Microsoft launched its own Windows 8 x86 tablet SurfacePro, which will sooner or later steal the business of other PC manufacturers. Many hardware manufacturers have begun to plot countermeasures. Dell's countermeasure is to embrace Linux. Dell has just launched Ubuntu XPS13, pre-loaded Ubuntu12.04PrecisePangolin, for $1,449, $50 cheaper than Windows. XPS is mainly intended for the consumer market, but recently DellUSA once again announced Microsoft launched its own Windows 8 x86 flat Surface P

This technology should be quite mature. I have a lot of OCR software, however, I did not find a few papers with gold content, nor did I see any big bull public font. I used the pygame rendering font to generate the font, And I used PIL to cut the neat pictures to get the font. Pygame rendering font to generate font w

know that in order to cope with the increasing data traffic, shared media networks have been replaced by switching networks. This change has a direct impact on the traditional routers used for network segmentation. In view of the large traffic that spans the IP address or IPX subnet, the router has actually become the bottleneck of network transmission. The reason is that traditional routers focus more on multiple media types and transmission speeds. Currently, data buffering and conversion cap

Note:This is a comprehensive example. It can be seen from the topology that it contains devices and technologies. The following is a description of this example.1. for the internal LAN, Cisco's Catalyst 6506 is used as the central switch, and the second-level switch adopts the Catalyst 3500. To describe the Trunk, a Catalyst 2900 is added as the third-level switch, the Catalyst 1900 switch is used for terminal connection, so that Trunk can be establis
