[18:36] <mr_pacific> java can be quite polarizing |

The other day I was listening to http://www.javaoffheap.com/2017/11/episode-28-back-from-javaone-with.html and they were saying that Java 9 is not a long term release. |
| 17:48 |
|
aditsu |
what does that mean? |
| 17:58 |
|
pdurbin |
It says "9 (non-LTS)" at http://www.oracle.com/technetwork/java/eol-135779.html |
| 17:59 |
|
pdurbin |
"For releases after Java SE 8, Oracle Java SE product releases not designated as LTS releases will only be maintained until the subsequent release." |
| 18:00 |
|
aditsu |
wth is java 18?! |
| 18:00 |
|
aditsu |
oh, year-based |
| 18:01 |
|
pdurbin |
heh, it's going to take some getting used to |
| 18:01 |
|
xCA7BABE5 |
are they changing versioning again? :P |
| 18:01 |
|
aditsu |
that's just begging for Y2100 problem |
| 18:01 |
|
aditsu |
or Y3K |
| 18:01 |
|
pdurbin |
It's going to be more like Ubuntu releases in terms of names based on years and LTS vs non-LTS. |
| 18:01 |
|
xCA7BABE5 |
Futurama |
| 18:03 |
|
aditsu |
so.. java 9 is out already? |
| 18:07 |
|
aditsu |
btw, I use a yyyy.mm.dd versioning system for a bunch of small libraries |
| 18:08 |
|
pdurbin |
Yeah, they talked about it at JavaOne. |
| 18:09 |
|
aditsu |
if it's not in portage, it doesn't really exist for me :p |
| 18:10 |
|
pdurbin |
I wonder how the various Linux distros will treat Java 9, since it's a non-LTS release. |
| 18:16 |
|
mr_lou |
I would prefer to never have it, so.... |
| 18:17 |
|
aditsu |
I haven't fully switched to java 8 yet, so I'm not really concerned |
| 18:17 |
|
mr_lou |
:-) |
| 18:21 |
|
aditsu |
much of my code is still java 6-compatible |
| 18:25 |
|
pdurbin |
We took a swing at upgrading our app to Java 9 but now that I know it's a non-LTS release, I'll probably be recommending that we wait until the next LTS release is out (fall 2018, looks like, according to that link above). |
| 18:34 |
|
aditsu |
you should take a javafx instead ^___^ |

wonders how big the overhead of SoftFP vs HardFP is on the ARM |
| 20:26 |
|
xCA7BABE5 |
it boils down to the following |
| 20:27 |
|
xCA7BABE5 |
HardFP is floating point operations done in hardware, as taken for granted on the x86 |
| 20:28 |
|
xCA7BABE5 |
SoftFP is floating point operations turned into a system lib call |
| 20:28 |
|
xCA7BABE5 |
up to the lib/OS to implement the said calls |
| 20:29 |
|
xCA7BABE5 |
that could be in software(soft emu of floatingpoint operations, slow) |
| 20:29 |
|
xCA7BABE5 |
or in hardware(with the overhead being the function call) |
| 20:30 |
|
xCA7BABE5 |
attempting to use HardFP libs in SoftFP environment and viceversa is a no-no |
| 20:30 |
|
xCA7BABE5 |
because calling conventions and shiet |
| 20:31 |
|
xCA7BABE5 |
I ask because |
| 20:31 |
|
xCA7BABE5 |
J2SE Embedded 7 is offered in 2x2 flavours |
| 20:32 |
|
xCA7BABE5 |
Headful and Headless, SoftFP and HardFP |
| 20:33 |
|
xCA7BABE5 |
J2SE Embedded 8 is offered only as Headful HardFP, Headless SoftFP/HardFP |
| 20:33 |
|
xCA7BABE5 |
Headful means you can run GUI |
| 20:33 |
|
xCA7BABE5 |
Headless means you can only run CLI apps |
| 20:43 |
|
xCA7BABE5 |
I expect the overhead of function call to be significant |
| 20:44 |
|
xCA7BABE5 |
based on experience with Gervil on Embedded :p |

aditsu: maybe I should try javafx some day |
| 20:50 |
|
pdurbin |
I'm not very good at building GUIs. I'd like to try some different frameworks. |
