I was originally going to go with, "Real-time. Java. Are we talking the same real-time?"
"Hardware paused for GC", doesn't strike me as 'real-time', or at least as I understand it.

It does depend, of course, on how complex a "thing" your T in IOT is, but I tend to think of really simple things.
(In some use cases, I'm going to flush them down the drains or glue them to trees...)
These things could probably be programmed using a single-threaded, integer only, no recursion, functional language. Ideally something provable...

It's very irritating to watch a group try to redefine a term, especially related to technology:
"Oracle has promoted Java SE for real-time systems, suggesting that Java SE has been enhanced sufficiently to meet soft real-time requirements."
"Soft here has at least two distinct related meanings. One is that requirements have to do with average behavior;"
"...it's good enough that an average bank transaction will post within 300 milliseconds."
"This is in contrast to hard real-time requirements, such as the requirement that a particular locomotive-switching solenoid close at worst within one-and-a-quarter seconds of the application receiving a specific alarm."
300 milliseconds and 1.5 seconds are reasonable for desktop, web and mobile apps.
The deterministic requirements for the real-time systems that I have worked on were in the realm of micro-seconds to 100 ns.
Maybe their interpretation of real-time is that it happens so fast you don't need to display the spinning hourglass icon...

So the implication being that worst-case Java execution could take more than one-and-a-quarter seconds to call a function with a boolean parameter? I believe it.

WinBeta has learned that Microsoft is planning to launch a successor to the Surface 2 soon, however it won’t be a Windows RT based device. Retired Technology

Microsoft said Wednesday that it plans to make the core viewing and editing features of Office free for devices with screens of 10.1-inches or smaller. I predict a number of companies will be upgrading to small screen machines soon

Servers and VDIs? With no screens?
|
|

I think that counts as <10 inches! Start installing!

Microsoft is hosting a small conference this week to help key partners and developers get up to speed on Spartan and how to best work with the new browser. Fingers crossed for Marquee to make its comeback!

I just found out yesterday (maintenance on some -very- old code) that Firefox still recognizes and properly displays marquee tags.

I'm not sure what's more frightening - that it does actually still work, or that you had code that tested that.

That test seems dubious to me. That sounds more like string concat vs non-string concat rather than in-memory vs disk write. The "disk" version of the code likely wasn't concatenating strings, so there was no GC activity. I wonder if they had tried StringBuilder (or whatever its Java counterpart is) if the results wold have been different?

Thanks, I'd forgotten good jokes could be found outside The Lounge.
"When I was 5 years old, my mother always told me that happiness was the key to life. When I went to school, they asked me what I wanted to be when I grew up. I wrote down 'happy'. They told me I didn't understand the assignment, and I told them they didn't understand life." - John Lennon

So, essentially what they're saying is that if you want to write something to disc, it's quicker to write it to disc with a little bit of processing than with more processing.
Y'know, if I were working on architecture at that level, I have a funny feeling I'd have maybe figured that out for myself.

I think you posted your flame to the wrong place. Otherwise
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?
