Yet Another Reason to Encrypt Files in Dropbox

As I’ve written many many times, if you’re storing anything in Dropbox that you wouldn’t want to see published in the New York Times then you better encrypt it. Here’s yet another reason to do so.

Package Management Across Machines

Daniel Szmulewicz has an interesting post up on his blog about managing Emacs packages when you have multiple machines that you want to keep configured identically. He went through the usual cycle of solutions: First, he managed it by simply copying over his init.d to each of the machines and then loading whatever packages he needed from ELPA or other sources. Then he put his .emacs.d under version control but he found that objectionable because he was putting external code under version control. Next he wrote a bit of Elisp to load a list of packages, put it in his init.d and put just that under version control.

That’s where most of us would have stopped but he asked himself how he could also automate deleting packages. He found a very nice solution using el-get that handles both adding and deleting packages according the one simple list in his init.el. If you’re trying to maintain the same Emacs configuration on more than one machine, you may find his solution useful. Definitely worth a look.

Emacs Redux

Bozhidar Batsov has started a new blog, Emacs Redux, that is dedicated to tips and techniques to make the Emacs experience more productive and enjoyable. So far, I like what I see.

One of the tips from the first day of the blog is how to mark variables and functions void. This is something I often want to do when I’m experimenting with some Elisp and want to get rid of it when I’m done so that it doesn’t take up space. (I know, I know, I’m OCD but remember that I come from the time when EMACS == Eventually Mallocs All of Core Storage still had traction.) You do that with makunbound and fmakunbound as Batsov explains here.

If you’re an Emacs user you should give this blog a look. I’m looking forward to reading future posts. As far as I can see, he doesn’t have RSS set up yet but I’m hoping that happens—I wouldn’t want to miss out on any tips.

Afterword: I was able to subscribe the blog to Reeder, my RSS reader, by just specifying http://emacsredux.com. Users of other RSS readers report having to add http://emacsredux.com/atom.xml to get it to work.

Sacha Chua Chats With Carsten Dominik

The tireless Sacha Chua is on a roll with another video chat about Emacs. This time it’s with Carsten Dominik, the creator of the essential Org mode. Org mode has become so important that many newcomers are taking up Emacs specifically to get it.

This is, by far, Chua’s most engaging chat so far. Dominik is a natural story teller and the two of them are clearly at ease and having a lot of fun. Dominik talks about his early start with MicroEmacs before he graduated to the real thing and how he’s always made little tweaks and add ons to Emacs even before Org. He gives a real sense of how Org mode grew organically, often surprising even him.

It turns out that Dominik follows Chua’s blog and he speaks highly of it and of Magnar Sveen’s Emacs Rocks! videos. He comes across as someone you’d love to spend a few hours with just chatting. I really recommend this video. It’s about 50 minutes so you’ll need to block out some time but I’m sure you’ll find it worthwhile.

The Wages of Sin

Well, not sin really. More like the consequences of ill considered decisions. As we all know by now, Google has decided to terminate their Google Reader service. On the face of it, the decision doesn’t appear particularly controversial. The service, while used by many, is by no means wildly popular and with the decline of RSS has become less so. Google has never found a way to monetize it so why keep spending resources on it?

The answer to that is found in the nature of the Google Reader constituency. By and large it is used (and loved) by nerds. That might seem like an even better reason to ax it except that on the Internet, it’s the nerds who are the influencers. They are the ones that the technically naive come to for advice on what hardware they should buy and what services they should sign up for. If you’re trying to make money on the Internet, you ignore them at your peril.

You’d think that Google, more than most, would understand this yet here they are not only ignoring the nerds but doing something they find deeply offensive. So what? Well, Google is launching a new service, Google Keep, that is obviously meant to compete with the popular Evernote. Suppose the nerds were to turn against the new service and advice people to avoid it. What arguments would they use? The answer writes itself doesn’t it? Depend on this service and sooner or later Google will retire it and all your notes will be lost. Would the technical community do that? Why yes. Yes, they would.

Maybe in the end it won’t matter but Google was first embraced by the nerds who served as evangelists to the laity. If the technical community does play a roll in causing the failure of Keep and future Google initiatives Google will have no one but themselves to blame and the nerds will enjoy a moment of schadenfreude.

For my part, I’ve upgraded my Evernote account to premium even though I don’t come close to exceeding the free account limits. I think of it as a way to help preserve my notes and to ensure that Google doesn’t crush Evernote.

What to Do About the Worst Law

Over at the New Yorker, Tim Wu writes about Fixing the Worst Law in Technology. That law is, of course, the Computer Fraud and Abuse Act. CFAA was the vehicle that federal prosecutors used to threaten Aaron Swartz with decades in prison and millions of dollars in fines for what, at the end of the day, was violating JSTOR’s terms of service. Those threats are widely believed to have precipitated Swartz’s suicide but far from being chastened, prosecutors are busy charging others with similar trivial violations carrying equally severe penalties.

None of this is news to the informed geek and certainly the Irreal readership is aware of the issues. What’s significant about the New Yorker article is that it’s in the New Yorker. The magazine is hardly a hotbed of technology news and not a place where one would expect to find a large contingent of geeks hanging out. It is, in short, as mainstream as a magazine can be. Thus, it’s significant that they are covering this issue and bringing it to the attention of people who might never have heard of it otherwise.

The article is sympathetic to the movement to get the CFAA changed and unlike many publications—mainstream and technical—gets the facts of the Swartz case correct. Still, Wu is pessimistic about Congress making any meaningful changes, Zoe Lofgren’s bill notwithstanding. He believes that the best hope for change is that President Obama will reform it administratively. Not that encouraging but at least the word is getting out beyond the technical community.

The article is well written and worth a read if only because it won’t tell you that Swartz “hacked” into some site and stole a bunch of papers. Go on over and take a look.

Emacs Rocks! 14

At last! Magnar Sveen has just posted Episode 14 of Emacs Rocks!. This time it’s about paredit, an extremely useful but often confusing minor mode for dealing with S-expressions. Like Sveen, I also had a hard time getting used to paredit but once you figure it out you won’t want to live without it.

Sveen makes a helpful observation: paredit is not about adding and deleting text; it’s about manipulating the tree that constitutes a Lisp program. It tries to maintain a valid tree at all times. I found that the key to making things work—as detailed in the above linked post from my old blog—is understanding slurpage and barfage.

Sveen covers that as well as several other really useful tricks. As usual, the video is short (3 minutes 39 seconds) but packed incredibly densely with information. Get over there and watch it.
