Video games history – RetroAhoy: Doom [video]


Say what you want, but what Ahoy does given meaning to the life of a gamer. It puts you in a spot where you can understand games like never before, where you can take a glance at the history of games, at the ever evolving process of level creation, at techniques used to immerse you in a virtual world which contains more real life elements than you’d like to know.

Ahoy it is.

In the video from above you will learn why the video game called DOOM beat Wolfenstein to the punch when it first came out and why DOOM has so many elements of our real life like music styles, ideas, tropes, minor suggestions here and there. Or you can look at it from the technical standpoint where you see more colors being used, needing a 386 machine with at least 4 MB of RAM, and having nicer texture and a better 3D experience.

No matter on what side of the gaming spectrum you are, watching Ahoy’s videos will make you an informed gamer. It will teach you why games are art and how you are enjoying art without even knowing you do that. Watch the full documentary and then go over to his channel and watch the other videos. Gaming will not be the same again. It will be better!

Crazy machines: the Stirling Engine

What you see in the video from above is the Stirling Engine, a simple engine in which hot air moves a piston in ways you never knew possible. As you see, the piston is smaller than the cylinder it’s in. When the lower metal place is heated, the air that is at the bottom will heat up and then push the piston while going up.

Then the cool air from above the piston will be pushed down and heat up. The cycle begins again. While such an engine isn’t extremely practical, it serves quite well as an example of what engines are: devices that transform energy into mechanical work. That’s all there is to know about engines. Way for the Stirling Engine.

2016: get you pc overdose by learning about BIOS, UEFI, M.2, SATA, SAS, CPU vs GPU, extreme gaming rigs

2015 was full of IT/computer stuff and 2016 awaits the ZEN CPU architecture from AMD. Although Intel won’t reduce the prices for its processors even if AMD catches up, maybe we’ll finally see AMD CPUs being on par with Intel ones. Long history between those two, you know.

First, let’s start by learning with TechQuickie about the tech in our computers. You don’t need to remember everything said in the videos, but it will help you in the future. Nothing worse than listening to guys talking pc stuff and you being a complete noob about pretty much everything.

What is BIOS? Why was UEFI invented? BIOS is the Basic Input Output System, a software built into the motherboard itself (on a ROM chip aka flash chip) which is able to detect the components of the computer and let you run some diagnostics. It does basic stuff and can handle drives up to 2TB. This is why UEFI, Unified Extensible Firmware Interface, was created.

UEFI can use an actual graphical interface, inclusing mouse usage, will recognize drives way bigger than 2TB and is faster. Linus explains more in the video from below:

Now, what about video editing? In the era of the film you would need to physically cut and then paste a part of the film into another part. A tedious process prone to human error. After video casettes became a thing machines that could stop a video and then record a part of it onto another casette were created. Learn more about video editing and about the difference between film and video:

But what is film really? Let’s learn more about film in the video from below:

But how are CPUs made? Well, it is pretty much like 3D printing with etching combined. The factory creates a layer of silicon, then uses lasers to cut into it and create transistors this way and then another layer is setup to insulate from the next layer of silicon based transistors. A process that is impossible to do without robots and a very clean environment:

In order to make the computer faster the M.2 connector has been invented. This allows you to have flash drives installed in your computer and increase the write/read speeds up to 4 GBps, which is a huge increase. Also, M.2 drives are significantly smaller than hard drvies or SSDs.

Usually the M.2 drives use the PCI E 3.0 X4 port in order to connect to the computer. There are many types of devices that can use the M.2 port, like WiFi or Bluettoth, so you need to be careful at dimensions, usage and drive sizes.

Now, whats the difference between SATA and SAS. SATA ports allow you to transfer data from your drive in speeds up to 600MB/s, but SAS can reach up to 12 Gbps. SAS is Serial Attched SCSI and can deal with incoming and outgoing data at full speed at the same time as SATA can deal with only one type of data at a time.

SAS also uses drives that have up to 15000 RPM, but cost more and are usually used for servers, not for home usage. SAS is tipically used when you need a lot of people to access you hard drive at the same time. So, the general advice is to stick with SATA or M.2 or PCI E or with RAM drives for home usage.

Now, let go into the pc gaming realm once we’ve feasted on tech knowledge in regards to all these shiny ports. Lets see what Newegg has to say about Gigabyte Xtreme Gaming graphics cards like this 629 GBP video card:GeForce GTX 980Ti Xtreme Gaming.

If you ask me, in terms of performance Intel beats AMD in the processor world and Nvidia beats ATI in the GPU world. If you have the cash, then Intel + Nvidia is a good choice, if not, then AMD + ATI will bring you almost the same performance, but with at least 10-30% in price reduction.

When I look for a new computer, be it laptop or gaming rig, I usually look at the newest generation of i7, which is Skylake now. But each generation of CPUs has its own i3, i5 and i7 version with each having different subversions. It is crazy. Learn about these difference from PC Advisor.

Also, did you ever wanted to know the difference between a CPU and GPU? GPU is more prone to graphics and triangle calculation whereas the CPU is more prone for general works, like video processing, browsing. GPU is a specialist CPU which handles the way pixels are displayed based on the 3D model. When fewer calculations are needed a CPU can be faster, but when millions of floating point calculations need to be done, then a GPU will use parallel calculations to solve the issue much faster than a regular CPU:

Also, what is the big fuss about DirectX 12 which runs only on Win 10? Well, DirectX 12 will let you use all the cores in the CPU while in-game so this will increase the life of your processor. This is the biggest change, but will also allow you to save on power usage and offer better effects. When gaming you need to be able to use any extra performance to have a better experience.

Now that you use a DX 12 compatible video card, would gaming laptops with GTX 980 video cards worth the money? It seems like yes, they are worth the money:

Finally, I like what Jay has done with his extreme rig and with all that liquid cooling in there. I won’t go overkill like that, but it is a good to know what you can do with your gaming rig:

Learn more about liquid cooling from Maximum PC.

Bonus: what can you go with a 30 000 USD gaming rig? Well. you can allow 7 people to play with this single machine. Linus explains:

In the mega gaming rig they use two Intel® Xeon® Processor E5-2697 v3 processors with a cost of 2700USD each. Other parts:
– motherboard Asus Z10PE-D8 WS, allows 7 video cards on it and two Intel Xeon processors
– 256 GB or RAM from Kingston, 32GB each
– seven AMD R9 Nano video cards
– 1600W power supply

Happy 2016 😀

A phone battery has an energy equivalent to 40 .44 Magnum bullets


Now, that is something new, but the fact that a phone battery can hurt you is not new. Do NOT ever, under any circumstances breck the battery apart. Since it has compounds of lithium in it and since lithium is very reactive with air, the batter will start burning and will explode.

The energy stored in a battery is the same as the one from 40 .44 Magnum bullets. The word says that such a bullet can rip you head off, but closer to the truth would be that it will rip a part of you head off. The same with the battery: it can burn and hurt you if you are not careful enough. Also, try not to speak at the phone while the phone is charging.

Computer fun: how a CPU is made, aspect ratios, case recommendation


A CPU is build in a very strictly controlled environment where the transistors are build by simply building them layer by layer though a process called photolithography. Today we have CPUs in which the transistors are 14nm big. It is an incredible step since the first ICs in 1947, but basically a CPU is build from dumb things which let current flow. A transistor does not know anything about how the entire CPU much like a cell in our bodies doesn’t know or understand how the entire body works.

A book is recommended in this case: But How Do It Know. It is about how a CPU is build. It is build from dumb things which, when taken together, can do a lot of work.

Noe, let’s get to monitors. Today’s aspect ratio is 16:9, but it wasn’t always this one. 4:3 was very popular with CRT displays. If you remember those displays, then you know they could offer great color contract and images.

Also, once we’re here, you might want to take a look at what video cards are best depending on the display resolution you have. A great shift int he way the guys at Tom’s Hardware are making their reviews.

Now, if you want a quiet and a cool case for your computer, then why not get your hands on BeQuiet Silent Base 600 PC Case. Linus reviews it below:

Arabic numbers: why are they shaped like that?

cifre-indiene-unghiuri
In the image from above you can see why the numbers are looking the way they look now. We can say that we chose style over function, but you get the idea. Number one should have only one angle, number two should have two angles and number three should have four angles.

Today we do not use that exact notation, but at least we can understand now why the numbers are shaped like that. Clever guys those Indians and clever guys those Arabs who brought these numbers over to us. Roman numbers are awful to work with.

CPU history back to back: Intel vs AMD

It is about the modern processor history, mind you, the one since 1970s until now, not the one from 1826, when the differential engine was built or since 1600s, when a tax calculator was devised by Pascal or from way back before when the Chineze were using the abacus.

Intel first launches the 4004 CPU and then the 8086 with x86 architecture. After this it launched the 286, 386, Pentium I and so on.

Intel highlights:
– Intel 386dx = first to use 32 bit X86 processor, 33MHz, 4 GB RAM
– Intel Pentium = first to add MMX, multimedia extension
– Celeron 300A = first to let you overclock the processor
– Pentium III = speedstep, run the CPU at lower speeds when idle, add L2 cache, first over 1GHz
– 2002 = added hyperthreading technology
– 2004 = LGA type socket, contact pins on the motherboard, not on the CPU chip
– 2006 = Core Duo and Quad see the daylight, the end of “Gigahertz war”, added virtualization and turboboost, onboard videocard
– since then 10-15% improved performance each passing year

Now, AMD started by copying Intels 8080 processor, but then moved on to creating their own CPU and also developing X64 processors which them they licenced to Intel in order to further fuel the CPU wars:

AMD highlights:
– 1974 = AM9080 was a clone of Intel 8080
– 1976 = Intel licenced to aMD the X86 architecture
– 1996 = AMD K5 designed to fight with Pentium I
– 1997 – 1998 = AMD K6-2 captured a good chunk of the PC market
– 1999 = AMD K7/Athlon, first to run at 1GHz, used the PR rating system like 1900+ (relative to Intel processor speeds)
– 2003 = AMD lunches X86-64 architecture in K8 series (64bit processors)
– 2005 = multicore processing
– APU, FX series is created = APU has added video on board, FX for gaming, comparable to Intel

Computer goodies: history of AMD CPUs, quantum computers explained, how bitcoin works, 3D processors based on N3XT specs


There are simply too many news and videos to write about and I don’t have the will to write 3-5 long articles per day. Nor the time, actually. People have to work here, eh? But, instead I like to save the links to such videos and then post them with a short paragraph on TGTG, TehGeekTive.

It is a good time to live it. Well, when wasn’t it in the last 200 years of scientific and technological marvels? In the first video you will see Linus going through the AMP CPU history, from the first chips meant to rival Intel’s “286” up until current day. AMD started off as a company creating X86 CPUs for Intel and then went on its own path. I do hope they can keep it up!

What are quantum computers? Well, those are computers which use quantum bits, states of elementary particles which are unknown until you start measuring them. Only a number of people in the world know how such a computer should work, but you can understand more by looking at the following video:

Do you have any bitcoins? The bitcoin is a digital currency and it costs about $458 right now. Steve Gibson, from the show Security Now, has about 50 bitcoins from the days when everyone could easily mine these bitcoins. Now you need to have entire datacenters to be able to mine ie run the algorithms to mathematically spot the solutions which reveal new bitcoins.

Learn more from the following video:

I love the news section from the NCIX guys. They are always cheerful and bring us the top tech news of the day. There isn’t a single day without them. Today we learn that 3D processors aka “skycraper” chips based on N3XT specs have been developed by researchers at Stanford.

Mega sci-fi trailers: Independence Day: Resurgence and Star Trek Beyond


I know you’ve been waiting for an Independence Day sequel. Admit it. The first movie was too good for me to forget. It has action, humor and Will Smith. The sequel will not have Will Smith. His character dies in some stupid accident while the humanity is building a new fleet of war machines, but those are details.

The trailer will setup a pretty grim scene for the entire planet with more and more alien ships coming in and even continent-sized motherships ready to slam into the Earth. We knew they will return, we prepared, but will it be enough? Independence Day, take my money NOW.

The second trailer is for Star Trek Beyond. This new brave generation of young space travelers will face new dangers and test their limits. The only difference now is that they are taking a pretty heavy beating. Will they survive?

Medical Tuesday: probiotics, aspirin, and metal vs. bacteria


You guys know that I, the one man blogger-army on TGT, like to learn a lot of stuff. And stuff is enough on the web. Today we’ll learn a couple of things from the medical world namely, that probiotics are good only when you had issues with diarrhea after an antibacterial treatment, and that you should not put too much faith in them. Yup, they’re good, but not a panacea, a remedy for ALL diseases.

Aaron Carroll is not only the host and writer of the series called Healthcare Triage, but he is also a medic and a researchers. Mark his words, because he speaketh truth.

Now, let’g go to aspirin. It can help with blood circulation and, in some cases, it is recommended to eat one pill a day for a while, but this isn’t, also, a panacea. Learn more about aspirin from Dnews:

Because of MSRA, bacteria resistant to medicin, we need to find new ways to kill off bad bacteria. This is where metals like copper and silver and also nanoparticles can help us fend off these bacteria. A good thing to do is to NOT use antibiotics when you do not need them:
