What do ou know about Methane Gas?

Methane Gas is making news headlines. Maybe your next automobile will have a tank of methane gas. Do you care?

Things you need to know:

  • Methan is also called natural gas and is used as a heating fuel and  is both man-man and natural.
  • Methane is among the most abundant fuels on the planet
  • Methane  is CH4 and is a climate change gas.
  • It is helping people live longer.

You can look up methane on the Internet. You will find many articlethat support the four statements listed above. Some articles  yu find have strong politicalbias. My purpose here is not to endorse any politicl view above another. The facts show that methane is often used in a good way. And sad to say, methane is is implicated in in human deaths.

Now here is an example of how methane improves the live of meny people every day.

Super capacitors rake the sound barrier

A researcher said it was like breaking the sound barrier. He was describing a new breakthrough in super capacitor technology.

The new breakthrough   now places super capacitors well ahead of any other electrical storage system. Compared to conventional batteries used in cars and trucks, the new super capacitors are well beyond 10 times the power of the conventional battery systems used in automobiles today. And besides transportation, the new capacitors could be used in many types of electronic devices.
Imagine having a laptop computer that does not have a replaceable battery. You just plug it in and charge it up and use it and then charges again. Even after years of use, you would not have to replace the battery, because it’s not a battery. It is a super capacitor that outperforms even with him ion batteries pound for pound.
The details are rather hard to understand for us laymen. In fact, even engineers with quite a bit of experience will find it hard to believe these new super capacitors are so great. Possibility would be a city bus that is powered by a super capacitor and goes for several miles before needing a recharge. Not only would this be quite economical, but would also have an impact on the use of gasoline or diesel to power buses.
Just imagine living in a city for all transportation was electric. If successful, super capacitors could replace batteries in any kind of vehicle and deliver more power and more talk torque and have less weight. Someday we could be living in cities where there is no use of internal combustion engines for anything.
Of course, we’re not there yet. So far super capacitors are effective in laboratory situations and have been used in some commercial applications. But at the present time they are not ready to go mainstream.
To learn more about super capacitors and the recent advances that have been made, just do a search using your favorite browser and just enter one word: supercapacitors. Yes, they’re spelling it as a single word and get describes a single thing. The difference between a super capacitor and our regular capacitor are like night and day, they are not even comparable. Go ahead. Look up. It will blow your mind.

 

Expensive Anti-Virus. Worth it?

Do You Get What You Pay For? Maybe Not.

A recent article form PC Mag had this to say about a Software Product:

Pros
In testing, eliminated active malware and malware that launches at startup, as promised. Integrated HelpDesk remote remediation tool. Installs and runs in Safe Mode. Bootable recovery environment available. Free scan available. Certified by one testing lab.

Cons
Missed many malware samples in tests. Failed to remove executable traces of detected samples. No significant real-time protection. Expensive.

Bottom Line
Enigma SpyHunter 4 does what it promises, eliminating active malware and killing malware that launches at startup. But competitors deliver much more.
Hey!, I didn’t say that! They dis. Bear in mind that PC Mag makes money off advertisers and it looks like that are not helping a growing company. Why wold they do that? Judge for yourself.

Row Hammer Virus is Worst Threat.

RowHanner is not just another virus attack on your Computer. It bleeds DRAM. It is unlike anything.

Unlike a typical computer malware, the Row Hammer takes advantage of a weakness in every DRAM memory chip in any computer.

Here is a simple explanation of what this threat means.

Let’s talk about Row Hammer. In this document I will refer to this item by the name Row Hammer. By  spelling it with capital letters it gets your attention.
This is not a new issue,  it was some time ago. But the issue was raised by the manufacturers of dynamic RAM. There are concerns that a known weakness in the design might possibly present some kind of security threat in the future. So they hired experts to analyze the theoretical and hypothetical possibilities of a security flaw in the dynamic RAM design.
So it would be correct to say this is a hardware problem and not really a software problem. Basically, that is true. For the purpose of simplification, I would like to call it a mechanical problem. Let me illustrate.
Suppose you or somebody else wanted to build a porch on the back of your house. But the back of your house is a bit higher than the rest of the house, so the question of stability of the porch would be an issue. One way of resolving the issue would be to just use bigger boards and redundant construction. But to save money, it is decided to try a novel design that uses the minimum out of would but yet provides a very steady and safe structure. After the porch has been built some and suggests that you should try getting some heavy people on the porch and see what happens perhaps to 300 pound men and see if the porch starts to sag or wobble. That would be a reasonable test. But now somebody says that if someone really wanted to give you a bad time they could put maybe three overweight man on the porch and have them start jumping up and down. Now that’s not quite fair. If they jump up and down they will put more stress upon the economical structure you have created.
In a nutshell, that is what has happened to dynamic RAM chips. I here’s a picture of I dynamic RAM module made up of many chips. Inside the chip there is an arrangement of memory cells that is of course not visible to the human eye. If you could look inside you would see something that looks like a structure of cells arranged by rows and columns. Like I said, this is a simplification of what really is inside. But the idea of a grid of rows and columns conveys the basic idea of some sort of mechanical design.
The makers of dynamic RAM chips realized that there could be a weakness in this type of design. Certain patterns of data might continually access the same row several times and this could cause the dynamic RAM cells to leak or bleed. The leaking or bleeding would cause adjacent cells to become corrupt and lose data. Is that really possible? Yes, it is and it was proven to be true. However, it takes extreme effort to come up with a sequence of binary zeros and ones that will put stress upon the memory chip. It every day use that would probably never, ever happen. But if somebody were to deliberately come up with a spatial sequence and repeat that sequence over and over again, it could cause the memory chip to bleed and spill data into adjacent cells.
Without going into the actual details of how memory cells work, that is a simplified explanation of what happens and it helps you to understand why they call the threat the Row Hammer. Yes, a malicious piece of software could constantly use a special pattern that will hit all the cells in the same row and do it over and over again like a hammer hitting a nail.
But how do we know this is true? Because the big chip makers themselves analyze the problem and publicize the problem in order to get to some recognition in the industry as to the importance of a clever design in the fabrication of memory chips. So the big famous chip makers could claim they had a better design that would resist a hostile software attack that might potentially come sometime in the future.

Well, there has been no mass use of a Row Hammer attack on the computers of the world. At least not yet. The manufacturers are so confident about this that the subject sort of died. Until this year. Specifically, last month in July. Somebody said something in July and then there’s some additional research done in August and on about August 30 a report was released saying that the Row Hammer threat was still an evil possibility.

Now one would think that with that announcement there would be a rebuttal by the big memory companies claiming they had already figured out. Well guess what? No, they don’t have it figured out. There are only a few people in the world that dabble in this sort of hypothetical threat to computer systems. They make their money by publishing articles about threats that don’t yet exist. This is a tricky business for them. If that turns out to be non-existent, they lose their credibility. But if the threat suddenly overwhelms a large number of computers over the Internet then these individuals will be criticized for not speaking up earlier. A  tough job.
So what does this mean you? Well, there’s no bottom whole lot you can do about it. Just just pay attention to some of the things that people say when they use the term Row Hammer. According to the experts it is a real possibility.
You want to learn more about how Row Hammer works, you’re going to have to read a lot of technical stuff that becomes very, very boring very quickly. I’ve tried reading over and it appears to be authentic, but I have no way of verifying this for myself. If you Google it, you may find some place where they claim that Google has a website that will offer you some different things that can test your computer to see if it would be subject to a Row Hammer attack. I haven’t tried it. The fact that it’s out there would indicate that a number of people think the threat is real.
In this document I have tried to explain what the Row Hammer threat is without getting into the deep technical stuff and boring you to death. I think my analogy of calling it a mechanical problem well represents what is going on. What happens is that two different manufacturers could be manufacturing the same memory chip by specification, yet internally there would be a mechanical difference in the layout or design. The idea is to get the memory cells as small as possible and close together as possible but to avoid bleeding of one cell to another. Exactly how they do this might remain  a secret.  Or maybe not. But the big manufacturers do believe it is a potential problem. Time will tell.

You Can Still Buy a PC with Windows 7.

Microsoft might stop vendors from selling Windows 7 this year.  Maybe.

Walmart and some other stores are still offering personal computers with Window 7. As you know, most new PCs now come with Windows 10, not 7 or 8.

But why would you want a Windows 7 PC? Is it any faster? Does it make better use of hardware? I don’t think so. If Windows 10 was not as fast, somebody would have said so by now. So why do some want 7 and not 10?

Because Windows 7 is more of a classic design for the screen layout. At least from the first screen tall you see. But it is possible to ‘customize’ the Windows 10 desktop screen to look more conventional.

Windows tip for you: Find somebody who has an almost new PC for sale and recently upgraded to Windows 10. Ask if they still have the license key used for Window 7. If so, you might buy that computer and get it to boot either Windows 7 or Windows 10 each time you turn it on.

You can Google and find ways to  legally have both Windows 7 and  10 on the same computer. It really is legal.

triple_boot

The above is from my computer, the same one I use to e3dit ;this blog. It is an old Dell Optiplex 520 with a 500GB hard drive that has three different Windows system on it. It is legal.

Now Buy Windows 10 for $80 and get a FREE PC.

The catch? The PC is an older model made by Dell  or Hp and comes with a legal installed Windows 10 system.

You can find re-sellers  certified by Microsoft to have Windows 10 installed on computers that has come off-lease. So you can help save the environment and get a great bargain. These  are model that were made over seven years ago and have been retired to make way for new computers for business firms  who lease rather than t buy.

The real attraction is  the use of a very new Operating System that woks very well with these older units. It is like getting Windows 10 at a discount and getting a free used computer. Of course these do not include a monitor. However, some newer n TV sets make good monitors. So you could pair trhe older PC with newer TV set and have a great spare computer for you or a family member.

What is the down side? The warranty is for just one-year and you would have to send it back to the vendor. Also, you can not transfer the Windows 10 software to another computer.  The rule is not new.  Microsoft has always held that a single user license  is good only for just one computer.

My advice? Check all the details before you buy one. Still, at $80 it is very attractive. By the way, some of these older units can support dual monitors without getting another graphics card.

Some models are under $80 even with Windows 10.

Windows 10 is Free If You Act Now.

There is a Legal Way to Retrieve Windows 10 without a  the product key. Read This.

Today and tomorrow will be the last chance for you to get Windows 10 under the rules that Microsoft has established.  Here is why. On Friday, July 29, the free offer will expire. Current owners so Windows 7 can either upgrade to Windows 10 or download a copy of Windows 10 and install it on a separate partition on a computer that has Windows 7. This means that you can have the accessibility of both Windows 7 and Windows 10 on the same machine. Of course, it does not allow you to have two separate computers for each operating system. It is just one license that allows the use of either Windows 7 or Windows 10 on one computer but not at the same time.

Some confusion about this rule has led many people to postpone getting Windows 10 because of fear of destroying the current system. Here are some tips to help you get a free copy of Windows 10 without losing whatever work you have in Windows 7.

The first rule is to have a backup of your current system. Backups can be in the form of a collection of DVDs or an external backup device, most often an external hard drive with enough capacity to store your operating system and your personal data. For some individuals the use of a cloud storage may be enough to make a complete copy of everything on their computer. However, the free cloud services are limited to less than 50 GB. But for a reasonable fee you can increase that to a larger size that would save everything you have on your computer.

next tip is to get the download of the Windows 10 ISO. In this context the term ISO means a image file that can be used Birt two that DVD and represents the entire actual content of the DVD, including the hidden files that make it bootable. You can download this ISO four Windows 10 from the Microsoft site right now. There is no charge for the download and you do not have to have a product key. You just select the language you want and indicate which version you want.

Here’s the third tip. Install Windows 10 on an older computer or on a spare hard drive. Then get it activated as soon as possible but before the deadline tomorrow. To activated you’ll have to have some proof that you’re the owner of a Windows 7 system.

To help you with some of the details, here is a link to another website that gives more detail about what you need to do right now to guarantee that you will have a registered copy of Windows 10 and be entitled to use it later when you feel ready. See the article below on the How To Geek web site.

You Don’t Need a Product Key to Install and Use Windows 10

 

You Can Keep Windows 7 for the Next Five Years

Microsoft said  last year that they would have a better way to update Windows 7. And it is true.

Yes, but it still is a hard thing for most home users to understand.

Here is a quotation for Microsoft about Windows 7 updates:

This article describes a convenience rollup for Windows 7 Service Pack 1 (SP1)-based and Windows Server 2008 R2 SP1-based computers. This rollup package includes most updates that were released after the release of SP1 for Windows 7 and Windows Server 2008 R2, through April 2016. This convenience rollup is intended to make it easy to integrate fixes that were released after SP1 for Windows 7 and Windows Server 2008 R2. We recommend that you include this rollup package in the image creation process to make it easier to quickly set up a computer.

For more information and the download, click on the link below:
Convenience rollup update for Windows 7 SP1

They plan to continue updates for Windows 7 until the year 2020. So that will give you nearly five years of life with Windows 7. Even it you prefere3 windows 10, for some things the windows 7 might make more sense. For example, your Grandmother might find Windows 7 easier  to learn.
