Did you know that using Java Agents is inherently multi-threaded? I nearly cooked my processor finding out....
By Andrew Pollack on 03/17/2005 at 09:09 AM EDTI discovered something interesting yesterday. I'd written some code for a project I'm working on dealing with spam management. The code examines native mime, parses and pulls out target URL's and does some things with them. This means a huge amount of text processing. Instead of doing it like I had in LotusScript, I took advantage of Java's "StringTokenizer()" class for the heavy lifting. What I noticed when I ran the agent, was that both the primary thread and the hyperthread on the processor maxed out to nearly 100% for the duration of the agent. I'm guessing that concurrent to the parse work going on in one thread, the indexing and I/O work was being done in another. This has interesting implications for high performance code.
As to my processor --- I started getting overheat warnings. When I opened the machine, I saw that the Zalman fan was packed with soot and dust. I've cleaned it, but now I realize I need a new tube of thermal grease before I can really crank this machine up and work it hard again. Ah well. For want of a nail....

The truth is, I haven't had much to say that was worthy of more than a basic social media post -- until today. For my current work, I was assigned a new laptop. It's a real powerhouse machine with 14 processor cores and 64 gigs of ram. It should be perfect for running my development environment in a virtual machine, but it wasn't. VirtualBox was barely starting, and no matter how many features I turned off, it could ......

Certainly it should have been addressed in the Trump, Obama, Bush, Clinton, Bush, and Reagan administrations -- all of which were well aware of the implications of a pandemic. I want a military prepared to help us, not just hurt other people. As an American I expect that with the ridiculous funding of our military might, we are prepared for damn near everything. Not just killing people and breaking things, but ......

This is not quite a scam because it's technically legal, but it's run very much like a scam. This company works with a few "clients" that have vast repositories of copyrighted images. The trolls do a reverse web search on those images looking for hits. When they find one on a site that looks like someone they can scare, they work it like ......
