That list of Russian wishcasting is completely absurd. The UK is going to rejoin the EU and the EU is going to collapse? In 2023? The 4th Reich? Elon Musk who literally cannot be president will become president in a year without an election? Of some random states that joined with Mexico in a civil war?

How can you take any piece of that list as something reasonable when it shares the same origin as some of the dumbest things I’ve seen printed?
Linux was definitely a worse system back then. But probably not necessarily 10x worse. It definitely got comparatively worse as some Unix vendors added interesting features, but Linux has spent the past couple decades catching up because there was so much money coming in from the people switching from those Unix systems to Linux. :)

Ask HN: Advice for a person in their late-20s switching careers into tech
Hi all, its 2023 and AI is going to take over a lot of jobs. So what advice would you give, to someone who is in their late 20s, for switching from a non-tech related career to tech?

Alternatively if you are a person in this field and would have to do things again from start then what/how would you do things differently given that its 2023?
While money supply is one of the factors, most economists don't seem to think it is the largest factor nor the most important. The world supply chain is still catching up from covid shutdowns. The auto industry is a perfect example of this. There are still waitlists for many new vehicles. Which has also caused increases in the used market. Now that supply chains are finally starting to catch up, we are already seeing prices fall in the used market, despite overall inflation.
It has been on a downward trend before covid19. For example, American life expectancy is lower than Cuban life expectancy.
In a supply shortage (which is the housing market in most areas), prices follow the purchasing power of the buyers, not the goods' value. And since we've had years of 0% interest rates and accompanying mortgage rates, purchasing power was astronomically high even for owner-occupier buyers. Property investors add even more high-power buyers to the market, and further reduce the supply.

The only way to bring down housing prices is to out-build the demand -- which no constructor will do voluntarily, because it's a guaranteed loss proposition. Personally, my only hope is that remote work will even out prices between low-value and high-value areas -- but I'm aware that proximity to the job is not the only factor determining the value of an area.
Agreed! And to your point, I tried to include a couple of activities with a low barrier of entry in my above post. You could argue that bodyweight-only YouTube workouts have an even lower barrier of entry than running (you don't even need shoes!).

Also, a small nitpick: if someone is starting from zero, I'd argue "effectiveness" probably shouldn't be the goal...it should be finding an activity the person loves and wants to keep doing. From my own experience: For years I hated fitness and avoided it at all costs...until I found a gym with group fitness classes that I fell in love with. From there, losing weight was easy because I was just doing something I loved.
I’ve thought for years that the ideal would be a very free market with very little regulation combined with a basic income and a strong social safety net.

Let people go wild and try stuff and do whatever but raise the floor up to the point where people can recover from failure and where the less fortunate are not suffering.

This kind of “social capitalism” could be freer and less regulated than what we have now.
Remote sensing is severely limited by latency and throughput of the downlink, as it needs to push mountains of data in a tiny window when the satellite is passing over the ground station once in a while. "Internet in Space" will help to remove (or reduce) this limitation.

This resonates with me. Also in management with a similar style. However, I'd like to take a little tangent from there in case you'd want to elaborate on what it means to "get to know" people as part of the humanistic approach.

One of the ways that I've learned to practice respect is actually not really getting to know people personally too much. I've been manipulated before by "leaders" who try to use personal information like family needs or other goals as a fake carrot that is not in their power to exchange. As a result I have a pretty "no questions asked" policy on the privacy rights of my direct reports when it comes to approving any time off or facilitating whatever it is they want to do with their careers, and it doesn't require "getting to know them" beyond their own voluntary sharing in private. Sometimes it will grow into a closer relationship but it totally doesn't have to.

Maybe it's an extreme reaction to the bad taste from interacting with folks who like to pretend that work is a family. I just don't trust workplaces enough to be fully vulnerable anymore, and by extension would never demand that another employee be unconditionally trusting with their full humanity, because it is never a two-way street. When the company wants to mess with livelihoods it does not need to seek permission, so it is unfair to ask for the disclosure of personal information beyond what is necessary to carry out the work.

For just one more recent example, I fell for the advertised inclusive corporate culture by putting my pronouns on my Slack profile (having never been publicly out as a queer person at work before), I experienced weird behaviours from people that made it harder to do my job normally. So I ended up going back into the workplace closet because it's just easier to project what "regular" folks want to see in order to solve problems efficiently.

I'd love to hear your take on healthy boundaries, because sometimes I wish there could be more connection with people in the workplace besides the naturally occurring camaraderie that arises through direct collaboration and the inevitable small handful of friends with similar values. Is it possible to have a deeper connection with everyone as a general approach?

Heavily agree with this. The internet of 1998 or even 2006 is very very different than the Internet of today.

However, I think this desire for fragmentation and divisiveness was inevitable. People were always in conflict with each other; we just didn't have the means to butt heads like we can now. If the Internet existed in 1920, I think we would (a) have some amazing historical artifacts, and (b) see a lot of the same behaviors we're seeing today.

> If we have a period of inflation, with increased wages (obviously with a painful lag),

This isn't obvious, wages can drive as well as lag inflation.

> but house prices remain stagnant with no increase, would that bring them down in real terms

Yes.

> without a “housing crash”?

Perceptually? Likely. Substantively? Only if it was a long, slow inflation, and therefore a long, slow real-value decline.

> Could this be a “good thing” and does that even make sense?

It’s the same thing, requiring the same conditions, as the real-value decline without inflation, but with inflation.

What I think you actually want is wages rising greater than both inflation and housing prices (not real decline in housing prices as such), so that wages rise with respect to housing. But the problem isn’t defining the output on that level, anyway, its dealing with housing supply/demand to make either scenario happen.

> Ranging from randomly wake up from sleep in my backpack

This is so much of an issue in Windows that LTT basically took the stance to tell everybody to buy a MAC instead because they just can't take it anymore. It seems to be more an issue with gaming laptop, not that they wake up more, but that they go through their battery so fast that you charge it overnight, and by the time you take it out of your backpack, the battery is already dead.

Personally it's not that Linux "just works" for me, it's that Windows doesn't either anyway. Once, I had Windows 7 not being able to find my user account and I had to open Windows in failsafe mode and play in the bios.

The worst I've had happen to me in Arch is the DNS not working after an update and having to manually edit it in a file. The thing with Arch though is that when something breaks for you, there's a ton of other people with the same problem so it takes 2 seconds to find an answer. Ironically, Ubuntu, Debian and Mint always gave me much more smaller problems. Like KDE on Kubuntu makes the os bar disappear after I play a certain video game in steam, or my monitor stopped working one time after playing that game, etc.

It used to be hard. I just spent a day in c# and gql figuring out how to do API level tests with a new framework. But when you get it working it's ever so much faster.

Still playing around with the right level for this but this is currently nice as it gives me compiled type checking and refactoring. This is an example/extraction from another project which uses react as the client. Wasn't big on cross language api level tests yet for speed of development, as that's a tradeoff. Redundancy vs even more framework.

I strongly disagree with this. You need progressive overload of muscles to continue growing, meaning you should be in state of doing 12 reps max of given exercises per set and not more (6-10 reps range is better).

Once you start being able to do 12 push ups, muscles growth stimulus becomes low, and it becomes more about suffering than benefits.

The only people I know of that are using Windows 10 at this point are primarily gamers, as they're the only people who didn't let the automatic update to 11 happen. To be fair, aside from having Windows for work, they're also the only ones I know at this point who have a Windows computer at all.

I have a 1Password subscription but I find it too much of a hassle to use. Using the password manager is more cumbersome than resetting the password most of the time. And that obviously makes the password stored in the password manager out of date, making it even less useful.

For many logins I just use some re-used password with a prefix/suffix based on the service/site name, so I can usually get the password right without opening the manager or resetting the password.

I think most honest economists would tell you that economists have never been very good at predicting the future. They can do a pretty good job of explaining the why of the past and how markets work, but there are too many factors, either known or unknown that always come into play. But people really want predictions, which is why you get headlines like this one.
You can always post on your own thing and then syndicate it. It’s exactly what RSS was designed for after all.

I basically went the same way a few years ago. It's a shame that there are still gaps, and I understand why it doesn't work for everyone. But if you really enjoy using Linux or you're really sick of Windows and you're willing to try limiting yourself to Linux-compatible games, you will find that there are more games than you have time to play.

If you're willing to pair Linux with a gaming console, you get coverage that's more than good enough for me.

But only if the false positive rates are low enough, and/or the interventions required to follow up a false positive is small enough, and the benefit of earlier intervention in the case of true positives outweigh those risks.

Large scale testing is highly dicey and requires careful consideration because it often takes very low risks from false positives to outweigh the benefits.

I have issues with mainstream dev/IT world. Too much fad and money.. makes them think too high of themselves often. I kinda miss the people working in simple manual jobs (a lot actually). They're not perfect but it's easier not to be annoyed with people who didn't have college education and have to produce "more" with less on a daily basis. Also the amount of people that have allergies toward anybody that is not ready to master the web or apps is staggering some times.
This debate makes zero sense. You are both arguing where some extremely binary line is placed in society. If this how you all think about everything?
I think the like button is fine. There have been ways of expressing agreement or disagreement long before that idea came along. (See also: "This")

In my opinion, infinite scrolling is substantially more damaging. If you have poor self control, which I think many people do, using an app that does nothing to tell you when to quit is an open invitation to addiction.

You can believe that the world is flat, announce that boldly and stand by your statement. It doesn't mean it's true in reality, only that it's true in your mind.

Edit: This is more blunt than I intended it to be. For what it's worth, I happen to agree with you in principle, but I also think you're taking the roof off the car here and boldly claiming that the experience is so much better in the summer. What about winter? What about when it rains? What are the trade-offs? Not mentioning the downsides means that you either haven't found them, haven't thought about them or are intentionally omitting them from the discussion.
If you have access to an Apple developer account I would use the [WeatherKit REST API]. It's very similar to the Dark Sky API. (Presumably designed by the same devs). I'm going to ask one of my friends for an API key for their unused free quota.

OpenWeather's [One Call API] is almost a drop-in replacement for the DarkSky API. There are a few minor differences.

[Open-Meteo] is another really good API. Unfortunately it doesn't have the "minutely" forecast data, which I find really useful. (Is it going to start raining in the next few minutes? When will it stop?)

I see this a lot right here on hackernews. You could say as an aside "nobody likes getting kicked in the genitals" and you'll have some folks actually-ing about it obnoxiously -- and they'll ignore the real thread of conversation. There are also folks that can't or more likely choose not to understand hyperbole. It's exhausting.
