Mud, most of the tunnel boring machines dig through mud. Mud does not need any more fracturing, its quite easy to dig through as is. Its really hard to dig tunnels in it because it likes to collapse on top of you. It's like why do you

This is for 2006. And before we pile the hate on java do consider what still applies. And what of it applies to your language of choice.

I think it is really cool to see the promises of Truffle starting to get delivered! What is really cool is that this won't just be for Ruby, but also other languages such as JS and R.

With java scalar replacement (possible from escape analysis/partial or not) calling new Point(x,y) in a hot loop does not allocate an object on heap at all (or even the stack) unless it escapes. In the newer JITs that escaping allocati

Just use one of the other JVM's that have GC that are latency optimised such as Zing from Azul, Metronome from IBM or OpenJDK with Shendoah from RedHat. The power of Java is that there is more than one JVM and that can really save you

PyPy seems to be the one real contender for fast Python. ZipPy was super interesting academic work but unfortunately does not seem to be going anywhere. I am not surprised that a silicon valley company stopped sponsoring this. 3 years of si

I like the idea of the Game, as long as you see it as a game ;) For real performance comparisons I think the rules are not really followed all that well. Many tests end up being how quickly can you execute tuned assembly or use memory arena

It is 15" screen wise. Lighter than a 2009-2013 13" MacBookPro.

Sorry I was confused between your experience and the opening post which was moving from Scala to GO. So I assumed you were working for Movio and used their numbers. Therefore my post does not make any sense :) Then it was a Java to GO move.

Offence! the US army has an unequaled capacity for actually running an offence war (or 2) anywhere in the world. No other military has even a fraction of that capacity. Basically the US really needs defence from Canada and Mexico, no one el

Not an expert but this is the system in general The Swiss system is somewhat fixed prices (TarMED etc) for care provided. This changes every so often. However, hospitals and doctors do charge for extras not related to primary care e.g. priv

As this is the 3rd language in your code base, 1st there was java, then there was Scala and now GO. I do hope all Scala code is gone by now! I assume this decision and investment was extremely well supported, but that is not obvious from yo

This is the execution layer, i.e. how is that Scala program turned into machine code. You can make a Haskell implemented using Truffle. Or Rust etc... Haskell, defines the semantics of a program, while truffle turns that semantics into exec

Yes and france depends on other countries for its incapability to quickly vary production. In other words the nuclear fleet of France has a significantly higher capacity factor than the average demand of the french grid because it can push

That is an unreasonable backup requirement. It is not a backup requirement for any single nuclear power plant either. Those can be taken out by snow storms too (single pylon failure on a line). Or just a refueling stop, which are quite comm

Just to point something out regarding nuclear. The announced cost overrun at Vogtle of 3 Billion USD, would pay for 7GwH of battery storage at tesla powerwall retail prices of 5500 USD per 14 KwH. 3 billion / 5500 = 545454 545454 * 14

Yes, java Sucks. But in many real and very important ways it sucks less than any of the alternatives. Especially considering the age of the language, and how backwards compatible it has been over the last 12 years. Sure the eco system went

My thinking was for this C return (num / num2) * num2; Where the division happens first. That is what I get for thinking about this before coffee.

by jerven 10y ago
Really cool, it surprised me to see even trivial code give very different results in gcc,icc and clang. int retNum(int num, int num2) { return (num * num2)/num; } gives this in clang retNum(int, int): # @retNum(i

We have one windows laptop for banking reasons. It is not a performance beast by any means. But whenever we want to do any banking we spend an hour waiting for the upgrade dance to complete. That is not a real problem, but the fact that you

Runtime loading of code by frameworks leads to Factory objects. e.g. database drivers. The only factory factory I know of is in the Spring runtime dependency injection framework.

Practical experience in such an institute providing such data. FTP servers for files just run, http servers tend to do more things than just serving files. This could be separated out of course but in _practice_ they aren't. Setting up

From the perspective of the student S3 over university wifi is not "better" than local USB2 hard drives. It actually is a risk budget wise.

To be honest, you should probably look at their RDF dumps if you are from a CS background or you will end up in Ensembls Perl/MySQL swamp.

Yeah, but in practice ranged GETs and HTTP servers are more likely to be down than the FTP servers.
