• Android Performance Question : Many small apps or one big app?

  - by kunjaan

  I read this quote in one of the webpages: If you are writing a large application, consider dividing it into a suite of applications and services. Smaller applications load faster and use fewer resources. Making a suite of applications, content providers, and services makes your code more open to incorporation into other applications as described the "Use and be used" tip. Is this true? What is the thumb rule for the size of app?

• How can one send commands to the "inner" ssh session?

  - by iconoclast

  Picture a scenario where I'm logged into a server (which we'll call "Wallace") from my local machine, and from there I ssh into another server (which we'll call "Gromit"): laptop ---ssh---> Wallace ---ssh---> Gromit Then the ssh session from Wallace to Gromit hangs, and I want to kill it. If I enter ~. to kill ssh, it kills the ssh session from my laptop to Wallace, because the ~ is intercepted by that ssh session, and the . is taken as a command to kill the session. How do I send a command to the ssh session between Wallace and Gromit? How do I kill my "inner" ssh?

• Wireless very slow on one laptop on network, all other machines normal?

  - by th3dude19

  My new laptop (Acer Aspire Timeine 3810TZ running Windows 7 Home Premium 64bit) is acting very strange on my wireless network. Below are the issues I'm noticing... The connection frequently drops. I see the icon change from 'full bars' to 'empty bars with yellow star (meaning no connection)' occasionally. Almost every website I visit (Firefox) hangs for a long time on 'Looking up www.amazon.com' for example. After a long pause, it finally starts loading the website. Neither of these problems exist on any other machines on my network. I also have a desktop running the same OS wirelessly and it works fine. I've run several Speedtest.net tests and the speeds are great (20MBit down/4 up). Results from pingtest.net are as follows: Line quality: D Ping: 46ms Jitter: 65ms Packet Loss: 9% These results are to a server that is less than 10 miles from my residence. The results on the other machines in my house are normal. Any suggestions? This is becoming very annoying as I purchased this machine primarily for browsing.

• How could one track all emails sent from employees?

  - by Schnapple

  My client runs a small business. This business has a small number of employees. For various reasons, my client would like to be able to have a copy of all of the emails sent from their employees BCC'd to them. The net effect here would be similar to the access they would have if they hosted their email through Exchange but the business is too small to make this a feasible option. They are currently hosted through GoDaddy. I have not investigated it myself personally but apparently GoDaddy can do something along these lines for all incoming email but not for outgoing email. Is there a way to set up email accounts for a particular domain to where a specified admin user could be copied on all outgoing email? UPDATE: I've modified the title to reflect that it's employees not just users who are the goal here. Also I forgot to mention how they currently do email through GoDaddy - POP3. I think maybe IMAP is also possible through GoDaddy, not sure. And yes, the bottom line here is to basically emulate a feature of a larger-class platform through a smaller, cheaper platform. Opinion-only answers should probably be relegated to the comments. For the sake of argument let's say that any legal requirements have been met.

• How can I switch from a custom linux network namespace back to the default one?

  - by Martin

  With ip netns exec you can execute a command in a custom network namespace - but is there also a way to execute a command in the default namespace? For example, after executing these two commands: sudo ip netns add test_ns sudo ip netns exec test_ns bash How can the newly created bash execute programs in the default network namespace? There is no ip netns exec default or anything similar as far as I've found. My scenario is: I want to run a SSH server in a separate network namespace (to keep the rest of the system unaware of the network connection, as the system is used for network testing), but want to be able to execute programs in the default network namespace via the SSH connection. What I've found out so far: Created network namespaces are listed as files under /var/run/netns (but there is no file for the default namespace) The ip netns exec code can be found here: http://git.kernel.org/cgit/linux/kernel/git/shemminger/iproute2.git/tree/ip/ipnetns.c#n132 - I haven't grasped everything that it is doing yet, but it doesn't look very promising. ip netns identify $$ as suggested by Howto query and change network namespace on linux? returns nothing when in the default network namespace

• I want Lotus Domino to only send one email to users that are both recipients and members of a cc'ed lotus group.

  - by Marcus

  Lotus Domino 7 and now Lotus Domino 8.5 The scenario: A@mycompany writes an email to b@internet and cc's it to group@mycompany. A@mycompany is a member of group@mycompany. With the initial email Domino is intelligent enough to not send the email which a@mycompany just wrote to a@mycompany again. But when b@internet answers to all (a@mycompany + group@mycompany) then a@mycompany gets this email twice, because he is not only the author but also a member of group@mycompany. During the smtp session the email is sent once with the recipients set to a@mycompany and group@mycompany and a single esmtp id. So Domino should well be able to see that the mail should only be sent to a@mycompany once. Can I make Lotus Domino behave in this sane fashion?
