What It Really Means To Go Paperless

It’s good to go paperless. In this age and age, it’s actually the way to go. Since it’s so easy to digitize files these days, it makes a lot of sense to go paperless. Just think of all the physical space you could save. You wouldn’t have to keep copies of old files in old filing cabinets that take up so much physical space.

Going paperless means getting rid of the clutter. No, it doesn’t necessarily mean that you’re going to throw everything away. You’d have to digitize all your files first to store in a virtual space. Once you’ve done that, then maybe you could throw away the clutter. It’s really up to you but you would have to be very careful.

An important follow-up to scanning is getting rid of any paper to reduce the chance of identity theft, which saw increased fraud reports in 2018, according to Federal Trade Commission findings. Of the 10 shredders we tested, Wirecutter’s favorite can take up to 10 pages at a time. For most people, the cross-cut model works just fine, but if you have particularly sensitive documents, a micro-cut shredder makes it pretty much impossible to put paper back together.

You really have to be careful when throwing out old documents. Make sure they’re shredded pretty well. If not, the information of the documents might be misused.

A good example of documents that you could digitize are your tax records. Your tax records over the years probably make up most of the clutter that you can’t seem to get rid of. If you really want to go paperless, you could start digitizing your tax records.

If your tax seasons have involved too much paper wrangling, consider throwing out your file cabinets and going paperless. Everything you have to track for the IRS you can also keep digitally.

(Via: https://www.nytimes.com/2019/04/09/smarter-living/wirecutter/go-paperless-home-office-taxes.html)

It takes a lot of work to digitize files. Imagine scanning every single file you’ve kept over the years. Nonetheless, you always have to keep in mind that you have to scan all your tax documents properly.

Gil Charney, director at the Tax Institute at H&R Block, said, “The IRS will accept electronic digital versions of documents provided that the documents are retrievable and legible, so a poorly scanned document is not going to suffice if important elements of that document are not readable.”

(Via: https://www.nytimes.com/2019/04/09/smarter-living/wirecutter/go-paperless-home-office-taxes.html)

You could always rely on an app to make scanning easy for you. However, you have to consider the fact that your tax documents are highly confidential. It contains sensitive personal information. You really wouldn’t want it to be compromised, would you?

But considering the sensitive information you capture for tax season, it’s important to choose a service that doesn’t put your documents at risk.

(Via: https://www.nytimes.com/2019/04/09/smarter-living/wirecutter/go-paperless-home-office-taxes.html)

Your important files could always be backed up to the cloud but you would really have to pay for it to add a layer of security. Cloud backup services that are free of charge might just compromise the sensitive information you have on your files. Choose a paid cloud backup service to protect your files.

You shouldn’t just rely on the cloud for storage and backup. Never keep all your files in …

Good News For Apple Users

Are you an loyal Apple fan? Well, here’s some good news for you, especially if you’re planning to buy a new Mac or you’re already a proud owner of  one.

There’s no need to pay for anything if you want data transferred to your new Mac. The data migration fee has finally been dropped.

After speaking with an Apple Store Operations Specialist, TidBITS reported that the company has dropped the data migration fee charged when users move their content from an old computer to a new Mac.

(Via: https://news.yahoo.com/apple-quietly-nixes-fee-transfer-data-old-mac-091257923.html)

That’s really good news because Apple’s data migration fee was quite high. You would really have had to factor that in if, in case, you wanted to upgrade your old Mac to a new one.

Previously, when you went to the Apple Store to upgrade your computer to a new one or had some repairs done, you’d have to pay a whopping $99 to migrate the data to your new device or new hard drive. As first reported by TidBITS on Tuesday, Apple quietly discontinued charging this particular fee.

(Via: https://news.yahoo.com/apple-quietly-nixes-fee-transfer-data-old-mac-091257923.html)

So, if you’re seriously considering replacing your old Mac, go right ahead. Now is the perfect time for it.

An Apple Store Operations Specialist told the tech news site that “Beginning April 2, there will be no cost of Data Migrations with the purchase of a new Mac or Data Transfers with a repair.”

(Via: https://news.yahoo.com/apple-quietly-nixes-fee-transfer-data-old-mac-091257923.html)

For tech savvy folks, data transfer from one Mac to another can easily be done.

Nevertheless, if you’re confident in your tech savviness, you could do so yourself at home; Apple offers a set of instructions explaining how to move content from an old computer — even if it’s a PC — to your new Mac. If you got into the habit of uploading your files to iCloud, there’s no transfer even necessary when you change computers.

(Via: https://news.yahoo.com/apple-quietly-nixes-fee-transfer-data-old-mac-091257923.html)

For folks, who have no technical knowledge or patience to deal with data transfer, they can always just go to an Apple store to get it done for free.

In any case, if you’d rather a professional handle the work, you can now go to the Apple Store to have it done for free.

(Via: https://news.yahoo.com/apple-quietly-nixes-fee-transfer-data-old-mac-091257923.html)

Data transfer is not the only issue that you have to deal with when you buy a new Mac. There are a lot of other issues that you could be confronted with. After all, anything can happen to your new Mac.

You wouldn’t have much of a problem if issues arise within the first year of your purchase. Your new Mac would still be under warranty.

It’s the same thing if you avail of the insurance they offer upon purchase. You wouldn’t have to worry if something really bad happens to your new Mac. That is, if you avail of an insurance upon purchase. What if you don’t?

You’ll only be worry-free within the first year of your purchase. After that, you would really have to find ways and means to take care of your Mac.

Considering the cost of your new Mac, you want to avoid some serious issues that could easily damage it. Hence, is the reason why you should rely on …

How to Download and Use Ansible Galaxy Roles in Ansible Playbook

Ansible is tool of choice these days if you must manage multiple devices, be it Linux, Windows, Mac, Network Devices, VMware and lot more. What makes Ansible popular is its agent less feature and granular control. If you have worked with python or have experience with yaml, you will feel at home with Ansible. To see how you can install Ansible click here.

Download-Use-Ansible-Galaxy-Roles

Ansible core modules will let you manage almost anything should you wish to write playbooks, however often there is someone who has already written a role for a problem you are trying to solve. Let’s take an example, you wish to manage NTP clients on the Linux machines, you have 2 choices either write a role which can be applied to the nodes or use ansible-galaxy to download an existing role someone has already written/tested for you. Ansible galaxy has roles for almost all the domains and these caters different problems. You can visit https://galaxy.ansible.com/ to get an idea on domains and popular roles it has. Each role published on galaxy repository is thoroughly tested and has been rated by the users, so you get an idea on how other people who have used it liked it.

To keep moving with the NTP idea, here is how you can search and install an NTP role from galaxy.

Firstly, lets run ansible-galaxy with the help flag to check what options does it give us

[[email protected] ~]# ansible-galaxy --help

ansible-galaxy-help

As you can see from the output above there are some interesting options been shown, since we are looking for a role to manage ntp clients lets try the search option to see how good it is finding what we are looking for.

[[email protected] ~]# ansible-galaxy search ntp

Here is the truncated output of the command above.

ansible-galaxy-search

It found 341 matches based on our search, as you can see from the output above many of these roles are not even related to NTP which means our search needs some refinement however, it has managed to pull some NTP roles, lets dig deeper to see what these roles are. But before that let me tell you the naming convention being followed here. The name of a role is always preceded by the author name so that it is easy to segregate roles with the same name. So, if you have written an NTP role and have published it to galaxy repo, it does not get mixed up with someone else repo with the same name.

With that out of the way, lets continue with our job of installing a NTP role for our Linux machines. Let’s try bennojoy.ntp for this example, but before using this we need to figure out couple of things, is this role compatible with the version of ansible I am running. Also, what is the license status of this role. To figure out these, let’s run below ansible-galaxy command,

[[email protected] ~]# ansible-galaxy info bennojoy.ntp

ansible-galaxy-info

ok so this says the minimum version is 1.4 and the license is BSD, lets download it

[[email protected] ~]# ansible-galaxy install bennojoy.ntp
- downloading role 'ntp', owned by bennojoy
- downloading role from https://github.com/bennojoy/ntp/archive/master.tar.gz
- extracting bennojoy.ntp to /etc/ansible/roles/bennojoy.ntp
- bennojoy.ntp (master) was installed successfully
[[email protected] ~]# ansible-galaxy list
- bennojoy.ntp, master

A Look Into Tomorrow’s Hard Disk

Data is best stored on hard disks. It is easier to access when data stored in a hard disk. Of course, they can also be stored online. While there is nothing wrong with storing data online, you would have to rely on the internet to access your files.

With a hard disk, there’s no need to rely on the internet to access your files. Since it’s very convenient to use, a hard disk with huge data storage capacity is always in demand. The thing is, a hard disk with huge data capacity might not be portable. If it’s not portable, then it won’t be that convenient to take everywhere.

Ideally, the size of a hard disk should remain small as its data storage capacity increases. At the moment, that kind of hard disk is a myth. Hopefully, tomorrow, it becomes a reality. Here’s a look at tomorrow’s hard disk.

A recent breakthrough discovery of the world’s first high-temperature single-molecule magnet (SMM) opens doors to future exciting developments in massive storage capacity increase in hard disks without increasing their physical size.

Before the publication of the study Magnetic Hysteresis up to 80 Kelvin in a Dysprosium Metallocene Single-Molecule Magnet led by Professor of Chemistry Richard Layfield at the University of Sussex in England, it was only possible to synthesize single-molecule magnets with blocking temperatures that were reached by cooling with considerable expensive and scarce liquid helium.

The team at the University of Sussex in collaboration with Sun-Yat Sen University in China and the University of Jyväskylä in Finland, reported a new single-molecule magnet (SMM) which is a type of material that retains magnetic information up to a characteristic blocking temperature.

(Via: https://interestingengineering.com/first-high-temperature-single-molecule-magnet-can-revolutionize-hard-disk-storage-capacity)

The characteristics of the SMMs are paving way to a very tiny device that could store huge data.

SMMs are molecules with the characteristic of remembering the direction of a magnetic field that has been applied to them over relatively long periods of time once the magnetic field is switched off. This makes possible to write information into molecules.

“Our new result is a milestone that overcomes a major obstacle to developing new molecular information storage materials and we are excited about the prospects for advancing the field even further,” said Professor Layfield.

(Via: https://interestingengineering.com/first-high-temperature-single-molecule-magnet-can-revolutionize-hard-disk-storage-capacity)

The fact that digital data was stored in the magnetic field of a single atom is a very significant step in revolutionizing the hard disk.

Single-molecule magnets have the potential for important applications such as high-density digital storage media as well as parts of microprocessors in quantum computers.

(Via: https://interestingengineering.com/first-high-temperature-single-molecule-magnet-can-revolutionize-hard-disk-storage-capacity)

This magnetic breakthrough is something to look forward to since we’re always looking for ways and means to store huge data in just one place.

The single-molecule magnet that is set to play such an important role in the future of quantum computing was the result of the co-ordinated effort of three universities.

The synthetic work and characterization of the prepared compounds was carried out by Professor Layfield’s research group while magnetic measurements were performed at Sun Yat-sen University under the leadership of Professor Ming-Liang Tong. Postdoctoral researcher Akseli Mansikkamäki carried out theoretical calculations and analyses at the Department of Chemistry of the University of Jyväskylä.

Including the portainer(which is a docker container image), all the exited and present running docker images are displayed. Below screenshot from Portainer GUI displays the same.

Docker_status

Monitoring events

Click on the “Events” option from the portainer webpage as shown below.

Various events that are generated and created based on docker-container activity, are captured and displayed in this page

Container-Events-Poratiner-GUI

Now to check and validate how the “Events” section works. Create a new docker-container image redis as explained below, check the docker ps –a status at docker command-line.

[email protected] ~}$ docker ps -a
CONTAINER ID        IMAGE                 COMMAND                  CREATED              STATUS         PORTS                    NAMES
cdbfbef59c31        redis                 "docker-entrypoint.s…"   About a minute ago   Up About a minute         6379/tcp                 angry_varahamihira

Click the “Event List” on the top to refresh the events list,

events_updated

Now the event’s page also updated with this change,

Host status

Below is the screenshot of the portainer displaying the host status. This is a simple window showing-up. This shows the basic info like “CPU”, “hostname”, “OS info” etc of the host linux machine. Instead of logging- into the host command-line, this page provides very useful info on for quick glance.

Host-names-Portainer

Dashboard in Portainer

Until now we have seen various features of portainer based under “Local” section. Now jump on to the “Dashboard” section of the selected Docker Container image.

When “EndPoint” option is clicked in the GUI of Portainer, the following window appears,

End_Point_Settings

This Dashboard has many statuses and options, for a host container image.

1) Stacks: Clicking on this option, provides status of any stacks if any. Since there are no stacks, this displays zero.

2) Images: Clicking on this option provides host of container images that are available. This option will display all the live and exited container images

Docker-Container-Images-Portainer

For example create one more “Nginx” container and refresh this list to see the updates.

[email protected] ~}$  sudo docker run nginx
Unable to find image 'nginx:latest' locally
latest: Pulling from library/nginx
27833a3ba0a5: Pull complete

Status: Downloaded newer image for nginx:latest

The following is the image after refresh,

Nginx_Image_creation

Once the Nginx image is stopped/killed and docker container image will be moved to unused status.

Note:-One can see all the image details here are very clear with memory usage, creation date and time. As compared to command-line option, maintaining and monitoring containers from here it will be very easy.

3) Networks: this option is used for network operations. Like assigning IP address, creating subnets, providing IP address range, access control (admin and normal user) . The following window provides the details of various options possible. Based on …

The Black Hole Becomes Visible With Half A Ton Of Hard Drives

Brace yourself. You can finally see how a black hole looks like. Up until today, no one really knew how a black hole looked like.

Finally, the day has come but it was no easy task.

The newly released image of a black hole (below) is a watershed moment for physics. Finally, we can put some of Einstein’s most famous predictions from a century ago to the test, but it was not as easy as pointing a big lens at the M87 galaxy and pressing a button. It took years of work and the collaboration of more than 200 scientists to make it happen. It also required about half a ton of hard drives.

(Via: https://www.extremetech.com/extreme/289423-it-took-half-a-ton-of-hard-drives-to-store-eht-black-hole-image-data_)

What’s interesting about how the snapshot of the black hole was the length of time it took to put it together. It took years and a network of telescopes from around the world to capture the first real image of the black hole.

Data collection for the historic black hole image began in 2017 with a coordinated effort called the Event Horizon Telescope (EHT). That isn’t a single instrument but rather a collection of seven radio telescopes from around the world. The EHT used a principle called interferometry to combine the capacity of all those telescopes, creating a “virtual” telescope the size of the Earth.

The EHT had to collect a huge volume of data to deliver us this one image. Dan Marrone, Associate Professor of Astronomy at the University of Arizona says the EHT team had to install specialized super-fast data recorders on the various radio telescopes to handle the influx of measurements.

The now-famous image of a black hole comes from data collected over a period of seven days. At the end of that observation, the EHT didn’t have an image — it had a mountain of data.

(Via: https://www.extremetech.com/extreme/289423-it-took-half-a-ton-of-hard-drives-to-store-eht-black-hole-image-data_)

The data collected was just too massive for the internet to handle. The hard drives had to be flown by plane.

According to Marrone, 5 petabytes is equal to 5,000 years of MP3 audio. There’s simply no way to send that much data efficiently over the internet. It’s faster to actually ship the hard drives to collaborators around the world. That’s why MIT has 1,000 pounds of hard drives sitting in its Haystack Observatory labs.

(Via: https://www.extremetech.com/extreme/289423-it-took-half-a-ton-of-hard-drives-to-store-eht-black-hole-image-data_)

Thanks to the EHT project, black holes are no longer just illustrations on text books. They are real.

The historic black hole snapshot not only puts to test Einstein’s predictions. It also sheds a new light on the general relativity of black holes.

Another interesting thing about the historic snapshot of the black hole is that it took half a ton of hard drives to store the data collected from the network of telescopes. The role of a hard drive is pretty significant in putting together the first image of the black hole.

What the internet can’t handle, the hard drive can. There’s just no doubt about the importance of hard drives in massive data storage.

That’s why it makes a lot of sense to say that hard drives will always be important in this data era. Considering how important and significant they are in this day and age; they’re still not …
