This is the best vnc viewer I have ever seen.  It's Enhanced VNC Thumbnail Viewer :

undefined symbol: ap_cache_cacheable_hdrs_out

After enabling mod_mem_cache, I encountered these errors when restarting apache:
* Restarting web server apache2
 * We failed to correctly shutdown apache, so we're now killing all running apache processes. This is almost certainly suboptimal, so please make sure your system is working as you'd expect now!
 ... waiting apache2: Syntax error on line 204 of /etc/apache2/apache2.conf: Syntax error on line 2 of /etc/apache2/mods-enabled/mem_cache.load: Cannot load /usr/lib/apache2/modules/ into server: /usr/lib/apache2/modules/ undefined symbol: ap_cache_cacheable_hdrs_out!

Just put:

LoadModule cache_module /usr/lib/apache2/modules/


# Include module configuration:



And it's fixed!

Google products often choose Thai interface for me and this is the real problem

Can I call it a "bug"?  This is far too annoying.  Yes, I am THAI and my English is not that good BUT the Thai interface SUCKS.  I should have right to choose which Language I prefer.  There is no obvious place where I can set it.  Some products have, some don't.

Fortunately, people find a way to change the interface language by appending these 2 HTTP GET variables depending on the URL you are seeing:


Note that it will only work with your current session.  If you come back later, you may need to do it again.  You should have a real fix for this, Google.

mosh - mobile shell with roaming and intelligent local echo

mosh  (mobile  shell)  is  a remote terminal application that supports intermittent
       connectivity, allows roaming, and provides speculative local echo and line  editing
       of user keystrokes.

       Compared  with ssh, mosh is more robust — its connections stay up across sleeps and
       changes in the client's IP address — and more responsive, because the  protocol  is
       tolerant  of packet loss and the client can echo most keystrokes immediately, with‐
       out waiting for a network round-trip.

zyxel wap 3205 - number of wireless clients limitation

Zyxel WAP 3205 can work in "wireless access point" mode.

When its firmware was version: V1.00(BFR.2), it could accept only 15 wireless clients.  But after I have upgraded its firmware to be version: 1.00(BFR.6)C0, I can now see 27 wireless clients.  It could be more.  I just don't have more computers to test.
