That's always been my philosophy too.

Hadoop is a framework, not a library, so user applications need to link against the jars they need. That implies using CLASSPATH to locate them. Whether or not there is 1 jar or 100, the fact that there's no standard place to install

If you don't want the pip dependencies to "pollute the rest of the system," you can just use pip install with the --root option. Java's CLASSPATH causes enormous pain for end-users. Just read the Hadoop mailing list. T

In the example you gave, any compiler from the last 10 years would have given a warning message when converting the pointer to an int. Ignoring error messages is extremely, extremely bad practice. If you are still doing that, I suggest au

The problem was that this idea was a feature of a point-of-sale (POS) system, not a product.

There are a bunch of e-ink readers out there already that do well with PDFs. I have an e-reader made by PocketBook ( http://en.wikipedia.org/wiki/PocketBook_International ) which is 10.5 inches long and does PDF very w

Did you read the article? SF has been expensive for a long time. When adjusted for inflation, this isn't even the most expensive that it's been.

You know, there is more in the bay area than San Francisco. If you try living in Berkeley or Oakland for a few months, you will find that it isn't "a remote, suburban sprawl-y part of the Bay Area." It's only a half ho

You can always pass around pointers to immutable data structures which only implement read interfaces.

Is anyone here arguing in favor of colonialism? This is equivalent to comparing people who disagree with you to Hitler. Thanks for your "extensive academic thought," which I note you did not even bother to summarize here. I thi

Yeah, it sounds like he should just use a statically typed language. (yes, I am aware that types != contracts, but they're similar enough that my statement still stands)

Now that we are on the subject, what is one sane way to drastically reduce the need for locks and semaphores? Use actors like Erlang does. A class with a thread and a queue attached to it. Then avoid sharing data instead send messages. You

Most of gcc is still written in C. Only a tiny amount of new code is in C++. In my opinion, that's the worst of both worlds-- inconsistent code, plus C++ overheads. I work with some fairly recent version of both compilers-- gcc 4.7.2

by cmccabe 13y ago
Well, I like the clang error messages better than gcc's, and I use recent versions. And to refer to the major architectural differences between the two as something that could be bridged by a single "patch" is a little silly

OK, I admit it was a cheap shot. But I'm not the only one in the thread making it. And the quote is definitely bizarre. Can you explain how it's related to Perl? I agree that Perl has done a very good job with backwards compati

Maven isn't standardized. There are still a lot of projects that use Ant + Grail or Gradle. There's also OSGI, which is sort of yet another way to manage dependencies in Java. Maven doesn't prevent versioning issues from cr

You can't install a java tool-- any java tool-- just by a file copy. At minimum, you need to install the proper version of the JVM (different software may need different versions)-- that's at least 50 MB and maybe 100 these days.

Yes, you do have to keep your master clean. The version tagging thing is only intended to be used when you start depending on a new language feature not available in older versions of Go. For example, if your new code needs something that

Yeah, it's pretty bizarre. Was slashdot still relevant in 2005? Was perl? I feel like they both peaked right around the turn of the century.

I think what Go's subprocess stuff needs most is better examples. There aren't a lot of examples out there yet. For example, I saw one guy on StackOverflow use a complicated Reader thread to print a subprocess' output to st

One thing that annoyed me about both Python and Rubyis that the way things in the standard library worked changed from release to release in subtle, incompatible ways. I remember getting burned by a change in how iterating over characters

The safeguards for foreigners are much less than those for US citizens. For example, the NSA doesn't need to go through FISA court to spy on non-citizens. So if you store your data on a non-US server, you're probably just making

Yeah, I always seem to forget the exact details of Nagle (probably because every project I've worked on just turns it off). Write-write-read is the killer, I guess-- just doing a small write followed by a small read, or vice versa, sh

EDIT. OK, so. I ran this benchmark myself on an 8-core Xeon running Linux. 2.13 GHz, CentOS 6.2. Kernel was 2.6.32-220.el6.x86_64. 50 gigs of RAM. I got somewhere between 2.0 and 2.2 "milliseconds per ping" for Scala 2.9, and

I suppose it depends on how good you are at coming up with random file names. You could also use O_EXCL | O_CREAT to fail if the file already existed. The more I think about it, though, the worse this whole interface is starting to smell.
