We did a lot of blind testing, but blind testing takes more effort and we were always swamped. Usually the engineers would just test things ourselves, and then I would give my boss a blind test for the final approval.

At my last company, we tested tons of combinations of class D modules with various power supplies, and the best sounding results tended to be with linear power supplies. Don't get me wrong, there's tons of tricky stuff when it comes to the subjective side of audio, so it may be at least partially placebo effect. But we pretty consistently found that off the shelf switching PSUs sounded worse subjectively, even if they measured the same on the bench.

I haven't been doing audio for a while, so I don't remember more of the details. But audio signals tend to need all their power in short bursts all at once, when a low frequency bass note hits for example, and so the transient current tends to be much more important than a stable voltage rail. A lot of switching supplies do not optimize for this. Well designed versions can both sound great, but a cheap linear supply is going to sound much better than a cheap switcher. Audio is stuck with 1960s technology for the most part anyway though.

Hi, I'm Paul, I'm a software engineer. My latest project is an IoT home automation system and dashboard in React that ties together a lot of microcontroller projects I built. I've previously designed high quality pro audio equipment and developed software in the structural engineering industry.

Hi everybody, I have about six years experience in product development and embedded systems. I've primarily worked in the pro audio industry, but I'm interested in any type of embedded work, firmware, IoT, manufacturing, etc. For the past year or so, I've been doing a mix of developing my own products and some contract work. I can help with prototyping, product development, firmware development, bringing new products to life, and getting things to market.

Hi everybody, I have about six years experience in product development and embedded systems. In the past, I've primarily worked in the pro audio industry, but I'm interested in any type of embedded work, firmware, IoT, manufacturing, etc.

I suppose the implication is that the "you" in the title is your conscious experience and in reality, you are the sum of your conscious and unconscious processes with all of their inherent perceptual distortions.

Not sure if this one is going to be any easier, but I've been slowly going through Max Born's Atomic Physics after I picked up it used for really cheap. I like the way he goes through each step historically and presents quantum mechanics as a progression of discoveries based on what people were thinking at the time, which for me made it easier to reason about.

I've had multiple bad experiences with Amazon Logistics. They routinely ship things 2-3 days late and update the tracking information with some nonsense about "attempting to deliver the package but no one was home," which I don't buy for a second. They also routinely deliver to the wrong address. One time tracking information was updated to "delivered" and my package showed up at the building next door to mine 3 days later. I came close to canceling prime the last time this happened.

I've been planning a side project with a lot of those features. That's exactly how I think about my budgeting and that's exactly how I would like to allocate my money. I'm really not aware of any way to do this currently, apart from a lot of manual work in a spreadsheet, which is annoying and still requires restraint in spending. Mint isn't even that helpful when it comes to budgeting because their alerts and categories are always inconsistent and they change categories that you've set for no apparent reason. Not to mention the ads.

Unfortunately, getting data from bank accounts is a pain due to bank security. The approach I was going to use just to get started was to export Mint's data as a csv, and then build an app around that until I read up on the bank transaction formats that would let you pull your transaction history. Not ideal, though.

I think tvanantwerp's point wasn't that you shouldn't attempt to know yourself, but that you should try to do so in a way that doesn't ascribe labels arbitrarily, such as "morning person" or "evening person". Not all aspects of identity can fit into such boxes. Otherwise, there's quite a risk of reifying the label and thinking that everything the label describes must describe you too.

Thanks for the advice. This is basically what I've been doing for the past year, every spare second I've had devoted to side projects. I don't think my expectations are too out of whack because whenever I've gotten a code challenge from an employer, it was pretty easy and I made it through to the next round. But it probably takes longer to build up a portfolio that is actually meaningful.

Not really. I'm in audio, so mostly analog with a bit of microcontroller experience.

I guess it might be easier at a bigger company like that, so I could focus more on those types of roles. Thanks for the ideas. Just have to keep at it I guess.
