We are at that point in technology when we have the tools and capacity as well as confidence to create our very own computer. With spare parts and all those good stuff, all you need is technical know-how and you can build your own computer with the speed and power that you need. However, it is really not that easy. It is very crucial to know that if you mess up your computer for the sake of an upgrade, you might end up spending more than what you could actually hope for. The question now is if computer upgrades are good or bad and if you should even consider this option than buy a readymade one?

There are some people who take upgrading as a very good exercise of their technical skills and capacity to build or enhance a computer. That sounds ideal but it requires skill so if you are a regular user without any knowledge about adding components and stuff for your computer, it would be best to have an expert do it for you.

Upgrades, to some extent can either be DIY or professional level. DIY is if you are just replacing whole hardware like monitors or maybe an entire new CPU. Maybe you want a new hard disk drive. This is probably the easiest upgrade that you could ever do. In some cases, like with regards to chips and cards and doing some software upgrades, it takes a professional in order to identify the risks, recognize the problems and ensure that the computer is working well.

Some people have conservative takes on computer upgrades. Let's face it, not all repair experts and technicians are brilliant or honest. You will see problems like haphazard installations, replaced parts or maybe even utter downgrades instead of downgrades. As you can see, it is not just about the items. It is really all about the entire system and how it will actually work for the needs and demands of the consumers. Sometimes, even if the intentions of the technician or computer owner are good, the results of the upgrade can ultimately be terrible disasters or impending disasters in the long run.

In all these things, it is necessary to take some time and ponder more about the aspects of computer upgrades before investing your money on expensive parts and fees. Here are some very useful, practical and easily implemented tips to give the real score regarding upgrades.

If it is not broken, there is no need for fixing.
Just because you have so and so computer and someone advertises that they can uplift it to become a great computer, you will just deliver your computer and pay the price. One thing to save you money and disappointment at the end of the day is that if it is doing the things you do regularly quite brilliantly, the there is really no reason to upgrade the computer. Sure, new features may have better aspects but what about the other features? Especially for software, they offer great graphics and added features but are they really worth the cost of the upgrade?

If it is broken, there is no need to fix it, either
It is like adding a new side mirror on a battered car. Or maybe a new battery for a poor running engine. It does not make sense and could potentially affect the overall functionality of your desktop. If you really must, fix the problem first. Upgrade will not fix the issue. For software, there are also some programs that can be added to make the computer run faster but be aware that some of them can cause the computer to get damaged even more.

However, that is not to say all kinds of upgrade are bad. If the purpose of the upgrade is to add better security like antivirus protection then so be it. Maybe a component is already becoming a nuisance just like bad keyboards or an ineffective speaker. Upgrading the hardware can be great. In some cases, upgrades can be great investments in the future as they can boost functionality to get things done in a shorter period of time.

While a forensic expert has the skills to properly match a recording to the person, computers still have a long way to go. Existing voice identification software programs continue to deal with several problems that hinder it from recognizing the speaker, making it ineffectual as a biometric tool. Here are a few of those obstacles.


Under extreme duress, a person's speech patterns change. His pitch rises, his intonation changes, and his volume increases. As he gets more frustrated or angry, all three factors escalate higher. Voice identification is especially difficult if his usual intervals between words have changed. This is why it's important to be calm and clear when using voice-activated commands on a mobile phone.


A cold or cough can dramatically change how a narrator sounds. Even voice identification experts will have to exert extra effort to recognize somebody whose stuffy nose hinders them from properly pronouncing their n's and m's. A scratchy throat from excessive coughing will fool voice identification software in the same way. Vault owners who are easily susceptible to the flu should always have an equally secure backup routine in place should their primary speech recognition systems fail.

External Noise

Forget about asking for help along a busy street if the toll-free number directs you to an interactive voice response system. Your words are likely to get caught in between the honking cars and revving engines. The good news is technological breakthroughs in voice identification are now enabling the software programs to separate out different sound waves to isolate human speech.

Developing Vocals

As a person ages, his vocal chords change. One concrete example can be attributed to puberty wherein a boy starts out with a high-pitched voice that becomes an almost inaudible squeak before going down to a baritone level. This makes it challenging even for voice identification experts to recognize a 20-year-old man's voice ten years ago.

Recording Quality

Background din aside, the reverberations from a recording can affect the quality of voice identification as well. These echoes are caused by the sounds bouncing off nearby surfaces. This phenomenon is what makes recording studios particular to acoustics and noise-cancelling microphones.

In no way are voice identification software programs and biometric systems on a par with the real forensic experts. As an emerging technology, the former has made several achievements in the past few years but they are still a long way from being considered a total success.

3D printing is a pretty interesting form of manufacturing technology that is already starting to change the way that we look at creating things, on any scale. Whether you are a part of a huge marketing firm, or you are a consumer working out of his or her garage, you can have access to 3D printing. What can this technology do? Well, frankly, it can create things. These things that are created range from toys, to complex parts for machinery, to character models, to jewelry, to whatever! 3D printing can create virtually anything. Before I jump into what it can make, let's discuss what takes place when it comes down to creating a print through 3D printing.

In order to use this manufacturing technology, some form of a blueprint is required. This means that a n artist, designer, engineer, or whomever will have to create a model on the computer. This model will be made through some form of 3D software. This software might be Maya, Autodesk, Solidworks, Blender, or whatever.

So an artist will work to design a 3D model, and then when the piece is finally designed, we will have the blueprint. After this is made, throwing the design into the printer I required. 3D printers will create pretty much whatever you'd like to have them create as long as enough material is available, the printer Is large enough for what you want, and you're using the right style of 3D printing for that said job. This is very powerful for designers, artists, engineers, et c, but what does 3D printing actually entail.

3D printing is sort of slang for additive manufacturing, or the layer by layer creation of various objects through a layer by layer process. For 3D printing to work, there have to be a few things. Like I mentioned earlier, a designer of some kind will have to create a 3D model of the part you're looking for. After that is done, this model will then be sent to the manufacturing facility, where it will be put into a printer. The printer technician essentially presses go, and the print starts! Layers of material will be laid down on top of this build tray, and after a certain amount of buildup, you'll see a final product come about. This is great, as the layer by layer process used in3D printing allows for the creation of some seriously unique products and images. This gives the beneficiaries a lot to work with. There is almost too much that these printers. Various materials come into play when thinking about 3D printing. Some materials feature mechanical properties, such as stainless steel or Inconel. Others offer ceramic capabilities,. Others offer things like full color from within a sandstone ZP150 printer. The possibilities as to what can come out of a 3D printer are pretty endless. There are so many options! If you're considering purchasing a printer, leasing a printer, or using a 3D printing service, it would be good idea to check it out - this technology is pretty neat!
