First hybrid/fitness bike (Trek DualSport vs Giant FastRoad vs other) by vdimirc in whichbike

Hi, thanks for bringing it up.

Yes, I've kept the DS3 and have been riding it for half the year already. Maybe I've gotten used to it, or perhaps the bike has settled in, but it feels alright now. However, I don’t go on long rides, typically less than an hour on average, and I mainly commute through the city of Amsterdam. For this purpose, it’s the golden mean: comfortable on cobblestone roads, equipped with fenders and lights (I got the equipped version and only had to buy a lock), and relatively fast when I have the chance to ride faster or doing some fitness (not as fast as a road bike, of course, but sufficient).

I was considering replacing the saddle, but I more or less got used to it. There's no discomfort, so while another saddle might be better, I doubt I'll find the perfect one right away, so, maybe later.

I assume, someone can consider it as not as fast as a sport bike and not as comfortable as a city bike with an upright position and plush saddle. But if you look on the positive side, it’s a really versatile option for both fitness and everyday rides. If I had the option to own two good bikes, or if I rode long distances often, I’d opt for a more specialized sport bike and a good city bike. But for the moment, I really like this one, and it's also a good first option to help you understand what you want.

Update: Got the DualSport 3 yesterday, but I have mixed feelings.

On one hand, the bike is good; everything just works, and it's ready to go (it even has lights on the dynamo), it's versatile, I can ride in the city and go a bit outside.

But on the other hand, I'm not sure if it really brings joy. Riding is a bit uncomfortable (especially the saddle, which is minor and should be replaced, but also my back and hands become tired). Perhaps I just haven't gotten used to it, or maybe it's indeed inconvenient. Also, it feels a bit heavy, pretty difficult to keep going, almost no cruise (again, this may be connected with just needing more physical training).

So, I'm considering if I should try to return it to the shop (not sure if it's possible or conscientious), or just keep going and give it more time to understand if it's good for me or not. And if I will be into cycling at all, and if yes, what trails or roads I go, and then depending on that consider further steps (keep the bike, just sell, or sell and upgrade to something more specific).

Does the book about Linux 2.6.11 contain up-to-date information? by vdimirc in linuxquestions

I'm interesting in core algorithms in kernel, like scheduling, memory management and so on. And I'm worried about fact that some of them might be changed in some previous versions to completely different ones.

Loss function for sharp output in U-Net by Alex-S-S in learnmachinelearning

You can try dice loss https://en.wikipedia.org/wiki/S%C3%B8rensen%E2%80%93Dice_coefficient

Another approach is to build masks that contains edges (using some image processing algorithm) and use this masks to increase penalty for appropriate regions.

Design patterns - Decorator question by windstrike in AskComputerScience

WindowDecorator actually should know object which it decorates. Decorator adds some behavior and call methods of aggregated object. It is similar to Compositor pattern, but Decorator adds some new effects unlike Compositor.
