Update, 29 Nov 2019 : Added the section Removing JavaScript and edited the Performance section to reflect the new performance. Introduction This blog used to be hosted on a WordPress installation. I did it that way because, while I had basic knowledge of HTML, CSS, PHP, and other website-building technologies, I couldn’t really be bothered to spend much time making my site better. About six months ago, an acquaintance pointed out ..

I have a few things to say here, so let me say them all up front. Your diet doesn’t matter. Your training plan doesn’t matter. The reason you will never reach your goal is because you don’t want to. You don’t work hard enough to achieve it, and nowhere near hard enough for anything like a diet or training plan to make a difference. Those factors come into play at such a high level, one so far from where you are now, that all the time and ef..

Note : If you're not a Rails user, on OSX, then just nope the heck out of reading this post. This is some serious nerdery here. One of the single most frustrating things about the Rails ecosystem is when you can't get a bundle install operation to finish. The bundle install, of course, is the process of getting the software tools, "gems", identified in Gemfile to install. When you can't get bundle install to finish, you are effectively....

Docker is a container technology that allows you to package up a series of different technologies under (generally) a *nix style operating system. As things deployed with Docker are generally deployed under a *nix style operating system, it isn't uncommon to want to open a shell into your Docker environment for debugging purposes. You can easily do this with: docker exec -it CONTAINER_HASH /bin/bash The CONTAINER_HASH is a value l....

Following up from Enhanced Emacs searching with counsel switches , rather than remembering silver searcher and ripgrep switches, we can use counsel's ivy-initial-inputs-alist to set these up as default visible switches. (push '(counsel-ag . "--file-search-regex '' -- ") ivy-initial-inputs-alist) (push '(counsel-rg . "--glob '**' -- ") ivy-initial-inputs-alist) The default switches stay out of the way in typical searches, but can..



As 2019 draws to an end, we are going to be looking back on some great episodes of our podcast The Secure Developer.


I found this incredible rig on Pinterest, of all places. Inspiration for the next version of mine . Permalink.




MapTiler appeared in the Swiss National TV (SRF1 channel) broadcasted in the main Friday news at a prime time.

As mentioned in the getmonero.org blog post , the binaries of Command Line Interface (CLI) of Monero were recently compromised. -Continue to read the article on SerHack.me




Describing how NextRoll is handling processing petabytes of data using AWS Batch. 15 minute read In this blogpost, we are going to review how NextRoll is using AWS Batch for processing data, and how we benefit from this platform. We will start with an overview of the company and explain our needs for data pipelines. Then we’ll talk about how we are utilizing Batch, reviewing the advantages and disadvantages of this technology. Finally,....

Avdi Grimm wrote an interesting post back in June, about using text to create simple diagrams . He highlighted a few different tools, but one stood out: nomnoml . I used UMLet a lot back in college, to create some mediocre user stories, which soured me on UML in general. I gave nomnoml a shot, though, and created this simple network diagram: Permalink.

Building on the new Kubernetes features in Snyk Container, we’ve been experimenting with integrating vulnerability data more closely into the Kubernetes ecosystem.

This blog post takes addresses a common problem for technical workers - you have been offered a full time freelance gig and you don't know whether or not to take it based on its value versus your current compensation. Note : Traditionally I have done a crap ass job at making these kind of assessments. I'm writing this post to hopefully do a better / more "adult" take at this. What is Your Current Job Worth? Your current job's worth ca....

Like a lot of software developers, I can be pretty forgetful at times. If you're in the industry, you know how it goes: You start working on a project and it is February You look up and … it is May and You don't remember all that much of your life between A good friend of mine refers to this as falling down a code hole (Thank you Mister Mott) and it really is a thing. Some people's code holes are a few days long. Other people's code ....



Similar to our report on Docker image security, we wanted to take a look at the state of vulnerabilities in the public Helm Charts repository.

Goroutines are a unusual and powerful programming language feature, so they are a tempting toy to play with, and they get a bit overused. There is some indication that the following Go principle holds true: Strive to provide synchronous APIs, let the caller start goroutines. To put this advice into a more concrete code example: Do this: func (t *type) Run(ctx context.Context) { // Implementation of background task } Instea....

About a month ago there was an urgent security notice from the Nexcloud devs regarding a flaw in Nginx php-fpm and the associated Nextcloud config .

At home, I can send a link from any device to a local web server that saves it for later. Then, when I have time to read, I can see all my saved articles, move them into folders, and refer back to them as needed. At work, though, those links go into a text file. When I get home, I find the text file, open it, copy the list, clear the file, close it, and then send the list to the server. pbcopy makes that process just a little easier. Now, c..


A close friend recently said to me: I'm Copying You Since You're So Effective with respect to how much I tend to get done and I thought I'd elaborate on this a bit since I suspect that why I'm effective isn't always apparent. These aren't really in any order other than the order that I chose to finish them. I suspect they are all pretty important. Ten Reasons Why I Think I'm Effective Get Rid Of Anything That Pisses You Off . ....

Like so many other things this falls into the category of "I'll do it 100 more times before I die and I can never remember it so may as well blog it". A migration adds a column to a table in a database managed by Rails. In this case I had a table which needed to manage multiple types of data all front ended by an amount method that dynamically figures out why field to fetch back the data from. This gave me a column structure like this: ....

I've written in the past about watching your SQL queries stream by in the Rails console and how seeing, well, stupidity / things that look wrong can help guide you to things you need to find. Here's an example I witnessed recently: habit = Habit.find(2) habit.total_this_month Metric Load (2.5ms) SELECT metrics.date_created_at, metrics.int_val, metrics.float_val, metrics.metric_type_id FROM metrics WHERE metrics.habit_id = 2 AND (date_cr....

Introduction Link to heading I found a manuscript earlier this year (2019), written by my dad about his time in Antarctica between 1958 and 1965. Although he passed away in 1996, I thought it would be nice to publish it, primarily for the benefit of surviving family members. It had been typewritten rather than written longhand, so I didn’t think it would be too difficult.
