The big value that Rails adds is that it eliminates valueless choices. Most of the time, which logging library, ORM, view templating language, whatever doesn't really make all that much difference in terms of effectiveness and essentially come down to aesthetics.

When working with a framework that doesn't make those decisions for you, you end up with two big downsides - you waste time and energy arguing over which of these low-value choices you want to take, and new developers take longer to come up to speed with your particular architecture, since they need to learn each of the choices and how they are integrated, whereas in Rails it's obvious where everything is and how it's configured if you're familiar with the framework.

Bloat is also over-emphasized, particularly for the backend. You'll load the gems in memory, sure, but they're a fairly small footprint on their own and it's not like Rails is calling the parts of the framework it's not using (save maybe middleware, although most of that is useful for most web applications).

Yes, but my point is the majority of people I knew weren't "fooled" or "uneducated", they took it because it was what they wanted in spite of the danger and warnings. Banks certainly have a ton of responsibility for this, but I'm also not swayed but the slow-fade sob stories that people were "taken advantage of" by the banks either.
It's counterintuitive but a pretty well-known phenomenon. The finest cartoons provide a unique window into some aspect of human culture. The Simpsons, Futurama, King of the Hill—they all were entertaining, but the best episodes talked about something serious under the guise of humor. Science fiction is the same way. Star Trek isn't about aliens; it's about us.

Especially knowing the USA has been a thorn in Cuba's side since the 50's, repeatedly trying to kill Castro and undermine their economic system.

Americans live under constant propaganda from their own government, deployed by their own mainstream newspapers and TV media. Chomsky's 'Manufacturing Consent' is an eye opening look into the continuous war/regime change drum that's beating inside the USA.

This is just more the same, NY Times writing anti-Cuban articles as propaganda, with no evidence to back up their nonsense claims.
You don’t really duplicate that much between server and client. Yes, you have models on both. But the models do different things. Server is all about validation and querying a database to generate responses. Client side is all about user interaction.
How the Kessler Syndrome can end all space exploration and destroy modern life
I honestly can't bear opening up any sort of social media sites other than HN because it's all absolutely full of people "joking" about how miserable mere existence is and how funny wanting to die is.

There are many people out there with depression and who struggle with this everyday. Some people joke about it as a coping mechanism. But too many people are latching onto it as a joke, and I think they're turning it into their own reality. Seemingly everyone my age "jokes" all the time about wanting to die and it's becoming "normal" humor. That can't be healthy.

The first site that I got from searching for "buy wheelchair wheel" has what seems to be a decent range of off-road wheels. £144 for the cheapest, up to £320
for the end of the "cheap / mid". These loopwheels are on there, and have a similarly priced "fat wheel" to compete with.

2-4x the price doesn't seem too bad tbh; its specialist gear for a non-standard use case

Seems to be an extreme fringe position supported by a few articles from Buzzfeed, Jezebel, The Root, Reset Era, a YouTube video, and a reddit post with 7 votes. The rest of the results are about calling women "girls" which can be offensive for obvious reasons.

Perhaps you could point to a specific example where "it implies grouping women with female animals rather than grouping them together with men as human beings."
As usual, we never seem to be able to learn from the past, except by accidentally reinventing it under a different name. I wonder why the software industry is so uniquely stricken by such monumental hubris?

The whole Rails ethos is about admitting that your app isn’t really special and that what you’re doing is pretty similar to what everyone else is doing. So it’s better to decide on the best way to do things as a community so you don’t have to roll your own framework.
I don't think there's been any "getting angry as soon as people disagree" - he's substantially edited essays in response to critiques. It's pedantry and the presumption of malice that were probably the hard things to deal with, and he just realised that his time and energy would be better spent being an attentive father and partner. Good for him.

I have seen head first books being recommend by many. The only one I ever read half way though was one on design patterns and I regretted it. When I am learning something new, I want every sentence to be information heavy. So I could learn much more efficiently. Head first books just drag on and on with jokes, unnecessary conversations, cartoons and stuff. I literally gave up and Google searched each design patterns.

All my engineers books were pretty dry and to the point.
Definitely. I mean they are ultimately workers.

The comparison was between rats who could eat anytime and rats eating within a 10 hour window. What makes 10 hours the magic? Could it be 11, 12, 14 hours? Is it better if the window is 6 or 8 hours? Would it be different on a day in which the sun shone for 16 hours or 12 his? There is clearly something there but 10 hours seems arbitrary.
Yeah, our language model needs some work. We're constantly improving our engine though. Since we are manual transcription service, we can feed back the hand-made changes by humans back into our model and re-train it. Thanks for checking it out!

What options are available for iphone?
It’s been a few years since I’ve used Rails, but when I did, it always felt like within a year or two a new version of Rails would come out and I’d basically have to rewrite the site from scratch if I wanted to update.

I don’t know if the codebase has stabilized but the transition between 2.x to 3.x to 4.x was pretty rocky from my recollection. Hopefully it’s better, since Rails is probably the best framework to get a site up and running quickly.
Have you seen the movie "Shawshank Redemption"? It makes an interesting point about becoming institutionalized. There was an inmate that was released after ~50 years,he committed suicide because he couldn't adopt to living outside of the prison system.

What they call the loneliness epidemic these days is a bit like that. In fact,I would say loneliness is social imprisonment. For one reason or the other individuals end up lacking the skills needed to develop meaningful social relationships,the opportunities are there but the skills are lacking.

Much like becoming institutionalized, prolonged loneliness becomes a dependency in itself. At first you try everything you can to escape from the prison,then you learn to tolerate it,then you can't function outside of it.

I said all this to make one important point: For most people who experience prolonged loneliness,It's not lack of solutions or opportunities that keeps them lonely.

Not just in the US or the west but for all people,the importance of teaching children proper social skills needs to be communicated much like communicating the importance of good nutrition and hygeine has reduced preventable diseases throught the world.

For adults,I honestly don't know of any solution other than to continue creating opportunities for social interactions. It takes a lot of time,patience and practice to learn to make more friends and socialize once you settle down as a working adult.
It's not the same way that property rights are enforced. This is a common misunderstanding because of the term "intellectual property". In most countries the concepts of copyright, patent, trademark, trade secrets, etc are separate legal concepts with completely different regulations.

Copyright protects against the copying of works -- there is simply no analog of "copying a work" for physical property. You cannot "copy" a chair, or "copy" a table. You can make a new one from scratch based on the design of the old one, and assuming it has no patents, this would be completely legal.

Copyright also can place restrictions on redistribution of works, as well as modification (or even use) of works. This is something that is has no physical property laws associated with it -- the previous owner of a house cannot place restrictions on who you can sell your house to (or whether you can drill holes in the wall or where you can place your furniture). A publisher cannot restrict your ability to sell a book you bought to someone else second-hand.

The same argument can be drawn out for all of the other completely separate legal concepts.

Not to mention that "intellectual property" doesn't mirror the core concept of property -- it is based on scarcity. The reason why ownership of a house is important is because there is only one such house, and there must be a way to figure out who has the right to make executive decisions about that house. This is not how "intellectual property" operates. There simply is no scarcity, as ideas can be spread and copied without cost.
I'm not sure quite what you mean, but you can do the linear part of one layer all together, then the nonlinear part, etc.:

for weight,bias in layers:
a = sigmoid(np.dot(weight, a) + bias)
I think that's totally valid. As web applications grow you run more and more into the need for new features and the need for common solutions, things that Rails already give you. For example, when I wanted to try out jRuby for an application of mine, one point that made that impossible was the existing usage of the sqlite gem. Had I used activerecord I could have moved it over to the jdbc api with a simple added gem, Rails would have set me up for that solution. Or locales: The construction I added into my software basically re-implements how a Rails gem is used.

But that's also the value in it: After you constructed a big enough Sinatra application you understand why and how Rails is doing the things it does. I think that's very useful.
Your comment still doesn't make sense, even though you decided to choose a certain ADS and then latee decide on the implementation later based on empirical performance data, this is still not unusual. For (1) this is not how people write C. There are ADS libraries in C with which you wouldn't need need to use any DS that you can't change but this is not a usual way to write C code. This will also come with the overhead of pointer indirection and worse cache performance since all your objects will be void* stored in the DS (unless you m4 or macro generate your DS with all datatypes. This is what linux does for example, and I sometimes use this technique too, but this hardly the usual way to write C code). And (2) usually complex problems require special enough datastructures that it doesn't make much sense talk about ADSs. Everyone can code basic foobar with List interface then decide to use ArrayList or LinkedList based on performance. It's more interesting when the programmer decides to use a set, a hash map, a bloom filter etc to solve the problem as any other type wouldn't make sense.
Rails is tailored to a particular type of web application, and if your application strays far from this model it's probably not going to be a great fit. I don't think even the biggest Rails zealot would advocate building Google Maps in Rails.

The sweet spot that Rails covers, however, is a pretty common sort of web application - one in which you're primarily doing CRUD on different sorts of objects. If you treat every single application as a unique snowflake that needs a 100% bespoke collection of libraries to solve, you'll end up wasting a whole lot of time on architecture and library selection and not a lot of time on solving actual problems.

Basically, he developed what were regarded at the time as deductive "proofs" for the 'self-evident' truths of Catholicism, popularising some lateral thinking around the church's teachings which was a break from the contemporary norm of "this is true because the man in the funny hat who can read the big book says that's what the book says".

there is something called psuedo code. use your imagination.

> Anyway, selectAllBy() and selectOneBy() are not enough to be confortable

Like I said: 80%.

> SomeModel.findAllBySql() which most ActiveRecord implementations provide

So you are arguing that you should use a huge ORM code base, full of bugs, but then don't use it for anything complex, which means don't use 80% of the code, which is what "handles" all those complex edge cases.

Except then you have to have your team agree on what "complex" is, and half the team (who don't actually code anything complex) argue that you should use the ORM for everything, and then you end up in the sh-tshow that most amateur shops that build on ORMs are in.

Bottom line, ORMs are for low skill teams that basically don't know what they are doing, and if they ditched the ORM they might actually be able to learn to code decent systems.
Yes, it would be trivial. These kinds of power levels are probably enough to light an LED with it’s leads bent into a dipole.

It's very important to reduce unsprung weight, which this does. Vehicle suspension is extremely complicated with a huge number of interrelated variables. It is always possible to make suspension work better, but normally at the price of being more complicated/more expensive. This is a clever idea that isn't that complicated.

Is it true ? i remember reading that game communities are a very good place to meet new friends. Is it true ? why ?

Also are there any other good places online ?
>What time do you get home from work?

Depends on the job. Office jobs are nominally 9-5 but it's easy for employees to stay until 7pm or so in some places. Retail shops (anything from butchers and grocery places to supermarkets and shoe shops and electronics shops) close at 8-8:30pm (they usually open around 9am or a little later) -- but those have shifts too (e.g. those working there don't stay all day from 9am to 8:30pm, unless they're the owners).

Some places (usually the self-run ones) also close around 2:30/3:00pm and open again at 5:30pm or so.

>That sounds like an unreasonably long day if you have to be in work by 8am but you're still at a restaurant at 11pm.

Not "still at the restaurant at 11pm" - it's first sitting down at the restaurant at 11pm (they'd leave at 12:30 - 1am or so). They I guess you sleep for 6-7 hours or so and wake at 7 or 8.

That's the point of the source you requested and I provided: there are some formulations of stainless steel that are actually kind of ok in salt water despite most being poor.

No one is arguing that it's impossible to build a bear with solar panels. The point is that you can't slap a cheap panel from Alibaba on a float and have any assurance that it will work reliably. Thus costs go up and the whole idea may become infeasible.
If applied wrong, they can be. But the combination can be helpful.

Charitable skepticism leads you to asking questions about the content. If I say that coffee drinkers live 5 years longer on average, you can ask what in the coffee makes it happen, who did the study, how the study was conducted, etc, etc.

Rather than just saying the whole study is bullshit and dismissing it out of hand. That's more of a contrarian form of skepticism. And it's less useful in learning something.

For instance, if you ask those questions, some of the answers might lead you to something that is useful or interesting. Maybe something in the coffee binds to some receptor that enables blah blah blah (I'm making all of this up for the sake of example, mostly because I'm drinking coffee, so don't actually look for any of this information. It doesn't exist). Or maybe it is all hokum, which is good, because you don't like coffee anyway.

This may sound crazy but I think I have the solution: we make hats out of tin foil to block the microwaves.

Nice try
I find the occasional conversation with an Uber/Lyft driver something that many of my friends actively talk about. It does feel like a very unique social interaction that is distinct from (at least) my experience with taxis or any other form pf transit (i.e. more likely to sit in front, no barrier between rider and driver, more "casual" drivers)
> I’m not sure that tin foil hat can protect you from lousy journalism based on speculations without any evidence or even clues.

I’m certain it can, at least if it’s large enough to cover eyes and ears and thick enough to muffle sounds.
Agree. I was just talking about a pure technical issue of voice synthesize, and its implications to voice encryption. In other words, a communication-over-the-phone problem. I didn't mention nor intended to talk from a political or social perspective.

> Every time - every single time...

Just thought I'd provide some counter data here. I've built small services in Sinatra, which did not warrant the usage of Rails and never had to change anything, having them in fully functional operation for years.

I could have built these little apps in Rails, but I did not need it, never did, and my code/deployment/etc. is cleaner and smaller because of it.

Also these services have always been quite small (a few endpoints or functions), which is what I think Sinatra is best for.
Since v3 I’ve had no issues upgrading apps to the latest. As soon as a new release is available, I upgrade. V2 to v3 was pretty painful though..
Easy it’s casus belli to create (likely already exist) and use similar weapons.

An autonomous driving AI doesn't need to perform like a professional racing driver in order to improve safety.

The causes of most crashes are human fallibilities that AI doesn't suffer from:

An AI isn't tempted to drive drunk. It isn't distracted by incoming text messages. It doesn't get fatigued after driving for hours late at night. It doesn't suffer from road rage, and it isn't tempted to drive aggressively and take risks because it's running late for work. Just by avoiding these issues you've made driving a lot safer!

An AI also has reaction times that no human can match, has no blind spots and can track other vehicles in 360 degrees at once, and "see" through fog and rain using radar to detect obstacles.

Conversely, some of the things that are easy for humans are also the most difficult for AI to grasp: the social cues that we use to resolve pathing conflicts (eye contact, a wave, a blink of the headlights, etc), or our ability to intuitively predict the behaviour of other road users.

So while we may be some way yet from true, socially-accepted Level 5 autonomy, we're not far at all from semi-autonomous, driver-assistance technologies that significantly improve safety.

For detection, yes, it can be done by an extremely simple circuit. But you would need the raw I/Q sample data over a broad frequency range to perform a technical analysis to identify the nature of the microwave. Here's when a SDR comes handy.
I too find this recollection suspect. IRC used sideways emoticons like :). I don’t think it even had Unicode until recently, and using anything other than ascii has always been frowned upon. Sure, there were plenty of other types of ascii art, but shruggie is distinctly from the Unicode era.
There have always been people who wanted to be lonely though, just as there have always been people who wanted constant socializing. Both have their own problems when taken to extremes, i.e: Extreme socialization leads to group-think and collectivism[1], and extreme loneliness leads to despair and becoming overly withdrawn. I (personally) try to find a balance between the two, often withdrawing back into a hermit existence after some socializing.
