    Gigabyte Z97X-UD3H and M.2 SM951 link width

    Just built myself a new gaming pc/hackintosh and just curious about the link speed of my M.2 drive, as currently it only connects at x2 which gives me around 750MB/s read/write. Understand this drive is capable of quite a bit more! * Gigabyte Z97X-UD3H * i7-4790K * 4x 8GB Corsair Vengeance *...

    Toshiba Canvio Basic 2TB External 2.5" (HDTB320EK3CA)

    Slightly odd request... does anyone know what the internal drive is inside this enclosure? I want to put the 2TB drive into a small ITX build and then put my spare 500GB drive into this enclosure but I'm concerned that internally they might use some proprietary connector like my 2.5" WD...

    Thunderbolt 4K bandwidth and 10GbE

    I'm currently using my old iMac 2011 with a i7 chip, it's fairly quick but my MBP Retina 2014 is lightning fast in comparison (I do quite a bit of CPU intensive work and works out about 60% faster). With this in mind I'm considering buying 2x 4K monitors for use with my MBPr then use this as...

    Always check trim is enabled on aftermarket SSD drives!

    Just checking up on my SSD today and was a little shocked it was this bad! When I first installed Yosemite I enabled trim and double checked it was enabled but another update must have disabled it again. Just a heads up to others out there with aftermarket SSDs to check it's enabled :)

    Modify HTTP traffic on the fly

    Slightly strange request, I have a Sonos system and want to intercept and modify the HTTP API traffic. So volume control done via the Sonos app will control my amp via IP (I understand that the normal way is to just turn the amp volume quite high and manage the volume via Sonos, but this is [H]...

    Supermicro X9SRL IPMI

    Been on the look out for a good server motherboard deal for some time now and got too excited when one popped up I didn't read the model number correctly. I have bought an X9SRL (without -F) and it doesn't come with IPMI, is it possible to add it via some sort of add in card? Probably a...

    OS X 10.10 broken animations/UI interactivity

    Bit of an odd one this which I can't quite figure out. Basically after a few hours use my 2011 iMac running Yosemite 10.10.1 will stop all it's pretty UI interactivity, by this I mean: The dock no longer magnifies when I hover over it Clicking a link in the browser does not show the clicked...

    Areca 1882ix-8 "Waiting for F/W to become ready"

    Been having a few issues the past couple of weeks where when powering up my file server, it gets stuck on the "Waiting for F/W to become ready" boot screen. Then ends up rebooting every 300 seconds in a endless loop. The server isn't powered on 24/7 due to the insane amount of power it draws...

    Apple wireless keyboards

    I just bought myself a new retina MBP and noticed the keys are a much lower profile than my previous MBP and wireless keyboard included with my 2011 iMac. Are the newer wireless keyboards the same low profile as the rMBP? Got to say I much prefer the lower profile! Just wondering if...

    Quieter HDD cooling in 24 bay case

    I currently have an Xcase RM 424S (similar to the Norco product), which is a 4U 24 bay server case, with 17 HDDs. My motherboard is an Supermicro X9SCM which from what I gather only offers speed control of PWM fans. The case...

    ZFS Mixed drive sizes in a single pool

    Mac to Mac networking with Thunderbolt

    Sudo password-less commands

    I am trying to create a PHP script which will SSH into my NAS and power it down. Probably better ways of doing it, but thought this would be the easiest. PHP side I am fine with, the issue is creating a sudo command which can be run without a password. I have created a user 'power' with...

    Myricom 10GbE performance on OS X 10.8

    I have a small 10GbE network at home (used for work) consisting of a NAS and a bunch of ESXi hosts. I recently decided to take the plunge and spend far too much money getting my iMac (i5 / 16GB DDR3 / SSD) onto this network using a Sonnet Echo Express thunderbolt enclosure, Myricom...

    Dell PowerConnect 8024F and 5524 for 10GbE

    I am currently learning various networking techniques, setups etc all in my personal time. So please bear with any things I have overlooked here. This is a huge learning curve for me. I have been offered a 8024F SFP+ 10GbE switch and found a 5524 fairly cheap on eBay (A tad over £1k for both...

    Running mySQL database from memory

    I have a PHP based app service which allows a load of tablets on a LAN to communicate with each other. Everything is stored in mySQL with around 100 queries a second :eek: The database never exceeds 50MB in size. The app only runs for 4 hours. It's a pile a crap, there is no budget for a...

    mySQL returning multiple rows from other tables

    Overwrite default keyboard volume controls when external device connected

    Just had a mad idea, I connect my iMac to my amp through TOSLINK and the only way to control my amp is via IR (or get off my bum to use the volume control :rolleyes:) Is there a way in which I could overwrite the standard functions of these buttons (ideally only when an external device is...
