TL;DR. Ride sharing / taxi vs car ownership breakeven is at €10 per short trip (5km or less), but only worthwhile if I could totally get rid of the car: only 25% of car ownership cost is fuel, 75% or €5000 is maintenance + depreciation.

my calculations (sorry if formatting is off)

depreciation:

13000 purchase (5y old ex-lease car)

1000 after purchase: change of timing belt + water pump etc

resale: 5y after

6000 ?? residual value

1800/y depreciation

annual maintenance:

250 (1000 for 2 sets of seasonal tires every 4 years)

1000 (insurance + road tax)

40 official checkup

200 basic service (oil, filters)

1000 ?? fixing things + parking + road tolls + tickets

2490/y maintenance

fuel (europe)
6.5l/100km diesel
20.000km annual mieage
1.3 €/l diesel (don't buy at highways)

1690/y fuel

garage 75/m (comes with my apartment)
900/y garage

total cost: 6680 €/y

total cost: 0.334 €/km

I also figured I do 500 trips during school year (40 weeks, 12.5 trips per weak)

total cost: 13.36 €/trip

This is surprisingly high. I need to find a way to make more trips :)

OK, that includes holidays in which I do half of my annual mileage (10.000km) but in the end most of the cost is fixed: depreciation + maintenance. Sadly, even at free electricity EV is not going to be much better. Only 100% ride sharing will bring a cost reduction that will influence decisions.
My side project over the last few years was more or less the deciding factor in me getting hired at my current employer and my previous one.

Being able to demonstrate turning an idea into reality and talk about technical (and design) problems I encountered and how I solved them seemed to be much more interesting to interviewers than most of what I had done at my previous day jobs.
Not sure what you dug up, but I’m not aware of anyone with an interest other than proving “see, we weren’t the bad guys”. Since the Holocaust is a historical fact, historians without revisionist goals have no reason to debate its existence. Research into the extent and details of the Holocaust are perfectly acceptable. Side not, the absolute vast majority of German society is on board with this limit of freedom of speech. It’s part of the constitution even.
It’s already being used by ec2 in the us-east-1 and us-west-2 regions.

I loved this documentary. Watched it with my daughter who is an 8-yo wannabe a marine biologist someday. What always troubles me is that in the end, the film maker just lets the octopus died. I wonder what stops him from providing a sanctuary for it. Another moment in this I found strange is how he didn't want to intervene when the shark came after and ate the octopus arm. Maybe his thought is more about survival of the fittest and didn't want to be the decision maker in the natural food chain.
It doesn't take imagination. Rather than trying to imagine the issues, try to develop an eye to see the problems that are already in front of you. And don't start with grand ambitions. Start with the problem in front of you.

One way is to have hobbies, side hustles, volunteer work, whatever. As long as you're doing something that requires solving problems that are different from your day to day programming job, you will find a constant stream of problems that maybe you can improve with a bit of code.

Some of my side projects are directly related to my work, but most of them aren't. I'm working on something right now because someone in my life needed advice on digital security, and it turned out to be not an easy problem to address.

That “conflation” is the exact same thing as the University’s reputation. If they don’t value their reputation, fine, but these bad researchers are only getting press because they are attaching the univerity’s name to their ideas. That’s not something to blame readers for. And if there are researchers at these universities that oppose them, it’s up to the university and other researchers at Stanford to stop their name being use if they disagree with its use.
The old manager adage is "Hire people smarter than yourself", I don't see how this can be satire, everything he says is very reasonable if you believe that these interviews are a good way to filter candidates. Satire would try to make some jabs at it but there are no jabs against the interviews in this article.

I don't think the parent poster is giving any judgement to how people spend their time, only qualifying how.
It's a little ironic that this is on "hacker" news since I think that the original "hacker" ethos wasn't that you built things just to impress recruiters.

If your goal is career advancement, then it is fair to acknowledge that some projects won't be useful for that. But there's plenty of other reasons that people work on side projects besides just career advancement. "Just for fun" might be the most famous reason, that is I believe how the Linux kernel started.

While maybe big companies won't value side projects directly too heavily, there's still a good chance that if you learn new things and try to build interesting stuff, that it might open new doors in all sorts of unexpected ways. But there's no guarantee.

I also think that full time coding jobs can be a lot of work, and people shouldn't feel too pressured if they don't want to have side projects, because they have other things like a busy family life or non-technical hobbies. But for many people, programming can still be fun and interesting, especially outside of the usual corporate routine, and that's all the motivation they need to pick up a side project. That to me is really what a "hacker" is, not a leetcode grinder climbing the ranks at FAANG.
Apparently MIT medical also has a good article on how to choose mask materials.

I’m an introvert, and I find social interaction draining. I am only truly happy and relaxed when I’m alone.

But I also recognize that social interaction is necessary to get work done, and I don’t expect to be truly happy and relaxed at work in the first place. I can’t wait to get back to the office.
Re composting toilets, there's a 4-story laboratory in Auckland NZ with a compost system - built 2004 (https://www.scoop.co.nz/stories/ED0404/S00113/pm-opens-uniqu...).

Normally councils here are VERY stuck in the past but in this case they had no ability to pipe sewage (due to critical pipework already surrounding the building). The real main issue is councils and their consultants all being stuck in the past and not wanting to do anything new which many regard as a threat (I'm a designer/planner so see this every day).

Money is the only way such people understand the world so we have to help people see that waste has a very high cost - polluted rivers and oceans cannot easily be repaired but as everyone owns them no-one has responsibility.

There is some interesting stories of how people achieved it here: https://www.reddit.com/r/fatFIRE/top/?sort=top&t=year
I think it's important to break the conversation clearly into two parts: Here's what could be true about aliens if we're largely correct about physics, and here's what could be true ignoring that constraint.

The problem is people want to have really muddled conversations about that. The people having the second kind of conversation yelling at the people having the first kind of conversation is probably the most frustrating element of all, especially when they strike a morally superior pose which is, IMHO, entirely unjustified.

If you want to ignore all current science and astrophysics when you discuss aliens... fine. Be my guest. No sarcasm. I have some beliefs on that front myself. BUT... you need to be aware that you're basically engaging in groundless speculation, and in particular, you have no grounds to be yelling at people about their groundless speculation.

We can have a much more grounded discussion about what aliens could look like if we are largely correct about science. And there's no need to accuse people about being "arrogant" if they choose to have that discussion, because frankly, of the two, it's the more interesting one. The "well, what if we're wrong about everything?" may seem like fun for a moment, but there's no there there, really. What if we're wrong about everything? Well, what if we are? What if we're all just in an ancestor simulation... but the descendants running it are super-advanced honey bees running their ancestors and we just happen to be around? Well... what if? There's nowhere to go, or if you prefer, there's nowhere you can't go, which is actually the exact same thing.

On the other hand, if we stick to biology and cosmology and relativity and science in general, we can have all sorts of interesting discussions. What about that result on Venus? That's a question rich enough to build a concrete career on. What would aliens look like in our real universe? How much more advanced could they be? Would they, in fact, build rather human-sized spaceships that are apparently capable of crossing the interstellar void, but not flying around in our atmosphere without crashing into things? Would they in fact need to keep kidnapping humans over and over for decades on end? Sensible discussions can be had on these matters if we start from a concrete base. The whole "But what if we're, like, wrong about everything and we're, like, actually soap bubbles floating in the wind?" discussion has nowhere interesting to go, because it creates just one big undifferentiated and indistiguishable mismash of what ifs.
Microsoft is one of the very few companies that'd benefit from Linus losing market share.
I don't think he is denigrating it. He probably phrased it badly, but he meant you did side projects like a hobby just as well you might have done hiking in that time.
Im not sure if I agree or disagree that blindly throwing more money is the right approach, but I can say I think we did a poor job of using the information we had early on (age, weight being major factors) and using that to selectively protect the most vulnerable. Locking down elderly care to an extreme level and having the social support and food to do so, might have saved more lives-years than keeping everyone at home.

All in all, it just wasnt feasible to tell the elderly to stay home while the rest of the world continued humming. This was one way to get everybody to care.

I wasn't disagreeing with what you said about flattening the curve, I'm saying its meaning has changed in some usages, from what you described to something else.
One of my favorite things when working from home pre-pandemic used to be to go to a quiet bar with only a couple other patrons and sip a beer while working, or to go to the public library and work quietly in the group study room. Even without being 'social' it was my way of being social.

Now, even though I wake up without an alarm, eat clean, and exercise every day my productivity has tanked. There's some deep, human alarm buried somewhere in the reptile part of my brain that is saying 'things are not right...you are not ok...things are not right,' and it's been doing it since March. I can't seem to find a breaker to switch it off.

There's only so many times you can walk around the block.

Are you aware of the concept of market power, switching costs, barriers to entry, and market lock in?

If so, then that should enlighten you as to the explanation for this.

> did it actually matter?

Yes. It matters, yet still did not change consumer behavior, due to the concept of market power.
Of course it should be. You have always been paid based on what it takes to keep you at the company rather than your work output or where you live. If you live in the middle of no where your options suck so it doesn't take much to keep you.

Man this is taking a ton of stuff out of context.

Satya's "when people say you're working from home, it feels sometimes like you're sleeping at work" is about a lack of work/life seperation, not productivity. The office has invaded your home, so it's like you are now sleeping at office.

Other concerns- such as not having downtime between meetings, or a commute to transition between work and home- are real problems. He actually states that the solution is to build time in to your day to regain downtime.

I didn't get the feeling he is down on remote work at all, but pretty balanced. I wish he'd been even more positive about remote work, but I never got the feeling he was negative at all.

Yeah. Consider how much more light a chain link fence lets in than a screen door.

With the limitations around PG poolers that's not always that easy :(

I've worked on a number of very large postgres instances - the backend memory usage wasn't usually a major issue for the very large ones (i.e. not schema sharded ones, where it's a large issue). The TLB miss ratio however was a major bottleneck on them, even with huge pages (perhaps even because of huge pages, because the TLB for huge pages used to be so small).

The project is bigger than Tom Lane ;)

I think it's been pretty clear that threads have more advantages than disadvantages (which are substantial - hello mmap_sem) for quite a while. But that doesn't necessarily mean that we should have changed it a couple years back - as you say, it's not a small change, and it'll cause some disruption. There arguably were (and perhaps are) more crucial issues.

> That's going to be one hell of a job to change now though.

Yea. But it's doable. Personally I think the PG internal changes not the hardest parts - that's having to deal with all the extension out there. Both to ensure that they are adapted, but also managing the pain of having to deal with all the API evolution.

This is a great point. I've been almost exclusively WFH for 5 years now and I feel myself getting antsy now -- because social interactions quite simply don't exist outside of meetings at work.
Netgear has been dissopointing for me. I like to load up DD-WRT but it's getting harder to make things work these days. One of the feature I want is ability to see usage report per device, especially for kids devices. This is so badly implemented in most routers. Netgear app for this is an absolute joke.
> To give an analogy, it’s like you’re worried about a frame crushing car crash while driving in a school zone. Or fiddling with your seatbelt tightness and worried it may not be optimal for safety, when the main determinants of car safety are actually personal alertness, time of day, etc. But if you adopted a whole bunch of wrong behaviours while driving a car it would absolutely reinforce anxiety!

> To some extent anxiety is an irrational process. But I do think it has some basis in the physical world and by really going over what risks are and what risks aren’t you can tame it and reason with it somewhat. Good luck!

As an aside, I chose to move to a dense urban region in large part because I suffer from car anxiety. In particular, I get really anxious that the moment I stop feeling anxious my alertness will drop and I'll be in a terrible collision. Although full on panic attacks are pretty rare from this.

But the question isn't whether soft measures have an impact. It is whether a hard lockdown, closing shops and restaurants, forcing people to stay home, works. If the same result is achieved without those a hard lockdown, we should stop considering it a useful option.

That does sound like a Windows bug. In that case, disregard my previous message.
This "return to normal" narrative is starting to make less and less sense to me. It presupposes that there is this one special, immutable state called Normal defined as "exactly as life was right before the pandemic", and that we have to somehow get back to precisely that state.

It's looking more and more like this deadly virus is going to be part of our lives for months or years to come, if not decades. So, instead of ignoring reality and trying in vain to get back to this idealized "ISO standard normal," maybe we are going to have to change our definition of normal. We're going to have to normalize things like WFH, wearing masks, social distancing, avoiding large indoor gatherings, instead of treating them as temporary measures. The world changes, and our concept of normal will necessarily change along with it.
> Remote meetings are great. They tend to be shorter, get to the point

My team loves meetings. Every question asked was an excuse to gather a bunch of people around a desk and talk for almost an hour. Precious hours wasted in useless meetings. The best thing that happened with remote work was that my team realized that a single message or email was more than enough 99% of the time and now we don’t waste so many hours in those useless meetings anymore.
It doesn't work that way - the SAT solver takes all the bids and maximizes revenue for the auctioneer. What variable would you try to maximize/minimize in an election?
Thank you! I'll bookmark this comment as I'm trying to take stock of what would be most helpful.

There are two kind of opposing directions I see a need for:

- "Beginner Unity" take tailored for an Engineer. E.g. let's talk about the input system, frame-rate independence, overview of rendering/lighting, a high level overview of the editor, etc. And get that out of the way.

- Satisfying what I might call a thirst for idioms/best practices from a SWE perspective. E.g. separation of concerns in MonoBehaviors, using ScriptableObjects, etc. Also maybe overview of things like "Should I still use Git with Unity or look into Collaborate?" and the like.

My current sense is that I'll end up toeing the line between these two. But, regardless of this specific series, I enjoy writing about best practices and software patterns in anything I'm working on, and Unity is no exception -- so stay tuned!

In my above example, by doing nothing you pick winners.

Not in all situations, doing nothing is doing nothing. Take the famous trolley problem. By doing nothing you pick 5 people to die, if you do something you pick 1 person to die. One of those will come true, either inaction or action will determine which. But that also means your inaction is an action of yours to force an outcome. This doesn't necessarily mean it's the outcome you want or the outcome that is preferred. Inaction can be the worst type of action to take in some scenarios, but it is the action of non-intervention that creates an outcome regardless. Inaction doesn't mean you consent to the outcome either.
Yes. Also N95 filter .15 micron particles better than .3 micron particles because their motion tends to be more Brownian and less ballistic, leading to more particle/masks interactions where they can get caught.
