The turning point against pro corporatism for me after years of schooling in economics happened a few years ago from a simple argument that I can’t get out of my head.
Technological advancements in an owner controlled factory leads to fewer employees. The same advancement in a coop leads to more leisure.
I know it’s super simplistic, and ignores pluses and minuses on both sides, but it really seems to sum up a fundamental problem with increasing efficiencies in society, and I can’t help but wonder if we are failing to capture the leisure that society has made possible.
Right, the main problem is relentless competition. I get we need some of that, but do we have to sprint full speed into some dystopia? Not so sure there. Coops don't make it because I guess they can't compete as well as one boss making all decisions, and so we get more and more products faster, except quality of life just keeps going down (not in a material sense, but in a well being sense).
I’m still on the fence about closing the door for a short task like pouring milk. My understanding from the physics of opening the door, you’re mostly already replacing all the air in the fridge with air from outside the fridge. So convection already did its job of robbing your fridge of cold. Closing the door to open it again a minute later just gives you a second convection inducing action for air that might have been trapped the first time.
I would love to see someone at the level of technology connections do a breakdown of the physics here, and where the likely crossover point point is for different kinds of fridges. My current (probably illformed) belief from the suction and imagined resulting air exchange of all the fridges I’ve lived with is that leaving the fridge open on the order of seconds is better than opening-closing-opening-closing in terms of cold loss.
"In theory but the benefit would be pretty negligible i think. Let's say for argument that most food is water and your fridge is 25% food and 75% air. The specific heat of air is 1 kJ/kgK, specific heat of water is 4.2 kJ/kgK. But also the density of air is 1.2kg/m3 and the density of water 1000kg/m3. Assume 1 m3 volume. So that would be 250kg food and 0.9 kg air. To change temp by 1C would take .9kJ for the air and 1050kJ for the food. So the air in a fridge holds a fraction of a percent of the total thermal mass of the contents. Whether or not that air changes temperature by a few degrees won't change things much at all. You would spend far more on balloons that you would save on energy."
The air exchanges in seconds, yes (as evidenced by the post-door-closing suction), but the air doesn't stop flowing through the fridge as soon as the air changes once, and the air enters warm and leaves cold, so (by conservation) heat is being robbed from internal surfaces. So you're still losing more heat by leaving the door open longer.
Door open --> Door close --> Suction --> No further heat loss afterwards
Your question seems disengenuous, and it’s not clear you read the post. But I would reckon many of us are having very similar experiences with how our daily activities are shaking out. The author’s story likely resonates with many devs here, who lament the loss of what many of them found interesting or compelling about the work they did.
Indeed, I'd read the post too quick, have been annoyed lately by the many front-page poges that seemed either trivial or not related to tech, and assumed it was the same. Now I did read it properly, and I reckon the feeling is well rendered and it does not feel that much out of place.
Well, hope the author will post a follow up in a month or two titled "how I eventually found joy again coding with an AI assistant".
> I believe you. I don’t need the details. Tell me what we're changing.
Yeah, for me in these situations it’s often about messaging to stakeholders, and so management in general feels like the problem has been addressed. I do think there’s one important thing missing from the final statement of the post, that he sort of covered briefly when talking about too much process, and that is what is the tradeoff/cost of implementing the change we’re making. Engineering is fundamentally about tradeoffs, and any significant proposed change requires some tradeoff and all too often I see management not asking about this explicitly. I’ve had enough once in a blue moon errors have retros, where the team decided it made no sense to make changes, and others, where the cost was high enough it was worth increasing workflow headaches. I think these tradeoffs being explicit are important at the director and above level, since there are potential real impacts to the team, and that is the level to deal with morale or headcount pressures due to changes to processes.
I had to stop reading one of my favorite authors when I was doing infant duty with my oldest. The books kept getting thicker, and I could no longer one hand them comfortably reading either end of the novel due to the book's balance. I found a kindle mostly solved my problems, and I could keep reading again one handed.
That said, it never occurred to me to just cut up my book, so I could continue to read it comfortably. I think I might have chosen to do so though, since I find the tactile nature of reading a physical book to be more memorable than digital. Where the words sit on the page, and the act of turning the page, the smell, all does something to my neurons. For my junk novels, I don't really care, but for the authors I cherish, the closer to the printed word I can get the better the experience I have, and the more memorable the writing in general.
I saw 10million quoted recently, and that sounds about right. 300k is a super safe withdrawal rate for that much money and you have a pretty comfortable life at that income level most places.
There’s a great lecture on giving lectures by an MIT prof. He says you can give no more than 3 ideas per hour, and you must repeat yourself at least 3 times for each idea. And while, part of his thesis is because people might miss something due to their attention, and needs of the group vs individual I think his experience is still highly relevant. I know that I don’t learn as much unless there’s room for almost boredom. I find there is a feeling similar to boredom that I have to experience to really internalize something. It’s almost like I can feel the neurons rewiring (though I suspect it might just be an emotion that encourages the energy expenditure necessary for learning). If I skim, or do doubletime, then that feeling usually never comes, and there’s a good chance my future recall will be poor…
Good to be skeptical. Remember, though, that there is zero cost to displaying ads. That means they get bundled at places like indeed. If you’re HR and have 3 openings, but have 4 ads you can run for less than the price of 3… Personally, I might run an ad for some kind of triple threat that has no chance of finding someone.
Also, the cost of screening ad responses is near zero compared to 30 years ago.
So we have economics that encourages ghost job listings. Personally I’d like to see big taxes on job postings scaling for company size, maybe duration too. Would solve this particular problem.
I had an interview once for a firmware position dealing with (relatively) high wattage transmitters. They wanted to know how I’d deal with some conditions where I’d need to turn off the power quickly. After talking a bit about my experience with hard real time deadlines, I sheepishly asked why they didn’t have diodes to mitigate the problem. I think it was one of the questions that got me an offer. Apparently having firmware engineers with even minor EE background and will think about analogue design is a little uncommon.
Today, I’d ask about more ways to push the responsibility away from the firmware to stop catastrophic failures. If the debugger pauses the CPU you can’t use the CPU to regulate things. I’ve worked on things where the failure mode can be explosive and it makes dev really harrowing if you can’t rely on hardware interlocks.
>Apparently having firmware engineers with even minor EE background and will think about analogue design is a little uncommon.
They often don't have to know how the nitty-gritty of the HW works. HALs are used everywhere, and some of them abstract a lot away. I've interviewed embedded SWEs that couldn't explain how the tri-state buffers work within GPIO.
It’s the caps that fail. Electrolytic caps have the highest failure rate of any passive component. My team tries to avoid them in our designs as much as possible. But you’re right, caps in a good design can easily last 20 years, making a power supply the longest lasting component of most builds.
My go to source for reviews was always jonnyguru.com but he closed up shop. Not sure who’s actually doing in-depth performance and component reviews these days.
