Google to merge Android and Chrome OS as an all in one operating system (or are they?)

So Google have finally taken the leap. They are going to merge Android and Chrome OS.

The Wall Street Journal report that Google have announced a formal move, with the Android OS expected to be tweaked and take over Chrome OS rather than the other way around. It seems the plan is to launch the new OS in early 2017, and we can no doubt expect development builds to appear before that.

Just what this will mean for current users of both systems is unclear, but Chromebooks will no longer be Chromebooks, although the OS is apparently to be opened out to hardware makers so that they can continue to utilise it. The Chromebook OS doesn’t have the same appeal as Android with a lack of apps and a user base which is hardly troubling Microsoft. Android on the other hand isn’t very useful when presented with a keyboard or mouse. The big trick Google will have to pull off is a seamless interaction between all types of devices whereby the user experience remains the same whether on a 3” smart phone screen, or on a 50” IPS display.

This should be a good move for Google. An already massive Android user base which knows what to expect will be hungry for a light replacement to Windows and it’s forced updates (see the previous article). If they can manage to come up with a system that keeps the simplistic usability of Android with the functionality of a full OS working on a desktop, then they might just start a revolution.

No doubt we’ll have more announcements soon from hardware manufacturers, and it will be interesting to see what the web community makes of it all.

Edit: 03/11/2015 – So it appears that Google are now saying Chrome will not be killed off as an OS. A post on the Chrome blog has categorically denied any intention to get rid of the system, saying it is staying and will remain supported for the foreseeable future. It seems the Wall Street Journal may have got the wrong end of the stick from a development post which discussed amending Android to work on laptop form factor. So if you own a Chromebook, then stop panicking, It isn’t going anywhere!

Thinking inside the box – Just what are the bits inside your PC?

If you want to build a PC, then you need to understand the bits needed to put it together. The basics are:

    • A case. This can be a full size tower, or mini-ATX, or even small form factor (SFF). The case size is important, as the interior volume will dictate how many components you can fit inside. Which one you need to choose is going to be dependent on what you want the machine to do and therefore what components you will add to it. Buy an SFF and find that in a year’s time that you buy a game that needs extra RAM to run, but you don’t have any spare sockets then you are going to have a problem!
    • A power supply. This needs to be powerful enough to provide usable power to all of the other components you decide to use. It is always a good idea to provide some headroom in your calculations, as you may want to upgrade or add further components later (unlikely to happen if you go down the mini-ATX or SFF route).
    • A motherboard (MOBO). This is the circuit board which will allow you to plug in everything else to make it work. There are many manufacturers who will generally produce a wide range of boards, each with particular characteristics, and each will be designed for one particular brand of CPU (AMD or Intel). Which one you choose will be a matter of personal preference rather than a particular need, as for the most part, the CPU’s will do largely the same thing. It is only when you need a very specific task carried out that you would need to consider the intricate variances between manufacturer architectural design.
    • A Central Processing Unit (CPU). This is the brains of the operation. The CPU carries out the task of processing all of that code so that you can make the mouse move room one side of the screen to the other. Of course that is an extremely narrow view of what this component does. These days they are multi-core, multi-threading beasts which make sure that everything that you need done, gets done. There are two main manufacturers. AMD and Intel. The CPUs they produce are made using slightly different processes and designs to achieve broadly the same tasks. They are not however interchangeable. You cannot use an Intel CPU on a mobo designed for AMD processors, and likewise AMD will not fit an Intel based mobo. These differences are known as socket variants, and are something you need to understand (at least that the difference exists!) if you want to build your own machine.
    • Random Access Memory (RAM). This is what allows the machine to carry out the processing it needs to do. The CPU will actually crunch the numbers, but to do so it needs to utilise information stored elsewhere (see HDD below). This is where RAM comes in. This is a silicon chip which acts as a file retrieval system for the processor. It gathers and stores the information needed by the CPU, and is used as the processing speeds are so enormously fast that direct reading / writing to and from the HDD by the CPU would be impossible. RAM is volatile memory, so once the machine is powered down, the RAM no longer stores any information. It’s purpose is to facilitate getting information between the HDD and the CPU.
    • Hard Disk Drive (HDD). The HDD is where everything is stored. When you save a photo, or run a program (or app) the HDD is where the information comes from. The CPU takes the information, processes it, and displays it via the GPU (see below). There are different types of HDD. The most recent incarnation is the Solid State Drive (SSD). This utilises chips similar to RAM to store information. The benefits are the small physical size of the drive, and the fact that there are no moving parts to break down. High cost per Gb of storage is the main downside of using SSD. The most popular type of drive in use is the mechanical drive. This consists of a number of magnetic platters which spin inside a housing. While the cost per Gb is lower than SSD, they are noisier and produce more heat (thereby using more power). There also hybrid drives called SSHD. These are a mechanical drive with a small SSD included. The SSD portion is used to store the most accessed programs.
    • Graphics processing unit (GPU). The GPU is used to display the GUI (graphical user interface) which is simply how a program looks on the screen. For most programs, this is a fairly basic static screen, with not a lot of moving pixels. The amount of processing to be carried out by the GPU is therefore quite small. Most decent motherboards will have a small built in GPU, which can handle most basic applications. They will even allow casual gamers to play without any noticeable depreciation in user experience. If however you are editing video files, or playing graphics intensive games then you need more processing power. For these instances, you will want to add a dedicated graphics card. For lower end cards, expect to pay up to GBP50, for mid range up to GBP150 and higher end cards can be anything at all. Some have been on sale recently for GBP4000 or more. If you need one of those cards, chances are you’ll already know all of this though!

    • Other items you may wish to add. There are all manner of additional things you can get. Card readers, DVD / Blu-Ray drives, information panels, sound cards (like a GPU, but processes audio rather than video). Any of these (or indeed other items) would be a matter of personal preference rather than necessity.

If you do decide to go down this route, then you need to plan carefully. You need to ensure that the mobo and CPU you choose are compatible. The RAM needs to be consistent with the clock speeds offered by the mobo. How much RAM will you need? That will of course be dependent on the tasks you expect to do. That should always be your starting point. What is it that I want this PC to do? Once you know the answer to that question, you can then research just what specification you actually need.

PC Hardware modding – why do some people feel the need?

PC gamers have always sought to have the best equipment so that they can play the latest games. This, of course, plays into the hands (and pockets!) of component and PC manufacturers. Once they have the equipment, they can then try to stretch it to the edge of its capabilities in order to provide a better experience. This has led to a complete sub-culture where patrons try to outdo each other on their PC builds, sometimes spending thousands of pounds for an exponentially small improvement in performance, but giving them bragging rights over their peers.

Of course technology tends to move so fast that within a week or two of their build going public, someone will have improved their design and posted slightly higher stats. This never ending battle to be king of the hill keeps some people busy for MONTHS at a time. And it doesn’t look like it will end any time soon!

There are countless websites devoted to hardware for your PC. They will sell you the latest graphics card or processor and tell you that you need it to compete in online gaming. The reality is that the PC you already have will likely run most games (it won’t play them all!) but it may do so very slowly, with very poor graphics rendering. This is where these sites know you will need to spend money to beef up your system. Generally people who go to mainstream shops and buy a PC need something that will browse the web and open emails for them. They may also want to watch Youtube videos and listen to Radio 4 but in general they won’t be doing anything too taxing.

PC gamers on the other hand tend to be a much more involved buyer. They will want a decent multi-core CPU with a low power draw. The GPU needs to be high end, with as many Petaflops as they can get for their money. Water cooling? That’s right, running water inside your expensive PC! The list of updatable components is not quite endless, but the number of iterations is. A low end gaming rig can be put together for a few hundred pounds, or you can splurge several thousands on a beast.

If you want to compete then you need to read up some more on the subject, and you also better have deep pockets!

EU Parliament fails to protect net neutrality

The EU Parliament today failed to pass a bill which proponents said would protect net neutrality in the EU. The vote, which blocked proposed amendments to legislation already adopted by the EU, could have significant impact on the availability of web services for consumer with a two tier ‘pay to play’ model the ultimate fear for neutrality advocates.

Net neutrality is nothing new. It has long been discussed and championed by eminent figures in the Tech world, like Sir Tim Berners Lee and Elon Musk along with major internet players like Reddit and Netflix. The fundamental principle of net neutrality is that all users should have access to the same services on the internet. The EU failure to implement these amendments now leaves the way open for content providers to charge for their services, or at least part of them.

It also provides an option for zero rated sites. This would offer free content from selected websites outside of a normal data plan, but the worry is that this may stifle innovation and lead to a closed shop system thereby denying everyone the same opportunity to view content. Basically, if you can afford to pay more, then you will see more. Hardly a fillip for emerging economies who are desperately trying to catch up with tech developments using the world wide web.

It is believed that the vote against the amendments was because of a fear that passing the bill would stall the introduction of a the Roaming charges ban (backlink to other article) which was voted for on the same day. The latter is obviously more of a hot button issue and was guaranteed to have widespread support from voters. The unfortunate issue here is that not enough people have been educated on the issue of net neutrality for it to be top of their agenda.

The issue will not go away. It is likely that a further bill will be tabled at some point in the future, and hopefully now that the roaming charges issue has been resolved, there might be a clear passage for such a bill. We’ll update if that happens.

EU Parliament votes to ban mobile roaming charges within the EU

The big news item today is the ban on mobile roaming charges in the EU, which was voted through today and will see roaming charges in the EU banned from 15th June 2017. Rightly this is a triumph for mobile phone users throughout the EU, and especially those who live in border areas which have conflicting signal strength which has led to bill shock situations in the past. Providers will no longer be able to pass on connection charges from that date, although there is an interim cap period from 30th April 2017 where operators will be able to charge no more than:

–          €0.05 per minute extra for roaming calls

–          €0.02 for each SMS sent

–          €0.05 per Mb of data used

Now while it might seem ideal that you won’t have these extra charges to worry about when on holiday, there is going to be a significant impact on the operator profits. That isn’t something they will take lying down. It is very likely that the cost of a standard contract will increase over the next few years to a point where the loss of connection revenue is irrelevant. And that is going to affect you directly. That £30pm contract you currently have is likely to become £40pm within a relatively short space of time.

Mobile operators will hope that people continue to buy new contracts. They make very little money from the service plan (and less after this ruling) but manage to get you to pay extra for a flashy handset, at interest rates which allow them to offset the small gains made on the service plans. I would expect that this business model will be aggressively pursued to keep shareholders happy.

So is there a way to combat any increase?

Well I believe so. Buying your handset outright is a much better option financially. A reasonably specced large screen 4G smartphone running the latest version of android can be bought for as little as £50 sim free, which means that you only need a sim package to get up and running. There are some notable players in this market such as Giffgaff  and the more recent (and untested at this  point) FreedomPop who offer a free sim with free calls, texts and data.

So while it might seem that the abolition of roaming charges is a fantastic deal for consumers, it might only be a short term benefit. It might be worth looking at the longer term to see if really does save you money!
