Yes. This approach works. I used it when I actually did work in a proprietary language which had no usable objects, but did have half-decent lambdas. Most people did not understand or use them at all, but one new guy with a Java background

In my past life as an "enterprise" programmer, most people at best paid lip service to doing the "Right Thing." Most code I saw was incredibly bad, written by programmers who knew they would switch groups or companies, or go into management

Good post, but I wish it addressed the accessibility argument a bit more thoroughly. Although in fairness, it does not seem that Mockingbird is terribly useful for visually-disabled users in any case.

Thanks, I didn't know that! With regard to the non-geographical "timezone" concept, is that what the time zone ID string concept "Europe/London" aims to solve (along with historical and assumed future rules specifying time changes)? I alway

Great article. The author suggests saving time in two formats, (1) UTC and (2) local date-time with a geographical time zone. The app would then pick the right one to use depending on context. BTW, let me take the opportunity to praise the

I once read that anyone who actually finds a SHA256 collision should publish it in a paper. SHA256 collisions are supposed to be the just shy of impossible to find (you know, the whole old trope of millions of machines millions of times fas

Quite a few ways. 1. Start with M-x rgrep, it may do everything you need. 2. If not, M-x find-grep lets you run arbitrary grep commands. You may wish to customize grep-find-command to some reasonable default, e.g., mine: (setq grep-fi

loop-recur has its good points, but it has its limitations, too. To wit, recur is not allowed inside a catch or finally form. (At least in Clojure 1.0.0.) By extension, this precludes the use of for, dotimes, doseq, and any other macro whic

I'd like to (slightly) challenge #8: it seems to me that Dropbox is a counterexample. The Dropbox guys took quite a long time and their first release was quite polished. Not perfect, certainly, but way, way ahead of just minimally functiona

Active: Cupboard ( http://github.com/gcv/cupboard ), an embedded database for Clojure. I wrote and open-sourced it, I guess that's about as active as it gets. :) Patcher: Samba. I work with it extensively, so I look at its code all the time

Doesn't the documentation have to then become as rigorous as code --- effectively a high-level language in its own right? So writing the documentation becomes, well, just like writing a program without testing it as you go, without benefit

Try turning on the keyboard shortcuts and learning them. I can't imagine wasting time hunting for 'c'ompose, or 'C'ompose for a new window. Some are a little odd ('#' for delete and 'e' for archive), but I think there's a Lab you can turn o

Chiming in to the chorus: what do you use for that type of programming? How does it support the kinds of formal proofs you mentioned? Although I have proven the correctness of some simple code, I have found that the proof and the code can d

A lot of interesting and bold claims. Has anyone played with this product? Does it actually work well?

What about network shares?

by gcv 17y ago
Possibly. I didn't find this trick until recently, and I switched to Emacs 23 pretty much right after it came out.

by gcv 17y ago
No, I mean reverse incremental search. M-r doesn't show matches as you type (at least not with Emacs 23 and my setup), but C-r does.
562.
by gcv 17y ago
After years of using Emacs, I only just discovered that incremental search works within the ordinary find-file (C-x C-f) function. Try it: C-x C-f, then C-r, and search for a piece of a filename you opened in the recent past. Try C-M-r, and

Thank you for posting this. Ledger looks fantastic. Not sure yet how I can use its files to give information to an accountant, but I'm sure I'll achieve enlightenment after learning more about it. One more cool thing: look at the TODO file

Good question. I can think of two tasks for which I routinely use the shell, and wouldn't really prefer one of the newer scripting languages: 1. Customizing my interactive shell, although I personally favor zsh over bash. I write shell func

I wonder if that's a generational thing. When I hear "nuclear," I tend to hear "exciting source of relatively clean renewable energy." Of course I know about weaponry, and I know about Chernobyl, better than most, but I also hold that atomi

Indeed. I'd buy this instantly if it provided an iPhone-friendly interface for reading the discussion, but I can't tell from the screenshots. Also, if there is a story view --- reasonably sized up-down voting arrows alone would make it wort

The author says he spent two weeks setting up Eclipse to work with OCaml; he's a serious productivity maven. It would have taken less time to learn enough vi or Emacs to get by, their OCaml modes, and would have benefitted him in the long r

Samba uses fork to create new instances of itself to handle each connected user, and I am often grateful that it does that instead of using threads. Since each user has a separate process, something going wrong inside the process means that
