18! :P My rant: Cortana constantly crashes, every >4 days of use = everything becoming laggy, slow, etc.

Hi guys, I'm trying to build a painting app for my thesis that would be more "intuitive". I was introduced to Qt recently and I like it quite a lot, especially how it's cross-platform all using C++ (and QML if one wants). However, even though I'm a computer science graduate, I've always had a love-hate relationship with programming. I understand conceptually a lot of stuff but when it comes to writing it down, it's just a nightmare, unless it's visually explained and I have someone to guide me through. So I have this paintig app I'm trying to make. I was able to do so in QML because that's not even close to hard (still took me a long time ... ) but apparently QML's performance is pretty bad. So I'm trying to do it in C++. I know how events and all work conceptually, but in code I can't seem to make sense of it. To compound the problem, older examples don't work in newer versions of Qt. For example, Finger Paint| Qt 4.8[^] is the only one I found that makes use of touch to paint, but it doesn't compile nor can I seem to implement whatever I learned from it in the current version of Qt. I can certainly continue using mouse events instead of touch for the painting. I have one of those running, but what I want to do is make the painting more realistic. First by making the brush size dynamic (based on finger pressure) without using pressure-sensitive touchscreens and second by more realistic paint behaviour. So the solution to the first problem I thought of was calculating the shape of the contact area of the finger on the screen. The higher the pressure, the larger the brush size. Here is why I can't use mouse gestures because mouse is binary. I was able to find some way to calculate this in Qt but I can't find it anymore so I'm wondering if I made a mistake. I found some reference to do so in Android and Windows Phone as well. But I have no Android experience (only some Java experience) and I have a Windows Phone but I can't ask others to test without physically giving them my phone. For the paint behaviour, I found a few good research papers but considering I'm not even able to implement touch properly, I'm gonna leave that alone for now. But the basic idea would be to make a couple of layers of canvas that would store information like pigments and water and then somehow manipulate them to give watercolour behaviour, for ex

Well, isn't that the usual with current affairs ...

Mine is this one right now ArtStation - Honda S2000 Wallpaper, Khyzyl Saleem[^] ... I stumbled upon Khyzyl's ArtStation; insane stuff. On the other hand, I do calligraphy and my recent work is my grandfather's name. He put it up as his own wallpaper so I thought it would be a good share - Check it out[^]

Unfortunately for me it gets annoying. Especially when the OCD kicks in lol. It's more than the annoyance, I'm also interested in how or why it's happening on a 64-bit system. It could just as easily be the fault of the coding of Plus! when it comes to tabbed chats, but then it works fine on XP. Even opening the chat log folder first time is incredibly slow on win7 but fast on XP.

Come on guys I have my dose of blah comments whilst coding so halp plzz :p

Hey guys, I've got a Windows 7 64-bit edition on a Quad Core, and also have Windows XP installed. On XP, everything runs fine, but if I use Messenger on Win7, there's a slight problem. If I have 2 chats open in tabs (using Plus!), then if someone says something in one chatbox and I switch to see it, it appears as if the moment I switched, the person just sent the message, no matter how old the message may be. However, once I've seen the message and I switch to another chat or program window and come back to it, it's fine. It only happens when I have multiple chat tabs and messenger alerts me of unseen messages. It works fine if I only have a single person's window open (i.e. no tabs). I haven't tried switching tabs off, I suspect it will work but I'll check and report back. This also reminds me, I've noticed that if I type fast, then the letters appearing onscreen are SLIGHTLY sluggish. It's barely noticeable, but it's there. I noticed especially when I rubbed and replaced the character with a new one. On XP everything runs fine. I've posted elsewhere too, but so far no replies. Other people have also reported similar stuff but nobody has a proper solution. Any ideas? Thanks :)
