7Timer! starts service operation since Nov. 9

Published at 23:25. Filed under English version; no comment so far.

The trial period lasts more than three months, mostly because my lazyness ;-) Okay, tomorrow it will ends, the service operation will begins since Nov. 9, as Obama's election word, "change", ehehehe. However, this change will not affect most things at all, it just show that things are stable enough for you to use.

I simply do a few enhancements of the website before annoucing this. There are a few new products on the schedule list, e.g. APanel Smart and Weatherman, etc. But however the most urgent thing for me is the GRE/AW exam on December. So development is terminated now -- unless anyone with a good English would like to take the exam for me.

Happy using to all!

关于SYSURNS在11月7日预报事故的说明

Published at 0:18. Filed under 中文版日志; 1 Comment

  11月7日傍晚,在一道锋面的影响下,中大在广州的3个校区先后出现了短时强降水,这也是对SYSURNS在11月6日开始运行以后的第一次考验。

  SYSURNS的数据源—— HKO/SWIRLS较准确地预测到了锋面的到来,尽管19时前后在广州市区西南方出现了小规模的对流爆发,使得SWIRLS的预测并不是完全准确。

  作为SYSURNS的首次考验,敝人自下午16时左右即开始透过雷达影像监测锋面动态(向朋友发送的提示短信则在上午10时左右发出)。大约18:40左右,敝人留意到SYSURNS工作异常,对锋面雨带反应失灵,遂投入检修工作,至20:20左右故障排除,SYSURNS在约20:45恢复正常运行。经检查发现,此次事故系数据处理检索命令发生错误所致,这一错误导致返回的数据并非指定地点的数据。

  敝人就这一事故对各位造成的不便表示歉意,并将努力减少故障的发生率。

7Timer! core dumps around Nov. 2

Published at 23:48. Filed under English version; no comment so far.

I should write about this earlier, but I just got too busy and forgot about this issue until today. Okay, at least it's not too late now.

The server encounted a problem while runnning a Weachart test, and the disk was filled with around 150,000 fragments from the failure. I work two days to remove them all and the service was back to normal on late Sunday.

In the Sunday morning there is another failure of the server by a reason which still unknown, but it was fixed in 4 hours.

So now the two services -- APanel and Weachart are both in normal run. I'll do some clean up this weekend to remove the "test" text on the first page.

Thank you for you all,

Quanzhi
