  • he Mythical Man-Month: Essays on Software Engineering is a book on software engineering and project management by Fred Brooks first published in 1975, with subsequent editions in 1982 and 1995. Its central theme is that adding manpower to a software project that is behind schedule delays it even longer. This idea is known as Brooks's law, and is presented along with the second-system effect and advocacy of prototyping. Brooks's observations are based on his experiences at IBM while managing the development of OS/360. He had added more programmers to a project falling behind schedule, a decisio…

  • The movement of groups can be heavily influenced by ‘leader’ individuals who differ from the others in some way. A major source of differences between individuals is the repeatability and consistency of their behaviour, commonly considered as their ‘personality’, which can influence both position within a group as well as the tendency to lead. However, links between personality and behaviour may also depend upon the immediate social environment of the individual; individuals who behave consistently in one way when alone may not express the same behaviour socially, when they may be conforming w…

  • Penicillin will be out of your system after your last dose in about 7.7 hours. Penicillin has an elimination half-life of approximately 1.4 hours or less. It takes approximately 5.5 x elimination half-life for a medicine to be cleared from your body which is 5.5 x 1.4 hours = 7.7 hours for penicillin.

  • The necessary and sufficient thought pattern and acronym I use is T SAW TIS P (Tee saw Tis pee), which knits together thoughts from Dan’s book. I often count TSAW and TISP on my fingers when I play (though sadly I am not good enough at chess for people to think I am cheating with mysterious hand signals). Every move, TSAW TISP is necessary and sufficient to play your best. Here’s what it means: Time When is my Trigger 2? Is the move critical? You can check this while waiting for your opponent to move. You know how long t is for your time control, so you can deduct that from your current time l…

  • Just give me the answer With these three principles, we have a practical guide to time management. And, surprisingly, the numbers work out quite neatly. Roughly speaking, if the time control is 10 minutes, we use ~10 seconds per move for the first 15 moves, double it for ~20 seconds per move for the remaining non critical moves, and double that for ~40 seconds per move for the critical moves. If the time control is 5 minutes, it’s 5, 10, and 20 seconds per move. And so on.

  • In addition to these three areas, we have attempted to set up our structure in a way that aligns our incentives with a good outcome. We have a clause in our Charter about assisting other organizations to advance safety instead of racing with them in late-stage AGI development. We have a cap on the returns our shareholders can earn so that we aren’t incentivized to attempt to capture value without bound and risk deploying something potentially catastrophically dangerous (and of course as a way to share the benefits with society). We have a nonprofit that governs us and lets us operate for the g…

  • he first is that there is no real evaluation metric or target for GPT3. Nothing was “solved” when GPT3 was released, in the way that Go or Protein Folding was “solved”. Nobody knew in advance how long you’d have to train GPT3 before it would start to count, and the eerie experience of interacting with GPT3 is not in any way captured by question answering benchmarks. This lack of easily quantifiable measurement is striking in its departure from previous grand challenges in AI. The second is that there are comparatively few people with traditional elite academic machine learning backgrounds in t…

  • Truly dark liquidity can be collected off-market in dark pools using FIX and FAST protocol based APIs
    Dark pool
  • One of the main advantages for institutional investors in using dark pools is for buying or selling large blocks of securities without showing their hand to others and thus avoiding market impact, as neither the size of the trade nor the identity are revealed until some time after the trade is filled. However, it also means that some market participants—retail investors—are disadvantaged, since they cannot see the orders before they are executed. Prices are agreed upon by participants in the dark pools, so the market is no longer transparent.

  • A crossing network is an alternative trading system (ATS) that matches buy and sell orders electronically for execution without first routing the order to an exchange or other displayed market, such as an electronic communication network (ECN), which displays a public quote. These broker-dealers employ computerized systems to match buyers and sellers of large blocks of shares without using the stock exchange. Depending on the particular broker-dealer's system and the type of securities traded (e.g., exchange-listed or OTC securities), these crosses could occur at various times during the day, …

  • Open outcry is a method of communication between professionals on a stock exchange or futures exchange, typically on a trading floor. It involves shouting and the use of hand signals to transfer information primarily about buy and sell orders.[2] The part of the trading floor where this takes place is called a pit.

  • omparison of Price/Time and Pro-Rata Following are few basic remarks about the two basic algorithms and their comparison.[4] Price/Time algorithm (or First-in-First-out)[edit] Motivates to narrow the spread, since by narrowing the spread the limit order is the first in the order queue. Discourages other orders to join the queue since a limit order that joins the queue is the last. Might be computationally more demanding than Pro-Rata. The reason is that market participants might want to place more small orders in different positions in the order queue, and also tend to “flood” the market, i.e.…

  • Benefits In review, tokenization could provide: Greater accessibility from fractionalization, faster settlement which creates more liquidity and the ability to use collateral across different time zones. Faster settlements for quicker asset turnover and, as a result, higher liquidity. This could help financial institutions move from the current T+2 standard to a near real-time settlement. Assets can be traded, settled, and used as a collateral on the same day‒significantly increasing the velocity on money that leads to wide range of economic benefits. Higher efficiency due to simplification an…

  • The Boltzmann brain thought experiment suggests that it might be more likely for a single brain to spontaneously form in a void (complete with a memory of having existed in our universe) rather than for the entire universe to come about in the manner cosmologists think it actually did. Physicists use the Boltzmann brain thought experiment as a reductio ad absurdum argument for evaluating competing scientific theories. In contrast to brain in a vat thought experiments which are about perception and thought, Boltzmann brains are used in cosmology to test our assumptions about thermodynamics and …

  • A theory of change is the opposite of a theory of action — it works backwards from the goal, in concrete steps, to figure out what you can do to achieve it. To develop a theory of change, you need to start at the end and repeatedly ask yourself, “Concretely, how does one achieve that?”
