<p>Are you disagreeing with the explanation? I am curious why.<p>It makes sense to me.<p>Move slowly and deliberately while avoiding big mistakes. As opposed to moving fast and making big mistakes which by comparison is slower.</p>

<p>What's the alternative?<p>I think it's the right call since there isn't much competition in GPU industry anyway. Sure, Intel is far behind. But they need to start somewhere in order to break ground.<p>Strictly speaking strategically, my intuition is that they will learn from this, course correct and then would start making progress.</p>

<p>This was a nice short read. A simple (temporary) solution, yet a clever one.<p>How was he managing the instances? Was he using kubernetes, or did he write some script to manage the auto terminating of the instances?<p>It would also be nice to know why:<p>1. Killing was quicker than restarting. Perhaps because of the business logic built into the java application?<p>2. Killing was safe. How was the system architectured so that the requests weren't dropped altogether.<p>EDIT: formatting</p>

<p>What I have noticed companies do is resume emails after a year or so. They probably think people would forget about unsubscribing them after a year, and for the most part they are right.<p>If I catch any of these email lists not respecting my unsubscribing, I immediately mark them as "spam".<p>Gmail then doesn't send them to my inbox anymore. I don't think just one person marking them as spam hurts them, but at least I feel gratified and my ego is satisfied.</p>

<p>as I was reading the article I was thinking "Oh, you mean labeling your goals differently will cause you to think about them differently and hence, will cause you to plan differently". That is, there would be something <i>tangible</i> that would be different.<p>So I tuned in to learn more about the technique but I was disappointed to learn that there's nothing more to it at least in the article.<p>It just suggests to re-label your goals differently and think of them as "quests", but it doesn't mention anything more.<p>I really want to learn how to make my chores and boring goals fun so that I can go about them doing them. Can anyone please shed some light on this?<p>I have tried to gamify my work but it hasn't worked for me.</p>

<p>I loved my fitbit zip a lot!! Unfortunately, the smartwatch trend took over fitbits too and all of them are now just smart watch types.<p>The thing is I am a vintage watch enthusiast and I only wear vintage mechanical watches. Thus, leaving no room for smart watch both from a space point of view and fashion point of view.<p>Hence, my options are quite limited when it comes to pedometer. I either go with cheap alternatives (which are quite accurate btw), or none at all.<p>I wish fitbit brings back clip-on devices as a first class citizens in their lineup.</p>

<p><i>PNNs resemble neural networks, however at least part of the system is analog rather than digital,
meaning that part or all the input/output data is encoded continuously in a physical parameter, and the weights can also be physical,
with the ultimate goal of surpassing digital hardware in performance or efficiency.</i><p>I am trying to understand what format does a node take in PNNs. Is it a transistor? Or is it more complex than that? Or, is it a combination of a few things such as analog signal and some other sensors which work together to form a single node that looks like the one we are all familiar with?<p>Can anyone please help me understand what exactly is "physical" about PNNs?</p>

<p>This one really stuck for me: "focus on something special, then expand from there".<p>I have time and again fell victim to fulfill all the prerequisites before I begin to attempt to understand a topic. This is a mistake I have made repeatedly. I now understand why this is tempting to do and why it is a mistake.<p>It is tempting to do so because you feel things will come easier to you if you fulfill the prerequisites first. But the problem is that there is just not enough time. AND, it actually may not be even necessary.<p>It is a mistake to do so because you are wasting time and ultimately it may not be necessary after all.<p>Even in a field such as pure mathematics (I have an MS in pure Math), it is okay to skim through some of the background material and understand it intuitively or even non-rigorously, while focusing on what you want to actually learn.<p>It took me a while to learn that and I am glad it is being repeated here by such an accomplished professor.</p>

I am not discounting the benefits plastics have brought to medicine such as hygiene, but I am concerned its environmental impact.<p>I also understand that industrial plastic waste is probably an order of magnitude greater than that in medicine.<p>But I am curious what sort of test a biodegradable/sustainable plastic would need to stand for it to replace traditional plastics.</p>
