LLM Introduction: Learn Language Models

Purpose

Bootstrap knowledge of LLMs ASAP. With a bias/focus to GPT.

Avoid being a link dump. Try to provide only valuable well tuned information.

Prelude

Neural network links before starting with transformers.

import lldb
def __lldb_init_module(debugger, internal_dict):
debugger.HandleCommand('command script add -f SwiftPrinter.printer pjson')
def printer(debugger, command, result, internal_dict):
debugger.HandleCommand('p print(String(data: try! JSONSerialization.data(withJSONObject:' + command + ', options: .prettyPrinted), encoding: .utf8 )!)')

Making efficient use of the libdispatch (GCD)

libdispatch efficiency tips

The libdispatch is one of the most misused API due to the way it was presented to us when it was introduced and for many years after that, and due to the confusing documentation and API. This page is a compilation of important things to know if you're going to use this library. Many references are available at the end of this document pointing to comments from Apple's very own libdispatch maintainer (Pierre Habouzit).

My take-aways are:

  • You should create very few, long-lived, well-defined queues. These queues should be seen as execution contexts in your program (gui, background work, ...) that benefit from executing in parallel. An important thing to note is that if these queues are all active at once, you will get as many threads running. In most apps, you probably do not need to create more than 3 or 4 queues.

  • Go serial first, and as you find performance bottle necks, measure why, and if concurrency helps, apply with care, always validating under system pressure. Reuse

How to symbolize OSX crash logs

How to Symbolize OSX Crash Logs

Unfortunately, xcode does not yet have support for importing OSX crash logs and symbolizing them. Therefore, you must use the command line and a little bit of manual work.

  1. Find your dSYM file.
    1. Assuming you are using xcode's archive functionality, open the Organizer window from the Window menu.
    2. Click the Archives tab.
    3. Right click on the appropriate build and select Show in Finder.
    4. When Finder opens, right click on the selected archive and select Show Package Contents.
    5. Navigate to the dSYM directory and copy the appropriate dSYM file to a temporary directory.
  2. Then navigate to Products, then Applications, and copy the app file to the same temporary directory.
