+;; bild - a simple build tool
+;;
+;;; Notice:
+;;
+;; This is under active development. For now this is just a convenience wrapper
+;; around `nix build`. The below commentary describes how this tool *should*
+;; work.
+;;
+;;; Commentary:
+;;
+;; Design constraints
+;;
+;; - only input is a namespace, no subcommands, no packages
+;; - no need to write specific build rules
+;;   - one rule for hs, one for rs, one for scm, and so on
+;; - no need to distinguish between exe and lib, just have a single output
+;; - never concerned with deployment/packaging - leave that to another tool (scp? tar?))
+;;
+;; Features
+;;
+;; - namespace maps to filesystem
+;;   - no need for `bild -l` for listing available targets. Use `ls` or `tree`
+;;   - you build namespaces, not files/modules/packages/etc
+;; - namespace maps to language modules
+;;   - build settings can be set in the file comments
+;; - pwd is always considered the the source directory, no `src` vs `doc` etc.
+;; - build methods automaticatly detected with file extensions
+;; - flags modify the way to interact with the build
+;;   - -s = jump into a shell and/or repl
+;;   - -p = turn on profiling
+;;   - -t = limit build by type
+;;   - -e = exclude some regex in the ns tree
+;;   - -o = optimize level
+;;
+;; Example Commands
+;;
+;;     bild [-rpt] <target..>
+;;
+;; The general scheme is to build the things described by the targets. A target
+;; is a namespace. You can list as many as you want, but you must list at least
+;; one. It could just be `.` for the current directory. Build outputs will go
+;; into the _bild directory in the root of the project.
+;;
+;;     bild biz.web
+;;
+;; Or `bild biz/web`. This shows building a file at ./biz/web.hs, this will
+;; translate to something like `ghc --make Biz.Web`.
+;;
+;;     bild -r <target>
+;;
+;; Starts a repl/shell for target.
+;;   - if target.hs, load ghci
+;;   - if target.scm, load scheme repl
+;;   - if target.clj, load a clojure repl
+;;   - if target.nix, load nix-shell
+;;   - and so on.
+;;
+;;     bild -p <target>
+;;
+;; build target with profiling (if available)
+;;
+;;     bild -t nix target
+;;
+;; only build target.nix, not target.hs and so on (in the case of multiple
+;; targets with the same name but different extension).
+;;
+;; Here is an example integration with GHC. Given the following command-line
+;; invocation to compile the namespace 'com.simatime.bild' which depends on
+;; 'com.simatime.lib':
+;;
+;;     ghc com/simatime/bild.hs -i com/simatime/lib.hs -o _bild/bild -v \
+;;         -main-is Com.Simatime.Bild.main
+;;
+;; The general template of which is:
+;;
+;;     ghc <source> -i <deps..> -o <target> -main-is <target>.main
+;;
+;; Some definitions:
+;;
+;; - <source> is some source file
+;; - <deps..> is the stack of dependencies
+;; - <target> is the target namespace, indicated by 'bild <target>'
+;;
+;; To fill out the build template, we can parse the file for known
+;; namespaces. The general recipe is:
+;;
+;; 1. Create a list of namespaces in my git repo. This can be cached, or I can
+;;    integrate with git somehow.
+;; 2. Read the <source> file corresponding to <target>
+;; 3. Look for 'import <namespace>', where <namespace> is a namespace in the
+;;    aforementioned cache.
+;; 4. If found, then save current build as a continuation and compile
+;;    <namespace>. Result gets put on the dependency stack
+;; 5. When finished, return to building <target>
+;;
+;; Once the build command template is filled out, we can create the nix expression.
+;;
+;; Questions
+;;
+;; - how to import (third-party) dependencies?
+;;   1 just don't have them...? yeah right
+;;   2 the target.nix could be the build description for target.hs
+;;   3 just use a default.nix for the com.whatever
+;;   4 have a deps.nix file
+;;   5 list them in the file with other settings
+;; - how to handle multiple output formats?
+;;   - e.g. that ghcjs and ghc take the same input files...
+;;   - say you have a .md file, you want to bild it to pdf, html, and more. What do?
+;;   - i guess the nix file could return a set of drvs instead of a single drv
+;;
+;; TODO
+;; - stream output from 'nix build' subprocess
+;; - get rid of guile notes during execution
+;; - ns<->path macro
+;; - support list (scheme namespace) in ns<->path fns
+;;

+Start with this:
+  - https://news.ycombinator.com/item?id=14605
+  - https://news.ycombinator.com/item?id=14754
+Then build AI layers on top.
+* Problem
+Developers spend too much time managing database schemas. Every database
+migration is a risk to the business because of the high possibility of data
+corruption. If the data is modeled incorrectly at the beginning, it requires a
+lot of work (months of developer time) to gut the system and re-architect it.
+* Solution
+- Using machine learning and AI, we automatically detect the schema of your data.
+- Data can be dumped into a noSQL database withouth the developer thinking much
+  about structure, then we infer the structure automatically.
+- We can also generate a library of queries and provide an auto-generated client
+  in the choosen language of our users.
+* Existing solutions
+- Libraries like alembic and migra (Python) make data migrations easier, but
+  don't help you make queries or properly model data.
+- ORMs help with queries but don't give you much insight into the deep structure
+  of your data (you still have to do manual joins) and don't help you properly
+  model data.
+- Graph QL is the closest competitor, but requires manually writing types and
+  knowing about the deep structure of your data. We automate both.
+
+* Unsolved problems
+- Unsure whether to build this on top of existing noSQL databases, or to develop
+  our own data store. Could re-use an existing [[https://en.wikipedia.org/wiki/Category:Database_engines][database engine]] to provide an
+  end-to-end database solution.
+* Key metrics
+- How much time do developers spend dealing with database migrations? What does
+  this cost the business? We can decrease this, decreasing costs.
+- How costly are failed data migrations and backups? We reduce this risk.
+* Unique value proposition
+We can automate the backend data mangling for 90% of software applications.
+* Unfair advantage
+- I have domain expertise, having worked on similar schemaless database problems
+  before.
+- First-mover advantage in this space. Everyone else is focused on making
+  database migrations easier, we want to make them obsolete.
+* Channels
+- Cold calling mongoDB et al users.
+* Customer segments
+- *Early adopters:* users of mongoDB and graphQL who want to spend time writing
+  application code, not managing database schemas. The MVP would be to generate
+  the Graph QL code from their Mongo database automatically.
+- Will expand support to other databases one by one. The tech could be used on
+  any database... or we expand by offering our own data store.
+* Cost structure
+** Fixed costs
+  - Initial development will take about 3 months (~$30k)
+  - Each new database support will take a month or two of development.
+** Variable costs
+  - Initial analysis will be compute-heavy.
+  - Following analyses can be computationally cheap by buildiing off of the
+    existing model.
+  - Customer acquisition could be expensive, will likely hire a small sales
+    team.
+* Revenue streams
+- $100 per month per database analyzed
+  - our hosted service connects to their database directly
+  - includes client libraries via graphQL
+  - may increase this if it turns out we save companies a lot more than $100/mo,
+    which is likely
+- enterprise licenses available for on-prem
+  - allows them to have complete control over their database access
+  - necessary for HIPAA/PCI compliance

+#+title: Flash
+#+description: a system for quickly testing business ideas
+
+- Each marketing iteration for a product requires some gear. A "gear" pack is just a yaml
+  file with all data for a single flash test. It will include ad content,
+  pricing info, links to necessary images, and so on.
+  - even better: store these in a database? Depends on how often we need to edit them...
+- Data gets marshalled into a bunch of templates, one for each sales pipeline in
+  the /Traction/ book by Gabriel Weinberg (7 pipelines total)
+- Each sales pipeline will have a number of integrations, we'll need at least
+  one for each pipeline before going to production. E.g.:
+  - google adwords
+  - facebook ads
+  - email lists (sendgrid)
+  - simple marketing website
+  - producthunt
+  - etc
+- Pipelines will need to capture metrics on a pre-set schedule.
+  - Above integrations must also pull performance numbers from Adwords etc APIs.
+  - Will need some kind of scheduled job queue or robot background worker to handle this.
+  - A simple dashboard might also be useful, not sure.
+- Metrics determine the performance of a pipeline. After the defined trial
+  duration, some pipelines will be dropped. The high-performing pipelines we
+  double-down on.
+- Metrics to watch:
+  - conversion rate
+  - usage time - minutes spent on site/app
+  - money spent per customer
+  - see baremetrics for more ideas
+- This can eventually be integrated to a larger product design platform (what Sam
+  Altman calls a "product improvement engine" in his playbook - PIE?).
+  - metric improvement can be plotted on a relative scale
+  - "If you improve your product 5% every week, it will really compound." - Sam
+  - PIE will differ from Flash in that Flash is only for the early stages of a
+    product - sell it before you build it. PIE will operate on existing products
+    to make them better.
