Have shown this to my little daughter. She really likes string theory, so I’ve got that going for me, which is nice…
Yesterday’s post regarding the adoption of Perl and RegEx in early childhood has raised some questions as per to which degree we should expose our kids to potentially questionable content.
We’ve just finished a field study looking at the ability of less than two-year olds starting to learn Perl and Regular Expressions. To avoid any gender bias, we have focused on the female population. From a statistical point of view, we have been able to get 100 % participation of our dataset, which means we have a very clear proof that Perl and RegEx are for Kids. So, if you didn’t look at those, or procrastinated rather than learning Perl, what are you waiting for?
This one was not easy to solve. Running SuSE SLES 11.3 as guest in VirtualBox 4.2.18 on an otherwise entirely stable host (Linux 3.11.0 running Ubuntu 13.10), my 64 bit SLES VMs would randomly just “stuck”, consuming full CPU usage on the host system for the cores I had assigned to them. If not touched, they would remain in that state forever. Netconsole to another host did not reveal anything of value. All other machines (about 20 at the same time on any normal day) would continue running with no issues. So what was so special about SLES that made these machines hang?
We’re responsible for our children. So when suddenly, for someone happens to note a “smoking gun” like here, for severe birth defects, and the official position is to advise people to “take your folic acid” – while there is a very much smoking gun in the vicinity, in this case of Yakima, WA, this makes up for an unbelievable story.
This is amazing: A simple URL call allows you to bypass the login. What’s more interesting is how he got there.
I am probably overly abusing Better Touch Tool. As an example, while reading a book in Full Screen mode with Skim, I want to create different types of annotations but I do not want to use the menu or even the keyboard to switch annotation types. I want to keep my hand on the trackpad and do what’s needed – including saving. The issue I saw is that when using gestures, I’m not quite sure whether they actually were executed. Adding today the “save” operation, I definitely needed a simple way to display a notification on whether the given action has been performed. Enter Growl. And a very simple Apple Script that displays, using Growl, what ever has been passed on the command line. The script is given below; here’s how it works.
I’m just reading Schermerhorn et al. There’s an interesting chapter on innovation which captures the topic of flexibility vs. rigidity, or exploration vs. exploitation, that I’ve recently discussed with a group of research fellows in the context of the dichotomy of exploration vs. exploitation: “too much emphasis on exploration will yield a whole list of potential ideas for new products and processes to new clients and customers in new markets, but little pay-off . . . Conversely, an emphasis on exploitation stresses control and evolutionary development. Such exploitation can be planned with tight budgets, careful forecasts, and steady implementation. It is often much easier to stress exploitation because most organizations have a structure and culture that emphasize stability and control.” (2010, pp. 381–382)
