twoslide··on Uber drivers are workers not self employed, Supreme Court rules
Agree that Deliveroo fees seem high on both ends (customer and restaurant). Wonder if this means they (a) they are inefficient (b) they have large profit margins or (c) it is actually more expensive to run than one might think. If (a) or (b), the conditions for lower priced alternatives seem high.
twoslide··on Covid-19: World's first human trials given green light in UK
Interesting, it implies that unvaccinated young people will be exposed to the virus in order to establish minimum levels of exposure required for infection. The BBC article is very poorly written, and based on it I assumed they were vaccinated (and also, I couldn't really see the point).
twoslide··on Covid-19: World's first human trials given green light in UK
Definitely needs "challenge" - of course there have been many "human trials."
twoslide··on San Francisco school board halts appointment based on race
Apologies for making you sad and sorry bringing party politics into this conversation.

Perhaps a more constructive way to say this would bave been:

"I worry that this story may lead individuals to conclude there is a broad pattern of reverse discrimination across the country."

My argument is that there is not such discrimination against White males in the population more generally.

Thanks and apologies again.

twoslide··on San Francisco school board halts appointment based on race
Thanks, that is an interesting point about sentencing that I was not aware of. It is interesting that in the prison population, White groups are under-represented (compared to the population), but it is also true that females are under-represented. [1]. I agree that it is partly about how data are segmented, and probably also about equity is considered (i.e. in the process of sentencing vs across the life course).

I concede the point about sentencing (but not incarceration rates), I suppose some other examples of the institutional sexism and racism I was thinking of would be things like:

- There is a broad gender pay gap (14 to 24%) across the US workforce, even when controlling for variables such as part-time work and parenthood[2] - Fortunte 500 CEOs are 70% white male, whereas the US population is about ~36% male, (based 73% white total). [3] - Government over-represents white males, e.g. about 78% of the House/Senate combined are White and and 24% women [4,5], although this is getting better

My worry is that (political party notwithstanding) some people will interpret single incidents like this as evidence of broad "reverse discrimination." While that is true in this single incident, it does not seem to be true in society considered more holistically.

Thanks again for pointing this out.

twoslide··on San Francisco school board halts appointment based on race
This kind of story is really difficult: it provides fodder for right claims that social justice warriors have taken over the country. As a professor of education, I have some reservations about the decision based on the information I have

However, it is important to keep in mind, that in outcomes that matter most to many (incarceration, life exepectancy, home ownership, high-paying jobs), institutional sexism and racism are real and heavily favor white men.

Both these things are true, but there is some attention bias in omitting the second.

twoslide··on The Queen has more power over British law than we thought
I think we've heard enough about sovereignity in the UK recently to recognize that it is sovereignity is always contingent and somewhat ambiguous.
twoslide··on The Queen has more power over British law than we thought
Interesting, does that mean that the Queen has implicitly agreed to a lot of controversial legislation (e.g. Internal Market Bill, and Brexit more generally), or the process of the proroguing parliament last year? It seems she might be a lot more conservative (lowercase) than many might like to think.
twoslide··on South Africa suspends rollout of Oxford-AstraZeneca coronavirus vaccine
Which overlaps with the CI on other COVID variants. This is a small sample study, and the media and governments are probably too quick to take the centre of the estimate. Sampling variation could explain the outcome as much as the South African variant.
twoslide··on Oxford/AstraZen Covid jab far less effective against SAfrican strain,study shows
This story has been picked up by a lot of media, but really lacks essential information (what does "far less" know). All we know is N=2000 (splot ~50/50%), and no one was hopitalized with COVID in the treatment group. We don't know how many cases occured in each group, and whether these cases were the SA strain.
twoslide··on Myths of Vaccine Manufacturing
This article discusses why mRNA vaccine manufacturing cannot be outsourced to third parties, but there are other vaccines that might be be produced in this way (Oxford/AstraZeneca). Not sure if this is authorized in the US, but it is in many other locations experiencing shortage (e.g. the EU).
twoslide··on Show HN: Haven – Run a private website to share with only the people you choose
A private blog for sharing photos is great, but the suggestion it's a Facebook replacement is questionable. People now use Facebook not only for photo sharing/status updates, but buying/selling stuff, communities, and (unfortunately) news. Notifications such as "Friend A commented on Friend B's post" is pretty impossible in this framework, and it's not really possible to recreate this in a world where everyone self-hosts. Projects like diaspora try a decentralized approach as the next best thing.
twoslide··on Oxford vaccine shows sustained protection of 76% in 3-month gap til second dose
Agreed, important to keep in mind the UK has highest per capita mortality of any large country. But this is good news for the government’s gamble to increase spacing between doses to 3 months
twoslide··on The Climate Crisis Is Worse Than You Can Imagine. Here’s What Happens If You Try
I don't know if it is a question of intelligence or understanding, but rather evidence that there is currently very little demand for climate solutions (because everyone can externalize these costs for free). The lack of jobs on HN in this area is really a symptom of the problem. But also true that their are jobs in this area (solar) they just don't overlap with the typical HN skillset.
twoslide··on Machine learning saves us $1.7M a year on document previews
I just did the same. I moved to Google, even though I’m no fan. Cost is about 70% less.
twoslide··on A 19th-Century Vision of the Year 2000
Reminds me of these BBC interviews with children in 1966, imagining the year 2000 (video): https://twitter.com/BBCArchive/status/946365140642889728
twoslide··on Ask HN: How do we build the new remote education system
It's not really about the most efficient, easily consumable delivery of information from point A to B. Students are really "consuming" a bundle of knowledge, skills, experiences, credentials, reptutation and social networks. There's not much incentive to move online (Prof at a UK university)
twoslide··on Covid: New lockdown for England as cases surge
Yes, but you have a lot more chances to have the bad luck if the virus is spread widely
twoslide··on Covid: New lockdown for England as cases surge
Good point, we’re a small share of global cases. I’ll temper my wrath a bit.
twoslide··on Covid: New lockdown for England as cases surge
One of the things that irritates me most is that Boris portrays the variant as a kind random piece of bad luck. Don't know much about genetics, but I guess such a variant becomes more likely when there are many infections (more of the virus to mutate), and the strategy has consistently been to run things "hot" and tolerate high case counts.
twoslide··on Wall Street Begins Trading Water Futures as a Commodity
That's great you have a plan but this is not really an option for much of the world's population and perhaps they should not suffer lack of water because of this.
twoslide··on Oxford University breakthrough on global COVID-19 vaccine
Also worth noting that we did this by having a board research base that was not tied to immediate returns. A year ago Sarah Gilbert was struggling to get funding for work on the MERS vaccine, which was seen as largely irrelevant.
twoslide··on Oxford University breakthrough on global COVID-19 vaccine
I don't think we know based on public information. Some media report "up to 90%" which suggests the upper bound of the confidence interval, rather than the centre. Could also be a very wide CI, that overlaps with the standard dosage.
twoslide··on Over 90% of Indian techies in the US are upper-caste Indians
It's equally probable to say that the driving factor is caste discrimination, which is the underlying cause of economic inequalities. They are two highly correlated variables, and disaggregation is difficult, but there's no (a priori) reason to assume the drive is economics and the "proxy" is race.

The idea of "it takes a few generations" is also widely critiqued with respect to racial progress in the US: https://www.theatlantic.com/magazine/archive/2020/09/the-myt...

twoslide··on Climeworks lays the foundation to scale up carbon dioxide removal significantly
Agreed that doubling every year is wildly optimistic, other technological growth is much slower, e.g. mobile phones were about 36% annually between 1990 and 2018: https://data.worldbank.org/indicator/IT.CEL.SETS.P2
twoslide··on Climeworks lays the foundation to scale up carbon dioxide removal significantly
True, for another perspective, one way across the atlantic is about 1 ton, so this is 2000 one way trips or (roughly) 10 flights of 200 people.

On the other hand, if this amount doubled every year, it would equal total US CO2 production in 21 years, total global CO2 production in 27 years.

Agree with the other comments that preventing emissions in the first place is far more efficient. Also, I think that CO2 removal is now included in many climate change models, so the benefit might not be too great.

twoslide··on Ask HN: Google Drive/Office 365 alternatives
This is correct. Current legislation (GDPR and the UK's implementation in the 2018 Data Protection Act) does not require data to be stored in the UK. G Suite is definitely GDPR compliant, could the trustee be raising vague concerns without good cause (they do that). There are other reasons to switch from Google, but that's not one of them.
twoslide··on Amazon drivers are hanging smartphones in trees to get more work
It is pretty easy to spoof GPS locations, at least in Android, in a way that is undectable to apps using location services. Might be a better option for these drivers?
twoslide··on C++ Lightweight, cross-platform, HTML rendering engine for desktop apps
If you're writing desktop apps using an HTML/CSS interface, I wonder if "lightweight" is really a concern? I don't work on any such projects, but I'd probably prefer something established with a community (electron) if the only advantage is size (they mention memory usage too, but no specifics).
twoslide··on Mozilla's Speech-to-Text Engine Is at Risk Following Layoffs
It's supposed to work on sentence long audio (4 - 5 seconds), they suggest chunking your audio first: https://discourse.mozilla.org/t/longer-audio-files-with-deep...
