Phone Malware
Well, this is a cheery sounding bit of news:
Today Robert Templeman at the Naval Surface Warfare Center in Crane, Indiana, and a few pals at Indiana University reveal an entirely new class of ‘visual malware’ capable of recording and reconstructing a user’s environment in 3D. This then allows the theft of virtual objects such as financial information, data on computer screens and identity-related information.
You download a camera app, but it's actually this thing. Awesome.
ST 4U 326: Loading Applications in ObjectStudio

Bizarre Gaming Issue
I ran across this yesterday - I have a second monitor attached to my Mac, and I use Parallels (Win 7) to play games that aren't out for Mac. I set the big screen to be the primary, fired off Parallels, and then started XCOM: Enemy Unknown. And... the mouse pointer is registering dozens of pixels off. To hit a button, I have to move the mouse way to the right. If I play in mirrored mode (less resolution), everything works fine. No other game does this too me - I'm wondering whether it's a Parallels artifact, or something else?
Patents are no Longer Helpful
It's not the concept of patent law that I object to; it's where things have gotten to. Unless we adopt "loser pays", there's really no way out of the crap sandwich world we now live in. No patents would - absurd as that sounds - be better than what we have now.

More Upgrade Fun with VisualWorks
This change happened back in 7.8, but since we are only now upgrading, we ran into it while going from 7.6 to 7.9.1. Take code that looks like this in VW 7.6:
point := 4@-5.
In 7.6, that gives you a point object. In newer VW? It gives you the message #@- sent to 4 with an argument of 5. Same thing with fractions. Not hard to fix - just look for senders of #@- and #/- and then use a rewrite rule to fix them. Better yet, it was turned up by our unit test suite :)

ST 4U 327: Memory Monitoring in VA Smalltalk
Today's Smalltalk 4 You starts looking at the basic memory monitoring tools available in VA Smalltalk. If you have trouble viewing it here in the browser, you can also navigate directly to YouTube. To watch now, click on the image below:

It can be useful to get an idea as to how memory is being used as parts of your Smalltalk application are running - VA Smalltalk provides some tools that allow you to have that look. First off, you'll need to load some applications using the ApplicationManager (EsMemoryTools)
Once that's loaded, go to the launcher's tools menu, and start the monitor:
If you start it, not a lot will be happening - after all, we aren't really running anything but the base image. Try something - here, we loaded an image file using streams:
See the changes? You can use this to better effect when running your application (or hotspots in it) to see what's going on.
Need more help? There's a screencast for other topics like this which you may want to watch. Questions? Try the "Chat with James" Google gadget over in the sidebar.
