> Complaining about messy data... welcome to the real world.

I mean, that's the crux is if you have bad data you will have bad results. Data cleanup/transformation is key for anything (reporting, etc...) and not just limited to ML because it's sexy these days.
You can redistribute the source, and that's what really matters. No one ever made any claims to redistributing binaries, and that's neither the letter nor the spirit of th GPL.

The GPL is about user freedom, which relies on source code. The whole thing came about because Richard only had access to binaries for that printer.

And it makes sense that RedHat wouldn't want you to distribute their binaries...who's to say you didn't backdoor them? That's their name on the line, too.
I think that's the exact problem to which GP poster is referring: tracking only knows about URLs visited but not purchase history. A visit to the product page "vacuum cleaner WheezyMatic 3K" will get you flagged as interested in that product and you'll get shown ads for it — even though you already bought it on the original site.
That's very true, but in practice these corporations argue that that particular paper is their copyright, not the research. Thus, just because the general public need to pay to access a particular document, that doesn't mean they are barred from the research.
PCA has specific use cases. It’s not a catch all dimensionality reduction technique. You can’t use it effectively, for example, if things are not linearly correlated. There of course many tools for addressing many problems, but as the title states, this is often a grind. For any practical problem, exclusive of huge black box neural nets where you don’t need to understand the model, you are probably better off starting with a smaller set of reasonable sounding features and then slowly growing out your model to incorporate others.

Also if you meant random forest by forests... those aren’t especially reproducible. Understanding what’s going on is not always easy, and most people seem to misinterpret the idea of “variable importance” when you have a mix of categorical and numeric features. Decision trees and linear regressions are nice and reproducible.

There's nothing wrong with having good workmanship in the things you produce. More so for the things you enjoy doing.

If you enjoy writing these abstractions, then knock yourself out. You said "hobby", right?

Personally, I'm slightly against this type of thing.. abstractions/modularity for the sake of it. An abstraction for a single concrete thing is actually less readable. A good goal would be to design/write so it can be abstracted later (if required).

GoF is an excellent guide, but it's not a rule-book.
85.7% is very high, that'd be a great gross margin (revenues - variable costs, such as compute/network costs).

I think you honed in on a key issue: "pick a provider".

There's nothing wrong with the current "arrangement", but there might be a lot wrong with the way the arrangement came to be.

Or said another way, there aren't any ethical issues with WeWork renting a building from one of the owners in an above-board lease arrangement. The way WeWork chose that building and reevaluates its lease may have some issues.
Most properties you can book on Airbnb are also available on Expedia's HomeAway. And it's already publicly traded. Also many of the same apartments are advertised on Booking.com. Both of those services were running before AirBnb came. So Airbnb's main advantage is that it made short-term rentals more consumer friendly and populated the idea to hosts, who might not have done it professionally before (which, if you ask me is a bad thing, as I've checked in into so many properties run by hosts who have no clue how to provide B&B services).. anyway.. Airbnb IPO? Yawn.
Why do weird niche websites need more tracking? I'd assume their user base is way more specific, and thus can be targeted better without needing tracking. That I visit the NYT tells you way less about my interests than that I'm reading your blog about aquarium filters.

It is possible for advertisers to configure it so that this does not happen (in theory), but a lot simply do not bother.

I've seen some compelling case studies that it does work, and even at low conversion % for big-ticket items (like hotels etc) it's insanely cost effective.
there are many open source solutions for running a journal. and even low cost publishers that run them.

for manuscript submission systems, github has a dozen of projects. Elseviers manuscript system is not sophisticated in any way.

but that is not enough to make a new journal successful

Your idea has merit however, if a well known name such as google offered something like a "free journal platofm"
It is a product of personality. It takes a certain amount of risk aversion to risk everything to start a company, but that isn't what this is about. This is about investment and it takes selling yourself to convince people to give you money. A good sociopath lives for convincing people to give them what they want without reasonable limits.

Fortunately, most people are not sociopaths, but unfortunately most of these people will not achieve the successes you described.
After a host made a suspicious/creepy comment about our stay, I started logging into host routers (creds usually printed on the device) and look at what other devices are connected. The camera may not be on that network, or not networked at all, but it’s a little peace of mind.

So the solution is obvious. Mix 1 part brine with X parts seawater before releasing. Oceans are big, so X can be a very large number, if that is necessary.
My first car, an Alfa Romeo 75 (aka Milano) broke down on the highway. Engine siezed--the car had a timing belt issue earlier from lack of maintenance. Found a clean Volvo 850 being sold privately. Met the guy who was very pleased to deal with me. He threw in a set of nice Nokian (yeah they made those too) winter tires and sold it to me when there was a better offer because he didn't like negotiating with the other buyer. The car was clean--he and his wife would hand wash it every weekend for the life of the car.

So as we're finishing the transaction, he sees my engineering ring and asks about it. Yes, I do software. Hmm, he asks if I could help him out of a jam. He needed someone to add a print function to a Windows NT app. I say sure, I'll take a crack at it. He shows up that weekend with a laptop all set up with a dev env and source code. Figure out how to do GDI printing stuff and get it done. When he picks it up and sees what I did, asks me if I want a job. Worked as Director at that telco spin-off consulting place for years.

Another fun story is how when roommate of mine was interviewing for a company I interned at, I joined them for the interview because it was done over lunch due to scheduling issues. At the end of the day, I drop by their interview room to see who else is around to say hello to. The VP of R&D is there with a job offer in an envelope. I don't know how they expected to be seeing me that day. Good thing though, I was dragging my feet applying for grad job interviews.

In general, I haven't looked for jobs, they find me one way or another (pre LinkedIn). I did once submit an updated resume--after I was hired.
According to your own linked article, target does not store the PIN numbers.

What happens is, the PIN pad encrypts the PIN code and other payment info, using a key known only to the card issuer (i.e. VISA). This encrypted data then finds it way to the card issuer (e.g. Visa) for verification via one of a few possible paths, either PSTN dialup, or more common these days, over the internet. In the Target incident, hackers grabbed this data as it was being transferred over the LAN.

(For completeness, there are many more organisations this encrypted data passes through between the merchant and card issuer, but nobody but the card issuer can decrypt it)

Also, it's incredibly off topic for the post. I'll bet that's why your getting all the downvotes.
Citizens United overturned a recent law. People were calling the law unconstitutional when it passed. And nobody serious says the New York Times doesn’t have free speech rights. That has been protected by previous rulings.

Right, but even then it raises a conflict of interest, and probably shouldn't be handled by the CEO directly.
The practice is questionable at best, but it's a good reminder about that everying sent with radio waves can be picked up by others even if they were not the intended recipients and no matter if you want them to or not.

It's pretty much like leaving the front door unlocked -- it would be unethical to use it to go inside and steal your stuff but we still need to lock the door if we want to reduce the chance of someone stealing your stuff.

Tips for avoiding this:

- Change SSID at least once per year.

- If your router support multiple SSID's, turn the current one off and use the next one in the settings instead -- it will usually result in the MAC address being changed as well.

- Do the above whenever you move the router from one location to another.
175 usd? I am used to well written and dense tech books being expensive but this is really high. For half I would’ve ordered because I like APL and am curious.
I was applying for my first real tech job as a help desk/sysadmin/LAMP stack admin role at a webhosting company. I had some experience doing a bit of this type of work on my own, but by no means was I an expert.

During the interview I was asked something like, "Can you explain what the LAMP stack is and what each piece does?" I gave my answer but when I got to MySQL I prounced it "My-Sqwill." The interviewer kind of gave me a funny look, chuckled a bit, and said, "Do you mean, 'My-Sequel'?", I gave the excuse I didn't know what the word was because I never heard anyone say it.

I walked out of the interview pretty defeated, but a few days later I heard back and got the job.

A month or so in I was speaking with the interviewer and he said, "Do you know why I hired you? Because you mispronounced 'MySQL' and said you didn't hear anybody say it out loud, but you could still tell me how it worked, what it did, and how to use it. To me that says you were mostly self-taught."

He was right and huge props to the interviewer for recognizing that.

> and were funded, since the beginning, by the Office of Naval Research and the NSA. In fact, the article goes into this extensively, and these facts are not in question:

You'll be hard pressed to find someone working at a major university that hasn't (directly or indirectly) received government funding for something. You'll be almost as hard pressed to find a major tech, freight, medical, agricultural, transportation, aerospace, natural resources company etc that hasn't had (or doesn't have active) government contracts.

That doesn't mean everything is a government conspiracy to spy on people.

Good unit tests (like doctests) also provide superior documentation and examples.

Sure, worrying about documentation too soon is bad, but sometimes when doing early research, getting details clarified and written down is paramount and tests, maybe even unit tests, are a nice tool to have when you want it.

Here's an interesting 2nd order effect:

I switched off most of the stuff I could after GDPR went into force, so at first glance it seemed that I started getting trash.

That was until I saw a banner with a unappealing gray background with a fragment of a poem.

It was an ad. For a poem. This one specifically:
https://thelastwhy.ca/poems/2009/7/12/age-of-asininity.html?...

No way in hell I would discover such a thing had my ads been targeted and personalised, since those usually are reactive, so they show e.g. stuff you recently bought(meaning: been searching for recently).
But it still perpetuates a class system whereby having money and influence yields (potentially) more money and influence. Main Street investors who will have no say at scale should not be excluded from participating in the wealth creation.

Certainly this is not a natural or easy problem, it requires a values analysis of our goals and principles. But if we truly want the market to evaluate a company, we must ultimately allow that market to change the fate of a company. The dual class shares prevent that, which I agree should be listed differently or restricted.

For example, if dual class shares were always subject to a confidence vote by the other shares once per 5 years, this is fine. Or you say that after 20 years the dual class must be dissolved. Allow the use for initial listing, but not forever. I think the author of the linked speech painted a very good picture of this.
In general privacy law seem to work under the "expectation of privacy", which is why you see signs warning of security cameras or monitors showing what they see.

In a rented room scenario, you obviously have an expectation of privacy up until someone tells you explicitly that there are cameras in the space, at which point I guess you can decide whether or not you want to stay there.

So in this case (and depending on local laws, obviously) it seems like the renter would have to convince a judge that the photo of the room with a white blob in the corner was enough notice to circumvent that expectation of privacy.

A couple notes, as my father owned and sold two carpet cleaning businesses.

$100/hour is actually fairly standard/reasonable. My father always shot for $150/hour as his standard rate (he had no employees). 30 years ago he wasn't making this but for the last 10-15 he was.

The assertion that his supplies and overhead are essentially "nothing" is hilariously naive. I watched his video, he has equipment, not to mention the other costs of running a small business (insurance etc.) I get that he's just starting but it's just silly to assume no overhead if you're looking to emulate.

Reading further, he says "I think you can get started for less than $15k". Expect to spend at least that every year.

Cleaning floors is hard work. Much of my father's focus in the later years was spent on reducing fatigue, and streamlining the services offered. It's good, decent work, but not easy physically and mentally (worrying about equipment failure)

Lastly, my father worked for some restaurants. The % of restaurants that never clean their carpets is huge. There's a good chance that most of your local restaurants have never cleaned their carpets.
I often get targeted ads for upcoming shows in my area. Just because you have identified that you like a subject does not necessarily mean you have spent all the money you are going to spend on that subject.

Because a civilized, compassionate society takes care of all its members, no matter how broken they are.

And because, furthermore, various studies have shown it to be cheaper to address problems like this before they get that bad than it is to let someone fall through the cracks. At that point, they're likely to be a cost to society in different ways, whether it's due to crime or just the trouble of cleaning up after them.

"State power" isn't a swear word. It's a highly effective solution to a great many societal problems, when exercised sensibly.

From https://www.gnu.org/philosophy/free-sw.en.html:

"Freedom to distribute (freedoms 2 and 3) means you are free to redistribute copies, either with or without modifications, either gratis or charging a fee for distribution, to anyone anywhere. Being free to do these things means (among other things) that you do not have to ask or pay for permission to do so.

The freedom to redistribute copies must include binary or executable forms of the program, as well as source code, for both modified and unmodified versions. "

If you're in the EU it does not. You can record anything you want in the privacy of your home but if you record other people, they need to consent to it. The reasoning described in the article "but there's a camera in the picture of the room so you agreed to it" certainly wouldn't hold up under any interpretation of the GDPR.

Also even if it's your home, if you rent it out, that's a commercial activity even if it's your personal residence.
No, YOU are the pain to the neighbors. You are probably ruining their family life for a few extra bucks. The neighbors are fighting prostitution, you are facilitating it!!!!
The European Commission (EC) has been funding zenodo.org[0] for some years now, which is an open-source publishing platform[1] built on an open-source digital library framework[2]. While its main focus is providing free hosting and serving as a publishing venue for scientific data and results in order to enable reproducibility of the research, it can also be used (by anyone!) to "publish" their research (or just about anything you'd want to publish).

While I guess it's not technically a journal as there's no editorial or review process for what gets published (and absolutely no prestige associated with publishing on it), everything is assigned a DOI number which you could use to uniquely identify it for citation purposes.

The story behind it, as off-handedly told to me by the then-project manager back in 2015 when I was working on it, is that it was created after the EC had mandated that some percentage of EC-funded research results be published in open-access and the instutions which received such funding complained that there existed no proper open-access alternatives for them to publish in.

I used to use AirBnB all the time. Lately I've switched back to using hotels almost exclusively. The camera/privacy thing is a big part of it. I empathize with the hosts to a degree - you don't want people doing outrageous things in your home. But the hosts want their cake and to eat it too. Don't rent out your home if you don't want the risk of people damaging it!

(As a minor aside, I've also noticed the quality of the places I've found on AirBnB has gone down. The homes I stayed at before I quit using it were not very clean (despite the fee!), things were broken, key retrieval was a pain etc. Hotels used to be much more expensive, but price/quality of experience is starting to get more competitive)

It's funny to me, because AirBnB runs in to all the same problems we had with hotels a hundred years ago. We have dozens of taxes, rules, regulations, building codes etc now for hotels. I imagine at some point it will be the same for AirBnBs. What's old is new.
