The Chaos of 4K

As a recent recipient of a 4K monitor I have taken sudden in-depth interest in the subject of 4K, or Ultra HD (UHD) to give it its other name. What I found was a confusing mix of terminology and technology.

The Standards

First off, there are two standards that are referred to as 4K.

  • UHD is 3840 x 2160 pixels
  • 4K is 4096 x 2160 pixels

The most common use of 4K as a term is for UHD, which is exactly twice the resolution of HD (1080p) as marketed in TVs, hence the Ultra HD name.

The Digital Cinema Initiatives established the 4K standard for movie projectors, exactly double their previous 2K standard.

By rights, UHD is not 4K (it’s not 4,000 pixels wide), but is commonly referred to as such by manufacturers and retailers. Continue reading…

Hosting a Site on Rackspace Cloud Files

This is part of my series of try some alternative hosting options. This time I opted for one of the less common cloud providers: Rackspace.

Cloud Files is their equivalent of Amazon’s S3. It’s designed to store files (as the name suggests), but can also be used to host static sites. It can also serve them via a CDN.

Getting Started

There was a suggestion that developer accounts got some free credit, but I couldn’t see how to sign up for one of those.

The sign-up process is simple enough, a couple of forms. You do need to enter a valid payment method. Then you’re into your control panel and away you go.

That was when I found that, if I wanted to host my files in Europe, I needed to sign up for a separate UK cloud account (like that makes sense). I thought at least it was going to jump me through the account creation process as I reached the ‘activate my account’ page, but no. Cancelling my original account was simple enough.

I basically followed the instructions in this FAQ to get it set up. Creating the container was easy and it even has an option for ‘static website.’ Uploading the files was nice via the UI, but then I found it wouldn’t load directories, I would need to create those manually.

There wasn’t a nice simple way to do this, I had to try and find a third-party script to make use of the API or use something like Cloudfuse to mount the remote storage. Continue reading…

Running a 4k screen using a Radeon HD 5450

I was the lucky recipient of a 4K monitor recently (an ASUS MX27UQ). So the question of how to drive it arose.

In order to run it at its full resolution of 3840×2160, with a 60Hz refresh rate, I assumed I was going to need a new graphics card, so started looking around. I wanted something fairly low powered (I only have a 150W power supply), silent and less than £50.

It quickly became apparent that I would need a DisplayPort 1.2 card, which supports that resolution. The most common HDMI standard at the moment is 1.4, which only supports 3840×2160 at 30Hz. There are very few HDMI 2.0 cards available (which supports 60Hz), and they’re all very expensive.

I wasn’t looking to do any gaming, so didn’t need anything very powerful. I was looking for cheap and quiet. That combination proved elusive though, with most cards either having a fan, not enough resolution, being quite expensive or no longer available.

I was leaning towards a new motherboard as the cheapest option. This MSI board seems to have all the right specs and I almost bought that, except I realised it’s the CPU that’s responsible for the graphics and my G3258, which doesn’t even have a version on its Intel HD graphics, wasn’t going to cut it. I’d need to buy an i3 chip at least, which made the whole bundle way more expensive than a graphics card alone. Continue reading…

Hosting a Site on Google Cloud Storage

This is part of my series of try some alternative hosting options. Next up, I decided to try Google Cloud Storage. Amazon’s cloud platform is probably the best known, but it’s far from the only one, with plenty of competitors, including Google.

Cloud Storage is their equivalent of Amazon’s S3. It’s designed to store files (and there are options about how fast it retrieves them), but can also be used to host static sites.

Getting Started

There’s a free trial, with $300 of credit to use (although it expires after 60 days) which is simple enough to sign up for. The one irksome thing is that it requires you to register a payment method.

I happened to sign up with a Google Apps account and found I was unable to create a project (seemingly required) until the administrator (thankfully me) had enabled the Google Developers Console app. Something to be aware of.

I switched around Google’s official instructions, partly because I had already read these, and partly because it was obvious I wanted to set my site up before I moved my DNS.

You then need to create a Cloud Storage Bucket, with the name of your domain as the bucket name. To do this you first need to verify you own it. You have to do this through Webmaster Tools, which was another app I needed to turn on in my Google Apps console.

Most of Google’s instructions involve using their command line gsutil application, but can also be achieved through the web UI. Continue reading…

Hosting a Site on NearlyFreeSpeech.NET

This is part of my series of try some alternative hosting options. Next up, I decided to try NearlyFreeSpeech.NET. It’s a long-standing pay-for-use service that’s been around since 2002, so has a good history and isn’t about to disappear.

Getting Started

The setup process wasn’t particularly straightforward. First, you need to create a member account. Then a billing account (you can create multiple of these), then a site (again, multiple supported). Note that you have to enter a bunch of name and address details in your account record. You should get a couple of cents to allow a ‘trial’ when you create it.

To run it permanently, you’ll need to deposit some funds. What it costs to run is based on the type of site(s) you set up, as it’s essentially a combination of bandwidth, storage space and ‘Oomph!’ — or CPU+RAM.

When setting up a site, you get the option to pick from the different types of site. Static sites don’t incur a daily base charge ($0.01 for dynamic sites) or a cost for resources (based on a unit of CPU+RAM called a RAU).

Bandwidth starts at $0.25 per GB, but it goes down depending on how longer you have been a member and how much total bandwidth your account has used. Their pricing estimator put me at about $0.50 a month.

As part of the setup process you get an alias — essentially short_name.nfshost.com — this is what you need to create a CNAME for if you host your domain name elsewhere. In order for NFS.NET to associate your domain with your account you need to add the domain name as an alias of the site.

They don’t seem to advocate using a bare domain (leepenney.com) but rather the www subdomain (www.leepenney.com). As most of my static site was setup for the bare version (references to CSS files, etc) I had to add an additional alias to cover this. Continue reading…
