The best natural gas power plants are 64% efficient. A modern furnace is around 95%. Sure electric restive heat is 100% efficient in your house, but the whole system us much worse.

Of course electric can come from many sources, if your is renewable at the time resistive is good. However you might also be using some old 1920s coal generator that is 10% efficient (these still exist, but are only used in the worst emergencies)
Great! Best UI I have seen among similar apps. Works on phone as well.
The newer refrigeratants that require higher pressures are much better for ozone and have a lower global warming potential.

I've got a couple hundred LC's under my belt but I would still definitely appreciate something like this. Do you have a discord in mind or something else?

Currently gainfully employed still, not sure if being laid off is a requirement but I'd like to keep my skills sharp just in case.
Heat pumps are also known as "reverse cycle air-conditioners".
Don't buy a Tesla and you'll be fine. I work in auto insurance and the other OEMs actually care about safety and testing of software. Tesla has the most bugs by far.
For me the size is a major advantage. Traditional controllers are an ergo nightmare for me. The width of the controller means my hands are at a much more natural angle and the shape and balance of the deck is very well thought out.

The steam deck replaces gaming laptops for me. Gaming laptops have always been hot, noisy, and highly failure prone. The deck is downright dainty in comparison and doesn't require me to carry a mouse, controller, and clunky power brick as well.
I switched from C++ to Java 20 years ago, and never looked back. Although I've been using Scala the last 7 years.
> CANBUS was broken reliably, and if my memory serves me they even had a car you could take a shot at hacking yourself.

This statement shows a fundamental lack of understanding of how automotive computer networks operate.

The CAN bus is just a network. It's an industrial control protocol that's been adopted by the automotive world. It doesn't offer security by design, it's intended for use in limited environments where all hardware on the network is known and trusted. CAN provides methods for prioritization of devices, that's it. Any security is left to higher layers of the stack.

There is no such thing as "breaking" CAN, you just physically connect to the network and you're able to talk to whatever controllers are on that network (most modern cars have multiple CAN buses connected to different subsets of the vehicle systems). At that point it's about the security features implemented by the devices on the network.

> Any car running CANBUS is vulnerable to a potentially fatal attack. They have not resolved this.

There is nothing to resolve at the network level. To put it another way, almost every computer that's ever been hacked over the internet was running Ethernet but that's just as irrelevant as CAN in cars.

If you are able to physically connect to the network, you can talk to and potentially spoof devices on the network.

> A car 25 years old has 99% of the safety features of a modern car and, in good working order, will protect you just the same.

You couldn't possibly be more wrong. Pick your favorite vehicle from 1997 and look up the crash test videos, then compare against a similar recent model.

Here's the most popular vehicle sold in the US, the Ford F-150, from 1997 (https://www.youtube.com/watch?v=_i5EmJBaGeQ) versus one from 2016 (https://www.youtube.com/watch?v=Cou88zi4pMY). You tell me which one you'd rather be in.

You might say, correctly, that the 1997 F-150 is particularly bad, but here you can see a 1997 Volvo V70 versus a 2009 Volvo V70 (https://www.youtube.com/watch?v=msnJK0ce-VM). Volvo has a reputation for building some of the safest vehicles on the road, and even those twelve years show substantial gains in crash performance where the older car's passenger compartment is clearly compromised while the newer one's crumple zones work as intended.

> Or maybe I just don't worry about it because the probability of anything greater than a minor fender bender killing you is pretty high even with modern tech.

Again, absolutely wrong. I say this as someone who's flipped a truck off the road at highway speed and walked away with minor abrasions and bruising from the seatbelt and a few cuts from broken glass as the rest of the truck got ruined but the cab stayed intact. My anecdote is of course statistically meaningless, but the data agrees. Crash fatality rates have consistently trended downward from the '80s until 2020. The main reason modern vehicles have gained so much exterior size without gaining nearly as much interior size is all the space taken up by modern safety equipment, crumple zones, etc.

It depends in my experience on what "news" we're talking about and the depth of the information. Almost all I'm seeing online is made to engage and engage people, some more and some less, and that definitely matches what parent is describing. Maybe you're talking about different kinds of content.

I stopped consuming "news" i.e. CBC, CNN, Guardian, and the likes two months ago and I feel objectively happier and spend less time endlessly refreshing the page. I read the occasional in depth article because I feel like it doesn't have quite the same effect.

>The “defund” label is perhaps the worst marketing of any social movement ever. Nearly everyone would agree with the main nominal ideas - more oversight, less violent responses, more accountability and moving resources away from militarized police and towards social work, specifically psychological interventions.

It's a motte and bailey. The sentiment behind "defund the police" goes well beyond the set of things most people agree with, but its proponents retreat "we actually agree on 95% of the issue" when challenged.

Yes, we do. But the remaining 5% is completely unacceptable.

The problem with going through to the offer stage with companies you do not want to work for is that this is likelier to limit your options rather than increase them.

This is not a very strong prior, but re-applying after rejecting an offer can indicate that you are using the company as a fallback and may bolt as soon as you get a chance.
Yeah, assisted GPS is great. I remember ye olde GPS consumer receivers taking minutes at a time to find a location while modern phones are of course much better and a lot of it is down to having a network connection to help out. It got so much better so fast that it's easy to forget how janky it could be!
I didn't explain clearly... AC systems don't have a single efficiency number - they have different efficiencies depending on the indoor temperature, the outdoor temperature, and the number of kilowatts you want delivered.

You can generally design any AC system to work efficiently at any specific combination of those variables - but if any variable deviates far from the optimum design point, efficiency will drop.

So the real question is, not "I want an efficient system", but "I want an efficient system when it is 20F outdoors, because that's the temperature most of the year".
Yep, here's a spec sheet for a unit I'm looking at as a drop-in ducted replacement for my existing system -- it has all of the models listed, but I'm looking at the 4-ton unit (12k btu per ton, so 4-ton = 48k BTU, hence the MDU18048): https://mrcool.com/wp-content/dox_repo/mc-uni-perf-ss-en-01....

It takes 7kw at 17ºF to provide 48k BTU. There are 0.293W/hr per BTU so 7,000W = 25k BTU "in" and 48k BTU "out" or a COP of 1.9. At -15ºF, it's using 5.9KW but can only produce 28,500. So a COP of ~1.4. Still better than electric resistive heating but not by much. At 40ºF, the COP is more like 3.3 which is in line with the very efficient numbers.

Fortunately my 99% design temp is ~8ºF and my area only sees 20hrs below zero per year, so this will work just fine for me.
I've had bouts of unemployment lasting a year and a half. It's really hard to focus on side projects when you are worried about being able to pay the rent and health insurance and your pittance of unemployment insurance has run out.

My advice to anyone in the tech field is to try to have a lot of reserves, because tech is cyclical, and layoffs are inevitable, like every two to five years.
The last 5-10 years have seen crazy money. I think most of us will see pay cuts sooner or later. Definitely when you get in your 40s+ you're likely to get a pay cut for each new job, unless you're management or architect or similar.
Good question, I think there are many different approach on solving running multiple services. So it boils down to what you need, and what works for you. One advantage might be the ease of use. Using Porter you don't need to know anything about Supervisor, systemd or other more technical implementations. Porter abstracts away these things so you only have to write a simple .yml file.
Agreed! I have lots of complaints about grad (as well as some things I think are improvements, at least hypothetically), but "it'll be used to do more layoffs" and the wilder "it was designed to make it easier to lay people off" are both nonsense.

This sounds extreme, but none the less I agree people should try to change something.

Most recommend to start exercising. Easiest way to do this is to simply say I'm the kind of person that runs / bikes / works out (don't give yourself the option to decide). Simply say on Saturday's I do a run (rain or shine), then say Tuesday's and Saturdays, etc. In no time you're doing it 3+ times a week.

From one good habit others will follow, since you'll have learned how to stay consistent.
I’d like to politely point out that you are speaking to the geopolitical coordination challenges related to deployment, not the technology itself.

Those are real, important issues to be worked through, and to your point, and they are better served by a multi-stakeholder approach that values climate justice.

There is research and work needed both on policy and the technology aspects of this.

They don't do that anymore. They offer subscriptions to curated lists of games. You used to be able to purchase old games from Nintendo, but now you can't. (At least on the Switch)
I would just add one thing here, aside from echoing the comments on the great writing. Everyone needs to focus on saving when they have a job for uncertain times. I've found it incredibly helpful in the last year with some savings in the bank, to ward off the uncertainty and chaos around not having a job, and taking it a bit easy so to say.

Saving at least 20% or so of every paycheck is good standard advice for rainy days. But, also not to keep any debt.

Lastly, it's not that terrifying these days to not have employment in the software industry. Things will turn around as long as you work on developing your skills. Staying positive is good advice for the short and long-term. Because everything will work out, and we usually stress a lot more than we really should.
Was it a company that also did gas boilers?

If it's not a company that solely does heat pumps, I have heard a lot of contractors will give outrageous estimates because gas is simpler for them and they don't want to do it without the huge markup.

I had ground source heat pump installed with vertical wells in a city by a dedicated geo installer. The cost with tax credits came out not much more than a high end gas furnace and water heater. Going airsource would have been even more cost competitive, especially with the federal tax credits in place starting in 2023.
I'm referring to the capitalists as thought of in 21st century economics, not some outdated 19th century Marxist/extreme left-wing echo chamber (lol, 'haute bourgeoisie', are you even listening to yourself?). People who deploy and risk their capital to produce services or products are capitalists. e.g My local grocer is a capitalist or my grandfather running a family farm is a capitalist. I can tell you for sure my grandfather is not a millionaire, I'm not so sure about my local grocer, but I doubt it.
In this case, if the individual is diagnosed with depression, taking away an escape from reality like Facebook doesn't solve the depression. Like they said, a depressed person will find something else to substitute Facebook. Depression needs actual treatment in most cases. The analogy to vaping and smoking doesn't exactly work.
>There's a ton of things that can go wrong in a car which can cause an accident.

And pretty much none of them ever do if the driver doesn't react exceptionally poorly. Even the spectacular stuff that the internet absolutely loves to hand wring about, like a wheel falling off for whatever reason, almost always results in the car coming to a controlled stop on the side of the road. The conversion rate between "failures" and "meaningful harm to anyone or anything is abysmal."
I actually don't think that's as much of a problem as you'd think - I did nine months off after 2.5 years. I just wouldn't say you've been searching and not getting jobs - much better to say that you've interviewed at a few places, but you're very focused on finding a company whose mission and team you're excited about (particularly if that's true). If they accept that as true, then you're creating a positive sort of scarcity of yourself, as opposed to framing it as jobs being scarce and you being desperate for one.
I think this happens to a lot of people. Especially for people who really enjoy the work they do, rather than see it as a necessary evil to put a roof over their head.
Agree.

The problem imo is that cops have an insular culture and are trained to control situations. That control is often an Illusion. They are also often exempt from some of the procurement rules that apply to other government entities. So they tend to accept handshake claims from people identified as “good guys” through some connection or the salesman’s former on the job status.

Another issue is that they don’t pay for or maintain technology in many cases, and the organizations tend to want to fund overtime, gas and bullets over all else. Police rely on grants to buy stuff with tight timelines. So there’s a tendency to blow the federal grant quickly on something cool that some “good guy” promises.

It's not so easy when people actually want to move to your country. I'm not from the US so I have no particular interest in defending it, but if Scandinavian countries were even a fraction as attractive to immigrants as the US, I'm sure their immigration systems would be a shitshow as well.

My previous comment was flagged so let me add some more context around "Musk claims".

Remember Musks claims of FSD being X months away (for years), and SpaceX will be cheaper by orders of magnitude, and Twitter will be open to all free speech, and the cyber truck, and new roadster, etc etc? The point is, Musk has shown himself as unreliable and we can hardly trust his claims.
I was laid off in April 2020 as well, and while some of my experience matches the author's some of it was very different.

Being laid off was not a relief -- it was terrifying. All indications were that a severe recession was coming. Frankly, it was quite surprising to me that companies were hiring at all given the uncertainty. It was not obvious at the time that broad sectors of the economy could seamlessly move to 100% WFH. It was also my first experience in fully remote interviewing.

I am a software engineer over fifty. I also have three children two of whom were in college, and my wife works in a travel related industry which was very much affected by the pandemic.

Given those things I approached my job search aggressively and with a sense of urgency, and I made it out OK. I was out of work for about two months and accepted a role at flat comp.

Being laid off is profoundly lonely. I was part of a mass layoff (approximately 2/3 of my company was laid off.) So while I was not alone in that sense, we were all very much alone together. Where you had been a team, you were now five people looking for jobs, each with their own problems and constraints. My wife could not have been more supportive, and yet the process of interviewing and landing a job is one you have to do by yourself. One of the hardest things is to maintain an upbeat outlook, and yet it is so necessary because no one is going to hire a miserable sad sack.

On the other hand, I had no stigma whatsoever attached to the fact that I had been laid off. Part of that might have been that the size of the layoff was such that anyone with any glancing familiarity with the place I was at would know that 2/3 of the company were laid off.

One thing that I would emphasize would be maintain your professional network in good times and in bad. I got a number of good leads that way.
In 2012, Facebook deliberately made people depressed as part of some evil experiment.

I may just be cynical, but I don't see any reason why AI judgement won't be the next cruentation. AI decisions are based purely on learned biases, which may be effectively equivalent to gut feelings. There will be many opportunities for AI-determined suspicions to be used as a determination of guilt in lieu of real evidence.

"The AI finds it likely that you committed the murder."

It doesn't have to be this way, but given the perpetual misunderstanding and misapplication of AI, I think it's likely to happen anyway.
APL might be an outlier here. For the rest, I think the difference lies more in the standard libraries of those languages than the languages themselves. Yes, differences in core language design start to matter when you are considering performance, or structuring larger applications, but for simpler scripts, you're mostly dealing with the standard library.

On the other hand, differences will start to show them selves after you spend a while noodling with your script, refactoring it a couple of times and deliberately seeking out opportunities to use language-specific features in the process. This expands the exercise to something more like "a language a week" instead of "a language of day", which is obviously a bit more of a time commitment. But if you want to get value out of a "polyglot" programming exercise like this, I think that's what you really need to do. Otherwise I think you learn lessons that are only correct at surface level.
True, though I don't think it has anything to do with AI - the filtering mechanisms are much simpler than that.

That said, I like early-stage startups, so less of a problem with that kind of thing.

The problem is mostly a cultural one.

In my personal experience, the automotive industry has a problem with aggression and dishonesty, both of which seem to go hand-in-hand.

Both of these cultural traits tend to have a negative impact on quality and safety.
> there is variance in how resistant people are to the influences of those situations, and it varies both by individual and by the specific crime

How is this not just another way of saying "some people are inherently criminal by their nature"?
This is not true. You need a healthy balance of 10x improvements (which Rust has with the whole borrow checking business) and aggressive advocacy.
Sand Hill Road is a road in the SF bay area where a lot of VC firms have headquarters. People use "Sand Hill Road" to refer to the SF VC industry the same way people use "Wall Street" to refer to NYC based finance.

I'm not really what the official definition of blitzscale is (or if there is one). I assume it means scale (specifically grow head count) really fast.
I just got laid off and I went through a layoff in the early 2000s and it was brutal. Had to do contract work with tech I didn't like and now with the added pressure of having kids that I have to care for financially it's definitely more stressful.

One thing I'm doing different this time around is that I'm building a project that could be useful for some friends and might actually scratch an itch. It allows me to get back in the latest technologies and adds something to my portfolio.
> It can be used in the style of simpler languages like Go and is almost as safe as Rust in a much faster manner.

What does this mean, exactly? Usage in the style of Go requires garbage collection and being safe like Rust (without GC) requires a borrow-checker, and as far as I know Free Pascal doesn't have either.
From a cursory scan, this looks like it doesn't support key wrapping -- the private key ("identity" in age's parlance) is stored unencrypted on disk.

This is arguably a non-issue for most use cases (disk access is "game over" under most threat models), but it's nice to have e.g. for sharing configurations between multiple machines over a public channel (like a dotfiles repository). It would also bring this roughly up to "spec" with what other password managers do (i.e., in terms of requiring a "master" password that unlocks the vault).
