Great org mode channel. Thanks Mike!

A collection of random tips for Amazon Web Services (AWS) that I wish I'd been told a few years ago, based on what I've learned by building and deploying various applications on AWS.

Using tumblr like Safari's Read Later.... Hopefully still relevant, looks ok from what i've seen. #ringing_endorsement

Foundation > Bootstrap

I guess it's technically called Zurb Foundation. I also know, not guess, that it helps develop my greenfield apps pretty sweetly without weirdness. They give you the ability to start from a few nice Templates and you build your knowledge and site out from that. It's pretty funny too, that both of these chose horrible search terms for their frameworks.

My history with Bootstrap starts with integrating it within Rails and hoping it all works when i need it to. For instance, and I know I'm not the only one that has this happen to, I've had twitter bootstrap randomly do weird things if i ever go too far off the rails in javascript land. To the point where I'm debugging deep inside the code to find a silly answer and see that it never was meant to do that. Or something else up the stack is breaking this change. I don't even try to go off the rails, i usually like to stick to example code and branch from there.

Foundation hasn't done that to me yet and I'm elbow deep in this one app, thus I'd have experienced it by now in another framework, if it was to creep up.

For instance, dataTables was all wonky for me and was hard enough to grok getting it to work how i wanted in Bootstrap. On this latest app, it was plug and play for the same kind of functionality.

Foundation semantics just makes sense to me. modals are easy as pie and just work. I can use my caveperson approach to html coding and naming and simplistic jqueryscript (hybrid shit i end up writing, as where does one end and another begin?!?!)

The weird about Foundation is why'd they got rid of a lightbox (sugar, but still sugar you need sometimes) only to try and add it back two minor versions later? I mentioned on twitter already, if you went through the pain of upgrading from 5 to 6, and then found out the lightbox you depend on didn't work in 6 (out of the box) I'd be miffed to find that out. Then to hear they got it back on the roadmap to introduce. I guess out of necessity comes innovation, so a foundation based lightbox is on the table for someone bored.

This is weird to me because it shows knee jerk reactions to introducing new shiny things. Sure it's for the better, but reading commits and github comments to figure out a lightbox was no more felt meh to this old bastard. Still I'd rather take that over 'praying it will work' and 'harder to grok' anyday.

Here are some videos for you millenials.

SQL has received some quite impressive updates lately. Modern SQL ain't your grandfathers SQL anymore.

From the same guys as Use the Index, Luke. Seeing this more in my limited circles and looks interesting.

SQL indexing and tuning tutorial for developers. No unnecessary database details—just what developers need to know. Covers all major SQL databases.

from 2010 but still relevant.

Interesting look into using postgres from bash scripts. Must be a use for this or, at least, less of a use on some other framework.

I know i'll need this again, but if your PG starts wigging out check this out. Digital Ocean's default ubuntu is pretty small if your site gets traffic and your DB server starts mucking up, try this first or second after seeing if connections are piling up, actually.

Never heard of this site before but when you are getting a hanging PDF creation from your url based pdf, remember to use unicorn in your development environment. Turns out that any calls to the assets are kind of being blocked by the one creating the pdf. Anyways, multi-process/thread servers will spit out a pdf for you. WickedPDF makes css actually appear, in this app, when compared to PDFKit. Now i can start to style appropriately. peas.

emerge ruby 2.2 instead of using rvm

Blasphamy, i know.

I for once wanted to try a new server with bare metal packages. I feel if I can get this right, when I finally chef or ansible my stack script together, I will win. Tis the hope anyways.

Here is what I did, but I'm open to suggestions on making it better as I feel i could go right to the last line of the following, but wanted to document something that worked at least. As root do (or add sudo)

emerge ruby emerge --autounmask-write ruby:2.2 dispatch-conf emerge ruby:2.2 eselect ruby set ruby22 ruby -v

All should be good. I may have had this autounmask-write stuff due to installing ruby first, which was 2.1 and not what i was after. As an aside i learned about this magical autounmask-write option now so I am thankful.

Hope this helps you, or me, in the future.

Fantastic site. Last post was last year however, but so much good I do hope he comes back. There are Iptable articles and one on finding out the top 10 dirtbags who are trying to get into your system by greping /var/log/messages Keep up the good work!

SaaS application monitoring and analytics. With smart artificial intelligence, you get answers, no alerts!

If you just need AWS cloudwatch monitoring, check these guys out. I chirped them on twitter, as I'm prone to do, and they responded great. I reward companies that are this in touch with social media and their user base. Small ass punk businesses out there can take note too.

It looks pretty and gives you a one page info table with actionable links too. Out of the three I tried, this one works the best out of the box and the next day, with a great UI.

I wonder how fancy this can get, cause with Varnish you can do some pretty funky things.

For instance, and I'll read this link later, but how do you PURGE or bust the cache? I do hope this works, cause that'd be awesome.

Have you ever logged in to a server, ran `free`, seen that a bit of swap is used and wondered what's in there? It's usually not very indicative of anything, or even overly helpful knowing what's in there, mostly it's a curiosity thing. Either way, starting from kernel 2.6.16, we can find out using smaps found in the proc filesystem. I've written a simple bash script which prints out all running processes and their swap usage.

Worked for me to find what was using swap.

Slave to Master - Redis Replication

Thanks to this link I'd just like to report how to turn a slave into a master without losing data, which appears could happen.

h1. Scenario

You have a Master and Slave redis setup. You now want the Slave box to be Master and for this case, you don't care what happens to master; ssh slave@box (meaning, ssh into the slave box) and as the user who can acess redis do:

$> redis-cli redis 127.0.0.1:6379> SLAVEOF NO ONE true redis 127.0.0.1:6379> info .... #should see # Replication role:master connected_slaves:0 .....

Just to put a cap on this, i needed to move from a standalone redis instance to localhost. I replicated redis locally first using SLAVEOF url.blah 6379 and then ran the above bit of SLAVEOF NO ONE worked like a charm.
