Perl regex twitter account

Posted on by John

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.

Update: I’ve stopped posting to this account. Here’s a list of my current accounts.

New Twitter account for networks

Posted on by John

As I mentioned a few days ago, I’m winding down three of my Twitter accounts.

But I have started a new one: NetworkFact. This account has tweets about graph theory, analysis of large networks, etc.

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.

Twitter account turnover

Posted on by John

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.

How to subscribe to a Twitter account via RSS now

Posted on by John

Twitter turned off their RSS support last month. This page gives several ways to create new RSS feeds for Twitter accounts.

Update (October 27, 2014): Here is a cost-free and ad-free Android app that is an RSS feed generator for Twitter.

Update (April 25, 2015): Here is a list of RSS feeds for each of my Twitter accounts, hosted by BazQux.

Update (February 6, 2017): Subscribing to Twitter via RSS is a losing battle. I’ve deleted the rest of this post because it doesn’t work anymore.

New Twitter accounts for DSP and music theory

Posted on by John

I’ve started two new Twitter accounts this week: @DSP_fact and @MusicTheoryTip.

DSP_fact is for DSP, digital signal processing: filters, Fourier analysis, convolution, sampling, wavelets, etc.

MusicTheoryTip is for basic music theory with a little bias toward jazz. It’ll tweet about harmony, scales, tuning, notation, etc.

Here’s a full list of my 15 daily tip twitter accounts.

If you’re interested in one of these accounts but don’t use Twitter, you can subscribe to a Twitter account via RSS just as you’d subscribe to a blog.

If you’re using Google Reader to subscribe to RSS feeds, you’ll need to switch to something else by July 1. Here are 18 alternatives.
