Her tirade about omega=+1 is odd because she talks about how it's incredibly anti-science, but doesn't even try to explain what the opposing view is (going so far as to say that she hasn't the foggiest). The first question I would want to know when evaluating the claim that omega=+1 is bad science is to hear the argument for it.

From my brief touches with cosmology, omega=+1 comes from measurements that the universe appears to have a flat topology (both from the size of structure in the CMBR and from a variety of other measurements). The flatness problem effectively is a fine-tuning problem that states if omega has slight deviations from +1 (of the order 1e-62) then the universe of today would not be able to sustain galaxies or other large structures. The measurement of _today's_ omega (omega_0) is also very close to +1 (which is what forces the initial condition limit). From that, it was concluded that if we accept the model of an accelerating universe, then the initial condition must be close to +1. Inflation is the proposed physical solution to explain why that is the case. To use the Newton analogy, you are backtracking the path of an arrow to find where it was fired from. To be clear, I personally don't like how hand-wavey cosmology is as a science, but pretending as though modern cosmologists just came up with a random "cult-like" belief that omega=1 is just ludicrous. [The author calls omega 'k'. While omega and k are related (k is the curvature, and can be used to deduce the critical density -- which omega is a fraction of) I'm not sure if that's quite right. But I'm speaking as a senior undergrad here, I might've missed something.]

As for the "possible weakness of a sub-argument", you can go to the reddit discussion of this particular post (others have linked it here) and see for yourself. It's quite a bit more than a "possible weakness of a sub-argument". Effectively the analysis is on her entire thesis (that the Bullet-cluster can be explained with modified gravity perfectly fine). The rest of the complains about modern cosmology are sub-arguments to justify why modified gravity should be considered.
>I wonder if this is a generational thing

Exactly.
I know about "instant gratification" being kind of bad, but even your moderate proposal is something like "gratification in half a decade" :)
This is all way too black-and-white thinking. You don't have one or the other of these like they are mutually incompatible. You should fear the failure of things that are too risky to even attempt, that's basic safety / risk-analysis. The fear-of-failure that I was talking about is the fear of failing at something that need not have ANY consequences besides the failure itself.

To put it another way: you should fear falling to your death when thinking about rock climbing. You shouldn't fear the failure itself but the painful death. Failure isn't worth fearing as a thing itself, only the consequences of failure are worth fearing.

If we had to pick one of your options, go with fearlessness. Be scared of actually dangerous things rather than of the abstract experience of failure.
> Now, perhaps the police are very good at their jobs and really do get the right guy 90+ of the time

Far from all arrests even result in charges. So, if most of the police failures are identified by the DA before charges are filed, it would still look this way even if the police false positive rate was high.

It's got to be tough spending a career working on ContentEditable. I don't know how these guys handle it.

Not only do you get to spend all day every day wading through the impossible pile of bugs, contradictions, mutually exclusive implementations and downright wackiness in the thing itself (did it seriously just allow the selection to include the opening DIV tag of the contenteditable itself???), but you get to have the same conversation every day with developers who haven't ever used ContentEditable and therefore consider it to be trivial.

"Why are you implementing the caret in javascript? Haven't you heard of ContentEditable?"

"Why is your simple WYSIWYG editor component seven megabytes of javascript? Wouldn't it be better to just use ContentEditable and be done with it?"

I only had to work with the technology for a few months. Years ago. And I'm still scarred today. Props to these guys for sticking it out!
Well, for starters you could have little 'Did you know?' pieces embedded in the text. Historical speeches need a ton of context to be assimilated properly. Immediate reference akin to a quick hyperlink based aside can give context without taking away from the continuity of the speech.

Yeah, that’s the new model. The review is on the S which is bigger.
There are a number of reasonable explanations for why those found guilty with public defenders face more severe consequences, even outside the ability to obtain more effective representation.

In particular, that is not balancing for the crimes of the accused. Certain crimes are committed disproportionately more often by certain demographics. Burglary, for instance, has the highest recidivism rate there is and is also going to be something engaged in almost exclusively by the sort of individuals that would not have the means to hire private representation.

Recidivism is also heavily dependent upon demographics, and once again individuals without means tend to return to crime more often than individuals with means. While each judge has their own 'style' of sentencing, in general an individual they believe less likely to return to crime is more likely to be sentenced to probation, than an individual who they see as more likely to return to crime.

Another reason prosecutors are incentivized to make (and accept) plea deals is because if every accused in the US demanded a trial by jury, our entire justice system would collapse in on itself which would necessitate immediate reform. We don't have anywhere near the resources to actually handle all the people we arrest and charge if they actually attempted to defend themselves. Kind of interesting in that in a way it's like a nationwide prisoner's dilemma.
Yeah, the old installable MSDN Library was really great. I loved how they approached each topic with three types of documentation: tutorials, concept overviews, and types-and-functions references. I still have the CDs on my bookshelf because I can't bring myself to throw them away. :)

Microsoft was really good at developer documentation.

Apps like Dash and websites like devdocs.io come close to the same experience, at least.
Not using dhparam? Dont like ECDH?

I wrote a similar amateur script years ago which has required updates from time to time to reflect new developments in the ongoing SSL saga.

This was started before anyone cared about SNI.

If the use case for the CA is a home network, I prefer using a local SSL-enabled proxy for connecting to both remote and local SSL-enabled endpoints. This lets me specify a short list of acceptable ciphers. It also permits me to use legacy, non SNI-enabled SSL/TLS clients. The remote and local hosts are "backends" that go in the proxy config file. I control DNS via local root or use HOSTS to redirect to the proxy.

If I was running multiple local SSL enabled devices/servers from the same local IP on a home network, then I believe I could just put these in the config file as backends listening on high, unprivileged ports. I do not believe I would need SNI because I could filter requests based on domain name and/or the filepath in the url.

The ultimate solution IMO would be an sslwrap type utility that has been revised to use more modern encryption, i.e. NaCl. Any application could then use NaCl instead of SSL/TLS, without having to modify the application. The NaCl author has menitoned several times that he has written such a utility and even said he will release it at some point.

IMO, that would be a big step in freeing us from the ills of SSL/TLS and the 3rd party CA system. Users would get easy-to-use, high quality, high speed cryptography without having to learn all of the SSL/TLS complexity, not to mention having to keep up with incessant bugs and security updates.
Yes in common sense.

But for node cluster's case, if we need to load a data set for a worker to serve request, it has to be loaded on each process. While the multi-threaded model will have only one copy.
> Why do cosmologists prefer numbers close to one?

Omega=+1 is preferred, because:

a) We measure Omega to be approximately 1 in the modern day. This indicates that the density of our universe is approximately the critical density (for a flat universe). Really, Omega=+1 means that our universe is flat.

b) In order for Omega to be approximately 1 _today_ in an expanding universe, it must have been even more close to 1 at t=0.

The only example of a parameter that she gave is omega. She didn't give any other examples, so it's quite a stretch to say that "cosmologists prefer numbers closer to one). Here's the wikipedia article on the problem: https://en.wikipedia.org/wiki/Flatness_problem. All of the points in that article were things we discussed in third-year cosmology as possible solutions to this fine-tuning problem.

> She is just saying initial conditions are not predictions of the same equation you plug them into.

The initial conditions are deduced by looking at modern observations and "winding back the clock" to see what set of parameters match the observed facts. I don't know what she's referring to "using a differential equation to predict its own initial conditions".

And you can create a probability distribution of possible initial conditions for omega, it's just very small (of the order 1e-62). Inflation is the proposed physical explanation for why that is the case.

To people that were driving 20 years ago and are now, it was pretty obvious without any statistics that something was wrong, for several years now. 25 years ago, I couldn't drive 500 km in summer without scraping off a thick crust of dead bugs on my windshield afterwards (it was even common to stop just for that). In the past few years, I've driven thousands of km across Europe in summer with barely a dead bug on my windows.
I recently switched from iTerm2 to Alacritty https://github.com/jwilm/alacritty. It does not have scrollback, splits, tabs and other fancy features. But for me, performance and snappiness is the most important feature (besides, I use Tmux for all those things mentioned).

For getting something close to i3 (you wont...?) on macOS I am using chunkwm https://github.com/koekeishiya/chunkwm.

I spent some time during the summer to get to know Linux using i3 (i3-gaps actually) with urxvt on a VirtualBox. I do recommend it!
You can't say generally that failure is costly. Tons and tons of failures cost nothing at all. Failures are inherent to learning. You can't generalize about the cost of failures, it totally depends on the type of failing.

Now, if you read the word as a state of being as in "being a failure" then you missed the entire point. The fixed mindset of seeing yourself in your identity as "a failure" or "a success" is stupid and should be discouraged. Failing is a verb, it's something you do or don't do in all sorts of cases all the time. It would be better to never think any of it is about "being a failure" in some personal identity way.

That seems like good stuff to pursue when you do focus on personal judgments, but I was emphasizing getting away from personal judgments. Instead of caring that you are a curious person (like an identifier), just be curious. It's a way to be now and tomorrow and on, a habit to have. We should get away from focusing on who you are which is what is a more fixed mindset.

I think it also largely depends on what the spec describes. XML for example is rather abstract and can be hard to follow, but SVG is quite easy to read and in my opinion much better than any 3rd-party explanation (primarily because it's complete and error-free).

It is worth noting that there likely isn't going to be a single cure for dyslexia in a similar way that there won't be a single cure for cancer. Dyslexia is really a collection of disorders that are grouped together because they share common symptoms but not necessarily common causes.

It sounds like this could help the stereotypical "see letters backwards" type of dyslexia. However there are numerous forms of dyslexia that have nothing to do with inverted images or difficulty identifying letters. For example, many dyslexics are able to write code or do math without the symptoms they might experience when reading/writing prose. That wouldn't be the case if the problem was based on vision.

Basically it allows for any Gofer on HN and similar forums to defend the idea "they are working on it" without any actual visible action.
I have the impression from some comments that the term "complexity" in a machine learning context is not well understood. It doesn't mean "complicated" from a human perspective at all, how difficult it is to grok the SVD algorithm vs NN. It actually refers to the complexity of the hypothesis set, which is, intuitively, the number of independent parameters to be learned. What matters in ML is the relative complexity of the hypothesis set (usually very high in deep learning) and the data complexity (sample size). If this relative complexity is too high, overfitting is likely (ie the noise is learned too), generalization bad, and regularization or a simpler model a must.

>whereas the main goal of textbooks is to convey information

True, but digital textbooks can be more than just 'text'-books. I'm not sure that field you had in mind, but in the scientific field, from chemistry to physics to biology, virtual models can help out a lot.

The entire point of doing lab work in these fields is so that they can associate what they _read_ in the textbook with what they can touch and play around with in the lab. So now I'm talking about bridging the gap. Instead of just conveying information, they can give experiences. Like vibrating a string in specific ways to study harmonic motion, to cutting open a plant's cell membrane to be able to zoom into each part of the plant cell in excruciating detail.

Again, I think we are just limiting ourself to what the conventional method of education has been. I think it is due for a change. With the internet revolution, you don't need a lecturer to be in front of you but you can rather watch a video and text your TA. With VR/AR Coming Soon™, experiences you and I have never had can be part of middle school curriculum. The resources we've put into software can pay off.

That's a problem with XML Schema, not XML.

A schema language in which subordinate values being presented as attributes vs. elements was a presentational option in the concrete XML representation rather than a dictate of the schema language would solve this simply. There are already multiple schema languages for XML; needing a better schema language doesn't begin to provide a reason for a different representation language, since schema and representation language are separate concerns.

> Small mammal organs have been successfully cryopreserved and thawed, and remained functional

Wow, nice rhetorical dodge there. No one cares too much if small mammal 'organs' have been successfully cryopreserved and revived because we can replace your kidney and you are still you. Tell me about the small mammal BRAINS that you have cryopreserved and revived with any evidence of retention of memories or prior training. Tell me about any nervous systems at all which you have successfully preserved and revived. Doesn't have to be a mammal, I would settle for an insect. Tell me about those please.

As a veteran of the border war I have zero understanding for the sentiment of "gratefulness that somebody else is willing to do a necessary and unpleasant job". I similarly struggle with the whole "lest we forget" thing in the UK.

The reason is that in my opinion it legitimizes war, violence and killing. It promotes patriotism, which is nationalism by another name, and a bus stop short of fascism. Fundamentally it suggests that one nation's people are worth more than anothers'. It's a neat trick, and I have a real problem with that.
