Today I had to look into the a customer whose RavenDB instance was burning through a lot of I/O. The process is somewhat ingrained in me by this point, but I thought that it would make for a good blog post so I’ll recall that next time. Here is what this looks like from the point of view of the disk: We are seeing a lot of reads in terms of MB/sec and a lot of write operations (but far less in terms of bandwidth). That is the exte....

A number of changes have landed in the last week: Implemented let , defn and sugar for quote ; Figured out basic REPL integration with Emacs; Added numeric comparison operators ; Reviewed my Minimum Viable Repo checklist for this project; Fixed four bugs . I also implemented the bulk of the automated tests in the lang....

Tell HN: I have the perfect job, why is it not enough? Link Interesting answers about feeling unfulfilled. Avoiding Micromanagement This is the whole thread with context and what.

Every ruby enumerator supports count. It’s a method that will iterate over every item and return their total count. irb> enum = Enumerator.new { |yielder| ( 1 .. 100 ).each do |i| puts "counting item: #{i} " yielder << i end } irb> enum.count counting item: 1 counting item: 2 … counting item: 100 => 100 However, Enumerable also has size. Except, by default it’s just nil. irb> enum.size => nil A little-known ....

I’ve used many textual browsers , but I’m interested in more hardened options. Browsers parse untrusted content from the Internet but no textual browsers employ sandboxing, continuous fuzzing, or other security measures. Check CVEs for Lynx or w3m and you’ll see what I mean. I’m also looking at alternatives to my w3m-sandbox script to show HTML emails. Pandoc with commonmark-raw_html output is an option; Haskell seems like a better cho..

Since I hate sites that make you read a whole story to get the recipes, out of the five different ice creams, here were the two highest ranking ones. I’d recommend reading more about these recipes Silk Ice Cream 1/2 cup granulated sugar 1/4 tsp xantham gum 2 tbsp light corn syrup 1 1/3 cups + 1 tbsp of Silk Heavy Whipping Cream Alternative 1 cup - 1 tbsp of Oat Milk (you can substitute other milks, but do your math to recalculate the fat, s..

This is a great post to illustrate the utility of detailed alt-text when an image is the primary content. I think it’s less relevant for the more common use of images: as illustrative examples or supplements to surrounding text. Take an image embedded in an article. Sighted users are capable of viewing a detailed image and instantly filtering for the information that’s relevant to the surrounding content. It’s harder to do this with a blu..

Rosetta Code is a programming chrestomathy wiki, that is, it is a site with lots of examples of tasks completed in multiple programming languages. The site has been around since 2007 and now has 1,100+ tasks and 100,000+ code submissions over 900+ languages. To help other researchers, I’m publishing an export of the code samples as a sqlite database via DBHub.io and the source code via Gitlab . Chrestomathy? The OED defines chrestomat....

Like college degrees before them, professional certifications seem to be waning in popularity in the cybersecurity industry. Perhaps as a way to mitigate the well-documented workforce shortage, some companies have gradually begun to account for competence and experience, too, rather than onerous credentials alone — and in some cases, base their hiring decisions solely on those criteria. This is a localized phenomenon, though, exclusively li....

A customer was experiencing large memory spikes in some cases, and we were looking into the allocation patterns of some of the queries that were involved. One of the things that popped up was a query that allocated just under 30GB of managed memory during its processing. Let me repeat that, because it bears repeating. That query allocated 30(!) GB(!) during its execution. Now, that doesn’t mean that it was consuming 30 GB, it was just t....

Ruby has an entire ecosystem of third-party open source libraries which it refers to as gems, or sometimes Ruby gems. In this article, I’ll run through the concepts and tooling that make up the Ruby dependencies ecosystem, and answer some of the common questions Ruby developers have.

A friend recently introduced me to the Meshtastic project, an open source "platform" for creating long range, off-grid, mesh networks for short messages based on LoRa . After playing with the hardware and the software for a few days, here are my thoughts on it and notes on how it works.

As usual, PADD as been update to the release v3.8.0 , and I also updated my custom mod of it for the Pimoroni HyperPixel 4" display and other display with more pixel (800x480) than the original PADD script with the latest updated: Remember that this version is tested on DietPI and with Unbound as DNS. You can grab it from Gist: padd.sh v3.8.0

The other day, a member of SANS’s GIAC Advisory Board asked a question about Mean Time to Detection, or MTTD. In the ensuing discussion, another member cautioned against confusing key performance indicators used to assess individual efficiency, to then serve as the basis for penalties and rewards, with measures of program efficiency. Holding individuals accountable for MTTD, for example, made little sense when that detection relied on fac..

One thing this article misses is the fact that webpages are delivered over the Web to Web browsers. The vast majority of browsers are application runtime environments. Serving pages to users’ browsers creates a software distribution platform. Serving pages in cleartext is a way to give permission to users’ ISPs, network administrators, and governments to serve their malware instead, under your name, whether or not your page includes a....
