  • All About Opportunistic Locks

    Opportunistic locks are incredibly useful when it comes to clients synchronising their files for caching across a network, it allows anybody to place a lock (more so known as an oplock) on any files that are residing on a server. The main reason this whole process is existent is because it allows for the data to cache locally, which improves on the all around response time of your server (as well as manages network traffic, keeping it more open for your users). The main reason oplocks are used is because network re-directors have found a use for them within clients remote servers (including some client applications that may be on any local servers).

    The locks themselves make sure that clients data caching and coherency work perfectly in every sense, it’s essentially made to work with multiple clients at once. To make it a lot more simple, if the data is proper, then the data on the servers (as well as amongst all the clients) is in proper order (known as synchronized). Every single file that requests an oplock has to go through a requesting process, as well as being opened for an asynchronous operation. Be aware that these locks aren’t commands by the client that are getting fed to the server, their actually requests from the client to the server itself. Many clients find the whole process quite appealing, the server allows for these locks whenever the circumstances are right

    Whenever an application that is stored on a local server is requesting access to a remote file on the server, oplocks aren’t necessarily “seen” by the application itself. It’s the network re directors protocol (as well as the servers) to open and close the locks accordingly. Remember, local applications shouldn’t request any oplocks from remote servers, as all it will do is return an error message. Oplocks themselves have a very limited range of things they can accomplish, they are usually used to test the quality of a network re-director or a server opportunistic lock handler.

    There are three main types of oplock, which I will cover in more detail in my next article on the subject, but in brief they are; Batch Locks, Exclusive Locks and Level 2 Locks. Batch Locks originally were designed to cope with the mechanism by which MS-DOS based batch script files repeatedly open, read/write and then close the same file in a short space of time and improves execution speed by providing a high speed cache.

    There are terms that people may not be completely aware about when it comes to the management of oplocks, things like the “coherency of data” can be confusing to some. Seeing as the locks themselves only provide a small amount of benefit to servers, it’s still better than nothing. It’s possible to minimize the amount of “damage” your application will have on the clients using it, as well as the impact the clients actually have on your application itself. This is possible by allowing them to share data as much as they possibly can. This minimizes the amounts of access levels you need on your server in the process, which of course allows for more flexibility in a sense.

  • Setting up Office 365 email on Android devices

    Windows 8.1Windows 8.1 is quite and intriguing operating system, some people may think that there isn’t much difference considering the version number, but these people couldn’t be anymore wrong. Windows 8.1 is said to bring to the table a better search engine, a better way to manage applications (through the use of the Windows Store), as well as a start-up screen that always has the latest updates on deck for you. It’s pretty extravagant, the operating system itself has put in additional features in such a short amount of time. This goes hand in hand with the BootyBay article posted on here, as 8.1 seems to implement the use of Windows Store, but it also allows you to sideload different applications a little bit easier. If you aren’t aware of what that means, head on back and read up on the article explaining it all.

    Another useful feature to keep in mind when talking about Windows 8.1 would have to be the pure fact that it’s relatively newer. Things are going to be a bit more stable than they usually are, as well as a bit more faster and cleaner. It’s always a good idea to upgrade whenever possible, and operating systems are no different when it comes to this rule. Some people are happy with what they’ve got, while others always wants the “new and improved” thing available on the market. You can’t blame them though, Windows 8.1 does look pretty sweet so far.

  • Windows Smart Phone Range

    Nokia Lumia

    Microsoft have been making it their duty to introduce new and improved mobile devices and operating systems to the market, they really feel like they’ve got what it takes to bring a whole new ball game to the course (if you know what I mean!). Smart phones have been a cornerstone in society these days, people have become accustomed to being able to just open up their phone and contact somebody; even if they don’t have to call them. With all of the social media applications and such out there on the market now, there really isn’t a reason you shouldn’t have hopped on the smart phone train. If you want a phone that is as sophisticated as yourself, you can’t go wrong with a Windows smart phone.

    There are plenty of different builds and brands available when it comes to purchasing your first (or simply newer) smart phone, there’s also a lot of things to take into consideration. Are you the kind of person who’s going to be using your phone for work and business? Or are you just the kind of person who wants to be able to connect with your friends at the push of a button? No matter the case, windows smart phones are exactly what you’ll need to spice up your life a bit.

    Seeing as there are so many phones, it can be hard to pinpoint the ones that’s right for you, so here are a few recommendations to take into consideration before you make your purchase.

    The Nokia Lumia phone line is a good place to start if you aren’t exactly sure what you want to have implemented in your smart phone. Every single smart phone these days has touch sensors (aka a touch screen), it’s a lot easier to manage than all of the buttons old phones had, as well as much more sleek and customisable. This allows for those who want to race through applications and games to do so with ease. The Lumia also sports a dual-core processor to make sure that it’s always running smoothly and correctly, which is just icing on the cake when it comes to it’s 4 inch AMOLED touch screen. This phone is not only incredibly functional, but it also has a great deal of personalisation and customisation within it’s programming.

    HTC also implements the windows operating system with its newer line of phones the “HTC Windows Phone 8x”. The phone itself is quite powerful, as the hardware within is more powerful than the Nokia Lumia. The phone also comes in multiple amounts of colours, allowing it to appeal to those who worry about the looks of their phones more than anything. It’s got different and not as well managed applications on it when you first use it (compared to the Nokia Lumia), but that doesn’t take away from the fact that it’s a powerful phone.

  • New Features Within Windows Tablets

    VivoTab Smart TabletSeeing as laptops are becoming more and more “obsolete”, tablets have found themselves on a pretty good track to glory. When you look around at people using their smart devices, you’ll notice that a lot of the people have switched from the traditional iPad to something a bit more unique. The new tablets that run on Windows 8 have tons of great and new things to learn and tackle within it, but what exactly are those things? We’re here to break it down for those who aren’t exactly sure, because it’s important to know these things!

    Snap multitasking is a great thing to consider when you’re talking about the use of tablets, as it allows for the user to run two apps side-by-side (as well as switch between them whenever they please). Some of the older tablets had problems running multiple programs/applications at once, so this is a great thing to have implemented into tablets nowadays.

    Another thing you should be looking at is the control panel itself, as it allows for a much more customised experience when you’re using your tablet. Windows 8 as developed to try and ease the use of tablets (as well as computers using Windows 8) for those who aren’t completely aware of how everything works. You can personalise your experience right down to the tee with the control panel, whether you’re changing up your background picture or simply setting up a wireless connection.

    As you can tell Microsoft has taken their time and really perfected their new operating systems to appeal to those who are on the go constantly. Mobile computing is the way of the future and Microsoft knows this, that’s why they’re doing their absolute best to create a great operating system for on the go. Windows 7 was great start, now we’re all the way to Windows 8.1 and people couldn’t be more happier about the fact. They’ve made incredibly vast amounts of improvement, so if you’re the kind of person who wants the best of the best for them when it comes to mobile computing, the newer Windows tablets could be a good place to start your journey.

    There are plenty of different types of tablets available as well, from the VivoTab Smart Tablet (which sports a 10.1 inch HD display as well as a 1.6GHz processors to smooth out mobile gaming), the Microsoft Surface Pro Tablet (which is the common one you’ll see being used, it sports the largest memory as well a dual-core processor). The one that gets overlooked quite often would be the Nokia Lumia phones, although they aren’t necessarily tablets they sport nearly the same look and use, just with additional features a phone would usually have.
