The last article "you wrote Try...catch really necessary" aroused a lot of friends of the discussion. This time I found another problem in code review, that is, someone intentionally or unintentionally wrote the return null such code, for example: Public User GetUser (string userName, string password) { if (/*for some reason*/) return null; return new User (); Is there a problem with wood?In my opinion, there is no good reason

developers are concerned about. I'll talk about what kind of things should be recorded at this level. TRACE More detailed information is only used in the development phase. You may also need to focus on this information for a short period of time after the product goes live, but these logs are only temporary and should eventually be turned off. The difference between debug and trace is difficult to distinguish, but if you add a line of logs and then delete it after the development test, the

I'm sure the beauty of algorithms isn't perfect, but I've always treated it with a pretty serious attitude. In particular, I would like to be able to continue to improve it through the prize-catching activities. In fact, I've found several errors, but I didn't add them to the errata, a

, you can summarize it through practical operations; without experience, you can accumulate it step by step; without social relationships, you can weave it at 1.1 points. However, it is the most terrible thing to do without dreams or ideas. !People must have a correct direction. No matter how cool you are, no matter how wise you are, no matter how much effort you have spent, if you do not have a clear direction, you will be lost and gradually lose fighting spirit, if you forget your original dre

The interface between the kernel and the user state is simply too much, and sometimes it is inappropriate to divide them into a ranked, such as the infamous IOCTL, which, once it stinks, does not say well. Sometimes it is not as bad as it is imagined, most of it is because people misuse them, and then a master says it is not good, and since then people have gone with the master ... For the IOCTL, corresponding to the socket type file descriptor, is ge

Watch Bertin demonstrate the distinct graphic opportunities that the retinal variables provide for solving the same visual Problem: After addressing fundamentals, Bertin dives into theory. He covers the three questions every visualization should answer, as well as the three functions o

Also, as a developer of a client who wants to process these markup fragments, you should be able to take full control of your template. and the template engine (Smarty), Traffic (Velocity) and ASP these server-side content you do not need to know, do not care about those "noodle Code" (spaghetti): For exampl

virtual functions have a performance penalty over regular member functions, they are often the most efficient way to implement a concept such as polymorphism where the alternative wocould be large switch statements (not to mention the benefits of the object-oriented encapsulation ).Summary:Use virtual functions to implement polymorphism.Virtual functions have overhead, so don't need to use them unless you really showould.A destructor in a base class shoshould always be virtual if polymorphism i

blue thing? Not all of us can visualize a 75 pixel width, or know when we're looking at one, so to help out 'I ve got ded a blue, 75-pixel-wide image in all of the examples. it's easy to spot because it's blue and says "This is 75 px wide. "in all cases this image is applied as a background to the DIV holding the example and so takes up no space. it's there just to make it easier to see when a false margin is being applied.Let's start with something we know First a review-the

infamous rootkit, due to its ability to hide and run programs efficiently. for more detail about the inner-workings of rootkits, please refer to my article"10 + things you shoshould know about rootkits." To become part of a botnet, you need to install remote access commands and control applications on the attacked computer. The application selected for this operation is the notorious rootkit because it can hide and effectively run programs. For more

we've got in imagenet testing, imagenet localization, coco Detection and Coco segmentation.1.IntroductionThe deep convolutional neural network [22,21] leads to a series of breakthroughs in image classification [21,49,39]. The deep network naturally integrates low/medium/Advanced Features [49] and classifiers in an end-to-end multilayer way, and the "horizontal" feature can be enriched by stacking layers (depth). Recent evidence [40,43] reveals the profound importance of the network, and the maj
