What is the main topic discussed in this episode?
Let's be honest. Most HR platforms aren't exactly a joy to use. Deal's different. It's AI native, keeps you compliant, and grows with your team, whether you're five people or 50,000. HR, IT, and payroll on one platform that just works. See for yourself at deal.com. That's D-E-E-L dot com slash big tech.
Hey there, we are Indosport with me, Joe Malloy, and we have things like this.
Generally speaking, when there's a wind in Croke Park, its general direction will be down towards the canal end. Definitely when it comes to getting that bit of extra distance to make a two-pointer more viable, that's the end that you want to shoot into.
Yeah. See, this is what happens when a World Cup ends. Talking about the wind. Literally. Talking about the wind. It's a Friday.
This is the world he wants. Yeah. Now this is much better.
This is an Irish Independent Podcast.
AI is going to change all of these weather apps. It's going to change all the weather forecasting dramatically over the next few years and in a good way. So an AI weather version of the ECMWF is using 1,000 times less power and delivering the forecast much, much, much quicker.
Wow. And that's significant because when I asked Matt Aaron about why choose two kilometer grid zone as opposed to others who have nine kilometers, they said it was actually a matter of resources. as in the amount of compute and the cost, including energy.
Yeah, so AI will allow weather models to do far more, far quicker and a lot less power.

Hello, and you're welcome to The Big Tech Show with me, Adrian Weckler. Now, what is the best weather app, and why aren't we all using it? Because as the settled warm weather now starts to wane, we're all going to be looking very soon at our phones to scrutinize whatever weather app we have. But they're not made equal. Some look fantastic and operate beautifully, really nicely designed, but are factually less accurate than others. Alan O'Reilly, creator of Carlo Weather, enormously popular service online here in Ireland today. joins me.
Alan, a brief glance at the App Store shows among the free weather apps that we download, you've got apps like Meteo Blue, MedErin, Weather and Radar, YR, AccuWeather, Windy. And an awful lot of other people just use the default weather app that comes on their phone. So in Ireland, that is two phone systems. That is iPhone and it is Samsung's two brands. And both of their apps are called weather. But when you open them, you will often see a different forecast to the one that MetErin gives. Sometimes it's only slightly different. Sometimes it's significantly different. I spoke to MetErin about this and I asked them during the week. They told me that their forecast app, that they have measured their app as being more accurate than many of the other apps because they measure every hour and they measure in two kilometer zones as opposed to every six hours and in nine kilometer zones, which some of the other services do.
Are they right? Can you talk me through that?
They're 100% correct for the next 48 hours. So their weather app, their weather website uses the Harmony model, which is the best model for Ireland. It goes out to 60 hours, but generally it's six hours old by the time you kind of get the data. So really it goes out to every 56 hours.
Why is it the best model?
So that resolution, so what they're talking about is, if you think about, I suppose, SD, HD, 4K, some of the other models run at SD, some run at HD.
Standard definition.
High definition. And this basically is the size of the squares over a map of art, if you think about that. what they're saying is theirs goes down to two kilometers. So every square is two kilometers. It means that within two kilometers, they're differentiating rainfall, temperature, et cetera. So you can really drill into... So if you're planning something for tomorrow in Ireland, you can go in, you can look at their app,
