Should it be illegal? License plates are in public view, so it seems they're meant to identify the vehicle for whomever sees them.

If people have the right to record that number when reporting a crime (which they sometimes do) then surely the government has the right to keep track of it as well. That is presumably why they issue the plates and require them to be visible to begin with.

It seems unreasonable to allow the existence of license plates and then complain when they're being used for their intended purpose.
2009 is hardly 'recently'...
Postgres uses a specific brand of MVCC (https://en.wikipedia.org/wiki/Multiversion_concurrency_contr...) where multiple versions of a row are stored in the heap. That's why there's vacuuming to remove those.

To avoid having to vacuum whole relations all the time there's the "visibility map", which keeps track of which blocks have no dirty rows; so they can be skipped during vacuum.

To understand which versions are visible postgres stores transaction-ids in the row headers; these are four byte wide. On systems with significant throughput, those don't last very long. So every now and then there's anti-wraparound vacuums; which replaces xids which are about to become "too old" with a special marker ("frozen").

The problem < 9.6 is that these anti-wraparound vacuums have to scan the whole table, thereby are a lot more expensive. These happen every 200 million xids by default (write transactions and/or savepoints), configurable up to ~2 billion. With the freeze map, that doesn't have to happen, only non-frozen pages have to be re-scanned.

Also, any academic post-graduate role is oversubscribed because too many people go to college, and in college, hear a disproportionate amount from people who did well through the post-graduate route. (Though that's changing as the actual instructors are increasingly made of famished adjuncts and TAs.)
It may also be that firms simply limit production. Since taxation is per firm, there are more firms. IOW, it may act as a brake on consolidation.

Note that streetview cars are not only for maps, they're also wardriving cars. They collect information on Wi-Fi networks, so then you can map a router MAC address to a physical location. They used to sniff wifi traffic too.

There was a tool (http://samy.pl/mapxss/) that allowed you to interface that system. When I moved to a new home, my router appeared on the old location for a few weeks, and then it got updated to the new one. Creepy.

> It's about rewarding good service and having a good incentive structure.

I've thought this before, but my current view is that any theoretical benefits of tipping evaporate in the real world. Worse, tipping creates a huge vector for pay abuse, via all kinds of crazy schemes.

Tipping obfuscates actual pay for workers and actual cost for customers. It's delightful to travel in no-tipping countries, and I've uniformly had excellent service abroad. The lack of this "incentive" doesn't seem to have created any service apocalypse.

This matches my experience. That's not to say that your application doesn't need to do any work on top of the data. Sometimes you need to interpret the data in different ways for different use cases, and often that means applying transformations at the application layer. But if you find yourself fighting against your own data model, it might be time to consider restructuring the data to better support your use cases.

This is interesting, but I admit I am a bit confused.

Having read "An Introduction to Database Systems" by C.J. Date (http://www.amazon.com/Introduction-Database-Systems-8th/dp/0...), I have a tremendous appreciation for Relational Algebra and Theory which allows for the closed functional nature/syntax of SQL which holds true across the various normal forms (1st-5th).

Perhaps due to my own lack of understanding, I always assumed that without an underlaying relational model SQL loses its closure. So for me, I always thought the distinction between SQL and NoSQL was whether or not the underlying database model was relational.

Sure for many of the queries against a non-relational model you could adopt a SQL-like syntax (which many languages seek to do), but it would no longer be operating in the closed Relational Algebra space.

Could you comment on this and help me understand the finer points/where I went wrong?

Isn't that the way it already is, for the most part? Granted there are some things that aren't taxed this way (land & food come to mind), but for the most part, as money flows through the system, it is taxed.

Buy a laptop for $1,000:

* That comes out of money you've been paid, presumably, so in 43 US states, you've paid income tax already on it, and your company has paid payroll taxes.

* 45 US states charge sales tax, so you pay sales tax.

* If you paid with a credit card, a cut of your transaction goes to the credit card company, who pays taxes on their profits from that transaction.

* The money is transferred to a bank account, and that bank is taxed on the profit that they make from that deposit.

* The laptop company pays taxes on the profits that they make from that laptop (depending on where they're located, but if it was sold in the USA, they pay taxes).

* Any shipping company involved moving that merchandise around paid taxes on the profits they made.

* The company that brought the laptop into the USA pays the import taxes/tariffs associated with it.

Just at a glance, every time something changed hands, it is taxed. And this doesn't get into things like excise tax, which are even more fun.

>Yes, there is. Modern philosophy is judged by it's intellectual consistency, the simplicity and intuitiveness of it's underlying principles, and how those underlying principles lead to conclusions that make sense.

It is also judged by outcome matters, which is why the west still teaches Foucault and Dedirra, even though they are by far way less consistent than analytical philosophers (who are also taught)

One of the reasons that happened if that some correctly constructed Analytical Philosophical thought gets very non-intuitive results that seem to create exceptions, such as ethics of genocide, whereas classic continental philosophy, because of its room to breath, doesn't.

Hence why philosophy still has problems to solve to this day

Focus on saving. As a developer, you can save a lot of money by the time you're thirty, likely enough that you won't ever need to work again. I'm not saying you'd have to, but you can give yourself the ability to choose when you work, how often you work, and what you work on.
This presumes that VC money isn't also dumb money - often smart (or rather cunning) only in how deals are arranged to maximize leverage over founders.
I agree that it is a niceness tax, and would go further and say that tipping has come to mean more about the person tipping, and less about the service you receive.

When a waiter (or Lyft driver) gets a poor tip, or no tip do they think, "I really should have provided better service to that customer", or do they think, "that guy is cheap."
Do you mean as a contractor?

If so, how normal is it to go through an interview process for contracting? I got friends who told me they had to interview like for a regular position even though they're contracting, but I should say that those I've heard it from are contracting exclusively full-time for a single company. So how normal is it for 3 or 6 months contracting?

He might be including the employer's share of FICA tax.

If you're single and your AGI is $60,000, your taxable income is $49,700 (or lower, if you itemize deductions). You'll pay $8218.75 in Federal income tax, $3081.40 in social security, and $720.65 in Medicare, for a total of $12020.80 (24.2%). If you include the employer share of social security and Medicare, it comes out to $15,822.85 (31.8%).

He probably should have mentioned it if that's what he really did, but those taxes are real. Ask someone who's self-employed.

>Is this to imply there is a more-correct philosophy? I have no formal training in philosophy but I feel that to claim one philosophy is objectively better than another is a bit much.

Quality of thought as better. Internal consistency is but one measure of quality, given that you also want non-intuitive results (EG: Can't justify genocide accidentally with the way ethics is set up, even if all of the pieces of the argument are internally consistent.)

This topic overall reminds me I should write to an old friend with a phd in Philosophy and the son of a phd in Philosophy, a great mathematician (pity he didn't go for the phd in that) and a really excellent talmudist when he feels like it... he probably has thoughts on what they are saying.

I do a lot of public speaking, presenting and demoing to audiences of various sizes, and am considered (by at least some people) quite good at this stuff.

My advice would be just stop and think when you need to. It's completely fine and you will convey the impression that you are a serious and thoughtful individual, which is good. You can show that you were listening and are about to respond entirely through your body language.

If you feel uncomfortable with that, there are a bunch of simple tricks you can use here and saying "umm..." is not a good one. One easy thing is to always ensure you have a glass/bottle of water. If someone asks a tough question and you need time to think, wait until they have finished their question, then take a drink of water. No-one thinks this is even slightly strange and it gives you time to think and make a considered answer.

Yes, i do get claustrophobic (rarely, but yes). If the effort to go forward is hard, you need to take in account that there won't be space to turn around and swim it head first back. So you need to keep in mind that you might need to "finger walk" yourself back - backwards! That is sometimes an adrenaline accelerator and keeps you from doing stupid stuff.

> Any policy that would cause people to be forced from their homes just because should be viewed as a failure.

I have a really really hard time feeling bad for people who bought homes in the bay area in ~1980. They won the lottery. Their home grew 10% y/y for 30 years outpacing inflation by a significant margin. They got a 30 year tax break while their income likely outpaced inflation as well because they live in an extremely good job market. That house they bought for 100k is now worth 1.7 Million. They can sell the home, move basically anywhere else in the country, and retire on the remaining gain. Yeah, I'm having a hard time feeling too bad for them.

On the other hand, the person who moved to SF in 1980 and decided to rent, I feel bad for them. Unless they found a rent controlled apartment, they've seen their rents grow 10% y/y, and if they found a rent controlled apartment they probably got evicted when the owners of the property sold it, and the new owners decided they wanted to redo the property as condos.

Lets just call it what it is, rent control for rich people. Then maybe we'll talk about it sensibly and realize that it's a horribly thought out plan.

What happens when it hits that limit? Crash, or try to GC, or... ?
Yes and no. Take the following with grain of salt as it is just my personal opinion/understanding. Only 1 or 2 points are actually from challenges I have run into.

Restricting every query to a single core places an artificial CPU cap on a system that would otherwise be IO capped.

Disks/storage is also getting faster (http://www.geek.com/chips/new-intel-storage-is-1000-times-fa...).

As analytics keeps gaining popularity, the need/desire to move more and more CPU bound processing to the data storage layer is increasing.

And finally, PostgreSQL's advanced query planning/partitioning support would immensely benefit from being able to split partition queries into multiple process buckets.
This concept already exists, and is called a Flat Tax. The problem is it's regressive, which is the opposite of what the current tax code is attempting to do.
