Harwell Dekatron revived as the world’s oldest working, original digital computer

Over 60 years since the first digital computers switched on, the chances of seeing one of these pioneers in action have grown incredibly slim as time (and recycling) takes its toll. Take a visit to Britain’s National Museum of Computing in Bletchley Park as of today, however, and you’ll see one working. A finished 3-year restoration effort lets the Harwell Dekatron — at one point renamed the Wolverhampton Instrument for Teaching Computation from Harwell, or WITCH — claim the title of the world’s oldest functional digital computer still using its original design. Aside from its room-filling dimensions, the 1951-era mainframe may be worth the trip just for recalling a time when there were no hard and fast rules in computing: the Dekatron operates in its namesake decimal system, not binary, and puts most of its components on full display. The computer is part of the regular exhibit lineup and should be easy to see; the daunting part may be realizing that virtually any chip in a 2012 smartphone could outmuscle the Dekatron without breaking a sweat.

Firefox 17 heads out of beta, officially drops support for OS X 10.5

We’ve just seen an update to Firefox for Android , but that’s not the only revision that Mozilla has had in the works. Today also sees the release of version 17 of the desktop browser, which brings with it a number of changes and one noticeable omission. The latter is a lack of support for Mac OS X 10.5 (a.k.a. Leopard), which Mozilla first announced last month — those on Leopard can of course continue to use Firefox 16, they just won’t receive any updates. Otherwise, you can expect a new “Awesome Bar” with larger icons, more than 20 promised performance improvements and a new click-to-play functionality for dealing with outdated or potentially vulnerable plug-ins. Also receiving the bump to version 17 is the Extended Support Release (or ESR) version of the browser, which disables the automatic updating to cause less headaches for those dealing with mass deployments. You can find the full change log at the source link below. Update: As TechCrunch notes , version 17 also adds the new Social API to Firefox, although Facebook is the only site to take advantage of it so far — it now lets you add Messenger to the browser’s sidebar.
