Acidity will increase if there is more carbon. Ocean acidity is believed to be behind the greatest marine extinction we know about. 90% extinction iirc.
I think about this all the time:

Would it be possible to change the anti-trust laws so that companies can not merge or be acquired if the sum of their assets and revenue exceeds a set dollar figure adjusted for inflation?

If A(assets + revenue) + B(assets + revenue) >= $, then not allowed to merge.

This will promote competition from upstarts and increase the efficiency of these companies by preventing them from gobbling up every new market.
I retired my G4-based Mac from everyday use in 2009. I don't recall having major issues. But I suppose it depended on what you were doing. I was doing mostly web, Java, Python at the time.

There are plenty of ways to get to your home directory in Finder that are easier than opening Terminal:

- If this is where you most commonly want to get to, Finder => Preferences… => General => New Finder windows show <home directory>. All new Finder windows will open there automatically from now on.

- If you leave the above setting on its default, new Finder windows open ~/Documents. Hit ⌘↑. Or if you have the path bar switched on (View => Show Path Bar), double-click your home directory in the path bar.

- Drag it into the sidebar or go to Finder => Preferences… => Sidebar and tick your home directory.

- Drag it into the dock.
Jira was a complete nightmare at my last position. I am still convinced it was the PM's poor implementation so they would have the box pushing job. Everything was customized and it took me weeks to learn the workflow.

> This guy says you can build high-performance acoustic panels with old towels.

Towels, acoustic panels and other materials are good at reducing echos but it doesn't really do much at all for reducing the amount of sound that can enter or escape a room.

If you had an open room with a hardwood floor, you'd likely get a lot of echos when talking normally. That's where things like acoustic panels help out.

If you want to dampen the noise of your neighbor's kids screaming like maniacs you'd have to do a pretty serious amount of sound proofing with other strategies. It's a lot more complicated.

From the point of UI / UX, I cannot think of a worse software than Skype (all platforms including Android).

It's always a hard struggle, effort and suffering to make a call to a phone number, even if this phone number is in the contacts of the phone, or has been called before.

Adding to that, when Microsoft acquired Skype, they were offering to merge the Skype and Live accounts, which I agreed to, which rendered my Skype account unusable (with credit on it and lot of contacts registered).

The. Worst.

This is a really in depth read about OO design patterns in the Linux Kernel using C: https://lwn.net/Articles/444910/

The easiest to understand example (for me) is that you can manually implement polymorphism support using function pointers that take in a struct instance as an argument. Polymorphism is fundamentally just a method call that's dependent on which target object it's being called on, so this pattern allows you to pass in the target object (as a struct since it's C) explicitly.

From the article:

> Some simple examples of this in the Linux kernel are the file_lock_operations structure which contains two function pointers each of which take a pointer to a struct file_lock, and the seq_operations vtable which contains four function pointers which each operate on a struct seq_file.
It's simplistic. When you move into distributed systems, these claims are not sufficient to indicate "so we're fine". Even with the ACID, the "I" has multiple levels, and often they get things wrong (see Jepsen).

Small naturally aspirated gasoline engines are also quieter than turbodiesels. With some good noise dampening in the engine compartment and exhaust system some cars are surprisingly quiet even at low speeds. Also, some roads are louder than others (cobblestone being very loud regardless of speed).
Yeah, and it shouldn't be too hard to hook up existing nightly Rust to use the Kernel's panic functionality; it already supports user-overridable panics for no_std, iirc
Sound decays exponentially as a function of distance, so speakers close to you don't need to be loud. Also most speakers are also fairly directional, so i'd expect any extra energy to be absorbed by the room (as heat).

Edit: more importantly these are destructive waves, so if anything you’d actually reduce reflections back out into the world.
I expect a hefty number of people would be willing to undergo controlled variolation for covid, where they'd be of no risk to others.

Nice job! Two clicks on my phone and first route was spot on.
We're warming about 0.2C per decade. So, even assuming that accelerates we're going from a current 1 C change since per-industrial times to 2 C change in average temperatures. I'm going to call that a little compared to what's coming over the next couple centuries.
I hear about the supposed selective targeting of conservatives all the time, but don't really see any evidence for it. Every well known conservative has a huge following on Twitter or YouTube. People sometimes point to Alex Jones as an example but he was clearly banned for smearing the parents of murdered Newtown children. I'm not saying that big tech doesn't lean left, but I don't see evidence that they target people just for being conservative.
Apple Music. Trying to make it play something on a HomePod from iOS takes a computer science degree.
I agree that W10 is garbage, at least oob. I have found that there are tweaks you can do to make it better.

> the "File" menu in Microsoft Word opens across the whole screen with most of it being empty space,

Is this not to do with the version of word? My schools win 7 computers had this as well.

> the start menu fucking shows ads

I don't remember how I turned it off, but none of the win 10 computers I use show adds in the start menu. (They still do in solitaire though).

> search can't help itself but do random internet searches.

Yup, that's annoying as all get out.

> Always on "Cortana"

I think there's a way to turn off Cortana being used constantly, I don't know if it actually stops it in the background though.

> On top of that, it's basically spyware.

Yup. I only use it for games for this very reason.

...

What it comes down to is what you're willing to deal with. I'd rather risk M$ spying on my games then some (slightly) less ethical attacker getting a foothold onto my network.

I find civil engineering is often quite interesting, because the tradeoffs and issues can be surprisingly inobvious.
The biggest factor is randomness, which can't be understood in that way. People frequently imagine stories about why HN is "doing" this or that, but that's a category error, since HN is a statistical cloud. Randomness plus cognitive bias equals narrative, etc.

You'll notice that your GP comment is now upvoted while this one is downvoted. That's common, because unfairly downvoted comments frequently get corrective upvotes from users who come along and see that the comment is fine: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que.... Meanwhile, complaints like this one break the site guidelines (see https://news.ycombinator.com/newsguidelines.html at the bottom!) and usually end up being false as well.

Agree, even then hopefully better home battery storage removes the need for any fossil fuel based engine at all.
Quick anecdote... It defaulted to metric units globally when I first launched it ~8 months ago. But that quickly resulted in complaints from North American users, so it now defaults to imperial units in North America and metric everywhere else. Users can change it in the settings menu, of course.

Thanks for the kind words!
ConsoleZ on Windows that I use with Cygwin, being on one hand the best terminal app for Windows, on the other there were things that were driving me insane. The main project seems to be sort of abandoned, so I eventually fixed them myself[1].

Strongly agree about this. Docker is conceptually on the right track, but it's fundamentally the wrong abstraction.

If a specific person's respiratory system is really so bad that a mask would have a significant, deleterious effect, then a mask ordinance is of no consequence because that person really should not even be going out in public at all during the pandemic.
Sadly, this is a bit difficult to do on iOS.
If you are building stuff on Apple ecosystem and you can wait, better to go for ARM.

Otherwise, why do you want to wait? I don't think Apple is going to drop Intel support anytime soon.
That's the thing, it is useful, so I don't blame companies for wanting people who know CS theory.

And when I hire people, even though I hate doing adversarial whiteboard coding, I will probe to find out if people understand a bit of theory.

You can get a lot of work done without theoretical knowledge, (but the end result is often not as good, and it usually takes longer). Combine that with the fact that CS theory is hard, and you get a lot of people complaining about how theoretical CS is useless outside of academia.

It's basically an extension of "no one needs to know math beyond arithmetic in the real world".

How is the 'write a byte to disk' loop faster than the empty loop? Maybe xrange() is dominating in the empty loop example.
Great idea! However, I found the hash part a bit confusing; why not use hashes per seconds or bytes per second for both of them?

Good enough reason is subjective, if someone says they don't like mask because its uncomfortable, its obviously significant enough reason for them.
Boggles my mind that somebody would buy a tool that would require familiarising themselves with reverse engineering tools. I mean how ridiculous a product is that ?
For me one of the worst were Docker for Desktop on both Mac and Windows, especially when used for local Kubernetes. I fixed this with a project running Kubernetes directly on a local virtual machine(s) and local Docker (without polluting the machine with Docker for Desktop) is a bonus that comes with that[1].

I maintain an open source ML infra project, where we've spent a ton of time on cost optimization for running GPU-intensive ML models, specifically on AWS: https://github.com/cortexlabs/cortex

If you've done zero optimization so far, there is likely some real low-hanging fruit:

1. If GPU instances are running up a huge EC2 bill, switch to spot instances (a g4dn.xlarge spot is $0.1578/hr in US West (Oregon) vs $0.526/hr on demand).

2. If inference costs are high, look into Inferentia ( https://docs.cortex.dev/deployments/inferentia ). For certain models, we've benchmarked over 4x improvements in efficiency. Additionally, autoscaling more conservatively and leveraging batch prediction wherever possible can make a real dent.

3. Finally, and likely the lowest hanging fruit of all, talk to your AWS rep. If your situation is dire, there's a very good chance they'll throw some credits your way while you figure things out.

If you're interested in trying Cortex out, AI Dungeon wrote a piece on how they used it to bring their spend down ~90%. For context, they serve a 5 GB GPT-2 model to thousands of players every day: https://medium.com/@aidungeon/how-we-scaled-ai-dungeon-2-to-...
Yes, and since the eighties the American Left embraced neoliberalism whole heatedly. Then leaned into progressiveness inorder to differentiate itself.

So yeah, now we have flavors of neoliberalism.
There's plenty of criticism of those topics. I think you're running into the notice-dislike bias: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que.... Your comment here mostly says how you feel about them.

This comment breaks the site guideline against going on about downvotes, by the way—in spirit if not in letter. Please don't post like this; it's off topic and boring.
Then Its for them to decide that. They may very well knew and accept the what you called "deleterious" effect.
Everyone one of these cloud storage services (Dropbox, Box, Drive, iCloud, S3, OneDrive) has adopted the same mental model of file storage that computer systems from the 80s devised to mimic filing cabinets. Namely: folders. I think a folder hierarchy has some value but they should really all be using a tagging system instead. Orgs tend to have multiple hierarchies based or org charts, projects, disciplines, timelines. Being able to tag documents across all or multiple would make browsing to the right document less of a maze. And make search more accurate.
gmail, by so many orders of magnitude.. Email interface designed by people who seemingly have never tried to read email.

Threading is completely broken, filtering is broken, compose screen is unusable.

At previous companies I've had to use gmail but was able to use a sane email client via IMAP so it was almost ok (although still somewhat broken as gmail doesn't handle IMAP correctly). At current work they disable all access except via the unusable gmail web interface. So definitely gmail is the worst I have to put up with everyday.

jira would be a distant second, but no comparison.
My apologies for not realizing that point you were making. I agree that it might be difficult to find a company that wants you to build their product using your OS project. I meant that there are probably companies out there that would evaluate your abilities on the strength of your OS project and then hire you to build whatever it was they needed.

If you want to make your side project your day job, that's a different story, but maybe it would be possible to build a startup on it. Easy to say, I know. The internet is full of well-meaning but effectively useless advice like mine. :)
Never Split the Difference is one of my favorite books.

There's a section in there about being right that basically sums it up as "always be worried when someone says 'you're right' as can mean they just want you to stop talking".

You probably want it to be something along the lines of "that's right" since it implies they also think that's the right outcome regardless of whether it's your or their idea.
this is AMAZING! very fast and planned some interesting routes in Portland that I hadn't thought of. I think i'll start using this over my premium strava route planner
This is really well done, congrats. I love the level of automation to make it so easy to use. Also the attention to UX, not just in the narrow UI sense but the actual experience of the trail.

Some thoughts:
- Create a community out of it so that people can rate the routes, and therefore provide feedback for the algo?
- Use some google streetview or alternative for landmarks along the way so people remember what they should be seeing and don't get lost?
JIRA is heavyweight, but I've never been remotely satisfied with any of the competitors. If your team is more than 5 people or you have multiple teams, you're absolute going to need all that sophistication from JIRA. If you ask me what's the worst piece of software I use every day today, it's Asana.
In the US there are plenty of poorly maintained vehicles on the road emitting a lot of other nosies - squeaky belts, damaged or missing mufflers, rattling panels, worn brake rotors or pads.

Most states have very lax inspection requirements.

Even in my state, which supposedly is one of the strictest on inspections, it's surprisingly easy to have a dangerous failing car pass.

Living near a busy intersection you hear all sorts of weird mechanical failures as cars brake and accelerate from the stoplight.
It's not better than Windows 8.1 in any dramatic way, but it's chokeful of junk than no user wants - ads, telemetry, forced updates, the whole OS-as-a-service angle, etc. You don't feel like you own the machine anymore. It's like you bought it just to let Microsoft to do as they please with it.

Then, there's also the UI that is just... awful. Touch-oriented white-on-white macro bullshit for people with poor vision. It's a smaller gripe and easier to fix, but still.

Windows 10 really feels like something that Microsoft decided to stuff down everyone's throat just because they were in position to do so. It clearly shows that MS treats users as a cattle, basically. You can moo all you want, but that won't change a thing. If you don't think it's true, look at LTSB (or what it's called now) - that Windows 10 edition for people who are really paying. Can't piss them off, so - no ads, no Windows Store, no Cortana or any other crap just gushing out mainstream Windows releases. So it is perfectly possible for MS to release reasonable OS editions _and_ they readily recognize their bundled junk for what it is, it just they don't give a fuck of what unwashed grey masses want.

So, yeah, Windows 10 is the worst piece of software. Not because it's lacking in the tech department, but because of a fundamentally rotten and disrespectful attitude towards their users on Microsoft's part.
Slack. Hands down.

No issues with the actual product per se, which is quite nice. But the experience while using Slack goes bad exponentially as the team scales if certain usage guidelines are not put in place.
Do you know ConEmu? It has pretty extensive configuration and is under active development. Though I am not that much of a console user so I wouldn't know the pitfalls, if any, I just love it because it's so configurable, and it's been very good to me.

documentation has to be actively maintained, but even old and innacurate documentation can serve as a starting point (and be update to be accurate) when something needs to be investigated/refactored etc

without any documentation, all you have is word of mouth, and when people quit, the organizations knowledge DECREASES over time

> people waste time on writing documents that just sit there unread. No one wants to RTFM

documentation is hard... most documents that i have seen are mostly brain dumps, very badly formatted, just very hard to follow...

one thing i think severely missing in school and otj training is how to write documents people WANT to read
I was born in the country (UK) we could hear individual cars coming from a mile away. We live about a mile from a 2-lane motorway: it's been bliss for me in the depth of lockdown that at times it's been silent, and again I've been able to hear (quietly) individual vehicles at night, or none at all.

My kids, brought up with it, were surprised to even be told there is motorway noise, they simply don't notice it.
Slack needs a tweak to the message editing. Inline editing would be nice, instead of having it the new message area.

Surely you would admit that this breaks down in many cases. Suppose you are teaching someone to drive. They might have some funny ideas about what they can do safely. But there isn't any room for debate. Same if we are building a bridge. I can't come in with some creative new idea and implement it with out first learning the right way to build a bridge. Nature doesn't have some mental model that I can choose to disagree with. It is what it is and I have to adapt my model or suffer.
* Jira - over-engineered, unnecessarily complex and utterly slow.

* Zoom - worst video conference product __EVER__. Can't say a single good word about it.

* AWS admin console - same as jira, at least it's not slow.

* VPNs in general annoy me beyond reason too. At this point I use a raspberry pi to connect to the vpn and I use it as an SSH access server (and tunnel respectively).

Killer info, thanks!
How would you create a training program to teach all of lessons?

I thought of creating a workshop at my uni, titled "how to ask stupid questions?" Essentially, do group activities where someone presents on some topic, and the goal of the audience is to ask genuine "stupid questions" - questions about the fundamentals, which most people are embarrassed to ask, but which play a big part in understanding.
Yeah, you need to master JQL to be able to find anything. Once you do that however (and once it's configured properly) Jira is actually quite enjoyable to use. I had a couple of episodes with other issue trackers and I always missed Jira.

And since we are complaining about search feature I must mention Confluence. Like I've said you can query Jira with JQL but in Confluence you're out of luck.
