Referencing/Sharing asset information from webpack to Rails is the problem being solved in this post. We want to use the webpack assets that are exposed in our Rails app. Not setting up a new plugin for uploading the generated assets would be a plus. Our team used webpack to compile javascript and related assets. (If you are trying to learn webpack, note that it has a very steep learning curve). https://sairam.dev/post/2017-04-15-devoops-talk-cloud-security/ Sat, 15 Apr 2017 09:11:36 +0530 https://sairam.dev/post/2017-04-15-devoops-talk-cloud-security/ Its a long list of slides about Security with the NoSQL, SQL and other tools used . I thought I’d make a short notes, but its worth reading every slide of the presentation Devoops Security Notes - How to avoid losing customer data and money https://sairam.dev/post/2017-04-14-install-older-ruby-rvm-on-mac-10.10/ Fri, 14 Apr 2017 16:01:36 +0530 https://sairam.dev/post/2017-04-14-install-older-ruby-rvm-on-mac-10.10/ If you are installing 2.1.x or 2.2.x versions of ruby from 2014/2015, support is missing for some of them. gem install stops working with the default gem that installs via rvm when installed on Mac OS X 10.10 (OS X Yosemite) This is the error I faced. You get the error ERROR: Could not find a valid gem 'rubocop' (>= 0), here is why: Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://api. https://sairam.dev/post/yearly-reviews-the-good-parts/ Wed, 12 Apr 2017 22:00:00 +0530 https://sairam.dev/post/yearly-reviews-the-good-parts/ The yearly or half yearly performance reviews are the things every one looks forwards to, loves and hates. This is the only process where people get emotional and the details are personal. There are companies which only do only self reviews and those who add a 360° feedback. On the other hand there are startups where this process is cranky and screwed up( err., not so well organised). We hate the tools the HRs choose and the way the tools get stuck to on the last hour when everyone is trying to submit/finalize their reviews. https://sairam.dev/post/2017-04-11-a-clean-way-of-deploying-code/ Tue, 11 Apr 2017 23:30:05 +0530 https://sairam.dev/post/2017-04-11-a-clean-way-of-deploying-code/ Think of the tools like Makefile for C / C++ or yarn or nom in Javascript or bundle in Ruby or requirements.txt in Python or maven.xml in Java. Now the same applies to the operating system as well, in the operating system, you can add additional stuff outside a package manager which is hard to maintain or guess. You can do the same in the languages for libraries or ad-hoc code which was not intentionally to be present. https://sairam.dev/post/2017-04-11-identifying-bad-tests/ Tue, 11 Apr 2017 22:00:00 +0530 https://sairam.dev/post/2017-04-11-identifying-bad-tests/ Look at this code Rails FactoryGirl definition for a regular user class FactoryGirl.define do factory :user do first_name "John" last_name "Doe" subscription_end_date Date.parse("2019-01-01") end end Does not look harmful. This is a base model. When your other spec files start using it, everything will work fine when you evaluate the subscription_end_date with other fields, but, exactly after 2019-01-01, on 2nd Jan 2019, the tests dependent on this value will start failing. https://sairam.dev/post/how-to-track-user-agreement-acceptance-in-db/ Mon, 10 Apr 2017 22:30:00 +0530 https://sairam.dev/post/how-to-track-user-agreement-acceptance-in-db/ Problem Statement How would you model to check if a user has accepted your “Terms and Conditions” or “COPPA” when building your website? Lets talk how would you track in your data store (MySQL or Postgres or Mongo DB). The front-end is represented by a checkbox or click of a button ‘I Accept’, this translates to either a true or false and gets stored into the a column in the users table in your database which is a boolean field. https://sairam.dev/post/sde-levels-at-product-tech-companies/ Sun, 09 Apr 2017 22:30:49 +0530 https://sairam.dev/post/sde-levels-at-product-tech-companies/ When developers join a Product Technology company, they get confused by all the different types of roles in a company. I will start describing from the SDE job family. A job family has multiple levels. These levels are awarded to the employee based on their current skill. It usually corresponds to the salary as well. Being knowledgeable about the levels at Amazon, Flipkart, I will consider Flipkart job levels since the company has been a golden standard in the Indian tech industry. https://sairam.dev/post/generating-header-images-for-blog/ Sun, 09 Apr 2017 16:40:00 +0530 https://sairam.dev/post/generating-header-images-for-blog/ Inspired by Sense-Si, the process fills in text into a HTML page and uses a PhantomJS (on a docker container) and takes a screenshot. I wanted to see if I can make these in a simpler way with other tools I currently use already.

Post the creation of Insta Paper, everyone wanted to read their information in a clean way, those who cannot tried to push it to their Kindles or Evernote. These people read a lot and wanted to read a lot. When you push to other devices, you may lose count on what you need to read. https://sairam.dev/post/cli-productivity-fzf-yank/ Wed, 05 Apr 2017 20:00:00 +0530 https://sairam.dev/post/cli-productivity-fzf-yank/ fzf Came across an powerful CLI fzf utility.

You may have seen this Data Visualization Talk from couple of years ago. Data Visualization by GapMinder is a proper tool for analyzing large sets of data. This video below is dated (2003), but the tool can be used as-is at gapminder.org/tools The vision of GapMinder is to fight ignorance with a fact based worldview that everyone can understand Other Tools Gap Minder Desktop Tableau Juila Plots Finding the types of charts Start off here to learn what Chart Types to use for the situation http://www. https://sairam.dev/post/bypassing-the-paste-restriction-on-browsers/ Sat, 18 Mar 2017 12:00:00 +0530 https://sairam.dev/post/bypassing-the-paste-restriction-on-browsers/ Banking sites and Mac OS Keychain makes you intentionally type in your credentials. These can be usually bypassed with help of browser specific extensions using Password Managers like 1Password or LastPass. Its also important to note that have their own downsides aka bugs. Being a developer using a keyboard for hours every day since 10+ years, being productive will become a mandatory requirement for me personally. By unblocking websites and Mac from restricting me to use the bypassed paste, I feel invincible on the keyboard. https://sairam.dev/post/new-landing-page-on-gitnotify/ Sun, 12 Mar 2017 13:20:00 +0530 https://sairam.dev/post/new-landing-page-on-gitnotify/ Deciding to make a new landing page instead of having just the screenshots https://sairam.dev/post/2017-03-11-how-to-scale-ip-at-dc/ Sat, 11 Mar 2017 23:00:00 +0530 https://sairam.dev/post/2017-03-11-how-to-scale-ip-at-dc/ Scaling app servers to nearly unlimited size is easy to explain but really hard in practice. It basically amounts to this: Balance requests using DNS anycast so you can spread load before it hits your servers Setup “Head End” machines with as large pipes as possible (40Gbps?) and load balance at the lowest layer you can. Balance at IP level using IPVS and direct server return. A single reasonable machine can handle a 40Gbps pipe…. https://sairam.dev/post/making-cheatsheets/ Wed, 01 Mar 2017 23:42:04 +0530 https://sairam.dev/post/making-cheatsheets/ I used to be a Google / Stack Overflow junkie for syntax issues or finding configuration/compatability issues in the vast amount of dimensions software gives us. An approach I used to solve this problem was to document snippets once I have solved the problem (don’t forget to upvote the answer on SO). This is especially useful when you start learning a language.

If not, why not? Why don’t you start a blog today targeting a typical customer and start posting 500 words every three days?

Writing is the best way for learning a new language and appreciating the beauty. This is my 2nd Go project github.com/sairam/gitnotify hosted at GitNotify. The project aims at notifying users periodically about the new code changes that went it. I felt I was missing out new merges happening in smaller projects while learning a language. I found amazing libraries in Go and wanted a way to get weekly diffs to understand what happened. https://sairam.dev/post/concurrency-is-not-parllelism/ Fri, 18 Nov 2016 17:49:51 +0530 https://sairam.dev/post/concurrency-is-not-parllelism/ Concurrency Is Not Parallelism https://sairam.dev/post/2016-11-01-why-i-like-go/ Tue, 15 Nov 2016 23:06:56 +0530 https://sairam.dev/post/2016-11-01-why-i-like-go/ I have been reading and listening a lot about GoLang. There are two great projects with good communities and Documentation Caddy Hugo Why I like go? The standard library is too powerful Creating a http server is very simple Interfaces are too good and provide the best Structs are the new classes (no inheritance, only composition) Concurrency is a first class citizen (via go method) structs for locks are part of the stdlib Syntax is a first class construct, all go code looks the same Terrific garbage collection in order of nano seconds Data can be passed through streams(channels) With this power and the speed Go runs at, I started learning Go by writing a simple productivity tool (my first project in Go), Pastebin via API, named it daata (Check daata-server/ directory) https://sairam.dev/post/migrated-to-hugo/ Tue, 15 Nov 2016 23:02:40 +0530 https://sairam.dev/post/migrated-to-hugo/ I have been using OctoPress since a while. Octopress uses ruby and doesn’t work quite well for 1000s of posts (or so the claim goes). I wanted to try out Hugo because of the hype of great software and fastness of generation of the static site. Related: Why I like Go?. Why change?

The aim is to provide a tool where the complete company can share data as well as information. Running commands on all machines is the standard thing, but capturing the output and cleaning that up is usually a matter of making scripts to clean up the data especially when you are debugging during downtime of your service. https://sairam.dev/post/screen-capture-on-mac/ Sun, 18 Sep 2016 18:00:00 +0530 https://sairam.dev/post/screen-capture-on-mac/ (This article was intended to be written on 18th Sep 2016, but actually written on 8th April 2017) In order to take a screenshot on Mac, the standard way is to the Grab application.

The entity has been through several transitions. People have feared and moved out and became in-active. del.icio.us the most famous domain hack around 2008. Yahoo bought it, later sold it and I don’t know what happened later on. Then, starting around Dec 2015, Delicious started popping up Advertisements.

I reside in Koramangala which is a sub-locality which has one too many restaurants. People think Food Startups are supposed to solve the problem of Discovery — To allow the customer to identify what are the restaurants near them and Conversion — To help order with ease and get the items delivered There is another problem which is not taken into account and there is no solution. https://sairam.dev/post/2015-12-30-opensource-contribution/ Wed, 30 Dec 2015 23:00:00 +0530 https://sairam.dev/post/2015-12-30-opensource-contribution/ This was one of the open source contribution in 2015 to a major Rails project used by e-commerce companies. It usually takes hours/days to understand the basic framework, goals, motivations, features vs limitations etc., to start contributing to an open source project based on the amount of domain knowledge (especially for matured projects). Its usually hard to find and understand bugs in a very well mature framework or language. One of the good things about using open source libraries is you get to know both the code and get to know the eco system while getting paid on the job. https://sairam.dev/post/csshx-with-lincastor-on-mac/ Thu, 24 Dec 2015 17:20:00 +0530 https://sairam.dev/post/csshx-with-lincastor-on-mac/ Problem Statement: I want to SSH into a list of hosts from the browser(from a host monitoring UI). Note: At this point of time, we did not have Service Discovery present. To identify this, in our team, we maintained a single service which has this list.

Its the era of the cloud and sharing. Pictures are the fastest way to capture a moment. A picture is worth a 1KB of words (but sized about a few MB). Sharing and saving photos, videos are getting famous and easy with cloud storage from each of Adobe, Amazon, Google, Dropboxalong with Flickr(now providing free 1TB of storage). https://sairam.dev/post/2013-05-21-bookadda-gets-its-data-from-barnes-and-noble/ Tue, 21 May 2013 18:05:00 +0530 https://sairam.dev/post/2013-05-21-bookadda-gets-its-data-from-barnes-and-noble/ Looks like BookAdda gets its data from B&N :/ https://sairam.dev/post/2013-05-17-omgrofl-programming-language/ Fri, 17 May 2013 22:13:00 +0530 https://sairam.dev/post/2013-05-17-omgrofl-programming-language/ Sweet Syntax - Omgrofl - Esolang. https://sairam.dev/post/2013-05-17-programming-language-trends-drew-conway/ Fri, 17 May 2013 20:55:00 +0530 https://sairam.dev/post/2013-05-17-programming-language-trends-drew-conway/ Find the Hot Programming languages from the Programming Language Trends. https://sairam.dev/post/2013-05-16-competition-monitoring/ Thu, 16 May 2013 14:18:00 +0530 https://sairam.dev/post/2013-05-16-competition-monitoring/ A bookcosts 11.36 Lakhs.

It makes sense for certain news reading sites like Google Reader or Social sites or even Blogs to have endless scrolling. Sites like Flipkart have implement it in not so good way. If you want to browse all the items in a category or in a search result with 100’s of items.

Even for the skeptics, it’s difficult to argue that these acquis- itions are about anything other than people. In many deals, like Facebook’s acquisition of Gowalla, the technology was not even a part of the transaction. And when the technology is included in the transaction, it is frequently released as open source post-acquisition.

Ruby on Rails is a famous choice in the US/England for fast development of websites. PHP is the most famous one for Indian startups (I think its mostly because of the number of people).

A plugin is an addon so that you can use the power one software from another. Well if they share functionality, they might as well share security issues. This is the first post on Security. If you haven’t heard about a security breach or a botnet or a website or computer hacked, its time to know. A website being hacked means extracting data illegally which could have been possible because of a bad configuration or the software not begin up to date. https://sairam.dev/post/2012-09-02-well-there-is-lot-of-airtraffic/ Sun, 02 Sep 2012 00:00:00 +0000 https://sairam.dev/post/2012-09-02-well-there-is-lot-of-airtraffic/ Well, there is lot of traffic https://sairam.dev/post/2012-09-01-hello-jekyll-server-config/ Sat, 01 Sep 2012 00:00:00 +0000 https://sairam.dev/post/2012-09-01-hello-jekyll-server-config/ Note: This post was moved from 5erver.in (spelled server.in) Intro about 5erver.in I want to write posts about resources and configurations I find when configuring websites to desktop software.
