Dear All,

Considering the digital world expansion and acceptance the day is very much nearby where digital crypto currencies are taking over the world and redefining the payment standards online.

Bitcoin is the world first crypto currency which has emerged to be so successful that it one bitcoin is valuing to 4198.57 US Dollar when I am writing this post. There has been more than 200% increase in it’s value compared to previous year of 2016 and acceptance of bitcoin has increased & various ecommerce portals,hotels,restaurants have started accepting it.

Major question surrounds how you can buy/sell bitcoins or you can mine bitcoins. Bitcoin mining is the process of using your optimal hardware to run a mining software to solve mathematical problem by generation of hash code and then it gets converted to blockchains which in turn gives you some x amount of bitcoins on each solution of mathematical problem solved.

As per NASDAQ :- http://www.nasdaq.com/article/what-is-bitcoin-mining-cm736542

Though it’s hard to mine bitcoin now a days on your local desktop or computers as network of billions of people mining thousands has increases so your share also gets segregated into fractions so the people are now trying to buy bitcoins and sell it as per the market demand. Many websites and mobile applications are there who are selling/buying bitcoins.

Some of them are as below :-

I cannot predict more about the future of bitcoin but yes acceptance of digital cryptocurrencies is increasing. There are many  other digital crypto currencies which have emerged such as Ethereum,Litecoin, dash etc. More information on :- https://99bitcoins.com/bitcoin-alternative-6-coins/

Being a linux fanatic & enthusiast CGMiner is an opensource software for mining in linux. There are many others which are opensource & can be used in windows,mac & linux.

Hello Friends,

In today’s world on premises infrastructure is been reducing due to majority of the giants,SME’s are going for cloud based hosted infrastructure unless there is a need of major security applications like banking sector etc but now they are also following the approach of P2V(Physical to virtual) and V2V(Virtual to Virtual).

Vmware Converter tools are being rapidly use for this migration. You can use the converter to convert your VM images to migrate to another environment and also to cloud.VMware vCenter Converter Standalone is a free tool that shops can use to import VMs from other virtualization platforms into vSphere or perform a hassle-free P2V & V2V migration.

If you want to know some detailed steps below links might help :-

Hi,

It was a golden opportunity to recreate a small tribute to a lovely track 0 0 Jaane Jaana a small tribute to Salman Khan Sir this song created waves and broke records..brought the gym culture & torn jeans etc…Made from heart,soul..got an opportunity to be a model and director on this project..though we cannot be an inch to what Salman lovely bhaijaan did..but an honest attempt..hope you all would love it.

Enjoy.Cheers

In layman terms Devops is a methodology that communicates,integrates,simplifies the process of software development & information technology making developers & IT admin guys to work together building an automated development process. Devops from my understanding is development + operations.

Devops is a hot cake currently as all IT firms are in need of devops engineers for automating their micro-services, software development needs & IT operations so that releases can be steady & automated.  As we talk about open source & fanatic about it there are various tools I have listed which are quite useful in devops.

1. Nagios :- A great monitoring tool for monitoring/alerts with full customizations for you & tons of plugins which is ease of use.
2. Monit :- Sometimes the simplest tools are the most useful, as proven by the simple watchdog Monit. Its role is to ensure that any given process on a machine is up and running appropriately. For example, a failure occurs in Apache, Monit will help to restart the Apache process. It is very easy to setup and configure and is especially useful for multi-service architecture with hundreds of micro-services.
3. ELK-Elastisearch,Logstash,Kibana :- The ELK Stack is the most common log analytics solution in the modern IT world. It collects logs from all services, applications, networks, tools, servers, and more in an environment into a single, centralized location for processing and analysis.
4. Consul.io :- Consul is a great fit for service discovery and configuration in modern, elastic applications that are built from microservices. The open-source tool makes use of the latest technology in providing internal DNS names for services.
5.  Jenkins :- Everyone knows Jenkins, right? It’s not the fastest or the fanciest, but it’s really easy to start to use and it has a great ecosystem of plugins and add-ons. It is also optimized for easy customization. We have configured Jenkins to build code, create Docker containers (see the next item), run tons of tests, and push to staging/production.
6. Docker :-Everything that can be said about how Docker is transforming IT environments has already been said. It’s great…life changing, even — (although we’re still experiencing some challenges with it). We use Docker in production for most services. It eases configuration management, control issues, and scaling by allowing containers to be moved from one place to another.
7. Ansible :- Again, simplicity is key. Ansible is a configuration management tool that is similar to Puppet and Chef.  Personally, we found those two to have more overhead and complexity to our use case– so we decided to go with Ansible instead.
8. Collectd/Collectl are nifty little tools that gather and store statistics about the system on which they run and are much more flexible than other tools. They allow users to measure the values of multiple system metrics and unlike other log collection tools that are designed to measure specific system parameters, Collectd/l can monitor different parameters in parallel
9. Git was created 10 years ago following the Linux community’s need for SCM (Source Control Management) software that could support distributed systems. Git is probably the most common source management tool available today.

There are many  other tools available for devops as per your requirements including various tools being developed daily.

Dear All,

Today I am glad and proud that my movie “The Linux Guy” has been released on Amazon Prime & Instant Video.  It’s a great feeling that a project which started of a dream in the night comes true after an year of struggle,hard work,patience & diligence. Please feel free to give your reviews,watch,love & share. It has been released in US,UK & canada for the time being, it would be coming in other regions very soon too.

Hello Friends,

There has been lot of discussion about which open source firewall,proxy etc you can use for your organization. Lot of queries have been asked to me for the same.

I personally believe that any firewall cannot prevent you entire from attacks you have to in place a proper unified threat management systems installed at your gateway through which you are providing internet access to your employees in your organization.

There are various commercial choices like sonicwall, cyberoam, sophos, untangle etc but if you know how to use open source components you can configure your own UTM easily. Along with open source UTM’s like ipcop, pfsense,shorewall, clearOS is my personal favorite choice still I won’t say any network is 100% secure because you have malicious softwares like malwares,trojans, viruses getting spreaded daily so in order for providing a robust security I would suggest to through my link posted previously on http://www.alokthaker.com/2016/01/21/hardening-and-securing-your-linux-os-servers/

Please feel free for any comments or queries. Going to write on creating your own jarvis soon using python in my next post stay tuned.

Well days have been great this far in 2017…The Linux Guy has been liked and praised in international film festivals including my IMDB starmeter ranking being in top40k list with a starmeter of 39252 with likes of various million celebs in the world.

It feels great when you achieve that kind of feat.

I feel a great sense of accomplishment achieving the success which required lot of hard work,pains, financial troubles to make the linux guy a dream project. I am also working on my next project Things To Do which is also a great storyline including Johny a web series consisting of mixed martial arts and a griling drama plus action.

On Linux front I would start some interesting posts by next week and get it more tight and intact on hot topics which would be helpful for all the linuxites.

Thanks for all the love,support and kindness to me and my movie “The Linux Guy”.

Love,

Well there has been a debate about faster transfer with security. There would be people having different views on which command you should use for faster file transfer with security and some would also require to resync the data if there is some interruption during traffic etc.

From my side I have used scp and rsynch for remote copy but coming to the conclusion in terms of stablity and reliability I would suggest to go for rsync and not scp. scp can definitely score over rsync in file transfer as rsync build as file transfer list wherease scp just uses ssh protocol to copy the data and put it on remote.

#scp -r test alok@alok01:/opt

The above command would be more faster to copy test directory with alok credentials to servername say alok01  to /opt directory on remote host but what if your transfer breaks or interrupts you have to go back and start the copy again but in this case rsync comes into picture providing more stablity.

#rsync -avz test alok@alok01:/opt

The parameter -a also makes the copy recursive and preserve the modification times, but additionally it copies the symlinks that it encounters as symlinks, preserve the permissions, preserve the owner and group information, and preserve device and special files. This is useful if you are copying the entire home folder of a user, or if you are copying system folders somewhere else.z used for compressing the files while being transferred. Now suppose here your network halts or interrupts would you again do a rsync. Yes but rsync won’t copy the files which are already copied and save your time and patience.

Suppose from you remote host you have deleted any directory or file or updated anything you can always use –delete-after option to run rsync again after interrupted or new transfer too.

#rsync -avz –delete-after test alok@alok01:/opt

Hope this makes you understand when you should use rsync and when scp as per your convenience.

For windows you can always use cwRsync (https://itefix.net/cwrsync) for incremental copies,backups etc and also deltacopy (http://www.aboutmyip.com/AboutMyXApp/DeltaCopy.jsp). Winscp(https://winscp.net/eng/download.php) is alternative for windows being scp in Linux.

Feel free for any comments or queries.

Thanks & Regards,

There have been very few or almost none a song on Linux being one of my favourite OS. So  I asked my music director to help me a nice song as my movie is titled “The Linux Guy”.

The Linux Guy is an interesting english movie which is going to be released soon. It’s a great story line of losers turning into achievers, talking about youth who are going through a lot then how does a teacher arrival’s in the college turn the things around for them. This movies talks about college days and would definitely bring lots of great memories of your college life. Jack and Jill are our 2 wannabe rappers how they turn a rapper finally and there is Roshan who is a complete loser how his life turns around doing the project under Alok Sir. Ronnie is a bad boy in the college.Jasmeet an independent working girl in private bank who plays Roshan’s love interest and their issues There is love,drama,fights,family issues, friendship and project of the year award competition etc

So I want an emotional connect in the song and it took lots of understanding/brainstorming sessions to make this song possible and I hope all linuxites,linux lovers would love,watch and share this song from my movie “The Linux Guy”. It’s great that we also got listed on imdb :- http://www.imdb.com/title/tt6157390/

Please don’t forget to watch this song. Please love,share and subscribe.

Love,
