I will have to look at code to be sure but the rule that */* trumps all is applied only when the request is not an ajax request. So if you are making ajax request then you should be good.

The problem is that opting out of mime type negotiation simply because there is a catch-all in there is wrong according to the specifications of HTTP.

In graph theory, a tree is a connected acyclic graph; unless stated otherwise, in graph theory trees and graphs are assumed undirected. There is no one-to-one correspondence between such trees and trees as data structure.

Stallman has also stated that considering the practical advantages of free software is like considering the practical advantages of not being handcuffed, in that it is not necessary for an individual to consider practical reasons in order to realize that being handcuffed is undesirable in itself.

Decentralized Social Networks vs. The TrollsDerek CaelinIn the summer of 2019, the alt-right social network Gab migrated to the decentralized "Fediverse" of social networks after being booted from mainstream financial services and hosting solutions. Almost immediately, Gab was met by a dedicated movement to isolate it. The movement was largely successful; within a year, the Gab CTO announced they would leave the Fediverse. This talk will cover how moderators, activists, and developers in the Fediverse used human moderators, strong moderation tools, representative codes of conduct, and no small amount of organization to promote healthy online spaces.We’ll review how some of the challenges faced by centralized platforms, which struggle with their own size and scale, have been addressed in networks of smaller, community run, more moderated servers. In the debate over how to make a healthier internet, the open platforms and open protocols in the model of the Fediverse may have some of the best resources to isolate bad actors, including Gab.

It’s understandable that in order to relax, users need to know they’re not being overheard – though there is a less playful side to this. If groups are perceived as a place to say what you really think, away from the constraints of public judgement or “political correctness”, then it follows that they are also where people turn to share prejudices or more hateful expressions, that are unacceptable (or even illegal) elsewhere.

The ongoing rise of WhatsApp, and its challenge to both legacy institutions and open social media, poses a profound political question: how do public institutions and discussions retain legitimacy and trust once people are organised into closed and invisible communities? The risk is that a vicious circle ensues, in which private groups circulate ever more information and disinformation to discredit public officials and public information, and our alienation from democracy escalates.

WhatsApp groups can not only breed suspicion among the public, but also manufacture a mood of suspicion among their own participants. As also demonstrated by closed Facebook groups, discontents – not always well-founded – accumulate in private before boiling over in public. The capacity to circulate misinformation and allegations is becoming greater than the capacity to resolve them.

Then when giving answers I'm even less certain. For example I see occasional how-to questions which (IMO) are ridiculously complex in bash, awk, sed, etc. but trivial in python, (<10 lines, no non-standard libraries). On such questions I wait and see if other answers are forthcoming. But if they get no answers, I'm not sure if I should give my 10 lines of python or not.

I went against the grain, applying other tools that people have written over the years to directly perform the job at hand which do not involve entering a program for awk or a shell to run, with answers like https://unix.stackexchange.com/a/574309/5132 and https://unix.stackexchange.com/a/578242/5132 . Others have done similar. https://unix.stackexchange.com/a/584274/5132 and https://unix.stackexchange.com/a/569600/5132 are (for examples) answers that show alternative tools to answers employing shell script and (yet again) awk programs, namely John A. Kunze's jot and rs (reshape), which have been around since 4.2BSD for goodness' sake!

There is an observable widespread tendency to give an awk answer to almost everything, but that should not be inferred as a rule to be followed, and if there's (say) a Python answer that involves less programming then surely that is quite on point as an answer for a readership of users.

Java may have been designed as a completely object oriented language, but when Java SE 8 was released in 2014, it added Lambda expressions (aka closures), which added some functional programming elements. Not every problem is best served by OOP, and by adding Lambdas, Java became more flexible. 

Ruby has some really nice libraries for working with linked data. These libraries allow you to work with the data in both a graph and resource-oriented fashion, allowing a developer to use the techniques that best suit his or her use cases and skills.

"that text has been removed from the official version on the Apache site." This itself is also not good. If you post "official" records but then quietly edit them over time, I have no choice but to assume bad faith in all the records I'm shown by you. Why should I believe anything Apache board members claim was "minuted" but which in fact it turns out they might have just edited into their records days, weeks or years later? One of the things I particularly watch for in modern news media (where no physical artefact captures whatever "mistakes" are published as once happened with newspapers) is whether when they inevitably correct a mistake they _acknowledge_ that or they instead just silently change things.

"AOO is not, and isn't designed to be, the 'super coolest open source office suite with all the latest bells and whistles,'" Jagielski continued. "Our research shows that a 'basic,' functional office suite, which is streamlined with a 'simple' and uncluttered, uncomplicated UI, serves an incredible under-represented community.

Due to social media, it's now easier than ever to make a defamatory statement. That's because social media services like Twitter and Facebook allow you to instantly "publish" a statement that can reach millions of people.

Lastly, in order for a statement to be defamatory, it must be unprivileged. You cannot sue for defamation in certain instances when a statement is considered privileged. For example, when a witness testifies at trial and makes a statement that is both false and injurious, the witness will be immune to a lawsuit for defamation because the act of testifying at trial is privileged.

The courts have called the web the most powerful communication tool on Earth, capable of making a person famous in a few minutes or destroying their reputation with a single click!

The meta charset information must also be the first child of the <head> tag. The reason this tag must be first is to avoid re-interpreting content that was added before the meta charset tag.

If you have worked with emails before, the idea of placing a script into an email may set off alarm bells in your head! Rest assured, email providers who support AMP emails enforce fierce security checks that only allow vetted AMP scripts to run in their clients. This enables dynamic and interactive features to run directly in the recipients mailboxes with no security vulnerabilities! Read more about the required markup for AMP Emails here.

These seem to be better reasons to support sub-nanosecond resolution. I think either storing picoseconds or storing sec fraction as 64-bit integer are better approaches than storing a rational. However, either change would be very invasive, and it seems unlikely to be worth the effort.

Performance optimizations are not free. They ALWAYS come with a cost but do NOT always come with a benefit to offset that cost.

Even having useCallback() returning the same function instance, it doesn’t bring any benefits because the optimization costs more than not having the optimization.

We need to teach youth to fish for mentors and we need to stock the pond with more mentors.

This model is the most flexible and open-ended of the four; your goal as an instructor is not to design a full-fledged semester of material, activities, and assessments. Rather, your goal is to work with your class to design and become a learning community, working collaboratively and individually towards your determined learning goals. For this to work you should have: a set of possible/preferred learning objectives for your classa library of course materials, preferably with as much as possible in digital formata suggested list of digital tools and technologies that you’re comfortable from with a list of possible assignment/project/assessment ideas that are related to your learning objectivesa willingness to experiment and invite your students into the teaching & learning process. At the onset of class you will need to facilitate a conversation among you and your students about how the class will unfold. This can be done in small groups f2f, via an online communication tool, or in a hybrid mix of both. As a community you should plan on addressing the following: what are our objectives as a learning community? what kind of work could we engage in to meet these objectives? what physical/virtual spaces would we like to work in? how/when do we want to meet in these spaces?how do we want to measure (assess) if an objective has been met?what rules and policies should govern our work? how will we work virtually and respect everyone’s boundaries and personal situations? how will we work f2f and respect public health recommendations and personal situations? You will probably need to spend at least the first 1-2 weeks answering these questions together and then designing a plan for your course. Make sure you and your students talk through various complications: what if the university’s policies about meeting f2f change? what if classes are forced to move entirely virtual/remote? what someone (students or professor!) gets sick?

Finally, these are NOT meant to be comprehensive. Instead, imagine these models along a continuum of opportunity. Your challenge is to determine where your courses could fit between and among the proposals.  

While the modifying version will occasionally be useful, in general, we should gently push people towards using non-modifying code.

Some may say that copied/not-copied goes without saying. I agree with Tallyrand: "If it goes without saying, it goes all the better for saying it."

So when Avdi took to air some of those grievances on Twitter, the natural thing happened that always happens when you feel your work is attacked: The core contributor group got defensive! That’s a mischaracterization! Where are the completed bug reports!? You know the drill, if you’ve ever worked on something, poured your heart into it, and then seen it criticized online. There’s that immediate, knee-jerk reaction of a sting. But it doesn’t have to sting.

Prefactoring is the application of experience to the creation of new software systems. Its relationship to its namesake refactoring is that lessons learned from refactoring are part of that experience.

Prismatic gets a percentage of the revenue increase that it generates for publishers, while developers pay a flat monthly fee based on usage, Cross says. It’s still working out pricing for hedge fund API usage. (As a point of comparison, the revenue model for the old Prismatic was the same as the current model for publishers. “We just meant for it to be more like Adsense/Adwords where we ran all this in our own consumer products too,” Cross notes.)

amplification hypothesis, conversely, does not predict a unified conflict 341 detection axis in the population. Instead, it makes a prediction that is exactly contrary to 342 the epiphenomenal view: that conflict should shift population activity along task-variable 343 coding dimensions, but in the opposite direction. That is, conflict is predicted to amplify 344 task-relevant neural responses

At the population level, then, the epiphenomenon hypothesis330 predicts that conflict should decrease the amount of information about the correct response 331 and shift neuronal population activity down along the axis in firing rate space that encodes 332 this response

As an engineer, it’s important to explore different technologies. It’s important to identify the tools available to tackle problems. And it’s important to expand your horizons because then you can look cool on your CV.

Some large tech behemoths could hypothetically shoulder the enormous financial burden of handling hundreds of new lawsuits if they suddenly became responsible for the random things their users say, but it would not be possible for a small nonprofit like Signal to continue to operate within the United States. Tech companies and organizations may be forced to relocate, and new startups may choose to begin in other countries instead.

e present a protocol for secure online com-munication, called “off-the-record messaging”, which hasproperties better-suited for casual conversation than do sys-tems like PGP or S/MIME.

"Off-the-Record Communication, or, Why Not To Use PGP"

In 2013, the Signal Protocol was introduced, which is based on OTR Messaging and the Silent Circle Instant Messaging Protocol (SCIMP). It brought about support for asynchronous communication ("offline messages") as its major new feature, as well as better resilience with distorted order of messages and simpler support for conversations with multiple participants.[11] OMEMO, introduced in an Android XMPP client called Conversations in 2015, integrates the Double Ratchet Algorithm used in Signal into the instant messaging protocol XMPP ("Jabber") and also enables encryption of file transfers. In the autumn of 2015 it was submitted to the XMPP Standards Foundation for standardisation.

the OTR protocol also reveals used MAC keys as part of the next message, after they have already been used to authenticate previously received messages, and will not be re-used

The answer, of course, is end-to-end encryption. The way this works is to remove any “man-in-the-middle” vulnerabilities by encrypting messages from endpoint to endpoint, with only the sender and recipient holding the decryption key. This level of messaging security was pushed into the mass-market by WhatsApp, and has now become a standard feature of every other decent platform.

The issue, though—and it’s a big one, is that the SMS infrastructure is inherently insecure, lending itself to so-called “man-in-the-middle attacks.” Messages run through network data centres, everything can be seen—security is basic at best, and you are vulnerable to local carrier interception when travelling.

When you make a call using Signal, it will generate a two-word secret code on both the profiles. You will speak the first word and the recipient will check it. Then he will speak the second word and you can check it on your end. If both the words match, the call has not been intercepted and connected to the correct profile

OK, so what about regular messages? Turns out they are not encrypted after all. Where Signal implements the security and privacy protocols right from the start, Telegram separates the two and offers an additional option. The problem is that not everyone is aware of the Secret Chat option and first-time users may send sensitive information in the regular chat window unknowingly.
