In OnSoftware we have made our list of 10 that we find most useful.

FastestTube

Download videos from YouTube will never be a problem, this extension seamlessly integrates video downloads on the page of Youtube.

Download Helper

Speaking of downloads … Do you often use sites like RapidShare and MegaUpload? If so, this extension will avoid having to keep track of countdowns, and other aid for a better download experience.

Translate

Translate translation option mimics the Google Toolbar and Google Chrome: when it detects that a page is written in a language different from yours, gives you the option to translate. It works great, although it should set it to not be advising all the time.

Weather Forecast

Are you one of those people who need to stay informed about weather conditions around the clock, Weather Forecast is for you, it adds a small button with which to consult Yahoo! prediction

Facebook Chat

Using Facebook Chat can be relatively Facebook chat by hand, from a button on the toolbar. Now, to see what goes on between your friends should use Facebook , an extension to load the mobile version in a floating window.

Panic Button

Of course, if you get to visit Facebook at work, your boss probably will not make too much grace. To avoid prying eyes have Panic Button, a button that hides all your open tabs as it pulses. Remember to restart your browser after installing and beware of data loss, because the tabs are really close.

Gmail Checker

To be always aware of when you receive an email in your Gmail account there is nothing like a notifier. They come in all flavors and tastes and, of course, also as an extension of Opera.

BugMeNot

Today most of the pages they ask you to register to do anything. And if you’re just passing through? To do this you can use BugMeNot, a kind of database with usernames and passwords for multiple pages. The result is not always satisfactory, but try to not be …

Firebug Lite

If you are a web designer, probably at fault throw the fantastic Firefox extension, Firebug, which has already been ported to other browsers and is also available in Opera, however, in Lite version.

AdSweep

Extensions to block advertisements are always positioned among the most popular. Opera at the moment, there are two that stand out: AdSweep and NoAds . The latter does not seem to function properly in newer versions, so we opted for AdSweep. He still has much room for improvement, but does its job (at least in part).

Do you know and use some extension for Opera name worth?

Connect your PC to TV 8

07 Mar

Connect your PC to TV

Thanks to the media player programs, such as boxing, which we have devoted a series of tutorials , the computer has become the center of the home audiovisual entertainment. So it’s time for the TV again claim his throne …

In this article we will teach you how to connect your desktop or laptop to the TV , to take all your content into the living room of your home and enjoy them with yours.

We will take as a reference for our tutorial laptops, and portability issues that are often connected to television. However, the advice they give you apply to a desktop computer or a mini, since they have almost always with the same outputs for video and audio.

Inputs and outputs

As recently to try a similar case when connecting a laptop to a monitor to make it our main screen, you just refresh my memory: the first and most important element you have to check is the video input and output for equipment and television respectively.

In some cases, a cable with appropriate ends will suffice to carry the signal to the television team, in others also need a converter to reach its destination correctly.

First let’s see what are the most common video outputs :

S-Video

Also known as Y / C , is a connection standard that carries a double signal: luminance and chrominance. It is very common on all televisions and computers, and requires very little outlay, a single cable male / male for the video signal , and a dual RCA (the typical red and white) for audio. Its image quality and resolution have become obsolete TVs in the last ten years.

VGA / MiniVGA

This standard connection as both screen resolution appeared in 1988 but remains in effect today in certain areas. In televisions, which is what interests us is insufficient for HD monitors but it for the rest. MiniVGA version has the same characteristics, but the socket was reduced to optimize the mobile space.

DVI

It was the first standard analog video interface and no, although not as widespread, best meets the task of sending the signal or TFT monitors, as is the case, a digital television screens. The main advantage of this connection is available in three variants to suit all types of TVs: DVI-A , which sends an analog signal such as VGA, DVI-D , which does the same with the digital signal and DVI-I , sending both simultaneously. The latter is what usually comes with integrated graphics cards laptops , allowing you to connect to a TV signal without digital input via DVI to VGA adapter.

HDMI

One of the newest and fast connections to be implemented, and has become the de facto standard today for HDTVs . Improvement over pre-integrated into a single signal cable video and audio, and makes it easier than ever to connect your laptop to the TV. However, only Full HD televisions can benefit from increased image quality offered , and only the most recent notebooks have integrated the series.

DisplayPort

Emerged in 2006 by agreement of the VESA (Video Electronics Standards Association), this connector lives as competition, while in addition, the HDMI standard. Like the latter, carried simultaneously the image signal and sound , and has grown more in the field of computers on their televisions. As a bonus, mention that there is a smaller version called the Mini DisplayPort , which is listed as the only video output possible for all MacBook and MacBook Pro, iMacs and the Apple brand.

Regarding the input connections , as well as the aforementioned video outputs, there are some more typical of TV formats that are still used

Composite Video

One of the oldest video connections, which offers a rather poor quality in LCD TVs , but is still used in cathode ray tube televisions, ie in the older analog displays. Many know him as the head yellow cable into the cluster of three RCA, which also includes white and red for audio.

Component Video

Some TV models had advanced analog connection that the only composite video cable. In this case, the video signal comes through three wires red, green and blue, carrying different combinations of luminance and chrominance in order to show better picture quality. There are two variants of signal: RGB and YUV, but both have the same input on the TV .

SCART

Better known by all as the cable scart , is standard on all televisions in nearly twenty years. in the same cable carries the audio and video signal , but it has become obsolete for its low resolution, in favor of other formats such as HDMI. As a curiosity, it was a standard imposed by law in their country of origin, France, but ended up spreading even in the Asian market.

Connections

Having said all that, we could be speaking about the possible combinations of cables, adapters and signal converters to cover all types of inputs and outputs. However, for convenience, we have prepared a table annexed that collects and proposes solutions simpler and easier to find. In this table we have considered the cases worth pointing out, ruling in turn those who lose too much video quality.

The solutions we offer are divided into three categories: straight-through cables , such as those carrying the signal between outputs and inputs of the same type of signal adapters that convert between different types, sometimes with some loss of quality by the way and finally, by processing converters , which usually take the form of signal coding. The peculiarity of the latter is that they require signal processing by completing and comprehensive reporting to comply with the requirements of the input format of TV. This happens, for example, when you want to convert an S-Video signal to VGA .

In some cases, the connection between formats is not simple and requires several steps , ie converting the first signal format and use another adapter to convert it to a third party. Should know that these conversions tend to lose quality , so you have to avoid unless absolutely necessary.

Click the image to view larger

All solutions presented here can be found at electronics stores, both traditional stores and online. There are many cables and adapters brands, making it difficult to opt for one, but yes, always seek to offer a minimum guarantee of use.

We hope that with this information you may have clear process to connect your laptop or desktop computer to the TV and enjoy movies or series in the comfort of your couch, either Boxee or any other player application.

All you need to know about the digital certificate

All you need to know about the digital certificate

One of the problems of using online services is the lack of security means both to protect the transfer of data to ensure the identity of the user. For these reasons, it launched the concept of digital certificates. A system that allows electronic data link with individuals through a certification.

The aim of this paper is to answer questions like: What is a digital certificate? What is? How it works o How to get your own certificate? So if you want to shed some light on these questions, read on …

What is a digital certificate?

A digital certificate is a document issued by a certification authority that guarantees the association of an individual with a digital signature.

What is?

Basically, the digital certificate is the mechanism that allows us to obtain a valid digital signature to sign documents electronically. Depending on your level of security, digital signature provides the same guarantees as the holographic signature and ensures the integrity of a document.

How it works

For a legally valid digital certificate, the certifying authority must be certified by a public entity certifying the country concerned. In Spain CERES (Spanish Certification) an entity that manages these certificates.

As a mechanism to ensure both concepts (integrity and identity), the digital certificate using the X.509 standard algorithm based on asymmetric cryptography. This method uses two cryptographic keys per user: one public and one private. And it is the appropriate authority who certifies that both keys are unique per user and are properly linked.

Depending on how you use these keys, the user can ensure the integrity of the shipment and ensure the identity of the sender or sent to protect the privacy of

Ensure message integrity and identity of the sender

To ensure message integrity and ensure the identity of the sender, the short version of the procedure is as follows: the sender signs the message using its private key and sends it to other users. With this signature, all recipients can verify the integrity and identity of the message using the sender’s public key.

Protecting the privacy of shipment

Instead, to ensure the privacy of a consignment change process: the sender encrypts the message using the recipient’s public key. And this, to decrypt the message using its private key. As the private key known only to the recipient, it is impossible for a third player to decode the message (except for brute force).

How I can obtain a digital certificate?

In Spain CERES who facilitates the digital certificate. It is therefore possible to use an electronic ID or an alternative procedure

1. Certificate request

2. Prove your identity in a registry office or use your eID and a card reader to make a virtual accreditation

3. Download certificate

How do I use my digital certificate?

Digital certificates of CERES are automatically installed in your web browser. Thus, once the process ready, you can use your digital certificate for all kinds of administrative and view or submit your Income Tax Return, to request the report of your working life points or consult your driver’s license.

Also, it is possible to install the digital certificate in your mail client to sign the necessary emails. In this way, you ensure the integrity of shipments and, if desired, the privacy of data sent.

Open router ports with Simple Port Forwarding

Open router ports with Simple Port Forwarding

The advent of broadband connections preceded the boom P2P networks and multjugador games, not to mention the profits of videoconferencing and other programs that make extensive use of fast Internet connections. Most such applications require opening ports on the router, a move different for each brand and model.

Acceso al router por Telnet Until recently, the only way to open router ports was to enter commands via Telnet

At first, it was necessary to connect via the command line and execute command sequences mysterious. Now it is sufficient to enter the address of the router (usually 192.168.0.1 or 172.16.0.1), enter a username and password and navigate menus similar to that of a web page, but still not an intuitive process.

Tipica pantalla de configuracion de puertos del router Typical router configuration page (in this case, a 3Com)

There is a program that opens for you router ports. Is called Simple Port Forwarding, Is in Spanish and includes more than seven routers in its database, a number that increases with each update. It is an easy to use and avoids having to go into your router and open ports by hand. Let’s see how it works.

The Simple Port Forwarding idea is simple and attractive: choose a router, the applications you use, and allow a program to open the ports automatically. The first thing you see when running Simple Port Forwarding is a main window. Change the language from the dropdown menu at the bottom left:

Elegir el idioma de Simple Port Forwarding

Then, it is best to follow step by step wizard, "Getting Started." Have you closed by mistake? Open it again from the Tools menu. It is organized into seven steps:

Como empezar

The first updates the list of routers. This database contains, to this day, over seven hundred routers of all brands, with data connections, default passwords and commands to open ports via telnet. The second step involves looking for your router. You can use the search box or use the drop down window. To help with identification, a picture of the device in the upper right corner:

Seleccion del router

The third step is optional. Is to define a fixed IP and change, if desired, the DNS servers on your connection by OpenDNS, more reliable; and talk about them in another post. Using a static IP on the local network is highly recommended, since the ports that must be addressed always open to your machine.

Conjunto de IP

It’s time to choose the ports you’re opening. Since it is not always easy to know what they are, Simple Port Forwarding has an extensive list of applications and ports that are associated by default. But imagine that you already have installed Ares, uTorrent or eMule and defined different ports. What to do? Look at the screenshot:

Elegir los puertos – deteccion automatica

The second drop-down is responsible for P2P programs, Simple Port Forwarding looks in the settings of these programs to the appropriate ports. Not even need to copy and paste! Greater convenience is hard to get. If you still resist, click Add Custom to add a port manually. Just had to update the configuration of the router. It is the fifth step:

Actualizar el router

The Upgrade Assistant is responsible for communicating with the router and open ports selected by a predefined script. The window allows you to observe the changes through the panel, although this is not always possible (depending on model). On the left you’ll see a lot of text: the output commands entered by Simple Port Forwarding on the router.

Abrir puertos en el firewall de Windows

Ya falta menos. The sixth step opens the appropriate ports on the firewall in Windows. If you use another, you must take care yourself to authorize applications. The seventh and last step is to check if ports are open, but if you have lost patience, and open your program and try it. If so, your screams of joy echoed through cyberspace.

How about Simple Port Forwarding? Does it include details of your router? What would you improve this exciting program?

Can not load pages? Try OpenDNS

22 Dec

Can not load pages? Try OpenDNS

When you enter the name of a page in your browser without you noticing, turns into a numeric address by name servers, also known as DNS. All Internet service provider has their own DNSBut these can fail for many different reasons. The result? Without name resolution, browsing is not possible.

One solution is to use addresses OpenDNS, A free service that, for some years, offers a large network of name servers scattered around the world, ensuring far greater stability and speed. We explain how to configure your connection to use OpenDNS.

Option 1: Change the DNS addresses by hand

If you use a laptop or can not access the control panel of your router, the only solution is to change the DNS addresses of your connection. In XP, go to Home > Control Panel and opens Network Connections. Then open the Properties adapter you use to connect to the Internet:

Propiedades del adaptador de red – TCP/IP

After selecting the Internet Protocol (TCP / IP), click the button Properties. In the box that appears, it is likely that everything is configured automatically. Fourth button activates the radial Use the following DNS server addressesAnd writes the values of OpenDNS:

Direcciones de OpenDNS

Are 208.67.222.222 and 208.67.220.220. You can record it on a post-it note, a sticker or even in your phonebook. Once you have entered, double click OK for the connection to use the new name servers.

In Vista the procedure is virtually the same, but the trick is to get to the Network Connections window. Within Control PanelOpens the Center Network and Sharing or press View network status and network tasks section Network and Internet:

Propiedades de red en Vista

Click View Status and then Properties. You will see that, unlike XP, there are two TCP / IP. Which is TCP/IPv4 must edit is currently in force in most networks around the world.

Option 2: Use Simple Static IP

Simple Static IP is a tool that not only provides fixed IP address of your computer on the local network, but also assign DNS servers with one click. When open, click the button For Use OpenDNS DNS:

Simple Static IP y OpenDNS

This will change the name servers to OpenDNS adapter. To make matters worse, Simple Static IP is another button to return to the original settings of the router or use, very practical option if you do not want to miss between dialog boxes.

Option 3: Change DNS addresses in the router

If you have a multi-router is best OpenDNS enter data directly into your control panel. There are a lot of routers, and although OpenDNS offers Tutorials for the most popular brands, there’s always one escape. In general, follow these steps:

1. Access the router control panel. You can reach it with the browser, typing the address of your gateway (usually 192.168.0.1 or 172.168.0.1). If you do not know your address, open command prompt and run ipconfig.

2. Most likely, you should enter a username and password. If you do not know them, you have to test the manufacturer. In RouterPasswords.com There is a huge list of logins for each manufacturer of routers.

3. Once inside, find the page with the data configuration of DNS servers. The configuration panels usually have a similar structure. Almost always find a section in a submenu called DNS WAN, Advanced or DHCP.

4. When you see fields for primary and secondary DNS, put the OpenDNS: 208.67.222.222 and 208.67.220.220. Somewhere there will be a button to save changes. Rarely need to restart the router, but never hurts.

Why change the DNS in the router? It is useful if you have your desktop or you like using DHCP to connect to the network. Allowing the router to store the addresses of name servers, you will save the hassle of changing the settings on your computer.

Learn to share files between your PC

26 Nov

Learn to share files between your PC

Sharing files is one of the most practical to have mounted a local network at home. However, some people continue to resort to bizarre methods (sent through Messenger, set up a FTP server, use a USB key, etc.) Are needed.

Then we will explain how to do properly with Windows tools at our disposal.

Step 1. Routine checks

Of course the first thing is to have a network. Most often this is as simple as plugging both computers to the router / switch by any means (cable, WIFI). We will not go into details because it is not our goal for this text.

One thing is strongly recommended that computers among which we look to share files. Of course, is a way of speaking: no need to put a PC first;) is often said that a computer is another when it appears in the first network sites.

To do both computers must be connected, have the same netmask and preferably be in the same workgroup. You can check which group you’re working from the Control Panel> System> Computer Name> Change.

Is everything OK? Well, if there are no do not worry. You can also access another computer if you know his name or local ip by typing the following into the file browser:

\ \ Nombre_del_equipo \ \ ip.del.equipo

Step 2. Simple Thanks

Windows can make you easy or difficult. You choose. Unless you’re a security guru or a corporate network you are configuring complex, most likely with the simple way you serve. To verify you have it enabled by default, and so, you open a file explorer, Tools> Folder Options> View and check if it is not already, the last option "Use simple file sharing (recommended ). "

If not checked this option would complicate things with permissions, user accounts, domains, and others. Not recommended.

Step 3. Sharing folders

At this step is almost all done. Now it remains the easiest, go to the folder in question we want to share, right click and click

This will open the folder properties on the appropriate tab. Here you just have to tell Windows to "know what it means to share a folder and then give a name to share, if you do not already brings served. You can also choose whether they can modify or read only file sharing.

When you click OK, you’re done.

Step 4. Connect from another PC

At this step, as are the shared files. As we have seen in Step 1, there are several ways to connect to another computer on the network. From either network resources or by typing the path or IP, the result is the same. If you also know how to call the share, now we can connect directly to it:

\ \ Nombre_del_equipo \ nombre_del_recurso \ \ ip.del.equipo \ nombre_del_recurso

If you use network drives very often, you can avoid this step automatically switch to a folder on another computer by assigning a unit like a bonus disc.

Doing so is as easy as going to the File Explorer, Tools menu> Connect to a network drive. In the window choose the name of the drive you want to be specific and address of the share on another box (you can also browse web sites with the button).

There has been so difficult, right?

How to free space on hard drive scanner B

How to free space on hard drive scanner B

3 – Basic Usage

Scanner buttons perform the following functions:

4 – Example of use

Clicking on any area of the circular map enter a detailed part of the analysis. So choose a circle that looks really big (as close as possible to be a full circle) and click on it.

In our case, we clicked on my user folder and get a new map specifically:

Moving the cursor over the folders we have entered into "My Documents", which is always going to stop everything. It is also interesting to go through "Program Files" to detect gaming facilities or programs that take up a lot and no longer use.

Under "My Documents" there is clearly huge file, the green. This is a VMware virtual image of Windows XP no longer use, I have duplicated in another folder, and that is occupying no less than 2,754 megabytes (just over 2.5 gigabytes) so go for it.

Right-click on the area in question and allows us to hide the folder (not useful), retested, since Scanner enlarge (Zoom), open the folder, "Recycle", ie, send it to the trash, and "Remove" amounts to a mistranslation he meant: "to eliminate the root folder without even passing the trash".

If we are sure, choose "Remove", if we are not so much "recycled".

How to free space on hard drive scanner A

21 Nov

How to free space on hard drive scanner A

Again the hard drive full! Now what do I delete?

For many hard drives you buy, I always feel the same, sooner or later get the message that the hard drive is full. How is it possible? But if nothing had zillions of free gigs! Now what do I do?

Surely if you are a friend of P2P programs and do not get along so well with the "Delete", you are in a similar situation.

The traditional solution passes uninstall applications or games that do not use and delete anything that does not want, but the problem is to delete or not delete things but rather to find what you delete.

You can go one on one, with small file size, or attack those who eat more space. Today we’ll show you how to find the second, which is usually the fastest and most effective release a larger amount of space in less time.

Before starting, it is advisable to spend a file cleaner "unnecessary" as CCleaner. If you have never used such programs sure to get plenty of space free.

Well, once past CCleaner, we get down to work with is my favorite program for finding files to delete: Scanner.

1 – First step: Analyze

After downloading, unzip and run Scanner.exe (no installation required), the window of the program to automatically begin to analyze all your disk drives.

If you only want to scan a disk, I recommend that you click on the name, for example C:, and Scanner will deal only with that record and finish much faster analysis.

2 – Interpreting the results

Scanner displays the results in a series of concentric circles. Each of them corresponds to a folder and how much bigger the circle, the more space does that folder.

In the middle are the folders that contain the rest, and as we move outward, the files are located. Perhaps it sounds complicated but really is not. It’s all very visual and interactive.

For the cursor on any circle to know what folder it is.
