The easiest way to miss a point (on purpose or not), is to take a metaphor literally.

I see a lot of this here on HN, and I think it is a common vice among people with strong knowledge in the hard sciences but with a rather narrow scope of interests outside of it.

I believe that the point was that sovereignty over how one spends one's time is more important than material possessions, beyond what is strictly necessary. Surgeons can save a lot of money and retire early, probably are less restricted by managers than the typical wage slave, have a very meaningful job (something quite rare these days), etc.

Most people's lives today are not like this. They are stuck in a hamster wheel that they cannot jump out of without becoming homeless.
TV execs need to stop seeing consumers as thieves. This mentality that viewers are the enemy hasn’t historically worked yet they keep repeating it. One exec even accused consumers of being thieves for not watching network ads.

If execs actually listened to consumers then most of these problems would go away. E.g. no DRM in music. But it took Steve Jobs to convince music execs of that.

Execs are only greedily into chasing the money as they are not generally technically savvy. They also don’t understand economics as they always trot out bogus lost revenue numbers where such revenue was never possible as those people wouldn’t watch if they had to pay money.

I'm a single male, 30, who can currently afford to buy a house but isn't sure if I want to.

I understand it's an asset investment, but i fear that it might largely be detrimental to my lifestyle.
I live in a high CoL area (Seattle), when I can only think about buying a house in the suburban area. This will increase my 10 min walk commute to at least 45 min bus/car ride. My social life may suffer due to the distances, but at the same time I want a place to call it my own.

Anyone else going through the motions or have a different perspective on how to figure out my dilemma?!
It's something I have spent a lot of time thinking about, and while I have yet to reach a conclusion, I believe in a function that approaches always enforced rules as penalty for breaking the rules increases. When the penalty is high, the harm the average player feels from someone gaming the rules is preferable to the harm they feel from having the rules selectively applied to them.

I also strongly encourage pointing out the 'real rules' that the written rules are enforced by when they are selectively enforced. Many times they are much harder to tolerate once called out.

I love SQL as well, but SQL is too low level for "data scientists" that are used to copy paste scripts from the internet and working with pre-baked packages.
i've been back and forth on this.

for a while i was very much into ebooks for many of the reasons others on this thread have sited, but eventually started purchasing physical copies again. part of this was uncovering a well-worn copy of Dune in a box. it was printed sometime in the early 1970's and everything from the cracked spine to the yellowed pages to the "sale, 10¢" written in a flowing script the inside cover brings a nostalgic value i couldnt possible replicate with an ebook (for painfully obvious reasons). furthermore, on uncovering this book i found the bookmark to be the receipt from the bookstore that i purchased it from a decade ago. other books on my shelf contain similar personal items such as a postcard welcoming my daughter to kindergarten, a $1 silver certificate i found in my change years ago, a receipt from a store that i used to frequent as a teenager whose proprietor has since passed away...

[edit]: correcting a typo
Some of us who have at least some involvement with security do have to cringe a bit at this. Yeah, I have a unique password for Netflix and there's only so much harm someone with access to the account could do. But don't share passwords even with people you trust is still ingrained enough that it just feels wrong and certainly isn't a good practice in general.

Who knows who a kid, for example, is going to share the password with?

Though, as you say, requiring the password to be shared to share the account probably helps limit how casually people will give others access.

Firstly, who still does this? Nobody I know in the scuba diving community "[studies] old maps and stuff searching for lost treasure". That'd be a good way to not have a dive plan and end up in trouble.

Secondly, no scuba diver is about to dive on the ocean floor. Maybe you're thinking of deep sea divers, who dive in a submarine or other deep sea vessel?
Your post is an anthology of myths and incorrect information.

Some facts:

* Nuclear energy has received less than 50% of the subsidies that renewables have. Renewables only recently ceased to "need" this, and they've been under development for decades. Nuclear power hasn't had investment in significant research since about 1970.

* Nuclear reactors are competitive in many countries, and in fact they are too in the US. Nuclear is the cheapest power per kilowatt-hour except when direct access to nearby fossil fuel sources is available, even using 40-50 year old reactor designs. Newer designs would be even cheaper. In fact this is irrelevant, however, because we're not looking for the cheapest power, we're looking for a way to supplement renewables with always-on electricity that doesn't fuel climate change.

Newer reactor designs will be safer, cheaper, and less expensive to build. They may even use something other than Uranium as a fuel. They will not contribute to nuclear weapons proliferation and they will not produce large amounts of waste. They will release less radiation into the environment than current coal plants do.

If all the people who believe 40 years of propaganda and misinformation spread by self righteous willfully ignorant individuals can do so, we can work toward a clean energy future using renewables and nuclear in time to limit global warming.

If we can't, once we start having wars over water and the world starts boiling in the heat of rising seas, we'll start building nuclear reactors after the fact. Assuming we survive that long.

Not really. Writing a SQL migration takes what, 10 minutes max? Or you add the columns as you go, and it all just merges into the normal dev time of the feature anyway.

You'll easily make up this lost time just in not having to immediately clean up crappy data that you've written to the database while you're developing the feature. That's been my experience anyway.

It is very limited because phone numbers are gatekeeped by massive telcos. VoIP numbers are sold in blocks and are easily detected by phone verification systems.
I am utterly baffled by these old solar and wind advocates who suddenly NOW are becoming big advocates of nuclear power.

I have gone the complete opposite and for GOOD REASON! I was a big advocate for nuclear power some 10-15 years ago, because we were promised that thorium reactors, pebble reactors and a whole host of other innovations were around the corner. Not to mention wind and solar at the time seemed to not have made any dent in electricity production.

But to suddenly abandon renewables now in 2019 when wind and solar is seeing staggering success and really impressive price drops while every nuclear reactor is profoundly delayed and over budget is simply odd.

We have been talking about nuclear power for decades and invested massively in it, yet got little to show for.

Prices are not dropping. When you bring up the safety issue advocates are quick to point out todays reactors are much safer. When you point out today's reactors are extremely expensive and slow to build, they counter with that is just because of safety.... eh well yeah. You cannot have a cake and eat it too.

Nuclear power is NOT CHEAP! No private company is willing to insure them. Hence governments have to give insurance for free. That means the tax payer. Chernobyl cost tax payers 235 billion dollars to clean up. Fukushima cost tax payers 183 billion dollars to clean up. Nuclear power is getting a free ride because they are not pay for this. That is a massive subsidy to nuclear power.

Solar and wind meanwhile is beating coal on price even without subsidies. Yeah sure... it doesn't always shine or blow wind. But we have a multitude of storage solutions: thermal, pumped hydro, flow batteries, gas-to-power and there are many good solutions for adjusting power usage on demand to fit lower production.

It seems like these nuclear advocates have not even investigated all the storage solutions that exist before going crazy about nuclear power. These solutions will only become more viable as we get a bigger renewable mix, because it will cause the spot price of power to drop really low, making it profitable for companies to buy and store power.
I used to lament my ultra-slow reading pace. Probably because it slowed down my ability to complete homework in school.

But I've since learned to appreciate how much my mind will wander inside the world of a fiction novel that I'm reading. I'll constantly stop to imagine how this place might look, how I might react to what just happened, what I might think of this character if I were witnessing this with my own eyes. It's part of the reading process for me.

Someone reading so intermittently as to not be immersed in the book or gain much from the book just sounds like someone who is trying to finish a book they don't like rather than some sort of "bad reader."
Depends on the location, but a crashing house market halving the price (or even more) of properties is not uncommon. It happened in the last one.
No, it's because projects with huge amounts of data were growing beyond the limits of what you can reasonably do on one machine. Machines were less capable then (smaller disks, less memory), and those limits are a lot higher now. If your data is small enough to fit on one (very beefy) machine, then it's probably still cheaper to pay for that high-end machine vs. distributing to a bunch of less capable ones.

There are exceptions - distributing the data can be really helpful if you need to do a lot of bulk I/O (ETL jobs, analytical queries, etc.), but it comes at the cost of making "transaction" use-cases difficult and expensive. Using a scaled-up OLTP[1] database for user interaction and a scaled-out OLAP[2] database for analytics and ETL jobs is a common pattern.

People have nearly died because of exactly this situation. See, for example, Quantas Flight 72 [1], in which a pair of sudden, uncommanded pitch-down manoeuvres that caused severe injuries -- including fractures, lacerations and spinal injuries -- to several of the passengers and crew.

A long and detailed investigation essentially concluded that these events were most likely caused by the CPUs not being sufficiently rad-hardened. The pilot was diagnosed with PTSD, caused in part by being totally out of control, and quit his career [2, 3].

I hear the rate of change argument a lot, but I haven’t been able to comfortably arrive at how the comparison is made. Historic temperatures (pre-nineteenth century) have to be inferred from proxies—ice formations, fossilized tree rings, et cetera. Those, in turn, must be put into a date range based on some form of (I assume) radiometric dating. Carbon dating can get you +- 80 years. The other common techniques have even less precision. Uranium-lead dating can peg down a 2 million year window, for example.

How can researchers say that the rate of change is so much greater now when, not even counting propagation of error, the granularity of measurements pre-nineteenth century is, at best, of the same order-of-magnitude as the WHOLE of the era of modern precision measurements?

EDIT: I realize my question is inconvenient, but downvoting without meaningful response is no way to counter skepticism. This topic gets more religious as time goes on.
>nor to worry about future waste storage sites

Why would we need more than one waste storage site?

All the waste produced by power generating reactors in the US ever would fit on a US football field and be about 30 feet deep. That's less waste than one coal plant produces in a decade.

All that waste we can't figure out what to do with, that no one wants to store or transport? That's from making nuclear weapons. No one sane wants more of those.
I wonder why the chart for CO2 concentration starts at 1960 vs 1850 for the global mean temperature difference
Before I started using migration scripts it was a bit of a pain (and before there was off-the-shelf libraries for this), it was a bit of pain. But these days, nope. MySQL is slightly more annoying than postgres because it doesn't let you wrap DDL queries in transactions so you can get left in an inconsistent state if your migration has a bug. Postgres is seamless.

Here are "high frequency" sonar images of the Japanese WWII aircraft carrier Akagi, sunk in the Battle of Midway. They were supposedly taken by an AUV.

Best guess they used the Remus 6000 to find the ship. It looks like a torpedo.

- 3.8 meters long
- 9 km/h speed
- 22 hour 'charge'
- 6000 meter max. diving depth
- EdgeTech 2205 sidescan array (best guess)

The WWII ship is about 250 meters long, so the broad image captures about ... 1.5-2 km? Anyhow, take all that and apply it to roughly 360 million square kilometers (161 for the Pacific). Ignoring an average current here and marine traffic and conditions, just going by ideal specs, that's an imaging speed of about 13 - 18 square km per hour. It would take something like two - three thousand years to cover the oceans.

Logistical support alone for this AUV is incredible: crew of 20, four two thousand horsepower diesel engines eating 54 gallons of diesel per hour each at low throttle. Like 216 - 283 gallons of diesel per hour on average, and not counting electric generators on that vessel. The engines have to be overhauled every 4,000 hours. In other words, this effort would be a massive undertaking under current conditions, and there's not enough diesel on the planet to make it happen.
Like pretty much everything "free will exists" and "free will doesn't exist" are just two extreme perspectives of the same reality.

Start with Postgres. Don't start with SQLite. SQLite is a file format, not a database; it scales atrociously (I've seen simple queries run for 10s of seconds with 100MB of data), it basically doesn't work in concurrent update scenarios, and the more data you put into it, the more pain you'll have migrating to Postgres.

Use SQLite if you want a file format where you don't want to rewrite the whole file for every update, or if you're in a situation or environment where it's not feasible to have an actual database server.
Interesting graphs, but it's a little confusing that all but one of them use difference of the metric (i.e. relative values) instead of absolute values -- what and when are the differences relative to?

>We're building new natural gas plants to provide peaking power

True, kinda, but that has more to do with there being no good reason to build a natgas plant that can't be throttled in response to demand. You can use anything for base load if you want but economically it makes more sense to use the cheapest stuff possible for base and more expensive stuff for daily fluctuations and peak. But coal is getting more expensive and gas is cheap so we see more and more base load taken up by gas. Instead of idling in off hours more and more gas plants are running at low capacity to provide a little bit of base power.

The whole base load/peak way of discussing things is slowly going out the window as more and more power comes from renewable since even base load is going to fluctuate around the grid based on the availability of sun/wind and something (currently gas, maybe storage in the future) has to absorb that load.

I really should have framed things in terms of stability rather than base load. With wind/solar you can't be sure you'll have wind/sun when everyone wants power some arbitrary date in the future which is where storage/gas come in. You have a base load but solar/wind can't be guaranteed to provide base power so gas/storage spins up. From a gas plant or battery point of view a dip in solar/wind capacity is no different than a demand peak on an otherwise coal grid.

not likely the NG didn't add new systems. not saying other cost-cutting won't be exposed but nothing as egregious as MCAS.

the MAX added new engines, which required forward placement on the wings, which changed COG, which necessitated MCAS.

The counterargument you will hear to your strategy is: you can always refinance at lower interest rates if rates go down at some point, but you can never change the price you paid for the home.

Granted, you should do what works for you, but there is plenty to be said for purchasing a less expensive house when interest rates are higher.

That does not sound right to me. Your interest rate would have to be pretty high. I currently have a loan with a 4% rate I got last year, and my friends are reporting getting around 3% currently. With a 4% rate, you should end up paying a total of about $860,000 - $500,000 in principal payments and $360,000 in interest.
I've worked extensively with SQL and relational data modeling. It's been very useful for accomplishing my work. I haven't come across better tools and so I haven't adopted alternatives. If the time ever comes where there is truly a superior tool set to the one I am currently using, I will gladly stop using antiquated technology. Newness isn't sufficient to sway me. No dogma here. Just pragmatism.
On the other hand these black swan events usually aren't that bad. For instance the Fukushima disaster, without an evacuation, wouldn't have killed any more people than a equivalently sized coal plant operating in the same place for as long as Fukushima had operated. The difference is just that with Fukushima the deaths are relatively concentrated in time.

Now, Chernobyl was a disaster you're not going to see with the normal operation of any class of power plant. But hydroelectric dams also have the potential and sometimes do fail in ways that kill thousands of people but I don't usually hear people oppose those power plants on these grounds.

I think that the real reason people have such a fear of nuclear power plants is that we use the same terms, "radiation" and "fallout," for the dangers from a nuclear reactor failure and a nuclear war when the magnitudes are as different as a pebble and a boulder. I grew up mostly after the Cold War and always associated those terms with nuclear power and never realized that if you're a hundred kilometers downwind of a megaton scale groundburst you can die puking your guts out from fallout a couple of hours later.

SQL is indeed a powerful too. But it's just one of many. Just today I used: SQL to dump data to csv, python to modify it, and gRPCurl to upload it to another service. Different tools, different problems, use the right one.

That being said ... RDBMs still suffer from scale and there are many efforts to fix this with sharding to disaggregating the data layer from the query layer with examples like AWS's Aurora and GCP's BigQuery etc -- in all likelihood data will likely live in many different places and will need to be adapted into things like a datastore or queried from things like Hive and Presto, or even a traditional ETL + EDW setup -- my point being there's no one thing that will solve everything as most single solutions break down when the number of rows is measured in the billions or more.
