Open Source Experts Since 1999, Please – “Available for both Windows and Mac” Are you kidding?

This reminds me of the legendary line from the Blues Brothers movie:

“We got BOTH kinds of music – Country AND Western!”


Lame – it’s all based on Linux!  And Open Source!

Docker runs natively on Linux – the only way to get it to run on Windows and/or Mac, is to run it inside a VM (Virtual Machine), running Linux.  Ahem.

So apparently that’s what this does, although you couldn’t tell by the name, the marketing blurb, nor the description.


The Docker Toolbox is an installer to quickly and easily install and setup a Docker environment on your computer.

Available for both Windows and Mac, the Toolbox installs Docker Client, Machine, Compose and Kitematic.

cloudThis is what we’ve been saying for years now – that the best path to the cloud is to:

  1. Own your core / foundation infrastructure and hardware, at least one server worth, and
  2. Architect it properly with DRY DevOps best-practices and repeatability, to scale into the cloud as needed to meet spot demand.

Hybrid clouds are a strategic combination of public and private cloud environments, offering businesses the flexibility and scalability they need to meet their unique requirements. One crucial component of hybrid clouds is the software that enables seamless integration and management across multiple cloud platforms like Cloud 9 Software. With hybrid cloud software, organizations can leverage the best features of public and private clouds while maintaining control over sensitive data and applications. This software facilitates the seamless movement of workloads between on-premises infrastructure and public cloud providers, ensuring optimized performance, enhanced security, and cost efficiency. By harnessing the power of hybrid cloud software, businesses can create a unified and cohesive IT infrastructure that empowers them to achieve their digital transformation goals and drive innovation in the ever-evolving digital landscape.

Here’s the reference:

This is a clip of the OOB (Out-Of-Box experience) of an eRacks Ultrabook with Debian on it.

This video show the sleek aluminum finish and Full HD display, as well as the Debian splash screen and desktop.

If we have time before it ships, we will do a quick teardown video of the internals, showing the upgradeable parts such as disks/modules/SSDs, mini PCI cards, and memory, etc.

This Zenbook model is so new, we had to install special WiFi drivers and we are prepping a newer kernel for the touchpad- at the moment, everything works, except two-finger scrolling.

Your heart is the center of your health and vitality, pumping blood throughout your body to supply your organs and tissues with essential nutrients and oxygen. So it makes sense that if you follow a heart-healthy diet, it can help your cardiovascular health and everything else that your heart affects. Check out these prodentim reviews.

At Ross Bridge Medical Center in Hoover, Alabama, primary care provider Madhav Devani, MD, and his team encourage patients to eat with their heart in mind. So to encourage you to do that, Dr. Devani explains five major benefits of eating a heart-healthy diet.


A heart-healthy diet plan consists of eating foods that will help you improve your cardiovascular system and overall health. This type of plan typically involves the following strategies:

  • Controlling your portion sizes. Visit prodentim website.


  • Adding more vegetables and fruits to your meals and snacks


  • Opting for whole grains


  • Limiting consumption of unhealthy fats, such as those found in red meat and dairy


  • Relying on low-fat sources of protein, such as skinless poultry and lean fish


  • Cutting back on salt in your meals and snacks

A heart-healthy diet plan also includes plenty of exercise. You should aim for at least 30 minutes of exercise — such as walking — for 30 minutes a day, five days a week.


There are many benefits of consuming a diet with your heart in mind. Also taking dietary supplements like alpilean, looking for

Alpilean Reviews

are a great way to find out about the potential health benefits of taking Alpilean for heart health. Reviews often provide insight into personal experiences using the product, as well as information from medical professionals. Checking out Alpilean Reviews can help you decide whether this supplement is right for you, and if it can improve your overall heart health.

  Here are some of them:


Eating a heart-healthy diet can benefit your blood pressure, blood sugars, and triglycerides. If you’re concerned about high blood pressure, or if you have a condition that causes blood sugar swings, such as diabetes, then changing your diet to be more heart-healthy could improve those issues as well. Learn more about kerassentials.

For patients with high blood pressure, the Ross Bridge Medical Center team often recommends the DASH plan, which stands for “dietary approaches to stop hypertension.” The DASH diet focuses on the following:

  • Limiting sodium intake


  • Limiting saturated fats


  • Reducing sugar intake


  • Consuming more foods rich in potassium, calcium, and magnesium, which are nutrients that actively help regulate blood pressure


Cholesterol can clog your arteries, which deliver blood from your heart to the other tissues in your body. This, in turn, can lead to a heart attack. Heart attacks occur in the United States about every 40 seconds. Fortunately, eating a heart-healthy diet can help lower cholesterol levels.

Dietary strategies include decreasing consumption of saturated and trans fats, which are often found in processed foods, red meat, and dairy.  These fats should be replaced with monounsaturated and polyunsaturated fats, which are found in olive oil, sunflower oil, avocados, and nuts.

And, consuming more fiber, such as that found in oats, legumes, flaxseed, apples, and citrus fruits, can also help lower your cholesterol levels.


Taking the steps needed to protect your heart, such as eating a healthy diet and getting active for at least 150 minutes of medium-intensity activity every week, can also affect your waistline. By eating right and exercising, you can improve your heart health and enjoy a more trim figure.


Having a healthy heart can also help you have more energy. And foods that can help keep your heart healthy, such as nuts, seeds, avocados, olives, lean meat, fish, whole grains, fruits, and vegetables, can give your heart the vitamins, minerals, and nutrients it needs and help keep you energized at the same time.


Heart disease is the No. 1 cause of death in both men and women worldwide. Furthermore, heart disease is the cause of one in every four deaths in the United States. For weight loss in those suffering from heart disease, doctors typically recommend a combination of dietary and lifestyle changes, such as eating a healthy diet that is low in saturated fat and salt, and increasing physical activity. Prescription medications such as the best weight loss pills for women can also be used to support weight loss goals.

So, if you can improve your heart health by making changes to your dietary choices, you can potentially increase your longevity and extend your lifespan.

Creating wealth requires smart investing which is something you have to learn if you want to achieve financial freedom. In the following paragraphs you will learn how to select, invest in and manage high quality mutual funds that can actually generate the required returns, you’ll also learn about online trading.

First, you need to understand the difference between a taxable and tax-free bond, as it will be the largest portion of your mutual fund holdings.

The tax advantage of a bond is that it does not have to pay a capital gains tax when you sell it but you have to pay income tax when you withdraw the money when it is sold. In contrast, a mutual fund pays no taxes when you sell it. As such, the bond will pay a lower tax rate than a mutual fund. Also, the bond’s yield is higher than a mutual fund. If you have $100,000 in your IRA and you sell a $1,000,000 bond, you will end up with $99,999.99. This is a 5% yield, which is much better than the 2.5% yield of the bond. This means you will make $5,000 more, but you will have to pay taxes on it. In some states, the tax will be higher. The best way to reduce your tax bill when you sell a bond is to roll the bond into another retirement account, such as a Roth IRA.

To be sure, you may want to look at mutual funds. It’s easier to do this than roll bonds into a Roth IRA because you only need to sell one bond. This bond will be converted into another mutual fund, which will be converted into yet another mutual fund, and on and on.

What if my IRA provider won’t take me to another mutual fund if I use another company’s bond?

A bond is a bond. No, this isn’t some kind of weird, “weird” bond, it’s a bond. If you get a new investment manager and she doesn’t offer a bond fund for you, then you have options.

Option #1: Look for an exchange-traded fund that is similar to the fund you want to work with. Exchange-traded funds are mutual funds that track the performance of a broader market index, such as the S&P 500 index. These funds are available to retail investors who invest using a brokerage account, a 401(k) plan or a high-yield bank account. An exchange-traded fund provides the investor with a price, which they can then use to buy or sell the underlying index. ETFs provide you with the ability to buy or sell securities at a pre-set price, so that your holdings can match the movements of the market. ETFs can be traded in different ways, such as over the counter (OTC), over the phone, through the Internet or through mutual fund brokers.

For the first 10 years of trading, you don’t need to invest in any individual exchange-traded fund. Instead, you can simply buy a mutual fund that includes the shares of an ETF.

But it is crucial to understand that ETFs are actually stocks, which means that when you invest in them you’re investing in the overall market. In fact, the market, like a giant pyramid scheme, is a giant investment scheme, because it is in fact designed to make money for the people running it.

Ubuntu for tablets was officially unveiled today. According to PCMag, “A Touch Developer Preview will be released on Feb. 21 via, which will work on the Nexus 7 and Nexus 10 tablets.”

Ubuntu for Tablets

I’m actually a huge fan of the interface on the Nexus 7 and I probably wouldn’t change it, but I would absolutely love someone to get a stripped down version of Ubuntu running on a Kindle Fire. I absolutely hate that my Kindle Fire won’t recognize a USB device and can’t access the Google Play Store without rooting it and potentially bricking the device. 

Some of the added features of Ubuntu will be voice control, an invisible task-bar called magic edges,  and a split screen mode to allow for better multitasking: Skype while you watch a movie at the same time.

boxOne of the primary complaints that I’ve had about tablets such as the iPad, the Surface tablet and the Kindle Fire HD is the lack of hard drive storage space.  All three devices offer between 5-10GB of additional cloud storage for free, but that’s barely enough for a single DVD quality movie.  There are plenty of paid options for cloud storage, but many services charge a monthly/yearly fee and they can be expensive. Recently, as hard drive prices have been dropping, I’ve been expecting that some company would finally come along and offer a large amount of free cloud storage to sign up a bunch of new users. I saw a post on a forum today where was offering 50GB of free cloud storage to new users.  I haven’t had a chance to test the service myself, but it can apparently sync files between Apple, Microsoft, and most Android devices. I recommend signing up for this deal as soon as possible, because I highly suspect that the folks over at have vastly underestimated the number of people who are going to jump on a deal like this.
