Recently we had a bit of an incident with our hot water heater… The tank began leaking. Thankfully it was still under warranty and we got another one for only the cost of labor. Afterward, we ran into another problem. Our dishes began having a cloudy white film on them, and after boiling water (say, for spaghetti) the pot would also have a line of the cloudy white film.

Blockchain is one of those buzzwords everyone is listening nowadays, but what it really is? In this series of posts we will dig one general concepts about BlockChain and a little bit of its relation with BitCoin, as well as we will develop a simple blockchain in Go. To put it simple, and as its name states, it’s just a chain of blocks. The interesting detail is that is a cryptographic chain providing some characteristics that make t....

It's been roughly 5 months since my mu4e email migration . Happy with my choice. Mu4e is awesome. I now have 4 email accounts managed by mu4e, and unfortunately receiving lots of junk mail. I regularly peek at junk folders for false positives and delete junk email permanently. I've been wanting a quick way to glance at junk mail and easily delete page by page. Deleting emails page by page is not supported in mu4e by default. Fortu....


When I delivered my Advanced Oracle SQL Tuning training last week, I jumped into a free-form demo to show that the PARALLEL hints don’t really force anything other than adjusting the cost of parallelizable operations for CBO evaluation as usual. If a serial plan (or branch) still has a lower cost than the respective parallel processing cost, then serial execution would be used there. But when demoing this, I got a surprise.

Last time we covered a bunch of examples utilizing dynamic programming. Again, I recommend you check out that article first before you check this one out otherwise you’re not really gaining too much. Today we will be concluding our section on dynamic programming by discussing its limitations and when not to use it as a strategy.

yahoodevelopers : By Scott Bush, Director, Hadoop Software Engineering, Oath On Tuesday, September 25, we hosted a special day-long Hadoop Contributors Meetup at our Sunnyvale, California campus. Much of the early Hadoop development work started at Yahoo, now part of Oath, and has continued over the past decade. Our campus was the perfect setting for this meetup, as we continue to make Hadoop a priority. More than 80 Hadoop us....



It is not everyday that you get to chat face to face with the creator of a highly relevant open source project. Accordingly, we were highly anticipating a certain visit in mid-October, 2018.

I never would have imagined I would be a part of such an amazing place. Being able to work on technology and help make cartoons kids all of the world love has been awesome. After four and a half years it’s time to say goodbye to friends and co-workers who have taught me so much! I’m thankful for how this place has changed me and the world through our stories and art.

The tech industry is constantly evolving; for better or worse, there’s no way around it. Now, more than ever, having a culture that fosters collaboration, empowers associates, and supports innovation is vital to a company’s success in the face of such constant change. However, an effective culture must be grown organically while being supported by senior leadership. At Cerner, we recognize the challenges involved in growing an effective, re..

Last time we covered the basics of Dynamic Programming. I highly recommend you check out that article first before you check this one out otherwise you might be a bit lost. Today we will be continuing this discussion by revealing a few more examples of Dynamic Programming problems and how to solve them.

Clojure has all the big things to reduce bugs: memory safety, automatic memory management, and others. It also tacks on a few more: immutable by default, managed references, open data types, and others.

Read Part 1 first. Introduction Compared to Jai, Clojure is a straitjacket. It is much more unusable, for sure. Why? Jonathan Blow’s personal style of programming seems to be similar to compression-oriented programming . As such, Jai is designed for it. I like that, so Yao will do the same thing. An example: one cool feature of Jai is the way it is designed to handle the life cycle of code, from straight-line execution, to a sepa..
