USB-C

USB-C seems set to take over now

The future of physical connectivity in computer systems looks very limited. One day in the future I can foresee all devices connecting with a connection not too dissimilar to USB Type C. The reversible USB connector that was released a year back with the new MacBook was received with both positive and negative responses. For me, it was an incredibly positive product since it does a lot of things in one.

Apple just didn't get it right by releasing it with just the one connector. At the moment, adapters are still not everyone's cup of tea. In fact, for most people, adapters never will be a good solution. 

Anyway, the main point of this post is not talking about the MacBook, it's talking about something that I feel strongly about, physical connectivity.

One connector for all...

I don't really like this one connector for all since I've always liked the idea of different connectors for everything. 

You know, I remember when I made the switch to FireWire over USB about 7 years ago, I thought that buying all my drives with FireWire would be great since it's going to be the future of data connectivity. I know I was late in coming in, but I didn't expect it to be removed from all of my devices within a few years! I mean take my Macs for instance, my Retina MacBook Pro does have a Thunderbolt to FireWire adapter available, but this isn't ideal and it's expensive. My Mac Mini does have a FireWire 800 connector on it but the new models also require the adapter since they no longer feature FireWire on them. My PC is just as annoying however, since it doesn't even have a FireWire header on it. My previous PC (the Zebra, built in 2011) featured a Gigabyte GA-Z68X-UD3 motherboard which had 3 FireWire connectors (including headers) and then all of a sudden, an upgrade 2 years later to a Gigabyte GA-Z87-UD3H motherboard and a Haswell architecture, and I've suddenly got no FireWire connectors. 

Actually, one of the most annoying things is all of my PCI cards (not PCI-Express) which I've been using since about 1998 when I got my first PC, including a really old, but still useful, video capture card (circa 2000), no longer work on my system since there are no free PCI slots in my system (I have a serial port card and a TV tuner in them). 

A single connector for all also bring about the concern of overloading buses or whether or not everything is polled (as USB is). Speed can become an issue when one connector is used for everything. 

However, one connector for all is a good thing too, since every device you use will use that connector and it's easy to remember what you need to use the device (i.e. a USB-C cable). But many companies, such as Apple, are difficult and try too hard with their own connectors and make the one for all difficult. Look at the Lightning connector for example, every other smartphone uses Micro USB 2.0 or Micro USB 3.0 meaning you can share your charger with any other smartphone user; that is everyone except iPhone users. It never works. One for all is too difficult.

Complications also arise when you are working with very specific applications. I for one still use the 1980s RS232 standard for many things such as electronic circuit boards for experiments (although I'm looking into using a RPi for this in the future) and for control commands for my projector. With a connector like USB-C, this becomes more complicated since RS232 was a highly simple connector, it becomes harder to emulate old standards. 

Another even more annoying thing is having to buy an adapter to make it work with your older devices such as serial port devices. These devices may be hard to come by, but the bigger issue is if we end up needing all these adapters we've got to pay for them, and more specific adapters will probably be fairly expensive.

Here is a comparison table showing how Thunderbolt has changed over the years:

Version Maximum Speed Maximum Power Output Connector Type
Thunderbolt 10Gbps 10W Mini Displayport
Thunderbolt 2 20Gbps 10W Mini Displayport
Thunderbolt 3 40Gbps 100W USB-C

Notice any similarities between Thunderbolt 3 and USB-C that was announced on the new MacBook? That's because they will likely merge.

The conclusion

Here's my solution: make the one connector for all a reality, just keep the old connectors alongside this new connector, thus giving people, like me, the option to use older connectors without needing to buy the adapter. This keeps costs down, but also leaves users of older devices able to continue to use them. Don't cut out USB Type A and replace all mice and keyboards with USB-C connectors. 

We cannot live in a world where we need to keep all of these dongles for everything, it's simply ineffective and expensive, especially when one breaks down. I believe because we have come from a world of loads of different connectors into a world wanting a single connector for all that we will be faced with many problems. This is particularly the case with industries such as the music industry, where devices of today really lack in the connectivity side of things. I mean the world got rid of the Gameport (or MIDI port) without any major problems, but for those who had purchased MIDI devices that used the Gameport-style connector as the input, they had to go out and buy adapters or get new devices. The change can come on too rapidly, especially for some. The slow but very painful disappearance of FireWire in the last few years has made it's mark, even for me since I can no longer connect my FireWire drives to my PC (I can with my Mac mini thankfully). And now companies are phasing out audio jacks and in particular the multi audio jack system, and all in favour of USB or single audio jack solutions.

Tesla, who just so happen to be one of my favourite companies, are unveiling their latest electric car - the Model 3. I am very excited by this mainly from a technology perspective but also from an environmental point of view. 

Teslas current lineup of cars are absolutely stunning, and it may seem like a dream right now, but I am very interested in the range and some time in the future I would love to own one (it will likely have changed by the time I get around to looking at buying one).

Tesla are a fantastic company who build things to an outstanding degree as I noticed when I was in one of the Tesla Stores. They also innovate way more than other car manufacturers, so kudos to them. 

I am excited by the Model 3 however as it will have a lower price point than the other models and it could possibly be the next car my parents buy. The future is electric and I'm hoping the Model 3 proves this further. 

For the very first time since buying my 2012 Mac Mini in 2014 I have reformated it with a fresh OS X install. There was no particular reason for this other than wanting a fresh install of OS X with the very minimal install again - too many files on my system were taking up my drive, so it was just time. The system was still running absolutely as it was when I bought it, so it was nothing related to that. Just saying, Macs don't need that kind of reformat anyway.

Anyway, since this is the first reinstall of OS X on that machine, I thought I'd give my configuration script a try. It really is wonderful, and it's really all thanks to my friends Ben and Merlin that it's as good as this.

The script looks like:

Bash
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install rlwrap
brew install Caskroom/cask/smlnj
brew install Caskroom/cask/osxfuse
brew install sshfs
brew install python
brew install homebrew/x11/swi-prolog
echo "Insert Dropbox path:"
read input_variable

echo "export $DROPBOX=" >> ~.bash_profile
echo "$input_variable" >> ~.bash_profile
if [ ! -d ~/Pictures/Screenshots ]
then
    mkdir ~/Pictures/Screenshots
fi

rm ~/Library/Preferences/com.apple.dock.plist
rm ~/Library/Preferences/com.apple.finder.plist

sudo cp "$DROPBOX/Mac configurator/configuration/com.apple.dock.plist" ~/Library/Preferences/com.apple.dock.plist
sudo cp "$DROPBOX/Mac configurator/configuration/com.apple.finder.plist" ~/Library/Preferences/com.apple.finder.plist
defaults write com.apple.screencapture location ~/Pictures/Screenshots;
killall SystemUIServer

So once I got my Mac up and running and Dropbox installed, I run this script to copy all the necessary files across to their places, which restores my Mac to how it should look (i.e. it makes Finder and the Dock identical across my Macs). I've highlighted line 12 because it is where my Dropbox directory is put into my Bash profile so that I can reference it from any script easily.

By the way, this is not me saying that Bash is beautiful, because the syntax is horrible. All I am saying is it is a pretty powerful little shell scripting language.

As I'm sure anyone who read my blog for technology related stuff will know, Moore's Law is a fundamental 'law' that defines that the speed of computers will double every two years. It's not entirely the case but it holds true for the majority of systems produced.

The law is more of a theory of a computer scientist called Gordon Moore, one of the founders of what is now Intel. It was theorised in 1965 and what it really stated was that the number of transistors that can be crammed in to one integrated circuit will double every two years. 

Intel call this a tick in their 'tick-tock' cycle. Examples of Intel CPUs include the Sandy Bridge range (tick) when compared with the Ivy Bridge range (tock). Both of these ranges were based on the Sandy Bridge architecture. The Haswell architecture which was the next tick could fit twice as many transistors in the same size of integrated circuit, following Moore's Law. 

But on the release of Broadwell, which was based on the Haswell micro-architecture and was the successor 22nm Haswell, we have arrived at transistors that are only 14nm in size, compared with Haswell's 22nm transistors this change is huge. The next step after 22nm according to the International Technology Roadmap for Semiconductors will come in at 10nm. Currently, Skylake, which is the current range of Intel APUs and is a tick in the tick tock cycle, is facing several problems with going further. For the very first time in the history of Intel's tick-tock cycle, there are going to be two ticks (tick-tick-tock). Why you may ask?

The answer is that Moore's Law no longer holds true with current fabrication techniques. In fact 10nm is posing such problems that it has been delayed until 2017. Cannonlake (formely Skymont), which will be the tock in the cycle will succeed the successor of Skylake, codenamed Kaby Lake. It will drop the size to 10nm. From here on however, there is considerable worry about whether or not we can go any further. We may see for a few years that computers cannot get any more powerful. What worries me is that the companies may use this to make money out of us at no extra cost to them (since the technology will change but the systems will be no more powerful).

So what's the next step then? Quantum computing? Chemical based computing? Biological computing? Good question. 

For the foreseeable future I would imagine that quantum computers will be the future, since they currently already exist. What worries me about the future is how will devices we currently use (such as the world wide Internet) interface with these new devices? I worry greatly about this and how the transition will turn out.

Back in the day, when Netscape and Microsoft started the First Browser War, Internet Explorer and Netscape Communicator fought to become the most popular browser. 

Ultimately, to many people's dislike Internet Explorer won and Netscape disappeared. Netscape Communicator evolved into Firefox. At this time Internet Explorer's share of the browser market kept growing, largely due to the fact that it was bundled with Windows until the EU decided to make it compulsory for Microsoft to include a way for users to change to other browsers easily.

Since then, I have become a web developer, and I stopped using Internet Explorer again in favour of Firefox and eventually Safari. I'm not the only one who stopped using Internet Explorer, however. Year after year the share for Internet Explorer has dropped. Here are the statistics that show this for November 2015 from W3 Schools:

2015 Chrome IE Firefox Safari Opera
November 67.4 % 6.8 % 19.2 % 3.9 % 1.5 %

And here is a set of statistics from 2002, 13 years ago (when I used Netscape I'll have you know!)

2002 AOL IE Netscape
November 5.2 % 83.4 % 8.0 %

But why is this the case?

Microsoft just didn't care

Microsoft was very bad at developing Internet Explorer between iterations, they thought because they had a huge market share that they wouldn't lose it. I only realised this after becoming a web developer myself, since developing for Internet Explorer all the way up to IE9 is very difficult.

Even if other browsers had features for a year or two, Internet Explorer would most likely not get these features for a long time after. Prefixed support wasn't even there. Microsoft, as always, just thought it was ok to just leave it. 

Microsoft only cared when Internet Explorer started to disappear.

The future

Microsoft will have a lot of catching up to do with Microsoft Edge since Internet Explorer got them the bad name of the browsers. I personally do not see this happening in a way that will transform the share so that Microsoft has the upper edge again, but I can see them regaining some of the lost ground with it.

Edge is a fantastic browser, especially from Microsoft. Edge really does support cutting-edge technologies and implements most of the web standards well.

Today's post is about managing a large website from information architecture to the whole core of the website.

Since I relaunched my website with the refurbishment to last for the rest of my website's life, many small tweaks have been brought to the design. Many of these tweaks were based on small suggestions as well as the occasional large one (like building my own menu system). 

A website in some cases does not seem like an ongoing job, but for my own personal website, my web developerness always encourages me to do more. Knowing when to stop is a very difficult, if not impossible, task. There is always something new that could be brought to the site.

I often talk about how proud I am of my personal website since I wrote the whole thing from the gallery to the blog to the whole design, but what I don't talk about a lot is the content on my website.

As I'm sure you will agree, my website is rather large. Not only are there several pages of blog entries on my website, there are over 80 articles in my tutorials, I have quite a few reviews and articles, there is lots of information on the projects I'm working on, information on me, my pets and family, a gallery, information about my software, including my page dedicated to Zenith, a lot of stuff on university, some developer tools, newsletters and so much more. 

Information architecture

The information architecture (IA) of a website is crucial and is the very first thing that should be considered when developing. If you are interested in web development you will likely already know that putting an index.html or default.html page in a directory means that the URL does not need a dot, so http://www.test.com/about/index.html can become http://www.test.com/about/. 

Sticking to a procedure of putting the index or default page into a directory gives the site a better architecture also. Nested directories like articles/ and articles/computing/technologies.html are nicer than file paths like articles.html and articles_computing_technologies.html. 

Managing content

Content can be difficult to manage on a large website and while this website is reasonably small compared to some other websites, including ones that I've built, but none the less, I do have a very strict system in place to control images, CSS, JavaScript, PHP and text files that are considered assets to the website.

Site dependant content should be stored together in one central location on the website. I tend to use a folder called /assets/ as my content folder. Inside there exist several folders, particularly /assets/images/ and /assets/css/. This means that all images shared across the website can be found from this area.

Since the middle of my childhood, I have always kept a close eye on computer connectivity and it has always been one of my biggest interests in computers.

Very recently I started to think a bit about what connections are on their last legs in their lifespan - ones that probably will no longer be used in four or five years, and I came up with a list:

  • IEEE1394 or FireWire. FireWire is one of my favourite connectors for disks because it is relatively inexpensive compared with what most consider its successor - ThunderBolt. Yet more and more wealthy professionals are moving to Thunderbolt, leaving the consumer market with USB 3.0. USB 3.0 may be faster than FireWire in some situations but push FireWire development further and we could see it back where it used to be - USB's big brother. However, development like this seems incredibly unlikely and FireWire, as great as it was, seems doomed.
  • eSATA and SATA. eSATA or external Serial Attached Technological Attachment was an attempt to bring SATA speeds to external devices and remove the bridge that both FireWire and USB required to communicate with such devices. eSATA keeps up with the speed of the core SATA implementation so it's about as fast as its internal connector. eSATA has never kicked off properly though and its only real purpose is to act as an external drive interface. SATA on the other hand is huge at the moment, but like eSATA, in my opinion, doomed. I say this because in the enterprise there is SAS - a much better alternative to SATA and more and more consumer laptops are moving to PCI-Express-based drives and it will likely not be long before those who care for speed move to PCI-Express boards for their desktops too. From this, I do believe that eSATA is doomed and that SATA is a connector that will soon become very low-grade.
  • DVI. We've been saying DVI is finished for years and sure on consumer systems it is pretty much gone, but in the business world, it's still there. My first PC to have a DVI connector was in 1999, my last monitor to use DVI ran until 2011. Since then I have moved to DisplayPort for the majority of cases and HDMI also (due to the fact that I run multiple computers from the same monitor and the majority of monitors feature multiple HDMI ports but only a single DisplayPort). Most business systems are built for budget and as part of this include budget monitors featuring only VGA and DVI. Some low-end monitors are starting to appear with DisplayPort (since it is royalty-free it is cheap to include). This new addition may signal an end for DVI in general.
  • Optical audio. Optical audio is one of the greatest inventions in the AV industry but the TOSLink connector that we use today is something of a novelty. More and more television sets are dropping this connector since the all-in-one HDMI offers uncompressed PCM 7.1 audio as well as video over one cable. This means smaller packages too, as HDMI is a much smaller connector (internally) and is already included in almost every modern television.
  • 3.5mm jack. Phones will likely be the first to get rid of the headphone jack, and ultimately computers will ditch the 3.5mm jack and replace it with USB (as should have been the case several years back).

You may ask what about PS/2. PS/2 being one of the oldest standards in connectivity still in use still has not disappeared from its brethren (the parallel and serial ports). PS/2 probably will not disappear for some time still since, unlike USB, it's relatively cheap to implement and that makes it good for business. For gamers, it's the ability to send an interrupt directly is incredibly fast and unlike USB it does not rely on polling, so it still could remain popular in that market too. VGA is also a long way from being replaced in the server market, particularly in rack mount servers, where there needs to be as much room as possible for disk drives and little need for a powerful GPU.

If you are interested in knowing about the benefits of the old PS/2 standard vs the ugly USB polling system, take a look at this article.

This year, Apple's September event was, in a word, mediocre.

For those that did not see the event or know much about it, you can read more in the previous post on my blog.

The majority of the event focus on iPad. The new iPad Pro that Apple launched is 'the biggest thing to happen to iPad', literally. The iPad Pro is a 12.9 inch iPad (as predicted) which also has a new Smart Connector to connect a specific external keyboard. It also comes with a digitizer known as the Apple Pencil. The Pro is designed with business folks in mind.

The other major announcement was the iPhone 6s. Again, this was pretty much predicted down to the last feature. As expected, it supports 4K video recording and has a 12MP camera. The other new feature that was added was Live Photos, which are basically small video recordings take with photos and attached to them. This will work with El Capitan and iOS 9 and hopefully other devices in the future so that we can relive those photographic moments. As someone who takes a lot of photographs and loves to make memories, I really like this idea. The 6s also features faster Touch ID and more, but these features were pretty minor in the grand scale.

Apple also announced the next generation of Apple TV. This model brings solid state storage to the device and a remote control with both motion sensors and a microphone. Personally, this was the biggest announcement of the day. The storage is included so that app from a new dedicated Apple TV App Store can be installed. 

There was no mention of Macs, but there you go.

Finally, I have managed to get Windows 10. And the good news is it was so easy to install on my Mac (not like my PCs). 

Windows 10 scaling features work well, unlike Windows 7, 8 and 8.1 so I can finally use the high DPI of my Mac's display with Windows. I've been waiting for some time (since August 2014) to use Windows on my Mac (I had Windows until April of that year on my older MacBook and I've always had it on my Mac mini as well) and it's nice to finally have it again!

My tablet has just finished upgrading to Windows 10 as well due to the fact that unlike the installer Microsoft has been giving out, 'burning' a plain old ISO to a USB drive on my Mac works.

I will finally get round to doing my review. In general, I'm positive about the experience I'm going to have with this OS, considering Microsoft's tick-tock cycle of good OS (ME, XP, 7, 10) then bad OS (2000, Vista, 8).
