I have a shell script based on ImageMagick that gives a PDF a "scanner" look. I typically open the PDF in Master PDF Editor to insert an image of my signature, then pass it through my script. When I do need it, it's rare, but

I have a Linux NAS with 6 7200RPM HDDs in a raidz2 ZFS pool, and the local fs read speed on large files is 7 times faster than GbE, about ~930 MB/s. So while this wouldn't saturate a 10GbE link, it would still be greatly beneficia

Yes, what if they did? In fact what if they resold 100% of the F@H compute power to buyers? That argument doesn't lead where you want it to go. It's the antivirus companies that are rubbish.

If Norton 360 installed Folding@home, would you call F@H a "cancer"? No, you wouldn't. The true cancer here is pre-installed antivirus software such as Norton.

The biggest problem with Zelle is the low limits. I cannot send more than $2500/month. One time I paid a contractor about this amount, and then, well, I couldn't use it for a WHOLE month until the limit reset itself... Very, very

A lot of us InfoSec folks consider this very good practice to be 100% open about how security technologies are deployed. Ever heard about security by obscurity? It confers a false (dangerous!) sense of security, and prevents your security s

As an ex-InfoSec engineer for 12 years, my only concern is they seem to have no process to recover from a defective or destroyed HSM. But other than that it's quite good (though I have only skimmed the blog post.)

If you don't control miners you have to do something even harder: You would need to control or force 100% of exchanges, 100% of merchants, in fact 100% of all participants in the Bitcoin network to reject tainted coins. See how this ca

You are both right: 5 miles is about 20min on an electric bike, but 35min on a traditional bike. I do a 4.8-mile trip on a class 3 ebike (28 mph) consistently in 14 minutes in San Diego north county.

By this guy's definition, gold is a Ponzi scheme. 1. People invest into it because they expect good profits, and 2. that expectation is sustained by such profits being paid to those who choose to cash out. However, 3. there is no exter
