From HBR's 9 Productivity Tips from People Who Write About Productivity : Block time away from reactive tasks (email). Business = wasted energy. Exercise, sleep, and 90 minute work bursts. Incomplete tasks prompt healthy thinking out of context. Time off or stepping back is invaluable. Genuinely help were most successful/enjoyable. Plan for saying no while highlighting priority and seeking feedback. Measure important behavior change. Mak..

2015 was an interesting year, and one that I really enjoyed! I spent a lot of time getting/restoring/playing the last few arcade machines that I’ve wanted in my arcade collection - I just love the retro arcade hobby! As a result, I won’t be getting or restoring any more in 2016 at all (I have a few arcades that I want to work on to upgrade, but that’s about it). I’ll be spending most of my time playing them!

I find during the holiday season many pick up new books , learn a new language , or brush up on some other skill in general. Here’s my contribution to hopefully giving you a few new things to learn about Postgres and ideally utilize in the new year. It’s not in a top 10 list as much as 10 tips and tricks you should be aware of as when you need them they become incredibly handy. But, first a shameless plug if you find any of the following ....

A month or so ago I started collection emails on searchcode.com to determine if there was enough interest in a downloadable version of searchcode. The results were overwhelmingly positive. The email list grew far beyond what I would have expected, and this was in the first month. As such I have been working in this downloadable version of searchcode which will probably be called searchcode server. Progress has been reasonably straight for..

Friday 21:15 Fifteen minutes after the theme announcement, my friend Ben Homan walks through my front door. Not really my front door, I'm just a subletter. But this is a first. Normally he ignores our instructions to walk in without knocking. The first time, he texted me from the driveway. 21:30 Jesse Kooner walks in, also unannounced, bearing frozen pizza. Before he can even kick his shoes off, I loudly explain the theme: a never-b..

Daniel P. Berrangé wrote about trying out a single node ceph cluster. I decided to take his article and turn it into an Oh-My-Vagrant omv.yaml file. It took me about two minutes to do so, and two hours to debug a problem caused by something I had broken on my laptop. If you’d like to replicate his article in less than 5 minutes, pull down the omv.yaml file that I’ve just published and run omv up. Here’s the full terminal output of my s..

Here’s a bit of folklore I often hear (and retell) that’s somewhere between a joke and deep wisdom: if you’re doing a software interview that involves some algorithms problem that seems hard, your best bet is to use hash tables. More succinctly put: Google loves hash tables. As someone with a passion for math and theoretical CS, it’s kind of silly and reductionist. But if you actually work with terabytes of data that can’t fit on a single m..

Volatile and atomic variables are an important feature in Java language. Especially when dealing with multi threading . A simple incrementation algorithm works fine in a single threaded program, but won’t work as expected in a multi threaded system: private int counter = 0; public int increment(int i) { return i++; } This code will work correctly in a single threaded program, but will give incorrect results in case of a multi threaded ..

The headline of Postgres 9.5 is undoubtedly: Insert… on conflict do nothing/update or more commonly known as Upsert or Merge. This removes one of the last remaining features which other databases had over Postgres. Sure we’ll take a look at it, but first let’s browse through some of the other features you can look forward to when Postgres 9.5 lands: Grouping sets, cube, rollup Pivoting in Postgres has sort of been possible as has ....

I’ve been wanting to write this for a long time, just to clarify my thoughts on the subject. Now, on vacations, I took a couple of days and finally did it. This is a personal opinion based on my personal experience and tons of books I have read, and I am not, by any means, the supreme holder of the truth, so you will probably disagree with me at some point.

I recall extremely early stage where you’d build a feature, realize it was awesome, then the next day write a blog post for it. At some point you start to move from that to more coordinated launches. A larger coordinated launch allows you to reach a bigger audience, can lead to bigger deals, and help expand your overall market. But perhaps more importantly by the time you hit full launch you’ve message tested and ensured it’s going to reson....

Because of the fact that I personally work for an ad supported company and that searchcode.com is currently supported via third party advertising I tend to keep an eye on the state of ad blockers on the web. Most people probably know about adblockplus and other browser extensions however there are other ways to block ad’s on ones network. One that I had previously read about was setting up your own Bind9 server on a server and adding cust..

The Indian startup ecosystem has taken shape and exploded in the last few years, and so have the countless stories surrounding them. Unsurprisingly, lessons of unsuccessful ideas and attempts haven’t gotten as much precedence as successful counterparts.

Packages in Java is a quite simple and straightforward concept of the language. It’s there from the beginning and it’s commonly used by every Java programmer. In a few words, these are the rules you have to follow to create a class inside a package (spoiler: which are not completely true, as we’ll see later): Package statement must be the first one specified in a java class file A package namespace must match the physical path of the file....

In reply to Joaquin. Exactly, this is the right observation to define the sequence that the author implies. I was confused because the values listed on the book didn't make it that obvious to me that this is the right definition.

Now i may be wrong but i think you went completly overboard. If you observe the difference between subsequent numbers of the sequence, youll notice that the numbers missing are the ones on the sequence. 1 3 7 12 18 26 35 45 56 69 2 4 5 6 8 9 10 11 13 The seuqence adds the enxt number with n+1 but it checks to see if that number exists in the sequence if it is go to next number if not add that number. so the next number wo..
