Comment Re:1.5V alkaline vs 1.2v NiMH (Score 1) 243 243

And yet I can't recall any device that didn't work happily with the 1.2v supplied by a rechargeable NiMH.

To add to this good statement: Alkaline batteries have high internal resistance, so when they are highly loaded, their voltage drops dramatically (and therefore become useless to the device they are powering). NiMH have low internal resistance and can delivery drastically more amperage before their voltage drops. Many devices completely work with 1.2v just fine, but alkaline batteries drop below that too easily.

Comment I've done this very thing... (Score 1) 353 353

I built a generic piece of a larger system that I thought would be a good thing as open source. I convinced my boss that since we were using open source software as part of our big system, we should give back to the community, and he agreed. I organized the source with proper licensing into a package and my boss handed it off to the lawyers - explaining the above - for review. A few days later, they came back and said "no problem, post it". And I did. That was the end.

I suppose some of this depends on how prick-ish your company/boss is, but mine, thankfully, is pretty laid back about this sort of thing.

<rant>Here in Seattle they keep raising taxes and adding tolls in high traffic areas. Yet, the money just disappears into the void. I haven't studied where it goes but I *know* they make more than enough money to fund schools and teachers. And still, my kid who goes to Redmond high school has class sizes that are too big, has a couple of classes in temporary structures that have been there for a few years, and a science teacher that can't answer questions to the stuff she teaches because she's not even remotely a scientist. This same science teacher also has a workload far higher than normal teachers; She has no planning period and therefore is never prepared for class. As a result, my kid hates science when I think she would otherwise enjoy it. I do my best to re-teach what she should have been taught in the first place. It doesn't help that her science book is an incomprehensible piece of shit. </rant>

Legitimate question: Does https://www.random.org/ seem to be a good place to get *really* random numbers? I'm curious if it's suitable for reliable random number generation. Based on the site it seems so, but I was wondering if somebody smarter than me could answer that with some degree of confidence.

Comment I post useful stuff for _me_ (Score 1) 190 190

I find it difficult to enter into an existing project for various reasons - sometimes I can't get a build environment working, or the code is such a mess I just don't feel like trying to figure it out. There are other reasons too - like elitism of the existing contributors. But, I've written code that I use frequently that I don't see anybody else has really done - or at least, done well. My code might be too specialized for most people (Oracle PL/SQL mostly), and it's certainly not perfect by any stretch, but I use it regularly and usually winds up in the code-base of places I work. The comments I get from those places are: I wonder why nobody else has done this?

One question I have though, is I would like to make my code more well-known to those that might be interested. I have no idea how to promote it. How does one go about advertising without looking like a narcissist?

This was written by some guys that really don't know how computers work. Seriously. They have not studied algorithms nor understand how Java/Python works under the hood, nor how the operating system I/O subsystem works (specifically caching). How this wound up on /. I just don't get it. If you are doing string concatenation, at least try to do it the right way.

Comment Mac/Retina (Score 1) 385 385

The Macs with Retina displays are second-to-none. Visually spectacular that nothing comes close to. Get a model that has the memory/processor you want and put VirtualBox on it for Linux and run it full-screen. I don't do physics, but I spend most of my time in the Linux VM. It's wonderful. I'm not a fan-boy, but the Apple hardware is worth it.
