Linode upgrades hardware and 2X RAM increase coming soon

Linode is my favorite go to provider for virtual private servers. I have been using Linode in production for more than 2 years and I have yet to face any trouble such as down times etc. You can find the reviews I done here and here . I know linode is expensive but their service is purely unmatched by its rivals. Linode has perfected the VPS industry. Their control panel is simply awesome and its still wondering how they pull of things like Ram,HDD bumps every year or so by only requiring a simple reboot of the VPS that you are using. They have 6 data centers around the world and they have hardware uniformity on all data centers.

Last week Linode announced a series of upgrades to its service by giving us 10X bandwidth upgrade. You can see the official announcement here. They have completely overhauled their network architecture by using redundant Cisco Nexus series routers. And they have done that without even clients knowing it. No downtime or packet loss during the upgrade. I know they can pull this kind of stunts thanks to their servers having dual NIC’s but still its amazing how they upgraded thousands of hosts on 6 data centers without even causing a blip.

Yes you can. hacker community is blown up today thanks to a Australian hacker who found out a very easy way to do that. Engineering and manufacturing any kind of processor is really expensive and hardware vendors like to keep the costs down by making one model and then striping down the abilities of it and making different versions by using the same model.

Simcity launch turns in to a disaster thanks to DRM

Leave a reply

EA launched Simcity last Tuesday and its been a mess until now. See the screenshot above, everyone is complaining that they cant play the game due to server problems on EA’s side. Days have passed and biggest game company on the world still cant figure out a way to fix the problems. 24 hours is acceptable, 48 hours? Okay! But now 5 days have passed and still there is no fix. As a result of that Amazon now stopped selling the game and started refunding the refugees.
SimCity requires the players to be online all the time as a DRM ( Digital Rights Management ) solution, because then they can iron out the game pirates from using cracked versions of SimCity. While this sounds good for EA it can be really annoying for the players because of many reasons
