Python Metaprogramming Decorators Make Magic Easy

Each Python version has added slightly different wrinkles to the way you accomplish metaprogramming tricks.

Decorators modify the function or method that is defined immediately after the decorator.

What's up with the annual Desktop Linux Summit?

Some folks who like to plan ahead are wondering if Linspire is going to host its Desktop Linux Summit this spring in San Diego, as it has for the past four years. It looks like we'll have to wait a bit longer to find out. By many accounts, last year's April confab at the Manchester Grand Hyatt was a big success, with nearly 1,000 participants causing a few standing-room-only crowds at some presentations.

What makes a 5GL?

From time to time vendors in the application development space have claimed 5GL (5th generation language) capabilities. If you think about this for a moment you will realise that this can't be true. The idea of GLs is that each is an abstraction of the former, so we had machine code (on which I cut my teeth as a developer); assembler; third generation languages such as COBOL, Java, C++ and so forth; and finally 4GLs (now sometimes referred to as ABLs-advanced business languages-as 4GL seems to be out of fashion).

Cox's DRM patent less than meets the eye

On Monday, Slashdot reported that legendary Linux kernel developer Alan Cox filed a patent application in June 2005 related to digital rights management technology.

The NEPSI Challenge: Who Gets the Data?

The National E Prescribing Patient Safety Initiative, press release here is an e-prescribing juggernaut aimed at providing 'free' e-prescribing for all doctors. '...The challenge, according to the eHealth Initiative, is that fewer than 1 in 5 of the nation’s practicing physicians currently process prescriptions electronically. Studies indicate that most physicians have been reluctant to adopt electronic prescribing largely because of the cost of the systems, and a perception that the technology requires too much time to learn and install. NEPSI will help address those barriers by providing physicians simple, safe and secure electronic prescribing at no cost...' This initiative raises a number of questions currently not answered: Who gets the e-prescribing data? Is this really free? What is in it for Allscripts?

Study finds open source key to European ICT competitiveness

eHealth News Portal is presenting a news article named "Study finds open source key to European ICT competitiveness" which underline the economic impact of Free/Libre Open Source Software (FLOSS) on the European information and communication technologies (ICT). The mentioned study report also says that increasing the use of FLOSS could provide a way for Europe to compensate for low ICT investment as a share of gross domestic product. "A growth and innovation simulation model shows that increasing the FLOSS share of software investment from 20% to 40% would lead to a 0.1% increase in annual EU GDP growth excluding benefits within the ICT industry itself - over €10 billion annually," it states.

Linux Standard Base plans cross-format package API

For independent software vendors (ISV), one of the major problems in supporting GNU/Linux is the variety of package management systems. However, if the Free Standards Group has its way, the next version of the Linux Standard Base (LSB) will solve that problem by providing an application programming interface (API) that acts as a bridge between the major package systems and software installers. Ian Murdock, CTO of the Free Standards Group, says the solution could be included in the most widely used distributions by early 2008.

Hot skills: From hobby to ubiquity, Linux continues to expand

About 25% of enterprises will be running mission-critical business applications on the Linux open source operating system by 2009, according to a survey by Saugatuck Technology and BusinessWeek Research Services. By the end of 2007...the figure will be 18%. But this follows the revelation by IDC that after four years of double-digit growth, sales of Linux servers are slowing down. Although Linux servers now represent 11.8% of all server revenue, growth for the third quarter of 2006 was about 16% of that for the third quarter of 2005. Hewlett-Packard sells the most Linux servers, but it is less actively committed to Linux than IBM and, latterly, Sun.

Consumer Electronics: Closing In on Open Source
