Cisco RV130 Router Manual (PDF) Issues I set up a network - a router, two access points, a few switches and ~ 15 to 20 devices. Issues that need to be resolved: I want to be able to access the network from the outside. I want to give priority to VOIP devices. Privacy errors when trying to access Google sites (google.com, youtube.com, gmail.com). Access Network from the outside ¶ Now the network looks like this:

I knew embarrassingly little about The Box™ when I bought it. I spent weeks obsessing over what kind of vehicle I wanted, but I purchased my current home of two years after only an hour or so of looking it over. For example: I had the truck for nearly a month before I figured out it used to be a moving truck. More specifically, it used to be a Budget truck, and I just had no idea. I only found out by chance observation; if you look clo..

By Michael Natkovich, Akshai Sarma, Nathan Speidel, Marcus Svedman, and Cat Utah Big Data is no longer just Apache server logs. Nowadays, the data may be user engagement data, performance metrics, IoT (Internet of Things) data, or something else completely atypical. Regardless of the size of the data, or the type of querying patterns on it (exploratory, ad-hoc, periodic, long-term, etc.), everyone wants queries to be as fast as possible an....

Recently, I’ve become interested in the so-called “funnel method” of character creation in the RPG Dungeon Crawl Classics. The funnel is a process of deriving your 1st-level character by running a handful of 0-level commoners through a dungeon and seeing who comes out the other side alive. A group of players would need to funnel […]

Chapter 7 of “The Linux Programming Interface” is about memory allocation. One of the exercises, marked as advanced, asks the reader to implement malloc . I’ve decided to give it a shot. My full implementation is available on Github . I will try to break down some of my reasoning on the next sections and include some snippets from the code. Memory layout of a Process The memory allocated to each process is composed of multiple segments,..

A quick post. I was looking at the prices to install a home battery system the other day. During the sales process I was informed that for a modular system such as the one provided by Ampetus that if you don’t buy 2 or more batteries that “you may de rate system capacity” Sound’s impressively scary! Slightly worried I asked that it means. Thankfully what it actually means is that instead of getting 3kW delivery using two batteries t..

I’ve been meaning to talk more about my “Sublime Text and BBEdit” workflow, and this is a powerful (if mundane) example. I don’t write a ton of scripts on my Mac and generally don’t spend much time in Terminal. But when I need a script, I really need a script . My work is very file-heavy. I juggle large numbers of .tex (LaTeX) files across several large folder structures. Every so often I need to copy a subset of files within one folde....

Following my read of “The Linux Programming Interface”, I came across the concept of “file with holes” or “sparse files”. Those are files that try to use the file system more effectively by preventing it from using disk space when sections of the file are empty. The disk storage is only actually used when needed. Sparse files are really useful for backup utilities, disk images, database snapshots etc. One way to create a sparse file is by..

This post is a sequel to Formulating the Support Vector Machine Optimization Problem. The Karush-Kuhn-Tucker theorem Generic optimization problems are hard to solve efficiently. However, optimization problems whose objective and constraints have special structure often succumb to analytic simplifications. For example, if you want to optimize a linear function subject to linear equality constraints, one can compute the Lagrangian of the syst..

Would you say that you think in emoji? No. You think in words, in English. At least consciously that is. Whenever you’re conscious, words show up in your brain and travel the neural pathways to the hands. The fingers are typing on the keyboard and a characters are appearing on the screen. The characters on the screen are each one of the small set we call alphabet. Every thought we want to convey in writing, we have to pipe through this al....

Working at client’s space today, setting up their internal network from the ground up. Learned a few things today: Ideally have: Wall –> Router –> Managed Switch –> Unmanaged Switches (subnets) –> End Users Difference between unmanaged and managed switches: Managed: - can control individual ports - set static/dynamic ips - sniff traffic Also learned about a new (for me) community: https://0x00sec.org/ Similar to HN but mor..

I’ve recently been studying time series analysis and was curious as to whether a time series is correlated with its future self (or past self, as the case may be). This thought came about when studying stock market prediction: the best predictor for the stock market would be a crystal ball that told you the future values.

Back when I was an undergraduate, as part of a class called “Computer Systems Engineering”, we read numerous classic papers of systems design. I enjoyed and learned a great deal from many of these papers, but one that paper that has stuck with me in particular was Saltzer et al’s “End-to-End Arguments in Systems Design”. The paper is a very general tract on systems design – it does explore several examples of concrete systems or application..
