Keep in mind that at this point, the solar panels may be the cheapest and longest lasting component of your build. My 5Kw system has about $3k in inverter+charger controller+battery, $600 in solar panels (producing 2.6Kw peak), and I spent about $250 on angle iron and fasteners. Batteries will need replaced more often. Though in the article's case, if your pump can run across a wide range of voltage, you could skip quite a bit and just run your pump directly from solar during the day.

General life expectancy of a solar panel is 25-30 years. If they get damaged though (cracked glass), that will let water get into the cells and that will drastically reduce life expectancy. But otherwise, a nice long life. They'll also keep operating beyond that lifespan, however the cells do degrade and produce less power.

Where it gets interesting though is that the cost of solar keeps decreasing and the cells themselves become more efficient. I have some used solar panels that are 78" x 39" and produce 265W. I got 10 of them for $600 shipped (technically $400 for the panels and $200 for the shipping). So used, I'm about 23 cents/watt shipped; 15cents/watt basic. But obviously no warranty and these are less efficient. You can get a used 380W panel that fits in the same space, but around 59cents/watt. In a few years, those 380W panels will be even cheaper, and I could theoretically add an additional KW of power on the same footprint on my roof.

New panels will run about $2-$4/watt. Each generation of solar tends to be more efficient, packing more wattage into less space, and each generation often leads to some place deciding to replace or upgrade their 10-20yr old panels, which then end up on the used market benefitting people like me.
This unnecessary condescension is made all the funnier by the fact that the quote the expression alludes to wasn't actually written by Mark Twain, but in all likelihood by a French writer named Nicolas Chamfort.

I agree with the sentiment that google search results are not what they used to be. And its google's fault. Not as much because of their search algorithms as it is their ad business. Talking pure about tech articles on the internet, Google's ads have corrupted the previously benign and even helpful blogs and other sites and turned them into ad peddlers. I mean who wouldn't want a recurring revenue stream?

That kind of reached its zenith (or nadir) when companies started sucking in articles and employing people to write tutorials just to get ad dollars. Every one of the tech articles. I am sure the other fields are the same way. So unless you know a site you want to search in, the results are all ads not real content.
You're talking about regular running, not trying to literally be the best runner in the world. Completely different.
I've come to the conclusion that tech is one of the least meritocratic industries in our economy. As a result of this, many older workers who "didn't make it" are deeply frustrated by the increasing gap between their ever improving skills and their ever decreasing remuneration. This frustration with the system is also what makes them undesirable to hire. They don't believe in the meritocratic fiction so if you hire them, they may cause cultural problems and dissonance inside the company (and they may come across as apathetic).

To make matters worse, those who succeeded have an incentive to strongly believe that the tech industry is a perfect meritocracy, so they feel like something must be wrong with these older people and this is why they still have to work as developers and didn't progress in their careers.

The affront which reality may pose to their egos, causes employers to hire inexperienced, starry-eyed developers on huge salaries who create chaos and busy-work for themselves whilst yielding diminishing returns and barely getting things done. But the monopolistic, winner-takes-it-all, easy money situation of this industry allows employers in many sub-sectors to make these terrible decisions whilst continuing to thrive and this allows them to maintain and even reinforce their false ideologies about youth and productivity in a vicious cycle of increasing mediocrity.

> ... net present value of the future payments required and attributable to the service of Postal Service employees during the most recently ended fiscal year

This means you calculate the total amount of added expected additional pension payments earned over the last year of work.

So, if last year you could have retired with a pension estimated to pay out $100k, and this year your pension would be estimated to pay out $120k due to the additional year of service, then that number would be $20k.

Since that $20k is not paid out all at once, but over a period of time in the future, you calculate the net present value which reduces the amount based on a “discount” rate which is the expected rate of return on your cash. So, $20k paid out over 10 years starting 10 years from now is discounted to, e.g. $14k, which is how much money you need invested today to fully fund that liability in the future.

To sum it up, in that hypothetical example, the USPS is supposed to be banking that additional $14k to find the future liability.

It’s actually exactly what anyone running a pension program absolutely should be doing.
> Here is the project get it done and its done.

Haha, ohhh boy do I wish that were true.

Thanks for your help with this this quarter. You’re meeting expectations.
Technology moves on. The same shift also happened with cars. I remember when there was pushback (ok at least hearing about the pushback) when cars started to use computers. Why does it have to so complicated? Why does everything need a computer?

You know to a certain extent those folks were right. But you look at cars today and I couldn't imagine my car not having a computer. Adaptive cruise control, lane keep assist, apple carplay, I could go on.

The problem I see now is that privacy is still a pretty novel concept among the regular user so companies in the mean time can get away with overbearing data collection. My prediction is in the next 3-5 years, users will start to get savvier, and overbearing data collection will become a taboo and no company will do it because users will revolt.
A retailer takes on responsibility to back the product they sell. Usually there are channels (i.e. RMAs & loss allowances) that are provided by the distributor or OEM to help retailers take care of this function. In short, if you want to distribute your product through retail, you have to support that model. Consumers do have rights and one of them is to be able to get a refund for unsatisfactory/defective product, even if it is digital.
American police forces have training exchange programmes with multiple national police forces. Yet you'd never hear that say Mexico police is responsible for Georgia police brutality. Not germain enough I guess.
> Python 3 attempted too much change at once.

Python 3 got this so, so wrong. It changed enough to break everyone's code, but not enough to make upgrading worthwhile.

It could have changed more, or changed less - done right, either would have been better than what actually happened.

> How does this lead to making "so much money"? Purely from hardware sales?

Yeah, hardware margins for gaming systems are often not great. The point is that you also have to buy games for it. Similar to how printers are priced (it's the ink that makes the money).
Have you manually reviewed some of these clusters? Automatic clustering for subjective topics tend get gamed by users (if they can be influenced by users) or labeled incorrectly.
I disagree. The last couple places I've worked at have all had their mail hosted internally, meaning on a dedicated IP from one of the big ISP's on a business plan.

No real issues. Sure, you make it on a spam blacklist once in a while, but at least you know when it's going to be fixed, instead of dealing with zero response (or denial) from a big hosted mail provider.

Besides, not all of "our email" comes out of our office, our CRM and ERP products send mail on our behalf, and they have problems delivering mail more than we do.
Assets experienced a 1,000% inflation. People can still scrape by being consumers and renters (cost-of-living), but owning assets moves farther and farther out of reach.

Since our economic system is built on assets (they appreciate, you can borrow against them, etc.), the inequality gap keeps growing.

That first link is just a Q/A. There is no study or report linked.

Almost all studies use untrained vs trained athletes. They rarely qualified what "trained" means and could be anything from a lifetime athlete to someone who self-reported following a 6 week plan prior to the study and now we consider this person "trained". Most athletic studies are used to compare a sedentary person to someone who workouts casually (less than about 10 hours per week). Once you pass this point, you're in diminishing returns territory and you've got to actively sacrifice some parts of your overall health to make gains in a single activity (sprinting, jumping, etc.).

So will running a few times a week help fight mild arthritis? Probably. Will training like an Olympic athlete? No. Same thing applies to the OP article. Will sledding down a hill give you brain damage? No. Will constantly sledding at Olympic athlete speeds and g-forces? Seems like it.
I hope so, but I think it'd be only some of the people. On the one hand there's the reality of what they're doing, and on the other that's a recipe for circular reasoning and making the person more extreme: basically, now that they've murdered a bunch of babies they REALLY have a reason to think even the babies are VC (or Antifa, or what have you)

China has done this too and will continue to do so. They've also recently perpetrated genocide, ethnic cleansing and massive oppression of their population.

It's very hard to compare countries, and there are certainly major problems with civil rights in the US, but I'd rather live in the US than in China right now.
Ask HN: Responsibly report possible fraud vector to Big Bank?
I've recently seen a potential opportunity for fraud at a large US bank that would be easily and relatively inexpensively exploitable. After expending all of my Google-fu trying to find an email address or a phone number to try and report it to, I eventually just called the support number for the bank and reported it to a kind customer support rep who took the details and let me know it had been reported to corporate. However, after a few weeks the vector is still open.

Obviously my only intent is to get the hole patched so that everyone is safer in the future, but I can't find the avenue for doing so.

Anyone have any advice on finding the right people or contact info for doing responsible reporting to Big Bank Cos?

without even mentioning that it creates exactly the opposite incentive.

> Secondly, it's important to note that in Germany, Deutsche Post DHL delivers 95% of all packages within Germany on the next day.

Maybe DHL claims to have attempted a delivery for 95% of packages within a day (even that does not match my experience, average is more like 2+ business days) but that doesn't mean that the package was delivered or that a delivery was attempted.

I have had DHL claim to attempt delivery while I was home waiting for the package. No one rang the doorbell that day. No, this hasn't been a single occurence. Yes I have complained. No, this hasn't stopped happening.

I have had DHL send back international packages because they supposedly had made one delivery attempt (with no notification left behind) and then given up.

I have had DHL lose packages for months, only delivering after complaints and with no explanation of what had gone wrong.

Every international package I received had detailed online tracking until the moment it reached Germany where all updates stop until the package is delivered (if it is delivered).

DHL stopped making multiple delivery attempts for most packages and instead of stashing the packages at the Postfiliale around the corner they send all undelivered pacakges for the city to one or two places, causing literally hour long queues of people trying to get their stuff (not to mention the wasted time getting there in the first place).

I have had DHL claim a package was dropped of at a Postfiliale only to have the people there not find any records of the package even days later. And worse, they didn't launch an internal investigation but just directed me to the public DHL service hotline which is good for only one thing and that is wasting your time.

DHL / Deutsche Post is complete garbage and badly needs oversight that actually holds them accountable.
a) is a good point. I often rename parameters after a while to have more precise meaning. But I guess the advantages of named parameters outweigh the potential drawbacks.
Show HN: Evryca–platform for collecting questions and ideas, e.g. for streamers
Question - why is it that experience / age / wisdom is an asset in other professional trades [1], but it is seen s as a liability in tech?

I have a couple of theoretical answers.

One, perception of tech workers being semi-skilled labor (like low level clerical work) lending it to being managed with "cost center" economics. Middle managers from baby boomer and gen x grew up with idea that tech can easily be "off-shored." The perception is that tech work is a necessary cost, not a strategic element of pretty much all businesses. However, the next generation of middle managers that grew up not knowing what life was like with out the internet will recognize how important tech is to the business and will shift the corporate attitude towards tech work.[2]

Two (this one will be a lot more upsetting), tech workers were introverted and passive, which makes them easier to take advantage of by middle managers who are not afraid to bully them around.[3] So when tech workers get laid off after age 40, rather than fight and adapt, they blame ageism and go quietly into the night. However, the next generation of tech workers seems to be a lot more assertive in their comp and career expectations. I know I am.

Three, a combination of the above.

Fourth, none of the above and I am full of $hit. In which case, I am interested in others' thoughts.

[1] Law, medicine, finance, accounting, etc

[2] A quick story on how corporate culture can change between generations. When IBM was first trying to sell their PCs to businesses, none of them were buying. So they hired a consulting company to figure out why. The consultants came back and said to IBM that the problem with their PCs not selling was an actuarial problem, not with their strategy - the younger people at those companies were excited about new tech, but the decision makers (many of whom were much older) did not see the value of new tech. Consultants told IBM to wait until the decision makers retired. The rest is history.

[3] I have seen this play out, where tech workers are too intimidated to push back against poor business decisions, like over-optimistic delivery deadlines.
Lately we all have seen a lot of streams.

I've noticed how desperately every streamer tries to find questions in a long chat history.

This definitely lacked of some convenient tool:

— I’ll make it!, — dawned on me.

But it was not that straight — I already had an idea of a platform with working title “Add, Fix, Remove”. Place, where, say visitor of B&B, can leave not usual feedback for future visitors, but some advices for a host: “Add hook on the bathroom door”, “Fix stinky sink in the kitchen”, “Remove that round table”, etc.

I agreed with myself that it should be one thing. So here it comes — https://www.evryca.com

For the sake of progress through exchange of ideas.

Will be glad to get some advice on what pitfalls I should expect, while building discussion platform.
Also an older dev (56) and I agree with other's comments that learning the myriad FE frameworks feels like chasing my tail.

I've carved out a role where I work primarily on the back-end of my company's platform, about 50% coding, about 25% mentoring/coaching, and the rest is working with our product managers and business users to develop new functionality.

I feel valued and feel like I'm making an important contribution to the company.

But I am concerned that one of these days I'll no longer have the cognitive muscle to do all of this.
I assume the suggestion isn't that Nintendo should give the games away. Just that if you buy a game on the Switch you shouldn't have to buy it again when you upgrade to their next console.
Think this is a smart move - a LOT of other companies spending energy trying to figure out when and how to phase people coming back to the office, this approach shifts it down the road and says lets just focus on executing here and now.

Reality is if people did start coming back to office that could easily get reversed in a few months.

So again I like the idea of kicking the problem down the road given what we know today.
Finally, after years and years and years of being told over and over and the bottom line never improving.
