To debug org related bug, org-reload reloads all lisp files in ~/.emacs.d/.local/straight/repos/org/. Reloading config.el files should inform you what information has been overwritten. If you use Doom Emacs and modify either package.el or init.el, you must run doom sync in your terminal (outside of emacs), then consequently run doom/reload inside Doom Emacs for modification to correctly take effect. It is important to note that you should always make sure to set custom-variables — variables declared by defcustom — using custom-set-variables.

“Adding jump state to command.” implies that position ((point)) that the added command is evaluated is added to jump state. In the other word, you can get back to (point) that you executed the command by using (better-jumper-jump-forward). I was trying to add “jump state” to (+spell/previous-error) and +spell/next-error. Note that +spell prefix means this command is provided by a Doom’s module. From a quick glance into the code, it is clear that — just like other Doom’s module — it implements branching condition to allow fallback behavior based on context such as current mode or available packages.

Lets inspect combobulate-navigate-previous by step into the function. The following functions are called in order: combobulate-navigate-previous combobulate--move-point-to-node responsible for display and move node. (combobulate--navigate 'previous) pass previuos to combobulate--navigate combobulate--nav-get-prev-sibling get sibling node by query its parents node and get all of its nodes. sibling nodes are arrange in order, so getting previous or next siblings nodes is easy. combobulate--nav-get-sibling-nodes outputs list of nodes seq filter check for matched node.

History of edit Last edit is <2022-11-28 Mon>. There are 3 components to pay attention to including: conda.el, lsp-pyright, and flycheck. First, conda.el allows user to activate conda env from within Emacs. Users can check conda.el by checking conda-env-home-directory, conda-env-current-name, and conda-env-current-path. Second, LSP is language server a general concept outside of Emacs and python. LSP may have type checking as its feature. lsp-pyright is python language server (called “pyright”).

I always get lost in the detail when learning or working on math, and I find that new math concept introduced only a few important concepts. The rest are filling in details by connecting new and old concepts in the right order using math notation. Think of new math concepts as tools that are reusable for tasks in which tools are specialized for. In this series of “Explaining X” where X is any mathematical concept, I will try to avoid mathematical details and will try my best to capture the newly introduced concept.

I was trying to implement my own scratch buffer.I learned alot about Emacs’s way of programming. I gained a new mental debugging tool. The main function I started to modify is doom/open-scratch-buffer. The functions deals with opening scratch buffer when current-buffer is inside and outside of a projectile’s project. doom/open-scratch-buffer does the following check if scratch will open in the same buffer or as pop up buffer Then, it passes arguments to (doom-scratch-buffer &optional DONT-RESTORE-P MODE DIRECTORY PROJECT-NAME).

Doom discord announces important update and fixes. This is where you should take a look first before attempting to pull remote commits that are ahead of your local commits. Doom emacs has only 1 branch. It used to have 2 main branch master and develop branch, but Henrik give up on develop branch because, I assume, its too much work to make develop branch stable before merging to master. For this reason, instead of merging develop branch to master branch.

I couldn’t use setq and custom-set-variables to have org-refile shows list of newly set org-agenda-files. Started to solve, first suspect I found was when I learned about custom.el file. Custom variable set by defcustom will set custom value in custom.el. I reset all custom.el to nil to make sure that it doesn’t set custom variables under weird condition that I am not aware of. I reloaded Doom Emacs. Changed variables didn’t reflect in helpful-variable, and org-agenda-files was not set to nil — value shown in custom.

Note taking is a skill that everyone seems to think that they have “solved” it. Whatever that means. They are not interested in investing their time to improve their note taking skill. No interest. No skill. No framework. Regardless of my critique, I think they draw conclusion fairly. Why? around 6 out of 10 people are knowledge worker 1. A subset of those need to use note at all. A subset of those who use notes need to create reusable notes.

Last edited [2022-06-23 Thu] Note: This blog will mostly likely ever changes as I form my preference of what I think a good blog should be. Blog. Piece. Article. Whatever you called it doesn’t matter. I will redefine it here. For the rest of the blog, I will use the word blog. I define blog as followed Blog is a collection of text with a goal’s guided narrative.

“Internetworking Architecture” (Leiner et al. 2009) was a fundamental design that enable machines and computers to communicate via internet regardless of underlying communication protocol. TCP/IP were implemented in UNIX operating system triggers a widespread adoption of internet (Leiner et al. 2009). Dispersion of protocols began in research community. Recall that predecessor of internet project (it was named “internetworking” at the time) was funded with the goal to increase speed and efficiency of research collaborations.

An EC2 instance has 4 state of life cycle: running, stopped, and terminated. Furthermore, state transition (or action) of an EC2 instance is launch, rebooting, pending, shutting-down, and stopping, see <ec2_life_cycle>. Figure 1: EC2 instance life cycle Validating that you have correct setup This article assumes that you have setup AWS credentials in your terminal environment. You can check out one of my article named “Setup AWS credentials for your AWS account and create new user” to help you set things up.

In AWS IAM, a policy is the smallest entity of permission. There are types of policies: resources-based policy, identity-based policy, and session-based policy. Figure 1: aws policies Policies can be attached to the following “identity”: user (1 account can have more than 1 users), role, and group (a group has many user) 1. user, role, and group are called identity. In AWS identity is called IAM identity and user, role, and group are called IAM user, IAM role, and IAM user group, respectively.

Straight’s recipe is similar but not identify to one used by MELPA. 1 A recipe describes which local repository to link the files from and how to clone that repository, if repo is not found locally. With this definition of recipe, one can think of recipe as a build step (recipe) of a package. Ultimately, a package is defined is a collection of files required for package’s build. striaght.el views a package in this manner.

This article is based on staright.el README which at the moment doesn’t have written document on how transaction works. So This is a work in progress until I either read straight.el codebase or summarize its documentation. Conceptually, stright.el clones Git repo and them symlinking files into Emacs’s load path. A packages in straight.el is defined as recipe as a files which was symlinked together. I have an article on recipe.

Ask youself the following question. How do you know your understand something? How can you access much do you understand it? If you don’t fully understand it yet, is there a way you can make a snapshot of things that you don’t understand such that you can replace this snapshot whenever a better “version” available to you. Why ability to assess your level of understanding it important? you asked.

When I first get into Emacs, I was a vim user before, so I picked up Doom Emacs without experience with vanilla Emacs. Transition has been smooth so far, but because I never has experience with Vanilla Emacs before when I encounter a bug in Doom Emacs. I always have to first figure out if it is Doom Emacs problem or Emacs problems. Because of this, I put out a new blog series to help me build a stronger foundation of Vanilla Emacs.

This article is an opinion piece on Comparison to other package managers. Emacs package manager are split into 2 categories: package.el wrapper or not package.el wrapper. One idea that straight.el emphasizes a lot is that straight.el manages commits rather than managing a whole a package. Some PM only accept latest commit. Other only accepts repo on github etc. I call this design decision a “smallest unit of design implementation.” Other unique takes on managing Emacs packages are Borg (assimilates packages as Git submodules into .

Personally, I think snippets is under untilize. Same as notes. The fact is people just don’t do neither snippets or notes. I defined code snippet as followed A collection of either small/large code which may store in single/multiple files that you will revisit against in the future. Focusing on manging code snippets in emacs, few packages come to mind including: yassnipet, auto-yasnippet, yankpad, and code library. In my workflow, to share code snippet with others, gists is needed.

Dev logs is new blog series which dive deep into implementation level. The goal is to understand how things works. I figure this should be an interesting series because I always wanted to know how these program works underneath. Instead of explaining the whole code base, I will only focus on the “magical” part that sparked my interest the most. Todays I present to you aya. I started of the series with aya because, I think, it is a small package with the right portion of magic.

This is my summary of a more thoroughly explained evil guide, see here. Keymap Precendence in vanilla emacs overriding-terminal-local-map for terminal-specific key bind overriding-local-map keymap char property at point keymaps for the current character. Yasnippet keymaps are in this category. emulation-mode-map-alists. Apparently, its more multi-mode keymap management. I am not sure what this means, but if i have to guess it is used in modes that have its known key precedence or other complexity that its key binding system brings.

By now, in <2022-12-08 Thu>, it should be conclusive that any type of contents are best organized/managed using database. Responsibilities of database includes retrieve/store data. That’s it. However, emacs manages data as text. Advantages of this is simplicity, but, this argument doesn’t even work anymore. why? Emacs supports SQLite as built-in! I like Emacs because of level of compatibility that it provides, but it frustrates me to realized that open source community is not as collaborative, as a result, Emacs slow to adopts.

Resources are provided in my roam research note. I successfully connect x-apps via x11 protocol by first installing and launching xming server. Xming application provides x11-server. Then, I need to tell the wsl2 “address and port of X11 server to connect wsl2 application to” (my note on x11 can be seen here) X11 server is enlisted as WSL2 entrusted DNS which located in resolve.conf.

Hello, guys This essay is my interpretation of a discussion on “NFTing the World for the General Good” episode on Real Vision TV. The information in the essay are adapted to fit rational narrative that I have in my brain. This is the beginning of the essay. The four phases are categorized into the following transaction an physical assets transaction of electron transaction of information transaction of digital assets Each phase increase efficiency of transactions which depends on three factors: object, process, and rules.

According to dictionary, freedom is defined as The power or right to act, speak, or think as one wants without hindrance or restraint. Power is defined as The capacity or ability to direct or influence the behavior of others or the course of events. That’s is power is defined by abilities to restrict others’ freedom. Therefore, by definitions, an individual with more power has more freedom than others.

This stack exchange post state the following. Debian and RPM packages don't contain source code, only the compiled result. However, you can fetch the source packages - SRPMS, or the Debian description, patch, and original tarball. That’s it. You can only download file that are provided in url where target deb file is located. Which files will be provided? Only package maintainers can determine that. Therefore, there could be a scenario where no source codes are available for download.

This is a summary on Chapter 21.1 Two-Phase Locking Techniques for Concurrency Control from Fundamental of Database system by Pearson 2015.

You can rebuild the site in many different ways, but the most common way is to run `jekyll serve`, which launches a web server and auto-regenerates your site when a file is updated. Jekyll requires blog post files to be named according to the following format: `YEAR-MONTH-DAY-title.MARKUP` Where `YEAR` is a four-digit number, `MONTH` and `DAY` are both two-digit numbers, and `MARKUP` is the file extension representing the format used in the file.

All of the content I presented below can be found at Auto-YASnippet Github repo. Auto-Yasnippet (aka aya) provides the following interactive commands: aya-create, aya-expand, aya-persiste-snippet, and aya-open-line: I don’t quite understand aya-open-line yet, so I will not be explaining it here. This snippet package support ad-hoc style of editing workflow where you can create useful snippet to be reused as you editing. Without aya, one would have do the following

Alan Kay famously critique World Wide Web (WWW) where HTML is originated. He publicly dislike HTML as followed Things like [HTML] happens when we let physicists play with computer. He stated that HTML is a bad markup language because people who build HTML thinks their way of representing web page is the only way. He mentioned a (older and) better alternative to HTML is to define protocol based on ordered region on a tape — back when tapes were still popular means of storage in 1950’s.

As an example, I will use api.github.com as a API endpoint. If I use ~/.authinfo.gpg as an auth-sources file. (variable name is auth-sources), I need to add the following to the file where I need to sub value into user-username and user-password. machine api.github.com login user-name password user-password auth-source-search is a function that retrieve password from your specify auth-sources file. You can use it as followed. This will output list of property where :secret key has your password as its value.

Edit History last edit on [2022-07-30 Sat] Money is the most flexible medium of exchange. For more detail please refer to my blog named “Money Is A Type of Token.” Motivation drive efforts. Effort is a seed of creation and innovation. It just happens that money provides universal motivation due to its utility which is measured by speed of conversion from itself to other assets. Money has fastest conversion rates.

Doom Emacs has its own keybinding system. A more accurate explaination is Doom Emacs keybinding system is a wrapper over evil mode such that it is smoothly compatible with Emacs. If you use Evil mode without Emacs configuration framework such as Spacemacs or Doom Emacs, it is frustrating to know if your keybinding is setup properly and whether it will always work as expected in any circumstances. A common point of failure is when your keybinding is overwritten by some packages.

Edit History last edit on [2022-07-30 Sat] I can refine this blog more by consolidating the current content to my notes on roam research. I don’t have time to do this at the time of writing. In theory, there is no need for “medium” of exchange. Any exchange can be anything as long as seller and buyer agree upon. Therefore, one can argue that there will always exist a sequence of exchanges of agreements that satisfy any pair of sellers and buyers.

The normal workflow of lookup documentation would be to search google, stack-overflow, etc. Alternatively, if you are using IDE, IDE will lookup documentation for you, for example goto-definition etc. Very convenience. What else do you need? Although, searching online directly is not the best approach, it is everyone last line of defense. On the other hands, IDE is as good as it gets. However, the problem with IDE is that it is context specific.

there are three categories of note taking process organize files. write notes on a file. search files and notes (aka completion in emacs) organize notes reference to file. First two are easy to achieve. Put notes and pdf files in folders does the job. The third condition is arguably not difficult neither. One can search for a file given a file directory quickly which can be done with any of the completion packages (e.

I propose “Note Taking Pipeline Framework” as my take on how I implement my “second brain.” I would argue with a high degree of certainty that this framework is the best in the world without degree of exaggeration. I think of note taking as a type of data storage with a property that satisfy my note taking philosophy. I wrote about philosophy of note taking in my blog titled “Philosophy and Meta Physics of ‘Notes Taking’".

Modern OOP is misused and misunderstood. Modern OOP create an object to abstract over the object internal state. Originally, OOP is intended to be used to abstract objects over the most important processes that take place within environment in which objects exit. This is done by exposing interfaces that are capable of interacting with the outside world 1. In the other word, an object should be built to be resurgence, to protect itself from dynamic environment.

As an example, the goal is to run container that will download things hosted on the web and run some command DURING a docker launches (using ENTRYPOINT to run the command).

AWS credentials and configuration to your AWS account. AWS configuration file and credential file can be found at ~/.aws/config and ~/.aws/credentials. Once that done, you can use the following to get your account information. aws sts get-caller-identity It will not show secret key aws_access_key_id and aws_secret_access_key which you have set. It will only show information of your account including: UserId, AccountId, Arn. AWS users Note that 1 account has 1 root and can have many IAM user.

Incentive is an underlying mechanism that drive society at any scale including individual, group of individuals, and human population as a whole. Incentive is an abstract concept. Physically, incentives are driven by money, refer to my blog titled “Incentives of Owning Money” for more detail. Another important concept is to accept that money is an indirect form of freedom and power, refer to my blog titled “Blog Freedom and Power are two sides of the same coin” for more detail.

Quoting “D-Bus integration in Emacs” 1, D-Bus is defined as followed D-Bus is an inter-process communication mechanism for applications residing on the same host. The communication is based on messages. Data in the messages is carried in a structured way, it is not just a byte stream. According to 1, name of client application is “a series of identifiers separated by dots”, but an application can install multiple objects under its name which are represents as path like syntax – separated by /.

I was trying to figure out +lookup/definition that open in other window.
