来自主题: Programming版 - 各位所在公司的code review烦人不?
我们传的 1024 左右 bytes 的 message,也不小了,
我住过的美国 Apartments, 设置 Xbox 测试 MTU/MSS 的结果一般是 1500/1460 bytes,
比 1024稍大。但是如果你Google MSS, 也有说不少是 500 bytes 左右的 MSS.
对于传给 TCP socket 的 message,只要 TCP 自己做了分包分出了更小的 TCP
segments,
然后这些 segments 在中间网络经历的延迟不一样,
socket receiver 方一个 recv() call 就容易收不到完整 message.
当然还有其他原因,也会导致receiver方一个 recv() call 收不到完整 message.

来自主题: Programming版 - 各位所在公司的code review烦人不?
你这个实际情况还真不容易碰到收不全的。
因为你的 1024 小于一般以太网的最大包的大小,
就是你测的 1500。中间的路由器没有神魔事情不
会乱切你的包的。到接受方的 OS 也不会去没事
去切分你的包。相反,OS 缺省配置会合并你的包,
不会每个 packet 都返回给用户的,这样系统调用
的次数太多。所以一般跑起来都没有事。
我的猜想是你要是 1024 大小,每次来回应对,
实际测跑出个不完整的接受很困难。
当然程序还是不应该有这个 bug。

来自主题: Programming版 - feof always return true
why?
I am reading a binary file from a sftp resource.
while (!feof($file)) {
$content = fread($file, 1024 * 10);
$bytes_read = strlen($content);
if($bytes_read == 0) break;
print_r("read bytes: ".$bytes_read."n");
fwrite($newfile, $content, 1024 * 10);
}
if I leave out the $bytes_read, it becomes an infinite loop.

来自主题: Programming版 - MongoDB快超过Postgres了
没太懂这个的意思,我看文档说的是,被index的key value不能超过1k大小吧
http://docs.mongodb.org/manual/reference/limits/
Index Key
The total size of an indexed value must be less than 1024 bytes. MongoDB
will not add that value to an index if it is longer than 1024 bytes.
你说的好像是一个 index 的总长度不能超过1k? 你到底说的是“被index的key value
”还是“一个index总长度”?
index的key value大小不超过1k,看着是比较合理的限制呀。

Just got a SGI 1600SW display for my O2. However, The
display resolution
is still 1280*1024 and the display is just scaled to fit the
wide screen.
There is no 1600*1024 option in the Display Properity
control panel.
How can add such an option?
Thanks a lot. This is really a nice LCD.

although I have not tried that, but theoretically there
should be little problem.
You will have to use a port above 1024 as the ftpd listening
port, as listening
on a port below 1024 requires root privilige. Still you'd
better set the root of
your ftpd to a sub directory of the user account home
directory, so that the ftpd
could manage its own passwd file.

I have a problem question when I try to install
unix7.1. I have a ME in my computer so I left
2G to unix, but cylinder number is larger than
1024, so there is a error when I add a unix native
partation. I don't want to resize my dos-partation
Could some friends tell me how to resolve it in such
case? (mean how to install it when boot partation larger
than 1024)? Thanks a lot!!

来自主题: Unix版 - Question on file descriptor
We want to change the limit of file descriptor to 1024, so we did:
"limit descriptors 1024"
But looks like it is session-dependent, which means if we close the log-in
session and open a new session this value is restored to the previous one.
My question is how to make it system-level?
Thanks in advance!

标题: 广西边境与越南的通婚现象有多严重
发信站: BBS未名空间站(Fri Oct 20 13:20:07 2017,GMT)
广西边境与越南通婚现象是比较普遍的。本人由于工作原因,经常到龙州、凭祥、东兴
等边境出差,虽然见到真正结婚的不多,但听说的倒是不少。
为什么广西边境和越南通婚比较普遍,相比于其他边境身份例如云南、黑龙江等。
广西和越南有1024公里山水接壤。很多广西的村庄和云南的村庄是紧挨着的。在这1024
公里接壤的地方,有30几个边民贸易互市交易点,中越两国之间的贸易还是很频繁,边
境贸易人民的来往很密切。
广西边境和越南边境两国人民的生活习惯较为相同。虽然是两个多家,但都生活在彼此
的附近,喝的水都是一样,讲的方言都是一样,全程交流无障碍,这也是广西边境和越
南人通婚的重要原因。越南边境和广西边境人民生活习惯较为相同。再者广西和越南边
境没划分那么清的的时候,很多人都不知道自己生活在越南还是中国。
广西边境娶不到老婆,给不起聘礼的实在是不少。广西边境有贸易的地方,边民的日子
比较好过,有边境贸易政... 阅读全帖
