I had a couple tweets this week that were fairly popular. The first was a pun on the musical Hamilton and the Hamiltonian from physics. The former is about Alexander Hamilton (1755–1804) and the latter is named after William Rowan Hamilton (1805–1865).
I’m making a couple changes to my Twitter accounts.
First, I’m winding down @PerlRegex. I’ll stop tweeting there when my scheduled tweets run out. I suggest that everyone who has been following @PerlRegex start following @RegexTip instead. The latter is more general, but is mostly compatible with Perl.
Second, I’m reviving my @DSP_Fact. I stopped tweeting there a couple years ago, but I’d like to start posting there again. This time it’s going to be a little broader. I intend to include some material on acoustics, Fourier analysis (continuous and discrete), and maybe some other related material.
Periodically someone on Twitter will suggest that one of my Twitter accounts is a bot. Others will reply in the second person plural, suggesting that there’s a group of people behind one of the accounts. These accounts aren’t run by a bot or a committee, just me.
I do use software to schedule my tweets in advance. Most of the tweets from my personal account are live. Most of the tweets from my topic accounts are scheduled, though some are live. All replies are manual, not automated, and I don’t scrape content from anywhere.
Occasionally I read the responses to these accounts and sometimes I reply. But with over half a million followers (total, not unique) I don’t try to keep up with all the responses. If you’d like to contact me, you can do so here. That I do keep up with.
Twitter once provided RSS feeds for all Twitter accounts. They no longer provide this service. However, third parties can create RSS feeds from the content of Twitter accounts. BazQux has done this for my daily tip accounts, so you can subscribe to any of my accounts via RSS using the feeds linked to below.
If you would like to subscribe to more Twitter accounts via RSS, you could subscribe to the BazQux service and create a custom RSS feed for whatever Twitter, Google+, or Facebook accounts you’d like to follow.
I’ve started a new Twitter account @PerlRegex for Perl regular expressions. My original account, @RegexTip, is for regular expressions in general and doesn’t go into much detail regarding any particular implementation. @PerlRegex goes into the specifics of regular expressions in Perl.
Why specifically Perl regular expressions? Because Perl has the most powerful support for regular expressions (strictly speaking, “pattern matching.”) Other languages offer “Perl compatible” regular expressions, though the degree of compatibility varies and is always less than complete.
I imagine more people have ruled England than have mastered the whole of the Perl language. But it’s possible to use Perl for regular expression processing without learning too much of the wider language.
You can create an RSS feed for a Twitter account at RSS4Twitter, though they’re so overloaded that it might not work. You could also use BazQux RSS reader or try some of the alternatives mentioned in the comments here.
I’m planning to wind down three of my Twitter accounts: ShortcutKeyTip, MusicTheoryTip, and DSP_fact. When the scheduled tweets for these three accounts run out, I won’t post new ones.
On the other hand, I may start a new account. I have a topic in mind, but I don’t know how hard it’ll be to say interesting things about it in 140 characters. If I start a new account I’ll announce it here.
Right now I have 15 accounts. If I close three, I’ll still have a dozen, a baker’s dozen if I add a new account.
Update (August 11, 2013): I decided to start the new account I alluded to in this post: NetworkFact, devoted to networks, graphs, and related topics.
