It looks like you're writing a letter.

[ ] Don't show me this tip again.

Moore's law is "the observation that the number of transistors in an integrated circuit doubles about every two years". For a while clock speed was a proxy for that metric, but it's not the 'law' itself.

So what does it say?

It depends on the definition of tenure... if tenure is defined as a closed interval (i.e. defined only for developers who've joined and then left) then it means that, of the developers who have departed, none had wanted to grow with the company, or the company had let them go. For a startup company this might not be a good sign.

If tenure is defined as the length of time the developer had worked, OR, has worked so far, then it means they have a core group of developers and aren't growing the development team particularly quickly. Again, this might not be a good sign for a startup.

Another part of the problem is that companies aren't incentivised to provide parents with the controls they need. Why can't I block an entire channel in YouTube Kids if I know that they make inappropriate content? I have to block every single video? I would hope any legislative efforts focus on incentivising sensible features such as that, but I'm gonna assume I already know the answer to that wish.

From the article:

   Personally, I think the dichotomy between hypothesis-testing and likelihood-quantification is a false one. The “P=0.05” cutoff we use to “reject” a hypothesis is an arbitrary one. When I read papers, I never “accept” or “reject” hypotheses but rather consider likelihood quantification as a measure of the weight of evidence or a distance of the data from some null hypothesis, as measured by some statistic. I encourage everyone else to consider this probabilistic worldview when viewing our paper: we aimed to quantify probabilities of this system occurring in nature, and P-values were convenient and commonly understood ways of communicating quantiles.

This paragraph does a lot of lifting. Conflating p-values and probabilities is the science equivalent of a code smell.

Because the bank's relationship with its customers, central banks, and society as a whole, is codified in law and not in code. So if you find a legal loophole that's different from hacking the bank to get something the legal system doesn't entitle you to. When the code is the law, a hack is a loophole.

Exactly. And then compare the language used in the Open Letter with the claims they are making. One easy example which seriously undermines the Letter's credibility:

Letter Claims: "Distracts from actual mathematics by having teachers develop students’ “sociopolitical consciousness.”"

Referenced Section in Proposal: "Ms. Ross teaches fifth grade at the Jackie Robinson Academy. She has been focusing on developing her students’ sociopolitical consciousness through language arts and wants to bring mathematics into their thinking"

The letter uses an anti-pattern of redefining something and arguing against the definition, rather than doing the hard work of discussing the actual something. Bringing mathematics into a subject where it can be applied is not 'distracting from actual mathematics'. Whether or not the sociopolitcal consciousness element of the curriculum is appropriate for fifth grade is a red-herring as that's not what's being proposed.

Seems like a rather strong conclusion to be based on guesswork. “CDC didn’t cite their sources for this figure and I don’t believe it” isn’t as catchy a headline though of course.

This is a shoddy article that serves only to undermine efforts to deal effectively with Covid, in return for some clicks and eyeballs.

Firstly, the entire premise of the article is not grounded in fact, it's based on multiple in-conclusive statements and reports. Just read the language in the first few sentences - "almost certainly", "appears to be partly based on", "seems to be an exaggeration". But the article then proceeds as if that were fact.

It then tries to reach unsupported conclusions that feed into a convenient narrative at the expense of an inconvenient reality.

That outdoor transmission may have been low is inseparable from the fact that the general population HAVE been distancing, cleaning, masking and other responses. So to conclude that since "<10% is too big of an estimate" masks should not be required for any outdoor activity is gross.

It signs off by concluding that Britain's drop in death rate since January is based on Britain being locked down indoors and carefree outdoors completely ignores the fact that vaccinations have been ramping up.

If you have a genuine conclusion then you don't need weasel words and misleading logic to tell your story.

FTA they created an abstraction layer that makes the abstracted simulated environment closely resemble the abstracted real world environment, which increased the transferability of the model.

With Skype you're definitely able to receive separate streams from each participant, as I can access them individually via NDI and pipe them into OBS to do live multi-party interviews. You can see the resolution of individual feeds change when their bandwidth drops, and you can choose high/low bandwidth and latency modes for each feed. I would guess Zoom does the same but doesn't provide an NDI feed (yet).

The difference is you can choose when you wear your ID Badge / ring outside of work hours. The potential to have your location outside of work hours (by having readers secreted in places) is an invasion of privacy. Most likely requires cooperation from the 'other venues' and I'm not sure what their value proposition would be, but my lack of imagination doesn't rule out the possibility of nefarious uses.

I have already used it for new projects and was glad I did. Yes there are some teething issues, but the small amount of pain is manageable and the productivity improvements are very worthwhile. I start all new projects with Swift now whenever appopriate.

Have seen a lot of these services, but this is definitely worth checking out. I think Multi-armed bandits are the way to go with optimisation, and just won Startup Asia's hackathon using this technique for a tinder-style app. A lot of people talk about learning from their customers, but few know how to really do it - understanding the math behind what's going on gives me much better confidence when deploying this type of service... Great work sharing it in this way.

Thanks for your feedback - I'll take a look at how we can improve the copy. The idea is that yes, in general you know who is looking after your child - being able to call the with one click is just a convenience. However, in the abnormal case where your child is away from their carer for some reason then the ability to be notified immediately and establish contact with the carer could be the critical difference that stops your child from being another of the thousands of children that go missing every day.

Once you add in the complexity of two working parents and a reasonably large care network - then the conveniences become more valuable as well.

I challenge you on #1/#2 since there was Personal C (PCC) around the mid/late 80s. The version I had didn't have a graphics library though, so I learnt 8086 assembler and CGA/EGA calls (memory is hazy here, but probably CGA) and made my own :)

I was lucky enough to be leant a good C book by a family friend (whoops... Still have it almost 30 years later!!).

But I agree with your overall point that it was much harder to self teach back then. On the flip side however is that now there is so much choice that getting started can be a challenge as there are so many routes to choose!
