Why would I want to work at a large company?

Filed under: Life,Navel Gazing — Cranky Sysadmin @ 6:45 pm

About a year ago, I made the switch from startup hopping to working for a large company. While I may not stay forever, it seems like a good choice so far. I work for Philips HSDP in Cambridge MA. If you’re interested in my reflections on working for a big company, read on.
The good and the bad!

Developing Node in Emacs on Ubuntu

Filed under: Uncategorized — Cranky Sysadmin @ 8:00 am

I am impressed by my first impressions of node.js. It feels very Unix-like. If you want to develop node in emacs, a good place to start might be Truong TX blog. My setup differs a bit from his. You can find my whole emacs environment on github. Outside of emacs, you of course should have node and npm installed. I then installed Tern with ‘npm install tern -g’. The relevant snip from my emacs init is below

;; if you aren't running a package manager, you'll need to
;; require js2-mode, ac-js2-mode, tern-mode, tern-auto-complete
;; javascript using js2-mode and tern
(add-hook 'js2-mode-hook 'ac-js2-mode)
(add-hook 'js2-mode-hook (lambda() (tern-mode t)))
;; I have tern in a non-standard directory
(setq tern-command '("/home/FOOFOO/node/bin/node" "/home/FOOFOO/.node_modules/bin/tern"))
(eval-after-load 'tern
 (require 'tern-auto-complete)
(add-to-list 'auto-mode-alist '("\\.json\\'" . js2-mode))
(add-to-list 'auto-mode-alist '("\\.js\\'" . js2-mode))
;; if you don't want to warn on missing semicolons,
;; uncomment the following
;; (setq js2-strict-missing-semi-warning t)

I don't know why I never used yasnippet before, but I've been wasting a lot of time without it. Add the following above any auto-complete sections:
(require 'yasnippet)
(yas-global-mode 1)

And with that, you should be able to settle into some nice node tutorials.

What is this nodejs Thing You Speak of?

Filed under: Programming — Cranky Sysadmin @ 7:19 am

A very long time ago, I was interested in exposing javascript via apache in much the same way as mod_perl does. I got a working demo running based on (now dead) mod_snake code and the mozilla spidermonkey javascript engine. I abandoned the project due to other interests, but I still like the idea of serverside javascript. Now there is nodejs, which is a javascript engine based on the v8 engine. It has a reasonably complete standard library, and a nice package manager called npm. There is even a (old outdated) mod_node if you really want to hook it into apache. Node looks like it’s architected well and has good performance. If I were to judge a book by its cover I’d say node is worth learning and using.

The Best Advice I Ever Received

Filed under: Life — Cranky Sysadmin @ 8:17 am

By quantity, my parents have probably given me the most good advice, but the most useful piece of advice was given to me over a game of chess with my English teacher, Mr. Matkowski. I had made some placeholder move. He shook his head and said to me, “Don’t do chicken shit moves”. That was 30 years ago and every time I do a chicken shit move, I still hear his disapproving voice in my head. I need to find him and thank him some day.

Rust and Project Euler

Filed under: Programming — Cranky Sysadmin @ 8:54 pm

I stumbled across a neat language called Rust recently.  What makes it interesting to me is that it’s billed as a replacement for C that is type safe and memory safe without a garbage collector. Rust has been ported to Arm Cortex M4 and the lack of mandatory garbage collector means that it should run well on constrained systems. Apparently it also has a good concurrency model, but I don’t know much about that yet. I also recently discovered Project Euler, which is a bunch of curated math problems. Well, now I’ve started solving the Project Euler problems in rust. If you’re interested, you can find the few problems that I’ve solved so far on github. They’re probably not ideal solutions since I’m not an expert at math, rust, or efficient algorithms, but one has to start somewhere.

Roped In

At our last meeting, the Pentucket Radio Association elected me to the position of president. I hope that I can represent them well.

The club participates in several events during the year and ultimately, I’ll be responsible for their success. Like many other local clubs, we have some recruitment and outreach challenges and I will need to attend to those as well. I’ll blog about the more interesting public facing stuff, names excluded to protect the innocent.
