I have switched to using NiMH rechargeables almost exclusively now, even for low power devices (e.g. remote controls, clocks). The problem I have encountered with alkaline batteries is that they leak chemicals which can destroy the electrical contacts and sometimes the entire device. I've never had a NiMH rechargeable battery leak in the roughly 15-20 years that I've used them. But I have seen so many alkaline batteries leak that I don't trust them anymore. Maybe it's my imagination but alkaline batteries seem to leak far more often today than 10-20 years ago. Is it just me, or are Duracell brand batteries worse than others in terms of leaking?

The traditional argument for not using rechargeables on low-power devices is that the self-discharge rate for the rechargeable battery is higher than the power consumption of the device itself. However, some NiMH batteries (e.g Eneloop, https://eneloop101.com/) seem to use a special chemistry that results in only a 30% discharge after 10 years. I use the Eneloop brand pretty much exclusively. I think the extra cost of the rechargeable batteries have more than paid for themselves by avoid the damage caused by leaking alkaline batteries. The cost of NiMH batteries are now low enough that they may be far cheaper than alkaline batteries for almost all applications.
Yea, there are a few hidden test cases so people don't hardcode in the answers. A quick hint for the first one is to use a stack, it makes the question much easier.
I get the feeling OP is saying this sarcastically, as a way to criticize China.
It never ceases to amaze me how transparently people project their insecurities. I read your post. It was far too long, and all over the place. My response was focused only on the aspects I find relevant to the discussion at hand. I do not need (nor have any desire) to pick apart every point you attempt to make, however inaccurate or imprecise I find them to be, in order to compose my argument.

>For your Program to be OOP there must exist methods that mutate state

Provide me with a single resource that supports this claim (emphasis on "must"). I have found exactly zero corroborating sources that affirm the above, but many that (coincidentally enough all agree) mutability is an implementation detail in OOP. As far I have seen your logic is:

1. Objects _can_ mutate state

2. OOP uses objects

3. OOP _must_ mutate state

Something is amiss... But digress.

I have quoted, a number of times now, the single excerpt from your OP to which I sought to add some clarity. I suppose I can do it again:

>If that method was never unionized with state, if we used smaller subdivisions in our code where state and functions are separate entities then this would be much less of a problem. The function would not be tied to state and that function can be executed in the context of anything.

It's rather narrow in focus, and suggests that separating functions and state leads to more modularized/portable behavior. My response is rather simple in substance: Simply reorganizing `noun.verb` to `verb(noun)` doesn't make any difference in terms of modularization. In other words, the `verb` is tied to `noun` in either case.

That is _not_ to say there is no difference at all. In terms of extension (the expression problem) it is well-known that basic OOP and basic FP are complimentary in this regard. Where OOP allows for open extension of data, FP allows for open extension of operation.

TBH FreeNAS is a great NAS/SAN solution. I'm running a 4x4 RAIDZ2 (8TB effective) with a 10 year old quad core AMD and 16GB DDR2 RAM.

If you are okay with the limited VM hosting capabilities of Freenas (headless VMs and containers on the same network as the file server) then you can use it for that as well.
What stops the cars being charged at the parking lot at work or shopping/errand locations?

"Before having her own kids, Whitney Phinney acknowledges she thought of paid leave and subsidized child care as "handouts.""

This right here. The American myth that anyone can make it if they just work hard enough goes hand-in-hand with the "pull yourself up your own bootstraps" mentality. And poor people don't deserve welfare because they are "lazy". And other tropes pushed out by conservative think tanks since the 1970s that have Americans acting, and more importantly voting, against their own economic self-interest.
The restaurants are almost entirely owned by franchisees and run on fairly tight margins. You can argue that the corporation makes too much money or whatever, but they’re not the ones who will be screwed if I’m right.
It looks like a 50% reduction of the data exchange rate, but I think it's relevant only for the full nodes, that are currently only 10000 https://bitnodes.earn.com/ (I guess the pools servers, some big exchanges, and a few enthusiastic.)

It adds more complexity to the software and network, and the reduction is not huge, so I guess it will not be used.

The point is - it is truly 100% free at the level that actually matters: the user controlled operating system. This is the point where I feel completely comfortable with calling it "100% free" without further explanation (especially when the last, and I think the only, smartphone to ever reach that level was GTA02 from 2008), just as I am completely comfortable with saying "I made this cake from scratch" without having invented a universe.
That’s pricey per kWh - lithium tech generally is. I’ve just installed an off-grid solar system, and ended up putting together a spreadsheet of a whole bunch of battery options, got prices per kWh, and then built in a factor for lifetime/max cycles.

Ignoring max cycles, the cheapest lead acid I found was £87/kWh. Lifetime was poor, however.

The best bang for buck was OPzS lead acid cells - £115 per kWh, and a long, long lifetime and high cycle count. They’re the most commonly used cell in new grid-scale solar installs, and it turns out there’s a reason for that - over 15 years, they cost less than 20% of lithium over the same period.
You're correct in describing this attack, which is on the TCP/IP stack in various Unix-like operating systems.

I was describing the behaviour of rather newer systems like QUIC, TLS 1.3 and WireGuard which have decided that maybe discretion is the best option.

It seems so far I confused everybody who read what I wrote, (at least everybody who replied) so I apologise for that.
This is a project I've been working on for the past several months and it has blown me away with what it can do. Definitely recommend trying it out.

I think the coolest thing about it is in any other game you are constrained in what you can do by what the developers programmed in, but here you can literally do anything you can imagine and the game will play off of it.
Your phone can do all the same things as those devices, and it's a better target for attackers because it's always on you.

I just bought into the Nest system (which also had great deals on black friday), and I'm just not worried about it.

In reality, bugging my residence isn't going to result in very interesting data. What exactly do you think is going to happen?

I just assume all of my data is already compromised, and so is yours, and neither of us can do anything about it. I think it's only useful to mitigate real world risks that materialize from compromised data. So PIN-lock your credit to avoid identity theft, physically secure your home to avoid break-ins, block ads to avoid influence campaigns, segment and restrict your IoT devices to avoid jumpboxes inside your network, etc.

If I'm doing something that I do not want recorded, I'd be using linux with a tor connection and strong opsec. The house can still be bugged as long as I don't have a camera pointed at my monitor.

If you're trying to host secret meetings in your house, maybe you should consider building a secure room to facilitate that. There's a reason the feds take this approach with SCIFs, because there's really no other way to do it.
It's a dollar for dollar match on up to 7% of pay. Let's say she makes $100. She puts in $7 and her employer also puts in $7. That's $14, and upon early withdraw she would pay $1.40 (penalty) + income tax (likely $0). She would come out with an additional $5.60.

I would argue it's substantially easier to produce a fully-automatic McDonalds than it is to produce an autonomous car that can actually deal with any reasonable situation in the real world.

With a McDonalds restaurant, you can control your environment almost perfectly. If you throw away the kitchen that was designed to be used by humans, and then develop a kitchen never intended to be used by humans, you can drop a lot of environmental constraints in terms of the automation concerns. Trying to fully-automate the existing kitchen layout will certainly end in disaster.

As you reach 100% automation, it actually starts to get easier because the system is now all oriented in this direction, and you have standardized specifications/interfaces across the board. Also, once you fully-automate a single McD restaurant, the next one becomes trivial because it's simply another copy of the exact same thing.
Awesome list - thanks for preparing this.

> but weirdly it doesn't seem the US healthcare system is designed for that

That's true. Your average interaction with a physician in the US to a 20 minute conversation while they fill out some forms in Epic, barely paying attention, then kick you out of their office as quickly as possible. A month or more later the bureaucratic machines of both hospital and insurance finally get around to sending you a bill for $250+.
I generally agree with the commenter here, its really rare to see a tutorial article on the front page of HN (I work in NodeJS fullstack web development)
Definitely get one. You can get one for under $100 these days, some even under $50. The quality starts to drop at that price point, but they'll be good enough to establish fault in a crash.

They're super easy to use. They constantly write in a loop, deleting old footage to make room for new footage as the memory card fills up, so you don't have to maintain them. And they'll usually have a button to press that will move the last couple minutes of video to a location where it won't automatically get deleted when full.
+1. Team of Teams is a great intro to leadership for tech. General Chrystal identifies the distinction between complicated and complex areas and shows best practices for dealing with complexity (it's not just a semantic argument but actually something substantial, where tech leaders generally deal with complex problems and not complicated problems).
You sound like the kind of engineer that skips code review and deploys an untested feature straight into Production.
The 8-second delay is there to punish users who block JavaScript that is loaded from Google's servers (with ad-blockers) but still have JavaScript enabled.
You may find community organizing rewarding. Depending on your comfort level, you can try things like:
- Volunteer work
- Participating in city/town board/council meetings
- Direct action (eg the TN chapter of the DSA replaced tail lights for free, since broken tail lights are the most common reason for minorities getting pulled over)
- Canvassing for candidates, referendums, etc.
- Solidarity actions (eg joining strike members on the picket line)

If you're not sure where to start, try researching local candidates that share your views and find out which organizations endorsed them.

Less now, for sure, but you're overlooking a major category.

Many of the really bad mutations are embryonic-lethal, which is why a surprisingly high proportion of pregnancies "don't take" or end in miscarriage.
Yet there were many PSAs showing teens hanging out in a car, having a good time, distracting the driver with peer pressure, and causing a crash. And somehow we seemed to get past that.

But yes, that is why I said "good friends" - if you're talking to someone non-understanding where you're trying to "keep up" and can't just interrupt and ignore them at a moments notice, then the temptation is to modify your driving to suit the conversation.

I reckon there is a similar dynamic around texting (dopamine from the social interaction), where if everyone were capable of holding themselves to say one letter every 30 seconds we wouldn't have this epidemic at all. Although to be clear I'm certainly not condoning any sort of texting or app use, they are too compelling.
Ask HN: Has anybody else been 'blacklisted' from Amazon?
For the past 2 years or so, I've been completely unable to use the Amazon store.

My accounts keep getting 'locked' for 'suspicious activity' after a day or so, despite nothing being awry at all. I have a clean history with Amazon.

I have called them up numerous times, only to unhelpfully (and falsely) be told that I'd receive an email shortly. Sometimes they'd just put the phone down and not hang up.

I feel like Amazon are intentionally blacklisting me. It's like they don't want my money. I'd try and avoid them, but they play such a huge role in online shopping that they're practically unavoidable.

Has anybody else experienced this? If so, how did you manage to get it fixed?

Sorry for cluttering HN, but this is the only community I know that might share some experiences/suggestions.
The situation in Bolivia probably had a significant effect.

There's lots of lithium mines there. The new (read: coup) government knows this I'm sure and is looking to get rich off of it at the expense of the indigenous population.

This brings up an issue I wish iOS and Android would solve. Location data is always very specific, as accurate as GPS or Cellular triangulation can offer (down to the centimeter in some cases). However the vast majority of use-cases don't need this level of precision. Maybe Maps for accurate directions require this, but rarely anything else. In this case the OS simply needs to know what country you are in, not what street corner you are on.

Why can't apps request less precise location data, and maybe let the user choose this? Another common example is Twitter, Facebook, Instagram, and even dating apps, don't need to know your location with precision, they usually just want the city or zip code with relative accuracy. My Weather app doesn't need to know what rock I'm standing next to for accurate forecasting.

It seems that the answer raises even more of an eyebrow than the original question... why is UWB active in devices if no end-user application can yet benefit from it?
Given that I'm targeting the developer community, I understand that paying for stuff like this is a huge turn off (at least that's one of the main reasons I'm building this). In the long term I think I'll try making this more sustainable by selling to businesses (which in my mind and from what I heard makes more sense).

Anyways, thanks!
You're right that YMMV, but it is an option with some providers. Even with the penalty you get more income.
Nah, our displays aren't that old.

Many models now include "smart" features that do things like motion blur, contrast adjustment, etc that probably do make the picture look better (i.e., "more cinematic") when used normally. These features just clash with niche uses, like vision research and competitive gaming, that would prefer pixel-accurate, predictable updates.

It's surprisingly hard to figure which consumer monitors have what features. There are "research" displays that don't have these features, are calibrated, update in a predictable way, etc, but they're eye-wateringly expensive.

In some sense, we were spoiled with CRTs, which were too dumb to do anything but sweep from top to bottom, left to right, over and over. Of course, it was much harder to generate dynamic stimuli back then too, so it's a mixed bag.
Corporations are a part and a result of our society. The government should not be in the business of subsidizing companies who aren't profitable enough to pay a living wage, it should just mandate a living wage and companies who aren't able to meet it go out of business. 'Creative destruction' and all that.
Backstory: I'm a senior engineer at one of the world's top 10 tech companies. I've had ADHD (and some kind of light Asperger's) my entire life, to the point where I couldn't concentrate on anything the first 12 years or so of my academic career _except_ for certain subjects that really interested me, like math.

Some things that works well for _me_:

1) Good noise-cancelling headphones. I'm extremely sensitive to noise in the office.

2) Repetitive, monotone music. My productivity rises by 2-5x if I listen to hours and hours of repetitive techno sets. It's like I'm micro-dosing on LSD or something and the code is just flying out of my fingers.

3) Not getting disturbed when the headphones are on. Communicate with your team that headphones on = use Slack for communication, because you are in The Flow State

4) https://selfcontrolapp.com/ to help prevent procrastination

5) Martial Arts with sparring. Could be anything like MMA, BJJ, Muay Thai, kick boxing, boxing, wrestling, some types of Karate etc. Helped me a lot. Not only the obvious (getting ripped/in shape, confidence boost, positive effects on the brain from exercising) and blowing off some excess ADHD energy, but as an introverted nerd you learn how to keep stable eye contact and you stop being irrationally afraid of conflicts. It has made me much calmer as a person, and I don't have any burst of rage anymore. Cannot stress enough how much this has helped my career and at softening the symptoms of both ADHD and Asperger's.

6) Healthy sleeping patterns & diet. Without this, I can fall asleep in meetings (and have done it numerous times).

7) If you work at a company where you have the ability to skip meetings you deem are unnecessary - use it! The less bored you are, the more likely you are to be able to focus and not procrastinate, I think.

8) I like getting out of the office during lunch, just to get some air/sunlight/short change of environment. Feels like I'm less bored when I get back to my desk.

9) If I'm taking on a bit too big of a task, I try to break it down into subtasks because otherwise I get bored and start to procrastinate. I need very clearly defined units of work to work efficiently.
I've heard this echoed by Matt Farah on his One Take review of the Model 3 Performance. He recommended leasing the car as it doesn't seem like a "collectors" item. Essentially saying it was built to be used for a few years, and then recycled. Much like old iPhones are these days.

I certainly wasn't claiming all Amazon products (or even some of the home security products in isolation) were upper middle class.

However, most at-home services _are_ upper middle class, and owning a reasonable number of security products is upper middle class. Furthermore, we're interested in the intersection of those two things, implying an even more well-off group.
She isn't paying $370 out of pocket though. She could be paying $0 out of pocket using the advanced payments to pay for her premium. And tax credits can make it so you are owed money by the government - it doesn't matter if she pays $370/mo in taxes or not.
