Call the make_device () function in recovery_ui.cpp to create a Device instance, as shown below:
class TardisDevice : public Device { // ... all the above methods ...};Device* make_device() { return new TardisDevice();}
Compile recovery_ui.cpp
Next, we will introduce how to create a static database for recovery_ui.cpp through the previous introduction to recovery
Server in SQL 2000, the user can create a custom function, the function return value can be a value, can also be a table.
Maybe it's not clear how the custom function works. Previously mentioned in the optimizing database posts, try not to use
The server Microsoft SQL Server 2000 index does not have much change, originally thought will have R-tree, BITMAP index and so on Dongdong come out, the result very let a person lose
Hope: (
However, there are some changes, the third one has said
Server in a previous version of SQL Server, the view is not indexed, so the view is generally useless, in addition to occasionally use it to do some authority management to

Server full-Text search features a number of good improvements to SQL 2000 Full-text search.
The first is to be able to update data changes without having to rebuild the Full-text indexing index. You can update the index manually, or you can update
Server New data type
After adding four new data types to SQL 7, SQL 2000 provides two new types of data, bigint and sql_variant respectively.
In today's increasing volume of data, int ( -2^31 (-2,147,483,648) to 2^31-1 (2,147,483,647)) is used to
The server now seems to be very popular with XML, and all sorts of things are starting to support XML. The mobile suit that is good at doing things naturally is to take the lead in everything. Browsers, Office, SQL, MDAC, and

Analyze the recovery process and start with analyzing the upgrade package.The upgrade package can be generated by the make otapackage command, which is generated by makefile and the packaging script (Python.The generation rules are complex,
It is known that this problem only exists in iOS 7.0 +.
Problem reproduction:
1. For the same app, use the Product-> Archive menu, compile twice with the enterprise signature, and compile two files: app1 and app2.ipa. Their BundleIdentifier must be
These days I have been wondering how the adroid system restarts from the main system to the recovery. Different hardware platforms may have different practices. Most of the practices mentioned on the Internet are writing MISC partition BCB. However,

Of course, it will be mentioned later about whether less code is good or not.
Solve a basic problem first: How to make less code?Technical Means
Technical means are not the focus of our speech today. Because technical means are limited by the level of developers, it is extremely difficult to increase the number of technical means at once. Moreover, the business itself will limit the use of technical means.
However, let's

After getting the Nexus S, we found it was version 2.3.4. After Ota, we planned to upgrade it to version 2.3.6.
1. Normal OTADirectly choose to restart and upgrade. I was praising Nexus S as Google's second son. After the restart, I found that the robot and exclamation point icon appeared halfway through and searched for it, I found that everyone has encountered this problem.When the swap battery restarts and enters the system again, the system prompt
contains the non-clustered index key value and row identifier (RID), which points to the data row with the key value. Each rid consists of a file ID, a page number, and a row number on the page.
When the value of indid is between 2 and, it means that the table has a non-clustered index page. At this time, sqls calls the root field value to point to the root of the non-clustered index B tree, searches for the most similar value as the queried value, and finds the page number in the non-leaf node
Apple devices automatically update their own firmware. When your devices are connected to IOT platform, they are secretly downloaded in the background. Although you can use cydia plug-ins such as "noota badge" to disable "setting"ProgramA digit "1" is displayed, but the firmware is downloaded to your Apple device, occupying your hard disk space (about 1.5 GB ), I just didn't remind you to update it. Therefore, such methods only cure the symptoms. To fundamentally eliminate this kind of behavior
