Windows XP was launched to the public on 25th October 2001.

Windows XPA major upgrade from the MS-DOS based versions of Windows, XP was based on the Windows NT kernel which streamlined many of the operating systems core functions.

Streamlined and faster it quickly won consumers hearts and although Microsoft have long pulled support for the OS, it still remains viable for some applications. Apparently it still has 25% of the desktop market in China.

The major standout for me though was the advances XP made in security thanks to it's NT genes. This security improvement has continued to evolve through the clunky Vista, the smooth 7, the ordinary 8, the non-existent 9 and lately 10.

Overall, I liked it much as I like 7 and 10. Wonder where from here?

Android watch

 

Google maps and its mobile app service is not new. The introduction of the new Android Watch will make wearable navigation a must for the geographically challenged amongst us.

Smart, wearable on your wrist communication and navigation? Even Dick Tracey would be jealous.  

 

Tired of seeing a massive desktop tower protruding from under the clean lines of your office desk? PC towers were once all the go, room to put more cd and hard disk drives and upgrade the RAM and so forth. But is that really necessary now? In our experience when it comes time to upgrade your tired old desktop it is more expensive generally to retrofit the dinosaur than it is to buy a new system outright.

A PC that comes with the motherboard, power supply and sometimes a processor and all the plugs needed to make it a fully functional PC. Typically a hard drive, random access memory (RAM) and maybe a video card can be added by the user.

We know that many folks on the outskirts of Dubbo have had wireless access to the NBN broadband network for a good while now. A lot of people however have been waiting for the fixed line rollout to commence within the Dubbo city limits. Well it has begun today Wednesday the 23rd of April!

Dubbo NBN mapWe have been told that the construction teams will not leave town until the roll out work is complete. This will mean fibre optic cable to most city streets if not to your door with greatly increased capacity and speed. If you remain on the old copper network your service will be unaffected but be aware it will no longer be maintained by Telstra. 

I remember my father telling me about IBM's new computer in Adelaide in the 1960's. It took an entire floor of an office building and could add, subtract and multiply like a boss, just couldnt do division! That is when it was running, instead of transistors the machine used valves and was prone to continual breakdowns. Sometimes when an insect was attracted to the heat and light of the valves and would short the whole system. Yep, you got it. That's where the computer term "Bug" came from. 

But check out the difference in data storage, graphically shown in the following pictures.

Data is the core of what we do with computers yet one of the most neglected tasks is backing up your stuff! This is ironic considering a large amount of what we do at Dubbo Computer Repairs is data recovery. Criminals realise this also. For example the spate of data encryption locking viruses that have been promulgated recently. Targeting the gear you hold dear like documents and photographs.

Well surprise, surprise the scammers are at it again! This time with an scam similar to one I wrote about in December last year NSW Office of State Revenue. This virus hook is also delivered by email and leads to one of those nasty cryptolocker variants.

 

Australia Post Email ScamAustralia Post Email Scam 2The way this email starts is with an email indicating that you have a parcel to pick up from the post office. It looks legit, even though Australia Post do not send notification of this by email. Parcel notifications still come from those increasingly endangered but much loved creatures, your local Postie, straight to your door or your mailbox.

 

If you click on the link it takes you to a remote website that prompts you to enter a CAPTCHA code so you can track your item. That is when you allow the malware to be installed on your device.

 

 

#Update 11th Dec 2014

**If you believe you are at risk from this virus it is recommended you shut down your computer IMMEDIATELY and call for help!**

No one likes getting hit with a speeding fine!

I can tell you what is likely to be worse. A fake email from the NSW Office of State Revenue stating you have been pinged. Then when you click on the email link to find out the bad news it infects your computer with a Trojan (Virus) the encrypts your computer data and gives you 48 hours to pay some lowlife Russian criminal $300 for an unlock code or your data is gone forever, Merry Christmas!

This virus is commonly known as #Update 10 Dec 2014 ("Cryptolocker" or "Trojan.GenericKD.1430364"  this is a cryptolocker fake) TorrentLocker.

 

Brain

Central Processor Unit

 

So you want to buy or build a desktop computer. Where do you start? Probably the Central Processor Unit or “CPU” because, as the name implies, the CPU is central to everything your computer does. It is the brains of the outfit. Regardless of what else you adorn your desktop system with, if engine is not powerful enough to do what you want you will suffer poor performance.

 

So how can we tell the performance of one CPU compared to another? A good while ago (talking early 1990’s here) judging a CPU’s performance was pretty simple. You judged how many clock cycles (known as frequency) it could perform per second, 1 frequency unit = 1 hertz. Back in those days it was run in Megahertz “MHz”, 1 Mhz = 1,000,000 hertz. So you saw one processor was 60 MHz and another was 75 MHz. No problem, obviously the 75 MHz would perform better.

password

 Every experience with technology these days seems to come with a password or login. From social media like Facebook to email and online banking.

Most log ins require at least an eight digit password. Why? With the shear number crunching ability of modern computers a criminal with an appropriate program can crack a six digit password in under five minutes!

A password with eight digits is 10,000 times more secure than a four digit password.

It is also vitally important that passwords are not easy to guess, like 1234 or 5555 or your birth date (No one would know that would they? Just everyone on Facebook!). A good password has at least eight digits made up of unusual characters, for example [&wE1*C9z] and it is also important to have different passwords for different log ins.
