I wrote an article that got posted on the O'Reilly Network. It sounds a little more huckster-ish than I'd like, but the tech does get explained pretty well. There's a link to the new beta 2 release of SwarmStream Public Edition at the bottom of the article.
Detecting Recently Used Words On the Fly
When writing I frequently find myself searching backward, either visually or using a reverse-find, to see if I've previously used the word that I've just used. Some words, say furthermore for example, just can't show up more than once per paragraph or two without looking overused.
I was thinking that if my editor/word-processor had a feature wherein all instances of the word I just typed were briefly highlighted it would allow me to notice awkward repeats without having to actively watch for them. Nothing terribly intrusive, mind you, but just a quick flicker of highlight while I type.
Obscuring MoinMoin Wiki Referrers
When you click on a link in your browser to go to a new web page your browser sends along a Referrer: header, which tells the owner of the site that's been linked to the URL of the site where the link was found. It's a nice little feature that helps website creators know who is linking to them. Referrer headers are easily faked or disabled, but in general most people don't bother, because there's generally no harm in telling a website owner who told you about their site.
Ringback Tones Made Less Evil
Foreign cell phone services have had a feature for awhile called Ringback Tones which allows you replace the normal ringing sound that callers hear while they're waiting for you to answer with a short audio clip. This isn't the annoying ring that the people near you hear until you answer your phone, but the even more annoying ring that the people calling you will hear directly in their ear. The feature has come to the US recently, and my cell phone provider, T-Mobile, calls its offering Caller Tunes.
Designing a Beer Temperature Experiment
I've repeatedly encountered the statement, always presented as fact, that if you chill beer, let it return to room temperature, and then chill it again you will have affected in it a degradation of quality. This has always seemed like nonsense to me for a few different reasons, chief among them that surely this chill/warm cycle happened repeatedly during transport and retail.
As a beer snob, I generally drink beers imported from Europe. These are shipped to the US in huge container ships across the icy North Atlantic. They're then shipped in semi trucks to Minnesota. Next they're stored at distribution centers, in retail warehouses, and on the sales floor (or in the beer cooler) Surely in one season or another the temperature variance during those many legs and stops constitutes at least one cooling/warming cycle.
SwarmStream Public Edition
My latest project for Onion Networks has just been released: it's a first beta release of SwarmStream Public Edition, a completely free Java protocol handler plug-in that transparently augments any HTTP data transfer with caching, automatic fail-over, automatic resume, and wide-area file transfer acceleration.
SwarmStream Public Edition is a scaled-down version of our commercially-licensable SwarmStream SDK. Both systems are designed to provide networked applications with high levels of reliability and performance by combining commodity servers and cheap bandwidth with intelligent networking software.
Who Wins ‘Click Here’
The w3c, the nominal leader of web standards, has a recommendation against using click here or here as the text for links on web pages. In addition to the good reasons they provide, there's google to consider. Google assigns page rank to web sites based on, among a great many other things, the text used in links to that page. When you link to https://ry4an.org/ with ry4an as the link text I get more closely associated with the term ry4an in google's rankings. However, when you link to a page using generic link text, such as here or click here you're not really helping anyone to find anything any easier.
Better Random Subject Lines
Earlier I talked about generating random Subject lines for emails. I settled on something that looked like Subject: Your email (1024) . Those were fine, but got dull quickly. By switching the procmail rules to look like:
:0 fhw * ^Subject:[\ ]*$ |formail -i "Subject: RANDOM: $(fortune -n 65 -s | perl -pe 's/\s+/ /g')" :0 fhw * !^Subject: |formail -i "Subject: RANDOM: $(fortune -n 65 -s | perl -pe 's/\s+/ /g')"
I'm now able to get random subject lines with a little more meat to them. They come out looking like: RANDOM: The coast was clear. -- Lope de Vega
Jetty with Large File Support
Jetty is a great Java servlet container and web server. It's fully embeddable and at OnionNetworks we've used it in many of our products. It, however, has the same 2GiB file size limit that a lot of software does. This limit comes from using a 32 bit wide value to store file size yeilding a 4GiB (unsigned) or 2GiB (signed) maximum, and represents a real design gaff on the part of the developers.
Adding a Subject with Procmail
Lately I've been corresponding a great deal with someone who doesn't elect to use the Subject: line in emails. When responding to this emails my mail application, mutt, uses the Subject line: re: your mail. Mutt also groups conversations into threads using (among other things) the Subject line. So every reply to every person who has sent a message with a blank subject line gets grouped into a single thread when they, in fact, have nothing to do with one another.
