Snapshot of the (technical) problems I’m thinking about right now: AWS: Logging is a special case of telemetry (or vice-versa). Unify telemetry logging client. Incremental step: logging system is a “sink” for the telemetry, and the source of truth for querying metrics logs. Reimplement the metrics “collector” to be browser-compatible. Currently it uses nodejs async_hooks. Need to get this done before another 6+ months of technical debt accrues. 1 week of work. Redevelop the API for ...| Posts on sink

Software projects produce artifacts—a concept less particular than package which has a version, manifest and structure conforming to some package system. Package systems are smart, and thus complex. The key feature of an artifact is that it is dumb. Package management is a hard problem, with lots of half-broken systems serving particular ecosystems: Cargo for Rust, pip for Python, NPM for node.js, Maven for Java. Artifact systems are not so well-studied, though the concept is high-leverage:...| Posts on sink
Quietly tucked away in the last slide of a 2011 Netflix cloud talk (Mr. Cockcroft talks a lot): Cloud Standardization? Cloud features and APIs should be a commodity not a differentiator Differentiate on scale and quality of service Competition also drives cost down This is a claim that competition and standardization are desirable and beneficial at the individual level—an insight perhaps also employed by Google with its Chrome and Android strategy. ESR made the case that there is economic m...| Posts on sink
technically superior plugin isn’t always the most popular. hard to gain traction with users. signify is better than gitgtutter, but it didn’t hit the front page of HN sneak is better than seek, but seek hit the front page of HN plugins with better marketing/branding don’t always win. sneak has better branding. (but signify doesn’t really do much to market itself) you can announce the same thing every month and it will be completely new or at least newly-compelling to many people. each...| Posts on sink
The generalization of this is “communication”, but trying to focus on “improving communication” leaves important stones unturned. Like “end poverty”, it is a mission that begins without a fully-formed thought. There is no supply of communication that can be buttressed; rather, to improve communication, instances of the abstract must be identified. Shannon crystallized this as the problem of encoding information. We know from practice of information theory that information encoding...| Posts on sink
disadvantages: I became familiar with Vim very gradually. By the time I found out about pico, I had long been editing X86Config with i and :wq. I was thankful for the syntax highlighting and remote availability writing C and Java on a Solaris ssh account. I embraced visual-block-mode during late nights at the CMOS lab after editing hspice input vectors manually became intolerable. I internalized [hjkl] by using Gmail shortcuts. And on OS X, actively-developed open source editors are few.| Posts on sink
I wrote a toy parser (or rather a parser specification in the syntax of a parser-generator) for COOL, and I’m wondering if mature, popular languages actually use these things to generate their parsers. The PMD project makes use of a (modified) copy of the JavaCC parser-generator definition for the Java grammar. Inspection of that file reveals the initial 1997 timestamp by author Sriram Sankar. According to Advances in Software Engineering, “The Java 1.1 grammar was developed by Sriram San...| Posts on sink
I stashed this away long ago and can’t find the source (HN? reddit? a blog?). Funny how lossy the web can be… Brendan Eich: Performance gaps in JS engines get filled all the time. This is different in kind from potentially adding a second VM, requiring cross-VM-heap cycle GC, etc. See https://lists.webkit.org/pipermail/webkit-dev/2011-December/018811.html Dennis described some of C’s flaws (which JS inherited) in typically humble style here: http://cm.bell-labs.com/cm/cs/who/dmr/chist.h...| Posts on sink
Frances Allen: C has destroyed our ability to advance the state of the art in automatic optimization, automatic parallelization, automatic mapping of a high-level language to the machine. Example from HN user ‘waps’: one example [vs Haskell] that C can never hope to optimize : deforestation. Before optimization : the programmer requests a list to be created, fill it by calling functions and then passes the completed datastructure list (or tree) along to another function, which executes co...| Posts on sink

We’ve all been there, perhaps some never leave: Having wandered the halls of a haunted debugging session for most of a day, you happen upon a room containing a piñata. In delirium and desperation, you ctrl-v and f5 the piñata until a cookie falls out. Somehow, your mad key-strokes have busted the ghost bug; time to go home, yay! Sometimes software code doesn’t fit perfectly. Third-party integration, protocol bugs, opaque libraries, timing and async bugs, and Katamari technical debt prec...| Posts on sink

Levels of aspiration: Arguments like “but it works” or “it gets the job done” are tell-tale signs of someone happy at the lowest level of the technical hierarchy and your cue to just quietly back out of the debate. —DHH I bet you over-engineered your startup: Of the three startups I've worked with, two of the three were ridiculously over-engineered monstrosities that were way over time budget.

Notes from Dr. Stephen E. Saddow's presentation, "Silicon Carbide Biomedical Technology for Bone Implants, Stents and Brain-Machine Interfaces". Electrical Engineering Department Department of Molecular Pharmacology and Physiology University of South Florida Abstract: Amorphous silicon carbide (SiC) has been used for several years as a non-biofouling coating in biomedical devices such as coronary stents and bone implants. However, up to recently, the biocompatibility of single crystal SiC,...| Posts on sink

It is a question that you will face, should you deign to start a blog (or column, journal, etc.). EUTHYPHRO: Why do you have a blog? YOU: Because it exercises my urchin mind and I want to share my meager kibbles with SearchEngineGod. Weak answer. Too cliché.

I am reading about and attempting to discuss the holographic principle, a conjecture in theoretical physics that the three-dimensional universe is a projection of a two-dimensional (i.e., surface area) encoding¹. This would imply that all the particles and properties and everything of our universe may be compressedsubstantially without losing information: reality is a (logical, not literal) projection of a very large bitmap. The theory also could “explain” surprising properties of the un...| Posts on sink
Learning without thought is labor lost; thought without learning is perilous.- Confucius It is said that some people are “quick learners”. Does that mean they can learn anything quickly? No step in the path of learning challenges them? No; rather, they learn quickly compared to others, but that quickness is nevertheless measured in mortal units. For slow and quick learners alike, the process of learning requires some time and concentration. Over time, you can master your shortcomings and ...| Posts on sink
It even shows inodes usage. A 100 MHz P1 was overkill. I've bid vale to my beige-box IPCop firewall. I had built it in 2004 out of a circa-1996 Pentium machine and a couple NICs. For 6 years I've wondered when this little choo-choo would die... it never did. Some neat things about IPCop compared to its contemporaries: usage graphs, port forwarding, intrusion detection, dynamic DNS; plus other things I never used, such as traffic shaping.| Posts on sink
Using Cygwin on Windows, sometimes you need to run a bash command or script from the Windows command line (CMD, DOS, shell). This is particularly useful if you want to use the Task Scheduler instead of messing with cron on cygwin. If you’re going to schedule tasks on a Windows system, then the Windows Task Scheduler is probably the sane way to do it. To run a bash script or command from outside of cygwin, you need to pass it to the bash executable with a little prep work. That “prep work...| Posts on sink

Tartt, Donna. The Secret History. New York: Knopf Books for Young Readers, 2004. The original copyright year is 1992, so that explains why everyone uses payphones, and most knowledge–or rather, information–still, is available only at a premium, that is, by the study of untranslated primary texts, or contact with the educated. The book is dedicated to Bret Easton Ellis; it turns out that Ellis mentions the characters in one of his own novels. I wonder if the market for cocaine-rusted LA ki...| Posts on sink
