Our ancestors ‘ DNA helped us survive, but it’s still playing tricks on us.
Our ancestors, from prehistoric men to closer times like the Middle Ages, organized their existence around myths and beliefs that were not demonstrable, or directly false. From the time The Sun revolved around the Earth and our planet was the center of the universe, until you can die if the Sorceress of the tribe cast an evil eye on you.
Why we believe in myths? We tend to believe what best fits our mental scheme or what makes us feel better (even if it is false). Myth and posterity use a simple rule that is widely used in politics and social media: it repeats a lie a million times, and people will end up believing it to be true.
This simple rule has brought down governments, put authentic sirs in power, and made us accept as true, myths of technology that are completely false.
Since ComputerHoy.com it’s a technological website, we’ll Leave politicians, demagogues and fortune tellers to other media, and we’ll focus on bringing out seven myths about technology that you shouldn’t believe anymore.
If the signal has many bars, the connection is fast
When the tablet, the laptop or the mobile connect to the Internet wirelessly or to a mobile tower, we can see at the top of the screen icons that inform us of the quality of the signal:
As higher the Megapixel the better the camera
When they go to buy a smartphone and examine the camera, many people first look at the number of megapixels (MP) it has, and assume that the greater the number, the better. Maybe this made sense 10 years ago, when the cameras of the mobile phones were very basic and what most affected their quality was the definition, but now things are very different. It’s another technological myth to banish.
The megapixels only indicate the resolution of the photos, that is, the number of points (pixels) that make up the image. But its usefulness depends on the medium in which you will see the photos. A Megapixel is a million points, but if you’re going to see the photos on the 1080p mobile screen or on a 1080p TV or monitor, these screens only have 1920 x 1080 = 2,073,600 pixels, so a 3 MP resolution camera is enough. Even a tv with 4K resolution last generation,”only” has 3840 x 2160 = 8.294.400 pixels, so with a camera 9 MP already fulfilling that resolution. Only professional printers can take advantage of a large amount of MP, but at a very high price.
On the other hand, the resolution tells us the definition of the image, but in a modern camera that is not a quality factor. Even the simplest cell phones already have 8 MP cameras. Today it has a lot more importance to other aspects such as the opening of the lens (the amount of light capture), the optical stabilizer, the autofocus through laser, the quality of the sensor, the size of the pixels you capture, the existence of a double chamber, and other factors.
The browsers began to include a Private Mode or Incognito Mode when they grew the accusations of espionage towards the web pages, and towards the services associated with the browser, as is the case of Google.
But in practice, Private Mode is little more than a marketing operation. All it does is stop some internet intrusion and not save cookies or history on the local computer. It is useful to prevent other people who use the computer from spying on you, or websites from tracking you through cookies. But it doesn’t hide your IP address (the unique address that identifies you on the Internet), so both the websites you visit, and your internet provider that keeps all the websites you visit for at least a year, or the pages and software they deliberately spy on, will know what you do in private mode.
If you want to get real privacy you must hire a Virtual Private Network (VPN) for payment.
Unofficial chargers spoil the battery.
Official chargers ensure correct recharging, and may do so faster by offering more load or being optimized for a particular mobile. But a third party charger of a quality mark will work perfectly and will not offer any problems. Another different theme is cheap, brand-free, low-quality loaders. Those can overload the battery to the point of blowing it up, as seen in numerous news and videos on the Internet.
With a magnet you can damage a hard drive
Another of the most recurrent technological myths is that a magnet can damage a hard disk, a flash drive, and other storage systems.
The legend has a real moat, because that was the case with old hard drives and PCs. The Colecom Adam computer became sadly famous in the 1980s because by turning it on it generated a magnetic current that sometimes erased the disks.
Today, hard drives, pendrives, etc., include an anti-magnetic protection that protects against magnets. If you approach a normal magnet to a hard disk, it will not erase its contents. Only if you use a very powerful magnet, of industrial origin, and bring it directly to the disk housing, could it break down.
