AdBlock Plus Ate My CPU

November 6, 2012 14:42:16.000

Over the last week or two, I've noticed that my Mac seemed to be active a lot more often than I thought it should be - and when it was, there was always a "Chrome Worker" eating the CPU. It had gotten to the point where it was impacting the performance of everything, including games. I finally started disabling extensions (I have very few) last night, and sure enough - it was "AdBlock Plus". I turned that off, and I must have gained 10 fps in "Dishonored" (which I play in a Windows VM) immediately.

Chrome also got faster - pages that had been hanging, or taking forever to load, started loading right away (even on crappy hotel wifi).

I'm leaving that extension off - whatever it was doing (and I wasn't seeing fewer ads, that's for sure), it wasn't good.

There's one more aspect of the VA Smalltalk benchmark tool to look at. If you want to start at the beginning of this tutorial section, get started here - and then have a look at the second and third installments.

Following on from last time, take a look at the pulldown menu button at the top left of the tool - it turns out that a second set of pre-built benchmarks are available there:.

You can run these the same way as we have in the earlier screencasts, and adding new tests to this menu option works as it did for the initial selection

Skyrim DLC Finally Hitting PS3?

November 8, 2012 13:24:24.000

Polygon Reports:

Skyrim content that has been available for the Xbox 360 but delayed for the PlayStation 3 for months might soon be on its way, according to a tweet Skyrim developer Bethesda sent out today. The company tweeted: "To update, we're also close on new Skyrim content for PS3 and PC" and "Thanks to all our fans. We think you'll love the new stuff. We know it takes us time and thanks for all your support and patience!"

I wonder how much Sony regrets the very different architecture they picked for the PS3 at this point - I suspect it's at the heart of a lot of these problems. Not because it's technically inferior, but simply because it's so different from the PC and XBox setup that a proper port has to do more than cross compile...

ST 4U 307: Pinpoint Benchmarking

November 9, 2012 10:23:34.381

Today's Smalltalk 4 You looks at more pinpointed benchmarking in Smalltalk - measuring the execution time of a specific block of code. 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:

Benchmarking.

If you have trouble viewing that directly, you can click here to download the video directly. If you need the video in a Windows Media format, then download that here.

You can also watch it on YouTube:


Today we'll look at more fine grained benchmarking in Smalltalk - measuring the execution time of a specific block of code. Quite often, the profiling tools tell you where to look, but you then need to dig deeper to figure things out (for instance, the profiler could point you to a specific method, but that method might be long). It's pretty simple - wrap the code in a block, and then use Time>>millisecondsToRun:


results := Time millisecondsToRun: [blockOfCodeToTestHere].

Now, you'll want to run that block a number of times and average the results to get a decent snapshot of what's happening, but that's all there is to it.

Satire Imitates Life

November 11, 2012 15:38:04.657

Next time you have a few friends over to watch a movie, unhook the Kinect from your XBox - the copyright fascists are about to start doing headcounts. The sad part about this is, back in 2006 there was a satire written about that:

In November 2006, a site named BBSpot wrote a story about how the MPAA lobbied for home theater regulations, arguing that a home theater in your living room allows your friends to not buy their own DVD:
“Just because you buy a DVD to watch at home doesn’t give you the right to invite friends over to watch it too. That’s a violation of copyright and denies us the revenue that would be generated from DVD sales to your friends,” said [MPAA spokesman] Glickman.

It seems that you just can't make stuff up when it comes to copyright law. Microsoft just patented that idea:

Microsoft has filed a patent for a technology that would let Kinect detect how many people are consuming content at a given time [...] would monitor how many people are in the room when a game or piece of entertainment is being displayed and “take remedial action” if the number of user-views licensed is exceeded, according to the patent application.

It's at the point where you're not sure whether we should laugh,or cry.
