roel_v··on System76 Launch Configurable Keyboard with Open Source Code
How do you mean? For both the left and right hand, you extend the fingers, pretty much symmetrically. It's not perfectly straight depending on how the staggering is done, but straight up is worse than all the alternatives.

Because your arm is at an angle to the rows of the keys (with a non-split keyboard), so when you extend a finger, it doesn't go straight up. With staggered keys, you can reach the key on a row up by only extending your finger (i.e, moving it in line with the direction of your underarm), without having to move any other fingers aside.
roel_v··on What’s interesting about the Florida water system hack is that we heard about it
If the power plants would shut down or be severely damaged, wouldn't the resultant lack of power cause all sorts of damage, including things like accident victims not being able to reach emergency services and all the other classic ripple failures? I can imagine there wouldn't be any direct casualties in the plant, but I can't imagine power plants that upon unplanned shutdown would not cause severe damage, including physical harm and death (albeit indirectly). Even power disruptions of a few hours cause deaths.

You can buy tiny usb (in the past, PS/2) dongles (more like pass through devices) that do just that.

Why would anyone want ortolinear layout in non-split keyboards? Do you sit with your elbows scrunched up in front of your body?
roel_v··on CD Projekt Red has been subject to a cyber attack and ransom demand
I wonder if there is a business to be made out of taking these pay to play mobile games and straight up cloning them (not ripping off the graphics, that would land one in legal hot water, but just making the exact same game) and sell them for a one off payment. If there were companies that did that, and they would be known for making high quality puzzle games that are not pay to play, I would buy from them without even trying out their new games (after they gained my trust with the first few games). Technically it would be easy (most of these games are simple), you need graphics people who don't mind just grinding out content without needing to be very artsy, so I would imagine part of the lost revenue that the lootbox companies do get, could be offset by not having to spend a bunch of time thinking about what sort of game you really want to make and make decisions about gameplay etc. Just copy from existing games and sell to the 'don't like pay for play' crowd.

Maybe there just arent' many of us who don't mind paying for games as long as we don't have to buy hearts and diamonds and coins and what not.

roel_v··on I told a cat food company how much they’d save by using taller cans (2020)
LOL I can imagine how this went down when this letter came in at this cat food factory.

Marketing: Hey you engineering nerds. We just got this letter from an actual Professor, saying we can save money changing the designs you made us use for the cans! Fix your mistakes or prove why the way you made it is better!

Engineers: Hold my beer.

So I don't know much about ML; how much better would one expect ML (which I take in this context for 'deep neural network'?) approaches to be compared to a multinomial logistic regression, for applications like this? Is logistic regression old school and/or outdated now?

roel_v··on I'm tired of this anti-Wayland horseshit
The people replying like that are in the barely-not-novice-anymore category themselves, and their mental model of the world is that everybody is just fumbling around doing everything wrong like they were doing themselves a short time ago. It's true that when you are just past the point where you're not totally useless any more, there is a point where you think you're God's gift to the world (not judging - I have felt like this many times over, it goes away after the next big hurdle you run into...), and it's impossible at that stage to imagine the type of abstract thinking you get after many more years of experience.

But yeah - the 'XY problem!' crowd (along with the 'But The Rules!' crowd) has also totally destroyed Stack Overflow.

20000 bees = one small hive. Doesn't make as catchy a headline of course, but just for reference.
roel_v··on Ask HN: What is your “I don't care if this succeeds” project?
I've worked on this in the past too (not as rigorous as it sounds you are). My main problem: how do we define our optimum function, and how do we quantify the variables going into it? How do you do it? I assume you're not sitting there and tasting, comparing and scoring 25 salad samples every 3 days...
roel_v··on What’s Wrong With The Honeywell Humidifier
Well, I thought about building my own, but it's not so easy as you make it seem to get one that is efficient (i.e., not just brute force capacity through size) and easy to use.

- How to make it not look like an animal food barrel in your living room, aka WAF, although I do find that term somewhat demeaning as I get older - I used to not care about such things either when I was in my 20's, but nowadays I do, even if it's just because of the realization that people around me care.

- How to make a mechnism to easily fill it, without spilling. This is related to size - you can have a huge one so that you only have to fill it every few days, but then you'll need to shlepp around buckets or watering cans. If it's smaller, you need a separate tank, which you now have to hook up to the rest.

- How to moisten the wick. It's called a 'wick' because it, well, wicks, of course, but you need a relatively large surface contact area to get lots of water into the wick(s); or you need a pump that will keep vertical 'wicks' wet all the time.

- The fans need to be on the top, and large for minimum noise, but the largest Noctuas are only 20cm. But you need air intake from the bottom, somehow, while still maximizing volume efficiency (i.e., you don't want 75% of the volume of the device to be unused because you can only have water in the lower 25% because of the airflow design).

- You need something that can be cleaned and filled without too much (preferably no) disassembly, and you don't want moving parts like floats or fragile things like measuring water level with metal strips because those will break within a year or two; or faster if you don't have a water softening device in you house.

Overall, I think humidification is a job of proper devices that are part of the indoor climate control system along with heating and cooling, but I don't know of residential systems that combine all, and if they do/would exist, it would be much more expensive than the few 100 at most people want to spend on this, and require extensive plumbing to get installed.

roel_v··on What’s Wrong With The Honeywell Humidifier
If it makes you feel better - my wife insisted on paying 350 euros each for two 'design' humidifiers. Just the replacement wicks they sell are e50 to replace them all. But hey, it does have 5 different fan speed settings...
roel_v··on What’s Wrong With The Honeywell Humidifier
Why? Evaporation humidifier won't make more noise when they're empty, and water level detection is surprisingly hard to make reliable while still being convenient in consumer devices. And you have to refill them daily anyway, so using it as an 'empty' indicator doesn't really add much (in theory it does, but not in real use). At best one could say it's the energy savings, but for a device that requires daily maintenance (refills) I'm not sure if the benefits outweight the advantages.
roel_v··on Robinhood is limiting purchases of stocks: AMC, Blackberry, Nokia, and GameStop
This is not a pump and dump. In PnD, there is an element of subterfuge - the people you are selling to are unaware of what is going on. In this play, all actors are fully informed of what is going on. I mean, maybe some people don't really understand the details, but the majority of people here aren't buying GME because they think it'll keep going up; they all know it's overvalued, but they don't care, because the goal is only partially to make a profit. 'Pump and dump' isn't illegal per se, what is illegal is lying about fundamentals or circumstances to influence stock price. That is not what is happening here.

Furthermore, if you're arguing that it's illegal because it's done in group, then I don't understand what legal basis you are using for that. I also don't understand why you'd say it's "very different" from doing it on your own. I can't think of anything else off the top of my head that legal to do on your own, but illegal in group (some things are more illegal in a group, but that's not what we're talking about)

roel_v··on Robinhood is limiting purchases of stocks: AMC, Blackberry, Nokia, and GameStop
"This is text-book illegal activity."

Is it? If I have the money to put a short squeeze on someone by myself, with my own money, is that illegal? Isn't that what some people do all the time with smaller numbers?

(honestly asking)

roel_v··on I tried to report scientific misconduct. How did it go?
Well yeah in the papers of the OP maybe, I don't know. I more meant to address several commentors in this thread that seem to think in general that peer review is 'redo the research' and/or 'validate that it's correct'. It's not.

Nowadays when you see articles results of new research of covid19 in the media, those articles often include 'hasn't been peer reviewed yet' or 'reviewed by other scientists' or any such verbiage, either as a disclaimer or as 'now it must be true'. But that's not how it works; it's not because something has been 'peer reviewed' that it's 'The Truth' or 'Real Science'. Peer review, in reality, just weeds out (most) quacks (although in the OP's case it seems it didn't even do that) and checks that the paper is not completely out of touch with what is happening in and known about the field. It's not QA of the work itself.

(I don't care to debate if it should be, and if more money should be spend on replication etc, just providing some real world context on something that is quite opaque to and often misunderstood by those not in academia)

roel_v··on I tried to report scientific misconduct. How did it go?
"Peer review" is not "have someone else re-do the experiment". That's just not feasible, especially since reviews are done without pay. It's not realistic to expect people to spend more than a few hours reviewing a paper. That amount of time is barely enough to check for overall conceptual issues and maybe flag some really glaring deficiencies. (And then conclude with 'accepted with minor revisions', those 'revisions' preferably being 'add these three citations to my paper, that'll push your paper into 'acceptable' territory'.)
roel_v··on I tried to report scientific misconduct. How did it go?
Wikipedia itself has descended into the same pathologies you see in 'science' today: a bunch of gatekeepers who, by account of having been there the longest, have set up a moat of rules and 'culture' and such, to the point where newcomers are shut down or drowned out. I'm not saying it's impossible to get in; but only those that sufficiently mould themselves to the existing people and structures will last long enough to become fully accepted. And so the system sustains itself.
roel_v··on I’ve tracked every piece of clothing I’ve worn for three years
TIL: there are men who own 15 pairs of shoes and 15 belts mostly over a three year time span. I'm pretty sure I haven't owned 15 belts in my whole life, nor 15 pairs of shoes since I left college, and I'm in my early 40's...

Not judging, to each his own, I just wonder if I'm the outlier or if he is.

roel_v··on Data Scientist Rebekah Jones, Facing Arrest, Turns Herself in to Authorities
Not sure if you're just trolling now... It's the same as 'arguing' with an anti-vaxxer at this point.

I'm not going to go into detail on the power relationship here. If you're going to deny that a university instructor and a student have a power disbalance between them, and that sexual relationships between them are usually illegal but certainly pretty much always inappropriate and against all policies, I'm not sure what to say anymore.

I linked AN ACTUAL POLICE AFFIDAVID that confirms that this woman not only wrote a lengthy document on their affair, but also how she posted that online, wrote the victim's job about it in an attempt to hurt him, and posted the victim's naked pictures online (among other things). I'm not sure what sort of evidence you would consider valid short of you being there watching it happen. And this is just the AFFIDAVID, there is a lot more out there, easily verifyable from various sources. But maybe someone should call the Tallahassee Police Department, ask for Kameron O'Hara, and verify that he actually wrote the affidavid, as you seem to think that someone forged this whole document including forging the name and signature of an actual office of the TPD (which he is, that's easily verified with a single Google search)?

"and the average person who has no legal background eats it up as the wholesale truth."

That's rather rich considering that between you and me, I suspect there is only one person with a law degree, and it's not you.

If all of this is 'hearsay' and 'made up', where did the mugshots in the OP come from? Let me guess, it's all deep fakes set up by the Cabal, as a pre-emptive move to discredit her in case she would go on 2 years later to become a whistle blower for a virus outbreak nobody knew would happen for at least 6 more months? Please.

roel_v··on Data Scientist Rebekah Jones, Facing Arrest, Turns Herself in to Authorities
Stop spreading misinformation. THE COURT CASE IS LINKED IN TFA, and I linked it again (from another source) above. The article does say that she was an instructor. Not a tenured professor but the person she had the relationship with was her student. All of this is described in the unhinged 300+ page document she wrote where she herself documented in cringy detail how their "relationship" unfolded (WHICH IS PART OF THE COURT CASE).

Just because two people are adults doesn't make a relationship between them not dodgy; think about how bad it is for a doctor to date a patient. The situation here isn't quite as bad (well, if you start stalking a former student after they break up with you, I guess one could also argue that this case is much worse than some other situations where everything unfolds amicably), but still, relationships between people in power and those over whom the power is wielded are not just socially frowned upon, they are recognized as Bad News (if not always strictly illegal) for a long time now.

I'm not sure why you're so insistent on defending if not a sexual predator then at least someone with highly questionable judgement. And again, maybe all of this has little to do with the whistleblower stuff, but there is no question about whether or not it's true that she had an inappropriate extramartial affair with a student, stalked him after he tried to end it and was fired over the whole ordeal.

roel_v··on Data Scientist Rebekah Jones, Facing Arrest, Turns Herself in to Authorities
Yes I know about the Daily Mail's reputation, but the court documents are linked in the post. I don't have PACER access so I can't verify, but this is one that would be very easy to refute. Also, there are many other online sources reporting on this, and they have been for a long time (see e.g. https://www.documentcloud.org/documents/6999800-Jones-Stalki... )

Is all of this relevant to the whistle blower case? Well, it might not be, but this sort of backstory does call up many questions. How did a person with a history of inappropriate sexual conduct with subordinates get a management position in the first place?

roel_v··on Data Scientist Rebekah Jones, Facing Arrest, Turns Herself in to Authorities
Uhm, what is missing from most of these 'but whistleblower!' comments is that this woman is an unhinged stalker who, after having an affair with one of her students, went off the rails and was fired from Florida State University in 2017 for it: https://www.dailymail.co.uk/news/article-8344121/Married-Flo... .

That link has mugshots and parts of the court proceedings, this is not 'slander' from what I can tell.

Now, she might still have been pushed in one direction or another, but she has a documented history of being unstable to the extreme; to say that it seems she has a penchant for attracting drama is to put it mildly.

roel_v··on I ran a crawler to collect posts and comments on Parler
People have been saying that sort of stuff daily for as long as I've been online, 25-ish years. Of course someone will say 'but this time it's different', but I chalk this up to a broken clock being right twice a day.
roel_v··on Sinovac's vaccine efficacy less than 60% in Brazil trial -report
Does anyone know of a good resource that explains what 'efficacy' means for a vaccine, and what can (and cannot) be extrapolated from it? The reported efficacies are (from what I understand) 1 - (n infections in experimental group / n infections in control group). But then I see people draw wildly varying conclusiona from that, most of which I suspect are wrong (e.g. the relationship between 'efficacy rate' and 'group immunity' after everyone is vaccinated). But despite looking long and hard, I can't anyone explaining in detail what such efficacy rates mean (and don't mean).
