Enable Processor Boost Mode Control in Windows

Disable Turbo Boost to Reduce Power Consumption and Heat

Why Do We Need It?

If your laptop’s CPU is running very hot and you’ve tried to undervolt it, you’ve probably discovered there’s no easy way to do so—especially on laptops whose BIOS doesn’t expose those controls. I ran into the same issue with my Ryzen 7 5800H, despite numerous attempts, I couldn’t undervolt because the firmware simply wouldn’t allow it. While it may seem drastic, disabling Turbo Boost is one workaround—and you might be surprised how little real-world performance you lose by turning it off.

Enable PCIe 3.0 speeds for NVMe SSDs on Dell OptiPlex 3060

Out of the box, any M.2 NVMe SSDs connected to the Dell OptiPlex 3060 runs at PCIe Gen 2.0 speeds (Max 5 GT/s; 2 GB/s) so the speed tests look like this:

However, after this BIOS mod, the SSD can reach PCIe Gen 3.0 speeds (Max 8 GT/s; 3.9 GB/s) so the speed tests look like this:

Introduction

This is compiled collection of common Japanese SFXes (sound effects or onomatopoeia).

This collection mostly uses Romaji transliterations. The original version was compiled for general public use but modified later for project-use. Some SFXs may be used in combination with other SFXs; some SFXs, or combinations thereof, may be written separately for emphasis within the same panel (example: do- ki-, ドッキッ ), but can be considered as part of the same action; some use repeated sub-elements or prolongation characters (ー) within them. Because of this, many SFXs can have multiple meanings and are dependent on the action drawn, as well as one's interpretation of that action.

Japanese SFX

Introduction

This is a compiled collection of common Japanese SFXs (sound effects or onomatopoeia).

This collection uses mostly Romaji transliterations. Some of them can be used in combination with other SFXs; some of them, or combinations thereof, can be written separately for emphasis within the same panel (example: do-ki-, ドッ キッ ), but can be considered part of the same action; some use repeated sub-elements or prolongation characters (ー) within them. All interjections can be written differently, usually to indicate particularly strong or repeated stimulation. For example, a cho in isolation is almost certainly a truncated version of chotto, where the speaker was distracted from finishing the word. A prolongation of a character, on the other hand, often implies lazy, harsh, or sloppy pronunciation, or possibly even a scream. Because of this, many SFXs can have multiple meanings, depending on the action drawn, as well as one's interpretation of that action.

Structured logs are way better than normal logs for a whole bunch of reasons, but they can sometimes be a pain to read in the shell. Take this logline for example:

{"erlang_pid":"#PID<0.1584.0>","level":"error","message":"Got error when retry: :econnrefused, will retry after 1535ms. Have retried 2 times, :infinity times left.","module":"","release":"c2ef629cb357c136f529abec997426d6d58de485","timestamp":"2019-12-17T19:22:11.164Z"}

This format is hard for a human to parse. How about this format instead?

error | 2019-12-17T19:21:02.944Z | Got error when retry: :econnrefused, will retry after 1648ms. Have retried 2 times, :infinity times left.

Partly updated June 2023

General caution: Chrome OS is a secure OS by design, but this has at least one key consequence. If you change your Google account password, you will still be required to enter the old password the next time you access each Chrome OS device. Devices are encrypted with that password, so the OS needs to decrypt using the old password then re-encrypt using the new one. If you forget your old password you will lose access to your Chrome OS device data. As always, make sure you keep backups up to date.

Fast User Switching

If you have multiple Chrome OS accounts (Say, work and play), you can quickly sitch between them without logging out:

The response to my first few posts has been much larger than I’d imagined and I’d like to thank everyone for the encouragement.

If you’re interested in building a trading system I recommend first reading my previous post on general ideas to keep in mind.

My first really technical post will be on how to build a limit order book, probably the single most important component of a trading system. Because the data structure chosen to represent the limit order book will be the primary source of market information for trading models, it is important to make it both absolutely correct and extremely fast.

To give some idea of the data volumes, the Nasdaq TotalView ITCH feed, which is every event in every instrument traded on the Nasdaq, can have data rates of 20+ gigabytes/day with spikes of 3 megabytes/second or more. The individual messages average about 20 bytes each so this means handling

Originall From: Posted 2015-05-29 http://ubwg.net/b/full-list-of-ffmpeg-flags-and-options

This is the complete list that’s outputted by ffmpeg when running ffmpeg -h full.

usage: ffmpeg [options] [[infile options] -i infile]… {[outfile options] outfile}…

Getting help:
    -h — print basic options
    -h long — print more options
    -h full — print all options (including all format and codec specific options, very long)
