Backups how often do they get done.

Published by calhoun on October 20th, 2010 - in Technology

hard driveThe question of backups is one that faces every system administrator. The real question is weather they have a backup in place and is it up to date enough? How many organizations do not have a practical backup policy in place?

Our backup strategy is good, but has room for improvement also.

All new work we do is maintained via a SVN repository or something similar so this qualifies as code level backup, but what if that goes down? Well, in all likelihood we’d lose a lot of data, and have to revert to our local copies to rebuild a new repository so not all is lost. Many firms undoubtedly do not do this and if their development machine goes down they lose it all.

From a backup management point of view, ideally data should be backed up in the local machine, local network and off site, after every change. Of course, if you have a multi-gigabyte database this might not be a practical solution! Balancing the weight of the likelihood of failure against the frequency of significant changes is a task that needs to be considered carefully.

If you want to discuss a backup strategy and solution we’ll be willing to have a chat with you.

Linux a serious option for children heres why.

Published by calhoun on October 18th, 2010 - in Internet, Technology

Linux vs MicrosoftMany of you know me as being a pro Linux kind of guy, it makes sense really! Its free, its reliable, and it gets the job done with a lot less hassle than doing the same work on a Windows machine.

I however am not the only one who supports the use of Linux. Jack Wallen speaking from TechRepublic has actively encouraged the use of Linux for children. I agree with him.

Key points from what he says over at ZDnet is that Linux should be aimed at children and would make an excellent choice for use in schools – some places have entirely switched computers over to Linux in schools and many University computing departments make use of Linux also. Kerala in India has completely switched all of their school computing away from Windows to Linux.

Points of Note:

  • Virus, Malware and Security – Given that Viruses and Malware are for all intents and purposes do not exist on Linux this is a clear move, He points out that children are likely to open things they shouldn’t and are not going to be supervised constantly on the computer. Security models on Linux are by design far more secure than Windows.
  • Cost of Ownership – its free, and this surely will fit in line with Government budget cuts no longer will they need to pay expensive annual license costs for copies of Windows or Office (which can be and should be replaced by OpenOffice).

With this in mind, perhaps its time to send a few letters to local MPs,  get a campaign going to convert school computers over to Linux.

Steam powered computer on the way.

Published by calhoun on October 18th, 2010 - in Technology

Steam Based ComputerIt is not likely that this will out perform a modern age computer so the purpose behind building it is scientific rather than technological. Designed in 1837 by Charles Babbage the computer is big (truck sized apparently) and uses steam to run its mechanical parts.

It dates from the time before computers even existed, and a campaign lead by John Graham-Cumming seeks 50,000 people to fund the venture to build a full scale working version of the unit. Parts of it over the last 173 years have been built but never a complete working model.

He plans to take a number of steps should he get the funds needed: digitizing documents originally made and interpreting them, building a 3D model to help with debugging the massive machine and of course building the machine itself!

UK Government not prepared for Cyber attacks

Published by calhoun on October 16th, 2010 - in Internet, Technology

Cyber SecurityIt seems that whilst London has been busy fighting over where money should be going they may have forgot there is a nation to run. This week has seen some serious warnings about the failings of the UK National security preparations. Government Communication HeadQuarters (GCHQ) director Iain Lobban has warned of a threat of cyber attacks on the UK infrastructure.

A former advisor to the whitehouse working now at security firm RSA highlights that international efforts must be made to deal with the threat of cyber attacks. There are countries that still turn a blind eye to the activities so long as that they are being directed from outside their borders. These nations must deal with activities such as this – and I suspect these countries may belong to the middle east.

The house of lords have also held a debate for 2 hours into the subject of cyber defense. How productive that may have been im not sure, but the conclusion was that the Government needed to take action so even if they are clueless the right advise was suggested anyway. The debate came about as a result of an EU recommendation of an NATO-EU joint effort to protect member states from such threats. Of course, that was published in May, so its good to see the Lords are up to speed!

Testing and Development shouldnt be fighting each other

Published by calhoun on October 15th, 2010 - in Technology

Testing is an important part of the software development life cycle. I was shown this image today and it got me thinking. We are currently evaluating, and likely to press ahead with completion of purchase in  the next week of a new project management system.

The new system will have an integrated source control monitoring system, code review system and bug / feature tracking capability. This fitting in with our somewhat agile development policy.

The number of organizations that seem to consider that software testing is a separate entity and goal from software development is quite surprising. We actively encourage testing as we go policy, and indeed even after a project has been accepted as completed by a client, in many cases we are likely to keep the project alive beyond that. Taking the time to improve the technology so that next time a client comes along and wants something similar, we can role out at a fraction of the development time and get on with our new projects.

The end user must absolutely be involved in these life cycles, they ultimately will know more about the daily operation of the software than anyone else. From day one a client will be granted access to our issue tracking software. They will be able to submit requests for features and report bugs, which the development team will investigate and the accounting team will bill for where applicable.

This allows us to give better estimates in the future we have the information on the system – we know what issues we ran into when doing things previously and this helps us estimate better. It shows how many bugs were encountered, how much code was used this comes together and helps project management figure out whats going on, when to expect things and allows us to deliver projects ahead of schedule and within budget.

Ireland: 3 Strikes and out is just not good enough.

Published by calhoun on October 14th, 2010 - in Internet, News, Technology

Scales of JusticeThe UK Parliament chaired by the dark Lord Mandelson forced through the Digital Economy Bill  designed to give the music industry severe power over the Internet has today received a major blow to the credibility of the act. A Judge at a High Court in Ireland has ruled that the 3 strikes rule just is not good enough.

One ISP, UPC stood defiant of the Irish Recorded Music Association (IRMA) by refusing to cooperate with the 3-strikes agreement which IRMA had negotiated with the largest ISP. The deal meant that the IRMA had to achieve cooperation with all ISPS in order for it to be valid. They stood by their customers, and they were brought to court over it.

Mr Justice Peter Charleton ruled that an injunction against UPC is not possible as Ireland does not have a legal framework to support it and more importantly that it contravines European Law.

High Speed Broadband is coming ….

Published by calhoun on October 12th, 2010 - in Internet, Technology

Broadband Pipe… then again, Christmas is coming also, actually, its 73 days away at the time of writing. Anyway, a study of UK Broadband has been conducted and has found once again that the UK is lagging behind many European counterparts.

Over at the Telegraph, one commenter points out that in Finish Law, access to high speed broadband is a right sitting on his 130Mbps standard home Broadband kit one wonders if the UK will ever catch up on the Broadband race.

From the results conducted by Broadband-expert.co.uk , it is showing that Liverpool has the fastest average connection rate weighing in at a ‘massive’ 7.72Mps. Given that the usual package offered is an 8Mbps this is quite impressive, relatively speaking anyway. However is nothing compared with Virgin’s top 50Mbps Package! The Northwest England area seems to have a significant amount of “high speed”, hardly surprising – Manchester is a second level point of presence for the Internet hooking up with the London Lynx and up north to the Trans-atlantic links. I would therefore have expected the connectivity to be higher in this area.

On the other end of the scale, the folks living in Dunfries unfortunately are seeing speeds closer to 2Mbps hardly a viable speed to call high speed. The results however have no distinction between different types of connectivity – fiber or adsl. Even taking these into account however, Broadband here leaves much to be desired.

BT may be finally under taking the roll out of fiber, which they should have done years ago but I suspect even with that, we will still be far behind Europe.

Virgin seen in suborbital space.

Published by calhoun on October 11th, 2010 - in Technology

Virgin Galactic TestPerhaps not quite the virgin Mary or an Angel coming down to see the minions on earth, but she is called Enterprise and under the watchful eye of Virgin’s chairman, Richard Branson, she made her first flight through the sub-orbital level of the atmosphere. Bringing space travel one step closer.

The craft was taken up by aircraft rather than launched from the ground. The craft was then released and allowed to glide back to base successfully.

The commercial nature of these flights pioneered by Virgin may be dubious with a single flight merely taking you outside of the atmosphere for a few minutes of weightlessness. However it is an important step for space travel, and later when colonies exist on the moon and beyond,  Virgin Galactic are likely to be one of the forerunners of commercial traffic.

The company state they are nearly full for the bookings for their first year of operations, a number expected to be around 500, giving the company in the region of $100,000,000 for the venture. We poor people can only hope that Easyjet decide to venture into the low-cost space travel budget. Although im not sure how beneficial that will be…

Google Trials Driverless Car and no one was killed

Published by calhoun on October 10th, 2010 - in Technology

google carThe guys at Google have apparently been testing Driver less cars releasing them on the unsuspecting population of California with a whopping 140,000 miles on the clock it is an impressive display of technology. Driver less cars are not exactly new, but I am not sure they have been as extensively tested in real life situations as the Google team have put their implementation through.

A Software engineer at google in his blog observed that there are benefits: Reduction in death caused by drivers, energy saving and freeing up more productive time. These benefits are definitely a good thing, provided that it works. Reassuring the public he announced that although the cars are driving themselves, safety precautions are in place. Namely a real driver that can at an instance take over should there be a problem and a passenger is monitoring the software powering the car constantly.He also says that local police are informed, I’m not sure if that’s so that if something does go wrong, they can legitimately blame the computer and not take the responsibility.

He further observed: “While this project is very much in the experimental stage, it provides a glimpse of what transportation might look like in the future thanks to advanced computer science.” I can see it now, your sitting in your car, completely blacked out from the outside, Google Maps on the front window, Ad-Words on the side windows, and your search results on the back window. How disturbing.

At least, Google is not the only company working on this technology, and I am certain that the big Car manufacturers will want to get into this field before it becomes the main means of transport in the future.

Facebook pulls out a shiney patent on GPS

Published by calhoun on October 7th, 2010 - in Technology

Facebook PictureThe guys over at Facebook have been granted a patent which could threaten a large number of companies from Social Networking to Satellite Navigation technology.

The patent application, filed in 2007 titled “Systems and methods for automatically locating web-based social network members” comes equipped with an almost PhD thesis level of vagueness.

The patent describes in short, Facebook places service but the ramifications could extend beyond that service – Tom Tom has a friend finding service in some of their higher end GPS units which the patent could potentially be interpreted as infringing despite Facebook’s service becoming available after Tom Tom completed their technology.

Erik Sherman over at Bnet does a good job at analysing the patent. Key points being that despite the most obvious technology used to update the service with location being GPS, the patent does not actually limit to this – there are wireless network based location services out there using this to update the service would fall under the remit of the patent.

It will be interesting to see how the big companies such as Google react to the threat of this patent to their own products that are doing the same service entirely. They might want to bring a challenge against the validity of the claim on the basis of being a general vague building block that no company should be entitled to a patent on as it infringes on innovation. Alternatively they may just opt to negotiate a licensing agreement with Facebook.
