Asterix Love

   Posted by: wkossen Tags:

a false sense of securityLately there has been a lot of discussion about this poor little character, the asterix: *. One example of this is this site. This character has been a very frequent site on every login screen you might encounter. It hides your real password (unless you actually had ******* as a password…) The question is whether this is good or bad practice. In this little post I’ll give you my opinion on it.

The original argumentation was to hide the password from peeking eyes. Look over someone’s shoulder and you know… then, you might look at what someone is typing on the keyboard and know as well. Especially if someone is typing slow. The added value is limited. In fact, security by obscurity isn’t real security. As it turns out, not seeing what you are typing increases the likelyhood of making mistakes. This is frustrating, but also costly. Unlocking accounts, retrieving passwords by e-mail etc. is timeconsuming and therefor pricy. Now we have two sides of the scales, which one is heavier?

In fact, that may not at all be the question. You could argue that the asterix’s make people feel good. They’re not only nice to look at, but also give a (false) sense of security, something people like (and not just after 9/11). The feel-good-factor hasn’t been taken into account in all the discussions I’ve read on the internet. Even if the added value in terms of real security is limited, what about making people feel safe (even if they aren’t. You want safety? Shut down that computer Now!).

Another factor that hasn’t been discussed is the simple fact that if we were to change this habit, it would take a very long time to reach an asterix-free world. There would be a mixed environment for years which might confuse people so much they call on the helpdesk anyway. No savings here. Is it really that bad? Or should people learn to type without looking and improve their skills that way?

Even further, one could (and I do) argue that the password itself isn’t a very good idea. There are better ways of securing stuff from unwanted access. Multifactor authentication, biometrics (although there are strong arguments against that one as well. maybe worth another post one day), smartcards, PKI, etc…. If we’re going to change at all, let’s not just do the superficial and aesthetics…

As you see, I don’t have the answer. do you? I hope you will comment on this post and give me your views on this little subject.

Cheers…

More on (bar)codes…

   Posted by: wkossen Tags: , ,

In my previous post I talked about barcodes and QR-codes. One of my dear commentors, Aldon Hynes, asked me about the Microsoft Tag in relation to my post. I didn’t hear about that before so I went right at it. What’s that all about?

qrcode versus Microsoft Tag


Microsoft Tag is another system for tagging offline objects with a code or tag and allowing mobile users to connect to online resources that are linked to the tag. You see the MS tag pointing to my domain here. It’s, ahemmm, ugly. I guess taste is personal…

Visualization Methods

   Posted by: wkossen Tags: ,

Periodic table
Image via Wikipedia

There are lots of ways to visualize information, concepts, thoughts and systems. In fact there are probably near endless ways to do so. I use some in my day2day work like mindmaps, tree-diagrams and network-infrastructure-maps. I have been using some UML related diagrams and all sorts of layered architectural maps. however, I’ve not used even 10% of available techniques.

I very recently (today) found a website that gives an overview of a lot of available visualization methods in a visual form that is appealing. In fact, visualization techniques within a periodic table. I found this site as it was added to http://Twine.com, a site I am a member of since quite some time and that does come up with great stuff from time to time. This was one of those moments. In fact, this is a new site, but I wanted to share it with you anyways…

Let’s give you the URL now: Periodic table of visualization methods. I would certainly give this site a 10 out of 10. You might, too… If you find methods not listed there, let me know!

I hope you like this post.

The Blogger’s Challenge

   Posted by: wkossen Tags: , ,

Blogging isn’t necessarily very easy, in fact, it’s pretty hard, especially if you want to create good content and post regularly. On the Entrecard Blog I created a post (and it was in fact accepted!) about my blogging-strategy. Since I’m getting some nice replies, I really want y’all to read that post. I’m not going to create duplicate content, so here you just get the link. I hope you like the post. Don’t hesitate to comment, either here, or on Entrecard.

And here’s the link: The Blogger’s Challenge

Information Overload, The Solution?

   Posted by: wkossen Tags: , ,

Don’t you agree? There is too much information. Too many websites, too many documents and way to much e-mail. There is just too much information. You know why? There are three simple reasons for this.
