this is a cool slide deck about what they want to do with the jvm now

tl;dr: what they want to do is have value types and something equivalent to reified generics by, uh, 2030.

i am pretty sure this is why eclipse has a splash screen

eclipse is made up of a billion plugins and that load screen is where it reads and loads each one. uis are created on demand which is why the first time you open certain dialogs it will be slow while it loads the classes but then be fast afterwards

swing is ok, swing performance is fine as long as it's done properly with worker threads and stuff. slower than native guis, faster than 100% of web apps i've ever had the misfortune of using.

the swing api is pretty lovely though, i'm not gonna defend that.

the two major gui apis for java (swing and eclipse swt) haven't changed since java 1.4.

eclipse rcp looks kind of nice until you realize you have to use swt and then it really sucks

Hey, they added generics to things like JList.

So now you can pass a Vector<? extends E> to the JList constructor. :downs:

the version numbers go like this:

java 1.1
java 2 se 1.2
java 2 se 1.3
java 2 se 1.4
java 5
java 6
java 7
java 8

this is from the same vendor who gave us this version series for their operating system:
4.0
1.1 (4.1)
2.0 (5.0)
2.2 (5.2)
2.3 (5.3)
2.5.1 (???)
2.6 (5.6)
7 (5.7)
8 (5.8)
10 (5.10)
11 (yep, 5.11)

i think i found a compiler bug in avr-gcc or at least if not a bug then weird/unexpected behavior

# ? Feb 5, 2015 21:17

Bloody: Mar 3, 2013

the crux of it is the following pseudocode:

code:

char flag = 0
ISR(interrupt trigger)
    flag = 1

main()
    while(1)
        if(flag == 1)
            do a thing
            flag = 0
       else do nothing

i would expect flag to get set in the isr then, at some point, checked in the main loop and the conditional code there executed

it does not do this

# ? Feb 5, 2015 21:20

Subjunctive: Sep 12, 2006; ✨sparkle and shine✨

did you mark flag as volatile?

maybe it thinks flag is a string instead of an integer?

volatile makes it work yeah but i dunno i feel like it shouldn't be necessary in this case

this is like the classic example of when to use volatile: there's a mutation that's not visible to the control flow. otherwise it could never hoist any loads, it'd have to rematerialize every time through the loop, you would cry yourself to sleep, etc.

tbh compilers targeting avr or msp or whatever should probably consider everything volatile and also aliased by everything else by default but yeah it's free to hoist poo poo out of loops unless you tell it not to (and even if you mark things as volatile, the spec allows a compiler to eliminates stores to a var where it can't find any loads but i don't think any compiler is petulant enough to actually do that)

yeah, the trick is to get it so that when the result of following your advice is a disaster, people think the problem is that they didn't listen to you enough

it works great for economists too

an excellent point

have you tried holding down + B when you trigger the interrupt, OP

you have to press it on the third iteration or it doesn't always work
