While neither a fan of DROdio’s website or the author’s writing style, Dissecting Coin’s Massively Successful Product Launch nevertheless gives me a way in to talk about Coin once again. Last month, shortly after Coin launched to great fanfare, I condensed some of my thoughts into a post titled Thoughts Regarding Coin . I explained the device’s premise, areas I thought it would excel, and those in which I felt it would fail or needed..

After 3 weeks, I’m actually leaning slightly more towards the mini if I had to pick one. Though I do work a lot from my iPad, the iPad is not my main work machine. I still spend most of my time at my desk working from my MacBook Air. And so, for the things I do use an iPad for, the iPad mini is better for about 80-percent of them and ‘good enough’ for the other 20-percent. I plan to keep using both iPads, side by side, for at least another ..

I love overachievers in the world of cars much more than in person, hence my unbridled enthusiasm when I happened across Mercedes’ six-wheeled monster the G63 AMG and Ghe-O’s indomitable Rescue. Something about these trucks , for their rugged ability to tackle literally any terrain imaginable truly epitomizes the colloquial definition of the term 1 , awakens a visceral desire to pack my backpack and spend a long weekend trekking throug....

I’ve previously talked about the idea of shifting from estimates to budgets. The fundamental point of this article is that it’s more useful to control costs than to predict costs. The problem of this argument is whether it’s possible to develop software in that way. How will the relationship between the developer (or supplier organization) and the customer (or the customer organization) have to change? Is this a chance we’re able to make?

The following I posted on Quora in response to the question “I am planning to make a small scale search engine on my local system, but I don’t know from where to start?” . It’s a reasonable answer so like my Mahalo one I thought I would make a copy for myself. I agree with Wolf Garbe and that you are better off in your case starting with existing technologies, have a look at http://yacy.net/ and SphinxSearch as well. However if you a..

Towards the end of Amazon and the Benefits of Vision Ben Thompson explained the importance of vision — and the consequences of a deficiency in this department — using many of today’s top tech companies as examples. At that point not particularly interested in Amazon’s alleged plans slated for years down the road,, I found this all too brief examination much more fascinating than his actual topic. And then I read an article by Kevin Roo..

In Java, I like to wrap ID values in objects, rather than just passing them around the code as their native "int" or "long" or "String" values. The reasons are twofold why using an object is better: Code becomes more readable, for example foo(LoginId x) is more readable than foo(long x). (Although perhaps neither foo nor x are good names, so perhaps the example over-exaggerates this improvement.) The compiler can do more checking. I..

UPDATE: Migrated from a post I wrote when working on leve.rs The last post I wrote provided examples of different ways to use array manipulation in PHP Link . An amazing number of people replied with a compelling argument, saying it’s better to use a foreach statement instead of the array_walk function. As all comments I receive from my articles, I thought hard on the idea. What is the fastest way achieve the end result?

Starting with November month, I have decided to take a different approach to posting links to cabins I find inspiring, attractive, or otherwise worthy of note: rather than make an individual post each time I come upon such a structure, from here on out I will hold them for the end of the month when I can collect my favorite posts and pictures. This will not only reduce the volume of “Wow.” and “Beautiful.” one-word link posts I have made a ..

When news of a new currency dubbed “Bitcoin” first began circulating, I paid little attention: it seemed like a fad, something no one would remember in a month or two. Instead of fading away though, Bitcoin continued to gain popularity until not a day went by without someone writing an article either glorifying the currency for its upsides or crucifying it for any number of perceived downsides, whether real or not. An interesting parallel c..

cell flash cache read hits vs. cell writes to flash cache statistics on Exadata

When the Smart Flash Cache was introduced in Exadata, it was caching reads only. So there were only read “optimization” statistics like cell flash cache read hits and physical read requests/bytes optimized in V$SESSTAT and V$SYSSTAT (the former accounted for the read IO requests that got its data from the flash cache and the latter ones accounted the disk IOs avoided both thanks to the flash cache and storage indexes). So if you wante....

We are officially code frozen so only critical bug fixes should be resolved until the actual release. The very last feature to make it in is support for Google Play Ads on iOS/Android. We currently only work with the Admob SDK as we move along we might add additional options. To enable mobile ads just create an ad unit in Admob’s website, you should end up with the key similar to this:

Update 2019-07-17: I have released a follow up post Go Binary Sizes Are Relatively Stable which speaks on what's happened in the time since this was published. Note: This is not intended as a "Go Sucks" post. I love Go. I am not saying the developers are lazy or dumb or any of the things Reddit has implied. I am not implying I could build a better compiler. Rob Pike and the Go team are geniuses whom I look up to. The tone o....

Using LinqPad to query Azure Diagnostics (Best WAD viewing client for Devs imo)

Hi All, Really quick and simple post. In a normal windows azure cloud service you get all your lovely eventlogs put into table storage for you to use when diagnosing issues. Unfortunately that can be a bit daunting as there isn’t, or I didn’t think there was, a handy client to view them all in. With the AzureTableStorage driver for LinqPad I can quickly write complex and simple queries to integrate all the WAD logs and I get lovely in..

I’ve been using a Kindle for a long time now, and I love it. But I keep buying paper books. Lots of them. Actually I buy a lot more books than ebooks and it doesn’t even stop there. Admittedly, I am guilty of repeatedly buying paper editions of ebooks I’ve read on the Kindle. For a very long time I’ve not been able to tell the precise reason why I keep going back to traditional books. It’s not about the reading experience or the sexines..

Earlier this year Thoughtworks launched an internal contest offering a prize for the best data-related project created in 30 days. There was no restriction on exactly what could be produced, but the winning entry needed to be impactful, technically interesting, and useful. The best entries combined analytics, data mining and visualization and not only showed something cool, but made you think "aha" too.

Doug Stephens, aka ‘The Retail Prophet,’ gave a compelling talk at the 2013 Online Retailer Conference in Australia on the store of the future. Doug is a retail futurist and shared his thoughts on the transformations he envisages for bricks and mortar spaces. Doug describes the current state of retail as "the most remarkable period in the history of consumerism." It is perhaps the first time ever that the reach of technology exceeds that o..

For a while I’ve been meaning to do some more advanced posts on optimization problems of all flavors. One technique that comes up over and over again is Lagrange multipliers, so this post is going to be a leisurely reminder of that technique. I often forget how to do these basic calculus-type things, so it’s good practice. We will assume something about the reader’s knowledge, but it’s a short list: know how to operate with vectors and the ..
