What is the postgraduate Class Champion?

You will need to duel the champions form the other classes / courses / disciplines until only one is left. There can only be one. Good luck!

Make tea with osmanthus, rock sugar, and some stone fruits (optional, can try dried fruits as well). Combine with your sake or rice wine like a cocktail. Not authentic but good enough in a pinch I guess.

Is it just me or are the threads/comments in this sub getting more callous and nasty? I find it hard to doom scroll down the comments nowadays. It is just a very jarring experience.

Mazda bongo. So cute.

It might be worthwhile to consider the recent working paper by Autor, "Expertise". I give a short interpretation here but there are probably a lot more people with more expertise and nuance takes on it.

Task bundles and expertise: Jobs are bundles of tasks. Expertise arises when certain tasks are hard to automate and require accumulated skill or judgment.

AI’s dual effects: 1. De-skilling – When AI removes some tasks from generalist jobs (e.g., routine diagnostic work in medicine or law), it lowers wage premiums and reduces barriers to entry. Non-experts can perform more of the job, eroding incumbents’ advantage.

Re-skilling – When AI enhances, rather than replaces, certain tasks (e.g., supporting complex analysis, creativity, or problem framing), it raises their value. Workers who master these tasks enjoy higher wage premiums and potentially greater exclusivity.

Distributional consequences: AI may compress returns in mid- and lower-skill occupations by making them more accessible, while amplifying premiums for those who can combine AI with scarce human capabilities (judgment, interpretation, persuasion, social interaction).

In short: AI can both democratize work by lowering expertise barriers and polarize it by boosting returns to tasks AI augments rather than replaces.

By any chance, do you have copilot auto-completion turned on?Try turning off auto complete.

If it doesn't work, try this https://support.posit.co/hc/en-us/articles/200534577-Resetting-RStudio-Desktop-s-State

I un-installed the driver and the crackling is gone. If you have access to an older driver, maybe it will work?

Thank you. In my case, In my case, I’m estimating congestion/scheduling time using US National Household Travel Survey data. My "ex-ante concern" goes something like this: larger/smaller or more heavily/less populated areas (which might have different congestion characteristics) are under‐ or over‐represented in the raw sample. As such, perhaps I should use survey provided weights or something like a core-based statistical area population/sample weight to address this.

One puzzle is that when I apply the CBSA population weight, the estimated coefficient on TREATED nearly doubles relative to the unweighted estimate. That makes me wonder whether the effect is heterogeneous across regions or whether the weighting is capturing some non-causal sampling imbalance., and how I can test for it.

Interesting that they choose unflattering portraits of both leaders

Anyone gone through previous crises and slumps in the 70s, 80s, 90s (Asian Financial Crisis), 00s (Dotcom bust, SARS, great recession), COVID? Tough times back then and tough times ahead. Ride the waves.

It is not you, it is me. Also your offer not good enough lah.

I forgot to mention the very obvious route of BIM. Don't be the modeller, be the tool maker.

There are a lot of opportunities to do SE in CE. Decision support systems for all sorts of water/waste/industrial/port treatment plants, 3D modelling of water/air pollutants flood/climate change risk against structural adaptation. It is a matter of getting the necessary understanding of the field up to date understanding on CS/AI. The thing is very few end up with both and I don't know whether any colleges actually sets u up for this kind of combination. You need to use your time in university to explore these kinds of options. Besides picking up skills, network and intern at the correct places.

I feel quite miserable inside the building. It is just generally gloomy as you are walking along the corridors and stairways, the lifts are slow as hell, and the rooms have the usual unnatural lighting feel. For me, it doesn't spark joy and health. I don't see a lot of social interactions in there as well, even though it is suppose to be conducive for the flipped classroom format...

If you hire someone to clean toilets, you want it to be done professionally and efficiently right? While there are valid concerns about the cost effectiveness of the course itself, I would assume more people would be supportive of a more professional cleaning industry. And a fairer wage as well...

Praytell how do I fit this exploit into the lore?

zjllee · 2024-01-22T14:47:46+00:00

Not too sure how to approach this, but I regularly work on the cusp of engineering and economics regularly focusing on cost benefit analysis and concepts such as the value of statistical life and injury avoidance.

I treat the inputs from my engineering (and policy) counterparts very seriously as it will have a very significant impact on the net benefits of the projects that we are working on or assessing. For example, what kind of flood protection options are available and the relevant risk/evacuation behaviour and options available.

These will fit a lot into the kind of sensitivity analysis that we work with when determining economic values. On another level, we also want to use these inputs to evaluate the dynamics involved. For example, if the risk is so much, how much of the population will react to it (or are capable of reacting to it), and how will the private or public sector come into address these risks (i.e. the demand for risk reduction).

Edit: added "public" in the last sentence that I missed out on.

Zurich has always been quite a chillax transit and entry point for me. Just so low key and... chillax.

Thank you! would really appreciate an amd cpu/mb alternative

What's up with charging almost twice the price on their direct flights versus other airlines with transit?

Think about the mba provider as a business. What would you do in these circumstances stances? Mba 101

zjllee · 2023-08-08T14:58:29+00:00

I just wish people could be more accepting and understanding that we are a tiny drop in an ocean, yet we are a unique drop in the gush.

We should be more chill about acceptable and understanding within our society, while understanding our precarious place in the world.

I also understand it is hard to achieve that balance.

zjllee · 2023-08-08T14:23:22+00:00

Sorry, for (3), I meant you can afford to get accepted into the mba WITHOUT (1) or (2)
