Why Companies Opt For Cloud Migration? How do companies go about migrating all or part of their IT to the cloud? What they hope for, what they worry about? From migration to the cloud, CIOs, IT leaders, and other IT-related decision-makers expect first and foremost better performance from their existing IT. They are also increasingly interested in innovations that go beyond that. Why … [Read more...]

Ready to Use LED For Breadboard With Male Headers (Arduino, Pi)
Normally we need to add a 220 Ohm resistor with LED for Arduino dev boards and similar works. Not only making that on breadboard wastes time, but also it takes time to either check the value of resistor manually or using a multimeter. The thing we made looks great and quite useful for day to day electronics development works for simple "plug and plan". We saw the idea somewhere and recreated it to … [Read more...]
Incremental Backup Versus Differential Backup on Cloud Storage
On Cloud Storage Like OpenStack Swift, We Can Set Different Backup Strategy on Our Need. Differential backup is a backup of all changes made since the last full backup which is good for quicker recovery. Incremental Backups are last full backup plus incremental changes as backups. Here is Brief Theoretical Background Behind Incremental Backup Versus Differential Backup. Incremental … [Read more...]
Arduino : Light ON One By One Following Foot Steps on Hallway
This idea is good for automatic turning on and off multiple lights one by one while a person is walking staircase or walking through a passage or hallway. As IR Obstacle Sensors has physical limits, we can not use if the passage is wide like a road - it will fail for physical reasons. Human is not much thick too! In our previous guides - Arduino IR Obstacle Detection Sensor For Dimming LED and … [Read more...]
Which is Better For Server Backup : Cloud Storage OR Cloud Server?
At this moment, we have 5800 articles on this website. If the server is gone away some way, we'll have almost nothing unless we have backup. If we have nothing, then we have to depend on sites which archive data including Google. That is not exactly perfect or easy. Most important for us is text, settings as MySQL dump. Rest is images on FTP. So, we should have regular backup. Now, Which is Better … [Read more...]
What Are RX/TX LEDs and Pins on Arduino Boards?
Why They RX/TX LEDs Blinks Upon Code Uploading? How History of Terminal Relates to it? What Are RX/TX LEDs and Pins on Arduino Boards? History of old Terminal, Telegram and Broadcast engineering. Around 150 years back, we had only way to communicate is sending pulses of current. That was the starting of analog means of connection. Slowly, when telegram improved, terminal devices became faster … [Read more...]
How To Set Up rsnapshot For Backup Of WordPress on Cloud Server/VPS
rsnapshot Once Set, Can Automatically Incrementally Backup. rsnapshot is a Free Software intended to use on CLI for server backups. It is essentially a filesystem snapshot utility based on more older tool rsync. rsync takes snapshots of local and remote filesystems, and rotates the snapshots according to your settings. Here is How To Set Up rsnapshot For Backup Of WordPress on Cloud Server/VPS. We … [Read more...]
Turn On LED in Dark With LDR and Arduino
Why we are going towards apparently easy tutorials on Arduino than couple of years back? These basic projects with components are helpful to learn using sensor based logic. Was not LCD with LDR was difficult project? Why Automatic LED Control Using LDR and Arduino looks simillar? Our older guides were mostly just using modules with libraries and this guide has more at the end for creating complex … [Read more...]
How Google Cloud Platform is Compared to IBM, OVH, DO, Linode?
We typically publish cloud host specific sysadmin guides like for Rackspace, HP Cloud, IBM Cloud and so on. We typically have no specific guides for Amazon, Azure and Google cloud. Definitely, we test zillions of cloud and traditional hosts. How Google Cloud Platform is When Compared to Other Cloud Webhosts IBM, OVH, DO, Linode? Not surprisingly Google Cloud Platform not cost effective in terms of … [Read more...]
Difference Between Analog and Digital Pins in Arduino UNO
You definitely noticed that, for the same sensor, in some project we use Analog pin, but in some other project we use Digital pin. The analog pins on the Arduino can be used as digital outputs. There is another word or phrase - PWM. Pulse Width Modulation (PWM) is a method for getting analog results by digital means, like fading LED. Let us Discuss the Difference Between Analog and Digital Pins in … [Read more...]
