I will definitely need this very soon for my home security cameras

Quick link - Another Hosted server solution
Am saving this link on my blog so i can refer to it later when am looking for a hosted server solution.
Servers and Virtualization
Hardware you trust: your VPS servers will be located on trustedSupermicro servers with Intel Xeon CPUs, ECC RAM and Intel SSD drive arrays. Servers are never overprovisioned, meaning you will have enough power to run your applications any time.
With OpenVZ container virtualization we make sure your VPS RAM won't be spent for running Linux kernel or system drivers. All of the memory will be available for your applications and software.

My Android Phone Keeps loosing the network connection
Problem:
My android device keeps loosing network connection and every time i have to reboot it or manually search for network operator before it can reconnect again.
Solved:
Lock the phone to 2G only.
This bug is common with network operators who have both 2G and 3G networks operational.
if you phone is set to "Auto" latch onto 2G/3G, it will tend to loose the network sometimes.
You will realize that if you transfer the SIM card to a 2G only phone, the situation will be normal.
once i realized that, i decided to set my phone "network mode" to 2G only and it has been stable ever since:

Tracking routed vlan interface statistics and bandwidth shaping on Juniper switches - ex4500 series
I have just finished provisioning two different internet customers (one supposed to be 4 Mbps and the other 3 Mbps up/down) on a Juniper ex-4500-40f series switch.
The next step was to do bandwidth limiting on these customers but i have hit 2 very annoying snags with this model of juniper switch.
1. The bandwidth policer can ONLY work for ingress traffic (this would be up-link from the customer) which is usually a non issue for the ISP because Uplink is little traffic compared to down-link!
For egress traffic, am supposed to do "bandwidth-shaping" but yet again it's not supported for logical interfaces! WTF Juniper!
2. The ex-4500 does NOT support tracking RVI (Routed VLAN Interface) statistics! meaning there is no way i will be able to track the throughput for my internet customers. This is really annoying because even you SNMP tool won't be able to monitor such interfaces no matter how fancy it is!

Sorry if you landed on this page because of the same issue.
Funny thing is RVI stats are supported on the lower versions ex3200 and ex4200! up to now i don't know why the F*** Juniper decided to do it like this. Ideally higher switch models should inherit all the good features from it's predecessors and even get better.
Here are two screen shots from my ex4200 and the annoying ex4500!:
On the 4200 you are able to the the ingress stats whereas on the 4500 there is 0.
I really don't know if there is any work around this "show stopper" on the ex4500! please comment if you have any break through on the 4500 regarding rvi statistics or rvi egress bandwidth limiting.
will appreciate.
