It’s not like the electric ones are significantly quieter for any given amount of power. Moving the air is most of the noise.

The electric ones might be slightly quieter (due to having less power), but then the trade off is running for longer because they have less power.
What does a guy have to do to get a jaywalking ticket in this town? (2017)
A little oral airline history — I was a student at Washington University in St. Louis in 2002 and 2003, studying EE and CS. I struggled, not with the material, but with my own personal issues and the fact that my girlfriend was 600 miles away in Minnesota. I dropped out of school and took a job at US Airways as a baggage handler so that I could fly for free. I learned SABRE fast, and wrote a little web app in PHP to help me memorize airport codes. (AVP = Scranton Wilkes Barre. Fifty years from now, this might be my dying thought.)

A year and two promotions later, I had dropped out and transferred "upstairs" to a generalist customer service job. I moved to Minneapolis, just an hour from my girlfriend, and worked as a ticket agent, gate agent, and baggage service agent. At that point I knew five distinct SABRE subsystems very well. Ticketing, gate, baggage, ramp (DECS), and flight operations (also DECS) are all handled differently in SABRE. I learned intuitively how VCRs work and could "pull" them out of defunct reservations and "push" them onto new ones, which made me the fastest re-booker at the station. I could sell a Zed fare in 30 seconds, and almost never needed to hand over a paper ticket to a customer, which meant that my end of day report was usually clean. In retrospect, SABREs green screen commands formed kind of a functional language in a real-time Vim-like environment.

I was laid off from US Airways in the wake of its America West reverse merger. I took a job with Carlson Wagonlit as a corporate travel agent. Carlson used a complicated mid-2000s web app instead of SABRE or Amadeus, and ultimately I was able to automate a large part of my job with an HTA application (JavaScript with system privileges on Windows NT). After I showed my work to our IT department at the insistence of my supervisor, who thought I was breaking the rules, a mid-career developer took me aside and gave me stern advice to leave Carlson immediately and seek employment as a programmer. I had no idea that software skills were worth anything, and quintupled my income overnight.

Fifteen years later, I remember the feeling of throwing bags onto conveyor belts like it was yesterday. I loved that job, and I loved SABRE.

It's a willpower issue for 3 days, the time it takes for your stomach and appetite to readjust to a lower volume of food intake. Anyone who's fasted knows how easy skipping meals is--it's certainly not the agonizing test of willpower you and many nonfasters seem to think it is.

And by the way, if diet and exercise are not the path to weight loss, then what is?
I'm sure nothing bad will happen to our nuclear waste in the next 500 millions years.
Yup. This article is neither new nor neutral.
“To equal the hydrocarbon emissions of about a half-hour of yard work with this two-stroke leaf blower, you'd have to drive a Ford Raptor for 3,887 miles, or the distance from Northern Texas to Anchorage, Alaska.”

While I agree with the authors opinion, I actually agree with you too, and quite like how succinctly you pointed out their hypocrisy. I personally didn't see it immediately.

Regardless, allow me to answer your question to perhaps give you a different perspective on the matter.

>Who are the people these two chaps see as being hurt by MIT's so-called "wokeness"? I.e., whom are they trying to help with their withdrawal of funds?

They probably see minorities from the Asian community who are hurt terribly from what I can only describe as incredibly racist policies wielded against them by the university. Also, members from poor white communities who also suffer because of these policies.

Furthermore, I think most people would agree the great things Western civilization has achieved over the centuries mostly comes from our respect for free speech and free thought, and the universities have traditionally been the institutions that took the lead roll in this. What will happen when the universities stop being the leaders of free thought? What institutions will take their place? It is not so far fetched to say that everyone on the planet could suffer from this

>Who are the people MIT sees as behind hurt by the people they stopped working with? I.e. whom is MIT trying to help with their options?

I honestly don't know. They clearly aren't trying to help people from disadvantaged communities, because they actively refuse to take into account objective measures such as family income when choosing applicants. I made another comment about this which I will just link to to save space: https://news.ycombinator.com/item?id=29135126.

Given that in the USA, Asians, Indians, and Nigerians all have a higher average family income that white people, it is clear that ones skin color has nothing to do with ones advantages: https://en.wikipedia.org/wiki/List_of_ethnic_groups_in_the_U.... What is clear is that ones background determines ones advantages. MIT is clearly making no effort to address these disadvantages, so what are they trying to do? My comment I linked to makes my opinion on that clear.
Surely the actual combustion is a large contribution to the noise? Especially for a smaller device with less insulation
> if that was truly the case, then wouldn't battery powered equipment have won the market already?

That's always the risk of arguing that it's in people's interests to already be doing something!

NYC apartments are nearly twice as large on average compared to Tokyo. In NYC bars and restaurants appear small to outsiders but go to Tokyo and wow, spaces are really small. That’s also a big part of its charm to be. But I couldn’t live like that day to day.
Electric versions of lawn tools are much quieter. I switched to a battery powered lawn mower this year, and it barely makes more noise than a box fan you'd put in a window. With my old gas mower that was a similar size, I had to wear hearing protection over top of ear buds just to be able to hear any music.
Try getting maple seeds (the helicopters) or pine needles off 2-8 week old grass seedlings with a rake (to prevent the grass seedlings from being smothered).

Gas blowers make light work of heavy, wet leaves. It’s why the landscapers use them rather than electrics.
They shouldn't ban generators in particular, because those enable people to buy all the other electric devices regardless of whether the power grid is reliable.
I play Rammstein's Du hast during takeoff to make it feel badass instead of scary, while also playing 2048 on my phone to keep my brain distracted. Noise cancelling earbuds help too.
The general idea came to me when discussing equal pay for women and how kids affects a women's career.

Thinking about ways to equalize education with kids frim different economic level. I came upon this idea.

There are many benefits and many drawbacks. No matter how taboo this topic it feels like the natural evolution of putting the children first, equalizing poverty backgrounds, equalizing pay, increasing workforce durations, spending power.

Why would you allow untrained professionals to raise our most valuable resource?
My impression (from being a teen at the time) is that this was still true at least until sometime in the 2000s.
Plug-in gardening equiment also exists, along with extension cords that should work with a yard of that size.

> Is it possible that they were servants and not slaves?

Fun Fact: This interpretive problem comes up in translations of the New Testament, where the same word is very frequently used in the context of [servant|slave] of [Christ|God]. See different translations of Romans 1:1.

The Greek word, δοῦλος (doulos) literally means "slave", and is a reference to the contemporaneous Roman practice as can also be seen in other Roman works written in Greek.

But this then creates all sorts of translation issues for English readers:

* if you use the word "slave", then people think of slavery of Africans (people chained, working in fields, being constantly whipped, living in large group quarters). This is way too harsh. The key point of doulos is that he was forced to do something by another will. The emphasis is on the powerless and passive nature of the slave, not on harsh treatment. A slave might be treated well, but if he was, it was only because his Lord decided to treat him that way. But in practice, they were household slaves with better treatment than African slaves.

* if you use the word "servant", then people perhaps think of a butler, which is way too soft. A Butler can decide to leave. He may not have the means to leave, but he has his own will.

So some translations use the term "bondservant" as a compromise, given the fact that this refers to something between our modern conception of slavery and our modern conception of servanthood.

Fun-Fact 2: One of the related words is diakoneo which means "to serve", so one "serves as a slave". From this we get the English word deacon, who is supposed to be a slave/servant of a local church, again with the ambiguity that this is between African slavery and being a butler.

Therefore if you really wanted to remain ambiguous (and mess with your readers) you could call them deacon's quarters.

From the Theological Dictionary of the New Testament entry for doulos[1]:

Hence we have a service which is not a matter of choice for the one who renders it, which he has to perform whether he likes or not, because he is subject as a slave to an alien will, to the will of his owner. → οἰκέτης is almost exactly synonymous, but in δοῦλος the stress is rather on the slave’s dependence on his lord, while οἰκέτης emphasises the position of the slave in relation to the world outside and in human society. This shows us again how strong is the passive element in δοῦλος, and in the whole word group to which it belongs.

While not terrible, that doesn't seem favorable for the gas leaf-blower. Most people use yard equipment once a week or more for that long during depending on season.

So using a leaf-blower for 30 mins once a week for 12 weeks has the same emissions as driving a extremely inefficient truck for 45k miles?
Note that this is true in terms of various pollutants, but importantly not CO2.
Another reason I'm glad not to live there. I like electric but this is impractically draconian.
You don't get to choose your public school's curriculum now.
My experience was that people follow the politeness “script” very well but don’t actually go out of their way to think of or help others. Part of it is there’s no cultural middle ground: either you’re ignoring someone or you’re going to work 90 hours a week to pay for their dialysis, nothing in between (okay, an exaggeration). It’s different. In the end, people are people so you can squeeze the toothpaste on one end, but it has to bulge out on the other to compensate.
> In no sane version of the world should "not adding a db index" lead to getting a 50x bill at the end of the month without knowing.

Oh, that would be actually quite useful for learning things if the bill would tell you that it got so high because you stupid dump-ass didn't use DB indices properly.

I'm every time shocked how many people using DBs don't know about indices! Those people should pay such a bill once. They would never ever again "forget" about DB indices I guess.

Of course I'm joking to some extend. But only to some extend…
You don't have a mental visualization of code execution? Quicksort, merge sort, binary search, hashmaps etc are just one image each, as easy to remember as the face of a friend. I don't see how anyone would forget that, there is no way I'll accidentally rearrange things to think the nose is above the eyes etc, and that is how stupid it looks when people make mistakes in coding interviews.
It is, but even without the engine, its still blowing air at high power. Picture a giant hair dryer, it's still super noisy.
The electric motors tend to be quieter and also weaker. But there are also newer models that are more powerful. And they do generate noise, but it sounds more like a hushed vacuum cleaner rather than the typical leaf-blower sound. If you want to hear the difference check out this particular timestamp of this comparison video (https://youtu.be/UUQeGzGy0Ds?t=397). The gas powered blower is ~5 dB louder at peak. The electric one is at 78 decibels peak (max power with "turbo") but the gas powered blower measures at 78 decibels just idling. The reviewer notes that the electric one is very bearable for him as an operator, but the gas powered one is too loud to think clearly.

That particular model of leaf blower with the backpack is fairly powerful, and the reviewer notes it pushes more air than the gas powered one he is using. However, a number of comments mention that the gas powered blower is much more powerful and that the reviewer is biased, which may be apparent from his early praise for the electric model.

The big issue is that the electric blower's runtime is limited. He gets 22 minutes out of a full battery using it "normally", which takes 1 hour 40 minutes to charge on the standard charger, and 42 minutes on the fast charger. He concludes that electric is better in every way for homeowners, and there's no reason to go back to gas unless you are a commercial user (presumably due to the battery limitations).
if you understand music the way you claim to you’re not a mediocre player, although you could be transitioning from ‘mediocre’ to ‘pretty good’

jazz is a personality thing. there are many great musicians who can’t stand jazz and don’t respect jazz players. i’m not saying that’s correct, i’m just saying that is. A range of opinions exist at all levels of the art, and since it’s art, the artists are right to have their opinions.

"Hey, Coal Miner" is a poignant glimpse into life in the mines. The whole song is great but this verse in particular always gets to me:

"Into the truck,
Then into the bath,
Ground to dust
And then in a flash,
Turns into fire
That turns into ash,
Hey, coal miner."

I'm glad you pointed that out! Where I'm from, we use "kahunas," not "cojones." But I'm glad to know that there's a regional difference.

Also, I don't think you should trust a copywriter who uses either of those words in your copy (regardless of where they're from).
What you describe isn't a spinlock then. It's a regular blocking IPC primitive with an optimization layer that can busy-wait a bit.

As the term is pervasively used in industry, "spinlocks" always imply locking against other physical hardware, and that can't be done without spinning (I mean, you could fall back to blocking, but then the blocking implementation in the kernel would have to lock its own data structures to effect the scheduling; it's a chicken and egg problem). They usually, but not quite always, imply protection against asynchronous interrupts or signals too.
Jaywalking tickets are very much a thing in Southern California, but you'll pretty much only get one if you're doing it in a blatantly unsafe manor.
You seem to be implying that E2E is impossible without client-side CSAM scanning, but this is obviously false since other companies offer E2E without that.
Everyone just buys them out of state. There’s literally an entire market for it now. And since most the people using them are immigrants no one is going to seriously back a law banning them from use unless they want to be a named racist. It’s all just a show.

What’s the limiting principle or boundary condition of “equal opportunity”? Is every social institution required to compensate for all external inequalities? If so, how can each institution subjectively compensate for social inequalities without diminishing their respective core functions?

The point here is that institutions must provide equal opportunity within their own functional scope. But simultaneously, institutions must also maintain enough filtering criteria to ensure they do not abandon their core function.

MIT best serves general social questions of equal opportunity by accepting individuals based on some standard quantifiable baseline filtering criteria, and tackling such vast social questions through open and honest inquiry & research.

As a side note, perhaps institutions that are closer to problems like social inequality are best suited to serve them.
There's more to vim keybindings and modal editing than "nav keys on home row". e.g. if the editor has the line `println("Hello |World")` where the cursor is at |, you can change the whole text inside the "" by typing `ci"`, or change the word by typing `cw`. -- QMK is great, but it can't do that.

I use Vim (and Emacs) as a Dvorak user. I don't change the layouts; I just stick with mnemonics. e.g. in vim, g is "go..", c is "change..", d is "delete..".
With Dvorak, the `jk` are adjacent, so that works out. `h` is still to the left of `l`... but, vim's keybindings are excellent at navigating in a line, so many `h`/`l` should be avoided anyway.

I think "hard to get vim to be as good a development environment as an IDE" is more/less a fair point.

Anyway, it's great that micro can fill a niche for you. I wish everyone could appreciate modal editing and symmetrical keyboards.
Same here - but years prior as I was remote then too. One particular lady, every day in the fall, would climb on a ladder and use a leaf blower to try to clean leaves from the gutters. Like, hours of leafblower a day. I'm not a violent person, but that noise was so aggravating I had daydreams of kicking that ladder over.

To this day, I don't understand why cities or neighborhoods don't at least limit the days they can be used. Everywhere I've lived, someone in earshot is mowing or blowing every...single...day.

I haven't seen it enforced in Germany and despite what OP said, you can see people crossing on red light in Germany too but people tend to have a greater awareness of car traffic here. You know the car driver don't expect you to cross when he's got green and the pedestrian knows that they may die because the driver doesn't expect him to cross.

It's different in Poland for example. If you don't just go on a pedestrian crossing (no lights), no car will stop. Because of that it's more likely for people to cross on a red light because they know car drivers are trained to watch out for them. A really bad development. People die because of this.

A very helpful campaign in Germany were signs which told you to be a good example for children. It grew into the consciousness of the population and you very rarely see people cross on red when there are kids around. Also having green on demand buttons which give you FAST results helps too. They are very popular in Germany now.
>EDIT: One feature I would love on HN is some way to add tags to posters that I see, so I could somehow mark the worst offenders in reality-denying and can make sure to disregard their opinions in other ways, because their brains obviously can process information correctly.

But why do you need a tagging system for that? If they're constantly spewing "reality-denying" comments then surely you can tell by the comments? Or do you find the tagging system useful for when they make plausibly sounding comments, so you can dismiss those with prejudice as well?
The structure of the city also makes it a great place to raise a family. That's why my family settled here. The kids have a safe, walkable community where almost everyone knows them and they feel at home and empowered. But we're also in a global center with great opportunities, jobs, school, etc.
I find this hard to believe. I remember mowing the lawn for my parents, powering my ridealong lawn mower with a few gallons of gas for an hour or two (or maybe 30 minutes, I don't remember how long it took me). My car, at best, would drive for an hour on a few gallons of gas. So about the same amount of time. What gives?

If you are hispanic could you help me with feedback about this landing page of our startup? (we started in Mexico but soon we will adapt the service to USA in English).

I've seen medieval beds in the UK that were a wooden 'tray' (on legs, or built into a wall) and the guides said a hessian bag was filled with straw (dried stems of wheat/corn/barley; straw and hay are often used interchangeably though, so it might have been dried wild grasses) for bedding.

I assumed poor people slept on the floor with whatever coverings they could muster. Suspended beds seem very decadent.

The stretched fabric, like canvas, over a rectangular frame design seems pretty common and would have surely been a more natural early bed. Similarly hammocks - which I thought were common on ships (at least in the later middle ages).

Guess I've discovered I'd like to read a history of beds!
Isn’t the price per square metre much lower in Tokyo though? I live in Tokyo and my place is much larger and nicer than what I could afford in my previous place, Vancouver.

And one nice thing about Tokyo is one can live in very small but clean and private apartments if needed. I’d take that over roommates and illegal basement suites.
