Some research I have made recently while working on a broadcasting module of an app. Just saving here some of the best link I have found – as backup and maybe of interest for some people. Obviously if you are looking for a super structured article – I am far from it at this point – but that’s still the filtered version of a few hours of research to find the relevant and usable stuff – and it is practically what I have used to get to the poi..

What’s the point in downloading the app from the store when you can do the same thing in the browser? I’m a product designer at trivago, and would like to share some insights into one of our biggest projects we tackled in the last period. Designing trivago's new mobile app!

TL;DR: a weekend project for transferring data via animated QR codes, written in Go and using fountain erasure codes. The Go code is reused for mobile apps using Gomobile, and in a web application for automating testing QR codes parameters, built with GopherJS and Vecty framework. I’ll share my experience building it, some code and benchmark results of using animated QR as a data transfer method.

Cicada 3301 is an organization who used puzzles to possibly recruit codebreakers/linguists from the public. The first internet puzzle started on January 4, 2012, and ran for approximately one month. A second round began one year later on January 4, 2013, and a third round following the confirmation of a fresh clue posted on Twitter on January 4, 2014.

MongoDB Schema Design – Many small documents or fewer large documents? Source : Stackoverflow Modeling One-to-Few An example of “one-to-few” might be the addresses for a person. This is a good use case for embedding – you’d put the addresses in an array inside of your Person object. One-to-Many An example of “one-to-many” might be parts for a product in a replacement parts ordering system. Each product may have up to several hundred replac..

I seem to be more efficient in getting through rss feeds by individually browsing through related content. That is, I can get through all Emacs entries a lot faster if I look at Emacs content exclusively, instead of mixing with say BBC news. Elfeed filters are great for filtering related content. I wanted a way to easily switch through my typical categories of related content by quickly changing elfeed filters using a completion framewo....

What’s a PiHole ? < It’s basically a DNS sinkhole. DNS servers resolve domain names into IPs. DNS sinkholes are basically faulty DNS servers. For example when you go to a website your web browser will also download ads. In order to get them it has to resolve the domain name of the ads provider into an IP. That’s what DNS server does. PiHole is just a local DNS server which say ’nah’ when you ask it to serve a content from a blacklist..

What does it take to be awarded the ShipIt Day Golden Keyboard? ShipIt Day XIII concluded last week after an intense 24-hours of brainstorming, building, and presenting. Various projects were completed by Cerner associates across twelve diverse organizations. ShipIt Day XIII’s projects were some of the most technically advanced this competition has ever seen. Awarding the Golden Keyboard is no easy job for our judges. Back in 2014, the tro..

Credit cards give you cash back or airline miles. Ebates gives you cash back (or a “Big Fat Check” as they call it). But a new app called Bumped gives a fresh idea to the loyalty game: stock in the very companies you shop at.

In the previous post we explained from a theoretical point of view how a block chain works. In this post we will get down to work and will implement a working blockchain in Go. If you haven’t read it yet , we recommend you to do it now before continuing. It’ll provide you the basic concepts needed to understand the examples below. (You can find the complete example in this Github repository: https://github.com/dplabs/demistifying-bl....

I used neural networks to recognize and remove human bodies from videos, simultaneously trying to fill the void they left. Why? Well, as we are externalizing not just our bodily actions to tools, but our decision process to all-knowing, all-loving AIs, the traditional, perceivable image of what constitutes a human body has become obsolete. It seems oddly fitting in that case, for disembodied neural networks to remove our outdated bodily ima..

Following up from faster junk mail deletion with mu4e , elfeed is another candidate for enabling actions on pages. In this case, marking rss entries as read, page by Page. If on use-package , the function can defined and bound to the "v" key using: (use-package elfeed :ensure t :bind (:map elfeed-search-mode-map ("v" . ar/elfeed-mark-visible-as-read)) :config (defun ar/elfeed-mark-visible-as-read () (interactive) (require 'windo..

How the Wrong Architecture Can Cripple Development A couple of years ago, I was working on a side project with a few friends. We thought that it would be the next big thing. We put our collective best efforts into it; I worked long, hard hours fleshing out the scaffolding of the perfect architecture. Little did I know that my effort would doom the project to join the abyss of failed projects as quickly as it had begun. We had the best ....

Introduction Concurrent programming allows developers to solve problems using more than one path of execution and is often used in an attempt to improve performance. Concurrency doesn’t mean these multiple paths are executing in parallel; it means these paths are executing out-of-order instead of sequentially. Historically, this type of programming is facilitated using libraries that are either provided by a standard library or from 3rd pa..

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.
