Of course :-)

more webapp-focussed - http://blog.moonfruit.com/post/2012/08/08/Perl-Application-Developer

or more systems focussed (scaling, soa etc ) - http://blog.moonfruit.com/post/2012/08/08/Perl-Platform-Developer

Bizarrely no-one put contact details on those blog posts, but email jobs@moonfruit.com if you are interested. 61 would not be our oldest programmer :-)

You're not too old for a permanent job at 61! Srsly, how many permanent staff stay more than 3-6 years anyway?

{spam}btw we are hiring perl programmers in london (w12/oxford circus) and tbh I'd love to hire someone who is keeping up and interested in new things - nosql, scalability, soa etc{/spam} - seems like lovefilm slurped up every perl programmer left in london :-)

Sorry, I meant that continuing to support XP means writing updates to fix newly-found security holes. If they don't, they'll look bad when the inevitable rampant virus emerges and takes over 43% of the world.

IMO the cool thing about the raspi is that you can just give one each to your kids. The laptop is still sufficiently expensive to be shared, and fixing it so the others can get to wikipedia for homework research is sufficiently annoying and time consuming to discourage too much messing about.

I gave my 6-year-old his own account on my macbook; within a week he had magically managed to change some font anti-aliasing option that affected all users. Took me hours to fix, he now has a completely locked-down account. I can give him a raspi of his own and if it breaks everyone can still use the family computer while he uses his sister's raspi to automatically reimage the OS on his SD card.

Given that they have been required to produce 'posters' since primary school and the first thing they want to do is change the font to comic sans, *yes*, they all know how to open a document and change a font.

At least since year 2 (6 year olds), anyway. TFA is about secondary ICT, which is incredibly *still* about powerpoint/word up to GCSE level.

When I asked one teacher if they taught any programming in ICT responded 'There's no point, because any language we teach them will be obsolete by the time they leave' (he didn't see the irony that he was teaching kids to use office 2003 in 2011). Would love to see the look on his face today :-)

The source says 'children as young as four' have mobiles, meaning that 55% of all 4-9 year olds must have a mobile in order for the "33% of under tens" to be true

One-third of 8-10 year olds I can believe (most people I know are getting their kids phones when they start secondary school at 10-11), but 55% of 4-9 less so.

"The consoles are close enough in raw power that the talents of the developer and style of the artists is far more important than the console."

There is a nice gap, there, in raw power.

There's a nice gap there in *theoretical* raw power. As the OP pointed out, in reality there's pretty much nothing in it. And the point is moot, as the wii is running them both ragged in terms of sales.

Google

+ - Google takes aim at MS with ChromeOS

Submitted by HSRD
HSRD (1013325) writes "Google is preparing to launch an operating system for personal computers next year, taking direct aim at the dominance of Microsoft Corp's Windows franchise. The system, based on Google's Chrome web browser, is designed for all classes of PCs, "from small netbooks to full-sized desktop systems", and will be available in machines from "multiple" PC makers in the second half of next year, the company said."

E. J. Maffei (1026354) writes "From the New York Times (Click here for full story):

In a direct challenge to Microsoft, Google announced late Tuesday that it is developing an operating system for PCs based on its Chrome Web browser. The move sharpens the already intense competition between Google and Microsoft, whose Windows operating system controls the basic functions of the vast majority of personal computers. In a post on its company blog, Google said the operating system would initially be aimed at netbooks, the compact, low-cost computers that have turned the PC world on its head. It said the open-source software, called Chrome OS, would be available in the second half of next year.

Fascinating that Google — a company that went berserk over Microsoft bundling a browser with an OS — now thinks it's OK to bundle an OS with a browser."
Data Storage

+ - Solid State Drives tested with TRIM support->

Submitted by Vigile
Vigile (99919) writes "Despite the rising excitement over SSDs, some of it has been tempered by performance degradation issues. The promised land is supposed to be the mighty TRIM command — a way for the OS to indicate to the SSD a range of blocks that are no longer needed because of deleted files. Apparently Windows 7 will implement TRIM of some kind but for now you can use a proprietary TRIM tool on a few select SSDs using Indilinx controllers. A new article at PC Perspective evaluates performance on a pair of Indilinx drives as well as the TRIM utility and its efficacy."

Programming

+ - Can 15 devs handle 3 million lines?

Submitted by
An anonymous reader writes "We have a legacy product containing about 3,000,000 lines of code. The code is C and C++, but about half of the code uses techniques borrowed from Fortran. For example, there is extensive use of global data and many parts of the code use fixed sized arrays. Some work is being done to restructure the code and remove these problems.
The product is financially successful and brings in tens of millions per year. Yet we have decreased the size of the development staff. Ten years ago we had about 40 developers, but we are down to 15 now. There is a backlog of 600 bugs and 200 proposed projects. It looks to me like we barely have enough staff to cover the high priority bugs without touching any new project work.
What's a reasonable development staff for a product of this size? Should we try to work on new projects? Or should we just mothball it since there are not enough developers?"

Seriously, this sounds like Good News for the industry. An API for set top boxes that is more open than OpenTV, and has a sensible desktop client which can preview what it will look like on deployed machines?

Flash can scale for 4:3 and 16:9 machines instead of having a single bitmap font (cf: opentv, mheg, liberate). It antialiases fonts properly (cf: liberate, or 'at all' wrt opentv/mheg). It renders predictably (cf: ce-html). It allows you to use your own display fonts (cf: liberate, mheg), and predict how much content will display per page programatically (scrolling bad, paging good).

It allows for compression of content using zlib, for vector, resolution-independent graphics (smaller than the equivalent, SD-res jpeg).

I'm just hoping it gets deployed widely and that they find a sensible way to have a hardware player.

Which is why fusion-io is different from normal SSDs. The devices have 20% or more spare capacity and use a log-based FS with block mapping, so your writes don't go through the read/erase/rewrite cycle.

Obviously there is a little slowdown once the 20% has been used up and it goes into garbace-collection mode, but there are plenty of white papers around about steady-state usage (ie once it has started GC) and you can opt to use even less of the physical capacity in order to get more performance. See http://www.oracle.com/technology/deploy/performance/pdf/OracleFlash15.pdf for example.
