The All-New Super-Zero?

Well no, not really. Today I successfully completed my transition from streamline.net hosting services, who have served me quite well over the last 4 years, to my own private server based in France.

There are a few advantages to this move – for example I have complete control over all my hosting, what libraries are installed what permissions are given etc. I also save about £100 in hosting fees as all I have to pay for is the domain name every couple of years. Finally, my server is only running 4 websites, while the streamline websites would have been hosting quite a lot per server. So it’s a fair bit faster too!

So enjoy the all-new not-so-new Super-Zero experience! Regular updates continuing now!

CCIE – Bootcamp 2

One of the advantages of working for a company like Cisco is access to top grade training materials and courses – especially given that a big goal of the aNCE program is to quickly produce CCIE’s that can fill a consulting role. As a result of this goal, we had our second week of CCIE bootcamp in the week that just passed.

For those of you not familiar with the CCIE, it is a qualification offered by Cisco in several core areas of networking and awards the pupil with the prestigious title of Cisco Certified Internetworking Expert. It is also slated as one of the Top 5 hardest IT certifications in the world. As a result, in the 19 years it has been running, less that 33,000 have gained the qualification. In fact, only 3% of Cisco certified professionals have a CCIE, and out of all the world’s network professionals, less than 1% are CCIE’s.

The idea of the bootcamp is to give us access to mock CCIE lab exams and simulate the lab conditions, with the exception that we can discuss issues with members of our team and with the instructor supervising the class. This means that it’s a really strong learning experience while remaining hands-on and realistic.

In the space of 5 days, we had 5 configuration labs and two troubleshooting labs. The config labs ranged in difficulty and timescale – some labs were made to be completed in 6 hours, others in 4 and one in 8 (it was very difficult). The configuration labs consist of 4 switches and 6 routers which, while maintaining the same physical layout, are arranged into several varying logical network topologies:

Physical

Logical

The goal in this case, is to be able to make every device reachable, but while keeping to a strict set of guidelines and restrictions. The exam is also designed to trip you up – as a result it has never been more important to read an exam start to finish before you attempt the first part. The real exam is 8 hours long – 6 for the configuration and 2 for the troubleshooting. That being said, the troubleshooting is the only one restricted to the 2 hour limit. If you finish it in 30 minutes then you can use all the remaining time for the configuration if you wanted.

The troubleshooting lab is a little different. You are presented with a network consisting of about 28-30 devices. The network will be broken in several places, enough to create 10 distinct problems, which need to be completely fixed for points to be allocated. As a result this gives about 12minutes to solve each problem. The topology looks something more along the lines of this:

which is just total insanity, but someone has to fix it – and that someone will be a CCIE.

The configuration is all text-based so the exam provides you with the design brief, 3 sheets of paper, pens, a copy of PuTTY and notepad. You also have access to some command references in case you need to look for something incredibly obscure. As a result your screen ends up looking like this:

which can make it hard to keep track of things. I am using a tabbed console client here though which is not (unfortunately) be available in the exam. Another useful tool, for Mac users, is iTerm2 which lets you segment your screen into multiple windows.  There are a few linux solutions that can do the same thing, including screen and Terminator.

Hopefully this will give you a bit of a feel for what I have been doing over the last week – my first CCIE attempt is on Thursday, and I will not be passing it. It should be a good learning experience though and I look forward to doing my best for it.

 

Hands-On: The PSP Vita

It’s rare that I am in the right place at the right time – normally the cool stuff happens when I decide to stay at home, or have to study. It was the curse of my childhood that I missed the good parties and when I did attend them something bad usually happened.

So it was a nice surprise when I walked into a Game store in Reading yesterday evening, while I had some time to kill, to find that they had a Demo version of the PSP Vita. Even better was that the shop was practically deserted, meaning that I could get some hands on time with the monster.

The above photo shoes the PSP in the Hand – its a pretty big machine. At almost 2cm thick, you know it’s there, but once you adjust to the chunky feel, it almost becomes an extension of your arm. And it is light. While you can feel the Vita with your hands, the weight barely registers, meaning you don’t tire of it quickly.

The 5″ (127mm),m 16:9 capacitive, multi-touch screen has a resolution of 960×544 which struck me a surprising low given the 960×640 resolution of the significantly smaller iPhone 4, yet it looked rather good. Supporting 16 million colours, the clarity of the screen was better than that of the PSP S&L or the PSP Go, both of which I have owned in the past. Additionally, the backlight was strong and you don’t have to strain your eyes to see what’s going on. Finally, the sensitivity of the screen was spot on, allowing for smooth navigation of the menu systems both on the Vita homescreen and in game as well.

While we are on the subject of software – this PSP was running version 1.52 showing that the old PSP software has been ditched in favour of a whole new interface built around touch. That being said the menu system seemed to have no real structure – unlike the old PSP software which seperated your media into categories, the Vita seemed to randomly place its icons, mixing Games into Videos, Pictures and Music.

The dual analogs are a welcome addition to the front of the Vita, allowing for more interactive play in games like Uncharted which utilises one for the character movement and another for the camera – much like many of the current console RPG’s on the market.

The back Touch Panel allows for an added degree of interaction in games – although there wasn’t much on the demo model that supported it. The only game available on the device with back panel integration was Uncharted 3 where it was used for some actions like climbing ladders, traversing walls etc, however it really felt like this was a last minute addition to the game- some of the demos seen when the Vita was first announced showed some really interactive gameplay where the back panel almost became another dimension in itself but this wasn’t reproduced well in Uncharted.

Getting down to the bare circuits so to speak, the Vita has a quad core ARM Cortex A9 at its core, giving the software a really smooth feeling. App’s open quickly (although games can take a very long time to load) and you can swap between them instantaneously, while closing an app or game completely is as easy as a swipe of the finger. The GPU (Graphics Processing Unit) is the SGX543MP4+ which might look like a mouthful, but is also Quad-Core – giving the Vita an octo-core platform to base its games on. Hopefully this overhead will make for some really nice multi-threading in future games to bring really great performance.

In-game performance of the PSP was smooth…once the game loaded. Wipeout was fast paced and vivid (although that didn’t make me a better player) and the graphics were clean and crisp. While 6-axis control wasn’t enabled, Wipeout is said to support it, which would be a wlcome addition and work much better on a portable platform that on the console.

Everybody’s Golf, besides having a very Japanese twist (which I liked), has some cool capabilities too, such as using the motion sensor on the Vita for a first person game – you have to physically ‘look’ down the fairway to see where your shot went.

It was hard to tell from the limited time I had with the Vita but it did seem that there is no internal memory, which could explain some of the loading times for games. Personally, I am a little disappointed that a next-gen platform couldnt fit in a bit of flash memory – although no doubt its planned for a later hardware refresh.

Sony has confirmed that the PSP will launch in the UK with a 4, 8 and 16GB memory card available for it, but with no 32GB option some gamers have been more than a little annoyed. The shot below shows the memory card slot on the right, and the USB slot on the left.

In terms of connectivity, there will be two versions of the Vita available, one with just WiFi and one with added 3G (supported in the UK by Vodafone) allowing online play on the move. Additionally, both devices have built-in GPS and WiFi location services which makes the prospect of a maps app very likely.

The Vita is due for worldwide release on the 22nd February for both 3G and WiFi versions. So far 25 titles have been confirmed for US release, with the UK number seemingly a lot lower. The unit will be priced at £229.99 with games retailing at around £35.

Be vewy vewy quiet…

I’m hunting houses…

Well flats mostly to be honest. After a week of trying to study for CCIE and viewing wedding venues and prices, I find myself in the Holiday Inn in Reading with my colleague while we look for a place to base ourselves when the next phase of our work begins. While we will be working in two different teams, the scope of work will be roughly the same, so we will benefit from the shared knowledge and at the same time, it means I don’t have to pay a fortune to live somewhere on my own over here (I can imagine it costing me £2/300 more than sharing.

We’ve seen some nice places and some..no so great ones. The housing market in Reading actually seems to be pretty limited so we really need to jump on something once we find it. Out of the 5 places we have viewed today, there was two that we have both liked, although we seem to be revolving around one in particular, but there is still plenty to view in the next day so we shall see how the rest of the time pans out.

Meanwhile, CCIE study is starting to scare me a little. There are some parts which I am really confident about but at the same time it is far to easy to forget simple little things – like neighbour statements on non-broadcast multiple access frame relay networks using OSPF – this stumped me for about two hours the other night, even though I had used them on a previous lab.

Other tricky things I  have come across include Layer 2 protocol tunnelling – something I had never heard of before but is required to run ODR between two routers connected via a switch. So there is a lot still to learn and a lot still to practice. I will keep trying for the exam but part of me is pretty certain that I won’t get it the first time.

Time to wrap this up as there is another property to view – not many pictures I’m afraid as most of the apartments were actually occupied but keep checking out the photoblog.

Super-Zero is on strike!

With Wikipedia announcing its complete opposition the Stop Online Piracy Act (SOPA) it has also announced that tomorrow, the 18th January 2012, it will remove its English language website from the Internet for 24 hours. Several other websites such as Boing Boing and Tucows will also be joining in the strike. The website http://sopastrike.com/ has been rallying website owners, bloggers and anyone in opposition to SOPA to join together and blackout their sites from the internet for 12 hours between 8am and 8pm EST. Super-Zero will be participating. Both Super-Zero and the Super-Zero PhotoBlog will go offline at 00:00 GMT+1 and remain offline for 24 hours.

For those not familiar with SOPA, it is a bill introduced in the US which will allow domains associated with copyright infringement or file sharing to be erased from the internet, regardless of whether or not the site is US based. The bill also gives the US Justice department the power to instruct ISP’s to block the domain, stop advertisers from affiliating themselves with the sites, and stops paymnent services, such as PayPal, from doing business with the website in question.

THIS IS A POWER NO-ONE SHOULD POSSES.

The internet is a free medium. It always has been, and it always should be. It is the personification of our freedom of speech, thought and actions as human beings and to have that controlled by ANYONE is an infringement of our human rights, the right to share knowledge, experiences, msuic, ANYTHING. No-one should have the power to stop that.

The vote for the bill to be passed will occur on January the 24th 2012 - I urge you all, anyone who reads this, to please head over to http://sopastrike.com/ and register your support. If you have a website, blog, even a Tumlr – take it down in a show of what damage a censored internet can have. and tomorrow, the 18th January, Tweet, Facebook and share as much as you can about SOPA, the SOPA strike, using the #SOPASTRIKE on all your tweets.

It’s not often I believe in something enough to take strike action, so I urge you all to join in and support this movement. Keep the internet a free and open media!!
