College English Test 4 for China: Word List 大学英语考试四级单词列表下载

This test list was developed for my niece in China, to help her prepare for her upcoming university English Exam, called the CET-4, or College English Test 4, National College English Teaching Syllabuses (NCETS). You can download it, and use it in a spreadsheet program in order to test students.

这个单词列表是给我的外甥女帮助她学习她的大学英语考试四级在中国。 你可以下载和扩大它。 它是个电子表格。 这个单词列表有3,591单子你可以学。原来这个单词列表是4个叶，我放在一起了。 你可以随机化，所以每一次你学习，你的表是不同的。过长时间你肯定都学。

我搜不了个大学英语考试标准的标准的单测列表，不知道要是这个标完全。 重复法的和宗教的已经删除了。

加油，好好学习英文！

Spanner Slotted Screw Head: Hard to Remove and Unnecessary

These spanner slotted screw heads are a pain in the butt. My broken Black and Decker VS200 Heat Sealer used 2 of 9 screws as spanner slotted, the rest were philips. Why go non-standard? photo by Don Tai

Heat sealing some frozen corn with my Black and Decker VS200 heat sealer, from a 2 kg bag down to 0.5kg bags, I heard a pop, and then noticed the heat strip of my heat sealer was no longer hot. Damn, we are going to need a repair.

as51430.net Content Spammer: Research, Ban

as51430.net spammed me, so here is the research for tracking and banning. as51430.net is out of Luxembourg. I did not get spammed by its three sister host names, lux-net-ip.as51430.net, nld-net-ip.as51430.net, and swe-net-ip.as51430.net.

Observation:
lu-customer-ip.as51430.net found the following IPs:

91.214.44.48
91.214.45.104
91.214.46.167
79.142.78.169

Research:
Further research found the following host names that change often: lux-net-ip.as51430.net, nld-net-ip.as51430.net, and swe-net-ip.as51430.net. Maybe they stand for Luxembourg, Netherlands, Sweden? Here is the complete list by ip address, so you can ban all three.

Dell Inspiron Mini 1M10V 1011: Memory Upgrade

Dell Inspiron Mini IM10v 1011, memory upgrade to 2G really made the difference. Processes are runnig much faster now.

Dell Inspiron Mini IM10v 1011, memory upgrade to 2G really made the difference. Processes are runnig much faster now.

My Aunt gave me this tiny 10″ mini laptop, running Win XP, that simply would not even boot up properly. I spent the time to clean it up, and it cleaned up pretty good. Still it was running very slow, even after killing off many unneeded processes, so I decided to upgrade the RAM from 1G to 2G. It really makes the laptop bearable, if not snappy.

udm.net: Research, Ban

a228.sub72.net78.udm.net passed me a porn referrer address. I do not tolerate referrer spam on my site, so I looked them up.

Observation:
a228.sub72.net78.udm.net 78.85.72.228

Pattern:
Fourth, 85, third, then first octet from the host name. It is essentially a reversed ip, except they omit the second octet, the 85.

Research:

t4vps.eu Content Spammer: Research, Ban

22110.s.t4vps.eu spammed me. Though they resolved a host name to 194.135.93.53, there was scant info on this host name, so I researched them. I do not see a pattern.

Observation:

bezeqint.net Content Spammer: Research, Ban

bezeqint.net content spammed me, so naturally I researched them. They are very smart, these Israelis, and employ a variety of anti-bot software techniques, in order to evade identification. Hats off to them for deploying these tactics. I hope they keep up the good work.

Observation:
bzq-80-17-106.red.bezeqint.net 82.80.17.106

Pattern:
This ISP employs 3 patterns, inter-dispersed within their Ip ranges. You need to differentiate between these three or you will ban the incorrect IP range.

  1. red: reverse first 3 octets, add 4th
  2. red, static.dcenter: straight 4 octets
  3. cablep, red: host name has 3 octets, special number for first octet

Research:
bzq-112-168-31-210.red.bezeqint.net 31.168.112.210
bzq-137-168-31-233.red.bezeqint.net 31.168.137.233

reverse.completel.fr: Research, Ban

reverse.completel.fr gave me some error 404s, so I thought to look them up. This research excludes reverse.completel.net. Be careful here because though you could ban the whole /16 range you would exclude a whole bunch of French people, and that would be bad.
