Husband of missing Oakland mom arrested on suspicion of murder

(10-10) 16:47 PDT OAKLAND -- The estranged husband of an Oakland woman who has been missing for more than a month was arrested today on suspicion of murder.

Hans Reiser, 42, was taken into custody at 11 a.m., hours after Oakland police and FBI technicians searched his home in the Oakland hills. His estranged wife, Nina Reiser, 31, has been missing since Sept. 3, when she dropped off the couple's son and daughter at his home on the 6900 block of Exeter Drive.

Nina Reiser's minivan, with groceries from Berkeley Bowl inside, was found several miles away Sept. 9 in Oakland's Thornhill neighborhood.

"I guess that the police are not expecting to find Nina alive. I'm very sad about that, terribly sad," Shelley Gordon, Nina Reiser's divorce attorney, said today. "I just pray for the children."

Anthony Zografos, Reiser's boyfriend, said, "I have no thoughts. Until they find Nina, I don't know what to think."

Authorities did not immediately say today why they believe Reiser is dead.

Monday's search was the second at Hans Reiser's six-room house, located on a winding street off Skyline Boulevard. In mid-September, police spent several days searching the home where his mother, Beverly Palmer, also lives. They brought in a cadaver dog during that search.

On Monday night, police with the missing persons unit returned with a homicide investigator and the FBI's evidence response team. Police removed items from the home, including what appeared to be a door and a rolled-up carpet.

Police used a search warrant Sept. 28 to obtain a DNA sample from Hans Reiser, who has declined to talk to police.

His lawyer, criminal defense attorney William Du Bois, had initially said Reiser would be available "to both the press and the police." But Du Bois later said Reiser would not talk to police because he was upset about the search of his home and didn't trust investigators.

Du Bois complained today that police had not allowed him to meet with his client after the arrest. He said investigators were keeping Reiser in isolation.

Police made the arrest based on circumstantial evidence and have not found Nina Reiser's body, Du Bois said. "I have no idea what the circumstantial evidence is," he said. "When I hear what the evidence is against him, I'll make a decision as to whether he'll talk to them."

The Reisers were married in 1999 and frequently traveled to Russia, where she was born. They separated in May 2004.

Nina Reiser filed for divorce three months later, citing irreconcilable differences and saying their children "hardly know their father" because he was out of the country on business for most of the year, according to court records.

Nina Reiser, who was trained as an obstetrician and gynecologist in Russia, was granted custody of the children. The divorce was not finalized.

Hans Reiser has prided himself in interviews on having been accepted to UC Berkeley at the age of 15 after dropping out of junior high school. He attended the university off and on before graduating in 1992 with a bachelor's degree in systematizing, an individualized computer-science major. He operates his own business, Namesys, from his home.

Nina Reiser was granted a temporary restraining order against her husband in December 2004 after she reported that he had pushed her and was abusive to her. A year later, she agreed not to seek a permanent order.

Hans Reiser was accused earlier this year of failing to pay medical and child-care expenses as ordered by a judge, records show. He pleaded not guilty Aug. 25 to a civil contempt charge and was scheduled for trial in October.

Nina Reiser's friends have started a Web site, www.ninareiser.com, which reminds visitors of a $15,000 reward for information leading to her whereabouts. Twenty billboards asking for help in finding her were posted throughout Oakland today.

Zografos and Nina Reiser's best friend, Ellen Doren, said they still planned to formally unveil the billboards Wednesday.

"I'm very hopeful because that's the only way to get through the day right now, to keep having hope," Doren said.

装上下巴接着说,照片中被指控谋杀的这位仁兄,Hans Reiser,可是个很火爆的牛人啊。

一般来说各操作系统都有自己的一套文件系统,所谓文件系统,就是说假如文件是一份一份由一页一页的纸组成的东东,操作系统在硬盘这个书架上如何管理和索引这些文件的。显而易见,文件系统的性能,对操作系统的表现至关重要。

早期DOS下用的是FAT,那个的确比较落后。windows后来都转用ntfs了,ntfs硬盘利用效率比较高,而且各种安全权限支持相当完善,所以比起FAT算优越多了。

Linux/Unix有一套不同的文件权限体系,linux自己用的文件系统开始就与DOS/Windows很不同,最早的是ext,到后来是ext2,ext3。现在由于Linux在各领域的广泛应用,它可支持的文件系统种类呈现爆炸式的增长。这其中不仅包括已有的windows的文件系统,另外由于服务器上linux的应用,原本只用于Unix的各种文件系统也都被移植到linux下,能在linux下得到很好的支持。补充一句,windows下现在常用的NTFS是一个例外,微软公司一直不肯公开NTFS的文档,高手们用hack的办法,能够读出NTFS的内容,但是写很容易导致NTFS系统崩溃,这是因为NTFS的权限设置方面资料不公开而这部分内容又很难hack。另外还有不少有兴趣的人,专门在linux下开发更为高效便捷的文件系统,Hans Reiser就是这样的牛人之一,而且他在这方面恐怕是这几年最成功的一个人。

Hans十年前就开始开发一种叫ReiserFS的文件系统,这个文件系统内部的管理和索引,采用了非常先进的快速平衡树查找算法(B+树算法)。在各类评测中,ReiserFS都表现非凡,尤其是在多含小文件的分区上查找和处理的效率极高。也就是说,假如你有一块硬盘,你分一个区,在上面主要不是放那种动辄数百兆上G的电影,那么你首选的文件系统,就是ReiserFS。ReiserFS近五六年里一直是Linux下最受欢迎的文件系统,因为对于日常操作,以及操作系统目录来说,最大的特点就是目录结构复杂但是小文件众多。

我03年开始用ReiserFS,很快就把我几乎所有的Linux分区都改成了ReiserFS。目前ReiserFS比较稳定的版本是3.6,其实早有人急着尝鲜用上了ReiserFS4,我比较保守,没实验过。ReiserFS4其实现在应该说工作得比较稳定了,但是一直进不了linux内核,据说原因不是技术上的,而是Hans与linux内核开发小组的关系不太融洽造成的。

现在Hans很可能会锒铛入狱,ReiserFS4估计多半会由他人转手接管,只是少了Hans这么一个天才,不知道ReiserFS今后的命运如何。其实,ReiserFS,还有现在各种文件系统开发的繁荣,都反映了一种趋势,就是很多本来只用于高端,阳春白雪的数据库管理技术,现在不断走向大众,ReiserFS应该算是牛刀小试,性能更出色的文件系统今后还是会不断涌现的。
