Many operators have the account and password of the Third-Party website. However, if the operator leaves the company, the password may be lost or leaked. So I need to...

Defends against internal attacks
The so-called "easy to hide, difficult to defend against" is relatively easy to guard against external attacks, and it is very difficult to guard against malicious attacks from the internal network of the Organization. First, some important data information is easily
try to keep your program running, so it's likely that onterminate won't be called. 5:memoryleak in Java memory leaks are only, some (some) objects are no longer being used should be recycled by GC, but there is an object holding a reference to this object to prevent this object from being recycled. For example, we typically create a view TextView TV = new TextView (this), where this is usually activity. So this textview holds the reference to the activity. Here's a picture (copied in Google IO
, therefore, IDE (including Subl) cannot be used to improve coding efficiency. it is a bit painful to develop and maintain this project.
2. the following http forwarding method is widely used internally for decoupling:
// User edits in the CRM subsystem are forwarded to $ return = $ this-> format_query ('/user/edit', $ _ POST) under user/edit in the S system ); $ this-> _ return_json ($ return );If no one asks me, I will not ask myself.
Looking at the rough view, this is not so much a leak as
object references, so the memory of the entire activity is leaked.
Generally, when a user turns the mobile phone, Android will call the oncreate () method again to generate a new activity. The original activity should be recycled by GC. However, if an object such as a view has a larger scope than this activity (for example, there is a static object or we include the reference of this view in the application ), at this time, the original activity ca
avoids most of the leak detection algorithms. Because we have not actually leaked any visible elements, and because the leaked object is too small, you may not pay attention to this problem. In order to leak our example, a script function pointer must be included inline in the dynamically created element structure. After we set the relationship between these elements, this will expose the internal temporar
If I get the api_token,user_token and so on through the grab bag and so on all parameters and header, that in a short period of time, I directly with the parameters I obtained, validation rules passed, I can not use this interface? The only way a person can think of is to shorten the time of token verification. Don't know how the great gods solved this problem?

Big Data has been very popular in recent years, but privacy has become a concern. Big Data collects people's highly private data, such as medical records or shopping records, and then uses a separate identification program to be anonymous. In this way, people do not have to worry about personal privacy leaks. But is it really that simple?
Anonymity in the big data era is not 100%

I recently used the Instruments tool and found it very helpful for tracking memory leaks in the game. Since I discovered that Instruments are so useful, I think writing an article about how to use it to track memory leaks can also help others.What is memory leakage? Why do I need to care about memory leakage?... This section is omitted...Visit Wikipedia to obtain more information about memory leakage.How do I know that the memory has been leaked?Some
effort on knowledge management over the past two years. However, the company's senior management found that it was easier for employees to acquire knowledge after all their knowledge was collected, however, it also makes it easier to leak external knowledge. In the simplest way to verify, open Baidu Library, enter the name of their company, you can find a large number of documents in Baidu Library, these documents are even project information that is only half a month after they are closed.

If this parameter is specified before the connection is returned to the caller, the query must be an SQL SELECT statement and at least one row of records must be returned.Validationquery = select 1# Check whether the connection is retrieved from the pool.

, while dealloc needs to be counted as 0 if it is called. These two conditions are added, leading to counting locking and Memory leakage.
First, let's talk about how to find it.
1. First, use analyze build to view the memory warning in the category.
In general, we can find that the local variables forget the release, or the release is interrupted midway through.
2. Use the leak monitoring in instruments directly.
After applying for the memory, there is no pointer pointing to this me
/destroymenu. (There are multiple resource allocation functions and only one release function. For example, sysallocstringlen can also be used to allocate BSTR. In this case, multiple allocation functions need to be intercepted)
In Windows platform, there are three commonly used tools for detecting Memory leakage, the built-in detection function of ms c-Runtime Library; External detecting tools such as purify and boundschecker; use the Performance Monitor provided by Windows NT. These three tool
generally use functions such as malloc, realloc, and new to allocate a block of memory from the heap. after use, the program must call free or delete to release the block. Otherwise, this memory cannot be used again, so we can say this memory is leaked. The following applet demonstrates heap memory leakage:
Void myfunction (INT nsize)
{
Char * P = new char [nsize];
If (! Getstringfrom (p, nsize )){
MessageBox ("error ");
Return;
}

the running period). After use, the released memory must be displayed. Applications generally use functions such as malloc, realloc, and new to allocate a block of memory from the heap. after use, the program must call free or delete to release the block. Otherwise, this memory cannot be used again, so we can say this memory is leaked. The following applet demonstrates heap memory leakage:

instruments tools are required.
1) first, we need to reproduce the problem and find out which operations are prone to memory leakage. It is mainly determined by some tests and reasoning, such as identifying which operations are repeated, and the memory growth is obvious or Crash occurs.
B) use the instruments tool. Instruments injects some code into the program during program running to dynamically detect memory allocation and leakage issues. Run-> Run with perfomance tools-> leaks. Is the resu
