A turbine isn't the best motor for a vehicle. They use about twice the fuel for the same amount of work output. Their main advantages are that they produce a lot of power with small size and low weight. This means that for an aircraft, they're more efficient above a certain power output because the fuel you save from reducing weight and drag more than offsets the increased fuel consumption.

Gas turbines were used in railway locos occasionally. Their main advantage there was that they could burn heavy fuel oil rather than diesel, which was less than half the price at the time. When the price of heavy fuel oil increased, they became more expensive to operate, so Union Pacific scrapped them all. Some German passenger locos had turboshaft "booster" engines added to increase power to allow faster running on high-speed route sections. However, the frequent starting and stopping led to premature turbine failures. "Turboliner" type multiple unit trains used gas turbine engines, but as piston engines have improved, diesel-hydraulic drive trains have displaced them.

If you look at warships, they'll often have piston engines as well as gas turbines (CODOG - combined diesel or gas turbine). They only use the gas turbines for occasional high-speed running because the diesel piston engines are a lot more efficient.

Gas turbines in cars just don't make sense.

Comment Keynote vs PowerPoint (Score 1) 31

I've always struggled with PowerPoint but was able to quickly put together decent looking presentation with Keynote.

I haven't used Keynote in years, so things may have changed, but back when I did use it, I found it was a lot quicker for doing simpler things, but fell over when you needed to do more complex stuff. PowerPoint had a far steeper learning curve and required you to do a bunch more work to get your templates set up, etc. or you'd end up with a mess that was difficult to edit. But it had more flexibility and you could do more with it if you needed to.

LibreOffice seems to be the worst of both worlds. All the complexity of PowerPoint, more pitfalls, templates break in unintuitive ways, and it falls over on complex stuff anyway.

Comment Remember OLE? (Score 1) 31

OLE allowed applications to register servers that allowed embedding interactive objects like that. It worked pretty well back in the Windows 3.1 days. I remember embedding ABC Flowcharter diagrams in my Word documents, etc. Now it seems to only be used within the Office suite. LibreOffice has an OLE clone of its own, but it only seems to work within the suite as well.

Apple tried to copy OLE a couple of times, first with the publish/subscribe mechanism (which wasn't very good), and then teaming up with IBM and others for OpenDoc, which never gained market traction.

But the demise of OLE and that integration between applications from different vendors really feels like a step backwards.

What will most likely happen is that cable companies, fiber last mile providers, etc. will become telecommunications companies, handling the connection between customers and various Internet services.

Australia requires unbundling like this. The major last mile networks serving residential properties are the government-established NBNco, TPG's WonderCom and Lightning Broadband. NBNco serves the most properties and has the widest choice of ISPs available. WonderCom cherry-picks the properties they want to serve (mostly apartment buildings) and last time I checked you could only get TPG service over WonderCom. Lightning Broadband serves relatively few properties in limited geographical areas. You get a choice of a few ISPs on Lightning (including Lightning themselves), and the network is pretty good - less congested than NBN.

There's some loophole that allowed property developers to make a deal with an "embedded network" when building an apartment complex that means you don't get a choice of ISPs. I haven't experienced this. I've got Lightning fibre in one apartment and NBNco DOCSIS cable in the other.

Comment innovation is - sadly - dead at Apple (Score 1) 81

the company has, in the pursuit of easy profits, constrained the space in which it innovates.

Quite so. It's been how many years since something really new came out of Cupertino? Granted, Apple is more profitable than ever, but the company clearly shows what the result of placing a supply-chain expert as the CEO does.

The really sad part is that there's nobody ELSE, either. Microsoft hasn't invented anything ever, Facebook and Google are busy selling our personal data to advertisers, and who else is there who can risk a billion on an innovation that may or may not work out?

The successor to System/360 is IBM Z. Db2 for z/OS is still available and supported, though, so jfdavis668 is wrong anyway. AFAIK there are currently two different products called Db2 - the one for Linux, AIX and Windows (current version is called 12.1), and the one for z/OS (current version is called 13.1).

IBM i doesn't actually use Db2. There's an integrated RDBMS in the SLIC virtual machine, but it isn't treated as part of the Db2 product family.

My "cheap" Galaxy S23FE has a 120Hz display standard, and it's almost two years old now. I turn it down to 60Hz to save battery. So Apple has added a useless feature that just drains battery faster to their base model over a year after competitors had it on their budget models anyway.

Apple fans already have a heartrate sensor on their wrist, they don't need one from the ear.

That's wrong. I stopped using wrist watches 25 years ago and haven't looked back a single day. I don't want shit on my wrist. Try living without for a year and you'll realize why. It's hard to express in words. It's like having a chain removed.

Headphones, on the other hand, I use occasionally. For phone calls or for music on the train, plane, etc. - and especially for the plane if the noise cancellation comes close to my current over-the-ear Bose I'd take them on the two-day business trips where I travel with hand luggage only and space is a premium.

Do I want a heartbeat sensor? No idea. I don't care. But if there's any use for it than at least for me that's not a replication. I'm pretty sure many, many Apple users don't have a smart watch.
