Not that much to report today mostly some tweaks to my rust blockchain miner exercise. I remembered rust has binary literals and bitwise operations are one place they actually are useful. I've watched all the Into Rust tutorials/exercises and they were great but there's only a handful. I did an exercism on isograms and demoed my rustblock program during Thursday evening demos. As tends to be the case, I learned a lot from the RCers while ..

With CSS filter effects and blend modes, we can now leverage various techniques for styling images directly in the browser. However, creating aesthetic theming isn't all that filter effects are good for. You can use filters for web performance, too.

This morning I tweaked my hexagonal lambda tooling and tests. No big deal. I also started watching the "Into Rust" screencasts. The first one is great for answering the "Why Rust?" question which I got asked twice today already. After lunch I paired on the inner guts of a blockchain miner in rust. Just enough to combine a nonce with an array of block payload bytes and hunt for a sha256 "golden nonce" with a given number of leading zero bi....

Wanted to quickly execute an Objective-C snippet. org-babel didn't support it out of the box, but adding it was straightforward (looked at ob-C.el and ob-java.el): (require 'ob) (defcustom org-babel-objc-compile-command "clang -x objective-c -framework Foundation" "For example: \"clang -x objective-c -framework Foundation\"." :group 'org-babel :version "24.3" :type 'string) (defun org-babel-execute:objc (body params) "Compile Objectiv....

When it comes to campaigning for a change, it can be difficult to create the momentum needed to make a difference. Unless we are fortunate enough to be in a position of power or influence, we can struggle to make ourselves heard or to see any real progress towards our goal.

I’ve been meaning to add a commenting system to this blog for a while, but I couldn’t think of a good way to do it. I implemented my own commenting system on my old Django personal site . While I enjoyed working on it at the time, it was a lot of work, especially to fight the spam. Now that my blog is hosted statically on Github’s servers, I have no way to host something dynamic like comments. Disqus seems to be the popular solution t....

One of the most challenging aspects of investing is lack of foreknowledge or future knowledge - we simply do not know what the performance of a stock or index fund will be. But what if we could print out a list of opening values of a stock and then take a time machine backward in time and invest with foreknowledge? Would we be able to make much more money than otherwise possible?

This morning I wrote a script to manage AWS session tokens and asked for a code review. Not optimistic that I'll ultimately use it and I'll probably go back to aws-vault, but at least it works now and I can test drive it. I did the 3 next exercism rust exercises. There are 70+ of them and I'm worried they are too much about basic programming problems and not enough about how to write idiomatic rust, so I think starting tomorrow I'm going ..

C++ smart pointers are pointers that wrap raw C++ pointers. There are several types of smart pointers in C++. This article will be about the weak pointer (std::weak_ptr) in the C++ standard that is a type of a smart pointer. It’s closely related to the shared pointer (std::shared_ptr) that is also a type of C++ smart pointers. Other types are unique_ptr and scoped_ptr . There was also an auto_ptr, but it was removed in C++17.

This morning I integrated the rust clap crate into some of my little CLI exercise utilities and learned a bit about dealing with a mix of Option and Result types, which is annoying. clap is really nice. I found a problem with the docs and filed a github issue and sent them a PR. It's actually ultimately an issue with the crates.io website code so I'm hoping one of those maintainers makes a fix that will handle the situation for all crates. ..
