Here a few things to note:

BTRFS has had Copy on Write disabled, while ZFS (not possible, cause the whole idea of the FS is intended to be copy on write), which actually makes BTRFS look even worse compared to ZFS, cause BTRFS writes once instead of twice and has most of its features not work, while still performance pretty bad. But then it's also younger.

Both ZFS and BTRFS (only know specifics of ZFS) can be configured to be better for DB workloads. On ZFS, I know a couple of people using it cause it has nice properties.

Anyway. You might not want to use ZFS or BTRFS for a (pure) database system when performance is the important thing (compared to data security).

What I find kind of missing is UFS because of the BSD world (it's kind of what Ext4 is in the sense of "your general purpose FS with good performance for DBs"), but okay.

And yeah, that all may sound a bit biased towards ZFS, but so far my experience with ZFS has been rather pleasent compared to BTRFS, but again. You might wanna use UFS or Ext4.

It's also kind of "wrong" to compare those file systems. It's like while you could use Redis and PostgreSQL for the same things it's probably not what you want to for one reason or the other.

But then of course it's good, cause you might really have a thing where you want to have a comparison of those two things to take the right decision for your specific application. Like those cases where you say "It's slow, but it makes a lot of thing easier" or "It doesn't guarantee that, but when I take care of it in the design I will only need only a fraction of the resources. And the other downsides don' t annoy me thaaat much".

Because the question came up. COW means Copy on Write and it really means what it says. You copy the data (so have find and to write blocks, duplicating your data on write) which in case of a full blown database which does that again (WAL, Autovacuum, keeping lots of metadata, etc.) you really shouldn't be surprised that it's a lot slower on write heavy sytems. It is more than expected.

On the other hand because the FS does a lot of things in a similar way to a database, other than snapshots and replication and all that cool stuff ZFS does things related to metadata extremely quickly and that's why some CDNs that have many small files use it. Besides just being an amazing thing for managing your data in general.

Also if you wanna learn more a about ZFS and have a good understanding of how you can run databases and other things on ZFS and really utilize it (not just gaining more performance) then I highly recommend the book FreeBSD Mastery: Advanced ZFS.
Your complaint is more about implicit vs. explicit. Implicit behavior is bad when it's surprising. When it's what you would have done anyway, then making it explicit creates an unthinking, tedious ceremony that you repeat daily.

Some of my favorite Rails devs are former Python devs. They appreciate conventions and the freedom they give you.
A one-state machine that immediately halts, will always halt, regardless of the input.

The halting problem cannot be solved in general, but some programs can be proven to halt (or not halt). That's how the first few Busy Beaver numbers were found.

For something more substantial: a correct program that implements a regular language recognizer will always halt eventually on any input, because it always makes progress and doesn't have any nonterminating loops. It consumes the whole input and stops.

The hard part is proving you wrote it correctly, but that's what coq et al are for.

Which is not what I said, so I have no idea what exactly you "very strongly" disagree with - it's all in your head. You disagree with your own vivid imagination.

I'm not a rails dev, but I believe that you are misconstruing his argument. It is not about inevitable complexity, but about the ownership of that complexity. If you are able to control the side effects part of development, you can control how it scales and debug it much more easily.

ClusterHQ's tests were unable to detect a difference between the platforms, with the exception of SELinux where performance was degraded unless xattr=sa was set. The code bases are almost identical, so performance differences tend to be caused by external factors and/or compatibility shims. There are also cases where one platform has a performance improvement before the others because the releases and porting are not done in lock step.
Why not? You use the word "should" without a good counterargument to the parent's point, that there was no other way to blow the whistle.

My dad required his kids to change a flat AND read a map before we got the car keys. AAA membership was for maps only. There was great pride in planning our own trips on our own and TripTiks were not for our family because we could do it ourselves.

Map reading skills was the beginning of a love of super-geography (as my professor called it, "the whyfore of where.")

Plus, a map was the first use of different letter sizes, colors, etc.. that I can remember.

> compile times for Java are effectively zero

Compile of a single class yes, but most J2EE projects I worked on compile between 10-20minutes including tests. Sometimes longer, a lot longer...

While writing code in some languages is slightly faster than in others but most probably by less than a factor of 2 (provided you're using the right IDE and know what you're doing).

The increase in productivity we can achieve is "standing on the shoulders of giants": ie. assembling / wiring together pre-existing bigger and bigger pieces of code we can trust and know how to use. Also more and more problems are solved and in public domain.

But if the entities you're disobeying regularly take extra-legal actions themselves, and the consequences of your actions are almost certain to result in extra-legal punishments (rendition, torture), what are you to do? He has to expand his "concept of the rule of law" to account for the ways the American security apparatus have expanded theirs. Perhaps the NSA bigwigs view their secret, self-authorized expansions of power as being aligned the "spirit of the law"; I'm sure Snowden felt the same about his actions.

Also, he didn't plan to end up in Russia.
> First of all, it worries me that many people react like that. We’re discussing a tool, not a person, no need to get emotional.

Laughably, no.

Code is written by people; it's essentially a set of ideas that execute and do things in accordance with the vision of the creators. The creators poured themselves into the tool. Code is an extension of the self.

(If it isn't, it should be; people take the best responsibility for code when it's like that, and it's probably the main essence that separates OSS from most proprietary work. People don't fully invest themselves into creations that can completely disappear out of their lives forever upon the next organization restructuring.)
As an American myself, I would consider it fair to say that Americans are relatively uneducated on global affairs. Do you have some data suggesting otherwise?

Also, I think you've confused a general with a universal. I don't think he was saying that "all Americans" don't know better, just that when confronted with dumb statements it's better to presume ignorance than malice.

As an example, National Geographic did a survey in 2002, and young Americans came in second to last:

http://news.nationalgeographic.com/news/2002/11/1120_021120_...

"About 11 percent of young citizens of the U.S. couldn't even locate the U.S. on a map. The Pacific Ocean's location was a mystery to 29 percent; Japan, to 58 percent; France, to 65 percent; and the United Kingdom, to 69 percent."

On the one hand, I find this a bit appalling. On the other, I can't totally blame people; America is big enough and far enough from everything else that relatively few Americans ever leave the country, and those who do mostly stay on the continent. So I don't see a "assume ignorance, not malice" posture as an insult; it's mostly what I do myself.
Phoenix v1.3 is adding an `--umbrella` flag to the `phoenix.new` generator for first-class umbrella support out of the box. In the Phoenix book we also have the reader breakout their application in an umbrella for the domain bits and a web app for the phoenix bits. Umbrellas have been a little underserved in the community so far, but stay tuned for future improvements around this.

I've also seen the writing on the wall for leaving Rails/Ruby. I think a lot is down to Ruby the language simply not being well-suited for an increasingly multi-core/concurrent future. That said, a more reasonable approach is to begin transitioning a few projects at a time, and make sure you've solidified on your new tools of choice before chucking the old ones.

I remember a few years ago I teased with ditching ruby for node.js. I'm glad I dipped my toes in the water and waited for Elixir.
One bug does not mean disaster there is a function to update to a new contract. Also its unlikely that a major bug remains. Due to testing and review. I cant see how a serious bug can get past so many people and hide in less than 2000 Lines of code.

> about how complex web dev is

Isn't that part of the problem? Webdev is complex. But it feels to me like it's been overcomplicated by a factor of 100. It doesn't have to be.
Another Bernie supporter here, but I think you're overestimating Trump's chances against Hillary. They're good enough to be frightening, but I'm not sure he's the favorite, much less the "heavy" favorite. As bad as her negatives are, his are much worse -- he's already alienated almost everyone except his committed supporters.

We live in interesting times, and it's going to be a very interesting election year.
