Our prices are very flexible. In fact, you can pay for checking any of your websites from as low as EUR 0.3 / ping / month. Note that you can set up monitoring with intervals from 1 minute to 2 hours. Since you pay for only consumed resources, you can easily name your own price.
CMS is a short term for Content Management System. Probably the best known system, with the larges audience and largest pool of developers is Wordpress, which was developed in 2004. Used as a tool for simple blogs, this platform currently serves more than 20% of internet traffic. This platform was open for all developers, who could easily add new plugins, addons and another usefull extensions. Nowadays, it can easily serve you as a primary platform for your ecommerce store, company website, or old-fashion blog as well. Another bonus is that this system is free to install, released under open-source licence, so you can use it, edit it, change it as you like.
Our server technology uses different locations worldwide, that can give you the best possible information about your server uptime from various locations. Monitoring from just one location has one big pitfall - even ideally created monitoring software is not able to discover network problems on the way to the monitored site, so it may put many false alarms to you as a client, even if your website is 100% available to 99% of world population, the only network of monitoring server is offline. That's why I-monitor.xyz gives you 100% non-false alarms by monitoring your website from 10 different locations worldwide. If your site is offline for at least 3 nodes, then we consider your site as unavailable and send you an alert.

The Linux office is not just LibreOffice. Relatively interesting is also the OnlyOffice package, which recently released source codes. The software is user-friendly, but the impression spoils various unfinished functions.
You may not have heard of the OnlyOffice office suite developed by Ascensio System. And there is no wonder. OnlyOffice focuses mainly on corporate clients that offer a product as Microsoft Office as free as LibreOffice. At least so boldly present the official site of the project.
OnlyOffice offers classic desktop applications, mobile apps, and web editors. Only desktop applications are available freely and we will be the ones in this article. You do not need a subscription or any account. Just desktop applications have been newly released as open source, but otherwise they are available for a long time. They support Linux, Windows and MacOS.
Alternative office packages are often LibreOffice or OpenOffice, but this is not the case. OnlyOffice is software created from scratch. While of course it is possible that some pieces of free projects were used.
As far as Linux support is concerned, it is at a very good level. DEB and RPM packages are available for many distribution versions (including the older Ubuntu 12.04) and adders can also add repositories for updates. For other distributions, a universal installer is available. All this is only for 64-bit systems. The Windows XP and Vista support, which many other programs have already written off, is also very impressive.
The first impression will be the fact that even though OnlyOffice manages to work with text files, spreadsheets and presentations, all this is served by one single application. This would not be as interesting in itself, but OnlyOffice open files rank in cards similar to a web browser. This means that you have only one window and many cards in it - you can also have documents, spreadsheets and presentations at the same time. Personally, I like it very much. However, there are also users with the opposite view, who will not be pleased that the official option to display documents in separate windows does not exist.
As for the speed of the program, I have no fundamental objections. You almost do not expect anything and the interface response is satisfactory, if not perfect. The speed of switching between cards is lightning-fast. This is related to the use of memory, where it is a bit worse. If you only have a text document editor open, OnlyOffice will take around 150 MB. However, if you use the modules for spreadsheets and presentations, you can get up to 500 MB altogether. In this respect, LibreOffice is much better off. When used similarly, the memory consumption is between 50-120 MB.
OnlyOffice although not speak many local languages, but at least it is available to control the local spelling, resulting in a narrower offer about thirty languages which is ok, I think. However, there is a lack of support for local data and currency formats, which limits serious use in the other, than english environment, for example in companies.
Is OnlyOffice really capable as Microsoft Office and free as LibreOffice? It is not. It has far as many functions as none of them. I would say roughly a quarter of the possibilities of this competition. At the same time, it is more capable than Google Docs. Ask yourself how many LibreOffice options you actually use. If you do not write a diploma thesis or something similar, OnlyOffice will probably give you everything you need.
As for the interface, we are somewhere in the middle. This time between Microsoft Office with Ribbon and LibreOffice. All the options are constantly in your eyes, and when you click, you get the option to choose exactly what you want. However, long and multi-level quotes are not available. It is seldom likely that a feature menu opens in a separate window. This is only the case where it is really needed - for example, with the graph insertion guide.
Together it is used very well. Setup and formatting is very fast, as there is no need to search for extensive offers. I have to say that the authors have done well to hit what users need and what is most unnecessary for most of them. In use, I found only one option that I missed more, namely the ability to select my own colours for individual graph elements.
Nowadays, when most mobile application software is created and distributed on a continuous basis, it is also necessary to ensure ongoing automation of mobile software testing throughout the world. With Android and iOS mobile applications, it is a problem to test for a huge number of HW variants, display sizes, editions of operating systems from different manufacturers in different parts of the world on real devices. Simulators and emulators are mostly not the right ones. If I'm already testing how to make my own beta distribution a true real tester across platforms?
Let's quickly introduce one of the world's most used services for this purpose. These are Xamarin Test Cloud and HockeyApp. Both services are highly independent of development technologies and platforms, but have recently been purchased by Microsoft, the latest developer and tester of Android and iOS applications. Both services will be part of the upcoming integrated multiplatform DevOps service of Microsoft Visual Studio Mobile Center.
Xamarin Test Cloud is a remote cloud service for testing mobile applications on real devices. It's actually a server room full of physical Android and iOS devices and utilities. It is designed for massive execution of automated UI tests on many different types of devices. It is independent of Xamarin technology, you can test applications written in virtually all types of technologies, run them manually, or use any instrument below for the CI / CD orchestration.
At the beginning of the process, you need to create a universal automated test, which then multiplies, triggers and checks, and reports clearly. You can use the Xamarin UI Test, Calabasch (Rubby) or the Appium Framework to create UI test scripting. But I certainly recommend testing the new Xamarin Test Recoder for Visual Studio or iOS - it will greatly save your work with testing because it generates what you do on a physical device or a simulator.
Xamarin Test Cloud supports gestures, major physical phone sensors such as GPS, buttons, camera, rotation, etc. After performing tests, you get very clear overall reports with details on the device.
At present, two Xamarin Cloud Tests are actually working. The newly upgraded version is already part of a larger package - Microsoft VS Mobile Center. You can try both in free trial mode.
In most cases, it is not enough to test applications on a large number of different physical devices. The app should also be continuously provided to a limited number of specific people who already have their own phones and tablets. From them, collect real bugs and analyse potential crashes, ideally also get feedback from real use by the tester. Yes, virtually all public beta distribution stores have, but everyone else and interactions with beta testers are not well secured. Here is HockeyApp.
The goal of HockeyApp is to ensure simple and continuous beta distribution of new versions, collection of usage information, and the ability to interact with the beta team with the development team. If the application is already final, there is also a unified collection of user metrics and telemetry across platforms. In general, this is a very important part of Mobile DevOps workflow.
Unlike UI testing, there is more to go into the code - to be able to insert the instrumentation for data collection. This is done by client SDKs, which are publicly available including source codes, and even for Unity.
Beta distribution does not go into different public application stores, but first into a unified private application point for testers, where all platforms and applications are together, all are configured, co-operative, reporting, etc. Tester's online application, they also have additional functionality available, for example, to send feedback to the dev team from the application. The development portal contains different types of reports on user and application behaviour. HockeyApp can be used or tested for free in a free single user plan.
As mentioned above, both of the above services will also be part of the upcoming mobile DevOps package in Visual Studio Mobile Center.
This cloud service is now available as a preview, on-demand, and covers the entire lifecycle of mobile applications. In its current form, it offers the following services:
All the features are, you can use the REST API in addition to the web interface. Read the documentation.

Intel and AMD have been duking it out for nearly 30 years now in the computer processor ring, but who is truly the champ? Let's take a look.
The heart of a computer is the central processing unit, also called a microprocessor. In simplest terms, it is a set of computer registers that loads data, reads instructions from memory called a 'program', and performs a mathematical operation on that data according to the instruction. It then proceeds to the next instruction, processes the next load of data, and so on.
Since its inception, the microprocessor has blossomed into a massive cluster of these operators, processing much larger loads of data and running at blinding fast clock speeds, allowing billions of these instructions to take place every second.
In spite of the advancements in speed, programs were written that challenged the capabilities of the processors. To increase their capability, processors were designed with more than one 'brain' and multiple sets of registers, with each clicking through instructions simultaneously. The increase in speed was phenomenal. A programmer could write software to take advantage of this capability and process massive amounts of instructions and data in a much shorter amount of time. Each of these is called a 'core', so the more cores that a processor contains the more powerful they are.
As the two powerhouse developers of microprocessors, AMD and Intel have both continued to advance the technology to breathtaking levels. Each company sometimes focuses on a specific spectrum of processing capability with certain chips, and it's important to choose accordingly.
Although dual-core and quad-core devices took computing to new heights, they quickly gave way to newer generations of chips with eight, twelve or even more core. The current offerings by both companies boast 16-core processing power, unheard of before now.
To take advantage of these powerful features, both the operating system and the added applications must be engineered to utilize the multi-core capabilities of the processors. Since the design of the Intel and the AMD versions are somewhat unique, a software engineer may construct his program with a particular chip configuration in mind, making that software better for the specified processor.
As a result, many applications will explicitly state that they are optimized for a particular make or model of processor. To achieve the best results, they recommend that your hardware match their design. Thus, the success of AMD and Intel in the industry is often led by the software companies, who prefer one processor over another.
The two most demanding areas of computer programming in terms of processing power are business applications and gaming. These two areas have vastly different requirements for processing capability and will be tuned to the chips that have the power that they need. Gaming machines process massive amounts of graphics in full motion animations, whereas business software demands the manipulation of huge quantities of data to multiple users simultaneously.
Probably the most significant difference in the AMD and Intel offerings is the price. Intel is still considered the industry leader to many, and the cost remains high, where AMD may produce chips with more features but still maintain a low price point. Both processors remain extremely popular.
Server hosting services are ideal for situations where a company may not have sufficient capital to put up the necessary infrastructure. The burden of routine infrastructure is also taken off the company's shoulders as the hosting company does it. The company can then focus on their business and not worry about buying, setting up, and maintaining the server hardware. There are different types of hosting services, that is, shared, dedicated, and VPS. If you are on the lookout for server hosting services, we discuss the 10 best companies you should consider.

Hosting your own software application can be a daunting and demanding process, and deciding whether to invest in your own server, or to contract space on a commercial host, adds to the complications. There are advantages and disadvantages to each.
There is no doubt that the up-front costs of owning your own server are high. Servers are some of the most powerful hardware and software platforms in the world, and they don't come cheap. The various components, from power supply to motherboard to drive arrays are state-of-the-art for performance and efficiency. Even a simple local file server requires a powerful hardware platform to produce acceptable results. Skimping on quality or capability is simply not an option - for a properly designed server you must go all out and acquire the best.
Offsetting the up-front cost, however, is the long-term savings. Once your system is in place, you no longer have recurring fees for your hardware like you would with a hosted system. These savings can be substantial, and may actually be more economical in the long run depending on the other costs of operation that you will encounter such as repairs, maintenance, and upgrades.
One serious disadvantage of owning your server is the cost of upgrading as technology advances. Nothing changes as quickly as computer technology, and server hardware is an integral part of that entire system. As software advances by leaps and bounds daily, so also the hardware platform that it runs on must grow. Keeping up with the ever-changing market can be inconvenient and costly. Since you own your server, every upgrade comes down to you and your budget. If you pay a provider to host your application, they would contractually provide all upgrades as a part of the service. It's a trade-off that must be considered carefully before deciding which way is best for you.
Another serious factor of retaining your own server is downtime for repairs and maintenance. Nothing frustrates users and customers more than software that isn't working, whether it's a dedicated application, an informational website, or an e-commerce site. Downtimes cost you money and must be limited as much as possible.
Most server owners understand the need for backup components as well as a sufficient software backup solution. If a component of your hardware fails, you need to have replacements on-hand or within immediate availability, which usually adds to the costs of ownership. The sooner you can replace the failed units and get your server back in operation, the better you can survive the downtime. A hosting provider is typically prepared for failures and often boast about the very short downtimes they experience, giving you more opportunity to remain online. Again, careful consideration of the two options is critical.
The bottom line is, both owning your server and hiring a hosting provider have many advantages and disadvantages. Evaluating your technical capabilities, budget and time investment can help you make the right choice for you and your enterprise. Whether choosing the higher up-front costs and ongoing maintenance requirements of server ownership, or the long-term expense and lower time commitment of a hosting provider, your choice will be an important one for your business. Choose wisely!
Your choice of server host can have a big impact on the impression your website makes on visitors, an impression that's doubly important when those visitors are prospective clients or customers. Here are 10 key traits to look for when seeking a quality server hosting company.
It pays to have a web host who can guarantee your site is live whenever someone tries to access it. Reliable up time increases visitor trust and confidence in your brand identity.
A quality server hosting company avoids overloading its servers and ensures that hosted sites have swift load times. Speed means convenience, and ensures longer stays and more return visits from readers.
Once you've decided what kind of server host you need -- dedicated for large commercial sites, virtual private server or shared hosting for smaller sites -- ensure it provides the storage you need and room to grow. Having ample storage allows you to design your site with maximum freedom.
When a company says it offers "unlimited bandwidth," what they usually mean is that they don't restrict the amount of data that can be transferred to and from your site at any given time. A quality server hosting company will be transparent about the concrete meaning of this claim. Practically speaking, there may be "hidden" restrictions imposed by the nature of their hardware, or the policies of your internet provider. This is a complicated issue worth delving into in detail, and you can find more information here.
If something ever does go wrong with your service, it's crucial to have support from your server host. The best companies will have a reputation for friendly and helpful service and expert tech support.
A quality server hosting company provides powerful tools for designing your site, managing its content and tracking performance and visitor statistics.
Look for a company that's willing to stand by its services. Many hosting companies offer money-back guarantees within a certain timeframe, to ensure that you're satisfied with their results.
Just as important as a site's performance is the security of your content. A quality server hosting company provides regular backups to ensure that your data is not lost if a security breach or other unforeseen event occurs.
Apart from backups, a high standard for server hosting demands a suite of other security measures: virus and malware defenses, protection against DDoS attacks, firewalls, password access and user management, and thought-out disaster recovery plans are all key features to look for.
Once all the basic requirements of a quality server hosting company have been met, then of course you'll also want to go with the option that's easiest on your pocketbook. Just ensure that you're not being asked to trade off high standards for a lower price.
Deciding on the right hosting service can be complicated, but it's worth taking time to research and check that prospects show these 10 key signs. They'll ensure that you're setting your website up for success with a quality server hosting company.
Twice every year (in June and November) since 1986, TOP500, an organization that uses High Performance Linpack or HPL to track the fastest computers, has released a ranking of the most powerful machines in the world.

The history of Dell dates back to 1984 when Michael Dell was just 19 years old. It was a startup with just $1000 and there was a change in the vision of technology industry. It was a matter of 4 years and Dell went public in 1984. The market capitalization of Dell at that time was $85 million. It is amazing that in such a short span of time Dell was able to achieve so much. It is like an inspiration to many startups out there seeking to develop a name in the market.
In 1992, Michael Dell became the youngest CEO of Fortune 500. He started at the age of 19 and before hitting 30 he was famous among the businessperson of Fortune 500.
In 1996, Dell.com was launched at the website. At that time, the sales were $1 million per day. This remarkable result was obvious after six months the site was live.
In 2001, there was a distribution deal between Dell and EMC. The purpose of the deal was to get more enterprise, which is affordable.
In 2005, Dell was a part of America's most admired companies in the Fortune Magazine. In fact, Dell topped the list.
In 2010, Newsweek regarded Dell as the greenest company in America.
In 2014, the company was removed from the list of Fortune 500. The company stopped making the figure of official earnings visible to the public and went private.
Dell Products are available at various outlets. The products are common among the masses, however; there is an increasing competition in the industry over the years. Michael Dell had left the position as CEO in 2004 but later rejoined in 2007.
There is a Dell Family home, which is the 15th largest in the world. It is in Austin. It comprises of 21 bathrooms and 8 bedrooms. It also has a gym and a conference room.
In terms of the market share, Dell was ranked as the third in the world in 2017.
There was a focus on e-commerce and social media marketing by Dell in 2010.
It is amazing how the world works. What is prominent today might be just a part of history in the next few years. There is a cutthroat competition between the companies belonging to the age of modernization and information technology. They strive to survive and have to take all the measures in order to remain in the sight of customers as they say in marketing, "Out of sight is out of mind." Dell seems to have an amazing history, which can serve as a source of inspiration for many entrepreneurs.
Cryptocurrency is a phenomenon, being a digital form of money costing lots of real-world money, with Bitcoin being the reigning champion. Bitcoin is "mined" by using software to solve complex equations, rewarding the lucky miner with a bitcoin each time the problem is eventually solved. Why? The fact that since 2014 Bitcoin has grown from an exchange rate of 1 Bitcoin to $1, to 1 Bitcoin being the equivalent of well over $5000, is enough to interest anyone. In late 2017, 1 Bitcoin fetched literally as much as $15,000!
But how does this relate to hardware prices? The calculations used in mining these Bitcoins requires some pretty hefty processing power to also be carried out at a worthwhile pace (a long time, these days). A computer's central processing unit (CPU) is primarily used in computing, gaming or otherwise, to work things out and solve algorithms. However recently, dedicated graphics processing units (GPU) are also used to massively increase a machine's processing power, and this is where the problem lies.
Hardcore miners will buy GPUs in bulk, setting up literal farms of them to run these Bitcoin-generating calculations endlessly. The more problems they solve, the more real money they can make, sounds easy right?
When these miners buy their multiple GPUs, they then deplete the stock of retailers at a highly accelerated rate. This leads to the recent exorbitant price hikes. It's also worth noting that high-end GPUs aren't exactly particularly affordable at their standard price anyway. For example, if you look at the price of a Nvidia GTX 1070 in early 2017, it cost just shy of £300. Today, you could actually sell it for around £550, due to these now inflated prices.
Because of this, it is currently a pretty bad time to buy or upgrade your PC's GPU, all because of people buying hardware designed for playing video games — and not using it for gaming. It's kinda sad to see this happening, but it was pretty expected. For reference, the mere prospect of moving from console gaming to PC gaming is pretty daunting the best of times, due to the extra complication of installing all those individual hardware components and of course, the often-higher price. Price hikes like this only deter consumers making the leap to PC.
Many people expect the success of Bitcoin to be just a 'bubble', which is going to burst anytime soon (though keep in mind people have been saying this for years now). With any luck, Bitcoin and this cryptocurrency craze will fade away and GPU prices should return to a more affordable position for regular consumers.
In recent months several millions of dollars of Bitcoin have been hacked and stolen in an instant, which should hopefully prohibit cryptocurrencies from getting much bigger by deterring wannabe miners from getting involved in the whole Bitcoin business in the first place.
Memcached is a high performance free and open source distributed memory object that is used for speeding up website applications by improving database load. It is used for small arbitrary information storage mainly from results of page rendering, database calls, and API calls. Also, it enhances quick deployment of data and a problem-solving tool. This caching system is popular and reduces the number of times an API is read, more importance includes.
Least Recently Used (LRU): It determines when to delete the recently used or old data or reprocess memory. Additionally, it has a client-based hashing algorithm, Memcached has a key that enables this algorithm to choose a server – this helps distribute the load. Furthermore, it is composed of a Client Software tool that is given a whole list of available Memcached servers. Also, it has a managed Server Software that stores numbers and their keys into an internal hash table.
The four main components mentioned above work together to achieve data storage and retrieval, on a high level, this tool works in three important steps. Firstly, the client logs in and demands a piece of information which is checked by Memcached if it is available in the store. Secondly, if the requested information is available in the cache, the program automatically produces it, but if it is unavailable, one is required to query the database and get the data and subsequently store it in Memcached for future reference. Thirdly, Memcached is programmed to automatically update its cache by removing the expired values making sure the contents available are fresh. Notably, Memcached ensures that servers don't share information and that data is only sent to one server.
Firstly, this server is used when loading information, the process has few steps such as execution of queries to load the information from the database and change the information so that it is suitable for display and further processing, and finally using the information or just displaying it. One is always required to change the application logic in order to put up with the cache. The process of changing the logic involves loading the information from the cache and if the data is available, use the cached version of the data. However, this tool allows you to execute queries when the information needed does not exist and subsequently formatting the data for display and storage as appropriate. Additionally, Memcached allows a user to update or store information in a characteristic app. The updating process follows a procedure which starts by updating the category list in the database, then formatting the data, storing the new data into Memcached and later send the updated data to the client. The tool ensures that when a client lays his/her hands on information that many people use, it automatically gets added to the cache list and any new changes are immediately updated.
Furthermore, Memcached is useful when caching relatively small data like HTML codes, this is because the memory of Memcached utilizes fewer memory resources for metadata. Also, it has Stings, a data type that is supported by Memcached, Strings are good for storing information that is only read since it does not need further analysis. Equally important, Memcached is multithreaded a feature that allows a user to scale up by giving it more computational resources. The only disadvantage about the multidimensional feature is that some data might be lost in the process since it does not perform clustering.
Developing an application using an Integrated Development Environment (IDE) makes work easier and offers a ton of handy features that makes the process fun. If you are a node.js developer or wish to be one, and would like to create your web applications on a Linux computer, there are quite a number of great IDEs to choose from. Most offer such features as auto-complete for tags, class prediction, plugins for extended functionalities, and pre-made snippets of code by default. Here is a list of the 5 most popular that you should consider.
Sublime Text is the best IDE for Linux hands down, no matter what language you are developing your application on. This feature-rich IDE is also the lightest of all and is most popular among professional node.js programmers. Some of its top features include Minimap, a zoomed-out view of the entire file that acts as a visual scrollbar, a range of pre-set and customizable keyboard shortcuts, a powerful multi-select feature, and personalized snippets tool. There are of course a lot more features that you better discover on your own by setting it up on your system.
Developed and maintained by Adobe developers, Brackets has been popularized by web developers and offers a lot of support for newbies into the node.js platform. This IDE offers a number of several awesome features that make it stand out as the right one to learn node.js. These include support for plugins that offer extended functionalities, easy installation of plugins, in-line editing, and live preview of the code. With such a broad development support, Adobe has made Brackets a popular IDE for web development and plugin creators.
Atom IDE was developed by Github and is one of the few fully hackable environments that advanced developers can customize to suit their needs. One tactic that most node.js developers use to get ahead with this IDE is to find an already-hacked version of Atom personalized for node.js. Atom's development environment takes care of most things that a developer would want included in the development environment by default including auto-complete, browser inspection element, and full Github integration and support. It also features Markdown syntax that supports live browser preview.
Originally created for Kubuntu, KATE is a text editor based on Ubuntu Linux that offers lesser functionality and features compared with the rest of the tools on this list. This is an ideal IDE for you if you are looking for something lightweight that supports multiple open sessions and powerful features for a specific language such as node.js. KATE offers the standard IDE features such as auto-completion, automatic indentation, syntax highlighting, and bracket matching. It comes with an embedded terminal, SQL plugin support, and unexpected shutdown recovery features.
If you are looking for the best IDE for node.js for Linux, these five tools are the best place to start your search. Eventually, you will figure out which IDE best suits your needs development needs based on your programming etiquette and preferences.
When it comes to operating systems, everyone knows who the top two are - Apple's Mac OS and Microsoft's Windows OS. While Linux is a third system many are aware of, its popularity is limited primarily to hackers, developers, and computer geeks in general.
Why do software, app, and tool developers seem to love it so much? Here are a few reasons.
Mac and Windows operating systems share one major characteristic - anyone who wants to use them has to pay for them. Linux, on the other hand, is available on multiple websites and can be downloaded for free. All it costs is the time spent on an internet search and waiting for the download to finish.
This does not only apply to the operating system, though. Tools and software for Linux are free (or extremely budget-friendly), while the same things cost money for other operating systems. Developers loves this because they can test out ideas without depleting their bank accounts.
The Linux OS is Free and Open source, and source code is readily available to system users. It is also structured in layers, which makes it easy to configure the system more specifically for the tasks it is being used to complete. If a developer does not like the way something about the system is working, they have the freedom and ability to play around with it until it runs exactly the way they want it to.
Developers are trying to accomplish some big tasks with their work, and the last thing they have time for is their computer's memory to be eaten up while their newest project is compiling. The Linux OS uses far less memory to accomplish similar tasks to its Mac and Windows counterparts, so their systems run faster and they can get more done.
Both Windows and Mac OSs are known to collect massive amounts of information from their users, even if they are trying to anonymize the date in transmission. Linus systems are better able to protect a user's information because they collect very little of it (if any) in the first place. Developers like this because it lets them protect their personal information and their work.
Some of this can be attributed to the overall tech savviness of users the Linux OS attracts, but this is true for other reasons as well. Users have to have full execution privileges before they can open attachments. This makes it more difficult for threats to get through to the system in the first place, which is important to developers because it helps keep their system safe.
