Tool for bias detection, visualization, and mitigation in ML models
I am a developer of R package fairmodels which facilitates dealing with biased models and ensuring that the model is treating certain subgroups similarly. It is flexible, works with many models (even from different packages) that can be later compared with each other. For a long time, such a tool wasn't available for the R community. I would be more than happy to receive feedback and critique if you want to check it out.

So far there I wrote a blog post on medium and on R-bloggers.

> It seems to me like a time series or sorting problem. The challenge was inserting meta data and then sorting.

The core problem, as I see it, is missing asset identifiers. The timestamp of each asset in the Kafka queue acts as the ID.

This is an ETL and data cleansing task. My first step would have been to use a Content Addressable Storage technique, like Git hashes, to assign a unique identifier to each asset which also solves the de-duplication task. Extracting content metadata, like true publication date, and inserting into a structured data store then follows.

Kafka should have been one part of the ETL pipeline, not act as the structured data store itself.
100% agreed, JSON fields are good when you want to dump a bunch of data you don't care about the shape of, but if you need a schema, pull the data into actual fields.
That really depends on where you live. Over here, most people ride bikes regularly. Car headlights that can blind cyclists should be considered a serious issue.
Can you explain it, because even after reading the about page I think your objections in the first post stand unchallanged.

> Half measures are exactly how we got to this point

also they increased the maximum stabilizer angles mcas could command, the review/certification was done with a 0.6 cap (effective but not overwhelming) and on production it was increased on a whopping 2.5 degrees.

it was also meant to be using vertical acceleration to understand whether the plane was actually stalling, but that trigger was removed

it was also supposed to operate slowly enough to let people catch up with its operation and be able to disconnect it in case of a runaway trim, but the increased angle required to move the stabilizer faster

I don't know the exact English term for this kind of iterative failure of people communicating changes to each other assuming they are both fixing a problem, instead making it worse, but it's not just like they were doing half measures, they were each tuning their systems in silos, without considering cross system functionality from each system behavioral changes
What are you blaberring about? I agree that these luxury watches are mere status symbols and not a necessity, but no one's selling them at 90% margin. A considerable amount of highly skilled exclusively first world labor goes into these watches, and these devices are probably the single best type of objects where the labor that went into it is patently obvious right in front of your eyes. In fact, that exactly IS the symbol here for the most part, the fact that it's a human creation whose value is purely of the labor (the good kind) more than something that came out of the earth, and something, all considered, that holds its value over time instead of being ephemeral. I understand the angst and anger against the plutocracy but logic needn't go out the window in pursuit of an outlet for that anger.

people generally claim that Comic Sans is helpful for dyslexia - I think that is the default view (for anyone who considers accessibility of the font, most people just hate on it ) https://www.arcstone.com/blog/designing-for-accessibility-dy...
however there have been some recent arguments that the studies as to if it was actually helpful for accessibility are dubious https://www.tes.com/news/does-comic-sans-help-dyslexic-learn...

The it's dubious argument seems compelling but I still tend towards the it helps belief probably just because I have spent some time thinking the first argument was true and the second argument has not yet managed to win through that habit.

> Are you speaking out of professional experience? Do you know of cases where not implementing accessibility really did become a big financial hazard?

Not sure what are you saying here. Are you saying that while it might become a law, companies that can't find the money to comply don't need to comply in such cases..? Or that it hasn't happened yet, so it's not bound to happen?
But not everywhere. There are still plenty of places, especially on smaller, sometimes less-well-lit roads, where bikes share the road with cars.
Myth and Monolith – The Nine Elms Cold Store
I’m in a process of building 1MW in Poland, and - at least here - it’s not true that renewables are not commercially viable.

That is, if I finished building today and began trading on an open market, I would benefit more in the upcoming years (possibly overall), than through auctions.

The benefit of auctions is that since they guarantee the proce for the next 15 years, it’s way easier to get financing for them.

Our estimates show that we would have way higher returns on the open market, but the risks would be much higher as well.
Well, how would you know?

Only if your DB is purely a way of keeping your objects warm, otherwise you can design your DB with the business in mind, the app with the apps domain in mind, and an adapter between the two.

I understand the layoffs in Airbnb and the airlines. But I'm not sure I can justify the layoffs in linkedin. If anything there are more people looking for a job than before so I'd guess more people would go for the premium (paid) service at least in US.

I found it pretty curious that the voiced dental fricative was used to represent 1 but the unvoiced dental fricative was used to represent 8, seems like the only voiced/unvoiced pair to be split in this way.

In my idiolect, they both belong together with the alveolar plosive pair (/t/,/d/) in category 1. The place of articulation feels almost identical between my laminal plosives and dental fricatives.

Though I do agree with grouping the velar nasal along with the alveolar nasal rather than with the other velar plosives. The acoustic similarity between /n/ and /N/ feels a lot more salient than any similarity in velar articulation.

Overall, a really cool system! Now I'm curious about what kind of density you could reasonably encode if you remove the need to memorize and used it as a form of steganography.

Many of these watches are Swiss. Switzerland is (or was) a known tax-haven...

It's our inability to connect the dots that baffles me sometimes. Where else do the wealthy elites get the kind of cash needed to buy these watches?
Not a complete answer but at least they have made some effort to consider this.

It makes sense, the game devs saw how well the FnF movies did and wanted a slice of the pie.

It worked out so well because it gave people a way to experience car modding and illegal street racing in their own living room. If people are getting their kicks from street racing games... maybe we should make more street racing movies.

I remember having worming pills as a precaution as a child in Australia, and was also later infected with threadworm at least once so had medicine for that. I did walk around outside without shoes a lot back then.

But from what I've seen in research and been told by doctors, they see no reason to worm adults as a precaution. I'm not sure what the supposed downside is of doing it once a year or so - nasty side effects?
The median bus journeys is probably about 20 minutes long since intercity journeys are probably dwarfed in number by city busses, so I'm not sure per journey is the best metric here. Per hour or per KM seems better, or possible take a weighted average of all three.
> state of the art in nowadays OSS

I agree with that, in fact it has been for quite a while. There are lots of OSS projects which have companies selling proprietary extensions for. For example, The Qt Company sells a proprietary plugin that automatically generates QML from Photoshop designs. Most people are fine with that because it is a very niche feature and not something that is the value proposition of the OSS project (Qt in this example).

OTOH, the OP feels like LiveShare, Remote and Marketplace are VSCode's primary value proposition - in which case it is fair to object to it being marketed as OSS. (although I personally consider only Marketplace to qualify)

The thing is it kinda forces me to read the text word by word and makes it much easier to correctly read the words.

I'm very minimal reading dyslexic (it's a bit complex).

Anyway while it doesn't fell like it would allow me to read faster, I believe it does help me to read more correct. Through I have to test it out more. I thing I will try it the next time I write a paper or similar. Also it's very different to many other font's so maybe it's just about getting used to it?

For a database like postgres, or even for something like SQLite, this mostly becomes a distinction without a whole lot of difference, since the database can index and access JSON structures just like regular columns.
You don't need to hire a blind person to be compliant with regulations. What if you are building consumer facing products? Can you pick who your consumer will be?

What if the employee were a medically fit person but met with an unfortunate accident and lost his/her eyesight/limb and have to now continue job after recovery? How can s/he continue their job? Will you fire the person? You never hired a physically challenged person but s/he can always become physically challenged due to some accident later.

I find the "short-circuit" is confidently rejecting the notion of "socially imposed norms" but appreciating the subtle ones.
A funky dress shirt at an event when most are suit and tie (not required but socially imposed) without giving a wink about it - rejection of the norms. Strong handshake with a suit, mentioning their watch, speaking their lingo - appreciating the subtle ones. That short-circuits people's expectations and the rejection of the "socially imposed norms" seems to be perceived as more of a status symbol then following them is. Humans both love patterns and anomalies, so an anomaly that fits in the pattern seizes their interest.

For security reasons, contactless card payments are limited to small transactions and can only be used a certain number of times between chip and pin transactions.

Since it lacks a second authentication factor the compromise is to limit how much can be spent if the card is stolen.

The US could skip chip and pin if it switched directly to contactless mobile payments.

Interesting; I learned a slightly different set of associations with mnemonics for the sounds as well. 0, 2, and 3 were the same as this system:

0 = the word zero has an s/z sound
1 = a single line, like lower-case "L"
2 = two lines, like lower-case "N"
3 = three lines, like lower-case "M"
4 = the word "four" ends in an "R" sound
5 = the word "five" contains "F" and "V"
6 = the digit looks like a lower-case "B", and lower-case "D" is its mirror image
7 = the digit looks like a badly-written upper-case "T"
8 = the "gh" in the word is weird, and reminiscent of "CH"/"SH" (and "J" is similar)
9 = the digit looks like a lower-case "G", which is similar to lower-case "Q", and lower-case "P" is its mirror image

I had no idea that there was a standard, but I use it a lot to remember what page I've reached in a book (without a bookmark handy), or for short strings of numbers like IP addresses. I find it much easier to remember "Latin insults suns lamely" than "172.217.20.131", though I'd probably try and find a better mnemonic than "insults" for 217, as that technically maps to 20170...

It's kind of like the "correct horse battery staple" thing (https://xkcd.com/936/); words are easier to memorise, especially if you can create a narrative, however tiny.

The main way SQLite is used around the world is as a library component of a larger application. The main way people use VS code is through the proprietarized official build that uses the official EULA.

Also, lots of people seem to value the proprietary extensions a lot more than people value the encryption extension of SQLite.

I wonder if that implies that neanderthals had greater pain sensitivity in general.

Pure speculation but it would be interesting if that was related to the apparent harshness and difficulty of life at the time. Perhaps it was something selected for survival.

You do know that the Global North is hoarding IP, and that another world of Commons-based peer production is possible, right? We could all be 'well paid craftsmen' if we shifted to that. In my eyes, you're showing an incredible privilege here, being aware of, and talking about, Patek watches.

The component architecture is much more advanced than Godot and you have access to a huge number of components. Extending these components or creating new components is also very easy.
I had to change my mother tongue from Italian to Portuguese when I was 6 and it was kind of strange, but after a while it simply felt normal except for a couple of things.

I'm not dyslexic but sometimes it is hard for me to focus on long texts, I keep skipping words and going back and forth... although I can read quite fast sometimes I read a word for another, when I was a kid it took me quite some time to correctly visualize that "already" is written like that and not "aldeary" and the same thing for a small number of other words. (thanks Baldur's Gate, thanks Ocarina of Time)

When I first opened the site with www it simply felt like a normal sans-serif font (as it was), after reading luisroy comment I changed to the site without www and I must say that it is way easier to read... don't know if it's the spacing or something else, or maybe I'm dyslexic, who knows...

Interesting though :)
Access, but not constrain or type-check.

And it's just harder to use, I'm with it being generally a 'mistake' (in the 'you will regret this later' sense) - it's better than text, but I'm in the camp of as much structure as possible ('you will thank yourself later').
You're just stating the obvious. Just because you can do something doesn't mean you should.

Well the ONS (which is a part of the UK govt) has been detailing the all cause mortality rate and detailing how and why those numbers differ from the official PHE numbers. The ONS releases its findings to the press, and the BBC is just one of many that report on these figures.

As far as I am aware there is no such thing happening in Iran.

So in the case of the UK the BBC is saying that UK govt response has been poor, and in the case of Iran that there is a "cover up". I would have thought that was bordering on a reasonable job of reporting the facts.

If you're taking trip, you can reduce your likelihood of death by either choosing your transportation to and from the airports or choosing your airplane for the flight itself. Given how bad the crash rate of 737 MAX was, it would be prudent to focus on choice of airplane, rather than choice of grand transportation.

The correct comparison isn't "airplane vs. bus" it's "A320 instead of 737 MAX vs. bus instead of car".
