Macbook Pro 15″ (2011) USB Port Issue

I had an alarming issue where one of my USB ports (the one closest to the display) wasn’t recognising any devices… It would charge them up without any problems, but things like USB hard drives and iPhones would not mount. I thought that this was a hardware fault, and was preparing myself book a slot at the Genius Bar.

However, by resetting my PRAM and NVRAM, I managed to fix the problem. To do this, first power off your Macbook Pro. Then, hold down the option key (alt key), Command Key, P and R simultaneously. While holding these keys down, press the power button once and wait for the computer to chime. Once your laptop has “chimed”, it will restart – you can then release the keys. Your NVRAM and PRAM will now be reset – and hopefully, your USB Socket will resume normal operation!

I hope that this helps!

 

Dedicated Servers

I recently bought a Kimsufi-2G Dedicated Server from OVH (well, Kimsufi…). I’m using it to host project websites, where non-php programs might need to be run. Infact – I moved this blog over to the new server, so if you’re reading this, then all is well.

I’ve always wanted a dedicated server. VPS’s are good, but the thought of having a physical machine in a datacenter somewhere is, for some reason, very appealing to me. The server is costing me £16.80 a month, which isn’t too bad. I have  5TB of Bandwidth, 1TB hard disk, 2GB RAM and 1.2GHz Celeron. At first, I thought that the processor would be horrifically under-powered for my needs – but it’s coping very well. Infact, it’s doing better than another server I had, with a 2.66GHz Celeron Processor. The 1.2GHz Celeron is considerably newer than the 2.66GHz Celeron, and has 512KB L2 cache rather than 256KB – I put the different in speed down to that.

I opted to install Virtualmin, so that if any of my friends needed some hosting, I could quickly create them account. It uses a bit of RAM.. at the moment, with a couple of dynamic sites (including this one), memory usage is at 384MB. If this where a low end VPS, i would be slightly concerened – but given that I have 2GB RAM, it’s not a big issue for me.

I have set up the dedicated server to be my primary nameserver, with my $3.50/m BuyVM VPS being my secondary. This should provide a decent amount of redundancy, as the two servers are physically very far apart.

It is very tempting to get a Kimsufi 16G, which would have (as the name suggests) 16GB RAM, along with a quad core I5 (or better), a 2TB Hard Drive and 10TB Bandwidth for £43/m. However, I can’t really justify that price… especially since my £16.80 Server is treating me just fine.
