If you're thinking of operating in the USA, you should read up on Communications Assistance for Law Enforcement (CALEA). CALEA pretty much requires that you be able to associate a name with any IP on your network, so you're going to have a

The GPL generally doesn't block a proprietary program from calling an open source one via a shell pipe. If it did, most commercial software running on a Linux system would run afoul of the GPL licensing of the core system commands (cp, ls,

Forgive me if I'm just out of date here, but last time I checked, REE offered something like a 30% memory savings per forked worker. By my math (Workers_ree = Workers_mri / 0.7) that gives you something like a 1.4X increase in number of ava

Why exactly do you assume that a credit card reader is a "closed box that is obviously provided by a bank"? I've implemented point-of-sale systems before, and lemme tell you, there's nothing magical about a magstripe reader, a microcontroll
215.
by rcoder 17y ago
Magstripe readers have been within the reach of any reasonably-clever fraudster for a long time . Attaching them to an iPhone and using audio modulation for the signal doesn't magically open the floodgates to card skimming and duplication.

When I worked on a sizable JRuby/Rails codebase, our team had a hybrid approach: ephemeral jobs (rake tasks, migrations, autospec) all ran under MRI, while long-lived processes (app servers, CI/acceptance test runs) ran in JRuby. That gave

It's a network security tool used for exploiting security holes in Windows systems in order to inject a remote control payload. It does have white-hat utility, but my sense is that it's mostly used for grey and black-hat activities. Unlike

Once you have a Javascript environment, it's not a large jump to emulate a minimal DOM -- see env.js, for example: http://ejohn.org/blog/bringing-the-browser-to-the-server/ With a stub DOM and Javascript interpreter, you can pass generate

Have you heard of a little something called Fair Use? If you were to modify one of Apple's system utilities and then distribute it, you could easily run afoul of copyright. Simply making a local modification in-place, however, is no more

At minimum, the fact that the core functionality is available as open source gives me some additional confidence in the platform's long-term viability: http://www.dimdim.com/opensource/dimdim_open_source_communit... Even if the company go

How about this: install Debian, 'apt-get install kvm' (okay, you'll probably have to run that through module-assistant, but still, it's only a few more presses of 'Enter' away), then run 'qemu-system-x86_64 haiku.img -m 2048'. Voila! Linux

The reasons to stick with DHTML/JS as a "thick client" development platform are simple: decent, free development tools, the ability to interpose proxies and application middleware between the client and server transparently, and a very, ver

Since the pickle module doesn't marshal many types of stateful objects (filehandles, functions, etc.), I'm not sure it's fair to describe it as a means of saving the "state of the Python interpreter". It really just serves to save a compact

by rcoder 17y ago
I guess it was, "no, it shouldn't be, except that the pickle module is broken by design." I.e., data structure parsing should not require a Turing-complete language. If it does, your serialization format is broken. But yeah, I can see the i

YAML is strictly a superset of JSON in its expressiveness, since it allows tagging of serialized objects with a type name. JSON reduces everything to maps, arrays, and scalars, so any type information has to be encoded in (or inferred from)

No. Proving termination for programs written in models less powerful than a Turing machine does not require you to solve the halting problem. Programs using primitive recursion, finite automata, and regular expressions, for example, can all

Since it sounds like a number of people are maintaining local patches to this library, might it make sense to fork it on GitHub to try to get some additional contributors onboard?

I'm not sure that I 100% buy the claim that this is a new form of web navigation -- knowledge base, ticket-tracking, and e-commerce tools have had numeric quick-jump features for years. It is an interesting approach to more traditional te

_why has always been an unusual guy. He has always prized his pseudonymity online, so I'm honestly not entirely shocked to see that he has decided to simply pack it up and move on. It's a sad day for all of us, but I hope and trust that he

You're generally right about complex specification and verification being popular in the defense and aerospace industries. However, I think that you may be mistaking a secure microkernel for a real-time one. There are hard real-time var

Java bytecode is Turing-complete, so there's nothing explicitly preventing you from implementing many of the advanced features of C# atop the JVM. As the OP stated, alternate languages running on the JVM (such as Scala) already do this. The
