Conversation I had with a coworker today:
me: When transferring an object from C++ to QML you have to set the parent of the object. If you don't QML thinks it can just delete this object.
coworker: So if you don't set the parent of the object then the orphans get Anakined?
me: Yes1 -
My favorite OpenSource project is Julia (www.julialang.org). As a physicist, I could never really befriend myself with OOP. With Julia I can write beautiful Code, which I also understand (with full UTF-8 support).
In Python you write pseudo code in Julia you write math.
In Addition, there is an optional package on Github for every fuck which can be handled by the integrated package manager (like using QML, Distributions, Databases, HTTP Server, and so on...)4 -
Rant && SPAM alert!
I'm learning QML, to create plasma widgets and I wasted all the fucking day fighting with layouts and trying to understand why the settings window was not rendered (now it's rendered but I still don't understand why it wasn't before, the code is the same!)
so at the end of the day I ried to apply what i learnt in a fresh new widget that shows (some) PiHole statistics from its API.
on first run:
it runs fine, no errors... ok let's do some tests... turn off network, whole DE freeze WTF!?! one widget error (network error in this case) can freeze the whole DE.
restarted plasma, FIXED the bug (debugging process basically is:
try something - freeze - restart plasma - repeat
),
No more freeze!
if you're a KDE and pihole user and you want try my widget:

P.S: I'm adding right now a switch to quickly enable/disable pi hole over API directly from your desktop. i will push tomorrow.4 -
TeamLeader : "Come two seconds"
TL : "I'd like you to check that out when you do that"
Me: "But it's your job to do this"
TL: "Yeah, but I'd like you to just check in case I forgot"
THEN DO YOUR FKING TASK PROPERLY WHATS THE POINT IF YOU FORGOT AND I DO IT

been exploring the options for cross platform desktop app, and i found :
java : both awt and swing look ugly, i really like OOP of java, and the way projects are organized is easy to scale, but i need to deploy the jdk, and the speed on gui apps isn't that great
C# : (.net/ mono, i can't grasp F# and vb is stupid) looks native on windows, not so much alien on both linux/mac, and being a java cousin is a pro, i found the Eto library for mono even looks more native on *ix than winforms
wxwidgets: for C/C++ so far this looks like the best option for total native feel and performance, but man i fucking hate C code, and this looks a lot like C code, even with proper native Cpp support, maybe i should dive deeper in it
GTK+ : did any one mention C code ? because this mother fucker is plain C with macros all over the place, it made me realize why wx is promoted as Cpp friendly, i doubt I'll use this
tcl/tk : even tho ive never wrote a single line of tcl in my life, the tk lib is the default ui for both python and ruby on all supported platforms,
and i really love ruby, and Python is Usually a joy to work with
Qt : this by far looks like the best option, proper OOP in C++, bindings for python (ruby binds are outdated), almost native look and feel on supported platforms, and even has a gui builder in xml or json/js (qml) however i bet I'll use such a thing, the building tho depends on an external preprocessor "moc" and some wicked macros, also makes working with templates a fucking mess, and the heavy dependence on QObject inheritance makes integrating external libraries a bit more tiring, the signal slot system makes more sense in python than in C++, since it makes me confused about the flow of the code
lazarus: is a freepascal implementation that looks and feels like delphi, not so much for native look and feel, but good performance and easy language to handle
electron : this fat mofo is fat, it's the slowest of all options, if i want an html app, I'll just compile a stripped down webkit and deploy that
what do you think ? and did i miss something ?17 -
Holy f-ing hell!
Why do the small things have such fucked up corner cases?
This is very likely a giant bug with Qt, but how does this even happen?
I am using Qt with QML and sending data to a database on the backend. I call functions in QML from a Date JS object (property actually, but it calls functions) to set the date as a QDate. This is stored in the database as yyyy/MM/dd. This is fine. When I read the date out I convert it back from string to QDate and send this object to QML. Which then converts this to a Date object in JS in QML.
But at the point where it converts from a QDate to a Date object it loses an entire day. Seriously? You didn't gain a day going from Date -> QDate, but you lose a day going from QDate -> Date?
How long has QML and Qt been around? At least 5 to 10 years. How has this bug lasted this long? I don't want to do a bug report. I will, but I don't want to .6 -
So I was playing around with JS inside of QML (Qt). I wanted to turn a number into a string and then modify individual chars based on certain criteria. Then I would convert back to a number. Should be simple right? Well JS would not let me write to the indexed element of the string. What the actual fuck? I need to drop to C++ to do actual string manipulation? I ended up looping the string and turning it into an array and then a join back to a string. There is probably a better way to do this in a more modern version of JS, but I am now starting to see why JS is a pariah on here. It has some quirks that make you question your devlife choices.
What was I working on? Some stupid crop circle thingy. I was trying to use the QML Canvas to draw some "simple" crop circles. So I started with this crop circle:

The result ended up being kind of a swirling crop circle thing. The static image was too boring:

And yes, I was too lazy/cheap to license the screen capture program.7
