Numbers Everyone Should Know. Google AppEngine Numbers This group of numbers is from Brett Slatkin in Building Scalable Web Apps with Google App Engine. Writes are expensive! Datastore is transactional: writes require disk accessDisk access means disk seeksRule of thumb: 10ms for a disk seekSimple math: 1s / 10ms = 100 seeks/sec maximumDepends on:* The size and shape of your data* Doing work in batches (batch puts and gets)Reads are cheap! Reads do not need to be transactional, just consistentData is read from disk once, then it's easily cachedAll subsequent reads come straight from memoryRule of thumb: 250usec for 1MB of data from memorySimple math: 1s / 250usec = 4GB/sec maximum* For a 1MB entity, that's 4000 fetches/secNumbers Miscellaneous This group of numbers is from a presentation Jeff Dean gave at a Engineering All-Hands Meeting at Google.

You're Doing Freemium Wrong. We Recommend These Resources I make a point of trying as many new startup products as I reasonably can. Quite a lot use a freemium model where they offer me some free service and then pester me to upgrade to the $10/month “pro” version. Out of dozens of products I’ve tried over the last couple of years, I’ve upgraded to the pro version approximately three times (Dropbox, Github, Spotify.) Why so few? My basic contention in this post is that in many freemium startups, the free product is the real product and the “pro” product is just a bunch of random tacked-on features that might appeal to power users.
Now I’ve never managed a freemium model myself, so these are just common sense observations. The Wrong Way: Let’s start with some basic logic: 1) Your startup is in business to make as much money as possible [1] 2) The amount of money you make equals (the number of people paying you, i.e. your customers) X ($ per customer) So far, so good. Now the logic behind the freemium model is: Conclusion: Unoconv: Convert between any document format supported by OpenOffice. Unoconv converts between any document format that OpenOffice understands. It uses OpenOffice's UNO bindings for non-interactive conversion of documents. Supported document formats include Open Document Format (.odt), MS Word (.doc), MS Office Open/MS OOXML (.xml), Portable Document Format (.pdf), HTML, XHTML, RTF, Docbook (.xml), and more. Converts between different document formats that OpenOffice understands OpenOffice can export to about 100 different document formats Can be used for batch processing Combines with asciidoc and docbook2odf/xhtml2odt to create PDF or Word (.doc) files Can apply custom style templates during conversion (to enforce corporate identity) Autostarts OpenOffice for processing if necessary Can be used in a client/server environment to process documents centrally Can influence OpenOffice filters during import and export Supports OpenOffice on Linux, Windows and MacOSX OpenOffice (and thus unoconv) support various import and export formats.
How Are You Managing Your Talent? In recent times, performance appraisal has been a subject of intense ideological debates. Performance appraisals have traditionally served as a mechanism to basically assess an individual’s performance in the previous year to reward employees in terms of compensation and career progression in the coming year. On one hand, organizations, at least the reasonably larger ones, need some systematic and transparent way to deal with employee’s performance evaluation. On the other hand, with more part-time and virtual employees entering the workforce on a very mission-based engagement as opposed to building a long-term career, the whole idea of formal performance management systems seems to be rather backdated.
So, what’s the real deal? The discipline of performance management has been relatively recent, and rather controversial. “Ford’s $5 day is often cited as a key factor in expanding the middle class. However, notwithstanding such criticism, another bold experiment was in the offing. How to Hire Geeks, Brand Your Shop and Beat the "Talent Shortage"
As a recruiter of software engineers, I hear every day how difficult it is for software companies to find technical talent. If hiring engineers was easy, I wouldn’t be in business. Using a recruiter is one way to have qualified potential employees neatly packaged and delivered, but there are several other strategies that forward-thinking firms can implement to differentiate themselves from their competitors who are just posting ads to the same old places and hitting up the friends and family networks. Your company probably spends significant amounts of money to advertise your product and brand, but very little attention is paid to promoting the company’s identity as a good employer for engineers. These strategies can take a bit of time and effort, but the rewards are stronger talent at a lesser expense.
Here are a handful of ways to make your company more attractive to new engineering hires. Creative ads, inviting job descriptions, unique process Engineering blogs Always be interviewing. RFC 2396 URI. My Problem With Your Interviews. We Recommend These Resources This article comes right after Facebook rejected me after 3 phone interviews, but it is not going to be a hate-post. In fact, I’ve been planning to write it for a couple of months. But now onto the topic: tech companies (Google, Facebook, VMWare, at least, but certainly many more) are all trying to find the best technical talent. (So they contacted me and asked if I’m interested in “exploring opportunities” with them). But how do they do that? The typical interview (be it a phone screen, or an onsite interview) consists of solving a problem. What you do on these interviews is something you never, ever do in real life: you write code without using any compiler or debugger. Btw, here’s an excerpt from my feedback after my first phone interview with Facebook: On the other hand, I don’t think having 1st year CS homework problems on interviews for senior developers is a great idea.
The problems outlined above are what I don’t like about these types of interviews. A Comprehensive Developer's Guide to Payment Card Industry Compliant Web Apps. We Recommend These Resources When I first started working at CashStar.com three and a half years ago, I had heard about PCI before, but I didn't really know what that meant. Since we were building an ecommerce platform that was going to be accepting credit cards over the internet, I knew we needed to make sure we were fully PCI compliant. We were a startup, we didn't have much money, and any mistake could kill the company. Since I didn't want to be the one to make the mistake, I spent a lot of time doing research on PCI, and what it took to make sure your web application was secure.
The first thing that I did was a simple web search, and I was surprised to find out that there really wasn't much information available. My goal with this blog post is write all of my information down, so that I can hopefully help others through the process, and also to serve as a reminder to me, so that when I need to do this again in the future, I will remember every last detail. What is PCI? Merchant Level. Design Patterns and Refactoring.

There are a variety of ways you can enhance your application with WebDAV access which we will be going into in a latter part of the WebDAV series. For now we will show you how to create a basic online network drive using WebDAV via Milton, a Java WebDAV Server library. Example We will write the logic to create a network drive containing just one file, scratchpad.txt, which can be modified at will from any location where the drive is mounted. You may want to load the project into your IDE so that you can follow along. Step 1: Create The Domain Object This is a simple POJO which will allow us to hold some text and attributes which will nicely represent a virtual scratchpad.txt file.
Your applications could have something similar which would benefit from being exposed though WebDAV. Step 2: Create The Equivalent Resource Class As A Composition In this step, we have created a class with a “has-a” relationship with the original domain object. That’s it!

For more than two thousand years, mathematics has been a part of the human search for understanding.
Mathematical discoveries have come both from the attempt to describe the natural world and from the desire to arrive at a form of inescapable truth from careful reasoning. These remain fruitful and important motivations for mathematical thinking, but in the last century mathematics has been successfully applied to many other aspects of the human world: voting trends in politics, the dating of ancient artifacts, the analysis of automobile traffic patterns, and long-term strategies for the sustainable harvest of deciduous forests, to mention a few. Today, mathematics as a mode of thought and expression is more valuable than ever before.
