Battery life is going to be a very serious limiting factor. It's one thing to walk all day in a new city you are visiting, and think only about recharging yourself. But walking an hour in these, and then carry them (and they should be heavy, relatively speaking) until next charge - I think it would not be worth it.

Hi! Do you live in The Netherlands or somewhere else? If the former, I have a question, though I guess anywhere in Europe is probably close enough.

I just moved here from the US. I live in the Noord Brabant in NL and currently own a car. The village I live in does not have a train station, not to mention that it is pretty pricey to take the train to work, both in time and money. My commute costs about €15 per day on public transport and up to 2 hours each way. I also have family that live in Belgium, about 150km away, also in a small village with no train station. Driving makes a lot of sense for me currently.

Sorry, to the actual question. When you travel abroad, what is your cutoff for taking the train versus flying? From where I live to Brussels, it's about half the price to take the train versus flying, but go out a bit further to Paris, and it's about 25% cheaper to fly. If I'm in NL, it seems like it would almost always be more economical to fly if the destination is more than 300km away. These are also cursory Google searches so the timeline is 3-4 weeks out. When planning a trip months in advance, I would assume the flights and train tickets will be cheaper, but likely still comparable in terms of percentages.

My car is also very efficient. A full tank to drive 600km costs about €60. I realize I would need to pay for parking at the destination, but if I'm staying at a hotel or outside the city center, I think it would still be cheaper. Another cursory train search, Eindhoven to Prague is €140 per person round trip. Traveling alone, probably worth it, but with a family, driving seems more economical.

I feel a bit ramble-y but hopefully that makes sense. I'm trying to figure out how this whole "European" thing works :)
That is an advantage not a reason it can't be used.

Yes alternatives(8) points a symbolic link to a name in the alternatives directory, which means that when you custom package's link to /user/bin/python is overwritten it is trivial to restore.

A lot less fragile and resource intensive than using the audit system which the blog post clearly mentions is a bit crusty.

Apparmor is another method that is a bit less expensive if it is in use but obviously doesn't work for containers.
We know it's based on the meme. You're probably downvoted because it's played out and doesn't really apply to this specific post much.

You might find David Wright's presentations about Unreal 5 interesting:

https://highperformancegraphics.org/slides22/Journey_to_Nani...

https://advances.realtimerendering.com/s2022/index.html#Lume...

They're great presentations with a lot of depth in the notes. I think videos are around somewhere if you prefer that.

Two specifics I'd mention:

It seems a lot of games now use feedback between frames as a way to tolerate the latency of moving data between CPU and GPU. Eg the CPU will use GPU crunched data from the previous frame as a source for CPU crunching that optimizes what data gets passed to the GPU next.

The other is that fixed functionality is moving into shaders. Unreal 5 uses a mix of hardware rasterization and software rasterization in a shader (and path tracing now as well). There the tradeoff between the two is triangle size in pixels.

They also spent some effort marketing the DX4 as a low end alternative to the Pentium. It was possible to buy/build DX4 machines. Trouble there is the same as any other low end offering of the time - it got steamrolled by better technology coming down in price as quickly as it did. The window of opportunity for anything low end was not that large.

There is plenty of authoritative and arrogant attitude to go around. Our most precious resource these days is time. If it takes longer it is not acceptable.

Aesthetic taste and fashion are hard to predict; people said the same thing of Crocs. In fact, many workplaces banned Crocs because they were considered so aesthetically offensive. Crocs, Inc. is up 725% over its lifetime.

People are really into weird shoes right now (see pretty much all of sneakerhead culture). I could see this taking off if partnered with the right influencer and offered at about $500-$600.

380->340 over 6 months. I was off for 6 months and maintained 340 with diet changes and exercise. You cannot go back to the old diet and expect to maintain. I'm back on now to lose some more.

Some other things I've learned:

Take the first shot on an empty stomach. Expect the first 3 days to be rough. Hunger is more than one sensation, and when you have severe calorie deficit, your body will feel very bad (at least at first).

It is critical to control your food environment - don't bring junk food home, don't go to restaurants too often.

I learned to slow down and enjoy the food reward, instead of trying to chase it. No words will tell you how to do this for yourself.

There is a feeling that I call "future hunger", where I don't feel bad, but I feel like I will in a while. In the past, my body and mind would get frantic when I felt this way. Now I have a very small snack and ask myself "do you feel bad right now, or do you feel like you're going to feel bad". Again, these words may not translate.

More than one serving of salty and sugary snacks should NEVER be within arms reach, and preferably not in the same room. Your mind will remember these snacks and oftentimes eat them without conscious effort.
> we've been given the wrong advice for so long we just stopped listening.

Shouldn't we recognize that things change and life can be unpredictable? Rather than being jaded that every adult in our lives didn't have a magical crystal ball, maybe there are more productive things that can be done?

Gen Z & younger Millennials constantly get shit for blaming everyone else for everything always, and taking no responsibility or being accountable for their own actions...but I would argue that comments like the above aren't going to dispel that.

Maybe it reads different than it's intended, but a huge part of being an adult is adapting to an ever changing world and finding a path forward towards your goals.

(Edited to remove what could be perceived as a bit harsh..)
With almost any other project, I can take the source code, make some change, and then propose that the upstream project incorporates my change. If the upstream project thinks my code is good, they will incorporate it as-is.

With SQLite, that's just not a process. There is no process whereby code written by anyone other than the SQLite maintainers enters the git repository.
> Neither the FTC action nor state policies like those in California generally prohibit noncompetes while employed.

Where did you get that idea? In California: non-competes are carte blanche unenforced and even considered abusive and illegal in many contexts (for non-executives), whether you're currently employed or not.
I think the common usage is government agents, but more generally it is/was used to refer to things that instill fear or disgust. e.g. ghosts, the feds, and for racists, certain races. I would probably consider a branding update because the historical racial usage is probably enough to dwarf any positive discussion of the platform.

If there is a value implicit seeing to gather disconfirming evidence by asking the decision maker what would change their mind, it seems to me to be a commitment to the scientific method of allowing new data to overturn existing models and hypotheses.

My apologies if I imputed motives in your question that were not there.

What I meant by that is that laws and regulations still apply. Crypto exchanges are not exempt from society just because they are online.

<< You are wrong about "should", because the word can and does describe non-emotional states
>>
Questions of "how should a company behave?" can only be answered by one's feelings, and feelings require emotions to be formed. There are no rules of business encoded into the universe. Business itself is merely a human construct."

If that is the case, then everything is emotional. If everything is emotional, in practical sense, designation of 'emotional' does not carry using informational value. It is like calling everything racist.

<< At end the end of the day, if I need to make a call to the old country and various apps don't work for one reason or another
>>
The modern phone system is built on apps, so if apps are not working for one reason or another the app you call a phone isn't going to work anyway. Long gone are the days of an operator physically connecting copper wires between two locations. The phone system you seem to be imagining no longer exists outside of museums.

I would welcome some schooling on the matter. Do you have some additional insight/resources that could substantiate your claim? I do not exactly doubt you, but, just like with the underpinnings of US airlines, part of me sincerely doubts telecoms moved to, say, react framework to connect phonecalls. I might be wrong, but I would like some additional evidence of that.

<< And like I said in another comment, if you used papyrus to request support from your telecom operator, I expect you would receive even worse support than by phone. It's not where they are going to focus their energy because papyrus isn't where the community of customers live. I imagine they would put in some effort to accommodate you, but with only so much time in the day it will pale in comparison to where they put their focus.

I am not sure if you ever sent a complaint letter to a bank or similar regulated institution. I won't go into too many details, but, if anything, written letter gets a much closer scrutiny. It may be slower, but it does get results ( edit: speaking from experience ).

<< Like I said, it depends on the business.

I am willing to accept it as an argument.
Anecdotal HR story: I got hurt at work once and required surgery. I came into work with this information and told my friendly, cheerful HR person the news. They closed the door to their office and began visibly stressing out about the workers comp claim. I wasn't being berated, but I was being questioned on my motive behind going to a hospital instead of the assigned "occupational health specialist" that the company employed.

The HR person literally said, verbatim, "Awww why didn't you go to OUR doctors? You went to a hospital? This is going to cost us a fortune!"

That really put HR into perspective for me.

This. Americans are too used to owning a personal car and driving it even though short trips can be replaced by public transit.

I agree US is too big to be covered by public transit, but if we want to win the climate war, US has to cover all its states and make public transit seamless. Once this goal is complete, discourage owning of personal vehicle.

Also a picture comparing car vs bus [1]. Now compare the green house emission between two.

> The solution is really quiet simple, recharge the trucks and buy a few more to account for the fact that you have to recharge an hour for every 4 in operation. Stop trying to run your trucks for 12 hours straight.

I had to re-read this twice to make sure i wasnt misreading something.

The "simple" solution is to redesign the entire system, buy more vehicles, hire more drivers, etc because you are "pro electric" and electric vehicles cant perform the job?

Here's an idea.. Diesel vehicles are built to run 24 hours a day, and this is why they have large fuel tanks and heavy duty engines. Perhaps EV should be built to run 12 hours a day as well?

if the EV cant compete, then don't use it for this use case.

why should they "stop trying to run your trucks 12 hours a day" when they have done this for DECADES?

you make it sound like this 12 hour day is the problem, it is not, it is the EV's failure to keep up that is the issue.
> That said, when I lived in Chicago, I used to see a lady who rollerbladed to the office.

I used to skateboard from a lot by the Metra station to the office @ State and Madison.

Most fellow commuters I encountered were visibly bothered by sharing the walkways with someone adult-sized traveling 2-3X their speed. I'd expect a similar level of antisocial friction with these shoes.

Though it has been well over a decade since I did that, maybe people have since warmed up to sharing sidewalks with ebikes/scooters by now.

Perhaps, but it is unusual for humans to be aware that they're protected from such.
In a well-run company, HR stays in their lane and executes orders from management.

In all too many companies in the real world, management is a chaotic revolving door of political infighting, and HR has a great deal of power. I've worked in a team where an HR rep attended every personnel-related management meeting, and overruled performance ratings, promotions etc while the VP supposedly running the show played Candy Crush.
An emergency is a valid concern and I believe all cars, regardless of Tesla, that feature electronic (fancy) doors also feature physical escape latches. In the Model 3 you can pull up on a handle on the door to force the door open without the power required to first roll down the window to clear the weather seal this will also unlock the door as well.

From your own linked article:

> Juhta criticized the emergency protocol for Tesla’s electric cars, saying that it isn’t intuitive enough.

Which is kinda ironic to me considering anytime a new rider is in my car I make sure to tell them about pressing the small button to open the door because they seem to find that escape latch on their own and often think it's just a regular open door latch.
Show HN: Stoat – build previews and metrics in pull request comments
Hi HN!

We're Jared and Liren. We are building Stoat, which allows you to turn pull request comments into developer dashboards: https://stoat.dev/

Builds produce a bunch of useful information that's difficult to access on CI/CD platforms such as GitHub. Even accessing test results for your latest commit can take a minute or two. Code coverage reports may be available in logs (which are hard to search through) or not at all. Generated docs and other reports are usually omitted from builds. Stoat takes any type of file (static sites, code coverage reports, images, etc) at the end of each build, hosts them, and links to them in a single PR comment.

Builds also can produce a lot of metrics such as build runtimes, benchmarks, and some business KPIs. These metrics are usually ignored or pushed to something like Datadog and checked reactively after the changes are merged or deployed. For example, there usually isn't an easy way to compare the current PR's impact on build times before merging. Stoat makes it easy to generate and embed charts directly in PR comments so it's easy to compare metrics generated by builds from different branches. If you're increasing the build time 30%, it should be noticeable!

To solve these problems Stoat runs in three steps:

1. We consume GitHub build outputs (using an action)

2. We process/aggregate/host these outputs

3. We render this data into a single, templatable PR comment (similar to https://github.com/peter-evans/create-or-update-comment but we aggregate data across build runs using state stored on an external server to avoid race conditions)

Here are some example PRs using Stoat:

- Tracking build runtimes: https://github.com/stoat-dev/stoat-action/pull/101

- Previewing a variety of build outputs: https://github.com/stoat-dev/example-java/pull/1

- Previewing gifs and videos: https://github.com/stoat-dev/example-remotion/pull/2

Here’s a 4-minute demo video: https://youtu.be/oikep47_7ro

In the near future we're planning on adding more tools so users can compare versions of images and files generated by builds (but not checked in), track custom metrics, track integration tests, and more! Longer term, we're aiming to be a platform for DevTools/DevEx teams building out these types of tools internally. We'll have paid plans for private repo support and some advanced features, but our basic features will always be free for public repos.

Give it a spin on one of your public repos at https://github.com/stoat-dev/stoat-action#quick-start or check out our docs at https://docs.stoat.dev/

Let us know what you think! Thanks!
