Hark: The Software Paradox

Stephen O'Grady at RedMonk has launched a new Podcast called Hark. In his second episode, he and Agile programming guru Kent Beck have a thoughtful discussion around the ideas in O'Grady's book "The Software Paradox."  Even though software is "eating the world" and become more widespread and strategic, its economic value appears to be declining rapidly. Certainly, we've seen a shift in the …

Technology for the Non-Technical

I am potentially one of the least technical people in my generation. I’m 30 and I am afraid of my cellphone, my laptop, Netflix, the microwave…. Okay, afraid is maybe a strong word, but baffled by them at the very least.

In high school, while my classmates wrote most of their papers and assignments on the computer, I insisted on writing everything out by hand and only typed it out afterwards if absolutely required. It wasn’t that I had issues with typing – my mom who worked as an administrator for many years made sure that I learned to type from a very young age and I type quickly with a reasonable amount of accuracy. I just felt that writing by hand kept me more “connected” to the words I penned. Simply, my name is Sarah and I am a Luddite.

After high school I studied journalism for a couple of years and then entered the workforce into a number of different jobs, such as in sales and marketing and it became necessary …

Learn to stop using shiny new things and love MySQL

A good portion of the startups I meet and advise want to use the newest, hottest technology to build something that’s cool, but not technologically groundbreaking. I have yet to meet a startup building a time machine, teleporter or quantum social network that would actually require some amazing new tech. They have awesome new ideas with down-to-earth technical requirements, so I kept wondering why they choose this shiny (and risky) new stuff when all they need is a good ol’ trustworthy database. I think it’s because many assume that building the latest and greatest needs the latest and greatest!

It turns out that’s only one of three bad reasons (traps) why people go for the shiny and new. Reason two is people mistakenly assume older stuff is slow, not feature rich or won’t scale. “MySQL is sluggish,” they say. “Java is slow,” I’ve heard. “Python won’t scale,” they claim. None of it’s true.

sed tricks

I helped a charity to rebuild a MySQL server and to restore a database with a lot of data of longblob type in the last two days. Fortunately there was a dump backup file for the database in question.

However, tables with longblob column(s) were not defined with “ROW_FORMAT=COMPRESSED”. I’d like to restore that database with row compression before inserting the data. Therefore I need to modify the dump sql file. The problem is that the file is 2.5 GB and the server only has 4 GB memory. So editing it is a challenge. Fortunately, Linux has sed to save the day. Don’t you love open source free software?

I am power Vi/Vim user, so I am familiar with sed and have used it in the past. But there are still a few things that I searched around for quick answers. So I’ll record noteworthy points here. I couldn’t remember how many times my own past blog entries helped me over the years. And I hope you’ll find this helpful too! …

Setting up WordPress on Debian/Ubuntu running Tengine web server

I will change my host provider within a month. I’ve been using Midphase for several years and have decided to use Linode as my next virtual private service provider. I will move this site there in the next few weeks. This will be my first time moving a domain and I hope the transfer will be smooth without too much down time. After all, I know my readers worldwide are hanging on to every word I type and deserve a site that runs 24 by 7

Since I will have total control of this host, I decided to use Tengine, a great fork of the Nginx web/proxy server. Here is my note on how to compile and config Tengine on Debian/Ubuntu, and then setup WordPress. During my study and testing, the following sites are pretty helpful.

Cloud Outages Keeping Your Application Down? It Doesn’t Have To!

We’ve all been through downtime at some point and deplore the lost work and productivity that comes with it. And the only thing worse than server downtime is having to report that downtime to frustrated customers who are depending on your service for their business.

Yesterday, AWS server issues meant downtime for highly trafficked sites Instagram, Vine, Airbnb, and IFTTTA. According to AWS’s health dashboard, the company’s North Virginia data center may be to blame.

The fact is, any cloud system is subject to outages, from Yahoo Mail to Microsoft BPOS and VMware; however, outages aren’t and shouldn’t be business as normal.

While we never wish for anyone to experience downtime, when stories like AWS hit the …
