Unlockers

My new office is the nicest place I’ve ever worked. It’s gorgeous.

As part of a more intentional office strategy, not everyone comes in at the same time. For occasional “everyone in at the same time” events we have extra overflow space.

But since all the desks are shared, there’s a clean desk policy. Anything you don’t want to take home goes in a locker. You pick an empty locker, put your stuff in, set the code and lock it. When you return, unlock it with the code. Simple!

I love lockers because I can use them as dead drops. When I had to return a kiteboarding kite or send someone a present it’s more fun to put it in a locker and message them the combination. Sneaky fun!

But I just found a terrible hack:

The lockers unlock for any code.

I discovered it accidentally when I went to open the wrong locker and put in my code. It opened and I, a fool, thought “That’s so weird that they put in the address of our last office as the code!” Then I moved on, until I did it accidentally again. Then I went hog wild and tested that ANY four number opens it.

I’ve let the admin team know but I also feel the need to go put presents in every locked locker until they get it fixed.

DreamHost is making my life way more complicated

Argh – normally I like everything DreamHost does. They had a history of just making my life easier over time. Their plan was simple: unlimited email and storage for your website, a reasonable price.

But now, for the second time, they are taking away a feature that I use heavily! DreamHost is killing catch-all emails! This is terrible for me.

The short version: I own this domain and I get or send email from from anything@morelightmorelight – so honeybooboo@morelightmorelight gets to me and I could send you a mail from DarkCrushingVoid@morelight… This is fun, but where it is really useful is in dealing with all the damn signups online.

Everyone online wants you to sign in or sign up! The reason why isn’t always that they love you and want you to be a member, it is sometimes that they want to track you and sell your details to other businesses. Imagine that! Sometimes they are nice but they just don’t have great security and someone steals your email address from them. That’s how you get all that spam!

Stop for a minute and give Have I Been Pwned a check for your email address. Yeah.

The emails I use for talking to people I love and care about don’t show up here. For example:
Image showing that my primary email hasn't been in a data breach
But when I am forced to register with a service, I just make up an email address with their name in it and I make up a password just for them. When they get breached by hackers, they hackers can’t use that email or password on other services to get into more stuff. For example:
Image showing that an email and password associated with adobe was stolen from the adobe servers

The password with adobe and the the email address are disposable to me.
I filter out emails from places that have been breached by hackers.

And all is good! I have unique emails per place to log in, I have unique passwords per place to log in, and I have a way to respond to data breaches. But now, DreamHost is turning off this feature for me.

They will delete my email account in October if it isn’t converted over to a different email account. I have to figure out a way to create email accounts for all the logins I’ve had over the years or go change them on every site. It is going to be an incredible pain in the ass. So now, I have to start figuring out how to respond.

My likely plan:

  1. learn how to download all of my emails and get a way to analyze them.
  2. Figure out all the unique email addresses I get email at and mark them as keepers and personal. This will take coding.
  3. Create a main personal account
  4. Upload all my history back to this account and figure out how to sync that back with Thunderbird
  5. Create all the other personal accounts and forwards from all the other personal accounts to the main personal account. This will take coding.
  6. Create business accounts and forwards for each of them. This will take coding.
  7. Create a general new throwaway scheme for login emails
  8. Investigate whether it’s time to move to hosting that gives me more control or adapt to this and concentrate on other things in my life.

That last one is also important. When I was younger I did a lot of flexing in tech to do things myself so I could be super independent. This taught me TONS of things and is great! However, I can’t do everything, so I now make compromises so I can spend time on what matters most.

That’s the part that irks me. I am fine with adapting to the new business reality at DreamHost – but they don’t have a plan for me. I’m going to have to build my own tools and figure out my own way. I can do this, but I don’t want to! I’d rather spend this time building a website or helping people or being with my family.

Free Kiera Wilmot

A young woman conducted an unauthorized science experiment with an unfortunate result. At school early, before morning bell, she was in the lab and mixed some common household chemicals in a bottle. There was a small explosion that injured no one.

She has been expelled and is being charged with a felony.

I am Kiera Wilmot. I was enthusiastic and bored in high school. I did unauthorized experiments, some of them very very stupid. I was well known as a smart person who did very very stupid things in high school.

I was not expelled or arrested, I was given guidance and understanding and was often yelled at for doing stupid dangerous things. The authorities at my school did not screw up my life by putting a felony on my record or kicking me out of school. I stand with Kiera and other troublemakers.

As a former troublemaker and soon to be parent of a future troublemaker I am very worried about the zero tolerance policies at our schools. They are crazy and would leave me a drain on society instead of a productive taxpayer.

The ethical car is a deathtrap

Non-nerds are talking about machine ethics because Google’s driverless cars show up in a New Yorker essay:

Within two or three decades the difference between automated driving and human driving will be so great you may not be legally allowed to drive your own car, and even if you are allowed, it would be immoral of you to drive, because the risk of you hurting yourself or another person will be far greater than if you allowed a machine to do the work.

That moment will be significant not just because it will signal the end of one more human niche, but because it will signal the beginning of another: the era in which it will no longer be optional for machines to have ethical systems. Your car is speeding along a bridge at fifty miles per hour when errant school bus carrying forty innocent children crosses its path. Should your car swerve, possibly risking the life of its owner (you), in order to save the children, or keep going, putting all forty kids at risk? If the decision must be made in milliseconds, the computer will have to make the call.

Heady stuff, right?! We must not be allowed to drive our cars because machines can drive them better. We’ll get standards for car ethics from a government agency.

I’m reading Bruce Schneier’s excellent “Liars and Outliers” so let’s look at this from a security perspective. If you have mandated ethics for machines, I understand that as a single set of rules that cars have to obey. We would have to decide, as a society, if it is better to save ourselves or kill the 40 kids. We have to come up with an algorithm that a machine could use that we could agree with.

The trouble is, this isn’t how ethics work in our brains. Our minds aren’t algorithms. They are a quorum. We make decisions by having different parts of our brain shout their opinion. Self preservation shouts. Pity shouts. One of them shouts louder and that’s how we decide to swerve off the bridge. Or that’s how we end up living with our decision.

So this isn’t how you’d get a machine to make a decision. You need a replicable algorithm, something that you can hold up in court to avoid liability. The problem here is you have a system – and those are hackable. Hackable systems get hacked.

What happens when the choices your car will make are all predictable? People don’t have a regular response to situations, they are very variable. Your ethical car will be making predictable responses to situations. Predictable responses are easy to manipulate. So you can expect hacking of those situations. You can expect people to manipulate the ethical responses of your car to their own ends – and you won’t have an input because you aren’t as trustworthy as a car.

But this is kind of a smokescreen, isn’t it. The article isn’t really about the idea of driverless cars having to make decisions. Driverless cars can’t make a decision between the bus full of kids and your own life. So what is this article really about?

Passwords – hard to do, important to get right.

Over on Staunchly Technical, Nate gives a rundown of his password scheme:

“Unique” memorized password: Google, Password manager(s), home server (exposed to Internet).

  • These are “master key” systems – if these are compromised then the hacker effectively has the ability to get my password to anything else. As a result, the password for these is not used on anything else (really, I ought to have a separate pw for each of these, but since they’re all so unrelated I’ve just got one for all 3).

Random stored individual passwords: All things potentially damaging (banks, brokerages, prosper, IRA, etc)

  • These are randomly generated 10-character passwords – they might get sniffed, but they’re not going to get hacked. These get saved in the Firefox password DB and are also in my password manager program (Keepass, for anyone who cares)

Work password: all things work-related

  • Everything I do at work requires me to change my password every 3 months – since I have trouble with multiple passwords anyway, I just set them all to the same thing. Only one of them can be accessed from outside the intranet anyway, and my VPN is protected by a keyfob.

Easy (but still relatively secure) non-changing password: social networks and anything else that can’t cost me money or too much heartache.

Useless password: sites that I really don’t care about and/or don’t trust.

Nate’s a really smart guy, so he wouldn’t be spending all this time thinking and writing about it unless it was important.  Why is he using so many different passwords?

What’s going on here

He’s segregating them into security zones.  The most important one is his email or his password system manager.  If someone gets the key to his email they can reset passwords to his bank or investment accounts and the password reset email goes where?  That’s right.

When Gawker’s poor security and  taunting of 4chan led to the usernames and passwords of every user being posted online, it was a very big deal.  Most people use the same username in many places – because they want a sense of identity and reputation that can follow them around.  Or maybe it’s just easier to remember.  That’s probably why most people use the same password everywhere.  Like their bank and gizmodo.  So those folks are having trouble.

Not Nate.  All they can do is post nasty comments on social networks under his name, and he can reset the password and get past that.

Also, not me.

My Suggestion

I tend not to use the same username on every website.  I register something using the site itself as a key.  So if my email is mk @ gmail.com (it isn’t) I would just use the gmail “name+” trick to register at lifehacker as mk+lifehacker@gmail.com. This lets you know who is selling your email address  or getting hacked into.

I manage my passwords differently, in a way you might use.  I use a passphrase and then I use select letters from the site to construct a unique password per site.  Like so:

My passphrase is a memorable poem or sentence. Let’s use the first two lines of Yeats’s The Second Coming

“Turning and turning in the widening gyre,The falcon cannot hear the falconer”

I take the first letter of every word to make my password: “TatitwgTfchtf”

That’s a big password and easy to remember!  But you want your password to be unique across many sites.  Let’s do that by pulling the site into it.

Lifehacker has 6 consonants and 4 vowels.  Let’s add those on to the end and the beginning: “6TatitwgTfchtf4”.  Even if someone gets your password and knows another account of yours, you have a unique password at the other account.  You could also put the first and last letter: “LTatitwgTfchtfR”.  Whatever you want to put a little extra randomness in the mix.

Want to see how strong your current favorite password is?  Go to the MicroSoft password checker and try it.

Practice good password safety – I don’t want to get emails from your account asking me to help split up your Nigerian fortune.

Volunteer Your Computer to Keep Privacy Possible

The good folks over at Wild Bee have an excellent article about how you can use your computer to help the world while you sleep. Lotsa people run SETI@home – I think it is because of the screensaver. Instead of a looking for aliens, you could help political dissidents in repressive regimes, protect anonymous whistleblowers, and even protect our intelligence agents overseas. Install TOR and volunteer your computer for global privacy.
