Time On The Internet - venam.net - 7 years ago - eng
Time can be measured in all sorts of ways, some more accurate than others, but the perception of its flow varies widely depending on the subjective experience. That's the distinction between physical and psychological time. Psychological time is influenced and influences our cognitive systems. It influences how we act and respond to information and events around us, and the information and events around us influence it.

Back in December of 2004 I started a new life from zero. I was 22 years old without any money, education or connections. I borrowed my mothers computer and started to learn HTML and internet marketing. Each year I publish an annual report. Earlier reports are linked from the history section in my about page. Personal [...]

Testing emails The way I used to do it is to have all emails sent to me via a configuration setting in either Symfony or Laravel. This works fine but there can be a significant delay between the moment when the email is sent and the moment it is received, which is annoying. I have heard about mailtrap, which is a hosted service that does more or less what Mailocal does. But I’m not a fan of sending my customers’ info to a third party. M....

I’ve had a bit of a crazy week. Tuesday, I got a tour of the Pentagon from a friend that is in the US Digital Service (USDS) for the Department of Defense (DoD), called the Defense Digital Service (DDS). Wednesday (the day of writing this), I shadowed a friend who is a surgical resident during their shift in a hospital. Friday, I have plans to shadow a friend who is an investment banker at a private equity firm and will do a follow up po....

Jane Street is sponsoring this year’s MakeMIT hackathon , and we wanted to create a prize for the winners that would do justice to the maker spirit of the competition. As makers ourselves – it’s not unusual to find a “software” engineer here who hacks on FPGAs or who has a CNC machine at home – it felt natural to get our hands dirty.

At Jane Street, over the last few years, we’ve been increasingly exploring machine learning to improve our models. Many of us are fascinated by the rapid improvement we see in a wide variety of applications due to developments in deep learning and reinforcement learning, both for its exciting potential for our own problems, and also on a personal level of pure interest and curiosity outside of work.

I open sourced my first HTML5 game as a resource for other developers working with Phaser.js or wanting to build their own game

The snapcraft CLI has supported building ROS1 snaps for a while via the catkin plugin. We supported the ROS2 betas via the ament plugin, but that was before Open Robotics had a ROS 2 package repository setup, which meant that the ament plugin built the ROS 2 underlay from source, and it was predictably dreadfully slow. However, the stable releases of ROS2 introduced a new build system called colcon, and also had their own package repositori..


If you mine cryptocurrency such as bitcoin, you’re making money. If you’re also in the US (or are a US citizen abroad), Uncle Sam wants his cut.

This one is just for future reference for me that I may find useful one day - a website full of resources that may be useful for naming things.

Over the years, people involved in computer science and engineering have worked really hard on optimisations of various natures.

I gave a presentation at the Utah Elixir Meetup this February. Here’s the recording of my presentation: Watch on YouTube I’ve posted the slides as an HTML file, along with some materials to follow along with, on my GitHub account . Check it out!

we found that 44% of docker image scans had known vulnerabilities, and for which there were newer and more secure base image available. Most vulnerabilities originate in the base image you selected. For that reason, remediation should focus on base image fixes.

A good number of security vulnerabilities are discovered and fixed in non-official channels. We measured Snyk DB to uncover 67% more vulnerabilities than public databases. In 2018, new disclosures for npm grew by 47%, and Maven Central grew by 27%

Maintainers stated their security knowledge is improving but not high enough, averaging 6.6/10, and 1 in 4 open source maintainers do not audit their code bases.

Only one in three developers can address a high or critical-severity vulnerability in a day or less. The more we use open source software, the more risk we accumulate as we’re including someone else’s code that could potentially contain vulnerabilities now or in the future.

A worrying 27% of respondents stated they do not have any proactive or automatic way to find out about newly discovered vulnerabilities in their applications. 37% of users of users don’t implement any sort of security testing during CI.

Regex for for a single-threaded runtime could be devastating. We’ve also detected that the npm ecosystem has seen the most XSS vulnerabilities, Maven Central and PyPI follow next.

We had a meeting recently with 16 people on the video conference call. Due to poor planning and technical issues it took nearly half an hour to decide to postpone the meeting. That is eight man hours wasted - a whole day of work!

tldr; I'm working on a AOT-compiled Javascript implementation called jsc . Many dynamically typed programming languages have implementations that compile to native binaries: Python: Cython Common Lisp: SBCL Scheme: Chicken Scheme The benefits of compiling dynamically typed languages are similar to those of compiling statically typed languages: Simplified deployment via a single binary Simplified foreign-function interfaces e.....

After making a few changes to this blog in an attempt to appease Amazon and failing , I wanted to undo those changes. Thankfully, since this blog is hosted on GitHub pages, it’s versioned controlled via Git. Meaning I should easily be able to find the changes and undo them fairly easily.

The advantage of OpenID Connect is the fact that it’s standardized and widely adopted. This means that a library or tool designed to work with, e.g. Google accounts, can easily be adopted to work with e.g. Microsoft’s Active Directory or the Norwegian national ID provider ID-porten. Different Identity providers can support different levels of trust between you and your users. In my next few blogposts, I will explore different OpenID Connect..

Welcome to the first edition of a new exploit series we’re calling “Snyking In”! We’ll be looking at various security vulnerabilities, demonstrating how they can be exploited, as well as the potential risk they pose to your data and systems.

You can find my goodreads account at goodreads.com/jessfraz . Romanticized Tech I call this genre of books “romanticized tech” because of the way tech is portrayed in them in a very idealistic and whimsical way. It’s nice to pick up one of these if you are feeling very “Black Mirror” to remember why you might have even started in this field. Soul of a New Machine : Bryan Cantrill recommended this to me and it’s amazing. It’s about D....

We’re proud to announce our 1.10.0 release of HypriotOS - the fastest way to get Docker up and running on any Raspberry Pi. Features of HypriotOS Latest Docker Engine 18.06.3-ce You can use the latest features of the freshly-baked Docker Engine 18.06.3-ce that is still warm. It includes the Swarm Mode, which allows high availability of services in a multi-node cluster within just a few simple commands. This version contains a fi....

I open-sourced this fun little program: https://github.com/glaretechnologies/fractal It animates a Julia set in realtime using OpenGL shaders. It has some funky colouring techniques so looks a bit nicer than your average fractal.
