Practising coding can be fun, I guess

I have found recently that there are many websites you can practise your coding and get some feedback about your coding. 

I first started do Jquery, AngularJS and Javascript tutorials at https://www.codecademy.com/learn But I get frustrated when you just use if and loops in simple cases over and over again. Good alternative is Codingame where you can do the code games with 20 different languages.

I have been doing Codingame.com games and I’m now finished 91% of easy games with Javascript. The problem with my codes are that they are correct and pass most of the test but fail when there is large data set ie. they are too slow to run for the checker.

I have had difficulties with functions in past. I always was ok with coding courses when we wrote “linear code” but when it was time to use functions / classes in Java / C I was totally lost. Now I noticed that I can write functions easily and use them but my pitfall is loops. I need to optimise them and find ways to not use them when they have to go through 10000 values.

Like here is my not very sophiscated code for comparing file extension to get MIME type.

function getType(name) {    var paikka = name.lastIndexOf("."); //printErr(typeof paikka);    var mime = "UNKNOWN";    if (paikka >= 0) {        var end = name.substr(paikka+1,10);        end = end.toLowerCase();        for (var k in EXT) {            if (end === EXT[k]) {                mime = MT[k];                break;            }        }        return mime;    } else {        return mime;            } }

There other similar websites than Codingame but I haven’t tested them yet:

Making irssi texts more compact and fun

I think some messages on Irssi take too much space. I use 80x25 terminal and often use irc on tiny phone screen so I want to see a lot content on small space.

I use Myrtti’s dark winter theme.

Over the years I have modified it a little to suit better my taste and I don’t use any background image for my terminal but the background has opacity 80% to show windows beneath it. I have also tweaked my terminal’s colors a little.

Trackbar

I tried to use Weechat for a day and noticed you can modify the “trackbar” there easily. After changing back to Irssi I searched if this is possible with trackbar.pl in Irssi and it is! 

/set trackbar_string          ♡ /set trackbar_style %m

There is ten spaces before the heart char and the style is set for color magenta. I feel that using a lot spaces makes the whole feel more “spacier”. But I didn’t stop there with the unicode chars. I also changed how joins and quits are printed. I think that if you use one channel per window, you don’t need to see the channel name every time so I axed that. 

Joins Quits

/set join  %m☀%N  join: {channick_hilight $0} {chanhost_hilight $1} /set quit  %m☂%N  quit: {channick $0} {chanhost $1} {reason $2}

(There is one extra space between command and the message)

I’m thinking of reformatting host, taking out those [] which aren’t really needed. Also reason could be reformatted.

Whois

Changing days hours mins secs to d h m s. I’m not sure if this necessary or easier to read but I did it anyway. The signon message is really odd formatted but I didn’t tackle that one yet since I didn’t find it right away on /format list.

/set whois_idle {whois idle %|$1 d $2 h $3 m $4 s} /set whois_idle_signon {whois idle %|$1 d $2 h $3 m $4 s {comment signon: $5}}
