I'll add my 2 cents :-)

A lot of it has to do with historical reasons which have reinforced themselves over time.

Here are some of the early differences:

* MySQL had an ungly way to allow users to only see their tables. While it wasn't great it was better than PostgreSQL which didn't really have a way to hide other databases.

* MySQL could create and destroy connections quickly. PostgreSQL made more robust connections but they took longer to setup.

* MySQL ran simple queryies much quicker under a light load.

* PostgreSQL database maintence tasks often required the database to be offline.

While these differences didn't make a big difference in a business environment PostgreSQL would have been a better option because:

* Use connections pools and not care about the connection setup time.

* Have a high load and care more about how the database ran under load.

* Have a trusted users and not care that they could see other databases.

* Have maintence periods.

That being said in the business world users used MS SQL or Oracle. Where MySQL took off was shared hosting which:

* Had light usage.

* Limited resources which meant that they often banned connection pooling.

* Had multiple untrusted users.

* Can handle a slowdown but not downtime.

In this situation MySQL was the better option.

This then caused a network effect where most software was written for MySQL so more companies offered it (remember at this time lots of companies only offer static hosting). Since most companies offered it more people wrote software that supported it.

Programs that support PostgreSQL often support MS SQL, MySQL and a number of databases BUT there are a number programs that only support MySQL. This means that if you want to run a number of programs it is easier to run MySQL rather than PostgreSQL since you'll have to run it anyway.

So while PostgreSQL has largely fixed the problems they had on shared hosting MySQL still has the market share.
As I mentioned above, those package managers (apt-get & yum) have never actually worked in my experience. After a dozen failed attempts to install anything with any of them, I had just assumed that they weren't intended to install anything other than a few well-known packages.

Any idea how to teach yum to actually find anything?
If you find "mainstream" coffee enjoyable, is it really in your best interest to raise your expectations? If you suddenly find normal coffee lacking, have you really improved your life?
Erlang would be 'different' than those. Java would not be too exciting or exotic, but practical for many things. If you're not wild about Java, try coding for J2ME or Android... there's less BS in those environments than the 'enterprisey' stuff.
If your original comment really does imply nothing beyond what it literally said, it is superfluous. All it offers is a correlation - which is insufficient to show whether poverty causes stupidity or the opposite - and a qualitative, unsubstantiated 'explanation' for why stupidity causes poverty and not the other way around.

You can save individual pages from a PDF as an image in Preview (scroll to the page, File -> Save As). This won't work if the PDF is protected but that would likely apply to other applications too.

You can also create PDFs from images with Preview. Open an image and save it as a PDF. You can then drag images or pdfs into the sidebar which adds pages to the PDF.

It's not ideal, but it works.
"Web 2.0 zillionaires"? Lost me right there.
It's quite plausible that if you find mainstream coffee enjoyable, you might find quality coffee even more enjoyable.

If you find cheap wine enjoyable, that doesn't mean you won't find a Grand Cru a hundred times more delectable.

So, you have some problems with your iPhone, and you're hoping that the unreleased Palm Pré will get right everything that the iPhone got right, and also fix the things you think are wrong with the iPhone.

Well, what can I say, good luck! It's good to be hopeful!
Quite the opposite, in my experience. The more really good wine I try, the less I'm able to enjoy cheap wine. These days I prefer water over cheap wine, unless I'm specifically trying to get drunk.

The same with coffee... after discovering freshly ground French press, I'll drink and really enjoy two cups a day, rather than the 6-10 cups of stale filter coffee I'd drink previously.

One of the things that distinguishes a good programmer from your average one is a detailed knowledge of the language's standard libraries, even if they're de facto standard ones. How many times have we seen C that re-implements memrchr(3) or strcspn(3), often with bugs.
I love these journalistic pieces where the tone is "I'm totally destroying their argument" but the actual data is lacking. Sophistry of the lowest kind.

Personal highlight: it's okay to fall behind in a certain test because that's "only" measuring the real-world application of maths skills. We want to be judged only on what they've learned in school, because other countries are cheating by learning not just in school but "at home, or even elsewhere".

I mean even if you accept their premise that's still nonsense.
Matlab is a horrible language, although at least it has lambdas now. Have you looked at SciPy? It can't replace some of the more specialized toolboxes of course.

http://www.scipy.org/
Haskell (e.g. http://learnyouahaskell.com). Learning Haskell is exciting (when the headaches subside ;)) and although becoming more popular Haskell can be considered exotic. The best part imo is that learning Haskell's functional concepts is useful for other languages as well.
Yes. And the reason why you enjoy the quality coffee more than the cheap filter stuff is because it is more pleasurable. That is also the reason why you don't enjoy the cheap stuff anymore - because you know that it's actually pretty bad. You can still drink it anyway, but you know it's not that good.

Suggesting that this is a bad thing is kind of suggesting that you don't think your tastes should evolve for the better throughout your life. Pushing this argument to its natural conclusion, we should all just eat candy, drink fizzy soda, and watch kids' cartoons for the rest of our lives. Do you think that's a better state than knowing that there are such things as fine food, great wine and inspiring movies and books?
What platforms or areas are you interested in?

You know C, have you tried network programming or games programming or C on embedded systems?

You can learn a lot by taking an existing language into a new area, it will sharpen up your skills better than learning a language without having a use for it.

Experience is what makes good programmers not a laundry list of languages that you have never used in anger.

I wouldn't say slony is less proven or battle hardened. Being one of the very few postgres replication solutions that actually work it is currently in use pretty much everywhere where replication is required.

I think slony is less popular than mysql replication because it is a royal pain the ass to setup and maintain. In mysql you flip a switch and have replication. It has a few known issues but is "mostly" reliable and understood.

In postgres/slony you enter the wonderful world of triggers and several layers of magic.

I would say the bulk of it is ease of administration, and, as others have mentioned, the ability to get it up and going and use quickly and simply while having a relatively opaque understanding of how an RDBM works underneath.

The other major difference is that MySQL AB put a lot more effort into having an extremely concise, easily navigable and user-friendly online documentation repository and associated support community. Postgres has since made good strides in this area, but a lot of the documentation still reads like something intended for a fairly specialised audience that more or less knows what it wants; the ignoramus-friendly parts of MySQL's documentation are a lot friendlier.

For this and its administrative simplicity, it just got to be known as the quick and easy database, and Postgres as the rocket science database. (In reality, this is not true; only Oracle is the rocket science database. :-)

Also, MySQL was/is more appealing to corporate adopters since an Actual Company(TM) is Behind(R) the project. Postgres has a commercial footprint in the form of various third-party consultancies like CommandPrompt, but the core of the project is a Debian-like anarchic band of hackers. Nothing turns corporate America off more than a bunch of long-haired GNU hippies when it comes to big-ticket stuff, though they begrudgingly put up with it for Linux by now, Linux having become somewhat "legitimised" by the backing lent to it by IBM, the existence of Redhat, etc.
That definitely is important. MySQL has fairly turn-key and easy to understand replication and has had it for a while.

The Postgres crew hides behind the "replication means different things to different people, so it would be quite presumptuous of us to build it!" mantra. It's quite annoying.

You can hack together crude replication in Postgres with Write-Ahead Log (WAL) shipping. The config has some hooks in it to automate this process and bind to it. But that doesn't allow you to do circular and/or master-master replication; the receiving node has to continuously be in recovery mode.

I agree - C or an assembler - anything close to the metal.

Artfy farty stuff might teach you new ways of thinking about problems but not a lot about programming per se.

Alternately - creating a (small) language of ones own and writing a compiler for it would be immensely beneficial.

How do they do virus and security checking? I don't know how they import the data, but it could be that they use a system that can be exploited using a security vulnerability?

It's a (very) long shot for this kind of thing to work, but still it's a risk worth asking about. They are at the end of they day hooking up hardware to their computer - i.e. physical access to the machine.
interestingly enough cleartrip is written in Common Lisp.

It is just as easy to extend any of the scripting languages with C++ as it is with C. SWIG and other systems like XS have built-in support for C++. Even if that weren't true, you can just make your interface header files 'extern "C"' yet enjoy the superior power of C++ in your implementation files.

There is no reason to favor C over C++ when extending a scripting language.
Yeah, it is expensive for a poor to try to live as middle-class. And it is stupid. Stupidity is always more expensive.

The advantage of being poor is that you're detached from all that useless goods, property, stuff and even people. Then you can move. You can live where life is better - some warmer and cheaper place - maybe some buddhist countries, but not California, of course.

Take a look at the Indian brahmins, Tibetan or buddhist monks - they are very poor, as poor as possible, but they are happy and healthy because they does not trying to catch some advertised illusion or broadcasted style of life.

The rule is very simple - spend less than you got. It means to avoid what you can't afford. If you have only one bag with some absolutely necessary things you can live in almost every place with warm climate and peaceful people.
I recently became aware that I was unable to review a movie with anything more profound than, "It held my attention for two hours." I've been actively seeking out movies that are considered great, and just engaging my brain a bit more while I watch them. It has significantly increased my appreciation for many movies. It's also meant I've noticed more flaws, but it's made the experience of movie-watching so much more enjoyable and meaningful, and not just the time-killer it used to be.

When I read the announcement this morning, it occurred to me that the reason I like AWS so much, and what separates them from other cloud offerings, is that they're doing stuff dev teams actually want and can use (not impenetrably complex tech we could use with some vendor consultancy). Import features like this are trivial for AWS to implement - but will be a step change for some customers.

Last generation vendors saying 'anyone can do what AWS are doing' is just crap. You can't buy the enthusiasm these guys have - and its not just one individual - if you talk to anyone from AWS (and they're often around nights/weekends to talk about stuff) they are in a different lane to the competition or vendors that should be the competition.
Oh that's a shame, I didn't know it had been cut.

I have to admit that I have never read Anderson, but I sincerely doubt that he even saw the long tail replacing the blockbuster as the article implies. They are the two sides of the same coin, and you can't really have one over another; the only thing that new technologies have provided is a way for a company to actually be profitable by focusing on the long tail part of the market.
I've rewritten Python programs in C++ and got close to the same line count, yet hugely better resource usage. You can't do that with C.

With C++ you often don't need to reach for a heavy and slow language. You'll do just as well for maybe a 2X development speed penalty.

I know you asked the question to Mahmud, but here is what I think.

To start with, Undergrad texts (the best I've found) to prepare you for Machine Learning.

Calculus (Strang) available free http://ocw.mit.edu/ans7870/resources/Strang/strangtext.htm

Linear Algebra(Strang) not free.

Probability( by Bertsekas a new edition just came out. expensive but VERY good).

Information Theory (also useful in ML) David McKay. freely available at http://www.inference.phy.cam.ac.uk/mackay/itprnn/book.html

Convex Optimizaton by Boyd. (free http://www.stanford.edu/~boyd/cvxbook/). Videos available on the Stanford site. http://see.stanford.edu/see/courses.aspx

Plenty of books at the graduate level - Spivak's Calculus and Rudin's Introduction to Functional Analysis should get you most of the way through mahmud's list of things to learn

After all these, you should be able to pick and choose for yourself. Enjoy!
To put it in computer science lingo: an ordered datatype is easier to search and sort.
I don't think it's the amount of information that we crave. Traditional japanese living spaces would compress well, yet they look like personal, interesting places to inhabit. Conversely, a messy manufactured home is information rich, but I don't think it would quench your 'thirst' in the same way.

I think it's meaning we crave, and if we can get it with a better signal to noise ratio, that's more peace of mind for us.

That said, the 'noise' in the shape and texture of natural materials compresses away as generic texture. I think we have evolved to interpret that effortlessly in hardware. The noise of a waterfall can give us peace while the noise of traffic usually has the opposite effect.

More interestingly, we can selectively turn off this mechanism to appreciate natural shapes and textures in their full depth. A tree can be very information rich if we direct our attention to it, while at the same time it's easy to filter it out as 'ok, tree here' without further anxiety. A landscape typically has a lot of information in it, but if we can find a pattern that summarizes its overall shape, its beauty just hits us as something really simple, without need for intense attention or effort in interpretation.

Something tells me that policies more like these would go a very long way toward encouraging greener housing in this country

Yes, but that would also result in people being able to build houses for $5,000 (plus one man-year of inexpert labor, granted), and there are a lot of people who would be discomfited by that, so I don't expect those policies to go anywhere.

Yeah yeah, I know, I know, it has everything to do with public safety and nothing to do with the fact that everything touching housing, from designing to building to selling, is controlled by guilds. (Guilds which could be replaced pretty much wholesale by recent immigrants or other dirt-cheap non-expert labor. After all, if a non-expert can snap together freaking Bag End in the English countryside, how much guild-approved expertise do you really need?)

So your criticism of Clojure is based upon unfounded assumptions about what the community will do in future? Maybe you should look at what libraries are being created before you leap to conclusions?

There are many Clojure libraries that attempt to reimplement existing Java libraries. For instance, Ring is a HTTP specification for Clojure that reimplements much of the functionality of Java servlets.
