Representative Line: Listing Off the Problems

The Daily WTF
3 months 1 week ago

Today, Mike sends us a Java Representative Line that is, well, very representative. The line itself isn't inherently a WTF, but it points to WTFs behind it. It's an omen of WTFs, a harbinger.

ArrayList[] data = new ArrayList[dataList.size()];

dataList is an array list. This line creates an array of arraylists, equal in length to dataList. Why? It's hard to say for certain, but the whiff I get off it is that this is an attempt to do "object orientation by array(list)s." Each entry in dataList is some sort of object. They're going to convert each object in dataList into an arraylist of values. This also either is old enough to predate Java generics (which is its own WTF), or explicitly wants a non-generic version so that it can do this munging of values into an array.

Mike provided no further explanation, so that's all speculation. But what is true is that when I see a line like that, my programmer sense starting tingling- something is wrong, even if I don't quite know what.

Quarter of UK University Physics Departments At Risk of Closing, Survey Finds

Slashdot
3 months 1 week ago
An anonymous reader quotes a report from The Guardian: The heads of UK physics departments say their subject is facing a national crisis as one in four warns that their university departments are in danger of closing because of funding pressures. In an anonymous survey of department heads by the Institute of Physics (IoP), 26% said they faced potential closure of their department within the next two years, while 60% said they expected courses to be reduced. Four out of five departments said they were making staff cuts, and many were considering mergers or consolidation in what senior physicists described as a severe threat to the UK's future success. [...] To avoid "irreversible damage", the IoP is asking for immediate government action including funding to support existing labs and research facilities, as well as setting up an "early warning system" to monitor departments at risk of closure, and reduce pressures affecting international student recruitment. In the longer term it is calling for radical reforms in higher education funding to allow universities to meet the full costs of teaching nationally important subjects such as physics. Sir Keith Burnett, the IoP's president and a former chair of physics at Oxford University, said: "While we understand the pressures on public finances, it would be negligent not to sound the alarm for a national capability fundamental to our wellbeing, competitiveness and the defense of the realm. "We are walking towards a cliff edge but there is still time to avert a crisis which would lead not just to lost potential but to many physics departments shutting down altogether. Physics researchers and talented physics students are our future but if action isn't taken now to stabilize, strengthen and sustain one of our greatest national assets, we risk leaving them high and dry." Thomas said the erosion in value of domestic tuition fees and falling numbers of international students were behind the financial pressures, with smaller physics departments the most at risk. "What that means is we will get more and more concentration of where physics is being taught and lose geographical distribution. That goes against aims of widening participation and means some disadvantaged groups will miss out on opportunities to study physics, and it's important that we recognize that," Thomas said.
