Dell finally launched the long-awaited LinuxPC product today, including two desktops and a notebook, all pre-installed with the Ubuntu7.04 operating system. They are desktop PC "pcxps0000n", "DimensionE520n", and notebook "yunrone1505n ". Obviously, Dell's LinuxPC end with n for easy identification. Both DimensionE520n and xps0000n are based on IntelCore2DuoE4 Dell.

of the problem. The solution is to use JetBrains PyCharm , There is a type derivation (note to add a type annotation ). The solution is to use a strong static language. For example, I am addicted to the Rust language. In addition, Python is considering introducing the type check (mypy) [Python-ideas] Proposal: Use mypy syntax for function annotations . Python 3 supports type annotations. def func(foo: Foo) -> Bar: Bar(foo)I laughed at the python flaw. Let's talk about JavaScript. This

The first of the three major paradigms of database design is that the independent table structure must have a unique primary key to identify the table data. in the past, Microsoft's SQL Server (duo version) platform. manually encode the primary key of the table. setting it as an auto-increment column is extremely simple. the encoding is as follows: -- The simple primary key is defined as follows and set to auto-increment (only the primary key definit

[I = s] This post was last edited by pl_014 Out of curiosity about the new technology, coupled with dissatisfaction with the limitation of four primary partitions of the mbr hard disk, I recently converted a GB hard disk into a GPT hard disk, migrate the installed debian and start it from the GPT hard disk. The system runs normally and most software can run

The Fedora11 launched earlier this week is based on the Linux kernel 2.6.29, and the target start time is only 20 seconds. As early as July April, Ubuntu9.04 was based on LinuxKernel2.6.28, and the minimum system start time is 25 seconds, as the two top-level Linux distributions, the two have superior and inferior functions when performing various tasks. Let's take a look at the test and comparison of Phoronix on the two. This test platform selects 4.0GHzIntelCore2 The Fedora 11 launched earlier

Last week, Phoronix brought us a comparison between Ubuntu10.04 and Windows 7 OpenGL game performance tests. Today, Apple MacOSX10.6.3 also joined the battlefield and competed with Windows7Professionalx64 and Ubuntu10.04LST. What is the result? Let's take a look.

Ubuntu10.04 lost to Windows 7 in the Game Performance competition. Unfortunately, the latest test shows that it is also underperforming in terms of power consumption optimization. This test uses Asus EeePC1201N netbook and Lenovo ThinkPadT61 notebook respectively. The former is equipped with a 12.1-inch WXGA screen, Atom330 processor, GeForce9400MION graphics card, 2 GB video memory, and 15.4 gb5400rpm hard drive.
