March 28--last year, Intel quietly released a small PC host, the protagonist of this article Nuc (Next Unit of Computing), which is a miniature quasi-system desktop computer, but also a traditional box-style modern computer. Nuc is located in a square box about 5 cm tall, 10 cm square, and the retail price is only 300 dollars (RMB 1863). However, you should not be misled by its miniature size or price, as t
In Oracle, we know that there is a HierarchicalQueries. Through CONNECTBY, we can easily query all the subnodes under all the current nodes. However, there are no corresponding functions in the current MySQL version !!! The following shows how to implement mysql recursive query in java: 1. Recursive class packagecn.edu. nuc. maven. MavenTest;
In Oracle, we know that there is a Hierarchical Queries. Using connect by, we can easily query all the subnode
of the cliet are consistent, you can log on to the db server through ssl, which poses a security risk.
Therefore, we need to add subject and issuer to verify that the client and server have the same key.
2. the ssl information sent to me by my colleagues is as follows. I need to use the generated two to create users:
subject: CN=nuc-bbbmysql-client.nucleus.XX.com, OU=XX Online/Pogo.com, O="Xxxxxxxxc Xxxx, Inc.", S=California, C=USissuer: E=wwtso-s
Intel NUC) running gigaboot20x6, you can boot Magenta on it like So
If you have a device running gigaboot20x6 (such as a Broadwell or Skylake Intel NUC, a mini PC host that doesn't know what Baidu is), run the following command to enable magenta on that device.
$BUILDDIR/tools/bootserver $BUILDDIR/magenta.bin
# If you have a extra bootfs image (see above):
$BUILDDIR/ Tools/bootserver $BUILDDIR/magenta.bin
Intel launches the nuc solution, which has a complete set of solutions in a small 4x4 box.
The reason for the decline of desktops is that people do not need much flexibility, and a few slots are rarely used. Why must we configure heavy interfaces and power circuits?
However, I don't think intel's nuc solution is perfect because it is based on a fan-less design that compromises space too much to meet users

Performance and battery life
HP X360 is equipped with the Intel Celeron N2820 dual-core processor (2.13GHz, 1MB two cache), 4GB RAM, and 500GB hard drive, which is similar to the typical Atom Windows 8 tablet, with a relatively limited performance relative to the core. In fact, PC Mark 7 ran a score of about 1463 points and 3D Mark scoring at around 12979, and had a very rudimentary

and 500GB hard drive combination, The screen section is mostly 19.5 inches (1600x900 pixels).
Mini PC, also using Celeron J1900 processor, 4GB memory and 500GB hard drive combination of products mostly within 1500 yuan, such as "Computer enthusiasts" in 2015 10 phase evaluation of Shenzhou MINIPC is only 1299 yuan (Figure 3). In addition, the current 19.5-inch display price is more than 600 yuan (Figure 4), the total cost of the Mini pc+ display can easily be controlled to less than 2000 yuan.
Microsoft Holographic Holographic Technology will be an important part of the 2017 Win10 major update, allowing mainstream computers to run 2D and 3D applications just like the Microsoft HoloLens headset.Microsoft's holographic holographic technology will support smaller, lower-power entertainment casinos, and WIN10 will launch a major update to support it, said Terry Myerson, Windows and device director at today's Intel LGF conference. Terry Myerson later said that the small Intel
Use of JSON, use of JSON
JSON has been widely used in projects recently. It is found that JSON and XML have similar functions and are both a data transmission format. JSON is more lightweight and easier to use than XML.
Third-party jar packages dependent on JSON:
Commons-beanutils.jarCommons-collection.jarCommons-lang.jarCommons-logging.jarEzmorph-1.0.6.jarJson-lib-2.4-jdk15.jar
Summary: The conversion between JSON strings and Java objects involves the following three situations:
(1) Conversion
console.log (' Hello, ' +username); }Exports.say = Shuo; → Exposes the Say method name in the file to the Shuo method, and other files can be accessed directly. ///main.js→ File 2 (module name 2) var person = require ('./hello '); → load module 1,person equivalent to Java classPerson.shuo (' Wenzi '); → Output Hello, WenziPerson.shuo (' Division less '); → Output Hello, division less soldiersPerson.shuo (' NUC '); → Output Hello, NUCthe node
