you could do this to avoid the wrong class thing
code:
Logger logger = Logger.getLogger(this.getClass().getName());

can't use it in static methods & slow as balls depending on impl

also deceptive as hell if you use concrete inheritance, not that that is usually a great idea anyway

Jerry Bindle: May 16, 2003

idk if any mcu's use java, but a debug build will have additional stuff in it like symbol information which is taken from the source code. in the case of PICs there is also an additional debug executive which takes up more space. although the debug executive is placed in test memory so thats not a big deal i guess.

python-pcyopg2 wants me to put a plaintext password in my python script to connect to a database

whats the best way to not do that

This is from way back but I've done something like this in the past:

Python code:

def get_env_setting(setting):
    """ Get the environment setting or return exception"""
    try:
        return os.environ[setting]
    except KeyError:
        error_msg = "Set the %s env variable" % setting
        raise Exception(error_msg)

# then later...
DB_PASSWORD = get_env_setting('DB_PASSWORD')

This way you don't ever check passwords into CM. If an attacker can read your environment anyway then you've already lost. Bonus points for subclassing Exception into a more useful error.

the old argument for java on microcontrollers was that bytecode is a lot more compact than most "natural" assemblers for higher-level tasks. don't know if any of that movement survives though, would like to think that forth has a foothold in that niche still

Yeah, this is the way I do it. Any instance specific settings go into a config.env file, that I can even isolate to just the run with:

code:


#!/bin/bash

export $(cat config.env)
exec ./run_my_dumb_application

I dunno if there's a better way to do go about it, but hey, every programming lang has ways to get environment variables so no matter how a web framework or library implements their config, there's probably a way for me to get those environment variables in there.

The config.env is just a simple line of environment variables:

code:


FOO=thing
BAR=anotherthing

like the JavaStations that were a microSPARC

Jesus gently caress just give me a microSPARC (with SunOS 4.1.3 please) and leave this Java poo poo at the doorstep

only plus about the JVM is server-side ubiquity, .war deployment is the only reason WebObjects 5 was a good idea

Necc0: Jun 30, 2005; by exmarx; Broken Cake

this is fun: in my system we have transactions that can have line items that are listed off in sequence ie: 1, 2, 3, etc. apparently there's no central component that handles this and in all the hundreds of different ways transactions can turn into other types of a transaction they're all generated on their own in their own unique snowflake way. turns out some programmer decided he didn't want to go through the effort of numbering these line items and instead used our global sequencing class meant for the database to number them so instead of 1, 2, 3 it's 23009876, 23009888, 23009912, etc. because at least those are guaranteed to be unique, right?

this is like the most trivial complaint about a language that is filled with idiocies

there are plenty of languages that are the same (c, java, everything descended from the two). the only languages i can think of that have exponentiation operators are either plangs or greybeard poo poo like ada and fortran

int fit in doubles and long long fits in long double anyway

yeah i dont really care and wouldn't have noticed except i was using it for project euler

it's just funny since it's a language that literally bills itself as 'a plang but with static typing and maybe a little bit fast'

the standard library is just very anemic for something that's supposed to be a sane alternative to ruby and python.

the syntax is nice and goroutines are cool and i like interfaces and getting out of class hell. but if they want to be popular with ruby people it should provide more hand holding

I mean, it's maybe somewhere in between? It's certainly not nearly as painful as C or C++. At least in terms of syntax. I haven't used it enough to be aware of any hidden horrors.
