As mentioned last year , I’m working on a Artificial Intelligence that can do web design. It is called The Grid . Last week I gave a talk at Lift Conference explaining how it all works. If you can’t see the video embed above, it is also available on the Livestream site and YouTube .

On today’s issue of “one hour hacks”, I’ll show you how you can stop your git drive-by’s to git master from breaking your CI tests… Let’s continue! The problem : Sometimes I’ve got a shitty one-line patch that I want to push to git master. I’m usually right, and everything tests out fine, but usually isn’t always, and then I look silly while I frantically try to fix git master on a project that I maintain . Let’s use tools to hide o..

A little over 3 years ago, a few friends and I started a group called pasten to participate in the Chaos Computer Club’s Capture The Flag (CTF) competition. It is a jeopardy style CTF, where the participating teams need to solve security related challenges in various categories such as exploitation, reverse engineering, web, forensic & crypto.

I’ve been pushing large enterprises to adopt agile development practices for years so I was very excited when I began seeing many of them embarking upon ambitious Agile Transformation projects where they attempt to not only change the way they build software, but completely revolutionise the entire IT process from inception, finance, HR, delivery and operations. But they rarely discuss culture. “Culture” in this context is used to broad..

I’ve been writing a lot of golang lately. I’ve hit painful problems in the past. Here are some debugging tips. Hopefully they help you out. I bet you don’t know #2. #0 Use log.Printf : This should go without saying, but I’m ashamed to say it’s what I use the most. We’ve only been C programming for 44+ years, and it’s still what is most useful! #1 Use go run -race : Since many problems are caused by random races, ensuring..

How does it feel, to return to Germany after a few weeks in Africa? There are no people on the streets. There are no loud sounds. It smells of nothing. It is supposed to be a rich country but is defined by absence.

We’ve all encountered it at one point or another: poor customer support. And it seems to get worse on a weekly basis. “Poor” has many flavors: Not understanding what you want (well, this is actually the better case; the worse The post The Problem with Customer Support appeared first on FullStack - Ofer Zelig's Blog .

As some point I had to generate a random MAC address. This is the snippet I used: import random def randomMAC(): mac = [0x00, 0x16, 0x3e, random.randint(0x00, 0x7f), random.randint(0x00, 0xff), random.randint(0x00, 0xff), ] return ':'.join(map(lambda x: "%02x" % x, mac)) print 'MAC => %s' % randomMAC() MAC => 00:16:3e:7e:f7:fa

I'm often asked by other developers about parts of the pixel workflow, and what fires when and why, so I figured it might be worth putting up a little reference for what's involved in shipping pixels to screen.

You can use "M-x apropos-variable " to get documentation for variables matching a pattern. For more flexibility, some elisp can help with getting a list of all variables matching a regexp: (defun ar/variables-matching-pattern (pattern) "Get a list of all variables matching PATTERN." (let ((matched-variables '())) (mapatoms (lambda (symbol) ;; Symbol is variable? (when (and (boundp symbol) (string-match pattern (symbol-name symbol))....

Take a function \(f\) that maps from some bit string of length \(N\) to another bit string also of length \(N\). Suppose that this function is a 'hash function' with some properties we want: 1) Given an output value, it takes on average \(2^{N-1}\) evaluations of different inputs passed to \(f\) before we get the given output value. Note that if we try all \(2^N\) different inputs, we will definitely find the input that gives the outpu....

Es saß auf der Poolwand eine Eidechse, die hatte ihren Schwanz unter Wasser. Sie bewegte sich nicht, nur das Wasser schwappte auf und ab und es schien, als würde sie mit dem Schwanz wedeln. Ich habe das gefilmt, zwanzig Minuten lang, wie die Eidechse ihren Schwanz bewegt, also nicht die Eidechse und nicht den Schwanz, aber es sah ja so aus. Ich habe das gefilmt, und die Speicherkarte in die Hosentasche getan, weil sie voll war, die Speich..

When this post gained much traction in HackerNews and r/golang, I was both suprised and happy. The general interest made me more motivated to do more and write more. And also some good discussions happend on HackerNews thread that was & will be helpful to me. I decided to package myinit in Go, and rename it to gonit Contributions and ideas are welcome through email and in the issues of the GitHub repo.

In my last article, I showed you how to develop a full-stack JavaScript web application using some pretty interesting and futuristic libraries and web specifications. In this follow-up, I'm going to demonstrate how you can write server-side and client-side unit and integration/Selenium tests for that app entirely in JavaScript.

Er det noen som sammenligner omfang og kostnad på IT prosjekter i Norge? Jeg tror man kunne få noen interessante innsikter dersom man gjorde dette riktig. (Jeg må unnskylde at teksten i denne blogposten blir litt vag - jeg ønsker å si så lite som mulig om de aktuelle prosjektene for å unngå å eksponere andre) Akkurat når jeg var involvert i et tilbudsarbeid for et prosjekt, var jeg samtidig involert i den endelige godkjenningen av et annet ..

I previously noted how to undo your last git commit (ie. soft reset) . Using Magit: M-x magit-log-current . Move point to prior revision. M-x magit-reset-soft (defaults to revision at point). Or if you want a single function: (require 'magit) (defun ar/magit-soft-reset-head~1 () "Soft reset current git repo to HEAD~1." (interactive) (magit-reset-soft "HEAD~1"))

At hackerearth we send emails to keep our users updated on upcoming challenges and their activities, for example, when a user successfully solves a problem, receives test-invitation, updates on user comments. Basically whenever it is appropriate. Architecture It takes lot of computational power to send emails in such large quantities synchronously. So we have implemented an asynchronous architecture to send emails. Here is brief overvie....

CSS Filters are awesome, but you can't do individual channel manipulation with them. Enter: feColorMatrix, SVG filter effect method that allows for really in-depth pixel value manipulation for even better image filters.
