  Fun With Numbers

Yesterday the NPD Group issued a report on U.S. tablet sales in the U.S., from January through October of 2011. Worth noting up front is that the numbers in this report are about sales — actual tablets sold to actual customers — not “shipments” from the factory to stores and warehouses.Much-reported on is that second-place went to HP, after its fire sale on the discontinued TouchPad. What hasn’t gotten much commentary is the extraordinarily contort...

  Handle NXDomain error when resolving IP address in Ruby DNS resolver

In another post, we covered how to resolve SystemStackError when resolving IP address in Ruby. In this post, we would cover another common issue where a NXDomain error is returned when resolving an IP address. The NXDomain error means that the queried domain name does not exist in the DNS. In Ruby, DNS resolver library will use /etc/resolv.conf by default get the name servers to resolve the domain name. There are multiple DNS name servers can be specified in /etc/resolv.conf with below format. ...

  What can CSS :has pseudo class be used for?

CSS's :has is a pseudo-class representing an element if any of the selectors passed as parameters matching at least one element. From the name, it's also easy to understand how it matches elements. The syntax is pretty easy as well: :has([some-selector]) With this pseudo class, it can do lots of things which previously would be challenging or need tweaking the DOM elements with JavaScript. This post will demonstrate what :has can be used for. Introduction Below are a few simple ex...

  Java 9 release is delayed again

The original Java 9 planned release date is March 2017. But latest source shows that Java 9 release will be delayed again to July 2017. It's four months later than the planned date. Oracle Chief Architect of Java Platform group Mark Reinhold proposes this new release date in a message sent on the OpenJDK mailing list.  Despite this progress, at this point it's clear that Jigsaw needs more time. We recently received critical feedback that motivated a redesign of the module ...

  JavaScript is now a necessity

I've long looked at JavaScript as a second-class citizen in the programming world. Early on, it was the source of numerous security problems; it was a nice bit of glue to patch together HTML applications with a bit of styling, but nobody would use it for serious code; and so forth. Java, Ruby, Python, they were the languages for doing real work. But my attitude toward JavaScript has changed completely in the past few years. JavaScript has "grown up." I'm sure there are many JavaScript dev...

  Programming Languages for Machine Learning Implementations

Machine learning algorithms have a much better chance of being widely adopted if they are implemented in some easy-to-use code. There are several important concerns associated with machine learning which stress programming languages on the ease-of-use vs. speed frontier.Speed The rate at which data sources are growing seems to be outstripping the rate at which computational power is growing, so it is important that we be able to eak out every bit of computational power. Garbage collected la...

  Redesigning the Technical Hiring Process

Since my last post on technical interviews, I’ve been fairly involved in hiring at Pulse as we grew our team from 6 people when I joined last November to 14 full-timers. In my previous post, I suggested that technical interviews, in the conventional sense, are not especially effective (by technical interviews, I mean the traditional 45 minute coding-at-a-whiteboard and algorithm puzzlers interviews). Those do a great job of telling you how well a candidate is at acing those types o...

  OpenLDAP Proxy -- rwm-map vs map

OpenLDAP proxy is used to proxy ldap request and response between clients and servers, different servers may have different representations/attributes to mean the same thing. For example, in one LDAP server, the firstName may be represented by firstName, it may be represented by givenName in a different server. However, from the client perspective, it only wants to get the firstName, it doesn't care about the backend attributes. In this case, attribute mapping can help provide a virtual view of ...

  For Google CEO Larry Page, a Difficult Premiere Role

When Google Inc. co-founder Larry Page announced that he would take over as chief executive earlier this year, he promised that he would shake up the Internet search giant to speed up decision making. Instead, much of the shaking up has happened to the new CEO.Challenges have piled up for Mr. Page since he assumed his post in April. They include a broad U.S. antitrust probe of the company's practices; the settlement of a long-running criminal investigation into Google's adver...
