iirc the idea behind postscript was that the same source information could be used to generate graphics to display to the computer screen and print out, and postscript was one of the earliest things of its type right?

a terrible programmer story: i spent half a day adding 10mins of features to a lovely console app because i realised that the layout was total garbage despite it only having been written 2 months before so spent ages refactoring almost every method for clarity and getting rid of stupid poo poo like nested classes with separate yet dependent bools. i was the one that wrote it all originally. I'm the terrible programmer.

dvorak is not actually faster than qwerty. what makes it seem faster is that learning any new keyboard layout is faster than your bad habits on qwerty. touch-typing is loving miraculous, and it's very, very hard to unlearn bad habits if you are a lovely hunt-and-pecker at 40 wpm you could probably double your speed learning a random layout. or colemak, for that matter. learning literally anything but qwerty gives you an opportunity to un-gently caress your typing not that i would endorse colemak or whatever flavor of the week

I I have a log4j question. Im worried about performance and was going to start creating queues that contain Strings, and then have a thread running that pollls the queue and calls Logger.debug() on anything in the queue. I have a feeling that Logger.debug () does all this in the background anyway. Is that right? The genesis of this is worrying about the logging creating overhead and blocking things that are time critical

I wouldn't worry about it until its an actual problem, but if you really want to do something there are a few things. 1) use the formatter based logging methods ex: log.debug("The boner size is {}",bonerSize); instead of log.debug("The boner size is "+bonerSize); The first statement incurs no string concatenation cost when debugging is disabled, while the second one will always concatenate the strings even if debugging is disabled. 2) when you cant do the above, wrap stuff in a logger.IsDebugEnabled statement. or whatever the equivalent in your framework is. 3) lastly, if you really need to have debug logging on and maximize throughput use asynchronous loggers and appenders. These will differ the actual blocking work. The downside is if the logging fails it can be a pain to figure out where it failed. Though that's generally not really a problem cause logging failures are almost always configuration or I/o problems which are unrelated to your code.

idk if regular log4j supports formatter statements but I known slf4j and log4j-2 do.

if i was hardcore yak shaving i'd give the logger its own thread and have the Log(String value) method just add poo poo into a thread-safe collection and a worker thread pull poo poo from the thread-safe collection

Thank you shags those are some helpful optimization tips. I need to log stuff from Thread X but absolute cannot block thread X to write to the log. I just don't know how well log4j deals with concurrency. I'll look up nlog

other things you can do if you really have severe performance requirements is have the logger log to some kind of external in memory message queue (MSMQ in .net, JMS in java) so it doesn't block and the messages are retained in the queue. I wouldn't try to write the queue inside your own program tho.

by the time i had typing class in school i had been typing for years already, but i had been doing it by looking at the keyboard. it wasnt really hunt and peck, I used the home row mostly, and i was actually really fast that way as long as i was typing straight from my head - but what i found was that i couldn't break more than about 30wpm in our typing program because i had to look up, read a few words, then look down to type them out, and i would often make translation errors like "grey" -> "gray" which hurt me even more so mid-year, i reset my profile, and started from the basics "sad sass sag" etc. but touch typing (still qwerty). everyone in the class made fun of me for suddenly being so far behind, but by the time the year was over i was the fastest in the class, something like 40-45wpm. i spent a lot of time in irc, and so by the time i was 16 or so my typing speed was more like 100-120. which is kind of insane by most standards. later on i read that dvorak was more efficient so i learned it, got up to about 40wpm, and then i got tired of having to constantly switch mentally because i'd remote desktop into a machine and be in qwerty. since most of my job in those days was remoting into machines, i just switched back for consistency then i had the wrist problems and tried dvorak again, since now my job consists mostly of local coding. now my typing speed is around 90-100 on dvorak and 60ish on qwerty. i use vim keybindings everywhere, even in dvorak, with no remapping. i just got used to using my left hand for up/down and my right for l/r. it's not that big a deal, the major benefits of vim keybindings have nothing to do with where the keys are physically well thats my story hope you liked it
