Install Ubuntu like a Windows program

By now you’ve heard of Linux and you will be struck. You can download it free, has hundreds of programs, number of fully configurable desktop interfaces, futuristic designs, y. .. zero virus. But the main question we ask is: Will I be able to install it? Will I lose my files from Windows?

At first, was very complicated to install Linux. The installation was done in command line with complicated orders only available to users. In addition, you had to partition your hard drive in the same way, losing your Windows installation at the lowest dismissal.

Today, the installation is easier and almost automaticBut there remains the danger of losing the Windows partition and our data. Fortunately, the latest version of Ubuntu brings a tool, Wubi, that will help us install Linux alongside Windows, keeping intact your hard drive.

In this article we will take steps to make possible an easy and safe.The first thing is to have our own record with Ubuntu. You can download it from Softonic and burn a CD with any recording program. Al put that disc in your CD / DVD, The following menu.

In our case choose Setup in Windows.

We can choose which drive to install Ubuntu, if you have multiple disks or partitions on your PC. Also available is the language, the amount of gigs reserved for Linux and a user name password to access Ubuntu.

Wubi creates a precise image on your computer to your CD of Ubuntu. When finished, it will tell you that it will reboot. When back on, see the following window:

From now on, every time you turn on your computer Windows will see this menu. So to you to use Windows or Linux. If you do nothing, Windows starts automatically. Where did you choose Linux, you’ll see your own menu, which also allows you to boot Linux or Windows.

The first time you start Ubuntu, it will finish installing. The process is automatic, so you just have to wait to finish.

That’s it. Now you have Ubuntu on your computer. What if you just like? If you try and think Ubuntu is not made for you, do not worry. Add / Remove Programs in Windows, you will see Ubuntu as a program you can uninstall without problems.

Comparison: file compressors B

Interface and usability

With all this, the most likely use of these programs is limited to unpack what the Internet and downloads a file compress sporadically. For this usually does not need to perform a thorough compression. That is compressed in a format that everyone can read, you serve.

Under this premise, all compressors are technically valid for a normal user. Compress, decompress, but are easy to use? Are they comfortable?

It is no secret that the popularity of the first WinZip and WinRAR later influenced the rest of the program interface. Both are virtually identical. The only difference is that WinZip incorporates some concepts that can be confusing. For example, "Favorites" and "Display." The idea of having it bookmarked folders containing ZIP files is somewhat bizarre, while the display option, which extracts and creates an entry in the start menu, no less so.

In summary, WinZip and WinRAR behave very similarly, but WinRAR is more to the point. The step by step wizard is another example. While in WinRAR options are clearly separate ("unzip", "create a new file", etc.) WinZIP’s assistant displayed more concepts ("favorite documents," "unzip and install", "WinZip Classic" …) that will produce doubts about alleged users without much knowledge of the subject, since they are using the wizard.

For its part, the interface is quite correct IZArc. No particular note, but it is easy to understand and use but have never tried the program. The basic options are at hand, the advanced menu. But it also has its shortcomings. For example, you can not browse the folders as it does in WinRAR and somehow, in WinZIP. Also, while doing a compression or decompression does not display additional information such as estimated time, speed, or percentage. Only a progress bar.

WinAce is not available in Spanish, which is itself an important fact. To this we can add the icons, old fashioned, not particularly easy to understand. But not all objections. It is the only program in addition to WinRAR which incorporates the concept of "presets", ie, that lets you record and re-use a specific configuration of compression.

7-Zip we have left for last because it is a kind of homage to minimalism. The buttons are not exactly art, but do not lead to error. This highlights enough when compared to the dialog box to create a file, which is really complex. Suddenly you are surrounded by words like LZMA compression techniques, dictionary size and block size compact, able to flee in terror for over one who "just wanted to compress a file." Okay, no big deal, but certainly not as friendly as other programs.

Conclusions

Compare these programs regardless of its price would be a crime and an injustice. Therefore, we have two groups of programs: free and commercial.

The free are designed for a different public. IZArc is more friendly for new users and is also the champion in terms of formats supported. It does not compress too much, but change is rapid. 7-Zip on the other hand is aimed at a more specialized audience that is willing to take the new 7z format for maximum compression.

Speaking of commercial alternatives, WinRAR is the most balanced. Very easy to use, with good support and some advanced, does not disappoint anyone. WinZip has yet to clarify their ideas and reorganize its interface, it seems that after years of development have been coupling functions haphazardly. WinAce for its part has fallen behind in several respects: it is slow, the ACE format is obsolete and does not always get good compression.

As always, we give you some clues, but the final choice is yours.

Value of 1 to 5 with 1 being the best value and 5 the worst. Is impossible to provide 100% reliable data, it is merely indicative.

Comparison: file compressors A

A few years ago when hard drives were less harsh and the Internet was less Internet, compression was vital. Some even remembered with nostalgia "? utilities such as DoubleSpace, compressing the entire contents of a disk to save space.

Today is no longer measured capacity in Gigabytes and Megabytes, but increasingly in Terabytes. The current Internet connections have nothing to do with the old, but has also increased the size of everything. Zillion-megapixel photos, games that take half your hard drive, programs that need more space than the operating system, enhanced documents which are to culminate in either enriched …

Overall, the compression is still necessary.

Then take a look at the most popular compression programs.

Compression formats

It’s no mystery that the extended format in Windows above all, is the ZIP. For a while RAR is gaining ground and, slowly but surely, beginning to be known 7Z. Each has its "home", which in this case is WinZip, WinRAR and 7-Zip, respectively.

WinAce ACE format added to the list, but this is very low ebb, in part precisely because the "special characteristics" of WinAce. As IZArc, is not particularly a friend of any form, although his name would appear that it is the ARC format, it is clear that not only decompresses files compressed in this area as little used today.

Programs compression / decompression are similar to other types of programs that support the more formats the better. It is very probable that never in your life you encounter a file. CPIO but what if …?

Here we must distinguish between the formats that compress and decompress. For example, it is more or less likely that we come across a compressed file with a strange area, but nevertheless will be very rare that we have the imperative need to compress into a different ZIP, RAR or 7Z.

As for decompression, which is able to open more than is IZArc types, including common formats and even some not so disk images ISO and NRG. The next would be 7-Zip, WinZip and WinAce followed by "does not open 7Z-and WinRar, open only 14 formats, but is all important.

Compressing none is capable of recording in three formats we’ve named. 7-Zip can handle 7z and RAR, and 7Z IZArc with ZIP, RAR and ZIP WinRAR and the rest only one. Anyway, this is not particularly relevant since all can be compressed in ZIP universal, which is as valid as others.

Speed and compression

The speed at which compresses and decompresses a file, the compression ratio and power are closely related equipment. In terms of compression, and we will not go into details, there are no miracles. A more thorough understanding requires much more time to compress and to decompress. So, you can not talk about speed of a particular program without also talking about compression.

This section is difficult to quantify because, according to the files that are compressed each format is better or worse performance. Still, there are guidelines more or less valid.

7-Zip and 7z can often get better compression, and not take you long.

WinRAR compressing RAR and WinZip, ZIP, have similar performance and balanced. WinZip can give a better result, but WinRAR is faster.

WinAce, except for isolated cases, does not get as good compression and what is worse, you need much more time for one task and sometimes with worse outcome.

IZArc, meanwhile, is quite fast, but the resulting file is compressed worse than others ..

What kind of maintenance does a solar heater? This type of solar water heaters do not have any mechanical or electrical operation, which makes equipment with minimal maintenance. Maintenance consists basically of two cosas.1. Clean evacuated tubes at least twice a year with a flannel soaked in white vinegar. This cleaning is done in the morning or afternoon 2. Change magnesium rod which includes the computer every two years.

What happens if you break a tube evacuated? If a tube is broken, this should be replaced with another. The kit includes a cap that is placed in the water heater to work while replacing the damaged pipe.

What size equipment do I need? In Mexico it is considered an average of 40 liters per person per day hot water, so we must multiply this number of gallons by the number of people living in the house where we installed the equipment and the recommended size. more computers are sold in the domestic market have capacities ranging from one hundred to two hundred liters.

Can you have installed solar water heater only without conventional backup system (boiler)? If it can, given the weather conditions of the Mexican Republic, and high levels of solar energy available in the country. The solar heater cover more than 85% of hot water demand in the year to ensure 100% consumption is recommended as a backup conventional boiler.

Do you adjust the hydraulic system of the house where the heater is installed solar? The installation is indoors does not change at all, will have solar-heated water at those points where it is normally. The only points where they adjust the hydraulic system are out of hot water boiler (if you have one) and the mains cold water tank is large (gravity systems).

Does the solar water heater works in winter? This type of solar water heaters, if they work in the winter and do not require additional fixtures to operate safely. The temperature of hot water delivered is 50 ° C, approximately around the country.

Does the solar water heater works on cloudy days? Depending on the intensity and the period of cloudy water equipment delivered hot to cold. If the cloud is partial, and lasts a few hours will have hot water, but if the cloud is severe and lasts for several days, will warm to cold water.

What is the proper orientation of solar water heater? In Mexico the equipment installed on the roof facing south geographic deviations of plus or minus 20 ° to the east or west are permissible. The average angle is 20 °.

What is the lifetime of the solar heater? This type of equipment has a lifespan of over 15 years

If you have not tried it yet, I strongly recommend it. It is often difficult to disentangle the many possibilities of more or less free programs that deal with audio files. Among the many I tried, a bit ‘out of necessity, a bit’ out of curiosity, very few have lived up to convert, cut and do all those operations required to professionally handle MP3, WAV and the rest. Professional programs are commercially available, expensive and often very complex to deal with this kind of files …

I do not doubt that its operation is flawless, what is certain is that if you search for a program that works well, it’s intuitive, small, and that performs all the operations commonly required by an average user, in this case are pain, because too often the audio cuts are not accurate, fade left to be desired, compatibility with files is not complete, and often it is difficult to import a simple mp3 because the frequency of registration that was not compatible and so on. And I could continue with the list.

For this Deluxe AudioEdit I was pleasantly surprised. The program is shareware, free download (with reduced functionality), and an activation key costs about forty dollars, with the change (and the actual currency) are little more than $ 29. Really nothing we can count on a product that works really well. Some difettuccio not deny it has certainly want to do the fussy, but in 5Mb of software and at that price, I’d say all in all we can get over it. But before we talk about the program and its merits, then I will make mention of small gaps.

First of all, we say that this software is an audio converter and an audio editor format: mp3, wav, wma, mp2, cd, ogg, vox, au, aiff, raw, cda. Therefore allows to manipulate the most important audio formats, after viewing the files via a graphical interface in the wave function, by applying filters of bandwidth, delay, amplification, fade, equalizer and much more, and supporting the possibility of two-way conversion between many of the formats quoted (mp3, wav, wma, mp2, cd, ogg). It also allows the creation and burning of CDs, and of course listen to the live audio files Treaty, through an integrated player. AudioEdit Deluxe is produced by Mystikmedia, now at version 5.0, an intuitive and simple interface clear and easy to use. Small flaws in software that presents, here are some:

1) a relatively slow elaboration of the file or changes.

2) If an amendment is carried, cutting files, fade, etc., especially in the files a bit ‘heavy, you should wait until the process is ended. If in the meantime, apply a new cut or edit, and you start will all slow down at times blocking the program.

3) the files can not be transported on the interface, not open that way. To open a file we will necessarily go to the menu (file-> open).

Problem aside, the program is a great tool if you do not have advanced needs, in which case better to turn to the most advanced software and demanding.

Is there any software for watching TV on our Apple hardware. It’s called Elgato’s EyeTV, and provides more than the hardware to the software solution that allows Terratec home to watch and record television programs broadcast on analogue TV, digital terrestrial or digital satellite …

The handicap that has always been recriminations and that, though, you can view only programs transmitted in the clear because of the lack of slots given to the insertion of the card for decoding. The only way to overcome this lack was the purchase of an Elgato EyeTV 310 that having an inside slot Common Interface (CI) has given the opportunity by the inclusion of a Common Access Module (known as CAM) use a card dedicated to the pay-TV digital satellite channels.

For the digital version of Earth is born today the model instead EyeTV 410. With this new model has been given the opportunity to enter a CAM that supports Freeview (so among those currently available for purchase in Italy we Smar CAM the Samsung CAM, etc..) In order to view digital terrestrial channels encoded (or as Mediaset Premium LA7).

Some major also been made for the satellite version, which uses the Sky with NDS Videoguard encryption and therefore does not currently viewable because of the use of a dedicated CAM within the decoder. To date, however, has launched a new solution that allows you to view encrypted digital and terrestrial channels to those in possession of a receiver without USB Common Interface slot. That’s right, the manufacturer Terratec, put on the market for the Terratec Cinergy CI USB MAC platform that is compatible with the EyeTV software allows the building “home” of a media center equipped with a Personal Video Recorder (PVR) on a Mac

How to create slideshows with Memories On TV A

Before digital photography, few privileged people who have the resources sufficient to create photo slideshows. It was necessary to develop the pictures, scan them, mount them with a table editor and save the result as an analog system.

Now, anyone can become a professional video composition. Just take a digital camera and a home PC to create, in minutes, stunning digital photo slideshows.

In this tutorial we show you how you can make your own slideshows using MemoriesOnTV, a very user-friendly program with that achieved with minimal effort, great results.

What do we need?

For starters, we only need the program MemoriesOnTV installed in our system and a folder with photos you want to use in the composition.

MemoriesOnTV environment

The program environment is divided into three basic parts. The manager of albums (1), the work area (2) and a third zone with multiple functions (3): file explorer, audio editor, manager transitions or effects, menu editor and manager of recording.

Step 1 – Import Photos

The first step is to import the photos that we use in our composition. Just sign in a folder, select and drag images to the workspace.

Step 2 – Customize the sequence

Once imported photos, we can arrange them want to crawl over one another and customize each image from the "Set Slide" from the context menu (right mouse button).

In this window you can add decorative frames to include all types of masks, change the levels of the image, rotate, resize and even add text.

Step 3 – Add background music

To select the soundtrack of our membership, we changed the light "Music" in the third area of the environment, click the sign window and select the song.

On top of this area, we see the expected time of the video and song length. From the pop- we can synchronize the video with the music, add areas of silence or cutting songs manually.

Although it seems contradictory, can be generated from cold to heat. This is very attractive as it is in summer when cooling demand is greater and greater availability of solar energy is presented.

It is possible to cool a home with the same installation of radiant floor warming in winter. For heating water is passed hot and cold water to cool. That is not all, because in summer need to dehumidify the air. This will have to install a dehumidifier Fan-Coils.

The absorption machine

The absorption machine was invented in 1859 and the operating system is very similar to a refrigerator or heat pump. Basically, the mechanical compressor is replaced by a thermal evaporation and absorption, leaving as the refrigerant circuit. Attaching an absorption refrigerator for a solar heating system would be achieved, in addition to hot water and heating in winter, hot water and cooling in summer. But this option has some drawbacks.

The technology can harness the heat absorption of fluid 70 – 95 ° C to generate cold, showing a coefficient of performance COP strongly linked to temperature. The COP between 0.7 i 1.4 according to the temperature of the hot fluid is in the upper or lower limit.

Solar collectors, to depend on the sun, can not guarantee a constant supply of hot water at the desired temperature. To ensure the required cooling capacity of a home, you need to oversize the absorption unit and installed a backup boiler to heat the hot fluid when it reaches the desired temperature.

The solar collectors of vacuum tubes are best suited to achieve an optimum temperature for the operation of the facility, but much more expensive than flat receivers. The cost of an absorption machine is already high in itself. This will have to join them the facility and its components and the fuel consumption of up heater.

In addition, the installation requires a cooling tower, a controversial element currently being bed Legionella culture and needs constant maintenance and a special location. All this makes the use of this system is not the best way of cooling using renewable energy to be wasteful, with a high initial investment, and have the need for constant maintenance.

The alternative

The air conditioning or heat pump get better conventional COP coefficient of performance, about 3.5 4.5, so that energy savings is much higher. In addition, the investment and maintenance cost is lower, and its technology more widespread in the market.

To function consume electrical energy that can occur in a clean and free of charge with solar panels. These are well suited as in summer, when there is more need for cooling, can generate more energy because there are more hours of sunshine.

The cost of a photovoltaic system also is subsidized by the state and can connect to install a network to sell electricity and make a profit, before amortization of investment. Using the same source, the sun, this system achieves better performance with easier installation, maintenance free and a much smaller initial investment.

If you want cool in summer and heating in winter, it is advisable to install a heat pump with underfloor heating and dehumidifiers.
