I think the emphasis on requiring everyone to be physically present in a noisy, distraction-oriented open plan office is a direct confirmation that it’s about optics and cosmetics.

The decision isn’t driven by what would be productive in terms of work output, nor what would be healthy, nor even what would be cost effective.

They are willing to pay premiums in terms of the costs of lost productivity, costs of opulent office features that don’t increase productivity or attract talent, costs of artificially reducing the candidate pool by excluding remote workers from consideration, etc.

The only way to see it as a rational choice on the part of management is if they are compensated more for the optics and cosmetic appearance of the company workplace than they are compensated for actual work output. I’d argue this seems at least plausible for a lot of start-ups seeking hype-driven investment.

By the formula, it then leads to a cookie cutter pattern of levering up the hyped private valuation followed by a race to an IPO and marketing campaign to distract everyone from loss growth and poor profitability prospects, to use the IPO to essentially externalize the losses that will come from a huge price correction out onto unwitting people who come to own the stock through some unmonitored 401(k) plan manager and onto employees who get trapped by IPO blackout windows preventing them from selling at the early, hyped IPO prices.

Spotify fit this pattern very well, and it is shaping up to be Uber’s strategy over the next year too, while possibly even letting privileged insiders participate in a private equity sale to a few hedge funds, to capitalize even sooner on the hyped private valuation prior to the inevitable price correction.

Really, it’s not hyperbolic to point out that even early choices to mandate an on-site only policy in a cost-ineffective open plan office are indicators of this optics-first-productivity-second way of thinking.
These days I would not use any cipher pushed by any government unless the entire design process itself was done in the open. Chinese and Russian ciphers inspire even less confidence.

The cryptographic community used to have a lot of trust in the NSA, and that trust was well-deserved. One of the most well-known contributions was improving the resistance of DES to differential analysis, which hadn’t even been discovered in the academic world yet. The NSA recommended an S-Box change, and provided next to no rationale for doing so. Only years later did we understand why.

Recommendations from the NSA find their way into standards that are implemented by the government itself, and that is one of the reasons the community trusted the NSA to a degree. It wasn’t seen as being in their long-term self-interest to insert backdoors that others could find into their standards.

Obviously that trust was wiped out by the DUAL_EC_DRBG debacle, although many cryptographers still believe it’s worthwhile to analyze and consider NSA ciphers on their own merits just as you would a cipher by DJB.

In my personal opinion, as a general rule, I would wager that symmetric ciphers published by them can be reasonably assumed to be free of back doors, since there’s fewer degrees of freedom to insert them except through real cryptographic weaknesses which others could independently discover. Asymmetric algorithms probably shouldn’t be given this benefit of the doubt, since there are enough degrees of freedom to be possible to have a private master key of sorts (e.g., DUAL_EC_DRBG) which isn’t be able to be discovered independently and can only be revealed if it’s stolen directly.

This was the first strategy game I played, I think on a Windows 3.1 486, and I was generally awful and had to use very cheap tactics for almost all the levels beyond the first few, usually go around the map and pop up and attack the important buildings.

I did manage to finish it as Arteides though, I had a line of sonic tanks for defence and would make a mobile construction site and hide it behind my base for when the missile hit (which I never knew the name of bc I never got far enough in the other campaigns to use it). I had to wait until all the spice on the map was depleted and then go and mop up the enemy bases. I was never that proud, but my older nerdy friends always reacted with shock and disbelief that I had finished it.
Thank you for this response. I don't argue that the way to that peace hasn't been historical bloody, but the pandemics can't be blamed on the empires. Those were inevitable as population and trade grew, a byproduct of urbanization.

A lot of easy to digest content in this! Always great to see quality free material to help more people pick up machine learning and get involved solving problems using data science.

One thing I didn't see covered in depth here was feature engineering, which is the process of preparing your raw data for the machine learning algorithms. They cover it briefly in the chapter on "Practical Considerations", but anyone looking to apply ML in the real world should look into feature engineering more on their own.

One resource I recommend (and I am biased), is a python library for automated feature engineering called, Featuretools (https://github.com/featuretools/featuretools/). It can help when your raw data is still too granular for modeling or comprised of multiple tables. We have several demos you can run yourself to apply it to real datasets here: https://www.featuretools.com/demos.
Nope. You contracted Google not the end user. You have to go track down all this information and all the providers and then handle the GDPR downstream.
What I am saying is that the definition of an inefficiency in the market is the information that only a closed subset of the market has access to.

Let's take an example: China. While they keep the image of a purely capitalist environment, every company above a certain size is expected to have some sort of government control. That would be the inefficiency of that market, because at that point people stop making decisions based on what the company wants but rather what government wants. You can't have open access to the strategic planning by the government.

Besides, you're clearly trying to argue definitions rather than trying to take a step back and realising that I am arguing abstracts rather than specifics in the first place. In other words - what you're saying isn't denying what I said; it's just embodying the concepts in the real world.

For example: _any_ true real-life index fund would always need to trade at a certain point, and that has to be done by someone. So yes - an index fund is just a "glorified" version of a private fund; because people are still managing it at a certain point. But the reason it still makes money is because markets are efficient.

Or they were just unlucky in their in their interactions (I doubt many people would claim that all interactions in Open Source are good), or perceive some things differently than others, or ...

there's more than enough Open-Source maintainers complaining about bad interactions. Indeed many of the parents complaints are also reflected in the study as things people experienced as barriers to contributing. Luckily for many of them the good outweighs the bad, but that doesn't mean those for which it doesn't are automatically assholes.

It's especially bad to justify this broad brush with "minority experience".

> I have to point out that blablacar is not about solidarity, ecology or social relationships, to the contrary actually, it's about being a vampire draining money from solidarity and ecology and market domination.

So you just hate it because it's a company and it's making money. Right ?

> I mean carpooling was about solidarity and ecology, then blablacar seized the market and turned it into "no mobile phone, no credit card, no access to carpooling", "give us money first".

BlaBlaCar single-handedly created the huge carpooling market that now does exist in France for example. They didn't seize the market, people gave it to them. There are still other carpooling websites which you can use, and carpooling panels in events are still a common thing.

Up-front payment, not directly giving out people's phone number : you pretend this is bad practice, but this is exactly the security that was needed to bring the masses to carpooling, and as a matter of fact it did.

You seem to dislike that people would be ok in a win-win situation, where they both get paid for their expenses, and are happy to chat with other people while doing a small move for the planet. This is what's happening.

> I hate how blablacar turned something that was about helping each other and bringing people together into a capitalist profit making venture aiming for world market domination.

This is truly misguided. The opposite equivalent to my parent, but now with an anti-capitalist idealistic view of the world. Do you not see that? People are not into this ideological warfare of yours. The "world market domination" ... of carpooling? Do you realize how ridiculous that sounds?

Please find a mindset where you are able to leave BlaBlaCar be. Seriously, these are people too, and they are providing a great service. And I'm worried people, just like you do, are too prone to ranting on companies for all the bad reasons. The very reason you're using the excessive word hate, to me, seems to prove you're personalizing the entity and are a bit out of the rational realm in your claims.
The soap box has not been exhausted. It's not something you use once or twice and then give up on. And because the soap box has not been exhausted, the ballot box has necessarily not been employed to the full extent. The ammo box is for truly extreme situations such as when the results of the ballot box are being disregarded and the courts choose not to intervene or are incapable of meaningfully intervening.

Ironically, right now, you are using the soap box and not the ammo box. You're arguing your viewpoint online instead of killing people. That's a good thing, keep at it.

>"He's factually correct though."

It's not a fact that soap box options have been exhausted. It's merely your opinion that the soap box has been tried enough, to the point that giving up on trying to inform and persuade people is rational and/or ethical.

But... is that actually your opinion? You're here arguing online using your soap box, instead of waging a guerilla war against the system. So I think in actual fact you haven't given up on the soap box. Or at least you still see value in the soap box for purposes of inciting a rebellion?

> "20 percent of US children live in families with incomes below 50 percent of the national median income"

This is a bizarre metric. If richer families started having children at a higher rate, or poorer families slowed down, the problem would be fixed?

What if we simply cut the pay of the upper 50%, not even redistributing the income? That would lower median income, and therefore shrink the "less than 50% of median income" demographic, "solving" child poverty.
Nothing I can do can change the outcome either way, teddyh. I suspect you've already decided how you feel about me.

People are seeing a candid discussion of subjective experience as an indictment of theirs. This is another action I regret. I thought perhaps a related but dissenting viewpoint would have value to the conversation, but I guess not. This conversation itself is an example of the kind of negative experience I'm talking about.

What-if questions about the conclusions (as opposed to the axioms) of math being different rarely lead to insight, because they unpin too much. The results mostly depend on whatever else you had to change to keep your primary change from contradicting anything.

If all you changed was physics, the Taylor series thing would put quadratics right back into their position of importance.

"Previous studies have explored the role of training in the use of haptic devices. For
example, a study concerned with the acquisition of Braille by sighted learners has
demonstrated that a corresponding visual display was beneficial for the acquisition of
haptic Braille [13]. This result suggests the use of a visual display in the current study,
corresponding to the activation of vibrators on the tactual display. In addition, the efficacy
of correct-answer feedback for perceptual learning tasks is well-established [14],
indicating that correct-answer feedback should be employed in the learning procedure.
With the phonemic-based tactual display designed for conveying English words, we
consider two training approaches to training: phoneme-based and word-based [15]. The
phoneme-based approach, which operates on a “bottom-up” theory of learning, concentrates
on maximizing the individual’s ability to discriminate between and identify the
individual sound patterns of speech [15]. The word-based approach is based on a “topdown”
theory of learning. It bypasses the training of basic phoneme patterns and starts
with words directly [15]. Previous studies of speech training have employed single or
combined approaches [16-18]; however, these studies have not led to definitive conclusions
for choosing one approach over another."

Stop interpretting everything as a personal attack. It makes it seem like you were the bad apple, by immediately conflating contradictory statements and experiences into personal attacks. I would not want to work with such a person, in an open source project or otherwise.

I merely suggested that your bad experiences might have been because of the projects you worked with, so a general statement of "open source bad" might be a bit extreme because many others have had positive experiences. I'm sorry you had a shitty experience working on open source projects. That sucks for everyone. Not all open source projects have shitty leaders, but some do, and it's not always obvious which ones those are until you've invested some non-zero amount of time/effort into it.
Usually you throw everything and see what sticks. There are some obvious trends like if you're doing image classification, a convnet will beat just about anything else. There are problems which are particularly well suited to e.g. random forests and cases where you might want to use a simpler model which will run faster at the expense of a bit of accuracy.

In terms of neural nets, people have more or less done the hard work for you. Typically you'll want to take an empirically well-performing network like VGG, ResNet, Inception, etc and then re-train the top few layers. There is ongoing work in the field to try and train the structure of the network as well.

If you look at Kaggle, the vast majority of winners do so using ensembles. In a recent example - Iceberg or Ship - the winning team used a bit of feature engineering and apparently over 100 ensembled CNNs:

> We started with a CNN pipeline of 100+ diverse models which included architectures such as customized CNNs, VGG, mini-GoogLeNet, several different Densenet variations, and others. Some of these included inc_angle after the fully connected layers and others didn’t.

Facebook is probably the single most interactive and complex application out there... it's using React. There's also more to it than just the UI portion... there's also state management, and the unidirectional workflow, that you don't get in nearly as consistent a way with Vue as say Redux.
