Final fix for water in canister

If your Toyota or Scion car has check-engine light on after driving in heavy rain, you may watch this videos for diagnosis (ignore the fix part):


And this video for purging water out of the canister pump module:


For the permanent fix, block the small holes under the gas-feed inlet (take off the rear tire at the driver side and look up):

Piaggio/Vespa scooter regulator test and replacement

The battery on my Piaggio LT150 is no longer charged while riding. It took me quite a while to figure out how to access the charging unit, turned out to be quite easy as showing in this video:


This video also shows how to test the regulator, replace it and mount everything back.

The best version of Yandex

17.1.2.339.  Older versions cannot block some sites' pop up ads, such as 6park.com, and no option to save passwords for many sites. Newer versions have the tableau totally messed up.

Yandex

[in Chinese]

老的版本不能阻挡一些网站的恶性弹出广告,比如6park.com,很多的网站也不提示密
码保存。新的版本呢,常去网站的标签一塌糊涂,名不相符。

我衷心感谢Yandex终于做了一个在手机和平板上真正能替代桌面电脑的浏览器。从用PDA那
时候开始,我就一直梦想这么个浏览器。我现在很少带电脑出门了,因为这下手机上都可以做了。
  • 能无极缩放,又能自动满行,还有阅读模式。
  • 能记住所有网站的密码。当然你也可以选择不记。
  • 支持所有的电脑上的Chrome和Opera的插件,也就是这个浏览器无所不能。
  • 页面整洁,不像Chrome和UCWEB里的有些字太大、有些字又太小。
  • 看Youtube没有广告(不需要安装任何插件),自动全屏。
  • 不像UCWEB和Chrome那样发热耗电。
  • 写了一半的帖,reboot后都还在,一字不漏。
  • 地址栏在下面,很贴心(平板时还是在上面)。

Two big problems with Le S3

Encountered two big issues with the Le S3:

1) No android.net.conn.CONNECTIVITY_CHANGE broadcast, apps are not aware of network changes, such as register loss of SIP after switching from WiFi to mobile data or vice versa.

2) No setExactAndAllowWhileIdle(), apps cannot do things periodically, such as register of SIP every 15 minutes.

The result is: communication-based apps become totally unreliable. Seems a general issue of such Chinese phones.

[Solution] Install the unofficial LOS 13.

 [In Chinese]

一是没有android.net.conn.CONNECTIVITY_CHANGE广播。没有这个广播,apps无法知道
网络有没有变化。自Android 5.0一来,这个广播总是乱广播、误广播,所以我在我自
己的app里对这个广播做仔细的过滤。我能理解乐视的工程师为什么要这么干,但是这
是典型的中国式的不守规矩,在美国不能也这么干的。

二是没有setExactAndAllowWhileIdle()。没有这个,apps无法定时做一些事情。比
如Sipdroid每15分钟要注册一次,就没法子了。我也能理解在流氓软件遍地的中国,为
什么乐视的工程师要这么以流氓的方式对付流氓,但是你在美国卖这个手机,就不能这
样耍流氓。

这里一位老兄也遭遇到了这些问题,他说中国的手机大多都这么干:

https://stackoverflow.com/questions/40931966/android-alarmmanager-setexactandallowwhileidle-and-wakefulbroadcastreceiver-no

需要用手机干正经事的,还是不能买这些国产手机。Axon 7我没有真正使用过,不知道
是不是也是这样,多半没有,因为中兴和华为已经在美国卖了很多年的手机了,应该没
有这么重的流氓习气。

对于不是码农的普通用户来说,结果是网络活动不牢靠,比如微信和邮件不能及时推送
到手机上,Hangouts之类的漏电话,定时的事件不会按时发生。。。好处是省电,类似
于苹果那样的流氓加恶霸式的强行关后台。

是的,我已经在电池管理里面折腾过了,没效果。

【解决办法】刷unofficial LOS 13,一切问题都没有了。

How to solve the touch issue of ZTE K88

If you experience touch issues, you must update your Trek 2 HD. It is a very tricky process though.

First thing first, you must insert an active SIM card that uses AT&T network, such as H2O or AT&T prepaid (goPhone). You don't need to enable data, you can disable it, but you should use AT&T's APN.



Now connect your tablet to Internet via WiFi. Wait for a while for the auto update to start. Once started, you can see downloading activity in the WiFi icon:



If no go, reboot.

If still no go, force update manually. Go to settings and AT&T Software Update, Check for Updates. If it goes through, all good. If not, saying "try again after 24 hours", then you need to change your phone's date one day ahead (tomorrow). Then reboot, wait for a while for it to auto update. If no go, try manually update again. If fails again, repeat.

You have to update to B29 or B33, to solve the touch problem.
