I started my actual gig as CTO of construction group (Innovation Hub) a year ago. And it was a hell of a ride, implementing kind of a scrum-ban for project management, XP, peer-reviews, a git-flow, git commit message formats, linters, unit testing, integration tests, etc...
And it's the fun part because with the CIO we had to drive the board to do A LOT of changes in their IT/Innovation drive.
But in one year there is a lot of KPI that went up :
* Deployment: When I arrived it took three stressful days to deploy a new version of one application, once a month. Today we do it every week, and it takes three annoying hours.
* We had no test. NOTHING! Today we have 85% code coverage for the unit test, and automatic integration tests run by our CI server every day.
* We had almost no documentation. Today our code is our documentation (it automatically extracted and versioned).
* We had 0 add value in the use of git. With commit messages as "dev", "asked task", inside jokes and a lot of "fix" and "changes". Today we have a useful git, and we even use it to create our deploy changelogs (and it's only mildly annoying!).
* More important, the team is happy! They get their purpose, see betterment in their tech mastery. They started doing conception, applicative architecture, presentations, having fun.
There is still a LOT of bad things we are still working on, and trying to solve (support workflow and betterment). But seeing what they already did, I'm so proud of my TEAM! I'm a fucking asshole, workaholic, "just do it" kind of guy. But they managed to achieve so much. Fucking PROUD!!
It's 1:30 AM and I finally finished implementing a simple function after more than an hour.
Not sure if I should be upset about my stupidity or glad that I solved it.
If anyone is interested in learning Haskell I totally recommend these exercises: https://github.com/data61/fp-course
filtering :: Applicative f => (a -> f Bool) -> List a -> f (List a)
filtering p = foldRight (\a -> lift2 (bool id (a:.)) (p a)) (pure Nil)1
Have a "technical advisor" arrive 2 weeks before deadline on a year long project, only to convince my client to reject it because "we bought parts of the software". It seems he's new to npm. Btw, he says applicative instead of app.
Sydochen has posted a rant where he is nt really sure why people hate Java, and I decided to publicly post my explanation of this phenomenon, please, from my point of view.
So there is this quite large domain, on which one or two academical studies are built, such as business informatics and applied system engineering which I find extremely interesting and fun, that is called, ironically, SAD. And then there are videos on youtube, by programmers who just can't settle the fuck down. Those videos I am talking about are rants about OOP in general, which, as we all know, is a huge part of studies in the aforementioned domain. What these people are even talking about?
Absolutely obvious, there is no sense in making a software in a linear pattern. Since Bikelsoft has conveniently patched consumers up with GUI based software, the core concept of which is EDP (event driven programming or alternatively, at least OS events queue-ing), the completely functional, linear approach in such environment does not make much sense in terms of the maintainability of the software. Uhm, raise your hand if you ever tried to linearly build a complex GUI system in a single function call on GTK, which does allow you to disregard any responsibility separation pattern of SAD, such as long loved MVC...
Additionally, OOP is mandatory in business because it does allow us to mount abstraction levels and encapsulate actual dataflow behind them, which, of course, lowers the costs of the development.
What happy programmers are talking about usually is the complexity of the task of doing the OOP right in the sense of an overflow of straight composition classes (that do nothing but forward data from lower to upper abstraction levels and vice versa) and the situation of responsibility chain break (this is when a class from lower level directly!! notifies a class of a higher level about something ignoring the fact that there is a chain of other classes between them). And that's it. These guys also do vouch for functional programming, and it's a completely different argument, and there is no reason not to do it in algorithmical, implementational part of the project, of course, but yeah...
So where does Java kick in you think?
Well, guess what language popularized programming in general and OOP in particular. Java is doing a lot of things in a modern way. Of course, if it's 1995 outside *lenny face*. Yeah, fuck AOT, fuck memory management responsibility, all to the maximum towards solving the real applicative tasks.
Have you ever tried to learn to apply Text Watchers in Android with Java? Then you know about inline overloading and inline abstract class implementation. This is not right. This reduces readability and reusability.
Have you ever used Volley on Android? Newbies to Android programming surely should have. Quite verbose boilerplate in google docs, huh?
Have you seen intents? The Android API is, little said, messy with all the support libs and Context class ancestors. Remember how many times the language has helped you to properly orient in all of this hierarchy, when overloading method declaration requires you to use 2 lines instead of 1. Too verbose, too hesitant, distracting - that's what the lang and the api is. Fucking toString() is hilarious. Reference comparison is unintuitive. Obviously poor practices are not banned. Ancient tools. Import hell. Slow evolution.
C# has ripped Java off like an utter cunt, yet it's a piece of cake to maintain a solid patternization and structure, and keep your code clean and readable. Yet, Cs6 already was okay featuring optionally nullable fields and safe optional dereferencing, while we get finally get lambda expressions in J8, in 20-fucking-14.
Java did good back then, but when we joke about dumb indian developers, they are coding it in Java. So yeah.
To sum up, it's easy to make code unreadable with Java, and Java is a tool with which developers usually disregard the patterns of SAD.
Some really motivated guy.
He apparently wants to monitore his opensource application on his spare time.
His application is likely to have no users though.
But well, that guy looks like kinda montivated.
For professional purpose, guy already did monitore with newrelic.
Seems like he was not satisfied and switched to datadog 3 years ago.
But liking digging dirt, he migrated to self hosted telegraf/influx/grafana (which he likes to about)
Today that guy is not in his company but on his potatoe machine in the cloud. So he wants to be minimalistic, datadog should do.
Now you got it, random ff*** is me, on a weekend, a shinny saturday for that matter.
Actually now it is night.
Now let's start the fight.
I have datadog scripts!
But datadog be sneaky as well. datadog upgraded to v6 8=)
-> scripts ain't working. outdated.
I check the logs. Too bad!
-> datadog removed dogstatsD.log in v6!
Well I have nothing to do in my life it is too cold outside as they say. I read the (sluggy) datadoc and tries some shell command (given in doc) to upload some events to dogstatsd (via udp).
-> Nothing happens, neither in local nor in remote.
ok maybe command not up to date, so let me try some official library. datadog from python. Feels like a nice try!
-> only available for python >= 3.5. 3.4 on my good ol' jessie. Upgrading os for datadog not acceptable.
Maybe dogstatsD not started... doc says it is by default, but well, not the first time doc is wrong... I put datadog as log verbose. Guess what: as per standard: shitload of error.
Digging... kubexx, docker and whatsoever apparently preventing collector to do its normal stuff
np, I am gonna check that on github! Goog, people have the same errors. They seem to fix it by trying some settings, with. or without luck
-> I am not that warrior to check every stuff
Ok, let's stop the datadog events, it works. It does not anymore. You know that sentence. We all know it.
Still not enough!
How about testing that uber super nice feature of v6. The logs. After all I want to make events out of my applicative logs.
How about reading the log again. Configure the yaml log as they say. Done. Make some pattern. Read the best practive. Done. Configures the yaml. Done. Now testing.
-> remote datadog interface be like: no logs for you dude you need to pay
Fuck datadog, fuck that v6 version, good old tail -Fxx | someaggreate.js|sendmail will do...
