Is RSA encryption broken?

First spotted on the ILUG mailing list, it appears that a young 16 year old student has cracked the RSA encryption system and won 1st prize at the BT Young Scientist Competition 2007.

If it’s true then Internet commerce could be in for a rough time, but some previous winners have proven to be less than remarkable when seen against the cold light of day. This comment from the winner, Abdusalam Abubakar, seems to indicate that the method used might not be that effective either. Check out this ILUG thread for further discussion. Can it be true he wrote it in Visual Basic?

“It was great, unbelievable. I didn’t think I was going to win anything. I didn’t want to be optimistic,” he told The Irish Times last night. Abdusalam, whose name translates into “man of peace”, based his initial work on partially successful attacks on the world’s most widely-used encryption system, RSA, mounted by two mathematicians. He decided to take the best aspects of both and generalise a new approach, which he believes has the potential to tackle at least some less complex coding systems.

Idiots on the road on film

Gardai are investigating a video found on bebo.com made by two lads from Cork. They made a video of themselves driving at 200km/h through the Jack Lynch Tunnel and then posted it on the Internet for all to see. I wonder who did they think would watch the video? Has the video made it outside Bebo yet? Apparently the Gardai have asked Bebo.com to take the video down so it could be gone for good. Pity, it could go down in Irish Internet Folklore.

While we’re waiting, here are two lads who decided to drive at speed through Dublin city center, at least until they passed an unmarked Garda car. (via Blogorrah)

The video might not be playing, but you can view it here still. Not sure why but it’ll probably right itself eventually. Note the comment from the driver:

They stopped us because it was an english reg in dub& they thought the car was stolen by a couple of nackers, also you cant see clearly but it was v. bad driving in rain,nearly ran someone down,run red light,speeding in bus lane,a guy videoing it in the front seat which they saw.
Normal cops dont threaten to shoot you and if it was normal cops we’d ave been in the shit. He started to search and got a call.

And this comment was definitely not made by an Irish person, like,

Why is everyone using like at the end of every sentence what ever the fuck that means?!!!

Ask the developer

On January 20th I’ll be speaking at BarCamp South East on the subject of WordPress.com and WordPress MU. The talk is titled, “WordPress.com – running the biggest wpmu site in the world” which is vague enough that I could talk about anything but I’d like to know what you want to hear.

Public speaking isn’t my strong point, I prefer to be behind the keyboard, or looking through a camera lens but sometimes you have to push yourself to do unfamiliar things. Here’s my go at public speaking.

Talks will be in 45 minute slots and I would like to make mine more of a discussion forum like the WPMU talk we had at WordCamp way back in August last year. It went really well and everyone got something out of it.

Subjects I’m considering include:

  • Merging code from WP core which is horribly exciting, have you ever seen vimdiff in action?
  • Site stats – did you know we publish them?
  • Hardware – server porn. How do we handle the load generated by Slashdots, Diggs, and almost 600,000 blogs?
  • Hooks and plugins – new hooks in the signup process and wpmu admin backend.
  • Anyone interested in working from home and virtual company issues? Automattic has employees in at least four countries.

So, if you’ll be there I want to hear from you. If you won’t, I still want to hear from you because I’m sure Bernie or someone will record the talk and put it up online.

Airtricity – switch now?

Airtricity are running an advertising campaign on the radio currently in an effort to get businesses to switch to them from the semi-state monopoly electricity generator, ESB. They offer to save you 10% off ESB prices and they’ll freeze your energy prices until 2010. That’s very attractive considering that the ESB is getting yet another price increase this month from the rubber stamping regulator. Unfortunately when you click “Switch now” on their site all you get is an error message:

XSLTransform Error

XSLTransform: Unmatched end tag.

Oops. That’s a pity because I wonder if I qualify as a small business being a self-employed person working at home. I’ll have to check back later.

Body of Joseph Mullally found

Twenty year old Joseph Mullally went missing last December 14th after he was last seen outside The Brog on Oliver Plunkett Street. An extensive search for the last several weeks went on involving volunteers and emergency personnel turned up nothing until this morning at 10am when 4 of the searchers found his body at the quayside in Tivoli, downstream of the city.

Irish traffic to drive on right

The Irish Government will start the process of converting our traffic system to a right hand drive one in the next few months. The current system of driving on the left is a legacy of British rule in this country but now that we’re part of the EU this change is finally taking place. Grandad has more details on his blog.

I expect this will be a welcome change for tourists and foreign travelers to our shores, especially Polish people who will no doubt start businesses teaching people to drive on the wrong other side of the road.

Initially, all buses and articulated vehicles will move to the right to allow for a period of adjustment. Car owners may opt to make the switch themselves on an individual basis, depending on their level of confidence.

Starting on the 1st of August, all motorists outside city limits will be required to drive on the right. And finally on the 1st September, all city traffic will make the transition.

Irish Blog Awards on March 3rd

The second Irish Blog Awards will take place on the 3rd of March in Dublin. Damien wants to know if you’re going so leave a comment on his post if you’re interested. I have yet to make up my mind but there’s already a number of comments left and it will probably be even bigger than last year!

If your company is looking for exposure in the blogging community, there are a number of sponsorship slots still left to fill. More details on the page linked above.

Choosing a memory foam mattress

Yawn. The mundane things in life are top of my agenda today. We’re looking for a new mattress and considering how much time is spent asleep in bed it’s criminal not to buy the best you can afford.

From research it appears that memory foam mattresses are the best to go for. I would certainly hope a new mattress would help my sore back! Tempura mattresses have been recommended to us but they’re hard to buy in Cork. Casey’s Furniture have them but they’ve always been over priced in their city center location. Another brand I have come across is Visco and it appears to do the same job. According to one salesperson they’re firmer than Tempura mattresses but I need to ring around a few more places before we make up our minds.

If you have one of these mattresses I’d love to hear about how comfortable they are. Try searching for any information on either brand and you’ll only find are online-stores trying to flog you one!

This page is better than most however. Here’s what they say about Visco-elastic mattress, which I presume applies to Tempura too.

  • Body heat reacts with the foam to soften it.
  • The mattress then moulds and re-moulds to your body’s contours.
  • Provides excellent support and enables natural movement during sleep.
  • Helps to maintain correct posture and align spine horizontally when lying on your side.
  • Hypo-allergenic with anti-microbial properties.

Off to town shortly and out with the credit card..

January 3rd 2007 – we went into town this afternoon and tried a few places before buying a bed in Swan Beds. It’s a memory foam mattress. A bit pricey but less than Casey’s were looking for. Hopefully it’ll be delivered next Wednesday!

Is the Sony Ericsson K750i a good upgrade?

I’ve had a Nokia 6320 or something like that for well over a year so I think it’s about time I treat myself to a mobile phone upgrade on my Meteor account. My brother bought a Sony Ericsson K750i, I had a brief play with it and I’m impressed. This review from last year paints a rosy picture also but it’s only one of a number of phones available from Meteor.

What do I need my mobile phone to do besides the basic calling functions?

  • A half-decent camera would be nice. I don’t want a 1.3MP sensor! The K750i has a 2MP sensor. That will do nicely.
  • I’d prefer a radio to an mp3 player but having both would be a bonus.
  • A messaging system that deletes all reports with one push of a button is very desirable. Some of the Nokias make you delete the delivery reports one by one!
  • I don’t like clam shell phones, but I could be swayed.
  • I don’t care about owning the newest and greatest phone on the market and I’m price conscious. As my bills are low each month I want to go for the cheapest call package which Meteor offer. That would be Meteor 60 I think.

Decisions, decisions. I probably won’t get a chance to go into a Meteor store today but maybe sometime over the next few weeks.

Update! I bought the Sony Ericsson W810i. Here’s my mini review and initial impressions. There’s not much between it and the K750i that I can see except:

  • It comes with speakers which could be useful for the radio/mp3 player but probably not.
  • It has a 512MB memory stick duo card.
  • Battery life is reduced.
  • The styling is a little different. The camera doesn’t have a slide-open cover.

Initial impressions are good except:

  • When texting, the predictive text engine, T9, pops up a small window with a choice of words or symbols by default. I turned that off. Choosing a new word requires the use of the small joystick instead of the * key. Something I’ll get used to, but so far it means I need to type 2-handed.
  • Delivery reports are switched off too, but that’s been the case with every phone I’ve owned. As Donal said in the comments, the report doesn’t go into my inbox! Woo!
  • The SPACE character shares the # key instead of the 0 key. It’s a minor niggle but I find the space in the middle of the keyboard is easier to tap with my large hands.
  • The SIM card is a pain to get out requiring 2 fingers to push and pull it out.

Those are mostly minor problems, and some are from familiarity with Nokia phones. My first phone was a Panasonic and it had the space character on the # key too so I know it’ll become second nature to me eventually. I like the camera. It’s a 2MP sensor, adjustable exposure value, white balance and even has an illuminating light. Movies are stored in 3gp format but I’m sure there are ways of converting them to an online-friendly format if I look. The Walkman app looks promising and I’ll play wih it a little more once I’ve added a few mp3s to the memory stick.

The W810i has a handy panorama feature where the phone will stitch together 3 photos to make one larger image. It displays a semi-transparent portion of the previous image on the left of the screen for overlap purposes to allow you to line up the next shot. It works quite well too. Here’s a shot from O’Brien’s Sandwich Bar in Blackpool shopping center this morning.
