Submission + - lineinfile be damned (chrisshort.net)

oaf357 writes: The Ansible lineinfile module is designed to search a file for a line, and ensure that it is present or absent. lineinfile is very effective at that particular task. However, when the line has to be in a certain place or before or after a certain line, lineinfile becomes a hassle to manage. Most people on IRC (#ansible) tend to agree, lineinfile is not a very good module in practice. Even Brain Coca says to avoid the lineinfile module. But, there is one use case I have found where line in file really excels.

Submission + - Technical Debt and the Ongoing Battle Against It (chrisshort.net)

oaf357 writes: I have been trying to fit a lot of square pegs into round holes lately. Eliminating technical debt with modern day DevOps practices to reduce costs is seldom fun or glamorous but is very often beneficial. Reducing costs should be the mindset of IT and one surefire way to do that is to spend the right amount of time on a task to complete it successfully. Finding that balance is definitely tricky especially when a lot of us are human time division multiplexers now. But, that right combination of good work and adequate time spent is definitely out there.

Submission + - What Does Yahoo's Downfall Teach Us? (chrisshort.net)

oaf357 writes: What does Yahoo's downfall teach us? That you must bring together a great team. The assembled players have to push people to build great features (the content will come, as exemplified by Medium, Snapchat, Facebook, etc.). That team must also do its due diligence in an effort to add value to the company. Now we all get to see how Verizon will deal with Yahoo assuming that deal gets approved, of course.

Interestingly, as a tier-2/regional operator, these cache devices are hard to get because they fill a certain role. We have worked with Netflix to try and get the caching device, and it just doesn't do any good if you have less than 3-4gbps of pure Netflix traffic. It does not work because the caches have to ... populate the cache! They do this regularly, and the do it overnight -- but it is an absurd amount of data, especially when there are multiple bitrates. I am told that the cache runs > 1.5gbps to populate, almost nightly. So if you don't push significantly more than that, it is not a cost winner.

As a transit provider/local ISP/bandwidth buyer, 3+gbps is a lot of traffic. We found it mildly more attractive to buy a 10gbps wave to a Netflix-available peering point and peer directly with them than to buy 2+gbps of transit from Level3/Cogent/HE, especially factoring in last mile costs.

Also of note, my own traffic engineering testing shows that Netflix *strongly* prefers Hurricane Electric (as of last fall), then Cogent, then Level3.

There is a really horrible hole between 1gbps and 10gbps of consumption that there isn't a good solution for. Netflix knows about it, but it is a very difficult target to hit -- it may be cheaper to buy transit, or it may not be, but hardware isn't the answer. This same situation exists for all CDNs - limelight, edgecast, akamai, L3.

As usual, peering is the answer. Our customers pay us to bring them Netflix ... so we buy a wave and backhaul it hundreds of miles to satisfy them. It'd be ridiculous for me to charge Netflix when my customers are asking for it!

Or maybe, that JCPenney makes most of its money in its brick-and-mortar stores rather than online?

Or most of their online customers go directly to JCPenney's rather than searching for a source of doodads or widgets?

In the end, google might have done JCPenney's a favor by showing them how little business their SEO games actually brought, and that this is an expense they can well do without...
