and has a timeline style. It's like reading a journal.

View Source – again, best in class. Highlighting and line numbers by default. Url access style: view-source:http://digg.com. Search spread highlighting on the right. It's close to perfect, without using any plugins.

My bookmarks, where art though? Where's the bookmarks menu? I know the homepage has them, and there's a pretty hidden way to make the bookmarks bar appear all the time (right click on it while on the home page and check 'Always show bookmarks bar' but that's not what I want. I like placing many-many bookmarks named with 1 or 2 letters onto the bookmarks bar (I found a way to emulate the behavior in the screenshot below). How can I create duplicates of the same bookmark in different places? It seems you can only bookmark in one. The interface to get around managing the bookmarks isn't well thought out, you can get to certain places only the certain way. How do you export/import bookmarks after the initial installation (I chose to skip mine)? Edit: Apparently, you can't yet.

The homepage button is missing (though it can be enabled by Options->Show Home button on the toolbar). Why is it not on by default?

I also enabled the following option right away (the main reason I use TabMix Plus for Firefox):

Scrolling is very choppy and goes in huge jumps on my laptop (not the case in Firefox).
Status bar – why do you disappear automatically when I get close to you? You can be so useful and display so much useful info? Stop disappearing!
What with the Vista-style buttons? I have Win2k menus, which I find a lot simpler and easier on the eye. Why not inherit the window style?

No Linux support. Hopefully coming soon.

No addons supported or announced yet.

In conclusion, I understand the browser is very new and will probably go through many facelifts, UI changes, bug fixes, and enhancements but it has a lot to cover and if it's going to try to rival the giants, it better fix some things fast. I personally won't start using it until some addons start showing up, like the AI Roboform (AI Roboform has actually responded to this guy about such addon possibility) and Adblock Plus ones. However, for occasional browsing, it's great. Give it a spin.
