1) Windows XP has bugs
Windows XP has a shutdown error, if your computer in the process of shutdown is often a blue screen shutdown, and the fault is intermittent, press the "Ctrl+alt+delete" button also has no response, then you can be sure that your system has not been patched accordingly. Please download SP1 patch pack on the patch, generally on it.

Note: This article is only to address the latest attack technology for Bluetooth PIN to remind everyone to guard against, and there is no other purpose. No one may use the techniques described in this article to do anything illegal.
Recently, a number of websites at home and abroad have published a news about the latest attack technology for Bluetooth PIN: By forcing two Bluetooth devices to be paired and listening for pairing information, an attacke

However, the woman was engaged several times during the algorithm's execution, and each time she was told that it led to a less desirable partner.As long as there is no woman to be rejected, every man is engaged to a woman, and because of the same number, every woman is engaged to the man.Now, pairing each man with his betrothed woman can get a complete marriage, and it can be proved that this complete marriage is stab

If you think of this PC machine + Bluetooth adapter as a bluetooth device, the process hcid manages the basic configuration information of the bluetooth device, such as name, class, address, and feature. In addition, when the device is paired with other Bluetooth devices Bonding/
Implementation of Pair Programming and Pair ProgrammingOver the past few days, I have been exploring Pair programming knowledge. As for the basic theory of pairing, I have already elaborated on it in my previous blog. This article mainly summarizes how to implement Pair Programming in projects and unit tests.In the project:
1. Both parties are bound to the same project team;
2. The pilot and implementer should be able to see the screen clearly before
most clients who visit the Web site cannot trust certificates that are issued using an internal CA. In fact, untrusted certificates still protect the connection, but it sends a warning message to the client when it connects to the Web site, and many companies do not want to have this warning message when they visit the site, so it is best to use public certificates for Internet-facing web sites. The Internet browser will pre-install a list of trusted CAs that will save the CA in this list to a

For example, there are three Bluetooth devices: AMOMCU_1, AMOMCU_1, and AMOMCU_1. After receiving this order, the serial port returns data:
BRSR "AMOMCU_1"
BRSR "AMOMCU_2"
BRSR "AMOMCU_3"

The basic way to attack Bluetooth
At present, some methods have been discovered to break the security mechanism of Bluetooth devices. Bluetooth devices, which are theoretically not visible, cannot be found, but that is not the case. Some software tools, including Redfang (red fangs, a hacker tool), can discover Bluetooth devices that are in an invisible mode.

principle of txt communication is the same. TXT you often use, speaking up more easily understand.LV and TXT communication need to use the "variable"/"value" pairing data mode in TXT. For example: wenben= I want to do flash message book. Here "Wenben" is a variable, "I want to do flash message book" is the value, and "=" is their pairing way, that is, the way to establish contact. OK, now we build a "lv_sh
approach, and I don't think I can see it in the future.
I think the reason for this is that this kind of process has a lot of overhead, and not many teams use it.
However, if you are developing software that is life-or-death and can be lost because of a flaw, it makes sense to look for software defects in such a structured way.
For example, you are developing software for nuclear power plants. You may need a very formal process to ensure that the final hand-over code is no problem.

equal opportunity to accept any one level of processing.The advantage is: The method is simpleThe disadvantage is: only one factor is analyzed, regardless of the differences between samples, this will increase the error, and the homogeneity of the sample requirements are higher, more suitable for large samples.Each group of randomly sampled samples can be equal or unequal, but they are more efficient at the same time, and at design time, the sample quantity of each group should be as equal as p
What is Pair programming?
In this modeProgramMembers work side by side to complement each other for development. Two programmers sit side by side in front of a computer, and use the same keyboard and mouse to work on the same monitor. Analyze, test, design, and program together.
This figure shows the Pair programming.
In Pair programming, how do two people assume roles? It should be the role of the driver and the navigator. The driver is the person who controls the keyboard input,
Introduction: What is an algorithm?How to find a stable marriage match
It is said that a book starts with a straightforward talk about gender topics, and this book will soon sell well. Fortunately, among the many topics that can be used to introduce "algorithms", my favorite one has such a relationship with the gender. If you are a matchmaker, there are several single men asking for help, there are also a number of single women also come to marry. If you already know the ranking of these girls i

1. Make sure the pairing method is correct. Some Bluetooth accessories need to press the fuselage button before they enter the pairing mode.
2. Delete the old Bluetooth configuration file.
3. Enter Settings > Bluetooth, click the settings icon next to it, and then click Cancel Pairing. Try connecting again after reboot.
4. Enter Settings > Applicat
