Ask HN: Coming back to Web/Ruby/Rails since 2012. Help?
I stopped working with Ruby/Rails in 2012. I think the last version I worked with was 3.1. Since then, I've been mostly focused on low-level things and C/C++. Getting back on the web horse now and I feel quite lost:

1) Is Rails still the best choice for a PIM-like web-based system?
2) Is Rails still popular and the defacto standard of the Ruby community?
3) What's the current best practice for running production? Passenger + Nginx?
Well, I'd go further, and propose to void all rules that mandate landscaping choices, which have non-trivial maintenance cost (rule of thumb: if you need to do gardening more than once a year, it's not negligible).

Or just have the rules convert to "must not look abandoned", as long as that doesn't conflict with other existing rules. In case of conflict, the "must be lawn" rule would just disappear with no replacement.
Yes. I am a big fan of corded electric lawn gear. Maybe it doesn't work if you have to mow an acerage, but for a normal suburban environment corded blowers, trimmers, and mowers are all totally reasonable to use. No batteries to worry about, powerful enough, never have to fill up gas, often lighter than other options.

There's still plenty of use cases for gas units but if we could get them banned from everywhere but rural areas it would be a good step in the right direction.

Some folks go too far and say "nobody should have a lawn!!!" but they clearly don't understand the zenlike experience of avoiding one's family, drinking cheap lager, listening to a podcast, and working the lawn in the sunshine for a couple hours on a Saturday morning. Kept me sane last year more than anything else did.
What have you tried? Here's some resources:

CO and CO2 are different things, it's worth noting.
You've defined what you think free speech isn't, but can you define what free speech is, in your opinion?
It's an interesting side effect of our need to have constant identifiers on everyone that legal name/gender changes are so complicated. It's certainly not the only reason, or even the biggest. But it does seem like our society is particularly hostile to people changing anything that can be used as a primary identifier.

You mention contact linking being a possible cause of advertisers figuring out your new address, but it also wouldn't surprise me if at some point during the legal process credit industries just got notified about it. Although if that was the case you'd think that advertisers would have had the courtesy to use your correct name when sending junk mail, so... shrug.

It's a weird system that is so ridiculously good at tracking people, but still messes up so many basic details.
After reading that review, I noticed how desperately the Uppers are enslaved to proving that they have nothing to prove.
Here is a lay explanation.

Light travels at different speeds in different substances. But it always takes a path that is locally fastest - meaning that any nearby path would be slower. (This is called the Fermat principle.)

You can see this principle at work when you put a stick into water. Because light travels more slowly in water, the light first heads mostly straight up, then bends when it hits the air. The result is that light does not travel a straight path to your eye. Which means that the part of the stick in the water looks like it is where the light comes out of the water, rather than where the stick is. As a result you can see the stick visibly bend.

Now what is happening here is that you have a layer of warm air over cold air. Light travels faster in warm air. (That is because as air warms it expands, making it less dense. Less dense means that there is less getting in the way of the light and it can move faster.) Therefore that fastest path is for the light to go up into the warm air, go along the warm air, and then dive back down to your eyes.

In many places you can see the reverse of this on hot days where hot ground makes for a hot air layer next to the ground. When the conditions are right the light from the sky can reach your eyes by skimming along the ground, and you get blue patches in the ground. In a desert this can look like water in the distance.
Why do you say they don't blow as well? I replaced my gas blower with an electric one a couple years back and it blows even better than my gas did. I also can't think of a technical reason why this would be the case so I'm curious what you mean by this.
Having integrated both... Okta is an awful product and Auth0 is an excellent product. Night and day difference in quality.
I talked to one of the founders several years ago.

An experienced programmer probably could but:

- writing an app doesn't mean it's a business

- Okta has thousands of partner integrations, with the development costs borne by the partners.

Fun fact: Okta, an auth database company, did not have a DBA until around 200 employees. Then they ran into technical issues and started interviewing for one, but nobody was qualified to do the interviews. (They do have a DBA team now.)
We are one of the few families in our neighborhood who still use rakes. Nearly everyone else hires landscaping crews who use the gas powered models. A few homeowners have electrics, which are quieter but take far longer to finish the job - sometimes hours.
Most gas-powered leaf blowers and trimmers have 2-cycle engines where you mix the oil and fuel together and pretty much directly exhaust the combustion. Can't be good to burn that stuff...
Nice launch.

Ok I get Texas but who is saying Florida will be the next SV? If anything, the market seems very disappointing here, given the states size.
This is all well and good, but i'd much prefer the city focus on things like cleaning up all the broken glass everywhere or addressing the unhoused issues before taking on such superfluous tasks.
Woman says she's on birth control, isn't, and gets pregnant. Was the man raped? Man says he's a millionaire, but isn't. Was the woman raped?
Note that while it's annoying, it's certainly an option to plug-in the leaf blowers.
Is that the same as a frother? I've seen a streamer use one on-stream a few times for making frothed chai tea, and it uses a magnetic coupler...
Yep. My town (Encinitas, ca) also did it a while back. It went into full effect the beginning of last year. I would say at best there is 50% compliance i.e. half the gardeners are using electric, the other half gas. On the other hand I do think I'm seeing more electric blowers now which are quieter.
I... did not know Chris Roberts was behind the WC series... It totally captivated me as a kid, but I sure as heck didn't know who was responsible for its creation. It just sort of existed as a different realm without much thought of the behind-the-scenes
Can these people you are talking about still sell their book, legally? Could they give the book to another person in exchange for money, right in front of a cop, and face no legal recourse? You're confusing the word "banning" with the word "inconvenience".
It's been updated since then at least - there's a note that the sidebar doesn't work sometimes (2018).
Houses are a small part of landscaping maintenance around a city. I bet there aren't as many outlets available as you think. You also have to deal with consumption and ownership of the outlet, how do you re-imburse someone with external outlets in a townhouse situation?
At some point, if it's successful, there will be pressure to make something like this illegal - heck, in many countries it's probably already illegal.
The answer will be the same as asking the question, “who is responsible for an accident when the driver was using electronic steering?”.

Of course L3 and electronic steering are leagues apart when it comes to how much control they actually have on driving, but this is a difference of degree, not of kind.

As long as car makers allow the driver to intervene at any moment, I can’t picture a scenario where the system is held responsible in the event of accident.

What might happen(and Tesla insurance is headed in this direction), is that car manufacturers will profile drivers and offer “safe” drivers a deal where accidents are covered under warranty.

> Do you believe that someone should never be able to hold a job again because they donated money to a politician that an employee finds unsavory?

You have changed the goalposts, because 1) "someone" is a much broader category than CEO, and 2) "an employee" is much narrower than "many employees, a board member, and external supporters."

> I like the idea of due process

Due process has never applied to employment positions. Ever.

> There is no proof he acted against the interests of LGBT employees at Mozilla

You mean against their employment interest. He did help fund opposition to their personal interests.

> We can't force them all to be jobless homeless. That's totalitarian.

Funny thing is, Eich is neither jobless nor homeless, and people still hear about him. Wikipedia summarizes his few on masks, for example, and his work on Brave regularly appears on HN.

John Stuart Mill described it much better than I in "On Liberty":

"""We have a right, also, in various ways, to act upon our unfavourable opinion of any one, not to the oppression of his individuality, but in the exercise of ours. We are not bound, for example, to seek his society; we have a right to avoid it (though not to parade the avoidance), for we have a right to choose the society most acceptable to us. We have a right, and it may be our duty, to caution others against him, if we think his example or conversation likely to have a pernicious effect on those with whom he associates. We may give others a preference over him in optional good offices, except those which tend to his improvement. In these various modes a person may suffer very severe penalties at the hands of others, for faults which directly concern only himself; but he suffers these penalties only in so far as they are the natural, and, as it were, the spontaneous consequences of the faults themselves, not because they are purposely inflicted on him for the sake of punishment. """

> an employees personal feelings

Multiple employees, and volunteers. And at least one board member.

Certainly personal feelings are important. People are turned down all the time for a position because of "bad culture fit" or "rubs me wrong" or any number of personal reasons.

The fact and reality is that we are all emotional creatures. You cannot separate them.

But now that we're well off track - what does "cancel" mean?

Because I've looked and looked, and never found a definition which fits better than "rich, powerful, or famous people facing unwanted negative consequences of actions or expressions that liberals disagree with"?
Honest question: If you are backed by YC, it means you got some money, so why you don't spend more on design?

The design looks a little bit basic, and the animated boxes are annoying. Sorry for the negative feedback.
I like the ones needing outside forces much better.
This is absolutely /rife/ in my experience.
Risk of disease spread. Many outbreaks (mad cow, etc) were larger problems than they should have been because cattle from various farms had been mixed.

It also complicates source tracing for any other problem - bad feed, importing rules, etc.
Apropos to nothing, 7000 is also the number of platforms Doom runs on.
Buying solar or wind gets you about 3x the capacity for the same price in about 6-12 months. It's a lot cheaper and a lot less risk. And that's excluding operational cost. If you want capacity on a budget in a hurry, wind is your best bet right now. Nuclear is for the opposite scenario where you have decades time and are not in a hurry to get capacity online and don't mind paying an order of magnitude more.

The Chinese hedged their bets a few decades ago and wind + solar won there as well. China is breaking records in terms of growth of their renewable capacity and are a key technology supplier in that space and also a big part of why it got so cheap.
The higher the sound frequency, the easier it is to muffle it.
For some reason many programmers love to hate technologies that are old.

Hate floats, love big decimals

Hate OOP, love functional

Hate RDBMS, love nosql

Hate html web pages, love SPA

In my opinion it's a confluence of influences.

1) the same social media attitudes poisoning society generally. "I've got an opinion, and it's worth just as much as yours". News flash - opinions are like arseholes, everyone has one.

2) Inexperience - devs who have only ever built chat apps and don't understand why relationships hence RDBMS are common and useful in line of business applications. Devs who have not tried to capture the water level in a tank or the voltage from a solar panel and don't get why floats are useful.

3) resume padding. nuff said
Coworkers seeing the highly personal ads for something you'd prefer to be private?

All you have to do is go to the wrong page and a day later you have ads for things you have no interest in. It happens with HN, where I click a post and then see ads I'd rather not.

And then consider what needs to happen in order to target someone so personally or individually.

---

Question to someone in ad tech, do your customers lose greater than or less than 50% of their ad spend to targeting the wrong person, malicious bot nets used to syphon from the system, and / or other sources of loss?
I'm in the same camp because a lot of devs that say they have Linux support don't always support it well.
I think the article kind of fails to capture how amazing the game was when it came out. Amazing, as in jaw-dropping. There was nothing like that at the time with the same kind of production values: it was certainly an expensive game to make, and it showed in every aspect of it. It was also the first game to use SVGA which was a revolution in itself in VGA land. I still have fond memories of WC3, and I don't think it has aged that badly at all, compared to many other games that came out around the same time.
I wrangle a cord. It's honestly not that bad at all. A couple techniques like tying cords together help a lot. It's honestly not a big hassle; and if the law mandates it, then all of these businesses will adapt.

Considering they were not that popular to begin with, it seems like only a few thousand Americans would really be without access.

For what it's worth, the 2008 article OP references specifically mentions technology to significantly reduce the pollution from 2 stroke engines. This technology has since been widely adopted in the scooter industry. Modern scooters pollute less per mile than the average single occupant car.

Am I missing something here?

Choose any infinite sequence of binary numbers {0,1,0,0,...} and map the natural numbers to it. For any number not divisible by 2 or 3, go left if it maps to 0 and right if it maps to 1.

Doesn't this property still hold? That is, it's nothing to do with prime numbers and something to do with the quotient of {2,3}.
Check out the books 'The back of the napkin' and 'unfolding the napkin' by Dan Roam.
Profile photo with a person wearing a baseball cap and Oakleys? Yup, that’s a republican.
The IC engines used for lawn tools have significant weight and cost constraints and less regulation compared to the IC engines used in transportation which makes them much more polluting. Similarly, motorcycle engines are more polluting than car engines by an order of magnitude.
That high-frequency sound doesn't carry as far, at least
My apt complex has 'landscapers' that use these. Landscapers in quotes because there's about 10 sq meters of lawn and a few plants. Every weekend they're out there blowing dirt around. It's not like it does anything besides making the pool unusable.
FLOW is pretty much designed for this and used by NBA Top Shot.
The two stroke engines they use are terrible. I mean you mix oil into the fuel so it just burns off. No surprise that it's polluting disproportionately.
"Commonwealth Fusion Systems announced today that later this year it will start to build its first test reactor, dubbed SPARC, in a new facility in Devens, Massachusetts, not far from its current base in Cambridge. The company says the reactor, which would be the first in the world to produce more energy than is needed to run the reaction, could fire up as soon as 2025."

The key takeaway, for those skimming.
Is the threat of overnight destruction for many small businesses a reasonable way to approach this problem? I can easily imagine that not a single person passing this change ever thought about that.

Whether it is virtue points or an important issue is irrelevant, the way it was handled was appalling and harmful.

EDIT - If you're downvoting consider this: If you and your family were running a small landscaping business and need to replace thousands of dollars of equipment, you might feel differently. Be empathetic towards those people and consider other ways to accomplish the goal. We could just as easily have banned the sale of these after a future date. There are always options to mitigate the pressure on the affected persons.
What makes you think your hiring manager isn't already doing that based on their interaction with you and your looks? Even simply subconsciously?
cool-retro-term is fab for this.

It takes me back to the Amstrad PCW8256 that I used as a kid.

Those double sided CF2 disks were a better disk than either the 5.25" or the 3.5" IMHO.
This was a masterclass. Thank you so much.
In most cities there are electrical outlets for municipal workers too (in urban context they are often protected by a lock).

In many cases there is also a way to plug to the grid using traps on the side of streetlights.
Not Nonsense at all.

Cash is an abstraction of product so let's talk in terms of trading the product that the USD and GBP actually represents.

The "products" that were traded in your example above represents an exchange in energy because all products must be created from energy. Entropy is removed from raw materials and transferred to energy increasing the entropy of the energy and decreasing the entropy of the raw materials into usable product.

High entropy energy is unusable.

Usable Energy is therefore limited and as a result in order for those products to even exist usable energy must be sourced from a limited supply.

When you take from a limited supply someone else loses. Hence zero sum.

Even utility costs energy no matter how much you try to inflate it's worth with your imagination. You have much more "utility" living in a high energy economy then you do in say a human powered tribal economy in the amazon rain forest.
Or the commercial model that identifies criminals from their photograph. Turns out people who frown are criminals. People who smile aren't. Or so you'd believe if you anchored your expectations comparing mug shots to social media profile pictures.
Cursed indeed. I am enjoying the web 1.0 insanity of the Atari parts maker for 8-bit machines. Somewhere there is a person still making a bit of cash from 1985 tech.

You could probably make money on Shibboleth consulting.
Corded string trimmers and lawn mowers last forever but they never took off because wrangling cords sucks.
This is simply to make people feel good. Easier to tackle issues like this than to actually invest in solving real problems.
Wing Commander II is quite memorable to me because as a child I could never get it to work properly and it introduced me to the world of autoexec.bat and HIMEM.SYS. No matter what I did, I could never get both the in-game speech and the mouse working at the same time, it was either one or the other.
For houses, most usually do have access to an electric outlet. I have like 5 around my house on the exterior.
Yes that's basically what I wrote about here:

I listed 3 or 4 caveats. CDATA might be another one since I'm not handling those... I've never used it so I left it out.

Actually I remember that regular languages weren't entirely enough; I think the .*? non-greedy matching was useful, e.g. for finding --> at the end of comments.
> Data poisoning, which involves contributing meaningless or harmful data. AdNauseam, for example, is a browser extension that clicks on every single ad served to you, thus confusing Google’s ad-targeting algorithms.

Wait a minute, if every ad is clicked on won't that give an enormous amount of money to the companies that created the problem in the first place?
There's something very Terry Pratchett about this - and there's some truth to it, too.

I think we can reduce it to "be willing to take risks but don't be insanely stupid."

Which doesn't sound as amazing, to be honest.
Oh my goodness. The actual people doing the work are not labeled on that diagram. It's just an anonymous icon of heads. If that doesn't tell you everything...
That isn't true any more.

Comparing the commercial EGO systems to the commercial Husqvarna systems, both produce ~600cfm of air movement in a backpack system. The battery life on the EGO systems is sufficient (60 min+ runtime peer battery, in my experience, more than enough for several large yards during mowing season).

Yes, a landscape crew would need to carry several spare batteries per electric device, likely with some sort of charging station on the truck. Expensive up front costs, no question. But, probably worth it in the long run for emissions and nuisance gains.
Your banal misinterpretation of my ideas is more applicable to your own trite comments than my own.

If you think taxing zombie landowners and forcing a more equitable evolution in the archaic property market is too extreme wait until you hear some other ideas like:

Nationwide rent and mortgage strikes

Renters unions

Actually collectizing housing by taking property, some people aren't even ashamed to say they'd be forceful about it if their positions continue to deteriorate.

We can keep debating solutions to these problems until the worst effected take matters into their own hands, and pay more to clean up the mess, or we can behave like rational humans and make sure that everyone has the basic necessities of life as a prophylactic against mob violence from those with nothing to lost but their miserable lives.

So please, take a stand and share with us what your solutions are and how you're so confident they're better than the ones I've mentioned. Casually calling ideas extreme and unserious without honest consideration is at minimum rude and at worse a disingenuous bad faith distraction from the merits of my statement.
>Show me someone who works as a professional video editor who does it on a laptop screen.

I know a videographer who worked for news wire services who did just this and did his job on a MacBook sometimes on site. Helped him deliver news content faster. I don't think video editing on a MBP directly is as rare as you might assume.

No doubt that Mac's haven't turnee into ideal gaming machines, but I've gamed on ultraportables with a lot less GPU than this, I just never played a game like Tomb Raider.
Yep. That new Ford with the big inverter and battery will be a good model to follow; and of course no doubt companies like Milwaukee who have been pushing all sorts of electric stuff lately will come out with good options to add on.

Hell, even just running a 4-stroke generator will be far less polluting.
They need to outlaw trimming, that's killing photosynthesis providing life that takes carbon out of the air.
