linux 屏幕录像软件 Kazam 1.4.2 发布

屏幕录像软件对于制作计算机视频教程的人是必不可少的。Linux下的屏幕录像软件有Recordmydesktop、Recorditnow等。这些个软件个人感觉不太好用。

Kazam既可以录制视频,也可以截屏,而且都支持全屏、窗口、指定区域操作,非常方便。

Kazam是一款功能强大的屏幕录制工具,提供了一个直观的,非常之简单而可靠的体验。Kazam具有局部记录的能力。

ubuntu完全卸载apache2

最近刚接触ubuntu和apache,第一次配置就被apahce搞到完全崩溃,跟着网上的配置修改apache的charset和apache2.conf以后,开始出现访问http://localhost然后直接让下载的提示:”you have chosen to open”,怎么找都没找到问题到底载哪儿,不过,还是解决了一部分问题的,总算是找到了apache2的完全卸载方法

PyroHMMvar: a sensitive and accurate method to call short INDELs and SNPs for Ion Torrent and 454 data

Motivation: The identification of short indels and SNPs from Ion Torrent and 454 reads is a challenging problem, essentially because these techniques are prone to sequence erroneously at homopolymers and can, therefore, raise indels in reads. Most of the existing mapping programs do not model homopolymer errors when aligning reads against the reference. The […]
