reflection It delays static binding during compilation to dynamic binding during runtime. Reflection brings a lot of design flexibility, but dynamic binding has a greater impact on performance than static binding. 1 type. invokemember 2 contructorinfo. Invoke 3 activator. createinstance (type) 4 activator. createinstance (assemblyname, typename) 5 assembly. createinstance (typename) The fastest performance is 3, the slowest is 4 Suggestion: 1. If possible, avoid using reflection and dynamic bi

performance, slightly worse than Nikon, but not far away Tamron 70-200 6 K, new head, good performance Nikon 70-300 VR 3 K, small aperture, but lightweight and easy to use Nikon 70-300, the choice of the poor, not recommended If it is not particularly necessary, it is recommended that the 2.8 aperture lens, the factory can not be on the deputy factory, the aperture is too small, the focal length is not very easy to use, if the funds are really limited, consider VR's dog head. Fixed focus:Ni

challenge for us. So what are the driving force behind the rapid growth of computers? At the top, there is a 0.28 million, which is what we call magnetic memory. We can store all the information we have gained for a lifetime on several disks. Second, we have not considered this. We can further improve the purity of glass. If we add some routes in the past, this will increase the time. However, what I want to say is that bandwidth is no longer a scarce resource, the latency can be improved throu

. If you need to sign j2se. Jar code, we recommend that you purchase the thawte Java code signature certificate because it is cheaper than Verisign. If you want a Java code signature certificate that is cheaper than the thawte Java code signature certificate, you can purchase the wosign Java code signature certificate, wosign Java code signature certificates only support Java j2se 1.5.008 or later versions.

satisfactory result is that we can discard the if-then Syntax of Java in the arc, because we can use it elsewhere. Art Designers don't need to deal with these complex syntaxes, because simple syntaxes are enough to do a lot of things. They don't need to think about these puzzling things in string definitions. Param Singh, Senior Marketing Manager of javafx, told me Sun wants early javafx users to be Java developers and skilled art designers. Singh said that the visualization tools prepared for

version 3.6.27 is hundreds of kb. 3.Green SoftwareAnother feature of SQLite is green: its core engine does not rely on third-party software and does not require "installation environment" (such as Oledb ). Therefore, it can save a lot of trouble during deployment. 4.Single fileThe so-called "single file" means that all the information in the database (such as tables, views, triggers, and so on) is contained in one file. This file can be copied to other directories or other machines. 5.Cross-pla

, ActionScript, java or PHP code These solutions are characterized by the use of existing IDE To improve the coding of popular programming languages such as C # source code, especially the support for strong types, refactoring and testing, developers are allowed to write C #, which is converted from a tool to a JavaScript code that can be directly executed and formatted. In addition to fully utilizing IDE's coding support for popular languages, another benefit of this type of solution is that J

much less damage to the disk. Conclusion and some additional words Now, can we draw some conclusions? I will leave it alone. Readers should be able to make their own judgments. I have no doubt that the people who write these hard drive maintenance tool programs are geniuses, or even those who crack other people's program engines, but everything has its own objective rules, it will not be transferred with the propaganda and will of some people. Software can achieve many functions, but in the sam

Bcache is the Linux kernel block layer cache. It uses SSD as the cache of the HDD hard disk to accelerate the operation. HDD disks are cheaper and have a larger space. SSD is faster but more expensive. If you can have both of them, isn't it easy? Bcache can do this. Bcache uses SSD as the cache for other Block devices. Similar to the L2Arc of ZFS, bcache also adds a write-back policy that is irrelevant to the file system. Bcache is designed to work in

Many developers often do not consider the char and varchar types when designing databases. Some developers do not pay attention to them because the storage price is getting cheaper and cheaper, I forgot some of the basic design theories and principles at the beginning. This reminds me of the young people who have moved away from their hands with a wave of RMB. In fact, I want to be a human or a human, devel

Currently, the most installed systems on servers are Windows, Linux, and FreeBSD. In terms of security:Windows is a familiar and easy-to-install and configure system, but its security is relatively poor. Once attacked, the entire operating system and all your user accounts will be paralyzed. Linux and FreeBS have relatively high security. If a Web server is cracked by hackers, users on this Web server can still use it. Hackers who break your Web server may still be unable to obtain the root acc

to the network interfaces of each container and lock all accessible points. Compared with the distributed service environment, the mainframe has a high resource usage. Linux processors on the mainframe can handle workloads immediately and efficiently. Running Linux workloads on System z is cheaper than running Linux workloads in a distributed service environment, because the mainframe software protocol corresponds to the processor kernel. Virtualizat

The MKMapView memory is released. Memory release of MKMapView By Wu xueying - (void)dealloc { self.mapView.showsUserLocation = NO; self.mapView.userTrackingMode = MKUserTrackingModeNone; [self.mapView.layer removeAllAnimations]; [self.mapView removeAnnotations:self.mapView.annotations]; [self.mapView removeOverlays:self.mapView.overlays]; [self.mapView removeFromSuperview]; self.mapView.delegate = nil; self.mapView = nil;} Although not all the memory can be released, so

only cheaper than the DVD + R, and better compatibility (for earlier DVD players ). If quality is not required, the dvdrecording 3.5 developed by Ulead is a silly software in this field, and all the above steps can be easily completed. I would like to briefly introduce the hdvd production process here. Of course, I do not encourage everyone to do DIY, but it is understandable if it is used to organize home audio and video materials. From the hdvd p

Unsurprisingly, and unexpectedly, Stack overflow still uses Microsoft's products heavily. They think that since Microsoft's infrastructure can meet demand and be cheap enough, there is no reason to make fundamental changes. And where needed, they also used Linux. At its root, everything is for performance.Another area of concern is that the Stack overflow still uses a vertical scaling strategy, without using the cloud. They use 384GB of memory and 2TB of SSDs to support SQL Servers, and if you u

Conversion: differences between char, varchar, text, nchar, nvarchar, and ntext in SQL Server Many developers often do not consider the char and varchar types when designing databases.

In the past, IC card-type electric energy meter and one card (water and electric heating) systems were used with contact IC cards, which had weak anti-interference capability and outstanding quality problems, especially open read/write windows. It is vulnerable to external attacks. The hitag RF card and its supporting read/write modules completely solve the above problems. The cost is only slightly increased, but the product quality is greatly improved. Hitag is used. It is the same as the Atme

service fee is cheaper than the transportation fee to Hong Kong, I think it is cost-effective ." However, she said that she seldom heard of the appeal cases. However, she also said that although there are no other conditions for Mainland residents to apply for insurance in Hong Kong, everyone can buy insurance in Hong Kong. However, Hong Kong insurance is generally higher than that in mainland China and is suitable for families with a relatively high

1. The first floor is generally slightly wet, with poor privacy, but it is also cheaper. 2. Generally, the whole rent is relatively cheap. It is best to seek a friend to rent the whole house together. There are many intermediary services, and I love my family and chain home. Can the app, mushroom rental, and house and real estate agents on the house and house owner take you to the room? The service is good, which saves you trouble and allows you to

another topic outside of the scope of software Speed Optimization; however, the interaction of software Speed Optimization and hardware optimization must always be considered. Jump to top of page Why optimize software? This is a critical question. You may think: Our MERs do not care about speed. They are happy with the performance they get. Processors get faster all the time. Optimizing costs development time, I rather use a faster machine (when bundling HW + SW ). Compilers are so good to
