Hubot - www.craigpardey.com - 10 years ago - eng
Configuring Hubot to work with a self-hosted HipChat server took a bit of tweaking, so here’s a quickstart guide based on what I discovered along the way. First of all, follow Atlassian’s guide to create a copy of Hubot. This will download the source code including the HipChat adapter. $ npm install -g yo generator-hubot $ mkdir myhubot $ cd myhubot $ yo hubot --adapter hipchat Answer the questions, and you’ve got a basic bot conf..
If this look like the org. chart of the place you work at, you might want to consider thinking to go somewhere else.  No organisation ever started to end up like this, but it usually happen when you do not ingrain a culture of learning into your people and your organisation. This happen when you put people who are just about the how, without understanding the why. The moment people stop caring where the company is going, and just care about..

Doing kata - dimitarsimeonov.com - 10 years ago - eng
In karate practice we train by performing a predefined sequences of actions, called “kata”. These include blocks, strikes, stances and jumps in a strictly defined sequence. Throughout the kata, every body part has an exact purpose. The legs do stances and kicks. The arms and forearms - blocks an punches. Even the smallest parts of the body have a part. The eyes need to look in the direction of the technique, the feet need to “grab” the fl....

When we face choice and say “Yes, I will do that. I am that kind of person,” we use our identity to justify our choice of action. The choice might not be the most convenient, but it matches our preconception of who we are. When we decide whether to make our bed in the morning, whether to drive above the speed limit, whether to drink coffee or take a nap when tired, our identity has a say in the decision. If we consider ourselves tidy, we’....

Everyone who writes for a living will eventually write about themselves. It's almost a natural law. Heck, someone else has probably thought of a name for it. (Hint: it starts with an 'N'.)So why this piece?
At Jane Street, we have always been heavy users of pre-processors, first with camlp4 and now ppx. Pre-processing makes the infrastructure a bit more complex, but it save us a lot of time by taking care of a lot of tedious boilerplate code and in some case makes the code a bit prettier.

Ever forgotten to add a critical service to monitoring?

Me: Why is this report different to the one in production? SysAdmin: Dunno. I guess they must have fixed it production and forgot to check it back into source control. If I had a dollar for every time I’ve had that conversation I’d be a rich man. It is usually the result of some late-night troubleshooting and finally the system is working as expected and everyone goes to bed. But the next day, nobody remembers what exactly they changed..

I find it fervently infuriating when someone uses the word passion and degrades it. They degrade the meaning of the word. Passion is the ultimate upgrade of the hobby, a cultivated curiosity. Something you're currently dedicating your life to. You diminish it when blurting that a person that doesn't spend any time outside the "obligatory work hours" on his passion, not even a thought, to be passionate. What is passion if it's not thinking a..
At Cerner, we love Ruby and Rails and use it prominently in our cloud based solutions. When we found out RailsConf 2016 was going to be held in the hometown of Cerner’s headquarters in Kansas City, Missouri, we were excited for the opportunity to support the conference by attending as well as being a sponsor and hosting one of the official after parties. RailsConf 2016 took place in the heart of downtown Kansas City.
This is the story of my involvement with Fine Uploader, how it changed my life, how it affected those around me and my peers at Widen, and how I hope it can continue to have a positive net effect on the open source community and individual developers.
This post for Smashing Magazine looks at one of the most popular image effects, grayscale, to compare its implementation in HTML canvas, SVG, CSS filters, and CSS blend modes.
Today I turn 31. Before the day is through, I'll have ended up celebrating with family and coworkers. And Bash, because as it turns out, Bash can be a bit festive. I find most default Bash prompts to be rather boring. Sure, they vary from platform to platform, but they all seem a little too lite on info that I care about. A few years ago I decided to liven it up a bit.
In high school I did well in math competitions and even qualified for the national team. Part of the reason was that I spend a bunch of time on my own solving math problems. It didn’t feel like a compulsory work. Instead, it was often a compulsive behavior for me. I was often unable to un-glue myself from the math problem at hand. When I saw a good problem, I attempted to solve it. The easier ones I could solve quickly. But some of them....
I’m just going to jump right into the definitions and rigor, so if you haven’t read the previous post motivating the singular value decomposition, go back and do that first.

Some of the wifi routers (especially beetel models) provided by airtel broadband is paired with two SSIDs(Access point), One is an actual SSID for internet access and another one called MGMNT, which is used by airtel for maintenance / automatic configuration. The default key for MGMNT is 0987654321, which is hard-coded into the router’s firmware and the stupidest part is there is no option to disable it. Now lets start hacking!, Con....

I was just getting in my terminal when I noticed that the cursor was not blinking. C’moon! I can work with a non-blinking cursor. When a cursor blinks it sets up the pace. I keep moving as the cursor blinks. It is hypnotizing. I can leave my thoughts behind and operate in a state of flow. The blinking cursor is easy to see. I don’t need to look for the white rectangle. I can spot it much easier even when I’m not focused on the screen. I....

Introduction If you are new to Linux or the Mac you might find installing Go to be a bit confusing. It was for me when I started learning Go. Go was the reason I stopped using Windows, which I used for 20 years. Even if you’re experienced with these operation systems, setting up Go might seem a bit of a mystery. With this in mind, let’s walk through installing Go.
