Can a laptop from 2012 be a viable home server?

from ./techtipsy [alt+shift+b] in technology

over a year ago
I’m a man of many ideas. It’s a shame that most of them are quite stupid. This is one of them, but at least it makes for a fun experiment. Intro After adding an UPS to accompany my server, my setup was as complete as it could reasonably be. The server is low power, but packs...

Ever heard someone say “It’s only software/money/<trivial thing>, not life or death”, in the context of incidents at your company? Although mostly true, I want to talk about a time in my career when sometimes, just sometimes, it was the latter, and how it shaped my approach to...

How to compile HAProxy from source and setup a basic configuration

from Louwrentius [alt+shift+b] in technology

To learn more about HAProxy I decided to compile it from source and use it to load-balance traffic to louwrentius.com across two different web servers. I run HAProxy on a VPS based on Ubuntu 12.04 LTS. Let's dive right in. First, we need to download the source. Don't copy/pased...

Matthieu asks: Since you do a lot of things (investor, dad, owner of a "small" business, blog writer) I was wondering what you don't do to keep up with this level of commitment. In the same line, it often said that behind one person success, there's a wife/husband that helps to...

Hanlon's razor is a classic aphorism I'm sure you have heard before: Never attribute to malice that which can be adequately explained by stupidity. I've found that neither malice nor stupidity is the most common reason when you don't understand why something is in a certain way.

If you ask someone to think of a battery, they’re probably going to picture a chemical battery, like a AA alkaline or a rechargeable lithium-ion battery. But there are other kinds of batteries that store energy without any fancy chemistry at all. If you find a way to save energy...

When Google killed Google Reader, the bloggosphere took a severe hit and the content quality went down because there weren't enough readers to justify the effort it takes to maintain a high quality blog.

What's left is a decaying wasteland of blogs, most abandoned, a lot are now SEO spam, and 99% are not worth reading. BoredReading is a way to read the remaining great blogs that survived the ice age.

To add your favorite blog, please suggest it here! I get emails every day which helps me maintain a high quality selection of blogs!
