   • What are the main disadvantages of Windows pipes for inter-process communication?

     Top Answer

     Answered Feb 08, 2013 · 14 votes

     You can create two-way anonymous pipes using CreatePipe() Win32 API call, so piping input/output is not the only way. You simply get a new file handle you can give to the other process.

     Anonymous pipes are based on shared memory, but do not support asynchronous operations (through ReadFileEx, ReadFileWrite). Performance issues (disadvantages) are thus 1) synchronous operation, 2) memory copying, 3) interprocess synchronization. Generally, "raw" shared memory (memory mapped file without an actual backing file) and named pipes will be faster, and sockets and Window messages will be slower (than anonymous pipes).

     You cannot use I/O Completion Ports (IOCP) with anonymous pipes, instead you'll have to "poll" the pipe, incurring extra context switches. In addition to serializing the data, the serialized data has to be copied around in memory, as you cannot write directly to the shared memory. One process also has to wait for another, implying that the other process has to signal an interprocess synchronization primitive. Performance depends heavily on the size of the messages (ratio of read/write calls to amount of data sent), because for each read/write the process has to make context switches and possibly spin/sleep.

     All methods except "raw" shared memory require memory copying and some sort of interprocess signaling (synchronization), so the main disadvantage of anonymous pipes is synchronous operation. You'll hit the ceiling when transmitting large number of messages, when the CPU spends most of its time doing context switches.

     Performance-wise, named pipes are better because you can have worker thread(s) processing async notifications using IOCP, and can even receive multiple messages with one call, thus reducing the API overhead. If making your own components, the extra trouble from giving a name to the pipe is well worth the trouble (and you can even connect across networks). Later Windows versions implement special routing for local sockets, which also do support IOCP.

     The fastest method would be to use shared memory directly, but then you will have to take care of interprocess synchronization yourself. It's possible to implement lock-free pipes yourself, but in case you're not constantly transmitting data, you'll still have to use synchronization primitives to notify/wake the listening process up.

     Also note that using files does not imply that you would be limited by disk speed, as you can use memory mapped files and even with normal files, the cache manager handles the reading/writing. The other methods (RPC, clipboard, etc) are based on these "standard" methods, which means they'll just add some extra layer of protocol and are meant to be easier/more helpful, or more suitable for some programming environment (but not to be faster).

   • What are the advantages and disadvantages of refactoring code smell in software quality?

     Top Answer

     Answered May 18, 2017 · 3 votes

     Although refactoring does not add features or functionalities in a software system, it is sharp weapon for developers in their maintenance activities. It makes a software system easier to understand and cheaper to modify without changing its observable behavior by changing its internal structure.

     The purposes of refactoring according to Martin Fowler (Father of Code Smell) are stated in the following:

     • Refactoring Improves the Design of Software
     • Refactoring Makes Software Easier to Understand
     • Refactoring Helps Finding Bugs
     • Refactoring Helps Programming Faster

     Specially for long-term software, it is essential to refactor the code in order to make the software more adaptive. However, you definitely do not perform refactoring tasks, if it exceeds your budget and time. In essence, stop refactoring when you -

   • What are the disadvantages of the ECS (Entity-Component-System) architectural pattern, compared to OOP (or other paradigms)?

     Top Answer

     Answered Dec 23, 2019 · 11 votes

     Here's a few points I gathered from my research:

     • Systems are very dependent on their ordering. Introducing new systems in between already existing Systems can be a challenge.
     • You also need to plan ahead your data as much as possible, since they will potentially be used by a LOT of systems. Changing the content of components could potentially break quite a few systems.
     • Although it's easy to debug the flow of a system, it's also harder to debug single component changes and not have a global view of what happened to the entity across all it's components. I'm not sure if Unity introduced new debug features for this.
     • If you're planning to use ECS in your team, introducing a new paradigm to devs that are not familiar with it could be a challenge. The onboarding time could be longer with more overhead.

     Hope this gives you a good starting point.

   • What are the disadvantages of targeting the JVM instead of x86?

     Top Answer

     Answered Jun 14, 2010 · 4 votes

     Targeting the JVM is a pretty tried and tested approach. The fact that Clojure, Scala, JRuby and many other languages have done so successfully should give you some reassurance.

     My view overall is that the JVM is probably the best target at the moment for new/experimental languages, particularly if you hope to achieve cross platform capability while taking advantage of a truly fantastic JIT compiler and a wealth of very powerful libraries.

     Having said that, the main disadvantages you may encounter targeting the JVM are in my opinion as follows:

     • Lack of tail recursion support at the bytecode level. There are ways around this (e.g. see Clojure's "recur" special form) but it is annoying for some language implementations, particularly functional languages. Will probably eventually be fixed in future versions of Java.
     • Slightly obvious, but you need a JVM installed on your client. Usually not a problem nowadays, but there are still cases where this can be tricky.
     • Primitives (int, long, float etc.) in Java behave differently from the rest of the object system. Again you can work around this but it is some extra hassle for language implementers.

     Some potentially useful/interesting links:

     • ASM bytecode analysis and manipulation framework. This is a great tool, I believe it is what what Clojure uses under the hood.
     • Clojure source code

   • what are the disadvantages of H264?

     Top Answer

     Answered Dec 13, 2010 · 7 votes

     Encoding and decoding complexity: H.264 encoding and decoding is more computationally complex than some other codecs such as MPEG-4 Part 2 (DivX, XviD). However, the compression performance of H.264 is significantly better than these so it depends on what is more important to you.

     This is becoming less of a problem as more devices are including hardware support for H.264.

     Error Resiliency: There are some things in H.264 to deal with bit errors, but often they are not used and a single bit error can still have a catastrophic effect. From what I have seen in my study of video codecs, error resiliency seems to being pushed to another layer in most systems. That is, the video codec is designed for maximum compression, and another layer is added on top of the video data to take care of bit errors. That way those who don't need the error resiliency don't pay for it with lower compression rates.

     A common example of this is the DVB standard which uses MPEG-2 or H.264 coded video inside an MPEG-2 Transport Stream that contains a forward error correction scheme.

     Licensing and Royalties: I am no expert (or even reasonably knowledgeable) in this area, but depending on your use case, you may have to pay some kind of royalty to encode to H.264 legally. See this.

     Other than these, I really don't see any other disadvantages of H.264. It seems to be the state of the art for anything from internet quality streamed video to Blue-Ray HD video.

     I can't really comment with regards to the last question (packet/circuit switched networks, interworking between vendors, etc.) since I have never actually built a hardware system to work with H.264. I will say that as long as the encoder creates a valid H.264 stream and you have a decoder that fully implements the standard, you should have no problem getting things to work together. This is the whole point of having a standard.
