to use the old peaches and so on to make the installation disk, but using such as Image Writer (also known as Win32diskimager) or Ubuntu under the UNetbootin (need to install) to make the boot disk. For example, I use image Writer to ubuntu-14.04.4-server-i386. The ISO is written to the U-disk, thereby serving as the installation disk;Of course, this approach also has flaws:The entire U-disk is no longer available under window unless formatted;And with the old Peaches to do the installation di
The newly installed version of ubuntu14.04, which copies the previous 12.04 normal use of Eclipse to 14.04, when you start Eclipse, when you enter the code, a point appears "." The prompt will restart automatically.JDK is 1.7.After finding out, we need to modify the following two places:(1) Confirm project-> Properties, Java Compiler, Compiler compaliance level is 1.7The first one defaults to 1.7, so just modify the Eclipse.ini file.(2) Modify the Eclipse.ini fileModify the content, change the-d
Let's look at the exact words in the Java API documentation:当扫描器抛出 InputMismatchException 时,该扫描器不会传递导致该异常的标记,因此可以通过其他某种方法来获取或跳它。 这是java API文档中的原话。In fact it means: "'If you enter the a character when the Nextint method executes, and you do not successfully parse an integer at this time, your input will not be ignored. Because it might be able to be parsed by other formats.Then your program entered a, an exception, number is assigned a value of 100, start the next loop, but the

Since Unity's destroy method is delayed, that is, he is not immediately destroyed, that is, you call the Destroy method, in fact, he still exists, but in the next frame, he did not , If you want to perform an operation to empty the sub-object under a Gameobject object and add a new sub-object, the first destory and then add the method is not possible, then we can take the previous object to hide and then add it to a destroyed array, so that we can start adding new objects. , and then focus on th
Today, record the problems you encountered before: Project deployment in window login can be completed quickly, after deployment to Linux, the first logon process becomes very slow.By looking at the system log, the discovery time is mainly consumed in the creation session, and is located to the SecureRandom initialization problem, continue to view, found that the session ID is created as a UUID, here, the person familiar with Linux will understand the problem.Java's UUID relies on the Securerand

Os:ubuntu Linux 12.04I manually updated the Firefox browser the other day (see http://www.cnblogs.com/yzsatcnblogs/p/4266985.html), but then when I opened the browser, there was no Firefox icon on the launcher. This allows us to no longer open the minimized browser ... Nor can you quickly open the browser. So I learned how to add an icon to the launcher and change the icon pattern. summarized here.(1) Click on the gear mark in the upper right corner. Select "Launch Application"(2) Click "Add" in

specific object, which is actually a built-in property of the current function. Arguments is very similar to an array, but is not actually an array instance.The length of the arguments object is determined by the number of arguments, not the number of parameters.Finally, we will use several questions to consolidate the following:varFullName = ' John Doe '; varobj ={fullname:' Colin Ihrig ', prop: {fullname:' Aurelio De Rosa ', Getfullname:function() { return This.

we often call the St table, which has been preprocessed for O ( Nlog (n)), compared to the normal line segment tree ( Even if someone will think of the zkw Line tree ), its query only requires O (1), and the algorithm's constant is very small, and more importantly, it is better than the normal line of the tree to write more. (PS: There is actually a preprocessing time for O (n) algorithm-constrained RMQ, but some trouble, temporarily not introduced, interested students can see for themselves)It
