I'm surprised no body's mentioned the Leaf as a currency.

Tech Companies Set To Appeal 2012 Oracle Vs. Google Ruling

EricTheRed Re:When you count from 1 to 10, do you stop at 9? (198 comments)

This is crap. Either 'toIndex' actually means 'onePastToIndex', or the final if test should be if (toIndex >= arrayLen) .
Try calling this function with arrayLen=10, fromIndex=1, toIndex=10 -- no exception, despite the zero-based array's last element being index 9.
If you ask somebody to count from 1 to 10, do they stop at 9?
If you see the following prototype: int randomValue( int fromValue, int toValue), what is the highest value you would expect could be returned?

Identifiers should be named accurately! Bad identifiers like this make code unnecessarily difficult to read, and makes it easier for bugs to go unnoticed.

If the allegation is that Google copied this code, and they've replicated the bad names along with the trivial algorithm, it does seem likely they authored their version via cut & paste...

It might actually be correct, it depends on what's calling this method.

For example take either String.substring(begin,end) or String.subSequence(begin,end)

In either of those methods begin is the first inclusive index but end is the last exclusive one , so when you want chars 1..9 then begin is 1 but end is 10

There's plenty of api call's in there which follow the same pattern.

Ubuntu Touch On a Nexus 7: "Almost Awesome"

EricTheRed Re:No Generic OS for Mobile devices yet. (116 comments)

Cyanogenmod is doing a good job getting a more unified version of Android on many vendor's devices. I have several devices using it and it works well. (http://www.cyanogenmod.org/)

I have to agree. Currently running it on a Nexus 4 & 1st gen 7 as well as a 1st gen Kindle with no problems whatsoever.

11-Year-Old Coloradan Will Brew Beer In Space, By Proxy

EricTheRed Re:Very safe indeed (129 comments)

Not all beer is carbonated with CO2. In fact most of the beer I drink isn't carbonated at all... i.e. true Bitter :-)

The "healthier than water" part comes from hundreds of years ago when Beer was cleaner than water.

Milestone: The Millionth UK-Made Raspberry Pi

EricTheRed Weather Station, time sync (129 comments)

First one has been running for well over a year now connected to the Weather Station, uploading to various locations including twitter. The Register even picked up on this one as part of a 20 things to do with a pi.

The second is an NTP server using GPS as the time source.

The third is a pure experimental/dev PI.

I've got one more model B & two A's just waiting for a project.

Been meaning to setup a PI Cam on one to complement the weather station so that I get a sky camera (cloud cover by day, long exposure at night for meteor's etc.

Compared to my 1st computer's memory ...

EricTheRed Re:Missing alternative (587 comments)

Yes the TI-99/4A was my first computer & it did indeed have 16K of ram. It was even 16 bit which most people don't realise for a machine out in 1979/80!

A pity I didn't try it back then but there was a rudimentary genlock in the display circuitry which was why one of the system colours was called "Transparent" :-(

Ask Slashdot: Getting Hired As a Self-Taught Old Guy?

EricTheRed Re:Start your own (472 comments)

With the young ones, I think you've been lucky & I've got the rest of them :-(

As for the older ones, yes you can't get stuck with older technology. If you don't keep up it's quite easy to get left behind. Sometimes the problem is that they were held back, now that's a real problem & to me would be time to look elsewhere.

Ask Slashdot: Getting Hired As a Self-Taught Old Guy?

EricTheRed Re:Start your own (472 comments)

This isn't just in the US either, we have the same problem here in the UK.

Over the years I've seen loads of youngsters who straight out of university think they know everything until they get the sharp shock of reality.

Businesses go for them as they are cheap but it's those of us who have been around for decades that end up cleaning up the mess or attempt to train them.

There are some are so arrogant they don't want to accept they are wrong, they are the worse.

Nb: I'm self taught, didn't do university & still overworked in my mid forties!

When Was the Last Time You Used a Landline Phone?

EricTheRed Landlines are for broadband (329 comments)

I've not used an actual landline phone in years now.

At home I have a landline but there's no phone attached, just the VDSL modem for my fibre connection.

For phone calls I always use the mobile or VoIP so no landline phone there.

Even in the office it's a VoIP connection.

Ask Slashdot: What Is the Best Way To Add Forums To a Website?

EricTheRed Re:vBulletin (259 comments)

Yes they have as one of my sites using PhpBB suffered from at first.

What I do to get around the scripts is:
1: Have a captcha - although not too complicated as I've found some disabled users have problems with it
2: Restrict posts to be moderated for the first few posts made by a new user. Once they hit a certain limit then their posts go live immediately.

No 2 is important because some people from India, Korea and China are paid to post to forum sites so doing this also captures them as well.

Initially there's a burst of spammers but this falls off as they find out which sites are pro-active in killing them. I still get the odd burst of spam, usually on a Monday morning but it's manageable.

Microsoft Retiring Messenger, Replacing It With Skype

Microsoft Retiring Messenger, Replacing It With Skype

EricTheRed XMPP (213 comments)

I wish I could retire my msn account but unfortunately it's still the preferred IM system for most here in the UK.

Personally I have my own xmpp server running for IM. Not only is it open but it's also means that I'm in control of my contacts & know that, if it fails it's my own fault ;-)

If I need to talk to someone on Google Talk or other xmpp severs its no problem as its federated correctly so I'm pretty much covered.

I'm just wondering what those insisting on msn will do now or the chaos when this happens next year.

Ask Slashdot: Using a Sandbox To Deal With Spambots?

EricTheRed Re:Old Idea (167 comments)

I see the same thing in my forums. The capcha gets the spam bots but the mules (humans being paid pittance to spam) still try to get through, strangely they tend to post on a Monday morning.

What I do to catch them is:
* moderate the first X posts from any user.
* don't allow posts from certain countries, usually India, South Korea & China.

There's no automation on this as its low volume anyhow but it does work.

I most recently switched ISPs ...

EricTheRed This presumes just 1 ISP (250 comments)

I currently have 2 isp's one for home & one mobile one for when stuck on the train. The latter I change a couple of months ago but the home one I've been using for almost 4 years now.

As there's fttc cabinets out I the street now I'm now waiting for those to come online & then switch that one.

EricTheRed Just the one but two if my rail photo card counts (380 comments)

yes same here. I have my passport at home & rarely use it - sometimes if I have to collect from the local sorting office (I don't have a drivers licence) or if I go abroad.

I do have a rail photo card but that's not official in any means - but is acceptable at some london data centres as ID which makes security a joke!

voyager had finally left the solar system

EricTheRed EricTheRed writes  |  about a year ago

EricTheRed (5613) writes "The BBC is covering the good news that Voyager 1 has finally & officially left the solar system.

http://www.bbc.co.uk/news/science-environment-24026153

What I like to think I'd that a computer from the mid 1979's, older than most people here on Slashdot is still running.

Not many of us have computers anywhere near that old that are still usable — OK got a BBC micro & electron that still work but even they are 5-6 years younger.

Well done to the original JPL Tech's"

Raspberry PI Model B now has 512Mb of ram

EricTheRed EricTheRed writes  |  about 2 years ago

EricTheRed writes "The raspberry pi foundation announced this morning that as of today the Model B is shipping with double the memory — 512Mb of it.

"With this in mind, we’re pleased to announce that from today all Model B Raspberry Pis will ship with 512MB of RAM as standard. If you have an outstanding order with either distributor, you will receive the upgraded device in place of the 256MB version you ordered. Units should start arriving in customers’ hands today, and we will be making a firmware upgrade available in the next couple of days to enable access to the additional memory.""

Sir Maurice Wilkes, early programming pioneer dies

EricTheRed EricTheRed writes  |  more than 3 years ago

EricTheRed (5613) writes "Sir Maurice Wilkes — one of the early programming pioneers of the 1940's has died.

The National Museum Of Computing based at Bletchley Park announced on their twitter feed earlier:
http://twitter.com/#!/tnmoc/status/9283716039843841

Sad news that today Sir Maurice Wilkes passed away, aged 97. Here he was on a visit last year to #TNMOC http://ow.ly/3gUD2

from the article covering his visit to TNMON last year:

Born in 1913, Sir Maurice has been at the forefront of many post-1945 computing developments and even today, at the age of 96, maintains a keen interest and is an avid user of email and the Internet. Sir Maurice’s contributions to computing history have included the development of EDSAC, the first practical stored program computer begun in 1946, and co-authoring the first book on computer programming in 1951. His proposals for micro-programming have been widely adopted in the industry and in 1965 he published the first paper on cache memories. A co-designer, in the late 1970s, of the Cambridge Ring, a pioneering client-server system, Sir Maurice went on to work in industry on both sides of the Atlantic and in 2002 returned to the Computer Laboratory in Cambridge where he is an emeritus professor."
