Migrating from Blogger (Google) to WordPress July 13, 2012

With the sketchy nature of Google, I’m starting to decrease as many dependencies as I can from them. Starting with my blog. A part of it is just a technical test to find out how hard it would be to wean off of the free service.

Overall, there’s few – if any alternatives to WordPress that will let you import your blog from Blogger with such success. There are a few caveats I feel are worth mentioning, however…

Worthy of distribution: Your cell phone records July 2, 2012

This is just too cool, and too perfect a testament for how you can derive a lot through data and social networking.

Via the F-Secure labs blog: http://www.zeit.de/datenschutz/malte-spitz-data-retention

Shows an extremely well put together example of combining a tidbit of privileged information with social networking and how this truly is a brave new world.

Map has it all.

NoSQL: stretttcch – pop! May 11, 2012

You know the noise you hear when something is stretched close to it’s breaking point, like a balloon? In the context of the NoSQL bandwagon bubble: here’s some of that noise.
A detailed account of jumping on a bandwagon with an immature scene of products.

Although admittedly I have my eye on MongoDB, I still can’t believe the utter lack of ACL control these “databases”/”document stores” have. Tisk!

Another factoid: Netflix uses NoSQL… and most of their data in it is Tomcat logs.

If you’re not off of Godaddy yet … December 23, 2011

You should be. The Godaddy girls are stupid. The commercials are worse. Bob Parsons is kinda creepy (not just the elephant thing). The ads are terrible. The site is terrible.

Do you need another excuse to move your registrar needs to another company such as Gandi or Namecheap?

You need another excuse? here it is.

You should know what SOPA  * is about between the lines. (Job growth? Puh-leese, the job growth from the .com boom didn’t need SOPA thank you very much!)

Over the last few months I’ve moved a dozen domains off of Godaddy on to others (client’s discretion).
If you’re still on the fence, there’s a pretty good run down of good alternative registrars on this blog post.

ICANN also has a full (but impersonal) list of accredited registrars as well.

PS: Namecheap has a coupon code for a little bit off “SOPASUCKS”.

Browser wars: Feels old school March 3, 2011

Stepping back from your browser of choice; it just hit me how HTML5 has reignited the browser war, pushing innovation and making things feel old school again.

There’s nothing ‘old school’ about HTML5, or is there? Anyone remember the old dx filters in IE? rotate, flame text, etc – now it’s all about standards, but HTML will no longer have a ‘version’ number. To be frank, this scares me – I think it will end up harming innovation. Certain majority players see fit to implement what they want. Without a marketing slogan to drive for – I smell another recession of lame-duck browsers.

What IS old school is a familiar aura with each contender putting up an HTML5 demo page to show what it’s got (details start with this slashdot post.) to me this has a good, old-fashioned competitive feel that I think will decline like a hot rock once the initial “HTML5” support buzz has passed. I hope I’m wrong.

On top – Worthy of distribution February 25, 2011

No really, this post is about top. I’ve always fancied myself well versed in top; every once and a while I need a reminder. Here’s a pretty cool/well presented in-depth rundown on how powerful this utility really is for people in charge of inspecting system behavior.

View in HD here!

Some more things to add:

Also to add something that is really useful I feel was left out that’s pretty important: “Shift + <", "Shift + >” will move the sort-by in the direction of the ‘arrows’. Oh, and ‘shift-w’ to ‘save’ these settings to .toprc :P.
‘x’ will toggle highlighting the column currently sorted by, coupled with the above, you can easily move through different consumptions.

On: ntp, ntpd. link dump! January 14, 2011

So, in order to quickly have a (debian) machine up and running on ntp, you’re bound to do something like this ‘apt-get install ntp ntpdate’.

The problem is that this installs ‘ntpd’ too. The default configuration is to allow your server to answer to NTP queries from anywhere.

If you want to give the crackdown you’ll be somewhat frustrated with pre 4.6 config options as they’re somewhat nontraditional to what we usually see; without further ado, here’s a simple ‘link dump’ for a configuration guide.

On ntp 4.x? Guess what? Doesn’t work =[ – must be done with iptables.


Here’s the cheatsheet /etc/ntp.conf :

driftfile /var/lib/ntp/ntp.drift
server my.server.address


restrict default ignore
restrict -6 default ignore

restrict 127.0.0.1

restrict my.server.address

This will allow you to poll things, e.g.: ntpq -p; and keep everyone else from sending packets to your box either on purpose or by accident. Note: You -have- to have your ‘servers’ in restrict lines or else it’ll hang on the first poll. (Indicated by ntpq -p )

When ntp isn’t working right, this is what ntpq -p looks like:

 box:/etc# ntpq -p
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================

123.123.123.123  .INIT.          16 –    –   64    0    0.000    0.000   0.000

Note the 0.000’s in the delay/offset/jitter – it’s also stuck on the sync request at INIT.

A properly functioning ntpq -p should look something like this:

box:/etc# ntpq -p
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================

123.123.123.123  123.12.1.12      3 u    3   64    1    1.349  2446.01   0.000

Worthy of distribution – Why do enterprise applications suck? December 27, 2010

Take it to the next step March 14, 2010

Very cool (albeit somehow hectic page) on pythian on a recent Rasmus session.

There’s a HUGE amount of information in this for people wanting to ‘step to the next level’ with web application development. You’ll have to turn over some stones of your own and reapply some of this to you independent scenario, but still a wealth of info!
