Seems crazy, but this can actually be useful to get a birdseye view of all the resources in complex scenarios. Also, nothing is keeping you from starting this service, letting it run for an hour, getting a screenshot and shutting it all down.

EDIT: To be clear, this answer addresses the question of "Is it more secure to compile my app for 32-bit x86 vs x86-64?", and does not address the question of which hardware is more secure. This is a partial duplicate of https://security.stackexchange.com/q/24829/53333 , but broader and also that question is quite old. In most ways, x64 is better. A few reasons: Because size_t is 64 bits, it's far less likely that an integer overflow will occur due to addition or multiplication, which makes some common buffer overflow scenarios less likely. Because the actual amount of physical or virtual memory that can be allocated is much lower than SIZE_T_MAX, some scenarios that might otherwise lead to overflows will instead lead to memory allocation failures, which are easier to detect. For example, if an attacker can instantiate an arbitrary number of 32-byte structs in a buffer based in the length of an input string, trying to get 0x0800 0001 of them will overflow a 32-bit size_t but not a 64-bit one while being a long (but not impossibly long) input, and 0x0800 0000 0000 0001 of them will overflow a 64-bit size_t but would also be an utterly impossibly long input. Because the address space is so much larger, higher-entropy ASLR can be used. With low-entropy ASLR, an attacker that can quickly try the same attack multiple times, or that can try attacking many victims at once, may succeed simply out of sheer luck. The smaller address space also sometimes limits what relocations are even possible for loaded libraries, which also impairs ASLR. This is the main aspect of the question linked above. Because 32-bit processes can only allocate (4GB-kernel reserved space) memory, a large but finite memory leak or expensive allocation can starve or crash them, where a 64-bit process would be fine (assuming there's enough physical RAM). However, it's not all upside. One advantage of 32-bit processes is that a misbehaving one simply can't consume all available RAM on a modern system. I once found my PC running extremely slowly, and realized it was because a chat app had a remotely triggerable memory leak and had consumed all 32GB of RAM on my PC. While in this case it wasn't actually malicious, it was a sober reminder that a bug (or vuln, even if not usable for code execution) in single misbehaving app, running in the background, can severely impair the functioning of the whole computer. If the app had been 32-bit, it would only have been able to consume a few GB, and performance of the machine wouldn't have been meaningfully impacted at all. However, the correct way to achieve this advantage is with limits and/or sandboxes. All major consumer and server OSes have ways to put limits on how many resources a process can consume, which are both more customizable than simply relying on the 32-bit limit, and can be applied to any program regardless of how it was compiled. Furthermore, sandboxing can reduce the impact of other vulnerabilities (or non-exploitable bugs).

You won't be able to fake copying through the social social network, since it's authorization, let's say, via the Contact, the user will redirect to the site specified in the annex designs (if more accurately, to one of the websites from the list of "possible sites." In Connecticut is pretty good. https://vk.com/dev/auth_sites Authorization, and you won't be able to authorise a user on another website without sending him to him.If you just want to evaporate the information protected by the authorisation, and if you have enough of a single account for it, then try to copy it through the browser, and then copy the buckets. Now, just do the GET requests to the site, feeding your URL to the cubes. If the site developer is not sufficiently experienced, this will work. Well, for the future, what you're doing is not right. Doing copies of sites with fake copying is a sin for which you can get on your hands, at least from your host. That's probably why you've been minused.

There is such a rule/recommendation: a resource should release the person who creates it.If you stick to it, option two:The facility is created by a container, which means we need to use the sharks.The object is built in the facade, which means the factory should be used and used.If the sharks don't suit you for some reason (and they can't be rolled around, the factory is a good option. The fact that you're introducing a factory, not an object, should not embarrass you.You may also consider a mixed solution: the facility is created by a container, but is released in phase. But there's a need for implementation. IDisposable a facade that might lead to new questions, plus a mix of free-of-resource styles. But sometimes this option might be the cheapest.

I've used some kind of implementation. Let us have a class that takes a lot of time to renovate. For example, we need to list many values depending on the condition of the facility. If frequent updates are envisaged, but limited access to underserved fields can be done in one way.class { private boolean isNeedRecalc; private Object field; private Object someInnerState; public updateObject(Object newObject){ isNeedRecalc = true; someInnerState = newObject; /*.... */ } private updateField(){ isNeedRecalc = false; /* ... */ } public Object getField(){ if (isNeedRecalc) updateField(); return field; } } The flag could be 1 for the entire class and for each field.

There are two choices, in my view: or you create a repository by uow.CreateReposoty, and then you have a big monolith, or still a monolith, but with a lot of properties of type IItem1Repository It1Repository { get;}, in the second approach UoW, you could use an interfais and in every service only a piece.

I don't believe you're doing that chat right now. The server has a database with registered users. And for messages, another database. Each chat matches the table. In each table, messages. At the beginning, the application sends a request to the server and comes to me. JSON rooms. In the case of a room, the last 30 messages are requested. The auto-loading of the messages takes place upstream. Your idea is ideal. Imho, that would be what any developer would have done.

The annex with the plastic architecture consists of two parts: hosta and plagins. In the NET, the host must contain an interfacing assembly in which the interface of the flame is declared. Plagin is a collection of manifests (the manifest is not necessary, but it will work faster), which contains a class that operates an interface declared in an interfaith interface. Manifest should be a file with an extension known to the host, which includes the name of the assembly required to be downloaded and, if required, specific types.When the host starts, the host must go through the directory, which is supposed to place the flames, and open all the records of the manifests. The collections in the manifests are then loaded with a challenge. Assembly.Load♪ Assembly.LoadFrom or Assenbly.LoadFile♪ If, however, the path by which the flames are loaded is different from the catalogue of the annex, this path should be added to the list of ways to search for the collection by challenge. AppDomain.CurrentDomain.AppendPrivatePath♪ Then, for each assembly, is the method GetTypes() who returns the list of types declared in the assembly. Each type shall be checked for the operation of the flame interface, typeof(IMyPlugin).IsAssignableFrom(current_type)and, if the type operates the interface of the flame, create a copy of the interface of the flame with a challenge. Activator.CreateInstance♪ As a result, a list of copies of the interface is being compiled that can be done.In your case, I would recommend in the manifests that the presentation file be listed (as I understand you mean a collection with a presentation code) and in the interface of the plagina make a characteristic that returns the counter that needs to be displayed on the deposit. The logic collection shall be placed close to the display assembly and, on the other hand, shall be loaded automatically when applied to it from the plagin user interface.

There are a lot of interaction between processes. For example, it can be arranged with a simple TCP skate. There's support in node.js. https://nodejs.org/api/net.html ♪ Qt used http://doc.qt.io/qt-5/qtcpsocket.html ♪ It's the simplest option, because there's support from the box, and on the way out, we have an asynchronous IPC. Another option could be the use of shared memory. Apparently there is. https://www.npmjs.com/search?q=shared%20memory for node.js adding support to the oa. Qt has a ready class http://doc.qt.io/qt-5/qsharedmemory.html ♪ This method is worse because it requires additional flames and it is synchronized.Let's D-Bus. Node.js is https://www.npmjs.com/package/dbus-native For this, Qt also has: http://doc.qt.io/qt-5/qtdbus-index.html ♪Of course you can still think of ways. What's better from the above? I believe that the simplest and most convenient use will be the usual TCP.

https://www.python.org/dev/peps/pep-0484/#forward-references Recommends import module instead from module import Type and apply the type in the form of strings to reduce the effects of circular dependence caused by the use of type hints:# mod1.py import mod2 class B: def init(self, arg: 'mod2.A') -> None: self.__a = arg # mod2.py import mod1 class A: def init(self): self.__b = mod1.B(self) Alternatively, if the classes are so closely connected, they can be placed in one module or carried out by another suitable refactoring case (possibly a more general type, defined for example, in a single module. mod2.typesshould be used B) See https://github.com/python/typing/issues/105

To begin with, priorities need to be defined (without grading). 1 paragraph above the others)Choose a paradigm/technology. Lots of them. MVP, Reactive, functional style, etc.To understand what will happen with the code after the annex was issued, released and forgotten or continued development. How many people will be involved in the project. If one complains, it's one thing if a big team is different.Then get a large notebook (A4 at the very time) and draw the top-level block-check of its application (lifehack pencil and straw). Then, for each block, it's a small scheme with details of implementation. Then burn to hell and start over. Change the paradigm/technology, if necessary. Repeat five times.

In the article, "a little" was wrong with definitions, out of here and misunderstood. The fact is that this article is written essentially about one specific decision, and everything else is only for general information.Integration tyre - It is primarily a communication environment that allows the delivery of messages on the basis of logical grounds. "The fingers," which means that there are no physical addresses in the messages themselves.Simple options for integrating tyres have a manual for matching logical and physical addresses. Logical addresses shall be derived from the application, its name or structure. That's enough to be called a tyre:More complex options allow for the delivery of pub/sub messages (subsent publisher).The control tyre may be built around the central node (or several nodes) where the router is scattered (see further) or be distributed as a bunch of adapters (see further) on the side of each annex with a common address base.Message route - is an annex whose purpose is to transmit messages from one annex to another.Usually, the message router can be found inside the integration tyre - but not every router makes a tyre around itself. At least we need to work with logical addresses.Also, the message routers sometimes operate other infrastructure services, such as guaranteed delivery, communications logs or format transformation.Integration lock - it's a message router that can be divided into "external" and "internal."These connections may work under the same protocol, in which case the purpose of the lock in the crash of the common tyre into segments to add non-sustainability or safety. For example, if there are subsidiaries in different cities, you can put a lock in every one that will send messages to the head office on the encrypted channel.In such a case, the overall integration tyre will be broken into segments that may continue to be limited to operation when the Internet canal falls.In addition, an integration lock may combine annexes working on different protocols, in which case it will also be an adapter.Adapter - it's a message router, whose different connections work under different protocols.Broker. - it's an elevated message router. Cool. Compities. For example, he can work with a decentralized tyre. Or do the tricky transformations as a universal central adapter.As you can see, there are no other terms. It is possible to imagine the happiness of the architect-perfectionist in the form of a mega-integration tyre built on the message router, which is a broker, a lock and an adapter. He'll be able to work on any protocol, make SQL requests, conduct XSLT-transformation and become a nightmare for any developer:I once wrote my integration lock simply because the CRIC refused to give our subsystem a second address on its integration tyre for two months. ♪ ♪There's another conclusion here: any fairly complex program can be called by any word. So, for colleagues to understand, try to call it the words used in the official title of the programme.For example, WebSphere Message Broker has the word "Broker" in his name (and deserves to wear it for his irresponsible complexity So it's called a broker, not a message router, an adapter, a lock or a tyre.On the other hand, if on the WebSphere Message Broker, a project was made to work with the SMEW, which was called the SMES, it should be called a lock, even though it is also an adapter and a message router.Or, for example, the MEME itself is essentially a simple integration tyre, and the interior spins on the WebSphere Message Broker (I've seen reports of error typical of him) - but it's called SMV, or they're not gonna understand.

To begin with, we need to figure out what the problem is when one object displays its internalities outside, and then becomes clear when it is not a problem.Incorporation and concealment are aimed at facilitating development. http://sergeyteplyakov.blogspot.com/2013/01/blog-post_29.html It is possible to focus on a minimum number of concepts at one point in time and limits the number of changes to the minimum number of modules in case of changes in requirements.When the object displays its internalities outside, it can lead to a more delicate solution. In its nature, the open class interface should be more stable and the details of implementation hidden from its clients. In this case, implementation may be replaced without disrupting the work of clients.When the open interface examines the details of implementation, in the form of open fields or even properties, this limits the ability of the author of the class to change. Type code A.B.C.D.E.Foo() has low stability, as changes in one of the five classes are likely to break it.On the other hand, not any openness reveals the details of implementation. Sometimes such properties are part of the very essence of the problem. For example, the square has the coordinates and treatment of the species: square.Position.X It could be justified.Sometimes, this rule has to be violated for another reason, for example in the development of libraries.Any complex system is hierarchical and we simply need to group the associated concepts. Same. System.out Java is such an example. We want to merge all the system operations behind some facade that will be a convenient entry point for the study. In this regard, we are not going to move out In another class, and we certainly don't duplicate surgery. PrintStream in class System♪So, as a conclusion: The Demetres law is not violated if the whole-part ratio is part of the subject area. The Demetres Act is not violated in the case of facade classes whose whose sole purpose is to provide access to certain objects.But the Demetres Act is violated if the properties displayed are the details of implementation that may change in the future.

I'll get closer to the classic architecture.How do you work with the big service?Your services have one common feature - they get a news list. A basic class--adapter♪ All the specific services will be numerical. To download the news to the descendants, I'd have gone through one of those rss-- that's 80 percent of the news sites. The appropriate adapter is not a singlton, it should be possible to create a few installs of one and the same adapter with different configurations (e.g. different addresses for rss).Adaptation design and operation - good governance Singaporewhich, for example, will getNews(query, filter). For the use of adapters, their architectural techniques are lost.Where's "right" skiing these services?I think in the news-preview counterpart, it's the direct user of the service. The menu itself is only a filter.How do you block/activate the service?The service filter (what the menu) is placed at the entrance of the getNews facade method, depending on the facade filter, designs certain adapters and uses them in the cycle.P.S. The term clacc refers not to class ES6 in JavaScript but to any way of classifying and inheriting JS facilities.

anymalTypes can be converted into a table.Then all typeID will be the keys to its objects and look like this:{ 1: {name: "Cat"}, 2: {name: "Dog"} } So you can use a simple map and assign a dop of the atribut - pictures, for example.The situation would be further simplified if the hush-table provided links to the pictures:{ 1: {name: "Cat", image: '/remoteFolder/catImage.png'}, 2: {name: "Dog", image: '/remoteFolder/dogImage.png'} } Then, for example, Murzik'a images can be used:animalTypes[animal[0].typeId].image

If you're very sad and missing many details, according to MySQL, you're moving through a targeted arithmetic, that is, you can always figure out very quickly what memory area a record is. This shall be achieved as follows.All fixed length data, INT♪ FLOAT be placed directly in the recording structure. Plus, the record contains a dynamic area with a length of 65536 Byte containing non-fixed length data, like VARCHAR, there's a NULL value. If you create a few pillars VARCHAR, which will completely choose this dynamic area at 65536 Byte, MySQL will simply not let you create new columns. (Please try to create UTF-8 VARCHAR length 65536 - UTF8-Symbol at MySQL is either 3 or 4 Bayta, depending on the code). Heavy artillery, sort of BLOB♪ TEXT The fields are stored separately at all. So you can always identify the address of your record, just make the data in memory, you know where the beginning of the memory section, and the address of any line can calculate the size of the fixed area. It contains the Dynamic site address and BLOB/TEXT- I mean.There's a great book "MySQL." Optimizing productivity. Baron Schwartz, Petr Zaytz, Vadim Tkachenko, Jeremy D. Zodney, Derek J.
