I’ve talked before about the value of a good REPL (scroll down to “The REPL in .NET”). Unfortunately, the programming language I write the most code in, C, lacks one. Or at least, it used to. The aptly named C REPL provides a REPL for C. Their trick: compile a DLL for each line of code, then load it into a new process. Presto: instant, portable interactive C.

I’m generally quite paranoid when it comes to server security—doubly so because I’m no guru at it—so I tend to take a shotgun approach. The virtual server running bit qua bit has a restrictive firewall setup, has root disabled, only allows secure IMAP/POP/SMTP, disallows password login through SSH, and mails me daily security audits, among other things. I also monitor Debian’s security-announce list like a hawk. (If you’re the sysadmin for a Debian server and you’re not on that list, sign up.…

I was pleasantly surprised today to discover Squeak by Example, an open-source book on writing programs with Squeak Smalltalk. If you want the bleeding-edge version of the book right now, you’ll need Subversion and an up-to-date LaTeX installation, but a physical book and online PDF are also available if you don’t want to muck with all that. Combined with Stéphane Ducasse’s compilation of free Smalltalk books, I don’t think any Smalltalk neophyte should be wanting for learning material.

From Slashdot, which is slowly redeeming itself, comes a link to Microsoft admitting that it bribed members of the Swedish ISO committee to vote for OOXML. Unsurprisingly, the Swedish ISO committee just voided its own vote. Due to time crunch, they will not be casting a vote at all in the Open XML ratification process. I find it depressing but predictable that I’m unsurprised.

I think that the Wall Street Journal does a fairly good job covering technology from a consumer’s perspective, but I feel that they struggle whenever they try to cover more industry-focused issues, making outright mistakes and failing to understand what in the debate is actually important, which leads them to follow up (or fail to) on the wrong points. Today was no exception: in an article entitled “‘Office’ Wars,” they attempted to cover the politics revolving around Microsoft’s efforts to get…

In my previous article, I discussed some alternatives to C++ for systems programming. Today, I want to provide an example of why you might care. Tyler and I recently debated rewriting Fog Creek Copilot in Qt, a powerful, high-level, cross-platform C++ framework. The idea came to us when we started discussing the implications of maintaining four helper applications (Windows Helper, Windows Helpee, Mac Helper, Mac Helpee), each of which shares depressingly little code with the others. Because Qt…

As you may or may not know, ANSI is trying to push a new C++ standard out the door called C++0x (which those of you who know C may find amusing, since you can read it “C++ Hex”). C++0x’s primary goal is to take C++'s already horribly convoluted syntax and make it even worse. Looking at a summary of C++0x’s additions, for example, we come across the concept of rvalue references, expressed as int &&x. With this move, C++ now has a bizarre hybrid of pointers and handles that solves a legitimate…

I don’t know why, but recently, as my love of really low-level hardware and my desire for low-power, high-performance computing has increased, I’ve been researching all the old, famous CPUs and operating systems. I started over what I swore was going to be a computer-free vacation by delving into programming in assembly for 680x0 Macintoshes (during which time I fell in love with 68k assembly), then explored ARM chips, and finally somehow or another ended up at 4:30 AM on a Sunday working on an…

A couple of weeks ago, I purchased a Dell Inspiron 6400 to replace my old and quite literally beat-up PowerBook G4 Titanium. The PowerBook is slow, its screen is damaged, its paint’s chipping off, its wireless has never been especially good, and nowadays, I find myself politely wondering when the hard disk is going to simply keel over. It’s done an amazing job over the last six years, but I felt that it was time to let it take a much-needed rest. Because I’ve been a diehard Mac user for nearly…

I’m a diehard Emacs user. When I first get into the office, I fire up Emacs, then check my mail in Emacs, then update all of my source files using either the built-in Subversion bindings or a Cygwin shell via Emacs, and finally get down to coding for the day in Emacs. Windows and Mac OS X at times feel like just the kernel that allows me to run Emacs. Productivity-wise, that’s actually a great thing. My work environment is basically identical no matter what machine I’m on, enabling me to focus…
